In order to receive legitimate recognition from the market, a timely, consistent and credible disclosure of information will be made to all capital market participants, such as investors and shareholders, in accordance with the Financial Instruments and Exchange Act of Japan and relevant rules of the stock exchange on which shares of Chugai are listed. In addition, measures to allow easy access to disclosed information will be established to ensure transparency.

1. Material Information required to be disclosed under the Financial Instruments and Exchange Act of Japan and Timely Disclosure Rules established by Tokyo Stock Exchange will be disclosed through the Timely Disclosure network (TDnet).
2. Information other than (1) above that may affect investment decisions will be disclosed in a timely manner through press releases, press conferences, briefings, etc., depending on the importance and urgency of the information to be disclosed.
3. Information disclosed under (1) and (2) will be promptly posted on Chugai's website following disclosure.
4. For the convenience of capital market participants, Chugai will make efforts to provide English translations of the information disclosed in Japanese (excluding personnel information), provided that the Japanese original prevails over its English translation in the case of any discrepancy found between documentation.

Forward-looking statements disclosed by Chugai (including information posted on the website) , such as its business plans, forecasts or strategy, may include risks and uncertainties. Actual results may materially differ from the forward-looking statements.

Chugai will not make any comments on evaluations, business forecasts and market rumors about Chugai made by third parties. However, should this information substantially affect the capital markets, be considered by Chugai to be potentially damaging to its business, or should Chugai be requested by the stock exchange on which shares of Chugai are listed or other institutions to provide an explanation or take action, Chugai may make some comment.

Chugai will make the period from the next business day of the end of each quarter to the day of the announcement of the financial results of the quarter a "quiet period," during which Chugai will refrain from making any comments on undisclosed financial results (i.e. financial information and business activities including research and development) requested by capital market participants.

Chugai has established a Corporate Communications Committee. The Committee is a corporate management committee composed of the CFO, Head of Finance Supervisory Division, and heads of the Corporate Communications Department, the Corporate Planning Department, the Finance & Accounting Department, the Risk & Compliance Department, the Human Resources Management Department and ESG Department. The committee holds regular meetings and is responsible for the establishment, revision and internal dissemination of the Disclosure Policy, and for the management and promotion of information collection, disclosure and other related activities. Top management, including the CEO and key executive officers, has primary accountability for disclosure. In addition, the Corporate Communications Department takes the lead in coordinating with relevant departments, using various tools to communicate promptly and effectively.
