[Form 4] WD 40 CO Insider Trading Activity

Rhea-AI Filing Summary

WD-40 Company director Edward O. Magee, Jr. received a restricted stock unit (RSU) award covering 612 shares of the company’s common stock on December 12, 2025, granted under the Directors’ Compensation Policy and Election Plan adopted on June 16, 2025. The RSU grant had an aggregate fair market value of approximately $125,000 on the grant date and represents the non-elective portion of annual director compensation, which vests immediately upon grant.

The RSU balance was adjusted downward by 8 units to correct an error in last year’s reported RSU awards, and vested RSUs will be settled in WD-40 Company common stock after his service as a director ends.
