Google deal accelerates the AI master plan
- Data Center made up 79% of Q2 FY27 revenue, solidifying Marvell as a key AI infrastructure supplier.
- Management raised fiscal 2027 revenue guidance to roughly $12 billion and fiscal 2028 guidance to about $18 billion.
- A major expanded warrant agreement with Google validates the custom silicon and XPU attach strategy.
- Custom silicon could more than double in fiscal 2028, but the fast ramp is capping gross margins near 58%.
- The valuation leaves very little room for error if large cloud programs slip or supply tightens.
Massive targets, zero room for error
Marvell's growth story accelerated again in Q2 FY27. Management lifted fiscal 2027 revenue guidance to roughly $12 billion and fiscal 2028 guidance to about $18 billion. The massive ramp is fueled by a new expanded warrant agreement with Google, which secures Marvell's role in the custom silicon ecosystem for AI inference, storage, and networking.
The bull case centers on scale. As AI data centers grow, they need faster links between chips and servers. Marvell sells those links through optical chips, electrical cables, switches, and custom ASICs. A custom ASIC is a chip built for one customer's special job. Data Center revenue is now expected to grow more than 60% in fiscal 2027.
The bear case is simple. The stock is priced for perfection, and the custom silicon boom comes with a cost. Because custom chips carry lower gross margins than standard products, gross margins are expected to stay flat in the 57% to 58% range through fiscal 2028. This means the company needs massive volume to hit its operating profit targets.
The next test is the October 6 Investor Day, where a new CFO will outline long term margin targets. Investors will also watch to see if custom silicon really more than doubles in fiscal 2028 and if scale-up optics hits a $1 billion run rate quickly.
Selling the data pipes for AI clusters
Marvell is a fabless chip company. That means it designs chips but uses outside partners in Taiwan to make them. Its main customers are large cloud and networking companies that need fast, low power data movement.
The company makes money in two main ways. First, it sells merchant products, which are standard chips such as optical DSPs, switches, and storage controllers. These carry higher gross margins. Second, it builds custom silicon for Tier 1 cloud customers. These custom chips carry lower gross margins, but customers often pay non recurring engineering fees to help cover the heavy design costs.
The moat comes from hard to copy chip designs and years of trusted work with major cloud buyers. Key building blocks include high speed SerDes, ARM compute blocks, silicon photonics, and advanced packaging. The Celestial AI acquisition added Photonic Fabric technology, aimed at moving data inside AI clusters with less delay.
The weak point is heavy concentration. A few customers and programs matter a lot. If one large cloud provider changes its roadmap, Marvell can lose revenue faster than a broad chip supplier.
Where the chips fit
Electro-optics and interconnect
These chips help data move across optical modules, cables, and data center links. They are a massive driver as AI clusters require faster connectivity.
Custom silicon and ASICs
Marvell designs special chips for large cloud customers, including inference accelerators for the Google TPU ecosystem. Management expects custom revenue to more than double in fiscal 2028.
Switching and networking
Ethernet switches and related networking chips move traffic inside data centers, campuses, and carrier networks.
Storage controllers
Marvell sells controllers used in cloud, enterprise, and consumer storage devices. Storage remains a steady part of the data infrastructure bundle.
OCTEON DPUs and carrier chips
DPUs, PHYs, and carrier networking chips serve enterprise and telecom buyers. These markets are highly cyclical.
Photonic Fabric from Celestial AI
This acquired technology is aimed at optical connections inside AI systems. Management expects scale-up optics to become a major revenue driver.
Now completely dominated by data centers
Segment mix uses Q2 FY27, the quarter where Data Center revenue hit a record $2.17 billion. The company is highly concentrated, with Data Center making up 79% of total revenue.
What could break the story
Custom program slip
High impact · Medium oddsA large part of the upside depends on custom silicon programs for Tier 1 cloud customers. If a new XPU program is delayed, canceled, or ramps below plan, the fiscal 2028 target of $18 billion becomes harder to hit.
Lower margin custom mix
High impact · High oddsCustom silicon carries lower gross margins than standard merchant chips. As custom ramps aggressively, gross margins are capped in the 57% to 58% range through fiscal 2028, requiring flawless volume execution to hit profit targets.
Cloud capex pause
High impact · Medium oddsMarvell is tied closely to AI data center spending. If large cloud companies slow capital spending, orders for interconnect, switching, and custom silicon could fall short.
Customer concentration
High impact · High oddsRevenue is packed into a small group of buyers. In Q1 FY27, one distributor was 45% of net revenue and one direct customer was 16%.
Taiwan and Asia supply exposure
High impact · Medium oddsMarvell depends on third party manufacturing and assembly partners, with major exposure to Taiwan. Sales shipped to customers with operations in Asia were 83% of net revenue in Q1 FY27.
Celestial AI integration
Medium impact · Medium oddsThe Celestial AI deal is a massive bet on photonic interconnect. If Marvell cannot integrate the team and technology, the deal could dilute returns or lead to impairment.
In one breath
What does Marvell Technology do?
Marvell designs chips for data infrastructure. Its main growth areas are AI data centers, optical interconnect, networking, storage, and custom chips for large cloud companies.
Why is Marvell linked to AI?
AI clusters need huge amounts of data to move quickly between chips, servers, and data centers. Marvell sells the chips that help move that data, and it also builds custom silicon for cloud customers like Google.
What is the biggest risk for MRVL stock?
The biggest risk is execution against a very high growth plan. Management is targeting about $18 billion of revenue in fiscal 2028, so a custom chip delay or cloud spending slowdown could hit the stock hard.
