Basic disclosure policy

As a company trusted widely by society, Shionogi & Co., Ltd. (hereafter “the Company”) recognizes that management transparency is one of its most important responsibilities. Based on this recognition, the Company discloses information, including that related to its group companies, to all stakeholders in a fair, timely, appropriate and continuous manner.

Disclosure standards

The Company discloses information in conformity with the Companies Act, the Financial Instruments and Exchange Act, and all other applicable laws and regulations, as well as the timely disclosure rules stipulated by the stock exchanges on which the Company is listed.


The Company actively discloses information that it believes is necessary for shareholders and investors to make their investment decisions, even when the information lies outside the scope of the applicable laws and regulations and timely disclosure rules. The Company also actively discloses information about its efforts to meet the interests and demands of society.

Disclosure methods

Pursuant to the applicable laws and regulations and timely disclosure rules, the Company discloses information through the Electronic Disclosure for Investors’ NETwork (EDINET), a system provided by the Financial Services Agency to make securities reports and other disclosure documents covered by the Financial Instruments and Exchange Act and other relevant legislation publicly available, or through the Timely Disclosure network (TDnet) provided by the stock exchanges, amongst other methods.


Information disclosed via EDINET or TDnet is posted as soon as possible on the Company’s website to ensure the timeliness and fairness of information disclosure.


Based on the principle of timely disclosure, information other than that disclosed via EDINET or TDnet is also disclosed through press releases, explanatory meetings, the Company’s website, and/or other means, in a fair and prompt manner.


The Company endeavors to make information available in English as well as in Japanese to facilitate understanding by as many stakeholders as possible.

Prevention of insider trading

The Company prevents insider trading by stipulating in its internal rules clear guidelines for the proper control of internal information and the trading of shares or other securities; by ensuring that its officers and employees thoroughly understand the regulations concerning insider trading; and by properly operating its established system for managing trading activities. 

Quiet period

To prevent the leakage of financial results and ensure legal compliance and fairness, the Company observes a quiet period from the day after the closing date of each quarter until the date of the financial results announcement for such quarter.


During this period, the Company does not make any comments or answer any inquiries regarding financial results. However, if the Company anticipates a significant difference between the original forecasts and the actual results during the quiet period, the Company will disclose such information in a timely and appropriate manner based on the disclosure rules.

Forward-looking statements

Information disclosed by the Company may contain forward-looking statements, such as financial forecasts, strategies and business plans. These forward-looking statements reflect the management’s judgment based on the information available at the time of disclosure, and the actual results may differ materially due to various factors, including changes in economic trends and market environments.
