Marvell to buy Lumentum in $115 billion deal in AI data-center bet

The acquisition expands Marvell’s photonics and interconnect business as AI data-center demand drives a 65% annual growth forecast through 2030, the company said.

  • On Monday, Marvell Technology announced it is buying optical components maker Lumentum in a $115 billion all-stock deal, aiming to challenge rival Broadcom and capitalize on the AI spending boom.
  • "Infrastructure is undergoing a fundamental architectural shift toward optical connectivity," said Marvell CEO Matt Murphy, who will remain chairman and CEO of the combined company. The deal expands the company's total addressable market to $550 billion.
  • Big Tech's AI spending boom drives demand for optical components used to move data at high speeds. Reflecting this confidence, AI chip giant Nvidia invested $2 billion each in Marvell and Lumentum earlier this year.
  • To challenge Broadcom, the deal integrates Lumentum into Marvell's portfolio. Since talks were reported late last month, Lumentum's shares have fallen about 8% and Marvell about 22%, as a broad-based chip selloff accelerated following Intel's weak forecast.
  • Marvell expects the interconnect market to grow 65% a year to $65 billion by 2030, fueling long-term demand. The transaction, unanimously approved by both boards, is expected to close in the first half of calendar 2028.
