David Ellison Appoints Ynon Kreiz as Co-CEO to Lead Skydance Merger

After two years of aggressive expansion, David Ellison has appointed Ynon Kreiz, the outgoing chief executive of Mattel, as co-CEO of the new Skydance media empire. The appointment coincides with the closing of the merger between Paramount Skydance and Warner Bros. Discovery, which is scheduled for Tuesday. The combined entity, to be known simply as Skydance, will consolidate major film studios, the CBS broadcast network, premium cable assets including CNN, TNT, MTV, and BET, as well as streaming platforms Paramount+ and HBO Max.

Kreiz joins Ellison on Monday and assumes the co-CEO role upon the transaction’s completion. The partnership addresses longstanding questions regarding Ellison’s ability to manage the operational complexities of a legacy media giant. Prior to his rise, Ellison led Skydance, a production company with a relatively narrow slate of hits, primarily the “Mission: Impossible” franchise and “Top Gun: Maverick.” By August 2025, he had secured Paramount in an approximately $8 billion deal, and by April 2026, he completed the acquisition of Warner Bros. Discovery in a transaction valued at roughly $110 billion on an enterprise basis.

With three decades of experience in the media industry, Kreiz is perhaps best recognized for spearheading the cinematic success of “Barbie” in 2023. However, analysts remain divided on whether his track record sufficiently prepares him to manage the integration of such massive operations. Matthew Condon, an analyst at Citizens Bank, praised the move, stating that Kreiz’s operational background and focus on intellectual property make him well-suited to build a top-tier content platform.

In the new structure, Ellison will concentrate on long-term strategy, creative direction, technology, and capital allocation, while Kreiz will oversee daily management and the integration process. Despite the co-CEO title, some experts view his role more narrowly. Matthew Dolgin, a senior equity analyst at Morningstar, described Kreiz as effectively serving as a chief operating officer, noting that while he fills a critical void, he may not be the ideal candidate for the entire scope of the role.

Kreiz’s career includes leadership positions at Maker Studios and Endemol Group, as well as co-founding Fox Kids Group Europe. At Mattel, he inherited a struggling company with declining revenue and profitability following the Toys R Us bankruptcy. He executed significant restructuring, including eliminating stock-keeping units, rationalizing business lines, reducing the workforce by 2,200 employees, and cutting approximately $1 billion in costs. Eric Handler of Roth Capital Partners highlighted these structural improvements as key factors in Mattel’s recovery.

Nevertheless, Kreiz’s tenure at Mattel faced criticism for overemphasis on entertainment ventures at the expense of toy innovation. While “Barbie” generated $1.4 billion globally, Mattel reported only a $150 million revenue boost and a 3% increase in Barbie sales during the release year. Analyst Gerrick Johnson noted that Barbie revenue has since dropped by 22%, and Mattel’s stock price returned to pre-Kreiz levels after briefly rising. Some observers argued that Kreiz lost focus on core product development after the pandemic.

Looking ahead, the Skydance merger is expected to take two to three years to fully integrate. The company has targeted $6 billion in cost savings within three years, though Laura Martin of Needham anticipates synergies may exceed this figure. The new entity will also inherit approximately $79 billion in debt. Ellison has previously indicated plans to merge Paramount+ and HBO Max into a single streaming service, a move likely to further reduce infrastructure costs.
