Marvell agrees to absorb Lumentum in a $115 billion all-stock bet on optical AI links
· BehindLines newsroom · Updated
Chipmaker Marvell Technology announced on 2 November 2026 that it plans to acquire Lumentum Holdings, a specialist in optical components, in a deal paid entirely in shares. According to the two companies' joint announcement, the enterprise value comes to $115 billion. Yahoo Finance article; release filed with the SEC.
The terms of the deal
According to the release, each Lumentum share will be exchanged for 4.5 Marvell shares, apart from cash paid for fractional shares. That works out to about $1,132 per Lumentum share, a premium of roughly 23.9% to the 28 October prices, a price described as unaffected by the deal. Once the deal closes, Marvell shareholders would own about 67% of the group and Lumentum shareholders about 33%, on a fully diluted basis. Both boards approved the agreement unanimously.
Nothing is settled yet. The release expects completion in the first half of 2028, subject to a vote by the shareholders of both companies, regulatory approvals and customary conditions. According to the text, Matt Murphy would remain chairman and chief executive of the group, and three Lumentum directors, including its chief executive Michael Hurlston, would join Marvell's board, which currently has seven members. The release does not specify the future headquarters and mentions no termination fee.
Why optics
Marvell designs high-speed connection chips and custom processors for data centers; Lumentum makes lasers, optical transceivers and optical switches. Both companies argue that sending data as light is becoming decisive in the computing clusters built for artificial intelligence, where huge volumes of information must move between processors, servers and distant sites. According to Yahoo Finance, optical technology and manufacturing capacity have become bottlenecks in building AI infrastructure, and the deal would give Marvell better access to both.
Matt Murphy says AI infrastructure is going through "a fundamental architectural shift toward optical connectivity." Michael Hurlston says the union puts the combined company in a unique position to address a $550 billion market. That figure, which describes the potential market of the future group, comes from the two companies and was not independently validated by Yahoo Finance.
The promised synergies
The release also highlights Lumentum's compound-semiconductor manufacturing, notably based on indium phosphide, a key material for lasers. The two groups announce more than $1 billion in annual cost savings, better margins and a boost to Marvell's adjusted earnings per share in the first year after closing. These are management targets, not results already achieved.
A value linked to Marvell's share price
The consideration is a fixed number of Marvell shares. Its dollar value therefore changes with Marvell's share price.
