Non-GAAP Financial Measures

This press release contains financial measures, such as organic constant currency growth rates, adjusted operating income, adjusted net income, adjusted earnings per diluted share and free cash flow, among others, which are considered “non-GAAP” financial measures under applicable U.S. Securities and Exchange Commission rules and regulations. These non-GAAP financial measures should be considered supplemental to, and not a substitute for, financial information prepared in accordance with U.S. generally accepted accounting principles (GAAP). The Company’s definitions of these non-GAAP measures may differ from similarly titled measures used by others. The non-GAAP financial measures used in this press release adjust for specified items that can be highly variable or difficult to predict. The Company generally uses these non-GAAP financial measures to facilitate management’s financial and operational decision-making, including evaluation of the Company’s historical operating results, comparison to competitors’ operating results and determination of management incentive compensation. These non-GAAP financial measures reflect an additional way of viewing aspects of the Company’s operations that, when viewed with GAAP results and the reconciliations to corresponding GAAP financial measures, may provide a more complete understanding of factors and trends affecting the Company’s business. Because non-GAAP financial measures exclude the effect of items that will increase or decrease the Company’s reported results of operations, management strongly encourages investors to review the Company’s consolidated financial statements and publicly filed reports in their entirety. Reconciliations of the non-GAAP financial measures to the most directly comparable GAAP financial measures are included in the tables accompanying this release.

Cautionary Statement

This release contains “forward-looking” statements regarding future results and events. For this purpose, any statements that are not statements of historical fact may be deemed forward-looking statements. Without limiting the foregoing, the words “feels”, “believes”, “anticipates”, “plans”, “expects”, “intends”, “suggests”, “appears”, “estimates”, “projects” and similar expressions, whether in the negative or affirmative, are intended to

identify forward-looking statements. The Company’s actual future results may differ significantly from the results discussed in the forward-looking statements within this release for a variety of reasons, including and without limitation, risks related to, and expectations or ability to realize commercial success of the Wyatt transaction; the impact of this transaction on the Company’s business, anticipated progress on Waters’ research programs, development of new analytical instruments and associated software or consumables, manufacturing development and capabilities; the increased indebtedness of the Company as a result of the Wyatt transaction, the repayment of which could impact the Company’s future results, market prospects for its products and sales and earnings guidance; foreign currency exchange rate fluctuations potentially affecting translation of the Company’s future non-U.S. operating results, particularly when a foreign currency weakens against the U.S. dollar; current global economic, sovereign and political conditions and uncertainties, including the effect of new or proposed tariff or trade regulations as well as other new or changed domestic and foreign laws, regulations and policies; changes in inflation and interest rates; the impacts and costs of war, in particular as a result of the ongoing conflicts between Russia and Ukraine and in the Middle East, and the possibility of further escalation resulting in new geopolitical and regulatory instability; the Chinese government’s ongoing tightening of restrictions on procurement by government-funded customers; the Company’s ability to access capital, maintain liquidity and service the Company’s debt in volatile market conditions; risks related to the effects of any pandemic on our business, financial condition, results of operations and prospects; changes in timing and demand for the Company’s products among the Company’s customers and various market sectors, particularly as a result of fluctuations in their expenditures or ability to obtain funding; the ability to realize the expected benefits related to the Company’s various cost-saving initiatives, including workforce reductions and organizational restructurings; the introduction of competing products by other companies and loss of market share, as well as pressures on prices from competitors and/or customers; changes in the competitive landscape as a result of changes in ownership, mergers and continued consolidation among the Company’s competitors; regulatory, economic and competitive obstacles to new product introductions; lack of acceptance of new products and inability to grow organically through innovation; rapidly changing technology and product obsolescence; risks associated with previous or future acquisitions, strategic investments, joint ventures and divestitures, including risks associated with achieving the anticipated financial results and operational synergies; contingent purchase price payments and expansion of our business into new or developing markets; risks associated with unexpected disruptions in operations; failure to adequately protect the Company’s intellectual property, infringement of intellectual property rights of third parties and inability to obtain licenses on commercially reasonable terms; the Company’s ability to acquire adequate sources of supply and its reliance on outside contractors for certain components and modules, as well as disruptions to its supply chain; risks associated with third-party sales intermediaries and resellers; the impact and costs of changes in statutory or contractual tax rates in jurisdictions in which the Company operates as well as shifts in taxable income among jurisdictions with different effective tax rates, the outcome of ongoing and future tax examinations and changes in legislation affecting the Company’s effective tax rate; the Company’s ability to attract and retain qualified employees and management personnel; risks associated with cybersecurity and technology, including attempts by third parties to defeat the security measures of the Company and its third-party partners; increased regulatory burdens as the Company’s business evolves, especially with respect to the U.S. Food and Drug Administration and U.S. Environmental Protection Agency, among others, and in connection with government contracts; regulatory, environmental and logistical obstacles affecting the distribution of the Company’s products, completion of purchase order documentation and the ability of customers to obtain letters of credit or other financing alternatives; risks associated with litigation and other legal and regulatory proceedings; and the impact and costs incurred from changes in accounting principles and practices. Such factors and others are discussed more fully in the sections entitled “Forward-Looking Statements” 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”), which discussions are incorporated by reference in this release, as updated by the Company’s future filings with the SEC.

(a)

The Company believes that referring to comparable organic constant currency growth rates is a useful way to evaluate the underlying performance of Waters Corporation’s net sales. Organic constant currency growth, a non-GAAP financial measure, measures the change in net sales between current and prior year periods, excluding the impact of foreign currency exchange rates during the current period and excluding the impact of acquisitions made within twelve months of the acquisition close date. See description of non-GAAP financial measures contained in this release.

(a)	Selling & administrative expenses include purchased intangibles amortization.

(b)	The purchased intangibles amortization, a non-cash expense, was excluded to be consistent with how management evaluates the performance of its core business against historical operating results and the operating results of competitors over periods of time.

(c)	Litigation provisions and settlement gains were excluded as these items are isolated, unpredictable and not expected to recur regularly.

(d)

Restructuring costs and certain other items were excluded as the Company believes that the cost to consolidate operations, reduce overhead, and certain other income or expense items are not normal and do not represent future ongoing business expenses of a specific function or geographic location of the Company.

(e)	Acquisition related costs include all incremental expenses incurred, such as advisory, legal, accounting, tax, valuation, and other professional fees. The Company believes that these costs are not normal and do not represent future ongoing business expenses.

(f)

In connection with the Wyatt acquisition, the Company started to recognize a two-year retention bonus obligation that is contingent upon the employee’s providing future service and continued employment with Waters. The Company believes that these costs are not normal and do not represent future ongoing business expenses.

These amounts are estimated at the current foreign currency exchange rates and based on the forecasted geographical sales in local currency, as well as an assessment of market conditions as of today, and may differ significantly from actual results.

These forward-looking adjustment estimates do not reflect future gains and charges that are inherently difficult to predict and estimate due to their unknown timing, effect and/or significance.
