On 28 April 2026, Brazil’s supermarket industry presented a number that would place it among the country’s largest economic systems in its own right. Food retailers generated R$1.1451 trillion in revenue during 2025 across cash-and-carry, supermarkets, neighbourhood stores, convenience, e-commerce and fresh-produce formats. That represented 9.02% of national GDP and a 7.32% nominal increase in a year when the largest chains kept opening stores, absorbing acquisitions and extending their reach into services.
The first months of 2026 made that growth story considerably harder to read. Assaí and Grupo Mateus increased reported revenue, yet both recorded negative comparable-store sales as prices for rice, beans, sugar, milk, flour and other staples fell. Carrefour’s Brazilian sales declined on a like-for-like basis, even as Atacadão gained share and Sam’s Club grew. Overall food inflation accelerated again in May, but it did not restore volume uniformly across the basket. Different product groups, income levels and regions were moving in different directions.
Brazilian food retail in 2026 is therefore not a simple expansion market. It is a test of whether scale can be converted into cash, margin and customer relevance when lower-income households remain indebted, interest costs are high and price movements no longer lift every category together. Cash-and-carry still shapes the competitive field, but private labels, pharmacies, financial services, digital delivery and new labour models are changing what a productive store looks like.
A trillion-real market is growing faster than household demand
The industry’s size is real, but the headline revenue figure partly reflects a very broad definition of food retail. It includes the major national chains, strong regional groups, independent supermarkets, minimarkets, convenience stores, online operations and produce specialists. More than 424,000 stores participate in the market. That depth gives manufacturers enormous route-to-market reach, yet it also means national statistics can hide sharp differences between formats and regions.
Carrefour Brasil retained first place in the 2026 industry ranking with 2025 revenue of approximately R$123.6 billion. Assaí followed at R$84.7 billion and Grupo Mateus at R$43.5 billion. Supermercados BH, which has been expanding beyond its Minas Gerais base, reached roughly R$25.7 billion, while GPA generated about R$20.6 billion. The top three alone accounted for around 22% of the industry total, leaving substantial space for regional operators but giving the leaders exceptional buying power.
“O varejo alimentar brasileiro vive um novo ciclo de crescimento, com ganhos de eficiência, inovação e proximidade com o consumidor,” ABRAS president João Galassi said when the association released its 2026 ranking through ABRAS. The statement captures the industry’s confidence, but the individual company results show that efficiency is doing more work than demand in sustaining that confidence.
Household food consumption grew by 3.68% in 2025 after a similarly strong 2024, helped by employment, income transfers and a real increase in the minimum wage. Retail sales volumes for hypermarkets, supermarkets, food, beverages and tobacco advanced by only 0.8% over the full year. Nominal revenue for the same category rose 6.4%, showing how much of the sector’s apparent expansion still came through price and mix rather than additional physical volume.
That distinction matters to suppliers. A market can grow in reais while purchase frequency, units per basket or premiumisation weakens. The same tension appears in Xtra Food’s analysis of commodity-price relief and food-industry margins: a lower input or shelf price does not automatically produce a proportional recovery in volume, particularly when household credit is constrained.
Cash-and-carry is gaining share without escaping the volume squeeze
Assaí’s first-quarter numbers provide the clearest view of the pressure inside the atacarejo model. Gross revenue increased by 1.7% to R$20.6 billion, but comparable-store sales declined by 0.9%. A group of essential commodities in its basket experienced average deflation of about 12%, including rice, beans, sugar, soya oil, wheat flour and long-life milk. The retailer gained 0.3 percentage points of market share on a same-store basis, yet the price environment prevented that gain from translating into stronger reported growth.
The financial response was restraint rather than aggressive expansion. Assaí maintained an adjusted EBITDA margin of 5.5%, generated R$2.2 billion in free cash over the preceding 12 months and reduced leverage to 2.52 times net debt and discounted receivables over adjusted EBITDA. Only one store opened during the quarter, bringing the network to 313 locations after 11 additions over 12 months. The company is allowing the 141 stores opened during the past five years to mature while directing more cash towards the balance sheet.
Carrefour’s Brazilian business faced a similar market with a different portfolio. Group sales in Brazil fell by 0.8% like for like during the first quarter. Atacadão declined by 1.0%, although it continued to gain share, while Carrefour Retail fell by 2.2% overall. Food sales inside the retail format increased by 2.8% and volumes were positive, but non-food e-commerce was deliberately reduced to protect profitability. Sam’s Club moved in the opposite direction, growing 5.7% as active membership and volumes increased.
These results show why cash-and-carry can no longer be treated simply as a low-cost warehouse with large packs. Brazilian households now represent a large part of the customer base, while restaurants, independent grocers and other professional buyers still need trade quantities. Retailers must serve quick top-up trips, family baskets and business procurement through the same property without allowing additional services or assortment complexity to erode the cost structure.
The operational questions examined in Xtra Food’s earlier coverage of supermarket format economics become more demanding at national scale. Space allocation, checkout design, fresh-food service, pack architecture and local pricing have to vary by catchment, even when procurement and systems are centralised.
Regional consolidation is shifting the centre of growth north-east
Grupo Mateus illustrates how Brazil’s regional leaders can grow faster than the national groups while facing greater integration risk. First-quarter net revenue rose by 12.9% to R$9.4 billion after the combination with Novo Atacarejo and continued store expansion across the North and North-east. The group ended the period with 306 units after four openings and generated R$323 million in cash.
Organic performance was much weaker than the consolidated figure. Comparable-store sales fell by 7.3%, while net profit attributable to the group declined by 21.8% to R$212.9 million. Food deflation, household indebtedness and a deliberate reduction in lower-return counter sales all weighed on revenue. The company improved gross margin but could not prevent lower operating leverage from reducing earnings.
The acquisition logic remains powerful. Novo Atacarejo adds density in Pernambuco, Paraíba and Alagoas to a business already strong in Maranhão and Pará. Greater regional concentration can support fuller distribution centres, shorter transport routes, local purchasing and more effective media spending. It also gives national suppliers a larger single customer through which to reach markets that are difficult to serve from the South-east.
Physical expansion continues where management sees that density. A Mix Mateus unit opened in Caxias, Maranhão, in March with 3,604 square metres of selling space, more than 300 parking places and 23 checkouts. It created more than 250 direct jobs and took the group to 304 stores at the time. The numbers are not merely construction details: parking, checkout capacity and employment determine whether a regional atacarejo can process high-volume family and trade baskets without creating a service bottleneck.
Integration is now the more important measure than store count. Grupo Mateus has been reducing headcount in its legacy operations, slowing openings and pushing a productivity programme while combining systems and formats. Suppliers should expect assortment rationalisation and tougher negotiations as the group removes duplicated costs. Regional access remains attractive, but listings will increasingly be judged across the combined network rather than banner by banner.
GPA is sacrificing digital volume to improve revenue quality
GPA occupies a different position from the cash-and-carry leaders. Its Pão de Açúcar, Extra Mercado and proximity formats serve more frequent missions, with a greater role for premium products, fresh food and smaller baskets. First-quarter sales reached R$4.83 billion, 5.2% below the previous year, but the decline was heavily influenced by the closure of the Aliados direct-sales model for small merchants and changes in the store portfolio. Excluding Aliados, comparable sales increased by 0.6%.
Pão de Açúcar comparable sales grew by 0.2%, Extra Mercado by 1.2% and proximity by 0.3%. Perishables performed better than the rest of the assortment across the main banners. That resilience reinforces the strategic value of fresh categories, where quality, availability and service can create a stronger reason to choose a supermarket than branded packaged goods sold through several competing channels.
Digital sales demonstrate the same preference for quality over headline volume. E-commerce revenue fell by 7.7% to R$542 million as GPA reduced exposure to third-party marketplaces and concentrated on its own first-party channel. Marketplace demand can expand reach quickly, but commissions, promotional funding, picking costs and weak ownership of customer data can turn digital growth into a low-return transaction.
The shift matters for brands as much as for the retailer. A supplier may gain visibility on a delivery platform while losing control over availability, substitution and promotion. Retailers that pull demand back into their own channel can build better customer data and protect margin, but they must fund traffic, fulfilment and service themselves. Brazil’s grocery market is large enough for both models; the decisive question is which orders remain profitable after every operational cost is included.
Private labels and services are redrawing the atacarejo proposition
The clearest strategic change in 2026 is the expansion of the offer around the basic grocery basket. Carrefour introduced Bulnez as an entry-price private label and reached 70 stock-keeping units by the end of the first quarter. Assaí began launching its own consumer-facing and professional ranges, including Chef products aimed at business customers and Econobom value lines. Private label gives both groups another instrument for price positioning when national brands become too expensive or promotional funding weakens.
This is not simply a cheaper substitute strategy. Assaí has created a dedicated private-label structure and is extending the portfolio into bakery, frozen food and seasonal products. Its annual plan ties the programme to supplier standards, responsible sourcing and margin improvement. Manufacturers seeking access will face the commercial opportunity of national volume alongside the operational burden of specification, audit, packaging and service-level compliance.
The same dynamic is visible in private-label requirements for food suppliers. Winning a contract depends on traceability, continuity and category economics, not only a low ex-factory price. In Brazil, the retailer’s knowledge of regional tastes and price points can make private label especially effective, but only if product consistency survives a vast and uneven distribution network.
Services are expanding in parallel. Assaí operated 775 in-store service units in the first quarter, 21% more than a year earlier, across butcher counters, bakeries, cafés, cold-cut counters and other concessions. Its Passaí card reached 1.3 million active accounts and generated 5.4% of sales. Carrefour’s Brazilian credit portfolio grew by 15%, while billings increased by 6%. These businesses increase frequency and loyalty, but they also add labour, food-safety and credit risk to a format built around simplicity.
Pharmacy is the next test. Assaí plans to open 25 own pharmacies during the second half of 2026. A new federal law now permits a pharmacy or drugstore inside a supermarket, provided it operates in a segregated space with proper storage and a qualified pharmacist present throughout opening hours. Food retailers gain a high-frequency category and another reason for consolidated trips, but the format requires clinical governance and regulated inventory that cannot be managed like ordinary shelf merchandise.
Digital grocery is becoming a store-productivity business
Online grocery remains a single-digit share of the Brazilian market, yet the strategic activity around it accelerated in 2026. Assaí expanded its iFood partnership to more than 100 stores, roughly one-third of its network, and reported that last-mile sales more than doubled. The stores act as local fulfilment nodes rather than relying on a separate nationwide warehouse system, allowing the company to add digital reach without duplicating its physical inventory.
That model transfers pressure to store execution. Availability must be accurate, substitutions need commercial rules and picking cannot interfere with customers in the aisle. A low-price delivery order becomes unattractive if staff spend too long locating products or if a missing item forces a refund. The economics depend on basket size, picking productivity, platform commission and delivery density in each catchment.
iFood’s acquisition of a stake of less than 5% in rapid-grocery operator Daki adds another layer. Daki had reached financial break-even and approached R$1 billion in annualised revenue when the agreement was announced in May. It plans to open additional hubs and expand beyond São Paulo and Minas Gerais. The partnership combines a large demand platform with a specialised grocery inventory model, creating another competitor for the most urgent and convenience-led missions.
Checkout automation is developing alongside delivery. Assaí had 1,678 self-checkouts in 304 stores at the end of the first quarter, up from 398 machines in 73 stores a year earlier. The units process smaller baskets while traditional lanes remain essential for bulky trade purchases. This is a practical division of customer missions, not technology installed for its own sake.
The same principle should govern the use of AI in food-industry operations. Brazilian retailers have rich transaction, loyalty, delivery and regional pricing data, but value appears only when those signals improve labour scheduling, availability, promotion or waste. A digital channel that adds revenue while reducing store productivity is not an omnichannel success.
Tax, pharmacy and labour changes are moving into store operations
Brazil’s consumption-tax reform entered its test year in 2026. The new federal CBS and state-municipal IBS are being tested at rates of 0.9% and 0.1%, with offsets against existing PIS and Cofins and a waiver of the test collection for companies that meet the required reporting obligations. For food retailers, the immediate challenge is not the final tax burden but the accuracy of product classification, invoices, credits, supplier records and point-of-sale systems during transition.
The commercial effect reaches beyond the tax department. Retailers manage thousands of items with different fiscal treatments across states, promotions, bundles and private labels. A classification error can distort margin at item level or interrupt electronic invoicing. The transition also affects negotiations because suppliers and retailers need to agree how credits and tax changes flow into net prices.
The pharmacy law creates a second implementation programme. Store layouts must provide an independent area, controlled storage conditions and pharmaceutical supervision. Digital ordering and delivery are permitted, which allows retailers to connect the new category to their existing apps, but medicine cannot simply be added to an open supermarket shelf. The opportunity is a broader one-stop trip; the constraint is an operating model with different professional, sanitary and traceability requirements.
Labour scheduling is changing from another direction. Grupo Supernosso tested a five-day, two-day-off schedule with 500 employees in three Minas Gerais stores and began extending it across 45 Supernosso and Apoio Mineiro locations. Weekly hours remained at 44, but daily shifts increased while some stores closed one or two hours earlier. The pilot recorded no loss of sales and reduced certain transport and meal-benefit costs.
The experiment is commercially relevant in a labour-intensive industry where weekend coverage, absenteeism and turnover affect service. Scheduling software helped organise the new rosters, but the real decision involved opening hours, staffing peaks and employee retention. A shorter trading day can improve productivity if low-value hours are removed; it can also surrender demand if competitors remain open. The answer will vary by location rather than by national policy alone.
The 2026 winner will convert scale into controllable economics
Brazilian food retail has entered 2026 with exceptional scale and no guarantee that scale will translate into easy growth. The sector’s trillion-real revenue sits beside negative comparable sales at major chains, deflation in staples, renewed food inflation elsewhere in the basket and pressure on lower-income households. The result is a market where nominal growth, physical volume and customer welfare can point in different directions at the same time.
Carrefour and Assaí are using national purchasing power, financial services and format breadth to defend share. Grupo Mateus is extending a regional consolidation model while absorbing the operational cost of integration. GPA is reducing channels that do not meet its return requirements. Supernosso is testing whether labour redesign can improve retention and costs without losing sales. These strategies are different responses to the same problem: additional revenue is valuable only when the store, supply chain and balance sheet can support it.
For manufacturers and distributors, Brazil remains too large to approach with one national proposition. Cash-and-carry needs trade packs and sharp opening prices, premium supermarkets need differentiated products and perishables, regional chains need dependable logistics, and digital channels need accurate availability. The commercial discipline discussed in Xtra Food’s analysis of tax and distribution in Brazil applies across food categories.
The decisive indicators for the rest of 2026 will be comparable volumes, margin after promotions, store maturity, free cash flow, delivery profitability, private-label repeat purchase and productivity per labour hour. Store openings and total revenue will remain visible, but they are no longer sufficient proof of progress. The strongest retailers will be those that know which customers, channels and services create economic value in each region—and are prepared to withdraw from the ones that do not.
