Megaspeed has become one of Nvidia’s biggest customers in Southeast Asia

Singapore-based Megaspeed purchased more than $4.8 billion worth of Nvidia chips over the past two years, according to The New York Times. Megaspeed has become one of Nvidia’s biggest customers in Southeast Asia.

Alice Huang, a Chinese citizen and chip buyer, is a top executive at Megaspeed. She was previously a television reporter in China before becoming a top executive at the Singapore-based company.

The New York Times reported last month that U.S. intelligence agencies had discovered that Jensen Huang had developed a close relationship with Alice Huang and determined that she was feeding information directly to Beijing. The two are not related, according to The New York Times.

Nvidia’s board of directors said Sunday it was opening an investigation into reports that CEO Jensen Huang was the “target of a foreign intelligence effort.”

In a statement, the board said it had “no reason to believe that either national security or Nvidia secrets were compromised,” but that the inquiry would examine all available information.

The announcement came after Jensen Huang acknowledged to the board that he had been intimate with a business executive whom U.S. intelligence determined was gathering information for Beijing, The New York Times reported.

The board said Jensen Huang “fully supports the review and has committed to cooperating with it.” Jensen Huang, 63, will remain CEO during the investigation.

Jensen Huang apologized in a message to the company, according to The New York Times. “I was unfaithful to my wife,” he said. “My actions hurt her and our children. There is no excuse for what I did. I am deeply sorry.”
