Humana Inc. on May 16 said it had established a second joint venture with Welsh, Carson, Anderson & Stowe (WCAS) to further expand its value-based primary care clinics. (Hg Capital Partners and WCAS share control of MMIT, the parent of AIS Health.) The new JV will provide up to $1.2 billion of additional capital for the development of approximately 100 new CenterWell Senior Primary Care Clinics between 2023 and 2025, said Humana. The expansion follows an earlier JV that is currently deploying up to $800 million of capital to open 67 clinics by early 2023 and support their ongoing operations, added the insurer. WCAS will have majority ownership of the JV, while Humana will own a minority stake.
