Marvell shares tumble as Lumentum soars on report of advanced buyout talks
Bloomberg reported this week that the chipmaker is in advanced negotiations to acquire optical-networking supplier Lumentum Holdings, an unconfirmed deal that sent both stocks swinging and revived questions about Marvell's appetite for debt-funded acquisitions.

Marvell Technology is in advanced negotiations to acquire optical-networking supplier Lumentum Holdings, according to a Bloomberg report that circulated Wednesday evening, in a potential deal that would pair two of the chip industry's key suppliers to the artificial-intelligence data-center boom. Neither company has confirmed a transaction, and the report cautioned that terms and timing "remain subject to change."
The report, which cited people familiar with the matter, said a deal could be announced "as early as next week." Trading in both stocks moved sharply within minutes: shares of Lumentum jumped as much as 17% in after-hours trading in the United States, while Marvell fell roughly 8%, according to the Bloomberg-sourced account carried by Phemex News and corroborated by a separate Newsquawk headline alert timestamped the same evening.
A credit line widened days before the news broke
The reported approach landed on a balance sheet that was already being reshaped for a large purchase. Six days before the Lumentum report surfaced, Marvell disclosed in a filing with the Securities and Exchange Commission that it had torn up its old $1.5 billion revolving credit facility and replaced it with a new one of up to $3 billion, with an option to expand commitments by a further $2 billion. The Form 8-K filed Oct. 22 shows Bank of America acting as administrative agent on the five-year facility, and it contains a telling covenant: Marvell's maximum leverage ratio, normally capped at 4.00-to-1, is permitted to rise to 4.50-to-1 for the fiscal quarter in which it completes an acquisition of at least $500 million, and for the three quarters that follow. Reports pegged Lumentum's market value at roughly $83 billion against Marvell's own $221 billion at the time, scale that would make it by far the largest transaction the chipmaker has attempted.
Marvell's acquisition run
Lumentum, if a deal materializes, would be the latest in a string of purchases Marvell has made this year as it builds out components for AI data-center networking. The company's own annual report filed with the SEC discloses that it closed two acquisitions in early February: Celestial AI, a maker of "Photonic Fabric" interconnect technology, for about $1.3 billion in cash and roughly 24.5 million shares; and XConn Technologies, a PCIe and CXL switching-silicon specialist, for about $280 million in cash and 2.1 million shares. Both deals pushed Marvell deeper into the business of moving data between AI chips at high speed — the same niche Lumentum occupies with its lasers and optical components.
The two companies are not strangers. They have jointly demonstrated optical-interconnect technology at industry trade shows, and both became beneficiaries of Nvidia's push to lock down its supply chain this year: Nvidia was reported to have made roughly $2 billion strategic investments in each company within weeks of one another in March. Lumentum is led by chief executive Michael Hurlston; Marvell has been run by chairman and chief executive Matt Murphy since 2016. Neither executive has commented publicly on the talks, and as of this writing, neither company's own newsroom — Marvell's investor-relations site or Lumentum's press-release page — carries any statement referencing the other company or an acquisition.
A deal built on an already leveraged balance sheet
Wall Street's reaction split sharply along strategic and financial lines. Analysts who cover both stocks have noted that Lumentum's optical franchise sits in a logical spot between compute silicon and networking gear — precisely where Marvell has been trying to expand — and that the two businesses have little horizontal overlap, which would limit antitrust risk if a deal is reached. But the same analysts flagged financing as the open question, pointing to a company that has now struck three sizable, partly debt- and stock-funded acquisitions inside a single calendar year.
For shareholders of both companies, the stakes are immediate: Lumentum holders saw a one-day paper gain that a confirmed deal would need to justify through an actual offer price, while Marvell holders absorbed a sell-off reflecting worry about dilution and debt capacity rather than doubts about the strategic logic.
What happens next
Because the report describes talks that are advanced but not final, the most immediate next step is confirmation one way or the other. If the companies follow the timeline described in the initial report, an announcement — likely in the form of a definitive merger agreement disclosed through SEC filings from both companies — could come within days. Absent that, investors are likely to watch for any trading halt, regulatory filing, or on-the-record statement from Marvell or Lumentum, none of which had appeared through Friday.
