Micron Shares Surge 10% on Record AI-Driven Sales and Sold-Out 2026 HBM Output

Micron Technology shares surged more than 10% after the memory-chip maker posted record quarterly results and said its entire 2026 output of high‑bandwidth memory (HBM) chips was effectively sold out, underscoring how the AI boom has flipped a once‑cyclical industry into acute shortage.nasdaq +1 The company forecast second‑quarter revenue of about $18.7 billion and record adjusted earnings of $8.42 per share, far above Wall Street expectations.fool +1

Micron reported fiscal first‑quarter 2026 revenue of $13.64 billion, up roughly 57% year over year, with adjusted earnings per share of $4.78.fool Gross margin jumped to 56.8%, an 11‑point sequential improvement, and free cash flow hit a record $3.9 billion as prices for advanced memory products climbed.fool DRAM accounted for 79% of sales at $10.8 billion, rising about 69% from a year earlier, while NAND revenue increased 22% to $2.7 billion.fool

AI Memory Shortage Turns Into a “Sold Out” Story

The rally was driven by Micron’s disclosure that it has signed agreements covering all of its planned 2026 HBM supply, a premium memory used alongside GPUs in AI data centers.cnbc +1 Chief business officer Sumit Sadana said Micron was “more than sold out” and that no major customer was receiving 100% of the memory it wanted, signalling a structural shortfall that could persist for years.cnbc +1

AI‑related products are reshaping Micron’s mix and pricing power. Management projected the HBM market could reach about $100 billion by 2028, implying compound annual growth near 40% from mid‑decade levels.cnbc To keep up, Micron lifted its 2026 capital‑expenditure plan to roughly $20 billion from about $18 billion, funding new fabs and advanced packaging lines focused on AI‑grade memory rather than consumer products.fool +1

Wall Street Reprices the “Memory Supercycle”

The blowout guidance prompted a swift re‑rating from analysts who had questioned whether AI demand was already priced into the stock after a triple‑digit gain this year.zacks +1 Bank of America upgraded Micron to Buy, citing evidence of a “longer AI‑led memory upcycle,” while JPMorgan and Morgan Stanley raised targets, with one note calling the quarter one of the strongest revenue and profit surprises in U.S. chip history outside Nvidia.yahoo +1

Micron’s pivot away from its Crucial consumer brand, announced earlier this month, reinforced the view that the company is concentrating on higher‑margin enterprise and AI infrastructure customers even as that increases exposure to hyperscaler spending cycles.reuters +1 Critics warned that memory’s history of boom‑bust pricing, combined with aggressive capacity expansion across the industry, could eventually turn today’s shortage into oversupply, but most near‑term commentary framed the results as validation that AI demand remains resilient.techi +1

The Bigger Picture

Micron’s quarter crystallized a broader market narrative: AI’s build‑out is migrating profits from GPU makers alone to the components that feed them, especially high‑end memory. With 2026 HBM already spoken for and guidance pointing to record profitability next quarter, investors are treating the company as a central beneficiary of an AI infrastructure “supercycle”—and using its results as a barometer for the durability of the entire AI trade.cnbc +1
