DEREGISTRATION OF UNSOLD SECURITIES

These Post-Effective Amendments (the “Post-Effective Amendments”) relate to the following Registration Statements on Form S-8 (each a, “Registration Statement” and collectively, the “Registration Statements”) filed with the Securities and Exchange Commission (the “SEC”) by SecureWorks Corp., a Delaware corporation (the “Registrant”) (note that the share numbers listed below do not take into account corporate actions taken in the interim):

On February 3, 2025, the Registrant completed the previously announced merger contemplated by the Agreement and Plan of Merger (the “Merger Agreement”), dated as of October 21, 2024, among the Registrant, Sophos Inc., a Massachusetts corporation (“Parent”) and Project Green Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”). Pursuant to the Merger Agreement, Merger Sub merged with and into the Registrant, with the Registrant continuing as the surviving corporation and becoming a wholly owned subsidiary of Parent (the “Merger”).

As a result of the Merger and the other transactions contemplated by the Merger Agreement, the Registrant has terminated any and all offerings of Class A Common Stock pursuant to the above-referenced Registration Statements. In accordance with undertakings made by the Registrant in Part II of each of the Registration Statements to remove from registration, by means of a post-effective amendment, any securities that had been registered under the Registration Statements for issuance that remain unsold at the termination of the offering, the Registrant hereby removes and withdraws from registration any and all such securities registered under such Registration Statements that remain unsold or otherwise unissued, if any, as of the date hereof, and the Registration Statements are hereby amended, as appropriate, to reflect the deregistration of such securities, and the Registrant hereby terminates the effectiveness of the Registration Statements.

The foregoing summary of the Merger Agreement, the Merger and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement.
