INDEPENDENT AUDITOR’S REPORT
To the Shareholder’s Meeting and the Supervisory Board of Bank Millennium S.A.
Report on the Audit of the Annual Consolidated Financial Statements
Opinion
We have audited the annual consolidated financial statements of the group (the “Group”) with Bank Millennium S.A. as the parent (the “Parent”, “Bank”), which comprise the consolidated balance sheet as at December 31, 2023, and the consolidated income statement, consolidated statement of  total comprehensive income, consolidated statement of changes in equity and consolidated cash flow statement for the year then ended, and notes to the consolidated financial statements, including a summary of significant accounting policies and other explanatory information (the “consolidated financial statements”).
In our opinion, the accompanying consolidated financial statements:
give a true and fair view of the economic and financial position of the Group as at December 31, 2023, and of its financial performance and its cash flows for the year then ended in accordance with the applicable International Financial Reporting Standards, as endorsed by the European Union, and the adopted accounting policies;
comply, as regards their form and content, with the applicable laws and the articles of association of the Parent.
Our opinion is consistent with the Additional Report to the Audit Committee which we issued on date of this report.
Basis for Opinion
We conducted our audit in accordance with the Polish Standards on Auditing (“PSAs”) in the wording of the International Standards on Auditing adopted by the National Council of Statutory Auditors and in compliance with the Act on Statutory Auditors, Audit Firms and Public Oversight of 11 May 2017 (the “Act on Statutory Auditors”, Journal of Laws of 2023, item 1015, as amended) as well as Regulation (EU) No 537/2014 of the European Parliament and of the Council of 16 April 2014 on specific requirements regarding statutory audit of public-interest entities (“EU Regulation”, Official Journal of the European Union L158, as amended). Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements section of our report.
We are independent of the Group in accordance with the principles of professional ethics specified in the International Code of Ethics for Professional Accountants (including International Independence Standards) (“Code of ethics”) developed and issued by the International Ethics Standards Board for Accountants and adopted by the National Council of Statutory Auditors, together with the ethical requirements that are relevant to the audit of the financial statements in Poland, and we have fulfilled our other ethical responsibilities in accordance with these requirements and the Code of ethics. Throughout the audit, both the key statutory auditor and the audit firm remained independent of the Group in accordance with the independence requirements set out in the Act on Statutory Auditors and in the EU Regulation.
We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.
Other Matter
The Group’s consolidated financial statements for the year ended December 31, 2022 were audited by another auditor who expressed an unqualified opinion on those financial statements on February 15, 2023.
Key Audit Matters
Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the consolidated financial statements of the current period. They encompass the most significant assessed risks of material misstatement, including assessed risks of material misstatement due to fraud. These matters were addressed in the context of our audit of the consolidated financial statements as a whole, and in forming our opinion thereon. We summarized our response to those risks and, where appropriate, we presented the key findings related to those risks. We do not provide a separate opinion on these matters.
Key audit matter
How we addressed the matter
Provisions for litigations concerning the portfolio of mortgage loans indexed to Swiss franc (CHF)
The Parent granted foreign currency mortgage loans indexed to CHF (“CHF loans”). As it is presented in the Note 14.22 to the consolidated financial statement Loans and advances to customers financial statement Loans and advances to customers in point 22j Loans and advances to customers measured in amortized cost by foreign currency structure the carrying amount of CHF loans deducted by the change in expected cash flows resulting from legal risk as of 31 December 2023 amounted to PLN 3 121 979 thousands.
As it is described in the Note 13.1 to the consolidated financial statements Court claims and current provisions on legal risk, the Parent is a defendant in numerous legal cases which include claims regarding the partial invalidity of the credit agreements, i.e. in terms of indexation provisions or a ruling that the agreements are fully invalid.
Management's judgments regarding the recognition and measurement of provisions for lawsuits and legal risk are inherently burdened with risk and may change over time due to the fact that the estimated results of the current cases depend on future court ruling.
The judgement of the Court of Justice of the European Union (CJEU) from 3 October 2019 regarding CHF loans increases the uncertainty of estimates related to recognition of provisions.
The case law of the CJEU interpreted the causes and effects of the invalidity of foreign currency mortgage loan agreements. Further judicial practice of Polish courts will play an important role in fulfilling the content of the Tribunal's instructions, and, moreover, this practice will be of significant importance as to issues which, considering the scope of the CJEU's competences, are subject to national jurisprudence.
Due to the materiality of the CHF loan portfolio, as well as the significant role and complexity of the Management Board's judgments and estimates regarding provisions for the current and potential claims and the proposed settlements, the recognition and the valuation of the mentioned provision was considered as the key audit matter.
As part of the audit procedures, we familiarized ourselves and assessed the accounting policy used by the Group to account for the costs of legal risk of CHF loans.
Our audit procedures also included understanding of the process for establishing provision for the CHF loan lawsuits and assessing the design and implementation of controls in relation to the model used to estimate this provision.
With respect to the model used to estimate provision our procedures included, among the others:
  • assessment of the methodology of estimating provisions in relation to the legal proceedings and proposed settlements related to CHF loans and the analysis of the rationality and validity of the adopted assumptions, including especially:
  • - the probability of occurrence of the particular types of verdicts for pending legal cases;
  • - the estimated amount of losses in the event of the each type of verdict and the proposed settlements;
  • - the estimated inflow of new individual claims and estimated number of settlements and their distribution over the time;
  • based on random sample verification of accuracy of the underlying data used in calculation;
  • verification of mathematical accuracy of the calculation;
  • assessment of the adequacy and the completeness of provisions for the legal cases recognized by the Group with regard to the existing legal documentation, and analysis of the provision sensitivity to the changes in the most important assumptions.
Moreover with our legal specialists we performed review of the current and expected jurisdiction in case of CHF loans claims.
We analyzed of the significant data after the balance sheet date in relation to the assumptions adopted by the Group as at the balance sheet date.
Our procedures included also analysis of the accuracy and completeness of disclosures in the consolidated financial statements in accordance with applicable reporting standards.
Impairment of loans and advanced granted to customers
Detailed information on the methods and models applied by the Group and the level of impairment losses on loans and advances to customers is presented in point 7.3 Adopted accounting principles, point 8.3 Credit risk and Note 14.22 Loans and advances to customers in the consolidated financial statements.
As presented in note 14.22 to consolidated financial statement Loans and advances to customers point 22g. Change in impairment losses on loans and advances measured in amortized cost amount of impairment losses as of December, 31, 2023 is PLN 2 496 554 thousand.
Estimation of impairment allowance requires a significant judgement of the Parent's Management Board and adoption in the process of calculation, significant macroeconomic assumptions, especially with regard to the estimation of credit risk parameters in models of expected credit losses calculation in accordance with the requirements of the International Financial Reporting Standard 9 “Financial Instruments” (IFRS 9).
We considered matter by the key audit matter due to the significant impact of impairment allowances on valuation of credit receivables.
We critically analyzed the design and implementation of the process and policy of recognition of the impairment allowances on credit exposures and we assessed the control system in this process, including automated controls in the Group's IT systems, considering also possible override of controls.
Our audit procedures included reconciliation of the loan database Group’s general ledger to confirm the completeness of the recognition of credit receivables that are the basis for impairment losses calculation, as well as the value of these impairment allowances on loans.
In relation to the verification of the correct application of the requirements of IFRS 9, our procedures included, among the others:
  • assessment of the methodology applied by the Group with respect to the classification and valuation of financial assets in terms of their compliance with the requirements of IFRS 9 and with the market practice;
  • evaluation of the Group's impairment methodology from the perspective of compliance with the requirements of IFRS 9, in particular as regards the application of SICR criteria, which means a significant increase in credit risk from the moment of granting a loan, for a selected sample of loan exposures, definition of default, adopted PD and LGD parameters and taking into account prospective information in the calculation of expected credit losses;
  • assessment of the completeness and correctness of the disclosures, especially as regards the credit risk of financial assets.
For the collectively assessed loans, we performed, among others, the following procedures:
  • analysis of the applied methodology of estimating allowances for expected credit losses, including adequacy of risk parameters used by the Group;
  • independent recalculation of the expected credit loss for randomly selected exposures and chosen parameters in the portfolio approach;
  • evaluation of changes in the assumptions made for the construction of models used for the measurement of credit risk and the applied approach to the verification of models based on historical data (so-called back-tests).
In relation to the impairment estimated on the basis of the individual method we performed the following procedures:
  • analysis of the correctness of the process of identifying the triggers for impairment;
  • evaluation of the correctness of the estimation of allowance for the selected sample of the credit exposures with identified indicators of the impairment in terms of the correctness of the assumed values of collaterals and assumptions concerning other cash flows.
Our procedures also included analysis of disclosures in the financial statements in terms of their completeness and adequacy in accordance with applicable reporting standards.
Result on bancassurance transaction
As disclosed in Note 14.5 Result on the derecognition of financial assets and liabilities not measured at fair value through profit or loss of the consolidated financial statements, in 2023 the Bank entered into an agreement for the sale of 80% of shares in Millennium Financial Services sp. z o.o. (the “Company”) to Towarzystwo Ubezpieczeń na Życie Europa S.A., which acquired 72% of the Company's shares and Towarzystwo Ubezpieczeń Europa S.A., which acquired 8%of the Company's shares (collectively, the “Buyers”). The Bank also entered into agreements with the Buyers and the Company concerning the exclusive insurance distribution model, including cooperation agreements, distribution agreements and agency agreements. The strategic insurance cooperation provides long-term (10 years) cooperation in the field of bancassurance with respect to specific insurances related to credit products offered by the Bank.
In connection with the sale of the Company's shares, in 2023 the Group recognized in the consolidated profit and loss account a result in the total amount of PLN 652.4 million.
Due to the significance of the result recognized on the transaction and the fact that the accounting treatment of the individual agreements comprising the transaction contains a significant level of professional judgment, we consider this area to be a key audit matter. 
As part of the audit procedures, we reviewed the agreements concluded with the Buyers and the Company.
With respect to bancassurance transactions, we analysed the correctness of recognition the transaction in the light of International Financial Reporting Standards, including among others:
  • we assessed the accounting policy adopted by the Group for the purposes of accounting for the transaction;
  • we analysed in detail the fulfilment of the conditions for the loss of control over the Company;
  • we assessed the completeness of the Group's identification of performance obligations and the principles of allocating remuneration to the identified components of performance obligations;
  • we analysed the remaining agreements concluded with the Buyers and the Company in terms of identifying contractual obligations and the correctness of assigning performance remuneration to them.
In relation to the recognition and classification in the Group’s financial statements the remaining 20% of shares in the Company:
  • we assessed the correctness of the classification and valuation rules adopted;
  • with the support of our internal valuation specialists, we analysed the valuation of 20% of the Company's shares remaining in Group, including a critical analysis of selected assumptions.
Our procedures also included an analysis of disclosures in the financial statements in terms of their completeness and adequacy in accordance with applicable reporting standards.
Assessment of the going concern assumption
As described in Section 7.1 Statement of Compliance with International Financial Reporting Standards Statement of the consolidated financial statements, the financial statements have been prepared using the going concern assumption, which means that the Bank's operations continue to be a going concern for at least 12 months from the date of preparation of the financial statements.
The government’s programme to help borrowers introduced in 2022, which covered the years 2022 and 2023, resulted in the need to launch the Recovery Plan and the Capital Protection Plan, which were still implemented by the Bank in 2023. Based on the activities carried out by the Bank under the Plans, the capital ratios as of 31 December 2023 were above the minimum requirements.
Due to the fact that the Bank continues to implement the Capital Protection Plan and Recovery Plan, we consider this area to be a key audit matter
In response to the Bank's implementation of the Recovery Plan and the Capital Protection Plan we performed:
  • analysis of the Recovery Plan and the Capital Protection Plan;
  • discussion with the Bank's Management Board on plans and actions to be taken to ensure the continuation of the Bank's operations and the implementation of the Bank Recovery Plan and Capital Protection Plan;
  • assessment of the Bank's ability to implement the above plans;
  • discussion with the Bank's Management Board and analysis of scenarios of the potential impact of future uncertainties, including the risk related to the possible extension of the so-called credit holidays and further development of court jurisdiction in the field of FX mortgage loans;
  • review of capital adequacy ratios with a sensitivity analysis in the event of negative scenarios;
  • review of the Bank's liquidity position;
  • review of protocols and correspondence with the regulator in this respect;
  • analysis of disclosures in the financial statements concerning the Bank's going concern assumptions.
Responsibilities of the Management Board and the Supervisory Board of the Parent for the Consolidated Financial Statements
The Parent’s Management Board is responsible for the preparation of consolidated financial statements which give a true and fair view of the economic and financial position of the Group and of its financial performance in accordance with the applicable International Financial Reporting Standards, as endorsed by the European Union, the adopted accounting policies as well as the applicable laws and articles of association of the Parent, and for such internal control as the Parent’s Management Board determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.
In preparing the consolidated financial statements, the Parent’s Management Board is responsible for assessing the Group’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 the Parent’s Management Board either intends to liquidate the Group or to cease operations, or has no realistic alternative but to do so.
The Management Board and members of the Supervisory Board of the Parent are obliged to ensure that the consolidated financial statements meet the requirements of the Accounting Act of 29 September 1994 (the “Accounting Act”, Journal of Laws of 2023, item 120 as amended). Members of the Parent’s Supervisory Board are responsible for overseeing the financial reporting process.

Auditor’s Responsibilities for 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 PSAs 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.
The scope of an audit does not include an assurance about the future profitability of the Group or the effectiveness or efficiency of the Parent’s Management Board in managing the Group’s affairs at present or in the future.
As part of an audit in accordance with PSAs, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:
  • identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override 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 Group’s internal control;
  • evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the Parent’s Management Board;
  • conclude on the appropriateness of the Parent’s Management Board’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 Group’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 consolidated 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 Group to cease to continue as a going concern;
  • evaluate the overall presentation, structure and content of the consolidated financial statements, including the disclosures, and whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation;
  • obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Group to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision and performance of the Group audit. We remain solely responsible for our audit opinion.
We communicate with the Parent’s Supervisory Board 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 the Parent’s Supervisory Board with a statement that we have complied with relevant ethical requirements regarding independence, and that we will communicate with it all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, actions taken to eliminate threats or safeguards applied.
From the matters communicated with the Parent’s Supervisory Board, we determined those matters that were of most significance in the audit of the consolidated 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.

Report on Other Legal and Regulatory Requirements
Opinion on the compliance of tags in consolidated financial statements prepared in the single electronic reporting format with the requirements of the regulation setting out technical standards on the specification of a single electronic reporting format
Scope of the Engagement
With regard to the audit of the consolidated financial statements we have performed a reasonable assurance engagement to evaluate whether or not the Group’s consolidated financial statements for the year ended 31 December 2023, prepared in the European Single Electronic Format and included in the file named grupamillennium-2022-12-31-pl.zip (“consolidated ESEF financial statements”) were tagged in compliance with the requirements of Commission Delegated Regulation (EU) 2019/815 of 17 December 2018 supplementing Directive 2004/109/EC of the European Parliament and of the Council with regard to regulatory technical standards on the specification of a single electronic reporting format (“ESEF Regulation”).
Identification of applicable Criteria
The consolidated ESEF financial statements were prepared by the Management Board of the _Parent in order to satisfy the tagging and technical requirements regarding the single electronic format specification, as determined in the ESEF Regulation.
The scope of our assurance service includes checking compliance of the tagging used in the consolidated ESEF financial statements with the requirements of the ESEF Regulation which, in our view, constitute appropriate criteria for us to express an opinion.
Scope of Responsibility of the Management Board and the Supervisory Board of the Parent
The Management Board of the Parent is responsible for the preparation of the consolidated ESEF financial statements in line with the tagging requirements and with the technical requirements related to the specification of the single electronic format as determined in the ESEF Regulation. This responsibility includes the selection and application of appropriate XBRL tags, using the taxonomy set out in ESEF Regulation.
The Management Board of the Parent is also responsible for the design, implementation and maintenance of internal controls to enable the preparation of consolidated ESEF financial statements that are free from material non-compliance with the requirements of ESEF Regulation.
Members of the Supervisory Board of the Parent are responsible for overseeing the financial reporting process, which also involves the preparation of financial statements in the format determined by applicable law.
Scope of our responsibility
Our objective was to express, based on a reasonable assurance engagement, an opinion whether the Group’s consolidated financial statements for the year ended 31 December 2023 were tagged in compliance with the requirements of ESEF Regulation.
The service was provided by us in compliance with the Polish Standard on Assurance Services Other than Audits or Reviews 3001PL - Audit of Financial Statements Prepared in the Single Electronic Format (“PSAE 3001PL”) and, where applicable, with the Polish Standard on Assurance Services Other than Audits or Reviews 3000 (Revised) in the wording of the International Standard on Assurance Services Other than Audits or Reviews of Historical Financial Information (amended) (“PSAE 3000 (Revised)”).
The Standard requires that we plan and perform the procedures so as to obtain reasonable assurance that the consolidated ESEF financial statements were prepared in compliance with the determined criteria.
Reasonable assurance is a high level of assurance, but is not a guarantee that an engagement conducted in accordance with PSAE 3001PL and, where applicable, with PSAE 3000 (Revised) will always detect a material misstatement when it exists.

The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation of the consolidated ESEF financial statements, in order to design procedures that are appropriate in the circumstances to enable the auditor to obtain sufficient appropriate evidence. The purpose of the assessment of the internal control system’s operation was not to express an opinion on its effectiveness.
Our quality management
Our firm applies the Polish Standard on Quality Control 1 in the wording of the International Standard on Quality Management (PL) 1 – “Quality Management for Firms that Perform Audits or Reviews of Financial Statements, or Other Assurance or Related Services Engagements” adopted on 15 November 2022 by Resolution No. 38/I/2022 of the Council of the Polish Agency for Audit Oversight, which requires the firm to design, implement and operate a quality management system, including policies or procedures regarding compliance with ethical requirements, professional standards and applicable legal and regulatory requirements.
Our independence
We have complied with the independence and other ethical requirements specified in the International Code of Ethics for Professional Accountants (including International Independence Standards) issued by the International Ethics Standards Board for Accountants and adopted by the National Council of Statutory Auditors based on the basic principles of integrity, objectivity, professional competence and due care, confidentiality and professional behaviour.
Summary of the work performed
The procedures we planned and carried out included, among others:
  • gaining an understanding of the process of the Company’s preparing the consolidated ESEF financial statements, which comprised the selection and application of XBRL tags as well as ensuring compliance with ESEF Regulation, including an understanding of the internal controls relevant to this process;
  • reconciling the tagged information included in the consolidated ESEF financial statements with the audited consolidated financial statements (using a selected sample);
  • using a specialized IT tool, assessing the fulfilment of technical standards on the specification of the single electronic reporting format, and the completeness of XBRL tagging in the consolidated ESEF financial statements;
  • evaluation of whether the XBRL tags from the taxonomy set out in ESEF Regulation were applied properly and whether extension taxonomy elements were used in the event that the relevant elements were not identified in the core taxonomy set out in ESEF Regulation;
  • evaluation of the correctness of anchoring of the extension taxonomy elements used to the core taxonomy set out in ESEF Regulation.
We believe the obtained evidence constitutes a sufficient and appropriate basis for us to express an opinion on the compliance of tagging with ESEF Regulation.
Opinion on the Compliance with Requirements of ESEF Regulation
The issues described above provide the basis for auditor’s opinion, therefore, they should be considered by readers of the opinion.
In our opinion, the indicated consolidated ESEF financial statements have been tagged, in all material respects, in compliance with requirements of ESEF Regulation.

Information on the compliance with the binding prudence principles
The Management Board of the Parent Company is responsible for ensuring compliance of the Group's activities with the prudential regulations resulting from the provisions of separate regulations, in particular for correct determination of capital ratios.
Our obligation is to inform in the audit report whether the Group complies with the applicable prudential regulations specified in separate regulations, in particular whether the Group correctly determined the capital ratios presented in point 8.2 of the consolidated financial statements Capital management.
The purpose of the audit of the consolidated financial statements was not to express an opinion on the Group's compliance with applicable prudential regulations, and therefore we do not express an opinion on this matter.
