United StatesImpax Asset Management Group plc
(“Impax” or the “Company”)
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 first quarter of its financial year.
On 31 December 2025, the Company’s AUM totalled £24.2 billion.
Ian Simm, Chief Executive, commented:
“Net outflows during the quarter were driven by a small number of institutional clients, while net outflows in our wholesale channel continued to improve. Overall, net outflows have stabilised in recent quarters following a more challenging period around 12 months ago.
“While conditions remain challenging, we continue to see investor appetite for our investment approach and, for example, expect to onboard a new client in the second quarter within our fixed income business. This marks our first significant credit account win following the successful integration of the two teams that we have recently acquired as part of our aim to diversify our product range beyond our traditional strength in actively managed listed equities.”
