Micron beat its revenue and gross margin guides, but price gains fade and the bill for a longer shortage rises

Revenue and margin beat the guide, but price rises fade

Micron's September 2026 quarter was another beat. Revenue came in at $54.2 billion, ahead of the range the company set in June, and the operating margin on the standard accounting basis (GAAP) was 80.7%. The quarter before it was 80.4%, so the margin has nearly stopped rising. That means most of every dollar of memory sold was left after the costs of making and selling it. A year earlier the figure was 32.3%.

Two things temper that. The quarter had an extra week, so growth on the quarter before flatters the business; by our arithmetic, per week, revenue rose 21.5%. More important, the engine of the past two quarters, rising prices, is slowing. The company said DRAM price increases fell from the low 60s percent to the high teens last quarter. By our reading, the pace of increase has shrunk sharply.

Management's case: longer shortage, contracts and deposits

Management did not point to another price surge; it said price increases continue at a more moderate pace, and made its case on the shortage lasting. The company said it has no line of sight to when supply and demand balance, and now describes the industry as supply constrained through 2028.

What it holds instead of a price surge is paper. It has signed 26 multi-year customer supply agreements, up from 16 in June, with about $150 billion of remaining obligations at minimum volumes and prices. Customers also paid in $12.3 billion of cash last quarter, more than the company had said to expect. That cash is a liability to be returned over time, not profit.

On how the prices are set, the company's chief operating officer said: "The majority of the pricing frameworks have floor and ceiling bands, but the newer ones are negotiated with an eye towards the current market conditions". Read plainly, the largest agreements signed by June carry ceilings set at the then-current price, so they may cap what Micron earns if prices keep rising; that is our reading. An analyst asked whether the ceilings and floors would all reset higher; the answer described several different frameworks.

Much of the extra spend is clean rooms due in late 2028

A longer shortage is expensive to serve. The capital spending guide for the year just ended started at $18 billion and was raised at each later call through June 2026; the actual was $27.4 billion. For the new year the company guided about $25 billion for the first half and more for the second. By our arithmetic that implies at least about $50 billion for the year; that is our sum, not a company guide.

The chief financial officer said most of the increase is for construction, agreeing that "the spend there doesn't translate into bits". Operating costs have also outrun the guide: last quarter's came in well above what the company said in June, and the rise it now guides for next year is far larger than the one it guided then.

What would have to be true, and what we do not yet know

For the plan to work, prices must hold near today's level while their increases fade, customers must honour their minimums, and the industry's own new clean rooms must not open into a surplus. The previous cycle, in the filed quarterly results, shows how fast the reverse can come: the operating margin went from clearly positive to deeply negative within a few quarters.

The cash cushion is real but smaller than it looks. Cash, marketable investments and restricted cash were $73.5 billion, and $12.9 billion sits in noncurrent customer contract liabilities, the filed line that holds customer deposits. The company intends to raise returns to owners from December, and ties that date to its CHIPS agreements. What it returned in dividends and share repurchases under its programme in the year just ended was a small share of adjusted free cash flow (the company's own measure), by our arithmetic.

What we learn next, and what the record shows

We will learn most next quarter: whether revenue reaches the level guided on only single-digit growth in bits shipped, which would point to prices still rising, our reading.

In the June guides for the quarter just ended, and in the capital spending guide through the year, Micron's own figures kept coming in higher than it said: revenue and margin above, capex and operating costs above. The earnings arrive a quarter at a time. The buildings, once poured, are there either way.
