Marvell (MRVL) to Acquire Lumentum in $115 Billion AI Connectivity Deal

Marvell Technology announced a fixed-ratio deal to acquire optical components maker Lumentum, creating an "enormous" opportunity to serve AI infrastructure connectivity demands. The transaction values Lumentum at an implied $115 billion enterprise value, based on Marvell's share price. Under the agreement, Lumentum shareholders will receive 4.5 Marvell shares for each Lumentum share. The deal is expected to close in the first half of 2028.

Marvell's CEO highlighted the potential to combine electrical and optical technologies to meet shifting AI connectivity needs, referencing the exploding demand for such solutions. Marvell shares fell 8% and Lumentum's stock dropped 13% following the announcement, despite both companies having seen substantial stock gains during the AI boom the past year. Marvell more than doubled, and Lumentum quadrupled in stock price before Monday's decline.

This acquisition marks a major investment by Marvell in AI infrastructure, complementing its earlier multibillion-dollar purchase of Celestial AI, a startup focused on optical interconnectivity. The deal is positioned as a strategic response to increasing reliance on optical connections in AI chip operations. Marvell also confirmed support for Nvidia's role as the ecosystem leader in AI chip infrastructure, dismissing concerns about Nvidia's investments in related companies.

The deal’s completion will reshape AI connectivity infrastructure by integrating semiconductor and optical technologies at scale. For investors, the deal means Marvell’s share price will directly influence the value of the acquisition, and Marvell’s stock volatility around the closing date could impact shareholder returns.
