Willis Towers Watson posts 4% organic revenue growth and margin expansion in Q3 2026

Willis Towers Watson reported third‑quarter 2026 results with 4% organic revenue growth year‑over‑year and a 150‑basis‑point expansion in adjusted operating margin to 21.9%. Adjusted diluted earnings per share rose 18% to $3.63, while total revenue reached about $2.46 billion. The company highlighted progress on its Propel AI acceleration plan, which incurred $7 million in cash costs and generated $18 million of annualised run‑rate savings during the quarter.

The margin expansion improves the firm’s profitability outlook and supports its target of roughly 30% adjusted operating margin by 2028, according to the company’s presentation. However, the Willis Re joint‑venture is expected to drag adjusted EPS by $0.30 for 2026, a cost disclosed in the earnings release.
