Basic net income (loss) per share was computed using the weighted-average shares of common stock outstanding during the period.

Diluted net income (loss) per share was computed using the weighted-average shares of common stock and, if dilutive, the potential common stock outstanding during the period. Potential shares of common stock consist of the incremental common stock issuable upon the exercise of stock options and vesting of restricted stock units. The dilutive effect of outstanding stock options and restricted stock units is reflected in diluted earnings (loss) per share by application of the treasury stock method.

We had 447,981 and 403,145 options to purchase common stock for the three-month periods ended June 30, 2026, and 2025, respectively, and 436,396 and 434,520 options to purchase common stock for the six-month periods ended June 30, 2026, and 2025, respectively, that were excluded from the diluted net income (loss) per share computation because their inclusion would have been anti-dilutive. Performance-based stock option awards were not included in the computation since the applicable conditions had not been satisfied. We had 28,266 and 79,339 restricted stock units for the three-month and six-month periods ended June 30, 2026, respectively, excluded from the computation of diluted net loss per share because their effect would have been anti-dilutive.
