All references in the Original Schedule 13D and this Amendment No. 1 shall be deemed to refer to the Schedule 13D as amended and supplemented by this Amendment No. 1. Item 4 of the Original Schedule 13D is hereby amended and supplemented by adding the following at the end of Item 4: On December 11, 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 and converted into the right to receive $83.50 per share in cash, without interest. In connection with the closing of the Merger, the Issuer notified the New York Stock Exchange of the consummation of the Merger and trading of the Issuer's Common Stock on the New York Stock Exchange was halted prior to the opening of trading on December 11, 2025. The Issuer requested that the New York Stock Exchange file with the Securities and Exchange Commission a Notification of Removal from Listing and/or Registration on Form 25 under Section 12(b) of the Act to delist from the New York Stock Exchange and deregister the Issuer's Common Stock. Upon effectiveness of the Form 25, the Issuer intends to file with the Securities and Exchange Commission a Certification and Notice of Termination on Form 15 to suspend the Issuer's reporting obligations under Sections 13 and 15(d) of the Act. Item 5 of the Original Schedule 13D is hereby amended and restated in its entirety as follows: (a)-(b) As a result of the closing of the Merger as described in Item 4, the Reporting Persons ceased to beneficially own any Common Stock or to have voting or dispositive power with respect to any Common Stock.
