In short: 3i's largest investment and effectively the whole thesis: "This growth is mainly driven by its non-food retail chain. This chain has grown its sales from €718 million to €16,000 million since 2011. An amazing yearly growth rate of 25% (!)." The results-day setback is also Action's: like-for-like growth of 2.4% against 6.8% a year earlier, "mainly in France and Germany the growth was lower than expected", with management flagging some inflation from the Middle East but easier comparables in the second half.
In short: Private; 3i Group's crown jewel and the whole of its Best Buy case. Sales of €16bn in 2025. The two worries: French like-for-like growth slowing to 2%, and a €400m US expansion targeting the Southeast in late 2027 that the market fears will fail as other European retailers have. The defence is the operating model — "Scale Economies Shared… exactly the same model that made companies like Amazon and Costco so successful" — and the framing is that you pay for Europe and get America free.
Action is the European discount chain that makes up almost all of 3i Group's value. It sold €16 billion of goods in 2025 and keeps opening stores at a remarkable rate.
Two worries knocked the shares. Growth in France, its second-largest market, slowed to 2%, which made people wonder whether Europe is running out of room. And Action is spending €400 million to open in the southeastern United States from late 2027 — a move European retailers have historically got badly wrong.
The defence rests on how the business actually works. Because it buys in vast quantities, it can sell cheaply; cheap prices bring more customers; more customers mean even larger orders and lower costs, which fund lower prices again. Economists call this scale economies shared, and it is the same engine behind Amazon and Costco. One slow year in one country does not break it.
In short: Private; the reason 3i Group is a buy candidate. "3i owns Action, Europe's fastest-growing discount retailer. Action opens hundreds of stores per year with remarkable consistency", and the three things worth watching are named as store openings, margins and long-term value creation rather than the quoted share price.
In short: Private; 3i Group's dominant holding and the reason to own it. European non-food discount retailer, revenue CAGR since 2011 of 26%, ~90% of 3i's private-equity returns, and unit economics that fund their own expansion — a ~€500k store payback in under a year, roughly one opening per day. Runway named: the UK and Scandinavia have no stores at all. The moat is described as scale-into-price: bigger buying power → lower prices → word of mouth → no advertising spend → more scale.
Action is a European chain of discount stores selling cheap non-food goods — the sort of shop where nothing costs much and people leave with a basket full of things they did not plan to buy. It is not listed; the way to own it is through 3i Group, which holds the controlling stake.
Its growth has been extraordinary and steady: revenue compounding at 26% a year since 2011, roughly one new store opening every day. The reason it can grow that fast without raising money is that a new store costs about €500,000 and pays that back within a year, so profits from existing stores fund the next batch.
The competitive loop is simple and self-reinforcing: buying in enormous volume lets it undercut everyone, low prices spread by word of mouth so it barely advertises, and the savings go back into lower prices. There is a lot of room left — several European countries, including the UK and the Nordics, have no Action stores at all.
