**UP TO 22,027,780 SHARES OF COMMON STOCK**

This prospectus relates to the offer and resale, from time to time, by the selling securityholders named in this prospectus (the "<u>Selling Securityholders</u>") of up to an aggregate of 22,027,780 shares of common stock, par value $0.01 per share, of Imunon, Inc. (the "<u>Common Stock</u>"), consisting of (i) 2,777,779 shares of Common Stock, (ii) up to 4,444,444 shares of Common Stock issuable upon the exercise of pre-funded warrants (the "<u>Pre-Funded Warrants</u>"), (iii) up to 14,444,446 shares of Common Stock issuable upon the exercise of common warrants (the "<u>Common Warrants</u>"), and (iv) 361,111 shares of Common Stock issuable upon the exercise of placement agent warrants (the "<u>Placement Agent Warrants</u>" and, together with the Pre-Funded Warrants and the Common Warrants, the "<u>Warrants</u>").

The shares of Common Stock being registered for resale by the Selling Securityholders in the registration statement of which this prospectus forms a part were issued and sold pursuant to a private placement (the "<u>Private Placement</u>"), which was priced at the market at a combined purchase price per share of Common Stock and accompanying Warrant of $0.45 and closed on May 27, 2025. The Common Warrants and Placement Agent Warrants will be exercisable upon receipt of Stockholder Approval (as defined below). We are filing the registration statement of which is prospectus is a part pursuant to the registration rights agreement (the "<u>Registration Rights Agreement</u>"), dated as of May 23, 2025, entered into with the purchasers in the Private Placement. In addition, the Company issued to the placement agent for the Private Placement the Placement Agent Warrants to purchase up to an aggregate of 361,111 shares of Common Stock, at an exercise price equal to $0.5625 per share.

We will not receive any proceeds from the sale of the shares by the Selling Securityholders. Our registration of the shares of Common Stock covered by this prospectus does not mean that the Selling Securityholders will offer or sell any of the shares of Common Stock.

We will bear all costs, expenses and fees in connection with the registration of the shares of Common Stock. The Selling Securityholders will bear all commissions and discounts, if any, attributable to their sales of the shares of Common Stock. The Selling Securityholders and any of their permitted transferees may offer and sell the shares covered by this prospectus in a number of different ways and at varying prices. The Securities and Exchange Commission may take a position that each of the Selling Securityholders is an "underwriter" within the meaning of Section 2(a)(11) of the Securities Act of 1933, as amended (the "<u>Securities Act</u>"). Additional information on the Selling Securityholders, and the times and manner in which they may offer and sell shares of our common stock under this prospectus, is provided under "*Selling Securityholders*" and "*Plan of Distribution*" in this prospectus.

**Business Overview**

Imunon is a clinical-stage biotechnology company focused on advancing a portfolio of innovative treatments that harness the body's natural mechanisms with the aim to generate safe, effective and durable responses across a broad array of human diseases, constituting a differentiating approach from conventional therapies. Imunon is developing its non-viral DNA technology across its modalities. The first modality, TheraPlas®, is developed for the coding of proteins and cytokines in the treatment of solid tumors where an immunological approach is deemed promising. The second modality, PlaCCine®, is developed for the coding of viral antigens that can elicit a strong immunological response. This technology may represent a promising platform for the development of vaccines in infectious diseases.

The Company's lead clinical program, IMNN-001, is a DNA-based immunotherapy for the localized treatment of advanced ovarian cancer that has completed multiple clinical trials including one Phase II clinical trial (OVATION 2). IMNN-001 works by instructing the body to produce safe and durable levels of powerful cancer-fighting molecules, such as interleukin-12 and interferon gamma, at the tumor site. Additionally, the Company has completed a first-in-human study of its COVID-19 booster vaccine (IMNN-101). The Company will continue to leverage these modalities and to advance, either directly or through partnerships, the technological frontier of plasmid DNA to better serve patients with difficult-to-treat conditions.

**Private Placement**

On May 23, 2025, the Company entered into a securities purchase agreement (the "<u>Purchase Agreement</u>") with certain institutional and accredited investors for the issuance and sale in the Private Placement of (i) 2,777,779 shares of Common Stock, (ii) Pre-Funded Warrants to purchase up to 4,444,444 shares of Common Stock, at an exercise price of $0.0001 per share, and (iii) Common Warrants to purchase up to 14,444,446 shares of Common Stock, at an exercise price of $0.45 per share. The Private Placement was priced at the market at a combined purchase price per share and accompanying Common Warrant of $0.45. The Private Placement closed on May 27, 2025.

The Pre-Funded Warrants are exercisable from the date of issuance until exercised in full. The Common Warrants will be exercisable upon receipt of such approval as may be required by the applicable rules and regulations of Nasdaq (or any successor entity) from the stockholders of the Company with respect to issuance of all of the Common Warrants and the shares of Common Stock upon the exercise thereof ("<u>Stockholder Approval</u>," and such date, the "<u>Stockholder Approval Date</u>") and have a term of three years from the Stockholder Approval Date. The Company agreed to hold a stockholder meeting on or prior to August 25, 2025 for the purpose of obtaining Stockholder Approval and to file a proxy statement for such meeting by June 16, 2025 and to use the record date that was previously set on May 13, 2025 for the stockholder meeting to seek Stockholder Approval. If the Company does not obtain Stockholder Approval at the first meeting, the Company will call a meeting every 90 days thereafter to seek Stockholder Approval until the earlier of the date on which Stockholder Approval is obtained or the Common Warrants are no longer outstanding. In the event that we are unable to obtain the required Stockholder Approval for the Common Warrants, such warrants will not be exercisable and therefore have no value.

A holder of the Pre-Funded Warrants and the Common Warrants may not exercise any portion of such holder's Pre-Funded Warrants or Warrants to the extent that the holder, together with its affiliates, would beneficially own more than 4.99% (or, at the election of the holder, 9.99%) of the Company's outstanding shares of Common Stock immediately after exercise, except that upon at least 61 days' prior notice from the holder to the Company, the holder may increase the beneficial ownership limitation to up to 9.99% of the number of shares of Common Stock outstanding immediately after giving effect to the exercise.

In connection with the Private Placement, the Company entered into the Registration Rights Agreement, dated as of May 23, 2025, with the purchasers in the Private Placement, pursuant to which the Company agreed to prepare and file a registration statement with the SEC registering the resale of the shares of Common Stock and the shares of Common Stock underlying the Pre-Funded Warrants and the Common Warrants.

H.C. Wainwright & Co., LLC acted as the Company's lead placement agent, and Brookline Capital Markets, a division of Arcadia Securities, LLC, acted as co-placement agent, in connection with the Private Placement, pursuant to that certain engagement letter, dated as of May 22, 2025, between the Company and H.C. Wainwright & Co., LLC (the "<u>Engagement Letter</u>"). In addition, the Company issued to designees of H.C. Wainwright & Co., LLC the Placement Agent Warrants to purchase up to an aggregate of 361,111 shares of Common Stock at an exercise price equal to $0.5625 per share. The Placement Agent Warrants have substantially the same terms as the Common Warrants and will be exercisable upon receipt of Stockholder Approval.

**Recent Developments**

On March 24, 2025, we issued a press release announcing finalization of our Phase 3 study design for IMNN-001, a treatment for women with newly diagnosed advanced ovarian cancer, and that the U.S. Food and Drug Administration is aligned with the protocol for the Phase 3 pivotal trial, called OVATION 3, of our lead candidate IMNN-001. On May 23, 2025, we issued a press release announcing new positive data from our Phase 2 OVATION 2 Study of IMNN-001, an investigational therapy for the treatment of advanced ovarian cancer.

On May 12, 2025, the Company entered into an exchange agreement (the "<u>Exchange Agreement</u>") with the holders (the "<u>Existing Warrant Holders</u>") of certain warrants of the Company (the "<u>Existing Warrants</u>") issued on August 1, 2024, which were exercisable for an aggregate of 5,000,000 shares of Common Stock. Pursuant to the terms of the Exchange Agreement, the Company issued to the Existing Warrant Holders an aggregate of 2,921,000 shares of Common Stock (the "<u>Warrant Exchange Shares</u>"), on a one-for-one basis, in exchange for shares issuable under the Existing Warrants (the "<u>Warrant Exchange</u>"), in reliance on an exemption from registration provided by Section 3(a)(9) of the Securities Act. The Warrant Exchange closed on May 13, 2025. The number of Warrant Exchange Shares issued pursuant to the Exchange Agreement represented 19.98% of the shares of Common Stock outstanding as of the date of the Exchange Agreement.

On May 19, 2025, the Company received a letter from the staff (the "<u>Staff</u>") of Nasdaq indicating that it is no longer in compliance with the minimum stockholders' equity requirement for continued listing pursuant to Nasdaq Listing Rule 5550(b)(1), which requires listed companies to maintain stockholders' equity of at least $2,500,000 or meet the alternative compliance standards relating to the market value of listed securities or net income from continuing operations, which the Company does not currently meet. Nasdaq's notice has no immediate effect on the listing of the Company's Common Stock on Nasdaq, which continues to trade under the symbol "IMNN." Pursuant to the notice and the Listing Rules of Nasdaq, Nasdaq has provided the Company with 45 calendar days, or until July 3, 2025, to submit a plan to regain compliance with the minimum stockholders' equity requirement. If the Company's plan to regain compliance is accepted, the Staff can grant an extension of up to 180 calendar days from the date of the Notice to evidence compliance. If the Company's plan to regain compliance is not accepted, or if it is accepted and the Company does not regain compliance in the timeframe required by Nasdaq, the Staff could provide notice that the Company's shares of common stock are subject to delisting. In such an event, the Company would have the right to request a hearing before a Nasdaq Hearings Panel. The Company is currently evaluating options to regain compliance and intends to timely submit a plan to regain compliance with the minimum stockholders' equity requirement. Although the Company intends to use all reasonable efforts to achieve compliance with the minimum stockholders' equity requirement, there can be no assurance that the Company will be able to regain compliance with the minimum stockholders' equity requirement or that the Company will otherwise be in compliance with other applicable Nasdaq listing criteria. The notice is unrelated to the Company's previously disclosed deficiency relating to Nasdaq's minimum bid price requirement.

On November 26, 2024, we received a notice from the Staff notifying us that, based upon the closing bid price of our Common Stock, for the 30 consecutive business days prior to the notice, we no longer met the requirement to maintain a minimum closing bid price of $1.00 per share, as set forth in Nasdaq Listing Rule 5550(a)(2). In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we were granted 180 calendar days, or until May 27, 2025, to regain compliance with the minimum bid price rule. To regain compliance, the closing bid price of our Common Stock was required to be $1.00 per share or more for a minimum of 10 consecutive business days at any time before May 27, 2025. As of May 27, 2025, we were not eligible for an additional 180 calendar day compliance period, as we did not meet the required Nasdaq initial listing standards, and, on May 28, 2025, we received a delisting notice from Nasdaq. We have requested an appeal with a Nasdaq Hearings Panel. There can be no assurance the Staff will grant our request for continued listing.

**RISK FACTORS**

Investing in our securities involves significant risk. Prior to making a decision about investing in our securities, you should carefully consider the specific factors discussed under the heading "*Risk Factors*" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 filed with the SEC on February 27, 2025 and other filings we make with the SEC from time to time, which are incorporated by reference herein in their entirety, together with other information in this prospectus and the information incorporated by reference herein. If any of these risks actually occurs, our business, financial condition, results of operations or cash flow could suffer materially. In such event, the trading price of our common stock could decline, and you might lose all or part of your investment.

**Risks Related Investing in our Common Stock**

 ****

***The sale or availability for sale of shares issuable pursuant to this prospectus may depress the price of our Common Stock, dilute the interest of our existing stockholders, and encourage short sales by third parties, which could further depress the price of our Common Stock.***

To the extent that the Selling Securityholders sell shares of our Common Stock pursuant to this prospectus, the market price of our Common Stock may decrease due to the additional selling pressure in the market. In addition, the dilution from exercise of the Warrants may cause stockholders to sell their shares of our Common Stock, which could further contribute to any decline in the price of our Common Stock. Any downward pressure on the price of our Common Stock caused by the sale or potential sale of such shares could encourage short sales by third parties. Such sales could place downward pressure on the price of our Common Stock by increasing the number of shares of our Common Stock being sold, which could further contribute to any decline in the market price of our Common Stock.

***Any market activity involving short selling or other market making activities could result in negative impact to the market price for our Common Stock.***

Short selling is a method used to capitalize on an expected decline in the market price of a security and could depress the price of our Common Stock, which could further increase the potential for future short sales. Sales of our Common Stock could encourage short sales by market participants, which could create negative market momentum. Continued short selling may bring about a temporary, or possibly long term, decline in the market price of our Common Stock. The Company cannot predict the size of future issuances or sales of Common Stock or the effect, if any, that future issuances and sales of Common Stock will have on its market price or the activities of short sellers. Sales involving significant amounts of Common Stock, including issuances made in the ordinary course of the Company's business, or the perception that such sales could occur, may materially and adversely affect prevailing market prices of the Common Stock.

***Our Common Stock may be delisted from Nasdaq if we fail to comply with continued listing standards.***

Our Common Stock is currently traded on Nasdaq under the symbol "IMNN." If we fail to comply with Nasdaq's continued listing standards, we may be delisted and our Common Stock will trade, if at all, only on the over-the-counter market, such as the OTC Bulletin Board or OTCQX market, and then only if one or more registered broker-dealer market makers comply with quotation requirements. In addition, delisting of our Common Stock could depress our stock price, substantially limit liquidity of our Common Stock and materially adversely affect our ability to raise capital on terms acceptable to us, or at all. Further, delisting of our Common Stock would likely result in our Common Stock becoming a "penny stock" under the Exchange Act.

On November 26, 2024, we received a notice from the Staff notifying us that, based upon the closing bid price of our Common Stock, for the 30 consecutive business days prior to the notice, we no longer met the requirement to maintain a minimum closing bid price of $1.00 per share, as set forth in Nasdaq Listing Rule 5550(a)(2). In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we were granted 180 calendar days, or until May 27, 2025, to regain compliance with the minimum bid price rule. To regain compliance, the closing bid price of our Common Stock was required to be $1.00 per share or more for a minimum of 10 consecutive business days at any time before May 27, 2025. As of May 27, 2025, we were not eligible for an additional 180 calendar day compliance period, as we did not meet the required Nasdaq initial listing standards, and, on May 28, 2025, we received a delisting notice from Nasdaq. We have requested an appeal with a Nasdaq Hearings Panel. There can be no assurance the Staff will grant our request for continued listing. In addition, on May 19, 2025, we received a notice from the Staff notifying us that, because our stockholders' equity was below $2.5 million as reported on our Quarterly Report on Form 10-Q for the quarter ended March 31, 2025, we no longer meet the minimum stockholders' equity requirement for continued listing on Nasdaq under Nasdaq Rule 5550(b)(1). Such notice is unrelated to our deficiency relating to Nasdaq's minimum bid price requirement and has no immediate effect on our continued listing on Nasdaq. For this deficiency, we have until July 3, 2025 to submit a plan to regain compliance. If such compliance plan is accepted, Nasdaq may grant an extension of 180 calendar days from the date of the notice. If the plan is not accepted, we may appeal the Staff's determination to a Nasdaq Hearings Panel. We are currently evaluating options to regain compliance and intend to timely submit a plan to regain compliance with the minimum stockholders' equity requirement. Although we intend to use all reasonable efforts to achieve compliance with all Nasdaq listing standards, there can be no assurance that we will be able to regain compliance with the listing standards or that we will otherwise be in compliance with other applicable Nasdaq listing criteria. Furthermore, Nasdaq may delist our Common Stock for public interest concerns, even if we are able to regain compliance for continued listing on Nasdaq under the minimum closing bid price and stockholders' equity listing requirements.

If our Common Stock were to be delisted by Nasdaq, it may be eligible for quotation on an over-the-counter quotation system or on the pink sheets. Upon any such delisting, our Common Stock would become subject to the regulations of the SEC relating to the market for penny stocks. A penny stock is any equity security not traded on a national securities exchange that has a market price of less than $5.00 per share. The regulations applicable to penny stocks may severely affect the market liquidity for our Common Stock and could limit the ability of stockholders to sell securities in the secondary market. In such a case, an investor may find it more difficult to dispose of or obtain accurate quotations as to the market value of our Common Stock, and there can be no assurance that our Common Stock will be eligible for trading or quotation on any alternative exchanges or markets.

Delisting from Nasdaq could adversely affect our ability to raise additional financing through public or private sales of equity securities, would significantly affect the ability of investors to trade our securities and would negatively affect the value and liquidity of our Common Stock. Delisting could also have other negative results, including the potential loss of confidence by employees, the loss of institutional investor interest and fewer business development opportunities.

***We will need to raise additional capital to fund our planned future operations, and we may be unable to secure such capital without significant dilutive financing transactions, or at all. If we are not able to raise additional capital, we may not be able to complete the development, testing and commercialization of our drug candidates and will not be able to continue as a going concern.***

We have not generated significant revenue and have incurred significant net losses in each year since our inception. For the quarter ended March 31, 2025 and the year ended December 31, 2024, we incurred a net loss of $4.1 million and $18.6 million, respectively, and used $2.8 million and $18.9 million, respectively, to fund operations. As of March 31, 2025, we have incurred approximately $411 million of cumulative net losses. As of March 31, 2025 and December 31, 2024, we had cash and cash equivalents of $2.9 million and $5.9 million, respectively.

We have substantial future capital requirements, including to continue our research and development activities and advance our drug candidates through various development stages, including the Phase 3 registrational trial of IMNN-001 in advanced ovarian cancer. We are unable to estimate the duration and completion costs of our research and development projects or when, if ever, and to what extent we will receive cash inflows from the commercialization and sale of a product. Our inability to complete any of our research and development activities, preclinical studies or clinical trials in a timely manner or our failure to enter into collaborative agreements when appropriate could significantly increase our capital requirements and could adversely impact our liquidity. While our estimated future capital requirements are uncertain and could increase or decrease as a result of many factors, including the extent to which we choose to advance our research, development activities, preclinical studies and clinical trials, or if we are in a position to pursue manufacturing or commercialization activities, we will need significant additional capital to develop our drug candidates through development and clinical trials, obtain regulatory approvals and manufacture and commercialize approved products, if any. We do not know whether we will be able to access additional capital when needed or on terms favorable to us or our stockholders. Our inability to raise additional capital, or to do so on terms reasonably acceptable to us, would jeopardize the future success of our business.

In addition, our unaudited financial statements for the quarter ended March 31, 2025 and our audited financial statements for the year ended December 31, 2024 were prepared under the assumption that we would continue as a going concern. However, we have concluded that there is substantial doubt about our ability to continue as a going concern, therefore our independent registered public accounting firm included a "going concern" explanatory paragraph in its report on our financial statements for the year ended December 31, 2024 included in our Annual Report on Form 10-K for the year ended December 31, 2024, indicating that, without additional sources of funding, our cash at December 31, 2024 is not sufficient for us to operate as a going concern for a period of at least one year from the date that the financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2024 were issued. Management's plans concerning these matters, including our need to raise additional capital, are described in the Quarterly Report on Form 10-Q for the quarter ended March 31, 2025 and the Annual Report on Form 10-K for the year ended December 31, 2024, however, management cannot assure you that its plans will be successful. If we cannot continue as a viable entity, our stockholders would likely lose most or all of their investment in us.

***We have never paid dividends on our capital stock, and we do not anticipate paying dividends in the foreseeable future.***

We have never paid dividends on any of our capital stock and currently intend to retain any future earnings to fund the growth of our business. We may also enter into credit agreements or other borrowing arrangements in the future that will restrict our ability to declare or pay cash dividends on our Common Stock. Any determination to pay dividends in the future will be at the discretion of our board of directors and will depend on our financial condition, operating results, capital requirements, general business conditions and other factors that our board of directors may deem relevant. As a result, capital appreciation, if any, of the securities will be the sole source of gain, if any, for the foreseeable future.

**CAUTIONARY NOTICE REGARDING FORWARD-LOOKING STATEMENTS**

 

Certain statements contained or incorporated by reference in this prospectus may constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and releases issued by the SEC and within the meaning of Section 27A of the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended (the "<u>Exchange Act</u>"). Forward-looking statements may relate to such matters as anticipated financial performance, business prospects, technological developments, product pipelines, clinical trials and research and development activities, the adequacy of capital reserves and anticipated operating results and cash expenditures, current and potential collaborations, strategic alternatives and other aspects of our present and future business operations and similar matters. These statements involve known and unknown risks, uncertainties and other factors, many of which are outside of our control, that may cause our or our industry's actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by such forward-looking statements. Such statements include, without limitation:

● any statements regarding future operations, plans, regulatory filings or approvals, including the plans and objectives of management for future operations or programs or proposed new products or services;

● any statements regarding the performance, or likely performance, or outcomes or economic benefit of any of our research and development activities, proposed or potential clinical trials or new drug filing strategies or timelines, including whether any of our clinical trials will be completed successfully within any specified time period or at all;

● any projections of earnings, cash resources, revenue, expense or other financial terms;

● any statements regarding the initiation, timing, progress and results of our research and development programs, preclinical studies, any clinical trials and Investigational New Drug application, New Drug Application and other regulatory submissions;

● any statements regarding cost and timing of development and testing, capital structure, financial condition, working capital needs and other financial items, including our ability to continue as a going concern;

● any statements regarding compliance with Nasdaq's listing standards and our ability to remain listed on Nasdaq; and

● any statements regarding future economic conditions or performance and any statement of assumptions underlying any of the foregoing.

In some cases, you can identify forward-looking statements by terminology such as "expect," "anticipate," "estimate," "continue," "plan," "believe," "could," "intend," "predict," "project," "may," "should," "will," "would" and words of similar import regarding our expectations. Forward-looking statements are only predictions. Actual events or results may differ materially. Although we believe that our expectations are based on reasonable assumptions within the bounds of our knowledge of our industry, business and operations, we cannot guarantee that actual results will not differ materially from our expectations. In evaluating such forward-looking statements, you should specifically consider various factors, including, but not limited to, the inherent uncertainty in the drug development process, our ability to raise additional capital to fund our planned future operations and continue as a going concern, our ability to obtain or maintain U.S. Food and Drug Administration and foreign regulatory approvals for our drug candidates, potential impact of the Russian invasion of Ukraine and the unrest in the Middle East on our business, our ability to enroll patients in our clinical trials, risks relating to third parties' conduct of our clinical trials, risks relating to government, private health insurers and other third-party payers coverage or reimbursement, risks relating to commercial potential of a drug candidate in development, changes in technologies for the treatment of cancer, impact of development of competitive drug candidates by others, risks relating to intellectual property, volatility in the market price of our Common Stock, potential inability remain listed on Nasdaq and the impact of adverse capital and credit market conditions. These and other risks and assumptions are outlined under "*Risk Factors*" contained in this prospectus and any related free writing prospectus, and in our most recent Annual Report on Form 10-K, as revised or supplemented by our subsequent Quarterly Reports on Form 10-Q, incorporated by reference into this prospectus, as well as any amendments thereto reflected in subsequent filings with the SEC. The discussion of risks and uncertainties set forth in this prospectus or referenced in those filings is not necessarily a complete or exhaustive list of all risks facing us at any particular point in time. We operate in a highly competitive, highly regulated and rapidly changing environment, and our business is in a state of evolution. Therefore, it is likely that new risks will emerge, and the nature and elements of existing risks will change. It is not possible for management to predict all such risk factors or changes therein or to assess either the impact of all such risk factors on our business or the extent to which any individual risk factor, combination of factors or new or altered factors may cause results to differ materially from those contained in any forward-looking statement. Forward-looking statements represent our estimates and assumptions only as of the date such forward-looking statements are made. You should carefully read this prospectus and any related free writing prospectus, together with the information incorporated herein or therein by reference as described under the section titled "*Incorporation of Certain Information by Reference,*" and with the understanding that our actual future results may materially differ from what we expect.

Forward-looking statements speak only as of the date they are made, and we assume no obligation to update any forward-looking statements publicly, or to update the reasons why actual results could differ materially from those anticipated in any forward-looking statements, even if new information becomes available, except as required by law.

**USE OF PROCEEDS**

All shares of our Common Stock offered by this prospectus are being registered for resale by the Selling Securityholders identified herein. We will not receive any of the proceeds from the sale of the shares of our Common Stock being offered for sale by the Selling Securityholders.

The shares of Common Stock covered by the registration statement of which this prospectus is a part includes 14,805,557 shares of Common Stock issuable upon exercise of the Common Warrants and the Placement Agent Warrants. If all such warrants are exercised in cash, then we will receive gross proceeds of approximately $6.7 million. Proceeds to us from the exercise of such warrants will be used for general corporate purposes, including working capital.

The Selling Securityholders will pay any underwriting discounts and commissions and expenses incurred by the Selling Securityholders for brokerage, accounting, tax or legal services or any other expenses incurred by the Selling Securityholders in disposing of the securities. We will bear the costs, fees and expenses incurred in effecting the registration of the shares of Common Stock 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.

**DIVIDEND POLICY**

We have never declared or paid any cash dividends on our Common Stock and we do not currently intend to pay any cash dividends on our Common Stock in the foreseeable future. We expect to retain all available funds and future earnings, if any, to fund the development and growth of our business. Any future determination to pay dividends, if any, on our Common Stock will be at the discretion of our board of directors and will depend on, among other factors, the terms of any outstanding preferred stock, our results of operations, financial condition, capital requirements and contractual restrictions.

**SELLING SECURITYHOLDERS**

This prospectus covers the resale or other disposition by the Selling Securityholders of the Common Stock and the shares of Common Stock underlying the Warrants that were issued and sold pursuant to the Private Placement. The Selling Securityholders listed in the table below may from time to time offer and sell any or all of the shares of Common Stock set forth below pursuant to this prospectus. When we refer to the "Selling Securityholders" in this prospectus, we refer to the persons listed in the table below and the permitted transferees that hold any of the Selling Securityholders' interest in the shares of Common Stock after the date of this prospectus.

The following table sets forth certain information concerning the Common Stock that may be offered from time to time by each Selling Securityholder pursuant to this prospectus. The number of shares beneficially owned by each Selling Securityholder is determined under rules issued by the SEC. Under these rules, beneficial ownership includes any shares as to which the individual or entity has sole or shared voting power or investment power. Percentage ownership is based on 20,319,511 shares of common stock outstanding as of May 28, 2025. In computing the number of shares beneficially owned by an individual or entity and the percentage ownership of that person or entity, shares of Common Stock subject to warrants or other rights held by such person or entity that are currently exercisable or convertible or will become exercisable or convertible or will vest within 60 days of such date are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person. The percentages included in the table below do not take into account the beneficial ownership limitations included in the Pre-Funded Warrants and the Common Warrants, which provide that a holder of such warrants may not exercise any portion of such holder's Pre-Funded Warrants or Common Warrants to the extent that the holder, together with its affiliates, would beneficially own more than 4.99% (or, at the election of the holder, 9.99%) of the Company's outstanding shares of Common Stock immediately after exercise, except that upon at least 61 days' prior notice from the holder to the Company, the holder may increase the beneficial ownership limitation to up to 9.99% of the number of shares of Common Stock outstanding immediately after giving effect to the exercise. Except as otherwise indicated, to our knowledge, each of the Selling Securityholders listed has sole voting and investment power with respect to the shares beneficially owned by the Selling Securityholder, subject to community property laws where applicable.

The Selling Securityholders identified below may have sold, transferred or otherwise disposed of all or a portion of their securities included in the table below in transactions exempt from the registration requirements of the Securities Act. Any changed or new information provided to us by the Selling Securityholders, including regarding the identity of, and the securities held by, each Selling Securityholder, will be set forth in a prospectus supplement or amendments to the registration statement of which this prospectus is a part, if and when necessary. A Selling Securityholder may sell all, some or none of such securities in this offering. See "*Plan of Distribution*." For purposes of this table, we have assumed that the Selling Securityholders will have sold all of the securities covered by this prospectus upon the completion of the offering.

The Selling Securityholders do not have, and within the past three years have not had, any position, office or other material relationship with us.

 and has sole voting and dispositive power over the securities held. The number of shares
 beneficially owned consists of shares of Common Stock issuable upon exercise of the Placement
 Agent Warrants, which were received as compensation in connection with the Private Placement.
 Each Selling Securityholder acquired the Placement Agent Warrants in the ordinary course
 of business and, at the time the Placement Agent Warrants were acquired, each Selling Securityholder
 had no agreement or understanding, directly or indirectly, with any person to distribute
 such securities. H.C. Wainwright & Co., LLC served as our lead placement agent in connection
 with the Private Placement, for which it received compensation.

**PLAN OF DISTRIBUTION**

Each Selling Securityholder of the shares of the securities and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on Nasdaq or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. A Selling Securityholder may use any one or more of the following methods when selling securities:

● ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

● block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

● purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

● an exchange distribution in accordance with the rules of the applicable exchange;

● privately negotiated transactions;

● settlement of short sales;

● in transactions through broker-dealers that agree with the Selling Securityholders to sell a specified number of such securities at a stipulated price per security;

● through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

● to or through one or more underwriters or dealers in a public offering and sale by them, whether individually or through an underwriting syndicate led by one or more managing underwriters;

● through agents;

● a combination of any such methods of sale; or

● any other method permitted pursuant to applicable law.

The Selling Securityholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus.

If underwriters are used in the sale of any securities, such securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions described above. Securities may be either offered to the public through underwriting syndicates represented by managing underwriters or directly by underwriters.

If a dealer is used in an offering of securities, the dealer may purchase the securities, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of sale.

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

Underwriters, dealers and agents may be entitled to indemnification by the Selling Securityholders and/or us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which the agents, broker-dealers or underwriters may be required to make in respect thereof.

Underwriters, dealers or agents may receive compensation in the form of discounts, concessions or commissions from the Selling Securityholders or the purchasers, as their agents in connection with the sale of securities. If the shares are sold through underwriters, broker-dealers or agents, the Selling Securityholders will be responsible for underwriting discounts or commissions or agent's commissions. These underwriters, dealers or agents may be considered to be underwriters under the Securities Act. As a result, discounts, commissions or profits on resale received by the underwriters, dealers or agents may be treated as underwriting discounts and commissions. Each accompanying prospectus supplement will identify any such underwriter, dealer or agent and describe any compensation received by them from the Selling Securityholders. Any initial public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time.

In connection with the sale of the securities or interests therein, the Selling Securityholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Securityholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Securityholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Securityholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. If the Selling Securityholders are deemed to be underwriters, the Selling Securityholders 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 Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed to indemnify the Selling Securityholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

We have agreed to keep this prospectus effective until all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect.

In order to comply with the securities laws of some states, if applicable, the shares may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the shares may not be sold unless they have been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Securityholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the common stock by the Selling Securityholders or any other person. We will make copies of this prospectus available to the Selling Securityholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

**DESCRIPTION OF CAPITAL STOCK**

The following summary of the general terms and provisions of our capital stock does not purport to be complete and is subject to, and qualified in its entirety by, reference to our Amended and Restated Certificate of Incorporation ("<u>Certificate of Incorporation</u>") and our Amended and Restated Bylaws ("<u>Bylaws</u>"), each of which is incorporated by reference as an exhibit to our most recent Annual Report filed with the SEC, and applicable provisions of the Delaware General Corporation Law (the "<u>DGCL</u>"). The summaries below do not purport to be complete statements of the relevant provisions of the Certificate of Incorporation, the Bylaws or the DGCL.

**Authorized Capital Stock**

Our authorized capital stock consists of 112,500,000 shares of Common Stock, par value $0.01 per share and 100,000 shares of preferred stock, par value $0.01 per share, all of which preferred stock is undesignated.

**Common Stock**

Holders of Common Stock are entitled to one vote for each share held of record on all matters submitted to a vote of stockholders and do not have cumulative voting rights. Subject to any preferential rights of any outstanding preferred stock, holders of Common Stock are entitled to receive ratably such dividends, if any, as may be declared from time to time by our board of directors out of funds legally available therefor. In the event of a dissolution, liquidation or winding-up of the Company, holders of Common Stock are entitled to share ratably in all assets remaining after payment of liabilities and any preferential rights of any outstanding preferred stock.

Holders of Common Stock have no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to our Common Stock. All outstanding shares of Common Stock are fully paid and non-assessable. The rights, preferences and privileges of the 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 which may be designated and issued in the future.

Our Common Stock is listed on Nasdaq under the symbol "IMNN."

**Transfer Agent and Registrar**

**Preferred Stock**

***Undesignated Preferred Stock***

Pursuant to our Certificate of Incorporation, our board of directors has the authority, without further action by the stockholders (unless such stockholder action is required by applicable law or Nasdaq rules), to designate and issue shares of preferred stock in one or more series, to establish from time to time the number of shares to be included in each such series, to fix the designations, powers (including voting), privileges, preferences and relative participating, optional or other rights, if any, of the shares of each such series and the qualifications, limitations or restrictions thereof and to increase or decrease the number of shares of any such series, but not below the number of shares of such series then outstanding.

We will fix the designations, powers (including voting), privileges, preferences and relative participating, optional or other rights, if any, of the preferred stock of each series, as well as the qualifications, limitations or restrictions thereof, in the certificate of designation relating to that series. The certificate of designation will describe the terms of the series of preferred stock. This description will include:

● the title and stated value;

● the number of shares we are offering;

● the liquidation preference per share;

● the purchase price;

● the dividend rate, period and payment date and method of calculation for dividends;

● whether dividends will be cumulative or non-cumulative and, if cumulative, the date from which dividends will accumulate;

● the procedures for any auction or remarketing, if any;

● the provisions for a sinking fund, if any;

● the provisions for redemption or repurchase, if applicable, and any restrictions on our ability to exercise those redemption and repurchase rights;

● any listing of the preferred stock on any securities exchange or market;

● whether the preferred stock will be convertible into or exchangeable for other securities and, if applicable, the conversion price, or how it will be calculated, and the conversion period;

● voting rights, if any, of the preferred stock;

● preemptive rights, if any;

● restrictions on transfer, sale or other assignment, if any;

● liability as to further calls or to assessment by the Company, if any;

● a discussion of any material U.S. federal income tax considerations applicable to the preferred stock;

● the relative ranking and preferences of the preferred stock as to dividend rights and rights if we liquidate, dissolve or wind up our affairs;

● any limitations on the issuance of any class or series of preferred stock ranking senior to or on a parity with the series of preferred stock as to dividend rights and rights if we liquidate, dissolve or wind up our affairs; and

● any other specific terms, preferences, rights or limitations of, or restrictions on, the preferred stock.

The DGCL provides that the holders of preferred stock will have the right to vote separately as a class or, in some cases, as a series on an amendment to our Certificate of Incorporation if the amendment would change the par value or, unless our Certificate of Incorporation provides otherwise, the number of authorized shares of the class or the powers, preferences or special rights of the class or series so as to adversely affect the class or series, as the case may be. This right is in addition to any voting rights that may be provided in the applicable certificate of designation.

Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of our Common Stock or other securities. Preferred stock could be issued quickly with terms designed to delay or prevent a change in control of our Company or make removal of management more difficult. Additionally, the issuance of preferred stock may have the effect of decreasing the market price of our Common Stock.

**Anti-Takeover Considerations and Special Provisions of Our Certificate of Incorporation, Our Bylaws and the Delaware General Corporation Law**

***Certificate of Incorporation and Bylaws***

A number of provisions of our Certificate of Incorporation and Bylaws concern matters of corporate governance and the rights of our stockholders. Provisions that grant our board of directors the ability to issue shares of preferred stock and to set the voting rights, preferences and other terms thereof may discourage takeover attempts that are not first approved by our board of directors, including takeovers that may be considered by some stockholders to be in their best interests, such as those attempts that might result in a premium over the market price for the shares held by stockholders. Certain provisions could delay or impede the removal of incumbent directors even if such removal would be beneficial to our stockholders, such as the classification of our board of directors and the lack of cumulative voting.

Since our board of directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management.

These provisions may have the effect of deterring hostile takeovers or delaying changes in our control or in our management. These provisions are intended to enhance the likelihood of continued stability in the composition of our board of directors and in the policies they implement and to discourage certain types of transactions that may involve an actual or threatened change of our control. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions also are intended to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of our shares that could result from actual or rumored takeover attempts.

These provisions also could discourage or make more difficult a merger, tender offer or proxy contest, even if they could be favorable to the interests of stockholders and could potentially depress the market price of our Common Stock. Our board of directors believes that these provisions are appropriate to protect our interests and the interests of our stockholders.

***Classification of Board; No Cumulative Voting***

Our Certificate of Incorporation and Bylaws provide for our board of directors to be divided into three classes, with staggered three-year terms. Only one class of directors is elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms. Because our stockholders do not have cumulative voting rights, our stockholders representing a majority of the shares of Common Stock outstanding will be able to elect all of our directors due to be elected at each annual meeting of our stockholders.

***Meetings of and Actions by Stockholders***

Our Bylaws provide that annual meetings of our stockholders may take place at the time and place designated by our board of directors. A special meeting of our stockholders may be called at any time by our board of directors, the chairman of our board of directors or the president. Our Bylaws provide that (i) our board of directors can fix separate record dates for determining stockholders entitled to receive notice of a stockholder meeting and for determining stockholders entitled to vote at the meeting; (ii) we may hold a stockholder meeting by means of remote communications; (iii) any stockholder seeking to have the stockholders authorize or take corporate action by written consent shall, by written notice to the secretary of the Company, request that the board of directors fix a record date, and that the board of directors shall adopt a resolution fixing the record date in all events within ten calendar days after a request is received; and (iv) a written consent of stockholders shall not be effective unless a written consent signed by a sufficient number of stockholders to take such action is received by us within 60 calendar days of the earliest dated written consent received.

***Advance Notice Requirements for Stockholder Proposals and Director Nominations***

Our Bylaws provide that stockholders seeking to bring business before an annual meeting of stockholders or to nominate candidates for election as directors at an annual meeting of stockholders must provide timely notice in writing. To be timely, a stockholder's notice must be delivered to, or mailed and received by, the secretary of the Company at our principal executive offices not later than the close of business on the 90th calendar day, nor earlier than the close of business on the 120th calendar day in advance of the date specified in the Company's proxy statement released to stockholders in connection with the previous year's annual meeting of stockholders. If the date of the annual meeting is more than 30 calendar days before or after such anniversary date, notice by the stockholder to be timely must be so not earlier than the close of business on the 120th calendar day in advance of such date of annual meeting and not later than the close of business on the later of the 90th calendar day in advance of such date of annual meeting or the tenth calendar day following the date on which public announcement of the date of the meeting is made. In no event shall the public announcement of an adjournment or postponement of an annual meeting commence a new time period (or extend any time period) for the giving of an advance notice by any stockholder. Any stockholder that proposes director nominations or other business must be a stockholder of record at the time the advance notice is delivered by such stockholder to us and entitled to vote at the meeting. Our Bylaws also specify requirements as to the form and content of a stockholder's notice. These provisions may preclude stockholders from bringing matters before an annual meeting of stockholders or from making nominations for the election of directors at an annual meeting of stockholders. Unless otherwise required by law, any director nomination or other business shall not be made or transacted if the stockholder (or a qualified representative of the stockholder) does not appear at the meeting to present the director nominee or other proposed business.

***Filling of Board Vacancies***

Our Certificate of Incorporation and Bylaws provide that the authorized size of our board of directors shall be determined by the board of directors by board resolution from time to time and that our board of directors has the exclusive power to fill any vacancies and newly created directorships resulting from any increase in the authorized number of directors and the stockholders do not have the power to fill such vacancies. Vacancies in our board of directors and newly created directorships resulting from any increase in the authorized number of directors on our board of directors may be filled by a majority of the directors remaining in office, even though that number may be less than a quorum of our board of directors, or by a sole remaining director. A director so elected to fill a vacancy shall serve for the remaining term of the predecessor he or she replaced and until his or her successor is elected and has qualified, or until his or her earlier resignation, removal or death.

***Amendment of the Certificate of Incorporation***

Our Certificate of Incorporation may be amended, altered, changed or repealed at a meeting of our stockholders entitled to vote thereon by the affirmative vote of a majority of the outstanding stock entitled to vote thereon and a majority of the outstanding stock of each class entitled to vote thereon as a class, in the manner prescribed by the DGCL.

***Amendment of the Bylaws***

Our Bylaws may be amended or repealed, or new Bylaws may be adopted, by either our board of directors or the affirmative vote of at least 66 2/3 percent of the voting power of our outstanding shares of capital stock.

***Section 203 of the Delaware General Corporation Law***

We are subject to Section 203 of the DGCL, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the date that such stockholder became an interested stockholder, with the following exceptions:

● Before such date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

● Upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85 percent of the voting stock of the corporation outstanding at the time the transaction began, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned (i) by persons who are directors and also officers and (ii) pursuant to employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; and

● On or after such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of at least 66 2/3 percent of the outstanding voting stock that is not owned by the interested stockholder.

In general, Section 203 defines a business combination to include the following:

● any merger or consolidation involving the corporation and the interested stockholder;

● any sale, lease, transfer, pledge or other disposition of ten percent or more of the assets of the corporation to or with the interested stockholder;

● subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;

● any transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation beneficially owned by the interested stockholder; and

● the receipt by the interested stockholder of the benefit of any loss, advances, guarantees, pledges or other financial benefits by or through the corporation.

In general, Section 203 of the DGCL defines an "interested stockholder" as an entity or person who, together with the entity's or person's affiliates and associates, beneficially owns, or is an affiliate of the corporation and within three years prior to the time of determination of interested stockholder status did own, 15 percent or more of the outstanding voting stock of the corporation.

A Delaware corporation may "opt out" of these provisions with an express provision in its Certificate of Incorporation. We have not opted out of these provisions, which may as a result, discourage or prevent mergers or other takeover or change of control attempts of us.
