Cash is king in AI right now, and the latest earnings reaction to Microsoft and Alphabet shows it. Wall Street is rewarding companies that can fund massive AI computing needs from their own cash flow rather than constant capital raises. That surge in demand for AI infrastructure creates a potential opening in the physical plumbing of AI. This article walks through three hardware focused stocks powering that build out.

The stocks covered below are just a first pass at the companies wiring up AI data centers, and the full screen surfaced 22 more hardware focused businesses with equally detailed narratives that are not included in this article.

To size up that broader field and identify which AI infrastructure plays best fit your risk and time horizon, head straight into the AI - Networking and Servers screener.

Cisco Systems (CSCO)

Overview: Cisco Systems builds networking gear and software, with data center switches and optical interconnects forming its clearest link to AI infrastructure.

Operations: Cisco generates about US$63.3b from Computer Networks, with roughly US$34.4b from the United States and US$16.6b from EMEA regions.

Market Cap: US$439.1b

Cisco Systems matters for this AI hardware screen because its switches, optics, and control software sit directly in the traffic path of large training clusters.

"Cisco is using its workforce as a test bed to dogfood products like AgenticOps, Cisco AI Defense, and Cisco Cloud Control. Success will serve as a live blueprint to sell enterprise AI architectures, Webex, and AI-enabled hardware/software to external enterprise clients"

What happens to Cisco’s earnings profile if a single assumption about how customers value that bundled AI networking stack proves too conservative?

If that bundled AI networking thesis is what really moves the needle for Cisco Systems, read the full narrative for Cisco Systems to see how that scenario could accelerate.

Lumentum Holdings (LITE)

Overview: Lumentum Holdings supplies high speed optical modules and photonic components that move data inside cloud and AI data centers worldwide.

Operations: Lumentum reports US$3.0b from Integrated Enterprise, with revenue drawn from the United States, Thailand, Mexico, Hong Kong, China, Japan and EMEA.

Market Cap: US$78.5b

Lumentum matters in this AI networking and servers screen because its lasers and optical modules form key links between accelerators, switches and racks as hyperscalers rewire their data centers for heavier GPU traffic.

"The core submarket that matters most for long-term value is high-speed optical components for cloud and AI data centers, where bandwidth demand from GPU clusters is driving a rapid upgrade cycle to 800G and 1.6T optics."

What happens to Lumentum’s margin profile if a single assumption about how tight that high speed optics supply stays proves too optimistic?

If that supply demand tension is what you keep circling back to, read the full narrative for Lumentum Holdings to see how pricing power and AI exposure could really scale.

Littelfuse (LFUS)

Overview: Littelfuse supplies protection, control and power components, with its Electronics segment safeguarding data center switches, optical modules and server power rails.

Operations: Littelfuse generates about US$1.47b from Electronics, US$687.9 million from Transportation and US$454.6 million from Industrial, with revenue spread across the United States, China and other countries.

Market Cap: US$9.7b

Littelfuse matters for this AI networking and servers screen because its protection devices help keep hyperscale data center hardware running reliably under heavy electrical stress.

"Expanding adoption of high voltage architectures in data centers, grid and transportation applications is expected to increase Littelfuse content per system, with management targeting a 25 to 30% data center revenue CAGR over five years and citing 2 to 4 times higher content in future high voltage systems, which can support revenue growth and earnings."

What happens to Littelfuse’s earnings power if a single assumption about execution on its high voltage growth plan does not hold?

If that execution risk around Littelfuse keeps nagging at you, jump into the full narrative for Littelfuse to see how high voltage ambitions could be accelerating or stalling.
