Adjusted EBITDA			18.8				17.5				1.3				8	%			20.3				20.2				0.1				0	%

•

The Company’s adjusted net revenues plus change in adjusted deferred revenue improved by $8.3 million in the second quarter versus the same period in 2010 and $6.3 million for the first six months versus the same period in 2010. These represent increases of 17% and 8%, respectively, for the second quarter and year-to-date. Adjusted net revenues plus change in adjusted deferred revenue is a close approximation for the Company’s internal management metric order volume.

•

Year-to-date GAAP net revenues improved by 15% to $87.9 million compared with the first six months of 2010. The improvement was primarily caused by purchase accounting adjustments, which significantly reduced 2010 net revenues by $9.7 million with the corresponding reduction in 2011 being only $0.7 million.

•

Adjusted net revenues, which exclude the impact of purchase accounting, increased by 10% in the second quarter 2011 versus the same period in 2011 and by 3% for the first six months of 2011 versus 2010.

•

While the Company experienced a year-to-date order volume increase of 8%, adjusted net revenues for the same period increased by only 3% due to continued shifts to more technology and service-based sales, which have delayed revenue recognition.

•

Adjusted net revenues by business unit for the first half of 2011 and the percentage change from the first half of 2010 were as follows:

	•		Voyager: $50.2 million, down 4%
	•		Sopris: $12.5 million, up 22%
	•		Cambium Learning Technologies: $25.8 million, up 12%

•

The first half of the year has produced particularly favorable growth for the Sopris and Cambium Learning Technologies units as investments made in 2010 and into 2011 in the areas of new products, E-commerce capabilities and expanded sales resources have provided key growth engines for the unit.

•

Over one third of the Company’s total adjusted revenue now comes from technology enabled offerings in the various business units.

•

Total GAAP costs and expenses declined considerably as onetime, merger-related costs in 2010 were not repeated in 2011. Excluding onetime costs, the Company increased overall spending by approximately $2.5 million in the first half of 2011 versus 2010. Increased spending occurred in the Cambium Learning Technologies and Sopris units in line with the growth in those units. Lower shared services costs helped offset some of the increase.

•

Overall the Company experienced a sharp improvement in GAAP net loss and EBITDA. This was partially provided by the improved top line, but significant improvement came from the non-recurrence of merger related costs from 2010. On an adjusted EBITDA basis, the Company exceeded $20 million in the first six months of 2011, which was a modest improvement over the same period for 2010.

“I am pleased with the year-to-date growth in order volume across all the business units,” says Ron Klausner, Chief Executive Officer of Cambium Learning Group. “We recognize that the new norm for our customers is a state of fiscal austerity and that sustained growth in our sales is contingent upon enabling educators to effectively and efficiently improve student outcomes.”

Business Summary

•

•

Non-GAAP Financial Measures

EBITDA, adjusted EBITDA and adjusted net revenues are not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies. Non-GAAP financial measures should not be considered a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. The Company believes that adjusted EBITDA and adjusted net revenues provide useful information to investors because they reflect the underlying performance of the ongoing operations of the Company, and provide investors with a view of the Company’s operations from management’s perspective. Adjusted EBITDA and adjusted net revenues exclude items that do not reflect the underlying performance of the combined Company by removing significant one-time or certain non-cash items. The Company uses these measures to monitor and evaluate the operating performance of the Company and as the basis to set and measure progress towards performance targets, which directly affect compensation for employees and executives. The Company generally uses these non-GAAP measures as measures of operating performance and not as measures of the Company’s liquidity.
