Mr. Urquhart will start at Coatue in the coming months and will get involved in key management responsibilities, according to the letter, which confirmed an earlier Bloomberg News report. He will also oversee investor relations and fundraising efforts.
Mr. Urquhart was on Carlyle's leadership and operating committees. He joined in 2019 after about 11 years at Oz Management.
A Coatue spokesman declined to comment.
Carlyle said in a statement that David McCann has been appointed interim head to replace Urquhart, who will stay at the firm through year-end. Mr. McCann joined Carlyle in 2014 and is responsible for building partnerships with the firm's largest limited partners across North America. A Carlyle spokeswoman declined to comment on the firm's plans for finding a permanent replacement for Mr. Urquhart.
Coatue is led by Philippe Laffont, who started the hedge fund in 1999 after working at Julian Robertson's Tiger Management. It managed about $59 billion as of Dec. 31.
Mr. Urquhart's departure follows the unexpected resignation of Carlyle CEO Kewsong Lee on Sunday.
Mr. Urquhart's departure is not related to that of Mr. Lee, said the spokeswoman. "Nathan's departure a situation of getting a great job," she said.
Mr. Gozycki, who's based in Washington, is set to join Capitol Meridian as a partner, said one of the people, all of whom asked not to be identified because the appointment isn't yet public. He joined Carlyle in 2007 and worked on growth, middle-market and large-cap technology investments, his LinkedIn profile shows. He was involved in the firm's bets on companies including CNSI, Net Health and Unison Software.
A Carlyle representative confirmed Mr. Gozycki exited in July and declined to comment further. A Capitol Meridian representative declined to comment.
Mr. Palmer left Carlyle last year after roughly 25 years at the firm, where he was head of its global aerospace, defense and government services team. Mr. Coburn, still a senior adviser to Carlyle, stepped down from his full-time role as deputy chief investment officer of the firm's real assets segment at the end of last year. Like Mr. Palmer, he joined the firm in 1996.
Last month, Capitol Meridian teamed up with Declaration Partners, backed by David Rubenstein's family office, and 22C Capital to acquire LMI's for-profit subsidiary.
