Remarks: Due to the limitation on the number of transactions that can be reported on a single Form 3, this Form 3 is the first of two being filed by the reporting persons on the date hereof. Fortress Investment Group and certain of its affiliates (the "Other Fortress Entities", and together with Fortress Investment Group, "Fortress") filed a Form 3 on May 10, 2024 reporting their beneficial ownership in Issuer securities. On May 14, 2024, pursuant to an internal reorganization (the "Internal Reorganization") consummated in connection with a series of transactions involving Fortress management, Mubadala Investment Company ("Mubadala") and SoftBank Group Corp., in which Fortress management and a consortium led by Mubadala's wholly owned asset management subsidiary Mubadala Capital, indirectly acquired all of the economic interest in Fortress Investment Group (the "Mubadala Transaction"), the Reporting Persons may be deemed to have acquired beneficial ownership of the securities beneficially owned by Fortress Investment Group at the time of the Mubadala Transaction reported herein. This Form 3 represents an initial Form 3 filed by the Reporting Persons with respect to their beneficial ownership of the securities reported herein. The Other Fortress Entities have separately filed a Form 3 reporting their beneficial ownership in Issuer securities. The Reporting Persons intend to file any future required Section 16 reports jointly with the Other Fortress Entities, if applicable.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
