What Happened?

Micron Technology (MU) has been caught between two stories this week. Samsung’s threatened 18-day labor strike sent MU to an all-time high of $818.67 on May 11, then the stock whipsawed when Samsung averted the walkout at the last minute. Shares settled around $762. But the Samsung drama has buried a more durable signal: what Manish Bhatia, Micron’s Executive Vice President of Global Operations, disclosed at JPMorgan’s 54th Annual Global Technology, Media and Communications Conference on May 20.

The operational details from that session go well beyond what a stock chart can show.

HBM4 Is Running at Twice the Ramp Rate of Its Predecessor

High-bandwidth memory (HBM) is the stacked, specialized DRAM (dynamic random-access memory) that sits directly alongside AI accelerator chips in data centers, delivering data at extreme speeds. It has been the single biggest driver of Micron’s financial transformation over the past year.

The most important disclosure at JPMorgan: Micron’s HBM4, built on its 1-beta process node, is ramping “twice as fast as HBM3E 12-high did last year,” according to Bhatia. Yields are also improving faster than on HBM3E. Shipments into NVIDIA’s Vera Rubin GPU platform began in March 2026.

That execution shows up in the financials. Micron’s fiscal Q2 2026 results, reported March 18, showed revenue of $23.86 billion, up 196% year-over-year. DRAM revenue of $18.8 billion made up 79% of that total. CEO Sanjay Mehrotra guided for “significant records again in fiscal Q3,” with gross margins of approximately 81% for the May quarter.

Why Supply Cannot Keep Up With Demand

Bhatia’s core point at JPMorgan: the supply gap is structural, not cyclical.

Each new DRAM and NAND technology node delivers less bit growth per wafer than older nodes did. HBM makes this worse through what Bhatia called a “trade ratio”: because HBM die sizes are larger, each wafer produces far fewer bits than standard DRAM would. That ratio grows with every HBM generation, so more wafers are consumed per unit of output as the industry moves forward. Greenfield fab construction compounds the problem because it requires full production lines rather than incremental equipment upgrades.

Bhatia’s conclusion: “We don’t see the ability for supply to catch up to demand for the foreseeable future,” with tightness extending “well beyond calendar year 2026.” Key customers are still receiving only 50% to two-thirds of their memory requirements in the medium term.

On the demand side, Bhatia described a shift toward agentic AI workloads, where systems operate autonomously and interact machine-to-machine. These workloads are more inference-intensive and consume more DRAM per cycle than training workloads do. Context windows (the amount of information a model holds in active memory) are growing at around 30 times per year, per Bhatia, which drives additional NAND storage demand. AI architectures are evolving in ways that require more of every memory type Micron makes, not just more of one.

Three Disclosures the Market Has Not Fully Processed

Strategic Customer Agreements. Micron secured its first SCA (strategic customer agreement, a multiyear supply deal with locked-in volume and pricing) in a five-year deal with a large customer before the March earnings call. Bhatia confirmed “meaningful progress” with additional customers at JPMorgan. SCAs give Micron visibility to match years of greenfield fab investment against committed demand, which changes how earnings predictability gets valued.

Greenfield Expansion. Bhatia updated five simultaneous build-outs: the Taiwan Tongluo site (acquired from Powerchip Semiconductor, production targeted second half of calendar 2027, with a twin fab beginning construction this summer); Idaho 1 (pulled forward to mid-2027); Idaho 2 (groundwork underway, wafers targeted late 2028); New York (ahead of schedule, concrete pour expected later in 2026); and Singapore (HBM facility targeting 2027 production impact, plus a new NAND fab also underway).

ASML EUV Supply Deal. Micron recently concluded a multiyear supply agreement with ASML for EUV (extreme ultraviolet lithography) tools. ASML is the only commercial manufacturer of EUV tools. Bhatia confirmed 1-gamma, Micron’s current leading DRAM node, is performing ahead of expectations on yield since EUV was first deployed there. The agreement covers future generations, including 1-delta. Competitors without a secured EUV supply cannot match Micron’s process economics at leading-edge DRAM.

Micron Technology NTM EV/EBITDA (TIKR)

What the Valuation Actually Shows

At $762.10, MU trades about 24% above the Street’s mean target of $613. The analyst breakdown per TIKR’s Street Targets page as of May 21: 30 Buy, 9 Outperform, 4 Hold, 1 No Opinion, 1 Underperform, 1 Sell across 46 analysts. Even the most aggressive recent upgrades, including Melius Research and HSBC, each raising to $1,100 on May 18, and Mizuho raising to $800 on May 19, reflect conviction about demand durability rather than a signal that the stock is cheap at current levels.

On forward multiples, Micron looks inexpensive relative to peers. At 6.23x NTM EV/EBITDA, it sits well below the semiconductor peer group median of 15.51x. SK Hynix, the closest HBM competitor, trades at 4.11x NTM EV/EBITDA. On NTM P/E, Micron trades at 8.19x versus a peer group median of 27.42x. All multiples are from TIKR’s Competitors page as of May 21, 2026. The memory complex broadly trades at a discount because investors are pricing in eventual cycle normalization. That discount is either an opportunity or a warning, depending on how long the structural supply gap Bhatia described actually persists.

The TIKR mid-case model applies a revenue CAGR of around 11% from fiscal 2025 through August 2030, producing a target price of approximately $556, a negative total return of around 27%, and an annualized IRR of approximately (7%) per year. Put plainly: the current price already assumes the upcycle extends deep into the decade. The model says the market is pricing in more than the fundamentals currently support.

The two revenue drivers are HBM capacity expansion and data center SSD share gains. The JPMorgan conference transcript confirmed Micron grew its global enterprise SSD market share from around 5-7% in 2022 to approximately 15% by the end of 2025, making it the third-largest provider globally. Its Gen6 9650 SSD, built on G9 NAND, is already qualified on NVIDIA’s STX reference platform. The margin driver is HBM mix: higher-value HBM units absorb more wafer capacity per bit than commodity DRAM, which lifts blended gross margins as long as HBM pricing holds.

The primary risk is straightforward. If memory pricing normalizes faster than management expects, whether through new supply or a slowdown in AI capital spending, the P/E compression the model projects accelerates, and current investors absorb the downside.

Conclusion

One number will largely settle the debate: Micron’s fiscal Q3 2026 gross margin, due around June 24. Management guided approximately 81%. At or above that level, the HBM pricing power Bhatia described at JPMorgan shows up in the income statement, and the near-term bear case weakens. A result below 80% makes the TIKR model’s negative return outlook much harder to argue against.

What the JPMorgan conference adds is operational clarity that the stock price cannot: HBM4 ramping twice as fast as HBM3E, a secured ASML EUV deal, and SCAs anchoring multiyear demand against years of greenfield construction. These are facts on the ground, not projections. Whether they justify trading 24% above the Street’s mean target is the question June 24 begins to answer.
