Renaissance Learning, Inc. Announces Fourth Quarter Results

WISCONSIN RAPIDS, Wis., — January 25, 2006 — Renaissance Learning^®, Inc., (Nasdaq: RLRN), a leading provider of computerized assessment and progress monitoring tools for pre-K-12 schools and districts, today announced financial results for the quarter and year ended December 31, 2005.  Revenues for the fourth quarter of 2005 were $29.0 million, an increase of 14.8% from fourth quarter 2004 revenues of $25.3 million.  Net income, was $6.0 million compared to net income of $5.2 million for the fourth quarter of 2004, an increase of 15.8%.  Earnings per share for the quarter were $0.20, compared to $0.17 per share earned in the prior year. The current quarter results included a pre-tax gain of $1.8 million on the sale of an office building and a decrease in income tax expense of approximately $0.8 million primarily from the favorable resolution of certain state and federal tax positions. Also last year fourth quarter results do not include the revenue and earnings from Alpha Smart, which was merged with Renaissance Learning in June.

Revenues for the twelve-month period ended December 31, 2005 were $116.3 million, up 4.1% from the 2004 revenues of $111.7 million.  Net income for 2005 was $24.8 million, or $.80 per share, compared to net income of $22.7 million, or $.73 per share for 2004.

“Our revenues for our core business, pre-AlphaSmart, while still down slightly for the quarter, continued to show improving trends for the fifth quarter in a row,” commented John R. Hickey, president and chief executive officer of Renaissance Learning, Inc.  “Although AlphaSmart^™ product sales were weaker in the quarter compared to last year, our investment in R & D continues and we remain confident about being able to generate revenue and profit growth from the combined Renaissance Learning and AlphaSmart product line.”

“This quarter is exceptional in that we began shipping two new products, ReadNow with Power Up, our new middle school reading intervention program and the Renaissance Classroom Response System,” said Hickey,  “and there is high interest in both products.”

“With regard to Read Now with PowerUp! it is evident that there is a strong need for an affordable, research-based reading intervention solution that targets struggling readers in grades 5-9,” said Hickey. “This solution provides educators a complete package of progress monitoring technology, reading skills, instructional materials and engaging fiction and nonfiction paperback books to help students needing remediation.”

The Classroom Response System (CRS) incorporates leading radio frequency (RF) technology and easy-to-use interactive software with a remote wireless handheld devise.

“The Renaissance Classroom Response System has resulted in substantial interest from educators, higher than any we have seen in recent years,” said Hickey. “Grading student assignments, and creating tests and quizzes is very time consuming work for teachers, but now with CRS teachers can create test questions in a fraction of the time it takes using traditional methods.”

Excluding AlphaSmart products, Renaissance Learning added about 300 new customer schools in the U.S. and Canada during the quarter, bringing total North American schools that have adopted Company products to more than 69,000.  Of these, more than 65,000 have adopted the Company’s reading products and more than 27,000 have adopted the Company’s math products.
