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 31st March 2024, the Company’s AUM totalled £39.6 billion, representing an increase of 1.3% over the three-month period.

Ian Simm, Chief Executive, commented:

“I am pleased to be able to report another quarter of rising AUM in the context of sustained positive market sentiment.  Although our net flows were moderately negative, the outflows were overwhelmingly from a small number of intermediary clients largely representing European private wealth, and we again recorded an increase in the number of institutional clients, and no segregated mandate terminations.

“Following nearly two years of relative headwinds, asset owner sentiment around the transition to a more sustainable economy and associated areas of Impax expertise has improved in recent months. Looking ahead, we continue to develop a healthy pipeline of potential new business and to expand our distribution capabilities around the world.”
