In € millions unaudited Q3 9 months 2024 2025 Δ Δ organic 2024 2025 Δ Δ organic

Industry 15.5 16.9 +8.9% +13.2% 52.3 53.4 +2.2% +3.9%

Automotive 84.6 78.6 -7.2% -3.7% 272.5 257.2 -5.6% -4.1%

Total 100.1 95.4 -4.7% -1.1% 324.8 310.6 -4.4% -2.8%

Revenue in the third quarter of 2025 came to €95.4 million, down -4.7% on the third quarter of 2024. This decrease factors in the deliberate termination of non-contributory contracts in the fluid transfer tubing (FTT) business, the restructuring of which is part of the IMPULSE 2026 plan. At constant exchange rates, the decrease was just -1.1%. When we exclude the impact of the decision to terminate the FTT contracts to help improve operating margin, activity for the quarter would have increased by +4.0%.

Activity was driven by continued strong growth in Asia and the recovery in sales in Europe. Activity for the industrial market saw a return to good sales momentum during the quarter.

Revenue for the first nine months of the year came to €310.6 million, a decrease of -4.4%. At constant exchange rates, the decrease was -2.8%. When we exclude the impact of the decision to terminate the FTT contracts to help improve operating margin, sales growth would have been +0.6%.

Outlook

Since the beginning of the year, DELFINGEN has demonstrated its ability to adapt to a volatile, uncertain and complex environment while continuing to rigorously roll out its IMPULSE 2026 roadmap. This good execution led to solid performances over the first nine months of 2025.

Thanks to its commercial positions, its global presence, its agile and decentralised organisation and its operational excellence, DELFINGEN intends to seize growth opportunities and speed up both its leadership and its diversification into higher value-added markets.

Under current market conditions, DELFINGEN is confident it will achieve a current operating margin of more than 7%, which will be a significant improvement on 2024, combined with an increase in its cash generation and a significant reduction in its debt leverage.
