Pursuant to the Agreement and Plan of Merger, dated as of March 28, 2025, among HomeStreet, Inc., HomeStreet Bank, a subsidiary of HomeStreet, Inc., and Mechanics Bank, at the effective time of the merger on September 2, 2025, each outstanding PSU held by the Reporting Person was accelerated and entitled the Reporting Person to receive shares of Issuer Class A common stock, plus a cash amount for any accrued but unpaid dividends on the PSUs.  In the merger, HomeStreet, Inc. was renamed Mechanics Bancorp.</footnote>

The number of shares issued on the vesting of the PSU was determined based on the achievement of certain performance factors set forth in the PSU.  The unvested portion of the PSU was cancelled.</footnote>
