The chipmaker could gain control of laser and optics technology that is sold out for years, but Breakingviews warns the price may outrun the payoff
Marvell Technology is reportedly in advanced talks to acquire Lumentum Holdings, the laser and optical components maker whose products help shuttle data around AI data centers. Bloomberg reported the discussions on Wednesday, October 28, 2026. It said an all-stock deal could be announced as soon as the week of November 3.
What’s on the table
Lumentum’s market capitalization is estimated at roughly $83 to $85 billion. Marvell itself is valued somewhere between $196 and $221 billion, based on figures at the time of the report.
The strategic logic is fairly clean. Marvell makes digital signal processors, the chips that clean up and interpret signals moving through high-speed networks. Lumentum makes the lasers and optics that turn those signals into light and send them across fiber.
A sold-out supplier with a famous shareholder
Lumentum is not a company struggling to find customers. Earlier in October, CEO Michael Hurlston said key optical products are sold out until early 2029. He also pointed to a significant supply shortfall for certain products expected by 2027.
Lumentum also has a notable backer. Nvidia owned a $2 billion stake in Lumentum as of March 2026 and is a customer of the company.
Investors split the difference, badly for Marvell
The initial market reaction followed a familiar script. Lumentum shares climbed by 9% to 14% after the news. Marvell shares fell by 8% to 14% in after-hours trading.
Reuters Breakingviews made that case explicitly. The commentary argued that Marvell may have found an expensive shortcut in the race to move AI data at light speed. It said the potential acquisition may cost too much and deliver inadequate returns.
Marvell’s shopping habit
This would not be Marvell’s first big swing at AI infrastructure. In December 2025, the company agreed to acquire Celestial AI for $3.25 billion, a figure that could rise to $5.5 billion if certain milestones are met.
Marvell has also raised its fiscal 2028 revenue target to $20 billion.
The size jump is striking, though. Going from a deal worth up to $5.5 billion to a target valued at more than $80 billion is less a next step than a leap across several staircases.
What this means for the AI supply chain
For Marvell shareholders, the core question is dilution versus control. An all-stock deal of this scale would hand Lumentum investors a meaningful share of the combined company. In exchange, Marvell would gain a supplier whose products are spoken for into 2029.
The bear case is what Breakingviews flagged. When a target is already priced for years of sold-out demand, much of that good news is baked into the valuation. The acquirer pays for future growth upfront and must then outperform those expectations just to break even on the investment.
The near-term marker is the week of November 3. If an announcement lands, investors will be looking for the exchange ratio, any synergy targets, and how Marvell plans to address Lumentum’s capacity shortfall.
