RBC Capital Markets is telling clients that chipmaker Marvell Technology is positioned to beat Wall Street's fiscal second-quarter expectations and raise its third-quarter guidance when it reports results on August 27th. The bank's optimism is rooted in strength in Marvell's optical networking business and the company's custom AI chip deals with Amazon and Google.
What's driving the expected beat
Marvell makes semiconductors used in data centers, networking equipment, and storage. A key part of its business is optical networking—the technology that moves data between servers using light—which has been a bright spot as cloud providers and AI companies build out massive computing infrastructure. RBC expects that strength to help Marvell deliver what it calls "a slight beat" against current Q2 estimates.
Beyond the quarter itself, the bank is looking ahead. RBC forecasts that Marvell will raise its Q3 guidance by 2% to 4%, supported by the custom chip programs it has with two of the biggest cloud players. These "XPU" deals—custom processors designed for specific AI workloads—are becoming an increasingly important revenue stream for Marvell, as hyperscale customers look for alternatives to off-the-shelf chips.
The bigger picture: custom chips and sticky customers
RBC's more significant point is about durability. Custom chips for large cloud companies involve long testing cycles and high switching costs. Once a customer designs a chip into its data centers, it's not easy to swap in a competitor's product. That means Marvell's revenue from these deals could be more predictable and longer-lasting than typical semiconductor sales, which often swing with the boom-and-bust cycle of the industry.
This is part of a broader trend in the AI chip market. While Nvidia dominates the market for general-purpose AI accelerators, companies like Amazon and Google are increasingly designing their own custom chips to optimize performance and cost for their specific workloads. Marvell has positioned itself as a key partner in this effort, helping these giants bring their designs to life. The company's expanded deal with Google has been a notable driver of investor enthusiasm.
Capacity constraints could temper the upside
RBC also flags a potential headwind: tight chipmaking capacity. Marvell, like many chip designers, relies on external foundries to manufacture its products. With demand for AI-related chips surging across the industry, available manufacturing capacity is scarce. This could limit how much upside Marvell can deliver in the near term, even if demand is strong. The bank notes that this constraint might keep the Q3 guidance raise at the lower end of the 2-4% range.
What it means for investors
For everyday investors, the key takeaway is that Marvell's growth story is increasingly tied to the AI buildout. The company's custom chip deals with Amazon and Google are not just one-off wins; they represent long-term partnerships that could provide a more stable revenue base. The warrant included in the Google deal also gives Marvell a potential stake in Google's success, aligning the two companies' interests.
However, investors should be aware of the risks. The semiconductor industry is cyclical, and Marvell's fortunes are closely tied to capital spending by cloud providers. If those companies pull back on data center investment, Marvell could feel the pinch. Additionally, the capacity constraints RBC mentions could persist, limiting growth even if demand remains strong.
Marvell's stock has been volatile, reflecting the broader swings in AI-related tech names. The company's shares jumped recently amid news about its Google deal, but the sector remains sensitive to headlines about AI regulation and spending. Investors should watch the August 27th earnings report closely for signs that the custom chip momentum is translating into actual numbers.
Looking ahead
RBC's view is that Marvell is in a sweet spot, with multiple growth engines firing. The optical business is benefiting from the need for faster data transfer in AI data centers, while the custom chip deals provide a longer-term runway. The bank's expectation of a guidance raise suggests that management may be confident enough in the pipeline to signal stronger growth ahead.
Still, the market will be looking for more than just a beat. Investors will want to hear about the pace of custom chip ramps, the trajectory of optical sales, and how management plans to navigate the capacity crunch. Any commentary on these fronts could move the stock more than the headline numbers.
For now, RBC's analysis adds to the growing optimism around Marvell's AI prospects. But as with any high-flying tech stock, it's wise to remember that expectations are already high. A beat and a raise might be priced in, so the real test will be whether Marvell can exceed those raised expectations in the quarters to come.
