The pressure lands on Marvell's biggest bet. On November 2, Marvell agreed to buy Lumentum in an all-stock deal valued at $115 billion, or about $1,132 per Lumentum share. Each Lumentum share converts into 4.5 Marvell shares, and Marvell holders will own about 67% of the combined company. The deal targets more than $1 billion of annual cost savings and is expected to close in the first half of 2028.
The math has moved fast. At Friday's price, 4.5 Marvell shares are worth $691.20, about 18.0% above Lumentum's $585.67 quote at the same time. A spread that wide signals doubt about approvals or the long 2028 timeline. The $1,132 headline value implied a Marvell price of about $251.56, and the shares now sit 38.9% below it. The GuruFocus chart shows a GF Score of 84/100, a strong read built on a solid balance sheet with profitability that is only middling. GF Value is $128.22, so the shares still trade 19.8% above GuruFocus's estimate with a "Modestly Overvalued" label. The next test is the shareholder vote timeline and any regulatory filing on the merger.
