Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

(a) On June 22, 2024, Russell Medford, Joseph Thomis, and James Xu resigned, effective immediately, from their positions as members of the Board of Directors (the “Board”) of ThermoGenesis Holdings, Inc. (the “Company”). At the time of his resignation, Dr. Medford served as the Chairman of the Governance and Nominating Committee, the Chairman of the Audit Committee, and a member of the Compensation Committee. At the time of his resignation, Dr. Thomis served as the Chairman of the Compensation Committee, a member of the Governance and Nominating Committee, and a member of the Audit Committee. At the time of his resignation, Mr. James Xu served as a member of the Governance and Nominating Committee.

Based on a resignation letter submitted to the Chairman of the Board and Chief Executive Officer of the Company, which is filed herewith as Exhibit 17.1, the Company believes that Dr. Medford and Dr. Thomis resigned due to their disagreement with Company policies and practices related to potential strategic transactions and decisions, including with respect to real and/or perceived conflicts of interest on the part of the Chairman of the Board and Chief Executive Officer of the Company and the dissolution of the Transaction Committee. Based on a follow-up resignation letter submitted by Mr. James Xu on June 24, 2024, and which is attached herewith as Exhibit 17.2, Mr. James Xu expressed potential disagreement with the conclusions, especially reasons for the resignation in the letter attached herewith as Exhibit 17.1 notwithstanding originally signing the letter attached as Exhibit 17.1.

The Company is providing a copy of the disclosures contained in this Current Report on Form 8-K to Dr. Medford, Dr. Thomis, and Mr. James Xu on the date on which this Current Report is being filed with the Securities and Exchange Commission. The Company is also providing each of Dr. Medford, Dr. Thomis, and Mr. James Xu with the opportunity to furnish the Company with a letter stating whether he agrees with the statements made by the Company in this Current Report and, if not, the respects in which he does not agree.
