Micron announces $9.3 billion investment in high-bandwidth memory (HBM) production capacity in Japan.
Micron Technology broke ground on a new chip fabrication facility in Higashi-Hiroshima on July 4, 2026, with Japan pledging up to $3.3 billion in subsidies for the $9.3 billion project. The facility will produce High-Bandwidth Memory (HBM) chips, the critical component powering AI processors, with first deliveries expected by summer 2028. Yet even as Micron expands its global footprint to capitalize on surging demand, shareholders have endured one of the stock's worst weeks in recent memory.
Micron shares closed at 815.50 euros (approximately $873) on Tuesday, marking a 5.39% single-day loss that deepened the weekly rout to 19.56%. The pullback leaves the stock 26.12% below its all-time high of 1,103.80 euros reached on June 25—a dizzying reversal for a company that just posted a record quarter. The sell-off appears driven less by operational deterioration than by a confluence of technical and sentiment-related headwinds.
Late June brought a class-action lawsuit against Micron, Samsung, and SK Hynix, alleging coordinated price-fixing through artificial production cuts on certain memory chips. Around the same time, regulatory filings revealed that CEO Sanjay Mehrotra had sold over $45 million worth of Micron stock. These disclosures, combined with a sector-wide rotation away from AI winners, proved sufficient for traders to lock in profits after an extraordinary rally. The stock still trades 696.85% higher over the past twelve months and has gained 203.16% year-to-date.
The volatility contradicts deteriorating fundamentals. Just a week earlier, Micron had surged following its fiscal third-quarter report, which showed revenue of $41.46 billion and adjusted net income of $28.86 billion, with gross margin around 84.9%. The company guided fourth-quarter revenue to approximately $50 billion and gross margin toward 86%. Management also secured forward contracts worth over $100 billion, with CEO Mehrotra stating there is "no line of sight" to supply catching demand before 2028. HBM4 chips are already shipping in volume to key customers, and HBM4E is in development for mass production in 2027.
The Japan investment represents one element of an aggressive global capacity expansion. Micron is constructing two advanced fabrication plants in Idaho and planning up to four additional facilities in New York, aiming to return 40% of its DRAM output to the United States. A new wafer fab in Singapore opened in January 2026, and the company acquired Powerchip's Tongluo-P5 facility in Taiwan in March. These initiatives are designed to prevent the supply bottlenecks that have historically plagued the memory market and to reinforce Micron's position as an HBM leader, even as competitor SK Hynix dominates the segment with an estimated 60% market share.
SK Hynix is preparing to list American Depositary Receipts on the Nasdaq as early as July 10, a move that could divert capital flows from Micron. Concurrent capacity expansions by Samsung and SK Hynix also threaten to moderate pricing once supply normalizes, though analysts expect the current demand surge to persist for several more quarters.
From a technical perspective, Micron shares sit 4.77% above their 50-day moving average of 778.39 euros but 104.67% above the 200-day average of 398.45 euros—a reflection of how steep the rally had become. The relative strength index stands at approximately 45.5, hovering in neutral territory after weeks of extreme readings. Annualized 30-day volatility stands at 111.7%, underscoring that turbulence is likely to continue.
Despite the weekly decline, the long-term investment thesis remains intact. The 52-week low of 90.64 euros, set in August 2025, now appears distant. The stock trades nearly eight times that level even after the recent correction. Analysts' consensus price target of 1,302 euros implies roughly 60% upside from current prices. The sell-off appears more a recalibration of how much of Micron's AI boom was already priced in than a verdict on the company's execution capability. With a $100 billion order book and a new Japanese factory breaking ground, the fundamental narrative remains compelling.
