There are three main methods for valuing a company: asset valuation, market multiples, and discounted cash flow. Asset valuation values the company based on its assets as shown on the balance sheet, either at book value or adjusted market value. Market multiples compare ratios such as price-to-book or enterprise value to EBITDA to similar public companies. Discounted cash flow estimates future dividends or cash flows from the company and discounts them to calculate a net present value.
