Altor is a family of private equity funds focused on investing in and developing medium sized companies with a Nordic origin. We want to create enduring values and make a real difference as a valuable partner for owners and managers in building world class companies.

We work with a Nordic team with extensive international experience in fields such as private equity, consulting, investment banking and various industrial sectors.

Leading international institutional investors have committed a total of EUR 5.8 billion to the four Altor funds.

Our investment strategy since 2003 is based on identifying and realizing sustainable performance improvements in areas such as revenue growth, margin expansion and capital efficiency. As a rule of thumb, we only invest in companies where we see a potential for the company to double the operating profit in a five-year perspective.

Altor actively seeks to build and develop businesses in partnership with the prior owners and has achieved such co-ownerships in a majority of its investments.
