Basic earnings per share is computed using the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed using the weighted-average number of common shares outstanding during the period, plus the dilutive effect of outstanding options, using the treasury stock method and the average market price of the Company’s common stock during the applicable period. Certain shares related to some of the Company’s outstanding employee share awards were excluded from the computation of diluted earnings per share because they were antidilutive in the periods presented but could be dilutive in the future. Performance-based market condition share awards are considered contingently issuable shares, which would be included in the denominator for earnings per share if the applicable market conditions have been achieved, and the inclusion of any performance-based market condition share awards is dilutive for the respective reporting periods.

For the years ended December 31, 2025, 2024 and 2023, unvested performance-based market condition share awards were excluded from the calculation of diluted earnings per share because the market conditions had not been met. There were no 7% Series A Redeemable Convertible Participating Preferred Stock shares outstanding at December 31, 2025. These preferred stock shares were anti-dilutive for the years ended December 31, 2025, 2024 and 2023 and are therefore excluded from the diluted loss per common share calculation.
