Pursuant to the terms and conditions set forth in the Merger Agreement, on April 1, 2025, Merger Sub merged with and into the Issuer (the "Merger"), with the Issuer continuing as the surviving corporation (the "Surviving Corporation").

Shalam and Mr. A. Shalam). The foregoing description of the Merger Agreement is qualified in its entirety by reference to the full text of the Merger Agreement, which is filed as Exhibit 99.1 and is incorporated herein by reference.
