Marvell Reaches All Time Highs: Buy, Sell or Hold?

"Marvell is executing through one of the cleanest growth windows in semiconductors. Q3 FY2026 revenue hit a record $2.07 billion, up 37% YoY, with non-GAAP EPS of $0.76 versus $0.43 a year earlier. Data center revenue rose 38%, carrier infrastructure 98%, and enterprise networking 57%. With 50-plus custom AI design opportunities across 10-plus customers and three-nanometer wafer capacity locked in, multi-year revenue visibility is unusually strong."

"The Street's average price target sits at $130.28, implying roughly 24% downside from current levels. Marvell trades at a forward P/E of 43 and price-to-sales of 18. GuruFocus pegs the stock as 62.8% overvalued versus a $101.43 intrinsic value. Insider behavior reinforces caution with total insider sales reaching $26.2 million over three months with no buying activity."

Marvell Technology designs custom AI accelerators, optical interconnects, and networking silicon for hyperscale data centers, which generated 73% of Q3 FY2026 revenue. The stock surged from the high $70s in February to mid-$170s following a $2 billion NVIDIA investment, a custom chip engagement with Alphabet, and the Celestial AI acquisition. Q3 revenue reached a record $2.07 billion, up 37% year-over-year, with data center revenue rising 38% and carrier infrastructure up 98%. Q4 guidance projects $2.20 billion in revenue with full-year growth exceeding 40%. However, the stock trades at a forward P/E of 43 and price-to-sales of 18, with Street price targets averaging $130.28, implying 24% downside. Insider selling activity, including CEO disposals, raises valuation concerns despite strong multi-year revenue visibility from 50-plus custom AI design opportunities.
