Comfort Systems USA, a contractor installing HVAC and electrical systems inside AI data centers, trades at nearly twice Nvidia's forward earnings multiple, even though Nvidia's chips and CUDA ecosystem made the entire buildout possible. x.com 

Modine Manufacturing is a pure play on data-center thermal management, and its November 18 investor day could send it higher if it confidently sets big 2028-29 targets. It already cites two hyperscalers and one neocloud as customers, and which hyperscalers they are does not matter. Its valuation, which had grown stretched along with Vertiv's, now looks more intriguing than ever. x.com 

Vertiv should beat and keep raising 2026 guidance because AI data center demand still exceeds supply. The proprietary pipeline added 50+ GW in 1Q26, 415 GW in the US since January 2023. Even flat orders near $18 billion would lift backlog from $15 billion to about $18 billion, implying about $25 billion of 2027 sales versus the Street's $16.9 billion. Base EPS of $6.75/$9.50 for 2026/27 tops the Street at a PEG under 1x. Margins are the watch item; the big run makes the print less attractive. … Show more

Vertiv is a great company, supplying the power and cooling AI data centers need as rack densities climb past 100kW, with its cooling systems a major draw. Its liquid-cooling, power, heat-rejection and prefabricated modular systems bring more of the data-center stack under one roof, which could become a meaningful competitive advantage. Grid power and thermal capacity, not silicon supply, are now the limiting factor in AI. x.com  x.com
