Independent Auditor’s Review Report

[English Translation of Independent Auditor’s Review Report Originally Issued in Korean on May 16, 2024]

To the Shareholders and the Board of Directors of KT Corporation.

Reviewed Consolidated Interim Financial Statements

We have reviewed the accompanying consolidated interim financial statements of KT Corporation and its subsidiaries (the “Group”). The consolidated interim financial statements consist of the consolidated statement of financial position as of March 31, 2024, and the related consolidated statements of profit or loss, comprehensive income, changes in equity and cash flows for the three-month periods ended March 31, 2024 and 2023, all expressed in Korean won, and a summary of significant accounting policies and other explanatory information.

Management’s Responsibility for the Consolidated Interim Financial Statements

Management is responsible for the preparation and fair presentation of these consolidated interim financial statements in accordance with Korean International Financial Reporting Standards (“K-IFRS”) No. 1034 Interim Financial Reporting, and for such internal control as management determines is necessary to enable the preparation of consolidated interim financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s Responsibility

Our responsibility is to express a conclusion on the accompanying consolidated interim financial statements based on our reviews.

We conducted our reviews in accordance with the Review Standards for Quarterly and Semi-annual Financial Statements established by the Securities and Futures Commission of the Republic of Korea. A review of consolidated interim financial statements consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Korean Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our reviews, nothing has come to our attention that causes us to believe that the accompanying consolidated interim financial statements referred to above do not present fairly, in all material respects, the financial position as of March 2024 and its financial performance and its cash flows for the three-month periods ended March 2024 in accordance with K-IFRS No.1034 Interim Financial Reporting.

LOGO

Other Matters

We have audited the consolidated statement of financial position as of December 31, 2023, and the related consolidated statement of profit or loss, consolidated statement of comprehensive income, consolidated statement of changes in equity and cash flows for the year then ended, which are not accompanying this report, in accordance with Korean Standards on Auditing. We expressed an unqualified opinion on those consolidated financial statements in our audit report dated March 18, 2024. The accompanying consolidated statement of financial position as of December 31, 2023, presented for comparative purposes, is not different from the audited consolidated statement of financial position above in all material respects.

2	Material Accounting Policies
2.1	Basis of Preparation
---	---

The Group maintains its accounting records in Korean won and prepares statutory financial statements in the Korean language (Hangul) in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (K-IFRS). The accompanying consolidated financial statements have been condensed, restructured and translated into English from the Korean language financial statements.

The consolidated interim financial statements of the Group for the three-month period ended March 31, 2024, have been prepared in accordance with Korean IFRS 1034 Interim Financial Reporting. In order to understand the consolidated interim financial statements, annual consolidated financial statements as of December 31, 2023 prepared in accordance with IFRS should be used together.

2.2	Changes in Accounting Policy and Disclosures

(1) New and amended standards and interpretations adopted by the Group

The Group has applied a number of new and amended standards and new interpretations issued that are effective for accounting periods beginning on January 1, 2024.

K-IFRS 1001 Presentation of Financial Statements (Amendment in 2020) – Classification of Liabilities as Current or Non-current

The amendments clarify that the classification of liabilities as current and non-current is based on rights that are existing at the end of the reporting period, specify that classification is unaffected by expectations about whether an entity will exercise its right to defer settlement of a liability, explain that rights are in existence if covenants are complied with at the end of the reporting period, and introduce a definition of ‘settlement’ to make clear that settlement refers to the transfer to the counterparty of cash, equity instruments, other assets or services.

K-IFRS 1001 Presentation of Financial Statements (Amendment in 2023) - Non-current Liabilities with Covenants

The amendments specify that only covenants that an entity is required to comply with on or before the end of the reporting period affect the entity’s right to defer settlement of a liability for at least twelve months after the reporting date. Such covenants affect whether the right exists at the end of the reporting period, even if compliance with the covenant is assessed only after the reporting date.

Notes to the Consolidated Financial Statements

The amendments also specifies that the right to defer settlement of a liability for at least twelve months after the reporting date is not affected if an entity only has to comply with a covenant after the reporting period. However, if the entity’s right to defer settlement of a liability is subject to the entity complying with covenants within twelve months after the reporting period, an entity discloses information that enables users of financial statements to understand the risk of the liabilities becoming repayable within twelve months after the reporting period. This would include information about the covenants (including the nature of the covenants and when the entity is required to comply with them), the carrying amount of related liabilities and facts and circumstances, if any, that indicate that the entity may have difficulties complying with the covenants.

K-IFRS 1007 Cash Flow Statement and K-IFRS 1107 Financial Instruments Disclosure (Amendment) - Supplier Finance Agreements

The amendments add a disclosure objective in K-IFRS 1007 Cash Flow Statement stating that an entity is required to disclose information about supplier finance agreements that enables users of financial statements to assess the effects of those arrangements on the Group’s liabilities and cash flows. In addition, K-IFRS 1107 was amended to add supplier finance arrangements as an example within the requirements to disclose information about an entity’s exposure to concentration of liquidity risk.

The term ‘supplier finance agreements’ is not defined; instead, the amendments describe the characteristics of an arrangement for which an entity would be required to provide the information.

To meet the disclosure objective, an entity will be required to disclose in aggregate for its supplier finance arrangements:

•	The terms and conditions of an agreement
•	The carrying amount, and associated line items presented in the entity’s statement of financial position, of<br>the liabilities that are part of the arrangements
---	---
•	The carrying amount, and associated line items for which the suppliers have already received payment from the<br>finance providers
---	---
•	Ranges of payment due dates for both those financial liabilities that are part of a supplier finance arrangement<br>and comparable trade payables that are not part of a supplier finance arrangement
---	---
•	Types of non-cash changes in the carrying amount of financial liabilities<br>corresponding to supplier finance agreements and their impact
---	---
•	Liquidity risk information

K-IFRS 1116 Leases (Amendment) - Lease Liability in a Sale and Leaseback

The amendments add a subsequent measurement requirement for sale and leaseback transactions that satisfy the requirements in K-IFRS 1115 Revenue from contracts with customers. The amendments require the seller-lessee to determine ‘lease payments’ or ‘revised lease payments’ in such a way that the seller-lessee does not recognise a gain or loss that relates to the right of use asset retained by the seller-lessee, after the lease commencement date.

K-IFRS 1001 Presentation of Financial Statements (Amendment in 2023) - Disclosure of Virtual Assets

The amendments, in addition to additional disclosure requirements required by other Standards for transactions related to virtual assets, are setting out the disclosure requirements in each case of 1) holding virtual assets; 2) holding virtual assets on behalf of customers; and 3) issuing virtual assets.

When holding a virtual asset, disclosure on the general information of the virtual asset, the applied accounting policy, and the acquisition method, acquisition cost, and the fair value of each virtual asset at the end of the reporting period should be disclosed. In addition, when issuing a virtual asset, the entity’s obligations and the status of fulfilment of the obligation related to the issued virtual asset, the timing and amount of the recognized revenue of the sold virtual asset, the quantity of virtual assets held after issuance, and important contract details should be disclosed.

(2) New and revised standards and interpretations in issue but not yet effective or adopted by the Group

At the date of authorization of these financial statements, the Group has not applied the following new and amended K-IFRS standards that have been issued but are not yet effective:

- K-IFRS 1021 The effects of changes in foreign exchange rates and K-IFRS 1101 First time adoption of international financial reporting- Improving Interchangeability

The amendments define situations in which exchange with other currencies is possible for accounting purposes, assess the exchangeability with other currencies and clarify the estimating and requirements for disclosure of spot exchange rates to be used in the absence of exchangeability.

If exchange for other currencies is not possible, the spot exchange rate should be estimated on the measurement date, and the observable exchange rate should be used without adjustment or other estimation techniques should be used.

The above amendments are applicable for annual reporting periods beginning on or after 1 January 2025, with early application permitted.

The Group is reviewing the impact of the above-listed amendments on the financial statements.

2.3	Accounting Policies

Material accounting policies and method of computation used in the preparation of the consolidated interim financial statements are consistent with those of the consolidated financial statements for the year ended December 31, 2023, except for the changes due to the application of amendment and enactments of standards described in Note 2.2 (1) and as described below.

(1) Income Tax Expense

Income tax expense for the interim period is recognized based on management’s best estimate of the weighted average annual income tax rate expected for the full financial year. The estimated average annual tax rate is applied to the pre-tax income of the interim period.

3	Critical Accounting Estimates and Assumptions

The preparation of financial statements requires the Group to make estimates and assumptions concerning the future. Management also needs to exercise judgement in applying the Group’s accounting policies. Estimates and assumptions are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. As the resulting accounting estimates will, by definition, seldom equal the actual results, it poses significant risk of resulting in a material adjustment.

The recoverable amount of goodwill has been determined based on the fair value obtained by calculating the value in use or deducting the cost of disposal. The pre-tax cash flow estimate was used to calculate the value of use based on the financial budget, such as the budget for the next five years. Cash flows after the estimated period were estimated using the expected growth rate, and the growth rate does not exceed the long-term average growth rate of the industry to which the cash-generating unit belongs. The Group determines the growth margin rate based on past performance and expectations of future market changes. The Group has determined pre-tax cash flow estimates based on past earnings and market growth forecasts, and the discount rate used reflects the specific risks of related operations.

(2)	Fair Value Hierarchy

To provide an indication about the reliability of the inputs used in determining fair value, the Group classifies its financial instruments into the three levels prescribed under the accounting standards. Financial instruments that are measured at fair value are categorized by the fair value hierarchy, and the defined levels are as follows:

•	Level 1: The fair value of financial instruments traded in active markets is based on quoted market prices<br>at the end of the reporting period. The quoted market price used for financial assets held by the Group is the current bid price. These instruments are included in level 1.
•	Level 2: The fair value of financial instruments that are not traded in an active market is determined using<br>valuation techniques which maximize the use of observable market data and rely as little as possible on entity-specific estimates. If all significant inputs required to fair value an instrument are observable, the instrument is included in level 2.<br>
---	---
•	Level 3: If one or more of the significant inputs is not based on observable market data, the instrument is<br>included in level 3.
---	---

Fair value hierarchy classifications of the financial assets and financial liabilities that are measured at fair value disclosed in fair value as of March 31, 2024 and December 31, 2023, are as follows:

Independent Auditor’s Review Report

[English Translation of Independent Auditor’s Review Report Originally Issued in Korean on May 16, 2023.

To the Shareholders and the Board of Directors of KT Corporation.

Reviewed Separate Interim Financial Statements

We have reviewed the accompanying separate interim financial statements of KT Corporation (the “Company”). The separate interim financial statements consist of the separate statement of financial position as of March 31, 2024, and the related separate statements of profit or loss, comprehensive income, changes in equity and cash flows for the three-month periods ended March 31, 2024 and 2023, all expressed in Korean won, and a summary of significant accounting policies and other explanatory information.

Management’s Responsibility for the Separate Interim Financial Statements

Management is responsible for the preparation and fair presentation of these separate interim financial statements in accordance with Korean International Financial Reporting Standards (“K-IFRS”) No. 1034 Interim Financial Reporting, and for such internal control as management determines is necessary to enable the preparation of separate interim financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s Responsibility

Our responsibility is to express a conclusion on the accompanying separate interim financial statements based on our reviews.

We conducted our reviews in accordance with the Review Standards for Quarterly and Semi-annual Financial Statements established by the Securities and Futures Commission of the Republic of Korea. A review of separate interim financial statements consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Korean Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our reviews, nothing has come to our attention that causes us to believe that the accompanying separate interim financial statements referred to above are not presented fairly, in all material respects, the financial position as of March 2024 and its financial performance and its cash flows for the three-month periods ended March 2024 in accordance with K-IFRS No.1034 Interim Financial Reporting.

Other Matters

We have audited the separate statement of financial position of the Company as of December 31, 2023, and the related separate statements of profit or loss, comprehensive income, changes in equity and cash flows for the year then ended, which are not accompanying this report, in accordance with Korean Standards on Auditing. We expressed an unqualified opinion on those financial statements in our audit report dated March 18, 2024. The accompanying consolidated statement of financial position as of December 31, 2023, presented for comparative purposes, is not different from the audited consolidated statement of financial position above in all material respects.

Notes to the Separate Financial Statements

As of March31, 2024 and 2023, and December 31, 2023

K-IFRS 1007 Cash Flow Statement and K-IFRS 1107 Financial Instruments Disclosure (Amendment) - Supplier Finance Agreements

The amendments add a disclosure objective in K-IFRS 1007 Cash Flow Statement stating that an entity is required to disclose information about supplier finance agreements that enables users of financial statements to assess the effects of those arrangements on the Company’s liabilities and cash flows. In addition, K-IFRS 1107 was amended to add supplier finance arrangements as an example within the requirements to disclose information about an entity’s exposure to concentration of liquidity risk.

The term ‘supplier finance agreements’ is not defined; instead, the amendments describe the characteristics of an arrangement for which an entity would be required to provide the information.

To meet the disclosure objective, an entity will be required to disclose in aggregate for its supplier finance arrangements:

•	The terms and conditions of an agreement
•	The carrying amount, and associated line items presented in the entity’s statement of financial position, of<br>the liabilities that are part of the arrangements
---	---
•	The carrying amount, and associated line items for which the suppliers have already received payment from the<br>finance providers
---	---
•	Ranges of payment due dates for both those financial liabilities that are part of a supplier finance arrangement<br>and comparable trade payables that are not part of a supplier finance arrangement
---	---
•	Types of non-cash changes in the carrying amount of financial liabilities<br>corresponding to supplier finance agreements and their impact
---	---
•	Liquidity risk information

2.3	Accounting Policies

Material accounting policies and method of computation used in the presentation of the separate interim financial statements are consistent with those of the separate financial statements for the year ended December 31, 2023, except for the changes due to the application of amendment and enactments of standards described in Note 2.2 (1) and as described below.

(1)	Income Tax Expense

Income tax expense for the interim period is recognized based on management’s best estimate of the weighted average annual income tax rate expected for the full financial year. The estimated average annual effective income tax rate is applied to the pre-tax income of the interim period.

(2)	Subsidiaries, Associates and Joint Ventures

The financial statements of the Company are the separate financial statements prepared in accordance with Korean IFRS 1027 Separate Financial Statements. Investments in subsidiaries, associates and joint ventures are recognized at cost under the direct equity method. Management applied the carrying amounts under the previous K-GAAP at the time of transition to Korean IFRS as deemed cost of investments. The Company recognizes dividend income from subsidiaries, associates and joint ventures in profit or loss when its right to receive the dividend is established.

3.	Critical Accounting Estimates and Assumptions

The preparation of financial statements requires the Company to make estimates and assumptions concerning the future. Management also needs to exercise judgement in applying the Company’s accounting policies. Estimates and assumptions are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. As the resulting accounting estimates will, by definition, seldom equal the actual results, it poses significant risk of resulting in a material adjustment.
