This Current Report on Form 8-K/A (this “Amendment”) is being filed as an amendment to the Current Report on Form 8-K filed by WillScot Holdings Corporation (the “Company”) on June 8, 2026 (the “Original Form 8‑K”).

The sole purpose of this Amendment is to update disclosures made under Item 5.07, Submission of Matters to a Vote of Security Holders, in the Original Form 8-K. Except as set forth herein, no other modifications have been made to the Original Form 8-K.

Item 5.07

In accordance with this result and its previous recommendation, the Board determined that the Company intends to hold future say-on-pay votes every year until the next required vote on the frequency of such say-on-pay votes.
