NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Organization and Summary of Significant Accounting Policies

The condensed consolidated financial statements include the accounts of SINTX Technologies, Inc. (“SINTX”, or the “Company”) and its wholly-owned subsidiaries, SINTX Armor, Inc. (“SINTX Armor”), SINTX Agribiotech, Inc., and Technology Assessment and Transfer, Inc. (TA&T) through February 19, 2025 (see Note 2), which are collectively referred to as “we” or the “Company.” SINTX Technologies is an advanced ceramics company formed in December 1996, that develops and commercializes materials, components, and technologies for medical and agribiotech applications. SINTX provides biomedical solutions for medical devices specializing in silicon nitride (Si₃N₄) for musculoskeletal and antipathogenic applications. SINTX is a global leader in the research, development, and manufacturing of silicon nitride, and its products have been implanted in humans since 2008.

SINTX Core Business

Biomedical Applications: Since its inception, SINTX has been focused on medical grade silicon nitride. SINTX biomedical products have been shown to be biocompatible, bioactive, antipathogenic, and to have superb bone affinity. Spinal implants made from SINTX silicon nitride have been successfully implanted in humans since 2008 in the U.S., Europe, South America and Asia. This established use, along with its inherent resistance to bacterial adhesion and bone affinity suggests that it may also be suitable in other fusion device applications such as arthroplasty implants, foot wedges, and dental implants. More recently, in July 2025, SINTX submitted a 510(k) premarket notification to the U.S. Food and Drug Administration (FDA) for its novel silicon nitride osteotomy wedges, marking its official entry into the foot and ankle reconstruction market. These next-generation implants blend cutting-edge biomaterials science with surgical precision and are designed to elevate standards in orthopedic procedures. SINTX silicon nitride products can be polished to a smooth and wear-resistant surface for articulating applications, such as bearings for hip and knee replacements.

We believe that silicon nitride has a superb combination of properties that make it suited for long-term human implantation. Other biomaterials are based on bone grafts, metal alloys, and polymers- all of which have well-known practical limitations and disadvantages. In contrast, silicon nitride has a legacy of success in the most demanding and extreme industrial environments. Bacterial infection of any biomaterial implants is always a concern. SINTX silicon nitride has been shown to be resistant to bacterial colonization and biofilm formation, making it antibacterial. As a human implant material, silicon nitride offers bone ingrowth, resistance to bacterial and viral infection, ease of diagnostic imaging, resistance to corrosion, and superior strength and fracture resistance, all of which claims are validated in our large and growing inventory of peer-reviewed, published literature reports. We believe that our versatile silicon nitride manufacturing expertise positions us favorably to introduce new and innovative devices in the medical and non-medical fields.

Antipathogenic Applications: Today, there is a global need to improve protection against pathogens in everyday life. SINTX believes that by incorporating its unique composition of silicon nitride antipathogenic powder into products such as face masks, drapes, filters, sutures, and wound care devices, it is possible to manufacture surfaces that inactivate pathogens, thereby limiting the spread of infection and disease. The discovery in 2020 that SINTX silicon nitride inactivates SARS-CoV-2, the virus which causes the disease COVID-19, has opened new markets and applications for our material. We presently manufacture advanced ceramic powders and components in our manufacturing facilities based in Salt Lake City, Utah.

The SINTX Salt Lake City facility is registered with the FDA, is cGMP and ANVISA RDC 665 compliant, as well as being ISO 9001:2015, ISO 13485:2016 certified, and ASD9100D certified. The Company’s products are primarily sold in the United States.

Basis of Presentation

These unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the United States Securities and Exchange Commission (“SEC”) and include all assets and liabilities of the Company.

SEC rules and regulations allow the omission of certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) so long as the statements are not misleading. In the opinion of management, these financial statements and accompanying notes contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly the financial position and results of operations for the periods presented herein. These condensed consolidated financial statements should be read in conjunction with the consolidated audited financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on March 19, 2025. The results of operations for the six months ended June 30, 2025, are not necessarily indicative of the results to be expected for the year ending December 31, 2025. The Company’s significant accounting policies are set forth in Note 1 to the consolidated financial statements in its Annual Report on Form 10-K for the year ended December 31, 2024.

Segment Information

The Company operates as one operating segment. Operating segments are defined as components of an entity for which separate financial information is regularly evaluated by the chief operating decision maker (“CODM”), which is the Company’s Chief Executive Officer, in deciding how to allocate resources and assess performance. The Company’s CODM evaluates financial information and resources and assesses the performance of these resources on a consolidated basis. There is no expense or asset information that is supplemental to information disclosed within the consolidated financial statements, that is regularly provided to the CODM. The allocation of resources and assessment of performance of the operating segment is based on consolidated net loss and functional expenses as reported on our condensed consolidated statements of operations and comprehensive loss. Because the Company operates as one operating segment, financial segment information, including expense and asset information, can be found in the condensed consolidated financial statements.

Reverse Stock Split

On May 28, 2024, the Company effected a 1 for 200 reverse stock split of the Company’s common stock. The par value and the authorized shares of the common and preferred stock were not adjusted as a result of the reverse stock split. All common stock shares, equivalents, and per-share amounts for all periods presented in these condensed consolidated financial statements have been adjusted retroactively to reflect the reverse stock split.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP 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 condensed consolidated financial statements and the reported amounts of revenue and expenses during the period. Actual results could differ from those estimates. As of June 30, 2025, the most significant estimate relates to derivative liabilities relating to common stock warrants.

Liquidity and Capital Resources

The condensed consolidated financial statements have been prepared assuming the Company will continue to operate as a going concern, which contemplates the realization of assets and settlement of liabilities in the normal course of business, and does not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from uncertainty related to its ability to continue as a going concern within one year from the date of issuance of these condensed consolidated financial statements.

For the six months ended June 30, 2025, and 2024, the Company incurred a net loss of $4.6 million and $3.1 million, respectively, and used cash in operating activities of $3.7 million and $4.9 million, respectively. The Company had an accumulated deficit of $286 million and $282 million as of June 30, 2025, and December 31, 2024, respectively. We will require substantial future capital in order to continue operating our business, conduct research and development and regulatory clearance and approval activities necessary to bring our products to market, and to establish effective marketing and sales capabilities. Our existing capital resources are not sufficient to enable us to fund the completion of the development and commercialization of all our product candidates.

To date, the Company’s operations have been principally financed from proceeds from the issuance of preferred and common stock and, to a lesser extent, cash generated from product sales. It is anticipated that the Company will continue to generate operating losses and use cash in operations. The Company’s continuation as a going concern is dependent upon its ability to increase sales, decrease expenses and raise additional funding. Whether and when the Company can attain profitability and positive cash flows from operations or obtain additional financing is uncertain.

We are actively seeking opportunities to raise additional equity and/or debt financing. However, such funding is not guaranteed and may not be available to the Company on favorable or acceptable terms and may involve significant restrictive covenants. Any additional equity financing, if available to the Company, will most likely be dilutive to its current stockholders. If the Company is not able to obtain additional debt or equity financing on a timely basis, the impact on the Company will be material and adverse.

The Board of Directors, together with management, is performing an ongoing evaluation of the Company’s business strategy and focus.

The Company’s strategic emphasis is focused on utilizing its technology in making advancements in the biomedical sector. Historically engaged in both industrial and biomedical applications, SINTX has prioritized the development and commercialization of innovative medical devices, leveraging its expertise in advanced ceramics and biomaterials. This renewed focus aligns with a commitment to improving patient outcomes through the creation of products designed for surgical, orthopedic, and other specialized medical applications. We are concentrating our resources on high-growth areas within the healthcare sector where our proprietary materials and technologies—such as silicon nitride—provide a distinct competitive advantage due to their unique strength, durability, and biocompatibility.

Through this transformation, SINTX’s aim is to deliver meaningful innovations to the medical community. Our current research and development pipeline is centered on medical-grade devices that incorporate antimicrobial properties, enhanced imaging capabilities, and durability under physiological conditions, which are critical for orthopedic implants, spinal fusion devices, and other surgical tools. As we transition our focus away from industrial applications, we anticipate this strategic shift will enable us to better serve the medical sector, address critical unmet needs, and position SINTX as a leading provider in the medical device market. By focusing on partnerships and collaborations with healthcare institutions and industry leaders, SINTX is positioned to expand its footprint in the medical device sector and drive shareholder value through sustainable, high-impact innovations.

On August 8, 2024, the Board of Directors approved a plan to implement a Company-wide reduction in the workforce. This decision was part of the Company’s ongoing strategic review of its operations aimed at improving operational efficiency and reducing costs.

On August 12, 2024, the Board of Directors approved a plan to cease efforts to make the armor plant operational. This decision was made to streamline operations and focus on core business areas that align with the Company’s long-term strategic goals. The armor plant has not been fully operational since the acquisition of the armor equipment in July 2021 and has been completely shut down since October 2023 due to the malfunctioning of the sintering furnace. In connection with this decision, the Company incurred an impairment charge of approximately $4.6 million during the year ended December 31, 2024. This charge primarily relates to the write-down of certain long-lived assets associated with the armor plant to their estimated fair value.

As explained in Note 2, on February 19, 2025, the Company entered into an Entity Acquisition Agreement (the “Agreement”) with Tethon Corporation (“Tethon”), pursuant to which the Company sold to Tethon all of the issued and outstanding shares of TA&T in exchange for the assumption by Tethon of the outstanding liabilities of TA&T.

As a result of these uncertainties, management has concluded that substantial doubt exists about the Company’s ability to continue as a going concern for 12 months from the date these condensed consolidated financial statements are issued. The condensed consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties.

Recent Accounting Pronouncements

ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures

In December 2023, the FASB issued ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” on the topic of income taxes. The standard requires additional disclosure for income taxes. These requirements include: (i) requiring a public entity to disclose specific categories in the rate reconciliation; (ii) disclosure of additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5% of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate); (iii) annual disclosure of the amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes; (iv) annual disclosure of the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than 5% of total income taxes paid (net of refunds received); (v) annual disclosure of income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign; and (vi) annual disclosure of income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign. For public entities, the guidance is effective for annual periods beginning after December 15, 2024. The Company will adopt this guidance in fiscal 2025 and is in the process of evaluating the new requirements. As a result, the Company has not yet determined the impact this new ASU will have on its disclosures.

ASU 2024-03, Income Statement—Reporting Comprehensive Income (Topic 220): Disaggregation of Income Statement Expenses

In November 2024, the FASB issued ASU No. 2024-03, “Income Statement—Reporting Comprehensive Income (Topic 220): Disaggregation of Income Statement Expenses,” which requires public business entities, such as the Company, to provide disaggregated disclosure of specific natural expense categories underlying certain income statement expense line items in the notes to the financial statements. The standard identifies five required natural expense categories for disaggregation—employee compensation, depreciation, amortization, inventory expense, and other manufacturing expenses—along with a residual “other” category for remaining amounts within relevant expense captions (e.g., cost of sales, selling, general and administrative expenses). ASU 2024-03 does not alter the expense captions presented on the face of the income statement but enhances footnote disclosures to improve transparency. The standard is effective for annual periods beginning after December 15, 2026, with early adoption permitted, and must be applied prospectively, though retrospective application is optional. An update in ASU 2025-01 clarified that interim period disclosures are not required until annual periods beginning after December 15, 2027. The Company is in the process of evaluating the impact of ASU 2024-03 on its consolidated financial statements. We expect adoption to necessitate modifications to our financial reporting processes and systems to capture and disclose the required disaggregated expense information in the footnotes. Management anticipates that this will enhance the granularity of expense disclosures but does not expect a material effect on our reported financial position or results of operations. We are reviewing our current expense classification practices and data collection capabilities to ensure compliance with the new requirements upon adoption.

The Company has determined that recently issued accounting standards, other than the above discussed, will not have a material impact on its consolidated financial position, results of operations or cash flows.

2. Disposition of TA&T

On February 19, 2025, the Company entered into an Entity Acquisition Agreement (the “Agreement”) with Tethon Corporation (“Tethon”), pursuant to which the Company sold to Tethon all of the issued and outstanding shares of TA&T in exchange for the assumption by Tethon of the outstanding liabilities of TA&T. The disposal did not represent a strategic shift that will have a major effect on the Company’s operations and financials and, therefore, did not qualify for discontinued operations treatment under ASC 205-20.

The following table summarizes the carrying amounts of the major classes of assets and liabilities of TA&T at the date of sale that were transferred to the Tethon (in thousands):

	February 19, 2025
Cash and cash equivalents	$	4
Inventories		8
Accounts receivable		91
Right of use asset		376
Property and equipment, net		248
Other assets		16
Total assets sold		743
Accounts payable		(26	)
Accrued expenses		(275	)
Operating lease liability		(384	)
Other liabilities		(34	)
Total liabilities assumed		(719	)
Net assets sold	$	24

No consideration was paid other than the assumption by Tethon of the above liabilities. No significant transaction costs were incurred. No earnout or other contingent consideration arrangements were included in the Agreement.

3. Basic and Diluted Net Income (Loss) per Common Share

Basic net income (loss) per share is calculated by dividing the net income (loss) by the weighted-average number of common shares outstanding for the period, without consideration for common stock equivalents. Diluted net loss per share is calculated by dividing the net loss by the weighted-average number of common share equivalents outstanding for the period that are determined to be dilutive. Common stock equivalents are primarily comprised of preferred stock and warrants for the purchase of common stock. The Company had potentially dilutive securities of approximately 2.1 million and 0.1 million as of June 30, 2025, and 2024, respectively, that were not included in the fully diluted loss per share calculation because they would have been antidilutive.

Below are basic and diluted loss per share data for the three months ended June 30, 2025, which are in thousands except for share and per share data:

5. Fair Value Measurements

Financial Instruments Measured and Recorded at Fair Value on a Recurring Basis

The Company has issued certain warrants to purchase shares of common stock, which are considered derivative liabilities because they have certain rights which could require a cash settlement and are re-measured to fair value at each reporting period in accordance with accounting guidance. Fair value is based on the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, under a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value as follows:

	Level 1 -	quoted market prices for identical assets or liabilities in active markets.

	Level 2 -	observable prices that are based on inputs not quoted on active markets but corroborated by market data.

	Level 3 -	unobservable inputs reflecting management’s assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.

The Company classifies assets and liabilities measured at fair value in their entirety based on the lowest level of input that is significant to their fair value measurement. No financial assets or liabilities (except the derivative liabilities explained above) were measured on a recurring basis as of June 30, 2025, and December 31, 2024. The following tables set forth the financial liabilities measured at fair value on a recurring basis by level within the fair value hierarchy as of June 30, 2025, and December 31, 2024 (in thousands):

	Fair Value Measurements as of June 30, 2025
Description	Level 1		Level 2		Level 3		Total
Derivative liabilities:
Common stock warrants	$	-	$	-	$	160	$	160

The Company did not have any transfers of assets and liabilities between Level 1 and Level 2 of the fair value measurement hierarchy during the six months ended June 30, 2025, and 2024. The following table presents a reconciliation of the derivative liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the six months ended June 30, 2025, and 2024 (in thousands):

Common Stock Warrants

The Company has issued certain warrants to purchase shares of common stock, which are considered derivative liabilities because they have registration rights which could require a cash settlement and are re-measured to fair value at each reporting period in accordance with accounting guidance. As of June 30, 2025, and December 31, 2024, the derivative liability was calculated using the Monte Carlo Simulation valuation.

The assumptions used in estimating the common stock warrant liability using the Monte Carlo simulation valuation model as of June 30, 2025, and December 31, 2024 were as follows:

	June 30, 2025		December 31, 2024
Weighted-average risk-free interest rate	3.66-3.92	%	4.12-4.35	%
Weighted-average expected life (in years)	0.09-3.59		0.10-4.09
Expected dividend yield	-	%	-	%
Weighted-average expected volatility	140.00-165.00	%	140.00-210.00	%

Other Financial Instruments

The Company’s recorded values of cash and cash equivalents, account and other receivables, accounts payable and accrued liabilities approximate their fair values based on their short-term nature. The recorded value of notes payable approximates the fair value as the interest rate approximates market interest rates.

6. Accrued and Other Current Liabilities

Accrued liabilities consisted of the following (in thousands):

	June 30, 2025		December 31, 2024
Payroll and related expense	$	215	$	400
Accrued payables		10		178
Other		360		408
Accrued other liabilities	$	585	$	986

SINTX Core Business

Components of our Results of Operations

We manage our business within one reportable segment, which is consistent with how our management reviews our business, makes investment and resource allocation decisions, and assesses operating performance.

Revenue

Our product revenue is derived from the manufacture and sale of products. These revenue sources primarily include coatings, materials, and components for aerospace and medical device markets, toll processing services, and government contracts and grants. We generally recognize revenue from sales where control transfers at a point in time as the title and risk of loss passes to the customer, which is at the time the product is shipped. In general, our customer does not have rights of return or exchange.

We believe our product revenue will increase as we complete development and obtain regulatory clearance for our product candidates and secure opportunities to manufacture third party products with silicon nitride.

We also derive grant and contract revenue from awards provided by governmental agencies.

Cost of revenue

The expenses that are included in cost of revenue include all in-house manufacturing costs for the products we manufacture.

Gross profit

Our gross profit measures our product revenue relative to our cost of revenue.

Research and development expenses

Our research and development costs are expensed as incurred. Research and development costs consist of engineering, product development, clinical trials, test-part manufacturing, testing, developing and validating the manufacturing process, manufacturing, facility and regulatory-related costs. Research and development expenses also include employee compensation, employee and non-employee stock-based compensation, supplies and materials, consultant services, and travel and facilities expenses related to research and development activities.

We expect to incur additional research and development costs as we continue to develop new medical devices, related product candidates for antipathogenic applications, and other products which may increase our total research and development expenses.

General and administrative expenses

General and administrative expenses consist primarily of salaries, benefits and other related costs, including stock-based compensation for certain members of our executive team and other personnel employed in finance, legal, compliance, administrative, information technology, customer service, executive and human resource departments. General and administrative expenses also include other expenses not part of the other cost categories mentioned above, including facility expenses and professional fees for accounting and legal services.

Revenue

For the three months ended June 30, 2025, product revenue decreased $0.3 million, or 74%, compared to the same period in 2024. During the three months ended June 30, 2025, grant and contract revenue decreased $0.4 million, or 89% as compared to the same period in 2024.

For the six months ended June 30, 2025, product revenue decreased $0.3 million, or 43%, compared to the same period in 2024. During the six months ended June 30, 2025, grant and contract revenue decreased $0.7 million, or 85% as compared to the same period in 2024.

Revenue trends and strategic focus

The decrease in total revenue for the two periods was primarily due to the Company’s ongoing strategic repositioning away from non-core, low-margin OEM technical manufacturing contracts that did not support long-term profitability. This planned reduction in OEM-related revenue is consistent with our corporate shift toward commercializing proprietary silicon nitride-based biomedical devices, which we believe offer stronger margins, a more defensible competitive position, and better long-term value for shareholders.

While this strategic realignment has led to a temporary minor decline in reported revenue, we believe it is a necessary step in positioning the Company for sustainable growth. During this transitional period, we continue to invest in the development and regulatory advancement of silicon nitride-based orthopedic and surgical implants, as evidenced by our recently submitted 510(k) for osteotomy wedges used in foot and ankle fusion procedures. We believe that these products will serve as key revenue drivers in the future.

Net cash used in operating activities

Net cash used in operating activities was $3.7 million during the six months ended June 30, 2025, compared to $4.9 million used during the six months ended June 30, 2024, a decrease of $1.2 million. Decrease in net loss of $1.5 million, combined with adjustments of non-cash items of $2.9 million, and an increase in other liabilities of $0.8 million, contributed positively to our net cash used in operating activities, partially offset by increases in accounts receivable of $0.2 million and prepaid expenses of $0.7 million.

Net cash provided by (used in) investing activities

Net cash provided by investing activities was $0.3 million during the six months ended June 30, 2025, compared to net cash used in investing activities of $0.2 million during the six months ended June 30, 2024, an increase of $0.5 million. The increase in cash provided by investing activities during 2025 was primarily due to a $0.5 million decrease in purchase of property and equipment and a $0.3 million increase in proceeds from the sale of property and equipment, partially offset by a $0.3 million decrease in proceeds from notes receivable.

Net cash provided by financing activities

There was $4.1 million in cash provided by financing activities during the six months ended June 30, 2025, compared to $6.3 million in cash provided by financing activities during the same period in 2024. The $2.2 million decrease to net cash provided by financing activities was primarily attributable to a decrease in proceeds from issuance of warrant derivative liabilities of $3.4 million offset by an increase in proceeds from issuance of common stock and prefunded warrants of $1.3 million.
