Subsequent Events [Abstract] |
Subsequent Events | Subsequent Events The Company has evaluated subsequent events from the date of the Consolidated Financial Statements, and accompanying Notes thereto, through the date of issuance, and determined that, other than the below, there were no other significant events identified requiring recognition for disclosure. Proposed Transaction with Banco Santander On February 3, 2026, Webster entered into a Transaction Agreement with Banco Santander and Webster Virginia Corporation, a wholly owned subsidiary of Webster incorporated in the State of Virginia. The Transaction Agreement provides that, upon the terms and subject to the conditions set forth therein, Banco Santander will acquire Webster in two steps. First, Webster will merge with and into Webster Virginia Corporation, with Webster Virginia Corporation continuing as the surviving corporation in such merger. Second, immediately following the completion of such merger, Banco Santander will acquire all outstanding shares of Webster Virginia Corporation through a statutory share exchange. Based on Banco Santander’s closing stock price on February 2, 2026, the Transaction has an aggregate value of approximately $12.3 billion. Under the terms of the Transaction Agreement, holders of Webster common stock will receive $48.75 in cash and 2.0548 ADSs (or Ordinary Shares in certain circumstances) for each share of Webster common stock that they own. The Transaction Agreement contains customary representations and warranties, covenants, and closing conditions. Completion of the Transaction remains subject to approval by the Federal Reserve and the European Central Bank, approval by the stockholders of each company, and other customary closing conditions. The Transaction is expected to close in the second half of 2026.
