DiaMedica Therapeutics Raises $30 Million in Private Placement to Accelerate Industry Leading Preeclampsia and Fetal Growth Restriction Pipeline

DiaMedica Therapeutics Inc. (NASDAQ:DMAC), a clinical-stage biopharmaceutical company focused on developing novel treatments for preeclampsia, fetal growth restriction and acute ischemic stroke, today announced definitive agreements for a $30.1 million private placement of common shares led by current investors. No placement agent was engaged for this transaction.

Pursuant to the terms of the securities purchase agreements, the Company will issue a total of 8,606,426 common shares at a purchase price of $3.50 per share. The private placement is expected to close on or about July 23, 2025, subject to the satisfaction of customary closing conditions.

The capital raised is expected to fund the Company's operations for more than two years and support upcoming milestones including the submission of an investigational new drug (IND) application in the United States for preeclampsia and fetal growth restriction and a Phase 2b study to further evaluate DM199 in both indications, pending IND approval.

"This financing allows us to rapidly accelerate our development efforts in preeclampsia and fetal growth restriction, both of which have no approved treatment options currently," said Rick Pauls, President and CEO of DiaMedica. "We believe DM199 has the potential to be a disease-modifying therapy for these patients, and look forward to building upon what is already the most advanced clinical program targeting these conditions."

The offer and sale of the common shares in the private placement have not been registered under the U.S. Securities Act of 1933, as amended (the "Securities Act"), or any state or other applicable jurisdiction's securities laws, and such common shares may not be offered or sold in the United States except pursuant to an effective registration statement or an applicable exemption from the registration requirements of the Securities Act and applicable state and other securities laws. The Company has agreed to file a registration statement with the U.S. Securities and Exchange Commission registering the resale of the common shares issued in the private placement.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy the foregoing securities, nor shall there be any sale of these securities in any state or other jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or other jurisdiction.

Required Canadian Related Party Transaction Disclosure

DiaMedica has received binding commitments for participation in the private placement from certain non-management, related parties, in the aggregate amount of $30.1 million or 8,606,426 common shares. Accordingly, the private placement constitutes a "related party transaction" as such term is defined in Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions ("MI 61-101") of the Canadian Securities Administrators. The private placement will be exempt from the valuation and the minority shareholder approval requirements of MI 61-101 under the exemptions contained in section 5.5(a) and 5.7(1)(a), respectively, as neither the fair market value of the common shares nor the fair market value of the consideration paid for the common shares insofar as it involves the related parties is more than 25% of the Company's market capitalization.

About DM199 (rinvecalinase alfa)

DM199 (rinvecalinase alfa) is a recombinant form of human tissue kallikrein-1 (rhKLK1) in clinical development for preeclampsia, fetal growth restriction and acute ischemic stroke. KLK1 is a serine protease enzyme that plays an important role in the regulation of diverse physiological processes via a molecular mechanism that increases production of nitric oxide, prostacyclin and endothelium-derived hyperpolarizing factor. In preeclampsia and fetal growth restriction, DM199 is intended to lower blood pressure, enhance endothelial health and improve perfusion to maternal organs and the placenta while for stroke intended to increase collateral circulation in the penumbra following a stroke.
