Micron Technology Faces Valuation Debate Amid HBM Supply Constraints

What happened

Micron Technology reported fiscal second quarter 2026 results that significantly exceeded analyst expectations. Revenue reached $23.86 billion, surpassing consensus estimates by 22.28%, while non-GAAP earnings per share came in at $12.20 versus the expected $8.73. Net income grew 770.8% year over year during the quarter. Management guided fiscal third quarter 2026 revenue to approximately $33.5 billion with gross margins around 81%. CEO Sanjay Mehrotra stated that AI has fundamentally recast memory as a defining strategic asset in the AI era. The company disclosed that its HBM capacity is sold out through 2026, and it can fulfill only 50% to two-thirds of key customer demand. Cloud Memory operations ran at a 74% gross margin. Multiple analysts raised price targets following the results, with TD Cowen increasing its target from $660 to $1,500, RBC Capital Markets moving to $1,200, Cantor Fitzgerald setting a $1,500 target, and Susquehanna reaching $1,750.

Why it matters

The results highlight Micron's position in the AI-driven memory market, where demand substantially exceeds supply. The company is one of only three manufacturers producing advanced memory at scale globally, alongside SK Hynix and Samsung. This concentrated market structure provides meaningful pricing power. The sold-out HBM capacity through 2026 and the inability to meet full customer demand indicate sustained pricing strength. Management's guidance for $33.5 billion in fiscal Q3 revenue represents a 40% sequential increase and approximately 260% year-over-year growth. The expansion in gross margins to over 80% reflects the higher profitability of AI-focused memory products compared to traditional memory. Industry forecasts project the HBM market alone could reach approximately $100 billion by 2028. Analysts increasingly view AI memory as a structural growth market rather than a cyclical commodity business, which could justify higher valuation multiples than Micron historically commanded.

Bigger picture

The memory industry is experiencing a shift driven by AI infrastructure buildout. Every AI server requires dramatically more high-bandwidth memory, DRAM, and advanced storage than previous computing generations. Supply constraints persist because bringing new memory production capacity online takes years. Industry analysts now expect memory pricing strength to extend through late 2027, longer than previously anticipated. The traditional memory cycle pattern-where prices rise, manufacturers expand capacity, supply catches up, and prices fall-may be altered by structural demand increases from AI. Supply elasticity appears lower this cycle due to capital, packaging, and power constraints across the industry. Micron management has been signing longer-term customer agreements, providing revenue visibility uncommon in the historically cyclical memory sector. The company's position as the only major U.S.-based memory manufacturer adds strategic importance beyond pure market dynamics.

What to watch

Investors should monitor whether Micron's fiscal Q3 results meet the $33.5 billion revenue guidance and whether gross margins sustain levels above 80%. Pricing trends for HBM and DRAM through the second half of 2026 will indicate whether the extended pricing strength thesis holds. Customer agreement announcements and capacity expansion timelines will signal the company's ability to capture growing AI memory demand. Any signs of supply catching up to demand faster than expected could pressure the bull case. Management commentary on 2027 demand visibility and the mix shift toward higher-margin AI products will matter for longer-term earnings projections. Competitive dynamics with SK Hynix and Samsung in the HBM market warrant attention. Broader AI infrastructure spending trends and hyperscaler capital expenditure plans will influence memory demand forecasts.
