The Overview
Wabtec makes the brakes, control systems, and locomotives that keep freight trains and subways running — a 150-year-old business (it started as George Westinghouse's air brake company in 1869). Roughly 72% of sales are Freight (locomotives, braking, digital rail for the big railroads) and 28% is Transit (subways, light rail, buses). A big chunk of revenue is aftermarket — parts and service on trains already running — which is steady, recurring, high-margin money.
Is the stock cheap or expensive? Expensive. You pay about 37 dollars for every 1 dollar of last year's profit, which is a rich price for a company growing sales in the mid-to-high single digits. The business is good; the price is full. That is why our verdict is Watch — a great company we would rather buy on a dip than chase here.
Here is what our three scores mean in everyday terms:
- Downside Risk 5/10 (middle of the road). The stock is steady (it doesn't swing much) and the company pays its bills easily — but it borrowed a lot for a recent acquisition, and a rich price means a stumble would hurt.
- Growth Quality 6/10 (good, not great). Sales and profits are growing at a healthy clip and profit margins are slowly improving, but this is a mature industry, so growth is dependable rather than explosive.
- Exponential Potential 3/10 (low). Trains are a slow-growth business. Wabtec will likely keep compounding steadily for years, but it is not going to double or triple quickly.
The one big worry: freight rail is cyclical — when the economy slows and fewer goods move by train, orders soften. Pair that with the high price you pay today, and a slowdown could hit the earnings and the valuation at the same time.
Putting a number on it: our fair-value estimate is $268 against a current price of $292.23 — a premium price for a business we still like.
Our summary metrics
Low beta (0.94) & investment-grade, but 2.8× net-debt/EBITDA post-Evident deal and 37× trailing on a cyclical.
~8% fwd revenue / ~15% fwd EPS CAGR, margins grinding up, but modest ROIC (~7%) and a mature end market.
Decelerating single-digit top line, $44B cap in a slow-growth rail TAM — a compounder, not an exponential.
What does “fair value” mean?
Fair value is Synthos’s estimate of what one share is worth today, based on our model of the company’s future cash generation and the risks to it. It is not a price target or a prediction of where the stock trades next quarter — it’s the price where we think risk and reward are balanced. Above it, you’re paying for outcomes better than our base case; below it, the market is offering a margin of safety.
The model’s inputs and weightings are proprietary — they’re the product. What we publish is the output, plus an independent, public-math cross-check further down the page (“Check our number”) so you can judge it for yourself.

What the experts actually said
No independent expert claims in the Synthos knowledge base yet for WAB — this dive is fundamentals- and technicals-driven, not panel-driven.
Price & moving averages 12 months · 50 & 200-day averages · 52-week range
Solid line = price · dashed line = 50-day average · dotted line = 200-day average · the two thin horizontal lines mark the 52-week high and low. Price above both averages is an uptrend.
Data summary: last close $292.23, 3% above the 50-day average ($283), 16% above the 200-day average ($252) — an uptrend. 4% below the 52-week high of $306, 57% above the 52-week low of $186.
Bollinger Bands 20-day average ± 2 standard deviations
The shaded band widens when the stock gets more volatile. Riding the upper edge = strong momentum (sometimes stretched); the lower edge = weak / potentially oversold.
Data summary: price $292.23 is currently inside the band (band $291–$302).
RSI (14) momentum gauge · 0–100
Above 70 (overbought zone, shaded) = overbought, below 30 (oversold zone, shaded) = oversold. Currently 50.
MACD 12 / 26 / 9 · trend & momentum
The MACD line crossing above the signal line (bars flip to the up color) = momentum turning up; crossing below (bars flip to the down color) = turning down. Bar height = the size of that gap.
Data summary: MACD is currently below its signal line by 1.19, negative momentum.
Relative performance vs S&P 500 & its sector (XLI (sector)), set to 100 a year ago
Solid = WAB · dashed = S&P 500 · dotted = XLI (sector). A rising line means it is beating that benchmark — the sector line shows whether it is a leader or laggard within its own group.

Key stats an RIA wants
1. What it is
Wabtec (NYSE: WAB) — Westinghouse Air Brake Technologies — is a ~$44.5B market-cap global supplier of equipment, systems, digital solutions, and aftermarket services to the freight rail and urban transit industries. Headquartered in Pittsburgh, founded 1869, ~29,500 employees. Fiscal year ends December 31. The 2019 merger with GE Transportation transformed it into the dominant Western locomotive and rail-technology OEM. In FY25 it closed the ~$2.5B Evident (Inspection Technologies) acquisition (see the cash-flow and balance-sheet steps below), extending it into industrial inspection/NDT.
The business runs in two segments:
- Freight (72% of FY25 revenue): new and overhauled locomotives, braking, positive train control (PTC), signaling, digital/electronics, freight-car components, plus a large parts-and-service aftermarket. Customers: Class I railroads, leasing firms, OEMs.
- Transit (28% of FY25 revenue): components and services for subways, light rail, regional/high-speed trains, and buses — doors, HVAC, brakes, pantographs, accessibility. Customers: public transit agencies and municipalities.
Revenue mix (FY2025, from filings):
- By segment: Freight $8.04B (72%) · Transit $3.13B (28%). Both grew in FY25 (Freight +7.6%, Transit +7.3%).
- By geography (top markets): United States $5.37B (48%) · India $699M · Other Europe $663M · Canada $555M · South America $513M · Australia/NZ $453M · Kazakhstan/Russia/CIS $431M · France $419M · Germany $379M. The base is US-led but genuinely global (~52% ex-US), which diversifies demand but adds FX and geopolitical exposure (Russia/CIS $431M).
2. The expert thesis
There is no expert coverage for WAB in the Synthos knowledge base. total_claims = 0, net_bullish_voices = 0. None of the tracked expert voices in our panel have made a traceable, distilled claim on Wabtec.
Per house standard, we do not fabricate conviction: with zero claim_ids to cite, this note carries no KB-derived conviction, and the verdict is entirely fundamentals- and quant-driven off the FMP financials, analyst estimates, and management's own guidance. Treat the absence of expert coverage as an honest data gap, not a negative signal — it simply means the crowd of voices we track has not weighed in. The Street sell-side, by contrast, is constructive (21 Buy / 12 Hold / 1 Sell, $305 consensus target), which we show in §6 as context, not as our anchor.
3. Synthos scores & the Bull / Base / Bear cases
The one-glance judgment — three scores, 0–10, each anchored to real metrics (not probabilities we can't honestly calibrate):
| Score | 0–10 | The read |
|---|---|---|
| Downside Risk (lower = safer) | 5 · Moderate | Low beta 0.94, investment-grade, interest coverage 7.4×, shallow −7% drawdown — but net-debt/EBITDA 2.8× after the Evident deal, 37× trailing GAAP EPS, and freight-rail cyclicality cut the other way. |
| Growth Quality | 6 · Good | ~8% forward revenue CAGR and ~15% forward EPS CAGR, margins grinding higher (EBITDA margin ~20%, adj. operating margin ~22%), record $9.25B backlog — but only ~7% ROIC and a mature end market cap the quality. |
| Exponential Potential | 3 · Low | Single-digit, decelerating top line in a slow-growth rail TAM; a $44B cap with no acceleration is a steady compounder, not a multibagger. |
The three cases (our own scenario model — assumptions shown; each target is a ~12–18-month fair value). We deliberately do not attach probabilities: the base case is by definition the expected path, so a weighted blend would just restate it with false precision. Instead the cases bound the range, and the scores above summarize them. (EPS figures below are adjusted/consensus basis — WAB's GAAP EPS runs meaningfully below adjusted; e.g. FY25 GAAP EPS $6.83 vs adjusted ~$8.97 consensus.)
| Case | Key assumptions | Fair value |
|---|---|---|
| Bull | Backlog converts faster; margins expand on Integration 2.0/3.0 synergies + Evident; buybacks continue. FY27E adj. EPS beats to ~$13 (vs ~$12.15 cons); multiple holds a premium ~25×. | ~$330 (+26%) |
| Base (our anchor) | Estimates roughly hit — FY26E ~$10.62, FY27E ~$12.15 adj. EPS; a steady mid-teens compounder earns a ~22× forward multiple on FY27E. | ~$268 (+2%) |
| Bear | Freight traffic rolls over; a rail-capex down-cycle; tariff/cost pressure squeezes margin; multiple de-rates on a cyclical to ~16× on ~$12.15. | ~$200 (−24%) |
Synthos fair value = the base case, ~$268 (+2%), with the full $200–$330 span as the honest range. Our base sits below the Street's $305 consensus because we apply a more conservative cyclical multiple (~22× vs the Street's implied ~25×) and give weight to the deceleration and the leverage step-up. Note the narrow Street band ($291–$318) signals sell-side agreement that upside is limited from here. This is a tracked call — the Forecaster Scorecard grades it once it matures.
4. Exponential Potential
Synthos separates compounders (durable high returns on capital) from exponentials (accelerating, multi-baggers-from-here). WAB is a solid compounder with low exponential potential:
- Forward growth: revenue CAGR FY25→FY28E ~8.0% ($11.17B → $14.06B); adj. EPS CAGR ~15% (~$8.97 → ~$13.60) as margins expand and buybacks shrink the share count.
- Acceleration (the 2nd derivative) is negative: revenue growth was +7.5% (FY25) and consensus has it +10.9% (FY26E, lifted by the Evident deal) → +7.1% (FY27E) → +6.0% (FY28E) → and estimates actually dip in FY29E ($13.65B, thin coverage). Strip out the acquisition and organic growth is mid-single-digit. This is not a name where growth is speeding up. Per our flagship philosophy we pick forward next-exponentials over trailing compounders — WAB is firmly a compounder.
- Room to run: the freight-rail + transit equipment TAM is large in absolute dollars but grows with GDP/industrial activity, not exponentially. At $44B market cap in a mature, consolidated industry (WAB is already the Western leader), there is no law-of-large-numbers headwind like a megacap, but there is also no structural demand inflection to power a 3–5×.
- Reinvestment runway: capex is light (~$260M, ~2.3% of sales) and FCF is strong (~$1.5B FY25), so the model is a cash-return compounder (dividends + buybacks + tuck-in M&A) rather than a reinvestment-for-hypergrowth story.
Exponential Potential: Low (3/10). Own WAB — if you own it — for durable ~10–15% total-return compounding (mid-single-digit revenue + margin + buyback + ~0.4% dividend), not for a fast multibagger. A small, accelerating rail-tech disruptor would score 7–9 here; WAB is the incumbent, and that shows in the score.
5. Financials (real numbers — FMP annual/quarterly)
- Revenue: FY25 $11.17B, +7.5% (FY24 $10.39B, +7.3% on FY23 $9.68B). Steady mid-to-high-single-digit growth; the multi-year path 2021 $7.82B → 2025 $11.17B is a ~9% CAGR (helped by M&A).
- Quarterly trajectory: Q1'25 $2.61B → Q2 $2.71B → Q3 $2.89B → Q4 $2.97B → Q1'26 $2.95B (+13.0% YoY, Evident-aided). Growth is solid but not accelerating on an organic basis.
- Margins (grinding up — the real story): gross 33.8% TTM (up from ~28% in 2020), EBITDA margin ~20% TTM, operating ~16% GAAP / ~22% adjusted, net 10.5% TTM. The multi-year margin expansion from synergies (Integration 2.0/3.0) is the core quality signal.
- Earnings: GAAP net income $1.17B FY25 (EPS $6.83 diluted); adjusted EPS runs higher (~$8.97 consensus basis). GAAP EPS grew from $2.17 (2020) to $6.83 (2025) — a ~26% CAGR off a low base as the GE Transportation deal matured.
- Cash flow: operating CF $1.76B, capex −$260M, FCF ~$1.5B FY25 (FCF margin ~13.4%, ~93% of operating CF). High-quality cash conversion. Note FY25 investing was −$2.75B driven by the −$2.5B Evident acquisition, funded largely by +$1.48B new debt.
- Balance sheet: total debt $5.54B, cash $789M, net debt $4.75B → net-debt/EBITDA ~2.8× (up from ~1.6× pre-deal). Interest coverage 7.4×, current ratio ~1.0. Goodwill + intangibles are $14.1B (64% of assets) — a legacy of the GE deal, so tangible book is negative. Leverage is manageable but the acquisition meaningfully raised it; deleveraging is now a watch item.
6. Valuation — priced in or room?
WAB is not cheap on any lens. Trailing 37× GAAP EPS (or ~29× on adjusted), EV/EBITDA 22×, EV/Sales 4.4×, P/B 4.0×, FCF yield ~3.4%. The bull's defense is the forward multiple compresses as EPS grows: on consensus adjusted EPS the forward P/E is ~25× (FY26E) → ~22× (FY27E) → ~19× (FY28E). But the PEG is unflattering — trailing PEG ~3.4×, forward PEG ~2.6× — because you are paying a growth multiple for single-digit revenue growth. For a cyclical industrial, 22× forward is a full price that assumes the margin-expansion and backlog-conversion story keeps executing flawlessly.
Street targets (context, not our anchor): consensus $305 (high $318, low $291) — implying ~16% upside from $262, on ~25× FY27E. We are more conservative: our ~$268 base applies a ~22× cyclical-appropriate multiple and reflects the deceleration + leverage step-up. The tight $291–$318 Street band itself says the sell-side sees limited room. Verdict: fairly-to-fully valued; a quality name to buy on weakness, not to chase at 37× trailing.
7. Technicals (from the tech block)
- Trend: neutral. $262.19 sits below the 50-DMA ($265.1) but above the 200-DMA ($234.7), with the 50 still above the 200 — a mild consolidation within a longer uptrend, not a breakdown.
- Location: −7.2% off the 52-week high ($282.45), +41% off the 52-week low ($185.65). Max drawdown from peak is a shallow −7.2% — this is a low-volatility name.
- Momentum: RSI(14) 50 — dead neutral, neither overbought nor oversold. MACD +1.27 (marginally positive).
- Relative strength: WAB +25.2% 12-mo vs SPY +20.6% (modest outperformance) but vs QQQ +30.3% it lagged tech; +21% 6-mo (vs SPY +8.4%) is the stronger window, while +2.4% 3-mo (vs SPY +13.7%) shows it has stalled recently.
- Read: technicals are neutral-to-slightly-cooling — the stock has flattened after a strong 6-month run and sits just below its 50-DMA. No urgency to buy; a pullback toward the 200-DMA (~$235) would be a materially better risk/reward entry consistent with the Watch verdict.
8. Moat & competitive position
Wabtec's moat is real and multi-layered: (1) installed-base lock-in — an enormous global fleet of locomotives and rail assets that generates decades of high-margin aftermarket parts and service revenue; (2) scale and consolidation — post-GE-Transportation, WAB is the dominant Western freight-locomotive and rail-tech OEM, with switching costs, safety/regulatory certification barriers (PTC, signaling), and a broad product catalog rivals can't easily match; (3) long-cycle backlog visibility — a record $9.25B 12-month backlog (up 12.8%) and multi-year backlog up 38% give unusual revenue visibility for a cyclical. The competitive frame is an oligopoly (Wabtec, Knorr-Bremse, Siemens Mobility, Alstom, Trinity/Greenbrier in freight cars). The main threats are freight-rail cyclicality, decarbonization capex uncertainty (battery/hydrogen locomotives), and pricing pressure on new-build.
Peer set (FMP's list — note it is broad "industrials," not pure rail peers; market cap): Comfort Systems (FIX) $61B, Rocket Lab (RKLB) $58B, HEICO (HEI) $50B, Old Dominion (ODFL) $45B, United Airlines (UAL) $43B, EMCOR (EME) $34B, Ingersoll Rand (IR) $32B, Otis (OTIS) $28B, Xylem (XYL) $28B, Verisk (VRSK) $25B. WAB's truest comps (Knorr-Bremse, Alstom, Siemens Mobility) are non-US and not in this list — a gap worth flagging. Against this diversified-industrial set, WAB's ~20% EBITDA margin and mid-single-digit organic growth are middle-of-the-pack; it trades at a premium justified only by moat durability and backlog visibility.
9. Management, capital allocation & guidance
- Leadership: Rafael Santana (President & CEO), John Olin (CFO). The team has a credible multi-year record of margin expansion via the Integration 2.0/3.0 cost programs and portfolio optimization since the GE deal.
- Capital allocation: balanced — ~$1.5B FCF deployed across a growing dividend (yield ~0.4%, payout only ~15% — plenty of room to grow), buybacks ($223M repurchased FY25, $1.1B in FY24), and M&A (the ~$2.5B Evident deal in FY25). The leverage step-up to 2.8× net-debt/EBITDA to fund Evident is the main capital-allocation watch item; deleveraging cadence matters.
- Insider activity: the most recent filings (June 2026) show routine CEO Rule-10b5-1 sales by Rafael Santana (small tranches, ~260–264/share) plus a July equity award to an officer — normal diversification and comp, no alarming discretionary-sell cluster in the sampled window.
- Management's own guidance (half-weighted — their own book): the Q1'26 earnings release (SEC 8-K, filed 2026-04-22) is a real earnings presentation. Management highlighted: Q1'26 sales $2.95B (+13.0%), adjusted EPS $2.71 (+18.9%), adjusted operating margin 21.9% (+0.2pt), record backlog $9.25B (12-month +12.8%, multi-year +38.1%), and reaffirmed strong momentum with a 5-year outlook and continued cash conversion (Q1 operating cash flow at ~40% conversion, seasonally low). They also flagged tariff headwinds as a margin risk they are offsetting. Treated as half-weight — this is management talking its own book, but the backlog and margin numbers are auditable and corroborate the growth-quality score. No specific full-year revenue/EPS dollar guidance was reproduced in the fetched text beyond the reaffirmed multi-year framework.
10. Catalysts & what to watch
- Next earnings: 2026-07-22 (Q2'26; Street EPS $2.63, revenue ~$3.07B). Watch organic (ex-Evident) revenue growth, adjusted operating margin vs the 21.9% Q1 mark, backlog direction, and any full-year guidance revision.
- Backlog conversion: the $9.25B 12-month / multi-year-up-38% backlog is the bull's foundation — a stall or cancellation would be the first crack.
- Freight rail traffic & Class I capex: the cyclical demand signal; carload/locomotive-fleet trends and railroad capital budgets.
- Evident integration & deleveraging: synergy delivery and net-debt/EBITDA trending back toward ~2×.
- Tariffs/input costs: management flagged tariff headwinds; watch whether pricing/productivity keeps offsetting them.
- Decarbonization: progress (or slippage) on battery/hydrogen/next-gen locomotives as a long-term demand driver.
Thesis tripwires (what would change the call): two consecutive quarters of organic revenue deceleration or backlog decline; adjusted operating margin rolling over; leverage failing to trend down; or a freight-traffic recession signal. Any of these tilts Watch → Avoid. Conversely, a pullback to the low-$200s (near the 200-DMA) with backlog intact tilts Watch → Buy.
11. Key risks
- Cyclicality (structural): freight rail is tied to industrial/goods activity; a recession cuts locomotive orders, new-build, and — with a lag — aftermarket. The current multiple leaves little room for a down-cycle.
- Valuation / de-rating: 37× trailing GAAP (22× EV/EBITDA) on single-digit organic growth means multiple compression is a real risk if growth or margins disappoint.
- Leverage step-up: net-debt/EBITDA rose to ~2.8× to fund Evident; integration missteps or a downturn would make that heavier.
- Goodwill/intangibles = 64% of assets (negative tangible book): impairment risk if acquired-business returns disappoint.
- Geopolitical/FX: ~52% ex-US revenue including $431M Kazakhstan/Russia/CIS exposure and emerging-market end-markets.
- No expert coverage: the Synthos KB has zero traceable claims on WAB — we lack the independent-analyst breadth that would raise conviction either way, so the call leans harder on quant and management's (self-interested) guidance.
12. Verdict, position sizing & monitoring
Watch. Wabtec is a genuinely high-quality, wide-moat industrial compounder — record backlog, steadily expanding margins, strong FCF, disciplined capital allocation, mid-teens forward EPS growth. The problem is price, not quality: at 37× trailing GAAP EPS (~25× forward), a cyclical, single-digit-organic-growth business is priced for continued flawless execution, and our base-case fair value (~$268) sits essentially at the current $262 and below the Street's $305. That is a hold-quality, not a buy-here, setup.
- Sizing: watch-list first. If an investor wants the exposure, a small ~1–2% cyclical-industrial satellite, scaled in on weakness (target the 200-DMA ~$235 or lower), not a chase at highs.
- Monitoring: re-underwrite on the §10 tripwires; formal re-score each earnings print. A meaningful pullback with backlog intact would upgrade this to Buy — Tactical.
- Single biggest risk: freight-rail cyclicality colliding with a full multiple — a traffic/backlog stall would hit earnings and the P/E together.
