Aon plc was founded in 1982 by the merger of Ryan Insurance Group and Combined Insurance Company of America. The initial name of this newly founded company was aon which was renamed after several years. Its new name was Aon. The founders of Aon are Pat Ryan and W. Clement Stone. Pat Ryan was the owner of Ryan Insurance Group and W. Clement Stone was the owner of Combined Insurance Company.

The mother of W. Clement Stone bought and started operating a small insurance company. In 1918, her son joined that insurance company. The company was very small and they only offered few services at that time. They were operating from only one branch and their customer base was also very narrow. After a year, in 1919, W. Clement Stone founded his own insurance company under the name Combined Registry Co.

In 1929, The Great Depression started. Combined Registry Co. reduced the workforce and started more focusing on productivity to save their expenses. Stone in 1939, bought Casualty Insurance Co. which was based in Dallas, Texas. From the 1940s to the 1960s, the company kept growing and they also expanded their services. Combined Registry Co. grew a lot during this time. They also introduced their services internationally however, the economic recession was a huge problem for the company.

Patrick Ryan was the son of a Ford dealer in Wisconsin. He started Ryan Insurance Group as an automobile insurance company in 1964. Ryan’s company bought the insurance brokerage of Esmark conglomerate in 1976. Ryan’s focus was to grow his company by introducing more and more helpful and innovative insurance services. So, he started reducing the expenses of the company. After this, the company merged with Combined Registry Co.

In 1982, Combined Insurance merged with Ryan Insurance Group to form a new insurance company. After the merger, the control of the new company was in the hand of Patrick Ryan. In 1987, Ryan changed the company’s name to Aon. Aon sold its direct life insurance holdings to General Electric to focus more on consultation services.

It was the right time for the company to introduce its services overseas and for this purpose, Aon started acquiring other small international insurance companies. They bought Alexander and Alexander Services and Minet Group in 1997. This made Aon the largest insurance brokerage in the world.

In 2000, Aon bought the accident and health insurance business of Reliance Group. They also bought Actuarial Sciences Associates. At the end of 2000, Aon tried to restructure the company and they also reduced their workforce. In 2001, Aon became a publicly-traded company. After a year, most of the insurance holdings of Aon were bought by Endurance.

Aon acquired Hewitt Associates in 2010 for $4.9 billion. This was the largest acquisition of Aon. However, this purchase made Aon a very profitable company. They made $3 billion in revenue with Hewitt Associates. Then, in 2012, the headquarters of Aon were shifted from Chicago to London. Eric Anderson became the president of the company in 2020.

An extremist answer cannot be given to this question. The short answer would be that Aon plc stock is neither a strong buy nor a strong sell. Due to the economic recession caused by the pandemic, it has become very difficult to analyze Aon stock.

We cannot say that the company is not growing or will not grow in the future and it would also be wrong to confidently say that it will grow swiftly. It is a very unpredictable situation for any tyro investor but in this section, we are going to cover this topic thoroughly. So, you do not have to worry about it.

According to wallstreetzen.com, 7 Wall Street stock analysts gave their own opinions regarding Aon plc stock. 5 out of 7 investors agreed that this stock is not a good sell. Rather, it is a time to buy it and hold it as a long-term investment.

On the other hand, 2 out of those 7 investors did not agree with that. In their opinion, Aon stock is a strong buy. However, none of the 7 investors recommended selling Aon stock. So, this is for sure that either Aon stock is a great buy or it is a good buy according to all of those investors.

According to Govt Capital Blog, in the first quarter of 2025, the stock price of Aon plc will be priced at an average of around $980 and the highest possible price of $1,132 and lowest of $837. In the last quarter of 2026, it may touch $1500. Although, the highest prediction is $1,725 and the lowest prediction is $1,275.

In our recommendation, Aon stock is not perfect for short-term investment and one may meet some losses by investing in it on a short-term basis but if you are considering a long-term investment, you will likely find it profitable.

After the merger of Combined Insurance Company and Ryan Insurance Group, the primary focus of the new company, Aon, was to expand nationally and internationally. For this purpose, the strategy of the company was not different.

They acquired several small-scaled insurance and financial services companies to expand their services and to expand overseas. In this section, we are going to discuss some of those major acquisitions.

Aon PLC (English: /ˈeɪɒn/) is a global professional services and management consulting firm that offers a range of risk-mitigation products, including commercial risk, investment, wealth, health, human capital, and reinsurance solutions. The firm also provides data and analytics services, strategy consulting through Aon Inpoint and investment banking advisory through Aon Securities. Aon has approximately 50,000 employees across 120 countries.

Founded in Chicago by Patrick Ryan, Aon was created in 1982 when the Ryan Insurance Group merged with the Combined Insurance Company of America. In 1987, that company was renamed Aon from aon, a Gaelic word meaning "one". The company is globally headquartered in London with its North America operations based in Chicago at the Aon Center. Aon is listed on the New York Stock Exchange under AON with a market cap of $65 billion in April 2023.

W. Clement Stone's mother bought a small Detroit insurance agency, and in 1918 brought her son into the business. Mr. Stone sold low-cost, low-benefit accident insurance, underwriting and issuing policies on-site. The next year he founded his own agency, the Combined Registry Co.

As the Great Depression began, Stone reduced his workforce and improved training. Forced by his son's respiratory illness to winter in the South, Stone moved to Arkansas and Texas. In 1939 he bought American Casualty Insurance Co. of Dallas, Texas. It was consolidated with other purchases as the Combined Insurance Co. of America in 1947. The company continued through the 1950s and 1960s, continuing to sell health and accident policies. In the 1970s, Combined expanded overseas despite being hit hard by the recession.

In 1982, after 10 years of stagnation under Clement Stone Jr., the elder Stone, then 79, resumed control until the completion of a merger with Ryan Insurance Co. allowed him to transfer control to Patrick Ryan. Ryan, the son of a Ford dealer in Wisconsin and a graduate of Northwestern University, had started his company as an auto credit insurer in 1964. In 1976, the company bought the insurance brokerage units of the Esmark conglomerate. Ryan focused on insurance brokering and added more upscale insurance products. He also trimmed staff and took other cost-cutting measures, and in 1987 he changed Combined's name to Aon. In 1992, he bought Dutch insurance broker Hudig-Langeveldt. In 1995, the company sold its remaining direct life insurance holdings to General Electric to focus on consulting.

Aon built a global presence through purchases. In 1997, it bought The Minet Group, as well as insurance brokerage Alexander & Alexander Services, Inc. in a deal that made Aon (temporarily) the largest insurance broker worldwide. The firm made no US buys in 1998, but doubled its employee base with purchases including Spain's largest retail insurance broker, Gil y Carvajal, and the formation of Aon Korea.

Responding to industry demands, Aon announced its new fee disclosure policy in 1999, and the company reorganised to focus on buying personal line insurance firms and to integrate its acquisitions. That year it bought Nikols Sedgwick Group, an Italian insurance firm, and formed RiskAttack (with Zurich US), a risk analysis and financial management concern aimed at technology companies. The cost of integrating its numerous purchases, however, hammered profits in 1999.

Despite its troubles, in 2000 Aon bought Reliance Group's accident and health insurance business, as well as Actuarial Sciences Associates, a compensation and employee benefits consulting company. Later in that year, however, the company decided to cut 6% of its workforce as part of a restructuring effort. In 2003, the company saw revenues increase primarily because of rate hikes in the insurance industry. Also that year, Endurance Specialty, a Bermuda-based underwriting operation that Aon helped to establish in November 2001 along with other investors, went public. The next year Aon sold most of its holdings in Endurance.

In the late 2007, Aon announced the divestiture of its underwriting business. With this move, the firm sold off its two major underwriting subsidiaries: Combined Insurance Company of America (acquired by ACE Limited for $2.4 billion) and Sterling Life Insurance Company (purchased by Munich Re Group for $352 million). The low margin and capital-intensive nature of the underwriting industry was the primary reason for the firm's decision to divest.

This growth strategy manifested in November 2008 when Aon announced it had acquired reinsurance intermediary and capital advisor Benfield Group Limited for $1.75 billion. The acquisition amplified the firm's broking capabilities, positioning Aon one of the largest players in the reinsurance brokerage industry.

In 2010, Aon made its most significant acquisition to date with the purchase of Hewitt Associates for $4.9 billion. Aside from drastically boosting Aon's human resources consulting capacity and entering the firm into the business process outsourcing industry, the move added 23,000 colleagues and more than $3 billion in revenue.

In January 2012, Aon announced that its headquarters would be moved to London, although North American operations and jobs remained in Chicago.

On 10 February 2017, Aon announced that it was selling its employee benefits outsourcing business to private equity firm The Blackstone Group for US$4.8 billion (£3.8 billion).

In February 2020, Aon named Eric Andersen as president of Aon after co-president Michael O'Connor departed the company to pursue new opportunities. He will be reporting to Greg Case, the firm's CEO.

In June 2020, Aon announced it was planning to repay the temporary 20% pay cut from 70% of employees that was published in a statement in April 2020 regarding the COVID-19 pandemic. On 30 June 2020, Aon announced it would repay staff in full, plus 5% of the withheld amount.

In June 2020, Willis Towers Watson called its shareholders to two meetings to discuss its acquisition with Aon for August 26, 2020. It was revealed that the US Department of Justice has requested more information on the deal under antitrust rules.

Aon's New York offices were on the 92nd and 98th–105th floors of the South Tower of the World Trade Center at the time of the September 11 attacks. When the North Tower was struck by American Airlines Flight 11 at 8:46 a.m., an evacuation of Aon's offices was quickly initiated by executive Eric Eisenberg, and 924 of the estimated 1,100 Aon employees present at the time managed to get below the 77th floor before United Airlines Flight 175 crashed between Floors 77 and 85 at 9:03 a.m.

Many, however, did not manage to get beneath in the 17 minutes they had between the two impacts. As a result, 176 employees of Aon were killed in the crash or died in the fires or from smoke inhalation. At 9:59 a.m., the tower finally collapsed, killing any survivors still within, including Eisenberg and Kevin Cosgrove.

In 2004–2005, Aon, along with other brokers including Marsh & McLennan and Willis, fell under regulatory investigation under New York Attorney General Eliot Spitzer and other state attorneys general. At issue was the practice of insurance companies' payments to brokers (known as contingent commissions). The payments were thought to bring a conflict of interest, swaying broker decisions on behalf of carriers, rather than customers. In the spring of 2005, without acknowledging any wrongdoing, Aon agreed to a $190 million settlement, payable over 30 months.

In January 2009, Aon was fined £5.69 million in the UK by the Financial Services Authority, who stated that the fine related to the company's inadequate bribery and corruption controls, claiming that between 14 January 2005 and 30 September 2007 Aon had failed to properly assess the risks involved in its dealings with overseas firms and individuals. The Authority did not find that any money had actually made its way to illegal organisations. Aon qualified for a 30% discount on the fine as a result of its cooperation with the investigation. Aon said its conduct was not deliberate, adding it had since "significantly strengthened and enhanced its controls around the usage of third parties".

In December 2011, Aon Corporation paid a $16.26 million penalty to the U.S. Securities and Exchange Commission and the U.S. Department of Justice for violations of the US Foreign Corrupt Practices Act. According to the Securities and Exchange Commission, Aon's subsidiaries made improper payments of over $3.6 million to government officials and third-party facilitators in Costa Rica, Egypt, Vietnam, Indonesia, the United Arab Emirates, Myanmar and Bangladesh, between 1983 and 2007, to obtain and retain insurance contracts.

On 5 January 2007, Aon announced that its Aon Affinity group had acquired the WedSafe Wedding Insurance program.

On 22 August 2008, Aon announced that it had acquired London-based Benfield Group. The acquiring price was US$1.75 billion or £935 million, with US$170 million of debt.

On 5 March 2010, Hewitt Associates announced that it acquired Senior Educators Ltd. The acquisition offers companies a new way to address retiree medical insurance commitments.

On 12 July 2010, Aon announced that it had agreed to buy Lincolnshire, Illinois-based Hewitt Associates for $4.9 billion in cash and stock.

On 7 April 2011, Aon announced that it had acquired Johannesburg, South Africa-based Glenrand MIB. Financial terms were not disclosed.

On 19 July 2011, Aon announced that it bought Westfield Financial Corp., the owner of insurance-industry consulting firm Ward Financial Group, from Ohio Farmers Insurance Co. Financial terms were not disclosed.

On 22 October 2012, Aon announced that it agreed to buy OmniPoint, Inc, a Workday consulting firm. Financial terms were not disclosed.

On 16 June 2014, Aon announced that it agreed to buy National Flood Services, Inc., a large processor of flood insurance, from Stoneriver Group, L.P.

On 31 October 2016, Aon's Aon Risk Solutions completed acquisition of Stroz Friedberg LLC, a specialised risk management firm focusing on cybersecurity.

On 14 November 2016, Aon acquired CoCubes an online Indian Assessment firm, facilitating hiring of entry-level engineering graduates.

On 10 February 2017, Aon plc agreed to sell its human resources outsourcing platform for US$4.8 billion (£3.8 billion) to Blackstone Group L.P. (BX.N), creating a new company called Alight Solutions.

In September 2017, Aon announced its intent to purchase real estate investment management firm The Townsend Group from Colony NorthStar for $475 million, expanding Aon's property investment management portfolio.

On 9 March 2020, Aon announced its merger with Willis Towers Watson for nearly $30 billion in an all-stock deal that creates the world's largest insurance broker. As of 21 May 2020, Willis board was under probe over merger agreement with Aon. The deal was called off in July 2021.

On 3 June 2009, it was reported that Aon had signed a four-year shirt sponsorship deal with English football giant Manchester United. On 1 June 2010, Aon replaced American insurance company AIG as the principal sponsor of the club. The Aon logo was prominently displayed on the front of the club's shirts until the 2014/2015 season when Chevrolet replaced them. The deal was said to be worth £80 million over four years, replacing United's deal with AIG as the most lucrative shirt deal in history at the time.

In April 2013, Aon signed a new eight-year deal with Manchester United to rename their training ground as the Aon Training Complex and sponsor the club's training kits, reportedly worth £180 million to the club.
