EVA stands for

In corporate finance, as part of fundamental analysis, economic value added is an estimate of a firm's economic profit, or the value created in excess of the required return of the company's shareholders.

EVA is the net profit less the capital charge ($) for raising the firm's capital. The idea is that value is created when the return on the firm's economic capital employed exceeds the cost of that capital.

This amount can be determined by making adjustments to GAAP accounting. There are potentially over 160 adjustments but in practice only several key ones are made, depending on the company and its industry.
