The 2021 Equity Incentive Plan (the “RSL 2021 EIP”) was approved and adopted in connection with the Business Combination and became effective immediately prior to closing. As of the effective date of the RSL 2021 EIP, no further stock awards have been or will be made under the Roivant Sciences Ltd. Amended and Restated 2015 Equity Incentive Plan (the “RSL 2015 EIP”). At September 30, 2026, a total of 58,798,689 common shares were available for future grants under the RSL 2021 EIP.

In June 2026, the Company’s trailing 30-day volume-weighted average trading price per share exceeded $30.00, satisfying the share price hurdle for the sixth and final vesting tranche of PSUs granted in July 2024 and 2025 under multi-year incentive compensation arrangements for certain senior executives (the “Senior Executive Compensation Program”). As a result, the “Performance Condition” (as defined in the Senior Executive Compensation Program) was satisfied for 15,298,215 PSUs, and therefore all 43,350,000 PSUs granted under the Senior Executive Compensation Program have satisfied the Performance Condition.

Following the achievement of the Performance Condition, the PSUs remain subject to a service-based vesting condition (the “Service Condition”), which will be deemed satisfied on the first anniversary of the date on which the Performance Condition is first satisfied with respect to such tranche, subject to the executive’s continuous service through such anniversary. Subsequent to quarter-end, the Service Condition was satisfied for the first tranche of PSUs granted under the Senior Executive Compensation Program, and may be settled into common shares on one or more settlement dates following vest pursuant to the terms of the PSUs. Once both conditions are met and the PSUs are fully vested, the underlying common shares are subject to an additional two-year holding period, measured from their vesting date, before such common shares may be sold by the executive (subject to certain customary exceptions, including sales to cover applicable tax withholding payments due in connection with the settlement of the PSUs). In November 2026, the Company entered into a letter agreement with Matthew Gline, Chief Executive Officer, that allows Mr. Gline to charitably donate a certain number of net common shares issued to him on settlement of his fully vested PSUs, on or prior to December 31, 2026, to a donor advised fund. In conjunction with the donation, the two-year holding period that would otherwise be applicable to such shares is transferred to a certain number of common shares underlying certain of Mr. Gline’s vested stock options previously granted to Mr. Gline on April 20, 2022, as specified in the agreement.

Certain subsidiaries of RSL adopt their own equity incentive plan (“EIP”). Each EIP is generally structured so that the applicable subsidiary and its affiliates’ employees, directors, officers, and consultants are eligible to receive non-qualified and incentive stock options, stock appreciation rights, restricted share awards, RSUs, and other share awards under their respective EIP. The Company recorded share-based compensation expense of $14.0 million and $28.8 million for the three and six months ended September 30, 2026, respectively, and $14.4 million and $33.7 million for the three and six months ended September 30, 2025, respectively, related to subsidiary EIPs.
