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 $944 million for the second quarter of 2023, an increase of 10% reported and 10% organic, driven by Companion Animal Group ("CAG") growth of 11% reported and organic and Water revenue growth of 10% reported and 9% organic. CAG Diagnostics recurring revenue growth of 11% reported and 12% organic was supported by double-digit organic revenue growth in U.S. and international regions, reflecting solid demand for veterinary services and benefits from IDEXX execution drivers. IDEXX innovation and commercial engagement drove record second 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 12% as reported and 13% organically, reflecting continued high growth in recurring revenues and strong quarterly placements of cloud-based software solutions.

Second quarter earnings per diluted share (“EPS”) were $2.67, an increase of 71% as reported and 77% on a comparable basis, including 54% growth benefit from lapping prior year discrete R&D investments in the second quarter of 2022. EPS results included $0.04 per share in tax benefits from share-based compensation, and $0.07 per share negative impact from currency changes.

"Strong execution by IDEXX commercial and operational teams drove excellent growth results and financial performance in the second quarter," said Jay Mazelsky, President and Chief Executive Officer.

Second Quarter Performance Highlights

Companion Animal Group

The Companion Animal Group generated revenue growth of 11% reported and organic for the quarter. Strong growth performance was supported by CAG Diagnostics recurring revenue growth of 11% on a reported basis and 12% organically. U.S. CAG Diagnostics organic recurring revenue growth of 12% remained solidly above sector growth levels in the second quarter, reflected in an estimated 1,370 basis point growth premium to U.S. same store clinical visit growth.

Additional U.S. companion animal practice key metrics are available in the Q2 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 14% reported and 15% 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 9% reported and 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 11% 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 12% as reported and 13% 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 10% on a reported basis and 9% on an organic basis for the quarter, reflecting solid gains across regions, including benefits from net price improvement.

Livestock, Poultry and Dairy (“LPD”)

LPD revenues were flat on a reported basis and grew 1% organically for the quarter, as solid gains in the U.S. were offset by lower herd health screening levels.

Gross Profit and Operating Profit

Gross profits increased 11% as reported and 13% on a comparable basis. Gross margin of 60.7% increased 100 basis points as reported and 160 basis points on a comparable basis. Benefits from net price gains, lab productivity and operational initiatives, improvement in software service gross margins and business mix offset inflationary effects.

Operating margin was 31.4% in the quarter, 1,060 basis points higher than the prior year as reported and 1,130 basis points higher on a comparable basis including a 930 basis point benefit from lapping prior year discrete R&D investments. Operating margin expansion reflects gross margin gains benefiting from strong CAG Diagnostics recurring revenue growth and operating expense declines of 17% as reported and on a comparable basis. Reported operating expense declines include a 26% growth impact from lapping prior year discrete R&D investments. Adjusting for this impact, operating expense growth was modestly below revenue growth, supporting operating margin gains.

2023 Growth and Financial Performance Outlook

The Company is updating its full year revenue growth outlook range to 8.5% - 10% as reported and organically. This reflects no changes to the outlook for organic revenue growth at the high end of the range and an increase of 1% at the low end. The overall reported revenue range was increased by $15 million for updated foreign exchange impact estimates.

The Company refined its full year reported operating margin outlook to 29.3% - 29.7%, incorporating strong first half performance. Operating margin guidance includes a consistent ~60 basis points in year-over-year unfavorable net margin impact from updated foreign currency exchange rate changes, including effects from comparisons to prior year foreign exchange hedge gains.

The Company's higher EPS outlook range of $9.64 - $9.90 increased $0.31 at the low end and $0.15 at the high end, incorporating positive refinements to the full year operational outlook and benefits of $0.06 combined from updated projections for interest expense, foreign exchange impacts, and share-based compensation benefits. This includes an outlook for $0.21 of negative full year impact from foreign exchange changes, primarily related to lapping 2022 hedge gains, an improvement of $0.02 per share compared to prior guidance.

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 2023 results as follows: decreased gross profit growth by 2%, decreased gross margin growth by 60 basis points, decreased operating expense growth by 0%, decreased operating profit growth by 4%, decreased operating profit margin growth by 70 basis points, and decreased EPS growth by 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 months and six months ended June 30, 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 and six months ended June 30, 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 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 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 $0.11 and estimated negative year-over-year foreign currency exchange rate change impact of $0.21.

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 and six months ended June 30, 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 June 30, 2023, we have deducted purchases of property and equipment of approximately $154 million from net cash provided from operating activities of approximately $747 million, divided by net income of approximately $791 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 June 30, 2023.
