Key Points:
- Rothschild identified Lumentum, Coherent, Celestica, and Credo as the absolute best hardware stocks for the artificial intelligence boom.
- Nvidia poured exactly $2 billion into both Lumentum and Coherent to help them build more laser components and optical transceivers.
- Celestica grew its revenue by more than 50% as giant technology companies bought millions of its custom Ethernet switches.
- Credo recently signed a deal to acquire DustPhotonics to improve its silicon technology and secure better price targets from major banks.
Financial firm Rothschild just released a new list of the most valuable stocks in the artificial intelligence networking sector. The firm highlighted four specific companies that stand ready to make massive profits from the global surge in high-speed data transmission. As technology giants race to build faster computers, these four networking companies provide the essential hardware to connect everything.
The networking sector builds the physical backbone of the artificial intelligence revolution. These companies manufacture critical hardware for data centers, including laser systems, Ethernet switching equipment, and optical transceivers. When people use artificial intelligence applications, massive amounts of data must travel between computer servers almost instantly. This rapid data flow requires specialized physical components that only a few companies can build effectively.
Lumentum takes the first spot on the Rothschild list. The company focuses heavily on manufacturing laser components and finished optical transceivers. Customer demand for these parts skyrocketed recently. To keep up with orders, Lumentum plans to increase its manufacturing capacity by 80% over the next 18 months. The company expects this massive expansion to drive significant revenue growth in the near future.
A massive cash injection from Nvidia made this aggressive expansion possible. Nvidia recently made a $2 billion investment in Lumentum to ensure the company can supply enough parts for future data centers. This financial backing already shows positive results. Lumentum recently reported third-quarter earnings and revenue numbers that easily beat Wall Street expectations. Following that strong earnings report, analysts at BofA Securities raised their price target on the stock, pointing to a much better profit margin outlook.
Coherent claimed the second spot on the list. Just like Lumentum, Coherent holds a very strong position in the optical transceiver market. The company also generates significant revenue from other specialized optical technologies. In a striking similarity to its rival, Coherent also received a massive $2 billion investment directly from Nvidia to boost its manufacturing capabilities.
Coherent continues to push the boundaries of hardware engineering. The company recently announced major advancements in its silicon carbide technology, which helps power-hungry artificial intelligence data centers run much more efficiently. Financial analysts love these new developments. Stifel recently increased its price target for Coherent stock, while Rothschild Redburn officially initiated coverage with a solid Buy rating.
Celestica secured the third position thanks to its incredible financial growth. The company currently sees its revenues growing at over 50%. This massive jump comes directly from its rising market share in customized Ethernet switching hardware. Major technology companies plan to increase their capital expenditure spending significantly throughout the 2026 fiscal year. Celestica will capture a large portion of that new spending.
The company recently proved its market dominance by winning a massive contract. A major tech giant hired Celestica to provide its new 1.6Tbps Ethernet switch. The company also announced that these incredibly fast artificial intelligence data center switches are finally available for general order. Because of this strong product lineup, several major financial firms, including Aletheia Capital and CIBC, confidently raised their price targets on Celestica stock.
Credo rounds out the Rothschild list in the fourth spot. Credo’s core business involves supplying active electrical cables to data centers. Some Wall Street analysts worried that newer technologies might replace these cables and hurt the company. However, Rothschild strongly disagrees with that negative outlook. The firm believes the market took a completely wrong view of how future technological shifts will actually impact Credo’s total revenue.
Credo management also refuses to sit still. The technology group recently signed a major agreement to acquire DustPhotonics, a startup that develops advanced silicon photonics technology. This smart acquisition shows that Credo plans to adapt and grow its product offerings. Following the acquisition news, analysts at both Jefferies and Mizuho raised their official price targets on Credo stock.
These four rankings reflect Rothschild’s view of the expanding infrastructure market. The firm placed the most emphasis on companies that successfully secure major outside investments and aggressively expand their physical factory capacity. As the artificial intelligence industry continues to grow, Lumentum, Coherent, Celestica, and Credo are well positioned to supply the physical hardware that enables digital software.
