Micron reported fiscal fourth-quarter 2026 results on September 30, 2026, and the headline is hard to miss: revenue of $54.23 billion, up from $11.32 billion a year earlier. This follows the numbers we flagged in our Micron earnings preview.

What were Micron's fiscal Q4 2026 numbers?

Per Micron's earnings release filed with the SEC, Q4 GAAP gross margin was 86.8%, or $47.05 billion. Operating cash flow was $43.97 billion for the quarter, against $5.73 billion a year ago. For the full fiscal year, GAAP gross margin was 80.7%, operating cash flow was $89.68 billion and net capital spending was $27.37 billion.

Where did the revenue come from?

Micron reports by customer segment in this release, not by DRAM and NAND:

• Cloud Memory: $16.28 billion at an 83% gross margin
• Core Data Center: $18.00 billion at a 90% gross margin
• Mobile and Client: $13.11 billion at a 90% gross margin
• Automotive and Embedded: $6.82 billion at an 84% gross margin

Data center segments together contributed more than $34 billion, which shows how heavily AI infrastructure is driving memory demand.

What is Micron's guidance for next quarter?

For Q1 fiscal 2027, Micron expects revenue of $61.5 billion plus or minus $1.5 billion, a GAAP gross margin of about 85.95% and non-GAAP diluted EPS of $38.15 plus or minus $1.00. Investing.com's summary of the slides also describes supply as much tighter through 2027 and 2028, a reading we attribute to that outlet.

Why should readers care?

Memory is the quiet constraint behind AI servers, and Micron's numbers are a useful read on that demand. Treat guidance as a company forecast, not a promise, and this is not investment advice. More market coverage is in our stock trading section.
