Table of Contents

In order to strengthen its sales channels, the Company has been offering a variety of fixed-line and wireless telecommunications convergence products through its subsidiary, PS&Marketing. PS&Marketing provides differentiated service to customers through the establishment of new sales channels and product development. Through its subsidiary Service Ace, the Company operates customer service centers and provides telemarketing services. Additionally, SK O&S, the Company’s subsidiary responsible for the operation of the Company’s networks, provides customers with quality network services and provides the Company with technological know-how in network operations.

The Company has been maintaining solid profitability based on the stable sales generated from its 5G subscribers, together with efficient investments in, and operation of, its wireless networks and stabilization of market competition. The Company’s 5G wireless services, which recorded 15.93 million subscribers as of March 31, 2024, accounted for 70% of the Company’s total number of subscribers. The Company continually seeks growth in the number of its 5G wireless subscribers while actively implementing artificial intelligence (“AI”) technology into its fixed-line and wireless businesses, thereby continuing efforts to optimize efficiencies in operational and capital expenditures.

In addition, the Company has been promoting growth in its enterprise business by developing various AI-related business items, including AI contact centers, vision AI and big data, while continuing efforts to increase demand for the Company’s Internet of Things (“IoT”) lines. For the three months ended March 31, 2024, the Company’s enterprise business recorded an increase in revenue of approximately 10% compared to the three months ended March 31, 2023. In particular, based mainly on recurring revenue, the Company’s cloud business recorded an increase in revenue of approximately 40% for the three months ended March 31, 2024 compared to the three months ended March 31, 2023, thereby driving the revenue growth of the Company’s overall enterprise business.

“A. (Adot),” the Company’s Korean language GPT-3 based service, has resonated with the market by introducing call recording and summarization features, and it continues to innovate customers’ communication experience, including by introducing real-time interpretation service during calls. In April 2024, the Company expanded A.’s call recording and summarization features as well as real-time interpretation service during calls, which have been highly popular among iPhone users, to devices run on the Google Android operating system.

B. Industry Characteristics

The telecommunications services market can be categorized into telecommunications services (such as fixed-line, wireless and leased line services, as well as sales intermediary services relating thereto and value-added services) and broadcasting and telecommunications convergence services (including IPTV and integrated fixed-line and mobile telecommunications services). Pursuant to the Telecommunications Business Act, the telecommunications services market can be further classified into basic telecommunications (fixed-line and wireless telecommunications), special category telecommunications (resale of telecommunications equipment, facilities and services) and value-added telecommunications (Internet connection and management, media contents and others).

The size of the domestic telecommunications services market is determined based on various factors specific to Korea, including the size of the population that uses telecommunications services and telecommunications expenditures per capita. While it is possible for Korean telecommunications service providers to provide services abroad through acquisitions or otherwise, foreign telecommunications services markets have their own characteristics depending, among others, on the regulatory environment and demand for telecommunications services.

C. Growth Potential

The Korean mobile communications market is considered to have reached its maturation stage with more than a 100% penetration rate. However, the Korean mobile communications market continues to improve in the quality of services with the help of advances in network-related technology and the development of highly advanced smartphones which enable the provision of new ICT services for advanced multimedia contents, mobile commerce, mobility and other related services. In addition, the ultra-low latency and high capacity characteristics of 5G networks as well as the advancement of AI are expected to accelerate the introduction of new services and the growth of IoT-based B2B businesses.

D. Domestic and Overseas Market Conditions

The Korean mobile communications market includes the entire population of Korea with mobile communications service needs, and almost every Korean is considered a potential user. Sales revenue related to data services has been growing due to the increasing popularity of smartphones and high-speed wireless networks. There is also a growing importance of the B2B segment, which creates added value by selling and developing various solutions. The telecommunications industry is a regulated industry requiring license and approval from the MSIT.

In the wireless business, industry players compete on the basis of the following three main competitive elements:

(i) brand competitiveness, which refers to the overall sense of recognition and loyalty experienced by customers with respect to services and values provided by a company, including the images created by a company’s comprehensive activities and communications on top of the actual services rendered;

(ii) product and service competitiveness, which refers to the fundamental criteria for wireless telecommunications services, including voice quality, service coverage, broad ranges of rate plans, diversified mobile Internet services, price and quality of devices, and customer service quality, as well as the ability to develop new services that meet customer needs in a market environment defined by convergence; and

(iii) sales competitiveness, which refers to novel and diversified marketing methods and the strength of the distribution network.

Set forth below is the historical market share of the Company (excluding MVNO subscribers).

E. Competitive Strengths
--- ---

In 2021, the Company successfully completed the Spin-off of SK Square Co., Ltd. from SK Telecom (the “Spin-off”) in order to maximize shareholder value. In the same year, the Company also unveiled its “SKT 2.0” vision to pursue the maximization of its overall enterprise value centered around five major business areas. In November 2022, the Company announced its differentiated “AI Company” vision to further organize and clarify the direction of SKT 2.0 and combine AI with connectivity technologies based on its main telecommunications business. In September 2023, as part of the Company’s effort to transform into a “global AI company,” the Company announced its new “AI Pyramid” strategy, which aims to bring innovation across various industrial and lifestyle areas centered around three key aspects. The AI Pyramid strategy is in the form of a pyramid and integrates a “self-reinforcement model,” which seeks to strengthen the Company’s relationship with its customers through advances in the Company’s AI technology and the creation of AI services, with a “cooperation model,” which focuses on AI-related alliances. Through these initiatives, the Company is striving to transform into a global AI company.

For the three months ended March 31, 2024, the Company recorded Won 4.47 trillion in operating revenue and Won 0.50 trillion in operating profit on a consolidated basis. The increased competitiveness of telecommunications services and the rapid progress in new growth businesses such as B2B have enabled the Company to continue to improve its operating results.

[Fixed-line Business]

A. Overview

For the three months ended March 31, 2024, SK Broadband recorded Won 1.09 trillion in revenue on a consolidated basis, which represented a 2.7% increase from Won 1.06 trillion for the three months ended March 31, 2023. Such increase was primarily attributable to the growth of SK Broadband’s media business resulting from an increase in the number of subscribers and the growth of its B2B business primarily focused on new data centers.

SK Broadband’s business is divided into the media business segment, which provides IPTV and cable TV services, and the fixed-line business segment, which provides high-speed Internet, telecommunications, leased lines and data center services.

For the three months ended March 31, 2024, the media business segment recorded Won 0.48 trillion in revenue, which represented a 0.9% increase compared to the three months ended March 31, 2023. For the three months ended March 31, 2024, the fixed-line business segment recorded Won 0.61 trillion in revenue, which represented a 4.3% increase compared to the three months ended March 31, 2023.

B. Industry Characteristics

The domestic telecommunications service industry displays the typical characteristics of a domestic industry given that its coverage area is limited to Korea. As a result, the size of the industry is greatly affected by the domestic economic factors including the domestic user population and the level of telecommunications service expenditures in light of the domestic income level. Domestic telecommunications companies may expand overseas through acquisitions or direct expansion, but the overseas telecommunications service industries are subject to inherently different industry characteristics from the domestic one, depending on the regulatory and demand characteristics of each country.

The broadcasting business involves the planning, programming or production of broadcasting programs and transmission to viewers through telecommunications facilities. The broadcasting market can be categorized into terrestrial broadcasting, fixed-line TV broadcasting, satellite broadcasting and programming-providing businesses, in each case pursuant to the Broadcasting Act, as well as Internet multimedia broadcasting business pursuant to the Internet Multimedia Broadcast Services Act. The Company engages in the fixed-line TV broadcasting business, which is defined as the business of managing and operating fixed-line TV broadcasting stations (including their facilities and employees for the purpose of providing multi-channel broadcasting) and providing broadcasts through transmission and line facilities. The Internet multimedia broadcasting refers to the broadcasting of programs through a combination of various contents including data, video, voice, sound and/or e-commerce, including real-time broadcasting, while guaranteeing a consistent service quality through a bidirectional Internet protocol using a broadband integrated information network.

As a result of the government’s direct and indirect control over the fixed-line telecommunications industry, ranging from service licensing to business activities, the industry’s overall growth potential and degree of competition are greatly affected by the government’s regulatory policies. The fixed-line telecommunications industry is also a technology-intensive industry that evolves rapidly and continuously through the development of communications technology and equipment, which requires proactive responses in meeting the needs of subscribers by developing new services and penetrating the market. Fixed-line telecommunications services have become universal and essential means of communication and act as the foundation for integration and convergence with various other services. The essential nature of such services provides stable demand, resulting in low sensitivity to economic conditions.

Table of Contents

In addition, the Korean fixed-line services industry is marked by a high level of market concentration, as the government is highly selective in granting telecommunications business licenses. While the competitive landscape of the fixed-line and wireless services markets is dominated by its three leading operators, the Company (including SK Broadband), KT and LG U+, the intensity of competition is growing as digitalization of communication technologies and devices leads to the convergence of fixed-line and wireless services, as well as broadcasting and telecommunications, and technology for faster data communications services is developed.

In the high-speed Internet services market, the demand for Giga Internet services has been continuing to increase due to the popularization of mobile and home IoT devices and the expansion of large media services including video streaming services.

In the paid broadcasting market, competition for content has been intensifying, at the center of which are large over-the-top operators with strength in exclusive content. Reflecting a rapid change in content consumption patterns and behaviors of viewers, the Company is preparing for new growth in the home platform domain by providing customized services using ICT convergence technologies such as AI and big data in addition to differentiated contents.

In the corporate business market, the Company expects to see growth in new business areas, following the emergence of new services including AI. The Company is continuing its efforts to generate stable returns by strengthening its competitiveness in the traditional fixed line-based business through expansion of core infrastructure including data centers and leased lines, for which market demand has been continually growing.

High-speed Internet and fixed-line telephone services operate in mature markets that are comparatively less sensitive to cyclical economic changes as the services provided by different operators have become less differentiated. TV services have become necessities that provide broadcasting, and the market, which is subject to a subscriber-based business model, has little sensitivity to cyclical economic changes.

C. Business-related Pollutants and Environmental Protection

[SK Telecom]

The Company does not directly engage in any manufacturing and therefore does not undertake any industrial processes that emit pollutants into the air or industrial processes in which hazardous materials are used. Nevertheless, the Company clearly recognizes the severity of the climate crisis and has been diligently fulfilling its social obligations by establishing a systematic and practical environmental management strategy system. Under the vision of “realizing a sustainable future based on ICT” and to achieve Net Zero by 2050, the Company is making efforts to (1) preemptively respond to climate change, (2) improve its environmental management system and (3) create an eco-friendly green culture. To this end, the Company was one of the first information technology companies in Korea to join the RE100 (Renewable Electricity 100%) initiative and signed a green premium contract with Korea Electric Power Corporation. The Company has been implementing company-wide adoption of renewable energy through efforts such as installing solar power generation equipment in its office buildings and base stations. In addition, the Company leads in energy savings and environmental protections based on ICT technology, and recently became the first company in the telecommunications industry to obtain carbon emission rights by reducing greenhouse gas through integration of telecommunications equipment and technology upgrades.

[SK Broadband]

SK Broadband does not directly engage in any manufacturing processes that emit environmental pollutants, and more than 99% of its greenhouse gas emissions is indirect emissions from its use of external electricity. SK Broadband was selected as a business subject to allocation of emission permits as part of Korea’s greenhouse gas emissions trading scheme that commenced in 2015, and it actively fulfills its obligations and consistently achieves the targets set by the government.

In 2021, SK Broadband declared its goal to achieve Net Zero by 2045 in an effort to actively participate in the international community’s response to climate change. Prior to the declaration, SK Broadband had already subscribed to the RE100 initiative in 2020. Since 2021, SK Broadband has participated in Korea Electrical Power Corporation’s renewable energy power purchase program, “Green Premium,” to purchase renewable energy and has installed additional solar power generation facilities to increase the self-production and use of renewable energy.

--- ---

The Company establishes loss allowances based on the likelihood of recoverability of trade and other receivables based on their aging at the end of the period and past customer default experience for the past three years. With respect to trade receivables relating to wireless telecommunications services, the Company considers the likelihood of recovery based on past customer default experience and the length of default in connection with the type of default (e.g., whether the customer’s service has been terminated or is continued). Consistent with customary practice, the Company writes off trade and other receivables for which the prescription period has passed or that are determined to be impossible or economically too costly to collect, including receivables that are less than Won 200,000 and more than six months overdue and receivables that have been determined to be the subject of identity theft.

Report on review of interim consolidated financial statements

(English translation of a report originally issued in Korean)

The Shareholders and Board of Directors

SK TelecomCo., Ltd.

We have reviewed the accompanying interim consolidated financial statements of SK Telecom Co., Ltd. and its subsidiaries (collectively referred to as the “Group”), which comprise the interim consolidated statement of financial position as of March 31, 2024, and the related interim consolidated statements of income, interim consolidated statements of comprehensive income, interim consolidated statements of changes in equity and interim consolidated statements of cash flows for each of the three-month periods ended March 31, 2024 and 2023, and a summary of material accounting policy information and other explanatory information.

Management’s responsibility for the interim consolidated financial statements

Management is responsible for the preparation and fair presentation of these interim consolidated financial statements in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“KIFRS”) 1034 Interim Financial Reporting, and for such internal control as management determines is necessary to enable the preparation of interim consolidated 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 these interim consolidated financial statements based on our review.

We conducted our review in accordance with the Review Standards for Quarterly and Semiannual Financial Statements 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 (“KSA”) 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 that the accompanying interim consolidated financial statements are not prepared fairly, in all material respects, in accordance with KIFRS 1034 Interim Financial Reporting.

Table of Contents

LOGO

Other matters

We have audited the consolidated statement of financial position as of December 31, 2023, and the related consolidated statement of income, consolidated statement of comprehensive income, consolidated statement of changes in equity and consolidated statement of cash flows for the year then ended (not presented herein) in accordance with KSA, and our report dated March 6, 2024 expressed an unqualified opinion thereon. The accompanying consolidated statement of financial position as of December 31, 2023 presented for comparative purposes is not different, in all material respects, from the above audited consolidated statement of financial position.

May 13, 2024

This report is effective as of May 13, 2024, the independent auditor’s review report date. Accordingly, certain material subsequent events or<br>circumstances may have occurred during the period from the date of the independent auditor’s review report to the time this review report is used. Such events and circumstances could significantly affect the accompanying interim consolidated<br>financial statements and may result in modification to this review report.

2. Basis of Preparation
(1) Statement of compliance
--- ---

These interim condensed consolidated financial statements were prepared in accordance with International Financial Reporting Standard as adopted by the Republic of Korea (“KIFRS”) 1034 Interim Financial Reporting as part of the period covered by the Group’s KIFRS annual financial statements. These interim consolidated financial statements do not include all of the disclosures required for full annual financial statements. Selected explanatory notes are included to explain events and transactions that are significant to an understanding of the changes in financial position and performance of the Group since December 31, 2023. The accompanying interim consolidated financial statements have been translated into English from the Korean language financial statements. In the event of any differences in interpreting the financial statements or the independent auditor’s review report thereon, the Korean version, which is used for regulatory reporting purposes, shall prevail.

(2) Use of estimates and judgments
1) Critical judgments, assumptions and estimation uncertainties
--- ---

The preparation of the interim consolidated financial statements in conformity with KIFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates.

In preparing these interim consolidated financial statements, the significant judgments made by management in applying the Group’s accounting policies and the key sources of estimation uncertainty were the same as those that applied to the consolidated financial statements as of and for the year ended December 31, 2023.

2. Basis of Preparation, Continued
(2) Use of estimates and judgments, Continued
--- ---
2) Fair value measurement
--- ---

The Group’s accounting policies and disclosures require the measurement of fair values, for both a number of financial and non-financial assets and liabilities. The Group has established policies and processes with respect to the measurement of fair values, including Level 3 fair values, and the measurement of fair values is reviewed and is directly reported to the finance executives.

The Group regularly reviews significant unobservable inputs and valuation adjustments. If third party information, such as broker quotes or pricing services, is used to measure fair values, then the Group assesses the evidence obtained from the third parties to support the conclusion that such valuations meet the requirements of KIFRS, including the level in the fair value hierarchy in which such valuations should be classified.

When measuring the fair value of an asset or a liability, the Group uses market observable data as far as possible. Fair values are categorized into different levels in a fair value hierarchy based on the inputs used in the valuation techniques as follows:

Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities;<br>
Level 2: inputs other than quoted prices included in Level 1 that are observable for the asset or<br>liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and
--- ---
Level 3: inputs for the asset or liability that are not based on observable market data (unobservable<br>inputs).
--- ---

If the inputs used to measure the fair value of an asset or a liability fall into different levels of the fair value hierarchy, then the fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level input that is significant to the entire measurement. The Group recognizes transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred.

Information about assumptions used for fair value measurements are included in Note 29.

5. Trade and Other Receivables, Continued
(2) Changes in the loss allowance on trade and other receivables measured at amortized cost for the three-month<br>periods ended March 31, 2024 and 2023 are as follows:
--- ---
(In millions of won)
--- --- --- --- --- --- --- --- --- --- --- ---

~~W~~ 325,002 11,254 (1,990 ) 3,107 337,373
(*) The Group writes off trade and other receivables that are determined to be uncollectable due to reasons such as<br>termination of operations or bankruptcy.
--- ---
(3) The Group applies the practical expedient that allows the Group to estimate the loss allowance for accounts<br>receivable – trade at an amount equal to the lifetime expected credit losses. The expected credit losses include the forward-looking information. To make the assessment, the Group uses its historical credit loss experience over the past three<br>years and classifies the accounts receivable – trade by their credit risk characteristics and days overdue.
--- ---

As the Group is a wireless and fixed-line telecommunications service provider, the Group’s financial assets measured at amortized cost primarily consist of receivables from numerous individual customers, and, therefore, no significant credit concentration risk arises.

Receivables related to other revenue mainly consist of receivables from corporate customers. The Group transacts only with corporate customers with credit ratings that are considered to be low at credit risk. In addition, the Group is not exposed to significant credit concentration risk as the Group regularly assesses their credit risk by monitoring their credit ratings. While the contract assets are under the impairment requirements, no significant credit risk has been identified.

29. Financial Risk Management
(1) Financial risk management
--- ---

The Group is exposed to market risk, credit risk and liquidity risk. Market risk is the risk related to the changes in market prices, such as foreign exchange rates, interest rates and price fluctuations. The Group implements a risk management system to monitor and manage these specific risks.

The Group’s financial assets consist of cash and cash equivalents, financial instruments, long-term investment securities, accounts receivable – trade and other, etc. Financial liabilities consist of accounts payable – trade and other, borrowings, debentures, lease liabilities and others.

1) Market risk
(i) Currency risk
--- ---

The Group incurs exchange position due to revenues and expenses from its global operations. Major foreign currencies where currency risk exists are USD, EUR and others. The Group determines its currency risk management policy after considering the nature of business and the presence of methods that mitigate the currency risk on each Group entity basis. The Group regularly evaluates, manages and reports foreign exchange exposure risk through the management systems to receivables and payables denominated in foreign currencies. Currency risk occurs on forecasted transactions and recognized assets and liabilities which are denominated in a currency other than the functional currency of each group entity.

Monetary assets and liabilities denominated in foreign currencies as of March 31, 2024 are as follows:

(In millions of won, thousands of foreign currencies) Liabilities
Won<br>equivalent Foreign<br>currencies Wonequivalent
85,508 ~~W~~ 115,163 1,033,837 ~~W~~ 1,392,371

Others 347 67
~~W~~ 138,871 ~~W~~ 1,392,503

All values are in US Dollars.

In addition, the Group has entered into cross currency swaps to hedge against currency risk related to foreign debentures.

As of March 31, 2024, a hypothetical change in exchange rates by 10% would have increased (decreased) the Group’s profit before income tax as follows:

(In millions of won) Equity

1) Market risk, Continued

(ii) Interest rate risk

The interest rate risk of the Group arises from borrowings, debentures and long-term payables – other. Since the Group’s interest bearing assets are mostly fixed-interest bearing assets, the Group’s revenue and operating cash flows from the interest-bearing assets are not influenced by the changes in market interest rates.

The Group performs various analysis to reduce interest rate risk and to optimize its financing. To minimize risks arising from changes in interest rates, the Group takes various measures such as refinancing, renewal, alternative financing and hedging.

As of March 31, 2024, floating-rate borrowings and debentures amount to ~~W~~80,000 million and ~~W~~404,040 million, respectively, and the Group has entered into interest rate swaps to hedge interest rate risk related to the floating-rate debentures. Therefore, profit before income tax for the three-month period ended March 31, 2024 would not have been affected by the changes in interest rates of floating-rate debentures.

If the interest rate increases (decreases) 1%p with all other variables held constant, profit before income taxes and equity for the three-month period ended March 31, 2024, would change by ~~W~~200 million in relation to the floating-rate borrowings which have not entered into interest rate swaps.

As of March 31, 2024, the floating-rate long-term payables – other are ~~W~~921,075 million. If the interest rate increases (decreases) 1%p with all other variables held constant, profit before income tax and equity for the three-month period ended March 31, 2024, would change by ~~W~~2,303 million in relation to the floating-rate long-term payables – other that are exposed to interest rate risk.

(iii) Price fluctuations risk

As of March 31, 2024, the Group holds equity instruments in an active trading market and is exposed to price fluctuation risk accordingly. Assuming all other variables remain constant, the impact of changes in per-share stock price of the equity securities on profit before income tax and equity for the three-month period ended March 31, 2024 is as follows.

(In millions of won) Profit before income tax Equity
If increased by 10% If decreased by 10% If increased by 10% If decreased by 10%

The maximum credit exposure as of March 31, 2024 and December 31, 2023 are as follows:

(In millions of won) March 31, 2024 December 31, 2023
Cash and cash equivalents ~~W~~ 1,718,775 1,454,773

Derivative financial assets 194,481 148,534
~~W~~ 5,586,929 5,074,338

Credit risk is the risk of financial loss to the Group if a customer or counterparty to a financial instrument fails to meet its contractual obligations. To manage credit risk, the Group evaluates the credit worthiness of each customer or counterparty by considering the party’s financial information, its own trading records and other factors. Based on such information, the Group establishes credit limits for each customer or counterparty.

The Group establishes a loss allowance in respect of accounts receivable – trade. The main components of this allowance are a specific loss component that relates to individually significant exposures and a collective loss component established for groups of similar assets in respect of losses that are expected to occur. The collective loss allowance is determined based on historical data of collection statistics for similar financial assets. Also, the Group’s credit risk can arise from transactions with financial institutions related to its cash and cash equivalents, financial instruments and derivatives. To minimize such risk, the Group has a policy to deal only with financial institutions with high credit ratings. The amount of maximum exposure to credit risk of the Group is the carrying amount of financial assets as of March 31, 2024.

The above information does not include fair values of financial assets and liabilities of which fair values have not been measured as carrying amounts are reasonable approximation of fair values.

Fair value of the financial instruments that are traded in an active market (financial assets at FVOCI and financial assets at FVTPL) is measured based on the bid price at the end of the reporting date.

The Group uses various valuation methods for determination of fair value of financial instruments that are not traded in an active market. Derivative financial contracts and long-term liabilities are measured using the discounted present value methods. Other financial assets are determined using the methods, such as discounted cash flow and market approach. Inputs used to such valuation methods include swap rate, interest rate, and risk premium, and the Group performs valuation using the inputs which are consistent with natures of assets and liabilities measured.

Interest rates used by the Group for the fair value measurement as of March 31, 2024 are as follows:

Interest rate
Derivative instruments 2.56% ~ 6.25%
Borrowings and debentures 3.64% ~ 18.12%
Long-term payables – other 3.64% ~ 3.81%

Report on review of interim separate financial statements

(English translation of a report originally issued in Korean)

The Shareholders and Board of Directors

SK TelecomCo., Ltd.

We have reviewed the accompanying interim separate financial statements of SK Telecom Co., Ltd. (collectively referred to as the “Company”), which comprise the interim separate statement of financial position as of March 31, 2024, and the related interim separate statements of income, interim separate statements of comprehensive income, interim separate statements of changes in equity and interim separate statements of cash flows for each of the three-month periods ended March 31, 2024 and 2023, and a summary of material accounting policy information and other explanatory information.

Management’s responsibility for the interim separate financial statements

Management is responsible for the preparation and fair presentation of these interim separate financial statements in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“KIFRS”) 1034 Interim Financial Reporting, and for such internal control as management determines is necessary to enable the preparation of interim separate 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 these interim separate financial statements based on our review.

We conducted our review in accordance with the Review Standards for Quarterly and Semiannual Financial Statements 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 (“KSA”) 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 that the accompanying interim separate financial statements are not prepared fairly, in all material respects, in accordance with KIFRS 1034 Interim Financial Reporting.

Table of Contents

Other matters

We have audited the separate statement of financial position as of December 31, 2023, and the related separate statement of income, separate statement of comprehensive income, separate statement of changes in equity and separate statement of cash flows for the year then ended (not presented herein) in accordance with KSA, and our report dated March 6, 2024 expressed an unqualified opinion thereon. The accompanying separate statement of financial position as of December 31, 2023 presented for comparative purposes is not different, in all material respects, from the above audited separate statement of financial position.

May 13, 2024

This report is effective as of May 13, 2024, the independent auditor’s review report date. Accordingly, certain material subsequent events or<br>circumstances may have occurred during the period from the date of the independent auditor’s review report to the time this review report is used. Such events and circumstances could significantly affect the accompanying interim separate<br>financial statements and may result in modification to this review report.

Notes to the Interim Separate Financial Statements

March 31, 2024 and 2023 (Unaudited)

1. Reporting Entity

SK Telecom Co., Ltd. (“the Company”) was incorporated on March 29, 1984, under the laws of the Republic of Korea (“Korea”) to provide cellular telephone communication services in Korea. The head office of the Company is located at 65, Eulji-ro, Jung-gu, Seoul, Korea.

The Company’s common shares are listed on the Stock Market of Korea Exchange, and its depositary receipts (DRs) are listed on the New York Stock Exchange. As of March 31, 2024, the Company’s total issued shares are held by the following shareholders:

Number of shares Percentage oftotal shares issued (%)
SK Inc. 65,668,397 30.57
National Pension Service 16,374,544 7.62
Institutional investors and other shareholders 126,991,437 59.13
Kakao Investment Co., Ltd. 3,846,487 1.79
Treasury shares 1,909,188 0.89
214,790,053 100.00
2. Basis of Preparation
--- ---
(1) Statement of compliance
--- ---

These interim condensed separate financial statements were prepared in accordance with International Financial Reporting Standard as adopted by the Republic of Korea (“KIFRS”) 1034 Interim Financial Reporting as part of the period covered by the Company’s KIFRS annual financial statements. These interim separate financial statements do not include all of the disclosures required for full annual financial statements. Selected explanatory notes are included to explain events and transactions that are significant to an understanding of the changes in financial position and performance of the Company since December 31, 2023. The accompanying interim separate financial statements have been translated into English from the Korean language financial statements. In the event of any differences in interpreting the financial statements or the independent auditor’s review report thereon, the Korean version, which is used for regulatory reporting purposes, shall prevail.

These interim financial statements are interim separate financial statements prepared in accordance with KIFRS 1027, Separate FinancialStatements, presented by a parent, an investor with joint control of or significant influence over an investee, in which the investments are accounted for at cost less impairment, if any.

2. Basis of Preparation, Continued
(2) Use of estimates and judgments
--- ---

1) Critical judgments, assumptions and estimation uncertainties

The preparation of the interim separate financial statements in conformity with KIFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates.

In preparing these interim separate financial statements, the significant judgments made by management in applying the Company’s accounting policies and the key sources of estimation uncertainty were the same as those that applied to the separate financial statements as of and for the year ended December 31, 2023.

2) Fair value measurement

The Company’s accounting policies and disclosures require the measurement of fair values, for both a number of financial and non-financial assets and liabilities. The Company has established policies and processes with respect to the measurement of fair values including Level 3 fair values, and the measurement of fair values is reviewed and is directly reported to the finance executives.

The Company regularly reviews significant unobservable inputs and valuation adjustments. If third party information, such as broker quotes or pricing services, is used to measure fair values, then the Company assesses the evidence obtained from the third parties to support the conclusion that such valuations meet the requirements of KIFRS, including the level in the fair value hierarchy in which such valuations should be classified.

When measuring the fair value of an asset or a liability, the Company uses market observable data as far as possible. Fair values are categorized into different levels in a fair value hierarchy based on the inputs used in the valuation techniques as follows:

•  Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities;
•  Level 2: inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and
•  Level 3: inputs for the asset or liability that are not based on observable market data (unobservable inputs).

If the inputs used to measure the fair value of an asset or a liability fall into different levels of the fair value hierarchy, then the fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level input that is significant to the entire measurement. The Company recognizes transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred.

Information about assumptions used for fair value measurements are included in note 28.

3. Material Accounting Policies

The material accounting policies applied by the Company in these interim separate financial statements are the same as those applied by the Company in its separate financial statements as of and for the year ended December 31, 2023, except for the adoption of new and revised KIFRS applied from January 1, 2024, which are summarized below. The Company has not early applied the new and revised KIFRS and interpretations that have been issued but are not yet effective.

The following new and amended KIFRS and interpretations are effective from January 1, 2024, initially, but these amended standards are not expected to have a material impact on the Company’s interim separate financial statements.

(2) Changes in the loss allowance on trade and other receivables measured at amortized cost for the three-month<br>periods ended March 31, 2024 and 2023 are as follows:

~~W~~ 160,680 8,257 (407 ) 2,461 170,991
(*) The Company writes off trade and other receivables that are determined to be uncollectable due to reasons such<br>as termination of operations or bankruptcy.
--- ---
(3) The Company applies the practical expedient that allows the Company to estimate the loss allowance for accounts<br>receivable – trade at an amount equal to the lifetime expected credit losses. The expected credit losses include the forward-looking information. To make the assessment, the Company uses its historical credit loss experience over the past three<br>years and classifies the accounts receivable – trade by their credit risk characteristics and days overdue.
--- ---

As the Company is a wireless telecommunications service provider, the Company’s financial assets measured at amortized cost primarily consist of receivables from numerous individual customers, and, therefore, no significant credit concentration risk arises.

Receivables related to other revenue mainly consist of receivables from corporate customers. The Company transacts only with corporate customers with credit ratings that are considered to be low at credit risk. In addition, the Company is not exposed to significant credit concentration risk as the Company regularly assesses their credit risk by monitoring their credit ratings. While the contract assets are under the impairment requirements, no significant credit risk has been identified.

28. Financial Risk Management
(1) Financial risk management
--- ---

The Company is exposed to market risk, credit risk and liquidity risk. Market risk is the risk related to the changes in market prices, such as foreign exchange rates, interest rates and price fluctuations. The Company implements a risk management system to monitor and manage these specific risks.

The Company’s financial assets consist of cash and cash equivalents, financial instruments, long-term investment securities, accounts receivable – trade and other, etc. Financial liabilities consist of accounts payable – trade and other, borrowings, debentures, lease liabilities and others.

1) Market risk
(i) Currency risk
--- ---

The Company’s currency risk is mainly related to changes in recognized assets and liabilities due to exchange rate fluctuations. If the Company determines that it is necessary to hedge currency risk for business purposes, the Company manages currency risk by using currency swaps, etc. Currency risk occurs on forecasted transactions and recognized assets and liabilities which are denominated in a currency other than the functional currency of the Company.

Monetary assets and liabilities denominated in foreign currencies as of March 31, 2024 are as follows:

(In millions of won, thousands of foreign currencies) Liabilities
Won equivalent Foreign currencies Won equivalent
24,857 ~~W~~ 33,478 710,265 ~~W~~ 956,585
11,656 16,935 45 65
Others 347 67
~~W~~ 50,760 ~~W~~ 956,717

All values are in US Dollars.

In addition, the Company has entered into cross currency swaps to hedge against currency risk related to foreign currency debentures.

As of March 31, 2024, a hypothetical change in exchange rates by 10% would have increased (decreased) the Company’s profit before income tax and equity as follows:

(In millions of won) Equity

28. Financial Risk Management, Continued
(1) Financial risk management, Continued

1) Market risk, Continued
--- ---
(ii) Interest rate risk
--- ---

The interest rate risk of the Company arises from borrowings, debentures and long-term payables – other. Since the Company’s interest-bearing assets are mostly fixed-interest bearing assets, the Company’s revenue and operating cash flows from the interest-bearing assets are not influenced by the changes in market interest rates.

The Company performs various analysis to reduce interest rate risk and to optimize its financing. To minimize risks arising from changes in interest rates, the Company takes various measures, such as refinancing, renewal, alternative financing and hedging.

As of March 31, 2024, floating-rate borrowings and debentures amount to ~~W~~30,000 million and ~~W~~404,040 million, respectively, and the Company has entered into interest rate swaps to hedge interest rate risk related to the floating-rate debentures. Therefore, profit before income tax for the three-month period ended March 31, 2024 would not have been affected by the changes in interest rates of floating-rate debentures. If the interest rate increases (decreases) 1%p with all other variables held constant, profit before income tax and equity for the three-month period ended March 31, 2024, would change by ~~W~~75 million in relation to the floating-rate borrowings which have not entered into interest rate swaps.

As of March 31, 2024, the floating-rate long-term payables – other are ~~W~~921,075 million. If the interest rate increases (decreases) 1%p with all other variables held constant, profit before income tax and equity for the three-month period ended March 31, 2024, would change by ~~W~~2,303 million in relation to the floating-rate long-term payables – other that are exposed to interest rate risk.

(iii) Price fluctuations risk

As of March 31, 2024, the Company holds equity instruments in an active trading market and is exposed to price fluctuation risk accordingly. Assuming all other variables remain constant, the impact of changes in per-share stock price of the equity securities on profit before income tax and equity for the three-month period ended March 31, 2024 is as follows.

(In millions of won) Profit before income tax Equity
If increased by 10% If decreased by 10% If increased by 10% If decreased by 10%

The maximum credit exposure as of March 31, 2024 and December 31, 2023 are as follows:

(In millions of won) March 31, 2024 December 31, 2023
Cash and cash equivalents ~~W~~ 885,754 631,021

~~W~~ 3,821,604 3,339,879

Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails to meet its contractual obligations. To manage credit risk, the Company evaluates the credit worthiness of each customer or counterparty by considering the party’s financial information, its own trading records and other factors. Based on such information, the Company establishes credit limits for each customer or counterparty.

The Company establishes a loss allowance in respect of accounts receivable – trade. The main components of this allowance are a specific loss component that relates to individually significant exposures and a collective loss component established for groups of similar assets in respect of losses that are expected to occur. The collective loss allowance is determined based on historical data of collection statistics for similar financial assets. Also, the Company’s credit risk can arise from transactions with financial institutions related to its cash and cash equivalents, financial instruments and derivatives. To minimize such risk, the Company has a policy to deal only with financial institutions with high credit ratings.

The Company’s maximum exposure to credit risk is equal to each financial asset’s carrying amount as of March 31, 2024.

--- ---

The above information does not include fair values of financial assets and liabilities of which fair values have not been measured as carrying amounts are reasonable approximation of fair values.

Fair value of the financial instruments that are traded in an active market (financial assets at FVOCI) is measured based on the bid price at the end of the reporting date.

The Company uses various valuation methods for determination of fair value of financial instruments that are not traded in an active market. Derivative financial contracts and long-term liabilities are measured using the discounted present value methods. Other financial assets are determined using the methods, such as discounted cash flow and market approach. Inputs used to such valuation methods include swap rate, interest rate and risk premium, and the Company performs valuation using the inputs which are consistent with natures of assets and liabilities measured.

Interest rates used by the Company for the fair value measurement as of March 31, 2024 are as follows:

Interest rate
Derivative instruments 3.80% ~ 4.90%
Borrowings and debentures 3.64% ~ 3.84%
Long-term payables – other 3.64% ~ 3.81%
