Each card carries a disclosed-size chip (HIGH / MEDIUM / LOW — how large the exposure is as a share of revenue, not how dangerous it is) and a nature tag: Built-in(the company’s own model, geography, or products) or Outside party (an external customer, supplier, or distributor it relies on).

Personalis' concentration profile is layered and substantial across geography, customers, and suppliers. Revenue is heavily domestic, with the United States accounting for 90% of the total — a structural characteristic of the business rather than a counterparty risk. On the customer side, the top five customers represented 62% of revenue, with Moderna at 22%, the VA MVP at 17%, and Natera at 8% individually — each a comparatively modest share on its own, but together a meaningful block of dependency risk. Notably, this concentration has already proven volatile: the top five figure fell from 81% the prior year, and Natera's share dropped sharply from 30% to 8%, showing customer mix here can swing quickly. Layered on top is a supply-side dependency: Illumina is the sole supplier of sequencers, associated reagents, and related maintenance services, with no disclosed alternative. Taken together, the customer concentration is the most idiosyncratic and volatile exposure, the geographic concentration is a structural backdrop, and the Illumina dependency is the one supply-chain single point of failure that could disrupt operations independent of demand.
