WESTBROOK, Maine / May 02, 2023 / Business Wire / 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 $900 million for the first quarter of 2023, an increase of 8% reported and 10% organic, driven by Companion Animal Group ("CAG") Diagnostics recurring revenue growth of 9% reported and 12% organic. First quarter results were supported by continued solid demand for veterinary services and benefits from strong IDEXX execution, reflected in 14% reported and organic growth in U.S. CAG Diagnostics recurring revenues and double-digit organic gains across IDEXX's major testing modalities. IDEXX innovation and commercial engagement drove record first quarter global premium instrument placements, supporting 11% annual growth in IDEXX's global premium instrument installed base. Veterinary software, services and diagnostic imaging systems revenue grew 13% as reported and 14% organically, reflecting high growth in recurring revenues and continued strong quarterly placements of cloud-based software solutions. Overall first quarter revenue gains were also supported by Water revenue growth of 7% reported and 8% organic.

First quarter earnings per diluted share (“EPS”) were $2.55, an increase of 12% as reported and 18% on a comparable basis, reflecting solid gross margin gains and benefits from a $16 million customer contract resolution payment. EPS results included $0.06 per share in tax benefits from share-based compensation, and $0.11 per share negative impact from currency changes.

"Strong execution by IDEXX commercial and operational teams drove excellent growth results and financial performance in the first quarter," said Jay Mazelsky, President and Chief Executive Officer. "Commercial engagement and IDEXX innovations are supporting our customers as they work to address growing demand for pet healthcare. IDEXX's ongoing focus on addressing the needs of veterinary clinics is aligned with developing the long-term global growth opportunity for companion animal diagnostics.”

First Quarter Performance Highlights

Companion Animal Group

The Companion Animal Group generated revenue growth of 9% reported and 11% organic for the quarter. Strong growth performance was supported by CAG Diagnostics recurring revenue growth of 9% on a reported basis and 12% organically. U.S. CAG Diagnostics organic recurring revenue growth of 14% remained solidly above sector growth levels in the first quarter, reflected in a 1,350 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 2023 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 12% organic revenue growth, with strong gains across U.S. and international regions supported by benefits from higher net price realization and an expanded global premium instrument installed base.

• Reference laboratory diagnostic and consulting services generated 10% reported and 11% organic revenue growth, driven by strong gains in the U.S. and moderate overall growth in international regions. International growth was constrained by pressure on same-store clinical visit levels, reflecting ongoing macro-economic impacts.

• Rapid assay products revenues grew 10% as reported and 12% organically, driven by strong growth in the U.S. reflecting solid volume gains and benefits from higher net price realization.

Veterinary software, services and diagnostic imaging systems revenues grew 13% as reported and 14% organically, supported by double-digit organic gains in recurring software and digital imaging revenues. Strong demand for cloud-based products continues to support momentum in software solution placements and customer gains.

Water

Water revenues grew 7% on a reported basis and 8% on an organic basis for the quarter, reflecting solid volume gains in the U.S. and key international regions, including benefits from net price improvement.

Livestock, Poultry and Dairy (“LPD”)

LPD revenues declined 5% as reported and 2% organically for the quarter, as solid gains in the U.S. and Europe were offset by comparison to high prior year herd health screening levels and reduced revenues from non-core food and safety products in certain regions.

Gross Profit and Operating Profit

Gross profits increased 9% as reported and 12% on a comparable basis. Gross margin of 60.3% increased 70 basis points as reported and 120 basis points on a comparable basis. Benefits from net price gains, lab productivity initiatives, improvement in software service gross margins and business mix offset inflationary effects.

Operating margin was 31.1% in the quarter, 150 basis points higher than the prior year as reported and 210 basis points higher on a comparable basis, reflecting gross margin gains and benefits from a $16 million customer contract resolution payment. Operating expense grew 5% as reported and 7% on a comparable basis, net of a ~6% favorable growth rate impact from the customer contract resolution payment. Operating expense growth was driven by higher levels of sales and marketing spending, including impacts from the return of in-person sales meetings, and R&D investments.

2023 Growth and Financial Performance Outlook

The Company is updating its full year revenue growth outlook range to 7.5% - 10% as reported and organically. This reflects consistent goals for organic revenue growth at the high end and an increase of 0.5% at the low end. The overall reported revenue range was also increased by $10 million, or ~0.5%, for updated foreign exchange effects.

The Company refined its full year reported operating margin outlook to 29.0% - 29.5%. The operating margin guidance range includes an estimated 60 basis points in year-over-year unfavorable net margin impact from updated foreign currency exchange rate changes, ~10 basis points higher than earlier estimates.

The Company's EPS outlook range of $9.33 - $9.75 maintains a consistent high end estimate and raises the low end by $0.06 to reflect the factors noted above. This includes a consistent outlook for $0.23 of full year impact from foreign exchange changes, primarily related to lapping 2022 hedge gains.

The following table provides the Company's updated outlook for annual key financial metrics in 2023:

The following table outlines estimates of foreign currency exchange rate impacts, net of foreign currency hedging transactions, and foreign currency exchange rate assumptions reflected in the above financial performance outlook for 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 2023 results as follows: decreased gross profit growth by 3%, decreased gross margin growth by 50 basis points, decreased operating expense growth by 2%, decreased operating profit growth by 5%, decreased operating profit margin growth by 60 basis points, and decreased EPS growth by 5%. 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, 2023 and refer to the 2023 Growth and Financial Performance Outlook section of this earnings release for estimated foreign currency exchange rate impacts on 2023 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, 2023. 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 2023 organic revenue growth for the Company and CAG Diagnostics recurring revenue. 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 2023 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:

Projected 2023 comparable operating margin expansion outlined in the 2023 Growth and Financial Performance Outlook section of this earnings release reflects projected full year 2023 reported operating margin adjusted for estimated positive year-over-year foreign currency exchange rate change impact of approximately 60 basis points.

These impacts described above reconcile reported gross profit growth, gross margin gain, operating expense growth, operating profit growth and operating margin gain (including projected 2023 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 2023 comparable EPS growth outlined in the 2023 Growth and Financial Performance Outlook section of this earnings release reflects adjustments including estimated positive share-based compensation activity of $0.10 and estimated negative year-over-year foreign currency exchange rate change impact of $0.23.

These impacts and those described in the constant currency note above reconcile reported EPS growth (including projected 2023 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, 2023 and 2022. To estimate projected 2023 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, 2023, we have deducted purchases of property and equipment of approximately $157 million from net cash provided from operating activities of approximately $612 million, divided by net income of approximately $699 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, 2022 and Quarterly Report on Form 10-Q for the quarter ended March 31, 2023.
