Earnings are also known as profits. At the most basic level, a company’s earnings consist of what’s left over after all costs are taken out from the revenue generated. Earnings are also the basis for corporate taxes. Many corporations report EBITDA, or earnings before interest, taxes, depreciation and amortization. The most important thing to watch for when researching a company is where earnings are forecasted to move. Investors want to see that the future expectations are for the earnings to grow over time.
