KKR & Co. completed the $9.9 billion acquisition of Envision Healthcare Corp.

In July, the deal received U.S. antitrust clearance through the early termination of the waiting period under the Hart-Scott-Rodino Act.

Following the completion of the merger, Nashville, Tenn.-based Envision becomes a wholly owned subsidiary of funds affiliated with KKR and its shares ceased to trade on the NYSE.

In June, the investment firm had said it would acquire all outstanding shares of Envision for $46 per share in cash.

Envision provides physician-led services and post-acute care and ambulatory surgery services.
