LIGHTBRIDGE Corp Earnings Per Share Disclosure

Note 9. Net Loss Per Share

Basic net loss per share is computed using the weighted-average number of common shares outstanding during the reporting period, except that it does not include unvested common shares subject to repurchase or cancellation, such as the Company’s RSAs and PSAs. The participants receiving RSAs have all rights as a shareholder with respect to these shares, whether vested or unvested, including, without limitation, rights to vote the shares, receive dividends, etc. The outstanding RSAs and PSAs are included in common stock issued and outstanding, but are considered contingently issuable in the calculation of weighted-average shares outstanding for purposes of calculating basic and diluted earnings per share.

Diluted net loss per share is computed using the weighted-average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise of stock options and unvested RSAs and PSAs. For the years ended December 31, 2025 and 2024, there was no difference in the number of shares used to calculate basic and diluted shares outstanding as the inclusion of the potentially dilutive securities would be antidilutive.

The outstanding securities in the table below have been excluded from the computation of diluted weighted shares outstanding for the years noted below, as they would have been anti-dilutive due to the Company’s losses at December 31, 2025 and 2024 and also because the exercise price of certain of these outstanding securities was greater than the average closing price of the Company’s common stock.
