SUPPLEMENT

TO

PROXY STATEMENT

FOR

ANNUAL MEETING OF STOCKHOLDERS

To Be Held on May 17, 2022

The date of this Supplement is May 16, 2022

On April 14, 2022, AquaBounty Technologies, Inc. (the “Company”) filed a proxy statement (the “Proxy Statement”) for its 2022 Annual Meeting of Stockholders (the “2022 Annual Meeting”), to be held on May 17, 2022, at 8:30 a.m. Eastern Time. The 2022 Annual Meeting will be held entirely online due to the continuing public health impact of the coronavirus (COVID-19) outbreak and to support the health and well-being of the Company’s partners, employees, and stockholders.

The Proxy Statement includes a proposal to amend the Company’s Third Amended and Restated Certificate of Incorporation, as amended (the “Charter”), to increase the number of authorized shares of the Company’s common stock, $0.001 par value per share (“Common Stock”) from 80,000,000 to 200,000,000.

On April 26, 2022, Institutional Shareholder Services Inc. (“ISS”) published a proxy analysis and vote recommendation for the 2022 Annual Meeting. The proposal to increase the Company’s authorized Common Stock received an unfavorable recommendation from ISS because ISS believes the proposed increase in the number of authorized shares of Common Stock is excessive and there is no specific risk of non-approval. After consideration of the recommendation by ISS, the Board of Directors of the Company unanimously approved, subject to stockholder approval, an amendment to the Charter (“Amendment”).

The Amendment would increase the authorized Common Stock from 80,000,000 shares to 150,000,000 shares. There would be no change in the number of authorized shares of preferred stock. The purpose of the Amendment is to give the Company the ability to raise capital necessary to continue and grow its operations. The full text of the Amendment, is attached hereto as Appendix A. As of the record date for the 2022 Annual Meeting, there were 71,109,701 shares of the Common Stock issued and outstanding.

Any vote “FOR,” “AGAINST” or “ABSTAIN” a proposal as described in the Proxy Statement using the proxy materials previously furnished by the Company (or a beneficial owner’s broker, bank, or other nominee) will continue to be counted as a vote “FOR” or “AGAINST” the proposal. If any stockholder has already returned his, her or its properly executed proxy card or voted via the internet or by telephone and would like to change his, her or its vote on any matter, such stockholder may revoke his, her or its proxy before it is voted at the 2022 Annual Meeting by submitting a later dated proxy card, by casting a subsequent vote via the Internet, or as otherwise described in the Proxy Statement.

YOUR VOTE IS VERY IMPORTANT. If you need assistance voting your shares, please call Georgeson LLC for assistance at +1-800-457-0759.

The information contained in this Supplement to the Proxy Statement modifies or supersedes any inconsistent information contained in the Proxy Statement. The information provided above may be deemed “additional soliciting materials” within the meaning of the Securities Exchange Act of 1934, as amended.
