Micron's Guidance Will Be the Whole Memory Market's Answer

Micron Technology reports fiscal fourth-quarter results on Wednesday after the close, and the numbers on the page are going to look surreal.

The Zacks Consensus Estimate calls for revenue of $51.0 billion, an increase of roughly 350% from the $11.3 billion posted a year ago, with adjusted earnings near $31.61 per share against $3.03 in the prior-year quarter. For the full fiscal year, consensus sits around $129.8 billion in revenue and $74.02 per share — growth of 247% and 793% respectively. Companies of this size do not ordinarily post numbers like these.

And almost none of it will determine how the stock trades Thursday morning.

The Quarter Is Already Known

Micron guided fiscal fourth-quarter revenue to $50.0 billion plus or minus $1.0 billion, adjusted earnings of $31.00 plus or minus $1.00, and an adjusted gross margin near 86%. Consensus has since converged above the midpoint of that guide on every line, which tells you the Street expects a beat and has already priced one in.

The company has cleared the Zacks Consensus Estimate in each of the trailing four quarters, averaging a surprise of 21.06%. The Earnings ESP currently stands at +0.23%, with the Most Accurate Estimate of $31.68 sitting modestly above the $31.61 consensus. A beat looks probable. It also looks expected, which is a different thing entirely.

What matters is the November-quarter guide and, above all, the gross margin outlook. At 86%, Micron is earning a margin that would be extraordinary for a software company, let alone a capital-intensive manufacturer that spent the better part of two decades in brutal commodity cycles. The question the market needs answered is whether that is a peak or a plateau.

HBM Is the Franchise Now

The transformation underneath these numbers is striking. Micron (MU - Free Report) is no longer a commodity DRAM producer that happens to sell some high-bandwidth memory. HBM has become the engine, and management is targeting HBM market share roughly in line with its overall DRAM share — an ambitious goal given the company’s historical position as the smaller of the three major players.

HBM4 12-high is reportedly ramping about twice as fast as HBM3E 12-high did, and DRAM revenue for the quarter is modeled near $38.26 billion, up roughly 326%. HBM largely sells under fixed-price, long-dated agreements rather than spot pricing. That has been enormously stabilizing on the way up — it is why Micron can guide to 86% margins with confidence. On the other hand, fixed contracts cut both ways, and they will cap the upside if spot pricing keeps climbing.

Why the Rest of the Market Should Care

Micron’s guidance is the single best read available on memory pricing, and memory pricing has quietly become one of the most consequential variables in technology.

Consider what has already shown up downstream. Nvidia guided gross margin toward 71% to 72% by its fourth quarter, with CFO Colette Kress attributing the pressure to memory scarcity “being driven in large part by the AI buildout itself.” Microsoft disclosed roughly $5 billion of higher component pricing in a single quarter. Dell’s inventories more than doubled to $21.3 billion, a build that looks very much like pre-buying ahead of further increases — and which helped push its free cash flow down 47% even as net income rose 255%.

Every one of those outcomes traces back to what Micron and its two competitors decide to charge. If Wednesday’s guide points to continued tightness into 2027, the cost pressure on server makers, hyperscalers and accelerator vendors persists, and the memory names keep taking an outsized share of AI infrastructure profits. If Micron signals that supply is catching up, that dynamic reverses — good news for the buyers, considerably less so for the sellers.

The read-through extends to NAND as well. SanDisk (SNDK - Free Report) has been among the strongest performers in the entire market this year on a structural NAND shortage, and while Micron’s DRAM and HBM commentary doesn’t govern NAND directly, the two markets share fabs, capital budgets and customer psychology. Any hint that capacity discipline is loosening would be felt across the complex.

Bottom Line

Micron’s stock is up close to 275% this year and not far from the $1,255 record. Analyst price targets now span a remarkable range, from roughly $1,100 to $2,000, which is itself a statement about how little agreement exists on what this business earns on the other side of the cycle.

Wednesday is not about whether Micron beats. It almost certainly will. It is about whether the 86% gross margin is a waypoint or a high-water mark, and whether management can describe fiscal 2027 in terms that justify a stock which has nearly quadrupled.
