The Motley Fool author leans toward Astera Labs for faster growth and potential AI-data-center upside, but says its reliance on a few customers makes it riskier; Marvell Technology has broader operations and lower valuation multiples.
Astera reported $852.5 million in 2025 revenue, up 115%; one customer accounted for more than 70%, and its top three about 86%. Marvell reported nearly $8.2 billion in revenue for the fiscal year ended Jan. 31, 2026, up about 42%; its 10 largest customers accounted for roughly 82%. The article cites forward P/E ratios of 89.8 for Astera and 60.9 for Marvell, and price-to-sales ratios of 51.2 and 23.7, respectively; it notes valuation figures may vary by provider.
Analysts cited in the article project annualized revenue growth over the next two years of 87% for Astera and 49% for Marvell. The author says Astera’s potential upside depends on continued rapid AI data-center growth. Astera also relies on a sole-source manufacturer, Taiwan Semiconductor Manufacturing, and has East Asia exposure; Marvell faces risks from customers developing their own chips, patent litigation and changing export controls.
