TowerBrook Capital Partners has completed a continuation vehicle transaction for Eisner Advisory Group, the business consulting and accounting firm known as EisnerAmper, allowing the private equity firm to retain ownership while delivering liquidity to existing investors and partners.
The transaction was led by Carlyle AlpInvest, with funds managed by Hamilton Lane serving as co-lead alongside additional syndicate investors. The deal represents a significant realization event for TowerBrook Fund V while signaling continued conviction in the long-term growth prospects of EisnerAmper.
TowerBrook first invested in EisnerAmper in 2021 in what was one of the earliest private equity partnerships with a top 20 U.S. accounting firm. Since then, the firm has driven substantial expansion through a combination of organic growth initiatives, strategic acquisitions, and investments in talent and technology.
During the holding period, EisnerAmper completed 27 add-on acquisitions and expanded its capabilities across advisory, outsourcing, wealth management, and fund administration. The firm has also invested in its technology platform and AI capabilities to improve efficiency and client service. As a result, EisnerAmper has grown into the 13th largest accounting firm in the United States, generating more than $1.2 billion in revenue.
The continuation vehicle provides optional liquidity to existing investors while enabling TowerBrook Capital Partners to continue supporting the company’s next phase of growth. That next phase is expected to focus on scaling the platform further, expanding service offerings, advancing technology and AI initiatives, and executing additional acquisitions.
Support: Advisors on the transaction included Moelis as lead financial advisor, Deutsche Bank as co-lead financial advisor, Kirkland & Ellis as legal advisor to TowerBrook, and Dechert as legal advisor to EisnerAmper.
