12. Net Income (Loss) per Common Share

Basic net income or loss per share attributed to common stockholders is calculated by dividing the net income or loss attributed to Fortress, including the Series A Preferred dividends and subsidiary deemed dividends, by the weighted-average number of shares of Common Stock outstanding during the period, not including unvested restricted stock and other potentially dilutive securities. Diluted net income (loss) per share of common stock includes the effect, if any, from the potential exercise or conversion of securities, such as warrants, stock options, restricted stock units, and restricted stock using the treasury stock method, if dilutive. The impact of these items is anti-dilutive during periods of net loss. 

For the three months ended June 30, 2025 and 2024, the effect on the net income (loss) per share calculation from Series A Preferred dividends (paid and cumulated but undeclared) (see Note 13) was $2.0 million and $2.0 million, respectively, and partner company preferred and deemed dividends were $0.1 million and $0.4 million, respectively. For the six months ended June 30, 2025 and 2024, the effect on the net income (loss) per share calculation from Series A Preferred dividends (paid and cumulated but undeclared) (see Note 13) was $4.0 million and $4.0 million, respectively, and partner company preferred and deemed dividends were $0.2 million and $0.8 million, respectively.

The following potentially dilutive securities would be excluded from the computation of net loss per common share as of the dates presented if the Company was in a net loss position:
