TRANE TECHNOLOGIES PLC (TT) valuation

0 · TTM reconstruction (anchor: Q12026, 2026-03-31)

The latest filing is a 10-Q, so "base year" revenue / EBIT / OCF / CapEx are reconstructed as trailing-twelve-month values. Per-quarter facts (typical for income-statement items) get summed across four quarters; YTD-cumulative facts (typical for cash-flow items) use prior FY + YTD_now − YTD_{prior year same quarter}.

1 · Enterprise-value target (what the DCF must match)

Diluted shares = point-in-time basic × 1.0068× (filer's TSM dilution multiplier from WeightedAverageNumberOfDilutedSharesOutstanding ÷ WeightedAverageNumberOfSharesOutstandingBasic , period ending 2026-03-31 ). See the diluted-shares methodology.

Noncontrolling interest = book NCI on the consolidated BS ( MinorityInterest $21.6M ). Subtracted from the equity bridge so per-share fair value reflects the common-shareholder claim only. See the NCI methodology.

Market cap     = price × diluted shares
               = $416.74 × 222.6M
               = $92.75B

EV target      = market cap + total debt + NCI − cash & equivalents
               = $92.75B + $3.92B + $21.6M − $0
               = $96.69B
            

2 · Starting NOPAT (base year 0)

Tax rate source: 3-year median of EffectiveTaxRate. See the tax-rate methodology for the precedence ladder.

Tax rate fades from 19.4% at year 0 to 21.0% at year 10 (US federal statutory floor). The current effective rate is the most honest reading of this filer's recent economics, but holding it as the perpetuity rate would compound a one-off NOL benefit / R&D credit / foreign-mix tilt across the whole horizon. WACC's after-tax cost of debt uses the terminal rate so the discount rate is consistent with the long-run cash flows it discounts.

GAAP EBIT          = $3.92B   (18.2% of revenue)
× (1 − tax rate)  = × (1 − 19.4%) = × 0.8064
= NOPAT₀            = $3.16B
            

3 · Invested capital & starting ROIC

Invested capital = total debt + book equity − cash
                 = $3.92B + $8.59B − $0
                 = $12.51B

Raw ROIC₀        = NOPAT₀ / Invested capital
                 = $3.16B / $12.51B
                 = 25.3%
(no cap applied; raw value is within the 40.0% ceiling)
            

4 · WACC derivation

Cost of equity from CAPM , after-tax cost of debt from a synthetic credit rating built off interest coverage , weighted by market values of equity and debt. Inputs: Rf is FRED DGS10's 90-day mean (latest 2026-05-29); β is the 5-yr weekly regression vs VOO, floored at 1.00 for the cost-of-equity step (the empirical security market line is much flatter than CAPM predicts — Frazzini-Pedersen 2014, "Betting Against Beta" — so unfloored CAPM systematically under-estimates required return for low-β filers); ERP is the latest Damodaran US total ERP (2026-01-01). The synthetic rating is a Damodaran coverage-table heuristic, not an empirical S&P / Moody's letter. It maps EBIT-÷-interest into a letter-grade bucket and reads the spread out of a lookup table; an actual agency rating considers qualitative factors (governance, market position, jurisdiction, off-balance-sheet exposure) the coverage ratio can't capture. For most filers the gap is small; for capital-light, high-coverage names — software, IT services, consumer brands — this method tends to print AAA/AA where actual agency ratings sit at A/BBB+, and the resulting cost of debt is a few tens of bps light. WACC is more sensitive to β and weights than to credit, so the headline barely moves; flagged here so readers don't read the rating as an empirical agency assessment.

Cost of equity        = Rf + β × ERP
                      = 4.3% + 1.12 × 4.5%
                      = 9.4%

Cost of debt (pretax) = Rf + credit spread
                      = 4.3% + 0.6%   (synthetic AAA, EBIT ÷ interest = 17.5×)
                      = 4.9%
× (1 − tax rate)      = × (1 − 19.4%)
= Cost of debt (a/t)  = 3.9%

Weights               E/V = 95.9%, D/V = 4.1%

WACC (raw)            = E/V × cost_e + D/V × cost_d_after_tax
                      = 95.9% × 9.4% + 4.1% × 3.9%
                      = 9.1%
                

5 · Growth path construction

Source       = analyst consensus (absolute forecast, TTM-anchored): Y1 = 8.2%, Y2 = 8.4%

Detailed derivation:
  Current-FY analyst avg revenue forecast = $23.38B   (FY-over-FY vs FY2025 actual = 9.6%)
  Next-FY analyst avg revenue forecast    = $25.35B   (FY-over-FY vs current-FY forecast = 8.4%)
  Base revenue (TTM) = $21.60B
  Latest completed FY revenue (FY2025) = $21.32B   (denominator for the FY-over-FY check above)

  Y1 = current-FY forecast / TTM base revenue − 1
     = $23.38B / $21.60B − 1
     = 8.2%

  Y2 = next-FY forecast / current-FY forecast − 1
     = $25.35B / $23.38B − 1
     = 8.4%

  Note: the absolute analyst forecast is re-anchored
  against TTM (rather than the FY-over-FY consensus
  rate above) because the TTM base spans the current
  FY only partway. Re-anchoring keeps the growth rate
  consistent with the projection's starting revenue
  level.
Clamp        = [2.5%, 60%] (no sub-terminal or 60%+ starts)
Plateau rate = 8.4% (Y2 — held from year 2 through end of plateau)
Tier         = 3 years (rule: plateau rate < 15% → 3y, < 25% → 5y, else 7y)
Plateau      = 3 years
Fade         = linear from effective Y2 to terminal 2.5% across the remaining 7 years

Effective Y1 growth after solver bumps = 16.2%
Effective Y2 growth after solver bumps = 16.4%
Growth by year:
  Y1 = 16.2%
  Y2 = 16.4%
  Y3 = 16.4%
  Y4 = 14.5%
  Y5 = 12.5%
  Y6 = 10.5%
  Y7 = 8.5%
  Y8 = 6.5%
  Y9 = 4.5%
  Y10 = 2.5%
                

6 · Margin path construction

Starting margin (Y0) = 18.2%   (source: TTM EBIT margin (GAAP) — within 4pp of 3-yr mean)
Target margin (Y10)  = 21.8%   (solver output, normal band)
Year-t margin        = starting + (target − starting) × (t / 10)
Margin by year:
  Y1 = 18.5%
  Y2 = 18.9%
  Y3 = 19.3%
  Y4 = 19.6%
  Y5 = 20.0%
  Y6 = 20.3%
  Y7 = 20.7%
  Y8 = 21.1%
  Y9 = 21.4%
  Y10 = 21.8%

Filer-history margin distribution (19 FY, trimmed-10-90):
  p25 = 10.0%, p50 = 11.9%, p75 = 12.5%
  raw min = -19.3%, raw max = 18.6%
Path-stretch sub-counts:
  10 of 10 years above filer p75 (12.5%)
  9 of 10 years above filer max-ever (18.6%)
  Terminal/start ratio = 120%
Binding trigger = unprecedented-margin (drives the page badge)
            

7 · ROIC path construction

The capex heuristic compares latest-period CapEx ($343.8M) against the Normalized CapEx (3-yr mean) of $351.4M — mean of the last three annual CapEx values. When the latest is above 1.4× that mean and CapEx is at least 5% of revenue, we treat the filer as capital-intensive and mid-investment, hold ROIC flat for a 5-year harvest phase, and only then fade to terminal ROIC. The 3-yr mean does not feed the DCF directly — it only gates this flag.

Capex-heuristic inactive (latest CapEx 0.98× the 3-yr mean of $351.4M — below the 1.4× / 5%-of-revenue gates).
Fade from Y1: ROIC_t = ROIC₀ + (ROIC_terminal − ROIC₀) × (t / 10)
ROIC₀ = 25.3%; ROIC_terminal = 9.1%

ROIC by year:
  Y1 = 23.7%
  Y2 = 22.1%
  Y3 = 20.4%
  Y4 = 18.8%
  Y5 = 17.2%
  Y6 = 15.6%
  Y7 = 14.0%
  Y8 = 12.4%
  Y9 = 10.7%
  Y10 = 9.1%
            

7a · Reinvestment formula

The Damodaran growth-firm closure Reinvestment_t = ΔRevenue_t ÷ salesToCapital collapses to noise whenever EITHER the 3-year revenue change OR the 3-year net reinvestment is small relative to the revenue base. The model picks the most-honest formula via a 3-tier ladder: tier-1 standard sales-to-capital fires only when both signals carry magnitude AND the resulting ratio sits inside the typical 0.5–8 band; tier-2 substitutes a TTM (CapEx − D&A) ÷ Revenue ratio applied to each projection year's revenue (not its delta); tier-3 falls through to the ΔNOPAT ÷ ROIC closure when neither signal is usable.

Inputs:
  ΔRev_3y                          = $5.61B
  netReinvest_3y (CapEx − D&A)     = -$49.5M
  avgRevenue_3y                    = $18.80B
  TTM CapEx − D&A                  = -$34.5M
  TTM Revenue                      = $21.60B

Tier-1 gates (all three must clear):
  |ΔRev_3y| / avgRev_3y > 1.0%     29.85%         ✓ pass
  netReinv_3y / avgRev_3y > 1.5%   -0.26%         ✗ fail
  0.5 ≤ s2c candidate ≤ 8          5.322          ✓ pass

Tier-2 fires (gate failed: denominator). Substituting CapEx-of-revenue heuristic.
  capexOfRevenueRatio (raw)        = -0.16% — D&A > CapEx; floored at 0%
  capexOfRevenueRatio (used)       = 0.00%
  Reinvestment_t = Revenue_t × 0.00%
            

8 · Solver iterations

Each row is one configuration in the solver ladder; the "Solved margin" column is the result of bisecting the EBIT margin (up to 80 inner iterations) to match the EV target for that row's plateau / Y1 bump / phase. The solver sweeps Y1 growth bumps 0pp → +20pp across the plateau ladder inside the normal margin bracket, then — if nothing reconciles — repeats the same sweep in a widened margin band ([-10%, 80%]). The first feasible row is the one the page uses. If no combination reconciles, the page shows the row whose PV sits closest to the target EV so both levers are balanced.

9 · Terminal value derivation

NOPAT_{N+1}         = NOPAT_{10} × (1 + g_terminal)
                    = $10.31B × (1 + 2.5%)
                    = $10.57B

ΔNOPAT              = NOPAT_{N+1} − NOPAT_{10}
                    = $257.8M
Reinvestment_{N+1}  = ΔNOPAT / ROIC_terminal
                    = $257.8M / 9.1%
                    = $2.82B

FCF_{N+1}           = NOPAT_{N+1} − Reinvestment_{N+1}
                    = $10.57B − $2.82B
                    = $7.75B

Terminal value (TV) = FCF_{N+1} / (WACC − g_terminal)
                    = $7.75B / (9.1% − 2.5%)
                    = $116.84B

PV(TV)              = TV / (1 + WACC)^(10 − 0.5)
                    = $116.84B / 2.294
                    = $50.94B

10 · Reconciliation check (DCF PV vs. the market)

This isn't a fair value — it's the inverse check. The solver built the scenario so that DCF PV reproduces the current enterprise value; if the normal bracket worked the delta below is ~0 by construction. A non-zero delta only appears when the solver fell through to the widened margin band.

Σ PV(FCF_1..10) = $44.74B
+ PV(TV)          = $50.94B
= Enterprise value = $95.68B   (≈ EV target $96.69B by construction)
− Total debt      = $3.92B
+ Cash            = $0
− NCI             = $21.6M
= Equity value    = $91.73B
÷ Diluted shares  = 222.6M
= DCF PV / share  = $412.19

Market price      = $416.74
Reconciliation Δ  = −1.1%   (≈ 0 by construction — the solver anchored on this price)
