ROCKWOOL releases Q1 2025 results

May 19, 2025

Revenue developed well with solid profitability in Q1 2025.

“ROCKWOOL continued to perform well in the first quarter, both on revenue and profitability, effectively navigating macroeconomic turbulence. Our business continues to show a positive development across all key indicators while we achieve good revenue growth across all regions except Eastern Europe. Investments in capacity are progressing with new sites in the United States, Romania, and India as well as other projects in various development phases in Europe. We expect to see continuous demand for our energy efficient, fire safe solutions in Europe as member states define their national renovation plans to meet the mandatory targets established by the Energy Performance of Buildings Directive”.

Highlights

Revenue in Q1 2025 reached 959 MEUR, an increase of four percent measured in both local currencies and reported figures compared to last year. Two percentage points of the increase derived from the two acquisitions made in October 2024.
EBITDA in Q1 2025 reached 223 MEUR, with a 23.2 percent EBITDA margin, down 0.3 percentage points compared to Q1 2024. Earnings continued at a good level, as sales prices and input costs overall remained stable.
EBIT increased one percent to 154 MEUR in Q1 2025. EBIT margin reached 16 percent down 0.5 percentage points compared to Q1 2024, mainly due to higher depreciations related to investments. Acquisitions had limited impact on the EBIT margin.
