Net Loss per Common Share [Abstract] |
Net Loss per Common Share | Note 3. Net Loss per Common Share The following table sets forth the computation of basic and diluted loss per share (in thousands, except per share data):
|  | Three Months Ended September 30, |  |  | Nine Months Ended September 30, |
|  | 2024 |  |  | 2023 |  |  | 2024 |  |  | 2023 |

Net loss |  | $ | (5,675 | ) |  | $ | (6,841 | ) |  | $ | (17,305 | ) |  | $ | (20,395 | )

Net loss attributable to common stockholders – basic and diluted |  | $ | (5,675 | ) |  | $ | (7,056 | ) |  | $ | (17,305 | ) |  | $ | (21,041 | )

Weighted average shares used in computing net loss per common share – basic and diluted |  |  | 93,048 |  |  |  | 71,588 |  |  |  | 89,063 |  |  |  | 64,246 |
Net loss per common share – basic and diluted |  | $ | (0.06 | ) |  | $ | (0.10 | ) |  | $ | (0.19 | ) |  | $ | (0.33 | )
Net loss per share is based on the weighted average number of the Company’s common shares and common share equivalents outstanding during the period. In periods with a reported net loss, the effect of anti-dilutive stock options, unvested restricted common stock and warrants are excluded and diluted loss per share is equal to basic loss per share. Due to a net loss in the three and nine months ended September 30, 2024 and 2023, there were therefore no dilutive securities and hence basic and diluted loss per share were the same. The following is a summary of the weighted average common stock equivalents for the securities outstanding during the respective periods that have been excluded from the computation of diluted net loss per common share, as their effect would be anti-dilutive (in thousands):
|  | Three Months Ended September 30, |  |  | Nine Months Ended September 30, |
|  | 2024 |  |  | 2023 |  |  | 2024 |  |  | 2023 |
Warrants |  |  | 2,212 |  |  |  | 5,973 |  |  |  | 2,538 |  |  |  | 6,092 |
Options |  |  | 12,407 |  |  |  | 13,069 |  |  |  | 12,882 |  |  |  | 11,410 |
Unvested restricted common stock |  |  | 2,997 |  |  |  | 1,783 |  |  |  | 2,997 |  |  |  | 771 |
Total potentially dilutive shares |  |  | 17,616 |  |  |  | 20,825 |  |  |  | 18,417 |  |  |  | 18,273 |
As all potentially dilutive securities are anti-dilutive as of September 30, 2024 and 2023, diluted net loss per share is the same as basic net loss per share for each period.
