27.3.1 Discounted Cash Flow (DCF) Analysis
Discounted Cash Flow (DCF) Analysis is a cornerstone of financial valuation, offering a structured approach to estimating the value of an investment based on its expected future cash flows. This method is essential for investors and financial analysts aiming to determine the intrinsic value of equity investments. In this section, we will delve into the intricacies of DCF analysis, covering key concepts such as free cash flow forecasting, discount rate calculation, terminal value estimation, and the application of DCF to derive intrinsic value.
Understanding DCF Analysis
At its core, DCF analysis involves projecting the future cash flows of an investment and discounting them back to their present value using an appropriate discount rate. This approach acknowledges the time value of money, a fundamental financial principle stating that a dollar today is worth more than a dollar in the future due to its potential earning capacity.
The general formula for DCF is:
$$
\text{DCF} = \sum_{t=1}^{n} \frac{\text{FCF}_t}{(1 + r)^t} + \frac{\text{Terminal Value}}{(1 + r)^n}
$$
Where:
 \( \text{FCF}_t \) is the free cash flow in year \( t \)
 \( r \) is the discount rate
 \( n \) is the number of years in the projection period
Forecasting Free Cash Flows
Accurate forecasting of free cash flows is pivotal to the success of a DCF analysis. Free cash flows represent the cash available to investors after accounting for capital expenditures and working capital needs. There are two primary types of free cash flows used in DCF:
Free Cash Flow to the Firm (FCFF)
FCFF is the cash flow available to all capital providers, both debt and equity holders. It is calculated as follows:
$$
\text{FCFF} = \text{EBIT}(1  \text{Tax Rate}) + \text{Depreciation and Amortization}  \text{Capital Expenditures}  \Delta \text{Net Working Capital}
$$
 EBIT: Earnings before interest and taxes.
 Depreciation and Amortization: Noncash expenses added back to earnings.
 Capital Expenditures: Investments in longterm assets.
 \(\Delta \text{Net Working Capital}\): Change in current assets minus current liabilities.
Free Cash Flow to Equity (FCFE)
FCFE represents the cash flow available to equity shareholders after accounting for debt obligations. It is calculated as:
$$
\text{FCFE} = \text{Net Income} + \text{Depreciation and Amortization}  \text{Capital Expenditures}  \Delta \text{Net Working Capital} + \text{Net Debt Issued}
$$
 Net Income: Profit after taxes and interest.
 Net Debt Issued: New debt raised minus debt repayments.
Determining the Discount Rate
The discount rate is a critical component of DCF analysis, reflecting the risk and opportunity cost of investing capital. The appropriate discount rate depends on the type of cash flow being valued.
Weighted Average Cost of Capital (WACC)
For FCFF, the discount rate is typically the Weighted Average Cost of Capital (WACC). WACC represents the average rate a company pays to finance its assets, considering both equity and debt financing.
Cost of Equity (r_e)
For FCFE, the discount rate is the cost of equity, which can be estimated using the Capital Asset Pricing Model (CAPM):
$$
r_e = R_f + \beta ( R_m  R_f )
$$
 \( R_f \): Riskfree rate, typically the yield on government bonds.
 \( \beta \): Measure of a stock’s volatility relative to the market.
 \( R_m \): Expected market return.
Calculating Terminal Value
Terminal value accounts for the value of cash flows beyond the projection period, often comprising a significant portion of the total valuation. There are two common methods for estimating terminal value:
Perpetuity Growth Model
This model assumes that cash flows grow at a constant rate indefinitely:
$$
\text{Terminal Value} = \frac{\text{FCF}_{n} \times (1 + g)}{k  g}
$$
 \( g \): Perpetual growth rate.
 \( k \): Discount rate.
Exit Multiple Method
This method applies a valuation multiple (e.g., EV/EBITDA) to a financial metric in the final projected year.
StepbyStep Example
To illustrate the DCF process, consider a hypothetical company with the following assumptions:
 Projected FCFF for the next five years: $100 million, $110 million, $121 million, $133 million, $146 million.
 WACC is 10%.
 Perpetual growth rate beyond year five is 2%.
Calculations
 Discount Each FCFF: Calculate the present value of each projected FCFF using the WACC.
$$
\text{PV of FCFF}_t = \frac{\text{FCFF}_t}{(1 + \text{WACC})^t}
$$
 Compute Terminal Value: Use the perpetuity growth model to estimate terminal value at the end of year five.
$$
\text{Terminal Value} = \frac{\text{FCF}_5 \times (1 + g)}{\text{WACC}  g}
$$
 Discount Terminal Value: Calculate the present value of the terminal value.
$$
\text{PV of Terminal Value} = \frac{\text{Terminal Value}}{(1 + \text{WACC})^5}
$$

Sum Present Values: Add the present values of the FCFFs and the terminal value to determine the enterprise value.

Subtract Net Debt: Deduct net debt to find the equity value.

Calculate Intrinsic Value Per Share: Divide the equity value by the number of shares outstanding.
Emphasizing Critical Concepts
Importance of Accurate Forecasts
Accurate forecasting is crucial, as small changes in assumptions can significantly impact the valuation. Analysts must carefully consider historical performance, industry trends, and economic conditions when projecting cash flows.
Sensitivity Analysis
Sensitivity analysis involves assessing how variations in key inputs, such as growth rates and discount rates, affect the valuation. This analysis helps identify the most critical assumptions and assess the robustness of the valuation.
Addressing Common Misconceptions
DCF is Too Complex or Unreliable
While DCF analysis can be complex, it provides a robust framework for valuation when conducted with care and reasonable assumptions. It is particularly useful for valuing companies with predictable cash flows.
Summary
Discounted Cash Flow (DCF) analysis is a methodical approach that considers the time value of money, offering a comprehensive framework for valuing investments. By forecasting free cash flows, determining appropriate discount rates, and calculating terminal value, investors can arrive at an intrinsic value for equity investments. This analysis is crucial for making informed investment decisions and understanding the true worth of a company.
