On January 11, 2026, Cerus Corporation (the “Company”) announced its preliminary product revenue results for the fourth quarter and fiscal year ended December 31, 2025. A copy of the Company’s press release, entitled “Cerus Corporation Announces Preliminary Fourth Quarter and Full-Year 2025 Product Revenue and Provides Outlook,” is furnished pursuant to Item 2.02 as Exhibit 99.1 hereto.

Such product revenue results as reported are preliminary, unaudited and subject to completion. The Company’s independent registered public accounting firm has not audited or performed any procedures with respect to these preliminary results and does not express an opinion or any other form of assurance with respect thereto. The Company’s financial closing procedures for the three months and year ended December 31, 2025 are not yet complete and, as a result, the final results upon completion of the closing procedures may vary from the preliminary estimates, and any such differences may be material. The Company’s product revenue information presented herein should not be viewed as a substitute for the information set forth in the full financial statements prepared in accordance with U.S. generally accepted accounting principles, and undue reliance should not be placed on these preliminary product revenue results.

The information in this report, including the exhibit hereto, shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of Section 11 and 12(a)(2) of the Securities Act of 1933, as amended. The information contained herein and in the accompanying exhibit shall not be incorporated by reference into any filing with the U.S. Securities and Exchange Commission made by the Company, whether made before or after the date hereof, except as shall be expressly set forth by specific reference in such filing.
