Marvell Technology signed the Marvell Lumentum deal on Monday, November 2, 2026, agreeing to buy optical components maker Lumentum in an all-stock transaction with an implied enterprise value of $115 billion. It’s one of the biggest deals of 2026, Reuters reported, and it turns last week’s takeover talks into a signed agreement with a price, a share ratio, and a closing target.
Under the terms announced by both companies, Lumentum stockholders will receive a fixed 4.500 Marvell shares for each Lumentum share they own. That works out to about $1,132 per Lumentum share, a 23.9% premium to both companies’ unaffected closing prices on October 28, the last trading day before reports of the talks surfaced. Reuters put the equity value at $102.54 billion; the higher $115 billion enterprise figure includes debt, which is why the two numbers differ.
Talks are over.
What the Marvell Lumentum deal actually pays
No cash changes hands in this transaction, and that detail matters more than the headline number. Because the exchange ratio is fixed at 4.500 shares, the dollar value Lumentum holders ultimately receive will move with Marvell’s share price every day until closing. If Marvell’s stock rises, the deal gets richer. If it falls, the headline $115 billion shrinks, even though the share count stays the same.
Ownership splits the same way. Current Marvell stockholders will own about 67% of the combined company on a fully diluted basis, while Lumentum stockholders will own about 33%. Both boards approved the agreement unanimously, Marvell chairman and CEO Matt Murphy will lead the combined company, and three Lumentum directors, including Lumentum CEO Michael Hurlston, will join Marvell’s board.
Don’t mistake a signed agreement for a done deal. Shareholders of both companies still have to approve it, regulators still have to clear it, and the companies don’t expect closing until the first half of calendar 2028.
What Marvell is actually buying
Lumentum makes lasers, optical transceivers, optical circuit switches, and compound-semiconductor parts. In plain terms, it builds the components that move data as light inside communications networks and data centers. Marvell, based in Santa Clara, California, makes custom AI chips and networking products, including the electrical and optical interconnect pieces that sit next to those lasers.
Put together, Marvell would sell more of the chain that connects AI hardware. A modern AI cluster spreads work across thousands of chips at once, and those chips have to exchange data constantly. Copper links struggle as speeds climb and distances grow inside a data center. Light travels faster, uses less power over distance, and has become the default answer for the fastest links between racks.
That’s why the timing fits, even at this price. Demand for optical parts has been outrunning supply as hyperscale customers build bigger clusters, and Reuters reported that Marvell is betting that demand stays strong enough to justify buying a company roughly half its size.
From talks to a signed agreement in five days
Bloomberg News first reported on October 28 that Marvell was in advanced talks to buy Lumentum. Lumentum shares jumped about 11% in extended trading that evening, and Marvell shares fell more than 8%, as investors weighed a price tag far larger than Marvell’s cash pile. By the following days, the split had widened rather than closed.
Since the talks were first reported, Lumentum shares have fallen about 8% and Marvell shares about 22%, Reuters reported on Monday, as a broad chip selloff accelerated after Intel’s weak forecast. Monday’s session didn’t calm that reaction: Marvell rose in premarket trading while Lumentum trading was halted, then both stocks slid after the announcement, with market coverage putting Marvell down more than 3% and Lumentum down about 8%.
Why this matters for AI data centers
Marvell’s pitch is scale: the combined company would address a market opportunity of $550 billion, according to the companies’ own estimate. Treat that figure as positioning, not a forecast, since it’s Marvell’s number and covers every adjacent market the two companies touch. Still, the direction is clear. Chip companies no longer want to sell one piece of an AI system while someone else owns the links between the pieces.
“Joining Marvell creates a company uniquely positioned to capitalize on a market opportunity of $550 billion and generate significant, sustainable stockholder value,” Lumentum CEO Michael Hurlston said in the announcement.
Investors aren’t buying that story yet, and their skepticism is rational. A fixed share ratio means Marvell holders absorb the risk if the stock slides before 2028, and a deal this large invites a long regulatory review in the US and abroad.
If the deal closes on schedule, Marvell becomes a much broader AI infrastructure supplier in a single move, selling chips, networking, and optics together. If it stalls, the message will be just as clear: even the winners of the AI spending boom can’t buy growth at any price without shareholders pushing back.
Frequently asked questions
Is Marvell buying Lumentum?
Yes. Marvell and Lumentum announced a definitive agreement on November 2, 2026, under which Marvell will acquire Lumentum in an all-stock transaction with an implied enterprise value of $115 billion.
What will Lumentum shareholders receive?
Each Lumentum share will convert into a fixed 4.500 Marvell shares, worth about $1,132 per share based on the companies’ unaffected closing prices on October 28, 2026. After closing, Lumentum holders will own about 33% of the combined company.
When will the Marvell Lumentum deal close?
The companies expect closing in the first half of calendar 2028, subject to approval by both sets of shareholders and to regulatory clearances. Until then, Marvell and Lumentum will keep operating as separate companies.
Why does Marvell want an optics company?
AI data centers move huge amounts of data between thousands of chips, and optical links carry that traffic as light instead of electrical signals over copper. Owning Lumentum gives Marvell the lasers and optical parts behind those links, alongside its own chips and networking products.
