The $115 billion all-stock valuation makes this the largest technology deal on record, with Marvell shareholders holding 67 percent of the combined company and Lumentum investors holding the remainder. Closing is not expected until the first half of 2028, and the source does not address regulatory approval timing.

Market Landscape

The transaction reflects consolidation pressure in the data center hardware market as AI workloads drive demand for faster optical and networking components.
