Six new asset managers become ACT signatories

City Hive has announced six new asset management names has signed up to the ACT framework; Fidelity International, Marlborough Group, PGIM, Principal Asset Management, Rebalance Earth and Robeco Asset Management. 

The groups join the ACT List, a line-up of organisations dedicated to embracing transparency in corporate culture and value. There are now 34 signatories on the list representing £12trn in assets under management, which City Hive said shows the growing dedication in the investment industry to cultural accountability.

Emma Wall (pictured), head of platform investments at Hargreaves Lansdown and chair of the ACT Stewardship Council, commented on the recent growth in Signatories: “2025 has been a rollercoaster year so far for markets – but a rocking one for ACT. Six new signatories have joined us since the start of the year, taking our total signatory firms to 34, managing more than £12trn of assets in total.

“These firms understand that transparency around corporate culture is paramount to helping analysts and investors determine the robustness of their business and depth of their capabilities. While we will always hold our founding signatories in high regard, we are thrilled that these pioneers are now increasingly mainstream.

“This is a fiduciary revolution. And we’re just getting started.”

Co-CEOs of City Hive, Bev Shah and Mandy Kirby, added: “We’ve seen a growing number of ACT Signatories from across markets, including firms with international operations or cross-border client bases. This reflects a broader recognition that the ACT framework provides a shared language and set of expectations that can help firms define, develop, and communicate their culture more effectively.”
