Non-GAAP Financial Measures

Certain non-GAAP financial measures are presented in this press release, including Adjusted EBITDA, to provide information that may assist investors in understanding the Company’s financial results and assessing its prospects for future performance. We believe these non-GAAP financial measures are important indicators of our operating performance because they exclude items that are unrelated to, and may not be indicative of, our core operating results. These non-GAAP financial measures, as we calculate them, may not necessarily be comparable to similarly titled measures of other companies and may not be appropriate measures for comparing the performance of other companies relative to the Company. These non-GAAP financial results are not intended to represent, and should not be considered to be more meaningful measures than, or alternatives to, measures of operating performance as determined in accordance with GAAP. To the extent we utilize such non-GAAP financial measures in the future, we expect to calculate them using a consistent method from period to period. A reconciliation of each of the GAAP financial measures to the most directly comparable non-GAAP financial measures has been provided under the heading “Reconciliation of GAAP versus Non-GAAP Financial Results” in the financial statement tables attached to this press release. Consistent with SEC regulations, we have not provided a reconciliation of forward-looking non-GAAP financial measures to the most directly comparable GAAP financial measures in reliance on the “unreasonable efforts” exception set forth in the applicable regulations, because there is substantial uncertainty associated with predicting any future adjustments that we may make to our GAAP financial measures in calculating our non-GAAP financial measures.
