AIB Group plc (A5G.IR) - Risk Factors

• Net interest income declined 10% year-on-year to €1.874 billion in H1 2025, reflecting the persistent low-interest-rate environment and margin compression.
• Cost-to-income ratio increased to 44% in H1 2025 (from 38% in H1 2024), indicating higher operating expenses amid inflationary pressures and eroding short-term operating leverage.
• Conservative provisioning: expected credit loss (ECL) coverage stands at 1.9%, offering a buffer against downside but weighing on near-term profitability.
• Commercial real estate (CRE) exposure: concentration in CRE portfolios heightens sensitivity to property market cycles and liquidity stress in a downturn.
• Domestic competitive pressures: intense competition in the Irish market could compress margins, increase funding costs, or require higher investment in pricing and digital capabilities.
• Geopolitical and market volatility: global uncertainties may impair asset quality, increase volatility in capital markets positions and raise funding stresses for corporate borrowers.

• Liquidity and funding risk: margin pressure and market volatility can increase wholesale funding costs and shorten market access windows.
• Credit risk migration: weaker economic growth or sector-specific shocks (notably in CRE and SMEs) could elevate non-performing loans and provisioning needs.
• Execution risk: meeting growth and digital transformation targets in a competitive and regulated environment requires sustained investment and operational discipline.

AIB Group plc (A5G.IR) - Growth Opportunities

• New lending momentum: new lending increased 14% year-on-year in Q1 2025, with 38% of that increase attributable to green initiatives.
• Green & transition finance: €2.5 billion of new lending directed to green/transition projects in H1 2025, reflecting alignment with global sustainability demand.
• Housing focus: targeted €6 billion in new lending to first-time homebuyers by 2026, reinforcing market share in Ireland's mortgage market.
• Capital optimisation: a significant risk transfer (SRT) completed in December 2025 on a €2.0 billion residential mortgage portfolio, producing an estimated +25 basis points initial CET1 impact.
• Shareholder returns: resumption of interim dividends of €263 million in H1 2025, signalling confidence in capital strength and supporting investor sentiment.
• Revenue diversification: net fee and commission income rose 1% to €340 million in H1 2025, underpinned by digital channels and fee-based product expansion.

• Commercial implications: green allocation and SRT improve capital efficiency, enabling further lending while maintaining regulatory buffers.
• Revenue mix: modest growth in fee income supports a shift away from pure NII dependence as digital adoption increases cross-sell and new fee streams.
• Investor considerations: resumed dividends and visible capital actions (SRT, CET1 uplift) reduce uncertainty around payout policy and signal a pro‑shareholder stance.
