CamberView’s deep experience and expertise in shareholder and governance matters significantly expands our ability to serve clients. CamberView shares a commitment to integrity, collaboration and best-in-class client service, which is at the heart of our firm.”

Under the terms of the acquisition agreement, the Company will acquire 100% ownership of CamberView in exchange for total consideration of approximately $165 million, comprised of approximately $100 million of equity in a combination of Class A common stock and partnership units and $65 million of cash, subject to net working capital and other adjustments as set forth in the agreement.

Abe M. Friedman, Chief Executive Officer and a founder of CamberView, said, “We are excited to become a part of PJT Partners, which will enable us to provide our clients access to a fuller suite of advisory capabilities. PJT Partners shares an intense focus on providing the highest integrity client service and our mutual commitment to an entrepreneurial culture of collaboration will ensure a smooth transition and enhance our service to clients.”

This combination brings together

two businesses with proven track records of successfully advising blue chip companies globally. Corsair is looking forward to becoming a shareholder in PJT Partners.”
