One of Tech’s Biggest Acquisitions Happened Between Companies You Never Heard Of

You might be unfamiliar with Marvell Technology or Lumentum, yet together they have been involved in one of the largest technology acquisitions in recent history. The US semiconductor company Marvell has announced its plan to acquire Lumentum, a firm specializing in optical chips and networking equipment, for roughly $115 billion, including debt.

This deal surpasses both Microsoft's $68.7 billion purchase of Activision Blizzard and Dell's $67 billion acquisition of EMC, thereby establishing itself as one of the most substantial technology acquisitions ever announced.

The peculiar aspect of this deal is that both companies play a crucial role in the rapidly expanding artificial intelligence sector, and both have received significant investments from Nvidia. Let's delve deeper into what Marvell and Lumentum actually do. Marvell Technology devises specialized semiconductors utilized in data centers, networking equipment, and AI computing systems. These chips assist in managing and processing the vast volumes of data necessary for cloud services and artificial intelligence applications.

Conversely, Lumentum focuses on optical technologies, encompassing lasers and components that transmit information via light. These technologies are becoming increasingly significant as AI data centers expand, necessitating faster communication among thousands of processors. Traditional copper connections become impractical when transferring substantial data over extended distances. Optical connections excel by transmitting data at high speeds while enhancing energy efficiency.

Upon merging their technologies, Marvell and Lumentum seek to develop swifter and more efficient connectivity systems for forthcoming AI data centers. On November 2, Marvell announced it would acquire Lumentum via an all-stock transaction. Consequently, Marvell will pay for the acquisition using its shares instead of cash. Lumentum shareholders will receive 4.5 Marvell shares for each Lumentum share they possess.

After completion of the deal, Marvell's existing shareholders will hold around 67% of the merged entity, whereas Lumentum shareholders will own the remaining 33%.

Matt Murphy, Marvell's chairman and CEO, will retain his position leading the combined business. Furthermore, three members of Lumentum's board, including CEO Michael Hurlston, will join Marvell's board. The companies anticipate the acquisition to finalize during the first half of 2028, contingent on shareholder and regulatory approvals.

A key point to note is Nvidia’s involvement with both Marvell and Lumentum. In March 2026, Nvidia pledged a $2 billion investment in Lumentum as part of a collaboration aimed at advancing optical technologies. This investment supported Lumentum's research, manufacturing expansion, and the development of laser components for AI infrastructure.

Later that month, Nvidia disclosed a separate $2 billion investment in Marvell. This agreement concentrated on bolstering AI infrastructure connectivity, including optical networking and semiconductor technologies. In total, Nvidia's investments in the two companies amount to $4 billion. These partnerships underscore the increasing importance of networking technology in the AI industry.

As AI systems grow more potent, companies require faster and more efficient methods to interconnect processors, servers, and data centers. Marvell posits that the merged entity could seize a market opportunity valued at approximately $550 billion. The company further anticipates generating over $1 billion in annual cost savings following the acquisition. However, these projections are estimates, not guaranteed outcomes.
