The financial health of Serwent A/S shows signs of recovery, with a notable gross profit of 38,486,420 DKK in 2025, up from 36,817,859 DKK in 2022. However, the company has struggled with profitability, reporting losses in the previous three years, including a significant loss of 2,843,978 DKK in 2022. Despite these challenges, equity has increased to 95,094,611 DKK in 2025, indicating a strong capital position. The company's consistent gross profit margins suggest operational stability, but the ongoing losses raise concerns about its long-term profitability and competitive position within the wastewater treatment industry.
