Rhea-AI Filing Summary

Nuwellis, Inc. reported first quarter 2026 results that show stronger sales but continued losses. Revenue for the quarter was $2.4 million, up from $1.9 million a year earlier, a 26% increase driven by growth across Pediatric, Adult Heart Failure, and Critical Care categories and higher Aquadex system placements and utilization.

Gross margin improved to 70.1%, reflecting better pricing, product mix, and use of contract manufacturing. Operating expenses rose to about $6.0 million from $4.1 million, mainly from higher sales headcount and compensation, leading to a net loss attributable to common shareholders of roughly $4.3 million.

As of March 31, 2026, Nuwellis reported no debt and cash, cash equivalents, and restricted cash of about $2.2 million. During the quarter, the company raised approximately $4.4 million net from an offering of common stock and warrants, while using about $3.1 million of cash in operating activities.

Insights

Revenue and margins improved, but losses and cash burn remain significant.

Nuwellis grew Q1 2026 revenue to $2.4M, up 26% year over year, with gross margin rising to 70.1%. Management cites broader category growth and stronger Aquadex utilization as they shift from a 2025 strategic reset toward commercial execution.

However, operating expenses expanded to $6.0M, driven by higher sales-related costs and increased R&D, pushing net loss to $4.3M. Cash, cash equivalents, and restricted cash were $2.2M as of March 31, 2026, after $3.1M was used in operating activities.

Financing activities provided $4.4M from an equity and warrant offering, offsetting operating cash outflows. Future disclosures in periodic reports may clarify whether revenue growth and margin gains can outpace spending and support the broader cardiorenal strategy, including contributions from the Rendiatech acquisition.

gross margin financial
"Gross margin for the first quarter of 2026 was 70.1%, a 14% increase to the prior-year quarter."
Gross margin is the difference between how much money a company makes from selling its products and how much it costs to produce them, expressed as a percentage of sales. It shows how efficiently a company is turning sales into profit before other expenses like marketing or salaries. Higher gross margin means the company keeps more money from each sale, which is a good sign of financial health.
Aquadex therapy financial
"growth in both system placements and utilization of Aquadex therapy."
Aquadex therapy is a medical device-based treatment that gently removes excess fluid from the bloodstream of patients, most often those with heart failure who retain fluid despite medicines. Think of it like a small, targeted pump that draws off surplus water from a flooded basement without disturbing the house’s other systems. Investors watch it because clinical results, regulatory approvals and insurance coverage determine how widely hospitals adopt the technology and how much revenue device makers can earn.
warrant liabilities financial
"Change in fair value of warrant liabilities | | | 26 |"
Warrant liabilities are the financial obligations a company records when it grants warrants—special rights allowing someone to buy shares at a set price in the future. If the warrants are expected to be exercised, they are treated as a liability because the company might need to deliver shares or cash later. This matters to investors because it affects the company’s reported financial health and the potential dilution of existing shares.
Series J Convertible Preferred Stock financial
"Series J Convertible Preferred Stock as of March 31, 2026 and December 31, 2025"
Series J convertible preferred stock is a specific class of preferred shares that gives holders priority on dividends and company assets but can be exchanged for common shares under set terms. Think of it like a special ticket that pays out before regular tickets and can be swapped for ordinary tickets later; this matters to investors because it affects income priority, potential ownership dilution when converted, and influence over company decisions.
deemed dividend financial
"Deemed dividend attributable to Series J Convertible Preferred Stock"
cardiorenal conditions medical
"a medical technology company committed to delivering solutions for patients with cardiorenal conditions"
Cardiorenal conditions are health problems in which the heart and kidneys affect each other’s function, so damage or stress in one organ can worsen the other—think of the heart as a pump and the kidneys as a filter in a shared system. Investors watch these conditions because they drive demand for drugs, medical devices and ongoing care, influence hospital and insurance costs, and can shape long-term revenue and regulatory risks in healthcare businesses.

Nuwellis, Inc.  Announces First Quarter 2026 Financial Results

MINNEAPOLIS – May 12, 2026 – Nuwellis, Inc. (Nasdaq: NUWE), a medical technology company committed to delivering solutions for patients with cardiorenal conditions, today reported financial results for the first quarter ended March 31, 2026.

First Quarter and Recent Highlights:

 •
Net sales were $2.4 million, a 26% increase compared to the prior-year period

•
Gross margin improved to 70.1%, reflecting improved pricing, product mix, and the transition to contract manufacturing

•
Completed the acquisition of Rendiatech, adding automated kidney-function monitoring capabilities to the Company’s product development portfolio

•
Appointed Carisa Schultz as Chief Financial Officer and Dr. Stuart L. Goldstein as Director of Clinical Strategy

•
Appointed Martin J. Emerson and reappointed David A. McDonald to the Board of Directors

•
Expanded commercial coverage with a new South Texas territory and the return of experienced sales leaders with deep Aquadex expertise

•
Received issuance of a new U.S. patent supporting advanced safety design for pediatric extracorporeal therapy

•
Received a Notice of Allowance from the U.S. Patent and Trademark Office for a new patent covering the Company’s novel dual-lumen midline catheter technology designed for use in ultrafiltration therapies

The first quarter marked an important step in Nuwellis’ transition from strategic reset to execution. The quarter demonstrated progress across the Company’s commercial, financial, and platform priorities, with stronger Aquadex performance, continued pediatric momentum, and further expansion of its broader cardiorenal strategy.

“Q1 showed that the strategic reset we made in 2025 is beginning to translate into a more focused and commercially disciplined company,” said John Erb, Chairman and Chief Executive Officer of Nuwellis. “We are concentrating our resources around the areas where Nuwellis has clear clinical relevance, existing customer traction, and a differentiated path to growth, while maintaining the financial discipline required to execute. Aquadex gives us the foundation, pediatrics gives us a distinct growth category, and Rendiatech expands our ability to think more broadly across the cardiorenal continuum.”

First Quarter 2026 Financial Results

Revenue for the first quarter of 2026 was $2.4 million, compared to $1.9 million in the prior-year quarter, a 26% increase over the prior year period.  Revenue growth in the first quarter was driven by continued expansion across all core categories, including Pediatric, Adult Heart Failure, and Critical Care, along with growth in both system placements and utilization of Aquadex therapy.

 
 
Gross margin for the first quarter of 2026 was 70.1%, a 14% increase to the prior-year quarter.  The gross margin improvement reflects improved pricing and product mix and switching to contract manufacturing.

Operating expenses for the first quarter of 2026 were approximately $6.0 million, compared to approximately $4.1 million in the prior-year quarter.  The increase is driven by increased sales headcount and compensation associated with increased sales.

Net loss attributable to common shareholders for the first quarter of 2026 was approximately $4.3 million.

On March 31, 2026, the Company had no debt and cash, cash equivalents, and restricted cash of approximately $2.2 million.
