Risks Relating to Our Business

Competition may reduce our market share and harm our business, financial condition and results of operations.

We face substantial competition across all of our businesses, including our wireless telecommunications business. We expect competition to intensifyremain intense as a result of the development of new technologies, products and services.services are developed and introduced by us and our competitors. We expect that such trends will continue to put downward pressure on the rates we can charge our subscribers.

Historically, there has been considerable consolidation in the telecommunications industry, resulting in the current competitive landscape comprising three mobile and fixed network operators in the Korean market, us, KT Corporation (“KT”) and LG Uplus Corp. (“LG U+”). Each of our competitors has substantial financial, technical, marketing and other resources to respond to our business offerings. As of December 31, 2021,2023, the collective market share of KT and LG U+ amounted to approximately 55.7%59.3% in terms of number of wireless subscribers (including an aggregate of 11.4%16.3% attributable to mobile virtual network operators (“MVNOs”) that lease KT’s and LG U+’s respective networks). compared to 56.8% (including an aggregate of 13.8% attributable to MVNOs) as of December 31, 2022. Such increase in the collective market share of KT and LG U+ was mainly attributable to an increase in the market share of MVNOs that lease LG U+’s network.

Our competitors for subscriber activations include MVNOs, including MVNOs that lease our networks. MVNOs generally provide rate plans that are relatively cheaper than similar rate plans of the wireless network providers from which they lease their networks, including us. In recent years, a number of new entrants have entered the MVNO business, including affiliates of leading financial institutions in Korea. Some of these new entrants have engaged in aggressive marketing campaigns and promotional discounts while leveraging the brand power of their affiliates as part of their efforts to gain subscribers. Partly as a result of such efforts, the combined market share of MVNOs has increased in recent years from 14.4% as of December 31, 2021 to 16.9% as of December 31, 2022 and 19.2% as of December 31, 2023, in terms of number of subscribers.In addition, other companies may enter the wireless network services market. While new entries into such market have historically required obtaining requisite licenses fromFor example, in January 2024, the MSIT, pursuantGovernment allocated 800 MHz of bandwidth in the 28 GHz spectrum to Stage X, a consortium led by Stage Five, an amendmentMVNO, to the Telecommunications Business Act that went into effect in June

2019, companies meeting certain regulatory criteria may become a network service provider by registering with the MSIT without a separate license requirement. Although such amendment has not yet resulted in any new entries into the Koreanprovide nationwide wireless network services market, it may haveservices. Stage X is required, among other things, to install 6,000 base stations across Korea that use the effect of encouraging new entries in the future.
28 GHz spectrum by 2027.

We believe that ana continued increase in the market share of MVNOs (including through the entrance of new MVNOs, if any) and the entrance of new mobile network operators (including in connection with the allocation of 800 MHz of bandwidth in the 28 GHz spectrum in January 2024 to Stage X), if any, in the wireless telecommunications market may further increase competition in the telecommunications sector, as well as cause downward price pressure on the fees we charge for our services, which, in turn, may have a material adverse effect on our business, financial position and results of operations.

See “— Our business, financial condition and results of operations may be adversely affected if we fail to acquire adequate additional frequency usage rights or use our bandwidth efficiently to accommodate subscriber growth and subscriber usage” and “— Our businesses are subject to various types of Government regulation, and any change in Government policy relating to the telecommunications industry could have an adverse effect on our business, financial condition and results of operations.”

Our fixed-line telephone service competes with KT and LG U+, as well as other providers of voice over Internet protocol (“VoIP”) services. As of December 31, 2021,2023, our market share of the fixed-line telephone and VoIP service market was 15.7% (including the services provided by SK Broadband Co., Ltd. (“SK Broadband”)) in terms of number of subscribers compared to KT with 56.3%54.2% and LG U+ with 19.0%18.7%. In addition, our broadband Internet access, Internet protocol TV (“IPTV”) and cable TV services provided through SK Broadband compete with other providers of such services, including KT, LG U+ and cable companies. Furthermore, our IPTV and cable TV services are facing an increasing level of competition from global operators of online video streaming platforms, such as YouTube, Netflix, Disney Plus and Amazon Video,Apple TV, leading domestic video streaming platforms such as TVING, WatchaaWavve (which is seeking to merge with TVING pursuant to a memorandum of understanding entered into in December 2023), Coupang Play and Wavve,Watcha, and the video services offered by leading domestic online and mobile search and communications platforms including NAVER and Kakao, as such services continue to become increasingly popular to serve as a substitute to traditional television programming. As of December 31, 2021,2023, our market share of the broadband Internet market was 28.7% in terms of number of subscribers compared to KT with 41.2%40.8% and LG U+ with 20.7%21.4%. As of December 31, 2021,2023, our market share of the pay TV market (which includes IPTV, cable TV and satellite TV) was 25.0%26.1% compared to KT with 36.2%36.5% (including its IPTV, cable TV and satellite TV services) and LG U+ with 25.3%24.7% (including its IPTV and cable TV services), and the collective market share of other pay TV providers was 13.4%12.8%.

Recently,

Over the past few years, the Korean fixed-line telecommunications industry has been goinggone through significant consolidation involving major pay television service providers. In April 2020, we completed the merger of Tbroad Co., Ltd., a former leading cable television and other fixed-line telecommunications services provider in Korea, and two of its subsidiaries, Tbroad Dongdaemun Broadcasting Co., Ltd. and Korea Digital Cable Media Center Co. Ltd. (collectively, “Tbroad”), with and into SK Broadband. As a result of the merger and the issuance of SK Broadband’s shares to the former shareholders of Tbroad with an aggregate fair value of Won 862.1 billion as of April 30, 2020, we owned approximately 74.3% of SK Broadband’s total outstanding shares as of December 31, 2021. In the same month, SK Telecom acquired a 55.0% equity interest in Broadband Nowon Co., Ltd. (formerly known as Tbroad Nowon Broadcasting Co., Ltd.), another subsidiary of Tbroad Co., Ltd., for a purchase price of Won 10.4 billionwhich was subsequently merged with and into SK Broadband in cash. As a result ofOctober 2022. Following such transactions (the “Tbroad Merger”), we becameowned approximately 74.4% of SK

Broadband’s total outstanding shares as of December 31, 2023 and were the third-largestsecond-largest pay TV provider in Korea in terms of number of subscribers as of December 31, 2021.2023. In December 2019, LG U+ acquired a majority equity stake in CJ Hello Co., Ltd. and changed the acquired company’s name to LG HelloVision Co., Ltd. (“LG HelloVision”) to collectively become the second-largest pay TV provider in Korea in terms of number of subscribers as of December 31, 2021.. In August 2021, KT acquired HCN Co., Ltd. (“HCN”), a major Korean cable TV service provider, through its subsidiary KT Skylife Co., Ltd. (“KT Skylife”).

Such transactions, as well as further consolidation in the fixed-line telecommunications industry, may result in increased competition, as the entities emerging from such consolidation and other remaining players in the industry may actively pursue expanding or protecting their respective market shares.

Furthermore, the Government has historically enforced regulations on cable TV and IPTV service providers that prohibited them from having a market share of more than

one-third
of the total number of subscribers in the relevant pay TV market on each of their respective platforms. In June 2015, the Government amended the regulation to impose the same limit on the market share of the entire pay TV market, including satellite TV service providers as well. Such amended regulation, however, expired in June 2018. There are bills currently pending in the National Assembly to abolish the previous market share regulations on cable TV and IPTV service providers. It is uncertain whether such bills will be passed.

Continued competition from other wireless and fixed-line telecommunications service providers has also resulted in, and may continue to result in, a substantial level of deactivations among our subscribers. SubscriberA substantial level of subscriber deactivations, or churn, may significantly harm our business, financial condition and results of operations. In 2021,

2023, the monthly churn rate in our wireless telecommunications business ranged from 0.7% to 0.9%, with an average monthly churn rate of 0.8%, which decreased from 1.2% in 2020.
remained unchanged compared to 2022. Intensification of competition in the future may cause our churn rates to increase, which in turn may cause us to increase our marketing expenses as a percentage of sales to attract and retain subscribers.

As we continue to expand our business into areas beyond the traditional wireless and fixed-line telecommunications businesses, we also face competition from major players in the relevant sectors, such as television shopping

(“T-commerce”),
cloud services, data center services, smart factories, metaverse, online commerce and smart factories.television shopping (“T-commerce”). Some of our competitors may have stronger brand recognition, more robust technological capabilities and/or more significant financial resources than us in their respective areas of business.

Our ability to compete successfully in all of the businesses in which we operate will depend on our ability to anticipate and respond to various competitive factors affecting the respective industries, including new services that may be introduced, changes in consumer preferences, economic conditions and discount pricing strategies by competitors.

Inability to successfully implement or adapt our network and technology to meet the continuing technological advancements affecting the wireless telecommunications industry will likely have a material adverse effect on our business, financial condition and results of operations.

The telecommunications industry has been characterized by continual improvementimprovements and advances in technology, and this trend is expected to continue. We and our competitors have continually implemented technology upgrades from our basic code division multiple access (“CDMA”) network to our wideband code division multiple access (“WCDMA”) network, and subsequently to the currently dominant LTE and 5G technologies. Our business could be harmed if we fail to implement, or adapt to, future technological advancements in the telecommunications sector in a timely manner, such as the continued implementation and enhancement of 5G technology and the eventual development and implementation of a successor technology to 5G technology. We launched wireless service plans using the 5G network in April 2019 following the commencement of sales of the first

5G-compatible
smartphones, and we are in the process of further expanding our 5G network coverage. Our 5G network coverage whichcurrently includes all of the major metropolitan and other urban areas, as well as subway lines, in Korea, and we have been expanding our 5G network coverage in rural areas by constructing 5G networks that are shared with other mobile network operators in such areas. We expect to be able to provide full nationwide outdoor terrestrial coverage and substantially complete withinfull nationwide coverage in large buildings by the next several years. end of 2024.KT and LG U+ have also rolled out their respective 5G wireless service plans in

April 2019. The more successful operation of a 5G network or development of improved 5G technology by a competitor, including better market acceptance or network quality of a competitor’s 5G services, could materially and adversely affect our existing wireless telecommunications businesses as well as the returns on future investments we may make in our 5G network or our other businesses.

In addition to introducing new technologies and offerings, we must phase out outdated and unprofitable technologies and services. For example, as of January 2019, we discontinued our wireless broadband Internet access (“WiBro”) services in January 2019 and we also terminated our second generation CDMA wireless services in July 2020. If we are unable to do sointroduce new technologies and offerings on a cost-effective and timely basis, our business, financial condition and results of operations could be adversely affected.

Implementation of new wireless technology and enhancement of existing wireless technology have required, and may continue to require, significant capital and other expenditures, which we may not recoup.

We have made, and intend to continue to make, capital investments to develop, launch and enhance our wireless service. In 2021, 20202023, 2022 and 2019,2021, we spent Won 1,850.91,380.6 billion, Won 1,878.61,833.4 billion and 2,514.3Won 1,850.9 billion, respectively, in capital expenditures to build and enhance our wireless networks. Our continued implementation and expansion of 5G services, which use a higher frequency spectrum than our LTE services, will require additional base stations (which are also commonly referred to as “cell sites”) and other infrastructure, which may result in an increase in our capital expenditures in the future.

We also plan to make further capital investments related to our wireless services in the future, including services that can potentially leverage our 5G network.network and enhance the service quality of our 5G network, including through the development and application of AI technology. In addition, we plan to continue expanding and maintaining our 5G network as described above, while also maintaining our LTE network, which we expect will continue to be used by a significant portion of our subscriber base duringin the near future, as wedespite the ongoing expansion of the 5G network and our competitors further expand 5G networks and services andgradual migration of wireless service users continue to migrate to the 5G network over time.
Our wireless technology-related investment plans are subject to change, and will depend, in part, on market demand for 5G and LTE services, the competitive landscape for provision of such services and the development of competing technologies. There may not be

Table of Contents
sufficient demand for services based on our latest wireless technologies, as a result of competition or otherwise, to permit us to recoup or profit from our wireless technology-related capital investments.

Our businesses are subject to various types of Government regulation, and any change in Government policy relating to the telecommunications industry could have an adverse effect on our business, financial condition and results of operations.

Our businesses are generally subject to governmental supervision and various types of regulation.

Rate Regulation.

The Government has periodically reviewed the rates charged by wireless telecommunications service providers and has, from time to time, released public policy guidelines or suggested rate reductions. Although these guidelines or suggestions were not binding, we have implemented some rate reductions in response to them. For example, under the MDDIA,Mobile Device Distribution Improvement Act (“MDDIA”), wireless telecommunications service providers are obliged to provide certain benefits, such as discounted rates, to subscribers who subscribe to their service without receiving subsidies. In June 2017, the State Affairs Planning Advisory Committee of Korea announced that it would encourage wireless telecommunications service providers, including us, to increase the applicable discount rate offered to subscribers from 20% to 25%, which we adopted in September 2017, and to offer additional discounts to low income customers, including those on government welfare programs and senior citizen recipients of the basic pension, which we implemented in December 2017 and July 2018, respectively. While the Government indicated in January 2024 that it will seek to abolish the MDDIA in order to encourage wireless service providers to offer more differentiated customer benefits to consumers, it has also suggested that such discounted rates may be retained through a related amendment to the Telecommunications Business Act. In connection with such policy objectives, the Government amended the Enforcement Decree of the MDDIA in March 2024, pursuant to which wireless telecommunications service providers may provide more liberal subsidies to subscribers that are switching their wireless telecommunications providers based on certain criteria specified by the KCC, including

7


the expected profits to the wireless telecommunications service providers and subscribers’ costs of switching wireless telecommunications service providers. See “Item 4.B. Business Overview — Law and Regulation — Rate Regulation” and “Item 5.A. Operating Results — Overview — Rate Regulations.” Such discounts have contributed to a general decrease in the monthly revenue per subscriber of our wireless telecommunications services. See “Item 5.A. Operating Results — Overview — Decrease in Monthly Revenue per Subscriber.” In July 2022, the MSIT requested wireless telecommunications service providers, including us, to introduce additional mid-tier 5G rate plans to provide 5G subscribers with more diverse and affordable rate plans that better meet their data usage patterns. We have since introduced several types of such new plans in 2022 and 2023. In November 2023, the MSIT requested wireless telecommunications service providers, including us, to provide 5G smartphone users with the option to subscribe to LTE plans, which we implemented in the same month. In addition, in January 2024, the MSIT requested wireless telecommunications service providers, including us, to introduce low-tier 5G rate plans priced under Won 40,000 per month, which we implemented in March 2024. The Government may suggest other policy initiatives relating to rate plans of wireless telecommunications service providers in the future including more affordable subscription plans for 5G wireless services for different customer segments such as those with lower volumes of data usage, and any further changes to our rate plans we make in response to such suggestion may adversely affect our profitability and results of operations.

Technology Standards.

The Government also plays an active role in setting the timetable and quality standards for the adoption and implementation of new technologies to be used by telecommunications operators in Korea. For example, the Government provided such guidance in connection with the introduction of LTE and 5G technologies in the past. The Government may provide similar guidance or recommendations in connection with the adoption and implementation of technologies to be used in future telecommunications services, and it is possible that adherence to such guidance or recommendations promoted by the Government in the future may not provide us with the best commercial returns.

Frequency Allocation.

The Government sets the policies regarding the use of frequencies and allocates the spectrum of frequencies used for wireless telecommunications. See “Item 4.B. Business Overview — Law and Regulation — Frequency Allocation.” The reallocation of the spectrum to our existing competitors or a new entrant to the wireless telecommunications business could increase competition among wireless telecommunications service providers, which may have an adverse effect on our business, financial condition and results of operations.
See “— Our business, financial condition and results of operations may be adversely affected if we fail to acquire adequate additional frequency usage rights or use our bandwidth efficiently to accommodate subscriber growth and subscriber usage.”

MVNOs.

Pursuant to the Telecommunications Business Act, certain wireless telecommunications service providers designated by the MSIT, which included only us, were required to lease their networks or allow use of their networks (collectively, a “wholesale lease”) toby other network service providers, such as an MVNO, that have requested such a wholesale lease in order to provide their own services using the leased networks until September 2022. While such regulatory requirement expired in September 2022, we have continued to comply with such requirement pending future regulatory development, and in December 2023, a bill indefinitely extending such requirement was passed by the National Assembly. Currently, 1314 MVNOs provide wireless telecommunications services using the networks leased from us. We believe that leasing a portion of our bandwidth capacity to an MVNO impairs our ability to use our bandwidth in ways that would generate maximum revenues and strengthens our MVNO competitors by granting them access and lowering their costs to enter into and operate in our markets. Accordingly, our profitability has been, and may continue to be, adversely affected.

Interconnection.

Our wireless telecommunications services depend, in part, on our interconnection arrangements with domestic and international fixed-line and other wireless networks. Our interconnection arrangements, including the interconnection rates we pay and interconnection rates we charge, affect our revenues and operating results. The MSIT determines the basic framework for interconnection arrangements, including
7

Table of Contents
policies relating to interconnection rates in Korea. The KCC, which determined such basic framework under the previous Government, changed theSuch basic framework for interconnection arrangements has been changed several times. Wetimes in the past, and we cannot assure you that we will not be adversely affected by the MSIT’s interconnection policies and future changes to such policies. See “Item 4.B. Business Overview — Interconnection — Domestic Calls.”

Regulatory Action.

The MSIT may revoke our licenses or suspend any of our businesses if we fail to comply with its rules, regulations and corrective orders, including the rules restricting beneficial ownership and control or any violation of the conditions of our licenses. Alternatively, in lieu of suspension of our business, the MSIT or, depending on the subject matter of the violation, the KCC may levy a monetary penalty of up to 3.0% of the average of our annual revenue for the preceding three fiscal years. For information about the penalties imposed on us for violating Governmental regulations, see “Item 8.A. Consolidated Statements and Other Financial Information — Legal Proceedings — KCC Proceedings.” Such penalties, which may include the revocation of cellular licenses, suspension of business or imposition of monetary penalties by the KCC, could have a material adverse effect on our business. We believe that we are currently in compliance with the material terms of all of our cellular licenses.

In addition, the Fair Trade Act provides for various regulations and restrictions enforced by the Korea Fair Trade Commission (the “KFTC”) to prohibit or restrict actions that impede competition and fair trade. From time to time, we have been, and may in the future be, subject to investigations by the KFTC relating to potential violations of such laws and regulations. See “Item 8.A. — Consolidated Statements and Other Financial Information — Legal Proceedings — KFTC Proceedings.” Any future determination by the KFTC that we have engaged in transactions that violate the fair trade laws and regulations may result in fines or other punitive measures and may have a material adverse effect on our business.

We are subject to additional regulations as a result of our dominant market position in the wireless telecommunications sector, which could harm our ability to compete effectively.

The Government endeavors to promote competition in the Korean telecommunications markets through measures designed to prevent a dominant service provider from exercising its market power and deterring the emergence and development of viable competitors. We have been designated by the MSIT as the “dominant network service provider” in respect of our wireless telecommunications business. As such, we are subject to additional regulations to which certain of our competitors are not subject. For example, the MSIT has fifteen days to object to any new rates and terms of service reported by us. See “Item 4.B. Business Overview — Law and Regulation — Rate Regulation.”

The MSIT could also require us to charge higher usage rates than our competitors for future services or to take certain actions earlier than our competitors, as when the KCC required us to introduce number portability earlier than our competitors, KT and LG U+.

We also qualify as a “market-dominating business entity” under the Fair Trade Act, which subjects us to additional regulations and we are prohibited from engaging in any act of abusing our position as a market-dominating entity. See “Item 4.B. Business Overview — Law and Regulation — Competition Regulation.” The additional regulations to which we are subject hashave affected our competitiveness in the past and may materially hurt our profitability and impede our ability to compete effectively against our competitors in the future.

The ongoing global pandemic

Occurrences of a new strain of coronavirus

(“COVID-19”)
andwidespread infectious diseases, including any possible recurrence of other types of widespread infectious diseasesCOVID-19, may materially and adversely affect our business, financial condition and results of operations.

COVID-19,

an infectious disease caused by severe acute respiratory syndrome coronavirus 2, that was first reported to have been transmitted to humansdeclared a “pandemic” by the World Health Organization in late 2019 and has since spread globally, has materially and adversely affectedMarch 2020. In recent years, the global economyoutbreak of COVID-19 had led to global economic and caused significant volatilityfinancial disruptions and uncertainty in global financial marketshad from time to date as well astime disrupted our business operations. The World Health Organization declared
COVID-19
as a pandemic in March 2020. We have implemented remote work arrangements for most of our employees at our headquarters and certain other locations from time to time in light of the Government’s recommendation for social distancing. In addition, the travel restrictions imposed by governments in response to the
COVID-19
pandemic has resulted in a decrease in revenue from roaming services, and the pandemic also contributed to lower customer demand for new wireless devices, resulting in a decrease in our wireless device sales revenue.
While we do not believe that the
COVID-19
pandemic and the resulting temporary remote work arrangements or such decreases in revenue havehas had a material adverse impact on our overall business to date,
a prolonged outbreakfuture exacerbation of
the COVID-19
pandemic or other types of widespread infectious diseases may result in further disruption in the normal operations of our business, including implementation of further work arrangements requiring employees to work remotely and/or temporary closures of our facilities, which may, among others, leadbusiness.

We are subject to a reduction in labor productivity, as well as further decrease in revenue from roaming services or wireless device sales.

Other risks, associated with a prolonged outbreak ofincluding but not limited to:

COVID-19
or other types of widespread infectious diseases include:

an increase in unemployment among, and/or a decrease in disposable income of, our customers, who may not be able to meet payment obligations or otherwise choose to decrease their spending levels, which in turn may decrease demand for some of our products and services or cause an increase in delinquent subscriber accounts;

a slowdown in the rate of subscriber migration to our 5G service, which generally entails higher-priced subscription plans and wireless devices;

disruptions in operations, and/or a decrease in the demand for products and services, of our corporate customers, which in turn may decrease such customers’ demand for our services and products;

service disruptions, outages and performance problems due to capacity constraints caused by an overwhelming number of people accessing our services simultaneously;

disruptions in the supply of mobile handsets or telecommunications equipment from our vendors (or components of such mobile handsets and equipment such as semiconductors) as well as in the installation of our network infrastructure;

continued instability in global and Korean financial markets, which may adversely affect our ability to meet capital funding needs on a timely and cost-effective basis;

a decrease in the fair value of our investments in companies that may be adversely affected by the pandemic; and

depreciation of the Won against major foreign currencies, which in turn may increase the cost of imported equipment necessary for expansion and enhancement of our telecommunications infrastructure.

It is not possible to predict the duration or full magnitude of harm from
COVID-19.

In the event that

a future recurrence of COVID-19
or other types of widespread infectious diseases cannot be effectively and timely contained, our business, financial condition and results of operations may be adversely affected.

We may fail to successfully complete, integrate or realize the anticipated benefits of our new acquisitions, joint ventures or other strategic alternatives or corporate reorganizations, including the

Spin-off,
and such transactions may negatively impact our business.

We continue to seek opportunities to develop new businesses that we believe are complementary to our existing product and service portfolio and expand our global business through selective acquisitions. We also continue to seek ways to optimize our corporate structure to maximize the value of our traditional businesses on the one hand and newly developed businesses on the other hand. Accordingly, we are often engaged in evaluating potential transactions and other strategic alternatives as well as corporate reorganizations, some of which may be significant in size.

For example, we completed the Tbroad Merger in April 2020, andfollowing which we became the third-largestsecond-largest pay TV provider in Korea in terms of number of subscribers as of December 31, 2020. In addition,2023. Moreover, in June 2019, we acquired a 34.6% interest in Incross Co., Ltd. (“Incross”), a digital advertising company, for an aggregate purchase price of Won 53.7 billion, in light of potential synergies with our media and commerce businesses. Furthermore,February 2022, in order to strengthen our security businessonline distribution capabilities and explore potential synergies with our wireless and fixed-line business portfolio,other businesses in the ICT sector, we acquiredindirectly re-acquired a 55.0% interest in Life & Security Holdings Co., Ltd. (“LSH”), which owned 100% of ADT CAPS Co., Ltd. (“Former ADT CAPS”), a leading Korean physical security service company, and two sister companies, CAPSTEC Co., Ltd. and ADT SECURITY Co., Ltd. (which subsequently merged with and into Former ADT CAPS), for Won 696.7 billion in October 2018; a 100%100.0% equity interest in SK Infosecm&service Co., Ltd.

We have also pursued other strategic alternatives, such as forming a strategic alliance in October 2019 with Kakao Corp. (“Kakao”), a Korean Internet company and the operator of Korea’s most popular mobile messaging application, to collaborate in the ICT sector through the sale of 1,266,620 of our treasury shares to Kakao, representing a 1.6% interest, for approximately Won 300.0 billion and a concurrent issuance by Kakao of 2,177,401 of its shares, representing a 2.5% interest, to us for approximately Won 302.3 billion.

In addition, in September 2019,July 2022, we entered into a strategic alliance with Hana Financial Group Inc. (“Hana Financial Group”), a leading financial holding company in furtheranceKorea with subsidiaries having significant presences in commercial banking, credit card business, securities brokerage and insurance, among others, to seek synergies through convergence between finance and ICT technology. As part of such strategic alliance, we transferred the entirety of our efforts15.0% interest in HanaCard Co., Ltd. (“HanaCard”), a leading credit card company in Korea and a subsidiary of Hana Financial Group, for Won 330.0 billion in July 2022 and acquired 8,630,949 shares of Hana Financial Group (representing a 2.9% interest) for Won 330.0 billion between July and November 2022, and HanaCard acquired 1,307,471 common shares of us (representing a 0.6% interest) for Won 68.4 billion between July and September 2022.

In order to enhancepursue enhancement of shareholder value and acceleration of growth of the competitivenessSpin-off Businesses, we effected the Spin-off in November 2021. Following the Spin-off, we have become primarily focused on our core wireless and fixed-line telecommunications businesses, as our equity interests in the Spin-off Portfolio Companies (including our interest in, among others, SK Hynix, SK shieldus Co., Ltd. (a leading provider of our media businessphysical security, cybersecurity and to promote its future growth, we acquired a minority equity stakeconverged security services in Korea), Eleven Street (an e-commerce platform in Korea), T map Mobility Co., Ltd. (a leading provider of mobility services in Korea) and Content Wavve Co., Ltd. (formerly known(which operates Wavve, a leading online contents platform in Korea)) comprising our previous semiconductor and new ICT businesses were transferred to SK Square pursuant to the Spin-off. Our business operations relating to the Spin-off Businesses have been accounted for as Contentdiscontinued operations in our consolidated financial statements for the years ended December 31, 2023, 2022 and 2021 included elsewhere in this annual report.

In line with our strategic emphasis on AI technology, we announced our updated vision of transforming into an “AI Company” that combines AI technology with connectivity technologies of our core telecommunications business as well as the underlying technologies of our other new growth businesses in November 2022 and our “AI Pyramid” strategy in September 2023, which focuses on the three key aspects of (i) developing and expanding our AI infrastructure, (ii) applying AI technology to innovate our existing core business lines and promote the growth of our new growth businesses, and (iii) developing and expanding innovative AI services. See “Item 4.B. Business Overview — Our Business Strategy.” We have also been collaborating with leading Korean AI technology companies as well as other global telecommunications companies in order to accelerate our ongoing transformation to become an AI Company, including by forming the Global Telco AI Alliance Platform Inc.(the “GTAA”) (“Content Wavve”),in July 2023 with Deutsche Telecom of Germany, e& of the United Arab Emirates and Singtel of Singapore, which was later joined by Softbank of Japan in February 2024. The members of the GTAA have agreed to establish a joint venture established bydedicated to the three major terrestrial broadcastersdevelopment of large-language models that are specifically tailored to the needs of telecommunications companies, and also seek business opportunities in Korea that operated the mobile

(“OTT”) service “POOQ,” by investing Won 90.9 billionAI-related business areas. In addition, we made a minority equity investment of US$100 million in cashAnthropic, a generative AI technology company based in San Francisco, in August 2023. We are working with Anthropic and transferring our former mobile OTT service business “oksusu”other technology companies to Content Wavve. Content Wavve combined oksusu and POOQ to launchjointly develop a new integrated mobile OTT service “wavve” in September 2019. multilingual large-language model customized for telecommunications companies.

For a more detailed description of our recent investments in new businesses, see “Item 5.B. Liquidity and Capital Resources — Capital Requirements — Investments in New Growth Businesses.”

Furthermore, in December 2020, we spun off our mobility business into a new wholly-owned subsidiary, T map Mobility Co., Ltd. (“T Map Mobility”), in order to enhance its competitiveness and promote its future growth, and we have also formed a strategic partnership with Uber Technologies, Inc. (“Uber”) pursuant to which Uber has invested approximately US$50 million in T Map Mobility and approximately US$100 million in UT LLC, a joint venture formed in April 2021 between T Map Mobility and Uber. In April 2021, we launched through UT LLC a taxi hailing service that integrated our affiliated taxi driver network and mapping and AI technologies with Uber’s ride hailing technology.
In order to pursue enhancement of shareholder value and acceleration of growth of the
Spun-off
Businesses, we effected the
Spin-off
in November 2021. Following the
Spin-off,
we have become primarily focused on our core wireless and fixed-line telecommunications businesses, as our equity interests in the
Spin-off
Portfolio Companies (including our interest in, among others, SK Hynix, SK shieldus, Eleven Street, T Map Mobility, Incross, Content Wavve and id Quantique) comprising our previous semiconductor and new ICT businesses were transferred to SK Square pursuant to the
Spin-off.
Our business operations relating to the
Spin-off
Businesses have been accounted for as discontinued operations in our consolidated financial statements as of December 31, 2021 and for the years ended December 31, 2019, 2020 and 2021 included elsewhere in this annual report.
More recently, in January 2022, we spun off our
AI-enabled
semiconductor business into a new subsidiary, Sapeon Inc. (“Sapeon”), in which we hold a majority equity interest and each of SK Square and SK Hynix holds a minority equity interest. Through Sapeon, we expect to actively collaborate with SK Square and SK Hynix to develop and commercialize next-generation
AI-enabled
semiconductors for applicable-specific uses. Furthermore, in February 2022, we unveiled our new vision entitled “SKT 2.0,” pursuant to which we announced our plan to reorganize our operations into five major business groups, comprising (i) wireless and fixed-line telecommunications, (ii) media (consisting of broadcast and advertising platform, content and
T-commerce
businesses), (iii) enterprise (consisting of data center, cloud and artificial intelligence of things (“AIoT”)), (iv) “AIVERSE” (consisting of subscription, metaverse and AI agent businesses) and (v) “Connected Intelligence” (consisting of future technology areas such as urban air mobility (“UAM”) and autonomous driving). By
re-defining
the areas of our business focus and optimizing our customer groups, services and technology for each business group, we intend to pursue the maximization of our overall growth and enterprise value.

While we are hoping to benefit from a range of synergies and efficiencies from the

Spin-off
and our other recent or future acquisitions and corporate reorganizations as well as develop new businesses, we may not be able to successfully complete or integrate such acquisitions, new businesses or reorganized entities and may fail to realize the expected benefits in the near term, or at all. For example, in June 2019, we disposed of our entire interest in our consolidated subsidiaries Shopkick Management Company, Inc. (“SMC”) and Shopkick, Inc. (“Shopkick”), a wholly-owned subsidiary of SMC which operates “shopkick,” a mobile reward points-based
in-store

application, which we had acquired in October 2014, following a prolonged period of unprofitability of the shopkick business. Previously in 2018, we also recognized Won 153.4 billion and Won 52.4 billion of impairment losses for goodwill and intangible assets, respectively, in connection with Shopkick. In addition, when we enter into new businesses with partners through joint ventures or other strategic alliances, we and those partners may have disagreements with respect to strategic directions or other aspects of business, or may otherwise be unable to coordinate or cooperate with each other, any of which could materially and adversely affect our operations in such businesses. Our business may be negatively impacted if we fail to successfully integrate or realize the anticipated benefits of such transactions.

Due to the existing high penetration rate of wireless telecommunications services in Korea, we are unlikely to maintain our subscriber growth rate, which could adversely affect our business, financial condition and results of operations.

According to data published by the MSIT and the historical population data published by the Ministry of the Interior and Safety, the penetration rate for the Korean wireless telecommunications industry as of December 31, 20212023 was approximately 139.3%161.3%, which was relatively high compared to many industrialized countries. Therefore, we expect that the penetration rate for wireless telecommunications service in Korea will remain relatively stable. As a result of the already high penetration rate in Korea for wireless telecommunications services coupled with our leading market share, we expect our subscriber growth rate to decrease.

Slowed growth in the penetration rate without a commensurate increase in revenues through the introduction of new services and

11


increased use of our services by existing subscribers would likely have a material adverse effect on our business, financial condition and results of operations.

Our business, financial condition and results of operations may be adversely affected if we fail to acquire adequate additional frequency usage rights or use our bandwidth efficiently to accommodate subscriber growth and subscriber usage.

One of the principal limitations on a wireless network’s subscriber capacity is the amount of frequency spectrum available for use by the network. We have acquired a number of frequency usage rights to secure bandwidth capacity to provide our broad range of services, for which we typically make an initial payment as well as pay usage fees during the license period. We made frequency usage right fee payments of Won 102.5 billion in 2023, Won 103.9 billion in 2022 and Won 120.8 billion in 2021, Won 136.6 billion in 2020 and Won 133.1 billion in 2019.2021. For more information regarding the various bandwidths that we use and the usage right fees for such bandwidths, see “Item 4.B. Business Overview — Law and Regulation — Frequency Allocation,” “Item 5.B. Liquidity and Capital Resources — Capital Requirements — Capital Expenditures” and note 17 of the notes to our consolidated financial statements.

The growth of our wireless data businesses has been a significant factor in the increased utilization of our bandwidth, since wireless data applications are generally more bandwidth-intensive than voice services. In particular, the increasingcontinued increase in popularity of smartphones and data intensive applications among smartphone users has been a major factor for the high utilization of our bandwidth in recent years. Although such trend has been offset in part by the implementation of new technologies that enable more efficient usage of our bandwidth, we expect that the current trend of increased data transmission use by our subscribers will continue to accelerate in the near future as more subscribers migrate to our 5G network and the volume and sophistication of the multimedia content we offer through our wireless data services continue to grow in the 5G environment.

While we believe that we can address the capacity constraint issue through system upgrades and efficient allocation of bandwidth, inability to address such capacity constraints in a timely manner may adversely affect our business, financial condition and results of operations. In the event we are unable to maintain sufficient bandwidth capacity, our subscribers may perceive a general slowdown of wireless telecommunications services. Growth of our wireless telecommunications business will depend in part upon our ability to effectively manage our bandwidth capacity and to implement efficiently and in a timely manner new bandwidth-efficient technologies if they become available. We cannot assure you that bandwidth constraints will not adversely affect the growth of our wireless telecommunications business.

In November 2020,2021, the MSIT announced plans to reallocatereallocated a total of 310 MHz of frequency bandwidths whose usage terms were due to expire in 2021 to KT, LG U+ and us, 95 MHz (in the 800 MHz, 2.1 GHz and 2.6 GHz spectrums) of which was allocated to us in 2021.

Liquidity and Capital Resources — Capital Requirements.” In December 2022, citing the lack of progress made to date with respect to the implementation of 5G infrastructure for our use of the 28 GHz spectrum (800 MHz of bandwidth which was allocated to us in December 2018 for a period of five years until November 2023), the MSIT reduced the duration of our license for the use of such bandwidth by six months and asked us to install 15,000 base stations that use the 28 GHz spectrum by the end of May 2023, which we were not able to do within the Government’s requested timetable. While we do not believe that the loss of such allocated bandwidth have had or will have a material adverse effect on our business, we cannot assure you that we will be able to reacquire such bandwidth in the future or that the failure to reacquire such bandwidth will not adversely affect our future prospects. Furthermore, in December 2022, the Government cancelled the allocations of bandwidth in the 28 GHz spectrum that had been provided to KT and LG U+, also citing the lack of progress made by these companies. In January 2024, the Government allocated 800 MHz of bandwidth in the 28 GHz spectrum to Stage X to provide nationwide wireless network services. Stage X is required, among other things, to install 6,000 base stations across Korea that use the 28 GHz spectrum by 2027.

We may be required to pay a substantial amount to acquire additional bandwidth capacity in the future in order to meet increasing bandwidth demand or renew the rights to use our existing bandwidth, and we may not be successful in acquiring the necessary bandwidth to meet such demand at commercially attractive terms or at all, which may adversely affect our business, financial condition and results of operations.

We rely on key technology professionals and senior management, and the loss of the services of any such personnel or the inability to attract and retain them may negatively affect our business.

Our success depends to a significant extent on the continued service of our research and development and engineering personnel, and our ability to continue to attract, retain and motivate qualified technology professionals including researchers and engineers. In particular, our focus on leading the market in introducing new services has meant that we must aggressively recruit technology professionals with expertise in cutting-edge technologies. Such employees are in high demand, and we devote significant resources to identifying, hiring, training, successfully integrating and retaining these employees. Competition for these individuals could cause us to offer higher compensation and other benefits to attract and retain them. We also depend on the services of experienced key senior management, and if we lose their services, it would be difficult to find and integrate replacement personnel in a timely manner, or at all.

The loss of the services of any of our key technology professionals or senior management without adequate replacement, or the inability to attract new qualified personnel, would have a material adverse effect on our results of operations.

We need to observe certain financial and other covenants under the terms of our debt instruments, the failure to comply with which would put us in default under those instruments.

Certain of our debt instruments contain financial and other covenants with which we are required to comply on an annual and semi-annual basis. The financial covenants with respect to SK Telecom’s debt instruments include, but are not limited to, a maximum net

debt-to-EBITDA
ratio of 3.50 and a minimum
EBITDA-to-total
interest expense ratio of 4.00, each as determined on a separate financial statement basis.
The debt arrangements also contain negative pledge provisions limiting our ability to provide liens on our assets as well as cross-default and cross-acceleration clauses, which give related creditors the right to accelerate the amounts due under such debt if an event of default or acceleration has occurred with respect to our existing or future indebtedness, or if any material part of our indebtedness or indebtedness of our subsidiaries is capable of being declared payable before the stated maturity date. In addition, such covenants restrict our ability to raise future debt financing.

If we breach our financial or other covenants, our financial condition will be adversely affected to the extent we are not able to cure such breaches or repay the relevant debt.

We may have to make further financing arrangements to meet our capital expenditure requirements and debt payment obligations.

We have had, and expect to continue to have, significant capital expenditure requirements as we continue to build out, maintain and upgrade our networks and invest in businesses that complement our wireless and fixed-line telecommunications businesses. We spent Won 2,915.92,973.9 billion for capital expenditures in 2021.

2023.We currently expect to spend a similar amount for capital expenditures in 20222024 compared to 20212023 for a range of projects, including investments to further expand and improve our 5G network, investments to maintain our LTE network and
LTE-A
related services, investments to improve and expand our
Wi-Fi
network, investments to develop our IoT solutions and platform services business portfolio, including AI solutions, investments in data infrastructure, investments in further research and development of 5G technology, investments in businesses that can potentially leverage our 5G network, and investments in funding for
mid-
to long-term research and development projects. Such projects as well asalso include other initiatives primarily related to the development of new growth businesses as well as initiatives related toand our ongoing businesses in the ordinary course.course, in each case with an emphasis on incorporating AI technology into our various existing and new business areas. In November 2020,2021, the MSIT announced plans to reallocatereallocated a total of 310 MHz of frequency bandwidths whose usage terms were due to expire in 2021 to KT, LG U+ and us, 95 MHz (in the 800 MHz, 2.1 GHz and 2.6 GHz spectrums) of which was allocated to us in 2021.us. See “Item 5.B. Liquidity and Capital Resources — Capital Requirements.”We would be required to spend additional amounts on capital expenditures in connection with buildingour continued efforts to build out our networks on such reallocated bandwidths. We may increase, reduce or suspend our planned capital expenditures for 2024 or

Table

change the timing and area of Contents

our capital expenditure spending from the estimates described above in response to market conditions or for other reasons. We may also make additional capital expenditures and other investments beyond our currently anticipated level as opportunities arise, including in relation to any acquisitions of additional frequency usage rights or execution of additional AI-related investments.

In particular, we continue to make significant capital investments to expand and upgrade our wireless networks in response to growing bandwidth demand by our subscribers. Bandwidth usage by our subscribers has rapidly increased in recent years primarily due to the increasing number of data intensive mobile applications and use of such applications by smartphone users. If heavy usage of bandwidth-intensive services grows beyond our current expectations, we may need to invest more capital than is currently anticipated to expand the bandwidth capacity of our networks or our customers may have aexperience suboptimal experienceperformance when using our services. Any of these events could adversely affect our competitive position and have a material adverse effect on our business, financial condition and results of operations. For a more detailed discussion of our capital expenditure plans and a discussion of other factors that may affect our future capital expenditures, see “Item 5.B. Liquidity and Capital Resources — Capital Requirements — Capital Expenditures.”

As of December 31, 2021,2023, we had Won 2,461.02,707.2 billion in contractual payment obligations (excluding short-term leases and leases of low-value assets) due in 2022,2024, which mostly involved repayment of debt obligations and payments related to lease liabilities and other short-term leases and leases of

low-value
assets and payments related to frequency licenses. See “Item 5.B. Liquidity and Capital Resources — Contractual Obligations and Commitments.”

We have not arranged firm financing for all of our current or future capital expenditure plans and contractual payment obligations. We have, in the past, obtained funds for our proposed capital expenditure and payment obligations from various sources, including our cash flow from operations as well as from financings, primarily debt and equity financings. Any material adverse change in our operational or financial condition could impact our ability to fund our capital expenditure plans and contractual payment obligations. Volatile financial market conditions and an increasing interest rate environment may also curtail our ability to obtain adequate funding.funding and/or increase our cost of borrowings, which would have an adverse effect on our liquidity and financial position. Inability to fund such capital expenditure requirements may have a material adverse effect on our business, financial condition and results of operations. In addition, although we currently anticipate that the capital expenditure levels estimated by us will be adequate to meet our business needs, such estimates may need to be adjusted based on developments in technology and markets. Failure to meet any such increased expenditure requirements or to obtain adequate financing for such requirements on terms acceptable to us, or at all, may have a material adverse effect on our business, financial condition and results of operations.

Termination or impairment of our relationship with a small number of key suppliers for network equipment and for leased lines could adversely affect our business, financial condition and results of operations.

We purchase wireless network equipment from a small number of suppliers. To date, we have purchased substantially all of the equipment for our networks from Samsung Electronics Co., Ltd. (“Samsung Electronics”),

Ericsson-LG
Co., Ltd.
(“Ericsson-LG”)
and Nokia Corporation (“Nokia”). We believeIn addition, we purchase a substantial majority of our wireless devices from Samsung Electronics currently manufactures more than half of the wireless handsets sold to our subscribers. and Apple.Although other manufacturers sell the equipment we require, sourcing such equipment from other manufacturers could result in unanticipated costs in the maintenance and enhancement of our wireless networks. Inability to obtain the equipment needed for our networks in a timely manner may have an adverse effect on our business, financial condition and results of operations.

We cannot assure you that we will be able to continue to obtain the necessary equipment from one or more of our suppliers. Any discontinuation or interruption in the availability of equipment from our suppliers for any reason could have an adverse effect on our business, financial condition and results of operations. In addition, inability to lease adequate lines at commercially reasonable rates may impact the quality of the services we offer and may also damage our reputation and our business.

14


Our business relies on technology developed by us, and our business will suffer if we are unable to protect our proprietary rights.

We own numerous patents and trademarks worldwide, and have applications for patents pending in many countries. In addition to active research and development efforts, our success depends in part on our ability to obtain patents and other intellectual property rights covering our services.

We may be required to defend against charges of infringement of patent or other proprietary rights of third parties. Although we have not experienced any significant patent or other intellectual property disputes, we cannot

13

Table of Contents
be certain that any significant patent or other intellectual property disputes will not occur in the future. Defending our patent and other proprietary rights could require us to incur substantial expense and to divert significant resources of our technical and management personnel, and could result in our loss of rights to employ certain technologies to provide services.

Malicious and abusive Internet practices could impair our services and we may be subject to significant legal and financial exposure, damage to our reputation and a loss of confidence of our customers.

Our business involves the storage and transmission of large amounts of confidential information, and cybersecurity breaches expose us to a risk of loss of this information, which may lead to improper use or disclosure of such information, ensuing potential liability and litigation, any of which could harm our reputation and adversely affect our business.

We maintain a comprehensive process for assessing, identifying and managing material risks from cybersecurity threats as part of our overall risk management system and processes. See “Item 16K. Cybersecurity.” Our cybersecurity measures may also be breached due to employee error, malfeasance or otherwise. Instituting appropriate access controls and safeguards across all of our information technology infrastructure is challenging. Furthermore, outside parties may attempt to fraudulently induce employees to disclose sensitive information in order to gain access to our data or our customers’ data or accounts, or may otherwise obtain access to such data or accounts. Because the techniques used to obtain unauthorized access, disable or degrade service or sabotage systems change frequently and often are not recognized until attacks are launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. While we have experienced minor isolated cybersecurity incidents in the past, we do not believe that any such incidents had a material adverse effect on our business, financial condition or results of operations. If an actual or perceived breach of our cybersecurity of a material nature occurs or the market perception of the effectiveness of our cybersecurity measures is materially harmed, we may incur significant legal and financial exposure, including legal claims and regulatory fines and penalties, damage to our reputation and a loss of confidence of our customers, which could have an adverse effect on our business, financial condition and results of operations.

In addition, our wireless and fixed-line subscribers utilize our network to access the Internet and, as a consequence, we or they may become victim to common malicious and abusive Internet activities, such as unsolicited mass advertising (

i.e.
, “spam”), hacking of personal information, distributed
denial-of-service
attacks and dissemination of viruses, worms and other destructive or disruptive software. These activities could have adverse consequences on our network and our customers, including degradation of service, excessive call volume to call centers and damage to our or our customers’ equipment and data. Significant incidents could lead to customer dissatisfaction and, ultimately, loss of customers or revenue, in addition to increased costs to us to service our customers and protect our network. Any significant loss of our subscribers or revenue due to incidents of malicious and abusive Internet practices or significant increase in costs of serving those subscribers could adversely affect our business, financial condition and results of operations.

Labor disputes may disrupt our operations.

Although we have never experienced any significant labor disputes, there can be no assurance that we will not experience labor disputes in the future, including protests and strikes, which could have an adverse effect on our business, financial condition and results of operations.

15


Every two years, the union and management negotiate and enter into a new collective bargaining agreement that has a

two-year
duration, which is focused on employee benefits and welfare. Employee wages are separately negotiated on an annual basis. Although we consider our relationship with our employees to be good, there can be no assurance that we will be able to maintain such a working relationship with our employees and will not experience labor disputes resulting from disagreements with the labor union in the future.

Concerns that radio frequency emissions may be linked to various health concerns could adversely affect our business and we could be subject to litigation relating to these health concerns.

In the past, allegations that serious health risks may result from the use of wireless telecommunications devices or other transmission equipment have adversely affected share prices of some wireless telecommunications companies in the United States. In May 2011, the International Agency for Research on Cancer (the “IARC”), a part of the World Health Organization, announced that it has classified radiofrequency electromagnetic fields associated with wireless phone use as possibly carcinogenic to humans, based on an increased risk for glioma, a malignant type

14

Table of Contents
of brain cancer. The IARC conducts research on the causes of human cancer and the mechanisms of carcinogenesis and aims to develop scientific strategies for cancer control. We cannot assure you that these health concerns will not adversely affect our business. Several class action and personal injury lawsuits have been filed in the United States against several wireless phone manufacturers and carriers, asserting product liability, breach of warranty and other claims relating to radio transmissions to and from wireless phones. Certain of these lawsuits have been dismissed. We could be subject to liability or incur significant costs defending lawsuits brought by our subscribers or other parties who claim to have been harmed by or as a result of our services. In addition, the actual or perceived risk of wireless telecommunications devices could have an adverse effect on our business by reducing the number of our subscribers or the usage per subscriber.

Our ability to deliver services may be disrupted due to a systems failure, shutdown in our networks or natural disaster.

Our services are currently carried through our wireless and fixed-line networks, which could be vulnerable to damage or interruptions in operations due to fires, floods, earthquakes, power losses, telecommunication failures, network software flaws, unauthorized access, computer viruses and similar events, which may occur from time to time. The occurrence of any of these events could impact our ability to deliver services, we may be liable for damages to our customers caused by such interruptions, our reputation may be damaged and our customers may lose confidence in us, which could have a negative effect on our business, financial condition and results of operations.

Depreciation of the value of the Won against the Dollar and other major foreign currencies may have a material adverse effect on our results of operations and the market value of our common shares and ADSs.

Substantially all of our revenues are denominated in Won. Depreciation of the Won may materially affect our results of operations because, among other things, it causes:

an increase in the amount of Won required by us to make interest and principal payments on our foreign currency-denominated debt; and

an increase, in Won terms, of the costs of equipment that we purchase from overseas sources which we pay for in Dollars or other foreign currencies.

Fluctuations in the exchange rate between the Won and the Dollar will affect the Dollar equivalent of the Won price of the our common shares on the KRX KOSPI Market. These fluctuations will also affect:

the amounts a registered holder or beneficial owner of ADSs will receive from the American Depositary Receipt (“ADR”) depositary in respect of dividends, which will be paid in Won to the ADR depositary and converted by the ADR depositary into Dollars;

16


the Dollar value of the proceeds that a holder will receive upon sale in Korea of our common shares; and

the secondary market price of our ADSs.

If SK Inc. causes us to breach the foreign ownership limitations on our common shares by being deemed to be a foreign entity, we may experience a change of control.

The Telecommunications Business Act currently sets a 49.0% limit on the aggregate foreign ownership of our issued shares. Under the Telecommunications Business Act, as amended, a Korean entity, such as SK Inc., is deemed to be a foreign entity if its largest shareholder (determined by aggregating the shareholdings of such shareholder and its related parties) is a foreigner and such shareholder (together with the shareholdings of its related parties) holds 15.0% or more of the issued voting stock of the Korean entity.

While there is currently a pending bill before the National Assembly which proposes to eliminate such limitation on the aggregate foreign ownership, it remains uncertain as to whether the National Assembly will vote in favor of passing such bill or when such vote will take place.

Notwithstanding the above, pursuant to a recentan amendment to the Telecommunications Business Act which became effective onin April 20, 2022, a Korean entity, so long as (i) such entity’s largest shareholder (determined by aggregating the shareholdings of such shareholder and its related parties) is a foreign entity specifically designated by the MSIT incorporated in a country that has entered into a bilateral or multilateral free trade agreement with Korea, and (ii) such shareholder (together with the shareholdings of its related parties) owns 15.0% or more of the

15

Table of Contents
issued voting stock of such entity, may own more than 49.0% of our issued shares but may not exercise its voting rights with respect to the shares held in excess of the 49% ceiling until the end of the MSIT’s Public Interest Review (see “Item 4.B4.B. Business Overview — Foreign Ownership and Investment Restrictions and Requirements”).

As of December 31, 2021,2023, SK Inc. owned 65,668,397

shares of our common stock, or 30.0%, of our issued shares. SK Inc. is currently not deemed to be a foreign entity. However, should SK Inc. be considered to be a foreign shareholder in the future, then its shareholding in us would be included in the calculation of our aggregate foreign shareholding and our aggregate foreign shareholding (based on our foreign ownership level as of December 31, 2021,2023, which we believe was 43.6%41.0%) would exceed the 49.0% ceiling on foreign shareholding. As of December 31, 2021,2023, the two largest foreign shareholders of SK Inc. each held a 3.3% stake therein.

If our aggregate foreign shareholding limit is exceeded, the MSIT may issue a corrective order to us, the breaching shareholder (including SK Inc. if the breach is caused by an increase in foreign ownership of SK Inc.) and the foreign shareholder which owns in the aggregate 15.0% or more of SK Inc. Furthermore, if SK Inc. is considered a foreign shareholder, it will be prohibited from exercising its voting rights with respect to the shares held in excess of the 49.0% ceiling, which may result in a change in control of us. In addition, the MSIT will be prohibited from granting us licenses or permits necessary for entering into new telecommunications businesses until our aggregate foreign shareholding is reduced to below 49.0%. For a description of further actions that the MSIT could take, see “Item 4.B. Business Overview — Law and Regulation — Foreign Ownership and Investment Restrictions and Requirements.”

Risks Relating to Korea

Unfavorable financial and economic developments in Korea may have an adverse effect on us.

We are incorporated in Korea, and a substantial portion of our operations and assets are located in Korea. As a result, we are subject to political, economic, legal and regulatory risks specific to Korea, and our performance and successful fulfillment of our operational strategies are dependent in large part on the overall Korean economy. The economic indicators in Korea in recent years have shown mixed signsDue to the debilitating effects of growth and uncertainty, and starting in 2020, the overallCOVID-19 pandemic on the Korean economy and the economies of Korea’s major trading partners, the economic indicators in Korea have shown mixed signs of deterioration due toand

17


uncertain recovery since the debilitating effectsoutbreak of the

COVID-19
pandemic. See “— The ongoing global pandemicRisks relating to Our Business — Occurrences of a new strain of coronavirus
(“COVID-19”)
andwidespread infectious diseases, including any possible recurrence of other types of widespread infectious diseasesCOVID-19, may materially and adversely affect our business, financial condition and results of operations.” As a result, future growth of the Korean economy is subject to many factors beyond our control, including developments in the global economy.

In recent years, adverse conditions and volatility in the worldwide financial markets, fluctuations in oil and commodity prices, supply chain disruptions and the increasing weakness of the global economy, in particular due towhich have been affected by, among others, the

COVID-19
pandemic, and more recently Russia’s invasion of Ukraine and ensuing sanctions against Russia, difficulties faced by several banks in the United States and Europe, increases in policy interest rates globally (including Korea) to combat rising inflationary pressures, and more recently, escalating hostilities in the Middle East following the Israel-Hamas war, have contributed to the uncertainty of global economic prospects in general and have adversely affected, and may continue to adversely affect, the Korean economy. The value of the Won relative to major foreign currencies has fluctuated significantly and, as a result of uncertain global and Korean economic, social and political conditions, there has been significant volatility in the stock prices of Korean companies recently. Future declines in the Korea Composite Stock Price Index (the “KOSPI”), and large amounts of sales of Korean securities by foreign investors and subsequent repatriation of the proceeds of such sales may adversely affect the value of the Won, the foreign currency reserves held by financial institutions in Korea, and the ability of Korean companies to raise capital. Any future deterioration of the Korean or global economy could adversely affect our business, financial condition and results of operations.

Developments that could have an adverse impact on Korea’s economy include:

declines in consumer confidence and a slowdown in consumer spending, including as a result of severe health epidemics, such as COVID-19, and increases in market interest rates;

rising inflationary pressures leading to increases in the costs of goods and services and a slowdowndecrease in consumer spending, including as a resultpurchasing power;

adverse changes or volatility in foreign currency reserve levels, commodity prices (including oil prices), exchange rates (including fluctuation of the ongoing globalWon against the U.S. dollar, Euro or Japanese Yen exchange rates or revaluation of the Chinese Yuan), interest rates, inflation rates or stock markets;

COVID-19
pandemic;

adverse conditions or developments in the economies of countries and regions that are important export markets for Korea, such as China, the United States, Europe and Japan, or in emerging market economies in Asia or elsewhere, including as a result of deteriorating economic and trade relations between the United

Escalations in tensions with North Korea could have an adverse effect on us and the market value of our common shares and ADSs.

Relations between Korea and North Korea have been tense throughout Korea’s modern history. The level of tension between the two Koreas has fluctuated and may increase abruptly as a result of future events. In particular, there have been heightened security concerns in recent years stemming from North Korea’s nuclear weapon, and ballistic missile and satellite programs as well as its hostile military actions against Korea. Some of the significant incidents in recent years include the following:

North Korea renounced its obligations under the Nuclear Non-Proliferation Treaty in January 2003 and has conducted six rounds of nuclear tests since October 2006, including claimed detonations of hydrogen bombs and warheads that can be mounted on ballistic missiles. Over the years, North Korea has continued to conduct a series of missile tests, including ballistic missiles launched from submarines and intercontinental ballistic missiles that it claims can reach the United States mainland. North Korea has increased the frequency of such activities since the beginning of 2022, firing numerous ballistic missiles, including intercontinental ballistic missiles, and in November 2023, successfully launched its first spy satellite. In response, the Government has repeatedly condemned the provocations and flagrant violations of relevant United Nations Security Council resolutions. In February 2016, the Government also closed the inter-Korea Gaeseong Industrial Complex in response to North Korea’s fourth nuclear

19


test in January 2016. Internationally, the United Nations Security Council has passed a series of resolutions condemning North Korea’s actions and significantly expanding the scope of sanctions applicable to North Korea. Over the years, the United States and the European Union have also expanded their sanctions applicable to North Korea.

Over the years, the United States and the European Union have also expanded their sanctions applicable to North Korea.

In March 2010, a Korean naval vessel was destroyed by an underwater explosion, killing many of the crewmen on board. The Government formally accused North Korea of causing the sinking, while North Korea denied responsibility. Moreover, in November 2010, North Korea fired more than one hundred artillery shells that hit Korea’s Yeonpyeong Island near the Northern Limit Line, which acts as the de facto maritime boundary between Korea and North Korea on the west coast of the Korean peninsula, causing casualties and significant property damage. The Government condemned North Korea for the attack and vowed stern retaliation should there be further provocation.

North Korea’s economy also faces severe challenges, which may further aggravate social and political pressures within North Korea.

Although bilateral summit meetings between Korea and North Korea were held between the two Koreas in April, May and September 2018 and between the United States and North Korea in June 2018, February 2019 and June 2019, there can be no assurance that the level of tensions affecting the Korean peninsula will not escalate in the future. Any further increase in tensions, which may occur, for example, if North Korea experiences a leadership crisis, high-level contacts between Korea and North Korea or between the United States and North Korea break down or military hostilities occur, could have a material adverse effect on our business, financial condition and results of operations and the market value of our common shares and ADSs.

Korea’s legislation allowing class action suits related to securities transactions may expose us to additional litigation risk.

The Securities-related Class Action Act of Korea (the “Securities-related Class Action Act”), enacted in January 2004, allows class action suits to be brought by shareholders of companies (including us) listed on the KRX KOSPI Market for losses incurred in connection with purchases and sales of securities and other securities transactions arising from (1) false or inaccurate statements provided in the registration statements, prospectuses, annual reports, audit reports, and semi-annual or quarterly reports and material fact reports and omissionor omissions of material information in such documents, (2) insider trading, (3) market manipulation and (4) unfair trading. This lawThe Securities-related Class Action Act permits 50 or more shareholders who collectively hold 0.01% of the shares of a company to bring a class action suit against, among others, the issuer and its directors and officers. Because of the relatively recent enactment of the act,Securities-related Class Action Act, there is not enough judicial precedent to predict how the courts will apply the law. Litigation can be time-consuming and expensive to resolve, and can divert management time and attention from the operation of a business. We are not aware of any basis upon which such suit may be brought against us, nor are any such suits pending or threatened. Any such litigation brought against us could have a material adverse effect on our business, financial condition and results of operations.

There are special risks involved with investing in securities of Korean companies, including the possibility of restrictions being imposed by the Government in emergency circumstances.

As we are a Korean company and operate in a business and cultural environment that is different from that of other countries, there are risks associated with investing in our securities that are not typical for investments in securities of companies in other jurisdictions.

Under the Korean Foreign Exchange Transactions Act, if the Government deems that certain emergency circumstances, including a significant disruption in the international balance of payments and international financial markets or extreme difficulty in carrying out currency, exchange rate or other macroeconomic policies due to the movement of capital between Korea and other countries, are likely to occur, it may impose any

20


necessary restriction such as requiring Korean or foreign investors to obtain prior approval from the Ministry of Economy and Finance (the “MOEF”) for the acquisition of Korean securities or for the repatriation of interest, dividends or sales proceeds arising from Korean securities or from disposition of such securities or other transactions involving foreign exchange. See “Item 10.D. Exchange Controls — Korean Foreign Exchange Controls and Securities Regulations.”

Risks Relating to Securities

Sales of our shares by SK Inc. and/or other large shareholders may adversely affect the market value of our common shares and ADSs.

Sales of substantial amounts of our common shares, or the perception that such sales may occur, could adversely affect the prevailing market value of our common shares or ADSs or our ability to raise capital through an offering of our common shares.

As of December 31, 2021,2023, SK Inc. owned 30.0% of our total issued common shares and has not agreed to any restrictions on its ability to dispose of our shares. See “Item 7.A. Major Shareholders.” We can make no prediction as to the timing or amount of any sales of our common shares. We cannot assure you that future sales of our common shares, or the availability of our common shares for future sale, will not adversely affect the prevailing market value of our common shares or ADSs from time to time.

We believe that we may be classified as a passive foreign investment company, or PFIC, for U.S. federal income tax purposes for our taxable year ending December 31, 2021, which could subject U.S. investors in our common shares or ADSs to significant adverse U.S. federal income tax consequences.
Due to fluctuations in our stock price and changes in the value and composition of our assets, including our substantial investment in the stock of SK Hynix prior to the
Spin-off,
we believe that we may be classified as a “passive foreign investment company,” or “PFIC,” for U.S. federal income tax purposes for our taxable year ending December 31, 2021. We do not expect, however, to be classified as a PFIC for the current taxable year or in the reasonably foreseeable future. See “Item 10.E. Additional Information — Taxation — United States Federal Income Tax Considerations — Passive Foreign Investment Company Rules” for additional details.
A
non-U.S.
corporation will be a PFIC if, in any particular taxable year, either (a) 75% or more of its gross income for such year consists of certain types of “passive” income or (b) 50% or more of the value of its assets (generally determined on the basis of a quarterly average) is attributable to assets that produce or are held for the production of passive income.
If we are classified as a PFIC in any taxable year, a U.S. holder (as defined in “Item 10.E. Additional Information — Taxation — United States Federal Income Tax Considerations”) may incur significantly increased U.S. federal income tax on gain recognized on the sale or other disposition of the common shares or ADSs and on the receipt of distributions on the common shares or ADSs to the extent such gain or distribution is treated as an “excess distribution” under the U.S. federal income tax rules, and such U.S. holder may be subject to burdensome reporting requirements. The amount of income tax on any excess distributions will be increased by an interest charge to compensate for tax deferral, calculated as if the excess distributions were earned ratably over the period that the U.S. holder holds its common shares or ADSs. Further, if we are a PFIC for any year during which a U.S. holder holds our commons shares or ADSs, we generally will continue to be treated as a PFIC for all succeeding years during which such U.S. holder holds our common shares or ADSs unless we cease to be a PFIC and the U.S. holder makes a special election.
19

Table of Contents
A U.S. holder may be able to avoid the unfavorable rules described above by electing to mark its ADSs to market, provided the ADSs are treated as “marketable stock.” The ADSs generally will be treated as marketable stock if the ADSs are “regularly traded” on a “qualified exchange or other market” (which includes the New York Stock Exchange (“NYSE”)). Further, it should be noted that only the ADSs and not the common shares are listed on the NYSE. Consequently, a U.S. holder that holds common shares that are not represented by ADSs may not be eligible to make a
mark-to-market
election in respect of those common shares.
U.S. holders are strongly urged to consult their own tax advisors regarding our potential classification as a PFIC and regarding the U.S. federal income tax consequences of acquiring, holding, and disposing of our common shares or ADSs if we are so classified, including the advisability of making a
“mark-to-market”
election, if available. See “Item 10.E. Additional Information — Taxation — United States Federal Income Tax Considerations — Passive Foreign Investment Company Rules” for more details.

If an investor surrenders his or her ADSs to withdraw the underlying shares, he or she may not be allowed to deposit the shares again to obtain ADSs.

Under the deposit agreement, holders of our common shares may deposit those shares with the ADR depositary’s custodian in Korea and obtain ADSs, and holders of ADSs may surrender ADSs to the ADR depositary and receive our common shares. However, under the terms of the deposit agreement, as amended, the depositary bank is required to obtain our prior consent to any such deposit if, after giving effect to such deposit, the total number of our common shares represented by ADSs, which was 14,653,59813,512,383 shares as of March 31, 2022,2024, exceeds a specified maximum, which was 59,712,21673,861,029 shares as of March 31, 2022,2024, subject to adjustment under certain circumstances.

In addition, the depositary bank or the custodian may not accept deposits of our common shares for issuance of ADSs under certain circumstances, including (1) if it has been determined by us that we should block the deposit to prevent a violation of applicable Korean laws and regulations or our articles of incorporation or (2) if a person intending to make a deposit has been identified as a holder of at least 4.0% of our common shares. It is possible that we may not give the consent. Consequently, an investor who has surrendered his or her ADSs and withdrawn the underlying shares may not be allowed to deposit the shares again to obtain ADSs.

An investor in our ADSs may not be able to exercise preemptive rights for additional new shares and may suffer dilution of his or her equity interest in us.

The Korean Commercial Code and our articles of incorporation require us, with some exceptions, to offer shareholders the right to subscribe for new shares in proportion to their existing ownership percentage whenever new shares are issued. If we offer a right to subscribe for additional new common shares or any other rights of similar nature, the ADR depositary, after consultation with us, may make the rights available to an ADS holder or use reasonable efforts to dispose of the rights on behalf of the ADS holder and make the net proceeds available to the ADS holder. The ADR depositary, however, is not required to make available to an ADS holder any rights to purchase any additional shares unless it deems that doing so is lawful and feasible and:

a registration statement filed by us under the Securities Act is in effect with respect to those shares; or

the offering and sale of those shares is exempt from, or is not subject to, the registration requirements of the Securities Act.

21


We are under no obligation to file any registration statement with respect to any ADSs. If a registration statement is required for an ADS holder to exercise preemptive rights but is not filed by us, the ADS holder will not be able to exercise his or her preemptive rights for additional shares. As a result, ADS holders may suffer dilution of their equity interest in us.

Short selling of our ADSs by purchasers of securities convertible or exchangeable into our ADSs could materially adversely affect the market price of our ADSs.

SK Inc., through one or more special purpose vehicles, has engaged and may in the future engage in monetization transactions relating to its ownership interest in us. These transactions have included and may include

20

Table of Contents
offerings of securities that are convertible or exchangeable into our ADSs. Many investors in convertible or exchangeable securities seek to hedge their exposure in the underlying equity securities at the time of acquisition of the convertible or exchangeable securities, often through short selling of the underlying equity securities or similar transactions. Since a monetization transaction could involve debt securities linked to a significant number of our ADSs, we expect that a sufficient quantity of ADSs may not be immediately available for borrowing in the market to facilitate settlement of the likely volume of short selling activity that would accompany the commencement of a monetization transaction. This short selling and similar hedging activity could place significant downward pressure on the market price of our ADSs, thereby having a material adverse effect on the market value of ADSs owned by you.

A holder of our ADSs may not be able to enforce a judgment of a foreign court against us.

We are a corporation with limited liability organized under the laws of Korea. Substantially all of our directors and officers and other persons named in this annual report reside in Korea, and all or a significant portion of the assets of our directors and officers and other persons named in this annual report and substantially all of our assets are located in Korea. As a result, it may not be possible for holders of our ADSs to effect service of process within the United States, or to enforce against us any judgments obtained from the United States courts based on the civil liability provisions of the federal securities laws of the United States. There is doubt as to the enforceability in Korea, either in original actions or in actions for enforcement of judgments of United States courts, of civil liabilities predicated on the United States federal securities laws.

We are generally subject to Korean corporate governance and disclosure standards, which may differ from those in other countries.

Companies in Korea, including us, are subject to corporate governance standards applicable to Korean public companies, which may differ in some respects from standards applicable in other countries, including the United States. As a reporting company registered with the SEC and listed on the NYSE,New York Stock Exchange (“NYSE”), we are subject to certain corporate governance standards as mandated by the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”). However, foreign private issuers, including us, are exempt from certain corporate governance requirements under the Sarbanes-Oxley Act or under the rules of the NYSE. There may also be less publicly available information about Korean companies, such as us, than is regularly made available by public or

non-public
companies in other countries. Such differences in corporate governance standards and less public information available could result in corporate governance practices or disclosures that are perceived as less than satisfactory by investors in certain countries.

INFORMATION ON THE COMPANY

Item 4.A.

History and Development of the Company

As Korea’s first wireless telecommunications service provider, we have a recognized history of leadership and innovation in the domestic telecommunications sector. Today, we remain Korea’s leading wireless telecommunications services provider and have continued to pioneer the commercial development and

22


implementation of

state-of-the-art
wireless technologies. We had 31.933.7 million wireless subscribers, including MVNO subscribers leasing our networks, as of December 31, 2021,2023, representing a market share of 44.3%40.7%, the largest market share among Korean wireless telecommunications service providers. We believe we are also a leader in developing new products and services that reflect the increasing convergence of telecommunications technologies, as well as the growing synergies between the telecommunications sector and other industries.

In February 2012, we acquired an equity stake in SK Hynix, one of the world’s largest memory-chip makers by revenue, for an aggregate purchase price of Won 3.4 trillion, and became its largest shareholder. In November 2021, we transferred all of our 20.1% equity interest in SK Hynix to SK Square pursuant to the

Spin-off,
as further described below.

Effective as of November 1, 2021, we conducted the

Spin-off,
pursuant to which we spun off our equity interests in certain subsidiaries and investees (collectively comprising the
Spin-off
Portfolio Companies) engaged in the semiconductor and certain other
non-telecommunications
businesses, including our security,
e-commerce
and
21

Table of Contents
other new ICT businesses (collectively comprising the
Spin-off
Businesses) to SK Square, a newly established holding company, and we distributed SK Square’s shares of common stock on a pro rata basis to the holders of our common stock.

In connection with the

Spin-off,
we also engaged in a
5-to-1
stock split of our common stock (the “Stock Split”), pursuant to which the par value of our common stock changed from Won 500 per share to Won 100 per share and the number of issued shares of our common stock increased from 72,060,143 shares to 360,300,715 shares, in each case effective as of October 28, 2021. Immediately following, and as a result of, the Stock Split, each ADS outstanding as of October 28, 2021 represented five-ninths of one share of our common stock. On March 31, 2022,2024, we had a market capitalization of approximately Won 13.211.3 trillion (US$10.7 billion, as translated at the noon buying rate of March 31, 2022)8.4 billion) or approximately 0.1%0.5% of the total market capitalization on the KRX KOSPI Market, making us the 26th32nd largest company listed on the KRX KOSPI Market based on market capitalization on that date. Our ADSs, each representing five-ninths of one share of our common stock, have traded on the NYSE since June 27, 1996.

We are a corporation with limited liability organized under the laws of Korea.

We established our telecommunications business in March 1984 under the name Korea Mobile Telecommunications Co., Ltd. We changed our name to SK Telecom Co., Ltd., effective March 21, 1997. In January 2002, we merged with Shinsegi Telecom Co., Ltd. (“Shinsegi”), which was then the third-largest wireless telecommunications service provider in Korea. Our registered office is at SK
T-Tower,
65,
Eulji-ro,
Jung-gu,
Seoul 04539, Korea and our telephone number is
+82-2-6100-2114.
Our website address is http://www.sktelecom.com.

The SEC maintains a website (http://www.sec.gov)(www.sec.gov), which contains reports, proxy and information statements and other information regarding issuers that file electronically with the SEC.

Korean Telecommunications Industry

Established in March 1984, we became the first wireless telecommunications service provider in Korea. We remained the sole provider of wireless telecommunications services until April 1996, when Shinsegi commenced cellular service. The Government began to introduce competition into the fixed-line and wireless telecommunications services markets in the early 1990’s. During this period, the Government allowed new competitors to enter the fixed-line sector, sold a controlling stake in us to the SK Group, and granted a cellular license to our first competitor, Shinsegi. In October 1997, three additional companies began providing wireless telecommunications services under Government licenses to provide wireless telecommunications services. In 2000 and 2001, the Korean wireless telecommunications market experienced significant consolidation. In January 2002, Shinsegi was merged into us. Additionally, two of the other wireless telecommunications services providers merged.

There are currently three mobile network operators in Korea: us, KT and LG U+. As of December 31, 2021,2023, the market share of the Korean wireless telecommunications market, in terms of number of subscribers, of KT

23


and LG U+ was approximately 31.0%29.3% and 24.7%30.0%, respectively (compared to our market share of 44.3%40.7%), each including MVNO subscribers leasing the respective networks. As of December 31, 2021,2023, MVNOs had a combined market share of 14.4%19.2%, of which MVNOs leasing our networks represented 3.0%2.9%, MVNOs leasing KT’s networks represented 7.4%8.6% and MVNOs leasing LG U+’s networks represented 3.9%7.6%.

22

Table In January 2024, the Government allocated 800 MHz of Contents
bandwidth in the 28 GHz spectrum to Stage X to provide nationwide wireless network services. Stage X is required, among other things, to install 6,000 base stations across Korea that use the 28 GHz spectrum by 2027.

Telecommunications industry growth in Korea has been among the most rapid in the world, with fixed-line penetration being under five lines per 100 population in 1978 and increasing to 47.9 lines per 100 population as of December 31, 2006 before decreasing to 23.621.4 lines per 100 population as of December 31, 2021,2023, and wireless penetration increasing from 7.0 subscribers per 100 population in 1996 to 139.3161.3 subscribers per 100 population as of December 31, 2021.2023.

Since the introduction of short text messaging in 1998, Korea’s wireless data market has grown rapidly. This growth has been driven, in part, by the rapid development of wireless Internet service since its introduction in 1999 and the implementation of LTE and 5G technologies providing for fast data transmission speeds and large data transmission capacity. As of December 31, 2021,2023, approximately 60.755.1 million Korean wireless subscribers owned Internet-enabled handsets capable of accessing wireless Internet services, including 53.5 million subscribers that own smartphones that had direct access to the Internet using mobile Internet technology.

The decreases in the penetration rate of smartphones as of December 31, 2023 compared to December 31, 2022, and as of December 31, 2022 compared to December 31, 2021, were primarily due to a faster increase in the number of subscribers of non-mobile phone wireless services, such as tablet computers, wearable devices, IoT devices and others, as compared to the increase in the number of smartphones.

In addition to its well-developed wireless telecommunications sector, Korea has one of the largest Internet markets in the Asia Pacific region. From the end of 2010 to the end of 2021,2023, the number of broadband Internet

24


access subscribers increased from approximately 17.2 million to approximately 22.924.1 million.

As part of our ongoing efforts to pursue such strategies, effective as of November 1, 2021, we conducted the

Spin-off,
pursuant to which we spun off our equity interests in certain subsidiaries and investees (comprising the
Spin-off
Portfolio Companies) engaged in semiconductor and certain other
non-telecommunications
businesses, including our security,
e-commerce
and other new ICT businesses (collectively comprising the
Spin-off
Businesses) to SK Square, a newly established holding company, and we distributed SK Square’s shares of common stock on a pro rata basis to the holders of our common stock. See “Certain Defined Terms and Conventions Used in this Annual Report” for the accounting treatment of the
Spin-off

As part of such vision, we seek to enhance customer engagement levels and strengthen our customer groups,relationships through “A.” (or “A dot”), an innovative mobile application that utilizes generative AI technology and provides users with AI-based personal assistant services, which was first introduced in May 2022 and officially launched in September 2023.

We have also been collaborating with leading Korean AI technology companies as well as other global telecommunications companies in order to accelerate our ongoing transformation to become an AI Company, including by forming the GTAA in July 2023 with Deutsche Telecom of Germany, e& of the United Arab Emirates and Singtel of Singapore, which was later joined by Softbank of Japan in February 2024. The members of the GTAA have agreed to establish a joint venture dedicated to the development of large-language models that

Digital Wireless Network

We offer wireless voice and data transmission services throughout Korea using digital wireless networks, primarily consisting of our 5G network, LTE network, WCDMA network,

Wi-Fi
network and LoRa network. We continually upgrade and increase the capacity of our wireless networks to keep pace with advancements in technology, the growth of our subscriber base and the increased usage of voice and wireless data services by our subscribers. For more information about our capital expenditures relating to our wireless networks, see “Item 5.B. Liquidity and Capital Resources — Capital Requirements — Capital Expenditures.”

5G Network.

5G is the
state-of-the-art
wireless network that enables data to be transmitted at speeds faster than our LTE network with lower latency. We began the operation of our 5G network in December 2018 on a limited basis for business customers, beginning with a few major commercial districts in Seoul and other metropolitan areas. In April 2019, we launched wireless service plans using the 5G network following the commencement of sales of the first
5G-compatible
smartphones, and we are in the process of further expanding our 5G network coverage. Our 5G network coverage whichcurrently includes all of the major metropolitan and other urban areas, as well as subway lines, in Korea, and we have been expanding our 5G network coverage in rural areas by constructing 5G networks that are shared with other mobile network operators in such areas. We expect to be able to provide full nationwide outdoor terrestrial coverage and substantially complete withinfull nationwide coverage in large buildings by the next several years.end of 2024. Our 5G services provided a maximum data transmission speed of 2.75 Gbps, and our 5G penetration, which represents the number of our 5G subscribers as a percentage of our total number of subscribers, in each case including MVNO subscribers leasing our networks, was 41.6%46.8% as of December 31, 2021.2023. We have also deployed our 5G network for mMTC connections relating to our IoT solutions.

We believe that our 5G technology and network infrastructure enable us to provide the fastest 5G data transmission network nationwide. In December 2021,2023, the MSIT announced that our 5G network provided the fastest upload and download speeds among the three mobile network operators, KT, LG U+ and us. The nationwide average download speed of our 5G network was 930988 Mbps compared to 763949 Mbps for KT’s 5G network and 712881 Mbps for LG U+’s 5G network.

LTE Network.

LTE technology has become widely accepted globally as the standard fourth generation technology and enables data to be transmitted at speeds faster than our WCDMA network. Since first commencing our LTE services in July 2011, and
LTE-A
services, which use carrier aggregation technology that combines spectrum frequencies to improve data transmission speeds, in June 2013, we have developed and launched various upgraded LTE networks and related services providing faster network speeds, enhanced connectivity and broader coverage areas. In February 2018, we launched four-band
LTE-A
services utilizing 4x4 multiple-input multiple-output (“MIMO”) technology providing for data transmission speedsOur LTE penetration, which represents the number of up to 1 Gbps, and we commenced five-band
LTE-A
services using 4x4 MIMO technology that provide data transmission speeds of up to 1.15 Gbps in March 2019 and up to 1.25 Gbps in March 2020. With these developments in LTE technology, our LTE penetrationsubscribers as a percentage of our total number of subscribers, in each case including MVNO subscribers leasing our networks, increased to a peak of 79.3% as of December 31, 2019 compared to 49.3% as of December 31, 2013, before decreasing to 63.3%49.9% as of December 31, 20212023 as a result of the ongoing customer migration to the 5G network. We expect that wireless services based on LTE technology will continue to be used by a significant portion of our userssubscriber base in the near future, as wedespite the ongoing expansion of 5G network and our competitors further expand 5G networks and services andgradual migration of wireless service users continue to migrate to the 5G network over time, and plan to continue to deploy improved
LTE-A
LTE technology to increase the maximum data transmission speed of our services.
For
machine-to-machine
connections relating to our IoT solutions, we launched our LTE-M services at speeds of up to 10 Mbps in March 2016, as well as our LTE Cat.M1 services at speeds of up to 0.03 Mbps in April 2018. Upgrades to our LTE technology in recent years have enabled even faster data transmission speeds, as shown below.

network provided the fastest upload and download speeds among the three mobile network operators, KT, LG U+ and us.

The nationwide average download speed of our LTE network was 208.2243 Mbps compared to 138.2171 Mbps for KT’s LTE network and 104.4122 Mbps for LG U+’s LTE network.
WCDMA and CDMA Networks.    
WCDMA technology enables us to offer significantly faster and higher-quality voice and data transmission and supports more sophisticated wireless data transmission services than is possible through our former CDMA network. Since first commencing our WCDMA services in Seoul in 2003, we have expanded our WCDMA network nationwide and implemented various technologies to improve data transmission speeds within our WCDMA network.
CDMA technology is a continuous digital transmission technology that accommodates higher throughput than analog technology by using various coding sequences to allow concurrent transmission of voice and data signals for wireless communication. In January 1996, we launched our first wireless network based on CDMA technology and became the world’s first to commercialize second generation cellular services using the CDMA network. As a result of declining usage and the increasing difficulty of maintaining the network, we terminated our second generation CDMA wireless services in July 2020.

Wi-Fi

technology enables our subscribers with
Wi-Fi-capable
devices such as smartphones, laptops and tablet computers to access mobile Internet. We started to build
Wi-Fi
access points in 2010 and, as of December 31, 2021,2023, we had more than 104,000
120,000 Wi-Fi
access points in public areas such as shopping malls, restaurants, coffee shops, subways and airports where, generally, the demand for high-speed wireless Internet service is high. While each
Wi-Fi
access point typically has a radius of approximately
20-30
meters, some of our
Wi-Fi
hot zones, which have multiple
Wi-Fi
access points, including those installed at public transportation facilities and amusement parks, have much wider service areas.

LoRa Networks

. A
Low-Power
Wide-Area network based on LoRa technology is a type of telecommunications network designed to support communication among IoT devices. It can transmit data over tens of kilometers while consuming much less power than LTE networks, lowering costs for connectivity as well as lowering battery power usage. We completed the nationwide deployment of our LoRa network in July 2016. We expect that our LoRa network will provide the infrastructure necessary for the growth of not only our own IoT solutions business but also the IoT industry as a whole.

Network Infrastructure

The principal components of our wireless networks are:

base stations (or cell sites)
,
which are physical locations equipped with transmitters, receivers and other equipment that communicate by radio signals with wireless handsets within range of the cell (typically a 3 to 40 kilometer radius);
switching stations
,
which switch voice and data transmissions to their proper destinations, which may be, for instance, a mobile phone of one of our subscribers (for which transmissions would originate and terminate on our wireless networks), a mobile phone of a KT or LG U+ subscriber (for which transmissions would be routed to KT’s or LG U+’s wireless networks, as applicable), a fixed-line telephone number (for which calls would be routed to the public switched telephone network of a fixed-line network operator), an international number (for which calls would be routed to the network of a long distance service provider) or an Internet site; and
transmission lines
,
which link base stations to switching stations and switching stations with other switching stations.

As of December 31, 2021,2023, our 5G, LTE and WCDMA networks had an aggregate of 58,385

59,392base stations. As we continue to expand our 5G network coverage, the number of our base stations is expected to increase accordingly.
We

To date, we have purchased substantially all of the equipment for our networks from Samsung Electronics, Ericsson–LGEricsson-LG and Nokia. Most of the transmission lines we use, including virtually all of the lines linking switching stations, as well as a portion of the lines linking base stations to switching stations, comprise optical fiber lines that we own

and operate directly. However, we have not undertaken to install optical fiber lines to link every base station and switching station. In places where we have not installed our own transmission lines, we have leased lines from KT and LG U+.
We intend to increase the efficiency of our network utilization and provide optimal services by internalizing transmission lines.

We use a wireless network surveillance system. This system oversees the operation of base stations and allows us to monitor our main equipment located throughout the country from one monitoring station. The automatic inspection and testing provided to the base stations lets the system immediately rebalance to the most suitable setting, and the surveillance system provides for automatic dispatch of repair teams and quick recovery in emergency situations.

Marketing, Distribution and Customer Service

Marketing.

Our marketing strategy is focused on offering solutions tailored to the needs of our various customer segments, promoting our brand and leveraging our extensive distribution network. Our marketing plan includes a coordinated program of television, print, radio, outdoor signage, Internet and
point-of-sale
media promotions designed to relay a consistent message across all of our markets. We market our wireless products and services under the “T” brand, which signifies the centrality of “Telecommunications” and “Technology” to our business and also seeks to emphasize our commitment to providing “Top” quality, “Trustworthy” products and services to our customers.

We have implemented certain information technology improvements in connection with our marketing strategy, including customer management systems, as well as more effective information security controls. We believe these upgrades have enhanced our ability to process and utilize marketing- and subscriber-related data, which, in turn, has helped us to develop more effective and targeted marketing strategies. We currently operate a customer information system designed to provide us with an extensive customer database. Our customer information system includes a billing system that provides us with comprehensive account information for internal purposes and enables us to efficiently respond to customer requests. Our customers can also change their rate plans, verify the charges accrued on their accounts, receive their bills online and send text messages to our other subscribers through our website at www.tworld.co.kr and through our “T world” mobile application.

We strive to improve subscriber retention through our T Membership program, which is a membership service available to our wireless subscribers. Our T Membership program provides various membership benefits to its members such as discounts with our membership partners for dining, shopping, entertainment and travel, membership points accumulation, access to our online membership shopping mall and invitations to various promotional events. Although our competitors also have similar membership programs, we believe that our T Membership program has a competitive advantage over our competitors’ membership programs due to our large subscriber base and breadth of membership benefits.

Distribution.

We use a combination of an extensive network, including branch offices and stores, directly operated by us through our subsidiary, PS&Marketing, more than 3,1402,900 authorized exclusive dealers and an extensive network of independent retailers in order to increase subscriber growth while reducing subscriber acquisition costs.

As part of our initiative to provide a differentiated customer service experience, we operate T Premium Stores that allow our potential and existing subscribers to receive detailed information on our subscription services and “T Factory” stores to further experience certain of our services such as our services that are available through our IoT solutions and platform services. In October 2020, we opened the first T Factory, a facility that offers a wide range of experiences with wireless devices as well as our subscription services and also includes an unmanned store that is open seven days a week and 24 hours a day.

As of December 31, 2021,2023, we operated 7901,065 T Premium Stores and 50 T Factory stores.
Stores.

In addition, we operate an online distribution channel, “T Direct Shop,” through which subscribers can conveniently purchase wireless devices and subscribe to our services online. We also operate a dedicated online shop on 11st, our former subsidiary Eleven Street’s

e-commerce
marketplace. In light of increasing customer preference for online service, amidin part due to the ongoing
COVID-19
pandemic, the level of distribution of our wireless
32

Table of Contents
devices and our services through online channels has significantly increased in recent years. We intend to continue to develop our online distribution channel to leverage our offline distribution capabilities to provide convenience and additional value to our subscribers. For example, subscribers purchasing wireless devices through T Direct Shop can opt to pick up their devices at one of our offline stores.

Currently, authorized dealers are entitled to an initial commission for each new subscriber registered by the dealer, as well as an average ongoing commission calculated as a percentage of that subscriber’s monthly plan-based rate for the first five years. In order to strengthen our relationships with our exclusive dealers, we offer a dealer financing plan, pursuant to which we provide to each authorized dealer a loan of up to Won 4.0 billion (Won 5.0 billion if collateral is pledged) which can be used for operational expenditures with a repayment period of up to three years.11 months. We also provide loans to our authorized dealers for financing deposits and key money in connection with securing retail space with a repayment period of up to 30 months. As of December 31, 2021,2023, we had an aggregate of Won 63.669.6 billion outstanding in loans to authorized dealers.

We believe that such acquisition will strengthen our online distribution capabilities and create opportunities for synergies with our other businesses in the ICT sector.

Interconnection

Our wireless and fixed-line networks interconnect with the public switched telephone networks operated by KT and SK Broadband and, through their networks, with the international gateways of KT and LG U+, as well as the networks of the other wireless telecommunications service providers in Korea. These connections enable our subscribers to make and receive calls from telephones outside our networks. Under Korean law, certain service providers, including us, are required to permit other service providers to interconnect to their networks. If a new service provider desires interconnection with the networks of an existing service provider but the parties are unable to reach an agreement within 90 days, the new service provider can appeal to the KCC.

Domestic Calls

Guidelines issued by the MSIT require that all interconnection charges levied by a regulated carrier take into account (i) the actual costs to that carrier of carrying a call or (ii) imputed costs. The MSIT determines

36

Table of Contents
interconnection rates applicable to each carrier based on changes in traffic volume, taking into account other factors such as research results, competition and trends in technology development.

Wireless-to-Fixed-line.

According to our interconnection arrangement with KT, for a call from our wireless network to KT’s fixed-line network, we collect the usage rate from our wireless subscriber and in turn pay KT the interconnection charges. Similarly, KT pays interconnection charges to SK Broadband for a call from KT’s wireless network to SK Broadband’s fixed-line network. The interconnection rate applicable to both KT and SK Broadband was Won 7.967.22 per minute, Won 8.567.59 per minute and Won 9.157.96 per minute for 2023, 2022 and 2021, 2020 and 2019, respectively.

Fixed-line-to-Wireless.

The MSIT determines interconnection arrangements for calls from a fixed-line network to a wireless network. For a call initiated by a fixed-line user to one of our wireless subscribers, the fixed-line network operator collects our usage fee from the fixed-line user and remits to us an interconnection charge. Interconnection with KT accounts for substantially all of our
fixed-line-to-wireless
interconnection revenue and expenses. The interconnection rate paid by fixed-line network service providers to each wireless network service provider was Won 10.339.17 per minute, Won 10.619.65 per minute and Won 11.6410.33 per minute for 2023, 2022 and 2021, 2020 and 2019, respectively.

Wireless-to-Wireless.

Interconnection charges also apply to calls between wireless telephone networks in Korea. Under these arrangements, the operator originating the call pays an interconnection charge to the operator terminating the call. The applicable interconnection rate is the same as the
fixed-line-to-wireless
interconnection rate set out in the table above.

Our revenues from the

wireless-to-wireless
interconnection charges were Won 401.3 billion in 2023, Won 438.9 billion in 2022 and Won 458.6 billion in 2021, Won 449.1 billion in 2020 and Won 463.8 billion in 2019.2021. Our expenses from these charges were Won 392.4 billion in 2023, Won 434.8 billion in 2022 and Won 459.6 billion in 2021, Won 451.6 billion in 2020 and Won 464.1 billion in 2019.2021.

39


International Calls and International Roaming Arrangements

With respect to international calls, if a call is initiated by our wireless subscribers, we bill the wireless subscriber for the international charges of KT, LG U+ or SK Broadband, and we receive interconnection charges from such operators. If an international call is received by our subscriber, KT, LG U+ or SK Broadband pays interconnection charges to us based on our imputed costs.

To complement the services we provide to our subscribers in Korea, we offer international voice and data roaming services. We charge our subscribers usage fees for global roaming service and, in turn, pay foreign wireless network operators fees for the corresponding usage of their network. For a more detailed discussion of our global roaming services, see “— Wireless Services” above.

Competition

We operate in highly saturated and competitive markets, and we believe that our subscriber growth is affected by many factors, including the expansion and technical enhancement of our networks, the development and deployment of new technologies, the effectiveness of our marketing and distribution strategy, the quality of our customer service, the introduction of new products and services, competitive pricing of our rate plans, new market entrants and regulatory changes.

Historically, there has been considerable consolidation in the telecommunications industry, resulting in the current competitive landscape comprising three mobile and fixed network operators in the Korean market, KT, LG U+ and us. Each of our competitors has substantial financial, technical, marketing and other resources to respond to our business offerings.

Cellular Services

As of December 31, 2021,2023, we had 31.933.7 million subscribers, representing a market share of approximately 44.3%40.7%, including MVNO subscribers leasing our networks. As of December 31, 2021,2023, KT and LG U+ had 22.324.3 million and 17.724.8 million subscribers, respectively, representing approximately 31.0%29.3% and 24.7%30.0%, respectively, of the total number of wireless subscribers in Korea on such date, each including MVNO subscribers leasing its networks. As of December 31, 2021,

In 2023, we had 9.9 million 5G subscribers and KT and LG U+ had 5.0 million and 4.6 million 5G subscribers, respectively, each including MVNO subscribers leasing its networks. As of December 31, 2021, we had 20.2 million LTE subscribers and KT and LG U+ had 14.7 million and 13.3 million LTE subscribers, respectively, each including MVNO subscribers leasing its networks.

In 2021, we had 4.91.7 million activations and 4.42.0 million deactivations. For 2021,2023, our monthly churn rate ranged from 0.7% to 0.9%, with an average monthly churn rate of 0.8%, which decreased from 1.2% in 2020.remained unchanged compared to

23.1%, in each case excluding MVNO subscribers.

Our competitors for subscriber activations include MVNOs, including MVNOs that lease our networks. MVNOs generally provide rate plans that are relatively cheaper than similar rate plans of the wireless network providers from which they lease their networks, including us. Currently, 1314 MVNOs provide wireless telecommunications services using the networks leased from us. As of December 31, 2021,2023, MVNOs had a combined market share of 14.4%19.2%, of which MVNOs leasing our networks represented 3.0%2.9%, MVNOs leasing KT’s networks represented 7.4%8.6% and MVNOs leasing LG U+’s networks represented 3.9%7.6%.

In recent years, a number of new entrants have entered the MVNO business, including affiliates of leading financial institutions in Korea. Some of these new entrants have engaged in aggressive marketing campaigns and promotional discounts while leveraging the brand power of their affiliates as part of their efforts to gain subscribers. Partly as a result of such efforts, the combined market share of MVNOs has increased in recent years from 14.4% as of December 31, 2021 to 16.9% as of December 31, 2022 and 19.2% as of December 31, 2023, in terms of number of subscribers.

Historically, competition in the wireless telecommunications business had caused us to significantly increase our marketing and advertising expenses from time to time depending on the prevailing competitive landscape, with

our marketing expenses as a percentage of SK Telecom’s revenue, on a separate basis, reaching a peak of 28.2% in 2012. Such percentage was 25.6% in 2019, 26.1% in 2020 and 26.6% in 2021. While our marketing expenses as a percentage of SK Telecom’s revenue, on a separate basis, have slightly increased2021, 24.7% in each of the last two years primarily due to increased marketing activities following the introduction of our 5G wireless services, we2022 and 24.2% in 2023. We believe that the maturity of the overall wireless telecommunication market and the implementation of the MDDIA, which prohibits wireless telecommunications service providers from unfairly providing discriminatory subsidies based on certain criteria, have contributed to the general stabilization of our marketing expenses in recent years. For a more detailed discussion of the MDDIA, including the Government’s recent indication to seek its abolishment in order to encourage wireless service providers to offer more differentiated customer benefits to consumers, see “— Law and Regulation — Rate Regulation” below.

We face competition from KT and LG U+ as well as other platform service providers in our other cellular service businesses. For example, our Smart Home service competes with KT’s Giga IoT Home service and LG U+’s IoT@Home service.

Fixed-Line Telecommunications Services

Our fixed-line telephone service competes with KT and LG U+ as well as providers of other VoIP services. As of December 31, 2021,2023, our market share of the fixed-line telephone and VoIP service market was 15.7% (including the services provided by SK Broadband) in terms of number of subscribers compared to KT with 56.3%54.2% and LG U+ with 19.0%18.7%.

We are the second largestsecond-largest provider of broadband Internet access services in Korea in terms of both revenue and subscribers, and our network covered more than 86%a substantial majority of households in Korea as of December 31, 2020.

2023. As of December 31, 2021,2023, our market share of the broadband Internet market was 28.7% in terms of number of subscribers compared to KT with 41.2%40.8% and LG U+ with 20.7%21.4%.

Our IPTV and cable TV services compete with other providers of pay TV services, including KT, LG U+ and cable companies. As of December 31, 2021,2023, our market share of the pay TV market (which includes IPTV, cable TV and satellite TV) in terms of number of subscribers was 25.0%26.1% compared to KT with 36.2%36.5% (including its IPTV, cable TV and satellite TV services) and LG U+ with 25.3%24.7% (including its IPTV and cable TV services), and the collective market share of other pay TV providers was 13.4%12.8%. Furthermore, our IPTV and cable TV services are facing an increasing level of competition from global operators of online video streaming platforms, such as YouTube, Netflix, Disney Plus and Amazon Video,Apple TV, leading domestic video streaming platforms such as TVING, WatchaaWavve (which is seeking to merge with TVING pursuant to a memorandum of understanding entered into in December 2023), Coupang Play and Wavve,Watcha, and the video services offered by leading domestic online and mobile search and communications platforms including NAVER and Kakao, as such services continue to become increasingly popular to serve as a substitute to traditional television programming.

Recently,

Over the past few years, the Korean fixed-line telecommunications industry has been goinggone through significant consolidation involving major pay television service providers. We completed the Tbroad Merger in April 2020, as a result offollowing which we have become the third-largest pay TV provider in Korea in terms of number of subscribers as of December 31, 2020. In December 2019, LG U+ acquired a majority equity stake in LG HelloVision to becomebecame the second-largest pay TV provider in Korea in terms of number of subscribers as of December 31, 2021. 2023. In December 2019, LG U+ acquired a majority equity stake in LG HelloVision.In August 2021, KT acquired HCN, a major Korean cable TV service provider, through its subsidiary KT Skylife. Such transactions, as well as further consolidation in the fixed-line telecommunications industry, may result in increased competition, as the entities emerging from such consolidation and other remaining players in the industry may actively pursue expanding or protecting their respective market shares.

Furthermore, the Government has historically enforced regulations on cable TV and IPTV service providers that prohibited them from having a market share of more than

one-third
of the total number of subscribers in the relevant pay TV market on each of their respective platforms. In June 2015, the Government amended the regulation to impose the same limit on the market share of the entire pay TV market, including satellite TV service providers as well. Such amended regulation, however, expired in June 2018. There are bills currently pending in the National Assembly to abolish the previous market share regulations on cable TV and IPTV service providers. It is uncertain whether such bills will be passed.

Other Investments and Relationships

We have investments in severala number of other businesses and companies and have entered into various business arrangements with other companies. For example, we formed a strategic alliance in October 2019 with Kakao, a Korean Internet company and the operator of Korea’s most popular mobile messaging application, to collaborate in the ICT sector through the sale of 1,266,620 of our treasury shares to Kakao, representing a 1.6% interest, for Won 300.0 billion and a concurrent issuance by Kakao of 2,177,401 of its shares, representing a 2.5% interest, to us for Won 302.3 billion.In addition, in July 2022, we entered into a strategic alliance with Hana Financial Group, a leading financial holding company in Korea with subsidiaries having significant presences in commercial banking, credit card business, securities brokerage and insurance, among others, to seek synergies through convergence between finance and ICT technology. As part of December 31, 2021, our principal investments includedsuch strategic alliance, we transferred the entirety of our 15.0% equity interest in KEB HanaCard Co., Ltd.

Law and Regulation

Overview

Korea’s telecommunications industry is subject to comprehensive regulation by the MSIT, which is responsible for information and telecommunications policies. The MSIT regulates and supervises a broad range of communications issues, including:

entry into the telecommunications industry;

42


scope of services provided by telecommunications service providers;

allocation of radio spectrum;

setting of technical standards and promotion of technical standardization;

rates, terms and practices of telecommunications service providers;

interconnection and revenue-sharing between telecommunications service providers;

research and development of policy formulation for information and telecommunications; and

competition among telecommunications service providers.

The MSIT is charged with regulating information and telecommunications and the KCC is charged with regulating the public interest aspects of and fairness in broadcasting.

Telecommunications service providers are currently classified into two categories: network service providers and value-added service providers. We are classified as a network service provider because we provide telecommunications services with our own telecommunications networks and related facilities. As a network service provider, we were previously required to obtain a license from the MSIT for the services we provide. However, an amendment to the Telecommunications Business Act, pursuant to which companies meeting certain regulatory criteria may become a network service provider without a separate license requirement, went into effect in June 2019. Our licenses permit us to provide cellular services, third generation wireless telecommunications services using WCDMA and WiBro technologies, fourth generation wireless telecommunications services using LTE technology and fifth generation wireless telecommunications services using 5G technology.

The MSIT may revoke our licenses or suspend any of our businesses if we fail to comply with its rules, regulations and corrective orders, including the rules restricting beneficial ownership and control and corrective orders issued in connection with any violation of rules restricting beneficial ownership and control or any violation of the conditions of our licenses. Alternatively, in lieu of suspension of our business, the MSIT or, depending on the subject matter of the violation, the KCC may levy a monetary penalty of up to 3.0% of the average of our annual revenue for the preceding three fiscal years. A network service provider that wants to cease its business or dissolve must notify its users 60 days prior to the scheduled date of cessation or dissolution and obtain MSIT approval.

In the past, the Government has stated that its policy was to promote competition in the Korean telecommunications market through measures designed to prevent the dominant service provider in any such market from exercising its market power in such a way as to prevent the emergence and development of viable competitors. While all network service providers are subject to MSIT regulation, we are subject to increased regulation because of our position as the dominant wireless telecommunications services provider in Korea.

Competition Regulation

The KCC is charged with ensuring that network service providers engage in fair competition and has broad powers to carry out this goal. If a network service provider is found to be in violation of the fair competition requirement, the KCC may take corrective measures it deems necessary, including, but not limited to, prohibiting further violations, requiring amendments to the articles of incorporation or to service contracts with customers, requiring the execution or performance of, or amendments to, interconnection agreements with other network service providers and prohibiting advertisements to solicit new subscribers. The KCC is required to notify the Minister of the MSIT upon ordering certain corrective measures.

In addition, we qualify as a “market-dominating business entity” under the Fair Trade Act. Accordingly, we are prohibited from engaging in any act of abusing our position as a market-dominating entity, such as

43


unreasonably determining, maintaining or altering service rates, unreasonably controlling the rendering of services, unreasonably interfering with business activities of other business entities, hindering unfairly the entry of newcomers or substantially restricting competition to the detriment of the interests of consumers.

Because we are a member company of the SK Group, which is a large business group as designated by the FTC,KFTC, we are subject to the following restrictions under the Fair Trade Act:

Restriction on debt guarantee among affiliates.
    Any affiliate within the SK Group may not guarantee the debts of another domestic affiliate, except for certain guarantees prescribed in the Fair Trade Act, such as those relating to the debts of a company acquired for purposes of industrial rationalization, bid deposits for overseas construction work or technology development funds.
Restriction on cross-investment.
    A member company of the SK Group may not acquire or hold shares in an affiliate belonging to the SK Group that owns shares in the member company.
Restrictions on circular investments.    
A member company of the SK Group may not acquire or hold shares which would constitute “circular investments” in an affiliate company which also forms part of the SK Group where “circular investments” refer to a cross-affiliate shareholding relationship under which three or more affiliate companies become connected through cross affiliate shareholdings by owning shares in other affiliates or by becoming an entity whose shares are owned by other affiliates.
Public notice of board resolution on large-scale transactions with specially related persons.
    If a member company of the SK Group engages in a transaction with a specially related person in the amount of 5.0% or more of the member company’s capital or
paid-in
capital or for Won 5.0 billion or more, the transaction must be approved by a resolution of the member company’s board of directors and the member company must publicly disclose the transaction.
Restrictions on investments by subsidiaries and
sub-subsidiaries
of holding companies.
    The Fair Trade Act prohibits subsidiaries of holding companies from investing in, or holding shares of common stock of, domestic affiliates that belong to the same large business group, unless such domestic affiliates are their own subsidiaries. Furthermore, any subsidiaries of a holding company’s subsidiaries
(“sub-subsidiaries”)
are prohibited from investing in, or holding shares of common stock of, domestic affiliates that belong to the same large business group, unless all shares issued by the affiliates are held by the
sub-subsidiary.
Therefore, we and other subsidiaries of SK Inc. may not invest in any domestic affiliate that is also a member company of the SK Group, except in the case where we invest in our own subsidiary or where another subsidiary of SK Inc. invests in its own subsidiary.
Public notice of the current status of a business group.
    Under the Fair Trade Act and the Enforcement Decree thereof, a member company of the SK Group must publicly disclose the general status of the SK Group, including the name, business scope and financial status of affiliates, information on the officers of affiliates, information on shareholding and cross-investments between member companies of the SK Group, information on transactions with certain related persons and, if a member company engages in a transaction with an affiliated company in the amount of 5.0% or more of the member company’s quarterly sales or Won 5.0 billion or more, information on transactions with such affiliated company on a quarterly basis.

Restriction on debt guarantee among affiliates. Any affiliate within the SK Group may not guarantee the debts of another domestic affiliate, except for certain guarantees prescribed in the Fair Trade Act, such as those relating to the debts of a company acquired for purposes of industrial rationalization, bid deposits for overseas construction work or technology development funds.

Restriction on cross-investment. A member company of the SK Group may not acquire or hold shares in an affiliate belonging to the SK Group that owns shares in the member company.

Restrictions on circular investments. A member company of the SK Group may not acquire or hold shares which would constitute “circular investments” in an affiliate company which also forms part of the SK Group where “circular investments” refer to a cross-affiliate shareholding relationship under which three or more affiliate companies become connected through cross affiliate shareholdings by owning shares in other affiliates or by becoming an entity whose shares are owned by other affiliates.

Public notice of board resolution on large-scale transactions with specially related persons. If a member company of the SK Group engages in a transaction with a specially related person in an amount exceeding the lesser of (1) Won 10 billion and (2) 5.0% of the larger of the total capital or capital stock of the member company (provided, however, in cases where the total capital or capital stock of the member company is less than Won 500 million, the threshold set forth in (1) above is set at Won 500 million), the transaction must be approved by a resolution of the member company’s board of directors and the member company must publicly disclose the transaction.

Restrictions on investments by subsidiaries and sub-subsidiaries of holding companies. The Fair Trade Act prohibits subsidiaries of holding companies from investing in, or holding shares of common stock of, domestic affiliates that belong to the same large business group, unless such domestic affiliates are their own subsidiaries. Furthermore, any subsidiaries of a holding company’s subsidiaries (“sub-subsidiaries”) are prohibited from investing in, or holding shares of common stock of, domestic affiliates that belong to the same large business group, unless all shares issued by the affiliates are held by the sub-subsidiary. Therefore, we and other subsidiaries of SK Inc. may not invest in any domestic affiliate that is also a member company of the SK Group, except in the case where we invest in our own subsidiary or where another subsidiary of SK Inc. invests in its own subsidiary.

Public notice of the current status of a business group. Under the Fair Trade Act and the Enforcement Decree thereof, a member company of the SK Group must publicly disclose the general status of the SK Group, including the name, business scope and financial status of affiliates, information on the officers of affiliates, information on shareholding and cross-investments between member companies of the SK Group, information on transactions with certain related persons and, if a member company engages in a transaction with an affiliated company in the amount of 5.0% or more of the member company’s quarterly sales or Won 5.0 billion or more, information on transactions with such affiliated company on a quarterly basis.

Rate Regulation

Network service providers whose sales proceeds exceed the amount prescribed by law must report to the MSIT the rates and contractual terms for each type of service they provide. Prior to December 2020, as the dominant network service provider for specific services (based on having the largest market share in terms of number of subscribers and meeting certain revenue thresholds), we had to obtain prior approval of the MSIT on our rates and terms of service; provided, however, that such

pre-approval
of the MSIT was not required to reduce the rates for any type of services provided under the MSIT-approved contractual terms. The MSIT’s policy was to approve rates if they were appropriate, fair and reasonable (that is, if the rates had been reasonably calculated, considering supply costs, profits, classification of costs and profits for each service, cost savings through changes in the way services were provided and the influence on fair competition, among others). The MSIT could order changes in the submitted rates if it deemed the rates to be significantly unreasonable or against public policy. In December 2020, however, the Telecommunications Business Act was amended to change such approval requirement to a reporting requirement. Under the newcurrent reporting requirement, which does not apply to other network service providers with respect to the rates they provide, the MSIT has fifteen days to object to any new rates and terms of service reported by us, and we may implement such new rates and terms of service after the
fifteen-day
period expires in the absence of the MSIT’s objection.

44


Furthermore, in 2007, the Government announced a “road map” highlighting revisions in regulations to promote deregulation of the telecommunications industry. In accordance with the road map and pursuant to the Combined Sales Regulation, promulgated in May 2007, telecommunications service providers in Korea are now permitted to bundle their services, such as wireless data transmission service, wireless voice transmission service, broadband Internet access service, fixed-line telephone service and IPTV service, at a discounted rate; provided, however, that we and KT, as market-dominating business entities under the Telecommunications Business Act, allow other competitors to employ the services provided by us and KT, respectively, so that such competitors can provide similar discounted package services. In September 2007, the regulations and provisions under the Telecommunications Business Act were amended to permit licensed transmission service providers to offer local, domestic long-distance and international telephone services, as well as broadband Internet access and Internet phone services, without additional business licenses.

Moreover, an MVNO system under which the MSIT may designate and obligate certain wireless telecommunications services providers to allow an MVNO, at such MVNO’s request, to use their telecommunications network facilities at a rate mutually agreed upon that complies with the standards set by the MSIT became effective on March 14, 2017 under the amended Telecommunications Business Act. We were designated as the only wireless telecommunications services provider obligated to allow the other wireless telecommunications services provider to use our telecommunications network facilities. The expiration of such system has beenwas extended to September 22, 2022 pursuant to an amendment to the Telecommunications Business Act. While such regulatory requirement expired in September 2022, we have continued to comply with such requirement pending future regulatory development, and in December 2023, a bill indefinitely extending such requirement was passed by the National Assembly. Currently, 1314 MVNOs provide wireless telecommunications services using the networks leased from us.

On October 1, 2014, the MDDIA, enacted for the purpose of establishing a transparent and fair mobile distribution practice, became effective. The MDDIA limits the amount of subsidies a wireless telecommunications service provider can provide to subscribers in order to prevent excessive competition among wireless telecommunications service providers. Pursuant to the MDDIA, wireless telecommunications service providers are prohibited from (i) unfairly providing discriminatory subsidies based on criteria such as type of subscription, subscription plan and characteristics of the subscriber and (ii) entering into a separate agreement with subscribers imposing obligations to use a specific subscription plan as a condition for providing subsidies. While the Government indicated in January 2024 that it will seek to abolish the MDDIA in order to encourage wireless service providers to offer more differentiated customer benefits to consumers, the timing of such abolishment, if at all, remains uncertain. In connection with such policy objectives, the Government amended the Enforcement Decree of the MDDIA in March 2024, pursuant to which wireless telecommunications service providers may provide more liberal subsidies to subscribers that are switching their wireless telecommunications providers based on certain criteria specified by the KCC, including the expected profits to the wireless telecommunications service providers and subscribers’ costs of switching wireless telecommunications service providers. See “Item 5.A. Operating Results — Overview — Rate Regulations.”

In addition, under the MDDIA, wireless telecommunications service providers are obliged to provide certain benefits, such as discounted rates, to subscribers who subscribe to their service without receiving subsidies. In June 2017, the State Affairs Planning Advisory Committee of Korea announced that it would encourage wireless telecommunications service providers, including us, to increase the applicable discount rate offered to subscribers from 20% to 25%, which we adopted in September 2017, and to offer additional discounts to low income customers, including those on government welfare programs and senior citizen recipients of the basic pension, which we implemented in December 2017 and July 2018, respectively. Although the Government has recently indicated that it will seek to abolish the MDDIA as described above, it has also suggested that such discounted rates may be retained through a related amendment to the Telecommunications Business Act. We cannot provide assurance that we will not provide other rate discounts or lower-priced subscription plans in the future to comply with the Government’s public policy guidelines or suggestions.

Interconnection

Dominant network service providers such as ourselves that own essential infrastructure facilities or possess a certain market share are required to provide interconnection of their telecommunications network facilities to other service providers upon request. The MSIT sets and announces the standards for determining the scope, procedures, compensation and other terms and conditions of such provision, interconnection or

co-use.
We have entered into interconnection agreements with KT, LG U+ and other network service providers permitting these entities to interconnect with our network. We expect that we will be required to enter into additional agreements with new operators as the MSIT grants permits to additional telecommunications service providers.

Frequency Allocation

The MSIT has the discretion to allocate and adjust the frequency bandwidths for each type of service and may auction off the rights to certain frequency bandwidths. Upon allocation of new frequency bandwidths or adjustment of frequency bandwidths, the MSIT is required to give a public notice. The MSIT also regulates the frequency to be used by each radio station, including the transmission frequency used by equipment in our base stations. All of our frequency allocations are for a definite term. We pay fees to the MSIT for our frequency usage that are determined based upon our number of subscribers, frequency usage by our networks and other factors. For 2021, 20202023, 2022 and 2019,2021, the fee amounted to Won 120.8102.5 billion, Won 136.6103.9 billion and Won 133.1120.8 billion, respectively.

We currently use 10 MHz of bandwidth in the 2.1 GHz spectrum for our WCDMA services, 30 MHz of bandwidth in the 2.1 GHz spectrum, 20 MHz of bandwidth in the 800 MHz spectrum, 35 MHz of bandwidth in the 1.8 GHz spectrum and 60 MHz of bandwidth in the 2.6 GHz spectrum for our LTE services, as well as 100 MHz of bandwidth in the 3.5 GHz spectrum for our 5G services. In December 2022, citing the lack of progress made to date with respect to the implementation of 5G infrastructure for our use of the 28 GHz spectrum (800 MHz of bandwidth which was allocated to us in December 2018 for a period of five years until November 2023), the MSIT reduced the duration of our license for the use of such bandwidth by six months and asked us to install 15,000 base stations that use the 28 GHz spectrum by the end of May 2023, which we were not able to do within the Government’s requested timetable. Furthermore, in December 2022, the Government cancelled the allocations of bandwidth in the 28 GHz spectrum that had been provided to KT and LG U+, also citing the lack of progress made by these companies. In January 2024, the Government allocated 800 MHz of bandwidth in the 28 GHz spectrum for our 5Gto Stage X to provide nationwide wireless network services. In 2020, we recognized an impairment loss of Won 186.0 billion in connection with the frequency usage rights for the 800 MHz of bandwidth inStage X is required, among other things, to install 6,000 base stations across Korea that use the 28 GHz spectrum as the carrying amount exceeded the recoverable amount.by 2027.

Mandatory Contributions and Obligations

All telecommunications service providers other than (i) value-added service providers and regional paging service providers or (ii) any telecommunications service providers whose net annual revenue is less than an amount determined by the MSIT (currently set at Won 30.0 billion) are required to provide “universal”

46


telecommunications services including local telephone services, local public telephone services, telecommunications services for remote islands and wireless communication services for ships and telephone services for handicapped and

low-income
citizens, or contribute toward the supply of such universal services. The MSIT designates universal services and the service provider who is required to provide each service. Currently, under the MSIT guidelines, we are required to offer a discount of between 30.0% to 50.0% of our monthly fee for wireless telecommunications services to handicapped and
low-income
citizens.

In addition to such universal services for handicapped and

low-income
citizens, we are also required to make certain annual monetary contributions to compensate for other service providers’ costs for the universal services. The size of a service provider’s contribution is based on its net annual revenue for the previous year (calculated pursuant to the MSIT guidelines, which differ from our accounting practices).We paid. We recognized expenses relating to such contributions amounting toof Won 18.931.1 billion, Won 17.422.1 billion and Won 16.118.7 billion in 2021, 20202023, 2022 and 2019,2021, respectively. As a
43

Table of Contents
wireless telecommunications services provider, we are not considered a provider of universal telecommunications services and do not receive funds for providing universal service. Other network service providers that do provide universal services make all or a portion of their “contribution” in the form of expenses related to the universal services they provide.

Foreign Ownership and Investment Restrictions and Requirements

Because we are a network service provider, and the exception for the foreign shareholding limit under the amended Telecommunications Business Act which became effective on August 13, 2013, does not apply to us, foreign governments, individuals, and entities (including Korean entities that are deemed foreigners, as discussed below) are prohibited from owning more than 49.0% of our voting stock. Korean entities whose largest shareholder is a foreign government or a foreigner (together with any of its related parties) that owns 15.0% or more of the outstanding voting stock of such Korean entities are also deemed foreigners. If this 49.0% ownership limitation is violated, certain of our foreign shareholders will not be permitted to exercise voting rights in excess of the limitation, and the MSIT may require other corrective action.

Notwithstanding the above, pursuant to a recentan amendment to the Telecommunications Business Act which became effective onin April 20, 2022, a Korean entity, so long as (i) such entity’s largest shareholder (determined by aggregating the shareholdings of such shareholder and its related parties) is a foreign entity specifically designated by the MSIT incorporated in a country that has entered into a bilateral or multilateral free trade agreement with Korea, and (ii) such shareholder (together with the shareholdings of its related parties) owns 15.0% or more of the issued voting stock of such entity, may own more than 49.0% of our issued shares but may not exercise its voting rights with respect to the shares held in excess of the 49.0% ceiling until the end of the MSIT’s Public Interest Review.

Moreover, while there is currently a pending bill before the National Assembly which proposes to eliminate such limitation on the aggregate foreign ownership, it remains uncertain as to whether the National Assembly will vote in favor of passing such bill or when such vote will take place.

As of December 31, 2021,2023, SK Inc. owned 65,668,397shares of our common stock, or 30.0%, of our issued shares. As of December 31, 2021,2023, the two largest foreign shareholders of SK Inc. each held a 3.3% stake therein. If such foreign shareholders increase their shareholdings in SK Inc. to 15% or more and any such foreign shareholder constitutes the largest shareholder of SK Inc., SK Inc. will be considered a foreign shareholder, and its shareholding in us would be included in the calculation of our aggregate foreign shareholding. If SK Inc.’s shareholding in us is included in the calculation of our aggregate foreign shareholding, then our aggregate foreign shareholding, assuming the foreign ownership level as of December 31, 20212023 (which we believe was 43.6%41.0%), would reach 73.6%, exceedingexceed the 49.0% ceiling on foreign shareholding.

If our aggregate foreign shareholding limit is exceeded, the MSIT may issue a corrective order to us, the breaching shareholder (including SK Inc. if the breach is caused by an increase in foreign ownership of SK Inc.) and the foreign shareholder which owns in the aggregate 15.0% or more of SK Inc. Furthermore, SK Inc. will be prohibited from exercising its voting rights with respect to the shares held in excess of the 49.0% ceiling, which

47


may result in a change in control of us. In addition, the MSIT will be prohibited from granting us licenses or permits necessary for entering into new telecommunications businesses until our aggregate foreign shareholding is reduced to below 49.0%. If a corrective order is issued to us by the MSIT arising from the violation of the foregoing foreign ownership limit, and we do not comply within the prescribed period under such corrective order, the MSIT may:

revoke our business license;

suspend all or part of our business; or

if the suspension of business is deemed to result in significant inconvenience to our customers or to be detrimental to the public interest, impose a
one-time
administrative penalty of up to 3.0% of the average of our annual revenue for the preceding three fiscal years.

if the suspension of business is deemed to result in significant inconvenience to our customers or to be detrimental to the public interest, impose a one-time administrative penalty of up to 3.0% of the average of our annual revenue for the preceding three fiscal years.

Additionally, the Telecommunications Business Act also authorizes the MSIT to assess monetary penalties of up to 0.3% of the purchase price of the shares for each day the corrective order is not complied with, as well as a prison term of up to three years or a penalty of Won 150 million. See “Item 3.D. Risk Factors — Risks Relating to Our Business — If SK Inc. causes us to breach the foreign ownership limitations on our common shares, we may experience a change of control.”

We are required under the Foreign Exchange Transaction Act to file a report with a designated foreign exchange bank or with the MOEF, in connection with any issue of foreign currency denominated securities by us in

44

Table of Contents
foreign countries. Issuances of US$30 million or less require the filing of a report with a designated foreign exchange bank, and issuances that are over US$30 million in the aggregate within one year from the filing of a report with a designated foreign exchange bank require the filing of a report with the MOEF.

The Telecommunications Business Act provides for the creation of a Public Interest Review Committee under the MSIT to review investments in or changes in the control of network service providers. The following events would be subject to review by the Public Interest Review Committee:

the acquisition by an entity (and its related parties) of 15.0% or more of the equity of a network service provider;

a change in the largest shareholder of a network service provider;

agreements by a network service provider or its shareholders with foreign governments or parties regarding important business matters of such network service provider, such as the appointment of officers and directors and transfer of businesses;

a deemed foreigner (as discussed above) from a country whose government has entered into a bilateral or multilateral free trade agreement designated by the MSIT with the Government owning in excess of 49.0% of the outstanding voting stock of a network service provider (which became effective on April 20, 2022);provider; and

a change in the shareholder that actually controlscontrol over a network service provider.provider specified in the Enforcement Decree of the Telecommunications Business Act (including, but not limited to, the change of control over the holding company of such network service provider).

If the Public Interest Review Committee determines that any of the foregoing transactions or events would be detrimental to the public interest, then the MSIT may issue orders to stop the transaction, amend any agreements, suspend voting rights, or divest the shares of the relevant network service provider. Additionally, if a dominant network service provider (which would currently include us and KT), together with its specially related persons (as defined under the FSCMA), holds more than 5.0% of the equity of another dominant network service provider, the voting rights on the shares held in excess of the 5.0% limit may not be exercised.

Operating Results

Unless otherwise indicated, the amounts set forth below in this Item 5.A. exclude the results of operations of our former businesses comprising the

Spin-off
Businesses, which are classified as discontinued operations. See “Item 4.A. History and Development of the Company” and “— Overview.”

Table of Contents

Overview

Our operations are reported in three segments: (1) cellular services, which include wireless voice and data transmission services, sales of wireless devices, IoT solutions and platform services as well as certain other new growth businesses and other miscellaneous cellular services,

(2) fixed-line
telecommunication services, which include
fixed-line
telephone services, broadband Internet services, advanced media platform services (including IPTV and cable TV services) and business communications services, and (3) other businesses, which include our
T-commerce,
portal service, and certain other miscellaneous businesses that do not meet the quantitative thresholds to be separately considered reportable segments.

In our cellular services segment, we earn revenue principally from our wireless voice and data transmission services through monthly

plan-based
fees, usage charges for outgoing voice calls, usage charges for wireless data services and
value-added
service fees paid by our wireless subscribers as well as interconnection fees paid to us by other telecommunications operators for use of our wireless network by their customers and subscribers. We also derive revenue from sales of wireless devices by PS&Marketing. Other sources of revenue include revenue from our IoT solutions and platform services, including AI solutions, as well as other miscellaneous cellular services and our new services and products utilizing our AI and digital infrastructure capabilities and our telecommunications platforms, including a broad range of IoT solutions, platform services, cloud services, smart factory solutions, subscription services, advertising and curated shopping services, metaverse platform-based services, AI solutions and enterprise AI services.

In our

fixed-line
telecommunication services segment, we earn revenue principally from our
fixed-line
telephone services and broadband Internet services and advanced media platform services (including IPTV and cable TV services) through monthly
plan-based
fees and usage charges as well as interconnection fees paid to us by other telecommunications operators for use of our
fixed-line
network by their customers and subscribers.subscribers, and advertising fees paid to us by businesses that advertise their products and services on our advanced media platforms. In addition, we derive revenue from international calling services and our business communications services through customized fee arrangements with our business customers. Following the Tbroad Merger in April 2020, the cable TV and broadband Internet services of the former Tbroad have become a part of our fixed-telecommunication services segment.

In our others segment, we principally earn revenue from the

T-commerce
business of SK Stoa, which derives revenue through
third-party
seller fees earned (including commissions) for transactions in which it acts as a selling agent on SK stoa, its
T-commerce
network, and our “Nate” portal service operated by SK Communications.
Communications and online corporate employee benefit management and training services provided by SK M&Service, which we acquired in February 2022.

Pursuant to the

Spin-off,
our former businesses comprising the
Spin-off
Businesses were transferred to SK Square, including businesses that were included in our former security services segment, former commerce segment and a substantial majority of the businesses that were formerly part of our others segment for the years ended December 31, 2019 and 2020, and such businesses have been accounted for as discontinued operations in our consolidated financial statements as of and for the year ended December 31, 2021 included in this annual report. Similarly, our consolidated statements of income for the years ended December 31, 2019 and 2020 included in this annual report have been restated to present such businesses as discontinued operations. See “Certain Defined Terms and Conventions Used in this Annual Report.” As a result, our former security services segment and commerce services segment were eliminated from our operating segments, and SK Stoa’s
T-commerce
business (which was previously part of our former commerce services segment) was reclassified as part of our others segment for the year ended December 31, 2021. The breakdown of our results of operations by operating segment for the years ended December 31, 2019 and 2020 in our consolidated audited financial statements have been recast to retroactively apply such changes in segmentation.

Our cellular service revenue and

fixed-line
telecommunications service revenue depend principally upon the number of our subscribers, the rates we charge for our services, the frequency and volume of subscriber usage of our services and the terms of our interconnection with other telecommunications operators. Our others revenue depends principally upon the gross merchandise volume, which is the total monetary value of customer purchases of goods and services, net of estimated refunds, of SK stoa and the number of merchants that utilize SK stoa and the Nate Portal to advertise and promote their products and services and the extent of such advertisement and promotion.

Among other factors, management uses operating profit of each reportable segment presented in accordance with

K-IFRS
(“ (“segment operating profit”) in its assessment of the profitability of each reportable segment. The sum
47

Table of Contents
of segment operating profit for all three reportable segments differs from our operating profit presented in accordance with IFRS as issued by the IASB as segment operating profit does not include certain items such as donations, gain and loss from disposal of property and equipment and intangible assets and impairment loss on property and equipment and intangible assets. For a reconciliation of operating profit presented in accordance with IFRS as issued by the IASB and operating profit presented in accordance with
K-IFRS,
see “— Explanatory Note Regarding Presentation of Certain Financial Information under
K-IFRS.”
In addition to the information set forth below, see note 4 of the notes to our consolidated financial statements for more detailed information regarding each of our reportable segments.

A number of recent developments have had or are expected to have a material impact on our results of operations, financial condition and capital expenditures. These developments include:

Rate Regulations

. Under the MDDIA, wireless telecommunications service providers are obliged to provide certain benefits, such as discounted rates, to subscribers who subscribe to their service without receiving handset subsidies. Handset subsidies are provided to subscribers who agree to use our service for a predetermined service period and purchase handsets on an installment basis. In June 2017, the State Affairs Planning Advisory Committee of Korea announced that it would encourage wireless telecommunications service providers, including us, to increase the applicable discount rate offered to subscribers from 20% to 25%, which we adopted in September 2017, and to offer additional discounts to low income customers, including those on government welfare programs and senior citizen recipients of the basic pension, which we implemented in December 2017 and July 2018, respectively. While the Government indicated in January 2024 that it will seek to abolish the MDDIA in order to encourage wireless service providers to offer more differentiated customer benefits to consumers, it has also suggested that such discounted rates may be retained through a related amendment to the

51


Telecommunications Business Act. In connection with such policy objectives, the Government amended the Enforcement Decree of the MDDIA in March 2024, pursuant to which wireless telecommunications service providers may provide more liberal subsidies to subscribers that are switching their wireless telecommunications providers based on certain criteria specified by the KCC, including the expected profits to the wireless telecommunications service providers and subscribers’ costs of switching wireless telecommunications service providers.

These Government measures have adversely affected our revenues and results of operations as more subscribers elected to receive the 25% rate discount in recent years. On the other hand, this has also led to a reduction of, or partially offset increases in, our marketing expenses as the number of subscribers who have elected to receive handset subsidies has generally declined in recent years, and has contributed to maintaining a stable churn rate.

Moreover, in light of the recent amendment to the Enforcement Decree of the MDDIA and the Government’s intent to ultimately abolish the MDDIA as discussed above, we may be required to increase our marketing expenses relating to handset subsidies in part depending on the prevailing competitive landscape, which may have an adverse effect on our operating expenses and results of operations.

Failure to comply with the MDDIA may lead to suspension of our business or imposition of monetary penalties. For more information about the MDDIA and the penalties imposed for violating Government regulations, see “Item 4.B. Business Overview — Law and Regulation — Rate Regulation” and “Item 8.A. Consolidated Statements and Other Financial Information — Legal Proceedings — KCC Proceedings.Regulation.

Decrease in Interconnection Fees

. Our wireless telecommunications services depend, in part, on our interconnection arrangements with domestic and international
fixed-line
and other wireless networks. Charges for interconnection affect our revenues and operating results. The MSIT determines the basic framework for interconnection arrangements, including policies relating to interconnection rates in Korea. Under our interconnection agreements, we are required to make payments in respect of calls which originate from our networks and terminate in the networks of other Korean telecommunications operators, and the other operators are required to make payments to us in respect of calls which originate in their networks and terminate in our network. The MSIT has continued to gradually decrease the interconnection rates in Korea, which has led to an overall decrease in our interconnection revenue as well as interconnection expenses from 2012 to 20212023 and any further reduction in interconnection rates by the MSIT may continue to impact our results of operations. Beginning in 2017, a single interconnection rate paid by fixed-line network service providers for fixed-line to wireless calls applies to all wireless telecommunications service providers. For more information about our interconnection revenue and expenses, see “Item 4.B. Business Overview — Interconnection.”
Fluctuations

Changes in Monthly Revenue per Subscriber

. We measure monthly average revenue per subscriber using two metrics: average monthly revenue per subscriber excluding MVNO subscribers leasing our networks (“ARPU”) and average monthly revenue per subscriber including such MVNO subscribers (“ARPU including MVNO”). ARPU is derived by dividing the sum of total SK Telecom revenues on a separate basis from voice service and data service for the period (excluding revenue derived from MVNO subscribers leasing our networks) by the monthly average number of subscribers (excluding the number of MVNO subscribers) for the period, then dividing that number by the number of months in the period. ARPU including MVNO is derived by dividing the sum of total SK Telecom revenues on a separate basis from voice service and data service for the period (including revenue derived from MVNO subscribers) by the monthly average number of subscribers (including the number of MVNO subscribers) for the period, then dividing that number by the number of months in the period.

Our ARPU increaseddecreased by 0.7%2.2% to Won 30,51729,874 in 20212023 from Won 30,31430,546 in 2020, which represented a decrease of 1.0% from Won 30,630 in 2019. Our ARPU including MVNO increased by 2.1% to Won 28,485 in 2021 from Won 27,895 in 2020,2022, which represented an increase of 1.8%0.1% from Won 27,41230,517 in 2019.2021. Our ARPU including MVNO decreased by 2.4% to Won 27,885 in 2023 from Won 28,582 in 2022, which represented an increase of 0.3% from Won 28,485 in 2021. The decrease in ARPU in 20202023 was primarily due to an increase in subscriptions for IoT solutions by corporate customers,and other non-mobile phone devices, from which we derive lower revenue per subscriber. Such decreases weresubscriber, which effect was offset in part by an increase in the number of subscribers that subscribe to our 5G subscription plans, which are relatively higher-priced unlimited data usage plans and 5Gcompared to other

types of wireless subscription plans. The increasedecrease in ARPU including MVNO in 20202023 was primarily attributabledue to the decreasean increase in the proportionnumber of MVNO subscribers from whom we derive lower revenue per subscriber.ARPU. The increases in our ARPU and our ARPU including MVNO in 20212022 were primarily due to an increase in the number of subscribers who subscribe to our higher-priced 5G subscription plans.

Effects of

COVID-19
and Economic Conditions in Korea. Demand for our products and services may fluctuate in light of the overall economic conditions in Korea. The overall prospects for the Korean economy and, in turn, the market conditions for the industries in which we operate, remain uncertain, especiallyand have been affected by, among others, the COVID-19 pandemic, Russia’s invasion of Ukraine and ensuing sanctions against Russia, difficulties faced by several banks in light of the ongoing global
COVID-19
pandemic,United States and Europe, rapid increases in policy interest rates globally (including Korea) to combat rising inflationary pressures, and more recently, escalating hostilities in the Middle East following the Israel-Hamas war, which has had,have adversely affected, and will likelymay continue to have, a significant negative effect onadversely affect, the Korean economy. For example, the travel restrictions imposed by governments in response to the
COVID-19
pandemic have resulted in a significant decrease in revenue from roaming services in 2021 before it increased significantly in 2022 and 2023 in light of the substantial lifting of such travel restrictions in most countries, and the pandemic has contributed to lower customer demand for new wireless devices, resulting in a decrease in our wireless device sales revenue.revenue in 2021 before it slightly increased in 2022 and continued to increase in 2023 as the negative effects of the COVID-19 pandemic have largely tapered. In addition, an increase in unemployment among, and/or a decrease in disposable income of, our customers resulting from amixed signs of deterioration ofand uncertain recovery displayed by the Korean economy due to
COVID-19
as described above, may decrease demand for some of our products and services or cause an increase in delinquent subscriber accounts. While it is not possible to predictA future recurrence of COVID-19, other types of widespread infectious diseases or other developments adversely affecting the duration or full magnitude of harm from
COVID-19,
a continued and prolonged outbreak of
COVID-19
Korean economy may have a material adverse effect on our business, financial condition and results of operations. See “Item 3.D. Risk Factors — Risks Relating to Our Business — The ongoing global pandemicOccurrences of

-

Wireless service revenue increased by 0.7% to Won 10,329.0 billion in 2023 from Won 10,253.2 billion in 2022, primarily attributable to the continued increase in the number of subscribers who subscribe to our 5G subscription plans and an increase in the usage of our roaming services in light of a further increase in international travel by our subscribers as the negative effects of the COVID-19 pandemic continued to taper.

-

Wireless device sales revenue increased by 2.6% to Won 993.9 billion in 2023 from Won 969.0 billion in 2022, primarily due to an increase in the average prices of the handsets we sold during the year, which primarily reflected the higher prices charged by device manufacturers in part due to higher manufacturing costs, partially offset by a decrease in the sales of handsets due to demand for new flagship devices of the leading device manufacturers falling short of expectations in 2023.

-

Cellular interconnection revenue decreased by 8.2% to Won 432.7 billion in 2023 from Won 471.2 billion in 2022, primarily attributable to a decrease in interconnection rates.

Revenue from our broadband Internet service and advanced media platform service (including our IPTV and cable TV services) increased by 1.7% to Won 2,494.0 billion in 2023 from Won 2,452.5 billion in 2022, primarily due to increases in the number of IPTV subscribers to 6.7 million subscribers as of December 31, 2023 from 6.5 million subscribers as of December 31, 2022 and the number of subscribers who subscribe to our higher-priced subscription plans.

-

International calling service revenue increased by 5.6% to Won 190.9 billion in 2023 from Won 180.7 billion in 2022, primarily due to an increase in international calling volume.

-

Fixed-line telephone service revenue decreased by 5.7% to Won 147.7 billion in 2023 from Won 156.7 billion in 2022, primarily due to decreases in residential calling volume as a result of a continued shift in consumer preference toward wireless communication and the number of fixed-line telephone subscribers to 3.46 million as of December 31, 2023 from 3.56 million as of December 31, 2022.

Our consolidated operating revenue increased by 4.4% to Won 16,087.7 billion in 2020 from Won 15,416.4 billion in 2019, primarily due to increases in fixed-line telecommunications services revenue and cellular services revenue, and to a smaller extent, increases in others revenue.
Our consolidated other income increased slightly by 0.2% to Won 95.8 billion in 2020 from Won 95.6 billion in 2019.
The following sets forth additional information about our operating revenues with respect to each of our reportable segments.
Cellular services: The revenue of our cellular services segment, which is composed of revenues from wireless service, cellular interconnection, wireless device sales and miscellaneous cellular services, increased by 1.0% to Won 12,348.0 billion in 2020 from Won 12,223.8 billion in 2019. The increase in our cellular services revenue was due to increases in wireless service revenue and miscellaneous revenue, in significant part offset by decreases in wireless device sales revenue and cellular interconnection revenue.

Table of Contents
Wireless service revenue increased by 2.8% to Won 9,806.7 billion in 2020 from Won 9,538.2 billion in 2019, primarily attributable to an increase in the number of subscribers who subscribe to our higher-priced 5G plans. The impact of such increase was partially offset by an increase in the cumulative percentage of wireless service subscribers who elected to receive discounted rates in lieu of receiving handset subsidies pursuant to the MDDIA as well as a decrease in MVNO subscribers.
Miscellaneous cellular services revenue increased by 4.4% to Won 1,085.7 billion in 2020 from Won 1,040.1 billion in 2019, primarily due to an increase in revenue from our IoT solutions business.
Wireless device sales revenue decreased by 14.6% to Won 983.4 billion in 2020 from Won 1,151.2 billion in 2019, primarily due to a decrease in sales of handsets as a result of lower customer demand for new devices, which was partly attributable to the
COVID-19
pandemic.
Cellular interconnection revenue decreased by 4.5% to Won 472.2 billion in 2020 from Won 494.3 billion in 2019. The decrease was primarily attributable to continued decreases in interconnection rates and
land-to-mobile
call volume.
Fixed-line
telecommunications services: The revenue of our
fixed-line
telecommunication services segment, which is composed of revenues from broadband Internet service and advanced media platform service (including IPTV and cable TV services),
fixed-line
telephone service, international calling service,
fixed-line
interconnection and miscellaneous
fixed-line
telecommunication services, increased by 16.0% to Won 3,432.2 billion in 2020 from Won 2,959.3 billion in 2019, primarily due to increases in our broadband Internet service and advanced media platform service revenue and miscellaneous fixed-line telecommunication services revenue, in small part offset by a decrease in fixed-line interconnection revenue.
Revenue from our broadband Internet service and advanced media platform service (including our IPTV and cable TV services) increased by 21.3% to Won 2,210.7 billion in 2020 from Won 1,822.4 billion in 2019, primarily due to the inclusion of revenue of the former Tbroad following the Tbroad Merger as well as an increase in the number of IPTV subscribers to 5.7 million subscribers as of December 31, 2020 from 5.2 million subscribers as of December 31, 2019.
Miscellaneous
fixed-line
telecommunication services revenue increased by 9.7% to Won 747.0 billion in 2020 from Won 681.0 billion in 2019, primarily due to an increase in revenue from our business communications services.
Fixed-line
interconnection revenue decreased by 9.3% to Won 83.8 billion in 2020 from Won 92.4 billion in 2019, primarily due to a decrease in interconnection rates, as well as decreases in the number of fixed-line telephone subscribers and residential calling volume.
Others: The revenue of our others segment increased by 31.8% to Won 307.6 billion in 2020 from Won 233.3 billion in 2019, primarily due to a 40.2% increase in SK Stoa’s
T-commerce
business to Won 268.5 billion in 2020 from Won 191.5 billion in 2019, which mainly reflected an increase in the volume of merchandise sold.
Operating Expenses.
Our consolidated operating expenses increased by 4.3% to Won 15,148.5 billion in 2020 from Won 14,525.0 billion in 2019, primarily due to a 7.1% increase in commissions to Won 5,103.0 billion in 2020 from Won 4,766.7 billion in 2019, a 17.6% increase in other operating expenses to Won 1,658.4 billion in 2020 from Won 1,410.3 billion in 2019, a 6.4% increase in labor costs to Won 2,108.5 billion from Won 1,981.9 billion in 2019 and a 3.5% increase in depreciation and amortization expenses to Won 3,664.7 billion in 2020 from Won 3,541.0 billion in 2019, partially offset by a 19.7% decrease in cost of goods sold to Won 1,106.0 billion in 2020 from Won 1,378.1 billion in 2019.
The increase in commissions was primarily due to the inclusion of commissions of the former Tbroad following the Tbroad Merger in April 2020.
56

Table of Contents
The increase in other operating expenses was primarily due to an increase in impairment loss on property and equipment and intangible assets to Won 200.7 billion in 2020 from Won 42.8 billion in 2019, which amount in 2020 mainly reflected impairment losses we recognized on frequency usage rights.
The increase in labor costs was primarily due to the additional personnel on payroll in connection with the Tbroad Merger.
The increase in depreciation and amortization expenses was primarily related to our equipment and frequency usage rights for our 5G network.
The decrease in cost of goods sold was primarily due to a decrease in the number of wireless devices sold in 2020.
The following sets forth additional information about our segment operating expenses with respect to each of our reportable segments, which do not include certain expenses that are classified as other
non-operating
expenses under
K-IFRS.
For more information on the difference between our consolidated operating expenses pursuant to
K-IFRS
and pursuant to IFRS as issued by the IASB, see “— Explanatory Note Regarding Presentation of Certain Financial Information under
K-IFRS”
and note 4(2) of the notes to our consolidated financial statements.
Cellular services: The segment operating expenses for our cellular services segment slightly increased by 0.1% to Won 11,341.2 billion in 2020 from Won 11,327.7 billion in 2019, mainly attributable to an increase in marketing costs to promote our 5G services and increases in depreciation and amortization expenses of our equipment and frequency usage rights for our 5G network.
Fixed-line
telecommunication services: The segment operating expenses for our
fixed-line
telecommunication services segment increased by 13.8% to Won 3,189.3 billion in 2020 from Won 2,802.0 billion in 2019, primarily due to the inclusion of operating expenses of the former Tbroad following the Tbroad Merger.
Others: The segment operating expenses for our others segment increased by 24.4% to Won 308.6 billion in 2020 from Won 248.0 billion in 2019, primarily due to an increase in the cost of sales of SK Stoa, which mainly reflected a corresponding increase in the revenue generated by SK Stoa’s
T-commerce
business.
Operating Profit.
Our consolidated operating profit increased by 4.9% to Won 1,035.0 billion in 2020 from Won 987.1 billion in 2019, as the increase in operating revenue and other income outpaced the increase in operating expenses in 2020.
The following sets forth additional information about our segment operating profit (loss) with respect to each of our reportable segments. Our segment operating profit (loss) with respect to each of our reportable segments is based on
K-IFRS
and the sum of segment operating profit for all three reportable segments differs from our consolidated operating profit presented in accordance with IFRS as issued by the IASB. For a reconciliation of operating profit presented in accordance with IFRS as issued by the IASB and operating profit presented in accordance with
K-IFRS,
see “— Explanatory Note Regarding Presentation of Certain Financial Information under
K-IFRS”
and note 4(2) of the notes to our consolidated financial statements.
Cellular services: The segment operating profit of our cellular services segment increased by 12.4% to Won 1,006.8 billion in 2020 from Won 896.1 billion in 2019, due to the greater increase in segment operating revenue as compared to the increase in segment operating expenses, for the various reasons described above.
The segment operating margin (which, with respect to each reportable segment, is segment operating profit (loss) divided by revenue from such segment, expressed as a percentage) of our cellular services segment increased to 8.2% in 2020 from 7.3% in 2019.
Fixed-line
telecommunication services: The segment operating profit of our
fixed-line
telecommunication services segment increased by 54.4% to Won 242.9 billion in 2020 from Won 157.3 billion in 2019, mainly due to the aggregate impact of the Tbroad Merger as described above.
As a result, the segment operating margin of our
fixed-line
telecommunication services segment increased to 7.1% in 2020 from 5.3% in 2019.
Others: The segment operating loss of our others segment significantly decreased by 92.5% to Won 1.1 billion in 2020 from Won 14.7 billion in 2019, due to the greater increase in segment operating revenue

as compared to the increase in segment operating expenses as described above. As a result, the segment operating margin of our others segment improved to (0.4)% in 2020 from (6.3)% in 2019.
Finance Income and Finance Costs.
Our finance income increased by 15.6% to Won 140.7 billion in 2020 from Won 121.7 billion in 2019, primarily due to an 83.7% increase in gain relating to financial instruments at fair value through profit or loss to Won 63.0 billion in 2020 from Won 34.3 billion in 2019, primarily relating to shares of Oceanbridge Co., Ltd. held by Quantum Innovation Fund I. The effect of such increase was partially offset by a 23.9% decrease in interest income to Won 37.0 billion in 2020 from Won 48.6 billion in 2019, mainly reflecting a decrease in interest rates.
Our finance costs decreased by 3.6% to Won 322.9 billion in 2020 from Won 334.9 billion in 2019, primarily due to a decrease in interest expense to Won 289.0 billion in 2020 from Won 306.7 billion in 2019 as a result of a decrease in interest rates, as well as a loss on sale of other accounts receivable related to handset installment payments of Won 5.8 billion in 2019 compared to no such loss in 2020. The effect of such decreases was partially offset by a 70.4% increase in loss relating to financial instruments at fair value through profit or loss to Won 13.8 billion in 2020 from Won 8.1 billion in 2019 mainly related to our investments in certain fund products.
Gains (Losses) Related to Investments in Associates and Joint Ventures.
Gains related to investments in associates and joint ventures increased by 58.1% to Won 52.5 billion in 2020 from Won 33.2 billion in 2019, primarily due to an increase in our share of profits of KEB HanaCard.
Income Tax.
Income tax expense decreased by 15.8% to Won 221.3 billion in 2020 from Won 262.9 billion in 2019 notwithstanding a 12.2% increase in profit before income tax to Won 905.2 billion in 2020 from Won 807.0 billion in 2019 mainly due to changes in unrecognized deferred taxes and tax credits and tax reductions.
Our effective tax rate in 2020 decreased to 24.4% from 32.6% in 2019. Our effective tax rate in 2020 was lower than the maximum statutory tax rate of 27.5%, primarily due to changes in unrecognized deferred taxes and tax credits and tax reductions. Our effective tax rate in 2019 was higher than the maximum statutory tax rate of 27.5%, also primarily due to changes in unrecognized deferred taxes.
Profit from Continuing Operations.
Principally as a result of the factors discussed above, our profit from continuing operations increased by 25.7% to Won 684.0 billion in 2020 from Won 544.1 billion in 2019.
Profit from Discontinued Operations.
Our profit from discontinued operations, net of taxes, increased by 157.9% to Won 816.6 billion in 2020 from Won 316.6 billion in 2019, primarily due to an increase in our share of profits of SK Hynix, our equity interest in which was transferred to SK Square as of November 1, 2021 pursuant to the
Spin-off.
Profit for the Year.
Principally as a result of the factors discussed above, our profit for the year increased by 74.3% to Won 1,500.5 billion in 2020 from Won 860.7 billion in 2019. Profit for the year as a percentage of operating revenue and other income was 9.3% in 2020 compared to 5.5% in 2019.

For the presentation of the statement of cash flows for the year ended December 31, 2021 in our consolidated financial statements, we elected to combine cash flows from discontinued operations with cash flows from continuing operations within each cash flow statement category. The absence of cash flows from discontinued operations is not expected to affect our future liquidity and capital resources.

Cash flows from operating activities and debt financing have been our principal sources of liquidity. We had cash and cash equivalents of Won 1,455.0 billion as of December 31, 2023, Won 1,882.3 billion as of December 31, 2022 and Won 872.7 billion as of December 31, 2021 and Won 1,369.7 billion as of December 31, 2020.2021. We believe that we have a variety of alternatives available to us to satisfy our financial requirements to the extent that they are not met by funds generated by operations, including the issuance of debt securities and bank borrowings.

spin-off
were Won 626.0 billion in 2021.

As of December 31, 2021,2023, we had total long termlong-term debt (excluding current portion) outstanding of Won 7,390.57,421.9 billion, which included debentures in the amount of Won 7,037.47,106.3 billion and bank and institutional borrowings in the amount of Won 353.1315.6 billion. As of December 31, 2020,2022, we had total

long-term
debt (excluding current portion) outstanding of Won 9,669.47,192.2 billion, which included debentures in the amount of Won 7,690.26,524.1 billion and bank and institutional borrowings in the amount of Won 1,979.3668.1 billion. For a description of our
long-term
debt, see note 18 of the notes to our consolidated financial statements.

As of December 31, 2021,2023, we had (i) Won 6,670.07,000.0 billion aggregate principal amount of Korean

Won-denominated
debentures outstanding, of which SK Telecom issued Won 5,400.05,780.0 billion and SK Broadband issued Won 1,270.01,220.0 billion, and (ii) Won 1,778.21,351.3 billion aggregate principal amount of debentures outstanding denominated in U.S. dollars. The fixed interest rates of our debentures range from 1.17% to 6.63% depending on the offering size, maturity, interest rate environment at the time of the offering and currency, among other factors. We have a diversified maturity profile with respect to our debentures. See “— Contractual Obligations and Commitments” for more details.

As of December 31, 2021,2023, substantially all of our foreign

currency-denominated
long-term
borrowings and debentures, which in the aggregate amounted to 20.4%14.8% of our total outstanding
long-term
debt, including the current portion and net of present value discount and discounts on bonds as of such date, was denominated in Dollars. However, substantially all of our revenue and operating expenses are denominated in Won. We generally pay for imported capital equipment in Dollars. Appreciation of the Won against the Dollar will result in net foreign currency transaction and translation gains, while depreciation of the Won against the Dollar will result in net foreign currency transaction and translation losses. Changes in foreign currency exchange rates will also affect our liquidity because of the effect of such changes on the amount of funds required for us to make interest and principal payments on our foreign

Capital Requirements

Historically, capital expenditures, repayment of outstanding debt, frequency usage payments and lease payments have represented our most significant use of funds. In recent years, we have also increasingly dedicated

65


capital resources to develop and invest in new ICT businesses (some of which were transferred to SK Square as of November 1, 2021 pursuant to the

Spin-off)
as well as other innovative services and products utilizing our AI and digital infrastructure capabilities and our telecommunications platforms.

To fund our scheduled debt repayment and planned capital expenditures over the next several years, we intend to rely primarily on cash flows from operating activities, as well as bank and institutional borrowings, and offerings of debt or equity in the domestic or international markets. We believe that these sources will be sufficient to fund our planned capital expenditures for 2022.

2024.Our ability to rely on these alternatives could be affected by the liquidity of the Korean financial markets or by Government policies regarding Won and foreign currency borrowings and the issuance of equity and debt. Our failure to make needed expenditures would adversely affect our ability to sustain subscriber growth and provide quality services and, consequently, our results of operations.

Capital Expenditures.

The following table sets forth our actual capital expenditures for 2021, 20202023, 2022 and 2019,2021, in each case including capital expenditures relating to discontinued operations:

We set our capital expenditure budget for each upcoming year on an annual basis. Our actual capital expenditures in 2021, 20202023, 2022 and 20192021 were Won 2,915.92,973.9 billion, Won 3,557.82,908.3 billion and Won 3,375.92,915.9 billion, respectively. Of such amounts, we spent approximately 46.4%, 63.2% and 63.5%, 52.8% and 74.5% in 2021, 2020 and 2019, respectively, on capital expenditures related to building and enhancing our wireless networks. Our capital expenditures related to building and enhancing our wireless networks, including in connection with our 5G network which we launched in 2019, have generally decreased in recent years. See “Item 4.B. Business Overview — Cellular Services — Digital Wireless Network — 5G Network.” Our other

non-network
related capital expenditures in 2021, 20202023, 2022 and 20192021 primarily related to developing new products, services and technology, upgrades to our information technology systems and equipment and investments in data infrastructure, which included certain capital expenditures made in connection with our discontinued operations.

In particular, we have been making capital expenditures to buildfurther expand and expandimprove our 5G network. We commenced commercial 5G services in April 2019. We have also been making capital expenditures to maintain our LTE network.

For a more detailed description of our 5G and LTE networks, see “Item 4.B. Business Overview — Cellular Services — Digital Wireless Network.” We plan to continue to make capital investments in 20222024 to build and expand our 5G network and develop related technologies, as well as to further improve and maintain our LTE network.

We currently expect to spend a similar amount for capital expenditures in 20222024 compared to 20212023 for a range of projects, including investments to further expand and improve our newly implemented 5G network, investments to maintain our LTE network and

LTE-A
related services, investments to improve and expand our
Wi-Fi
network, investments to develop our IoT solutions and platform services business portfolio, including AI solutions, investments in data infrastructure, investments in further research and development of 5G technology, investments in businesses that can potentially leverage our 5G network, and investments in funding for

to long-term research and development projects. Such projects as well asalso include other initiatives primarily related to the development of new growth businesses as well as initiatives related toand our ongoing businesses in the ordinary course.course, in each case with an emphasis on incorporating AI technology into our various existing and new business areas. In November 2020,2021, the MSIT announced plans to reallocatereallocated a total of 310 MHz of frequency bandwidths whose usage terms were due to expire in 2021 to KT, LG U+ and us, 95 MHz of which in the 800 MHz, 2.1 GHz and 2.6 GHz spectrums was allocated to us in 2021.us. We would be required to spend additional amounts on capital expenditures in connection with buildingour continued efforts to build out our networks on such reallocated bandwidths.However, our overall expenditure levels and our allocation among projects remain subject to many uncertainties. We may increase, reduce or suspend our planned capital expenditures for 20222024 or change the timing and area of our capital expenditure spending from the estimates described above in response to market conditions or for other reasons. We may also make additional capital expenditureexpenditures and other investments beyond our currently anticipated level as opportunities arise.arise, including in relation to any acquisitions of additional frequency usage rights or execution of additional AI-related investments. Accordingly, we periodically review the amount of our capital expenditures and other investments and may make adjustments based on the current progress of capital expenditure projects and market conditions. No assurance can be given that we will be able to meet any such increased expenditure requirements or obtain adequate financing for such requirements, on terms acceptable to us, or at all.

Other Equity-based Compensation

PSU Program

Since 2023, we have been granting PSUs to certain of our and our subsidiaries’ directors (including the representative director) and executive officers in order to align management and shareholder interests and further align growth in our enterprise value with management compensation. Future performance targets are set when entering into the relevant stock compensation agreement, and the final number of shares to be received by each grantee, which will be settled out of our treasury shares, will be determined based on the achievement levels of such targets subject to approval by the board of directors. In consideration of the representative director’s role and importance, additional shares of up to 100% of the representative director’s annual salary at the time of the PSU grant may be granted in recognition of his or her outstanding achievements upon satisfaction of certain conditions. The validity of the PSUs, which is subject to a three-year vesting period, is dependent on the grantee meeting a minimum term of incumbency under his or her title until the end of the year in which the PSUs were issued. In 2023, we granted a total of 228,708 PSUs to 194 directors and executive officers.

Stock Appreciation Rights (“SARs”) Program

In 2021 and 2022, we granted SARs to certain of our executive officers as equity compensation. SARs entitle the grantee to receive in cash the product of (a) the difference between the base share price at the time of grant (calculated based on the arithmetic mean of the weighted average of recent share prices) and the base share price after a three-year vesting period (calculated based on the arithmetic mean of the weighted average of recent share prices), and (b) the number of shares of our common stock equal to 100% of a grantee’s annual salary. If the grantee’s employment with us is terminated within two years of the grant date, no such payment is made. If a grantee’s employment with us is terminated at a date between two and three years after the grant date, settlement is made based on the share price on the termination date. The maximum payout is capped at 100% of the grantee’s annual salary at the time of grant. In 2021, we granted a total of 253,081 SARs to 86 executive officers. In 2022, we granted a total of 338,525 SARs to 72 executive officers. In 2023, we did not grant any SARs.

Shareholder Participation Program

Since 2021, pursuant to the Korean Commercial Code, we have been operating the “Shareholder Participation Program” as equity compensation in order to align management and shareholder interests and strengthen commitment to enhance our enterprise value. All of our employees, including the representative director, are eligible to participate in the Shareholder Participation Program, under which we grant treasury shares equal to a portion of a participating employee’s bonus. The participating employee must be employed with us at the time of actual grant and there is no transfer restriction period. In 2021, we granted a total of 366,309 treasury shares (reflecting the effects of the Stock Split) to 1,985 employees. In 2022, we granted a total of 413,080 treasury shares to 2,005 employees. In 2023, we granted a total of 434,088 treasury shares to 1,863 employees.

Stock Grant Program

Since 2021, we have been granting portions of our independent non-executive directors’ remuneration in the form of shares in order to align the interests of our board of directors and shareholders. The number of shares granted, which is in the form of treasury shares, is based on the independent non-executive director’s role and responsibility and our director compensation payment criteria. Transfer of such shares is restricted for three years following initial receipt. In 2021, we granted a total of 1,515 treasury shares (reflecting the effects of the Stock Split) to five independent non-executive directors. In 2022, we granted a total of 5,984 treasury shares to five independent non-executive directors. In 2023, we granted a total of 6,999 treasury shares to five independent non-executive directors.

In addition, in 2021, we awarded a total of 1,531,210 treasury shares to 5,054 employees of SK Telecom in order to enhance our enterprise value and maximize synergies following the Spin-off. The treasury shares were granted to our then-current employees and the transfer of such shares was restricted for six months.

Employee Benefits

Since April 1999, we have been required to contribute an amount equal to 4.5% of employee wages toward a national pension plan. Employees are eligible to participate in an employee stock ownership association. We are not required to, and we do not, make any contributions to the employee stock ownership association, although we subsidize the employee stock ownership association through the Employee Welfare Fund by providing low interest rate loans to employees who desire to purchase our stock through the plan in the event of a capitalization by the association.

We are required to pay a severance amount to eligible employees who voluntarily or involuntarily cease employment with us, including through retirement. This severance amount is based upon the employee’s length of service with us and the employee’s salary level at the time of severance. AsThe present value of December 31, 2021, theour defined benefit obligation,obligations, which is the present value of total accrued and unpaid retirement and severance benefits for our employees, as of December 31, 2023, was Won 1,121.7 billion, which was more than offset by the fair value of our defined benefit plan assets of Won 1,035.01,292.4 billion for allas of our employees is reflected in our consolidated financial statements as a liability, of which a totalsuch date.

Under Korean laws and regulations, we are prevented from involuntarily terminating a full-time employee except under certain limited circumstances. In September 2000, we entered into an employment stabilization agreement with the union. Among other things, in the event that we reorganize a department into a separate entity or we outsource an employee to a separate entity where the wage is lower, this agreement provides for a guarantee of the same wage level for the year that such an event occurs.

Under the Basic Labor Welfare Act, we may also contribute up to 5.0% of our annual earnings before tax for employee welfare. Contribution amounts are determined annually following negotiation with the union. The contribution amount for 2023 was set at 4.58% of SK Telecom’s profit before income tax on a separate basis, or Won 62.0 billion.

Dividends

Annual dividends, if any, on our outstanding shares must be approved at the annual general meeting of shareholders. This meeting is generally held in March of the following year, and the annual dividend is generally paid shortly after the meeting. Since our shareholders have discretion to declare annual dividends, we cannot give any assurance as to the amount of dividends per share or that any dividends will be declared at all. Interim dividends, if any, could be approved by a resolution of our board of directors. We replaced the interim dividend system with a quarterly dividend system pursuant to an amendment to our articles of incorporation at our annual general meeting of shareholders held on March 25, 2021. Once declared, dividends must be claimed within five years, after which the right to receive the dividends is extinguished and reverted to us.

We pay cash dividends to the ADR depositary in Won. Under the terms of the deposit agreement, cash dividends received by the ADR depositary generally are to be converted by the ADR depositary into Dollars and distributed to the holders of the ADSs, less withholding tax, other governmental charges and the ADR depositary’s fees and expenses. The ADR depositary’s designated bank in Korea must approve this conversion and remittance of cash dividends. See “Item 10.D. Exchange Controls — Korean Foreign Exchange Controls and Securities Regulations.”

The following table sets forth the dividend per share and the aggregate total amount of dividends declared (including any interim dividends), as well as the number of outstanding shares entitled to dividends, with respect to the years ended December 31, 2019 and 2020.

Table of Contents

We distribute dividends to our shareholders in proportion to the number of shares owned by each shareholder. Our common shares represented by the ADSs have the same dividend rights as other outstanding common shares.

Holders of

non-voting
shares are entitled to receive dividends in priority to the holders of common shares. The dividend on the
non-voting
shares is between 9.0% and 25.0% of the par value as determined by the board of directors at the time of their issuance. If the dividends for common shares exceed the dividends for
non-voting
shares, the holders of
non-voting
shares will be entitled to participate in the distribution of such excess amount with the holders of common shares. If the amount available for dividends is less than the aggregate amount of the minimum required dividend, holders of
non-voting
shares will be entitled to receive such accumulated unpaid dividend from dividends payable in the next fiscal year before holders of common shares. There are no
non-voting
shares issued or outstanding.

87


We declare dividends annually at the annual general meeting of shareholders which is generally held within three months after the end of the fiscal year. We pay the annual dividend shortly after the annual general meeting to the shareholders of record or registered pledges as of the end of the preceding fiscal year. We may distribute the annual dividend in cash or in shares. However, a dividend of shares must be distributed at par value. Dividends in shares may not exceed

one-half
of the annual dividend. Our obligation to pay dividend expires if no claim to dividend is made for five years from the payment date.

Under the Korean Commercial Code, we may pay an annual dividend only out of the excess of our net assets, on a

non-consolidated
basis, over the sum of (1) our stated capital, (2) the total amount of our capital surplus reserve, (3) legal reserve accumulated up to the end of the relevant dividend period and (4) the increase in our net asset value resulting from the evaluation of our assets and liabilities that has not been offset against unrealized losses. In addition, we may not pay an annual dividend unless we have set aside as a legal reserve an amount equal to at least 10.0% of the cash portion of the annual dividend or until we have accumulated a legal reserve of not less than
one-half
of our stated capital. We may not use our legal reserve to pay cash dividends but may transfer amounts from our legal reserve to capital stock or use our legal reserve to reduce an accumulated deficit.

In addition, the FSCMA and our articles of incorporation provide that, in addition to annual dividends, we may pay quarterly dividends. Unlike annual dividends, the decision to pay quarterly dividends can be made by a resolution of the board of directors and is not subject to shareholder approval. Any quarterly dividends must be paid in cash to the shareholders of record as of March 31, June 30 or September 30 of the relevant fiscal year.

Under the FSCMA, the total amount of quarterly dividends payable in a fiscal year shall not be more than the net assets on the balance sheet of the immediately preceding fiscal year, after deducting (1) a company’s capital in the immediately preceding fiscal year, (2) the aggregate amount of its capital reserves and legal reserves accumulated up to the immediately preceding fiscal year, (3) the amount of earnings for dividend payments confirmed at the general shareholders’ meeting with respect to the immediately preceding fiscal year and (4) the amount of legal reserve that should be set aside for the current fiscal year following the quarterly dividend payment. Furthermore, the rate of quarterly dividends for

non-voting
shares must be the same as that for our common shares. In addition, no quarterly dividends can be paid if there is a concern over the net assets of the current fiscal year falling short of the aggregate sum of (1) our stated capital, (2) the total amount of our capital surplus reserve, (3) legal reserve accumulated up to the end of the current fiscal year and (4) the increase in our net asset value resulting from the evaluation of our assets and liabilities that has not been offset against unrealized losses.

Our obligation to pay quarterly dividends expires if no claims to such dividends are made for a period of five years from the payment date.

non-executive
directors is required for certain matters, which include:

82

Table of Contents

There are no specific shareholding requirements for director’s qualification. Directors are elected at a general meeting of shareholders if the approval of the holders of the majority of the voting shares present at such meeting is obtained and if such majority also represents at least

one-fourth
of the total number of shares outstanding. Under the Korean Commercial Code, unless otherwise stated in the articles of incorporation, holders of an aggregate of 1.0% or more of the outstanding shares with voting rights may request cumulative voting in any election for two or more directors. Our articles of incorporation do not permit cumulative voting for the election of directors.

The term of office for directors is until the close of the third annual general shareholders meeting convened after he or she commences his or her term. Our directors may serve consecutive terms and our shareholders may remove them from office at any time by a special resolution adopted at a general meeting of shareholders. The total term of office of independent directors may not exceed six years, and when combined with the term of office at our affiliates, may not exceed nine years.

Dividends

We distribute dividends to our shareholders in proportion to the number of shares owned by each shareholder. Our common shares represented by the ADSs have the same dividend rights as other outstanding common shares. For a detailed discussion of our dividend policy, see “Item 8.A. Consolidated Statements and Other Financial Information — Dividends.”

Distribution of Free Shares

In addition to paying dividends in shares out of our retained or current earnings, we may also distribute to our shareholders an amount transferred from our capital surplus or legal reserve to our stated capital in the form of free shares. We must distribute such free shares to all of our shareholders in proportion to their existing shareholdings.

Preemptive Rights and Issuance of Additional Shares

We may at times issue authorized but unissued shares, unless otherwise provided in the Korean Commercial Code, on terms determined by our board of directors. All of our shareholders are generally entitled to subscribe to any newly-issued shares in proportion to their existing shareholdings. We must offer new shares on uniform terms to all shareholders who have preemptive rights and are listed on our shareholders’ registry as of the relevant record date. We must give public notice of the preemptive rights regarding new shares and their transferability at least two weeks before the relevant record date. Our board of directors may determine how to distribute shares for which preemptive rights have not been exercised or where fractions of shares occur.

Under the Korean Commercial Code and our articles of incorporation, we may issue new shares pursuant to a board resolution to persons other than existing shareholders only if (1) the new shares are issued for the purpose of issuing depositary receipts in accordance with the relevant regulations or through an offering to public investors and (2) the purpose of such issuance is deemed necessary by us to achieve a business purpose, including, but not limited to, the introduction of new technology or the improvement of our financial condition. If we make an allotment of new shares to persons other than our existing shareholders, we are required by the Korean Commercial Code to notify our existing shareholders of (a) the class and number of new shares, (b) the

91


issuance price of new shares and the date set for the payment thereof, (c) in cases of no par value shares, the amount to be included in the

paid-up
capital out of the issuance price of new shares and (d) the method of subscription to new shares by no later than two weeks before the date of payment of the subscription price, or publicly announce such information. Under our articles of incorporation, only our board of directors is authorized to set the terms and conditions with respect to such issuance of new shares.

In addition, under our articles of incorporation, we may issue convertible bonds or bonds with warrants, each up to an aggregate principal amount of Won 400.0 billion, to persons other than existing shareholders, where such issuance is deemed necessary by us to achieve a business purpose, including, but not limited to, the introduction of new technology or the improvement of our financial condition.

Members of our employee stock ownership association, whether or not they are our shareholders, generally have a preemptive right to subscribe for up to 20.0% of the shares publicly offered pursuant to the FSCMA. This

83

Table of Contents
right is exercisable only to the extent that the total number of shares so acquired and held by members of our employee stock ownership association does not exceed 20.0% of the sum of the number of shares then outstanding and the number of newly-issued shares.

General Meeting of Shareholders

We generally hold the annual general meeting of shareholders within three months after the end of each fiscal year. Subject to a board resolution or court approval, we may hold an extraordinary general meeting of shareholders:

as necessary;

at the request of holders of an aggregate of 3.0% or more of our outstanding common shares;

at the request of shareholders holding an aggregate of 1.5% or more of our outstanding shares and preferred shares for at least six months; or

at the request of our audit committee.

Holders of

non-voting
preferred shares may request a general meeting of shareholders only after the
non-voting
shares become entitled to vote or “enfranchised,” as described under “— Voting Rights” below.

We must give shareholders written notice setting out the date, place and agenda of the meeting at least two weeks before the date of the general meeting of shareholders. However, for holders of less than 1.0% of the total number of issued and outstanding voting shares, we may give notice by placing at least two public notices in at least two daily newspapers at least two weeks in advance of the meeting. Currently, we use The Korea Economic Daily News and Maeil Business Newspaper, both published in Seoul, for this purpose, but we may give notice in the future through electronic means. Shareholders who are not on the shareholders’ registry as of the record date are not entitled to receive notice of the general meeting of shareholders or attend or vote at the meeting. Holders of

non-voting
preferred shares, unless enfranchised, are not entitled to receive notice of or vote at general meetings of shareholders.

Our general meetings of shareholders have historically been held in or near Seoul.

Voting Rights

Holders of our common shares are entitled to one vote for each common share, except that voting rights of common shares held by us (including treasury shares and shares held by bank trust funds controlled by us), or by a corporate shareholder in which we own more than 10.0% equity interest, either directly or indirectly, may not be exercised. The Korean Commercial Code, unless otherwise stated in the articles of incorporation, permits cumulative voting, which would allow each shareholder to have multiple voting rights corresponding to the

92


number of directors to be appointed in the voting and to exercise all voting rights cumulatively to elect one director. Our articles of incorporation do not permit cumulative voting for the election of directors.

Our shareholders may adopt resolutions at a general meeting by an affirmative majority vote of the voting shares present or represented at the meeting if such affirmative votes also represent at least

one-fourth
of our total voting shares then issued and outstanding. However, under the Korean Commercial Code and our articles of incorporation, the following matters, among others, require approval by the holders of at least
two-thirds
of the voting shares present or represented at a meeting, and such affirmative votes must also represent at least
one-third
of our total voting shares then issued and outstanding:

amending our articles of incorporation;

removing a director;

effecting any dissolution, merger or consolidation of us;

transferring the whole or any significant part of our business;

effecting our acquisition of all of the business of any other company or a part of the business of any other company having a material effect on our business;

84

Table of Contents

reducing our capital; or

issuing any new shares at a price lower than their par value.

In general, holders of

non-voting
preferred shares are not entitled to vote on any resolution or receive notice of any general meeting of shareholders.

However, in case of amendments to our articles of incorporation, or any merger or consolidation of us, or in some other cases which affect the rights or interests of the

non-voting
preferred shares, approval of the holders of
non-voting
preferred shares is required. We may obtain the approval by a resolution of holders of at least
two-thirds
of the
non-voting
preferred shares present or represented at a class meeting of the holders of
non-voting
preferred shares, where the affirmative votes also represent at least
one-third
of our total issued and outstanding
non-voting
shares. In addition, if we are unable to pay dividends on
non-voting
preferred shares as provided in our articles of incorporation, the holders of
non-voting
shares will become enfranchised and will be entitled to exercise voting rights beginning at the next general meeting of shareholders to be held after the declaration of
non-payment
of dividends is made until such dividends are paid. The holders of enfranchised
non-voting
preferred shares will have the same rights as holders of common shares to request, receive notice of, attend and vote at a general meeting of shareholders.

Shareholders may exercise their voting rights by proxy. A shareholder may give proxies only to another shareholder, except that a corporate shareholder may give proxies to its officers or employees.

Holders of ADRs exercise their voting rights through the ADR depositary, an agent of which is the record holder of the underlying common shares. Subject to the provisions of the deposit agreement, ADR holders are entitled to instruct the ADR depositary how to vote our common shares underlying their ADSs.

Limitation on Shareholdings

The Telecommunications Business Act prohibits foreign governments, individuals, and entities (including Korean entities that are deemed foreigners, as discussed below) from owning more than 49.0% of our voting stock, subject to certain exceptions. See “Item 4.B4.B. Business Overview — Foreign Ownership and Investment Restrictions and Requirements.” Korean entities whose largest shareholder is a foreign government or a foreigner (together with any of its related parties) that owns 15.0% or more of such Korean entities’ outstanding voting stock are deemed foreigners. A foreigner who has acquired shares of our voting stock in excess of such limitation may not exercise the voting rights with respect to the shares exceeding such limitation and may be subject to the MSIT’s corrective orders.

93


Rights of Dissenting Shareholders

Under Financial Investment Services and Capital Market Act, in some limited circumstances, including the transfer of all or a significant part of our business or our merger or consolidation with another company (with certain exceptions), dissenting shareholders have the right to require us to purchase their shares. To exercise this right, shareholders, including holders of

non-voting
shares, must submit to us a written notice of their intention to dissent before the general meeting of shareholders. Then, within 20 days after the relevant resolution is passed at a meeting, the dissenting shareholders must request us in writing to purchase their shares. We are obligated to purchase the shares of such dissenting shareholders within one month after the expiration of the
20-day
period. The purchase price for the shares is required to be determined through negotiation between the dissenting shareholders and us. If we cannot agree on a price through negotiation, the purchase price will be the average of (1) the weighted average of the daily share prices on the KRX KOSPI Market for the
two-month
period before the date of the adoption of the relevant board resolution, (2) the weighted average of the daily share price on the KRX KOSPI Market for the one month period before the date of the adoption of the relevant resolution and (3) the weighted average of the daily share price on the KRX KOSPI Market for the one week period before the date of the adoption of the relevant resolution. However, a court may determine the purchase price if we or dissenting shareholders do not accept the purchase price.

Alternatively, we may inform the shareholders of the annual report and audit report by email or uploading them to our website one week before the general meeting of shareholders. Furthermore, at least one week before the annual general meeting of shareholders, we must make our business reports and audited

non-consolidated

Exchange Controls

Korean Foreign Exchange Controls and Securities Regulations

General

The Foreign Exchange Transaction Act and the Presidential Decree and regulations under that Act and Decree, collectively referred to as the Foreign Exchange Transaction Laws, regulate investment in Korean securities by

non-residents
and issuance of securities outside Korea by Korean companies.
Non-residents
may invest in Korean securities pursuant to the Foreign Exchange Transaction Laws. The FSC has also adopted, pursuant to its authority under the FSCMA, regulations that restrict investment by foreigners in Korean securities and regulate issuance of securities outside Korea by Korean companies.

Subject to certain limitations, the MOEF has authority to take the following actions under the Foreign Exchange Transaction Laws:

if the Government deems it necessary on account of war, armed conflict, natural disaster or grave and sudden and significant changes in domestic or foreign economic circumstances or similar events or circumstances, the MOEF may temporarily suspend performance under any or all foreign exchange transactions, in whole or in part, to which the Foreign Exchange Transaction Laws apply (including suspension of payment and receipt of foreign exchange), impose an obligation to deposit, safe-keep or sell any means of payment to The Bank of Korea, a foreign exchange stabilization fund, certain other governmental agencies or financial companies or impose an obligation on a resident that holds a claim against a non-resident to collect such claim to enable the recovery of the relevant debt back to Korea; and

if the Government deems it necessary on account of war, armed conflict, natural disaster or grave and sudden and significant changes in domestic or foreign economic circumstances or similar events or circumstances, the MOEF may temporarily suspend performance under any or all foreign exchange transactions, in whole or in part, to which the Foreign Exchange Transaction Laws apply (including suspension of payment and receipt of foreign exchange), impose an obligation to deposit, safe-keep or sell any means of payment to The Bank of Korea, a foreign exchange stabilization fund, certain other governmental agencies or financial companies or impose an obligation on a resident that holds a claim against a
non-resident
to collect such claim to enable the recovery of the relevant debt back to Korea; and

if the Government concludes that the international balance of payments and international financial markets are experiencing or are likely to experience significant disruption or that the movement of capital between Korea and other countries are likely to adversely affect the Won, exchange rate or other macroeconomic policies, the MOEF may take action to require any person who intends to effect or effects a capital transaction to deposit all or a portion of the means of payment acquired in such transactions with The Bank of Korea, a foreign exchange stabilization fund, certain other governmental agencies or financial companies.

Under the regulations of the FSC amended on February 4, 2009, (1) if a company listed on the KRX KOSPI Market or a company listed on the KRX KOSDAQ Market has submitted a public disclosure of material matters to

87

Table of Contents
a foreign financial investment supervisory authority pursuant to the laws of the foreign jurisdiction, then it must submit a copy of the public disclosure and a Korean translation thereof to the FSC and the Korea Exchange, and (2) if a KRX KOSPI Market-listed company or KRX KOSDAQ Market-listed company is approved for listing on a foreign stock market or determined to be
de-listed
from the foreign stock market or actually listed on, or
de-listed
from a foreign stock market, then it must submit a copy of any document, which it submitted to or received from the relevant foreign government, foreign financial investment supervisory authority or the foreign stock market, and a Korean translation thereof to the FSC and the Korea Exchange.

Government Review of Issuances of ADSs

In order for us to issue ADSs in excess of US$3050 million, we are required to submit a report to the MOEF with respect to the issuance of the ADSs prior to and after such issuance; provided that such US$3050 million threshold amount would be reduced by the aggregate principal amount of any foreign currency loans borrowed, and any securities offered and issued, outside Korea during the

one-year
period immediately preceding the report’s submission date.date; provided further that when calculating this principal amount, any borrowing of funds or issuance of securities for the purpose of overseas usage shall be excluded. The MOEF may at its discretion direct us to take necessary measures to avoid exchange rate fluctuation in connection with its acceptance of report of the issuance of the ADSs.

Under current Korean laws and regulations, the depositary is required to obtain our prior consent for any proposed deposit of common shares if the number of shares to be deposited in such proposed deposit exceeds the number of common shares initially deposited by us for the issuance of ADSs (including deposits in connection with the initial and all subsequent issuances of ADSs by us or with our consent and stock dividends or other distributions related to the ADSs).

96


deposit exceeds the number of common shares initially deposited by us for the issuance of ADSs (including deposits in connection with the initial and all subsequent issuances of ADSs by us or with our consent and stock dividends or other distributions related to the ADSs).

In addition to such restrictions under Korean laws and regulations, there are also restrictions on the deposits of our common shares for issuance of ADSs. Therefore, a holder of ADRs who surrenders ADRs and withdraws shares may not be permitted subsequently to deposit those shares and obtain ADRs.

We submitted a report to and obtained acceptance thereof by the MOEF for the issuance of ADSs up to an amount corresponding to 24,321,893 common shares. No additional Korean governmental approval is necessary for the issuance of ADSs except that if the total number of our common shares on deposit for conversion into ADSs exceeds 24,321,893 common shares, we may be required to file a report to and obtain acceptance thereof by the MOEF with respect to the increase of such limit and the issuance of additional ADSs.

Reporting Requirements for Holders of Substantial Interests

Under the FSCMA, any person whose direct or beneficial ownership of shares with voting rights, certificates representing the rights to subscribe for shares and equity-related debt securities including convertible bonds and bonds with warrants (collectively referred to as “equity securities”), together with the equity securities beneficially owned by certain related persons or by any person acting in concert with the person, accounts for 5.0% or more of the total outstanding equity securities is required to report the status and purpose (in terms of whether the purpose of shareholding is to affect control over management of the issuer) of the holdings to the FSC and the Korea Exchange within five business days after reaching the 5.0% ownership interest threshold and promptly deliver a copy of such report to the issuer. In addition, any change (1) in the ownership interest subsequent to the report which equals or exceeds 1.0% of the total outstanding equity securities, or (2) in the shareholding purpose is required to be reported to the FSC and the Korea Exchange within five business days from the date of the change. However, the reporting deadline of such reporting requirement is extended for (1) certain professional investors, as specified under the FSCMA, or (2) persons who hold shares for purposes other than management control by up to the tenth day of the month immediately following the last month of the quarter in which the share acquisition or change in their shareholding occurred. Those who reported the purpose of shareholding is to affect control over management of the issuer are prohibited from exercising their voting rights and acquiring additional shares for five days subsequent to the report under the FSCMA.

Violation of these reporting requirements may subject a person to criminal sanctions such as fines or imprisonment and may result in a loss of voting rights with respect to the ownership of unreported equity securities exceeding 5.0%. Furthermore, the FSC may issue an order to dispose of such

non-reported
equity securities.
88

Table of Contents

In addition to the reporting requirements described above, any person whose direct or beneficial ownership of our common shares accounts for 10.0% or more of the total issued and outstanding shares with voting rights (a “major shareholder”) must report the status of his or her shareholding to the Securities and Futures Commission and the Korea Exchange within five business days after he or she becomes a major shareholder. In addition, any change in the ownership interest subsequent to the report must be reported to the Securities and Futures Commission and the Korea Exchange by the fifth business day of any changes in his or her shareholding. Violations of these reporting requirements may subject a person to criminal sanctions, such as fines or imprisonment.

Furthermore, a major shareholder must report his or her trading plan to the Securities and Futures Commission and the Korea Exchange at least between 30 to 90 days prior to the trading, with the specific timeframe to be determined by the Enforcement Decree of the FSCMA, which is yet to be formally promulgated. According to the related legislative notice, this timeframe is set to be 30 days. The enforcement of such reporting obligations is scheduled to take effect on July 24, 2024.

Restrictions Applicable to ADSs

No Korean governmental approval is necessary for the sale and purchase of ADSs in the secondary market outside Korea or for the withdrawal of shares underlying ADSs and the delivery of shares in Korea in connection with the withdrawal, provided that a foreigner who intends to acquire the shares must obtain an investment registration card from the Financial Supervisory Service of Korea (the “FSS”), as described below. The acquisition of the shares by a foreigner must be reported by the foreigner or his or her standing proxy in Korea immediately to the Governor of the FSS (the “Governor”).

Persons who have acquired shares as a result of the withdrawal of shares underlying the ADSs may exercise their preemptive rights for new shares, participate in free distributions and receive dividends on shares without any further governmental approval.

In addition, we are required to file a securities registration statement with the FSC and such securities registration statement has to become effective pursuant to the FSCMA in order for us to issue shares represented by ADSs, except in certain limited circumstances.

Restrictions Applicable to Shares

Odd-lot
trading of shares outside the KRX KOSPI Market or the KRX KOSDAQ Market must involve a financial investment company with a dealing license in Korea as the other party. Foreign investors are prohibited from engaging in margin transactions through borrowing shares from financial investment companies with respect to shares which are subject to a foreign ownership limit.

The Investment Rules requirepreviously required a foreign investor who wisheswished to invest in shares for the first time on the KRX KOSPI Market or the KRX KOSDAQ Market (including converted shares) and shares being publicly offered for initial listing on the KRX KOSPI Market or the KRX KOSDAQ Market to register its identity with the FSS prior to making any such investment; however, the registration requirement does not apply to foreign investors who acquire converted shares with the intention of selling such converted shares within three months from the date of acquisition of the converted shares or who acquire the shares in an

over-the-counter

Upon registration, the FSS will issueissued an investment registration certificate (the “IRC”), also referred to as a “foreign investment ID,” to the foreign investor, an investment registration card which must be presented each timeand the foreign investor openswas required to present the IRC each time he or she opened a brokerage account with a financial investment company or financial institution in Korea. Foreigners eligible to obtain an investment registration card includeIRCs included foreign nationals who havehad not been residing in Korea for a consecutive period of six months or longer, foreign governments, foreign municipal authorities, foreign public institutions, international financial institutions or similar international organizations, corporations incorporated under foreign laws and any person in any additional category designated by decree promulgated under the FSCMA. All Korean offices of a foreign corporation as a group arewere treated as a separate foreigner from the offices of the corporation outside Korea for the purpose of investment registration.

However, the IRC requirement was abolished on June 13, 2023. Recent amendments to the Investment Rules now permit a foreign corporation or depositary issuing depositary receipts may obtain one or more investment registration cards in its name in certain circumstances as described in the relevant regulations.

In the event a foreign investor desires to acquire or sell shares outside the KRX KOSPI Market or the KRX KOSDAQ Market and the circumstances in connection with such sale or acquisition do not fall within the exceptions made for certain limited circumstances described above, then the foreign investor must obtain the prior approval of the Governor. In addition, in the event a foreign investor acquires or sells shares outside the KRX KOSPI Market or the KRX KOSDAQ Market, a prior report to the Bank of Korea may also be required in certain circumstances. A foreign investor must appoint one or more standing proxies among the Korea Securities Depository, foreign exchange banks (including domestic branches of foreign banks), financial investment companies with a dealing, brokerage or collective investment license and certain eligible foreign custodians which will act as a standing proxy to exercise shareholders’ rights, or perform any matters related to the foregoing activities if the foreign investor does not perform these activities himself. Generally, a foreign investor may not permit any person, other than his, her or its standing proxy, to exercise rights relating to its shares or perform any tasks related thereto on his, her or its behalf. However, a foreign investor may be exempted from complying with these standing proxy rules with the approval of the Governor in cases deemed inevitable by reason of conflict between laws of Korea and the home country of the foreign investor.

Under the Investment Rules, with certain exceptions, foreign investors may acquire shares of a Korean company without being subject to any foreign investment ceiling. As onetwo such exception,exceptions, designated public corporations are subject to (i) a 40.0% ceiling on the acquisition of shares by foreigners in the aggregate. Designated public corporations mayaggregate and (ii) unless the corporations’ articles of incorporation set a lower threshold, a 3.0% ceiling on the acquisition of shares by a single person within 3.0% of the total number of shares in their articles of incorporation.foreign individual or entity. Currently, Korea Electric Power Corporation is the only designated public corporation, whichbut it has not set such a ceiling.lower threshold for ownership by a single foreign individual or entity. Furthermore, an investment by a foreign investor of not less than 10.0% of the outstanding shares with voting rights of a Korean company is defined as a direct foreign investment under the Foreign Investment Promotion Law, which is, in general, subject to the report to, and acceptance by, the Ministry of Trade, Industry and Energy of Korea, which delegates its authority to foreign exchange banks or the Korea Trade-Investment Promotion Agency under the relevant regulations. The acquisition of our shares by a foreign investor is also subject to the restrictions prescribed in the Telecommunications Business Act. The Telecommunications Business Act generally limits the maximum aggregate foreign shareholdings in us to 49.0% of the outstanding shares. A foreigner who has acquired shares in excess of such restriction described above may not exercise the voting rights with respect to the shares exceeding such limitations and may be subject to corrective orders.

Under the Foreign Exchange Transaction Laws, a foreign investor who intends to make a portfolio investment in shares of a Korean company listed on the KRX KOSPI Market or the KRX KOSDAQ Market must designate a foreign exchange bank at which he, she or it must open a foreign currency account and a Won account exclusively for stock investments. No approval is required for remittance into Korea and deposit of foreign currency funds in the foreign currency account. Foreign currency funds may be transferred from the foreign currency account at the time required to place a deposit for, or settle the purchase price of, a stock purchase transaction to a Won account opened at a securities company. Funds in the foreign currency account may be remitted abroad without any governmental approval.

Dividends on shares are paid in Won. No governmental approval is required for foreign investors to receive dividends on, or the Won proceeds of the sale of, any such shares to be paid, received and retained in Korea. Dividends paid on, and the Won proceeds of the sale of, any such shares held by a

non-resident
of Korea must be deposited either in a Won account with the investor’s financial investment companies with a securities dealing, brokerage or collective investment license or the investor’s Won account. Funds in the investor’s Won account may be transferred to such investor’s foreign currency account or withdrawn for local living expenses, provided that any withdrawal of local living expenses in excess of a certain amount is reported to the tax authorities by the foreign exchange bank at which the Won account is maintained. Funds in the investor’s Won account may also be used for future investment in shares or for payment of the subscription price of new shares obtained through the exercise of preemptive rights.

Financial investment companies with a securities dealing, brokerage or collective investment license are allowed to open foreign currency accounts with foreign exchange banks exclusively for accommodating foreign investors’ stock investments in Korea. Through these accounts, these financial investment companies may enter into foreign exchange transactions on a limited basis, such as conversion of foreign currency funds and Won funds, either as a counterparty to or on behalf of foreign investors, without the investors having to open their own accounts with foreign exchange banks.

Taxation

United States Taxation

This summary describes certain U.S. federal income tax consequences for a U.S. holder (as defined below) of acquiring, owning, and disposing of common shares or ADSs. This summary applies to you only if you hold our common shares or ADSs as capital assets for tax purposes. This summary does not apply to you if you are a member of a class of holders subject to special rules, such as:

a dealer in securities or currencies;

a trader in securities that elects to use a mark-to-market method of accounting for securities holdings;

a person that holds common shares or ADSs that are a hedge or that are hedged against interest rate or currency risks;

a person that holds common shares or ADSs as part of a straddle or conversion transaction for tax purposes;

a person whose functional currency for tax purposes is not the U.S. dollar;

a person that owns or is deemed to own 10.0% or more of any class of our stock (by vote or value); or

an entity or arrangement that is treated as a partnership for U.S. federal income tax purposes (or partners therein).

This summary is based on the Internal Revenue Code of 1986, as amended, its legislative history, existing and proposed regulations promulgated thereunder, and published rulings and court decisions, all as currently in effect. These laws are subject to change, possibly on a retroactive basis.

Please consult your own tax advisers concerning the U.S. federal, state, local, and other tax consequences of purchasing, owning, and disposing of common shares or ADSs in your particular circumstances.

For purposes of this summary, you are a “U.S. holder” if you are the beneficial owner of a common share or an ADS and are:

a citizen or resident of the United States;

a U.S. domestic corporation; or

otherwise subject to U.S. federal income tax on a net income basis with respect to income from the common share or ADS.

In general, if you are the beneficial owner of ADSs, you will be treated as the beneficial owner of the common shares represented by those ADSs for U.S. federal income tax purposes, and no gain or loss will be recognized if you exchange an ADS for the common share represented by that ADS.

Dividends

The gross amount of cash dividends that you receive (prior to deduction of Korean taxes) generally will be subject to U.S. federal income taxation as foreign source “passive income” dividend income and will not be eligible for the dividends received deduction. Dividends paid in Won will be included in your income in a U.S. dollar amount calculated by reference to the exchange rate in effect on the date of your receipt of the dividend, in the case of common shares, or the depositary’s receipt, in the case of ADSs, regardless of whether

101


the payment is in fact converted into U.S. dollars. If such a dividend is converted into U.S. dollars on the date of receipt, you generally should not be required to recognize foreign currency gain or loss in respect of the dividend income.

Subject to certain exceptions for short-term and hedged positions, the U.S. dollar amount of dividends received by an individual with respect to the ADSs will be subject to taxation at a preferential rate if the dividends are “qualified dividends.” Dividends paid on the ADSs will be treated as qualified dividends if (1) the ADSs are readily tradable on an established securities market in the United States and (2) we were not, in the year prior to the year in which the dividend was paid, and are not, in the year in which the dividend is paid, a passive foreign investment company as defined for U.S. federal income tax purposes (“PFIC”),PFIC, as discussed below under “

Passive Foreign Investment Company Rules.” The ADSs are listed on the NYSE, and will qualify as readily tradable on an established securities market in the United States so long as they are so listed. As described below under “Passive Foreign Investment Company Rules”,Rules,” we do not believe that we may bewere classified as a PFIC with respect to our taxable yearyears ending December 31, 2021 but2022 and 2023. We do not expect to be classified as a PFIC for the current taxable year or in the
92

Table of Contents
reasonably foreseeable future based on the present composition of our income and assets and our expectations regarding our income and assets in the future.Accordingly, U.S. holders of commons shares or ADSs should consult their own tax advisors regarding the availability of the reduced dividend tax rate for dividends with respect to our common shares or ADSs.

Distributions of additional shares in respect of common shares or ADSs that are made as part of a

pro-rata
distribution to all of our stockholders generally will not be subject to U.S. federal income tax.

Sale or Other Disposition

Subject to the discussion below under “Passive Foreign Investment Company Rules,” for U.S. federal income tax purposes, gain or loss you realize on a sale or other disposition of common shares or ADSs generally will be treated as U.S. source capital gain or loss, and will be long-term capital gain or loss if the common shares or ADSs were held for more than one year. Your ability to offset capital losses against ordinary income is limited. Long-term capital gain recognized by an individual U.S. holder generally is subject to taxation at reduced rates.

Passive Foreign Investment Company Rules

Special U.S. tax rules apply to companies that are considered to be PFICs. We will be classified as a PFIC in a particular taxable year if either (i) 75 percent or more of our gross income for the taxable year is passive income; or (ii) 50%50 percent or more of the value of our assets (generally determined on the basis of a quarterly average) is attributable to assets that produce or are held for the production of passive income. Investments in companies in which we own less than 25 percent of the stock (by value) are considered to be assets that produce passive income.

The determination whether we are a PFIC is made annually based on the particular facts and circumstances, such as the composition of our income and the valuation of our assets. Due to fluctuations in our stock price and changes in the value and composition of our assets, including our substantial investment in the stock of SK Hynix prior to the

Spin-off,
which was treated as a passive asset for this purpose, weWe do not believe that we may bewere classified as a PFIC for U.S. federal income tax purposes forwith respect to our taxable yearyears ending December 31, 2021.2022 and 2023. We do not expect to be classified as a PFIC for the current taxable year or in the reasonably foreseeable future, based on the present composition of our income and assets and our expectations regarding our income and assets in the future. Stock market volatility could exacerbate these considerations. See “Item 3.D. Risk Factors — Risks Relating to Our BusinessKorea — The ongoing global pandemic of a new strain of coronavirus
(“COVID-19”)
Unfavorable financial and any possible recurrence of other types of widespread infectious diseaseseconomic developments in Korea may adversely affect our business, financial condition and results of operations.have an adverse effect on us.

You should consult your own tax advisors regarding our classification as a PFIC for 20212022, 2023 or in the current or future years.

If we are classified as a PFIC, and you do not make a

mark-to-market
election, as described in the following paragraph, you will be subject to a special tax at ordinary income tax rates on “excess distributions” (generally, any distributions that you receive in a taxable year that are greater than 125 percent of the average annual

102


distributions that you have received in the preceding three taxable years, or your holding period, if shorter), including gain that you recognize on the sale of your common shares or ADSs. The amount of income tax on any excess distributions will be increased by an interest charge to compensate for tax deferral, calculated as if the excess distributions were earned ratably over the period you hold your common shares or ADSs. Classification as a PFIC may also have other adverse tax consequences, including, in the case of individuals, the denial of a

step-up
in the basis of your common shares or ADSs at death.

Although the determination of whether we are a PFIC is made annually, if we are a PFIC for any taxable year during which a U.S. holder holds our common shares or ADSs, such U.S. holder will generally be subject to the unfavorable rules described above for that year and for each subsequent year in which such U.S. holder holds the common shares or ADSs (even if we do not qualify as a PFIC in such subsequent years). However, if we cease to be a PFIC, a U.S. holder can avoid the continuing impact of the PFIC rules by making a special election to recognize gain as if such U.S. holder’s common shares or ADSs had been sold on the last day of the last taxable year during which we were a PFIC. U.S. holders should consult their own tax advisor about the advisability of making this election.

93

Table of Contents

A U.S. holder may be able to avoid the unfavorable rules described above by electing to mark its ADSs to market, provided the ADSs are treated as “marketable stock.” The ADSs generally will be treated as marketable stock if the ADSs are “regularly traded” on a “qualified exchange or other market” (which includes the NYSE). Further, it should also be noted that only the ADSs and not the common shares are listed on the NYSE. Consequently, a U.S. holder that holds common shares that are not represented by ADSs may not be eligible to make a

mark-to-market
election in respect of those common shares. If the U.S. holder makes a
mark-to-market
election, the U.S. holder will be required in any year in which we are a PFIC to include as ordinary income the excess of the fair market value of its ADSs at
year-end
over the U.S. holder’s basis in those ADSs. If at the end of the U.S. holder’s taxable year, the U.S. holder’s basis in the common shares or ADSs exceeds their fair market value, the U.S. holder will be entitled to deduct the excess as an ordinary loss, but only to the extent of the U.S. holder’s net
mark-to-market
gains from previous years. A U.S. holder’s adjusted tax basis in the ADSs will be increased by the amount of any income inclusion and decreased by the amount of any deductions under the
mark-to-market
rules. In addition, any gain the U.S. holder recognizes upon the sale of the U.S. holder’s ADSs in a year in which we are a PFIC will be taxed as ordinary income in the year of sale and any loss will be treated as an ordinary loss to the extent of the U.S. holder’s net
mark-to-market
gains from previous years. If a U.S. holder makes a
mark-to-market
election, it will be effective for the taxable year for which the election is made and all subsequent taxable years unless the ADSs are no longer regularly traded on a “qualified exchange or other market” or the Internal Revenue Service (“IRS”) consents to the revocation of the election. If a U.S. holder makes a
mark-to-market
election in respect of a corporation classified as a PFIC and such corporation ceases to be classified as a PFIC, the U.S. holder will not be required to take into account the
mark-to-market
gain or loss described above during any period that such corporation is not classified as a PFIC. Because a
mark-to-market
election generally cannot be made for any lower-tier PFICs that we may own (unless shares of such lower-tier PFIC are themselves “marketable”), a U.S. holder who makes a
mark-to-market
election with respect to our common shares may continue to be subject to the general PFIC rules with respect to such U.S. holder’s indirect interest in any of our
non-United
States subsidiaries that is classified as a PFIC. U.S. holders are urged to consult their own tax advisors about the availability of the
mark-to-market
election, the consequences of not making a
mark-to-market
election for the first year during which a U.S. holder holds interests in our common shares or ADSs and we are a PFIC, and whether making the election would be advisable in their particular circumstances.

Although a U.S. holder can also avoid the unfavorable PFIC rules described above by electing to treat its common shares or ADSs as interests in a qualified electing fund (“QEF”), we do not intend to provide the information that would allow a U.S. holder to make such an election. Accordingly, in the event that we are treated as a PFIC, a U.S. holder will not be able to make a “QEF election.”

A U.S. holder that owns an equity interest in a PFIC must annually file IRS Form 8621, and may be required to file other IRS forms. A failure to file one or more of these forms as required may toll the running of the statute of limitations in respect of each of the U.S. holder’s taxable years for which such form is required to be filed. As

103


a result, the taxable years with respect to which the U.S. holder fails to file the form may remain open to assessment by the IRS indefinitely, until the form is filed.

The U.S. federal income tax rules relating to PFICs are complex. U.S. holders are strongly urged to consult their own tax advisors regarding our potential classification as a PFIC and regarding the U.S. federal income tax consequences of acquiring, holding and disposing of our common shares or ADSs if we are so classified, including the advisability of making a

mark-to-market
election, if available.

Foreign Tax Credit Considerations

You should consult your own tax advisers to determine whether you are subject to any special rules that limit your ability to make effective use of foreign tax credits, including the possible adverse impact of failing to take advantage of benefits under the income tax treaty between the United States and Korea. If no such rules apply, youKorea (the “Treaty”).

Subject to generally applicable limitations and conditions, Korean withholding tax imposed on dividends paid at the appropriate rate applicable to a U.S. holder may claimbe eligible for a credit against yoursuch U.S. holder’s U.S. federal income tax liability. These generally applicable limitations and conditions include requirements adopted by the IRS in regulations promulgated in December 2021 and any Korean tax will need to satisfy these requirements in order to be eligible to be a creditable tax for a U.S. holder. In the case of a U.S. holder that consistently elects to apply a modified version of these rules under recently issued temporary guidance, and complies with specific requirements set forth in such guidance, the Korean tax on dividends will be treated as meeting the new requirements and therefore as a creditable tax. In the case of all other U.S. holders, the application of these requirements to the Korean tax on dividends is uncertain and we have not determined whether these requirements are met. If the Korean tax is not a creditable tax for a U.S. holder or the U.S. holder does not elect to claim a foreign tax credit for any foreign income taxes paid or accrued in the same taxable year, the U.S. holder may be able to deduct the Korean tax in computing such U.S. holder’s taxable income for U.S. federal income tax purposes. Dividends will constitute income from sources without the United States and, if such withholding tax is a creditable tax for a U.S. holder that elects to claim foreign tax credits, generally will constitute “passive category income” for foreign tax credit purposes.

Gain, if any, realized by a U.S. holder on the sale or other disposition of the common shares or ADSs generally will be treated as U.S. source income for U.S. foreign tax credit purposes. A U.S. holder that is eligible for, and properly elects, the benefits of the Treaty, will generally not be subject to Korean withholding tax on capital gains. If a U.S. holder is not eligible for benefits under the Treaty and is therefore subject to Korean withholding tax on capital gains, the U.S. holder generally will not be entitled to credit any Korean tax imposed on the sale or other disposition of the shares against such U.S. holder’s U.S. federal income tax liability, for Korean taxes withheld from dividends onexcept in the common shares or ADSs, so longcase of a U.S. holder that consistently elects to apply a modified version of the U.S. foreign tax credit rules that is permitted under recently issued temporary guidance and complies with the specific requirements set forth in such guidance. Consequently, even if the withholding tax qualifies as you have owned our common shares or ADSs (anda creditable tax, a U.S. holder may not entered into specified kinds of hedging transactions) for at least a

16-day
period that includesbe able to credit the
ex-dividend
date. Instead of claiming a tax against its U.S. federal income tax liability unless such credit you may, if you so elect, deduct such Korean taxes in computing your taxable income, subjectcan be applied (subject to generally applicable limitations underconditions and limitations) against tax due on other income treated as derived from foreign sources. If the Korean tax is not a creditable tax, the tax would reduce the amount realized on the sale or other disposition of the shares even if the U.S. holder has elected to claim a foreign tax law.

the Treasury and the IRS are considering proposing amendments to the December 2021 regulations and that the temporary guidance can be relied upon until additional guidance is issued that withdraws or modifies the temporary guidance.

Specified Foreign Financial Assets

Certain U.S. holders that own “specified foreign financial assets” with an aggregate value in excess of U.S.$50,000 on the last day of the taxable year or U.S.$75,000 at any time during the taxable year are generally required to file an information statement along with their tax returns, currently on IRS Form 8938, with respect to such assets. “Specified foreign financial assets” include any financial accounts held at a

non-U.S.
financial institution, as well as securities issued by a
non-U.S.
issuer (which would include the common shares or ADSs) that are not held in accounts maintained by financial institutions. Higher reporting thresholds apply to certain individuals living abroad and to certain married individuals. Regulations extend this reporting requirement to certain entities that are treated as formed or availed of to hold direct or indirect interests in specified foreign financial assets based on certain objective criteria. U.S. holders who fail to report the required information could be subject to substantial penalties. Prospective investors should consult their own tax advisers concerning the application of these rules to their investment in the common shares or ADSs, including the application of the rules to their particular circumstances.

U.S. Information Reporting and Backup Withholding Rules

Payments of dividends and sales proceeds that are made within the United States or through certain

U.S.-related
financial intermediaries are subject to information reporting and may be subject to backup withholding unless the holder (1) is a corporation or other exempt recipient and demonstrates this when required or (2) provides a taxpayer identification number and certifies that no loss of exemption from backup withholding has occurred. Holders that are not U.S. personsa “United States Person” (as defined in the Code) generally are not subject to information reporting or backup withholding. However, such a holder may be required to provide a certification of its
non-U.S. status
in connection with payments received within the United States or through a U.S.-related financial intermediary.

Korean Taxation

The following is a summary of the principal Korean tax consequences to owners of the common shares or ADSs, as the case may be, who are

non-resident
individuals or
non-Korean
corporations without a permanent establishment in Korea to which the relevant income is attributable or with which the relevant income is effectively connected
(“Non-resident
Holders”). The statements regarding Korean tax laws set forth below are based on the laws in force and as interpreted by the Korean taxation authorities as of the date hereof. This summary is not exhaustive of all possible tax considerations which may apply to a particular investor and potential investors are advised to satisfy themselves as to the overall tax consequences of the acquisition, ownership and disposition of the common shares or ADSs, including specifically the tax consequences under Korean law, the laws of the jurisdiction of which they are resident, and any tax treaty between Korea and their country of residence, by consulting their own tax advisors.

Tax on Dividends

Dividends on the common shares or ADSs paid (whether in cash or in shares) to a

Non-resident
Holder will be subject to Korean withholding taxes at the rate of 22.0% (including local income tax) or such lower rate as is applicable under a treaty between Korea and such
Non-resident
Holder’s country of tax residence. Free distributions of shares representing a capitalization of certain capital surplus reserves may be subject to Korean withholding taxes.
95

Table of Contents

The tax is withheld by the payer of the dividend. While it is the payer that is required to withhold the tax, Korean law generally entitles the person who was subject to the withholding of Korean tax to recover from the Government any part of the Korean tax withheld upon providing evidence that it was entitled to have tax withheld at a lower rate if certain conditions are met.

105


Tax on Capital Gains

As a general rule, capital gains earned by

Non-resident
Holders upon transfer of the common shares or ADSs are subject to Korean withholding tax at the lower of (1) 11.0% (including local income tax) of the gross proceeds realized or (2) 22.0% (including local income tax) of the net realized gains (subject to the production of satisfactory evidence of the acquisition costs and certain direct transaction costs), unless exempt from Korean income taxation under the effective Korean tax treaty with the
Non-resident
Holder’s country of tax residence.

However, a

Non-resident
Holder will not be subject to Korean income taxation on capital gains realized upon the sale of the common shares through the KRX KOSPI Market if the
Non-resident
Holder (1) has no permanent establishment in Korea and (2) did not or has not owned (together with any shares owned by any entity with certain special relationship with such
Non-resident
Holder) 25.0% or more of the total issued and outstanding shares of us at any time during the calendar year in which the sale occurs and during the five calendar years prior to the calendar year in which the sale occurs.

It should be noted that capital gains earned by you (regardless of whether you have a permanent establishment in Korea) from a transfer of ADSs outside Korea will generally be exempt from Korean income taxation, provided that the ADSs are deemed to have been issued overseas. If and when an owner of the underlying common shares transfers the ADSs following the conversion of the underlying shares for ADSs, such person will not be exempt from Korean income taxation.

Inheritance Tax and Gift Tax

Korean inheritance tax is imposed upon (1) all assets (wherever located) of the deceased if at the time of his death he was a tax resident of Korea and (2) all property located in Korea which passes on death (irrespective of the domicile of the deceased). Gift tax is imposed in similar circumstances to the above. The taxes are imposed if the value of the relevant property is above a certain limit and vary depending on the value of the property and the identity of the parties involved.

Under Korean inheritance and gift tax laws, securities issued by a Korean corporation are deemed to be located in Korea irrespective of where they are physically located or by whom they are owned.

Securities Transaction Tax

Securities transaction tax is imposed on the transfer of shares issued by a Korean corporation or the right to subscribe for such shares generally at the rate of 0.43%0.35% of the sales price. In the case of the transfer of shares listed on the KRX KOSPI Market (such as our common shares), the securities transaction tax is imposed generally at the rate of (1) 0.23%0.18% of the sales price of such shares (including agricultural and fishery special surtax thereon) if traded on the KRX KOSPI Market or (2) subject to certain exceptions, 0.43%0.35% of the sales price of such shares if traded outside the KRX KOSPI Market.

Securities transaction tax or the agricultural and fishery special surtax is not applicable if (1) the shares or rights to subscribe for shares are listed on a designated foreign stock exchange and (2) the sale of the shares takes place on such exchange.

Securities transaction tax, if applicable, must be paid by the transferor of the shares or rights, in principle. When the transfer is effected through a securities settlement company, such settlement company is generally required to withhold and pay (to the tax authority) the tax, and when such transfer is made through a financial investment company with a brokerage license only, such company is required to withhold and pay the tax. Where the transfer is effected by a

Non-resident
Holder without a permanent establishment in Korea, other than through a securities settlement company or a financial investment company with a brokerage license, the transferee is required to withhold the securities transaction tax. Failure to do so will result in the imposition of penalties equal to the sum
96

Table of Contents
of (1) between 10.0% to 40.0% of the tax amount due, depending on the nature of the improper reporting, and (2) 8.03% per annum on the tax amount due for the default period.

106


Tax Treaties

Currently, Korea has income tax treaties with a number of countries, inter alia, Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Italy, Japan, Luxembourg, Ireland, the Netherlands, New Zealand, Norway, Singapore, Sweden, Switzerland, the United Kingdom and the United States under which the rate of withholding tax on dividend and interest is reduced, generally to between 5.0% and 16.5% (including local income tax), and the tax on capital gains derived by a

non-resident
from the transfer of securities issued by a Korean company is often eliminated.

Each

Non-resident
Holder of common shares should inquire for itself whether it is entitled to the benefits of a tax treaty with Korea. It is the responsibility of the party claiming the benefits of a tax treaty in respect of interest, dividend, capital gains or “other income” to submit to us (or our agent), the purchaser or the financial investment company with a brokerage license, as the case may be, prior to or at the time of payment, such evidence of tax residence of the party claiming the treaty benefit as the Korean tax authorities may require in support of its claim for treaty protection. In the absence of sufficient proof, we (or our agent), the purchaser or the financial investment company with a brokerage license, as the case may be, must withhold tax at the normal rates.

Furthermore, in order for a

non-resident
of Korea to obtain the benefits of tax exemption on certain Korean source income (e.g., capital gains and interest) under an applicable tax treaty, Korean tax law requires such
non-resident
(or (or its agent) to submit to the payer of such Korean source income an application for a tax exemption along with a certificate of tax residency of such
non-resident
issued by a competent authority of the
non-resident’s
country of tax residence, subject to certain exceptions. The payer of such Korean source income, in turn, is required to submit such application to the relevant district tax office by the ninth day of the month following the date of the first payment of such income.

For a

non-resident
of Korea to obtain the benefits of treaty-reduced tax rates on certain Korean source income (e.g., capital gains and interest) under an applicable tax treaty, Korean tax law requires such
non-resident
(or (or its agents) to submit to the payer of such Korean source income an application for treaty-reduced tax rates prior to receipt of such Korean source income; provided, however, that an owner of ADSs who is a
non-resident
of Korea is not required to submit such application, if the Korean source income on the ADSs is paid through an account opened at the Korea Securities Depository by a foreign depository.

At present, Korea has not entered into any tax treaty relating to inheritance or gift tax.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to foreign exchange rate and interest rate risk primarily associated with underlying liabilities and to equity price risk as a result of our investment in equity instruments.

We have entered into a

floating-to-fixed
cross currency interest rate swap contract to hedge foreign currency and interest rate risks with respect to US$300 million of bonds issued in March 2020. In addition, we have entered into
fixed-to-fixed
cross currency swap contracts to hedge the foreign currency risks of US$400 million of bonds issued in July 2007 US$5.7 million of borrowings from December 2013, US$500 million of bonds issued in April 2018 and US$300 million of bonds issued in August 2018. We also entered into
floating-to-fixed
interest rate swap contracts to hedge interest rate risks with respect to Won 12.5 billion of borrowings from December 2017 and Won 25.0 billion of borrowings from December 2018.June 2023. See note 22 of the notes to our consolidated financial statements. We may consider in the future entering into other such transactions solely for hedging purposes.

The following discussion and tables, which constitute “forward looking statements” that involve risks and uncertainties, summarize our market-sensitive financial instruments including fair value, maturity and contract terms. These tables address market risk only and do not present other risks which we face in the normal course of business, including country risk, credit risk and legal risk.

Exchange Rate Risk

Korea is our main market and, therefore, substantially all of our cash flow is denominated in Won. We are exposed to foreign exchange risk related to foreign currency denominated liabilities. These liabilities relate primarily to foreign currency denominated debt, primarily in Dollars. A 10.0% increase in the exchange rate between the Won and all foreign currencies would result in an increase in profit before income tax of Won 2.86.3 billion, with a decrease of 10.0% in the exchange rate having the opposite effect, as of December 31, 2021.2023. For a further discussion of our exchange rate risk exposures, see note 35(1) of the notes to our consolidated financial statements.

Weighted average rates of the portfolio at the period end.

A 1.0% point increase in interest rates would result in a decrease in profit before income tax of Won 20.913.8 billion (consisting of Won 0.9 billion in relation to the floating-rate borrowings for which we have not entered into interest rate swaps and Won 12.9 billion in relation to the floating-rate long-term payables – other that are exposed to interest rate risk) with a 1.0% point decrease in interest rates having the opposite effect, as of December 31, 2021.2023. For a further discussion of our interest rate risk exposures, see note 35(1) of the notes to our consolidated financial statements.

Equity Price Risk

We are also subject to market risk exposure arising from changes in the equity securities market, which affect the fair value of our equity portfolio. As of December 31, 2021, 20202023, 2022 and 2019,2021, a 10.0% increase in the equity indices where our equity investments at fair value through other comprehensive income are listed, with all other variables held constant, would have increased our total equity by Won 140.085.0 billion, Won 94.677.8 billion and Won 40.8103.2 billion, respectively, with a 10.0% decrease in the equity index having the opposite effect.

The foregoing sensitivity analysis assumes that all variables other than changes in the equity index are held constant, and that our equity investments at fair value through other comprehensive income had moved according to the historical correlation to the index, and as such, does not reflect any correlation between the equity index and other variables. For a further discussion of our equity price risk exposures, see note 35(1) of the notes to our consolidated financial statements.

Holders of ADRs must pay (1) taxes and other governmental charges, (2) share transfer registration fees on deposits of shares of common stock, (3) such cable, telex, facsimile transmission and delivery expenses as are expressly provided in the deposit agreement to be at the expense of persons depositing shares of common stock or holders of ADRs and (4) such reasonable expenses as are incurred by the ADR depositary in the conversion of foreign currency into United States dollars.

Notwithstanding any other provision of the deposit agreement, in the event that the ADR depositary determines that any distribution in property (including shares or rights to subscribe therefor or other securities) is subject to any tax or governmental charges which the ADR depositary is obligated to withhold, the ADR depositary may dispose of all or a portion of such property (including shares and rights to subscribe therefor) in such amounts and in such manner as the ADR depositary deems necessary and practicable to pay such taxes or governmental charges, including by public or private sale, and the ADR depositary will distribute the net proceeds of any such sale or the balance of any such property after deduction of such taxes or governmental charges to the holders of ADSs entitled thereto in proportion to the number of ADSs held by them respectively.

All such charges may be changed by agreement between the ADR depositary and us at any time and from time to time, subject to the deposit agreement. The right of the ADR depositary to receive payment of fees, charges and expenses shall survive the termination of this deposit agreement and, as to any depositary, the resignation or removal of such depositary pursuant to the deposit agreement.

Payments made by ADR Depositary

The ADR depositary reimburses us for certain expenses we incur in connection with our ADR program, subject to certain ceilings. These reimbursable expenses currently include expenses relating to the preparation of SEC filings and submissions, listing fees, education and training fees, corporate action expenses and other miscellaneous fees. In the fiscal year 2021,2023, we received US$1,791,012.52,201,641.87, net of taxes, from the ADR depositary in connection with such reimbursements.

CONTROLS AND PROCEDURES

Our management has evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of our disclosure controls and procedures, as such term is defined in

Rules 13a-15(e)
and
15d-15(e)
under the Exchange Act, as of December 31, 2021.2023. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of such date. Our disclosure controls and procedures are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and that it is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in

Rules 13a-15(f)
and
15d-15(f)
under the Exchange Act, as of December 31, 2021.2023. Because of its inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that a misstatement of our consolidated financial statements would be prevented or detected. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control — Integrated Framework (2013 framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with IFRS, as issued by the IASB. Based on our evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2021.

On December 20, 2021, our Audit Committee approved the appointment of Ernst & Young Han Young, or E&Y, as our principal accountant to audit our consolidated financial statements prepared in accordance with IFRS, as issued by the IASB for the fiscal years ending December 31, 2022, 2023 and 2024, and, in effect, dismissed KPMG Samjong, our former independent registered public accountants (including for the fiscal years ending December 31, 2019, 2020 and 2021). We provided notice of the expected dismissal to KPMG Samjong on December 10, 2021. E&Y’s appointment was effective as of January 1, 2022, and KPMG Samjong’s dismissal was effective as of April 28, 2022, the date of completion of its audit of our financial statements for the fiscal year ending December 31, 2021 and the issuance of its report thereon.
The decision of our Audit Committee to dismiss KPMG Samjong, and to appoint E&Y, as our principal accountant to audit our financial statements prepared in accordance with IFRS, as issued by the IASB, was largely driven by the FSC’s designation of E&Y as our external auditor in December 2021 pursuant to the requirement of the amended Act on External Audit of Stock Companies, which became effective in November 2018. The Act on External Audit of Stock Companies, as amended, requires that a publicly listed Korean company that was audited by an external auditor of its choice for six consecutive years change its external auditor to one designated by the FSC for a period of three consecutive years.
KPMG Samjong’s reports on our consolidated financial statements for each of the two most recent fiscal years ended December 31, 2021 and 2020 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principles. During the two most recent fiscal years
103

Table of Contents
ended December 31, 2021 and 2020 and up until April 28, 2022, there were: (i) no disagreements between us and KPMG Samjong on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of KPMG Samjong, would have caused KPMG Samjong to make reference to the subject matter of the disagreements in its reports on our consolidated financial statements; and (ii) no “reportable events” as defined in Item 16F(a)(1)(v) of Form 20-F.
During the two most recent fiscal years ended December 31, 2021 and 2020 and up until April 28, 2022, neither we nor anyone on our behalf consulted E&Y regarding either (i) the application of IFRS, as issued by the IASB to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on our consolidated financial statements (and neither a written report nor oral advice was provided to us that E&Y concluded was an important factor considered by us in reaching a decision as to any accounting, auditing or financial reporting issue under IFRS, as issued by the IASB) or (ii) any matter that was either the subject of a “disagreement” (as defined in Item 16F(a)(1)(iv) of Form
20-F
and the related instructions to Item 16F) or a “reportable event” (as described in Item 16F(a)(1)(v) of Form
20-F)
We provided a copy of the disclosure in this Item 16F to KPMG Samjong and requested that KPMG furnish us with a letter addressed to the Securities and Exchange Commission stating whether it agrees with such disclosure, and if it does not agree, stating the respects in which it does not agree. A copy of KPMG’s letter dated April 28, 2022 is filed as Exhibit 15.1 to this annual report for the fiscal year ended December 31, 2021.

CORPORATE GOVERNANCE

The following is a summary of the significant differences between the NYSE’s corporate governance standards and those that we follow under Korean law.

NYSE Corporate Governance Standards

  

Our Corporate Governance Practice

Director Independence

  
Listed companies must have a majority of independent directors.  Of the eightnine members of our board of directors, five are independent directors.

Executive Session

  
Non-managementdirectors must meet in regularly scheduled executive sessions without management. Independent directors should meet alone in an executive session at least once a year.  Our audit committee, which is comprised solely of four independent directors, holds meetings whenever there are matters related to management directors, and such meetings are generally held once every month.

Nomination/Corporate Governance Committee

  
Listed companies must have a nomination/corporate governance committee composed entirely of independent directors. The committee must have a charter that addresses the purpose, responsibilities (including development of corporate governance guidelines) and annual performance evaluation of the committee.  Although we do not have a separate nomination/corporate governance committee, we maintain an independent director nomination committee composed of twoone non-independent director and three independent directors and one management director.directors.

Compensation Committee

  
Listed companies must have a compensation committee composed entirely of independent directors. The committee must have a charter that addresses the purpose, responsibilities and annual performance evaluation of the committee. The charter must be made available on the company’s website. In addition, in accordance with the SEC rules adopted pursuant to Section 952 of the Dodd-Frank Act, the NYSE listing standards were amended to expand the factors relevant in determining whether a committee member has a relationship with the company.  We maintain a compensation review committee comprised of one
non-independent
director and three independent directors.

Corporate Governance Guidelines

  
Listed companies must adopt and disclose corporate governance guidelines.  We have adopted a Corporate Governance Charter, which is available (in Korean) on our website at www.sktelecom.com.

CYBERSECURITY

Risk Management and Strategy

We maintain a comprehensive process for assessing, identifying and managing material risks from cybersecurity threats as part of our overall risk management system and processes.

We understand the importance of preserving trust and protecting personal and other confidential and sensitive information. Cybersecurity is a critical component of our overall risk management system and we have established an information security and cybersecurity framework to help safeguard the confidentiality, integrity and access of our information assets, and to ensure regulatory, contractual and operational compliance. We utilize policies, software, training programs and hardware solutions to protect and monitor our environment, including multifactor authentication, firewalls, intrusion detection and prevention systems, vulnerability and penetration testing, and identity management systems.

Our information security and cybersecurity framework and infrastructure comply with and incorporate the Information Security Management System (“ISMS”) and Personal Information and Information Security Management System (“ISMS-P”) standards, which significantly overlap with International Organization for Standardizations (“ISO”) standards. Our certifications under such standards are valid for three years, and we are subject to an annual audit to maintain such certifications.

Our Chief Information Security Officer (“CISO”), under the supervision of our board of directors and the ESG Committee, oversees our approach to managing cybersecurity and digital risk and regularly engages with cross-functional teams including legal, human resources, facilities and corporate risk. We also carry insurance that provides protection against potential losses arising from cybersecurity incidents and annually review our policy and levels of coverage based on current risks.

We conduct annual information security awareness training for all directors, officers and employees and enhanced training for specialized personnel, such as personal information handlers, location information handlers and information security managers, and publish periodic cybersecurity newsletters to highlight any emerging or urgent security threats. We also conduct cyber awareness training and run tabletop exercises to simulate responses to cybersecurity incidents, and use the findings to improve our practices, procedures and technologies.

We also engage with a range of external experts, including cybersecurity assessors and consultants, to assess and report on the effectiveness of our cybersecurity and data privacy controls, and our internal incident response preparedness, as well as to help identify areas for continued focus and improvement. In addition, we engage outside legal counsel regarding cybersecurity issues such as regulatory compliance, materiality determinations, disclosure obligations and best practices for oversight, as needed. Since 2006, we have been a member of CONCERT, a Government-sponsored organization which allows members to share best practices, fight cybercrime, enhance privacy, discuss new technologies and better understand the evolving regulatory environment and advance capabilities in these areas.

Our cybersecurity risk management processes extend to the oversight and identification of threats associated with our use of third-party service providers. We review our vendors’ cybersecurity practices before we enter into business transactions with them, and we seek to contractually obligate vendors to operate their environments in accordance with strict cybersecurity standards. We also develop contingency plans for business continuity if our vendors are subject to a cyberattack that impacts our use of their systems. Furthermore, we assess the risks faced by our partners, including branch offices and stores in our extensive distribution network, at least once a year in order to assess risks and identify threats and vulnerabilities, and implement corrective measures. Since 2015, we have been engaging third-party assessors to conduct annual audits of our distribution network and have been conducting remote diagnoses of all personal information-processing personal computers on a weekly basis.

116


105

Our internal audit department conducts annual audits to review and evaluate the effectiveness of our internal controls relating to information security and disclosure obligations.

Our business, financial condition and results of operations have not been materially affected by risks from cybersecurity threats, including as a result of previous cybersecurity incidents, but we cannot provide assurance that they will not be materially affected in the future by such risks and any future material incidents.

Governance

Management

The cybersecurity risk management processes described above are primarily managed by our CISO, who also serves as our Chief Privacy Officer and has been acting in such role since 2019. Our CISO has more than 20 years of experience in the area of information technology and more than six years of experience in the area of information protection. Our CISO maintains the following internationally recognized certificates: ISO27001, ISO27017 and ISO27018. In order to streamline our information protection and privacy governance regime, we operate an integrated control center led by our CISO to prevent common malicious and abusive Internet activities, such as spam, hacking of personal information, distributed denial-of-service attacks and dissemination of viruses, worms and other destructive or disruptive software, and to respond in real time when a situation arises. We also hold an Information Protection Committee meeting every week under the leadership of our CISO. Furthermore, key executive officers such as our Chief Operating Officer and Chief Serious-accident Prevention Officer manage company-wide information security risks under the leadership of our Chief Executive Officer.

Board of Directors

Our board of directors is committed to mitigating data privacy and cybersecurity risks and recognizes the importance of these issues as part of our risk management framework. While the board of directors, with assistance from the ESG Committee, maintains ultimate responsibility for the oversight of our data privacy and cybersecurity program and risks due to the complexities of the risks involved or the importance of cybersecurity-related risks to stakeholders, it has delegated certain responsibilities to our CISO who heads an execution organization composed of executive officers with relevant experience. In addition, our board of directors receives annual review reports covering the status of the company’s management and protection of personal credit information from our CISO. For information security issues that have a company-wide impact, our board of directors convenes a crisis response situation room to directly engage with and advise our CISO, and the CISO reports to the board of directors the results of work performed based on such advice.

Our board of directors’ principal role is one of oversight, recognizing that management is responsible for the design, implementation and maintenance of an effective program for protecting against and mitigating data privacy and cybersecurity risks. Members of the board of directors stay apprised of the rapidly evolving cyber threat landscape and provide guidance to management as appropriate in order to address the effectiveness of our overall data privacy and cybersecurity program.

The spun-off businesses are presented as discontinued operations, and the comparative consolidated statements of income have been re-presented to present the discontinued operations separately from continuing operations.thereon.
Basis for Opinion
These consolidated financial statements are the responsibility of the Group’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Group in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error of fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Impairment assessment of December 31, 2021. The Group performs impairment test for goodwill for the fixed-line telecommunication services cash
generating unit
Description of
the Matter
At December 31, 2023, the amount of goodwill allocated to the fixed-line telecommunication services CGU is
W
764,082 million. As described in notes 3 (10) and 16 of the consolidated financial statements, the Group assesses impairment of goodwill allocated to a cash generating unit (“CGU”), at least, annually or when there is an indication of possible impairment by comparing the carrying amount of the CGU to its recoverable amount and the carrying amount of a CGU to which goodwill is allocated. The recoverable amount of the fixed-line telecommunication services CGU was determined based on its
value-in-use
(“VIU”).
We identified the evaluation of goodwill impairment for the fixed-line telecommunication services CGU as a critical audit matter. Estimation of certain assumptions involves a high degree of subjectivity and uncertainty and therefore, involved a high degree of subjective and complex auditor judgment. Specifically, estimates of operating revenue, perpetual growth rate and discount rate used to estimate the VIU of the fixed-line telecommunication services CGU were challenging to test.
The following are the primary procedures we performed to address this critical audit matter.
We evaluated the design and tested the operating effectiveness of certain internal controls related to the Group’s goodwill impairment analysis. This included controls related to the development of operating revenue, perpetual growth rate and discount rate assumptions.
We performed sensitivity analyses over both the discount rate and the perpetual growth rate used in the discounted cash flow forecast to assess the impact of changes in these assumptions on the Group’s determination of the VIU of the fixed-line telecommunication services CGU.
 
Auditing management’s evaluation of goodwill impairment for the fixed-line telecommunication services CGU was complex due to the significant judgment involved in the management’s estimates of future operating revenue, perpetual growth rate and discount rate applied in determining the recoverable amount of the fixed-line telecommunication services CGU.
���
How We
Addressed the
Matter in Our
Audit
  
We obtained an understanding, evaluated the design, and tested the operating effectiveness, of controls over the Group’s goodwill impairment assessment process, including controls over management’s review of the significant assumptions described above.
To test the estimated recoverable amount of the Group’s fixed line telecommunication services CGU, we performed audit procedures that included, among others, sensitivity analyses over both the discount rate and the perpetual growth rate used in the discounted cash flow forecast to assess the impact of changes in these assumptions on the Group’s determination of the VIU of the fixed-line telecommunication services CGU. We also assessed the Group’s ability to make accurate forecast by comparing the historical projections with the actual results and evaluated the appropriateness of the estimated operating revenue by comparisoncomparing it with the financial budgets approved by the GroupGroup.
In addition, we involved our internal specialists to assist us in evaluating the reasonableness of: (1) the estimated operating revenue and perpetual growth rate by comparing the forecasted operating cash flow in prior yearthem with the actual results to assesstelecommunication industry reports as well as the Group’s ability to accurately forecast.historical performance; and (2) the discount rate by comparing it with a discount rate that was independently developed using publicly available market data for comparable entities.
We involved our valuation professionals with specialized skills and knowledge, who assisted in (1) evaluating estimated operating revenue and perpetual growth rate by comparing them with telecommunication industry reports as well as the Group’s historical performance and (2) evaluating the discount rate by comparing it with a discount rate that was independently developed using publicly available market data for comparable entities.

Basis for Opinion
The Group’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Group’s internal control over financial reporting based on our audit.

Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
 
F-4F-5

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

3)Fair value measurement
A number of the Group’s accounting policies and disclosures require the measurement of fair values, for both financial and
non-financial
assets and liabilities. The Group has an 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 IFRS, including the level in the fair value hierarchy in which such valuations should be classified.

Notes to the Consolidated Financial Statements — (Continued)
For the years ended December 31, 2021, 2020 and 2019
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 22 and note 35.

The Pillar Two model rules is scheduled to take effect for the Group’s fiscal year beginning January 1, 2024. As the Group falls within the scope of the enacted Pillar Two model rules, it has assessed the potential exposure to Pillar Two income tax. The assessment of potential exposure to Pillar Two income tax is based on the most recent tax returns of the Group’s consolidatedultimate controlling entity group, country-by-country reporting, and financial statements. The Group expects that the exposure to Pillar Two income tax will be immaterial.

(2)    Basis of consolidation
(a)    Business combination
(a)Business combination
A business combination is accounted for by applying the acquisition method, unless it is a combination involving entities or businesses under common control.
In determining whether a particular set of activities and assets is a business, the Group assesses whether the set of assets and activities acquired includes, at a minimum, an input and substantive process and whether the acquired set has the ability to produce outputs.
The Group has an option to apply a ‘concentration test’ that permits a simplified assessment of whether an acquired set of activities and assets is not a business. The optional concentration test is met if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets.

(a)Business combination, Continued
Consideration transferred is generally measured at fair value, identical to the measurement of identifiable net assets acquired at fair value. The difference between the acquired company’s fair value and the consideration transferred is accounted for goodwill. Any goodwill that arises is tested annually for impairment. Any gain on a bargain purchase is recognized in profit or loss immediately. Acquisition-related costs are expensed in the periods in which the costs are incurred and the services are received, except if related to the costs to issue debt or equity securities recognized based on IAS 32 and IFRS 9.
Consideration transferred does not include the amount settled in relation to the
pre-existing
relationship. Such amounts are generally recognized through profit or loss.
Contingent consideration is measured at fair value at the acquisition date. Contingent consideration classified as equity is not remeasured and its subsequent settlement is accounted for within equity. If contingent consideration is not classified as equity, the Group subsequently recognizes changes in fair value of contingent consideration through profit or loss.
(b)    Non-controlling
interests
(b)Non-controlling interests
Non-controlling
interests are measured at their proportionate share of the acquiree’s identifiable net assets at the date of acquisition.
Changes in a Controlling Company’s ownership interest in a subsidiary that do not result in the Controlling Company losing control of the subsidiary are accounted for as equity transactions.
(c)    Subsidiaries
(c)Subsidiaries
Subsidiaries are entities controlled by the Group. The Group controls an investee when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Consolidation of an investee begins from the date the Group obtains control of the investee and cease when the Group loses control of the investee.
(d)    Loss of control
(d)Loss of control
If the Group loses control of a subsidiary, the Group derecognizes the assets and liabilities of the former subsidiary from the consolidated statement of financial position and recognizes gain or loss associated with the loss

(e)    Interest in investees accounted for using the equity method
(e)Interest in investees accounted for using the equity method
Interest in investees accounted for using the equity method composed of interest in associates and joint ventures.
An associate is an entity in which the Group has significant influence, but not control, over the entity’s financial and operating policies. A joint venture is a joint arrangement whereby the Group that has joint control of the arrangement has rights to the net assets of the arrangement.

Intra-group balances and transactions, and any unrealized income and expenses arising from intra-group transactions, are eliminated in preparing the consolidated financial statements. The Group’s share of unrealized gain incurred from transactions with investees accounted for using the equity method are eliminated and unrealized loss are eliminated using the same basis if there are no evidence of asset impairments.
(g)    Business combinations under common control
(g)Business combinations under common control
SK Inc. is the ultimate controlling entity of the Group. The assets and liabilities acquired under business combination under common control are recognized at the carrying amounts in the ultimate controlling shareholder’s consolidated financial statements. The difference between consideration and

amount of net assets acquired is added to or subtracted from capital surplus and others.
(3)    Cash and cash equivalents

Cash and cash equivalents comprise cash balances, call deposits and investment securities with maturities of three months or less from the acquisition date that are easily convertible to cash and subject to an insignificant risk of changes in their fair value.
(4)    Inventories
(4)Inventories
Inventories are initially recognized at the acquisition cost and subsequently measured using the weighted average method. During the period, a perpetual inventory system is used to track inventory quantities, which is adjusted based on the physical inventory counts performed at the period end. When the net realizable value of inventories is less than cost, the carrying amount is reduced to the net realizable value, and any difference is charged to current period as operating expenses.

(b)Classification and subsequent measurement
On initial recognition, a financial asset is classified as measured at:
 
FVTPL
 
FVOCI equity investment
 
FVOCI debt investment
 
Financial assets at amortized cost
A financial asset is classified based on the business model in which a financial asset is managed and its contractual cash flow characteristics.
Financial assets are not reclassified subsequent to their initial recognition unless the Group changes its business model for managing financial assets, in which case all affected financial assets are reclassified on the first day of the first reporting period following the change in the business model.
A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as at FVTPL:
 
it is held within a business model whose objective is to hold assets to collect contractual cash flows; and
 
its contractual terms give rise to cash flows that are solely payments of principal and interest on the principal amount outstanding on specified dates.
A debt investment is measured at FVOCI if it meets both of the following conditions and is not designated as at FVTPL:
 
it is held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets; and
 
its contractual terms give rise to cash flows that are solely payments of principal and interest on the principal amount outstanding on specified dates.
On initial recognition of an equity investment that is not held for trading, the Group may irrevocably elect to present subsequent changes in the investment’s fair value in other comprehensive income (“OCI”). This election is made on an
investment-by-investment
basis.
All financial assets not classified as measured at amortized cost or FVOCI as described above are measured at FVTPL. This includes all derivative financial assets. On initial recognition, the Group may irrevocably designate a financial asset that otherwise meets the requirements to be measured at amortized cost or at FVOCI as at FVTPL if doing so eliminates or significantly reduces an accounting mismatch that would otherwise arise.

(b)Classification and subsequent measurement, Continued
The following accounting policies are applied to the subsequent measurement of financial assets.
 
Financial assets at FVTPL
  These assets are subsequently measured at fair value. Net gains and losses, including any interest or dividend income, are recognized in profit or loss.
Financial assets at amortized cost
  These assets are subsequently measured at amortized cost using the effective interest method. The amortized cost is reduced by impairment losses. Interest income, foreign exchange gains and losses and impairment are recognized in profit or loss. Any gain or loss on derecognition is recognized in profit or loss.
Debt investments at FVOCI
  These assets are subsequently measured at fair value. Interest income calculated using the effective interest method, foreign exchange gains and losses and impairment are recognized in profit or loss. Other net gains and losses are recognized in OCI. On derecognition, gains and losses accumulated in OCI are reclassified to profit or loss.
Equity investments at FVOCI
  These assets are subsequently measured at fair value. Dividends are recognized as income in profit or loss unless the dividend clearly represents a recovery of the cost of the investment. Other net gains and losses are recognized in OCI and are never reclassified to profit or loss.
(c)    Impairment
(c)Impairment
The Group estimates the expected credit losses (“ECL”) for the debt instruments measured at amortized cost and FVOCI based on the Group’s historical experience and informed credit assessment that includes forward-looking information. The impairment approach is decided based on the assessment of whether the credit risk of a financial asset has increased significantly since initial recognition. However, the Group applies a practical expedient and recognizes impairment losses equal to lifetime ECLs for accounts receivable – trade and lease receivables from the initial recognition.
ECL is a probability-weighted estimate of credit losses. Credit losses are measured as the present value of all cash shortfalls (i.e., the difference between the cash flows due to the entity in accordance with the contract and the cash flows that the Group expects to receive).
At each reporting date, the Group assesses whether financial assets measured at amortized cost and debt investments at FVOCI are credit-impaired. A financial asset is ‘credit-impaired’ when one or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred.

Financial assets
The Group derecognizes a financial asset when:
 
the contractual rights to the cash flows from the financial asset expire; or
 
it transfers the rights to receive the contractual cash flows in a transaction in which either:
 
substantially all of the risks and rewards of ownership of the financial asset are transferred; or
 
the Group neither transfers nor retains substantially all of the risks and rewards of ownership and it does not retain control of the financial asset.

The Group enters into transactions whereby it transfers assets recognized in its consolidated statement of financial position, but retains either all or substantially all of the risks and rewards of the transferred assets. In these cases, the transferred assets are not derecognized.
Interest rate benchmark reform
When the basis for determining the contractual cash flows of a financial asset or financial liability measured at amortized cost changed as a result of interest rate benchmark reform, the Group updated the effective interest rate of the financial asset or financial liability to reflect the change that is required by the reform. A change in the basis for determining the contractual cash flows is required by interest rate benchmark reform if the following conditions are met:
 
the change is necessary as a direct consequence of the reform; and
 
the new basis for determining the contractual cash flows is economically equivalent to the previous basis – i.e., the basis immediately before the change.
When changes were made to a financial asset or financial liability in addition to changes to the basis for determining the contractual cash flows required by interest rate benchmark reform, the Group first updated the effective rate of the financial asset or financial liability to reflect the change that is required by interest rate benchmark reform. After that, the Group applied the policies on accounting for modifications to the additional changes.
(e)    Offsetting
(e)Offsetting
Financial assets and financial liabilities are offset, and the net amount is presented in the statement of financial position when the Group currently has a legally enforceable right to offset the recognized amounts and it intends either to settle on a net basis or to settle the liability and realize the asset simultaneously.

(6)    Derivative financial instruments, including hedge accounting
(6)Derivative financial instruments, including hedge accounting
Derivatives are initially recognized at fair value. Subsequent to initial recognition, derivatives are measured at fair value at the end of each reporting period, and changes therein are accounted for as described below.
(a)    Hedge accounting
(a)Hedge accounting
The Group holds forward exchange contracts, interest rate swaps, currency swaps and other derivative contracts to manage interest rate risk and foreign exchange risk. The Group designates derivatives as hedging instruments to hedge the variability in cash flow associated with highly probable forecasted transactions or firm commitments (a cash flow hedge).
On initial designation of the hedge, the Group formally documents the relationship between the hedging instrument(s) and hedged item(s), including the risk management objectives and strategy in undertaking the hedge transaction, together with the methods that will be used to assess the effectiveness of the hedging relationship.
Hedges directly affected by interest rate benchmark reform
When uncertainty arises about the interest rate benchmark designated as a hedged risk and the timing or the amount of the interest rate
benchmark-based
cash flows of the hedged item or of the hedging instrument as a result of IBOR reform, for the purpose of evaluating whether there is an economic relationship between the hedged items and the hedging instruments, the Group assumes that the interest rate benchmark on which the hedged items and the hedging instruments are based is not altered as a result of interest rate benchmark reform.

For a cash flow hedge of a forecast transaction, the Group assumes that the benchmark interest rate will not be altered as a result of interest rate benchmark reform for the purpose of assessing whether the forecast transaction is highly probable and determining whether a previously designated forecast transaction in a discontinued cash flow hedge is still expected to occur.
The Group will cease applying the specific policy for assessing the economic relationship between the hedged item and the hedging instrument
 
to a hedged item or hedging instrument when the uncertainty arising from interest rate benchmark reform is no longer present with respect to the timing and the amount of the interest rate
benchmark-based
cash flows of the respective item or instrument; or
 
when the hedging relationship is discontinued.

(a)Hedge accounting, Continued
When the basis for determining the contractual cash flows of the hedged item or hedging instrument changes as a result of IBOR reform and therefore there is no longer uncertainty arising about the cash flows of the hedged item or the hedging instrument, the Group amends the hedge documentation of that hedging relationship to reflect the change(s) required by IBOR reform.
The Group amends the formal hedge documentation by the end of the reporting period during which a change required by IBOR reform is made to the hedged risk, hedged item or hedging instrument. These amendments in the formal hedge documentation do not constitute the discontinuation of the hedging relationship or the designation of a new hedging relationship.
If changes are made in addition to those changes required by interest rate benchmark reform to the financial asset or financial liability designated in a hedging relationship or to the designation of the hedging relationship, the Group determines whether those additional changes result in the discontinuation of hedging accounting. If the additional changes do not result in the discontinuation of hedging accounting, the Group amend the formal designation of the hedging relationship.
When the interest rate benchmark on which the hedged future cash flows had been based is changed as required by IBOR reform, for the purpose of determining whether the hedged future cash flows are expected to occur, the Group deems that the hedging reserve recognized in OCI for that hedging relationship is based on the alternative benchmark rate on which the hedged future cash flows will be based.
Cash flow hedge
When a derivative is designated to hedge the variability in cash flows attributable to a particular risk associated with a recognized asset or liability or a highly probable forecasted transaction that could affect profit or loss, the effective portion of changes in the fair value of the derivative is recognized in other comprehensive income, net of tax, and presented in the hedging reserve in equity. Any ineffective portion of changes in the fair value of the derivative is recognized immediately in profit or loss. If the hedging instrument no longer meets the criteria for hedge accounting, expires or is sold, terminated, exercised, or the designation is revoked, then hedge accounting is discontinued prospectively. The cumulative gain or loss on the hedging instrument that has been recognized in other comprehensive income is reclassified to profit or loss in the periods during which the forecasted transaction occurs. If the forecasted transaction is no longer expected to occur, then the balance in other comprehensive income is recognized immediately in profit or loss.
(b)    Other derivative financial instruments

Other derivative financial instrument not designated as a hedging instrument are measured at fair value, and the changes in fair value of the derivative financial instrument is recognized immediately in profit or loss.

(7)    Property and equipment
(7)Property and equipment
Property and equipment are initially measured at cost. The cost of property and equipment includes expenditures arising directly from the construction or acquisition of the asset, any costs directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management and the initial estimate of the costs of dismantling and removing the item and restoring the site on which it is located.
Property and equipment, subsequently, are carried at cost less accumulated depreciation and accumulated impairment losses.
Subsequent costs are recognized in the carrying amount of property and equipment at cost or, if appropriate, as a separate item if it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be reliably measured. The carrying amount of the replaced part is derecognized. The costs of the
day-to-day
servicing are recognized in profit or loss as incurred.
Property and equipment, except for land, are depreciated on a straight-line basis over estimated useful lives that appropriately reflect the pattern in which the asset’s future economic benefits are expected to be consumed. A component that is significant compared to the total cost of property and equipment is depreciated over its separate useful life.
Gains and losses on disposal of an item of property and equipment are determined by comparing the proceeds from disposal with the carrying amount of property and equipment and are recognized as other
non-operating
operating income (loss).or expense.
The estimated useful lives of the Group’s property and equipment are as follows:
 
   
Useful lives (years)
Buildings and structures
  15 ~ 40
Machinery
  3 ~ 15, 30
Other property and equipment
  3~3 ~ 10
Right-of-use

  1 ~ 50
Depreciation methods,The Group reviews estimated residual values, expected useful lives, and residual values are revieweddepreciation methods annually at the end of each reporting date and adjusted,adjusts, if appropriate. The change is accounted for as a change in an accounting estimate.
(8)    Borrowing costs
The Group capitalizes borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset as part of the cost of that asset. Other borrowing costs are recognized in expense as incurred. A qualifying asset is an asset that requires a substantial period of time to get ready for its intended use or sale. Financial assets are not qualifying assets, and assets that are ready for their intended use or sale when acquired are not qualifying assets either.
To the extent that the Group borrows funds specifically for the purpose of obtaining a qualifying asset, the Group determines the amount of borrowing costs eligible for capitalization as the actual borrowing costs incurred on that borrowing during the period less any investment income on the temporary investment of those borrowings. To the extent that the Group borrows funds generally and uses them for the purpose of obtaining a qualifying asset, the Group determines the amount of borrowing costs eligible for capitalization by applying a capitalization rate to the expenditures on that asset. The capitalization rate is the weighted average of the borrowing costs applicable to the borrowings of the Group that are outstanding during the period other than borrowings made specifically for the purpose of obtaining a qualifying asset. The amount of borrowing costs that the Group capitalizes during a period do not exceed the amount of borrowing costs incurred during the period.

Intangible assets are measured initially at cost and, subsequently, are carried at cost less accumulated amortization and accumulated impairment losses.
Intangible assets, except for goodwill, are amortized on a straight-line basis over the estimated useful lives of intangible assets from the date that they are available for use. The residual value of intangible assets is zero. However, club memberships and brand are expected to be available for use as there are no foreseeable limits to the periods. These intangible assets are determined as having indefinite useful lives and, therefore, not amortized.

Amortization periods and the amortization methods for intangible assets with finite useful lives are reviewed at the end of each reporting period. The useful lives of intangible assets that are not being amortized are reviewed at the end of each reporting period to determine whether events and circumstances continue to support indefinite useful life assessments for those assets. Changes, if appropriate, are accounted for as changes in accounting estimates.
Expenditures on research activities are recognized in profit or loss as incurred. Development expenditures are capitalized only if development costs can be reliably measured, the product or process is technically and commercially feasible, future economic benefits are probable, and the Group intends to and has sufficient resources to complete development and to use or sell the asset. Other development expenditures are recognized in profit or loss as incurred.
Subsequent expenditures are capitalized only when they increase the future economic benefits embodied in the specific asset to which it relates. All other expenditures, including expenditures on internally generated goodwill and brands, are recognized in profit or loss as incurred.
(10)    Government grants
Government grants are not recognized unless there is reasonable assurance that the Group will comply with the grant’s conditions and that the grant will be received.
1)    Grants related to assets
Government grants whose primary condition is that the Group purchases, constructs, or otherwise acquires a long-term asset are deducted in calculating the carrying amount of the asset. The grant is recognized in profit or loss over the life of a depreciable asset as a reduction to depreciation expense.
2)    Grants related to income
Government grants which are intended to compensate the Group for expenses incurred are deducted from the related expenses.

(9)Investment property
Investment properties are properties held to earn rentalsrent income and/or for capital appreciation. Investment properties are measured initially at cost, including transaction costs. Subsequent to initial recognition, investment properties are reported at cost less accumulated depreciation and accumulated impairment losses.
Subsequent expenditures are recognized in carrying amount of an asset or as a separate asset if it is probable that future economic benefits associated with the assets will flow into the Group and the cost of an asset can be measured reliably. The carrying amount of those parts that are replaced is derecognized. The costs associated with routine maintenance and repairs are recognized in profit or loss as incurred.
Investment property, except for land, is depreciated on a straight-line basis over estimated useful lives of 30 years. In addition,
right-of-use
asset classified as investment property is depreciated using the
straight-line
basis from the commencement date to the end of the lease term.
The depreciation method, estimated useful lives and residual values are reviewed at the end of each reporting date and adjusted, if appropriate. The change is accounted for as a change in an accounting estimate.

(10)Impairment of non-financial assets
The carrying amounts of the Group’s
non-financial
assets other than contract assets recognized for revenue arising from contracts with a customer, assets recognized for the costs to obtain or fulfill a contract with a customer, employee benefits, inventories, deferred tax assets, and
non-current
assets held for sale are reviewed at the end of the reporting period to determine whether there is any indication of impairment. If any such indication exists, then the asset’s recoverable amount is estimated. Goodwill and intangible assets that have indefinite useful lives or that are not yet available for use, irrespective of whether there is any indication of impairment, are tested for impairment annually by comparing their recoverable amounts to their carrying amounts.
The Group estimates the recoverable amount of an individual asset, and if it is impossible to measure the individual recoverable amount of an asset, the Group estimates the recoverable amount of cash-generating unit (“CGU”). A CGU is the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets. The recoverable amount of an asset or CGU is the greater of its value in use and its fair value less costs to sell. The value in use is estimated by applying a
pre-tax
discount rate that reflects current market assessments of the time value of money and the risks specific to the asset or CGU for which estimated future cash flows have not been adjusted, to the estimated future cash flows expected to be generated by the asset or CGU.
An impairment loss is recognized in profit or loss to the extent the carrying amount of the asset exceeds its recoverable amount.
Goodwill acquired in a business combination is allocated to each CGU that is expected to benefit from the synergy arising from the business acquired. Any impairment identified at the CGU level will first reduce the carrying amount of goodwill and then be used to reduce the carrying amount of the other assets in the CGU on a pro rata basis. Except for impairment losses in respect of goodwill which are never reversed, an impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount. An impairment loss is reversed only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized.

At commencement or on modification of a contract that contains a lease component, the Group allocates the consideration in the contract to each lease component on the basis of its relative stand-alone prices. However, the Group has elected not to separate

components and account for the lease and
non-lease
components as a single lease component.
The Group recognizes a
right-of-use
asset and a lease liability at the lease commencement date. The
right-of-use
asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred and an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset or the site on which it is located, less any lease incentives received.

(a)Group as a lessee, Continued
The right-of-use asset is subsequently depreciated using the
straight-line
basis from the commencement date to the end of the lease term, unless the lease transfers ownership of the underlying asset to the Group by the end of the lease term or the cost of the
right-of-use
asset reflects that the Group will exercise a purchase option. In that case the
right-of-use
asset will be depreciated over the useful life of the underlying asset, which is determined on the same basis as those of property and equipment. In addition, the
right-of-use
asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability.
The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Group’s incremental borrowing rate. Generally, the Group uses its incremental borrowing rate as the discount rate.
The Group determines its incremental borrowing rate by obtaining interest rates from various external financing sources and makes certain adjustments to reflect the terms of the lease and type of the asset leased.
Lease payments included in the measurement of the lease liability comprise the following:
 
fixed payments, including
in-substance
fixed paymentspayments;
 
variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the commencement datedate;
 
amounts expected to be payable under a residual value guaranteeguarantee; and
 
the exercise price under a purchase option that the Group is reasonably certain to exercise, lease payments in an optional renewal period if the Group is reasonably certain to exercise an extension option, and penalties for early termination of a lease unless the Group is reasonably certain not to terminate early.
The lease liability is measured at amortized cost using the effective interest method. It is remeasured when there is a change in future lease payments arising from a change in an index or rate, if there is a change in the Group’s estimate of the amount expected to be payable under a residual value guarantee, if the Group changes its assessment of whether it will exercise a purchase, extension or termination option or if there is a revised
in-substance
fixed lease payment.
When the lease liability is remeasured in this way, a corresponding adjustment is made to the carrying amount of the
right-of-use
asset, or is recorded in profit or loss if the carrying amount of the
right-of-use
asset has been reduced to zero.
The Group presents
right-of-use
assets that do not meet the definition of investment property in ‘property and equipment’ in the statement of financial position.
The Group has elected not to recognize
right-of-use
assets and lease liabilities for leases of
low-value
assets and short-term leases. The Group recognizes the lease payments associated with leaseon short-term leases and leases of low value assets as an expense on a
straight-line
basis over the lease term.

(b)    As a lessor
(b)Group as a lessor
At inception or on modification of a contract that contains a lease component, the Group allocates the consideration in the contract to each lease component on the basis of their relative stand-alone prices.
When the Group acts as a lessor, it determines at lease inception whether each lease is a finance lease or an operating lease.
To classify each lease, the Group makes an overall assessment of whether the lease transfers substantially all of the risks and rewards incidental to ownership of the underlying asset. If this is the case, then the lease is a finance lease; if not, then it is an operating lease. As part of this assessment, the Group considers certain indicators such as whether the lease is for the major part of the economic life of the asset.
When the Group is an intermediate lessor, is accounts for its interests in the head lease and the
sub-lease
separately. It assesses the lease classification of a
sub-lease
with reference to the
right-of-use
asset arising from the head lease, not with reference to the underlying asset. If a head lease is a short-term lease to which the Group applies the exemption described above, then it classifies the
sub-lease
as an operating lease.
If an arrangement contains lease and
non-lease
components, then the Group applies IFRS 15 to allocate the consideration in the contract.
The Group applies derecognition and impairment requirements in IFRS 9 to the net investment in the lease. The Group further regularly reviews estimated unguaranteed residual values used in calculating the gross investment in the lease.
The Group recognizes lease payments received under operating leases as income on a straight-line basis over the lease term as part of ‘other revenue’.
(14)    Non-current
assets held for sale
(12)Non-current assets held for sale
Non-current
assets, or disposal groups comprising assets and liabilities, that are expected to be recovered primarily through sales rather than through continuing use, are classified as held for sale. In order to be classified as held for sale, the assets (or disposal groups) must be available for immediate sale in their present condition and their sale must be highly probable. The assets or disposal groups that are classified as
non-current
assets held for sale are measured at the lower of their carrying amounts and fair value less cost to sell. The Group recognizes an impairment loss for any initial or subsequent write-down of assets (or disposal groups) to fair value less costs to sell and a gain for any subsequent increase in fair value less costs to sell up to the cumulative impairment loss previously recognized in accordance with IAS 36,
Impairment of Assets

When a financial liability is derecognized, the difference between the carrying amount and the consideration paid (including any transferred
non-cash
assets or liabilities assumed) is recognized in profit or loss.

(b)Other long-term employee benefits
Other long-term employee benefits include employee benefits that are settled beyond 12 months after the end of the period in which the employees render related services. The Group’s net obligation in respect of long-term employee benefits is the amount of future benefit that employees have earned in return for their service in the current and prior periods. That benefit is discounted to determine its present value. Remeasurements are recognized in profit or loss in the period in which they arise.
(c)    Retirement benefits: defined contribution plans
(c)Retirement benefits: defined contribution plans
When an employee has rendered a service to the Group during a period, the Group recognizes the contribution payable to a defined contribution plan in exchange for that service as a liability (accrued expense), after deducting any contribution already paid. If the contribution already paid exceeds the contribution due for service before the end of the reporting period, the Group recognizes that excess as an asset (prepaid expense) to the extent that the prepayment will lead to a reduction in future payments or a cash refund.
(d)Retirement benefits: defined benefit plans
(d)    Retirement benefits: defined benefit plans
At the end of reporting period, defined benefit liabilities (assets) relating to defined benefit plans are recognized at present value of defined benefit obligations net of fair value of plan assets.
The calculation is performed annually by an independent actuary using the projected unit credit method. When the fair value of plan assets exceeds the present value of the defined benefit obligation, the Group recognizes an asset, to the extent of the present value of any economic benefits available in the form of refunds from the plan or reduction in the future contributions to the plan.

Remeasurements of the net defined benefit liability (asset), which comprise actuarial gains and losses, the return on plan assets (excluding interest) and the effect of the asset ceiling (if any, excluding interest), are recognized immediately in other comprehensive income. The Group determines net interests on net defined benefit liability (asset) by multiplying discount rate determined at the beginning of the annual reporting period and considers changes in net defined benefit liability (asset) from contributions and benefit payments. Net interest costs and other costs relating to the defined benefit plan are recognized through profit or loss.
When the plan amendment or curtailment occurs, gains or losses on amendment or curtailment in benefits for the past service provided are recognized through profit or loss. The Group recognizes a gain or loss on a settlement when the settlement of defined benefit plan occurs.
(e)    Termination benefits
The Group recognizes a liability and expense for termination benefits at the earlier of the period when the Group can no longer withdraw the offer of those benefits and the period when the Group recognizes costs for a restructuring that involves the payment of termination benefits. If benefits are payable more than 12 months after the reporting period, they are discounted to their present value.
(17)    Provisions
(15)Provisions
Provisions are recognized when the Group has a present legal or constructive obligation as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation.
The risks and uncertainties that inevitably surround many events and circumstances are taken into account in reaching the best estimate of a provision. If the effect of the time value of money is material, provisions are determined at the present value of the expected future cash flows.

(15)Provisions, Continued
If some or all of the expenditures required to settle a provision are expected to be reimbursed by another party, the reimbursement is recognized when, and only when, it is virtually certain that reimbursement will be received if the entity settles the obligation. The reimbursement is treated as a separate asset.
Provisions are reviewed at the end of each reporting period and adjusted to reflect the current best estimates. If it is no longer probable that an outflow of resources embodying economic benefits will be required to settle the obligation, the provision is reversed.
A provision is used only for expenditures for which the provision was originally recognized.
(18)    Emissions Rights
(16)Emissions Rights
The Group accounts for greenhouse gases emission right and the relevant liability as below pursuant to the Act on Allocation and Trading of Greenhouse Gas Emission in Korea.
1)    Greenhouse Gases Emission Right
(a)Greenhouse Gases Emission Right
Greenhouse Gases Emission Right consists of emission allowances, which are allocated from the government free of charge or purchased from the market. The cost includes any directly attributable costs incurred during the normal course of business.
The Group derecognizes an emission right asset when the emission allowance is unusable, disposed or submitted to government in which the future economic benefits are no longer expected to be probable.

(b)Emissions liability
Emission liability is a present obligation of submitting emission rights to the government with regard to emission of greenhouse gas. The emission liability is measured based on the expected quantity of emission for the performing period in excess of emission allowance in possession and the unit price for such emission rights in the market at the end of the reporting period. The emissions liabilities are derecognized when they are surrendered to the government.

(a)Foreign currency transactions
Transactions in foreign currencies are translated to the functional currency of the Group at exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are retranslated to the functional currency using the exchange rate at the reporting date.
Non-monetary
assets and liabilities denominated in foreign currencies that are measured at fair value are retranslated to the functional currency at the exchange rate at the date that the fair value was determined.
Exchange differences arising from monetary items except for financial liabilities designated cashflow hedging instruments are recognized in profit or loss. If a gain or loss on a non-monetary item is recognized in other comprehensive income, any foreign exchange differences are also recognized in other comprehensive income. When a gain or loss on a non-monetary item is recognized in profit or loss, any foreign exchange differences are also recognized in profit or loss.

(b)Foreign operations
If the presentation currency of the Group is different from a foreign operation’s functional currency, the financial statements of the foreign operation are translated into the presentation currency using the following methods:
The assets and liabilities of foreign operations, whose functional currency is not the currency of a hyperinflationary economy, are translated to presentation currency at exchange rates at the reporting date. The income and expenses of foreign operations are translated to functional currency at exchange rates at the dates of the transactions. Foreign currency differences are recognized in other comprehensive income.
Any goodwill arising on the acquisition of a foreign operation and any fair value adjustments to the carrying amounts of assets and liabilities arising on the acquisition of that foreign operation is treated as assets and liabilities of the foreign operation. Thus, they are expressed in the functional currency of the foreign operation and translated at the closing rate at the reporting date.
When a foreign operation is disposed, the relevant amount in the translation is transferred to profit or loss as part of the profit or loss on disposal. On the partial disposal of a subsidiary that includes a foreign operation, the relevant proportion of such cumulative amount is reattributed to
non-controlling
interest. In any other partial disposal of a foreign operation, the relevant proportion is reclassified to profit or loss.
(20)    Share capital
(18)Share capital
Ordinary shares are classified as equity. Incremental costs directly attributable to the issuance of ordinary shares and share options are recognized as a deduction from equity, net of any tax effects.
When the Parent Company repurchases its own shares, the amount of the consideration paid is recognized as a deduction from equity and classified as treasury shares. The gains or losses from the purchase, disposal, reissue, or retirement of treasury shares are directly recognized in equity being as transaction with owners.

The related expense with a corresponding increase in capital surplus and others is recognized over the vesting period of the awards.
The amount recognized as an expense is adjusted to reflect the number of awards for which the related service and
non-market
performance conditions are expected to be met, such that the amount ultimately recognized is based on the number of awards that meet the related service and
non-market
performance conditions at the vesting date.

The fair value of the amount payable to employees in respect of share appreciation rights, which are settled in cash, is recognized as an expense with a corresponding increase in liabilities, over the period in which the employees become unconditionally entitled to payment. The liability is remeasured at each reporting date and at settlement date based on the fair value of the share appreciation rights. Any changes in the fair value of the liability are recognized in profit or loss.

(a)    Identification of performance obligations in contracts with customers
(a)Identification of performance obligations in contracts with customers
The Group identifies the distinct services or goods as performance obligations in contracts with customers such as (1) providing wireless and fixed-line telecommunications services, (2) sale of handsets and (3) providing other goods and services. In the case of providing both wireless telecommunications service and selling a handset together to one customer, the Group allocates considerations from the customer between the separate performance obligations for handset sale and wireless telecommunications service. The handset sale revenue is recognized when handset is delivered, and the wireless telecommunications service revenue is recognized over the period of the contract term as stated in the subscription contract.
(b)    Allocation of the transaction price to each performance obligation
(b)Allocation of the transaction price to each performance obligation
The Group allocates the transaction price of a contract to each performance obligation identified on a relative stand-alone selling price basis. The Group uses “adjusted market assessment approach” for estimating the stand-alone selling price of a good or service.
(c)    Incremental costs of obtaining a contract
(c)Incremental costs of obtaining a contract
The Group pays commissions to its retail stores and authorized dealers in connection with acquiring service contracts. The commissions paid to these parties constituted a significant portion of the Group’s operating expenses. These commissions would not have been paid if there have been no binding contracts with subscribers and, therefore, the Group capitalizes certain costs associated with commissions paid to obtain new customer contracts and amortize them over the expected contract periods.
(d)    Customer loyalty programs
(d)Customer loyalty programs
The Group provides customer loyalty points to customers based on the usage of the service to which the Group allocates a portion of consideration received as a performance obligation distinct from wireless telecommunications services. The amount to be allocated to the loyalty program is measured according to the relative stand-alone selling price of the customer loyalty points. The amount allocated to the loyalty program is deferred as a contract liability and is recognized as revenue when loyalty points are redeemed.

(e)Consideration payable to a customer
Based on the subscription contract, a customer who uses the Group’s wireless telecommunications services may receive a discount for purchasing goods or services from a designated third party. The Group pays a portion of the price discounts that the customer receives to the third party which is viewed as consideration payable to a customer. The Group accounts for the amounts payable to the third party as a reduction of the wireless
telecommunications
service revenue.
(24)    Finance income and finance costs
(22)Finance income and finance costs
Finance income comprises interest income on funds invested (including financial assets measured at fair value), dividend income, gains on disposal of financial assets at FVTPL, changes in fair value of financial instruments at FVTPL, and gains on hedging instruments that are recognized in profit or loss. Interest income is recognized as it accrues in profit or loss, using the effective interest rate method. Dividend income is recognized in profit or loss when the right to receive the dividend is established.
Finance costs comprise interest expense on borrowings and debentures, changes in fair value of financial instruments at FVTPL, and losses on hedging instruments that are recognized in profit or loss. Interest expense on borrowings and debentures is recognized as it accrues in profit or loss using the effective interest rate method.
(25)    Income taxes
(23)Income taxes
Income tax expense comprises current and deferred tax. Current tax and deferred tax are recognized in profit or loss except to the extent that it relates to a business combination, or items recognized directly in equity or in OCI.
The Group pays income tax in accordance with the
tax-consolidation
system when the Parent Company and its subsidiaries are economically unified.
(a)    Current tax
(a)Current tax
Current tax is the expected tax payable or receivable on the taxable profit or loss for the year, using tax rates enacted or substantively enacted at the end of the reporting period, and includes interests and fines related to income taxes paid or payable. The taxable profit is different from the accounting profit for the period since the taxable profit is calculated excluding the temporary differences, which will be taxable or deductible in determining taxable profit (tax loss) of future periods, and
non-taxable
or
non-deductible
items from the accounting profit.
(b)    Deferred tax
(b)Deferred tax
Deferred tax is recognized by using the asset-liability method in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. The Group recognizes a deferred tax liability for all taxable temporary differences, except for the difference associated with investments in subsidiaries and associates that the Group is able to control the timing of the reversal of the temporary difference and it is probable that the

temporary difference will not reverse in the foreseeable future. The Group recognizes a deferred tax asset for all deductible temporary differences to the extent that it is probable that the temporary difference will reverse in the foreseeable future and taxable profit will be available against which the temporary difference can be utilized.
A deferred tax asset is recognized for the carryforward of unused tax losses and unused tax credits to the extent that it is probable that future taxable profit will be available against which the unused tax losses and unused tax credits can be utilized. Future taxable profit is dependent on the reversal of taxable temporary differences. If there are insufficient taxable temporary differences to recognize the deferred tax asset, the business plan of the Group and the reversal of existing temporary differences are considered in determining the future taxable profit.

SK TELECOM CO., LTD. and Subsidiaries
Notes to the Consolidated Financial Statements — (Continued)
For the years ended December 31, 2021, 2020 and 2019
The Group reviews the carrying amount of a deferred tax asset at the end of each reporting period and reduces the carrying amount to the extent that it is no longer probable that sufficient taxable profit will be available to allow the benefit of part or all of that deferred tax asset to be utilized.
Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realized, or the liability is settled based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred tax liabilities and deferred tax assets reflects the tax consequences that would follow from the manner in which the Group expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.
Deferred tax assets and liabilities are offset only if the Group has a legally enforceable right to offset the amount recognized and intends to settle the current tax liabilities and assets on a net basis. Income tax expense in relation to dividend payments is recognized when liabilities relating to the dividend payments are recognized.
(c)    Uncertainty over income tax treatments
(c)Uncertainty over income tax treatments
The Group assesses the uncertainty over income tax treatments pursuant to IAS 12. If the Group concludes it is not probable that the taxation authority will accept an uncertain tax treatment, the Group reflects the effect of uncertainty for each uncertain tax treatment by using either of the following methods, depending on which method the entity expects to better predict the resolution of the uncertainty:
 
The most likely amount: the single most likely amount in a range of possible outcomes.
 
The expected value: the sum of the
probability-weighted
amounts in a range of possible outcomes.
(26)    Earnings per share
(24)Earnings per share
The Group presents basic and diluted earnings per share (EPS) data for its ordinary shares. Basic EPS is calculated by dividing the profit or loss attributable to ordinary shareholders of the Parent Company by the weighted average number of ordinary shares outstanding during the period, adjusted for own shares held. Diluted EPS is determined by adjusting the profit or loss attributable to ordinary shareholders and the weighted average number of ordinary shares outstanding, adjusted for own shares held, for the effects of all dilutive potential ordinary shares, which comprise share options granted to employees, if any.

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. Details of loss allowance on accounts receivable trade as of December 31, 20212023 are as follows:

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 rating. While the contract assets are under the impairment requirements, no significant credit risk has been identified.

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.

Interest rate benchmark reform and associated risks
A fundamental reform of major interest rate benchmarks is being undertaken globally, including the replacement of some interbank offered rates (IBORs) with alternative nearly risk-free rates (referred to as ‘IBOR

reform’). Especially, in the case of LIBOR, all of the calculations were suspended as of December 31, 2021, except for the overnight, one month, three months, six months, and 12 months of USD LIBOR, and the aforementioned five USD LIBORs will also be suspended as of June 30, 2023. The alternative interest rate benchmark of USD LIBOR is the Secured Overnight Financing Rate(“SOFR”). Meanwhile, inIn case of Korean CD rate, the alternative interest rate benchmark has selected as Korea Overnight Financing Repo Rate(“KOFR”) and as part of interest rate benchmark reform, the interest rate has been disclosed through Korea Securities Depository since November 26, 2021. KOFR is calculated using the overnight RP rate as collateral for government bonds and monetary stabilization bonds. However, unlike LIBOR, calculation of CD rate will not be suspended, thereby making it is unclear when and how the transition to KOFR will take place.
Non-derivative financial liabilities
The Group plansParent Company’s non-derivative financial liabilities subject to include fallback clauses into financial instruments relating to LIBOR to which calculation has not been suspended yet, or change their LIBOR directly to alternative interest rates before the calculation is suspended. Meanwhile, The Group is closely monitoring market trends for CD rate-related financial instruments.
The Group’s financial instruments exposed to the risk arising from interest rate benchmark reform as of December 31, 2021 are indexed to the USD LIBOR. The Group is exposed to legal risk to amend the terms of contracts on the financial instruments subject to interest rate benchmark reform as well as process and operation risks to manage such amendments. In addition, the Group is exposed to the risk of monitoring the market trend regarding the alternative interest rate and establishing the corresponding risk management strategy. If the IBOR is designated as the hedged item, the Group is required to replace it to an alternative benchmark interest and review the effects on the hedging relationship. In addition, the Group is exposed to the risk of minimizing hedge ineffectiveness by aligning the method and timing of the transition to the alternative benchmark interest applied to the hedged item and the hedging instrument.
The Group evaluates the extent to which contracts reference IBOR cash flows, whether such contracts will need to be amended as a result of IBOR reform and how to manage communication about IBOR reform with counterparties.
Non-derivative
financial liabilities
The Parent Company’s
non-derivative
financial liabilities subject to Interest rate benchmark reform as of December 31, 20202022 were floating-rate bonds indexed to USD LIBOR. As explained above, theThe Group is discussingcompleted discussion with the counterparty about including the fallback clauses as of December 31, 2021.2023.
Derivatives
TheMost of the Group’s most derivative instruments designated as cash flow hedge are governed by contracts based on the International Swaps and Derivatives Association (ISDA)(“ISDA”)’s master agreements. As part of interest rate benchmark reform, ISDA has included a new fallback clause regarding which alterativealternative benchmark interest rate to be applied when the calculation of major IBOR is suspended in the master agreement. The master agreement is applied to derivative contracts executed after January 25, 2021, and the transaction parties isare required to adhere to ISDA protocol to include the same fallback clause tointo derivative contracts executed before January 25, 2021. The Group has adhered to ISDA protocol for transition to the alternative benchmark interest rate and the fallback clause will be included when counterparties adhere to the protocol to include. The Group’s counterparties have adhered to ISDA protocol and agreed to include the fallback clause.
Hedge accounting
The Group’s hedged items and hedging instruments as of December 31, 2021 are indexed to USD LIBOR. These benchmark rates are quoted each day and the IBOR cash flows are exchanged with counterparties as usual.

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 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.
(i) Accounts receivable trade and contract assets
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. Details of changes in loss allowance
for
the year ended December 31, 20212023 are included in note 6.

W
1,195,9171,055,102 million of loans and other receivables. To limit the exposure to this risk, the Group transacts only with financial institutions with credit ratings that are considered to be low credit risk.
Most of the Group’s debt investments are considered to have a low risk of default and the borrower has a strong capacity to meet its contractual cash flow obligations in the near term. Thus, the Group measured the loss allowance for the debt investments at an amount equal to
12-month
expected credit losses.
Meanwhile, the Group monitors changes in credit risk at each reporting date. The Group recognized the loss allowance at an amount equal to lifetime expected credit losses when the credit risk on the debt investments is assumed to have increased significantly if it is more than 30 days past due.

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 December 31, 20212023 are as follows:
 
   
Interest rate
Derivative instruments  0.32%2.18% ~ 3.90%6.25%
Borrowings and debentures  1.64%3.84% ~ 2.33%18.12%

Report of Independent Registered Public Accounting Firm
To the Board of Directors and Shareholders
SK hynix, Inc.:
Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated statements of financial position of SK hynix, Inc. and subsidiaries (the Group) as of October 31, 2021 and December 31, 2020, the related consolidated statements of comprehensive income, changes in equity and cash flows for the
10-month
period ended on October 31, 2021 and each of the years in the
two-year
period ended on December 31, 2020 and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Group as of October 31, 2021 and December 31, 2020, and the results of its operations and its cash flows for the
10-month
period ended on October 31, 2021 and for each of the years in the
two-year
period ended on December 31, 2020, in conformity with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board.
Basis for Opinion
These consolidated financial statements are the responsibility of the Group’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Group in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Measurement of fair values of long-term investment assets related to KIOXIA Holdings Corporation (“KIOXIA”)
As discussed in Note 6 and Note 12 to the consolidated financial statements, the Group holds ₩ 3,823,456 million of equity investment in BCPE Pangea Intermediate Holdings Cayman, L.P. (“SPC1”), and ₩ 2,521,342 million of convertible bonds investment in BCPE Pangea Cayman2 Limited (“SPC2”), as of October 31, 2021. Fair values of these long-term investment assets are measured based on the equity value of KIOXIA Holdings Corporation (“KIOXIA”). Specifically, the fair value of equity investment in SPC1 is measured using an option pricing model allocating the estimated fair value of KIOXIA equity between investors, together with consideration of expected KIOXIA initial public offering and SPC1 liquidation. The fair value of convertible bonds investment in SPC2 is measured based on the estimated KIOXIA’s equity value and SPC2’s equity ownership in KIOXIA.
G-1

We identified the measurement of fair values of long-term investment assets related to KIOXIA as a critical audit matter. Estimation of equity value of KIOXIA, an unlisted company, and fair values of the financial instruments in SPC1 and SPC2 involved the application of significant judgment and measurement uncertainty therefore requires a high degree of auditor judgment, and involvement of professionals with specialized skill and knowledge. Specifically, the assumptions of estimated future revenue, operating profit, discount rate, and volatility of KIOXIA’s equity value, and the expected timing of liquidation of SPC1 were challenging to test and involved subjective auditor judgment.
The following are the primary procedures we performed to address this critical audit matter. We evaluated the design of certain internal control related to the process over measurement of fair values of long-term investment assets related to KIOXIA. This included controls related to the development of estimated future revenue, operating profit, expected timing of liquidation of SPC1, discount rate, and volatility assumptions. We compared key assumptions of estimated future revenue, and operating profit used in the forecasted cash flow in prior year to the actual results in current year to assess the Group’s ability to accurately forecast. We performed sensitivity analyses over discount rate, volatility of KIOXIA’s equity value, and expected timing of liquidation of SPC1 to assess the impact of changes in those assumptions on the fair values measurement. We involved our valuation professionals with specialized skills and knowledge, who assisted us in the following:
assessing the estimated future revenue, operating profit, and expected timing of liquidation of SPC1 by comparing them with relevant industry data;
assessing the reasonableness of the comparable companies used by the Group in determining the discount rate;
assessing the volatility of KIOXIA’s equity value by comparing it against the volatilities for other public comparable companies.

2.    Basis of Preparation
The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”), as issued by the International Accounting Standards Board (IASB). In accordance with
Rule 3-09
of Regulation
S-X,
full financial statements of significant equity investments are required to be presented in the annual report of the investor. For purposes of
S-X
3-09,
the investee’s separate annual financial statements should only depict the period of the fiscal year in which it was accounted for by the equity method by the investor. As SK Square Co., Ltd., a new
spin-off
corporation established by SK Telecom Co., Ltd., succeeded the entire share of the Parent Company held by SK Telecom Co., Ltd. on November 2, 2021, the current year’s financial statements are prepared for the period from January 1, 2021 to October 31, 2021. Meanwhile, the comparatives financial statements are prepared for the years ended December 31, 2020 and 2019.

Notes to the Consolidated Financial Statements
For the period from January 1, 2021 to October 31, 2021 and for the years ended December 31, 2020 and 2019
2.    Basis of Preparation,  continued
The consolidated financial statements were authorized for issuance by Parent Company’s management on April 28, 2022.
(1)    Basis of measurement
The consolidated financial statements have been prepared on the historical cost basis, except for the following material items in the consolidated statements of financial position:
derivative financial instruments are measured at fair value
financial instruments at fair value through profit or loss and other comprehensive income or loss are measured at fair value
assets or liabilities for defined benefit plans are recognized at the net of the total present value of defined benefit obligations less the fair value of plan assets
(2)    Functional and presentation currency
Financial statements of entities within the Group are presented in functional currency and the currency of the primary economic environment in which each entity operates. Consolidated financial statements of the Group are presented in Korean won, which is the Parent Company’s functional and presentation currency.
(3)    Use of estimates
The preparation of the consolidated financial statements in conformity with 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.
Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected.
(a)    Judgments
Information about critical judgments in applying accounting policies that have the significant effect on the amounts recognized in the consolidated financial statements is included in the note for investments in associates and joint ventures.
(b)    Assumptions and estimation uncertainties
Preparation of consolidated financial statements requires assumptions and estimates of the future, and the management requires judgement to apply the Group’s accounting policies. The estimates and assumptions are continuously assessed, considering historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next future financial year are addressed below.
For the period ended October 31, 2021, the spread of Coronavirus disease 2019
(“COVID-19”)
has a material impact on the global economy. It may have a negative impact; such as, decrease in productivity, decrease or delay in sales, collection of existing receivables and others. Accordingly, it may have a negative impact on the financial position and financial performance of the Group.

Notes to the Consolidated Financial Statements
For the period from January 1, 2021 to October 31, 2021 and for the years ended December 31, 2020 and 2019
2.    Basis of Preparation,  continued
Assumptions and estimates applied in the preparation of the consolidated financial statements can be adjusted depending on changes in the uncertainty from
COVID-19.
Also, the ultimate effect of
COVID-19
to the Group’s business, financial position and financial performance cannot presently be determined.
The following are estimates and assumptions about management decisions and significant risks that may affect the adjustment of the carrying amount of assets and liabilities in the following financial years: Additional information on significant judgements and estimates for some items is included in the separate footnotes.
 
(i)
(1)
Fair valueOn January 25, 2024, the Board of financial instruments
Directors of the Parent Company approved the disposal of treasury shares and details of the transaction are as follows:
In principle, the fair value of financial instruments that are not traded in an active market is determined using valuation techniques. The Group is making judgments on the selection and assumptions of various evaluation techniques based on important market conditions as of the end of the reporting period (see note 6).
(ii)
Corporate income tax
There is uncertainty in determining the final tax effect as corporate tax on the Group’s taxable income is calculated by applying various national tax laws and tax authorities’ decisions. The Group recognized the corporate tax effect, which is expected to be borne in the future as a result of business activities until the end of the reporting period, as current tax and deferred tax after the best estimation process. However, the actual future final corporate tax burden may not be consistent with the assets and liabilities recognized, and this difference may affect current and deferred tax assets and liabilities when the final tax effect is confirmed.
The Group will pay additional corporate taxes calculated by the method prescribed by the tax law when a certain amount of taxable income is not used for investment, salary increase, etc. for a certain period of time. Therefore, when measuring current and deferred taxes during the period, the tax effects should be reflected, and the corporate tax to be borne by the Group depends on the level of investment and salary growth in each year, so there is uncertainty in calculating the final tax effect.
In accordance with IAS 12, the Group reviews uncertainty in its tax treatment and reflects the impact of uncertainty in its financial statements if the tax authorities conclude that uncertainty is unlikely to be accepted, using a method that expects better prediction of uncertainty:
Most likely: the single most likely amount within the range of possible outcomes
Expected value: the sum of all amounts in the range of possible outcomes multiplied by each probability
(iii)
Provisions
The Group calculates provisions related to litigation costs as of the end of the reporting period, which are determined by estimates based on past experience (see note 20).
(iv)
Net defined benefit liabilities
The present value of the net defined benefit liability is affected by various factors determined by the actuarial method, especially changes in the discount rate (see note 21).
(v)
Inventories
Estimating the net realizable value of inventories is based on the most reliable evidence available as of the estimated date for the amount feasible from inventories. In addition, if the Group confirms the circumstances in which an event exists at the end of the reporting period, it shall estimate the change in price or cost directly related to the event.

(vi)
Revenue recognition
A refund liability and a right to the returned goods are recognized for the products expected to be returned once they are sold. Accumulated experience is used to estimate such returns at the time of sale at a portfolio level (expected value method), and the Group’s revenue is affected by changes in expected return rate.
Sales of goods are recognized based on considerations specified in the contract, net of sales incentives, when control of the products has transferred. The sales deduction, which affects the Company’s revenue, is reasonably estimated based on historical experience and past contracts.
(vii)
Development cost
The recoverable amounts of development cost have been determined based on
value-in-use
calculations, and those calculations are based on estimates.
(viii)
Depreciation of property, plant, and equipment and Intangible assets
The depreciation method, residual values and useful lives of property, plant and equipment and Intangible assets are reviewed, and adjusted if appropriate, at the end of each reporting period. If the resulting estimates differ from previous estimates, the difference is accounted for as a change in accounting estimates in accordance with IAS 8
‘Accounting Policies, Changes in Accounting Estimates and Errors’
.
(ix)
Goodwill
The recoverable amount of cash-generating units to review goodwill for impairment is determined on the basis of their net fair value.
(x)
Lease
In determining the lease term, the Group considers all relevant facts and circumstances that create an economic incentive to exercise an extension option, or not exercise a termination option. Extension options (or periods after termination options) are only included in the lease term if the lease is reasonably certain to be extended (or not terminated).
For warehouses, retail stores, and equipment leases, the most relevant factors are generally as follows:
If a significant penalty is to be paid to terminate (not to extend), it is generally quite certain that the Group exercises the option to extend (not to extend).
It is generally fairly certain that the Group exercises the option to extend (not exercise the option to terminate) if the lease is expected to have significant residual value.
In other cases than the above, the Group will consider other factors, including the lease duration and costs, and the discontinuation required to replace the leased asset.
Most extension options in office and vehicle transport leases are not included in lease liabilities because the Group can replace the asset without significant cost or business interruption.
The Group reevaluates the lease term if the option is actually exercised (or not exercised) or the Group is liable to exercise (not exercised) the option. Only when significant events occur or there are significant changes in the circumstances that affect the lessee’s control of the lease term, the Group changes its judgment to ensure that the option to extend (or will not be exercised) is significant.

(c) Fair value measurement
The Group establishes fair value measurement policies and procedures as its accounting policies and disclosures require fair value measurements for various financial and
non-financial
assets and liabilities. Such policies and procedures are executed by the valuation department, which is responsible for the review of significant fair value measurements including fair values classified as level 3 in the fair value hierarchy.
The valuation department 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 valuation department assesses the evidence obtained from the third parties to support the conclusion that these valuations meet the requirements of IFRS, including the level in the fair value hierarchy in which the valuations should be classified.
The Group reports significant valuation issues to the audit committee.
When measuring the fair value of an asset or a liability, the Group uses observable market 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 within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices)
Level 3: inputs for the asset or liability that are not based on observable market data (unobservable inputs)
If various inputs used to measure fair value of assets or liabilities fall into different levels of the fair value hierarchy, the Group classifies the assets and liabilities at the lowest level of inputs among the fair value hierarchy, which is significant to the entire measured value. The Group recognizes transfers between levels at the end of the reporting period of which such transfers occurred.
Information about assumptions used for fair value measurements is included in note 6 financial risk management.
3.    Significant Accounting Policies
The significant accounting policies applied by the Group in preparation of its consolidated financial statements are explained below. Except for the new accounting standards that are effective for annual periods beginning on or after January 1, 2021, the accounting policies set out below have been applied consistently to all periods presented in these consolidated financial statements.
(1)    Operating Segments
An operating segment is a component of the Group that: 1) engages in business activities from which it may earn revenues and incur expenses, including revenues and expenses that relate to transactions with other components of the Group, 2) whose operating results are reviewed regularly by the Group’s Chief Operating Decision Maker (“CODM”) in order to allocate resources and assess its performance, and 3) for which discrete financial information is available. The Group’s CODM is the board of directors, who do not receive and therefore do not review discrete financial information for any component of the Group. Accordingly, no operating segment information is included in these consolidated financial statements. Entity wide disclosures of geographic, product and customer information are provided in note 4 and 27.

3.    Significant Accounting Policies,  continued
(2)    Consolidation
(a)    Business combination
A business combination is accounted for by applying the acquisition method, unless it is a combination involving entities or businesses under common control.
The consideration transferred in the acquisition is generally measured at fair value, as are the identifiable net assets acquired. Any goodwill that arises is tested annually for impairment. Any gain on a bargain purchase is recognized in profit or loss immediately. Transaction costs are expensed as incurred and during period of service, except if related to the issue of debt or equity securities according to IAS 32 and IFRS 9.
The consideration transferred does not include amounts related to the settlement of
pre-existing
relationships. Such amounts are generally recognized in profit or loss.
Any contingent consideration is measured at fair value at the date of acquisition. If an obligation to pay contingent consideration that meets the definition of a financial instrument is classified as equity, then it is not remeasured and settlement is accounted for within equity. Otherwise, subsequent changes in the fair value of the contingent consideration are recognized in profit or loss.
If share-based payment awards (replacement awards) are required to be exchanged for awards held by the acquiree’s employees (acquiree’s awards), then all or a portion of the amount of the acquirer’s replacement awards is included in measuring the consideration transferred in the business combination. This determination is based on the market-based measure of the replacement awards compared with the market-based measure of the acquiree’s awards and the extent to which the replacement awards relate to
pre-combination
service.
(b)    Non-controlling
interests
Non-controlling
interests are measured at their proportionate share of the acquiree’s identifiable net assets at the date of acquisition.
Changes in the Group’s interest in a subsidiary that do not result in a loss of control are accounted for as equity transactions.
(c)    Subsidiaries
Subsidiaries are entities controlled by the Group. The Group controls an entity when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the entity. Consolidation of an investee begins from the date the Group obtains control of the investee and cease when the Group loses control of the investee.
(d)    Loss of control
If the Group loses control of a subsidiary, the Group derecognizes the assets and liabilities of the former subsidiary from the consolidated statement of financial position and recognizes gain or loss associated with the loss of control attributable to the former controlling interest. Any investment retained in the former subsidiary is recognized at its fair value when control is lost.
(e)    Interests in equity-accounted investees
The Group’s interest in equity-accounted investees comprise interests in an associate and a joint venture. An associate are these entities in which the Group has significant influence, but not control or joint control, over the

3.    Significant Accounting Policies,  continued
entity’s financial and operating policies. A joint venture is an arrangement in which the Group has joint control, whereby the Group has rights to the net assets of the arrangement, rather than rights to its assets and obligations for its liabilities.
Interests in associates and the joint venture are initially recognized at cost including transaction costs. Subsequent to initial recognition, their carrying amounts are increased or decreased to recognize the Group’s share of the profit or loss and changes in equity of the associate or the joint venture. Distributions from equity-accounted investees are accounted for as deduction from the carrying amounts.
(f)    Transactions eliminated on consolidation
Intra-group balances and transactions, and any unrealized income and expenses arising from intra-group transactions, are eliminated in preparing the consolidated financial statements. The Group’s share of unrealized gain incurred from transactions with equity-accounted investees are eliminated and unrealized loss are eliminated using the same basis if there are no evidence of asset impairments.
(g)    Business combinations under common control
The assets and liabilities acquired in the combination of entities or business under common control are recognized at the carrying amounts recognized previously in the consolidated financial statements of the ultimate parent. The difference between consideration transferred and carrying amounts of net assets acquired is added to or deducted from other capital adjustments.
(3)    Cash and cash equivalents
Cash and cash equivalents comprise cash balances and call deposits with maturities of three months or less from the acquisition date that are subject to an insignificant risk of changes in their fair value, and are used by the Group in the management of its short-term commitments.
(4)    Inventories
The cost of inventories is based on the weighted average method (except for goods
in-transit
that is based on the specific identification method), and includes expenditures incurred in acquiring the inventories, production or conversion costs and other costs incurred in bringing inventories to their existing location and condition. In the case of manufactured inventories and
work-in-process,
cost includes an appropriate share of production overheads based on the actual capacity of production facilities. However, the normal capacity is used for the allocation of fixed production overheads if the actual level of production is lower than the normal capacity.
Inventories are measured at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and selling expenses. The amount of any write-down of inventories to net realizable value and all losses of inventories shall be recognized as an expense in the period the write-down or loss occurs. The amount of any reversal of any write-down of inventories, arising from an increase in net realizable value, shall be recognized as a reduction in the amount of inventories recognized as an expense in the period in which the reversal occurs.
(5)    Non-derivative
financial assets
(a)    Initial recognition and measurement
Trade and other receivables, and debt investment are initially recognized when they are originated. Other financial assets and financial liabilities are recognized when the Group becomes a party to the contractual provisions of the instruments.

For the period from January 1, 2021 to October 31, 2021 and for the years ended December 31, 2020 and 2019
3.    Significant Accounting Policies,  continued
A financial asset and financial liability (unless it is an account receivable—trade without a significant financing component that is initially measured at the transaction price) are initially measured at fair value plus, for an item not at fair value through profit or loss (FVTPL), transaction costs that are directly attributable to its acquisition.
(b)    Classification and subsequent measurements
On initial recognition, a financial asset is classified as measured at: amortized cost; fair value through other comprehensive income (FVOCI)—debt investment; FVOCI—equity investment; or FVTPL. The classification of financial assets is generally based on the business model in which a financial asset is managed and its contractual cash flow characteristics. In case of changing its business model, all affected financial asset are reclassified on the first day of the first reporting period after the change in the business model.
A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as at FVTPL:
it is held within a business model whose objective is to hold assets to collect contractual cash flow; and
its contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding.
A debt investment is measured at FVOCI if it meets both of the following conditions and is not designated as at FVTPL:
it is held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets; and
its contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding.
On initial recognition of an equity investment that is not held for trading, the Group may irrevocably elect to present subsequent changes in the investment’s fair value in other comprehensive income. This election is made on an
investment-by-investment
basis and irrevocable election can be made at initial recognition.
All financial assets not classified as measured at amortized cost or FVOCI as described above are measured at FVTPL. This includes all derivative financial assets. On initial recognition, the Group may irrevocably designate a financial asset that otherwise meets the requirements to be measured at amortized cost or at FVOCI as at FVTPL if doing so eliminates or significantly reduces an accounting mismatch that would otherwise arise.
The Group makes an assessment of the objective of the business model in which, financial assets is held at a portfolio level because this best reflects the way the business is managed and information is provided to management. The information considered includes:
the stated policies and objectives for the portfolio and the operation of those policies in practice;
how the performance of the business model and the financial assets held within that business model are evaluated and reported to the entity’s key management personnel;
the risks that affect the performance of the business model (and the financial assets held within that business model) and, in particular, the way in which those risks are managed;
how managers of the business are compensated (e.g. whether the compensation is based on the fair value of the assets managed or on the contractual cash flows collected); and
the frequency, volume and timing of sales of financial assets in prior periods, the reason for those sales and expectation about future sales activity for financial asset.

3.    Significant Accounting Policies,  continued
Transfers of financial assets to third parties in transactions that do not qualify for derecognition are not considered sales for this purpose, consistent with the Group’s continuing recognition of the assets.
For the purposes of this assessment, ‘principal’ is defined as the fair value of the financial assets on initial recognition. ‘Interest’ is defined as consideration for the time value of money and for the credit risk associated with the principal amount outstanding during a particular period of time and for other basic lending risks and costs (e.g. liquidity risk and administrative costs), as well as a profit margin.
In assessing whether the contractual cash flows are solely payments of principal and interest, the Group considers the contractual terms of the instrument. This includes assessing whether the financial asset contains a contractual term that could change the timing or amount of contractual cash flows such that it would not meet this condition. In making this assessment, the Group considers:
contingent events that would change the amount or timing of cash flows;
terms that may adjust the contractual coupon rate, including variable-rate features;
prepayment and extension features; and
terms that limit the Group’s claim to cash flows from specified assets (e.g.
non-recourse
features).
A prepayment feature is consistent with the solely payments of principal and interest criterion if the prepayment amount substantially represents unpaid amounts of principal and interest on the principal amount outstanding, which may include reasonable additional compensation for early termination of the contract. Additionally, for a financial asset acquired at a discount or premium to its contractual par amount, a feature that permits or requires prepayment at an amount that substantially represents the contractual par amount plus accrued (but unpaid) contractual interest (which may also include reasonable additional compensation for early termination) is treated as consistent with this criterion if the fair value of the prepayment feature is insignificant at initial recognition.
The following accounting policies apply to subsequent measurements of financial assets.
Financial assets at FVTPL
These assets are subsequently measured at fair value. Net gains and losses, including any interest or dividend income, are recognized in profit or loss.
Financial assets at amortized cost
These assets are subsequently measured at amortized cost using the effective interest method. The amortized cost is reduced by impairment losses. Interest income, foreign exchange gains and losses and impairment are recognized in profit or loss. Any gain or loss on derecognition is recognized in profit or loss.
Debt investments at FVOCI
These assets are subsequently measured at fair value. Interest income is calculated using the effective interest method. Foreign exchange gains and losses and impairment are recognized in profit or loss. Other net gains and losses are recognized in OCI. On derecognition, gains and losses accumulated in OCI are reclassified to profit or loss.
Equity investments at FVOCI
These assets are subsequently measured at fair value. Dividends are recognized as income in profit or loss unless the dividend clearly represents a recovery of part of the cost of the investment. Other net gains and losses are recognized in OCI and are never reclassified to profit or loss.

3.    Significant Accounting Policies,  continued
(c)    De-recognition
The Group derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred or in which the Group neither transfers nor retains substantially all of the risks and rewards of ownership and it does not retain control of the financial asset.
The Group enters into transactions whereby it transfers assets recognized in its statement of financial position, but retain either all or substantially all of the risks and rewards of the transferred assets. In these cases, the transferred assets are not derecognized.
(d)    Offsetting between financial assets and financial liabilities
Financial assets and financial liabilities are offset and the net amount is presented in the consolidated statement of financial position only when the Group currently has a legally enforceable right to offset the recognized amounts, and there is the intention to settle on a net basis or to realize the asset and settle the liability simultaneously.
(6)    Derivative financial instruments
Derivatives are initially recognized at fair value. Subsequent to initial recognition, derivatives are measured at fair value at the end of each reporting period, and changes in the fair value of derivatives therein are accounted for as described below.
(a)    Hedge accounting
The Group enters into a
fixed-to-fixed
cross currency swap contract and a
floating-to-fixed
cross currency interest rate swap contract to hedge interest rate risk and currency risk.
On initial designation of the hedge, the Group formally documents the relationship between the hedging instrument(s) and hedged item(s), including the risk management objectives and strategy in undertaking the hedge transaction. In addition, the document includes hedging instruments; hedged items; initial commencement date of those hedge relationship; fair value of hedged items based on hedged risk during the subsequent period; and the method of valuation on hedging instruments offsetting changes in cash flow.
Cash flow hedge
When a derivative is designated to hedge the variability in cash flows attributable to a particular risk associated with a recognized asset or liability, the effective portion of changes in the fair value of the derivative is recognized in other comprehensive income, net of tax, and presented in accumulated other comprehensive income. Any ineffective portion of changes in the fair value of the derivative is recognized immediately in profit or loss. If the hedging instrument no longer meets the criteria for hedge accounting, expires or is sold, terminated, exercised, or the designation is revoked, then hedge accounting is discontinued prospectively. The cumulative gain or loss on the hedging instrument that has been recognized in other comprehensive income is reclassified to profit or loss in the periods which the forecasted transaction occurs.
(b)    Other derivative financial instruments
Other derivative financial instrument not designated as a hedging instrument are measured at fair value, and the changes in fair value of the derivative financial instrument is recognized immediately in profit or loss.

(7)    Impairment of financial assets
(a)    Recognition of impairment on financial assets
The Group recognizes loss allowances for expected credit losses (ECLs) on:
financial assets measured at amortized costs; and
contract assets.
The Group measures impairment losses at an amount equal to lifetime ECLs except for the below assets, which are measured at
12-month
ELCs.
credit risk of debt instruments is low at the end of reporting date
credit risk has not increased significantly since the initial recognition of debt investment (lifetime ECL: ECL that resulted from all possible default events over the expected life of a financial instrument)
The Group adopted an accounting policy to recognize loss allowances at an amount equal to lifetime expected credit losses for trade receivables and contract assets.
In assessing whether the credit risk on a financial instrument has increased significantly since initial recognition and estimating expected credit loss, the Group considers both quantitative and qualitative information that is reasonable and supportable, including historical experience and forward-looking information that is available without undue cost or effort.
Lifetime expected credit losses are the expected credit losses that result from all possible default events over the expected life of a financial instrument.
12-month
ECLs are the portion of ECLs that result from all default events that are possible within the 12 months after the reporting date (or a shorter period if the expected life of the instrument is less than 12 months).
The maximum period considered when estimating ECLs is the maximum contractual period over which the Group is exposed to credit risk.
(b)    Measurement of expected credit loss
ECLs are a probability-weighted estimate of credit losses. Credit losses are measured as the present value of all cash shortfalls (i.e. the difference between the cash flows due to the entity in accordance with the contract and the cash flows that the Group expects to receive). ECLs are discounted at the effective interest rate of the financial instrument.
(c)    Credit-impaired financial instrument
A debt instrument carried at amortized cost and fair value through other comprehensive income (FVOCI) is assessed at the end of each reporting period to determine whether there is objective evidence that it is impaired. A financial asset is credit- impaired when one or more events that have a detrimental impact on the estimated future cash flows of that asset have occurred.
Objective evidence that a financial asset is impaired includes:
significant financial difficulty of the issuer or borrower;
a breach of contract, such as default or delinquency in interest or principal payments;

the Group, for economic or legal reasons relating to the borrower’s financial difficulty, granting to the borrower a concession that the Group would not otherwise consider;
it becoming probable that the borrower will enter bankruptcy or other financial reorganization; or
the disappearance of an active market for the financial asset because of financial difficulties
(d)  �� Presentation of credit loss allowance on financial position
Loss allowances for financial assets measured at amortized cost are deducted from the gross carrying amount of the assets.
(e)    Write-off
The Group writes off a financial asset when it has no reasonable expectations of recovering the contractual cash flows on a financial asset in its entirety or a portion thereof. For corporate customers, the Group individually makes an assessment with respect to the timing and amount of
write-off
based on whether there is a reasonable expectation of recovery. However financial assets that are written off could still be subject to collection activities according to the Group’s past due collection process.
(8)    Property, plant and equipment
Property, plant and equipment are initially measured at cost. The cost of property, plant and equipment includes expenditures arising directly from the construction or acquisition of the asset, any costs directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management and the initial estimate of the costs of dismantling and removing the item and restoring the site on which it is located.
Subsequent to initial recognition, an item of property, plant and equipment is carried at its cost less any accumulated depreciation and any accumulated impairment losses.
Subsequent costs are recognized in the carrying amount of property, plant and equipment at cost or, if appropriate, as separate items if it is probable that future economic benefits associated with the cost will flow to the Group and it can be measured reliably. The carrying amount of the replaced part is derecognized. The costs of the
day-to-day
repair and maintenance are recognized in profit or loss as incurred.
Property, plant and equipment, except for land, are depreciated on a straight-line basis over estimated useful lives that appropriately reflect the pattern in which the asset’s future economic benefits are expected to be consumed.
Gains and losses on disposal of an item of property, plant and equipment are determined by comparing the proceeds from disposal with the carrying amount of property, plant and equipment and are recognized as other income or expenses.
The estimated useful lives of the Group’s property, plant and equipment are as follows:

3.    Significant Accounting Policies,  continued
Depreciation methods, useful lives, and residual values are reviewed at the end of each reporting period and, if appropriate, accounted for as changes in accounting estimates.
(9)    Borrowing costs
The Group capitalizes borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset as part of the cost of that asset. Other borrowing costs are recognized in expense as incurred. A qualifying asset is an asset that requires a substantial period of time to get ready for its intended use or sale.
Financial assets and inventories that are manufactured or otherwise produced over a short period of time are not qualifying assets. Assets that are ready for their intended use or sale when acquired are not qualifying assets.
To the extent that the Group borrows funds specifically for the purpose of obtaining a qualifying asset, the Group determines the amount of borrowing costs eligible for capitalization as the actual borrowing costs incurred on that borrowing during the period less any investment income on the temporary investment of those borrowings. To the extent that the Group borrows funds generally and uses them for the purpose of obtaining a qualifying asset, the Group determines the amount of borrowing costs eligible for capitalization by applying a capitalization rate to the expenditures on that asset. The capitalization rate is the weighted average of the borrowing costs applicable to the borrowings of the Group that are outstanding during the period, other than borrowings made specifically for the purpose of obtaining a qualifying asset. The amount of borrowing costs that the Group capitalizes during a period does not exceed the amount of borrowing costs incurred during that period.
(10)    Intangible assets
Intangible assets are measured initially at cost and, subsequently, are carried at cost less accumulated amortization and accumulated impairment losses.
Goodwill arising from business combinations is recognized as the excess of the consideration transferred in the acquisition over the net fairAggregate disposal value of the identifiable assets acquired and liabilities assumed. Any deficit is a bargain purchase that is recognized in profit or loss. Goodwill is measured at cost less accumulated impairment losses.
Amortization of intangible assets is calculated on a straight-line basis over the estimated useful lives of intangible assets from the date that they are available for use. The residual value of intangible assets is zero. However, certain intangible assets are determined as having indefinite useful lives and not amortized as there is no foreseeable limit to the period over which the assets are expected to be available for use.
The estimated useful lives of the Group’s intangible assets are as follows:
  
Useful lives (years)W
24,707 million

Method of disposal
  4 - 20Over-the-counter

Other intangible assets include royalty payments with useful lives of 4 to 20 years.
Useful lives and the amortization methods for intangible assets with finite useful lives are reviewed at the end of each reporting period. The useful lives of intangible assets that are not being amortized are reviewed at the end of each reporting period to determine whether events and circumstances continue to support indefinite useful life assessments for those assets. Changes are accounted for as changes in accounting estimates.
Expenditures on research activities, undertaken with the prospect of gaining new scientific or technical knowledge and understanding, are recognized in profit or loss as incurred. Development expenditures are

capitalized only if development costs can be measured reliably, the product or process is technically and commercially feasible, future economic benefits are probable, and the Group intends to and has sufficient resources to complete development and to use or sell the asset. Other development expenditures are recognized in profit or loss as incurred.
Subsequent expenditures are capitalized only when they increase the future economic benefits embodied in the specific asset to which it relates. All other expenditures, including expenditures on internally generated goodwill and others, are recognized in profit or loss as incurred.
(11)    Government grants
Government grants are not recognized unless there is reasonable assurance that the Group will comply with the grant’s conditions and that the grant will be received.
(a)    Grants related to assets
Government grants whose primary condition is that the Group purchases, constructs or otherwise acquires
non-current
assets are deducted in calculating the carrying amount of the asset. The grant is recognized in profit or loss over the useful lives of depreciable assets.
(b)    Grants related to income
Government grants which are intended to compensate the Group for expenses incurred are recognized in profit or loss by as deduction of the related expenses.
(12)    Investment property
Property held for the purpose of earning rental income or benefiting from capital appreciation is classified as investment property. Investment property is initially measured at its cost. Transaction costs are included in the initial measurement. Subsequently, investment property is carried at cost less accumulated depreciation and impairment losses.
Subsequent costs are recognized in the carrying amount of investment property at cost or, if appropriate, as separate items if it is probable that future economic benefits associated with the cost will flow to the Group and it can be measured reliably. The carrying amount of the replaced part is derecognized. The costs of the
day-to-day
repair and maintenance are recognized in profit or loss as incurred.
Investment property is depreciated on a straight-line basis over 40 years.
Depreciation methods, useful lives and residual values are reviewed at the end of each reporting period and, if appropriate, accounted for as changes in accounting estimates.
(13)    Impairment of
non-financial
assets
The carrying amounts of the Group’s
non-financial
assets, other than assets arising from employee benefits, inventories, and deferred tax assets, are reviewed at the end of the reporting period to determine whether there is any indication of impairment. If any such indication exists, then the asset’s recoverable amount is estimated. Goodwill and intangible assets that have indefinite useful lives or that are not yet available for use, irrespective of whether there is any indication of impairment, are tested for impairment annually by comparing their recoverable amount to their carrying amount.
The Group estimates the recoverable amount of an individual asset; however if it is impossible to measure the individual recoverable amount of an asset, the Group estimates the recoverable amount of cash-generating unit

(“CGU”). A CGU is the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets. The recoverable amount of an asset or CGU is the greater of its value in use and its fair value less costs to sell.
The value in use is estimated by applying a
pre-tax
discount rate that reflects current market assessments of the time value of money and the risks specific to the asset or CGU for which estimated future cash flows have not been adjusted, to the estimated future cash flows expected to be generated by the asset or CGU.
An impairment loss is recognized if the carrying amount of an asset or a CGU exceeds its recoverable amount.
Goodwill acquired in a business combination is allocated to each CGU that is expected to benefit from the synergies arising from business combination. Any impairment identified at the CGU level will first reduce the carrying value of goodwill and then be used to reduce the carrying amount of the other assets in the CGU on a pro rata basis.
Except for impairment losses in respect of goodwill, which are never reversed, an impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount. An impairment loss is reversed only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized.
(14)    Leases
The Group assesses whether a contract is or contains a lease at inception of a contract. Under IFRS 16, a contract is, or contains, a lease if the contract conveys a right to control the use of an identified asset for a period of time in exchange for consideration.
(a)    As a lessee
The Group recognizes for a
right-of-use
asset and a lease liability at the lease commencement date. The
right-of-use
asset is initially measured at cost, the initial amount of the lease liability, adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred and an estimate of costs to dismantle and remove of the underlying asset, or to restore the underlying asset or the site on which the underlying asset is located, less any lease incentives received.
The
right-of-use
asset is subsequently depreciated using the straight-line method from the commencement date to the end of the lease term. In case that ownership of the
right-of-use
asset is transferred at the end of the lease term, or the cost of the
right-of-use
asset includes the exercise price of a purchase option, the
right-of-use
asset will be depreciated over the useful life of the underlying asset, which is determined on the same basis as those of property and equipment. In addition, the
right-of-use
asset may be reduced by an impairment loss or adjusted for remeasurements of the lease liability.
The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Group’s incremental borrowing rate. The Group generally uses its incremental borrowing rate as the discount rate.
Lease payments included in the measurement of the lease liability consist of the following:
fixed payments (including
in-substance
fixed payments)

3.     Significant Accounting Policies,  continued
variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the commencement date
amounts expected to be payable under a residual value guarantee
the exercise price under a purchase option that the Group is reasonably certain to exercise
lease payments in an optional renewal period, if the Group is reasonably certain to exercise extension option, and penalties for early termination of a lease unless the Group is reasonably certain not to terminate early.
The lease liability is subsequently increased by the interest expense recognized for the lease liability and decreased by reflecting the payment of the lease. The lease liability is remeasured when there is a change in future lease payments arising from changes in an index or a rate (interest rate), if there’s a change in the Group’s estimate of the amount expected to be paid under a residual value guarantee, or if the Group changes in the assessment of whether the option to buy or extend is reasonably certain to be exercised or not to exercise the termination option.
When the lease liabilities are remeasured, a corresponding adjustment is made to the carrying amount of the
right-of-use
asset, or is recorded in profit or loss if the carrying amount of the
right-of-use
asset has been reduced to zero.
A lessee shall remeasure the lease liability as an adjustment to the
right-of-use
asset, if either:
a change in the lease term or a change in circumstances or significant events that result in a change in the assessment of the exercise of the purchase option. In such cases, the lease liability is remeasured by discounting the modified lease payment at the revised discount rate;
the lease payment changes due to changes in the index or rate (interest rate) or the amount expected to be paid according to the residual value guarantee. In such cases, the lease liability measures the modified lease fee again by discounting it at an unchanged discount rate. However, if a change in the variable interest rate causes a change in the lease payments, the revised discount rate that reflects the change in interest rates is used; or
the lease agreement changes and is not accounted for as a separate lease. In such cases, the lease liability is remeasured by discounting the modified lease payment at the revised discount rate as of the effective date of the lease change, based on the lease term of the modified lease.
The Group has elected not to recognize
right-of-use
assets and lease liabilities for some leases of
low-value
assets and short-term leases. The Group recognizes the lease payments associated with these leases as an expense on a straight-line basis over the lease term.
At inception or on reassessment of a contract that contains a lease component, the Group allocates the consideration in the contract to each lease and
non-lease
component on the basis of their relative stand-alone prices. However, for certain agreements, the Group has elected practical expedient not to separate
non-lease
components and account for the lease and
non-lease
components as a single lease component.
The Group separately presents
right-of-use
assets that do not meet the definition of investment property in the statement of financial position.
Subsequently, the right-of-use asset is accounted for consistently with the accounting policies applicable to the asset.
(b)    As a lessor
As a lessor, the Group determines whether the lease is a finance lease or an operating lease at the inception of the lease.

For the period from January 1, 2021 to October 31, 2021 and for the years ended December 31, 2020 and 2019
3.    Significant Accounting Policies,  continued
To classify each lease, the Group generally determines whether the lease transfers most of the risks and rewards of ownership of the underlying asset. If most of the risks and rewards of ownership of the underlying asset are transferred to the lessee, the lease is classified as a finance lease, otherwise the lease is classified as an operating lease. As part of this assessment, the Group considers whether the lease term represents a significant portion of the economic life of the underlying asset.
When the Group is an intermediate lessor, it accounts for its interests in the head lease and the sublease separately. In addition, the classification of a lease is determined by the
right-of-use
asset arising from the head lease, not the underlying asset. If a head lease is a short-term lease to which the Group applies the recognition exemption, then the sub-lease is classified as an operating lease.
The Group has applied IFRS 15
‘Revenue from Contracts with Customers’
to allocate consideration in the contract to each lease and
non-lease
components.
The Group recognizes the lease payments received from operating leases on a straight-line basis over the lease term as revenue in ‘other revenue’.
The accounting policies that the Group has applied to the comparative period as lessors are not different from those in IFRS 16.
(15)    Non-derivative
financial liabilities
The Group classifies
non-derivative
financial liabilities into financial liabilities at fair value through profit or loss or other financial liabilities in accordance with the substance of the contractual arrangement and the definitions of financial liabilities. The Group recognizes financial liabilities in the consolidated statement of financial position when the Group becomes a party to the contractual provisions of the financial liability.
(a)    Financial liabilities at fair value through profit or loss
Financial liabilities at fair value through profit or loss include financial liabilities held for trading or designated as such upon initial recognition. Subsequent to initial recognition, financial liabilities at fair value through profit or loss are measured at fair value, and changes therein are recognized in profit or loss. Upon initial recognition, any directly attributable transaction costs are recognized in profit or loss as incurred.
(b)    Other financial liabilities
Non-derivative
financial liabilities other than financial liabilities at fair value through profit or loss are classified as other financial liabilities. At the date of initial recognition, other financial liabilities are measured at fair value less any directly attributable transaction costs. Subsequent to initial recognition, other financial liabilities are measured at amortized cost using the effective interest rate method.
(c)    Derecognition of financial liability
The Group derecognizes financial liability when its contractual obligations are discharged, cancelled or expire. The Group also derecognizes a financial liability, when its terms are modified and the cash flows of the modified liability are substantially different, in which case a new financial liability based on the modified terms is recognized at fair value. On derecognition of a financial liability, the difference between the carrying amount extinguished and the consideration paid (including any
non-cash
assets transferred of liabilities assumed) is recognized in profit or loss.

(16)    Employee benefits
(a)    Short-term employee benefits
Short-term employee benefits are employee benefits that are due to be settled within 12 months after the end of the reporting period in which the employees render the related service. When an employee has rendered service to the Group during an accounting period, the Group recognizes the undiscounted amount of short-term employee benefits expected to be paid in exchange for that service.
(b)    Other long-term employee benefits
Other long-term employee benefits include employee benefits that are settled beyond 12 months after the end of the reporting period in which the employees render the related service, and are calculated at the present value of the amount of future benefit that employees have earned in return for their service in the current and prior periods. Remeasurements are recognized in profit or loss in the period in which they arise.
(c)    Retirement benefits: defined benefit plans
As of the end of reporting period, defined benefits liabilities relating to defined benefit plans are recognized as present value of defined benefit obligations, net of fair value of plan assets.
The calculation is performed annually by an independent actuary using the projected unit credit method. When the fair value of plan assets exceeds the present value of the defined benefit obligation, the Group recognizes an asset, to the extent of the present value of any economic benefits available in the form of refunds from the plan or reduction in the future contributions to the plan.
Remeasurements of the net defined benefit liability (asset) comprise of actuarial gains and losses, the return on plan assets excluding amounts included in net interest on the net defined benefit liability (asset), and any change in the effect of the asset ceiling, excluding amounts included in net interest on the net defined benefit liability (asset), and are recognized in other comprehensive income. The Group determines net interests on net defined benefit liability (asset) by multiplying discount rate determined at the beginning of the annual reporting period and considers changes in net defined benefit liability (asset) from contributions and benefit payments. Net interest costs and other costs relating to the defined benefit plan are recognized through profit or loss.
When the benefits of a plan are changed or when a plan is curtailed, the resulting change in benefit that relates to past service or the gain or loss on curtailment is recognized immediately in profit or loss. The Group recognizes gains or losses on a settlement of defined benefit plan when the settlement occurs.
(d)    Retirement benefits: defined contribution plans
When an employee has provided service for a certain period of time in relation to the defined contribution plan, the contribution to the defined contribution plan is recognized in profit or loss except to be included in the cost of the asset. The contributions to be paid are recognized as liabilities (accrued expenses) less the contributions that have been already paid.
(e)    Termination benefits
The Group recognizes a liability and expense for termination benefits at the earlier of the period when the Group can no longer withdraw the offer of those benefits and the period when the Group recognizes costs for a restructuring. If benefits are not payable within 12 months after the end of the reporting period, then they are discounted to their present value.

(17)    Provisions
Provisions are recognized when the Group has a present legal or constructive obligation as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation.
The risks and uncertainties that inevitably surround many events and circumstances are taken into account in reaching the best estimate of a provision. Where the effect of the time value of money is material, provisions are determined at the present value of the expected future cash flows.
Where some or all of the expenditures required to settle a provision are expected to be reimbursed by another party, the reimbursement is recognized when, and only when, it is virtually certain that reimbursement will be received if the Group settles the obligation. The reimbursement is treated as a separate asset.
Provisions are reviewed at the end of each reporting period and adjusted to reflect the current best estimates. If it is no longer probable that an outflow of resources embodying economic benefits will be required to settle the obligation, the provision is reversed.
A provision is used only for expenditures for which the provision was originally recognized.
(18)    Emissions Rights
The Group accounts for greenhouse gases emission right and the relevant liability as below pursuant to the
Act on Allocation and Trading of Greenhouse Gas Emission
in Korea.
(a)    Greenhouse Gases Emission Right
Greenhouse Gases Emission Right consists of emission allowances, which are allocated from the government free of charge or purchased from the market. The cost includes any directly attributable costs incurred during the normal course of business.
Emission rights held for the purpose of performing the obligation are classified as intangible asset and are initially measured at cost and after initial recognition are carried at cost less accumulated impairment losses. Emission rights held for short-swing profits are classified as current asset and are measured at fair value with any changes in fair value recognized as profit or loss in the respective reporting period.
The Group derecognizes an emission right asset when the emission allowance is unusable, disposed or submitted to government in which the future economic benefits are no longer expected to be probable.
(b)    Emission liability
Emission liability is a present obligation of submitting emission rights to the government with regard to emission of greenhouse gas. Emission liability is recognized when it is probable that outflows of resources will be required to settle the obligation and the costs required to perform the obligation are reliably estimable. Emission liability is an amount of estimated obligations for emission rights to be submitted to the government for the performing period. The emission liability is measured based on the expected quantity of emission for the performing period in excess of emission allowance in possession and the unit price for such emission rights in the market at the end of the reporting period.
(19)    Foreign currencies
(a)    Foreign currency transactions
Transactions in foreign currencies are translated to the respective functional currencies of Group entities at exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are

3.    Significant Accounting Policies,  continued
retranslated to the functional currency at the exchange rate at the reporting data.
Non-monetary
assets and liabilities denominated in foreign currencies that are measured at fair value are translated to the functional currency at the exchange rate at the date that the fair value was determined.
Foreign currency differences arising on the settlement or retranslation of monetary items are recognized in profit or loss, except for differences arising on the retranslation of the net investment in a foreign operation, which are recognized in other comprehensive income. When a gain or loss on a
non-monetary
item is recognized in other comprehensive income, any exchange component of that gain or loss is recognized in other comprehensive income. Conversely, when a gain or loss on a
non-monetary
item is recognized in profit or loss, any exchange component of that gain or loss is recognized in profit or loss.
(b)    Foreign operations
If the presentation currency of the Group is different from a foreign operation’s functional currency, the financial statements of the foreign operation are translated into the presentation currency using the following methods:
The assets and liabilities of foreign operations, whose functional currency is not the currency of a hyperinflationary economy, are translated to presentation currency at exchange rates at the end of reporting period. The income and expenses of foreign operations are translated to functional currency at everage rates. Foreign currency differences are recognized in other comprehensive income.
Any goodwill arising on the acquisition of a foreign operation and any fair value adjustments to the carrying amounts of assets and liabilities arising on the acquisition of that foreign operation is treated as assets and liabilities of the foreign operation. Thus, they are expressed in the functional currency of the foreign operation and translated at the exchange rates at the end of reporting date.
When a foreign operation is disposed of, the relevant amount in the translation is transferred to profit or loss as part of the profit or loss on disposal. On the partial disposal of a subsidiary that includes a foreign operation, the relevant proportion of such cumulative amount is reattributed to
non-controlling
interest. In any other partial disposal of a foreign operation, the relevant proportion is reclassified to profit or loss.
(20)    Equity capital
Ordinary shares are classified as equity. Incremental costs directly attributable to the issuance of ordinary shares is recognized as a deduction from equity, net of any tax effects.
When the Group repurchases its share capital, the amount of the consideration paid is recognized as a deduction from equity and classified as treasury shares. The profits or losses from the purchase, disposal, reissue, or retirement of treasury shares are not recognized as current profit or loss but recognized directly in equity. If the Group acquires and disposes treasury shares, the consideration paid or received is directly recognized in equity.
(21)    Share-based payment
The Group has granted shares or share options to its employees. For equity-settled share-based payment transactions, the Group measures the goods or services received, and the corresponding increase in equity as a capital adjustment at the fair value of the goods or services received, unless that fair value cannot be estimated reliably. If the Group cannot reliably estimate the fair value of the goods or services received, the Group measures their value, and the corresponding increase in equity, indirectly, by reference to the fair value of the equity instruments granted. If the fair value of the equity instruments cannot be estimated reliably at the measurement date, the Group measures them at their intrinsic value and recognizes the goods or services received based on the number of equity instruments that ultimately vest.

3.    Significant Accounting Policies,  continued
For cash-settled share-based payment transactions, the Group measures the goods or services acquired and the liability incurred at the fair value of the liability. Until the liability is settled, the Group remeasures the fair value of the liability at each reporting date and at the date of settlement, with changes in fair value recognized in profit or loss for the period.
The Group accounts for share-based payment, with options to choose either cash-settled or equity-settled share-based payment, in accordance with the substance of transactions.
(22)    Revenue from contracts with customers
The Group’s accounting policies relating to revenue from contracts with customers are described in note 27.
(23)    Finance income and finance expenses
The Group’s finance income and finance expenses include:
Interest income;
Interest expense;
Dividend income;
The net gain or loss on financial assets at fair value through profit or loss;
Gain or loss on foreign exchange (currency) translation for financial asset and liabilities;
Impairment losses and reversals on investment in debt securities carried at amortized cost method; and
The gain on the remeasurement to fair value of any
pre-existing
interest in an acquire in a business combination
The Group uses effective interest rate method for recognizing interest income and expense. Dividend income is recognized in profit or loss on the date that the Group’s right to receive dividend is established.
The ‘effective interest rate’ is the rate that exactly discounts estimated future cash payments or receipts through the expected life of the financial instrument to:
The gross carrying amount of the financial asset; or
The amortized cost of the financial liability
In calculating interest income and expense, the effective interest rate is applied to the gross carrying amount of the asset (when the asset is not credit-impaired) or to the amortized cost of the liability. However, for financial assets that have become credit-impaired subsequent to initial recognition, interest income is calculated by applying the effective interest rate to the amortized cost of the financial asset. If the asset is no longer credit-impaired, then the calculation of interest income reverts to the gross basis.
(24)    Income taxes
Income tax expense comprises current and deferred tax. Current and deferred tax are recognized in profit or loss except to the extent that it relates to a business combination, or items recognized directly in equity or in other comprehensive income.
(a)    Current tax
Current tax is the expected tax payable or refundable on the taxable income or loss for the year, using tax rates enacted or substantively enacted at the end of the reporting period and any adjustment to tax payable in respect of

previous years. The amount of current tax payable or receivable is the best estimate of tax amount expected to be paid or received that reflects uncertainty related to income taxes. The taxable income is different from the accounting profit for the period since the taxable profit is calculated excluding the temporary differences, which will be taxable or deductible in determining taxable profit (tax loss) of future periods, and
non-taxable
or
non-deductible
items from the accounting profit. The tax expense is calculated on the basis of the tax laws enacted or substantively enacted at the end of the reporting period.
In accordance with
K-IFRS
No.1012, the Group reviews uncertainty in its tax treatment and reflects the impact of uncertainty in its financial statements if the tax authorities conclude that uncertainty is unlikely to be accepted, using a method that expects better prediction of uncertainty:
 (i)(2)
Most likely: the single most likely amount within the range of possible outcomes
(ii)
Expected value: the sum of all amounts in the range of possible outcomes multiplied by each probability.
(b)    Deferred tax
Deferred tax is recognized, using the asset-liability method, in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes.
The Group recognizes a deferred tax liability for all taxable temporary differences associated with investments in subsidiaries, associates and interests in joint ventures except to the extent that the Group is able to control the timing of the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. The Group recognizes deferred tax assets for all deductible temporary differences including unused tax loss and tax credit to the extent that it is probable that the temporary difference will reverse in the foreseeable future and taxable profit will be available against which the temporary difference can be utilized.
The carrying amount of a deferred tax asset is reviewed at the end of each reporting period and reduces the carrying amount to the extent that it is no longer probable that sufficient taxable profit will be available to allow the benefit of part or all of that deferred tax asset to be utilized.
Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period.
The measurement of deferred tax liabilities and deferred tax assets reflects the tax consequences that would follow from the manner in which the Group expects, at the end of the reporting period to recover or settle the carrying amount of its assets and liabilities.
Deferred tax assets and liabilities are offset only if there is a legally enforceable right to offset the related current tax liabilities and assets, and they relate to income taxes levied by the same tax authority and they intend to settle current tax liabilities and assets on a net basis. If there are any additional income tax expense incurred in accordance with dividend payments, such income tax expense is recognized when liabilities relating to the dividend payments are recognized.
(25)    Earnings per share
The Group presents basic and diluted earnings per share (EPS) data for its ordinary shares. Basic EPS is calculated by dividing the profit or loss attributable to ordinary shareholders of the Parent Company by the weighted average number of ordinary shares outstanding during the period, adjusted for own shares held. Diluted EPS is determined by adjusting the profit or loss attributable to ordinary shareholders and the weighted average number of

(26)    New and amended standards adopted by the Group
The following new standards and amendments to standards are effective for accounting periods beginning on or after January 1, 2021 and earlier application is permitted. The impacts on the consolidated financial statements in adopting the following new standards are not expected to be significant.
(a)    Amendments to IFRS 1116 ‘Lease’ — Practical expedient for
COVID-19-Related
Rent Concessions
As a practical expedient, a lessee may elect not to assess whether a rent concession occurring as a direct consequence of the
COVID-19
pandemic is a lease modification. A lessee that makes this election shall account for any change in lease payments resulting from the rent concession the same way it would account for the change applying this standard if the change were not a lease modification. The amendment does not have a significant impact on the consolidated financial statements.
(b)    Amendments to IFRS 1109 ‘Financial Instruments’, IAS 39 ‘Financial Instruments: Recognition and Measurement’ and IFRS 1107 ‘Financial Instruments: Disclosure’, IFRS 1104 ‘Insurance Contracts’, IFRS 1116 ‘Lease’ — Interest Rate Benchmark Reform (Phase 2 amendments)
In relation to interest rate benchmark reform, the amendments provide exceptions including adjust effective interest rate instead of book amounts when interest rate benchmark of financial instruments at amortized costs is replaced, and apply hedge accounting without discontinuance although the interest rate benchmark is replaced in hedging relationship. The amendments do not have a significant impact on the consolidated financial statements.
(27)    New and amended standards not yet adopted by the Group
The following new accounting standards and interpretations that have been published that are not mandatory for October 31, 2021 reporting period and have not been early adopted by the Group.

COVID-19-Related
Rent, Concessions beyond June 30, 2021
The application of the practical expedient, a lessee may elect not to assess whether a rent concession occurring as a direct consequence of the
COVID-19
pandemic is a lease modification, is extended to lease payments originally due on or before September 30, 2022. A lessee shall apply the practical expedient consistently to eligible contracts with similar characteristics and in similar circumstances. The amendment should be applied for annual periods beginning on or after April 1, 2021, and earlier application is permitted. The Group does not expect that these amendments have a significant impact on the consolidated financial statements
(b)    Amendments to IFRS 1103 ‘Business Combination’ — Quotation of Conceptual Framework
The amendments update a reference of definition of assets and liabilities qualify for recognition in revised Conceptual Framework for Financial Reporting. However, the amendments add an exception for the recognition of liabilities and contingent liabilities within the scope of Korea IFRS 1037 Provisions, Contingent Liabilities and Contingent Assets, and IFRIC 2121 Levies. The amendments also confirm that contingent assets should not be recognized at the acquisition date. The amendments should be applied for annual periods beginning on or after January 1, 2022, and earlier application is permitted. The Group does not expect that these amendments have a significant impact on the consolidated financial statements.

(f)    Amendments to IAS 1 ‘Presentation of Financial Statements’— Classification of Liabilities as Current or
Non-current
The amendments clarify that liabilities are classified as either current or
non-current,
depending on the substantive rights that exist at the end of the reporting period. Classification is unaffected by the likelihood that an entity will exercise right to defer settlement of the liability or the expectations of management. Also, the settlement of liability include the transfer of the entity’s own equity instruments, however, it would be excluded if an option to settle them by the entity’s own equity instruments if compound financial instruments is met the definition of equity instruments and recognized separately from the liability. The amendments should be applied for annual periods beginning on or after January 1, 2023, and earlier application is permitted. The Group is reviewing the impact of the amendments on the consolidated financial statements.

6.    Financial Risk Management
(1)    Financial risk management
The Group’s activities are exposed to a variety of financial risks: market risk (including foreign exchange risk, interest rate risk and price risk), credit risk and liquidity risk. The Group’s overall risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the Group’s financial performance.
Risk management is carried out by the Parent Company’s corporate finance division in accordance with policies approved by the board of directors. The Parent Company’s corporate finance division identifies, evaluates and hedges financial risks in close cooperation with the Group’s operating units. The board of directors provides written principles for overall risk management, as well as written policies covering specific areas, such as foreign exchange risk, interest rate risk, and credit risk, use of derivative financial instruments and
non-derivative
financial instruments, and investment of excess liquidity.
(a)    Market risk
(i)    Foreign currency risk
The Group operates internationally and is exposed to foreign currency risk arising from various currency exposures, primarily with respect to US dollar, Chinese Yuan, Euro and Japanese Yen. Foreign currency risk arises

Also, as described in note 23, the Group entered into a
fixed-to-fixed
cross currency swap and a
floating-to-fixed
cross currency interest rate swap to hedge foreign currency rate risk relating to bonds and borrowings denominated in foreign currencies.
As of October 31, 2021, effects on profit before income tax as a result of strengthening or weakening of the foreign currencies by 10% are as follows:

(ii)    Interest rate risk
Interest rate risk of the Group is defined as the risk that the interest expenses arising from borrowings will fluctuate because of changes in future market interest rate. The interest rate risk mainly arises through floating rate borrowings, and is partially offset by interests received from floating rate financial assets.
The Group is managing cash flow interest rate risk using
floating-to-fixed
cross currency interest rate swaps. These interest rate swaps have an economic effect of converting floating interest borrowings into fixed interest borrowings. Generally, the Group borrows at a floating interest rate and then swaps at a fixed rate. Under the swap agreement, the Group will settle the difference between fixed interest costs and the floating interest costs calculated according to the principal agreed upon for each counterparty and specific period (mainly quarterly).
The Group is partially exposed to the risk of changing net interest costs due to changes in interest rates as of October 31, 2021. The Group has signed a currency interest rate swap contract on floating interest rate borrowings of ₩585,850 million and interest rate swap contract on floating interest rate borrowings of ₩117,170 million. Therefore, the changes in interest costs subject to fluctuation of interest rates do not have an impact on the profit before income tax for the
ten-month
period ended October 31, 2021.
As of October 31, 2021, if interest rates on borrowings and financial assets had been 100 basis points higher/lower with all other variables held constant, profit before income tax would have been ₩36,389 million (2020 : ₩50,270 million) lower/higher, mainly as a result of higher/lower interest expense on floating rate borrowings and net interest costs on floating rate financial assets.

(iii)    Price risk
The Group invests in equity and debt securities resulted from its business needs and the purpose of liquidity management. The Group’s equity and debt securities are exposed to price risk as of October 31, 2021.
Equity investments that the Group owns are all unlisted equities and the effect of the equity investments on the Group’s profit for the
ten-month
period and other comprehensive income are explained in note 12.
(b)    Credit risk
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, and arises mainly from operating and investing activities. In order to manage credit risk, the Group periodically evaluates the credit worthiness of each customer or counterparty through the analysis of its financial information, historical transaction records and other factors, based on which the Group establishes credit limits for each customer or counterparty.
(i)    Trade and other receivables
For each new customer, the Group individually analyzes its credit worthiness before standard payment and delivery terms and conditions are offered. In addition, the Group is consistently managing trade and other receivables by reevaluating the overseas customer’s credit worthiness and securing collaterals in order to limit its credit risk exposure.
The Group reviews at the end of each reporting period whether trade and other receivables are impaired and maintains credit insurance policies to manage credit risk exposure from oversea customers. The maximum exposure to credit risk as of October 31, 2021 is the carrying amount of trade and other receivables.
(ii)    Other financial assets
Credit risk also arises from other financial assets such as cash and cash equivalents, short-term financial instruments, and deposits with banks and financial institutions as well as short-term and long-term loans mainly due to the bankruptcy of each counterparty to those financial assets. The maximum exposure to credit risk as of October 31, 2021 is the carrying amount of those financial assets. The Group transacts only with banks and financial institutions with high credit ratings, and accordingly management does not expect any significant losses from
non-performance
by these counterparties.
(c)    Liquidity risk
Liquidity risk is the risk that the Group will encounter difficulty in having sufficient funds needed to meet obligations associated with its financial contracts until maturity. The Group forecasts its cash flow and liquidity status and sets action plans on a regular basis to manage liquidity risk proactively.
The Group invests surplus cash in interest-bearing current accounts, time deposits, and demand deposits, choosing instruments with appropriate maturities or sufficient liquidity based on the above-mentioned forecasts.

Long-term investments measured at Level 3 in the fair value hierarchy include investments in special purpose companies of BCPE Pangea Intermediate Holdings Cayman, L.P. (“SPC1”) amounting to ₩3,823,456 million and BCPE Pangea Cayman2 Limited (“SPC2”) amounting to ₩2,521,342 million in connection with the Group’s investments in acquisition of KIOXIA Holdings Corporation (“KIOXIA”, formerly Toshiba Memory Corporation) (see note 12). The fair value of the long-term investments is measured based on the equity value of the underlying asset, KIOXIA estimated utilizing present value discount model.
The fair value of equity investment in SPC1 is measured using an option pricing model allocating the estimated fair value of KIOXIA equity between investors based on distribution priority pursuant to the underlying investment arrangement together with consideration of expected KIOXIA initial public offering and SPC1 liquidation.
The fair value of debt investment in SPC2 convertible bonds is measured based on the estimated KIOXIA’s equity value and SPC2’s equity ownership in KIOXIA (15.0%).

    Risk free rate  -0.10
SPC2 convertible bonds
   Present value technique Terminal growth rate  0
   2,521,342   Discount rate (Weighted-average capital cost)  7.2
Other significant unobservable inputs used in the present value discount model also include estimated future revenue and operating profit of KIOXIA. In these level 3 significant unobservable inputs, the higher in terminal growth rate, future revenue, and operating profit or the lower in weighted-average capital cost will result the higher fair value of the equity investment in SPC1, while any change in volatility and risk free rate may have either positive or negative impact on the fair value of the investment in SPC1. In addition, the higher in terminal growth rate and the lower in weighted-average capital cost will result in the higher fair value of the investment in SPC2 convertible bonds.
Any positive or negative changes in the above inputs will have a significant and direct impact on the fair value of investments in SPC1 and SPC2, respectively. They are significant, but unobservable. Accordingly, the investments are classified as fair value hierarchy Level 3 and the above inputs may have a significant impact on the value of investments in SPC1 and SPC2.
The sensitivity analysis results for the effect of changes in each long-term investment input classified as Level 3 under sensitivity analysis on fair value are as follows:

Revenue recognition policies
Sale of goods
Revenue is recognized when the customer obtains control of that asset, which is typically upon delivery or shipment depending on the terms of the contract.
When the good is defective, the customer is granted the right to return the defective goods in exchange for a functioning product or cash.
Revenue is measured at the amount of consideration for the sale of goods, reflecting the expected amount of return estimated through historical information. The Group’s right to recover products from customers and refund liability are recognized.
Refund liability is initially measured at the former carrying amount of the product less any expected costs to recover those products. Refund liability is included in other current liabilities (See note 19) and right to recover products from customers is included in other current assets (See note 10).The Group reviews its estimate of expected returns at the end of each reporting period and updates the amounts of the asset and liabilities accordingly.
