Cencora Inc (COR)

How it makes money

Cencora books the full sale price of the medicines it resells as revenue, which is why the top line is enormous and the margin on it is very thin: $11.5 billion of gross profit on $321.3 billion of revenue in fiscal 2025. Money is made in three ways. On brand-name drugs the compensation from manufacturers is largely fee-for-service, typically negotiated as a percentage of the drug's list price, so the economics track dollars of product shipped rather than the spread. On generics, Cencora buys at scale — in part through joint purchasing arrangements — and keeps the difference between its sourcing cost and what it charges pharmacies; generics carry far lower prices but far better margins. Third, service and consulting businesses (pharmacy automation, specialty logistics, regulatory and market-access consulting) are billed as fees and carry margins unlike distribution. Because the distribution margin is measured in cents on the dollar, working capital management and volume are the levers that matter.

Revenue by segment

Pharmaceutical distribution in the United States is effectively a three-firm business, and scale is the advantage. A network of distribution centres already built, already delivering daily to tens of thousands of dispensing sites, spreads its fixed cost over a volume a new entrant could not replicate without years of capital spending and no customers to pay for it. Scale also buys generic sourcing power: the larger the purchasing pool, the better the price from generic manufacturers, and generics are where the margin sits. The counterweight is that the same scale is what lets a handful of very large customers demand most of the benefit back in price — the advantage is real but a great deal of it is competed away at the customer's end of the chain.

People take their medicines in a recession. The volume that flows through a pharmaceutical distributor is set by prescriptions written, which follow demographics, disease prevalence and drug approvals rather than GDP or consumer confidence — an ageing population and a growing share of spending going to specialty and biologic therapies push volume up steadily. What does move with something other than the cycle is the mix: a wave of expensive specialty launches, or a category like GLP-1 drugs, can swell revenue dollars far faster than gross profit, because the margin on a very expensive branded drug is a thinner slice of a bigger number. So the right way to read Cencora is that units are stable and revenue is not the same thing as earnings power.

Key risks

• Loss of a key customer, or renewal on worse terms — The company discloses that its revenue, financial position, results of operations and cash flows may suffer upon the loss, or renewal at less favorable terms, of a key customer or group purchasing organization. It separately flags that the anticipated ongoing benefits of its relationship with Walgreens and Boots may not be realized, and that a disruption in its distribution or generic purchasing arrangements with Walgreens or WBAD could adversely affect the business.
• Opioid and controlled-substance litigation and investigations — Among the uncertainties the company itself lists are the outcome of legal or governmental proceedings instituted against it and continued investigation, prosecution or suit by federal and state governmental entities and other parties over alleged violations of laws and regulations regarding opioid medications, controlled substance medications or other medications, and any related disputes.
• Brand and generic pharmaceutical pricing trends — The company identifies unfavorable trends in brand and generic pharmaceutical pricing, including the rate or frequency of price inflation or deflation, as a risk. Because compensation on brand-name products is tied to list prices and generic economics depend on the spread between sourcing cost and selling price, a change in the direction or pace of pricing feeds directly into gross profit.
• Competition and consolidation of customers and suppliers — The company cites competition and industry consolidation of both customers and suppliers, resulting in increasing pressure to reduce prices for its products and services. As pharmacy chains, health systems and manufacturers combine, the counterparties on both sides of the distributor get larger and better able to negotiate.
• Changes in the U.S. healthcare and regulatory environment — The company flags changes in the U.S. healthcare and regulatory environment, including changes that could affect vaccine and prescription drug coverage, reimbursement, pricing, distribution and contracting, as well as other regulatory changes. Distribution economics rest on how drugs are paid for, so reimbursement and pricing policy is not a background condition but an input.
• Loss or disruption of information systems — The company discloses that loss or disruption of its information systems could disrupt its operations and have a material adverse effect on its business. A distributor that ships daily to tens of thousands of sites runs on its order, inventory and routing systems; an outage is an operating failure, not just an IT one.
• International operations, geopolitics and currency — The company reports geopolitical and other risks associated with its international operations, which it says could materially adversely affect its financial position, results of operations and cash flows, and separately that it might be adversely impacted by fluctuations in foreign currency exchange rates. It also flags operational and logistical risks that might not be covered by insurance, and the risk that acquisitions or investments do not perform as expected or prove difficult to integrate.

Top customers account for 66% of revenue

Concentration here is extreme and the company says so plainly. In fiscal 2025 Walgreens and Boots together accounted for approximately 25 percent of revenue, Evernorth Health Services for approximately 13 percent, and the top ten customers, including governmental agencies, for approximately 66 percent. Walgreens and Boots also represented approximately 38 percent of accounts receivable at 30 September 2025. Two counterparties therefore sit behind well over a third of the business, and the loss of either — or a renewal on tougher terms — is the single largest swing factor the filing describes.
