HVAC Leader Soars 8% on Earnings Surprise, Market Cap Increases by 11 Trillion in a Day

Trane Technologies PLC (NYSE: TT) shares closed at $426.07 on the New York Stock Exchange on the 29th, up 8.09%, boosting its market capitalization by about $8.3 billion (roughly ₩11 trillion). Trading volume reached 2.62 million shares—well above its average—as the company’s fourth-quarter 2025 results modestly topped market expectations and its 2026 revenue and earnings-per-share guidance came in strong. In Q4, Trane reported approximately $5.1 billion in revenue and adjusted EPS of $2.86, confirming year-over-year growth and healthy bookings and backlog.

In its announcement, Trane said full-year 2025 organic revenue grew in the high single digits, and backlog climbed to a record high of about $7.8 billion. For 2026, the company expects revenue to increase roughly 8.5%–9.5% year over year and adjusted EPS to range from $14.65 to $14.85, reinforcing its medium-term growth outlook.
