#### 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

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

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

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

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

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

<br> • 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.
