| | - | expresses
                                         our opinion that Advanced Accelerator Applications S.A. did not maintain effective internal
                                         control over financial reporting as of December 31, 2016 because of the effect of the
                                         material weaknesses related to the controls over significant unusual transactions and
                                         calculation of significant estimates, the controls over the calculation of contingent
                                         liabilities and the controls over the preparation and review of the cash flow statement
                                         on the achievement of the objectives of the control criteria; and

                                         explanatory paragraphs that state that (i) we do not express an opinion or any other
                                         form of assurance on management' s statements referring to the remediation efforts to
                                         address the aforementioned material weaknesses in internal control over financial reporting
                                         and (ii) Advanced Accelerator Applications S.A acquired IDB during 2016, and management
                                         excluded from its assessment of the effectiveness of Advanced Accelerator Applications
                                         S.A’s internal control over financial reporting as of December 31, 2016, IDB’s
                                         internal control over financial reporting associated with total assets of €5.7 million,
                                         total revenue of €7.9 million and total net income of €0.9 million included
                                         in the consolidated financial statements of Advanced Accelerator Applications S.A as
                                         of and for the year ended December 31, 2016. Our audit of internal control over financial
                                         reporting of Advanced Accelerator Applications S.A also excluded an evaluation of the
                                         internal control over financial reporting of IDB.
