DEREGISTRATION OF UNSOLD SECURITIES

These Post-Effective Amendments relate to the following Registration Statements (collectively, the “Registration Statements”) of Cision Ltd. (the “Company”):

On January 31, 2020, Castle Merger Limited (“Merger Sub”), a Cayman Islands exempted company with limited liability and a wholly-owned subsidiary of the Castle Acquisition Limited (f/k/a MJ23 UK Acquisition Limited, “Parent”), a private company limited by shares incorporated in England and Wales merged (the “Merger”) with and into the Company. The Merger was pursuant to the Agreement and Plan of Merger (the “Merger Agreement”) entered into on October 22, 2019, by and among the Company, Parent and Merger Sub. The Company continued as the surviving company and a wholly-owned subsidiary of Parent.

As a result of the consummation of the transactions contemplated by the Merger Agreement, the Company has terminated all offerings of its Ordinary Shares pursuant to its existing registration statements, including the Registration Statements. Accordingly, pursuant to the undertaking contained in the Registration Statements to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering, the Company is filing these Post-Effective Amendments to the Registration Statements to deregister all the shares of the Company’s Ordinary Shares registered under the Registration Statements, which remained unissued as of the effective time of the Merger. Each Registration Statement is hereby amended, as appropriate, to reflect the deregistration of all such Ordinary Shares.

As no securities are being registered herein, and the sole purpose of this filing is to terminate and deregister securities, the exhibit disclosure requirements under Item 601 of Regulation S-K are inapplicable to this filing.
