Marvell to Acquire Lumentum for $115 Billion Amid AI Infrastructure Surge

Marvell Technology has agreed to acquire datacentre optics maker Lumentum in an all-stock mega-deal valued at $115 billion, positioning the combined entity to capture a surging global market for artificial intelligence hardware infrastructure.

Under the terms of the agreement, Lumentum shareholders will receive a fixed exchange ratio of 4.500 shares of Marvell common stock for each share they own. The arrangement will result in Lumentum investors holding approximately 33 percent of the newly combined company. The transaction is projected to close in the first half of next year, pending regulatory clearances and shareholder approval.

Matt Murphy, chair and chief executive of Marvell, described the transaction as a response to a once-in-a-generation shift in computing architecture. AI infrastructure is undergoing a fundamental transition toward optical connectivity, Murphy noted, adding that the integration of the two firms brings together complementary technologies and specialized manufacturing capabilities.

Michael Hurlston, president and chief executive of Lumentum, stated that the merger creates an organization uniquely positioned to address an estimated $550 billion market opportunity. Hurlston emphasized that surging AI data traffic demands rapid hardware innovation, and the combined portfolio will support customers across scale-across, scale-out, scale-up, and scale-in domains.

Upon completion of the merger, three Lumentum directors—including Hurlston—will join Marvell’s current seven-member board of directors. While Marvell shares experienced a decline of more than 20 percent after reports of the talks first surfaced last month, the stock rose 4 percent in pre-market trading following the formal announcement, with Lumentum projected to gain 2.5 percent.

Industry analysts note that Lumentum, which competes internationally with firms such as Coherent and Zhongji Innolight, stands to benefit from proposed regulatory measures restricting certain imported optical transceivers, a policy shift that could increase domestic demand for US suppliers.
