Renaissance Learning, Inc. Announces Second Quarter, 2010 Results

WISCONSIN RAPIDS, WI — July 19, 2010 — 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 June 30, 2010. Revenues for the second quarter of 2010 were $31.0 million, an increase of 9.1% from second quarter 2009 revenues of $28.5 million. Net income was $4.3 million, or $0.15 per share, an increase of 4.2% from second quarter 2009 income of $4.1 million or $0.14 per share for the second quarter last year.

Revenues for the six-month period ended June 30, 2010 were $63.3 million, up 10.4% from 2009 revenues of $57.3 million. Net income was $10.1 million for the six-month period ended June 30, 2010, up 25.5% from the prior year’s net income of $8.0 million. Earnings per share for the first half of 2010 were $.34, compared to $.28, in the first six months of 2009.

“Second quarter results continue to reflect the underlying strength of our business,” commented Terrance D. Paul, Chairman of the Board.  “Orders increased 11%, reported revenue was up 9% and our cash flow was strong.  We are satisfied with the earnings growth despite being lower than the past several quarters as it was affected by our investments in expanded sales resources and by commissions paid on the order increases which are not yet fully recorded in revenue.”

“Despite state budgets remaining weak which will likely affect education funding for at least the next school year, we remain optimistic about our growth prospects,” added Glenn R. James, Chief Executive Officer.  “All product lines are performing well and we intend to build on that with our planned enhancements to the STAR^TM assessment products, with our focus on urban districts, and through other initiatives and strategies.  We believe we are well positioned strategically and financially to handle any short-term funding issues and to achieve solid long term growth.”
