đ Scenario Math, Done Right
From todayâs EV to 5-year outcomes - without fantasy.
Price targets anchored to vibes donât travel well. A durable framework starts at todayâs enterprise value (EVâ) and projects cash, not headlines. If FCF/share rises while the multiple doesnât need to, youâre compounding for the right reason. Scenario math forces discipline: define growth, margins, and a credible terminal multipleâthen see what falls out.
đ§± The three building blocks
You only need three levers (plus share count hygiene):
Revenue growth: the 5-year Rev factor = (1+g)^5
Cash conversion: FCF margin glides from today to Year-5 (Y5).
Terminal valuation: an EV/FCF(Y5) band that peers and quality justify.
Put simply: EVâ = FCFâ Ă (EV/FCF)â , where FCFâ = Revâ Ă Rev factor Ă FCF marginâ .Your Total Return (TR)=
đ§ź A simple 5-year model (with numbers)
Assume today: Revâ = $200m, FCF marginâ = 5% â FCFâ = $10m. Stock trades at EV/FCFâ = 60Ă â EVâ â $600m.
Model: Rev CAGR = 18% â Rev factor â 2.29; FCF marginâ
= 20%.
Then: FCFâ
â 200 Ă 2.29 Ă 20% = ~$91.5m.
Pick EV/FCFâ
= 25Ă (quality, but not heroic).
EVâ
â 25 Ă $91.5m = ~$2.29b.
TR â 2.29b / 0.60b â 1 â +281%; CAGR â ~31%/yr.
Note the shape: EV/Sales can fall while EV/FCF falls less, because FCF margin rises. Thatâs the glide you wantâcash, not rerating, drives returns.
đ/âïž/đ» Weight it like an owner
Define ranges, not dreams. Example (same starting point):
Bull (30%): Rev CAGR 22%, FCF marginâ 22%, EV/FCFâ 28Ă â TR ~+360%, CAGR ~35%.
Base (50%): Rev CAGR 16%, FCF marginâ 18%, EV/FCFâ 23Ă â TR ~+190%, CAGR ~24%.
Bear (20%) (constructive): Rev CAGR 10%, FCF marginâ 14%, EV/FCFâ 18Ă â TR ~+70%, CAGR ~11%.
Weighted expected â +214% total (â ~25%/yr). The bear still makes money because cash improvesâeven if growth slows and the terminal multiple is stingy.
đ§Ș Guardrails that keep you honest
Terminal sanity: EV/FCFâ above peer medians demands evidence (moat, NRR, pricing power). Otherwise cap it.
Bridge, not EBITDA: Reconcile EBITDA â OCF â FCF; if OCF < growth capex for two quarters, haircut margins.
Dilution hygiene: Model net shares +1â2%/yr unless you have proof otherwise; always track FCF/share, not just FCF.
Compression welcome: A good model survives EV/Sales compression because FCF/share climbs. If your IRR needs rerating, rewrite it.
đŻ Copy/paste template (work the numbers)
Input: Revâ, FCF marginâ
Choose: Rev CAGR, FCF marginâ , EV/FCFâ .
Compute: Rev factor, FCFâ , EVâ â TR, CAGR.
Build Bull/Base/Bear; weight 30/50/20; derive expected TR & CAGR.
Sanity-check against peers; adjust if OCF<capex or dilution >2%/yr.
Decision: Add if cash path prints two quarters; trim if multiple outruns cash; exit on broken bridge.
Anchor to todayâs EV, let FCF/share do the lifting, and make the terminal multiple earned, not imagined. Scenario math wonât predict the future - but it will stop you from paying for one you canât afford.
