Renaissance Learning Announces First Quarter Financial Results

WISCONSIN RAPIDS, Wis., — April 20, 2005 — Renaissance Learning, Inc., (Nasdaq: RLRN), a leading provider of learning information systems and school improvement programs for pre-K-12 schools, today announced financial results for the three month period ending March 31, 2005. Net income, including income from discontinued operations of Generation21 of $0.6 million or $.02 per share, was $6.5 million compared to $5.9 million for the first quarter 2004, an increase of 8.8%.  Diluted net income per share for the quarter was $0.21, compared to $0.19 per share for first quarter 2004.  Revenues, which exclude the impact of discontinued operations, were $27.6 million, a decrease of 11.0% from first quarter 2004 revenues of $31.0 million.

“A more pronounced seasonality with Renaissance Place, as well as the challenging market conditions caused orders to lag last year’s levels,” noted John R. Hickey, president and chief executive officer of Renaissance Learning. “However, the percentage decline in both orders and revenue was improved over the fourth quarter and our strategic initiatives appear ready to bear fruit.   We completed the divestiture of our Generation21 subsidiary in the first quarter and we expect the merger with AlphaSmart to close in the second quarter as planned.  Our summer reading program, which currently includes about 300 communities nationwide, and our English In a Flash software are showing good initial momentum. The StandardsMaster enhancements are also underway and, with over 4,900 schools who now have one or more of our products on the Renaissance Place platform, we are now expecting that number to grow to 10,000 installations by the end of the year.”  

Renaissance Learning held its sixth annual National Renaissance Conference in March.  About 3,500 educators attended the event held in San Antonio, Texas, which was up from the 3,000 attendees at last year’s conference.  Renaissance Learning added about 400 new customer schools in the U.S. and Canada during the quarter, bringing total North American schools that have adopted Company products to over 67,000.  Of these, over 64,000 use the Company’s reading products and over 25,000 use math.
