Marvell to acquire Lumentum in $115 billion all‑stock deal

Marvell Technology announced an all‑stock acquisition of Lumentum Holdings, offering 4.5 Marvell shares for each Lumentum share. The transaction is valued at $115 billion, includes a 23.9% premium, and is expected to close in the first half of 2028 pending shareholder and regulatory approvals. Lumentum reported September‑quarter revenue of $1.26 billion, up 136.5% year‑over‑year, while Marvell’s stock fell more than 6% on the announcement.

The deal creates a large dilution exposure for Lumentum shareholders, as their value now moves with Marvell’s share price until closing. Marvell’s shares dropped over 6% on the news, reflecting market concerns about the size of the transaction and antitrust risk.
