Most assets are held through holding entities registered in Germany and Luxembourg, with a smaller allocation to listed securities in Frankfurt, London, and New York. Because the portfolio is not fully public, precise breakdowns rely on regulatory disclosures, corporate filings, and occasional media interviews. SEC EDGAR 13F filings

Market Valuations and Portfolio Performance
Public market exposure within the portfolio is relatively small, which means stock price movements have a limited impact on overall net worth compared to private valuations. Latest available data suggests that technology holdings have appreciated in line with sector trends, while logistics and manufacturing positions have remained stable. The family office has not issued a public net worth statement, so all figures should be treated as informed estimates based on available disclosures.
