[Form 4] MCGRATH RENTCORP Insider Trading Activity

Rhea-AI Filing Summary

MCGRATH RENTCORP Executive VP and CFO Keith E. Pratt reported multiple equity award transactions. On February 23, 2026 and February 24, 2026, he exercised or converted several restricted stock unit (RSU) awards into common shares and had shares withheld to cover taxes.

RSU conversions on these dates delivered blocks of 1,201, 3,600 and 3,070 common shares at a stated price of $0.0000 per share, reflecting equity award settlement rather than an open-market purchase. Tax-withholding dispositions totaled 3,469 shares at $113.07 and 3,859 shares at $114.48 per share.

Following these transactions, Pratt’s directly held common stock position changed through both RSU-related acquisitions and tax-driven share dispositions, with reported direct ownership after the final transaction of 54,442 common shares. Footnotes explain that certain RSUs vest over three years and that some awards include performance-based vesting and a 159.21% conversion factor per vested unit.

1. 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. The RSUs are subject to a performance based vesting component at the end of a three-year performance period. 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. Shares acquired upon vesting of performance based RSUs. Each vested RSU converts into 159.21% of one share of McGrath RentCorp common stock.
