EBITDA
financial statements, the most important metric for investors is the company's income, which is calculated as the company's revenue minus all its expenses. Some companies also publish their EBITDA, which, these companies usually claim, provides a more true picture of the company's profitability than the "income" number.
Specifically, a company's "income" number is always distorted by decisions that the company made in previous years. Depreciation of capital expenditures is a particularly strong factor. For example, if a company spends $99 million in new desktop computers for all its employees, the company will often decide to depreciate the purchase over three years. This way, in the first year, when the company calculates its "income" number, it pretends that it has only spent $33 million that year on desktop computers. The company's income number paints a more rosy and optimistic picture than actually occurred that year. In each of the second and third years, the company also pretends that it has spent $33 million per year on desktop computers. Hence, the company's financial picture was probably healthier than indicated by the income number, since the $33 million had actually already been paid out.
The EBITDA number, it is claimed, does not suffer from this distortion in the second and third years, so investors can get a better idea of how profitable the company really is. Some purchases are depreciated or amortized over 20 years or more, with a negative impact on the business's "income" number long after the actual financial effects of the purchases have ceased.
Critics include Warren Buffett, who famously asked, "Does management think the tooth fairy pays for capital expenditures?" Hypothetically, a company could spend a trillion dollars on capital expenditures, and this would never show up in the next million years of the company's EBITDA reports. The "income" number is therefore a more true picture, say critics of EBITDA reporting, and if an investor wishes to examine short-term financial performance, he should examine the "operating cash flow" numbers.
The Sophisticated Investor's Perspective on EBITDA
Three fundamental issue underly the use of EBITDA vs. other measures in assessing the value of a firm.
The first is that a company's capital expenditures will typically vary from year to year. Income measures try to account for this by artificially spreading the expense of capital investments over the years in which they will be generating value for the company. EBITDA removes this effect from the income measure. A professional investor can use EBITDA to approximate the fundamental earning power of the company's operations while separately factoring in the projected capital expenditures needed to maintain those operations. This is valuable because of the time value of money. A sophisticated investor knows that a large capital expenditure is less costly if it is to be made several years into the future (because during the interim period the firm can use the cash for that expenditure to generate income in other ways). Therefore the sophisticated investor looks at a "pure" measure of ongoing earnings-generating potential and then makes an educated assessment of the timing of significant capital expenditures.
The second issue is that the value of a company's equity differs depending on its capital structure (whether and to what extent the company is financed with debt). Because EBITDA is also an earnings measure before interest and taxes (which vary with the amount of debt financing), it approximates the company's earnings potential if financed with no debt. If capital structure is the only concern (rather than timing of capital expenditures), then EBIT can be used. A professional investor that can contemplate changing the capital structure of a firm (e.g., through a leveraged buyout) first evaluates a firm's fundamental earnings potential (reflected by EBITDA or EBIT), and then determines the optimal use of debt vs. equity.
The third issue is that the owner of a firm's equity receives all of the cash flows generated by the firm after meeting all of the firm's commitments. This is the company's free cash flow. Before factoring in capital expenses, this is the company's
