CRDO vs. MRVL: Which Connectivity Stock Has More Upside in the AI Era?

The article compares Credo Technology Group (CRDO) and Marvell Technology (MRVL), both critical semiconductor providers for AI-driven data centers, highlighting CRDO as a stronger current investment. CRDO is experiencing robust growth fueled by its AEC business, optical DSPs, and increasing hyperscaler adoption, projecting approximately 120% year-over-year revenue growth and a 40% non-GAAP net margin for fiscal 2026, contributing to a 76% stock surge in three months and a Zacks #1 (Strong Buy) rank. In contrast, MRVL's data center revenues surged 69% year-over-year to $1.49 billion in fiscal Q2 2026, driven by custom silicon and electro-optics, with a strategic aim to capture 20% of a $94 billion data center TAM by 2028, though its stock declined 1.7% over the same period, holding a Zacks #3 (Hold) rank.

Analysis

Credo Technology (CRDO) and Marvell Technology (MRVL) are both key semiconductor suppliers for AI data center infrastructure, but they currently present divergent investment profiles. CRDO is exhibiting hyper-growth characteristics, underscored by a projected 120% year-over-year revenue increase for fiscal 2026 and a strong 40% non-GAAP net margin target. This is driven by accelerating demand for its Active Electrical Cables (AECs), which offer 50% lower power consumption than alternatives, and a rapidly expanding hyperscaler customer base. The market has rewarded this momentum, with CRDO's stock surging 76% in three months, supported by significant upward earnings estimate revisions and a Zacks #1 'Strong Buy' rank. In contrast, Marvell, a more established player, reported a solid 69% year-over-year increase in its data center revenue to $1.49 billion but has guided for flat segment revenue in the current quarter due to a temporary dip in custom silicon orders. While MRVL has a robust long-term plan to capture 20% of a $94 billion TAM by 2028, it faces headwinds from US-China trade tensions, heavy leverage, and a stock that has declined 1.7% over the same three-month period. This performance disparity is reflected in valuations, with CRDO trading at a premium forward price-to-sales ratio of 26.94x compared to MRVL's 7.17x, indicating investors are pricing in CRDO's superior near-term growth trajectory.

Key Decisions for Investors

• Investors prioritizing near-term growth may favor Credo Technology (CRDO), given its projected 120% revenue growth and strong momentum with hyperscalers, but must be comfortable with its premium valuation at a 26.94x forward P/S ratio.
• For Marvell Technology (MRVL), investors should monitor for a rebound in custom silicon revenues in the fourth quarter and any shifts in US-China trade relations, as the stock's lower 7.17x P/S ratio could present a relative value opportunity if near-term headwinds subside.
• Given the stark divergence in stock performance, with CRDO up 76% and MRVL down 1.7% in three months, a relative value strategy or pairs trade could be considered, favoring CRDO for its current growth momentum and positive analyst sentiment.
• Closely watch CRDO's ability to maintain its projected 40% non-GAAP net margin and its progress in ramping up its two additional hyperscaler clients in fiscal 2026, as these are critical to justifying its current valuation.
