Chipmaker Marvell has agreed to buy laser and optics maker Lumentum in an all-stock deal that gives Lumentum an implied enterprise value of $115 billion [1]. The two companies say the merger targets connectivity inside AI data centers, where copper links are giving way to optical ones [1].
What are the terms of the deal?
Marvell will pay 4.5 of its own shares for each Lumentum share in an all-stock deal. Marvell says the deal values Lumentum at an implied enterprise value of $115 billion. [1] That works out to about $1,132 per Lumentum share, a premium of about 23.9% to the unaffected price of 28 October 2026 [1].

After closing, current Marvell stockholders would own about 67% of the combined company and Lumentum stockholders about 33% [1]. Matt Murphy stays chairman and CEO, and three Lumentum directors, including CEO Michael Hurlston, join Marvell's board [1].
Why does Marvell want Lumentum?
Marvell brings electrical and optical interconnect chips, network switching and custom AI silicon, while Lumentum makes high-performance lasers, optical transceivers and optical circuit switches [1]. The companies say together they can co-design the electrical and optical parts of AI networks and address a market they put at $550 billion [1].
AI infrastructure is undergoing a fundamental architectural shift toward optical connectivity, creating an opportunity that comes along once in a generation,
When could the deal close?
Marvell expects the deal to close in the first half of 2028, subject to approvals. [1] Both companies' stockholders must approve it, and it needs antitrust clearance under the U.S. HSR Act and other regulatory approvals [1][2]. The filing says Marvell would owe Lumentum a $3.2 billion fee if the deal fails in certain regulatory circumstances [2].
Our read
Opinion: This is a bet that the next bottleneck in AI clusters is moving data, not computing it. A close date in 2028 is a long time in AI hardware, so regulators and customers like the big cloud companies will shape whether the logic still holds by then.
What we could not verify
- How regulators in the U.S., China and elsewhere will view the deal; no review has started publicly.
- How the stock market valued the deal after the announcement; we did not have a primary market source.
- Whether the targeted cost synergies of more than $1 billion a year will be reached.
