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 (52 days away). Micron Technology Inc beat estimates in all 4 of the last 4 quarters (average surprise +13.7%); a miss would break that pattern.
• An open-market purchase by an insider at Micron Technology Inc. There has been none in 90 days; Form 4 filings would show one within two business days of the trade.
• Analyst ratings: the average score moved from 4.24 to 4.21 over three months (on a scale where 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, 38.2% above the latest close of $877.55; a close below $201.13 would be a new 52-week low, 77.1% below it.
• Growth: revenue rose 256.3% year over year in the quarter ending Sep 2026 (trend: accelerating). At a P/E of 11.8, 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.

How MU compares with its peers

Over the past month MU ranks 1 of 3 in this group (-18.8%); the best was MU (-18.8%) and the weakest SNDK (-29.4%).

MU's P/E of 11.8 is below the peers' median of 15.1, so investors pay less for each dollar of its profit.

MU history: what happened after similar moves

Since 2023, MU fell 18.8% or more in a month 5 times (separate episodes, not counting the current one). Three months later it was higher in 4 of 5 cases; the median change was +24.5%.

Past moves don't predict the next one; they show how volatile the stock has been.

Key terms on this page

P/E ratio

Price divided by the last 12 months of earnings per share. A P/E of 20 means investors pay $20 for each $1 of yearly profit. It is only defined when the company is profitable.

Price-to-sales

Market value divided by the last 12 months of revenue. Useful for companies with little or no profit, but it ignores margins.

Form 4

The SEC form a company's officers, directors and 10% owners must file within two business days of buying or selling its stock.

Open-market trade

A purchase or sale on the exchange at the market price, paid with the insider's own money (code P or S on Form 4), as opposed to option exercises, grants or gifts.

Form 13F

A quarterly SEC report listing the U.S. stock holdings of every investment manager with more than $100 million. It is due 45 days after each quarter ends, so it shows positions with a delay.

Dilution

When a company issues new shares, each existing share owns a smaller piece of the company. Common sources: stock offerings, convertible debt and large stock-based pay.

Form 8-K

The SEC form for material events between quarterly reports: earnings releases, deals, executive changes, stock offerings and similar news.
