European hard discount is not a segment in transition — it is the transition. Aldi, Lidl, and the cohort of discounters behind them are reshaping every grocery market they operate in, compressing traditional retailer margins, redefining private label share benchmarks, and building logistics infrastructure that gives them structural pricing advantages conventional grocers cannot replicate. This tracker gives strategy directors, FMCG suppliers, and investors the definitive 2026 baseline: store counts by banner across 9 markets, net opening forecasts for the year, and three strategic reframes that should change how you think about the channel.

Germany: the floor is not a floor
The dominant European hard discounter market is simultaneously the most mature and the most contested. Aldi Süd and Aldi Nord together operate 4,200+ stores in Germany. Lidl Deutschland has ~3,250. Penny (Rewe Group) has ~2,850. Norma has ~2,900. Add Action's 580, and you have a market where hard discount accounts for an estimated 28–30% of total grocery spend — a share that continues to grow as mainline grocers (Edekaan, Rewe, Real, Globus) lose share to the discounter format.
The commonly cited "floor" for discounter penetration in Germany — 30% of the market — is not a structural ceiling. It is a share-level that discounters reached during the 2008 financial crisis and from which they have never retreated. Every subsequent economic shock (Eurozone debt, COVID supply chain disruption, energy crisis) has pushed more consumers to discount formats. The floor becomes the new baseline.
Norma's position is instructive: a family-owned discounter with ~2,900 stores in Germany, Belgium, France, Austria, and Poland, that has survived and grown despite having no global parent behind it. Norma's 2026 net opening forecast of +20 is modest — it lacks the capital of Schwarz Group or the Aldi families — but it shows that the hard discounter format is not exclusively the domain of billion-euro groups. The format itself is the competitive advantage.
The UK: Lidl's structural moment
Lidl GB now operates 1,000+ stores, having added 19 in a single eight-week burst earlier in 2026, then announcing a further 50+ openings in the next 12 months (with £600m committed capex). This is the fastest store-opening velocity of any UK grocer at present. Aldi UK sits at approximately the same store count with a stated 1,500-store target.
The UK story is not about the discounters competing with each other — it is about Lidl displacing Morrisons in the Big Five ranking. Asda is at 11.6% market share. Lidl has reached 8.4%. Morrisons has been displaced as the fourth-largest UK grocer, a ranking it held for most of the 2010s. The combined Aldi + Lidl share of ~17–18% remains well below the 25%+ discounter penetration typical in Germany, Austria, and the Benelux — meaning the UK growth runway remains open-ended, constrained primarily by planning permissions and site availability, not by consumer demand.

Action and Mere: the non-food discounter wildcard
The two most aggressive 2026 net opening forecasters in the European hard discounter space are not food discounters. Action (Netherlands-founded, ~2,550 European stores, estimated 2026 net +210 openings) operates a non-food heavy discount format averaging 6,000+ SKUs across household goods, DIY, seasonal, and food-adjacent categories. Its stores have the price architecture of a hard discounter (€1.29, €2.49, €4.99 price points) but the category breadth of a discounter.
Action's expansion is not competing with Aldi — it is occupying adjacent territory in the consumer's weekly shop that traditional grocers have ceded. Its 2026 net opening forecast of +210 is the highest of any discounter on this tracker. In Germany, it has reached ~580 stores and continues opening at pace. In France (~620 stores), it is the fastest-growing discounter by store count in the market.
Mere (Siberian origins, hard discount, owned by the Moshchenko family) operates ~1,200 stores primarily in Russia, Eastern Europe, and expanding into the Balkans. Its 2026 net opening forecast of +180 is driven by expansion in Romania, Serbia, and Bulgaria — markets where the hard discounter format has not yet reached saturation. Mere's model is aggressively low-cost: smaller stores, minimal fresh, hard discount on non-perishables and household goods. The competitive risk for Action is not branded food — it is the discount non-food catchment.

|---|---|---|---|---|
| ACTION | +210 | +8.9% | DE, FR, ES, IT, PL, RO, NL, AT | Non-food discounter, fastest-growing by net openings; targeting underserved non-food catchment |
| MERE | +180 | +17.6% | RO, RS, BG, Eastern Europe | Hard-discount non-food, aggressive Eastern Europe expansion; market entry mode |
| LIDL | +160 | +2.0% | UK, ES, IT, PL, FR, NL, DE, RO | UK acceleration most significant; mature European markets steady |
| ALDI | +90 | +0.9% | PL, DE, IT, UK, ES | Growth-with-profitability pivot; selective expansion over aggressive net build |

The Romanians: La Cocoș and Profi's continental expansion
The story outside the German discounters includes the Romanian hard discounters that have built significant Central and Eastern European positions. La Cocoș's private label strategy — a discounter format built for Romanian consumer preferences, competing with Kaufland via aggressive own-brand pricing on dairy, meat, and bakery — continues to scale across the region. Profi (part of the Mid Europa Partners-backed platform) has similarly expanded from Romanian core to CEE neighbours.
These aren't fringe players. Combined with Action's CEE expansion and the Mere + various smaller regional discounters, Central and Eastern Europe now accounts for an estimated 8–10% of total European hard discounter store count — a share that has tripled in 10 years as Aldi, Lidl, and regional players compete for the same CEE catchments.
Net openings: Action and Lidl are the story of 2026
The combined 2026 net opening forecast across all seven banners is approximately 1,700 new stores. The distribution is heavily skewed: Action (+210) and Lidl (+160) account for 44% of total openings. Mere (+180) is the highest growth rate by percentage (+17.6%) but on a smaller base.
What this means operationally: if you are a supplier negotiating ranging agreements with European hard discounters, Action's non-food category breadth and Lidl's food-format expansion in the UK and Southern Europe are the two procurement conversations worth tracking most closely. Action opens stores at a rate that creates new category slots faster than any other discounter in Europe. Lidl's expansion in Southern Europe (Spain, Italy) opens fresh and premium private label ranging opportunities that did not exist three years ago.
The strategic significance of the European Discounter Density Analysis memo is worth revisiting here: the markets where discounter penetration is still below 20% (UK, Italy, France) are the markets with the most expansion runway — and the markets where incumbents have the most to lose.
Every market where hard discount sits below 25% has structural expansion runway. The UK (17–18% combined Aldi+Lidl), France (~16%), and Italy (~22%) are the three markets with the most consumer-switching headroom left. Strategy directors at incumbents: your margin compression pressure does not decrease until discounter share stabilises — and it has not stabilised in any of these three markets. If you're building a 3-year plan, assume further discounter share gains in each.
Traditional grocers ceded non-food household goods, DIY, seasonal, and discount general merchandise to the discounter channel over the past decade. Action has built a 2,550-store European estate filling that gap. If you are a Tesco or Carrefour planning director, the question is not "how do we compete with Action?" — it's "why did we leave that category space to them?" Action's +210 net opening forecast is a proxy for the non-food retail margin that mainstream grocers surrendered.
Aldi is not running the same expansion playbook it ran in the 2010s. Its +90 net opening forecast vs Lidl's +160 is not a function of capital constraint — it reflects a deliberate pivot toward growth-with-profitability as its UK and German estates mature. This matters for suppliers: Aldi's procurement team will be under margin pressure from its own profitability mandate, which means harder commercial negotiations on ranging and listing fees. If you supply Aldi, expect your commercial terms to be renegotiated this year.
