EXTERNAL ASSURANCE

Opinion
We have audited the consolidated financial statements of Grupo Comercial Chedraui, S. A. B. de C. V. and Subsidiaries (the Entity) which include the consolidated statements of financial position as of December 31, 2020 and 2019, the related consolidated statements of profit or loss and other comprehensive income, changes in stockholders’ equity and cash flows for the years then ended December 31, 2020 and 2019, as well as the explanatory notes to the consolidated financial statements, which include a summary of the significant accounting policies applied.

In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Entity as of December 31, 2020 and 2019, as well as their financial performance and their cash flows for the years then ended, in conformity with International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board.

Bases for the opinion
We have performed our audits in conformity with International Auditing Standards (IAS). Our responsibilities under these standards are explained more extensively in the section Auditors’ responsibilities in relation to the audit of the consolidated financial statements of our report. We are independent from the Entity in conformity with the Code of Ethics of the International Ethics Standards Board for Accountants (IESBA Code of Ethics) and that issued by the Mexican Institute of Public Accountants (IMCP Code of Ethics), and we have complied with the other ethical responsibilities in conformity with the IESBA Code of Ethics and the IMCP Code of Ethics. We believe that the audit evidence obtained provides a sufficient and adequate basis for our opinion.

Key audit matters
The key audit matters are those matters which, in our professional judgment, have been most important in our audit of the consolidated financial statements for the current period. These matters have been dealt with in the context of our audit of the consolidated financial statements taken as a whole and in the formation of our opinion on the latter, and we do not issue a separate opinion on these matters. We have determined that the matters described below are the key audit matters which should be communicated in our report.

Investment properties
To determine the fair value of the investment properties in accordance with International Accounting Standard 40 (“IAS 40”), certain judgments were used by management. There is a risk that the determination of the assumptions used by management to calculate future cash flows may not be reasonable based on current and future foreseeable conditions.

Our audit procedures to cover this risk included the following:
Control and substantive testing over the financial projections that were used to determine the fair value of the investment properties, for which we tested the reasonability of the revenues and expenses used to determine the discounted future cash flows, also, we tested the arithmetical accuracy of the projections, and evaluated

the assumptions used by the Entity to determine them, and confirmed, based on our knowledge of the Entity and the audited historical information, that any nonrecurring effect will be normalized so that such effects will not be considered in the financial projections. Additionally, we evaluated the reasonableness of the discount rate used, for which purpose we involved our financial advisory specialists. The results of our audit procedures were reasonable.

Notes 3 and 11 to the consolidated financial statements include the Entity’s disclosures regarding investment properties.

Impairment of long-lived assets
The Entity has identified that the minimum cash generating units are the stores, for which an analysis is performed as required by International Auditing Standard 36 (“IAS 36”), in which the value in use, either using discounted future cash flows or fair value calculations, is calculated to determine if the carrying amount of the assets is impaired. There is a risk that the determination of the assumptions used by management to calculate future cash flows, as well as the appraisal value determined by the independent expert, may not be reasonable based on current and future foreseeable conditions.

Our audit procedures to test the risk in relation to the impairment of long-lived assets included:
Control and substantive testing where we detail tested the projected income and expenses, and based on discounted cash flows; we further verified, based on our knowledge of the Entity and the audited historical information, that any nonrecurring effect will be normalized in the financial projections. We also evaluated the reasonableness of the discount rate used, for which purpose we involved our financial advisory specialists. The results of our audit procedures were reasonable.

Information other than the Financial Statements and Auditor’s Report
Management is responsible for the other information. The other information comprises two documents, the Entity's Annual Report and the information that will be incorporated in the Annual Report which the Entity is required to prepare in accordance with article 33 Fraction I, subsection b) of the fourth title, first chapter of the General Provisions Applicable to Issuers of Securities and Other Participants in the Securities Market in Mexico (the requirements). As of the date of our auditor’s report, we have not yet obtained these documents and they will be available only after the issuance of this Audit Report.

Our opinion of the consolidated financial statements does not cover the other information and we do not express any form of security about it.

Other Matter
The accompanying consolidated financial statements have been translated into English for the convenience of readers.

In connection with our audit of the consolidated financial statements, our responsibility is to read the other information and, in doing so, consider whether if the other information is materially inconsistent with the consolidated financial statements or our knowledge obtained during the audit or otherwise appears to be materially misstated. When we read the Annual Report we will issue the auditors’ legend about the reading thereof, required in Article 33 Fraction I, subsection b) numeral 1.2. of the Provisions or if we conclude that it is materially misstated we would be required to report this fact.

Responsibilities of Management and those charged with governance for the consolidated financial statements
Management is responsible for the preparation and reasonable presentation of the accompanying consolidated financial statements in conformity with the IFRS, and for any internal control that management believes necessary to enable the preparation of the consolidated financial statements free from material misstatement due to fraud or error.

In preparing the consolidated financial statements, management is responsible for assessing the Entity’s ability to continue as a going concern, disclosing,

as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Entity or to cease operations, or has no realistic alternative but to do so.

Those charged with governance are responsible for overseeing the Entity’s financial reporting process.

Auditor’s responsibilities in relation to the audit of the consolidated financial statements
Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these consolidated financial statements.

As part of an audit in accordance with IASs, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

- ­ Identify and evaluate the risks of material misstatements in the consolidated financial statements, due to fraud or error, by designing and applying audit procedures which respond to these risks, and by obtaining audit evidence which is sufficient and appropriate to provide the basis for our opinion. The risk of not detecting material misstatements resulting from fraud is greater than those resulting from an error, because fraud may involve collusion, forgery, deliberate omissions, intentionally erroneous declarations or the evasion of internal control.
- ­ Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control.
- ­ Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.
- ­ Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Company to cease to continue as a going concern.
- ­ Evaluate the overall presentation, structure and content of the financial statements, including the disclosures, and whether the financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

- We obtained sufficient and adequate audit evidence related to the financial information of the entities and business activities which comprise the Entity in order to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision and performance of the audit of the entities comprising the Entity. We are the only persons responsible for our audit opinion.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.
