BUSINESS AT THE END OF JUNE 2025: -1.1%

In the first half of the year, the decline in activity was -1.1%: +3.8% in France, -3.5% outside France. At constant scope and exchange rates, the decline was -5.6% (-4.3% in France and -6.2% outside France). Activity was penalized by 1.5 fewer working days compared to the first half of 2024. At constant working days, the decline would have been -4.7%.

In the second quarter, ALTEN achieved a turnover of €1,022.1 million, down 1.8% compared to the second quarter of 2024. On a constant basis, the organic decline was 5.7% (-4.8% in France and -6.1% outside France).

The Group's activity was penalized by the sharp decline in the Automotive sector (-15%). Excluding Automotive, the Group's decline was -3.4% (or -2.5% at constant working days).

All sectors of activity are in decline except for Defense/Security/Naval, Energy, and Rail.

The second quarter did not mark a trend reversal. Except for Southern Europe, which continues to grow, and Eastern Europe, which is stable, other geographical areas are in more or less significant decline.

OUTLOOK FOR 2025:

As anticipated, the activity in the second quarter of 2025 continued in the same vein as the first quarter. The economic environment remains uncertain, and visibility is still limited for the second half of the year.

Assuming unchanged economic conditions, ALTEN anticipates an organic decline of between 5.2% and 5.5% for the entire year of 2025.

Consequently, the operating margin for 2025 will be impacted by an unfavorable calendar and a lower SG&A cost coverage ratio compared to last year, despite the cost reductions undertaken. It is expected to be around 8% and 8.1% of revenue, with marked seasonality between the first and second halves of the year due to the calendar (a difference of 4 working days between the first and second halves).

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.
