Nvidia said on Tuesday that it will take a quarterly charge of about $5.5 billion tied to exporting H20 graphics processing units to China and other destinations. The stock slid about 4% in extended trading.

On April 9, the U.S. government told Nvidia it would require a license to export the chips to China and a handful of other countries, the company said in a filing.

The filing from Nvidia is the strongest sign so far that Nvidia’s overall growth could be slowed by increasing export restrictions on its chips, which the U.S. government says can be used to create supercomputers for military uses.

The H20 is an artificial intelligence chip for China that was designed to comply with U.S. export restrictions. They generated an estimated $12 billion to $15 billion in 2024.

CEO Jensen Huang said on the company’s last quarterly earnings call in February that revenue from China had dropped to half of pre-export control levels. That amounted to about $17 billion.

Huang warned that competition in China is growing, and for the second straight year, Nvidia listed Huawei as a competitor in its 10K filing with the Securities and Exchange Commission.

Nvidia’s H20 chip is comparable to the H100 and H200 AI chips used in the United States and other countries, but it has slower interconnection speeds.

DeepSeek, the Chinese company that unveiled a competitive AI model earlier this year that upended markets, used H20 chips in its research.

Nvidia reports fiscal first-quarter results on May 28.
