Note 11 — Net Loss per Share Attributable to Common Stockholders

Basic net loss per share is
computed by dividing the net loss by the weighted-average number of common shares outstanding for the period. Because the Company reported
a net loss for the years ended December 31, 2024 and 2023, the number of shares used to calculate diluted net loss per common share
is the same as the number of shares used to calculate basic net loss per common share for those periods presented because the potentially
dilutive shares would have been antidilutive if included in the calculation.

The following table sets forth
the computation of basic and diluted net loss per share attributable to common stockholders (in thousands, except share and per share
data):

| Weighted average shares used to computing basic and diluted net loss per share |     |              | 5,604,651 |   |     |              | 5,600,741 |   |
| Net loss per share attributable to common stockholders – basic and diluted:    |     | $            |     (1.65 | ) |     | $            |     (1.84 | ) |

The following outstanding
shares of potentially dilutive securities were excluded from the computation of diluted net loss per share attributable to common stockholders
for the periods presented because including them would have been antidilutive:

|                                  |     |  Years ended 
 December 31, |            |    |     |      |            |    |
