Singapore has barred Alice Huang from re-entering the country after an investigation into possible offences linked to server exports, the Ministry of Home Affairs said on Thursday.

Huang, a former executive at Megaspeed, a customer of the chipmaker Nvidia, was investigated over the purchase of servers that were exported through Singapore to Malaysia without entering the Singapore market, the ministry said. She was investigated in her role as the firm's then chief executive, chairperson and one of its key controllers.

No espionage investigation, ministry says

The ministry said the investigation did not concern espionage and that there was insufficient evidence to establish that Huang had committed any offences. It said, however, that she gave police information she knew to be inaccurate and played down her role at Megaspeed, a cloud computing company.

She was issued with a stern warning, had her passport returned on 26 February 2026 and left Singapore the same day, barred from returning. Investigations into Megaspeed and six other people are continuing, the ministry said.

The Nvidia scandal

The case sits at the centre of the scandal that has shaken Nvidia. The chipmaker said on Thursday that its co-founder and chief executive, Jensen Huang, 63, was stepping down, after reports of two extramarital affairs, including one with Alice Huang, whom US officials suspect of spying for Beijing.

Bloomberg has reported that Alice Huang is now living in Beijing with the knowledge of security officials. Taiwan's interior minister told lawmakers on 11 November that her entry permit had been revoked. Singapore police said in October 2025 that they were investigating Megaspeed over suspected breaches of domestic law.

Huang has not been charged with any offence. The ministry said its investigation was not based on a request from another country.
