Marvell Technology is betting $115 billion, announcing that it will bring Lumentum under its wing, moving from selling chips to an integrated "chip + optics" model. However, whether the acquisition price is too high, whether it will "steal business" from optical module manufacturers that buy its chips, and an approval period lasting more than a year all add uncertainty to this "blockbuster purchase."

On November 2 local time, U.S. chip design company Marvell Technology and optical communications component manufacturer Lumentum announced that they had reached a definitive agreement under which Marvell Technology will acquire the latter in an all-stock transaction, with an implied enterprise value of approximately $115 billion.

Under the agreement, each Lumentum shareholder will receive 4.5 shares of Marvell Technology common stock for each share held. Based on the closing prices of the two companies on October 28, before the acquisition rumors surfaced, this equates to about $1,132 per share, a premium of about 23.9% over Lumentum's closing price that day.

After the transaction is completed, existing Marvell Technology shareholders will hold about 67% of the combined company, and Lumentum shareholders about 33%, with Marvell Technology Chairman and CEO Matt Murphy continuing to lead.

According to media reports, excluding the merger of SpaceX and xAI, this is the largest M&A deal in global tech industry history by equity value. However, the transaction still requires approval from both companies' shareholders and regulators, and is expected to be completed only in the first half of 2028.

Meanwhile, media cited regulatory filings reporting that if the transaction is blocked by regulators, Marvell Technology will need to pay Lumentum a $3.2 billion termination fee; if Marvell Technology's board withdraws support or instead accepts another acquisition offer, it will need to pay $5.8 billion, while Lumentum would need to pay $2.9 billion in comparable circumstances.

Axel Rudolph, chief technical analyst at UK online trading platform IG Group, said after the deal was announced that combining Marvell Technology's custom chips and networking technology with Lumentum's optical components could put the company in a stronger position to benefit from data center demand for faster, more energy-efficient connections.

But he also said bluntly that this is a huge gamble, and investors have reason to ask whether Marvell Technology is paying too high a price and taking on too many businesses at once.

As of press time, Lumentum shares were down about 9.5%, and Marvell Technology about 5%. Since the acquisition rumors surfaced, both companies' shares have fallen sharply, weighed down by concerns about an AI bubble.

Adding "a beam of light"

As AI clusters grow larger, data flows ceaselessly between chips, racks and even data centers. Matt Murphy noted at an earnings call in August this year that the limitations of copper cables in transmission distance and bandwidth are pushing customers toward optical interconnects.

At its October investor day, Marvell Technology projected revenue of $70 billion to $90 billion in fiscal 2031, of which about $37.5 billion would come from interconnect business. The company expects the interconnect market to grow 65% annually, reaching $65 billion by 2030.

In optical modules, the core component of optical interconnects, lasers convert electrical signals into light, while DSP chips (digital signal processing chips) process and calibrate signals. Lumentum is an important supplier of lasers, and Marvell Technology is a major supplier of DSP chips for optical modules; the former already supplied lasers to the latter, and now the two sides are about to become "one family."

According to the two companies' plans, the combined company will integrate chips with lasers, optical modules and optical switching technology, with the target market expected to expand to $550 billion. The two companies expect the merger to achieve more than $1 billion in annual cost synergies and to be accretive to Marvell Technology's non-GAAP earnings per share in the first year after the transaction closes.

Andrew Schmitt, founder and chief analyst at optical communications market research firm Cignal AI, said during the rumor stage that the core logic of the deal is vertical integration, not gaining more laser capacity.

In his view, Marvell Technology already has solid relationships with multiple laser suppliers, and the significance of the acquisition lies in enabling co-design of chips and optical components and offering customers more complete systems.

Such integration also moves Marvell Technology closer to the business model of longtime rival and chip giant Broadcom. Karl Ackerman, an analyst at European investment bank BNP Paribas, previously said that Broadcom is currently the only company with compute chips, switch chips and its own laser product line at the same time, and that acquiring Lumentum could help Marvell Technology build similar vertical integration capabilities.

Looking at the evolution of technology routes, this acquisition may have a deeper consideration. The industry is advancing co-packaged optics (CPO), which places optical components directly next to switch chips or compute chips, greatly reducing or even eliminating the DSP chips in traditional optical modules.

Gareth Owen, associate director at market research firm Counterpoint Research, noted in a report released in late October that as data center networks evolve toward CPO, demand for Marvell Technology's DSP chips could weaken, while lasers remain indispensable regardless of how the technology changes. In his view, acquiring Lumentum amounts to Marvell Technology hedging against this shift in advance.

According to media reports on October 29 local time, Lumentum management said the industry is moving toward volume production of near-packaged optics and co-packaged optics around 2028. That roughly coincides with the expected completion time of the acquisition.

Applause and doubts

According to media reports on October 30 local time, U.S. brokerage Rosenblatt believes that with chips, DSP, optical components and optical switching capabilities all in place, Marvell Technology will gain a major competitive advantage in the high-speed optical module and CPO markets. William Kerwin, an analyst at investment research firm Morningstar, likewise believes the deal makes strategic sense.

Cignal AI founder Schmitt offered a profit-based reason for support. In his view, by packaging chips and optical components into complete systems for sale, Marvell Technology's total gross profit could exceed that from selling components separately.

Compared with recognition at the strategic level, market concerns about the cost of the deal cannot be ignored either. Even before the deal terms were announced, Kerwin, while affirming the deal logic, said bluntly that based on Lumentum's valuation level at the time, the acquisition looked financially expensive.

U.S. investment bank Stifel also projected during the same period that after incorporating Lumentum, Marvell Technology's overall gross margin would be diluted in the early stages of the transaction, and would then gradually recover to the company's original level as system-level products scale up.

Another concern brought by the transaction lies in customer relationships: Marvell Technology's DSP chips are currently widely sold to optical module manufacturers, and Lumentum itself also produces optical modules. After the merger, with Marvell Technology selling chips on one hand and making modules on the other, it could compete head-on with optical module manufacturers that buy its DSP chips.

Counterpoint Research associate director Owen believes some optical module manufacturers may therefore turn to other suppliers such as Broadcom or high-speed interconnect chip maker Credo. Even Schmitt, who is optimistic about the deal, cautioned that Marvell Technology must convince existing DSP customers and Lumentum's optical component customers that existing supply relationships will not be affected.

From signing to the expected completion of the transaction in the first half of 2028, there is still more than a year of review and waiting. Whether this "beam of light" can smoothly shine into Marvell Technology remains to be answered by time.
