Item 5.02. Departure of Directors or Principal Officers; Election of Directors; Appointment of Principal Officers.

As previously reported by AquaBounty Technologies, Inc. (the "Company") in a Current Report on Form 8-K filed with the Securities and Exchange Commission on October 28, 2025 (the "Initial Form 8-K"), on October 28, 2025, Sylvia Wulf delivered to the Company a written notice of resignation from the Board of Directors (the "Board"), with such resignation to become effective solely upon the occurrence of certain conditions, including the earlier to occur of (a) the closing of certain specified transactions or (b) January 31, 2026, provided that her resignation would be effective only if a customary directors and officers insurance tail policy was in place or approved to be obtained (the "Wulf Resignation Notice").

Pursuant to its terms, the Wulf Resignation Notice expired on January 31, 2026 because the conditions to the effectiveness of Ms. Wulf's resignation were not satisfied. Therefore, Ms. Wulf has not resigned from the Board and continues to serve as a director of the Company.

Rick Sterling's notice of resignation (the "Sterling Resignation Notice"), which was also submitted on October 28, 2025, as previously disclosed in the Initial 8-K, remains in effect, subject to the satisfaction of certain conditions set forth in the Sterling Resignation Notice.

The resignation notices referenced above were not submitted as the result of any disagreement with the Company on any matter relating to its operations, policies, or practices.

Except as expressly set forth herein, this Current Report on Form 8-K/A does not amend the Initial 8-K in any way and does not modify or update any other disclosures contained in the Initial 8-K. This Current Report on Form 8-K/A supplements the Initial 8-K and should be read in conjunction with the Initial 8-K.
