Marvell Stock Dips As The Chip Firm Wagers $115 Billion On The Ai Data-center Boom

• Shares of Marvell Technology dropped after it announced a deal to buy Lumentum.
• Marvell said it would buy the photonics technology maker in a deal worth $115 billion.
• Investors have grown skittish about the AI trade lately, with tech stocks tanking late last week.

Marvell Technology shares are dropping to start the week after it announced a major bet on the AI infrastructure boom.

The US chip-tech maker said it would buy Lumentum Holdings, a producer of photonics technology for data centers, in an all-stock deal worth $115 billion. Marvell stock dropped as much as 7% after the announcement. Lumentum shares fell 12%.

Marvell's deal with Lumentum would mark a tie-up of two major AI hardware makers. It also comes at a time when investors are growing skittish about what the future may hold for the AI trade, and about the fragile economics of the data center boom in particular.

"While a coming together of Marvell and Lumentum may make business sense, the question as to whether it makes financial sense will hinge on how much Marvell management is willing to pay measured against the incremental revenue and profit to be had plus any incremental synergies," wrote Chris Versace, lead portfolio manager at TheStreet Pro.

Versace also highlighted last week's bruising tech sell-off. Marvell dropped 10% on Friday as the rest of the market swooned, with the shares extending losses on Monday even as the broader indexes recovered.

Other finance pros have raised questions regarding the data center buildout, even before the market's response to the Marvell-Lumentum deal. Earlier in October, analysts at Bernstein Research reported, after analyzing thousands of planned data center projects, that only 35% of currently planned capacity is likely to be completed.

Meanwhile, some investors are bracing for the impact of the midterm elections. If the anticipated Democrats tip the balance of power in Washington, it could lead to heightened scrutiny and pressure on data center builders, who have found themselves at the center of political backlash from local communities during the campaign season. Analysts at Morgan Stanley have noted that such a scenario could be a risk for the AI trade.

"Despite constructive commentary on AI demand, the market reaction has been starkly different, with semis and AI infrastructure continuing to sell off (the SOXX index fell 17% in October and is down 28% from its June high)," noted William Blair analyst Sebastien Naji in a note to investors on Monday.

Now, Marvell's deal with Lumenum is helping shine a light on investor concerns about the continued strength of the data center expansion. The dust is still settling from the strong sell-off around top AI names on Friday, with improved sentiment failing to lift Marvell stock as investors assess its latest bet on the data center
