MBB SE increases EBITDA by 37% in the first half-year and expects to achieve forecast range at the upper end

Berlin, 23 July 2025 - Based on preliminary figures, MBB SE (ISIN DE000A0ETBQ4), a medium-sized family-owned company, achieved a disproportionately high adjusted EBITDA increase of 36.8% to €76.4 million in the first half of 2025 compared with the previous year, while revenue exceeded the previous year's figure by 16.8% to €545.5 million. The adjusted EBITDA margin thus increased very significantly by 2.1 percentage points to 14.1%. The main driver of this development was the strong operating performance at Friedrich Vorwerk and DTS. In the second quarter, adjusted EBITDA grew by 40.3% year-on-year to €46.5 million and hence significantly more than revenue, which rose by 9.2% to €285.5 million. The adjusted EBITDA margin thus reached 16.4%. In addition, the Group's net liquidity at the end of the second quarter amounted to €457.4 million (31 December 2024: €553.9 million), of which €292.0 million was attributable to the holding company MBB SE (31 December 2024: €280.8 million).

Given the strong first half-year, MBB expects to achieve its forecast of €1.0 to €1.1 billion in revenue with an adjusted EBITDA margin between 11 and 14%, each at the upper end of the range.
