Key Highlights

  • Fiscal Q3 2026 revenue was $41.456 billion, up 346% year over year and 74% sequentially, with GAAP diluted EPS of $24.67 and non-GAAP diluted EPS of $25.11.
  • Management guided fiscal Q4 2026 revenue to $50.0 billion plus or minus $1.0 billion at about 86% gross margin, while flagging "meaningful moderation in the rate of price increases."
  • At $900.20 at last closing the stock sits about 28% below its 52-week high of $1,255.00, on a trailing price-to-earnings ratio near 20.
  • Memory has always mean-reverted, and management itself flagged moderating price increases.

Why Micron Stock Is in Focus

Micron (NASDAQ:MU) is the only US-headquartered maker of both DRAM and NAND flash at scale, and memory has become the binding constraint on artificial-intelligence build-outs. The result is one of the sharpest earnings expansions in semiconductor history. All market data here was observed at the close; multiples move continuously.

The Latest Verified Development

The most recent reported period is fiscal Q3 2026, the quarter ended, and furnished to the SEC as Exhibit 99.1 to an 8-K. Micron's fiscal year ends in late August. The company had not published its fiscal Q4 and full-year call date; the fiscal 2025 equivalent came.

What the Trading Activity Actually Shows

The working premise was that Micron "dominates" Nasdaq dollar volume; market data supports a narrower version. At last closing Micron traded 47,004,796 shares at a $900.20 close, approximately $42.3 billion of notional turnover by this calculation. Nvidia traded 154.3 million shares at $196.51, about $30.3 billion; Tesla and Broadcom were far lower. Micron therefore led the Nasdaq that session, but "dominates" overstates a one-day, closing-price-based estimate rather than an exchange-audited ranking.

Recent Financial Performance

Fiscal Q3 2026 revenue was $41.456 billion, against $23.860 billion in fiscal Q2 2026 and $9.301 billion in fiscal Q3 2025. GAAP gross margin was 84.6% and non-GAAP 84.9%. GAAP operating income was $33.318 billion, an 80.4% margin; non-GAAP was $33.681 billion, or 81.2%. GAAP net income reached $28.243 billion and non-GAAP $28.857 billion.

For all of fiscal 2025, Micron generated $37.38 billion of revenue, 39.8% GAAP gross margin and $7.59 of GAAP diluted EPS. One fiscal 2026 quarter now exceeds that full prior year. Nine-month fiscal 2026 revenue was $78.959 billion.

Business Model and Principal Assets

Micron reports four business units. In fiscal Q3 2026: Cloud Memory $13.769 billion, Core Data Center $11.524 billion, Mobile and Client $11.521 billion, Automotive and Embedded $4.634 billion. By technology, DRAM contributed $31.328 billion (75.5% of revenue), NAND $9.943 billion (24.0%) and other $185 million. Principal assets are fabs in the US, Japan, Singapore and Taiwan, plus assembly and test sites.

The HBM and AI-Memory Opportunity

On the fiscal Q3 call, management said the HBM4 12-high volume ramp is "tracking twice as fast as HBM3E 12-high," with more than $1 billion of HBM4 revenue already shipped, and described DRAM and NAND tightness persisting "beyond calendar 2027." Data center revenue exceeded $25 billion in the quarter, an annualized rate above $100 billion.

Micron has signed 16 strategic customer agreements covering roughly 20% of DRAM volume and a third of NAND volume through 2030; fourteen carry minimum pricing commitments totaling about $100 billion, and roughly 40% of revenue now sits under fixed or ceiling pricing. These are company statements, not independently verified contract terms. Analytically, ceilings set at current market prices cap upside as much as floors protect downside.

Capital Expenditure and Supply

Management guided fiscal 2026 capital expenditure to approximately $27 billion net of government incentives, including about $10 billion in fiscal Q4, and said fiscal 2027 quarterly capex would run above fiscal Q4 2026 levels, more than half the increase coming from construction. Nine-month fiscal 2026 capex was $19.602 billion.

Idaho's ID1 fab targets first wafer output in mid-calendar 2027 and ID2 in late calendar 2028; New York broke ground in January 2026; Manassas, Virginia began 1-alpha DDR4 production. The Commerce Department finalized $6.44 billion in direct CHIPS funding across the Idaho, New York and Virginia projects, and Micron recognized $2.989 billion of government incentives over nine months of fiscal 2026. Amendments to the Idaho and New York funding agreements were exhibits to the fiscal Q3 10-Q.

The depreciation overhang

Depreciation and amortization was $2.364 billion in fiscal Q3 2026, only 5.7% of revenue, a ratio flattered by the revenue spike. The $27 billion annual capital budget converts into depreciation later, a fixed cost that persists after pricing normalizes.

Customer Concentration

Micron's fiscal Q3 2026 10-Q discloses one customer at approximately 10% of revenue in the nine months ended down from 16% a year earlier, a broader revenue base, not a lost account. Concentration still matters: hyperscalers and a few accelerator vendors sit behind most HBM demand.

China Exposure and Export Restrictions

China's Cyberspace Administration barred Micron products from critical information infrastructure in 2023. Reuters reported in October 2025 that Micron would exit China's server chip business, having failed to recover from that ban, while continuing to serve automotive, mobile and selected multinational customers. Reuters put mainland China at about $3.4 billion, roughly 12% of revenue, in the then-latest fiscal year.

Separately, the Bureau of Industry and Security's rule of imposed controls on HBM exports to China, covering US-origin and certain foreign-produced HBM, alongside 140 Entity List additions. Micron's China exposure is therefore structurally capped at the high-value end.

Competitive Position

TrendForce data for calendar Q1 2026 put industry DRAM revenue at $97 billion, up 81% sequentially: Samsung $37.32 billion (38.5% share), SK hynix $27.98 billion (28.8%) and Micron $21.75 billion (22.4%). Micron is thus the third-largest DRAM supplier by revenue and in HBM faces an SK hynix franchise with early Nvidia leadership. Samsung, SK hynix/Solidigm, Kioxia and SanDisk contest NAND.

Growth Opportunities

Management expects calendar 2026 industry DRAM bits to grow in the low-to-mid 20% range at prices up in the low-60s percent, and NAND bits up about 20% at prices up in the mid-80s percent. Growth levers include HBM4 share gains, high-capacity server modules, data-center LPDRAM, and eventual Idaho and New York capacity.

Balance Sheet, Free Cash Flow and Capital Returns

Micron ended fiscal Q3 2026 with $30.128 billion in cash and investments against $5.722 billion of total debt. Quarterly operating cash flow was $25.388 billion, capex $7.084 billion and adjusted free cash flow $18.304 billion. Capital returns stayed modest: $650 million of buybacks and a $0.15 quarterly dividend.

Valuation and Investor Expectations

At $900.20, market capitalization was about $1.02 trillion, roughly 20 times trailing EPS of $44.31 and about 11 times trailing revenue of $90.27 billion. Enterprise value, net of cash, is near $995 billion. Data-provider figures put the forward multiple near six times. That gap is the debate: a trailing multiple built on peak-cycle earnings understates risk, because in memory the denominator can halve. Fiscal 2025 GAAP EPS of $7.59 shows the range.

Cyclicality and Risks to the Thesis

Memory has always mean-reverted, and management itself flagged moderating price increases. Risks include supply additions from all three DRAM makers, pricing ceilings under the strategic agreements, a rising depreciation base, customer concentration, export-control tightening and any deceleration in hyperscaler capital expenditure. The 52-week range of $103.38 to $1,255.00 shows how violently this equity re-rates.

Conclusion

The verified record is exceptional: record revenue and margins, contracted volume through 2030, genuine Nasdaq dollar-volume leadership. The unresolved question is duration, not magnitude. A 28% drawdown from the peak suggests markets already discount normalization. Whether HBM is underestimated turns on whether tightness extends beyond calendar 2027, something no filing can yet confirm.
