St. James's Place PLC (SJP) experienced a significant drop in its share price this week as reports surfaced about major partner firms leaving its network. Sovereign Wealth, one of SJP's largest partner firms, with an estimated $3.7 billion in funds under management (FUM) as of the first half of 2026, or 1.6% of SJP's total FUM, is reportedly exiting to join Söderberg & Partners. This departure has been described by RBC analysts as a "worrying development," especially given Sovereign Wealth's prominence within SJP's broader group.
The exodus extends beyond Sovereign Wealth, with Sheffield-based Prospera Wealth Management and Southeast-based Wellesley Investment Management also deauthorized as SJP partners. Wellesley has explicitly stated on its new website that it is now part of Söderberg & Partners, an advice consolidator that also has former SJP chief executive David Bellamy on its board. Prospera's website is currently undergoing maintenance, but a source suggests it too is joining Söderberg & Partners. These departures signal a growing trend of SJP advisers moving to other networks.
Analysts at RBC Capital Markets believe these adviser exits are a direct consequence of SJP's major overhaul to its charging structure in August 2025, which aimed for greater transparency but appears to have created "extra friction" for advisers. This change, according to RBC, has undermined a key component of SJP's "secret sauce" that contributed to its market leadership. The traditional difficulty in transferring client assets away from SJP, which previously ensured high adviser retention, is now seen as less of a barrier, suggesting a weakening "pulling power" of the SJP platform.
