DEREGISTRATION OF SECURITIES

This Post-Effective Amendment relates to the following Registration Statements on Form S-8 (each, a “Registration Statement,” and collectively, the “Registration Statements”) of Sterling Check Corp., a Delaware corporation (“Sterling”), filed with the Securities and Exchange Commission (the “SEC”), to deregister all shares of Sterling’s common stock, par value $0.01 per share (“Common Stock”), remaining unsold or otherwise unissued under the relevant Registration Statement:

On October 31, 2024, pursuant to and subject to the terms of the previously announced Agreement and Plan of Merger, dated as of February 28, 2024 (the “Merger Agreement”), by and among First Advantage Corporation (“First Advantage”), Sterling, and Starter Merger Sub, Inc., a Delaware corporation and an indirect, wholly-owned subsidiary of First Advantage (“Merger Sub”), Merger Sub merged with and into Sterling, with Sterling surviving the merger with Merger Sub and becoming an indirect, wholly-owned subsidiary of First Advantage (the “Transaction”). In accordance with the terms of the Merger Agreement, outstanding equity awards granted under Sterling’s equity plans related to the Registration Statements were treated in the manner described in the Merger Agreement.

In connection with the closing of the Transaction, Sterling has terminated all offerings of its securities pursuant to its existing registration statements under the Securities Act of 1933, as amended, including the Registration Statements. In accordance with undertakings made by Sterling in the Registration Statements to remove from registration, by means of a post-effective amendment, any of the securities that had been registered for issuance that remain unsold at the termination of the offering, Sterling hereby removes from registration all of such securities of Sterling registered but unsold under the Registration Statements, if any. Each Registration Statement is hereby amended, as appropriate, to reflect the deregistration of such securities.
