MINI Mobile Mini Inc

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 28, 2020, the Company, WillScot and Merger Sub entered into an amendment to the Merger Agreement (the “Amendment”). The Amendment, among other things: (i) sets forth that the name and ticker symbol of WillScot, as of the effective time of the Merger, shall be “WillScot Mobile Mini Holdings Corp.” and “WSC,” respectively, (ii) approves, consistent with the determination by the Compensation Committee of WillScot’s Board of Directors and as permitted by WillScot’s 2017 incentive award plan, as amended from time to time (the “Incentive Plan”), that the Merger will be deemed a “Change of Control” pursuant to the Incentive Plan with respect to any unvested awards outstanding thereunder as of immediately prior to the effective time of the Merger which were granted to WillScot’s executive officers and certain other senior management team members (the “Subject Awards”), (iii) provides for the conditional redemption of all of Mobile Mini’s outstanding 5.875% senior notes due July 1, 2024, and (iv) corrects certain typographical errors contained in the Merger Agreement and provides written consent to certain actions as required by the Merger Agreement.

With respect to clause (ii) above, the Amendment would have the effect of allowing the acceleration of previously issued equity awards to WillScot employees who experience a qualifying termination within one year of the Merger. There would be no acceleration of equity awards for WillScot employees who do not experience a qualifying termination. Any exercise or settlement of the Subject Awards in respect of any such qualifying termination in connection with the Merger shall be exercised or settled only in shares of common stock of WillScot, after giving effect to the Merger, and not in cash.

The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Amendment, a copy of which is filed as Exhibit 2.1 hereto and incorporated herein by reference.
