AJ Bell plc (AJB.L): How It Works

• Founded: 1995; floated on LSE: 2018 (AIM/Main Market transition history held in corporate filings)
• Headquarters: Manchester, UK
• Primary customer segments: Direct retail clients, financial advisers, third‑party institutions

• AJ Bell Platforms: custody, administration and reporting for SIPPs, ISAs and GIAs across self-directed and adviser-led accounts.
• AJ Bell Investments: discretionary and multi-asset investment management solutions used on-platform and by third parties.
• AJ Bell Securities: execution-only stockbroking and trading infrastructure for client transactions.
• AJ Bell Platinum: bespoke advisory and managed-service solutions for high‑net‑worth or complex clients.
• AJ Bell Media: financial publishing and content services generating advertising/subscription and distribution revenue.

• Platform fees - percentage-based charges on Assets Under Administration (AUA) for SIPPs, ISAs and GIAs; the company typically charges tiered ongoing fees that scale with client assets.
• Investment management fees - recurring management charges from AJ Bell Investments for discretionary and model portfolio services, usually expressed as basis points of assets under management (AUM).
• Trading and dealing fees - execution fees, commission and FX/instrument spreads collected by AJ Bell Securities when clients place buy/sell orders.
• Third‑party SIPP administration fees - outsourced administration income from financial institutions and advisers that use AJ Bell's SIPP platform and back‑office services.
• Publishing and media income - AJ Bell Media earns via sponsored content, advertising, subscriptions and distribution agreements.
• Bespoke and advisory services - higher-margin, tailored services via AJ Bell Platinum and consultancy projects for corporate or adviser clients.

• Platform income is the largest single contributor, driven by AUA growth and the blend of adviser‑led vs direct clients.
• Investment management income grows with flows into AJ Bell Investments' model portfolios and discretionary propositions.
• Trading income correlates with market volatility and client activity (higher trading days increase dealing fees).
• Third‑party administration and Platinum services are higher‑margin, smaller-volume revenue but important for diversification.
• Media revenue is modest versus core platform but enhances brand, lead generation and cross‑sell opportunities.

• Scale effects: fixed‑cost technology and admin base means incremental AUA growth is high-margin once breakeven is passed.
• Fee compression risk: competitive pressure can reduce headline platform fees, mitigated by upsell to advisory services and AJ Bell Investments products.
• Transaction mix: shift to passive, low‑turnover products reduces trading revenue but stabilizes recurring platform fees.
• Retention and flows: net inflows (new client deposits and market performance) are critical to maintain AUA and recurring fees.

• Increase AUA via net new client acquisition and adviser market share gains.
• Cross‑sell AJ Bell Investments and Platinum services to raise average revenue per client.
• Enhance digital tools to improve retention and reduce marginal admin cost per account.
• Win third‑party administration contracts to diversify recurring fee streams.
