Forward Looking Statements; Non-GAAP Financial Measures
This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Statements including words such as “believes,” “expects,” “anticipates,” “intends,” “estimates,” “plan,” “will,” “may,” “look forward,” “intend,” “guidance,” “future” or similar expressions are forward-looking statements. Because these statements reflect our current views, expectations and beliefs concerning future events, these forward-looking statements involve risks and uncertainties. Investors should note that many factors, as more fully described under the caption “Risk Factors” in our Form 10-K, Form 10-Q and Form 8-K filings with the Securities and Exchange Commission and as otherwise enumerated herein or therein, could affect our future financial results and could cause our actual results to differ materially from those expressed in forward-looking statements contained in our Annual Report on Form 10-K. The forward-looking statements in this presentation are qualified by these risk factors. These are factors that, individually or in the aggregate, could cause our actual results to differ materially from expected and historical results. We assume no obligation to publicly update any forward-looking statements, whether as a result of new information, future developments or otherwise.
This presentation may refer to non-GAAP financial measures, including adjusted diluted EPS, that are not prepared in accordance with accounting principles generally accepted in the United States and that may be different from non-GAAP financial measures used by other companies. Investors are encouraged to review Endo’s current report on Form 8-K filed with the SEC for Endo’s reasons for including those non-GAAP financial measures in this presentation. No reconciliation to GAAP amounts has been provided because the majority of the amounts excluded from the comparable GAAP amounts are not currently possible to estimate with a reasonable degree of accuracy.
