“Our third quarter results reflect disciplined execution and meaningful progress toward building a more focused, U.S.-driven business,” said John Erb, Chairman and Chief Executive Officer of Nuwellis. “We continue to strengthen our leadership in precision fluid management across critical care, pediatrics, and hospital-based outpatient therapy. With the launch of our new 24-hour circuit and successful early hospital-based outpatient treatments, we are expanding how and where Aquadex therapy can be delivered to improve patient outcomes.”

Third Quarter 2025 Financial Results

Total revenue for the third quarter of 2025 was $2.2 million, compared to $2.4 million in the prior year quarter. On a pro-forma basis, revenue grew approximately 7% year-over-year, after excluding one-time SeaStar Medical revenue of $0.2 million in the prior year period and a $0.1 million decrease in international revenue due to the commencement of international wind-down activities in the third quarter.

Sequentially, revenue increased 29% from the second quarter, driven by higher consumable utilization and increased U.S. console placements.

Gross margin was 65.2%, compared to 70.0% in the prior year quarter, driven by unfavorable manufacturing utilization in the first half of fiscal year 2025, which was recognized in Costs of Sales in the third quarter.

Operating expenses totaled $4.1 million, up 30% year-over-year, reflecting increased investment in rebuilding the U.S. sales force to historical headcount levels and additional investments in sustaining engineering and quality systems.

Operating loss was $2.7 million, compared to $1.5 million last year.

The company ended the quarter with $3.1 million in cash and cash equivalents and remains debt-free.

About Nuwellis Nuwellis, Inc. (Nasdaq: NUWE) is a medical technology company advancing precision fluid management therapies to improve recovery and outcomes for cardiorenal syndrome patients. Through our Aquadex® SmartFlow system, we make fluid balance measurable, controllable, and consistent—supporting clinicians with technology designed for accuracy and confidence in care. Headquartered in Minneapolis, MN, with a wholly owned subsidiary in Ireland, Nuwellis is redefining the standard for fluid management. For more information visit www.nuwellis.com or visit us on LinkedIn or X, formerly known as Twitter.

About the Aquadex SmartFlow® System The Aquadex SmartFlow system delivers clinically proven therapy using a simple, flexible and smart method of removing excess fluid from patients suffering from hypervolemia (fluid overload). The Aquadex SmartFlow system is indicated for temporary (up to 8 hours) or extended (longer than 8 hours in patients who require hospitalization) use in adult and pediatric patients weighing 20 kg or more whose fluid overload is unresponsive to medical management, including diuretics. All treatments must be administered by a health care provider, within an outpatient or inpatient clinical setting, under physician prescription, both having received training in extracorporeal therapies.

About Vivian Vivian is a purpose-built pediatric CRRT system designed for neonates and children. The platform targets an extracorporeal blood volume of 29–67 mL and features integrated hematocrit and SvO₂ sensors for real-time monitoring. Vivian brings three therapies—Ultrafiltration (UF), Continuous Veno-Venous Hemofiltration (CVVH), and Continuous Veno-Venous Hemodialysis (CVVHD)—onto a single platform with closed-loop ultrafiltration control tailored to patient weight. A guided, clinician-informed interface with on-screen prompts streamlines setup and reduces training burden, while a 6-port circuit provides flexible vascular-access options. Intended for patients 2.5–20 kg, Vivian was developed with direct input from pediatric ICU and nephrology teams to prioritize safety, precision, and simplicity for the most fragile patients.

Disclaimer: Vivian is an investigational device, under development, and not available for sale. Features and specifications are subject to change.
