CEO comment

Commenting on the Group’s performance, CEO Jes Munk Hansen says:

“As indicated in our previously announced outlook adjustment, the volatility and hesitation we saw across many markets impacted our Q3 results. Trade policy uncertainty and geopolitical tensions persisted in the third quarter, though not all markets were affected equally. Key markets such as the United Kingdom and Canada experienced headwinds, with many large projects being postponed, while we saw pockets of good growth elsewhere, such as eastern and southern Europe. Sales in the United States are back on a good growth path.

Overall profitability was negatively affected by lower profitability in the Russian and UK businesses as well as lower operational efficiencies in several locations. The company is very robust financially, and we continue to invest in capacity expansion, decarbonisation, and digitalisation”.
