These risks and other factors you should consider include, but are not limited to, the ability to successfully attract and retain a broad customer base for current and future products, changes in customer demands or industry standards, success of ongoing product development, maintaining acceptable margins, the ability to control costs, K–12 enrollment and demographic trends, the level of educational funding, the impact of federal, state, and local regulatory requirements on the business of the company, the loss of key personnel, the impact of competition, the uncertainty of general economic conditions and financial market performance, and those other risks and uncertainties listed under the heading “RISK FACTORS” in Cambium Learning Group, Inc.’s Form 10-K and other reports filed with the Securities and Exchange Commission.

These statements are only predictions. Actual events or results may differ materially. Cambium Learning Group, Inc., does not assume or undertake any obligation to update the information contained in this press release, and expressly disclaims any obligation to do so, whether as a result of new information, future events, or otherwise. Non-GAAP Financial Measures Bookings, EBITDA, Adjusted EBITDA, and Cash Income are not prepared in accordance with GAAP and may be different from similarly named, 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 these non-GAAP measures 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 Cash Income remove significant purchase accounting, non-operational, or certain non-cash items from earnings. The Company uses Bookings, Adjusted EBITDA, and Cash Income to monitor and evaluate the operating performance of the Company and as the basis to set and measure progress toward 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. The Company’s presentation of Bookings, EBITDA, Adjusted EBITDA, and Cash Income should not be construed as an indication that our future results will be unaffected by unusual, non-operational, or non-cash items.
