CAG Diagnostics recurring revenue growth of 7% as reported and organic was supported by sustained double-digit growth in international regions and global benefits from IDEXX execution drivers including 10% annual growth in IDEXX's global premium instrument installed base. IDEXX veterinary software, services and diagnostic imaging systems revenue increased 11% as reported and 6% organic, reflecting high recurring revenue growth and continued momentum in cloud-based software placements.

“IDEXX teams continued their strong execution in the third quarter as demonstrated by solid net customer gains, continued growth in our premium IDEXX VetLab® instrument installed base, and nearly 700 pre-orders of IDEXX inVue Dx™ Cellular Analyzer, which will begin shipping later in the fourth quarter,” said Jay Mazelsky, President and Chief Executive Officer. "Customers especially value IDEXX technology solutions like inVue Dx that provide meaningful clinical insights while giving time back to busy practice staff.”

Third Quarter Performance Highlights

Companion Animal Group

The Companion Animal Group generated revenue growth of 7% as reported and 6% organic for the quarter. Solid growth was supported by CAG Diagnostics recurring revenue growth of 7% as reported and organic. CAG Diagnostics recurring revenue growth was supported by 10% reported and organic gains in international regions. U.S. CAG Diagnostics recurring revenue growth of 5% as reported and organic continued to outpace sector growth levels in the third quarter.

Additional U.S. companion animal practice key metrics are available in the Q3 2024 Earnings Snapshot accessible on the IDEXX website, www.idexx.com/investors.

Solid global growth was achieved across IDEXX's testing modalities.

• IDEXX VetLab® consumables generated 11% reported and organic revenue growth, with double-digit gains in the U.S. and International regions supported by strong installed base growth across premium instrument platforms and benefits from equivalent days effects.

• Reference laboratory diagnostic and consulting services generated 3% reported and 2% organic revenue growth, driven by solid International growth.

• Rapid assay products revenues grew 6% as reported and organic, driven by solid gains in the U.S., including benefits from higher net price realization and equivalent days effects.

Veterinary software, services and diagnostic imaging systems revenues grew 11% as reported and 6% organically, driven by continued high levels of organic growth in software and diagnostic imaging recurring revenues and benefits from a recent software and data platform acquisition.

Water

Water revenues grew 13% as reported and organic for the quarter, reflecting double-digit gains in the U.S. and continued solid growth in Europe.

Livestock, Poultry and Dairy (“LPD”)

LPD revenues declined 3% as reported and 2% organic for the quarter. Solid gains in the U.S. and for poultry tests globally were offset by lower Asia Pacific revenues, including impacts from reduced swine testing and herd health screening levels.

Gross Profit and Operating Profit

Gross profits increased 9% as reported and on a comparable basis. Gross margin of 61.1% increased 120 basis points as reported and 140 basis points on a comparable basis supported by benefits from business mix, led by high growth in IDEXX VetLab consumable revenues and veterinary software, services, and diagnostic imaging recurring revenues and lower instrument costs.

Operating margin was 31.2% for the quarter, higher than the prior year by 110 basis points as reported and 100 basis points on a comparable basis. Operating margin results reflect 7% operating expense growth as reported and 8% on a comparable basis. Operating expense growth was driven by higher sales and marketing expense and higher R&D spend related to advancing the Company's growth and innovation agenda.

2024 Growth and Financial Performance Outlook

The Company is updating its full year revenue growth guidance range to $3,865 million - $3,890 million, or reported growth of 5.5% - 6.2%, a reduction of $38 million at midpoint. This reflects an adjustment of ~1.5% at midpoint to full year estimates for organic revenue growth, which is now projected at 5.3% - 6.0%, reflecting recent trends in U.S. clinical visit and demand levels. The updated guidance range includes ~$15 million of favorable impact from more recent foreign exchange estimates.

The Company maintained a consistent full year reported operating margin outlook of 28.7% - 29.0%, including ~160 basis points of impact related to the previously reported discrete litigation expense accrual. At midpoint, projected full year comparable operating profit margin expansion of 30 - 60 basis points includes a ~40 basis point negative growth impact from lapping a customer contract resolution payment in the first quarter of 2023.

The Company narrowed its EPS outlook range to $10.37 - $10.53, maintaining a consistent midpoint. 2024 EPS results include a $0.56 negative impact from a discrete litigation expense accrual recorded in the second quarter. Negative EPS impacts related to adjustments to the organic revenue outlook were offset by $0.02 in favorable adjustments to foreign exchange estimates and favorable refinements to interest expense and effective tax rate estimates. The updated EPS growth outlook is 3% - 5% as reported and 10% - 11% on comparable basis, including a ~2% negative growth impact from lapping a customer contract resolution payment in the first quarter of 2023.

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.

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 estimated 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 2024 results as follows: decreased gross profit growth by 0.2%, decreased gross margin growth by 20 basis points, decreased operating expense growth by 0.8%, increased operating profit growth by 0.4%, increased operating profit margin growth by 10 basis points, and increased EPS growth by 0.4%. 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, 2024 and refer to the 2024 Growth and Financial Performance Outlook section of this earnings release for estimated foreign currency exchange rate impacts on 2024 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 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, 2024. Please refer to the constant currency note above for a summary of foreign currency exchange rate impacts. Please refer to the 2024 Growth and Financial Performance Outlook section of this earnings release for estimated full year 2024 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 benefit projected full year 2024 revenue growth by 0.4% and have no impact on CAG Diagnostics recurring revenue growth.

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.

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

Projected 2024 comparable operating margin expansion outlined in the 2024 Growth and Financial Performance Outlook section of this earnings release reflects: (i) projected full year 2024 reported operating margin is adjusted for impacts of the discrete expense accrual related to an ongoing litigation matter in the second quarter of 2024; and (ii) projected full year 2024 reported operating margin includes an immaterial impact from year-over-year foreign currency exchange rate changes at noted exchange rates.

These impacts described above reconcile reported gross profit growth, gross margin gain, operating expense growth, operating profit growth and operating margin gain (including projected 2024 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.

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:

Projected 2024 comparable EPS growth outlined in the 2024 Growth and Financial Performance Outlook section of this earnings release reflects adjustments to projected full year 2024 reported EPS for: (i) estimated positive share-based compensation activity of ~$0.11; (ii) a negative $0.56 impact from a discrete expense accrual related to an ongoing litigation matter in the second quarter of 2024; and (iii) estimated negative year-over-year foreign currency exchange rate change impact of ~$0.03 at noted exchange rates.

These impacts and those described in the constant currency note above reconcile reported EPS growth (including projected 2024 reported EPS growth) to comparable EPS growth for the Company.

Free cash flow - 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, 2024 and 2023. To estimate projected 2024 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, 2024, we have deducted purchases of property and equipment of approximately $124 million from net cash provided from operating activities of approximately $917 million, divided by net income of approximately $866 million.

Debt to Adjusted EBITDA (Leverage Ratios) - 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, 2023 and Quarterly Report on Form 10-Q for the quarter ended September 30, 2024.

Notes and Definitions

Discrete litigation expense accrual - During the second quarter of 2024, the Company increased its previously established $27.5 million accrual related to an ongoing litigation matter by $61.5 million.

Ongoing litigation matter - The Company is a defendant in an ongoing litigation matter involving an alleged breach of contract for underpayment of royalty payments made from 2004 through 2017 under an expired patent license agreement. The Company's total accrual of $89.0 million for this matter includes the discrete $61.5 million litigation expense accrual recorded in the second quarter of 2024 and represents our best estimate of the amount of the probable loss. The actual loss associated with this matter may be higher or lower than the accrued amount depending on the ultimate outcome of this matter. For further information, see the Company's Quarterly Report on Form 10-Q for the quarter ended September 30, 2024.
