Nvidia board opens probe into Jensen Huang affair; shares fall 4% after hours

The board is explicitly separating personal conduct from operational and security risk, and keeping Huang in place — a signal that governance continuity is being prioritized over the disclosure itself. The after-hours move reflects headline shock more than a reassessment of the business, since no trade-secret or national-security exposure was found. The open questions are whether the independent probe surfaces anything that contradicts that framing, and whether the discount persists once regular trading absorbs the news.
