IR Basic Policy

1. Basic Philosophy

Under our Corporate Philosophy of “Creation, Reliability, Growth,” NSSOL will continue to build relationships of trust with our customers and grow alongside them by creating true value, thereby contributing to the development of society. We have also established in our Global Code of Business Conduct that we will broadly communicate with society, actively and fairly disclose corporate information, and thoroughly protect and manage all types of information.

Based on Corporate Philosophy and the Global Code of Business Conduct, we recognize that timely, appropriate, and fair information disclosure and constructive dialogue with shareholders and investors are important to building relationships of trust and achieving sustainable growth and medium- to long-term enhancement of corporate value.

We are committed to promoting constructive dialogue with our shareholders and investors based on the principles of the Fair Disclosure Rule, the Corporate Governance Code, and the Stewardship Code.

2. Information Disclosure Standards

We will comply with the Companies Act, the Financial Instruments and Exchange Act, other applicable laws and regulations, and the timely disclosure rules established by the financial instruments exchanges on which our securities are listed, and we will disclose information in accordance with these requirements. In addition to information subject to timely disclosure rules, we will proactively disclose, to the extent possible, information that is useful to investors in making investment decisions, and we will comply with the Fair Disclosure Rules.

3. Methods of Information Disclosure

Information required to be disclosed under the Companies Act (such as business reports) will be disclosed to our shareholders through appropriate means, including by mailing it to them and promptly posting it on our website. Information required to be disclosed under the Financial Instruments and Exchange Act or the timely disclosure rules established by financial instruments exchanges will be disclosed through the Financial Services Agency’s electronic disclosure system “EDINET” and the timely disclosure information transmission system “TDnet” provided by the Tokyo Stock Exchange and will also be made available to various media outlets. Furthermore, to ensure that this information is communicated fairly and widely to all investors, we will also post it on our website.

4. Treatment of Performance Forecasts and Forward-Looking Statements

Performance forecasts and forward-looking statements disclosed by us are based on information available and certain assumptions at the time of disclosure, and do not constitute commitments or guarantees regarding future plan figures or the realization of measures. Please be aware that performance forecasts and forward-looking statements may be changed without notice due to various risks and uncertain or unpredictable factors after disclosure, and that actual results regarding performance, figures, etc. may differ significantly from forecasts and projections.

5. Quiet Period

To ensure fairness in the disclosure of financial results information, we have established a “quiet period” for a certain period until each quarterly financial results announcement as described below, during which we refrain from commenting on or answering questions regarding financial results. However, if significant performance changes that fall under timely disclosure rules are anticipated, we will promptly disclose information in accordance with “Methods of Information Disclosure” above.

Quiet Period

• 1st Quarter: From June 13th until the announcement date
• 2nd Quarter: From September 12th until the announcement date
• 3rd Quarter: From December 12th until the announcement date
• 4th Quarter/Full Year: From March 13th until the announcement date

6. IR Structure

Under the supervision of the Director in charge of Corporate Affairs, the IR Department manages investor relations matters in coordination with related departments.

7. Methods of Dialogue

The IR Department plays a leading role in dialogue with shareholders. We also hold quarterly financial results briefings led by the Representative Director or the Director in charge of Corporate Affairs.

Furthermore, from the perspective of promoting constructive dialogue with shareholders and investors, directors including independent outside directors and executive officers will meet with shareholders, institutional investors, and analysts within a reasonable scope.

8. Methods for Internal Feedback

We will provide feedback on the insights gained through these dialogues to the Board of Directors and other relevant bodies as necessary and incorporate them into our various initiatives.

9. Measures for Managing Insider Information

We will manage insider information (unpublished facts) appropriately in accordance with our internal regulations, the “Regulations on the Management of Insider Information and Restrictions on Insider Trading.”
