Sidley Adds Noted Tax Partner Greg Featherman in New York

New York – Sidley is pleased to announce that Greg Featherman has joined the firm’s Tax practice as a partner in Sidley’s office in New York. He was previously a Tax partner at Weil, Gotshal & Manges LLP in New York. Earlier in his career, Mr. Featherman spent 10 years at KPMG LLP.

Mr. Featherman advises clients on the U.S. tax aspects of complex domestic and cross-border transactions. His practice focuses on transactional tax planning across a broad range of corporate and financial matters, including mergers and acquisitions, spin-offs and other divisive transactions, internal restructurings, financings, joint ventures, and strategic business formations. Mr. Featherman represents public and private companies, private equity sponsors, sovereign wealth funds, foreign pension funds, and financial institutions in acquisitions and dispositions, debt and equity investments, and other transformative transactions. He spends a considerable amount of time advising foreign funds, including sovereign wealth funds and foreign pension funds, on investments in U.S. companies.

“Greg has strong relationships with both domestic and foreign-fund clients and is particularly adept at managing tax considerations in cross-border work,” said Yvette Ostolaza, Sidley’s Management Committee Chair. “This continues our strategy of bringing on new partners that have previously worked with our partners and clients and have a strong cultural fit with Sidley.”

“With deep cross-border tax experience and drawing on his early career at a prominent global accounting firm, Greg is a strong addition to our New York office,” said Nancy Chung, managing partner of the New York office and a member of the firm’s Management Committee and Executive Committee. “Working closely with partners across practices, Greg will help clients navigate business across jurisdictions.”

Our team combines deep industry knowledge and technical excellence with a practical perspective to provide clients with tax services in multiple jurisdictions.
