2.Quantities in the following discussion are denoted in whole shares. For the years ended December 31, 2024 and December 31, 2023, approximately 1,100 and 35,000 shares, respectively, were excluded from the weighted-average diluted shares computation as their inclusion would have been anti-dilutive. For the year ended December 31, 2022, approximately 139,000 potentially dilutive shares were excluded from the computation of net loss per share as their effect would have been anti‑dilutive.
