"IDEXX made exceptional progress on our innovation-driven growth strategy with strong execution and global customer adoption," said Jay Mazelsky, President and Chief Executive Officer. "Building on the successful launch of IDEXX Cancer Dx<sup>™</sup>, new Catalyst specialty tests for Pancreatic Lipase and Cortisol, and the transformative impact of IDEXX inVue Dx, we are delivering powerful new diagnostic capabilities. These solutions elevate clinical insights, streamline workflows, and create meaningful value for veterinary teams. The enthusiastic response — as reflected in our strong growth profile —highlights the trust our customers place in IDEXX."

**Third Quarter Performance Highlights**

**Companion Animal Group ("CAG")**

CAG revenue growth was led by CAG Diagnostics recurring revenue growth of 11% as reported and 10% organic, including 18% reported and 14% organic gains in International regions, and 8% reported and organic growth in the U.S., outpacing sector growth levels. U.S. growth was aided by increased diagnostic frequency and an easing of clinical visit pressures.

Additional U.S. companion animal practice key metrics are available in the *Q3 2025 Earnings Snapshot* accessible on the IDEXX website, <u>www.idexx.com/investors</u>.

Sustained commercial execution - including net customer gains, growing benefits from IDEXX innovation, and expansion of the premium instrument installed base - drove double-digit CAG Diagnostics recurring revenue growth.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **IDEXX VetLab™ consumables** generated 18% reported and 16% organic revenue growth, supported by testing utilization gains,
including increasing benefit from recent product launches, and 10% growth in IDEXX's global premium instrument installed base.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Reference laboratory diagnostic and consulting services** generated 10% reported and 9% organic revenue growth, with benefits
from higher testing volumes, net new customer gains, and net price benefits.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Rapid assay products** revenues declined 4% as reported and 5% on an organic basis, with volumes continuing to be impacted from
the late prior year launch of the Catalyst™ Pancreatic Lipase Test, which shifted some testing across modalities, offsetting net
price benefits.

CAG Diagnostics capital instrument revenues expanded 74% as reported and 71% on an organic basis, led by very strong quarterly instrument placements, including benefits from over 1,700 IDEXX inVue Dx placements.

Veterinary software, services and diagnostic imaging systems revenues grew 11% on a reported and organic basis for the quarter, led by cloud-native software growth and continued installed base expansion.

**Water**

Water revenues grew 8% as reported and 7% organic for the quarter, reflecting solid organic growth both in the U.S. and Internationally.

**Livestock, Poultry and Dairy ("LPD")**

LPD revenues increased 17% as reported and 14% organic for the quarter, led by strong growth across core product categories and major geographies.

**Gross Profit and Operating Profit**

Gross profits increased 15% as reported and 13% on a comparable basis. Gross margin of 61.8% increased 70 basis points as reported and 80 basis points on a comparable basis, supported by Reference Labs productivity initiatives and volume gains, strong growth of IDEXX VetLab consumables revenue, and benefits from net price realization helping to offset inflationary impacts.

Operating margin was 32.1% for the quarter, higher than the prior year period by 100 basis points as reported and by 120 basis points on a comparable basis. Operating margin results reflect a 12% operating expense increase as reported and 10% growth on a comparable basis. Operating expense growth was driven by investments in commercial resources, higher R&D spend related to advancing the Company's innovation agenda, and higher employee benefit and incentive costs.

**2025** **Growth and Financial Performance Outlook**

The Company is updating its full year revenue growth guidance range to $4,270 million - $4,300 million, or reported growth of 9.6% - 10.3%, an increase of $43 million at midpoint. This reflects a positive adjustment of ~1% at midpoint to full year estimates for reported revenue growth, reflecting strong CAG Diagnostics recurring revenue performance and outlook for higher IDEXX inVue Dx instrument placements and revenues. The Company is increasing its outlook for organic revenue growth to 8.8% - 9.5%, an increase of ~1% at midpoint, reflecting the operational performance benefits highlighted above.

The Company increased its full year reported operating margin outlook to 31.6% - 31.8%, bringing the projected full year operating profit margin expansion to 260 - 280 basis points as reported and 80 - 100 basis points on a comparable basis. This outlook benefits from strong third quarter operating performance, while advancing strategic investment priorities.

The Company updated its EPS outlook range to $12.81 - $13.01, incorporating a $0.33 increase at midpoint versus prior guidance, reflecting $0.22 benefit from operational performance, $0.04 benefit from lower effective tax rate, net of impacts related to recent U.S. tax law changes, and ~$0.07 combined benefit from updated estimates for interest expense, average shares outstanding, and foreign exchange impacts. The updated EPS growth outlook is 20% - 22% as reported and 12% - 14% on a comparable basis.

These statements are intended to provide management's expectations or forecasts of future events as of the date of this earnings release; are based on management's estimates, projections, beliefs, and assumptions as of the date of this earnings release; and are not guarantees of future performance. These forward-looking statements involve known and unknown risks and uncertainties that may cause the Company's actual results, levels of activity, performance or achievements to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, among other things, the matters described under the headings "Business," "Risk Factors," "Legal Proceedings," "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Quantitative and Qualitative Disclosures About Market Risk" in the Company's Annual Report on Form 10-K for the year ended December 31, 2024 and in the corresponding sections of the Company's Quarterly Reports on Form 10-Q for the quarters ended March 31, 2025, June 30, 2025, and September 30, 2025, as well as those described from time to time in the Company's other filings with the U.S. Securities and Exchange Commission available at www.sec.gov. The Company specifically disclaims any obligation to publicly update any forward-looking statement, whether as a result of new information, future events or otherwise.*

**Statement Regarding Non-GAAP Financial Measures**

*The following defines terms and conventions and provides reconciliations regarding certain measures used in this earnings release and/or the accompanying earnings conference call that are not required by, or presented in accordance with, generally accepted accounting principles in the United States of America ("GAAP"), otherwise referred to as non-GAAP financial measures. To supplement the Company's consolidated results presented in accordance with GAAP, the Company has disclosed non-GAAP financial measures that exclude or adjust certain items. Management believes these non-GAAP financial measures provide useful supplemental information for its and investors' evaluation of the Company's business performance and liquidity and are useful for period-over-period comparisons of the performance of the Company's business and its liquidity and to the performance and liquidity of our peers. While management believes that these non-GAAP financial measures are useful in evaluating the Company's business, this information should be considered as supplemental in nature and should not be considered in isolation or as a substitute for the related financial information prepared in accordance with GAAP. In addition, these non-GAAP financial measures may not be the same as similarly titled measures reported by other companies.*

<u>Constant currency</u> - Constant currency references are non-GAAP financial measures which exclude the impact of changes in foreign currency exchange rates and are consistent with how management evaluates our performance and comparisons with prior and future periods. We estimate the net impacts of currency on our revenue, gross profit, operating profit, and EPS results by restating results to the average exchange rates or exchange rate assumptions for the comparative period, which includes adjusting for the estimated impacts of foreign currency hedging transactions and certain impacts on our effective tax rates. These estimated currency changes impacted third quarter 2025 results as follows: increased gross profit growth by 1.3%, decreased gross margin expansion by 10 basis points, increased operating expense growth by 2.0%, increased operating profit growth by 0.6%, decreased operating profit margin growth by 20 basis points, and increased EPS growth by 0.3%. Constant currency revenue growth represents the percentage change in revenue during the applicable period, as compared to the prior year period, excluding the impact of changes in foreign currency exchange rates. See the supplementary analysis of results below for revenue percentage change from currency for the three and nine months ended September 30, 2025 and refer to the 2025 Growth and Financial Performance Outlook section of this earnings release for estimated foreign currency exchange rate impacts on 2025 projections and estimates.

<u>Growth and organic revenue growth</u> - All references to growth and organic growth refer to growth compared to the equivalent prior year period unless specifically noted. Organic revenue growth is a non-GAAP financial measure that represents the percent change in revenue, as compared to the same period for the prior year, net of the impact of changes in foreign currency exchange rates, certain business acquisitions, and divestitures. Management believes that reporting organic revenue growth provides useful information to investors by facilitating easier comparisons of our revenue performance with prior and future periods and to the performance of our peers. Organic revenue growth should be considered in addition to, and not as a replacement of or a superior measure to, revenue growth reported in accordance with GAAP. See the supplementary analysis of results below for a reconciliation of reported revenue growth to organic revenue growth for the three and nine months ended September 30, 2025. Please refer to the constant currency note above for a summary of foreign currency exchange rate impacts. Please refer to the 2025 Growth and Financial Performance Outlook section of this earnings release for estimated full year 2025 organic revenue growth for the Company and CAG Diagnostics recurring revenue growth. The percentage change in revenue resulting from acquisitions represents revenues during the current year period, limited to the initial 12 months from the date of the acquisition, that are directly attributable to business acquisitions. Revenue from acquisitions is expected to have an immaterial impact on projected full year 2025 revenue growth and no impact on CAG Diagnostics recurring revenue growth.

<u>Comparable growth metrics</u> - Comparable gross profit growth, comparable gross margin gain (or growth), comparable operating expense growth, comparable operating profit growth and comparable operating margin gain (or growth) are non-GAAP financial measures and exclude the impact of changes in foreign currency exchange rates and non-recurring or unusual items (if any). Please refer to the constant currency note above for a summary of foreign currency exchange rate impacts. Management believes that reporting comparable gross profit growth, comparable gross margin gain (or growth), comparable operating expense growth, comparable operating profit growth and comparable operating margin gain (or growth) provides useful information to investors because it enables better period-over-period comparisons of the fundamental financial results by excluding items that vary independent of performance and provides greater transparency to investors regarding key metrics used by management. Comparable gross profit growth, comparable gross margin gain (or growth), comparable operating expense growth, comparable operating profit growth and comparable operating margin gain (or growth) should be considered in addition to, and not as replacements of or superior measures to, gross profit growth, gross margin gain, operating expense growth, operating profit growth and operating margin gain reported in accordance with GAAP.

The reconciliation of these non-GAAP financial measures is as follows:

Projected 2025 comparable operating margin expansion outlined in the 2025 Growth and Financial Performance Outlook section of this earnings release reflects the following adjustments: (i) adjustment to projected 2025 operating margin for an immaterial impact from year-over-year foreign currency exchange rate changes at noted exchange rates; and (ii) adjustment to projected 2025 operating margin for positive impact of the approximately $9 million discrete litigation expense accrual adjustment in the first quarter of 2025; and (iii) adjustment to full year 2024 reported operating margin for the negative impact of the $61.5 million discrete litigation expense accrual adjustment in the second quarter of 2024.

These impacts described above reconcile reported gross profit growth, gross margin gain, operating expense growth, operating profit growth and operating margin gain (including projected 2025 operating margin expansion) to comparable gross profit growth, comparable gross margin gain, comparable operating expense growth, comparable operating profit growth and comparable operating margin gain for the Company.

<u>Comparable EPS growth</u> - Comparable EPS growth is a non-GAAP financial measure that represents the percentage change in earnings per share (diluted) ("EPS") for a measurement period, as compared to the prior base period, net of the impact of changes in foreign currency exchange rates from the prior base period and excluding the tax benefits of share-based compensation activity under ASU 2016-09, *Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting*, and non-recurring or unusual items (if any). Management believes comparable EPS growth is a more useful way to measure the Company's business performance than EPS growth because it enables better period-over-period comparisons of the fundamental financial results by excluding items that vary independent of performance and provides greater transparency to investors regarding a key metric used by management. Comparable EPS growth should be considered in addition to, and not as a replacement of or a superior measure to, EPS growth reported in accordance with GAAP. Please refer to the constant currency note above for a summary of foreign currency exchange rate impacts.

The reconciliation of this non-GAAP financial measure is as follows:

Projected 2025 comparable EPS growth outlined in the 2025 Growth and Financial Performance Outlook section of this earnings release reflects the following adjustments: (i) adjustment to projected full year 2025 reported EPS for estimated positive share-based compensation activity of ~$0.28; and (ii) adjustment to projected full year 2025 reported EPS for estimated positive year-over-year foreign currency exchange rate change impact of ~$0.11 at noted exchange rates; (iii) adjustment to projected full year 2025 reported EPS for a positive $0.08 impact from the discrete litigation expense accrual adjustment in the first quarter of 2025; (iv) adjustment to full year 2024 reported EPS for a negative $0.56 impact from the discrete litigation expense accrual adjustment in the second quarter of 2024; and (v) adjustment to full year 2024 reported EPS for positive impact of share-based compensation activity of $0.24.

These impacts and those described in the constant currency note above reconcile reported EPS growth (including projected 2025 reported EPS growth) to comparable EPS growth for the Company.

<u>Segment and Other Income from Operations</u> - We report segment income from operations in our Segment Information table below. Segment income from operations is a non-GAAP financial measure that adjusts for the impact of foreign currency transaction gains and losses and should be considered in addition to, and not as a replacement for, or superior measure to, income from operations. We exclude foreign currency transaction gains and losses for each reportable segment (CAG, Water, and LPD) from segment income from operations and report the full amount of foreign currency transaction gains and losses in Other. We believe that reporting segment income from operations provides supplemental analysis to help investors further evaluate each reportable segment's business performance by excluding foreign currency transaction gains and losses, which are centrally managed by our corporate treasury function and which we do not consider relevant for assessing the results of each reportable segment's operations. In addition, we believe that reporting segment income from operations provides information to investors regarding key metrics that are used by management, including our chief operating decision-maker, in evaluating the performance of each reportable segment.

<u>Free cash flow</u> - Free cash flow is a non-GAAP financial measure and means, with respect to a measurement period, the cash generated from operations during that period, reduced by the Company's investments in property and equipment. Management believes free cash flow is a useful measure because it indicates the cash the operations of the business are generating after appropriate reinvestment for recurring investments in property and equipment that are required to operate the business. Free cash flow should be considered in addition to, and not as a replacement of or a superior measure to, net cash provided by operating activities. See the supplementary analysis of results below for our calculation of free cash flow for the three and nine months ended September 30, 2025 and 2024. To estimate projected 2025 free cash flow, we have deducted projected purchases of property and equipment (also referred to as capital expenditures) of approximately $140 million. Free cash flow conversion, or the net income to free cash flow ratio, is a non-GAAP financial measure that is defined as free cash flow, with respect to a measurement period, divided by net income for the same period. To calculate trailing twelve-month net income to free cash flow ratio for the twelve months ended September 30, 2025, we have deducted purchases of property and equipment of approximately $124 million from net cash provided from operating activities of approximately $1,088 million, divided by net income of approximately $1,027 million.

<u>Debt to Adjusted EBITDA (Leverage Ratios</u>) - Adjusted EBITDA, gross debt, and net debt are non-GAAP financial measures. Adjusted EBITDA is a non-GAAP financial measure of earnings before interest, taxes, depreciation, amortization, non-recurring transaction expenses incurred in connection with acquisitions, share-based compensation expense, and certain other non-cash losses and charges. Management believes that reporting Adjusted EBITDA, gross debt, and net debt in the Debt to Adjusted EBITDA ratios provides supplemental analysis to help investors further evaluate the Company's business performance and available borrowing capacity under the Company's credit facility. Adjusted EBITDA, gross debt, and net debt should be considered in addition to, and not as replacements of or superior measures to, net income or total debt reported in accordance with GAAP. For further information on how Adjusted EBITDA and the Debt to Adjusted EBITDA Ratios are calculated, see the Company's Annual Report on Form 10-K for the year ended December 31, 2024 and Quarterly Report on Form 10-Q for the quarter ended September 30, 2025.

**Notes and Definitions**

<u>Discrete litigation expense accrual</u> - During the second quarter of 2024, the Company increased its previously established $27.5 million accrual related to a now-concluded litigation matter by $61.5 million. During the first quarter of 2025, the Company reduced this previously established $89.0 million accrual by approximately $9 million, resulting in a total accrual for this now-concluded litigation matter of approximately $80 million as of March 31, 2025, which represented our best estimate at that time of the amount of the loss.

<u>Now-concluded litigation matter</u> - The Company was a defendant in a litigation matter involving an alleged breach of contract for underpayment of royalty payments made from 2004 through 2017 under an expired patent license agreement, and the trial court ruled in favor of the plaintiff in 2020. Following appeals and in light of the appellate court's April 3, 2025 decision, on April 17, 2025, the Company paid the judgment of approximately $80 million, and the plaintiff executed a satisfaction and release of judgment, which was filed with the trial court on the same date, concluding this matter. For further information, see the Company's Quarterly Report on Form 10-Q for the quarter ended September 30, 2025.
