Basic net income per common share is calculated by dividing net income available to common stockholders by the weighted-average number of common shares outstanding during the reporting period.

Diluted net income per common share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted. It is computed by dividing net income available to common stockholders by the sum of the weighted-average common shares outstanding and the effect of all potentially dilutive common shares outstanding during the period.

Potentially dilutive common shares include stock options and RSAs granted under the Corporation’s share-based compensation plans. These securities are included in the diluted earnings per share calculation only when their effect is dilutive. Securities that would increase earnings per share are considered anti-dilutive and are therefore excluded from the computation of diluted earnings per share for the applicable periods.

The following tables reconcile basic and diluted net income per common share for the three and nine months ended September 30, 2026 and 2025.
