Trane Technologies plc

Its installed base spans commercial buildings, residential homes, and refrigerated transport fleets in approximately 100 countries.

This is a story about a well-run industrial compounder finding itself at the center of the most consequential capital-spending cycle in a generation. Data center construction has transformed demand for large-scale cooling equipment, turning what was historically a GDP-plus growth business into one posting 24% organic bookings growth and a record $10.7 billion backlog. But the excitement around data centers obscures a quieter story that may matter more: the steady transformation of the business model from equipment sales toward a higher-margin, recurring-revenue services franchise that now accounts for over a third of enterprise revenue and has compounded at a low-teens rate since 2020. The file turns on a single question: whether the market is overpaying for a cyclical industrial at a peak multiple, or whether the secular forces reshaping the business justify re-rating it as something more durable.
