Conference call begins at 9:00 a.m. Eastern time today

MINNEAPOLIS, Aug. 13, 2026 (GLOBE NEWSWIRE) -- Nuwellis, Inc. (Nasdaq: NUWE), a medical technology company committed to delivering solutions for patients with cardiorenal conditions, today reported financial results for the three and six months ended June 30, 2026.

Second Quarter Results and Recent Highlights:

• Net sales were $2.0 million in the second quarter, a 14% increase compared with the prior-year period; U.S. revenue increased 17%
• Net sales for the first six months of 2026 were $4.4 million, a 20% increase compared with the prior-year period; U.S. revenue increased 24%
• Gross margin in the second quarter improved to 76%, compared with 56% in the prior-year quarter, reflecting improved pricing, product mix, and the transition to contract manufacturing
• Sold nine consoles during the second quarter and 24 during the first half of 2026, compared with five during the first half of 2025, expanding the installed base for future circuit utilization
• First-half revenue increased across all core customer categories compared with the prior-year period, led by a 29% increase in pediatrics, 28% in critical care, and 27% in heart failure. U.S. revenue growth outpaced the total Company average, which included lower international, service, and rental revenue.
• Raised $6.0 million in gross proceeds through a June registered direct offering
• Subsequent to June 30, 2026, raised approximately $6.7 million in gross proceeds from a July financing and warrant exercises, strengthening the Company’s cash position and simplifying its capitalization structure
• Advanced the proposed Aquadex label expansion to patients weighing 5 kilograms or more, from patients weighing 20 kilograms or more, following a successful U.S. Food and Drug Administration pre-submission meeting
• Appointed Mike McCormick as President and Chief Executive Officer, effective June 30, 2026

The second quarter demonstrated continued year-over-year growth, meaningful gross-margin improvement and progress across Nuwellis’ commercial and strategic priorities. The Company enters its next phase focused on increasing the installed based and utilization of Aquadex, building recurring circuit revenue, expanding its position in pediatrics and critical care, and selectively advancing technologies that strengthen its broader cardiorenal platform.

“Nuwellis has an established commercial foundation with differentiated strength in pediatrics and momentum in critical care. Our straightforward objective is to grow recurring revenue, improve operating leverage, and position Nuwellis as the leading precision fluid management company across the cardiorenal continuum,” said Mike McCormick, Nuwellis President and Chief Executive Officer. “The recent infusion of capital strengthens our balance sheet and extends our cash runway, which provides financial flexibility to execute on our strategic priorities. We intend to concentrate our investments where we have clear clinical differentiation, attractive commercial opportunities, and the ability to generate sustainable shareholder value. As part of our strategic plan, we are evaluating opportunities to leverage our commercial infrastructure through complementary products and collaborations that deepen relationships within our existing hospital customers.”

Second Quarter 2026 Financial Results

Revenue for the second quarter of 2026 was $2.0 million, compared with approximately $1.7 million in the prior-year quarter, representing a 14% increase. The increase was driven by higher U.S. circuit and console sales, partially offset by lower technical services, catheter, and international sales.

The Company sold nine consoles during the second quarter, compared with three during the second quarter of 2025. The expanding installed base is expected to bolster growth in recurring circuit revenue, which remains the Company's primary driver of long-term growth.

U.S. circuit and console average selling prices increased approximately 5% and 3%, respectively, compared with the prior-year quarter, reflecting pricing adjustments implemented during the third quarter of 2025.

Gross margin for the second quarter of 2026 was 76%, compared with 56% in the prior-year quarter. The improvement reflected pricing adjustments implemented in 2025, favorable product mix, and our successful transition to contract manufacturing.

Operating expenses were approximately $4.7 million for the second quarter of 2026, compared with $3.9 million in the prior-year period, reflecting planned investments in commercial expansion and product development. Net loss was approximately $4.8 million, including approximately $1.7 million of non-cash warrant valuation expense associated with the June 2026 financing, compared with a net loss of $12.6 million in the prior-year quarter. Following the effective date of the Company’s most recent reverse stock split on July 2, 2026, the related warrants were reclassified from liability to equity in early July.

As of June 30, 2026, the Company had cash and cash equivalents of approximately $3.9 million. Through second-quarter financing activity and subsequent financing events, Nuwellis raised approximately $12.7 million in gross proceeds, strengthening its cash position and simplifying its capitalization structure. This activity included $6.0 million raised in June and, subsequent to June 30, an additional $3.4 million from a July financing and $3.3 million from warrant exercise proceeds.
