Micron's Capacity Crunch: Sold Out Through 2027 Fuels Record Rally

Micron's advanced memory chips are sold out for years, securing future revenue. The company is expanding into edge AI and new factories to meet booming HBM demand, projected to triple by 2028.

Micron Technology’s stock has soared nearly 475% over the past year, a staggering run that reflects more than just booming AI demand. The memory chip giant is now operating under a unique constraint: its manufacturing capacity for the most advanced products is fully booked for years to come. According to analysts at Lynx Equity, Micron’s production of High-Bandwidth Memory is sold out through 2027, extending beyond the company's own guidance of sold-out capacity through 2026.

This unprecedented visibility is reshaping the investment thesis. With binding contracts locking in sales for its highest-margin chips well into the future, uncertainty around future revenue is dramatically reduced. Lynx Equity has set a Street-high price target of $825, citing this clarity and expectations for 40% revenue growth in fiscal 2028, a stark contrast to consensus forecasts of stagnation.

The company’s recent financial performance underscores the demand surge. For its second fiscal quarter of 2026, Micron posted record revenue of $23.86 billion. Management anticipates another record in the current quarter, guiding for sales of $33.5 billion with a gross margin of 81%. The entire HBM production slate for calendar year 2026, including next-generation HBM4 chips, is already spoken for.

To capture this growth across multiple fronts, Micron is executing a dual-track strategy. While its core focus has been supplying data centers, it is now aggressively expanding into edge AI hardware. On April 8, the company announced a strategic investment in AI chip firm SiMa.ai, centered on integrating Micron’s LPDDR5X memory into SiMa’s edge-focused system-on-chip platform. This move targets latency-sensitive applications in robotics, autonomous systems, and industrial equipment, marking a significant expansion beyond the cloud.

Simultaneously, the company is racing to build more factories. In Taiwan, Micron is significantly expanding its Taichung site, including the acquisition of a facility from Powerchip for conversion to HBM and DRAM production. Further expansion in Tongluo is planned to boost capacity for the next generation of memory. This capital-intensive build-out, however, has drawn some analyst concern. Erste Group recently downgraded the stock to Hold, pointing to the high investment burden pressuring free cash flow.

Wall Street’s view remains divided despite the operational momentum. KeyBanc reaffirmed its Overweight rating with a $600 price target, projecting DRAM and NAND prices will jump 30% to 50% quarter-over-quarter in Q2 2026. In contrast, Citigroup cut its target from $510 to $425, though maintaining a Buy rating, citing a 6% price decline for standard DDR5 memory since mid-March.

The broader market context is undeniably powerful. The total HBM market is projected to explode from around $35 billion in 2025 to roughly $100 billion by 2028. Micron’s investments are designed to capture this wave from data centers to autonomous vehicles. Even after its monumental rally, the stock trades near its 52-week high of 402.20 euros with a forward price-to-earnings ratio of just over five, a deep discount to the industry average of 23. This valuation gap, against a backdrop of sold-out factories and record profits, presents a compelling paradox for investors.
