The brand of Edinburgh-based international asset management firm Stewart Investors is to disappear as its Australian parent company First Sentier moves its investment management responsibilities to affiliate investment team, FSSA Investment Managers.

In August, Stewart Investors said senior portfolio managers David Gait, Sashi Reddy and Sujaya Desai had left the company.

First Sentier is owned by Mitsubishi UFJ Trust and Banking Corporation and manages around £107.3 billion of assets.

On Wednesday, First Sentier said: “First Sentier Group, the global asset management organisation, today announced a strategic transition of Stewart Investors’ (SI) investment management responsibilities to its affiliate investment team, FSSA Investment Managers (FSSA), as at close of business Friday 14 November 2025 EST.

“This transition is supported by First Sentier Group’s shareholder and board and reflects the Group’s view on how best to manage this part of the business going forward.”

Harry Moore, Chief Commercial Officer and incoming Chief Executive Officer at First Sentier Group said: “Since the unexpected departure of three of SI’s senior portfolio managers in August, we have been working closely with the SI business to assess the longer-term impact of these exits.

“This has led to the transition of investment management responsibilities from SI to the FSSA business.”

First Sentier added: “Stewart Investors and FSSA Investment Managers share a rich heritage, where they operated collectively as one investment team under First State Stewart. In 2015, First State Stewart separated into two investment teams, SI and FSSA.

“First Sentier Group remains committed to supporting its clients and consultants throughout this transition and ensuring a seamless integration with FSSA Investment Managers.”
