Forward-Looking Statements & Non-GAAP Financial Measures This presentation contains forward-looking statements regarding future results and events, including financial and operational guidance and projected estimates. For this purpose, any statements that are not statements of historical fact may be deemed forward-looking statements. Words such as “may,” “will,” “expect,” “plan,” “anticipate,” “estimate,” “intend,” “outlook,” and similar expressions (as well as other words or expressions referencing future events, conditions or circumstances) are intended to identify forward-looking statements. These forward-looking statements may include statements regarding future operating and financial performance, market growth, success of our products, customer trends, and the acquisition of Wyatt Technology and the realization of the benefits thereof. Forward-looking statements in this presentation are based on Waters’ expectations and assumptions as of the date of this presentation and are neither predictions nor guarantees of future events or performance. You should not place undue reliance on forward-looking statements, which speak only as of the date hereof and should not be relied upon as representing the Company’s estimates or views as of any date subsequent to the date of this presentation. Each of these forward-looking statements involves risks and uncertainties, including risks and uncertainties associated with the Wyatt acquisition, as well as the Company’s ability to realize the expected benefits related to its various cost-saving initiatives, and actual results may differ materially from such forward-looking statements. We discuss various factors that may cause Waters actual results to differ from those expressed or implied in the forward-looking statements in this presentation, including, but not limited to, those factors relating to the impact on Waters’ operating results throughout the Company’s various market sectors or geographies from economic, environmental, regulatory, sovereign and political uncertainties, in the sections entitled “Forward-Looking Statements,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations”, and “Risk Factors” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 as filed with the Securities and Exchange Commission (“SEC”) on February 27, 2024, as updated by the Company’s subsequent filings with the SEC, including the Company’s Quarterly Reports on Form 10-Q. Except as required by law, Waters does not assume any obligation to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise. To supplement the Company’s financial statements presented on a GAAP basis, the Company has provided certain non-GAAP financial measures, such as organic constant currency revenue, adjusted operating margin, free cash flow, and non-GAAP diluted earnings per share. Management uses these non-GAAP financial measures to evaluate the Company’s operating performance in a manner that allows for meaningful period-to-period comparison and analysis of trends in its business. Management believes that such measures are important in comparing current results with prior period results and are useful to investors and financial analysts in assessing the Company’s operating performance. The non-GAAP financial information presented herein should be considered in conjunction with, and not as a substitute for, the financial information presented in accordance with GAAP. Management strongly encourages investors to review the Company’s consolidated financial statements and publicly filed reports in their entirety. The Company’s definition of these non-GAAP financial measures may differ from similarly titled measures used by others. The non-GAAP financial measures used in this presentation adjust for specified items that can be highly variable or difficult to predict. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measures using a reconciliation of these measures included in the Appendix to this presentation and which can also be found on the company’s website at: https://ir.waters.com/. ©2025 Waters Corporation 1
