For purposes of calculating the aggregate market value of shares held by non-affiliates, we have assumed that all outstanding shares are held by non-affiliates, except for shares held by each of our executive officers, directors, and 5% or greater stockholders. In the case of 5% or greater stockholders, we have not deemed such stockholders to be affiliates unless there are facts and circumstances which would indicate that such stockholders exercise any control over our company, or unless they hold 10% or more of our outstanding common stock. These assumptions should not be deemed to constitute an admission that all executive officers, directors, and 5% or greater stockholders are, in fact, affiliates of our company, or that there are not other persons who may be deemed to be affiliates of our company.

As of March 13, 2026, there were 2,959,469 shares of common stock, par value $0.00001 issued and outstanding. Documents Incorporated by Reference: None.

INTRODUCTORY NOTE

Unless the context dictates otherwise, references in this Annual Report on Form 10-K to the “Company,” “Cardio,” “we,” “us,” “our,” and similar words are references to Cardio Diagnostics Holdings, Inc., a Delaware corporation, and its consolidated subsidiary. “Legacy Cardio” refers to Cardio Diagnostics, Inc. prior to the October 2022 Business Combination, which became our wholly-owned subsidiary as a result of that transaction.

Trade names and trademarks of Cardio referred to herein, and their respective logos, are our property. This Annual Report on Form 10-K may contain additional trade names and/or trademarks of other companies, which are the property of their respective owners. We do not intend our use or display of other companies’ trade names and/or trademarks, if any, to imply an endorsement or sponsorship of us by such companies, or any relationship with any of these companies.

The Company effected a 1-for-30 reverse stock split effective May 12, 2025 (the "Reverse Stock Split”). Unless otherwise indicated, all issued and outstanding stock and per share amounts referred to in this Annual Report on Form 10-K have been adjusted to reflect the Reverse Stock Split for all prior periods presented. Proportionate adjustments for the Reverse Stock Split were made to the exercise prices and number of shares issuable under the Company’s equity incentive plans and outstanding warrants, and the number of shares underlying outstanding equity awards and warrants, as applicable. See Note 1 for information and disclosures relating to adjustments related to the Reverse Stock Split.

CAUTIONARY NOTE REGARDING FORWARD LOOKING STATEMENTS

This Annual Report on Form 10-K contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, or the "Securities Act,” and Section 21E of the Securities Exchange Act of 1934, or the Exchange Act. The statements contained in this report that are not purely historical are forward-looking statements. Our forward-looking statements include, but are not limited to, statements regarding our or our management’s expectations, hopes, beliefs, intentions or strategies regarding the future. In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. The words “anticipates,” "believe,” “continue,” “could,” “estimate,” “expect,” “intends,” “may,” “might,” “plan,” “possible,” “potential,” “predicts,” “project,” “should,” “would” and similar expressions may identify forward- looking statements, but the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements in this Form 10-K may include, for example, statements such as the following:

the possibility that we may be adversely impacted by economic, business, and/or competitive factors;

our limited operating history makes it difficult to evaluate our business and prospects;

the success, cost and timing of our product development and commercialization activities, including the degree to which Epi+Gen CHD™ and PrecisionCHD™, our currently-available tests, are accepted and adopted by patients, healthcare professionals and other participants in other key channels may not meet our current expectations;

changes in applicable laws or regulations could negatively impact our current business plans, in particular with respect to regulation of laboratory-developed tests;

we may be unable to obtain and maintain regulatory clearance or approval for our tests, and any related restrictions and limitations of any cleared or approved product could negatively impact our financial condition;

the pricing of our products and services and reimbursement for medical tests conducted using our products and services may not be sufficient to achieve our financial goals;

we may be unable to successfully compete with other companies currently marketing or engaged in the development of products and services that could serve the same or similar functions as our products and services;

the size and growth potential of the markets for our products and services, and our ability to serve those markets, either alone or in partnership with others may not meet our current expectations;

we may be unable to maintain our existing or future licenses, or manufacturing, supply and distribution agreements;

we may be unable to identify, in-license or acquire additional technology needed to develop new products or services;

our estimates regarding expenses, future revenue, capital requirements and needs for additional financing may not be accurate;

we may be unable to raise needed financing in the future on acceptable terms, if at all;

we may be unable to maintain our listing on The Nasdaq Stock Market;

the ongoing or future impact from the coronavirus disease or other global health crises could cause significant economic and social disruption, and such impact on our business is uncertain; and

there are other risks and uncertainties indicated in this report, including those under the section entitled “Risk Factors” that will be included in any prospectus or prospectus supplement, and other filings that have been made or will be made with the SEC by us that could materially alter our current expectations.

The forward-looking statements contained in this Annual Report on Form 10-K are based on our current expectations and beliefs concerning future developments and their potential effects on us.

Risk Factor Summary

Our business is subject to numerous risks and uncertainties, including those highlighted in the section titled “Risk Factors,” which represent challenges that we face in connection with the successful implementation of our strategy and growth of our business. The occurrence of one or more of the events or circumstances described in the section titled “Risk Factors,” alone or in combination with other events or circumstances, may have an adverse effect on our business, cash flows, financial condition and results of operations. Such risks include, but are not limited to:

Risks Related to Our Business, Industry and Business Operations

We have a limited operating history that makes it impossible to reliably predict future growth and operating results.

	·	We have an unproven business model, have not generated significant revenues and can provide no assurance of generating significant revenues or operating profit.
	·	The healthcare commercialization process is inherently lengthy and subject to regulatory, reimbursement, evidentiary and behavioral factors, which, combined with clinical adoption of novel diagnostic technologies that frequently spans multiple years, results in a lengthy period from initial development to widespread utilization and resulting revenue, which, in some cases, may span a decade or more.

The market for epigenetic tests is fairly new and unproven, and it may decline or experience limited growth, which would adversely affect our ability to fully realize the potential of our business plan.

The estimates of market opportunity and forecasts of market growth included in this Annual Report on Form 10-K may prove to be inaccurate, and even if the market in which we compete achieves the forecasted growth, our business could fail to grow at similar rates, if at all.

If we are not able to enhance or introduce new products that achieve market acceptance and keep pace with technological developments, our business, results of operations and financial condition could be harmed.

The success of our business depends on our ability to expand into new vertical markets and attract new customers in a cost-effective manner.

Our growth strategy may not prove viable and expected growth and value may not be realized.

Our future growth could be harmed if we lose the services of our key personnel.

We may face intense competition, which could limit our ability to maintain or expand market share within our industry, and if we do not maintain or expand our market share, our business and operating results will be harmed.

Our business depends on customers increasing their use of our existing and future products, and we may experience loss of customers or a decline in their use of our solutions, particularly, but not exclusively, if we are unsuccessful in securing Medicare and other payor reimbursement.

We rely on a limited number of suppliers, contract manufacturers, and logistics providers for our tests.

We may be unable to scale our operations successfully.

As we grow the size of our organization, we may experience difficulties in managing this growth.

Our success depends upon our ability to adapt to a changing market and our continued development of additional tests and services.

Our Board of Directors may change our strategies, policies, and procedures without stockholder approval.

We may need to seek alternative business opportunities and change the nature of our business.

We may be subject to general litigation that may materially adversely affect us and our operations.

Our management expects to continue to devote substantial time to maintaining and improving its internal controls over financial reporting and the requirements of being a public company which may, among other things, strain our resources, divert management’s attention and affect our ability to accurately report our financial results and prevent fraud.

Risks Related to Our Intellectual Property

Certain of our core technology is licensed, and that license may be terminated if we were to breach our obligations under the license.

Our license agreement with University of Iowa Research Foundation (UIRF) includes a non-exclusive license of “technical information” that potentially could grant unaffiliated third parties access to materials and information considered derivative work made by us, which could be used by such licensees to develop competitive products.

Risks Related to Government Regulation

We conduct business in a heavily regulated industry, and if we fail to comply with these laws and government regulations, we could incur penalties or be required to make significant changes to our operations and tests or experience adverse publicity, which could have a material adverse effect on our business, financial condition, and results of operations.

If the U.S. Food and Drug Administration (“FDA”) were to implement rules regulating our tests, we could incur substantial costs and delays associated with trying to obtain premarket clearance or approval and incur costs associated with complying with post-market controls.

If our products do not receive adequate coverage and reimbursement from third-party payors, our ability to expand access to our tests beyond our initial sales channels will be limited and our overall commercial success will be severely limited.

Our licensed technology was made using government funding and may be subject to federal regulations under the Bayh-Dole Act. Compliance with Bayh-Dole is managed through UIRF and any lapse in reporting could negatively impact Cardio.

Risks Related to Our Common Stock

The price of our Common Stock likely will continue to be volatile like the stocks of other early-stage companies.

Because a substantial number of our currently outstanding shares of Common Stock are registered for resale, we may have difficulty raising additional capital when and if needed.

A significant number of shares of our Common Stock are subject to issuance upon exercise of outstanding warrants and options, which upon such exercise may result in dilution to our security holders.

We have never paid dividends on our Common Stock, and we do not anticipate paying any cash dividends on our Common Stock in the foreseeable future.

Sales of a substantial number of shares of our Common Stock in the public market by our existing stockholders could cause our stock price to decline.

Part I

Item 1.

Business

References in this report to “Cardio,” “we,” “us” or the “Company” refer to Cardio Diagnostics Holdings, Inc. References to our “management” or our “management team” refer to the officers and directors of Cardio Diagnostics Holdings, Inc.

Our Company

Cardio was formed to further develop and commercialize a series of products for major types of cardiovascular disease and associated co-morbidities, including coronary heart disease (“CHD”), stroke, heart failure and diabetes, by leveraging our Artificial Intelligence (“AI”)-driven Multi-Omics Engine™ (formerly known as our AI-Integrated Genetic-Epigenetic Engine^TM). As a company, we aspire to give every American adult insight into their unique risk for various cardiovascular diseases. Cardio aims to become one of the leading medical technology companies for enabling improved prevention, early detection and treatment of cardiovascular disease. Cardio is transforming the approach to cardiovascular disease from reactive to proactive and hope to accelerate the adoption of Precision Medicine for all. We believe that incorporating Cardio’s solutions into routine practice in primary care and prevention efforts can help alter the trajectory that nearly one in two Americans is expected to develop some form of cardiovascular disease by 2035.

Cardio believes that it is the first company to develop and commercialize epigenetics-based clinical tests for cardiovascular disease that have clear value propositions for multiple stakeholders including (1) patients, (2) clinicians, (3) hospitals/health systems, (4) employers and (5) payors. According to the CDC, epigenetics is the study of how a person’s behaviors and environment can cause changes that affect the way a person’s genes work. Unlike genetic changes, epigenetic changes are reversible and do not change one’s DNA sequence, but they can change how a person’s body reads a DNA sequence.

Cardio launched its first clinical test, Epi+Gen CHD™, a three-year symptomatic CHD risk assessment clinical blood test targeting CHD events, including heart attacks, in 2021 during the COVID-19 pandemic. As a result, the initial strategy for commercialization involved launching the test via telemedicine and in smaller provider practices such as concierge medicine practices. The volume of tests through these channels was minimal, and as the circumstances around COVID-19 pandemic improved, management re-vamped the Company’s go-to-market strategy to include other healthcare verticals and stakeholders beyond patients and small providers, including larger provider organizations, group purchasing organizations, employers, payors and life insurers. This new approach allowed Cardio to expand the reach of our solutions beyond the initial focus areas. Beyond the launch of Epi+Gen CHD, in March 2023, we announced the launch of our second product, PrecisionCHD™, an integrated epigenetic-genetic clinical blood test for the detection of coronary heart disease. The PrecisionCHD™ test is coupled to our Actionable Clinical Intelligence (“ACI”), a platform that offers new epigenetic and genetic insights to clinicians prescribing the test to personalize patient management and help improve chronic care management. In May 2023, we launched CardioInnovate360™, a research-use-only (“RUO”) solution to support the discovery, development and validation of novel biopharmaceuticals for the assessment and management of cardiovascular diseases. In February 2024, we announced the launch of HeartRisk™, a cardiovascular disease risk intelligence platform. We believe that our Epi+Gen CHD™ and PrecisionCHD™ tests are categorized as laboratory-developed tests, or “LDTs.” The new go-to-market strategy is also being implemented for these products. Despite long partnership and sales cycles, in some instances as long as 24 months, Cardio has been able to increase the number of provider organizations offering its tests and has continued the development of a more robust sales and partnership pipeline. In the fiscal year ended December 31, 2025, the focus of the Company remained on driving adoption of our clinical solutions, predominantly among providers, channel partners and employers. In addition, the Company made progress in its ongoing expansion to additional markets domestically and internationally with the first international expansion to India, partnering with channel partners such as YMCA of East Tennessee and Southdale YMCA to offer testing to its members and community, The Company also made progress in setting up our laboratory facility as a high complexity testing laboratory in compliance with the Clinical Laboratory Improvement Amendments (“CLIA”).

Cardio expects that sales and partnership cycles will continue to be long, especially with the current economic uncertainty. Our ongoing strategy for expanding our business operations and increasing revenue generation include the following:

	·	Leverage our CPT PLA codes and expand reimbursement efforts with both government and commercial payors;
	·	Develop additional products, including clinical tests for stroke, congestive heart failure and diabetes;
	·	Expand clinical and health economics evidence portfolio to continue to demonstrate value of products and increase reach;
	·	Offer laboratory services via our CLIA laboratory;
	·	Expand the adoption of our products across key channels, including health systems and self-insured employers;
	·	Explore additional market opportunities in the US;
	·	Explore partner-led international expansions like that in India;
	·	Explore opportunities to grow presence in India, including with local manufacturing;
	·	Scale our internal operations capabilities with a focus on improving efficiency and reducing our cost of goods sold; and
	·	Pursue potential strategic partnership(s) and/or acquisition(s) of one or more synergistic companies.

As of March 13, 2026, we have sold an aggregate 2,251,181 shares of our Common Stock under the Sales Agreement and may sell up to another $5,298,889 of our Common Stock through Craig-Hallum under the Sales Agreement.

Recent Regulatory and Judicial Developments Regarding LDTs

On May 6, 2024, the FDA published a final rule amending the definition of an in vitro diagnostic (“IVD”) device to include tests manufactured by a clinical laboratory. Pursuant to the rule, LDT, i.e., tests designed, manufactured, and used within a single CLIA-certified high complexity laboratory, would have been medical devices subject to FDA regulation under the Federal Food, Drug, and Cosmetic Act (“FDC Act”). The final rule also announced FDA’s intention to apply its medical device requirements to LDTs. Under the final rule, all LDTs, unless subject to a specific exemption, would have been subject to premarket authorization requirements (510(k), de novo classification, or PMA) for each LDT performed by the laboratory, and to postmarket registration and listing, medical device reporting, correction, removal, and recall, complaint handling, labeling, investigational device, and quality system requirements.

On September 19, 2025, the FDA formally rescinded its May 2024 final rule regulating LDTs as medical devices, following a March 31, 2025 federal court ruling. The U.S. District Court for the Eastern District of Texas found that the FDA exceeded its authority, reverting LDT oversight to Clinical Laboratory Improvement Amendments (CLIA). There has been no further pursuit by the current administration.

Industry Background

According to the American Heart Association (“AHA”), even though an estimated 80% of cardiovascular disease (“CVD”) is preventable, it remains the leading cause of death in the United States and globally. The AHA also reported that over 650,000 deaths in the United States each year are attributable to heart disease, which amounts to one in every four deaths. The Centers for Disease Control and Prevention (“CDC”) estimates that in the United States, one person dies every 36 seconds from CVD. Unfortunately, the incidence of CVD is expected to continue to rise with the AHA projecting that by 2035, nearly half of Americans will have some form of CVD.

CVD represents conditions that affect the heart and blood vessels such as coronary heart disease (“CHD”), stroke, and congestive heart failure (“CHF”). CHD is the most common type of heart disease and according to the CDC, was responsible for nearly 370,000 deaths in 2019. The National Center for Health Statistics reported that the prevalence of CHD is approximately 6.7%, and according to the AHA, over 20 million adults aged 20 or older in the United States have CHD. CHD is also the major cause of heart attacks. According to the AHA, every 40 seconds, someone in the United States has a heart attack, with over 800,000 Americans having a heart attack each year. The CDC reported that in 2020, stroke was responsible for one in six CVD-related deaths. The AHA estimates that every year, nearly 800,000 Americans have a stroke which is the leading cause of major long-term disability, with a stroke-related death occurring every 3.5 minutes. According to the AHA, over six million adults have heart failure and nearly 380,000 deaths in 2018 were attributable to heart failure. There are numerous risk factors that could increase an individual’s risk for CVD. Several key risk factors include diabetes, high blood cholesterol, and high blood pressure. For example, according to the CDC, over 34 million adults have diabetes and according to Johns Hopkins Medicine, those with diabetes are two to four times more likely to develop CVD. Alongside genetics, age, sex, and ethnicity, lifestyle factors such as smoking, unhealthy diet, physical inactivity, and being overweight can also increase the risk for CVD.

In addition to the enormous morbidity and mortality associated with CVD, the economic burden of CVD is also staggering as depicted in the figure below from the Cardiovascular Disease: A Costly Burden For America, Projections Through 2035 report by the AHA. CVD is the costliest disease in the United States and the economic burden associated with CVD is expected to continue to soar. According to the CDC Foundation, every year, one in six United States healthcare dollars is expended on CVD.

A graph of medical costs

AI-generated content may be incorrect.

The AHA reports that in 2016, the cost of CVD was $555 billion and is expected to rise to over $1 trillion by 2035. Of the $555 billion, $318 billion was associated with medical costs, and the remaining $237 billion with indirect costs such as lost productivity. By 2035, the medical costs associated with CVD are expected to increase 135% to $749 billion, while the indirect costs are expected to rise by 55% to $368 billion. Currently, among the various types of CVD, the medical costs of CHD are the highest at $89 billion and are expected to rise to $215 billion by 2035 as depicted in the figure below from the Cardiovascular Disease: A Costly Burden For America, Projections Through 2035 report by the AHA.

A table with text on it

AI-generated content may be incorrect.

To address this expected significant rise in human health and economic burdens, the United States healthcare market is seeking more efficient and effective methods to better prevent, detect, manage, and treat CVD. This same trend is playing out across developed nations around the globe as the burden of CVD continues to grow due to a rise in major risk factors such as obesity, poor diet and Type 2 diabetes.

This is consistent with the cardiovascular diagnostic testing market trends reported by Research and Markets in their Outlook on the Cardiovascular Diagnostic Testing Global Market to 2027 - Increasing Number of Insurance Providers Presents Opportunities press release published on July 4, 2022. They estimate that the Global Cardiovascular Diagnostic Testing Market is estimated to grow from $8.47 billion in 2022 to $12.41 billion by 2027, with a CAGR of 7.94%.

There are several healthcare tailwinds that are driving this expected growth and are expected to support the large-scale adoption of our solutions:

	·	The aging population: According to the Population Reference Bureau, by 2060, the number of Americans aged 65 and over is projected to more than double from 46 million to over 98 million. This demographic shift will result in increased demand for healthcare services in general and for CVD specifically because the risk for CVD increases with age. According to the AHA, the risk for CVD at age 24 is about 20% and more than doubles to 50% by age 45, with 90% of those over the age of 80 having some form of CVD.
	·	The rise of chronic diseases: Chronic diseases such as heart disease, cancer, and diabetes are rising in the United States. The rise of these conditions is further driven by less-than-ideal lifestyle choices such as smoking, an unhealthy diet, and sedentary behavior. As a result, better predictive and diagnostic tools are needed to get ahead of these conditions alongside the need for improved treatment and management of these conditions.
	·	The rise of costs associated with chronic diseases: Chronic diseases, including heart disease and cancer continue to drive up healthcare costs, placing a growing financial burden on employers, insurers, and the healthcare system at large. In the United States, the direct and indirect costs associated with CVD is expected to climb as prevalence increases. The financial strain is particularly evident in employer-sponsored health plans, where CVD is a leading driver of high-cost claims, absenteeism, and reduced productivity. As healthcare costs rise, self-insured employers, benefits consultants, payers, and providers are actively seeking cost-effective solutions to mitigate the impact of CVD. This includes early detection strategies, precision diagnostics, and personalized prevention programs that can identify at-risk individuals before costly acute events occur.
	·	The shift to value-based care: The shift to value-based care drives healthcare providers to focus on quality rather than quantity of care. The shift to value-based care is a crucial driver of growth for Cardio because it incentivizes health care providers to focus on providing quality care rather than simply providing more care. Cardio believes providers can tackle the costliest and deadliest disease category with its solutions while reducing costs.
	·	The growth of telemedicine: Driven largely by the COVID-19 pandemic, telemedicine is a growing trend in healthcare, as it allows patients to receive care from providers remotely. Remote, telemedicine-based preventative programs and tests can serve those who are already undergoing routine screening, but more importantly, expand reach to most Americans who currently are not receiving preventative healthcare, including rural and underserved populations. our evidence-based solutions can be deployed remotely, which is expected to further drive adoption by patients and clinicians.
	·	The adoption of Artificial Intelligence (AI): AI is increasingly incorporated into many aspects of healthcare, including administrative tasks, diagnosis and treatment. AI has the potential to improve the quality of care while reducing costs. Machine learning, which is a type of AI, is instrumental to our cutting-edge solutions, powering their clinical performance and differentiating them from other technologies for CVD.
	·	The rise of patient engagement: Thanks to technology, patients are becoming more engaged in their healthcare. They use online tools to research their conditions and treatments and are more likely to participate in their care. This includes demanding cutting-edge clinical tests that can help them better prevent chronic diseases such as CVD while improving the length and quality of life. As a result, healthcare providers and organizations that offer such services including our solutions are likely to have an edge over those who do not.

Our Strategy

	·	Building compelling evidence. Our AI-driven Multi-Omics Engine™ enables rapid design, development, and launch of diagnostic solutions resulting from over a decade of research studies. Our solutions that result from this technology, including our Epi+Gen CHD™ test for coronary heart disease event risk assessment and PrecisionCHD™ for the earlier detection of coronary heart disease, were developed through rigorous studies that are peer-reviewed and published and others that are being prepared for peer-reviewed publication in collaboration with leading healthcare and research institutions. In addition to the superior sensitivity of the Epi+Gen CHD™ and PrecisionCHD™ tests, the evidence bases for both the PrecisionCHD™ and Epi+Gen CHD™ tests also include an economic case to drive a more holistic and compelling argument for adoption.
	·	Expand product use cases. To continue to differentiate our products and their value propositions, we continue to invest in studies to expand their use cases. For example, with the PrecisionCHD™ test, we presented preliminary data at the American Heart Association and American College of Cardiology conferences on this test’s ability to detect non-obstructive form of coronary heart disease (INOCA) and predict mortality of acute coronary syndrome patients.
	·	Engaging experts and key stakeholders. At Cardio, we understand that engaging experts and key healthcare stakeholders is critical to realizing our solutions’ full potential and ensuring that these solutions reach as many people as possible.
	·	Prioritizing and executing strategic acquisitions. Our expertise at several intersections across biology, machine learning, lab assay development, and cardiovascular disease, provide an array of strategic acquisition opportunities to better serve the cardiovascular disease market by horizontally and vertically integrating across the cardiac care continuum.

Prioritizing payor coverage. We believe that to continue to grow the market traction of our solutions, we must secure broad payor coverage. We have already secured CPT PLA reimbursement codes for PrecisionCHD™ (0440U) and Epi+Gen CHD™ (0439U) and final CMS gapfill payment rates of $854 for both tests. For Medicare, we are currently pursuing coverage for these tests, which we believe is the critical first phase to accomplishing widespread reimbursement for our tests. For commercial payors, we are partnering with a third-party company and expect to have the capability to submit claims out-of-network beginning in Q2 2026. We are also continuing to build necessary evidence, and are pursuing pilots and strategic collaborations with payors. We expect that the process to secure broad coverage could take years, which means that our ability to generate meaningful revenue will continue to be constrained.

Evaluating FDA pathway. Cardio is evaluating an FDA regulatory pathway to enable broader access to our tests. The FDA pathway would enable Cardio’s tests to be performed broadly at many labs across the country. We are continuing to build our evidence base for this.

	·	Continued education. Changes to established workflows and clinical practice take time. However, we continue to invest in efforts to educate healthcare stakeholders, including physicians and decision makers, on our technology, tests and their value propositions. Such efforts include conference attendance, webinars, and one-on-one educational sessions.
	·	Targeting multiple revenue channels. To ensure that our revenue stream is diversified, Cardio has and will continue to target multiple revenue channels for which our solutions have compelling value propositions. This strategy includes, but is not limited to providers, health systems, and employers. We are also pursuing international expansions to further diversify revenue streams.

Launching synergistic products. To more fully address cardiovascular health, Cardio is leveraging our AI-driven Multi-Omics Engine™ to develop a series of clinical tests for major types of cardiovascular disease and associated co-morbidities, including stroke, congestive heart failure and diabetes. We have also started to develop additional synergistic products other than new clinical blood tests. Our first such product, HeartRisk™, is a cardiovascular disease risk intelligence platform, designed to augment our clinical blood tests.

Our Technology

At the core of Cardio is our proprietary AI-driven Multi-Omics Engine™, an engine invented and built by three key employees/officers for over a decade. Our technology enables rapid design, development and launch of new diagnostic solutions through the identification of robust integrated genetic-epigenetic biomarkers and their translation into clinical tests for cardiovascular disease and associated co-morbidities. This Engine consists of multiple layers. It begins with genome-wide genetic (single nucleotide polymorphisms or SNPs), genome-wide epigenetic (DNA methylation) and clinical data points. Using high-performance computing, ML/AI techniques and deep domain expertise in medicine, molecular biology and engineering, a panel of SNP-DNA methylation biomarkers are mined, modeled and translated into standalone laboratory assays.

AI-generated content may be incorrect.

As a result, our products, which are clinical tests, consist of two components. The first is a laboratory component, which involves epigenetic DNA biomarkers. Genetic biomarkers (“SNPs”) represent an individual’s inherited risk for the disease, have been reported to drive less than 20% of the risk for cardiovascular disease (Hou, K et al, Aug 2019, Nature Genetics) and do not change with intervention (i.e., static). Epigenetic biomarkers (DNA methylation) represent an individual’s acquired risk for the disease that is influenced by lifestyle and environment which is a larger driver for cardiovascular risk compared to genetics, is largely confounded by genetics and has been shown to change over time with intervention or changes in one’s lifestyle and environment (i.e., dynamic). The second is an analytical component, which involves applying a proprietary interpretive predictive machine learning model to predict risk and provide personalized insights to help clinicians tailor patient management. The combination of biomarkers and predictive machine learning model is unique to each clinical test we develop.

Our Products and Services

We have and will continue to leverage our AI-driven Multi-Omics Engine™ to develop a series of clinical tests for cardiovascular disease. As of March 2026, we have leveraged this Engine to develop two clinical products: Epi+Gen CHD™ and PrecisionCHD™.

We believe that our first product, Epi+Gen CHD™, is the first epigenetics-based clinical blood test capable of assessing near-term (three-year) risk for a coronary heart disease (“CHD”) event, including heart attacks, and our second product, PrecisionCHD™, is the first epigenetics-based clinical blood test for the detection of CHD.

Our PrecisionCHD test is accompanied by our provider-facing Actionable Clinical Intelligence™ platform, which maps a patient’s unique biomarker profile and other information onto modifiable factors such as diabetes, hypertension, hypercholesterolemia, and smoking, known to be critical drivers of coronary heart disease.

CardioInnovate360™ is a research use only (RUO) solution we launched to support the discovery, development and validation of novel biopharmaceuticals for the assessment and management of cardiovascular diseases.

In 2024, we launched our first software product, HeartRisk™. HeartRisk™ is a cardiovascular disease risk intelligence platform that combines insights from HIPAA-compliant anonymized and aggregated clinical cardiovascular data obtained through our Epi+Gen CHD™ and PrecisionCHD™ clinical blood tests, with industry and geographic data to enable real-time population-level cardiovascular disease (“CVD”) risk insights. These insights are customized for the stakeholder implementing our clinical solutions.

Clinicians’ Current Approach to Cardiovascular Disease

Currently, a patient’s risk for CVD is generally assessed using two common lipid-based clinical tests known as Framingham Risk Score (FRS) and ASCVD Pooled Cohort Equation (PCE).

FRS and PCE are 10-year CVD risk calculators that aggregate common clinical variables such as cholesterol and diabetes, demographics and subjective, self-reported information such as smoking status. For the early detection of CHD, tests that are routinely used in a provider setting include stress echocardiograms. These tests have several limitations and are less effective for several reasons:

	·	In a peer-reviewed published study by Cardio in collaboration with Intermountain Healthcare (Dogan, Meeshanthini & Knight, Stacey & Dogan, Timur & Knowlton, Kirk & Philibert, Robert. (2021). External validation of integrated genetic-epigenetic biomarkers for predicting incident coronary heart disease. Epigenomics. 13. 10.2217/epi-2021-0123), we found that for predicting the three-year risk for a coronary heart disease event such as a heart attack, the average sensitivity of FRS and PCE was 44% in men and 32% in women. This means that for every 100 men and 100 women deemed "at-risk” for a coronary heart disease event, the test only correctly identifies 44 men and 32 women.
	·	In a peer-reviewed published study by Cardio in collaboration with Intermountain Healthcare and University of Iowa Hospitals and Clinics (Philibert, Robert & Dogan, Timur & Knight, Stacey & Ahmad, Ferhaan & Lau, Stanley & Miles, George & Knowlton, Kirk & Dogan, Meeshanthini. (2023). Validation of integrated genetic-epigenetic test for the assessment of coronary heart disease. Journal of American Heart Association. 12:e030934. DOI: 10.1161/JAHA.123.030934), we found that the overall average area under the curve, sensitivity, and specificity in three independent test cohorts for detecting coronary heart disease were 82%, 79%, and 76%, respectively.
	·	In a peer-reviewed published study by Cardio in collaboration with Intermountain Healthcare and University of Iowa Hospitals and Clinics (Philibert, Robert & Dogan, Timur & Knight, Stacey & Ahmed, Ferhaan & Lau, Stanley & Miles, George & Knowlton, Kirk & Dogan, Meeshanthini. (2023). Validation of an integrated genetic-epigenetic test for the assessment of coronary heart disease. Journal of American Heart Association. 10.1161/JAHA.123.030934), we found that for predicting the presence of coronary heart disease, PrecisionCHD had an 80% sensitivity for men and 76% sensitivity for women.

	·	The fasting requirement for current tests could be cumbersome for patients to comply, and the lack of fasting could affect test results.
	·	The patient care plan that results from these tests generally lack personalization.
	·	Lipid-based risk assessment tests depend on self-reported, subjective information such as smoking status from patients, and inaccurate information could affect the accuracy of test results.

	·	Undergoing these tests requires an in-person clinic visit to collect blood samples and other necessary data points such as blood pressure, which may delay or prevent access to primary prevention, e.g., for those who are unable to make time for the visit, have transportation issues or live in rural areas are likely to delay primary prevention altogether. Similarly, to undergo a stress echocardiogram for instance, an in-person visit is required, and such a visit can take weeks to schedule that could delay care for patients especially if they are experiencing symptoms such as chest pain.
	·	Commonly used risk assessment tests were also developed predominantly using data from men and therefore, may be less effective for women.

Epi+Gen CHD™ is the Only Epigenetics-based Clinical Test for Coronary Heart Disease Event Risk Assessment

Epi+Gen CHD™ is a scientifically backed clinical blood test that is based on an individual’s objective genetic and epigenetic DNA biomarkers for assessing the three-year risk for a coronary heart disease event such as a heart attack. In a peer-reviewed study done in collaboration with Intermountain Healthcare (Dogan, Meeshanthini & Knight, Stacey & Dogan, Timur & Knowlton, Kirk & Philibert, Robert. (2021). External validation of integrated genetic-epigenetic biomarkers for predicting incident coronary heart disease. Epigenomics. 13. 10.2217/epi-2021-0123), this test demonstrated a 76% and 78% sensitivity for men and women, respectively, for three-year CHD risk. This means that for every 100 men and 100 women deemed "at-risk” for a coronary heart disease event, the test correctly identifies 76 men and 78 women. In comparison, the average sensitivity of the Framingham Risk Score and the ASCVD Pooled Cohort Equation was found to be 44% and 32% for men and women, respectively. The performance of the test in this study was evaluated across two cohorts that were independent of each other. One cohort was used for the development of this test, and the other was used to independently validate the performance of the test, showing Epi+Gen CHD™ to be approximately 1.7 times and 2.4 times more sensitive than the current lipid-based clinical risk estimators in men and women, respectively. In another peer-reviewed study focusing on the cost utility of Epi+Gen CHD™ (Jung, Younsoo & Frisvold, David & Dogan, Timur & Dogan, Meeshanthini & Philibert, Robert. (2021). Cost-utility analysis of an integrated genetic/epigenetic test for assessing risk for coronary heart disease. Epigenomics. 13. 10.2217/epi-2021-0021), this test was associated with up to $42,000 in cost savings per quality adjusted life year and improved survival compared to the ASCVD Pooled Cohort Equation. In another peer-reviewed study, (Philibert, Willem & Andersen, Allan & Hoffman, Eric & Philibert, Robert & Dogan, Meeshanthini. (2021). The reversion of DNA methylation at coronary heart disease risk loci in response to prevention therapy. Processes. 9, 699. https://doi.org/10.3390/pr9040699), DNA methylation of this test was shown to change within 90 days of intervention in the form of smoking cessation, demonstrating that this test could potentially also be leveraged to evaluate the effectiveness of interventions.

The blood-based version of this test was introduced for market testing in 2021. The pricing of the test varies based on factors such as organization type and test volume. The price of the test and revenue streams could change in the future depending on market forces and payor requirements, as well as on the customer and the region in which the test is being sold. We are continuing to build additional clinical and health economics evidence to pursue payor coverage. A key first step in expanding critical payor coverage is to have this test be assigned a CPT PLA code, and the American Medical Association awarded the Epi+Gen CHD™ a CPT PLA code, 0439U. This test received a final CMS gapfill payment rate of $854 in 2025.

We believe that the Epi+Gen CHD™ test can benefit numerous healthcare stakeholders. For instance, we believe that this test will enable clinicians to identify patients at-risk in the near-term for CHD-related events, including a heart attack, and utilize actionable insights from this test to provide more personalized care for their patients to help prevent the event and improve outcomes. These actionable insights are conveyed via our provider-facing Actionable Clinical Intelligence™ platform, which maps a patient’s unique biomarker profile and other information onto pathways and modifiable drivers of coronary heart disease. In addition to clinicians, we believe that this test can enable healthcare organizations and payors to reduce the cost of care, and employers to understand and better manage business risks including healthcare costs. Insights for these stakeholders upon leveraging the Epi+Gen CHD™ test are provided via our new software product, HeartRisk™, which is a cardiovascular disease risk intelligence platform. The pricing for this platform will be customized based on the organization type and size, and use case.

PrecisionCHD™ is the Only Epigenetics-based Clinical Test for the Early Detection of Coronary Heart Disease

PrecisionCHD™ is a scientifically backed clinical blood test that is based on an individual’s objective genetic and epigenetic DNA biomarkers for the detection of coronary heart disease. In a peer-reviewed published study by Cardio in collaboration with Intermountain Healthcare and University of Iowa Hospitals and Clinics (Philibert, Robert & Dogan, Timur & Knight, Stacey & Ahmad, Ferhaan & Lau, Stanley & Miles, George & Knowlton, Kirk & Dogan, Meeshanthini. (2023). Validation of integrated genetic-epigenetic test for the assessment of coronary heart disease. Journal of American Heart Association. 12:e030934. DOI: 10.1161/JAHA.123.030934), this test demonstrated an overall average area under the curve, sensitivity, and specificity in three independent test cohorts for detecting coronary heart disease of 82%, 79%, and 76%, respectively. The average sensitivity for men and women was 80% and 76%, respectively. This means that for every 100 men and 100 women deemed “to have” coronary heart disease, the test correctly identifies 80 men and 76 women. In comparison, the most commonly used and least invasive test for detecting coronary heart disease, exercise ECG, has a sensitivity of only 58%. The performance of the test in this study was evaluated across three cohorts that were independent of each other. One cohort was used for the development of this test, and the other two were used to independently validate the performance of the test. Based on the known sensitivity of exercise ECG, PrecisionCHD™ is approximately 1.4 times and 1.3 times more sensitive than an exercise ECG in men and women, respectively, for detecting coronary heart disease. In another peer-reviewed study, (Broyles, Damon & Philibert, Robert. (2023). Precision epigenetics provides a scalable pathway for improving coronary heart disease care globally. Epigenomics. 10.2217/epi-2023-0233), the global scalability of PrecisionCHD was outlined in comparison to commonly used coronary heart disease tests such as exercise ECG and CCTA. Similar to the Epi+Gen CHD™ test, a peer-reviewed study was conducted to evaluate if the DNA methylation biomarkers of PrecisionCHD could be potentially leveraged to evaluate the effectiveness of interventions. In this peer-reviewed study, (Philibert, Robert & Moody, Joanna & Philibert, Willem & Dogan, Meeshanthini & Hoffman, Eric. (2023). The reversion of epigenetic signature of coronary heart disease in response to smoking cessation. Genes. 14, 1233. https://doi.org/10.3390/genes14061233), DNA methylation of this test was shown to change within 90 days of intervention in the form of smoking cessation.

The blood-based version of this test was introduced for market testing in 2023. The pricing of the test varies based on factors such as organization type and test volume. The American Medical Association awarded the PrecisionCHD™ a CPT PLA code, 0440U. This test received a final CMS gapfill payment rate of $854 in 2025. The price of the test and revenue streams could change in the future depending on market forces and payor requirements, as well as on the customer and the region in which the test is being sold. We are continuing to build additional clinical and health economics evidence to pursue payor coverage.

Product Pipeline

We have several other tests in our product pipeline at various stages of development for congestive heart failure, stroke and diabetes. However, as a company in the early stages of its development, we continuously reevaluate our business, the market in which we operate and potential new opportunities. We may modify our product pipeline, seek other alternatives within the healthcare field in order to grow the Company’s business and increase revenues. Such alternatives may include, but not be limited to, combinations or strategic partnerships with other laboratory companies or with medical practices such as hospitalists or behavioral health.

Our Market Opportunity

Cardiovascular disease (“CVD”) is the leading cause of death in the United States, accounting for one in four deaths. Despite being largely preventable, the American Heart Association projects that by 2035, nearly 45% of Americans will have some form of CVD. One of the key ways to address the prevalence of CVD is to shift the approach for CVD from reactive treatment to proactive prevention and earlier detection. As such, technologies that can more precisely assess the risk for and detect CVD before symptoms emerge or a catastrophic cardiac event occurs becomes even more critical.

According to Research and Markets in their Outlook on the Cardiovascular Diagnostic Testing Global Market to 2027 - Increasing Number of Insurance Providers Presents Opportunities press release published on July 4, 2022, the Global Cardiovascular Diagnostic Testing Market is estimated to grow from $8.47 billion in 2022 to $12.41 billion by 2027, with a CAGR of 7.94%. The increasing prevalence of cardiovascular diseases, technological advancements in cardiovascular disease diagnostics, and the growing number of initiatives to promote cardiovascular disease testing are the major factors driving the growth of this market.

Our principal mission is to enable better detection of the presence and risk of major cardiovascular diseases through a series of clinical tests developed by leveraging our proprietary AI-driven Multi-Omics Engine™. Our initial product, Epi+Gen CHD™, is a highly sensitive and accessible clinical test for three-year coronary heart disease (“CHD”) event risk assessment, including risk for a heart attack. Our second product, PrecisionCHD™, is a highly sensitive and accessible clinical test for the detection of CHD.

Using data from the US Census Bureau, test intended use and disease prevalence, Cardio estimates that 146 million adults could potentially benefit from our Epi+Gen CHD™ test, and 60 million adults for our PrecisionCHD test. Using the final CMS gapfill pricing of $854/test as a basis, the US addressable market equates to ~$125 billion for Epi+Gen CHD™, and $51 billion for PrecisionCHD™. This total addressable market does not account for variations in test price, including self-pay, pilot pricing, discounts and different payment rates by different payors. It also does not account for re-testing for patients over time.

Go-To-Market Strategy for Epi+Gen CHD™ and PrecisionCHD™

Our current go-to-market (“GTM”) strategy is predominantly a product-led innovation growth strategy that emphasizes enterprise-wide adoption across key healthcare sub-verticals with a particular emphasis on deeply centralized key opinion and health trend leaders like innovative providers, health systems, and employers.

Healthcare Sub-Vertical Priorities for Epi+Gen CHD™ and PrecisionCHD™

By assessing the risk for a heart attack early and/or detecting CHD early to potentially avert a heart attack, we believe that the clinical and economic utility of the Epi+Gen CHD™ and PrecisionCHD™ tests will support their commercial adoption. We believe that Epi+Gen CHD™ and PrecisionCHD™ can address a significant addressable market opportunity even before these tests are covered and reimbursed by payors. While we believe that such coverage and reimbursement would be necessary to gain widespread adoption, obtaining such coverage and reimbursement from federal and private payors may take several years, if it is obtained at all. We intend to focus on the following key channels as part of our GTM strategy:

Innovative Health Systems

As innovative health systems diversify their business models and care delivery pathways, there is a renewed emphasis on using precision medical technologies to better manage expensive and chronic conditions, including CHD. By assessing the risk for a CHD event including a heart attack before it occurs, Epi+Gen CHD™ has the potential to improve population health. We believe that the improved performance of our test compared to other risk calculators, coupled with evidence of cost savings and enhanced survival, will drive the adoption of Epi+Gen CHD™ by health systems to continue improving the health of their patients. Similarly, with PrecisionCHD™, innovative health systems are able to help test their patients detect CHD earlier with a simple blood test, potentially leading to better patient outcomes.

Physician-Directed Channels, Including Concierge Practices

Early adoption is driven by practices committed to innovation in medicine for patients who are more focused on preventive health and wellness and have the financial means to pay out-of- pocket for concierge subscription services. There is a convergence in innovative providers, health-conscious consumers, and best-in-class tests and technologies in concierge medicine practices or other similar practices to provide on-demand elite personalized and readily accessible healthcare. With an estimated 2,000 to 5,000 concierge practices in the United States, there is robust growth in high-end healthcare services with an equal demand for innovative diagnostic tools. Additionally, concierge practices are not price-sensitive, so reimbursement is not a top priority.

Employers

Early adoption in the employer space is likely to be driven by self-insured employers and employers looking to provide employee perks relevant to health. Self-insured employers are consistently seeking solutions to help manage their biggest cost centers such as heart disease. In a post-pandemic world, the health and wellbeing of employees are also top-of-mind for many employers to ensure that their employees are healthy and productive. Employers view healthcare investments as another investment in the business. Employers leveraging innovative diagnostic solutions can connect better health for employees to drive overall business objectives and have a competitive advantage in managing business risks while attracting and retaining talent.

Telemedicine and Marketplaces

Many Americans are concerned about being proactive with their health needs. Understanding their personalized risk with tests at the forefront of medicine is crucial for those with financial resources. According to the U.S. Census Bureau based on the 2020 census, there are nearly 44 million households that earn $100,000 or more annually. We expect high-earning Americans who are proactive about their health to constitute the initial attainable market.

Sales and Marketing for Epi+Gen CHD™ and PrecisionCHD™ with a Focus on Strategic Channel Partnerships

While our overall sales and marketing initiatives will span the gamut across traditional, print, and digital media, our primary sales and marketing strategy consists of the branding, collaboration, co-marketing, and co-sales opportunities involved in strategic channel partnerships. By prioritizing strategic channel partnerships, we believe we can accelerate our market penetration into the key healthcare sub-verticals we intend to prioritize for our growth. The key to our efforts is a well-defined and executed channel partnership integration strategy that will serve to accelerate the sales cycles for each of our distribution channels. The sales cycles are generally defined as the period in which such distribution channel will turn over its inventory of our tests, which may vary for each distribution channel. Utilizing and developing such strategic channel partnerships, we believe, will generate revenue in a myriad of ways including larger contracts for our Epi+Gen CHD™ and PrecisionCHD™ clinical blood tests, and bundling our solutions alongside other synergistic technologies, services, and products.

Strategic channel partnerships are key for the growth of our solutions. There are several key revenue and strategy benefits to developing a robust channel partnership strategy, including:

Defensibility and Displacement

Strategic channel partners may have exclusivity agreements for Epi+Gen CHD™ and PrecisionCHD™, which forecloses distribution channels to potential competitors.

Distribution and Network Effects

Channel partners under consideration for Epi+Gen CHD™ and PrecisionCHD™ strategic partnerships have large, related healthcare and life science networks that we expect to leverage as part of the relationship.

Bi-Directional Value

The cardiovascular disease space is of paramount concern to stakeholders across the healthcare continuum; the scale of the disease across the population and the associated costs ensures that addressing cardiovascular disease from a payment, cost, patient outcome, and prevention standpoint for stakeholders across the spectrum will continue to be a priority.

Pricing Differentiation

The economics of each channel partnership can be crafted independently to offer each strategic partner a per-unit cost relevant to the size of their network.

Complementary Goods

Bundling Epi+Gen CHD™, PrecisionCHD™, HeartRisk™ and future Cardio solutions alongside complementary clinical, analytics, treatment pathways, and services-consulting for primary prevention optimization with key partners expands the ROI of the investment in our solutions.

Hiring and Talent to Accelerate Growth

Our growth strategy will require investment in internal and external healthcare enterprise sales, marketing and deep customer insights. By combining best-in-class revenue operations technologies with seasoned healthcare sales and marketing experts, we believe we can quickly scale the selling approaches we have outlined and validated to transform the cardiovascular healthcare experience, driving revenue and increased margins. New hires will be targeting the entire continuum of revenue needs, including opportunity identification, campaign design, and execution.

Manufacture/Supply Chain

The content of the sample collections kits for both Epi+Gen CHD™ and PrecisionCHD™ are identical, and we rely on third-party suppliers for kit contents required to collect and transport a blood sample to the lab for processing. These are commonly used supplies that are and can be sourced from multiple distributors. Upon sourcing these contents, they are assembled into lancet- based and vacutainer-based sample collection kits internally and fulfilled. We intend to maintain an inventory of fully assembled kits to meet expected demand for at least six months. However, since there are no particular or unique assembly protocols and assembly is handled internally, the lead time to assemble additional sample collection kits would be minimal after the contents are sourced.

Proprietary genetic and DNA methylation components are sourced from large manufacturers and manufactured under good manufacturing practices (“cGMP”). There are alternative manufacturers for each of these components, and no additional lead time is expected. Laboratory assays that are manufactured under cGMP to specifications are expected to be available to meet anticipated demand for at least six months.

Both the Epi+Gen CHD™ and PrecisionCHD™ clinical blood tests currently are offered as LDTs through our newly established laboratory with the appropriate Clinical Laboratory Improvement Amendments of 1988 (“CLIA”) certification and state licensure. The initial CLIA survey was conducted by a CLIA compliance manager, which found no deficiencies.

Our Competitive Strengths

Innovation is the key to success. In the rapidly moving cardiac diagnostics space, we believe that we have the team, differentiated technology, and deep technical and business expertise to deliver a market differentiating suite of products for our customers to address unmet clinical needs in the cardiovascular space and help us dominate our market.

The pillar of our strategy has been innovation, from the onset with our technology development and intellectual property that account for future growth, to our commercialization and partnership efforts that bring together key healthcare stakeholders.

We believe that, among other reasons, the future belongs to Cardio based on the following competitive strengths:

Technology and products are strongly backed by science.

Our technology and products stem from over a decade of rigorous scientific research by the founding team in collaboration with other clinical and research experts from leading organizations. Our founding team consist of experts in machine learning approaches in healthcare and in epigenetics with highly-cited peer-reviewed publications. The technology and products are developed and validated with extensive clinical data. The key findings have been published after undergoing stringent independent third-party peer review.

Broad intellectual property portfolio protects our current and future products and their applications.

As of March 2026, our patent portfolio includes seven patent families, which encompasses two issued patents in the U.S., as well as issued patents in United Kingdom, France, Germany, Italy, Switzerland, Ireland, Hong Kong, Australia, China, India, and Japan, five pending U.S. patent applications, one pending PCT International application, and forty-five patent applications pending worldwide, which are generally directed to methods and compositions for detecting biomarkers associated with cardiovascular disease and diabetes for diagnosis and other applications. In addition, we have extensive trade secrets and know-how, including algorithms and assay designs, that are critical for the continued development and improvement of our current and future products.

Big data and artificial intelligence (machine learning) expertise drive future product development.

Our expertise in processing billions of clinical genotypic, epigenetic and phenotypic data points to generate critical insights allows us to continue to develop innovative products.

Proprietary cutting-edge AI-driven Multi-Omics Engine™ accelerates product development.

We have built a proprietary AI-driven Multi-Omics Engine™ that is made up of layers of big data, our algorithms informed by biology and its expert domain knowledge that was designed and built over more than a decade and can be leveraged to enable rapid design, development and launch of new diagnostic solutions.

Multiple potential product offerings with strong value propositions for key healthcare stakeholders.

We have built a robust product pipeline for various types of cardiovascular disease and other indications that leverage our AI-driven Multi-Omics Engine™ to continue to build market traction. We believe that our current and future products have strong value propositions for various key stakeholders in healthcare. As a result, we believe that our customers will adopt and champion our products.

Products that can potentially drive value in multiple ways.

We believe that our tests are the first epigenetics-based clinical tests for heart disease. Unlike genetic biomarkers that are static, the DNA methylation (epigenetic) biomarkers included in our products are generally dynamic. Therefore, DNA methylation biomarkers can change over time and as a result, in addition to initial assessment, our products could potentially be used to personalize interventions and help monitor the effectiveness of these interventions.

Commercial processes that are inherently scalable to meet demand.

Our commercial pipeline is inherently scalable. Laboratory testing kits consist of easy to synthesize oligonucleotide products, readily available PCR reagents, and can be kitted months in advance. Our lancet and vacutainer-based sampling kits incorporate readily available components that can be sourced from several vendors. Our propriety algorithms can be scaled and automated to process data from thousands of samples. In addition, the laboratory processes can be automated and scaled by adding existing commercial equipment.

A leadership team of seasoned healthcare professionals and executives that is led by a visionary founder.

Cardio is led by a management team with experience in inventing innovative technologies, developing and commercializing clinical products, and building high growth companies.

Competition

Even though we believe that our solutions provide significant advantages over solutions that are currently available from other sources, we expect continued intense competition. This includes companies that are entering the cardiovascular diagnostics market or existing companies that are looking to capitalize on the same or similar opportunities as Cardio is in the clinical and non-clinical spaces. Some of our potential and current competitors have longer operating histories and have, or will have, substantially greater financial, technical, research, and other resources than we do, along with larger, more established marketing, sales, distribution, and service organizations. This could enable our competitors to respond more quickly or efficiently than it can to capture a larger market share, respond to changes in the regulatory landscape or adapt to meet new trends in the market. Having access to more resources, these competitors may undertake more extensive research and development efforts, substantially reduce the time to introducing new technologies, accelerate key hires to drive adoption of their technologies, deploy more far-reaching marketing campaigns and implement a more aggressive pricing policy to build larger customer bases than we have. In some cases, we are competing for the same resources our customers allocate for purchasing cardiovascular diagnostics products or for establishing strategic partnerships. We expect new competitors to emerge and the intensity of competition to increase. There is a likelihood that our competitors may develop solutions that are similar ours and ones that could achieve greater market acceptance than ours. This could attract customers away from our solutions and reduce our market share. To compete effectively, we must scale our organization and infrastructure appropriately and demonstrate that our products have superior value propositions, cost savings, and clinical performance.

The clinical cardiovascular diagnostic space is perhaps the most intensely competitive market space in clinical medicine. Even though we believe our solutions offer significant advantages to existing methods, we expect alternative biomarker assessment approaches to continue to exist and to be developed. With respect to coronary heart disease (CHD) risk assessment and early detection, our competitors use a variety of technologies including genetic, serum lipid-based, imaging, proteomic and “people tracking” approaches.

Genetic testing, both whole genome and more focused panel modalities, is the first type of biomarker assessment and is used by many clinicians to assess lifetime risk for CHD. However, whereas the scientific tenets for this approach are generally accepted, it does not identify when CHD might develop, and we believe that the relative power of this method for predicting CHD as compared to its Epi+Gen CHD™ test is limited. In addition, whereas the use of this test may divert revenues for testing, this approach is in some respects complementary, and it is conceivable that some clinicians may elect to get both forms of testing to have a more holistic assessment of both short term and lifetime risk.

The best-known biomarker approach is that embodied by the American Heart Association/American College of Cardiology Atherosclerotic Cardiovascular Risk Calculator (referred to ASCVD risk calculator or Pooled Cohort Equation). This method integrates laboratory assessment of serum lipids, blood pressure and self-reported health variables to impute 10-year risk for all forms of atherosclerotic cardiovascular disease (mainly CHD, but also stroke and peripheral artery disease) using a standard algebraic equation. This is the most commonly used method of assessing CHD risk and enjoys general acceptance by the medical community. It is perhaps the most direct competitor for our Epi+Gen CHD™ test. We believe that our test has superior performance, does not require overnight fasting and will eventually provide greater information to the clinician than this current market standard. In addition, we note that our test assesses risk over a three-year window rather than a 10-year window which it believes is a more relevant period of time for patient management.

Imaging modalities are also used to assess risk for and detect CHD. Perhaps the most commonly used imaging method for predicting risk for CHD is Coronary Artery Calcium (“CAC”) screening. In this method, a low intensity computed tomography (“CT”) scan is taken of the heart. Then using this data, the amount of calcium laden plaque is determined and the result used to assess 10-year risk for CHD. Strengths of this approach include the general acceptance of the medical community. Weaknesses include the necessity of exposing patients to x-ray radiation and the inability of the CAC test to monitor patient response. In many ways, this test competes with our test. At the same time, we note that this test is not yet recommended as a primary method for screening low risk individuals, uses a longer risk assessment window, and could actually be used as secondary testing to evaluate patients who are not found to be at low risk using Epi+Gen CHD™ or who are flagged for CHD by the PrecisionCHD™ test.

Proteomic methods, as exemplified by serologic assessments of individual proteins such as c-reactive protein or of entire protein panels, such as that for the HART CADhs or CVE tests from Prevencio are another risk assessment tool. The CADhs test is a good example of a proteomic competitor and predicts the one-year risk for having ≥70% stenosis in a major coronary artery while another Prevencio test HART CVE, predicts one year risk for individuals at risk for developing a major adverse cardiovascular event. Important differences between our tests and their offerings include the window of prediction (three-year vs one-year), the type of technology employed (AI-guided interpretation of genotype and methylation sensitive digital PCR results compared to algorithm interpretation of results from Luminex bead immunoassays). Because we believe that digital PCR-based methods are more scalable testing solutions than Luminex bead platforms, we believe that our approach has an advantage.

Finally, researchers have described methods to use wearable devices, such as the Huami wrist device, to predict risk for cardiovascular disease. Although people doubtlessly use these and similar methods derived from wearable devices to assess risk, their exact clinical market penetrance is currently low, and whether they would pose as a direct competitor for our test remains uncertain.

However, the aforementioned is only a snapshot of the current market space in which we currently compete and which we intend to compete in the future. Our intellectual property claims include methods to develop tests for coronary heart disease, as well as incident and prevalent heart failure, stroke and diabetes. The test for prevalent coronary heart disease, whose basis was published in 2018, is well underway, and we expect this test to become a strong competitor for other methods of establishing current CHD, such as exercise treadmill testing, and for monitoring response to CHD treatment.

In summary, the cardiovascular diagnostic space is extremely competitive and fast moving. We believe that the serum lipid, proteomic and to a certain extent, imaging-based modalities are direct competitors for customers and enjoy both large existing market share and substantial financial backing. In addition, it is clear that these existing alternative assessment strategies have significant degrees of scientific literature supporting their use, enjoy backing from key medical constituencies for their use in certain circumstances, and have established strategies for obtaining third party reimbursement. As the population ages, this competition is likely to increase. At the same time, we believe that there are important differences between the current tests offered and our solutions with respect to clinical performance, window of clinical assessment, scalability, capacity for assisting with interventions and response monitoring. However, the other technologies are not static, and we expect refinements and/or combination of existing approaches to vigorously compete for customers in our business space. We will need to scale our efforts, orient our organization appropriately and demonstrate that our products provide better value for our customers.

Intellectual Property

We have made broad pending intellectual property (“IP”) claims with respect to the use of epigenetic and gene-methylation interactions for the assessment and monitoring of cardiovascular disease, specifically coronary heart disease, congestive heart failure and stroke, as well as diabetes. Our portfolio falls into seven patent families. The members of these patent families have been filed in the United States and a number of foreign jurisdictions including Europe Union, Japan, India, Australia, United Arab Emirates, Saudi Arabia, Canada and China. U.S., Patent Nos. 11,414,704 and 12,043,869, titled Compositions and Methods for Detecting Predisposition to Cardiovascular Disease, were issued in 2022 and 2024, respectively, to the University of Iowa Research Foundation (“UIRF”), the co-inventors of which are Dr. Dogan and Dr. Philibert, our Chief Executive Officer and Chief Medical Officer, respectively. The original patent family also includes issued patents in Europe, China, Australia, India, and a number of other pending applications. We have a worldwide exclusive license agreement with UIRF. Under UIRF’s Inventions Policy, inventors are generally entitled to 25% of income from earnings from their inventions. Consequently, Dr. Dogan and Dr. Philibert will benefit from this policy.

Our issued and pending patents cover general methods as well as key technological steps that enable these core approaches while facilitating the continued patenting of material included in the patent applications. In addition to the technology licensed from UIRF, we have other patent applications pending relating to improvements to our technology, which are potentially valuable and of possible strategic importance to the Company. We expect to continue to file new patent applications to protect additional products and methodologies as they emerge.

The initial work on our AI-driven Multi-Omics Engine™ is derived from work done by our founders while at the University of Iowa. Follow-on work on our core technology also is derived from work done by our founders while at the University of Iowa but was furthered by our founders and Cardio’s Chief Technology Officer independent of the University of Iowa. The follow-on work is described in our second, third, fourth, fifth and sixth families of patent applications.

The initial work is described in the first family of patents and patent applications and is generally directed to a number of single nucleotide polymorphism (“SNP”) biomarkers and a number of methylation site biomarkers that are associated with the presence or the early onset of a number of cardiovascular diseases. The first family of patents and patent applications is owned solely by UIRF and is exclusively licensed by Cardio. As of March 2025, this family includes thirteen granted patents and seven pending patent applications. Any and all patents issuing in this family will be solely owned by UIRF and, barring any changes to the UIRF exclusive license agreement, will fall under the exclusive license to Cardio.

The first family is generally directed to biomarkers associated with cardiovascular disease. This family includes two issued patents in the US as well as issued patents in the United Kingdom, France, Germany, Italy, Switzerland, Ireland, Hong Kong, Australia, China, Japan, and India, and pending applications in Australia, Canada, China, Europe, Hong Kong, Japan, and the US. The issued claims in the original US patent and in Australia, China and India are directed to methods and/or compositions (e.g., kits) for determining the methylation status of at least one CpG dinucleotide and the genotype of at least one single-nucleotide polymorphism (SNP) that use or include at least one primer for detecting the presence or absence of methylation in a particular region of the genome (referred to as cg12586707) and at least one primer for detecting the presence or absence of a SNP in a particular region of the genome (referred to as rs11597065). The issued claims in the EP patent are similarly directed to compositions (e.g., a kit) for determining the methylation status of at least one CpG dinucleotide and a genotype of at least one SNP that includes at least one primer that detects the presence or absence of methylation in a particular region of the genome (referred to as cg26910465) and at least one primer that detects a SNP in a particular region of the genome (referred to as rs10275666) or another SNP in linkage disequilibrium with the first SNP. The claims that issued in the second U.S. patent are directed to methods for determining the methylation status of at least one CpG dinucleotide and the genotype of at least one SNP that includes at least one primer that detects the presence or absence of methylation in a particular region of the genome (referred to as cg11964099) and at least one primer that detects a SNP in a particular region of the genome (referred to as rs9988960). This family of patents is in-licensed under an exclusive license agreement with UIRF, and is expected to expire in 2037, absent any applicable patent term adjustments or extensions.

The second family is generally directed to biomarkers associated with diabetes. This family includes pending applications in the U.S., Australia, United Arab Emirates, Canada, China, Europe, Hong Kong, India, Japan, and Singapore, with original claims directed to compositions (e.g., a kit) that include at least one primer for determining the methylation status of at least one CpG dinucleotide from a group of five different methylation sites, or a different CpG dinucleotide in linkage disequilibrium with one of the listed CpG dinucleotides, and at least one primer for determining the genotype of at least one SNP from a group of five different SNPs, or a different SNP in linkage disequilibrium with one of the listed SNPs. The pending applications also included original claims to methods of determining the presence of biomarkers associated with diabetes, claims to a computer-readable medium for performing such methods, and claims to a system for determining the methylation status of at least one CpG dinucleotide and the genotype of at least one SNP. This family is co-owned by Cardio Diagnostics and UIRF, and the UIRF-owned portion is in-licensed under the same exclusive license agreement as the first family. Patents issuing from this second family are expected to expire in 2041, absent any applicable patent term adjustments or extensions.

The second family of patent applications is co-owned by UIRF and Cardio, since Cardio expanded on and further refined the original research that was done at the University of Iowa. The ownership of any and all patents that ultimately issue in this family will depend on the specific subject matter that is claimed in each issued patent. For example, depending upon the specific biomarkers claimed and when those biomarkers were identified (e.g., during the initial work at the University of Iowa or during the follow-on work at Cardio), ownership could lie solely with UIRF or Cardio, or ownership could be shared between UIRF and Cardio (e.g., if a claimed biomarker was initially identified at the University of Iowa and its significance with respect to diabetes was further refined by Cardio; or if one of the claimed biomarkers was identified at the University of Iowa and another one of the claimed biomarkers was identified at Cardio).

The third family is generally directed to biomarkers associated with predicting a three-year incidence of cardiovascular disease. This family includes applications pending in the U.S., Australia, United Arab Emirates, Canada, China, Europe, Hong Kong, India, Japan, Saudi Arabia, and Singapore, with original claims directed to compositions (e.g., a kit) that include at least one primer for determining the methylation status of at least one CpG dinucleotide from a group of three different methylation sites, or a different CpG dinucleotide in linkage disequilibrium with one of the listed CpG dinucleotides, and at least one primer for determining the genotype of at least one SNP from a group of five different SNPs, or a different SNP in linkage disequilibrium with one of the listed SNPs. The pending applications also included original claims to methods of determining the presence of biomarkers associated with three-year incidence of cardiovascular disease, claims to a computer-readable medium for performing such methods, and claims to a system for determining the methylation status of at least one CpG dinucleotide and the genotype of a SNP. This family of patents is owned exclusively by Cardio Diagnostics. Patents issuing from this third family are expected to expire in 2041, absent any applicable patent term adjustments or extensions.

The fourth family is generally directed to computer resources (e.g., a dashboard) designed by Cardio Diagnostics for use by their stakeholders (e.g., patients, physicians, researchers, insurance companies, etc.). The computer resources are designed to provide results as well as information and context related to Cardio Diagnostics tests and the specific biomarkers that are used. The pending claims are directed to methods of displaying relevant information including genetic marker test results as well as probability analysis (based on, e.g., the population, age, and/or gender of patients), and hyperlinks to relevant literature. The pending applications also include claims to computer-readable media containing instructions for performing such methods and computer systems for executing such instructions. This family currently includes applications pending in Australia, United Arab Emirates, Canada, China, Europe, India, Japan, Singapore, and the U.S. and is solely owned by Cardio. Patents issuing from this fourth family are expected to expire in 2044, absent any applicable patent term adjustments or extensions.

The fifth family is generally directed to biomarkers associated with detecting cardiovascular disease. The pending claims are directed to compositions (e.g., a kit) that include at least one primer for determining the methylation status of at least one CpG dinucleotide from a group of six different methylation sites, or a different CpG dinucleotide in linkage disequilibrium with one of the listed CpG dinucleotides, and at least one primer for determining the genotype of at least one SNP from a group of ten different SNPs, or a different SNP in linkage disequilibrium with one of the listed SNPs. The pending application also includes claims to methods of determining the presence of biomarkers associated with detecting cardiovascular disease, claims to a computer- readable medium for performing such methods, and claims to a system for determining the methylation status of at least one CpG dinucleotide and the genotype of a SNP. This family currently includes applications, pending in Australia, United Arab Emirates, Canada, China, Europe, India, Japan, Saudi Arabia, Singapore, and the U.S. and is solely owned by Cardio. Patents issuing from this fifth family are expected to expire in 2044, absent any applicable patent term adjustments or extensions.

The sixth family is generally directed to an algorithm that can be used to predict mortality based on the methylation status of at least one CpG dinucleotide and/or information obtained from cardio-imaging. The pending claims are directed to methods for predicting mortality based on the presence of cardiovascular disease that include obtaining epigenetic data and/or image data and generating an output that includes a mortality risk assessment for the subject. This family currently includes an International PCT application, which is owned solely by Cardio. Patents issuing from the sixth family are expected to expire in 2045, absent any applicable patent term adjustments or extensions.

The seventh family is generally directed to using methylation sites and levels to predict the level of coronary artery obstruction and ischemia in those with acute coronary syndrome. This family currently includes a pending U.S. provisional application, which is owned solely by Cardio. Patents issuing from the seventh family are expected to expire in 2046, absent any applicable patent term adjustments or extensions.

The Exclusive License Agreement entered into with UIRF and those licenses granted under that license agreement terminate on the expiration of the patent rights licensed under the license agreement, unless certain proprietary, non-patented technical information is still being used by Cardio, in which case the license agreement will not terminate until the date of termination of such use. The licenses under the license agreement could terminate prior to the expiration of the licensed patent rights if we materially breach our obligations under the license agreement, including failing to pay the applicable license fees and any interest on such fees, and failing to fully remedy such breach within the period specified in the license agreement, or if we enter liquidation, have a receiver or administrator appointed over any assets related to the license agreement, or if we cease to carry on business, file for bankruptcy or if an involuntary bankruptcy petition is filed against Cardio.

Additionally, we have considerable IP in the form of trade secrets, including bioinformatics and high-performance computing techniques and artificial intelligence and machine learning algorithms used to identify genetic and epigenetic biomarkers for various products and to interpret genetic and epigenetic data from patient samples to generate clinically actionable information, as well as the methods to develop new methylation sensitive assays. We protect our proprietary information, which includes, but is not limited to, trade secrets, know-how, and copyrights. Our future success depends on protecting that knowledge, obtaining trademarks on our products, copyright on key materials, and avoiding infringing on the IP rights of others. Where appropriate, we will assess the operating space and acquire licenses for critical technologies that we do not possess or cannot create. We continue to invest in technological innovation and will seek mutualistic and symbiotic licensing opportunities to promote and maintain our competitive position.

In order to provide our products, we currently use a variety of third party technologies including, for example, genotyping, digital methylation assessment and data processing technologies. The terms of these agreements for the non-exclusive use of these technologies are subject to change without notice and could affect our ability to deliver our solutions. In addition, from time to time, we may face claims from third parties asserting ownership of, or demanding release of, the open-source software or derivative works that we developed using such software (which could include our proprietary source code), or otherwise seeking to enforce the terms of the applicable open-source license. These claims could result in litigation that could be costly to defend, have a negative effect on our operating results and financial condition or require us to devote additional research and development resources to change our existing or future solutions. Responding to any infringement or noncompliance claim by an open-source vendor, regardless of its validity, discovering certain open-source software code in our products, or a finding that we have breached the terms of an open-source software license, could harm our business, results of operations and financial condition. In each case, we would be required to either seek licenses to software or services from other parties and redesign our products to function with such other parties’ software or services or develop these components internally, which would result in increased costs and could result in delays to product launches. Furthermore, we might be forced to limit the features available in our current or future solutions.

Government Regulation

The laboratory testing and healthcare industry and the practice of medicine are extensively regulated at both the state and federal levels, and additionally, the practice of medicine is similarly extensively regulated by the various states. Our ability to operate profitably will depend in part upon its ability, and that of its vendor partners, to maintain all necessary licenses and to operate in compliance with applicable laws and rules. Those laws and rules continue to evolve, and therefore we devote significant resources to monitoring relevant developments in FDA, CLIA, healthcare and medical practice regulation. Those laws and rules include, but are not limited to, ones that govern the regulation of clinical laboratories in general and the regulation of LDTs in particular. As discussed below, legislation has been introduced in Congress that, if enacted, would substantially alter federal regulation of diagnostic tests, including LDTs. As the applicable laws and rules change, we are likely to make conforming modifications in our business processes from time to time. In many jurisdictions where we operate, neither our current nor our anticipated business model has been the subject of judicial or administrative interpretation. We cannot be assured that a review of our business by courts or regulatory authorities will not result in determinations that could adversely affect our operations or that the laboratory and healthcare regulatory environment will not change in a way that restricts our operations.

State and Federal Regulatory Issues

Clinical Laboratory Improvement Amendments of 1988 and State Regulation

Clinical laboratories are required to hold certain federal and state licenses, certifications and permits to conduct our business. As to federal certifications, in 1988, Congress passed the Clinical Laboratory Improvement Amendments of 1988, or (“CLIA”), establishing more rigorous quality standards for all commercial laboratories that perform testing on human specimens for the purpose of providing information for the diagnosis, prevention, or treatment of disease or the assessment of the health of human beings. CLIA requires such laboratories to be certified by the federal government and mandates compliance with various operational, personnel, facilities administration, validation, quality and proficiency testing requirements intended to ensure the accuracy, reliability and timeliness of patient test results. CLIA certification is also a prerequisite to be eligible to bill state and federal healthcare programs, as well as many commercial third- party payers, for laboratory testing services. The Centers for Medicare & Medicaid Services (“CMS”) regulates laboratories that perform testing on individuals in the U.S. through CLIA.

Laboratories must comply with all applicable CLIA requirements. If a clinical laboratory is found not to comply with CLIA standards, the government may impose sanctions, limit or revoke the laboratory’s CLIA certificate (and prohibit the owner, operator or laboratory director from owning, operating, or directing a laboratory for two years following license revocation), subject the laboratory to a directed plan of correction, on-site monitoring, civil monetary penalties, civil actions for injunctive relief, criminal penalties, or suspension or exclusion from the Medicare and Medicaid programs.

CLIA provides that a state may adopt laboratory licensure requirements and regulations that are more stringent than those under federal law and requires compliance with such laws and regulations. New York State in particular, has implemented its own more stringent laboratory regulatory requirements. State laws may require the laboratory to obtain state licensure and/or laboratory personnel to meet certain qualifications, specify certain quality control procedures or facility requirements, or prescribe record maintenance requirements. Moreover, several states impose the same or similar state requirements on out-of-state laboratory testing specimens collected or received from, or test results reported back to, residents within that state. Therefore, the laboratory is required to meet certain laboratory licensing requirements for those states in which we offer services or from which we accept specimens and that have adopted regulations beyond CLIA. For more information on state licensing requirements, see “California Laboratory Licensing,” “New York Laboratory Licensing” and “Other State Laboratory Licensing Laws.”

California Laboratory Licensing

In addition to federal certification requirements for laboratories under CLIA, the laboratory is required under California law to maintain a California state license and comply with California state laboratory laws and regulations. Similar to the federal CLIA regulations, the California state laboratory laws and regulations establish standards for the operation of a clinical laboratory and performance of test services, including the education and experience requirements of the laboratory director and personnel (including requirements for documentation of competency), equipment validations, and quality Management practices. All testing personnel must maintain a California state license or be supervised by licensed personnel.

Clinical laboratories are subject to both routine and complaint-initiated on-site inspections by the state. If a clinical laboratory is found to be out of compliance with California laboratory standards, the California Department of Public Health (“CDPH”) may suspend, restrict or revoke the California state laboratory license to operate the clinical laboratory (and exclude persons or entities from owning, operating, or directing a laboratory for two years following license revocation), assess civil money penalties, and/or impose specific corrective action plans, among other sanctions. Clinical laboratories must also provide notice to CDPH of any changes in the ownership, directorship, name or location of the laboratory. Failure to provide such notification may result in revocation of the state license and sanctions under the CLIA program. Any revocation of a CLIA certificate or exclusion from participation in Medicare or Medicaid programs may result in suspension of the California state laboratory license.

New York Laboratory Licensing

We currently do not conduct tests on specimens originating from New York State. In order to test specimens originating from, and return results to New York State, a clinical laboratory is required to obtain a New York state laboratory permit and comply with New York state laboratory laws and regulations. The New York state laboratory laws, regulations and rules are equal to or more stringent than the CLIA regulations and establish standards for the operation of a clinical laboratory and performance of test services, including education and experience requirements of a laboratory director and personnel, physical requirements of a laboratory facility, equipment validations, and quality Management practices. The laboratory director(s) must maintain a Certificate of Qualification issued by the New York State Department of Health (“NYS DOH”) in the permitted test categories.

A clinical laboratory conducting tests on specimens originating in New York is subject to proficiency testing and on-site survey inspections conducted by the Clinical Laboratory Evaluation Program (“CLEP”) under the NYS DOH. If a laboratory is found to be out of compliance with New York’s CLEP standards, the NYS DOH, may suspend, limit, revoke or annul the New York laboratory permit, censure the holder of the license or assess civil money penalties. Statutory or regulatory noncompliance may result in a laboratory’s operator, owners and/or laboratory director being found guilty of a misdemeanor under New York law. Clinical laboratories must also provide notice to CLEP of any changes in ownership, directorship, name or location of the laboratory. Failure to provide such notification may result in revocation of the state license and sanctions under the CLIA program. Any revocation of a CLIA certificate or exclusion from participation in the Medicare or Medicaid programs may result in suspension of the New York laboratory permit.

The NYS DOH also must approve each LDT before that test is offered to patients located in New York.

Other State Laboratory Licensing Laws

In addition to New York and California, certain other states require licensing of out-of-state laboratories under certain circumstances. We have obtained or are in the process of obtaining licenses in the states that we believe require us to do so, including Maryland, Pennsylvania and Rhode Island, and believe we are in compliance with applicable state laboratory licensing laws.

Potential sanctions for violation of state statutes and regulations can include significant monetary fines, the rejection of license applications, the suspension or loss of various licenses, certificates and authorizations, and in some cases criminal penalties, which could harm our business. CLIA does not preempt state laws that have established laboratory quality standards that are more stringent than federal law.

Laboratory-Developed Tests

The FDA generally considers an LDT to be a test that is designed, manufactured, and used within a single laboratory that is certified under CLIA and meets the regulatory requirements under CLIA to perform high complexity testing. LDTs are performed using a variety of laboratory instruments and reagents and may also incorporate FDA-authorized in vitro diagnostics (“IVDs”) that the laboratory modifies in some way and validates for its new use. The FDA historically took the position that it had the authority to regulate LDTs as medical devices under the Federal Food, Drug, and Cosmetic Act (“FDC Act”) but generally exercised enforcement discretion with regard to LDTs. This meant that even though the FDA believed it could impose regulatory requirements on LDTs, such as requirements to obtain premarket approval, de novo authorization, or 510(k) clearance of LDTs, it generally chose not to enforce those requirements.

On May 6, 2024, FDA published a final rule amending the definition of an in vitro diagnostic (“IVD”) device to include tests manufactured by a clinical laboratory. Pursuant to the rule, LDTs would have been subject to regulation as medical devices under the FDC Act, including, unless exempt, premarket authorization requirements (510(k), de novo classification, or PMA) for each LDT performed by the laboratory, and to postmarket registration and listing, medical device reporting, correction, removal, and recall, complaint handling, labeling, investigational device, and quality system requirements.

On March 31, 2025, a federal district court vacated the FDA final rule, thereby cancelling the rulemaking’s associated requirements. The court held that LDTs do not meet the definition of a medical device under the FDC Act and the FDA therefore lacks jurisdiction to regulate them. The court directed FDA to rescind the final rule, which occurred on September 19, 2025. The FDA has not indicated how it will interpret the court ruling or whether it will seek a different regulatory approach with respect to LDTs or components thereof.

Over the years, various legislative proposals addressing the FDA’s oversight of LDTs have been introduced in Congress. In June 2021, Congress introduced the Verifying Accurate, Leading-edge IVCT Development Act (“VALID Act”) to establish a new risk-based regulatory framework for in vitro clinical tests (“IVCTs”), including IVDs, LDTs, collection devices and instruments used with such tests. This legislation was re-introduced in 2023 but was not enacted. The VALID Act was again re-introduced in 2025, indicating that there remains debate about whether and how LDTs should be regulated in the U.S.

This legislation was re-introduced in 2023 but was not enacted. The VALID Act was again re-introduced in 2025, indicating that there remains debate about whether and how LDTs should be regulated in the U.S.

As mentioned above, separately, CMS oversees clinical laboratory operations through the CLIA program

Regulation of Medical Devices by the U.S. Food and Drug Administration

To be commercially distributed in the United States, medical devices, including some collection devices used to collect samples for testing, and certain types of software, must receive from the FDA prior to marketing, unless subject to an exemption, clearance of a premarket notification (“510(k) clearance”), premarket approval (“PMA”), or a de novo authorization.

IVDs are a type of medical device that are intended to be used in the diagnosis or detection of diseases or conditions, including a determination of the state of health, through collection, preparation and examination of specimens taken from the human body. IVDs may be used to detect the presence of certain chemicals, genetic information or other biomarkers related to diagnosis or detection of diseases or conditions. IVDs may include tests for disease prediction, prognosis, diagnosis, and screening.

The FDC Act classifies medical devices into one of three categories based on the risks associated with the device and the level of control necessary to provide reasonable assurance of safety and effectiveness. Class I devices are deemed to be low risk and are subject to the fewest regulatory controls. Many Class I devices are exempt from FDA premarket review requirements. Class II devices, including some software products to the extent that they qualify as a device, are deemed to be moderate risk, and generally require clearance through the premarket notification, or 510(k) clearance, process. Class III devices are generally the highest risk devices and are subject to the highest level of regulatory control to provide reasonable assurance of the device's safety and effectiveness. Class III devices typically require a PMA by the FDA before they are marketed. A clinical trial is almost always required to support a PMA application or de novo authorization and is sometimes required for 510(k) clearance. All clinical studies of investigational devices must be conducted in compliance with any applicable FDA and Institutional Review Board requirements. Devices that are exempt from FDA premarket review requirements must nonetheless comply with post-market general controls as described below, unless the FDA has indicated otherwise.

510(k) clearance pathway. To obtain 510(k) clearance, a manufacturer must submit a premarket notification demonstrating to the FDA’s satisfaction that the new device is substantially equivalent to a “predicate device.” A predicate device is a legally marketed device to which a new device may be compared to for a determination regarding substantial equivalence. A legally marketed device is a device that was previously 510(k)-cleared, a device that received de novo authorization, or a device that was in commercial distribution before May 28, 1976 for which the FDA has not called for submission of a PMA application. The FDA’s 510(k) clearance pathway usually takes from three to 12 months from submission, but it can take longer, particularly for a novel type of product.

PMA pathway. The PMA pathway requires proof of the safety and effectiveness of the device to the FDA’s satisfaction. The PMA pathway is costly, lengthy, and uncertain. A PMA application must provide extensive preclinical and clinical trial data as well as information about the device and its components regarding, among other things, device design, manufacturing, and labeling. As part of its PMA review process, the FDA will typically inspect the manufacturer’s facilities for compliance with the Quality Management System Regulation (“QMSR”) requirements, which impose extensive testing, control, documentation, and other quality assurance procedures. The PMA review process typically takes one to three years from submission but can take longer.

De novo pathway. If no predicate device can be identified, a device is automatically classified as Class III, requiring a PMA application. However, the FDA can reclassify, either on its own initiative or in response to a request for de novo classification, for a device for which there was no predicate device if the device is low- or moderate-risk. If the device is reclassified as Class II, the FDA will identify special controls that the manufacturer must implement, which may include labeling, testing, performance standards, or other requirements. Subsequent applicants can rely upon the de novo device as a predicate for a 510(k) clearance, unless the FDA exempts subsequent devices from the need for a 510(k). The de novo route is intended to be less burdensome than the PMA process.

Post-market general controls. After a device, including a device exempt from FDA premarket review, is placed on the market, numerous regulatory requirements apply. These include: the QMSR, labeling regulations, registration and listing, the Medical Device Reporting regulation (which requires that manufacturers report to the FDA if their device may have caused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur), and the Reports of Corrections and Removals regulation (which requires manufacturers to report to the FDA corrective actions made to, or removal of, products in the field, if such actions were initiated to reduce a risk to health posed by the device or to remedy a violation of the FDC Act which may present a health risk). Depending on the severity of the legal violation that led to correction or removal, the FDA may classify the manufacturer’s action as a recall.

The FDA enforces compliance with its requirements through inspection and market surveillance. If the FDA finds a violation, it can institute a wide variety of actions, ranging from an untitled or warning letter sent to manufacturers to enforcement actions such as fines, injunctions, and civil penalties; recall or seizure of products; operating restrictions, partial suspension or total shutdown of production; refusing requests for 510(k) clearance or PMA approval of new products; withdrawal of PMAs already granted; and criminal prosecution.

Software

Software that is intended for use in diagnosis, treatment, cure mitigation or prevention of disease meets the definition of a medical device and is subject to FDA regulation. Software that is included in a hardware device (Software as a Medical Device or “SiMD”) is regulated as part of the hardware device. Freestanding software (Software as a Medical Device or “SaMD”) may be subject to regulation by FDA but may be exempt from regulation if it meets certain criteria.

The FDA has become increasingly active in addressing the regulation of software used to support clinical decision making. In 2016, the 21st Century Cures Act, (the “Cures Act”), among other things, amended the medical device definition in the FDC Act to exclude certain software from FDA regulation, including clinical decision support (“CDS software”) that meets certain criteria. CDS software is exempt from the medical device definition if it: (a) displays, analyzes or prints medical information about a patient or other medical information; (b) is intended for the purpose of supporting or providing recommendations about a patient’s care to a health care professional, (“HCP”), user; and (c) provides sufficient information about the basis for the recommendations to the HCP user, so that the HCP user does not rely primarily on any of the recommendations to make a clinical decision about an individual patient; unless (d) the software function acquires, processes, or analyzes a medical image, a signal from an in vitro diagnostic device, or a pattern or signal from a signal acquisition system.

FDA issued a final guidance document addressing CDS software on September 28, 2022, and issued a revised guidance document on January 29, 2026. Among other views expressed, the final guidance stated that software functions that assess or interpret the clinical implications or clinical relevance of a signal or pattern, such as those that process or analyze an electrochemical or photometric response generated by an assay and instrument to generate a clinical test result, are not exempt from medical device regulation.

Corporate Practice of Medicine; Fee-Splitting

We contract with various healthcare companies to deliver services to patients. This contractual relationship is subject to various state laws, including those of New York, Texas and California, that prohibit fee-splitting or the practice of medicine by lay entities or persons and are intended to prevent unlicensed persons from interfering with or influencing the physician’s professional judgment. In addition, various state laws also generally prohibit the sharing of professional services income with nonprofessional or business interests. Activities other than those directly related to the delivery of healthcare may be considered an element of the practice of medicine in many states. Under the corporate practice of medicine restrictions of certain states, decisions and activities such as scheduling, contracting, setting rates and the hiring and management of non-clinical personnel may implicate the restrictions on the corporate practice of medicine.

State corporate practice of medicine and fee-splitting laws vary from state to state and are not always consistent among states. In addition, these requirements are subject to broad powers of interpretation and enforcement by state regulators. Some of these requirements may apply to any telemedicine company or provider organization we contract with. Failure to comply with regulations could lead to adverse judicial or administrative action against us and/or the providers we work with, civil or criminal penalties, receipt of cease-and-desist orders from state regulators, loss of provider licenses, the need to make changes to the terms of engagement with any telemedicine company or provider organization we contract with that interfere with our business and other materially adverse consequences.

Federal and State Fraud and Abuse Laws

Healthcare Laws Generally

The federal Health Insurance Portability and Accountability Act of 1996, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and their implementing regulations, which is collectively referred to as HIPAA, established several separate criminal penalties for making false or fraudulent claims to insurance companies and other non- governmental payors of healthcare services. Under HIPAA, these two additional federal crimes are: "Healthcare Fraud” and "False Statements Relating to Healthcare Matters.” The Healthcare Fraud statute prohibits knowingly and recklessly executing a scheme or artifice to defraud any healthcare benefit program, including private payors. A violation of this statute is a felony and may result in fines, imprisonment or exclusion from government-sponsored programs. The False Statements Relating to Healthcare Matters statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact by any trick, scheme or device or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. A violation of this statute is a felony and may result in fines or imprisonment. This statute could be used by the government to assert criminal liability if a healthcare provider knowingly fails to refund an overpayment. These provisions are intended to punish some of the same conduct in the submission of claims to private payors as the federal False Claims Act covers in connection with governmental health programs.

In addition, the Civil Monetary Penalties Law imposes civil administrative sanctions for, among other violations, inappropriate billing of services to federally funded healthcare programs and employing or contracting with individuals or entities who are excluded from participation in federally funded healthcare programs. Moreover, a person who offers or transfers to a Medicare or Medicaid beneficiary any remuneration, including waivers of co-payments and deductible amounts (or any part thereof), that the person knows or should know is likely to influence the beneficiary’s selection of a particular provider, practitioner or supplier of Medicare or Medicaid payable items or services may be liable for civil monetary penalties of up to $10,000 for each wrongful act. Moreover, in certain cases, providers who routinely waive copayments and deductibles for Medicare and Medicaid beneficiaries can also be held liable under the Anti-Kickback Statute and civil False Claims Act, which can impose additional penalties associated with the wrongful act. One of the statutory exceptions to the prohibition is non-routine, unadvertised waivers of copayments or deductible amounts based on individualized determinations of financial need or exhaustion of reasonable collection efforts. The OIG emphasizes, however, that this exception should only be used occasionally to address special financial needs of a particular patient. Although this prohibition applies only to federal healthcare program beneficiaries, the routine waivers of copayments and deductibles offered to patients covered by commercial payers may implicate applicable state laws related to, among other things, unlawful schemes to defraud, excessive fees for services, tortious interference with patient contracts and statutory or common law fraud.

Federal Stark Law

We are subject to the federal self-referral prohibitions, commonly known as the Stark Law. Where applicable, this law prohibits a physician from referring Medicare patients to an entity providing "designated health services” if the physician or a member of such physician’s immediate family has a "financial relationship” with the entity, unless an exception applies. The penalties for violating the Stark Law include the denial of payment for services ordered in violation of the statute, mandatory refunds of any sums paid for such services, civil penalties of up to $15,000 for each violation and twice the dollar value of each such service and possible exclusion from future participation in the federally-funded healthcare programs. A person who engages in a scheme to circumvent the Stark Law’s prohibitions may be fined up to $100,000 for each applicable arrangement or scheme. The Stark Law is a strict liability statute, which means proof of specific intent to violate the law is not required. In addition, the government and some courts have taken the position that claims presented in violation of the various statutes, including the Stark Law can be considered a violation of the federal False Claims Act (described below) based on the contention that a provider impliedly certifies compliance with all applicable laws, regulations and other rules when submitting claims for reimbursement. A determination of liability under the Stark Law could have a material adverse effect on our business, financial condition and results of operations.

Federal Anti-Kickback Statute

We are also subject to the federal Anti-Kickback Statute. The Anti-Kickback Statute is broadly worded and prohibits the knowing and willful offer, payment, solicitation or receipt of any form of remuneration in return for, or to induce, (i) the referral of a person covered by Medicare, Medicaid or other governmental programs, (ii) the furnishing or arranging for the furnishing of items or services reimbursable under Medicare, Medicaid or other governmental programs or (iii) the purchasing, leasing or ordering or arranging or recommending purchasing, leasing or ordering of any item or service reimbursable under Medicare, Medicaid or other governmental programs. Certain federal courts have held that the Anti-Kickback Statute can be violated if "one purpose” of a payment is to induce referrals. In addition, a person or entity does not need to have actual knowledge of this statute or specific intent to violate it to have committed a violation, making it easier for the government to prove that a defendant had the requisite state of mind or "scienter” required for a violation. Moreover, the government may assert that a claim including items or services resulting from a violation of the Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act, as discussed below. Violations of the Anti- Kickback Statute can result in exclusion from Medicare, Medicaid or other governmental programs as well as civil and criminal penalties, including fines of $50,000 per violation and three times the amount of the unlawful remuneration. Imposition of any of these remedies could have a material adverse effect on our business, financial condition and results of operations. In addition to a few statutory exceptions, the U.S. Department of Health and Human Services Office of Inspector General, or OIG, has published safe-harbor regulations that outline categories of activities that are deemed protected from prosecution under the Anti-Kickback Statute provided all applicable criteria are met. The failure of a financial relationship to meet all of the applicable safe harbor criteria does not necessarily mean that the particular arrangement violates the Anti-Kickback Statute. However, conduct and business arrangements that do not fully satisfy each applicable safe harbor may result in increased scrutiny by government enforcement authorities, such as the OIG.

False Claims Act

Both federal and state government agencies have continued civil and criminal enforcement efforts as part of numerous ongoing investigations of healthcare companies and their executives and managers. Although there are a number of civil and criminal statutes that can be applied to healthcare providers, a significant number of these investigations involve the federal False Claims Act. These investigations can be initiated not only by the government but also by a private party asserting direct knowledge of fraud. These "qui tam” whistleblower lawsuits may be initiated against any person or entity alleging such person or entity has knowingly or recklessly presented, or caused to be presented, a false or fraudulent request for payment from the federal government or has made a false statement or used a false record to get a claim approved. In addition, the improper retention of an overpayment for 60 days or more is also a basis for a False Claim Act action, even if the claim was originally submitted appropriately. Penalties for False Claims Act violations include fines ranging from $5,500 to $11,000 for each false claim, plus up to three times the amount of damages sustained by the federal government. A False Claims Act violation may provide the basis for exclusion from the federally-funded healthcare programs. In addition, some states have adopted similar fraud, whistleblower and false claims provisions.

State Fraud and Abuse Laws

Several states in which we operate have also adopted similar fraud and abuse laws as described above. The scope of these laws and the interpretations of them vary from state to state and are enforced by state courts and regulatory authorities, each with broad discretion. Some state fraud and abuse laws apply to items or services reimbursed by any third-party payor, including commercial insurers, not just those reimbursed by a federally-funded healthcare program. A determination of liability under such state fraud and abuse laws could result in fines and penalties and restrictions on our ability to operate in these jurisdictions.

State and Federal Health Information Privacy and Security Laws

There are numerous U.S. federal and state laws and regulations related to the privacy and security of personally identifiable information, or PII, including health information. In particular, HIPAA establishes privacy and security standards that limit the use and disclosure of protected health information, or PHI, and require the implementation of administrative, physical, and technical safeguards to ensure the confidentiality, integrity and availability of individually identifiable health information in electronic form. Since the effective date of the HIPAA Omnibus Final Rule on September 23, 2013, HIPAA’s requirements are also directly applicable to the independent contractors, agents and other "business associates” of covered entities that create, receive, maintain or transmit PHI in connection with providing services to covered entities. Although Cardio is a covered entity under HIPAA, Cardio is also a business associate of other covered entities when Cardio is working on behalf of our affiliated medical groups.

Violations of HIPAA may result in civil and criminal penalties. The civil penalties range from $100 to $50,000 per violation, with a cap of $1.5 million per year for violations of the same standard during the same calendar year. However, a single breach incident can result in violations of multiple standards. Cardio must also comply with HIPAA’s breach notification rule. Under the breach notification rule, covered entities must notify affected individuals without unreasonable delay in the case of a breach of unsecured PHI, which may compromise the privacy, security or integrity of the PHI. In addition, notification must be provided to the HHS and the local media in cases where a breach affects more than 500 individuals. Breaches affecting fewer than 500 individuals must be reported to HHS on an annual basis. The regulations also require business associates of covered entities to notify the covered entity of breaches by the business associate.

State attorneys general also have the right to prosecute HIPAA violations committed against residents of their states. While HIPAA does not create a private right of action that would allow individuals to sue in civil court for a HIPAA violation, its standards have been used as the basis for the duty of care in state civil suits, such as those for negligence or recklessness in misusing personal information. In addition, HIPAA mandates that HHS conduct periodic compliance audits of HIPAA covered entities and their business associates for compliance. It also tasks HHS with establishing a methodology whereby harmed individuals who were the victims of breaches of unsecured PHI may receive a percentage of the Civil Monetary Penalty fine paid by the violator. In light of the HIPAA Omnibus Final Rule, recent enforcement activity, and statements from HHS, we expect increased federal and state HIPAA privacy and security enforcement efforts.

HIPAA also required HHS to adopt national standards establishing electronic transaction standards that all healthcare providers must use when submitting or receiving certain healthcare transactions electronically. On January 16, 2009, HHS released the final rule mandating that everyone covered by HIPAA must implement ICD-10 for medical coding on October 1, 2013, which was subsequently extended to October 1, 2015 and is now in effect.

Many states in which we operate and in which patients reside also have laws that protect the privacy and security of sensitive and personal information, including health information. These laws may be similar to or even more protective than HIPAA and other federal privacy laws. For example, the laws of the State of California, in which we operate, are more restrictive than HIPAA. Where state laws are more protective than HIPAA, we must comply with the state laws we are subject to, in addition to HIPAA. In certain cases, it may be necessary to modify our planned operations and procedures to comply with these more stringent state laws. Not only may some of these state laws impose fines and penalties upon violators, but also some, unlike HIPAA, may afford private rights of action to individuals who believe their personal information has been misused. In addition, state laws are changing rapidly, and there is discussion of a new federal privacy law or federal breach notification law, to which we may be subject.

In addition to HIPAA, state health information privacy and state health information privacy laws, we may be subject to other state and federal privacy laws, including laws that prohibit unfair privacy and security practices and deceptive statements about privacy and security and laws that place specific requirements on certain types of activities, such as data security and texting.

In recent years, there have been a number of well-publicized data breaches involving the improper use and disclosure of PII and PHI. Many states have responded to these incidents by enacting laws requiring holders of personal information to maintain safeguards and to take certain actions in response to a data breach, such as providing prompt notification of the breach to affected individuals and state officials. In addition, under HIPAA and pursuant to the related contracts that we enter into with our business associates, we must report breaches of unsecured PHI to our contractual partners following discovery of the breach. Notification must also be made in certain circumstances to affected individuals, federal authorities and others.

State Privacy Laws

Various states have enacted laws governing the privacy of personal information collected and used by businesses online. For example, California adopted the California Consumer Privacy Act of 2018 ("CCPA”), which went into effect on January 1, 2020 and was recently amended by the California Privacy Rights Act of 2020 which significantly modified the CCPA in ways that affect businesses. This law, in part, requires that companies make certain disclosures to consumers via their privacy policies, or otherwise at the time the personal data is collected. We will have to determine what personal data it is collecting from individuals and for what purposes, and to update its privacy policy every 12 months to make the required disclosures, among other things.

Employees and Human Capital Resources

As of March 13, 2026, we had 15 full-time employees and two part-time employees. Three of our employees hold Ph.D. or M.D. degrees. We also engage contractors and consultants from time to time. None of our employees are represented by a labor union or covered under a collective bargaining agreement.

Our human capital resources objectives include, identifying, recruiting, retaining, incentivizing and integrating our existing and additional employees into our collaborative culture. Our compensation program is designed to retain, motivate and attract highly qualified executives and talented employees and consultants. We are committed to fostering a culture that supports diversity and an environment of mutual respect, equity and collaboration that helps drive our business and our mission to become one of the leading medical technology companies for enabling improved prevention, detection, treatment and management of cardiovascular disease.

Emerging Growth Company, Smaller Reporting Company and Non-Accelerated Filer Status

We are an emerging growth company (“EGC”), as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not EGCs, including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as amended (the “Sarbanes-Oxley Act”), reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts EGCs from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a registration statement under the Securities Act declared effective or do not have a class of securities registered under the Securities Exchange Act of 1934, as amended the “Exchange Act”), are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. We have elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an EGC, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of our financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Additionally, we are a “smaller reporting company” as defined in Item 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements, as well as continued reduced executive compensation disclosure. We will remain a smaller reporting company until the last day of the fiscal year in which (1) the market value of our Common Stock held by non-affiliates equaled or exceeded $250 million as of the end of the prior June 30th, or (2) our annual revenues equaled or exceeded $100 million during such completed fiscal year and the market value of our Common Stock held by non-affiliates equaled or exceeded $700 million as of the prior June 30th.

We will remain an emerging growth company until December 31, 2026, after which we will be subject to certain requirements from which we have previously been exempt. However, we will continue to be a smaller reporting company, as well as a non-accelerated filer. As a result of losing EGC status, beginning in 2027, we will no longer be able to take advantage of the extended transition period for new or revised accounting standards, and instead, will need to adopt any new standards according to the timelines applicable to non- EGCs. We also will be required to hold nonbinding stockholder advisory votes on executive compensation and seek stockholder approval of any golden parachute payments not previously approved. However, as a smaller reporting company, we will be allowed to continue including only two years of audited financial statements in our securities filings and can elect to continue providing scaled down executive compensation disclosure. Most significantly in terms of expenditure of resources, because we will continue to be both a smaller reporting company and a non-accelerated filer, we will continue to be exempt from the requirement to obtain an auditor’s attestation on management’s assessment of the effectiveness of our internal control over financial reporting. We expect that we will continue to take advantage of the smaller reporting company and non-accelerated filer benefits for the foreseeable future.

Item 1A. Risk Factors

RISK FACTORS

Investing in our securities involves risks. You should carefully consider the risks and uncertainties described below and the other information in this Annual Report on Form 10-K before making an investment in our Common Stock. Our business, financial condition, results of operations, or prospects could be materially and adversely affected if any of these risks occurs, and as a result, the market price of our Common Stock could decline and you could lose all or part of your investment. This Annual Report on Form 10-K also contains forward-looking statements that involve risks and uncertainties. See “Cautionary Statement Regarding Forward-Looking Statements.” Our actual results could differ materially and adversely from those anticipated in these forward-looking statements as a result of certain factors, including those set forth below. These disclosures reflect the Company’s beliefs and opinions as to factors that could materially and adversely affect the Company and its securities in the future. References to past events are provided by way of example only and are not intended to be a complete listing or a representation as to whether or not such factors have occurred in the past or their likelihood of occurring in the future.

Risks Related to Our Limited Operating History and Early Stage of Growth

We are a medical diagnostic testing company with a limited operating history and have not yet generated significant revenue from product sales. We have incurred operating losses since our inception and may never achieve or maintain profitability.

We have generated only nominal revenue in 2024 and 2025, including $34,890 in revenue generated in 2024 and $14,825 in revenue generated in 2025. Our net losses totaled $8,383,453 and $6,498,167 for the years ended December 31, 2024 and 2025, respectively, and we have an accumulated deficit of $29,250,000 at December 31, 2025. We expect losses to continue as a result of our ongoing activities to increase the adoption of our products, to gain market recognition and acceptance of our products, to expand our marketing channels and otherwise position ourselves to grow our revenue opportunities, all of which will require hiring additional employees as well as other significant expenses. We are unable to predict when we will become profitable, and it is possible that we may never become profitable. We may encounter unforeseen expenses, difficulties, complications, delays, and other unknown factors that may adversely affect our business. The size of our future net losses will depend, in part, on the rate of future growth of our expenses, which we expect to increase substantially as a public company, and on our ability to generate revenue. Even if we achieve profitability in the future, we may not be able to sustain profitability in subsequent periods. If additional capital is not available when required, if at all, or is not available on acceptable terms, we could be forced to modify or abandon our current business plan.

The healthcare commercialization process is inherently lengthy and subject to regulatory, reimbursement, evidentiary and behavioral factors, which, combined with clinical adoption of novel diagnostic technologies that frequently spans multiple years, results in a lengthy period from initial development to widespread utilization and ultimately to revenue generation, which, in some cases, may span a decade or more.

The commercialization lifecycle for diagnostic tests is lengthy and generally involves multiple stages, including scientific validation, regulatory compliance, the securing of third-party reimbursement, including coverage determination from government programs including the Centers for Medicare & Medicaid Services (“CMS”) and subsequently, from commercial payors, physician adoption and incorporation into clinical guidelines and behavioral and workflow integration as health care providers gain familiarity and comfort with new technologies. These various stages can each take many years, and the entire process from scientific discovery to broad clinical adoption frequently can extend over a decade. Despite having two clinically promising diagnostic tests currently available and more tests in the pipeline, we expect that our revenue growth will continue to be negligible until we have obtained third party reimbursement for our tests, the tests are incorporated into the broader health care clinical guidelines and are integrated into medical care workflow by health care providers. There is no assurance that we will be successful in achieving those milestones and begin growing meaningful revenue. We also cannot provide assurance that we will ever achieve profitability even as we grow revenue.

We believe our long-term value as a company will be greater if we focus on growth, which has in the past, and may continue to negatively impact our results of operations in the near term.

We believe our long-term value as a company will be greater if we focus on longer-term growth over short-term results. As a result, our results of operations may be negatively impacted in the near term relative to a strategy focused on maximizing short-term profitability. Significant expenditures on marketing efforts, potential acquisitions and other expansion efforts may not ultimately grow our business or lead to expected long-term results.

Our business and the markets in which we operate are new and rapidly evolving, which make it difficult to evaluate our future prospects and the risks and challenges we may encounter.

Our business and the markets in which we operate are new and rapidly evolving, which make it difficult to evaluate and assess the success of our business to date, our future prospects and the risks and challenges that we may encounter. These risks and challenges include our ability to:

attract new customers for our tests through patient awareness, sales and marketing campaigns, as well as through key channel partners;

gain market acceptance of our current and future tests and services with key constituencies and maintain and expand such relationships;

comply with existing and new laws and regulations applicable to our business and in our industry;

anticipate and respond to changes in payor reimbursement rates and the markets in which we operate;

react to challenges from existing and new competitors;

maintain and enhance our reputation and brand;

effectively manage our growth and business operations, including new geographies;

accurately forecast our revenue and budget for, and manage, our expenses, including capital expenditures; and

hire and retain talented individuals at all levels of our organization;

If we fail to understand fully or adequately address the challenges that we are currently encountering or that we may encounter in the future, including those challenges described here and elsewhere in this “Risk Factors” section, our business, financial condition and results of operations could be adversely affected. If the risks and uncertainties that we plan for when operating our business are incorrect or change, or if we fail to manage these risks successfully, our results of operations could differ materially from our expectations and our business, financial condition and results of operations could be adversely affected.

Our limited operating history makes it difficult to evaluate our future prospects and the risks and challenges we may encounter.

We were established in 2017, and we are continuing to grow our marketing and management capabilities. Consequently, predictions about our future success or viability may not be as accurate as they could be if we had a longer operating history. The evolving nature of the medical diagnostics industry increases these uncertainties. If our growth strategy is not successful, we may not be able to continue to grow our revenue or operations. Our limited operating history, evolving business and growth make it difficult to evaluate our future prospects and the risks and challenges we may encounter.

In addition, as a business with a limited operating history, we may encounter unforeseen expenses, difficulties, complications, delays and other known and unknown challenges. We may not be successful at commercialization, sales and marketing and, as a result, our business may be adversely affected.

Our quarterly results may fluctuate significantly and may not fully reflect the underlying performance of our business.

Our results of operations and key metrics discussed elsewhere in this Annual Report on Form 10-K may vary significantly in the future and period-to-period comparisons of our operating results and key metrics may not provide a full picture of our performance. Accordingly, the results of any one quarter or year should not be relied upon as an indication of future performance. Our quarterly financial results and metrics may fluctuate as a result of a variety of factors, many of which are outside of our control, and as a result they may not fully reflect the underlying performance of our business. These quarterly fluctuations may negatively affect the value of our securities. Factors that may cause these fluctuations include, without limitation:

the level of demand for our tests and services, which may vary significantly from period to period;

our ability to attract new customers, whether patients or strategic channel partners or other customers;

the timing of recognition of revenues;

the amount and timing of operating expenses;

	·	general economic, industry and market conditions, both domestically and internationally, including any economic downturns and adverse impacts resulting from the COVID- 19 pandemic and/or the military conflicts between Russia and Ukraine or in Iran;
	·	the timing of our billing and collections;

adoption rates by participants in our key channels;

increases or decreases in the number of patients, providers and organizations that use our tests or pricing changes upon any signing and renewals of agreements with healthcare sub-vertical channel partners;

changes in our pricing policies or those of our competitors;

the timing and success of new offerings by us or our competitors or any other change in the competitive dynamics of our industry, including consolidation among competitors, practitioners, clinics or outsourcing facilities; extraordinary expenses such as litigation or other dispute-related expenses or settlement payments;

extraordinary expenses such as litigation or other dispute-related expenses or settlement payments;

sales tax and other tax determinations by authorities in the jurisdictions in which we conduct business;

the impact of new accounting pronouncements and the adoption thereof;

fluctuations in stock-based compensation expenses;

expenses in connection with mergers, acquisitions or other strategic transactions;

changes in regulatory and licensing requirements;

the amount and timing of expenses related to our expansion to markets outside the United States; and

the timing of expenses related to the development or acquisition of technologies or businesses and potential future charges for impairment of goodwill or intangibles from acquired companies.

Further, although our revenues currently are only nominal, once we achieve traction, in any future period, our revenue growth could slow or our revenues could decline for a number of reasons, including slowing demand for our tests and services, increasing competition, a decrease in the growth of our overall market, or our failure, for any reason, to continue to capitalize on growth opportunities. In addition, our growth rate may slow in the future as our market penetration rates increase. As a result, our revenues, operating results and cash flows may fluctuate significantly on a quarterly basis and revenue growth rates may not be sustainable and may decline in the future, and we may not be able to achieve or sustain profitability in future periods, which could harm our business and cause the market price of our Common Stock to decline.

We expect to need to raise additional capital to fund our existing operations or develop and commercialize new services or expand our operations.

We expect to spend significant amounts to expand our existing operations, including expansion into new geographies, to make additional key hires, to expand our sales channels and constituencies and to develop new tests and services. Since 2024, our primary source of capital has been sales of our Common Stock under our at-the-market agreement with Craig-Hallum Capital Group, LLC (the “ATM Agreement”). If we are unable to raise additional capital under the ATM Agreement or otherwise, we may need to delay the timing of, or scale back, certain aspects of our business plan and operations. The estimate and our expectation regarding the sufficiency of funds to continue our business plan and operations are based on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we currently expect. Until such time, if ever, as we can generate sufficient revenues, we expect to finance our cash needs through a combination of equity offerings and debt financings or other sources. In addition, we may seek additional capital in the event of favorable market conditions or strategic considerations, even if we believe that we have sufficient funds for our current or future operating plans.

Our present and future funding requirements will depend on many factors, including:

our ability to achieve revenue growth;

our ability to effectively manage our expenses and burn;

the cost of expanding our operations, including our geographic scope, and our offerings, including our marketing efforts;

our rate of progress in launching, commercializing and establishing adoption of our tests and services; and

the effect of competing technological and market developments.

To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a securityholder. In addition, debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may be required to relinquish valuable rights to our technologies, intellectual property, or future revenue streams or grant licenses on terms that may not be favorable to us. Furthermore, any capital raising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to advance development activities. If we need additional capital and cannot raise it on acceptable terms, or at all, we may not be able to, among other things:

invest in our business and continue to grow our brand and expand our customer and patient bases;

hire and retain employees, including scientists and medical professionals, operations personnel, financial and accounting staff, and sales and marketing staff;

respond to competitive pressures or unanticipated working capital requirements; or

pursue opportunities for acquisitions of, investments in, or strategic alliances and joint ventures with complementary businesses.

We may invest in or acquire other businesses, and our business may suffer if we are unable to successfully integrate an acquired business into our company or otherwise manage the growth associated with multiple acquisitions.

From time to time, we may acquire, make investments in, or enter into strategic alliances and joint ventures with, complementary businesses. These transactions may involve significant risks and uncertainties, including:

In the case of an acquisition:

The potential for the acquired business to underperform relative to our expectations and the acquisition price;

The potential for the acquired business to cause our financial results to differ from expectations in any given period, or over the longer-term;

Unexpected tax consequences from the acquisition, or the tax treatment of the acquired business’s operations going forward, giving rise to incremental tax liabilities that are difficult to predict;

Difficulty in integrating the acquired business, its operations, and its employees in an efficient and effective manner;

Any unknown liabilities or internal control deficiencies assumed as part of the acquisition; and

The potential loss of key employees of the acquired businesses.

In the case of an investment, alliance, joint venture, or other partnership:

Our ability to cooperate with our co-venturer;

Our co-venturer having economic, business, or legal interests or goals that are inconsistent with ours; and

The potential that our co-venturer may be unable to meet is economic or other obligations, which may require us to fulfill those obligations alone or find a suitable replacement.

Any such transaction may involve the risk that our senior management’s attention will be excessively diverted from our other operations, the risk that our industry does not evolve as anticipate, and that any intellectual property or personnel skills acquired do not prove to be those needed for our future success, and the risk that our strategic objectives, cost savings or other anticipate benefits are otherwise not achieved.

We may experience difficulties in managing our growth and expanding our operations.

We expect to experience significant growth in the scope of our operations. Our ability to manage our operations and future growth will require us to continue to improve our operational, financial and management controls, compliance programs and reporting systems. We may not be able to implement improvements in an efficient or timely manner and may discover deficiencies in existing controls, programs, systems and procedures, which could have an adverse effect on our business, reputation and financial results. Additionally, rapid growth in our business may place a strain on our human and capital resources.

Risks Related to our Business and Industry

We have an unproven business model with no assurance of significant revenues or operating profit.

Our current business model is unproven and the profit potential, if any, is unknown at this time. We are subject to all of the risks inherent in the creation of a new business. Our ability to achieve profitability is dependent, among other things, on our initial marketing and accompanying product acceptance to generate sufficient operating cash flow to fund current operations and future expansion. There can be no assurance that our results of operations or business strategy will achieve significant revenue or profitability.

The market for epigenetic tests is fairly new and unproven, and it may decline or experience limited growth, which would adversely affect our ability to fully realize the potential of our platform.

Epigenetics is at the heart of our technology, products and services. According to the CDC, epigenetics is the study of how a person’s behaviors and environment can cause changes that affect the way a person’s genes work. Unlike genetic changes, epigenetic changes are reversible and do not change one’s DNA sequence, but they can change how a person’s body reads a DNA sequence. The market for epigenetic tests is relatively new and evaluating the size and scope of the market is subject to a number of risks and uncertainties. We believe that our future success will depend in large part on the growth of this market. The utilization of our solution is still relatively new, and customers may not recognize the need for, or benefits of, our tests and services, which may prompt them to cease use of our tests and services or decide to adopt alternative products and services to satisfy their healthcare requirements. In order to expand our business and extend our market position, we intend to focus our marketing and sales efforts on educating customers about the benefits and technological capabilities of our tests and services and the application of our tests and services to specific needs of customers in different market verticals. Our ability to access and expand the market that our tests and services are designed to address depends upon a number of factors, including the cost, performance and perceived value of the tests and services. Market opportunity estimates are subject to significant uncertainty and are based on assumptions and estimates. Assessing the market for our solutions in each of the vertical markets we are competing in, or planning to compete in, is particularly difficult due to a number of factors, including limited available information and rapid evolution of the market. The market for our tests and services may fail to grow significantly or be unable to meet the level of growth we expect. As a result, we may experience lower-than-expected demand for our products and services due to lack of customer acceptance, technological challenges, competing products and services, decreases in expenditures by current and prospective customers, weakening economic conditions and other causes. If our market share does not experience significant growth, or if demand for our solution does not increase, then our business, results of operations and financial condition will be adversely affected.

Market opportunity estimates and growth forecasts are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. The estimates and forecasts in this Annual Report on Form 10-K relating to the size and expected growth of the cardiovascular diagnostics market may prove to be inaccurate. Even if the market in which we compete meets our size estimates and forecasted growth, our business could fail to grow at similar rates, if at all.

Our ability to attract new customers and increase revenue from existing customers depends in part on our ability to enhance and improve our solutions, increase adoption and usage of our products and introduce new products and features. The success of any enhancements or new products depends on several factors, including timely completion, adequate quality testing, actual performance quality, market-accepted pricing levels and overall market acceptance and demand. Enhancements and new products that we develop may not be introduced in a timely or cost-effective manner, may contain defects, may have interoperability difficulties with our solutions, or may not achieve the market acceptance necessary to generate significant or any revenue. If we are unable to successfully enhance our existing solutions and capabilities to meet evolving customer requirements, increase adoption and usage of our solutions, develop new products, or if our efforts to increase the usage of our products are more expensive than we expect, then our business, results of operations and financial condition could be harmed.

The success of our business depends on our ability to expand into new vertical markets and attract new customers in a cost-effective manner.

In order to grow our business, we plan to drive greater awareness and adoption of our tests and services from customers across new vertical markets. We intend to increase our investment in sales and marketing, as well as in technological development, to meet evolving customer needs in these and other markets. There is no guarantee, however, that we will be successful in gaining new customers from existing and new markets. We have limited experience in marketing and selling our products and services generally, and in particular in new markets, which may present unique and unexpected challenges and difficulties. Furthermore, we may incur additional costs to modify our current solutions to conform to the customer’s requirements, and we may not be able to generate sufficient revenue to offset these costs. We may also be required to comply with certain regulations required by government customers, which will require us to incur costs, devote management time and modify our current solutions and operations. If we are unable to comply with those regulations effectively and in a cost-effective manner, our financial results could be adversely affected.

If the costs of the new marketing channels we use or plan to pursue increase dramatically, then we may choose to use alternative and less expensive channels, which may not be as effective as the channels we currently use or have plans to use. As we add to or change the mix of our marketing strategies, we may need to expand into more expensive channels than those we are currently in, which could adversely affect our business, results of operations and financial condition. In addition, we have limited experience marketing our products and services and we may not be successful in selecting the marketing channels that will provide us with exposure to customers in a cost-effective manner. As part of our strategy to penetrate the new vertical markets, we expect to incur marketing expenses before we are able to recognize any revenue in such markets, and these expenses may not result in increased revenue or brand awareness. We expect to make significant expenditures and investments in new marketing activities, and these investments may not lead to the cost-effective acquisition of additional customers. If we are unable to maintain effective sales and marketing programs, then our ability to attract new customers or enter into new vertical markets could be adversely affected.

Consolidation in the health care industry could have a material adverse effect on our business, financial condition and results of operations.

Many health care industry participants and payers are consolidating to create larger and more integrated health care delivery systems with greater market power. We expect regulatory and economic conditions to result in additional consolidation in the health care industry in the future. As consolidation accelerates, the economies of scale of our customers’ organizations may grow. If a customer experiences sizable growth following consolidation, that customer may determine that it no longer needs to rely on us and may reduce its demand for our products and services. In addition, as health care providers consolidate to create larger and more integrated health care delivery systems with greater market power, these providers may try to use their market power to negotiate price reductions for our products and services. Finally, consolidation may also result in the acquisition or future development by our customers of products and services that compete with our products and services. Any of these potential results of consolidation could have a material adverse effect on our business, financial condition and results of operations.

If we are not able to compete effectively, our business and operating results will be harmed.

The market for our tests and services is increasingly competitive, rapidly evolving and fragmented, and is subject to changing technology and shifting customer needs. Although we believe that the solutions that we offer are unique, many companies develop and market products and services that compete to varying extents with our offerings, and we expect competition in our market to continue to intensify. Moreover, industry consolidation may increase competition.

While the clinical epigenetics market is still fairly new, we face competition from various sources, including large, well-capitalized technology companies such as Cleerly and Prevencio. These competitors may have better brand name recognition, greater financial and engineering resources and larger sales teams than we have. As a result, our competitors may be able to develop and introduce competing solutions and technologies that may have greater capabilities than our solutions or that are able to achieve greater customer acceptance, and they may be able to respond more quickly and effectively than we can to new or changing opportunities, technologies, standards or customer requirements. In addition, we may also compete with smaller companies, who may develop their own platforms that perform similar services as our platform. We expect that competition will increase and intensify as we continue to expand our serviceable markets and improve our tests and services. If we are unable to provide our tests and services on terms attractive to the customer, the prospective customer may be unwilling to utilize our solutions. If our competitors’ products, services or technologies become more accepted than our solutions, if they are successful in bringing their products or services to market earlier than we do, or if their products or services are more technologically capable than ours, then our revenue could be adversely affected. In addition, increased competition may result in pricing pressures and require us to incur additional sales and marketing expenses, which could negatively impact our sales, profitability and market share.

Our business depends on customers increasing their use of our solutions, and we may experience loss of customers or decline in their use of our solutions.

Our ability to grow and generate revenue depends, in part, on our ability to maintain and grow our relationships with existing customers and convince them to increase their usage of our tests and services. If our customers do not increase their use of our tests and services, then our revenue may not grow, and our results of operations may be harmed. It is difficult to accurately predict customers’ usage levels and the loss of customers or reductions in their usage levels may have a negative impact on our business, results of operations and financial condition. If a significant number of customers cease using, or reduce their usage of our tests and services, then we may be required to expend significantly more on sales and marketing than we currently plan to expend in order to maintain or increase revenue from customers. These additional expenditures could adversely affect our business, results of operations and financial condition.

Our technologies and products leverage and incorporate AI and machine learning, and their development, maintenance, and operational success are subject to various risks and uncertainties, some of which are beyond our control and may adversely affect our business, results of operations and financial condition, and may also result in reputational harm and liability.

One of the key components of our technology and solutions is the use of machine learning/artificial intelligence (“ML/AI”). While we have made, and expect to continue to make, investments in the continued development of AI capabilities, adoption of fast changing AI technology presents risks, challenges and potential unintended consequences. Also, the markets for our solutions and services are rapidly evolving and are highly competitive, and many of our competitors are also seeking to incorporate AI into their products. Competing firms may be able to develop and embed AI in their products more quickly than we can. If our competitors are better able to incorporate AI in their products and we are unable to compete effectively with them, our business, results of operations and financial condition could be adversely affected.

Our ML/AI powering our technology and products, there are known risks with the use of ML/AI including accuracy, bias, toxicity, privacy, security and data provenance. Developing, testing and deploying ML/AI systems may also increase the cost of our offerings. Our failure to adequately address potential risks relating to the use of ML/AI in our technology and solutions could result in litigation regarding, among other things, intellectual property, privacy and other claims that could result in liability for our company. It may also result in new or increased governmental or regulatory scrutiny, which could result in regulatory action, legal liabilities, regulatory penalties, and damage to our reputation, potentially harming our business and financial condition. The use of our AI capabilities could raise ethical or social concerns and our failure to adequately address these concerns or the failure of our competitors, clients or other end users to do so could negatively impact our brand and reputation.

Our success in ML/AI technologies depends significantly on the continued service of our key technical personnel especially our Chief Technology Officer and our Chief Executive Officer, and our ability to attract and retain skilled professionals in a competitive market. The loss of key personnel or the inability to hire and retain the necessary talent could adversely affect our technological competitiveness and operational capabilities.

Interruptions or performance problems associated with our technology and infrastructure may adversely affect our business and operating results.

Our continued growth depends in part on the ability of customers to access its tests and services at any time and within an acceptable amount of time. We may in the future experience disruptions, outages and other performance problems due to a variety of factors, including challenges with suppliers, infrastructure changes, introductions of new applications and functionality, software errors and defects, capacity constraints due to an increasing number of customers or security related incidents. In addition, from time-to-time, we or our vendors may experience limited periods of equipment downtime, server downtime due to server failure or other technical difficulties (as well as maintenance requirements). It may become increasingly difficult to maintain and improve our performance, especially during high volume times and as our solution becomes more complex and our customer demand and traffic increases. If our solution is unavailable or if our customers are unable to access our solutions within a reasonable amount of time or at all, our business would be adversely affected, and its brand could be harmed. In the event of any of the factors described above, or certain other failures of our infrastructure, customer or patient data may be permanently lost. To the extent that we do not effectively address capacity constraints, upgrade our systems, as needed, and continually develop our technology and network architecture to accommodate actual and anticipated changes in technology, customers may cease to use our solutions and our business and operating results may be adversely affected.

The security of our solutions, networks or computer systems may be breached, and any unauthorized access to our customer data will have an adverse effect on our business and reputation.

The use of our solutions involves the storage, transmission and processing of our customers’ private data, and this data may contain confidential and proprietary information of our customers or their customers, patients, employees, business partners or other persons (“customer personnel”) or other personal or identifying information regarding our customers and customer personnel. Individuals or entities may attempt to penetrate our network or platform security, or that of our third-party hosting and storage providers, and could gain access to our customer and customer personnel private data, which could result in the destruction, disclosure or misappropriation of proprietary or confidential information of our customers and customer personnel. If any of our customers’ or customer personnel’s private data is leaked, obtained by others or destroyed without authorization, it could harm our reputation, we could be exposed to civil and criminal liability, and we may lose our ability to access private data, which will adversely affect the quality and performance of our solutions.

In addition, our platform and services may be subject to computer malware, viruses and computer hacking, fraudulent use attempts and phishing attacks, all of which have become more prevalent in our industry. Though it is difficult to determine what, if any, harm may directly result from any specific interruption or attack, they may include the theft or destruction of data owned by us or our customers or customer personnel, and/or damage to our platform. Any failure to maintain the performance, reliability, security and availability of our products and technical infrastructure to the satisfaction of our customers may harm our reputation and our ability to retain existing customers and attract new customers.

While we have implemented and are continuing to implement procedures and safeguards that are designed to prevent security breaches and cyberattacks, they may not be able to protect against all attempts to breach our systems, and we may not become aware in a timely manner of any such security breach. Unauthorized access to or security breaches of our platform, network or computer systems, or those of our technology service providers, could result in the loss of business, reputational damage, regulatory investigations and orders, litigation, indemnity obligations, damages for contract breach, civil and criminal penalties for violation of applicable laws, regulations or contractual obligations and significant costs, fees and other monetary payments for remediation. If customers believe that our platform does not provide adequate security for the storage of sensitive information or its transmission over the Internet, our business will be harmed. Customers’ concerns about security or privacy may deter them from using our solutions for activities that involve personal or other sensitive information.

We maintain cybersecurity coverage; however, this coverage may not continue to be available on acceptable terms, may not be available in sufficient amounts to cover one or more large claims against us, and may include larger self-insured retentions or certain exclusions. In addition, the insurer might disclaim coverage as to any future claim. A successful claim not fully covered by our insurance could have a material adverse impact on our liquidity, financial condition, and results of operations.

Any failure to offer high-quality customer support may adversely affect our relationships with our customers.

Our ability to retain existing customers and attract new customers depends in part on our ability to maintain a consistently high level of customer service and technical support. Our current and future customers depend on our customer support team to assist them in utilizing our tests and services effectively and to help them to resolve issues quickly and to provide ongoing support. If we are unable to hire and train sufficient support resources or are otherwise unsuccessful in assisting our customers effectively, it could adversely affect our ability to retain existing customers and could prevent prospective customers from adopting our solutions. We may be unable to respond quickly enough to accommodate short-term increases in demand for customer support. We also may be unable to modify the nature, scope and delivery of our customer support to compete with changes in the support services provided by our competitors. Increased demand for customer support, without corresponding revenue, could increase our costs and adversely affect our business, results of operations and financial condition. Our sales are and will be highly dependent on our business reputation and on positive recommendations from customers. Any failure to maintain high-quality customer support, or a market perception that we do not maintain high-quality customer support, could adversely affect our reputation, business, results of operations and financial condition.

The information that we provide to our customers could be inaccurate or incomplete, which could harm our business reputation, financial condition, and results of operations.

We aggregate, process, and analyze customers’/patients’ healthcare-related data and information for use by our customers. Because data in the healthcare industry is fragmented in origin, inconsistent in format, and often incomplete, the overall quality of data received or accessed in the healthcare industry is often poor, the degree or amount of data which is knowingly or unknowingly absent or omitted can be material. If the test results that we provide to our customers are based on incorrect or incomplete data or if we make mistakes in the capture, input, or analysis of these data, our reputation may suffer, and our ability to attract and retain customers may be materially harmed.

In addition, in the future, we may assist our customers with the management and submission of data to governmental entities, including CMS. These processes and submissions are governed by complex data processing and validation policies and regulations. If we fail to abide by such policies or submits incorrect or incomplete data, we may be exposed to liability to a client, court, or government agency that concludes that its storage, handling, submission, delivery, or display of health information or other data was wrongful or erroneous.

Our proprietary applications may not operate properly, which could damage our reputation, give rise to a variety of claims against us, or divert our resources from other purposes, any of which could harm our business and operating results.

Proprietary software, product and application development is time-consuming, expensive, and complex, and may involve unforeseen difficulties. We may encounter technical obstacles, and it is possible that we discover additional problems that prevent our proprietary solutions from operating properly. If our solutions and services do not function reliably or fail to achieve customer expectations in terms of performance, customers could assert liability claims against us and attempt to cancel their contracts with us. Moreover, material performance problems, defects, or errors in our existing or new solutions may arise in the future and may result from, among other things, the lack of interoperability of our applications with systems and data that we did not develop and the function of which is outside of our control or undetected in our testing. Defects or errors in our solutions might discourage existing or potential customers from purchasing products and services from us. Correction of defects or errors could prove to be time consuming, costly, impossible, or impracticable. The existence of errors or defects in our solutions and the correction of such errors could divert our resources from other matters relating to its business, damage our reputation, increase our costs, and have a material adverse effect on our business, financial condition, and results of operations.

If we do not keep pace with technological changes, our solutions may become less competitive, and our business may suffer.

The clinical epigenetic testing, artificial intelligence/machine learning-based solutions and the cardiovascular diagnostics markets are undergoing rapid technological change, frequent product and service innovation and evolving industry standards. If we are unable to provide enhancements and new features for our existing tests and services or additional tests and services that achieve market acceptance or that keep pace with these technological developments, our business could be adversely affected. The success of enhancements, new tests and services depends on several factors, including the timely completion, introduction and market acceptance of the innovations. Failure in this regard may significantly impair our revenue growth. In addition, because our solutions are designed to operate on existing cloud software and technologies, we will need to continuously modify and enhance our solutions to keep pace with changes in internet-related hardware, software, communication, browser and database technologies, alongside changes in laboratory technologies. We may not be successful in either developing these modifications and enhancements or in bringing them to market in a timely fashion. Furthermore, uncertainties about the timing and nature of new diagnostic tests, network platforms or technologies, including laboratory technologies, or modifications to existing tests, platforms or technologies, could increase our research and development expenses. Any failure of our solutions to keep pace with technological changes or operate effectively with future network platforms and technologies, including laboratory technologies, could reduce the demand for our solutions, result in customer dissatisfaction and adversely affect our business.

Our growth strategy may not prove viable and expected growth and value may not be realized.

While our overall sales and marketing initiatives will span the gamut across traditional, print and digital mediums, our primary sales and marketing strategy consists of the branding, collaboration, co-marketing, and co-sales opportunities involved in strategic channel partnerships. By prioritizing strategic channel partnerships, we believe we can accelerate our market penetration into the key healthcare sub-verticals we intend to prioritize for our growth. The key to our efforts is a well-defined and executed channel partnership integration strategy that we believe will serve to accelerate the sales cycle. Although there is no assurance, we believe such strategic channel partnerships will generate revenue in a myriad of ways, including larger contracts for our Epi+Gen CHD™ and PrecisionCHD™ tests, our HeartRisk platform, and bundling our solutions alongside other synergistic technologies, services, and products. There can be no assurance that we will be successful in acquiring customers through these and other strategies.

Market and economic conditions may negatively impact our business, financial condition and stock price.

Concerns over inflation, energy costs, geopolitical issues, including the ongoing conflict between Russian and Ukraine and the recent commencement of hostilities in Iran, unstable global credit markets and financial conditions, and volatile oil prices could lead to periods of significant economic instability, diminished liquidity and credit availability, declines in consumer confidence and discretionary spending, diminished expectations for the global economy and expectations of slower global economic growth going forward. Our general business strategy may be adversely affected by any such inflationary fluctuations, economic downturns, volatile business environments and continued unstable or unpredictable economic and market conditions.

Additionally, rising costs of goods and services purchased by us, including raw materials used in manufacturing our tests, may have an adverse effect on our gross margins and profitability in future periods. If economic and market conditions continue to deteriorate or do not improve, it may make any necessary debt or equity financing more difficult to complete, more costly and more dilutive to our stockholders. Failure to secure any necessary financing in a timely manner or on favorable terms could have a material adverse effect on our financial performance and stock price or could require us to delay or abandon development other business plans. In addition, there is a risk that one or more of our current and future service providers, manufacturers, suppliers, other partners could be negatively affected by such difficult economic factors, which could adversely affect our ability to attain our operating goals on schedule and on budget or meet our business and financial objectives.

Our success depends upon our ability to adapt to a changing market and our continued development of additional tests and services.

Although we believe that we will provide a competitive range of tests and services, there can be no assurance of acceptance by the marketplace. The procurement of new contracts by us may be dependent upon the continuing results achieved with current and future customers, upon pricing and operational considerations, as well as the potential need for continuing improvement to existing products and services. Moreover, the markets for such services may not develop as expected nor can there be any assurance that we will be successful in our marketing of any such products and services.

Compliance with changing regulation of corporate governance and public disclosure result in significant additional expenses.

Changing laws, regulations, and standards relating to corporate governance and public disclosure for public companies, including the Sarbanes-Oxley Act of 2002 and various rules and regulations adopted by the SEC, are creating uncertainty for public companies. Our management needs to invest significant time and financial resources to comply with both existing and evolving requirements for public companies, which leads, among other things, to significantly increased general and administrative expenses and diversion of management time and attention from revenue generating activities to compliance activities.

Risks Related to our Business Operations

We could experience losses or liability not covered by insurance.

Our business exposes us to risks that are inherent in the provision of testing services that assist clinical decision-making. If customers or customer personnel assert liability claims against us, any ensuing litigation, regardless of outcome, could result in a substantial cost to the Company, divert management’s attention from operations, and decrease market acceptance of our solutions. The limitations of liability set forth in any contracts we may enter into now or in the future may not be enforceable or may not otherwise protect us from liability for damages. Additionally, we may be subject to claims that are not explicitly covered by a contract. We also maintain general liability coverage; however, this coverage may not continue to be available on acceptable terms, may not be available in sufficient amounts to cover one or more large claims against us, and may include larger self-insured retentions or exclusions for certain products. In addition, the insurer might disclaim coverage as to any future claim. A successful claim not fully covered by our insurance could have a material adverse impact on our liquidity, financial condition, and results of operations.

Our future growth could be harmed if we lose the services of our key personnel.

We are highly dependent upon the talents and services of a number of key employees, specifically Meeshanthini Dogan, PhD, Robert Philibert, MD PhD and Timur Dogan, PhD, and other senior technical and management personnel, including our other executive officers, all of whom would be difficult to replace. In 2022, we entered into multi-year employment agreements with each of our executive officers and a consulting agreement with our non-executive chairman. The loss of the services of one or more of these key employees would disrupt our business and harm its results of operations. As competition is intense for the type of highly skilled scientific and medical professionals our business requires, we may not be able to successfully attract and retain senior leadership necessary to grow our business.

If we are unable to hire, retain and motivate qualified personnel, our business will suffer.

Our future success depends, in part, on our ability to continue to attract and retain highly skilled personnel. We believe that there is, and will continue to be, intense competition for highly skilled management, medical, engineering, data science, sales and other personnel with experience in our industry. We must provide competitive compensation packages and a high-quality work environment to hire, retain and motivate employees. If we are unable to retain and motivate our existing employees and attract qualified personnel to fill key positions, we may be unable to manage our business effectively, including the development, marketing and sale of our products, which could adversely affect our business, results of operations and financial condition. To the extent we hire personnel from competitors, we also may be subject to allegations that they have been improperly solicited or that they have divulged proprietary or other confidential information. If we are unable to retain our employees, our business, results of operations and financial condition could be adversely affected.

If we cannot maintain our corporate culture as it grows, we could lose the innovation, teamwork, passion and focus on execution that it believes contribute to its success, and its business may be harmed.

We believe that our corporate culture is a critical component to our success. We have and will continue to invest substantial time and resources in building our team. As we grow and develop the infrastructure of a public company, we may find it difficult to maintain our corporate culture. Any failure to preserve our culture could negatively affect our future success, including our ability to retain and recruit personnel and effectively focus on and pursue our corporate objectives.

We may be unable to manage our growth.

Currently, we have less than 15 full and two part-time employees. Our ability to manage our growth effectively will require us to continue to improve our operational, financial and management controls and information systems to accurately forecast sales demand, to manage our operating costs, manage our marketing programs in conjunction with an emerging market, and attract, train, motivate and manage our employees effectively. Our growth strategy will place significant demands on our management team and our financial, administrative and other resources. Operating results will depend substantially on the ability of our officers and key employees to manage changing business conditions and to implement and improve its financial, administrative and other resources. If management fails to manage the expected growth, our results of operations, financial condition, business and prospects could be adversely affected. In addition, our growth strategy may depend on effectively integrating future entities, which requires cooperative efforts from the managers and employees of the respective business entities. If we are unable to respond to and manage changing business conditions, or the scale of our operations, then the quality of our products and services, our ability to retain key personnel, and our business could be harmed, which in turn, could adversely affect our results of operations, financial condition, business and prospects.

Our Board of Directors may change its strategies, policies, and procedures without stockholder approval, and we may become highly leveraged, which may increase our risk of default under our existing or future obligations.

Our investment, financing, leverage, and dividend policies, and our policies with respect to all other activities, including growth, capitalization, and operations, are determined exclusively by our board of directors, and may be amended or revised at any time by our board of directors without notice to or a vote of our stockholders. This could result in the Company conducting operational matters, making investments, or pursuing different business or growth strategies than those contemplated in this Annual Report on Form 10-K. Further, our charter and bylaws do not limit the amount or percentage of indebtedness, funded or otherwise, that we may incur. High leverage also increases the risk of default on our obligations. In addition, a change in our investment policies, including the manner in which we allocate our resources across our portfolio or the types of assets in which we seek to invest, may increase our exposure to interest rate risk and liquidity risk. Changes to our policies with regards to the foregoing could materially adversely affect our financial condition, results of operations, and cash flow.

Our business is subject to the risks of earthquakes, fire, floods, pandemics and other natural catastrophic events, and to interruption by man-made problems, such as power disruptions, computer viruses, data security breaches or terrorism.

A significant natural disaster, such as a tornado, hurricane or a flood, occurring at our headquarters or where a business partner is located could adversely affect our business, results of operations and financial condition. Further, if a natural disaster or man-made problem were to affect our network service providers or Internet service providers, this could adversely affect the ability of our customers to use our products and platform. In addition, health epidemics or pandemics, natural disasters and acts of terrorism could cause disruptions in our business, or the businesses of our customers or service providers. We also rely, and will continue to rely, on our network and third-party infrastructure and enterprise applications and internal technology systems for our engineering, sales and marketing and operations activities. In the event of a major disruption caused by a health epidemic or pandemic, natural disaster or man-made problem, we may be unable to continue our operations and may endure system interruptions, reputational harm, delays in our development activities, lengthy interruptions in service, breaches of data security and loss of critical data, any of which could adversely affect our business, results of operations and financial condition.

We may need to seek alternative business opportunities and change the nature of our business.

As a company in the early stages of its development, we continuously reevaluate our business, the market in which we operate and potential new opportunities. We may seek other alternatives within the healthcare field in order to grow our business and increase revenues. Such alternatives may include, but not be limited to, combinations or strategic partnerships with laboratory companies or with medical practices such as hospitalists or behavioral health. Pursuing alternative business opportunities could increase our expenses, may require us to obtain additional financing, which may not be available on favorable terms or at all, and result in potentially dilutive issuances of our equity securities or the incurrence of debt that may be burdensome to service, any of which could have a material adverse effect on our business and operations. In addition, pursuing alternative business opportunities may never be successful and may divert significant management time and attention. Moreover, accomplishing and integrating any business opportunity that is pursued by us may disrupt the existing business and may be a complex, risky and costly endeavor and could have a material adverse effect on our business, results of operations, financial condition and prospects.

Any legal proceedings or claims against us could be costly and time-consuming to defend and could harm our reputation regardless of the outcome.

We may in the future become subject to legal proceedings and claims that arise in the ordinary course of business, including intellectual property, collaboration, licensing agreement, product liability, employment, class action, whistleblower and other litigation claims, and governmental and other regulatory investigations and proceedings. Such matters can be time-consuming, divert management’s attention and resources, cause us to incur significant expenses or liability, or require us to change our business practices. In addition, the expense of litigation and the timing of this expense from period to period are difficult to estimate, subject to change, and could adversely affect our financial condition and results of operations. Because of the potential risks, expenses, and uncertainties of litigation, we may, from time to time, settle disputes, even where we have meritorious claims or defenses, by agreeing to settlement agreements. Any of the foregoing could adversely affect our business, financial condition, and results of operations.

Risks Related to our Intellectual Property

Our license agreement with the University of Iowa Research Foundation includes a non-exclusive license of “technical information” that potentially could grant unaffiliated third parties access to materials and information considered derivative work made by us, which could be used by such licensees to develop competitive products.

The University of Iowa Research Foundation, or UIRF, license agreement grants to us a worldwide, exclusive, non-transferable license under the Patent Rights, as defined in the agreement, to make, have made, use, sell, offer for sale and import the Licensed Products(s) and/or Licensed Processes, as defined in the agreement, in the field of research tools and clinical diagnostics for cardiovascular disease, stroke, congestive heart failure and diabetes in humans. However, the agreement also confers a non-exclusive license as to Technical Information. Technical Information is defined as certain research and development information, materials, confidential information, technical data, unpatented inventions, know-how and supportive information owned and controlled by the licensor that was not in the public domain as of May 2, 2017 and that describes the Invention, as defined in the agreement, its manufacture and/or use and selected by the licensor to provide to us for use in or with the development, manufacture or use of the Licensed Products and/or Licensed Processes. Technical Information further includes materials, all progeny and derivatives of the materials made by us or our sublicensees, as well as software or other copyrightable work, all derivatives of such software and other copyrightable work made by us and our sublicensees. The ability of UIRF to grant non-exclusive licenses to third parties in and to this broad definition of Technical Information raises the possibility that unaffiliated third parties could use such Technical Information, including Technical Information used by the Company, to make, use, sell, offer to sell and import products and/or processes that compete with the Company’s exclusively-licensed products and/or processes or are positioned in markets that the Company may enter in the future. Increased competition could result in reduced demand for the Company’s products and/or processes, slow its growth and materially adversely affect its business, operating results and financial condition.

We could incur substantial costs in protecting or defending our intellectual property rights, and any failure to protect or defend our intellectual property could adversely affect our business, results of operations and financial condition.

Our success depends, in part, on our ability to protect our brand and the proprietary methods and technologies that we develop under patent and other intellectual property laws of the United States and foreign jurisdictions so that we can prevent others from using our inventions and proprietary information. Any patents that have been issued or that may be issued in the future may not provide significant protection for our intellectual property. If we fail to protect our intellectual property rights adequately, our competitors might gain access to our technology and our business, results of operations and financial condition may be adversely affected.

The particular forms of intellectual property protection that we seek, or our business decisions about when to file patent applications and trademark applications, may not be adequate to protect our business. We could be required to expend significant resources to monitor and protect our intellectual property rights. Litigation may be necessary in the future to enforce our intellectual property rights, determine the validity and scope of our proprietary rights or those of others, or defend against claims of infringement or invalidity. Such litigation could be costly, time-consuming and distracting to management, result in a diversion of significant resources, lead to the narrowing or invalidation of portions of our intellectual property and have an adverse effect on our business, results of operations and financial condition. Our efforts to enforce our intellectual property rights may be met with defenses, counterclaims and countersuits attacking the validity and enforceability of our intellectual property rights or alleging that we infringe the counterclaimant’s own intellectual property. Any of our patents, copyrights, trademarks or other intellectual property rights could be challenged by others or invalidated through administrative process or litigation.

We also rely, in part, on confidentiality agreements with our business partners, employees, consultants, advisors, customers and others in our efforts to protect our proprietary technology, processes and methods. These agreements may not effectively prevent disclosure of our confidential information, and it may be possible for unauthorized parties to copy our software or other proprietary technology or information, or to develop similar technology independently without our having an adequate remedy for unauthorized use or disclosure of our confidential information. In addition, others may independently discover our trade secrets and proprietary information, and in these cases, we would not be able to assert any trade secret rights against those parties. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and the failure to obtain or maintain trade secret protection could adversely affect our competitive business position.

In addition, the laws of some countries do not protect intellectual property and other proprietary rights to the same extent as the laws of the United States. To the extent we expand into international activities, our exposure to unauthorized copying, transfer and use of our proprietary technology or information may increase.

Our means of protecting our intellectual property and proprietary rights may not be adequate or our competitors could independently develop similar technology. If we fail to meaningfully protect our intellectual property and proprietary rights, our business, results of operations and financial condition could be adversely affected.

Assertions by third parties of infringement or other violations by us of its intellectual property rights could result in significant costs and harm our business and operating results.

Our success depends upon our ability to refrain from infringing upon the intellectual property rights of others. Some companies, including some of our competitors, own large numbers of patents, copyrights and trademarks, which they may use to assert claims against us. As we grow and enter new markets, we will face a growing number of competitors. As the number of competitors in our industry grows and the functionality of products in different industry segments overlaps, we expect that software and other solutions in our industry may be subject to such claims by third parties. Third parties may in the future assert claims of infringement, misappropriation or other violations of intellectual property rights against us. We cannot assure investors that infringement claims will not be asserted against us in the future, or that, if asserted, any infringement claim will be successfully defended. A successful claim against us could require that we pay substantial damages or ongoing royalty payments, prevent us from offering our products and services, or require that we comply with other unfavorable terms. We may also be obligated to indemnify our customers or business partners or pay substantial settlement costs, including royalty payments, in connection with any such claim or litigation and to obtain licenses, modify applications or refund fees, which could be costly. Even if we were to prevail in such a dispute, any litigation regarding our intellectual property could be costly and time-consuming and divert the attention of our management and key personnel from our business operations.

Certain of our core technology is licensed, and that license may be terminated if we were to breach our obligations under the license.

The initial work on our core technology is derived from work done by our founders while at the University of Iowa, around which there is currently a family of patent applications, the rights of which are owned by the University of Iowa Research Foundation (UIRF) and exclusively licensed to us. In addition, certain follow-on work on our core technology also is derived from work done by our founders while at the University of Iowa but was furthered by our founders. Therefore, certain follow-on work is co-owned by UIRF and us, and exclusively licensed to us under the license agreement with UIRF. That license agreement and those licenses granted under the license agreement terminate on the expiration of the patent rights licensed under the license agreement, unless certain proprietary, non-patented technical information is still being used by us, in which case the license agreement will not terminate until the date of termination of such use. The licenses under the license agreement could terminate prior to the expiration of the licensed patent rights if we materially breach our obligations under the license agreement, including failing to pay the applicable license fees and any interest on such fees, and if we fail to fully remedy such breach within the period specified in the license agreement, or if we enter liquidation, have a receiver or administrator appointed over any assets related to the license agreement, or cease to carry on business, or file for bankruptcy or if an involuntary bankruptcy petition is filed against us. The license agreement can also be terminated by either party as a result of any material breach of the license which is not remedied within 30 days after receiving written notice thereof or by UIRF as a result of any breach of the license which has not been cured within 90 days after UIRF provides written notice of such breach.

Some of our technologies incorporate “open-source” software or other similar licensed technologies, which could become unavailable or subject us to increased costs, delays in production or assessment or litigation.

In order to provide our products, we currently use a variety of technologies including, for example, genotyping, digital methylation assessment and data processing technologies owned by third parties. The terms of these agreements, and any other “open source” software agreements we may rely upon in the future, are subject to change without notice and may increase our costs. Moreover, our failure to comply with the terms of one or more of these agreements could expose us to business disruption because the license may be terminated automatically due to non-compliance.

The use and distribution of open-source software may also entail greater risks than the use of third-party commercial software, as open-source licensors generally do not provide warranties or other contractual protections regarding infringement claims or the quality of the code. Many of the risks associated with use of open-source software cannot be eliminated and could negatively affect our business.

In addition, the wide availability of open-source code used in our current and future products could expose us to security vulnerabilities. From time to time, we may face claims from third parties asserting ownership of, or demanding release of, the open-source software or derivative works that we developed using such software (which could include our proprietary source code), or otherwise seeking to enforce the terms of the applicable open-source license. These claims could result in litigation that could be costly to defend, have a negative effect on our operating results and financial condition or require us to devote additional research and development resources to change our existing or future proprietary source code. Responding to any infringement or noncompliance claim by an open-source vendor, regardless of its validity, discovering certain open-source software code in our products, or a finding that we have breached the terms of an open- source software license, could harm our business, results of operations and financial condition. In each case, we would be required to either seek licenses to software or services from other parties and redesign our products to function with such other parties’ software or services or develop these components internally, which would result in increased costs and could result in delays to product launches. Furthermore, we might be forced to limit the features available in our current or future solutions. If these delays and feature limitations occur, our business, results of operations and financial condition could be adversely affected.

Intellectual property that is in-licensed may have been made using government funding and, thus, may be subject to federal regulations under the Bayh-Dole Act.

The intellectual property Cardio has licensed from UIRF is indicated as having been discovered through government funded programs and thus, may be subject to federal regulations under the Bayh-Dole Act. In general, the Bayh-Dole Act provides the U.S. government certain rights in inventions developed using government funding, such as a right to a non-exclusive, non-transferable, irrevocable worldwide license to use inventions for any governmental purpose. In addition, intellectual property generated with government funding is also subject to certain reporting requirements, and the Bayh-Dole Act requires that any products subject to the Bayh-Dole Act be manufactured substantially in the United States, although this manufacturing requirement can be waived if the owner of the patents and applications can show that reasonable efforts to manufacture the product substantially in the United States were unsuccessful, or that under the circumstances, domestic manufacture is not commercially feasible.

Under the Bayh-Dole Act, the U.S. government has the right to take title to inventions developed using a U.S. government funded program, referred to as “march-in rights,” for a number of reasons including, for example, failure to disclose the invention to the government or failure to file an application within specified time limits. In addition, under the Bayh-Dole Act, the U.S. government has the right to require any invention developed using U.S. government funding to be granted exclusive, partially exclusive, or non-exclusive licenses to any of these inventions to a third party if it determines that (i) adequate steps have not been taken to commercialize the invention (ii) government action is necessary to meet public health or safety needs or (iii) government action is necessary to meet requirements for public use under federal regulations.

Compliance with such regulations may limit Cardio’s exclusive rights, subject Cardio to expenditure of resources with respect to reporting requirements and limit Cardio’s ability to contract with non-U.S. manufacturers. In addition, any exercise by the government of any of the foregoing rights under the Bayh-Dole Act may affect Cardio’s competitive position, business, financial condition, results of operations, and prospects.

Risks Related to Government Regulation

We conduct business in a heavily regulated industry, and if we fail to comply with these laws and government regulations, we could incur penalties or be required to make significant changes to our operations or experience adverse publicity, which could have a material adverse effect on our business, financial condition, and results of operations.

The healthcare industry is heavily regulated and closely scrutinized by federal, state and local governments. Comprehensive statutes and regulations govern the manner in which we provide and bill for our products services and collect reimbursement from governmental programs and private payors, our contractual relationships with providers, vendors and customers, our marketing activities and other aspects of our operations. Of particular importance are:

the federal physician self-referral law, commonly referred to as the Stark Law;

the federal Anti-Kickback Act;

the criminal healthcare fraud provisions of HIPAA;

the federal False Claims Act;

reassignment of payment rules that prohibit certain types of billing and collection;

similar state law provisions pertaining to anti-kickback, self-referral and false claims issues;

state laws that prohibit general business corporations, such as us, from practicing medicine; and

laws that regulate debt collection practices as applied to our debt collection practices.

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our business activities could be subject to challenge under one or more of such laws. Achieving and sustaining compliance with these laws may prove costly. Failure to comply with these laws and other laws can result in civil and criminal penalties such as fines, damages, overpayment recoupment loss of enrollment status and exclusion from the Medicare and Medicaid programs. The risk of us being found in violation of these laws and regulations is increased by the fact that many of them have not been fully interpreted by the regulatory authorities or the courts, and their provisions are sometimes open to a variety of interpretations. Our failure to accurately anticipate the application of these laws and regulations to our business or any other failure to comply with regulatory requirements could create liability for us and negatively affect our business. Any action against us for violation of these laws or regulations, even if we successfully defend against it, could cause us to incur significant legal expenses, divert management’s attention from the operation of our business and result in loss of customers and adverse publicity.

To enforce compliance with the federal laws, the U.S. Department of Justice and the Office of the Inspector General (“OIG”) have recently increased their scrutiny of healthcare providers, which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing with investigations can be time- and resource-consuming and can divert management’s attention from the business. Any such investigation or settlement could increase our costs or otherwise have an adverse effect on our business. In addition, because of the potential for large monetary exposure under the federal False Claims Act, which provides for treble damages and mandatory minimum penalties of $5,500 to $11,000 per false claim or statement, healthcare providers often resolve allegations without admissions of liability for significant and material amounts to avoid the uncertainty of treble damages that may be awarded in litigation proceedings. Such settlements often contain additional compliance and reporting requirements as part of a consent decree, settlement agreement or corporate integrity agreement. Given the significant size of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.

The laws, regulations and standards governing the provision of healthcare services may change significantly in the future. We cannot assure investors that any new or changed healthcare laws, regulations or standards will not materially adversely affect our business. We cannot assure investors that a review of our business by judicial, law enforcement, regulatory or accreditation authorities will not result in a determination that could adversely affect our operations.

If the FDA were to begin actively regulating our tests or software, we could incur substantial costs and delays associated with trying to obtain premarket 510(k) clearance, de novo classification, or premarket approval and incur costs associated with complying with post-market controls.

We believe our Epi+Gen CHD™ and PrecisionCHD™ tests are LDTs. The FDA generally considers an LDT to be a test that is designed, manufactured, and used within a single laboratory that is certified under CLIA and meets the regulatory requirements under CLIA to perform high complexity testing. Our laboratories are currently regulated under CLIA and must comply with CAP requirements, and we are subject to extensive federal and state laws and regulations. The FDA issued a final rule in May 2024 that would have subjected many LDTs to regulatory requirements including, in some cases, premarket authorization. A federal district court vacated the FDA final rule in May 2025, holding that LDTs are not subject to FDA regulation. The FDA rescinded the final rule in September 2025. The FDA has not indicated how it will interpret the court ruling or whether it will seek a different regulatory approach with respect to LDTs or components thereof. In June 2025, Congress re-introduced the Verifying Accurate, Leading-edge IVCT Development Act (“VALID Act”) to establish a new risk-based regulatory framework for in vitro clinical tests (“IVCTs”), including IVDs, LDTs, collection devices and instruments used with such tests. This legislation was previously introduced in 2021 and 2023.

If the FDA were to develop an alternate approach to regulating LDTs, or if Congress were to enact legislation giving FDA authority to regulate our current or future LDTs, or any components, materials, or software we use in our tests we could be forced to stop selling our tests or be required to modify claims for or make other changes to our tests while we or our suppliers work to comply with FDA requirements including, potentially, premarket authorization. Our business could be adversely affected while such review was ongoing and if we or our supplier were ultimately unable to obtain such authorization. Completing such submissions would require the expenditure of time, attention and financial and other resources, and may not yield the desired results, which could delay, limit or prevent regulatory authorization.

We also believe that our Actionable Clinical Intelligence and HeartRisk platform are not subject to regulation by the FDA.In particular, the Actionable Clinical Intelligence platform is offered as a component of the PrecisionCHD LDT which, as noted above, FDA does not have authority to regulate. HeartRisk is intended for use by business leaders as a population health analytics platform and as such does not meet the device definition. If the FDA were to disagree with our position, this could have an adverse impact on our ability to offer our tests and related services. If the FDA required us to obtain marketing authorization for one or more of our platforms, our business could be adversely affected while such review was in process or if we are unable to obtain marketing authorization.

If our products do not receive adequate coverage and reimbursement from third-party payors, our ability to expand access to our tests beyond the initial sales channels will be limited and our overall commercial success will be limited.

We currently do not have broad-based coverage and reimbursement for the Epi+Gen CHD™ and PrecisionCHD™ tests. However, our strategy is to expand access to our tests by pursuing coverage and reimbursement by third-party payors, including government payors. Coverage and reimbursement by third-party payors, including managed care organizations, private health insurers, and government healthcare programs, such as Medicare and Medicaid in the United States and similar programs in other countries, for the types of risk assessment and detection tests we perform can be limited and uncertain. Healthcare providers may not order our products unless third-party payors cover and provide adequate reimbursement for a substantial portion of the price of the products. If we are not able to obtain adequate coverage and an acceptable level of reimbursement for our products from third-party payors, there could be a greater co-insurance or co-payment obligation for any individual for whom a test is ordered. The individual may be forced to pay the entire cost of a test out-of-pocket, which could dissuade physicians from ordering our products and, if ordered, could result in delay in or decreased likelihood of collection of payment.

Medicare is the single largest U.S. payor and a particularly important payor for many cardiac-related laboratory services, given the demographics of the Medicare population. Generally, traditional Medicare fee-for-service will not cover screening tests that are performed in the absence of signs, symptoms, complaints, personal history of disease, or injury except when there is a statutory provision that explicitly covers the test. Epi+Gen CHD™ could be considered a screening test under Medicare and, accordingly, may not be eligible for traditional Medicare fee-for- service coverage and reimbursement unless we pursue substantial additional measures, which would require significant investments, and may ultimately be unsuccessful or may take several years to achieve.

If eligible for reimbursement, laboratory tests such as ours generally are classified for reimbursement purposes under CMS’s Healthcare Common Procedure Coding System (“HCPCS”) and the American Medical Association’s (“AMA”) Current Procedural Terminology (“CPT”) coding systems. We and payors must use those coding systems to bill and pay for our diagnostic tests, respectively. These HCPCS and CPT codes are associated with the particular product or service that is provided to the individual. Accordingly, without a HCPCS or CPT code applicable to our products, the submission of claims could be a significant challenge. Once CMS creates an HCPCS code or the AMA establishes a CPT code, CMS establishes payment rates and coverage rules under traditional Medicare, and private payors establish rates and coverage rules independently. Under Medicare, payment for laboratory tests is generally made under the Clinical Laboratory Fee Schedule (“CLFS”) with payment amounts assigned to specific HCPCS and CPT codes. In addition, laboratory-reported private payor rates are used to establish Medicare payment rates for tests reimbursed via the CLFS. This methodology implements Section 216 of the Protecting Access to Medicare Act of 2014 (“PAMA”) and requires laboratories that meet certain requirements related to volume and type of Medicare revenues to report to CMS their private payor payment rates for each test they perform, the volume of tests paid at each rate, and the HCPCS code associated with the test. CMS uses the reported information to set the Medicare payment rate for each test at the weighted median private payor rate. The full impact of the PAMA rate-setting methodology and its applicability to our products remains uncertain at this time.

Coverage and reimbursement by a third-party payor may depend on a number of factors, including a payor’s determination that a product is appropriate, medically necessary, and cost- effective. Each payor will make its own decision as to whether to establish a policy or enter into a contract to cover our products and the amount it will reimburse for such products. Obtaining approvals from third-party payors to cover our products and establishing adequate coding recognition and reimbursement levels is an unpredictable, challenging, time-consuming, and costly process, and we may never be successful. If third-party payors do not provide adequate coverage and reimbursement for our products, our ability to succeed commercially will be limited.

Even if we establish relationships with payors to provide our products at negotiated rates, such agreements would not obligate any healthcare providers to order our products or guarantee that we would receive reimbursement for our products from these or any other payors at adequate levels. Thus, these payor relationships, or any similar relationships, may not result in acceptable levels of coverage and reimbursement for our products or meaningful increases in the number of billable tests we sell to healthcare providers. We believe it may take at least several years to achieve coverage and adequate reimbursement with a majority of third-party payors, including with those payors offering negotiated rates. In addition, we cannot predict whether, under what circumstances, or at what payment levels payors will cover and reimburse for our products. We do not expect Epi+Gen CHD™ or PrecisionCHD™ to have Medicare or other third-party coverage or reimbursement in the near term. However, if we fail to establish and maintain broad-based coverage and reimbursement for our products, our ability to expand access to our products, generate increased revenue, and grow our test volume and customer base will be limited, and our overall commercial success will be limited.

Our products may fail to achieve the degree of market acceptance necessary for commercial success.

The failure of our products, once introduced, to be listed in physician guidelines or of our studies to produce favorable results or to be published in peer-reviewed journals could limit the adoption of our products. In addition, healthcare providers and third-party payors, including Medicare, may rely on physician guidelines issued by industry groups, medical societies, and other key organizations, before utilizing or reimbursing the cost of any diagnostic or screening test. Although we have published a study showing the Epi+Gen CHD™ and PrecisionCHD™ tests are associated with cost saving, it is not yet, and may never be, listed in any such guidelines.

Further, if our products or the technology underlying them do not receive sufficient favorable exposure in peer-reviewed publications, the rate of physician and market acceptance of our products and positive reimbursement coverage decisions for our products could be negatively affected. The publication of clinical data in peer-reviewed journals is an important step in commercializing and obtaining reimbursement for products, such as Epi+Gen CHD™ and PrecisionCHD™, and our inability to control when, if ever, results are published may delay or limit our ability to derive sufficient revenues from any product that is developed using data from a clinical study.

Failure to achieve broad market acceptance of our products, including Epi+Gen CHD™ and PrecisionCHD™, would materially harm our business, financial condition, and results of operations.

Risks Related to Customer Privacy, Cybersecurity and Data

Our use and disclosure of personally identifiable information, including health information, is subject to federal and state privacy and security regulations, and our failure to comply with those regulations or to adequately secure the information we hold could result in significant liability or reputational harm and, in turn, a material adverse effect on our customer base and revenue.

Numerous state and federal laws and regulations govern the collection, dissemination, use, privacy, confidentiality, security, availability and integrity of Personally Identifiable Information (“PII”), including protected health information. These laws and regulations include the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”). HIPAA establishes a set of basic national privacy and security standards for the protection of protected health information, (“PHI”), by health plans, healthcare clearinghouses and certain healthcare providers, referred to as covered entities, and the business associates with whom such covered entities contract for services, which includes Cardio.

HIPAA requires healthcare providers like Cardio to develop and maintain policies and procedures with respect to PHI that is used or disclosed, including the adoption of administrative, physical and technical safeguards to protect such information. HIPAA also implemented the use of standard transaction code sets and standard identifiers that covered entities must use when submitting or receiving certain electronic healthcare transactions, including activities associated with the billing and collection of healthcare claims.

HIPAA imposes mandatory penalties for certain violations. Penalties for violations of HIPAA and its implementing regulations start at $100 per violation and are not to exceed $50,000 per violation, subject to a cap of $1.5 million for violations of the same standard in a single calendar year. However, a single breach incident can result in violations of multiple standards. HIPAA also authorizes state attorneys general to file suit on behalf of their residents. Courts will be able to award damages, costs and attorneys’ fees related to violations of HIPAA in such cases. While HIPAA does not create a private right of action allowing individuals to sue us in civil court for violations of HIPAA, its standards have been used as the basis for duty of care in state civil suits such as those for negligence or recklessness in the misuse or breach of PHI.

In addition, HIPAA mandates that the Secretary of Health and Human Services, or HHS, conduct periodic compliance audits of HIPAA-covered entities or business associates for compliance with the HIPAA Privacy and Security Standards. It also tasks HHS with establishing a methodology whereby harmed individuals who were the victims of breaches of unsecured PHI may receive a percentage of the Civil Monetary Penalty fine paid by the violator.

HIPAA further requires that patients be notified of any unauthorized acquisition, access, use or disclosure of their unsecured PHI that compromises the privacy or security of such information, with certain exceptions related to unintentional or inadvertent use or disclosure by employees or authorized individuals. HIPAA specifies that such notifications must be made “without unreasonable delay and in no case later than 60 calendar days after discovery of the breach.” If a breach affects 500 patients or more, it must be reported to HHS without unreasonable delay, and HHS will post the name of the breaching entity on its public web site. Breaches affecting 500 patients or more in the same state or jurisdiction must also be reported to the local media. If a breach involves fewer than 500 people, the covered entity must record it in a log and notify HHS at least annually.

Numerous other federal and state laws protect the confidentiality, privacy, availability, integrity and security of personally identifiable information, or PII, including PHI. These laws in many cases are more restrictive than, and may not be preempted by, the HIPAA rules and may be subject to varying interpretations by courts and government agencies, creating complex compliance issues for us, and our customers and potentially exposing us to additional expense, adverse publicity and liability.

New health information standards, whether implemented pursuant to HIPAA, congressional action or otherwise, could have a significant effect on the manner in which we must handle healthcare related data, and the cost of complying with standards could be significant. If we do not comply with existing or new laws and regulations related to PHI, it could be subject to criminal or civil sanctions.

Because of the extreme sensitivity of the PII that we store and transmit, the security features of our technology platform are very important. If our security measures, some of which are managed by third parties, are breached or fail, unauthorized persons may be able to obtain access to sensitive customer and patient data, including HIPAA-regulated PHI. As a result, our reputation could be severely damaged, adversely affecting customer and patient confidence. Customers may curtail their use of or stop using our services or our customer base could decrease, which would cause our business to suffer. In addition, we could face litigation, damages for contract breach, penalties and regulatory actions for violation of HIPAA and other applicable laws or regulations and significant costs for remediation, notification to individuals and for measures to prevent future occurrences. Any potential security breach could also result in increased costs associated with liability for stolen assets or information, repairing system damage that may have been caused by such breaches, incentives offered to customers or other business partners in an effort to maintain our business relationships after a breach and implementing measures to prevent future occurrences, including organizational changes, deploying additional personnel and protection technologies, training employees and engaging third-party experts and consultants. While we maintain insurance covering certain security and privacy damages and claims expenses, we may not carry insurance or maintain coverage sufficient to compensate for all liability and in any event, insurance coverage would not address the reputational damage that could result from a security incident.

We outsource important aspects of the storage and transmission of customer and customer personnel information, and thus rely on third parties to manage functions that have material cyber- security risks. We attempt to address these risks by requiring outsourcing subcontractors who handle customer and customer personnel information to sign business associate agreements contractually requiring those subcontractors to adequately safeguard personal health data to the same extent that applies to us and in some cases by requiring such outsourcing subcontractors to undergo third-party security examinations. In addition, we periodically hire third-party security experts to assess and test our security posture. However, we cannot assure investors that these contractual measures and other safeguards will adequately protect us from the risks associated with the storage and transmission of client and patient’s proprietary and protected health information.

In addition, U.S. states are adopting new laws or amending existing laws and regulations, requiring attention to frequently changing regulatory requirements applicable to data related to individuals. For example, California has enacted the California Consumer Privacy Act (“CCPA”). The CCPA gives California residents expanded rights to access and delete their personal information, opt out of certain personal information sharing and receive detailed information about how their personal information is used by requiring covered companies to provide new disclosures to California consumers (as that term is broadly defined and which can include any of our current or future employees who may be California residents or any other California residents whose data we collect or process) and provide such residents new ways to opt out of certain sales of personal information. The CCPA provides for civil penalties for violations, as well as a private right of action for data breaches that is expected to increase data breach litigation. As we expand our operations and customer base, the CCPA may increase our compliance costs and potential liability. Additionally, the California Privacy Rights Act (“CPRA”), which was approved by California voters in the election in November 2020, created obligations relating to consumer data with implementing regulations that, although delayed, did take effect during 2024. The CPRA modifies the CCPA significantly, potentially resulting in further uncertainty and requiring us to incur additional costs and expenses in an effort to comply. Additionally, about 20 U.S. states have adopted, privacy-focused legislation such as Colorado, Virginia, Utah and Connecticut. Aspects of these state laws remain unclear, resulting in further uncertainty and potentially requiring us to modify our data practices and policies and to incur substantial additional costs and expenses in an effort to comply.

Privacy and data security laws and regulations could require us to make changes to our business, impose additional costs on us and reduce the demand for our tests and services.

Our business model contemplates that we will store, process and transmit both public data and our customers’ and customer personnel’s private data. Our customers may store and/or transmit a significant amount of personal or identifying information through our platform. Privacy and data security have become significant issues in the United States and in other jurisdictions where we may offer our solutions. The regulatory framework relating to privacy and data security issues worldwide is evolving rapidly and is likely to remain uncertain for the foreseeable future. Federal, state and foreign government bodies and agencies have in the past adopted, or may in the future adopt, laws and regulations regarding the collection, use, processing, storage and disclosure of personal or identifying information obtained from customers and other individuals. In addition to government regulation, privacy advocates and industry groups may propose various self- regulatory standards that may legally or contractually apply to our business. Because the interpretation and application of many privacy and data security laws, regulations and applicable industry standards are uncertain, it is possible that these laws, regulations and standards may be interpreted and applied in a manner inconsistent with our existing privacy and data management practices. As we expand into new jurisdictions or verticals, we will need to understand and comply with various new requirements applicable in those jurisdictions or verticals.

To the extent applicable to our business or the businesses of our customers, these laws, regulations and industry standards could have negative effects on our business, including by increasing our costs and operating expenses, and delaying or impeding our deployment of new core functionality and products. Compliance with these laws, regulations and industry standards requires significant management time and attention, and failure to comply could result in negative publicity, subject us to fines or penalties or result in demands that we modify or cease existing business practices. In addition, the costs of compliance with, and other burdens imposed by, such laws, regulations and industry standards may adversely affect our customers’ ability or desire to collect, use, process and store personal information using our solutions, which could reduce overall demand for them. Even the perception of privacy and data security concerns, whether or not valid, may inhibit market acceptance of our solutions in certain verticals. Furthermore, privacy and data security concerns may cause our customers’ customers, vendors, employees and other industry participants to resist providing the personal information necessary to allow our customers to use our applications effectively. Any of these outcomes could adversely affect our business and operating results.

General Risks Affecting Our Company

A pandemic, epidemic or outbreak of an infectious disease in the United States or worldwide, including the re-emergence of the novel strain of coronavirus disease, COVID-19, could adversely affect our business.

If a pandemic, epidemic or outbreak of an infectious disease occurs in the United States or worldwide, our business may be adversely affected. If the COVID-19 virus and its potentially more contagious variants cause an additional resurgence of infection of COVID-19, or if new variants continue to develop resistance to government approved COVID-19 vaccinations, or if an influenza or other pandemic were to occur, our business, results of operations, financial condition and liquidity could be negatively impacted.

As a result of public health emergencies, we experienced, and in the future could experience, supply chain disruptions, including shortages, delays and work stoppages among some vendors and suppliers, travel restrictions and cancellation of events, among other effects, thereby significantly and negatively impacting our operations. In addition, our results and financial condition may be adversely affected by future federal or state laws, regulations, orders, or other governmental or regulatory actions addressing public health emergencies such as a COVID-19 or the U.S. health care system, which, if adopted, could result in direct or indirect restrictions to its business, financial condition, results of operations and cash flow.

Changes in accounting standards and subjective assumptions, estimates and judgments by management related to complex accounting matters could significantly affect our financial results or financial condition.

Generally accepted accounting principles and related accounting pronouncements, implementation guidelines and interpretations with regard to a wide range of matters that are relevant to our business, including but not limited to revenue recognition, allowance for doubtful accounts, content asset amortization policy, valuation of our Common Stock, stock-based compensation expense and income taxes, are highly complex and involve many subjective assumptions, estimates and judgments. Changes in these rules or their interpretation or changes in underlying assumptions, estimates or judgments could significantly change or increase volatility of our reported or expected financial performance or financial condition. Refer to Note 2, “Summary of Significant Accounting Policies” to the Audited Financial Statements included elsewhere in this Annual Report on Form 10-K for a description of recent accounting pronouncements.

Risks Related to Our Securities

We are an “emerging growth company” and “smaller reporting company” within the meaning of the Securities Act, and if we take advantage of certain exemptions from disclosure requirements available to emerging growth companies, it could make our securities less attractive to investors and may make it more difficult to compare our performance to the performance of other public companies.

We are an “emerging growth company” as defined in Section 2(a)(19) of the Securities Act, as modified by the Jumpstart our Business Startups Act (the “JOBS Act”). As such, we are eligible for and take advantage of certain exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies for as long as we continue to be an emerging growth company, including, but not limited to, (a) not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley”), (b) reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and (c) exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. As a result, our stockholders may not have access to certain information they may deem important. We will remain an emerging growth company until December 31, 2026, which is the last day of the fiscal year following the fifth anniversary of the date of the first sale of Common Stock in Mana’s initial public offering. We cannot predict whether investors have found or will continue to find our securities less attractive because it will rely on these exemptions. If some investors find our securities less attractive as a result of our reliance on these exemptions, the trading prices of our securities may be lower than they otherwise would be, there may be a less active trading market for our securities and the trading prices of our securities may be more volatile.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. We have elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of our financial statements with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. However, once we lose emerging growth company status on December 31, 2026, we will lose this exemption and will be required to adopt revised or new accounting standards on the time schedule applicable to non-emerging growth companies.

Additionally, we are a “smaller reporting company” as defined in Item 10(f)(1) of Regulation S-K and a non-accelerated filer. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements and reduced executive compensation disclosure. In addition, as a non-accelerated filer and smaller reporting company, we will continue to be exempt from complying with the auditor attestation requirements of Section 404 of Sarbanes-Oxley. We expect that we will remain a smaller reporting company until the last day of any fiscal year for so long as either (a) the market value of our Common Stock held by non-affiliates does not equal or exceed $250 million as of the prior June 30th, or (b) our annual revenues did not equal or exceed $100 million during such completed fiscal year and the market value of our Common Stock held by non-affiliates did not equal or exceed $700 million as of the prior June 30th. To the extent we take advantage of such reduced disclosure obligations, it may also make comparison of our financial statements with other public companies difficult or impossible.

Our stock price may be volatile and may decline regardless of our operating performance.

The market price of our Common Stock may fluctuate significantly in response to numerous factors and may continue to fluctuate for these and other reasons, many of which are beyond our control, including:

actual or anticipated fluctuations in our revenue and results of operations;

failure of securities analysts to maintain coverage of the Company, changes in financial estimates or ratings by any securities analysts who follow us or our failure to meet these estimates or the expectations of investors;

announcements by us or our competitors of significant technical innovations, acquisitions, strategic partnerships, joint ventures, results of operations or capital commitments;

changes in operating performance and stock market valuations of other healthcare-related companies generally, or those in the medical diagnostics industry in particular;

price and volume fluctuations in the overall stock market, including as a result of trends in the economy as a whole;

trading volume of our Common Stock;

the inclusion, exclusion or removal of our Common Stock from any indices;

changes in the Board or management;

transactions in our Common Stock by directors, officers, affiliates and other major investors;

lawsuits threatened or filed against us;

changes in laws or regulations applicable to our business;

changes in our capital structure, such as future issuances of debt or equity securities;

short sales, hedging and other derivative transactions involving our capital stock;

general economic conditions in the United States;

pandemics or other public health crises, including, but not limited to, the COVID-19 pandemic (including additional variants such as the Omicron variant);

other events or factors, including those resulting from war, incidents of terrorism or responses to these events; and

the other factors described in this “Risk Factors” section.

The stock market generally, as well as our Common Stock in particular, have recently experienced extreme price and volume fluctuations. The market prices of securities of companies have experienced fluctuations that often have been unrelated or disproportionate to their operating results. In the past, stockholders have sometimes instituted securities class action litigation against companies following periods of volatility in the market price of their securities. Any similar litigation against us could result in substantial costs, divert management’s attention and resources, and harm its business, financial condition, and results of operations.

An active trading market for our Common Stock may not be created or sustained.

We have listed our Common Stock and Warrants on Nasdaq under the symbols “CDIO” and “CDIOW,” respectively. We cannot assure you that an active trading market for our Common Stock can be sustained. Accordingly, we cannot assure you of the liquidity of any trading market, your ability to sell your shares of our Common Stock when desired or the prices that you may obtain for your shares.

Future sales of Common Stock in the public market could cause our share price to decline significantly, even if our business is doing well.

We have filed, and the SEC has declared effective, registration statements covering (i) the resale of Common Stock underlying Public Warrants issued in the Company’s initial public offering and a substantial number of shares of Common Stock and shares underlying warrants issued in private placements we completed prior to our Business Combination; (ii) up to $17 million in securities on a shelf registration statement that was used for an at-the-market offering of up to $17 million; (iii) up to $9,476,508 in securities on a shelf registration statement that we are currently using for an at-the-market offering of up to $9,476,508; (iii) a registration statement on Form S-8 covering our 2022 Equity Incentive Plan. Public sales of securities can continue to be made under these registration statements, and (iv) a registration statement covering the resale of Common Stock and shares underlying warrants that were sold in a private placement effected in February 2024. In addition, all of the shares we issued in the Business Combination to holders of Legacy Cardio securities are available for resale under Rule 144 without restriction, subject to certain limitations that apply to our affiliates.

The total number of shares available for resale under these registration statements and/or under Rule 144 represents a significant percentage of our outstanding shares. The resale, or expected or potential resale, of a substantial number of our shares of Common Stock in the public market could adversely affect the market price for our shares of Common Stock and make it more difficult for investors to sell their shares of Common Stock at times and prices that they feel are appropriate. In particular, we expect that, because there are a substantial number of shares registered pursuant to various registration statements, the applicable selling securityholders can continue to offer such covered securities for a significant period of time, the precise duration of which cannot be predicted. Accordingly, the adverse market and price pressures resulting from an offering pursuant to a registration statement or Rule 144 may continue for an extended period of time.

Sales of Common Stock pursuant to these registration statements or pursuant to Rule 144 may make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. These sales also could cause the trading price of our Common Stock to fall and make it more difficult for investors to sell shares of our Common Stock at a time and price that they deem appropriate.

If securities or industry analysts either do not publish research about us or publish inaccurate or unfavorable research about us, our business, or our market, or if they change their recommendations regarding our Common Stock adversely, the trading price or trading volume of our Common Stock could decline.

The trading market for our Common Stock is influenced in part by the research and reports that securities or industry analysts may publish about us, our business, our market, or our competitors. If one or more of the analysts initiate research with an unfavorable rating or downgrade our Common Stock, provide a more favorable recommendation about our competitors, or publish inaccurate or unfavorable research about our business, the trading price of our Common Stock would likely decline. In addition, we currently expect that securities research analysts will establish and publish their own periodic projections for our business. These projections may vary widely and may not accurately predict the results we actually achieve. Our stock price may decline if our actual results do not match the projections of these securities research analysts. Furthermore, if no analysts commence coverage of our Company, the trading price and volume for our Common Stock could be adversely affected. If any analyst who may cover us were to cease coverage of the Company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause the trading price or trading volume of our Common Stock to decline.

Delaware law and provisions in our Charter and Bylaws could make a merger, tender offer, or proxy contest difficult, thereby depressing the trading price of our Common Stock.

Our Charter and Bylaws contain provisions that could depress the trading price of our Common Stock by acting to discourage, delay, or prevent a change of control of the Company or changes in our management that our stockholders may deem advantageous. These provisions include the following:

the right of the board of directors to establish the number of directors and fill any vacancies and newly created directorships;

director removal solely for cause;

“blank check” preferred stock that the Board could use to implement a stockholder rights plan;

the right of the Board to issue our authorized but unissued Common Stock and preferred stock without stockholder approval;

no ability of our stockholders to call special meetings of stockholders;

no right of our stockholders to act by written consent, which requires all stockholder actions to be taken at a meeting of our stockholders;

limitations on the liability of, and the provision of indemnification to, our director and officers;

the right of the board of directors to make, alter, or repeal the Bylaws; and

advance notice requirements for nominations for election to the Board or for proposing matters that can be acted upon by stockholders at annual stockholder meetings.

Any provision of the Charter or Bylaws that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our Common Stock, and could also affect the price that some investors are willing to pay for our Common Stock.

Our Bylaws provide that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between the Company and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with the Company or our directors, officers or employees.

The Bylaws provide that the Court of Chancery of the State of Delaware is the exclusive forum for any derivative action or proceeding brought on our behalf, any action asserting a breach of fiduciary duty, any action asserting a claim against us arising pursuant to the DGCL, the Charter or Bylaws or any action asserting a claim against us that is governed by the internal affairs doctrine. These choice of forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees and may discourage these types of lawsuits. This provision would not apply to claims brought to enforce a duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. The Bylaws provide further that, to the fullest extent permitted by law, the federal district courts of the United States will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. However, Section 22 of the Securities Act provides that federal and state courts have concurrent jurisdiction over lawsuits brought under the Securities Act or the rules and regulations thereunder. To the extent the exclusive forum provision restricts the courts in which claims arising under the Securities Act may be brought, there is uncertainty as to whether a court would enforce such a provision. We note that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. Furthermore, the enforceability of similar choice of forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or unenforceable. While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may nevertheless seek to bring a claim in a venue other than those designated in the exclusive forum provisions, and there can be no assurance that such provisions will be enforced by a court in those other jurisdictions. If a court were to find the exclusive-forum provision contained in the Bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business.

We do not intend to pay dividends for the foreseeable future.

We currently intend to retain any future earnings to finance the operation and expansion of our business and we do not expect to declare or pay any dividends in the foreseeable future.

Moreover, the terms of any revolving credit facility into which we or any of our subsidiaries enters may restrict our ability to pay dividends, and any additional debt we or any of our subsidiaries may incur in the future may include similar restrictions. As a result, stockholders must rely on sales of their Common Stock after price appreciation as the only way to realize any future gains on their investment.

We may issue additional shares of our Common Stock or other equity securities without your approval, which would dilute your ownership interests and may depress the market price of our Common Stock.

On January 26, 2024, the Company entered into an At-the-Market Issuance Sales Agreement (the “Sales Agreement”) with Craig-Hallum Capital Group LLC (“Craig-Hallum”). Sales of our Common Stock pursuant to the Sales Agreement were made under the Company’s Registration Statement on Form S-3 filed on January 26, 2024 (File No. 333-276725) declared effective by the SEC on February 1, 2024 and have been, and may continue to be made, under the Company’s Registration Statement on Form S-3 filed on February 7, 2025 (File No. 333-284775) declared effective by the SEC on February 14, 2025. As of March 13, 2026, we have sold 2,251,181 shares of our Common Stock under the Sales Agreement and may sell up to another $5,298,889 of our Common Stock through Craig-Hallum under the Sales Agreement.

As of March 13, 2026, we have Warrants outstanding to purchase 284,292 shares of our Common Stock. We will also have the ability to initially issue an aggregate of 239,920 shares of our Common Stock under the Cardio Equity Incentive Plan, of which 144,320 options have been granted and are currently exercisable and 14,972 RSUs have been granted. To the extent Warrants and options are exercised, and RSUs vest, additional shares of Common Stock could be issued, which will result in dilution to our then existing stockholders and increase the number of shares eligible for resale in the public market. Sales of substantial numbers of such shares in the public market could depress the market price of our Common Stock.

We may issue additional shares of our Common Stock or other equity securities of equal or senior rank in the future in connection with, among other things, future acquisitions or repayment of outstanding indebtedness, without stockholder approval, in a number of circumstances.

The issuance of additional shares of Common Stock or other equity securities of equal or senior rank would have the following effects:

our existing stockholders’ proportionate ownership interest in the Company will decrease;

the amount of cash available per share, including for payment of dividends (if any) in the future, may decrease;

the relative voting strength of each previously outstanding share of Common Stock may be diminished; and

the market price of our shares of Common Stock may decline.

We may redeem the Public Warrants and the Sponsor Warrants prior to their exercise at a time that is disadvantageous to you, as a warrant holder, thereby making your Public Warrants or Sponsor Warrants worthless.

We have the ability to redeem outstanding Public Warrants and Sponsor Warrants at any time after they become exercisable and prior to their expiration, at a price of $0.01 per warrant, provided that the last reported sales price of our Common Stock equals or exceeds $540.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30 trading-day period ending on the third trading day prior to the date on which we give proper notice of such redemption and provided certain other conditions are met. Trading prices of our Common Stock have not historically exceeded the $540.00 per share redemption threshold. If and when the Public Warrants and Sponsor Warrants become redeemable, we may not exercise our redemption right unless there is a current registration statement in effect with respect to the shares of Common Stock underlying the Warrants. While we have registered the Common Stock issuable upon the exercise of the Public Warrants and Sponsor Warrants on a separate registration statement, most recently updated by Post-Effective Amendment No. 3, which the SEC declared effective on September 9, 2025, it must remain current and effective by future filings. There can be no assurance that the registration statement will still be effective at the time that we would like to exercise our redemption rights.

In the event we have determined to redeem the Public Warrants and the Sponsor Warrants, holders would be notified of such redemption as described in the Warrant Agreement. Specifically, we would be required to fix a date for the redemption (the “Redemption Date”). Notice of redemption would be mailed by first class mail, postage prepaid, by the Company not less than 30 days prior to the Redemption Date to the registered holders of the Public Warrants and the Sponsor Warrants to be redeemed at their last addresses as they appear on the registration books. In addition, beneficial owners of the redeemable Public Warrants and the Sponsor Warrants will be notified of such redemption via the Company’s posting of the redemption notice to DTC. Redemption of the Public Warrants and the Sponsor Warrants could force you (i) to exercise your Public Warrants and the Sponsor Warrants and pay the exercise price therefor at a time when it may be disadvantageous for you to do so, (ii) to sell your Public Warrants and the Sponsor Warrants at the then-current market price when you might otherwise wish to hold your Public Warrants and the Sponsor Warrants or (iii) to accept the nominal redemption price which, at the time the outstanding Public Warrants and the Sponsor Warrants are called for redemption, is likely to be substantially less than the market value of your Public Warrants and the Sponsor Warrants. None of the Private Placement Warrants will be redeemable.

Exercise of our Warrants is dependent upon the trading price of our Common Stock. Because of the disparity between the current stock price and the respective Warrant exercise prices, the Warrants may never be in the money and may expire worthless.

The exercise prices of our currently outstanding Warrants range from a high of $345 to a low of $53.4 per share. We believe the likelihood that warrant holders will exercise the Warrants, and therefore, the amount of cash proceeds that we would receive, is dependent upon the trading price of our Common Stock, the last reported sales price for which was $4.76 per share on March 11, 2026. If the trading price for our Common Stock is less than the applicable exercise price of our Warrants, we believe holders of those Warrants will be unlikely to exercise their Warrants.

There is no guarantee that the Warrants will be in the money prior to their expiration, and, as such, the Warrants may expire worthless, and we may receive no proceeds from the exercise of the Warrants.

The Warrant Agreement designates the courts of the State of New York or the United States District Court for the Southern District of New York as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by holders of the Warrants, which could limit the ability of warrant holders to obtain a favorable judicial forum for disputes with our Company.

The Warrant Agreement provides that, subject to applicable law, (i) any action, proceeding or claim against us arising out of or relating in any way to the Warrant Agreement, including under the Securities Act, will be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York, and (ii) that we irrevocably submit to such jurisdiction, which jurisdiction shall be the exclusive forum for any such action, proceeding or claim. We will waive any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum. Notwithstanding the foregoing, these provisions of the Warrant Agreement will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal district courts of the United States of America are the sole and exclusive forum.

Any person or entity purchasing or otherwise acquiring any interest in Warrants shall be deemed to have notice of and to have consented to the forum provisions in the Warrant Agreement. If any action, the subject matter of which is within the scope the forum provisions of the Warrant Agreement, is filed in a court other than a court of the State of New York or the United States District Court for the Southern District of New York (a “foreign action”) in the name of any holder of Warrants, such holder shall be deemed to have consented to: (x) the personal jurisdiction of the state and federal courts located in the State of New York in connection with any action brought in any such court to enforce the forum provisions (an “enforcement action”), and (y) having service of process made upon such warrant holder in any such enforcement action by service upon such warrant holder’s counsel in the foreign action as agent for such warrant holder.

This choice-of-forum provision may limit a warrant holder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us, which may discourage such lawsuits.

Alternatively, if a court were to find this provision of the Warrant Agreement inapplicable or unenforceable with respect to one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could materially and adversely affect our business, financial condition and results of operations and result in a diversion of the time and resources of our management and board of directors.

Financial reporting obligations of being a public company in the United States are expensive and time-consuming, and our management will be required to devote substantial time to compliance matters.

As a publicly traded company, we will incur significant additional legal, accounting and other expenses that we did not incur as a privately company. The obligations of being a public company in the United States require significant expenditures and will place significant demands on our management and other personnel, including costs resulting from public company reporting obligations under the Exchange Act and the rules and regulations regarding corporate governance practices, including those under Sarbanes-Oxley, the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd Frank”), and the Nasdaq listing requirements. These rules require the establishment and maintenance of effective disclosure and financial controls and procedures, internal control over financial reporting and changes in corporate governance practices, among many other complex rules that are often difficult to implement, monitor and maintain compliance with. Moreover, despite reforms made possible by the JOBS Act, the reporting requirements, rules, and regulations will make some activities more time-consuming and costly, particularly after we are no longer an “emerging growth company.” In addition, we expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance. Our management and other personnel will need to devote a substantial amount of time to ensure that we comply with all of these requirements and to keep pace with new regulations, otherwise we may fall out of compliance and risk becoming subject to litigation or being delisted, among other potential problems.

If we fail to comply with the rules under Sarbanes-Oxley related to accounting controls and procedures in the future, or, if we discover material weaknesses and other deficiencies in our internal control and accounting procedures, our stock price could decline significantly and raising capital could be more difficult.

Section 404 of Sarbanes-Oxley requires annual management assessments of the effectiveness of our internal control over financial reporting. If we fail to comply with the rules under Sarbanes-Oxley related to disclosure controls and procedures in the future, or, if we discover material weaknesses and other deficiencies in our internal control and accounting procedures, our stock price could decline significantly and raising capital could be more difficult. If material weaknesses or significant deficiencies are discovered or if we otherwise fail to achieve and maintain the adequacy of our internal control, we may not be able to ensure that we can conclude on an ongoing basis that we have effective internal controls over financial reporting in accordance with Section 404 of Sarbanes-Oxley. Moreover, effective internal controls are necessary for us to produce reliable financial reports and are important to helping prevent financial fraud. If we cannot provide reliable financial reports or prevent fraud, our business and operating results could be harmed, investors could lose confidence in our reported financial information, and the trading price of our Common Stock could drop significantly.

We have incurred and will continue to incur additional costs to remediate material weaknesses in our internal control over financial reporting, as described in Item 9A. “Controls and Procedures.” The additional reporting and other obligations imposed by these rules and regulations will increase legal and financial compliance costs and the costs of related legal, accounting and administrative activities. These increased costs will require us to divert a significant amount of money that could otherwise be used to expand the business and achieve strategic objectives.

We will need to grow the size of our organization and may experience difficulties in managing this growth.

As our expansion plans and strategies develop, and as we continue to operate as a public company, we expects needing additional managerial, operational, sales, marketing, financial and other personnel. Future growth would impose significant added responsibilities on members of management, including:

identifying, recruiting, compensating, integrating, maintaining and motivating additional employees;

coping with demands on Management related to the increased size of its business;

assimilating different corporate cultures and business practices;

converting other entities’ books and records and conforming their practices to ours;

integrating operating, accounting and information technology systems of other entities with ours and in maintaining uniform procedures, policies and standards, such as internal accounting controls; and

improving our operational, financial and management controls, reporting systems and procedures.

Our future financial performance and our ability to expand our business will depend, in part, on our ability to effectively manage any future growth, and our management may also have to divert a disproportionate amount of its attention away from day-to-day activities in order to devote a substantial amount of time to managing these growth activities.

If we are not able to effectively expand our organization by hiring new employees and expanding our groups of consultants and contractors, we may not be able to successfully implement the tasks necessary to further develop and commercialize our product candidates and, accordingly, may not achieve our research, development and commercialization goals.

There can be no assurance that we will be able to comply with the continued listing standards of Nasdaq, and delisting of our securities could become more likely if a proposed Nasdaq rule currently being considered is adopted, as expected .

Our Common Stock is listed on The Nasdaq Capital Market ("Nasdaq”). In recent years, Nasdaq has adopted, and currently is proposing, revised standards that could make it more difficult for a small company to maintain its listing. In order to maintain our listing, we must satisfy minimum financial and other requirements including, without limitation, a requirement that the closing bid price of our Common Stock be at least $1.00 per share.. Under Nasdaq’s listing rules, if a company’s security fails to meet the continued listing requirement for minimum bid price of no less than $1.00 for 30 consecutive business days, and the Company has effected a reverse stock split over the prior one-year period; or has effected one or more reverse stock splits over the prior two-year period with a cumulative ratio of 250 shares or more to one, then that company loses eligibility for any additional compliance cure period and risks immediate delisting with respect to that security. The Company effected a reverse stock split on May 12, 2025 in order to cure the $1.00 minimum bid deficiency, making these time periods relevant. In addition, Nasdaq has recently proposed a rule change that if a company’s listed securities fail to have a market value of listed securities (“MVLS”) of at least $5 million for 30 consecutive business days, then Nasdaq will immediately suspend that company’s securities, with delisting to follow without Nasdaq’s historically-customary cure period. The only basis of appeal will be to correct calculation errors, and any suspension will remain in effect during that appeal process. The proposal is subject to SEC approval, which is currently expected in March 2026, and would become effective 60 days thereafter. If the proposal is implemented and becomes effective, our securities will be more vulnerable to being delisted if we are unable to maintain a MVLS of at least $5.0 million. On March 11, 2026, our Common Stock closed at $4.76, so we currently have a MVLS above $5.0 million, but our stock is volatile and could be subject to delisting in the future.

If Nasdaq delists our shares of Common Stock and Public Warrants for failure to meet the listing standards, we and our securityholders could face significant material adverse consequences including:

a limited availability of market quotations for our securities;

reduced liquidity for our securities;

a determination that our Common Stock is a “penny stock,” which will require brokers trading in our common stock to adhere to more stringent rules, possibly resulting in a reduced level of trading activity in the secondary trading market for shares of our Common Stock;

a more limited amount of analyst coverage; and

a decreased ability to issue additional securities or obtain additional financing in the future, including that we would no longer be able to rely on our ATM Offering, which has been its primary source of financing for the last two years.

We may acquire other companies or technologies, which could divert our management’s attention, result in dilution to our stockholders and otherwise disrupt our operations and adversely affect our operating results.

We may in the future seek to acquire or invest in businesses, applications and services or technologies that we believe could complement or expand our services, enhance our technical capabilities or otherwise offer growth opportunities. The pursuit of potential acquisitions may divert the attention of management and cause us to incur various expenses in identifying, investigating and pursuing suitable acquisitions, whether or not they are consummated.

In addition, we do not have any experience in acquiring other businesses. If we acquire additional businesses, we may not be able to integrate the acquired personnel, operations and technologies successfully, or effectively manage the combined business following the acquisition. We also may not achieve the anticipated benefits from the acquired business due to a number of factors, including:

inability to integrate or benefit from acquired technologies or services in a profitable manner;

unanticipated costs or liabilities associated with the acquisition;

difficulty integrating the accounting systems, operations, and personnel of the acquired

difficulties and additional expenses associated with supporting legacy products and hosting infrastructure of the acquired business;

difficulty converting the customers of the acquired business onto the Platform and contract terms, including disparities in the revenue, licensing, support, or professional services model of the acquired company;

diversion of management’s attention from other business concerns;

adverse effects to our existing business relationships with business partners and customers as a result of the acquisition;

the potential loss of key employees;

use of resources that are needed in other parts of our business; and

use of substantial portions of our available cash to consummate the acquisition.

In addition, a significant portion of the purchase price of companies we acquire may be allocated to acquired goodwill and other intangible assets, which must be assessed for impairment at least annually. In the future, if our acquisitions do not yield expected returns, we may be required to take charges to our operating results based on this impairment assessment process, which could adversely affect our results of operations.

Acquisitions could also result in dilutive issuances of equity securities or the incurrence of debt, which could adversely affect our operating results. In addition, if an acquired business fails to meet our expectations, our operating results, business and financial position may suffer.

Item 1B. Unresolved Staff Comments

Not applicable.

Item 1C. Cybersecurity

Risk Management and Strategy

We have established policies and processes for assessing, identifying, and managing material risk from cybersecurity threats, and we have integrated these processes into our overall risk management program. We assess material risks from cybersecurity threats, including any potential unauthorized occurrence on or conducted through our information systems that may result in adverse effects on the confidentiality, integrity, or availability of our information systems or any information residing therein.

We have adopted as the governance framework for our cybersecurity program the Service Organization Control Type 2 (“SOC2”) and the Health Insurance Portability and Accountability Act (“HIPAA”). We use this framework as a guide to help us identify, assess, respond to, and manage cybersecurity risks relevant to our business. Our cybersecurity risk management program includes:

•

periodic risk assessments designed to help identify material cybersecurity risks to our critical systems, information, and our broader enterprise information technology environment;

•

skilled information security and data privacy personnel, who support our cybersecurity risk assessment processes, our security controls, and our response to cybersecurity incidents;

•

external service providers, where appropriate, to monitor, assess, test, or otherwise assist with aspects of our security controls, and to support risk mitigation efforts;

•

training for our employees on cybersecurity awareness and the importance of protecting information assets.

•

periodic reviews of key cybersecurity policies, and updating as needed;

•

a cybersecurity incident response plan that includes procedures for responding to cybersecurity incidents.

We have not identified any risks from known cybersecurity threats, including as a result of any prior cybersecurity incidents, that have materially affected or are reasonably likely to materially affect us, including our business strategy, results of operations, or financial condition.

Governance

Our Board considers cybersecurity risk as part of its risk oversight function and management expects to keep the Board informed of any material cybersecurity threats and expects to provide a report to the Board on a periodic basis and the Board will consider and oversee.

Our management team is responsible for assessing and managing our material risks from cybersecurity threats. Our Chief Technology Officer leads a team of information security professionals who have primary responsibility for our overall cybersecurity risk management program and supervises both our internal personnel and our external cybersecurity consultants.

Our management team oversees efforts to prevent, detect, mitigate, and remediate cybersecurity risks and incidents through various means, which may include threat briefings from internal personnel and external service providers, as well as alerts and reports produced by security tools deployed in the information technology environment.

Item 2. Properties

We do not own any real estate or other physical properties materially important to our operations. We currently maintain our principal executive offices at 311 W. Superior Street, Suite 444, Chicago, IL 60654 pursuant to a three-year lease agreement with an unaffiliated third party that commenced on December 1, 2023. The cost for this space is approximately $13,000 per month. We also maintain a laboratory at 2565 N. Dodge, Suite D, Iowa City, IA 52245 pursuant to a five-year lease agreement with an unaffiliated third party that commenced on December 1, 2023. The cost for this space is approximately $8,505 per month. We consider our current office space, combined with the other office space otherwise available to our executive officers, adequate for our current operations.

Item 3. Legal Proceedings

We are not currently a party to any material litigation or other legal proceedings brought against us.

Item 4. Mine Safety Disclosures

Not applicable.

You should read the sections titled “Risk Factors” and “Cautionary Note Regarding Forward Looking Statements” for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis. Our historical results are not necessarily indicative of the results that may be expected for any period in the future.

Unless the context requires otherwise, references to “Cardio,” the “Company,” “we,” “us” and “our” refer to Cardio Diagnostics Holdings, Inc., a Delaware corporation, together with its consolidated subsidiary.

Overview

Cardio was formed to further develop and commercialize a series of products for major types of cardiovascular disease and associated co-morbidities, including coronary heart disease (“CHD”), stroke, heart failure and diabetes, by leveraging our Artificial Intelligence (“AI”)-driven Multi-Omics Engine™. As a company, we aspire to give every American adult insight into their unique risk for various cardiovascular diseases. Cardio aims to become one of the leading medical technology companies for enabling improved prevention, early detection and treatment of cardiovascular disease. Cardio is transforming the approach to cardiovascular disease from reactive to proactive and hope to accelerate the adoption of Precision Medicine for all. We believe that incorporating Cardio’s solutions into routine practice in primary care and prevention efforts can help alter the trajectory that nearly one in two Americans is expected to develop some form of cardiovascular disease by 2035.

Cardio launched its first clinical test, Epi+Gen CHD™, a three-year symptomatic CHD risk assessment clinical blood test targeting CHD events, including heart attacks, in 2021 during the COVID-19 pandemic. As a result, the initial strategy for commercialization involved launching the test via telemedicine and in smaller provider practices such as concierge medicine practices. The volume of tests through these channels were minimal, and as the circumstances around COVID-19 pandemic improved, management re-vamped the Company’s go-to-market strategy to include other healthcare verticals and stakeholders beyond patients and small providers, including larger provider organizations, group purchasing organizations, employers, payors and life insurers. This new approach allowed Cardio to expand the reach of our solutions beyond the initial focus areas. Beyond the launch of Epi+Gen CHD, in March 2023, we announced the launch of our second product, PrecisionCHD™, an integrated epigenetic-genetic clinical blood test for the detection of coronary heart disease. The PrecisionCHD™ tests is coupled to Actionable Clinical Intelligence (“ACI”), a platform that offers new epigenetic and genetic insights to clinicians prescribing the to personalize patient management and help improve chronic care management. In May 2023, we launched CardioInnovate360™, a research-use-only (“RUO”) solution to support the discovery, development and validation of novel biopharmaceuticals for the assessment and management of cardiovascular diseases. In February 2024, we announced the launch of HeartRisk™, a cardiovascular disease risk intelligence platform. We believe that our Epi+Gen CHD™ and PrecisionCHD™ tests are categorized as laboratory-developed tests, or “LDTs.” The new go-to-market strategy is also being implemented for these products. Despite long partnership and sales cycles, in some instance as long as 24 months, Cardio has been able to increase the number of provider organizations offering its tests and has continued the development of a more robust sales and partnership pipeline. In the fiscal year ended December 31, 2025, the focus of the Company remained in driving adoption of our clinical solutions, predominantly among providers, channel partners and employers. In addition, the Company made progress in its ongoing expansion to additional markets domestically and internationally with the first international expansion to India, partnering with channel partners such as YMCA of East Tennessee and Southdale YMCA to offer testing to its members and community, and in setting up our CLIA laboratory facility.

Recent Developments

At the Market Sales Agreement

On January 26, 2024, the Company entered into the Sales Agreement with Craig-Hallum. Pursuant to the Sales Agreement, the Company may sell, at its option, shares of its Common Stock through Craig-Hallum, as sales agent. Sales of the Common Stock were made pursuant to the Sales Agreement initially up to an aggregate of $17 million under the Company’s Registration Statement on Form S-3 filed on January 26, 2024 (File No. 333-276725) and declared effective by the SEC on February 1, 2024 (the “Initial Registration Statement”). Additional sales have been, and may continue to be made, pursuant to the Sales Agreement up to an aggregate of $9,476,508 under the Company’s Registration Statement on Form S-3 filed on February 7, 2025 (File No. 333-284775), declared effective by the SEC on February 14, 2025 (the “Additional Registration Statement”) and its accompanying Prospectus Supplement dated February 14, 2025. Subject to the terms and conditions of the Sales Agreement, Craig-Hallum may sell the shares, if any, only by methods deemed to be an “at the market” offering as defined in Rule 415 promulgated under the Securities Act. The Company has agreed to pay Craig-Hallum a sales commission of 2.5% of the gross proceeds for sales under the Sales Agreement and to provide Craig-Hallum with customary indemnification and contribution rights, including for liabilities under the Securities Act. In addition, the Company is required to reimburse Craig-Hallum for certain specified expenses in connection with entering into the Sales Agreement.

Recent Regulatory and Judicial Developments Regarding LDTs

On May 6, 2024, FDA published a final rule amending the definition of an in vitro diagnostic (“IVD”) device to include tests manufactured by a clinical laboratory. Pursuant to the rule, laboratory developed tests (“LDTs”), i.e., tests designed, manufactured, and used within a single CLIA-certified high complexity laboratory, are medical devices subject to FDA regulation under the Federal Food, Drug, and Cosmetic Act. The final rule also announced FDA’s intention to apply its medical device requirements to LDTs. Under the final rule, all LDTs, unless subject to a specific exemption, would be subject to premarket authorization requirements (510(k), de novo classification, or PMA) for each LDT performed by the laboratory, and to postmarket registration and listing, medical device reporting, correction, removal, and recall, complaint handling, labeling, investigational device, and quality system requirements. FDA intends to phase in these requirements beginning May 6, 2025. The final rule stated that certain categories of LDTs would be subject to enforcement discretion with respect to some or all of these requirements. For example, FDA would apply enforcement discretion to currently marketed LDTs that were first offered prior to May 6, 2024, with respect to most quality system requirements and the requirement for premarket authorization if they are not modified or modified in only limited ways. Laboratories performing these tests are subject to other requirements, including the requirement to submit the labeling for the LDT to FDA for review. FDA would similarly exercise enforcement discretion with respect to premarket authorization for LDTs approved by the New York State Clinical Laboratory Evaluation Program (“NYS-CLEP”).

On September 19, 2025, the FDA formally rescinded its May 2024 final rule regulating Laboratory Developed Tests (LDTs) as medical devices, following a March 31, 2025, federal court ruling. The U.S. District Court for the Eastern District of Texas found the FDA exceeded its authority, reverting LDT oversight to Clinical Laboratory Improvement Amendments (CLIA). There has been no further pursuit by the current administration.

Results of Operations

The results of operations presented below should be reviewed in conjunction with the consolidated financial statements and notes included elsewhere in this Annual Report on Form 10-K. The following table sets forth Cardio’s results of operations data for the periods presented:

Comparisons for the years ended December 31, 2025 and 2024:

	Years Ended December 31,
	2025			2024
Revenue	$	14,825		$	34,890

Operating Expenses
Sales and marketing		766,888			1,231.969
Research and development		641,212			227,966
General and administrative		5,025,570			6,921,094
Amortization		65,233			19,738
Total operating expenses		(6,498,903	)		(8,400,767	)
Other (expense) income		(14,089	)		(17,576	)
Net (loss)	$	(6,498,167	)	$	(8,383,453	)

Cardio’s net loss for the year ended December 31, 2025 was $6,498,167 as compared to $8,383,453 for the year ended December 31, 2024, a decrease of $1,885,286 primarily as a result of a decrease in General and Administrative expenses associated with stock compensation issued in 2024.

Revenue

Revenue for the year ended December 31, 2025 was $14,825 compared to $34,890 for the year ended December 31, 2024. The decrease in revenue is a result of the conclusion of the Family Medicine Specialists’ Heart Attack Prevention testing initiative.

Additional providers and other organizations are continuing to be onboarded. However, there is a one to three quarter period from onboarding to ramping up usage of tests. The new provider organizations are also smaller and have fewer patients in general than Family Medicine Specialists.

Revenue Growth and Commercial Adoption Considerations

A recurring question from investors is why revenue growth does not immediately follow the development and validation of a clinically promising diagnostic test. While product development may appear straightforward — develop the test, demonstrate its effectiveness, and launch — the path from scientific discovery to broad clinical adoption is complex, highly regulated and typically extended in duration.

The commercialization lifecycle for diagnostic tests generally involves multiple stages:

Scientific Validation

The Company must conduct rigorous analytical and clinical validation studies to demonstrate the safety, accuracy and clinical utility of its tests. Publication of supporting data and peer-reviewed evidence is often an important component of this process.

Regulatory Requirements

Depending on the regulatory pathway, the Company must comply with applicable federal and state regulatory standards. Regulatory processes may involve submissions, inspections, or other oversight requirements that can extend development timelines.

Reimbursement and Coverage

Revenue generation depends significantly on securing third-party reimbursement. Following launch, the Company must obtain coverage determinations from government programs, including the Centers for Medicare & Medicaid Services (“CMS”), and subsequently from commercial payors. Coverage decisions often require demonstration of clinical utility, cost-effectiveness, and economic value relative to the current standard of care. The timing and scope of reimbursement approvals can materially impact adoption rates and revenue growth.

Physician Adoption and Clinical Guidelines

Broad utilization frequently depends on physician awareness, education and confidence in the test. Adoption may accelerate when professional medical societies incorporate a diagnostic test into clinical guidelines; however, guideline inclusion typically follows the accumulation of substantial clinical evidence over time.

Behavioral and Workflow Integration

Even when a test is validated, reimbursed and supported by clinical data, integration into established clinical workflows and physician practice patterns can be gradual. Changes in medical practice often occur incrementally as providers gain familiarity and comfort with new technologies.

In summary, the healthcare commercialization process is inherently lengthy and subject to regulatory, reimbursement, evidentiary, and behavioral factors. Broad clinical adoption of novel diagnostic technologies frequently spans multiple years and, in some cases, may require a decade or more from initial development to widespread utilization.

Sales and Marketing

Expenses related to sales and marketing for the year ended December 31, 2025 were $766,888 as compared to $1,231,969 for the year ended December 31, 2024, a decrease of $465,081. The overall decrease was primarily due to a restructuring in sales and marketing personnel in 2025.

Research and Development

Research and development expense for the year ended December 31, 2025 was $641,212 as compared to $227,966 for the year ended December 31, 2024, an increase of $413,246. The overall increase was due to an increase in research and development personnel in 2025.

General and Administrative Expenses

General and Administrative Expenses for the year ended December 31, 2025 were $5,025,570 as compared to $6,921,094 for the year ended December 31, 2024, a decrease of $1,895,524. The overall decrease is primarily due to a decrease in stock compensation expenses (mainly as a result of new stock options issued in the first quarter of 2024), coupled by the decrease in director and officer insurance expense.

General and Administrative Expenses for the year ended December 31, 2025 included payroll and related costs of $1,366,808, rent and other facility costs of $306,591, legal and professional fees of $868,826, consulting and contractor fees of $715,764, insurance expense of $618,998, filing fees of $99,115, transfer agent fees of $62,228, software and web computing expenses of $316,339, board compensation of $198,235, investor relations expenses of $10,133 and general corporate overhead expenses of $462,533.

General and Administrative Expenses for the year ended December 31, 2024 included payroll and related costs of $3,213,917, rent and other facility costs of $224,123, legal and professional fees of $731,209, consulting and contractor fees of $740,516, insurance expense of $714,481, filing fees of $102,514, transfer agent fees of $67,536, software and web computing expenses of $274,515, board compensation of $199,658, investor relations expense of $82,345 and general corporate overhead expenses of $570,280.

We expect our general corporate overhead to remain relatively flat. Additionally, as a public company, we must comply with changing legal and exchange requirements, including as to regulations of the SEC and the continued listing requirements of the Nasdaq Capital Market. We incur annual expenses related to these matters and, among other things, directors’ and officers’ liability insurance, directors’ fees, reporting requirements of the SEC, transfer agent fees, Nasdaq listing fees, auditing and legal fees and similar expenses.

Amortization

The total amortization expense for the year ended December 31, 2025 was $65,233, consisting of amortization of intangible assets of $5,333 and patent costs of $59,900. The total amortization expense for the year ended December 31, 2024 is $19,738, consisting of intangible assets of $16,000 and patent costs of $3,738.

Other income (expenses)

Total other expense for the year ended December 31, 2025 was $(14,089) as compared to $(17,576) for the year ended December 31, 2024. The total other expense for the year ended December 31, 2025 consists of interest expense of $14,801, net of interest income of $712. The total other expense for the year ended December 31, 2024 consists of interest expense of $18,640, net of interest income of $1,064.

Liquidity and Capital Resources

Liquidity describes the ability of a company to generate sufficient cash flows in the short- and long-term to meet the cash requirements of its business operations, including working capital needs, debt service, acquisitions and investments and other commitments and contractual obligations. We consider liquidity in terms of cash flows from operations and other sources, and their sufficiency to fund our operations. Historically, our principal sources of liquidity have been proceeds from the issuance of equity.

On January 26, 2024, we entered into the Sales Agreement with Craig-Hallum (the “ATM Offering”). Pursuant to the Sales Agreement and ATM Offering, we may sell, at our option, shares of our Common Stock through Craig-Hallum, as sales agent. Sales of our Common Stock were made pursuant to the Sales Agreement initially up to an aggregate of $17 million under a shelf registration statement declared effective in February 2024 (File No. 333-276725) and have been, and may continue to be made pursuant to the Sales Agreement up to an aggregate of an additional $9,476,508 under a second shelf registration statement declared effective in February 2025 (File No. 333-284775).

As of March 13, 2026, we sold an aggregate 2,251,181 shares of our Common Stock on a Reverse Stock Split-adjusted basis under the Sales Agreement resulting in proceeds to the Company of $18,754,735, net of offering costs. The Company has paid Craig-Hallum $480,890 in sales commissions.

On February 2, 2024 (pre-dating the 1-for-30 reverse stock split effected in May 2025), in accordance with executed subscription agreements with seven accredited investors (the “Subscription Agreements”), we closed on the sale of 561,793 units (the “Units”), with each Unit consisting of (i) one share of the Company’s common stock, $0.00001 par value (the “Common Stock”) and (ii) one six year Common Stock purchase warrant (the “Warrants”), which warrants are exercisable until February 2, 2030 at an exercise price of $1.78 ($53.40 on a post-reverse stock split basis) per share, subject to adjustment for stock splits, reverse stock splits and other similar events of recapitalization, including the 1-for-30 reverse stock split we effected on May 12, 2025. The Units were sold to the investors in a private placement at a sale price of $1.78 ($53.40 on a post-reverse stock split basis) per Unit (the “Private Placement”), resulting in gross proceeds to the Company of $1,000,000, before deducting placement agent fees (10% or $100,000) and other offering expenses. We used the net proceeds from the Private Placement for working capital and general corporate purposes. On a post-reverse stock split basis, the Company issued 18,727 shares and warrants that are exercisable for 18,727 shares, all at an exercise price of $53.40 per share. We have subsequently registered the Private Placement Common Stock and the Common Stock issuable upon the exercise of the Private Placement Warrants on a registration statement on Form S-1 that was declared effective by the SEC on December 3, 2024 and subsequently on September 19, 2025.

We have had, and expect that we will continue to have, an ongoing need to raise additional cash from outside sources to fund our operations and grow our business, given the nominal amount of revenue we have generated since inception, coupled with substantial expenses both for ongoing business operations and to fund expenses incurred as a public company. We expect that our primary cash needs for the remainder of 2026 and for the foreseeable future will be for funding day-to-day operations and working capital requirements, funding our growth strategy, paying the setup expenses of our internal laboratory and paying expenses incurred in connection with our ongoing FDA submission activities. We explore our financing options on an ongoing basis. However, given recent stock prices and the extreme volatility of our stock, it continues to be challenging to balance cash that could be raised and the dilution that might be required to close a particular transaction. We expect that for the remainder of 2026, we will rely primarily on the ongoing ATM Offering, provided that market conditions are favorable.

Our long-term future capital requirements will depend on many factors, including revenue growth rate, the timing and the amount of cash received from customers, the expansion of sales and marketing activities, the timing and extent of spending to support investments, including research and development efforts, and the continuing market adoption of our products. In each fiscal year since our inception, we have incurred losses from operations and generated negative cash flows from operating activities. We expect this trend to continue in future periods for the foreseeable future.

Unless we are able to generate significant cash flows from operations, which we do not foresee happening in the near term, we will need to finance our operations through the issuance of additional equity and/or convertible debt securities. Looking forward, we expect we will need to raise additional capital and generate revenues to meet long-term operating requirements. If we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our equity holders could be significantly diluted, particularly at current stock price levels, and these newly-issued securities may have rights, preferences or privileges senior to those of existing equity holders. If we raise additional funds by obtaining loans from third parties, the terms of those financing arrangements may include negative covenants or other restrictions on our business that could impair our operating flexibility and also require us to incur interest expense.

Working capital requirements are expected to increase in line with the growth of the business. We have no lines of credit or other bank financing arrangements. We anticipate that our principal sources of liquidity, including existing funds and the ATM offering will be sufficient to fund our activities over the next 12 months. In order to have sufficient cash to fund our operations beyond the next 12 months and grow our business, we will need to raise additional funds through the issuance of equity and/or debt. We cannot provide any assurance that we will be successful in doing so.

If we are unable to raise additional capital when desired, our business, financial condition and results of operations would be harmed. Successful transition to attaining profitable operations depends upon achieving a level of revenue adequate to support our business plan, balanced against ongoing expenses. There is no assurance that we will be successful in reaching and sustaining profitability.

The exercise prices of our currently outstanding warrants range from a high of $345 to a low of $53.40 (a high of $11.50 to a low of $1.78 before the Reverse Stock Split) (subject to adjustment) per share of Common Stock. The likelihood that warrant holders will exercise their warrants, and therefore the amount of cash proceeds that we might receive, is dependent upon the trading price of our Common Stock, the last reported sales price for which was $4.76 on March 11, 2026. If the trading price of our Common Stock is less than the respective exercise prices of our outstanding warrants, which has been the case for a substantial period of time, we believe holders of any of our warrants will be unlikely to exercise their warrants. There is no guarantee that the warrants will be in the money prior to their respective expiration dates, and as such, the warrants may expire worthless, and we may receive no proceeds from the exercise of warrants. Given the current differential between the trading price of our Common Stock and the Warrant exercise prices and the volatility of our stock price, we are not making strategic business decisions based on an expectation that we will receive any cash from the exercise of warrants. However, we will use any cash proceeds received from the exercise of warrants for general corporate and working capital purposes, which would increase our liquidity. We will continue to evaluate the probability of warrant exercises and the merit of including potential cash proceeds from the exercise of the warrants in our future liquidity projections.

Cash at December 31, 2025 totaled $5,110,630 as compared to $7,827,487 at December 31, 2024, a decrease of $2,716,857. The following table shows our cash flows from operating activities, investing activities and financing activities for the stated periods:

	2025		2024
Net cash used in operating activities	$	5,726,833	$	4,993,104
Net cash used in investing activities		419,310		404,190
Net cash provided by financing activities		3,429,286		11,941,258

Cash provided by financing activities for the year ended December 31, 2024 was due to $12,391,949 in proceeds from the sale of Common Stock and warrants, net of issuance costs, offset by $450,691 in payments pursuant to the Sales Agreement for the ATM Offering.

Off-Balance Sheet Financing Arrangements

We did not have any off-balance sheet arrangements as of December 31, 2025.

Contractual Obligations

As of December 31, 2025, we do not have any ongoing contractual obligations that would have a negative impact on liquidity and cash flows. However, if one or more of the following potential claims that arise from contracts we have entered into were pursued against us, there is the potential that we could see a negative impact on liquidity and cash flows, depending on the outcome.

Prior Relationships of Cardio with Boustead Securities, LLC

At the commencement of efforts to pursue what ultimately ended in the terminated business acquisition, Legacy Cardio entered into a Placement Agent and Advisory Services Agreement (the “Placement Agent Agreement”), dated April 12, 2021, with Boustead Securities, LLC (“Boustead Securities”). This agreement was terminated in April 2022, when Legacy Cardio terminated the underlying agreement and plan of merger and the accompanying escrow agreement relating to that proposed business acquisition after efforts to complete the transaction failed, despite several extensions of the closing deadline.

Under the terminated Placement Agent Agreement, Legacy Cardio agreed to certain future rights in favor of Boustead Securities, including (i) a two-year tail period during which Boustead Securities would be entitled to compensation if Cardio were to close on a transaction (as defined in the Placement Agent Agreement) with any party that was introduced to Legacy Cardio by Boustead Securities; and (ii) a right of first refusal to act as the Company’s exclusive placement agent for 24-months from the end of the term of the Placement Agent Agreement (the “right of first refusal”). Cardio has taken the position that due to Boustead Securities’ failure to perform as contemplated by the Placement Agent Agreement, these provisions purporting to provide future rights are null and void.

Boustead Securities responded to the termination of the Placement Agent Agreement by disputing Legacy Cardio’s contention that it had not performed under the Placement Agent Agreement because, among other things, Boustead Securities had never sought out prospective investors. In its response, Boustead Securities included a list of funds that they had supposedly contacted on Legacy Cardio’s behalf. While Boustead Securities’ contention appears to contradict earlier communications from Boustead Securities in which they indicated that they had not made any such contacts or introductions, Boustead Securities contended that they are due success fees for two years following the termination of the Placement Agent Agreement on any transaction with any person on the list of supposed contacts or introductions. Legacy Cardio strongly disputes this position. Notwithstanding the foregoing, the Company has not consummated any transaction, as defined, with any potential party that purportedly was a contact of Boustead Securities in connection with the Placement Agent Agreement and has no plans to do so at any time during the tail period. No legal proceedings have been instigated by either party.

The Benchmark Company, LLC Right of First Refusal

The Company completed a business combination with Mana on October 25, 2022. In connection with the proposed business combination, by agreement dated May 13, 2022, Mana engaged The Benchmark Company, LLC (“Benchmark”) as its M&A advisor. Upon closing of the business combination, Legacy Cardio assumed the contractual engagement entered into by Mana. On November 14, 2022, Cardio and Benchmark entered into Amendment No. 1 Engagement Letter (the “Amendment Engagement”). Pursuant to the Amendment Engagement, Benchmark has been granted a right of first refusal to act as lead or joint-lead investment banker, lead or joint-lead book-runner and/or lead or joint-lead placement agent for all future public and private equity and debt offerings through October 25, 2023. Based on the right of first refusal, Benchmark alleges that it is owed damages because the Company entered into the Yorkville Convertible Debenture Transaction without first offering Benchmark the right to serve as the lead or joint-lead placement agent for the transaction. No legal proceedings have been instigated.

Demand Letter and Potential Mootness Fee Claim

On June 25, 2022, a plaintiffs’ securities law firm sent a demand letter to the Company alleging that the Company’s Registration Statement on Form S-4 filed (the “S-4 Registration Statement”) with the Securities and Exchange Commission (“SEC”) on May 31, 2022 omitted material information with respect to the Business Combination and demanding that the Company and its Board of Directors immediately provide corrective disclosures in an amendment or supplement to the Registration Statement. Subsequent thereto, the Company filed amendments to the S-4 Registration Statement on July 27, 2022, August 23, 2022, September 15, 2022, October 4, 2022 and October 5, 2022 in which it responded to various comments of the SEC staff and otherwise updated its disclosure. In October 2022, the SEC completed its review and declared the S-4 registration statement effective on October 6, 2022. On February 23, 2023 and February 27, 2023, plaintiffs’ securities law firm contacted the Company’s counsel asking who will be negotiating a mootness fee relating to the purported claims set forth in the June 25, 2022 demand letter. The Company vigorously denies that the S-4 Registration Statement, as amended and declared effective, is deficient in any respect and believes that no additional supplemental disclosures are material or required. The Company believes that the claims asserted in the Demand Letter are without merit and that no further disclosure is required to supplement the S-4 Registration Statement under applicable laws. As of the date of filing of this Annual Report on Form 10-K, no lawsuit has been filed against the Company by that firm.

Northland Securities, Inc.

In January 2024, following the Company’s termination of its agreement with Yorkville and in connection with the Company’s at the market offering and/or its February 2024 private placement, a managing director of Northland Securities, Inc. (“Northland”) contacted the Company claiming the right to be paid a fee of approximately $150,000 pursuant to the agreement of March 1, 2023 between the Company and Northland regarding the Yorkville financing. Subsequently, the Company has been advised by another representative of Northland that Northland would not proceed with any such claim and no legal proceedings have been instigated.

The Company cannot preclude the possibility that claims or lawsuits brought relating to any alleged securities law violations or breaches of fiduciary duty could potentially require significant time and resources to defend and/or settle and distract its management and board of directors from focusing on its business.

Directors and Officers Insurance

In connection with the Company’s various contractual obligations arising in the ordinary course of business, the Company is required to maintain insurance coverage for claims against its directors and officers.

The University of Iowa Research Foundation Exclusive License Agreement

The Company has a worldwide exclusive license agreement with the University of Iowa Research Foundation (UIRF) relating to its patent and patent-pending technology (the “Exclusive License Agreement”). Under the terms of the Exclusive License Agreement, the Company will have to pay each of: (1) 1% of either the: (i) aggregate consideration (and trailing consideration, if any) for a liquidation event; or (ii) pre-money valuation for an initial public offering, (the “Equity Rights”) (2) 2% of annual net sales, and (3) 15% of non-royalty fees paid to licensee if it enters into one or more sublicensing agreements. Upon the Closing of the Business Combination, the Company issued 3,639 (109,170 prior to the Reverse Stock Split) Shares of Common Stock to UIRF in accordance with the Equity Rights under the Exclusive License Agreement. The Company has had minimal sales of $68,631 to date and has paid 2% or approximately $1,300 in total royalty fees to UIRF under the exclusive license.

Nasdaq Continued Listing Compliance

On June 3, 2024, we received notice from The Nasdaq Stock Market LLC (“Nasdaq”) that we were not in compliance with Nasdaq Listing Rule 5550(a)(2) because the closing bid price of our common stock had been below $1.00 per share for 30 consecutive business days. We were provided an initial compliance period and, on December 4, 2024, were granted an additional compliance period through June 2, 2025.

In May 2025, we effected a reverse stock split, after which we regained compliance with the minimum bid price requirement. Nasdaq subsequently notified us that we had regained compliance with Listing Rule 5550(a)(2).

Although we are currently in compliance, the market price of our common stock has historically experienced volatility and may continue to fluctuate due to factors both within and outside of our control, including our operating performance, capital market conditions, investor sentiment toward small-cap healthcare companies, and broader macroeconomic trends. Reverse stock splits do not guarantee sustained increases in market price, and there can be no assurance that we will be able to maintain compliance with the minimum bid price requirement or other Nasdaq continued listing standards in the future.

If the bid price of our common stock were to decline below $1.00 per share for a sustained period, we could again become non-compliant with Nasdaq’s continued listing requirements. In addition, continued listing on Nasdaq requires compliance with other quantitative and qualitative standards, including stockholders’ equity thresholds, market value of publicly held shares, corporate governance requirements, and timely filing obligations.

Any future failure to maintain compliance could result in deficiency notices and, if not cured, could ultimately lead to delisting, which could adversely affect the liquidity and market value of our common stock and our ability to access the capital markets.

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with GAAP in the United States. The preparation of our consolidated financial statements and related disclosures requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, costs and expenses and the disclosure of contingent assets and liabilities in our financial statements. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Management evaluates our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in Note 2 to the consolidated financial statements, we believe that the following accounting policies are those most critical to the judgments and estimates used in the preparation of the consolidated financial statements. Critical accounting policies are those that are most important to the portrayal of our financial condition, results of operations and cash flows and require management’s most difficult, subjective and complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. If actual results were to differ significantly from estimates made, the reported results could be materially affected.

Stock-Based Compensation

We account for stock-based awards granted under our employee compensation plan in accordance with ASC Topic No. 718-20, Awards Classified as Equity, which requires the measurement of compensation expense for all share-based compensation granted to employees and non-employee directors at fair value on the date of grant and recognition of compensation expense over the related service period for awards expected to vest. We use the Black-Scholes option pricing model to estimate the fair value of our stock options and warrants. The Black-Scholes option pricing model requires the input of highly subjective assumptions including the expected stock price volatility of our Common Stock, the risk-free interest rate at the date of grant, the expected vesting term of the grant, expected dividends and an assumption related to forfeitures of such grants. Changes in these subjective input assumptions can materially affect the fair value estimate of our stock options and warrants.

As of December 31, 2025, we were not subject to any market or interest rate risk.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of

Cardio Diagnostics Holdings, Inc.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Cardio Diagnostics Holdings, Inc. (the “Company”) as of December 31, 2025 and 2024, and the related consolidated statements of operations, changes in stockholders’ equity, and cash flows for the years ended December 31, 2025 and 2024, and the related notes (collectively referred to as the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for the years ended December 31, 2025 and 2024, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Notes to Consolidated Financial Statements

Years Ended December 31, 2025 and 2024

Note 1 - Organization and Basis of Presentation

The consolidated financial statements presented are those of Cardio Diagnostics Holdings, Inc., (the “Company”) and its wholly-owned subsidiary, Cardio Diagnostics, Inc. (“Legacy Cardio”). The Company was incorporated as Mana Capital Acquisition Corp. (“Mana”) under the laws of the state of Delaware on May 19, 2021, and Legacy Cardio was formed on January 16, 2017 as an Iowa limited liability company (Cardio Diagnostics, LLC) and was subsequently incorporated as a Delaware C-Corp on September 6, 2019. The Company was formed to develop and commercialize a patent-pending Artificial Intelligence (“AI”)-driven DNA biomarker testing technology (“Core Technology”) for cardiovascular disease invented at the University of Iowa by the Founders, with the goal of becoming one of the leading medical technology companies for enabling precision prevention, early detection and treatment of cardiovascular disease. The Company is transforming the approach to cardiovascular disease from reactive to proactive. The Core Technology is being incorporated into a series of products for major types of cardiovascular disease and associated co-morbidities including coronary heart disease (CHD), stroke, heart failure and diabetes.

Reverse Stock Split

On May 12, 2025, the Company filed a Certificate of Amendment to the Third Amended and Restated Certificate of Incorporation of the Company with the Delaware Secretary of State to effect a reverse stock split at a 1-for-30 ratio (the “Effective Time”). At the Effective Time, every 30 shares of issued and outstanding Common Stock automatically combined into one issued share of common stock, with no change in par value. No fractional shares were issued as a result of the Reverse Stock Split. Instead of issuing fractional shares, the Company rounded shares up or down to the nearest whole number as determined by DTC at the participant level. The Reverse Stock Split did not modify any voting rights or other terms of the Common Stock. The Company’s Common Stock began trading on a reverse stock split-adjusted basis on The Nasdaq Capital Market at the open of the markets on May 13, 2025. As a result, the number of shares of Common Stock outstanding was reduced from 52,160,487 shares to 1,738,683 shares, exclusive of 27 whole shares issued for rounding up fractional shares (which were issued in May 2025), and the number of authorized shares of Common Stock remains 300 million shares.

Unless otherwise indicated, all issued and outstanding stock and per share amounts contained in the accompanying consolidated financial statements have been adjusted to reflect the 1-for-30 Reverse Stock Split for all prior periods presented. Proportionate adjustments were made to the exercise prices and number of shares issuable under the Company’s equity incentive plans, and the number of shares underlying outstanding equity awards, as applicable.

The impacts of the Reverse Stock Split were applied retroactively for all periods presented in accordance with applicable guidance, less the number of rounded whole shares issued for fractional shares on May 12, 2025. Therefore, prior period amounts are different than those previously reported. Certain amounts within the following tables may not foot due to rounding.

The following table illustrates changes in equity, as previously reported prior to, and as adjusted subsequent to, the impact of the Reverse Stock Split retroactively adjusted for the periods presented:

Note 2 – Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, Legacy Cardio. All intercompany accounts and transactions have been eliminated.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Actual results could differ from those estimates.

Segments

The Company uses the “management approach” in determining reportable operating segments. The management approach considers the internal organization and reporting used by the Company’s chief operating decision maker (“CODM”), who is our chief executive officer, for making operating decisions and assessing performance as the source for determining the Company’s reportable segments. Management, including the CODM, reviews operating results solely by monthly revenue and operating results of the Company and, as such, the Company has determined that the Company has one operating segment (product testing) as defined by ASC Topic 280 “Segment Reporting”.

One hundred percent of the Company’s revenues are generated from product tests for major types of cardiovascular disease, and therefore the Company has one operating segment for financial reporting purposes. The Company’s principal products are its Epi+Gen CHD and PrecisionCHD tests. Epi+Gen CHD assesses the risk for a coronary heart disease event, including a heart attack, in the next three years. PrecisionCHD aids in diagnosing and managing coronary heart disease. The tests can be paid for by provider organizations, patients, and/or employers. Customers are generally charged for tests utilized for the minimum committed test volume and the pricing can vary based on organization type, size and volume.

Fair Value Measurements

The Company adopted the provisions of ASC Topic 820, Fair Value Measurements and Disclosures, which defines fair value as used in numerous accounting pronouncements, establishes a framework for measuring fair value and expands disclosure of fair value measurements.

The estimated fair value of certain financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued expenses are carried at historical cost basis, which approximates their fair values because of the short-term nature of these instruments. The carrying amounts of our short- and long-term credit obligations approximate fair value because the effective yields on these obligations, which include contractual interest rates taken together with other features such as concurrent issuances of warrants and/or embedded conversion options, are comparable to rates of returns for instruments of similar credit risk.

ASC 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 describes three levels of inputs that may be used to measure fair value:

Level 1 – quoted prices in active markets for identical assets or liabilities

Level 2 – quoted prices for similar assets and liabilities in active markets or inputs that are observable

Level 3 – inputs that are unobservable (for example cash flow modeling inputs based on assumptions)

Determining which category an asset or liability falls within the hierarchy requires significant judgment. The Company evaluates its hierarchy disclosures each quarter. There are no financial instruments measured at fair value on a recurring basis.

Revenue Recognition

The Company offers its products, Epi+Gen CHD and PrecisionCHD, via telemedicine providers, provider organizations such as concierge practices, and longevity clinics, and employer organizations. The Company is continuing to expand its markets and payment optionality, and therefore, other organization types not listed below may be added, and from time-to-time, there may be additional payment options.

•

Telemedicine

For telemedicine, the telemedicine provider collects payments from patients upon completion of eligibility screening and test order. Patients then send their samples to the lab for biomarker assessments. The Company performs all quality control, analytical assessments and report generation and shares test reports with the ordering healthcare provider. Revenue is recognized upon completing the testing of patient samples. Telemedicine providers are invoiced at the end of each month for all tests completed or orders received since prior invoicing.

•

Provider organizations

For provider organizations, the cost of each test is negotiated prior to testing commencing. Pricing is determined based largely on the provider organization type and testing volume commitment. Upon ordering a test, a patient’s sample is sent to the lab for biomarker assessments. The Company performs all quality control, analytical assessments and report generation and shares test reports with the ordering healthcare provider. Revenue is recognized upon completing the testing of patient samples. The provider organization is invoiced the agreed upon pricing at the end of each month for all samples accepted or tests completed since prior invoicing. Patients are also able to pay directly for the test electronically.

•

Employer organizations

For employer organizations, the cost of each test is negotiated prior to testing commencing. Pricing is determined based largely on testing volume commitment. Patient samples are sent to the lab for biomarker assessments. The Company performs all quality control, analytical assessments and report generation and shares test reports with the ordering healthcare provider. Revenue is recognized upon completing testing of patient samples. The employer organization is invoiced the agreed upon pricing once a heart disease fair is completed or sample is received and accepted or all testing is completed.

The Company accounts for revenue under Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers (Topic 606)”. The Company determines the measurement of revenue and the timing of revenue recognition utilizing the following core principles:

1. Identifying the contract with a customer;

2. Identifying the performance obligations in the contract;

3. Determining the transaction price;

4. Allocating the transaction price to the performance obligations in the contract; and

5. Recognizing revenue when (or as) the Company satisfies its performance obligations.

Research and Development

Research and development costs are expensed as incurred. Research and development costs charged to operations for the years ended December 31, 2025 and 2024 were $641,212 and $227,966, respectively.

Advertising Costs

The Company expenses advertising costs as incurred. Advertising costs of $105,121 and $182,446 were charged to operations for the years ended December 31, 2025 and 2024, respectively.

Cash and Cash Equivalents

Cash and cash equivalents are comprised of cash and highly liquid investments with original maturities of 90 days or less at the date of purchase. The Company does not have any cash equivalents as of December 31, 2025 and 2024. Cash is maintained at a major financial institution. Accounts held at U.S. financial institutions are insured by the FDIC up to $250,000. The Company is exposed to credit risk in the event of default by the financial institutions or the issuers of these investments to the extent the amounts on deposit or invested are in excess of amounts that are insured. The Company’s accounts at this major financial institution may, at times, exceed the federally insured limits. The amount in excess of the FDIC insurance as of December 31, 2025 and 2024, was approximately $4.8 million and $7.5 million, respectively. The Company has not experienced any losses on these accounts and management believes, based upon the quality of this major financial institution, that the credit risk with regard to these deposits is not significant.

Accounts Receivable

Accounts receivable is stated at invoiced amount, net of an allowance for doubtful accounts and bear no interest. An allowance for credit losses is established through a provision for losses charged to expenses. Receivables are charged against the allowance for losses when management believes collectability is unlikely. The allowance (if any) is an amount that management believes will be adequate to absorb estimated losses on existing receivables, based on evaluation of the collectability of the accounts and prior loss experience.

Property and Equipment and Depreciation

Property and equipment are stated at cost. Maintenance and repairs are charged to expense when incurred. When property and equipment are retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the respective accounts and any gain or loss is credited or charged to income. Depreciation is computed using the straight line method over the estimated lives of the respective assets as follows:

Schedule of estimated lives
	Office and computer equipment	5 years
	Furniture and fixtures	7 years
	Lab equipment	7 years
	Leasehold improvements	7 years

Intangible Assets

Intangible assets are acquired individually or as part of a group of assets, and are initially recorded at cost. The cost of a group of assets acquired in a transaction is allocated to the individual assets based on their relative fair values. Intangible assets are carried at cost less accumulated amortization and any recorded impairment. Intangible assets with finite useful lives are amortized using a straight-line method over the period of estimated useful life. The estimated useful life of the Company’s intangible assets (Know-how license) is 5 years. The Company evaluates intangible assets for impairment whenever events or changes in circumstances indicate that the assets might be impaired.

Patent Costs

The Company accounts for patents in accordance with ASC 350-30, General Intangibles Other than Goodwill. The Company capitalizes patent costs representing legal fees associated with filing patent applications and amortize them on a straight-line basis. The Company evaluates its patents’ estimated useful life and begins amortizing the patents when they are brought to the market or otherwise commercialized.

Impairment of Long-Lived Assets

In accordance with ASC 360-10-35, the Company assesses the valuation of components of its long-lived assets whenever events or circumstances dictate that the carrying value might not be recoverable. The Company bases its evaluation on indicators such as the nature of the assets, the future economic benefit of the assets, any historical or future profitability measurements and other external market conditions or factors that may be present. If such factors indicate that the carrying amount of an asset or asset group may not be recoverable, the Company determines whether an impairment has occurred by analyzing an estimate of undiscounted future cash flows at the lowest level for which identifiable cash flows exist. If the estimate of undiscounted cash flows during the estimated useful life of the asset is less than the carrying value of the asset, the Company recognizes a loss for the difference between the carrying value of the asset and its estimated fair value, generally measured by the present value of the estimated cash flows.

Leases

The Company accounts for leases under ASC 842, “Leases”. The Company determines if an arrangement is a lease or contains a lease at inception of the arrangement. Operating lease liabilities are recognized based on the present value of the remaining lease payments, discounted using the discount rate for the lease at the commencement date. As the rate implicit in the lease is not readily determinable for the operating lease, the Company generally uses an incremental borrowing rate based on information available at the commencement date to determine the present value of future lease payments. Operating lease right-of-use assets (“ROU assets”) represent the Company’s right to control the use of an identified asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets are generally recognized based on the amount of the initial measurement of the lease liability. Lease expense is recognized on a straight-line basis over the lease term. The Company elected to keep leases with an initial term of 12 months or less off the balance sheet.

ROU assets are reviewed for impairment when indicators of impairment are present. ROU assets from operating and finance leases are subject to the impairment guidance in ASC 360, Property, Plant, and Equipment, as ROU assets are long-lived nonfinancial assets. ROU assets are tested for impairment individually or as part of an asset group if the cash flows related to the ROU assets are not independent from the cash flows of other assets and liabilities. An asset group is the unit of accounting for long-lived assets to be held and used, which represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities.

Stock-Based Compensation

The Company accounts for its stock-based awards granted under its employee compensation plan in accordance with ASC Topic No. 718-20, Awards Classified as Equity, which requires the measurement of compensation expense for all share-based compensation granted to employees and non-employee directors at fair value on the date of grant and recognition of compensation expense over the related service period for awards expected to vest. The Company uses the Black-Scholes option pricing model to estimate the fair value of its stock options and warrants. The Black-Scholes option pricing model requires the input of highly subjective assumptions including the expected stock price volatility of the Company’s common stock, the risk free interest rate at the date of grant, the expected vesting term of the grant, expected dividends, and an assumption related to forfeitures of such grants. Changes in these subjective input assumptions can materially affect the fair value estimate of the Company’s stock options and warrants.

Income Taxes

The Company accounts for income taxes using the asset and liability method in accordance with ASC Topic No. 740, Income Taxes. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse.

The Company applies the provisions of ASC Topic No. 740 for the financial statement recognition, measurement and disclosure of uncertain tax positions recognized in the Company’s financial statements. In accordance with this provision, tax positions must meet a more-likely-than-not recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position.

Reclassification

Certain prior period amounts have been reclassified to conform with the current period presentation. On the consolidated statements of changes in stockholders’ equity and cash flows, payment of placement agent fee has been combined with common stock and warrants issued for cash rather than being separated out, to present net proceeds. On the consolidated statements of operations, prior period amounts of sales and marketing, research and development, and general and administrative under operating expenses have been reclassified to conform with 2025 fiscal year presentation for better reflecting the function of these expenses.

Recent Accounting Pronouncements

Recently adopted accounting pronouncements

Income Taxes

In December 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 is intended to improve income tax disclosures primarily through enhanced disclosure of income tax rate reconciliation items, and disaggregation of income (loss) from continuing operations, income tax expense (benefit) and income taxes paid, net disclosures by federal, state and foreign jurisdictions, among others. ASU 2023-09 was effective for annual reporting periods beginning after December 15, 2024. We adopted this ASU on a prospective basis effective January 1, 2025. Refer to Note 10, Income Taxes for the inclusion of new disclosures required.

Recently issued accounting pronouncements not yet adopted

Disaggregation of Income Statement Expenses

In November 2024, the FASB issued ASU No. 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses”, which requires disaggregated disclosure of income statement expenses for public business entities. ASU 2024-03 requires new financial statement disclosures in tabular format, disaggregating information about prescribed categories underlying any relevant income statement expense caption. The prescribed categories include, among other things, purchases of inventory, employee compensation, depreciation, and intangible asset amortization. Additionally, entities must disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and for interim reporting periods within fiscal years beginning after December 15, 2027. The guidance can be applied prospectively with an option for retrospective application. Early adoption is also permitted. We are currently evaluating the provisions of this ASU.

Financial Instruments – Measurement of Credit Losses for Accounts Receivable and Contract Assets

In July 2025, the FASB issued ASU No. 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. The amendments in this update provide a practical expedient permitting an entity to assume that conditions at the balance sheet date remain unchanged over the life of the asset when estimating expected credit losses for current classified accounts receivable and contract assets. This update is effective for annual periods beginning after December 15, 2025, including interim periods within those fiscal years. Adoption of this ASU can be applied prospectively for reporting periods after its effective date. Early adoption is permitted. The Company is currently evaluating the impact that ASU 2025-05 will have on the consolidated financial statements.

We have reviewed other recent accounting pronouncements and concluded they are either not applicable to the business, or no material effect is expected on the consolidated financial statements as a result of future adoption.

Finance leases are included in property and equipment, current portion of finance lease obligations and finance lease obligations, net of current portion in the Company’s consolidated balance sheets.

ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. In addition, ROU assets include initial direct costs incurred by the lessee as well as any lease payments made at or before the commencement date and exclude lease incentives. The Company used the implicit rate in the lease in determining the present value of lease payments. Lease terms include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Leases with a term of one year or less are generally not included in ROU assets and corresponding operating lease liabilities.

Common Stock Issued

Private Placement

On February 2, 2024 (pre-dating the 1-for-30 reverse stock split effected in May 2025), in accordance with executed subscription agreements with seven accredited investors (the “Subscription Agreements”), the Company closed on the sale of 561,793 units (the “Units”), with each Unit consisting of (i) one share of the Company’s common stock, $0.00001 par value (the “Common Stock”) and (ii) one six year Common Stock purchase warrant (the “Warrants”), which warrants are exercisable until February 2, 2030 at an exercise price of $1.78 ($53.40 on a post-reverse stock split basis) per share, subject to adjustment for stock splits, reverse stock splits and other similar events of recapitalization, including the 1-for-30 reverse stock split the Company effected on May 12, 2025. The Units were sold to the investors in a private placement at a sale price of $1.78 ($53.40 on a post-reverse stock split basis) per Unit (the “Private Placement”), resulting in gross proceeds to the Company of $1,000,000, before deducting placement agent fees (10% or $100,000) and other offering expenses. The Company used the net proceeds from the Private Placement for working capital and general corporate purposes.

Notes to Consolidated Financial Statements

Years Ended December 31, 2025 and 2024

As of December 31, 2025, the Company had federal net operating loss carryforwards of approximately $23.5 million which may be carried forward indefinitely, and state net operating loss carryforwards of approximately $624,000 (Iowa) and $22.8 million (Illinois), respectively which expire at various dates from 2040 through 2045. These net operating loss carryforwards may be used to offset future taxable income and thereby reduce the Company’s U.S. federal income taxes. The net operating losses may be subject to limitation under Internal Revenue Code Section 382 should there be a greater than 50% change in ownership as determined under the regulations.

In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. Based on the assessment, management has established a full valuation allowance against all of the deferred tax assets for every period because it is more likely than not that all of the deferred tax assets will not be realized.

In accordance with ASC 740, a valuation allowance must be established if it is more likely than not that the deferred tax assets will not be realized. This assessment is based upon consideration of available positive and negative evidence, which includes, among other things, the Company’s most recent results of operations and expected future profitability. Based on the Company’s cumulative losses in recent years, a full valuation allowance against the Company’s deferred tax assets as of December 31, 2025 and 2024 respectively has been established as Management believes that the Company will not more likely than not realize the benefit of those deferred tax assets. Therefore, no tax provision has been recorded for the years ended December 31, 2025 and 2024, respectively.

The Company complies with the provisions of ASC 740-10 in accounting for its uncertain tax positions. ASC 740-10 addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under ASC 740-10, the Company may recognize the tax benefit from an uncertain tax position only if it is more likely that not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. Management has determined that the Company has no significant uncertain tax positions requiring recognition under ASC 740-10.

The Company is subject to income tax in the U.S., and certain state jurisdictions. The Company has not been audited by the U.S. Internal Revenue Service, or any states in connection with income taxes. The federal and state tax authorities can generally reduce a net operating loss (but not create taxable income) for a period outside the statute of limitations in order to determine the correct amount of net operating loss which may be allowed as a deduction against income for a period within the statute of limitations.

The Company recognizes interest and penalties related to unrecognized tax benefits, if incurred, as a component of income tax expense. No interest or penalties have been recorded for the years ended December 31, 2025 and 2024, respectively.

Note 11 – Commitments and Contingencies

Prior Relationship of Cardio with Boustead Securities, LLC

At the commencement of efforts to pursue what ultimately ended in a terminated business acquisition, Legacy Cardio entered into a Placement Agent and Advisory Services Agreement (the “Placement Agent Agreement”), dated April 12, 2021, with Boustead Securities, LLC ("Boustead Securities”). This agreement was terminated in April 2022, when Legacy Cardio terminated the underlying agreement and plan of merger and the accompanying escrow agreement relating to that proposed business acquisition after efforts to complete the transaction failed, despite several extensions of the closing deadline.

Years Ended December 31, 2025 and 2024

Boustead Securities responded to the termination of the Placement Agent Agreement by disputing Legacy Cardio’s contention that it had not performed under the Placement Agent Agreement because, among other things, Boustead Securities had never sought out prospective investors. In its response, Boustead Securities included a list of funds that they had supposedly contacted on Legacy Cardio’s behalf. While Boustead Securities’ contention appears to contradict earlier communications from Boustead Securities in which they indicated that they had not made any such contacts or introductions, Boustead Securities contended that they were due success fees for two years following the termination of the Placement Agent Agreement on any transaction with any person on the list of supposed contacts or introductions. Legacy Cardio strongly disputed this position. Notwithstanding the foregoing, the Company has not consummated any transaction, as defined, with any potential party that purportedly was a contact of Boustead Securities in connection with the Placement Agent Agreement and had no plans to do so at any time during the tail period. No legal proceedings have been instigated by either party.

The Benchmark Company, LLC Right of First Refusal

The Company completed the business combination on October 25, 2022. In connection with the proposed business combination, by agreement dated May 13, 2022, Mana engaged The Benchmark Company, LLC (“Benchmark”) as its M&A advisor. Upon closing of the business combination, Legacy Cardio assumed the contractual engagement entered into by Mana. On November 14, 2022, the Company and Benchmark entered into Amendment No. 1 Engagement Letter (the “Amendment Engagement”). Pursuant to the Amendment Engagement, the parties agreed that the Company would pay Benchmark $230,000 at the closing of the business combination and an additional $435,000 on October 25, 2023. Both of those payments have been made in full. In addition, the Amendment Engagement provided that Benchmark has been granted a right of first refusal to act as lead or joint-lead investment banker, lead or joint-lead book- runner and/or lead or joint-lead placement agent for all future public and private equity and debt offerings through October 25, 2023. Based on the right of first refusal, Benchmark alleges that it is owed damages because the Company entered into the Yorkville Convertible Debenture Transaction without first offering Benchmark the right to serve as the lead or joint-lead placement agent for the transaction. No legal proceedings have been instigated.

Demand Letter and Potential Mootness Fee Claim

On June 25, 2022, a plaintiffs’ securities law firm sent a demand letter to the Company alleging that the Company’s Registration Statement on Form S-4 filed (the “S-4 Registration Statement”) with the Securities and Exchange Commission (“SEC”) on May 31, 2022 omitted material information with respect to the Business Combination and demanding that the Company and its Board of Directors immediately provide corrective disclosures in an amendment or supplement to the Registration Statement. Subsequent thereto, the Company filed amendments to the S-4 Registration Statement on July 27, 2022, August 23, 2022, September 15, 2022, October 4, 2022 and October 5, 2022 in which it responded to various comments of the SEC staff and otherwise updated its disclosure. In October 2022, the SEC completed its review and declared the S-4 registration statement on effective October 6, 2022. On February 23, 2023 and February 27, 2023, plaintiffs’ securities law firm contacted the Company’s counsel asking who will be negotiating a mootness fee relating to the purported claims set forth in the June 25, 2022 demand letter. The Company vigorously denies that the S-4 Registration Statement, as amended and declared effective, is deficient in any respect and that no additional supplemental disclosures are material or required. The Company believes that the claims asserted in the Demand Letter are without merit and that no further disclosure is required to supplement the S-4 Registration Statement under applicable laws. As of the date of filing of this Annual Report on Form 10-K, no lawsuit has been filed against the Company by that firm.

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our principal executive officer and principal financial and accounting officer, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2025, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on this evaluation, our principal executive officer and principal financial and accounting officer have concluded that during the period covered by this report, our disclosure controls and procedures were not effective. As a result, we performed additional analysis as deemed necessary to ensure that our financial statements were prepared in accordance with U.S. generally accepted accounting principles. Accordingly, management believes that the financial statements included in this Form 10-K present fairly in all material respects our financial position, results of operations and cash flows for the period presented.

Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

We do not expect that our disclosure controls and procedures will prevent all errors and all instances of fraud. Disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Further, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and the benefits must be considered relative to their costs. Because of the inherent limitations in all disclosure controls and procedures, no evaluation of disclosure controls and procedures can provide absolute assurance that we have detected all our control deficiencies and instances of fraud, if any. The design of disclosure controls and procedures also is based partly on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Management’s Report on Internal Controls Over Financial Reporting

Management identified the following material weakness in our internal control over financial reporting: inadequate segregation of duties within the financial reporting process due to our limited staff resources, which increases the risk of errors or unauthorized transactions. This weakness was identified in our assessment during the fiscal year ended December 31, 2025.

Inadequate Segregation of Duties. This material weakness did not result in a material misstatement of the Company’s consolidated financial statements for the periods presented.

Remediation Plans. To address the material weakness related to inadequate segregation of duties, we explored the following remediation measures during the year ended December 31, 2025:

•

Implementation of Approval Matrices: We are developing a formalized approval matrix requiring dual authorization for significant transactions, such as payments above a specified threshold or changes to the general ledger, to enhance oversight despite staffing constraints.

•

Automation of Key Processes: We are exploring and deploying accounting software with built-in controls to automate certain financial processes, reducing reliance on manual interventions and minimizing error risks.

These remediation efforts are in progress and have not yet been fully implemented or tested for effectiveness as of December 31, 2025.

While we believe that these efforts will continue to improve our internal control over financial reporting, our remediation efforts are ongoing and will require validation. The actions that we are taking are subject to ongoing senior management review. We will not be able to conclude whether the steps we are taking will fully remediate the remaining material weakness in our internal control over financial reporting until we have completed our remediation efforts and subsequent evaluation of their effectiveness. We may also conclude that additional measures may be required to remediate the material weakness in our internal control over financial reporting.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting during the period ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 9B. Other Information

During the Company’s fourth quarter, no director or officer adopted or terminated a Rule 10b5-1 trading arrangement or a non-Rule 10b5-1 trading arrangement.

Biographical Information

Executive Officers

The following is a brief biography of each of our executive officers:

Meeshanthini V. Dogan has served as our Chief Executive Officer and a director since inception. Together with Dr. Philibert, she is the Co-Founder of Legacy Cardio, with over 15 years’ experience in bridging medicine, engineering and artificial intelligence towards building solutions to fulfill unmet clinical needs such as in cardiovascular disease prevention and management. Coming from a family with a two-generation history of heart disease and having worked for an extensive time interacting with those affected by heart disease, she understands the pain points and founded Legacy Cardio to help prevent others from experiencing its devastating impacts. Dr. Dogan is a pioneer in artificial intelligence/machine learning-driven integrated genetic-epigenetic approaches, which includes highly cited publications, and platform presentations at the American Heart Association and American Society of Human Genetics. She co-invented the proprietary AI-driven Multi-Omics Engine™ of Cardio Diagnostics (six granted patents and numerous pending patents). In 2017, Dr. Dogan founded Legacy Cardio to commercialize this technology through a series of patent-pending clinical tests towards making heart disease prevention and early detection more accessible, personalized and precise. Under her leadership, Legacy Cardio was awarded the prestigious One To Watch award in 2020 by Nature and Merck, the 2021 Clinical Diagnostics Solution of the Year from Biotech Breakthrough and Fast Company's Next Big Things in Tech 2022, has worked its way to become a technology leader in cardiovascular diagnostics, launched products, secured both dilutive and non-dilutive funding and key relationships with world renowned healthcare organizations and key opinion leaders. Dr. Dogan holds a PhD degree in Biomedical Engineering and BSE/MS degrees in Chemical Engineering from University of Iowa. She was named FLIK Woman Entrepreneur to Watch in 2021. We believe that, as a co-founder of our Company and co-inventor of our Company’s key technologies and products, as well as her leadership skills, Dr. Dogan is uniquely positioned to bring unmatched experience and insights into the boardroom and to the daily operations of our Company.

Robert Philibert has served as our Chief Medical Officer and as a director since inception. Together with Dr. Dogan, he is a co-founder of Legacy Cardio. Dr. Philibert graduated from the University of Iowa Medical Scientist Training Program and completed a residency in Psychiatry at the University of Iowa. Between 1993 and 1998, he completed a Pharmacology Research Training Program (“PRAT”) Fellowship and a Staff Fellowship at the National Institutes of Health while also serving in the United States Uniformed Public Health Service. In late 1998, he returned to the University of Iowa where he now is a Professor of Psychiatry, with joint appointments in Neuroscience, Molecular Medicine and Biomedical Engineering. He has published over 170 peer reviewed manuscripts and is the recipient of numerous NIH grant awards and both national and international patents for his pioneering work in epigenetics. In particular, he is credited with discovering the epigenetic signatures for cigarette and alcohol consumption.

Family Relationships

Other than Meeshanthini Dogan and Timur Dogan, who are wife and husband, there are no family relationships among our executive officers and directors.

Corporate Governance

Cardio has structured its corporate governance in a manner that we believe closely aligns its interests with those of its stockholders. Notable features of this corporate governance include:

Cardio has independent director representation on its audit, compensation and nominating and corporate governance committees, and its independent directors will meet regularly in executive sessions without the presence of its corporate officers or non-independent directors;

at least one of its directors has qualified as an “audit committee financial expert” as defined by the SEC; and

it has and will implement a range of other corporate governance best practices, including a robust director education program.

Leadership Structure of the Board

The roles of our Non-Executive Chairman and our Chief Executive Officer have been separated. We believe that this is appropriate under current circumstances because it allows management to make the operating decisions necessary to manage the business, while separating out oversight function of the Board and operating decisions. We feel that this has provided an appropriate balance of operational focus, flexibility and oversight. We do not separately have a lead independent director. Currently, Dr. Hosseinion serves as Non-executive Chairman of the Board, participates in setting the agenda of Board and committee meetings, facilitating communications among members of the Board and management, and maintaining the focus and punctuality of Board and committee meetings. Dr Hosseinion also currently leads the efforts in evaluating our Chief Executive Officer and in succession planning, considering Board committee membership and leadership. He will be presiding at this Annual Meeting.

Background and Experience of Directors

Our nominating and corporate governance committee is responsible for, among other things, identifying individuals qualified to become members of our board of directors, consistent with criteria approved by our board of directors, overseeing succession planning for our Chief Executive Officer and other executive officers, periodically reviewing our board of directors’ leadership structure and recommending any proposed changes to our board of directors, overseeing an annual evaluation of the effectiveness of our board of directors and its committees, and developing and recommending to our Board of Directors a set of corporate governance guidelines.

Composition of the Board of Directors and Company Officers

Cardio’s business and affairs are managed under the direction of our board of directors.

Our board consists of seven directors. The board of directors are elected each year at the annual meeting of stockholders.

Our officers are appointed by the board of directors and serve at the discretion of the board of directors, rather than for specific terms of office, subject to the terms of employment agreements, where applicable. The board of directors is authorized to appoint persons to the offices set forth in our bylaws as it deems appropriate. The Company’s bylaws provide that our officers may consist of a Chairman of the Board, Chief Executive Officer, Chief Financial Officer, President, one or more Vice Presidents, Secretary, Treasurer, one or more Assistant Secretaries and such other offices as may be determined by the board of directors.

Director Independence

The Nasdaq listing standards require that a majority of our Board of Directors be independent. An “independent director” is defined generally as a person who has no material relationship with the listed company (either directly or as a partner, stockholder or officer of an organization that has a relationship with the company). Our independent directors hold regularly scheduled meetings at which only independent directors are present. Any affiliated transactions must be on terms no less favorable to the Company than could be obtained from independent parties. Our Board of Directors reviews and approves all affiliated transactions with any interested director abstaining from such review and approval.

Based on information provided by each director concerning his or her background, employment and affiliations, the Board has determined that Paul Burton, James Intrater, Wendy Betts, and Peter Fung, MD, representing four of the Company’s seven directors, do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is an “independent director” as defined under the listing standards of Nasdaq and applicable SEC rules. In making these determinations, the Board considered the current and prior relationships that each non-employee director has with the Company and all other facts and circumstances that the Board deemed relevant in determining their independence, including the beneficial ownership of the Company capital stock by each non- employee director, and the transactions involving them. See “Certain Cardio Relationships and Related Persons Transactions.”

Board Committees

The standing committees of the Cardio Board consist of an audit committee, a compensation committee and a nominating and corporate governance committee. The board of directors may from time to time establish other committees.

Cardio’s chief executive officer and other executive officers regularly report to the non-executive directors and the audit, the compensation and the nominating and corporate governance committees to ensure effective and efficient oversight of our activities and to assist in proper risk management and the ongoing evaluation of management controls.

Audit Committee

Cardio has an audit committee consisting of Paul Burton, James Intrater and Wendy Betts, with Mr. Burton serving as the chair of the committee. The Cardio Board has determined that each member of the audit committee qualifies as an independent director under the independence requirements of the Sarbanes-Oxley Act, Rule 10A-3 under the Exchange Act and Nasdaq listing requirements. The Cardio Board has determined that Mr. Burton qualifies as an “audit committee financial expert,” as defined in Item 407(d)(5) of Regulation S-K, and that he possesses financial sophistication, as defined under the rules of Nasdaq. Mr. Burton was selected to serve on our Board and as the chair of our audit committee due to his extensive experience working in numerous capacities with early-stage healthcare companies as well as his corporate finance background, both of which are areas of expertise that bring invaluable insights to the Cardio boardroom.

The audit committee’s responsibilities include, among other things:

reviewing and discussing with management and the independent auditor the annual audited financial statements, and recommending to the Board whether the audited financial statements should be included in our Form 10-K;

discussing with management and the independent auditor significant financial reporting issues and judgments made in connection with the preparation of our financial statements;

establishing procedures for the receipt, retention and treatment of complaints received by us regarding accounting, internal accounting controls or reports which raise material issues regarding our financial statements or accounting policies; and

approving reimbursement of expenses incurred by our management team in identifying potential target businesses.

The board of directors has adopted a written charter for the audit committee that is available on our website.

Compensation Committee

Cardio has a compensation committee consisting of James Intrater, Paul Burton and Peter Fung, MD with Mr. Intrater serving as chair of the committee. The Cardio Board has determined that each member of the compensation committee qualifies as an independent director under the independence requirements of the Sarbanes-Oxley Act, Rule 10A-3 under the Exchange Act and Nasdaq listing requirements.

The compensation committee’s responsibilities include, among other things:

establishing, reviewing, and approving our overall executive compensation philosophy and policies;

reviewing and approving on an annual basis the corporate goals and objectives relevant to our Chief Executive Officer’s compensation, evaluating our Chief Executive Officer’s performance in light of such goals and objectives and determining and approving the remuneration (if any) of our Chief Executive Officer based on such evaluation;

reviewing and approving the compensation of all of our other executive officers;

approving reimbursement of expenses incurred by our management team in identifying potential target businesses.

reviewing our executive compensation policies and plans;

if required, producing a report on executive compensation to be included in our annual proxy statement;

reviewing and recommending to the Board for approval the frequency with which we will conduct Say-on-Pay Votes, taking into account the results of the most recent stockholder advisory vote on frequency of Say-on-Pay Votes required by Section 14A of the Exchange Act, and review and recommend to the Board for approval the proposals regarding the Say- on-Pay Vote and the frequency of the Say-on-Pay Vote to be included in our proxy statements filed with the SEC;

conducting an annual performance evaluation of the committee; and

reviewing, evaluating and recommending changes, if appropriate, to the remuneration for directors.

The board of directors has adopted a written charter for the compensation committee that is available on our website.

Compensation Committee Interlocks and Insider Participation

None of our executive officers serves as a member of the compensation committee of the board of directors (or other committee performing equivalent functions) of any entity that has one or more executive officers serving on our board of directors.

Nominating and Corporate Governance Committee

Cardio has a nominating and corporate governance committee consisting of Wendy Burton, James Intrater, and Peter Fung, MD with Ms. Betts serving as chair of the committee. The Cardio Board has determined that each member of the nominating and corporate governance committee qualifies as an independent director under the independence requirements of the Sarbanes-Oxley Act, Rule 10A-3 under the Exchange Act and Nasdaq listing requirements.

The nominating and corporate governance committee’s responsibilities include, among other things, to:

review and assess and make recommendations to the board of directors regarding desired qualifications, expertise and characteristics sought of board members;

administer policies and procedures for communications with the non-management members of the Company’s Board of Directors.

The board of directors has adopted a written charter for the nominating and corporate governance committee that is available on our website.

Guidelines for Selecting Director Nominees

The guidelines for selecting nominees generally provide that persons to be nominated:

should have demonstrated notable or significant achievements in business, education or public service;

should possess the requisite intelligence, education and experience to make a significant contribution to the Board of Directors and bring a range of skills, diverse perspectives and backgrounds to its deliberations; and

should have the highest ethical standards, a strong sense of professionalism and intense dedication to serving the interests of the stockholders.

The nominating and governance committee will consider a number of qualifications relating to management and leadership experience, background and integrity and professionalism in evaluating a person’s candidacy for membership on the Board of Directors. The nominating and governance committee may require certain skills or attributes, such as financial or accounting experience, to meet specific board needs that arise from time to time and will also consider the overall experience and makeup of its members to obtain a broad and diverse mix of board members. The nominating and governance committee does not distinguish among nominees recommended by stockholders and other persons.

Code of Ethics

The Company has adopted a written code of business conduct and ethics that applies to its principal executive officer, principal financial or accounting officer or person serving similar functions and all of our other employees and members of our board of directors. The code of ethics codifies the business and ethical principles that govern all aspects of our business. Cardio intends to make any legally required disclosures regarding amendments to, or waivers of, provisions of our code of ethics on our website.

Compensation Recovery (“Clawback”) Policy

Effective October 2, 2023, we adopted a compensation recovery policy (the “Clawback Policy”), which provides that if we are required to prepare an accounting restatement due to any material non-compliance with financial reporting requirements under the federal securities laws, then the Board or a duly established committee thereof may require certain officers, including our executive officers named in the Summary Compensation Table presented later in this proxy statement (our “NEOs”), to repay or forfeit any “excess compensation” in the event it finds, in its sole discretion, that the executive officer contributed to the circumstances requiring the restatement and that it involved either (a) intentional misconduct or an intentional violation of any of the Company’s rules or applicable legal or regulatory requirements or (b) fraud. “Excess compensation” refers to the pre-tax amount in excess of what would have been paid to the executive officer under the accounting restatement of any incentive-based compensation that is granted, earned or vested based on the attainment of a performance measure during the three-year period preceding the date on which we are required to prepare such accounting restatement. The Clawback Policy applies to incentive-based compensation granted after the adoption of this policy.

Conflicts of Interest

Potential investors should be aware of the following potential conflicts of interests:

None of our officers and directors is required to commit their full time to our affairs and, accordingly, they may have conflicts of interest in allocating their time among various business activities.

In the course of their other business activities, our officers and directors may become aware of investment and business opportunities which may be appropriate for presentation to our company as well as the other entities with which they are affiliated. Our Management has pre-existing fiduciary duties and contractual obligations to such entities (as well as to us) and may have conflicts of interest in determining to which entity a particular business opportunity should be presented.

Our officers and directors may in the future become affiliated with entities engaged in business activities similar to those intended to be conducted by our company.

The conflicts described above may not be resolved in our favor.

All ongoing and future transactions between us and any of our management team or their respective affiliates, will be on terms believed by us to be no less favorable to us than are available from unaffiliated third parties. Such transactions will require prior approval by a majority of our uninterested "independent” directors or the members of our board of directors who do not have an interest in the transaction, in either case who had access, at our expense, to our attorneys or independent legal counsel. We will not enter into any such transaction unless our disinterested "independent” directors determine that the terms of such transaction are no less favorable to us than those that would be available to us with respect to such a transaction from unaffiliated third parties.

Limitation on Liability and Indemnification of Officers and Directors

The Company intends to enter into indemnification agreements with each of its directors and executive officers that may be broader than the specific indemnification provisions contained in the DGCL. These indemnification agreements, which have been authorized for execution by the Cardio board of directors, requires the Company, among other things, to indemnify its directors and executive officers against liabilities that may arise by reason of their status or service. These indemnification agreements also require the Company to advance all expenses reasonably and actually incurred by its directors and executive officers in investigating or defending any such action, suit or proceeding. Our By-laws provide that Cardio must indemnify and advance expenses to Cardio’s directors and officers to the fullest extent authorized by the DGCL. We believe that these agreements and By-laws provisions are necessary to attract and retain qualified individuals to serve as directors and executive officers.

Cardio maintains insurance policies under which its directors and officers are insured, within the limits and subject to the limitations of those policies, against certain expenses in connection with the defense of, and certain liabilities which might be imposed as a result of, actions, suits, or proceedings to which they are parties by reason of being or having been its directors or officers. The coverage provided by these policies may apply whether or not the Company would have the power to indemnify such person against such liability under the provisions of the DGCL. At present, we are not aware of any pending litigation or proceeding involving any person who will be one of the Company’s directors or officers or is or was one of its directors or officers, or is or was one of its directors or officers serving at its request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, for which indemnification is sought, and we are not aware of any threatened litigation that may result in claims for indemnification.

The DGCL authorizes corporations to limit or eliminate the personal liability of directors of corporations and their stockholders for monetary damages for breaches of directors’ fiduciary duties, subject to certain exceptions. Our Second Amended and Restated Certificate of Incorporation includes a provision that eliminates the personal liability of directors for damages for any breach of fiduciary duty as a director where, in civil proceedings, the person acted in good faith and in a manner that person reasonably believed to be in or not opposed to the best interests of our Company or, in criminal proceedings, where the person had no reasonable cause to believe that his or her conduct was unlawful.

The limitation of liability, advancement and indemnification provisions in our Second Amended and Restated Certificate of Incorporation and our By-laws may discourage stockholders from bringing lawsuit against directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit Cardio and our stockholders. In addition, investors may be adversely affected to the extent Cardio pays the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

There is currently no pending material litigation or proceeding involving any of Cardio’s directors, officers, or employees for which indemnification is sought.

Section 16(a) Beneficial Ownership Reporting Compliance; Delinquent Section 16(a) Reports

Section 16(a) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, requires our executive officers, directors, and persons who beneficially own more than 10% of a registered class of our equity securities to file with the Securities and Exchange Commission initial reports of ownership and reports of changes in ownership of our shares of common stock and other equity securities. These executive officers, directors, and greater than 10% beneficial owners are required by SEC regulation to furnish us with copies of all Section 16(a) forms filed by such reporting persons.

Based solely on our review of such forms furnished to us and written representations from certain reporting persons, we believe that, during the fiscal year ended December 31, 2025, our directors, executive officers, and ten percent stockholders complied with all Section 16(a) filing requirements, except with respect to: (i) an option grant of 151 shares on a post-Reverse Stock Split basis made on December 31, 2024 to Mr. Intrater, a Form 4 for which was filed on January 15, 2025, (ii) an option grant of 151 shares on a post-Reverse Stock Split basis made on December 31, 2024 to Mr. Burton a Form 4 for which was filed on January 15, 2025, (iii) an option grant of 76 shares on a post-Reverse Stock Split basis made on December 31, 2024 to Ms. Betts a Form 3 for which was filed on February 5, 2025, (iv) an option grant of 76 shares on a post-Reverse Stock Split basis made on December 31, 2024 to Dr. Fung a Form 3 for which was filed on March 13, 2025, (v) option grants of 1,559 shares each made on September 30, 2025 to each of Dr. Fung, Ms. Betts, Mr. Intrater, and Mr. Burton for which Forms 4 were filed on October 3, 2025. As a result, each of Dr. Fung, Ms. Betts, Mr. Intrater, and Mr. Burton each had 2 delinquent filings in 2025.

Securities Trading

The Company has adopted a Securities Trading Policy that governs the purchase, sale, and/or other dispositions of the Company's securities by our directors, officers and employees that are reasonably designed to promote compliance with insider trading laws, rules and regulations, and any listing standards applicable to the Company. A copy of our policy against insider trading is incorporated by reference as Exhibit 19.1 to this Annual Report. Our policy against insider trading prohibits directors, officers, employees and other covered persons from engaging in transactions while aware of material nonpublic information about the Company. Directors, officers and certain other employees are subject to pre-clearance requirements for all transactions in the Company’s securities and are generally prohibited from transacting in the Company’s securities during designated blackout periods. Our policy against insider trading prohibits employees, officers and directors from engaging in any speculative or hedging transactions in our securities. We prohibit transactions such as puts, calls, swaps, forward sale contracts, and other derivatives or similar arrangements or instruments designed to hedge or offset decreases in the market value of our securities. No employee, officer or director may engage in short sales of our securities, hold our securities in a margin account, purchase shares of our stock on margin or pledge our securities as collateral for a loan.

Item 11. Executive Compensation

Overview

This section discusses the material components of the executive compensation program for our executive officers who are named in the “2025 Summary Compensation Table” below. For the year ended December 31, 2025, our “named executive officers” (“NEOs”) and their positions were as follows:

Meeshanthini V. Dogan, Chief Executive Officer;

Warren Hosseinion, Non-executive Chairman of the Board*; and

Elisa Luqman, Chief Financial Officer

Timur Dogan, Chief Technology Officer

*Dr. Hosseinion provides ongoing services to our company as Chairman of the Board and as a consultant. As such, he is not an executive officer and would not be included in the executive compensation tables or accompanying narrative as an NEO under SEC disclosure rules. However, because his contractual compensation is significant and would be payable to him, even if he were no longer our Chairman, we are treating him as an NEO in this Item 11 in the interest of full disclosure of the compensation payable to the highest paid persons who work for our company. Dr. Hosseinion is not considered a Named Executive Officer for any purpose other than the following disclosures.

Narrative to the Summary Compensation Table

2025 Base Salary

The named executive officers receive a base salary to compensate them for services rendered to our company. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities. In 2025, the base salaries paid to each of Dr. Dogan, Dr. Hosseinion, Ms. Luqman and Mr. Dogan are set forth in the “Summary Compensation Table” above in the column titled “Salary.” Each of the NEOs has entered into an employment agreement (or, in the case of Dr. Hosseinion, a Non- Executive Chairman and Consulting Agreement), which became effective as of the Closing of the Business Combination. A brief summary of those agreements is set forth below under the caption, “Agreements with Our Executive Officers and Non-Executive Chairman of the Board.”

Annual Bonuses

We do not currently maintain an annual bonus program for our employees, including our named executive officers. However, the employment agreements and, in the case of Dr. Hosseinion, his Non-Executive Chairman and Consulting Agreement, provide that our named executive officers are eligible to receive an annual cash bonus based on the extent to which, in the discretion of the Board, each such person achieves or exceeds specific and measurable individual and Company performance objectives. The Board did not award any annual bonuses in 2025 and 2024.

Equity Compensation

The Cardio Diagnostics Holdings, Inc. 2022 Equity Incentive Plan (the “2022 Equity Plan”), was adopted by the Mana Board of Directors and approved by the Mana stockholders in connection with the Business Combination.

The 2022 Plan, as approved, permitted the issuance of up to 108,850 shares (3,265,516 prior to the Reverse Stock Split) of Common Stock (the “Share Reserve”) upon exercise or conversion of grants and awards made from time to time to officers, directors, employees and consultants, provided, however that the Share Reserve will increase on January 1st of each calendar year and ending on and including January 1, 2027 (each, an “Evergreen Date”), in an amount equal to the lesser of (i) 7% of the total number of shares of Common Stock outstanding on the December 31st immediately preceding the applicable Evergreen Date and (ii) such lesser number of shares of Common Stock as determined to be appropriate by the Compensation Committee, which administers the 2022 Plan, in its sole discretion.

Each option has an exercise price of $63.30 per share ($2.11 prior to the Reverse Stock Split) with an expiration date of January 23, 2034. For the remaining 700 options (21,000 prior to the Reverse Stock Split), 250 options (7,500 prior to the Reverse Stock Split) were vested on June 30, 2024, 167 options (5,000 prior to the Reverse Stock Split) were vested on December 31, 2024 and 283 options (8,500 prior to the Reverse Stock Split) were forfeited before vesting with the leaving of the employees before December 31, 2024.

Equity Award Grant Practices

Our equity-based incentive awards are designed to align our interests and the interests of our stockholders with those of our employees and consultants, including our Named Executive Officers. The Board or Compensation Committee is responsible for approving equity grants. We typically grant equity awards to new hires or employees receiving bonuses annually for the previous fiscal year’s performance. Annual awards are typically granted in the first quarter of each year. Generally, our equity awards granted to our Named Executive Officers vest over four years, subject to the employee’s continued employment with us on each vesting date. The independent board of directors annual compensation is paid 50% in the form of stock options, payable quarterly. The regularly-scheduled grant dates for the independent board of directors stock options are the last calendar day of the each fiscal quarter.

The Board and Compensation Committee does not take material nonpublic information into account when determining the timing and terms of equity-based awards, and the Company does not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation. For all stock option awards, the exercise price is the closing price of our Common Stock on the Nasdaq Capital Market on the date of the grant. If the grant date falls on a non-trading day, the exercise price is the closing price of our Common Stock on the Nasdaq Capital Market on the last trading day preceding the date of grant. We have not timed the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation for any Named Executive Officer grants in fiscal year 2025.

Other Elements of Compensation

Retirement Plan

We maintain a 401(k) retirement savings plan for our employees, including our named executive officers, who satisfy certain eligibility requirements. The Internal Revenue Code allows eligible employees to defer a portion of their compensation, within prescribed limits, on a pre-tax basis through contributions to the 401(k) plan. We believe that providing a vehicle for tax- deferred retirement savings though our 401(k) plan adds to the overall desirability of our executive compensation package and further incentivizes our employees, including our named executive officers, in accordance with our compensation policies.

Employee Benefits and Perquisites

Health/Welfare Plans. All of our full-time employees, including our named executive officers, are eligible to participate in our health and welfare plans, including:

•

medical, dental and vision benefits;

•

medical and dependent care flexible spending accounts;

•

life insurance and accidental death and dismemberment;

We believe the benefits described above are necessary and appropriate to provide a competitive compensation package to our employees, including our named executive officers. We do not provide any perquisites to our named executive officers.

No Tax Gross-Ups

We do not make gross-up payments to cover our named executive officers’ personal income taxes that may pertain to any of the compensation or benefits paid or provided by our Company.

Outstanding Equity Awards at Fiscal Year-End Table

The following table summarizes the number of shares of common stock underlying outstanding equity incentive plan awards for each named executive officer as of December 31, 2025. We have made no stock awards under the 2022 Plan and accordingly, that portion of the table has been omitted.

Agreements with Our Executive Officers and Non-Executive Chairman of the Board

In connection with preparations for the Business Combination, Cardio executed employment agreements as of May 27, 2022 with each person expected to be named an executive officer of the combined entity. The agreements became effective upon Closing of the Business Combination in October 2022. The principal terms of each of agreements is as follows:

Employment Agreement between Cardio and Meeshanthini V. Dogan (Chief Executive Officer)

Dr. Dogan’s five-year employment agreement provides for (i) an annual base salary of $300,000, (ii) eligibility to receive an annual cash bonus based on the extent to which, in the discretion of the Board, Dr. Dogan achieves or exceeds specific and measurable individual and Company performance objectives, and (iii) eligibility to participate in any long-term incentive plan that is made available to similarly positioned executives, employee benefit or group insurance plans maintained from time to time by Cardio. Long-term incentive plan awards may include cash, or equity awards settled in shares of Company stock, including but not limited to stock options, restricted stock and performance shares. If Dr. Dogan were to leave the Company as a "Good Leaver,” as defined in the employment agreement, terms of any long-term incentive award will be deemed satisfied immediately prior to such termination and as such, all awards and grants will be deemed fully vested. In addition, Dr. Dogan will be reimbursed for her reasonable and usual business expenses incurred on behalf of the Company. Severance benefits will be payable in the event Dr. Dogan’s termination is either by the Company without cause or by her with "good reason,” as defined in the agreement. In such event and in addition to accrued salary benefits as of the date of termination, the Company will pay Dr. Dogan an amount equal to a (x) two times the sum of her most recent base salary and target annual bonus and (y) an amount in cash equal to the Company’s premium amounts paid for her coverage under group medical, dental and vision programs for a period of 24 months. The agreement also contains customary confidentiality, non- solicitation, non-competition and cooperation provisions. The employment agreement will automatically renew for an additional year following the initial term and any renewal term, unless either party provides 60-days’ written notice before the end of the then-current term. The Company may terminate Dr. Dogan’s employment without cause (as defined in the agreement) by providing 60 days’ advance written notice. Dr. Dogan may terminate her employment for any reason.

Non-Executive Chairman and Consulting Agreement between Cardio and Warren Hosseinion

Cardio has retained Dr. Hosseinion under a five-year consulting agreement to serve as Non-Executive Chairman of the Board following the Merger and to provide other services as requested. Upon expiration of such provision, the agreement may be renewed for an additional one-year term. In addition to his duties as Chairman, the agreement provides that Dr. Hosseinion will provide consulting services assisting management in developing business strategy and business plans, identifying business opportunities and identifying strategic relationships and strategies to further develop the Company’s brand. In the event he is not reelected as Chairman of the Board, the terms of this agreement will continue strictly as a consulting services agreement.

Conversely, if his consulting services are terminated, such termination will not affect his Chairman Services, provided that he remains eligible to serve as Chairman. For his Chairman services and consulting services, the agreement provides for a fee of $300,000 per year payable in monthly installments of $25,000. In addition, Dr. Hosseinion is entitled to be awarded any equity compensation otherwise payable to Board members in connection with their service on the Board and to be reimbursed for all reasonable and necessary business expenses incurred in the performance of his consulting services and Chairman services. If Dr. Hosseinion’s services are terminated by the Company other than for Cause (as defined in the agreement), including any discharge without Cause, liquidation or dissolution of the Company, or a termination caused by death or Disability (as defined in the agreement), the Company will pay Dr. Hosseinion (or his estate) the consulting fees equal to two times his annual consulting compensation, payable within 60 days, in one lump sum, plus any expenses owing for periods prior to and including the date of termination of the consulting services. The agreement also contains customary confidentiality, non-solicitation, non-disparagement and cooperation provisions. Either party may terminate the agreement without cause after giving prior written notice to the other party. The agreement may be terminated by the Company at any time for cause, as defined in the agreement.

Employment Agreement between Cardio and Elisa Luqman (Chief Financial Officer)

Ms. Luqman’s five-year employment agreement provides for (i) an annual base salary of $275,000, (ii) eligibility to receive an annual cash bonus based on the extent to which, in the discretion of the Board, Ms. Luqman achieves or exceeds specific and measurable individual and Company performance objectives, and (iii) eligibility to participate in any long-term incentive plan that is made available to similarly positioned executives, employee benefit or group insurance plans maintained from time to time by Cardio. Long-term incentive plan awards may include cash, or equity awards settled in shares of Company stock, including but not limited to stock options, restricted stock and performance shares. If Ms. Luqman were to leave the Company as a "Good Leaver,” as defined in the employment agreement, terms of any long-term incentive award will be deemed satisfied immediately prior to such termination and as such, all awards and grants will be deemed fully vested. In addition, Ms. Luqman will be reimbursed for her reasonable and usual business expenses incurred on behalf of the Company. Severance benefits will be payable in the event Ms. Luqman’s termination is either by the Company without cause or by her with "good reason,” as defined in the agreement.

The agreement also contains customary confidentiality, non-solicitation, non-competition and cooperation provisions. The employment agreement will automatically renew for an additional year following the initial term and any renewal term, unless either party provides 60-days’ written notice before the end of the then-current term.
