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.

IDEXX Announces Third Quarter Results November 2, 2026 Page 7 of 17 Constant currency - 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 2026 results as follows: increased gross profit growth by 0.2%, increased gross margin expansion 20 basis points, decreased operating expense growth by 0.9%, increased operating profit growth by 1.2%, increased operating profit margin growth by 40 basis points, and increased EPS growth by 1.2%. 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, 2026 and refer to the 2026 Growth and Financial Performance Outlook section of this earnings release for estimated foreign currency exchange rate impacts on 2026 projections and estimates. Growth and organic revenue growth - 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 percentage change in revenue, as compared to the same period for the prior year, net of the effect 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, 2026. Please refer to the constant currency note above for a summary of foreign currency exchange rate impacts. Please refer to the 2026 Growth and Financial Performance Outlook section of this earnings release for estimated full year 2026 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 2026 revenue growth and no impact on CAG Diagnostics recurring revenue growth. We exclude from organic revenue growth the effect of changes in foreign currency exchange rates because changes in foreign currency exchange rates are not under management’s control, are subject to volatility, and can obscure underlying business trends. We calculate the impact on revenue resulting from changes in foreign currency exchange rates by applying the difference between the weighted average exchange rates during the current period and the comparable prior year period to foreign currency denominated revenues for the prior year period. We also exclude from organic revenue growth the effect of certain business acquisitions and divestitures because the nature, size, and number of these transactions can vary dramatically from period to period, and because they either require or generate cash as an inherent consequence of the transaction, and therefore can also obscure underlying business and operating trends. We consider acquisitions to be a business when all three elements of inputs, processes, and outputs are present, consistent with ASU 2017-01, “Business Combinations: (Topic 805) Clarifying the Definition of a Business.” We do not consider acquired assets to be a business if substantially all the fair value of the assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. A typical acquisition that we do not consider a business is a customer relationship asset acquisition, which does not have all elements necessary to operate a business, such as employees or infrastructure. Revenue from these customers acquired is included in organic revenue growth because we believe the efforts required to convert and retain these acquired customers are similar in nature to our efforts to obtain and retain our existing customer base. Comparable growth metrics - 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.

Projected 2026 comparable operating margin expansion outlined in the 2026 Growth and Financial Performance Outlook section of this earnings release reflects the following adjustments: (i) full year 2026 reported operating margin adjusted for a $5 million unfavorable impact of loss on an equity investment; (ii) adjustment to projected 2026 operating margin for a positive impact from year-over-year foreign currency exchange rate changes at noted exchange rates; and (iii) adjustment to 2025 operating margin for the positive impact of the approximately $9 million discrete litigation expense accrual adjustment in the first quarter of 2025. These impacts described above reconcile reported gross profit growth, gross margin gain, operating expense growth, operating profit growth and operating margin gain (including projected 2026) to comparable gross profit growth, comparable gross margin gain,

IDEXX Announces Third Quarter Results November 2, 2026 Page 9 of 17 Comparable EPS growth - 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: Three Months Ended Year-over-Year Nine Months Ended Year-over-Year September 30, September 30, September 30, September 30, 2026 2025 Growth 2026 2025 Growth Earnings per share (diluted) and growth $ 4.01 $ 3.40 18% $ 11.75 $ 9.99 18% Less: comparability adjustments Share-based compensation activity 0.01 0.17 0.24 0.28 Loss on equity investment — — (0.05) — Now-concluded litigation matter — — — 0.08 Change from currency 0.04 — 0.24 — Comparable EPS and growth $ 3.96 $ 3.24 22% $ 11.32 $ 9.63 18% Amounts presented may not recalculate due to rounding. Projected 2026 comparable EPS growth outlined in the 2026 Growth and Financial Performance Outlook section of this earnings release reflects the following adjustments: (i) adjustment to projected full year 2026 reported EPS for estimated positive year-over-year foreign currency exchange rate change impact of $0.25 at noted exchange rates; (ii) adjustment to projected full year 2026 reported EPS for estimated positive impact of share-based compensation activity of $0.24; (iii) adjustment to projected full year 2026 EPS of $0.05 for unfavorable impact of a loss on an equity investment; (iv) adjustment to full year 2025 reported EPS for a positive $0.08 impact from the discrete litigation expense accrual adjustment in the first quarter of 2025; and (v) adjustment to full year 2025 reported EPS for positive impact of share-based compensation activity of $0.35. These impacts and those described in the constant currency note above reconcile reported EPS growth (including projected 2026 reported EPS growth) to comparable EPS growth for the Company. Segment and Other Income from Operations - 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. The reconciliation of this non-GAAP financial measure is as follows for the three and nine months ended September 30, 2026 and 2025: Three Months Ended September 30, 2026 2025 Amounts in thousands Income from Operations Impact from Foreign Currency Segment and Other Income from Operations Income from Operations Impact from Foreign Currency Segment and Other Income from Operations CAG $ 370,216 $ (713) $ 369,503 $ 327,095 $ 1,376 $ 328,471 Water 29,624 (50) 29,574 26,311 104 26,415 LPD 1,948 (49) 1,899 364 107 471

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, 2026 and 2025. To estimate projected 2026 free cash flow, we have deducted projected purchases of property and equipment (also referred to as capital expenditures) of approximately $160 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, 2026, we have deducted purchases of property and equipment of approximately $115 million from net cash provided from operating activities of approximately $1,419 million, divided by net income of approximately $1,182 million. Notes and Definitions Discrete litigation expense accrual - During the first quarter of 2025, the Company reduced its previously established $89.0 million accrual related to a concluded litigation matter by approximately $9 million, which represented our best estimate at that time of the amount of the loss. Concluded litigation matter - 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.
