·                  Company positioning DSA to support impending industry transition to embedded SIMs

ENGLEWOOD, Colorado, August 4, 2015 — Evolving Systems, Inc. (Nasdaq: EVOL), a leader in activation, enablement and management of services for connected mobile devices worldwide, today reported financial results for its second quarter and six-month period ended June 30, 2015.

“We fell short of expectations in the second quarter as revenue and bookings came in below our estimates,” said Thad Dupper, Chairman and CEO. “During the quarter we observed carriers’ budgets tightening and becoming less predictable as they dealt with competition from aggressive price plans and flattening of subscriber net adds, all of which made closing contracts and forecasting more of a challenge than in past quarters. Over the years our quarterly results have fluctuated, but we are pleased that despite lower revenue this quarter, our profitability metrics and our balance sheet remain strong.

“Our long-term outlook for growth is positive, especially in the developing markets where subscriber growth is six times greater than the developed markets of North America and Europe,” Dupper added. “We have made our biggest investments in the emerging markets and, as a result, we believe we are well positioned to achieve long-term growth. We are increasing our investment in partner management and business development to accelerate the pace at which our DSA partnerships start generating revenue.”

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.
