Renaissance Learning, Inc. Announces Third Quarter, 2008 Results

WISCONSIN RAPIDS, WI — October 16, 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 September 30, 2008.  Revenues for the third quarter of 2008 were $28.2 million, an increase of 9.3% from third quarter 2007 revenues of $25.8 million. Net income increased 88.0% for the third quarter of 2008 to $2.6 million, or $.09 per share, compared to net income of $1.4 million, or $.05 per share, for the third quarter last year.

Revenues for the nine-month period ended September 30, 2008 were $85.6 million, up 7.5% from 2007 revenues of $79.7 million. Net income was $8.5 million for the nine-month period ended September 30, 2008, up 75.3% from the prior year’s net income of $4.9 million. Earnings per share for the nine months of 2008 were $.30 compared to $.17 in the first nine months of 2007.

“Despite some challenging economic conditions, our results were positive in this seasonally important third quarter,” commented Terrance D. Paul, Chief Executive Officer. “Orders excluding laptops increased 18.3%, our largest quarterly increase since early 2002, deferred revenue increased a record $12.1 million, and our operating cash flow was a near-record $13 million.”

Laptop orders declined 2.2% in the quarter compared to third quarter last year.  “Our laptop line tends to be more discretionary than our reading and math software solutions and did not fare as well under the current economic pressures,” continued Paul. “However, we have reduced prices on laptops, passing on cost reductions achieved over the last two years, and are introducing several new features that we expect to accelerate laptop growth.”

“The success we are having reinforces our confidence in our business model,” added Paul. “Accelerated Reader Enterprise customer schools grew by over 2,000 in the quarter to over 15,000 schools having adopted the product.  Annual revenue from Accelerated Reader Enterprise schools is substantially higher after upgrading from previous versions of the product. With just 24% of our reading schools having upgraded to Enterprise, we believe we have significant growth potential. Although the economic situation is producing pressure on our business, we believe that we remain well positioned to achieve solid growth in the future.”
