ENGLEWOOD, Colorado — Evolving Systems, Inc. (Nasdaq: EVOL), a leading provider of activation-based solutions to telecom operators worldwide, today reported financial results for its third quarter and nine-month period ended September 30, 2013.

“We are particularly pleased with our license and services bookings, up 58% over the second quarter, as we gained momentum in our order flow,” said Thad Dupper, Chairman and CEO.  “During the third quarter we signed a DSA license upgrade which contributed to an increase in gross margin — to 74% from 69% — over last year’s third quarter.  For the comparative nine-month periods, adjusted EBITDA increased by 11% to $5.0 million from $4.6 million and cash generated from operating activities increased more than three-fold to $7.3 million from $1.6 million.  Perhaps the most significant highlight of the third quarter was in the area of new customer wins as we added two new DSA accounts and one new TSA account.   In particular, our DSA wins strengthen our position as the global leader in the growing market segment of SIM card activation.  As a result of our renewed momentum in license and services bookings, we’re pleased to report our Board of Directors has declared a fourth quarter dividend of $0.10 per share.

“Early in the fourth quarter Evolving Systems acquired Telespree Communications, which provides cloud-based service activation and mobile broadband enablement solutions to carriers in the United States,” Dupper added.  “We expect this acquisition to accelerate our introduction of a cloud-based DSA solution in addition to enhancing our solutions for the connected device and M2M markets.  Additionally, Telespree’s 11 U.S. patents further strengthen our IP portfolio, bringing to 15 our total number of issued patents.”

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.
