Notes to Editors - About Impax Asset Management

Impax Asset Management manages or advises on approximately £8.2 bn in both listed and private equity strategies primarily for institutional clients.

The Company's investments are based on the strong conviction that population dynamics, resource scarcity, inadequate infrastructure and environmental constraints will profoundly shape global markets, creating investment risks and opportunities. Impax expects that these trends, reflecting the transition towards a more sustainable global economy, will drive earnings growth for well-positioned companies. Impax's proprietary investment framework identifies and calibrates the rising risks and expanding opportunities from this transition, and guides the search for investments that will deliver long term outperformance.
