Renaissance Learning, Inc. Announces First Quarter, 2008 Results

WISCONSIN RAPIDS, WI — April 15, 2008 — Renaissance Learning^®, Inc. (Nasdaq: RLRN), a leading provider of technology to support personalized practice, differentiated instruction, and progress monitoring in reading, math and writing for pre K-12 schools and districts, today announced financial results for the quarter ended March 31, 2008.  Revenues for the first quarter of 2008 were $29.4 million, an increase of 10.1% from first quarter 2007 revenues of $26.7 million.  Net income for the first quarter of 2008 was $2.6 million, or $.09 per share, compared to net income of $1.3 million, or $.05 per share, for the first quarter last year.  First quarter 2007 results included pre-tax restructuring costs of approximately $0.5 million, or $.01 per share.

“First quarter revenue and earnings growth is a good start to 2008,” commented Terrance D. Paul, Chief Executive Officer.  “This growth reflects both the strong Accelerated Reader and Accelerated Math Enterprise subscription orders from the second and third quarter last year, which are being recognized as revenue now, and laptop order growth of 6% this quarter compared to the same quarter last year, the second consecutive quarter of growth for the laptop product line.

“We continue to see the positive impact of our Enterprise offering, with revenue to same school AR customers increasing by over $1,200 per year and software subscription revenue growing to 40% of total software revenue in the first quarter compared to 22% last year. There is also considerable customer excitement over our recent release of the new Home Connect feature of Enterprise,” continued Paul.  “However, as we have indicated previously, Enterprise also has some near-term negative effects.  It is causing orders to shift to the second and, even more so, the third quarters as schools align their subscriptions with budget cycles.  It is also causing customers to hold off purchasing quizzes as they consider upgrading.  Thus, orders were down 10.9% for the quarter, and deferred revenue decreased by $5.0 million in the first quarter of 2008 versus a $0.5 million increase in 2007.

“We expect that the economic downturn will hurt school funding and our sales in a number of states, particularly California and Florida, and now believe that our initial order projections of 15-20% growth for the full year may be too aggressive,” added Paul.  “It is too early to predict the full year impact.  However, we continue to expect orders in the second and third quarters to be strong, and with the recent release of Home Connect, we are confident of achieving solid results in 2008.”
