STIFEL, NICOLAUS & COMPANY, INCORPORATED

CRD#: 793 / SEC#: 801-10746, 8-1447

RIA

Registered Investment Advisory firm - SEC (5/7/1975 Approved)

Georgia

Registered Investment Advisory firm - SEC (11/30/2011 Terminated)

Broker-Dealer Firm Regulated by FINRA (Kansas City district office)

Why is a state registration marked "Terminated"? When a firm registers with the SEC (usually after managing $100M+ AUM), it often withdraws separate state firm registrations unless required by that state. The firm can still serve clients there through its individually registered Investment Advisor Representatives (IARs).
