Independent Auditor’s Review Report

[English Translation of Independent Auditor’s Review Report Originally Issued in Korean on November 14, 2023]

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 September 30, 2023, and the related consolidated statements of profit or loss, comprehensive income, changes in equity and cash flows for the nine-month periods ended September 30, 2023 and 2022, 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 September 2023 and its financial performance and its cash flows for the nine-month periods ended September 2023 in accordance with K-IFRS No.1034 Interim Financial Reporting.

Other Matters

The accompanying consolidated interim statements of profit or loss, comprehensive income, changes in equity and cash flows for the nine-month period ended September 30, 2022 for comparative purpose, were reviewed by other auditors, whose report thereon dated November 14, 2022, expressed that nothing came to their attention that caused them to believe that those consolidated interim financial statements as of September 30, 2022 were not prepared fairly, in all material respects, in accordance with K-IFRS.

The consolidated statement of financial position as of December 31, 2022, and the related consolidated statements of profit or loss, comprehensive income, changes in equity and cash flows for the year then ended, which are not accompanying this report, were audited by other auditors, whose report thereon dated March 8, 2023, expressed an unqualified opinion. The accompanying statement of financial position as of December 31, 2022, presented for comparative purposes, is not different from that audited by other auditors in all material respects.

The Controlling Company, in accordance with the Korea Telecommunications Corporation Act, was established as a 100% government-invested institution on January 1, 1982, when it comprehensively succeeded the telegraph and telephone business from the Korea Communications Commission (former Ministry of Information and Communication) to promote management of public telecommunications business and communication technology, and to contribute to improvement of public welfare.

On May 29, 1999, the Controlling Company was listed on the New York Stock Exchange by issuing a stock depository certificate containing newly issued 24,282,195 shares of common stock along with 20,813,311 shares held by the government. On July 2, 2001, a stock depository certificate containing 55,502,161 stocks held by the government was additionally issued and listed on the New York Stock Exchange.

Notes to the Consolidated Interim Financial Statements

September 30, 2023 and 2022 (Unaudited), and December 31, 2022

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 (“Korean IFRS” or “K-IFRS”). The accompanying consolidated interim 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 nine-month period ended September 30, 2023, have been prepared in accordance with Korean IFRS 1034 Interim Financial Reporting. These consolidated interim financial statements have been prepared in accordance with Korean IFRS which is effective or has been early adopted as of September 30, 2023.

2.2	Changes in Accounting Policies and Disclosures
(1)	New and amended standards and interpretations adopted by the Group
---	---

The Group has applied the following standards and interpretations for the first time for their annual reporting period commencing January 1, 2023.

•	K-IFRS 1001 Presentation of Financial Statements and IFRSPractice Statement 2 Making Materiality Judgements - Disclosure of Accounting Policies (Amendment)

The amendments change the requirements in K-IFRS 1001 with regard to disclosure of accounting policies. The amendments replace all instances of the term ‘significant accounting policies’ with ‘material accounting policy information’. Accounting policy information is material if, when considered together with other information included in an entity’s financial statements, it can reasonably be expected to influence decisions that the primary users of general-purpose financial statements make on the basis of those financial statements.

The supporting paragraphs in K-IFRS 1001 are also amended to clarify that accounting policy information that relates to immaterial transactions, other events or conditions is immaterial and need not be disclosed. Accounting policy information may be material because of the nature of the related transactions, other events or conditions, even if the amounts are immaterial. However, not all accounting policy information relating to material transactions, other events or conditions is itself material.

September 30, 2023 and 2022 (Unaudited), and December 31, 2022

•	K-IFRS 1001 Presentation of Financial Statements - Disclosure of<br>financial liabilities with condition to adjust exercise price (Amendment)

The amendments require disclosure of valuation gains or losses (limited to those recognized in the profit or loss) of the conversion options or warrants (or financial liabilities including them), if all or part of the financial instrument with exercise price that is adjusted depending on the issuer’s share price change is classified as financial liability as defined in paragraph 11 (2) of K-IFRS 1032.

•	K-IFRS 1008 Accounting Polices, Changes in Accounting Estimates andErrors - Definition of Accounting Estimates (Amendment)

The amendments replace the definition of a change in accounting estimates with a definition of accounting estimates. Under the new definition, accounting estimates are “monetary amounts in financial statements that are subject to measurement uncertainty”.

The definition of a change in accounting estimates was deleted. However, the KASB retained the concept of changes in accounting estimates in the Standard with the following clarifications:

•	A change in accounting estimate that results from new information or new developments is not the correction of an<br>error
•	The effects of a change in an input or a measurement technique used to develop an accounting estimate are changes<br>in accounting estimates if they do not result from the correction of prior period errors

September 30, 2023 and 2022 (Unaudited), and December 31, 2022

•	K-IFRS 1012 Income Taxes - Deferred Tax related to Assets and<br>Liabilities arising from a Single Transaction (Amendment)

The amendments introduce a further exception from the initial recognition exemption. Under the amendments, an entity does not apply the initial recognition exemption for transactions that give rise to equal taxable and deductible temporary differences.

Depending on the applicable tax law, equal taxable and deductible temporary differences may arise on initial recognition of an asset and liability in a transaction that is not a business combination and affects neither accounting nor taxable profit. For example, this may arise upon recognition of a lease liability and the corresponding right-of-use asset applying K-IFRS 1116 at the commencement date of a lease.

Following the amendments to K-IFRS 1012, an entity is required to recognise the related deferred tax asset and liability, with the recognition of any deferred tax asset being subject to the recoverability criteria in K-IFRS 1012.

The amendments apply to transactions that occur on or after the beginning of the earliest comparative period presented. In addition, at the beginning of the earliest comparative period an entity recognises:

•	A deferred tax asset (to the extent that it is probable that taxable profit will be available against which the<br>deductible temporary difference can be utilised) and a deferred tax liability for all deductible and taxable temporary differences associated with:
①	Right-of-use assets and lease<br>liabilities
---	---
②	Decommissioning, restoration and similar liabilities and the corresponding amounts recognised as part of the<br>cost of the related asset
---	---
•	The cumulative effect of initially applying the amendments is recognized as an adjustment to the opening balance<br>of retained earnings (or other component of equity, as appropriate) at that date.

(2) New standards and interpretations not yet adopted by the Group

The amended accounting standard issued that is not mandatory for the annual reporting period commencing January 1, 2023 and has not been early adopted by the Group is as follows:

•	K-IFRS 1001 Presentation of Financial Statements - Classification<br>of Liabilities as Current or Non-current (Amendment)

The amendments clarify that the classification of liabilities as current or non-current is based on rights that are in existence 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.

In addition, 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.

The amendments also specify that the right to defer settlement 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.

The above amendments are applied retrospectively for annual reporting periods beginning on or after 1 January 2024, with early application permitted.

The Group is in review for the impact of the above amendments on the Group’s consolidated 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, 2022, 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.

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 was determined based on calculation of the value in use or fair value less costs of disposal. The pre-tax cash flow estimate was used to calculate the value in 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 sales growth rate based on past performance and expectations of future market fluctuations. The Group has determined 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.

(5)	Valuation Processes for Fair Value Measurements Categorized Within Level 3
---	---

The Group uses external experts that perform the fair value measurements required for financial reporting purposes. External experts report directly to the Chief Financial Officer (CFO) and discuss the valuation processes and results with the CFO in line with the Group’s closing dates.

(6)	Gains and Losses on Valuation at the Transaction Date

In the case that the Group values derivative financial instruments using inputs not based on observable market data, and the fair value calculated by valuation methods using such data differs from the transaction price, then the fair value of the financial instrument is recognized at the transaction price. The difference between the fair value at initial recognition and the transaction price is deferred and amortized using a straight-line method by maturity of the financial instrument. However, in the case that the inputs of the valuation methods become observable in markets, the remaining deferred difference is immediately recognized in full in profit or loss.

Independent Auditor’s Review Report

[English Translation of Independent Auditor’s Review Report Originally Issued in Korean on November 14, 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 September 30, 2023, and the related separate statements of profit or loss, comprehensive income, changes in equity and cash flows for the nine-month periods ended September 30, 2023 and 2022, 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 do not present fairly, in all material respects, the financial position as of September 2023 and its financial performance and its cash flows for the nine-month periods ended September 2023 in accordance with K-IFRS No.1034 Interim Financial Reporting.

LOGO

Other Matters

The accompanying separate interim statements of profit or loss, comprehensive income, changes in equity and cash flows for the nine-month period ended September 30, 2022 for comparative purpose, were reviewed by other auditors, whose report thereon dated November 14, 2022, expressed that nothing came to their attention that caused them to believe that those separate interim financial statements as of September 30, 2022 were not prepared fairly, in all material respects, in accordance with K-IFRS.

The separate statement of financial position as of December 31, 2022, 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, were audited by other auditors, whose report thereon dated March 8, 2023, expressed an unqualified opinion. The accompanying statement of financial position as of December 31, 2022, presented for comparative purposes, is not different from that audited by other auditors in all material respects.

2.2	Changes in Accounting Policies and Disclosures

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

The Company has applied the following standards and interpretations for the first time for their annual reporting period commencing January 1, 2023.

K-IFRS 1001 Presentation of Financial Statements and IFRSPractice Statement 2 Making Materiality Judgements - Disclosure of Accounting Policies (Amendment)

The amendments change the requirements in K-IFRS 1001 with regard to disclosure of accounting policies. The amendments replace all instances of the term ‘significant accounting policies’ with ‘material accounting policy information’. Accounting policy information is material if, when considered together with other information included in an entity’s financial statements, it can reasonably be expected to influence decisions that the primary users of general purpose financial statements make on the basis of those financial statements.

K-IFRS 1001 Presentation of Financial Statements - Disclosure of financial liabilities with condition to adjust exercise price (Amendment)

K-IFRS 1008 Accounting Polices, Changes in Accounting Estimates and Errors - Definition of Accounting Estimates (Amendment)

The definition of a change in accounting estimates was deleted. However, the KASB retained the concept of changes in accounting estimates in the Standard with the following clarifications:

•	A change in accounting estimate that results from new information or new developments is not the correction of an<br>error
•	The effects of a change in an input or a measurement technique used to develop an accounting estimate are changes<br>in accounting estimates if they do not result from the correction of prior period errors

•	A deferred tax asset (to the extent that it is probable that taxable profit will be available against which the<br>deductible temporary difference can be utilised) and a deferred tax liability for all deductible and taxable temporary differences associated with:
①	Right-of-use assets and lease<br>liabilities
---	---
②	Decommissioning, restoration and similar liabilities and the corresponding amounts recognised as part of the<br>cost of the related asset

2.3	Significant Accounting Policies

Significant 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, 2022, 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

(2) Subsidiaries, Associates and Joint Ventures

The financial statements of the Company are the separate financial statements prepared in accordance with Korean IFRS 1027 SeparateFinancial 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.

(5)	Valuation Processes for Fair Value Measurements Categorized Within Level 3

The Company uses external experts that perform the fair value measurements required for financial reporting purposes. External experts report directly to the Chief Financial Officer (CFO) and discuss the valuation processes and results with the CFO in line with the Company’s closing dates.

(6)	Gains and Losses on Valuation at the Transaction Date

In the case that the Company values derivative financial instruments using inputs not based on observable market data, and the fair value calculated by valuation methods using such data differs from the transaction price, then the fair value of the financial instrument is recognized at the transaction price. The difference between the fair value at initial recognition and the transaction price is deferred and amortized using a straight-line method by maturity of the financial instrument.
