Micron Technology shares climbed roughly 45% in January after the company announced that its high-bandwidth memory (HBM) production for 2026 was fully sold out before the year began. Management revealed that all capacity at its new Lehi, Utah, HBM fabrication line and its Chippewa Falls, Wisconsin, expansion has been allocated to AI datacenter customers. To sharpen its focus on next-generation memory, Micron will discontinue its Crucial consumer SSD and DRAM branding by mid-2026, reallocating approximately $200 million in annual marketing and R&D spend toward AI-grade HBM and DDR5 products. The pivot underscores Micron’s commitment to capturing what it projects will be a $15 billion annual market for AI memory by 2028.

After more than doubling from its November low, Micron shares slipped over 3.5% on Tuesday as investors locked in gains following the steep rally. Trading volumes on the pullback day were 30% above the 90-day average, while options market data showed an unusual volume of short calls, suggesting hedging against a further retreat. Analysts point to the company’s planned capital spending of nearly $8 billion in fiscal 2026—up from $6.5 billion this year—as a potential drag on free cash flow, raising questions about margin pressure and wafer fab utilization if AI memory demand growth slows. Still, consensus estimates continue to forecast mid-20% revenue growth for the fiscal year ending September 2026.
