[Wireless Business]

A. Industry Characteristics

The telecommunications services market can be categorized into telecommunications services (such as fixed-line, wireless, leased line and value-added services) and broadcasting and telecommunications convergence 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 size of population that uses telecommunication services and telecommunications expenditures per capita. While it is possible for Korean telecommunication service providers to provide services abroad through acquisitions or otherwise, foreign telecommunication services markets have their own characteristics depending, among others, on the regulatory environment and demand for telecommunication services.

The Korean mobile communication 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. Business Overview and Competitive Strengths

The Company is seeking to transform into a comprehensive ICT service provider. In light of the ongoing COVID-19 pandemic, the Company has quickly adapted to the contactless environment based on its diverse ICT portfolio and is continuing to show steady growth in each of its major business divisions, including MNO, media, security and commerce.

For the six months ended June 30, 2021, the Company recorded Won 9.6 trillion in operating revenue and Won 785.4 billion in profit for the period on a consolidated basis, and it recorded Won 6 trillion in operating revenue and Won 635.7 billion in profit for the period on a separate basis.

In the MNO business, the Company secured 7.7 million 5G subscribers as of June 30, 2021 through innovations and quality enhancements in its 5G services. The Company also solidified its status as the top MNO service operator while maintaining market stability through innovations in its distribution channels in response to the contactless environment and rational market operations.

[Fixed-line Business]

A. Industry Characteristics

The domestic telecommunication 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 telecommunication service expenditures in light of the domestic income level. Domestic telecommunication companies may expand overseas through acquisitions or direct expansion, but the overseas telecommunication service industries are subject to inherently different industry charicteristics 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 telecommunication 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 governments direct and indirect control over the fixed-line telecommunications industry, ranging from service licensing to business activities, the industrys overall growth potential and degree of competition are greatly affected by the governments 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.

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 communication services is developed.

In the high speed internet services market, the demand for faster and more reliable premium Giga Internet services is increasing due to the growth in usage of home mobile networks using Wi-Fi and an increased consumption of high-definition large media content.

With the mergers and acquisitions among IPTV service providers and multiple service operators, the paid broadcasting market has reorganized around IPTV operators, and companies are moving away from competition based on subscriber base expansion to competition based on media platform services. The transition to a contactless service society due to COVID-19 has led to increased consumption of paid content by viewers, accelerating competition through the ability to source unique contents. The Company expects 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.

Table of Contents

In the corporate business market, the Company is continuing its efforts to generate stable returns by securing growth drivers in new service areas such as cloud computing, while also strengthening its competitiveness in the traditional fixed line-based business through infrastructure expansion.

C. Cyclical Nature and Seasonality

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. The telecommunications services market overall is not expected to be particularly affected by economic downturns due to the low income elasticity of demand for telecommunication services.

[Security Business]

A. Industry Characteristics

The security systems service business provides security services to governments, companies and individuals with the purpose of protecting tangible and intangible assets and human resources. Depending on the risk prevention method used, the security business can be classified into machine-based security, security system integration (SI), information security and manned security. Machine-based security operates by receiving information that is detected and transmitted by various sensors and cameras installed at the target facilities through control facility equipment and taking prompt and appropriate action, such as dispatching an agent or contacting the police or the fire department, if an abnormality is detected. Security SI is a service that integrates installation, operation, maintenance and repair of various equipment and systems by analyzing the appropriate security system for customer facilities, such as buildings, factories and schools. Manned security services deploy security personnel to areas subject to security, who perform on-site security services such as patrols and access control of buildings and facilities. The information security industry involves the business of providing security to business customers to prevent the leakage and hacking of data, including personal information. The industry can be categorized into the information security product business, which includes the development, manufacturing and distribution of information security products, and the information security service business, such as security consulting and managed security services. Information security products aim to form a secure cyber environment by protecting computer terminals and Internet communication channels, while information security services provide security across the overall ICT industry by providing security consulting services to companies on how to protect their information security assets or through managed security services, which prevent security breaches by hackers.

The Companys primary business in the physical security industry is its unmanned security and security SI services, and the Companys primary business in the information security industry is its managed security and security consulting services. Its business areas consist of the following:

C. Cyclical Nature and Seasonality

The security business seeks to satisfy the basic need for safety and is less sensitive to economic fluctuations compared to other industries. Although the slowdown in the Korean economy and competition based on lower-cost alternatives has had a negative impact on industry growth, sustained growth is nevertheless expected due to the recent expansion of the industry into converged security markets with the integration of ICT.

D. Domestic and Overseas Market Conditions

The security industry is experiencing a rapid increase in demand for CCTV, access control and other security systems due to threats including crime, natural disasters and calamities and terrorism. With increased consumer interest in safety, demand for security system services is expected to continue to grow. To date, the Korean security market is characterized by an oligopoly dominated by three leading companies due to the high barriers to entry as a result of high initial investment costs of building large-scale network systems and the effects of brand loyalty. The traditional security industry, characterized by price competition aimed at increasing market share, is expanding into a converged security market with the integration of ICT. In addition, the global converged security market integrating ICT has recently been experiencing rapid growth and increased competition due to the entry of global information technology companies.

Furthermore, the importance of the information security industry is steadily increasing due to the diversified and increasingly advanced and intelligent attacks by hackers, and the demand for information security is expected to increase exponentially due to the digital transformation arising from advances in new technologies, such as AI, IoT, cloud and smart factories, as part of the fourth industrial revolution. Although global information security companies are demonstrating strength in the domestic information security market for products, the top three domestic companies have traditionally dominated the market for services.

The security industry, which received attention for pioneering a new market for day-to-day disease prevention measures in response to the COVID-19 pandemic, demonstrated growth despite various obstacles. In the post-COVID-19 era, which is expected to begin in 2022 after the wide administration of vaccines, the growth of the security industry is expected to accelerate further due to the convergence of physical security and cybersecurity as well as the advancement of integrated control centers for the stable operation and development of smart cities.

Table of Contents

As a result, although the size of the domestic security market in 2020 failed to reach Won 6 trillion in light of the effects of COVID-19, it is expected to grow annually by 3.9% to Won 6.4 trillion in 2021 and by 5.2% to Won 6.3 trillion in 2022.

E. Business Overview and Competitive Strengths

For the six months ended June 30, 2021, ADT CAPS recorded Won 684.9 billion in operating revenue and Won 67.8 billion in operating profit, and it secured approximately 710,000 subscribers as of June 30, 2021, including subscribers to information security services.

Due to the saturation of the unmanned security market, there was no significant change in the number of ADT CAPS unmanned security contracts in 2020 compared to the previous year. However, ADT CAPS was able to maintain consistent growth in the number of new subscribers acquired through the SK distribution network and a continued increase in revenue from the CAPS Home and parking services. In addition, despite the economic downturn due to COVID-19, ADT CAPS was able to pave new markets for contactless access control and fever detection services using facial recognition and thermal imaging cameras.

Revenue from the information security business of ADT CAPS exceeded Won 300 billion, making ADT CAPS the first company to do so in the industry. ADT CAPS is widening the gap with the second-largest player in the information security market and has maintained its top position in the market for the past five years.

Although the unmanned security market is expected to remain saturated in 2021, ADT CAPS will pursue efforts to improve the results of operations and service quality of its core unmanned security business through the development of products and market approaches that are tailored to the needs of various customers, while also improving its new security businesses, including the information security business, by enhancing its technologies and diversifying its product portfolio through further development efforts and the increased use of AI.

Former ADT CAPS merged with SK Infosec, a cybersecurity service provider, and the combined ADT CAPS is considering business synergies from various perspectives to provide a more diverse range of high-quality services to customers, including converged security products, in the future.

Unmanned security services range from crime prevention based on cutting-edge sensors and prompt dispatch of security personnel to follow-up services. With increased efforts to reduce false alarms, ADT CAPS continues to reduce dispatch and control costs, thereby improving service quality and ultimately generating new sources of revenue to establish a positive cycle for continuous growth.

Video security services provide objective security through full identification of subjects with the use of high-definition video, made convenient and safe through a diverse lineup of products and remote control services. Access security services provide outsider access control, employee attendance checks and even drinking water management, which are made user-friendly and convenient due to the integration of cutting edge AI-based technology such as fingerprint, facial and mobile recognition. ADT CAPS plans to continue advancing such technology-based services and deliver more convenient and safer security services to customers through innovative technologies.

The SI business provides comprehensive security solutions suitable for the management of large buildings, such as access control and energy, fire safety and parking management services.

[Commerce Business]

A. Industry Characteristics

Electronic commerce, or e-commerce, refers to transactions of goods and services that are processed electronically by information processing systems, such as personal computers, and can be classified into online order and online order brokerage businesses. The mail order brokerage business refers to the act of intermediating a transaction between a seller and a buyer by an online shopping mall, and the online order business refers to direct sales of goods and services by an online shopping mall. Online shopping malls can be categorized, based on the range of products that they handle, into special malls that handle products limited to specific categories and general malls that handle products across multiple categories. The Korean e-commerce market started to grow in the early 2000s with the spread of the Internet, and it is now going through a second period of growth in the form of mobile commerce as a result of the removal of time and space constraints on shopping following the proliferation of smartphones beginning in 2010, the simplification and improved convenience of payment services, the expansion of fast delivery services following intense competition in such services beginning in 2018, the combination of offline and online shopping experiences (omni-channel and O2O services) and advancements in personalization and recommendation services based on AI. Eleven Street, which operates an online order brokerage business, is known as an open market business operator within the e-commerce market. As a result of leading the trend of mobile commerce and pursuing innovative customer experience since the early stages of its business, Eleven Street has grown into a major player in the e-commerce market.

B. Growth Potential

As of December 31, 2020, the size of the Korean e-commerce market was Won 161.1 trillion, accounting for approximately 34% of the total online and offline distribution market and demonstrating rapid growth at an annual average growth rate of over 19% for the past three years. In addition, mobile transactions accounted for 67.5% of the total e-commerce transaction value in 2020, after surpassing 50% for the first time in 2016. Considering the current acceleration in the shift of products traditionally sold offline, such as food products, food delivery services, apparels and household products, to the mobile e-commerce platform and with the expansion of contactless consumption of goods in light of COVID-19, mobile e-commerce is expected to continue its growth in the future.

Year — E-commerce transaction value (trillion Won)	161.1	135.3	113.3	94.2	65.6
Annual growth rate	19.1 %	19.3 %	20.3 %	43.6 %	21.5 %

C. Cyclical Nature and Seasonality

While the commerce industry is inherently affected by fluctuations in the economy to a certain extent, their effect on the e-commerce market has been limited due to its ongoing rapid growth.

D. Domestic and Overseas Market Conditions

The mobile-centered online commerce market is expected to grow steadily due to the further growth potential of the Internet shopping population, the development of online business models by offline commerce operators and the growth of mobile commerce. New business models are expected to emerge and proliferate into new markets as diverse lifestyle services that go beyond commodities are incorporated into the area of commerce.

2. Dividends and Others

A. Dividend Policy

Our fundamental shareholder distribution policy seeks to enhance long-term shareholder returns through stable cash dividends based on the Companys performance and through the enhancement of corporate value based on sustained growth. To this end, the Company strives to enhance its corporate value under its capital management principle of balancing investment for growth and shareholder returns.

In addition, the Company determines its shareholder return in consideration of a comprehensive set of factors including its business performance, investment plans, financial status and prospects, and the Company may make shareholder return in the form of cash or shares in accordance with its articles of incorporation. Cash dividends are determined based on the Companys consideration of investment needs for its continued future growth as well as its annual business performance and overall cash flow status. In the case of share dividends, the type of the shares to be distributed may be determined pursuant to the resolution of the Companys general meeting of shareholders, to the extent there are multiple classes of shares outstanding.

The Company distributes annual dividends to shareholders or pledgees registered on its shareholders register as of the end of each fiscal year, and the Company distributed an interim dividend once a year as of June 30 pursuant to the resolution of its board of directors. In order to further enhance the Companys policy to provide continual shareholder return and in accordance with the global trend towards stable dividend distribution, the Company adopted a quarterly dividend distribution policy in place of its previous interim dividend distribution policy through the approval of certain amendments to the Companys articles of incorporation at the 37 th General Meeting of Shareholders held on March 25, 2021. On July 22, 2021, the board of directors resolved to approve the first quarterly dividends.

Furthermore, the Company repurchases its own shares from time to time to enhance its corporate value in consideration of the market price of the Companys shares and its financial resources. In 2020 and 2021 to date, the Company purchased approximately Won 500 billion of treasury shares through a trustee. In May 2021, the Company canceled 8,685,568 units of previously acquired treasury shares, which represented 10.76% of the total number of shares issued at the time, to enhance shareholder value.

Independent Auditors Review Report

Based on a report originally issued in Korean

To the Board of Directors and Shareholders

SK Telecom Co., Ltd.:

Reviewed financial statements

We have reviewed the accompanying condensed consolidated interim financial statements of SK Telecom Co., Ltd. and its subsidiaries (the Group), which comprise the condensed consolidated statement of financial position as of June 30, 2021, the condensed consolidated statements of income and comprehensive income for the three and six-month periods ended June 30, 2021 and 2020, the condensed consolidated statements of changes in equity and cash flows for the six-month periods ended June 30, 2021 and 2020, and notes, comprising a summary of significant accounting policies and other explanatory information.

Managements responsibility

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

Auditors review responsibility

Our responsibility is to issue a report on these condensed consolidated interim financial statements based on our reviews.

We conducted our reviews 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 principally 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 condensed consolidated interim financial statements referred to above are not prepared fairly, in all material respects, in accordance with K-IFRS No.1034, Interim Financial Reporting .

Other matters

The consolidated statement of financial position of the Group as of December 31, 2020, and the related consolidated statements of income, comprehensive income, changes in equity and cash flows for the year then ended, which are not accompanying this report, were audited by us in accordance with Korean Standards on Auditing and our report thereon, dated March 11, 2021, expressed an unqualified opinion. The accompanying condensed consolidated statement of financial position of the Group as of December 31, 2020, presented for comparative purposes, is consistent, in all material respects, with the audited consolidated financial statements from which it has been derived.

The procedures and practices utilized in the Republic of Korea to review such condensed consolidated interim financial statements may differ from those generally accepted and applied in other countries.

Notes to the Condensed Consolidated Interim Financial Statements

For the six-month periods ended June 30, 2021 and 2020

Basis of Preparation

(1) Statement of compliance

These condensed consolidated interim financial statements were prepared in accordance with Korean International Financial Reporting Standard (K-IFRS) No. 1034, Interim Financial Reporting , as part of the period covered by the Groups K-IFRS 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, 2020. These condensed consolidated interim financial statements do not include all of the disclosures required for full annual financial statements.

(2) Use of estimates and judgments

1) Critical judgments, assumptions and estimation uncertainties

The preparation of the condensed consolidated interim financial statements in conformity with K-IFRS 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 condensed consolidated interim financial statements, the significant judgments made by management in applying the Groups 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, 2020.

(2) Use of estimates and judgments, Continued

2) Fair value measurement

A number of the Groups accounting policies and disclosures require the measurement of fair values, for both 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 K-IFRS, 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;

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 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 30.

Significant Accounting Policies

(1) Except as described below, the accounting policies applied in these interim financial statements are the same as those applied in the Groups consolidated financial statements as at and for the year ended December 31, 2020. The change in accounting policy will also be reflected in the Groups consolidated financial statements as at and for the year ending December 31, 2021.

The Group has initially adopted Interest Rate Benchmark Reform Phase 2 Amendments to K-IFRS No. 1109, Financial Instruments , K-IFRS No. 1039, Financial Instrument: Recognition and Measurement , K-IFRS No. 1107, Financial Instruments: Disclosures and K-IFRS No. 1116, Leases from January 1, 2021.

Interest Rate Benchmark Reform Phase 2 Amendments provide exceptions as follows:

when a change required by interest rate benchmark reform occurs to a financial asset or financial liability measured at amortized cost, the Group updates the effective interest rate of the financial asset or financial liability rather than the carry amount and,

when a change required by interest rate benchmark reform occurs to a hedged item and/or hedging instrument, the exception permits the hedge relationship to be continued without interruption.

These amended standards are not expected to have a significant impact on the Groups consolidated financial statements.

(2) During the annual period ended December 31, 2020, the Group changed its accounting policy by applying agenda decision, Lease Term and Useful Life of Leasehold Improvements (IFRS 16 Leases and IAS 16 Property, Plant and Equipment)November 2019 , published by International Financial Reporting Interpretations Committee (IFRIC) on December 16, 2019. Due to the changes in accounting policies in connection with the IFRIC agenda, the Group restated its comparative financial statements for the six-month period ended June 30, 2020.

The following table summarizes the impacts of the change in accounting policy on the Groups condensed consolidated interim financial statements.

(2) Changes in the loss allowance on trade and other receivables measured at amortized cost for the six-month periods ended June 30, 2021 and 2020 are as follows:

	W	346,399	32,406	(21,770	)	6,286	1,879	365,200

(*) The Group writes off the trade and other receivables that are determined to be uncollectable due to reasons such as termination of operations or bankruptcy.

(3) The Group applies the practical expedient that allows the Group to estimate the loss allowance for accounts 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 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 Groups 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 rating. While the contract assets are under the impairment requirements, no significant credit risk has been identified.

Derivative Instruments

In relation to the paid-in capital increase of T Map Mobility Co., Ltd., a subsidiary of the Parent Company, for the six-month period ended June 30, 2021, the Parent Company has entered into a shareholders agreement with the acquirer of newly issued shares. Pursuant to the agreement, when certain conditions are met within a period of time subsequent to the paid-in capital increase, the acquirer of newly issued shares can exercise their drag-along rights and require the Parent Company to sell its shares of T Map Mobility Co., Ltd. should the subscriber of newly issued shares exercise their drag-along rights, the Parent Company also can exercise its call options over the shares held by those shareholders. The Group recognized a derivative financial liability of W 88,613 million for the rights included in the shareholders agreement as of June 30, 2021.

The underlying asset is the total equity value of T Map Mobility Co., Ltd. calculated by multiplying the unit price per share ( W 87,418) as of the date of shareholders agreement which is the base of calculation by the total number of shares issued (16,090,548 shares). The fair value of the derivative financial liability was determined by using the binomial model based on various assumptions including the price of common stock and the possibility of exercising the right. There is no significant difference in fair values between the date of shareholders agreement and June 30, 2021, and the significant unobservable inputs used in the fair value measurement and inter-relationship between significant unobservable inputs and fair value measurement are as below:

Significant unobservable inputs	Correlations between inputs and fair value measurements
Fair value of T Map Mobility Co., Ltd.s common stock after the paid-in capital increase	The estimated fair value of derivative liabilities would decrease (increase) if the fair value of
common stock would increase (decrease)
Volatility	The estimated fair value of derivative liabilities would decrease (increase) if the volatility of
stock price increase (decrease)

Financial Risk Management

(1) Financial risk management

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

The Groups financial assets consist of cash and cash equivalents, financial instruments, investment securities and accounts receivable trade and others, 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 revenue and expenses from its global operations. Major foreign currencies where the currency risk occurs are USD, EUR and JPY. The Group determines the currency risk management policy after considering the nature of business and the presence of methods that mitigate the currency risk for each Group entities. 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. The Group manages currency risk arising from business transactions by using currency forwards, etc.

Monetary assets and liabilities denominated in foreign currencies as of June 30, 2021 are as follows:

(In millions of won, thousands of foreign currencies)
Assets			Liabilities
Foreign currencies		Won equivalent	Foreign currencies		Won equivalent
USD	91,569	W	103,473	1,550,350	W	1,751,895
EUR	11,934		16,044	9,558		12,851
JPY	372,256		3,805	646		7
Others			2,309			65
		W	125,631		W	1,764,818

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

As of June 30, 2021, a hypothetical change in exchange rates by 10% would have increased (decreased) the Groups income before income tax as follows:

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 Groups interest-bearing assets are mostly fixed-interest bearing assets, the Groups 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 June 30, 2021, the floating-rate borrowings and debentures of the Group are W 104,043 million and W 339,000 million, respectively, and the Group has entered into interest rate swap agreements for most of floating rate borrowings and debentures to hedge interest rate risk. If the interest rate increases (decreases) 1%p with all other variables held constant, income before income taxes for the six-month period ended June 31, 2021 would change by W 240 million in relation to the floating-rate borrowings that are exposed to interest rate risk.

As of June 30, 2021, the floating-rate long-term payables other are W 1,200,691 million. If the interest rate increases (decreases) 1%p with all other variables held constant, income before income taxes for the six-month ended June 30, 2021 would change by W 6,003 million in relation to the floating-rate long-term payables other that are exposed to interest rate risk.

Financial Risk Management, Continued

(1) Financial risk management, Continued

2) Credit risk, Continued

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 considering the partys 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 and contract assets. 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 Groups 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 June 30, 2021.

3) Liquidity risk

The Groups approach to managing liquidity is to ensure that it will always maintain sufficient cash and cash equivalent balances and have enough liquidity through various committed credit lines. The Group maintains enough liquidity within credit lines through active operating activities.

Contractual maturities of financial liabilities as of June 30, 2021 are as follows:

(In millions of won)	Carrying amount	Contractual cash flows	Less than 1 year	1 - 5 years	More than 5 years
Accounts payable trade	W	304,311	304,311	304,311

(3) Fair value, Continued

1) Fair value and carrying amount of financial assets and liabilities based on fair value hierarchy as of June 30, 2021 and December 31, 2020, are as follows, Continued:

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 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 for 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 June 30, 2021 are as follows:

	Interest rate
Derivative instruments	0.14% ~ 3.90%
Borrowings and debentures	1.15% ~ 3.48%
Long-term payables other	1.37% ~ 2.06%

Notes to the Condensed Separate Interim Financial Statements

For the six-month periods ended June 30, 2021 and 2020

Reporting Entity

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

The Companys common shares and depositary receipts (DRs) are listed on the Stock Market of Korea Exchange, the New York Stock Exchange and the London Stock Exchange. As of June 30, 2021, the Companys total issued shares are held by the following shareholders:

SK Inc.	21,624,120	30.00
National Pension Service	7,205,438	10.00
Institutional investors and other shareholders	41,064,465	56.99
Kakao Co., Ltd.	1,266,620	1.76
Treasury shares	899,500	1.25
	72,060,143	100.00

Basis of Preparation

(1) Statement of compliance

These condensed separate interim financial statements were prepared in accordance with Korean International Financial Reporting Standard (K-IFRS) No. 1034, Interim Financial Reporting, as part of the period covered by the Companys K-IFRS 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, 2020. These condensed separate interim financial statements do not include all of the disclosures required for full annual financial statements.

These condensed interim financial statements are separate interim financial statements prepared in accordance with K-IFRS No. 1027, Separate Financial Statements, 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.

(2) Use of estimates and judgments

1) Critical judgments, assumptions and estimation uncertainties

The preparation of the condensed separate interim financial statements in conformity with K-IFRS 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 condensed separate interim financial statements, the significant judgments made by management in applying the Companys 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, 2020.

Basis of Preparation, Continued

(2) Use of estimates and judgments, Continued

2) Fair value measurement

A number of the Companys accounting policies and disclosures require the measurement of fair values, for both 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 K-IFRS, 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.

Significant Accounting Policies

(1) Except as described below, the accounting policies applied in these interim financial statements are the same as those applied in the Companys separate financial statements as at and for the year ended December 31, 2020. The change in accounting policy will also be reflected in the Companys separate financial statements as at and for the year ending December 31, 2021.

The Company has initially adopted Interest Rate Benchmark Reform Phase 2 Amendments to K-IFRS No. 1109, Financial Instruments , K-IFRS No. 1039, Financial Instrument: Recognition and Measurement, K-IFRS No. 1107, Financial Instruments: Disclosures and K-IFRS No. 1116, Leases from January 1, 2021.

Interest Rate Benchmark Reform Phase 2 Amendments provide exceptions as follows:

when a change required by interest rate benchmark reform occurs to a financial asset or financial liability measured at amortized cost, the Company updates the effective interest rate of the financial asset or financial liability rather than the carry amount and,

when a change required by interest rate benchmark reform occurs to a hedged item and/or hedging instrument, the exception permits the hedge relationship to be continued without interruption.

These amended standards are not expected to have a significant impact on the Companys separate financial statements.

(2) During the annual period ended December 31, 2020, the Company changed its accounting policy by applying agenda decision, Lease Term and Useful Life of Leasehold Improvements (IFRS 16 Leases and IAS 16 Property, Plant and Equipment)November 2019 , published by International Financial Reporting Interpretations Committee (IFRIC) on December 16, 2019. Due to the changes in accounting policies in connection with the IFRIC agenda, the Company restated its comparative financial statements for the six-month period ended June 30, 2020.

The following table summarizes the impacts of the change in accounting policy on the Companys condensed separate interim financial statements.

(2) Changes in the loss allowance on trade and other receivables measured at amortized cost for the six-month periods ended June 30, 2021 and 2020 are as follows:

(In millions of won)	January 1, 2021	Impairment	Write-offs(*)		Collection of receivables previously written- off	June 30, 2021

	W	180,214	17,132	(15,608	)	5,836	187,574

(*) The Company writes off the trade and other receivables that are determined to be uncollectable due to reasons such as termination of operations or bankruptcy.

(3) The Company applies the practical expedient that allows the Company to estimate the loss allowance for accounts 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 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 Companys 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 rating. While the contract assets are under the impairment requirements, no significant credit risk has been identified.

Financial Risk Management

(1) Financial risk management

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

The Companys financial assets consist of cash and cash equivalents, financial instruments, investment securities, accounts receivable trade and others, etc. Financial liabilities consist of accounts payable other, borrowings, debentures, lease liabilities and others.

1) Market risk

(i) Currency risk

The Company is exposed to currency risk mainly on exchange fluctuations 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 June 30, 2021 are as follows:

(In millions of won, thousands of foreign currencies)
Assets			Liabilities
Foreign currencies		Won equivalent	Foreign currencies		Won equivalent
USD	15,146	W	17,115	1,211,552	W	1,369,053
EUR	581		781	4		6
Others			160
		W	18,056		W	1,369,059

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

As of June 30, 2021, a hypothetical change in exchange rates by 10% would have increased (decreased) the Companys income before income taxes as follows:

(In millions of won)	If increased by 10%	If decreased by 10%
USD	W	946	(946	)
EUR		78	(78	)
Others		16	(16	)
	W	1,040	(1,040	)

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 Companys interest-bearing assets are mostly fixed-interest bearing assets, the Companys revenue and operating cash flows from the interest-bearing assets are not influenced by the changes in market interest rates.

The Company performs various analyses 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 June 30, 2021, floating-rate debentures amount to W 339,000 million, and the Company has entered into interest rate swaps to hedge interest rate risk related to the floating-rate debentures. Therefore, income before income taxes for the six-month period ended June 30, 2021 would not have been affected by the changes in interest rates of floating-rate debentures.

As of June 30, 2021, the floating-rate long-term payables other are W 1,200,691 million. If the interest rate increases (decreases) 1%p with all other variables held constant, income before income taxes for the six-month period ended June 30, 2021, would change by W 6,003 million in relation to the floating-rate long-term payables other that are exposed to interest rate risk.

2) Credit risk

The maximum credit exposure as of June 30, 2021 and December 31, 2020 are as follows:

(In millions of won)	June 30, 2021	December 31, 2020
Cash and cash equivalents	W	285,339	329,176

Derivative financial assets		124,355	85,165
	W	3,248,525	3,507,367

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 creditworthiness of each customer or counterparty considering the partys 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 and other. 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 Companys 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 amount of maximum exposure to credit risk of the Company is the carrying amount of financial assets as of June 30, 2021.

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 for 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 June 30, 2021 are as follows:

	Interest rate
Derivative instruments	0.14% ~ 1.65%
Borrowings and debentures	1.15% ~ 1.91%
