1. Business Overview

Each company in the consolidated entity is a separate legal entity providing independent services and products. The Company’s business is primarily separated into (1) the wireless business consisting of cellular voice, wireless data and wireless Internet services, (2) the fixed-line business consisting of fixed-line telephone, high-speed Internet, data and network lease services, among others and (3) other businesses consisting of commercial retail data broadcasting channel business, among others.

Set forth below is a summary description of the business of each of the Company’s material consolidated subsidiaries.

[Wireless Business]

Wireless telecommunications companies provide services based on competitive strengths in handheld devices, affordable pricing, network coverage and an extensive contents library. The Company continues to maintain its reputation as the unparalleled premium network operator in the 3G, 4G and 5G markets on the basis of its technological leadership and network management technology. With the world’s first commercialization of 5G technology in 2019, the Company continues to maintain its position as the top network operator in the 5G era and strives to provide differentiated services to its customers.

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

11

The Company plans to maintain stable growth in the sales of its wireless business based on a solid increase in the number of 5G subscribers, while continuously enhancing profitability by pursuing efficient investments in, and operation of, its wireless networks and leveraging the stabilization of market competition.

The Company has been providing its customers with various subscription packages through “T Universe,” the Company’s subscription business, in partnership with domestic and international businesses. In addition, the Company is continually updating key functions and technologies of “A. (Adot),” the world’s first commercialized Korean language GPT-3-based service, in preparation of A.’s official service launch, while further strengthening the social and community functions of “ifland” with a goal to transform it into a globally leading metaverse service.

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

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

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

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

12

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

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

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

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

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

The Company successfully completed the Spin-off in 2021 to maximize shareholder value and launched “SKT 2.0.” Concurrently, the Company reorganized its business to center around five major business areas and is seeking maximization of overall corporate value by establishing and executing strategies optimized for each business segment and pursuing growth in each segment. For the six months ended June 30, 2023, the Company recorded Won 4.31 trillion in operating revenue and Won 0.46 trillion in operating profit on a consolidated basis. The increased competitiveness of telecommunications services and the rapid progress in new growth businesses such as B2B have enabled the Company to continue to improve its operating results.

SK Telink, a consolidated subsidiary of the Company, operates its MVNO service, “SK 7Mobile,” which is offered at reasonable rates and provides excellent quality. SK Telink is increasing its efforts to develop low-cost distribution channels and create niche markets through targeted marketing towards customers including foreign workers, middle-aged adults and students.

SK O&S, a subsidiary of the Company responsible for the operation of the Company’s base stations and related transmission and power facilities, offers quality fixed-line and wireless network services to customers, including mobile office products to business customers. In addition, Service Ace is developing its competence as a marketing company while providing top-quality customer service.

PS&Marketing, a subsidiary of the Company, provides a sales platform for products of the Company and SK Broadband including fixed-line and wireless telecommunications products that address customers’ needs for various convergence products. PS&Marketing provides differentiated service to clients through the establishment of new sales channels and product development.

[Fixed-line Business]

For the six months ended June 30, 2023, SK Broadband recorded Won 2.13 trillion in revenue on a consolidated basis, which represented a 3.4% increase from Won 2.06 trillion for the six months ended June 30, 2022. Such increase was primarily attributable to the growth of SK Broadband’s media business resulting from an increase in the number of subscribers and the growth of its B2B business resulting from, among other things, the operation of new data centers.

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

13

For the six months ended June 30, 2023, the media business segment recorded Won 946.3 billion in revenue, which represented a 0.9% increase compared to the six months ended June 30, 2022. For the six months ended June 30, 2023, the fixed-line business segment recorded Won 1.18 trillion in revenue, which represented a 5.6% increase compared to the six months ended June 30, 2022.

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

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

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

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

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

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

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

14

High-speed Internet and fixed-line telephone services operate in mature markets that are comparatively less sensitive to cyclical economic changes as the services provided by different operators have become less differentiated. TV services have become necessities that provide broadcasting, and the market, which is subject to a subscriber-based business model, has little sensitivity to cyclical economic changes. Overall, the telecommunications services market is not expected to be particularly affected by economic downturns due to the low income elasticity of demand for telecommunications services.

Set forth below is the historical market share of the Company.

SK Broadband is engaged in a number of business areas including high-speed Internet, home telephone, corporate business, IPTV and cable TV pursuant to the relevant communications regulations such as the Telecommunications Business Act, the Internet Multimedia Broadcast Services Act and the Broadcasting Act. In each of its principal business areas, SK Broadband competes on the basis of price, service quality and speed. In the IPTV business, the ability to offer complex services and differentiated contents are becoming increasingly important. General telecommunications businesses operate in a licensed industry with a high barrier of entry, which is dominated by SK Broadband, KT and LG U+.

[Other Businesses]

The commercial retail data broadcasting channel business offers an interactive service that integrates television home shopping and data home shopping services. Such integrated service allows television viewers to organize various product categories on the television screen and select and purchase desired products using a television remote control or mobile device, unlike traditional home shopping services that only allowed for real-time purchase through the relevant broadcast.

15

In order to secure core competencies at an early stage and achieve differentiation, the Company has been actively searching for high-efficiency television channels while increasing the competitiveness of its content production capacity by building the Company’s own media center and adopting a media wall with the objective of transforming it into an eco-friendly digital studio. In addition to enhancing the convenience of shopping experience by offering various media content on its mobile live platform, the Company was the first in the industry to launch a cloud-based television application service, “Stoa ON,” which provides personalized digital television shopping services. Furthermore, the Company has been establishing itself as a leading shopping channel service provider by securing a diverse product portfolio and engaging in product development in areas ranging from fashion to health food.

[Wireless Business]

As of June 30, 2023, based on the Company’s standard monthly subscription plan, the basic service fee was Won 12,100 (including value-added tax) and the usage fee was Won 1.98 per second. Among the 4G-based plans, the “T-Plan Safe 4G” provides 4 GB of data and unlimited voice calls at Won 50,000 per month (including value-added tax). Among the 5G-based plans, the “Basic” plan provides 8 GB of data and unlimited voice calls at Won 49,000 per month (including value-added tax). On June 1, 2023, the Company newly launched the “5G 0 Youth” plan, which actively reflects the data usage patterns and lifestyle trends of the younger demographics. The Company plans to continue to introduce new services that reach out to different customer segments. The Company provides a variety of other subscription plans catering to subscriber demand, which may be reviewed on the Company’s website at www.tworld.co.kr.

[Fixed-line Business]

On May 15, 2023, SK Broadband newly launched the Internet Protocol Cable TV (“IP CATV”) product. Existing cable TV services were allowed to transmit broadcasting contents only through the radio frequency (“RF”) method. However, pursuant to recent amendments to the Broadcasting Act which recognize technology neutrality, cable TV services are now allowed to transmit broadcasting contents through non-RF methods, thereby allowing the Company to introduce the new IP CATV product.

Compared to the RF method, the Internet protocol method provides diverse and high-quality services on a more stable basis. The Company expects these factors will lead to greater customer satisfaction and competitiveness of its cable TV services products through improvement in broadcasting quality.

In order to cater to the diverse needs of the customers, the IP CATV product is offered through three plans. The “B tv pop 100” plan offers basic channels (109 channels), the “B tv pop 180” plan offers channels with high viewer ratings (184 channels) and the “B tv pop 230” plan offers all cable TV channels (231 channels). Based on a three-year contract, the plans cost Won 7,700, Won 11,000, and Won 13,200, respectively. As for the B tv pop 180 and B tv pop 230 plans, customers can receive an additional discount of Won 3,300 if they combine the plans with the broadband Internet service.

SK Broadband also provides a variety of other subscription plans based on consumer demand, which may be reviewed on SK Broadband’s website at www.skbroadband.com.

10. Market Conditions and Business Overview of New Business Sectors

[Data production, transaction and utilization businesses, such as the MyData business]

1) Business Area and Purpose of Entry

In July 2022, the Company became the first telecommunications service provider in Korea to acquire a “MyData” financial business license. The Company initiated its MyData service in September 2022 by launching it as an open beta service on its personal authentication service (“PASS”) application. Currently, the Company’s MyData service provides financial health diagnosis and coaching services in addition to providing an aggregated review of a customer’s assets.

Through its MyData business, the Company plans to provide differentiated value to its customers by collecting and analyzing vast amounts of personal credit information dispersed in banks, securities, card and insurance companies.

2) Industry Characteristics

The MyData industry first started in the financial sector in 2022. Following the introduction of the right to data portability, approximately 100 companies in the finance, big tech, fintech, distribution and communication sectors have been participating or are planning to participate in the MyData businesses, each pursuing different strategies based on its business purposes. Currently, competition in the MyData industry is accelerating as participants attempt to pre-emptively occupy digital platforms. The key value of the MyData business is its ability to integrate financial information scattered across various corporate services into a single platform. Companies can leverage this ability to provide customized services, ultimately resulting in increased customer loyalty and userbase.

20

It is also a regulated industry, closely related to the government’s medical policies and oversight. As technology advances, medical devices are becoming increasingly complex and diversified. The market for high value-added products with advanced technology is led by a small number of large companies, while the market for low-priced products and certain other markets are led by specialized small- and medium-sized companies.

3) Industry Size and Growth Potential

In 2022, the size of the medical device market in Korea amounted to Won 11.878 trillion*, showing an annual growth rate of 13.9%.
