Up to            Shares of Common Stock

Pre-Funded Warrants to Purchase Up to            Shares of            Common Stock

Warrants to Purchase Up to            Shares of Common Stock

Up to            Shares of Common Stock Issuable Upon Exercise of Pre-Funded Warrants and Common Warrants

Pursuant to this prospectus, we are offering an aggregate of up to            shares of our common stock, par value $0.001 per share (the “common stock”), together with common warrants (the “common warrants”) to purchase up to an aggregate of            shares of our common stock. This offering also relates to the offering of the shares of common stock that are issuable from time to time upon exercise of the common warrants pursuant to this prospectus. Each share of our common stock is being sold together with one warrant to purchase one share of our common stock (the “common warrants”) at an assumed combined purchase price of $            per share and accompanying common warrant. Each common warrant will have an exercise price of $            per share, will be exercisable immediately upon issuance and will expire five years from the initial exercise date.

We are also offering to those purchasers, if any, whose purchase of the common stock in this offering would result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or at the election of the purchaser, 9.99%) of our outstanding common stock immediately following the consummation of this offering, the opportunity to purchase, if they so choose, pre-funded warrants in lieu of the common stock that would otherwise result in ownership in excess of 4.99% (or 9.99%, as applicable) of our outstanding common stock (the “pre-funded warrants”). The purchase price for each pre-funded warrant will equal the per share public offering price for the common stock in this offering less the $0.0001 per share exercise price of each such pre-funded warrant. Each pre-funded warrant will be exercisable upon issuance and will not expire prior to exercise. For each pre-funded warrant we sell, the number of shares of common stock we are offering will be decreased on a one-for-one basis. This prospectus also relates to the shares of common stock that are issuable from time to time upon exercise of the pre-funded warrants. This prospectus also relates to the shares of common stock that are issuable from time to time upon exercise of the pre-funded warrants and common warrants.

There is no established trading market for the pre-funded warrants and common warrants and we do not expect a market to develop. In addition, we do not intend to apply for the listing of the pre-funded warrants and common warrants on any national securities exchange or other trading market. Without an active trading market, the liquidity of the pre-funded warrants and common warrants will be limited.

This offering will terminate on              , 2026, unless we decide to terminate the offering (which we may do at any time in our discretion) prior to that date. We will have one closing for all the securities purchased in this offering. The combined public offering price per share of common stock (or pre-funded warrant) and accompanying common warrant will be fixed for the duration of this offering.

We have engaged             (the “placement agent”) to act as our placement agent in connection with this offering. The placement agent has agreed to use their reasonable best efforts to place the securities offered by this prospectus. We have agreed to pay the placement agent the placement agent fees set forth in the table below, which assumes that we sell all of the securities offered by this prospectus. The placement agent is not purchasing or selling any of the securities offered pursuant to this prospectus. The securities will be sold directly to the purchasers pursuant to the securities purchase agreement. There is no minimum number of securities or amount of proceeds required as a condition to closing in this offering. We will deliver all securities to be issued in connection with this offering upon receipt of investor funds received by us. Accordingly, neither we nor the placement agent have made any arrangements to place investor funds in an escrow account or trust account since the placement agent will not receive investor funds in connection with the sale of the securities offered hereunder. In addition, because there is no escrow trust or similar arrangement and no minimum offering amount, investors could be in a position where they have invested in our company, but we are unable to fulfill all of our contemplated objectives due to a lack of interest in this offering. See “Plan of Distribution” in this prospectus for more information.

Our common stock is listed on the NYSE American under the symbol “OPTT.” The last reported sale price of our common stock on September 4, 2026 was $0.18 per share

Investing in our common stock involves a high degree of risk. See “Risk Factors” beginning on page 4 of this prospectus and in our reports filed with the Securities and Exchange Commission which are incorporated by reference herein for a discussion of information that should be considered in connection with an investment in our common stock.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The placement agent expects to deliver the securities offered hereby to purchasers on or about , 2026.

The date of this prospectus is              , 2026.

TABLE OF CONTENTS

ABOUT THIS PROSPECTUS

You should rely only on the information contained in or incorporated by reference into this prospectus and in any written communication from us or the placement agent, including any free writing prospectus. Neither we nor the placement agent have authorized anyone to provide you with additional or different information. Neither we nor the placement agent are making an offer of these securities in any state where the offer or sale is not permitted. In making an investment decision, prospective investors must rely on their own examination of us and the terms of the offering, including the merits and risks involved. None of Ocean Power Technologies, Inc., the placement agent nor any of their respective representatives is making any representation to you regarding the legality of an investment decision in our common stock by you under applicable laws. You should not assume that the information provided by this prospectus or the documents incorporated by reference in this prospectus is accurate as of any date other than its respective date. Our business, financial condition, results of operations, and prospects may have changed since those dates.

Before you invest in our common stock, you should carefully read this prospectus and the documents incorporated by reference herein. The incorporated documents are described in this prospectus under the headings “Incorporation by Reference.”

This prospectus contains forward-looking statements that are subject to a number of risks and uncertainties, many of which are beyond our control. Please read “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements.”

Certain industry and market data presented in this prospectus has been derived from data included in various industry publications, surveys and forecasts. We have assumed the correctness and truthfulness of such data, including projections and estimates, when we use them in this prospectus.

RISK FACTORS

Investing in our common stock involves substantial risk. You should carefully consider the risk factors disclosed below as well as those contained in our most recent Annual Report on Form 10-K, which is incorporated by reference herein, as updated by our subsequent filings under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the other information contained in this prospectus before acquiring any of our common stock. These risks could have a material adverse effect on our business, results of operations or financial condition and cause the value of our common stock to decline. You could lose all or part of your investment.

This prospectus also contains or incorporates by reference forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of certain factors, including the risks faced by us described or incorporated by reference in this prospectus. See “Cautionary Note Regarding Forward-Looking Statements.”

Risks Related to our Common Stock and this Offering

Historically, our stock price has been volatile, and this is likely to continue; purchasers of our securities could incur substantial losses as a result.

Historically, the market price of our common stock has fluctuated significantly, and we expect that this will continue. Purchasers of our securities could incur substantial losses relating to their investment in our stock as a result. The stock market in general has recently experienced volatility that has often been unrelated or disproportionate to the operating performance of particular companies. These broad market fluctuations could result in fluctuations in the price of our common stock, which could cause purchasers of our securities to incur substantial losses. The market price for our common stock may be influenced by many factors, including:

This is a “best efforts” offering. No minimum amount of securities is required to be sold, and we may not raise the amount of capital we believe is required for our business plans, including our near-term business plans.

The placement agent has agreed to use their 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. Because there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, placement agent fees and proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth on the cover page of this prospectus. We may sell fewer than all of the securities offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this offering will not receive a refund in the event that we do not sell an amount of securities sufficient to support our continued operations, including our near-term continued operations.

The market valuation of our business may fluctuate due to factors beyond our control and the value of the investment of our stockholders may fluctuate correspondingly.

The market valuation of energy companies, such as us, frequently fluctuate due to factors unrelated to the past or present operating performance of such companies. Our market valuation may fluctuate significantly in response to a number of factors, many of which are beyond our control, including:

As a result, the value of your investment may fluctuate.

Our management will have broad discretion over the use of proceeds from this offering and may not use the proceeds effectively.

Our management will have broad discretion as to the application of the net proceeds from this offering and could spend the proceeds in a variety of ways that may ultimately fail to improve our operating results or enhance the value of our common stock. Our failure to apply these funds effectively could have a negative effect on our business and cause the price of our common stock to decline.

A large number of securities may be sold in the market following this offering, which may depress the market price of our common stock.

All of our shares of common stock sold in this offering, or issuable upon exercise of the warrants sold in this offering, will be freely tradable without restriction or further registration under the Securities Act of 1933, as amended (the “Securities Act”). As a result, a substantial number of our shares of common stock may be sold in the public market following this offering, which may cause the market price of our common stock to decline. If there are more shares of common stock offered for sale than buyers are willing to purchase, then the market price of our common stock may decline to a market price at which buyers are willing to purchase the offered shares of common stock and sellers remain willing to sell the shares of common stock.

You will experience immediate dilution in the net tangible book value per share of the common stock you purchase.

The public offering price per share of our common stock being offered is substantially higher than the net tangible book value per share of our outstanding common stock, and accordingly investors in this offering will experience immediate and substantial dilution. Based on an assumed public offering price of $         per share of our common stock and accompanying common warrant, if you purchase securities in this offering you will experience immediate dilution of approximately $          per share, representing the difference between our as adjusted net tangible book value per share after giving effect to this offering as of April 30, 2026 and the assumed public offering price of $          per share and accompanying common warrant.

The warrants are speculative in nature.

The warrants offered hereby do not confer any rights of common stock ownership on their holders, such as voting rights or the right to receive dividends, but rather merely represent the right to acquire shares of common stock at a fixed price. Specifically, commencing on the date of issuance, holders of the warrants may exercise their right to acquire the common stock and pay an exercise price of $            . There can be no assurance that the market price of the common stock will ever equal or exceed the exercise price of the warrants, and consequently, whether it will ever be profitable for holders of the warrants to exercise the warrants.

Holders of our warrants will have no rights as a common stockholder until they acquire our common stock.

Until you acquire shares of our common stock upon exercise of your warrants, you will have no rights with respect to shares of our common stock issuable upon exercise of your warrant. Upon exercise of your warrant, you will be entitled to exercise the rights of a common stockholder as to the security exercised only as to matters for which the record date occurs after the exercise date.

There is no established market for the warrants to purchase shares of our common stock being offered in this offering.

There is no established trading market for the warrants and we do not expect a market to develop. In addition, we do not intend to apply for the listing of the warrants on any national securities exchange or other trading market. Without an active trading market, the liquidity of the warrants will be limited.

The exercise price of the warrants offered by this prospectus will not be adjusted for dilutive events.

The exercise price of the warrants offered by this prospectus is subject to adjustment for certain events, such as stock splits. However, the exercise prices will not be adjusted for dilutive issuances of securities including capital stock, options, and convertible securities, which may adversely affect the market price of our common stock or the market value of such warrants without resulting in an adjustment of the exercise prices of such warrants.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

The information discussed in this prospectus, our filings with the SEC and our public releases include “forward-looking statements” within the meaning of Section 27A of the Securities Act, and Section 21E of the Exchange Act, the Private Securities Litigation Reform Act of 1995 (the “PSLRA”), or in releases made by the SEC. Such forward-looking statements involve known and unknown risks, uncertainties and other important factors that could cause the actual results, performance or achievements of us and our subsidiaries to differ materially from any future results, performance or achievements expressed or implied by such forward-looking statements. Statements that are not historical fact are forward-looking statements. Forward-looking statements can be identified by, among other things, the use of forward-looking language, such as the words “plan,” “believe,” “expect,” “anticipate,” “intend,” “estimate,” “project,” “may,” “will,” “would,” “could,” “should,” “seeks,” or “scheduled to,” or other similar words, or the negative of these terms or other variations of these terms or comparable language, or by discussion of strategy or intentions. These cautionary statements are being made pursuant to the Securities Act, the Exchange Act and the PSLRA with the intention of obtaining the benefits of the “safe harbor” provisions of such laws.

The forward-looking statements contained in or incorporated by reference into this 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, including:

Many of these factors are beyond our ability to control or predict. These factors are not intended to represent a complete list of the general or specific factors that may affect us.

In addition, management’s assumptions about future events may prove to be inaccurate. All readers are cautioned that the forward-looking statements contained in this prospectus in the documents incorporated by reference into this prospectus are not guarantees of future performance, and we cannot assure any reader that such statements will be realized or that 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 factors described in “Risk Factors” included elsewhere in this prospectus and in the documents that we include in or incorporate by reference into this prospectus, including our Annual Report on Form 10-K for the fiscal year ended April 30, 2026, and our subsequent SEC filings. All forward-looking statements speak only as of the date they are made. We do not intend to update or revise any forward-looking statements as a result of new information, future events or otherwise, except as required by law. These cautionary statements qualify all forward-looking statements attributable to us or persons acting on our behalf.

USE OF PROCEEDS

The estimated net proceeds to be received by us from this offering are expected to be approximately $          million, after deducting fees and estimated offering expenses, assuming no sale of pre-funded warrants and no exercise of the common warrants. We will only receive additional proceeds of $          from the exercise of the common warrants issuable in connection with this offering if such common warrants are exercised for cash at their exercise price of $           and the holders of such common warrants do not utilize the cashless exercise provision of the common warrants.

However, because this is a best efforts offering and there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, the placement agent’s fees and net proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth on the cover page of this prospectus.

We intend to use the net proceeds from this offering for working capital and general corporate purposes. The Series C-1 Senior Convertible Notes issued April 1, 2026 include a requirement, at the option of the holders of such notes, to use up to 30% of the net proceeds of any capital raise transaction, including this offering, to pay down amounts outstanding under such notes. These notes bear interest at an interest rate of 4.5% per annum and mature on October 1, 2027. We cannot predict whether the holders will require this repayment.

The amounts and timing of these expenditures will depend on a number of factors, such as the timing, scope, progress and results of our research and development efforts, the timing and progress of any partnering efforts, and the regulatory and competitive environment. As of the date of this prospectus, we have not determined the amount of net proceeds to be used specifically for any particular purpose or the timing of any expenditures. Accordingly, management will retain broad discretion and flexibility in applying the net proceeds from the sale of the securities, if any. Pending any use of the net proceeds from this offering, if any, we intend to deposit the proceeds in checking or money market accounts, or invest in short term highly rated investments, at financial institutions.

CAPITALIZATION

The following table sets forth our cash and cash equivalents and capitalization as of April 30, 2026 on:

DILUTION

If you invest in our securities, you will experience dilution to the extent of the difference between the public offering price you pay in this offering and the net tangible book value per share of our common stock immediately after this offering. Our net tangible book value as of April 30, 2026 was approximately $0.6 million. Net tangible book value per share is determined by dividing our total tangible assets, less total liabilities, by the number of outstanding shares of our common stock.

Our pro forma net tangible book value as of April 30, 2026 was approximately $11.3 million or $0.04 per share. Pro forma net tangible book value represents net tangible book value adjusted to take into account the following events, subsequent to April 30, 2026: (i) the issuance of 5,963,890 shares of our common stock in our “at-the-market” offering and our receipt of approximately $1.4 million in net proceeds in connection therewith, (ii) the issuance of 25,000,000 shares of our common stock and warrants exercisable for 25,000,000 shares of our common stock in a registered direct offering in June 2026, and (iii) the issuance of 10,984,848 shares of our common stock in connection with the acquisition of Columbia Power Technologies, Inc. in July 2026.

After giving effect to the pro forma adjustments described in the preceding sentence and the sale of         shares of common stock by us at an assumed combined public offering price of $         per share of common stock and accompanying common warrant and after deducting our estimated offering expenses payable by us (assuming no sale of pre-funded warrants and excluding any cash to be received upon exercise of the common warrants), our pro forma as-adjusted net tangible book value as of April 30, 2026 would have been approximately $         million, or approximately $ per share. This represents an immediate increase in net tangible book value of approximately $         per share to our existing stockholders and an immediate dilution in as adjusted net tangible book value of approximately $         per share to new investors purchasing securities in this offering. Dilution per share to new investors is determined by subtracting the pro forma as adjusted net tangible book value per share of common stock after this offering from the combined public offering price per share of common stock and accompanying common warrant paid by new investors in this offering. The following table illustrates this calculation on a per share basis:

A $             increase in the assumed combined public offering price to $         per share and accompanying common warrant, would increase our as adjusted net tangible book value as of April 30, 2026, after giving effect to this offering, by approximately $         and the dilution to our as adjusted net tangible book value per share to new investors in this offering by $         per share, assuming the number of shares of common stock and accompanying common warrant offered by us, as set forth on the cover of this prospectus, remains the same, and after deducting the placement agent fees and estimated offering expenses payable by us, assuming no exercise of the common warrants and no sale of pre-funded warrants.

The table and discussion above are based on 228,460,085 shares of our common stock outstanding as of April 30, 2026 and excludes outstanding (i) options representing the right to purchase a total of 396,179 shares of common stock at a weighted average exercise price of approximately $1.83 per share as of April 30, 2026, and (ii) unvested restricted and performance stock units representing the right to acquire a total of 23,962,673 shares of common stock as of April 30, 2026. To the extent that the outstanding stock options may be exercised or other shares issued, investors purchasing our common stock in this offering will experience further dilution. In the event we need to raise additional capital in the future and we issue additional equity securities, our then existing stockholders may also experience dilution.

DIVIDEND POLICY

We have never declared or paid any cash dividends on our common stock, and we do not currently anticipate declaring or paying cash dividends on our common stock in the foreseeable future. We currently intend to retain all of our future earnings, if any, to finance the growth and development of our business. Any future determination relating to our dividend policy will be made at the discretion of our Board and will depend on a number of factors, including future earnings, capital requirements, financial conditions, future prospects, contractual restrictions and covenants and other factors that our Board may deem relevant.

DESCRIPTION OF COMMON STOCK

Common Stock

Authorized and Outstanding Capital Stock

The following description of our common stock and provisions of our certificate of incorporation, as amended (the “certificate of incorporation”) and amended and restated bylaws (the “bylaws”) are summaries and are qualified by reference to our certificate of incorporation and bylaws, which have been incorporated by reference as exhibits to the registration statement of which this prospectus supplement forms a part.

Our authorized capital stock consists of 400,000,000 shares of common stock, par value $0.001 per share, and 5,000,000 shares of preferred stock, par value $0.001 per share, 700,000 of which are designated as Series A Participating Preferred Stock which may be issued upon the exercise of the preferred stock purchase rights described below under “Amended and Restated Section 382 Tax Benefits Preservation Plan”. On July 11, 2023, we issued preferred stock purchase rights which are attached to our common stock in connection with our adoption of a Section 382 Tax Benefits Preservation Plan, which was amended and restated on June 29, 2026 as described below under “-Amended and Restated Section 382 Tax Benefits Preservation Plan”.

As of September 1, 2026, there were 270,138,823 shares of common stock outstanding, and no shares of preferred stock were issued or outstanding. This excludes, as of September 1, 2026, outstanding (i) options representing the right to purchase a total of 388,715 shares of common stock at a weighted average exercise price of approximately $1.76 per share, (ii) unvested restricted and performance stock units representing the right to acquire a total of 21,571,787 shares of common stock, and (iii) 25,000,000 shares of common stock issuable upon exercise of certain outstanding warrants.

Description of Common Stock

Voting. Holders of common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders and do not have cumulative voting rights. Accordingly, holders of a majority of the shares of common stock entitled to vote in any election of directors may elect all of the directors standing for election.

Dividends. Holders of common stock are entitled to receive proportionately any dividends that may be declared by our board of directors (“Board”), subject to any preferential dividend rights of outstanding preferred stock.

Liquidation and Distribution. Upon our liquidation, dissolution or winding up, the holders of common stock are entitled to receive proportionately our net assets available after the payment of all debts and other liabilities and subject to the prior rights of any outstanding preferred stock. Holders of common stock have no preemptive, subscription, redemption or conversion rights. Our outstanding shares of common stock are, and the shares offered by us in this offering will be, when issued and paid for, fully paid and nonassessable. The rights, preferences and privileges of holders of common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future.

Anti-Takeover Effects of Delaware Law, Our Certificate of Incorporation and Our Bylaws

Delaware law, our certificate of incorporation, including the terms of the Series A Participating Preferred Stock, and our bylaws contain provisions that could have the effect of delaying, deferring or discouraging another party from acquiring control of us. These provisions, which are summarized below, are intended to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our Board.

Removal of Directors

Our certificate of incorporation currently provides that directors may be removed only for cause and only by the affirmative vote of the holders of 75% of our shares of capital stock entitled to vote. However, our Board approved an amendment to our bylaws that became effective on June 17, 2016, which permits our directors to be removed either for cause or without cause by our stockholders. At our annual meeting of stockholders for the year ended April 30, 2016 that was held on October 21, 2016 (the “2016 Annual Meeting”), we submitted a proposal to stockholders seeking stockholder approval to amend our certificate of incorporation to delete the reference to “for cause” in Section 6 of Article Ninth of the certificate of incorporation. This proposal to amend the certificate of incorporation did not receive the required affirmative vote of the holders of at least 75% of the outstanding shares of common stock entitled to vote at the meeting, so the proposal did not pass. However, we also submitted a proposal to stockholders at the 2016 Annual Meeting seeking approval to amend our certificate of incorporation to add a clause that specified that, to the fullest extent permitted by law, any provision in the Certificate of Incorporation that is contrary to a requirement of the Delaware General Corporate Law (the “DGCL”) shall be read in conformity with the applicable requirement of the DGCL. This second proposal only required the affirmative vote of the holders of a majority of the outstanding shares of common stock entitled to vote at the 2016 Annual Meeting, and it passed.

Our Board takes the position that under current Delaware law, the “only for cause” provision in the certificate of incorporation regarding removal of the company’s directors is not enforceable and is therefore not in conformity with the applicable requirement of the DGCL. Accordingly, we will comply with the provisions of our bylaws, as amended and as described above, relating to director removal and will not seek to enforce that provision of our certificate of incorporation relating to stockholder removal of directors only for cause, as presently in effect. Under our certificate of incorporation and bylaws, any vacancy on our Board, including a vacancy resulting from an enlargement of our Board, may be filled only by vote of a majority of our directors then in office.

The limitations on the ability of our stockholders to remove directors and fill vacancies could make it more difficult for a third party to acquire, or discourage a third party from seeking to acquire, control of us.

Stockholder Action by Written Consent; Special Meetings

Our certificate of incorporation provides that any action required or permitted to be taken by our stockholders must be effected at a duly called annual or special meeting of such holders and may not be effected by any consent in writing by such holders. Our certificate of incorporation and our bylaws also provide that, except as otherwise required by law, special meetings of our stockholders can only be called by our chairman of our Board, our chief executive officer, our president or our Board.

Advance Notice Requirements for Stockholder Proposals

Our bylaws establish an advance notice procedure for stockholder proposals to be brought before an annual meeting of stockholders, including proposed nominations of persons for election to the Board. Stockholders at an annual meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of the Board of Directors or by a stockholder of record on the record date for the meeting, that is entitled to vote at the meeting and that has delivered to our secretary a timely written notice in proper form of the stockholder’s intention to bring such business before the meeting, as well as having met certain other requirements specified in the bylaws. These provisions could have the effect of delaying until the next stockholder meeting stockholder actions that are favored by the holders of a majority of our outstanding voting securities.

Delaware Business Combination Statute

We are subject to Section 203 of the Delaware General Corporation Law. Subject to certain exceptions, Section 203 prevents a publicly held Delaware corporation from engaging in a “business combination” with any “interested stockholder” for three years following the date that the person became an interested stockholder, unless the interested stockholder attained such status with the approval of our Board or unless the business combination is approved in a prescribed manner. A “business combination” includes, among other things, a merger or consolidation involving us and the “interested stockholder” and the sale of more than 10% of our assets. In general, an “interested stockholder” is any entity or person beneficially owning 15% or more of our outstanding voting stock and any entity or person affiliated with or controlling or controlled by such entity or person.

Amended and Restated Section 382 Tax Benefits Preservation Plan

Our Board has approved the adoption of a tax benefits preservation plan in the form of a Section 382 Rights Agreement designed to protect and preserve our tax assets primarily associated with net operating loss carryforwards (“NOLs”) that could potentially be utilized in certain circumstances to offset our future taxable income and reduce its federal income tax liability. The tax benefits preservation plan was amended and restated on June 29, 2026 to among other things extend the life of the plan through June 29, 2029.

Section 382 of the Internal Revenue Code imposes limitations on the future use of a company’s NOLs if it undergoes an “ownership change.” Our ability to benefit from its tax assets would be substantially limited by Section 382 if an “ownership change” occurred. A company experiences an “ownership change” for tax purposes if the percentage of stock owned by one or a group of its 5% stockholders (as defined for tax purposes) increases by more than 50 percentage points over a rolling three-year period over the lowest percentage of stock of such corporation owned by such stockholders at any time during that period.

Our tax benefits preservation plan is similar to those adopted by numerous other public companies with significant NOLs. In order to protect our NOLs from being limited or permanently lost under Section 382, the tax benefits preservation plan is intended to reduce the likelihood of an unintended “ownership change” occurring through the buying and selling of our common stock. This is accomplished by deterring any person or group from acquiring beneficial ownership of 4.99% or more of our outstanding common stock without the approval of the Board. Our tax benefits preservation plan does not, however, block anyone from buying or selling OPT’s common stock. Accordingly, there can be no assurance that the tax benefits preservation plan will prevent an “ownership change.”

Under the terms of the tax benefits preservation plan, we distributed to our stockholders one preferred stock purchase right for each share of our common stock held as of the close of business on July 11, 2023. Any shares of common stock issued after the July 11, 2023 record date will be issued together with associated preferred stock purchase rights.

Under the tax benefits preservation plan, the rights will initially trade with our common stock. The rights will generally become exercisable only if a person (or any persons acting as a group) acquires beneficial ownership of 4.99% or more of our outstanding common stock, without the approval of the Board, after the first public announcement by us of the adoption of the tax benefits preservation plan. A person or group who acquires, without the approval of our Board, beneficial ownership of 4.99% or more of our outstanding common stock could be subject to significant dilution. If the preferred stock purchase rights become exercisable, all holders of rights, other than the person or group triggering the rights, will be entitled to purchase our common stock at a 50% discount. The Board also has the option to cause the exchange of one share of common stock for each preferred stock purchase right held. Preferred stock purchase rights held by the person or group triggering the rights will become null and void and will not be exercisable or transferable.

Stockholders who beneficially owned 4.99% or more of our outstanding common stock prior to the first public announcement by us of the adoption of the tax benefits preservation plan will not trigger any penalties under the tax benefits preservation plan so long as they do not acquire beneficial ownership of any additional shares of common stock (other than pursuant to a stock split, stock dividend, reclassification, or similar transaction effected by us) at a time when they still beneficially own 4.99% or more of such common stock. The Board also has the discretion to exempt any acquisition of our common stock from the provisions of the tax benefits preservation plan.

As amended and restated, the preferred stock purchase rights and the tax benefits preservation plan will expire no later than June 29, 2029. The preferred stock purchase rights and the tax benefits preservation plan may also expire on an earlier date upon the occurrence of other events, including a determination by our Board that (i) the tax benefits preservation plan is no longer necessary for the preservation of our tax attributes, (ii) no tax attributes may be carried forward (with such expiration occurring as of the beginning of the applicable taxable year), or (iii) prior to the time any person or group acquires 4.99% or more of our common stock, that the tax benefits preservation plan and the preferred stock purchase rights are no longer in the best interests of us and our stockholders. The preferred stock purchase rights may also be redeemed, exchanged, or terminated prior to their expiration.

Amendment of Certificate of Incorporation and Bylaws

The Delaware General Corporation Law provides generally that the affirmative vote of a majority of the shares entitled to vote on any matter is required to amend a corporation’s certificate of incorporation or bylaws, unless a corporation’s certificate of incorporation or bylaws, as the case may be, requires a greater percentage. Our bylaws may be amended or repealed by a majority vote of our Board or the affirmative vote of the holders of at least 75% of the voting power of our capital stock issued and outstanding and entitled to vote on the matter.

Limitation of Liability and Indemnification of Officers and Directors

Our certificate of incorporation limits the personal liability of directors for breach of fiduciary duty to the maximum extent permitted by the Delaware General Corporation Law. Our certificate of incorporation provides that no director will have personal liability to us or to our stockholders for monetary damages for breach of fiduciary duty or other duty as a director. However, these provisions do not eliminate or limit the liability of any of our directors:

Any amendment to or repeal of these provisions will not eliminate or reduce the effect of these provisions in respect of any act or failure to act, or any cause of action, suit or claim that would accrue or arise prior to any amendment or repeal or adoption of an inconsistent provision. If the Delaware General Corporation Law is amended to provide for further limitations on the personal liability of directors of corporations, then the personal liability of our directors will be further limited to the greatest extent permitted by the Delaware General Corporation Law.

In addition, our certificate of incorporation provides that we must indemnify our directors and officers and we must advance expenses, including attorneys’ fees, to our directors and officers in connection with legal proceedings, subject to limited exceptions.

Notice of Share Ownership

Our bylaws contain a provision requiring any beneficial owner of three percent or more of our outstanding common stock to notify us of his or her stockholdings, as well as of any change in his or her beneficial ownership of one percent or more of our outstanding common stock. Our bylaws do not provide for any specific remedy in the event a stockholder does not comply with this provision. We do not intend to make any such information public, unless required by law or the rules of the SEC or the NYSE American.

Authorized but Unissued Shares

Our authorized but unissued shares of common stock and preferred stock are available for future issuance without stockholder approval, subject to any limitations imposed by the listing standards of the NYSE American. These additional shares may be used for a variety of corporate finance transactions, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred stock could make it more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Computershare Trust Company, N.A. Its address is 250 Royall Street, Canton, MA 02021-1011, and its telephone number is 1-800-662-7232.

We are also registering the shares of our common stock issuable from time to time upon exercise of the pre-funded warrants and common warrants offered hereby.

Common Stock

The material terms and provisions of our common stock and each other class of our securities which qualifies or limits our common stock are described under the caption “Description of Common Stock” above.

Pre-Funded Warrants

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. Prospective investors should carefully review the terms and provisions of the form of the pre-funded warrants for a complete description of the terms and conditions.

Duration and Exercise Price

The pre-funded warrants offered hereby will entitle the holders thereof to purchase up to an aggregate of shares of common stock at an initial exercise price of $0.0001 per share of common stock.

The pre-funded warrants will be exercisable immediately upon issuance and will expire when exercised in full.

The pre-funded warrants will be issued in certificated form. The exercise price is subject to appropriate adjustment upon certain subdivisions or combinations of the common stock or a common stock distribution or dividend payable in shares of common stock.

Exercisability

The pre-funded warrants will be exercisable immediately upon issuance and will expire when exercised in full. The pre-funded warrants will be 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). No fractional shares of common stock will be issued in connection with the exercise of a pre-funded warrant. In lieu of fractional shares, at our option, we will pay the holder an amount in cash equal to the fractional amount multiplied by the exercise price or round up to the next whole share.

Exercise Limitation

A holder may not exercise any portion of the pre-funded warrants to the extent that the holder, together with its affiliates and any other person or entity acting as a group, would own more than 4.99% (or 9.99% if initially requested by a holder) of the outstanding shares of common stock after exercise, except that upon at least 61 days’ prior notice from the holder to us, the holder may increase the amount of ownership of outstanding shares after exercising the holder’s pre-funded warrants to up to 9.99% of the number of our shares of common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the pre-funded warrants.

Cashless Exercise

In lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of common shares determined according to a formula set forth in the pre-funded warrants.

Transferability

Subject to applicable laws and the restriction on transfer set forth in the pre-funded warrants, the pre-funded warrants may be transferred at the option of the holder upon surrender of the pre-funded warrants to us together with the appropriate instruments of transfer.

Exchange Listing

There is no established public trading market for the pre-funded warrants, and we do not expect a market to develop. We do not intend to apply to list the pre-funded warrants on any securities exchange. Without an active market, the liquidity of the pre-funded warrants will be limited. In addition, in the event the price of our common stock does not exceed the per share exercise price of the pre-funded warrants during the period when the pre-funded warrants are exercisable, the pre-funded warrants will not have any value.

Pro Rata Distributions

If, at any time while the pre-funded warrants are outstanding, we declare or make any dividend of our assets (or right to acquire our assets) to the holders of shares of Common Stock, by way of return of capital or otherwise (a “Distribution”), then holders of the pre-funded warrants shall be entitled to participate in such Distribution to the same extent that the holder of the pre-funded warrants would have participated had such holder held the number of shares of Common Stock acquirable upon complete exercise of the pre-funded warrants (without regard to the beneficial ownership limitation unless such distribution would cause the holder to exceed such limitation).

Fundamental Transactions

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, the acquisition of more than 50% of our outstanding common stock, or any person or group becoming the beneficial owner of more than 50% of the voting power represented by 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, cash or other property that the holders would have received had they exercised the pre-funded warrants immediately prior to such fundamental transaction without regard to any limitations on exercise contained in the pre-funded warrants. In the event of a fundamental transaction, we are required to cause any successor entity to assume all of our obligations under the pre-funded warrants.

Right as a Stockholder

The holder of a pre-funded warrant does not generally have the rights or privileges of a holder of our common stock, including any voting rights, until it exercises his, her or its pre-funded warrants.

Cashless Exercise

If, at the time a holder exercises its common warrants there is no effective registration statement registering, or the prospectus contained therein is not available for an issuance of the shares underlying the common warrants to the holder, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of common shares determined according to a formula set forth in the common warrants.

* To be filed by amendment.

Section 102 of the General Corporation Law of the State of Delaware permits a corporation to eliminate the personal liability of directors of a corporation to the corporation or its stockholders for monetary damages for a breach of fiduciary duty as a director, except where the director breached his duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit. The Registrant’s certificate of incorporation provides that no director of the Registrant shall be personally liable to it or its stockholders for monetary damages for any breach of fiduciary duty as director, notwithstanding any provision of law imposing such liability, except to the extent that the General Corporation Law of the State of Delaware prohibits the elimination or limitation of liability of directors for breaches of fiduciary duty.

Section 145 of the General Corporation Law of the State of Delaware provides that a corporation has the power to indemnify a director, officer, employee, or agent of the corporation and certain other persons serving at the request of the corporation in related capacities against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlements actually and reasonably incurred by the person in connection with an action, suit or proceeding to which he is or is threatened to be made a party by reason of such position, if such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful, except that, in the case of actions brought by or in the right of the corporation, no indemnification shall be made with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or other adjudicating court determines that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

The Registrant’s certificate of incorporation provides that the Registrant will indemnify each person who was or is a party or threatened to be made a party to any threatened, pending or completed action, suit or proceeding (other than an action by or in the right of the Registrant) by reason of the fact that he or she is or was, or has agreed to become, a director or officer of the Registrant, or is or was serving, or has agreed to serve, at the Registrant’s request as a director, officer, partner, employee or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise (all such persons being referred to as an “Indemnitee”), or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with such action, suit or proceeding and any appeal therefrom, if such Indemnitee acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the Registrant’s best interests, and, with respect to any criminal action or proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful. The Registrant’s certificate of incorporation provides that the Registrant will indemnify any Indemnitee who was or is a party to an action or suit by or in the right of the Registrant to procure a judgment in the Registrant’s favor by reason of the fact that the Indemnitee is or was, or has agreed to become, a director or officer of the Registrant, or is or was serving, or has agreed to serve, at the Registrant’s request as a director, officer, partner, employee or trustee or, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise, or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees) and, to the extent permitted by law, amounts paid in settlement actually and reasonably incurred in connection with such action, suit or proceeding, and any appeal therefrom, if the Indemnitee acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the Registrant, except that no indemnification shall be made with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the Registrant, unless a court determines that, despite such adjudication but in view of all of the circumstances, he or she is entitled to indemnification of such expenses. Notwithstanding the foregoing, to the extent that any Indemnitee has been successful, on the merits or otherwise, he or she will be indemnified by the Registrant against all expenses (including attorneys’ fees) actually and reasonably incurred in connection therewith. Expenses must be advanced to an Indemnitee under certain circumstances.

The Registrant maintains a general liability insurance policy that covers certain liabilities of the Registrant’s directors and officers arising out of claims based on acts or omissions in their capacities as directors or officers.

The Registrant’s directors and officers are covered by insurance policies indemnifying them against certain liabilities, including certain liabilities arising under the Securities Act of 1933, as amended, which might be incurred by them in such capacities and against which they cannot be indemnified by the Registrant.
