During the nine months ended September 30, 2023, the Company granted stock options to new employees to purchase 166 thousand shares of common stock with an exercise price ranging from $6.33 to $11.60 per share, a term of 10 years, and a vesting period of 4 years. The options have an aggregated fair value of $1.0 million that was calculated using the Black-Scholes option-pricing model. Variables used in the Black-Scholes option-pricing model include: (1) discount rate range from 3.5% to 4.32% (2) expected life of 6 years, (3) expected volatility range from 80.6% to 81.6%, and (4) zero expected dividends.

 

The fair values of all options issued and outstanding are being amortized over their respective vesting periods. The unrecognized compensation expense at September 30, 2023 was $7.7 million related to unvested options, which is expected to be expensed over a weighted average of 2.7 years. During the nine months ended September 30, 2023 and 2022, the Company recorded compensation expense related to stock options of $2.4 million and $1.6 million, respectively.

The RSUs vest at the earliest of a change of control event, the termination of the recipient’s continuous service status for any reason other than by the Company for cause and the third anniversary of the date of the grant. The fair value of the RSUs, $1.8 million, was determined based on the stock prices on the dates of the grants and each RSU grant is being recognized over its respective three-year period. The unrecognized compensation expense at September 30, 2023 of $1.1 million is expected to be expensed over a weighted average of 1.9 years. During the nine months ended September 30, 2023 and 2022, the Company recorded compensation expense related to RSUs of $0.4 million and $0.1 million, respectively.
