NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1. BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION

The accompanying unaudited condensed consolidated financial statements of IDEXX Laboratories, Inc. and its subsidiaries have been prepared in accordance with U.S. GAAP for interim financial information and with the requirements of Regulation S-X, Rule 10-01 for financial statements required to be filed as a part of this Quarterly Report on Form 10-Q. Unless the context requires otherwise, references in this Quarterly Report on Form 10-Q to “IDEXX,” the “Company,” “we,” “our,” or “us” refer to IDEXX Laboratories, Inc. and its subsidiaries.

The accompanying unaudited condensed consolidated financial statements include the accounts of IDEXX Laboratories, Inc., and our wholly-owned subsidiaries. We do not have any variable interest entities for which we are the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation.

Changes in deferred revenue during the nine months ended September 30, 2025, were reclassified and aggregated with other assets and liabilities to reconcile net income to net cash provided by operating activities on the unaudited condensed consolidated statements of cash flows to conform to the current‑period presentation. The reclassification had no impact on net cash provided by operating activities for any period presented.

The accompanying unaudited condensed consolidated financial statements reflect, in the opinion of our management, all adjustments necessary for a fair statement of our financial position and results of operations. All such adjustments are of a recurring nature. The condensed consolidated balance sheet data as of December 31, 2025, was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. The results of operations for the three and nine months ended September 30, 2026, are not necessarily indicative of the results to be expected for the full year or any future period. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2025 (the “2025 Annual Report”).

The preparation of our condensed consolidated financial statements requires us to make estimates, judgments, and assumptions that may affect the reported amounts of assets, liabilities, equity, revenues, and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, judgments, assumptions, and methodologies. We base our estimates on historical experience and on various other assumptions that we believe are reasonable, the results of which form the basis for making judgments about the carrying values of assets, liabilities, and equity, and the amounts of revenues and expenses.

NOTE 2. ACCOUNTING POLICIES

Significant Accounting Policies

The significant accounting policies used in preparation of these unaudited condensed consolidated financial statements as of and for the three and nine months ended September 30, 2026, are consistent with those discussed in “Note 2. Summary of Significant Accounting Policies” to the consolidated financial statements in our 2025 Annual Report and as updated below.

New Accounting Pronouncements Adopted

In July 2025, the U.S. Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2025-05, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets.” We adopted ASU 2025-05 effective January 1, 2026, with no material impact on our consolidated financial statements and related disclosures.

New Accounting Pronouncements Not Yet Adopted

In May 2026, the FASB issued ASU 2026-02, “Environmental Credits and Environmental Credit Obligations (Topic 818),” to clarify the accounting for and disclosure of environmental credits and environmental credit obligations. ASU 2026-02 is effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period and should be applied on a retrospective basis. We do not expect the adoption of ASU 2026-02 to have a material impact on our consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU 2025-10, “Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities,” which establishes authoritative guidance on the recognition, measurement, and presentation of government grants received by business entities. Under the ASU, a government grant is recognized when (1) it is probable the business entity will comply with the conditions of the grant and the grant will be received, and (2) the business entity meets the recognition guidance for a grant related to an asset or to income. ASU 2025-10 is effective for annual reporting periods beginning after December 15, 2028, and interim reporting periods within those annual reporting periods, with early adoption permitted. We are currently evaluating the timing of adoption and do not expect the adoption of ASU 2025-10 to have a material impact on our consolidated financial statements or related disclosures.

In September 2025, the FASB issued ASU 2025-06, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software,” which amends the existing standard related to accounting for internal-use software development costs. The amendments modernize the recognition and capitalization framework to better align with current software development practices by removing references to project stages and clarify the criteria for capitalization, which begins when (1) management has authorized and committed to funding the software project, and (2) it is probable that the project will be completed and the software will be used to perform the function intended. ASU 2025-06 is effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, with early adoption permitted. We are currently evaluating the timing of adoption and do not expect the adoption of ASU 2025-06 to have a material impact on our consolidated financial statements or related disclosures.

In November 2024, the FASB issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses,” to require disaggregated disclosures of specific expense categories underlying all relevant income statement expense line items on an annual and interim basis. The disclosure requirements will apply on a prospective basis, with the option to apply them retrospectively. This standard is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. We are evaluating ASU 2024-03 to determine its impact on the disclosures in our consolidated financial statements.

Contracts with Multiple Performance Obligations

We enter into arrangements with multiple performance obligations where customers purchase a combination of IDEXX products and services. We apply judgment to determine whether products and services are considered distinct performance obligations that should be accounted for separately. We determine the transaction price for a contract based on the total consideration we expect to receive in exchange for the transferred goods or services. To the extent the transaction price includes variable consideration, such as volume rebates or expected price adjustments, we apply judgment in constraining the estimated variable consideration due to factors that may cause reversal of revenue recognized. We evaluate constraints based on our historical and projected experience with similar customer arrangements.

We allocate revenue to each performance obligation in proportion to the relative standalone selling prices and recognize revenue when control of the related goods or services is transferred for each obligation. We utilize the observable standalone selling price when available, which represents the price charged for the promised product or service when sold separately. When standalone selling prices for our products or services are not directly observable, we determine the standalone selling prices using relevant information available and apply suitable estimation methods including, but not limited to, the cost plus a margin approach. We recognize revenue as each performance obligation is satisfied, either at a point in time or over time. We do not disclose information about remaining performance obligations that are part of arrangements with an original expected duration of one year or less.

The following customer arrangements represent our most significant customer contracts that contain multiple performance obligations:

Customer Commitment Arrangements. We offer customers incentives upon entering into multi-year arrangements to purchase minimum annual amounts of products and services.

Free or Discounted Instruments and Systems. Many of our customer commitment arrangements provide customers with free or discounted instruments or systems upon entering into multi-year arrangements to purchase minimum annual amounts of products and services. We allocate total consideration, including future committed purchases and expected price adjustments, based on relative standalone selling prices to identified performance obligations and recognize instrument revenue and cost at the time of installation and customer acceptance in advance of billing the customer, which is also when the customer obtains control of the instrument based on legal title transfer. Our right to future consideration related to instrument revenue is recorded as a contract asset within other current and long-term assets. The contract assets are reclassified to accounts receivable when customers are billed for products and services over the term of the arrangement. We have determined that these arrangements do not include a significant financing component.

On December 31, 2025, our contract assets were $312.7 million, of which approximately $19.9 million and $60.9 million were reclassified to accounts receivable when customers were billed for related products and services during the three and nine months ended September 30, 2026, respectively, compared to $15.5 million and $47.7 million during the three and nine months ended September 30, 2025, respectively. Furthermore, as a result of new instrument placements under commitment arrangements, net of subsequent amounts reclassified to accounts receivable, and allowances established for credit losses, our contract assets were $348.9 million as of September 30, 2026. We monitor customer purchases over the term of their arrangement to assess the realizability of our contract assets and review estimates of variable consideration. Impairments and revenue adjustments that relate to performance obligations satisfied in prior periods, including cumulative catch-up adjustments to revenue arising from contract modifications, during the three and nine months ended September 30, 2026 and 2025, were not material.

Up-Front Consideration Paid to Customers. We provide customers with incentives in the form of IDEXX Points upon entering into multi-year arrangements to purchase minimum annual amounts of future products and services. If a customer breaches their agreement, they are required to refund all or a portion of the up-front consideration, or make other repayments, remedial actions, or both. Up-front incentives to customers in the form of IDEXX Points or, to a lesser degree, cash payments, are not made in exchange for distinct goods or services and are capitalized as consideration paid to customers within other current and long-term assets, which are subsequently recognized as a reduction to revenue over the term of the customer arrangement. If these up-front incentives are subsequently utilized to purchase instruments, we allocate total consideration, including future committed purchases less up-front incentives and estimates of expected price adjustments, based on relative standalone selling prices, to identified performance obligations, and recognize instrument revenue and cost at the time of installation and customer acceptance. To the extent invoiced instrument revenue exceeds recognized instrument revenue, we record deferred revenue as a contract liability, which is subsequently recognized upon the purchase of products and services over the term of the contract. We have determined these arrangements do not include a significant financing component.

On December 31, 2025, our capitalized consideration paid to customers was $250.1 million, of which approximately $18.2 million and $56.0 million was recognized as a reduction of revenue during the three and nine months ended September 30, 2026, respectively, compared to $15.2 million and $47.5 million during the three and nine months ended September 30, 2025, respectively. Furthermore, as a result of new payments to customers, net of subsequent recognition, our capitalized consideration paid to customers was $276.9 million as of September 30, 2026. We monitor customer purchases over the term of their arrangement

to assess the realizability of capitalized consideration paid to customers and review estimates of variable consideration. Impairments and revenue adjustments that relate to performance obligations satisfied in prior periods, including cumulative catch-up adjustments to revenue arising from contract modifications, during the three and nine months ended September 30, 2026 and 2025, were not material.

Rebate Arrangements. Our rebate arrangements provide customers the opportunity to earn future rebates based on the volume of products and services they purchase over the term of the arrangement. Rebate incentives are typically offered in multi-year arrangements that include customer commitments to purchase minimum annual amounts of products and services, or, to a lesser extent, are sometimes offered without future purchase commitments. We account for the customer’s right to earn rebates on optional future purchases that are determined to be a material right as a separate performance obligation and estimate the standalone selling price, which represents the expected value to the customer, based on historical rebate experience, the contractual rebate structure and terms, and other relevant information. Total consideration allocated to identified performance obligations is limited to goods and services that the customer is presently obligated to purchase and does not include estimates of future purchases that are optional. We allocate total consideration to identified performance obligations, including the customer’s right to earn rebates on future purchases, which is deferred and subsequently recognized upon the customer’s purchase of eligible products and services.

On December 31, 2025, our deferred revenue related to rebate and up-front consideration arrangements was $35.3 million, of which approximately $2.6 million and $7.8 million were recognized when customers purchased eligible products and services during the three and nine months ended September 30, 2026, respectively, compared to $2.5 million and $7.9 million during the three and nine months ended September 30, 2025, respectively. Furthermore, as a result of new customer purchases under rebate and up-front consideration arrangements, net of subsequent recognition, our deferred revenue was $35.5 million as of September 30, 2026, of which approximately 8%, 29%, 23%, 18%, and 22% are expected to be recognized during the remainder of 2026, the full years 2027, 2028, 2029, and thereafter, respectively.

For our customer commitment arrangements, we estimate future revenues related to multi-year arrangements to be approximately $5.3 billion, of which approximately 7%, 28%, 25%, 18%, and 22% are expected to be recognized during the remainder of 2026, the full years 2027, 2028, 2029, and thereafter, respectively. These future revenues relate to performance obligations not yet satisfied, for which customers have committed to future purchases, net of the expected revenue reductions from consideration paid to customers and expected price adjustments, and as a result, are lower than stated contractual commitments by our customers.

Instrument Rental Arrangements. Revenues from instrument rental and reagent rental arrangements are recognized either as operating leases on a ratable basis over the term of the arrangement or as sales-type leases at the time of installation and customer acceptance. Customers typically pay for the right to use instruments under rental arrangements in equal monthly amounts over the term of the rental arrangement. For some arrangements, customers are provided with the right to purchase the instrument at the end of the lease term. Our reagent rental arrangements provide customers the right to use our instruments upon entering into multi-year arrangements to purchase minimum annual amounts of consumables. These types of arrangements include an embedded lease for the right to use our instrument, and we determine the amount of lease revenue allocated to the instrument based on relative standalone selling prices. Lease revenues are presented in product revenue on our consolidated income statement. Lease revenues were approximately $5.8 million and $13.5 million for the three and nine months ended September 30, 2026, respectively, compared to $4.8 million and $11.8 million for the three and nine months ended September 30, 2025, respectively, including both operating leases and sales-type leases.

Sales-type Reagent Rental Arrangements. Our reagent rental arrangements that effectively transfer control of instruments to our customers are classified as sales-type leases, and we recognize instrument revenue and cost in advance of billing the customer at the time of installation and customer acceptance. Our right to future consideration related to instrument revenue is recorded as a lease receivable within other current and long-term assets, and is reclassified to accounts receivable when customers are billed for products and services over the term of the arrangement. On December 31, 2025, our lease receivable assets were $18.0 million, of which approximately $1.2 million and $3.8 million was reclassified to accounts receivable when customers were billed for related products and services during the three and nine months ended September 30, 2026, respectively, compared to $1.3 million and $4.0 million for the three and nine months ended September 30, 2025, respectively. Furthermore, as a result of new instrument placements under sales-

type reagent rental arrangements, net of subsequent amounts reclassified to accounts receivable, and allowances established for credit losses, our lease receivable assets were $20.7 million as of September 30, 2026. The impacts of discounting and unearned income as of September 30, 2026 and 2025, were not material. Profit and loss recognized at the commencement date and interest income during the three and nine months ended September 30, 2026 and 2025, were not material. We monitor customer purchases over the term of their arrangement to assess the realizability of our lease receivable assets. Impairments during the three and nine months ended September 30, 2026 and 2025, were not material.

Operating-type Reagent Rental Arrangements. Our reagent rental arrangements that do not effectively transfer control of instruments to our customers are classified as operating leases, and we recognize instrument revenue and costs ratably over the term of the arrangement. The cost of the instrument is capitalized within property and equipment. During the three and nine months ended September 30, 2026, we transferred instruments of $2.3 million and $5.8 million, respectively, compared to $1.8 million and $7.9 million during the three and nine months ended September 30, 2025, respectively, from inventory to property and equipment.

We estimate future revenue to be recognized related to our reagent rental arrangements of approximately $139.1 million, of which approximately 5%, 20%, 19%, 17%, and 39% are expected to be recognized during the remainder of 2026, and the full years 2027, 2028, 2029, and thereafter, respectively. These future revenues relate to performance obligations not yet satisfied for which customers have committed to future purchases, net of expected price adjustments, and as a result are lower than stated contractual commitments by our customers.

Deferred Extended Warranties and Post-Contract Support Revenue

On December 31, 2025, our deferred revenue related to extended warranties and post-contract support was $27.1 million, of which approximately $1.4 million and $19.7 million was recognized during the three and nine months ended September 30, 2026, respectively, compared to $1.3 million and $18.7 million during the three and nine months ended September 30, 2025, respectively. Furthermore, as a result of new arrangements, our deferred revenue related to extended warranties and post-contract support was $27.6 million at September 30, 2026. Deferred revenue related to extended warranties and post-contract support with an original duration of more than one year was $10.1 million at September 30, 2026, of which approximately 10%, 38%, 29%, 14%, and 9% are expected to be recognized during the remainder of 2026, and the full years 2027, 2028, 2029, and thereafter, respectively. We have determined these arrangements do not include a significant financing component. We do not disclose information about remaining performance obligations that are part of contracts with an original expected duration of one year or less, and we do not adjust for the effect of the financing components when the period between customer payment and revenue recognition is one year or less.

Costs to Obtain a Contract

On December 31, 2025, our deferred commission costs, included within other current and long-term assets, were $21.4 million, of which approximately $1.9 million and $5.9 million of commission expense was recognized during the three and nine months ended September 30, 2026, respectively, compared to $1.7 million and $5.3 million during the three and nine months ended September 30, 2025, respectively. Furthermore, as a result of commissions related to new extended warranties and SaaS subscriptions, net of subsequent recognition, our deferred commission costs were $20.9 million at September 30, 2026. Impairments of deferred commission costs during the three and nine months ended September 30, 2026 and 2025, were not material.

NOTE 4. ACQUISITIONS, ASSET PURCHASES AND INVESTMENTS

We believe that our acquisitions of businesses and other assets enhance our existing businesses by either expanding our geographic range, customer base, or existing product and service lines. From time to time, we acquire reference laboratories, radiology practices, and other businesses or assets that we account for as either asset purchases or business combinations, depending on facts and circumstances. We also may acquire noncontrolling minority interests in business entities, which we recognize as equity investments, and commercial rights to certain technology and intellectual property through licensing agreements.

Business Acquisition

On September 15, 2026, we acquired 100% of the shares of CoVetAI Inc. (“CoVet”), a provider of AI-native ambient listening and clinical workflow software for veterinary practices, for approximately $250 million, including an estimated contingent payment of $20 million, and various holdbacks of approximately $4 million. The acquisition expands our software offerings to support our customers with technology solutions that raise the standard of care for patients, improve practice efficiency, and enable more effective communication with pet owners.

We have not finalized the valuation of certain assets acquired, including identifiable intangible assets, due to the short period of time from the close of the acquisition to the reporting date. The purchase price allocation is provisional and subject to revision during the measurement period, which will not exceed one year from the date of acquisition, as additional information becomes available regarding valuation of intangibles, working capital adjustments, contingent consideration valuation, and tax-related matters. The primary areas of the purchase price allocation that are not yet finalized relate to the fair values of intangible assets related to technology and customer relationships. We estimate the preliminary fair values and the lives of the assets acquired and liabilities assumed as follows: approximately $12 million in technology-related intangibles with an expected life of three years; approximately $13 million in customer-relationship intangibles with an expected life of nine years; approximately $230 million in goodwill, representing the assembled workforce and synergies within our broader CAG portfolio; and approximately $5 million in net tangible liabilities assumed. The allocation of goodwill to reporting units within CAG is not complete. Goodwill related to this acquisition is not expected to be deductible for tax purposes.

Pro forma information has not been presented for this acquisition because such information is not material to the financial statements. The results of operations are included in our CAG segment since the acquisition date, and were not material to our CAG segment. Transactions recognized separately from the acquisition of assets and assumptions of liabilities include the replacement of unvested stock awards that were previously granted by CoVet, in the form of cash and stock awards of approximately $7 million, which will be recognized as compensation expense over a three-year period. The acquisition expenses, which were not significant, were recorded as general and administrative expenses. Refer to “Note 18. Fair Value Measurements” for a description of the contingent consideration.

Asset Purchase

During September 2025, we acquired a customer relationship intangible asset of a privately-owned reference laboratory in the U.S. for approximately $15.6 million, including an estimated contingent payment of $2.3 million at the time of acquisition. The customer relationship intangible has an estimated life of 10 years. The revenue associated with the acquired customer relationships has been included in our CAG segment since the acquisition date.

NOTE 5. SHARE-BASED COMPENSATION

The fair values of options, restricted stock units, deferred stock units, performance-based restricted stock units, and employee stock purchase rights awarded during the three and nine months ended September 30, 2026, were $3.7 million and $87.7 million, respectively (including replacement awards with a total fair value of $2.8 million that were issued in connection with the acquisition of CoVet), compared to $2.0 million and $70.2 million for the three and nine months ended September 30, 2025, respectively. The total unrecognized compensation expense, net of estimated forfeitures, for unvested share-based compensation awards outstanding as of September 30, 2026, was $90.7 million, which will be recognized over a weighted average period of approximately 1.5 years. During the three and nine months ended September 30, 2026, we recognized share-based compensation expenses of $16.2 million and $48.6 million, respectively, compared to $14.4 million and $43.9 million for the three and nine months ended September 30, 2025.

We determine the assumptions used in the valuation of option awards as of the date of grant. Differences in the expected stock price volatility, expected term, or risk-free interest rate may necessitate distinct valuation assumptions at those grant dates. As such, we may use different assumptions for options granted throughout the year. Option awards are granted with an exercise price equal to or greater than the closing market price of our common stock at the date of grant. We have never paid cash dividends on our common stock, and we have no intention to pay such a dividend at this time; therefore, we assume that no dividends will be paid over the expected terms of option awards.

NOTE 6. CREDIT LOSSES

We are exposed to credit losses primarily through our sales of products and services to our customers. We maintain allowances for credit losses for potentially uncollectible receivables. Additional allowances may be required if the financial condition of our customers was to deteriorate or a strengthening U.S. dollar impacts the ability of foreign customers to make payments to us for their U.S. dollar-denominated purchases. We monitor our ongoing credit exposure through active review of counterparty balances against contract terms and due dates, timely account reconciliations, dispute resolution, and payment confirmations. We may employ collection agencies and legal counsel to pursue recovery of defaulted receivables. Account balances are charged off against the allowance when we believe it is probable the receivable will not be recovered. We do not have any off-balance sheet credit exposure related to our customers.

Accounts Receivable

The allowance for credit losses associated with accounts receivable was $13.9 million and $11.3 million as of September 30, 2026, and December 31, 2025, respectively. The amount of accounts receivable reflected on the balance sheet is net of this allowance. As of September 30, 2026, approximately 87% of our accounts receivable had not yet reached the invoice due date, and approximately 13% were considered past due. As of December 31, 2025, approximately 87% of our accounts receivable had not yet reached the invoice due date, and approximately 13% were considered past due.

Contract Assets and Lease Receivables

The allowance for credit losses associated with contract assets and lease receivables was $9.6 million and $8.6 million as of September 30, 2026, and December 31, 2025, respectively. The assets reflected on the balance sheet are net of these allowances.

NOTE 7. INVENTORIES

Inventories are stated at the lower of cost (first-in, first-out) or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation, and factors in assumptions of future demand, market conditions, remaining shelf life, or product functionality.

The components of inventories were as follows:


(in thousands)	September 30, 2026		December 31, 2025

Raw materials	$	106,036	$	96,299
Work-in-process	35,862		32,588

NOTE 10. ACCOUNTS PAYABLE, ACCRUED LIABILITIES AND OTHER LONG-TERM LIABILITIES

Accounts Payable - Supplier Financing Program

We have an agreement with a third party to provide a supplier financing program, which facilitates participating suppliers’ ability to finance payment obligations from us with a designated third-party financial institution. Participating suppliers may, at their sole discretion, make offers to finance one or more of our payment obligations prior to their scheduled due dates at a discounted price. Our obligations to our suppliers, including amounts due and scheduled payment dates, are not impacted by suppliers’ decisions to finance amounts under these arrangements. The terms of payments are consistent with the terms of our trade payables. Activity related to the obligations is presented within operating activities on the unaudited condensed consolidated statements of cash flows.

The changes in our outstanding payment obligations under this arrangement, which are included in accounts payable on the unaudited condensed consolidated balance sheets, were as follows:


(in thousands)	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2026		2025		2026		2025

NOTE 11. DEBT

Credit Facility

As of September 30, 2026, we had $474.0 million in outstanding borrowings under our $1.25 billion five-year unsecured credit facility (the “Credit Facility”), of which $250.0 million is a three-year, unsecured term loan (the “Term Loan”), compared to $398.0 million outstanding under the Credit Facility, of which $250.0 million is the Term Loan, at December 31, 2025. The Credit Facility’s interest rate and commitment fee terms are unchanged from those described in our 2025 Annual Report.

The weighted average effective interest rate, excluding the impact of our interest rate swap (refer to “Note 19 - Hedging Instruments”), as of September 30, 2026, was 4.7%, compared to 5.3% as of December 31, 2025. At September 30, 2026, we had remaining borrowing availability of $773.2 million, net of $2.8 million of letters of credit primarily issued in connection with our workers’ compensation insurance policy.

Senior Notes

The following table describes our outstanding unsecured senior notes issued and sold in private placements (collectively, the “Senior Notes”) as of September 30, 2026:



(Principal Amounts in thousands)
Issue Date	Due Date	Series	Principal Amount		Coupon Rate		Senior Notes Agreement

2/12/2015	2/12/2027	2027 Series B Notes	$	75,000	3.72	%	MetLife 2014 Note Agreement

4/14/2020	4/14/2030	Prudential 2030 Series D Notes	$	75,000	2.50	%	Prudential 2015 Amended Agreement

We refer to the MetLife 2014 Agreement and the Prudential 2015 Amended Note Agreement, collectively, as the “Senior Note Agreements.”

On September 4, 2026, we repaid the aggregate principal amount of our 3.72% Senior Notes (“2026 Senior Notes”) for $75.0 million at maturity. There have been no other changes to the principal, maturity dates, interest rates, or prepayment terms of the Senior Notes as compared to those described in our 2025 Annual Report.

Covenants

Our Credit Facility and Senior Note Agreements contain affirmative, negative, and financial covenants and events of default, customary for agreements of this type, in each case as described in our 2025 Annual Report. The sole financial covenant under each of these agreements is a consolidated leverage ratio test (debt to Adjusted EBITDA), calculated in accordance with the terms of each of these agreements, not to exceed 3.5-to-1. As of September 30, 2026, we were in compliance with all covenants under the Credit Facility and the Senior Note Agreements.

NOTE 12. REPURCHASES OF COMMON STOCK

We primarily acquire shares of our common stock by repurchases in the open market. We also acquire shares that are surrendered by employees in payment for the statutory withholding taxes due on the vesting of restricted stock units and the settlement of deferred stock units, otherwise referred to herein as employee surrenders. We issue shares of treasury stock upon the vesting of certain restricted stock units and upon the exercise of certain stock options. The number of shares of treasury stock issued during the three and nine months ended September 30, 2026 and 2025, was not material. We have recognized approximately $— and $3.9 million in accrued liabilities related to the timing of settlements for share repurchases as of September 30, 2026 and December 31, 2025, respectively.

The cost of treasury stock includes a 1% excise tax on the value of shares repurchased in the open market, net of a reduction for eligible stock issuances, which is included in the cost of treasury stock acquired in open market repurchases. During the nine months ended September 30, 2026 and 2025, we incurred applicable excise taxes of $5.4 million and $7.2 million, respectively, and paid excise tax, net of refunds, during the nine months ended September 30, 2026 and 2025, of $6.8 million and $8.4 million, respectively.

The following table is a summary of our open market common stock repurchases, reported on a trade date basis, and shares acquired through employee surrenders:


(in thousands, except per share amounts)	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2026		2025		2026		2025

Average cost per share - total	$	563.01	$	587.52	$	588.62	$	475.76

NOTE 13. INCOME TAXES

Our effective income tax rates were 20.6% and 20.3% for the three and nine months ended September 30, 2026, respectively, compared to 20.4% and 20.2% for the three and nine months ended September 30, 2025, respectively.

Our current-period effective tax rate for the three months ended September 30, 2026, increased compared to the prior-year period, primarily due to lower tax benefits from share-based compensation and higher international taxes on foreign earnings. These unfavorable impacts were partially offset by the favorable comparative impact from a prior-year reduction in our U.S. tax benefit associated with Foreign-Derived Intangible Income (“FDII”) that resulted from the acceleration of research and development deductions permitted under changes in U.S. tax law that were enacted in July 2025, and by lower state income tax expense.

Our current-period effective tax rate for the nine months ended September 30, 2026, increased compared to the prior-year period primarily due to lower tax benefits from share-based compensation and from the resolution of international tax audits in the prior year. These unfavorable impacts were partially offset by the favorable comparative impact from a prior-year reduction in our U.S. tax benefit associated with FDII that resulted from the acceleration of research and development deductions permitted under changes in U.S. tax law that were enacted in July 2025.

The effective tax rates for the three and nine months ended September 30, 2026, were lower than the U.S. federal statutory tax rate of 21% primarily due to tax benefits from share-based compensation, partially offset by U.S. state taxes.

Cash paid for income taxes, net of refunds, during the nine months ended September 30, 2026 and 2025, were $166.2 million and $150.1 million, respectively.

NOTE 15. EARNINGS PER SHARE

Basic earnings per share is computed by dividing net income attributable to our stockholders by the weighted average number of shares of common stock and vested deferred stock units outstanding during the period. The computation of diluted earnings per share is similar to the computation of basic earnings per share, except that the denominator is increased for the assumed exercise of dilutive options, assumed issuance of unvested restricted stock units, and unvested deferred stock units using the treasury stock method unless the effect is anti-dilutive. The treasury stock method assumes that proceeds, including cash received from the exercise of employee stock options and the total unrecognized compensation expense for unvested share-based compensation awards, would be used to purchase our common stock at the average market price during the period. Vested deferred stock units outstanding are included in shares outstanding for basic and diluted earnings per share because the associated shares of our common stock are issuable for no cash consideration, the number of shares of our common stock to be issued is fixed, and issuance is not contingent. Refer to “Note 5. Share-Based Compensation” to the consolidated financial statements in our 2025 Annual Report for additional information regarding deferred stock units.

The following is a reconciliation of weighted average shares outstanding for basic and diluted earnings per share:


(in thousands)	For the Three Months Ended September 30,		For the Nine Months Ended September 30,
	2026	2025	2026	2025

Shares outstanding for basic earnings per share	78,825	80,096	79,139	80,605

Shares outstanding for diluted earnings per share:
Shares outstanding for basic earnings per share	78,825	80,096	79,139	80,605
Dilutive effect of share-based payment awards	224	579	373	602
Total shares outstanding for basic and diluted earnings per share	79,049	80,675	79,512	81,207

Certain awards and options to acquire shares have been excluded from the calculation of weighted average shares outstanding for diluted earnings per share because they were anti-dilutive. The following table presents information concerning those anti-dilutive awards and options:


(in thousands)	For the Three Months Ended September 30,		For the Nine Months Ended September 30,

Weighted average number of shares underlying anti-dilutive options	325	236	302	551

NOTE 16. COMMITMENTS, CONTINGENCIES AND GUARANTEES

Commitments

Refer to “Note 8. Lease Commitments” for more information regarding our lease commitments.

Contingencies

We are subject to claims that may arise in the ordinary course of business, including with respect to actual and threatened litigation and other matters. We accrue for loss contingencies when it is probable that future expenditures will be made, and such expenditures can be reasonably estimated. However, the results of legal actions cannot be predicted with certainty, and therefore our actual losses with respect to these contingencies could exceed our accruals. Our accruals with respect to actual and threatened litigation were not material as of September 30, 2026.

We were a defendant in a litigation involving an alleged breach of contract for underpayment of royalty payments made from 2004 through 2017 under an expired patent license agreement. In April 2025, at the conclusion of the proceedings at the trial and appellate courts, we paid a judgment in the amount of approximately $80.0 million, which was accrued in prior years, and the plaintiff executed a satisfaction and release of judgment, which was filed with the trial court, concluding this matter.

From time to time, we receive notices alleging that our products infringe third-party proprietary rights, although we are not aware of any pending litigation with respect to such claims. Patent litigation is frequently complex and expensive, and the outcome of patent litigation can be difficult to predict. There can be no assurance that we will prevail in any infringement proceedings that may be commenced against us. If we lose any such litigation, we may be stopped from selling certain products and/or we may be required to pay damages as a result of the litigation.

Guarantees

We enter into agreements with third parties in the ordinary course of business under which we are obligated to indemnify such third parties for and against various risks and losses. The precise terms of such indemnities vary with the nature of the agreement. In many cases, we limit the maximum amount of our indemnification obligations, but in some cases, those obligations may be theoretically unlimited. We have not incurred material expenses in discharging any of these indemnification obligations and, based on our analysis of the nature of the risks involved, we believe that the fair value of potential indemnification under these agreements is minimal. Accordingly, we have recorded no liabilities for these obligations as of September 30, 2026, and December 31, 2025.

When acquiring a business, we sometimes assume liability for certain events or occurrences that took place prior to the date of acquisition. As of September 30, 2026, and December 31, 2025, we have not recorded any material pre-acquisition liabilities.

NOTE 17. SEGMENT REPORTING

We operate primarily through three reportable segments: Companion Animal Group (“CAG”), Water quality products (“Water”), and Livestock, Poultry and Dairy (“LPD”). CAG provides diagnostics and information management products and services for the companion animal veterinary industry and the biomedical research community. Water provides testing solutions and related instrumentation for the detection and quantification of various microbiological parameters in water. LPD provides diagnostic tests, services, and related instrumentation that are used to manage the health status of livestock and poultry, to improve producer efficiency, and to measure the quality and safety of milk. Our Other non-reportable segment results combine and present our human medical diagnostic business with our out-licensing arrangement because they do not meet the quantitative or qualitative thresholds for reportable segments.

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision-maker (“CODM”) in assessing performance. The CODM, our president and Chief Executive Officer, evaluates the performance of operating segments based on revenue and gross profit. Our CODM reviews the budget and actual financial results of the operating segments, decides how to allocate resources to meet our strategic priorities, and meets with operating segment leaders on a periodic basis to determine the allocation of resources.

The accounting principles used in the preparation of the segment information are the same as those used for the consolidated financial statements. Intersegment revenues, which are not included in the tables below, were not material for the three and nine months ended September 30, 2026 and 2025. Refer to “Note 3. Revenue” for a summary of disaggregated revenue by segment and by major product and service category for the three and nine months ended September 30, 2026 and 2025. Assets are not allocated to segments for internal reporting purposes and are not included in the review performed by the CODM for purposes of assessing segment performance and allocation of resources. Certain corporate expenses are allocated to the segments, including depreciation and amortization. Foreign currency transaction gains and losses for all operating segments are reported within Other and are reconciled in the tables below.

The following tables are a summary of reportable segment performance with Other to reconcile to our consolidated results for the three months ended September 30, 2026 and 2025:

NOTE 18. FAIR VALUE MEASUREMENTS

U.S. GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. U.S. GAAP requires an entity to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs when measuring fair value.

We have certain financial assets and liabilities that are measured at fair value on a recurring basis, certain nonfinancial assets and liabilities that may be measured at fair value on a non-recurring basis, and certain financial assets and liabilities that are not measured at fair value in our unaudited condensed consolidated balance sheets, but for which we disclose the fair value. The fair value disclosures of these assets and liabilities are based on a three-level hierarchy, which is defined as follows:


Level 1						Quoted prices in active markets for identical assets or liabilities that the entity can access at the measurement date.
Level 2						Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3						Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. We did not have any transfers between Level 1 and Level 2, or transfers in or out of Level 3, of the fair value hierarchy for the periods presented.

Our cross currency swap contracts are measured at fair value on a recurring basis in our accompanying unaudited condensed consolidated balance sheets and are classified as derivative instruments. We measure the fair value of our cross currency swap contracts using prevailing market conditions as of the close of business on each balance sheet date. The product of this calculation is then adjusted for counterparty risk.

Our foreign currency exchange contracts are measured at fair value on a recurring basis in our accompanying unaudited condensed consolidated balance sheets and are classified as derivative instruments. We measure the fair value of our foreign currency exchange contracts using an income approach, based on prevailing market forward exchange rates less the contract rate multiplied by the notional amount. The product of this calculation is then adjusted for counterparty risk.

Our interest rate swap contracts are measured at fair value on a recurring basis in our accompanying unaudited condensed consolidated balance sheets and are classified as derivative instruments. We measure the fair value of our interest rate swap contracts using current market interest rates for debt issues with similar remaining years to maturity, adjusted for applicable credit risk.

The amounts outstanding under our unsecured Credit Facility and our Senior Notes are measured at carrying value in our unaudited condensed consolidated balance sheets though we disclose the fair value of these financial instruments. We determine the fair value of the amount outstanding under our Credit Facility and Senior Notes using an income approach, utilizing a discounted cash flow analysis based on current market interest rates for debt issues with similar remaining years to maturity, adjusted for applicable credit risk. Our Credit Facility and Senior Notes are valued using Level 2 inputs. The estimated fair value of our Credit Facility approximates its carrying value. As of September 30, 2026, the estimated fair value and carrying value of our Senior Notes were $355.1 million and $375.0 million, respectively. As of December 31, 2025, the estimated fair value and carrying value of our Senior Notes were $444.8 million and $450.0 million, respectively.

The following tables set forth our assets and liabilities that were measured at fair value on a recurring basis by level within the fair value hierarchy:

The estimated fair values of certain financial instruments, including cash and cash equivalents, accounts receivable, and accounts payable, approximate their respective carrying values due to their short maturity.

Investment in Limited Partnership Fund

We hold an investment in a limited partnership fund (the “Fund”) that invests in growth and early-stage businesses engaged in pet product and service businesses. We believe that fair value best reflects the economics of the underlying transaction. We estimate the fair value of our investment in the Fund under the Net Asset Value (“NAV”) practical expedient based on the most recent NAV reported by the general partner, adjusted for subsequent contributions, distributions, and significant events. Investments measured using the NAV practical expedient are not classified in the fair value hierarchy. The fair value of the investment was $4.0 million at September 30, 2026, compared to $1.8 million at December 31, 2025.

We recognize changes in the fair value of our investment in net income as non-operating gains (losses) on equity investment because the investment is not a core business activity. We realize proceeds from the Fund’s distributions when its underlying investments are sold, with liquidation of the Fund’s assets expected over a period of time of up to approximately 13 years from inception in 2024. We cannot redeem our interests until the Fund’s dissolution, our interest is non-transferable without general partner consent, and no public market exists.

During the three months ended September 30, 2026, we received proceeds distributed by the Fund of $4.1 million. Our unfunded commitment was approximately $2.6 million at September 30, 2026.

Contingent Consideration

We have classified our liabilities for contingent consideration related to acquisitions within Level 3 of the fair value hierarchy because the fair value is determined using significant unobservable inputs, which relates to the achievements of future revenue. The contingent consideration is included within other long-term liabilities.

We record changes in the estimated fair value of contingent consideration at each reporting date in the consolidated statements of income within general and administrative expense. Changes in contingent consideration liabilities are measured at fair value on a recurring basis using unobservable inputs (Level 3).

During the third quarter of 2026, we acquired CoVet. We estimate that the acquisition-date fair value of contingent consideration was $20.2 million, which we determined using a probability-weighted expected cash flow analysis of future revenue. The undiscounted amount that could be paid ranges from zero to a maximum of $47.5 million, based on annual revenue targets achieved during the years ended December 31, 2027, 2028, and 2029.

NOTE 19. HEDGING INSTRUMENTS

Disclosure within this note is presented to provide transparency about how and why we use derivative and non-derivative instruments (collectively “hedging instruments”), how the hedging instruments and related hedged items are accounted for, and how the hedging instruments and related hedged items affect our financial position, results of operations, and cash flows.

We recognize all hedging instrument assets and liabilities on the balance sheet at fair value at the balance sheet date. Hedging instruments that do not qualify for hedge accounting treatment are recorded at fair value through earnings. To qualify for hedge accounting treatment, hedging instruments must be highly effective in offsetting changes to expected future cash flows or fair value on hedged transactions. If the hedging instrument qualifies for hedge accounting, changes in the fair value of the hedging instrument from the effective portion of the hedge are deferred in AOCI, net of tax, and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. We immediately record in earnings the extent to which a hedging instrument is not effective in achieving offsetting changes in fair value. We de-designate hedging instruments from hedge accounting when the likelihood of the hedged transaction occurring becomes less than probable. For de-designated hedging instruments, the gain or loss from the time of de-designation through maturity of the instrument is recognized in earnings. Any gain or loss in AOCI at the time of de-designation is reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Refer to “Note 14. Accumulated Other Comprehensive Income” for further information regarding the effect of hedging instruments on the unaudited condensed consolidated statements of income for the three and nine months ended September 30, 2026 and 2025.

We enter into master netting arrangements with the counterparties to our derivative transactions, which permit certain outstanding receivables and payables to be offset in the event of default. Our derivative contracts do not require either party to post cash collateral. We elect to present our derivative assets and liabilities in the accompanying unaudited condensed consolidated balance sheets on a gross basis. All cash flows related to our foreign currency exchange contracts are classified as operating cash flows, which is consistent with the cash flow treatment of the underlying items being hedged.

Our subsidiaries enter into foreign currency exchange contracts to reduce the exchange risk associated with their forecasted intercompany inventory purchases and sales for the next year. We may also enter into other foreign currency exchange contracts, cross currency swaps, or foreign-denominated debt issuances to reduce the impact of foreign currency fluctuations associated with specific balance sheet exposures, including net investments in certain foreign subsidiaries.

The primary purpose of our foreign currency hedging activities is to protect against the volatility associated with foreign currency transactions, including transactions denominated in euro, British pound, Japanese yen, Canadian dollar, and Australian dollar. We also utilize natural hedges to mitigate our transaction and commitment exposures. Our corporate policy prescribes the range of allowable hedging activity. We enter into foreign currency exchange contracts with large, well-capitalized multinational financial institutions, and we do not hold or engage in transactions involving derivative instruments for purposes other than risk management. Our accounting policies for these contracts are based on our designation of such instruments as hedging transactions.

Cash Flow Hedges

We have designated our foreign currency exchange contracts and our interest rate swaps as cash flow hedges because these derivative instruments reduce our exposure to variability in the cash flows of forecasted transactions attributable to foreign currency exchange and to interest rates on variable interest obligations of our Term Loan. Unless noted otherwise, we have also designated our derivative instruments as qualifying for hedge accounting treatment.

We did not de-designate any instruments from hedge accounting treatment during the nine months ended September 30, 2026, or 2025. Gains and losses related to hedge ineffectiveness recognized in earnings during the nine months ended September 30, 2026 and 2025, were not material. As of September 30, 2026, the estimated amount of gains, net of tax, from our foreign exchange contracts which are expected to be reclassified out of AOCI and into earnings within the next twelve months is $6.1 million if exchange rates do not fluctuate from the levels as of September 30, 2026. As of September 30, 2026, the estimated amount of gains, net of tax, from our interest rate swap contract which are expected to be reclassified out of AOCI and into earnings within the next twelve months is $1.9 million if interest rates do not fluctuate from the levels as of September 30, 2026.

Interest Rate Swaps: We have entered into an interest rate swap contract to reduce the effect of variable interest obligations of our Term Loan. Beginning in November 2025 through November 2028, the variable interest rate associated with the $250.0 million of borrowings outstanding under our Credit Facility became effectively fixed at 3.4% plus the applicable credit spread. We previously held an interest rate swap to reduce the effect of variable interest obligations of our Term Loan for the period from March 2023 through October 2025, associated with the $250.0 million of borrowings under our Credit Facility, which effectively fixed the interest rate at 3.9% plus the applicable credit spread.

Foreign Currency Exchange Contracts: We target to hedge approximately 75% to 85% of the estimated exposure from intercompany product purchases and sales denominated in the euro, British pound, Japanese yen, Canadian dollar, and Australian dollar. We have additional unhedged foreign currency exposures related to intercompany foreign transactions where it is not practical to hedge. We primarily utilize foreign currency exchange contracts with durations of less than 24 months. Quarterly, we enter into contracts to hedge incremental portions of anticipated foreign currency transactions for the current and following year. As a result, our risk with respect to foreign currency exchange rate fluctuations and the notional value of foreign currency exchange contracts may vary throughout the year. The U.S. dollar is the currency purchased or sold in all of our foreign currency exchange contracts. The notional amount of foreign currency exchange contracts to hedge forecasted intercompany inventory purchases and sales totaled $503.7 million and $397.6 million as of September 30, 2026, and December 31, 2025, respectively.

The following table presents the effects of cash flow hedge accounting on our unaudited condensed consolidated statements of income and comprehensive income, and provides information regarding the location and amounts of pretax gains or losses of derivatives:

Net Investment Hedges, Euro-Denominated Notes

In June 2015, we issued and sold through a private placement an aggregate principal amount of €88.9 million in euro-denominated 1.785% Series C Senior Notes that were due June 18, 2025. We designated these euro-denominated notes as a hedge of our euro net investment in certain foreign subsidiaries to reduce the volatility caused by changes in foreign currency exchange rates in the euro relative to the U.S. dollar. As a result of this designation, gains and losses from the change in the translated U.S. dollar value of these euro-denominated notes were recorded in AOCI rather than earnings. During the nine months ended September 30, 2025, we recorded losses of $9.0 million, net of tax, within AOCI as a result of these net investment hedges. At the maturity of the 1.785% Series C Senior Notes in June 2025, we paid the notional amount of €88.9 million, equivalent to $103.4 million at the date of payment. Refer to “Note 13. Debt” to the consolidated financial statements included in our 2025 Annual Report for further information regarding these euro-denominated notes.

Net Investment Hedges, Cross Currency Swaps

We have entered into cross currency swap contracts as hedges of our net investments in certain foreign subsidiaries to reduce the volatility caused by changes in foreign currency exchange rates relative to the U.S. dollar. The cross currency swaps outstanding as of September 30, 2026, have maturity dates beginning on March 31, 2028, through September 11, 2032.

The following table presents the outstanding cross currency swaps notional amounts that will be delivered to and received from the counterparties at maturity:



(in thousands)
Maturity Date	Notional Amount to be Delivered at Maturity		Notional Amount to be Received at Maturity

3/31/2028	€	35,000	$	37,755
6/30/2028	€	90,000	$	98,217
7/17/2028	€	76,000	$	88,113
7/31/2028	€	39,000	$	45,735
6/29/2029	€	20,000	$	21,268
9/11/2032	¥	3,683,750	$	25,000

The changes in fair value of the cross currency swap contracts are recorded in AOCI and will be reclassified to earnings when the foreign subsidiaries are sold or substantially liquidated or all or a portion of the hedge no longer qualifies for hedge accounting treatment. During the three and nine months ended September 30, 2026, we recorded gains of $1.0 million and $6.3 million, net of tax, within AOCI as a result of these net investment hedges, compared to gains of $1.1 million and losses of $13.0 million during the three and nine months ended September 30, 2025, respectively. We receive quarterly interest payments from the counterparties based on a fixed interest rate until maturity of the cross currency swaps. This interest rate component is excluded from the assessment of hedge effectiveness and is recognized as a reduction to interest expense over the life of the hedge instrument. We recognized approximately $1.0 million and $3.1 million related to the excluded component as a reduction of interest expense for the three and nine months ended September 30, 2026, respectively, and $0.8 million and $1.6 million for the three and nine months ended September 30, 2025, respectively.

While we may elect to update forward-looking statements at some point in the future, we specifically disclaim any obligation to do so, even if our estimates or expectations change.

You should read the following discussion and analysis in conjunction with our 2025 Annual Report that includes additional information about us, our results of operations, our financial position, and our cash flows, and with our unaudited condensed consolidated financial statements and related notes included in “Part I. Item 1. Financial Statements” of this Quarterly Report on Form 10-Q.

Our fiscal quarter ended on September 30. Unless otherwise stated, the analysis and discussion of our financial condition and results of operations below, including references to growth and organic growth and increases and decreases, are being compared to the equivalent prior-year periods.

Business Overview

We develop, manufacture, and distribute products and provide services primarily for the companion animal veterinary, livestock, poultry and dairy, and water testing sectors. We also manufacture and sell human medical point-of-care diagnostic products. Our primary products and services are:

•Point-of-care veterinary diagnostic products, comprised of instruments, consumables, and rapid assay test kits;

•Veterinary reference laboratory diagnostic and consulting services;

•Practice management systems, software and diagnostic imaging systems and services used by veterinarians;

•Health monitoring, biological materials testing, laboratory diagnostic instruments, and services used by the biomedical research community;

•Diagnostic and health-monitoring products for livestock, poultry, and dairy; and

•Products that test water for certain microbiological contaminants.

Description of Operating Segments. We operate primarily through three reportable segments: Companion Animal Group (“CAG”), Water quality products (“Water”), and Livestock, Poultry and Dairy (“LPD”). CAG provides diagnostics and information management products and services for the companion animal veterinary industry and the biomedical research community. Water provides testing solutions and related instrumentation for the detection and quantification of various microbiological parameters in water. LPD provides diagnostic tests, services, and related instrumentation that are used to manage the health status of livestock and poultry, to improve producer efficiency, and to measure the quality and safety of milk. Our Other non-reportable segment results combine and present our human medical diagnostic business with our out-licensing arrangement because they do not meet the quantitative or qualitative thresholds for reportable segments.

Global Conflicts. The current macroeconomic environment and ongoing global conflicts, including hostilities in the Middle East, have contributed to volatility in global energy markets and higher fuel prices, and could further disrupt transportation networks and supply chains, particularly in the Asia Pacific and European regions. Higher fuel prices increase our freight and distribution costs. These conditions may also cause other impacts on our operating costs and consumer availability and demand for our products and services, and contribute to foreign currency exchange rate volatility.

Currency Impact. Refer to “Part I, Item 3. Quantitative and Qualitative Disclosures about Market Risk” included in this Quarterly Report on Form 10-Q for additional information regarding the impact of foreign currency exchange rates.

Other Items. Refer to “Part I, Item 1. Intellectual Property, Including Patents and Licenses” and “Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our 2025 Annual Report for additional information regarding trends in companion animal healthcare, supply chain and logistics challenges, economic conditions, changes in tariff and trade policies, distributor purchasing and inventories, and patent expiration.

Critical Accounting Estimates and Assumptions

The discussion and analysis of our financial condition and results of operations is based upon our unaudited condensed consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, and expenses, and related disclosures of contingent assets and liabilities. We evaluate our estimates on an ongoing basis. We base our estimates on historical experience and on various assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. The critical accounting policies and the significant judgments and estimates used in the preparation of our unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2026, are consistent with those discussed in our 2025 Annual Report in the section under the heading “Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Estimates and Assumptions.”

Recent Accounting Pronouncements

For more information regarding the impact that recent accounting standards and amendments will have on our consolidated financial statements, refer to “Note 2. Accounting Policies” to the unaudited condensed consolidated financial statements in “Part I. Item 1. Financial Statements” of this Quarterly Report on Form 10-Q.

Non-GAAP Financial Measures

The following revenue analysis and discussion includes organic revenue growth, and references in this analysis and discussion to “revenue,” “revenues,” or “revenue growth” apply equally to revenue growth reported in accordance with U.S. GAAP and to “organic revenue growth.” Organic revenue growth is a non-GAAP financial measure and represents the percentage change in revenue during the three and nine months ended September 30, 2026, compared to the same period for the prior year, net of the effect of changes in foreign currency exchange rates, certain business acquisitions, and divestitures. Organic revenue growth should be considered in addition to, and not as a replacement for, or as a superior measure to, revenue growth reported in accordance with U.S. GAAP, and may not be comparable to similarly titled measures reported by other companies. 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.

We exclude from organic revenue growth the effect of changes in foreign currency exchange rates because changes in foreign currency exchange rates are not under management’s control, are subject to volatility, and can obscure underlying business trends. We calculate the impact on revenue resulting from changes in foreign currency exchange rates by applying the

difference between the weighted average exchange rates during the current period and the comparable prior year period to foreign currency denominated revenue for the prior year period.

We also exclude from organic revenue growth the effect of certain business acquisitions and divestitures because the nature, size, and number of these transactions can vary dramatically from period to period, and because they either require or generate cash as an inherent consequence of the transaction, and therefore can also obscure underlying business and operating trends. We consider acquisitions to be a business when all three elements of inputs, processes, and outputs are present, consistent with ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business.” We do not consider acquired assets to be a business if substantially all the fair value of the assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. A typical acquisition that we do not consider a business is a customer relationship asset acquisition, which does not have all elements necessary to operate a business, such as employees or infrastructure. Revenue from these customers acquired is included in organic revenue growth because we believe the efforts required to convert and retain these acquired customers are similar in nature to our efforts to obtain and retain our existing customer base.

Segment Income from Operations. We report segment income from operations in our discussion of the results of the operations of our segments below. Segment income from operations is a non-GAAP financial measure that adjusts for the impact of foreign currency transaction gains and losses and should be considered in addition to, and not as a replacement for, or superior measure to, income from operations. We exclude foreign currency transaction gains and losses for each reportable segment (CAG, Water, and LPD) from segment income from operations and report the full amount of foreign currency transaction gains and losses in Other. We believe that reporting segment income from operations provides supplemental analysis to help investors further evaluate each reportable segment’s business performance by excluding foreign currency transaction gains and losses, which are centrally managed by our corporate treasury function and which we do not consider relevant for assessing the results of each reportable segment’s operations.

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

(1)Reported revenue growth and organic revenue growth may not recalculate due to rounding.

Total Company Revenue. The increase in revenue primarily reflected growth in CAG Diagnostics recurring revenue, including benefits from higher volumes and higher realized prices. Volume growth was supported by high customer retention rates with increased testing by existing customers, including our expanded menu of available tests, as well as new customer additions. Instrument revenue was relatively constant primarily due to higher instrument placements offset with lower price realization. Higher volumes and realized prices in recurring veterinary software subscriptions, services, and diagnostic imaging also contributed to revenue growth. Revenue growth in our Water and LPD businesses were primarily due to higher realized prices and volumes. The impact on revenue from our acquisition of CoVet on September 15, 2026, was immaterial for the period. Changes in foreign currency exchange rates did not have a significant impact on revenue growth.

Gross Profit. Gross profit increased due to higher revenue and a 110 basis point increase in the gross profit margin. The increase in the gross profit margin reflected benefits from higher IDEXX VetLab consumable volume growth and the business mix impact associated with proportionally higher revenue, operational productivity improvements, and net price realization which offset inflationary costs. Changes in foreign currency exchange rates increased the gross profit margin by approximately 20 basis points, including the impact of hedge gains during the current period compared to hedge losses in the prior period.

Operating Expenses. Sales and marketing expense increased primarily due to higher personnel-related costs, including costs to support our commercial expansion, and higher travel expenses. General and administrative expense increased primarily due to higher consulting and professional services fees, higher compensation and benefits expenses, and higher depreciation and amortization related to technology and infrastructure investments. Research and development expense increased primarily due to higher personnel-related and project costs. Changes in foreign currency exchange rates decreased operating expense growth by less than 1%.

CAG Diagnostics Recurring Revenue. The increase in CAG Diagnostics recurring revenue was primarily due to higher sales volumes of IDEXX VetLab consumables and reference laboratory testing, as well as higher realized prices.

The increase in IDEXX VetLab consumables revenue was primarily due to higher volumes and higher realized prices. Volume gains were supported by increases in testing across major regions, reflecting growth in testing by existing customers, including sales of our expanded menu of available tests, and the benefits from 11% growth in our installed base of premium instruments. Changes in foreign currency exchange rates did not have a significant impact on revenue growth.

Rapid assay revenue increased from higher realized prices, largely offset by lower volumes primarily due to reduced point-of-care vector-borne disease testing volumes, and a shift of customers’ pancreatic lipase testing to our CatalystTM instrument platform. Changes in foreign currency exchange rates did not have a significant impact on revenue growth.

The increase in reference laboratory diagnostic and consulting services revenue was due to higher testing volumes across all major regions and higher realized prices. Volume growth was supported by increased testing by existing and new customers, including sales of our expanded menu of tests. Changes in foreign currency exchange rates did not have a significant impact on revenue growth.

CAG Diagnostics Capital – Instrument Revenue. Instrument revenue was relatively constant compared to the prior period with higher instrument placements, primarily from higher placements of our SediVue DxTM and IDEXX inVue DxTM Analyzers, offset by lower price realization due to program effects on pricing. Changes in foreign currency exchange rates did not have a significant impact on revenue growth.

system sales. The impact on revenue from our acquisition of CoVet on September 15, 2026, was immaterial for the period. Changes in foreign currency exchange rates did not have a significant impact on revenue growth.

Segment income from operations	$	1,899	5.5	%	$	471	1.4	%	$	1,428	303.2	%

Revenue. The increase in revenue was primarily due to higher realized prices and increases in test volumes, particularly in the Americas. The increase in volumes was largely attributable to expanded testing and new customers, partially offset by declines in swine testing in Asia. Changes in foreign currency exchange rates decreased revenue growth by 0.4%.

Gross Profit. The increase in gross profit was primarily due to higher revenue and a 560 basis point increase in the gross profit margin. The increase in the gross profit margin was primarily due to lower per-unit costs and higher realized prices, which offset inflationary costs and higher depreciation expense. Changes in foreign currency exchange rates increased the gross profit margin by approximately 200 basis points, including the impact of hedge gains during the current period compared to hedge losses in the prior period.

Segment Operating Expenses. Sales and marketing expense increased primarily due to higher travel costs, partially offset by lower personnel-related costs. General and administrative expense increased primarily due to project-related consulting costs and higher personnel-related costs. Research and development expense increased primarily due to higher consulting costs. Changes in foreign currency exchange rates did not have a significant impact on operating expenses.

Non-Operating Items

Interest Expense and Income. Interest expense was $7.5 million for the three months ended September 30, 2026, compared to $10.7 million for the same period during the prior year primarily due to lower average debt levels. Interest income was $1.0 million and $0.6 million for the three months ended September 30, 2026, and September 30, 2025, respectively.

Gain (Loss) on Equity Investments. For the three months ended September 30, 2026, we recognized realized and unrealized gains on an equity investment of $3.5 million.

Provision for Income Taxes. Our effective income tax rates were 20.6% and 20.4% for the three months ended September 30, 2026, and September 30, 2025, respectively. The increase, compared to the prior period, was primarily due to lower tax benefits from share-based compensation and higher international taxes on foreign earnings. These unfavorable impacts were partially offset by the favorable comparative impact from a prior-year reduction in our U.S. tax benefit associated with FDII that resulted from the acceleration of research and development deductions permitted under changes in U.S. tax law that were enacted in July 2025, and by lower state income tax expense.

We anticipate reductions in share-based compensation tax benefits during the three months ending December 31, 2026, compared to the same period in the prior year, which increases our future effective tax rate. The anticipated reduction in these future tax benefits is due to the elimination of the exception for certain compensation deduction limits as a result of the Tax Cuts and Jobs Act of 2017.

Segment income from operations	$	5,600	5.5	%	$	91	0.1	%	$	5,509	6,053.8	%

Revenue. The increase in revenue was primarily due to higher test volumes, particularly in Europe and the Americas, and higher realized prices. The increase in volumes was largely attributable to new customers and favorable timing impacts in Europe due to changes in customer ordering patterns compared to the same period during the prior year. Changes in foreign currency exchange rates increased revenue growth by 2.3%.

Gross Profit. The increase in gross profit was primarily due to higher revenue and a 460 basis point increase in the gross profit margin. The increase in the gross profit margin was primarily due to lower per-unit costs from higher sales volumes, and higher realized prices, which offset inflationary costs and higher depreciation expense. Changes in foreign currency exchange rates increased the gross profit margin by approximately 80 basis points, including the impact of hedge gains during the current period compared to hedge losses in the prior period.

Segment Operating Expenses. Sales and marketing expense increased primarily due to higher travel costs. General and administrative expense increased primarily due to project-related consulting costs and higher personnel-related costs. Research and development expense increased primarily due to higher consulting costs. Changes in foreign currency exchange rates increased operating expense growth by approximately 1%.

Non-Operating Items

Interest Expense and Income. Interest expense was $25.4 million for the nine months ended September 30, 2026, compared to $29.6 million for the same period during the prior year primarily due to lower average debt levels and lower average interest rates. Interest income was $2.2 million for the nine months ended September 30, 2026, compared to $2.4 million for the same period during the prior year.

Gain (Loss) on Equity Investments. For the nine months ended September 30, 2026, we recognized realized and unrealized gains on an equity investment of $4.7 million.

Provision for Income Taxes. Our effective income tax rates were 20.3% and 20.2% for the nine months ended September 30, 2026, and September 30, 2025, respectively. The increase, compared with the prior-year period, was primarily due to lower tax benefits from share-based compensation and from the resolution of international tax audits in the prior year. These unfavorable impacts were partially offset by the favorable comparative impact from a prior-year reduction in our U.S. tax benefit associated with FDII that resulted from the acceleration of research and development deductions permitted under changes in U.S. tax law that were enacted in July 2025.

We anticipate reductions in share-based compensation tax benefits during the three months ending December 31, 2026, compared to the same period in the prior year, which increases our effective tax rate in 2026. The anticipated reduction in these future tax benefits is due to the elimination of the exception for certain compensation deduction limits as a result of the Tax Cuts and Jobs Act of 2017.

Liquidity and Capital Resources

We fund the capital needs of our business through cash on hand, funds generated from operations, proceeds from long-term senior note financings, and amounts available under our Credit Facility. We generate cash primarily through the payments made by customers for our companion animal, livestock, poultry, dairy, and water products and services, consulting services, and other various systems and services. Our cash disbursements are primarily related to compensation and benefits for our employees, inventory and supplies, repurchase of our common stock, taxes, research and development, capital expenditures, rents, occupancy-related charges, interest expense, and business acquisitions. Working capital totaled $235.8 million as of September 30, 2026, compared to $265.0 million as of December 31, 2025. The change in working capital is primarily due to higher current borrowings outstanding on our Credit Facility, partially offset by higher accounts receivable. As of September 30, 2026, we had $197.5 million of cash and cash equivalents, compared to $180.1 million as of December 31, 2025. As of September 30, 2026, we had a remaining borrowing availability of $773.2 million under our $1.25 billion Credit Facility, with $474.0 million in outstanding borrowings under our Credit Facility, and an option for the Company to incur incremental revolving credit commitments and/or term loans in the aggregate principal amount of up to $250.0 million. As of December 31, 2025, we had $398.0 million in outstanding borrowings under our Credit Facility. The general availability of funds under our Credit Facility is reduced by $2.8 million for outstanding letters of credit. We believe that, if necessary, we could obtain additional borrowings to fund our growth objectives. We further believe that current cash and cash equivalents, funds generated from operations, and committed borrowing availability will be sufficient to fund our operations, capital purchase requirements, and anticipated growth needs for the next twelve months. We believe that these resources, coupled with our ability, as needed, to incur incremental revolving credit commitments and/or term loans under our Credit Facility and otherwise obtain additional financing, will also be sufficient to fund our business as currently conducted for the foreseeable future. We may enter into new financing arrangements or refinance or retire existing debt in the future depending on market conditions. Should we require more capital in the U.S. than is generated by our operations, for example to fund significant discretionary activities, we could elect to raise capital in the U.S. through the incurrence of debt or equity issuances, which we may not be able to complete on favorable terms or at all. In addition, these alternatives could result in increased interest expense or other dilution of our earnings.

We manage our worldwide cash requirements considering available funds among all of our subsidiaries. Our foreign cash and cash equivalents are generally available without restrictions to fund ordinary business operations outside the U.S.

The following table presents cash, cash equivalents, and marketable securities held domestically and by our foreign subsidiaries:


(in thousands)	September 30, 2026		December 31, 2025

U.S.	$	14,113	$	1,606
Foreign	183,423		178,464
Total cash and cash equivalents	$	197,536	$	180,070

Total cash and cash equivalents held in U.S. dollars by our foreign subsidiaries	$	23,259	$	24,571

As of September 30, 2026, and December 31, 2025, more than 99% of the cash and cash equivalents were held as bank deposits at a diversified group of institutions, primarily systemically important banks. Cash and cash equivalents as of September 30, 2026, included approximately $0.9 million in cash denominated in non-U.S. currencies held in a country with currency control restrictions, which limit our ability to transfer funds outside of the country in which they are held without incurring costs. The currency control restricted cash is generally available for use within the country where it is held.

The following table presents additional key information concerning working capital:


	For the Three Months Ended
	September 30, 2026	June 30, 2026	March 31, 2026	December 31, 2025	September 30, 2025

Days sales outstanding (1)	46.7	46.2	46.2	46.8	46.5
Inventory turns (2)	1.5	1.4	1.4	1.6	1.5

(1) Days sales outstanding represents the average of the accounts receivable balances at the beginning and end of each quarter divided by revenue for that quarter, the result of which is then multiplied by 91.25 days.

(2) Inventory turns are calculated as the ratio of our inventory-related cost of revenue for the quarter multiplied by four, divided by the average inventory balances at the beginning and end of each quarter.

Sources and Uses of Cash

The following table presents cash provided (used):


	For the Nine Months Ended September 30,
(in thousands)	2026		2025		Change

Net cash provided by operating activities	$	1,063,127	$	826,045	$	237,082
Net cash used by investing activities	(307,140)		(108,109)		(199,031)
Net cash used by financing activities	(737,466)		(809,262)		71,796
Net effect of changes in exchange rates on cash	(1,055)		11,226		(12,281)
Net change in cash and cash equivalents	$	17,466	$	(80,100)	$	97,566

Operating Activities. Net cash provided by operating activities during the nine months ended September 30, 2026, was $1,063.1 million, which was a net increase in operating cash flows of $237.1 million, compared to the same period during the prior year. Cash was provided from net income of $934.0 million, adjusted for net non-cash items of $198.2 million, partially offset by a net decrease from changes in operating assets and liabilities of $69.1 million.

The following table presents cash flow impacts from changes in operating assets and liabilities, excluding the effects of foreign exchange rate fluctuations:


	For the Nine Months Ended September 30,
(in thousands)	2026		2025		Change

Accounts receivable	$	(72,762)	$	(82,586)	$	9,824
Inventories	(123)		(2,202)		2,079
Other assets and liabilities	(18,793)		(154,728)		135,935
Accounts payable	22,578		(4,977)		27,555
Total change in cash due to changes in operating assets and liabilities	$	(69,100)	$	(244,493)	$	175,393

Cash used by changes in operating assets and liabilities during the nine months ended September 30, 2026, decreased $175.4 million, compared to the same period during the prior year. The decrease in cash used for other assets and liabilities was primarily due to a payment in the prior year of approximately $80 million to conclude a litigation matter and a prior year decrease in income taxes payable associated with the acceleration of research and development deductions permitted under changes in U.S. tax law that were enacted in July 2025.

We have historically experienced proportionately lower net cash flows from operating activities during the first quarter and proportionately higher cash flows from operating activities for the remainder of the year, driven primarily by payments related to annual employee incentive programs in the first quarter following the year for which the bonuses were earned.

Investing Activities. Net cash used by investing activities was $307.1 million during the nine months ended September 30, 2026, compared to $108.1 million for the same period during the prior year. The increase in cash used by investing activities was primarily due to the acquisition of a software business, CoVet, in the current year, partially offset by lower capital expenditures for property, equipment, and intangible assets.

Our total capital expenditure plan for 2026 is estimated to be approximately $160.0 million, which includes capital investments in manufacturing and operations facilities to support growth, as well as investments in customer-facing software development.

Financing Activities. Net cash used by financing activities was $737.5 million during the nine months ended September 30, 2026, compared to $809.3 million used for the same period during the prior year. The decrease in net cash used was primarily due to a $169.2 million reduction in cash used for share repurchases, compared to the same period during the prior year, and $28.4 million in lower payments on our Seniors Notes, compared to the prior period, partially offset by $129.0 million less cash provided by net borrowings under our Credit Facility, compared to the prior period.

We believe that the repurchase of our common stock is a favorable means of returning value to our stockholders, and we also repurchase our stock to offset the dilutive effect of our share-based compensation programs. Repurchases of our common stock may vary depending upon the level of other investing and deployment activities, as well as share price and prevailing interest rates, and are subject to market conditions. Refer to “Note 12. Repurchases of Common Stock” to the unaudited condensed consolidated financial statements in “Part I. Item 1. Financial Statements” of this Quarterly Report on Form 10-Q for additional information about our share repurchases.

As of September 30, 2026, we had $474.0 million in outstanding borrowings under our Credit Facility, of which $250.0 million was on our Term Loan under our Credit Facility. Our Credit Facility contains affirmative, negative, and financial covenants customary for financings of this type. The negative covenants include restrictions on liens, indebtedness of subsidiaries of the Company, fundamental changes, investments, transactions with affiliates, certain restrictive agreements, and violations of sanctions laws and regulations.

We repaid the aggregate principal amount of $75.0 million on our 2026 Senior Notes at maturity during the third quarter of the current period. The aggregate principal amount of our 2027 Series B Notes will become due and payable on February 12, 2027. We anticipate funding the full repayment of our 2027 Series B Notes for $75.0 million when due on February 12, 2027, with available cash on hand, borrowings under our Credit Facility, proceeds from the issuance of new notes, or a combination thereof. The Senior Note Agreements contain affirmative, negative, and financial covenants customary for agreements of this type. The negative covenants include restrictions on liens, indebtedness of our subsidiaries, priority indebtedness, fundamental changes, investments, transactions with affiliates, certain restrictive agreements, and violations of sanctions laws and regulations.

The sole financial covenant under the Credit Facility and Senior Note Agreements is a consolidated leverage ratio test, calculated in accordance with the terms of each of these agreements, not to exceed 3.5-to-1. As of September 30, 2026, our consolidated leverage ratio, as defined in the Credit Facility and Senior Notes Agreements, was 0.5-to-1, and we were in compliance with all of the covenants of the Senior Note Agreements and Credit Facility.

Refer to “Note 11. Debt” to the unaudited condensed consolidated financial statements in “Part I. Item 1. Financial Statements” of this Quarterly Report on Form 10-Q for additional information about our Credit Facility and Senior Notes.

Effect of Currency Translation on Cash. The net effects of changes in foreign currency exchange rates are related to changes in exchange rates between the U.S. dollar and the functional currencies of our foreign subsidiaries with non-U.S. dollar functional currencies. These changes will fluctuate each year as the value of the U.S. dollar relative to the value of foreign currencies changes. The value of a currency depends on many factors, including interest rates and the issuing governments' debt levels and strength of economy.

Off-Balance Sheet Arrangements. We have no off-balance sheet arrangements or variable interest entities, except for letters of credit and third-party guarantees.

Other Commitments, Contingencies and Guarantees

Significant commitments, contingencies, and guarantees as of September 30, 2026, are described in “Note 16. Commitments, Contingencies and Guarantees” to the unaudited condensed consolidated financial statements in “Part I. Item 1. Financial Statements” of this Quarterly Report on Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

For quantitative and qualitative disclosures about market risk affecting us, refer to the section under the heading “Part II. Item 7A. Quantitative and Qualitative Disclosure About Market Risk” of our 2025 Annual Report. As of the date of this Quarterly Report on Form 10-Q, there have been no material changes to the market risks described in our 2025 Annual Report, except for the impact of foreign exchange rates, as discussed below.

Foreign Currency Exchange Impacts. Our foreign currency exchange impacts are comprised of three components: 1) local currency revenue and expenses; 2) the impact of foreign currency exchange hedge contracts; and 3) intercompany and monetary balances of our subsidiaries that are denominated in a currency that is different from the functional currency used by each subsidiary.

Approximately 24% and 23% of our consolidated revenue was derived from products manufactured or sourced in U.S. dollars and sold internationally in local currencies for the three and nine months ended September 30, 2026, respectively, compared to approximately 23% and 22% for the three and nine months ended September 30, 2025, respectively. Strengthening of the rate of exchange for the U.S. dollar relative to other currencies has a negative impact on our revenue derived in currencies other than the U.S. dollar and on profits of products manufactured or purchased in U.S. dollars and sold internationally, and a weakening of the U.S. dollar has the opposite effects. Similarly, to the extent that the U.S. dollar is stronger in current or future periods relative to the exchange rates in effect in the corresponding prior periods, our growth rate will be negatively affected. The impacts of foreign currency denominated costs and expenses and foreign currency denominated supply contracts partially offset this exposure. We also enter into foreign currency exchange contracts, designated as hedges, to manage the exchange risk associated with intercompany inventory purchases and sales that are denominated in certain currencies other than the U.S. dollar.

The following table presents the estimated foreign currency exchange impacts on our revenue, operating profit, and diluted earnings per share for the current period compared to the respective prior-year period:


	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
(in thousands, except per share amounts)	2026		2025		2026		2025

Revenue increase (decrease)	$	(2,371)	$	13,034	$	37,286	$	13,235

Operating profit increase (decrease), excluding hedge activity and exchange impacts on settlement of foreign currency denominated transactions	$	(1,028)	$	7,349	$	21,526	$	5,554
Hedge gains (losses) - current period	798		(1,965)		514		600
Foreign currency transactions gains (losses) - current period	812		(1,587)		122		(2,826)
Operating profit increase (decrease) - current period	582		3,797		22,162		3,328

Hedge (gains) losses - comparable period in the prior year	1,965		(512)		(600)		(3,043)
Foreign currency transaction (gains) losses - comparable period in the prior year	1,587		(1,381)		2,826		553
Operating profit increase (decrease) - compared to prior period	$	4,134	$	1,904	$	24,388	$	838

Diluted earnings per share increase (decrease) - compared to prior period (1)	$	0.04	$	0.02	$	0.24	$	0.01

(1) The impacts on diluted earnings per share presented may not recalculate due to rounding.

At our current foreign exchange rate assumptions, we anticipate year-over-year changes for the remainder of the year will decrease our revenue, and increase operating profit and diluted earnings per share by approximately $8 million, $1 million and $0.01 per share, respectively. These favorable currency impacts to our operating profit and diluted earnings per share include net year-over-year impacts of foreign currency hedging activity, which is expected to increase our total operating profit by approximately $4 million and $0.04 per share for the remainder of the year ending December 31, 2026. These estimates assume that the value of the U.S. dollar will reflect the euro at $1.12, the British pound at $1.32, the Canadian dollar at $0.70, and the Australian dollar at $0.69; and the Japanese yen at ¥160, the Chinese renminbi at RMB 6.80, and the Brazilian real at R$5.05 relative to the U.S. dollar for the remainder of 2026. The actual impact of changes in the value of the U.S. dollar against foreign currencies in which we transact may materially differ from our expectations.

The foreign currency exchange impacts on our projected revenue and expenses for the remainder of 2026 will be different from our estimates if actual foreign exchange rates are different from our assumptions. Excluding the impact of intercompany and trade balances denominated in currencies other than the functional subsidiary currencies, we project a 1% strengthening of the U.S. dollar would reduce revenue by approximately $4 million and operating income by approximately $2 million, net of hedge positions.

Interest Rate Risk. We entered into an interest rate swap to reduce the effect of variable interest obligations of our Term Loan. Beginning in November 2025, the variable interest rate associated with our $250.0 million Term Loan became effectively fixed at 3.4%, plus the applicable credit spread, through November 12, 2028. Borrowings outstanding under our Credit Facility at September 30, 2026, were $474.0 million. We have designated the interest rate swap as a cash flow hedge. For more information regarding our interest rate swap, refer to “Part I, Item 1. Financial Statements, Note 19. Hedging Instruments.”

Effects of Inflation. We expect to continue to face higher costs for labor, commodities, energy, and transportation, as well as increased prices from suppliers. We may not be able to offset these higher costs through productivity initiatives and price increases, which may materially and adversely affect our business, results of operations, and financial condition. Any price increases we may impose may lead to declines in sales volume or loss of business, if competitors do not similarly adjust their prices, or customers refuse to purchase at the higher prices.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

Our management is responsible for establishing and maintaining disclosure controls and procedures, as defined by the SEC in its Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of September 30, 2026, our Chief Executive Officer and our Chief Financial Officer have concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended September 30, 2026, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

Due to the nature of our activities, we are at times subject to pending and threatened legal actions that arise out of the ordinary course of business. In the opinion of management, based in part upon advice of legal counsel, the disposition of any such currently pending or threatened matters is not expected to have a material effect on our results of operations, financial condition, or cash flows. However, the results of legal actions cannot be predicted with certainty. Therefore, it is possible that our results of operations, financial condition, or cash flows could be materially adversely affected in any particular period by the unfavorable resolution of one or more legal actions.

Item 1A. Risk Factors

In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the risk factors discussed in “Part I. Item 1A. Risk Factors” in our 2025 Annual Report, which could materially affect our business, financial condition, or future results. There have been no material changes from the risk factors previously disclosed in the 2025 Annual Report. The risks described in our 2025 Annual Report are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition, or future results.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

During the three months ended September 30, 2026, we repurchased shares of common stock as described below:


Period	Total Number of Shares Purchased (a)		Average Price Paid per Share (b)(3)		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs (1) (c)	Maximum Number of Shares that May Yet Be Purchased Under the Plans or Programs (1) (d)

July 1 to July 31, 2026	172,200		$	559.54	172,200	2,380,370
August 1 to August 31, 2026	26,400		$	585.84	26,400	2,353,970

Total	198,875	(2)			198,600	2,353,970

(1)Our Board of Directors has approved the repurchase of up to 78 million shares of our common stock in the open market or in negotiated transactions pursuant to the Company’s share repurchase program. The initial program was approved and announced on August 13, 1999, and the maximum number of shares that may be purchased under the program has been increased by the Board of Directors on numerous occasions. There is no specified expiration date for this repurchase program, and it may be suspended or discontinued at any time. There were no other repurchase programs outstanding during the three months ended September 30, 2026, and no share repurchase programs expired during the period.

(2)During the three months ended September 30, 2026, we received 275 shares of our common stock that were surrendered by employees in payment for the minimum required withholding taxes due on the vesting of restricted stock units. In the above table, these shares are included in columns (a) and (b), but excluded from columns (c) and (d). These shares do not reduce the number of shares that may yet be purchased under the share repurchase program.

(3)Includes a 1% excise tax on the value of shares repurchased in the open market, net of a reduction for eligible stock issuances.

Refer to “Note 12. Repurchases of Common Stock” to the unaudited condensed consolidated financial statements in “Part I. Item 1. Financial Statements” of this Quarterly Report on Form 10-Q for additional information about our share repurchases.

Item 5. Other Information

Rule 10b5-1 Trading Plan Elections

During the three months ended September 30, 2026, none of our directors or officers (as defined in Rule 16a-1(f) under the Exchange Act) adopted, modified, or terminated any “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement” (as such terms are defined in Item 408(a) of Regulation S-K.
