## Moat

Marvell is the number-two custom AI silicon house behind Broadcom and the share leader in high-speed optical DSPs; the Google warrant deal ties a hyperscaler to it for years, but custom sockets are won and lost each generation and four or five customers carry the business.

### The Interconnect Specialist

Marvell's edge is **owning the electrical-to-optical boundary and co-designing custom chips with hyperscalers** — real, but a narrower franchise than Broadcom's:

- **Optical DSP Share Leader:** Marvell, via the Inphi acquisition, holds roughly 60% of the 400G-and-above PAM4 DSP market against Broadcom's 30%-plus, and its 3nm Ara was the first 1.6T DSP to sample. Almost every pluggable optical module in an AI cluster needs one, which makes Marvell a toll on the copper-to-optics transition rather than a bet on one accelerator.
- **Custom Silicon, Now Contracted:** Custom XPUs and attach chips are co-designed over multiple generations, and the August 2026 Google agreement spans inference accelerators, NICs, storage and memory-interface controllers around the TPU. Google's warrant vests one tranche per $500M of custom revenue through FY2033, up to $120B. But Broadcom remains the larger custom partner across more hyperscalers, and Marvell has lost generations before.
- **Concentration Is the Flip Side:** A handful of hyperscalers drive most of data-center revenue, so a single program shifting to Broadcom, MediaTek, Alchip or an in-house team moves the whole company. The moat is depth with each customer, not breadth across many.

**Moat verdict:** Marvell is a direct AI beneficiary: its strongest moat is the multi-generation custom-silicon embedding the Google warrant now contracts, backed by intact optical-DSP IP, bundling and talent. The vulnerability is concentration — Broadcom and in-house teams contest every socket — so the moat is as durable as the next design win.

### Top competitors

- **[Broadcom (AVGO)](https://investmoat.com/stocks/avgo):** The larger custom-accelerator partner and the main rival in optical DSPs and switching.
- **MediaTek (2454.TW):** Competes for hyperscaler custom-ASIC programs, including Google's TPU line.
- **[Credo Technology (CRDO)](https://investmoat.com/stocks/crdo):** SerDes, active electrical cables and optical DSPs for AI clusters.

## Growth

Q2 FY2027 (reported August 27) printed record revenue of $2.739B (+37% YoY, +13% QoQ) and non-GAAP EPS of $0.94 (+40%). Data center was $2.17B, 79% of revenue and +46% YoY. Non-GAAP gross margin was 58.9%, down 50bp YoY as custom silicon grows in the mix. Q3 is guided to $3.15B ±5% (+15% QoQ, >50% YoY) and $1.05–$1.15 of non-GAAP EPS. Management raised FY2027 to about $12B (~45% growth) and FY2028 to $18B (~50% growth), with custom revenue expected to more than double in FY2028 and accelerate again in FY2029. On August 18 Marvell issued Google a warrant for up to 58.97M shares at $206.58, vesting one tranche per $500M of Google custom revenue through FY2033. Marvell also closed the Celestial AI (photonic fabric) and XConn acquisitions for next-generation scale-up interconnect.

- **Revenue CAGR estimate:** 25–35%
- **Primary type:** TAM expansion
- **Margin trend:** stable
- **Key risk (high):** Marvell's growth rests on a few hyperscaler programs. If a next-generation custom accelerator goes to Broadcom, MediaTek, Alchip or an in-house team, or if hyperscaler AI capex pauses in 2027–28, the FY2028 $18B outlook breaks. Falsifiable: FY2028 revenue below $15B, or custom revenue failing to double in FY2028, would mean the custom thesis is not on track. The Google warrant also dilutes holders by up to ~59M shares as revenue milestones vest.
- **Drivers:**
  - Custom XPU and attach silicon — Expected to more than double in FY2028; Google agreement covers accelerators, NICs, storage and memory-interface controllers (accelerating)
  - Electro-optics (PAM4 DSP, TIA, drivers) — ~60% share of 400G+ PAM4 DSPs; 3nm 1.6T Ara sampling and ramping (accelerating)
  - Enterprise networking, carrier, auto/industrial — 21% of Q2 revenue; recovering from the 2024 inventory correction but growing far slower than data center (stable)
- **Score derivation:** Base 90 (25–35% CAGR, midpoint 30%) + 2.7 trajectory (custom silicon and electro-optics accelerating; enterprise, carrier and auto/industrial stable) + 0 margin (stable: non-GAAP gross margin 58.9%, down 50bp YoY as lower-margin custom grows, while operating leverage lifts EPS faster than revenue) − 10 high risk (four or five hyperscalers drive most of data-center revenue; one lost custom generation, as with past AWS programs, cuts the growth path sharply; same capex-cycle risk as CRDO) = 83

## Valuation

At $264.21 (September 30 close, ~$233B market cap on ~882M shares), Marvell sits between the $160 bear and $280 base, about 87% of the way from bear to base, for a valuation score of 68. That is ~38× the ~$6.9 FY2028 consensus EPS: the price already assumes most of the $18B outlook lands.

**Fair value:** ~$280 — The base of $280 is ~40× FY2028 consensus EPS of ~$6.9, or ~30× a ~$9 FY2029 if custom accelerates as guided — a premium multiple for a growth rate few semiconductor names match. The bear uses the low FY2028 estimate (~$5.30) at ~30×. Add on weakness toward the $200s; the warrant's $206.58 strike is a useful marker of where Google was willing to commit.

| Multiple | Value | Note |
| --- | --- | --- |
| Forward P/E (FY2028) | ~38× | consensus FY2028 non-GAAP EPS ~$6.88 (range $5.30–$8.49) |
| Run-rate P/E | ~60× | Q3 FY2027 non-GAAP EPS guide $1.10 midpoint, annualised |
| PEG Ratio | ~1.3× | FY2028 P/E ÷ 30% CAGR midpoint |
| Price / Sales (FY2028) | ~13× | ~$233B ÷ $18B FY2028 outlook |

Marvell is priced as a growth compounder, not a cyclical chip supplier. A PEG near 1.3× is reasonable only if the FY2028 outlook and the custom doubling both land; a lost program would leave a ~38× multiple on lower earnings. _(as of September 30, 2026)_

## Price scenarios

### Bear — $160

A custom program slips or moves to a rival and AI capex digests in 2027; FY2028 lands well short of $18B and the multiple compresses.

- A next-generation hyperscaler accelerator goes to Broadcom, MediaTek or an in-house team
- 1.6T optics ramp meets price competition from Broadcom and Chinese DSP entrants
- FY2028 EPS lands near the $5.30 low estimate and the stock trades at ~30×, giving about $160

### Base — $280

FY2028 lands near $18B, custom revenue doubles as guided, and the market keeps paying a growth multiple.

- Q3 and Q4 FY2027 land near guidance, keeping FY2027 at ~$12B
- Google programs vest the first warrant tranches, confirming the custom ramp
- FY2028 EPS near $6.9 at ~40×, giving about $280

### Bull — $400

Custom accelerates again in FY2029, Celestial AI wins scale-up optical sockets, and Marvell is valued alongside Broadcom.

- A new hyperscaler custom XPU win beyond Google and the existing programs
- Celestial AI photonic fabric designed into a scale-up AI system
- FY2028 EPS near the $8.49 high estimate at ~47×, giving about $400
