Here are two brief analogies for Nuwellis (NUWE):

• Like Baxter International for advanced fluid management in critical care.
• Like Fresenius Medical Care for specialized fluid removal therapy beyond traditional dialysis.

• Aquadex SmartFlow System: A medical device used for therapeutic ultrafiltration to remove excess fluid from patients with fluid overload.
• Aquadex SmartFlow Consumables: Disposable kits, including blood circuit sets and cartridges, designed for single-patient use with the Aquadex SmartFlow System.

Nuwellis (symbol: NUWE) sells primarily to other companies. Its customer base consists of healthcare providers that utilize its Aquadex SmartFlow system for ultrafiltration therapy.

The company's primary customers are:

• Hospitals
• Healthcare Systems
• Specialized clinics (e.g., cardiology, critical care, nephrology)

Based on Nuwellis's publicly available financial disclosures, including its annual report (10-K filing for the year ended December 31, 2023), no single customer accounted for 10% or more of its total revenue during 2023 or 2022. Consequently, Nuwellis does not disclose specific major customer companies by name or symbol, as there are no individually identifiable customers meeting a typical "major customer" threshold in its public filings.

Nuwellis (symbol: NUWE) develops, manufactures, and commercializes medical devices for ultrafiltration therapy, primarily focusing on managing fluid overload in patients suffering from heart failure, critical care conditions, and pediatric care. The addressable markets for their main products, the Aquadex FlexFlow and Aquadex SmartFlow systems, can be best represented by the broader fluid management and fluid therapy markets, which encompass the treatment of fluid imbalances.

The global fluid management market is a significant addressable market for Nuwellis. In 2025, this market is projected to reach approximately USD 9.52 billion globally. It is anticipated to grow at a compound annual growth rate (CAGR) of 11.50% from 2025 to 2033, potentially reaching over USD 22.75 billion by 2033. North America is a major region within this market, holding a substantial share of over 37% of the global revenue, with an estimated market size of USD 3.52 billion in North America in 2025.

Another related market, the global fluid therapy market, was valued at USD 10.60 billion in 2024 and is expected to grow to USD 14.45 billion by 2030, at a CAGR of 6.4% from 2025 to 2030. North America also leads this market, contributing approximately 38% of the total revenue in 2024.

While specific market sizes for "medical ultrafiltration for fluid overload" are not individually broken out in the same detail as the broader fluid management or fluid therapy markets, Nuwellis's products directly address these needs within these larger contexts. The applications of Nuwellis's devices in heart failure, critical care, and pediatric fluid management contribute to these overall market figures. For instance, the congestive heart failure treatment devices market alone was estimated at USD 6.35 billion globally in 2025 and is projected to reach USD 8.95 billion by 2034. The global critical care devices market, another area Nuwellis serves, was estimated at USD 57.93 billion in 2023 and is anticipated to grow to approximately USD 95.17 billion by 2033. Similarly, the pediatric perfusion market, which involves managing fluid in children, was estimated at USD 579 million globally in 2023 and is expected to reach USD 1.06 billion by 2034.

Nuwellis (NUWE) anticipates several key drivers to fuel its revenue growth over the next two to three years:

1. Growth in the Pediatric Segment: Nuwellis has demonstrated consistent strength and strategic focus on its pediatric patient population. The company reported a 38% growth in pediatric revenue in the first quarter of 2025 and a 23% increase in the second quarter of 2025 compared to the prior year. This growth is supported by the expansion of Aquadex therapy to new pediatric centers and strong demand from existing hospital customers. Furthermore, Nuwellis has received a new U.S. patent for its Vivian™ Pediatric device, focused on safer and more precise ultrafiltration, and secured a $3 million NIH grant to accelerate its pediatric platform.
2. Expansion into Outpatient Heart Failure Treatment: A significant growth driver is the company's strategic pivot towards outpatient opportunities, particularly in heart failure treatment. This initiative is bolstered by a nearly four-fold increase in CMS reimbursement for Aquadex therapy in outpatient clinics, rising to $1,639 per day, effective January 2025. To support this expansion, Nuwellis introduced a new 24-hour Aquadex™ circuit designed for single-day outpatient sessions.
3. Increased Utilization of Consumables and U.S. Console Sales: Revenue growth is expected from the continued increase in the utilization of consumables and higher U.S. console sales. In the first quarter of 2025, a 4% increase in consumables utilization contributed to overall revenue growth, indicating a growing installed base and increased adoption of the Aquadex SmartFlow® System.
4. Strategic Focus on Core Markets and Operational Efficiencies: Nuwellis is sharpening its focus on high-impact growth areas, specifically pediatrics and cardiac surgery care. Alongside this strategic market focus, the company is transitioning its manufacturing operations to KDI Precision Manufacturing. This move is anticipated to generate operational efficiencies and cost savings over the next 12 months, which can be reinvested into growth initiatives.
