Micron has provided the answer to Wall Street’s biggest concern.

```

Micron Technology released its financial results for the third quarter of fiscal year 2026 after the US stock market closed on June 24th. The stock price surged more than 16% after hours. The most eye-catching figure was a year-over-year revenue growth of about 346%, reaching $41.46 billion. Adjusted earnings per share were $25.11, up more than twelve-fold year-over-year — "adjusted" here means profit excluding non-cash and one-off items like stock-based compensation.

But for those who've been tracking this stock all year, the triple-digit growth isn't the most important part to read in this earnings report. There are two real signals: First, the core data center business that the market worried about most performed about 70% better than analysts expected; second, Micron's guidance for next quarter continues to rise. Just a day before the earnings release, Korean media reported that competitor SK Hynix was slowing its HBM4 expansion due to Nvidia's Rubin production forecast cuts. Micron plunged 13% that day, with the market concerned "whether AI memory demand is peaking." This earnings report addresses that concern head-on with actual performance.

The Data Center Business Is the Real Star

Focusing on the most sensitive area: this quarter, the core data center business earned $11.52 billion in revenue, while analysts had expected only $6.8 billion, beating expectations by about 69%. This is the most significant signal in the entire report because it addresses the panic from Tuesday—whether AI servers' appetite for memory is starting to decline.

The answer, at least for Micron, is negative. Not only data centers, but the cloud memory business posted $13.77 billion in revenue, about 29% above the expected $10.69 billion. Combined, these two segments made $25.29 billion, about 61% of total revenue. The annualized data center business revenue rate is now above $100 billion. In other words, while the market worries "AI memory orders may be slowing," Micron paints a picture of "AI and cloud demand being even stronger than Wall Street expected."

In fact, this quarter Micron outperformed market expectations in almost all metrics: revenue exceeded by about 16%, adjusted EPS by 22%, adjusted operating profit by 21%, and gross margin by 3 percentage points. Nearly seventy percent of the data center's outperformance sent a powerful signal to short sellers.

Growth Almost Entirely Driven by Price, 84.9% Gross Margin is the Foundation

Breaking down the source of growth reveals something noteworthy: this quarter's revenue surge was driven almost entirely by price increases, not by selling more units. DRAM revenue grew 67% quarter-on-quarter, but shipped bits (output) only increased by single digits, while prices rose more than 60%; NAND flash prices rose around 85% quarter-on-quarter. Volume barely moved, but money came in exponentially—this points to pricing power amid extreme supply-demand tension.

Pricing power is ultimately reflected in gross margin. Micron’s adjusted gross margin this quarter reached 84.9%, up 10 points quarter-on-quarter, more than twice last year and a company record. Operating profit margin also reached 81.2%, meaning high gross margin was fully translated into operating profit — price, capacity utilization, and product mix are all currently positioned extremely favorably for Micron.

That’s why this number is particularly critical. The memory industry is known for its cyclical swings, and such high gross margins historically mean supply and demand imbalance is at its peak, soon followed by new capacity and price drops. What the market really wants to know is: This time, can the high demand driven by AI servers, HBM, and high-capacity DRAM sustain elevated margins longer than usual? From this quarter's data, Micron's answer is yes. Below is the revenue curve from under $10 billion a year ago to over $40 billion this quarter, and next quarter’s guidance of $50 billion.

All Four Business Segments Set Records, Shortage Spreading to End Users

If only AI-related businesses were strong and traditional end users weak, markets would still worry that growth was overly concentrated and price hikes wouldn't spread. But this quarter, all four segments set records. Besides cloud memory (CMBU, revenue $13.8 billion up 78% quarter-on-quarter) and core data center (CDBU, revenue $11.5 billion up 103%), mobile and client business (MCBU) for phones and PCs also had $11.5 billion, about 18% above analysts’ expectations of $9.73 billion; auto and embedded business (AEBU) revenue was $4.6 billion, up 71% quarter-on-quarter.

The outperformance in mobile and client business is also key. It shows supply-demand tension for storage is spreading downstream from AI data centers: AI servers and high-end data centers are monopolizing advanced DRAM and HBM capacity, pushing shortages onto PC, smartphone, and gaming console DRAM and NAND as well, which supports prices. So Micron's report doesn’t say "only AI is strong," but "AI has improved supply-demand for the entire memory industry."

More Important Than Results: Next Quarter’s Guidance Still Being Upgraded

The third quarter shows demand was strong in the past quarter, but the fourth quarter's guidance determines future pricing. Micron expects Q4 revenue between $49 to $51 billion, midpoint $50 billion, clearly above analysts’ $43.2 billion expectations — about 15.6% higher. Adjusted EPS guidance is $30-32, midpoint $31, about 22% above market expectation.

This guidance matters because it directly dispels fears of "profit reaching its peak." At midpoint, Micron’s Q4 revenue is projected to grow about 20% quarter-on-quarter from $41.46 billion; EPS also has upside potential. With the stock already up nearly 270% this year and markets intolerant of surprises, merely "meeting expectations" isn't enough to keep the stock rising — the post-market surge was driven by next quarter’s strong acceleration signal. No wonder some sell-side analysts had already raised Micron’s earnings forecast ahead of the report.

Worth noting, Q4 gross margin guidance is about 86% (only a slight rise from this quarter’s 84.9%), and the company flagged that price increases will slow. This doesn’t mean a peak, but simply that with such a high base, pulling up margins purely through price gains is harder, with future growth more likely to depend on shipment volumes and product mix.

16 Long-Term Contracts and $22 Billion Deposits: Micron Is Changing Its Business Model

This report also hides a clue that might be more significant in the long run. Micron announced it has signed 16 strategic customer agreements (SCA), covering about 20% of DRAM and about one-third of NAND output, usually for five-year terms from 2026 to 2030. Most are "take-or-pay" — customers pay for the agreed volume whether or not they pick it up.

According to accounting standards, Micron disclosed its remaining performance obligations (RPO) for the first time — minimum contract revenues based on minimum shipment and price — totaling about $100 billion for signed agreements. Also notable, the company is set to receive $22 billion in cash deposits and financial commitments for these deals, with about $18 billion in cash. Management especially noted that even at the contract minimum prices, Micron’s gross margin still exceeds any previous cycle peak.

For a company in a highly cyclical industry, this matters for "visibility". Long-term contracts lock in more than half of revenues, a chunk of price and volume ahead of time, adding stable, "long contract"-style revenue to the traditional spot memory business. This is Micron’s transformation — using structural certainty to offset the industry’s inherent cyclical swings.

Supply Shortage to Extend Beyond 2027, More Capital Expenditure

More than the financial outperformance, management’s demand outlook draws attention. Micron CEO Sanjay Mehrotra said on the call that AI has become one of the most important growth drivers the memory industry has seen in decades, and the trend is still in its early stages. His key judgment: Because of AI demand across segments and structural supply limits, DRAM and NAND supply shortages are expected to persist beyond 2027, with improvement not until 2028 — "there’s no sign yet of supply catching up with demand."

This projection is more optimistic than previous market consensus, meaning the current cycle of AI infrastructure buildout may last longer than investors expected. HBM is another factor — as high-bandwidth memory paired with GPU in AI servers, directly determining computational power, Micron’s HBM4 shipments reached over $1 billion cumulatively, the speed for 12-layer products is double that of last-gen HBM3E, and 2026’s HBM capacity is basically sold out.

To meet demand, Micron is ramping up capital expenditures. It expects Q4 capex around $10 billion, higher than Wall Street's estimate of $8.9 billion. Full-year FY2026 capex about $27 billion, mainly for HBM, advanced DRAM and advanced packaging capacity. Cloud vendors like Microsoft, Amazon, Google and Meta, plus model developers like OpenAI and Anthropic, are ramping up AI infrastructure spending, with memory becoming one of the fastest-growing cost components in AI servers.

Conclusion

This earnings report is powerful with no weak links: price, profit, margin, guidance, long-term contracts, all pointing the same way. But for a stock deeply tied to the AI supercycle, two variables remain worth watching. First is the duration of the cycle: the current high margin is based on extreme supply-demand imbalance, and as new plants in Idaho and New York come online after 2027, whether price and profit margins can stay high is the long-term question. Second is valuation tolerance: after nearly 270% gain this year, the market expects Micron's every earnings report to be not just "good", but "very good, and guidance even better". It delivered this time, but the bar will keep rising.

What’s worth tracking next are the pace of long-term contract revenue consolidation, HBM supply and margin trajectory, and whether the demand-supply gap can be quantified after 2027. A strong earnings report can restore short-term confidence, but the longer-term value will ultimately depend on how long AI capex and memory shortages persist.
