("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.
