Item 2-2: Increase Audit Committee Members to be Separately Appointed Currently, the Board's Audit Committee is comprised of 3 outside directors. Pursuant to the existing Commercial Act (Article 542-12), at least 1 member of the Audit Committee is to be selected in a separate election from that of other directors and by a resolution of the General Meeting of Shareholders. The 2025 Commercial Act amendment (effective Sept. 10, 2026) expands the number of Audit Committee members mandated to large listed companies to be appointed in a separate election process from one to two. To be compliant with the revised Act, the Company resolves to increase the number of Audit Committee memebers to be appointed in an election separated from that of other directors to two(2) in our Articles of Incorporation (AOI). This amendment of the AOI duly reflects the legislative intent to enhance the independence of the Audit Committee and protect the rights and interest of minority shareholders and ensures unhindered transition to the updated governance scheme. At the upcoming Ordinary General Meeting of Shareholders, we plan to hold a separate election to appoint as members of the Audit Committee Mr. Sung-wook Park (current Audit Committee member, appointed in a separate election in Mar. '24, for a 3-year term) and one other director, thereby taking early steps to put into practice the revised Audit Committee governance scheme, as intended by the amended Act. Before Amendment Article 48. Constitution and Appointment of Members of Audit Committee (1) The Audit Committee of the Company shall consist of three (3) or more Directors. All of the members shall be elected from among the Outside Directors. New Addenda After Amendment Article 48 (Constitution and Appointment of Members of Audit Committee) (1) The Audit Committee of the Company shall consist of three (3) or more Directors, all of whom shall be Independent Directors. After Directors are elected at a General Meeting of Shareholders, the Company shall appoint the members of the Audit Committee from among the elected Directors; provided, however, that two (2) members of the Audit Committee shall be elected in a separate electrion from that of other directors, by a resolution of the General Meeting of Shareholders to also serve on the Audit Committee. ADDENDA (March 24, 2026) Article 3 (Transitional Measures for Voting Restrictions for Election and Dismissal of Independent Directors and Audit Committee Members) The amended provisions of Articles 27, 30, 31, 35, 36, 40, and 48 shall come into force on July 23, 2026; provided, however, that the amended provision of the second sentence of Article 48, Paragraph (1) shall be effective from the date on which it is approved by the resolution at the Ordinary General Meeting of Shareholders for the 58th fiscal year. Reason AOI amendment to raise the number of Audit Committee members to be separately appointed Enforcement Date Addenda 14

Item 2-3: Expand Voting Restrictions per the Appointment/Dismissal of Audit Committee Member The 2025 amended Commercial Act enhances unity of the regulations regarding the appointment and dismissal of Audit Committee members (directors to serve on the Audit Committee) to strengthen their independence and protect minority shareholders. Hence, it restricts the voting rights of any shareholder for his/her shares that exceed 3%. For the largest shareholder, the shares owned by affiliated persons must be aggregated, a rule that applies consistently regardless of whether the candidate is an outside director. Accordingly, the Company resolves to update the '3% Rule' language in its Articles of Incorporation (AOI) to align with the legislative intent and terminology. This revision does not alter the fundamental principle of the 3% Rule but does add clarity to the scope of shares aggregation for the largest shareholder in accordance with the law. (As of now) the National Pension Service (NPS) is the only shareholder that owns more than 3% of the Company's issued shares. Moreover, because our Audit Committee is composed entirely of outside directors, this AOI revision is likely to have limited impact on the exercise of voting rights at the Company's general meetings. After Amendment Article 48 (Constitution and Appointment of Members of Audit Committee) (2) A member of the Audit Committee shall be appointed or dismissed at the General Meeting of Shareholders. When appointing or dismissing a member of the Audit Committee, a shareholder holding more than three percent (3%) of the Comp any's issued and outstanding shares with voting rights (if such shareholder is the largest shareholder, for calculating the number of shares held by the largest shareholder, his/her shares, along with those owned by his/her specially related person(s), and other person(s) specified by the Enforcement Decree of the Korean Commercial Code, shall be added up together) shall not be entitled to exercise his voting rights for that excess portion. ADDENDA (March 24, 2026) Article 3 (Transitional Measures for Voting Restrictions for Election and Dismissal of Independent Directors and Audit Committee Members) The amended provisions of Articles 27, 30, 31, 35, 36, 40, and 48 shall come into force on July 23, 2026; provided, however, that the amended provision of the second sentence of Article 48, Paragraph (1) shall be effective from the date on which it is approved by the resolution at the Ordinary General Meeting of Shareholders for the 58th fiscal year. Reason Explicit language to restrict voting beyond 3% voting shares per the appointment /dismissal of Audit Committee members Enforcement Date Addenda 15

Item 2-4: Introduce Electronic General Meeting of Shareholders (GSM) The 2025 amended Commercial Act (Articles 542-14 and 542-15) allows listed companies to hold electronic shareholder meetings concurrently with physical meetings at the designated location. For listed companies specified by Presidential Decree based on asset size among other criteria, the concurrent arrangement of electronic meetings becomes mandatory from January 1, 2027. To ensure that the governance scheme is put into seamless practice upon the effective enforcement date, the company resolves to describe clear rationale for electronic GSMs in its AOI. We also plan to update the provisions to allow electronic submission in addition to written submission of proof of proxy, thereby meeting the needs of an electronic setting of the general meetings. These revisions are made in advance of the mandatory enforcement to add convenience to shareholder participation and to build the programmatic foundation for the imminent electronic shareholder meetings. Before Amendment Article 19 (Convening of General Meeting of Shareholders) Article 23. Vote by Proxy (2) A proxy shall submit a document evidencing the power of representation to the Company before the opening of the General Meeting of Shareholders. New Addenda After Amendment Article 19 (Convening of General Meeting of Shareholders) (5) The Company shall hold General Meetings of Shareholders in a manner that allows some shareholders to participate in and vote on resolutions from remote locations by electronic means, without bein g physically present at a venue of the meeting. Article 23 (Vote by Proxy) (2) A proxy shall submit a document or an electronic document evide ncing the power of representation to the Company before the opening of the General Meeting of Shareholders. ADDENDA (March 24, 2026) Article 2 (Transitional Measures for a Venue and Method of a General Meeting of Shareholders, and Proxy Voting) The amended provisions of Article 19 and Article 23, Paragraph (2) shall come into force on January 1, 2027.

Item 2-5: Delete provision regarding separate cumulative voting Pursuant to Article 382-2 of the Commercial Act, the Company has adopted a cumulative voting system, which grants voting rights per share equivalent to the number of directors to be elected. Currently, the AOI mandates that cumulative voting be staged separately for inside and outside directors. In December 2025, the Ministry of Justice issued an executive interpretation providing that when cumulative voting is arranged, it should be applied collectively to all director candidates. Hence, to align with the interpretation and in consideration of standard practices, the Company resolves to remove the provisions regarding 'separate cumulative voting' from its AOI, thereby enhancing our legal compliance and governance. Before Amendment Article 28. Election of the Directors and Representative Directors (3) If Directors are appointed by a cumulative voting, the Inside Directors and the Independent Outside Directors are separately considered, and then, the cumulative voting shall apply to each group. New Addenda After Amendment Article 28.(Election of Directors and Representative Directors) (Delete) ADDENDA (March 24, 2026) Article 1 (Effective Date) The amended Articles of Incorporation shall be effective from the date on which they are approved by the resolution at the Ordinary General Meeting of Shareholders for the 58th fiscal year.

Outside Director Appointment Process To ensure independence and transparency in the Outside Director (OD) appointment process, in 2005, the Director Candidate Recommendation Committee (DCRC) resolved to launch the Outside Director Recommendation Advisory Panel. The Panel provides the Committee with a shortlist of candidates (5 per position). The Committee then assess the qualifications of the candidates and recommends the finalists to the General Shareholders Meeting (GSM). The GSM votes on the appointment of the new Directors. —The DCRC is exclusively composed of outside directors to ensure procedural independence. —The Advisory Panel consists of five reputable senior leaders in business, finance, academia, or law. To encourage candidate nomination from shareholders, the qualifying standard for nomination has been lowered from those with equity ownership of 0.5% to 0.1%. By offering fair opportunity to responsible shareholders and strengthening shareholder engagement, we aim to ensure the effectiveness of the recommendation policy and to strengthen transparent and open governance. —POSCO HOLDINGS distributes official letters addressed by the DCRC Chair to shareholders who hold 0.1% or more in shares of POSCO HOLDINGS as of June-end of each year and posts a notice online for candidate recommendation. The letter and the notice invites the shareholder to nominate one OD candidate. —For the March 2026 GSM, official letters were sent on August 4, 2025, and call for candidate recommendation was open from August 18 to August 31, 2025. ? From 2018 to 2023, shareholders were required to hold 0.5% or more in equity ownership to recommend candidates. This requirement was changed to 0.1% in 2024 to expand shareholder participation.  To assess individual contribution of each Director, an OD evaluation policy has been introduced. By developing a guide on how to use the evaluation results, a mechanism is in place to validate and filter participation level.—OD reappointment decisions are made based on the assessment of individual contribution during the term. Outside Director (OD) Candidate Appointment Process (Aug. 12, 2025 ~ Mar. 24, 2026.) Aug. 12, 2025 Sep. 11 ~ Oct.16 Oct.28 ~ Nov.5 Feb. 19, 2026 Mar.24 Approved 'OD Candidate Recommendation Advisory Panel' Panel recommended 5 candidates per position Assessment of OD Candidates Recommendation of OD Candidates Appointment of Outside Directors (DCRC)\* (OD Recommendation (DCRC)\* (DCRC)\* (GSM) Advisory Panel) Advisory Panel) ?

Item 7 : Director Remuneration Limit A Director's compensation is comprised of the base salary and performance bonus. Funded by a defined budget approved by the GSM, the final compensation is determined based on standards prescribed by the Board and in consideration of the position and assigned role. The final performance bonus is determined by the Evaluation and Compensation Committee, exclusively composed of outside directors, that meets annually to evaluate management performance. —Assessment Standard (2025) : Quantative assessment based on consolidated financial performance is 60% (OP 15%, Revenue 10%, Operating cash flow 5%, New growth business revenue 5%, R&D expense 5%, ROA 5%, Stock price variance 15%) Qualitative assessment of effort made to enhance long-term competitiveness is 40% (ESG 10%, Business 15%, Investment/Technology 10%, Talent 5%) Total director remuneration administered as of 2025 is KRW5.9 billion; director remuneration limit for 2025 remains unchanged at KRW 10.0 billion. —Compared to 2025, in 2026, the Board will increase by 2 (1 outside director, 1 non-permanent director); however, the additions being non-permanent positions, their remuneration impact will likely be small. Category Number of Directors (Outside Directors) Upper Limit of Total Director Remuneration Total Remuneration Administered 2025 10 (6) KRW 10.0 billion KRW 5.9 billion 2026 12 (7) KRW 10.0 billion—28
