DCF Valuation Skill

Overview

I help you build Discounted Cash Flow (DCF) models to estimate the intrinsic value of companies. DCF is the gold standard for fundamental valuation used by investment banks, hedge funds, and professional investors.

What I can do:

• Build complete DCF models from financial data
• Calculate WACC (Weighted Average Cost of Capital)
• Project future free cash flows
• Estimate terminal value (Gordon Growth or Exit Multiple)
• Run sensitivity analysis on key assumptions
• Generate professional valuation summaries

What I cannot do:

• Guarantee accuracy of projections
• Account for unpredictable future events
• Provide investment recommendations
• Replace professional financial due diligence

How to Use Me

Step 1: Provide Financial Data

I need:

• Historical financials (3-5 years of revenue, EBITDA, capex, D&A)
• Current shares outstanding
• Current stock price (optional, for comparison)
• Industry/sector context

Step 2: Set Assumptions

Key assumptions to specify (or I'll use industry defaults):

• Revenue growth rates (Year 1-5)
• EBITDA margin trajectory
• Capex as % of revenue
• Working capital changes
• Terminal growth rate
• Discount rate (WACC)

Step 3: Choose Model Type

• Standard DCF: 5-year projection + terminal value
• Two-Stage DCF: High growth + stable growth phases
• Three-Stage DCF: Growth, transition, maturity phases

DCF Model Framework

Step 1: Project Free Cash Flow (FCF)

Unlevered Free Cash Flow (UFCF) =
    EBIT × (1 - Tax Rate)
  + Depreciation & Amortization
  - Capital Expenditures
  - Change in Net Working Capital

Step 2: Calculate WACC

WACC = (E/V × Re) + (D/V × Rd × (1 - Tc))

Where:
E = Market value of equity
D = Market value of debt
V = E + D (total value)
Re = Cost of equity (CAPM: Rf + β × Market Risk Premium)
Rd = Cost of debt
Tc = Corporate tax rate

CAPM Formula for Cost of Equity

Re = Rf + β × (Rm - Rf)

Where:
Rf = Risk-free rate (10-year Treasury)
β = Stock beta (systematic risk)
Rm - Rf = Equity risk premium (typically 5-6%)

Step 3: Calculate Terminal Value

Method A: Gordon Growth Model

Terminal Value = FCF(n+1) / (WACC - g)

Where:
FCF(n+1) = Final year FCF × (1 + g)
g = Terminal growth rate (typically 2-3%, ≤ GDP growth)

Method B: Exit Multiple

Terminal Value = EBITDA(n) × Exit Multiple

Common multiples by sector:
- Technology: 10-15x
- Healthcare: 8-12x
- Consumer: 6-10x
- Industrial: 5-8x

Step 4: Discount to Present Value

Enterprise Value = Σ [FCF(t) / (1 + WACC)^t] + [TV / (1 + WACC)^n]

Equity Value = Enterprise Value - Net Debt + Cash

Intrinsic Value per Share = Equity Value / Shares Outstanding

## Key Assumptions

### Revenue Projections
| Year | Revenue ($M) | Growth % |
|------|-------------|----------|
| Base (Current) | X,XXX | - |
| Year 1 | X,XXX | XX% |
| Year 2 | X,XXX | XX% |
| Year 3 | X,XXX | XX% |
| Year 4 | X,XXX | XX% |
| Year 5 | X,XXX | XX% |

### Margin Assumptions
| Metric | Year 1 | Year 5 | Rationale |
|--------|--------|--------|-----------|
| EBITDA Margin | XX% | XX% | [Reason] |
| Capex/Revenue | XX% | XX% | [Reason] |
| D&A/Revenue | XX% | XX% | [Reason] |

### WACC Calculation
| Component | Value | Source/Assumption |
|-----------|-------|-------------------|
| Risk-free Rate | X.X% | 10-Year Treasury |
| Beta | X.XX | Bloomberg/Calculated |
| Equity Risk Premium | X.X% | Historical average |
| Cost of Equity | XX.X% | CAPM |
| Cost of Debt | X.X% | Credit spread |
| Tax Rate | XX% | Effective rate |
| Debt/Total Capital | XX% | Current structure |
| **WACC** | **X.X%** | |

### Terminal Value
| Method | Value ($M) | As % of EV |
|--------|-----------|------------|
| Gordon Growth (g=X%) | X,XXX | XX% |
| Exit Multiple (Xx EBITDA) | X,XXX | XX% |
| **Selected** | **X,XXX** | **XX%** |

## Sensitivity Analysis

### WACC vs Terminal Growth Rate

| WACC ↓ / g → | 1.5% | 2.0% | 2.5% | 3.0% |

| Terminal Growth +0.5% | +XX% |
| Revenue CAGR +2% | +XX% |
| EBITDA Margin +2% | +XX% |

## Risks to Valuation

1. **Model Risk**: DCF highly sensitive to WACC and terminal growth assumptions
2. **Execution Risk**: Projected growth may not materialize
3. **Market Risk**: Multiple compression in downturn
4. **[Company-Specific Risk]**: [Detail]

Tips for Better Results

1. Provide historical data for more accurate projections
2. Be explicit about growth assumptions rather than using defaults
3. Specify the industry for appropriate comparables
4. Request sensitivity analysis to understand valuation range
5. Cross-check with multiples (P/E, EV/EBITDA) for sanity check

Limitations

• Garbage in, garbage out - results depend on assumption quality
• Terminal value often represents 60-80% of total value
• Does not account for optionality or real options value
• Assumes constant WACC throughout projection period
• Not suitable for early-stage unprofitable companies
