E.F. Hutton Suit

As previously announced on February 26, 2026, E.F. Hutton & Co. (“Hutton”) filed a complaint against Nuwellis, Inc. (the “Company”) with the Supreme Court of the State of New York. The complaint alleged, among other things, that the Company breached its engagement letter with Hutton to act as its exclusive placement agent for one or more of the Company’s registered securities offerings. The complaint sought compensatory damages, punitive damages, interest, costs and attorneys’ fees.

On April 24, 2026, the Company entered into a Settlement Agreement and Release (the “Settlement Agreement”) with Hutton, whereby the Company agreed to pay $204,000 (the “Settlement Amount”) to Hutton within five days of execution of the Settlement Agreement. The Settlement Agreement contained no admission of liability, included a mutual release of all claims, and an agreement by Hutton to file a Stipulation of Dismissal with Prejudice within two days of receiving the Settlement Amount.
