Performance-Based Stock Option Activity

During 2024, the Company granted performance-based stock options ("PSOs") to the executive leadership team.

Fair value was estimated using the Black-Scholes option-pricing model. Total grant-date fair value of the PSOs was $0.3 million. As of March 31, 2025, the unrecognized stock-based compensation cost of unvested PSOs was $0.1 million, which is expected to be recognized by the end of 2025.
