On 30 September 2026 , the Company's AUM totalled £ 20.0 billion . lan Simm , Chief Executive , said : " The net outflows for the quarter were concentrated in actively managed listed equities ( ~ 75 % of AUM ) and principally reflect the ' lag effect ' of clients responding to the previous weaker investment performance of some strategies . " Between 2023 and 2025 these strategies were challenged by an equities market dominated by a narrow part of the technology sector and our thematic strategies ' investment opportunities were out of favour . " However , since the start of 2026 there has been a significant change in equities markets , with environmental themes in particular performing more strongly , as investors reconsider areas such as energy security , resource efficiency and electrification , particularly in the context of the build out of Al . " Since January many of our strategies in this area are performing positively compared to broad benchmarks and particularly so compared to peers . This demonstrates how the investment process enhancements and the refreshed portfolio management teams that we have introduced in the last two years are making a real impact . " Meanwhile , we are encouraged by the notable improvement in flows in the ' sustainability ' sector over the last year . [ 1 ] As our performance track record strengthens , we expect to see our own flows improve . " As we focus on marketing our more diversified product range , it is notable that our fixed income and systematic equities strategies continue to build their strong performance track records . In private markets , the team is seeking additional capital as it identifies investment opportunities across Europe . " Management expectations for this financial year remain unchanged .
