143 RSUs will vest when the Average Closing Price equals or exceeds $35 per share, (ii) 10,714 RSUs will vest when the Average Closing Price equals or exceeds $70 per share, and (iii) 10,714 RSUs will vest when the Average Closing Price equals or exceeds $105 per share.The Company estimated the grant date fair value of the PRSUs based on multiple stock price paths developed through the use of a Monte Carlo simulation model. A Monte Carlo simulation model also calculates a derived service period based on the expected time

to achieve the defined stock price target, as described above. 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. For Founder PRSUs, an expiration term of 5 years (as defined in the grant agreements) was utilized. A volatility of 71.0 percent was determined, based on an established peer group over the maximum term to expiration. The weighted-average grant date fair value of the Founders PRSUs was $15.82 per share. The Company will recognize total stock-based compensation expense of $6.3 million over the derived service period of 2.1 years as the founders satisfy the service-based vesting condition.For the PRSUs granted in October 2023, an expiration term of 5 years (as defined in the grant agreements) was utilized. A volatility of 71.0 percent was determined, based on an established peer group over the maximum term to expiration. The weighted-average grant date fair value of the PRSUs 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. The Company will recognize total stock-based compensation expense of $0.1 million over the derived service period of 2.6 to 3.6 years as the employee satisfies
