Through 2021, Willis Towers Watson (WTW) operated as one of the three largest global insurance brokers and advisory firms, having been formed from the 2016 merger of Willis Group and Towers Watson. The company generated approximately $8.9 billion in revenue in 2022 across two segments: Health, Wealth & Career (benefits consulting, retirement, compensation) and Risk & Broking (insurance brokerage, reinsurance). Following the abandoned merger with Aon in July 2021, WTW faced margin pressure: full-year 2022 revenue was $8.9 billion with an adjusted operating margin of approximately 20.9%. The failed merger had distracted management for over a year, and the company's back-office operations remained fragmented across legacy Willis Group and Towers Watson systems — duplicate technology platforms, inconsistent processes, and redundant support functions across geographies. Free cash flow in 2022 was $674 million, constrained by operational inefficiency.
In late 2021, WTW launched a multi-year Transformation program targeting $300 million in cumulative cost savings and 300 basis points of margin improvement by fiscal year 2024:
The program progressed methodically: $149 million in cumulative savings by end of 2022, $224 million by Q1 2023, $300 million by Q3 2023, and $337 million in cumulative savings by year-end 2023 — exceeding the original $300 million target.
