AI supply-chain thesis — mapping bottlenecks, focus companies, and supply-chain exposure for investors.
**Bottleneck theme:** Cooling **Focus:** $NVT — nVent Electric plc nVent is the under-the-radar pure-play in liquid cooling, electrical enclosures, and rack thermal management — exactly the equipment categories that have moved from "commodity" to "AI-critical" in the past 24 months. The Q3 25 print of data-center orders +270% YoY signaled the inflection: hyperscalers and neoclouds are buying liquid-cooling infrastructure (CDUs, rear-door heat exchangers, manifolds) at multiples of historical rates, and nVent's ERIFLEX, HOFFMAN, and SCHROFF brands sit in many of the reference architectures. The Siemens / NVIDIA reference architecture inclusion was the credibility-check. The investment case is mid-cycle compounding plus a pure liquid-cooling kicker: ~25-30% of nVent revenue is now data-center, and that mix is the highest-margin and fastest-growing in the portfolio. Risks: Vertiv ($VRT), Eaton-Boyd ($ETN), Modine ($MOD), Schneider, and a long tail of Asian competitors all want the same hyperscaler liquid-cooling sockets. Stock has rerated significantly; further upside requires sustained order growth and disciplined integration of recent bolt-on acquisitions. Pair with $VRT, $ETN, $MOD for diversified data-center cooling exposure.
