Renaissance Learning, Inc. Announces Second Quarter, 2011 Results

WISCONSIN RAPIDS, WI — July 21,  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 June 30, 2011. Revenues for the second quarter of 2011 were $35.7 million, an increase of 15.0% from second quarter 2010 revenues of $31.0 million. Net income was $5.3 million, or $0.18 per share, 23.4 % higher than second quarter 2010 net income of $4.3 million, or $0.15 per share.

Revenues for the six-month period ended June 30, 2011 were $69.2 million, up 9.4% from revenues of $63.3 million for the first half of 2010.  Net income was $10.8 million for the first six months of 2011, up 7.1% from the prior year’s net income of $10.1 million.  Earnings per share for the six months ending June 30, 2011 were $0.37 compared to $0.34 for the same period in 2010.   Net income in 2010 included a tax benefit resulting from a tax audit settlement of $1.1 million, or $0.04 per share. Excluding the tax benefit in last year’s results, year over year net income per share for the six month period increased by $0.07.   

“We are pleased to have achieved continued growth and solid financial results for the second quarter, especially considering the challenging funding environment,” commented Glenn R. James, Chief Executive Officer.  “Orders for the quarter were 18% higher than the prior year, offsetting a similar percentage decline in the first quarter and reflecting the continued seasonal shift of orders to Q2 and Q3.

“The strong order performance was highlighted by a solid start to the launch of the STAR Enterprise product line,” continued James.  “Orders also were boosted by a large NEO order and by a number of customers renewing their subscriptions early.

“Despite the strength of our second quarter orders, we remain cautious in the near term as states are continuing to cut or delay education funding, and the third quarter is our largest order period,” added James.  “However, in spite of the school budget challenges, we believe we are well positioned strategically and financially to achieve solid growth over the longer term.”
