Why Lasers for AI Matter to Data Centers

Lumentum manufactures lasers and optical parts that transmit massive amounts of data at high speed across communication networks1

. AI data centers increasingly rely on optical links instead of copper wires to connect growing clusters of processors, making these components critical for AI infrastructure1

1

. Lumentum chief executive Michael Hurlston revealed this month that the company's optical components for data centers are sold out through early 20291

1

. He noted the company will be unable to meet approximately 70% of demand for some products next year due to supply constraints1

1

. To address this shortage, Lumentum plans to invest at least $350m in Japan to manufacture more indium phosphide components1

Strategic Fit for Custom AI Chips and Networking

Marvell Technology already purchases lasers from Lumentum and has positioned itself as a major beneficiary of AI-related spending1

. The chipmaker produces custom AI chips and networking chips, collaborating with Amazon Web Services and Microsoft on their proprietary AI processors1

1

. In August, Marvell secured a chip deal with Google1

. Earlier this year, the company acquired Celestial AI for $3.5bn, which builds photonic technology for data transmission between processors1

. Marvell's stock has nearly tripled this year, and the company raised its fiscal year 2028 revenue forecast to $20bn from a previous estimate of $15bn, citing strong demand for networking products2

Investor Concerns Over Share Dilution

Market reaction to the merger talks revealed investor anxiety about the acquisition's structure. Lumentum shares jumped approximately 9% in after-hours trading, while Marvell's stock declined by more than 8% initially and fell as much as 14% in New York trading1

. Investors fear significant share dilution if Marvell Technology acquires Lumentum entirely through stock2

2

. Raymond James analysts noted that an all-share deal avoids interest costs and would dilute earnings less than debt financing, though Marvell shareholders would surrender more ownership1

1

. RBC Capital Markets analysts stated the deal "makes strategic sense given the highly complementary product portfolios," though they suggested the case strengthens if Marvell sells Lumentum's pluggable module business1

1

. Nvidia took a $2bn stake in Lumentum earlier this year in a deal that included collaboration on photonics, and holds approximately $99bn in shares of companies that purchase its chips1

1

. The Marvell Lumentum deal remains unfinalized, and the companies have not reached an agreement yet, with talks potentially ending without a transaction1
