‌Reference Documents for the General Meeting of Shareholders Proposals and Reference Matters ‌Proposal No. 1: Appropriation of Surplus

The AGC Group will, while maintaining financial soundness, prioritize the use of cash generated from business activities for capital investment in strategic businesses and other areas necessary for future growth, M&A, and R&D, etc.

On shareholder return, the Company will maintain stable dividends with a target ratio of dividends attributable to owners of parent company (DOE) of around 3% while comprehensively considering such factors as consolidated business performance in the fiscal year under review and future demand for funds. In addition, the Company will make comprehensive decisions concerning the acquisition of treasury shares, while taking into consideration comparisons with other investment projects, capital efficiency, and financial position.

On the appropriation of surplus for this term, the proposal is made under this policy as follows:

Matters concerning year-end dividends

Taking into account the business performance for this term, managerial environment, future business development, etc., the proposal is 105 yen per share.

  1. Matters concerning the allocation of dividend property for shareholders and their total amount

    105 yen per ordinary share of the Company Total amount: 22,298,238,795 yen

  2. Effective date of payment of dividends March 30, 2026

If this proposal is approved and adopted as proposed, the annual dividends per share for this term, including the interim dividends, will be 210 yen per share, which is the same amount as the previous term.

‌Proposal No. 2: Partial Amendment to the Articles of Incorporation
  1. Reasons for the Amendments

    1. To realize value creation based on the AGC Group's competitive advantages and further strengthen the supervisory function of the Board of Directors, the Company intends to transition to a "Company with an Audit & Supervisory Committee" and to establish a Board of Directors where Outside Directors constitute the majority. In this transition, we will redefine the roles of the Board as: "setting the overall direction of management from a longterm perspective," "encouraging appropriate risk-taking by the management," and "overseeing the realization of value creation and evaluating and appointing executive officers." On such basis, we will build a structure that maximizes these roles and deepen discussions to accelerate the AGC Group's value creation.

    2. In conjunction with the transition to a Company with an Audit & Supervisory Committee, the Company will make necessary amendments such as newly establishing provisions concerning Audit & Supervisory Committee Members and the Audit & Supervisory Committee, deleting provisions concerning Audit & Supervisory Board Members and the Audit & Supervisory Board, and establishing provisions related to the delegation of decision on important business executions.

    3. In line with the addition and deletion of articles, necessary amendments such as renumbering of articles and adding paragraph numbers will be made.

‌Proposal No. 5: Determination of the Amount of Remuneration, etc. for Directors (excluding Directors who are Audit & Supervisory Committee Members)

At the 97th Ordinary General Meeting of Shareholders held on March 30, 2022, it was resolved to set the amount of compensation, etc. for the Directors regarding monthly compensation and bonus at 750 million yen or less per year (including 67 million yen or less per year for Outside Directors).

If Proposal No. 2 is approved and adopted as proposed, the Company will transition to a company with an Audit & Supervisory Committee. Accordingly, we propose to abolish the current provisions on Directors' compensation, and to set the amount of compensation relating to monthly compensation and bonus for Directors (excluding Directors who are Audit & Supervisory Committee Members) at 750 million yen or less per year, as with the current upper limit of the amount of compensation, etc. for the Directors, and taking into account the responsibilities of Outside Directors and recent economic conditions and other circumstances, set the portion for Outside Directors at 88 million yen or less per year.

If this proposal is approved and adopted as proposed, the Company's "Policy for Determining Compensation, etc. for Officers" (described in the matters provided by electronic measures under Business Report "3. Matters Concerning Company Officers (2) Directors and Audit & Supervisory Board Members") will, based on a resolution of the Board of Directors, be revised to reflect the transition to a company with an Audit & Supervisory Committee while remaining, in substance, the same in content.

This proposal is in line with the revised Policy for Determining Compensation, etc. for Officers, and the Board of Directors resolved to approve it after receiving a report to that effect from the Compensation Committee, the majority of the members of which are Outside Directors and which is chaired by an Outside Director; accordingly, we consider the proposal to be reasonable.

If Proposals No. 2 and No. 3 are approved and adopted as proposed, the Directors who will be subject to this proposal (excluding Directors who are Audit & Supervisory Committee Members) will be six in number (of whom three will be Outside Directors).

The effectiveness of the resolution on this Proposal shall be conditional upon the amendments to the Articles of Incorporation proposed in Proposal No. 2 becomes effective.

‌Proposal No. 6: Determination of the Amount of Remuneration, etc. for Directors who are Audit & Supervisory Committee Members

If Proposal No. 2 is approved and adopted as proposed, the Company will transition to a company with an Audit & Supervisory Committee. Accordingly, taking into account the responsibilities of Directors who will serve as Audit & Supervisory Committee Members and recent economic conditions and other circumstances, we propose to set the maximum amount of remuneration, etc. relating to the monthly remuneration for Directors who are Audit & Supervisory Committee Members at 150 million yen per year. For reference, the current maximum annual amount for monthly remuneration of Audit & Supervisory Board Members is 120 million yen.

In order to ensure the appropriateness of directors' remuneration and the transparency of the decision-making process, the Board of Directors resolved to approve it after receiving a report to that effect from the Compensation Committee, the majority of the members of which are Outside Directors and which is chaired by an Outside Director; accordingly, we consider the proposal to be reasonable.

If Proposals No. 2 and 4 are approved as proposed, the number of Directors who are Audit & Supervisory Committee Members subject to this proposal will be four.

The effectiveness of the resolution on this Proposal shall be conditional upon the amendments to the Articles of Incorporation proposed in Proposal No. 2 becomes effective.
