Asian technology stocks slumped after a report that Nvidia Corp.’s next-generation AI server rack system has been delayed by more than a year due to manufacturing difficulties.

Research firm SemiAnalysis said in an X post that Nvidia’s Kyber NVL144 hit setbacks in the construction of printed circuit boards for the platform. 

“Our road map is intact,” an Nvidia spokesperson said in an emailed statement.

The report landed as AI stock investors are growing increasingly anxious, with even the smallest setback sparking outsized reactions after a yearslong rally. Last week, global tech stocks whipsawed on headlines hinting at potential overcapacity in the AI buildup and growing competition.

Japan’s Ibiden Co., a PCB maker that counts Nvidia as its largest client, dropped as much as 10%. Among related suppliers, Kingboard Laminates Holdings Ltd. tumbled 18% in Hong Kong, Elite Material Co. fell 10% in Taiwan and Samsung Electro-Mechanics Co. slid 11% in South Korea.

The SemiAnalysis report spurred “weakness across regional tech” Monday, said Shawn Oh, head of Korea cash equities at NH Investment & Securities Co. in Seoul. The prospect of a Kyber NVL144 delay together with other points in the post are “raising uncertainty around Nvidia’s next-generation scale-out road map and creating a wider competitive window for alternative AI platforms,” he added.

The stock declines showed investors are wary of any potential negative developments after big run-ups in AI-related stocks. Samsung Electro-Mechanics has surged more than 600% this year, while Kingboard Laminates is up more than 470%.

An MSCI Inc. gauge of sector shares is down 8.5% in the past two weeks, extending its loss Monday with PCB makers among the leading decliners.

A delay to Kyber does not necessarily imply weaker AI capex, but “it more likely suggests that Nvidia’s most ambitious next-gen system architecture may take longer to deploy, which is not entirely surprising,” said Gary Tan, a portfolio manager at Allspring Global Investments.

“Today’s weakness is driven more by profit-taking, sector rotation and caution ahead of the US reopening after the July 4 holiday,” Tan said. He also cited a possible drag from this week’s mega US listing for Korean memory maker SK Hynix Inc. 

An earnings report due Tuesday from Samsung Electronics Co. is the next key point to watch for Asian tech stocks.
