Major ClientsNarrow moat

Vertiv Holdings (VRT) — moat facet

No customer reaches 10% of revenue, and the risk factors still say the customers write the terms — both are true, which is the whole story.

Vertiv's fiscal 2025 10-K contains no customer-concentration table. No buyer reaches the 10% of revenue that would require disclosure, which on the face of it puts Vertiv in the comfortable position Apple occupies — many customers, none able to dictate terms.

Diffuse by name, concentrating by geography, by sector and by counterparty quality.

The risk factors say the opposite. Large customers, the filing states, "comprise a material portion of our customer base and generally have greater purchasing power than smaller customers," with "enhanced leverage that allow them to require more favorable terms and conditions," substantial penalties for delivery or product failures, and demands for stringent performance guarantees — with "less leverage with large customer contract terms" listed among the company's principal risks1. Both things are true at once: no single customer is 10% of revenue, and the customers still set the terms.

The filing does classify who they are, and the taxonomy is more useful than a percentage. Vertiv sells into data centers — split into cloud/hyperscale (Microsoft, AWS, Google Cloud), colocation (Digital Realty, Equinix, Compass, QTS), neocloud (CoreWeave, Nebius) and enterprise — plus communication networks and commercial and industrial applications2. Those four data-center classes have very different balance sheets, which is the subject of the second page here.

Two numbers frame the rest. Backlog reached $15.0 billion at the end of 2025, roughly double the $7.2 billion a year earlier3 — and customers can in some circumstances reduce or defer it. And the Americas went from 56% to 62% of net sales in a single year4: this customer base is concentrating by geography even as it stays diffuse by name. The cyclical and valuation consequences of all this have their own root threat; these pages are about who the buyers are and what power they hold.

Moat trajectory: Narrowing

The customer base is becoming less diversified in every dimension except the one that gets disclosed. No buyer crosses 10% of revenue, so the concentration table stays empty — while the Americas went from 56% to 62% of sales in a year, the fastest-growing customer class is the least creditworthy, and the largest buyers hold contractual leverage the filing describes at length. Diffuse by name, concentrating by geography, by sector and by counterparty quality.

The number that tests this moat
Reported
Americas sales growth
+29.2% to $2,070.8M in Q2 2026

No customer reaches 10% of sales, but the large cloud buyers are concentrated in this region. Growth that depends ever more on the Americas makes Vertiv more exposed to those few buyers' plans.
