Item 4 of the Original Schedule 13D is hereby amended and supplemented by adding the following at the end of Item 4: On September 26, 2025, Merger Sub merged with and into the Issuer on the terms and conditions set forth in the Merger Agreement, with the Issuer surviving the Merger as a wholly owned subsidiary of Acquiror. In connection with the completion of the Merger, each share of Common Stock was automatically cancelled, extinguished and converted into the right to receive $23.00 per share in cash, without interest. In connection with the closing of the Merger, the Issuer notified the New York Stock Exchange that the Merger had been consummated and, as a result, trading of the Issuer's Common Stock on the New York Stock Exchange was halted prior to the opening of trading on September 26, 2025 and the Issuer requested that the New York Stock Exchange file with the Securities and Exchange Commission a Form 25 Notification of Removal from Listing and/or Registration under Section 12(b) of the Act to delist and deregister the Issuer's Common Stock. The Issuer intends to file with the Securities and Exchange Commission a Form 15 suspending the Issuer's reporting obligations under Sections 13 and 15(d) of the Act.
