Earnings per share amounted to -SEK 0.06 (-0.05)."The fourth quarter of 2025 was weaker in terms of sales than 2024, and the full year reflects a continued challenging market, not least within SurfaceCare. The decrease in revenue is mainly due to delayed launches and a weaker consumer market in the SurfaceCare business area. At the same time, we now see a clear recovery and that the trend is turning upward again," says CEO Christian Östberg.
