1 2 "This quarter, we were recognized as the most valuable brand in the food retail sector in Brazil by three important national rankings. This historic recognition reflects the strength of Assaí and reinforces our leadership not only in value proposition and innovation, but also in relevance and reputation. The 2Q25 results show that the Company remains focused on growing with discipline and reducing leverage. Revenues reached R$21 billion, representing a growth of 7% compared to 2Q24, with a consistent EBITDA margin of 5.7% (+0.3 p.p. vs. 2Q24). This performance was driven by the maturation of the new stores, services expansion and the strict control of expenses. In addition, for the 4th straight year, we renewed the GPTW certification as an excellent place to work and were recognized as the best in our segment in the following areas: Ethno-Racial, Women and People with Disabilities. Thank you also to all the customers, who challenge us to always do our best.” Belmiro Gomes São Paulo, August 7, 2025 Assaí Atacadista announces its results for the 2nd quarter of 2025.

For comparison purposes, in the table above, the net income for the period is also presented excluding the effect of these credits. REVENUE GROWTH, INCREASE IN CUSTOMER TRAFFIC AND SAME-STORE SALES EVOLUTION Gross sales reached R$ 20.9 billion in 2Q25 (+7.2%), representing an increase of R$1.4 billion compared to 2Q24. This result led to market share stability during the period quarterly, despite no changes in the installment purchase policy for customers. In the last 2 years, sales grew by +18.9%, an increase of R$ 3.3 billion in the period quarterly sales performance is explained mainly by: (i) the performance of 'same-store' sales of +4.6%, excluding the impacts of the calendar effect and donations made by customers for those affected by the floods in Rio Grande do Sul in May/2024. This level of sales reflects the pressure on consumers' purchasing power and the trade down of products; (ii) the contribution of 10 stores opened in the last 12 months (+2.9%); and (iii) the high attractiveness of the business model, resulting in an increase of +1.8% in customer traffic. In the quarter, the Company implemented 811 self-checkouts in 154 stores, totaling 1,209 self-checkouts and 224 stores with this functionality (vs. 7 stores in 2Q24).

The result reflects the ongoing maturation process of the new stores and the performance of 'same-store' sales of +5.0%. PHYGITAL STRATEGY: SEQUENTIAL INCREASE IN APP PENETRATION AND PROGRESS OF PARTNERSHIPS WITH LAST MILE OPERATORS The Meu Assaí App, which already has over 14 million registered customers, continues to contribute as an important role to strengthen the relationship with consumers. The information obtained through the App enables a better understanding of consumption habits to develop more effective strategies. In 2Q25, the store’s frequency by customers using the App was +59% higher than those of unidentified customers, while the average spending of these users was +33% higher. In addition, the identified revenue represented 44% of sales in 2Q25 (vs. 42% in 1Q25). Partnerships with last mile companies continue to increase sales, in addition to expanding purchase options for customers, offering convenience and ease. The agreement signed with iFood in 2024, one of the most recent advances in the phygital strategy, resulted in a 119% growth in revenue coming from last mile operators in 2Q25 compared to 2Q24. CONVERSIONS MATURATION CONTRIBUTES TO PROFITABILITY GROWTH In 2Q25, the group of 64 stores converted between 2022 and 2023 achieved an average sales per store of R$26.4 million, a level +21% higher than the average sales per store of the organic store base opened until 2022 (R$ 21.8 million). Furthermore, the productivity (sales/sqm) of the converted stores corresponds to 91% of the productivity of the organic stores opened until 2022. The EBITDA margin Pre-IFRS16 was 5.5%, an expansion of +1.4 p.p. compared to 2Q24, a level close to the Company's average, which highlights the potential of this group of stores that is still under maturation. In the quarter, the group of 47 stores converted in 2022 presented an average sales per store of R$27.9 million, +28% compared to the average sales per store of the organic base store opened until 2022. The productivity (sales/sqm) reached 94% over the productivity of the organic base store opened until 2022. The EBITDA margin Pre-IFRS16 of these converted stores reached 6.1%, an increase of +1 p.p. vs. 2Q24 and +0.4 p.p. higher than the Company's average (5.7%). The 17 stores converted in 2023, which are at an earlier stage of maturation compared to the 47 stores converted in 2022, reached an average sales per store of R$22.3 million, slightly higher than the level of the organic stores opened until 2022. Additionally, productivity (sales/sqm) was 81% compared to the productivity of the organic base store opened until 2022, with an EBITDA margin Pre-IFRS 16 above 3%. Also, the commercial galleries continue accelerating the maturation of conversions, contributing to the increase in customer traffic, generating revenue, and greater efficiency in the dilution of operational costs. At the end of 2Q25, the 2Q2 2Q25 2 2 5 5 ar re S Sales 2 s Stores o e e 2 22 era e o t l e e e rom o ers o s (1) % Net Revenue 5 occupancy rate of the gross leasable area (GLA) reached 79% (vs. 74% in 2Q24), with revenue of R$30 million (+14.3% vs. 2Q24). In 1H25, galleries revenue totaled R$60 million, an increase of +13.8% compared to 1H24. EXPANSION OF MARGINS RESULTED FROM THE IMPROVEMENT IN GROSS PROFIT AND STRICT EXPENSES CONTROL In 2Q25, gross profit reached R$3.2 billion, a margin of 16.7%, up +0.2 p.p. compared to 2Q24. In 1H25, gross profit reached R$6.2 billion, with a margin of 16.6%, up +0.2 p.p. from 1H24. The performance during the quarter was mainly due to: (i) the performance of the 94 new stores opened in the last 3 years that are still in the maturation process and represent approximately 30% of the stores base; and (ii) the constant evolution of the business model, with the expansion of the services offered in the stores, providing a better shopping experience. At the end of 2Q25, the Company operated 731 service units (+63% compared to 2Q24), being 254 butcher sections, 244 cold cuts sections, and 233 bakeries. Selling, general and administrative expenses accounted for 11.2% of net sales in the quarter, reflecting a dilution of 0.02 p.p. compared to 2Q24. The reduction is a result of disciplined expense control and the continuous maturation of the new stores, despite the implementation of more than 170 units of new services in the last 12 months and labor shortages. The equity income related to an approximately 18% stake in FIC's capital reached R$19 million in the quarter (+18.8% vs. 2Q24). The total number of Passaí cards issued reached 3.3 million units, up +15,0% from 2Q24, accounting for 5.4% of sales. EBITDA for the quarter totaled R$1.1 billion, an increase of +11.8% compared to 2Q24 and a margin increase to 5.7% (+0.3 p.p. vs. 2Q24), the highest level for a second quarter since 2Q21. In 1H25, EBITDA totaled R$2.1 billion (+12.8% vs. 2Q24) with a margin of 5.6%, an increase of +0.3 p.p. compared to 1H24. 52Q2 2Q25 mar re S 5 5 5 5 2 25 22 2 (1) % Net Revenue 6 FINANCIAL RESULT REFLECTS HIGHER INTEREST RATES The net financial result totaled R$565 million in the quarter, representing 3.0% of net sales (vs. 2.6% in 2Q24). The key impacts on the net financial result in 2Q25 are due to: (i) higher profitability of financial investments, which is the result of the increase in the average cash invested compared to the previous period (R$1.8 billion in 2Q25 vs. R$835 million in 2Q24); and (ii) increase in the Debt Burden line, due to the impact of the higher effective CDI in the period (3,62% in 2Q25 vs. 2,91% in 2Q24) and the higher volume of average gross debt in the period (R$16.6 billion vs. R$15.9 billion in 2Q24), despite a lower net debt in 2Q25 compared to 2Q24. In addition, the debt burden line includes the impacts: a. from mark-to-market, arising from swaps for CDI of debts indexed to IPCA (5 series of CRIs), pre-fixed rate (1 series of CRI) and USD (5 loan operations), with a positive non-cash impact of R$15 million in 2Q25 (vs. negative by -R$33 million in 2Q24); and b. the prepayment cost of the 4th issue of debentures in the amount of R$30 million. It is worth mentioning that the "Cost of Receivables Discounted" line reflects the total charges of the operations carried out during 2Q25. The volume of discounted receivables presented in the Net Debt table on page 10 (R$ 2.1 billion) refers only to the amount that would be due in the subsequent quarter. In addition, the amounts that would mature within 2Q25 were also paid in advance. The volume of receivables discounted depends on the Company's daily cash needs, which vary according to the amounts of the payments made (suppliers, CAPEX, debts, among other obligations).

In 1H25, net income Pre-IFRS16 was R$426 million and net margin was 1.1% (+0.4 p.p. vs. 1H24). This result reflects the operational performance, driven by the maturation of the new stores and expenses control, even in the face of high interest rates, which significantly affected the financial result. It is worth noting that in 2Q25, tax credits of R$86 million were recognized, impacting the Income Tax and Social Contribution line and, consequently, the net income. Excluding tax credits, net income Pre-IFRS16 totaled R$178 million in the quarter, with net margin of 0.9%, stable vs. 2Q24. In 1H25, net income Pre-IFRS16 totaled R$340 million, with a margin of 0.9%, accounting for an increase of +0.2 p.p. vs. 1H24. LOWER INVESTMENT REINFORCES THE COMMITMENT TO DELEVERAGING The investments (additions to property, plant and equipment) reached R$162 million in 2Q25 and R$241 million in 1H25. The reduction compared to the comparable period in 2024, mainly reflects the concentration of the store expansion in the second half of the year, besides the postponement of certain projects. This strategy is aligned with the Company's commitment to financial discipline and to the deleveraging process. The expansion schedule for 2025 remains in line with the plan, and nearly 10 stores will be opened by the end of the year. Among them, one store is expected to open in August in the state of São Paulo. et ome et mar 52 2Q2 2Q25 25 2 2 25 5 (R$ million)2Q252Q24Δ1H251H24ΔNew stores and land acquisition41 205 (164) 70 384 (314) Store renovation and maintenance91 80 11 132 121 11 Infrastructure and others30 35 (5) 39 46 (7) Gross Total Investiments162 320 (158) 241 551 (310) 8 ONE-OFF IMPACT ON SUPPLIER FINANCING FOR THE QUARTER DISCIPLINE IN RECEIVABLES POLICY The cash cycle for the quarter was 7.7 days, reflecting: (i) the temporary mismatch between the suppliers and inventories lines (supplier financing of 13.0 days in 2Q25 vs. 16.7 days in 2Q24) as result of the challenging sales environment for retail, especially in June/25. The Company’s business model enables a quick adjustment of this temporary supplier financing impact, which ended July with 41 days of inventories; and (ii) the improvement of 1.1 day in the receivables line in 2Q25 (vs. 2Q24) once the installment purchase policy for customers remained unchanged, which means that no extension of payment terms was given to customers. 25 5 5 2 5 2 5 222 25 2 22 2 25 52 52 2 2 52 2 5 5 2Q2 Q2 Q2 Q2 2Q2 Q2 Q2 Q25 2Q25S l ers e tor es e e a les a le S l er a ( uppl ers nvestor es) as le S l ers e tor es e e a les l s o te re e a les In days of COGS (Cost of Goods Sold) 9 FREE CASH FLOW TOTALS R$2.7 BILLION The operating cash generation reached R$3.9 billion, an increase of R$1.6 billion in 12 months. This result was driven by: (i) the increase of R$519 million in the EBITDA LTM compared to 2Q24. It is worth noting that 90% of the EBITDA was converted into operating cash; and (ii) due to the improvement in working capital, resulting from the evolution of the cash cycle over the 12 months ended June 2025. The free cash flow was R$2.7 billion in the last 12 months, representing an increase compared to the negative amount of R$2.2 billion recorded in the same period last year. This performance mainly reflects the reduction in the pace of expansion (CAPEX) and the EBITDA growth in the period. The total cash flow was positive at R$650 million, a significant increase compared to 2Q24 (+R$ 4.7 billion). This performance highlights the effectiveness of actions aimed at operational efficiency and strategic use of capital, as well as the ongoing commitment to financial discipline and value creation for shareholders.

The leverage level is mainly due to the increase of R$ 519 million in the EBITDA Pre-IFRS16 accumulated over 12 months, reflecting the maturation of the new stores and a reduction in net debt by R$ 200 million. With the goal of improving the debt profile, reducing the average cost and extending the term, Assaí raised R$ 1.5 billion (CDI+1.20% per year) and prepaid the 4th issue of debentures in the amount of R$2.0 billion (CDI+1.75% per year) in the quarter. Currently the Company's debt average term is 39 months with an average cost of CDI+1.28% per year. Compared to 2Q24, the reduction in gross debt in 2Q25 was R$ 1.3 billion and in net debt was R$ 200 million as a result of operational cash flow. At the end of the period, the balance of discounted receivables maturing in the subsequent quarter was R$2.1 billion, with an average term of 11 days. The prepayment of receivables is an operation typical to the retail sector and the Brazilian market and a relevant component of the Company's treasury management, which manages the cash balance invested and the amount of receivables available for discount.

The Company's cash and cash equivalents, which consider the cash at the end of the period and the receivables not discounted, evolve together with the average cash invested, which reached R$ 1,764 billion in 2Q25. For comparison, the average cash was R$ 835 million in 2Q24, R$ 1,325 billion in 3Q24, R$ 1,917 billion in 4Q24, and R$ 1,845 billion in 1Q25. It is worth noting that the available cash position in 2Q24 was higher mainly because of the inflow of R$ 1.8 billion from the issuance of debentures at the end of June 2024. These funds were used to pay maturities of an equivalent amount in 3Q24. 5 2Q2 2 5 5 Q2 2 Q2 2 5 Q252 2 2Q25 5 5 as s o te e e a les s o te e e a les e e a les ot s o te a la le as os o 5 5 5 12 ADVANCES IN ESG Assaí continues promoting prosperity for everyone, from sunup to sundown, through a robust and effective sustainability strategy, ensuring that our growth creates value for both society and the environment.
