The Company is in the process of finalizing its financial results for the year ended December 31, 2025, and the foregoing preliminary financial data is based on available information to date. This financial data for the year ended December 31, 2025 is preliminary and may change. This preliminary financial data has been prepared by, and is the responsibility of, the Company’s management. Ernst & Young LLP, the Company’s independent registered public accounting firm, has not audited, reviewed, compiled or performed any procedures with respect to this preliminary financial data, nor have any other independent accountants. Accordingly, Ernst & Young LLP does not express an opinion or any other form of assurance with respect thereto. The Company’s actual results for this period may differ from the foregoing preliminary financial data and such changes could be material. In addition, this preliminary financial data should not be viewed as a substitute for full financial statements for the year ended December 31, 2025 prepared in accordance with U.S. generally accepted accounting standards. Additional information that will be material to investors will be provided in these financial statements, and, accordingly, investors should not place undue reliance on the limited preliminary information being provided herein. This Current Report on Form 8-K includes forward-looking statements including statements regarding the Company’s current expectations, financial results and anticipated results of operations, including expected combined annual research and development and selling, general and administrative expenses for 2025, 2026 and 2027. Generally, forward-looking statements can be identified through the use of words or phrases such as “could,” “will,” “would,” “can,” “estimate,” “continue,” “ongoing,” “consider,” “anticipate,” “intend,” “seek,” “plan,” “project,” “expect,” “should,” “prepare”, or “aim”, the negative of these terms, or other comparable terminology, although not all forward-looking statements contain these words. Forward-looking statements involve estimates, assumptions, risks, and uncertainties that could cause actual results or outcomes to differ materially from those expressed or implied in any forward-looking statements, and, therefore, you should not place considerable reliance on any such forward-looking statements. Such risks and uncertainties include, among others, that the Company’s full financial statements for the year ended December 31, 2025 prepared in accordance with U.S. generally accepted accounting standards may differ materially from the preliminary and unaudited amounts reported herein and other risks and uncertainties are identified in the presentation and under the heading “Risk Factors” in the Company’s most recent Annual Report on Form 10-K, in subsequent Quarterly Reports on Form 10-Q and in any subsequent filings with the Securities and Exchange Commission. Further, any forward-looking statement speaks only as of the date when it is made, and the Company undertakes no obligation to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise, unless required by law. New factors emerge from time to time, and it is not possible for the Company to predict which factors will arise. In addition, the Company cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.
