Private equity group holds 11.7% of AdaptHealth (AHCO) common stock

Rhea-AI Filing Summary

AdaptHealth Corp. received an updated ownership filing from One Equity Partners–affiliated entities and Richard Cashin. This Amendment No. 4 to a Schedule 13D reports that the group of “Reporting Persons” may be deemed to beneficially own 15,864,871 shares of AdaptHealth common stock.

The filing states this position represents approximately 11.7% of the company’s common stock, based on 135,914,816 shares outstanding as of February 20, 2026, as reported in AdaptHealth’s Form 10-K. The shares are directly held by OEP AHCO Investment Holdings, LLC, which is owned by several Parallel Funds managed through OEP VII General Partner, L.P. and OEP VII GP, L.L.C.

The six-member investment committee of OEP VII GP, whose majority must include Richard Cashin, exercises voting and investment discretion over the reported securities, though the filing clarifies that no Reporting Person admits beneficial ownership for any other legal purpose. The group also notes that, within the prior 60 days, they acquired AdaptHealth shares in market transactions listed in an attached exhibit.

Insights

Equity ownership and governance analyst

OEP-affiliated funds disclose an 11.7% AdaptHealth stake, signaling a sizable but routine ownership update.

The filing shows OEP AHCO Investment Holdings, LLC and related funds collectively may be deemed to beneficially own 15,864,871 AdaptHealth common shares, or about 11.7% of the class, based on 135,914,816 shares outstanding as of February 20, 2026.

Control over voting and investment decisions sits with an OEP VII GP investment committee whose majority must include Richard Cashin. This structure concentrates influence yet remains typical for private equity sponsors. The amendment also records recent market purchases over the prior 60 days, but does not quantify them in this excerpt.

Overall, the disclosure mainly refreshes ownership, entity structure, and joint filing arrangements dated March 12, 2026. It confirms a meaningful minority position that could support board-level influence, while avoiding any admission of broader beneficial ownership beyond securities law requirements.
