The Agreements Kioxia Is Trying to SignThin moat

Kioxia Holdings (285A) — moat facet

Kioxia is trying to contract half of 2028 while SK hynix states it holds no backlog at all -- the two largest memory makers moving in opposite directions on the same question.

One of the most interesting slides Kioxia has published is about contracts, and it reads as a direct answer to how this industry normally works.

Two memory makers, opposite directionsKioxia's target~50% of calendar 2028 under long-term agreementSK hynix's disclosureNo order backlog under long-term contractsSK hynix pricesMonthly and quarterly, by mutual agreementWhich suits a pure playThe one with the scheduleA company with one product and fixed costs needs visibility more than upside.
The two largest memory makers disagree about how memory should be sold.

Management has set a target of roughly 50% long-term agreement coverage for calendar 2028 with key customers, to improve revenue visibility and deepen engagement with hyperscale cloud and enterprise AI buyers1. The investor day framed the same idea as securing multi-year agreements to improve the quality of profit rather than only its level2.

Set that against SK hynix, whose own report states plainly that it agrees volumes and prices monthly and quarterly and holds no order backlog under long-term supply contracts. The two largest producers of memory in the world are moving in opposite directions on the single most important commercial question in the business.

Kioxia's version is the more conservative bet, and for a pure play it is the right one. Contracted volume converts a violent market into a schedule, and a company with one product and fixed costs needs the schedule more than it needs the upside.

It is also, today, an aspiration. Nothing in the current results reflects it.

The number to watch is the contracted proportion itself, if Kioxia ever discloses it. A target for 2028 announced in 2026 is a statement of intent, and the industry has broken more of those than it has kept.

Moat trajectory: Widening

A target of roughly 50% long-term agreement coverage for calendar 2028 is a deliberate move away from how memory has always been sold. It is an intention rather than a contracted position, but the direction is unambiguous.

The number that tests this moat
Reported
Long-term agreement coverage targeted for 2028
~50% — against an industry norm of none

SK hynix's own report states it agrees volumes and prices monthly and quarterly with no order backlog under long-term contracts. The two largest memory makers are moving in opposite directions on the most important commercial question in the business. Watch whether Kioxia ever discloses the contracted proportion, and on what terms.

A Contract Signed in a Shortage Is Priced Like a Shortage
Buyers commit when they are frightened, and a sophisticated buyer signing at the peak negotiates the flexibility back in.
