Marvell Announces All-Stock Acquisition of Lumentum for $115 Billion
Marvell Technology has agreed to acquire optical component manufacturer Lumentum in an all-stock transaction with an implied enterprise value of approximately $115 billion. Under the agreement, Lumentum shareholders will receive 4.5 shares of Marvell common stock for each share they own, representing a 23.9% premium. This mega-acquisition combines Marvell's expertise in semiconductor and networking technology with Lumentum's optical components, significantly expanding their capabilities in AI data center infrastructure and optical interconnects. The combined company aims to capture a massive share of the growing $550 billion total addressable market. The transaction is expected to close in the first half of 2028, pending regulatory and shareholder approvals, and is projected to yield over $1 billion in annual cost synergies. Meanwhile, Lumentum reported strong fiscal Q1 2027 results with revenue surging 136.5% year-over-year to $1.263 billion, largely driven by demand for pump lasers and optical circuit switches (OCS).
## BACKGROUND
Optical interconnects use light waves instead of electrical signals to transmit data at high speeds with low latency, becoming essential for connecting modern large-scale AI computing clusters. Lumentum specializes in optical components like lasers and optical circuit switches (OCS), which route data traffic optically to overcome the physical bottlenecks of traditional copper wiring.
