About Us

Impax Asset Management is an award winning, leading investment manager dedicated to investing in the opportunities created by the scarcity of natural resources and the growing demand for cleaner, more efficient products and services, through both listed and private equity strategies.

We manage c. US$3.5 billion* (£2.2 billion) for institutional and high net worth investors globally, and are committed to providing strong long-term risk-adjusted returns. Our investment team numbers 28 professionals, with an average of 18 years relevant experience.

Impax's listed equity funds seek out mis-priced companies that are set to benefit from the long-term trends of changing demographics, urbanisation, rising consumption, and the resultant increases in resource scarcity. Investment is focused on a small number of deeply researched global equity strategies across alternative energy, energy efficiency, water, waste, food and agriculture related markets.

Impax's private equity infrastructure funds follow an operationally focused, value-add strategy, investing in renewable power generation and related assets throughout Europe.

We are a thought leader in defining the markets in which we invest, for example through a partnership with FTSE to develop and manage the classification system underpinning the FTSE Environmental Markets Index Series.

Investment Philosophy

Our investment philosophy is based upon the premise that the most profitable approach to long only equity investing is to invest in companies that operate in markets where there are long term themes that underpin growth and where those companies are poorly understood and, therefore, inefficiently priced to provide opportunities for a specialist active manager to add value.  Our objective is to generate out-performance over the long term by investing in the most attractive stocks identified by our research intensive, bottom up, stock picking process.  We do not invest in companies with "average" prospects simply due to their size in the index.  The best examples of inefficiently priced growth are to be found in companies providing more efficient or cleaner delivery of key services - specifically energy efficiency, alternative energy, water treatment, water infrastructure and waste related markets.

Companies in these markets are generally characterised by high levels of corporate activity, low levels of sell-side coverage, rapid technological innovation and regulatory momentum.  This means that the sectors we invest in are complex to understand and challenging to navigate, leading to a prevalence of mis-pricing that Impax seeks to exploit for its clients through a specialist focus and expert team.
