AI cooling demand boosts key contractors and suppliers with strong earnings and big backlogs.

The surge in AI workloads is driving a major increase in demand for data center cooling and power infrastructure. Companies like Comfort Systems USA, Eaton, Vertiv Holdings, nVent Electric, and Modine Manufacturing are seeing strong earnings beats, growing backlogs, and raised guidance due to this trend. Comfort Systems, for example, reported a 54% EPS beat and doubled its backlog to $12.45 billion. Modine secured a $4 billion long-term contract with a major hyperscale customer. These firms are positioned to benefit significantly from the ongoing AI-driven data center expansion, making them key players to watch in the sector.
