1. The Agreement

On November 2, 2026 (US time), Marvell and Lumentum announced a definitive agreement under which Marvell will acquire Lumentum in an all-stock transaction. The merger agreement is dated November 1, and Lumentum will become a wholly owned subsidiary of Marvell through a two-step merger. Both boards approved the deal unanimously.

Consideration: Lumentum shareholders will receive 4.500 shares of Marvell common stock for each Lumentum share. The exchange ratio is fixed, and fractional shares will be paid in cash
Implied enterprise value: According to the companies, based on both companies' share prices on October 28, Lumentum's implied enterprise value is $115 billion, or about $1,132 per share. They describe this as a premium of about 23.9% to the close on October 28, the last trading day before deal speculation reached the market
Equity value: The announcement does not state an equity value (purchase price), and media figures differ, so this article uses the implied enterprise value given by the companies
Ownership after closing: On a fully diluted basis, current Marvell shareholders are expected to own about 67% and Lumentum shareholders about 33%
Leadership: Marvell's Matt Murphy will remain Chairman and CEO. Three Lumentum directors, including Lumentum CEO Michael Hurlston, will join Marvell's board, which currently has seven members

Because the exchange ratio is fixed, the value of the deal moves with Marvell's share price. Marvell shares have fallen sharply since October 28, so at current prices the per-share value is well below the roughly $1,132. Bloomberg reported the talks on October 28. On announcement day, November 2, Marvell shares fell about 13% and Lumentum shares about 19%, according to CNBC.

2. Conditions and Timeline

Shareholder approval: Lumentum shareholders must adopt the merger agreement, and Marvell shareholders must approve the share issuance and a charter amendment that increases the number of authorized shares
Regulatory approval: The only regime named in Marvell's Form 8-K is the expiration or termination of the waiting period under the US HSR Act (antitrust pre-merger notification). For the other "required regulatory approvals", no countries or regions are listed
Outside date: The outside date is November 1, 2027. If regulatory approvals are still pending, it can be extended to February 1, May 1 and August 1, 2028
Termination fees: In certain circumstances, such as a change in board recommendation or a superior proposal, Marvell would pay Lumentum $5.8 billion, and Lumentum would pay Marvell $2.9 billion
Regulatory termination fee: If all non-regulatory conditions are met but the deal misses the outside date, a final restraint is issued under antitrust or foreign investment laws, or a required approval is finally denied, Marvell would pay Lumentum $3.2 billion

Marvell's 2021 acquisition of Inphi, a large optical-interconnect deal, reportedly closed about one month after China approved it (CNBC). As of November 4, the countries and regions that will review this deal have not been disclosed.

3. Size of the Two Companies

Lumentum

Fiscal Q1 2027 (three months ended September 26, 2026): Revenue was $1,262.6 million, up 136.5% year over year. GAAP net income was $360.3 million
Outlook for next quarter: Lumentum expects revenue of $1,575 million to $1,625 million. Its CEO said the quarter brought a second major NPO/CPO win (placing optics right next to or in the same package as the chip), backed by more than $5 billion in purchase commitments
Fiscal 2026 (ended June 27, 2026): Revenue was $3,014.0 million (up from $1,645.0 million the year before), and Lumentum had about 13,757 employees
Customer concentration: In the latest quarter, two end customers accounted for 37% and 11% of revenue (their names are not disclosed)

Marvell

Fiscal Q2 2027 (reported August 27): Revenue was a record $2,739 million, up 37% year over year. Data center revenue was $2,171.5 million (79%)
Preliminary fiscal Q3: With the deal announcement, Marvell said fiscal Q3 revenue is in line with guidance ($3,150 million ±5%), keeping the midpoint and narrowing the range to ±2%
Fiscal 2026 (ended January 31, 2026): Revenue was $8,194.6 million (up 42.1%), of which data center was $6,100.3 million (74%)

Figures in the Investor Presentation

Combined revenue: Annualized revenue is $12.6 billion for Marvell (based on the midpoint of its fiscal Q3 guidance) and $5.1 billion for Lumentum (based on fiscal Q1 2027 actuals), for a combined $17.7 billion (excluding synergies)
Addressable market: The companies say the deal expands their 2030 addressable market to $550 billion, citing Marvell's $400 billion and Lumentum's more than $90 billion forecasts. The companies expect the combined platform to unlock additional opportunities beyond the simple sum (more than $490 billion)
Synergies: They see more than $1 billion in annual cost savings (mainly cost of goods sold) and expect the deal to add to Marvell's non-GAAP earnings per share in the first year after closing. No timeline for the savings is given

Nvidia's Investments

Lumentum (March 2, 2026): Nvidia signed multi-year agreements with Lumentum, including a multi-billion-dollar purchase commitment and future capacity rights for advanced laser components, and bought $2 billion of Lumentum convertible preferred stock in connection with a new US fab
Marvell (March 31, 2026): Nvidia bought $2 billion of Marvell convertible preferred stock. This followed a partnership to connect Marvell's custom AI processors and networking with Nvidia's AI ecosystem
Treatment in the merger: Under the merger agreement, Lumentum's convertible preferred stock will convert into Marvell common stock at the exchange ratio, or, at the holder's election, into new Marvell convertible preferred stock

4. The Rationale the Companies Give

The companies say they will combine Marvell's electrical and optical interconnect technology, network switching and custom AI processor (XPU) technology with Lumentum's high-performance lasers, optical transceivers, optical circuit switches (OCS) and compound semiconductor (InP) manufacturing. The presentation also lists DSPs, TIAs and drivers, light engines for CPO and NPO, and EML and CW lasers.

InP manufacturing: Lumentum's CEO said the company has the world's largest InP manufacturing footprint. This is the company's own claim and has not been independently verified
Previous consolidation: Marvell completed its acquisition of Inphi (optical interconnect chips, reported at about $10 billion) in April 2021 and of Celestial AI (chip-to-chip optical interconnect, $3.5 billion) in February 2026. Lumentum completed its acquisition of Oclaro (about $1.8 billion) in December 2018

5. The Optical Transceiver Market

Demand: In a September report, LightCounting said Ethernet optical transceiver sales doubled in 2024 and grew almost 90% in 2025, and it forecasts 120% growth in 2026. It describes this as the peak of the super-cycle in growth-rate terms
800G and 1.6T: According to LightCounting, unit shipments of 800G (2xDR4 and 2xFR4) and 400ZR and ZR+ in April–June 2026 were up to three times the level a year earlier. Volume shipments of 1.6T and 800ZR and ZR+ are also off to a strong start
Supply constraints: In April, LightCounting said market growth was limited by InP EML and laser chip capacity, with demand exceeding supply by 30%, and expected shortages to ease by the end of the year
Supply chain: TrendForce estimates that Chinese makers hold about 56% of global optical module contract manufacturing capacity in 2026. In August 2026, the US Federal Communications Commission (FCC) was reported to be considering restrictions on new Chinese-made transceivers, but no official document has been found and nothing is final

The 120% for 2026 is a forecast; LightCounting raised it from 65% in April to 120% in September.

Links to Japan

Sagamihara plant: Lumentum's annual report lists Japan as one of its significant manufacturing locations. In July 2024, the company bought the land and building of its wafer fabrication plant in Sagamihara, Kanagawa Prefecture, for $42.2 million
History of the plant: Lumentum took over the Sagamihara site from Oclaro, which it acquired in 2018. In 2012, Oclaro had acquired Opnext, a company formed from certain Hitachi assets
Japanese subsidiaries and shipments: Lumentum's Japanese subsidiaries are Lumentum Japan Inc. and Lumentum G.K. Revenue from shipments to Japan (by customer ship-to location) was $104.6 million in fiscal 2026, or 3.5% of the total. The ship-to location may differ from where the end customer is

6. What It Means for Data Centers and Compute

Connections inside AI data centers are moving from copper to optics, and this deal brings together a major interconnect chip maker and a major laser and optical component maker
The deal is still only an agreement, with closing expected in the first half of 2028. The timing could change depending on regulatory review
Demand for optical transceivers keeps growing, while laser chip capacity and supply chains, including China, are seen as challenges

We believe that as AI data centers add more optical connections, on-site work will also increase: installing optical transceivers and fiber, cleaning and inspection, replacement and returns (RMA), and equipment shipping. We will also continue to watch component lead times and supply chain developments.
