6. Net Loss Per Share

The Company uses the two-class method to compute basic earnings per share. Under this method, earnings are allocated to common shares and participating securities according to their participation rights in dividends declared and undistributed earnings and divide the income available to each class by the weighted average number of common shares for the period in each class. Unvested restricted stock grants made to our non-employee directors and certain employees are considered participating securities because the shares have the right to receive non-forfeitable dividends. Because the participating shares have no obligation to share in net losses, we do not allocate losses to our common shares in this calculation.

Diluted earnings per share reflect the potential dilutive effect of securities that could share in our earnings. Restricted stock awarded to non-employee directors and certain employees that have not yet vested are considered when computing diluted earnings per share. The Company uses the treasury stock method to determine the dilutive effect of unvested restricted stock. Shares of unvested restricted stock under a stock-based compensation arrangement are considered options for purposes of computing diluted earnings per share and are considered outstanding shares as of the grant date for purposes of computing diluted earnings per share even though their exercise may be contingent upon vesting. Those stock-based awards are included in the diluted earnings per share computation even if the non-employee director and employee may be required to forfeit the stock at some future date, or no shares may ever be issued to the non-employee director and/or employee. Unvested restricted stocks are not included in outstanding common shares in computing basic earnings per share.

Warrants to purchase 678,875 shares of common stock of the Company were outstanding as of December 31, 2025. Options and warrants to purchase 826,375 shares of common stock of the Company were outstanding as of December 31, 2024. There were 380,730 and 436,863 restricted shares of common stock unvested as of December 31, 2025 and 2024, respectively. These warrants and unvested restricted shares were not included in the computation of diluted earnings per share for the periods where the Company generated a net loss due to being anti-dilutive.
