Disclosure policy

1. Basic policy on information disclosure

Hamamatsu Photonics seeks to build mutual trust with its shareholders, investors and other stakeholders by ensuring timely, appropriate and fair disclosure of information. The Company also endeavors to promote a better understanding of its business through constructive dialogue and ongoing communication with its stakeholders.

2. Disclosure standards

The Company appropriately discloses information that may have a material impact on investment decisions in accordance with the Financial Instruments and Exchange Act, other applicable laws and regulations, the Fair Disclosure Rules, and the Timely Disclosure Rules stipulated by the Tokyo Stock Exchange. In addition to information required to be disclosed under applicable laws, regulations and stock exchange rules, the Company endeavors to voluntarily provide, through its corporate website and other appropriate means, information that it considers useful in promoting a better understanding of the Company among its shareholders and investors.

3. Methods of information disclosure

Disclosure documents required under the Financial Instruments and Exchange Act and other applicable laws and regulations are filed and disclosed through the Electronic Disclosure for Investors’ NETwork (EDINET), which is operated by the Financial Services Agency of Japan.

Information subject to the timely disclosure requirements of the Tokyo Stock Exchange is disclosed through the Timely Disclosure network (TDnet). These disclosure documents and information are also posted promptly on the Company’s corporate website following disclosure.

4. Forward-looking statements

Forward-looking statements disclosed by the Company are based on information available at the time of disclosure and on judgments made by the Company at that time, and involve risks and uncertainties.

Actual operating results and other outcomes may differ from those expressed or implied in such forward-looking statements due to various factors, including changes in economic conditions, market trends and foreign exchange rates.

5. Quiet period

In order to prevent the leakage of financial information and ensure fair disclosure, the Company, in principle, observes a quiet period from the day following the end of each quarterly reporting period until the date on which the relevant financial results are announced. During this period, the Company refrains from commenting on or responding to questions concerning its financial results. However, if the Company determines during the quiet period that its financial results are likely to differ significantly from its previously announced forecast, it will disclose the relevant information in a timely and appropriate manner.
