Page 5 Table of Contents Mesa Laboratories, Inc. Notes to Condensed Consolidated Financial Statements (unaudited) (dollar and share amounts in thousands, unless otherwise specified) 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 the Asia Pacific region, and by independent distributors throughout the world. As of June 30, 2026 , 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 sterility assurance testing and laboratory services, primarily to dental and pharmaceutical customers. ● 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 biologic 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, gas flow, and environmental and process monitoring. ● Clinical Genomics - develops, manufactures and sells highly sensitive high-throughput genetic analysis instruments, consumables and related services that enable clinical research labs and contract research organizations to perform genomic testing across a broad range of applications in several therapeutic areas, including hereditary disease screenings, 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 U.S. GAAP. 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 have made no material changes to the application of significant accounting policies disclosed in our Annual Report on Form 10 -K for the fiscal year ended March 31, 2026 . This report should be read in conjunction with the consolidated financial statements included in that report. 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. Unless otherwise indicated, amounts shown in this report are in thousands. Page 6 Table of Contents Risks and Uncertainties The preparation of financial statements requires the use of estimates and assumptions that affect reported amounts of assets and liabilities at the reporting date and revenue 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, economic uncertainties, 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. Refer to Item 1A. Risk Factors in our Annual Report on Form 10 -K for the fiscal year ended March 31, 2026 . Recent Accounting Pronouncements We have reviewed all recently issued accounting pronouncements and have concluded that, other than as described below, they are not applicable to us or are not expected to have a material impact on our consolidated financial statements. Recently Adopted Accounting Pronouncements In July 2025, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2025 - 05, Financial Instruments — Credit Losses (Topic 326 ): Improvements to the Measurement of Credit Losses for Receivables and Contract Assets . ASU 2025 - 05 introduces a practical expedient that removes the requirement to incorporate macroeconomic forecasts into the estimation of expected credit losses. The guidance is effective for fiscal years beginning after December 15, 2025, including interim periods within those fiscal years. We adopted the ASU effective April 1, 2026 on a prospective basis and elected the practical expedient allowing us to assume conditions as of the balance sheet date will remain unchanged for the remaining life of the asset. This adoption did not have a material impact on our consolidated financial statements, allowance for credit losses or related disclosures. In September 2025, the FASB issued ASU 2025 - 06, Intangibles — Goodwill and Other (Topic 350 ): Internal-Use Software . ASU 2025 - 06 modernizes accounting for costs incurred in the development of internal-use software by eliminating the requirement to evaluate distinct development stages. The guidance is effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years. ASU 2025 - 06 permits prospective, retrospective or modified retrospective adoption. Early adoption is permitted as of the beginning of an entity's annual reporting period. We early adopted the ASU effective April 1, 2026, on a prospective basis. This adoption did not have a material impact on our consolidated financial statements or related disclosures. Recently Issued Accounting Pronouncements In November 2024, the FASB issued ASU 2024 - 03, Expense Disaggregation Disclosures (Subtopic 220 - 40 ): Disaggregation of Income Statement Expenses. ASU 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 intend to adopt ASU 2024 - 03 prospectively, and we expect to disclose additional detail regarding the nature and classification of certain categories of expense 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 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 requiring 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. Revenue from hardware and consumables are recognized upon transfer of control to the customer. Control of hardware and consumables sold in the U.S. and Asia Pacific typically transfers at the point of shipment, whereas control of products sold in Europe more typically occurs upon delivery to the customer site. Page 7 Table of Contents We also offer maintenance, calibration and testing services. Services result in revenue recognized either over time, for example, when we are contractually obligated to perform labor and replace parts on an as-needed basis throughout a specified service period, or at a point in time, upon completion of a specific, discrete service. We disclose revenue consistently with how management evaluates the business, i.e., based on business unit and the nature of goods and services provided. The following tables present disaggregated revenue for the quarters ended June 30, 2026 and 2025, respectively: Three Months Ended June 30, 2026 Sterilization and Disinfection Control Biopharmaceutical Development Calibration Solutions Clinical Genomics Total Consumables $ 21,925 $ 4,303 $ 810 $ 7,739 $ 34,777 Hardware and software 96 4,898 7,681 1,450 14,125 Services 2,484 2,858 4,794 1,100 11,236 Total revenue $ 24,505 $ 12,059 $ 13,285 $ 10,289 $ 60,138 Three Months Ended June 30, 2025 Sterilization and Disinfection Control Biopharmaceutical Development Calibration Solutions Clinical Genomics Total Consumables $ 23,011 $ 3,836 $ 841 $ 8,085 $ 35,773 Hardware and software 89 4,288 6,975 1,217 12,569 Services 2,310 3,362 4,534 995 11,201 Total revenue $ 25,410 $ 11,486 $ 12,350 $ 10,297 $ 59,543 Revenue 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, 2026 2025 United States $ 29,743 $ 27,646 China 5,437 5,429 Other 24,958 26,468 Total revenue $ 60,138 $ 59,543 No foreign country exceeded 10% of total revenue for the quarter ended June 30, 2026 . Contract Liabilities Our contracts have varying payment terms and conditions. Some customers prepay for products and services, resulting in contract liabilities recorded as unearned revenue or within other noncurrent liabilities in our unaudited Condensed Consolidated Balance Sheets. The significant majority of our revenue, related receivables and contract liabilities arise from contracts with original durations of twelve months or less. Contract liabilities are 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, 2026 $ 14,723 Prior year liabilities recognized in revenue during the three months ended June 30, 2026 ( 3,917 ) Contract liabilities added during the three months ended June 30, 2026, net of revenue recognized 3,717 Contract liabilities as of June 30, 2026 $ 14,523 Page 8 Table of Contents Note 3. Fair Value Measurements and Concentrations of Credit Risk 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 of cash and cash equivalents, trade accounts receivable and trade accounts payable approximate fair value and are classified within Level 1 of the fair value hierarchy. The carrying amounts of our term loan and revolving line of credit (together, the "Credit Facility") approximate fair value due to variable interest rate pricing, with the balances bearing interest rates approximating current market rates. There were no nonrecurring fair value adjustments or transfers between the levels of the fair value hierarchy during the quarter ended June 30, 2026 . 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 cash holdings 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, 2026 . Note 4.

Indebtedness Credit Facility Our secured credit agreement matures in April 2029 and 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. Borrowings under our Credit Facility bear interest at a Secured Overnight Financing Rate ("SOFR") rate or a base rate, plus an applicable spread that varies with our total net leverage ratio. The weighted average interest rate on borrowings under the Credit Facility was 5.6 % as of June 30, 2026 and 5.9 % as of March 31, 2026. The financial covenants in the Credit Facility include a maximum total net leverage ratio of 3.5 to 1.0 on each quarterly testing date after March 31, 2026. The Credit Facility also stipulates a minimum fixed charge coverage ratio of 1.25 to 1.0. 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, 2026 , we were in compliance with all covenants under the Credit Facility. Term Loan We are required to make quarterly principal payments on the Term Loan. During the quarter ended June 30, 2026, we made a required payment of $ 1,406 . For fiscal years ending March 31, required future debt payments on the Term Loan are as follows: Fiscal Year Amount Remainder of 2027 $ 4,219 2028 5,625 2029 7,500 2030 48,750 Total principal remaining $ 66,094 Unamortized debt issuance costs related to the Term Loan are reflected as a discount to the debt’s carrying value in our unaudited Condensed Consolidated Balance Sheets and are being amortized to interest expense through maturity. The net carrying amount of the Term Loan was as follows: June 30, 2026 March 31, 2026 Term Loan ( 5.6 % and 5.9 % as of June 30, 2026 and March 31, 2026, respectively) $ 66,094 $ 67,500 Less: debt issuance costs ( 475 ) ( 518 ) Less: current portion ( 5,625 ) ( 5,625 ) Noncurrent portion $ 59,994 $ 61,357 We recognized interest expense on the Term Loan as follows: Three Months Ended June 30, 2026 2025 Interest expense ( 5.6 % and 7.2 % as of June 30, 2026 and 2025, respectively) $ 995 $ 1,292 Amortization of debt issuance costs 43 37 Total interest and amortization of debt issuance costs $ 1,038 $ 1,329 Page 11 Table of Contents Revolver As of June 30, 2026 , the outstanding balance under the Revolver was $ 77,250 , and $ 47,750 was available for borrowing. Subsequent to June 30, 2026 , we repaid an additional $4,000 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. The balance of unamortized customary lender fees related to the Revolver was $ 934 and $ 1,018 as of June 30, 2026 and March 31, 2026, respectively. Convert ible Notes On August 15, 2025, our previously outstanding 1.375 % convertible notes (the "Notes") matured. We settled the aggregate principal balance of $ 97,500 and accrued interest using borrowings under our Revolver and cash on hand. As of June 30, 2025, the Notes had a net carrying value of $ 97,432 . Interest expense recognized in connection with the Notes during the three months ended June 30, 2025 was $ 470 , consisting of coupon interest expense of $ 335 and amortization of debt issuance costs of $ 135 . Note 7. Stock Transactions and Stock-Based Compensation Stock-Based Compensation During the three months ended June 30, 2026 , we issued time-based restricted stock units ("RSUs") and performance-based restricted stock units ("PSUs") pursuant to the Amended and Restated Mesa Laboratories, Inc. 2021 Equity Incentive Plan (the "2021 Equity Plan"), which authorizes the issuance of 1,156 shares of common stock to eligible participants. The following is a summary of RSU and PSU award activity for the three months ended June 30, 2026 : 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 Nonvested as of March 31, 2026 187 $ 93.39 110 $ 126.18 Awards granted (1) 99 100.47 48 105.38 Awards forfeited ( 10 ) 96.36 ( 16 ) 99.56 Awards distributed ( 68 ) 99.50 ( 13 ) 132.29 Nonvested as of June 30, 2026 208 $ 94.66 129 $ 120.81 ( 1 ) Balances for PSUs granted are reflected at target. In the three months ended June 30, 2026, the Compensation Committee of the Board of Directors (the "Compensation Committee") awarded our CEO a sign-on equity award consisting of 35 RSUs. These RSUs vest in equal installments on April 13, 2027, 2028 and 2029. Time-based RSUs vest and settle in shares of our common stock on a one -for- one basis. The significant majority of other RSUs granted to employees during the three months ended June 30, 2026 vest in equal installments on June 13, 2027, June 8, 2028 and June 8, 2029. During the three months ended June 30, 2026 , the Compensation Committee awarded 48 PSUs at target (the "FY27 PSUs") to eligible employees. The FY27 PSUs are subject to market-based performance conditions measured relative to a selected peer index and service conditions. The market performance measurement period and service period are from June 15, 2026 through June 14, 2029, followed by a mandatory two -year holding period. The number of shares that may be earned will range from 0 % to 200 % of the target number of shares, based on Mesa's relative total shareholder return compared to the selected peer group. If defined minimum targets are not met, no shares will vest. As of June 30, 2026 , there were 105 shares subject to outstanding options, with a weighted average exercise price per share of $ 183.18 , an intrinsic value of $ 0 and a remaining contractual life of 1.8 years. Our Compensation Committee has not granted options to any plan participants in the current or prior fiscal year. Page 12 Table of Contents Liability Classified PSUs During the three months ended June 30, 2026, liability-classified PSUs were granted to certain key employees. The awards may vest based on our over-achievement against a challenging threshold for revenue and adjusted operating income targets; the value of shares awarded will range from $ 0 to approximately $ 3,000 , depending on Company performance. The awards represent a fixed monetary value that will be settled in a variable number of shares and are therefore classified as liabilities. As of June 30, 2026, achievement of performance conditions was not considered probable; as such, no compensation expense or corresponding liability has been recognized in our Condensed Consolidated Financial Statements. Performance is measured from April 1, 2026 to March 31, 2027. Any awards earned will vest in June 2027 and be subject to a mandatory one -year holding period. 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, 2026 2025 Net income available for shareholders $ 2,830 $ 4,742 Weighted average outstanding shares of common stock (1) 5,657 5,465 Dilutive effect of unvested stock awards 100 88 Fully diluted shares 5,757 5,553 Basic earnings per share $ 0.50 $ 0.87 Diluted earnings per share $ 0.49 $ 0.85 ( 1 ) Weighted average outstanding shares of common stock includes awards that have not yet vested and are not yet legally outstanding, but for which no vesting criteria other than the passage of time remain. For example, this includes RSUs granted to retirement-eligible employees and certain awards granted to our former CEO that are not subject to continued service requirements but have not yet vested. The following contingently issuable securities were excluded from the calculation of diluted EPS as their inclusion would be anti-dilutive: Three Months Ended June 30, 2026 2025 Assumed conversion of the Notes - 344 Stock awards that were anti-dilutive 136 161 Total stock awards excluded from diluted EPS 136 505 Stock awards are potentially dilutive securities and as such are excluded from the calculation of diluted EPS if their inclusion would be anti-dilutive, or if achievement of performance-based thresholds as of our reporting date would not result in the awards vesting. Note 9 . Income Taxes We reported an income tax provision as follows: Three Months Ended June 30, 2026 2025 Income tax expense $ 1,523 $ 2,270 Effective tax rate 35.0 % 32.4 % Page 13 Table of Contents 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 effective tax rate for the three months ended June 30, 2026 differed from the statutory federal rate of 21 % primarily due to the impact of the valuation allowance on U.S. deferred taxes. Given our current earnings and anticipated future earnings, we believe that there is a reasonable possibility that within the next 12 months, sufficient positive evidence may become available to allow us to reach a conclusion that a significant portion of the valuation allowance will no longer be needed. However, the exact timing and amount of the valuation allowance release are subject to change on the basis of the level of profitability that we are able to achieve. Note 10 . Commitments and Contingencies As of June 30, 2026 , 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. During the three months ended June 30, 2026, we entered into a settlement agreement that resolved previously disclosed litigation involving True Indicating, LLC. Under the terms of the settlement agreement, we paid an insignificant amount to resolve all outstanding matters between the parties, which was recorded in general and administrative expense in our Condensed Consolidated Statements of Income. We have no remaining obligations under the agreement. Note 11 . S egment Information Segment information is prepared on the same basis our chief operating decision maker ("CODM"), our CEO, uses to assess segment performance, allocate resources, 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 regularly reviews segment-level U.S. GAAP revenue and gross profit relative to forecasted and prior period amounts, as well as non-GAAP adjusted operating expense compared to budgeted amounts. Our CODM also regularly reviews non-GAAP organic revenue growth to support strategic planning and resource deployment. The following tables set forth our segment information: Three months ended June 30, 2026 Sterilization and Disinfection Control Biopharmaceutical Development Calibration Solutions Clinical Genomics Total Revenue (a): $ 24,505 $ 12,059 $ 13,285 $ 10,289 $ 60,138 Less Depreciation in cost of revenue 437 78 111 119 745 Amortization in cost of revenue 121 379 - 191 691 Other cost of revenue (b) 6,788 4,020 5,143 3,739 19,690 Total segment cost of revenue 7,346 4,477 5,254 4,049 21,126 Gross Profit (c) $ 17,159 $ 7,582 $ 8,031 $ 6,240 $ 39,012 Reconciling items: Operating expense $ 31,981 Operating income 7,031 Non-operating expense, net 2,678 Earnings before income taxes $ 4,353 Page 14 Table of Contents Three months ended June 30, 2025 Sterilization and Disinfection Control Biopharmaceutical Development Calibration Solutions Clinical Genomics Total Revenue (a): $ 25,410 $ 11,486 $ 12,350 $ 10,297 $ 59,543 Less Depreciation in cost of revenue 450 89 105 166 810 Amortization in cost of revenue 139 372 - 191 702 Other cost of revenue (b) 6,655 4,719 5,203 4,515 21,092 Total segment cost of revenue 7,244 5,180 5,308 4,872 22,604 Gross Profit (c) $ 18,166 $ 6,306 $ 7,042 $ 5,425 $ 36,939 Reconciling items: Operating expense $ 33,875 Operating income 3,064 Non-operating expense, net ( 3,948 ) Earnings before income taxes $ 7,012 (a) Intersegment revenue are eliminated to arrive at consolidated totals.

Overview 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 the Asia Pacific region, and by independent distributors throughout the world. As of June 30, 2026, we managed our operations in four reportable segments, or divisions: Sterilization and Disinfection Control, Biopharmaceutical Development ("BPD"), Calibration Solutions, and Clinical Genomics. Each of our divisions is described further in "Results of Operations" below. 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 every day by taking a customer-focused approach to developing, building and delivering our products and services. We serve a broad set of industries, particularly 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. Page 16 Table of Contents Our continued growth will depend on our ability to (i) expand business with new and existing customers through ongoing commercial efforts, including in new geographic areas, (ii) manage our costs and allocate resources to ensure continued profitability, (iii) identify, consummate and integrate acquisitions successfully, and (iv) 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. Organic Revenue Growth Organic revenue 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 exchange rates on our reported revenue. Our ability to increase organic revenue is affected by general domestic and global economic conditions, customer capital spending trends, currency exchange rates, competition, 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 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. We are actively pursuing opportunities to expand our customer base both domestically and internationally by fostering strong relationships with existing and new customers and distributors. Inorganic Growth - Acquisitions Over the past decade, we have consummated a number of acquisitions of businesses, technologies, and intangible assets 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 a growth mindset. We continue to promote a culture that values learning, continuous improvement and accountability. We believe this culture strengthens our execution so that we can enhance customer outcomes and create long-term stakeholder value. Our gross profit is affected by many factors, including the mix of products and services sold and the geographical regions in which we sell them, labor and product costs (including costs of transporting, importing and exporting goods, as well as associated tariffs), manufacturing efficiencies, foreign currency rates and price competition. Gross profit percentages differ among product lines, and ultimately our mix of revenue will impact our overall gross profit. We continuously pursue opportunities to improve the efficiency of our administrative functions, including through increasing usage of process automation and artificial intelligence. Hire, Develop, and Retain Top Talent At the center of our organization are skilled people who are capable of taking on new challenges using a team-based approach. Indeed, it is our exceptional workforce that collaborates to continuously and sustainably improve our products, our services, and ourselves, resulting in long-term value creation for our stakeholders. General Trends Revenue increased 1.0% during the three months ended June 30, 2026 compared to the prior year period, driven by growth in the Calibration Solutions and Biopharmaceutical Development divisions, partially offset by lower revenue in the Sterilization and Disinfection Control division. Revenue in the Clinical Genomics division were essentially flat, as growth outside China offset continued weakness in that market. While revenue in China continued to decrease, the year-over-year reduction was significantly smaller than in the prior-year period following substantial revenue declines in recent fiscal years. Gross profit as a percentage of revenue increased 2.9 percentage points compared with the prior year period. The improvement over the comparable prior year period was primarily driven by lower spend on third-party contracted labor and consultants, supply chain efficiency improvements, and favorable product mix, particularly in the Biopharmaceutical Development and Clinical Genomics divisions. Operating expenses decreased 5.6% compared with the prior year period, primarily due to lower stock-based compensation expense. Excluding stock-based compensation expense, operating expenses decreased 1.5% compared with the prior year period and were consistent as a percentage of revenue. Page 17 Table of Contents For the three months ended June 30, 2026, revenue grew 1.0% and operating income increased approximately $4.0 million reflecting operating efficiencies and cost-containment initiatives implemented during the second quarter of fiscal year 2026. We generated $14.7 million of operating cash flows in the three months ended June 30, 2026, which enabled us to reduce outstanding debt by $8.7 million. Results of Operations Our results of operations and period-over-period changes are discussed in the following section. The tables and discussion below should be read in conjunction with the accompanying unaudited Condensed Consolidated Financial Statements and the notes thereto appearing in Item 1. Financial Statements . Results by reportable segment are as follows: Revenue Revenue Growth Gross Profit as a % of Revenue Three Months Ended June 30, amounts in thousands, except percent data 2026 2025 2026 2025 2026 2025 Sterilization and Disinfection Control $ 24,505 $ 25,410 (3.6 %) 10.7 % 70.0 % 71.5 % Biopharmaceutical Development 12,059 11,486 5.0 % (4.3 %) 62.9 % 54.9 % Calibration Solutions 13,285 12,350 7.6 % 4.7 % 60.5 % 57.0 % Clinical Genomics 10,289 10,297 (0.1 %) (9.7 %) 60.6 % 52.7 % Total $ 60,138 $ 59,543 1.0 % 2.4 % 64.9 % 62.0 % Our unaudited condensed consolidated results of operations are as follows: Three Months Ended June 30, amounts in thousands, except percent data 2026 2025 Total Change Revenue $ 60,138 $ 59,543 1.0 % Cost of revenue 21,126 22,604 (6.5 %) Gross profit 39,012 36,939 5.6 % Operating expense 31,981 33,875 (5.6 %) Operating income 7,031 3,064 129.5 % Net income $ 2,830 $ 4,742 (40.3 %) Reportable Segments Sterilization and Disinfection Control Our Sterilization and Disinfection Control division 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 sterility assurance testing and laboratory services, primarily to dental and pharmaceutical customers. Sterilization and Disinfection Control products are disposable and are used on a routine basis. Three Months Ended June 30, amounts in thousands, except percent data 2026 2025 Total Change Revenue $ 24,505 $ 25,410 (3.6 %) Gross profit 17,159 18,166 (5.5 %) Gross profit as a % of revenue 70.0 % 71.5 % (1.5 pt) Revenue for the Sterilization and Disinfection Control division decreased 3.6% for the three months ended June 30, 2026 compared with the prior year period. The decrease was primarily attributable to fulfillment and delivery execution challenges that impacted the timing of customer shipments during the three months ended June 30, 2026. Page 18 Table of Contents Gross profit as a percentage of revenue decreased for the three months ended June 30, 2026 versus the prior year period, primarily as a result of lower revenue on a partially fixed cost base and product mix, partially offset by a decrease in professional services expenses, as we engaged outside expertise in the prior year to improve our production processes. Biopharmaceutical Development Our Biopharmaceutical Development division 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 biologic therapies, among other applications. Three Months Ended June 30, amounts in thousands, except percent data 2026 2025 Total Change Revenue $ 12,059 $ 11,486 5.0 % Gross profit 7,582 6,306 20.2 % Gross profit as a % of revenue 62.9 % 54.9 % 8.0 pt Revenue for the Biopharmaceutical Development division increased 5.0% for the three months ended June 30, 2026 compared with the prior year period, primarily driven by higher immunoassays hardware and consumables sales volumes, and to a lesser extent, price increases. Sales volumes in the prior year period were negatively impacted by order delays as customers deferred purchasing decisions amid rapidly evolving tariff conditions and macroeconomic uncertainty. Gross profit as a percentage of revenue for the Biopharmaceutical Development division increased 8.0 percentage points for the three months ended June 30, 2026 versus the comparable prior year period. The increase was primarily due to favorable product mix, as higher-margin immunoassays revenue represented a greater proportion of the division's total revenue and lower margin instruments represented a smaller portion of total peptides systems revenue. Efficiencies in our supply chain management and higher revenue on a partially fixed cost base also contributed to the increase. 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, gas flow, and environmental and process monitoring. Three Months Ended June 30, amounts in thousands, except percent data 2026 2025 Total Change Revenue $ 13,285 $ 12,350 7.6 % Gross profit 8,031 7,042 14.0 % Gross profit as a % of revenue 60.5 % 57.0 % 3.5 pt Revenue for the Calibration Solutions division increased 7.6% for the three months ended June 30, 2026 versus the comparable prior year period, primarily due to increased sales volumes across several product lines and the impact of price increases. Gross profit as a percentage of revenue increased 3.5 percentage points for the three months ended June 30, 2026 versus the comparable prior year period, primarily due to higher revenue on a partially fixed cost base partially offset by unfavorable product mix. Clinical Genomics The Clinical Genomics division develops, manufactures and sells highly sensitive high-throughput genetic analysis instruments, consumables and related services that enable clinical research labs and contract research organizations to perform genomic testing across a broad range of applications in several therapeutic areas, including hereditary disease screenings, pharmacogenetics, oncology related applications and toxicology research. Three Months Ended June 30, amounts in thousands, except percent data 2026 2025 Total Change Revenue $ 10,289 $ 10,297 (0.1 %) Gross profit 6,240 5,425 15.0 % Gross profit as a % of revenue 60.6 % 52.7 % 7.9 pt Revenue in the Clinical Genomics division were essentially flat, as modest growth outside China offset continued weakness in that market. While revenue in China continued to decrease, the year-over-year reduction was significantly smaller than in the prior-year period following substantial revenue declines in recent fiscal years. Page 19 Table of Contents Clinical Genomics’ gross profit as a percentage of revenue increased 7.9 percentage points for the three months ended June 30, 2026 versus the prior year period. The increase in gross profit as a percentage of revenue was primarily attributable to price increases and manufacturing and supply chain efficiency improvements. Operating Expense Operating expense decreased 5.6% for the three months ended June 30, 2026 versus the comparable prior year period. Operating expense as a percentage of revenue decreased 3.7 percentage points for the three months ended June 30, 2026 versus 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, amounts in thousands, except percent data 2026 2025 Total Change Selling expense $ 9,872 $ 10,933 (9.7 %) As a percentage of revenue 16.4 % 18.4 % (2.0 pt) Selling expense decreased 9.7% for the three months ended June 30, 2026 versus the prior year period, primarily due to lower personnel costs, and to a lesser extent, lower professional services as we continue to realize the benefits of previously announced cost-reduction initiatives. 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, amounts in thousands, except percent data 2026 2025 Total Change General and administrative expense $ 17,384 $ 17,958 (3.2 %) As a percentage of revenue 28.9 % 30.2 % (1.3 pt) General and administrative expense decreased 3.2% for the three months ended June 30, 2026 compared with the prior year period, primarily as a result of lower stock-based compensation expense, as the prior year period included expense related to certain multi-year equity awards granted to our former CEO. The decrease was partially offset by higher personnel costs attributable to inflation and costs incurred to settle a litigation matter. 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, amounts in thousands, except percent data 2026 2025 Total Change Research and development expense $ 4,725 $ 4,984 (5.2 %) As a percentage of revenue 7.9 % 8.4 % (0.5 pt) Research and development expense decreased 5.2% for the three months ended June 30, 2026 compared to the prior year period, primarily due to lower personnel costs resulting from cost-saving initiatives implemented during the second quarter of the prior fiscal year. Non-Operating Expense (Income), Net Three Months Ended June 30, amounts in thousands, except percent data 2026 2025 Total Change Interest expense and amortization of debt issuance costs $ 2,363 $ 2,198 7.5 % Other expense (income), net 315 (6,146 ) (105.1 %) Total non-operating expense (income), net $ 2,678 $ (3,948 ) (167.8 %) Page 20 Table of Contents Interest expense increased for the three months ended June 30, 2026 compared to the prior year period, primarily reflecting the replacement of the Notes with borrowings under our Credit Facility, which carries a higher interest rate. The increase was partially offset by lower weighted‑average levels of outstanding interest‑bearing debt. We repaid the Notes using $97.0 million of borrowings under the Credit Facility’s Revolver in the second quarter of fiscal year 2026. Other expense (income), net primarily consists of gains and losses on foreign currency transactions. During the prior year period, the U.S. dollar weakened significantly against the euro, resulting in 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. Income Taxes Three Months Ended June 30, amounts in thousands, except percent data 2026 2025 Total Change Income tax expense $ 1,523 $ 2,270 (32.9 %) Effective tax rate 35.0 % 32.4 % 2.6 pt Our effective income tax rate was 35.0% and 32.4%, respectively, for the three months ended June 30, 2026 and 2025. The effective tax rate for the three months ended June 30, 2026 and 2025 differed from the statutory federal rate of 21% primarily due to the impact of the valuation allowance on U.S. deferred taxes. Our future effective income tax rate depends on various factors, such as changes in the realizability of deferred tax assets, 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. We currently expect a reasonable possibility of a favorable impact on our effective tax rate within the next 12 months from a potential partial release of the U.S. valuation allowance, although the timing and amount remain subject to our ongoing assessment and other factors affecting the tax rate. Net Income Net income varies with changes in revenue, gross profit, operating expense, and currency exchange rate fluctuations. Net income included $4.4 million, $2.4 million and $1.3 million of non-cash amortization of intangible assets, stock-based compensation expense, and depreciation expense, respectively, for the three months ended June 30, 2026. Liquidity and Capital Resources Our sources of liquidity include cash generated from operations, cash on hand, and cash available from borrowings under our Credit Facility. We believe these sources of cash are sufficient to meet our ongoing operating needs, scheduled debt service obligations, dividend payments and anticipated capital expenditures. As of June 30, 2026 and March 31, 2026, we held $30.7 million and $26.9 million of cash, respectively. Historically, our more significant uses of cash have included acquisitions, payments on debt principal and interest obligations, and quarterly dividends paid to shareholders. Working capital, defined as the amount by which current assets exceed current liabilities, was $45.5 million as of June 30, 2026, compared to working capital of $44.4 million as of March 31, 2026. The Revolver provides borrowing capacity of up to $125.0 million, of which $77.3 million was outstanding as of June 30, 2026. Subsequent to June 30, 2026, we repaid an additional $4.0 million of outstanding Revolver borrowings. Based on debt outstanding and interest rates in effect as of June 30, 2026, we expect to incur approximately $7.9 million of cash interest expense over the next twelve months. Required principal debt payments due on our Term Loan within the next twelve months total $5.6 million. We believe that we have the ability to issue more equity or debt in the future in order to finance our investment activities; however, additional equity or debt financing, or other transactions, may not be available on acceptable terms, if at all. Dividends We have paid regular quarterly dividends since 2003. We paid dividends of $0.16 per share during the three months ended June 30, 2026 and 2025. In July 2026, we announced that our Board of Directors declared a quarterly cash dividend of $0.16 per share of common stock, payable on September 15, 2026, to shareholders of record at the close of business on August 31, 2026. Page 21 Table of Contents Goodwill Impairment Testing We perform qualitative analyses at least quarterly to identify potential indicators of impairment 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, 2026, we concluded that there were no indicators of impairment for any of our reporting units. Cash Flows Our cash flows from operating, investing and financing activities were as follows: Three Months Ended June 30, amounts in thousands 2026 2025 Net cash provided by operating activities $ 14,736 $ 1,893 Net cash (used in) investing activities (559 ) (1,009 ) Net cash (used in) financing activities (10,498 ) (8,427 ) Cash flows from operating activities provided $14.7 million for the three months ended June 30, 2026, an increase of $12.8 million versus the prior year period. The increase was primarily driven by a $6.3 million increase in collections from customers across several of our businesses as well as improved operating performance, including a $4.0 million increase in operating income. Cash used in investing activities decreased for the three months ended June 30, 2026 versus the prior year period as we invested in property, plant and equipment for our new leased facility in Sweden in the prior year. Cash used in financing activities resulted in a $10.5 million use of cash for the three months ended June 30, 2026, including: ● Repayment of net $7.3 million in principal under the Revolver ● Repayment of $1.4 million in principal under the Term Loan Higher debt repayments compared to the prior year period were supported by increased cash generated from operations. 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 1. 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, 2026, we had contractual obligations for open purchase orders of approximately $12.5 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, 2026, see our Annual Report on Form 10-K for the fiscal year ended March 31, 2026. 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. 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, 2026 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. Page 22 Table of Contents I tem 3.
