Credo Technology Group vs. Marvell Technology: Which Stock Is a Better Buy in 2026?

As artificial intelligence pushes the limits of connectivity, Credo Technology Group (NASDAQ:CRDO) and Marvell Technology (NASDAQ:MRVL) are racing to build the high-speed pathways that define the modern data center.

Credo targets energy-efficient, niche connectivity solutions, whereas Marvell operates as a broad-scale provider of networking and storage components. Both companies are central to the infrastructure transition occurring in cloud computing. Investors must weigh Credo's hyper-growth potential against the established reliability and diverse product lineup of Marvell to decide which fits their strategy.

The case for Credo Technology Group

Credo Technology Group designs high-speed copper and optical connectivity products specifically for data infrastructure. It focuses on the hardware that moves data quickly between servers, a critical need for cloud providers. Major commercial relationships include collaborations with Microsoft for network-managed architectures and Oracle for transceiver development. Customer concentration like this adds a layer of risk to the business, as the top 10 clients represent roughly 90% of total revenue.

In the fiscal year ended May 2, 2026, revenue reached nearly $1.3 billion, representing a significant revenue growth of approximately 205.7% over the prior year. The company reported a net income of close to $472.3 million. This marks a sharp improvement from the net loss recorded just two years prior, reflecting a rapid scale-up in its core markets.

As of its May 2026 balance sheet, the debt-to-equity ratio is 0.0x, meaning the company carries no total debt relative to its shareholder equity. The current ratio, which measures the ability to pay short-term debts with current assets, is roughly 10.2x. Free cash flow, or the cash left after capital spending, reached close to $407.0 million. Note that stock-based compensation represented roughly 39.3% of operating cash flow, which inflates reported cash generation since SBC is a non-cash expense added back in the cash flow statement.

The case for Marvell Technology

Marvell Technology supplies data infrastructure solutions that span from the data center core to the network edge. It recently divested its automotive ethernet business to focus on AI infrastructure, custom silicon, and high-speed data center networking. One direct customer and one distributor account for about 14% and 37% of revenue, respectively, reflecting its presence across the broader tech supply chain.

In FY 2026, revenue reached approximately $8.2 billion, up by nearly 42.1% compared to the previous fiscal year. The company generated a net income of roughly $2.7 billion. This was a notable turnaround from the net loss reported in its latest annual report filed for the previous period ending in early 2025.

Based on its January 2026 balance sheet, the debt-to-equity ratio is approximately 0.3x. This ratio shows that for every dollar of equity, the company has about 30 cents in total debt. The current ratio is close to 2.0x, while free cash flow reached nearly $1.4 billion. Note that stock-based compensation represented roughly 33.8% of operating cash flow, which inflates reported cash generation since SBC is a non-cash expense added back in the cash flow statement.

Risk profile comparison

Credo Technology Group faces risks from heavy revenue concentration and a lack of long-term purchase commitments. It competes directly with larger, established firms like Broadcom (NASDAQ:AVGO), Marvell Technology, and Astera Labs (NASDAQ:ALAB). Supply chain dependence on third-party foundries like TSMC in Taiwan also creates geopolitical vulnerability for its primary operations.

Marvell Technology is challenged by significant customer concentration and high debt levels compared to smaller peers. It must also manage the complex integration of recent acquisitions while competing with giants such as Nvidia (NASDAQ:NVDA), Broadcom, and Intel (NASDAQ:INTC). Regulatory restrictions on sales to certain regions like China also represent a headwind for long-term growth.

Valuation comparison

Marvell Technology appears more expensive based on Forward P/E, which compares price to future earnings estimates, though both companies trade at high multiples relative to revenue.

Valuation metrics include sourcing from Financial Modeling Prep (FMP) and may differ from other data providers.

The P/S ratio, which measures price relative to sales over the past twelve months, shows that both companies are valued similarly on a revenue basis despite their different growth profiles.

Which stock would I buy in 2026?

I'd go with Credo Technology. Its connectivity chips are becoming essential inside the AI data centers being built by every major hyperscaler, and the numbers are backing it up. The company has strung together one of the most impressive growth streaks in the semiconductor industry, with revenue approaching or exceeding triple digits for several consecutive quarters. Its gross margins are near 70%, and guidance points to more than 85% revenue growth for the full year.

Marvell is certainly no slouch here. Its most recent quarter set a revenue record, and the company guided for accelerating growth through the rest of the year. And its strategic investment from Nvidia adds a new layer of credibility. For investors who value scale and a more diversified customer base, Marvell is a strong choice.

Customer concentration is the main risk with Credo, since a handful of hyperscalers drive most of its revenue. But the demand behind those relationships keeps growing, and the results keep arriving ahead of expectations. For an investor comfortable with that trade-off, Credo's growth trajectory is simply in a different league right now.
