Aon plc (NYSE: AON), a global professional services and insurance brokerage firm headquartered in Dublin with approximately 50,000 employees, generated $11.1 billion in revenue in FY2020. The company's adjusted operating margin was 28.5%, solid but constrained by a fragmented operational structure inherited from decades of acquisitions. Back-office systems, technology infrastructure, and operational processes were siloed across Aon's four solution lines — Commercial Risk Solutions, Reinsurance Solutions, Health Solutions, and Wealth Solutions. Client-facing teams operated largely independently, limiting cross-selling and creating duplicative processes. In July 2021, the $30 billion combination with Willis Towers Watson was terminated, resulting in a $1 billion break fee and an 800 basis point hit to reported operating margin that year. The failed merger refocused management attention squarely on organic growth and internal efficiency.
Starting in 2021, Aon accelerated two interconnected transformation initiatives — Aon United and Aon Business Services — to consolidate operations and drive margin expansion:
Maximus — Digital Government Services Expansion Driving Revenue Growth in Benefits Administration
- **Revenue growth**: Revenue grew from $4
Loomis AB — Margin Expansion Through Cash Management Automation and Service Bundling
- **Record revenue**: Full-year 2024 revenue reached SEK 30
