Warner Chappell COO/Co-Chair Carianne Marshall Leaves Role After Seven Years

The respected music publishing executive will transition out of her role at the end of the month.

Warner Music Group announced on Monday (Sept. 21) that Carianne Marshall, the COO/co-chair of its publishing arm Warner Chappell, will transition out of her role at the end of this month “as the company streamlines its leadership structure,” according to a press release.

A company source says Marshall’s departure is part of a WMG-wide shift away from having co-chairs lead their companies. Similarly, in July, sister company Warner Records moved then-co-chair and COO Tom Corson into different role as COO of WMG.

Marshall leaves her role after a seven-year tenure. Guy Moot, the company’s CEO and co-chair, will remain as the company’s sole chair, and Marshall will remain with the company through the end of the calendar year “to ensure a seamless transition,” the press release says.

A year after starting at WCM, Marshall was joined by Moot, a British A&R executive from Sony, who took the helm as CEO and co-chair. Together, Moot and Marshall became known as a formidable leadership duo, a rarity in the music industry, bringing together Marshall’s licensing chops and Moot’s creative expertise.

Robert Kyncl, CEO of WMG, says: “Carianne has been instrumental in building Warner Chappell into the successful company it is today. She’s helped drive exceptional results that have set our songwriters and our business up for long-lasting success.

Our talented team will build upon the incredible foundation she’s put in place. We thank her for her dedication, impact and wish her the very best in her next chapter.”.
