Webster Financial Corporation, a Delaware corporation (the “Registrant”), is filing this Post-Effective Amendment No. 1 to Registration Statement No. 333-276034 on Form S-3ASR (the “Registration Statement”), which was previously filed by the Registrant with the Securities and Exchange Commission (the “Commission”) on December 14, 2023, pertaining to the registration of an indeterminate number of (i) debt securities of the Registrant; (ii) shares of common stock, par value $0.01 per share (“Common Stock”), of the Registrant, (iii) shares of preferred stock (“Preferred Stock”) of the Registrant, (iv) depositary shares of the Registrant representing shares of Preferred Stock, (v) purchase contracts obligating the Registrant to sell, and holders to purchase, debt securities of the Registrant, shares of Common Stock, shares of Preferred Stock, depositary shares or warrants at a future date or dates, (vi) units comprised of one or more of the securities described in the Registration Statement in any combination and (vii) warrants to purchase debt securities of the Registrant, shares of Common Stock, shares of Preferred Stock, debt securities or units of two or more of the foregoing securities of the Registrant.

On August 20, 2026, pursuant to the Transaction Agreement, dated as of February 3, 2026 (the “Transaction Agreement”), by and among the Registrant, Banco Santander, S.A., a Spanish sociedad anónima (“Banco Santander”), and Webster Virginia Corporation, a wholly-owned subsidiary of the Registrant incorporated in the State of Virginia (“Webster Virginia”), (i) the Registrant merged with and into Webster Virginia (the “Reincorporation Merger”), with Webster Virginia continuing as the surviving corporation in the Reincorporation Merger, and (ii) immediately thereafter, Banco Santander acquired all outstanding shares of the common stock, par value $0.01 per share, of Webster Virginia through a statutory share exchange (the “Share Exchange”).

Immediately after the Share Exchange, (i) Banco Santander contributed all outstanding shares of the common stock, par value $0.01 per share, of Webster Virginia to Santander Holdings USA, Inc. (“SHUSA”) and (ii) immediately following such contribution, pursuant to the Agreement and Plan of Merger, dated as of August 19, 2026, by and between SHUSA and Webster Virginia (the “Merger Agreement”), Webster Virginia merged with and into SHUSA (the “IHC Merger” and, together with the Reincorporation Merger and the Share Exchange, the “Transactions”), with SHUSA continuing as the surviving corporation in the IHC Merger.

The foregoing description of the Transaction Agreement, the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety, by (i) the Transaction Agreement, which is attached as Exhibit 2.1 to the Registrant’s Current Report on Form 8-K filed with the Commission on February 6, 2026 and (ii) the Merger Agreement, which is attached as Exhibit 2.3 to SHUSA’s Current Report on Form 8-K filed with the Commission on August 20, 2026.

In connection with the completion of the Transactions, the Registrant has terminated all offerings of the Registrant’s securities pursuant to the Registration Statement. In accordance with the undertakings made by the Registrant in the Registration Statement to remove from registration, by means of a post-effective amendment, any securities that had been registered for issuance but remain unsold at the termination of the offerings, the Registrant hereby removes from registration any and all securities of the Registrant registered but unsold under the Registration Statement as of the date hereof.
