Micron Reports Blowout Quarter, Warns Memory Shortage

Micron Technology reported record Q3 fiscal 2026 results, with revenue of $41.46 billion, up 346% year over year from $9.3 billion and 74% sequentially, according to CNBC and Tom's Hardware. Adjusted EPS of $25.11 beat the LSEG consensus of $20.78. Gross margin reached a company-record 84.9%, up 5 percentage points sequentially, driven by pricing strength and a favorable product mix. Management guided Q4 revenue to $50 billion +/- $1 billion with gross margin of approximately 86%, materially above the Street estimate of roughly $43 billion, per CNBC.

Micron disclosed 16 Strategic Customer Agreements (SCAs) with hyperscalers, cloud providers, automakers, and AI infrastructure companies. Fourteen of the 16 agreements carry minimum contracted revenue of approximately $100 billion through calendar 2030, per Tom's Hardware and investing.com. Customers paid $22 billion in upfront deposits - roughly $18 billion in cash and $4 billion in letters of credit - to secure future supply, per earnings disclosures. Micron's entire HBM supply for calendar 2026 is sold out under multi-year agreements, according to the earnings call.

CEO Sanjay Mehrotra said on the earnings call that DRAM and NAND demand "significantly" exceeds supply and will remain tight "beyond calendar 2027." Mehrotra attributed supply constraints to long fab lead times, skilled worker shortages, regulatory complexity, and energy infrastructure requirements, per CNBC. Q4 guidance implies further margin expansion as HBM and high-density DRAM mix continues to shift.

The supply structure Micron describes is relevant for practitioners planning AI infrastructure: memory fab buildouts require multi-year greenfield construction and specialized workforce development, which means demand spikes cannot be absorbed quickly. The shift to multi-year supply agreements with upfront deposits is a structural change from historical quarterly negotiation cycles, reducing spot-market availability and concentrating pricing power among incumbents. For data center architects and procurement teams, this makes early contracting and memory roadmap alignment more critical than in prior cycles.

Monitor fab capacity announcements and greenfield progress from Micron and peers (Samsung, SK Hynix), HBM pricing trends in the spot market, and quarterly disclosure of SCA utilization rates. Customer deposit flows in future quarters will indicate whether the demand pipeline is extending further.
