Professional practice relies on three global approaches: 
income, market (comparables), and asset-based. Analysts often combine them for a full picture.
1. Income Approach: The Future Drives ValueThe 
income approach measures a business by its ability to generate future cash flows.
The most common method is 
Discounted Cash Flow (DCF).How DCF works:- Forecast free cash flows (FCF) for 5–10 years.
 - Calculate terminal value (value beyond the forecast period).
 - Discount all flows back to today using the company’s WACC.
 - Sum to obtain total enterprise value.
 
Formula:Where:
- FCFₙ – Free Cash Flow in year n (after operating expenses, taxes, capex, and working-capital changes).
 
Typical formula:
- WACC – Weighted Average Cost of Capital, the blended required return of debt and equity investors.
 - n – Year of forecast.
 - TV – Terminal Value = FCFₙ₊₁ ÷ (WACC – g), with g as long-term growth rate.
 
Pros:- Captures unique business fundamentals.
 - Provides an “intrinsic” value.
 
Cons:- Highly sensitive to assumptions and forecast quality.
 - Complex for fast-growing or volatile companies.
 
Example: When Microsoft acquired gaming giant 
Activision Blizzard in 2022, the price equaled roughly 
7.8× revenue and 
18× EBITDA, reflecting the buyers’ expectations of strong future cash flows.
2. Market (Comparables) Approach: Let the Market DecideThis method values a company by comparing it to similar public firms or recent transactions.
Key multiples:- Profit-based: P/E, EV/EBITDA, EV/EBIT
 - Revenue-based: P/S, EV/Revenue
 - Sector specifics: SaaS uses ARR multiples; retail often tracks Price-to-Book; banks focus on P/B and ROE.
 
Steps:- Identify peer companies of similar size and sector.
 - Calculate their trading or deal multiples.
 - Take the median multiple.
 - Multiply by your company’s earnings or revenue.
 
3. Asset-Based Approach: Value of What You OwnThe asset method values a business as 
assets minus liabilities.Best for:
- Capital-intensive industries
 - Real-estate-heavy holdings
 - Distressed or liquidation scenarios
 
Methods include book value, fair-market value of assets, and liquidation value.
