MINNEAPOLIS, March 10, 2026 (GLOBE NEWSWIRE) -- Nuwellis, Inc. (NASDAQ:NUWE), a medical technology company committed to delivering solutions for patients with cardiorenal conditions, today reported financial results for the fourth quarter and full year ended December 31, 2025.

Fourth Quarter and Recent Highlights:

Fourth quarter revenue of $2.4 million, a 4% increase compared to the prior-year quarter and 9% increase sequentially.
208% increase in U.S. console sales in Q4 versus prior year quarter.
Heart Failure revenue increased 48% and Pediatrics increased 16% year-over-year in Q4.
Gross margin of 68.2% in Q4, compared to 58.4% in the prior-year quarter.
Closed a $5.0 million private placement and warrant inducement transaction in January 2026, strengthening the Company's capital position.
Appointed Carisa Schultz as Chief Financial Officer, effective February 2, 2026.
Executed a definitive stock purchase agreement to acquire Rendiatech, expanding the Company's cardiorenal portfolio.

"2025 was a year of structural change and strategic re-focus for Nuwellis," said John Erb, Chief Executive Officer of Nuwellis. "While full year revenue declined compared to 2024, fourth quarter results reflected stronger utilization trends and meaningful gross margin expansion. Throughout the year, we prioritized operational discipline, refined our commercial focus around the cardiorenal continuum, and strengthened the underlying foundation of the business."

"Additionally, we are entering 2026 with new momentum," Mr. Erb added, "including the execution of our agreement to acquire Rendiatech and the pending expansion of our portfolio, the appointment of a new Chief Financial Officer, and additional capital to support operations. As we look ahead, we remain focused on integrating the Rendiatech acquisition, progressing development of Vivian, our novel pediatric solution supported by NIH grant funding, and driving more consistent commercial execution and deeper utilization within targeted accounts."

Fourth Quarter 2025 Financial Results

Revenue for the fourth quarter of 2025 was $2.4 million, a 4% increase compared to the prior-year quarter and a 9% increase sequentially. The year-over-year increase was attributable to a 208% increase in U.S. console sales (8 units vs. 3), an 11% circuit average selling price increase, and a non-recurring 59% increase in international sales, reflecting customer last-time buys. Growth in Heart Failure and Pediatrics was partially offset by lower Critical Care revenue compared to the prior-year quarter.

Gross margin for the fourth quarter of 2025 was 68.2%, compared to 58.4% in the prior-year quarter. The gross margin improvement reflects improved pricing and product mix, partially offset by unfavorable manufacturing variances.

Operating expenses for the fourth quarter of 2025 were approximately $4.1 million, compared to approximately $3.7 million in the prior-year quarter.

Operating loss for the fourth quarter of 2025 was approximately $2.4 million, flat with the prior-year quarter.

Net loss attributable to common shareholders for the fourth quarter of 2025 was approximately $2.4 million.

Full Year 2025 Financial Results

Revenue for the full year ended December 31, 2025, was $8.3 million, a 5% decrease compared to the prior year. Heart Failure revenue increased 8% year-over-year, and Pediatrics increased 14%, while Critical Care declined 19%.

Gross margin as a percent of revenue for the full year was 62.0%, compared to 64.9% in the prior year.

Operating expenses for the full year were $16.2 million, $0.4 million lower than the prior year.

Net loss attributable to common shareholders for the full year was $17.5 million, which includes a $6.4 million non-cash warrant valuation expense and approximately $0.3 million in executive severance expense.

On December 31, 2025, the Company had no debt and cash, cash equivalents and restricted cash of approximately $1.2 million.
