MINNEAPOLIS, Feb. 28, 2023 (GLOBE NEWSWIRE) -- Nuwellis, Inc. (Nasdaq: NUWE), a medical technology company focused on transforming the lives of people with fluid overload, today reported financial results for the fourth quarter and full year ended December 31, 2022.

  • Revenue of $2.3 million for the fourth quarter 2022, a 42% increase over the prior-year period. Full year revenue of $8.5 million, an 8% increase over 2021.
  • Gross margin of 56.9% in the fourth quarter 2022, an increase of 250 basis points from the same period last year. Full year 2022 gross margin of 55.7%, a decrease of 100 basis points from 2021.
  • By segment, fourth quarter 2022 revenue was led by Pediatrics, followed by Heart Failure and Critical Care, which increased approximately 92%, 47%, and 24% over the same period last year, respectively. Full year 2022 revenue by segment was led by Pediatrics and Heart Failure, which increased approximately 28% and 9%, respectively.
  • Entered into an exclusive U.S. license and distribution agreement for SeaStar Medical’s Selective Cytopheretic Device (SCD) for pediatric Acute Kidney Injury (AKI). Approximately 4,000 children with AKI who are at high risk of mortality require therapy annually.
  • Announced peer-reviewed publication of results from a 10-year, real-world retrospective study supporting lower heart failure hospitalizations and readmissions with Aquadex. Data demonstrated 81% lower heart failure hospitalizations per year and a 48% decrease in rehospitalizations at 30 days from the national average.
  • Announced peer-reviewed data demonstrating 71% survival with kidney replacement therapy using Aquadex in low birth-weight preterm neonates.
  • Announced AVOID-HF clinical study analysis demonstrating clinical data that strongly favored adjustable ultrafiltration using Aquadex over adjustable IV diuretics in reducing cardiovascular mortality and subsequent HF events when patients are unresponsive to diuretics treatment.
  • Continued site activations for the Company’s REVERSE-HF clinical trial, with nine sites activated to date, on track to complete twelve activations by the end of first quarter 2023.
  • Appointed Chief Medical Officer, John Jefferies, M.D., and Chief Financial Officer, Lynn Blake, to the Executive Leadership team.
  • Cash, cash equivalents, and marketable securities of $18.3 million and no debt as of December 31, 2022.

“2022 proved to be a year of growth for Nuwellis, with 42% year-over-year revenue growth in the fourth quarter and 8% revenue growth for the full year. In 2023, we remain focused on the execution of our key strategic growth initiatives, with targeted expansion of our commercial team, investments in market penetration initiatives, and leverage of our growing body of clinical evidence to drive continued sales momentum. We are committed to making Aquadex the standard of care for patients with fluid overload who are not responsive to diuretics and driving increased utilization of ultrafiltration therapy in 2023 and beyond,” said Nestor Jaramillo, President and CEO of Nuwellis.

Fourth Quarter 2022 Financial Results

Revenue for the fourth quarter of 2022 was $2.3 million, compared to $1.6 million in the prior-year period.

Gross margin was 56.9% for the fourth quarter of 2022, compared to 54.4% in the prior-year period, an increase of 250 basis points, resulting from increased sales volume.

Selling, general and administrative expenses for the fourth quarter of 2022 were $4.7 million, compared to $4.1 million in the prior-year period. The increase in SG&A was primarily due to higher professional service fees and variable compensation expense, balanced with continued spending vigilance.

Fourth quarter research and development expenses were $1.2 million, compared to $1.1 million in the fourth quarter of 2021, reflecting a slight increase in product development expenses.

Net loss for the fourth quarter of 2022 was $1.9 million, or a loss of $5.00 per basic and diluted common share, compared to a net loss of $4.3 million, or a loss of $41.09 per basic and diluted common share in the prior-year period. The current period net loss includes $2.6 million of Other Income related to the year-end revaluation of warrants issued in conjunction with the Company’s October financing.

At December 31, 2022, the Company had cash, cash equivalents, and marketable securities of approximately $18.3 million and no debt. Outstanding shares as of February 24 were approximately 1.2 million, reflecting the Company’s December reverse stock split and the exercise of warrants issued in conjunction with the Company’s October financing.
