Explanation of Responses:
1. Each Restricted Stock Unit ("RSU") represents a contingent right to receive one share of Mechanics Bancorp (the "Company") Class A common stock. RSUs do not require the holder to pay any consideration on vesting.
2. Granted but unvested RSUs were previously reported in Table I. Going forward, granted but unvested RSUs will be reported in Table II and will be reported in Table I when they vest and convert into Class A common stock. Share totals of securities beneficially owned following reported transaction(s) reported in Table I have been adjusted to reflect this change in reporting and do not include unvested RSUs.
3. On May 21, 2025, the Reporting Person was granted the equivalent of 3,301 of the Company's RSUs, which vest on May 27, 2026. Upon vesting, the Reporting Person will receive a number of shares of the Company's Class A common stock equal to the number of RSU's that vest on that date.
4. On May 28, 2026, the Reporting Person was granted 5,513 RSUs, which vest on May 28, 2027. Upon vesting, the Reporting Person will receive a number of shares of the Company's Class A common stock equal to the number of RSU's that vest on that date.
5. Each incentive unit is the economic equivalent of one share of Issuer Class A common stock.
6. The Reporting Person has elected to defer payment on such incentive units until the earlier of (i) the retirement or termination of the Reporting Person, or (ii) a change in control of Issuer.
7. Includes 73 incentive units acquired on March 19, 2026 and 128 incentive units acquired on May 28, 2026.
