Solid growth supported by continued benefits from IDEXX execution drivers including double-digit year-over-year installed base growth across global premium instrument platforms

Delivers EPS of $2.81, reflecting operating margin contraction of 10 basis points as reported and on a comparable basis including ~180 basis point negative impact from lapping a customer contract resolution payment in Q1 2023

Updates 2024 revenue guidance to $3,895 million - $3,965 million, reflecting 6.5% - 8.5% growth as reported and 7% - 9% organic, driven by projected CAG Diagnostics recurring revenue growth of 6.5% - 8.5% as reported and 7.5% - 9.5% organic

Updates 2024 EPS outlook to $10.82 - $11.20, representing 8% - 11% growth as reported and 9% - 13% on a comparable basis, including ~2% negative EPS growth impact from Q1 2023 customer contract resolution payment

IDEXX Laboratories, Inc. (NASDAQ:IDXX), a global leader in pet healthcare innovation, today announced first quarter results.

First Quarter Results

The Company reports revenues of $964 million for the first quarter of 2024, an increase of 7% as reported and organic, driven by Companion Animal Group ("CAG") growth of 7% as reported and organic, and Water revenue growth of 11% as reported and organic. Overall IDEXX revenue gains were net of an estimated 0.5% - 1% negative growth rate impact from severe U.S. weather in January. CAG Diagnostics recurring revenue growth of 7% as reported and organic was supported by sustained benefits from IDEXX execution drivers. 8% global premium instrument placement growth and continued high customer retention levels supported 11% annual growth in IDEXX's global premium instrument installed base. High demand for IDEXX solutions drove veterinary software, services and diagnostic imaging systems revenue growth of 12% as reported, including benefits from a software and data platform acquisition completed in the period, and 8% organic growth, reflecting high recurring revenue growth and continued momentum in cloud-based software placements.

First quarter earnings per diluted share ("EPS") were $2.81, an increase of 10% as reported and 9% on a comparable basis, including ~7% negative EPS growth impact from the Q1 2023 customer contract resolution payment. Reported EPS included $0.10 per share in tax benefits from share-based compensation.

"High levels of execution from IDEXX teams drove strong results in the first quarter. This performance reflects continued high interest from customers in adopting IDEXX's innovative, multi-modality testing platforms and solutions," said Jay Mazelsky, President and Chief Executive Officer. "By partnering with IDEXX, veterinarians use the differentiated diagnostics insights generated by IDEXX solutions to deliver better patient outcomes, while also driving better business results through workflow optimization and staff productivity."

First Quarter Performance Highlights

Companion Animal Group

The Companion Animal Group generated revenue growth of 7% as reported and organic for the quarter. Solid growth was supported by CAG Diagnostics recurring revenue growth of 7% as reported and organic. U.S. CAG Diagnostics recurring revenue growth of 6.5% as reported and organic, which included impacts from severe weather in January, remained solidly above sector growth levels in the first quarter, reflecting a ~900 basis point growth premium to U.S. same-store clinical visit growth.

Additional U.S. companion animal practice key metrics are available in the Q1 2024 Earnings Snapshot accessible on the IDEXX website, www.idexx.com/investors.

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

IDEXX VetLab^® consumables generated 9% reported and organic revenue growth, with high single-digit gains in the U.S. and continued double-digit gains internationally supported by double-digit global premium instrument installed base growth across major platforms.

Reference laboratory diagnostic and consulting services generated 7% reported and 6% organic revenue growth, driven by similar solid gains across U.S. and international regions.

Rapid assay products revenues grew 5% as reported and organic, driven by solid gains in the U.S., supported by benefits from higher net price realization.

Veterinary software, services and diagnostic imaging systems revenues grew 12% as reported and 8% 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 11% as reported and organic for the quarter, reflecting solid gains across regions and benefits from year-end order shipment timing.

Livestock, Poultry and Dairy ("LPD")

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

Gross Profit and Operating Profit

Gross profits increased 9% as reported and on a comparable basis. Gross margin of 61.5% increased 120 basis points as reported and ~110 basis points on a comparable basis, supported by benefits from business mix, lower instrument costs and improvement in software service gross margins.

Operating margin was 31.0% for the quarter, lower than the prior year by 10 basis points as reported and on a comparable basis, including ~180 basis point negative impact from lapping a customer contract resolution payment in Q1 2023. Operating margin results reflect 12% operating expense growth as reported, including ~6.5% overall growth impact of the customer contract resolution payment in Q1 2023. Operating expense growth was driven by higher R&D spend related to advancing the Company's innovation agenda, including new platform development.

2024 Growth and Financial Performance Outlook

The Company is updating its full year revenue growth outlook range to 6.5% - 8.5% as reported and 7% - 9% organic, driven by a CAG Diagnostics recurring revenue growth outlook range of 6.5% - 8.5% as reported and 7.5% - 9.5% organic. This updated outlook includes a $35 million negative impact from the recent strengthening of the U.S. dollar and a reduction of 1% to the high end of the organic revenue growth range to reflect near-term moderation in U.S. clinical visit growth trends.

The Company maintained its full year reported operating margin outlook of 30.2% - 30.7%, reflecting continued high levels of operational execution. Projected full year operating margin profit expansion of 20 - 70 basis points is net of a ~40 basis point negative growth impact from lapping a customer contract resolution payment in Q1 2023.

The Company updated its EPS outlook range to $10.82 - $11.20, a reduction of $0.08 at midpoint, reflecting ~$0.11 of negative foreign exchange rate impact compared to previous guidance. Adjustments to the high end of the Company's organic revenue growth guidance range were mitigated by sustained expectations for operating margin improvement and favorable adjustments to projected net interest expense. The updated EPS growth outlook is 8% - 11% as reported and 9% - 13% on comparable basis, net of a ~2% negative growth impact from lapping a customer contract resolution payment in Q1 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 first quarter 2024 results as follows: increased gross profit growth by 0.1%, increased gross margin growth by 10 basis points, increased operating expense growth by 0.3%, decreased operating profit growth by 0.1%, was immaterial to operating profit margin growth, and was immaterial to EPS growth. 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 months ended March 31, 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 months ended March 31, 2024. Please refer to the constant currency note above for a summary of foreign currency exchange rate impacts. Please refer to the 2023 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 not expected to have an impact on projected full year 2024 revenue growth or 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:

	Three Months Ended						Year-over-Year
	March 31,			March 31,			Change
Dollar amounts in thousands		2024			2023
Gross Profit (as reported)	$	593,070		$	542,971		9%

*Comparable operating margin and operating margin gain (or growth)*		*31.0*	%		*31.1*	%	*(10) bps*
Amounts presented may not recalculate due to rounding.

Projected 2024 comparable operating margin expansion outlined in the 2024 Growth and Financial Performance Outlook section of this earnings release reflects immaterial impact from year-over-year foreign currency exchange rate changes.

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:

	Three Months Ended				Year-over-Year
	March 31,		March 31,		Growth
	2024		2023
Earnings per share (diluted)	$	2.81	$	2.55	*10%*
Less: comparability adjustments
Share-based compensation activity		0.10		0.06
Change from currency		—		—
Comparable EPS growth		2.71		2.49	9%
Amounts presented may not recalculate due to rounding.

Projected 2024 comparable EPS growth outlined in the 2024 Growth and Financial Performance Outlook section of this earnings release reflects adjustments including estimated positive share-based compensation activity of $0.12 and estimated negative year-over-year foreign currency exchange rate change impact of $0.09.

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 months ended March 31, 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 ~ $180 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 March 31, 2024, we have deducted purchases of property and equipment of approximately $124 million from net cash provided from operating activities of approximately $921 million, divided by net income of approximately $867 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 March 31, 2024.
