Micron Technology (MU) — 2026Q2 FY2026 Earnings Call Analysis

81% Gross Margins Cannot Buy More Wafers Today

They are printing 81% margins on demand they physically cannot fulfill until 2028.

Thesis: Micron has hit a physical capacity wall that guarantees peak pricing power through 2026. They are fulfilling only half of customer demand. Incremental price hikes fall straight to the bottom line because supply cannot expand without multi-year greenfield construction. Competitors face the exact same cleanroom bottlenecks. The market misprices this as a standard memory cycle. It is a structural capacity hostage situation.

Verdict: LONG — Conviction: MEDIUM

Catalyst: Gross margin expansion in fiscal Q3 and Q4 despite the HBM4 ramp. Additional 5-year SCAs announced to lock in the backlog.

Key Risk: Hyperscaler CapEx cuts before new fabs come online in 2027. This turns multi-year SCAs into unenforceable paper.

The Tell: Sanjay Mehrotra outright refused to detail downside protection in the new 5-year SCAs. When asked if the contracts limit gross margin downside, he invoked confidentiality. The backlog quality remains unproven if hyperscaler demand drops.

Detected Patterns

Structural Demand Shift: AI requires heavier memory configurations. Cleanroom constraints and HBM trade ratios create physical barriers to new supply.
Capacity Ceiling: Management admits they fulfill only 50-67% of key customer demand. The $10B capex increase will not yield volume until 2028. They are maxed out.

Friction Level: HIGH_FRICTION — The street disagrees on whether 81% margins reflect a permanent structural shift driven by AI physical limits or a cyclical peak preceding a 2028 supply glut.
