Micron reported its fiscal fourth quarter and full year on 30 September, after the close. Revenue of $54.2 billion in a single quarter, GAAP net income of $37.7 billion, and a guide for this quarter of $61.5 billion. Here is the detail, and the part of it that decides what happens next.
THE QUARTER, ENDED 3 SEPTEMBER, IN GAAP TERMS
Revenue $54.229 billion, against $11.315 billion in the same quarter a year ago. Up 379% year on year and 31% from the previous quarter. GAAP net income $37.701 billion, against $3.201 billion. GAAP diluted EPS $32.87, against $2.83.
That is a net margin of 69.5%, against 28.3% a year ago. Of every dollar of revenue, almost seventy cents reached the bottom line after all costs, interest and tax. For the full year, revenue was $133.2 billion, up 256%, GAAP net income $85.0 billion, GAAP diluted EPS $74.33.
By product, DRAM was $39.8 billion, 73% of revenue, up 343% year on year. NAND was $14.1 billion, 26% of revenue, up 526%.
AGAINST ITS OWN GUIDANCE
Three months earlier the company had guided revenue to $50.0 billion plus or minus $1.0 billion and GAAP diluted EPS to $30.73 plus or minus $1.00. It reported $54.2 billion and $32.87, above the top of both ranges. Consensus sat at $50.45 billion of revenue, so the quarter came in 7.5% above what the market expected.
WHERE THE REVENUE CAME FROM
Core Data Center $18.0 billion, from $1.6 billion a year ago. Cloud Memory $16.3 billion, from $4.5 billion. Mobile and Client $13.1 billion, from $3.8 billion. Automotive and Embedded $6.8 billion, from $1.4 billion.
The two data center units together are now 63% of the company. A year ago they were 54% of a company one fifth the size. Data center SSD revenue on its own was close to $10 billion in the quarter, more than ten times the year ago figure, and server LPDDR module revenue more than doubled in a single quarter.
HBM revenue grew faster than the company as a whole. Management said calendar 2027 HBM prices are much higher than 2026 levels and that most of next year's HBM volume is already sold at those prices.
THE ORDER BOOK
This is the part that separates this cycle from previous ones. Micron now has 26 strategic customer agreements, 10 of them signed during this quarter alone. Remaining performance obligations, the revenue already contracted but not yet delivered, stand at about $150 billion. That is more than the company's entire fiscal 2026 revenue. Customers have also put $32 billion of financial commitments behind those agreements, and more than 75% of fiscal 2027 output is already committed.
A memory maker that sells into the spot market is worth one thing. A memory maker with four years of contracted volume is worth another. The agreements run through 2030.
THE CASH, AND WHERE IT IS GOING
The quarter produced $44.0 billion of operating cash flow, spent $10.8 billion on capital expenditure, and left $33.2 billion of free cash flow. For the full year, $89.7 billion of operating cash flow and $62.3 billion of free cash flow. Cash and investments ended at $73.5 billion against total debt of $5.2 billion, and inventories at $10.4 billion.
Now the turn. Capital expenditure for this quarter alone is guided at about $11.5 billion, and the first half at about $25 billion. All of fiscal 2026 cost $27.4 billion. The company is funding clean room space that produces wafers later: first output from the Idaho fab around the middle of calendar 2027, Singapore early in 2027, Taiwan mid 2027, a second Idaho fab and Japan in late 2028, New York in 2030. Cash earned in 2026 is being spent on capacity that sells in 2028 and beyond.
On capital returns, the board declared a quarterly dividend of $0.15 a share, the company repurchased $0.65 billion of stock during the year, and management said returns to shareholders will step up from 9 December.
THE GUIDE, AND THE CALENDAR
Revenue of $61.5 billion plus or minus $1.5 billion, GAAP diluted EPS of $37.84 plus or minus $1.00. Consensus had been $56.8 billion, so the guide is about 8% above it.
One detail the headline number hides. The quarter just reported contained 14 weeks, because fiscal 2026 was a 53 week year. The quarter being guided contains 13. On the headline, revenue is guided up 13%. Per week of sales, it is up 22%.
THE REACTION
The stock closed at $1,065.11 on the day of the release and traded flat immediately after the numbers came out. The next day it closed at $1,097.39, up 3.0%. On Friday it gave back 2.1% to $1,074.89. Two sessions after a 7.5% revenue beat and a guide 8% above consensus, the share price sits about 1% above where it started.
WHAT THIS IS
A year ago this was an $11.3 billion quarter at a 28% net margin, in an industry whose defining feature was that nobody could forecast the next six months. It is now a $54.2 billion quarter at 69.5%, with three quarters of next year's output already committed, a $150 billion contract book, and capital spending accelerating into capacity that arrives in 2028.
The cycle has not been repealed. It has been sold forward.
So which number would you underwrite: the 69.5% net margin, or the $150 billion of contracts behind it?
