Marvell to Acquire Lumentum in $115B All-Stock Deal
Marvell Technology has agreed to acquire photonics specialist Lumentum in an all-stock transaction valued at $115 billion including debt, with an equity value of approximately $102.5 billion. This marks one of the largest tech deals, surpassing Microsoft's acquisition of Activision Blizzard and Dell's purchase of EMC. Lumentum shareholders will receive 4.5 Marvell shares per share, representing a 23.9% premium. The combined company aims to lead in AI connectivity, capitalizing on the shift from copper to optical interconnects in AI data centers, with co-packaged optics projected to expand the addressable market to $550 billion. Marvell expects over $1 billion in annual cost synergies and positive EPS contribution in the first year after closing. Both boards approved unanimously, with Marvell CEO Matt Murphy retaining his role and Lumentum CEO Michael Hurlston joining the board. The deal, expected to close in the first half of 2028, faces shareholder and antitrust approvals. Market reaction was skeptical, with shares of both companies falling. Nvidia, which invested $2 billion in each company in March 2026, shares circular dealmaking concerns. This follows Marvell's earlier acquisition of Celestial AI.
Major consolidation in AI infrastructure space, creating a category leader and impacting the entire AI connectivity ecosystem.
