Credo Technology Group vs. Marvell Technology: Which Technology Stock Is a Better Buy for 2027?

As demand for artificial intelligence continues to reshape the global data landscape, investors are weighing the explosive growth of Credo Technology Group (NASDAQ:CRDO) against the established dominance of Marvell Technology (NASDAQ:MRVL).

Credo specializes in energy-efficient connectivity for high-speed networks, focusing on specific bottlenecks in hyperscale data centers. Marvell offers a more diverse range of semiconductor solutions covering storage, optical, and computing needs across the entire networking ecosystem. Comparing these two reveals a choice between a high-growth specialist and a diversified infrastructure giant.

The case for Credo Technology Group

Credo focuses on designing high-speed copper and optical interconnect solutions that facilitate massive data movements within cloud networks. The company primarily serves blue chip hyperscalers and equipment manufacturers, with high-profile partnerships including Oracle (NYSE:ORCL) and Microsoft (NASDAQ:MSFT). Customer concentration like this adds a layer of risk to the business, as nearly 90% of revenue in its latest annual report came from just 10 customers.

In the 12 months ended Aug. 1, 2026, revenue reached close to $1.6 billion, representing explosive growth of approximately 165.1% compared to the prior period. This rapid scaling helped the company generate a net income of roughly $538.3 million during that time frame. The resulting net margin of 33.8% highlights how effectively the company is translating its semiconductor stock sales into actual earnings as it expands.

As of its May 2026 balance sheet, the current ratio, which measures whether a company can cover its short-term debts with short-term assets, is 10.2x. The debt-to-equity ratio is 0.0x, indicating a balance sheet with no total debt relative to shareholder equity. In the fiscal year ended May 2, 2026, free cash flow was approximately $407.0 million. Note that stock-based compensation accounted for roughly 39.3% of operating cash flow, inflating reported cash generation, since SBC is a non-cash expense added back to cash flow in the cash flow statement.

The case for Marvell Technology

Marvell Technology provides the foundational hardware required to move, store, and process data across cloud and automotive markets. The company has a strong focus on the data center segment, which is increasingly driven by demand for custom silicon and high-speed networking. Marvell also maintains high customer concentration, as its top 10 customers accounted for roughly 82% of its revenue in its latest annual report.

In the 12 months ended Aug. 1, 2026, revenue was nearly $9.5 billion, representing revenue growth of approximately 30.6%. The company reported a net income of nearly $2.6 billion, which translates to a healthy net margin of 27.9%. While its growth is slower than its smaller rival, the sheer scale of its operations provides a broader footprint across the enterprise networking and carrier infrastructure industries.

As of its January 2026 balance sheet, Marvell has a debt-to-equity ratio of 0.3x, meaning it has roughly $0.30 in total debt per dollar of shareholder equity. Its current ratio is 2.0x, suggesting it maintains a comfortable buffer to meet its short-term obligations. In the fiscal year ended Jan. 31, 2026, free cash flow reached nearly $1.4 billion. Note that stock-based compensation accounted for roughly 33.8% of operating cash flow, inflating reported cash generation, since SBC is a non-cash expense added back to cash flow in the cash flow statement.

Risk profile comparison

Credo Technology Group faces significant revenue concentration risk due to its reliance on a small group of large customers that issue purchase orders rather than long-term commitments. The company faces intense competition from established giants like Broadcom (NASDAQ:AVGO) and newer entrants like Astera Labs (NASDAQ:ALAB). Geopolitical tensions between Taiwan and mainland China also pose supply chain vulnerabilities, while the cyclical nature of the chip market could lead to volatility in demand for high-speed connectivity products.

Marvell Technology faces substantial risks from customer concentration and the constant pressure to win design slots with major cloud providers. The company is managing a complex integration of its proposed $115 billion acquisition of Lumentum, which could strain financial resources if expected synergies do not materialize. Marvell also navigates a competitive landscape where large technology firms are increasingly designing their own custom chips, potentially reducing the total addressable market for third-party semiconductor providers.

Valuation comparison

Credo appears more attractive on a price-to-earnings basis, while Marvell trades at a slightly lower multiple relative to its trailing 12-month sales.

Which stock would I buy for 2027?

When comparing Credo and Marvell, investors should consider a few key factors. Let's have a look at them and see what that tells us about each stock.

Firstly, we should consider revenue growth. Both companies are delivering fantastic growth, but Credo can claim an advantage in the category. It has delivered average year-over-year revenue growth of 143% over the last three years. Marvell, meanwhile, has averaged 24% revenue growth.

Another factor to consider is each company's profitability. Again, Credo has an edge. Its operating margin stands at 32%, while Marvell's is 17%. That said, both companies have been consistently profitable for more than a year.

Finally, there's valuation. Given their profitability, we can examine each company's price-to-earnings (P/E) multiple. Once again, Credo comes out on top. Its 47x P/E multiple is ever so slightly more affordable than Marvell's 52x multiple.

To sum up, growth-oriented investors may want to consider both of these tech stocks. They both exhibit fantastic growth and solid profitability. That said, for me, Credo wins the head-to-head matchup given its stellar growth, better profitability, and more modest valuation.
