Regulation FD Disclosure

As previously disclosed, on January 28, 2024, WillScot Mobile Mini Holdings Corp., a Delaware corporation (“WillScot Mobile Mini” or the “Company”) entered into an Agreement and Plan of Transaction (the “Merger Agreement”) by and among Brunello Merger Sub I, Inc., a California corporation and a direct wholly owned subsidiary of the Company (“Merger Sub I”), Brunello Merger Sub II, LLC, a Delaware limited liability company and direct wholly owned subsidiary of the Company (“Merger Sub II”) and McGrath RentCorp, a California corporation (“McGrath”). The Merger Agreement provides that, upon the terms and subject to the conditions set forth therein, Merger Sub I will merge with and into McGrath (the “First-Step Merger”), with the Company surviving the First-Step Merger and, immediately thereafter, McGrath will merge with and into Merger Sub II (the “Second-Step Merger”), with Merger Sub II surviving the Second-Step Merger as a wholly owned subsidiary of the Company (and together with the issuance of the common stock of WillScot Mobile Mini as set forth in the Merger Agreement, collectively, the “McGrath Acquisition”).

The McGrath Acquisition is conditioned on, among other things, the expiration or early termination of the statutory waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), and other required regulatory approvals.

As previously disclosed, on February 21, 2024, the Company and McGrath each received a request for additional information and documentary material (the “Second Request”) the Federal Trade Commission (“FTC”) in connection with the FTC’s review of the McGrath Acquisition.

On May 29, 2024, the Company certified substantial compliance with the Second Request.

The Company and McGrath have been working cooperatively with the FTC and expect to continue to do so.
