Aon is proposing to buy Willis Towers Watson in an all-stock transaction that would combine the second- and third-largest insurance brokerages, Bob writes.
Why it matters: Employers hire Aon and Willis Towers Watson to help them choose health plans and pharmacy benefit managers for their workers, but the major consultants don’t always steer companies toward the best deals.
- Combining into the largest consulting house on Earth will give Aon that much more power over employers.
What’s next: The two companies don’t expect to close the deal until the first half of 2021, indicating they know antitrust regulators will be closely scrutinizing this.
