REVVITY, INC.

The preparation of condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to accounting for business combinations, divestitures, long-lived assets, including goodwill and other intangible assets, and employee compensation and benefits. We base our estimates on historical experience and on various other 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 under different assumptions or conditions.

Critical accounting policies are those policies that affect our more significant judgments and estimates used in the preparation of our condensed consolidated financial statements. We believe our critical accounting policies include policies regarding business combinations, divestitures, valuation of long-lived assets, including goodwill and other intangibles and employee compensation and benefits.

For a more detailed discussion of our critical accounting policies and estimates, refer to the Notes to our audited consolidated financial statements and Item 7.“Management’s Discussion and Analysis of Financial Condition and Results of Operations,” in our Annual Report on Form 10-K for the fiscal year ended December 29, 2024 (our “2024 Form 10-K”), as filed with the Securities and Exchange Commission. There have been no significant changes in our critical accounting policies and estimates during the nine months ended September 28, 2025.
