Ten Customers, Eighty-Two PercentThin moat
Marvell Technology (MRVL) — moat facet
The most concentrated customer base in this collection — and the receivables, at 73% from four names, are tighter still.
Marvell's ten largest customers, distributors and direct customers together, were 82% of total net revenue in fiscal 20261. For comparison, the concentration that makes Nvidia's filings notable is two customers at 36%, and Arista's much-discussed dependency is roughly 42% from two. Marvell sits at the extreme end of this collection.
The credit picture is tighter than the revenue picture. Four customers represented 73% of gross accounts receivable at the fiscal year end, against 72% a year earlier2 — meaning the money Marvell is owed at any moment is concentrated in fewer hands than the money it earns. The company notes that it monitors creditworthiness and that its distributors sell on to diverse end customers, which is a fair mitigation and not a removal of the risk.
The honest defence is that this is what selling to hyperscalers looks like. There are perhaps ten organisations on earth building computing at this scale; a company that sells to them successfully will show exactly this profile, and the alternative — a diversified customer base in a market that does not exist — is not on offer.
The defence has a limit, which is that concentration determines what a single lost program costs. Watch the ten-largest figure over several years. Rising through the boom would mean Marvell is riding the cycle rather than building a franchise beneath it.
Concentration has risen through the boom, which is the wrong direction for a company arguing that it is building a durable franchise rather than riding a capital-spending cycle. Receivable concentration ticked up too, from 72% to 73% across four names. None of this is alarming while the customers are the best-capitalised companies on earth. It becomes alarming the moment one of them changes its mind about a program.
The credit exposure is more concentrated than the revenue: 73% of gross accounts receivable sat with four customers at the fiscal 2026 year end, against 72% a year earlier. Marvell notes its distributors sell on to diverse end customers, which mitigates rather than removes the exposure. Watch whether the count of names behind that figure ever rises.
