11.   Earnings Per Share

​

Basic earnings per share (EPS) excludes dilution and is computed by dividing net income attributable to AECOM by the weighted average number of common shares outstanding for the period. Diluted EPS is computed by dividing net income attributable to AECOM by the weighted average number of common shares outstanding and potential common shares for the period. The Company includes as potential common shares the weighted average dilutive effects of equity awards using the treasury stock method. For the three and six months ended March 31, 2024 and 2023, equity awards excluded from the calculation of potential common shares were not significant.

​

The following table sets forth a reconciliation of the denominators for basic and diluted earnings per share:
