The Defence & Security, Civil Aeronautics, Automotive and Railways sectors continued to grow at a satisfactory pace.

The trend observed in H2 2023 continued into Q1 2024, with a further slowdown in activity: France, Southern Europe and Asia posted satisfactory organic growth. However, Northern Europe, Eastern Europe and North America recorded negative growth.

OUTLOOK FOR 2024:

The first half of 2024 will confirm the slowdown observed since mid-2023 before a likely improvement starting from September/October 2024.

Despite an unfavourable macroeconomic environment, notably in Europe, ALTEN's organic growth should remain satisfactory at around 3% in 2024.

APPENDIX TO PRESS RELEASE:

Definition of alternative performance indicators and reconciliation with IFRS

The Alten Group uses alternative performance indicators selected specifically to track its operational activities. The Group has chosen these indicators as they offer additional information, allowing the users of periodic financial information to have a comprehensive understanding of the Group's performance. These alternative performance indicators 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.

Scope impact is measured excluding the revenue generated during the period for acquisitions, and excluding the revenue generated in the previous period for disposals and transfers, in order to ensure the new scope is identical to the previous period.

This indicator enables users to identify the group's intrinsic business performance over the reporting period.
