Micron 4QFY26: Selling the Cycle Forward

Memory cycles eventually end.

That does not mean all their value has to disappear with them.

Micron is signing customers years forward, taking deposits and gaining better visibility into demand before new supply arrives.

The important question now is not whether today’s margins last forever.

It is what Micron does with the cash while they last.

If contracts support disciplined investment and excess cash retires shares at sensible prices, a temporary shortage can leave a permanent benefit per share.

My latest piece is about selling the cycle forward.

Micron’s opportunity is to turn customer commitments into cash that shareholders keep before supply catches up.

A customer signing a five-year memory agreement is making a judgment about more than memory prices. It is deciding that the cost of missing supply could exceed the savings from waiting for a better deal. For an AI infrastructure operator, that calculation includes processors, networking and power infrastructure whose productivity depends on having enough memory. Micron’s opportunity begins with that customer calculation; its investment case depends on what the company does with the resulting bargaining power.

In January, I argued that AI was making memory more strategically important and its most advanced forms harder to replace. In June, The Cycle Gets a Contract described Micron’s attempt to turn that importance into customer commitments before competition and new capacity caught up. Q4 advances both arguments but introduces a third: exceptional profits need not persist indefinitely if enough cash reaches shareholders while they last.

That is the position I would take after this quarter. Micron has bought greater visibility into future demand, and customers have accepted more obligations to secure supply. The task now is to convert that visibility into disciplined investment and capital returns. A longer shortage helps, but shareholder value ultimately depends on how much of its proceeds the company retains and how intelligently it uses them.

The Calendar and the Contract

Micron reported $54.23 billion of revenue, an 87% adjusted gross margin and $33.2 billion of adjusted free cash flow. The next-quarter revenue guide is $61.5 billion. On the surface, sequential growth falls from 31% to 13%; however, Q4 contained fourteen weeks and Q1 contains thirteen.

Revenue per week rose approximately 21.5% in Q4, and the Q1 guide implies another 22.1% increase. That is a materially stronger operating trajectory than the headline comparison suggests. It gives us evidence of continuing momentum, although one actual quarter and one forecast cannot establish a lasting growth rate. The more consequential evidence concerns what customers are committing to beyond the next report.

Strategic customer agreements increased from sixteen to twenty-six, covering an estimated over 35% of revenue through 2030. Financial commitments rose from $22 billion to $32 billion, predominantly deposit commitments; approximately $12.7 billion of customer deposits had been received by fiscal year-end. Management also disclosed approximately $150 billion of remaining performance obligations, calculated using committed volumes and minimum pricing for agreements with determined pricing frameworks.

The company describes why these agreements matter:

These multi-year take-or-pay agreements sharpen our long-term supply planning and enhance the durability and predictability of our strong financial performance. Further, they provide our customers supply assurance and deepen technology roadmap collaboration.

The final phrase connects the commercial change to January’s technical argument. Co-design can produce a qualified product that a customer is reluctant to replace; commitments make investment in that product easier to justify; successful manufacturing adds experience and improves delivery. If each generation strengthens the relationship, Micron acquires something more durable than an attractive spot price.

The boundaries matter because June’s language sometimes ran ahead of the disclosures. Financial commitments are not all collected cash, and a target for greater coverage is not existing protection. Today, three-quarters of agreement-covered revenue has a defined pricing framework, most such frameworks have floors and ceilings, and the remainder is periodically repriced. Separately, more than 75% of fiscal-2027 output is committed across agreement and non-agreement customers. That establishes substantial volume visibility without establishing equivalent profit protection.
