Basic EPS is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the applicable period. Diluted EPS is computed by dividing income by the weighted-average number of shares of common stock outstanding, increased by incremental shares that would be outstanding if potentially dilutive non-participating securities were converted to common stock as calculated using the treasury stock method. EPS for the periods were:

As there was a Net Loss Attributable to Stockholders, the computation of diluted EPS excludes 138,886 RSUs and 619,525 PSUs for the three and six months ended June 30, 2026. Diluted EPS for the three months ended June 30, 2025 excludes 83,347 PSUs due to their anti-dilutive nature. As there was a Net Loss Attributable to Stockholders for the six months ended June 30, 2025, the computation of diluted EPS excludes 266,938 RSUs and 2,166,138 PSUs.
