Marvell to Acquire Lumentum in Major Tech Deal

Custom chip designer Marvell has signed an agreement to acquire optical chip and networking equipment maker Lumentum. The acquisition is an all-stock deal with an implied enterprise value of $115 billion, including debt, and an equity value of approximately $80 billion. This transaction ranks among the largest acquisitions in tech history, comparable to Microsoft's acquisition of Activision Blizzard for $68.7 billion in 2022 and Dell's purchase of EMC for $67 billion in 2016.

Focus on AI Connectivity Leadership

Marvell stated that the acquisition of Lumentum will position it as a leader in AI connectivity. The combined entity will offer products ranging from chips to data centers, integrating electrical and optical technologies. This move is intended to address the increasing connectivity demands driven by the buildout of artificial intelligence infrastructure.

Lumentum CEO Michael Hurlston noted the "enormous" opportunity presented by the deal in meeting these demands. Marvell CEO Matt Murphy indicated the merger would create a "new category of company" by seamlessly combining semiconductor and optical scale-up technology.

Deal Structure and Shareholder Information

Under the terms of the agreement, Marvell will provide 4.5 shares of its common stock for each share of Lumentum. As a fixed-ratio stock deal without cash, the final value will depend on Marvell's share price. Following the announcement, Marvell shares declined 13% and Lumentum's stock fell nearly 19% in trading.

Nvidia is a significant common shareholder in both companies. In March, Nvidia invested $2 billion in Lumentum to support its R&D and fab expansion, and later that month, invested $2 billion in Marvell to enhance its optical networking and chips portfolio.

Timeline and Approvals

The transaction is anticipated to close in the first half of calendar year 2028. Completion of the deal is contingent upon approval from both companies' shareholders and regulatory bodies.
