TT

Trane is a genuinely high-quality compounder, and the numbers leave little doubt. Revenue has grown every year from $14.1B in FY2021 to $21.3B in FY2025 (+7.5% YoY), while net income has roughly doubled over the same span to $2.92B (+13.7%). Crucially, profit is growing faster than the top line: operating income rose +13.4% and diluted EPS +15.5% to $12.98, evidence of operating leverage and mix improvement rather than just volume. Returns on capital are exceptional — 34.0% ROE on a $8.58B equity base that itself grew 15% — and the balance sheet is a fortress: long-term debt fell 9.2% to $3.92B against $1.76B cash, with liabilities/equity at a comfortable 1.49x. With $3.19B operating cash flow against just $383M capex, the company generates roughly $2.8B of free cash and is returning it aggressively ($1.48B buybacks, +15.7%; $837M dividends, +10.5%), shrinking the share count 1.3%.

The strategy reinforces the quality story. The 10-K shows management leaning into the structural decarbonization/energy-efficiency tailwind — the Gigaton Challenge and SBTi-validated targets — while bolting on capability: the January 2025 BrainBox AI acquisition (AI-driven HVAC optimization), European service/distributor deals, and a post-period 49% stake in building-automation player Kieback&Peter. These push the mix toward higher-margin connected controls and services and are easily funded given the deleveraging. The notable open item is the Aldrich/Murray asbestos Chapter 11: the subsidiaries are deconsolidated and a ~$270M 524(g) trust is proposed, but the plan still awaits court approval — a contained but unresolved legacy liability worth monitoring.
