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

Second Quarter Results

The Company reports revenues of $1,004 million for the second quarter of 2024, an increase of 6% as reported and 7% organic, driven by Companion Animal Group ("CAG") growth of 6% as reported and 7% organic, and Water revenue growth of 9% as reported and 10% organic. CAG Diagnostics recurring revenue growth of 6% as reported and 7% organic was supported by strong growth in international regions and sustained global benefits from IDEXX execution drivers. IDEXX veterinary software, services and diagnostic imaging systems revenue increased 12% as reported and 8% organic, reflecting high recurring revenue growth and continued momentum in cloud-based software placements. Strong interest in IDEXX solutions supported record second quarter premium instrument placements and 11% annual growth in IDEXX's global premium instrument installed base.

Second quarter earnings per diluted share ("EPS") were $2.44, a decrease of 9% as reported and an increase of 15% on a comparable basis excluding a $0.56 per share impact related to a discrete expense accrual for an ongoing litigation matter.

"Continued high levels of execution from IDEXX teams drove solid global growth and strong operational performance in the second quarter," said Jay Mazelsky, President and Chief Executive Officer. "These results reflect the benefits that IDEXX customers gain from adopting our innovative, multi-modality testing platforms and solutions. Veterinarians appreciate the deep diagnostics insights generated by IDEXX solutions, which help them deliver better patient outcomes and seamless workflow for better business results. This value-added partnership, supported by IDEXX innovation, sets a strong foundation for long-term growth through higher standards of pet healthcare."

Second Quarter Performance Highlights

Companion Animal Group

The Companion Animal Group generated revenue growth of 6% as reported and 7% organic for the quarter. Solid growth was supported by CAG Diagnostics recurring revenue growth of 6% as reported and 7% organic. CAG Diagnostics recurring revenue growth was supported by 8% reported and 10% organic gains in international regions. U.S. CAG Diagnostics recurring revenue growth of 5% as reported and organic remained solidly above sector growth levels in the second quarter.

Additional U.S. companion animal practice key metrics are available in the Q2 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 7% reported and 8% organic revenue growth, with solid gains in the U.S. and continued double-digit organic gains internationally supported by strong installed base growth across premium instrument platforms.

Reference laboratory diagnostic and consulting services generated 5% reported and 6% organic revenue growth, driven by solid U.S. gains and high single-digit organic growth in international regions.

Rapid assay products revenues grew 6% 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 9% as reported and 10% organic for the quarter, reflecting strong growth in the U.S. and Europe.

Livestock, Poultry and Dairy ("LPD")

LPD revenues grew 1% as reported and 3% organically for the quarter. Solid gains in the U.S. and Europe were partially 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 8% as reported and 9% on a comparable basis. Gross margin of 61.7% increased 100 basis points as reported and 90 basis points on a comparable basis, supported by benefits from net price realization offsetting inflationary cost impacts, software service margin gains and favorable business mix.

Operating margin was 26.3% for the quarter, lower than the prior year by 510 basis points including ~610 basis point negative impact from $62 million of expense related to a discrete litigation expense accrual. On a comparable basis excluding this item and foreign exchange effects, operating margins increased 110 basis points. Operating margin results reflect 28% operating expense growth as reported and 7% on a comparable basis excluding expense related to the discrete litigation accrual.

2024 Growth and Financial Performance Outlook

The Company is updating its full year revenue growth guidance range to $3,885 million to $3,945 million, or reported growth of 6.2% - 7.8%, a reduction of $15 million at midpoint. This reflects an adjustment of ~1% at midpoint to full year estimates for organic revenue growth, which is now projected at 6.2% to 7.8%, reflecting recent trends in U.S. clinical visit levels. The updated guidance range includes ~$15 million of favorable impact from more recent foreign exchange estimates.

The Company updated its full year reported operating margin outlook to reflect consistent midpoint goals for comparable operating margin improvement and to incorporate the expenses related to an ongoing litigation matter. The Company's reported operating margin outlook is 28.7% - 29.0%, including ~160 basis points of impact related to the 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 updated its EPS outlook range to $10.31 - $10.59, a reduction of $0.56 at midpoint, reflecting a $0.56 negative impact from a discrete litigation expense accrual. Adjustments to the organic revenue outlook were offset by $0.04 in favorable adjustments to foreign exchange estimates and favorable refinements to interest expense and effective tax rate estimates. The updated EPS growth outlook is 2% - 5% as reported and 9% - 12% 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 second quarter 2024 results as follows: decreased gross profit growth by 0.7%, increased gross margin growth by 10 basis points, decreased operating expense growth by 0.4%, decreased operating profit growth by 0.9%, decreased operating profit margin growth by 10 basis points, and decreased EPS growth by 0.7%. 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 six months ended June 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 six months ended June 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 not expected to have benefit projected full year 2024 revenue growth by 0.5% 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:

	Three Months Ended					Year-over-Year	Six Months Ended					Year-over-Year
	June 30,			June 30,		Growth	June 30,			June 30,		Growth
	2024			2023			2024			2023
Earnings per share (diluted)	$	2.44		$	2.67	*(9)%*	$	5.24		$	5.22	—%

Change from currency		(0.02	)		—			(0.03	)		—
Comparable EPS growth		3.02			2.63	*15%*		5.73			5.12	*12%*
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 to projected full year 2024 reported EPS for: (i) estimated positive share-based compensation activity of ~$0.12; (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 ~$0.05 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 six months ended June 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 $180. 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 June 30, 2024, we have deducted purchases of property and equipment of approximately $130 million from net cash provided from operating activities of approximately $969 million, divided by net income of approximately $846 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 June 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 June 30, 2024.
