## Summary

Aon plc (AON) reported ~$15.7B revenue in FY2024. Global professional services firm providing risk, reinsurance, health, and human capital advisory. HQ: Dublin / London.

## Company Overview

Aon plc is one of the world's largest professional services firms focused on risk, reinsurance, retirement, and health solutions. Founded in 1982 and headquartered in Dublin, Aon operates across more than 120 countries, employing approximately 60,000 professionals who advise clients on managing complex risks and optimizing their human capital strategies. The company's core offering is insurance brokerage and risk advisory — Aon acts as an intermediary between corporations and insurers, placing coverage and advising on risk management programs.

Aon generated approximately $15.7 billion in revenue in FY2024, with organic revenue growth driven by strong demand for specialty risk placements, reinsurance brokerage through Aon Re, and health benefits consulting. The company's 3x3 Plan — three priorities across three segments — targets double-digit free cash flow growth through operational efficiency, cross-selling the full suite across Commercial Risk, Reinsurance, Health, and Wealth segments. Aon's scale gives it negotiating leverage with insurers and access to specialized capacity for hard-to-place risks.

Aon's aborted $30 billion merger with Willis Towers Watson (abandoned in 2021) underscored how consolidation pressure is reshaping the insurance brokerage industry. Aon has since focused on organic growth and bolt-on acquisitions, including the 2023 acquisition of NFP, a leading middle-market broker, for $13.4 billion. The NFP acquisition significantly expands Aon's presence in the U.S. middle market and adds benefits administration capabilities.

### What is the difference between Aon and an insurance company?

### What is Aon's ticker?

### What is the NFP acquisition?
In 2023 Aon acquired NFP, a leading U.S. middle-market insurance broker and benefits consultant, for $13.4 billion. The deal expands Aon's footprint with smaller and mid-sized companies that were previously underserved by Aon's large-account focus.

### What are Aon's core business lines and revenue scale?
Aon generated approximately $15.7 billion in revenue annually across three primary segments: Commercial Risk Solutions (property & casualty insurance brokerage), Reinsurance Solutions (brokering coverage for insurers), and Human Capital Solutions (health benefits consulting, HR outsourcing).

### How does Aon compete with Marsh & McLennan and Willis Towers Watson?
Aon, Marsh & McLennan (MMC), and Willis Towers Watson (WTW) are the world's three largest insurance brokers and risk advisors, controlling a large share of global commercial insurance placement. Competition centers on relationship management, specialty expertise in complex risk lines (cyber, D&O, parametric insurance), proprietary data and analytics, and global reach. Aon attempted to acquire WTW in 2020 but abandoned the deal due to antitrust concerns.

### How is Aon using data and analytics to differentiate?
Aon has invested in proprietary risk analytics platforms that model complex risk scenarios for cyber, climate, and catastrophe risk—giving clients data-driven insights to inform risk transfer decisions. Aon's Stroz Friedberg subsidiary provides cybersecurity consulting and incident response, while Aon Insights delivers benchmarking and industry risk data. These analytics capabilities are designed to move Aon from pure brokerage to a higher-value advisory and data services role.
