Grant Thornton Advisors LLC and Grant Thornton Ireland to Combine

10.24.24

Simpson Thacher is representing Grant Thornton Advisors LLC (“Grant Thornton Advisors”) and New Mountain Capital in connection with the announced combination of Grant Thornton Advisors with Grant Thornton Ireland’s advisory and tax businesses. Grant Thornton Ireland is a leading audit, tax and advisory services provider in Ireland. The transaction is the first announced by Grant Thornton Advisors since New Mountain Capital’s growth investment in May 2024. In the months since that partnership was finalized, Grant Thornton has accelerated execution of its business strategy with investments in client solutions, service quality, technology and talent. Financial terms of the transaction were not disclosed.

Following the closing of the transaction, which is expected to occur in the first calendar quarter of 2025, Grant Thornton Ireland will operate in an alternative practice structure. Grant Thornton Ireland’s attest business will continue as an independent partnership under the alternative practice structure. Grant Thornton Advisors is a US-based tax and advisory services provider operating in an alternative practice structure alongside Grant Thornton LLP, a licensed certified public accounting firm that provides audit and assurance services.

The Simpson Thacher team included Ben Schaye, Stephen Powell, Simon Teich and Matt Nolan (M&A); Andrew Purcell and Adam Hersch (Tax); Andrew Blau, Linda Barrett and Hannah Daniels (Executive Compensation & Employee Benefits); Lori E. Lesser (Intellectual Property); Peter Guryan and Étienne Renaudeau (Antitrust); Christopher Brown, Benjamin Persina, Janhvi Barthwal and Alexandra Cullen (Finance & Credit); Abram J.
