Non-GAAP Financial Measures

This release and the accompanying tables include a discussion of adjusted EBITDA, adjusted net income and adjusted net income per share, all of which are non-GAAP financial measures which are provided as a complement to results provided in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The term

“adjusted EBITDA” refers to a financial measure that we define as earnings before net interest, other income and expense, income taxes, depreciation and amortization, as further adjusted to exclude secondary offering costs, stock-based compensation and restructuring charges, if any. The term “adjusted net income” refers to a financial measure which we define as net income adjusted for amortization, stock-based compensation, secondary offering costs and restructuring charges, if any, as further adjusted for the related income tax impact of the adjustments. The term “adjusted net income per share” refers to a financial measure which we define as adjusted net income divided by adjusted weighted average diluted shares outstanding. These non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results. In addition, our definition of adjusted EBITDA, adjusted net income and adjusted net income per share may not be comparable to the definitions as reported by other companies. We believe adjusted EBITDA, adjusted net income and adjusted net income per share are relevant and useful information because it provides us and investors with additional measurements to compare the Company’s operating performance. These measures are part of our internal management reporting and planning process and are primary measures used by our management to evaluate the operating performance of our business, as well as potential acquisitions. The components of adjusted EBITDA include the key revenue and expense items for which our operating managers are responsible and upon which we evaluate their performance. In the case of senior management, adjusted EBITDA is used as one of the principal financial metrics in their annual incentive compensation program. Adjusted EBITDA is also used for planning purposes and in presentations to our board of directors. Adjusted net income is useful to us and investors because it presents an additional measurement of our financial performance, taking into account depreciation, which we believe is an ongoing cost of doing business, but excluding the impact of certain non-cash expenses and items not directly tied to the core operations of our business. Furthermore, we intend to provide these non-GAAP financial measures as part of our future earnings discussions and, therefore, the inclusion of these non-GAAP financial measures will provide consistency in our financial reporting. A reconciliation of these non-GAAP measures to GAAP is provided in the accompanying tables.
