BUSINESS UP +9.1% IN THE QUARTER ENDED MARCH 31ST 2018

Business grows by 9.1% in Q1 2018 reaching 7.7% in France and 10.4% abroad; on a like‐for‐like basis and constant exchange rate, it increased by 8.5% (7.7% in France and 9.3% outside France). Restated for the number of business days (‐1 working day in Q1) and at constant exchange rate, growth would have reached 10.2% (9.4% in France and 11% abroad).

France sustains a robust growth rate in consistency with the increase recorded at the end of 2017. Business abroad also grows sharply and more specifically in North America, Spain and Benelux.

All business sectors are growing: Aerospace, Defence & Security, Life Sciences and Rail/Naval experience sharp growth.

EXTERNAL GROWTH: 3 ACQUISITIONS OUTSIDE FRANCE

ALTEN is consolidating its positions abroad and has carried out 3 acquisitions since the beginning of 2018:

• ‐ 2 companies in Austria and Spain (annual revenue: €14M, 245 consultants)
• ‐ 1 company in China (annual revenue: €7M, 160 consultants)

OUTLOOK FOR 2018:

The beginning of 2018 shows that our activity remains well oriented in almost all geographical areas and business sectors. ALTEN confirmed its main reference listings and acquired new ones mostly abroad. Assuming similar economic conditions, ALTEN should achieve a satisfactory positive organic growth again.

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 comprehensive 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 excluding acquisitions, revenue of the period and for transfers, revenue of the previous period, 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.
