The resulting company represents one of the broadest and most capable full-service investment banking platforms on Wall Street complemented by one of the largest securities distribution and trading franchises with market-leading research aligned to serve the middle-market.

“The Piper Sandler combination is an exciting milestone in our 125-year history,” said Chad Abraham, chairman and chief executive officer of Piper Sandler. “The firm will continue our unwavering commitment to clients by delivering exceptional guidance and advice. This is what differentiates us in the marketplace.”

The merger brings together Sandler O’Neill’s leadership in providing advice and solutions to clients in the financial services industry with the growing Piper Jaffray investment banking platform. Jon Doyle, former senior managing principal at Sandler O’Neill, now leads Piper Sandler’s financial services group.
