Schedule of Key Assumptions Used In Estimating the Fair Value of SARs

The following table summarizes the key assumptions used in estimating the fair value of the SARs at issuance and on September 30, 2025:

			July 7, 2025						September 30, 2025
Expected term (years)			1-2.90						0.90-2.80
Risk-free interest rate			4.17%-4.38%						3.79%-4.11%
Stock price volatility			85%-115%						85%-115%
Probability (1)			50%-50%						50%-50%
Dividend rate			—		%				—		%

(1) Scenario probability was based on timing expectations of the Company that a corporate transaction occurring was estimated at 50%; and a corporate transaction not occurring at 50%.

The following are the underlying assumptions used in the Black-Scholes-Merton option pricing model to determine the fair value of stock options granted to employees and to non-employees under this stock plan:
