| &nbsp;&nbsp;&nbsp; Give a convocation notice 4 weeks before the general meetings of shareholders (Annual General Meetings, AGM) | O | O | &nbsp;&nbsp; The convocation notice for the AGM for the current fiscal year was issued approximately four weeks prior to the meeting date. |
| &nbsp;&nbsp;&nbsp; Use an e-voting system | O | O | &nbsp;&nbsp; POSCO Holdings has provided e-voting at all regular AGM since March 2019, enabling shareholders to exercise their voting rights more conveniently. |
| &nbsp;&nbsp;&nbsp; Hold the AGM on the date other than the dates during the popular AGM period | O | O | &nbsp;&nbsp; The AGM for the current fiscal year was convened on March 20, 2025, which falls outside the popular AGM period. |
| &nbsp;&nbsp;&nbsp; Provide predictability of cash dividends | O | O | &nbsp;&nbsp; With respect to both year-end and quarterly dividends during the disclosure period, we adopted an advanced procedure in which the dividend amount is determined first, followed by the designation of the record date. This approach enhances shareholders' visibility and predictability regarding upcoming distributions. |
| &nbsp;&nbsp;&nbsp; Notify shareholders of the dividend policy and payout plans at least once a year | O | O | &nbsp;&nbsp; During the disclosure period, we provided not only official disclosures but also supplementary information—including dividend history, mid-term shareholder return policies, and treasury stock activities—through our corporate website. Additionally, we launched a dedicated DIVIDEND INFORMATION SERVICE webpage to offer shareholders comprehensive access to dividend-related information. |
| &nbsp;&nbsp;&nbsp; Established and operate a CEO succession policy | O | O | &nbsp;&nbsp; The CEO & Representative Director is appointed at the AGM based on a nomination by the CEO Candidate Recommendation Committee, which is composed entirely of outside directors and is responsible for evaluating candidates' qualifications. In December 2023, a proposal to introduce the POSCO-Style New Governance Framework was approved to further enhance impartiality and transparency in the CEO succession process. At the 57th regular AGM held in March 2025, the Articles of Incorporation were amended to strengthen the evaluation of CEO qualifications from a shareholder perspective. Under the revised provisions, if a former CEO is re-nominated for the same position, the appointment must be made by a SPECIAL RESOLUTION—rather than by an ORDINARY RESOLUTION—at the AGM.<br>Since 2017, we have maintained a key talent pool of executives and managers at various levels to systematically develop future CEO candidates. Participants undergo training focused on core leadership responsibilities and professional management capabilities, and receive external mentoring from subject-matter experts. In addition, all outside directors and the CEO participate in an annual leadership session to review and discuss the progress of CEO succession planning initiatives. |

|:---|:---|:---|
| &nbsp;&nbsp;&nbsp; Build and operate an internal control policy such as risk management | O | &nbsp;&nbsp; We classify risks under our risk management framework into two main categories: business risks—which include management strategy, finance, and Group-level operations—and non-business risks, such as those related to ESG. For compliance management, we have incorporated compliance control standards into our internal regulations and appointed a dedicated Compliance Officer to monitor the legality of business operations.<br>Moreover, POSCO HOLDINGS takes a proactive approach to internal controls. We adopted an internal accounting management system in the very first year of its introduction in Korea, and our consolidated system is subject to external audit. To ensure timely and accurate disclosure, we have also established disclosure management guidelines. Under our internal control procedures, both the head of the responsible department and the designated disclosure officer must approve all periodic reports. |
| &nbsp;&nbsp;&nbsp; The chairperson of the Board is an outside director | O | &nbsp;&nbsp; Since 2006, the roles of Chair of the Board and CEO & Representative Director have been separated. The Chair is appointed from among the outside directors by resolution of the Board. |
| &nbsp;&nbsp;&nbsp; Use a cumulative voting system | O | &nbsp;&nbsp; Cumulative voting continues to be available as a means for shareholders to exercise their voting rights. |
| &nbsp;&nbsp;&nbsp; Have a policy to prevent the appointment of a person as an executive who is accountable for harming corporate value or infringing on the shareholders' rights and interests | O | &nbsp;&nbsp; Responsible departments conduct ongoing evaluations of the executive candidate pool, focusing on candidates' expertise, leadership, and track record. Our Code of Ethics outlines our fiduciary duties to shareholders and investors. In particular, we enforce a zero-tolerance policy on bribery, embezzlement, information manipulation, and violations of sexual ethics. We have also established policies to prevent individuals who have undermined corporate value or infringed upon shareholders' rights and interests from being appointed to executive positions. |
| &nbsp;&nbsp;&nbsp; Not all Board members are of the same gender | O | &nbsp;&nbsp; As of the report submission date, our Board of Directors is gender-diverse, comprising both male and female members. |
| &nbsp;&nbsp;&nbsp; Installed an independent internal auditing department (that supports an internal audit procedure) | O | &nbsp;&nbsp; Our Corporate Audit Office is established under the Corporate Ethics Division to assist the Audit Committee in performing its audit duties as a support organization of the internal auditing bodies. Independent of top management and controlling shareholders, the Office undertakes a wide range of activities, from supporting the Audit Committee's work and operations to assessing the internal accounting management system. The results are reported directly to the Audit Committee on a regular basis. |
| &nbsp;&nbsp;&nbsp; A specialist in accounting or finance is included in internal auditing bodies | O | &nbsp;&nbsp; In accordance with the Articles of Incorporation and the Operating Rules of the Audit Committee, the Audit Committee is composed of at least three outside directors. As required under the Commercial Act, at least one member is appointed for their expertise in accounting or finance. |
| &nbsp;&nbsp;&nbsp; Internal auditing bodies hold meetings with external auditors at least once a quarter without management present | O | &nbsp;&nbsp; The external auditor reports the results of quarterly and semi-annual reviews, as well as the annual audit, to the Audit Committee at least once per quarter, in a session where management is not present.

&nbsp;&nbsp;&nbsp;**000004] II. Corporate Governance Status**

&nbsp;&nbsp;&nbsp;**[100000] 1. General Corporate Governance Policy**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Provide a detailed explanation of the operating direction and key considerations of the company's
corporate governance policy.

POSCO HOLDINGS is committed to establishing advanced corporate governance practices that enhance long-term shareholder value while promoting the rights and interests of all stakeholders in a balanced manner. Management leverages professional expertise and rational decision-making capabilities to ensure responsible business operations, while the Board of Directors—composed primarily of independent outside directors—oversees and advises management in building a GLOBAL PROFESSIONAL MANAGEMENT SYSTEM founded on robust checks and balances. Our corporate governance principles are set forth in the CORPORATE GOVERNANCE CHARTER, which has been proclaimed both internally and externally and embedded in our day-to-day operations.

More specifically, the fundamental principles of our corporate governance are reflected in the Articles of Incorporation, the Operating Rules of the Board of Directors, the Corporate Governance Charter, and other internal regulations related to governance. These documents are publicly available on our website at http://www.posco-inc.com.

------

Having pioneered the introduction of the outside director system in Korea in 1997, we have continuously strengthened our governance framework to enhance the independence and effectiveness of the Board. Since our transition to a holding company structure through a vertical spin-off in March 2022, we have taken on a more strategic role as the Group's control tower—driving the development of future business portfolios and overseeing the operations of our affiliates.

The Board is composed of members who contribute extensive knowledge and experience across the fields of environment, public service, industry, and academia (including legal and accounting). They bring diverse perspectives into our organization and help management make rational decisions from a balanced standpoint. By ensuring that a majority of Board seats are held by outside directors, management is effectively monitored and kept in check. Moreover, the Chair positions of both the Board and its Special Committees are held by outside directors to promote the central role of outside directors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Describe unique characteristics of the company's governance, if any.

The Board of Directors is the Company's permanent and highest decision-making body, vested with the authority to appoint the CEO & Representative Director of POSCO HOLDINGS. Since 2006, following the separation of the roles of Board Chair and CEO & Representative Director, the Chair has been appointed from among the outside directors by resolution of the Board.

The Director Candidate Recommendation Committee or shareholders recommend outside director candidates with expertise across diverse areas and extensive field experience, who are then appointed by resolution at the AGM. As of the report submission date, the Board is composed of 10 members, consisting of six outside directors and four inside directors.

As of March 2024, the Board oversees six Special Committees—namely, the ESG Committee, the Director Candidate Recommendation Committee, the Evaluation and Compensation Committee, the Finance Committee, the Audit Committee, and the CEO Candidate Pool Management Committee—following amendments to the Articles of Incorporation and the Operating Rules of the Board of Directors approved at the regular AGM and the Board meeting. Outside directors hold the majority of seats on all committees, and all seats on the Director Candidate Recommendation Committee, the Evaluation and Compensation Committee, the Audit Committee, and the CEO Candidate Pool Management Committee, to ensure independent decision-making. While the Director Candidate Recommendation Committee and the Audit Committee are mandated by the Commercial Act, the other four committees were established by the Board through discretionary decisions to enhance expertise, independence, and efficiency. The Finance Committee and the Audit Committee include members with backgrounds in accounting, finance, industry, and government service, while the ESG Committee includes an environmental expert.

In 2024, the Board held 10 meetings and its Special Committees convened 29 times to support decision-making on key management issues. Outside directors dedicated significant time and effort to fulfilling their responsibilities by actively participating in key Board activities, including sessions on strategy, ESG, leadership, and performance appraisals, as well as separate meetings for outside directors and operational site visits. We remain committed to fully supporting outside directors in exercising their authority and performing their roles effectively.

[201000] (Core Principle 1) Shareholders shall be able to receive sufficient and timely information, which is necessary to exercise their rights, and to exercise their rights through appropriate procedures.

&nbsp;&nbsp;&nbsp;[201100] (Sub-principle 1-1) - Companies shall provide shareholders with the sufficient amount of information about a general meeting of shareholders, including the date, venue, and agenda, well before the actual meeting date.

Briefly describe the company's compliance with the above sub-principle (**100** bytes or less).

We provide shareholders with timely convocation notice, such as 28 days in advance for the 57th AGM.

Describe the information the company has provided regarding the general meetings of shareholders (annual general meeting, AGM), including the date, venue, and agenda of those meetings convened between the start of the period subject to disclosure to the report submission date.

POSCO HOLDINGS held two AGMs between the start of the period subject to disclosure and the submission of this report. The date, venue, agenda, and other related information for each AGM were disclosed through multiple channels: the KRX disclosure systems (in both Korean and English); the DART (Data Analysis, Retrieval and Transfer) system of the Financial Supervisory Service (FSS); the EDGAR (Electronic Data Gathering, Analysis, and Retrieval) system of the US Securities and Exchange Commission (SEC); public notices posted on our website; and mailings of the depository notice and proxy card to overseas depository receipt (DR) holders. A summary of the AGMs held during this period is provided below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Based on the above, if the company has failed to provide the sufficient amount of information regarding the
general meetings of shareholders well in advance, explain the reason(s) and future plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Shortcomings and the reason(s)

-

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Future plans and additional explanations

POSCO HOLDINGS held two regular AGMs between the start of the period subject to disclosure and the submission of this report. The date and venue for each AGM were approved by a resolution of the Board of Directors held approximately six weeks prior to the meeting. A subsequent Board meeting finalized the agenda items, which were then disclosed through official filings on the KRX, the FSS DART system, and the US SEC EDGAR system, as well as announcements posted on the POSCO HOLDINGS website. Since the regular AGM held in March 2021, we have also provided English disclosures on the KRX website to enhance information accessibility for foreign shareholders.

In 2023, we abolished voting by mail to advance ESG management by reducing paper usage, through amendments to the Articles of Incorporation approved at the regular AGM. As an exceptional measure in 2024, the final shareholder notices by mail were sent for the 56th regular AGM, detailing the date, agenda items, methods of exercising voting rights, and the online broadcast schedule, to accommodate shareholders who had previously received notices by mail. In 2025, we discontinued mailing shareholder notices for the 57th regular AGM as part of our efforts to implement ESG management practices.

The convocation notices for the 56th regular AGM in 2024 and the 57th regular AGM in 2025 were issued 28 days prior to each meeting, in full compliance with the Code of Best Practices for Corporate Governance. Going forward, we will continue our efforts to provide shareholders with sufficient information 28 days in advance of the AGM.

------

[201200] (Sub-principle 1-2) - Shareholders shall be able to participate in the AGM and express their opinions to the fullest extent.

Briefly describe the company's compliance with the above sub-principle (**97** bytes or less).

We held 3 AGMs outside peak dates and encouraged proxy voting to enhance shareholder convenience.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Describe the general information regarding the exercise of the shareholders' direct or indirect voting
rights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Describe whether the company has avoided the convocation of its general meeting of shareholders during the popular dates for AGM, conducted voting in writing, solicited the voting by proxy, etc. for the last three business years.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Convocation of AGMs Outside the Peak Period

Over the past three business years, we convened three regular AGMs, all of which were scheduled outside the popular dates for AGMs, in line with our participation in the Voluntary Compliance Program for AGM Date Separation. For details on voting rights exercised at these AGMs, please refer to the table below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Written, Electronic, and Proxy Voting

Until the 55th regular AGM in 2023, we provided all shareholders with a written voting form and return envelope to allow voting by mail for those who did not attend the AGM in person. At the 55th regular AGM, voting by mail was abolished through an amendment to the Articles of Incorporation, as part of our ESG efforts to reduce paper use. In 2024, for the 56th regular AGM, we sent the final shareholder notice by mail as a transitional measure for shareholders accustomed to receiving physical documents, and encouraged them to vote electronically or by proxy. From the 57th regular AGM in 2025 onward, mailing of shareholder notices has been discontinued as part of our ESG management practices.

Electronic voting has been implemented annually since March 2019 to enhance accessibility for shareholders. Proxy voting is also supported, with proxy forms available on the company website. Since 2021, we have also provided live online broadcasts of AGMs and accepted advance questions to encourage broader shareholder participation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Describe the company's efforts to communicate with shareholders when there was an agenda item with a high
opposition rate or that was rejected, and provide the details.

No agenda items proposed at AGMs held between the beginning of the period subject to disclosure and the report submission date were rejected or recorded a high level of opposition.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. Based on the above, if the company has not taken sufficient measures to encourage shareholders to actively
participate in the decision-making process such as the general shareholders' meetings, explain the reason(s) and future plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Shortcomings and the reason(s)

-

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Future plans and additional explanations

------

As outlined in the section above titled "A. General Information on the Exercise of Shareholders' Voting Rights," POSCO HOLDINGS utilizes electronic voting and encourages proxy voting to maximize shareholder participation in AGMs. Since 2020, we have actively promoted electronic and other non-face-to-face voting methods via our company website to support shareholders unable to attend the AGM in person due to the COVID-19 pandemic. Our convocation notices also included contact details—such as an email address and phone number—for shareholder inquiries regarding attendance and voting procedures, and we responded promptly to all inquiries received.

[201300] (Sub-principle 1-3) - Companies shall provide shareholders with the opportunity to propose agenda items for the general shareholders' meetings, and allow them to ask questions and request explanations regarding the proposals during the meetings.

Briefly describe the company's compliance with the above sub-principle (**95** bytes or less).

Since 2018, we have received recommendations for outside director candidates from shareholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Describe the details about the shareholders' right to propose agenda items, in the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Does the company provide a detailed guidance on the procedures related to shareholders' proposal on its
website, etc.?

Implemented No

We do not separately provide information on shareholder proposal procedures on our website or through other channels, as these are stipulated under the Commercial Act.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Has the company established and implemented regulations on the procedures and standards for handling
shareholders' proposals?

Implemented Yes

After receiving shareholders' proposals, our procedure requires verification of whether they meet the necessary requirements. Once confirmed, they are submitted as agenda items at the AGM through a resolution of the Board. Separate from shareholders' proposals, we have introduced and operated a shareholder recommendation system since 2018 to strengthen communication with shareholders and secure a diverse pool of outside director candidates by enabling shareholders to directly participate in the process of identifying such candidates.

Four months prior to the regular AGM, the head of the Director Candidate Recommendation Committee sends a formal notice to shareholders holding 0.1% or more of the shares. At the same time, we post a notice on the company website inviting shareholders to recommend one candidate per shareholder for the position of outside director. We accept submissions in writing, either by email or post, and the shareholder-recommended candidates undergo the same qualification review by the Outside Director Candidate Advisory Committee as other candidates nominated through the committee.

------

Until the AGM in 2024, the eligibility criteria for shareholders to recommend preliminary candidates for outside director positions were aligned with the shareholding requirements for exercising shareholders' rights to make proposals under the Commercial Act. Specifically, shareholders holding no less than 0.5% of the total number of issued and outstanding shares, excluding non-voting shares, were eligible to make recommendations. However, starting with the AGM in 2025, we expanded the eligibility criteria to shareholders holding 0.1% or more. This change aims to strengthen communication with shareholders and diversify the pool of outside director candidates.

At the regular AGM held in March 2019, one preliminary candidate—a female law professor—was submitted through the shareholder nomination process. The Advisory Committee reviewed all outside director candidates, including the shareholder-recommended nominee. However, the candidate was found not to meet the requirements for the position at the time and was therefore not recommended to the Board of Directors as an outside director candidate. The relevant details were subsequently communicated to the recommending organization. For the regular AGM held in March 2025, the shareholder nomination process was conducted from November 4 to 18, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Describe the details of shareholders' proposals raised between the start of the period subject to
disclosure to the report submission date, and explain how those proposals were addressed.

There are shareholders' proposals No

No shareholder proposals were submitted between the start date of the period subject to disclosure and the report submission date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Based on the above, describe any shortcomings in the policy to facilitate the exercise of the
shareholders' right to propose agenda items. Explain the reason(s) for the shortcomings and future plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Shortcomings and the reason(s)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Future plans and additional explanations

[201400] (Sub-principle 1-4) - Companies shall prepare mid- to long-term shareholder return policies including the one related to dividends and future plans, and provide shareholders with predictability regarding dividends.

Briefly describe the company's compliance with the above sub-principle (**99** bytes or less).

Under our shareholder return policy, we set the dividend amount first, followed by the record date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Describe whether the company has established a policy on shareholder return and whether it fully informs its
shareholders of the information, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Has the company established a dividend policy and other shareholder return policies?

Established Yes

In January 2020, the Board of Directors established and announced a mid-term dividend policy to enhance transparency and predictability regarding dividends. The disclosed policy targeted a dividend payout ratio of 30%. In calculating the payout ratio, we adjusted for one-time expenses that did not involve cash outflows, based on consolidated net income attributable to controlling interests, to more accurately reflect business performance. During the mid-term dividend policy period (2020–2022), we paid cash dividends totaling KRW 2,82 trillion, resulting in a consolidated dividend payout ratio of 24.8%. In 2022, we repurchased and canceled treasury shares equivalent to 3% of total issued shares, worth KRW 567.5 billion (based on book value). This marked our largest-ever shareholder return, totaling KRW 3,383.6 billion, with a total shareholder return rate of 29.8%.

In April 2023, we announced a new three-year (2023–2025) shareholder return policy under which a basic dividend of KRW 10,000 per share will be paid, using 50–60% of separate, annual free cash flow as the funding source, with the remaining funds returned to shareholders. The policy is designed to achieve a balanced approach between enhancing shareholder value through growth and providing stable returns to shareholders through consistent dividends. In particular, by establishing shareholder return criteria based on free cash flow adjusted for investment expenditures, we aim to introduce a basic dividend framework that supports the execution of our growth strategy without delay while minimizing the risk of fluctuations in the scale of shareholder returns due to uncertainties in free cash flow.

------

During the two-year period from 2023 to 2024, we fully fulfilled our commitment to shareholders under the new shareholder return policy by paying a basic dividend of KRW 10,000 per share. Additionally, in July 2024, we announced a new share buyback policy to repurchase and cancel 6% of our outstanding shares over a three-year period, along with the purchase and immediate cancellation of KRW 100 billion worth of new shares. We have also established a policy to immediately cancel any treasury shares newly acquired in the market for the purpose of enhancing shareholder value, except for those designated for use by executives and employees.

In July 2024 and March 2025, we canceled 2% of our treasury shares in two installments in line with this policy. In July 2024, we also purchased KRW 100 billion worth of treasury shares from the market and canceled them immediately.

Additionally, through amendments to the Articles of Incorporation adopted at the 55th regular AGM in 2023 and the 57th regular AGM in 2025, we have sequentially introduced an advanced dividend procedure that determines the dividend amount first and sets the record date thereafter for both final and quarterly dividends. Going forward, we will continue to communicate transparently with shareholders regarding shareholder returns and will actively uphold shareholders' rights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) How the company deliver the information about its shareholder return policy to shareholders? Does the company
also provide the return policy material in English?

The company has notified shareholders of the policy at least once a year Yes

The material is also provided in English Yes

We promptly disclose any new establishment of shareholder return policies, resolutions to pay quarterly or final dividends, or the implementation of share buybacks and cancellations, and provide detailed information to shareholders through IR events and postings on our website. Additionally, our company website offers shareholders easy access to information on dividend policies, treasury share status, and dividend payments through dedicated pages.

In April 2023, as we announced our mid-term shareholder return policy for the next three years (2023–2025), we promptly made Korean and English disclosures through the KRX and the US SEC, while providing shareholders with detailed information through the Q1 IR event and our website. In addition, in July 2024, we announced our shareholder return policy through a KRX disclosure, which included the following details: the cancellation of approximately 6% of the total number of shares currently issued over the next three years; a plan to purchase and cancel KRW 100 billion worth of treasury shares; and the shareholder return policy of immediately canceling any treasury shares newly acquired in the future for the purpose of enhancing shareholder value, except for those designated for use by executives and employees. This information was disclosed not only through the English version of the KRX disclosure but also via the US SEC and the company's website.

Our shareholder return policies are also specified in the periodic reports (quarterly, semi-annual, and annual business reports) submitted to the FSS each quarter.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) If the company has paid out the cash dividends between the start of the period subject to disclosure to the
report submission date, did the company provide predictability regarding dividends by making dividend decisions before the dividend record date?

Reflected to the articles of incorporation Yes

Implemented Yes

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Final Dividend

Through amendments to the Articles of Incorporation adopted at the 55th regular AGM in March 2023, we have introduced an advanced dividend procedure that determines the dividend amount first and sets the record date thereafter. This allows the Board of Directors to set the dividend record date for the final dividend at a date different from the fiscal year-end. Accordingly, the Board of Directors determined and disclosed the final dividend amount for 2023 on January 31, 2024, and the dividend record date was set as February 29, 2024, thereby providing shareholders with predictability related to dividend payout.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Quarterly Dividend

At the end of 2024, the Financial Investment Services and Capital Markets Act was amended to allow the Board to set the quarterly dividend record date in the same manner as the final dividend. Accordingly, we revised the Articles of Incorporation at the 57th regular AGM held in March 2025, to amend the provisions regarding the "change in the quarterly dividend record date" to reflect the Standard Articles of Incorporation of the Korea Listed Companies Association. As a result, the dividend amount for Q1 2025 was finalized and disclosed by the Board on May 13, 2025, with the dividend record date set as May 28, 2025, thereby providing shareholders with predictability regarding dividend-related matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Based on the above, describe any shortcomings in the course of establishing the shareholder return policy and
providing related information. Explain the reason(s) for the shortcomings and future plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Shortcomings and the reason(s)

-

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Future plans and additional explanations

-

[201500] (Sub-principle 1-5) - Shareholders' rights to receive the appropriate amounts of dividends, etc. shall be respected based on the shareholder return policy and future plans.

Briefly describe the company's compliance with the above sub-principle (**94** bytes or less).

In line with our 2023 shareholder return policy, we pursue growth and ensure stable dividends.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Describe the company's recent actions on shareholder returns.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Dividend-related matters

We paid KRW 2.81 trillion in cash dividends (representing a consolidated dividend payout ratio of 24.8%) during the mid-term dividend policy period from 2020 to 2022 and retired treasury shares worth KRW 567.5 billion (3% of total shares issued, based on book value) in 2022. The total amount reached KRW 3,383.6 billion, marking a record high in shareholder returns. The total shareholder return rate was 29.8% when cash dividends and treasury share cancellations were combined.

Subsequently, we established a new three-year shareholder return policy (2023–2025) to take a balanced approach to pursuing growth for greater shareholder value while ensuring stable dividend payments. We have set shareholder return criteria based on surplus cash flow after considering investment expenses, aiming to secure growth potential through the seamless execution of our growth strategy. We have also introduced a basic dividend to minimize the risk of fluctuations in shareholder returns caused by uncertainties in free cash flow. Additionally, through amendments to the Articles of Incorporation, we have proactively introduced advanced procedures for final and quarterly dividend payments—such as determining the dividend amount first and setting the record date thereafter. We remain committed to protecting shareholder rights by maintaining transparent communication regarding shareholder returns.

------

Meanwhile, in July 2024, we announced a new share buyback policy to repurchase and immediately cancel 6.0% of our outstanding shares over a three-year period. As part of this plan, we also committed to purchasing and retiring KRW one trillion worth of new treasury shares. Under this policy, all newly acquired treasury shares is immediately canceled—except those designated for use by executives and employees—thereby enhancing shareholder value. In line with this approach, we retired 2.0% of its treasury shares in two tranches in July 2024 and March 2025, and purchased and immediately retired KRW 100 billion in July 2024.

Maximizing shareholder value is our key corporate value and is recognized by all members of management as an overarching goal. With this in mind, we disclosed a plan to enhance corporate value in December 2024 to actively participate in the government-led corporate value-up program. With goals and action plans to enhance our corporate value, we are actively exploring ways to make use of treasury shares, including its cancellation, while closely communicating with the market regarding additional shareholder return initiatives.

In line with our new mid-term shareholder return policy (2023–2025), we paid cash dividends totaling KRW 758.8 billion in 2023 (representing a consolidated dividend payout ratio of 44.7%, KRW 10,000 per share) and KRW 757.5 billion in 2024 (69.2%, KRW 10,000), respectively.

The specifics of the cash dividends by year are illustrated in the table below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Has the company taken any action regarding shareholder returns other than dividends? If so, describe it.

In August 2022, we implemented a shareholder return program by repurchasing and canceling our own shares (3% of issued shares, equivalent to KRW 567.5 billion based on book value) to enhance shareholder value.

In July 2024, we announced a new treasury stock policy to repurchase and immediately cancel 6% of our treasury shares over a three-year period, along with the purchase and immediate cancellation of new treasury shares worth KRW 100 billion. We also established a policy to immediately cancel any newly acquired treasury shares for the purpose of enhancing shareholder value, except for those designated for executives and employees.

------

In July 2024 and March 2025, 2% of our treasury shares were canceled in two installments in accordance with this policy. Additionally, in July 2024, we purchased KRW 100 billion worth of treasury shares from the market and canceled them immediately.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Based on the above, describe any shortcomings regarding the shareholders' rights to receive an

for different classes of shares.

We have not issued any different classes of shares to date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Based on the above, explain the reason(s) and future plans if the voting rights are not fairly granted to
shareholders based on the type and number of shares they hold.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Shortcomings and the reason(s)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Future plans and additional explanations

The principle of "equitable treatment of shareholders" is publicly articulated in the POSCO HOLDINGS Corporate Governance Charter, as outlined below:

**POSCO HOLDINGS Corporate Governance Charter** 

&nbsp;&nbsp;&nbsp;&nbsp;**II. Shareholders** 

**2-2. Equitable Treatment of Shareholders** 

① Shareholder shall be fairly treated according to the type and amount of shares possessed, and the intrinsic
rights of the shareholder shall not be infringed upon.

② In any of its business dealings, POSCO HOLDINGS shall not provide special treatment for the reason of being a
shareholder and shall not take unfair action for the reason of not being a shareholder.

③ The exercise of minority shareholder rights shall be guaranteed to the extent permitted by relevant laws,
unless exercising such rights infringes the rights of all other shareholders. POSCO HOLDINGS shall seek ways (e.g., adopting the cumulative voting policy) to protect minority shareholder rights such as adopting the Cumulative Voting Policy.

Accordingly, we comply with relevant laws and internal regulations and endeavor to ensure the fair exercise of rights by all shareholders, as well as to provide them with corporate information in a timely, sufficient, and fair manner.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. Describe the details of the overall information on communications the company had with shareholders between the
start of the period subject to disclosure to the report submission date, in the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Details on major investor relations (IR) events, conference calls, and conversations with shareholders
including institutional investors.

In January, April, July, and October every year, we hold annual and quarterly earnings releases in the form of conference calls led by the CSO. These are followed by regular non-deal roadshows (NDRs) for institutional investors in Korea and Asia. We also frequently participate in conferences hosted by securities firms in Korea and abroad to directly address investors' areas of interest and to heed their requests regarding the company.

Furthermore, we provide key stakeholders with access to top management to enhance market confidence in our core business strategies. Our CSO, outside directors, and executives, including the head of the IR Team, attend overseas NDRs in person to share our performance and mid- to long-term strategic directions with investors, and to provide feedback on shareholders' areas of interest at a higher level.

We have made the email address of our IR Team available on our company website at https://www.posco-inc.com. Shareholders may submit opinions or inquiries to the IR Team through this email address. The IR Team reviews and responds to all shareholder inquiries received via email. Shareholders can also call the company's main phone number posted on the company website to reach the dedicated IR phone line, and we strive to enhance communication with minority shareholders by providing telephone responses to their inquiries.

Moreover, we established a system for investors and others who wish to visit us in person to request IR meetings through our official website. We accommodate such meetings on an as-needed basis and engage in a wide array of IR activities to reflect investors' understanding and areas of interest.

We reach out to investors in Korea and abroad through in-person meetings as well as conference calls, and strive to broaden our investor pool. In light of ESG and other emerging issues, we proactively participate in ESG NDRs, Value Day events, and conferences to enhance investor communications.

We have also live-streamed earnings releases on our company website to enhance our investor communication channels, providing minority shareholders with real-time access to such information. In March 2023, we opened a YouTube channel, POSCO HOLDINGS IR, to cater to and strengthen communication with retail investors. Our channel features video content, including Tech Talk and Market Talk led by rechargeable battery specialists, and serves to offer an overview of our rechargeable battery materials business and market interests, as well as Virtual Tour content elaborating on the key new businesses we are pursuing in Korea and overseas. As of May 2025, a total of 199 videos had been uploaded, with 26,000 subscribers and 31 million views.

The company has been designated as an unfaithful disclosure corporation No

Having consistently met our disclosure obligations, we have never been designated as a company in breach of disclosure requirements.

We have actively worked to enhance market communication, disclosing information on major issues concerning the company in both Korean and English, based on a solid understanding of and compliance with relevant laws and regulations, including those governing capital markets and disclosure. Since the incorporation of POSCO HOLDINGS in 2022, we have established disclosure standards applicable to both the holding company and its operating companies under the holding company governance structure, and implemented a system for strengthened pre-review of ad hoc disclosure items. We have also promoted disclosure awareness across the Group by providing regular training to relevant departments and sharing updates on IR best practices and global regulatory trends. In recognition of these efforts, the KRX named us a 2024 Excellence Company in Securities Markets Disclosure.

shortcomings to provide shareholders with the sufficient amount of corporate information at the right time, in a fair manner.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Shortcomings and the reason(s)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Future plans and additional explanations

As described in the above section, "C. Overall information on communications the company had with shareholders," we provide all shareholders with corporate information, including IR materials, in a timely and fair manner through our company website; DART (http://dart.fss.or.kr), the electronic disclosure system operated by the Financial Supervisory Service; KIND (http://kind.krx.co.kr), the disclosure system operated by the KRX; and other disclosure platforms.

[202200] (Sub-principle 2-2) – Companies shall establish and operate a system to protect shareholders from unfair internal transactions and self-dealing by other shareholders such as controlling shareholders.

Briefly describe the company's compliance with the above sub-principle (**99** bytes or less).

Our mechanisms protect shareholders from internal transactions and self-dealing by related parties.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Describe in detail the company's controlling measures (control policies) regarding internal transactions
with affiliated companies, etc. and self-dealing with management or controlling shareholders, etc.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Overall control policies for internal transactions and self-dealings.

Implemented Yes

We are developing a separate set of internal control regulations to establish mechanisms that prevent internal transactions by management or controlling shareholders for personal gain. Under this framework, the Internal Accounting Management Regulations stipulate that transactions involving the company's largest shareholder (including related parties) or other related parties that exceed certain thresholds must be approved by the Board of Directors.

Furthermore, we established the ESG Committee as an internal transaction deliberation body with authority equivalent to that of the Board under the Commercial Act. The Committee deliberates and decides on internal transactions involving funds, assets, and securities valued between KRW 10 billion and 200 billion. Transactions exceeding KRW 200 billion require preliminary deliberation by the Committee as well as final approval by the Board. For details on internal transactions reviewed by the ESG Committee, please refer to the "ESG Committee Meetings Held" section under Sub-principle 8-2 of this report.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Has the company have any comprehensive Board resolutions regarding internal transactions with affiliated
companies, etc., and self-dealings with management or controlling shareholders, etc.? If so, describe the details and the reason.

Pursuant to Article 542-9 of the Commercial Act, the Board of Directors grants prior approval through a comprehensive resolution for any anticipated transactions with affiliates during the current fiscal year that are expected to amount to 5% or more of total assets or total sales as of the end of the preceding fiscal year. In 2024, no such resolutions were adopted by the Board.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Details on transactions with stakeholders such as controlling shareholders.

------

In 2024, we did not engage in any transactions with major shareholders involving credit extensions, asset transfers, or business dealings. Key transactions between POSCO HOLDINGS and related parties (affiliates) are presented in the table below:

[202300] (Sub-principle 2-3) – Companies shall fully explain to shareholders any changes in their ownership structure, principal businesses, and capital raising policies that have differing interests among shareholders and take measures to protect shareholders, such as collecting minority shareholders' opinions and protecting the rights of dissenting shareholders.

Briefly describe the company's compliance with the above sub-principle (**99** bytes or less).

We protect shareholder rights by following the laws, regulations, and Corporate Governance Charter.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Describe the company's policies to protect shareholders, including how it collects minority
shareholders' opinions on mergers, business transfers, spin-offs, comprehensive exchanges and transfers of shares that caused material changes in the ownership structure or principal businesses of the company, and how it protects the right of
dissenting shareholders.

The policies are in place Yes

Based on our Corporate Governance Charter, we implement policies to fully safeguard shareholder rights in matters that could give rise to significant changes to shareholder rights or the company's continued existence—such as mergers, amendments to the Articles of Incorporation, or capital reductions. We are committed to protecting shareholder rights by actively collecting input from shareholders—including minority shareholders—via our website, main telephone line, and other available communication channels.

**POSCO HOLDINGS Corporate Governance Charter** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; II. Shareholders<br>1. Shareholder Rights<br>① Shareholders, as owners of POSCO HOLDINGS, possess the rights, including the following, which are guaranteed by relevant laws and regulations such as the Commercial Act :<br>- Right to participate in profit sharing<br>- Right to attend and vote at the AGM<br>- Right to propose objectives of the AGM, such as nomination of Director candidates<br>- Right to obtain relevant corporate information regularly and in a timely manner<br>② To protect the utmost rights of shareholders, any matters causing fundamental changes to the existence of the Company and the shareholders' rights (including mergers, amendments to the articles of incorporation, capital reduction and etc.) shall be decided at the AGM.<br>③ Shareholders should be able to exercise their voting rights as easily as possible and based on their free will. POSCO HOLDINGS will provide sufficient information on the AGM agenda and ensure that the shareholders exercise their voting rights in a written form.<br>2. Equitable Treatment of Shareholders<br>① Shareholder shall be fairly treated according to the type and amount of shares possessed, and the intrinsic rights of the shareholder shall not be infringed upon.<br>② In any of its business dealings, POSCO HOLDINGS shall not provide special treatment for the reason of being a shareholder and shall not take unfair action for the reason of not being a shareholder.<br>③ The exercise of minority shareholder rights shall be guaranteed to the extent permitted by relevant laws, unless exercising such rights infringes the rights of all other shareholders. POSCO HOLDINGS shall seek ways (e.g., adopting the cumulative voting policy) to protect minority shareholder rights such as adopting the Cumulative Voting Policy.<br>3. Responsibility of Shareholders<br>① Shareholders shall make every effort to exercise their voting rights proactively for the development of the Company, with acknowledgement of the fact that exercising such rights can affect the management of the Company.<br>② Controlling shareholder shall act in the best interests of the Company and all shareholders, and shall not inflict losses on other shareholders by acting in ways that violate this principle.<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. If there was a merger, business transfer, spin-off, comprehensive
exchange or transfer of shares, etc. during the period subject to disclosure that caused a material change in the ownership structure or principal businesses of the company, or if there is any specific plan, describe the measures taken to protect
shareholders, such as collecting minority shareholders' opinions and protecting the right of dissenting shareholders.

------

Planned No

There were no mergers, business transfers, spin-offs, or comprehensive exchanges or transfers of shares during the period subject to disclosure that could have resulted in a material change to our ownership structure or principal businesses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. Describe any capital raisings that can be converted into stock, if any, including the following:

Issued No <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Describe the issuance status of bonds, etc., that can be converted to stocks.

Through a resolution adopted by the Board of Directors in August 2021, POSCO HOLDINGS issued five-year convertible bonds totaling EUR 1,065,900,000 (approximately KRW 1.4 trillion, based on the KRW/EUR exchange rate of 1,360.32 announced by Seoul Money Brokerage Services) to fund investments in its rechargeable battery materials business. The bonds include a put option for bondholders and a call option for the issuer, allowing for early redemption.

Bondholders may exercise the put option either on the third anniversary of the payment date (September 1, 2024) or in the event of a change in control or the delisting of POSCO HOLDINGS shares. The issuer may exercise the call option under the following conditions: when, during any 30 consecutive trading days between the third anniversary of the payment date (September 1, 2024) and the 30th business day before the maturity date, the closing price of the shares equals or exceeds 130% of the exchange price on at least 20 of those trading days; when the outstanding balance of the bonds falls below 10% of the total issuance, triggering a clean-up call; or when additional tax burdens arise due to changes in relevant laws or regulations.

In September 2024, EUR 1,038,800,000 of the total face value of EUR 1,065,900,000 in convertible bonds was repaid following the exercise of the put option by bondholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Has the company considered the interests of minority shareholders in its decision-making process during any
capital raising activities with different interests among shareholders within the period subject to disclosure?

During the period subject to disclosure, there were no capital-raising activities that resulted in conflicting interests among shareholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Were there any changes in controlling shareholders due to the issuance of stock-related bonds or breaches of
agreement (loss of benefit of time) during the period subject to disclosure?

No stock-related bonds were issued during the period subject to disclosure.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. Based on the above, describe any shortcomings in collecting the opinions of minority shareholders and
protecting the rights of dissenting shareholders during any changes in the ownership structure or principal businesses of the company or the process of capital raising. Explain the reason(s) and plans for improvement.

regulations, etc. If there were any additional enhancements in addition to the company's legal obligations, describe the reason(s) and their effects.

The Board, in accordance with relevant laws and regulations and the Operating Rules of the Board of Directors, makes decisions on important matters related to the management of POSCO HOLDINGS, including the establishment of the Group's management objectives and core strategies, for the benefit of the Company and its shareholders. The roles of the Board are stipulated in detail in Article 38(1) of the Articles of Incorporation and in the Operating Rules of the Board of Directors.

The Board may establish Special Committees pursuant to Articles 38 and 45 of the Articles of Incorporation and determine and delegate matters related to their authority and operations. Specific details regarding the operation of these Special Committees, with the exception of the Audit Committee, are set forth separately in the Operating Rules.

To support the effective functioning of the Board, we organize Board sessions covering strategy, ESG, leadership, and performance appraisals, which include not only the Board and its Special Committees but also directors and key unregistered executives. Additionally, we regularly hold "outside director meetings," where outside directors play an active role in setting the agenda for Board meetings.

Agenda items for deliberation are thoroughly reviewed in advance before decisions are made by the Board. When necessary, we provide prior reports to solicit feedback from Board members and actively incorporate their input into the agenda. We also regularly arrange on-site visits for Board members to key operations to deepen their understanding of our operations.

At its 4th meeting in 2025, the Board revised the Operating Rules of the Board of Directors, authorizing the CEO to issue bonds within a one-year period, subject to predefined limits on the total amount and type of bonds.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Based on the above, if the Board has failed to effectively perform its function to make management decisions
and oversee management, explain the reason(s) and future plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Shortcomings and the reason(s)

-

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Future plans and additional explanations

While no deficiencies have been identified, POSCO HOLDINGS plans to implement the following measures.

Management leverages professional expertise and sound judgment to responsibly manage POSCO HOLDINGS on behalf of shareholders. The Board of Directors, which is primarily composed of independent outside directors, plays a critical role in overseeing and advising management throughout this process. While management takes the lead in developing initial plans on key matters such as strategic direction and management plans for the Group's principal businesses, feedback from outside directors is actively incorporated through robust discussions at the Board level, including dedicated strategy sessions and meetings with outside directors.

At the Strategy Session held in April 2023, the Board addressed a range of topics, including the Group's seven major future innovation initiatives, strategies for rebuilding competitiveness in the steel business, and the implementation plan for key initiatives in the secondary battery materials business. At the ESG Session held in July 2024, the Board discussed critical ESG issues across the Group. The session included an expert lecture on global ESG trends and companies' roles and responses, strategies for managing financial KPIs in line with the EU Taxonomy, and a review of the current status of hydrogen reduction ironmaking and carbon reduction technologies. At the Strategy and Performance Review Session held in November 2024, the Board reviewed and discussed the following items: an evaluation of the Group's business portfolio and strategic direction; operational performance and mid- to long-term strategies for principal businesses; a proposal for selecting new business domains; and the 2025 consolidated management plan.

[303200] (Sub-principle 3-2) - The Board shall establish and operate a CEO succession policy and continuously improve and supplement it.

Briefly describe the company's compliance with the above sub-principle (**99** bytes or less).

The BOD sets CEO succession policy and the Recommendation Committee consists of outside directors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Describe a CEO succession policy, if one is in place, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) The entity that established and operates the succession policy

A succession policy is in place Yes

Pursuant to Article 29 of the Articles of Incorporation governing the appointment of the CEO & Representative Director, the CEO Candidate Recommendation Committee—composed exclusively of outside directors—assesses the qualifications of candidates, and the Board of Directors nominates the final candidate to the AGM. The candidate is appointed as an inside director at the AGM and is subsequently appointed as the CEO & Representative Director by the Board, thereby completing the CEO succession process.

In December 2023, the Board approved a draft proposal to establish "POSCO-style Governance," developed with the support of external consulting, to further enhance the transparency and fairness of the CEO appointment process. This included abolishing priority reviews for the reappointment of the incumbent CEO and introducing a policy whereby the CEO appointment process begins three months prior to the end of the incumbent's tenure, regardless of any expression of intent to seek reappointment.

------

In addition, from the perspective of shareholder rights protection, we amended the Articles of Incorporation at the 57th regular AGM held in March 2025 to strengthen the qualification requirements for key executive appointments. Specifically, the resolution requirement for appointing an inside director at the AGM was raised from an ORDINARY RESOLUTION to a SPECIAL RESOLUTION in cases where the candidate for inside director is being reappointed as CEO & Representative Director after having previously served in the same role.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Main content of the succession policy including the selection, management, training of candidates (pool), etc.

Candidates were selected Yes

To ensure independence and transparency in the CEO appointment process, the Board of Directors is responsible for establishing the overarching policies and procedures governing management succession.

The CEO Candidate Recommendation Committee—established by a Board resolution and composed entirely of outside directors—is tasked with identifying prospective CEO candidates, developing detailed evaluation criteria based on the Board's defined qualifications, and conducting comprehensive, multi-dimensional assessments of each candidate's suitability.

The candidate pool identified by the Committee is further reviewed by the Outside Director Recommendation Advisor Panel, an advisory body composed of respected external opinion leaders, which was introduced to provide objective evaluations of candidate qualifications. The Committee incorporates the Panel's assessments into its final evaluation.

To further enhance transparency, the qualifications required of CEO candidates were clearly defined and publicly disclosed in advance of the 2024 regular AGM. These qualifications are structured around five key pillars—management competency, industry expertise, global competency, leadership, and integrity & ethics—and are supported by 12 specific criteria.

In March 2024, the Board established the CEO Candidate Pool Management Committee as a standing Special Committee dedicated to the systematic identification, development, and fair evaluation of CEO candidates. The internal pool—developed through the Company's CEO training program—and the external pool—sourced from executive search firms—are reviewed and updated to ensure a consistent and predictable succession process. The CEO candidate pooling process is conducted annually.

As of today, we have appointed two Representative Directors to ensure seamless business operations in the CEO's absence. To minimize operational disruptions in the event the CEO becomes unable to serve, our internal regulations require the Board to deliberate on the appointment of an acting CEO.

Note: In addition to regular meetings, the CEO Candidate Pool Management Committee held two roundtable sessions, on September 9, 2024 and January 22, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Training status of the candidates during the period subject to disclosure

Candidates have received training Yes

Since 2017, we have implemented a structured approach to cultivating future top management by identifying and managing key talent pools at various levels—including CEO, top management, and executive candidates. This is carried out through a continuous, year-round cycle of selection, development, and evaluation. Each year, all key candidates are reassessed; individuals demonstrating insufficient performance or potential are excluded, while new high-potential talent is added, thereby ensuring systematic cultivation of the CEO candidate pool. Once selected, candidates are assigned to critical roles that strengthen their managerial and leadership capabilities. They also receive targeted training on core business responsibilities and professional management skills, along with one-on-one mentoring from external experts.

In 2024, we offered key talent a variety of development opportunities, including CEO programs at leading universities and institutions, specialized courses in ESG, health and safety, and AI, external executive training (e.g., CTO development programs), and personalized CEO mentoring.

------

Notably, since 2022, we have been operating the Future Entrepreneurship Talent Development Program to nurture CEO candidates from a mid- to long-term perspective. This program selects talent at each level, helping them build management expertise, broaden internal and external networks, and gain insights through up-to-date theories and case studies. The program is reviewed and enhanced annually to align with evolving industry trends.

The CEO Entrepreneurial Top Talents Program (CETP) has been expanded to include more mentoring by industry leaders, consultants, and economists, aimed at deepening their management expertise and business insights for driving management innovation. The program also placed a greater emphasis on group discussions.

The Senior Executive Entrepreneurial Top Talents Program (SETP) has broadened its curriculum beyond group projects to include theme-based discussions on management strategies, technology trends, and financial management; expert mentoring; paper assignments; and follow-up review sessions focused on specific areas. These enhancements support senior executive candidates in developing the capabilities needed to lead business operations and secure new growth drivers.

The Junior Executive Entrepreneurial Top Talents Program (JETP) focuses on team-based projects in the Group's core business areas to help develop essential executive competencies. The program also includes expanded courses for management competency assessment and feedback.

Note: The Entrepreneurial Top Talents Program (ETP) comprises three tiers—CETP (CEO Entrepreneurial Program), SETP (Senior Executive Top Talents Program), and JETP (Junior Executive Top Talents Program).

Moreover, leadership sessions involving all outside directors and the CEO serve as a platform to share the outcomes of CEO candidate development efforts, ensuring a fair and seamless CEO succession process.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) Describe improvements and supplements in the CEO succession policy, if any, occurred between the start of the
period subject to disclosure to the report submission date.

At the 57th regular AGM held in March 2025, the Articles of Incorporation were amended to enhance the verification of qualifications from the shareholders' perspective. Under the revised provisions, if a candidate for inside director has already served two terms as the CEO & Representative Director and is nominated again for the same position, the resolution required for appointment at the AGM is raised from an ORDINARY RESOLUTION to a SPECIAL RESOLUTION.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Based on the above, if there is no CEO succession policy in place, or the policy has any shortcomings, explain
the reason(s) and future plans.

[303300] (Sub-principle 3-3) – The Board shall establish and operate internal control policies to appropriately manage the company's risks and continuously improve and supplement those policies.

Briefly describe the company's compliance with the above sub-principle (**95** bytes or less).

We have a risk management system to monitor and respond to risks and report results to the BOD.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Describe the company's internal control policies and explain whether they are continuously improved and
supplemented, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) To systematically detect and manage company-wide risks, does the company have any policy in place to promote
sustainable growth of the company? If so, describe the current operation status.

A company-wide risk management policy is in place: Yes

**Business Risk Management** 

Business risks are monitored by the Corporate Strategy Division, the Business Synergy Division, and the Finance & IR Division, with findings reported to the Board of Directors. The Management Strategy Office, under the Corporate Strategy Division, is responsible for overseeing group-wide strategy implementation and risk management during the investment process. The Finance & IR Division manages an internal investment review committee and monitors financial risks, including exchange rates and liquidity. Major issues identified by each division, along with key decisions related to new business investments, are first reviewed by the Finance Committee and ultimately decided by the Board of Directors. External business risks—such as industry and financial market trends, shifts in global business environments, and competitor strategies—are continuously monitored by the POSCO Research Institute. Monitoring results are regularly reported to relevant departments and shared across all group companies via the Global Information Hub (GIH).

**ESG and Other Non-Business Risk Management** 

The Management Strategy Office under the Corporate Strategy Division establishes and operates a Group-wide ESG issue response and management system to effectively address internal and external ESG risks across the POSCO Group. The Corporate Strategy Division sets criteria for identifying and assessing ESG risks that require Group-level oversight and monitors the status of such risks at each operating company on a monthly basis. Key ESG issues are reported quarterly to the GROUP ESG COUNCIL—a C-level consultative body—where appropriate improvement measures are discussed. The Corporate Ethics Division is responsible for identifying potential risks through internal audits and overseeing overseas compliance. The Corporate Audit Office, which operates under the Corporate Ethics Division, conducts quarterly reviews of the consolidated financial statements and the internal accounting management system to strengthen financial risk controls. The Audit Committee receives quarterly reports on audit results from the external auditor and holds separate sessions—without top management present—to hear the independent opinions of the external auditor, thereby enhancing the Committee's supervision of the Company's financial risks.

------

**Strengthening Risk Management in the Holding Company System** 

In 2025, the fourth year since the launch of POSCO Group's holding company structure, we redefined the direction of our Group-wide organizational operations to enhance synergies between the holding company and its operating companies and to reinforce risk management in response to increasingly uncertain business conditions. Accordingly, we integrated business risks related to management strategy, new business development, global M&A, and ESG into a single function, the Management Strategy Office within the Corporate Strategy Division. In addition, to strengthen risk management across overseas affiliates, we reorganized regional representative affiliates<sup>1)</sup> as entities under POSCO HOLDINGS and established the Australia Key Resources Research Center to secure core mineral resources and fortify the raw material supply chain.

1) Regional representative affiliates refer to POSCO-America, POSCO-Europe, POSCO-China, and POSCO-Japan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Does the company have a compliance management policy? if so, describe the current operation status.

A compliance management policy is in place Yes

In May 2012, we established and implemented compliance control standards through a resolution of the Board to verify our adherence to a compliance management policy. These standards were formalized as internal company regulations in August 2017. We appoint a legally qualified compliance officer responsible for overseeing the legality of our business operations in accordance with these standards, while also leading a broad range of compliance support initiatives. These include checklist-based self-assessments by departments and proactive risk management to ensure that organizational practices remain fully compliant. The appointment of the compliance officer and related activities are disclosed in our business reports, and the results of compliance activities are regularly reported to the Board.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Does the company have an internal accounting management policy? If so, describe the current operation status.

An internal accounting management policy is in place Yes

In early 2001, we proactively adopted an internal accounting management system when such frameworks were first introduced in Korea, and have since continued to enhance and improve it through annual self-assessments. Since FY2006, our consolidated internal accounting management system has been subject to audits by external auditors. As a company listed on the NYSE, POSCO is also subject to the Sarbanes-Oxley Act, a US corporate accounting reform law enacted in July 2002 that imposes strict penalties for accounting fraud. In alignment with this, the scope of our internal accounting management system has been extended beyond POSCO HOLDINGS to include key consolidated subsidiaries, thereby strengthening accounting oversight across the entire POSCO Group.

We comply with the Act on External Audits of Stock Companies and other relevant regulations, and operate a robust system that includes the establishment of a dedicated internal accounting management department, the formulation of policies and guidelines, development and implementation of training programs, and the incorporation of internal accounting evaluation results into personnel assessments and compensation decisions.

Each fiscal year, we evaluate the effectiveness of our consolidated internal accounting management system and report the results to the AGM, the Board, and the Audit Committee through the Representative Director. These evaluations consist of two parts: a design assessment and an operational assessment. The design assessment reviews whether control activities are appropriately structured to detect and prevent errors or irregularities that could affect financial reporting, and assesses their adequacy and completeness. The operational assessment verifies whether the control activities are executed as described and whether their implementation can be substantiated with evidence. If deficiencies are identified, they are addressed through discussions between the external auditor, the relevant department, and the personnel responsible for implementing the controls to ensure proper corrective actions are taken.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) Does the company have a disclosure information management policy? If so, describe the current operation status.

A disclosure management policy is in place Yes

We have also established disclosure information management guidelines, which are regularly communicated to relevant departments and subsidiaries. Additionally, we operate a process to assess whether information is subject to disclosure, including a preliminary review of items submitted to the Board or its Special Committees. For information deemed to require disclosure, the Disclosure Officer reviews the accuracy of the content in coordination with the relevant department and submits the results. After review and approval by both the head of the disclosure department and the person in charge of disclosure, the information is disclosed in a timely and appropriate manner. For regular disclosures such as business reports, we follow internal control procedures that include confirmation by the head of the responsible department and final approval by the executive in charge of disclosure.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) The composition of the committees of the Board, their chairpersons, the main roles of the committees, etc., as
of the report submission date.

Pursuant to Article 542-8 of the Commercial Act, listed companies with total assets of KRW two trillion or more must appoint at least three outside directors, who must also constitute a majority of the Board of Directors. Article 27 of the Articles of Incorporation of POSCO HOLDINGS stipulates that the Board shall be composed of no fewer than three and no more than 13 members, with up to eight outside directors and up to five inside directors. As of May 31, 2024, the Board consisted of six outside directors and four inside directors, satisfying the Commercial Act's requirement for a majority of outside directors. This composition allows the Board to effectively carry out its oversight responsibilities and support independent and balanced decision-making.

The Board also operates Special Committees, each of which includes a majority of outside directors and inside directors selected for their expertise and relevant experience. This structure enhances both the efficiency and the depth of deliberation within each committee. To ensure continuity and stability in Board operations, outside directors serve fixed terms as outlined below.

We also meticulously screen candidates to ensure that individuals responsible for undermining corporate value or infringing on shareholder rights and interests are not appointed as directors. Accordingly, all of our directors meet the qualifications required under Articles 382-3 and 542-8 (2) of the Commercial Act and other applicable laws and regulations. At the regular AGM held in March 2021, Yoo, Young Sook, a female environmental expert, was appointed as an outside director. At the regular AGM in March 2022, Yoo, Jin-Nyong, an expert in the development and commercialization of rechargeable batteries and advanced materials technologies, was appointed as an outside director. At the regular AGM held in March 2023, Kim, Joon Gi was appointed as an outside director for his expertise in law, international trade, and corporate governance improvement. The regular AGM held in March 2024 appointed Park, Sung Wook, as an outside director for his expertise in business management and technology development, further strengthening the diversity of the Board of Directors.

As of the report submission date, the Board comprises six outside directors and four inside directors. This composition not only demonstrates that outside directors form the majority of the Board, thereby meeting the requirements of the Commercial Act, but also enables the Board to effectively fulfill its role in overseeing the Company's business operations and supporting independent decision-making. To establish advanced corporate governance that enhances shareholder value and promotes the rights and interests of stakeholders in a balanced manner, we prioritize expertise and sound judgment in appointing inside directors while ensuring that outside directors contribute their diverse experience to assist management in making informed decisions and independently overseeing the management.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Based on the above, describe any shortcomings in the composition of the Board in terms of diverse backgrounds,
expertise, and responsibility. Explain the reason(s) for the shortcomings and future plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Shortcomings and the reason(s)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Future plans and additional explanations

As noted in section "A. Policies to Ensure the Expertise, Accountability, and Diversity of the Board of Directors and the Detailed Status of Each Member," Yoo Young Sook was appointed as an outside director in 2021 in recognition of her extensive experience as an environmental researcher at the Korea Institute of Science and Technology (KIST). Her appointment was intended to enhance the Board's ability to make informed decisions and strengthen its capacity to address ESG-related priorities, such as climate change and the transition to a low-carbon economy. She continues to play an active role in environmental initiatives both domestically and internationally, including serving as Chair of the Board at the Climate Change Center, a private-sector nonprofit organization. Yoo was reappointed as an outside director and elected Chair of the Board at the regular AGM held in March 2024, where she has made significant contributions to our ESG-related business activities and the effective operation of the Board.

------

To support the expansion of new businesses across the POSCO Group, Yoo Jin Nyoung was appointed as an outside director in 2022 for his expertise in the development and commercialization of advanced technologies, including rechargeable batteries and advanced materials. He began his career as a researcher at LG Chem's Polymer Research Institute and went on to serve as Chief Technology Officer and head of the Research Park. He now remains actively involved in technology development through his consulting and startup training business, leveraging his extensive network and deep understanding of both domestic and global technology trends to help POSCO HOLDINGS shape forward-looking innovation policies.

At the regular AGM held in March 2024, Park Sung Wook was appointed as an outside director in recognition of his expertise in business management and R&D within the manufacturing sector. He began his career as an industrial researcher at Hyundai Electronics and subsequently served as head of the Research Institute at Hynix Semiconductors, Chief Technology Officer overseeing R&D and manufacturing at SK Hynix, and ultimately chairperson of SK Hynix. Currently serving as chairperson of the Board at the National Academy of Engineering of Korea, he remains deeply engaged in advancing R&D and technological innovation. Leveraging his extensive experience and deep knowledge in business management and industrial R&D, Park provides valuable insights to the Board and contributes meaningfully to the Company's technology strategy.

Going forward, we will continue to ensure that the Board is composed of competent individuals with diverse backgrounds, expertise, and a strong sense of accountability. This will allow the Board to remain both independent and professional in navigating a broad spectrum of issues, thereby further enhancing its competitiveness.

**Board Skills Matrix** (as of the report submission date)

In line with the Board of Directors' approval in December 2023 of the proposed POSCO-style governance framework, we structured the outside directors' skills matrix into categories of common competencies and specialized competencies, providing greater detail on the required industry experience and technological expertise.

[304300] (Sub-principle 4-3) - The company shall ensure fairness and independence in the process of recommendation and appointment of directors.

Briefly describe the company's compliance with the above sub-principle (**99** bytes or less).

The Director Candidate Recommendation Committee has three outside directors to ensure independence.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Describe whether the company has established a committee for recommending candidates for inside and outside directors, etc. If so, describe the details of the committee and its activities.

A director recommendation committee, etc. is in place Yes

Percentage of outside directors among the director recommendation committee members (%) 100

POSCO HOLDINGS operates the Director Candidate Recommendation Committee to nominate outside director candidates for approval at the AGM. The Committee is primarily responsible for screening and recommending qualified outside director candidates to the AGM and conducting preliminary reviews of inside director candidates. It also undertakes prior deliberations on the appointment of members to the Board's Special Committees and the selection of Representative Directors from among inside directors, excluding the CEO & Representative Director.

Pursuant to Article 542-8 of the Commercial Act, listed companies with assets of KRW two trillion or more—including POSCO HOLDINGS—must appoint at least three outside directors, who must also constitute a majority of the Board. These companies are also required to structure their Outside Director Candidate Recommendation Advisor Panel such that outside directors form a majority. To go beyond these statutory requirements and further ensure independence, all three members of POSCO HOLDINGS' Director Candidate Recommendation Committee are outside directors. As of the report submission date, the Committee is chaired by outside director Yoo Young Sook.

Since 2004, we have maintained the Outside Director Recommendation Advisor Panel to ensure the independence and transparency of our outside director nomination process. Established by a resolution of the Director Candidate Recommendation Committee, the Panel consists of five highly respected senior figures from the fields of industry, finance, academia, and law. These individuals are selected for their sound judgment and deep understanding of corporate governance, free from external influence. The Panel submits a list of candidates equal to five times the number of director seats to be filled, from which the Committee evaluates and recommends the final nominees to the AGM for appointment.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Describe whether the company has been providing its shareholders with the sufficient amount of information
about director candidates and time for review, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Did the company provide detailed information on the director candidates in the case where the appointment of a
director was included in the agenda list of AGMs held between the start of the period subject to disclosure to the report submission date?

The Director Candidate Recommendation Committee evaluates the qualifications of outside director candidates and recommends them to the AGM in accordance with the Commercial Act—including Article 382(3) (qualifications for outside directors of corporations) and Article 542-8(2) (qualifications for outside directors of listed companies), as well as the Articles of Incorporation, specifically Article 30 (recommendation of candidates for outside directors) and Article 31 (qualifications for candidates for outside directors). To facilitate thorough shareholder review, we provide advance disclosure of each candidate's key professional background and other relevant information pertaining to their appointment. In compliance with Article 542-4 of the Commercial Act, we notify shareholders of the AGM agenda either in writing or electronically at least two weeks prior to the meeting, or through an electronic disclosure. In practice, however, we exceed this statutory requirement by disclosing the full agenda four weeks in advance, aligning with the convocation notice guidelines outlined in the Code of Best Practices for Corporate Governance. This ensures that shareholders are given sufficient time to assess the proposals in detail.

Note: (N) Newly appointed; (R) Re-appointed; (NAC) Newly appointed as an outside director and member of the Audit Committee

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) For reappointed director candidates, has the company disclosed whether and how their past activities as Board
members have been disclosed? If so, describe the disclosure method and details.

Information on activities of a reappointed included has been provided Yes

The activities of the Board of Directors, including major resolutions and the specific actions of its Special Committees, are disclosed on a regular basis through quarterly, semi-annual, and annual business reports. Appointments and reappointments of both inside and outside directors are publicly announced via press releases that outline their key experience, areas of expertise, and the rationale behind their selection. For reappointments, we provide the same level of comprehensive disclosure—including all documentation required under the Commercial Act—as we do for new appointments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. Describe whether the company adopted a cumulative voting system. Give detailed explanations on measures and
efforts the company has taken to gather opinions from minority shareholders in the process of candidate selection and appointment.

A cumulative voting system has been adopted Yes

Since 2004, POSCO HOLDINGS has adopted cumulative voting to enhance shareholders' ability to exercise their voting rights in director appointments. Under Articles 382-2 and 542-7 of the Commercial Act, when two or more directors are to be appointed at a general shareholders' meeting, shareholders holding at least one-hundredth of the total issued shares (excluding non-voting shares) may request the use of cumulative voting. Such a request must be submitted in writing or electronically at least six weeks prior to the meeting (or by the date of the previous year's meeting of shareholders if it is a regular AGM). In cumulative voting, shareholders are granted votes equal to the number of directors to be elected multiplied by the number of shares they own. These votes can be allocated freely to one or more candidates. The candidates with the highest number of votes are elected in descending order.

------

To ensure that minority shareholder voices are reflected in the nomination and appointment of directors, we accept shareholder proposals in accordance with Article 363-2 (shareholders' rights to make proposals) of the Commercial Act. Shareholders who have held at least 0.5% of issued shares for six months or more may submit proposals, including director nominations, for the AGM. These proposals must be submitted in writing or electronically no later than six months before the anniversary of the previous AGM. For example, on January 25, 2018, Dutch asset management companies APG and Robeco proposed a candidate for outside director pursuant to Articles 363-2 and 542-6(2) of the Commercial Act. However, the candidate later withdrew for personal reasons.

In addition to these statutory procedures, we introduced a shareholder recommendation system in 2018 to encourage broader participation in nominating outside director candidates. This system allows shareholders to recommend preliminary candidates even before the Outside Director Candidate Recommendation Committee is convened. Recommended candidates undergo the same qualification review process as those identified by the Outside Director Candidate Recommendation Advisor Panel and are included in the official pool of candidates. Until the 2024 AGM, the eligibility threshold for recommending outside director candidates was 0.5% of issued shares with voting rights. Starting with the 2025 AGM, the threshold has been lowered to 0.1% to promote more inclusive shareholder engagement and to diversify the pool of potential candidates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. Based on the above, describe any shortcomings in securing fairness and independence in the process of candidate
recommendation and appointment. Explain the reason(s) for the shortcomings and future plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Shortcomings and the reason(s)

-

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Future plans and additional explanations

As outlined in section "A. Describe whether the company has established a committee for recommending candidates for inside and outside directors, etc. If so, describe the details of the committee and its activities," POSCO HOLDINGS has operated the Outside Director Recommendation Advisor Panel since 2004 to ensure independence and transparency in the appointment of outside directors. The Panel, composed of five highly respected senior leaders, proposes a list of candidates amounting to five times the number of directors to be appointed. These candidates are then evaluated by the Director Candidate Recommendation Committee based on their qualifications. The Committee recommends the final candidates to the AGM, which holds the authority to make the ultimate decision on director appointments.

------

To appoint outside directors at the 2025 AGM, the Panel convened four times to identify and nominate candidates. The Director Candidate Recommendation Committee subsequently held two meetings to assess the candidates' qualifications and recommend the final nominees to the AGM, thereby ensuring a fair and independent appointment process.

[304400] (Sub-principle 4-4) – The company shall make efforts not to appoint a person who is accountable for damaging corporate value or infringing on the shareholders' rights and interests as an executive.

Briefly describe the company's compliance with the above sub-principle (**94** bytes or less).

We thoroughly assess candidates in the pool on expertise, leadership, performance, and ethics.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Describe details about the appointment of executives, including the unregistered ones, who are responsible for
damaging corporate value or infringing on the shareholders' rights and interests, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Does the company have a policy to prevent the appointment of any person as an executive who is responsible for
the impairment of corporate value or infringement of shareholders' rights and interests? Describe the policy and its content.

Implemented Yes

The Corporate Governance Charter outlines that directors must possess the qualifications necessary to enhance long-term shareholder value while ensuring a balanced consideration of stakeholder rights and interests. Furthermore, the Code of Ethics specifies that employees are bound by a fiduciary duty to investors, which encompasses the obligation to drive sustainable shareholder value creation.

------

**Corporate Governance Charter** 

 **III. Board of Directors** 

 **3-3. Qualification of Directors** 

① Directors shall possess an exemplary set of ethics, business sense, and integrity, and the ability to enhance
the long-term value of all shareholders and fairly represent the interests of all stakeholders.

③ Inside directors, as high-level managers of the corporation, shall have sufficient experience and knowledge
related to the Company's business, and shall be capable of making managerial decisions in a rational and appropriate manner.

④ Outside directors shall have sufficient knowledge and experience in the relevant field, such as finance,
economics, management, legal, accounting, etc., and shall have no material relationship with the Company and shall be able to make decisions independently from the Company and shareholders.

We place significant emphasis on executive appointments to enhance corporate value and protect shareholder rights and interests. The responsible department conducts ongoing, year-round verification of executive candidates for their expertise, leadership, and achievements, while also assessing their ethics through various methods to ensure that only outstanding individuals who meet rigorous standards are appointed as executives. Since 2019, we have conducted 360-degree assessments of executives and utilized the results as quantitative data to inform HR decisions, thereby strengthening the robustness of our verification process.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) Has the company appointed any person as an executive who has ever been indicted or found guilty in the final
judgment for embezzlement, breach of trust, or unfair trading under the Financial Investment Services and Capital Markets Act, unfair assistance or tunneling under the Fair Trade Act, or whom the Securities and Futures Commission has proposed to
dismiss for violating the accounting standards under the Act on External Audit of Stock Companies?

We established the POSCO Code of Ethics in 2003. Chapter IV of the POSCO Code of Ethics Practice Guidelines stipulates the Company's fiduciary duty to shareholders and investors, which includes the obligation to enhance shareholder value and provide investment information in a fair and transparent manner. The Code also clearly defines the roles and responsibilities of leaders and specifies that employees are subject to strict disciplinary measures, in accordance with relevant regulations, for non-compliance with the Code. In particular, a zero-tolerance policy applies to bribery, embezzlement, information manipulation, and violations of sexual ethics. Each January, all executives and employees sign a pledge to abide by the Code of Ethics. In this regard, we have never appointed any individual who has been penalized for malpractice, embezzlement, or other offenses as an executive. If incumbent executives become the subject of investigations by relevant authorities for serious business-related matters, they are immediately removed from their duties, either through termination of their delegation contract or dismissal, regardless of their remaining term.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) Has there been any shareholder derivative lawsuits filed between the start of the period subject to disclosure
to the report submission date? If so, describe it and its current status.

No shareholder derivative lawsuits were filed against the Company between the start date of the period subject to disclosure and the report submission date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Based on the above, describe any shortcomings in the company's efforts to prevent those who are
responsible for damaging corporate value or infringing on the shareholders' rights and interests from being appointed as executives. Explain the reason(s) for the shortcomings and future plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Shortcomings and the reason(s)

[305000] (Core Principle 5) Outsider directors shall be able to independently participate in important corporate management decision-making, and to supervise and support the management as board members.

[305100] (Sub-principle 5-1) – Outside directors shall not have any material interest with the company; the company shall check whether a director candidate has any interest with it at the appointment stage.

Briefly describe the company's compliance with the above sub-principle (**94** bytes or less).

We assess candidate interests early to ensure independence and fairness for outside directors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Describe any interests between the company and an outside director who is incumbent as of the report submission
date, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Has anyone of the outside directors had ever been employed by the company or its affiliated companies? If so,
describe the details.

As of the report submission date, none of the outside directors had been employed by POSCO HOLDINGS or any of its affiliates. In addition, there were no transactions between the outside directors and POSCO HOLDINGS or its invested companies during the past three fiscal years (2022–2024).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) In the past three years, have there been any transactions between the company (including its affiliates) and
the outside director, or with the corporation in which the outside director holds the largest shares? If so, describe the details.

We comply with the Commercial Act and other applicable laws when appointing outside directors, and we verify whether candidates have any interests in the Company early in the nomination process to ensure their independence and fairness in the overall operations of the Board of Directors. In this regard, we cross-check the professional backgrounds of outside director candidates and review the Company's transaction records during the appointment process to identify any bilateral transactions or contracts involving these candidates. We also examine the final candidates and any companies in which they are the largest shareholder to detect transactions or interests that could compromise their independence. As a result of these efforts, there have been no transactions over the past three years with outside directors or companies in which they are the largest shareholder that would constitute grounds for legal disqualification.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) In the past three years, have there been any transactions between the company and any corporation in which the
outside director has worked as an executive or staff member? If so, describe the details.

As stated in the above section, "2. Transactions between the company (including its affiliates) and the outside director," POSCO HOLDINGS complies with the Commercial Act and other applicable laws when appointing outside directors, and verifies whether candidates have any interests in the Company early in the nomination process to ensure their independence and fairness in the overall operations of the Board of Directors. In this regard, we cross-check the past professional backgrounds of outside director candidates and review the Company's transaction records during the appointment process to identify any bilateral transactions or contracts. For final candidates, we also verify both the individuals and the organizations with which they were previously affiliated to identify any significant transactions with or interests in the Company, thereby further enhancing the independence and fairness of the outside directors. There have been no transactions between POSCO HOLDINGS and the companies employing our outside directors that would constitute grounds for legal disqualification.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) Does the company have procedures and relevant regulations to verify the details of the aforementioned
transactions? If so, describe the details.

Implemented Yes

------

Pursuant to Articles 382 and 542-8 of the Commercial Act and our Guidelines on Outside Directors' Independence and Diversity, we conduct prior reviews to ensure that candidates who meet any disqualification criteria are not appointed as outside directors. In addition to statutory requirements, we meticulously assess candidates based on multiple criteria—such as independence, expertise, and extensive experience—to appoint individuals best suited to POSCO HOLDINGS.

As stated in the above section, "2. Transactions between the company (including its affiliates) and the outside director," we prepare a confirmation form documenting the disqualification criteria for outside directors as defined in Articles 382 and 542-8 of the Commercial Act during the candidate review process. Leveraging publicly available data on the candidates and their past transactions with the Company, we cross-check each candidate for any grounds for disqualification and exclude those determined to lack independence.

&nbsp;&nbsp;&nbsp;&nbsp;**III. Board of Directors** 

**3-3. Qualification of Directors** 

① Directors shall possess an exemplary set of ethics, business sense, and integrity, and the ability to enhance
the long-term value of all shareholders and fairly represent the interests of all stakeholders.

② Inside directors, as high-level managers of the corporation, shall have sufficient experience and knowledge
related to the Company's business, and shall be capable of making managerial decisions in a rational and appropriate manner.

③ Outside directors shall have sufficient knowledge and experience in the relevant field, such as finance,
economics, management, legal, accounting, etc., and shall have no material relationship with the Company and shall be able to make decisions independently from the Company and shareholders.

**Guidelines on the Independence and Diversity of Outside Directors** 

**Guidelines on the Independence of Outside Directors** 

• Outside directors are deemed independent when they meet the following criteria, and a comprehensive assessment
should be conducted to determine whether they have any material relationships with the Company:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• They have not been employed by the Company within the past five years.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• They have not engaged in business activities as employees of the Company's affiliates within the past three

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• None of their immediate family members have been employed by the Company or its subsidiaries as executives within
the past three years.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Neither the outside directors nor their family members have received compensation of KRW 120 million (USD

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• They have no other interests in the Company related to matters decided by the Board.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Based on the above, describe any shortcomings in the efforts to appoint outside directors who do not have
material interests with the company. Explain the reason(s) for the shortcomings and future plans.

[305200] (Sub-principle 5-2) – Outside directors shall devote sufficient time and effort to faithfully performing their duties.

Briefly describe the company's compliance with the above sub-principle (**99** bytes or less).

Outside directors attend the BOD, special committees and other meetings, and visit key operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Explain overall matters related to the job performance of outside directors, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Does the company have internal standards regarding the allowance of outside directors to hold concurrent
positions with other companies? If so, describe it.

Implemented No

POSCO HOLDINGS does not maintain separate internal standards governing outside directors' concurrent positions at other companies. However, we fully comply with the disqualification criteria for outside directors as stipulated in Article 542-8 of the Commercial Act and Article 34 of its Enforcement Decree, and we ensure that any incumbent outside director who meets any of these criteria is removed from office. In addition to the statutory disqualification criteria prescribed in the Commercial Act and its Enforcement Decree, outside directors are required to proactively notify the Board of Directors and the Company in advance of any other engagements that could materially affect their attendance or participation in Board meetings and related activities.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Describe the status of outside directors' concurrent employment with other companies as of the report
submission date.

The incumbent outside directors holding concurrent positions as of the report submission date are shown in the table below.

The end-of-term dates indicated in the table are based on straightforward calculations of the tenure of inside and outside directors from their respective dates of appointment. The actual expiry dates will correspond to the scheduled date of the regular AGM.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Future plans and additional explanations

------

While no deficiencies have been identified, POSCO HOLDINGS plans to implement the following measures.

The Director Candidate Recommendation Committee recommends outside director candidates in accordance with the Company's standards for identifying and evaluating such candidates. This process ensures that all nominees are independent and free from any disqualification criteria stipulated in the Commercial Act and the US NYSE listing standards. Candidates are also assessed for their extensive expertise, field-specific experience, strong managerial insight, and ability to devote sufficient time to fulfilling their duties as outside directors.

In 2024, the Board convened 10 times, and the Special Committees held a total of 29 meetings. Outside directors demonstrated their commitment by actively participating in key Board activities, including sessions on strategy, ESG, leadership, and performance evaluations, as well as separate meetings exclusively for outside directors and visits to operational sites. We remain committed to fully supporting outside directors in exercising their authority and fulfilling their responsibilities effectively.

[305300] (Sub-principle 5-3) - The company shall provide outside directors with the sufficient amount of information, resources, etc. that are necessary to fulfill their duties.

Briefly describe the company's compliance with the above sub-principle (**98** bytes or less).

We provide outside directors sufficient information, resources and training to serve on the Board.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Describe the company's policies to support outside directors in fulfilling their duties and their
specific operating status, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Has the company been providing outside directors with human and material resources and internal
information? Yes

The Operating Rules of the Board of Directors stipulate that the Company may seek assistance from external experts at its own expense to support outside directors in performing their duties. The Company may also cover expenses necessary for outside directors to fulfill their responsibilities, including costs related to research on work-related materials and information.

Outside directors recommended to the AGM for initial appointment are provided with information on the Company's business operations and Board activities. Those appointed at the AGM attend management briefings to deepen their understanding of the Company's business and regularly receive information necessary for their participation in Board activities.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Does the company have dedicated staff to respond to outside directors' requests for information
(materials)?

There are dedicated staff members Yes

We have established the Board of Directors Support Bureau, which is exclusively responsible for supporting outside directors in their participation in business operations and responding to their information requests. The Bureau is staffed by two senior-level personnel—the Head of the Bureau and a Team Leader—as well as one manager.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Does the company provide training necessary for outside directors to perform their duties? If so, describe it
and the current status of the training provided.

Training is provided Yes

Since 2024, POSCO HOLDINGS has organized specialized training programs and site visits to help outside directors deepen the expertise required to effectively fulfill their roles.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) Have there been any meetings attended only by outside directors convened separately from the Board meetings
that were held between the start of the period subject to disclosure to the report submission date? If so, describe the details.

Separate meetings of outside directors are convened Yes

------

To support the work of outside directors, we convene meetings attended exclusively by outside directors on a semiannual basis, pursuant to Article 24 of the Operating Rules of the Board of Directors. Additional special meetings may also be held as necessary. The table below outlines the regular and extraordinary meetings attended solely by outside directors from the beginning of 2024 through the report submission date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Based on the above, describe any shortcomings in the company's support necessary for outside directors to
fulfill their duties and provide the details. Explain the reason(s) for the shortcomings and future plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Shortcomings and the reason(s)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Future plans and additional explanations

While no deficiencies have been identified, POSCO HOLDINGS plans to implement the following measures.

We regularly provide all outside directors with management information, including business performance updates, IR materials, and legal briefings, and share relevant content through various formats such as press releases and reports on Company-related matters.

For significant investment agenda items requiring deliberation and resolution by the Board, we report the details to outside directors in advance of Board meetings to help them develop a thorough understanding of the relevant issues. Key feedback received during this preliminary reporting process is proactively incorporated into the materials submitted to the Board. In addition, we keep outside directors informed of the progress made on approved agenda items.

------

For the ESG Committee, the Finance Committee, and other Special Committees, meetings are held three to four days prior to Board meetings to ensure directors have sufficient time to review the agenda items proposed to both the Board and the respective committees. If additional information is required beyond what has been provided, separate discussions are arranged to enable committee members to conduct a comprehensive review of the matters at hand.

[306000] (Core Principle 6) To promote active performance of duties by the outside directors, their activities shall undergo fair evaluation; and the decisions on their remuneration and reappointment shall be made on the basis of the outcomes of such evaluation.

[306100] (Sub-principle 6-1) - The evaluation of outside directors shall be done based on their individual performance, and the evaluation results reflected in the decision on their reappointment.

Briefly describe the company's compliance with the above sub-principle (**90** bytes or less).

Assessment for the BOD is conducted yearly, and for individual directors starting in 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Describe whether the evaluation of individual outside directors is conducted and the results are taken into
consideration for reappointment, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Does the company evaluate outside directors individually? If so, describe the method in detail.

Outside directors are individually evaluated No

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Does the company have measures to ensure fairness in the evaluation of outside directors? If so, describe them
in detail.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Does the company reflect the evaluation results of outside directors in their re-appointment?

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Based on the above, if the company does not conduct an evaluation of outside directors or does not reflect the
evaluation results in the re-appointment decision, explain the reason(s) and future plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Shortcomings and the reason(s)

To encourage open yet constructive dialogue and maintain a spirit of collaboration within the Board of Directors, we do not conduct individual evaluations of outside directors. Instead, since 2010, we have implemented a Board of Directors appraisal program to enhance the external credibility of our corporate governance and to identify areas for improvement in Board operations. These assessments are conducted in the first quarter of each year, with the results reported to the Board in May.

Under this program, all directors evaluate the Board and its Special Committees using both quantitative ratings on a five-point scale and qualitative comments. The evaluation covers 27 items across four areas—roles, responsibilities, structure, and operations of the Board—as well as six to nine categories for each Special Committee. The results guide our efforts to enhance Board effectiveness through ongoing reporting and consultation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Future plans and additional explanations

In November 2024, we presented the Final Report on the Governance Structure Task Force to the Board meeting, during which the schedule for introducing individual evaluations of outside directors was finalized. Accordingly, we plan to establish detailed criteria and evaluation items for individual assessments by the first half of 2025, conduct a pilot evaluation by the end of 2025, and, based on the results, review the system's effectiveness and incorporate necessary improvements into the formal evaluation framework, which is scheduled for official implementation beginning in 2026.

[306200] (Sub-principle 6-2) - The remuneration of outside directors shall be determined at an appropriate level, considering their evaluation results, responsibilities, risks in performing their duties, etc.

Briefly describe the company's compliance with the above sub-principle (**96** bytes or less).

Outside director remuneration is set within the AGM-approved limit, considering various factors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Explain the remuneration of outside directors, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Describe the details of the remuneration policy for outside directors, background behind the establishment of
the policy, and the specific basis for calculating remuneration.

A remuneration policy is established for outside directors Yes

------

The director's remuneration limit is determined by a resolution of the AGM pursuant to Article 388 of the Commercial Act and Article 36 of the Articles of Incorporation, and compensation is provided within the limits approved by the AGM. Compensation for outside directors is determined based on a comprehensive review of benchmarking data from peer companies comparable in scope and size, as well as generally accepted social standards. Details of outside director compensation are disclosed in the Company's annual business reports.

-

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Future plans and additional explanations

While no deficiencies have been identified, POSCO HOLDINGS plans to implement the following measures.

Compensation for outside directors is determined at an appropriate level, taking into account the responsibilities and risks associated with their roles, as well as the time required. To promote open and critical discussions and foster collaboration within the Board of Directors, we do not conduct individual evaluations of outside directors. Instead, since 2010, we have implemented a Board of Directors evaluation system to enhance external confidence in our corporate governance and to identify areas for improvement in Board operations. The results of the annual evaluations conducted in the first quarter are reported to the Board in May.

------

Board evaluations are conducted in a format whereby all Board members assess the Board of Directors and the Special Committees to which they belong, using both quantitative (five-point scale) and qualitative (written comments) methods. The evaluation covers 27 items across four categories—Board roles and responsibilities, structure, operations, and more—as well as six to nine items for each Special Committee. The results are used to support continuous improvement through Board-level reporting and discussion.

[307000] (Core Principle 7) The Board shall be operated efficiently and rationally to ensure that the management decisions are made in the best interests of the corporation and shareholders.

[307100] (Sub-principle 7-1) – In principle, the Board shall be convened regularly, and the Board' operating regulations shall be prepared to specify its authority, responsibilities, operating procedures, etc.

------

Briefly describe the company's compliance with the above sub-principle (**97** bytes or less).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Describe the overall operation of the Board, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Does a board meeting be convened on a regular basis? If so, describe the details of the regulations related to
the operation of the Board.

Board meetings are convened on a regular basis Yes

Regulations that govern the board operation are in place Yes

The authorities, responsibilities, and operating procedures of the Board of Directors are stipulated in the Operating Rules of the Board of Directors, which are publicly available on our website.

Pursuant to Article 7 of these Rules, the Board convenes both regular and extraordinary meetings. In principle, regular meetings are held in January, February, March, May, August, November, and December, while extraordinary meetings are convened as necessary to address urgent matters.

Board meetings are convened by the Chair of the Board. Individual directors may also request the Chair to call a meeting when deemed necessary. If directors are unable to attend in person, they may participate via remote communication methods that enable real-time audio transmission. Directors participating through such means are deemed present at the meeting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Describe the information on regular and extraordinary board meetings convened between the start of the period

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Describe the policies that the company provides to assist the Board in making the best decisions, including the
following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Did the company establish the remuneration policy linked to each executive officer's performance and
disclose it?

The remuneration policy for executive officers is in place Yes

The remuneration policy is disclosed Yes

The executive compensation policy of POSCO HOLDINGS is determined by the AGM and the Board of Directors. Executive performance-based pay is linked to both individual and organizational performance, with assessments of business performance and corresponding payout ratios decided by the Evaluation and Compensation Committee—a Special Committee under the Board composed solely of outside directors—through internal deliberations conducted without the presence of management. The items reviewed by the Committee are submitted to the Board for final approval. The Company's executive compensation policy is disclosed in its annual business reports and semi-annual reports, and the relevant details are communicated in a transparent manner.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Did the company take out the Directors & Officers Liability Insurance policy?

The company took out the insurance policy Yes

POSCO HOLDINGS purchased a Directors & Officers Liability Insurance policy in February 1999, following a report to the Board of Directors, to help executives mitigate risk exposure and focus fully on their management responsibilities. Since then, the policy has been renewed on an annual basis. The insurance does not cover liabilities arising from criminal lawsuits involving charges of malpractice or other criminal conduct, in order to prevent its misuse as a means of avoiding accountability by directors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Does the company consider the interests of stakeholders that affect its continued growth and medium- to
long-term interests?

Stakeholders are taken into consideration Yes

Since 2022, POSCO HOLDINGS has hosted the Stakeholder Roundtable annually to identify stakeholders' needs and expectations and incorporate them into its business operations. The Stakeholder Roundtable is a recurring annual meeting that brings together key stakeholders—including investors, customers, and suppliers—to discuss critical issues, share the Company's current responses, and explore areas for improvement in dialogue with our executives.

The outcomes of these discussions, along with stakeholder inquiries received throughout the year and evaluations conducted by external organizations, are used as key input for our materiality assessment. The top issues identified through this process are reported to the Board of Directors, which formally designates them as "Key ESG Issues." These issues are then incorporated into our mid- to long-term KPIs and are systematically managed. Progress and improvements are disclosed on our website through our annual sustainability reports.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. Based on the above, describe any shortcomings such as a lack of the Board operating regulations that provide
the basis for convening the Board meetings on a regular basis, or a failure to notify the convocation of Board meetings sufficiently in advance. Explain the reason(s) for the shortcomings and future plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Shortcomings and the reason(s)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Future plans and additional explanations

While no deficiencies have been identified, POSCO HOLDINGS plans to implement the following measures.

POSCO HOLDINGS convenes both regular and extraordinary meetings of the Board of Directors. In principle, regular meetings are held in January, February, March, May, August, November, and December. As outlined in Sub-principle 7-1(2) of this report, we ensure that Board meetings are conducted in accordance with this established schedule.

[307200] (Sub-principle 7-2) - The Board shall keep detailed minutes of each meeting and disclose the activities of individual directors, including their attendance at meetings, whether they voted for or against each agenda item, etc.

Briefly describe the company's compliance with the above sub-principle (**96** bytes or less).

We keep minutes and disclose information on directors' attendance, voting, and other activities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Describe the creation and preservation of the records of Board meetings and disclosure of the activities of
individual directors, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Does the company create and preserve detailed minutes and transcriptions of the Board meetings? Does it have
applicable regulations regarding the creation and preservation of the records?

Implemented Yes

In accordance with Article 15 of the Operating Rules of the Board of Directors, POSCO HOLDINGS prepares minutes for all Board meetings. The original minutes are maintained by the department in charge, while copies are retained by relevant departments for a period of 10 years.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Does the company record the main content of the discussions and resolutions made at the Board meetings by each
individual director?

Implemented Yes

------

The minutes of Board meetings record the interventions of individual directors when necessary, along with the agenda items, proceedings, resolutions, and any dissenting opinions and their stated reasons. The minutes are either signed or sealed by the attending directors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Give the details about individual directors' attendance at the Board meetings and the approval rate of
each agenda item over the last three years.

The table below shows each director's attendance at Board meetings from the start of the period subject to disclosure through the report submission date, as well as their attendance rates and voting records on agenda items for the past three fiscal years.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Do outside directors make up a majority of each committee of the Board?

All committees under the Board are composed of a majority of outside directors. As of the report submission date, we operate a total of six Special Committees—namely, the ESG Committee, the Director Candidate Recommendation Committee, the Evaluation and Compensation Committee, the Finance Committee, the Audit Committee, and the CEO Candidate Pool Management Committee—which were established through amendments to the Articles of Incorporation and the Operating Rules of the Board of Directors in March 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Describe the organization and operation of the committees of the Board, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Does the company have the explicit provision on the organization, operation, and authority of the committees of
the Board? If so, describe it in detail.

The company has the express provision Yes

------

Pursuant to applicable laws, Articles 38-2 and 45 of the Articles of Incorporation set forth provisions related to Special Committees, establishing the institutional framework for delegating certain authorities of the Board of Directors to these committees. In addition, Chapter 4 of the Operating Rules of the Board of Directors outlines the procedures governing the Special Committees, including their composition, convening procedures, and notification requirements. Article 20 of the Operating Rules and the accompanying table further detail the matters to be referred to Special Committees, ensuring that decisions are made on items delegated by the Board.

In March 2024, we revised the Articles of Incorporation and the Operating Rules of the Board of Directors to restructure our Special Committees. As of the report submission date, we operate six Special Committees: the Director Candidate Recommendation Committee, the Evaluation and Compensation Committee, the Finance Committee, the Audit Committee, the ESG Committee, and the CEO Candidate Pool Management Committee. Among these, the Director Candidate Recommendation Committee and the Audit Committee are required under the Commercial Act, while the remaining four were voluntarily established by the Board to enhance its expertise, independence, and operational efficiency.

The Finance Committee and the Audit Committee include experts with backgrounds in industry and accounting/finance, while the ESG Committee includes environmental specialists. To ensure continuity of expertise within each committee, we also seek to minimize changes in committee membership during directors' terms of office. As of the report submission date, the composition, duties, and authorities of each Special Committee are as follows:

**1. ESG Committee** 

1) Composition: Three outside directors and one inside director (Head: Yoo, Jin Nyoung; Members: Yoo, Young Sook, Kim, Joon Gi, Chun, Sung Lae)

2) Roles and Responsibilities: Monitoring ESG compliance and issuing reports; conducting reviews or preliminary reviews of internal transactions in accordance with the Monopoly Regulation and Fair Trade Act; and deliberating on matters related to the operation of the Board of Directors and Special Committees.

**2. Director Candidate Recommendation Committee** 

1) Composition: Three outside directors (Head: Yoo, Young Sook; Members: Kwon, Tae-Kyun, Sohn, Sung Kyu)

2) Roles and Responsibilities: Screening the qualifications of outside director candidates; and recommending nominees to the AGM.

**3. Evaluation and Compensation Committee** 

1) Composition: Four outside directors (Head: Kim, Joon Gi; Members: Kwon, Tae-Kyun, Yoo, Jin Nyoung, Park, Sung Wook)

2) Roles and Responsibilities: Assessing management performance; and reviewing and establishing executive compensation plans.

------

**4. Finance Committee** 

1) Composition: Three outside directors and one inside director (Head: Park, Sung Wook; Members: Yoo, Jin Nyoung, Sohn, Sung Kyu, Lee, Ju Tae)

2) Roles and Responsibilities: Conducting prior deliberations and approving investment-related matters.

**5. Audit Committee** 

1) Composition: Three outside directors (Head: Sohn, Sung Kyu; Members: Kim, Joon Gi, Park, Sung Wook)

**6. CEO Candidate Pool Management Committee** 

1) Composition: All outside directors (Head: Kwon, Tae-Kyun; Members: Yoo, Young Sook, Yoo, Jin Nyoung, Sohn, Sung Kyu, Kim, Joon Gi, Park, Sung Wook)

2) Roles and Responsibilities: Conducting preliminary reviews of the basic qualifications of CEO and Representative Director candidates as determined by the Board of Directors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Are the resolutions of the committees be reported to the Board?

Reported Yes

Pursuant to Article 21 of the Operating Rules of the Board of Directors, each Special Committee is required to notify the directors of its decisions, except for those made under authority granted by applicable laws. If any director objects to a decision made by a Special Committee, the director may request that a Board meeting be convened to reconsider the matter within two business days of receiving the notice.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Describe the status of reporting the resolutions of each committee of the Board between the start of the period
subject to disclosure to the report submission date.

As of the report submission date, we operate a total of six Special Committees: the ESG Committee, the Director Candidate Recommendation Committee, the Evaluation and Compensation Committee, the Finance Committee, the Audit Committee, and the CEO Candidate Pool Management Committee. For details on the decisions made by each Special Committee and reported to the Board between the beginning of the disclosure period and the report submission date, please refer to the table below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Describe the policies for ensuring independence and expertise of the internal auditing bodies

Accounting or finance experts are included in the Committee Yes

The Audit Committee is composed entirely of outside directors, including at least one accounting or financial expert, as required by the Commercial Act. The Committee operates independently from both the Board and management to ensure objectivity in fulfilling its audit responsibilities, in compliance with all applicable laws and regulations. To further reinforce independence and expertise, we have established the Outside Director Candidate Advisory Committee—a non-board advisory body—and the Director Candidate Recommendation Committee, a Special Committee under the Board. These committees independently identify and recommend candidates, including accounting experts as required by law, from academia, industry, and the legal profession. Final appointments are made by resolution of the AGM.

------

In accordance with Article 542-11 of the Commercial Act, we are legally required to establish an Audit Committee, which has been duly constituted and is currently in operation. Accordingly, we do not separately appoint standing auditors, and the matter of standing auditors concurrently holding other positions is not applicable to our governance structure. The Audit Committee fully satisfies all statutory requirements regarding the appointment and qualifications of its members.

| &nbsp;&nbsp;&nbsp;Appointment Requirements | Compliance Status | Pertinent Laws |

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Does the company have separate regulations governing the operational objectives, organization, authority, and
responsibilities of the internal auditing bodies? If so, describe them with the details.

Regulations regarding the internal auditing bodies are in place Yes

The Audit Committee operates independently of management and controlling shareholders in accordance with the Articles of Incorporation and the Operating Rules of the Audit Committee. Pursuant to these regulations, the Committee is authorized to audit the performance of directors, including reviews of the Company's accounting records and business operations. The Committee may request directors to report on operations or may investigate the business practices and assets of the Company. In cases where directors engage in activities that violate applicable laws or the Articles of Incorporation and may cause irreparable harm to the Company, the Audit Committee is empowered to demand the suspension of such activities in the best interests of the Company. If the Committee identifies an actual or potential violation of laws or the Articles of Incorporation by a director, it is obligated to report the matter to the Board, as stipulated in the Operating Rules. Should the Audit Committee fail to perform its duties, it assumes joint and several liability to the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Does the company provide training necessary to perform the audit?

Training is provided for the auditing bodies Yes

------

Between the beginning of the disclosure period and the report submission date, training was provided to members of the Audit Committee as outlined below. In 2025, we plan to continue offering training on the establishment and revision of relevant regulations, as well as other related topics.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Does the company provide external expert advisory support to the Audit Committee? If so, describe the details
of that support.

External advisory support is provided Yes

In accordance with the Articles of Incorporation and the Operating Rules of the Audit Committee, the Committee may seek advice from external experts at the Company's expense when deemed necessary. If the external auditor notifies the Committee of any non-compliance with accounting standards by the Company, the Audit Committee may also engage external specialists, at the Company's expense, to investigate the matter. Based on the results of the investigation, the Committee may request corrective actions from the Representative Directors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) Does the company have regulations on the investigation of fraudulent acts of management, and provide necessary
information, expenses, etc. to the internal auditing bodies?

Regulations on an investigation procedure has been established Yes

Pursuant to the Operating Rules of the Audit Committee and the Articles of Incorporation, the Audit Committee is authorized to audit the overall work conducted by the Board of Directors, Representative Directors, and other relevant parties across the Company's business operations. The Company bears all expenses incurred in relation to the Committee's activities.

In accordance with the Operating Rules of the Audit Committee, the Committee may request that a director cease any action that violates laws, regulations, or the Articles of Incorporation if such action poses a risk of causing irreparable harm to the Company. The Audit Committee is also required to report to the Board of Directors any actions by a director that violate, or are deemed likely to violate, applicable laws, regulations, or the Articles of Incorporation. In addition, if the Committee receives a notification from the external auditor regarding a violation of the Company's accounting standards, it shall engage an external expert—at the Company's expense—to investigate the matter. Based on the results of the investigation, the Committee may request that the Company's Representative Director implement appropriate corrective measures.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) Does the company have procedures for the internal auditing bodies to access information relating to matters
that could significantly impact corporate management?

Procedures for the internal auditing bodies to access information are in place Yes

Article 4 of the Audit Committee Operating Regulations stipulates the Committee's authority to request business reports and to investigate the Company's operations and assets. This provision serves as the basis for the Audit Committee to request reports from directors and employees, examine the Company's business activities and assets, and seek expert advice at the Company's expense. In addition, pursuant to the Operating Regulations of the Audit Committee, the head of the Committee may request the attendance of individuals deemed necessary for the deliberation of agenda items, and those requested shall attend unless exceptional circumstances apply.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. Describe the organization that supports the internal auditing bodies, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Has the company installed an organization that supports the internal auditing bodies?

A supporting organization is in place Yes

To support the efficient execution of its audit responsibilities, the Audit Committee is assisted by the Corporate Audit Office under the Corporate Ethics Division, which serves as the support unit of the internal auditing bodies . Through this Office, the Audit Committee may access key business documents, review relevant information, and carry out other necessary procedures. As of the end of 2024, the Corporate Audit Office was composed of eight personnel: one head (executive level), one Certified Public Accountant (CPA), and six staff members. Operating independently of management and controlling shareholders, the Office supports the activities of the Audit Committee, conducts audits of consolidated financial statements and other financial and accounting records, evaluates the internal accounting management system, performs audits and provides audit support to domestic and overseas affiliates, and establishes and updates ethical management policies. To safeguard its independence from management, the Corporate Audit Office reports the results of its activities directly to the Audit Committee on a regular basis.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Does the company ensure the independence of the organization supporting the internal auditing bodies?

The independence of the supporting organization is secured Yes

The Audit Committee secures its independence from management by holding the authority to approve the appointment and dismissal of the head of the Corporate Audit Office under the Corporate Ethics Division. In November 2024, to further strengthen the independence of the support organization of the internal auditing bodies , the recruitment plan for internal audit personnel (general staff level) was reported to the Audit Committee. Furthermore, pursuant to Article 8 of the Internal Audit Guidelines, internal auditors perform their duties from an independent and objective standpoint.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. Describe whether the remuneration of Audit Committee members and auditors is commensurate with their statutory
responsibilities and is at a level that supports the faithful performance of their duties, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Does the company have an independent remuneration policy for Audit Committee members and auditors?

An independent remuneration policy is in place No

The compensation for the Audit Committee, which is composed of outside directors, is determined with full consideration of generally accepted social standards and benchmarking against companies of comparable size and scope of responsibilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Suggest the remuneration ratio between outside directors who are Audit Committee members or the auditor and
those who are not.

Remuneration ratio 1.02

While the compensation for Audit Committee members and outside directors who do not serve on the Audit Committee is, in principle, equivalent, minor differences may arise depending on the frequency of their participation in Special Committee meetings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. Based on the above, describe any shortcomings in securing the independence and expertise of the internal
auditing bodies. Explain the reason(s) for the shortcomings and future plans.

In accordance with the Articles of Incorporation and the Operating Rules, the Committee receives the balance sheet, income statement, consolidated financial statements, and business report from the Representative Director, prepares an audit report at least one week prior to the regular AGM, and submits it to the Representative Director. The Committee also reviews the agenda items and documents submitted by the directors to the AGM and provides its opinion on whether any items violate laws or the Articles of Incorporation, or are materially unreasonable.

The policies are in place Yes

There were situations that might compromise the auditor's independence No

The Securities and Futures Commission (SFC) designated EY Han Young as the external auditor of POSCO HOLDINGS for the 57th to 59th fiscal years (2024–2026), pursuant to Articles 11(1) and 11(2) of the Act on External Audits of Stock Companies, Article 17 of its Enforcement Decree, and Articles 10 and 15(1) of the Regulations on External Audits and Accounting.

------

The Audit Committee received a report on the designation process and schedule on November 6, 2023, and subsequently reviewed matters related to audit fees, timelines, and personnel on December 19, 2023, before approving the appointment of Ernst & Young Han Young as the Company's new external auditor.

To ensure the auditor's independence, all non-audit services provided by Ernst & Young Han Young are subject to prior approval by the Audit Committee (1st meeting of 2024) before any service agreements are executed. In addition, the Company does not enter into success-based fee arrangements related to financial statements or audits and fully complies with all applicable legal requirements concerning auditor qualifications and independence.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Has the company been convening meetings regarding the appointment of the external auditor? If so, describe and
the discussion points from each meeting.

The SFC designated Ernst & Young Han Young as the external auditor of POSCO HOLDINGS for the 2024–2026 period (the 57th to 59th fiscal years). On December 19, 2023, the Audit Committee convened an in-person meeting to review and approve the terms of the audit contract, taking into consideration the scope of audit work, audit timelines, personnel assignments, and the auditor's independence.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Does the company conduct an evaluation after the completion of the external audit to confirm whether the
external auditor faithfully executed the audit plan? If so, describe the details.

The Audit Committee conducts annual evaluations to determine whether the external auditor has faithfully executed the audit plan. The assessment includes a review of the auditor's independence and objectivity, the quality of audit services, and the adequacy of audit resources, including fees, time allocation, and staffing. The Committee evaluated the external auditor's performance for FY2023 at its 8th meeting in 2024. The evaluation of the auditor's performance for FY2024 is scheduled to take place at the Committee's 5th meeting in 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) If the company receives consulting or non-audit services from the
external auditor and its affiliated companies, describe the reason(s) for selecting the service provider and details of the paid cost.

To safeguard auditor independence, POSCO HOLDINGS conducts prior reviews to ensure that non-audit services provided by the external auditor or its affiliates do not impair the auditor's objectivity or independence. Additional confirmation procedures are also carried out by the auditor. Only non-audit services that are not prohibited under the Certified Public Accountant Act or other applicable laws—and that do not compromise auditor independence—are permitted. During the reporting period, we engaged the external auditor for the following non-audit services: tax advisory services (KRW 70 million) and comprehensive income tax filing services for personnel at overseas subsidiaries (KRW 22 million).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Describe the main agendas discussed with the external auditors and procedures to reflect them in their internal
audit duties, and the details.

The external auditor consults with the Audit Committee on the annual audit plan, material matters related to the Company's financial statements and overall operations in connection with the external audit, as well as issues concerning the internal accounting management system. Where appropriate, the outcomes of these consultations are reflected in internal audit activities through the support organization of the internal auditing bodies .

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Describe the process where the external auditor notifies the internal auditing bodies of any material findings
discovered during the audit. What's the role and responsibilities of the internal auditing bodies in this regard?

In accordance with the Operating Rules of the Audit Committee, the external auditor may propose agenda items to the Committee in cases involving director misconduct in the performance of duties, material violations of applicable laws or the Articles of Incorporation, or non-compliance with accounting standards by the Company.

Furthermore, the Audit Committee is obligated to report to the Board of Directors if any director has engaged in, or is likely to engage in, actions that contravene relevant laws or the Articles of Incorporation. Upon receiving notification from the external auditor regarding non-compliance with accounting standards, the Audit Committee may appoint external experts at the Company's expense to investigate the matter and may request the CEO to implement corrective measures based on the investigation's findings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) When did the company provide its financial statements to the external auditor?

Financial statements were provided at least six weeks prior to the AGM Yes

Consolidated financial statements were provided at least four weeks prior to the AGM Yes

The unaudited financial statements for 2024 were submitted to the external auditor (Ernst & Young Han Young) six weeks prior to the regular AGM, and the unaudited consolidated financial statements were submitted four weeks prior to the meeting.

Likewise, the unaudited financial statements for 2023 were submitted to the external auditor (Samjong KPMG) six weeks prior to the regular AGM, and the unaudited consolidated financial statements were submitted four weeks prior to the meeting.

Note: This disclosure may contain forward-looking statements and future plans that are subject to change due to various internal and external factors. Accordingly, actual results may differ materially from those anticipated or expressed in this document.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Describe the disclosure status of the company's Corporate Value-up Plans submitted during the past three
years. Has the Board been involved in the process of establishing and disclosing those plans?

On December 23, 2024, we submitted a disclosure titled "POSCO HOLDINGS Corporate Value-Up Plan."

The plan outlines our strategy to enhance corporate value through growth investments over the next three years, targeting a revenue CAGR of 6-8% and a ROIC of 6-9%. These goals will be achieved through efficient capital allocation, a consistent shareholder return policy, and governance innovation.

To achieve the Group's revenue growth target of 6-8%, the steel business will increase investments in high-growth, high-margin markets while strengthening product competitiveness. In the battery materials business, we will reinforce our competitiveness by securing high-quality resources in advance and driving innovation in products and process technologies. In addition, we will lay the foundation for sustainable growth by identifying and promoting new businesses aligned with group-level strategic priorities and value creation.

To improve ROIC across the Group, low-ROIC assets and businesses will be restructured, and investments will be concentrated in high-ROIC growth areas. The business portfolio will be reorganized around the "2 Core + New Engine" strategy, focusing on steel and battery materials as the two core businesses while pursuing promising new growth engines. ROIC will be applied not only in business restructuring but also as a key metric for managing the profitability and capital efficiency of each business unit across the Group.

------

We will pursue a balanced approach to shareholder returns by enhancing shareholder value through corporate growth, while also returning profits to shareholders through treasury share cancellations and base dividends. In line with the share cancellation plan announced in July 2024, we will cancel a total of 6% of treasury shares over three years (2024–2026). For cash dividends, we will maintain a base dividend of KRW 10,000 per share annually, funded by 50–60% of standalone free cash flow, with residual funds used for additional shareholder returns. Under this policy, at least KRW 2.3 trillion will be returned to shareholders over the three-year period.

As part of these measures, 2% of existing treasury shares were cancelled between 2024 and 2025, totaling 4% to date. In addition, in July 2024, we repurchased and immediately cancelled treasury shares worth KRW 100 billion.

The plan also includes commitments to strengthen our advanced governance system led by independent outside directors. Enhancements will be made to the appointment process for the Chair and outside directors, and we will take the lead in managing group-wide ESG risks by reinforcing its ESG governance framework.

To ensure Board-level engagement and credibility of the plan, we presented the "POSCO HOLDINGS Corporate Value-Up Plan" at the 10th Board Meeting of 2024, held in December.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Describe any important governance policies that the company has established, excluding the Core (Sub-) Principles mentioned above.

POSCO HOLDINGS strictly prohibits child labor and forced labor at all domestic and international business sites. The Company respects international human rights standards, including the Universal Declaration of Human Rights and the UN Guiding Principles on Business and Human Rights (UNGPs). We also support globally recognized sustainability frameworks such as the UN Sustainable Development Goals (SDGs), the UN Global Compact, the OECD Guidelines for Multinational Enterprises, and ISO 26000. In February 2025, POSCO Group reaffirmed its commitment to global human rights standards by issuing the Group Human Rights Management Declaration, jointly signed by the CEO and the heads of major operating companies.

Since transitioning to a holding company structure, POSCO HOLDINGS has strengthened its group-level ESG governance by launching the Group ESG Council and the ESG Session. The Group ESG Council—chaired by the CEO and convened semiannually—is a top-level management body composed of the CEOs of major operating companies, the Head of Safety and Environment at POSCO, and key executives of POSCO HOLDINGS. The Council oversees core ESG issues and performance across the POSCO Group and reports key findings to the ESG Committee and the Board of Directors. Additionally, the ESG Session, which all Board members attend annually, serves as a platform to discuss group-level ESG issues. The ESG Committee—comprising three outside directors and one inside director—meets on an ad hoc basis to deliberate group-wide ESG strategies and major policies. It also monitors ESG-related matters across key domestic and international operations, providing guidance and oversight to support executive decision-making.

------

As part of our double materiality assessment process, POSCO HOLDINGS has organized stakeholder roundtables since 2022 to identify key ESG issues. In April 2025, POSCO HOLDINGS executives gathered direct feedback from a broad range of stakeholders, including investors, customers, business partners, and external ESG experts. The finalized list of material ESG issues, along with relevant policies and strategies, will be disclosed in the 2025 POSCO HOLDINGS Sustainability Report, scheduled for publication in June 2025. Since 2004, POSCO HOLDINGS has published its Sustainability Report annually on its official website. Each report undergoes third-party assurance by an independent accounting firm to ensure objectivity and credibility.
