PROSPECTUS SUPPLEMENT

(to Prospectus dated January 12, 2026)

1,269,509 Shares of Common Stock
Pre-Funded Warrants to Purchase up to 67,706 Shares of Common Stock (and 67,706 Shares of Common Stock underlying such Pre-Funded Warrants)

AQUABOUNTY TECHNOLOGIES, INC.

Pursuant to this prospectus supplement and the accompanying prospectus, AquaBounty Technologies, Inc. (the “Company,” “we,” “our” and “us”) is offering (i) 1,269,509 shares of common stock of the Company, par value $0.001 per share (the “common stock”), at a price of $0.86 per share, and (ii) 67,706 pre-funded warrants at a public offering price equal to the price per share being sold in this offering minus $0.001 to certain institutional accredited investors (the “Purchasers”). The pre-funded warrants will be exercisable immediately and may be exercised at any time until the pre-funded warrants are exercised in full. This offering also relates to the shares of common stock issuable upon exercise of the pre-funded warrants sold in this offering.

Our common stock is listed on the Nasdaq Capital Market (“Nasdaq”) under the symbol “AQB.” On February 11, 2026, the last reported sale price of our common stock on Nasdaq was US $0.88 per share.

We have retained Univest Securities, LLC (“Univest” or the “placement agent”) as our exclusive placement agent in connection with this offering. The placement agent is not purchasing or selling any of the securities offered pursuant to this prospectus supplement and the accompanying prospectus. See “Plan of Distribution” beginning on page S-8 of this prospectus supplement for more information regarding these arrangements.

Univest has agreed to use its “reasonable best efforts” to arrange for the sale of our common stock offered by this prospectus supplement and the accompanying prospectus, via a registered direct offering, but Univest has no obligation to purchase or sell any of such shares or to arrange for the purchase or sale of any specific number or dollar amount of such shares. There is no required minimum number of shares of our common stock that must be sold as a condition to completion of this offering. Because there is no minimum offering amount required as a condition to closing this offering, the actual offering amount, placement agent fees, and proceeds to us, if any, are not presently determinable and may be substantially less than the total maximum offering amounts set forth below.

The compensation to Univest for sales of common stock sold pursuant to the Securities Purchase Agreement will be a cash fee equal to seven percent (7%) of the aggregate gross proceeds received by the Company from this offering. We have agreed to provide reimbursement of the placement agent’s reasonable travel and other out-of-pocket expenses, including the reasonable fees, costs, and disbursements of its legal counsel, in an amount not to exceed an aggregate of $30,000. In connection with the sale of the common stock on our behalf, Univest may be deemed to be an underwriter within the meaning of Section 2(a)(11) of the Securities Act, and any fees or commissions received by it and any profit realized on the resale of securities sold by it while acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. We have also agreed to provide indemnification and contribution to Univest with respect to certain liabilities, including liabilities under the Securities Act or the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

The aggregate market value of the outstanding shares of our common stock held by non-affiliates is approximately $4,274,456.82, which was calculated in accordance with General Instruction I.B.6 of Form S-3 and is based on based on 3,877,695 shares of outstanding common stock, of which 3,850,862 shares are held by non-affiliates, and a price per share of $1.11, which was the closing price of our common stock on Nasdaq on January 23, 2026. During the prior 12-calendar-month period that ends on, and includes, the date of this prospectus, we have offered and sold no shares of common stock pursuant to General Instruction I.B.6 of Form S-3. Pursuant to General Instruction I.B.6 of Form S-3, in no event will we sell securities registered on this registration statement in a public

primary offering with a value exceeding more than one-third of our public float in any 12-month period so long as our public float remains below $75 million (the “Baby Shelf Limitation”). 

We are a smaller reporting company as defined under federal securities laws and, as such, may elect to comply with certain reduced public company reporting requirements for future filings. 

Investing in our securities involves a high degree of risk. See the section entitled “Risk Factors” beginning on Page S-4 of this prospectus supplement and in the documents incorporated by reference into this prospectus supplement for a discussion of risks that should be considered in connection with an investment in our securities.

TABLE OF CONTENTS

On December 23, 2025, we filed with the Securities Exchange Commission, or SEC, a registration statement on Form S-3 (as amended by the Amendment No. 1 to Form S-3, which was filed with the SEC on January 9, 2026), utilizing a shelf registration process relating to the securities further described in this prospectus supplement, which was declared effective by the SEC on January 12, 2026. Under the shelf registration process, we may, in one or more offerings, offer and sell any combination, together or separately, of our debt securities, common stock, preferred stock, depositary shares, warrants, purchase contracts and units, or any combination thereof as described in the accompanying base prospectus of up to $350,000,000 from time to time at prices to be determined by market conditions at the time of offering. We are selling shares of common stock and prefunded warrants, including the underlying shares of common stock issuable upon the exercise of the prefunded warrants in this offering.  

We provide information to you about this offering of shares of our common stock in two separate documents that are bound together: (1) this prospectus supplement, which describes the specific details regarding this offering and also adds to and updates information contained in the accompanying prospectus and the documents incorporated by reference into the prospectus supplement; and (2) the accompanying prospectus, which provides general information, some of which may not apply to this offering. Generally, when we refer to this “prospectus,” we are referring to both documents combined. You should read this entire prospectus supplement, as well as the accompanying prospectus and the documents incorporated by reference that are described under “Where You Can Find More Information” and “Incorporation of Certain Documents by Reference.”

If information in this prospectus supplement is inconsistent with the accompanying prospectus, you should rely on this prospectus supplement. However, if any statement in one of these documents is inconsistent with a statement in a document having a later date incorporated by reference in this prospectus, the statement in the document incorporated by reference modifies or supersedes the earlier statement as our business, financial condition, results of operations and prospects may have changed since the earlier dates.

You should rely only on the information contained in, or incorporated by reference into, this prospectus supplement, the accompanying prospectus, and in any free writing prospectus that we may authorize for use in connection with this offering. We have not authorized any other person to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. We are not making an offer to sell or soliciting an offer to buy our securities in any jurisdiction in which an offer or solicitation is not authorized or in which the person making that offer or solicitation is not qualified to do so or to anyone to whom it is unlawful to make an offer or solicitation. You should assume that the information appearing in this prospectus supplement, the prospectus, the documents incorporated by reference herein and therein, and in any free writing prospectus that we may authorize for use in connection with this offering, is accurate only as of the date of those respective documents. Our business, financial condition, results of operations and prospects may have changed since those dates. You should read this prospectus supplement, the prospectus, the documents incorporated by reference herein and therein, and any free writing prospectus that we may authorize for use in connection with this offering, in their entirety before making an investment decision.

We further note that the representations, warranties, and covenants made by us in any agreement that is filed as an exhibit to any document that is incorporated by reference in this prospectus supplement and the accompanying prospectus were made solely for the benefit of the parties to such agreement, including, in some cases, for the purpose of allocating risk among the parties to such agreements, and should not be deemed to be a representation, warranty or covenant to you unless you are a party to such agreement. Moreover, such representations, warranties, or covenants were accurate only as of the date when made or expressly referenced therein. Accordingly, such representations, warranties, and covenants should not be relied on as accurately representing the current state of our affairs unless you are a party to such agreement.

Certain statements contained in or incorporated by reference into this prospectus supplement, the accompanying base prospectus, our filings with the SEC and our public releases, including, but not limited to, information regarding the status and progress of our operating activities, the plans and objectives of our management, assumptions regarding our future performance and plans, and any financial guidance provided therein are forward-looking statements within the meaning of Section 27A(i) of the Securities Act of 1933 and Section 21E(i) of the Securities Exchange Act of 1934. The words “believe,” “may,” “will,” “estimate,” “continues,”

“anticipate,” “intend,” “foresee,” “expect,” “should,” “could,” “plan,” “predict,” “project,” or their negatives and similar expressions identify these forward-looking statements, although not all forward-looking statements contain these identifying words.

The forward-looking statements contained in prospectus supplement and the accompanying base prospectus are largely based on our expectations, which reflect estimates and assumptions made by our management. These estimates and assumptions reflect our best judgment based on currently known market conditions and other factors. Although we believe such estimates and assumptions to be reasonable, they are inherently uncertain and involve a number of risks and uncertainties that are beyond our control. In addition, management’s assumptions about future events may prove to be inaccurate. Management cautions all readers that the forward-looking statements contained in this prospectus supplement and the accompanying base prospectus are not guarantees of future performance, and we cannot assure any reader that such statements will be realized or the forward-looking events and circumstances will occur. Actual results may differ materially from those anticipated or implied in the forward-looking statements due to the factors listed in the “Risk Factors” section and elsewhere in this prospectus supplement and the accompanying base prospectus. These cautionary statements qualify all forward-looking statements attributable to us, or persons acting on our behalf. The risks, contingencies and uncertainties relate to, among other matters, the following: our history of net losses and the likelihood of future net losses; our ability to continue as a going concern; our ability to raise additional funds, including from the sale of non-current assets, in sufficient amounts on a timely basis, on acceptable terms, or at all; our ability to obtain and maintain approvals and permits to construct and operate the Ohio Farm Project (as defined below) without delay; risks related to potential strategic acquisitions, dispositions, mergers, joint ventures, and other strategic transactions; security breaches, cyber-attacks, and other disruptions could compromise our information, expose us to fraud or liability, or interrupt our operations; any further write-downs of the value of our assets; business, political, or economic disruptions or global health concerns; adverse developments affecting the financial services industry; our ability to use net operating losses and other tax attributes, which may be subject to certain limitations; volatility in the price of our shares of common stock; our ability to maintain our listing on Nasdaq; an active trading market for our common stock may not be sustained; our status as a “smaller reporting company” and a “non-accelerated filer” may cause our shares of common stock to be less attractive to investors; any issuance of preferred stock with terms that could dilute the voting power or reduce the value of our common stock; provisions in our corporate documents and Delaware law could have the effect of delaying, deferring, or preventing a change in control of us; our expectation of not paying cash dividends in the foreseeable future; the composition of our Board of Directors may change from time to time under our governing documents, including through the filling of vacancies, which may result in a change in the company’s strategic plan; other risks and uncertainties reported from time-to-time in AquaBounty’s filings with the SEC, including Part I item 1A “Risk Factors” of AquaBounty’s annual report on Form 10-K for the year ended December 31, 2024.

We also direct readers to the other risks and uncertainties discussed in other documents we file with the SEC.



The forward-looking statements made or incorporated by reference in this prospectus relate only to events as of the date on which the statements are made. We do not undertake any obligation to publicly update or review any forward-looking statement except as required by law, whether as a result of new information, future developments or otherwise.



If one or more of these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, our actual results may vary materially from what we may have expressed or implied by these forward-looking statements. We caution that you should not place undue reliance on any of our forward-looking statements. You should specifically consider the factors identified in this prospectus that could cause actual results to differ before making an investment decision to purchase our securities. Furthermore, new risks and uncertainties arise from time to time, and it is impossible for us to predict those events or how they may affect us.

This summary description about us and our business highlights selected information contained elsewhere in this prospectus supplement or incorporated in this prospectus supplement by reference. This summary does not contain all of the information you should consider before buying securities in this offering. You should carefully read this entire prospectus supplement, the accompanying prospectus, and any free writing prospectus, including each of the documents incorporated herein or therein by reference, before making an investment decision. Unless otherwise indicated or the context otherwise requires, references in this prospectus supplement to “AquaBounty Technologies, Inc.,”  the “Company,” “we,” “us,”  and “our”  refer to AquaBounty Technologies, Inc. and its subsidiaries.

AquaBounty was incorporated in December 1991 in the State of Delaware for the purpose of conducting research and development of the commercial viability of a group of proteins commonly known as antifreeze proteins. In 1996, we obtained the exclusive licensing rights for a gene construct (transgene) used to create a breed of farm-raised Atlantic salmon that exhibits growth rates that are substantially faster than conventional salmon. The Company historically pursued a growth strategy that included the construction of large-scale recirculating aquaculture system farms for producing genetically engineered Atlantic salmon (“GE Atlantic salmon”). The Company commenced construction of a 10,000 metric ton farm in Pioneer, Ohio (“Ohio Farm Project”), but paused the construction in June 2023, as the cost estimate to complete the farm continued to substantially increase due to inflation and other factors. Further, these cost increases impaired the Company’s ability to pursue municipal bond financing, which was a necessary component of its funding strategy. The Company subsequently engaged an investment bank to pursue a range of funding and strategic alternatives and to assist management in the prioritization of the Company’s core assets. These efforts resulted in the sale of the Company’s grow-out farm in Indiana in July 2024, recurring sales throughout the remainder of 2024 and the first nine months of 2025 of selected equipment originally intended for the Ohio Farm Project (“Ohio Equipment Assets”), and the sale of the Company’s Canadian subsidiary, including the broodstock farms owned by the Canadian subsidiary in Prince Edward Island, Canada and its intellectual property for GE Atlantic salmon, along with trademarks and patents in March 2025. After completion of these transactions, the Company’s primary remaining asset is its investment in the Ohio Farm Project, consisting of the remaining Ohio Equipment Assets and the land and construction in process. The Company continues to work with an investment bank to identify the optimal path forward for realizing the potential of this asset, either through new investment, partnership,  or other strategic options.

THE OFFERING



(1) Based on shares outstanding as of February 11, 2026,  excluding the following shares of common stock reserved for issuance as of that date.

 ● Stock options representing a total of 37,594 shares of common stock issuable upon exercise.

An investment in our common stock involves a high degree of risk. You should consider carefully the risks described below and discussed under the section captioned “Risk Factors” contained in our most recent Annual Report on Form 10-K, as revised or supplemented by our Quarterly Reports on Form 10-Q or Current Reports on Form 8-K since the filing of our most recent Annual Report on Form 10-K, each of which is incorporated by reference in this prospectus supplement in their entirety, together with other information in this prospectus supplement, and the information and documents incorporated by reference in this prospectus supplement and any accompanying base prospectus with respect to this offering filed by us with the SEC, before you make a decision to invest in our common stock. The risks and uncertainties described below are not the only ones we face. Other risks and uncertainties, including those that we do not currently consider material, may impair our business. If any of these risks actually occur, our business, financial condition, operating results or cash flows could be materially adversely affected. This could cause the trading price of our common stock to decline, resulting in a loss of all or part of your investment. Please also read “Cautionary Note Regarding Forward-Looking Statements” in this prospectus supplement.

This is a best efforts offering, with no minimum number of securities required to be sold, and we may sell fewer than all of the securities offered hereby.

The Placement Agent has agreed to use its reasonable best efforts to solicit offers to purchase the securities in this offering. The Placement Agent has no obligation to buy any of the securities from us or to arrange for the purchase or sale of any specific number or dollar amount of the securities. There is no required minimum number of securities that must be sold as a condition to completion of this offering, and there can be no assurance that the offering contemplated hereby will ultimately be consummated. Even if we sell securities offered hereby, because there is no minimum offering amount required as a condition to closing of this offering, the actual offering amount is not presently determinable and may be substantially less than the maximum amount set forth on the cover page of this prospectus supplement. We may sell fewer than all of the securities offered hereby, which may significantly reduce the amount of proceeds received by us. Thus, we may not raise the amount of capital we believe is required for our operations in the short term and may need to raise additional funds, which may not be available or available on terms acceptable to us.

There is no public market for the pre-funded warrants being offered in this offering.

There is no established public trading market for the pre-funded warrants being offered in this offering, and we do not expect a market to develop. In addition, we do not intend to apply to list the pre-funded warrants on any securities exchange or nationally recognized trading system, including Nasdaq. Without an active market, the liquidity of the pre-funded warrants will be limited.

Holders of pre-funded warrants purchased in this offering will have no rights as common stockholders until such holders exercise such pre-funded warrants and acquire our common stock.

Until holders of pre-funded warrants acquire shares of our common stock upon exercise of such pre-funded warrants, holders of pre-funded warrants will have no rights with respect to the shares of our common stock underlying such pre-funded warrants. Upon exercise of the pre-funded warrants, the holders will be entitled to exercise the rights of a common stockholder only as to matters for which the record date occurs after the exercise date.

You may experience significant dilution as a result of future financings and the exercise of outstanding options.

In order to raise additional capital, we may issue additional shares of our common stock or other securities convertible into or exchangeable for our common stock in future offerings pursuant to the accompanying prospectus. We cannot assure you that we will be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock or other securities convertible into or exchangeable for our common stock in future transactions may be higher or lower than the price per share in this offering.

Our stock price has been and is likely to be volatile.

The market price of our common stock has been and is likely to be subject to wide fluctuations. For example, the market price of our common stock has fluctuated from an intra-day low of $.50 to an intra-day high of $2.95 over the 12 months preceding the date of this prospectus supplement. This volatility may affect the price at which you could sell shares of our common stock, and the sale of substantial amounts of our common stock could adversely affect the price of our common stock. Our stock price is likely to continue to be volatile and subject to significant price and volume fluctuations in response to market and other factors, including, among other things those described elsewhere in this prospectus supplement, the accompanying prospectus, and the documents incorporated by reference herein and therein, and other factors beyond our control, such as fluctuations in the valuation of companies perceived by investors to be comparable to us. For example, announcements made by competitors regarding factors influencing their business may cause fluctuations in the valuation of companies throughout our industry, including fluctuations in the valuation of our stock.

Furthermore, the stock markets have experienced price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. These fluctuations often have been unrelated or disproportionate to the operating performance of those companies. These broad market and industry

fluctuations, as well as general economic, political and market conditions, such as recessions, interest rate changes or international currency fluctuations, may negatively affect the market price of our common stock.

We will have broad discretion in the use of the net proceeds from this offering and may allocate the net proceeds from this offering in ways that you and other stockholders may not approve.

Our management will have broad discretion in the use of the net proceeds, including for any of the purposes described in the section entitled “Use of Proceeds,” and you will not have the opportunity as part of your investment decision to assess whether the net proceeds are being used appropriately. Because of the number and variability of factors that will determine our use of the net proceeds from this offering, their ultimate use may vary substantially from their currently intended use. The failure of our management to use these funds effectively could have a material adverse effect on our business and cause the market price of our common stock to decline.

Future sales of our common stock in the public market or other financings could cause our stock price to fall.

Sales of a substantial number of shares of our common stock in the public market, and the perception that such sales might occur in the future or the occurrence of other financings, could depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. A substantial majority of the outstanding shares of our common stock are, and all of the shares sold in this offering upon issuance will be, freely tradable without restriction or further registration under the Securities Act of 1933, as amended (the “Securities Act”), unless these shares are owned or purchased by “affiliates” as that term is defined in Rule 144 under the Securities Act (“Rule 144”). In addition, shares of common stock issuable upon exercise of outstanding options, restricted stock units and shares reserved for future issuance under our incentive stock plan will be eligible for sale in the public market to the extent permitted by applicable vesting requirements and, in some cases, subject to compliance with the requirements of Rule 144. As a result, these shares can be freely sold in the public market upon issuance, subject to restrictions under the securities laws.

Because we do not intend to declare cash dividends on our shares of common stock in the foreseeable future, stockholders must rely on appreciation of the value of our common stock for any return on their investment.

We have never declared or paid cash dividends on our common stock and do not anticipate declaring or paying any cash dividends in the foreseeable future. In addition, the terms of our existing debt agreements preclude us from paying dividends. As a result, we expect that only appreciation of the price of our common stock, if any, will provide a return to investors in this offering for the foreseeable future.

We estimate the net proceeds to us from the sale of our common stock in this offering will be approximately $1.0 million after deducting the placement agent fees and estimated offering expenses payable by us.

We intend to use the net proceeds from this offering for general corporate purposes, which may include, among other things, capital expenditures and working capital. We have no present plans, agreements or commitments with respect to any potential acquisition. We currently do not intend to use any of the net proceeds from this offering to re-start construction of the Ohio Farm Project.

Investors are cautioned, however, that expenditures may vary substantially from these uses. Investors will be relying on the judgment of our management, who will have broad discretion regarding the application of the proceeds of this offering. The amounts and timing of our actual expenditures will depend upon numerous factors, including the amount of cash generated by our operations, if any, competition and other operational factors. We may find it necessary or advisable to use portions of the proceeds from this offering for other purposes.

We have never declared or paid any cash dividend on our capital stock. We currently intend to retain any future earnings and do not expect to pay any dividends in the foreseeable future. Any determination to declare or pay dividends in the future will be at the discretion of our board of directors and will depend on a number of factors, including our financial condition, operating results, capital requirements, general business conditions, and other factors that our board of directors may deem relevant.

We are offering shares of our common stock and pre-funded warrants in this offering. The following description of our common stock and pre-funded warrants summarizes the material terms and provisions thereof, including the material terms of the common stock and pre-funded warrants we are offering under this prospectus supplement and the accompanying base prospectus.

See “Description of Common and Preferred Stock” in the accompanying base prospectus for more information regarding our shares of common stock.

The following summary of certain terms and provisions of the pre-funded warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the pre-funded warrants, the form of which was filed as an exhibit to our Current Report on Form 8-K filed with the SEC on February 12, 2026. Prospective investors should carefully review the terms and provisions of the form of pre-funded warrant for a complete description of the terms and conditions of the pre-funded warrants.

Duration and Exercise Price

. Each pre-funded warrant offered hereby has an initial exercise price per share equal to $0.001. The pre-funded warrants are immediately exercisable and may be exercised at any time until the pre-funded warrants are exercised in full. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock and the exercise price.

Exercisability

. The pre-funded warrants are exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of the pre-funded warrant to the extent that the holder would own more than 4.99% of the outstanding common stock (or, at the election of the purchaser, 9.99%). No fractional shares of common stock will be issued in connection with the exercise of a pre-funded warrant. In lieu of fractional shares, we will pay cash or round up to the next whole share.

Cashless Exercise

. If at the time of exercise under the pre-funded warrant, there is no effective registration statement registering, or the prospectus contained therein is not available for the issuance of, the shares of common stock pursuant to the warrant, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common stock determined according to a formula set forth in the pre-funded warrants.

Transferability

. Subject to applicable laws, a pre-funded warrant may be transferred at the option of the holder upon surrender of the pre-funded warrant to us together with the appropriate instruments of transfer.

Exchange Listing

. There is no trading market available for the pre-funded warrants on any securities exchange or nationally recognized trading system. We do not intend to list the pre-funded warrants on any securities exchange or nationally recognized trading system.

Rights as a Stockholder

. Except as otherwise provided in the pre-funded warrants or by virtue of such holder’s ownership of shares of our common stock, the holders of the pre-funded warrants do not have the rights or privileges of holders of our common stock, including any voting rights, until they exercise their pre-funded warrants.

Fundamental Transaction

. In the event of a fundamental transaction, as described in the pre-funded warrants and generally including any reorganization, recapitalization or reclassification of our common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, or the acquisition of more than 50% of our outstanding common stock, the holders of the pre-funded warrants will be entitled to receive upon exercise of the pre-funded warrants the kind and amount of securities of the successor or acquiring corporation or of ours, if we are the surviving corporation, or any additional consideration that the holders would have received had they exercised the pre-funded warrants immediately prior to such fundamental transaction.

Univest Securities, LLC (the “placement agent” or “Univest”) has agreed to act as the exclusive placement agent in connection with this offering. The placement agent is not purchasing or selling the securities offered by this prospectus supplement, nor is the placement agent required to arrange the purchase or sale of any specific number or dollar amount of securities, but has agreed to use its reasonable best efforts to arrange for the sale of all of the securities offered hereby. 

We entered into securities purchase agreements directly with the investors on February 11, 2026 pursuant to which we will sell to the investors (i) 1,269,509 shares of common stock at a purchase price of $0.86 per share and (ii) pre-funded warrants to purchase 67,706 shares of common stock at a purchase price of $0.859 per pre-funded warrant in this takedown offering from our shelf registration statement, and we will only sell to investors who have entered into the securities purchase agreement.

We expect to deliver the common stock being offered pursuant to this prospectus supplement on or about February 13, 2026, subject to customary closing conditions.

The placement agent may be deemed to be an underwriter within the meaning of Section 2(a)(11) of the Securities Act, and any fees or commissions received by it and any profit realized on the resale of securities sold by it while acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. As an underwriter, the placement agent is required to comply with the requirements of the Securities Act and the Exchange Act, including, without limitation, Rule 415(a)(4) under the Securities Act and Rule 10b-5 and Regulation M under the Exchange Act. These rules and regulations may limit the timing of purchases and sales of our common stock by the placement agent. Under these rules and regulations, the placement agent:

From time to time in the common course of their respective businesses, the placement agent or its affiliates may in the future engage in investment banking and/or other services with us and our affiliates for which it may in the future receive customary fees and expenses.

We have agreed to pay the placement agent placement agent fees equal to seven percent 7.0% of the gross proceeds of this offering. In addition, we have agreed to reimburse the placement agent for all reasonable travel and other out-of-pocket expenses, including the reasonable fees, costs, and disbursements of its legal counsel, in an amount not to exceed an aggregate of $30,000. The Company will reimburse the placement agent at the closing of this offering, directly out of the gross proceeds raised in this offering. After deducting certain fees and expenses due to placement agent and our estimated offering expenses, we expect the net proceeds from this offering to be approximately US $1.0 million.

If within twelve (12) months after the later of the closing of this offering, or if the closing does not occur, the termination of the placement agency agreement entered into by and between the Company and the placement agent, dated February 11, 2026 (the “Placement Agency Agreement”) by the Company other than for cause, the Company completes the sale of any equity, debt and/or equity derivative instruments to any investors previously unknown to the Company who are actually introduced by the placement agent to the Company, during such period, then the Company shall pay to the placement agent a commission of seven percent  (7%) of the aggregate gross proceeds raised from such investors. The placement agent shall provide a list of such investors upon termination of the Placement Agency Agreement or closing of this offering, and the Company shall be able to review and revise this list as needed.

The offering price of the securities we are offering was negotiated between us and the investors, in consultation with the placement agent based on the trading of our common stock prior to the offering, among other things. Other factors considered in determining the offering price of the securities we are offering include our history and prospects, the stage of development of our business, our business plans for the future and the extent to which they have been implemented, an assessment of our management, general conditions of the securities markets at the time of the offering and such other factors as were deemed relevant.

The prospectus supplement or free writing prospectus may add, update or change information contained in this prospectus. If there is any inconsistency between the information in this prospectus and any prospectus supplement or free writing prospectus, you should rely on the information in the prospectus supplement or free writing prospectus, as applicable. You should read both this prospectus and any prospectus supplement and/or free writing prospectus together with additional information described under the headings “Where You Can Find More Information” and “Incorporation of Certain Documents by Reference.”



You should only rely on the information contained or incorporated by reference in this prospectus. We have not have authorized anyone to provide you with different information.

This prospectus contains or incorporates by reference certain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are not statements of historical fact but instead represent only management’s current beliefs regarding future events. By their nature, forward-looking statements are subject to risks, uncertainties, assumptions, and other important factors that may cause actual results, performance or achievements to differ materially from those expressed in or implied by such forward-looking statements. We caution you not to place undue reliance on these forward-looking statements, which speak only as of the date they were made. We do not undertake any obligation to update or revise these forward-looking statements to reflect events or circumstances after the date of this prospectus or to reflect the occurrence of unanticipated events or the non-occurrence of anticipated events, whether as a result of new information, future developments, or otherwise, except as required by law. Forward-looking statements include, without limitation, statements concerning future plans, objectives, goals, projections, strategies, events, or performance, and underlying assumptions and other statements related thereto. Statements preceded by, followed by or that otherwise include the words “anticipates,” “appears,” “are likely,” “believes,” “estimates,” “expects,” “foresees,” “intends,” “plans,” “projects,” and similar expressions or future or conditional verbs such as “would,” “should,” “could,” “may,” or “will” are intended to identify forward-looking statements. As set forth more fully under “Part I, Item 1A. Risk Factors” in the Company’s most recent Annual Report on Form 10-K and any subsequent combined Quarterly Reports on Form 10-Q, each of which is incorporated by reference herein, important factors that could cause actual results, performance, or achievements to differ materially from those expressed in or implied by forward-looking statements include, without limitation, the following:



We also direct readers to the other risks and uncertainties discussed in other documents we file with the SEC.



The forward-looking statements made or incorporated by reference in this prospectus relate only to events as of the date on which the statements are made. We do not undertake any obligation to publicly update or review any forward-looking statement except as required by law, whether as a result of new information, future developments or otherwise.



If one or more of these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, our actual results may vary materially from what we may have expressed or implied by these forward-looking statements. We caution that you should not place undue reliance on any of our forward-looking statements. You should specifically consider the factors identified in this prospectus that could cause actual results to differ before making an investment decision to purchase our securities. Furthermore, new risks and uncertainties arise from time to time, and it is impossible for us to predict those events or how they may affect us.



AquaBounty was incorporated in December 1991 in the State of Delaware for the purpose of conducting research and development of the commercial viability of a group of proteins commonly known as antifreeze proteins. In 1996, we obtained the exclusive licensing rights for a gene construct (transgene) used to create a breed of farm-raised Atlantic salmon that exhibits growth rates that are substantially faster than conventional salmon. The Company historically pursued a growth strategy that included the construction of large-scale recirculating aquaculture system farms for producing its genetically engineered Atlantic salmon (“GE Atlantic salmon”). The Company commenced construction of a 10,000 metric ton farm in Pioneer, Ohio (“Ohio Farm Project”), but paused the construction in June 2023, as the cost estimate to complete the farm continued to substantially increase due to inflation and other factors. Further, these cost increases impaired the Company’s ability to pursue municipal bond financing, which was a necessary component of its funding strategy. The Company subsequently engaged an investment bank to pursue a range of funding and strategic alternatives and to assist management in the prioritization of the Company’s core assets. These efforts resulted in the sale of the Company’s grow-out farm in Indiana in July

---

 

2024, recurring sales throughout the remainder of 2024 and the first nine months of 2025 of selected equipment originally intended for the Ohio Farm Project (“Ohio Equipment Assets”), and the sale of the Company’s Canadian subsidiary, including the broodstock farms owned by the Canadian subsidiary in Prince Edward Island, Canada and its intellectual property for GE Atlantic salmon, along with trademarks and patents in March 2025. After completion of these transactions, the Company’s primary remaining asset is its investment in the Ohio Farm Project, consisting of the remaining Ohio Equipment Assets and the land and construction in process. The Company continues to work with its investment bank to identify the optimal path forward for realizing the potential of this asset, either through new investment, partnership or other strategic options.

AquaBounty’s common stock is traded on Nasdaq under the symbol “AQB.”



Our executive offices are located at 233 Ayer Road, Suite 4,  Harvard, Massachusetts 01451. Our telephone number is (978) 648-6000. Our website address is https://aquabounty.com. The information on our website is not part of this prospectus and is not incorporated into this prospectus or any accompanying prospectus supplement by reference.



Before you invest in any of our securities, in addition to the other information in this prospectus and any prospectus supplement or other offering materials, you should carefully consider the risk factors in any prospectus supplement as well as the risk factors discussed under “Part I, Item 1A. Risk Factors” in the Company’s most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q which are incorporated by reference into this prospectus and any prospectus supplement, as the same may be amended, supplemented or superseded from time to time by our filings under Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act. These risks could materially and adversely affect our business, operating results, cash flows and financial condition and could result in a partial or complete loss of your investment. See “Incorporation of Certain Documents By Reference” and “Cautionary Statement Regarding Forward-Looking Statements.”



Unless otherwise indicated in the applicable prospectus supplement or other offering material, we will use the net proceeds from any sale of securities for general corporate purposes, which may include, among other things, repayment of debt, capital expenditures and working capital requirements. The net proceeds may be invested temporarily in short-term marketable securities or applied to repay short-term debt until they are used for their stated purpose.



We have not yet determined the amount or timing of the expenditures for each of the categories listed above and these expenditures may vary significantly depending on a variety of factors. As a result, unless otherwise indicated in the applicable prospectus supplement, our management will retain broad discretion in the allocation and use of the net proceeds of this offering.



We may offer from time to time debt securities in the form of either senior debt securities or subordinated debt securities. Unless otherwise specified in a prospectus supplement, the debt securities will be our direct, unsecured obligations and will rank equally with all of our other unsecured and unsubordinated indebtedness. We will issue debt securities under one or more separate indentures between us and a trustee to be identified in the applicable prospectus supplement.



The following summary of the general terms and provisions of the indenture is not complete (the text below refers to both indentures as the form of  “indenture”). Forms of indentures for senior indebtedness and subordinated indebtedness are included as exhibits to the registration statement of which this prospectus forms a part. The indentures are substantially identical except as described below under “Subordinated Debt Securities” in this section. You should read the indentures for provisions that may be important to you.

When we offer to sell a particular series of debt securities, the prospectus supplement will describe the specific terms of the series, and it will also address whether the general terms and provisions described below apply to the particular series of debt securities. Capitalized terms used in the summary have the meanings specified in the forms of indenture.



Unless otherwise provided in a supplemental indenture, our Board of Directors will set the particular terms of each series of debt securities, which will be described in a prospectus supplement relating to such series. We can issue an unlimited amount of debt securities under the indenture, in one or more series with the same or various maturities, at par, at a premium or at a discount. Among other things, the prospectus supplement relating to a series of debt securities being offered will address the following terms of the debt securities:

 

 

 

 





 

 

 

 





 



 

 

 



 

In addition, we may issue convertible debt securities. Any conversion provisions of a particular series of debt securities will be set forth in the officer’s certificate or supplemental indenture related to that series of debt securities and will be described in the relevant prospectus supplement. To the extent applicable, conversion may be mandatory, at the option of the holder or at our option, in which case the number of shares of common or preferred stock to be received upon conversion would be calculated as of a time and in the manner stated in the prospectus supplement.

 

The applicable prospectus supplement will provide an overview of the U.S. federal income tax considerations and other special considerations applicable to any debt securities we offer for sale.

 

As described in the applicable prospectus supplement, each debt security will be represented by either a certificate issued in definitive registered form (we will refer to any debt security represented by a certificated security as a “certificated debt security”) or one or more global securities registered in the name of a depositary, or its nominee (we will refer to any debt security represented by a global debt security as a “book-entry debt security”), in the aggregate principal amount of the series of debt securities. Except as described below under the heading “Global Debt Securities and Book-Entry System,” book-entry debt securities will not be certificated.

 

You can transfer certificated debt securities (and the right to receive the principal of, premium and interest thereon) only by surrendering the certificate representing those certificated debt securities. Either we or the trustee will reissue the existing certificate, or issue a new certificate, to the new holder.

 

You may transfer or exchange certificated debt securities at any office we maintain for this purpose in accordance with the terms of the indenture. There is no service charge, but we may require payment of a sum sufficient to cover any taxes or other governmental charges payable in connection with a transfer or exchange.

 

Each global debt security representing book-entry debt securities will be deposited with, or on behalf of, The Depository Trust Company (which we refer to below as “DTC” or the “depositary”), as the depositary, and registered in its (or its nominee’s) name. DTC is a limited-purpose trust company and a “banking organization” organized under New York law, a member of the Federal Reserve System, a “clearing corporation” within in the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to Section 17A of the Exchange Act. We understand that DTC intends to follow the following procedures with respect to book-entry debt securities.



Ownership of beneficial interests in book-entry debt securities will be limited to “participants” or persons that may hold interests through participants (sometimes called “indirect participants”). A participant is a person having an account with the depositary for the related global debt security, typically broker-dealers, banks, trust companies, clearing corporations and certain other organizations. Upon the issuance of a global debt security, the depositary will credit the participants’ accounts on its book-entry registration and transfer system with the respective principal amounts of the book-entry debt securities owned by such participants; the depositary will have no knowledge of the underlying beneficial owners of the book-entry debt securities owned by participants. Any dealers, underwriters or agents participating in the distribution of the book-entry debt securities will designate accounts to be credited. Ownership of book-entry debt securities will be shown on, and the transfer of such ownership interests will be effected only through, records maintained by the depositary for the related global debt security (with respect to interests of participants) and on the records of participants (with respect to interests of indirect participants). Some states may legally require certain purchasers to take physical delivery of such securities, which may impair your ability to own, transfer or pledge beneficial interests in book-entry debt securities.

 

So long as DTC (or its nominee) is the registered owner of a global debt security, DTC or its nominee, as the case may be, will be considered the sole owner or holder of the book-entry debt securities represented by such global debt security for all purposes under the indenture. This means that, except as described below, beneficial

---

 

owners of book-entry debt securities will not be entitled to have securities registered in their names or to receive physical delivery of a certificate in definitive form nor will such beneficial owners be considered the owners or holders of those securities under the indenture. Accordingly, to exercise any rights of a holder under the indenture each person beneficially owning book-entry debt securities must rely on DTC’s procedures for the related global debt security and, if such person is not a participant, on the procedures of the participant through which such person owns its interest. As a beneficial owner of book-entry debt securities, information regarding your holdings will come through the participant, or indirect participant, through which you own such securities.

 

Notwithstanding the above, under existing industry practice, the depositary may authorize persons on whose behalf it holds a global debt security to exercise certain of a holder’s rights. For purposes of obtaining any consents or directions required to be given by holders of the debt securities under the indenture, we, the trustee and our respective agents will treat DTC as the holder of a debt security and/or any persons specified in a written statement of the depositary with respect to that global debt security.

 

All payments of principal of, and premium and interest on, book-entry debt securities will be paid to DTC (or its nominee) as the registered holder of the related global debt security, and any redemption notices will be sent directly to DTC. Neither we, the trustee nor any other agent of ours or agent of the trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a global debt security or for maintaining, supervising or reviewing any records relating to beneficial ownership interests. We expect DTC, upon receipt of any payment of principal of, premium or interest on a global debt security, to immediately credit participants’ accounts with payments ratably according to the respective amounts of book-entry debt securities held by each participant. We also expect that payments by participants to owners of beneficial interests in book-entry debt securities held through those participants will be governed by standing customer instructions and customary practices, similar to those for securities held in “street name.”

 

We will issue certificated debt securities in exchange for each global debt security if the depositary at any time cannot or will not continue as depositary or ceases to be a clearing agency registered under the Exchange Act, and we fail to appoint a successor depositary registered as a clearing agency under the Exchange Act within 90 days. In addition, we may at any time and in our sole discretion decide not to have the book-entry debt securities represented by global debt securities; in that event, we will issue certificated debt securities in exchange for the global debt securities of that series. If an event of default with respect to the book-entry debt securities represented by those global debt securities has occurred and is continuing, holders may exchange global debt securities for certificated debt securities.



We have obtained the foregoing information concerning DTC and its book-entry system from sources we believe to be reliable, but we take no responsibility for the accuracy of this information.



Unless we state otherwise in the applicable prospectus supplement, the debt securities will not contain any provisions affording holders of the debt securities protection, such as prior consent or acceleration rights, in the event we agree to a change in control or a highly leveraged transaction (whether or not such transaction results in a change in control), which could adversely affect holders of debt securities.

 

The applicable prospectus supplement will describe any restrictive covenants applicable to any debt securities we offer for sale.

 

Unless otherwise specified in the prospectus supplement, the terms of the debt securities will provide that we may not consolidate or merge with, or sell or lease all or substantially all of our properties and assets to, any person, which we refer to as a “successor,” unless:



 



 

 

For any series of debt securities, in addition to any event of default described in the prospectus supplement applicable to that series, an event of default will include the following events,  unless otherwise specified in the prospectus supplement:

 

 

 



 

 

 

The applicable prospectus supplement will explain whether or not an event of default with respect to one series of debt securities will constitute a cross-default with respect to any other series of debt securities (except that certain events of bankruptcy, insolvency or reorganization will always constitute cross-defaults).



If an event of default with respect to any outstanding debt securities occurs and is continuing, then the trustee or the holders of 25.0% in aggregate principal amount of the outstanding debt securities of that series may, by written notice to us (and to the trustee if given by the holders), accelerate the payment of the principal (or, if the debt securities of that series are discount securities, that portion of the principal amount as may be specified in the terms of that series) of and accrued and unpaid interest, if any, on all debt securities of that series. Such acceleration is automatic (without any notice required) in the case of an event of default resulting from certain events of bankruptcy, insolvency or reorganization. Following acceleration, payments on our subordinated debt securities, if any, will be subject to the subordination provisions described below under “Subordinated Debt Securities.” At any time after acceleration with respect to debt securities of any series, but before the trustee has obtained a court judgment or decree for payment of the amounts due, the holders of a majority in principal amount of the outstanding debt securities of that series may rescind and annul the acceleration if all events of default, other than the non-payment of accelerated principal and interest, if any, with respect to debt securities of that series which have become due solely by such declaration of acceleration, have been cured or waived as provided in the indenture. The prospectus supplement relating to any series of debt securities that are discount securities will contain particular provisions relating to acceleration of a portion of the principal amount of such discount securities upon the occurrence of an event of default.

 

The indenture provides that the trustee will be under no obligation to exercise any rights or powers under the indenture at the request of any holder of outstanding debt securities unless the trustee is indemnified against any loss, liability or expense. Subject to certain rights of the trustee, the holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities of that series.

 

---

 

No holder of any debt security may institute any proceeding, judicial or otherwise, with respect to the indenture or for the appointment of a receiver or trustee, or for any remedy under the indenture, unless:

 

 

  

Notwithstanding the foregoing, the holder of any debt security will have an absolute and unconditional right to receive payment of the principal of and any interest on that debt security on or after the due dates expressed in that debt security and to institute suit for the enforcement of payment.

 

Under the indenture we must furnish the trustee a statement as to compliance with the indenture within 120 days after the end of our fiscal year. The indenture provides that, other than with respect to payment defaults, the trustee may withhold notice to the holders of debt securities of any series of a default or event of default if it in good faith determines that withholding notice is in the interests of the holders of those debt securities.

 

We may amend or supplement the indenture or a series of debt securities if the holders of at least a majority in principal amount of the outstanding debt securities of each series affected by the modifications or amendments consent thereto. We may not make any amendment or waiver without the consent of the specific holder of an affected debt security then outstanding if that amendment or waiver will:

 



 

 

 





 



Except for certain specified provisions, the holders of at least a majority in principal amount of the outstanding debt securities of any series may on behalf of all holders waive our compliance with provisions of the indenture. The holders of a majority in principal amount of the outstanding debt securities of any series may on behalf of all holders waive any past default under the indenture with respect to that series and its consequences, except a payment default or a default of a covenant or provision which cannot be modified or amended without the consent of the holder of each outstanding debt security of the series affected; provided, however, that the holders of

---

 

a majority in principal amount of the outstanding debt securities of any series may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration.

 

We may deposit with the trustee, in trust, cash or U.S. government securities in an amount that, which through the payment of interest and principal in accordance with their terms, will provide, not later than one day before the due date of any payment of money, an amount in cash, which is sufficient in the opinion of our independent public accountants to make all payments of principal and interest on, and any mandatory sinking fund payments in respect of, the debt securities of that series on the due dates for such payments in accordance with the terms of the indenture and those debt securities. If we make such a deposit, unless otherwise provided under the applicable series of debt securities, we will be discharged from any and all obligations in respect of the debt securities of such series (except for obligations relating to the transfer or exchange of debt securities and the replacement of stolen, lost or mutilated debt securities and relating to maintaining paying agencies and the treatment of funds held by paying agents and certain rights of the trustee and our obligations with respect thereto). However, this discharge may occur only if, among other things, we have delivered to the trustee a legal opinion stating that we have received from, or there has been published by, the U.S. Internal Revenue Service a ruling or, since the date of execution of the indenture, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and, based thereon confirming that, the holders of the debt securities of that series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the deposit, defeasance and discharge and will be subject to U.S. federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit, defeasance and discharge had not occurred.

 

Under the indenture (and unless otherwise provided by the terms of the applicable series of debt securities), upon making the deposit and delivering the legal opinion described in “Legal Defeasance” above, we will not need to comply with the covenants described under the heading “Consolidation, Merger and Sale of Assets” and certain other covenants set forth in the indenture, as well as any additional covenants that may be set forth in the applicable prospectus supplement, and any such noncompliance will not constitute a default or an event of default with respect to the debt securities of that series, or covenant defeasance.



If we exercise our option to effect covenant defeasance with respect to any series of debt securities and the debt securities of that series are declared due and payable because of the occurrence of any event of default, the amounts on deposit with the trustee will be sufficient to pay amounts due on the debt securities of that series at the time of their stated maturity but may not be sufficient to pay amounts due on the debt securities of that series at the time of the acceleration resulting from the event of default. We will remain liable for those payments.

 

The indentures limit the right of the trustee, should it become a creditor of us, to obtain payment of claims or secure its claims. The trustee is permitted to engage in certain other transactions. However, if the trustee acquires any conflicting interest, and there is a default under the debt securities of any series for which it is trustee, the trustee must eliminate the conflict or resign.

 

The indenture will govern the extent to which payment on any subordinated debt securities will be subordinated to the prior payment in full of all of our senior indebtedness. The subordinated debt securities also are effectively subordinated to all debt and other liabilities, including trade payables and lease obligations, if any, of our subsidiaries.

 

Upon any distribution of our assets upon any dissolution, winding up, liquidation or reorganization, the payment of principal and interest on subordinated debt securities will be subordinated to the prior payment in full of all senior indebtedness in cash or other payment satisfactory to the holders of such senior indebtedness. If

---

 

subordinated debt securities are accelerated because of an event of default, the holders of any senior indebtedness would be entitled to payment in full in cash or other payment satisfactory to such holders of all senior indebtedness obligations before the holders of the subordinated debt securities are entitled to receive any payment or distribution. The indenture requires us or the trustee to promptly notify holders of designated senior indebtedness of any acceleration of payment of the subordinated debt securities.

 

We may not make any payment on the subordinated debt securities, including upon redemption (whether at the holder’s or our option) if:

 

 



We may resume payments and distributions on the subordinated debt securities, in the case of a payment default, upon the date on which such default is cured or waived or ceases to exist; and, in the case of a non-payment default, the earlier of the date on which such nonpayment default is cured or waived and 179 days after the date on which the payment blockage notice is received, if the maturity of the designated senior indebtedness has not been accelerated, unless the indenture otherwise prohibits such payment or distribution at the time of such payment or distribution.



No new payment blockage notice may be given unless and until 365 days have elapsed since the initial effectiveness of the immediately prior payment blockage notice and all scheduled payments, premium, if any, and interest on the debt securities that have come due have been paid in full in cash. A non-payment default existing or continuing on the date of delivery of any payment blockage notice cannot be the basis for any later payment blockage notice.

 

If the trustee or any holder of the notes receives any payment or distribution of our assets in contravention of the foregoing subordination provisions, then such payment or distribution will be held in trust for the benefit of holders of senior indebtedness or their representatives to the extent necessary to make payment in full in cash or payment satisfactory to the holders of senior indebtedness of all unpaid senior indebtedness.

 

In the event of our bankruptcy, dissolution or reorganization, holders of senior indebtedness may receive more, ratably, and holders of the subordinated debt securities may receive less, ratably, than our other creditors (including our trade creditors). This subordination will not prevent the occurrence of any event of default under the indenture.

 

The indenture does not prohibit us from incurring debt, including senior indebtedness. We may from time to time incur additional debt, including senior indebtedness.

 

We are obligated to pay reasonable compensation to the trustee, reimburse the trustee for reasonable expenses and to indemnify the trustee against certain losses, liabilities or expenses it incurs in connection with its duties relating to the subordinated debt securities. The trustee’s claims for these payments will generally be senior to those of noteholders in respect of all funds collected or held by the trustee and will not be subject to subordination.

 

“Indebtedness” means:

“Senior indebtedness” means the principal, premium, if any, interest, including any interest accruing after bankruptcy, additional amounts, if any, and rent or termination payment on or other amounts due on our current or future indebtedness, whether created, incurred, assumed, guaranteed or in effect guaranteed by us, including any deferrals, renewals, extensions, refundings, amendments, modifications or supplements to the above. Senior indebtedness does not include:

 



 



Unless otherwise set forth in the prospectus supplement applicable to the particular series of debt securities, the indenture and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

The following is a description of our capital stock and the material provisions of AquaBounty’s third amended and restated certificate of incorporation, as amended (the “Certificate”) and bylaws, as amended and restated (the “Bylaws”). The following summary of the terms of the capital stock of AquaBounty is not intended to be complete and is subject in all respects to the applicable provisions of federal law governing bank holding companies, the Delaware General Corporation Law (the “DGCL”) and the Certificate and Bylaws. See the section of this Registration Statement entitled “Where You Can Find More Information” on page 1 for more information.



The authorized capital stock of AquaBounty consists of 75 million shares of common stock, par value $.001, and 5 million shares of preferred stock, par value $0.01 per share. As of January 6, 2026 3,877,695 shares of AquaBounty common stock were outstanding, and no shares of AquaBounty preferred stock were outstanding. AquaBounty preferred stock may be issued in one or more series with those terms and at those times and for any consideration as the AquaBounty Board of Directors determines.

Dividends and Liquidation Rights

.  Subject to preferences that may be applicable to any outstanding shares of our preferred stock, holders of shares of our common stock are entitled to receive ratably such dividends, if any, as our Board of Directors may declare on the common stock out of funds legally available for that purpose. Upon our liquidation, dissolution, or winding up, holders of shares of our common stock would be entitled to share ratably in all assets remaining after the payment of all debts and other liabilities and the liquidation preferences of any outstanding shares of our preferred stock.



Voting Rights

.  Holders of shares of our common stock are entitled to one vote for each share held of record on all matters submitted to a vote of shareholders. A majority of the votes cast at a meeting of the shareholders by the holders of shares entitled to vote is required for any action by the shareholders except (a) as otherwise provided by law or the Certificate and (b) that directors are to be elected by a plurality of the votes cast at elections. Holders of shares of our common stock do not have cumulative voting rights in the election of directors.

Our Certificate provides that all stockholder actions are required to be taken by a vote of the stockholders at an annual or special meeting; that stockholders may not take any action by written consent in lieu of a meeting; that only the chairman of our Board of Directors, our chief executive officer, or a majority of the authorized number of directors may call special meetings of stockholders; and that only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of stockholders. Our Bylaws limit the business that may be conducted at an annual meeting of stockholders to those matters properly brought before the meeting.



Other Rights

.  Holders of common stock have no preemptive, conversion, or subscription rights. There are no redemption or sinking fund provisions applicable to the common stock. 

Fully Paid and Nonassessable

. All of our outstanding shares of common stock are, and the shares of common stock to be issued upon conversion or exercise of our convertible securities, if applicable, will be when issued, fully paid and nonassessable.

Future Issuance of Preferred Stock

.  There are no shares of preferred stock issued or outstanding. Our Board of Directors may, without further action by our shareholders, from time to time, direct the issuance of shares of preferred stock in one or more series and may, at the time of issuance, determine the rights, preferences, and limitations of each series. These shares of preferred stock may have conversion, dividend, liquidation, or voting rights that could adversely affect the holders of shares of our common stock, and they may render more difficult or tend to discourage a merger, tender offer, or proxy contest; the assumption of control by a holder of a large block of our securities; or the removal of incumbent management.

---

 

Changes in Control

.  Certain provisions of the DGCL and of our Certificate and Bylaws could have the effect of delaying, deferring, or discouraging another party from acquiring control of us. These provisions might inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover attempts, make it more difficult to accomplish transactions that stockholders might otherwise deem to be in their best interests, and prevent changes in our Board of Directors or management.

Advance Notice Procedures

.  The Bylaws establish advance notice procedures for shareholders to make nominations of candidates for election as directors or bring other business before an annual meeting of our shareholders. If the officer presiding at a meeting determines that a person was not nominated, or other business was not brought before the meeting, in accordance with the notice procedure, that person will not be eligible for election as a director, or that business will not be conducted at the meeting.

Authorized but Unissued Shares

.  The authorized but unissued shares of our common stock are available for future issuance without shareholder approval. The existence of authorized but unissued shares of our common stock could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger, or otherwise.

Amendment to Bylaws and Certificate

.  As required by the DGCL, any amendment of Certificate must first be approved by a majority of our Board of Directors and, if required by law or our Certificate, thereafter be approved by a majority of the outstanding shares entitled to vote on the amendment, and a majority of the outstanding shares of each class entitled to vote thereon as a class, except that the amendment of the provisions relating to directors, limitation of liability, and choice of forum must be approved by not less than 66 2/3% of the outstanding shares entitled to vote on the amendment. Our Bylaws may be amended by the affirmative vote of a majority vote of the directors then in office, subject to any limitations set forth in the Bylaws, and may also be amended by the affirmative vote of at least 66 2/3% of the outstanding shares entitled to vote on the amendment.

Board Composition and Filling Vacancies

.  In accordance with our Certificate,  members of our Board of Directors may be removed without cause by the affirmative vote of the holders of 66 2/3% or more of the shares then entitled to vote at an election of directors, or with cause by the affirmative vote of a majority of the shares then entitled to vote at an election of directors. Furthermore, any vacancy on our Board of Directors, however occurring, including a vacancy resulting from an increase in the size of our Board of Directors, may only be filled by the affirmative vote of a majority of our directors then in office even if less than a quorum. Our Board of Directors is not divided into classes. 

Forum

.  Our Certificate provides that the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for (1) any derivative action or proceeding brought on our behalf; (2) any action asserting a claim of breach of a fiduciary duty owed by any director, officer, or other employee to us or to our stockholders; (3) any action asserting a claim arising pursuant to any provision of the DGCL; or (4) any action asserting a claim governed by the internal affairs doctrine.

Transfer Agent

.  The transfer agent for our common stock is Computershare Trust Company, N.A.

Listing

.  Our common stock is listed on Nasdaq under the symbol “AQB.”

No shares of AquaBounty preferred stock are currently outstanding. AquaBounty preferred stock may be issued by vote of the AquaBounty Board of Directors without shareholder approval. AquaBounty preferred stock may be issued in one or more classes and series, with such designations, voting rights (or without voting rights), redemption, conversion or sinking fund provisions, dividend rates or provisions, liquidation rights, and other preferences and limitations as the AquaBounty Board of Directors may determine in the exercise of its business judgment. AquaBounty preferred stock may be issued by the AquaBounty Board of Directors for a variety of reasons. 



Shares of AquaBounty preferred stock could be issued in public or private transactions in one or more (isolated or series of) issues. The shares of any issue of AquaBounty preferred stock could be issued with rights, including voting, dividend, and liquidation features, superior to those of any issue or class of shares, including the shares of AquaBounty common stock to be issued in connection with the merger. The issuance of

---

 

shares of AquaBounty preferred stock could serve to dilute the voting rights or ownership percentage of the holders of AquaBounty common stock. The issuance of AquaBounty preferred stock might also serve to deter or block any attempt to obtain control of AquaBounty or to facilitate any such attempt.



We will describe in a prospectus supplement relating to any series of preferred stock being offered the following terms:





Unless we specify otherwise in the applicable prospectus supplement, the preferred stock will rank, relating to dividends and upon our liquidation, dissolution or winding up:





We may issue depositary receipts representing interests in shares of particular series of preferred stock which are called depositary shares. We will deposit the preferred stock of a series which is the subject of depositary shares with a depositary, which will hold that preferred stock for the benefit of the holders of the depositary shares, in accordance with a depositary agreement between the depositary and us. The holders of depositary shares will be entitled to all the rights and preferences of the preferred stock to which the depositary shares relate, including dividend, voting, conversion, redemption and liquidation rights, to the extent of their interests in that preferred stock.



While the depositary agreement relating to a particular series of preferred stock may have provisions applicable solely to that series of preferred stock, unless otherwise stated in the applicable prospectus supplement, all depositary agreements relating to preferred stock we issue will include the following provisions:



Each time we pay a cash dividend or make any other type of cash distribution with regard to preferred stock of a series, the depositary will distribute to the holder of record of each depositary share relating to that series of preferred stock an amount equal to the dividend or other distribution per depositary share the depositary receives. If

---

 

there is a distribution of property other than cash, the depositary either will distribute the property to the holders of depositary shares in proportion to the depositary shares held by each of them, or the depositary will, if we approve, sell the property and distribute the net proceeds to the holders of the depositary shares in proportion to the depositary shares held by them.



A holder of depositary shares will be entitled to receive, upon surrender of depositary receipts representing depositary shares, the number of whole or fractional shares of the applicable series of preferred stock, and any money or other property, to which the depositary shares relate.



Whenever we redeem shares of preferred stock held by a depositary, the depositary will be required to redeem, on the same redemption date, depositary shares constituting, in total, the number of shares of preferred stock held by the depositary which we redeem, subject to the depositary’s receiving the redemption price of those shares of preferred stock. If fewer than all the depositary shares relating to a series are to be redeemed, the depositary shares to be redeemed will be selected by lot or by another method we determine to be equitable.



Any time we send a notice of meeting or other materials relating to a meeting to the holders of a series of preferred stock to which depositary shares relate, we will provide the depositary with sufficient copies of those materials so they can be sent to all holders of record of the applicable depositary shares, and the depositary will send those materials to the holders of record of the depositary shares on the record date for the meeting. The depositary will solicit voting instructions from holders of depositary shares and will vote or not vote the preferred stock to which the depositary shares relate in accordance with those instructions.



In the event of our liquidation, dissolution or winding up, the holder of each depositary share will be entitled to what the holder of the depositary share would have received if the holder had owned the number of shares (or fraction of a share) of preferred stock which is represented by the depositary share.



If shares of a series of preferred stock are convertible into common stock or other of our securities or property, holders of depositary shares relating to that series of preferred stock will, if they surrender depositary receipts representing depositary shares and appropriate instructions to convert them, receive the shares of common stock or other securities or property into which the number of shares (or fractions of shares) of preferred stock to which the depositary shares relate could at the time be converted.



We and the depositary may amend a depositary agreement, except that an amendment which materially and adversely affects the rights of holders of depositary shares, or would be materially and adversely inconsistent with the rights granted to the holders of the preferred stock to which they relate, must be approved by holders of at least two-thirds of the outstanding depositary shares. No amendment will impair the right of a holder of depositary shares to surrender the depositary receipts evidencing those depositary shares and receive the preferred stock to which they relate, except as required to comply with law. We may terminate a depositary agreement with the consent of holders of a majority of the depositary shares to which it relates. Upon termination of a depositary agreement, the depositary will make the whole or fractional shares of preferred stock to which the depositary shares issued under the depositary agreement relate available to the holders of those depositary shares. A depositary agreement will automatically terminate if:







There will be provisions: (1) requiring the depositary to forward to holders of record of depositary shares any reports or communications from us which the depositary receives with respect to the preferred stock to which the depositary shares relate; (2) regarding compensation of the depositary; (3) regarding resignation of the depositary; (4) limiting our liability and the liability of the depositary under the depositary agreement (usually to failure to act in good faith, gross negligence or willful misconduct); and (5) indemnifying the depositary against certain possible liabilities.



The preceding description and any description of depositary shares in the applicable prospectus supplement does not purport to be complete and is subject to and is qualified in its entirety by reference to the form of depositary receipt which will be filed with the SEC in connection with the offering of such depositary shares.



We may issue warrants to purchase debt or equity securities. We may issue warrants independently or together with any offered securities. The warrants may be attached to or separate from those offered securities. We will issue the warrants under warrant agreements to be entered into between us and a bank or trust company, as warrant agent, all as described in the applicable prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.



The prospectus supplement relating to any warrants that we may offer will contain the specific terms of the warrants. These terms may include the following:





























---

 

Each warrant will entitle the holder of warrants to purchase for cash the amount of debt or equity securities, at the exercise price stated or determinable in the prospectus supplement for the warrants. Warrants may be exercised at any time up to the close of business on the expiration date shown in the applicable prospectus supplement, unless otherwise specified in such prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void. Warrants may be exercised as described in the applicable prospectus supplement. When the warrant holder makes the payment and properly completes and signs the warrant certificate at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement, we will, as soon as possible, forward the debt or equity securities that the warrant holder has purchased. If the warrant holder exercises the warrant for less than all of the warrants represented by the warrant certificate, we will issue a new warrant certificate for the remaining warrants.



The preceding description and any description of warrants in the applicable prospectus supplement does not purport to be complete and is subject to and is qualified in its entirety by reference to the form of warrant which will be filed with the SEC in connection with the offering of such warrants.



We may issue purchase contracts, including contracts obligating or entitling holders to purchase from us, and obligating or entitling us to sell to holders, a specific number of shares of common stock, preferred stock, debt securities or other securities, property or assets, at a future date or dates. Alternatively, the purchase contracts may obligate or entitle us to purchase from holders, and obligate or entitle holders to sell to us, a specific or varying number of shares of preferred stock, common stock, debt securities or other securities, property or assets, at a future date. The price per share of preferred stock or common stock may be fixed at the time the purchase contracts are issued or may be determined by reference to a specific formula described in the purchase contracts. We may issue purchase contracts separately or as a part of units each consisting of a purchase contract and debt securities, undivided beneficial ownership interests in debt securities or shares of preferred stock or debt obligations of third parties, including U.S. Treasury securities, securing holders’ obligations to purchase the preferred stock, common stock, debt securities or other securities, property or assets, under the purchase contracts. The purchase contracts may require us to make periodic payments to holders or vice versa and the payments may be unsecured or prefunded on some basis. The purchase contracts may require holders to secure their obligations in a specified manner. The terms of any purchase contracts and any related guarantee will be described in the applicable prospectus supplement.



The preceding description and any description of purchase contracts in the applicable prospectus supplement does not purport to be complete and is subject to and is qualified in its entirety by reference to the form of purchase contract agreement which will be filed with the SEC in connection with the offering of such purchase contracts.



We may issue units comprised of two or more of the other securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

 

The applicable prospectus supplement may describe:

The preceding description and any description of units in the applicable prospectus supplement does not purport to be complete and is subject to and is qualified in its entirety by reference to the form of unit agreement which will be filed with the SEC in connection with the offering of such units.



We may sell the securities from time to time pursuant to underwritten public offerings, negotiated transactions, block trades or a combination of these methods. We may sell the securities to or through underwriters or dealers, through agents, or directly to one or more purchasers. We may distribute securities from time to time in one or more transactions:





​

We may also sell equity securities covered by this registration statement in an “at-the-market offering” as defined in Rule 415 under the Securities Act. Such offering may be made into an existing trading market for such securities in transactions at other than a fixed price, either:



​



​

Such “at-the-market” offerings, if any, may be conducted by underwriters acting as principal or agent.



A prospectus supplement or supplements (and any related free writing prospectus that we may authorize to be provided to you) will describe the terms of the offering of the securities, including, to the extent applicable:



​

​

​

​



​

Only underwriters named in the prospectus supplement are underwriters of the securities offered by the prospectus supplement.



If underwriters are used in the sale, they will acquire the securities for their own account and may resell the securities from time to time in one or more transactions at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the securities will be subject to

---

 

the conditions set forth in the applicable underwriting agreement. We may offer the securities to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Subject to certain conditions, the underwriters will be obligated to purchase all of the securities offered by the prospectus supplement. Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may change from time to time. We may use underwriters with whom we have a material relationship. We will describe in the prospectus supplement, naming the underwriter, the nature of any such relationship.



We may sell securities directly or through agents we designate from time to time. We will name any agent involved in the offering and sale of securities, and we will describe any commissions we will pay the agent in the prospectus supplement. Unless the prospectus supplement states otherwise, our agent will act on a best-efforts basis for the period of its appointment.



We may authorize agents or underwriters to solicit offers by certain types of institutional investors to purchase securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. We will describe the conditions to these contracts and the commissions we must pay for solicitation of these contracts in the prospectus supplement.



We may provide agents and underwriters with indemnification against civil liabilities related to this offering, including liabilities under the Securities Act, or contribution with respect to payments that the agents or underwriters may make with respect to these liabilities. Agents and underwriters may engage in transactions with, or perform services for, us in the ordinary course of business.

All securities we offer, other than common stock, will be new issues of securities with no established trading market. Any underwriters may make a market in these securities, but will not be obligated to do so and may discontinue any market making at any time without notice. We cannot guarantee the liquidity of the trading markets for any securities.



Any underwriter may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids. Overallotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve purchases of the securities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a stabilizing or covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time. These transactions may be effected on any exchange or over-the-counter market or otherwise.



Any underwriters who are qualified market makers on Nasdaq may engage in passive market making transactions in the securities on Nasdaq in accordance with Rule 103 of Regulation M, during the business day prior to the pricing of the offering, before the commencement of offers or sales of the securities. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker’s bid, however, the passive market maker’s bid must then be lowered when certain purchase limits are exceeded. Passive market making may stabilize the market price of the securities at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time.



We will identify the specific plan of distribution, including any underwriters, dealers, agents or direct purchasers and their compensation in a prospectus supplement.



Unless otherwise indicated in the applicable prospectus supplement, certain legal matters will be passed upon for us by FBT Gibbons LLP, Louisville, Kentucky.
