Morgan Stanley: Marvell Technology, Inc. (MRVL.US)'s US$115 billion acquisition of Lumentum is expected to strengthen its AI optical communications advantage; the stock has been oversold by the market
Morgan Stanley's latest research report notes that Marvell Technology, Inc.'s approximately US$115 billion acquisition of optical communications equipment maker Lumentum is an aggressively priced deal with relatively high execution risk, but it is expected to help Marvell establish a stronger competitive advantage in the next-generation AI optical interconnect market.
Morgan Stanley: Marvell Technology, Inc. (MRVL.US)'s US$115 Billion Acquisition of Lumentum Expected to Strengthen Its AI Optical Communications Advantage; the Stock Has Been Oversold by the Market
Morgan Stanley's latest research report notes that Marvell Technology, Inc.'s (MRVL.US) acquisition of optical communications equipment maker Lumentum (LITE.US) for approximately US$115 billion is a transaction with aggressive pricing and high execution risk, but it is expected to help Marvell establish a stronger competitive advantage in the next-generation artificial intelligence (AI) optical interconnect market. Given Marvell's strong track record of successfully integrating multiple technology companies, Morgan Stanley believes the market's negative reaction to the deal may be excessive.
Under the definitive agreement announced by both parties on November 2, Marvell will acquire Lumentum in an all-stock transaction, with Lumentum shareholders receiving 4.5 Marvell shares for each Lumentum share they hold. The transaction corresponds to an enterprise value of approximately US$115 billion, equivalent to about US$1,132 per Lumentum share, a 23.9% premium to the October 28 closing price unaffected by the deal news.
Upon completion of the transaction, existing Marvell shareholders will hold approximately 67% of the combined company, while Lumentum shareholders will hold approximately 33%. The transaction is expected to close in the first half of 2028, subject to approval by both companies' shareholders and relevant regulatory authorities.
Morgan Stanley notes that this is the largest semiconductor industry acquisition ever agreed, more than 10 times the size of Marvell's previous acquisition of Inphi. Despite the high acquisition price, the technical integration logic behind it is worth attention.
AI Optical Communications Technology Integration Becomes Core Logic of the Acquisition
Morgan Stanley believes that as AI data centers continue to expand in scale, optical communications technology is gradually transforming from a traditional data transmission component into critical infrastructure that determines computing system performance. Marvell has advantages in digital signal processors (DSPs), network switching chips and custom chips, while Lumentum possesses difficult-to-replicate indium phosphide (InP) laser manufacturing capabilities, optical switching technology and related production capacity.
By integrating the two companies' technologies, the new company is expected to jointly design laser light sources, optical engines and switching chips, thereby improving data transmission performance, shortening product validation cycles and increasing the product value per optical connection.
Morgan Stanley notes that in next-generation AI computing systems, customers are increasingly inclined to purchase highly integrated optical communications solutions from a single supplier. Compared with simply establishing a partnership, directly acquiring Lumentum can also help Marvell secure capacity for key lasers that are currently in tight supply.
Lumentum holds leading positions in multiple segments, including 200G EML lasers used in high-speed optical modules, pump lasers and optical circuit switching (OCS) equipment. Among these, the company's share of the pump laser market reaches 70% to 80%.
In addition, Lumentum is an important participant in NVIDIA Corporation's (NVDA.US) optical communications supply chain. Morgan Stanley's research report notes that NVIDIA Corporation previously invested US$2 billion in Lumentum and made multi-billion-dollar purchase commitments, further highlighting the strategic value of its optical technology.
Lumentum's Strong Results with AI Optical Communications Orders Continuing to Grow
It is worth noting that at the time of the acquisition announcement, Lumentum's latest quarterly results also showed strong AI demand. According to Morgan Stanley's research report, Lumentum reported fiscal 2027 first-quarter revenue of US$1.263 billion, up 25.5% quarter-over-quarter and slightly above the market consensus.
Profitability was even more outstanding. Non-GAAP gross margin for the quarter reached 53.2%, about 1.7 percentage points above market expectations; non-GAAP operating margin reached 42.3%, about 2.5 percentage points above market expectations. Non-GAAP earnings per share reached US$4.57, about 9% above the market consensus and also exceeding the US$4.40 to US$4.45 previously expected by buy-side investors.
More importantly, Lumentum announced it had won a second large near-package optics (NPO) and co-packaged optics (CPO) project order, with related purchase commitments exceeding US$5 billion, expected to begin shipping in the second half of 2027.
The company also noted that pump lasers and optical circuit switching equipment are the main drivers of current business growth. As the demand outlook for OCS becomes clearer, this business is expected to grow into a multi-billion-dollar annual revenue business in the future.
For the fiscal 2027 second quarter, Lumentum provided revenue guidance of approximately US$1.6 billion, about 7% above the market consensus; non-GAAP earnings per share guidance of approximately US$6.05, about 19% above market expectations.
The company expects non-GAAP operating margin to rise further to 45% to 46% in the next quarter, indicating that business scale expansion is continuing to drive profitability improvement.
Over US$1 Billion in Annual Cost Savings Expected, but High Valuation Means Limited Room for Error
According to Marvell management's expectations, the combined company can achieve more than US$1 billion in sustained cost synergies annually, mainly from product cost optimization and supply chain integration. Both parties also expect the transaction to be accretive to the combined company's non-GAAP earnings per share in the first year after closing.
Morgan Stanley's analysis suggests that these cost savings mainly come from integrating both parties' existing products into each other's solutions and reducing reliance on third-party suppliers. However, since Lumentum is already an important customer of Marvell, some of the two parties' existing intercompany transactions will be eliminated after the merger, so the actual synergy benefits will still depend on subsequent product integration and market expansion.
According to Morgan Stanley's pro forma estimates, the combined company's 2029 revenue is expected to reach approximately US$71 billion, with non-GAAP gross margin of 57.8%, operating margin of 46.8% and non-GAAP earnings per share of US$20.27.
This EPS forecast is about 3% above the 2029 market consensus of US$19.76. However, Morgan Stanley emphasizes that since the transaction is not expected to close until 2028, the related forecasts still carry considerable uncertainty.
At the same time, the US$115 billion transaction valuation has also raised Morgan Stanley's concerns about the acquisition cost. Annualizing Lumentum's current quarterly revenue, the enterprise value Marvell is paying is approximately 22 times its revenue; calculated on fiscal 2026 revenue, the valuation reaches approximately 38 times.
Morgan Stanley notes that historically, valuations for optical communications industry acquisitions have typically been about 2 to 11 times trailing 12-month revenue. Although Lumentum's AI business growth prospects and scarce capacity can support a certain premium, such a high price means there is very little room for error in the transaction.
Morgan Stanley: Integration Risk Cannot Be Ignored, but Marvell's Stock Has Been Oversold
Morgan Stanley believes one of the main risks facing the acquisition is that Lumentum's current high margins may be difficult to sustain over the long term. Due to tight supply of indium phosphide lasers, Lumentum's current profitability is already above its previously set long-term targets. If industry capacity increases, competition intensifies, or AI infrastructure investment slows in the future, its product prices and margins could come under pressure.
Another risk comes from customer relationships. Marvell currently supplies DSP chips to multiple optical module manufacturers, some of which are precisely Lumentum's competitors. After the acquisition is completed, these customers may worry that Marvell will lose its neutrality as an independent chip supplier and turn to other suppliers. In addition, Lumentum's manufacturing business is more capital-intensive than Marvell's, which could also increase the combined company's fixed costs and operating cycle risk.
However, Morgan Stanley emphasizes that Marvell has a good historical track record in M&A integration. Its previous acquisitions of Cavium, Inphi and Avera all exceeded original revenue and cost synergy targets. Among them, the Inphi business is expected to grow more than 10 times since being acquired.
Morgan Stanley believes these successful experiences provide some confidence for Marvell's large-scale acquisition this time, although the US$115 billion transaction size means management will face integration challenges far greater than before.
The firm notes that the acquisition is strategically reasonable but financially demanding. Whether it succeeds in the future will depend on whether the two parties can translate their technological advantages in AI optical communications into sustainable high-margin growth while avoiding Marvell's loss of existing DSP customers.
Overall, Morgan Stanley believes that although the transaction carries substantial execution risk, Marvell's stock selloff after the news was announced was excessive. As of the November 2 close, Marvell's stock price was US$171.41. Morgan Stanley maintains its "Equal-weight" rating with a price target of US$300; it also maintains its "Equal-weight" rating on Lumentum with a price target of US$1,000.
