THE ESSENTIALS IN 30 SECONDS

  • Lumentum shareholders will receive 4.5 Marvell shares per share, an implied enterprise value of about $115 billion; they would own about 33% of the combined company.
  • The companies target a combined addressable market of about $550 billion by 2030 and say they see more than $1 billion in annual run-rate synergies, mostly in cost of goods sold.
  • Closing is expected in the first half of 2028, subject to approval by both companies' shareholders and by regulators; the merger agreement's outside date is November 1, 2027, extendable into 2028.

Marvell Technology has agreed to acquire Lumentum, a maker of lasers and optical components used in AI data centres, in an all-stock transaction announced on November 2. Media reports put the implied enterprise value at about $115 billion, including debt. The merger agreement, which Lumentum filed with the US Securities and Exchange Commission, was signed on November 1.

The terms

Each Lumentum share will be converted into 4.5 Marvell shares. Investing.com and The Next Web put the implied value at roughly $1,132 per Lumentum share, a premium of about 23.9% to the October 28 close, the last trading day before talks were reported. On a fully diluted basis, Marvell shareholders would hold about 67% of the combined company and Lumentum shareholders about 33%, according to the investor presentation.

Both boards approved the deal unanimously. Matt Murphy stays chairman and chief executive, while three Lumentum directors, including CEO Michael Hurlston, will join Marvell's board. The filing sets break fees of $5.8 billion payable by Marvell and $2.9 billion by Lumentum in certain cases, plus a $3.2 billion fee Marvell would owe if the deal fails on antitrust or other regulatory grounds.

The rationale

Marvell designs custom AI chips, network switches and electrical interconnect; Lumentum brings lasers, optical transceivers, optical circuit switches and its own wafer fabs. In letters to customers, Marvell argues that copper links are hitting their limits as AI bandwidth grows, and that tighter co-design of electrical and optical parts will speed up products. The presentation targets a combined addressable market of about $550 billion by 2030 and cites line of sight to more than $1 billion in annual run-rate synergies, mainly in cost of goods sold. Marvell expects the deal to add to its adjusted earnings per share in the first year after closing, without giving a figure.

What comes next

The transaction needs approval from both sets of shareholders, US antitrust clearance and other regulatory approvals, and a registration statement must still be filed. Marvell says it expects to close in the first half of 2028; the agreement's outside date is November 1, 2027, extendable in stages to August 2028 if regulatory reviews drag on. Until then the companies operate separately, and Lumentum's name and brand will eventually be folded into Marvell, according to an employee FAQ.
