Runaway “Trumpflation,” a possible Fed jolt on Sept. 16, and an AI infrastructure boom powered by debt have left markets feeling stretched, yet full of promise. Investors who care about balance sheet strength and lower leverage now face a rare fork in the road. This piece unpacks that setup and highlights 3 U.S. AI infrastructure enabler stocks exposed to these forces, and explains why they may deserve a closer look today.
The three stocks that follow are only a sample set, and the full screen surfaced 12 more U.S. AI infrastructure enablers with similarly strong balance sheet stories and differentiated business cases that are not covered here. To see the complete picture and identify which ideas best fit your own risk and return preferences, head straight to the U.S. High-Quality, Low-Leverage AI Infrastructure Enablers screener.
Powell Industries (POWL)
Powell Industries designs and builds custom power control rooms, switchgear, and electrical systems that keep large industrial sites and AI hungry data centers supplied with reliable electricity. The business generates about US$1.16b in revenue from electric equipment and is valued at roughly US$6.65b in market cap.
Powell Industries plugs into the AI infrastructure theme through medium voltage equipment and control systems that support data center and utility power projects, while carrying a balance sheet profile that screens as low leverage and relatively high quality. A record backlog of about US$2.4b, including large data center and utility orders, gives this electrical specialist unusual revenue visibility if AI capex slows. However, the outcome depends on how one unseen pressure affects pricing power and earnings resilience.
To see whether that pressure is already visible in contracts and margins, pull up the analysis report for Powell Industries and test how Powell Industries holds up if AI capex cools.
Calix (CALX)
Calix fits into the screener’s AI infrastructure angle by giving broadband providers cloud tools and hardware to run richer connected experiences. This makes its business model directly tied to how service providers adapt their networks for heavier AI era traffic.
Calix develops and sells communications access systems and software that generated about US$1.11b in revenue, almost entirely from this segment, and has a market value near US$2.22b. That focus on broadband platforms and services is central to its AI oriented connectivity role.
"The upcoming rollout of Calix's third-generation platform, which integrates agentic AI capabilities, is expected to dramatically accelerate broadband providers' ability to monetize new services and experiences across residential, business, and municipal segments; this can drive higher ARPU, increased subscriber growth, reduced churn, and ultimately stronger revenue expansion beginning in the second half of 2025 and accelerating into 2026."
The key issue for Calix is how one unresolved funding and leverage question shapes the durability of those AI era ambitions.
That funding overhang is exactly why reading the full narrative for Calix can help you see how Calix’s AI ambitions could accelerate or stall from here.
Kulicke and Soffa Industries (KLIC)
Kulicke and Soffa Industries supplies the chip assembly equipment that lets AI processors and memory actually get packaged for data centers, with most of its roughly US$950 million revenue coming from Ball Bonding Equipment at about US$588 million, and a market value near US$4.5 billion.
Kulicke and Soffa Industries links directly into the screener’s AI infrastructure theme through the packaging tools that sit downstream of chip fabrication. The real intrigue is how its higher value Advanced Solutions portfolio could reshape the earnings profile if AI hardware keeps demanding denser, more complex assembly.
"Accelerating adoption of advanced packaging, including fluxless thermocompression for heterogeneous logic and HBM, is expected to drive a mix shift toward higher value systems and support structurally higher revenue and gross margins as fiscal 2026 ramps."
The catch is how one shift in customer spending patterns could either reinforce that richer product mix or quickly squeeze the margin story investors are watching.
That customer shift is exactly what the full narrative for Kulicke and Soffa Industries unpacks. It reveals how Kulicke and Soffa Industries could turn packaging mix, capex cycles, and margin pressure into an underappreciated AI gear change.
