As anticipated, our second quarter revenue declined due to the ongoing impacts of the COVID-19 pandemic. However, our results reflected modestly

better-than-anticipated market conditions and strong execution by our global sales, service and operations teams, commented Chris O Connell, President and Chief Executive Officer of Waters Corporation. This revenue performance,

combined with the benefits of our cost containment initiatives, drove solid margin and earnings results during the quarter. While risks and uncertainties remain in our operating environment, we are well-positioned to leverage our strong new product

pipeline and are investing to take advantage of growth opportunities as demand normalizes.

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 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 Waters Corporation 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 Waters Corporation 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.
