Ingénierie et Conseil en Technologies Sensitivity: C1-Internal APPENDIX TO PRESS RELEASE: Definition of alternative performance measures and reconciliation with IFRS standards The ALTEN Group uses alternative performance measures especially selected to follow up on its operational activities. The Group has chosen these measures as they supply additional information allowing the users of periodic financial information to have a c omprehensive understanding of the Group’s performance. Such alternative performance measures are complementary to IFRS standards. Revenue growth on a like-for-like basis (i.e. organic growth) Growth on a like -for-like basis (and constant exchange rate) is calculated excluding the effects of exchange rate variations and the variations of the consolidation scope on a chosen period. Exchange rate impacts are measured by converting the revenue of the period with the average exchange rate from the previous period. Scope variation impacts are measured by excluding revenue of the period from acquisitions and revenue of the previous period from disposals in order to create a scope which is identical to the previous period. This alternative measure enables to identify the real performance of the Group in terms of activity on the chosen period.
