Micron Technology, Inc. is a premier US-based semiconductor company and the lone American survivor in the global DRAM oligopoly. The company designs, develops, and manufactures advanced memory and storage solutions—spanning DRAM, High Bandwidth Memory (HBM3E, HBM4), and NAND Flash storage (including enterprise SSDs)—organized across four business segments: Cloud Memory (CMBU), Core Data Center (CDBU), Mobile & Client (MCBU), and Automotive & Embedded (AEBU).

• US Geopolitical Premium & Greenfield Diversification: Sole US-headquartered manufacturer of advanced DRAM/NAND, backed by federal CHIPS Act subsidies and committing >$267B through 2030 (and >$250B by 2035) for greenfield fab expansions in Idaho, New York, Singapore, and India, de-risking global supply from East Asian geopolitical concentration.
• Strategic Customer Agreements (SCAs): Revolutionized memory contracting via 16 non-cancelable, "take-or-pay" multi-year SCAs (including its first 5-year agreement) backed by >$22B in upfront cash deposits, pushing total Remaining Performance Obligations (RPO) to ~$100B. SCAs cover ~20% of DRAM and ~33% of NAND volume with guaranteed margin floors exceeding peak margins of prior historical cycles.
• HBM4 Architecture & Lead Customer Allocation: HBM4 (built on 1-beta DRAM) is shipping in volume for NVIDIA Corporation's Rubin platform with >60% bandwidth increase over HBM3E; HBM4 12-High is ramping twice as fast as HBM3E 12-High (> $1B revenue run-rate), with next-gen HBM4E (1-gamma DRAM) entering volume production in CY27.

• Memory Supercycle Inflection & Structural Scarcity (08/31/2026): Memory has transitioned from a cyclical commodity to the primary capital-expenditure gatekeeper for AI hyperscale expansion. HBM3E/HBM4 consumes >3x the wafer volume of standard DDR5, creating cascading industry-wide supply shortages across server, PC, mobile, and automotive DRAM. Standard DRAM spot prices are up >10x from prior cycle troughs, enabling MU to operate at near ~80% operating margins into 2028.
• Broad-Based Pricing Power Across All Four Units (08/31/2026): In the May-Q, gross margins expanded 9–13 percentage points sequentially across all business units: Core Data Center (87%), Mobile & Client (87%), Cloud Memory (83%), and Automotive & Embedded (79%), with data center SSD quarterly revenue hitting $5B. Micron can only meet 50%–65% of demand across major customer accounts.
• Binding Bottleneck for AI Accelerators (08/26/2026): Customer NVIDIA Corporation confirmed memory availability as its primary supply constraint on its FQ2 FY2027 call, committing $279B to supply chain prepayments and absorbing input costs before price increases, underscoring unprecedented memory pricing leverage.

• ⚠️ Multi-Year Capex Surge: Capex in FY27 expected in the mid-$40Bs (exceeding consensus of ~$38B) driven by Idaho and New York greenfield fab construction, which could introduce short-term FCF yield volatility.
• ⚠️ CXMT Standard DRAM Encroachment: China's ChangXin Memory Technologies (CXMT) expanded to ~7% global DRAM market share; while structurally blocked from EUV/HBM, aggressive DDR4/DDR5 capacity additions pose pricing risks if Big Three capacity ever rotates back from HBM.
• ⚠️ Customer Concentration: Hyperscaler concentration remains elevated; any future moderation in AI infrastructure monetization or hyperscaler capex pause could impact memory pricing power post-2028.
• ⚠️ Supply Chain & Foundry Dependency: Lacks captive logic foundry capacity, remaining reliant on Taiwan Semiconductor Manufacturing Co. for logic base dies and CoWoS advanced packaging.
