As of June 30, 2026, total unrecognized compensation expense related to market-based stock options amounted to $98.3 million. The unrecognized expense for the stock options is expected to be recognized over a weighted-average period of 3.3 years, subject to continued vesting.

The Company takes into consideration many factors in determining the fair value of the market-based stock options and estimates the fair value of such awards on the grant date. The Company used a Monte Carlo Simulation Model (a binomial lattice-based valuation model) to estimate the fair value of the market-based stock options with the following assumptions as of June 30, 2026:

Expected term in years - The expected term is based on the average period the market-based stock options are expected to remain outstanding, generally calculated as the midpoint of the market-based stock options’ remaining vesting term and contractual expiration period, as the Company does not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior.

Volatility - The expected volatility is based on the volatility of peer companies, as there is limited trading history for the Company’s common stock. Management believes this is the best estimate of the expected volatility over the expected life of the market-based stock options.

Risk-free rate - The risk-free interest rate is based on the U.S. Treasury yield curve that corresponds with the expected term at the time of grant.

Dividend yield - The Company has not paid and does not expect to pay dividends. Consequently, the Company uses an expected dividend yield of zero.
