Simply Wall St·08/24/2026 12:26:58
Listen to the news

Rockwool (CPSE:ROCK B) moved into focus after reporting second quarter and half year 2026 results, with higher sales and revenue but lower net income, along with a higher full year revenue growth guidance range.

See our latest analysis for Rockwool.

At a share price of DKK202.8, Rockwool has seen a 2.22% 1 day share price return but is still down 9.61% year to date, while the 3 year total shareholder return of 30.77% contrasts with a 14.59% decline over the past year. This suggests recent momentum has faded despite a longer term gain, and that the latest earnings update and higher revenue guidance are being weighed against weaker net income.

to long-term.
