Two companies whose names rarely appear in everyday conversation are now at the centre of one of the largest takeovers the technology industry has ever seen. Marvell Technology, an American chip designer, has agreed to buy Lumentum, a specialist in optical components and networking equipment, in a transaction valued at around 115 billion dollars once debt is included.
The scale becomes clearer against earlier landmark purchases. Microsoft paid 68.7 billion dollars for the gaming group Activision Blizzard, while Dell spent 67 billion dollars on the storage company EMC. Marvell’s agreement is larger than both. Their work sits deep inside the infrastructure that powers cloud services and artificial intelligence.
What Marvell and Lumentum Actually Make
Marvell designs specialised semiconductors used in data centres, networking hardware and systems built for artificial intelligence. Its chips help to shift and process the enormous volumes of information that cloud platforms and AI applications depend on every day.
Lumentum works in a related but different field. It builds optical technology, including lasers and parts that send information using light rather than electrical signals travelling through copper wire. Copper connections struggle when huge amounts of data must travel over longer distances, and they consume more power. Optical links can move information very quickly while using energy more efficiently.
By bringing these two sets of skills under one roof, Marvell and Lumentum hope to build faster and more efficient connections for the data centres of the future. One company understands how to process and route data, the other understands how to transmit it at speed through light.
The Terms of the $115 Billion Deal
The agreement, announced on 2 November, is structured as an all-stock transaction, meaning Marvell will pay for Lumentum with its own shares rather than cash. Each Lumentum share will be exchanged for 4.5 Marvell shares. When the deal closes, existing Marvell shareholders are expected to hold roughly 67 per cent of the combined business, while Lumentum shareholders will own the remaining 33 per cent.
Leadership has also been settled in advance. Marvell’s chairman and chief executive, Matt Murphy, will continue to run the combined group. Three directors from Lumentum’s board, including its chief executive Michael Hurlston, will join Marvell’s board, giving the acquired company’s leadership a direct voice in the new organisation.
Completion is not expected immediately. The companies anticipate that the transaction will close during the first half of 2028, and only after both sets of shareholders and the relevant regulators have given approval.
Nvidia’s $4 Billion Stake in Both Companies
One revealing detail is the involvement of Nvidia, the chipmaker whose processors have become central to the AI industry. In March 2026, Nvidia announced a 2 billion dollar investment in Lumentum, tied to a partnership aimed at developing advanced optical technology, supporting research, larger manufacturing capacity and laser components for AI infrastructure.
Later in the same month, Nvidia announced a separate 2 billion dollar investment in Marvell, centred on improving connections inside AI infrastructure, including optical networking and semiconductor technology. Taken together, the two investments amount to 4 billion dollars, so Nvidia had already placed substantial bets on both sides of this takeover months before it was announced.
Those partnerships underline a broader shift in the AI race. Attention has long focused on the processors that train and run AI models, but the networks linking those processors together are becoming a decisive factor.
Why Marvell Is Paying So Much
Marvell’s case rests on its belief that demand for AI connectivity equipment will keep rising as technology companies build ever larger data centres. Modern AI systems do not rely on a single powerful machine; they depend on thousands of specialised processors working in concert, exchanging vast quantities of data without delay.
Marvell already supplies chips that process and transfer this information, while Lumentum supplies the optical parts that can carry it using light. Marvell estimates that the merged business could address a market opportunity worth approximately 550 billion dollars, and it also expects the takeover to produce more than 1 billion dollars in annual cost savings over time.
Both figures deserve a note of caution, because they are the company’s own projections rather than guaranteed outcomes. Still, a commitment of 115 billion dollars suggests Marvell’s leadership sees the market for AI connections as far from mature, and believes that owning both sides of the problem, chips and optics, will matter more than simply being good at one of them.
If the deal clears its regulatory hurdles and closes as planned in 2028, it will reshape a corner of the technology industry that most consumers never see but nearly everyone depends on. The takeover may have been agreed between two companies few people have heard of, yet its effects could eventually be felt in how fast, how cheaply and how efficiently the digital world runs.
