| Earnings Per Share | 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. The computation of diluted loss per share for the three months ended June 30, 2026 excludes approximately 2.0 million potential common shares due to their antidilutive effect. For the three months ended June 30, 2025, equity awards excluded from the calculation of potential commons shares were 0.2 million shares. For the nine months ended June 30, 2026 and 2025, equity awards excluded from the calculation of potential common shares were 0.2 million and 0.4 million shares, respectively. The following table sets forth a reconciliation of the denominators for basic and diluted earnings per share:
