Q1. Walk me through a Discounted Cash Flow (DCF) model. What are its key assumptions and sensitivities?
Why you'll be asked this: This question assesses your fundamental understanding of valuation methodologies, your ability to articulate complex financial concepts, and your awareness of the drivers and limitations of a DCF model. Interviewers want to see if you can go beyond just listing steps to explaining the 'why' behind each component.
Start by defining a DCF as a valuation method that projects a company's future free cash flows and discounts them back to the present using a discount rate (WACC). Detail the steps: 1) Project free cash flow for 5-10 years, 2) Calculate terminal value (Gordon Growth or Exit Multiple), 3) Discount all cash flows (projected and terminal) using WACC, 4) Sum discounted values to get enterprise value, 5) Adjust for net debt and preferred stock to get equity value. Discuss key assumptions like revenue growth, margins, CAPEX, working capital, WACC components (cost of equity, cost of debt, tax rate), and terminal growth rate/exit multiple. Highlight sensitivities to WACC and terminal value.
- Inability to explain WACC or its components.
- Not mentioning terminal value calculation methods.
- Failing to identify key assumptions or sensitivities.
- Confusing free cash flow to firm (FCFF) with free cash flow to equity (FCFE) without clarification.
- How would you value a company with negative free cash flow?
- What are the advantages and disadvantages of using a DCF versus comparable company analysis?
- How do you determine an appropriate discount rate (WACC) for a private company?
