Micron’s blowout earnings revived an old Wall Street worry

Micron $MU just delivered the kind of earnings report that usually earns a victory lap, a confetti cannon, and a few chest-thumping price-target hikes before breakfast. The company posted FY26 Q2 revenue of $23.86 billion, non-GAAP earnings of $12.20 per share, and a 74.9% non-GAAP gross margin, then guided the current quarter to about $33.5 billion in revenue, around $19.15 a share in non-GAAP earnings, and an 81% gross margin. 

And... the stock still slid about 5% in extended trading, with the weakness carrying into Thursday morning, when it was down 6.5%.

Investors had been waiting to see whether a company whose shares had surged nearly 65% this year — and more than quadrupled over the past 12 months — could clear a bar that had already been raised to an unhealthy altitude. Even before the report, options markets were implying roughly a 7% move by week’s end, and the stock had already blasted past the average analyst target. The company was trying to beat expectations that had already gone full Silicon Valley hallucination.

Micron’s report lives in the tension between two stories. One says AI has turned memory into one of the most important tollbooths in tech. The other says memory stocks still come with a long criminal record, and investors have seen enough booms to know that gigantic quarters can age poorly.

The quarter was cartoonishly strong

Micron set records across revenue, gross margin, earnings per share, and free cash flow. Revenue nearly tripled from a year earlier, while management said the quarter benefited from strong demand, tight industry supply, and broad execution across the business. The Q3 guide was even louder, with the company guiding to about $33.5 billion, far above the roughly $24.3 billion analysts were expecting. The quarter put a dollar figure on something the market has been sensing for months: AI demand is now strong enough to reshape the economics of memory.

AI has turned memory into a tollbooth

Micron has wandered out of the old commodity-chip script and into the AI bottleneck business — at least for now.

The company said AI will drive data-center DRAM and NAND bit TAM above 50% of industry TAM for the first time in calendar 2026, while both AI and traditional server demand are running into supply constraints. Micron has already begun volume shipments of HBM4 designed for Nvidia $NVDA’s Vera Rubin platform, and its data-center NAND revenue more than doubled sequentially in fiscal Q2; Micron says NAND demand is running materially above available supply for the foreseeable future. AI is pulling on the whole storage-and-memory stack. 

The market heard one number louder than the rest: capex

The cleanest explanation for the stock slip sits in capital spending. Micron now expects fiscal 2026 capex above $25 billion — a more-than-$5-billion raise — with roughly $7 billion in capex projected for the third quarter, and the company says fiscal 2027 spending will step up meaningfully again. 

Much of the increase is tied to clean-room and construction spending in Taiwan and at Micron’s U.S. fabs, with construction-related capex set to jump by more than $10 billion year over year in fiscal 2027. Investors heard the guide, then heard the invoice. 

Micron is pitching a richer, steadier story

Management is trying to teach the market a new way to think about memory. They’re trying to show that this is a structural shift, not just another sugar high. Micron said it has signed its first five-year strategic customer agreement, part of a push toward multiyear commitments that give customers more visibility and give Micron a sturdier business model. Micron may be pitching a structural AI-era shift, but the market is still treating memory like memory — a business with a long rap sheet and terrible impulse control.

The sell-side pounced on that angle. Barclays moved to a $675 target after the report; KeyBanc lifted to $600; TD Cowen moved to $550, while Stifel reiterated $550; Raymond James $RJF raised its target to $530; Morgan Stanley $MS raised to $520; and BofA went to $500, while Baird reiterated that price. Goldman was the notable wet blanket in the group, sticking with Neutral and a $400 target. 

The bullish case here rests on a simple hope: If AI keeps memory scarce and contracts get longer, the old boom-bust multiple starts to look too stingy.

Wall Street still remembers what memory stocks do

The market’s skepticism still makes sense, even with all the outrageously good numbers.

Memory investors have seen this movie before — tight supply, glorious pricing, heroic margins, then a rush to build capacity and a painful reminder that semiconductors can overdo a good thing faster than almost any industry alive. (Then, add a shaky broader tape, with oil spiking and major indexes under pressure.) And once a company starts posting numbers like these, investors stop asking whether the quarter was good and start asking whether it was the best it will ever get.

The quarter proved that AI demand is still industrial strength — that memory demand is red-hot (and part of the AI bottleneck). The selloff proved investors still think the bill could get ugly, the cycle could still turn, and the easy money in the story may already have been made.
