Basic earnings per share ("EPS") is computed using the two-class method. The deferred stock units ("DSUs") related to our stock-based compensation plan contain non-forfeitable rights to dividends and are considered as participating securities. The two-class method requires an allocation of earnings to all securities that participate in dividends with common shares to the extent that each such security may share in the Company's earnings. Basic EPS is then calculated by dividing undistributed earnings allocated to common stock by the weighted average number of common shares outstanding for the period. Under the two-class method, the impact of these participating securities was immaterial for the three and six months ended June 30, 2026 and 2025.

Diluted EPS is calculated by applying the two-class method for participating securities and then incorporating the dilutive effect of other potential common shares, determined using methods such as the treasury stock method, to arrive at the most dilutive EPS.
