On August 19, 2025, Nuwellis, Inc. (the "***Company***") announced that it has entered into a non-binding letter of intent to acquire Rendiatech, Ltd., an Israeli-based medical device company specializing in real-time urine flow and acute kidney injury monitoring technologies. The proposed acquisition is expected to support the Company's strategy to expand its current technology platform beyond ultrafiltration by potentially adding continuous renal health monitoring technologies that provide clinicians with earlier insight into fluid status and kidney function. The parties are engaged in the due diligence process and should they agree to proceed, the transaction is anticipated to close in the fourth quarter of 2025, pending final Board approval and closing conditions.

#### Forward-Looking Statements
Certain statements in this Current Report on Form 8-K may be considered forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including without limitation, statements regarding the new market opportunities and anticipated growth in 2025 and beyond. Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Many factors could cause actual future events to differ materially from the forward-looking statements in this Current Report on Form 8-K, including, without limitation, those risks associated with our ability to execute on our commercialization strategy, the possibility that we may be unable to raise sufficient funds necessary for our anticipated operations, our post-market clinical data collection activities, benefits of our products to patients, our expectations with respect to product development and commercialization efforts, our ability to increase market and physician acceptance of our products, potentially competitive product offerings, intellectual property protection, our ability to integrate acquired businesses, our expectations regarding anticipated synergies with and benefits from acquired businesses, and other risks and uncertainties described in our filings with the SEC. Forward-looking statements speak only as of the date when made. The Company does not assume any obligation to publicly update or revise any forward-looking statements, whether due to new information, future events or otherwise.
