Marvell (NASDAQ:MRVL) to Buy Lumentum (NASDAQ:LITE) for USD 115 Billion: One of 2026's Biggest Deals Targets AI Optical Links

Key Highlights

• Marvell will acquire Lumentum in an all stock deal that values Lumentum at USD 115 billion in enterprise value.
• Each Lumentum share converts into 4.500 Marvell shares, a premium of about 23.9% to the October 28 close.
• Marvell holders will own about 67% of the combined company, with over USD 1 billion in annual savings targeted.
• Closing is expected in the first half of 2028, after stockholder and regulatory approvals.

Marvell Moves on Lumentum

Marvell Technology (NASDAQ:MRVL) will acquire optical components maker Lumentum (NASDAQ:LITE) in an all stock transaction that gives Lumentum an implied enterprise value of USD 115 billion, the companies announced on Monday, November 2, 2026. The deal is one of the biggest of the year and Marvell's largest purchase since it bought Inphi for USD 10 billion in 2021.

It also widens the contest between Marvell and Broadcom (NASDAQ:AVGO), the larger rival in custom chips for AI data centers, at a time when chip executives expect AI spending to support industry demand for years.

The Terms

Lumentum stockholders will receive a fixed 4.500 Marvell shares for each Lumentum share. The companies put that at about USD 1,132 per Lumentum share, a premium of roughly 23.9% to the closing prices of October 28, 2026, the last trading day before speculation about a deal began. With the ratio fixed, the value paid for each Lumentum share moves with Marvell's share price.

On a fully diluted basis, current Marvell stockholders will own about 67% of the combined company and Lumentum stockholders about 33%. Both boards approved the agreement unanimously. Closing is expected in the first half of calendar 2028, subject to votes by stockholders of both companies, regulatory approvals and customary conditions. Marvell plans to file a registration statement and joint proxy statement with the SEC.

Why Optics, and Why Now

The case the two companies make starts with bandwidth. AI clusters need to move far more data between chips, and copper links are reaching physical limits. As designs move toward scale up connections between processors in a system and scale in connections inside advanced chip packages, the industry is shifting from separate modular parts to integrated optical products, which require electrical and optical engineering to be done together.

Marvell chairman and CEO Matt Murphy called it an architectural shift toward optical connectivity and an opportunity that comes along once in a generation. Lumentum CEO Michael Hurlston said the combination lets the company serve a customer's whole interconnect need, from scale across and scale out connections today to scale up and scale in connections later. Both put the combined addressable market at USD 550 billion. The deal also rests on an expectation that spending by large technology companies on AI will keep demand for high speed optical components ahead of supply.

What Each Company Brings

Marvell supplies electrical and optical interconnect, network switching, custom AI processors and the chips that attach to them, along with advanced semiconductor process technology. Lumentum supplies high performance lasers, optical transceivers, optical circuit switching and specialized compound semiconductor manufacturing, including indium phosphide.

Together the companies expect a portfolio that spans leading edge CMOS, silicon photonics, compound semiconductors and advanced packaging. They say the combination should lift long term revenue growth and non GAAP gross and operating margins, provide line of sight to more than USD 1 billion in annual run rate cost synergies and add to Marvell's non GAAP earnings per share in the first year after closing.

Marvell's Climb and the Broadcom Contest

Three years ago Marvell was a relatively little known chipmaker. Its market value now exceeds USD 170 billion, built on helping large technology companies such as Amazon (NASDAQ:AMZN) develop custom AI chips and data center networking. Annual revenue grew from USD 3 billion in fiscal 2021 to USD 8.2 billion in fiscal 2026. Shares reached a record high in June after Nvidia (NASDAQ:NVDA) CEO Jensen Huang said the company could become the next trillion dollar company, and Nvidia invested USD 2 billion each in Marvell and Lumentum earlier this year.

Marvell's largest customer win came in August, when it signed an agreement to supply chips that sit alongside the AI processors of Google, a unit of Alphabet (NASDAQ:GOOGL). The agreement is worth up to USD 120 billion in sales through fiscal 2033 and gives Alphabet the right to buy a USD 12.2 billion stake. Broadcom has long been Google's main custom chip partner and sells a broader range of AI data center hardware under one roof. Marvell's USD 3.5 billion purchase of Celestial AI, which closed in February, had already expanded its photonics business.

Share Prices and the Chip Selloff

Since talks between the two companies were first reported in late October, Lumentum shares have fallen about 8% and Marvell shares about 22%. A broad chip selloff accelerated over that period after Intel (NASDAQ:INTC) issued a weak forecast.

Lumentum's Competitive Position

Lumentum competes with Coherent (NYSE:COHR) and China's Zhongji Innolight. It stands to benefit from a proposed US ban on new Chinese optical transceivers, which could shift demand toward domestic suppliers.

Leadership and Quarterly Results

Murphy will remain chairman and CEO of the combined company. Three Lumentum directors, including Hurlston, will join Marvell's seven member board.

Alongside the announcement, Marvell reported preliminary revenue for its fiscal third quarter of 2027, which ended October 31, 2026, in line with guidance. It kept the midpoint and narrowed the range to plus or minus 2% from plus or minus 5%. The figures are unaudited. Lumentum separately reported results for its first fiscal quarter of 2027. The companies held a joint call at 8:00 a.m. ET on Monday.

What to Watch as the Deal Heads Toward Closing

Items on the calendar include the SEC filing of the joint proxy statement and prospectus, stockholder votes at both companies, regulatory reviews, the movement of Marvell's share price against the fixed exchange ratio, and the status of the proposed US restrictions on Chinese optical transceivers.
