United StatesFounded in 1998 and with approximately 100 investment professionals within listed equities, fixed income and private markets, Impax is one of the largest specialist investors focused on the transition to a more sustainable economy.
We believe strong investment returns can be generated by investors who better understand the opportunities and risks associated with forces shaping the future, including resource constraints, policy and regulation, technological innovation, and evolving social trends.
We believe these trends are reshaping capital markets: driving growth for well-positioned companies and creating risks for those unable or unwilling to adapt. Our investment approach seeks out high-quality companies and issuers with enduring business models and sound risk management, aiming to deliver strong outcomes for our clients over the medium to long term.
