PART III – NARRATIVE State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-CEN, N-CSR, or the transition report portion thereof, could not be filed within the prescribed time period. Mechanics Bancorp (the “Company”) has determined that it is unable, without unreasonable effort or expense, to file its Quarterly Report on Form 10-Q for the period ended September 30, 2025 (the “Form 10-Q”) by the prescribed due date, November 10, 2025. As previously disclosed in its Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission (the “SEC”) on September 2, 2025, the Company completed on September 2, 2025 the merger contemplated by that certain Agreement and Plan of Merger, dated as of March 28, 2025, by and among the Company, HomeStreet Bank and Mechanics Bank, pursuant to which HomeStreet Bank merged with and into Mechanics Bank (the “Merger”) with Mechanics Bank surviving the Merger and becoming a wholly-owned subsidiary of the Company. The Company is in the process of finalizing its review of the preliminary purchase accounting adjustments to be recorded in connection with the Merger and, consequently, is in the process of finalizing the Form 10-Q to reflect those items. The Company intends to file the Form 10-Q with the SEC as promptly as practicable. The Company is presently not aware of any circumstances that would prevent it from filing the Form 10-Q on or before the fifth (5th) calendar day following the prescribed due date in compliance with Rule 12b-25 under the Securities Exchange Act of 1934, as amended.
