Lennox International
Lennox International, founded in 1895 in Marshalltown, Iowa and now based in Richardson, Texas, makes heating, ventilation, air conditioning and refrigeration (HVACR) equipment. It reports two segments: Home Comfort Solutions ($3,343 million of 2025 net sales) — furnaces, air conditioners and heat pumps sold under Lennox, Armstrong Air, Ducane, AirEase and other brands through its own Lennox Stores and dealers — and Building Climate Solutions ($1,852 million), which sells commercial rooftop units, VRF, refrigeration and service. 2025 sales slipped 3% to $5,195 million, but net income held at $806 million. Lennox sold its European businesses in 2023, bought HVAC parts makers Duro Dyne and Supco for $545 million in October 2025, and owns 49.9% of a joint venture distributing Samsung ductless products. It returned $173 million in dividends and $482 million in buybacks in 2025.

At a glanceFrom SEC data
Eight headline measures, each placed among the companies covered on this site.
- Revenue growthCAGRSmooths out year-to-year swings into "grew X% a year on average." Makes growth pace comparable across companies of very different sizes.
- 7.4%
- Operating marginOperating marginHow many cents of operating profit are left per dollar of revenue. Reflects pricing power and cost structure.
- 20.0%
- ROIC minus WACCROIC − WACC spreadThe difference between ROIC and WACC. Consistently positive implies value creation; consistently negative implies value destruction.
- +26.4 pts
- Net debt ÷ EBITDAEBITDAOperating income with D&A added back. A rough proxy for cash-generating power that’s less distorted by capital intensity, depreciation method, or financing/tax differences than net income.
- 1.2x
- Cash conversionOperating CF ÷ net income (cash conversion)How much of reported profit shows up as actual cash. 1x or higher means profit is backed by cash.
- 0.94x
- Dividend raisesDividend per shareTotal annual dividend paid per share (sum of all declared payments for the year).
- 5 of 5
- P/E todayP/EShare price ÷ EPS — how many years of current earnings the stock price represents. This site uses the period-end figure as reported in the filing.
- 16.7x
- Betaβ (beta)How much a stock moves, on average, for a 1% move in the overall market. Above 1 means more volatile than the market, which raises the return shareholders require. This site computes it from about 2.5 years (roughly 130 weeks) of weekly returns, built from Yahoo Finance daily prices, regressed against an S&P 500 ETF (SPY) as the market proxy, then applies the well-known long-run mean-reversion adjustment (0.67 × β + 0.33) as the WACC default.

Each marker shows where this company sits among the non-financial companies covered on this site, not all listed companies (left = lowest, right = highest). A high position is not automatically good — for net debt ÷ EBITDA, higher means more debt. Details and formulas are in the sections below and in How to read this.

- P/BP/BShare price ÷ book value per share. Below 1x means the market values the company below its accounting net worth. This site uses the closing price nearest the fiscal year-end and highlights sub-1x readings. today

- EV/EBITDAEV/EBITDAEnterprise value (≈ market cap + interest-bearing debt − cash) as a multiple of EBITDA — roughly, "how many years of EBITDA to buy the whole company."

- FCF yieldFree cash flow (FCF)Operating CF minus capital expenditures — cash generated by the business after funding its own investment, available for dividends, buybacks, acquisitions, or debt paydown.

“Today” uses the latest closing price (2026-11-04, Yahoo Finance daily closing prices) and shares outstanding at the last fiscal year-end. The rest of this page — including the financial table and ROIC vs. WACC — uses fiscal year-end prices. These are reference figures, not a judgment of whether the stock is cheap or expensive.

Revenue grew +7.4% a year over 5 years (strong growth)
From $3.63B in FY2020 to $5.2B in FY2025. The annualized rate (CAGR) makes it possible to compare growth pace across companies of different sizes.
- ▲
Operating margin improved: 13.2% → 20.0%
How much operating profit is left per $100 of revenue. It moved +6.9 points over 5 years — pricing power, cost control, and product mix all show up here.
- ▼
Equity ratio is 28.5% (relatively heavy reliance on debt)
The share of total assets funded by equity rather than debt. 50%+ is often read as low bankruptcy risk, though the right level varies by industry (real estate and leasing run lower, for instance).
- ▲
Free cash flow was positive in 6 of 6 years
Operating cash flow minus capital expenditures: the cash left over after funding the business’s own investment, available for dividends, buybacks, acquisitions, or debt paydown. A negative year can mean heavy investment, or weak core earnings — worth distinguishing.
- ▲
ROE averaged 97.8% over 6 years (latest: 75.8%)
How much profit was generated on shareholders’ equity. Roughly 10%+ is often cited as solid for a U.S. company, though this varies a lot by industry and capital intensity.

Is ROIC above WACC?From SEC data
ROIC (the return on money invested in the business) above WACC (the cost of raising that money) means the company is creating value. WACC is an estimate, so its assumptions can be adjusted below.
ROIC (FY2025)
36.0%
formulaoperating income × (1 − tax rate) ÷ invested capital × 100 *invested capital = interest-bearing debt + total equity (average of beginning/ending)
e.g.$1,041M × (1 − 19.5%) ÷ $2,331M × 100 = 36.0%
termsOperating income · Effective tax rate · Invested capital · Interest-bearing debt · Total equity
WACC (this site’s estimate)
9.53%
formulacost of equity × equity weight + cost of debt × (1 − tax rate) × debt weight
e.g.Equity weight: $16.9B ÷ ($16.9B + $1.39B) = 92.4%
e.g.Debt weight: $1.39B ÷ ($16.9B + $1.39B) = 7.6%
e.g.WACC: 10.1% × 92.4% + 2.9% × (1 − 19.5%) × 7.6% = 9.53%
termsCost of equity · Equity weight (E/(D+E)) · Cost of debt · (1 − tax rate) · Debt weight (D/(D+E)) · Market capitalization
How firm is this? With the equity risk premium ±1 point and beta ±0.2, WACC runs 7.8%–11.6% and ROIC − WACC runs +24.4 to +28.1 points. The sign holds across this range. This describes the latest year and does not predict future value creation.

Try different WACC assumptions
β and the equity risk premium are estimates with a real range of plausible values — move the sliders to check whether ROIC > WACC still holds. The risk-free rate starts at the 10-year Treasury yield on 2026-11-03 (U.S. Treasury).
Initial β: 0.94 (price-derived adjusted beta. Raw β 0.92, R² 0.16, 130 weeks)
formula0.67 × β + 0.33 (β = the slope of weekly stock returns regressed on weekly market returns)

What the price implies (DCF)From SEC data
A company's value can be written as its free cash flow divided by (cost of capital − perpetual growth). Working that backwards from the market's valuation shows how much growth the share price assumed — compared here with the company's actual past growth.
Growth the price implies (price on 2026-11-04)
4.9%
Perpetual FCF growth: g = r − FCF ÷ EV = 9.5% − 4.6%
Past FCF growth (FY2020–FY2025)
+3.7%
Compound annual rate, 5 years
Past revenue growth (FY2020–FY2025)
+7.4%
Compound annual rate, 5 years
Inputs (FY2025): free cash flow $639M (operating CF − capex); enterprise value $13.85B = market cap $12.5B (latest close, 2026-11-04) + debt $1.39B − cash and short-term investments $35M; r = WACC of 9.5% using this page’s default assumptions (β 0.94, risk-free 5.0%, market premium 5.5%).
Three WACC scenarios
The same calculation under cautious, base and optimistic cost-of-capital assumptions (risk-free rate fixed at the 10-year Treasury yield). Pick one to load it into the sliders below.
Try your own assumptions
V = FCF ÷ (r − g). It starts at the implied growth rate, where the theoretical value equals today’s enterprise value.
Theoretical enterprise value
$13.89B
FCF $639M ÷ (9.5% − 4.9%)
Theoretical ÷ actual enterprise value
1.00x
Above 1x: these assumptions value the business above the market did
How sensitive the answer is
Theoretical ÷ actual enterprise value for each combination of r and g.
| g \ r | 7.5% | 8.5% | 9.5% | 10.5% | 11.5% |
|---|---|---|---|---|---|
| 0% | 0.61x | 0.54x | 0.49x | 0.44x | 0.40x |
| 2% | 0.84x | 0.71x | 0.61x | 0.54x | 0.49x |
| 4% | 1.32x | 1.02x | 0.84x | 0.71x | 0.61x |
| 6% | 3.07x | 1.84x | 1.32x | 1.02x | 0.84x |
| 8% | — | 9.22x | 3.07x | 1.84x | 1.32x |
A simplified model for seeing what the market price assumes, not a forecast or a target price. It treats free cash flow as growing at one constant rate forever; the result swings widely with small changes in r and g, and is undefined when g reaches r. Free cash flow here is operating cash flow minus capex, which is after interest — a full DCF of enterprise value would use cash flow before interest. Market cap uses the latest close (2026-11-04) × shares at fiscal year-end; free cash flow and WACC inputs are from the latest fiscal year.

Who holds the sharesFrom SEC dataShow
How much of the stock large institutional investors report owning on SEC Form 13F, how much the directors and executive officers hold (and how much of the vote they control), and roughly how much is left for individual investors. Shown next to beta so the holder mix can be read alongside how much the stock swings.

We rely on our direct sales channel for a substantial portion of our revenue. Our direct-to-dealer network also creates a large installed base of HVACR equipment, and creates opportunities for longer term service, monitoring, solutions, and retrofit revenue. If we are unable to continue to execute our strategy, whether due to changes in economic conditions, a failure to anticipate changing customer needs, entry of new competitors into the low-barrier distribution business, or for any other reason, our revenue could decline, which could in turn adversely impact our product pull-through and our ability to grow revenue.
