## Key stats

- **Ticker:** TT
- **Market Cap:** ~$110B

## Moat

Global HVAC and climate-solutions leader with a dominant Americas Commercial position, a high-margin recurring service base, and an accelerating presence in modular data-centre cooling — moat sources are channel embedment, refrigerant compliance scale, and service-fleet density.

### The Refrigerant Transition and Service-Fleet Moat

Trane's moat is **specification embedment plus a service-and-controls flywheel that compounds with each refrigerant transition** — and the AI data-centre cooling cycle now layers a TAM expansion on top:

- **Refrigerant Transition Compliance Scale:** Each EPA/global refrigerant phase-down (R-410A → A2L blends, and the next step beyond) forces a re-engineering of the entire chiller, rooftop, and VRF lineup. Trane has the scale to certify across geographies fastest, capture the share-shift window, and price-in the regulatory premium — small competitors lose share each cycle.
- **Modular Data-Centre Cooling via Stellar Energy:** The Stellar Energy acquisition (closed early 2026) makes Trane a top-tier provider of modular chiller plants and packaged cooling skids for hyperscaler campuses. Stellar is guided to ~$500M revenue in 2026 scaling to $1B+ in 2-3 years at mid-teens-plus EBITDA, with reference designs for liquid-to-air chilled-water rejection.
- **Service Channel and Building Controls Density:** Trane's service technician fleet, BAS (building automation system) installed base, and Tracer SC controls platform create high-margin recurring revenue and a switching cost — once a campus is on Trane controls and service, the next chiller replacement defaults to Trane equipment.

**Moat verdict:** Trane is a high-quality cyclical compounder with real moats in refrigerant compliance scale and service-fleet embedment, now layered with a data-centre cooling growth lane via Stellar. Valuation has re-rated to a premium that prices much of the data-centre story in; the franchise is durable but the entry multiple matters.

## Growth

Q1 2026 organic bookings +24%, backlog $10.7B (+30% vs YE25), FY26 EPS guide raised to $14.75-$14.95 (+13% YoY mid). Americas Commercial HVAC + data-centre cooling drive the growth; Residential and EMEA are slower-growing ballast. Stellar Energy adds a $1B data-centre cooling growth lane on top of the core franchise.

- **Revenue CAGR estimate:** 10-13%
- **Primary type:** TAM expansion
- **Margin trend:** expanding
- **Key risk (moderate):** If hyperscaler 2027 capex moderates and data-centre cooling bookings flatten, the recently expanded multiple compresses fast — Trane is structurally cyclical (residential + EMEA) and the data-centre cooling growth is now priced in.
- **Drivers:**
  - Americas Commercial HVAC — Data-centre + reshoring drive 20%+ bookings growth; backlog at record (accelerating)
  - Stellar / Data-Centre Cooling — $500M FY26 → $1B+ in 2-3 years at mid-teens+ EBITDA margin (accelerating)
  - Residential & EMEA — Mid-single-digit growth on refrigerant transition tailwind, more cyclical (stable)
- **Score derivation:** Base 70 (8-15% CAGR mid-band) + 5 backlog visibility (+30% YoY, record) + 4 data-centre cooling TAM expansion via Stellar - 5 cyclicality risk (residential + EMEA exposure) = 74

## Valuation

At ~$493 TT trades at ~33× FY26 EPS midpoint — premium to industrial peers and a meaningful re-rating versus the historical 25-28× range. Backlog and Stellar story support the multiple but the asymmetry now leans modestly downside.

| Multiple | Value | Note |
| --- | --- | --- |
| Forward P/E (FY26) | ~33× | EPS $14.85 mid; data-centre re-rating |
| Forward P/E (FY27) | ~29× | Assumes ~13% EPS growth on backlog conversion |
| PEG Ratio | ~2.7× | Premium on durable low-double-digit growth |
| Price / Sales (FY26) | ~4.7× | Reflects services + data-centre mix premium |
| EV / EBITDA (NTM) | ~22× | Premium to Carrier ~18× and Lennox ~20× |

Premium but supported by record backlog and the Stellar data-centre lane; not cheap, with downside re-rating risk on capex moderation. _(as of May 2026)_

## Price scenarios

### Bear — $360

Data-centre cooling bookings normalise in 2027, residential cycle stays soft, multiple compresses to ~22-24× on growth normalisation.

- Hyperscaler 2027 capex grows <10% YoY, slowing data-centre cooling orders
- Residential refrigerant transition pull-forward unwinds in 2027
- Stellar integration runs slower than guided, dampening data-centre revenue mix

### Base — $545

FY26 EPS lands near $14.85, FY27 grows to $16.75 on backlog conversion plus Stellar ramp, multiple sustains 31-33×.

- Backlog continues building through 2026 with bookings >1.1× book-to-bill
- Adj operating margin expands ~50 bps on services + data-centre mix
- Stellar revenue tracks $700-800M in 2027 at mid-teens-plus EBITDA

### Bull — $720

Data-centre cooling super-cycle extends through 2028, Stellar exceeds $1B run-rate by 2027, FY28 EPS exceeds $20, multiple expands to ~36×.

- AI data-centre cooling capex sustains 25%+ growth through 2028
- Trane wins reference-design slots in next-gen liquid-to-chilled-water rejection systems
- Refrigerant phase-down in EMEA accelerates the international upgrade cycle
