Explanatory Note
This Current Report on Form 8-K/A (“Amendment No. 1”) amends the Current Report on Form 8-K filed with the
Securities and Exchange Commission on March 27, 2027 (the “Initial Filing”) by Nuwellis, Inc. (the “Company”). This Amendment No.
1 is being filed pursuant to Item 5.02(a)(3)(iii) of Form 8-K in order to file as exhibits, supplemental letters received from each of Katharyn Field and Mika Grasso, former members of the Board of Directors of the Company (the “Board”), pursuant to the opportunity to respond to the Initial Filing granted to each of them under Item 5.02(a)(3)(ii) of Form 8-K. The information contained in this Amendment No. 1 supplements
the information contained in the Initial Filing.
| Item 5.02 |
Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
|
As previously disclosed in the Initial Filing, on March 26, 2026, each of Mika Grasso and Katharyn Field resigned, effective immediately, from the Board.
Copies of their resignation letters were attached as exhibits to the Initial Filing. On March 31, 2026, each of Katharyn Field and Mika Grasso provided supplemental letters to the Company’s Initial Filing (the “Response Letters”). The Response Letters are attached hereto as Exhibits 17.1 and 17.2, respectively.
The Company and the continuing members of the Board do not agree with certain statements made by Ms. Field and Mr. Grasso in the Response Letters and believe that the
Company’s description of the circumstances set forth in the Initial Filing is accurate.
CAUTIONARY NOTE
IN THE INTERESTS OF FULL AND COMPLETE DISCLOSURE, THE RESPONSE LETTERS DELIVERED BY MR. GRASSO AND MS. FIELD ARE BEING FILED IN EXACTLY THE FORM IN WHICH
THEY WERE PROVIDED TO THE COMPANY, WITHOUT REDACTION OR MODIFICATION OF ANY KIND. THE COMPANY WISHES TO EMPHASIZE THAT THE PREVIOUSLY FILED RESIGNATION LETTERS AND THE ATTACHED RESPONSE LETTERS REFLECT ONLY THE THOUGHTS AND BELIEFS OF MR. GRASSO AND
MS. FIELD, WHICH MAY OR MAY NOT CORRESPOND WITH THE THOUGHTS AND BELIEFS OF ANY REPRESENTATIVE OF THE COMPANY, AND MANY OF WHICH ARE EXPRESSLY CONTRARY TO THE THOUGHTS AND BELIEFS OF THE COMPANY’S MANAGEMENT AND THE BOARD AND TO THE FACTS RELEVANT TO
THE VARIOUS ISSUES. AS A RESULT, THE COMPANY TAKES NO RESPONSIBILITY FOR THE CONTENTS OF THE RESIGNATION LETTERS OR THE RESPONSE LETTERS, INCLUDING ANY RESPONSIBILITY THAT MAY ARISE IN CONNECTION WITH ANY OF THE FORWARD-LOOKING STATEMENTS CONTAINED
IN THE RESIGNATION LETTERS OR RESPONSE LETTERS. STOCKHOLDERS AND INVESTORS ARE STRONGLY ENCOURAGED TO RELY ONLY ON THE INFORMATION ABOUT THE COMPANY CONTAINED IN THE COMPANY’S FILINGS WITH THE SECURITIES AND EXCHANGE COMMISSION, INCLUDING THE
COMPANY’S MOST RECENT ANNUAL REPORT ON FORM 10-K, QUARTERLY REPORTS ON FORM 10-Q AND CURRENT REPORTS ON FORM 8-K.
