The merger would join custom AI chips with optical components; both shares fell as chip stocks sold off Monday.

Marvell Technology said on Monday it will acquire optical components maker Lumentum Holdings in an all-stock transaction valued at about $115 billion, one of the largest semiconductor-sector deals on record and a bet that optical connections will be central to artificial intelligence data centers [1][2].
Under the terms announced by Marvell, each Lumentum share will convert into 4.5 Marvell shares, or about $1,132 per Lumentum share. That represents a premium of roughly 23.9% to Lumentum's October 28 close, the last trading day before reports of deal talks surfaced [1]. After closing, current Marvell holders would own about 67% of the combined company on a fully diluted basis and Lumentum holders about 33% [1].
Marvell Chairman and Chief Executive Matt Murphy would continue to lead the company, and three Lumentum directors, including Lumentum CEO Michael Hurlston, would join Marvell's seven-member board [1]. Both boards approved the agreement unanimously [2]. The companies expect the transaction to close in the first half of calendar 2028, subject to shareholder and regulatory approvals [1].
Management said it sees a path to more than $1 billion in annual run-rate cost synergies and expects the deal to add to Marvell's non-GAAP earnings per share in the first year after closing [1]. Hurlston said in the release that joining Marvell positions the combined company for a market opportunity of $550 billion [1].
Lumentum released results alongside the announcement. For its fiscal first quarter, the company reported adjusted earnings of $4.57 a share on revenue of $1.26 billion, compared with $1.10 and $533.8 million a year earlier. Adjusted gross margin rose to 53.2% from 39.4%. It guided fiscal second-quarter revenue to $1.575 billion to $1.625 billion, above the $1.48 billion consensus cited by Yahoo Finance [2]. Marvell separately said preliminary fiscal third-quarter revenue is consistent with prior guidance [2].
Markets did not greet the deal warmly. Reuters reported that Marvell shares tumbled on Monday and Lumentum also fell, in a session when chip stocks led a broader technology decline [3]. Yahoo Finance noted that both stocks had traded higher in pre-market trading before halts in the shares ahead of the announcement [2]. The Nasdaq Composite closed down 1.07% at 25,164.32, with the technology sector weak after the index lost more than 5% in October amid concern that AI spending is outpacing near-term cash generation [3][4].
The structure matters for investors. Because the consideration is entirely stock, Marvell is not taking on new financing, but its shareholders accept dilution of about one-third of the combined company, and the fixed exchange ratio means the deal's dollar value will move with Marvell's share price until closing [1].
What to watch next: the regulatory path, given the long timeline to 2028 and the strategic importance of AI networking components; whether rival chip and optical suppliers respond with deals of their own; and how analysts weigh the cost savings against the dilution. Advanced Micro Devices reports after the close Tuesday, which will offer another read on AI chip demand [3].
