Hunterbrook Media released a research report on January 7 2026 that accuses CVS Health Corp., UnitedHealth Group Inc., and Cigna Corp. of using shell companies to divert drug‑rebate money that should be passed to patients and health plans. The report identifies three subsidiaries—Zinc (CVS), Emisar (UnitedHealth), and Ascent (Cigna)—that are incorporated in Ireland, Switzerland, and Minnesota, respectively, and are described as pass‑through entities that collect fees from drugmakers while retaining the rebates.
The report estimates that the three subsidiaries could have collected up to $2.5 billion in rebates in 2025, a figure that represents a significant portion of the PBM revenue stream. The allegations claim that the rebates, which are now required by the HHS final rule effective January 1 2026 and by state laws such as North Carolina’s SB 479, should be fully passed to health plans and patients but are instead retained by the parent companies’ own entities.
CVS Health, UnitedHealth Group, and Cigna have not issued formal statements in response to the Hunterbrook investigation. In the absence of a public denial, the companies have stated that they are unaware of any wrongdoing and have not provided evidence to support the allegations.
The allegations come at a time of heightened regulatory scrutiny of pharmacy benefit managers. The U.S. Food and Drug Administration and the Federal Trade Commission are investigating PBMs for anti‑competitive practices, and the HHS final rule on drug rebates imposes new transparency requirements. State legislation, such as North Carolina’s SB 479, further mandates that rebates be passed through to patients, creating a legal framework that could expose the alleged shell companies to enforcement action.
Market reaction to the Hunterbrook report was muted. On January 6, CVS Health’s stock closed down 0.27 % to $80.48. Analysts maintained a positive outlook, with Piper Sandler raising its price target to $101 and Bernstein increasing its target to $87, citing the company’s forward guidance and strategic initiatives. The PBM allegations add a layer of risk that could influence future analyst sentiment and investor confidence.
If the allegations are substantiated, the impact could be significant. CVS’s PBM segment accounts for roughly 30 % of its total revenue, and a diversion of rebates would reduce margin and cash flow in that segment. The reputational damage could also erode trust among health plans and patients, potentially leading to regulatory fines and a loss of market share. The company’s broader strategy of becoming a technology‑enabled health platform, which includes acquisitions such as Aetna and Oak Street Health, could be strained if PBM revenue is curtailed.
The Hunterbrook Media report represents a new, material event that could alter investor expectations and regulatory dynamics for the PBM industry. Investors should monitor subsequent developments, including any regulatory actions or company responses, to assess the long‑term implications for CVS Health and its peers.
