Marvell Reaches $115 Billion Deal for Lumentum Holdings

Marvell Technology Inc. has reached a deal to buy data center optics maker Lumentum Holdings Inc. at an enterprise value of $115 billion, one of the biggest tech tie-ups ever, in a race to capitalize on the artificial intelligence boom.

The all-stock transaction will give Marvell shareholders 67% of the combined company, according to a statement confirming an earlier Bloomberg News report that the two Silicon Valley companies were nearing a pact. The deal is expected to close in the first half of 2028, the companies said.

On an equity basis, it’s the top M&A deal of the year and the largest ever in the global tech sector, excluding the SpaceX-xAI merger, data compiled by Bloomberg show. The transaction shows how AI is driving deals across almost all major sectors and regions, from chipmakers and other specialist tech suppliers, to data center operators and power utilities.

Lumentum shares fell as much as 12% in New York to $740.10. Marvell declined as much as 7.3% to $182.15. Heading into the announcement, Lumentum was valued at $76 billion as of Friday. Marvell was valued at $172.2 billion.
