Marvell Tech in Talks to Acquire Lumentum: Filling Optical Gaps, AI Optical Interconnect Footprint May Expand Further

According to a Bloomberg report on October 28, Marvell Tech (MRVL) is in advanced negotiations to acquire Lumentum (LITE), with an announcement potentially coming as early as next week. As of press time, neither party has confirmed the talks, no relevant documents have been filed with the U.S. Securities and Exchange Commission, and deal terms have not been disclosed, meaning negotiations could still fall through.

The scale of this transaction is substantial. Bloomberg estimates Lumentum's market capitalization at approximately $83 billion, while Marvell's stands at around $221 billion. Acquisitions typically involve a premium, though specific pricing has not been revealed. Bloomberg stated that if completed, this would be one of the largest deals in the history of the technology industry.

Why Lumentum? Marvell's core business involves designing custom AI chips and networking chips for cloud providers, with optical components being its weak spot. Lumentum manufactures lasers, optical modules, and optical circuit switches used for high-speed transmission within AI data centers, representing a key link in the transition from copper wires to optical links in data centers. Lumentum's CEO stated this month that its optical products are booked through early 2029, with roughly 70% of next year's demand for certain products unable to be met. Reports indicate that Marvell is already purchasing lasers from Lumentum; completing this acquisition would effectively secure control over a critical supply chain.

Where will the money come from? Marvell had approximately $3.92 billion in cash at the end of the quarter, far insufficient to cover a transaction of this magnitude, leading to widespread market expectations of a stock-heavy deal. Raymond James believes an all-stock transaction would avoid interest costs and result in less dilution to earnings per share, although existing shareholders' ownership stakes would be more diluted. Earlier this year, Marvell acquired Celestial AI for $3.25 billion in cash and stock and is still in the process of integration.

How does the market view this? Following the news, Lumentum rose about 8.6% in after-hours trading, while Marvell fell approximately 8.4%. During Thursday's session, Marvell dropped as much as 14%, while the Nasdaq-100 Index also weakened due to concerns over AI spending following earnings reports from tech giants. 24/7 Wall St. noted that the after-hours movement reflected market expectations of a premium for Lumentum, as well as concerns that Marvell shareholders might face dilution or take on debt.

What do analysts say? RBC Capital Markets believes the product portfolios of the two companies are highly complementary and strategically significant. However, RBC also pointed out that the deal logic would be most robust if Marvell were to simultaneously sell off Lumentum's pluggable module business.

Where are the risks? First, financing risk: insufficient cash requires additional share issuance or borrowing. Second, integration risk: with Celestial AI still being integrated, acquiring another large company could hinder Marvell's previously raised revenue target of $20 billion for fiscal year 2028. Third, customer risk: hyperscale cloud providers and NVIDIA may be reluctant to rely on an optical supplier controlled by a chip competitor. Fourth, regulatory risk: a transaction of this size will face strict regulatory scrutiny.

Additionally, NVIDIA purchased $2 billion worth of Lumentum's Series A convertible preferred shares in March this year. Upon conversion, NVIDIA could become a significant shareholder in Marvell, which will also influence the deal structure.

Lumentum is expected to announce its financial results around November 5, but the company has not yet confirmed the date.
