12. Net Loss per Common Share

Basic and diluted net loss per share attributed to common stockholders is calculated by dividing the net loss attributed to Fortress (less the Series A Preferred dividends) by the weighted-average number of shares of Common Stock outstanding during the period, not including unvested restricted stock, and without consideration for other potentially dilutive securities. Diluted net loss per share is the same as the basic loss per share due to net losses in all periods.

The Series A Preferred dividends included in the net loss per share calculation include dividends paid as well as dividends cumulated (but undeclared) (see Note 13). For the years ended December 31, 2024 and 2023, the effect on the net loss per share calculation from Series A Preferred dividends was $8.0 million and $8.0 million, respectively, and deemed dividends were $1.9 million and $0.7 million, respectively.

​

The following shares of potentially dilutive securities, weighted during the years ended December 31, 2024 and 2023 have been excluded from the computations of diluted weighted average shares outstanding as the effect of including such securities would be anti-dilutive:
