Marvell Lumentum Deal: $115B All-Stock Buy at About $1,132 a Share

Marvell Technology signed a definitive agreement on Nov. 2 to acquire Lumentum in an all-stock deal with an implied enterprise value of $115 billion, paying 4.500 Marvell shares for each Lumentum share, the companies said in a joint release.

The exchange ratio works out to about $1,132 per Lumentum share, a premium of roughly 23.9% to the Oct. 28 closing prices, the last trading day before market speculation began. Both boards approved the deal unanimously. Marvell holders will own about 67% of the combined company on a fully diluted basis and Lumentum holders about 33%. Reuters, which put the deal at $115 billion including debt, reported an equity value of $102.54 billion.

Marvell Lumentum Deal Terms vs. the Reported Talks

Bloomberg first reported Marvell's talks on Oct. 28, as Voltgrid reported on Oct. 29, and no price, premium or cash-versus-stock split was known. The $83 billion figure in that story was Lumentum's market value, per TrendForce, not an offer. The signed terms replace it with a price, a premium and a structure: no cash component, and a fixed ratio, so the dollar value moves with Marvell's share price until closing. With no cash component, the deal needs no cash payment to Lumentum holders, which answers the question Bernstein analysts raised about Marvell's roughly $3.92 billion in cash and equivalents at its latest quarter.

Reuters reported that Marvell shares were up 2.8% in premarket trading on Nov. 2 and that trading in Lumentum was halted. Since the talks were first reported, it said, Lumentum shares had fallen about 8% and Marvell about 22% in a broad chip selloff after Intel's weak forecast.

Why Lasers Matter for AI Interconnect

An optical link needs a laser to make the light and electrical chips to drive and read it. Marvell's release says the physical limits of copper are pushing AI infrastructure toward optical connections, and that scale-up links inside a cluster need closer co-design of the electrical and optical parts. Marvell supplies the electrical side. Lumentum supplies lasers, optical transceivers and optical circuit switches.

Lumentum reported $1.26 billion of revenue for the quarter ended Sept. 26, 2026, up from $533.8 million a year earlier, and said a second major NPO/CPO win carries purchase commitments above $5 billion. Marvell claims that designing both halves together will raise bandwidth and power efficiency. That is a company claim, and neither company gave a power figure, so the effect on watts per bit is unproven until products ship.

The companies also put the combined addressable market at $550 billion and said the deal gives line of sight to more than $1 billion in annual run-rate cost synergies, with accretion to Marvell non-GAAP earnings per share in year one after closing.

Board, Closing Timeline and Open Questions

Matt Murphy stays chairman and CEO. Three Lumentum directors, including CEO Michael Hurlston, would join Marvell's board, which has seven directors today. The deal is expected to close in the first half of calendar 2028, subject to approval by both companies' stockholders, regulatory approvals and other customary conditions. Reuters called it Marvell's largest purchase since its $10 billion Inphi deal in 2021, following a $3.5 billion Celestial AI purchase that closed in February.

Closing is expected in the first half of 2028, more than a year away, and depends on regulators. Reuters said NVIDIA invested $2 billion each in Marvell and Lumentum earlier this year; neither the release nor Reuters says how those stakes will be treated, or how NVIDIA's March 2 multibillion purchase commitment and capacity access rights for Lumentum lasers are affected. Antitrust review has not been described by either company.
