DRAFT – Presentation Materials are Preliminary, Confidential and Subject to Further Revisions P R O J E C T T E M P E S T DCF Methodology Overview ($ in billions except per share values unless otherwise stated)  DCF analyses are influenced by many factors, some of which are relatively static, while others fluctuate with the market. The key inputs into the Enterprise Value of a company implied by DCF analysis are:  The company’s cash flows through the end of the forecast period  The terminal value (TV) of the company at the end of that forecast period, beyond which annual cash flow forecasts are no longer available and the value of the company at that point in time must be calculated in aggregate, not based on cash flows in each year  The present value of those forecast cash flows and TV, calculated by discounting them at the weighted average cost of capital (WACC)  In situations where the company has not yet reached mature, steady - state growth by the end of the forecast period, TV is sometimes calculated by applying a terminal multiple to the company’s financials at that time (e.g., to EBITDA) based on comparable company multiples, and the present value of that TV can make up much of the overall DCF valuation (in this analysis, well over 90%)  WACC is calculated based on the risk - free rate, unlevered beta, levering factor, equity risk premium, cost of debt and the tax rate  Of those, the following are typically affected by real - time market data : risk - free rate (based on the yield on 10 - Year government bonds) and unlevered beta (calculated based on the beta and leverage of comparable companies and of the company itself, to which stock price is an input)  In this analysis, terminal multiple is calculated based on the trading multiples (in this case EV/EBITDA) of comparable companies; EV is affected in real - time by the stock prices of those companies, and EBITDA is affected as and when research analysts update their forecasts  Though many of the DCF inputs above can change often, comparable company multiples are typically the only inputs that change materially over a short period of time  As a result, though WACC is a critical driver of implied DCF valuation, it is the terminal multiple input (not the WACC) that is generally the cause of large changes in implied DCF valuation over short periods of time 3
