Cerus Corporation Registers Up to $150.0 Million in Mixed Securities via Shelf Process

Cerus Corporation, a Delaware-incorporated company headquartered at 1220 Concord Ave., Suite 600, Concord, California, filed a preliminary Form S-3 registration statement with the SEC on November 2, 2026. According to the filing, the company is utilizing a "shelf" registration process, under which it may offer and sell up to an aggregate of $150.0 million of any combination of common stock, preferred stock, debt securities, and warrants to purchase any such securities, either individually or in combination.

The filing states that each time Cerus offers securities under this shelf registration, it will provide a prospectus supplement containing specific terms of that offering. The company may also authorize one or more free writing prospectuses. According to the prospectus, common stock may also be issued upon conversion of debt securities or preferred stock, and common stock, preferred stock, or debt securities may be issued upon the exercise of warrants. The prospectus notes that "this prospectus may not be used to consummate a sale of securities unless accompanied by a prospectus supplement."

The filing identifies Vivek K. Jayaraman as President and Chief Executive Officer and Chrystal Jensen as Chief Legal Officer and General Counsel. The registration statement has not yet been declared effective by the SEC, and the filing notes it may be amended before effectiveness. The prospectus describes investing in Cerus securities as involving "a high degree of risk" and directs investors to review risk factors in applicable prospectus supplements and incorporated documents. Net proceeds and pricing details for any specific offering will be set forth in the relevant prospectus supplement, according to the filing.
