Key points:
- Micron delivered fiscal Q3 2026 revenue of $41.5 billion, up 346% year over year, while its non-GAAP gross margin reached a company-record 84.9%.
- The company expects its momentum to continue in fiscal Q4 2026, guiding for approximately $50 billion in revenue, an 86% gross margin, and non-GAAP diluted earnings of about $31 per share.
- Data covering fiscal 2016–2026 highlights Micron’s historical cyclicality, with large swings in revenue growth and gross margins.
- Micron expects fiscal 2026 capital expenditure of approximately $27 billion and plans to increase quarterly spending further in fiscal 2027.
- Long-term customer agreements and higher production capacity may make future performance more durable, but they do not eliminate the risk of margin compression if memory prices eventually decline.
Micron Technology has delivered an extraordinary financial acceleration in fiscal 2026, driven by tight memory supply and rapidly expanding demand associated with artificial intelligence.
In this article, we examine Micron’s fiscal Q3 2026 results and near-term outlook. We then place the latest numbers in the context of the company’s volatile revenue and margin history. Finally, we assess Micron’s rising capital expenditure and the extent to which its global capacity expansion supports the argument that memory demand has shifted to a structurally higher level.
Micron’s Financial Performance
To evaluate the effect of strong AI-related demand on Micron’s bottom line, we begin with the company’s latest financial results.
Micron’s fiscal year ends in late August. Its fiscal Q3 2026 results therefore cover the quarter that ended on May 28, 2026. Unless otherwise stated, the quarterly operating figures discussed below are presented on a non-GAAP basis.
Fiscal Q3 2026 Financial Results
Micron reports results across four principal business units: Cloud Memory, Core Data Center, Mobile and Client, and Automotive and Embedded.
Cloud Memory accounted for approximately 33% of fiscal Q3 revenue, Core Data Center for 28%, Mobile and Client for 28%, and Automotive and Embedded for 11%.
Table 1: Financial performance across business units
| Business unit | Fiscal Q3 2026 revenue | Fiscal Q2 2026 revenue | Fiscal Q3 2025 revenue | Q3 2026 gross margin | Q3 2026 operating margin |
|---|---|---|---|---|---|
| Cloud Memory | $13.769 billion | $7.749 billion | $3.386 billion | 83% | 78% |
| Core Data Center | $11.524 billion | $5.687 billion | $1.530 billion | 87% | 83% |
| Mobile and Client | $11.521 billion | $7.711 billion | $3.255 billion | 87% | 86% |
| Automotive and Embedded | $4.634 billion | $2.708 billion | $1.127 billion | 79% | 75% |
Micron generated total revenue of $41.456 billion, up 346% year over year. All four business units recorded strong sales growth, with Core Data Center producing the largest increase against the prior-year quarter.
The combination of revenue growth and operating leverage produced an even larger increase in profitability. Non-GAAP operating income rose from $2.490 billion in fiscal Q3 2025 to $33.681 billion in fiscal Q3 2026—an increase of approximately 1,253%. Non-GAAP diluted earnings reached $25.11 per share, up 1,215% from $1.91 in the prior-year period.
Higher selling prices were the main contributor to the improvement. On a sequential basis, DRAM average selling prices increased in the low-60% range, while NAND prices rose in the mid-80% range. Micron attributed the increases to tight industry conditions and, particularly for NAND, a favorable product mix.
As a result, Micron’s non-GAAP gross margin reached 84.9%, compared with 39.0% in the prior-year quarter. The company described the result as a new record.
Fiscal Q4 2026 Outlook
Micron expects its strong momentum to continue in fiscal Q4 2026.
The company forecasts revenue of approximately $50 billion, plus or minus $1 billion. At the midpoint, this would represent year-over-year growth of approximately 342%, only slightly below the rate achieved in fiscal Q3.
Micron also expects its gross margin to rise further to approximately 86%.
Table 2: Fiscal Q4 2026 outlook
| Indicator | Fiscal Q3 2026 result | Fiscal Q4 2026 guidance |
|---|---|---|
| Revenue | $41.456 billion | $50.0 billion ± $1.0 billion |
| Gross margin | 84.9% | Approximately 86% |
| Operating expenses | $1.518 billion | Approximately $1.65 billion |
| Diluted earnings per share | $25.11 | $31.00 ± $1.00 |
| Diluted shares | 1.149 billion | Approximately 1.15 billion |
| Tax rate | 14.9% | Approximately 15% |
| Capital expenditure | $7.084 billion | Approximately $10 billion |
Revenue at the midpoint of the guidance range would increase by approximately 21% sequentially, while operating expenses are expected to rise by about 9%. This implies another quarter of strong operating leverage.
Micron expects non-GAAP diluted earnings of approximately $31 per share, plus or minus $1. At the midpoint, this would represent an increase of roughly 923% from the $3.03 reported in fiscal Q4 2025.
The fiscal Q4 comparison should be interpreted with some care because fiscal 2026 is a 53-week year, compared with 52 weeks in fiscal 2025. Micron has said that fiscal Q4 operating expenses will reflect an additional workweek.
Beyond fiscal Q4, investors will pay close attention to the effect of rising research and development spending. Micron expects operating expenses to increase by approximately $1 billion in fiscal 2027, with most of the increase weighted toward the second half of the year.
One development that could make Micron’s future results more durable is the introduction of long-term strategic customer agreements. The company had signed 16 such agreements by the fiscal Q3 earnings announcement. These generally include binding purchase commitments, supply assurances and, in some cases, pricing floors and ceilings.
The agreements signed so far cover approximately 20% of Micron’s DRAM volume and one-third of its NAND volume over their applicable terms. While they do not remove the effects of the memory cycle, they may improve demand visibility and reduce Micron’s exposure to purely spot-driven purchasing behavior.
Revenue and Margin Backdrop
Micron argues that AI has structurally transformed the memory industry. The company expects demand to continue exceeding supply beyond calendar 2027, with supply growth constrained by long construction lead times, limited cleanroom availability and the increasing manufacturing complexity of advanced memory products.
Nevertheless, Micron has historically been a highly cyclical company. Examining its revenue and gross-margin record over the past decade helps place the current performance in context.
Table 3: Revenue and gross-margin developments, fiscal 2016–2026
| Period | GAAP gross margin | Revenue growth year over year |
|---|---|---|
| Q4 2026 guidance | Approximately 86% | Approximately 342% |
| Q3 2026 | 85% | 346% |
| Q2 2026 | 74% | 196% |
| Q1 2026 | 56% | 57% |
| Fiscal 2025 | 40% | 49% |
| Fiscal 2024 | 22% | 62% |
| Fiscal 2023 | -9% | -49% |
| Fiscal 2022 | 45% | 11% |
| Fiscal 2021 | 38% | 29% |
| Fiscal 2020 | 31% | -8% |
| Fiscal 2019 | 46% | -23% |
| Fiscal 2018 | 59% | 50% |
| Fiscal 2017 | 42% | 64% |
| Fiscal 2016 | 20% | -23% |
Micron’s results have consistently reflected high operating leverage and substantial changes in annual revenue. Fiscal 2020 was the only year in the period shown in which the year-over-year revenue change remained within single digits.
Periods of high revenue growth have generally coincided with significant margin expansion. This relationship is visible in fiscal 2017–2018 and, more recently, in fiscal 2024–2026.
The reverse is also true. Revenue contractions in fiscal 2019 and fiscal 2023 were accompanied by severe margin compression. In fiscal 2023, Micron recorded a negative full-year gross margin as falling prices, weak demand and inventory-related charges weighed on performance.
The historical record therefore supports two conclusions. First, Micron has a large fixed-cost base, which produces substantial changes in profitability as revenue and pricing move. Second, the current margin level is far outside the company’s experience over the preceding decade.
With Micron expecting a gross margin of approximately 86% in fiscal Q4 2026, its financial performance is entering genuinely uncharted territory.
The bullish interpretation is that AI-related demand, structural supply constraints and long-term customer agreements have changed the economics of the memory industry. The bearish interpretation is that exceptionally high margins signal that the current cycle is approaching its peak and will eventually attract enough new supply to weaken prices.
Micron’s long-term agreements may moderate some of this volatility, but they do not make the company immune to lower prices, customer concentration, execution risks or changes in end-market demand.
Surging Capital Expenditure
Micron is using its strong cash generation to accelerate investment in technology, manufacturing capacity and advanced packaging.
The company recorded approximately $7.1 billion in net capital expenditure during fiscal Q3 2026 and expects spending to rise to around $10 billion in fiscal Q4. That would bring full-year fiscal 2026 capital expenditure to approximately $27 billion.
Micron expects quarterly capital expenditure in fiscal 2027 to exceed the fiscal Q4 2026 level. More than half of the anticipated year-over-year increase will relate to construction as the company brings forward cleanroom capacity intended to serve long-term demand.
The company is expanding its manufacturing footprint across several markets:
- United States: Construction is progressing at Micron’s Idaho sites, with initial wafer output from the first new fab expected in mid-calendar 2027 and from the second in late calendar 2028. Micron also broke ground on its first New York fab in January 2026.
- Taiwan: Micron expects meaningful shipments from the existing fab at its newly acquired Tongluo site in mid-calendar 2027 and has begun construction of a second cleanroom.
- Singapore: The company expects its advanced-packaging facility to contribute meaningfully to HBM packaging capacity beginning in the first half of calendar 2027.
- Japan: Construction activities supporting Micron’s manufacturing expansion remain on schedule.
- India: Micron commenced commercial shipments from its new assembly-and-test facility during fiscal Q2 2026.
TenderAlpha Pro data provides additional operational context for the India expansion. Our Micron B2B supply-chain analysis found that 906 of 1,006 observed buyer-side transactions in which Micron was the buyer and India was the import country occurred in 2025.
The concentration is consistent with a substantial procurement ramp ahead of the facility’s opening, potentially involving facility preparation, production-line setup, testing capabilities and early operational readiness. The transaction data provides evidence of sourcing and preparation activity; it should not be interpreted as a direct measure of production volumes.
The same data also shows Japan as the leading observed origin country in Micron’s buyer-side transactions with a U.S. final destination, accounting for 43.7% of those records. India represented 26.0%, while Taiwan accounted for 11.7%.
Micron has stressed that its investment approach will remain disciplined and responsive to changes in demand. Nevertheless, the scale and timing of its plans show that management expects the current expansion in memory consumption to extend well beyond fiscal 2026.
Greater production volumes and long-term supply commitments could provide some protection if average selling prices moderate. However, higher capacity will not fully offset a severe pricing downturn, particularly given Micron’s fixed-cost intensity and the additional depreciation associated with its large capital program.
Conclusion
Micron delivered record revenue, gross margins and earnings in fiscal Q3 2026, while its fiscal Q4 guidance points to another substantial step up in financial performance.
The company’s history still warrants caution. Micron has repeatedly experienced sharp revenue contractions and margin compression after periods of strong pricing and capacity investment.
This cycle may prove more durable because AI is increasing the amount and strategic importance of memory used across data centers and other end markets. Tight supply, long construction timelines and multi-year customer agreements also provide support for Micron’s argument that the structure of the industry is changing.
At the same time, the company is committing unprecedented amounts of capital to expanding supply. The success of those investments will depend not only on production execution, but also on whether demand remains strong enough to absorb the additional capacity without triggering another major decline in memory prices.
