Nuwellis (NUWE) filed its Q3 2025 10‑Q. Net sales were $2.217 million, down from $2.367 million a year ago, as lower console pricing and reduced international activity offset a 15% increase in circuit sales. Gross margin was 65.2% versus 70.0% last year. The company reported quarterly net income of $468,000, aided by a $3.161 million non‑cash gain from the change in fair value of warrant liabilities.
Year‑to‑date, net sales were $5.846 million versus $6.418 million and net loss was $15.099 million. Operating cash flow for the nine months was an outflow of $7.780 million. Cash and cash equivalents were $3.094 million as of September 30, 2025. Management states that existing capital resources are expected to support operations into the first quarter of 2026, while acknowledging “substantial doubt” about the ability to continue as a going concern.
During the quarter, Nuwellis closed a June public offering with approximately $5.0 million in gross proceeds, executed a 1‑for‑42 reverse stock split effective July 3, 2025, and launched an ATM program, selling 447,288 shares for about $1.9 million in net proceeds by September 30.

Nuwellis, Inc. filed a report noting that on November 12, 2025 it released a press release with its financial results for the three and nine months ended September 30, 2025. The press release is included as Exhibit 99.1 and is incorporated by reference. The company states that this financial information is being furnished under Item 2.02 of Form 8-K, rather than filed, which limits how it is treated under certain securities law liability provisions.

This intellectual property is described as supporting Nuwellis’ pediatric device, Vivian, which is in development, as well as future platform innovation.
Nuwellis announced that the National Institutes of Health awarded an approximately $3 million multi-year grant to Koronis Biomedical Technologies Corporation (KBT), its development partner.

The filing is brief and states the clearance date as August 21, 2025.
