DiaMedica operates in a highly regulated and competitive environment. The development, manufacturing and marketing of pharmaceutical products require approval from, and are subject to ongoing oversight by, the United States Food and Drug Administration (FDA) in the United States, the European Medicines Agency (EMA) in the European Union, and comparable agencies in other countries. We are in the clinical stage of development of our lead product candidate, DM199, for the treatment of PE, FGR and AIS. We have not completed the development of any product candidate and do not generate any revenues from the commercial sale of any product candidate. Our lead product candidate, DM199, requires significant additional clinical testing and investment prior to seeking marketing approval and is not expected to be commercially available for at least three to four years, if at all.

With respect to our PE clinical program, a Phase 2 open-label, single center, single-arm, safety and pharmacodynamic, proof-of-concept, investigator-sponsored study of DM199 for the treatment of PE is currently being conducted at the Tygerberg Hospital in Cape Town, South Africa. This Phase 2 study consists of three studies (Parts 1a, 1b and 2) in PE and a single study (Part 3) in FGR as follows:

Preeclampsia (PE)

Fetal Growth Restriction (FGR)

Up to 90 women with PE and potentially an additional 30 subjects with FGR may be evaluated. The first subject in Part 1a was enrolled in the fourth quarter of 2024 and interim results from Part 1a of the study were released in July 2025. The interim results (N=28 subjects) demonstrated that DM199 appears safe and well-tolerated with clinically-relevant pharmacodynamic activity with no evidence of placental transfer of DM199. Additionally, subjects in cohorts 6 through 9, the potentially therapeutic dose levels, exhibited rapid, statistically significant reductions in blood pressure with duration of effect that was sustained up to 24 hours post-infusion compared to pre-treatment baseline. The acceptance by the FDA of study data from clinical trials conducted outside the United States may be subject to certain conditions or may not be accepted at all. If the FDA does not accept such data, it would result in the need for additional participants or trials, which would be costly and time-consuming and delay regulatory approval and commercialization of our DM199 product candidate.

With respect to our AIS clinical program, we are currently conducting a Phase 2/3, adaptive design, randomized, double-blind, placebo-controlled trial of DM199 for the treatment of AIS, (the ReMEDy2 trial). Our ReMEDy2 trial is intended to enroll approximately 300 participants at up to 100 sites globally. The adaptive design component includes an interim analysis by our independent data safety monitoring board to be conducted after the first 200 participants have completed the trial. Based on the results of the interim analysis, the study may then be stopped for futility or the final sample size will be determined, ranging between 300 and 728 patients, according to a pre-determined statistical plan. We are currently conducting the trial in the United States, Canada, the United Kingdom and the European Union. We recently commenced site initiations and enrollments in six European countries. We have experienced and continue to experience slower than expected site activations and enrollment in our ReMEDy2 trial. We believe these conditions may be due to hospital and medical facility staffing shortages; inclusion/exclusion criteria in the study protocol; concerns managing logistics and protocol compliance for participants discharged from the hospital to an intermediate care facility; concerns regarding the prior clinically significant hypotension events and circumstances surrounding the previous clinical hold; use of artificial intelligence and telemedicine which have enabled smaller hospitals to retain AIS patients not eligible for mechanical thrombectomy instead of sending these patients to the larger stroke centers which are more likely to be sites in our trial; and competition for research staff and trial subjects due to other pending stroke and neurological trials. We continue to reach out to current and potential study sites to understand the specific issues at each study site. In an effort to mitigate the impact of these factors, we have significantly expanded our internal clinical team and have brought in-house certain trial activities, including site identification, qualification and activation, clinical site monitoring, supporting vendor management and overall program management. We continue to work closely with our contract research organizations and other supporting vendors to develop procedures to support both U.S. and global study sites and potential participants as needed. We intend to continue to monitor the results of these efforts and, if necessary, implement additional actions to enhance site activations and enrollment in our ReMEDy2 trial; however, no assurances can be provided as to the success of these actions and if or when these issues will resolve. Failure to resolve these issues may result in further delays in our ReMEDy2 trial and increase the difficulty in forecasting enrollment. We currently estimate that the interim analysis will be completed in the fourth quarter of 2026.

Our future success is dependent upon the success of our development efforts, our ability to demonstrate clinical progress for our DM199 product candidate in the United States or other markets, our ability, or the ability of any future partner, to obtain required governmental approvals of our product candidate, our ability to license or market and sell our DM199 product candidate and our ability to obtain additional financing to fund these efforts.

As of March 31, 2026, we have incurred losses of $182.8 million since our inception in 2000. For the three months ended March 31, 2026, we incurred a net loss of $10.0 million and negative cash flows from operating activities of $9.1 million. We expect to continue to incur substantial operating losses until such time as any future product sales, licensing fees, milestone payments and/or royalty payments generate revenue sufficient to fund our continuing operations. For the foreseeable future, we expect to incur significant operating losses as we continue the development and clinical study of, and to seek regulatory approval for, our DM199 product candidate. As of March 31, 2026, we had combined cash, cash equivalents and marketable securities of $51.3 million, working capital of $46.6 million and shareholders’ equity of $47.2 million.

Our principal source of cash has been net proceeds from the issuance of equity securities. Although we have previously been successful in obtaining financing through equity securities offerings, there is no assurance that we will be able to do so in the future. This is particularly true if our clinical data are not positive or if economic and market conditions deteriorate.

We expect that we will need substantial additional capital to further our research and development activities and complete the required clinical studies, regulatory activities and manufacturing development for our product candidate, DM199, or any future product candidates, to a point where they may be licensed or commercially sold. We expect our current cash, cash equivalents and marketable securities to be sufficient to fund our planned operations for at least the next 12 months from the date of issuance of these condensed consolidated financial statements. The amount and timing of our future funding requirements will depend on many factors, including timing and results of our ongoing development efforts, including our current ReMEDy2 trial and the rate of site activation and participant enrollment in the study; the Phase 2 PE trial; the potential expansion of our current development programs; the effects of ongoing site staffing shortages; and other factors on our clinical trials and our operating expenses. We may require significant additional funds earlier than we currently expect and there is no assurance that we will not need or seek additional funding prior to such time, especially if market conditions for raising capital are favorable.
