Ratos AB
Ratos AB was founded in 1934 by the Söderberg family. Per-Olof Söderberg serves as chairman while Jan Söderberg holds a board seat and controls Söderbergföretagen. The family’s wealth traces to the 19th-century steel wholesaler Söderberg & Haak. The firm allocates across private equity, listed equities and real assets. It executes buyouts, growth investments, management buyouts and public-to-private transactions. Geographic reach centers on Sweden with additional European exposure through its holdings. No recent operational events from the last 24 months appear in available records. The office maintains board ties to the Stockholm School of Economics and the Stockholm Chamber of Commerce through Per-Olof Söderberg. Ratos AB operates as the primary investment vehicle for one branch of the Söderberg family, distinct from the separate Söderberg & Partners insurance platform that includes external shareholders KKR and TA Associates.
