ROCKWOOL releases Q1 2026 results

Highlights*

• Demonstrating resilient growth despite continued geopolitical turbulence and unusual weather conditions in Europe and North America, revenue in Q1 2026 reached 906 MEUR, an increase of two percent measured in local currencies and flat in reported figures compared to last year.
• We expect that energy and raw material cost levels will remain elevated. To protect margins, we have implemented additional price increases in the range of 6-8 percent, with main impact from the middle of the year.
• EBITDA in Q1 2026 reached 187 MEUR, with a 20.7 percent EBITDA margin, a good result although down 2.1 percentage points compared to the record high quarter last year. The production incident in Switzerland and the production stop due to the electrical conversion in the Netherlands combined with continued weakness in markets in Canada and the United Kingdom impacted the margins negatively.
• EBIT decreased 14 percent to 120 MEUR in Q1 2026. EBIT margin reached 13.2 percent, down 2.2 percentage points compared to last year.
• During Q1 2026, the Group purchased 238,060 B shares for a total amount of 7 MEUR related to the share buy-back programme which ended 6 February 2026.
• Shareholders may from 19 May 2026 until 3 June 2026 request conversion of A shares to B shares. For further information please refer to https://www.rockwool.com/group/about-us/investors/conversion-shares/
• Earlier this month, ROCKWOOL signed an agreement to acquire Ravago’s Hungary-based stone wool factory. The transaction is expected to be completed in Q4 2026, subject to customary closing conditions, including relevant regulatory approvals.

Outlook 2026

• Revenue is expected to increase between 3-6 percent in 2026 in local currencies.
• EBIT margin between 13-14 percent.
• Investment level around 700 MEUR, excluding acquisitions.
