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

As data centers evolve to meet the needs of artificial intelligence, investors are closely weighing the potential of Credo Technology Group (NASDAQ:CRDO) and Sandisk (NASDAQ:SNDK). Which of these hardware players is the better buy for your portfolio?

Credo specializes in high-speed connectivity solutions that enable rapid data transfer in complex networks, while Sandisk is a leader in NAND flash memory storage. Both companies are essential to modern digital infrastructure, but they operate at different scales and valuation levels. This comparison looks at their growth, financial health, and risks to help you decide.

The case for Credo Technology Group

Credo sells high-speed copper and optical interconnect solutions. These components help move data quickly within the world of semiconductor stocks. In its latest annual report, filed for the period ending May 2, 2026, the company highlighted its work with Oracle (NYSE:ORCL) and Microsoft (NASDAQ:MSFT) to build reliable cable architectures. Customer concentration like this adds a layer of risk to the business, as a small number of buyers drive most sales.

In FY 2026, revenue reached nearly $1.3 billion, representing growth of approximately 205.7% over the prior year. This surge moved the company into the black, delivering net income of roughly $472.3 million. This performance compares favorably to the previous year, when net income was closer to $52.2 million.

As of its May 2026 balance sheet, the debt-to-equity ratio is 0.0x, showing the company has no debt relative to shareholder equity. Its current ratio, which measures the ability to cover short-term bills with assets that can be quickly turned into cash, is 10.2x. Free cash flow, the cash a business generates after paying for capital expenditures, reached $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 Sandisk

Sandisk focuses on NAND flash memory, which provides the storage needed for data centers, mobile devices, and PCs. The company manufactures solid-state drives and embedded products for cloud service providers and major hardware manufacturers. In its latest annual report, filed for the fiscal year ended June 2025, it highlighted its use of long-term engagement frameworks to secure business. It also maintains a presence in China through the Unis Venture.

In FY 2026, revenue reached close to $20.2 billion, reflecting a growth rate of roughly 175.3%. The company turned a significant corner, reporting net income of nearly $11.4 billion for the period. This represents a massive swing from the net loss of $1.6 billion recorded in the prior fiscal year.

As of its July 2026 balance sheet, the debt-to-equity ratio is 0.0x, meaning the company carries no debt compared to its shareholder equity. The current ratio is 2.3x, indicating a healthy ability to cover upcoming financial obligations. Free cash flow for the year was approximately $11.5 billion. Because stock-based compensation was only about 2% of cash flow from operations, it does not significantly impact the quality of reported cash flow.

Risk profile comparison

Credo faces intense competition from larger semiconductor companies like Broadcom (NASDAQ:AVGO) and Marvell Technology (NASDAQ:MRVL). The business depends heavily on a small group of customers, with 90% of fiscal 2026 revenue coming from its top 10 clients. Furthermore, it relies exclusively on Taiwan Semiconductor Manufacturing Company for its chips. Geopolitical tensions involving Taiwan could disrupt its entire supply chain.

Sandisk relies on joint ventures with Kioxia for its entire supply of flash memory. The industry is known for its cyclicality, meaning prices for storage can drop rapidly when there is too much supply. It competes with global giants like Samsung Electronics (OTC:SSNLF), SK Hynix (NASDAQ:SKHY), and Micron Technology (NASDAQ:MU). Additionally, its recent separation from Western Digital (NASDAQ:WDC) involves complex legal and operational transitions that could create liabilities.

Valuation comparison

Sandisk currently trades at a significantly lower Forward P/E based on future earnings estimates, suggesting it may be the more value-oriented choice today.

Which stock would I buy in 2026?

I'd go with Credo Technology, though Sandisk's transformation into a contracted AI infrastructure play makes this a closer call than it might appear. Sandisk has locked in multi-year pricing agreements with major hyperscalers, covering the majority of its capacity through 2028 and backed by billions in customer financial guarantees. Wall Street is starting to value it less like a commodity memory maker and more like a predictable infrastructure company.

That said, Credo is doing something difficult to find anywhere in semiconductors right now. The company has strung together one of the most impressive growth streaks in the industry, with revenue approaching or exceeding triple digits for several consecutive quarters, gross margins near 70%, and guidance pointing to more than 85% revenue growth for the full year.

Customer concentration is the one risk that deserves attention. But the demand behind those relationships keeps accelerating. For investors with a long time horizon, that momentum is the stronger bet.
