• High, double-digit growth of +20.1% in local currencies
• Q1 sales of CHF 2,648.0 million (+13.8% in CHF)
• Acquisition effect of 19.9%
• Negative currency effect of –6.3%
• Acquisition of Kwik Bond in the USA

  • Confirmation of 2028 strategic targets for sustainable, profitable growth

Sika can look back on a successful start to the current financial year and increased its sales in local currencies by 20.1% in the first quarter of 2024. A high acquisition effect of 19.9% contributed to the first-quarter new record sales. This was mostly accounted for by the MBCC acquisition, which was consolidated as of May 2023. Sika again succeeded in growing organically in a shrinking overall market. The strong Swiss franc provided a negative currency effect of –6.3%. In the first quarter of 2024 Sika thus generated sales of CHF 2,648.0 million, corresponding to a rise in sales in Swiss francs of 13.8%.

Thomas Hasler, CEO: “Sika got off to a dynamic start to the new financial year and made strong progress in the first quarter. As expected, the positive momentum continued for Sika. In the EMEA region the trend remains positive, and Sika made clear advances in the Americas region. By contrast, we recorded a rather slower start to the new year in the Asia/Pacific region. For 2024 as a whole we expect the construction markets to recover. With our ability to captalize on megatrends early on and provide sustainable, high-performance solutions for the many challenges faced by our customers and society, we are very well positioned to continue expanding our leading global position. The successful integration of MBCC with its complementary products and markets and highly motivated employees is generating additional growth and will enable us to further expand our market share.”
