Micron Guides to $50 Billion and Record Margins, Repricing the Memory Trade

The Guide Did the Damage

Micron's fiscal third quarter was always set up to be loud, but the headline numbers weren't the surprise. Revenue came in at $41.5 billion, up 346% year over year and 74% sequentially, with non-GAAP EPS of $25.11 against a Street estimate near $20.60. A beat of that size was broadly priced in after the pre-earnings ramp. What actually moved the stock was the forward guide: Micron is steering fiscal Q4 to $50 billion (±$1 billion) in revenue and roughly $31 in non-GAAP EPS, against a consensus that sat around $43 billion. That isn't a beat — it's a step-change in what next quarter looks like, and a gross-margin guide near 86% says the mix gets richer, not thinner.

Memory Stopped Acting Like a Commodity

The number that reframes Micron is the margin. Q3 gross margin hit a record 84.9%, up from roughly 38% a year ago. Memory has historically been a brutal boom-bust business where pricing collapses the moment supply catches demand. A high-80s margin says the opposite is happening right now: HBM and leading-edge DRAM are scarce and priced like it. Micron backed that up with 16 customer agreements representing about $100 billion in minimum contracted revenue running through 2030 — on full execution, half or more of total revenue sits under contract. On the product side, the HBM4 12-high ramp is tracking twice as fast as HBM3E, with over $1 billion of HBM4 already shipped. Locked pricing plus sold-out leading-edge capacity is what a structural shortage looks like on a P&L, and it's why the margin guide doesn't roll over.

The Street Was Already Chasing

Analysts didn't wait for the print to reprice. The day before earnings, Bank of America lifted its target to $1,500 from $950 — a 58% raise — even as MU sold off about 10% intraday, citing a $2.7 trillion semiconductor addressable market by 2030. The setup was primed two days earlier by the Micron–Anthropic agreement, which pairs a multi-year HBM, DRAM and SSD supply deal with a Micron investment in Anthropic's Series H round. The print validated the front-running: shares jumped roughly 13% after hours toward $1,186, knocking on the 52-week high near $1,213, and a fresh wave of $1,500 targets followed. The risk worth naming is the obvious one — this is a deeply cyclical industry, and the same contracted demand that's tightening pricing today is funding the capacity that eventually loosens it.

Reading the Perp Premium

On Hyperliquid, the MU perp pushed to about $1,207, which sits *above* the roughly $1,186 after-hours spot print. That gap is extended-hours basis: the perp trades continuously while the underlying cash market is closed, so it tends to front-run and occasionally overshoot the next session's open. With about $641.5 million in 24-hour volume on this market, there's enough depth for the perp to do real price discovery overnight, but the premium to spot is the variable that matters — it can compress fast if the cash open prints below where the perp has run. It's also worth noting this is the third leg of the same post-earnings move, so a meaningful share of the 20% is continuation and basis rather than fresh information hitting the tape.
