Forward Looking Statement In addition to historical information, this presentation may contain forward-looking statements with respect to our business, capital resources, strategy and growth reflecting the current beliefs and expectations of management made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. All forward-looking statements are subject to a number of risks, uncertainties and assumptions, and you should not rely upon forward-looking statements as predictions of future events. All forward-looking statements will be based upon current estimates and expectations about future events and financial and other trends. There is no guarantee that future results, performance or events reflected in the forward-looking statements will be achieved or occur. No person assumes responsibility for the accuracy and completeness of the forward-looking statements, and, except as required by law, no person undertakes any obligation to update any forward-looking statements for any reason after the date of this presentation. Forward-looking statements include all statements that are not historical facts and, in some cases, can be identified by terms such as "anticipates," "believes," "could,” "seeks," "estimates," "intends," "may," "plans," "potential," "predicts," "projects," "should," "will," "would" or similar expressions and the negatives of those terms. Forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. Forward-looking statements represent our management's beliefs and assumptions only as of the date of the prospectus and are only predictions that may be inaccurate. You should read the Risk Factors set forth in our prospectus and other reports filed from time to time with the Securities and Exchange Commission, which factors may cause our actual future results may be materially different from what we expect. Except as required by law, we assume no obligation to update these forward-looking statements publicly, or to update the reasons why actual results could differ materially from those or our situation may change in the future. Additionally, in an effort to provide additional information management believes is a useful indicator of operating performance for the fiscal quarter ended September 30, 2019, this presentation contains a financial measure not determined by generally accepted accounting principles (GAAP): Adjusted EBITDA net loss from operations. A reconciliation to the most directly comparable GAAP financial measure of Net Loss from Operations is available on the presentation slide entitled “Adjusted EBITDA Reconciliation.” The rationale for management’s use of non-GAAP information is included in Exhibit 99.1 to the Company’s Form 8-K furnished with the SEC on November 13, 2019.
