Summary
Humana has announced a strategic joint venture with BlackRock that will replace Welsh, Carson, Anderson & Stowe (WCAS) as the private equity partner in its CenterWell Senior Primary Care clinic platform, according to Modern Healthcare. Publisher reporting describes BlackRock acquiring about a $2.8 billion stake in the venture, with the arrangement operating through BlackRock's acquisition of WCAS's current interest in the joint venture.

The transaction builds on an earlier partnership between Humana's CenterWell and WCAS.

Under the original terms, Humana could acquire WCAS's interest beginning in 2028 or five years after the opening of each cohort of clinics, whichever applied.
