MESSAGE FROM THE CHAIRMAN AND CEO

Dear Investors,

We delivered a strong start to 2026. In the first quarter, we opened 123 net new stores, bringing our total store base to 3,469 units. Despite a soft consumer environment in Mexico, we achieved same-store sales (SSS) growth of 16.0% in 1Q26, underscoring the strength of our value proposition and increasing customer loyalty.

We remain among the fastest-growing retailers globally. Total revenue for 1Q26 reached Ps. 22,860 million, an increase of 33.4% versus 1Q25, driven by robust SSS growth and the continued expansion of our store network.

EBITDA, excluding the impact of the non-cash share-based payment, was Ps. 1,276 million, up 38.9% year-over-year. Reported EBITDA was Ps. 554 million and includes the effect of this non-cash share-based payment.

While EBITDA margin is an important indicator that we expect will continue to improve over time, we do not manage the business to meet a specific quarterly margin target. Instead, we focus on execution: opening successful stores, continuously enhancing value for our customers, and improving operational efficiency. This we believe creates long-term shareholder value and sustains our competitive advantages.

We maintain a focus on cash generation. Our business generates cash both from operations and from structurally negative working capital, driven by strong sales growth, healthy margins, stable payables, and rapid inventory turnover.

Our business model continues to be robust, resilient, and highly scalable. As we grow, we remain committed to getting the fundamentals right: delivering outstanding value to customers, maintaining disciplined execution, and driving ongoing productivity and efficiency gains.

We are encouraged by our momentum heading into the rest of the year and remain confident in our ability to continue delivering long-term value for our customers, employees, and shareholders.

Thank you for your continued trust and support.

K. Anthony Hatoum, Chairman and Chief Executive Officer

FINANCIAL RESULTS

TOTAL REVENUE

Total revenue for 1Q26 was Ps. 22,860 million, up 33.4% year-over-year. Most of this growth was driven by sales from stores that have been operating for more than one year, and, to a lesser extent, the incremental sales from 580 net new stores opened in the past twelve months.

GROSS PROFIT AND GROSS PROFIT MARGIN

Gross profit for 1Q26 was Ps. 3,704 million, an increase of 35.0% compared to 1Q25. This increase reflected sales growth and a 19-bps expansion in gross margin. A better commercial margin offset increased logistic costs year-over-year associated with the opening of four distribution centers in the second half of 2025.

EXPENSES

Sales expenses primarily reflect the cost of operating our stores, including wages and energy. In 1Q26, sales expenses reached Ps. 2,364 million, a 34.1% increase compared to 1Q25. This growth was mainly driven by an increase in store opening and the associated increase in depreciation and amortization expenses, while most other expenses (including labor) grew at a slower pace than revenue. As a percentage of total revenue, sales expenses stood at 10.3% in 1Q26, an expansion of 5 bps year-over-year.

Administrative expenses refer to expenses not directly related to operating our stores, such as headquarters, regional office expenses, and share-based compensation. For 1Q26, administrative expenses totaled Ps. 1,379 million, a 95.5% increase compared to 1Q25. This increase reflected (i) higher non-cash share-based payment expense, including the recognition of the Liquidity Event Plan (LEP) disclosed in February 2024 and granted by the Board of Directors in June 2025, subject to a quarterly vesting schedule (see Appendix 2 of this Earnings Release for additional details); (ii) increased staffing expenses for the new regional operations; and (iii) continued investments in human capital. As a percentage of revenue, administrative expenses increased from 4.1% in 1Q25 to 6.0% in 1Q26. The non-cash share-based compensation is reflected in our fully diluted share count.

Excluding non-cash share-based payment expense, administrative expenses for 1Q26 amounted to Ps. 658 million, an increase of 33.6% compared to 1Q25. As a percentage of revenue, administrative expenses excluding non-cash share-based payment expense stood at 2.9% in 1Q26, unchanged from 1Q25.

Please refer to Appendix 2 of this Earnings Release for an updated table summarizing the share-based payment expense plans and related expenses.

Other income - net, which includes, among other items, revenues from non-operative activities such as asset disposals, cost reimbursements, and insurance proceeds, amounted to a net income of Ps. 21 million in 1Q26, compared to a net income of Ps. 23 million in 1Q25. As a percentage of revenue, other income– net decreased by 4 bps year-over-year.

EBITDA AND EBITDA MARGIN

For 1Q26, EBITDA was Ps. 554 million, compared to Ps. 705 million in 1Q25. As previously described, our EBITDA was impacted by the increase in non-cash share-based payment expense.

Excluding non-cash share-based payment expense, EBITDA was Ps. 1,276 million, an increase of 38.9% compared to 1Q25. The EBITDA margin for 1Q26, adjusted to exclude the non-cash share-based compensation, increased by 22 bps to 5.6%.

Please see the last section of this release on how we calculate EBITDA and EBITDA Margin, which are non-IFRS financial measures.

ADDITIONAL DISCLOSURES

To allow investors to better assess our performance, the Company is providing the following supplementary information:

• Share-based payment expense (non-cash): Non-cash share-based payment expense totaled Ps. 722 million in 1Q26, compared to Ps. 213 million recorded in 1Q25.
  For additional details, please refer to Appendix 2 of this Earnings Release.

• Building lease payments: The Company leases all except one of its stores and all of its distribution centers. In accordance with IFRS 16, the Company’s lease expenses are capitalized, and are not considered operating expenses. Tiendas 3B’s capitalized lease payments for buildings were Ps. 534 million in 1Q26, compared to Ps. 397 million in 1Q25.

FINANCIAL COSTS AND NET LOSS/INCOME

Financial income totaled Ps. 36 million in 1Q26, down from Ps. 38 million in 1Q25. The decrease was primarily driven by lower interest rates and the negative impact from the stronger MXN versus the USD.

Financial costs were Ps. 457 million for 1Q26, a 43.6% increase compared to 1Q25. This increase was primarily driven by higher interest expense on lease liabilities, reflecting the continued expansion of our stores, distribution center network and equipment.

The Company recorded a foreign exchange gain of Ps. 16 million in 1Q26, driven by the appreciation of the U.S. dollar against the Mexican peso, which positively impacted in Mexican Peso terms the Company’s U.S. dollar-denominated cash position still held from the IPO.

Income tax expense reached Ps. 135 million in 1Q26 compared to Ps. 113 million in 1Q25.

As a result, our net loss for 1Q26 was Ps. 558 million, compared to a net loss of Ps. 87 million for 1Q25.

BALANCE SHEET AND LIQUIDITY

As of March 31, 2026, the Company reported local currency cash and cash equivalents of Ps. 1,344 million. In addition, as of March 31, 2026, the Company held $151 million in U.S. dollar-denominated short-term bank deposits. The Company applied an exchange rate of Ps. 18.07 to one U.S. dollar as of March 31, 2026.

Our business model continues to generate strong operating cash flow from our negative working capital cycle due to our growing sales and high inventory turnover relative to payment terms. This robust cash flow has enabled us to fund our growth initiatives, including the expansion of new stores and distribution centers internally.

The information provided below summarizes cash flow changes in 1Q26:

Net cash flows provided by operating activities increased to Ps. 1,961 million for 1Q26 from Ps. 1,195 million for 1Q25. Our net working capital continues to be driven by a favorable ratio of Inventory Days to Payable Days.

Net cash flows used in investing activities totaled Ps. 683 million for 1Q26, compared to Ps. 510 million in 1Q25.

Net cash flows used in financing activities were Ps. 1,362 million for 1Q26, compared to the cash flows used in 1Q25 of Ps. 566 million.

In 1Q26, we opened 123 net new stores compared to the 117 net new stores opened in 1Q25. In the last twelve months, the Company opened net new 580 stores, compared to 507 stores in the twelve months ending 1Q25.

Same Store Sales grew by 16.0% for 1Q26, compared to 13.5% for 1Q25.

OTHER RECENT DEVELOPMENTS

Shareholders Meeting and Board Elections: On April 29, 2026, we held our Annual General Meeting of Shareholders, where K. Anthony Hatoum and Juan Pablo Cappello were re-elected as Class II directors of the Company. Our shareholders also elected Halil Erdogmus as a Class II director of the Company for the first time, in place of Alexis Meffre, who elected not to stand for re-election. We are thankful to Mr. Meffre for his service on our board during a transformational time for our Company.

Proceedings Against Payment Terminal Provider: As disclosed in our 4Q25 results, we recognized a one-time write-off of an account receivable relating to the termination of our payment terminal provider. We continue to pursue legal proceedings against the provider. These proceedings are subject to the general risks of litigation described in our annual report on Form 20-F filed with the U.S. Securities and Exchange Commission on April 2, 2026, including, among others, costs, counter legal actions, diversion of management time, adverse publicity or damage to our reputation and brand image, even if such actions are unfounded. Legal proceedings in Mexican courts may be protracted, and success on the merits is not assured.

Non-IFRS Measures and Other Calculations

For the convenience of investors, this release presents certain non-IFRS financial measures, which are not calculated in accordance with IFRS (“non-IFRS financial measures”). A non-IFRS financial measure is generally defined as one that purports to measure financial performance but excludes or includes amounts that would not be so excluded or included in the most comparable IFRS financial measure. Non-IFRS financial measures do not have standardized meanings and may not be directly comparable to similarly titled measures reported by other companies. These non-IFRS financial measures are used by our management for decision-making purposes and to assess our financial and operating performance, generate future operating plans and make strategic decisions regarding the allocation of capital. The non-IFRS financial measures presented herein have limitations as analytical tools, and you should not consider them in isolation or as substitutes for analysis of our results of operations presented in accordance with IFRS. Additionally, our calculations of non-IFRS financial measures may be different from the calculations used by other companies, including our competitors, and therefore, our non-IFRS financial measures may not be comparable to those of other companies.

We calculate “EBITDA”, a non-IFRS measure, as net profit (loss) for the period, plus income tax expense, financial costs, net, and total depreciation and amortization.

We calculate “EBITDA Margin”, a non-IFRS measure, for a period by dividing EBITDA for the corresponding period by total revenue for such period.

Same Store Sales: We measure “Same Store Sales” using revenue from sales of merchandise at stores that were operational for at least the full preceding 12 months for the periods under consideration. Stores that were temporarily closed (for one month or more) or permanently closed during the relevant measurement periods are excluded from this metric. Same Store Sales growth is calculated by comparing the Same Store Sales of stores that were opened and remained open throughout the relevant measurement period.

Lease Payments: Consistent with lease accounting required under IFRS 16, total depreciation and amortization includes the depreciation expense of right-of-use-asset corresponding to long-term leases, which is a non-cash expense. Such amounts, together with the interest expense on lease liabilities, is a proxy for but not equal to the Company’s actual cash expenditure incurred in connection with its leased properties.

Inventory Days: We calculate “Inventory Days” to be the average of beginning and end of period inventory balance, divided by cost of sales for the period and multiplied by the number of days during the period. Inventory Days measures the average number of days we keep inventory on hand before selling the product. This operating metric allows us to track our inventory management policies and observe how quickly we are able to rotate inventory, which is key to our cash conversion cycle.

Payable Days: We calculate “Payable Days” to be the sum of the average of beginning and end of period balance of suppliers and of accounts payable and accrued expenses, divided by cost of sales for the period and multiplied by the number of days during the period. Payable Days measures the average number of days that it takes us to pay suppliers after receiving goods or services. This metric allows us to track the terms of payment policies with suppliers and our ability to finance our operations through agreements with our suppliers.

APPENDIX 1: FULLY DILUTED SHARES ILLUSTRATIVE CALCULATION

To further improve investor’s understanding of our capital structure, we are providing below an illustrative calculation of our fully diluted share count as of March 31, 2026, inclusive of Class A common shares and Class C common shares subject to vested and unvested stock options, restricted stock units, and Class C common shares under the Liquidity Event Plan and the Bolton Partners Share Allocation. We calculate our fully diluted common shares outstanding by assuming the “net settlement” of all our outstanding options at their weighted average strike price.

The illustrative example below assumes:

• Price per Class A common share: US$35.00
• Weighted average exercise price of US$5.74 per Class C common share subject to options granted under our Legacy Plan
• Weighted average exercise price of $32.90 per Class A common share subject to options granted under our Post-IPO Equity Incentive Plan
• All outstanding options are vested as of the date hereof, for illustrative purposes only

The example above is provided for illustrative purposes only. The number of common shares outstanding would change if the strike price of the specific option being exercised were higher or lower than the weighted average strike price assumed for this exercise and/or if the market price for our Class A common shares was higher or lower at the time of exercise than the assumed price.

APPENDIX 2: SHARE-BASED PAYMENT EXPENSE

The tables and explanatory text below provide a breakdown of the expenses associated with stock options and restricted shares granted under the Legacy Plan, the Post-IPO Equity Incentive Plan, and the Liquidity Event Plan.

All our share-based compensation plans were previously fully disclosed in our offering documents and public filings, including in our annual report on Form 20-F for the year ended December 31, 2025, for the year ended December 31, 2024 and for the year ended December 31, 2023 filed with the U.S. Securities Exchange Commission (the “SEC”), each of which is available on the SEC’s website (www.sec.gov) and on our investor relations website.

The previously disclosed Liquidity Event Plan in the aggregate amount of 7.5 million Class C common shares was subject to formal assignment and delivery. On June 24, 2025, Tiendas 3B formally granted the 7.5 million Class C common shares to the Liquidity Event Plan participants. Our board of directors also determined it was in the best interest of the Company primarily in relation to talent retention to subject the award to quarterly vesting over a three-year period. The corresponding expense will be recognized during such three-year period beginning in the third quarter of 2025 using a graded vesting model (accelerated expense recognition) with a corresponding increase to equity.

Under IFRS, the cost of this award is recognized as a non-cash expense in the profit and loss statement, even though the award is equity-settled. The fair value of the grant is determined at the grant date, and for awards with vesting conditions, the expense is recognized over the applicable vesting period. To improve investors’ understanding of how we recognize the non-cash expenses associated with each of our share-based payment arrangements, we are including below our current expectations for non-cash share-based payment expenses per program from 2025 until 2028. We note however, that these figures may vary slightly from initial estimates due to the actual vesting of the awards.

It is important to note that the formal grant of these awards and vesting schedule does not result in any additional dilution beyond what was previously disclosed and is already reflected in our fully diluted share count, discussed in Appendix 1. Additionally, the estimated share-based payment expense reflected in the table below only considers awards granted as of today. The Company may grant additional awards under the 2024 Equity Incentive Plan as administered by the Company’s compensation committee (or such other committee of our board of directors to which it has properly delegated power, or if no such committee or subcommittee exists, our board of directors).
