Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following at the end thereof: Consummation of Merger On September 3, 2026, the merger (the "Merger") contemplated by the Agreement and Plan of Merger (the "Merger Agreement"), dated June 18, 2026, among Andor LLC ("Parent"), a Delaware limited liability company and a wholly owned subsidiary of AbbVie Inc. ("Guarantor"), Andor Merger Co. ("Merger Sub"), a Delaware corporation and a wholly owned subsidiary of Parent, the Company and Guarantor (solely for limited purposes), was consummated. Pursuant to the Merger Agreement, Merger Sub was merged with and into the Company, with the Company surviving the Merger as a wholly-owned subsidiary of Parent. At the effective time of the Merger (the "Effective Time"), each share of Common Stock and Non-Voting Common Stock owned by the Reporting Persons immediately prior to the effective time of the Merger was cancelled and converted into the right to receive $135.11 per share in cash, without interest (the "Merger Consideration"). Each stock option owned by the Reporting Persons (whether vested or unvested) immediately prior to the Effective Time was canceled and converted into the right to receive the excess of the Merger Consideration over the exercise price payable per share under such stock option. Accordingly, as a result of the Merger, the Reporting Persons no longer beneficially own any securities of the Company. In addition, immediately prior to the Effective Time, each of the Company's directors, including Mr. Kiselak, resigned from, and ceased serving on, the Company's board of directors.
