The information set forth under Item 5.02 of this Current Report on Form 8-K/A is incorporated into this Item 5.01 by reference.

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, Rick Sterling delivered to the Company a written notice of resignation from the Board of Directors of the Company (the “Board”), with such resignation to become effective contingent upon the satisfaction of certain conditions, including the filing of the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2025, and subject to the satisfaction of certain additional conditions, including the closing of the transactions contemplated by the applicable note purchase agreements and the placement or purchase of a customary directors’ and officers’ liability insurance tail policy (the “Sterling Resignation Notice”).

On March 31, 2026, the Company filed its Annual Report on Form 10-K for the fiscal year ended December 31, 2025. Pursuant to the express terms of the Sterling Resignation Notice, because the conditions to the effectiveness of Mr. Sterling’s resignation were not satisfied as of such date, the Sterling Resignation Notice was deemed withdrawn and of no further force or effect. There was no placement or purchase of a customary directors’ and officers’ liability insurance tail policy, as contemplated in the Sterling Resignation Notice. Accordingly, Mr. Sterling has not resigned from the Board and continues to serve as a director of the Company.

Mr. Sterling’s resignation notice was not submitted as the result of any disagreement with the Company on any matter relating to the Company’s 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.
