What Cardinal Health, Inc. told the SEC could break it.

Cardinal Health's revenue rides on a very short list of buyers: its five largest customers (CVS Health among them, at 30%) made up 43% of fiscal 2025 revenue, and sales through its two largest group-purchasing organizations, Vizient and Premier, added up to another 27%. The other heavy weight in its register is litigation — the multi-year National Opioid Settlement Agreement plus $56 million accrued for IVC-filter product-liability suits. Around those sit supply-and-product risks: roughly $491 million of direct commodity exposure (oil-based resins, nitrile, cotton, diesel, latex), certain components from sole suppliers, and an FDA warning letter over China-sourced plastic syringes that lacked 510(k) clearance.

6 self-disclosed vulnerabilities, pulled from its own filings — each in the company’s words, with the source. This is the risk register almost nobody reads.

In its own words

What could break it.

Customer concentration

  • five largest customers = 43% of revenue; Vizient + Premier GPOs = 27%high

    Beyond CVS (30%), Cardinal Health's sales/credit concentration is significant: its five largest customers account for 43% of fiscal 2025 revenue, and sales to members of its two largest GPOs (Vizient and Premier) collectively account for 27%.

    In the aggregate, our five largest customers, including CVS Health, accounted for 43 percent of our fiscal 2025 revenue. We have agreements with group purchasing organizations (“GPOs”) that act as agents to negotiate vendor contracts on behalf of their members. Our two largest GPO relationships in terms of revenue are with Vizient, Inc. and Premier, Inc. Sales to members of these two GPOs, under numerous contracts across our businesses, collectively accounted for 27 percent of our revenue in fiscal 2025.

Commodity & input dependence

  • oil-based resins, nitrile, cotton, diesel fuel, latex (~$491M annual exposure)medium

    Cardinal Health is directly exposed to price changes in oil-based resins, nitrile, cotton, diesel fuel, and latex used in medical products, with ~$491M of forecasted direct commodity exposure for fiscal 2026.

    We are directly exposed to market price changes for certain commodities, including oil-based resins, nitrile, cotton, diesel fuel, and latex. We typically purchase raw materials at either market prices or prices tied to a commodity index and some finished goods at prices based in part on a commodity price index.

Regulatory & policy

  • FDA warning letter — China-sourced plastic syringes (510(k) clearance)medium

    Following a Dec 2023 inspection, the FDA issued an April 2024 warning letter over plastic syringes sourced from a third-party China manufacturer lacking appropriate 510(k) clearance; Cardinal took action and continues to cooperate.

    For example, following a facility inspection in December 2023, the FDA issued a warning letter to Cardinal Health in April 2024 related to plastic syringes sourced from a third party manufacturer in China asserting these products did not have appropriate 510(k) clearance and restating some of the observations from the December 2023 inspection.

Sole-source dependency

  • certain components and raw materials from a sole supplier (unnamed)medium

    For reasons of quality assurance, cost effectiveness, or availability, Cardinal Health procures certain components and raw materials from a sole supplier, exposing it to interruption if those relationships are disrupted.

    In some instances, for reasons of quality assurance, cost effectiveness, or availability, we procure certain components and raw materials from a sole supplier. Our supplier relationships could be interrupted, become less favorable to us or be terminated and the supply of these components, compounds, raw materials, or products could be interrupted or become insufficient.
