Financials

Three-year financials

Financial Resilience Score: 4/10

Exergi B(y)rån is a Swedish sole proprietorship (enskild firma) with no public financial statements, as such entities are not required to file annual reports with Bolagsverket. The business benefits from a very low fixed cost base as a one-person firm with no employees or office overhead, and the owner has ~40+ years of specialist expertise in energy efficiency along with relevant certifications (Swedcert/Kiwa energy expert, formerly OVK inspector). A ~35-year operational track record and established local network with municipalities, the County Administrative Board, businesses, and private clients provide qualitative stability. However, resilience is fundamentally constrained by absolute key-person risk: the business is entirely dependent on Marcel Berkelder, who graduated in 1979 and is approaching or in later career. The trajectory shows a maturing/winding-down micro-business — OVK inspection ceased in 2022, energy declaration service ceased in August 2023, and the municipal advisor role ended January 2020. The narrowing service portfolio, capped capacity at one person's hours, small rural client base in Västerbotten, and regulatory dependency all elevate risk. Without verifiable financial figures, a moderate-to-low resilience score reflects the combination of low overhead stability against high concentration and succession risk.
