Marvell to acquire Lumentum for $115B in all-stock AI connectivity deal

Investors dumped both stocks immediately, signaling skepticism that bundling optics and silicon will pay off.

• Marvell will acquire Lumentum in an all-stock deal carrying an implied enterprise value of $115 billion, with Lumentum holders getting 4.5 Marvell shares for each share they own.
• Lumentum makes high-performance lasers, optical transceivers and optical circuit switches used to connect chips and systems inside AI data centers.
• The exchange ratio implies about $1,132 per Lumentum share, a roughly 23.9% premium over its unaffected price before deal rumors surfaced on October 28.
• Marvell shareholders will own about 67% of the combined company after close, with Lumentum shareholders holding the remaining 33%.
• The companies expect more than $1 billion in annual run-rate cost synergies and project the combined firm's addressable market will grow to $550 billion.
• Marvell shares slumped about 13% and Lumentum fell nearly 19% on the announcement, a sign markets are wary of an all-stock megadeal with no cash cushion.
• Nvidia had already taken a $2 billion stake in Lumentum earlier in 2026, underscoring how central optical connectivity has become to AI chip buildouts.
• The tie-up ranks among the largest tech deals ever and signals that AI infrastructure competition is shifting from pure silicon toward integrated electrical-optical systems.
