CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains “forward-looking statements”. Forward-looking statements discuss matters that are not historical facts.

Forward-looking statements speak only as of the date they are made, are based on various underlying assumptions and current expectations about the future and are not guarantees of future performance. Such statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, level of activity, performance or achievement to be materially different from the results of operations or plans expressed or implied by such forward-looking statements. You are cautioned to not place undue reliance on these forward-looking statements, which speak only as of their dates.

We cannot predict all the risks and uncertainties that may impact our business, financial condition, or results of operations. Accordingly, the forward-looking statements in this prospectus should not be regarded as representations that the results or conditions described in such statements will occur or that our objectives and plans will be achieved. These forward-looking statements are found at various places throughout this prospectus and include information concerning possible or projected future results of our operations, including statements about potential acquisition or merger targets, strategies or plans; business strategies; prospects; future cash flows; financing plans; plans and objectives of management; any other statements regarding future cash needs, future operations, business plans and future financial results; and any other statements that are not historical facts. We qualify all of the forward-looking statements in this prospectus by this cautionary note.

These forward-looking statements represent our intentions, plans, expectations, assumptions and beliefs about future events and are subject to a variety of factors and risks, including, but not limited to, those set forth under “Risk Factors” starting page 2 of this prospectus.

Many of those risk factors are outside of our control and could cause actual results to differ materially from the results expressed or implied by those forward-looking statements. Considering these risks, uncertainties and assumptions, the events described in the forward-looking statements might not occur or might occur to a different extent or at a different time than we have described. All subsequent written and oral forward-looking statements concerning other matters addressed in this prospectus and attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this prospectus.

Except to the extent required by law, we undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events, a change in events, conditions, circumstances or assumptions underlying such statements, or otherwise.

THE COMPANY

Overview

Neuraxis, Inc. (“we”, “us”, the “Company” or “Neuraxis”) is a first-to-market growth-stage medical technology company focused on neuromodulation therapies for chronic and debilitating conditions in gastrointestinal (GI) digestive system, specifically from disorders of the gut-brain interaction (DGBIs) in pediatrics and adults. With several indications in the market and additional clinical trials of Percutaneous Electrical Nerve Field Stimulation (PENFS) in multiple pediatric and adult conditions underway, we are focused on unmet GI healthcare needs in children and adults. We are dedicated to advancing science with our proprietary IB-Stim^® therapy, based on our PENFS technology, which was developed internally by the Company. We believe that superior science and evidence-based research are necessary for adoption by the medical and scientific community. Additional clinical trials of PENFS in multiple pediatric and adult conditions are underway, focused on unmet healthcare needs in children and adults. See “Our Pipeline” for more information.

Our first product, IB-Stim, is a PENFS technology intended to be used in patients 8 years and older with functional abdominal pain associated with irritable bowel syndrome (IBS), functional dyspepsia (FD) and associated FD nausea symptoms. IB-Stim is a US FDA Class II medical device that has received regulatory clearances: IB-Stim (DEN180057, 2019; K252024, 2025), under the regulation name of “non-implanted nerve stimulator for functional abdominal pain relief.”

Our second product, RED^TM (Rectal Expulsion Device), is indicated to evaluate the neuromuscular function of a patient’s ability to expel its contents from the rectum and as a qualitative test for rectal hypersensitivity. RED (K242304, 2024) helps identify patients with rectal hypersensitivity who experience a desire or urge to defecate at lower volumes of distension. RED is intended to be used in a clinical setting by trained health care providers in adult populations.

The Company’s product portfolio has achieved several key milestones, including:

RISK FACTORS

Investing in our securities involves a high degree of risk. You should consider carefully the risks described below, together with all of the other information included or incorporated by reference in this prospectus, including the risks and uncertainties discussed under “Risk Factors” in the Annual Report on Form 10-K for the period ended December 31, 2025, which has been filed with the SEC and is incorporated by reference in this prospectus, as well as any updates thereto contained in subsequent filings with the SEC or any free writing prospectus, before deciding whether to purchase our Securities in this offering. All of these risk factors are incorporated herein in their entirety. However, the risks incorporated by reference are not the only ones that we face. Additional risks not presently known to us or that we currently deem immaterial may also affect our business, operating results, prospects or financial condition. If any of these risks actually materialize, our business, prospects, financial condition, and results of operations could be seriously harmed. This could cause the trading price of our common stock to decline, resulting in a loss of all or part of your investment.

USE OF PROCEEDS

We will not receive any proceeds from the sale of common stock by the Selling Stockholders. All proceeds from the sale of the Selling Stockholder Shares will be paid directly to the Selling Stockholders.

SELLING STOCKHOLDERS

The Selling Stockholders are offering an aggregate of 1,923,194 shares of common stock consisting of:

(i) 849,212 shares of common stock issued to certain shareholders; (ii) 923,776 shares of common stock underlying restricted stock units (“RSUs”), and (iii) 150,206 shares of common stock issued to directors for their services as directors of the Company.

The Selling Stockholders may sell some, all or none of their Selling Stockholder Shares. Unless otherwise indicated in the footnotes below, the Selling Stockholders have not had any material relationship with us or any of our affiliates within the past three years other than as a security holder. To the best of our knowledge, the named parties in the table that follows are the beneficial owners and have the sole voting and investment power over all shares or rights to the Selling Stockholder Shares reported. None of the Selling Stockholders is a spouse or minor child of another Selling Stockholder.

We have prepared the following table based on written representations and information furnished to us by or on behalf of the Selling Stockholders. Unless otherwise indicated in the footnotes below, we believe that: (i) the Selling Stockholders are not a broker-dealer or affiliate of a broker-dealer, and (ii) the Selling Stockholders have not had direct or indirect agreements or understandings with any person to distribute their Selling Stockholder Shares. To the extent the Selling Stockholders identified below are, or are affiliated with, a broker-dealer, it could be deemed, to be an “underwriter” within the meaning of the Securities Act. Information about the Selling Stockholders may change over time.

The following table presents information regarding the Selling Stockholders and the Selling Stockholder Shares that they may offer and sell from time to time under this prospectus. The table is prepared based on information supplied to us by the Selling Stockholders, and reflects their respective holdings as of July 22, 2026, unless otherwise noted in the footnotes to the table. Beneficial ownership is determined in accordance with the rules of the SEC, and thus represents voting or investment power with respect to our securities. Under such rules, beneficial ownership includes any shares over which the individual has sole or shared voting power or investment power as well as any shares that the individual has the right to acquire within 60 days after the date of this table, to our knowledge and subject to applicable community property rules, the persons and entities named in the table have sole voting and sole investment power with respect to all equity interests beneficially owned.

PLAN OF DISTRIBUTION

We are registering the shares of common stock covered by this prospectus on behalf of the Selling Stockholders. All costs, expenses and fees connected with the registration of such securities will be borne by us. Any brokerage commissions and similar expenses connected with selling such shares of common stock will be borne by the Selling Stockholders according to the allocation of shares sold. The Selling Stockholders may offer and sell such securities and shares of common stock from time to time in one or more transactions. As used in this prospectus, the term “Selling Stockholders” includes pledgees, donees, transferees and other successors-in-interest who may acquire such shares of common stock through a pledge, gift, partnership distribution or other non-sale related transfer from the Selling Stockholders. The Selling Stockholders will act independently of the Company in making decisions with respect to the timing, manner and size of each sale. These transactions include the following methods of sale:

The Selling Stockholders may sell all or a portion of the Selling Stockholder Shares beneficially owned by them and offered hereby from time to time directly or through one or more broker-dealers or agents.

In connection with sales of shares of common stock covered by this prospectus, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of such shares of common stock in the course of hedging in positions they assume. The Selling Stockholders may also sell the shares of common stock covered by this prospectus short and the Selling Stockholders may deliver shares of common stock to close out short positions and to return borrowed shares of common stock in connection with such short sales. The Selling Stockholders may also loan or pledge shares of common stock covered by this prospectus to broker-dealers that in turn may sell such shares of common stock, 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 which require the delivery to such broker-dealer or other financial institution of shares of common stock covered by this prospectus, which shares of common stock such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock covered by this prospectus owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell such shares of common stock 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 successors in interest as Selling Stockholders under this prospectus. The Selling Stockholders may also transfer and donate shares of common stock covered by this prospectus 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.

A Selling Stockholder that is an entity may elect to make an in-kind distribution of shares of common stock covered by this prospectus to its members, general or limited partners or shareholders pursuant to the registration statement of which this prospectus is a part by delivering a prospectus. To the extent that such members, general or limited partners or shareholders are not affiliates of ours, such members, partners or shareholders would thereby receive freely tradable shares of common stock pursuant to the distribution through a registration statement. Additionally, to the extent that entities, members, partners or shareholders are affiliates of ours received shares in any such distribution, such affiliates will also be Selling Stockholders and will be entitled to sell such shares pursuant to this prospectus.

In effecting sales, the Selling Stockholders may engage broker-dealers or agents, who may in turn arrange for other broker-dealers to participate. Broker-dealers or agents may receive commissions, discounts or concessions from the Selling Stockholders and/or from the purchasers of shares of common stock covered by this prospectus for whom the broker-dealers may act as agents or to whom they sell as principal, or both. The compensation to a particular broker-dealer may be in excess of customary commissions. To our knowledge, there is currently no plan, arrangement or understanding between any Selling Stockholders and any broker-dealer or agent regarding the sale of any shares of common stock by the Selling Stockholders.

The Selling Stockholders, any broker-dealers or agents and any participating broker-dealers that act in connection with the sale of the shares of common stock covered by this prospectus may be “underwriters” under the Securities Act with respect to those shares of common stock and will be subject to the prospectus delivery requirements of the Securities Act. Any profit that the Selling Stockholders realize, and any compensation that any broker-dealer or agent may receive in connection with any sale, including any profit realized on resale of such shares of common stock acquired as principal, may constitute underwriting discounts and commissions. If the Selling Stockholders are deemed to be underwriters, the Selling Stockholders may be subject to certain liabilities under statutes including, but not limited to, Section 11, 12 and 17 of the Securities Act and Section 10(b) and Rule 10b-5 under the Exchange Act.

The securities laws of some states may require the Selling Stockholders to sell the shares of Common Stock covered by this prospectus in those states only through registered or licensed brokers or dealers. These laws may also require that we register or qualify such shares of common stock for sale in those states unless an exemption from registration and qualification is available and the Selling Stockholders and we comply with that exemption. In addition, the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares of common stock in the market and to the activities of the Selling Stockholders and their affiliates. Regulation M may restrict the ability of any person engaged in the distribution of shares of common stock to engage in market-making activities with respect to such shares of common stock. All of the foregoing may affect the marketability of the shares of common stock covered by this prospectus and the ability of any person to engage in market-making activities with respect to such shares.

If any Selling Stockholders notifies us that he has entered into any material arrangement with a broker-dealer for the sale of shares of common stock covered by this prospectus through a block trade, special offering, exchange distribution, over-the-counter distribution or secondary distribution, or a purchase by a broker or dealer, we will file any necessary supplement to this prospectus to disclose:

In addition, if the Selling Stockholders notifies us that a donee, pledgee, transferee or other successor-in-interest of the Selling Stockholders intends to sell any shares of common stock covered by this prospectus, we will file an amendment to the registration statement of which this prospectus forms a part of or a supplement to this prospectus, if required.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.

The following is an estimate of the expenses (all of which are to be paid by the Company) that we may incur in connection with the securities being registered hereby.

Item 15. Indemnification of Directors and Officers.

Section 145(a) of the DGCL provides, in general, that a corporation may indemnify any person who was or is a party to or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), because he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding, if he or she 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 corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

Section 145(b) of the DGCL provides, in general, that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor because the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if he or she 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 corporation, except that no indemnification shall be made with respect to any claim, issue or matter as to which he or she 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, he or she is fairly and reasonably entitled to indemnity for such expenses that the Court of Chancery or other adjudicating court shall deem proper.

Section 145(g) of the DGCL provides, in general, that a corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the power to indemnify the person against such liability under Section 145 of the DGCL.

Additionally, our bylaws eliminates our directors’ liability to the fullest extent permitted under the DGCL. The DGCL provides that directors of a corporation will not be personally liable for monetary damages for breach of their fiduciary duties as directors, except for liability:

If the DGCL is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of the Company’s directors will be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

We are also expressly authorized to carry directors’ and officers’ insurance to protect our directors, officers, employees and agents against liabilities for actions taken in their capacities as directors and officers.

Item 16. Exhibits and Financial Statement Schedules

Item 17. Undertakings.

The undersigned registrant hereby undertakes:

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b) (1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
