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

As demand for artificial intelligence accelerates, investors are weighing the merits of Arm (NASDAQ:ARM) and Credo Technology Group (NASDAQ:CRDO). Choosing between them requires deciding which business model is the better buy.

Arm provides the essential blueprints for modern processors, while Credo focuses on the high-speed connections that allow those processors to talk to each other. Both companies are vital to the data center infrastructure that powers the modern web, making them popular choices for investors seeking exposure to the semiconductor industry.

The case for Arm

Arm designs and licenses the fundamental architecture used in nearly every smartphone on the planet. In its latest annual report, filed for the fiscal year ended March 31, 2026, the company highlights its position among semiconductor stocks, generating royalties from chipmakers in various sectors. This asset-light model allows the business to reach end markets like data centers and vehicles without the heavy costs of manufacturing hardware.

In FY 2026, revenue reached nearly $4.9 billion, representing growth of approximately 22.8% compared to the prior year. The company reported net income of roughly $904.0 million during this same period. While revenue increased, the net margin, which measures the percentage of revenue remaining as profit after all expenses, decreased slightly to about 18.4% from 19.8% in the previous fiscal year.

As of its March 2026 balance sheet, the company maintained a debt-to-equity ratio of nearly 0.1x, indicating very little debt relative to shareholder equity. The current ratio was approximately 6.0x, which measures the company's ability to cover its short-term debts with short-term assets. Note that stock-based compensation represented roughly 69% 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 Credo Technology Group

Credo Technology Group focuses on high-speed connectivity solutions that move data quickly and efficiently between servers. In its latest annual report, filed for the fiscal year ended May 2, 2026, the company highlights its work with cloud giants like Oracle (NYSE:ORCL) and Microsoft (NASDAQ:MSFT). Since its top 10 customers account for approximately 90% of total revenue, this concentration adds a significant layer of risk to the business.

In FY 2026, the company saw revenue surge to nearly $1.3 billion, which represents a massive growth rate of roughly 205.7% year-over-year. Net income for the period was approximately $472.3 million. The net margin expanded significantly to close to 35.4% during the period, up from roughly 11.9% in the prior fiscal year.

As of its May 2026 balance sheet, the debt-to-equity ratio was nearly 0.0x. The current ratio was approximately 10.2x, while free cash flow reached nearly $407.0 million during the fiscal year. 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.

Risk profile comparison

Arm faces risks related to the competitive landscape of chip architecture and shifting geopolitical trade policies. The company must continuously innovate to ensure that its designs remain the standard as competitors develop alternative open-source architectures. Because its technology is used globally, any changes in international trade regulations could impact its ability to license intellectual property to certain regions.

Credo Technology Group is highly dependent on a small number of customers, including Oracle and Microsoft. The business also relies exclusively on Taiwan Semiconductor Manufacturing for wafer production, which creates vulnerability to supply chain disruptions or geopolitical tensions. Furthermore, the company faces intense competition from Broadcom (NASDAQ:AVGO) and Marvell Technology (NASDAQ:MRVL) in the rapidly changing market for high-speed connectivity.

Valuation comparison

Credo Technology Group looks cheaper than Arm because it trades at a much lower multiple of its future earnings estimates and sales.

Which stock would I buy in 2026?

I'd go with Credo Technology, though Arm Holdings is a harder company to walk away from than its premium valuation implies. Arm's chip architecture is embedded in virtually every smartphone and increasingly in AI data centers. Royalty revenue more than doubled in the data center segment and the business compounds reliably regardless of any single customer relationship. For a long-term investor who values durability and consistency, it is a strong choice.

But Credo just delivered some spectacular results: its seventh consecutive quarter of triple-digit year-over-year revenue growth, exceeding the high end of its own guidance and posting nearly 50% net margins. Its connectivity chips and optical products are becoming essential infrastructure inside the AI data centers being built by every major hyperscaler, and management guided for more than 85% revenue growth for the full year.

Customer concentration is the one risk worth watching closely. But for a long-term investor comfortable with that trade-off, Credo's growth trajectory is one of the most impressive in semiconductors right now.
