Insurance Broker Aon Acquires Willis Towers Watson

Insurance brokerage Aon has agreed to merge with Willis Towers Watson in an all-stock transaction that is valued at $30 billion.


Shareholders of Willis Towers Watson will receive 1.08 Aon shares for each Willis Towers Watson share, representing a 16% premium to Willis Towers’ Friday closing share price of $199.71.

“The combination of Willis Towers Watson and Aon is a natural next step in our journey to better serve our clients in the areas of people, risk and capital,” said Willis Towers Watson CEO John Haley. “This transaction accelerates that journey by providing our combined teams the opportunity to drive innovation more quickly and deliver more value.”

Aon will own roughly 63% of the combined company, while existing Willis Towers Watson shareholders will own about 37%.

“This combination will create a more innovative platform capable of delivering better outcomes for all stakeholders, including clients, colleagues, partners and investors," said Aon CEO Greg Case. “Our world-class expertise across risk, retirement and health will accelerate the creation of new solutions that more efficiently match capital with unmet client needs in high-growth areas like cyber, delegated investments, intellectual property, climate risk and health solutions.”

Aon has a market valuation of $66.8 billion while Willis Towers Watson has a market value of $34.52 billion. The combined company will be named Aon and maintain its headquarters in London.

In its press release, Aon noted that the merger combines two highly complementary businesses into a technology-enabled global platform that is more relevant and responsive to client needs. The transaction “unites firms that share a belief in the power of data-driven insights to create new sources of client value.

The transaction is subject to the approval of the shareholders of both Aon Ireland and Willis Towers Watson, as well as other customary closing conditions, including required regulatory approvals. The parties expect the transaction to close in the first half of 2021, subject to satisfaction of these conditions.
