TT · Q4 2025 Earnings

Trane Technologies

Reported January 29, 2026

30-second summary

Q4 FY2025 revenue grew 6% YoY to $5.15B with adjusted EPS of $2.86 beating the high end of the prior $2.75–$2.85 guide by a penny, and applied bookings ran +120% with a record 200% book-to-bill — the second consecutive quarter of applied bookings growth above 100%. FY2026 guidance lands at 6–7% organic revenue growth and $14.65–$14.85 EPS (+12–14%), but one detail tempers the print: Q1 FY2026 organic growth is guided to "flattish" with EPS of just ~$2.50. FY2026 organic leverage is guided to 25%+ (the long-term framework), after FY2025 ran at the elevated 30%+ target. Backlog of $7.8B (up from $7.2B in Q3) and a 112% enterprise book-to-bill keep the structural thesis intact; the bull case now hinges on the H2 FY2026 inflection management is explicitly underwriting.

Management tone

Q1 anchor: Not covered → Q2: "Applied is structurally advantaged, residential is transitory" → Q3: "Residential reset extends into 2026 H2, but leverage is structural at 30%+ for FY2025" → Q4: "Backlog and applied bookings dominate the narrative; FY2026 leverage returns to the 25%+ long-term framework"

The applied systems story has escalated for a third consecutive quarter, from a "growth category" framing in Q2 to ">60% applied orders" in Q3 to a record 200% book-to-bill in Q4 FY2025. From the prepared remarks: "Applied solutions bookings were up more than 120%, with a record book-to-bill of 200%, marking the second consecutive quarter with applied bookings growth exceeding 100%." What was a thesis-defining data point in Q3 is now a multi-quarter pattern, which is the more durable signal. The 9-month applied equipment ship cycle means most of this is FY2026 revenue.

Data center framing crossed a line this quarter from "validated vertical" to "co-design partner." Q3 mentioned NVIDIA collaboration without specifics; Q4 FY2025 added the Stellar Energy acquisition and a defensive statement from management: "I have not seen a reference design or data center of the future that does not include chillers, just to be very clear." That defensiveness — surfaced in response to bear theses about liquid cooling displacement — reads as management actively rebutting demand-destruction narratives. The Stellar Energy deal moves Trane from component supplier into turnkey data center cooling.

The residential narrative tightened. Q2 had residential flat; Q3 cut to -20% Q4 with H2 2026 recovery; Q4 FY2025 confirms residential is now framed as "flat to down 5% for 2026" with inventory "in the position we want it to be." From the remarks: "We were very, very intentional in the fourth quarter to get the inventory right... we expect 2026 to get progressively better, with tailwinds building later in the year as comps ease." Inventory normalization being deliberate and complete is materially more credible than the Q3 framing of an ongoing reset.

On organic leverage, Q3 raised the FY2025 target to 30%+ with CFO Kuehn explicitly tying it to durable scenario planning and "ring-fenced" investments. The FY2026 guide of 25%+ is a return to the long-term framework number Trane has historically anchored to. Whether FY2025 actual leverage landed at or below the 30%+ target was not isolated in the release, so the FY2025-to-FY2026 step is not directly comparable; the most charitable read is that the elevated FY2025 target reflected specific mix effects, while the less charitable read is that incremental margin pressure from tariffs and residential mix will absorb leverage in FY2026.

Recurring themes management leaned on this quarter:

Applied systems dominance with consecutive 100%+ booking quartersData center co-design partnerships driving reference designs and innovation pipelineCommercial HVAC broad-based growth across 12 of 14 tracked verticalsInventory normalization in residential completed; recovery expected H2 2026Backlog visibility translating orders to revenue with predictable cyclesMargin expansion through operating leverage and operational excellence

Risks management surfaced:

Residential market remains challenged with flat to down 5% outlook for 2026Transport refrigeration market expected to be flat to down low single digits before recovery late 2026China market showing double-digit declines in bookings and revenueTariff and commodity cost inflation requiring ongoing price mitigation and hedgingData center thermal management system service intensity may decline if chillers run less frequently, impacting service tail economics

Answers to last quarter's watch list

Q4 FY2025 organic growth landing at or above the ~3% guide, ex-residential at ~7% — Resolved positively on the headline (4% actual vs. ~3% guide, +1pp beat) and applied bookings +120% reinforce ex-residential strength. CFO Kuehn confirmed Q4 FY2025 organic was "7% excluding residential," matching the prior guide exactly.

Resolved positively

FY2026 initial guidance framing — residential trough magnitude and commercial HVAC growth rate — Residential guided to "flat to down 5%" for FY2026 (modest improvement from Q4 FY2025's -20% run rate). Americas commercial HVAC was framed as up ~10% with applied bookings momentum implying commercial HVAC remains the dominant growth engine. FY2026 leverage returns to the 25%+ long-term framework, after FY2025 ran at the elevated 30%+ target.

Continue monitoring

Applied bookings growth normalization — Applied bookings +120% with a record 200% book-to-bill, marking the second consecutive quarter of applied bookings growth above 100%. The three-year stack is now extended further; no deceleration signal.

Resolved positively

Backlog mix disclosure for 2026+ — Enterprise backlog $7.8B (up from $7.2B at Q3), with Americas commercial HVAC backlog +25% and EMEA +40% vs. YE 2024. CFO Kuehn disclosed "a bit over a billion dollars of backlog that's for 2027 and beyond, up more than 30% versus a year ago" — a partial restoration of the forward-booked dollar disclosure cadence.

Resolved positively

Gross margin trajectory — Q4 FY2025 gross margin 34.1% compressed 280bps QoQ from Q3's 36.9%. Residential deleverage (with production days cut by one-third, driving ~60% deleverage in that business) is the management-cited driver. FY2025 gross margin of 36.1% held.

Resolved negatively

Tariff cost re-disclosure — Management acknowledged tariff headwinds for FY2026 but did not refresh a specific dollar impact figure equivalent to Q2's $140M baseline.

Continue monitoring

What to watch into next quarter

Q1 FY2026 EPS landing at or above ~$2.50 and organic growth above zero — "flattish" leaves no room for downside, and a print below $2.50 would force a re-rate of the H2 FY2026 inflection thesis.

FY2025 actual organic leverage disclosure — whether management isolates where FY2025 leverage landed against the 30%+ target, which would clarify whether the FY2026 25%+ guide reflects conservatism or actual mix headwinds.

Asia Pacific China trajectory — Q4 FY2025's -5% segment print and "double-digit declines in China bookings and revenue" reversed the Q3 stabilization thesis. Watch whether Q1 FY2026 sequentials improve or whether China is now an extended drag.

Data center demand sustainability post-Stellar Energy — whether applied bookings hold above 100% growth for a third consecutive quarter and whether Stellar Energy integration shows up in segment disclosure.

Gross margin recovery into Q1 FY2026 — whether the 280bps QoQ Q4 FY2025 compression reverses or persists. A second quarter at ~34% would shift the diagnosis from residential-deleverage-driven to structural.

Residential print vs. the "flat to down 5%" FY2026 framing — Q1 FY2026 residential is the cleanest test of whether the inventory-normalization-complete narrative holds. Down >5% in Q1 FY2026 ex-comp effects would push recovery into late FY2026.

FY2026 FCF conversion — whether the 100%+ guide holds after FY2025 missed at 98%. Two consecutive years below 100% would warrant a structural flag.
