ENGLEWOOD, Colorado — Evolving Systems, Inc. (NASDAQ-EVOL), a leading provider of software solutions and services to the wireless, wireline and IP carrier market, today reported solid profitability on growing revenue for its fourth quarter and full year ended December 31, 2007.

“Q4 represented a strong finish to a good year for Evolving Systems,” said Thad Dupper, president and CEO.  “In 2007 we delivered solid revenue and earnings growth while strengthening our balance sheet.  We also made excellent progress on the new business front, opening 10 new accounts in 2007 versus three in 2006 — a fact that underscores our success in the emerging markets of Central and Latin America, Asia and Africa.  While we expect to achieve steady growth in traditional markets, we continue to believe that emerging markets offer the best potential for significant growth.  We enter 2008 with an impressive order backlog, a growing portfolio of software solutions and a proven sales organization that is well-placed to pursue global opportunities.”

Fourth Quarter Results

Evolving Systems reported $9.1 million in revenue in the fourth quarter, up 3% from revenue of $8.8 million in the fourth quarter a year ago.  It was the Company’s fourth straight quarter of increased year-over-year revenue.  Management attributed the steady revenue growth to a combination of new customer engagements, additional revenue from established customers, and success in opening new, emerging markets.  License fees and services revenue grew by 11% to $4.5 million from $4.0 million, more than offsetting a 4% decline in customer support revenue, which was $4.6 million versus $4.8 million in the same quarter last year.  Revenue mix in the fourth quarter included $4.7 million in Service Activation, $3.2 million in Numbering Solutions and $1.2 million in Mediation.

Net income in the fourth quarter was $284,000, or $0.01 per basic and diluted share, versus net income of $1.0 million, or $0.05 per basic and diluted share, in the same quarter last year.  The decline in year-over-year net income was attributable to higher costs in the 2007 fourth quarter to support expanding operations and new product development.  Earnings before interest, taxes, depreciation, amortization, impairment, stock compensation and gain/loss on foreign exchange transactions (“adjusted EBITDA”) for the fourth quarter were $1.2 million versus $2.0 million in the same quarter last year.

Total costs of revenue and operating expenses in the fourth quarter increased to $8.6 million from $7.7 million in the same quarter last year, reflecting the incremental costs of managing increased revenue.  Sales and marketing expense increased 14% due to increased costs associated with pursuing new geographic markets.  General and administrative expense increased 11% due to higher professional fees.  And product development expense increased 19% due to ongoing enhancements to the Company’s Tertio™ Activation suite.

Income from operations in the fourth quarter was $500,000 as compared with $1.1 million in the same quarter last year.  It was the Company’s sixth consecutive quarter of positive operating income.

Bookings and Backlog Highlights

The Company achieved its strongest license and services bookings quarter since the 2004 acquisition of Tertio Telecoms, writing new business with six new carrier customers.  License and services bookings totaled $6.4 million, up from $4.6 million in the same quarter last year.  Customer support bookings increased to $10.2 million from $5.8 million, benefiting from a change in the timing of a large renewal.  Total new order bookings in the fourth quarter totaled $16.6 million.  Bookings consisted of $7.8 million in Activation, $6.5 million in Numbering Solutions, and $2.3 million in Mediation.

Full year 2007 bookings were $42.0 million versus $34.2 million in 2006.  The mix included $19.6 million in license fees and services orders, up 16% over 2006, and $22.4 million in customer support, up 28% over 2006.  By product mix, bookings included $22.0 million in Activation, $14.2 million in Numbering Solutions and $5.8 million in Mediation.

The Company defines bookings as new, non-cancelable orders that are expected to be recognized as revenue during the following 12 months.

Backlog at December 31, 2007, was $19.7 million, up 43% from a backlog of $13.8 million at year-end 2006. The mix in backlog included $6.5 million in license fees and services and $13.2 million in customer support.

Balance Sheet Highlights

Evolving Systems generated $4.8 million in cash from operations in 2007, up 42% from $3.4 million in 2006.  Cash and cash equivalents increased 43% over the same period

to $7.3 million from $5.1 million. Working capital at 2007 year-end was up 74% to $1.4 million from $0.8 million a year ago.  During 2007 holders of the Company’s Series B Convertible Preferred Stock converted a substantial number of preferred shares to common stock, reducing the preferred stock balance from $11.3 million at December 31, 2006 to $5.6 million at December 31, 2007.  Subsequently, during the first quarter of 2008, additional conversions were made, further reducing the preferred stock balance to $0.2 million.  Also in the first quarter of 2008, Evolving Systems completed a $10.0 million debt refinancing that lowered the Company’s average cash interest rate and improved financial flexibility.  The financing, which carries more favorable covenants than its predecessor, will lower the Company’s 2008 principal amortization by approximately $200,000 and will generate interest savings of approximately $200,000 in 2008 and more than $250,000 in 2009.

2007 Full Year Results

The Company reported net income of $598,000, or $0.03 per basic and diluted share, in 2007 as compared with a net loss of $16.8 million, or $0.88 per basic and diluted share, in 2006.  The 2006 net loss included a $15.0 million impairment charge net of income tax benefit.  Earnings before interest, taxes, depreciation, amortization, impairment, stock compensation and gain/loss on foreign exchange transactions (“adjusted EBITDA”) for 2007 increased 26% to $5.6 million from $4.5 million in 2006.

Revenue in 2007 increased to $36.0 million, up 6% over $33.8 million a year ago.  License fees and services revenue increased 13% to $17.9 million from $15.9 million, while customer support revenue increased 1% to $18.1 million from $17.9 million in 2006.  Revenue mix included $19.6 million in Activation, $11.9 million in Numbering Solutions and $4.5 million in Mediation.

Total costs of revenue and operating expenses in 2007 improved to $33.5 million from $50.4 million in 2006.  The significant improvement is primarily the result of the 2006 impairment charge of $16.5 million, which also produced a lower amortization expense run rate.  Other areas of decreased expense in 2007 included sales and marketing, which incurred lower average headcount, and product development due to reduced numbering solutions development costs.  The Company experienced year over year increases in costs of revenue to support revenue growth and in general and administrative expense, which grew due to higher professional fees and incentive compensation resulting from improved year over year financial results.

Operating income in 2007 was $2.4 million compared with an operating loss of $16.6 million, including the $16.5 million impairment, in 2006.

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 information in the form of adjusted EBITDA (earnings before interest, taxes, depreciation, amortization, impairment, stock compensation and gain/loss on foreign exchange transaction.)  Management believes adjusted EBITDA is useful to investors and lenders in evaluating the overall financial health of the Company in that it allows for greater transparency of additional financial data routinely used by management to evaluate performance.  Adjusted EBITDA relates to a covenant contained in the Company’s loan agreements and therefore can be useful for lenders as an indicator of earnings available to service debt.  Readers of this adjusted EBITDA information are reminded that adjusted EBITDA is not a recognized term under GAAP and does not purport to be an alternative to income (loss) from operations, an indicator of cash flow from operations or a measure of liquidity.  Not all companies calculate adjusted EBITDA identically, so this presentation may not be comparable to similar presentations of other companies.
