 the fair value of our RSUs is based on the stock price on the day immediately preceding the date of grant, there will no longer be a significant level of judgment involved that could impact the fair value of the RSUs or expense incurred.

Performance-Based Restricted Stock Units

In July 2023, we granted PRSUs to each of our three founders (“Founder PRSUs”). In October 2023, we granted 28,571 additional PRSUs as part of a hiring grant to an executive under the 2023 Plan. These and the Founder PRSUs will vest upon the satisfaction of a service condition and the achievement of certain stock price goals. We estimate the grant date fair value of PRSUs using a model based on multiple stock price paths developed through the use of a Monte Carlo simulation that incorporates into the valuation the possibility that the stock price goals may not be satisfied. A Monte Carlo simulation model requires the use of various assumptions, including the

underlying stock price, volatility, expiration term, and the risk-free interest rate as of the valuation date, corresponding to the length of time remaining in the performance period, and expected dividend yield. The derived service period calculation also requires the cost of equity assumption to be used in the Monte Carlo simulation model. Term and volatility are typically the primary drivers of this valuation. The average grant date fair value of the Founder PRSUs were estimated to be $15.82 per share, and we will recognize total stock-based compensation expense of approximately $6.3 million over the derived service period. The weighted-average grant date fair value of the PRSUs granted in October was $5.67 per share for the 7,143 RSUs vesting upon an Average Closing Price equaling or exceeding $35 per share, $3.85 per share for the 10,714 RSUs vesting upon an Average Closing Price equaling or exceeding $70 per share, and $2.73 per share for the 10,714 RSUs vesting upon an Average Closing Price equaling or exceeding $105 per share. We will recognize total stock-based compensation expense of $0.1 million over the derived service period. If the stock price goals are met sooner than the derived service period, we will adjust our stock-based compensation expense to reflect the cumulative expense associated with the vested award. Provided that each founder/ employee individually stays employed with the Company, we will recognize stock-based compensation expense over the requisite service period, regardless of whether the stock price goals are achieved.
