Non-GAAP Financial Measures

This press release contains the following non-GAAP financial measures: adjusted operating expenses and adjusted EBITDA. Adjusted operating expenses excludes depreciation, amortization and accretion, goodwill and restructuring costs, and includes capitalized software development costs. Adjusted EBITDA represents net income/(loss) before interest income/expense, income tax expense/benefit, depreciation, amortization and accretion expense restructuring costs, and stock-based compensation expense and includes capitalized software development costs.

We believe that these non-GAAP financial measures provide useful information to management and investors regarding certain financial and business trends relating to Spok's financial condition and results of operations. We use these non-GAAP measures for financial, operational, and budgetary decision-making purposes, to understand and evaluate our core operating performance and trends, and to generate future operating plans. We believe that these non-GAAP financial measures permit us to more thoroughly analyze key financial metrics used to make operational decisions and allow us to assess our core operating results. We believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing our financial measures with other software companies who present similar non-GAAP financial measures. We adjust for certain items because we do not regard these costs as reflective of normal costs related to the ongoing operation of the business in the ordinary course. In general, these items possess one or more of the following characteristics: non-cash expenses, factors outside of our control, items that are non-operational in nature, and unusual items not expected to occur in the normal course of business.

We do not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal of these non-GAAP financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded in the Company's financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgment by management about which expenses and income are excluded or included in determining these non-GAAP financial measures. In order to compensate for these limitations, management presents non-GAAP financial measures in connection with GAAP results. We urge investors to review the reconciliation of our non-GAAP financial measures to the comparable GAAP financial measures, which are included in this press release, and not to rely on any single financial measure to evaluate our business.
