What is AYI's intrinsic value?

Using a 5-year DCF model: Base FCF of $533M, projected at 14.9% 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 $582M net debt and dividing by 0.03B shares: Bear $260.73 | Base $388.62 | Bull $569.95. Current price $320.82 implies +4% to base case.

How is AYI's fair value calculated?

DCF Methodology:

① Project FCF years 1-5 using 14.9% 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 ($12.88B).

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: 24.2x.
