Marvell Technology has agreed to acquire optical components maker Lumentum in an all-stock deal that Marvell values at about $115 billion including debt, making it one of the largest technology acquisitions on record. The companies announced the agreement on Monday, November 2, 2026. The merger agreement itself is dated November 1.
The terms
Each Lumentum share will convert into 4.5 Marvell shares, with cash paid in place of fractional shares, according to Marvell's press release and Lumentum's regulatory filing. Marvell says that works out to about $1,132 per Lumentum share, based on closing prices on October 28, the last day before talk of a deal surfaced. It describes that as a premium of about 23.9 percent.
The headline figure needs care. Reuters reports that the $115 billion enterprise value includes debt and puts the equity value at about $102.5 billion. Marvell's release and the other coverage we read do not give a separate equity number, so treat the gap between the two figures as Reuters' framing.
After closing, Marvell shareholders would own about 67 percent of the combined company and Lumentum shareholders about 33 percent on a fully diluted basis. Matt Murphy stays chairman and chief executive. Three Lumentum directors, including its chief executive Michael Hurlston, would join Marvell's board.
Why optical matters
Marvell designs the custom chips and networking silicon that connect AI servers inside data centres. Lumentum makes the lasers and optical parts that carry data between them as light. Marvell says the combination creates a category leader in AI connectivity and sees a combined market opportunity of about $550 billion. It also points to line of sight to more than $1 billion in annual run-rate cost savings and expects the deal to add to its adjusted earnings per share in the first year.
Murphy called it "an opportunity that comes along once in a generation." Reuters reports the combined company would have more than $21 billion in annual revenue, with adjusted operating margins in the low 40 percent range. Lumentum reported fiscal first-quarter revenue of $1.26 billion on Monday and guided to $1.575 billion to $1.625 billion for the next quarter, according to Yahoo Finance's report of its results.
Investors did not cheer
Both stocks fell hard. Reuters says Marvell dropped more than 10 percent and Lumentum more than 15 percent in trading on Monday, and Motley Fool's midday report put the two companies' combined market value loss at nearly $28 billion. Because the exchange ratio is fixed, the offer is worth less as Marvell's share price falls. At midday prices, Motley Fool calculated an implied value of about $800 per Lumentum share, roughly $81 billion, well below the headline figure.
Reuters also reports the price represents about 33 times Lumentum's projected core operating profit, against a median of roughly 16 times for peers. Axel Rudolph of IG Group called the deal an "enormous bet" in Reuters' report, and said investors may ask whether Marvell is paying too much. Those are analyst views, not company statements. Closing figures for the day were not available in the sources we read, so the moves above are intraday snapshots.
A big step for Marvell
Marvell's market value was about $170 billion before the announcement, according to Reuters, and its largest earlier acquisition was Inphi, bought for about $10 billion in 2021. Reuters adds that Nvidia invested $2 billion in each of Marvell and Lumentum earlier this year, which ties both companies closely to the biggest buyer of AI hardware. Murphy told CNBC the deal doubles down on supporting Nvidia, as relayed by Reuters.
Conditions and a long road
The deal needs approval from shareholders of both companies, antitrust clearance in the United States under the Hart-Scott-Rodino Act and other regulatory approvals, an effective registration statement and Nasdaq listing approval. Marvell expects it to close in the first half of 2028. The merger agreement sets an outside date of November 1, 2027, extendable to as late as August 2028 in certain regulatory situations.
The agreement also includes steep break fees. Lumentum's filing shows Marvell would pay Lumentum $5.8 billion in specified cases, Lumentum would pay Marvell $2.9 billion, and Marvell would owe $3.2 billion if regulators block the deal. Marvell also kept its guidance for its current quarter's revenue midpoint and narrowed the range, according to its release. No financing package or cash component is disclosed, since the deal is paid in shares.
What to watch next
The first test is the share price. Because the ratio is fixed, every move in Marvell's stock changes what Lumentum holders receive, and activist or rival interest from other bidders would be a surprise worth noting. Next is regulatory scrutiny, since both firms supply parts to the same small group of AI hardware buyers. Filings of the joint proxy statement should add detail on how the two boards reached the price, and Nvidia's reaction as a shareholder in both companies is worth watching.
