One of the most common points of dissension between two sides in a transaction negotiation is business valuation - How much is the company worth? The main reason for this disagreement is that there are many different ways to value a business. The most common methods for valuation are discounted cash flows, market comparable multiples, and liquidation value.
Discounted Cash Flows ("DCF")
DCF discounts a company's estimated future cash flows by its cost of capital or expected return on equity to determine the current value of the company. Most valuation analysis is done with 5-7 year projections because of the difficulty in projecting cash flows much further into the future. As a result of this short time frame, the valuation of the cash flows in the later years (otherwise referred to as the "terminal" years, or the "Terminal Value") becomes very important in determining the current value of the company. It is also the key point of contention as there are different ways to come up with a Terminal Value estimate - assume cash flow remains stable in terminal years, assume cash flows grow at a steady rate in perpetuity, assume net income remains constant in perpetuity, or use a multiple of future EBITDA. There is no right or wrong answer.
Market Comps
With large, publicly-traded companies, it is easy to look at two companies in the same industry and show that the market multiple at which they trade is relatively close to one another, all else being equal. However, this becomes increasingly difficult with privately-owned companies and smaller companies because there is not an active market for their securities. One of the most common mistakes made in valuations is using a publicly-traded company's multiple to value a small privately-owned company in the same industry. Doing so ignores the additional risk typically associated with smaller companies and the lack of liquidity associated with privately-owned companies. In an industry where the average publicly-traded company trades for 10x EBITDA, a small privately-owned company may only garner a valuation of 4x EBITDA.
Liquidation Value
This methodology seeks to answer the following question: How much would the company receive if it sold all of its assets today? While informative in a turnaround and/or re-structuring situation, this method is not very practical as sellers want some recognition for the near-term growth potential and Terminal Value of their business, thus requiring a goodwill component to be added to the Liquidation Value, creating a higher overall transaction price.
There is no "correct" valuation method to use. Each transaction is different and may require different approaches to valuation. Often the best approach is to use multiple methodologies to determine a range and then use that range as a basis for negotiation.
