Jasper Therapeutics, Inc. (NASDAQ:JSPR) ("Jasper" or the "Company"), today announced that Jasper has completed the acquisition of Kira Pharmaceuticals ("Kira"), a former Cayman limited company that was engaged in the design of complement therapies to treat immune-mediated diseases, in an all-stock transaction (together, the "Combined Company"). Concurrent with the acquisition, Jasper entered into a securities purchase agreement for the sale of non-voting convertible preferred stock (the "Preferred Stock") in a private placement transaction co-led by Affinity Asset Advisors, LLC and Ikarian Capital LLC with participation from Columbia Threadneedle Investments, Sirenia Capital Management LP, Brahma Capital, Balyasny Asset Management, SilverArc Capital, Squadron Capital Management, Nazare Partners LP, and Mirador Therapeutics as well as other leading life sciences investors and certain members of Kira management. The private placement is expected to result in total gross proceeds of approximately $132 million. The proceeds from the private placement will be used to fund development of the Combined Company’s pipeline through the second half of 2028. The Combined Company will focus on advancing a consolidated pipeline of potential best-in-class innovative therapies for immunologically-driven disorders, including KP-104, a potential best-in-class dual-complement inhibitor for the treatment of paroxysmal nocturnal hemoglobinuria (PNH) and high unmet need nephrology disorders, briquilimab, an anti-KIT antibody with broad therapeutic utility across multiple transplant and immunologic indications, and KP-701, a novel, dual-acting anti-CD79BxCD32B monoclonal antibody (mAb) for autoantibody-mediated disorders. The Combined Company will continue to trade on Nasdaq under the ticker symbol "JSPR."
