3i Group plc (III) — Investment Research Note

Executive summary

3i Group is a UK-listed permanent-capital investment company whose value is dominated by a single private equity asset — Action, the European general-merchandise discounter — alongside a smaller portfolio of mid-market PE holdings, infrastructure stakes (notably its ~29% holding in 3i Infrastructure plc), and Scandlines ferries. Across the period the picture is one of relentless NAV compounding driven by Action: diluted NAV per share rose from sub-£10 in FY21 to 1,745p at March 2023 and 1,886p at September 2023, with Action's like-for-like sales running at +18-19% and EBITDA up >40% year-on-year 2023-11 half-year. The single most important valuation point today is that 3i is, in effect, a quasi-pure-play levered bet on Action's continued compounding at a stretched 18.5× EBITDA private-market multiple — the entire investment case turns on how much further Action can run.

Fair value estimate

Methodology: Net Asset Value with a P/NAV multiple sanity check (the standard methodology for a listed permanent-capital investment vehicle). Within NAV, Action (~67% of portfolio at last disclosure) is valued via earnings multiple (18.5× run-rate EBITDA net of liquidity discount); the remainder uses earnings/DCF/NAV depending on holding.

Key assumptions (with caveats): The filings only give detailed financials up to 30 September 2023 — substantive interim/annual figures from FY24-onwards are referenced but not reproduced in this disclosure pack. I must therefore roll forward Sep-23 NAV of 1,886p using a reasonable assumption about Action's continued growth (LFL ~12-18% historically, with very strong operating leverage to scale) and the dividend trajectory (FY24 total 34.5p; FY25 total 42.5p, per AGM resolutions 2024-06 AGM; 2025-06 AGM).

• Base case roll-forward of NAV from Sep-23 1,886p, net of dividends paid: implied current diluted NAV in the range ~2,500p to ~2,900p.
• Apply a P/NAV range of 0.95×–1.10× (3i historically trades at or above NAV given Action's compounding profile).
• Fair value range: 2,400p – 3,150p per share → implied market cap £23,200m – £30,500m.
• Midpoint: ~2,775p / ~£26,800m.

Vs. latest disclosed market cap of £26,253m: The market is roughly at our mid-point. Absolute upside to midpoint: ~+2%; range: –9% to +16%. Verdict: fair, with no margin of safety either way given the wide uncertainty band.

Sector context

ICB classification of Financial Services is correct, but functionally 3i is a listed private equity / investment trust, not a bank or asset manager. Quality / NAV growth profile sits well above the typical UK financial — gearing is c.6% (vs banks at >10× balance-sheet leverage); concentration risk (~67% in one asset) is far higher than peers. Closest listed peers: HgCapital Trust (HGT), Pantheon International (PIN), ICG Enterprise Trust (ICGT), and arguably Eurazeo / Wendel in continental Europe. None has 3i's single-asset Action concentration.

Investment thesis

• Action remains a category-defining compounder: LFL sales +19.2% in the nine months to October 2023, +30% headline sales growth, EBITDA +44% to €1.53bn LTM, with operating EBITDA margin expanding from 12.2% → 13.5% as scale leverage runs through. 153 new stores added in 9M FY24 and clear runway in Italy, Spain and Slovakia 2023-11 half-year. Successful $1.5bn USD term-loan upsize at attractive pricing demonstrates institutional debt-market endorsement of the model.
• Robust permanent-capital balance sheet: Gearing 6% at H1 FY24, £955m liquidity, six-year €500m bond at 4.875% term-funded ahead of need; no forced-sale pressure 2023-11 half-year. This is what lets 3i hold Action through cycles rather than recycle at sub-optimal prices.
• Dividend trajectory underwrites a real-yield floor: Declared dividends have stepped up from 21p (FY21) → 27.25p (FY22) → 29.75p+ (FY23) → 34.5p (FY24) → 42.5p (FY25), a c.20% CAGR 2021-07 AGM; 2024-06 AGM; 2025-06 AGM. At ~2,716p, the trailing yield is ~1.6% and growing.

Key risks

• Action concentration and multiple risk: Action accounts for c.67% of portfolio value at the last disclosure, held at 18.5× run-rate EBITDA — a 1.0× multiple compression would reduce 3i's NAV by ~£749m, or ~75p per share 2023-11 half-year. Any cooling in Action's growth or a re-rating of European discount-retail comparables drops directly to NAV.
• Discretionary-consumer and cyclical PE drag: Luqom, Audley Travel, YDEON, WilsonHCG, Formel D and Tato are already flagged as underperforming on weak consumer/recruitment/DIY end-markets 2023-11 half-year; four downward multiple revisions in H1 FY24 came on top of eight in FY23.
• Limited post-2023 disclosure in this pack: 12 of the 17 filings supplied are placeholder "Doc re. ..." notices or AGM resolutions, not substantive financials. I am extrapolating NAV growth for 2.5 years and cannot independently verify Action's most recent trading — inferred risk from disclosure gap.

Operating leverage

3i is a holding-company structure with very modest direct operating leverage at the parent — operating expenses were £82m in H1 FY24 against a £20bn portfolio. The economic operating leverage flows through the underlying portfolio companies, predominantly Action. Action itself is a retail operating leverage story rather than a software-style story: EBITDA margins of 13.5% (P9 FY24, up from 12.2% PY) and sales-leverage gains as fixed central/IT/buying costs scale across an ever-growing store base 2023-11 half-year. The mechanical contribution: H1 FY24 sales +30% drove EBITDA +44% — i.e. a "delta-of-deltas" of ~1.4×, meaningful but well short of pure-software 3-5× drop-through. For 3i shareholders, the AI-cycle "long-tail revenue surprise" channel is essentially absent: even if Action sells 20% more T-shirts, EBITDA grows ~28%, not multiples thereof.

Value-trap signals

None identified. NAV growth is real, debt is modest, dividends are rising, audit is clean (KPMG unqualified), governance issues at AGMs are limited to typical ~3-8% remuneration dissent and a recurring ~7-8% vote against the chair. The pricing reflects fundamentals.

Earnings vs. expectations

3i does not issue numerical earnings guidance in the conventional sense — as an investment company it reports NAV and total return. Within that frame: H1 FY24 total return of £1,669m (10% on opening shareholders' funds) modestly trailed H1 FY23's £1,765m (14%), but the absolute NAV per share continued to compound (1,477p → 1,745p → 1,886p across Sep-22 / Mar-23 / Sep-23) 2023-11 half-year. Action specifically has materially exceeded its own internal plan — its September 2022 valuation of 18.5× rolled into 12.8× of subsequent-year run-rate one year later, i.e. growth massively out-paced the multiple 2023-11 half-year. Pattern: NAV compounding has consistently delivered to/ahead of plan; the only "miss" channel is multiple compression on the non-Action portfolio, which has been a recurring small drag.

Conviction

3 — moderate. Anchored by: (a) the methodology (NAV) is unambiguously correct for a listed investment company, (b) Action's growth profile is well-documented and audited, (c) 3i's track record of compounding NAV is unusually clean. Limited by: (a) the filings package only contains one substantive half-year report (Sep-23) — I am rolling 2.5 years forward without underlying numbers, (b) the entire valuation hinges on Action's multiple holding, which is a single subjective assumption applied to a single asset. A different observer accepting only the disclosed Sep-23 NAV (1,886p) and applying 1.0× would land at fair value c.£18bn, materially below today's mcap — so the assumed roll-forward is doing most of the valuation work.

Driver scoring (0-100)

• ai_beneficiary: 15 — A discount retailer, ferries, mid-market industrials and a few niche PE assets. No meaningful AI revenue channel; not on the picks-and-shovels side of the AI buildout.
• operating_leverage: 45 — Retail operating leverage at Action is real but moderate (EBITDA grew ~1.4× the sales delta). Holding company itself has very limited leverage. Not the "long-tail" profile this investor wants.
• earnings_surprise_trend: 60 — Action has consistently outpaced both internal valuation assumptions and its retail peer group; some PE holdings have disappointed. Net positive but qualitative.
• cyclicality: 55 — Action is somewhat counter-cyclical (value-for-money retail benefits in tough times), but Scandlines, several PE holdings, and the wider PE realisation cycle are meaningfully cyclical.
• moat: 65 — Action's scale/cost-leadership and store-density moat in European discount retail is genuine; 3i's permanent-capital structure is itself a structural advantage vs fund-life-constrained PE peers.
• leverage: 25 — Parent gearing 6%, ample liquidity, fortress structure at 3i level (look-through to PE portcos is higher at ~2.1× LTM EBITDA, but ring-fenced).
• earnings_quality: 55 — Audited and KPMG-reviewed but inherently mark-to-model on most holdings; Action is valued at a manager-selected multiple. Cash distributions exist but most "earnings" is unrealised fair-value uplift.
• management_quality: 80 — Simon Borrows has compounded NAV at an exceptional rate over a decade; capital allocation discipline (refused to over-pay, opportunistic Action top-up in October 2023) is consistent with stated philosophy.
• growth_momentum: 70 — Action's most recent disclosed growth is very strong; offsetting drag from cyclical PE holdings keeps this below the 80s.

Overall score

280 / 1000 — A high-quality compounder run by a strong team at a fair price, but a poor fit for the specific investor profile here: minimal AI-receiver exposure, only moderate operating leverage to an upside revenue surprise, and a valuation that is fairly priced rather than offering a margin of safety. The portfolio is dominated by physical discount retail — exactly the kind of business whose growth path is largely orthogonal to AI capex. Acceptable downside protection prevents a lower score; the absence of an AI thesis prevents a higher one.
