For the three months ended September 30, 2025 and 2024, the Company recognized a total of $253,000 and $400,000 in stock-based compensation expense, respectively. For the nine months ended September 30, 2025 and 2024, the Company recognized a total of $1,044,000 and $1,715,000 in stock-based compensation expense, respectively. The Company recognizes stock-based compensation over the vesting period, which is generally within three years for both the restricted stock units and stock options.
