Micron has already contracted most of its 2027 HBM supply
US memory maker Micron reported fiscal fourth-quarter revenue of $54.23 billion on 30 September. The company said it had signed agreements for most of its 2027 HBM bit supply and could not yet see supply and demand coming into balance.
According to Micron's results, released at 23:01 TRT (UTC+3) on 30 September, revenue in the quarter ended 3 September was $54.23 billion, with an adjusted gross margin of 87.0%. Fiscal 2026 revenue reached $133.19 billion, and net capital expenditure $27.37 billion. The company forecasts revenue of $61.5 billion (±$1.5 billion) for October–December. HBM, the high-bandwidth memory stacked alongside AI accelerators, sits at the centre of this demand.
According to the presentation reported by Investing.com, quarterly revenue rose 379% from a year earlier, and DRAM made up 73% of revenue at $39.8 billion. HBM revenue grew faster than total revenue, and most of the 2027 HBM bit supply has been contracted at markedly higher prices. Micron said 26 strategic customer agreements cover more than 35% of revenue through 2030 and that it had received $32 billion in commitments from customers. Management said DRAM would remain the main constraint for data centres until 2028.
The capacity schedule is weighted towards Asia. According to the presentation, the HBM plant in Singapore will start production in early 2027, the Taiwan plant in mid-2027 and the DRAM expansion in Japan in late 2028. According to Seeking Alpha, the results came in well above expectations, yet the shares rose only 0.4% in after-hours trading. Investing.com commented that the market had already priced in a strong result.
Talay assessment
Bottom line
Micron's results confirm that the AI-driven memory shortage has carried into 2027 and that pricing power remains with producers. Multi-year contracts and cash commitments are moving the cyclical memory market towards a more contract-based structure. Because much of the new capacity will open in Singapore, Taiwan and Japan, memory supply remains exposed to geopolitical risk in Asia.
Likely effects
- Cost of AI infrastructureNegative1–6 months
With most 2027 HBM supply already sold at higher prices, accelerator and server costs look set to stay high.
- Korean and Taiwanese memory chainPositive1–6 months
Micron's statement that it cannot see supply and demand balancing reinforces the industry view that Samsung and SK Hynix face the same shortage.
- Consumer electronicsNegative6 months+
If DRAM remains the main data centre constraint until 2028, memory cost pressure will persist for phone and computer makers.

New capacity does not come online before mid-2027, and memory prices stay high.
