Micron Technology beat fourth-quarter revenue estimates by $3.78 billion and raised first-quarter guidance, citing unprecedented demand from AI datacenter buildout. The company posted $54.23 billion in Q4 revenue against a $50.45 billion consensus estimate, a 7.49 percent beat. For Q1, Micron issued guidance with a midpoint of $61.5 billion, 6.8 percent above the $56.77 billion Wall Street consensus.
Micron supplies dynamic random-access memory and NAND flash to hyperscalers building out clusters for large language models and related workloads. The company's guidance implies continued demand for memory and storage chips that power AI training and inference infrastructure.
Micron, the third-largest DRAM manufacturer globally, operates fabs in the United States, Japan and Singapore. Its memory chip production capacity has been a constraint for AI infrastructure deployment. The company has announced expansion plans, including a new fab in Indiana that received Department of Commerce funding under the CHIPS and Science Act.
After-hours trading moved Micron shares up 0.4 percent following the announcement. Broader semiconductor indices have tracked AI demand cycles closely. Other major memory suppliers including SK Hynix and Samsung have reported strong datacenter bookings in the same period.
Micron's Q1 guidance of $61.5 billion represents a 13.5 percent quarter-on-quarter increase from the Q4 beat itself. That sequential acceleration is unusual outside of seasonal patterns and points to customer pull-through rather than channel building.
The document to watch is Micron's next earnings call transcript in December, where management must detail whether Q1 bookings have extended visibility into Q2 2027 or whether the guidance rests on near-term orders only.
