#### Exhibit 99.1

#### Nuwellis, Inc. Reports Second Quarter 2025

#### Financial Results and Business Highlights

**Minneapolis, MN, August 14, 2025** (GLOBE NEWSWIRE) — Nuwellis, Inc. (Nasdaq: NUWE), a commercial-stage medical technology company dedicated to transforming care for fluid overload patients, today announced financial results for the second quarter ended June 30, 2025, and provided a business update.

#### Second Quarter 2025 and Recent Business Highlights

Nuwellis continued to advance its strategic realignment during the second quarter, sharpening focus on high-impact growth areas in pediatric and cardiac surgery care while laying the foundation for expansion in outpatient heart failure. Despite temporary revenue disruption related to an industry-wide sterilization vendor issue, the company took swift action to prioritize patient care, protect its most vulnerable populations, and ensure strong momentum entering the third quarter.

• Revenue of $1.7 million, compared to $2.2 million in Q2 2024

<br> • Pediatric category remains a key driver of sustained demand

<br> • Executed a transition plan to outsource manufacturing to KDI Precision Manufacturing

• Completed a $5 million gross capital raise during the quarter

<br> • Successfully grew to 47 pediatric centers that adopted Aquadex therapy as part of their fluid management apporach with the addition of two new centers across the Southeastern United States<br>

<br> • Expanded IP portfolio with granting of new U.S. patent covering the fluid bag design that passively drains once full<br>

"While we faced a temporary headwind this quarter due to a vendor issue, our response demonstrated the strength of our operational discipline and our commitment to patients," said John Erb, Chairman of the Board and CEO of Nuwellis. "We're entering the second half of the year with clear priorities, a sharpened focus on our core markets, and the confidence that we're executing on the right strategy to drive long-term growth."

#### Second Quarter 2025 Financial Results
Revenue for the second quarter of 2025 was $1.7 million, compared to $2.2 million in the second quarter of 2024. The year-over-year decline was primarily due to a product backorder caused by an industry-wide sterilization delay.

Gross margin was 55.5% in Q2 2025, compared to 67.2% in Q2 2024. The margin contraction was primarily driven by under-absorption of fixed overhead because of lower production volumes.

Selling, general and administrative (SG&A) expenses were $3.2 million, which is flat to Q2 2024. Research and development (R&D) expenses totaled $675K, compared to $558K in the same period last year.

Total operating expenses for the quarter were $3.9 million, a 2% increase over prior year.

Operating loss for the quarter was $2.9 million, compared to $2.3 million in Q2 2024.

------

Net loss attributable to common shareholders was $12.6 million, or a loss of $60.99 per basic and diluted share, compared to $7.7 million, or a loss of $791.82 per share in Q2 2024.

As of June 30, 2025, the company had $4.5 million in cash and cash equivalents and remained debt-free. Nuwellis completed a $5.0 million gross capital raise during the quarter.
