Companies

61 entities: suppliers, integrators, operators and the acquired predecessors they absorbed. 32 carry a public ticker. Exposure is computed by rolling each build-time supplier up to the corporate parent that owns it today, which is why HPE carries Cray's and SGI's history and NVIDIA carries Mellanox's.

With system exposure

Ranked by aggregate Rmax of the systems each company supplies any part of. This is a breadth measure, not revenue and not attributable share — see the caveat on any company page.
