韓國電力提交6-K自願披露企業管治報告 合規率73.3%並恢復派息每股1,542韓元
AI 繁中摘要
📋 KEPCO 提交 6-K 表格,自願披露截至 2026 年 5 月 31 日的企業管治報告,以提升投資者對其治理結構的理解。報告顯示,公司於 15 項關鍵治理指標中的合規率為 73.3%,涵蓋股東權利、董事會運作及審計機制。
在股東回報方面,KEPCO 於 2025 財政年度(FY2025)成功扭虧為盈,恢復派發現金股息每股 1,542 韓元(約 3.2% 股息率),結束了因 2021-2023 年累計虧損而暫停派息的局面。公司表示,儘管財務狀況仍具挑戰(2025 年負債對權益比率為 444%),但在兼顧未來財務穩健性的前提下,盡力回饋股東。然而,由於近期虧損及業務環境不確定性,公司尚未確立中長期股東回報政策。
董事會結構方面,KEPCO 由 7 名常務董事(包括 CEO)及 8 名非執行董事組成,非執行董事佔多數以確保獨立性。董事會主席由非執行董事擔任,並設有四個委員會:審計委員會、ESG 委員會、董事提名委員會及電力系統委員會。審計委員會由三名成員組成(包括兩名非執行董事及一名常務董事),當中至少有一名會計或財務專家,負責監督財務報告內部控制及管理審計。ESG 委員會則由三名非執行董事及一名常務董事組成,專注於可持續發展策略。
報告亦強調股東參與,包括採用電子投票系統,但部分股東大會未能避開高峰日期。2025 年,董事會會議出席率平均達 93.2%(常規會議)及 90.7%(臨時會議)。
對投資者的潛在影響:KEPCO 透過此報告展示其對透明治理的承諾,尤其在恢復派息後,有助增強投資者信心。然而,高負債水平及缺乏明確的中長期派息政策,仍為風險因素。公司持續優化內部監控及風險管理,並維持非執行董事主導的獨立架構,長遠有利於企業價值。💡

Corporate Governance 1. Corporate Governance Policy (1) Shareholders KEPCO has been striving for transparent governance since its listing on the stock market to protect shareholders’ rights and enhance shareholder value. (2) Board of Directors In order to ensure transparency in its corporate governance, anyone interested in KEPCO’s corporate governance practice can access, on its corporate website, Articles of Incorporation of KEPCO, Regulations Concerning the Board of Directors, Regulations Concerning Operations of the Audit Committee and KEPCO’s other internal regulations related to its corporate governance. To ensure the transparency of its corporate governance through independent decision-making processes, KEPCO maintains non-standing directors as a majority of the Board. The Board of Directors is composed of seven standing directors, including the CEO, and eight non-standing directors. The chairperson of the Board of Directors is appointed from among non-standing directors to ensure the fair collection of opinions and suggestions regarding overall management. Furthermore, non-standing directors are elected from among professionals with expertise in finance, accounting, labor management and energy industries, so as to fulfill their roles of consulting and advising on the agenda of board meetings. KEPCO strives to provide sufficient information on each agenda to directors before the board meeting so that the directors can make an informed decision. (3) Audit The Audit Committee inspects the accounting and management issues, and also evaluates the operation of Internal Control over Financial Reporting. Moreover, it supervises the performance of directors and management to ensure that they make rational business decisions. The Audit Committee consists of three directors, two of whom are required to be non-standing directors. The chairperson of the committee is required to be a non-standing director. One member of the Audit Committee is a standing director and is appointed upon the recommendation of the Director Nomination Committee and by the resolution of the general meeting of shareholders. Other members of the Audit Committee who are non-standing directors are appointed from among non-standing directors and by the resolution of the general meeting of shareholders. The Audit Committee maintains objectivity in conducting audits, by working separately from the directors and management. If it is necessary to carry out its duties, the committee may request any related executive or employee to attend committee meetings, to submit reports and to state his or her opinion. Also, the committee may seek advice from external experts at the company’s expense. 2. Key Characteristics of Corporate Governance Structure (1) Organization of the Board of Directors As the highest decision-making body of the company, the Board of Directors is composed of seven standing directors (including the CEO) and eight non-standing directors, securing its independence by having non-executive directors constitute a majority of the Board. Non-standing directors are elected from candidates with ample industrial or professional knowledge and experience without discrimination based on sex, race, age, nationality or cultural background so as to respond flexibly and professionally to a diversifying business environment. For fair and transparent operation of the Board of Directors, the chairperson is appointed from among non-standing directors following the review and resolution of the Committee for Management of Public Institutions under the Ministry of Climate, Energy and Environment pursuant to Article 21 of the Act on the Management of Public Institutions. (2) Subcommittees in the Board of Directors KEPCO operates four subcommittees under the Board of Directors, namely, the Audit Committee, the ESG Committee, the Director Nomination Committee, and the Power System Committee to strengthen the preliminary review and support the rational decision-making of the Board of Directors. The Audit Committee consists of two non-standing directors and one standing director, at least one of whom is appointed from among accounting or financial experts to conduct an audit of business and accounting. In December 2020, as the first public enterprise in Korea, KEPCO additionally established an Environment, Social and Governance (ESG) Committee under its Board of Directors to reinforce its ESG-based management system. The ESG Committee consists of three non-standing directors and one standing director and is responsible for resolving major management issues related to ESG, establishing ESG management strategies and business plans, checking on the overall direction of sustainable management and monitoring achievements and issues related to such performance. The Director Nomination Committee is in charge of the appointment of new directors. The Committee members consist of non-standing directors and other external members selected by the Board of Directors. The total number of members must be not less than five and not more than fifteen. The Board of Directors appoints external members comprising less than half of the members to maintain independence in the appointment of directors. The Power System Committee consists of three non-standing directors and one standing director and is in charge of the preliminary review of major agendas that require board approval, the deliberation of key management issues related to the power system, such as major plans for the power system requested by the board, and the inspection and feedback on the implementation of key policy plans and achievements related to the power system. (3) Expertise of subcommittees in the Board of Directors In order to enhance the expertise of its Board of Directors, KEPCO considers each candidate’s expertise at the document screening stage for director candidates and has actively recruited many experts in various fields. KEPCO appoints members of subcommittees such as the ESG Committee or the Audit Committee based on the professional fields of each non-standing director and also obtains comprehensive advice from the ESG Advisory Committee and the Audit Advisory Committee which are composed of external specialists. In addition, KEPCO strives to strengthen the expertise of its directors by regularly providing education related to internal control over financial reporting and ESG. The Audit Committee consists of three directors, two of whom are required to be non-standing directors and one standing director, and at least one of whom is appointed from among accounting or financial experts to conduct an audit of business and accounting. The ESG Committee consists of three non-standing directors and one standing director and it is in charge of deliberating on major management issues related to ESG, establishing ESG management strategies and related business plans, checking on the overall direction of sustainable management and monitoring and supervising achievements and issues related to such performance. The Director Nomination Committee, when the appointment of executives is required, is composed of a majority of non-standing directors and not less than five and not more than fifteen external members selected by the Board of Directors through a board resolution, thereby ensuring independence in the appointment of directors. The Power System Committee consists of three non-standing directors and one standing director and is in charge of the preliminary review of major agendas that require board approval in the power system sector, the deliberation of key management issues related to the power system such as major plans for the power system requested by the board, and the inspection and feedback on the implementation of key policy plans and achievements related to the power system. In addition, in order to enhance expertise, KEPCO strives to strengthen the capability of its directors by regularly providing education related to internal control over financial reporting and ESG. (4) Independence of the Board of Directors KEPCO ensures the independence of its Board of Directors so that the directors can carry out their duties of ‘checks and balances’ in a responsible manner. KEPCO supports directors’ and officers’ liability insurance to support their decision-making with a firm conviction, and prohibits any director who has a special interest in an agenda item from participating in the related board resolution. KEPCO also strictly scrutinizes whether a non-standing director candidate has any related-party transaction that would disqualify such candidate from his or her directorship under the Korean Commercial Act. (5) Current State of Corporate Governance Subcommittees Composition (Number of Non-Standing Directors / Number of total Directors) Chairperson (Status as Standing/Non-standing director) Key Roles Board of Directors 8/15 (composed of a majority of non-standing directors) Non-standing Director • Setting business objectives, budget, financing plans and operational plans; • Use of reserve funds; • Settlement of annual accounts; • Acquisition, addition and disposal of generation facilities in excess of 200,000 kW capacity and fixed assets valued at more than Won 30 billion (other than generation facilities and transmission and substation facilities); • Long-term planning for electricity transmission and substation; • Long-term borrowings, corporate debenture issuance and repayments thereof; • Electricity tariff rates; • Disposition of surplus funds; • Investment in or in-kind contributions to other entities; • Debt guarantees for other entities; • Amendment to the Articles of Incorporation; • Establishment and amendment to major internal regulations; • Calling of the general meeting of shareholders and determination of the agenda therefor; • Issuance of new shares and disposition of forfeited shares and fractional shares; • Capital increase and decrease; • Approval of asset revaluation amounts; • Corporate dissolution; • Research and development plans; • Merger, dissolution and guarantee of investee companies; • Composition of the Director Nomination Committee and determination of the criteria for evaluating director nominees; • Management contract with the CEO; • Request for dismissal of the CEO; • Expansion and establishment of regional offices; • Remuneration for executives; • Modification of resolutions previously made by the Board of Directors, according to increases in total expenses (over 10% or 10 billion won) or significant changes to the original plan • Related-party transactions amounting to more than 5% of total equity or 50 billion won; and • Other matters deemed necessary by the CEO or the Board of Directors Director Nomination Committee Not less than five and not more than fifteen (external members less than half of the members) Non-standing Director • Determination of the recruitment method for executive candidates and screening of executive candidates • Determination of candidates to be recommended for executive positions • Negotiation of management contracts with the candidate to be recommended for the CEO position • Other matters and operations related to the recommendation of executive candidates Audit Committee 2/3 Non-standing Director • Conducting audits on the business and accounting of the company and reporting the results • Appointment of external auditors and approval of non-audit services • Other matters stipulated by relevant laws and the Articles of Incorporation ESG Committee 3/4 Non-standing Director Deliberation and resolution on the following matters: • Preliminary review of major agendas related to ESG among matters requiring board approval • Deliberation and resolution on key management issues, including major implementation plans related to ESG management • Deliberation and resolution on other matters deemed necessary by the Board of Directors and the Committee Power System Committee 3/4 Non-standing Director • Preliminary review of major agendas requiring board approval on Power System sector • Deliberation of key management matters related to the power system • Inspection and feedback on the implementation of key policy plans and achievements related to the power system III. Shareholders Core Principle 1. Shareholders’ Rights Detailed Principle 1-① Providing sufficient information on the General Meeting of Shareholders To comply with the legal deadline, KEPCO makes a public disclosure immediately after the board resolution to hold a general meeting of shareholders and announces the time, place, agenda and other details of the meeting at least two weeks before the date of the meeting. KEPCO’s general meetings of shareholders in the period from January 2025 to June 2026 were held as follows: Type Date ofResolution Date of Notice Date of Meeting Period ofNotice Annual General Meeting Feb. 28, 2025 Mar. 11, 2025 Mar. 26, 2025 15 days Feb. 26, 2026 Mar. 10, 2026 Mar. 25, 2026 15 days Extraordinary General Meeting Dec. 20, 2024 Dec. 20, 2024 Jan. 6, 2025 17 days May 9, 2025 May 13, 2025 May 28, 2025 15 days Apr. 10, 2026 Apr. 10, 2026 Apr. 27, 2026 17 days May 6, 2026 May 6, 2026 May 21, 2026 15 days Detailed Principle 1-② Encourage shareholders to participate in the General Meeting KEPCO implements an electronic voting system so that shareholders can participate in the General Meeting and exercise their rights smoothly. Also, in order to facilitate shareholders’ attendance in 2024 and 2025, the Annual General Meetings were held on a date other than the dates that the Korea Listed Companies Association recommends avoiding as there are a concentrated number of companies holding their annual general meetings on those dates. However, with respect to the 65th Annual General Meeting of Shareholders, although we made efforts to avoid holding the meeting on a peak meeting date, after comprehensively considering shareholders’ need for sufficient time to review the agenda items, the voting period, and the financial closing schedule, we were unavoidably required to hold the meeting on a peak meeting date. KEPCO has adopted an electronic voting system to maximize shareholder participation in the general meeting and is making its best efforts to ensure that shareholders can exercise their voting rights smoothly through this system. We will continue to seek ways to enable greater shareholder participation in the future. A list of the agenda items voted on at the general meetings of shareholders in the period from January 2025 to June 2026 is provided below: Date of Meeting Resolution Agenda OutstandingShares Shares Voted Shares for(Approval Rate*) Jan. 6, 2025 Ordinary Election of a Standing Director - Ahn, Jung-Eun 641,964,077 456,649,381 426,269,508(93.3%) Mar. 26, 2025 Ordinary Approval of financial statements for the fiscal year 2024 641,964,077 464,789,138 459,937,089 (99.0%) Ordinary Approval of the maximum aggregate amount of remuneration for directors in 2025 641,964,077 464,789,138 462,491,873 (99.5%) May 28, 2025 Ordinary Election of a Standing Director - Jung, Chi-Kyo 641,964,077 469,488,199 417,919,268 (89.0%) Mar. 25, 2026 Ordinary - Approval of financial statements for the fiscal year 2025 641,964,077 511,345,965 506,568,651(99.1%) Ordinary Approval of the maximum aggregate amount of remuneration for directors in 2026 641,964,077 511,345,965 509,945,280 (99.7%) Extraordinary Approval of amendments to the Articles of Incorporation 641,964,077 511,345,965 510,592,978 (99.9%) Apr. 27, 2026 Ordinary Election of a Standing Director Kim, Jae-Koon 641,964,077 498,013,829 453,564,606 (91.1%) May 21, 2026 Ordinary - Election of a Standing Director as Comptroller & Auditor General and Member of Audit Committee – Kim, Tae-Ok 287,987,428 139,776,433 87,404,563 (62.5%) * Under the Korean Commercial Act, the voting rights of the shareholders who hold shares in excess of three percent of the total number of issued shares are limited to three percent when appointing members of the Audit Committee. * Approval rate is the percentage of the shares voting in favor to the shares voted. Detailed Principle 1-③ Proposal Right of Shareholders KEPCO provides information on the proposal right of shareholders via telephone or in writing, but there have been very few cases of shareholders’ proposals at the General Meeting so far. KEPCO will consistently strive to guarantee the shareholders’ proposal right in accordance with the relevant laws and provide the relevant information on such right through KEPCO’s corporate website. KEPCO assures the proposal right of shareholders in accordance with requirements provided under the Korean Commercial Act. When a certain agenda item is proposed and unless it is against the laws or the Articles of Incorporation of KEPCO, it shall be submitted to the general meeting of shareholders after the resolution by the Board of Directors. Every shareholder who attends the general meeting of shareholders has the right to inquire about and request explanations of the agenda items, unless he or she obviously intends to obstruct the proceedings of the meeting. Shareholders may make a proposal for the general meeting of shareholders, but no shareholder proposal has been submitted to the meetings held by June 2026. Detailed Principle 1-④ Shareholder Return Policy In accordance with provisions in the Korean Commercial Act, Articles of Incorporation of KEPCO and the KEPCO Act, KEPCO is entitled to pay out dividends. KEPCO determines dividends considering its investment plan, future cash flow and financial structure to enhance shareholder value and increase shareholder return. However, as the resolution of the large-scale accumulated deficit that persisted from 2021 to 2023 is urgent, and a flexible dividend policy is required to respond to the rapidly changing internal and external business environments, KEPCO has not established or announced a mid- to long-term shareholder return policy. KEPCO’s dividend payments are finally determined at the annual general meeting of shareholders through resolutions by the Board of Directors and announced immediately via DART. As the timing of the turnaround is uncertain due to the recently accumulated deficit, KEPCO has not announced a specific dividend policy. KEPCO discloses key dividend indicators for the most recent three fiscal years in its business reports and semi-annual reports, and provides dividend payment information for the most recent five fiscal years on its corporate website. Following a return to profitability in the fiscal year 2025, KEPCO paid a dividend of Won 1,542 per share. The dividend record date was the fiscal year end of December 31, 2025, in accordance with Article 15 of KEPCO’s Articles of Incorporation. The dividend was finalized on March 25, 2026, at the annual general meeting of shareholders, upon which the shareholders eligible for dividends and the dividend amount were confirmed. We will strive to enhance the predictability of dividends for our shareholders in the future. Detailed Principle 1-⑤ Shareholders’ rights to dividends Pursuant to Article 14 of the KEPCO Act, KEPCO may pay dividends only when profit is generated as a result of the settlement of accounts for a fiscal year. Accordingly, KEPCO was unable to pay dividends for fiscal year 2023 due to a net loss. Although financial conditions remained challenging in fiscal years 2024 and 2025 due to high debt-to-equity ratios (619% in fiscal year 2024 and 444% in fiscal year 2025), despite a return to profitability, KEPCO paid dividends at the maximum level possible within the range that would allow it to secure future financial soundness, in order to respect shareholders’ rights to receive an appropriate level of return on KEPCO’s profits. As a listed public company, KEPCO implements shareholder returns. Although KEPCO has not paid any dividend for the fiscal year 2023 due to deficits, KEPCO is striving to pay a dividend and faithfully provide information on past dividends to shareholders. The distributable profit for 2024 and 2025 includes net income based on the separate financial statements.

Fair and Equitable Treatment of Shareholders Detailed Principle 2-① Issued Shares and Disclosure of Company Information Currently, KEPCO’s authorized share capital is as follows. Authorized Shares Issued Shares IssuedRate Note Common Shares 1,200,000,000 641,964,077 53.50 % Registered Common Shares Class Shares 150,000,000 — 0.00 % Non-Voting Preferred Shares * Par value of a share is KRW 5,000. * Issuance rate is the percentage of the issued shares to the authorized shares. Issued common shares are all registered common shares, and each share shall have one voting right. The voting rights of the shareholders who hold shares in excess of three percent of the total number of issued shares are limited to three percent when it comes to the agenda of election of members of the Audit Committee, under the Korean Commercial Act. KEPCO makes its company information public through its corporate website and electronic disclosure systems (DART, KIND) in order to provide information in a fair, equitable and timely manner. KEPCO holds IR meetings in relation to quarterly earnings releases in February, May, August and November. Moreover, following the relocation of its headquarters to Naju City, KEPCO holds weekly IR meetings in Seoul and conference calls with institutional investors. KEPCO announces its earnings release schedule via DART as well as public filings on the SEC website; KEPCO also posts its IR schedule on its corporate website. IR presentations are available on its corporate website, both in Korean and English. (http://home.kepco.co.kr/kepco/EN) Since listing its American Depositary Receipts on the New York Stock Exchange in October 1994, KEPCO has made English disclosures available on the SEC website through the Electronic Data Gathering, Analysis and Retrieval (“EDGAR”) system. The English filings KEPCO makes with the SEC are available by accessing http://www.sec.gov, clicking the “Company Filings” button and entering “Korea Electric Power Corporation” in the “Company Name” search field. Detailed Principle 2-② Related Party Transactions and the Internal Monitoring System KEPCO has put into effect several internal regulations, including the Code of Conduct and Conduct Guidelines for its executives and employees, so as to prevent related party transactions and self-dealings that promote private interests among its executives and employees. Also, KEPCO has established an internal monitoring system to identify and appropriately disclose related party transactions between KEPCO and its related parties. Under the Code of Conduct, employees who harm the proper performance of their duties become subject to disciplinary actions. The Code of Conduct also prohibits employees from engaging in transactions based on information obtained during the course of their employment. In addition, under the Regulations Concerning Public Disclosure, its executives and employees are prohibited from using any material non-public information related to its business in trading of securities or any other transaction. Detailed Principle 2-③ Shareholder Protection Policy To protect shareholder rights, KEPCO provides various channels to communicate with shareholders, such as its corporate website, through which shareholders may submit opinions and obtain material information on its major business and operations. There were no material changes in corporate governance structure or major business from January 2025 to June 2026, including mergers, business transfers, divestitures, exchanges or transfers of its shares. IV. Board of Directors Core Principle 3.

In accordance with the Regulations Concerning the Board of Directors, the Board of Directors may delegate to the CEO the authority to decide matters that are subject to Board of Directors resolutions to the extent that such matters are deemed to be insignificant. In addition, under the Regulations, the CEO may act on urgent matters first and then promptly request for ratification by the Board of Directors to the extent that time did not permit holding a Board of Directors meeting or the Board of Directors meeting otherwise could not be held. However, if the Board of Directors decides not to ratify the emergency measures undertaken by the CEO, such measures will have no further force and effect. Detailed Principle 3-② Succession policy for CEO The President of KEPCO, who concurrently serves as Chief Executive Officer, is appointed in accordance with the Guidelines for Personnel Management of Public Institutions and Regulations Concerning Operations of the Director Nomination Committee. The CEO is appointed by the President of the Republic of Korea upon motion by the Ministry of Climate, Energy and Environment following the nomination by the Director Nomination Committee, the review and resolution of the Committee for Management of Public Institutions (established under the Ministry of Finance and Economy) pursuant to the Act on the Management of Public Institutions and approval at the general meeting of shareholders. The CEO Nomination Committee consists of five to fifteen members with a majority of non-standing directors, and the chairperson of the committee must be selected from among non-standing directors. The CEO Nomination Committee recommends eligible candidates that meet the criteria stipulated in the Guidelines for Personnel Management of Public Institutions and Regulations Concerning Operations of the Director Nomination Committee. The eligibility criteria for a CEO candidate are as follows: • Professional knowledge and experience regarding the electric power industry; • Competence in managing organizational and corporate affairs; • Commitment and competence to initiate reform; • Strategy and vision as the Chief Executive Officer; and • Integrity, morality and a strong sense of corporate ethics. The term of the President & CEO is three years in accordance with the Act on the Management of Public Institutions.

Detailed Principle 3-③ Internal Control Policy To identify and manage various types of risks, KEPCO operates a company-wide risk control system and risk governance by designating the Chief Risk Officer (CRO). The risk management departments are set up to identify, diagnose, report and respond for each type of risk. Also, KEPCO operates the following bodies independently: a Risk Deliberation Committee, which is composed of internal and external experts, external auditors and the Audit Committee under its Board of Directors. Under the Audit Committee, an independent internal audit organization has been established to effectively support an internal control system. The Risk Deliberation Committee ensures its independence and expertise by comprising a majority of external members. For financial risks, an external auditor regularly examines and evaluates financial statements and the internal control system. In addition, the ESG Committee reviews and deliberates on major reports and decisions for non-financial risks such as environmental, social and governance issues. In terms of compliance management, KEPCO designates the establishment and amendment of internal audit regulations as a matter subject to resolution by the board and operates the Code of Conduct and the Conduct Guidelines for KEPCO executives and employees. For internal accounting management, KEPCO established Regulations Concerning Internal Control over Financial Reporting and established the internal accounting control system pursuant to the Act on External Audit of Stock Companies, etc. In order to enhance the reliability of financial information and share the importance of Internal Control over Financial Reporting company-wide, KEPCO defines control activities in detail and conducts an annual evaluation of the effectiveness of its internal accounting control system. The President & CEO of KEPCO is responsible for the company’s internal accounting control system, and the Chief Financial & Strategic Planning Officer oversees the system’s accounting management and operational organization. The CEO checks the effectiveness of the company’s internal accounting control system after the end of every fiscal year and reports the results to the general meeting of shareholders, the Board of Directors, and the Audit Committee. The Audit Committee evaluates the operation of the internal accounting control system and reports the results to the Board of Directors. For disclosure management, KEPCO established the Regulations Concerning Public Disclosure and operates the disclosure organization to ensure that all information is disclosed in a fair, accurate and timely manner. The Corporate Planning Department of the headquarters handles the disclosure work and the Audit & Inspection Office checks the disclosure for accuracy and timeliness. Also, the Chief Financial & Strategic Planning Officer is responsible for establishing and maintaining the disclosure control system and the Accounting Team under Finance & Accounting Department gathers and reviews information to be disclosed from operating departments, periodically and frequently as needed. KEPCO’s internal control system is divided into “self-compliance” as a precautionary measure and “internal audit” as a post-audit measure for effective internal checks. In addition, KEPCO and its subsidiaries jointly established an internal accounting system to enhance the reliability of consolidated financial information. Core Principle 4.

We manage such details under Regulations Concerning Operations of the Director Nomination Committee. The Director Nomination Committee is convened on an ad-hoc basis depending on the need for new appointment of directors. The committee members consist of non-standing directors and others selected by the Board of Directors and must be not less than five and not more than fifteen persons, of which the Board of Directors elects less than one-half of the members. The committee members are selected by the Board of Directors from various fields, such as law, economics, academia, media and labor relations, and are required to include one person who acts as a spokesperson for KEPCO under the relevant regulations. The chairperson of the Director Nomination Committee is elected from among the committee members who are non-standing directors by the vote of the members of the Director Nomination Committee. In order to ensure transparency and fairness in the director nomination process, KEPCO strictly complies with its internal regulations and relevant laws regarding the eligibility criteria and review procedure. Moreover, KEPCO strictly verifies the eligibility criteria of each director candidate as required by the Act on the Management of Public Institutions, the Public Service Ethics Act and the Korean Commercial Act. KEPCO provides detailed information on the director appointment process to shareholders at least two weeks before the general meeting of shareholders, to thoroughly review director candidates. Also, KEPCO persistently makes efforts to reflect minority shareholders’ opinions. We do not exclude concentrated voting under the Articles of Incorporation of KEPCO. If concentrated voting is claimed by a shareholder who has more than 1% of the issued shares in a general meeting of shareholders that is subject to the appointment of more than two directors, we can adopt concentrated voting in accordance with the Korean Commercial Act. Detailed Principle 4-④ Preventing the appointment of unqualified executives In order to prevent the appointment of executives who may damage our corporate value or shareholders’ rights, we appoint our executives in accordance with the Guidelines for Personnel Management of Public Institutions. Unregistered executives are selected from applicants who have successfully completed KEPC
