Frequently Asked Questions

Is IEX stock undervalued or overvalued?
🔴 OVERVALUED

IEX trades at $195.30 vs. our DCF-derived intrinsic value of $126.27, implying -31% downside. Using a 10.0% WACC and 8.0% FCF growth assumption, the current price requires growth rates above our estimates to be justified. Even our bull case ($179.44) suggests limited upside.

What is IEX's intrinsic value?

Using a 5-year DCF model: Base FCF of $603M, projected at 8.0% 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 $1.37B net debt and dividing by 0.08B shares: Bear $86.51 | Base $126.27 | Bull $179.44. Current price $195.30 implies -31% to base case.

How is IEX's fair value calculated?

DCF Methodology:

① Project FCF years 1-5 using 8.0% 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 ($10.95B).

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: 18.2x.
