Investor AB is a prominent Swedish industrial holding and investment company that serves as the primary investment vehicle for the Wallenberg family. The company's business model is centered on active, long-term ownership, creating value through board representation, industrial expertise, and financial strength. Investor AB's portfolio is organized into three main business areas: Listed Companies, Patricia Industries, and Investments in EQT. The Listed Companies segment constitutes the majority of its assets and includes significant minority stakes in major global corporations such as Atlas Copco, ABB, AstraZeneca, SEB, Ericsson, and Epiroc. Patricia Industries focuses on investing in and developing wholly-owned unlisted companies, primarily in the healthcare and technology sectors, such as Mölnlycke and Permobil. Additionally, Investor AB holds a strategic stake in the global private equity firm EQT, which it helped found in 1994, and invests in its various funds. Geographically, while the company is deeply rooted in Sweden and the broader Nordic region, its portfolio companies operate globally, providing Investor AB with substantial international exposure, particularly in North America and Europe. The company's competitive position is underpinned by its permanent capital base, extensive network, and century-long track record of building market-leading businesses.
