Nuwellis Pediatric Category Achieves Approximately 50% of Total U.S. Revenue in 2025, Marking Growth Milestone

Pediatric footprint expands to 47 centers nationwide, including six of the nation’s top 10 children’s hospitals

MINNEAPOLIS, March 31, 2026 (GLOBE NEWSWIRE) -- Nuwellis, Inc. (Nasdaq: NUWE), a medical technology company committed to delivering solutions for patients with cardiorenal conditions, announces continued momentum in its pediatric category, which is now the Company’s largest and fastest-growing category and represents approximately 50% of total U.S. revenue.

“Our pediatric category has become a meaningful and durable driver of growth, now accounting for approximately half of total revenue in 2025. This is a significant milestone as it both demonstrates the importance of the pediatric utilization of Aquadex, and the flexibility of the device across multiple patient demographics,” said Nuwellis’ CEO John Erb. “We are seeing strong utilization within established programs alongside growing interest from additional centers seeking precision fluid management solutions for complex pediatric patients.”

Nuwellis’ pediatric footprint has expanded to 47 centers nationwide, underscoring the category’s increasing strategic importance. The Company’s footprint includes six of the top 10 children’s hospitals as ranked by U.S. News & World Report, reinforcing the institutional credibility and clinical rigor underpinning hospital adoption.

Nuwellis’ Aquadex therapy platform, which is cleared by the Food and Drug Administration for use in pediatric and adult patients weighing 20kg and above, is designed to provide precise ultrafiltration tailored to small blood-volume patients, supporting clinicians in managing fluid overload in critically ill children. The Company believes continued pediatric expansion represents a strategic growth catalyst supported by high-acuity use cases, institutional adoption, and repeat utilization within established programs.

“Adoption within leading pediatric centers reflects the growing recognition of the need for precision fluid management in this vulnerable population,” added Nuwellis’ Senior Director of Medical Affairs Kelsey Newell. “We remain focused on supporting clinical evidence development and expanding market access.”

Nuwellis expects pediatric growth to remain a core component of its overall strategy as it advances its cardiorenal focus and deepens engagement within specialty centers of excellence.
