Management also believes that investors regularly rely on non-GAAP financial measures, such as EBITDA and Adjusted EBITDA, to assess operating performance and that such measures may highlight trends in the Company’s business that may not otherwise be apparent when relying on financial measures calculated in accordance with GAAP.
