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 provided a business update and reported financial results for the second quarter ended June 30, 2026. Management will host a conference call Tuesday, August 11, 2026, at 8:00 AM Eastern Time / 7:00 AM Central Time to discuss its business update and second quarter 2026 financial results.

“With the recent positive interim results from Part 1a of our Phase 2 study evaluating DM199 in preeclampsia, we’re eager to continue advancement of this promising candidate to address ischemic diseases in the second half of this year,” said Rick Pauls, President and CEO of DiaMedica. “Preeclampsia, fetal growth restriction and stroke are areas with high unmet medical need due to the lack of approved treatment options, and we believe DM199 has the potential to provide a disease-modifying solution for patients suffering from these ischemic conditions. We look forward to sharing results of the recently completed first cohort of fetal growth restriction and initiating subsequent studies in the ongoing investigator-sponsored Phase 2, open label trial in these indications.”

“In Part 1a of the Phase 2 study evaluating DM199 in women with preeclampsia with expected delivery within 72 hours, the most clinically meaningful pharmacodynamic effects were observed in the mid-dose range, Cohorts 4 through 8, where patients showed reductions in both maternal blood pressure and uterine artery pulsatility index (PI). Reductions in PI are consistent with reduced uteroplacental vascular resistance, improved blood flow and the potential to modify the underlying disease process in these patient populations,” said Julie Krop, MD, Chief Medical Officer of DiaMedica. “These findings represent significant progress for our preeclampsia program as they support selection of the mid-dose range for further clinical evaluation in our early-onset preeclampsia and fetal growth restriction studies.”

Recent Corporate Highlights

• Fetal Growth Restriction (FGR) Phase 2 Update: Enrollment of the first of three planned cohorts has been completed, consisting of 6 participants at the 5 µg/kg dose level. This is the first time DM199 has been used to treat early-onset fetal growth restriction patients. A key opinion leader (KOL) call is being scheduled in September, with leading preeclampsia OBGYN and study Principal Investigator Dr. Cathy Cluver, to discuss the clinical case for DM199’s therapeutic potential in FGR and top line results from the first cohort.
• Preeclampsia (PE) Phase 2 Part 1a Topline Results: DM199 produced clinically meaningful and statistically significant, sustained reductions in maternal blood pressure in late-onset PE. In the combined final, highest-dose cohorts (n=15; cohort 10 and extension cohort), DM199 produced a mean 29.1 mmHg reduction in systolic blood pressure (SBP) from a baseline mean of 169.3 mmHg (p<0.001) and a 17.0 mmHg reduction in diastolic blood pressure (DBP) from a baseline mean of 103.7 mmHg (p<0.001) at the pre-specified time point of five minutes after completion of the IV infusion. SBP was maintained below 160 mmHg at all measured time points over 24 hours (p<0.01). The combined cohort consisted of 15 PE subjects, three from the initial dose escalation phase and 12 additional subjects enrolled in the extension cohort.
  
  Detailed Part 1a results, including pharmacokinetic and pharmacodynamic analyses, are expected to be presented at an upcoming medical conference and submitted for publication.
  
  DiaMedica is also preparing to initiate a concurrent open-label three dose Phase 2 study in early-onset preeclampsia in North America and the United Kingdom to further support Phase 3 dose selection.

• Acute Ischemic Stroke (AIS) ReMEDy2 Phase 2/3 Clinical Developments: Enrollment in the Company’s Phase 2/3 ReMEDy2 (the ReMEDy2 trial – NCT05065216) trial has surpassed 85% of the 200 participants required to trigger the prespecified interim analysis. The Company now has approximately 70 activated sites across the United States, Canada, the United Kingdom, and six European countries added earlier this year, and expects the interim analysis to read out in early 2027.
• Health Canada Authorizes Global Phase 2 Early-Onset Preeclampsia Study: Health Canada authorized initiation of the Company’s open-label, sequential-cohort Phase 2 dose-finding study in early-onset preeclampsia, designed to enroll approximately 30 PE patients across three dose levels informed by the Part 1a results. DiaMedica is working with sites in Canada and expects to dose its first patient in the fourth quarter of 2026, and is also preparing to expand the study to the United Kingdom later this year, subject to regulatory authorization and site readiness.
• U.S. Regulatory Update on IND Pathway: In June 2026, DiaMedica received written feedback from the FDA regarding the nonclinical reproductive toxicity information needed to support a U.S. IND application for DM199 in preeclampsia. Based on this feedback, the Company believes that the previously completed rat reproductive toxicity study may be adequate to support IND clearance, provided DiaMedica can demonstrate adequate DM199 exposure, enzymatic activity, and pharmacologic effect in rats. DiaMedica has initiated a rat pharmacokinetic and pharmacologic activity study and, once complete, plans to submit the data package to FDA for review.

Financial Results Highlights for the Quarter Ended June 30, 2026

• Cash Position and Runway – Cash, cash equivalents and short-term investments were $43.5 million as of June 30, 2026, compared to $59.9 million as of December 31, 2025. Current liabilities were $6.6 million as of June 30, 2026, resulting in working capital of $37.7 million, compared to current liabilities of $5.1 million and working capital of $55.5 million as of December 31, 2025. Based on its current plans, the Company anticipates its current cash, cash equivalents and short-term investments will enable the Company to fund its planned clinical studies and support corporate operations through 2027.
• Cash Flows – Net cash used in operating activities for the six months ended June 30, 2026 was $17.2 million compared to $14.7 million for the same period in 2025. The increase resulted primarily from the increased net loss, partially offset by changes in operating assets and liabilities during the current year period.
• Research and Development (R&D) – R&D expenses were $8.2 million and $16.1 million for the three and six months ended June 30, 2026, respectively, up from $5.8 million and $11.5 million for the three and six months ended June 30, 2025, respectively. The increases were due primarily to the expansion of the Company’s clinical team, its ongoing ReMEDy2 clinical trial, including its global expansion, costs related to additional reproductive toxicity testing performed in support of the Company’s preeclampsia program in the United States, increased manufacturing development activity, and increased non-cash share-based compensation. The Company expects R&D expenses to increase moderately in future periods relative to recent prior periods as it continues the ReMEDy2 trial, including its global expansion, and continues to expand its DM199 clinical development program into preeclampsia.
• General and Administrative (G&A) – G&A expenses were $2.3 million and $4.8 million for the three and six months ended June 30, 2026, respectively, up slightly from $2.2 million and $4.7 million for the three and six months ended June 30, 2025, respectively. The increase for the three-month period was driven primarily by increased non-cash share-based compensation and professional fees, while the increase for the six-month period resulted primarily from increased personnel costs incurred in conjunction with expanding our team, partially offset by a reduction in current-year legal and other professional fees. The Company expects G&A expenses to remain relatively steady in future periods compared to recent prior periods.
• Net Loss – Net losses were $10.1 million and $20.2 million for the three and six months ended June 30, 2026, respectively, up from $7.7 million and $15.4 million for the three and six months ended June 30, 2025, respectively.

About the Phase 2 IST of DM199 in Preeclampsia and Fetal Growth Restriction

The Phase 2 study is an open-label, single center, single-arm, safety and pharmacodynamic, proof-of-concept, investigator-sponsored trial 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 (Part 1a, Part 1b and Part 2) in PE and a single study in FGR. Part 1a has been completed; the FGR study has initiated enrollment, and its first cohort of 6 participants has been enrolled; and Parts 1b and 2 are expected to initiate in September or October of 2026, as follows:"

Preeclampsia (PE)

• Part 1a late-onset PE: dose-escalation study evaluating single intravenous (IV) / single subcutaneous (SC) DM199 doses in late-onset PE subjects enrolled within 72 hours of delivery, including a confirmatory extension cohort of up to 12 participants at the cohort 10 dose level, which was completed in June 2026.
• Part 1b late-onset PE: dose-expansion study evaluating continuous IV infusion in up to 30 late-onset PE subjects enrolled within 72 hours of delivery, using a dosing level identified in Part 1a; initial enrollment expected in September or October 2026.
• Part 2 early-onset PE: evaluation of repeated SC dosing of DM199 in up to 30 early-onset PE subjects until delivery (expectant management), using three dose levels at 5, 10 and up to 15 µg/kg. The dose for the third cohort will be between 1 and 15 µg/kg based on results from the first two cohorts; initial enrollment expected in September or October 2026.

Fetal Growth Restriction (FGR)

• Part 3 early-onset FGR: evaluating repeated SC dosing in up to 30 early-onset FGR subjects until delivery, using up to three dose levels initially based on Part 1a data; enrollment commenced in June 2026 and the first cohort of 6 participants has been enrolled. Dosing levels are at 5, 10 and up to 15 µg/kg. The dose for the third cohort will be between 1 and 15 µg/kg based on results from the first two cohorts.

About Fetal Growth Restriction

Fetal growth restriction (FGR) occurs when a fetus fails to reach its genetically determined growth potential in the womb, most commonly due to placental insufficiency. FGR affects an estimated 10% of pregnancies worldwide and is associated with significantly increased risks of stillbirth, preterm birth, and neonatal morbidity, as well as long-term neurodevelopmental, cardiovascular, and metabolic complications. In severe, early-onset cases, FGR often necessitates delivery before 32 weeks of gestation, when the risks of prematurity must be weighed against the dangers of continued growth restriction in utero. See the recently released white paper, “The Potential of DM199 to Treat Fetal Growth Restriction.”

About Preeclampsia

Preeclampsia is a serious pregnancy disorder that typically develops after the 20th week of gestation, characterized by high blood pressure and damage to organ systems, often the kidneys and liver. Affecting up to 8% of pregnancies worldwide, preeclampsia can pose significant risks to both the mother and baby, including risk of stroke, placental abruption, progression to eclampsia, premature delivery, and death. Preeclampsia occurs in two stages. First, in early pregnancy, the placenta fails to embed properly in the wall of the uterus, and the spiral arteries in the uterine wall that are supposed to dilate to promote healthy blood flow to the placenta do not widen. Stage 2 then occurs after 20 weeks of pregnancy as the placenta, which has been chronically starved of oxygen from the blood, begins to release noxious factors into the mother’s circulation, inflicting widespread damage to her blood vessels and causing systemic endothelial dysfunction. Symptoms may include severe headaches, vision changes, upper abdominal pain and swelling in the hands and face. Delivery of the baby, often very prematurely, is the only available option for stopping the progression of preeclampsia. Women who have had preeclampsia have three to four times the risk of high blood pressure and double the risk for heart disease and stroke.

About Acute Ischemic Stroke

Acute ischemic stroke (AIS) occurs when a blood clot blocks a vessel supplying blood to the brain, leading to a sudden loss of oxygen and nutrients and, if not corrected, ultimately neuronal cell death. According to the U.S. Center for Disease Control, stroke causes approximately one out of every 20 deaths in the U.S. each year, and nearly nine out of 10 strokes are ischemic. No new therapeutics have been approved for acute ischemic stroke in over 25 years. When a blood vessel in the brain becomes blocked during a stroke, a core area of the affected brain tissue will typically suffer a nearly complete loss of blood flow, while the surrounding area (the “ischemic penumbra”) receives only about 20-40% of normal blood flow. Cells in the core area are rapidly depleted of their oxygen and glucose stores, leading, often within minutes, to cell death. The cells in the penumbral area may remain viable for several hours but are eventually at risk of damage.
