[1] For 2024, the dilutive effect of common stock equivalents was excluded from the calculation of diluted EPS because the Corporation reported a net loss and the inclusion would have an anti-dilutive effect. For 2023 and 2022, weighted average anti-dilutive common stock equivalents represent share-based compensation awards not included in the calculation of common shares outstanding for purposes of calculating diluted EPS as the grant prices were greater than the average market price of Bancorp’s common stock, and therefore were anti-dilutive.
