Oppenheimer & Co.

Founded in 1881, Oppenheimer & Co. began as a family-run brokerage and has grown into a global financial institution serving individuals, families, corporations and institutions. The firm is not tied to a single family fortune but acts as a publicly accountable RIA and broker-dealer, structured to provide independent advice rather than manage one family's wealth. Oppenheimer's strategy spans wealth management, capital markets and investment banking. Wealth management offers customized financial planning and access to traditional and non-traditional products. Capital Markets focuses on financing, trading and research for municipalities, institutions and mid-market companies. Investment Banking provides strategic advisory and capital markets solutions for emerging-growth and middle-market clients. The firm maintains a US footprint through branch offices and a Chicago office, and its research arm — led by Chief Investment Strategist John Stoltzfus — covers market strategy and sector themes. The firm reports $143.3B in assets under administration as of December 31, 2025, and a book value per share of $93.81. It employs 924 financial professionals across US branch offices. A recent press release (May 2026) announced the expansion of industrials research capabilities with the addition of Brent Thielman. Oppenheimer's structural differentiator is its long-standing independent broker-dealer model — it answers only to clients rather than a controlling shareholder, a posture maintained since 1881. This independence shapes its advisory and capital markets businesses, which focus on mid-market and emerging-growth companies rather than the largest corporate clients.
