IP, Process Access & Engineering DepthNarrow moat

Underneath both of Marvell's data-center businesses sits the same asset: a library of high-speed interface intellectual property and the organisational capability to tape out very large chips at the newest process nodes. It is the least visible part of the company and arguably the most durable.

The IP that matters most is SerDes — the circuitry that serialises data and drives it down a wire or into an optical engine at hundreds of gigabits per second. Developing it takes years and repeated silicon iterations, because the behaviour at these speeds cannot be fully simulated; it has to be built, measured and corrected. A company with proven SerDes at the current node has something a competitor cannot buy and cannot quickly replicate, and it is reusable across every custom program, every switch and every optical DSP.

Alongside it sits process access. Leading-edge capacity at TSMC is allocated, not simply purchased, and being an established large customer at the newest node is a real advantage when a hyperscaler asks who can build its chip soonest.

The limits are cost and talent. Each node transition raises development expense sharply, which is why this industry keeps consolidating — and why a company competing against a much larger rival must spend proportionally more of its revenue to stay level — a burden carried comfortably while revenue grew 42% to $8.195 billion¹, and considerably less so if growth stops.
