Gunnar Wiedenfels

Operator

Gunnar Wiedenfels is the Chief Financial Officer of Warner Bros. Discovery and has been designated to become CEO of the spun-off 'Discovery Global' networks business, positioning him as one of the most consequential executives in the ongoing restructuring of legacy media. As CFO, he has been central to navigating the company's massive debt load inherited from the 2022 merger of WarnerMedia and Discovery, overseeing cost transformation initiatives, and steering the company's advertising and streaming monetization strategy at a time of profound industry disruption. Wiedenfels joined Discovery, Inc. as CFO in 2017, bringing deep experience in media finance from his prior roles at ProSiebenSat.1 Media, where he served as CFO and helped modernize the German broadcaster's digital and advertising revenue streams. His tenure at Discovery saw him manage the financial integration of major acquisitions and lay the groundwork for the eventual merger with WarnerMedia. His fluency in both traditional linear advertising economics and emerging streaming business models has made him a key voice in how large media companies balance legacy revenue with digital transformation. In the AdTech and media ecosystem, Wiedenfels is recognized for his rigorous approach to monetization strategy, his role in shaping how Warner Bros.
