Item 1.01. Entry into a Material Definitive Agreement.

On October 28, 2025, AquaBounty Technologies, Inc. (the "Company") entered into Note Purchase Agreements, each substantially in the form attached as Exhibit 10.1 attached hereto (the "Agreements" or "Note Purchase Agreements"), with certain investors (the "Investors"), providing for the issuance and sale of Senior Notes at par in an aggregate principal amount of $4,000,000 (the "Senior Notes") in a private placement transaction. The Senior Notes have the following characteristics and terms: (i) unsecured, (ii) nonconvertible, (iii) bear interest at 18% per annum, (iv) scheduled maturity date of 18 months from closing, and (v) principal and interest payable at maturity, or earlier if accelerated pursuant to an event of default. The Senior Notes provide for certain restrictive covenants of the Company, as well as events of default including, but not limited to, (a) non-payment, (b) breach of covenants, (c) insolvency, (d) unauthorized changes to board composition, (e) failure to maintain Nasdaq listing compliance, (f) delayed SEC filings, and (g) financial restatements with material adverse effect. Among other remedies, the Senior Notes provide the Investors the right to nominate an additional director to the Company's Board of Directors (the "Board") upon the occurrence of an event of default, subject to certain conditions. The Agreements required certain resignations from and appointments to the Board, as described in Item 5.02 below.

On October 28, 2025, the Investors funded the $4,000,000 payable under the Agreements to the Company, and the Company issued the Senior Notes to the Investors. The net proceeds from the issuance of the Senior Notes are expected to be used for general corporate purposes, including working capital and operational funding, as well as the repayment of certain debts.

In addition, on October 28, 2025, the Company entered into a placement agency agreement with Univest Securities, LLC ("Univest") to serve as the placement agent for the Senior Notes (the "Placement Agency Agreement"). Pursuant to the Placement Agency Agreement, the Company agreed to pay Univest a fee equal to 7.0% of the gross proceeds received from the sale of the Senior Notes, as well as up to $125,000 for out-of-pocket expenses, including reasonable fees and expenses of counsel.

The foregoing descriptions of (i) the Agreements and Senior Notes, and (ii) the Placement Agency Agreement do not purport to be complete and are qualified in their entirety by reference to the full text of such agreements, as set forth in Exhibits 10.1 and 10.2, respectively, each of which is incorporated herein by reference.
