Footnotes (4)

[F1]The restricted stock unit shall vest 33% on the first annual anniversary of the grant; 33% on the second annual anniversary of the grant; and 34% on the third annual anniversary of the grant. Each restricted stock unit represents a right to receive one share of common stock or an amount equal to the fair market value of the common stock underlying the unit on the vesting date.
[F2]The RSUs are subject to a performance based vesting component at the end of a three-year performance period.
[F3]The conversion price of the RSUs was based on the closing price of McGrath RentCorp common stock on February 24, 2026 and therefore such date is determined to be the date exercisable.
[F4]Shares acquired upon vesting of performance based RSUs. Each vested RSU converts into 159.21% of one share of McGrath RentCorp common stock.
