Average value per unit as per Monte Carlo simulations |  |  | Prior to the Company’s IPO on August 8, 2025, the Company used a Monte Carlo simulation model and probability weighted valuations based on different scenarios including change of control, IPO and default scenarios to value the Warrants. The value per Warrant under the change of control scenario was the average value per unit under 50,000 Monte Carlo simulations, the value per Warrant under the IPO scenario was based on the number of common stock equivalent shares (including the Warrants) and total estimated equity value of the Company, and the value per Warrant under the default scenario was assumed to be zero. |  |  |
