Appendix to Press Release:

Definition of alternative performance measures and reconciliation with IFRS

The Alten Group uses alternative performance measures especially selected to track its operational activities. The Group has chosen these measures as they supply additional information allowing the users of periodic financial information to have a comprehensive understanding of the Group's performance. Such alternative performance measures are complementary to IFRS.

Revenue growth on a like‐for‐like basis (i.e. organic growth)

Growth on a like‐for‐like basis (constant scope and exchange rates) is calculated excluding the effects of exchange rate fluctuations and changes to the consolidation scope over the reporting period.

Exchange rate impacts are measured by converting the revenue of the period with the average exchange rate from the previous period.

Impacts of changes in scope are measured excluding revenue for the period for acquisitions, and excluding revenue for the previous period for disposals and transfers, in order to create a scope which is identical to the previous period.

This alternative measure enables users to identify the actual performance of the Group's business activities over the reporting period.
