The $80 billion figure in some headlines reflects an equity-value framing, while Lumentum's equity value is reported at about $102.5 billion. The deal still requires U.S. and other regulatory clearance. Termination fees are $5.8 billion payable by Marvell and $2.9 billion payable by Lumentum in certain circumstances. Marvell would owe $3.2 billion if regulators block the deal. Nvidia is a backer of both companies. It invested $2 billion in Lumentum earlier in 2026 under a multi-year laser purchase agreement, and in March it put $2 billion into Marvell. Google holds rights to acquire a $12.2 billion stake in Marvell under a separate agreement. Those arrangements are not yet tied publicly to the deal's terms.
Marvell designs custom chips but does not make the indium phosphide lasers it needs, and it already buys them from Lumentum. Bloomberg first reported in late October that the companies were in advanced talks. This is Marvell's largest deal since its $10 billion Inphi acquisition in 2021, and it follows the $5.5 billion purchase of photonics startup Celestial AI. Investors pushed back. Marvell shares fell more than 10% and Lumentum shares fell about 15% on the announcement, with concern focused on the price and the dilution from an all-stock structure. Some analysts asked whether the deal signals peak AI-infrastructure enthusiasm.
For attorneys, the near-term watch items are the U.S. antitrust review and any other foreign clearances, since the $3.2 billion reverse termination fee makes a regulatory block costly for Marvell. Track the shareholder votes on both sides, the Nvidia and Google stake arrangements, and whether the combined company's position against Broadcom draws scrutiny in the review. Closing is not expected until the first half of 2028, so most of the work ahead is regulatory and documentary.
