Hunterbrook Media released a short‑seller research report on January 7 2026 that accuses Cigna Group of operating a network of shell companies—most notably the subsidiary Ascent—to siphon billions of dollars in pharmacy‑benefit‑manager (PBM) rebates away from patients and health plans and into the insurer’s own pockets. The report claims that Ascent, a group purchasing organization (GPO) with minimal physical presence in Ireland and Switzerland, collects fees from drug manufacturers while presenting itself as a pass‑through entity that delivers 100 % of rebates to plan sponsors.
The report details how Ascent’s structure allows Cigna to retain a portion of the rebates that would otherwise be returned to health plans. According to Hunterbrook, the GPO’s revenue is largely generated from manufacturer fees, and the company’s contracts with health plans include language that the GPO will pass through all rebates. By operating Ascent as a separate legal entity, Cigna can keep a share of the rebate money before it reaches the plan sponsor, effectively shifting funds from the plan to the insurer’s balance sheet.
Cigna has not yet issued a formal response to the allegations. In the days following the report’s release, the company declined to comment on the claims and did not provide any statements to the media or regulators. The lack of a public rebuttal leaves the allegations unchallenged and increases uncertainty for investors and regulators alike.
The allegations come amid heightened scrutiny of the PBM industry. The Federal Trade Commission has previously sued major PBMs, including Cigna’s Express Scripts, over opaque rebate practices. While no formal investigation has yet been announced specifically targeting Ascent, the report’s timing—just weeks after Cigna announced a transition to a rebate‑free pharmacy model—raises questions about the company’s compliance with its own transparency commitments and could prompt new regulatory inquiries.
Market reaction to the report has been muted in terms of trading activity, but investor sentiment has shifted toward caution. Analysts have noted that the allegations could erode confidence in Cigna’s PBM operations, a core revenue driver for its Evernorth Health Services segment. The potential for regulatory action and the possibility of financial penalties add a layer of risk that investors are now weighing against the company’s recent earnings performance.
The allegations also cast doubt on Cigna’s recent “rebate‑free” initiative, which was positioned as a move toward greater transparency and upfront discounts. If the shell‑company structure is proven to exist, it would suggest that the company has been retaining rebate revenue under the guise of a pass‑through model, undermining the credibility of its public commitments and potentially affecting future pricing negotiations with drug manufacturers and health plans. The outcome of any regulatory review or legal action could materially alter Cigna’s cost structure and profitability in the PBM space.
