Achievements

As previously announced, the Group posted growth of 5.4% in the first half of the year (including 4.6% with constant structures), despite an unfavorable economic environment.

At the end of the first half-year:

• operating profit was confirmed at 7.8% after new social security and tax charges (approximately 0.4% of revenues). It mainly reflects pressure on gross margins (price pressure, slight increase in inter-contract periods, etc.);
• net profit, group share, amounted to 5.3% of revenues;
• net cash (excluding IFRS 16 lease liabilities) increased by €25.3 million compared to June 30, 2024.

Outlook

In a persistently uncertain climate, NEURONES confirms its latest forecasts for the full year:

• revenues of nearly €850 million,

• operating profit of approximately 8%.
