Micron Pulls Off a Double Play: Historic US Production Ramp Meets All-Out HBM4 Sell-Out

Samsung strike threatens 4% of global DRAM supply; Micron secures HBM4 for 2026, starts US 1? DRAM production, $200B plan lifts stock 670%.

The semiconductor world is watching two dramas unfold simultaneously. As roughly 48,000 Samsung workers prepared to walk off the job on May 21, Micron quietly locked up every last wafer of its next-generation high-bandwidth memory for all of 2026. The shifting balance of power in memory chips just got a hard shove.

South Korea’s industrial action threatens to knock out up to 4% of global DRAM supply, according to TrendForce. That blow comes just as demand for premium memory — fueled by artificial intelligence infrastructure — is already outpacing what factories can deliver. Prices are feeling the heat: a standard DDR5 module has climbed 11% since mid-May to $1,350.

Micron, by contrast, is operating from a position of strength it hasn’t held in years. The company’s entire HBM4 output for 2026 has been committed through binding contracts. Customers are now locking in allocations for three to five years, replacing the old quarterly agreements. The shift smooths revenue volatility and gives management rare visibility into future cash flows.

On the J.P. Morgan Technology Conference stage in Boston, executives underscored the improving financial trajectory. For the third fiscal quarter, they flagged a record free cash flow — a milestone that would mark a decisive departure from the boom-and-bust cycles that have long dogged the memory industry.

But the headlines this week came from Virginia. Micron fired up production at its Manassas facility using the 1? DRAM process node — the most advanced memory manufacturing ever performed on US soil. CEO Sanjay Mehrotra welcomed Commerce Secretary Howard Lutnick, US Trade Representative Jamieson Greer, and two Virginia senators on May 22 to mark the occasion.

The plant will quadruple its DDR4 wafer capacity once fully ramped. The chips are destined for sectors that prize long product life and secure domestic supply: automotive, defense, aerospace, industrial, networking, and medical equipment. The 1? node represents the industry’s leading DDR4 technology, and the company is betting heavily that in-house, US-based production will become a competitive moat.

That bet comes with an eye-watering price tag. Micron plans to invest roughly $200 billion across its US sites — including existing operations in Idaho and New York alongside the expanded Virginia campus. The combined projects are expected to generate around 90,000 jobs.

The investment narrative has electrified investors. Over the past twelve months, Micron shares have surged nearly 670%. Year-to-date gains exceed 140%. The stock closed Friday at €647.30 in Europe, about 6% below its 52-week high of €685. A glance at the 52-week low of roughly €82 underscores the magnitude of the rally.

Wall Street is scrambling to keep up. Melius Research lifted its price target to $1,100, Bank of America to $950, and Citigroup to $840 — roughly double its prior estimate. All three cite tight memory supply and insatiable demand from AI workloads. Micron’s HBM3E products are already deployed on multiple AI accelerator platforms, and management expects supply constraints across HBM, DRAM, and NAND to persist beyond 2026.

The rally has reignited talk of a stock split — last done in May 2000. No official plans have been announced. Attention instead is fixed on the upcoming quarterly report. Analysts project revenue growth of more than 260% year over year, with earnings per share crossing $19.

The real test will come when those numbers land. If HBM shipment volumes and pricing match expectations, the analyst targets — as lofty as they appear — might still have room to run.
