DEREGISTRATION OF SECURITIES

This Post-Effective Amendment (the “Post-Effective Amendment”) relates to the following Registration Statement on Form S-8 (the “Registration Statement”) filed by HireRight Holdings Corporation ( “HireRight”) with the Securities and Exchange Commission (the “SEC”):

On June 28, 2024, Hearts Merger Sub, Inc., a Delaware corporation (“Merger Sub”) and a wholly owned subsidiary of Hearts Parent, LLC, a Delaware limited liability company (“Parent”), completed its merger (the “Merger”) with and into HireRight pursuant to the terms of the Agreement and Plan of Merger, dated February 15, 2024 (the “Merger Agreement”), by and among Parent, Merger Sub and HireRight. HireRight was the surviving corporation in the Merger and, as a result, is now a wholly owned subsidiary of Parent.

As a result of the Merger, HireRight has terminated all offerings and sales of securities pursuant to the Registration Statement. In accordance with an undertaking made by HireRight in Part II of the Registration Statement to remove from registration, by means of a post-effective amendment, any of the securities that had been registered for issuance under the Registration Statement that remain unsold at the termination of such offering, HireRight hereby removes from registration all of such securities registered but remaining unsold under the Registration Statement as of the date hereof.

SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Post-Effective Amendment to the Registration Statement described above to be signed on its behalf by the undersigned, thereunto duly authorized, in Nashville, Tennessee, on June 28, 2024.

No other person is required to sign this Post-Effective Amendment in reliance on Rule 478 of the Securities Act of 1933.
