Share-Based Payment Arrangement [Abstract]

Schedule of Assumptions Used to Determine Fair Value of Stock Options Granted

The fair value of the stock options granted during the nine months ended September 30, 2026 and 2025 was determined using the Black-Scholes option pricing model with the following assumptions:


	September 30, 2026		September 30, 2025
Expected volatility (1)	70.5% - 77.6%		72.1% - 80.4%
Expected term (years) (2)	5.6 - 5.7		5.5 - 5.7
Risk free interest rate (3)	3.6% - 5.0%		3.7% - 4.4%
Expected dividend yield	0	%	0	%
Exercise price	$7.51 - $13.38		$6.61 - $17.70

(1) Expected volatility is calculated by utilizing the Company's historical volatility of its stock price over a period equal to the expected term.

(2) Expected term is calculated based on the Company's historical experience.

(3) Risk free interest rate is based on an interpolation of U.S. Treasury rates to reflect the expected term at the date of grant.
