Willis Re was the global reinsurance broking and advisory division of Willis Towers Watson (WTW). With a history tracing back to 1828 through its parent company, Willis Re established itself as one of the world's largest reinsurance brokers. The firm provided a full range of transactional, advisory, and analytical services to insurance companies globally, helping them manage their risk and capital through reinsurance solutions. In December 2021, Willis Re was acquired by Arthur J. Gallagher & Co. for approximately $3.25 billion and was subsequently integrated with Gallagher's existing reinsurance operations to form a new global entity named Gallagher Re.
