Frequently Asked Questions

Is LII stock undervalued or overvalued?
🟢 UNDERVALUED

LII trades at $533.25 vs. our DCF-derived intrinsic value of $609.56, implying +17% upside. At a 10.0% WACC and 20.0% projected FCF growth, the market appears to be underpricing the present value of LII's future cash flows. The bear case ($389.49) still suggests upside, providing margin of safety.

What is LII's intrinsic value?

Using a 5-year DCF model: Base FCF of $782M, projected at 20.0% 5Y CAGR (best of revenue, EPS, or FCF growth), discounted at 10.0% WACC, with 3.0% terminal growth. Terminal value calculated via Gordon Growth Model: TV = FCF₅ × (1+g) / (WACC−g). After deducting $1.07B net debt and dividing by 0.04B shares: Bear $389.49 | Base $609.56 | Bull $933.64. Current price $533.25 implies +17% to base case.

How is LII's fair value calculated?

DCF Methodology:

① Project FCF years 1-5 using 20.0% growth derived from 5-year historical CAGR (best of revenue, EPS, or FCF growth, with 8% floor and 25% cap).

② Calculate terminal value at year 5 using perpetuity growth model with g=3.0%.

③ Discount all cash flows to PV using WACC=10.0%.

④ Sum PV of explicit period + PV of terminal value = Enterprise Value ($22.90B).

⑤ Subtract net debt, divide by shares outstanding.

Sensitivity analysis available above—adjust WACC ±2% or growth ±3% to stress-test the valuation. Implied EV/FCF multiple: 29.3x.
