Micron (MU) Q3 2026 earnings review
A Blowout Quarter, Bought at the Top of the Cycle
Micron delivered a record-shattering quarter: revenue hit $41.5B, up 346% YoY and 74% sequentially—the largest dollar increase in company history. Non-GAAP gross margin reached 84.9% and EPS was $25.11. Q4 guidance calls for $50B revenue and $31 EPS, both records. The headline news is structural: 16 new Strategic Customer Agreements lock in roughly $100B of minimum-price revenue and bring $22B in customer financial commitments. The catch—management itself flagged that price increases are now moderating, and a $31B receivables balance is the first sign that converting this boom to cash is getting harder.
🐂 Bull Case
16 multi-year Strategic Customer Agreements cover ~20% of DRAM and ~30% of NAND volume, with $100B in minimum-price revenue and $22B of customer commitments ($18B cash deposits). Management says even floor prices deliver margins well above any prior peak.
Management now expects DRAM and NAND to stay tight beyond calendar 2027—pushed out from the prior 'beyond 2026' view. New fab capacity takes years, while AI demand keeps climbing, supporting pricing far longer than a normal cycle.
🐻 Bear Case
The 86% Q4 gross margin guide reflects what management called a 'meaningful moderation in the rate of price increases.' At this altitude, incremental price yields little additional margin. Memory pricing is at or near a cyclical peak.
Receivables ballooned to $31.0B from $9.3B at fiscal year-end—a $20B nine-month drag that held operating cash flow ($45.7B) just below net income ($47.3B). Rapid revenue growth is outrunning collections.
⚖️ Verdict: 🟢
Bullish, with one eye on the exit. Results are exceptional and the SCAs add genuine durability. But the buyer is paying peak-cycle margins right as management signals price growth is slowing, and a $31B receivables build is the first crack in the cash story. Outstanding quarter; not a max-bullish entry point.
Key Themes
Strategic Customer Agreements Transform the Model
Micron signed 16 SCAs spanning data center, consumer, and auto—four very large customers, three mid-sized, the rest automotive. These take-or-pay contracts run five years (2026-2030; auto is three). 14 of the 16 carry ~$100B in cumulative minimum-price revenue, and customers are putting up $22B in commitments, ~$18B as cash deposits. The largest deals set ceiling prices at current CQ2 levels and floors that still clear prior-peak margins. When fully executed, ~40% of revenue sits under fixed or ceiling pricing.
Data Center Crosses a $100B Run Rate
Data center revenue topped $25B in the quarter—an annualized run rate above $100B. The Core Data Center unit grew 103% sequentially as agentic AI extends demand beyond accelerators into CPU and storage racks. Data center SLC revenue alone exceeded $5B, more than doubling sequentially. Management raised its calendar 2026 server-unit outlook to high-teens growth, up from low-double-digits.
DRAM and NAND Both Running on Price
DRAM revenue hit a record $31.3B (76% of total, +67% sequentially) on low-single-digit bit growth and a low-60s percent price jump. NAND hit a record $9.9B (24% of total, +99% sequentially) on mid-single-digit bit growth and a mid-80s percent price increase. Almost all of the growth is price, not volume—the defining feature of this cycle and the reason margins exploded.
Receivables Spike Outrunning Cash Collection
Receivables jumped to $31.0B from $17.3B last quarter and $9.3B at fiscal year-end—roughly tripling in nine months. The $20B build was the single largest working-capital drag in the cash flow statement and is why nine-month operating cash flow ($45.7B) came in just below net income ($47.3B). With revenue set to climb further to $50B, monitoring whether collections keep pace is essential; this is the one data point that cuts against an otherwise pristine quarter.
Margins at the Ceiling, Price Growth Slowing
The Q4 gross margin guide of ~86% is up only ~1 point from 84.9%, versus the 10-point sequential jumps seen earlier in the year. Management explicitly attributed this to a 'meaningful moderation in the rate of price increases.' At these levels, incremental pricing barely moves the margin line. This is the clearest signal that the steepest part of the pricing ramp is behind the company, even if absolute levels stay elevated.
Consumer Demand Elasticity
Management expects PC and smartphone unit volumes to decline even as industry revenue grows, because high memory prices are pricing out some buyers. Micron is steering scarce bits toward data center and high-value applications, but the admission that consumer units fall under these prices is a reminder that the pricing that drives today's margins also destroys some end demand.
Massive CapEx and Greenfield Execution Risk
FY26 capital spending is now ~$27B, with Q4 alone near $10B, and FY27 stepping up further—over half the year-over-year increase is construction. Idaho ID1 targets first wafers mid-calendar 2027, ID2 in late 2028, with New York, Japan, Singapore, and Taiwan all in flight. Delivering these greenfield projects on schedule is the gating factor for future supply; any slip pushes out the volume needed to sustain growth once price gains fade.
HBM4 Ramping Ahead of Schedule
HBM4 12-high is ramping twice as fast as HBM3E 12-high, with over $1B already shipped and mature yields expected sooner than the prior generation. Micron is deliberately holding HBM share close to its overall DRAM share—because HBM's high wafer trade ratio (over 3x and rising toward 4x for HBM4E) consumes capacity that would otherwise serve non-HBM markets. Notably, management confirmed non-HBM margins currently exceed HBM margins, a mix nuance worth watching as HBM grows.
Balance Sheet at Its Strongest Ever
Micron cut total debt to $5.7B from $14.6B at fiscal year-end, ending with a $24.4B net cash position and $30.2B in cash and investments. All three rating agencies upgraded the company this year, reaching BBB+. From December 2026, after the second anniversary of its CHIPS agreement, management intends to return 100% of excess cash to shareholders over time—a meaningful shift now that buyback restrictions ease.
Other KPIs
Accelerating, then plateauing. Non-GAAP operating margin expanded from 26.8% a year ago to 69.0% last quarter to 81.2% this quarter—a 54-point YoY swing. Every business unit posted operating margins above 60%, led by Mobile & Client at 86% (versus 15% a year ago, when that unit ran near breakeven). The operating leverage is extraordinary, but with the Q4 gross margin guide flagged as moderating, this quarter likely marks the steepest part of the climb.
A quarterly record, up from $6.9B last quarter and $1.9B a year ago. Built from $25.4B operating cash flow less $7.1B net CapEx. Crucially, this excludes SCA customer deposits, which management says flow through financing—not free cash flow—and will be returned to customers in the back half of the agreement terms. Cash and investments reached a record $30.2B.
Under ASC 606, Micron began disclosing RPO this quarter. The reported figure exceeds $5B—only the SCAs closed within Q3, with ~$1.8B of associated next-12-month revenue (mostly smaller auto deals). Once all 14-of-16 priced agreements are reflected in the Q4 10-K, RPO jumps to ~$100B. Management stressed this is a conservative minimum—based on floor volumes and floor prices—and expects actual revenue to exceed it substantially.
Guidance
Decelerating in rate, still a record. The $50B midpoint implies ~21% sequential growth, down from this quarter's 74% pace—a natural slowing off a vastly larger base. It would mark a sixth consecutive quarterly revenue record.
The midpoint implies ~23% sequential growth from $25.11, slightly outpacing revenue growth as margins tick up. Based on ~1.15B diluted shares.
Decelerating expansion. Up roughly 1 point from 84.9%, versus the 10-point jumps of recent quarters. Management directly attributed the smaller step to a moderation in the rate of price increases—the key tell that pricing momentum is cooling even as levels stay high.
Operating expenses will rise about $1B in fiscal 2027 to fund R&D, weighted to the second half. FY26 CapEx lands near $27B (Q4 ~$10B), and FY27 quarterly CapEx runs above Q4 levels, with more than half the year-over-year increase coming from construction as Micron pulls in clean-room capacity. Spending is rising into a period of slowing price gains—a setup that pressures near-term free cash flow conversion.
Key Questions
Receivables and Cash Conversion
Receivables tripled to $31B in nine months while operating cash flow fell just short of net income. As revenue climbs to $50B, what is the expected collection cadence, and is any customer concentration or extended payment term driving this build?
Margin Path Beyond the Peak
With Q4 gross margin guided up only ~1 point and price increases moderating, what does a normalized margin look like once the SCA floor-price volumes layer in and new greenfield capacity ramps in 2027-2028?
SCA Downside Protection
Management repeatedly declined to specify whether the SCAs contain margin floors or only price floors. In a downturn, what specifically protects Micron's profitability—volume take-or-pay, price floors, or both—and how enforceable are the cancellation terms?
HBM Margin Convergence
Non-HBM margins currently exceed HBM margins. As HBM grows toward a larger share of DRAM, what is the path to closing that gap, and does the rising HBM trade ratio create a structural mix headwind to blended margins?
