Marvell Technology (NASDAQ:MRVL) shares climbed 12.22% at 11 a.m. ET on Wednesday, November 11, in regular trading, as CoreWeave’s results revived AI connectivity names. TheStreet listed Marvell among the morning’s top gainers alongside Lumentum, Sandisk and Seagate.

Marvell agreed on November 2 to acquire Lumentum for 4.5 Marvell shares per Lumentum share, an enterprise value of $115 billion. Marvell holders would own about 67% of the combined company, and management sees more than $1 billion in annual run-rate cost synergies, with closing expected in the first half of 2028. Optics & Photonics News reportedciting Reuters, that Marvell fell more than 10% after the announcement.

Ceding a third of the company means the deal works only if optical revenue grows faster than Marvell’s own base. The $1 billion synergy target equals under 1% of the deal’s enterprise value per year, so revenue synergies must do the heavy lifting. GuruFocus gives Marvell a GF Score of 84/100, with Financial Strength 7/10, Momentum Rank 6/10, Profitability Rank 5/10 and GF Value Rank 5/10. At $164.41, the shares trade 28.5% above GuruFocus’s GF Value of $127.94, which GuruFocus labels “Modestly Overvalued.” Regulatory review is the next hurdle.
