The setup
This is the print the whole memory complex had been pricing toward — and the one this newsletter flagged a week out, when no vendor wanted to move ahead of it. Micron walked in with the bar already at the ceiling: the stock had roughly tripled off its 2025 base, sell-side targets had been marched into four figures, and UBS's Tim Arcuri had nearly tripled his target to $1,625, arguing HBM's supply-demand gap is structurally durable enough to earn an AI-adjacent multiple. When expectations are that stretched, a merely good print disappoints. This one cleared the high end of guidance on revenue, margin, and EPS — and then guided the next quarter ~16% above the Street (~$50B vs. ~$42.9B consensus). Shares closed near $1,075 and traded up roughly 13% after hours toward $1,216. Unverified to the tick.
Micron is the only U.S.-based maker of DRAM, NAND, and HBM at scale — the domestic leg of a three-supplier oligopoly alongside Samsung and SK hynix. Like a fab rather than a packager, it captures the price move at the source. The fiscal third quarter (ended late ) is the quarter in which two things converged: the AI memory shortage hit full force, and Micron formalized a new commercial structure designed to outlast the cycle that created it.
The numbers
Fiscal Q3 revenue was $41.5B, up 74% sequentially and 346% year-on-year — the fifth straight quarterly record. The $17.6B sequential dollar increase is the largest in company history, itself eclipsing last quarter's $10.2B record gain. DRAM revenue was a record $31.3B (76% of the total, +343% YoY, +67% QoQ), with bit shipments up only low-single-digits while prices rose in the low-60s percent range — a price-led quarter, the signature of genuine shortage rather than a volume ramp. NAND revenue was a record $9.9B (24%, +361% YoY, +99% QoQ), prices up in the mid-80s percent range.
Consolidated gross margin reached a record 84.9%, up 10 points sequentially; operating margin was 81.2% on $33.7B of operating income; non-GAAP EPS landed at $25.11 (+106% QoQ) against a ~$19.15 guide. Free cash flow was a record $18.3B ($25.4B operating cash flow, $7.1B capex). The balance sheet is the strongest in the company's history: cash and investments of $30.2B, net cash of $24.4B after a $4.4B debt reduction, and a BBB+ upgrade from all three agencies this year. By unit: Cloud Memory $13.8B (83% GM), Core Data Center $11.5B (87% GM), Mobile & Client $11.5B (87% GM), Auto & Embedded $4.6B (79% GM). Data-center revenue alone exceeded $25B — a >$100B annualized run-rate — and data-center SSD revenue topped $5B, more than doubling sequentially.
Guidance reinforces it: FQ4 revenue of ~$50B ±$1B, gross margin of ~86%, and EPS of ~$31 ±$1 — every one a record. FY26 capex is set at ~$27B (~$10B in FQ4), rising further in FY27 with the increase weighted to construction.
