Nvidia said it would record a $5.5 billion charge on its quarterly earnings and disclosed that the U.S. will now require a license for exporting the company’s H20 processors to China and other countries.

The government informed the chip maker on Monday that the new requirement would be in place “indefinitely,” the company said in a filing. First-quarter results will include the $5.5 billion charge “associated with H20 products for inventory, purchase commitments and related reserves,” the filing says.

Nvidia shares fell more than 6% in after-hours trading. The company had designed the H20 chips to enable sales of artificial-intelligence processors to China that were allowed under U.S. export controls. The H20 chips have far less processing power than the latest top-of-the-line Nvidia processors.
