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 more than 6% 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 disclosure is the strongest sign so far that Nvidia’s historic growth could be slowed by increased export restrictions on its chips, which the U.S. government says can be used to create supercomputers for military uses. Nvidia reports fiscal first-quarter results on May 28.

During President Biden’s administration, the U.S. restricted AI chip exports in 2022 and then updated the rules the following year to prevent the sale of more advanced AI processors. The H20 is an AI chip for China that was designed to comply with U.S. export restrictions. It generated an estimated $12 billion to $15 billion in revenue in 2024.

Nvidia 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. Huang warned that competition in China is growing, and for the second straight year, Nvidia listed Huawei as a competitor in its annual filing.

China is Nvidia’s fourth-largest region by sales, after the U.S., Singapore, and Taiwan, according to the company’s annual report. More than half of its sales went to U.S. companies in its fiscal year that ended in January.

Nvidia’s H20 chip is comparable to the H100 and H200 AI chips used in the U.S. and other countries, but it has slower interconnection speeds and bandwidth. It’s based on a previous generation of AI architecture called Hopper introduced in 2022. Nvidia is now focusing on selling its current generation of AI chips, called Blackwell.

DeepSeek, the Chinese company whose competitive AI model R1 unveiled earlier this year upended markets, used H20 chips in its research.

In addition to the existing Chinese export controls, Nvidia also faces new restrictions on what it can export starting next month, under “AI diffusion rules” first proposed by the Biden administration.

Nvidia has argued that further controls on its chips would stifle competition and potentially even erode U.S. competitiveness in technology. The company previously said it moved some of its operations, including testing and distribution, out of China after the 2022 export controls.

At the company’s annual conference last month, when asked about Chinese export controls, Huang said Nvidia works to comply with the law, but he also noted that about half of the world’s AI researchers are from China, and many of those work at U.S.-based AI labs. 

Nvidia said in Tuesday’s filing that the U.S. government told the company on Monday that the license requirement for H20 chips would be in effect “for the indefinite future.”

Nvidia shares have dropped 16% this year, largely due to President Trump’s announcement of widespread tariffs on top trading partners. While exemptions have been made on various electronics products, including smartphones, computers and semiconductors, Trump and some officials said over the weekend that the reprieve was temporary and part of plans to apply separate tariffs to the sector.

Shares of Advanced Micro Devices dropped more than 7% in after-hours trading on Tuesday following Nvidia’s disclosure. AI chipmaker Broadcom fell almost 4%.

Design software maker Figma said on Tuesday that it has submitted paperwork to the U.S. Securities and Exchange Commission for an initial public offering.

The confidential filing lands 16 months after the company scrapped a deal to be acquired by Adobe for $20 billion due to regulatory pressure in the U.K. The San Francisco startup had originally agreed to the deal 2022. Adobe paid Figma a $1 billion termination fee.

Figma’s software is popular among designers inside companies who need to collaborate on prototypes for websites and apps. The company was valued at $12.5 billion in a 2024 tender offer.

“There are two paths that venture-funded startups go down,” Dylan Field, Figma’s co-founder and CEO, said in an interview with The Verge last year. “You either get acquired or you go public. And we explored thoroughly the acquisition route.”

The announcement lands at a precarious moment for the tech IPO market, which has been largely dormant since late 2021. The Trump presidency was expected to revive new offerings due to promises of less burdensome regulations.

But after filing their prospectuses with the SEC, fintech company Klarna and online ticket marketplace StubHub delayed their IPOs earlier this month following the market turmoil caused by Trump’s announcements on widespread tariffs. Digital banking service Chime, which had filed confidentially with the SEC, also postponed its planned offering.

Turo, a car-sharing service, withdrew its IPO prospectus in February, three years after filing its initial prospectus.

Figma was founded in 2012 and is backed by investors including Andreessen Horowitz, Durable Capital, Greylock Partners, Index Ventures, Kleiner Perkins and Sequoia Capital. The company, which ranked 26th on CNBC’s Disruptor 50 list in 2024, had about $600 million in annual revenue as of early last year.

Meta CEO Mark Zuckerberg considered spinning out Instagram in 2018 on concerns about the rising threat of antitrust litigation against Facebook, according to an email presented Tuesday in a Washington, D.C. courtroom.

During Zuckerberg’s second day of testimony in Meta’s antitrust trial with the Federal Trade Commission, lawyers representing the FTC introduced an email from May 2018, in which Zuckerberg appeared to comment on the possibility of separating the photo-sharing app his company purchased in 2012 for $1 billion.

“And i’m beginning to wonder whether spinning Instagram out is the the only structure that will accomplish a number of important goals,” Zuckerberg wrote in the email. “As calls to break up the big tech companies grow, there is a non-trivial chance that we will be forced to spin out Instagram and perhaps WhatsApp in the next 5-10 years anyway. This is one more factor we should consider.”

Facebook bought Instagram in 2012, when the photo app had 13 employees and Zuckerberg was poised to take his company public in what, at the time, was the largest tech IPO on record. The purchase of Instagram and 2014 acquisition of WhatsApp for $19 billion are at the heart of the blockbuster antitrust trial that kicked off Monday and could last weeks.

The FTC alleges that Meta monopolizes the social networking market, and has argued that the company shouldn’t have been able to complete those acquisitions. The agency is seeking to cleave the apps from Meta as a possible remedy.

Meta disputes the FTC’s allegations and claims the regulator mischaracterizes the competitive landscape and fails to acknowledge a number of rivals like TikTok and Apple’s iMessage, and not merely other apps like Snapchat. Earlier in the trial, the FTC also presented an Oct. 2013 email in which Zuckerberg told other Facebook executives that Snap CEO Evan Spiegel rebuffed his $6 billion offer to buy Snapchat.

Zuckerberg also said in the 2018 email that the company’s “best estimates are that, had Instagram remained independent, it would likely be around the size of Twitter or Snapchat with 300-400 million MAP today, rather than closer to 1 billion.” MAP is short for monthly active people.
