Deutsche Bank Shifts AI Strategy to Target Infrastructure Providers
Frankfurt, Wednesday, 2 September 2026.
Deutsche Bank is pivoting its AI investment strategy toward foundational optical and networking hardware. Notably, Nvidia has already backed this infrastructure transition by injecting $2 billion each into laser-technology specialists Lumentum and Coherent.
The Infrastructure Pivot
Deutsche Bank analysts argue that the initial phase of artificial intelligence deployment, focused heavily on compute power, is evolving into a connectivity story requiring robust physical infrastructure [1]. Gianmarco Conti, an analyst at the bank, emphasizes that while language models capture headlines, the indispensable elements in 2026 are the physical equipment connecting supercomputers [1]. This strategic shift suggests that capital should flow toward network and optical equipment suppliers rather than solely relying on software or processor giants [1]. The bank’s initiation note highlights that AI adoption is driving demand for computing capacity as both consumers and businesses increasingly utilize data-intensive digital services [2].
Consequently, the focus has moved to design connectivity and heat-management tools required to build out data centers [1]. Deutsche Bank prioritizes companies that address the energy crunch tied to servers, noting that thermal management is critical to prevent equipment choking [1]. This approach aims to capture value from the forced modernization cycle in corporate networks and the broader expansion of data center capabilities [1]. The analysis suggests that being an industry giant does not guarantee success, as seen with neutral ratings on certain large hardware distributors facing margin pressure [1].
Top Picks and Valuation Dynamics
At the center of Deutsche Bank’s selection are optical players Lumentum and Coherent, described as the highest-conviction ideas with buy ratings [1]. Both companies specialize in laser technologies essential for optical connections in AI systems, and both face supply constraints that allow for price increases [2]. Notably, Nvidia has invested $2 billion in each of these laser-chip designers to secure its supply chain for traditional optical transceivers and integrated co-packaged optics switching platforms [1]. Lumentum reported fiscal fourth-quarter revenue of $1.01 billion and expects fiscal Q1 2027 revenue between $1.225 billion and $1.275 billion [4]. This guidance implies a potential revenue growth of approximately 21.287 percent at the lower end of the forecast range [4].
Coherent generated $2.05 billion in fiscal fourth-quarter revenue, representing a 34% year-over-year increase, while non-GAAP gross margin expanded to 40.2% [4]. Deutsche Bank analysts note that both companies are essentially sold out and are raising prices due to production capacity constraints [3]. Beyond optics, Arista Networks received a buy rating with a target price of $220, distinguished by its liquid-cooling architectures designed to manage thermal loads [1]. Cisco Systems also earned a buy rating with a target price of $135, benefiting from the consolidation of its chips, optical components, and networking systems into a singular business unit [3].
Market Reaction and Future Outlook
Despite the positive analyst coverage, stock market reactions were mixed as bond yields rose, creating pressure on richly valued technology stocks [1]. Cisco closed down around 0.7%, Hewlett Packard Enterprise fell 2.6%, and Arista Networks dropped 3.3% following the reports [1]. Cisco had previously experienced a stock price decline in August 2026 following an earnings report that disappointed investors due to conservative forecasts [3]. The bank maintains a positive outlook on Arista Networks, citing an expected revenue growth of approximately 40% and strong free cash flow that may be undervalued [3].
Investors are advised to track revenue growth, gross margins, and capacity expansion closely as key indicators for these infrastructure plays [4]. Coherent has an upcoming catalyst with its PhotonLink launch scheduled for September 21, 2026, which could influence near-term performance [4]. Meanwhile, Lumentum’s fiscal Q1 results will serve as a test of whether its aggressive revenue guidance translates into sustained growth [4]. The broader economic impact relies on whether supply constraints persist as manufacturers attempt to add capacity to meet the surging demand for AI infrastructure [4].
