Appendix

Non-GAAP Financial Measures Adjusted EBITDA is a non-GAAP (Generally Accepted Accounting Principles) financial measure, to monitor the financial performance of operations. This measurement, together with GAAP measures such as revenue and loss from operations, assists management in its decision-making processes relating to the operation of the business. Adjusted EBITDA is defined as net income (loss) from operations before interest, taxes, depreciation and amortization, impairment and restructuring charges, stock-based compensation, gain on early extinguishment of debt, debt exchange expenses and other income (expense). Adjusted EBITDA is not a substitute for operating income, net income (loss), or cash flow used in operating activities as determined in accordance with GAAP, as a measure of performance or liquidity. In addition, the presentation of Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies. This non-GAAP financial measure should be viewed in addition to, and not as an alternative for, the reported financial results as determined in accordance with GAAP. Other companies in the industry may calculate Adjusted EBITDA differently than FiberTower. Adjusted EBITDA is not a measure of performance under GAAP and should not be considered as a substitute for net income (loss) prepared in accordance with GAAP. Adjusted EBITDA has significant limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of the results as reported under GAAP.
