Corporate Governance

Policy and Basic Approach

The Nippon Kayaku Group recognizes that delivering its corporate vision under the KAYAKU spirit requires focus on two important issues: timely and impartial information disclosure to all shareholders and investors, and guaranteed transparent management based on strengthened checking functions. Having judged that management functions can be most effectively demonstrated through decision-making via a Board of Director council system, and corporate governance via an Audit & Supervisory Board system, we will continue to tackle the expansion and reinforcement of corporate governance as a key managerial issue.

Business Execution System

Nippon Kayaku is a company which has adopted an Audit & Supervisory Board System. Furthermore, in order to rapidly respond to changes in the business environment and achieve flexible business execution, we have introduced an Executive Director System to clarify the separate managerial roles of “decision-making and supervisory functions” and “business execution functions.” By strengthening each of these functions are we carrying our appropriate decision-making and rapid execution of business.

Audit & Supervisory Board

Our Audit & Supervisory Board consists of five members, three of whom are outside and two of whom are full-time inside, with one of the latter serving as chair. In line with the audit policies, methods, plans, and division of roles determined by this board at the start of every new period does each member join key meetings, including those of the Board of Directors, review important documents, and, through assessing business execution conditions, audit and supervise the performance of Director duties from an independent standpoint. The two full-time members join management meetings and other such meetings of importance, and audit the overall management situation, Board Member performance and Executive Director performance, through conducting site visits, hearings, and reviews of meeting minutes and other key documents for all main divisions, workplaces and group subsidiaries. The non-full-time members sit in on Audit & Supervisory Board meetings to receive the aforementioned audit status reports, accompany full-time members on site visits, and participate, as appropriate, in information-exchange sessions with the Audit Team of the Inside Audit Division and the Inside Control Management Division (in charge of compliance and risk management). In such meetings will these members offer advice and voice necessary opinions.

Our improvement cycle involves conducting an annual Board of Directors Effectiveness Evaluation to grasp the current state of affairs, extract key issues, and devise a relevant Action Plan.

Board of Directors Effectiveness Evaluation
Board of Directors Effectiveness Evaluation
Status of Initiatives on Issues extracted from the FY2024 Effectiveness Evaluation
Issues arising from the FY2024 Effectiveness Evaluation Initiatives implemented in FY2025
1 Further enhancement of discussions and oversight regarding human capital management initiatives, including the development of a diverse pipeline of core personnel. The Nominations & Remuneration Advisory Committee discussed initiatives related to human capital management and related disclosure content, and reported on its discussions to the Board of Directors. In addition, the details of these initiatives were disclosed in the Annual Securities Report, on our company website, in the Corporate Governance Report, and in Integrated Report 2025, respectively. Furthermore, at a special meeting of the Board of Directors held in November 2025, the Board discussed the basic policy on human capital and other matters aimed at realizing our desired state in 2035.
2 Strengthening oversight of cybersecurity measures. The current status of cybersecurity measures and incidents that occurred were reported to the Board of Directors every six months, and the Board discussed the content of those reports.
3 Ongoing discussions and enhanced oversight on management strategies, the company’s future vision, and initiatives focused on improving the price-to-book ratio (PBR). The Board of Directors discussed the formulation of the next management plan as appropriate, and the current analysis, basic policy and other matters based on those discussions were compiled into the “New Long-term Management Plan Formulation Policy” which was approved by resolution of the Board of Directors and disclosed at the financial results briefing for the second quarter of the fiscal year ending March 31, 2026. In addition, measures focused on improving the price-to-book ratio (PBR), which had continued to be identified as an issue from the previous fiscal year, were discussed as one of the points at issue in formulating the next management plan.
Evaluation Results, Future Issues and Action Plan

The Board’s analysis and evaluation of survey results revealed relative improvements in survey scores stemming from the various improvements achieved through our action plans.
Overall, the analysis confirmed that our Board of Directors is effectively fulfilling its roles and responsibilities. However, from the perspective of further enhancing the effectiveness of the Board of Directors, the following issues have been identified:

Future issues Action Plan
1 Enhancement of discussions regarding the succession plan The Board of Directors and the Nomination and Compensation Advisory Committee will discuss the disclosure of the succession plan for the President, as well as whether succession plans for Directors other than the President are necessary and, if so, their details.
2 Enhancement of discussions regarding the use of generative AI and its risks The Directors in charge of operations related to generative AI will report to the Board of Directors on the status of the use of generative AI and the risks anticipated, and the Board of Directors will discuss the content of such report.
3 Review of the criteria for matters to be submitted in order to secure time for discussions on important matters After organizing the basic approach to the criteria for matters to be submitted for resolution by the Board of Directors, the Company will optimize the number of agenda items through a review of the Board of Directors Regulations and develop an environment in which sufficient deliberation time can be secured for matters of high importance.

The following issues were identified, and at the Board of Directors meeting in March 2026, an action plan to be addressed by the Board of Directors in FY 2026 was formulated and has been steadily implemented since April of the same year. We will make continued efforts to improve Board effectiveness going forward.

Director Remuneration

The 149th Ordinary General Meeting of Shareholders on August 30th 2006 saw Nippon Kayaku determine annual upper limits of director (board member) remuneration at 360 million yen for fixed remuneration and 200 million yen for bonuses. As of the end of that AGM, the Board was comprised of eight members, with zero Outside Directors. The 164th Ordinary AGM of June 25th 2021, meanwhile, saw a 100-million- yen annual limit voted through on Restricted Stock Transfer Monetary Remuneration, applying to the relevant directors and running separately to existing director remuneration arrangements. As of the end of that AGM, the Board was comprised of 9 members, of which three were Outside Directors.
The 149th Ordinary AGM also set annual limits on Audit & Supervisory Board Member remuneration at 90 million yen. There were five Audit & Supervisory Board Members as of the end of that meeting.
To ensure the appropriateness of matters discussed and transparency in the decision-making process, the Nominations & Remuneration Advisory Committee - the majority of whose members is comprised of independent Outside Directors - deliberates matters relating to Director remuneration in response to inquiries from the Board of Directors, and reports back to the Board. Such a process enabled the Board Meeting of June 25, 2021 to finalize Nippon Kayaku’s policy regarding the individual Director remuneration.
With a view to achieving our KAYAKU spirit corporate vision, in addition to sufficiently functioning as an incentive to sustainably improve corporate value and share that value with shareholders, Director remuneration shall also be structured at a competitive level to help us secure excellent personnel.
Specifically, Director remuneration pertaining to the execution of business activities shall consist of basic remuneration and incentive remuneration (performance-linked bonuses and stock remuneration). The remuneration of Outside Directors, with their standpoints independent from business execution, shall be limited to basic remuneration in view of their responsibility.
The amount of basic remuneration for Directors involved in executing business activities shall be determined based on whether or not they hold representative authority, their assigned duties, and other factors, and shall be paid as monthly monetary remuneration.

Executive Remuneration Mix
Executive Remuneration Mix

Remuneration Structure

The ratio of remuneration by type for Directors involved in executing business shall be roughly 60% for basic remuneration and 40% for incentive remuneration, and shall be determined based on the Director’s position, responsibilities and other factors.
Regarding decisions on the content of individual remuneration for Directors, the Nominations & Remuneration Advisory Committee will consider a draft from various perspectives, such as consistency with overall policy direction, and report back to the Board.
he Board then deliberates the Committee’s report and decides the content of individual Director remuneration. Audit & Supervisory Board Member remuneration shall be limited to fixed remuneration in view of their responsibility to monitor the execution Director duties, with the amount to be determined through discussions with those Members within the yearly remuneration limit range.

Performance-related Remuneration

The performance-linked bonuses of individual Directors involved in executing business activities shall be calculated based on the achievement rate and rate of change against the targets for consolidated net sales and consolidated operating profit set forth in the annual business plan and the target value for return on equity (ROE) set forth in the Mid-term Management Plan, while also taking into account the business results of the departments for which they are responsible and the degree of achievement of mid- to long-term key-issue targets, and shall be paid in cash at a fixed time following the end of each fiscal year. The reasons for selecting these performance targets are that they are considered to be the most appropriate indicators for heightening awareness of short-term business performance improvement mainly with respect to consolidated net sales and consolidated operating profit, while also heightening awareness of the achievement of the Mid-term Management Plan and the practice of our sustainable management by using the achievement rate and rate of change of return on equity (ROE) as targets. Directors involved in executing business activities shall be awarded transfer-restricted stock, with a fixed transfer-restriction period attached, at a certain time every year. The aim is to motivate Directors to contribute to improving mid-to long-term corporate and shareholder value under the wider aim of sharing value with shareholders. Monetary remuneration credits equivalent to the stock remuneration and the number of shares to be awarded shall be determined based on the Director’s position and responsibilities, as well as our stock price and other factors.

Conflicts of Interest

Nippon Kayaku has specified in the Rules of the Board of Directors that any Director engaging in competitive or personal transactions must receive prior Board approval and report the results of such transactions to the Board. In addition to the aforementioned, we also verify at the end of the fiscal year whether either Directors and Audit & Supervisory Board Members themselves or their close relatives (to within two degrees) have engaged in transactions with the Nippon Kayaku Group. The Rules of the Board of Directors specify that Board approval is required for important transactions with principal shareholders and affiliated companies.

Cross-shareholdings Policy

Policy on Cross-shareholdings

Nippon Kayaku’s shareholding purposes can be divided into two categories: stock investments for net investment purposes, and stocks held for purposes other than net investment. The former refers to investments made in order to derive gains from changes in share value or dividends, while the latter refers to stocks held for other purposes.
We have pressed ahead with further reassessments of our cross-shareholding purposes and investment efficiency, and are working towards a target of reducing our cross-shareholdings to 6% or less of consolidated net assets by March 2029.

Examination of Shareholding Suitability

Nippon Kayaku invests in cross-shareholdings from the standpoints of improving medium-to-long-term corporate value, and maintaining and strengthening relationships with our customers.
Each year sees individual cross-shareholdings examined by the Board of Directors from medium-to-long-term corporate value perspectives. Cross-shareholdings deemed no longer necessary are, with due consideration given to market impact, consequently sold off.

Shift in Cross-Shareholdings Policy

As mentioned above, Nippon Kayaku invests in cross-shareholdings from the standpoints of improving medium-to-long-term corporate value, and maintaining and strengthening relationships with our customers. Each year sees individual cross-shareholdings examined by the Board of Directors from medium-to-long-term corporate value perspectives.
Cross-shareholdings deemed no longer necessary are, with due consideration given to market impact, consequently sold off.
Our cross-shareholding balance for FY2025 reached 7.9% of consolidated net assets, marking a 2.0% drop on FY2024 due to, among other things, our pressing ahead with sales of cross-shareholdings. We will work on accelerating such sales to as to guarantee meeting our next target.
