WASHINGTON TRUST BANCORP INC

The management of the Corporation is responsible for establishing and maintaining adequate internal control over financial reporting. The Corporation’s internal control over financial reporting is a process designed under the supervision of the Corporation’s Chief Executive Officer and Chief Financial Officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Corporation’s Consolidated Financial Statements for external reporting purposes in accordance with GAAP.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect all misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

Based on this assessment, management concluded that the Corporation’s internal control over financial reporting as of December 31, 2023 was effective.
