1Quantities in the following discussion are denoted in whole shares. During the quarters ended September 30, 2023 and 2022, and nine months ended September 30, 2023, approximately 4,800, 36,000 and 14,000 shares, respectively, were excluded from the weighted-average diluted shares computation as their inclusion would have been anti‑dilutive. For the nine months ended September 30, 2022, approximately 141,000 shares were excluded from the computation of net loss per share as their inclusion would have been anti-dilutive.
