Sandler O'Neill & Partners

Sandler O'Neill & Partners was a leading full-service investment banking firm that specialized in the financial services sector. Founded in 1988, the firm provided specialized advisory services in mergers and acquisitions, capital markets, fixed income, and equity research for banks, thrifts, and insurance companies. The firm was highly regarded for its deep expertise in the Financial Institutions Group (FIG) space. In January 2020, the company was acquired by Piper Jaffray to form Piper Sandler, creating a major mid-market investment banking powerhouse. While the original firm was not a life sciences company, its successor, Piper Sandler, maintains a significant healthcare and biotechnology investment banking practice.
