Explanatory Note

This Amendment No. 3 (this “Amendment”) amends and supplements the Schedule 13D previously filed with the U.S. Securities and Exchange Commission (the “SEC”) by the Reporting Persons on March 25, 2022 (the “Existing Schedule”) related to the Common Stock of the Issuer. Information reported and defined terms used in the Existing Schedule, as amended to the date hereof (this “Statement” or “Schedule 13D”), remain in effect except to the extent that they are amended or superseded by information or defined terms contained in this Amendment. The filing of this Amendment represents the final amendment to the Schedule 13D and constitutes an exit filing for the Reporting Persons.

Item 4. Purpose of Transaction.

Item 4 of this Statement is hereby supplemented to include the following information:

On July 25, 2022, certain affiliates of the Reporting Persons consummated the transactions contemplated by that Agreement and Plan of Merger, dated as of March 25, 2022 (the “Merger Agreement”), by and among the Issuer, Camelot Return Intermediate Holdings, LLC (“Parent”), Camelot Return Merger Sub, Inc. (“Merger Sub”) and the Issuer. Upon the terms and subject to the conditions set forth in the Merger Agreement, among other things, Merger Sub will merge with and into the Issuer (the “Merger”), with the Issuer surviving the Merger. Immediately prior to the consummation of the Merger, the Reporting Persons purchased all shares of Common Shares owned by Clayton, Dubilier & Rice Fund VIII, L.P. and CD&R Friends & Family Fund VIII, L.P. at a price per share of $24.65 in cash.

Following the consummation of the Merger, the Issuer notified the New York Stock Exchange (the “NYSE”) that the Merger had been completed, and requested that the NYSE suspend trading of the Common Stock on the NYSE prior to the opening of trading on July 25, 2022. The Company also requested that the NYSE file with the SEC a notification of removal from listing and registration on Form 25 to effect the delisting of all shares of Common Stock from the NYSE and the deregistration of such shares under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). As a result, shares of the Common Stock will no longer be listed on the NYSE. In addition, the Issuer intends to file a certification on Form 15 with the SEC requesting the termination of registration of all shares of the Common Stock under Section 12(g) of the Exchange Act and the suspension of the Issuer’s reporting obligations under Section 13 of the Exchange Act with respect to all shares of Common Stock.

Item 5. Interest in Securities of the Issuer

(a)-(c) Item 5 of this Statement is hereby supplemented to incorporate by reference the information set forth in Item 4 above.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Item 6 of this Statement is hereby supplemented to incorporate by reference the information set forth in Item 4 above.

SIGNATURE

After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
