Investor AB

Investor AB is a Swedish investment holding company that builds long-term value by owning and developing businesses across healthcare, industrials, engineering, financial services, and other sectors. The company operates through three principal investment areas: Listed Companies, Patricia Industries, and Investments in EQT. Through its listed portfolio, Investor AB holds significant ownership stakes in established public companies, while Patricia Industries focuses on wholly owned and other privately held businesses, and its EQT investments provide exposure to private equity and related alternative investment strategies. The company works actively with portfolio businesses through board participation, strategic guidance, operational development, and long-term capital allocation, with investments concentrated primarily in Europe and North America. Investor AB follows a long-term ownership model rather than a conventional private equity fund strategy and does not apply a single publicly disclosed set of company-level revenue, EBITDA, or enterprise-value thresholds across its diversified portfolio. Investor AB was founded in 1916 and is headquartered in Stockholm, Sweden.
