POSCO HOLDINGS generated 2025 consolidated revenue of W 69,094,886 million , down from W 72,688,143 million, and profit of W 504,403 million , down from W 947,580 million. Operating profit was W 1,827,063 million, reflecting weaker rechargeable battery materials and construction results.

For 2025, POSCO HOLDINGS approved a cash dividend of W 10,000 per share , funded at about W 756.2 billion. The plan is to pay W 2,500 per share for each of the first three quarters and W 2,500 as a year-end dividend, following its free-cash-flow-based policy.

POSCO HOLDINGS plans to rename “outside directors” as independent directors , increase separately elected Audit Committee members to two, clarify the 3% voting-right cap , allow electronic shareholder meetings from January 1, 2027, and delete provisions requiring separate cumulative voting for different director groups.

POSCO HOLDINGS intends to cancel 6% of treasury shares between 2024 and 2026, with about 4% already completed. Treasury share buybacks aimed at enhancing shareholder value are planned to be canceled, except when shares are used for employee benefit programs, reinforcing long-term capital return.

The meeting will vote on reappointing inside directors LEE Ju Tae and KIM Ki Soo , appointing new inside director CHUNG Seok Mo , non-standing director LEE Hee Geun , new outside director KIM Joo Youn , and reappointing KIM Joon Gi as an outside director serving on the Audit Committee.

POSCO HOLDINGS emphasized its HyREX low-carbon steel pilot, a new Gwangyang electric arc furnace targeted for 2026, a group-wide human rights management framework, and a strengthened safety culture, including a Group Safety Innovation TF and partnerships with global safety consultants dss+ and SGS.

POSCO HOLDINGS INC. reports 2025 results and details proposals for its 58th Ordinary General Meeting of Shareholders. Consolidated revenue was W 69,094,886 million, down from W 72,688,143 million, and profit fell to W 504,403 million from W 947,580 million as rechargeable battery materials and construction weakened.

Operating profit declined to W 1,827,063 million, while operating cash flow was W 4,570,332 million. About W 7 trillion of CAPEX focused on steel competitiveness and rechargeable battery materials. The company proposes renaming outside directors to independent directors, expanding separate elections for Audit Committee members, tightening the 3% voting cap, enabling electronic shareholder meetings from 2027, and unifying cumulative voting.

Shareholder return plans include a W 10,000 per share dividend for 2025 (fund total W 756.2 billion) and staged cancellation of 6% of treasury shares between 2024 and 2026, with 4% already completed. Multiple inside, non-standing, and outside director candidates are nominated, and the director remuneration limit for FY2026 is set at W 10.0 billion.

None.

Profit nearly halved year-on-year, with consolidated profit dropping to W 504,403 million from W 947,580 million, as rechargeable battery materials and construction operations weighed on overall performance despite some recovery in steel margins.

Profit drops sharply while POSCO hardens governance and maintains high payouts.

POSCO HOLDINGS shows a meaningful earnings setback. 2025 consolidated profit fell to W 504,403 million from W 947,580 million, as rechargeable battery materials and construction (P-E&C) underperformed despite some recovery in steel margins and substantial CAPEX around future growth areas.

Cash generation remained solid with operating cash flow of W 4,570,332 million, supporting heavy investment of around W 7 trillion in steel decarbonization, lithium, cathode materials and energy infrastructure. However, lower profitability and non‑recurring losses in construction highlight execution and cyclicality risks, especially around large projects and EV‑linked materials demand.

Governance changes are extensive: shifting to “independent director” terminology, increasing separately elected Audit Committee members to two, clarifying the 3% voting cap, enabling electronic meetings from 2027, and unifying cumulative voting. Alongside a generous W 10,000 per‑share dividend and an ongoing 6% treasury share cancellation through 2026, future filings will show how these structures influence board independence, minority protection and capital allocation discipline.

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 additional director, thereby implementing the revised Audit Committee governance scheme, as intended by the amended Act. Before Amendment After Amendment Reason 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. 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. AOI amendment to raise the number of Audit Committee members to be separately appointed New Addenda 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.

Item 2-3 : Expand Voting Restrictions per the Appointment/Dismissal of Audit Committee Members ◾ The 2025 amendment to the 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 independence and protect minority shareholders. Under the revised framework, voting rights are limited to 3% per shareholder, and for the largest shareholder, shares held by affiliated persons are aggregated regardless of whether the candidate is an outside director. ◾ Accordingly, the Company will revise ‘3% Rule’ provisions in its 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. In addition, since the Audit Committee consists entirely of outside directors, the practical impact of this revision on voting rights at general meetings is expected to be limited. Before Amendment After Amendment Reason 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 a member of the Audit Committee, a shareholder holding more than three percent (3%) of the Company’s issued and outstanding shares shall not be entitled to exercise his voting rights for that excess portion. 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 Company’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. Explicit language to restrict voting beyond 3% voting shares per the appointment /dismissal of Audit Committee members New Addenda 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.

Item 2-4 : Introduce Electronic General Meeting of Shareholders (GSM) ◾ The 2025 amendment to the Commercial Act (Articles 542-14 and 542-15) permits listed companies to hold electronic shareholder meetings concurrently with in-person 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. ◾ In preparation for smooth implementation at the effective date, the Company intends to clarify in the Articles of Incorporation the basis for convening electronic general meetings of shareholders and to revise the Articles so that documents evidencing proxy authority may be submitted in written or electronic form in a manner consistent with an electronic meeting environment. ◾ This amendment is intended to enhance shareholders’ convenience in participating in general meetings and to establish, in advance, an institutional framework for the stable operation of electronic general meetings of shareholders. Before Amendment After Amendment Reason Article 19 (Convening of General Meeting of Shareholders) 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 being physically present at a venue of the meeting. AOI amended to introduce electronic GSM 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. Article 23 (Vote by Proxy) (2) A proxy shall submit a document or an electronic document evidencing the power of representation to the Company before the opening of the General Meeting of Shareholders. New Addenda 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 equal 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. ◾ Accordingly, the Company intends to enhance the legality and compliance of the system’s operation by deleting from the Articles of Incorporation the provisions relating to the separate cumulative voting structure, reflecting the above interpretation and prevailing practice standards. Before Amendment After Amendment Reason 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. Article 28.(Election of Directors and Representative Directors) (Delete) AOI amended to introduce unified cumulative voting New Addenda 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 of the Outside Director (OD) appointment process, in 2004, 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 and law. ◾ To ease eligibility requirements and strengthen shareholder participation in the recommendation process, the Company has expanded the qualification for shareholders to recommend preliminary candidates for outside director positions from shareholders holding 0.5% or more of shares to those holding 0.1% or more. This provides responsible shareholders with fair opportunities and, through enhanced communication with shareholders, improves the effectiveness of the shareholder recommendation system as well as the transparency and openness of corporate 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 preliminary 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.
