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 March 31, 2022, and the related consolidated interim statements of profit or loss, comprehensive income, changes in equity and cash flows for the three-month periods ended March 31, 2022 and 2021, 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.

Other Matters

We have audited the consolidated statement of financial position of the Group as at December 31, 2021, 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 10, 2022. The consolidated statement of financial position as at December 31, 2021, presented herein for comparative purposes, is consistent, in all material respects, with the above audited statement of financial position as at December 31, 2021.

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.

May 16, 2022

Seoul, Korea

This report is effective as of May 16, 2022, 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 amendments clarify that liabilities are classified as either current or non-current, depending on the substantive rights that exist at the end of the reporting period. Classification is unaffected by the likelihood that an entity will exercise right to defer settlement of the liability or the expectations of management. 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.

3. Critical Accounting Estimates and Assumptions

The Group makes 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 foreign 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 2022.

Significant accounting estimates and assumptions applied in the preparation of the consolidated annual 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.

The recoverable amount of goodwill was 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 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 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 March 31, 2022 and December 31, 2021, 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 three-month periods ended March 31, 2022 and 2021, are as follows:

(in millions of Korean won)	2022			2021
	Derivatives used for hedging			Derivatives used for hedging
Beginning balance	W	831		W	2,257
New transactions		—			—
Recognized at fair value through profit or loss		(356	)		(356	)
Ending balance	W	475		W	1,901

31. Events After the Reporting Period

After the current reporting period, the Controlling Company transferred its Cloud/IDC business to KT Cloud Co., Ltd., a newly established company owned by the Controlling Company, through an investment in kind on April 1, 2022. The Group aims to enhance the value of the Cloud/IDC business and foster KT Cloud Co., Ltd. as a specialized company.

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 March 31, 2022, and the related consolidated interim statements of profit or loss, comprehensive income, changes in equity and cash flows for the three-month periods ended March 31, 2022 and 2021, 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, 2021, 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 10, 2022. The consolidated statement of financial position as at December 31, 2021, presented herein for comparative purposes, is consistent, in all material respects, with the above audited statement of financial position as at December 31, 2021.

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.

May 16, 2022

Seoul, Korea

This report is effective as of May 16, 2022, 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.

(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 three-month periods ended March 31, 2022 and 2021, are as follows:

(in millions of Korean won)	2022			2021
	Derivatives used for hedging			Derivatives used for hedging
I. Beginning balance	W	831		W	2,257
II. New transactions		—			—
III. Recognized at fair value through profit or loss		(356	)		(356	)
IV. Ending balance (I+II+III)	W	475		W	1,901
