Micron’s Record Margins Mask a Deepening Memory Crunch
Micron Technology reported record fiscal Q4 2026 revenue of $54.2 billion and 87% gross margins, driven by an AI-fueled memory shortage. CEO Sanjay Mehrotra confirmed that 75% of 2027 supply is already sold, with prices significantly higher than 2026 levels. The company expects supply-demand imbalances to persist through 2028, as manufacturing capacity is prioritized for high-bandwidth memory (HBM) used in AI servers, limiting availability for consumer devices. While Micron has secured 26 long-term agreements, investors remain cautious about potential margin peaks, causing the stock to lag despite strong earnings.
Key points
- Micron’s fiscal Q4 2026 revenue reached $54.2 billion, up 379% year-over-year, with adjusted EPS of $33.42.
- Gross margins hit 87% in Q4, though guidance for Q1 2027 shows a slight dip to 86.25% due to temporary compensation effects.
- 75% of Micron’s 2027 memory output is already committed, with most current sales discussions focused on 2028.
- Samsung’s Kim Taewoo noted HBM will consume nearly 30% of DRAM wafer capacity in 2027, up from 20% in 2026.
- Micron has 26 long-term supply agreements, up from 16 last quarter, with some extending to 2031.
- The company exited the consumer RAM market in December 2025 to focus on strategic AI and server customers.
Background
Micron’s stock has surged over 550% in the past year, driven by AI infrastructure demand. Previous coverage highlighted a $50 billion expansion in Boise and debates over whether the memory cycle is a durable structural shift or a classic boom-bust commodity. Recent analyst price targets have ranged from $1,550 to $1,625, reflecting confidence in sustained AI spending despite valuation concerns.
How outlets are covering it
Barron’s emphasizes the 'bless and curse' nature of Micron’s 87% margins, noting that any hint of a peak triggers investor exits, despite strong long-term agreements. Ars Technica focuses on the consumer impact, highlighting that manufacturing capacity is prioritized for AI HBM, leaving consumer devices with limited supply and higher prices. Yardeni QuickTakes frames the results as proof that the AI buildout has 'plenty of runway,' citing Goldman Sachs’ raised 2027 hyperscaler capex forecast to $1.2 trillion.

Why it matters
The memory shortage is reshaping the tech supply chain, forcing a reallocation of resources from consumer electronics to AI infrastructure. This structural shift could sustain high margins for memory makers but may lead to higher prices and lower configurations for consumer PCs, smartphones, and gaming consoles. The durability of long-term agreements suggests the shortage is not a temporary blip, potentially re-rating memory stocks from cyclical commodities to growth assets.
What to watch
Investors will watch Micron’s Q1 2027 earnings for signs of margin recovery and further updates on capital allocation. The lifting of CHIPS Act restrictions in December may provide clarity on future expansion. The market will also monitor whether hyperscaler capex continues to rise, as Goldman Sachs forecasts $1.2 trillion in 2027, and if consumer device prices continue to climb due to constrained memory supply.
