Appendix Discussion of Non-GAAP Measures: EBITDA, Adjusted EBITDA and Adjusted EBITDA per the Credit Agreement – The Company’s management believes that EBITDA is a useful supplement and meaningful indicator of earnings performance to be used by its investors, financial analysts and others to analyze the Company’s financial performance and results of operations over time. Management believes that the inclusion of supplementary adjustments to EBITDA applied in presenting Adjusted EBITDA is appropriate to provide additional information to investors about one of the principal internal measures of performance used by the Company. Management uses the Adjusted EBITDA measure to evaluate the performance of the Company and to evaluate results relative to incentive compensation targets. Adjusted EBITDA per the Credit Agreement adds the pro forma impact of recent acquisitions and the pro forma cost savings per the credit agreement to Adjusted EBITDA. This measure is used by the Company’s creditors in assessing debt covenant compliance and management believes its inclusion is appropriate to provide additional information to investors about certain covenants required pursuant to the Company’s senior secured credit facility and notes. The most directly comparable financial performance measure calculated and presented in accordance with GAAP is net income (loss). A reconciliation of net income (loss) to EBITDA, Adjusted EBITDA and Adjusted EBITDA per the Credit Agreement is contained in this appendix. EBITDA, Adjusted EBITDA and Adjusted EBITDA per the Credit Agreement, as presented herein, are supplemental measures of the Company’s performance that are not required by, or presented in accordance with, generally accepted accounting principles in the United States (“GAAP”). They are not measurements of the Company’s financial performance under GAAP and should not be considered as alternatives to revenues, net income (loss) or any other performance measures derived in accordance with GAAP or as alternatives to cash flow from operating activities as measures of the Company’s liquidity. EBITDA, Adjusted EBITDA and Adjusted EBITDA per the Credit Agreement measures have limitations as analytical tools, and should not be considered in isolation, or as a substitute for analysis of the results as reported under GAAP. These measures may not be comparable to similarly titled measures reported by other companies. |
