Nabaltec Q1 2025 Functional Fillers

Revenue in the "Functional Fillers" product segment increased by 4.1% yoy. Good demand for fine precipitated hydroxides and a significant higher revenue of viscosity optimized hydroxides were the basis for growth in the first quarter 2025. Boehmites, on the other hand, suffered a 42% decline in revenues compared to the previous year.

The operating result (EBIT) was with EUR 4.5 million on the same level as last year. Resulting in an EBIT margin of 11.3% in this segment (Q1/24: 11.6%). The fine precipitated hydroxides product range, together with the viscosity optimized hydroxides, contributed significantly to this result.

CAPEX in the "Functional Fillers" product segment amounted to EUR 4.6 million in the first quarter 2025. Investments in the capacity expansion of boehmites and viscosity optimized hydroxides continue to be the main capex projects.

Nabaltec Q1 2025 Specialty Aluminas

Revenue in the "Specialty Aluminas" product segment decreased by 6.1% compared to the previous year's level in the first quarter. Overcapacity and weak demand on the market had a negative impact on both sales volumes and sales prices.

The operating result (EBIT) was negative in the first quarter 2025. After a positive EBIT margin of 3.5% in the first quarter of 2024, the segment recorded a negative EBIT margin of -2.9% in the first quarter of 2025. Declining sales prices and higher energy costs were the main reasons for the negative development.

CAPEX amounted to EUR 0.8 million in the "Specialty Aluminas" product segment. The amount includes expenditure for the general overhaul of two rotary kilns.

in EUR million	3M/2025	3M/2024	Change
Net operating income	7.0	8.0	-13.2%
+/- Working capital	6.9	25.8	-73.1%
- Taxes paid	-1.0	-2.1	-51.0%

Cash flow from financing activity	0.4	0.4	-5.4%
Cash at end of the period	93.7	113.4	-17.4%

• The decline in net operating income and especially the changes in working capital had a negative impact on cash flow from operating activities in the first quarter 2025 (Q1/24 fixed deposit of EUR 15 million switched from non-current assets to cash).
• The investment focus was on expanding the capacity of boehmites and viscosity optimized hydroxides, as well as expenditure for the general overhaul of two rotary kilns and the ongoing process optimization at the Schwandorf site.
• Cash and cash equivalents amounted to EUR 93.7 million on 31 March 2025.

• The demand in 2025 will continue to be characterized by short-termism and high volatility.
• Based on the economic and industry-specific environment, the company expects revenues growth in 2025 to be in the range of 3% to 5% compared to the previous year (2024: EUR 203.6 million).
• On the earnings side, Nabaltec expects an EBIT margin in the range of 7% to 9%.

* 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.
