One-line thesis. Lennox is a genuinely high-quality HVAC franchise — 72% ROE, 33% gross margin, a fat replacement-demand tailwind from the refrigerant-regulation cycle — but FY25 revenue actually fell 2.7%, the residential segment is still working through a construction downturn, and at 26× trailing / 23× forward the stock already prices in the recovery; we rate it Watch and would want either a cheaper entry or evidence the residential cycle has decisively turned.
Lennox makes furnaces, air conditioners, and heat pumps for homes, plus the cooling and refrigeration systems that keep stores, restaurants, and warehouses running. It is a very well-run, very profitable company: for every dollar of sales it keeps about 33 cents as gross profit, and it earns extraordinary returns on the money invested in the business.
The catch: the stock is not cheap, and the business is cyclical — it rises and falls with home building and big-ticket replacements. Last year sales actually shrank a little because new-home construction was weak. The stock has already climbed a lot on hopes of a rebound, so you are paying a full price for a recovery that hasn't fully shown up yet. Our verdict is Watch — a great company, but wait for a better price or clearer proof the turn is real.
Here's what our three scores mean in everyday terms:
The one big worry: if home building and replacement demand stay soft, the residential half of the business keeps struggling — and there's little room in the price for disappointment.
Solid = price · dashed = 50-day average · dotted = 200-day average · amber = 52-week high/low. Price above both averages is an uptrend.
The shaded band widens when the stock gets more volatile. Riding the upper edge = strong momentum (sometimes stretched); the lower edge = weak / potentially oversold.
Above 70 (red band) = overbought, below 30 (green band) = oversold. Currently 64.
Blue crossing above amber (bars flip green) = momentum turning up; below (bars red) = turning down. Bar height = the size of that gap.
Solid = LII · 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.
Darker bars = actual results, brighter = analyst estimates. Taller bars to the right = expected growth.
Every claim reconciles to a real claim_id in the Synthos knowledge base — this is the evidence the verdict is built on, not vibes. Management (the company itself) is shown but half-weighted; one cautionary voice is included on purpose.
Lennox International (NYSE: LII), founded 1895 and headquartered in Richardson, TX, is a global manufacturer and distributor of heating, ventilation, air conditioning (HVAC) and refrigeration systems. It sells to homeowners (through contractors and its own parts-and-supplies stores) and to light-commercial and industrial customers. Fiscal year ends December 31. CEO Alok Maskara.
The company now reports two segments (it folded the old standalone Refrigeration and renamed the two survivors during 2025):
Revenue mix (FY2025, from filings):
The two structural tailwinds worth naming: (1) the refrigerant-regulation replacement cycle (the shift to A2L / low-GWP refrigerants forces equipment turnover), and (2) bolt-on M&A (the Duro Dyne and Supco acquisitions, integrated in 2025) that adds ~4 points of revenue growth.
There is no expert coverage of Lennox in the Synthos knowledge base. total_claims = 0; there are zero net-bullish voices and zero cautionary voices. Nothing in this note rests on a distilled expert claim, and — per the Synthos house standard — we will not manufacture conviction where none exists.
What that means for the reader: this verdict is entirely fundamentals- and quant-driven — built from the FMP financials, analyst estimates, the company's own SEC guidance (§9, half-weighted), and our scoring model. The Street's own view is a Hold (10 Buy / 16 Hold / 4 Sell), which is consistent with our Watch. Treat the absence of KB conviction as itself a signal: this is not a name any tracked Synthos expert is currently pounding the table on, in either direction.
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) | 6 · Moderate-High | Financially a cash machine (72% ROE, 1.64× net-debt/EBITDA, 20× interest coverage), but it's a cyclical at 26× trailing / 23× forward, beta 1.19, RSI 70 (near-overbought), and equity is thin (huge buyback-driven treasury stock). Little valuation cushion. |
| Growth Quality | 6 · Good | 33% gross / 22% EBITDA margin and elite returns on capital (ROIC 24%, ROCE 34%) are top-tier — but revenue fell 2.7% in FY25 and forward EPS CAGR is only ~10%. Quality yes; growth only middling. |
| Exponential Potential | 3 · Low | Housing/replacement cyclical with a finite North-American TAM; growth is decelerating, not accelerating. A steady compounder, structurally 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.
| Case | Key assumptions | Fair value |
|---|---|---|
| Bull | Residential cycle turns decisively; refrigerant replacement + Building Climate national-account wins drive mid-teens EPS growth; FY27E EPS beats to ~$29 (vs $26.6 cons); market pays a peak-cycle ~26×. | ~$755 (+32%) |
| Base (our anchor) | Estimates roughly hit — FY27E EPS ~$26.6; a high-quality but cyclical HVAC compounder earns a ~23× exit multiple. | ~$610 (+7%) |
| Bear | Housing stays soft, residential volumes keep falling, inflation/absorption pressure margins; FY27E EPS misses to ~$23; multiple de-rates to a mid-cycle ~17×. | ~$390 (−32%) |
Synthos fair value = the base case, ~$610 (+7%), with the full $390–$755 span as the honest range. This sits modestly above the Street's $556 consensus but the upside is thin and the downside is real — which is exactly why the verdict is Watch, not Buy. This is a tracked call — the Forecaster Scorecard grades it once it matures.
Synthos separates compounders (durable high returns on capital) from exponentials (accelerating, multi-baggers-from-here). LII is a high-quality compounder with essentially no exponential profile:
Exponential Potential: Low (3/10). Own LII, if at all, for durable ~10% earnings compounding + a fat dividend/buyback, not for a fast multibagger. Honest framing: this is a Core-quality cyclical, categorically not a Degen-tier or next-exponential name.
Lennox is not cheap, but not egregiously expensive either: 26× trailing EPS, 4.1× sales, 18.7× EV/EBITDA, 30× P/FCF. The bull's defense is that EPS out-grows the multiple: on live consensus the forward P/E is 23× (FY26E) → 21× (FY27E) → ~15× (FY30E) — so the multiple compresses if estimates hit. But two honest caveats temper that:
1. The estimate path is lumpy — consensus pencils an EPS dip in FY29 before FY30 recovers, so the smooth "grow into the multiple" story is not clean.
2. This is a cyclical — paying 26× trailing near what looks like a cycle-recovery bet leaves little margin if housing disappoints; cyclicals de-rate hard when the cycle rolls.
A fair mid-cycle multiple for a high-ROIC HVAC name is ~20–23× forward. Applied to FY27E ~$26.6, that anchors our ~$610 base-case fair value (+7%). Street targets (context): consensus $556, high $650, low $450 — our base sits just above consensus. The FMP letter grade is B (overall score 3/5), dinged specifically on debt-to-equity (1/5) and P/E (2/5) — consistent with "great returns, full price." Not a value buy; a quality-cyclical-at-full-price that we'd rather buy on a pullback.
Lennox's moat is real but ordinary-industrial, not wide: (1) a strong brand and installed base in North American residential HVAC, monetized through a captive parts-and-supplies distribution network that drives high-margin replacement/aftermarket revenue; (2) scale and manufacturing efficiency in a consolidated oligopoly; (3) contractor relationships and national-account service in commercial. The offsetting reality: HVAC equipment is a replacement-driven, regulation-cycle, weather-and-construction-sensitive category with capable competitors (Carrier, Trane, Daikin/Goodman) — pricing power is real but bounded, and switching costs sit with contractors more than the OEM.
Peer set (FMP-supplied, market cap): Watsco $16.7B (WSO — the closest HVAC-distribution comp), Carlisle $14.8B, Masco $16.7B, Pentair $12.4B, Snap-on $21.3B, Builders FirstSource $9.1B, AECOM $8.7B, C.H. Robinson $22.4B, Expeditors $21.9B, FTAI Aviation $25.4B. Note: the FMP peer list skews to broad "Industrials/Construction" and includes several non-HVAC names (logistics, tools); the truest read-across is WSO (Watsco) for HVAC distribution and Carrier / Trane (not in this list) for equipment. Against WSO and the building-products peers, LII carries the best returns on capital and the richest quality profile, which the market recognizes with a premium multiple.
- Full-year 2026 revenue growth ~8% (including ~4 points from completed acquisitions).
- Full-year 2026 EPS $23.50–$25.00 (maintained).
- Full-year 2026 free cash flow $750M–$850M.
- Management's narrative: residential ("Home Comfort") end-markets are stabilizing — Q1 revenue −10% but a sequential improvement from −21% in Q4'25; commercial ("Building Climate") organic +26% with strong national-account and emergency-replacement activity. CEO Maskara frames the strategy as "differentiated growth and bolt-on M&A."
- Honest weighting: this is management talking its own book (half-weight). The guidance reads as a genuine earnings release (revenue, EPS range, FCF range, segment detail) — not boilerplate — so it is usable, but the residential "stabilizing" claim is the thing to verify against the Q2 print.
Thesis tripwires (what would change the call): residential volumes deteriorating rather than stabilizing (would push toward the bear case); EPS guidance cut below the $23.50 floor; net-debt/EBITDA rising materially above ~2× on debt-funded M&A; or, conversely, a decisive residential turn + a pullback in the multiple (which would flip Watch → Buy).
Watch. Lennox is a genuinely high-quality business — 72% ROE, 33% gross margin, 24% ROIC, a fat replacement/aftermarket franchise, and management guiding to ~8% revenue growth and $23.50–$25.00 EPS in 2026. But three things hold us at Watch rather than Buy: (1) valuation — 26× trailing / 23× forward on a cyclical leaves little margin for error; (2) the cycle isn't confirmed — FY25 revenue fell, residential is still down double digits, and the "stabilizing" story needs the Q2 print to prove it; (3) the entry is technically stretched (RSI 70, a 12-month laggard bouncing). There is no expert conviction in the KB to lean on, and the Street itself is a Hold. Our base-case fair value (~$610, +7%) simply doesn't offer enough upside to justify chasing here.
