Previous Acquisition Reports
| Date | Event | Sentiment | Move | Catalyst |
|---|---|---|---|---|
| Aug 19 | Acquisition LOI | Positive | -5.4% | Signed non-binding LOI to acquire Rendiatech’s renal monitoring platform. |
For acquisition-related news, the prior Rendiatech LOI was strategic but met with a negative price reaction, indicating some history of skeptical market responses to this theme.
Recent history shows Nuwellis advancing its cardiorenal platform with patents, pediatric initiatives, and operational shifts. An earlier Aug 19, 2025 letter of intent to acquire Rendiatech aimed to add FDA-cleared monitoring systems and broaden into continuous renal health monitoring, yet the stock fell 5.4%. Today’s definitive agreement continues that strategy, formalizing the previously signaled transaction.
Historical Comparison
In the past 6 months, NUWE issued 1 acquisition-themed update on Rendiatech, averaging a 5.4% move. Today’s definitive deal formalizes that earlier LOI-driven strategy.
The company progressed from a non-binding LOI toward Rendiatech in Aug 2025 to a definitive Securities Purchase Agreement, signaling continuation of the same cardiorenal platform strategy.
Market Pulse Summary
The stock moved +8.6% in the session following this news. A strong positive reaction aligns with the company’s ongoing shift toward a broader cardiorenal platform. The definitive Rendiatech deal builds directly on the prior LOI and extends Nuwellis beyond fluid removal into real-time renal monitoring. Investors could weigh how past acquisition news around Rendiatech saw a -5.4% move and consider financing, integration, and execution risks that might limit the durability of any sharp upside.

Transaction positions Nuwellis to expand into real-time kidney function monitoring and strengthen its long-term cardiorenal platform, subject to customary closing conditions
MINNEAPOLIS, Jan. 29, 2026 (GLOBE NEWSWIRE) -- Nuwellis, Inc. (Nasdaq: NUWE), a medical technology company focused on advancing precision cardiorenal care in critical care settings, today announced that it has entered into a Securities Purchase Agreement to acquire all of the issued and outstanding capital stock of Rendiatech Ltd., an Israeli-based medical technology company focused on automated kidney function monitoring. The transaction is expected to close following the satisfaction of customary closing conditions.
The Rendiatech securities purchase agreement represents a strategic expansion of Nuwellis’ portfolio beyond therapeutic fluid management into real-time renal diagnostics, reinforcing the company’s long-term vision to commercialize differentiated cardiorenal offerings that support earlier detection of kidney stress and more informed clinical decision-making in high-acuity care settings.
Rendiatech’s Clarity™ system is designed to provide automated, continuous renal monitoring through precise urine-output measurement, replacing manual collection and intermittent readings. Upon closing, Nuwellis expects that the addition of this technology will establish a foundation for future expansion into advanced urine-based analytics and broader kidney function assessment.
“This agreement represents an important step in advancing our cardiorenal strategy,” said John Erb, Chief Executive Officer of Nuwellis. “By entering into this transaction, we are positioning the company to extend our capabilities beyond therapeutic fluid removal and into real-time renal monitoring, which we believe is a natural and complementary evolution of our portfolio.”
Upon completion of the transaction, Nuwellis expects to leverage its existing commercial infrastructure, clinical relationships, and critical care expertise to support the integration and future development of Rendiatech’s technology, without the need to establish new sales channels.
The transaction has been approved by the boards of directors of both companies and is subject to customary closing conditions. Additional details regarding the Securities Purchase Agreement are included in a Current Report on Form 8-K filed with the Securities and Exchange Commission.
