Some earnings reports make you check twice whether a decimal point slipped. Micron Technology delivered one of those after the U.S. close on Wednesday: $54.23 billion in revenue for a single quarter, up from $11.32 billion a year earlier. An adjusted gross margin of 87.0%. GAAP net income of $37.7 billion — more than three times what the company booked in total revenue in the same quarter of 2025. And guidance for $61.5 billion in the current quarter, roughly $4.5 billion above what Wall Street had penciled in.
The stock’s response: almost nothing. Micron jumped in the first minutes of after-hours trading, then gave the gain back within the hour and spent the evening hovering around flat, a few tenths of a percent up or down depending on the print. Thursday morning in Asia looked very different. Japan’s Nikkei 225 rallied 2.8% to 68,604. Chip tester Advantest climbed nearly 8%, Tokyo Electron about 5%, memory maker Kioxia 4.2%. Micron’s report lit a fire across the semiconductor complex — everywhere except in Micron’s own shares.
That contradiction is the real story. It tells you where investors now think the value sits in the third year of the AI buildout: not with the company converting scarcity into record margins, but with everyone lining up to claim a share of that scarcity — equipment vendors, construction contractors and, in a twist that matters more than it sounds, Micron’s own workforce. The most important number in this report is not in the revenue line. It is in a footnote on margins.
The Numbers: A Memory Maker With Software Margins
Start with the full fiscal year, which ended in late August. Micron generated $133.19 billion in revenue in fiscal 2026, up from $37.38 billion the year before — an increase of roughly 256%. Adjusted net income came to $86.76 billion, or $75.52 per share. Operating cash flow hit $89.68 billion; after $27.37 billion in net capital spending, adjusted free cash flow was $62.31 billion. For a company that posted losses in some quarters only two years ago, this is not an upswing. It is a regime change.
In the fourth quarter alone, DRAM contributed $39.8 billion and NAND flash $14.1 billion, both records. On DRAM, bit shipments grew only in the mid-single digits sequentially, while prices rose in the high teens — in three months. NAND prices climbed roughly 30% quarter over quarter, according to management. That is the heart of it: Micron is not selling dramatically more memory than it did last quarter. It is selling it at a completely different price.
The segment split makes the point even more vividly. Core Data Center, the server-memory business outside the largest cloud accounts, posted $18.0 billion in revenue against $1.577 billion a year earlier — more than an elevenfold increase — at a 90% gross margin. Cloud Memory, home of the high-bandwidth memory (HBM) stacked next to AI accelerators, brought in $16.28 billion at 83%. Even Mobile and Client, which supplies smartphones and PCs, delivered $13.11 billion at 90%. When the consumer unit earns the same margin as the AI unit, it means a single product is not getting pricier. An entire resource is.
For context: a year ago, in the fourth quarter of fiscal 2025, Micron’s adjusted gross margin was around 46%. Within twelve months, the share of each revenue dollar left over after production costs has nearly doubled. No commodity chipmaker has ever printed margins like these. They belong to enterprise software companies — except Micron earns them with fabs, clean rooms and silicon wafers.
The Footnote: Bonuses Worth 35 to 68 Months of Pay
Now to the sentence that capped the stock. For the first quarter of fiscal 2027, Micron guided to an adjusted gross margin of 86.25%, down roughly three-quarters of a point from the record. The Street had expected another step up. CFO Mark Murphy was blunt about why: bonuses are a significant factor in the gross margin outlook. All told, Micron expects about $1 billion of extra cost pressure in the quarter from incentive compensation and startup expenses at new manufacturing capacity.
The detail behind that is extraordinary. Micron plans to pay employees in Taiwan, where a large share of its DRAM output is produced, bonuses equivalent to 35 to 68 months of their fiscal 2026 salary. The minimum payout, according to Korean press reports, is 1.7 million Taiwan dollars. Unions had asked for 83 months in September and floated a strike vote; going forward, they want 15% of operating profit distributed to staff every quarter.
This is not an HR footnote. It is the first visible spot where the scarcity rent Micron is collecting starts flowing out of the company. Engineers and technicians who can run advanced memory fabs in Taiwan, Korea or Japan have become a scarce resource themselves. When they see their employer earning an 87% gross margin, they want a cut. Reports out of Seoul suggest Samsung and SK Hynix face exactly the same pressure. For shareholders, the takeaway is subtle but important: margins may well rise again — Micron explicitly called the first quarter the low point for fiscal 2027 — but the path upward is no longer unobstructed. There are more people at the table now.
The Second Outflow: More Than $50 Billion for Concrete and Tools
The other reason for the muted reaction sits in the spending plan. Micron expects capital expenditures of about $11.5 billion in the first quarter and roughly $25 billion in the first half of fiscal 2027, with the second half running higher still. That puts the full year north of $50 billion — close to double fiscal 2026. Most of the increase, the company said, is construction spending aimed at bringing clean-room space online faster from late calendar 2028 onward.
The timeline is the crucial part. The new ID-1 fab in Idaho is slated to ramp in late 2028. Capacity in Singapore and Japan arrives between 2027 and 2028. The first New York fab is not expected until around 2030. In other words, Micron cannot meaningfully ease the shortage before the end of 2028 even if it wanted to. After that, though, new supply arrives — not just from Micron, but from Samsung, SK Hynix and China’s CXMT, which is expanding its own DRAM output.
That is the pattern every veteran semiconductor investor knows by heart. High prices produce high margins, high margins produce heavy capex, and heavy capex produces overcapacity and falling prices two or three years later. The market is not modeling the next quarter. It is modeling the quarter when the new clean rooms start shipping wafers — and Wednesday’s numbers made that date more concrete.
Why the Money Went to the Toolmakers
That explains the action in Tokyo. For Micron, every extra billion in capex is a cost and a future pricing risk. For Advantest, Tokyo Electron and their peers, the same billion is revenue. Advantest builds the test systems every HBM stack must pass through — and HBM is unusually test-intensive, because twelve or more memory dies are stacked on top of each other and one defect can scrap the entire package. Tokyo Electron earns on deposition and etch. Kioxia benefits directly from the NAND price spike.
From a portfolio manager’s perspective, it is a clean trade: the equipment supplier gets the volume of the investment wave without carrying the price risk of the memory cycle. As long as Micron, Samsung and SK Hynix are building, the toolmakers are selling. When the cycle turns, they get hit too — but typically with a lag, because projects already underway get finished. Thursday morning’s move was not a vote of no confidence in Micron. It was a bet that the next two years belong to the suppliers while memory pricing approaches its peak.
Seoul was more restrained. The Kospi reversed an early dip and traded around 6,931, up roughly 1.4% at one point; SK Hynix rose about 1.6% and Samsung Electronics around 1%. The Korean memory giants share Micron’s margin headaches — bonus demands, heavy capex, questions about how long the shortage lasts — plus currency risk. That they barely moved on a record quarter from their most direct rival reinforces the read.
The Bull Case: This Time There Are Contracts
Investors who still see Micron as undervalued have a strong argument, and it is also in this report. Micron has now signed 26 Strategic Customer Agreements, long-term supply contracts running as far out as 2031. Customer prepayments under those deals total $32 billion, up from $22 billion in June. Remaining performance obligations stand at roughly $150 billion. More than 75% of fiscal 2027 output is already committed, and the company says it has locked in the vast majority of its 2027 HBM supply at significantly higher prices than this year.
That is new for the memory industry. Historically, DRAM was sold almost entirely on short-term contracts and in the spot market; when prices fell, they fell immediately and for everyone. When hyperscalers wire $32 billion upfront to secure capacity through 2031, part of the risk shifts onto the customer. The cycle does not disappear, but it gets stretched out and smoothed.
Then there is valuation. At a Wednesday close of around $1,065, Micron carries a market value of about $1.2 trillion. Annualize the first-quarter guidance of $38.15 in adjusted EPS and you get a price-to-earnings ratio of roughly 7. On trailing fiscal 2026 earnings, it is about 14. For a company that expects memory markets to be even tighter in 2027 and 2028 than in 2026, that is cheap. But the low multiple is also the message: the market is pricing Micron like a commodity producer at the top of its cycle, not like a growth company.
How U.S. Investors Can Play It
For American investors, the memory trade now comes in three flavors. The first is the producers: Micron itself, and since July, SK Hynix through its Nasdaq-listed ADRs, which gives U.S. accounts direct access to the world’s largest HBM supplier without a Korean brokerage. Sandisk, the flash business spun out of Western Digital, offers a purer NAND bet and rides the same 30% price jump that lifted Micron’s storage revenue. These names carry the most upside if the shortage really lasts through 2028 — and the most downside if it does not.
The second flavor is the toolmakers: Applied Materials, Lam Research and KLA in the U.S., plus ASML for lithography. Lam in particular has deep exposure to memory, since etch and deposition steps dominate DRAM and 3D NAND manufacturing. More than $50 billion of Micron capex, plus whatever Samsung and SK Hynix announce in their own October reports, is a direct order book for this group. Teradyne competes with Advantest in memory and HBM testing, though with a smaller share.
The third flavor is the one most investors overlook: the customers absorbing these prices. Dell, HP and Apple all have to buy memory at today’s rates, and every percentage point of Micron’s gross margin is, in part, someone else’s margin squeeze. Investors long hardware names should be checking how much memory cost inflation is already baked into guidance — Apple’s recent iPhone price increase showed that passing it along is possible, but only partially.
The Risks Beyond the Cycle
Beyond the question of when new capacity floods the market, there are three concrete risks. First, rates: the 10-year Treasury yield tested levels just above 5.30% on Wednesday. A P/E of seven may look cheap, but with long bonds paying more than 5%, the bar for cyclical earnings is higher than it was in the era of cheap money. Second, the Netlist case before the U.S. International Trade Commission, which in a worst-case outcome could restrict imports of certain Micron AI memory products. Third, China: CXMT keeps expanding DRAM production and is likely to pressure prices first in the commodity segments where Micron is currently earning 90% margins too.
And behind all of it sits the bigger question: how long can customers keep paying? PC and smartphone makers have already cited memory costs to justify price increases. Hyperscalers are increasingly funding AI spending through bond issuance rather than operating cash flow alone. As long as AI demand absorbs everything, none of that is visible. The moment a major buyer trims its capex plan, investors will find out how much of that 87% margin is structural and how much is simply scarcity.
Bottom Line: The Record Is Priced In, the Split Is Not
On Wednesday, Micron reported what may be the best quarter in the history of the memory industry, and its guidance promises even more for the current quarter. There is nothing to argue with in the numbers themselves. The stock barely moved anyway, because the market is asking a different question than what next quarter looks like: who gets the scarcity rent once it starts being shared?
The answer emerging from this report is: increasingly, not only shareholders. The workforce is claiming its share in the form of double-digit months of salary. Contractors and toolmakers are collecting theirs through a capex wave of more than $50 billion. And customers are locking in prices through prepayments that may one day sit below the spot market. None of that is a reason for Micron shareholders to panic — the long-term contracts and the low multiple provide real cushion. But it is a sign that the easy part of the memory boom is over. On Thursday morning, the market did not trade that insight in Boise. It traded it in Tokyo.
