ENGLEWOOD, Colorado — Evolving Systems, Inc. (NasdaqCM-EVOLD), a leading provider of software solutions and services to the wireless, wireline and cable markets, today reported increased profitability and strong overall results for its second quarter and six month period ended June 30, 2009.

“We continue to experience solid demand for our solutions, highlighted by growing interest in our new product offerings in emerging markets, where we have been aggressively targeting carriers for the past few years,” said Thad Dupper, president and CEO of Evolving Systems.  “We experienced good growth in constant currency revenue, operating income, net income and adjusted EBITDA.  We’re particularly pleased with fully diluted EPS of $0.11 in the second quarter and $0.21 for the six-month period, after reflecting the effect of our one-for-two reverse stock split.

“We recorded two more sales of our new Dynamic SIM Allocation™ (DSA) solution in the second quarter, bringing the total number of DSA sales year to date to four — three with customers in emerging markets and one with a customer in Europe,” Dupper added.  “Our newest product offerings — DSA and our international NumeriTrack® (iNT)

solution — comprised 21% of revenue and 43% of new orders during the second quarter — an important indicator that our focus on new products and emerging markets is paying off.”

Second Quarter Results

Second quarter net income rose 42% to $1.1 million, or $0.11 per basic and diluted share, from $775,000, or $0.08 per basic and diluted share, in the second quarter of 2008.  It was the Company’s most profitable second quarter since 2003 and fifth consecutive profitable quarter overall.  Non-GAAP adjusted EBITDA for the second quarter was $2.4 million, up 21% from $2.0 million in the same quarter last year.

Due to the stronger U.S. dollar in the second quarter of 2009 compared with the second quarter of 2008, reported revenue in the second quarter was essentially flat at $9.6 million.  However, when adjusted for the change in foreign currency exchange rates, second quarter revenue increased 8% year over year due to growing demand for the Company’s DSA and iNT solutions in emerging markets.  Reported license fees and services revenue as well as customer support revenue totals were nearly flat at approximately $5.4 million and $4.3 million, respectively, for the comparative second quarters.  Second quarter revenue mix included $5.6 million in Service Activation, $3.4 million in Numbering Solutions and $0.6 million in Mediation.

Total costs of revenue and operating expenses in the second quarter declined 8% to $7.8 million in 2009 from $8.5 million in 2008, reflecting the positive effects of foreign exchange transactions principally involving the British Pound Sterling.  Adjusted for currency changes, total expenses were up approximately 5%.  The increase in second quarter constant currency expenses was due to higher costs of revenue to support the constant currency revenue growth, increased selling costs to cover the emerging markets, and higher professional fees.

Second quarter income from operations was up 63% to $1.8 million from $1.1 million in the comparable quarter last year.  It was the Company’s 12th consecutive quarter of positive operating income and the second highest total in that category since 2003.

6-Month Results

The Company reported a 290% increase in net income to $2.1 million, or $0.21 per basic and diluted share, through six months as compared with net income of $531,000, or $0.05 per basic and diluted share, in the same period a year ago.  Adjusted EBITDA for the six-month period was $4.3 million, a 47% increase over the total of $2.9 million a year ago.

Again, due to the comparatively stronger U.S. dollar in 2009, reported revenue through the first six months of 2009 declined slightly to $18.5 million from $18.8 million in the same period a year ago.  On a constant currency basis, however, revenue increased 8% based on solid growth in demand for new products.  License fees and services revenue declined slightly — to $10.1 million from $10.2 million — while customer support revenue was $8.4 million versus $8.6 million in the year ago period.  Revenue mix

included $10.5 million in Activation, $6.8 million in Numbering Solutions and $1.2 million in Mediation.

Total costs of revenue and operating expenses through the first six months of 2009 benefitted from the effects of foreign currency exchange transactions, declining by nearly 13% to $15.3 million from $17.6 million in the comparable six-month period last year.  On a constant currency basis, total costs of revenue and operating expenses increased approximately 2%.

Operating income through six months of 2009 grew 161% to $3.2 million from $1.2 million in the same period of 2008.

Bookings and Backlog Highlights

The Company booked $10.5 million in new orders in the second quarter, a 26% increase over bookings of $8.3 million in the second quarter last year and a 67% increase over bookings of $6.3 million in the first quarter of this year.  Second quarter bookings included $6.1 million in license fees and services and $4.4 million in customer support, representing year over year increases of 15% and 45%, respectively.  Bookings by product category in the second quarter included $6.9 million in Activation, $2.9 million in Numbering Solutions, and $0.6 million in Mediation.

DSA and iNT solutions combined to represent 60% of license fees and services bookings in the second quarter, with DSA contributing 52% and iNT contributing 8%.  As a percentage of total bookings, DSA represented 37% with iNT at 6% for a combined 43% of total bookings.

New orders for the first six months of 2009 increased to $16.7 million from $16.6 million in the same period last year.  Year-to-date new orders were impacted by the acceleration in the first quarter of a large, recurring 2009 license and services order into the fourth quarter of 2008.  License and services orders were flat at $10.8 million for the comparative six-month periods while support orders for the same periods increased to $6.0 million from $5.8 million.  By product category, six-month bookings included $11.0 million in Activation, $4.9 million in Numbering Solutions and $.8 million in Mediation.

Orders for DSA solutions represented 49% of license fees and services bookings through six months while iNT orders came in at 18%, bringing the combined DSA and iNT orders to 67% of license fees and services bookings in the first half of 2009.  License fees and services orders for DSA and iNT solutions in the first half increased a combined 258% over the first half of 2008.  As a percent of total new orders, DSA and iNT contributed 36% and 12%, respectively, for a total of 48% of total bookings year to date.  Emerging markets generated 81% of first half license and services orders.

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

Backlog at June 30, 2009, was $19.3 million, up 10% over $17.6 million.  The license fees and services backlog, a leading indicator, increased 35% to $9.6 million from $7.1 million, more than offsetting an 8% decline in customer support backlog.

Balance Sheet Highlights

The Company made a $1.0 million prepayment on its subordinated debt obligations in the second quarter, raising to $3.0 million the total sub-debt prepayments made year to date.  When appropriate, the Company expects to continue accelerating its debt payments in order to enhance earnings and strengthen its balance sheet.  The Company’s cash and cash equivalents balance at June 30, 2009, was $5.0 million.

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.
