Note 9 — Earnings Per Share

Basic earnings per share is calculated by dividing net income by the weighted-average shares of common stock outstanding during each period, excluding non-vested restricted shares. Our diluted earnings per share is based on the weighted-average shares of common stock outstanding during each period plus the maximum dilutive effect of common stock issuable upon exercise of stock options or vesting of restricted stock units. Stock options and unvested restricted stock units are considered common stock equivalents and are only included in the calculation of diluted earnings per common share when their effect is dilutive.

The following table sets forth the computation of basic and diluted earnings per common share for the three and six months ended June 30, 2026 and 2025:
