• have been prepared on the basis of properly maintained books of account in accordance with the provisions of Chapter 2 of the Accounting Law of 29 September 1994 (the “Accounting Act”).

Our opinion is consistent with our additional report to the Audit Committee issued on the date of this report.

What we have audited

We have audited the annual separate financial statements of Powszechna Kasa Oszczędności Bank Polski S.A. which comprise:

• the separate statement of financial position as at 31 December 2022;

and the following prepared for the financial year from 1 January to 31 December 2022:

• the separate income statement;

• the separate statement of comprehensive income;

• the separate statement of changes in equity;

• the separate statement of cash flows, and

• the notes comprising a description of the significant adopted accounting policies and other explanations.

Basis for opinion

We conducted our audit in accordance with the National Standards on Auditing in the wording of the International Standards on Auditing as adopted by the resolution of the National Council of Statutory Auditors (“NSA”) and pursuant to the Law of 11 May 2017 on Registered Auditors, Registered Audit

2

Companies and Public Oversight (the “Law on Registered Auditors”) and the Regulation (EU) No. 537/2014 of 16 April 2014 on specific requirements regarding the statutory audit of public-interest entities (the “EU Regulation” ) . Our responsibilities under NSA are further described in the Auditor’s responsibilities for the audit of the separate financial statements section of our report.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Independence

We are independent of the Bank in accordance with the International Code of Ethics for Professional Accountants (including International Independence Standards) issued by the International Ethics Standards Board for Accountants (IESBA Code) as adopted by resolution of the National Council of Statutory Auditors and other ethical requirements that are relevant to our audit of the separate financial statements in Poland. We have fulfilled our other ethical responsibilities in accordance with these requirements and the IESBA Code. During the audit, the key registered auditor and the registered audit firm remained independent of the Bank in accordance with the independence requirements set out in the Law on Registered Auditors and in the EU Regulation.

Our audit approach

Overview

• The overall materiality threshold adopted for the purposes of our audit was set at PLN 341 million. We adopted overall materiality based on the value of 5% of the profit before tax adjusted for tax on financial institutions and the loss resulting from changes in expected cash flows from mortgage loans resulting from the entry into force of the act enabling customers to defer repayment of selected principal and interest instalments (“credit moratoria”). For reasons of prudence, we have adjusted the overall materiality so that it does not exceed 1% of the B ank 's net assets .

• We have audited the annual financial statement of the B ank for the period ended 31 December 2022.

• Estimating the cost of legal risk related to the portfolio of mortgage loans in Swiss francs ( CHF )

• Estimating the value of expected credit losses in the portfolio of loans and advances to customers

• Estimates of interest income on loans and advances measured at amortised cost, including estimates resulting from the introduction of the act enabling customers to use the credit moratori a

Materiality

Bank scoping

Key audit matters

3

As part of designing our audit, we determined materiality and assessed the risks of material misstatement in the separate financial statements. In particular, we considered where the Bank’s Management Board made subjective judgements; for example, in respect of significant accounting estimates that involved making assumptions and considering future events that are inherently uncertain. As in all of our audits we also addressed the risk of management override of internal controls, including among other matters, consideration of whether there was evidence of bias that represented a risk of material misstatement due to fraud.

Materiality

The scope of our audit was influenced by our application of materiality. An audit is designed to obtain reasonable assurance whether the separate financial statements are free from material misstatement. Misstatements may arise due to fraud or error. They are considered material if, individually or in aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of the separate financial statements.

Based on our professional judgement, we determined certain quantitative thresholds for materiality, including the overall materiality for the separate financial statements as a whole , as set out in the table below. These, together with qualitative considerations, helped us to determine the scope of our audit and the nature, timing and extent of our audit procedures and to evaluate the effect of misstatements, if any, both individually and in aggregate on the separate financial statements as a whole.

Overall Bank materiality

341 mln PLN (2021: 348 mln PLN)

How we determined it

5% of the profit before tax adjusted for the tax on financial institutions and the loss resulting from the credit moratoria. For reasons of prudence, we adjusted the overall materiality so that it does not exceed 1% of the Bank's net assets.

Rationale for the materiality benchmark applied

We have adopted profit before tax as the basis for determining materiality because, in our opinion, it is an indicator commonly used by the users of financial statements to evaluate the Bank’s operations and it is a key benchmark.

We adjusted profit before tax by the tax on financial institutions, which has the nature of a special tax burden, and the loss resulting from the credit moratoria as a one-off event.

We adopted the materiality threshold of 5% because, based on our professional judgement, it is within the quantitative materiality thresholds acceptable for the auditing of profit-oriented entities in the financial sector.

We agreed with the Audit Committee of the Bank that we would report to them misstatements of the separate financial statements identified during our audit above 15 mln PLN, as well as misstatements below that amount that, in our view, warranted reporting for qualitative reasons.

Key audit matters

Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the separate financial statements of the current period. They include the most significant identified risks of material misstatements, including the identified risks of material misstatement resulting from fraud. These matters were addressed in the context of our audit of the separate financial statements as a whole, and in forming our opinion thereon. We do not provide a separate opinion on these matters.

Key audit matter

How our audit addressed the key audit matter

Estimating the costs of legal risk related to the portfolio of mortgage loans in S wiss francs (CHF)

As at the balance sheet date, the Bank had a portfolio of mortgage loans denominated in and indexed to CHF in the total amount of PLN 16,731 million before the adjustment to contractual cash flows due to the legal risk. As described in Note 25 Cost of legal risk of mortgage loans in convertible currencies to the separate financial statements, the contracts on the basis of which these loans were granted, contain clauses questioned by customers in courts due to abusiveness. At the moment, the jurisprudence of courts is not uniform, but a negative trend for banks is observed in relation to court judgments, which affects both the increase in the level of the estimated probability of unfavourable settlements of disputes and the increase in the number of court cases brought by the banks’ clients. Additionally, as described in Note 25, on 4 October 2021 the Bank’s Management Board launched a program of concluding voluntary settlements with customers, who have entered into loan agreements or mortgage-secured loans indexed to foreign currencies or denominated in foreign currencies. By 31 December 2022, 20,396 settlements were signed. Settlements concluded with customers result in the cancellation of the customers' debt under the CHF loan as if their loans from the beginning were loans in PLN at the WIBOR reference

As part of our audit, we assessed whether the accounting approach applied by the Bank complies with IFRS 9 and IAS 37. We focused on assessing the Bank’s approach to estimating the cost of legal risk of CHF mortgage loans, as well as the scope of disclosures included in the separate financial statements.

Our procedures were aimed mainly at a critical assessment of the model and individual assumptions adopted by the Bank’s Management that had a significant impact on the level of the gross book value adjustment of the portfolio and recognized provisions. In particular, we have carried out the procedures listed below:

● we assessed the design and implementation of monitoring and internal controls as part of legal risk management and in the process of estimating the adjustments to the gross book value of the portfolio and the provisions recognized;

● we interviewed the Bank’s Management and specialists involved in the estimation of the adjustments and provisions, including the Bank's lawyers and external experts, on the assumptions made based on historical observations, as well as information and events after the balance sheet date;

● in cooperation with our legal experts, we analysed the documentation and opinions of external law firms obtained by the Bank for the purposes of assessing the risk of considering clauses in the Bank’ agreements as abusive and the likelihood of the individual scenarios of possible outcomes of lawsuits;

rate increased by a negotiated margin based on the margin level used historically for such loans.

As at the balance sheet date, t he Bank estimated the costs to cover the above- mentioned legal risk, both for the active portfolio and for loans repaid before the balance sheet date, as well as for loan agreements currently questioned by clients in court. In the separate financial statements the Bank recognised these costs, for the active portfolio pursuant to paragraph B5.4.6 of IFRS 9 Financial Instruments (“IFRS 9”), by adjusting the gross carrying amount of the portfolio by reducing contractual cash flows from CHF- denominated or indexed mortgage loans, and for repaid loans by recognising provisions in accordance with the requirements of IAS 37 Provisions, Contingent Liabilities and Contingent Assets (“IAS 37”).

In 2022 due to settlements and court verdicts, the amount of PLN 1,478 million was settled against write-offs made in previous years and the estimated adjustment of the gross book value of this portfolio amounted to PLN 7,37 8 million and the recognised provisions amounted to PLN 94 5 million.

The costs of legal risk of mortgage loans in CHF were estimated using a statistical method that takes into account the impact of customer characteristics, as the sum of the products of:

● the likelihood of the client accepting the settlement and the amount of the Bank's loss under the settlement, and

● the probabilities of certain court settlements and the amount of loss for various scenarios of such settlements, taking into account the current and forecast number of court cases in the horizon in which the Bank is exposed to such risk.

Estimation of the costs of legal risk of mortgage loans in CHF is complex and requires a considerable degree of judgement with respect to the key assumptions:

● i n cooperation with our legal experts and statistical modelling experts, we analysed the documentation of the model;

● w e analysed the results of the backtest of the model for estimating the costs of legal risk of mortgage loans in CHF;

● substantive procedures:

o We analysed the results of settlements program by the Bank and how they were incorporated in the model;

o We obtained directly from the Bank’s external legal experts their assessment of the expected scenarios of the resolutions of court cases together with an assessment of the probability of these resolutions;

o We verified the method of calculating the value of potential losses for the scenarios assumed by the Bank;

o We checked the correctness and completeness of the input data being the basis for calculations in the Banks’ model (by performing tests of details on the completeness and accuracy of the input data);

o We verified the mathematical accuracy of the model calculation;

o We verified the correctness of the settlement with the clients;

o We verified the recognition of the settlement result in the books for the entire population .

We also verified adequacy and completeness of disclosures in the separate financial statements in accordance with applicable accounting standards, including disclosures in Note 78 S ubsequent events .

● the expected level of future settlements is based on the number of settlements concluded with clients so far and is characterised by a significant level of uncertainty due to the short observation period as well as changing external factors, which may affect future decisions of clients on joining the settlement program and affect future decisions of the Bank to continue with the settlements program ;

● the forecast number of future lawsuits is based on historical observations regarding court cases and is characterised by considerable uncertainty due to the high dynamics of the number of cases brought to court by the Bank's clients constituting the basis for estimation, as well as the uncertainty as to the forecast of clients' inclination to file a case in court in the future;

● the probabilities of resolutions in current and future court cases affecting the level of loss are subject to significant changes due to the lack of a uniform line of jurisprudence in previous court judgments ;

● the probabilities of recovering remuneration for the non-contractual use of capital in the case of cancel l ed loans, which is an integral part of the estimates of expected future cash flows from settlements of the CHF mortgage loan portfolio, is characterized by significant uncertainty in the light of the CJEU Advocate General's opinion of February 16, 2023, which questions the possibility of claiming remuneration for the non- contractual use of capital. As described in Note 78 Subsequent Events , despite the non-binding nature of this opinion, it may be a predictor of a negative judg e ment of the CJEU.

Due to the significant impact on the Bank’s result, the complexity and uncertainty of the assumptions adopted to estimate the legal risk costs of CHF mortgage loans, as well as the significant value of the portfolio constituting the basis for estimating potential settlements as well as current and potential future claims against the Bank, we considered this area a key audit matter.

Note 25 Cost of legal risk of mortgage loans in convertible currencies , Note 35 Loans and advances to customers , Note 47 Legal claims and Note 61 Management of currency risk associated with mortgage loans for individuals , Note 78 Subsequent Events in separate financial statements contain detailed information on the assumptions used to calculate the adjustment of the gross carrying amount of the portfolio of mortgage loans in CHF and provisions created, as well as the possible alternative results presented as part of the estimate sensitivity analysis.

Estimating the expected credit losses for loans and advances to customers

In accordance with the provisions of IFRS 9 the Bank's Management is required to determine expected credit loss (“ECL”) that may occur over either a 12 month period or the remaining life of a financial asset, depending on the classification of individual assets into risk categories ("stages"), taking into account the impact of future macroeconomic conditions on the level of credit risk allowances.

The Bank’s loan portfolio consists of exposures assessed for expected credit losses:

● on an individual basis for individually significant credit exposures; and

● on a portfolio basis with the use of statistical models which estimate allowances for credit losses for each of the homogenous portfolios identified by the Bank.

Estimating the level of allowances for expected credit losses requires the application of a significant degree of judgement with regard to the identification of impaired loans and significant increase in credit risk (“SICR”), the assessment of the customer's credit quality, the value of collaterals and expected recoveries.

The M anagement monitors the correctness of performance of the models, by comparing the estimated results of the models to actual credit losses (‘back-testing procedures’) to ensure that the level of allowances for the expected

As part of our procedures we updated our understanding of the internal control environment in terms of recognizing and calculating expected credit losses, and we also checked the effectiveness of selected key control mechanisms implemented by the Bank, in particular:

● procedures in the area of entering customer data used for the calculation of expected credit losses;

● the process of data flow between the Bank's key IT systems and the ECL calculation tool;

● procedures for timely and complete identification of significant increases in credit risk (stage 2) and impairment (stage 3).

We also assessed whether the methodology used by the Bank for estimating allowances for expected credit losses complies with the requirements of IFRS 9. In particular, we assessed the Bank's approach to the application of the SICR criteria, default definition, probability of default ("PD"), loss given default (“LGD”) parameters and considering forward-looking information when calculating expected credit losses.

In the case of individually insignificant loans and advances, which are assessed for expected credit losses at the portfolio basis, we have performed among others the following procedures:

● assessment of the Bank's assumptions and expert adjustments used in the model;

● critical analysis of key judgments and assumptions, including macroeconomic scenarios and assumed probabilities of occurrence of individual scenarios;

credit losses for loans and advances to customers is adequate.

In the models of expected credit losses the Bank uses large volumes of data, therefore the completeness and reliability of data can significantly impact accuracy of the allowances for credit losses.

Due to the dynamic changes taking place in the macroeconomic environment, the Bank’s Management, as described in Note 23 Net allowances for expected credit losses to separate financial statements, recognised additional write-offs for the forecasted deterioration in quality of the loan portfolio in industries particularly affected by these changes.

We determined that the level of allowance for expected credit losses in the portfolio of loans and advances is a key audit matter due to:

● the significant judgement applied by the Bank’s Management when designing future macroeconomic scenarios and forecasting macroeconomic variables, adopting probability-weighting scenarios and applying expert judgement to reflect characteristics not already considered in the models;

● a high degree of uncertainty in the estimates of expected credit losses due to the economic impacts of uncertainties resulting from macroeconomic factors which led to a high degree of auditor judgement;

● complexity of audit procedures and audit evidence obtained due to the complexity of the calculations and the volume of data used to estimate the allowances for expected credit losses.

Note 23 Net allowances for expected credit losses , Note 35 Loans and advances to customers and Note 53 the Credit risk management Note 54 Credit risk – financial information section of separate financial statements provide detailed information on the methods and models used and on the level of allowances for the expected credit losses for loans and advances to customers .

● analysis of the model stability and its adaptation to the current conditions;

● independent tests of credit risk parameters ;

● for selected loans and advances, we checked the classification into stages as at the balance sheet date.

We have engaged our in-house credit risk modelling specialists to carry out the above-mentioned procedures.

As part of the work on individually analysed exposures, we performed the following procedures:

● we applied our professional judgement in selecting the sample taking into account various risk criteria;

● for selected loans and advances we checked the classification into stages;

● for selected impaired loans and advances (stage 3), we tested the assumptions used in the calculation of the impairment allowances, in particular the forecasted scenarios and associated probabilities, as well as the timings and amounts of the expected cash flows, including cash flows from repayments and collateral realisation.

In addition, we performed the following procedures:

● we reconciled selected inputs used to determine default parameters and to estimate expected credit losses;

● we verified the assumptions adopted for the calculation of additional adjustments not included in the model, created to reflect the impact of macroeconomic factors on projected deterioration in the quality of the loan portfolio in selected industries;

● we recalculated expected credit losses on a sample of credit exposures;

● we performed analytical procedures for the coverage of the loan portfolio with expected credit losses and their changes and the transfer s of exposure s between stages;

● we analysed the events after the balance sheet date to verify the need for adjustments to be made to the expected credit losses as at the balance sheet date;

● we analysed the results of the Bank’s Management sensitivity analysis of the level of allowances for expected credit losses due to deterioration or improvement of risk parameters.

We also verified the adequacy and completeness of disclosures in the separate financial statements in accordance with the applicable accounting standards.

Estimates of interest income on loans and advances measured at amortised cost, including estimates resulting from the introduction of the act enabling customers to use the credit moratori a

In accordance with IFRS 9, interest income is recognized using the effective interest rate (EIR) method, which discounts estimated future cash flows over the expected lifetime of a financial asset to the gross carrying amount of the asset.

According to Note 15 I nterest income and expenses , interest income also includes the effect of credit moratoria, which were introduced by the Act of July 7, 2022 by the P resident of the Republic of Poland. Credit moratoria enable customers to defer repayment of selected principal and interest instalments on mortgage loans granted in PLN, which extends the repayment schedule s being the basis of calculating interest income.

The Bank adjusted the gross carrying amount of mortgage loans in PLN in correspondence with the reduction of interest income, calculated using a ratio reflecting the number of customers who have already decided to take advantage of credit moratoria and the estimated number of customers who can still submit an application and take advantage of the deferred payment (customer participation rate).

Therefore, we considered it appropriate to focus on the risk of incorrect recognition of interest income that may occur in particular in areas of significant judgement such as:

● incorrect determination of the interest income settlement period;

● recognizing interest income in incorrect amount (for example, due to a modification of a contract with a customer) or recognizing

As part of our audit, we assessed the Bank’s approach to calculati on of the adjustments of interest income due to credit moratoria, as well as scope of disclosures included in the separate financial statements regarding their compliance with the applicable accounting standards.

In particular, we have carried out the procedures listed below:

● We inquired the Bank’s specialists on the adopted estimat es and assumptions;

● We understood and evaluat ed the selected key control mechanisms for the recognition of interest income, in particular the adjustment for credit moratoria;

● We c arried our substantive procedures;

o substantive analytics on interest income on financial assets measured at amortised cost;

o verification of assumptions regarding the expected number of customers who will benefit from the credit moratoria;

o verification of the completeness and correctness of the input data used to calculate the adjustment of interest income and the gross carrying amount of loans in connection with the credit moratoria;

o re calculation of interest income adjustments due to credit moratoria on selected loan exposures .

10

interest income that is not certain to be receivable (for example, due to prepayments);

● i ncorrect estimation of the number of customers who will benefit from the credit moratoria in subsequent quarters, and thus incorrect recognition of interest income, methodological irregularities used in the calculation and incomplete or incorrect input data.

Note 15 I nterest income and expense and Note 35 L oans and advances to customers in the separate financial statements contain detailed information on the recognition methods and estimates used to recognize interest income .

Responsibility of the Management and Supervisory Board for the separate financial statements

The Management Board of the Bank is responsible for the preparation, based on the properly maintained books of account , of the annual separate financial statements that give a true and fair view of the Bank’s financial position and results of operations, in accordance with International Financial Reporting Standards as adopted by the European Union, the adopted accounting policies, the applicable laws and the Bank’s Articles of Association, and for such internal control as the Management Board determines is necessary to enable the preparation of separate financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the separate financial statements, the Bank’s Management Board is responsible for assessing the Bank’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 Management Board either intends to liquidate the Bank or to cease operations, or has no realistic alternative but to do so.

The Bank’s Management Board and members of the Supervisory Board are obliged to ensure that the separate financial statements comply with the requirements specified in the Accounting Act. Members of the Supervisory Board are responsible for overseeing the financial reporting process.

Auditor’s responsibility for the audit of the separate financial statements

Our objectives are to obtain reasonable assurance about whether the separate 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 the NSA will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in aggregate, they could reasonably be expected to influence economic decisions of users taken on the basis of these separate financial statements.

11

The scope of the audit does not include an assurance on the Bank’s future profitability nor the efficiency and effectiveness of the Bank’s Management Board conducting its affairs, now or in future.

As part of an audit in accordance with NSA, we exercise professional judgement and maintain professional scepticism throughout the audit. We also:

• identify and assess the risks of material misstatement of the separate 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 Bank’s internal control;

• evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the Bank’s Management Board;

• conclude on the appropriateness of the Bank’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 Bank’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 separate 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 Bank to cease to continue as a going concern;

• evaluate the overall presentation, structure and content of the separate financial statements, including the disclosures, and whether the separate financial statements represent the underlying transactions and events in a manner that achieves fair presentation .

We communicate with the Audit Committee 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 Audit Committee 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, actions taken to eliminate threats or safeguards applied.

From the matters communicated to the Audit Committee, we determine those matters that were of most significance in the audit of the separate 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.
