Micron Technology, Inc.
The most accessible pure-play on the AI-driven memory upcycle and an HBM bellwether — the defining question is whether record pricing is a structural, AI-led shift or a classic cyclical peak.
Business Overview
One of the three major memory makers (DRAM + NAND), Micron is increasingly driven by AI data centers and HBM. FQ3-26 revenue was a record $41.5B (~85% gross margin); data-center units are now ~60% of sales. It exited consumer (Crucial) to prioritize enterprise and AI supply.
Revenue Model
Micron sells memory chips (~76% DRAM, 24% NAND). Pricing once swung with supply-demand cycles, but it has shifted much of its volume onto multi-year take-or-pay Strategic Customer Agreements (SCAs) with floor prices — 16 signed, with about half of revenue expected under them. Data-center is now the top demand driver.

Competitive Moat
Memory is a three-player oligopoly (Micron, Samsung, SK Hynix) with steep capital and technology barriers. Micron's edge is HBM — roughly #3 and gaining, qualified on NVIDIA's latest platforms — plus leading-edge nodes and the most aggressive capacity investment among peers.
Competitive Landscape
SK Hynix
The HBM market leader and Micron's main benchmark in high-bandwidth memory for AI accelerators.
Samsung
The largest memory maker overall; Micron is closing the gap in HBM on some 2026 share data.
NVIDIA (key customer)
The anchor AI-accelerator customer; Micron is qualified for its latest HBM4 platforms, tying demand to the AI build-out.
Growth Drivers
AI / HBM demand
AI accelerators need several times the memory of prior systems, and HBM's heavy wafer appetite tightens all memory supply.
16 SCAs
Locked-in SCA pricing
Multi-year take-or-pay agreements set floor prices above prior-cycle peaks, giving unusual visibility into a volatile business.
~$27B capex
Capacity & node leadership
FY2026 capex funds HBM4, leading-edge DRAM/NAND nodes, and new fabs, extending the technology lead.
Risk Factors
Cyclicality
Memory has always been boom-and-bust; record pricing can reverse sharply if AI demand cools or supply catches up.
2028 supply wave
New industry capacity arriving around 2028 is the main threat to the structural-tightness thesis.
Customer concentration
Heavy reliance on a few large AI customers concentrates demand risk.
Key Developments
June 2026
Record FQ3-26: revenue $41.5B (+346% YoY), ~85% gross margin, non-GAAP EPS $25.1; 16 take-or-pay SCAs signed; FQ4 guided to ~$50B.
February 2026
Wound down the Crucial consumer brand to redirect capacity to enterprise and AI — a clear supply-prioritization signal.
Investor Takeaway
Micron shows how a deeply cyclical commodity business can take on growth-stock traits when a new demand driver (AI/HBM) meets constrained supply — and how multi-year contracts dampen, but never erase, cyclicality. Watch HBM share, new supply, and whether floor pricing holds.
