The firm was founded in 1916 by the Wallenberg family as a spin-out of Stockholms Enskilda Bank, and remains controlled by the Wallenberg Foundations as the long-term anchor shareholder.

Investment thesis

Investor AB deploys capital across three business areas: Listed Companies (long-term significant minority stakes in 13 publicly listed Nordic and global businesses), Patricia Industries (10 plus wholly-owned subsidiaries) and Investments in EQT (significant ownership stake). Sector focus spans industrial and engineering, healthcare and pharmaceuticals, consumer goods, financial services, defense, telecommunications, marine and energy and medical devices and life sciences. Geographic deployment is Nordic-anchored with global diversification through portfolio companies including primary positions in Sweden and Europe complemented by US exposure via Patricia Industries subsidiaries. The permanent capital model provides multi-generational ownership horizons unconstrained by typical fund duration.
