Shares plunged -5.2% to $437.49 the day after Micron delivered one of the most dominant earnings beats in semiconductor history, as investors confronted a familiar fear: the memory-chip giant is spending faster than even its explosive growth can comfortably absorb.

Micron's Q2 EPS of $12.20 crushed the $9.31 consensus by 31%, while revenue of $23.86B beat estimates by 24%.

Every product line and business unit hit new highs. Yet the stock fell because of what comes next on the balance sheet.

  • The Spending Jump That Spooked Wall Street

Micron raised its FY2026 capital expenditure outlook from $20B to over $25B , a 25% increase in a single quarter. Fiscal 2027 will be even bigger, with construction costs alone rising by over $10B year-over-year to build factories in Idaho, New York, Taiwan, and Singapore. In the cyclical chip industry, spending too much too fast can lead to a glut — a supply flood that crashes prices — if demand ever slows.

  • The Numbers Are Extraordinary, But Expectations Were Already Sky-High

Micron's stock tripled in 2025 and jumped another 62% year-to-date before this report.

The 52-week range stretches from $61.54 to $471.34 — a sevenfold swing reflecting how quickly AI hype got priced in. Investors concluded that strong earnings were "overshadowed by increased capital spending plans."

  • Demand Is Real — And Micron Can't Make Chips Fast Enough

The AI memory shortage is so extreme that Micron can only fill "50% to two-thirds of memory orders" from its largest buyers.

CFO Mark Murphy said the 81% gross margin guidance for Q3 reflects a multi-year AI investment cycle requiring more high-performance memory.

Q3 revenue guidance of $33.5B alone exceeds Micron's entire annual revenue for every year through fiscal 2024.

  • Analyst Reactions Are Split on the Price Tag

Cantor Fitzgerald hiked its target to $700 , while Goldman Sachs raised to just $400 — below today's price — maintaining a Neutral rating. That gap reveals the core debate: is Micron building for a durable AI-driven future, or pouring concrete into the next cyclical cliff? Analysts flagged concerns about whether margins near 81% are sustainable once billions in new factory costs hit depreciation lines.

The bottom line: Micron's demand story has never been stronger, but the market is asking whether $25B+ in annual spending — with more coming — will generate returns or repeat the boom-bust pattern that has defined memory chips for decades.
