“AI infrastructure is undergoing a fundamental architectural shift toward optical connectivity, creating an opportunity that comes along once in a generation,”
Matt Murphy, chairman and CEO of Marvell
Marvell’s proposed acquisition of Lumentum would join a supplier of data-center chips and interconnect technology with a maker of lasers, optical transceivers and optical switches. The companies announced the agreement on November 2, 2026, according to Marvell’s filing. The filing lists November 1 as the date of the earliest event reported, but does not state that the agreement was entered into that day. The all-stock transaction assigns Lumentum an implied enterprise value of $115 billion.
4.5 Marvell shares for each Lumentum share
Under the agreement, Lumentum shareholders would receive 4.5 shares of Marvell common stock for each Lumentum common share. The companies put the implied value at about $1,132 per Lumentum share, a 23.9% premium to the companies’ unaffected closing share prices on October 28—the last trading day before speculation about a potential deal began.
After the merger, Marvell shareholders would own about 67% of the combined company on a fully diluted basis and Lumentum shareholders about 33%. The companies’ boards unanimously approved the agreement. Marvell CEO Matt Murphy is set to remain chairman and CEO; three Lumentum directors, including its CEO, Michael Hurlston, are expected to join Marvell’s board.
Chips, lasers and optical switches under one roof
Marvell brings electrical and optical interconnects, network switching, custom silicon and advanced semiconductor technologies. Lumentum adds high-performance lasers, optical transceivers, optical circuit switching and specialized compound-semiconductor manufacturing. The companies say the combined portfolio could connect systems across distances ranging from distributed data centers to links within advanced semiconductor packages.
The strategic case rests on shifting more data-center connections from copper toward optical technologies as bandwidth demands rise. The companies argue that integrating electrical and optical design could improve bandwidth, performance and power efficiency, while allowing customers to develop and deploy systems faster. Those are the parties’ expectations for the combination, not results demonstrated by the proposed merger.
$550 billion market estimate, with more than $1 billion in projected savings
Marvell and Lumentum estimate that the combined company would address a $550 billion total market. They also project more than $1 billion in annual run-rate cost synergies and say the deal should increase Marvell’s non-GAAP earnings per share in the first year after closing. The filing does not present those projections as realized savings or earnings gains.
The scale of the deal reflects Marvell’s bet that optical connections will become more central as AI systems grow and their networks become more complex. The transaction would give the company a broader set of components and manufacturing capabilities to sell and integrate, but it also ties the thesis to a long path through shareholder votes and regulatory review.
Closing is not expected before 2028
The companies expect the deal to close in the first half of calendar year 2028, subject to approval from both companies’ shareholders, regulatory approvals and other customary closing conditions. Until then, the $115 billion figure describes the proposed transaction’s implied enterprise value; the consideration for Lumentum common shareholders is Marvell stock, at the fixed 4.5-to-1 exchange ratio.
