DiaMedica Therapeutics Inc.

Although this Item 1A is not applicable to us as a smaller reporting company, we hereby disclose the following new risk factor in addition to those disclosed in our annual report on Form 10-K for the fiscal year ended December 31, 2024, and we hereby update the risk factors in our annual report on Form 10-K for the fiscal year ended December 31, 2024 to reflect our current expectations regarding the timing of the results from Part 1a of the pending safety, tolerability and pharmacodynamic, proof-of-concept Phase 2 study in preeclampsia patients to between the second half of June and the first half of July 2025.

Subsequent trials may fail to replicate promising data seen in earlier preclinical studies and clinical trials.

Interim data from the ongoing Part 1a portion of the investigator-sponsored Phase 2 study of DM199 for the treatment of preeclampsia provided promising results. However, these results may not be replicated in ongoing and future studies or trials, and the final data analysis may differ from interim data analysis.

Even if ongoing and future trials of DM199 are conducted and completed as planned, the results may not replicate the results seen in preclinical studies and early clinical studies or meet the primary or secondary endpoints, or otherwise not prove sufficient to obtain regulatory approval or result in a restricted product label that could negatively impact commercialization. Success in preclinical testing does not ensure success in clinical trials, and success in early stage clinical trials does not ensure success in later clinical trials. This can be due to a variety of reasons, including variations in patient populations, or the inability of certain patients to complete all assessments required by the clinical trial protocol, adjustments to clinical trial protocols or designs as compared to earlier testing or trials, variations in the data that could produce inconclusive or uninterpretable results, or the use of additional trial sites or investigators.

Furthermore, if we fail to replicate the promising results from our preclinical studies or clinical trials in ongoing or future clinical trials, we may be unable to successfully develop, obtain regulatory approval for and commercialize our current or future product candidates.

Changes in funding and staffing for the FDA, SEC and other government agencies could prevent our new products from being developed, approved or commercialized in a timely manner or otherwise prevent those agencies from performing normal functions upon which the operation of our business substantially relies and which could negatively impact our business.

The ability and propensity of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels; payment of user fees and reauthorization of user fee programs; staffing and other resource limitations; its ability to hire and retain key personnel; statutory, regulatory and policy changes; and other business disruptions. Average review times at the FDA and foreign regulatory authorities have fluctuated in recent years as a result. In addition, the funding of government agencies that support research and development activities that pertain to FDA review, such as research to understand new technologies or establish new standards, is subject to the political process, which is inherently fluid and unpredictable. Such government agencies also have been subject to reductions in funding and downsizing of agency staffing levels, which could materially impact our business and operations. The current U.S. Presidential administration has implemented or proposed policies that may affect the FDA review process, including efforts to downsize the federal workforce, remove job elimination protections for federal workers, limit certain communications, and potentially impact user fee reauthorization. If political pressure, global health concerns, or other factors prevent the FDA or other regulatory authorities from conducting their regular reviews or other regulatory activities, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business.

We did not sell any unregistered equity securities of our Company during the quarterly period ended June 30, 2025.
