Report on Review of Interim Financial Statements

(English Translation of a Report Originally Issued in Korean)

To the Shareholders and Board of Directors of

KT Corporation

Reviewed Financial Statements

We have reviewed the accompanying consolidated interim financial statements of KT Corporation and its subsidiaries (collectively referred to as the “Group”). These financial statements consist of the consolidated interim statement of financial position of the Group as at September 30, 2021, and the related consolidated interim statements of profit or loss and comprehensive income for the three-month and nine-month periods ended September 30, 2021 and 2020, and consolidated interim statements of changes in equity and cash flows for the nine-month periods ended September 30, 2021 and 2020, and a summary of significant accounting policies and other explanatory notes, expressed in Korean won.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these consolidated interim financial statements in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“Korean IFRS”) 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 issue a report on these consolidated interim financial statements based on our review.

We conducted our review in accordance with quarterly or semi-annual review standards established by the Securities and Futures Commission of the Republic of Korea. A review of interim financial information 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 review, nothing has come to our attention that causes us to believe the accompanying consolidated interim financial statements are not presented fairly, in all material respects, in accordance with Korean IFRS 1034 Interim Financial Reporting.

Samil PricewaterhouseCoopers, 100 Hangang-daero, Yongsan-gu, Seoul 04386, Korea, www.samil.com

Other Matters

We have audited the consolidated statement of financial position of the Group as at December 31, 2020, and the related consolidated statements of profit or loss, comprehensive income, changes in equity and cash flows for the year then ended, in accordance with Korean Standards on Auditing. We expressed an unqualified opinion on those financial statements, not presented herein, in our audit report dated March 9, 2021. The consolidated statement of financial position as at December 31, 2020, presented herein for comparative purposes, is consistent, in all material respects, with the above audited statement of financial position as at December 31, 2020.

Review standards and their application in practice vary among countries. The procedures and practices used in the Republic of Korea to review such financial statements may differ from those generally accepted and applied in other countries.

Seoul, Korea

This report is effective as of November 15, 2021, the review report date. Certain subsequent events or circumstances, which may occur between the review report date and the time of reading this report, could have a material impact on the accompanying consolidated interim financial statements and notes thereto. Accordingly, the readers of the review report should understand that there is a possibility that the above review report may have to be revised to reflect the impact of such subsequent events or circumstances, if any.

The Group has applied the following standards and interpretations for the first time for their annual reporting period commencing January 1, 2021.

• Amendments to Korean IFRS 1116 Lease – Practical expedient for COVID-19 – Related Rent Concessions

As a practical expedient, a lessee may elect not to assess whether a rent concession occurring as a direct consequence of the COVID-19 pandemic is a lease modification, and the amounts recognized in profit or loss as a result of applying this exemption should be disclosed. The amendments do not have a significant impact on the financial statements.

In relation to interest rate benchmark reform, the amendments provide exceptions including adjust effective interest rate instead of book amounts when interest rate benchmark of financial instruments at amortized costs is replaced and apply hedge accounting without discontinuance although the interest rate benchmark is replaced in hedging relationship. The Group does not expect that these amendments have a significant impact on financial statements.

The amendments prohibit an entity from deducting from the cost of an item of property, plant and equipment any proceeds from selling items produced while the entity is preparing the asset for its intended use.

The Group is reviewing for the impact of these amendments on the financial statements

The amendments should be applied for annual periods beginning on or after January 1, 2022, and earlier application is permitted. The Group does not expect that these amendments have a significant impact on the financial statements.

• Amendments to Korean IFRS 1001 Presentation of Financial Statements – Classification of Liabilities as Current or Non-Current

Also, the settlement of liability include the transfer of the entity’s own equity instruments, however, it would be excluded if an option to settle them by the entity’s own equity instruments if compound financial instruments is met the definition of equity instruments and recognized separately from the liability. The amendments should be applied for annual periods beginning on or after January 1, 2023, and earlier application is permitted.

2.3 Significant Accounting Policies

Significant 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, 2020, except for the changes due to the application of amendment and enactments of standards described in Note 2.1 (1) and the one 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.

3. Critical Accounting Estimates and Assumptions

The preparation of financial statements requires the Group to make estimates and assumptions concerning the future. The estimates and assumptions are continuously evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the current circumstances. Actual results may differ from these estimates.

The spread of COVID-19 has been a material impact on domestic and global economy. It may have a negative impact; such as, decrease in productivity, decrease or delay in sales, collection of existing receivables and others. Accordingly, it may have a negative impact on the financial position and financial performance of the Group, and the impact is expected to be continued to the consolidated annual financial statements in 2021.

Significant accounting estimates and assumptions applied in the preparation of the consolidated interim financial statements can be adjusted depending on changes in the uncertainty from COVID-19. Also, the ultimate effect of COVID-19 to the Group’s business, financial position and financial performance cannot presently determined.

(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 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 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.

• Level 3: If one or more of the significant inputs is not based on observable market data, the instrument is included in level 3.

Fair value hierarchy classifications of the financial assets and financial liabilities that are measured at fair value or its fair value is disclosed as at September 30, 2021 and December 31, 2020, are as follows:

(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 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.

In relation to this, details and changes of total deferred differences for the nine-month periods ended September 30, 2021 and 2020, are as follows:

(in millions of Korean won)	2021			2020

Report on Review of Interim Financial Statements

(English Translation of a Report Originally Issued in Korean)

To the Shareholders and Board of Directors of

KT Corporation

Reviewed Financial Statements

We have reviewed the accompanying separate interim financial statements of KT Corporation (the “Company”). These financial statements consist of the separate interim statement of financial position as at September 30, 2021, and the related separate interim statements of profit or loss and comprehensive income for the three-month and nine-month periods ended September 30, 2021 and 2020, and separate interim statements of changes in equity and cash flows for the nine-month periods ended September 30, 2021 and 2020, and a summary of significant accounting policies and other explanatory notes, expressed in Korean won.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these separate interim financial statements in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“Korean IFRS”) 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 issue a report on these separate interim financial statements based on our review.

We conducted our review in accordance with quarterly or semi-annual review standards established by the Securities and Futures Commission of the Republic of Korea. A review of interim financial information 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 Standard 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 review, nothing has come to our attention that causes us to believe the accompanying separate interim financial statements do not present fairly, in all material respects, in accordance with Korean IFRS 1034 Interim Financial Reporting.

Other Matters

We have audited the separate statement of financial position of the Company as at December 31, 2020, and the related separate statements of profit or loss, comprehensive income, changes in equity and cash flows for the year then ended, in accordance with Korean Standards on Auditing. We expressed an unqualified opinion on those financial statements, not presented herein, in our audit report dated March 9, 2021. The separate statement of financial position as at December 31, 2020, presented herein for comparative purposes, is consistent, in all material respects, with the above audited statement of financial position as at December 31, 2020.

Review standards and their application in practice vary among countries. The procedures and practices used in the Republic of Korea to review such financial statements may differ from those generally accepted and applied in other countries.

November 15, 2021

This report is effective as of November 15, 2021, the review report date. Certain subsequent events or circumstances, which may occur between the review report date and the time of reading this report, could have a material impact on the accompanying separate interim financial statements and notes thereto. Accordingly, the readers of the review report should understand that there is a possibility that the above review report may have to be revised to reflect the impact of such subsequent events or circumstances, if any.

• Amendments to Korean IFRS 1116 Lease – Practical expedient for COVID-19—Related Rent Concessions

As a practical expedient, a lessee may elect not to assess whether a rent concession occurring as a direct consequence of the COVID-19 pandemic is a lease modification, and the amounts recognized in profit or loss as a result of applying this exemption should be disclosed.

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, 2020, except for the changes due to the application of amendment and enactments of standards described in Note 2.1 (1) and the one 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.

(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, joint ventures and associates 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, joint ventures and associates 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. The estimates and assumptions are continuously evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the current circumstances. Actual results may differ from these estimates.

The spread of COVID-19 has been a material impact on domestic and global economy. It may have a negative impact; such as, decrease in productivity, decrease or delay in sales, collection of existing receivables and others. Accordingly, it may have a negative impact on the financial position and financial performance of the Company, and the impact is expected to be continued to the separate annual financial statements in 2021.

Significant accounting estimates and assumptions applied in the preparation of the separate interim financial statements can be adjusted depending on changes in the uncertainty from COVID-19. Also, the ultimate effect of COVID-19 to the Company’s business, financial position and financial performance cannot presently determined.

¹  The Company did not conduct a fair value estimation since the book amount is a reasonable approximation of fair value.

²  With the application of Korean IFRS 1107, lease receivables and lease liabilities are excluded from fair value disclosure.

(2) Fair Value Hierarchy

To provide an indication about the reliability of the inputs used in determining fair value, the Company 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 at the end of the reporting period. The quoted market price used for financial assets held by the Company 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 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.

• Level 3: If one or more of the significant inputs is not based on observable market data, the instrument is included in level 3.

(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 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. However, in the case that the inputs of the valuation method become observable in markets, the remaining deferred difference is immediately recognized in full in profit or loss.

In relation to this, details and changes of the total deferred difference for the nine-month periods ended September 30, 2021 and 2020, are as follows:

(in millions of Korean won)	2021			2020
	Derivatives used for hedging			Derivatives used for hedging
I. Beginning balance	W	2,257		W	3,682
II. New transactions		—			—
III. Recognized at fair value through profit or loss		(1,069	)		(1,069	)
IV. Ending balance (I+II+III)	W	1,188		W	2,613
