WISCONSIN RAPIDS, WI — October 19, 2009 — Renaissance Learning^™, Inc.

Revenues for the third quarter of 2009 were $31.8 million, an increase of 12.6% from third quarter 2008 revenues of $28.2 million. Net income was $5.2 million, or $.18 per share, compared to net income of $2.6 million, or $.09 per share, for the third quarter last year.

Revenues for the nine-month period ended September 30, 2009 were $89.1 million, up 4.0% from 2008 revenues of $85.6 million.

“I am pleased to report these excellent third quarter results,” commented Terrance D. Paul, Chief Executive Officer.  “Third quarter revenue is the highest quarterly revenue since 2003, earnings doubled from last year’s third quarter, and operating cash flow of $16.7 million was a new quarterly high. Orders were up 34% for the quarter.

“As good as this quarter was, future periods will likely be more challenging due to seasonal variations and to recession-related pressure on school funding, especially as stimulus dollars are used up,” continued Paul. “On the other hand, our customers understand the value of our products to accelerate learning, and with our growing customer base, exceptional product lineup, strong balance sheet and solid cash flow, we believe we are positioned to achieve solid growth in the longer term.”
