Q2 AUM update

Impax, the AIM listed specialist investor focused on the transition to a more sustainable economy, today provides an update on the development of its assets under discretionary and advisory management ("AUM") for the second quarter of its financial year.

On 31 March 2023, the Company's AUM totalled £40.1 billion, an increase of 5.7% for the quarter, which included net inflows of £326 million.

Ian Simm, Chief Executive, commented:

"Impax has delivered a solid quarter of growth, despite challenging macroeconomic and inflationary market conditions.

We have reported positive net flows as asset owners and their advisors continue to be attracted to Impax's specialist focus on investing in the opportunities arising from the transition to a more sustainable economy.

"Recent policy moves such as the Inflation Reduction Act in the US and similar measures in Europe and Asia have already attracted capital flows into many areas of the economy in which Impax invests. Companies in sustainable infrastructure, renewable energy and resource efficiency are well positioned to benefit as policymakers continue to prioritise energy security and fulfil their net-zero commitments."

The table below sets out further details of the movements in the Company's AUM for the quarter ended 31 March 2023.
