Marvell Technology has signed a definitive agreement to buy Lumentum in an all-stock deal that values the laser and optics company at around $115 billion, the two companies announced on November 2, 2026. Lumentum shareholders will receive 4.5 Marvell shares for each share they hold, equivalent to about $1,132 per share and a premium of roughly 23.9%. The deal isn’t expected to close until the first half of 2028.
Marvell’s purchase of Lumentum, in 30 seconds
- All-stock deal: 4.5 Marvell shares for every Lumentum share, with an implied enterprise value of $115 billion.
- Marvell shareholders will own about 67% of the combined company, and Lumentum shareholders the remaining 33%.
- The companies promise more than $1 billion a year in cost synergies.
- Closing depends on shareholders and regulators, and is expected in the first half of 2028.
The announcement confirms what the market had anticipated since late October, when news of the talks between Marvell and Lumentum first emerged. The premium is calculated on the closing price from October 28, the last trading day before the speculation began. Both boards approved the deal unanimously.
Why Marvell wants Lumentum’s lasers
The logic behind the deal is the shift from copper to optics in AI data centers. As clusters grow, electrical connections fall short on distance, bandwidth, and power consumption, and the industry is moving toward increasingly integrated optical solutions that require designing the electrical and optical sides together.
Marvell brings electrical and optical interconnect, network switching, custom chips (XPUs), and advanced semiconductor technology. Lumentum adds high-performance lasers, optical transceivers, optical circuit switching (OCS), and, above all, its own compound-semiconductor manufacturing, including indium phosphide (InP), a key material for communications lasers. The companies describe it as “extreme co-design”: designing the entire signal path together, from distributed data centers down to the connections inside the chip package itself.
Matt Murphy, Marvell’s chairman and CEO, says in the companies’ statement that AI infrastructure is undergoing an architectural shift toward optical connectivity that comes “once in a generation.” Michael Hurlston, Lumentum’s CEO, argues the combination will let the companies meet the full range of customer interconnect needs, from today’s data-center-to-data-center networks to the scale-up domains inside the rack that are coming next.
The numbers the companies are promising
According to the joint statement, the deal will expand the combined company’s total addressable market (TAM) to $550 billion, deliver more than $1 billion a year in cost synergies, and be accretive to Marvell’s adjusted earnings per share from the first year after closing. These are the companies’ own estimates: total addressable market isn’t a sales figure, and the statement doesn’t detail how it’s calculated or over what timeframe the synergies would be achieved.
After closing, Murphy will remain chairman and CEO. Three Lumentum directors, including Hurlston, will join Marvell’s board, which currently has seven members. Marvell also reported preliminary revenue for its fiscal 2027 third quarter, in line with expectations: it’s holding the midpoint of its range and narrowing it to a margin of roughly plus or minus 2%, down from 5% initially. These figures are unaudited.
A distant close, subject to regulators
The timeline is long. The companies don’t expect to close the deal until the first half of 2028, pending the vote of both companies’ shareholders, regulatory approvals, and other customary conditions. The statement doesn’t specify which countries will need to sign off, but deals of this size in semiconductors typically draw scrutiny from competition authorities in the United States, the European Union, and China, among others.
Meanwhile, demand for optical components keeps straining the supply chain. Cloud News has already reported how Marvell itself raised its 2028 revenue forecast to $20 billion on the back of AI-driven data center growth, and Tower Semiconductor is investing $4 billion in Japan to build optical chips for AI. The Lumentum purchase is precisely about locking in laser manufacturing capacity in a market where it’s running short.
