About this investor

Partners Group invests on behalf of clients. Selected relationships here include International Schools Partnership, North Star, FairJourney Biologics and Breitling. [1][2][3][4]

These are selected investments, rather than a complete portfolio or shareholder register. Fund investments and client assets have separate ownership from the investment manager's corporate balance sheet. Each holding retains its evidence date and individual or shared investment scope. ISP and FairJourney have co-investors. Claremont and Iontas are operating businesses within those platforms. North Star supplies offshore services; it does not own the wind farms it serves. [5][6][7][2]

Each card names the entity invested in. Linked companies and brands can sit below that entity. Stakes use the source’s definition and date; disclosures are selected and do not give a complete portfolio or investor register. Read the investor methodology.

Former holdings & portfolio changes
  • International Schools Partnership

    The company report confirms CVC and Qatar Investment Authority joined in 2025 alongside Partners Group and OMERS. Partners Group retains majority ownership. The announced CVC transaction and later QIA disclosure do not establish a reconciled current individual CVC/QIA allocation. [8][5][9]

  • FairJourney Biologics

    The majority acquisition completed in 2024, with GHO retaining a minority and founder António Parada remaining a shareholder. Iontas supplies the UK laboratory connection. [7][10]

  • North Star

    Further client equity and the four-vessel acquisition were confirmed in April 2026. The vessel deal was not a purchase of Edda Wind itself. [2][11]
