NOTICE TO U.S. INVESTORS IN MURAL

The Transaction relates to the securities of an Irish company and is subject to Irish procedural and disclosure requirements that are different from those of the United States. Any financial statements or other financial information included in this website may have been prepared in accordance with non-U.S. accounting standards that may not be comparable to the financial statements of U.S. companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the United States. It may be difficult for U.S. holders of shares to enforce their rights and any claims they may have arising under the U.S. federal securities laws in connection with the Transaction, since Mural is located in a country other than the United States, and some or all of their officers and directors may be residents of countries other than the United States. U.S. holders of shares may not be able to sue Mural or its officers or directors in a non-U.S. court for violations of the U.S. securities laws. Further, it may be difficult to compel Mural and its respective affiliates to subject themselves to the jurisdiction or judgment of a U.S. court.

FORWARD LOOKING STATEMENTS

The Information contained or referred to in the website may contain forward-looking statements with respect to certain aspects of the business of Mural, XOMA Royalty, any Interested Party, strategies and plans and their expectations relating to the Transaction. Because such statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied by such forward-looking statements. Any forward-looking statements contained in the Information are based on XOMA Royalty’s and/or Mural’s, as applicable, current expectations of future events and are subject to a number of risks and uncertainties that could cause actual results to differ materially and adversely from those set forth in or implied by such forward-looking statements. Risks that contribute to the uncertain nature of the forward-looking statements include, among others, all and those other risks and uncertainties set forth in the company’s filings with the Securities and Exchange Commission (“SEC”), including its Annual Report on Form 10-K for the fiscal year ended December 31, 2024 and in subsequent filings the Company may make with the SEC. All forward-looking statements contained in the Information speak only as of the date of the relevant document. XOMA Royalty anticipates that subsequent events and developments will cause its views to change. However, XOMA Royalty undertakes no obligation to update such forward-looking statements to reflect events that occur or circumstances that exist after the date of the relevant document, except as required by law.
