- Manager Magazin’s 2025 list, reported on October 11, finds five leading fortunes down a combined €31 billion over the past 12 months.
- The Merck family recorded the largest drop, losing €9.3 billion to €24.5 billion as weaker semiconductor and lab demand weighed on Merck KGaA’s value.
- The Reimann family’s wealth declined by €7.3 billion to about €24 billion as JAB-linked consumer assets faced softer markets.
- Logistics magnate Klaus‑Michael Kühne fell €5.5 billion to roughly €23.5 billion on lower freight rates and an estimated €500 million hit tied to the Signa collapse.
- The Henkel heirs lost €5.1 billion to around €19.5 billion, while the Porsche family fell €3.8 billion to about €15.5 billion after Porsche AG was removed from the DAX in September; the ranking also spotlights discreet dynasties such as Viessmann, Brenninkmeijer, Liebherr, and Nemetschek, plus a surge to €8 billion for the Wegmann-related owners of KNDS.
