With energy costs, inflation debates, and bond markets all in focus, many investors are looking beyond headline-grabbing AI software stocks and toward the physical backbone that keeps AI running. This is where AI Infrastructure Stocks come in, targeting companies that build and operate the power, cooling, and connectivity that large-scale AI systems rely on. As central banks weigh interest rate decisions and geopolitical tensions affect energy markets, this screener aims to highlight businesses that turn AI-related demand into cash flow. Ahead, you will see 3 of the strongest stocks filtered from this AI Infrastructure Stocks universe.

TTM Technologies (TTMI)

Overview: TTM Technologies is a US based manufacturer of high end printed circuit boards, RF components, and mission systems that sit inside data centers, defense platforms, and industrial and automotive electronics, connecting chips to the real world. The company supports customers across aerospace and defense, AI and cloud infrastructure, networking, medical, and industrial markets with design, quick turnaround manufacturing, and complex assembly services.

Operations: TTM Technologies generates about US$1.7b from Commercial operations and US$1.3b from Aerospace & Defense, with the United States contributing roughly US$1.6b of revenue and other international markets about US$1.2b.

Market Cap: US$15.2b

Investors looking at AI infrastructure may pay attention to TTM Technologies because it sits at the intersection of large scale data center buildouts and defense electronics demand, supplying advanced PCBs and RF systems that AI servers and military platforms use. Reported earnings growth has been strong, margins are improving, and recent capacity expansions in locations such as Syracuse and Penang, plus planned European acquisitions, are focused on higher value products. At the same time, a high P/E, concentrated customer base, heavy capital spending, funding that relies on external borrowing, and geopolitical exposure in China present risks, which is a key consideration for AI infrastructure focused portfolios.

Margins at TTM Technologies are improving and capacity is expanding, but the real story is how that feeds into cash flows and valuation, especially with customer concentration and China exposure in the mix, so it is worth going through the 4 key rewards and 2 important warning signs

Forgent Power Solutions (FPS)

Overview: Forgent Power Solutions designs and builds the electrical distribution equipment that keeps data centers, the power grid, and heavy industrial sites running, from switchgear and transformers to power distribution units and UPS eHouses. The company also supports these systems with maintenance, testing, and retrofit services for technology, utility, and industrial customers.

Operations: Forgent Power Solutions generates about US$1.2b in revenue from the design, development, manufacture and marketing of its products and services, all from North America.

Market Cap: US$13.9b

Forgent Power Solutions sits in the heart of AI infrastructure, supplying the power gear that data centers and utilities rely on, and recent numbers have drawn attention, with earnings growth of 88.1% over the past year and guidance pointing to revenue of US$1,350m to US$1,390m. Some analysts highlight potential for further upside, yet the stock still carries a P/S multiple above the broader US electrical industry, and net profit margins of 1.4% keep execution under the microscope. Heavy use of external borrowing, limited interest coverage, and a very new board with short tenures and relatively low independence add to the risk side of the ledger. For investors who want to weigh rapid growth, a large backlog, and frequent equity deals against funding and governance considerations, Forgent Power Solutions may be a company worth a closer look in the AI infrastructure space.

Forgent Power Solutions has earnings racing ahead while thin margins and heavy borrowing keep the pressure on, so it is worth reading the full 4 key rewards and 1 important major warning sign to see what could shift this balance next.

Vertiv Holdings Co (VRT)

Overview: Vertiv Holdings Co builds the power, cooling, and critical infrastructure that allow AI data centers, telecom networks, and industrial facilities around the world to run reliably, including liquid cooling systems, uninterruptible power supplies, racks, and monitoring software sold under brands such as Vertiv, Liebert, and Avocent.

Operations: Vertiv generates about US$7.0b in revenue from the Americas, US$2.4b from Asia Pacific, and US$2.3b from Europe, the Middle East & Africa, with roughly US$1.0b eliminated as intersegment sales.

Market Cap: US$122.5b

Vertiv has become a focal point in AI infrastructure because its liquid cooling and power systems sit at the heart of high density GPU data centers, supported by a US$15b backlog and demand for AI ready facilities. Revenue and earnings growth are strong, profitability has improved with net margins at 14.4%, and recent acquisitions in thermal management and services, plus new plants in regions such as Malaysia, expand its reach. At the same time, a high P/E, reliance on a handful of hyperscale customers, and funding that leans entirely on external borrowing mean the stock carries meaningful risk. For investors weighing rapid growth, expanding services, and valuation considerations, Vertiv is a company that may warrant closer examination within the AI infrastructure theme.

Vertiv’s rapidly expanding AI data center footprint, rising margins, and reliance on a few hyperscale customers raise big questions about how much growth is already priced in. Get the full context in the analyst forecasts for Vertiv Holdings Co
