On a GAAP basis, diluted earnings per share (EPS) for the third quarter of 2025 were $2.50, compared to $2.71 for the third quarter of 2024. Non-GAAP EPS for the third quarter of 2025 grew 16% to $3.40, compared to $2.93 for the third quarter of 2024.

“Our team yet again delivered outstanding results, driven by strong execution and our differentiated product portfolio. Pharma grew double digits as the instrument replacement cycle entered its second year, and new LC-MS and chemistry products captured opportunities from the growing share of biologics and novel modalities in the pharma pipeline,” said Dr. Udit Batra, President & CEO of Waters Corporation.

Dr. Batra continued, “Our chemistry portfolio continues to set the standard in the industry, with excellent customer reception of our new Affinity bioseparation columns. In bioanalytical characterization, we have worked closely with customers to develop the Xevo™ Charge Detection Mass Spectrometer, which uses up to 100-fold less sample volume than current techniques and delivers results in under 10 minutes.”

“We will uphold the same high standards of innovation, operational excellence, and execution in BD's Biosciences & Diagnostic Solutions business as we accelerate our long-term growth strategy. Integration planning is progressing as expected, and we remain highly confident in the achievability of the significant cost and revenue synergies we have identified.”

Non-GAAP Financial Measures

This release contains financial measures, such as constant currency growth rates, 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 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. Definitions of the non-GAAP financial measures and reconciliations to the most directly comparable GAAP financial measures are included in the tables accompanying this release.

________________________________________(a) Selling & administrative expenses include purchased intangibles amortization and litigation provisions and settlements.(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) 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.(d) ERP implementation and transformation costs represent costs related to the Company's initiative to transition from its legacy enterprise resource planning (ERP) system to a new global ERP solution with a cloud-based infrastructure. These costs, which do not represent normal or future ongoing business expenses, are one-time, non-recurring costs related to the establishment of our new global ERP solution that were determined to be non-capitalizable in accordance with accounting standards.(e) Acquisition related costs include all incremental costs incurred to effect the business combination, such as advisory, legal, accounting, tax, valuation, other professional fees, and integration costs. The Company believes that these costs are not normal and do not represent future ongoing business expenses.(f) Litigation provisions and settlement gains were excluded as these items are isolated, unpredictable and not expected to recur regularly.(g) In connection with the Wyatt acquisition, the Company recognized 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.(h) Financing costs relate to certain financing fees incurred by the Company to secure access to certain debt facilities in connection with the agreement Waters entered into to acquire the Biosciences and Diagnostics Solutions business of Becton, Dickinson & Company. The Company believes that these costs are not normal and do not represent future ongoing business expenses.

(a) Constant currency growth rates are a non-GAAP financial measure that measures the change in net sales between current and prior year periods, excluding the impact of foreign currency exchange rates 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.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.
