Marvell Reportedly in Advanced Talks to Acquire Lumentum in Major AI Optics Deal

Marvell Technology is reportedly in advanced talks to acquire Lumentum Holdings, a maker of data-center optical components used in AI build-outs, according to people familiar with the matter cited by Bloomberg and relayed by Digitimes. No agreement has been signed, and neither company has publicly confirmed the talks.

What's being reported

The report, which emerged late on October 28, 2026, describes Marvell and Lumentum as being in advanced discussions over a potential acquisition, according to 247wallst.com, which cited both Bloomberg and a Reuters source in its account. Sources differ on which outlet's reporters first broke the story, with some accounts attributing the initial report to Bloomberg and others to Reuters, but the substance is consistent: people familiar with the matter say the two companies are discussing a deal that could reshape the supply chain for AI data-center optics.

Importantly, this remains a reported deal rather than a confirmed one. As 247wallst.com noted, "nothing has been signed or announced," and the companies "have yet to disclose a price, a per-share offer or a structure." The outlet also pointed out that no press release, SEC Form 8-K, or board statement has surfaced confirming the talks. According to 247wallst.com, Reuters' requests for comment went unanswered by both companies, while TradingView, relaying the same Bloomberg report, said representatives for Marvell and Lumentum could not immediately be reached for comment.

According to the Bloomberg report cited by TradingView, a deal could be announced "as soon as next week" following the October 28 report, though that timeline has not been confirmed by either company.

Deal size and financing questions

The scale of a potential transaction is notable. Lumentum's market capitalization stood at roughly $83 billion, while Marvell's was valued at about $221 billion, according to data reported by TradingView. On those two reported figures, Lumentum sits about $138 billion below Marvell (83 − 221), or roughly 62.4% smaller in relative terms ((83 − 221) ÷ 221 × 100). That is straightforward arithmetic rather than a forecast, but it frames the financing challenge a full acquisition would represent.

247wallst.com reported that Marvell had about $3.92 billion in cash on hand, and cited Bernstein analysts as saying a deal of Lumentum's size would likely require additional financing and could prove difficult to integrate. Separately, Yahoo Finance reported that Marvell's management has targeted a non-GAAP operating margin range of 38% to 40% while growing its custom products business, and noted that funding and integrating an optics business using a $3 billion revolver would test that margin discipline if product mix or execution falters. No specific price, exchange ratio, or deal structure has been disclosed by either company.

Market reaction

Investors reacted quickly once the report surfaced. In premarket trading on October 29, Marvell shares fell about 11% to $222.81, while Lumentum shares rose about 5% to $961.90, according to data reported by 247wallst.com. Coherent, described as the other major optical supplier, slipped about 1% before the open, the same report noted. Both Marvell and Lumentum had already posted large year-to-date gains heading into the report, up 163% and 161% respectively, according to 247wallst.com — a 2-percentage-point gap (163 − 161), or about 1.2% in relative terms ((163 − 161) ÷ 161 × 100). Read as interpretation of those reported figures, both stocks had already priced in substantial optimism about AI-driven demand before this report emerged.

Strategic context: the shift from copper to optics

The reported talks arrive amid a broader industry conversation about how AI data centers will handle rising bandwidth demands. On Marvell's August 27 earnings call, then-CEO Matt Murphy said "the reach and bandwidth limitations of copper are increasingly driving customers towards optical interconnects," according to 247wallst.com. Murphy also cautioned that the shift from copper to optics "is expected to take several years, with both technologies coexisting," suggesting the transition is gradual rather than abrupt.

Lumentum's own business reflects surging near-term demand: the company's quarterly revenue reached $1.01 billion, up 109.3%, according to 247wallst.com. Lumentum's Wupen Yuen pointed to "broad momentum toward a 2028 ramp of NPO and CPO" - near-packaged and co-packaged optics, which position the light source directly next to the chip - as the next phase of this transition, per the same report.

If completed, a Lumentum acquisition would fold an optical-components maker directly into Marvell's operations. Yahoo Finance's analysis suggested this would concentrate more of the high-speed optical link budget around a single vendor, potentially deepening Marvell's role in wiring up hyperscaler AI clusters relative to peers like Broadcom and Nvidia. That framing is attributed analysis rather than a confirmed competitive outcome, since the deal itself remains unconfirmed by either company.

What comes next

With no signed agreement, 8-K filing, or official statement from either company as of this reporting, the timeline remains uncertain. One commentator at 247wallst.com suggested that if a signed agreement and accompanying SEC filing do not appear by November 13, 2026, the market's early optimism around Lumentum's share gain should be viewed with skepticism. That is one analyst's framing of a benchmark, not a confirmed deadline from either company, and readers should treat it as such.

Bottom Line

Multiple outlets, citing people familiar with the matter, report that Marvell and Lumentum are in advanced talks over a potential acquisition tied to AI data-center optics. Neither company has confirmed the talks publicly, and no price or structure has been disclosed. Marvell's roughly $3.92 billion in cash against Lumentum's roughly $83 billion valuation points to significant financing questions if a deal proceeds — Bernstein analysts, cited by 247wallst.com, said a transaction that size would likely need additional financing and could be hard to integrate. Markets reacted sharply to the report, but until a formal agreement or regulatory filing appears, the transaction remains unconfirmed.
