3i Group plc (III.L): How It Works

• Capital appreciation: realised gains from disposals and IPOs of portfolio companies.
• Income generation: dividends and interest from held investments (including infrastructure funds).
• Realisation proceeds reinvested into new opportunities or returned to shareholders via buybacks/dividends.
• Balance sheet leverage and liquidity management to support deal activity and follow-on funding.

• Private Equity: largest driver of group returns - value uplift in portfolio companies (notably Action) produces substantial unrealised and realised gains; fees and dividend receipts augment returns.
• Infrastructure: steadier income profile - dividends and interest provide recurring cash yield while long-term value appreciation adds capital returns.
• Realisation cadence: timely disposals (e.g., WP sale) crystallise value and can deliver premiums to prior valuations, providing cash to recycle into new opportunities.
• Balance sheet & liquidity: £1,323m of available liquidity and modest net debt (£771m) as at 31 March 2025 give 3i flexibility to fund acquisitions, follow-on investments and distributions.

• Active portfolio management - driving revenue and EBITDA growth in holdings (Action: +22% revenue, +29% EBITDA in 2024).
• Selective realisations - capturing valuation uplifts (e.g., WP sale: £280m, +18% premium).
• Sector and geographic allocation - balancing higher-growth private equity with income-generating infrastructure.
• Capital structure optimisation - maintaining liquidity and controlled leverage to amplify returns while managing risk.
