The key question troubling Wall Street has found its answer from Micron Technology. On June 24, after the U.S. market closed, Micron Technology (NASDAQ: MU) released its results for the third quarter of fiscal 2026, with its stock price surging more than 16% in after-hours trading. The most eye-catching figures on the surface were revenue, which soared approximately 346% year-over-year to $41.46 billion, and adjusted earnings per share of $25.11, an increase of over 12 times year-over-year. The adjusted figures represent operating profitability after excluding non-cash and one-time items like stock-based compensation.
However, for those who have followed this stock closely all year, triple-digit growth rates are not the most critical part of this earnings report. The real signals are twofold: first, the core data center business, which was the market's greatest worry, delivered revenue that exceeded analyst expectations by about 70%; second, the company's guidance for the next quarter continues to trend upward. Just one day before the earnings release, South Korean media reported that competitor SK Hynix was slowing its HBM4 capacity expansion due to lowered production expectations for Nvidia's Rubin, causing Micron's stock to plunge 13% that day. The market's fear was precisely whether "AI memory demand is starting to peak." This earnings report effectively counters that concern with solid performance.
Data Center Takes Center Stage in This Report
Focusing on the market's most sensitive area: core data center business revenue for the quarter was $11.52 billion, while analysts had previously expected only $6.8 billion, an outperformance of approximately 69%. This is the most significant signal in the entire report because it directly addresses the core concern behind Tuesday's panic—whether AI servers' appetite for memory is diminishing.
The answer, at least from Micron, is a resounding no. It's not just the data center; cloud memory business revenue of $13.77 billion also surpassed expectations of $10.69 billion by about 29%. Combined, these two segments totaled $25.29 billion, accounting for about 61% of the company's total revenue, with the corresponding data center business now running at an annualized revenue rate exceeding $100 billion. In other words, while the market worried that "AI memory orders might be faltering," Micron paints a picture of "AI and cloud demand being even stronger than Wall Street anticipated."
In fact, Micron exceeded market expectations across nearly all metrics this quarter: revenue was about 16% higher, adjusted EPS about 22% higher, adjusted operating profit about 21% higher, and gross margin 3 percentage points higher. The nearly 70% outperformance in the data center segment was the decisive blow against the bearish narrative.
Growth Driven Almost Entirely by Price, with 84.9% Gross Margin as the Foundation
Examining the source of growth reveals a notable fact: the explosive revenue increase this quarter came almost entirely from price hikes rather than selling more units. DRAM revenue grew 67% sequentially, but bit shipments increased only in the single digits, while prices rose just over 60% sequentially. For NAND flash, prices increased about 85% sequentially. Volume remained largely flat, yet revenue doubled, reflecting pricing power under conditions of extreme supply-demand tightness.
This pricing power ultimately manifests in gross margin. Micron's adjusted gross margin for the quarter reached 84.9%, a 10 percentage point increase sequentially, more than double the level from a year ago, setting a company record. Operating margin similarly reached 81.2%, indicating that high gross margins are almost fully translating into operating profit—price, capacity utilization, and product mix are all currently positioned extremely favorably for Micron.
This is why this number is particularly crucial. The memory industry is notoriously cyclical, and historically, such high gross margins often signal that supply-demand imbalance has peaked, soon to be followed by new capacity influx and price declines. What the market truly wants to know is whether demand from AI servers, HBM, and high-capacity DRAM can sustain these high margins longer than in previous cycles. Based on this quarter's data, Micron's answer appears affirmative.
All Four Business Segments Set Records, Shortage Spreading to End Markets
If only AI-related businesses were strong while traditional end markets remained weak, the market would still worry that this growth cycle is too concentrated and price increases might not diffuse. However, this quarter saw all four business segments achieve record results. Beyond the previously mentioned cloud memory (CMBU, revenue $13.8 billion, up 78% sequentially) and core data center (CDBU, revenue $11.5 billion, up 103% sequentially), the mobile and client business (MCBU) serving smartphones and PCs also generated $11.5 billion in revenue, exceeding analyst expectations of $9.73 billion by about 18%. The automotive and embedded business (AEBU) revenue was $4.6 billion, up 71% sequentially.
The outperformance in the mobile and client segment is equally important. It indicates that the memory supply-demand tightness is spreading from AI data centers to broader downstream markets: AI servers and high-end data centers are consuming advanced DRAM and HBM capacity, creating a squeeze that tightens supply for standard DRAM and NAND used in PCs, smartphones, and gaming consoles, thereby supporting prices. Thus, Micron's report conveys not "only AI is strong," but that "AI is driving an improvement in the supply-demand structure across the entire memory industry."
Guidance for the Next Quarter Remains More Critical Than Current Results
The third-quarter data proves that demand was strong in the past quarter, but the guidance for the fourth quarter determines how the market prices the future. Micron forecasts fourth-quarter revenue between $49 billion and $51 billion, with a midpoint around $50 billion, significantly above the analyst consensus of $43.2 billion, representing an outperformance of about 15.6% at the midpoint. Adjusted EPS guidance is $30 to $32, with a midpoint of $31, about 22% above market expectations.
The weight of this guidance lies in its direct refutation of concerns that "profits may be nearing a peak." At the midpoint, Micron's fourth-quarter revenue would grow approximately 20% sequentially from the current quarter's $41.46 billion, with EPS also having further upside potential. Against a backdrop where the stock has already surged nearly 270% year-to-date and market tolerance for error is extremely low, merely "meeting expectations" is insufficient to drive the stock higher. What propelled the after-hours surge was the strong signal of further profit acceleration in the next quarter. It's no wonder some sell-side analysts had already raised their profit forecasts for Micron prior to the earnings release.
It should be noted that the fourth-quarter gross margin guidance of approximately 86% is only a slight increase from the current quarter's 84.9%, and the company indicated that price increases will moderate. This does not signal a peak but rather suggests that, from an already high base, the room for gross margin expansion purely from price hikes is narrowing, with future increments relying more on shipment volume and product mix.
16 Long-Term Agreements and $22 Billion in Guarantees: Micron Rewriting Its Business Model
Hidden within this report is another clue, potentially more profound though overshadowed by triple-digit growth rates. Micron announced it has signed 16 strategic customer agreements (SCAs), covering approximately 20% of its DRAM shipments and about one-third of its NAND shipments, typically spanning five years from 2026 to 2030. Most of these agreements are "take-or-pay" long-term contracts, meaning customers must pay for agreed volumes regardless of whether they take delivery.
Under accounting rules, Micron disclosed its remaining performance obligation (RPO) for the first time this quarter, representing the minimum contractual revenue based on committed volumes and minimum prices. The RPO for currently signed agreements is approximately $100 billion. More notably, the company will receive about $22 billion in cash deposits and related financial commitments, with roughly $18 billion in cash deposits. Management specifically emphasized that even at the minimum prices stipulated in the agreements, Micron's gross margins would still be higher than the peak of any previous cycle.
For a company in a highly cyclical industry, the significance lies in "visibility." These long-term agreements lock in over half of the company's revenue, along with a significant portion of pricing and volume, effectively adding a layer of stable, "long-term contract" income on top of the traditional spot-market memory business. This is precisely the transformation Micron seeks—using structural certainty to hedge against the inherent cyclical volatility of the memory industry.
Supply Tightness Extended Beyond 2027, with Further Capital Expenditure Increases
Even more noteworthy than the better-than-expected financial figures is management's outlook on demand prospects. Micron CEO Sanjay Mehrotra stated on the earnings call that AI has become one of the most significant growth drivers for the memory industry in decades, and this trend remains in its very early stages. His key assessment is that, driven by combined AI demand across market segments and structural supply constraints, tight supply-demand conditions for DRAM and NAND are expected to persist beyond 2027, with supply gradually improving only in 2028, and "we currently do not see when supply will catch up with demand."
This outlook is more optimistic than previous market expectations, suggesting that this AI infrastructure build-out cycle may last longer than investors initially anticipated. This view is further supported by the HBM trajectory—as the high-bandwidth memory paired with GPUs in AI servers, directly determining computing power limits, Micron's HBM4 shipments have cumulatively exceeded $1 billion, with the ramp-up speed for its 12-layer stacked product being twice that of the previous generation HBM3E. HBM capacity for 2026 is also largely sold out.
To meet this demand, Micron continues to increase capital expenditures. The company expects fourth-quarter capital expenditures of approximately $10 billion, above Wall Street's expectation of about $8.9 billion, with full-year fiscal 2026 capital expenditures around $27 billion. New investments are primarily directed towards HBM, advanced DRAM, and advanced packaging capacity. Cloud providers like Microsoft, Amazon, Google, and Meta, as well as model developers like OpenAI and Anthropic, are continuously increasing AI infrastructure investments, with memory becoming one of the fastest-growing cost components in AI server builds.
Conclusion
The strength of this earnings report lies in its lack of weaknesses: price, profit, gross margin, guidance, and long-term agreements all point in the same positive direction. However, for a stock already deeply tied to the AI supercycle narrative, two variables warrant continued monitoring. First is the duration of the cycle: current high gross margins are built on extreme supply-demand tightness; as new fab capacities in Idaho and New York gradually come online post-2027, whether prices and margins can remain elevated is a long-term core question. Second is valuation tolerance: after a nearly 270% year-to-date gain, the market's requirement for each of Micron's earnings reports is no longer "good," but "excellent, with even better guidance." This time, it delivered, but the bar will be set higher each quarter.
Going forward, it will be worth tracking the quarterly recognition of long-term agreement revenue, the supply and margin trajectory for HBM, and the quantification of the supply-demand gap beyond 2027. A strong earnings report can restore short-term confidence, but longer-term value ultimately depends on how long AI capital expenditures and memory shortages persist.
