In addition, the PSU provides for vesting of up to a maximum of 175% of the Target Shares depending on the timing and level of achievement of the performance criteria provided for under the PSU. On January 15, 2026, the Committee determined that certain performance criteria had been achieved, resulting in the Reporting Person's eligibility to vest up to 175% of the Target Shares subject to the PSU (such shares, the "Achieved Shares"). Accordingly, the Committee's certification on January 15, 2026 resulted in the immediate vesting of 50% of the Achieved Shares, and the remaining 50% of the Achieved Shares will vest on February 15, 2027, subject to the Reporting Person's continuous service through that date. Includes 491,096 shares of Exelixis, Inc. common stock ("Common Stock") that will be issued to the Reporting Person upon vesting of restricted stock units ("RSUs") and PSUs granted to the Reporting Person on March 31, 2025 ("One-Time Award PSUs"). Each RSU is the economic equivalent of one share of Common Stock and each One-Time Award PSU represents a contingent right to receive one share of Common Stock. Shares withheld by Exelixis, Inc. to satisfy taxes payable in connection with the vesting of the PSUs awarded on April 3, 2023, for which the Committee certified that Exelixis, Inc. had achieved certain performance criteria on January 15, 2026.
