PART III — NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

The Form 11-K which is the subject of this 12b-25 extension is being filed in order to report the information required of the First Seacoast Bank 401(k) Plan (the “Plan”). Although the Plan’s Annual Report on Form 11-K for the year ended December 31, 2025 had been fully prepared within the prescribed time period, the Plan was unable to complete the necessary iXBRL tagging and testing without unreasonable effort or expense. In order to ensure the accuracy of the information contained in the Form 11-K, the Plan believes it is necessary to obtain an extension of the filing date. The Registrant plans to file the Form 11-K no later than the fifteenth calendar day following the prescribed due date.
