The transaction, led by Carlyle AlpInvest, represents a significant realization event for TowerBrook Fund V and is a strong endorsement of EisnerAmper’s long-term growth potential
NEW YORK — MARCH 25, 2026 — TowerBrook Capital Partners L.P. (“TowerBrook”) today announced the completion of a continuation vehicle (“CV”) transaction in connection with its investment in Eisner Advisory Group LLC (“EisnerAmper”), a leading accounting, tax, outsourcing, and business advisory firm serving middle-market clients and HNWIs across the U.S. The transaction provides optional liquidity to existing investors while enabling TowerBrook to continue its successful partnership with EisnerAmper. Carlyle AlpInvest led the transaction, with funds managed by Hamilton Lane serving as co-lead alongside participation from syndicate investors.
As a result of a carefully developed thesis in Professional Services with the increasing relevance of technology and consolidation trends, TowerBrook partnered with EisnerAmper in 2021 in what was the first major private equity partnership with a top 20 U.S. accounting firm. Since then, the firm has worked closely with management to drive transformational growth, significantly scaling its platform and capabilities through a combination of organic initiatives, strategic acquisitions and continued investment in talent, technology, and advisory services.
With TowerBrook’s support, EisnerAmper has completed 27 add-on acquisitions and made meaningful investments in its technology platform and AI capabilities to enhance operating efficiency and client service delivery. EisnerAmper has also expanded its offerings within higher-value advisory services, including fund administration, outsourcing and wealth management, while continuing to deepen its core tax and assurance capabilities. Today, EisnerAmper offers a broad and diversified suite of services and has established a strong competitive position among super regional firms. Since the partnership began, EisnerAmper has grown to become the 13th largest accounting firm in the U.S., with more than $1.2 billion in revenue.
The transaction marks a significant realization for TowerBrook Fund V, delivering liquidity to investors and EisnerAmper partners while underscoring confidence in the company’s performance and long-term outlook. It also positions the firm for its next phase of growth, with a focus on further scaling its platform, expanding service capabilities, advancing technology and AI initiatives, and executing on a robust pipeline of strategic acquisitions.
Walter Weil, Managing Director at TowerBrook, commented, “Our original investment thesis for the accounting sector proved to be true. Yet without the right partner, realizing the opportunity behind that thesis would have been impossible. Our collective focus with management on key value drivers has entirely been centered on improving the day-to-day of the amazing partners at EisnerAmper, and through that focus ultimately ensuring the highest quality of service for our clients. While we have accomplished much in our first four-plus years, the long-term opportunity continues to be as compelling as ever, and we’re excited to continue our partnership with EisnerAmper as we build toward our goal of creating an end-to-end conduit of professional services for middle- and lower-middle-market companies.”
Jonathan Bilzin, Managing Partner, Co-CEO at TowerBrook, added, “Our partnership with EisnerAmper reflects our strategy of collaborating with leading businesses to accelerate growth and build scaled, differentiated and technology-enabled platforms. EisnerAmper is a clear example of that approach in action. We are excited about the progress achieved alongside Charly and the management team and remain confident about the opportunity ahead as we continue to support the firm in its next chapter.”
Charly Weinstein, CEO of EisnerAmper, commented, “Our partnership with TowerBrook has been transformational in helping us expand the business and broaden the solutions we deliver to clients. As we look ahead, with TowerBrook’s continued support, we remain focused on evolving our platform by investing in our people, enhancing our capabilities and leveraging innovation to meet our clients’ increasingly complex needs.”
Michael Hacker, Partner at Carlyle AlpInvest, said, “This transaction reflects our focus on investing in market-leading companies. In partnership, TowerBrook and EisnerAmper have built a differentiated business, and we’re pleased to support them in the next phase of growth.”
