**[Wireless Business]** 

**A.** **Overview** 

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 5G market 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.

------

##### [**Table of Contents**](#toc)
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. Additionally, SK O&S, the Company's subsidiary responsible for the operation of the Company's networks, including base stations and related transmission and power facilities, provides customers with quality network services and provides the Company with technological know-how in network operations.

The Company has been maintaining solid profitability based on the stable sales generated from its 5G subscribers, together with efficient investments in, and operation of, its wireless networks and stabilization of market competition. The number of the Company's 5G subscribers has reached its maturation stage and continues to maintain a gradual upward trend. The Company recorded 17.80 million subscribers as of March 31, 2026, of which 5G subscribers accounted for 81%. The Company seeks to enhance profitability through stable market operations while striving to further expand customer choices and benefits in order to minimize the slowdown in the growths of wireless services revenue and Average Revenue Per User ("ARPU"). The Company seeks to achieve solid growth in profit from its wireless telecommunications business even in the mature 5G market by enhancing its fundamental competitive strengths, including product and channel realignment and the optimization of operations centered on customer lifetime value.

**B.** **Industry Characteristics** 

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

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

**C.** **Growth Potential** 

The Korean mobile communications market is considered to have reached its maturation stage with more than a 100% penetration rate. However, the Korean mobile communications market continues to improve in the quality of services with the help of advances in network-related technology and the development of highly advanced smartphones which enable the provision of new information and communications technology ("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 artificial intelligence ("AI") are expected to accelerate the introduction of new services and the growth of Internet-of-Things ("IoT")-based business-to-business ("B2B") businesses.

**[Fixed-line Business]** 

**A.** **Overview** 

SK Broadband's business is divided into the media business segment, which provides IPTV and cable TV services, and the fixed-line business segment, which provides high-speed Internet, telecommunications, leased lines and data center services. For the three months ended March 31, 2026, SK Broadband recorded Won 1.15 trillion in revenue on a consolidated basis, which represented a 3.2% increase from Won 1.11 trillion for the three months ended March 31, 2025. Such increase was primarily attributable to the growth of SK Broadband's high-speed Internet business resulting from an increase in the number of subscribers and the growth of its B2B business primarily focused on new data centers.

For the three months ended March 31, 2026, the media business segment recorded Won 0.47 trillion in revenue, which represented a 1.3% decrease compared to the three months ended March 31, 2025. For the three months ended March 31, 2026, the fixed-line business segment recorded Won 0.68 trillion in revenue, which represented a 6.7% increase compared to the three months ended March 31, 2025.

**B.** **Industry Characteristics** 

The domestic telecommunications service industry displays the typical characteristics of a domestic industry given that its coverage area is limited to Korea. As a result, the size of the industry is greatly affected by the domestic user population and the level of telecommunications service expenditures in light of the domestic income level. Domestic telecommunications companies may expand overseas through mergers and 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 the process of transmitting them to viewers through telecommunications facilities. The broadcasting market can primarily 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.

##### [**Table of Contents**](#toc)
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 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 various needs of subscribers by developing new services and penetrating the market. Fixed-line telecommunications services have become essential commodities 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, due to the government's restrictive licensing policies aimed at efficient resource allocation, the Korean fixed-line services industry is marked by a high level of market concentration. In the fixed-line and wireless services markets, an oligopolistic structure has been established, centered around the Company (including SK Broadband), KT and LG U+. However, with the development of faster and more stable telecommunications technologies, integrated convergence products combining fixed-line and wireless communications with broadcasting have become the market standard. Consequently, competition among operators is now centered on providing high-quality services and ensuring customer satisfaction.

The high-speed Internet market continues to grow as mobile data traffic surges due to the expanding use of mobile devices for activities such as AI utilization, video streaming and online gaming. In particular, Wi-Fi services, which provide a stable and fast communication environment without imposing significant additional costs despite increased usage, have become essential communication services. Consequently, demand for Giga Internet, necessary for providing these services, is expanding, and related businesses are growing steadily.

In the pay TV market, competition is shifting from a focus on traditional channels and platforms to a content-centric model due to the expansion of global OTT services. Consequently, the Company is pursuing content differentiation to reflect the rapid changes in viewers' content consumption preferences and usage patterns, and is seeking new growth opportunities in the home platform sector by providing personalized services utilizing AI technology, smart TVs and set-top boxes.

In the enterprise business market, growth opportunities are expanding, particularly in new areas such as AI data centers. Furthermore, to respond to continually increasing market demand and strengthen business competitiveness, the Company is focusing on securing core infrastructure, such as data centers and dedicated lines, and continues its efforts to establish a stable revenue base.

\*\* With respect to fixed-line telephone, the number of subscribers was calculated based on the number of fixed-line and VoIP subscribers of the Company, KT and LG U+.

\*\*\* High-speed Internet and fixed-line telephone subscribers represent the number of subscribers as of February 28, 2026, while IPTV and cable TV subscribers represent the average number of subscribers in the second half of 2024.

**D.** **Cyclical Nature and Seasonality** 

There is little difference among the services provided by operators of high-speed Internet, fixed-line telephone and broadcasting services. Such services, which demonstrate characteristics of essential public utilities, are subject to a subscriber-based business model, and are not sensitive to cyclical economic changes. Due to the low income elasticity of telecommunications services, the overall telecommunications market is not expected to be particularly affected by an economic downturn.

**\*\*** With respect to fixed-line telephone, the market share was calculated based on market shares among SK Broadband, KT and LG U+ and is based on the number of fixed-line and VoIP subscribers. 

**\*\*\*** Market shares for the high-speed Internet and fixed-line telephone markets are based on the market shares as of February 28, 2026, and market shares for the IPTV and cable TV markets are based on the average number of subscribers in the second half of 2024. 

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. The basic telecommunications business is characterized by high barriers to entry, as it requires authorization from the Minister of the MSIT under the Telecommunications Business Act, and an oligopolistic structure has been established, comprising SK Broadband, KT and LG U+.

**[Other Businesses]** 

**A.** **Other businesses** 

SK Stoa operates the commercial retail data broadcasting channel business, offering 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.

**C.** **Business-related Pollutants and Environmental Protection** 

**[SK Telecom]** 

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

**[SK Broadband]** 

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

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

**2. Dividends and Others** 

**A.** **Dividend Policy** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Financial Metrics and Calculation Methods Used to Determine Dividend Targets

In April 2024, the Company disclosed its shareholder return policy for fiscal years 2024 through 2026, under which the total amount of shareholder return for each year is expected to be at least 50% of the adjusted profit for the year on a consolidated basis. Shareholder returns are expected to be provided in the form of cash dividend distribution and/or through acquisition and cancellation of the Company's treasury shares. The Board of Directors will make its determinations on dividends in accordance with such policy.

Adjusted consolidated profit is based on profit attributable to controlling interests, excluding one-time non-recurring gains and losses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Outlook for Future Dividend Levels and Future Dividend Policy Direction

The Company seeks to enhance its enterprise value through distribution of cash dividends based on stable business performance and by increasing long-term shareholder returns based on sustainable growth. The Company has established and is implementing a capital allocation strategy that balances the use of additional free cash flow generated from enhancement in performance and operational improvement across shareholder returns, investments for growth and enhancement in financial structure.

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

In accordance with the global trend towards stable dividend distribution, the Company adopted a quarterly dividend distribution policy through the approval of certain amendments to the Company's Articles of Incorporation at the 37<sup>th</sup> General Meeting of Shareholders held in March 2021 and has been distributing quarterly dividends since the second quarter of 2021.

The Company has engaged in repurchases and cancelations of its own shares from time to time to enhance its enterprise value in consideration of the market price of the Company's shares and its financial resources. From 2020 to 2021, the Company purchased approximately Won 500 billion of treasury shares, and in May 2021, the Company canceled 8,685,568 units of previously acquired treasury shares (10.76% of the total number of shares issued at the time) to enhance shareholder value. In addition, in 2023, the Company purchased approximately Won 300 billion of treasury shares, and in February 2024, the Company canceled 4,043,091 units of treasury shares (1.85% of the total number of shares issued at the time).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Policies for Loss Allowance

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

**Independent Auditors' Review Report** 

<u>Based on a report originally issued in Korean</u>

**To the Board of Directors and Shareholders** 

**SK Telecom Co., Ltd.** 

**Reviewed financial statements** 

We have reviewed the accompanying condensed consolidated interim financial statements of SK Telecom Co., Ltd. and its subsidiaries (the "Group"), which comprise the condensed consolidated interim statement of financial position as of March 31, 2026, the condensed consolidated interim statements of income, comprehensive income, changes in equity and cash flows for the three-month periods ended March 31, 2026 and 2025, and notes, including a summary of material accounting policies and other explanatory information.

**Management's responsibility** 

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

**Auditors' review responsibility** 

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

We conducted our reviews in accordance with the Review Standards for Quarterly and Semiannual Financial Statements established by the Securities and Futures Commission of the Republic of Korea. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Korean Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

**Conclusion** 

Based on our reviews, nothing has come to our attention that causes us to believe that the accompanying condensed consolidated interim financial statements referred to above do not present fairly, in all material respects, in accordance with K-IFRS No.1034, *Interim Financial Reporting*.

------

##### [**Table of Contents**](#toc)
**Other matters** 

The consolidated statement of financial position of the Group as of December 31, 2025, and the related consolidated statements of income, comprehensive income, changes in equity and cash flows for the year then ended, which are not accompanying this report, were audited by us in accordance with Korean Standards on Auditing and our report thereon, dated March 10, 2026, expressed an unmodified opinion. The accompanying consolidated statement of financial position of the Group as of December 31, 2025, presented for comparative purposes, is not different from that audited by us from which it was derived in all material respects.

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

KPMG Samjong Accounting Corp.

Notes to the Condensed Consolidated Interim Financial Statements

March 31, 2026 and 2025

**2.** **Basis of Preparation** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Statement of compliance

These condensed consolidated interim financial statements were prepared in accordance with Korean International Financial Reporting Standard ("KIFRS") 1034 *Interim Financial Reporting* as part of the period covered by the Group's KIFRS annual financial statements. These condensed consolidated interim financial statements do not include all of the disclosures required for full annual financial statements. Selected explanatory notes are included to explain events and transactions that are significant to an understanding of the changes in financial position and performance of the Group since December 31, 2025. The accompanying condensed consolidated interim financial statements have been translated into English from the Korean language financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Use of estimates and judgments

1) Critical judgments, assumptions and estimation uncertainties

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

In preparing these condensed consolidated interim financial statements, the significant judgments made by management in applying the Group's accounting policies and the key sources of estimation uncertainty were the same as those that applied to the consolidated financial statements as of and for the year ended December 31, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Use of estimates and judgments, Continued

2) Fair value measurement

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

The information about assumptions used for fair value measurements is included in note 29.

**3.** **Material Accounting Policies** 

The material accounting policies applied by the Group in these condensed consolidated interim financial statements are the same as those applied by the Group in its consolidated financial statements as of and for the year ended December 31, 2025, except for the adoption of new and revised KIFRS applied from January 1, 2026, which are summarized below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) New and amended standards and interpretations applied by the Group

The Group has applied the following new and amended standards and interpretations for annual period beginning after January 1, 2026. The following amended KIFRS is effective from January 1, 2026 and it did not have a material impact on the Group's condensed consolidated interim financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Classification and measurement of financial instruments (Amendments to KIFRS 1109 ' *Financial Instruments'* and KIFRS 1107 ' *Financial Instruments: Disclosures* ')

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Contracts referencing nature-dependent electricity (Amendments to KIFRS 1109 ' *Financial Instruments'* and KIFRS 1107 ' *Financial Instruments: Disclosures* ')

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Annual Improvements to KIFRS - Volume 11

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) New and amended standards and interpretations that are issued, but not yet applied by the Group

The new and amended standard and interpretation that is issued, but not yet effective is disclosed below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• KIFRS 1118 *'Presentation and Disclosure in Financial Statements'* 

KIFRS 1118 *'Presentation and Disclosure in Financial Statements'* replaces KIFRS 1001 *'Presentation of Financial Statements'*. KIFRS 1118 is expected to enhance comparability of financial performance among similar entities by providing useful information to users in analyzing and comparing an entity's financial performance, with a focus on the statement of profit or loss.

KIFRS 1118 shall be applied for annual periods beginning on or after January 1, 2027, and earlier application is permitted. An entity shall apply this standard retrospectively in accordance with KIFRS 1008 *'Accounting Policies, Changes in Accounting Estimates and Errors'*. Accordingly, comparative information for the annual period ended December 31, 2026 will be restated in accordance with KIFRS 1118.

The Group is currently analyzing the key accounting policies that are expected to result in significant differences from those applied in the current financial statements upon adoption of KIFRS 1118.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) The Group applies the practical expedient that allows the Group to estimate the loss allowance for accounts
receivable – trade at an amount equal to the lifetime expected credit losses. The expected credit losses include the forward-looking information. To make the assessment, the Group uses its historical credit loss experience over the past three
years and classifies the accounts receivable – trade by their credit risk characteristics and days overdue.

Due to the nature of its business, which involves both fixed-line and wireless telecommunications, the Group's accounts receivables from telecommunications revenue primarily consist of receivables from individual customers. As there are no significant differences in credit terms among customers, there is no material concentration of credit risk.

Receivables related to other revenue mainly consist of receivables from corporate customers. The Group transacts only with corporate customers whose credit risk is assessed as low. In addition, the Group is not exposed to significant credit concentration risk as the Group monitors the credit ratings of these customers on a regular basis and evaluates their creditworthiness accordingly. Although contract assets are subject to the expected credit loss assessment, no significant credit risk has been identified.

**29.** **Financial Risk Management** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Financial risk management

The Group is exposed to market risk, credit risk and liquidity risk. Market risk refers to the risk of fluctuations in market variables such as foreign exchange rates, interest rates and the prices of financial instruments. The Group has established a risk management framework to monitor and manage these risks on an ongoing basis.

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

1) Market risk

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Currency risk

The Group is exposed to foreign currency risk arising from revenues and expenses denominated in foreign currencies in the course of its global operations. The primary foreign currencies in which such risk arises are the USD, EUR and others. The Group establishes its currency risk management policy by considering the nature of each business and the availability of hedging or risk-mitigating strategies for each Group entity. The Group regularly monitors, evaluates, and manages its foreign currency exposures through established risk management processes for receivables and payables denominated in foreign currencies. Currency risk arises from both forecasted transactions and recognized assets and liabilities which are denominated in a currency other than the functional currency of each Group entity.

The Group has entered into cross currency swaps to hedge against currency risk related to foreign currency debentures.

As of March 31, 2026, a hypothetical change in exchange rates by 10% would have increased (decreased) the Group's profit before income tax and equity as follows:

---

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Interest rate risk

The Group is exposed to interest rate risk arising from its borrowings, debentures and long-term payables – other. As the Group's interest-bearing assets are predominantly fixed-rate instruments, changes in market interest rates do not have a significant impact on the Group's revenue or operating cash flows.

The Group conducts various analyses to manage interest rate risk and optimize its financing structure. To mitigate the impact of interest rate fluctuations, the Group employs a range of strategies, including refinancing, renewing existing borrowings, alternative financing arrangements and hedging.

As of March 31, 2026, the par values of floating-rate borrowings and debentures amount to W200,000 million and W454,020 million, respectively. The Group has entered into interest rate swaps to hedge interest rate risk related to the floating-rate borrowings and debentures. Therefore, changes in interest rates on the underlying floating-rate borrowings and debentures would not have affected profit before income tax for the three-month period ended March 31, 2026.

As of March 31, 2026, the par values of floating-rate long-term payables – other amount to W182,775 million. Assuming all other variables remain constant, the impact of changes in the interest rate of long-term payables – other by 1%p on profit before income tax and equity for the three-month period ended March 31, 2026 is as follows.

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
| *(In millions of won)* | **Profit before income tax** | **Profit before income tax** | **Profit before income tax** | **Equity** | **Equity** | **Equity** |
|  | **If increased by 1%p** | **If increased by 1%p** | **If decreased by 1%p** | **If increased by 1%p** | **If increased by 1%p** | **If decreased by 1%p** |
|  | W | (457) | 457 | W | (336) | 336 |

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) Price fluctuations risk

As of March 31, 2026, the Group holds equity instruments that are traded in an active market and is therefore exposed to the risk of fluctuations in market prices. Assuming all other variables remain constant, the impact of changes in per-share stock price of the equity securities on profit before income tax and equity for the three-month period ended March 31, 2026 is as follows.

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| *(In millions of won)* | **Profit before income tax** | **Profit before income tax** | **Equity** | **Equity** | **Equity** |

2) Credit risk

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

The Group recognizes a loss allowance for accounts receivable – trade. The allowance consists of a specific component for individually significant exposures and a collective component for groups of similar assets where credit losses are expected to occur. The collective loss allowance is determined based on historical data of collection statistics for similar financial assets. Also, the Group's credit risk can arise from transactions with financial institutions related to its cash and cash equivalents, financial instruments and derivatives. To minimize such risk, the Group has a policy to deal only with financial institutions with high credit ratings.

The Group's maximum exposure to credit risk is equal to each financial asset's carrying amount as of March 31, 2026.

3) Liquidity risk

Liquidity risk is the risk that the Group encounters difficulty in meeting the obligations of the financial liabilities. The Group's approach to managing liquidity is to ensure that it maintains sufficient cash and cash equivalents and secures adequate liquidity through various committed credit lines at all times. The Group maintains sufficient liquidity based on its cash-generating capacity from operating activities and available credit facilities.

The Group's accounts payable – other and others includes amounts settled through supplier finance arrangements. The Group pays the amounts within the normal operating cycle, and no collateral is provided in connection with the agreements. As the payment terms have not been substantially modified, the related balances are classified as accounts payable – other and presented as operating cash flows in the statements of cash flows. Accounts payable – other and others relating to the supplier finance arrangements amount to W306,772 million as of March 31, 2026, which equals the amounts already received by the suppliers from the finance provider.

As of March 31, 2026, periods in which cash flows from cash flow hedge derivatives are expected to occur are as follows:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| *(In millions of won)* | **Carrying<br>amount** | **Carrying<br>amount** | **Contractual<br>cash flows** | **Less than 1 year** | **1 -5 years** |

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Capital management

The Group manages its capital to ensure its ability to continue as a going concern while seeking to maximize shareholder returns through the optimization of its debt and equity structure. The overall capital management strategy of the Group is the same as that of the Group as of and for the year ended December 31, 2025.

The Group monitors its debt-to-equity ratio as a key indicator of capital management. This ratio is calculated as total liabilities divided by total equity, based on the amounts presented in the consolidated financial statements.

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

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

The 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 in such valuation methods include swap rate, interest rate, risk premium, and the volatility of stock price, and the Group performs valuation using the inputs which are consistent with natures of assets and liabilities measured.

Interest rates used by the Group for the fair value measurement as of March 31, 2026 are as follows:

---

| | |
|:---|:---|
|  | **Interest rate** |
|  Derivative instruments | 2.06% ~ 8.10% |
|  Borrowings and debentures | 3.49% ~ 4.00% |
|  Long-term payables – other | 3.43% ~ 3.56% |

**Independent Auditors' Review Report** 

<u>Based on a report originally issued in Korean</u> 

**To the Board of Directors and Shareholders** 

**SK Telecom Co., Ltd.** 

**Reviewed financial statements** 

We have reviewed the accompanying condensed separate interim financial statements of SK Telecom Co., Ltd. (the "Company"), which comprise the condensed separate interim statement of financial position as of March 31, 2026, the condensed separate interim statements of income, comprehensive income, changes in equity and cash flows for the three-month periods ended March 31, 2026 and 2025, and notes, including a summary of material accounting policies and other explanatory information.

**Management's responsibility** 

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

**Auditors' review responsibility** 

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

We conducted our reviews in accordance with the Review Standards for Quarterly and Semiannual Financial Statements established by the Securities and Futures Commission of the Republic of Korea. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Korean Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

**Conclusion** 

Based on our reviews, nothing has come to our attention that causes us to believe that the accompanying condensed separate interim financial statements referred to above do not present fairly, in all material respects, in accordance with K-IFRS No.1034, *Interim Financial Reporting*.

------

##### [**Table of Contents**](#toc)
**Other matters** 

The separate statement of financial position of the Company as of December 31, 2025, and the related separate statements of income, comprehensive income, changes in equity and cash flows for the year then ended, which are not accompanying this report, were audited by us in accordance with Korean Standards on Auditing and our report thereon, dated March 10, 2026, expressed an unmodified opinion. The accompanying separate statement of financial position of the Company as of December 31, 2025, presented for comparative purposes, is not different from that audited by us from which it was derived in all material respects.

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

Notes to the Condensed Separate Interim Financial Statements

March 31, 2026 and 2025

**2.** **Basis of Preparation** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Statement of compliance

These condensed separate interim financial statements were prepared in accordance with Korean International Financial Reporting Standard ("KIFRS") 1034 *Interim Financial Reporting* as part of the period covered by the Company's KIFRS annual financial statements. These condensed separate interim financial statements do not include all of the disclosures required for full annual financial statements. Selected explanatory notes are included to explain events and transactions that are significant to an understanding of the changes in financial position and performance of the Company since December 31, 2025. The accompanying condensed separate interim financial statements have been translated into English from the Korean language financial statements.

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

Notes to the Condensed Separate Interim Financial Statements

March 31, 2026 and 2025

**2.** **Basis of Preparation, Continued** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Use of estimates and judgments

1) Critical judgments, assumptions and estimation uncertainties

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

In preparing these condensed separate interim financial statements, the significant judgments made by management in applying the Company's accounting policies and the key sources of estimation uncertainty were the same as those that applied to the separate financial statements as of and for the year ended December 31, 2025.

2) Fair value measurement

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

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

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

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1:<br>| quoted prices (unadjusted) in active markets for identical assets or liabilities; |
| &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 2:<br>| 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 |
| &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 3:<br>| inputs for the asset or liability that are not based on observable market data (unobservable inputs). |

---

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

The information about assumptions used for fair value measurements is included in note 28.

**3.** **Material Accounting Policies** 

The material accounting policies applied by the Company in these condensed separate interim financial statements are the same as those applied by the Company in its separate financial statements as of and for the year ended December 31, 2025, except for the adoption of new and revised KIFRS applied from January 1, 2026, which are summarized below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) New and amended standards and interpretations applied by the Company

The Company has applied the following new and amended standards and interpretations for annual period beginning after January 1, 2026. The following amended KIFRS is effective from January 1, 2026 and it did not have a material impact on the Company's condensed separate interim financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Classification and measurement of financial instruments (Amendments to KIFRS 1109 ' *Financial Instruments'* and KIFRS 1107 ' *Financial Instruments: Disclosures* ')

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Contracts referencing nature-dependent electricity (Amendments to KIFRS 1109 ' *Financial Instruments'* and KIFRS 1107 ' *Financial Instruments: Disclosures* ')

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Annual Improvements to KIFRS - Volume 11

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) New and amended standards and interpretations that are issued, but not yet applied by the Company

The new and amended standard and interpretation that is issued, but not yet effective is disclosed below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• KIFRS 1118 *'Presentation and Disclosure in Financial Statements'* 

KIFRS 1118 *'Presentation and Disclosure in Financial Statements'* replaces KIFRS 1001 *'Presentation of Financial Statements'*. KIFRS 1118 is expected to enhance comparability of financial performance among similar entities by providing useful information to users in analyzing and comparing an entity's financial performance, with a focus on the statement of profit or loss.

KIFRS 1118 shall be applied for annual periods beginning on or after January 1, 2027, and earlier application is permitted. An entity shall apply this standard retrospectively in accordance with KIFRS 1008 *'Accounting Policies, Changes in Accounting Estimates and Errors'*. Accordingly, comparative information for the annual period ended December 31, 2026 will be restated in accordance with KIFRS 1118.

The Company is currently analyzing the key accounting policies that are expected to result in significant differences from those applied in the current financial statements upon adoption of KIFRS 1118.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) The Company applies the practical expedient that allows the Company to estimate the loss allowance for accounts
receivable – trade at an amount equal to the lifetime expected credit losses. The expected credit losses include the forward-looking information. To make the assessment, the Company uses its historical credit loss experience over the past
three years and classifies the accounts receivable – trade by their credit risk characteristics and days overdue.

Due to the nature of its business, which involves wireless telecommunications, the Company's accounts receivables from telecommunications revenue primarily consist of receivables from individual customers. As there are no significant differences in credit terms among customers, there is no material concentration of credit risk.

Receivables related to other revenue mainly consist of receivables from corporate customers. The Company transacts only with corporate customers whose credit risk is assessed as low. In addition, the Company is not exposed to significant credit concentration risk as the Company monitors the credit ratings of these customers on a regular basis and evaluates their creditworthiness accordingly. Although contract assets are subject to the expected credit loss assessment, no significant credit risk has been identified.

**28.** **Financial Risk Management** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Financial risk management

The Company is exposed to market risk, credit risk and liquidity risk. Market risk refers to the risk of fluctuations in market variables such as foreign exchange rates, interest rates and the prices of financial instruments. The Company has established a risk management framework to monitor and manage these risks on an ongoing basis.

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

1) Market risk

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Currency risk

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

The Company has entered into cross currency swaps to hedge against currency risk related to foreign currency debentures.

As of March 31, 2026, a hypothetical change in exchange rates by 10% would have increased (decreased) the Company's profit before income tax and equity as follows:

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
| *(In millions of won)* | **Profit before income tax** | **Profit before income tax** | **Profit before income tax** | **Equity** | **Equity** | **Equity** |

1) Market risk, Continued

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Interest rate risk

The Company is exposed to interest rate risk arising from its borrowings, debentures and long-term payables – other. As the Company's interest-bearing assets are predominantly fixed-rate instruments, changes in market interest rates do not have a significant impact on the Company's revenue or operating cash flows.

The Company conducts various analyses to manage interest rate risk and optimize its financing structure. To mitigate the impact of interest rate fluctuations, the Company employs a range of strategies, including refinancing, renewing existing borrowings, alternative financing arrangements and hedging.

As of March 31, 2026, the par values of floating-rate borrowings and debentures amount to W200,000 million and W454,020 million, respectively. The Company has entered into interest rate swaps to hedge interest rate risk related to the floating-rate borrowings and debentures. Therefore, changes in interest rates on the underlying floating-rate borrowings and debentures would not have affected profit before income tax for the three-month period ended March 31, 2026.

As of March 31, 2026, the par values of floating-rate long-term payables – other amount to W182,775 million. Assuming all other variables remain constant, the impact of changes in the interest rate of long-term payables – other by 1%p on profit before income tax and equity for the three-month period ended March 31, 2026 is as follows:

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
| *(In millions of won)* | **Profit before income tax** | **Profit before income tax** | **Profit before income tax** | **Equity** | **Equity** | **Equity** |
|  | **If increased by 1%p** | **If increased by 1%p** | **If decreased by 1%p** | **If increased by 1%p** | **If increased by 1%p** | **If decreased by 1%p** |
|  | W | (457) | 457 | W | (336) | 336 |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) Price fluctuations risk

As of March 31, 2026, the Company holds equity instruments that are traded in an active market and is therefore exposed to the risk of fluctuations in market prices. Assuming all other variables remain constant, the impact of changes in the per-share stock price of the equity securities on profit before income tax and equity for the three-month period ended March 31, 2026 is as follows:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| *(In millions of won)* | **Profit before income tax** | **Profit before income tax** | **Equity** | **Equity** | **Equity** |
|  | **If increased by 10%p** | **If decreased by 10%p** | **If increased by 10%p** | **If increased by 10%p** | **If decreased by 10%p** |

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Financial risk management, Continued

2) Credit risk

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

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

The Company's maximum exposure to credit risk is equal to each financial asset's carrying amount as of March 31, 2026.

3) Liquidity risk

Liquidity risk is the risk that the Company encounters difficulty in meeting the obligations of the financial liabilities. The Company's approach to managing liquidity is to ensure that it will always maintain sufficient cash and cash equivalents balances and have enough liquidity through various committed credit lines. The Company maintains enough liquidity within credit lines through active operating activities.

The Company's accounts payable – other and others includes amounts settled through supplier finance arrangements. The Company pays the amounts within the normal operating cycle, and no collateral is provided in connection with the agreements. As the payment terms have not been substantially modified, the related balances are classified as accounts payable – other and presented as operating cash flows in the statements of cash flows. Accounts payable – other and others relating to the supplier finance arrangements amount to W306,772 million as of March 31, 2026, which equals to the amounts already received by the suppliers from the finance provider.

As of March 31, 2026, periods in which cash flows from cash flow hedge derivatives are expected to occur are as follows:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| *(In millions of won)* | **Carrying<br>amount** | **Carrying<br>amount** | **Contractual<br>cash flows** | **Less than<br>1 year** | **1 – 5<br>years** |

|  Liabilities |  | (225) | (225) | (225) |  |

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Capital management

The Company manages its capital to ensure its ability to continue as a going concern while seeking to maximize shareholder returns through the optimization of its debt and equity structure. The overall capital management strategy of the Company is the same as that for the year ended December 31, 2025.

The Company monitors its debt-to-equity ratio as a key indicator of capital management. This ratio is calculated as total liabilities divided by total equity, based on the amounts presented in the separate financial statements.

Debt-to-equity ratio as of March 31, 2026 and December 31, 2025 are as follows:

---

| | | | |
|:---|:---|:---|:---|
| *(In millions of won)* | **March 31, 2026** | **March 31, 2026** | **December 31, 2025** |

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Fair value, Continued

1) Fair value and carrying amount of financial assets and liabilities, including fair value hierarchy as of March 31, 2026 and December 31, 2025 are as follows, Continued:

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

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

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

Interest rates used by the Company for the fair value measurement as of March 31, 2026 are as follows:

---

| | |
|:---|:---|
|  | **Interest rate** |
|  Derivative instruments | 2.06% ~ 4.20% |
|  Borrowings and debentures | 3.49% ~ 3.97% |
|  Long-term payables – other | 3.43% ~ 3.56% |
