The compensatory arrangement for Mr. Madar as Interim Chief Accounting Officer has not been determined as of the date of this report.

On September 4, 2025, Webster Financial Corporation (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with BofA Securities, Inc., Goldman Sachs & Co. LLC, J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC, as representatives of the several underwriters named in Schedule 1 thereto (the “Underwriters”). Pursuant to the terms of the Underwriting Agreement, the Company agreed to sell, and the Underwriters agreed to purchase severally, subject to and on the conditions set forth therein, $350,000,000 aggregate principal amount of the Company’s 5.784% Fixed Rate Reset Subordinated Notes due 2035 (the “Notes”) in a registered public offering pursuant to an effective shelf registration statement on Form S-3 (Registration File No. 333-276034).

On September 11, 2025, the Company issued and sold the Notes pursuant to a Subordinated Debt Indenture dated as of September 11, 2025 (the “Base Indenture”), between the Company and U.S. Bank Trust Company, National Association, as trustee, as supplemented by a First Supplemental Indenture dated as of September 11, 2025 to the Base Indenture (the “First Supplemental Indenture” and, together with the Base Indenture, the “Indenture”). The Notes will mature on September 11, 2035 (the “Maturity Date”). From and including September 11, 2025 to, but excluding, September 11, 2030, the Notes shall bear interest at a fixed rate per annum equal to 5.784%. From and including September 11, 2030 (the “reset date”) to, but excluding, the Maturity Date, the Notes shall bear interest at a fixed rate per annum equal to the U.S. Treasury Rate for a five-year maturity as of the third business day preceding the reset date, plus a spread of 212.5 basis points, provided that in the event the interest rate is less than zero, the interest rate shall be deemed to be zero. Interest on the Notes shall be payable semiannually in arrears on March 11 and September 11 of each year, commencing on March 11, 2026. The Company may redeem the Notes at such times and at the redemption prices as provided for in the Indenture.

The preceding is a summary of the terms of the Underwriting Agreement, the Base Indenture, the First Supplemental Indenture and the form of the Notes, and is qualified in its entirety by reference to the Underwriting Agreement filed as Exhibit 1.1 to this report, the Base Indenture filed as Exhibit 4.1 to this report, the First Supplemental Indenture filed as Exhibit 4.2 to this report, and the form of the Notes filed as Exhibit 4.3 to this report, which are incorporated herein by reference as though they were fully set forth herein.
