Stifel Financial Corp generates revenue through multiple channels including commissions from agency transactions in OTC and listed equity securities, insurance products, options, and mutual fund distribution fees.

Other income includes investment gains and losses, rental income, and loan origination fees. The company serves individual investors, corporations, municipalities, and institutions across its business lines.
