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.

Footnote F2

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.
