According to Bloomberg, Nvidia disclosed in regulatory filings that the U.S. government has informed the company that the H20 chips, designed to address previous export restrictions, will require a license for future exports to certain countries, and this requirement is "indefinitely" effective.
As a result, Nvidia expects to record approximately $5.5 billion in related losses this fiscal quarter, involving inventory, purchase commitments, and related reserves. Following the news, Nvidia's stock price fell by about 5% in after-hours trading.
