Micron sees tighter memory supply in 2027 and 2028

Micron Technology reported record results on September 30, 2026, then warned that memory chips will get harder to buy, not easier. Its fiscal fourth-quarter revenue reached $54.23 billion. Chief executive Sanjay Mehrotra said the company "cannot currently see when supply and demand will return to balance," according to Yahoo Finance.

That matters to anyone who buys servers, PCs or phones. Micron makes the memory chips inside all three, and it says supply will be much tighter in 2027 and 2028 than it was in 2026.

The quarter in numbers

Micron's results release gives these figures:

Measure	Fiscal Q4 2026	Fiscal Q1 2027 guidance
Revenue	$54.23 billion	$61.5 billion, plus or minus $1.5 billion
GAAP gross margin	86.8%	About 85.95%
GAAP earnings per share	$32.87	$37.84, plus or minus $1.00
Non-GAAP earnings per share	$33.42	$38.15, plus or minus $1.00

Full-year fiscal 2026 revenue came to $133.19 billion, Micron says. The company held its earnings call on Wednesday, September 30, at 2:30 p.m. Mountain Time.

The quarter beat expectations, though the sources cite slightly different forecasts. Yahoo Finance puts the analyst consensus at $50.97 billion in revenue and $31.35 in earnings per share, while Aroged cites $51.07 billion and $31.61. Analysts had expected about $57 billion in revenue for the next quarter, so Micron's $61.5 billion guidance is well ahead. Yahoo Finance calls it Micron's eighth straight quarter of beating estimates.

Why supply stays tight

Most of next year's output is already spoken for. Yahoo Finance reports that more than 75% of Micron's 2027 output is committed to customers. Aroged goes further and reports that all of 2027's production is sold out, so the two sources differ on the exact share.

High-bandwidth memory is the tightest product. Known as HBM, it is the stacked memory that sits beside AI chips in data-center accelerators. Yahoo Finance says Micron's HBM is largely sold out, at much higher prices than in 2026.

Micron has also locked in long contracts. PANews reports 26 long-term agreements worth about $150 billion in committed customer orders.

New factories will not help soon. Fresh capacity from new plants does not arrive until late 2028, Yahoo Finance reports. Micron plans to spend about $25 billion on equipment and plants in the first half of fiscal 2027, and more in the second half, according to PANews.

Aroged quotes Mehrotra this way: "In 2027 and 2028, we expect demand to exceed supply." He added that he expects shortages "to be more severe than in 2026."

Where the growth is coming from

AI data centers are driving the demand. DRAM, the working memory in servers and PCs, made up 73% of Micron's revenue and grew about 3.5 times year over year, Aroged reports. The same report says server SSD sales grew by more than 1,000% and are approaching $10 billion.

Mehrotra framed it in the results release: "AI is becoming Super Intelligence, and memory enhances this intelligence."

The pressure is already showing up in prices. In September, DRAM and NAND contract prices rose again as memory makers moved capacity to AI servers. Phone buyers have felt it too: smartphone prices in India are up 21% this year.

What this means for developers

Buy memory-heavy hardware early. If your team plans to add servers, GPU nodes or high-memory workstations in 2027, Micron's outlook says waiting will not make them cheaper. Get quotes now and lock in prices where suppliers allow it.

Budget for higher prices in 2027. Aroged reports that Micron expects memory prices to rise significantly next year, and the company cannot see when the shortage ends. Put a memory price increase into next year's hardware and cloud budgets instead of assuming this year's rates.

Use less memory where you can. Smaller AI models, 4-bit or 8-bit weights, tighter caches and right-sized cloud instances all cut how much memory you need. Each gigabyte saved is now worth more than it was a year ago.

Watch cloud pricing for memory-heavy instances. Cloud providers buy the same chips. If your bill depends on high-memory or GPU instances, review pricing updates and reserve capacity where it saves money.

Plan around late 2028. That is when Micron says new factory output arrives. Until then, treat memory as a constrained resource in hardware and capacity plans.
