Note 9—Earnings Per Share

Basic earnings per common share (“EPS”) is computed by dividing net income attributable to Amphenol Corporation by the weighted average number of common shares outstanding. Diluted EPS is computed by dividing net income attributable to Amphenol Corporation by the weighted average number of outstanding common shares, including dilutive common shares, the dilutive effect of which relates to stock options. The following is a reconciliation of the basic weighted average common shares outstanding to diluted weighted average common shares outstanding, which were used to calculate the earnings per share (basic and diluted) for the three months ended March 31, 2026 and 2025:
