Micron Technology reported better-than-expected fiscal Q3 earnings and guided for $50 billion(約8兆円) in Q4 revenue, beating Wall Street's $43 billion(約6.9兆円) forecast. The company also signed multi-year customer agreements covering a meaningful portion of its DRAM and NAND output, providing contracted supply assurance to large cloud providers. This combination directly refutes recent market fears that AI memory demand was peaking and offers the broader semiconductor sector a concrete data point that orders remain strong.

Micron reported fiscal Q3 revenue of about $41.5 billion(約6.6兆円) (up from $23.9 billion(約3.8兆円) in the prior quarter and $9.3 billion(約1.5兆円) a year ago), with a gross margin of 84.6% and adjusted earnings per share of $25.11. The company guided fiscal Q4 revenue to $50 billion(約8兆円), plus or minus $1 billion(約1600億円), and expects gross margin to climb to about 86% with adjusted earnings per share of $31.00, plus or minus $1.00.
Why it matters
Micron announced multi-year Strategic Customer Agreements that lock in volume and provide pricing visibility. These 16 signed agreements represent about 20% of Micron's DRAM volume and a third of its NAND volume over the agreement period—a direct signal that large cloud customers are committed to sustained memory orders rather than pulling back. The cloud memory business unit, Micron's most direct AI-facing segment, grew revenue from $3.39 billion(約5400億円) a year ago to $13.77 billion(約2.2兆円) with an operating margin of 78%, contradicting market fears of AI demand collapse.
What to watch
Capital expenditures climbed to $7.1 billion(約1.1兆円) in fiscal Q3 as Micron races to bring new HBM (high-bandwidth memory) capacity online. The memory business remains cyclical, with a history of customer over-ordering during supply shortages and cancellations afterward; the Strategic Customer Agreements have not disclosed their exact terms, creating uncertainty about how durable these commitments truly are.
