Hudson Frederick M.: Director.
F1: Pursuant to the Agreement and Plan of Merger, dated as of August 1, 2026, by and among Indivior Pharmaceuticals, Inc. ("Indivior"), Artemis Merger Sub Inc. and Supernus Pharmaceuticals, Inc. ("Supernus Pharmaceuticals"), at the effective time of the merger on 11/2/26, Artemis Merger Sub Inc. merged with and into Supernus Pharmaceuticals, with Supernus Pharmaceuticals surviving as a wholly-owned subsidiary of Indivior. At the effective time, each outstanding share of Supernus Pharmaceuticals common stock was cancelled and automatically converted into the right to receive 1.5401 shares of Indivior common stock. In connection with the merger, Indivior changed its name to "Supernus, Inc." The reporting person's shares of Supernus Pharmaceuticals common stock were disposed of, and the shares of Supernus, Inc. common stock received in exchange were acquired, pursuant to the merger. The reporting person received no cash consideration other than cash in lieu of a fractional share.
F2: Each restricted stock unit represents the right to receive one share of Supernus common stock upon vesting.
F3: Pursuant to the Agreement and Plan of Merger, dated as of August 1, 2026, by and among Indivior Pharmaceuticals, Inc. ("Indivior"), Artemis Merger Sub Inc. and Supernus Pharmaceuticals, Inc. ("Supernus Pharmaceuticals"), at the effective time of the merger on 11/2/2026, each outstanding Supernus Pharmaceuticals equity award was assumed by Indivior (renamed Supernus, Inc.) and automatically converted into a corresponding Supernus, Inc. equity award covering the number of Supernus, Inc. shares equal to the number of Supernus Pharmaceuticals shares subject to the award multiplied by the 1.5401 exchange ratio (rounded down), with the per-share exercise price divided by the exchange ratio and rounded up to the nearest whole cent. Each converted award is subject to substantially the same terms and conditions, including vesting, that applied immediately prior to the effective time, except performance stock unit awards ceased were converted into time-vesting restricted stock units.
F4: These restricted stock units will be settled in common stock upon vesting, which will occur on February 18, 2027.
F5: The option vests on February 23, 2024.
F6: The option vests on February 22, 2025.
F7: The option vests on February 19, 2026.
F8: Each option vests on February 18, 2027.

Hudson Frederick M.: Director.

F1: Pursuant to the Agreement and Plan of Merger, dated as of August 1, 2026, by and among Indivior Pharmaceuticals, Inc. ("Indivior"), Artemis Merger Sub Inc. and Supernus Pharmaceuticals, Inc. ("Supernus Pharmaceuticals"), at the effective time of the merger on 11/2/26, Artemis Merger Sub Inc. merged with and into Supernus Pharmaceuticals, with Supernus Pharmaceuticals surviving as a wholly-owned subsidiary of Indivior. At the effective time, each outstanding share of Supernus Pharmaceuticals common stock was cancelled and automatically converted into the right to receive 1.5401 shares of Indivior common stock. In connection with the merger, Indivior changed its name to "Supernus, Inc." The reporting person's shares of Supernus Pharmaceuticals common stock were disposed of, and the shares of Supernus, Inc. common stock received in exchange were acquired, pursuant to the merger. The reporting person received no cash consideration other than cash in lieu of a fractional share.

F2: Each restricted stock unit represents the right to receive one share of Supernus common stock upon vesting.

F3: Pursuant to the Agreement and Plan of Merger, dated as of August 1, 2026, by and among Indivior Pharmaceuticals, Inc. ("Indivior"), Artemis Merger Sub Inc. and Supernus Pharmaceuticals, Inc. ("Supernus Pharmaceuticals"), at the effective time of the merger on 11/2/2026, each outstanding Supernus Pharmaceuticals equity award was assumed by Indivior (renamed Supernus, Inc.) and automatically converted into a corresponding Supernus, Inc. equity award covering the number of Supernus, Inc. shares equal to the number of Supernus Pharmaceuticals shares subject to the award multiplied by the 1.5401 exchange ratio (rounded down), with the per-share exercise price divided by the exchange ratio and rounded up to the nearest whole cent. Each converted award is subject to substantially the same terms and conditions, including vesting, that applied immediately prior to the effective time, except performance stock unit awards ceased were converted into time-vesting restricted stock units.

F4: These restricted stock units will be settled in common stock upon vesting, which will occur on February 18, 2027.

F5: The option vests on February 23, 2024.

F6: The option vests on February 22, 2025.

F7: The option vests on February 19, 2026.

F8: Each option vests on February 18, 2027.
