Sold Out, on Contract, Years in AdvanceNarrow moat

Micron Technology (MU) — moat facet

Contracts delay the commodity dynamic rather than removing it; the conversation reopens at renewal.

The most consequential change in how Micron relates to its customers is not who they are but how they buy. Commodity memory has historically been purchased close to delivery at prevailing market prices, which is what makes the industry so violently cyclical — every buyer's decision is repriced continuously. High-bandwidth memory is sold differently: capacity committed well ahead, priced under multi-year contracts, against designs already qualified.

Take-or-pay obligations at 28 May 2026 (about $5B)Due within twelve months — 33%Due later — 67%About one-third within twelve months; minimum volumes and prices only. Micron Form 10-Q, May 2026
Two-thirds of the committed revenue lies beyond the next year.

That transforms the character of the revenue. Contracted capacity means a known price for a known volume across a period, which is why Micron's margins have been so much steadier through this cycle than the industry's history would predict, and why management could speak about capacity being sold out well in advance. It is closer to how a specialty manufacturer sells than to how a commodity producer does.

The limit is that a contract covers a period, not a franchise. When it expires the qualification competition reopens, and the customer — by then larger, better informed and with alternatives qualified — negotiates again. Contracts delay the commodity dynamic rather than removing it.

Watch the length and pricing of the next contract round rather than the current one. A supplier renewing at similar terms has a franchise; one renewing at lower prices has a contract that merely postponed the conversation — with one customer already at 17% of revenue1, that renewal matters more than any single quarter's pricing. The first binding version of the arrangement is now disclosed: take-or-pay agreements, most with fixed prices or price bands, carrying about $5 billion of remaining obligations at 28 May 2026, about a third due within twelve months.2

Moat trajectory: Widening

Contracted, sold-out HBM capacity has made Micron's margins far steadier through this cycle than the industry's history would predict, which is a genuine improvement in the quality of the revenue. Widening while the contracts run — and the thing to watch is the next renewal round, when a larger, better-informed customer with alternatives qualified negotiates again.

The number that tests this moat
Reported
Adjusted free cash flow
$18.3B in fiscal Q3 2026

Multi-year contracts turn sold-out capacity into cash that arrives on schedule. Cash flow that holds up when spot prices fall would show the contracts doing their job.

    Micron Form 10-K, FY2025 (Note 28, Certain Concentrations) — revenue from one customer was 17% of total revenue for 2025, primarily included in the Cloud Memory Business Unit segment; revenue from one customer was 10% of total revenue for 2024, primarily included in the MCBU, AEBU and CMBU segments; no customer accounted for 10% or more of total revenue in 2023; in each of the last three years approximately one-half of total revenue was from the top ten customers, and in 2025 over half; approximately one-half of total revenue was concentrated in the data center end market; increases in sales of system solutions may increase dependency upon specific customers because products with specifications unique to a customer increase reliance on that customer — FY2025 (ended August 28, 2025) · publ.
