Is TT Stock Worth Buying as Growth Runs Into a Premium Valuation?

Trane Technologies plc TT enters the second half of 2026 with strong demand signals. Record bookings, a much larger backlog and rising earnings expectations give the company substantial revenue visibility.

The counterweight is valuation. TT already trades above several benchmarks, while inflation, reinvestment and EMEA weakness are pressuring margins. That makes the investment case less about growth durability and more about the price investors are paying for it.

TT’s Backlog Supports a Strong Growth Case

Second-quarter organic bookings increased 37%, while backlog reached a record $12.1 billion, up roughly 70% year over year. The enterprise book-to-bill ratio reached 123%, and every operating segment finished above 100%, meaning orders exceeded revenues across the portfolio.

Demand was especially strong in Americas Commercial HVAC, where bookings rose 50% and applied equipment orders increased 130%. The business ended the quarter with backlog up about 90%, while demand remained broad-based across data centers, schools, offices, warehouses and high-tech industrial projects.

Trane’s Earnings Outlook Keeps Rising

Adjusted earnings increased 11.1% year over year to $4.31 per share in the second quarter. Revenues rose 10.6% to $6.35 billion, with both results exceeding the Zacks Consensus Estimate.

The Zacks Consensus Estimate for 2026 revenues is $23.57 billion, implying growth of about 10.5%. The EPS estimate for the current fiscal year has increased 2.8% over the past four weeks. Management also raised full-year adjusted continuing earnings guidance to $15.20-$15.30 per share.

TT’s Premium Multiple Raises the Bar

TT trades at 27.24X forward 12-month earnings. That compares with 21.22X for the Zacks sub-industry; it also trades above its five-year median multiple of 26.83X. Investors are therefore paying a premium not only to broader benchmarks but also to TT’s own longer-term valuation history, leaving less room for execution setbacks.

Trane Faces Margin Pressure and EMEA Risk

Second-quarter adjusted operating margin declined 60 basis points (bps) year over year to 19.7% despite 9% organic revenue growth. Inflation and elevated business reinvestment outweighed the benefit of volume growth and positive pricing, and management expects price versus total inflation to remain unfavorable in the second half.

EMEA adds another layer of risk. Organic revenues fell 4% and adjusted operating margin declined 420 basis points to 13.1%. Management expects the Middle East conflict to reduce second-half revenue by about $100 million and operating income by about $30 million. Carrier Global Corporation CARR is another global provider of intelligent climate and energy solutions, making it a relevant HVAC comparison. Johnson Controls International plc JCI sells commercial HVAC equipment, controls and building-management systems, adding another competitive reference point for Trane’s commercial building business.

TT’s Growth and Momentum Scores Support Patience

TT’s growth case remains strong, but the premium multiple and margin pressures make patience reasonable at current levels. The company has substantial backlog visibility and improving estimates, yet the valuation already prices in a meaningful degree of optimism.

The stock currently carries a Zacks Rank #3 (Hold). You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.

It also has a Growth Score of B, Momentum Score of A, Value Score of D and VGM Score of B. The growth and momentum grades are favorable, while the weaker Value Score captures the valuation trade-off. The Zacks Rank points to a more measured stance rather than a fresh buy signal.
