August 27, 2025
Warner Bros. Discovery Aug. 27 announced that Brad Singer will assume the role of CFO of Warner Bros. upon completion of the company’s planned separation, which is expected to occur by mid-2026.

Singer, who previously served as CFO at Discovery Communications, will report to CEO David Zaslav and future president and CEO of Warner Bros.
Singer will oversee Warner Bros.’ global financial functions and strategies, including accounting, internal audit, treasury, tax, procurement, and investor relations activities. He will begin in this new position in October 2025 in a strategic role until the official formation of Warner Bros.
Current WBD CFO Gunnar Wiedenfels is slated to become CEO of the company’s TV network assets spin-off, which includes CNN, TBS, TNT, and Discovery+, among other channels.
“Brad was instrumental in driving significant value creation and growth during our time together at Discovery Communications, and I’m thrilled to be reuniting with a trusted leader whose financial expertise and strategic vision have consistently delivered results,” Zaslav said in a statement.
Singer most recently served as COO of ValueAct Capital before retiring in 2021, during which time he also served on the boards of Rolls-Royce Holdings and Motorola Solutions.
Before joining ValueAct Capital in 2012, Singer, who was CFO of Discovery Communications, played a key role in taking the company public in 2008. He was also the CFO and treasurer of American Tower Corp., where he helped lead post-IPO growth, capital planning and restructuring, major acquisitions and international expansion that underpinned the company’s trajectory.
Singer holds an MBA with distinction from Harvard Business School and a bachelor’s degree from the University of Virginia.
