Key Highlights

  • Marvell Technology (Nasdaq: MRVL) custom silicon Revenue doubled in FY26, demonstrating accelerating hyperscaler adoption.
  • Management expects custom revenue to grow more than 20% year-on-year in FY27, and more than double year-on-year in FY28.
  • Several new custom design wins were announced in Q1 FY27, signalling strong forward revenue pipeline.
  • Custom programs are expanding through XPU attach initiatives including CXL and NIC products ramping in FY27.
  • FY28 Data Center revenue is expected to grow approximately 50% year-on-year, with custom silicon a primary contributor.

 

Analysis

When analysts model a semiconductor company, the question they most frequently wrestle with is whether the revenue being generated is recurring and compounding, or episodic and project-driven. Recurring Revenue compounds. Project revenue creates lumpy Earnings, disappointment cycles, and mean reversion. The reason this distinction matters so profoundly for Marvell Technology (NASDAQ: MRVL) is that the company has, embedded within its data center segment, a custom silicon Business whose revenue model is genuinely ambiguous — and the resolution of that ambiguity will determine the multiple the market assigns to the company over the next decade.

 

Custom silicon, in the context of Marvell, refers to application-specific integrated circuits designed in close collaboration with a hyperscaler customer. The customer specifies the architecture, the workload requirements, and often the process node. Marvell contributes the engineering expertise — in areas such as SerDes, high-bandwidth memory interfaces, PCIe controllers, and packaging — to tape out a chip that the hyperscaler then deploys at scale in its own data centres. The chip carries the hyperscaler's Brand internally but Marvell's silicon inside.

 

The Revenue Trajectory

Custom revenue doubled in FY26. That is the headline number from Marvell's earnings presentation, and it is a striking one. Management then guided custom revenue to grow more than 20% year-on-year in FY27 — notable because 20% on a base that already doubled represents genuine compounding, not a mean reversion. More importantly, the FY28 guidance calls for custom revenue to more than double year-on-year again, driven by what management described as multiple programme ramps.

 

The language of 'multiple programme ramps' is significant. A single programme ramp is a project. Multiple simultaneous programme ramps, each with its own multi-year production lifecycle, begin to look structurally more like a recurring revenue stream. If Marvell has won custom silicon sockets across multiple hyperscalers and multiple chip generations, then the aggregate revenue across the portfolio becomes relatively predictable even if any individual programme has a defined end date.

 

XPU Attach: The Hidden Multiplier

The Q4 FY26 earnings presentation introduced a term that deserves attention: XPU attach programmes. Marvell described CXL and NIC products ramping in FY27 as part of XPU attach initiatives. This means that when a hyperscaler deploys a custom accelerator chip designed with Marvell, the same Marvell relationship often extends to the connectivity fabric around that chip — the CXL memory controllers, the network interface cards, the PCIe retimers. One design win cascades into several product relationships across the same programme lifetime.

 

This attach dynamic transforms the Economics of the custom silicon business. Instead of a single chip at a single price, each programme generates multiple revenue streams across the system stack. The more deeply Marvell's technology is embedded in a hyperscaler's architecture, the higher the switching cost and the greater the revenue per programme over its lifetime.

 

New Design Wins: The Forward Revenue Indicator

In the Q1 FY27 results, management noted several new custom design wins. Design wins in the semiconductor industry typically precede revenue recognition by 18 to 36 months, given the time required to move from tape-out to qualification to Volume production. New design wins announced in early FY27 therefore represent the revenue pipeline for FY28 and FY29. The disclosure that these wins are plural and in progress is one of the most forward-looking datapoints in the recent earnings cycle.

 

The honest answer to the question posed in the title of this article — Royalty stream or project business — is that Marvell's custom silicon operation is currently in transition between the two. At its current scale and with its current programme Diversification, it is closer to a project business with royalty-like characteristics. If the FY28 doubling materialises and is followed by further programme wins in FY29, the business will have crossed the threshold into genuine recurring revenue territory. That transition, if it occurs, will justify a substantially higher terminal multiple for the company as a whole.
