Micron earnings moved the AI memory market into sharper focus after the chipmaker reported $54.23 billion in fiscal fourth-quarter revenue and issued a $61.5 billion midpoint forecast for the current quarter. The results show how data-center demand, high-bandwidth memory and higher-capacity server products are reshaping Micron Technology’s business mix.
Key Takeaways
- Micron reported $54.23 billion in fiscal Q4 2026 revenue, up from $41.46 billion in the previous quarter and $11.32 billion a year earlier
- Core Data Center revenue reached $18.00 billion, making it Micron’s largest business unit by quarterly sales
- Micron expects fiscal Q1 2027 revenue of $61.5 billion, plus or minus $1.5 billion
- The company is shipping HBM4 in volume and sampling a 512GB DDR5 RDIMM for next-generation servers
Micron Earnings Put Data Centers at the Center of Growth
Micron Technology reported fiscal fourth-quarter results on Sept. 30 for the period ended Sept. 3. Revenue climbed to $54.23 billion, while GAAP net income reached $37.70 billion, or $32.87 per diluted share. Adjusted earnings were $33.42 per share.
Revenue exceeded the roughly $51.33 billion analyst estimate cited by IBD and The Wall Street Journal. Adjusted earnings also topped the $31.72 consensus cited by both publications.
The bigger shift was inside Micron’s business mix. Core Data Center Business Unit revenue rose to $18.00 billion from $11.52 billion in the previous quarter and $1.58 billion a year earlier. Cloud Memory revenue reached $16.28 billion.
Core Data Center gross margin reached 90%, up from 87% in the third quarter. The figures put server memory and storage at the center of Micron’s current expansion as major technology companies increase AI infrastructure spending across data centers.
For fiscal 2026, Micron reported $133.19 billion in revenue, compared with $37.38 billion in fiscal 2025. Operating cash flow reached $89.68 billion.
AI Memory Demand Is Reshaping the Product Mix
High-bandwidth memory has become central to AI hardware because accelerators require large amounts of data to move rapidly between memory and processors. Micron said HBM4 was already in high-volume shipments for a lead customer platform, with qualification samples delivered to additional customers.
Chief Executive Sanjay Mehrotra said in the fourth-quarter release, “Micron delivered record fiscal 2026 results, and we expect an even stronger fiscal 2027.” The second part of that statement remains company guidance rather than a guaranteed outcome.
Micron has also said HBM production uses significant wafer capacity and can pressure supplies of conventional DRAM. That matters as AI chip demand grows alongside requirements for server memory and storage across data-center systems.
The shift extends beyond HBM. Micron said revenue from its server LPDDR SOCAMM portfolio more than doubled sequentially in fiscal Q4. It also completed multiple customer qualifications for 1-gamma server RDIMMs running at 8,800 MT/s.
Micron’s $61.5 Billion Forecast Extends the Revenue Run
Micron expects fiscal first-quarter 2027 revenue of $61.5 billion, plus or minus $1.5 billion. It projected adjusted gross margin of about 86.25% and adjusted diluted earnings of $38.15 per share, plus or minus $1.00.
The revenue midpoint is above the roughly $57.4 billion analyst consensus cited by MarketWatch and IBD. Management’s forecast indicates that the demand conditions supporting fiscal Q4 are expected to continue into the current reporting period.
Memory remains a cyclical industry, however. Pricing, customer inventories, manufacturing capacity and product transitions can change quickly. Micron’s disclosures identify customer demand, manufacturing execution and broader operating conditions among factors that could cause actual results to differ from guidance.
Micron recorded $10.77 billion in net capital expenditures in the fourth quarter and $27.37 billion for the full year, reflecting the manufacturing requirements behind its current product cycle.
Server Memory and Storage Broaden the AI Cycle
Micron’s product activity shows that the AI memory cycle extends into conventional server memory and storage. In September, the company announced a 512GB DDR5 RDIMM capable of speeds up to 9,200 MT/s. AMD and Intel are validating the module, with Micron targeting volume production in the second half of 2027.
The company also said its 7600 PCIe Gen 5 and 9650 PCIe Gen 6 solid-state drives are shipping to customers for KV-cache applications. KV-cache storage retains information generated during AI inference so systems can reuse previously processed context.
Micron reported a volume ramp for its 6600 ION SSD and said it secured design wins with every Tier 1 original-equipment manufacturer customer for AI workstation products. Those are company-reported milestones and do not indicate uniform deployment volumes.
The latest Micron earnings therefore place data-center memory, HBM, server DRAM and storage at the center of the company’s current financial performance. Fiscal Q1 2027 results will provide the next measurement of how closely revenue and margins track current guidance.
