Per Share Data

9 Months Ended

Sep. 30, 2025

Basic (loss) earnings per share is based upon the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share includes the effect of certain stock options and other equity-based compensation awards. Our unvested restricted stock units contain non-forfeitable rights to dividend equivalents and are considered participating securities. We compute basic and diluted (loss) earnings per share under the two-class method.

(Loss) earnings per share data is as follows:
