Earnings Per Share [Abstract] |
Earnings/(Loss) Per Share | Note 18 — Earnings/(Loss) Per Share Basic and diluted earnings/(loss) per share are calculated by dividing net income/(loss) attributable to WTW by the average number of ordinary shares outstanding during each period. The computation of diluted earnings/(loss) per share reflects the potential dilution that could occur if dilutive securities and other contracts to issue shares were exercised or converted into shares or resulted in the issuance of shares that then shared in the net income of the Company. At September 30, 2025 and 2024, there were 0.3 million and 0.5 million restricted time-based stock units outstanding, respectively, and 0.6 million restricted performance-based stock units outstanding for both periods presented. The Company had no time-based share options or performance-based share options outstanding at September 30, 2025 and 2024. Basic and diluted earnings/(loss) per share are as follows:
|  | Three Months Ended September 30, |  |  | Nine Months Ended September 30, |
|  | 2025 |  |  | 2024 |  |  | 2025 |  |  | 2024 |
Net income/(loss) attributable to WTW |  | $ | 304 |  |  | $ | (1,675 | ) |  | $ | 870 |  |  | $ | (1,344 | )
Basic average number of shares outstanding |  |  | 98 |  |  |  | 102 |  |  |  | 99 |  |  |  | 103 |
Dilutive effect of potentially issuable shares |  |  | — |  |  |  | — |  |  |  | 1 |  |  |  | — |
Diluted average number of shares outstanding |  |  | 98 |  |  |  | 102 |  |  |  | 100 |  |  |  | 103 |
Basic earnings/(loss) per share |  | $ | 3.12 |  |  | $ | (16.44 | ) |  | $ | 8.80 |  |  | $ | (13.11 | )
Dilutive effect of potentially issuable shares |  |  | (0.01 | ) |  |  | — |  |  |  | (0.06 | ) |  |  | — |
Diluted earnings/(loss) per share |  | $ | 3.11 |  |  | $ | (16.44 | ) |  | $ | 8.74 |  |  | $ | (13.11 | )
There were no anti-dilutive restricted stock units for the three months ended September 30, 2025. For the nine months ended September 30, 2025, 0.1 million restricted stock units were not included in the computation of the dilutive effect of potentially issuable shares because their effect was anti-dilutive. There were no anti-dilutive options for the three and nine months ended September 30, 2025. The dilutive effect of potentially issuable shares was not computed for the three and nine months ended September 30, 2024 as the Company reported a net loss within its condensed consolidated statements of comprehensive income.
