Key Takeaways
- • Marvell Technology agreed to acquire optical components maker Lumentum in an all-stock deal valued at $115 billion including debt, announced Monday, November 2, 2026, one of the largest deals of 2026 according to Reuters.
- • Marvell will pay $1,132 per share in stock, a 23.9% premium to Lumentum's unaffected closing price on October 28, before deal talks were first reported, implying an equity value of $102.54 billion.
- • The combined company expects its total addressable market to expand to $550 billion, according to Marvell.
- • Lumentum is roughly half Marvell's size, and the acquisition is Marvell's largest since its $10 billion purchase of Inphi in 2021.
- • The transaction is a bet that Big Tech AI spending will sustain demand for high-speed optical components that are in short supply.
Summary
Marvell Technology is acquiring optical components maker Lumentum in a $115 billion all-stock transaction, including debt, according to Reuters. The deal, announced on Monday, positions the custom chipmaker to compete more directly with larger rival Broadcom, which has long served as Alphabet's Google's main custom-chip partner and offers customers a broader range of AI data center hardware. Marvell will pay $1,132 per share in stock, a 23.9% premium to Lumentum's last unaffected closing price on October 28, before talks were first reported. The implied equity value is $102.54 billion. Marvell said the combination would expand its total addressable market to $550 billion. Marvell shares rose 2.8% in premarket trading, while Lumentum shares were halted.
The acquisition reflects Marvell's strategy of building out its photonics business. Marvell closed a $3.5 billion purchase of Celestial AI in February, as rising use of AI agents and chatbots increases demand for faster optical links connecting thousands of chips in AI data centers. Lumentum competes with US-listed Coherent and China's Zhongji Innolight, and stands to benefit from a proposed US ban on new Chinese optical transceivers that could shift demand toward domestic suppliers. Nvidia invested $2 billion in each of Marvell and Lumentum earlier this year.
Marvell's market value has risen to more than $170 billion over roughly three years, driven by its work helping technology giants such as Amazon develop custom AI chips and networking technology. In August, Marvell signed a deal to supply chips alongside Google's AI processors worth up to $120 billion in sales through fiscal 2033, giving the search giant the right to buy a $12.2 billion stake. Nvidia CEO Jensen Huang has called Marvell the next "trillion-dollar company," and Marvell's annual revenue has more than doubled from $3 billion in fiscal 2021 to $8.2 billion in fiscal 2026.
The deal comes amid a broad chip selloff following Intel's weak forecast. Since the talks were first reported late last month, Lumentum's shares have fallen about 8% and Marvell's about 22%. Reuters notes that the transaction is one of the largest of 2026 and among the boldest corporate bets yet on an AI boom that chip executives expect to underpin industry demand for years.
