Micron Technology shares ripped higher after Morgan Stanley sharply lifted estimates and its price target, arguing that a structural shortage across DRAM—especially high-bandwidth memory (HBM)—is extending into 2026 and beyond. Underneath the headline, the thesis is simple: AI servers are eating all available bits, pricing is resetting higher, and Micron’s product mix is tilting toward its most profitable lanes. The debate now is less about whether the upcycle is real and more about how long tight supply can hold before industry capacity catches up.
What changed
Morgan Stanley’s semiconductor team, led by Joseph Moore, took its MU price target to $450 from $350 and kept an Overweight stance. The driver: a faster-and-tighter memory market than they had modeled, with fresh evidence that HBM and DDR5 pricing are firming into mid-2026. The note also points to the potential for $50+ in FY26 EPS under bullish pricing and mix—numbers that would have sounded fanciful a year ago but are increasingly anchored by booked supply and rising average selling prices (ASPs).
On the company side, CFO Mark Murphy used a conference appearance to directly address investor anxieties about competitive positioning in next-gen HBM. He said Micron’s HBM4 is already in volume production and shipping, and he reiterated that 2026 HBM supply is effectively sold out—with demand running well ahead of what the industry can physically deliver. That clarification helped knock down chatter that rivals had seized a decisive lead in the HBM4 node.
Why the setup is powerful
1) Tight supply + richer mix = operating leverage.
DRAM/NAND are classic commodity markets—until they aren’t. In AI, memory is becoming a performance gate, pushing buyers to pay for guaranteed HBM density, bandwidth, and power envelopes. As HBM climbs from single-digit to double-digit share of Micron’s DRAM revenue, blended gross margins should expand even before broader DRAM pricing fully normalizes. The Street is keying on that mix tailwind as much as on headline ASPs.
2) Multi-supplier is a feature, not a bug.
AI accelerator vendors—above all Nvidia—prefer dual or triple sources once yields stabilize. That dynamic caps any one supplier’s share but stabilizes utilization and pricing across the cohort. Even if rivals like SK hynix and Samsung Electronics lead initial ramps at specific customers, large buyers tend to spread orders as they scale. Morgan Stanley’s call leans into that industry reality rather than assuming a single-winner HBM world.
3) Visibility beats cyclicality—for now.
Micron and peers have pre-sold most premium bits through 2026. That doesn’t eliminate cycle risk, but it raises the floor under near-term numbers and allows fabs to run more predictably. With supply additions gated by long equipment lead times, clean-room expansions, and power constraints, the market can stay snug even as shipments grow.
What the numbers could look like
Take a simplified bridge to FY26: if DRAM ASPs continue to stair-step and HBM mix inches higher each quarter, Street models can migrate toward peak-like EPS scenarios without heroic assumptions on PC/handset demand. Morgan Stanley’s more bullish path sketches $52 EPS potential, which implies mid-to-high 20s operating margins at scale—levels consistent with prior memory peaks but built on a very different mix (HBM/DDR5 vs. commodity PC DRAM). Whether that power sustains hinges on how fast capacity expands and how sticky AI training/inference demand proves through 2027.
The near-term catalysts
- HBM4 production cadence. Micron has publicly said HBM4 is in high-volume production and shipping; any third-party validation (design wins, teardown data) will be watched for yield and performance proof points.
- Pricing prints. Spot trackers and OEM commentary on DDR5/LPDDR5X should continue to show sequential price increases into 2H26, reinforcing the “shortage” narrative.
- Customer color. Read-throughs from Nvidia and large cloud buyers on memory content per accelerator/server will drive top-down demand math for bits/box into 2027.
What could go wrong for Micron
Supply snapback. Memory cycles die when supply outruns demand. If competitors accelerate HBM/DRAM adds—or if yields rise faster than expected—pricing power can roll over in a few quarters. Watch capex and tool shipments carefully.
Node execution. Any stumble at the leading HBM node (thermal, stacking, or packaging issues) would force a reset to volume and mix assumptions, particularly if customers prioritize rivals while fixes land.
Customer concentration. AI memory demand is highly levered to a handful of accelerator programs. A delay in a flagship GPU or a pivot in memory architecture could ripple through orders and utilization.
Macro and policy. Export controls, power constraints at data-center campuses, or a cyclical pause in data-center capex would all dent the “sold-out” story more quickly than PC/phone demand would bail it out.
How to think about valuation
At today’s price, MU is discounting a multi-year period of above-midcycle profitability. If you underwrite FY26 EPS near $50 and slap a mid-teens multiple on “AI-quality” earnings, you can justify targets north of $450. If you believe memory mean-reverts quickly, a high-single-digit multiple on midcycle EPS lands far lower. The Street is migrating toward the former because visibility is atypically high and mix is atypically rich. The multiple you pay is really a judgment on how long “HBM-constrained” remains the baseline.
Bottom line
Micron enters 2026 with the wind at its back: sold-out HBM, firming DDR5, and a customer base racing to deploy AI capacity. Morgan Stanley’s upgrade crystallizes what the tape has been hinting at for months—the memory upcycle is no longer theoretical; it’s on the P&L. From here, the key tells are HBM execution, pricing durability, and competitor capex. If those break Micron’s way, “midcycle” could look a lot like prior peaks—only longer.
FAQ on Micron
Why did Micron pop today?
A bullish Morgan Stanley note raised the target to $450 and lifted estimates on continued DRAM/HBM shortages, while management reaffirmed strong HBM4 progress and bookings.
Is Micron really shipping HBM4 already?
Yes—management told investors HBM4 is in volume production and shipping; HBM supply for 2026 is effectively sold out.
What about competition from SK hynix and Samsung?
Both are formidable and are ramping HBM4, but large buyers generally multi-source over time, which supports pricing and utilization for all qualified suppliers.
How high can EPS go?
In a tight-supply scenario with richer HBM mix, bullish paths land near $50+ in FY26 EPS; that’s sensitive to pricing and yields.
What would change the story?
A rapid supply response (new capacity + better yields), an AI spending pause, or node-specific execution issues could compress pricing and reset expectations.
