Stock options During the six months ended June 30, 2025, the Company granted stock options for the purchase of 2,172,150 shares of common stock with a weighted average exercise price of $2.92 per share and a weighted average grant-date fair value of $2.33 per share. As of June 30, 2025, the unrecognized compensation cost related to outstanding stock options was $21.4 million, which is expected to be recognized over a weighted-average period of 2.0 years. On March 7, 2024, the Company approved an option repricing program applicable to outstanding option awards granted to current employees of the Company under the Company’s 2020 Stock Option and Incentive Plan, or the 2020 Plan, with an exercise price per share greater than or equal to $22.00. The repriced awards have new exercise prices of $11.88 per share for awards held by employees generally and $19.00 per share for awards held by members of the Company's senior leadership team. To receive the benefit of this reduced exercise price, holders of repriced option awards must not, prior to March 7, 2025, (i) voluntarily leave employment with the Company or (ii) exercise the repriced options. The repriced options otherwise remain on their existing terms and conditions as set forth in the 2020 Plan and applicable award agreements. The Company recorded an incremental non-cash charge of $0.1 million and $0.4 million during the three months ended June 30, 2025 and 2024, respectively, and $0.3 million and $0.5 million for the six months ended June 30, 2025 and 2024, respectively, related to this option repricing. On October 7, 2024, the 2020 Plan was amended to prohibit the plan's administrator from reducing the exercise price of outstanding stock options or stock appreciation rights or effecting repricing through cancellation and re-grant or cancellation in exchange for cash or other awards without prior stockholder approval. Performance-based restricted stock units During the six months ended June 30, 2025, the Company did not grant any performance-based restricted stock units, or PSUs. In addition, no PSUs vested during the six months ended June 30, 2025 upon their respective achievement of performance-based vesting criteria. As of June 30, 2025, the remaining 98,000 of unvested PSUs have been forfeited, as the term of the performance-based vesting period expired on February 28, 2025. Time-based restricted stock units During the six months ended June 30, 2025, the Company issued 1,954,500 restricted stock units, or RSUs, that were subject to time-based vesting conditions to its employees. These RSUs are valued on the grant date using the grant date market price of the underlying shares. A total of 369,967 RSUs vested during the six months ended June 30, 2025 upon their respective vesting schedules. Upon vesting, each RSU automatically converts into one share of the Company’s common stock. The Company indirectly repurchased 48,625 shares of its common stock through net-share settlement as consideration for employee tax withholding obligations arising upon vesting of the RSUs, which tax amounts were remitted to the applicable revenue authorities by the Company in cash on behalf of the RSU holders. As of June 30, 2025, there were a total of 2,957,988 RSUs outstanding and the unrecognized compensation cost related to outstanding RSUs was $11.5 million, which is expected to be recognized over a weighted-average period of 3.2 years.
