Piper Sandler is in discussions about a potential acquisition of Perella Weinberg Partners, a transaction that would combine two Wall Street investment banking firms with significant merger and acquisition advisory businesses, according to The Wall Street Journal. The potential combination comes amid stronger U.S. dealmaking activity and continued consolidation across the investment banking industry.
Piper Sandler currently has a market capitalization of approximately $5 billion, while Perella Weinberg Partners is valued at roughly $1.4 billion. A transaction could be finalized soon, although discussions remain ongoing and there is no guarantee that the companies will ultimately reach an agreement.
A combination would substantially expand Piper Sandler’s advisory platform by adding Perella Weinberg’s relationships with large corporations, financial sponsors, institutional investors, and other clients involved in complex strategic transactions.
Piper Sandler traces its current structure to the 2020 combination of Piper Jaffray and Sandler O’Neill & Partners, bringing together two investment banks with established franchises advising small and middle-market companies. The company is led by CEO Chad Abraham and generated approximately $1.9 billion in revenue last year.
Perella Weinberg Partners was founded in 2006 by Joseph Perella, Peter Weinberg, and Terry Meguid and built its business around independent strategic and financial advice. The firm became publicly traded in 2021 through a combination with a special purpose acquisition company. Andrew Bednar became CEO in 2023 after Peter Weinberg stepped down from the position.
The firm has participated in some of the largest transactions in recent years, including advisory roles related to BlackRock’s $12.5 billion acquisition of Global Infrastructure Partners and its $12 billion acquisition of HPS Investment Partners. Those assignments demonstrate Perella Weinberg’s presence in large, complex transactions despite its smaller overall scale relative to Wall Street’s largest banks.
Perella Weinberg has also been expanding its own advisory capabilities through acquisitions. Earlier in 2026, the firm agreed to acquire U.K.-based advisory business Gleacher Shacklock, while in 2025 it agreed to acquire secondary advisory firm Devon Park Advisors. The company previously acquired energy-focused investment bank Tudor Pickering Holt in 2016.
Financial performance at Perella Weinberg has been mixed. The firm’s revenue declined from a record $878 million in 2024 to approximately $750 million in 2025, although revenue increased 1% year-over-year in its most recent quarter.
The potential transaction is emerging during a recovery in U.S. mergers and acquisitions. U.S. M&A volumes have increased approximately 33% so far in 2026 compared with the same period in 2025, according to Dealogic data cited by The Wall Street Journal. An improving deal environment can benefit advisory firms through higher transaction fees and increased demand for strategic advice.
For Piper Sandler, acquiring Perella Weinberg could provide additional scale in advisory services while expanding the firm’s exposure to larger and more complex transactions. Perella Weinberg would bring a roster of senior dealmakers, corporate relationships, and experience advising on major strategic transactions, complementing Piper Sandler’s established presence in middle-market investment banking.
The potential combination would also bring together firms with somewhat different histories and market positioning. Piper Sandler has developed a broader investment banking platform through organic expansion and combinations such as the Sandler O’Neill transaction, while Perella Weinberg was established as an independent advisory firm built around senior banker relationships and strategic advice.
Investors reacted quickly to the report. Perella Weinberg shares climbed more than 10% after news of the talks emerged, while Piper Sandler shares fell around 5% in the initial reaction, reflecting contrasting market responses to the possibility of an acquisition.
The companies have not announced definitive transaction terms, including a purchase price, consideration structure, financing arrangements, or expected closing date. The discussions could still end without an agreement.
