Neither Charlie Collier, who had a four-year run leading Roku‘s ad and platform business, nor Tubi CEO Anjali Sud will join Fox Corp. after its acquisition of Roku.

The exec departures were among several organizational updates shared with employees by Anthony Wood and Paul Cheesebrough, Co-Chairs of Fox Digital Platforms. After Friday morning’s close of Fox’s $22 billion acquisition of Roku, which Wood founded, the digital division has been set up as home to Roku, Tubi, Red Seat Ventures and other properties.

Sud, who presided over Tubi’s rise to prominence in free, ad-supported streaming, is taking on a new role outside of the company, the memo said. She will stay on in the meantime to help with the transition to Pete Distad, the former Apple exec who spearheaded the launch of flagship streamer Fox One and will now add Tubi as well as Roku subsidiary pay bundle Frndly TV to his portfolio.

“She and her team have helped take Tubi from a challenger brand to a free streaming force,” Wood and Cheesbrough wrote of Sud. “We want to thank her for her extraordinary contributions and wish her every success in her next endeavor.”

Collier became President of Roku Media in 2022 after a run as CEO of Fox Entertainment. He previously had overseen cable network AMC.

Mustafa Ozgen will succeed Wood as CEO of Roku. The streaming provider’s open platform, which Wood and Cheesbrough said is “central to its success with viewers and content partners,” will stay intact.

Ozgen will continue to lead Roku’s device, product and technology organization. In addition, he will now also oversee Fox ad tech platform AdRise, the Roku Channel, streaming services partnerships, Roku Subscriptions, subscription service Howdy, Roku Pay, and Roku brand and creative operations.

Also exiting with Collier and Sud are Chris Handman, SVP and General Counsel at Roku, and Robyn Peterson, EVP of AdRise.

Other new appointments include Mike Bidgoli, who has been promoted to president of Tubi, reporting to Distad; Frndly TV co-founder and CEO Andy Karofsky, who will join Distad’s group; and Lisa Holme, head of content for The Roku Channel. Holme will report to Distad and work closely with Adam Lewinson and the Tubi content team.

Ad sales teams across the portfolio will continue to report to Jeff Collins, President of Advertising Sales at Fox. The formidable scale of the combined ad operation was made apparent on Monday when both companies reported earnings for the July-to-September quarter. Fox’s ad revenue jumped 47% year-over-year to hit $2.1 billion, while Roku’s climbed 23% to $727.4 million.

“We won’t have every answer on Day 1,” Wood and Cheesbrough conceded in the memo. “We’ll share decisions as they’re made, be clear about what’s still open, and keep moving. Our priorities remain the same: build great products, serve our viewers and partners, and support each other.”

The memo noted that town halls are planned in San Jose and San Francisco on Monday; the Fox lot and Santa Monica on Tuesday; Austin Wednesday and New York Thursday. International town halls will follow, the company said.
