Basic net earnings per share applicable to common stockholders is calculated by dividing net earnings applicable to common shareholders by the weighted average shares outstanding during the period, without consideration for common share equivalents. Diluted net earnings per share applicable to common shareholders is calculated by adjusting the weighted average shares outstanding for the dilutive effect of common share equivalents outstanding for the period, determined using the treasury-stock method and the if-converted method. For purposes of the calculation of dilutive net loss per share applicable to common shareholders, stock options, and warrants are considered to be common stock equivalents but are excluded from the calculation of diluted net loss per share applicable to common shareholders, as their effect would be anti-dilutive; therefore, basic and diluted net loss per share applicable to common shareholders were the same for all periods presented.

For the three and nine months ended September 30, 2025 and 2024, 1,866,826 Pre-funded Warrants to purchase Common Shares for little to no consideration, issued in connection with the August 2023 and July 2024 private placements, were included in the basic and diluted net loss per share calculation. The following table sets forth the computation of basic and diluted net income (loss) per share attributable to common shareholders:

The following outstanding potentially dilutive Common Shares equivalents were excluded from the computation of diluted net loss per share for the periods presented because including them would have been antidilutive:
