WISCONSIN RAPIDS, WI — January 27, 2011 — Renaissance Learning^™, Inc. (Nasdaq: RLRN), a leading provider of technology-based school improvement and student assessment programs for K12 schools, today announced financial results for the quarter ended December 31, 2010. Revenues for the fourth quarter of 2010 were $34.2 million, an increase of 5.5% from fourth quarter 2009 revenues of $32.4 million. Net income was $7.6 million, or $0.26 per share, an increase of 13.4 % from fourth quarter 2009 income of $6.7 million, or $0.23 per share.

Revenues for the twelve-month period ended December 31, 2010 were $130.1 million, up 7.1% from 2009 revenues of $121.5 million. Net income was $23.9 million for the twelve-month period ended December 31, 2010, up 19.9% from the prior year’s net income of $19.9 million.

“We are pleased to report solid financial results in the midst of a difficult education funding environment,” commented Glenn R. James, Chief Executive Officer.   “Revenue and earnings both achieved steady growth compared to fourth quarter 2009, operating margins remained strong at nearly 33%, and cash flow was healthy.  However, orders declined by 11% in the quarter, reflecting both a continuation of the seasonal shift in our order pattern and the economic environment.

“We expect school funding to remain challenging for at least the next school year,” continued James, “On the other hand, we believe the long term potential for our business is outstanding, and that we have the right products at the right time. Therefore, in the face of the current difficult environment, we are continuing to make investments in our products and resources, which we believe will improve our growth trajectory in the future.”
