- Marvell has agreed to buy Lumentum in an all-stock deal valued at about $115 billion, announced on November 2, 2026 and one of the largest tech mergers ever announced.
- Lumentum holders get 4.500 Marvell shares per share (about $1,132, a 23.9% premium); Marvell owners will hold about 67% of the combined company, with closing expected in the first half of 2028 pending shareholder and regulator approval.
- The deal pairs Marvell's data-moving chips with Lumentum's lasers and optical gear as AI data centers shift from copper to optical links, with more than $1 billion in yearly savings targeted.
- Marvell — chipmaker behind interconnect chips, DSPs, custom AI accelerators and Ethernet switches; the acquirer
- Lumentum — maker of lasers, optical transceivers and optical circuit switching gear; the acquisition target
Two big chip companies are joining forces for the AI age. Marvell has agreed to buy Lumentum in a huge deal. The Marvell-Lumentum deal is worth about $115 billion. It is one of the largest tech mergers ever announced.
The companies shared the news on November 2, 2026. The goal is to lead in AI connectivity. In other words, they want to move data faster inside AI data centers. Additionally, both boards have already approved the plan.
What does the deal include?
This is an all-stock deal, not a cash purchase. Marvell will pay Lumentum owners with its own shares. The main terms are simple to follow. The points below lay them out.
- Implied value of about $115 billion for Lumentum
- That works out to roughly $1,132 per Lumentum share
- A premium of about 23.9% over the October 28 price
- Exchange ratio of 4.500 Marvell shares per Lumentum share
- Marvell owners will hold about 67% after the deal
Lumentum shareholders will own the other 33%. The deal is expected to close in the first half of 2028. However, it still needs shareholder and regulator approval. Therefore, the timeline could still shift.
Why This Deal Matters for AI
AI data centers move massive amounts of data every second. The wiring that carries that data is now a problem. The sections below explain the shift driving this deal.
The Limits of Copper
For years, data centers used copper wiring to link chips. Copper works well, but it has clear limits. It struggles to carry huge data loads over distance. As a result, it can slow down large AI systems.
AI needs far more bandwidth than copper can give. That is pushing the industry toward light-based links. In other words, optics are replacing copper inside data centers. This is the core idea behind AI connectivity.
What Each Company Brings
Marvell makes chips that move and manage data. These include interconnect chips, DSPs, and custom AI accelerators. It also builds Ethernet switches for networks. In short, Marvell handles the electronic side of data movement.
Lumentum brings the optical side to the table. It makes lasers, optical transceivers, and optical circuit switching gear. These parts send data as light instead of electricity. Consequently, the two firms fit together neatly.
| Detail | Figure |
|---|---|
| Deal value | About $115 billion (all stock) |
| Price per Lumentum share | About $1,132 |
| Premium | About 23.9% |
| Exchange ratio | 4.500 Marvell shares per share |
| Expected close | First half of 2028 |
| Combined market size | About $550 billion |
The Leaders and the Savings
Matt Murphy will stay as Chairman and CEO of Marvell. Lumentum CEO Michael Hurlston will join Marvell’s board. Two other Lumentum directors will join him. This keeps optical expertise close to the top.
The companies also expect large cost savings. They target more than $1 billion in yearly savings. Additionally, they expect the deal to lift non-GAAP earnings quickly. The combined market is valued at about $550 billion.
Ripples Across the Tech Supply Chain
This deal shows where AI spending is heading next. Chips still matter, but moving data now matters just as much. Buyers of networking and optical parts should take note. Demand for these components is clearly rising.
Finding reliable suppliers is a growing challenge for firms. A global B2B marketplace helps buyers source chips and optical parts worldwide. Such platforms connect buyers with trusted, verified sellers. That reach matters as AI hardware demand grows.
This story fits a wider AI hardware boom. B2BInside covered how the AI data center boom caused a global memory chip shortage. Chipmakers are racing to build faster AI parts too. Our report on how Alibaba introduced a new AI chip shows that push.
Will the Deal Go Through?
The plan has strong backing from both boards. Still, big deals face close review by regulators. A deal this large will draw real scrutiny. Approval could take many months.
Ultimately, the Marvell Lumentum deal is a bet on optics. It assumes AI data centers will keep growing fast. For now, the two firms are preparing to combine. Buyers and rivals will watch the outcome closely.
