Blackstone is exploring the sale of Clarion Events, which could be valued at approximately £2 billion ($2.6 billion). The U.S. buyout group has reportedly engaged in informal discussions with private equity firms, including CVC and KKR, and may initiate an auction process early next year. In addition to the potential sale of Clarion, Blackstone is also in advanced negotiations to acquire the healthcare consulting firm Chartis Group from Audax Group. Furthermore, Blackstone's subsidiary Legence is set to acquire engineering firm AMA Group, and the firm has recently announced a majority investment in hotel accounting software provider M3. Additionally, the owners of the World Rally Championship's commercial arm are considering a sale of the business, which could be valued at $550 million.
