Renaissance Learning, Inc. Announces First Quarter, 2009 Results

WISCONSIN RAPIDS, WI — April 16, 2009 — 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, 2009. Revenues for the first quarter of 2009 were $28.9 million, a decrease of 1.8% from first quarter 2008 revenues of $29.4 million. Net income was $3.9 million, or $.13 per share, compared to net income of $2.6 million, or $.09 per share, for the first quarter last year.

“We are pleased to report solid financial results for the first quarter, especially given the serious recessionary environment,” commented Terrance D. Paul, Chief Executive Officer.  “Revenue held up at close to last year’s level due to the recognition of deferred revenue from the strong orders in last year’s second and third quarters, and we achieved higher earnings due to improved gross margins and lower operating costs.  On the negative side, orders declined by 16% compared to last year’s first quarter.  Schools reduced their purchases because of shortfalls in state revenues and also because they are waiting to determine what they will receive from the government stimulus programs, particularly the American Recovery and Reinvestment Act (ARRA).

“ARRA includes significant funding for education, targeting initiatives which many of our products support. In the last 30 days we have seen an increase in quote activity, which suggests schools are preparing to deploy some of their stimulus funds,” added Paul.  “The near term benefit of the stimulus funds, combined with our long track record of providing products that accelerate learning, leads us to believe we are well positioned to achieve improved growth in the future.”

Renaissance Learning added approximately 500 new customer schools during the quarter, bringing total schools worldwide that are actively using the Company’s products to over 74,000. Of these, more than 27,000 are actively using at least one product running on the Renaissance Place platform.
