SK Hynix's board approved roughly $38 billion for two new memory fabs in South Korea, and the stock fell 5% as investors weighed the scale of the spending against a delayed shareholder-return update. Seagate, Micron, and SanDisk shares also fell the same day, though Seagate's 7% drop reflects profit-taking after a 210% year-to-date rally rather than any new company-specific news.
SK Hynix stock fell 5% to $136.79 midday Friday after the company's board approved roughly $38 billion to build two new memory fabs in South Korea. The muted reaction ties back to the sheer scale of the capital spending, plus a decision to defer the next shareholder-return update to the third quarter.
SK Hynix Commits $38 Billion to New Fabs
The board green-lit 54 trillion won for two new fabs: a DRAM plant known as Yongin Y2 at roughly 35.2 trillion won, and a NAND flash plant known as Cheongju M17 at roughly 19.1 trillion won. About two-thirds of the outlay targets DRAM, aligning capacity with AI-driven memory demand.
Management also pulled forward the broader Yongin cluster timeline, now aiming to finish all four planned Yongin fabs by 2033 rather than 2045. SK Hynix's CEO has warned that 2027 could bring the most severe memory shortage the industry has seen, framing the demand as a structural shift rather than a cyclical bounce.
The stock listed on NASDAQ on July 10, and its Seoul-listed shares closed down 5% ahead of the U.S. session. The company also posted record Q2 2026 operating profit, up 557% year over year, though the report still missed analyst estimates on revenue.
Seagate Leads the Sector Lower
Seagate Technology stock fell 7% to $797.09 despite no clear company-specific catalyst. Shares were up 210% year to date heading into Friday, so the drop looks like profit-taking after a vertical run rather than a reaction to new news.
Seagate's late-July print, however, delivered a beat on revenue and non-GAAP EPS, with guidance for Q1 FY2027 revenue of $4.1 billion plus or minus $100 million. Nothing in that setup changed Friday, which supports the read that traders are simply trimming exposure after a big move higher.
Micron and SanDisk Hold Up Better
Micron Technology stock slipped only 2% to $866.80, a notable divergence given the sector's news flow. Its multi-year Strategic Customer Agreements and dominant HBM4 position appear to be insulating Micron from the capex-driven anxiety hitting SK Hynix.
SanDisk shares dropped 3% to $1,225.15 after the company reported Q4 FY2026 results on August 5 showing revenue up 371.6% year over year. As a result, SanDisk shares remain up 419% year to date even after the pullback.
The Roundhill Memory ETF fell 2% to $50.37, a fund that concentrates 24.99% of its holdings in Samsung Electronics, 24.22% in SK Hynix, and 23.83% in Micron. Investors can watch for analyst reactions to the fab plan and Micron's next earnings report, scheduled for September 28, for signs of whether Friday's selling was isolated profit-taking or the start of broader sector pressure.
