ENGLEWOOD, Colorado, August 2, 2016 — Evolving Systems, Inc. (Nasdaq: EVOL), a leader in real-time activation, analytics and marketing for connected mobile devices worldwide, today reported financial results for its second quarter ended June 30, 2016.

“We have completed the integration of Sixth Sense Media and are working on multiple opportunities globally in the mobile consumer engagement and marketing space,” said Thomas Thekkethala, CEO. “The recent Nova Gaming Ventures managed services deal is an example of the global opportunities where Evolving Systems is uniquely positioned to enable service providers to engage consumers and upsell next generation services such as mobile banking, entertainment, advertising and commerce to consumers world-wide.

“Since I joined Evolving Systems 10 months ago we have been positioning ourselves as a leader in managed service solutions for mobile consumer engagement and marketing. Our new managed services offering is designed to provide a recurring revenue stream that grows over time instead of our traditional one-time license and service fee.  This will generate more predictable revenue growth with better margins over the long term, although it will mean lower free cash flow during the transition period. We have also initiated significant investments in big data and stream processing technologies to support the massive event volumes and real-time requirements of these solutions.

“Having returned over $65 million in dividends to Evolving Systems stockholders since 2010, our Board of Directors has decided to suspend our quarterly dividend in order to provide maximum financial flexibility to fund these and other growth initiatives that will create long-term shareholder value. The Board will continue to monitor our progress and make determinations on potential future dividend payments accordingly.

“We have also rolled out LEAN/Agile methodologies to accelerate our marketing services, solution development and delivery to our customers, resulting in substantially improved efficiencies. This has contributed to the adjusted EBITDA increase of 80% with 33% adjusted EBITDA margins in the second quarter. These efficiencies and new business opportunities should generate recurring revenue and position us for earnings growth over the long term.”

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.
