Rockwool cuts 2025 earnings outlook on factory incident, market woes

Danish insulation maker Rockwool A/S on Tuesday lowered its full-year 2025 earnings forecast, citing an unplanned factory closure in Switzerland and challenging market conditions in several key regions.

The company now expects its earnings before interest and taxes margin to be between 14% and 15%, down from a previous forecast of below 16%.

The adjustment follows a production-related incident in October at its factory in Flums, Switzerland, where molten rock flowed onto the factory floor, halting production, the company said.

Rockwool stated that repair and import costs to supply the Swiss market from other factories will negatively impact fourth-quarter earnings.

The company also pointed to a difficult market environment, particularly in the United Kingdom, Canada, and Russia.

According to the company, the UK business faced project cancellations in the third quarter, while the Canadian construction market is suffering from inflation and trade tensions, and a downturn in Russia has accelerated.

For the third quarter, Rockwool reported that EBIT fell 14% to 150 million euros, on revenue that rose 1% to 963 million euros.

The company maintained its forecast for full-year revenue to be level with the previous year and its investment level at around 450 million euros.
