# Action *One store a day* --- In 2011, 3i led the buyout of a Dutch discount retailer called Action: roughly 250 stores across three countries, around €700m of revenue, bought at 8.3 times EBITDA. Nothing about the deal looked historic. Fifteen years on, Action runs more than 3,300 stores in fifteen countries and made €2.4 billion of EBITDA on €16 billion of sales in 2025. It opened 384 stores that year, better than one a day, and 3i's stake is carried at nearly £24 billion, roughly three-quarters of everything 3i owns. --- The machine is the store. The format is fixed: 700 to 1,100 square metres, never on the high street, around 6,000 items across fourteen categories, 150 new lines every week, two-thirds of everything priced under €2. It runs one brand and one format, with more than 90% of the range identical in every country. A new store costs about €500k to fit out and, on 3i's own numbers, pays that back inside a year. When a box that standard repays that fast, the growth question stops being "where might this work?" and becomes "how many can we open well this year?" The economics underneath are the hard discounter's: big volumes, barely any marketing, cheap locations, standardised processes, small overheads. The demand engine is the opposite of a discounter's fixed range - two-thirds of the assortment rotates, so the weekly visit is a treasure hunt, closer to Dollarama than to Aldi. And suppliers are paid after the stock has sold, so working capital is negative and expansion generates cash rather than consuming it: [[Customer-funded growth]] run through a till. --- A conventional fund has to sell its winners on the fund's clock, and 3i's 2011 fund duly realised its Action stake in 2020 at 31 times its money. But 3i itself bought the asset onwards into permanent capital, and has spent the years since increasing its stake, billions of pounds deployed into the business it already owned and knew best, from 45% then to 65% now. Deploying capital into the thing you understand better than anyone else in the world is allowed, and almost nobody does it. --- The run is not guaranteed from here. Like-for-like growth has slowed sharply (10% in 2024, 5% in 2025, nearer 3% in early 2026), France, the largest market, has gone soft, and the remaining runway (management's own estimate of 4,650 more European stores, with a US entry planned for 2027-28) is a forecast, not a fact. A format this legible also invites copies. But the underlying idea has already proven itself twice over: find a box that pays back in a year, and understand that the cleverest allocation available is usually another box. ---
