3i Group

What 3i Group does

3i Group plc is a London-headquartered, publicly listed investment company (LSE: III) founded in 1945 that invests principally from its own balance sheet across two businesses: Private Equity and Infrastructure. Through ~223 professionals in five offices (London, Amsterdam, Frankfurt, New York, Paris), it targets mid-market companies in Europe and North America with enterprise values typically of €100m–€500m, organised around four PE verticals — Consumer & Private Label, Healthcare, Industrial, and Services & Software — plus a separately-listed Infrastructure vehicle (3i Infrastructure plc).

The firm's portfolio is dominated by Action, the European non-food discount retailer, which at 31 March 2026 represented 75% of the £23.7bn total portfolio valuation, operated 3,335 stores across 15 countries, and generated £16bn of net sales in 2025. Other material holdings include Royal Sanders (European personal-care contract manufacturing, £1.2bn valuation, nine bolt-ons since 2018), AESSEAL (industrial sealing in 104 countries), BoConcept (interior design in 60 countries), Cirtec Medical, ten23 health, xSuite, Evernex and, in Infrastructure, Tampnet, Scandlines, ESVAGT, Smarte Carte and the newly agreed Lefdal Mine Datacenter (€300m majority stake). Infrastructure AUM is approximately £6.9bn, with typical equity tickets of £150m–£300m.

3i generates returns through a combination of capital appreciation on its proprietary equity portfolio, fee income from third-party infrastructure capital, and realised proceeds on exits (£1,517m of Group realised proceeds most recently). Marketing is conducted primarily through investor-relations channels, capital-markets seminars and the annual report, targeting institutional shareholders and co-investors rather than a retail customer base. Portfolio operations are highly active: 96% of portfolio companies by value grew earnings in the year to 31 December 2025, and exits in 2025 included MPM Products to Partners Group and MAIT Group to DBAG.
