Marvell Technology Agrees to Buy Lumentum in $115 Billion All-Stock Transaction
AI infrastructure is undergoing a fundamental architectural shift toward optical connectivity, creating an opportunity that comes along once in a generation,
Marvell Chairman and CEO Matt Murphy said in a release detailing a massive consolidation move within the semiconductor sector.
Marvell Technology announced on Monday that it has agreed to acquire optical components maker Lumentum in a fixed-ratio, all-stock transaction. The deal carries an implied enterprise value of $115 billion for Lumentum. The tie-up ranks as the largest mergers and acquisitions deal of 2026 by equity value, which stands at $102.54 billion according to Reuters.
Under the terms of the agreement, Lumentum shareholders will receive 4.5 Marvell shares for each Lumentum share they own. This exchange equals about $1,132 per Lumentum share, representing a 23.9% premium over the closing price on Oct. 28, which was the final trading day before market speculation regarding a potential deal emerged. On a fully diluted basis, Marvell stockholders will own approximately 67% of the combined company, while Lumentum stockholders will hold the remaining 33%.
Board Composition and Leadership Structure After the Closing
The boards of directors at both Marvell and Lumentum unanimously approved the transaction. Following the expected closing, Matt Murphy will continue in his role as Marvell’s chairman and CEO. Three directors from Lumentum, including Lumentum CEO Michael Hurlston, will transition to Marvell’s board, which will have seven directors in total.
The transaction requires approvals from the stockholders of both Marvell and Lumentum, alongside necessary regulatory clearances and customary closing conditions. Both companies anticipate the deal will close during the first half of calendar 2028. Ahead of the opening bell following the announcement, Marvell shares climbed 2.8%, while a trading halt kept Lumentum shares from trading.
Combining Electrical and Optical Technologies for Artificial Intelligence
Marvell stated that the acquisition will merge its electrical technologies with Lumentum’s optical components to address accelerating and shifting artificial intelligence connectivity demands across various systems and regions. Technology companies are increasingly relying on optical connections to link the specialized chips used to train and run large language models.
The combined enterprise expects the transaction to expand their total addressable market to $550 billion. The companies projected the integration will provide a clear line of sight to more than $1 billion in annual run-rate cost synergies while adding to Marvell's non-GAAP earnings per share during the first year following the completion of the deal.

Prior Acquisitions and Market Context in 2026
This transaction marks one of the most significant bets on artificial intelligence infrastructure in 2026, arriving despite recent investor concerns regarding the long-term sustainability of heavy infrastructure spending. Marvell has expanded its footprint through targeted optical investments recently, closing a deal for optical interconnectivity startup Celestial AI in February for $3.5 billion.
The Lumentum acquisition stands as Marvell’s largest deal since it paid $10 billion to acquire Inphi in 2021. Buoyed by unrelenting artificial intelligence enthusiasm, Marvell has watched its market value more than triple over the last three years, while Lumentum’s stock has more than doubled across 2026 alone. Alongside the acquisition announcement, Marvell reported preliminary revenue for its fiscal third quarter of 2027 that aligned with previous guidance, narrowing its expected range to plus or minus 2%.
