• On July 24, 2025, Nabaltec has adjusted its revenue forecast for the current Financial Year 2025 downward and now expects revenue for the full year 2025 to decline by up to 2% compared to the previous year.
• In its original forecast, Nabaltec had expected revenues to increase in the range of 3% to 5% compared to the previous year. Currency effects and increased market uncertainty due to US trade policy are having a negative impact on the company's revenues. In addition, the continued weak demand for products for the refractory industry and e-mobility will impact Nabaltec AG's revenues in 2025.
• On the earnings side, Nabaltec is sticking to its previous forecast and continues to expect an EBIT margin in the range of 7% to 9% for the current Financial Year 2025.

* The forecast is based on the assumption that the economy and the industries relevant to Nabaltec will remain stable. At the time the forecast was prepared, it remains unclear at what speed or with what dynamics the economic situation will recover globally and in the markets relevant to Nabaltec. Inflation, trade barriers, high interest rates and an uncertain situation are slowing consumption and investment worldwide. In the event of continued negative economic distortions due to the geopolitical situation, negative effects on the net assets, financial position and results of operations cannot be ruled out. Furthermore, the other statements made in the outlook report remain valid.
