Founded in 1998, Impax is a specialist asset manager, with approximately £26.1 billion of assets under management as at 30 September 2025 in both listed and private markets strategies, investing in the transition to a more sustainable global economy.

Impax believes that capital markets will be shaped profoundly by global sustainability challenges, including climate change, pollution and essential investments in human capital, infrastructure and resource efficiency. These trends will drive growth for well-positioned companies and create risks for those unable or unwilling to adapt.

The company seeks to invest in higher quality companies with strong business models that demonstrate sound management of risk. Impax offers a well-rounded suite of investment solutions spanning multiple asset classes seeking superior risk-adjusted returns over the medium to long term.
