Kathmandu. Jensen Huang, the co-founder and CEO of the American chip maker Nvidia, has resigned from his post.

Allegations of extramarital affairs and foreign espionage have surfaced against him. The company’s board of directors said Huang had resigned.

Colette Kress, Executive Vice President and Chief Financial Officer (CFO), will take over as interim CEO.

Huang, 63, apologized in a message to company employees after news emerged that he had an extramarital affair with his wife, Alice Huang.

The incident also raised questions about the company’s leadership and security.

Born in Taiwan, Jensen Huang co-founded the American technology company Nvidia in 1993. Since then, he has been at the helm of the company consistently.

The New York Times has also claimed that he is having an extramarital affair with the company’s vice president, Kimberly Powell. Earlier, the relationship with Alice Huang, a senior executive of a Singapore-based data center company, was made public.

Nvidia’s shares have fallen after the details of their personal relationships became public. Shareholders have also filed a collective lawsuit against the company and Huang for not providing necessary information about their relationship with investors. Nvidia is one of the most influential technology companies in the world that produces chips for artificial intelligence (AI) technology.
