The Buyer Who Told Its Own Investors Memory Costs Too MuchThin moat

SK hynix (SKHY) — moat facet

Nvidia guided its gross margin down to 74 percent because of memory prices -- a customer conceding in public that its supplier has the upper hand, and simultaneously announcing its motive to fix that.

The clearest public evidence of SK hynix's pricing power did not come from SK hynix.

A customer conceding in public that its supplier holds the upper hand.

Nvidia guided its third-quarter gross margin down to around 74.0%, and attributed the compression to memory costs1. In the same filing it disclosed purchase commitments and supply obligations rising from about $119 billion to about $279 billion2 — a company locking in components years ahead because it has concluded they will be scarcer and dearer later.

Read from the other side of the transaction, that is a customer publicly conceding that its supplier has the upper hand, and simultaneously guaranteeing that supplier's volume. Very few companies in this collection can point to a buyer of that stature making the argument for them.

It is also, precisely because it was said in public, the strongest available signal of what happens next. A buyer that has told its shareholders its margins are being taken by a component is a buyer that will fund every alternative available: a second source, a third, a different memory architecture, a redesign that needs less of it. None of those work quickly, and all of them are now motivated.

The single number to watch is Nvidia's gross margin. If it recovers while its accelerator volumes keep rising, memory prices have turned — and SK hynix's 76% operating margin3 turns with them, in the same direction, at the same time.

Moat trajectory: Narrowing

A customer that has publicly attributed its own margin compression to memory prices is a customer that will fund every alternative available. The statement is recent and the motive is now permanent.

Nvidia gross margin guidance
74.0% — guided down on memory costs

A customer publicly attributing its own margin compression to a component is a customer that will fund every alternative available. It is also the clearest third-party evidence of SK hynix's pricing power. If Nvidia's gross margin recovers while its volumes rise, memory prices have turned.
