Siebert Financial is a small, diversified financial services firm built around its primary subsidiary, Muriel Siebert & Co. (MSCO), a discount retail brokerage with over 55 years of operating history. MSCO offers self-directed trading, margin lending, retirement accounts, and fixed income products to retail customers through an online platform, mobile app, and 13 U.S. branch offices. Beyond retail brokerage, MSCO runs a Securities Finance Group (stock borrow/stock loan), a Market Making division trading over 500 equity and fixed income products, and a Corporate Services business that helps small- and mid-cap public companies manage equity compensation plans. Siebert also operates SNXT, a robo-advisory platform, and Park Wilshire, which sells insurance products including fixed annuities and life insurance. Revenue is driven by commissions, margin interest, spreads in securities finance and market making, corporate services fees, advisory fees, and insurance commissions. Siebert is pursuing several growth initiatives: correspondent clearing for other broker-dealers and RIAs, a new Investment Banking division targeting middle-market clients, and a retail platform technology upgrade. In a notable diversification, Siebert also operates a Media, Sports and Entertainment segment through Gebbia Media, which manages music and sports talent, produces content, and recently acquired Big Machine Rock and launched Gebbia Sports to serve college and professional athletes — though this segment is nascent and not yet a material revenue contributor.
