4. Net Loss Per Common Share

 

Basic and diluted net loss per common share is determined by dividing net loss attributable to common stockholders by the weighted-average common shares outstanding during the period. For all periods presented, the common shares underlying the preferred stock, options, warrants, and restricted stock have been excluded from the calculation because their effect would be anti-dilutive. Therefore, the weighted-average shares outstanding used to calculate both basic and diluted loss per common share are the same.

 

The following table summarizes the potentially-dilutive shares excluded from the diluted weighted-average shares outstanding:

 

   2024   2023 
   December 31, 
   2024   2023 
Potentially-dilutive shares excluded from diluted weighted-average shares outstanding:          
Preferred stock on an as-if-converted to common stock   3,175,770    8,541,340 
Options to purchase common stock   4,306,977    2,815,392 
Warrants to purchase common stock   5,521,152    7,263,733 
Restricted common stock   1,079    1,958 
Total   13,004,978    18,622,423 

 

Pre-funded warrant shares of 5,747,787 are included in the computation of basic and diluted net loss per share for the years ended December 31, 2024 and 2023, as the pre-funded warrants are issuable for nominal consideration.
