Micron Has Sold Its Entire HBM Output Through 2026 — Yet the Stock Is Stuck in a Correction
Published on 07/09/2026 at 10:07 | Redaktion boerse-global.de
Micron’s high-bandwidth memory capacity is booked solid until the end of 2026, with some customer contracts stretching into 2027 and beyond. The company can only fill 50 to 60 percent of current demand for these indispensable AI accelerator chips. Yet the stock closed on Wednesday at €831.00, a full 24.7 percent below its June 25 record of €1,103.80. That disconnect between operational heat and market chill defines the central question facing investors: Is this a temporary valuation stress test inside a multiyear super-cycle, or the first signal that the memory sector is reverting to its boom-bust DNA?
The bull case rests on numbers that are hard to ignore. Micron has locked in roughly $100 billion in guaranteed minimum revenue through long-term customer agreements, de-risking the massive capital expenditure program underway. New fabs are rising in Japan, Taiwan, Boise and Syracuse — many with government subsidies — and the company expects to capture 20 to 25 percent of the HBM market by late 2026. Its HBM4 generation is already in volume production, and a recent spate of automotive contracts with Ford and General Motors shows the company is diversifying beyond hyperscalers. For the fourth fiscal quarter, management guided revenue of around €50 billion, well above analyst estimates, following a record quarter. Some industry observers have coined the term “Memflation” to describe the effect of AI-driven memory demand on overall semiconductor revenue, which they expect to exceed €1.3 trillion by the end of 2026.
The bearish counter-argument is just as data-rich. The memory industry has never escaped its cyclical nature: capacity gluts have always followed capacity crunches. While HBM glows, the broader DRAM and NAND markets are already showing signs of softening, pulled down by weak PC and smartphone demand. Meanwhile, global wafer capacity is expanding, and Chinese manufacturers are gaining credibility in standard memory products, which could compress pricing in future downturns. On the competitive front, SK Hynix is planning a Nasdaq listing that could draw capital and intensify price pressure. Macro headwinds are also stacking up — ten-year U.S. Treasury yields remain above 4.5 percent, and Sino-American trade tensions show no sign of easing. Micron’s own capital spending is set to hit roughly €10 billion in Q4, a figure that carries all the execution risks of construction delays, yield ramp issues and the possibility that the AI demand forecast overpromises. A customer base concentrated among a handful of key hyperscalers adds to the vulnerability: any shift in their build-out plans would hit Micron disproportionately.
Should investors sell immediately? Or is it worth buying Micron?
Technically, the stock is walking a fine line. The 50-day moving average sits at €786.53, giving the current close a cushion of just 5.65 percent. The 14-day relative strength index at 46.6 is neutral, neither oversold nor overbought. The 30-day annualized volatility of 111.34 percent underscores that this is a name prone to sharp swings in both directions. A break below the €775 support zone would puncture the current bull thesis and suggest a deeper valuation reset; holding above the 50-day line points to a consolidation that could resolve higher once the next catalyst emerges.
The next catalysts are likely to come from two places. The first is any management comment on HBM allocation for 2027 — so far only full utilisation through 2026 has been confirmed. The second is the trajectory of standard DRAM pricing in the second half of 2026. If HBM demand continues to outstrip supply and the DRAM market does not tip into oversupply, the current pullback will look like a pause within a structural shift. If pricing for mainstream memory rolls over, history suggests the entire sector — including the HBM premium — can sour quickly. The Tongluo fab is not slated to start production until fiscal 2028, and Hiroshima’s tool installation comes in the second half of that year. Until then, the memory cycle’s oldest rule still applies: the cure for high prices is high prices, and nothing stays tight forever.
