Micron Q3 earnings show HBM demand driving next phase of AI memory growth, with prices and volumes both accelerating.

Micron Technology (NASDAQ: MU) announced financial results for Q3 FY 2026, with revenue of $41.46 billion, up significantly from $9.30 billion year-on-year and exceeding Wall Street consensus of $35.69 billion. Cloud Memory revenue reached $13.77 billion, compared to $3.39 billion in Q3 FY 2025. Core Data Center revenue was $11.52 billion versus $1.53 billion year-on-year. Mobile and Client revenue totaled $11.52 billion against $3.26 billion in the prior year, while Automotive and Embedded revenue came in at $4.63 billion compared to $1.13 billion. The company reported adjusted operating income of $33.68 billion with an adjusted operating margin of 81.2%, versus $2.49 billion and 26.8% in the year-ago quarter. Adjusted net income was $28.86 billion, with adjusted diluted earnings per share of $25.11 against $2.18 billion and $1.91 per share year-on-year.

"Micron's record fiscal Q3 financial results and even stronger outlook for Q4 reflect the strategic value of memory in the AI era," said Sanjay Mehrotra, Chairman, President, and CEO of Micron Technology. "Micron is investing at record levels in technology, products, and supply to address our customers' rapidly growing demand. We believe our multi-year Strategic Customer Agreements will significantly enhance the durability and predictability of Micron's strong financial performance."

Micron is leveraging tight supply conditions to reshape its commercial model while accelerating its product roadmap for data center memory and storage. Strategic Customer Agreements (SCAs) establish a planning framework that aligns customer commitments with Micron's constrained supply outlook, particularly in high-performance DRAM and HBM. Concurrently, the company is signaling that greenfield ramps and higher-performance product mixes will create near-term pressure on DRAM cost per bit, even as they strengthen long-term supply positioning. The quarter also demonstrated broad-based strength across cloud memory, core data center, and mobile segments, reducing dependence on any single end market.

Micron has positioned SCAs as take-or-pay agreements that lock in multi-year volumes with pricing structured around quarterly market resets within defined ceiling and floor bands. The company described most SCAs as five-year agreements, with customer commitments supported by upfront cash deposits and related financial commitments totaling more than $22 billion, including nearly $18 billion in cash. These deposits are not treated as prepaid revenue and are scheduled to return on a predefined timeline weighted toward the second half of the contract term. Micron has also tied SCAs to multi-year demand planning for HBM3E, HBM4, and beyond, where customer requests exceed Micron's supply capacity even through calendar 2028. This structure reduces downside risk from abrupt demand shifts but simultaneously raises execution stakes around allocation and roadmap delivery, fundamentally changing how customers secure supply and how Micron prices memory.

HBM demand remains above supply for both HBM3E and HBM4, with tightness expected to persist beyond calendar 2027. Micron has raised its view of the HBM total addressable market, now expecting HBM to cross $100 billion in calendar 2027 rather than calendar 2028. The company's strategy aims to maintain HBM share in alignment with broader DRAM share over time, implying sustained focus on scaling HBM output without constraining non-HBM DRAM demand. Management has also reframed the industry's bit shipment growth as increasingly supply-determined rather than demand-determined, given persistent undersupply in both DRAM and NAND. This stance supports pricing discipline but also means customer satisfaction depends heavily on allocation choices and ramp timing, with the data center memory cycle being driven as much by manufacturing constraints as by demand signals.

Micron has emphasized SOCAM as the enabling form factor for low-power DRAM (LPDRAM) deployment in data centers, tied to growing CPU server demand and agentic AI workloads. The company has positioned itself as an early mover in both data center LPDRAM adoption and SOCAM development, expecting LPDRAM to grow as a share of data center DRAM consumption. It has also highlighted reliability, availability, and serviceability challenges when deploying LPDRAM in data centers, creating differentiation opportunities through validation, ecosystem engagement, and product tuning. This matters as CPU platform diversity expands and memory power and footprint constraints become more central to system design. SOCAM adoption would also broaden Micron's data center DRAM opportunity beyond HBM, increasing exposure to server platform transitions. Product differentiation will depend on demonstrating data center-grade reliability for components that did not originate in that environment.

For Q4 FY 2026, Micron guided revenue to $50.0 billion plus or minus $1.0 billion with adjusted gross margin of approximately 86%, adjusted operating expenses of approximately $1.65 billion, and adjusted diluted earnings per share of $31.00 plus or minus $1.00. Management described higher near-term DRAM bit cost pressure from two sources: elevated trade ratios in HBM and LPDRAM, and greenfield ramps that lack the efficiency of historical node transitions. The company expects startup costs to become more significant beginning in Q4 FY 2026 and extending into the first half of FY 2027, estimating a $100 million to $200 million per quarter effect during FY 2027 compared to prior run rates. Micron raised its FY 2026 capital spending outlook to approximately $27 billion and signaled further increases in FY 2027, with more than half of the incremental spending dedicated to construction. Supply additions from greenfield capacity are expected to contribute more meaningfully to bits in calendar 2028, though management does not anticipate supply intersecting with demand even with those improvements.

Micron's commentary points to a memory market increasingly governed by long-term capacity planning rather than traditional pricing cycles. Strategic Customer Agreements, multi-year HBM commitments, and greenfield investments signal a fundamental shift in how the industry manages supply and demand over extended planning horizons.
