   [000004] II. Corporate Governance Status

   [100000] 1. General Corporate Governance Policy

   1. Provide a detailed explanation of the operating direction and key considerations of the company's corporate governance policy.

      The Company believes that transparent and sound governance serves as a basis for reasonable and responsible business activities and wins th e trust of all stakeholders. The Company also believes that it forms the foundation for a sustainable enterprise that generates both economic a nd social value over the long term. As such, the Company has established and seeks to maintain a sound governance structure to not only ensu re continued stability and prosperity of its operations but also generate value for its customers, employees, and shareholders, serving as a cruc ial driver of social and economic growth and contributing to the wellbeing of broader humanity.

      The Board of Directors (the "Board") of SK hynix, the Company's highest decision making body, sets the Company's key business objectives an d basic policies while monitoring execution by top management. For the effective performance of its duties, the majority of the Company's Boa rd is comprised of independent directors with diverse backgrounds and areas of expertise. Such independent directors utilize their professiona l knowledge to review the procedural and actual legitimacy of various business activities including management decisions, thereby playing a c rucial role in ensuring the soundness of the Company's operations.

   2. Describe unique characteristics of the company's governance, if any.

      1. Composition of an independent board of directors

         As of the date of submission, the Company's Board is currently composed of ten directors (two executive directors, six independent directors, a nd two other non-executive directors) with independent directors comprising more than a majority (G0%) of the Board. All independent direct ors are independent in that they have no special relationship with company management, and without the approval of the Board, no indepen dent director can effectuate for his own account or for the account of a third person any transaction which falls within the same line of busines s as the Company or become a general partner or a director of any other company whose business purposes are the same as those of the Com pany, in order to prevent conflict of interests under the Commercial Act and the Board Regulations. The Company strives to ensure that its Boar d is led by independent directors whose independence and expertise have been vetted, that the Board effectively monitors and keeps manage ment's executive rights in check, and that balance is thus maintained in the Company's operations. Meanwhile, the Company has separated th e Representative Director (CEO) and Board Chair positions and by appointing an independent director as the Board Chair, has further strength ened the Board's independence and its oversight and check and balance over management.

      2. Enhancement of the Board's Expertise

         The Company's Board includes directors with diverse backgrounds and areas of expertise, which raises the Board's professionalism and allows it to perform effective checks on management. To ensure fair representation of various stakeholders, directors are appointed among professio nals experienced in a wide range of fields, from business, financial management, accounting, banking and finance, legal, semiconductor techn ology without disproportionate concentration on a particular background. The Audit Committee is composed of four independent directors, in cluding three experts with experience in finance, accounting, or financial management. The Sustainability Committee is operated to enhance s hareholder value through ESG while considering a broader perspective that accounts for the Company's social value creation activities and the viewpoints and demands of various stakeholders. The Company also offers detailed orientation courses for newly appointed independent dire ctors to build their understanding of the Company and the broader semiconductor industry, with an aim to enhance the professionalism and c ompetitiveness of the Board as a whole. In addition, regular workshops on ICT industry trends, semiconductor insights, ESG, and other various topics are held to continuously engage Directors to contemplate and discuss current issues and management strategies pertaining to the Com pany. In particular, the Company strives to strengthen the competency of the Audit Committee by providing various forms of internal and exter nal training on auditing, including those provided by external experts.

      3. Operation of the Council of Independent Directors

         The Company operates a council of independent directors consisting only of independent directors. At the council meeting, independent direc tors review the agenda for the Board meeting in advance and discuss items to actively express their opinions, thereby ensuring greater indepe ndence and rationality in the Board's decision making process, which leads to a greater substance in the Board's operations.

      4. Enhanced management oversight through operation of diverse committees

The Company is striving to enable the Board to perform its supervision and checks and balances over management in its capacity as the top de cision making body and as part of that the Company operates expert committees. The Sustainability Committee was established in 2018 to revi ew the strategies and results in achieving the Company's sustainable management philosophy. The Compensation Committee was charged wit h expanded functions in 2021 to include HR deliberations in addition to the remuneration of Directors and management.
