Key takeaways

  • Micron's fiscal Q4 revenue was $54.23 billion, versus $11.32 billion a year earlier, with GAAP gross margin of 86.8%.
  • Fiscal 2026 revenue reached $133.19 billion and net income $84.97 billion, against $37.38 billion in revenue for fiscal 2025.
  • Guidance for fiscal Q1 2027 is $61.5 billion plus or minus $1.5 billion at roughly 86% gross margin.

Micron Technology reported fiscal fourth-quarter revenue of $54.23 billion on September 30, nearly five times the $11.32 billion it booked a year earlier and well ahead of the roughly $51 billion analysts had expected, according to LSEG consensus cited by Pulse 2.0. GAAP gross margin hit 86.8%. For a company that has historically swung between boom and bust, the numbers describe something different: a supplier with more pricing power than almost any chipmaker in the industry.

The quarter in numbers

Micron's own release shows operating income of $43.75 billion, or 80.7% of revenue, and GAAP net income of $37.70 billion, or $32.87 per diluted share. Non-GAAP earnings were $33.42 a share. Operating cash flow was $43.97 billion, up from $25.39 billion the previous quarter, and adjusted free cash flow came to $33.20 billion because net capital spending was only $10.77 billion in the quarter.

For the full fiscal year, revenue was $133.19 billion against $37.38 billion in fiscal 2025, and net income was $84.97 billion. Guidance for the first quarter of fiscal 2027 is $61.5 billion, plus or minus $1.5 billion, with GAAP gross margin of about 85.95% and GAAP earnings of $37.84 a share, plus or minus $1. CEO Sanjay Mehrotra said the company expects an even stronger fiscal 2027.

Why margins look like software

Memory is a commodity business, so its margins track the gap between demand and supply. Micron's gross margin was about 74.4% in the fiscal second quarter and reached 86.8% in the fourth. The mechanism is the one that has already pushed up prices for PCs and consoles: AI servers consume large volumes of high-bandwidth memory, which uses more wafer area per bit than ordinary DRAM, while new fabrication capacity takes years to build. When buyers cannot get enough, contract prices rise and nearly all of the increase falls to the bottom line.

Why it matters

Memory has become a swing factor for the whole hardware stack. Micron's revenue gain of roughly $43 billion in a year is larger than the annual sales of many well-known chip companies, and it comes out of the budgets of everyone who builds devices: phone makers, PC vendors, console makers and cloud providers. Higher component costs are already visible in consumer pricing, which DealTrade has covered separately.

It also shifts the AI-spending debate. Part of the hyperscaler capex headline is now simply paying more for the same bits. Investors who worried about an AI bubble have a harder time dismissing a supplier that is converting demand into more than $33 billion of quarterly free cash flow.

What to watch

  • Capex response. Micron spent $27.37 billion net on capital for fiscal 2026; larger budgets would signal the industry expects the squeeze to end.
  • Korean peers. Samsung and SK hynix results, which tend to follow Micron, will show whether the pricing is industry-wide.
  • Margin ceiling. Guidance implies gross margin slipping slightly to about 86%, the one soft spot analysts noted.
  • Demand elasticity. Whether device makers cut memory content or raise prices further.
