This prospectus relates to the resale or other disposition, from time to time, by the selling stockholders named in this prospectus (the “selling stockholders”) of up to 2,678,570 shares of our common stock, par value $0.0001 per share (“Common Stock”), consisting of (i) 1,116,070 shares of our Common Stock (the “Purchased Shares”) issued to the selling stockholders pursuant to that certain Stock Purchase and Conversion Agreement, dated as of April 2, 2026, amended by that certain Waiver and Omnibus Amendment of Note and Stock Agreements, dated as of April 13, 2026 (the “Amendment”) (the “Stock Purchase and Conversion Agreement”), and (ii) 1,562,500 shares of our Common Stock (the “Conversion Shares”) issuable upon the conversion of notes (the “Notes”) issued pursuant to that certain Note Purchase Agreement, dated as of April 2, 2026, as amended by the Amendment (the “Note Purchase Agreement”). The Purchased Shares and the Conversion Shares registered by this prospectus are collectively referred to herein as the “Shares.”

Under the Note Purchase Agreement, the selling stockholders have the right, at their election, to convert up to ten percent of the aggregate principal amount (including payment-in-kind interest capitalized thereon) of the Notes then outstanding into shares of our Common Stock at a price per share equal to $6.72, as calculated in accordance with the Note Purchase Agreement (the “Conversion Price”). Each selling stockholder’s conversion right is subject to certain beneficial ownership limitations. The actual number of shares issuable upon conversion of the Notes may differ from the amount registered hereunder, depending on, among other things, the aggregate principal amount of Notes outstanding at the time of conversion and the actual amount of payment-in-kind interest capitalized thereon (which accrues at a floating rate). To the extent the actual number of shares issuable upon conversion of the Notes exceeds the number of Conversion Shares registered hereby, we will be required to file a post-effective amendment to this registration statement or a new registration statement to register such additional shares.

We are not selling any Shares under this prospectus and will not receive any of the proceeds from the sale or other disposition of Shares by the selling stockholders. Our registration of shares of Common Stock covered by this prospectus does not mean that the selling stockholders will offer or sell any such Shares.

We are registering the offer and resale of the Shares to satisfy a covenant set forth in the Stock Purchase and Conversion Agreement in which we agreed to register the resale of the Shares within a limited period of time following the date in which our Registration Statement on Form S-3 (File No. 333-294295) became effective.

Any shares of our Common Stock subject to resale hereunder will have been issued by us and received by the selling stockholders prior to any resale of such Shares pursuant to this prospectus.

The selling stockholders, or their donees, pledgees, transferees or other successors-in-interest, may sell the Shares on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale, on the over-the-counter market, in one or more transactions otherwise than on these exchanges or systems, such as privately negotiated transactions, or using a combination of these methods, and at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. See the disclosure under the heading “Plan of Distribution” elsewhere in this prospectus for more information about how the selling stockholders may sell or otherwise dispose of their Shares hereunder.

Our Common Stock is listed on the Nasdaq Capital Market under the symbol “IRD”. On June 1, 2026, the last reported sale price of our Common Stock was $4.12.

We are a “smaller reporting company” under federal securities laws and as such, have elected to comply with reduced public company reporting requirements for this prospectus and the documents incorporated by reference herein and may elect to comply with reduced public company reporting requirements in future filings. See “Prospectus Summary—Implications of Being a Smaller Reporting Company.”

Investing in our securities involves significant risks. We strongly recommend that you read carefully the risks we describe in this prospectus and in any accompanying prospectus supplement, as well as the risk factors that are incorporated by reference into this prospectus from our filings made with the Securities and Exchange Commission. See “Risk Factors” beginning on page 5 of this prospectus.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.

This prospectus is part of a registration statement on Form S-3 that we filed with the Securities and Exchange Commission (the “SEC”), using a “shelf” registration process. The selling stockholders named in this prospectus (the “selling stockholders”) may resell, from time to time, in one or more offerings, shares of our Common Stock (as defined below) offered by this prospectus. Information about the selling stockholders may change over time. When the selling stockholders sell shares of our Common Stock under this prospectus, we will, if necessary and required by law, provide a prospectus supplement that will contain specific information about the terms of that offering. Any prospectus supplement may also add to, update, modify or replace information contained in this prospectus. If a prospectus supplement is provided and the description of the offering in the prospectus supplement varies from the information in this prospectus, you should rely on the information in the prospectus supplement. You should carefully read this prospectus and the accompanying prospectus supplement, if any, along with all of the information incorporated by reference herein and therein, before making an investment decision.

You should rely only on the information contained or incorporated by reference in this prospectus and any applicable prospectus supplement. We have not, and the selling stockholders have not, authorized any other person to provide you with different or additional information. If anyone provides you with different or additional information, you should not rely on it. This prospectus is not an offer to sell, nor are the selling stockholders seeking an offer to buy, the shares offered by this prospectus in any jurisdiction where the offer and sale is not permitted. No offers or sales of any of the shares of our Common Stock are to be made in any jurisdiction in which such an offer or sale is not permitted. You should assume that the information contained in this prospectus or any applicable prospectus supplement is accurate only as of the date on the front cover thereof or the date of the document incorporated by reference, regardless of the time of delivery of this prospectus or any applicable prospectus supplement or any sales of the shares of our Common Stock offered hereby or thereby.

You should read the entire prospectus and any prospectus supplement and any related issuer free writing prospectus, as well as the documents incorporated by reference into this prospectus or any prospectus supplement or any related issuer free writing prospectus, before making an investment decision. Neither the delivery of this prospectus, any prospectus supplement or any issuer free writing prospectus nor any sale made hereunder shall under any circumstances imply that the information contained or incorporated by reference herein or in any prospectus supplement or issuer free writing prospectus, as applicable, has not changed since the date of this prospectus or any prospectus supplement or any issuer free writing prospectus. You should assume that the information appearing in this prospectus, any prospectus supplement or any document incorporated by reference herein or therein is accurate only as of the date of the applicable documents, regardless of the time of delivery of this prospectus or any sale of securities. Our business, financial condition, results of operation and prospects may have changed since that date.

The terms “Opus Genetics,” the “Company,” “our,” “us” and “we,” as used in this prospectus, refer to Opus Genetics, Inc., unless we state otherwise or the context indicates otherwise. This prospectus contains trade names, trademarks and service marks of others, which are the property of their respective owners. Solely for convenience, trademarks and trade names referred to in this prospectus may appear without the ® or TM symbols.

Investing in our securities involves risk. You should carefully consider the specific risks discussed or incorporated by reference into this prospectus or any applicable prospectus supplement, together with all the other information contained or incorporated by reference in this prospectus or any applicable prospectus supplement. You should also consider the risks, uncertainties and assumptions discussed under the caption “Risk Factors” included in our Annual Report on Form 10-K for the year ended December 31, 2025 and in subsequent filings, which are incorporated by reference into this prospectus. These risk factors may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future or by a prospectus supplement relating to a particular offering of our securities. These risks and uncertainties are not the only risks and uncertainties we face. Additional risks and uncertainties not presently known to us, or that we currently view as immaterial, may also impair our business. If any of the risks or uncertainties described in our SEC filings or any prospectus supplement or any additional risks and uncertainties actually occur, our business, financial condition and results of operations could be materially and adversely affected. In that case, the trading price of our securities could decline and you might lose all or part of your investment.

We are registering for resale up to 2,678,570 Shares issued to the selling stockholders to fulfill our contractual obligations under the Stock Purchase and Conversion Agreement. Sales of substantial amounts of shares of our Common Stock in the public market, or the perception that such sales might occur, could adversely affect the market price of our Common Stock. We cannot predict if and when the selling stockholders may sell such Shares in the public markets. Furthermore, in the future, we may issue additional shares of Common Stock or other equity or debt securities exercisable for, or convertible into, shares of Common Stock. Any such issuances could result in substantial dilution to our existing stockholders and could cause our stock price to decline.

This prospectus contains forward-looking statements within the meaning of the safe harbor provisions of Section 27A of the Securities Act, and Section 21E of the Exchange Act. These forward-looking statements relate to us, our business prospects and our results of operations and are subject to certain risks and uncertainties posed by many factors and events that could cause our actual business, prospects and results of operations to differ materially from those anticipated by such forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, statements concerning our strategic business plans, the applications of our product candidates, ongoing discussions with the U.S. Food and Drug Administration (the “FDA”) regarding various of our drug products, and continued drug development and commercialization under our agreement with Viatris, Inc. and those described under the heading “Risk Factors” included in this prospectus. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this prospectus. In some cases, you can identify forward-looking statements by the following words: “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “ongoing,” “plan,” “potential,” “predict,” “project,” “should,” “will,” “would” or the negative of these terms or other comparable terminology, although not all forward-looking statements contain these words. We undertake no obligation to revise any forward-looking statements in order to reflect events or circumstances that might subsequently arise. Readers are urged to carefully review and consider the various disclosures made by us in this prospectus and in our other reports filed with the SEC that advise interested parties of the risks and factors that may affect our business.

These forward-looking statements reflect our management’s beliefs and views with respect to future events and are subject to risks and uncertainties, many of which are beyond our control, that could cause our actual results to differ materially from those in these forward-looking statements, including, without limitation:

We discuss many of these risks in greater detail under Part I, Item 1A, “Risk Factors”, in our Annual Report on Form 10-K for the year ended December 31, 2025 and subsequent reports filed with or furnished to the SEC. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. Given these uncertainties, you should not place undue reliance on any forward-looking statements made by us, which speak only as of the date they were made. We undertake no obligation to publicly update any forward-looking statements after the date of this prospectus supplement, whether as a result of new information, future events or otherwise, except as required by law.

You should read this prospectus, any prospectus supplement, documents we have filed with the SEC that are incorporated by reference herein and therein and any free writing prospectus that we may authorize for use in connection with this offering completely and with the understanding that our actual future results may be materially different from what we expect. We qualify all of the forward-looking statements in the foregoing documents by these cautionary statements.

We will not receive any proceeds from the sale of Shares by the selling stockholders. Any proceeds from the sale by the selling stockholders of the Common Stock offered by this prospectus will be received by the selling stockholders. See “Selling Stockholders.”

We will bear the costs, fees and expenses in effecting the registration of the Shares covered by this prospectus, including all registration and filing fees, Nasdaq listing fees and fees and expenses of our counsel and our independent registered public accounting firm.

This prospectus covers the resale or other disposition from time to time by the selling stockholders identified in the table below of up to an aggregate of 2,678,570 shares of our Common Stock. The selling stockholders may from time to time offer and sell any or all of the Shares set forth below pursuant to this prospectus and any accompanying prospectus supplement.

On April 2, 2026, we entered into the Stock Purchase and Conversion Agreement, as amended by that certain Waiver and Omnibus Amendment of Note and Stock Agreements, dated as of April 13, 2026 (the “Amendment”) (the “Stock Purchase and Conversion Agreement”), providing for the issuance and sale of an aggregate of 1,116,070 shares of our Common Stock (the “Purchased Shares”) at a purchase price of $4.48 per share. On the same date, we entered into the Note Purchase Agreement (as amended by the Amendment, the “Note Purchase Agreement”), pursuant to which we agreed to issue and sell notes (the “Notes”) in an aggregate committed principal amount of up to $105,000,000, in multiple tranches, at a purchase price equal to 100% of the principal amount thereof. Under the Note Purchase Agreement, the selling stockholders (or their designated holders) have the right, at their election, to convert up to ten percent (10%) of the aggregate principal amount (including payment-in-kind interest capitalized thereon) of the Notes then outstanding into shares of Common Stock (the “Conversion Shares”) at a price per share equal to $6.72, as calculated in accordance with the Note Purchase Agreement (the “Conversion Price”). Each selling stockholder’s conversion right is subject to certain beneficial ownership limitations. The Purchased Shares and the Conversion Shares are collectively referred to herein as the “Shares.”

The actual number of shares issuable upon conversion of the Notes may differ from the amount registered hereunder depending on, among other things, the aggregate principal amount of Notes outstanding at the time of conversion and the actual amount of payment-in-kind interest capitalized thereon (which accrues at a floating rate). To the extent the actual number of shares issuable upon conversion of the Notes exceeds the number of Conversion Shares registered hereby, we will be required to file a post-effective amendment to this registration statement or a new registration statement to register such additional shares.

This prospectus covers the resale or other disposition by the selling stockholders or their pledgees, donees, transferees or other successors-in-interest that receive their shares after the date of this prospectus of up to (i) 1,116,070 Purchased Shares and (ii) up to 1,562,500 Conversion Shares. Throughout this prospectus, when we refer to the “selling stockholders,” we are referring to the investors under the Stock Purchase and Conversion Agreement listed in the table below.

We are registering the Shares to satisfy a covenant set forth in the Stock Purchase and Conversion Agreement in which we agreed to register the resale of the Shares within a limited period of time following the date in which our Registration Statement on Form S-3 (File No. 333-294295) became effective, and to permit the selling stockholders and their pledgees, donees, transferees or other successors-in-interest that receive their shares after the date of this prospectus to resell or otherwise dispose of the shares in the manner contemplated under “Plan of Distribution” herein.

Except as otherwise disclosed herein, the selling stockholders do not have, and within the past three years have not had, any position, office or other material relationship with us.

The following table sets forth the number and percentage of shares of our Common Stock beneficially owned by the selling stockholders as of May 31, 2026, taking into account the number of Shares that may be offered under this prospectus and the number and percentage of our Common Stock beneficially owned by the selling stockholders assuming all of the Shares offered under this prospectus are sold. Beneficial ownership is determined in accordance with the rules of the SEC and includes voting or investment power with respect to shares of our Common Stock. Generally, a person “beneficially owns” shares of our Common Stock if the person has or shares with others the right to vote those shares or to dispose of them, or if the person has the right to acquire voting or disposition rights within sixty days.

The selling stockholders may sell some, all or none of their Shares. We do not know how long the selling stockholders will hold the Shares before selling them, and we currently have no agreements, arrangements or understandings with the selling stockholders regarding the sale or other disposition of any of the Shares, other than as contemplated by the Stock Purchase and Conversion Agreement. The Shares covered hereby may be offered from time to time by the selling stockholders, provided that Conversion Shares may only be offered after they have been issued upon conversion of the Notes in accordance with the terms of the Note Purchase Agreement.

The information set forth below is based upon information obtained from the selling stockholders and upon information in our possession regarding the issuance of the Purchased Shares and the Conversion Shares in connection with the Stock Purchase and Conversion Agreement and the Note Purchase Agreement. The percentages of Common

Stock owned after the offering by each selling stockholder below are based on 82,565,835 shares of Common Stock outstanding as of May 31, 2026, and assumes the conversion of the Notes. The numbers of shares of Common Stock beneficially owned before and after the offering presented in the table below do not give effect to any beneficial ownership limitations with respect to the Conversion Shares.

We are registering the Shares issued to the selling stockholders to permit the sale, transfer or other disposition of these shares by the selling stockholders or their donees, pledgees, transferees or other successors-in-interest from time to time after the date of this prospectus. We will not receive any of the proceeds from the sale by the selling stockholders of the Shares. We will, or will procure to, bear all fees and expenses incident to our obligation to register the Shares.

The selling stockholders may sell all or a portion of the Shares beneficially owned by them and offered hereby from time to time directly or through one or more underwriters, broker-dealers or agents, and in the case of the Conversion Shares, such shares may only be offered after they have been issued upon conversion of the Notes in accordance with the terms of the Note Purchase Agreement. If the Shares are sold through underwriters or broker-dealers, the selling stockholders will be responsible for underwriting discounts (it being understood that the selling stockholders shall not be deemed to be underwriters solely as a result of their participation in this offering) or commissions or agents’ commissions. The Shares may be sold on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale, in the over-the-counter market or in transactions otherwise than on these exchanges or systems or in the over-the-counter market and in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected in transactions that may involve crosses or block transactions. The selling stockholders may use any one or more of the following methods when selling Shares:

The selling stockholders also may resell all or a portion of the Shares in open market transactions in reliance upon Rule 144, as permitted by that rule, or Section 4(a)(1) under the Securities Act, if available, rather than under this prospectus, provided that they meet the criteria for, and conform to, the requirements of those provisions.

Broker-dealers engaged by the selling stockholders may arrange for other broker-dealers to participate in sales. If the selling stockholders effect such transactions by selling Shares to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from purchasers of the Shares for whom they may act as agent or to whom they may sell as principal. Such commissions will be in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction will not be in excess of a customary brokerage commission in compliance with FINRA Rule 2121, and in the case of a principal transaction, a markup or markdown in compliance with FINRA IM-2121.01.

In connection with sales of the Shares or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the Shares in the course of hedging in positions they assume. The selling stockholders may also sell Shares short and if such short sale takes place

after the date that the registration statement of which this prospectus forms a part is declared effective by the SEC, the selling stockholders may deliver Shares covered by this prospectus to close out short positions and to return borrowed Shares in connection with such short sales. The selling stockholders may also loan or pledge Shares to broker-dealers that in turn may sell such shares, to the extent permitted by applicable law. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities that require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). Notwithstanding the foregoing, the selling stockholders have been advised that they may not use Shares the resale of which has been registered on this registration statement to cover short sales of our Common Stock made prior to the date the registration statement, of which this prospectus forms a part, has been declared effective by the SEC.

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the Shares owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the Shares from time to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act, amending, if necessary, the list of selling stockholders to include the pledgee, transferee or other successor-in-interest as a selling stockholder under this prospectus. The selling stockholders also may transfer or donate the Shares in other circumstances, in which case the transferees, donees, pledgees or other successors-in-interest will be the selling beneficial owners for purposes of this prospectus.

The selling stockholders and any broker-dealer or agent participating in the distribution of the Shares may be deemed to be “underwriters” within the meaning of Section 2(11) of the Securities Act in connection with such sales. In such event, any commissions paid, or any discounts or concessions allowed to, any such broker-dealer or agent and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Selling stockholders who are “underwriters” within the meaning of Section 2(11) of the Securities Act will be subject to the applicable prospectus delivery requirements of the Securities Act, including Rule 172 thereunder and may be subject to certain statutory liabilities, including but not limited to, Sections 11, 12 and 17 of the Securities Act and Rule 10b-5 under the Exchange Act.

Each selling stockholder has informed the Company that it is not a registered broker-dealer and does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the Shares. Upon the Company being notified in writing by a selling stockholder that any material arrangement has been entered into with a broker-dealer for the sale of Common Stock through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer, a supplement to this prospectus will be filed, if required, pursuant to Rule 424(b) under the Securities Act, disclosing (i) the name of each such selling stockholder and of the participating broker-dealer(s), (ii) the number of Shares involved, (iii) the price at which such Shares were sold, (iv) the commissions paid or discounts or concessions allowed to such broker-dealer(s), where applicable, (v) that such broker-dealer(s) did not conduct any investigation to verify the information set out in this prospectus, and (vi) other facts material to the transaction.

Under the securities laws of some U.S. states, the Shares may be sold in such states only through registered or licensed brokers or dealers. In addition, in some U.S. states the Shares may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and complied with.

There can be no assurance that any selling stockholder will sell any or all of the Shares registered pursuant to the shelf registration statement, of which this prospectus forms a part.

Each selling stockholder and any other person participating in such distribution will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including, without limitation, to the extent applicable, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the Shares by the selling stockholder and any other participating person. To the extent applicable, Regulation M may also restrict the ability of any person engaged in the distribution of the Shares to engage in market-making activities with respect to the Shares. All of the foregoing may affect the marketability of the Shares and the ability of any person or entity to engage in market-making activities with respect to the Shares.

We will pay all expenses of the registration of the Shares pursuant to the Stock Purchase and Conversion Agreement, including, without limitation, SEC filing fees and expenses of compliance with state securities or “blue sky” laws; provided, however, that each selling stockholder will pay all underwriting discounts and selling commissions, if any, and any related legal expenses incurred by such selling stockholder. We will indemnify the selling stockholders against certain liabilities, including liabilities under the Securities Act, in accordance with the Stock Purchase and Conversion Agreement, or the selling stockholders will be entitled to contribution. We may be indemnified by the selling stockholders against certain civil liabilities, including liabilities under the Securities Act, to the extent such liabilities arise from any written information furnished to us by the selling stockholders specifically for use in this prospectus, in accordance with the Stock Purchase and Conversion Agreement, or we may be entitled to contribution.

The validity of the securities being offered hereby will be passed upon for us by Sidley Austin LLP, New York, New York.
