Other Events

As previously disclosed, on March 1, 2020, Mobile Mini, Inc., a Delaware corporation (“Mobile Mini” or the “Company”), WillScot Corporation, a Delaware corporation (“WillScot”), and Picasso Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of WillScot (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) pursuant to which, subject to the satisfaction or waiver of certain customary closing conditions, Merger Sub will be merged with and into Mobile Mini, with Mobile Mini surviving as a wholly-owned subsidiary of WillScot (the “Merger” or the “Proposed Transaction”). On May 21, 2020, the Company received notice from the United States Federal Trade Commission of early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, in connection with the Merger.

Important Information About the Proposed Transaction

In connection with the Proposed Transaction, WillScot filed a registration statement on Form S-4 (No. 333-237746), which includes a prospectus of WillScot and a joint proxy statement of WillScot and Mobile Mini (the “joint proxy statement/prospectus”). The registration statement was declared effective by the SEC on May 5, 2020, and WillScot and Mobile Mini commenced mailing the joint proxy statement/prospectus on or about May 8, 2020. Each party will file other documents regarding the Proposed Transaction with the SEC. No offering of securities shall be made, except by means of a prospectus meeting the requirements of Section 10 of the U.S. Securities Act of 1933, as amended. INVESTORS AND SECURITY HOLDERS ARE URGED TO READ THE JOINT PROXY STATEMENT/PROSPECTUS AND OTHER RELEVANT DOCUMENTS FILED WITH THE SEC CAREFULLY AND IN THEIR ENTIRETY, IF AND WHEN THEY BECOME AVAILABLE, BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION THAT STOCKHOLDERS SHOULD CONSIDER BEFORE MAKING ANY DECISION REGARDING THE PROPOSED TRANSACTION. Investors and security holders are able to obtain these documents (if and when available) free of charge from the SEC’s website at www.sec.gov. The documents filed by WillScot with the SEC may also be obtained free of charge from WillScot by requesting them by mail at WillScot Corporation, 901 S. Bond Street, Suite 600, Baltimore, Maryland 21231. The documents filed by Mobile Mini may also be obtained free of charge from Mobile Mini by requesting them by mail at Mobile Mini, Inc., 4646 E. Van Buren Street, Suite 400, Phoenix, Arizona 85008.

WillScot, Mobile Mini, their respective directors and executive officers and other members of management and employees and certain of their respective significant stockholders may be deemed to be participants in the solicitation of proxies in respect of the Proposed Transaction.
