Marvell Technology is reportedly closing in on a deal to buy data-center optics maker Lumentum Holdings in a transaction valued at more than $80 billion, a potential megadeal that would hand the Santa Clara semiconductor company much greater control of technology critical to powering digital infrastructure. No final agreement has been reached, and the talks could still fall apart before any announcement.
The talks were first reported by Bloomberg, which described Marvell as being in advanced talks to acquire the company. Bloomberg separately reported that the deal is expected to be all stock, though terms had not been finalized. An agreement could be announced as soon as the week of November 2, according to people familiar with the matter cited by Yahoo Finance, though no final deal had been reached and the talks could still end without one. As of Thursday, neither company had publicly confirmed the discussions, the outlet noted.
Lumentum makes lasers and other optical components used to move large volumes of data at high speed across communications networks and data centers, per the same account. Marvell, for its part, designs semiconductors for AI and data-center applications. Acquiring a major optics supplier would deepen Marvell's position in that part of the AI supply chain, Yahoo Finance reported.
A Supplier That's Already Sold Out Through 2029
The urgency behind any deal may trace back to capacity. Lumentum's optical component capacity was effectively sold out through early 2029, according to 247 Wall St., which also reported that Lumentum Chief Executive Michael Hurlston said the company could not satisfy roughly 70% of anticipated demand for certain products through 2027. That bottleneck underscores just how stretched the optics supply chain has become as AI workloads drive demand for faster data transmission, as reported by Reuters.
Marvell and Lumentum aren't strangers to collaboration. The two companies previously demonstrated interoperability between Marvell's optical connectivity solutions and Lumentum's optical circuit-switching platform, according to a Marvell announcement. That switching technology enables direct optical paths between endpoints in AI data-center networks while reducing power consumption and eliminating intermediate packet processing, the company said. Lumentum has also pointed to 1.6T optical modules and 200G-per-lane technologies moving from feasibility into deployment, alongside co-packaged optics advancing from concept toward industrialization, according to a Lumentum blog post.
Wall Street's Reaction Is Anything But Unified
Investors clearly didn't agree on who wins this trade. Marvell shares fell 12% Thursday while Lumentum's climbed more than 4% in early trading, per Yahoo Finance. Investopedia, however, put the numbers differently, reporting Marvell down more than 11% in recent trading while Lumentum rose 2.5%. Reuters had yet another snapshot, reporting that in extended trading after the initial report, Lumentum shares jumped about 9% while Marvell fell more than 8%.
The market-value estimates behind the deal talk are similarly scattered across outlets. Bloomberg put Lumentum's market value at about $85 billion against Marvell's roughly $196 billion, while Yahoo Finance cited Lumentum at about $83 billion versus Marvell's $221 billion. Investopedia reported Lumentum's market capitalization at approximately $82.8 billion as of the prior day's close, with Marvell just over $220 billion. Morningstar, meanwhile, noted that Lumentum is up 148% year to date and sits at roughly $83 billion in market cap before any acquisition premium, while maintaining a $360 fair-value estimate for Marvell and a $750 valuation for Lumentum.
How Marvell Might Pay For It
Marvell's cash position raises questions about how a deal of this size would actually get financed. The company had about $3.92 billion in cash and cash equivalents as of its latest quarter, according to Reuters, a figure dwarfed by the reported deal valuation — one reason the transaction is expected to be structured as all stock rather than cash. It wouldn't be Marvell's first optics-related purchase this cycle: the company's acquisition of photonics firm Celestial AI was announced at a value of $3.25 billion late in the prior year, Reuters reported, a comparatively modest deal next to the figures now being discussed for Lumentum.
Lumentum's strategic value extends beyond any one suitor. The company has a nonexclusive agreement with NVIDIA that includes a multibillion-dollar purchase commitment and future capacity access rights for advanced laser components, according to an NVIDIA announcement. That relationship adds another layer of complexity to any Marvell transaction, given how central Lumentum's optics have become to the broader AI buildout.
For now, the deal remains unconfirmed by either company, and the path forward is far from settled. Whether an agreement materializes as soon as next week, as some reports suggest, or the talks collapse entirely, the scramble for optical capacity that triggered this reported megadeal isn't going away anytime soon.
