The financial health of SEF ENERGI A/S shows significant volatility, with a concerning trend in profitability over the past few years. After a strong performance in 2023 with revenue of 287 million DKK and a profit of 52 million DKK, the company faced substantial losses in 2024 and 2025, reporting profits of -25 million DKK and -13 million DKK, respectively. Equity has decreased from 101 million DKK in 2023 to 59 million DKK in 2025, indicating potential liquidity issues and a weakening financial position. Despite fluctuating revenues, the company remains a notable player in the electricity trading sector, but its declining profit margins and equity raise concerns about its long-term sustainability.
