As of September 30, 2026 and December 31, 2025, there is no aggregate intrinsic value of options outstanding.

As of September 30, 2026, total unrecognized compensation cost related to unvested stock options was $13.2 million, which is expected to be recognized over a weighted-average period of 1.3 years.

During the nine months ended September 30, 2026, the Compensation Committee of the Company's Board of Directors granted approximately 964 thousand stock options under the 2021 Equity Incentive Plan, including a market-based stock option award granted to the Company's Chief Executive Officer that vests upon the achievement of specified market capitalization milestones, subject to the

terms of the award. The grant-date fair value of the market-based awards was determined using a Monte Carlo simulation model. The weighted-average grant-date fair value and significant assumptions used in the valuation were as follows:

The Monte Carlo simulation model incorporates the market-based vesting conditions and estimates the probability of achieving the applicable market capitalization milestones when determining the grant-date fair value.
