ACTIVITY AT END-JUNE 2026: +1.2%

In the first half, activity growth stood at +1.2%: +4.4% in France and -0.5% outside France.

At constant scope and exchange rates, growth was +1.6% (+3.3% in France and +0.8% outside France).

ALTEN returned to organic growth in the second quarter of 2026, driven by more dynamic activity than anticipated.

Activity improved across all geographies, with most delivering organic growth, including Germany. Only Benelux and the Nordics were still down by more than 5%.

Activity growth accelerated in Aerospace, Defence / Security / Naval, Rail, and, to a lesser extent, Energy. The decline slowed in the other sectors.

OPERATING MARGIN ON ACTIVITY: 8.9% OF REVENUE

Operating Profit on Activity amounted to €187.3 million, up 23% compared with June 2025.

The operating margin on activity therefore rose sharply, from 7.3% of revenue in June 2025 to 8.9% in June 2026.

It increased both in France and internationally.

Improved margins in several geographies that faced difficulties last year, productivity gains on projects, and the significant reduction in SG&A initiated several half-years ago enabled the Group’s operating margin on activity to increase sharply.

OPERATING PROFIT: 7.5% OF REVENUE

Operating profit amounted to €158.3 million, up 27% compared with the first half of 2025 (€124.7 million). It includes €12.3 million in share-based payments, €6.7 million in amortisation of acquisition-related intangible assets, €12.5 million in non-recurring costs (mainly restructuring costs and acquisition fees), and a €2.6 million disposal gain.

NET INCOME, GROUP SHARE: 5.4% OF REVENUE

After taking into account the financial result (+€3.2 million), the income tax expense (€47.7 million), and the share of profit or loss of equity-accounted companies (-€0.1 million), net income, Group share, amounted to €113.8 million, representing 5.4% of revenue, up 38% compared with June 2025.

NET CASH: €313M / GEARING: -14%

Cash flow from operations before the cost of net financial debt and tax (excluding IFRS 16) amounted to €180.7 million (8.6% of revenue). Working capital requirements increased by €31.6 million as a result of organic growth and the seasonal increase in DSO.

Taxes paid amounted to €36.8 million, while Capex remained low (€8.1 million, or 0.4% of revenue).

Consequently, free cash flow amounted to €104.3 million, or 4.9% of revenue, a significant increase of 33%. After taking into account net financial investments (€73 million), dividends paid (€51.5 million), the share buyback programme (€65 million), and other financing flows (+€7.9 million), net cash stood at €313 million at end-June 2026.

ALTEN therefore has significant investment capacity (gearing: -14.0%).

EXTERNAL GROWTH:

2 acquisitions

  • A company specialized in IT Services in France (90% of revenue) – (revenue: €68 million, 470 consultants).
  • A company specialized in the automotive sector (mechanical design & software-defined) in Germany (revenue: €22 million, 230 consultants).

1 disposal

  • A company specialized in Life Sciences internationally – (revenue: €11.5 million, 61 consultants).

2026 OUTLOOK:

This half-year confirmed the improvement in activity observed since the final quarter of 2025, particularly in the Aerospace & Defence sectors, which recorded strong growth.

Although the macroeconomic and geopolitical environment remains uncertain, assuming conditions remain unchanged, ALTEN is once again raising its outlook for 2026. Organic growth at constant scope and exchange rates is expected to be between 1.7% and 1.9%.

The operating margin on activity will be higher than in 2025 and is expected to be approximately 9.2% in 2026.

APPENDIX TO THE PRESS RELEASE:

Definitions and reconciliation of alternative performance indicators with IFRS indicators

The ALTEN Group uses alternative performance indicators selected to monitor its operating activities. The Group believes that these indicators provide additional information enabling users of periodic financial information to gain a more comprehensive view of the Group’s performance. These alternative performance indicators should be considered as complementary to IFRS indicators.

Revenue growth on a constant basis (or organic growth)

Growth on a constant basis (constant scope and exchange rates) is calculated by excluding the impacts of changes in exchange rates and changes in the scope of consolidation over the period.

The impact of foreign exchange is determined by converting revenue for the period at the average exchange rate of the previous year.

The scope impact is determined by excluding, for acquisitions, revenue for the period and, for disposals, revenue for the previous period, in order to make the scope of the period identical to that of the previous period.

This indicator makes it possible to identify the Group’s intrinsic business performance over the period.

Operating Profit on Activity

Operating Profit on Activity is operating profit before expenses relating to share-based payments, gains or losses on disposals of significant assets, goodwill impairment, and other significant and unusual items recorded under other operating income and expenses.

As share-based payment expense can vary significantly from year to year, this measure, presented in the financial statements, provides a direct view of the Group’s operating performance and makes it comparable from one period to another.

Net cash (or Net debt)

Net cash, as defined and used by the Group, corresponds to cash and cash equivalents less gross financial debt (bank overdrafts, bank borrowings and other similar financial liabilities). This indicator is referred to as “net cash” when cash and cash equivalents exceed gross financial debt, and as “net debt” in the opposite situation.

Free Cash-Flow

Free cash flow corresponds to cash flows generated by operating activities less net operating investments and financing cash flows relating to repayment of lease liabilities.
