Note 1. Description of Business and Summary of Significant Accounting Policies

Description of Business

In this quarterly report on Form 10-Q, Mesa Laboratories, Inc., a Colorado corporation, together with its subsidiaries, is collectively referred to as “we,” “us,” “our,” the “Company,” or “Mesa.”

We are a global leader in the design and manufacture of life sciences tools and critical quality control solutions for regulated applications in the pharmaceutical, healthcare and medical device industries. We offer products and services to help our customers ensure product integrity, increase patient and worker safety, and improve the quality of life throughout the world. We have manufacturing operations in the United States and Europe, and our products are marketed by our sales personnel in North America, Europe and Asia Pacific, and by independent distributors throughout the world.

As of June 30, 2025, we managed our operations in four reportable segments, or divisions:

	●	Sterilization and Disinfection Control - manufactures and sells biological, chemical and cleaning indicators used to assess the effectiveness of sterilization, decontamination, disinfection and cleaning processes in the pharmaceutical, medical device and healthcare industries. The division also provides testing and laboratory services, mainly to the dental and pharmaceutical industries.

	●	Biopharmaceutical Development - develops, manufactures, sells and services automated systems for protein analysis (immunoassays) and peptide synthesis solutions. Immunoassays and peptide synthesis solutions accelerate the discovery, development and manufacture of biotherapeutic therapies, among other applications.

	●	Calibration Solutions - develops, manufactures, sells and services quality control products using principles of advanced metrology to enable customers to measure and calibrate critical parameters in applications such as renal care, environmental and process monitoring, gas flow and torque testing.

●

Clinical Genomics - develops, manufactures and sells highly sensitive high-throughput genetic analysis tools and related consumables and services that enable clinical research labs and contract research organizations to perform genomic testing for a broad range of research applications in several therapeutic areas, such as screenings for hereditary diseases, pharmacogenetics, oncology related applications and toxicology research.

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission and in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information. In the opinion of management, such unaudited information includes all adjustments, consisting of normal recurring adjustments, necessary for the fair statement of our financial position and results of operations. The results of operations for interim periods are not necessarily indicative of results that may be achieved for the entire year. The year-end Condensed Consolidated Balance Sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. The Condensed Consolidated Financial Statements include the accounts of Mesa and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. We made no material changes to the application of our significant accounting policies disclosed in our annual report on Form 10-K. This report should be read in conjunction with the consolidated financial statements included in our Annual Report on Form 10-K for the year ended March 31, 2025.

Our fiscal year ends on March 31. References in this report to a particular “year” or “quarter” refer to our fiscal year or fiscal quarters, respectively.

Risks and Uncertainties

The preparation of financial statements requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities at the reporting date and revenues and expenses during the reporting periods. These estimates represent management's judgment about the outcome of future events. The global business environment continues to be impacted by cost pressures, the overall effects of economic uncertainty, regulatory changes, and other factors. Changes in, and the resulting effects of, potential government trade, stimulus or fiscal and monetary policies, interest rates, foreign currency values, supply chains, demand for goods and services, global or regional recession, or other circumstances cannot be reliably predicted. Actual results could differ from our estimates.

Recent Accounting Pronouncements

We have reviewed all recently issued accounting pronouncements and have concluded that, other than as described below, they are either not applicable to us or are not expected to have a significant impact on our consolidated financial statements. We have not adopted any new accounting standards in fiscal year 2026.

Recently Issued Accounting Pronouncements

In December 2023, the FASB issued ASU No. 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures." ASU No. 2023-09, which enhances the transparency, effectiveness and comparability of income tax disclosures by requiring consistent categories and greater disaggregation of information related to income tax rate reconciliations and the jurisdictions in which income taxes are paid. The guidance is effective for public business entities for fiscal years beginning after December 15, 2024 (our fiscal year 2026), with early adoption and prospective or retrospective application permitted. Other than presentation of additional disaggregated data in our income tax footnote disclosures for annual periods, we do not expect the adoption of ASU No. 2023-09 to have a material impact on our consolidated financial statements and disclosures.

In November 2024, the FASB issued ASU No. 2024-03, "Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses." ASU No. 2024-03 requires that public business entities disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. The ASU is effective for fiscal years beginning after December 15, 2026 (our fiscal year 2028 for annual periods) and interim periods within fiscal years beginning after December 15, 2027 (our fiscal year 2029 for interim periods), with early adoption and prospective or retrospective application permitted. We are currently assessing the effect the adoption of this standard will have on our consolidated financial statements and disclosures, and we currently expect to increase the level of disclosed detail once adopted.

Note 2. Revenue

We develop, manufacture, market, sell and maintain life sciences tools and quality control instruments and related consumables.

Hardware sales include physical products such as instruments used for molecular and genetic analysis, protein synthesizers, medical meters, wireless sensor systems, data loggers, and process challenge devices. Hardware sales may be offered with accompanying perpetual or annual software licenses, which in some cases are required for the hardware to function.

Consumables are single-use products and require frequent replacement in our customers' operating cycles. Consumables sold by our Clinical Genomics and Biopharmaceutical Development divisions, such as reagents used for molecular and genetic analysis or solutions used for protein synthesis, are critical to the ongoing use of our instruments. Consumables such as biological and chemical indicator test strips sold by our Sterilization and Disinfection Control division are used on a standalone basis.

Revenues from hardware and consumables are recognized upon transfer to the customer, typically at the point of shipment.

We also offer maintenance, calibration and testing services. Services result in revenues recognized over time, for example, when we are obligated to perform labor and replace parts on an as-needed basis over a contractually specified period of time, or at a point in time, upon completion of a specific, discrete service.

We evaluate our revenues internally based on business division and the nature of goods and services provided.

Total revenues	$	22,957	$	12,008	$	11,801	$	11,404	$	58,170

Revenues from external customers are attributed to individual countries based on the locations to which the products are shipped or exported, or locations where services are performed, as follows:

	*Three Months Ended June 30,*
	*2025*		*2024*
United States	$	27,646	$	26,861
China		5,429		6,559
Other		26,468		24,750
Total revenues	$	59,543	$	58,170

No foreign country exceeded 10% of total revenues for the three months ended June 30, 2025.

Contract Balances

Our contracts have varying payment terms and conditions. Some customers prepay for products and services resulting in unearned revenues or customer deposits called contract liabilities, which are included within unearned revenues or other noncurrent liabilities in the accompanying unaudited Condensed Consolidated Balance Sheets. The significant majority of our revenues, related receivables and contract liabilities are generated from contracts with customers with original durations of 12 months or less. Contract liabilities will be recognized as revenue as we satisfy our obligations under the terms of the contracts.

A summary of contract liabilities is as follows:

Contract liabilities as of March 31, 2025	$	14,803
Prior year liabilities recognized in revenues during the three months ended June 30, 2025		(4,385	)
Contract liabilities added during the three months ended June 30, 2025, net of revenues recognized		4,669
Contract liabilities as of June 30, 2025	$	15,087

Note 3. Fair Value Measurements

Our financial instruments consist primarily of cash and cash equivalents, trade accounts receivable, obligations under trade accounts payable, and debt. Due to their short-term nature, the carrying values for cash and cash equivalents, trade accounts receivable, and trade accounts payable approximate fair value; they are classified within Level 1 of the fair value hierarchy.

The financial instruments that subject us to the highest concentrations of credit risk are cash and accounts receivable. We maintain relationships and cash deposits at multiple banking institutions across the world in an effort to diversify and reduce risk of loss. Concentration of credit risk with respect to accounts receivable is limited to customers to whom we make significant sales. No customers accounted for more than 10% of total trade receivables as of June 30, 2025.

On April 5, 2024, we entered into separate, privately negotiated purchase agreements with a limited number of holders of our 1.375% convertible notes due August 15, 2025 (the "Notes"), through which we repurchased $75,000 in aggregate principal amount of the Notes. See Note 6. "Indebtedness" for further information. As of June 30, 2025, we had remaining outstanding $97,500 aggregate principal amount of the Notes. We estimate the fair value of the Notes using Level 2 inputs based on the last actively traded price or observable market input preceding the end of the reporting period. The fair value of the Notes is approximately correlated to our stock price.

The estimated fair value and carrying amount of the Notes were as follows:

	*June 30, 2025*				*March 31, 2025*
	*Carrying Value*		*Fair Value (Level 2)*		*Carrying Value*		*Fair Value (Level 2)*
Notes	$	97,432	$	96,708	$	97,297	$	95,063

The carrying amounts of our term loan and revolving line of credit (together, the "Credit Facility") approximate fair value due to the variable interest rate pricing on the debt, with the balance bearing an interest rate approximating current market rates.

There were no nonrecurring fair value adjustments or transfers between the levels of the fair value hierarchy during the three months ended June 30, 2025.

Note 6. Indebtedness

Credit Facility

Our senior secured credit agreement, as previously amended, includes:

(i)		A revolving credit facility with an aggregate principal amount of up to $125,000 (the "Revolver"),
(ii)		A term loan with a maximum principal amount of $75,000, which is subject to escalating quarterly principal payments (the "Term Loan"),
(iii)		A swingline loan with an aggregate principal amount not exceeding $5,000, and
(iv)		Letters of credit with an aggregate stated amount not exceeding $2,500 at any time.

We refer to the agreement in whole as the “Credit Facility.” The Credit Facility matures in April 2029 and allows us to use proceeds from borrowings to redeem some or all of our Notes.

Amounts borrowed under the Credit Facility bear interest at either a base rate or a SOFR rate plus an applicable spread ranging from 1.5% to 3.5%, depending on our total net leverage ratio. The weighted average interest rate on borrowings under the Credit Facility as of June 30, 2025 was 7.2%.

The financial covenants in the Credit Facility include a maximum leverage ratio of 4.0 to 1.0 on each of the testing dates between March 31, 2025 and March 31, 2026 and 3.5 to 1.0 on each testing date thereafter. The Credit Facility also stipulates a minimum fixed charge coverage ratio of 1.25 to 1.0 and a maximum senior net leverage ratio of 3.5 to 1. Other covenants include restrictions on our ability to incur debt, grant liens, make fundamental changes to our business as defined in the contract, engage in certain transactions with affiliates, or conduct asset sales. As of June 30, 2025, we were in compliance with all covenants under the Credit Facility.

Term Loan

We borrowed $75,000 under the Term Loan on April 5, 2024, to fund the privately negotiated repurchases of a portion of our Notes (see “Convertible Notes” below). During the three months ended June 30, 2025, we made required quarterly principal payments on the Term Loan of $938.

We are required to make quarterly principal payments on the Term Loan. For the following fiscal years ending March 31, future debt payments on the Term Loan are required as follows:

Fiscal Year	*Amount*
Remainder of 2026	$	2,813
2027		5,625
2028		5,625
2029		7,500
2030		48,750
Total principal remaining	$	70,313

The net carrying amount of the Term Loan was as follows:

	*June 30, 2025*			*March 31, 2025*
Term Loan	$	70,313		$	71,250
Less: discount and debt issuance costs		(561	)		(598	)
Less: current portion		(4,219	)		(3,750	)
Noncurrent portion	$	65,533		$	66,902

We recognized interest expense on the Term Loan as follows:

	*Three Months Ended June 30,*
	*2025*		*2024*
Interest expense (7.2% and 8.4% as of June 30, 2025 and 2024, respectively)	$	1,292	$	1,439
Amortization of discount and debt issuance costs		37		35
Total interest and amortization of discount and debt issuance costs	$	1,329	$	1,474

Revolver

As of June 30, 2025, the outstanding balance under the Revolver was $14,000, and $111,000 was available for borrowing. Subsequent to June 30, 2025, we repaid an additional $3,000 on the Revolver.

We are obligated to pay quarterly unused commitment fees of between 0.20% and 0.35% of the Revolver’s aggregate principal amount, based on our leverage ratio. In July 2025, we paid $77 in unused commitment fees for the three months ended June 30, 2025.

The balance of unamortized customary lender fees related to the Revolver was $1,128 and $1,203 as of June 30, 2025 and March 31, 2025, respectively.

Convertible Notes

On August 12, 2019, we issued an aggregate principal amount of $172,500 of the Notes. The net proceeds from the Notes, after deducting underwriting discounts and commissions and other related offering expenses payable by us, were approximately $167,056. The Notes mature on August 15, 2025, unless earlier repurchased or converted, and bear interest at a rate of 1.375% payable semi-annually in arrears on February 15 and August 15 each year. The Notes are initially convertible, subject to certain conditions, at a conversion rate of 3.5273 shares of common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $283.50 per share of common stock.

On April 5, 2024, we entered into separate, privately negotiated transactions with certain holders of the Notes to repurchase $75,000 aggregate principal amount of the Notes for an aggregate repurchase price of $71,250 in cash, plus accrued and unpaid interest of $160. We accounted for the partial repurchase of the Notes as a debt extinguishment, which resulted in the recognition of a gain on extinguishment of $2,887 in other income on the unaudited Condensed Consolidated Statements of Income during the three months ended June 30, 2024. As of June 30, 2025, $97,500 in aggregate principal amount of the Notes remained outstanding, which we intend to pay using a combination of cash on hand and a draw on our Revolver.

Upon conversion, we will pay or deliver, as the case may be, cash, shares of our common stock, or a combination of both. Under the terms of the indenture, the Notes became convertible April 15, 2025, and will remain convertible until the close of business on the second scheduled trading day immediately preceding the maturity date ( August 13, 2025). No Notes have been converted as of the date of this filing. As of June 30, 2025, the Notes were classified as a current liability on our unaudited Condensed Consolidated Balance Sheets. The if-converted value of the Notes did not exceed the principal balance as of June 30, 2025.

The net carrying amount of the Notes was as follows:

	*June 30, 2025*			*March 31, 2025*
Principal outstanding	$	97,500		$	97,500
Unamortized debt issuance costs		(68	)		(203	)
Net carrying value	$	97,432		$	97,297

We recognized interest expense on the Notes as follows:

	Three Months Ended June 30,
	2025		2024
Coupon interest expense at 1.375%	$	335	$	367
Amortization of debt issuance costs		135		145
Total interest and amortization of debt issuance costs	$	470	$	512

The effective interest rate on the Notes is approximately 1.9%.

Note 7. Stockholders' Equity

Stock-Based Compensation

During the three months ended June 30, 2025, we issued time-based restricted stock units ("RSUs") and performance-based restricted stock units ("PSUs") pursuant to the Mesa Laboratories, Inc. Amended and Restated 2021 Equity Incentive Plan, which authorizes the issuance of 660 shares of common stock to eligible participants. Stock-based compensation expense is included in cost of revenues, selling, general and administrative, and research and development expense in the accompanying unaudited Condensed Consolidated Statements of Income.

The following is a summary of RSU and PSU award activity for the three months ended June 30, 2025:

	*Time-Based Restricted Stock Units*					*Performance-Based Restricted Stock Units*
	*Number of Shares*			*Weighted- Average Grant Date Fair Value per Share*		*Number of Shares*			*Weighted- Average Grant Date Fair Value per Share*
Outstanding as of March 31, 2025		145		$	106.54		85		$	166.31
Awards granted⁽¹⁾		90			95.31		44			99.56
Awards forfeited		(2	)		104.02		-			-
Awards distributed		(53	)		114.67		(4	)		174.73
Outstanding as of June 30, 2025		180		$	98.57		125		$	142.39

⁽¹⁾	Balances for PSUs granted are reflected at target.

Outstanding time-based RSUs vest and settle in shares of our common stock on a one-for-one basis. RSUs granted to employees during the three months ended June 30, 2025 vest in equal installments on June 15, 2026, June 13, 2027 and June 13, 2028. We generally recognize the expense relating to RSUs, net of estimated forfeitures, on a straight-line basis over the vesting period, or for time-based RSUs granted to participants who qualify as retirement-eligible under our plan, over a shortened service period.

We grant PSUs to certain key employees. The number of shares earned is determined at the end of each performance period based on our achievement of certain pre-defined targets in accordance with the related award agreement. Outstanding PSUs vest upon completion of service periods described in the award agreements. We recognize expense for PSUs based on the probable outcome of achieving performance targets on a straight-line basis over the service period.

During the three months ended June 30, 2025, the Compensation Committee of the Board of Directors approved a grant of 44 PSUs at target (“the FY26 PSUs”) to eligible employees. The FY26 PSUs have a grant date fair value of $99.56 per unit and are subject to both service and market-based performance conditions. The service period and market performance measurement period is from June 15, 2025 through June 15, 2028. The number of shares that will be earned based on market performance will range from 0% to 200% of the target number of shares. If the defined minimum targets are not met, no shares will vest.

As of June 30, 2025, there were 134 shares subject to options outstanding, with a weighted average exercise price per share of $190.87 and a remaining contractual life of 2.8 years. Our Compensation Committee has not granted options to any plan participants in the past two fiscal years.

Note 8. Earnings Per Share

The following table presents a reconciliation of the denominators used in the computation of basic and diluted earnings per share ("EPS"):

	*Three Months Ended June 30,*
	*2025*		*2024*
Net income available for shareholders	$	4,742	$	3,388
Weighted average outstanding shares of common stock		5,465		5,397
Dilutive effect of stock options		-		-
Dilutive effect of RSUs and PSUs		88		27
Fully diluted shares		5,553		5,424

Basic earnings per share	$	0.87	$	0.63
Diluted earnings per share	$	0.85	$	0.62

Potentially dilutive securities include stock options and unvested time and performance based RSUs (collectively "stock awards"), as well as common shares underlying our Notes. Stock awards are excluded from the calculation of diluted EPS if they are subject to performance or market conditions that have not yet been achieved as of our reporting date, or if they are antidilutive.

The following potentially dilutive securities were excluded from the calculation of diluted EPS:

	*Three Months Ended June 30,*
	*2025*		*2024*
Assumed conversion of the Notes		344		373
Stock awards that were anti-dilutive		161		209
Total securities excluded from diluted EPS		505		582

Shares underlying the Notes were excluded from the diluted EPS calculation for the three months ended June 30, 2025 and 2024 as the impact of the assumed conversion of the Notes calculated under the if-converted method was antidilutive.

Note 9. Income Taxes

We reported an income tax provision as follows:

	Three Months Ended June 30,
	2025			2024
Income tax expense	$	2,270		$	517
Effective tax rate		32.4	%		13.2	%

For interim income tax reporting, we estimate our annual effective tax rate and apply this effective tax rate to our year-to-date pre-tax income. Each quarter, our estimate of the annual effective tax rate is updated, and if the estimated effective tax rate changes, a cumulative adjustment is made. Additionally, the tax effects of significant unusual or infrequently occurring items are recognized as discrete items in the interim period in which the events occur. There is a potential for volatility in the effective tax rate due to several factors, including changes in the mix of the pre-tax income and the jurisdictions to which they relate, changes in tax laws and foreign tax holidays, settlement with taxing authorities, and foreign currency fluctuations.

The change in the effective tax rate for three months ended June 30, 2025 compared to the prior year period is primarily due to prior year valuation allowance adjustments related to our operations in Germany, as well as an increase in German statutory taxes in the current fiscal year. The effective tax rate for the three months ended June 30, 2025 differed from the statutory federal rate of 21% primarily due to the valuation allowances previously established on the U.S. deferred taxes and varying applicable tax rates in foreign jurisdictions.

In July 2025, certain key elements of the Tax Cuts and Jobs Act that were previously temporary were made permanent, including 100% bonus depreciation, the expensing of domestic research costs, and the limitation on business interest expense deductions. Accounting Standards Codification Topic 740, Income Taxes, requires the effects of enacted changes in tax laws and rates on deferred tax balances to be recognized in the period of enactment. We are currently evaluating the impact updated regulations will have on our Consolidated Financial Statements beginning in the second quarter of fiscal year 2026.

Note 10. Commitments and Contingencies

We are party to various legal proceedings arising in the ordinary course of business. As of June 30, 2025, we are not party to any legal proceeding that management believes could have a material adverse effect on our unaudited consolidated financial position, results of operations, or cash flows.

Note 11. Segment Information

Segment information is prepared on the same basis that our chief operating decision maker ("CODM"), our CEO, uses to manage our segments, evaluate financial results, and make key operating decisions. Our four reportable segments are organized primarily by the nature of the goods and services they sell. Our CODM uses segment revenues, organic revenues growth (non-GAAP), and gross profit to allocate resources and to assess segment performance. Monthly, the CODM reviews forecast-to-actual and prior-to-current period variances in segment revenue and in segment gross profit to inform decisions regarding capital and personnel deployment. Our CODM also reviews non-GAAP adjusted operating income, defined as operating income excluding non-cash items such as depreciation, amortization and stock-based compensation, to further manage operations.

The following tables set forth our segment information:

Three months ended June 30, 2025	*Sterilization and Disinfection Control*		*Biopharmaceutical Development*		*Calibration Solutions*		*Clinical Genomics*		*Total*

Overview

As of June 30, 2025, we managed our operations in four reportable segments, or divisions: Sterilization and Disinfection Control, Biopharmaceutical Development, Calibration Solutions, and Clinical Genomics. Each of our divisions is described further in "Results of Operations" below. Unallocated corporate expenses and other business activities are reported within Corporate and Other.

Page 19

Table of Contents

Corporate Strategy

We strive to create stakeholder value and further our purpose of Protecting the Vulnerable® by growing our business both organically and through acquisitions, by improving our operating efficiency, and by continuing to hire, develop and retain top talent. We commit to our purpose of Protecting the Vulnerable® every day by taking a customer-focused approach to developing, building and delivering our products and services. We serve a broad set of industries, in particular the pharmaceutical, healthcare and medical device sectors, in which the safety, quality and efficacy of products is critical. By delivering the highest quality products possible, we are committed to protecting the communities we serve.

Organic Revenues Growth

Organic revenues growth is driven by expansion of our customer base, increases in sales volumes, new product offerings and price increases, and may be affected positively or negatively by the impact of changes in foreign currency rates on our reported revenues. Our ability to increase organic revenues is affected by general economic conditions, both domestic and international, customer capital spending trends, competition, currency exchange rates, and the introduction of new products. Our policy is to price our products and services competitively and, where possible, we pass along cost increases to our customers in order to maintain our margins. We typically evaluate costs and pricing annually, with price increases effective January 1. We evaluate the need to increase prices at other times of the year in response to significant facts and circumstances that may arise, such as increases in the price of inputs to our products, or in response to changes in government or regulatory policies, for example, due to the imposition of tariffs.

Inorganic Growth - Acquisitions

Over the past decade, we have consummated a number of acquisitions of businesses, technologies, or intangibles such as customer lists, as part of our growth strategy. Our acquisitions have allowed us to expand our product offerings and the industries we serve, globalize our company, and increase the scale at which we operate. In turn, this growth affords us the ability to improve our operating efficiency, extend our customer base, and further the pursuit of our purpose: Protecting the Vulnerable®.

Improving Our Operating Efficiency

Our ongoing goal is to maximize value in our businesses by implementing efficiencies in our manufacturing, commercial, engineering and administrative operations. We achieve efficiencies using the Mesa Way, our customer-centric, lean-based system for continuously improving our operations. The Mesa Way is built on four key pillars: "Measuring What Matters" based on our customers' perspectives and setting high standards of performance; "Empowering Teams" to improve operationally and to exceed customer expectations; "Sustainably Improving" using lean-based tools designed to help us identify and prioritize the best opportunities; and "Always Learning" to continuously build knowledge and capabilities to drive long-term performance.

Our gross profit is affected by many factors, including the types of products and services sold and the geographical region in which we sell them, labor and product costs (including costs of transporting, importing and exporting goods, and associated tariffs), manufacturing efficiencies, foreign currency rates and price competition. Historically, as we have integrated acquisitions into our business and taken advantage of manufacturing efficiencies, our gross profit percentages for some products have improved. There are, however, differences in gross profit percentages between product lines, and ultimately our mix of revenues will continue to impact our overall gross profit.

We continuously pursue opportunities to improve the efficiency of our administrative functions, including through the use of process automation and artificial intelligence.

Hire, Develop, and Retain Top Talent

At the center of our organization are talented people who are capable of taking on new challenges using a team-based approach. Indeed, it is our exceptionally talented workforce that works together to find ways to continuously and sustainably improve our products, our services, and ourselves, resulting in long-term value creation for our stakeholders.

General Trends

We are a global company with multinational operations. During the three months ended June 30, 2025, approximately 54% of our revenues were earned outside of the United States. Our geographic and industry diversity presents both opportunities and challenges, including those associated with operating in varied economic environments, complying with increasing regulatory requirements including tariffs and reciprocal tariffs, navigating global labor trends and costs, adapting to technology changes in served markets, pursuing expansion opportunities in high-growth markets, and monitoring foreign currency impacts against the U.S. dollar ("USD"). Our continued revenues growth will depend on our ability to (i) expand business with new and existing customers through ongoing commercial efforts, (ii) identify, consummate and integrate acquisitions successfully, and (iii) develop or acquire differentiated products and services. We strive to maintain our profitability by improving the effectiveness of our sales force, by continuing to pursue cost reduction initiatives, and by taking a long-term strategic approach to investments in our business that we believe will support future commercial success.

During the first quarter of fiscal year 2026, our revenues increased 2.4% versus the comparable prior year period, primarily as a result of organic revenues growth in our Sterilization and Disinfection Control and Calibration Solutions divisions, partially offset by revenues declines in our Clinical Genomics and Biopharmaceutical Development divisions.

Gross profit as a percentage of revenues decreased 2.0 percentage points to 62.0% in the first quarter of fiscal year 2026 versus the comparable prior year period; however, the direct impact of tariffs on our gross profit percentage for the first quarter of fiscal year 2026 was modest. Operating expenses increased 7.0% for the three months ended June 30, 2025 versus the comparable prior year period. Changes in global markets, including the weakening of the U.S. dollar, current tariffs and inflationary pressures, and economic uncertainty during the three months ended June 30, 2025 have resulted in higher reported costs of revenues and operating expenses. We expect that the impact of current tariffs will continue to apply upward pressure on our costs. In future periods, we expect to partially offset the operating profit impact of the enacted tariff with price increases, supply chain adjustments, surcharges, and additional productivity and cost savings actions; however, we cannot predict the impact rising costs will ultimately have on our operating profits.

We source parts and materials from vendors and sell to customers throughout the world. Beginning in the first quarter of fiscal year 2026, the U.S. implemented significant tariffs on imports from a wide range of countries, which prompted retaliatory tariffs by a number of countries, resulting in some cases in a cycle of further retaliatory tariffs by both the U.S. and other countries. In early April 2025, actions were taken by the U.S. and certain other countries to delay the effective date of certain of these tariffs, but a number of the new tariffs remain in effect, including significant tariffs between the U.S. and China. In addition to changes in trade policy, there have been a number of international and domestic policy and regulatory changes in recent years that have resulted in uncertainty and in some cases, slower selling cycles for our instruments.

Our Sterilization and Disinfection Control and Calibration Solutions division benefited from strong commercial execution and increased orders in the first quarter of fiscal year 2026 compared to the same period in fiscal year 2025. Both the Biopharmaceutical Development and Clinical Genomics divisions experienced challenges presented by changing global trade and regulatory environments, including the impact of tariffs and uncertainty regarding their duration and magnitude, which contributed to delays in customer purchasing decisions.

The strengthening of foreign currencies against the U.S. dollar increases our reported revenues, gross profit margins, operating expenses and other income, and impacts the comparability of our results between periods. Conversely, the strengthening of the U.S. dollar against other major currencies would adversely impact our revenues and results of operations overall.

The Sterilization and Disinfection Control division's revenues increased 10.7% for the three months ended June 30, 2025 versus the comparable prior year period. Growth was driven by strong commercial execution resulting in increased sales volumes, and to a lesser extent, increased order fulfillments of our past due backlog as our manufacturing productivity increased, as well as the benefit of higher reported revenues as the euro strengthened against the U.S. dollar. We reduced our past due backlog by approximately $0.8 million compared to March 31, 2025.

Gross profit as a percentage of revenues increased 3.7 percentage points for three months ended June 30, 2025, primarily as a result of a $0.8 million charge for non-cash inventory step-up amortization related to the GKE acquisition that was recorded in the comparable prior year period, and to a lesser extent, favorable foreign currency impacts. Excluding the impact of non-cash inventory step-up amortization, gross profit as a percentage of revenue would have been 71.5% and 71.2% for the three months ended June 30, 2025 and 2024, respectively.

Biopharmaceutical Development

Our Biopharmaceutical Development division ("BPD") develops, manufactures, sells and services automated systems for protein analysis (immunoassays) and peptide synthesis solutions. Immunoassays and peptide synthesis solutions accelerate the discovery, development and manufacture of biotherapeutic therapies, among other applications.

	Three Months Ended June 30,						Total
amounts in thousands, except percent data		2025			2024		Change
Revenues	$	11,486		$	12,008			(4.3	%)
Gross profit		6,306			7,959			(20.8	%)
Gross profit as a % of revenues		54.9	%		66.3	%	(11.4 pt)

The Biopharmaceutical Development division's revenues decreased 4.3% for the three months ended June 30, 2025 versus the comparable prior year period. The decline in revenues for the three months ended June 30, 2025 was driven by the timing of customer immunoassays order placements, including order delays as customers navigate purchasing decisions amid evolving macroeconomic uncertainty and tariff conditions, partially offset by higher reported revenues from the strengthening of the euro against the U.S. dollar. While revenues from hardware, and to a lesser extent consumables, declined, revenues from services increased 3.5% for the three months ended June 30, 2025 versus the comparable prior year period.

Gross profit as a percentage of revenues for the Biopharmaceutical Development division decreased 11.4 percentage points for the three months ended June 30, 2025. The decrease was primarily due to unfavorable product mix as higher-margin immunoassays revenues comprised approximately 68% of the division’s total revenues, versus approximately 76% in the comparable prior year period, and decreased revenues. Additionally, a large percentage of the division’s cost of goods is denominated in Swedish krona, which appreciated approximately 12% against the U.S. dollar for the three months ended June 30, 2025 versus the comparable prior year period. We do not expect the peptides mix to remain at elevated levels throughout the rest of fiscal year 2026, and as a result, we anticipate gross margin percentage for the Biopharmaceutical Development division will improve.

Calibration Solutions

The Calibration Solutions division develops, manufactures, sells and services quality control products using principles of advanced metrology to enable customers to measure and calibrate critical parameters in applications such as renal care, environmental and process monitoring, gas flow and torque testing.

	Three Months Ended June 30,						Total
amounts in thousands, except percent data		2025			2024		Change
Revenues	$	12,350		$	11,801			4.7	%
Gross profit		7,042			7,242			(2.8	%)
Gross profit as a % of revenues		57.0	%		61.4	%	(4.4 pt)

The Calibration Solutions division's revenues increased 4.7% for the three months ended June 30, 2025 versus the comparable prior year period, primarily due to commercial efforts to renew contracts with larger customers that incentivized utilization of our service offerings, particularly in our renal care product line and, to a lesser extent, price increases.

The Calibration Solutions division's gross profit as a percentage of revenues decreased 4.4 percentage points for the three months ended June 30, 2025 versus the comparable prior year period, primarily due to increased labor costs, as we have hired additional employees to support future growth, and to a lesser extent as a result of increased manufacturing input costs, primarily due to tariffs, and product mix.

Clinical Genomics

The Clinical Genomics division develops, manufactures and sells highly sensitive high-throughput genetic analysis tools and related consumables and services that enable clinical research labs and contract research organizations to perform genomic testing for a broad range of research applications in several therapeutic areas, such as screenings for hereditary diseases, pharmacogenetics, oncology related applications and toxicology research.

	Three Months Ended June 30,						Total
amounts in thousands, except percent data		2025			2024		Change
Revenues	$	10,297		$	11,404			(9.7	%)
Gross profit		5,425			6,490			(16.4	%)
Gross profit as a % of revenues		52.7	%		56.9	%	(4.2 pt)

The Clinical Genomics division's revenues decreased 9.7% for the three months ended June 30, 2025 versus the comparable prior year period, primarily due to lower sales in China as a result of macroeconomic, regulatory and tariff uncertainty. Decreases in China were partially offset by 18.6% increases in revenues in the United States, primarily from consumables, as we execute our new product development and commercial strategy. While we anticipate revenues growth in the U.S. and Europe in the remainder of the fiscal year, we expect revenues from China over the remainder of the fiscal year to continue to decrease compared to the prior year.

Gross profit percentage for the Clinical Genomics division decreased 4.2 percentage points for the three months ended June 30, 2025 versus the comparable prior year period, primarily due to lower revenues on a partially fixed cost base.

Operating Expense

Operating expense increased 7.0% for the three months ended June 30, 2025 versus the comparable prior year period. Reported selling, general and administrative, and research and development expenses increased due to the weakening of the U.S. dollar against the euro and Swedish krona for the three months ended June 30, 2025 compared to the prior year period.

Selling Expense

Selling expense is driven primarily by labor costs, including salaries and commissions; accordingly, it may vary with sales levels.

	Three Months Ended June 30,						Total
amounts in thousands, except percent data		2025			2024		Change
Selling expense	$	10,933		$	10,116			8.1	%
As a percentage of revenues		18.4	%		17.4	%	1.0 pt

Selling expense for the three months ended June 30, 2025 increased 8.1% versus the comparable prior year period. The increase is primarily attributable to investments in additional personnel expenses in an effort to continue to drive higher organic growth.

General and Administrative Expense

Labor costs, amortization of intangible assets, and non-cash stock-based compensation drive the substantial majority of our general and administrative expense.

	Three Months Ended June 30,						Total
amounts in thousands, except percent data		2025			2024		Change
General and administrative expense	$	17,958		$	16,818			6.8	%
As a percentage of revenues		30.2	%		28.9	%	1.3 pt

General and administrative expense increased 6.8%, primarily due to higher personnel costs, including increased non-cash stock-based compensation resulting from an adjustment to performance-based awards to reflect achievement against targets through June 30, 2025. Increases to stock-based compensation expense were partially offset by lower consulting and professional services expenses, as our prior year results included consulting costs related to integrating GKE into our enterprise resource planning system.

Research and Development Expense

Research and development expense is predominantly comprised of labor costs and costs of third-party consultants.

	Three Months Ended June 30,						Total
amounts in thousands, except percent data		2025			2024		Change
Research and development expense	$	4,984		$	4,735			5.3	%
As a percentage of revenues		8.4	%		8.1	%	0.3 pt

Research and development expenses increased slightly for the three months ended June 30, 2025 versus the comparable prior year period, primarily as a result of purchases of supplies to support project-specific research and development activities.

Non-Operating (Income) Expense, Net

	Three Months Ended June 30,						Total
amounts in thousands, except percent data		2025			2024			Change
Interest expense and amortization of debt issuance costs	$	2,198		$	2,842			(22.7	%)
(Gain) on extinguishment of convertible senior notes		-			(2,887	)		N/A
Other (income) expense, net		(6,146	)		1,720			(457.3	%)
Non-operating (income) expense, net	$	(3,948	)	$	1,675			(335.7	%)

During the three months ended June 30, 2025, the U.S. dollar weakened against the euro. As a result, we recognized unrealized foreign currency gains of approximately $6.1 million from an intercompany U.S. dollar-denominated loan issued in fiscal year 2024 to one of our wholly owned, euro-denominated subsidiaries.

We incurred less interest expense during the three months ended June 30, 2025 versus the comparable prior year period primarily due to lower balances outstanding under our revolving line of credit in fiscal 2026, and to a lesser extent due to lower interest rates on our floating rate debt. We expect interest expense to increase in each remaining quarter of fiscal year 2026 compared to the first quarter of 2026 as our convertible notes mature in August 2025 and will be replaced with a borrowings under our revolving line of credit that will bear interest at a higher rate.

The $2.9 million gain on extinguishment of the convertible notes reported in the first quarter of fiscal year 2025 was a result of the settlement of $75.0 million aggregate principal of the notes during that period.

Income Taxes

	Three Months Ended June 30,						Total
amounts in thousands, except percent data		2025			2024		Change
Income tax expense	$	2,270		$	517			339.1	%
Effective tax rate		32.4	%		13.2	%	19.2 pt

Our effective income tax rate was 32.4% for three months ended June 30, 2025 compared to 13.2% for the three months ended June 30, 2024. The change in the effective tax rate for three months ended June 30, 2025 compared to the prior year period is primarily due to prior year valuation allowance adjustments related to our operations in Germany and an increase in German statutory taxes in the current fiscal year. The effective tax rate for the three months ended June 30, 2025 differed from the statutory federal rate of 21% primarily due to the valuation allowances previously established on the U.S. deferred taxes and varying applicable tax rates in foreign jurisdictions.

Our future effective income tax rate depends on various factors, such as changes in tax laws, regulations, accounting principles, or interpretations thereof, and the geographic composition of our pre-tax income. We carefully monitor these factors and adjust our effective income tax rate accordingly.

Net Income

Net income varies with changes in revenues, gross profit, operating expense, and currency exchange rate fluctuations. Net income included $4.6 million, $3.9 million and $1.4 million of non-cash amortization of intangible assets, stock-based compensation expense, and depreciation expense, respectively, and currency gains of $6.2 million for the three months ended June 30, 2025.

Liquidity and Capital Resources

Our sources of liquidity include cash generated from operations, cash and cash equivalents on hand, and cash available from borrowings under our Credit Facility. We believe these sources of cash are sufficient to meet our ongoing operating requirements, scheduled debt service obligations, dividend payments and anticipated capital expenditures.

Historically, our more significant uses of cash have included acquisitions, payments on debt principal and interest obligations, and quarterly dividends paid to shareholders. In April 2025, we released a $9.6 million holdback payment related to the GKE acquisition. This amount was previously withheld from GKE’s purchase price to cover potential post-closing adjustments and indemnification obligations.

Working capital is the amount by which current assets exceed current liabilities. We had negative working capital of $(51.2) million and $(61.3) million as of June 30, 2025 and March 31, 2025, respectively. Our negative working capital balances are primarily due to the classification of the $97.5 million remaining principal on our Notes, due August 15, 2025, as a current liability on our Condensed Consolidated Balance Sheets. We held $21.3 million and $27.3 million in cash and cash equivalents as of June 30, 2025 and March 31, 2025, respectively.

We have an outstanding Revolver that allows us to borrow to up to $125.0 million. During fiscal year 2024, we borrowed a total of $71.0 million under the Revolver to fund the majority of the GKE acquisition and since then we have borrowed against the revolver from time to time to fund general corporate needs. As of June 30, 2025, $14.0 million remained outstanding. Subsequent to June 30, 2025, we repaid an additional $3,000 on the Revolver.

Including the current portion of our Term Loan and the Notes, principal debt payments due within the next twelve months total $101.7 million. We plan to fund the amounts due using a combination of cash on hand, draws against our Revolver, which had $111.0 million available as of June 30, 2025, and cash generated from operating activities until maturity.

Based on applicable interest rates and debt balances outstanding as of June 30, 2025, we expect to incur approximately $12.3 million in cash interest expense over the next twelve months, adjusted for scheduled principal payments and anticipated borrowings under the Credit Facility to settle the Notes.

We routinely evaluate opportunities for strategic acquisitions. Future material acquisitions may require us to obtain additional capital, assume additional third-party debt or incur other long-term obligations. We believe that we have the ability to issue more equity or debt in the future in order to finance our acquisition and investment activities; however, additional equity or debt financing, or other transactions, may not be available on acceptable terms, if at all.

We may from time to time repurchase or take other steps to reduce our debt. These actions may include retirements or refinancing of outstanding debt through tender offers, privately negotiated transactions, or otherwise. The amount of debt that may be retired, if any, could be material. Retirement would be decided at the sole discretion of our Board of Directors and would depend on market conditions, our cash position and other considerations.

Dividends

We have paid regular quarterly dividends since 2003. We paid dividends of $0.16 per share during the three months ended June 30, 2025, as well as each quarter of fiscal year 2025.

In July 2025, we announced that our Board of Directors declared a quarterly cash dividend of $0.16 per share of common stock, payable on September 15, 2025, to shareholders of record at the close of business on August 29, 2025.

Goodwill Impairment Testing

We perform analyses at least quarterly to identify potential impairment indicators and to assess whether it is more likely than not that any of our five goodwill reporting units (Sterilization and Disinfection Control, Immunoassays (BPD), Peptides (BPD), Calibration Solutions, and Clinical Genomics) is impaired. As of June 30, 2025, we concluded that our reporting units are not impaired; however, adverse economic, market or industry-specific conditions (including declines in our market capitalization), adverse or expected adverse changes in the business climate or in our operational performance, adverse changes in legal or regulatory environments, failure to achieve forecasted cash flows, or any combination of these or other such factors could result in future impairment losses in our reporting units in the future.

Page 27

Table of Contents

Our Clinical Genomics and Peptides reporting units remain particularly sensitive to significant changes in assumptions and therefore have a heightened risk of future impairment losses. The valuation of our reporting units for impairment testing purposes relies on significant management judgment and the use of unobservable Level 3 inputs, including discount rates, forecasted results such as earnings before interest, taxes, depreciation and amortization (“EBITDA”), revenue growth rates, operating expense projections, the identification of comparable public entities, and applied market multiples.

We continue to monitor the impact of tariffs imposed in calendar year 2025. Depending on the persistence and magnitude of the tariffs and other factors, it is reasonably possible our Clinical Genomics and Peptides reporting units will incur impairment losses in the future. As of our most recent annual impairment test on January 1, 2025, the estimated fair values of the Clinical Genomics and Peptides reporting units exceeded their carrying values by approximately 40% and 20%, respectively. As of June 30, 2025, the carrying values of goodwill and other intangible assets associated with our Clinical Genomics reporting unit were $17.1 million and $8.9 million, respectively. The carrying values of goodwill and other intangible assets associated with our Peptides reporting unit were $13.7 million and $0.8 million, respectively, as of June 30, 2025.

Cash Flows

Our cash flows from operating, investing and financing activities were as follows (in thousands):

	Three Months Ended June 30,
amounts in thousands		2025			2024
Net cash provided by operating activities	$	1,893		$	10,743
Net cash (used in) investing activities		(1,009	)		(891	)
Net cash (used in) financing activities		(8,427	)		(9,419	)

Cash flows from operating activities provided $1.9 million, for the three months ended June 30, 2025, a decrease of $8.8 million versus the comparable prior year period. The decrease in cash flows from operating activities was primarily a result of:

●		lower gross margins,
●		higher cash payments in the first quarter of fiscal year 2026 to settle accrued bonus and commissions that were accrued at the end of fiscal year 2025; and
●		increased cash spent on inventory as we purchase finished goods and warehouse them in international locations as part of our tariff strategy.

Cash used in investing activities increased modestly for the three months ended June 30, 2025 compared to the prior year period as we invested in property, plant and equipment across several manufacturing sites. Cash used in financing activities resulted in a $8.4 million use of cash for the three months ended June 30, 2025. We borrowed $10.5 million under the Revolver largely to fund a $9.6 million payment of the GKE acquisition-related holdback and for other general corporate needs. We repaid $7.4 million of principal on our debt in the three months ended June 30, 2025, compared to $9.4 million in the prior year period.

Recent Accounting Pronouncements

For a discussion of the new accounting standards impacting the Company, refer to Note 1. “Description of Business and Summary of Significant Accounting Policies” in Item I. Financial Statements (Unaudited).

Contractual Obligations and Other Commercial Commitments

We are party to contractual obligations that involve commitments to remit payments to third parties in the ordinary course of business. On a consolidated basis, as of June 30, 2025, we had contractual obligations for open purchase orders of approximately $14.2 million for routine purchases of supplies and inventory, of which the substantial majority are payable in less than one year.

See "Liquidity and Capital Resources" for information related to future required debt and other payments. For a description of our contractual obligations and other commercial commitments as of March 31, 2025, see our Annual Report on Form 10-K for the fiscal year ended March 31, 2025, filed with the Securities and Exchange Commission on May 28, 2025.

Critical Accounting Estimates

Critical accounting estimates are those that we consider both significant to the preparation of our financial statements and that require complex, subjective, or highly judgmental assessments. These estimates often involve assumptions about inherently uncertain matters and are based on our historical experience, as well as other factors we believe to be appropriate under the circumstances. For example, we incorporate expert input when developing estimates used in the valuation of reporting units for goodwill impairment testing. The accounting estimates that require significant management judgment and are deemed critical to our results of operations or financial position are discussed in our Annual Report on Form 10-K for the fiscal year ended March 31, 2025, in “Critical Accounting Policies and Estimates” in Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations. While we believe our estimates, assumptions and judgements are reasonable, actual results may differ materially from these estimates.

Non-GAAP Measures

In addition to financial measures prepared in accordance with generally accepted accounting principles, we present organic revenues growth, defined as reported revenues growth excluding revenues from recent acquisitions, as a supplemental non-GAAP financial measure. We believe this measure facilitates comparability between current and prior period information and provides insight into Mesa’s short-term and long-term performance and growth trends. We use organic revenues growth internally for forecasting, evaluating operating performance, comparing current and historical revenue results, and informing financial and operating decision-making, including for compensation-setting purposes.

A reconciliation of organic revenues growth to total revenues growth is as follows:

	Total Revenues Growth						Impact of Acquisitions						Organic Revenues Growth (non-GAAP)
	Three Months Ended June 30,
	2025			2024			2025			2024			2025			2024
Sterilization and Disinfection Control		10.7	%		44.1	%		-	%		(39.2	%)		10.7	%		4.9	%
