- The transaction implies an enterprise value of $115 billion for Lumentum.
- The merger is expected to close in the first half of 2028, subject to shareholder and regulatory approvals.
- The two companies plan to bring electrical connectivity and optical communications technologies together in a combined portfolio.
Marvell Technology and Lumentum announced on 2 November 2026 that they had entered into a definitive agreement for Marvell to acquire Lumentum in an all-stock transaction. According to the announcement, made in Santa Clara and San Jose, the deal will combine electrical and optical technologies to address connectivity requirements in AI infrastructure. Lumentum shareholders will receive 4.5 Marvell shares for each Lumentum share they own.
Deal value and expected timeline
The announcement put the implied enterprise value of the transaction for Lumentum at $115 billion. Based on closing share prices on 28 October 2026, this represents a premium of approximately 23.9%. That date was described as the last trading day before market rumors about a potential transaction began. The boards of directors of both companies unanimously approved the agreement.
The merger is expected to close in the first half of calendar year 2028. It remains subject to approval by Marvell and Lumentum shareholders, regulatory clearances, and other customary closing conditions, so the transaction has not yet been completed. Following closing, current Marvell shareholders are expected to own approximately 67% of the combined company’s fully diluted equity, with Lumentum shareholders owning approximately 33%.
Why bring electrical and optical connectivity together?
Marvell operates in electrical and optical interconnect, network switching, custom XPU connectivity, and semiconductor technologies. Lumentum’s portfolio includes high-performance lasers, optical transceivers, optical circuit switching, and compound semiconductor manufacturing. The combined portfolio is intended to address a range of distances and topologies, from connectivity between distributed data centers to connections within advanced semiconductor packages.
The companies say that rising bandwidth demands as AI infrastructure expands, along with the physical limits of copper-based connections, are accelerating the shift to optical technologies. According to Marvell and Lumentum, designing the electrical and optical signal chain more closely together could help meet bandwidth, performance, and energy-efficiency requirements. This is one of the stated goals of the merger, not an outcome that has already been achieved.
The companies also said the combined business could have a total addressable market of $550 billion. They are additionally targeting more than $1 billion in annual cost synergies following the transaction. These are company projections; whether they are realized will depend on closing the deal and the combined company’s subsequent performance.
Potential impact on architecture and visualization workflows
The deal does not announce any direct changes to the design or rendering software used by architecture firms. Any impact is more likely to come indirectly, and over the long term, through the development of the cloud and data center infrastructure that runs these applications. Connectivity performance in data centers may matter to teams using large models, collaborative environments, or remote rendering services; however, the announcement includes no product news related to architecture software, workstations, or specific visualization services.
No information has been announced that would require offices or visualization teams to upgrade hardware or change licenses at this time. The merger is expected to close in the first half of 2028, subject to approvals. Assessing any potential impact will therefore require following future announcements about the combined company’s products and the solutions it will offer customers.
Leadership and financial expectations
Once the deal is completed, Marvell Chairman and CEO Matt Murphy is expected to lead the combined company. Three Lumentum directors, including Lumentum CEO Michael Hurlston, are expected to join Marvell’s board.
The companies expect the transaction to contribute to Marvell’s non-GAAP earnings per share in the first year after closing. This outlook and the cost synergy target should be viewed as company estimates tied to the completion of the deal and subsequent performance, not as confirmed results.

For architecture and visualization teams, this deal does not mean an immediate change to software or hardware. The key issue to watch is how data center connectivity technologies may, over time, affect cloud-based design, collaboration, and rendering services.
For firms in Turkey, it would be more prudent to wait for the closing conditions and concrete product announcements from the combined company rather than make an investment decision now. The transaction is targeted to close in the first half of 2028 and remains subject to approvals. No announcement has yet been made about costs, availability, or usage licenses for the architecture sector.
