Barlow’s Research Roundup: These companies powering and cooling new data centres see stock prices climb

The real signal here is not simply that data-center capex is still growing, but that the bottleneck is shifting from CPUs/GPUs to the physical plant around them. That matters because the industrial winners now have more durable pricing power than the semiconductor layer: liquid cooling, power conversion, and modular deployment are becoming the monetization points as rack density rises. The second-order effect is that vendors with installed base, certification, and service capability should compound share faster than pure-play hardware suppliers that only sell boxes.

This is also a rare setup where infrastructure names get both a volume tailwind and a spec-level mix tailwind. Higher-density builds pull demand toward higher-margin thermal and electrical content, while pre-fabrication compresses timelines and reduces customers’ tolerance for execution slippage—favoring incumbents with engineering depth and channel reach. The risk is that the market is already paying for “AI infrastructure” broadly, so the alpha will likely come from identifying who can convert revenue growth into margin expansion rather than from chasing the headline theme.

The macro overlay is more complicated: sustained oil strength is a tax on every energy-intensive buildout and a headwind for broader cyclicals, even if the direct inflation impulse is modest. If crude stays elevated for weeks, consensus earnings revisions could keep deteriorating outside energy, and that usually compresses multiples before EPS estimates fully roll over. The market may be underestimating how quickly higher fuel and freight costs can dent capex sentiment in the next two quarters, especially for businesses already facing stretched valuation multiples.
