Non-GAAP Financial Measures

Evolving Systems reports its financial results in accordance with accounting principles generally accepted in the U.S. (GAAP).  In addition, the Company is providing in this news release non-GAAP financial information in the form of net income, diluted net income per share and adjusted EBITDA (earnings before interest, taxes, depreciation, amortization, impairment, stock compensation and

gain/loss on foreign exchange transactions.)  Management believes these non-GAAP financial measures are useful to investors and lenders in evaluating the overall financial health of the Company in that they allow for greater transparency of additional financial data routinely used by management to evaluate performance.  Investors and financial analysts who follow the Company use non-GAAP net income and non-GAAP diluted income per share to compare the Company against other companies.  Adjusted EBITDA can be useful for lenders as an indicator of earnings available to service debt.  Non-GAAP financial measures should not be considered in isolation from or as an alternative to the financial information prepared in accordance with GAAP.
