Data last updated . This count is computed from the published headquarters dataset each time the page loads. Registered-agent addresses are excluded so incorporation services do not inflate a state, a company with two listed share classes is counted once, and companies headquartered outside the United States are counted in no state. How this count is derived.

Informational purposes only — not investment advice. Headquarters locations reflect each company's most recently recorded principal address and are approximate.
