In Micron Technology Inc's own words

“Micron delivered record fiscal 2026 results, and we expect an even stronger fiscal 2027”

— Sanjay Mehrotra, Chairman and CEO of Micron Technology · SEC filing

From the company's earnings release filed with the SEC on 2026-09-30 (Form 8-K).

What would change the picture for MU

These are the specific events and levels to watch. None of them is a prediction.

• The Dec. 15, 2026 earnings report is 47 days away. Micron Technology Inc beat estimates in all 4 of the last 4 quarters, with an average surprise of +16.2%. A miss would break that pattern.
• An open-market purchase by an insider at Micron Technology Inc would show up on Form 4 filings within two business days of the trade. There has been none in 90 days.
• Analyst ratings: the average score moved from 4.24 to 4.21 over three months. On this scale, 5 is strong buy and 1 is strong sell. A run of downgrades after earnings usually shows up here first.
• Price levels: a close above $1213.18 would be a new 52-week high, 23.4% above the latest close of $983.23. A close below $201.13 would be a new 52-week low, 79.5% below it.
• Growth: revenue rose 256.3% year over year in the quarter ending Sep 2026, and the trend is accelerating. At a P/E of 13.2, a slowdown would matter more than at a lower multiple.
• New shares: dilution risk is low now. A new shelf registration (S-3) or a prospectus supplement (424B) for an offering would raise it.
