Shares of memory chips maker Micron (NYSE:MU) fell 7.6% in the afternoon session after fears of a global energy price shock hit the semiconductor sector following a sell-off in South Korea’s stock market.
The drop in South Korea’s KOSPI index was triggered by fears related to an Iran conflict, which sparked concerns about a major price shock for liquefied natural gas (LNG). South Korea is one of the world’s largest importers of LNG, so a sustained surge in energy prices could directly increase operating costs and squeeze profits for the country’s semiconductor manufacturers. Major chipmakers like Samsung Electronics and SK Hynix, which dominate the global memory chip supply, saw their stocks fall significantly. This negative sentiment spread to U.S. markets, affecting related semiconductor companies.
The shares closed the day at $379.14, down 8.2% from previous close.

Micron’s shares are extremely volatile and have had 44 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.
The previous big move we wrote about was 27 days ago when the stock dropped 8.9% on the news that uncertainty increased over when key companies can resume large-scale sales of high-end artificial-intelligence chips to China.
The U.S. government reportedly extended its review of export license applications for AI hardware, such as Nvidia’s H200 chips, on national security grounds. This delay created uncertainty for chipmakers and reportedly led some Chinese customers to postpone orders until clearer guidance was issued. While there were earlier signals that some shipments could restart, the extended review process stalled progress, weighing on the stock of major exporters who saw China as a significant market. The situation highlighted the ongoing geopolitical tensions impacting the semiconductor industry’s global supply chain.
Micron is up 19.8% since the beginning of the year, but at $377.77 per share, it is still trading 13.7% below its 52-week high of $437.80 from February 2026. Investors who bought $1,000 worth of Micron’s shares 5 years ago would now be looking at an investment worth $4,239.
