In connection with the proposed Business Combination, the Company filed a registration statement on Form S-4 (File No. 333-220356) (the “Registration Statement”) with the SEC, which includes a proxy statement/prospectus that is both the proxy statement to be distributed to holders of the Company’s ordinary shares in connection with the Company’s solicitation of proxies for the vote by the Company’s shareholders with respect to the Business Combination and other matters described in the Registration Statement, as well as the prospectus relating to the offer and sale of certain of the securities to be issued in the Business Combination. After the Registration Statement is declared effective, Double Eagle will mail a definitive proxy statement/prospectus and other relevant documents to its shareholders as of the Record Date. The Company’s shareholders and other interested persons are advised to read the preliminary proxy statement/prospectus included in the Registration Statement and the amendments thereto and the definitive proxy statement/prospectus, when available, as these materials will contain important information about Williams Scotsman, the Company and the Business Combination.
