Micron Stock in Focus After Q4 Earnings Beat and Strong Revenue Forecast
Micron reported fourth-quarter results above Wall Street estimates and guided higher, putting MU shares in the spotlight after a huge run driven by AI memory demand.

Micron Technology (NASDAQ: MU) is trending after the memory chipmaker reported fiscal fourth-quarter results on Wednesday that beat Wall Street expectations on both revenue and earnings. It also gave a forecast for the next quarter that came in above analyst estimates.
The report landed after the market closed, so investors are now weighing how the stock will respond after a run that has made it one of the market's standout performers.
What Micron reported
According to Yahoo Finance, Micron posted earnings per share of $33.42 on revenue of $54.23 billion. Analysts surveyed by Bloomberg had expected EPS of $31.83 and revenue of $51.49 billion.
The year-earlier quarter looks tiny by comparison: EPS of $3.03 on revenue of $11.31 billion.
For its guidance, Micron projected revenue of $60 billion to $63 billion. Analysts had been looking for about $56.77 billion. Yahoo's article refers to this as a second-quarter figure in its text but calls it a "Q1 outlook" in its headline, so the exact fiscal period is worth confirming in Micron's own release.
Why the stock has surged
Micron is one of the world's three big memory makers, alongside Samsung and SK Hynix. Demand for their chips has jumped as companies build out AI data centers.
Those facilities need huge amounts of DRAM, including the high-bandwidth memory used alongside AI processors, as well as fast flash storage. Micron makes both.
Yahoo Finance reported that Micron shares were up roughly 275% year to date and about 550% over the past 12 months as of Wednesday. A separate Motley Fool analysis, published on The Globe and Mail, put the gain at nearly 600% over the past year through the last week of September, with a share price around $1,080.
The other side of the boom
Higher memory prices are being felt elsewhere in tech. Yahoo reports that consumer electronics makers have raised device prices to offset rising memory and storage costs. Apple's iPhone 18 Pro line, for example, is $100 more than the iPhone 17 Pro.
Those higher prices have reduced the number of devices sold, Yahoo says, but they have offset much of the hit to manufacturers' bottom lines.
Memory and chip stocks have also been volatile in recent weeks. Yahoo links that to concerns about AI safety after Anthropic CEO Dario Amodei called earlier this month for slower development of frontier AI models.
What to watch
Micron is also investing for the long term. In August it said it would spend up to $10 billion over the next 10 years on a research institution in Boise, Idaho.
The Motley Fool writer cautions that memory has historically swung between booms and busts. The writer notes that Micron gets about 75% of its revenue from DRAM and 25% from NAND, and that it has less exposure to high-bandwidth memory than SK Hynix. That would leave it more vulnerable if conventional memory prices fall. The same piece says analysts do not expect a bust as severe as past ones.
