Financial performance

ROCKWOOL navigated the external environment well in 2025 with a revenue increase of one percent in local currencies, or three percent in local currencies excluding revenue in Russia. 

Overall, sales price increases combined with resilient operations resulted in solid Group profitability, with an EBIT margin before value adjustment of the Russian business at 14.7 percent even in a year with a significant production incident and two factory closures.

Including the loss from the value adjustment of the Russian business, the EBIT margin ended at 4.6 percent. The good operational performance highlights the Group’s resilience and ability to respond to market developments.

Environmental impact

A key focus area for ROCKWOOL is to reduce the environmental impact of our energy-intensive production process while at the same time increasing the positive impact from using our products. 

In 2025, we invested 389 MEUR in decarbonisation related to new electric production lines, upgrades and conversions as well as signing two new power purchase agreements, in Poland and Spain. 

Furthermore, we strengthened our climate ambition as the Board of Directors approved an increased Science-Based Targets initiative (SBTi) commitment for the 2026 revalidation, an increased CO2 intensity reduction target, a new ratio of renewables target, and a sustainability linked incentive metric for Group Management effective from 2026.

Outlook 2026

For 2026, we expect sales prices to balance input cost inflation, while increased spending on capacity expansion, electrification, and sales and marketing activities will lift the cost base. Combined with a plan to increase sales and marketing activities in several markets to prepare for a potential uptake in construction activities in Europe, this is expected to result in an EBIT margin between 13-14 percent for 2026. Overall, total investments are expected to reach around 650 MEUR in 2026, excluding acquisitions.
