Jensen Huang has resigned as chief executive of Nvidia, the company’s board announced, Radio Romania reports.

Chief financial officer Colette Kress was named interim chief. Shares plunged more than 13% at the open of U.S. markets shortly after the news.

The departure follows a New York Times report that Huang had a second extramarital relationship with someone in the company’s leadership.

On Sunday he acknowledged an extramarital relationship with a woman who, according to press reports, works at another firm. Media sources wrote that she may have spied for China.

Beijing warned the United States not to use espionage allegations as a pretext to tighten technology export curbs again.

Nvidia is already investigating the relationship Huang admitted, and the FBI is conducting its own inquiry, according to Radio Romania citing the BBC.

Huang steered Nvidia through a surge in AI chip demand; the abrupt resignation rattled investors and the wider tech supply chain.
