NATURE OF BUSINESS, BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION

The accompanying consolidated financial statements of IDEXX Laboratories, Inc. and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and with the requirements of Regulation S-X.

These statements include the accounts of IDEXX Laboratories, Inc., and our wholly-owned subsidiaries (“IDEXX,” the “Company,” “we,” or “our”). 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.

Impairment charges incurred in the years ended December 31, 2024 and 2023, were recast to other adjustments to reconcile net income to net cash provided by operating activities on the Consolidated Statements of Cash Flows to conform to the current‑period presentation. The recast had no impact on net cash provided by operating activities for any period presented.
