Non-GAAP Financial Measures

This press release contains financial measures, such as constant currency growth rate, adjusted operating income, adjusted net income, adjusted earnings per diluted share and adjusted 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

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 the timing of the closing of the transaction, prospects for regulatory approval, the timing and success of integration efforts once the transaction is complete, expectations or ability to realize commercial success, the impact of this transaction, if successful, 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, market prospects for its products and sales and earnings guidance; the effects of the ongoing COVID-19 pandemic on our business, financial condition, results of operations and prospects, including: portions of our global workforce being unable to work fully and/or effectively due to working remotely, illness, quarantines, including the impact from the lockdown in China, government actions, facility closures or other reasons related to the pandemic, increased risks of cyber-attacks resulting from our temporary remote working model, disruptions in our manufacturing capabilities or to our supply chain and distribution network, volatility and uncertainty in global capital markets limiting our ability to access capital, customers being unable to make timely payments for purchases and volatility in demand for our products; 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; the impact on demand for the Company’s products, including delays or disruptions to our distribution network, among the Company’s various market sectors or geographies from economic, sovereign and political conditions and uncertainties, particularly regarding the effect of new or proposed tariff or trade regulations or changes in the interpretation or enforcement of existing regulations; the effect on the Company’s financial results from the United Kingdom exiting the European Union, as well as the Chinese government’s ongoing tightening of restrictions on procurement by government-funded customers; fluctuations in expenditures by the Company’s customers, in particular large pharmaceutical companies; introduction of competing products by other companies and loss of market share; pressures on prices from competitors and/or customers; regulatory, economic and competitive obstacles to new product introductions; lack of acceptance of new products; expansion of our business in developing markets; spending by certain end-markets; ability to obtain alternative sources for components and modules; and the possibility that future sales of new products related to acquisitions, which trigger contingent purchase payments, may exceed the Company’s expectations; other changes in demand for the Company’s products from the effect of mergers and acquisitions by the Company’s customers; 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; as well as 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; shifts in taxable income in jurisdictions with different effective tax rates; the outcome of tax examinations or changes in respective country legislation affecting the Company’s effective tax rate; the effect of the adoption of new accounting standards; the ability to access capital, maintain liquidity and service the Company’s debt in volatile market conditions, including any potential impact on the Company’s operations stemming from sustained inflation, particularly in the U.S., as a large portion of the Company’s cash is held and operating cash flows are generated outside the U.S.; environmental and logistical obstacles affecting the distribution of products and risks associated with lawsuits and other legal actions, particularly involving claims for infringement of patents and other intellectual property rights; and the impact and costs of war, in particular as a result of the ongoing conflict between Russia and Ukraine, and the possibility of further escalation resulting in a new geopolitical and regulatory instability.

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, 2021, as well as in the sections entitled “Special Note Regarding Forward-Looking Statements” and “Risk Factors” of the Company’s quarterly reports on Form 10-Q for the quarterly periods ended April 2, 2022, July 2, 2022, and October 1, 2022 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) Selling & administrative expenses include purchased intangibles amortization, litigation provisions and settlements and asset impairments.

(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) Acquired in-process research and development was excluded as it relates to the cost of a licensing arrangement for charge detection mass spectrometry that the Company believes is unusual and not indicative of its normal business operations.

(d) Restructuring costs, mergers and acquisition costs and certain other items were excluded as the Company believes that the cost to consolidate operations, reduce overhead, acquire companies 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) The pension settlement and curtailment expenses associated with certain defined benefit pension plans were excluded as the Company believes these expenses are not indicative of normal operating costs.

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

(g) Certain income tax items were excluded as these non-cash expenses and benefits represent updates in management’s assessment of ongoing examinations or other tax items that are not indicative of the Company’s normal or future income tax expense.

Adjusted non-GAAP earnings per diluted share Including impact of recently announced acquisitions	$	2.55		—	$	2.65		$	12.55		—	$	12.75

(a) Organic constant currency growth rates are a non-GAAP financial measure that measures the change in net sales between current and prior year periods, ignoring the impact of foreign currency exchange rates and revenue from recently announced acquisitions during the current period. 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.

(b) Projected earnings per diluted share estimates exclude the impact of certain transaction costs, amortization of purchased intangibles, and other costs related to recently announced acquisitions as the amounts cannot be reasonably estimated as of the date of this press release.

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.
