|                                |     | 2022 |      |     |
| Expected option term (years)   |     |      |      | 7.4 |
| Expected volatility            |     |      | 69.1 |   % |
| Risk-free rate of return       |     |      |  2.5 |   % |
| Expected annual dividend yield |     |      |      |   — |

There were no options granted during the year ended December 31, 2023. The weighted-average grant date fair value of options granted was $ 2.27per share for the year ended December 31, 2022.

Option pricing models require the input of various subjective assumptions, including the option’s expected life and the price volatility of the underlying stock. The expected stock price volatility is based on the analysis of volatilities of the Company’s selected public peer group over a period commensurate with the expected term of the options. The expected term of the employee stock options represents the weighted-average period the stock options are expected to remain outstanding and is based on the contractual terms, the vesting period and the expected remaining term of the outstanding options. The risk-free interest rate is based on the U.S. Treasury interest rates whose term in consistent with the expected life of the stock options. No dividend yield is included as the Company has not issued any dividends and do not anticipate issuing any dividends in the future.
