Shares of Micron Technology climbed past $420 this week after the company raised its fiscal third-quarter guidance to levels that left Wall Street scrambling to update their models. Management guided Q3 revenue to $33.5 billion (plus or minus $750 million), with gross margins near 81% and EPS of $19.15 — more than triple the $9.3 billion reported a year earlier, with EPS far exceeding the ~$12.05 consensus. The message to investors: AI-driven memory demand isn't slowing down — it's accelerating.

  • Every Chip Already Has a Buyer Through Year-End. Micron has completed agreements on price and volume for its entire calendar 2026 supply of high-bandwidth memory (HBM) — the specialized chips that power AI processors. That means revenue for the rest of the year is essentially locked in under binding contracts, giving shareholders a rare degree of earnings certainty in a notoriously boom-and-bust industry. Micron forecasts the HBM market will grow roughly 40% annually through 2028, reaching about $100 billion — two years earlier than previously expected.

  • Margins Have Gone From Mediocre to Eye-Popping. In fiscal 2024, Micron operated with gross margins of approximately 22%. Guided Q3 margins of ~81% represent a complete transformation. Because HBM production requires twice as many wafers as standard memory, overall industry supply is constrained , handing Micron pricing power across all its products — not just AI chips. That margin expansion flows directly to the bottom line.

  • The $25 Billion Question: Can Micron Spend Fast Enough? Micron raised its fiscal 2026 capital expenditure forecast to above $25 billion to expand HBM and DRAM capacity — a figure that initially spooked investors. Shares fell ~4% the session after earnings on concerns over that spending bill and a downgrade from Summit Insights. The tension is real: build too slowly and Micron cedes ground to rivals Samsung and SK Hynix; build too aggressively and a future demand slowdown could crush returns on those factories.

  • A Cheap Stock for a Company Growing This Fast. Micron trades at roughly seven times forward earnings — unusually low for this growth profile — likely because investors still view memory as highly cyclical. If AI-driven demand continues reshaping the industry, valuation could eventually catch up to rapidly rising earnings.

Barclays has raised its target to $675; Stifel sits at $550. The bull case hinges on whether "supercycle" becomes "structural shift."
