New York, February 12, 2026, 07:52 EST — Premarket
- Micron shares surged further following an executive update on HBM4 production and shipments
- Samsung and SK Hynix accelerate the rollout of next-gen AI memory with this latest move
- Investors will be watching Micron’s mid-March earnings closely, eager for updates on volume and pricing.
Micron Technology, Inc. shares climbed 3.2% to $423.61 in premarket trading Thursday, building on Wednesday’s 9.9% jump to $410.34. Investors reacted strongly after the company revealed its next-gen HBM4 memory is already shipping. 1
The timing is critical since high-bandwidth memory has stepped out of the sidelines. HBM, a stacked DRAM variant placed alongside AI processors, speeds up data transfer and usually commands a premium over regular memory, especially when supply is limited.
This market runs on tight calendars. If a supplier misses a quarter, major customers can pivot orders fast — and those who deliver get locked into next year’s production plans well before any revenue hits the books.
Micron CFO Mark Murphy told investors the company has “commenced customer shipments of HBM4,” saying it’s “a quarter earlier” than the timeline Micron set back in December. Executives also pushed back against what Murphy called “inaccurate reporting.” Meanwhile, Lynx Equity Strategies analyst KC Rajkumar said the update should “put to rest the noise” surrounding Micron’s HBM4 readiness. 2

Samsung Electronics announced it has begun shipping its latest HBM4 chips, with chip chief Song Jai-hyuk describing early feedback as “very satisfactory.” The company says these chips operate at 11.7 gigabits per second, with speeds up to 13 Gbps possible. Samsung’s shares jumped 6.4% in Seoul following the news. 4
Morgan Stanley boosted its price target on Micron from $350 to $450, maintaining an Overweight rating, according to Barron’s. 5
Traders are now focused on one key question: will “shipping” translate into steady volume, and at what cost? If customers start vetting multiple suppliers like Samsung, SK Hynix, and Micron, the stock could swing just as quickly the other way.
The downside risk is still present. Memory is cyclical, and a rapid ramp-up can hit snags like yield issues, delays in customer qualification, or a slowdown in demand if AI server spending falters.
Micron is set to release its next earnings report on March 18, per Yahoo Finance’s earnings calendar. Investors will likely focus on HBM4 volumes, pricing trends for DRAM and NAND, and Micron’s plans for capacity expansion through 2026. 6
