As AI infrastructure spending accelerates across the globe, two lesser-known companies are quietly capturing significant value from the ongoing buildout.
Taiwan Semiconductor Manufacturing (TSM) reported that June revenue jumped nearly 68% compared to the same period last year, signaling that AI demand is far from cooling off.
TSMC’s monthly growth figures tell a clear story: April showed 18% year-over-year growth, May came in at 30%, and June delivered that striking 68% surge.
For the first half of 2026, TSMC’s total revenue reached 2.4 trillion New Taiwan dollars, which translates to roughly $75 billion, up 36% from the same period in 2025.
TSMC is on track to generate over $40 billion from AI chip revenue alone in 2026, representing approximately 25% of its total revenue for the year.
Meta Platforms (META) added further weight to the bullish AI narrative by dramatically expanding its Hyperion data center project in Louisiana, now expected to reach at least $50 billion in direct investment.
Meta is also paying for 10 new natural gas plants to power the Louisiana site and is contributing over $1 billion toward local infrastructure including roads, water, and sewage systems.
Reports from Bloomberg have indicated that the total expected investment for the Hyperion project, including power infrastructure, could eventually exceed $250 billion, with full build-out not expected until around 2036.
Against this backdrop of surging AI infrastructure spending, Motley Fool contributors Matt Frankel and Rachel Warren highlighted two companies that most investors have overlooked.
Frankel pointed to Comfort Systems USA (FIX), one of the largest heating, ventilation, air conditioning, plumbing, and electrical contractors in the United States, focused on large commercial properties.
The company has pivoted sharply toward AI data centers in recent years, with revenue growing 56% year-over-year in its most recent quarter, earnings per share more than doubling, and its backlog growing by 80%.
Data centers increasingly require liquid cooling systems and highly precise electrical work, and Comfort Systems is among the few contractors capable of handling projects at that scale.
Frankel noted that TSMC’s updated capital expenditure guidance pointing to the high end of its previous range is a direct positive signal for companies like Comfort Systems that profit from the AI build-out.
Warren brought attention to Celestica (CLS), an electronics manufacturing services company that assembles advanced chips from companies like Nvidia and AMD into custom liquid-cooled AI server racks.
Celestica also builds the high-speed networking switches that allow tens of thousands of chips to communicate with each other inside massive hyperscaler data centers.
Warren noted that major tech companies like Meta are moving away from off-the-shelf hardware toward custom-designed proprietary AI server racks to maximize power efficiency and performance.
Because Celestica works closely with major chip designers including Broadcom, the company gets locked into multi-year data center build-outs early, giving it durable revenue visibility.
Both Comfort Systems USA and Celestica remain largely under the radar for many investors, despite sitting at the center of one of the most capital-intensive technology build-outs in history.
Frankel said Comfort Systems is “very high up on my watch list,” while Warren confirmed both companies are currently on her watch list as well.
If the AI hardware cycle continues on its current multi-year trajectory, these two picks-and-shovels plays look well positioned to capture a meaningful share of that growth.
