Forward-Looking Statements

This press release contains statements that constitute “forward-looking statements” within the meaning of, and subject to the protections of, the Private Securities Litigation Reform Act of 1995. Factors that could cause Webster’s actual results to differ from those described in the forward-looking statements are described in Webster’s Annual Report on Form 10-K for the year ended December 31, 2025, as amended, and in Webster’s subsequent filings with the U.S. Securities and Exchange Commission. Any forward-looking statement made by Webster in this release speaks only as of the date on which it is made. Factors or events that could cause Webster’s actual results to differ may emerge from time to time, and it is not possible for Webster to predict all of them. Webster undertakes no obligation to publicly update any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by law.

Non-GAAP Financial Measures

In addition to results presented in accordance with GAAP, this press release contains certain non-GAAP financial measures, including the efficiency ratio, the return on average tangible common stockholders’ equity, the tangible equity ratio, the tangible common equity ratio, tangible book value per common share, core deposits, adjusted return on average assets, adjusted return on average tangible common stockholders’ equity, adjusted pre-tax net income, adjusted net income applicable to common stockholders, and adjusted diluted earnings per share (“EPS”). A reconciliation of each non-GAAP financial measure to the most comparable GAAP financial measure is included in the accompanying selected financial highlights table.

Webster believes that certain non-GAAP financial measures provide investors with information useful in understanding its financial position, results of operations, the strength of its capital position, and overall business performance. These non-GAAP financial measures are used by Webster for performance measurement purposes, as well as for internal planning and forecasting, and by securities analysts, investors, and other interested parties to assess peer company operating performance. Webster believes that this presentation, together with the accompanying reconciliations, provides investors with a more complete understanding of the factors and trends affecting its business and allows investors to view its performance in a manner similar to management.

The efficiency ratio represents the costs expended to generate a dollar of revenue and is calculated excluding certain non-operational items and certain non-recurring transactions or events. The return on average tangible common stockholders’ equity is calculated using net income less preferred stock dividends, adjusted for the tax-effected amortization of intangible assets, as a percentage of average stockholders’ equity less average preferred stock and average goodwill and other intangible assets. The tangible equity ratio represents stockholders’ equity less goodwill and other intangible assets (“tangible stockholders’ equity”) divided by total assets less goodwill and other intangible assets (“tangible assets”). The tangible common equity ratio represents stockholders’ equity less preferred stock and goodwill and other intangible assets (“tangible common stockholders’ equity”) divided by tangible assets. Tangible book value per common share represents tangible common stockholders’ equity divided by the number of common shares outstanding at the end of the reporting period. Core deposits reflect total deposits less certificates of deposit and brokered certificates of deposit. The adjusted return on average assets, adjusted return on average tangible common stockholders’ equity, adjusted pre-tax net income, adjusted net income applicable to common stockholders, and adjusted diluted EPS are calculated excluding certain non-recurring transactions or events, which have been tax-effected, as applicable.

These non-GAAP financial measures should not be considered a substitute for GAAP-basis financial measures. Because non-GAAP financial measures are not standardized, it may not be possible to compare these with other companies that present financial measures having the same or similar names. Webster strongly encourages investors to review its consolidated financial statements in their entirety and to not rely on any single financial measure. Refer the tables beginning on page 12 for Non-GAAP to GAAP reconciliations.
