**Explanatory Note**

This Amendment No. 1 on Form 8-K/A ("Amendment") amends the Current Report on Form 8-K originally filed by WD-40 Company ("Company") with the Securities and Exchange Commission ("SEC") on June 4, 2026 ("Form 8-K"). This Amendment is being filed to update the disclosure under Item 5.02(c)(3) to reflect that the Company and its newly appointed principal accounting officer, Nicholas D. Giordano, have executed certain material agreements, which at the time of appointment had not been contemplated. Except as described herein, no other information in the Form 8-K is being amended or updated.

**ITEM 5.02. &nbsp;&nbsp;&nbsp;&nbsp;Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.**

On June 19, 2026, the Company and Mr. Giordano entered into two material agreements: (i) an indemnity agreement, and (ii) a change in control severance agreement, both agreements of which are substantially in the form previously approved by the Board for officers.

Both agreements become effective on June 29, 2026, which is the effective date of Mr. Giordano's appointment. The foregoing descriptions of the agreements do not purport to be complete and are qualified in their entirety by reference to the full text of the forms of agreements filed with the SEC on October 22, 2013 as Exhibit 10(d) to the Annual Report on Form 10-K, and filed on January 9, 2023 as Exhibit 10(a) to the Quarterly Report on Form 10-Q, respectively, and are incorporated by reference herein.
