Nvidia’s board is meeting to decide whether to oust CEO Jensen Huang, a source familiar with the matter told the Reuters news agency, as the world’s dominant supplier of AI processors grapples with reports of two extramarital affairs involving its longtime ⁠leader.

The reports mark a sharp escalation in a controversy that began with revelations about Huang’s relationship with Alice Huang, a woman US intelligence has said was involved in facilitating shipments of Nvidia chips to Chinese firms.

In a memo to employees on Sunday, Huang acknowledged being unfaithful to his wife and took “full responsibility,” but gave no details about the relationship.
