Marvell agrees to buy Lumentum in a $115 billion all-stock deal to join chips and optics

Marvell Technology (Nasdaq: MRVL) agreed on November 2 to acquire Lumentum (Nasdaq: LITE) in an all-stock deal that values Lumentum at an implied $115 billion, according to a joint press release filed with the SEC. Lumentum holders will receive 4.500 Marvell shares for each Lumentum share.

An exchange ratio fixed at 4.500 Marvell shares

The companies said the exchange ratio is fixed and that the price works out to about $1,132 per Lumentum share. That is a premium of about 23.9% to each company's closing share price on October 28, the last trading day before what the release calls market speculation about a deal began. The release describes the deal as all-stock and does not mention separate financing.

Once the deal closes, current Marvell stockholders would own about 67% of the combined company and Lumentum stockholders about 33%, on a fully diluted basis. Both boards approved the agreement unanimously.

What each side brings

Marvell, the release says, contributes electrical and optical interconnect, network switching, custom chips and advanced semiconductor technology. Lumentum contributes high-performance lasers, optical transceivers, optical circuit switching and compound semiconductor manufacturing, including indium phosphide.

Matt Murphy, Marvell's chairman and chief executive, said "AI infrastructure is undergoing a fundamental architectural shift toward optical connectivity, creating an opportunity that comes along once in a generation." Michael Hurlston, Lumentum's president and chief executive, said the combination puts the company in a position "to capitalize on a market opportunity of $550 billion."

The companies said they expect the combined business to address a total market of $550 billion and see "line of sight to more than $1 billion in annual run-rate cost synergies." They also said they expect the deal to add to Marvell's non-GAAP earnings per share in the first year after closing. These are the companies' own projections.

Leadership and the road to closing

Murphy will remain chairman and chief executive of the combined company. Three Lumentum directors, including Hurlston, will join Marvell's board, which has seven directors.

The companies expect closing in the first half of calendar year 2028. It requires approval from the stockholders of both companies and regulatory approvals, among other customary conditions. Marvell said it plans to file a registration statement on Form S-4 with the SEC that will include a joint proxy statement.

In the same announcement, Marvell said its preliminary revenue for the fiscal third quarter of 2027 is consistent with its prior guidance. It kept the midpoint and narrowed the expected range to plus or minus 2% from plus or minus 5%. Lumentum separately reported results for its fiscal first quarter of 2027.

The structure matters more than the $115 billion

We think the structure matters more than the headline value. The release mentions no separate financing, so the price is paid in Marvell shares, and its current owners give up about a third of the combined company. The threat is the long gap to a closing expected in the first half of 2028: two years in which AI hardware demand, regulators and the stock prices behind a fixed exchange ratio can all change.

The opportunity is the one the companies describe: lasers and chips designed together for data-center links. We expect the deal's merit to show in whether the $1 billion of cost savings and the accretion promise survive the filing of the S-4, which should give more detail. Our view would change if regulators impose conditions on the optical business or if either stockholder vote fails.
