[1] Figures in the table may not recalculate exactly due to rounding. Earnings per share is calculated based on unrounded numbers.

[2] (b)Includes shares related to share-based compensation that vested but were not yet issued.

[3] (c)Due to the antidilutive effect of the net loss from continuing operations for the three months ended March 31, 2025, basic weighted-average common shares outstanding was used to calculate basic and diluted earnings per share. During the three months ended March 31, 2025, there were 2.7 million in share-based awards excluded because their inclusion would have been antidilutive.
