Open-market activity splits into 7 purchases totalling €6.7M and 9 sales totalling €6.1M; 1 insider sit on the buying side and 1 insider on the selling side. Purchases outweigh sales by €607k. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Among those who bought: 1 senior executive. The largest single trade was a sale of €2.3M by Zeidel Darren, published on 7 November 2025.
The last purchase on record was published on 3 September 2026, which is 44 days ago. Filings reach the SEC (Form 4) feed a median of 4 days after the trade. Section 16 rules allow two business days to file each Form 4. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning.

The full history, which starts in 2016, counts 15 purchases against 29 sales.

About Aon plc
Aon plc is a global professional services firm listed on the NYSE/NASDAQ in the United States (United States) and widely regarded as one of the leading international brokers and advisors in insurance, risk management, reinsurance, and human-capital solutions. Aon describes itself as being “in the business of better decisions,” which captures the company’s integrated model: it helps clients make better choices across risk, health, retirement, and workforce strategy. The firm serves clients in more than 120 countries, giving it broad geographic diversification and exposure to a wide range of industries. ([aon.com](https://www.aon.com/about-us?utm_source=openai))
Aon’s business is organized around two major client needs: Risk Capital and Human Capital. Risk Capital includes broking and risk transfer, claims management, reinsurance, risk analytics, risk management, and risk retention. Human Capital covers health and benefits, human capital analytics, investments, pensions and retirement, talent and rewards, and workplace wellbeing. This structure is important for investors because it shows Aon’s emphasis on advisory-led, data-driven, and relatively asset-light services rather than balance-sheet-heavy insurance underwriting. The company’s model is designed to monetize recurring demand for advice and placement services, while deepening relationships with large corporate, institutional, and public-sector clients.

From a competitive standpoint, Aon holds a strong position in a global market that is highly competitive but concentrated among a few large brokers and advisory firms. Its scale, worldwide footprint, specialized industry expertise, and analytics capabilities help differentiate it from smaller peers. Aon also highlights solutions tailored to sectors such as financial institutions, healthcare, industrials, insurance, retail, technology, transportation, and real estate. For investors, this matters because Aon’s revenue base is linked to structural needs: insurance complexity, cyber exposure, climate and catastrophe risk, pension de-risking, employee benefits inflation, and evolving compensation and talent issues. ([aon.com](https://www.aon.com/en/about?utm_source=openai))
Historically, Aon’s roots go back through decades of consolidation in insurance brokerage and advisory services, eventually forming a global platform with a long operating history and a reputation for specialist advice. While the company does not market itself as a traditional insurer, it plays a central role in the insurance value chain, connecting clients with carriers, reinsurers, and capital solutions while also advising on people strategy. That dual capability is one of its key strengths and helps support cross-selling across risk and people mandates. ([aon.com](https://www.aon.com/en/about?utm_source=openai))
Recent company communications in 2025 show continued focus on retirement transactions in the UK, digital asset capabilities in EMEA, and advisory offerings for growing businesses. Aon also pointed to attractive bulk annuity pricing conditions and continued innovation in the UK pension risk-transfer market, while highlighting infrastructure and digital-risk themes in its research and commentary. Taken together, these developments reinforce Aon’s positioning as a global, client-led advisory platform with exposure to long-duration risk, retirement, and workforce trends rather than a single-product insurer.
