PRELIMINARY PROSPECTUS, SUBJECT TO COMPLETION, DATED JANUARY 29, 2026

AIM IMMUNOTECH INC.

Subscription Rights to Purchase Up to 12,000 Units

Consisting of an Aggregate of Up to 12,000 Shares of Series G Convertible Preferred Stock

and Warrants to Purchase up to an aggregate of 19,992,000 Shares of Common Stock

at a Subscription Price of $1,000 Per Unit and

Up to 9,996,000 Shares of Common Stock Issuable upon the Conversion of

Series G Convertible Preferred Stock Included in the Units and

Up to 19,992,000 Shares of Common Stock Issuable upon the Exercise of

Warrants Included in the Units

This prospectus relates to our distribution to holders of our common stock and certain outstanding options and warrants, which options and warrants we refer to, collectively, as the Participating Securities, at no charge, non-transferable subscription rights to purchase units. Each unit, which we refer to as a Unit, consists of one share of Series G Convertible Preferred Stock, which we refer to as the Preferred Stock, and 1,666 warrants to purchase common stock, which we refer to as the Warrants. Each share of Preferred Stock is convertible, at the option of the holder at any time, into a number of shares of our common stock equal to the quotient of the stated value of the Preferred Stock ($1,000) divided by the Conversion Price (initially, $1.20 per share). Each Warrant will be exercisable for one share of our common stock at an exercise price of $1.20 per share from the date of issuance through its expiration five years from the date of issuance. The Conversion Price and exercise price of the Warrants herein are assumed and estimated prices. We refer to the offering that is the subject of this prospectus as the Rights Offering. In the Rights Offering, you will receive one subscription right, which we refer to as the Subscription Right, for every share of common stock (including each share of common stock issuable upon conversion of Participating Securities) owned at 5:00 p.m., Eastern Time, on February 10, 2026, the record date of the Rights Offering, or the Record Date. The Preferred Stock and the Warrants comprising the Units will separate upon the expiration of the Rights Offering and will be issued separately but may only be purchased as a Unit, and the Units will not trade as a separate security. The Subscription Rights will not be tradable.

The Conversion Price and Warrant exercise price in this Rights Offering will be determined at the time of pricing, and may be at a discount to the current market price at the time. Therefore, the assumed and estimated Conversion Price and Warrant exercise price used throughout this prospectus may not be indicative of the final prices. The final Conversion Price and Warrant exercise price will be determined through negotiation and based upon a number of factors, including our history and our prospects, the industry in which we operate, our past and present operating results, the previous experience of our executive officers and the general condition of the securities markets at the time of this Rights Offering.

Each Subscription Right will entitle you to purchase one Unit, which we refer to as the Basic Subscription Right, at a subscription price per Unit of $1,000, which we refer to as the Subscription Price. If you exercise your Basic Subscription Rights in full, and any portion of the Units remain available under the Rights Offering, you will be entitled to an over-subscription privilege to purchase a portion of the unsubscribed Units at the Subscription Price, subject to proration and ownership limitations, which we refer to as the Over-Subscription Privilege. Each Subscription Right consists of a Basic Subscription Right and an Over-Subscription Privilege, which we refer to as the Subscription Right.

The Subscription Rights will expire if they are not exercised by 5:00 p.m., Eastern Time, on February 27, 2026, unless the Rights Offering is extended or earlier terminated by us. If we elect to extend the Rights Offering, we will issue a press release announcing the extension no later than 9:00 a.m., Eastern Time, on the next business day after the most recently announced expiration date of the Rights Offering. We may extend the Rights Offering for additional periods in our sole discretion for any reason up to an additional 60 days. Once made, all exercises of Subscription Rights are irrevocable.

We have not entered into any standby purchase agreement or other similar arrangement in connection with the Rights Offering. The Rights Offering is being conducted on a best-efforts basis and there is no minimum amount of proceeds necessary to be received in order for us to close the Rights Offering.

We have engaged Maxim Group LLC to act as dealer-manager in the Rights Offering.

Investing in our securities involves a high degree of risk. See “Risk Factors” beginning on page 15 of this prospectus. You should carefully consider these risk factors, as well as the information contained in this prospectus, before you invest.

Broadridge Corporate Issuer Solutions, LLC, who we refer to as Broadridge, will serve as the subscription agent and information agent for the Rights Offering. The subscription agent will hold the funds we receive from subscribers until we complete, abandon or terminate the Rights Offering. If you want to participate in this Rights Offering and you are the record holder of your shares, we recommend that you submit your subscription documents to the subscription agent well before the deadline. If you want to participate in this Rights Offering and you hold shares of our common stock or Participating Securities through your broker, dealer, bank or other nominee, you should promptly contact your broker, dealer, bank or other nominee and submit your subscription documents in accordance with the instructions and within the time period provided by your broker, dealer, bank or other nominee. For a detailed discussion, see “The Rights Offering – The Subscription Rights.”

Our board of directors reserves the right to terminate the Rights Offering for any reason any time before the expiration of the Rights Offering. If we terminate the Rights Offering, all subscription payments received will be returned within 10 business days, without interest or deduction. We expect the Rights Offering to expire on or about February 27, 2026, subject to our right to extend the Rights Offering as described above, and that we would close on subscriptions as soon as practicable after such date.

Our common stock is listed on the NYSE American under the symbol “AIM.” On January 23, 2026, the last reported sale price of our common stock was $1.20 per share. There is no public trading market for the Preferred Stock or the Warrants and we do not expect a market to develop. In addition, we do not intend to apply for listing of the Preferred Stock or the Warrants on any securities exchange or recognized trading system. The Subscription Rights are non-transferrable and will not be listed for trading on the NYSE American or any other securities exchange or market. You are urged to obtain a current price quote for our common stock before exercising your Subscription Rights.

This summary contains basic information about us and this Rights Offering. Because it is a summary, it does not contain all of the information that you should consider before investing. Before you decide to invest in our Units, you should read this entire prospectus carefully, including the section entitled “Risk Factors” and any information incorporated by reference herein.

Company Overview

AIM ImmunoTech Inc. and its subsidiaries are an immuno-pharma company headquartered in Ocala, Florida, and focused on the research and development of therapeutics to treat multiple types of cancers, viral diseases and immune-deficiency disorders for which there are inadequate or unmet therapies. We have established a strong foundation of laboratory, pre-clinical and clinical data with respect to the development of nucleic acids and natural interferon to enhance the natural antiviral defense system of the human body, and to aid the development of therapeutic products for the treatment of certain cancers and chronic diseases.

AIM’s products are Ampligen (rintatolimod) and Alferon N Injection (Interferon alfa). The Company’s flagship product –Ampligen – is a double-stranded RNA (“dsRNA”) molecule being developed for globally important cancers, viral diseases and disorders of the immune system. Ampligen has not been approved by the FDA or marketed in the United States but is approved for commercial sale in the Argentine Republic for the treatment of severe Chronic Fatigue Syndrome (“CFS”).

The Company is currently proceeding primarily in five areas:

	●	Conducting clinical trials to evaluate the efficacy and safety of Ampligen for the treatment of pancreatic cancer.
	●	Evaluating Ampligen across multiple cancers as a potential therapy that modifies the tumor microenvironment with the goal of increasing anti-tumor responses to checkpoint inhibitors.
	●	Exploring Ampligen’s antiviral activities and potential use as a prophylactic or treatment for existing viruses, new viruses and mutated viruses thereof.
	●	Evaluating Ampligen as a treatment for myalgic encephalomyelitis/chronic fatigue syndrome (“ME/CFS”) and fatigue and/or the Post-COVID condition of fatigue.
	●	Evaluating Ampligen as a vaccine adjuvant in the combination of Ampligen and AstraZeneca’s FluMist as an intranasal vaccine for influenza, including avian influenza.

We are prioritizing activities in an order related to the stage of development, with those clinical activities such as pancreatic cancer having priority over other experimentation. We intend that priority clinical work be conducted in trials authorized by the FDA or European Medicines Agency (“EMA”), which trials support a potential future NDA.

Immuno-Oncology.

We are focused on pancreatic cancer because testing results to date — primarily conducted in the Netherlands — have been very promising. The Netherlands study generated statistically significant data indicating that Ampligen extended survival well beyond the Standard of Care (“SOC”), when compared to well-matched historical controls. These data support the proposition that Ampligen, when administered to either patients with locally advanced or metastatic pancreatic cancer after systemic chemotherapy, showed a statistically significant increase in survival rate. In October 2021, we and our Contract Research Organization, Amarex, submitted an IND application to the FDA for a planned Phase 2 study of Ampligen as a therapy for locally advanced or metastatic late-stage pancreatic cancer. In December 2021, the FDA responded with a Clinical Hold on the proposed study. We submitted our response to the FDA in February 2022. In March 2022, we received notification from the FDA that the Clinical Hold was released and cleared, meaning that we are now able to proceed with the study specifically to treat locally advanced pancreatic cancer patients. In August 2022, we received IRB approval of the trial protocol and so announced the trial’s commencement. In February 2025, we made a business decision to place screening/enrollment on hold and suspend the study. The study may be redesigned or amended, pending additional data from the ongoing DURIPANC clinical trial. (https://clinicaltrials.gov/ct2/show/NCT05494697).

The DURIPANC Study is a Phase 1b/2 investigator-sponsored clinical trial combining Ampligen with AstraZeneca’s anti-PD-L1 immune checkpoint inhibitor Imfinzi® (durvalumab) for the treatment of late-stage pancreatic cancer. In July 2025, we announced a positive mid-year safety and efficacy update that included treatment of 14 subjects. There has been no significant toxicity reported. Three of the 14 subjects (~21%) had progression free survival (PFS) >6 months with an additional 3 subjects (21%) not yet progressed. Overall survival (OS) of >6 months in majority of eligible subjects (64%). Up to 25 patients are expected to be enrolled in the Phase 2 portion of DURIPANC. Enrollment and dosing is ongoing in Phase 2. (https://clinicaltrials.gov/ct2/show/NCT05927142).

Ampligen appears in clinic testing to have potential for standalone efficacy in a number of other solid tumors. We have also seen success in increasing survival rates and efficacy in the treatment of animal tumors when Ampligen is used in combination with checkpoint blockade therapies. In fact, in March 2022 we announced interim data from an investigator-initiated, Phase 2, single-arm, efficacy/safety trial to evaluate the effectiveness of combining intensive locoregional intraperitoneal (IP) chemoimmunotherapy of cisplatin with IP Ampligen (TLR-3 agonist) and IV infusion of the checkpoint inhibitor pembrolizumab for patients with recurrent platinum-sensitive ovarian cancer. We believe that data from the study, which was conducted by the University of Pittsburgh Medical Center and funded by a Merck grant, demonstrated that when combining three drugs – Ampligen and pembrolizumab, which are both immune therapies, with cisplatin, a chemotherapy – evidence of increased biomarkers associated with T cell chemotaxis and cytolytic function has been seen. Importantly, increases of these biomarkers in the tumor microenvironment have been correlated with favorable tumor responses. In November 2025, we announced publication of an abstract presented at SITC on the completed trial. Of the 27 patients included in the trial, 24 were evaluable for response and of those 24 there were 5 patients with complete response and 7 patients with partial response for an Objective Response Rate (ORR) of 50%. These successes in the field of immuno-oncology have guided our efforts toward the potential use of Ampligen as a combinational therapy for the treatment of a variety of solid tumor types. The first of our patent applications in this space was granted by the Netherlands on March 15, 2021.

Ampligen as a Potential Antiviral

We have a research and pre-clinical history that indicates broad-spectrum antiviral capability of Ampligen in animals. We hope to demonstrate that it has the same effect in humans. To do this, among other things, we need a population infected with a virus. That is why our most recent antiviral focus has been on COVID-19 (the disease caused by SARS-CoV-2) and Long COVID. Previous animal studies yielded positive results utilizing Ampligen to treat numerous viruses, such as Western Equine Encephalitis Virus, Ebola, Vaccinia Virus (which is used in the manufacture of smallpox vaccine) and SARS-CoV-1. We have conducted experiments in SARS-CoV-2 showing Ampligen has a powerful impact on viral replication. The prior studies of Ampligen in SARS-CoV-1 animal experimentation may predict similar protective effects against SARS-CoV-2.

We announced in February 2025 our intention to pursue a study of a potential avian influenza combination therapy of Ampligen and AstraZeneca’s FluMist, a nasal spray vaccine that helps prevent seasonal influenza. The new proposed clinical trial would expand upon previous Company-sponsored clinical research at the University of Alabama-Birmingham (“UAB”), which indicated that intranasal delivery of Ampligen after the intranasal delivery of the FluMist seasonal influenza vaccine increased the immune response to seasonal variants in the vaccine by greater than four-fold and induced cross-reactive secretory Immunoglobulin A against highly pathogenic avian influenza virus strains H5N1, H7N9 and H7N3. We are seeking collaborative grants from government and industry to defray the cost of the study. We believe that this pre-clinical and clinical work to date – combined with the ever-growing threat of Avian influenza – strongly supports our decision to move forward with this second Ampligen and FluMist study in humans.

Ampligen as a Treatment for Post-COVID Conditions

In July 2023, we enrolled and dosed the first patient in our Phase 2 study evaluating Ampligen® as a potential therapeutic for people with post-COVID conditions (“AMP-518”). We announced in August 2023 that the study had met the planned enrollment of 80 subjects ages 18 to 60 years who have been randomized 1:1 to receive twice-weekly intravenous infusions of Ampligen or placebo for 12 weeks, with a follow-up phase of two weeks. All patients have completed the study, with topline data reported in February 2024.

In January 2025, we announced that the final Clinical Study results from AMP-518 had been posted to ClinicalTrials.gov. The results support our belief in Ampligen as a potential therapeutic for people with the moderate-to-severe Post-COVID condition of fatigue, and that this would be the likely subject population for any follow-up clinical trial.

Ampligen as a treatment for ME/CFS and Post-COVID Conditions

As of January 20, 2026, there were 4 patients enrolled in this open-label expanded access treatment protocol (including one patient with Post-COVID Conditions). AIM previously reported positive preliminary results based on data from the first four Post-COVID Condition patients enrolled in the study. The data show that, by week 12, compared to baseline, there was what the investigators considered a clinically significant decrease in fatigue-related measures and improvement in cognition. Eight such patients have been treated in the study to date.

Intellectual Property

We rely on a combination of patents, trademarks, trade secrets, nondisclosure agreements, proprietary information ownership agreements and other intellectual property measures to protect our intellectual property rights. We believe that to have a competitive advantage, we must continue to develop and maintain the proprietary aspects of our technologies.

Summary of the Rights Offering

Securities to be Offered		We are distributing to you, at no charge, one non-transferable Subscription Right to purchase one Unit for every share of our common stock (or share of common stock issuable upon exercise of the Participating Securities) that you owned on the Record Date. Each Unit consists of one share of our Preferred Stock and 1,666 Warrants. The Units will separate upon the closing of the Rights Offering and the Preferred Stock and Warrants will be issued separately, however, they may only be purchased as a Unit, and the Unit will not trade as a separate security.

Size of Offering		12,000 Units.

Subscription Price		$1,000 per Unit.

Series G Convertible Preferred Stock		Each share of Preferred Stock will be convertible, at the option of the holder at any time, into the number of shares of our common stock determined by dividing the $1,000 stated value per share of the Preferred Stock by a conversion price of $1.20 per share.

Warrants		Each Warrant entitles the holder to purchase one share of our common stock at an exercise price of $1.20 per share. The Warrants will be exercisable for cash, or, solely during any period when a registration statement for the exercise of the Warrants is not in effect, on a cashless basis, at any time and from time to time after the date of issuance.

Record Date		5:00 p.m., Eastern Time, February 10, 2026.

Basic Subscription Rights		Your Basic Subscription Right will entitle you to purchase one Unit at the Subscription Price. You may exercise your Basic Subscription Right for some or all of your Subscription Rights, or you may choose not to exercise your Subscription Rights. If you choose to exercise your Subscription Rights, there is no minimum number of Units you must purchase. We are distributing Basic Subscription Rights to purchase an aggregate of 14,733,187 Units, but are only selling 12,000 Units in the Rights Offering. In the event that the Rights Offering is over-subscribed, rights holders will be entitled to their pro rata portion of the Units.

Over-Subscription Privilege		If you exercise your Basic Subscription Rights in full, you may also choose to exercise an over-subscription privilege to purchase a portion of any Units that are not purchased by our other common stockholder or Participating Securities holders through the exercise of their Basic Subscription Rights, subject to proration and stock ownership limitations described elsewhere in this prospectus. The subscription agent will return any excess payments by mail without interest or deduction promptly after expiration of the subscription period.

Expiration Date		The Subscription Rights will expire at 5:00 p.m., Eastern Time, on February 27, 2026.

Procedure for Exercising Subscription Rights		To exercise your Subscription Rights, you must take the following steps: If you are a record holder, as of the Record Date, of our common stock or Participating Securities, you must deliver payment and a properly completed Rights Certificate to the subscription agent to be received before 5:00 p.m., Eastern Time, on February 27, 2026. You may deliver the documents and payments by first class mail or courier service. If you use first class mail for this purpose, we recommend using registered mail, properly insured, with return receipt requested. If as of the Record Date you are a beneficial owner of shares of common stock or Participating Securities that are registered in the name of a broker, dealer, bank or other nominee, you should instruct your broker, dealer, bank or other nominee to exercise your Subscription Rights on your behalf. Please follow the instructions of your nominee, who may require that you meet a deadline earlier than 5:00 p.m., Eastern Time, on February 27, 2026.

Payment Adjustments		If you send a payment that is insufficient to purchase the number of Units requested, or if the number of Units requested is not specified in the Rights Certificate, the payment received will be applied to exercise Subscription Rights to the extent of the payment. If the payment exceeds the amount necessary for the full exercise of your Subscription Rights, including any over-subscription privilege exercised and permitted, the excess will be returned to you promptly in cash. You will not receive interest or a deduction on any payments refunded to you under the Rights Offering.

Delivery of Shares and Warrants		As soon as practicable after the expiration of the Rights Offering, we expect to close on subscriptions and for the subscription agent to arrange for the issuance of the shares of Preferred Stock and Warrants purchased pursuant to the Rights Offering. All shares and Warrants that are purchased in the Rights Offering will be issued in book-entry, or uncertificated, form meaning that you will receive a direct registration, or DRS, account statement from our transfer agent as it relates to the Preferred Stock and the Warrants reflecting ownership of these securities if you are a holder of record. If you hold your shares or Participating Securities in the name of a bank, broker, dealer, or other nominee, DTC will credit your account with your nominee with the securities you purchased in the Rights Offering.

Non-transferability of Subscription Rights		The Subscription Rights may not be sold, transferred, assigned or given away to anyone. The Subscription Rights will not be listed for trading on any stock exchange or market.

Transferability of Warrants		The Warrants will be separately transferable following their issuance and through their expiration five years from the date of issuance.

No Board Recommendation		Our board of directors is not making a recommendation regarding your exercise of the Subscription Rights. You are urged to make your decision to invest based on your own assessment of our business and financial condition, our prospects for the future, the terms of the Rights Offering, the information in this prospectus and other information relevant to your circumstances. Please see “Risk Factors” for a discussion of some of the risks involved in investing in our securities.

No Revocation		Except as described below, all exercises of Subscription Rights are irrevocable, even if you later learn of information that you consider to be unfavorable to the exercise of your Subscription Rights.

Use of Proceeds		Assuming the exercise of Subscription Rights to purchase all Units of the Rights Offering, after deducting fees and expenses payable to the dealer-manager, before deducting other estimated expenses payable by us and excluding any proceeds received upon exercise of any Warrants, we estimate the net proceeds of the Rights Offering will be approximately $10.65 million. However, this Rights Offering is being conducted on a best efforts basis with no minimum number of exercised Subscription Rights or amount of proceeds as a condition to closing and with no back-stop to ensure that the Company receives a minimum amount of cash proceeds. Accordingly, the net proceeds, if any, that we may receive as a result of the exercise of Subscription Rights may be substantially less than as described above. We intend to use the net proceeds from the exercise of subscriptions for general corporate purposes – including clinical trial expenses and manufacturing expenses associated with prospective Phase 2/3 pancreatic cancer clinical trials – and allocate a portion of the net proceeds to repay, according to their terms, certain existing debt obligations. See “Use of Proceeds.”

Material U.S. Federal Income Tax Consequences		For U.S. federal income tax purposes, we do not believe you should recognize income or loss upon receipt or exercise of a Subscription Right, but the receipt and exercise of the Subscription Rights is unclear in certain respects. You should consult your own tax advisor as to the tax consequences of the Rights Offering considering your particular circumstances. See “Material U.S. Federal Income Tax Consequences.”

Extension, Amendment and Termination		Although we do not presently intend to do so, we may extend the Rights Offering for additional time in our sole discretion for any reason for up to an additional 60 days. For example, we may decide that changes in the market price of our common stock warrant an extension, or we may decide that the degree of stockholder participation in the Rights Offering is less than the level we desire. In the event that we decide to extend the Rights Offering and you have already exercised your Subscription Rights, your subscription payment will remain with the subscription agent until such time as the Rights Offering closes or is terminated. We also reserve the right to amend or modify the terms of the Rights Offering, as appropriate. Our board of directors may for any reason terminate the Rights Offering at any time before the expiration of the Rights Offering. In the event that the Rights Offering is cancelled, all subscription payments received by the subscription agent will be returned, without interest or deduction, as soon as practicable. If we should make any fundamental changes to the terms set forth in this prospectus, we will (i) file a post-effective amendment to the registration statement of which this prospectus forms a part, (ii) offer potential purchasers who have subscribed for rights the opportunity to cancel such subscriptions and issue a refund of any money advanced by such stockholder or eligible warrant holder, and (iii) recirculate an updated prospectus after the post-effective amendment is declared effective with the SEC.

QUESTIONS AND ANSWERS RELATING TO THE RIGHTS OFFERING

The following are examples of what we anticipate will be common questions about this Rights Offering. The answers are based on selected information included elsewhere in this prospectus. The following questions and answers do not contain all of the information that may be important to you and may not address all of the questions that you may have about the Rights Offering. This prospectus and the documents incorporated by reference into this prospectus contain more detailed descriptions of the terms and conditions of the Rights Offering and provides additional information about us and our business, including potential risks related to the Rights Offering, the Units offered hereby, and our business. We urge you to read this entire prospectus and the documents incorporated by reference into this prospectus.

Why are we conducting the Rights Offering?

We are conducting the Rights Offering to raise additional capital for general corporate purposes and to fund ongoing operations and expansion of our business.

What is a Unit?

Each Unit consists of one share of Series G Convertible Preferred Stock and 1,666 Warrants to purchase common stock, at a Subscription Price of $1,000 per Unit. No fractional Units will be issued. Each Warrant entitles you to purchase one share of common stock at an exercise price of $1.20 per share, from the date of issuance through its expiration five years after the date of issuance. Each share of Preferred Stock will have a stated value of $1,000 and will be convertible into shares of our common stock at the conversion price $1.20. The Preferred Stock do not generally have any voting rights and will not be certificated. The shares of Preferred Stock and Warrants that comprise each Unit are immediately separable and will be issued separately in this Rights Offering; however, they may only be purchased as a Unit, and the Units will not trade as a separate security.

What is the Rights Offering?

We are distributing, at no charge, to holders of our common stock and holders of the Participating Securities, as of the Record Date, non-transferable Subscription Rights to purchase Units at a price of $1,000 per Unit. The Subscription Rights will not be tradable. Each Unit consists of one share of our Preferred Stock and 1,666 Warrants. See “Are there risks in exercising my Subscription Rights?” below. Each Warrant will be exercisable for one share of our common stock. Upon expiration of the Rights Offering, the Preferred Stock and Warrants comprising the Units will immediately separate and will be issued separately but may only be purchased as a Unit, and the Units will not trade as a separate security. There is no public trading market for the Preferred Stock or the Warrants. We do not intend to apply for listing of the Preferred Stock or the Warrants on any securities exchange or recognized trading system. The common stock to be issued upon conversion of the Preferred Stock or exercise of the Warrants, like our existing shares of common stock, will be traded on the NYSE American under the symbol “AIM.” You will receive one Subscription Right for every share of common stock (including each share of common stock issuable upon conversion of Participating Securities) that you owned as of 5:00 p.m., Eastern Time, on the Record Date. Each Subscription Right entitles the record holder to a Basic Subscription Right and an Over-Subscription Privilege. The Subscription Rights will expire if they are not exercised by 5:00 p.m., Eastern Time, on February 27, 2026, unless we extend or earlier terminate the Rights Offering.

What are the Basic Subscription Rights?

For every share you owned (including each share of common stock issuable upon conversion of Participating Securities) as of the Record Date, you will receive one Basic Subscription Right, which gives you the opportunity to purchase one Unit, consisting of one share of our Preferred Stock and 1,666 Warrants, for a price of $1,000 per Unit. For example, if you owned 100 shares of common stock as of the Record Date, you will receive 100 Subscription Rights and will have the right to purchase 100 shares of our Preferred Stock and 166,600 Warrants to purchase 166,660 shares of our common stock for $1,000 per Unit (or a total payment of $100,000). You may exercise all or a portion of your Basic Subscription Rights or you may choose not to exercise any Basic Subscription Rights at all.

If you are a record holder of our common stock or Participating Securities, the number of shares you may purchase pursuant to your Basic Subscription Rights is indicated on the enclosed Rights Certificate. If you hold your shares of common stock or Participating Securities in the name of a broker, dealer, bank or other nominee who uses the services of the Depository Trust Company, or DTC, you will not receive a Rights Certificate. Instead, DTC will issue one Subscription Right to your nominee record holder for each share of our common stock (including each share of common stock issuable upon conversion of exercise of Participating Securities) that you beneficially own as of the Record Date. If you are not contacted by your nominee, you should contact your nominee as soon as possible.

What is the Over-Subscription Privilege?

If you exercise your Basic Subscription Rights in full, you may also choose to exercise your Over-Subscription Privilege to purchase a portion of any Units that are not purchased by other holders of common stock or Participating Securities and remain available under the Rights Offering. You should indicate on your Rights Certificate, or the form provided by your nominee if your shares are held in the name of a nominee, how many additional Units you would like to purchase pursuant to your Over-Subscription Privilege, which we refer to as your Over-Subscription Request.

Subject to stock ownership limitations, if enough Units are available, we will seek to honor your Over-Subscription Request in full. If Over-Subscription Requests exceed the number of Units available, however, we will allocate the available Units pro-rata among the stockholders and securities holders exercising the Over-Subscription Privilege in proportion to the number of shares of our common stock (including each share of common stock issuable upon exercise of Participating Securities) each of those stockholders and securities holders owned on the Record Date, relative to the number of shares (including each share of common stock issuable upon exercise of Participating Securities) owned on the Record Date by all record holders exercising the Over-Subscription Privilege. If this pro-rata allocation results in any stockholders or securities holders receiving a greater number of Units than the stockholder or securities holders subscribed for pursuant to the exercise of the Over-Subscription Privilege, then such stockholder or securities holder will be allocated only that number of Units for which the stockholder or securities holder oversubscribed, and the remaining Units will be allocated among all other stockholders and securities holders exercising the Over-Subscription Privilege on the same pro rata basis described above. The proration process will be repeated until all Units have been allocated. See “The Rights Offering- Limitation on the Purchase of Units” for a description of certain stock ownership limitations.

To properly exercise your Over-Subscription Privilege, you must deliver to the subscription agent the subscription payment related to your Over-Subscription Privilege before the Rights Offering expires. Because we will not know the total number of unsubscribed Units before the expiration of the Rights Offering, if you wish to maximize the number of Units you purchase pursuant to your Over-Subscription Privilege, you will need to deliver payment in an amount equal to the aggregate Subscription Price for the maximum number of Units available, assuming that no common or securities holders other than you has purchased any Units pursuant to such stockholder’s or securities holder’s Basic Subscription Right and Over-Subscription Privilege. See “The Rights Offering- The Subscription Rights-Over-Subscription Privilege.” To the extent you properly exercise your Over-Subscription Privilege for a number of Units that exceeds the number of unsubscribed Units available to you, any excess subscription payments will be returned to you within 10 business days after the expiration of the Rights Offering, without interest or deduction.

Broadridge, our subscription agent for the Rights Offering, will determine the allocation of Over-Subscription Requests based on the formula described above.

May the Subscription Rights that I exercise be reduced for any reason?

Yes. While we are distributing to holders of our common stock and holders of the Participating Securities, one Subscription Right for every share of common stock (including each share of common stock issuable upon exercise of Participating Securities) owned on the Record Date, we are only seeking to raise $12 million dollars in gross proceeds in this Rights Offering. As a result, based on 3,276,425 shares of common stock outstanding as of January 26, 2026, and the 11,456,762 shares issuable upon exercise of the Participating Securities, we would grant Subscription Rights to acquire 14,733,187 Units (which include additional Class E and F Warrants due to the distribution of a stock dividend on January 13, 2026 which caused a reset of these warrants) but will only accept subscriptions for 12,000 Units. Accordingly, enough Units may not be available to honor your subscription in full. If exercises of Basic Subscription Rights exceed the number of Units available in the Rights Offering, we will allocate the available Units pro-rata among the record holders exercising the Basic Subscription Rights in proportion to the number of shares of our common stock (including each share of common stock issuable upon exercise of Participating Securities) each of those record holders owned on the Record Date, relative to the number of shares owned on the Record Date by all record holders exercising the Basic Subscription Right. If this pro-rata allocation results in any record holders receiving a greater number of Units than the record holder subscribed for pursuant to the exercise of the Basic Subscription Rights, then such record holder will be allocated only that number of Units for which the record holder subscribed, and the remaining Units will be allocated among all other record holders exercising their Basic Subscription Rights on the same pro rata basis described above. The proration process will be repeated until all Units have been allocated. Please also see the discussion under “The Rights Offering-The Subscription Rights-Over-Subscription Privilege” and “The Rights Offering-Limitation on the Purchase of Units” for a description potential proration as to the Over-Subscription Privilege and certain stock ownership limitations.

If for any reason the number of Units allocated to you is less than you have subscribed for, then the excess funds held by the subscription agent on your behalf will be returned to you, without interest, as soon as practicable after the Rights Offering has expired and all prorating calculations and reductions contemplated by the terms of the Rights Offering have been effected, and we will have no further obligations to you.

What are the terms of the Series G Convertible Preferred Stock?

Each share of Preferred Stock will be convertible at the option of the holder at any time, into the number of shares of our common stock determined by dividing the $1,000 stated value per share of the Preferred Stock by a conversion price of $1.20 per share.

What are the terms of the Warrants?

Each Warrant entitles the holder to purchase one share of our common stock at an exercise price of $1.20 per share from the date of issuance through its expiration five years from the date of issuance. The Warrants will be exercisable for cash, or, solely during any period when a registration statement for the exercise of the Warrants is not in effect, on a cashless basis.

Are the Preferred Stock or the Warrants listed?

There is no public trading market for the Preferred Stock or Warrants. We do not intend to apply for listing of the Preferred Stock or the Warrants on any securities exchange or recognized trading system. The Preferred Stock and the Warrants will be issued in electronic form.

Will fractional shares be issued upon exercise of Subscription Rights, the conversion of Preferred Stock, or the exercise of Warrants?

No. We will not issue fractional shares of common stock in the Rights Offering. We will only distribute Subscription Rights to acquire whole Units, rounded down to the nearest whole number of underlying shares of common stock giving rise to such Subscription Rights. Any excess subscription payments received by the subscription agent will be returned within 10 business days after expiration of the Rights Offering, without interest or deduction.

Additionally, no fractional shares of common stock will be issued as a result of the conversion of shares of Preferred Stock or the exercise of Warrants. Instead, for any such fractional share that would otherwise have been issuable upon conversion of shares of Preferred Stock, we may, at our election, pay a cash payment equal to such fraction multiplied by the conversion price or round up to the next whole share, and for any such fractional share that would have otherwise been issued upon exercise of Warrants, we will round up such fraction to the next whole share.

What effect will the Rights Offering have on our outstanding common stock?

Assuming no other transactions by us involving our capital stock prior to the expiration of the Rights Offering, and if the Rights Offering is fully subscribed, upon consummation of the Rights Offering we will have 3,276,425 shares of common stock issued and outstanding, and 12,000 shares of Preferred Stock issued and outstanding convertible into an aggregate of 9,996,000 shares of our common stock, and Warrants to purchase an additional 19,992,000 shares of our common stock issued and outstanding. The exact number of shares of Preferred Stock and Warrants that we will issue in this Rights Offering will depend on the number of Units that are subscribed for in the Rights Offering.

How was the Subscription Price determined?

In determining the Subscription Price, the directors considered, among other things, the following factors:

	●	the current and historical trading prices of our common stock;

	●	the price at which stockholders might be willing to participate in the Rights Offering;

	●	the value of the common stock issuable upon conversion of the Preferred Stock being issued as a component of the Unit;

	●	the value of the Warrant being issued as a component of the Unit;

	●	our need for additional capital and liquidity;

	●	the cost of capital from other sources; and

	●	comparable precedent transactions, including the percentage of shares offered, the terms of the Subscription Rights being offered, the Subscription Price and the discount that the Subscription Price represented to the immediately prevailing closing prices for those offerings.

In conjunction with the review of these factors, the board of directors also reviewed our history and prospects, including our past and present earnings and cash requirements, our prospects for the future, the outlook for our industry and our current financial condition. The board of directors also believed that the Subscription Price should be designed to provide an incentive to our current stockholders to participate in the Rights Offering and exercise their Basic Subscription Right and their Over-Subscription Privilege.

The Subscription Price does not necessarily bear any relationship to any established criteria for value. You should not consider the Subscription Price as an indication of actual value of our company or our common stock. The market price of our common stock may decline during or after the Rights Offering. You should obtain a current price quote for our common stock and perform an independent assessment of our Preferred Stock and Warrants before exercising your Subscription Rights and make your own assessment of our business and financial condition, our prospects for the future, the terms of the Rights Offering, the information in this prospectus and the other considerations relevant to your circumstances. Once made, all exercises of Subscription Rights are irrevocable. In addition, there is no established trading market for the Preferred Stock or the Warrants to be issued pursuant to this Rights Offering, and the Preferred Stock and the Warrants may not be widely distributed.

Am I required to exercise all the Basic Subscription Rights I receive in the Rights Offering?

No. You may exercise any number of your Basic Subscription Rights, or you may choose not to exercise any Basic Subscription Rights. If you do not exercise any Basic Subscription Rights, the number of shares of our common stock you own (including each share of common stock issuable upon exercise of Participating Securities) will not change. However, if you choose to not exercise your Basic Subscription Rights in full and other holders of Subscription Rights do exercise, your proportionate ownership interest in our company will decrease. If you do not exercise your Basic Subscription Rights in full, you will not be entitled to exercise your Over-Subscription Privilege.

How soon must I act to exercise my Subscription Rights?

If you received a Rights Certificate and elect to exercise any or all of your Subscription Rights, the subscription agent must receive your completed and signed Rights Certificate and payment for both your Basic Subscription Rights and any Over-Subscription Privilege you elect to exercise before the Rights Offering expires on February 27, 2026, at 5:00 p.m., Eastern Time, unless we extend or earlier terminate the Rights Offering. If you hold shares of common stock or Participating Securities in the name of a broker, dealer, bank or other nominee, your nominee may establish a deadline before the expiration of the Rights Offering by which you must provide it with your instructions to exercise your Subscription Rights, along with the required subscription payment.

May I transfer my Subscription Rights?

No. The Subscription Rights may be exercised only by the common stock and Participating Securities holders to whom they are distributed, and they may not be sold, transferred, assigned or given away to anyone else, other than by operation of law. As a result, Rights Certificates may be completed only by the stockholder or securities holder who receives the certificate. We do not intend to apply for the listing of the Subscription Rights on any securities exchange or recognized trading market.

Will our directors and executive officers participate in the Rights Offering?

To the extent they hold common stock or Participating Securities as of the Record Date, our directors and executive officers will be entitled to participate in the Rights Offering on the same terms and conditions applicable to other Rights holders. Some of our officers and directors have indicated that they plan on participating in the Rights Offering. However, no assurance can be given as to whether these or other officers or directors will participate in the Rights Offering or the number of Units, if any, that they will purchase.

Are we requiring a minimum subscription to complete the Rights Offering?

There is no aggregate minimum we must receive to complete the Rights Offering.

Has the board of directors made a recommendation to stockholders regarding the Rights Offering?

No. Our board of directors is making no recommendation regarding your exercise of the Subscription Rights. Rights holders who exercise Subscription Rights will incur investment risk on new money invested. We cannot predict the price at which our shares of common stock will trade after the Rights Offering. There is no public trading market for the Preferred Stock or the Warrants. We do not intend to apply for listing of Preferred Stock or the Warrants on any securities exchange or recognized trading system. On January 23, 2026, the last reported sale price of our common stock on the NYSE American was $1.20 per share. You should make your decision based on your assessment of our business and financial condition, our prospects for the future, the terms of the Rights Offering, the information contained in this prospectus and other considerations relevant to your circumstances. See “Risk Factors” for discussion of some of the risks involved in investing in our securities.

How do I exercise my Subscription Rights?

If you are a common stock or Participating Securities holder of record (meaning you hold your shares of our common stock or Participating Securities in your name and not through a broker, dealer, bank or other nominee) and you wish to participate in the Rights Offering, you must deliver a properly completed and signed Rights Certificate, together with payment of the Subscription Price for both your Basic Subscription Rights and any Over-Subscription Privilege you elect to exercise, to the subscription agent before 5:00 p.m., Eastern Time, on February 27, 2026. If you are exercising your Subscription Rights through your broker, dealer, bank or other nominee, you should promptly contact your broker, dealer, bank or other nominee and submit your subscription documents and payment for the Units subscribed for in accordance with the instructions and within the time period provided by your broker, dealer, bank or other nominee.

What if my shares are held in “street name”?

If you hold your shares of our common stock or Participating Securities in the name of a broker, dealer, bank or other nominee, then your broker, dealer, bank or other nominee is the record holder of the shares you beneficially own. The record holder must exercise the Subscription Rights on your behalf. Therefore, you will need to have your record holder act for you.

If you wish to participate in this Rights Offering and purchase Units, please promptly contact the record holder of your shares or Participating Securities. We will ask the record holder of your shares or Participating Securities, who may be your broker, dealer, bank or other nominee, to notify you of this Rights Offering.

What form of payment is required?

You must timely pay the full Subscription Price for the full number of Units you wish to acquire pursuant to the exercise of Subscription Rights by delivering to the subscription agent a:

	●	personal check drawn on a U.S. bank;

	●	bank draft drawn on a U.S. bank; or

	●	wire transfer.

If you send payment by check, payment will not be deemed to have been delivered to the subscription agent until the check has cleared. As such, any payments made by personal check should be delivered to the subscription agent no fewer than three business days prior to the expiration date.

If you send a payment that is insufficient to purchase the number of Units you requested, or if the number of Units you requested is not specified in the forms, the payment received will be applied to exercise your Subscription Rights to the fullest extent possible based on the amount of the payment received.

Will I receive interest on any funds I deposit with the subscription agent?

No. You will not be entitled to any interest on any funds that are deposited with the subscription agent pending completion or cancellation of the Rights Offering. If the Rights Offering is cancelled for any reason, the subscription agent will return this money to subscribers, without interest or penalty, as soon as practicable.

When will I receive my new shares of Preferred Stock and Warrants?

As soon as practicable after the expiration of the Rights Offering, we expect to close on subscriptions and for the subscription agent to arrange for the issuance of the shares of Preferred Stock and Warrants purchased in the Rights Offering. At closing, all prorating calculations and reductions contemplated by the terms of the Rights Offering will have been effected and payment to us for the subscribed-for Units will have cleared. All shares of Preferred Stock and Warrants that you purchase in the Rights Offering will be issued in book-entry, or uncertificated, form meaning that you will receive a direct registration, or DRS, account statement from our transfer agent as it relates to the Preferred Stock and warrant agent as it relates to the Warrants reflecting ownership of these securities if you are a holder of record. If you hold your common stock or Participating Securities in the name of a broker, dealer, bank or other nominee, DTC will credit your account with your nominee with the securities you purchase in the Rights Offering. EQ is acting as the warrant agent in this Rights Offering.

After I send in my payment and Rights Certificate to the Subscription Agent, may I cancel my exercise of Subscription Rights?

No. Exercises of Subscription Rights are irrevocable, even if you later learn information that you consider to be unfavorable to the exercise of your Subscription Rights. You should not exercise your Subscription Rights unless you are certain that you wish to purchase Units at the Subscription Price.

How much will our company receive from the Rights Offering?

Assuming that all Units are sold in the Rights Offering, we estimate that the net proceeds from the Rights Offering will be approximately $10.65 million, based on the Subscription Price of $1,000 per Unit, after deducting fees and expenses payable to the dealer-manager, before deducting other estimated expenses payable by us and excluding any proceeds received upon exercise of any Warrants. If all Warrants included in the Units are exercised for cash at the exercise price of $1.20 per share, we will receive an additional $23.99 million. We intend to use the net proceeds from the exercise of subscriptions for general corporate purposes – including clinical trial expenses and manufacturing expenses associated with prospective Phase 2/3 pancreatic cancer clinical trials – and allocate a portion of the net proceeds to repay, according to their terms, certain existing debt obligations. See “Use of Proceeds.”

Are there risks in exercising my Subscription Rights?

Yes. The exercise of your Subscription Rights involves risks. Exercising your Subscription Rights involves the purchase of shares of our Preferred Stock and Warrants to purchase common stock and you should consider this investment as carefully as you would consider any other investment. In addition, a market for the Preferred Stock and Warrants does not exist and no assurance can be given that one will develop. We do not intend to apply for listing of the Preferred Stock or the Warrants on any securities exchange or recognized trading system. See “Risk Factors” for discussion of additional risks involved in investing in our securities.

Can the board of directors terminate, extend or amend the Rights Offering?

Yes. Our board of directors may decide to terminate the Rights Offering at any time and for any reason before the expiration of the Rights Offering. We also have the right to extend the Rights Offering for additional periods in our sole discretion for up to an additional 60 days. We do not presently intend to extend the Rights Offering. We will notify stockholders and the public if the Rights Offering is terminated or extended by issuing a press release announcing the extension no later than 9:00 a.m., Eastern Time, on the next business day after the most recently announced expiration date of the Rights Offering. In the event that we decide to extend the Rights Offering and you have already exercised your Subscription Rights, your subscription payment will remain with the subscription agent until such time as the Rights Offering closes or is terminated.

Our board of directors also reserves the right to amend or modify the terms of the Rights Offering in its sole discretion. If we should make any fundamental changes to the terms of the Rights Offering set forth in this prospectus, we will file a post-effective amendment to the registration statement in which this prospectus is included, offer potential purchasers who have subscribed for Rights the opportunity to cancel such subscriptions and issue a refund of any money advanced by such stockholder and recirculate an updated prospectus after the post-effective amendment is declared effective by the SEC. In addition, upon such event, we may extend the expiration date of the Rights Offering to allow holders of rights ample time to make new investment decisions and for us to recirculate updated documentation. Promptly following any such occurrence, we will issue a press release announcing any changes with respect to the Rights Offering and the new expiration date. The terms of the Rights Offering cannot be modified or amended after the expiration date of the Rights Offering. Although we do not presently intend to do so, we may choose to amend or modify the terms of the Rights Offering for any reason, including, without limitation, in order to increase participation in the Rights Offering. Such amendments or modifications may include a change in the Subscription Price, although no such change is presently contemplated. If we should make any fundamental changes to the terms set forth in this prospectus, we will (i) file a post-effective amendment to the registration statement of which this prospectus forms a part, (ii) offer potential purchasers who have subscribed for rights the opportunity to cancel such subscriptions, and (iii) issue a refund of any money advanced by such stockholder or eligible warrant holder and recirculate an updated prospectus after the post-effective amendment is declared effective with the SEC.

If the Rights Offering is not completed or is terminated, will my subscription payment be refunded to me?

Yes. The subscription agent will hold all funds it receives in a segregated bank account until completion of the Rights Offering. If we do not complete the Rights Offering, all subscription payments received by the subscription agent will be returned within 10 business days after the termination or expiration of the Rights Offering, without interest or deduction. If you own shares in “street name,” it may take longer for you to receive your subscription payment because the subscription agent will return payments through the record holder of your shares. In addition, if we should make any fundamental changes to the terms set forth in this prospectus, we will (i) file a post-effective amendment to the registration statement of which this prospectus forms a part, (ii) offer potential purchasers who have subscribed for rights the opportunity to cancel such subscriptions, and (iii) issue a refund of any money advanced by such stockholder or eligible securities holder and recirculate an updated prospectus after the post-effective amendment is declared effective with the SEC.

How do I exercise my Rights if I live outside the United States?

The subscription agent will hold Rights Certificates for stockholders having addresses outside the United States. To exercise Subscription Rights, foreign stockholders must notify the subscription agent and timely follow other procedures described in the section entitled “The Rights Offering - Foreign Stockholders.”

What fees or charges apply if I purchase shares in the Rights Offering?

We are not charging any fee or sales commission to issue Subscription Rights to you or to issue shares of Preferred Stock or Warrants to you if you exercise your Subscription Rights. If you exercise your Subscription Rights through a broker, dealer, bank or other nominee, you are responsible for paying any fees your broker, dealer, bank or other nominee may charge you.

What are the U.S. federal income tax consequences of receiving and/or exercising my Subscription Rights?

For U.S. federal income tax purposes, we do not believe you should recognize income or loss in connection with the receipt or exercise of Subscription Rights in the Rights Offering, but the receipt and exercise of the Subscription Rights is unclear in certain respects. You should consult your own tax advisor as to your tax consequences resulting from the receipt and exercise of Subscription Rights, including the receipt, ownership and disposition of our Preferred Stock, Warrants, and common stock received upon the conversion of Preferred Stock or the exercise of Warrants. For further information, see “Material U.S. Federal Income Tax Consequences.”

To whom should I send my forms and payment?

If your shares of common stock or Participating Securities are held in the name of a broker, dealer, bank or other nominee, then you should send your subscription documents and subscription payment to that broker, dealer, bank or other nominee. If you are the record holder, then you should send your subscription documents, Rights Certificate, and subscription payment to the subscription agent by hand delivery, first class mail or courier service to:

By USPS mail:

By UPS, FedEx, or Courier:

Broadridge, Inc.

Attn: BCIS Re-Organization Department

P.O. Box 1342

Brentwood, NY 11717-0718

Broadridge, Inc.

Attn: BCIS IWS

51 Mercedes Way

Edgewood, NY 11717

You or, if applicable, your nominee are solely responsible for completing delivery to the subscription agent of your subscription documents, Rights Certificate and payment. You should allow sufficient time for delivery of your subscription materials to the subscription agent and clearance of payment before the expiration of the Rights Offering at 5:00 p.m. Eastern Time on February 27, 2026.

Who is the dealer-manager?

Maxim Group LLC is acting as the sole dealer-manager for the Rights Offering. Under the terms and subject to the conditions contained in the dealer-manager agreement, the dealer-manager will use its best efforts to solicit the exercise of Subscription Rights. We have agreed to pay the dealer-manager certain fees for acting as dealer-manager and to reimburse the dealer-manager for certain out-of-pocket expenses incurred in connection with this Rights Offering. The dealer-manager is not underwriting or placing any of the Subscription Rights or the shares of our Preferred Stock or Warrants being issued in the Rights Offering and is not making any recommendation with respect to such Subscription Rights (including with respect to the exercise or expiration of such Subscription Rights), shares of Preferred Stock or Warrants.

RISK FACTORS

Investing in our securities involves a high degree of risk. Before making an investment decision with respect to our securities, we urge you to carefully consider the risks described in the “Risk Factors” section of our Annual Report on Form 10-K for the year ended December 31, 2024 and our subsequent Quarterly Reports on Form 10-Q, which are incorporated by reference into this prospectus. These risk factors relate to our business, intellectual property, regulatory matters, and ownership of our common stock. In addition, the following risk factors present material risks and uncertainties associated with the Rights Offering. The risks and uncertainties incorporated by reference into this prospectus or described below are not the only ones we face. Additional risks and uncertainties not presently known or which we consider immaterial as of the date hereof may also have an adverse effect on our business. If any of the matters discussed in the following risk factors were to occur, our business, financial condition, results of operations, cash flows or prospects could be materially adversely affected, the market price of our common stock could decline and you could lose all or part of your investment in our securities.

Risks Related to the Rights Offering

Our management will have broad discretion over the use of the net proceeds from this Right Offering, you may not agree with how we use the proceeds and the proceeds may not be invested successfully.

Our management will have broad discretion as to the use of the net proceeds from this Rights Offering and could use them for purposes other than those contemplated at the time of commencement of this Rights Offering. Accordingly, you will be relying on the judgment of our management regarding the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. It is possible that, pending their use, we may invest the net proceeds in a way that does not yield a favorable, or any, return for us. The failure of our management to use such funds effectively could have a material adverse effect on our business, financial condition, operating results and cash flows.

Your interest in our company may be diluted as a result of this Rights Offering.

Stockholders and securities holders who do not fully exercise their Subscription Rights should expect that they will, at the completion of this Rights Offering, own a smaller proportional interest in our company on a fully-diluted basis than would otherwise be the case had they fully exercised their Subscription Rights. Further, the shares issuable upon the conversion of the Preferred Stock and the exercise of and Warrants to be issued pursuant to the Rights Offering will dilute the ownership interest of stockholders not participating in this Rights Offering or holders of Warrants who have not exercised them.

Further, if you purchase Units in this Rights Offering at the Subscription Price, you may suffer immediate and substantial dilution in the net tangible book value of our common stock. See “Dilution” in this prospectus for a more detailed discussion of the dilution which may incur in connection with this Rights Offering.

Completion of the Rights Offering is not subject to us raising a minimum offering amount.

This Rights Offering is being conducted on a best efforts basis with no minimum number of exercised Subscription Rights or amount of proceeds as a condition to closing and with no back-stop to ensure that the Company receives a minimum amount of cash proceeds. Accordingly, we may raise significantly less proceeds than the maximum amount offered in the Rights Offering and investors in this Rights Offering will not receive a refund in the event that we do not sell all of the securities offered hereunder. Further, even if we raise the maximum amount of proceeds, the proceeds may not be sufficient to meet all of our business objectives, thereby increasing the risk to investors in this Rights Offering, including investing in a company that continues to require capital. Further, there is no assurance that alternative capital, if needed, would be available on terms acceptable to us, or at all. See “Use of Proceeds.”

This Rights Offering may cause the trading price of our common stock to decrease.

The Subscription Price, together with the number of shares of common stock issuable upon conversion of the Preferred Stock and exercise of the Warrants, respectively, we propose to issue and ultimately will issue if this Rights Offering is completed, may result in an immediate decrease in the market price of our common stock. This decrease may continue after the completion of this Rights Offering. If that occurs, you may have committed to buying shares of our common stock at a price greater than the prevailing market price. We cannot predict the effect, if any, that the availability of shares for future sale represented by the Warrants issued in connection with the Rights Offering will have on the market price of our common stock from time to time. Further, if a substantial number of Subscription Rights are exercised and the holders of the shares received upon exercise of those Subscription Rights or the related Warrants choose to sell some or all of the shares underlying the Subscription Rights or the related Warrants, the resulting sales could depress the market price of our common stock.

Holders of our Preferred Stock and Warrants will have no rights as a common stockholder until such holders convert or exercise their Preferred Stock or Warrants, respectively, and acquire our common stock.

Until holders of Preferred Stock or Warrants acquire shares of our common stock upon conversion or exercise of the Preferred Stock or Warrants, respectively, holders of such securities will have no rights with respect to the shares of our common stock underlying such Preferred Stock or Warrants. Upon conversion or exercise of the Preferred Stock or Warrants, respectively, the holders thereof will be entitled to exercise the rights of a common stockholder only as to matters for which the record date occurs after the exercise date. Prior to conversion, holders of Preferred Stock will have limited voting rights.

If we terminate this Rights Offering for any reason, we will have no obligation other than to return subscription monies within 10 business days.

We may decide, in our sole discretion and for any reason, to cancel or terminate the Rights Offering at any time prior to the expiration date. If this Rights Offering is cancelled or terminated, we will have no obligation with respect to Subscription Rights that have been exercised except to return within 10 business days, without interest or deduction, all subscription payments deposited with the subscription agent. If we terminate this Rights Offering and you have not exercised any Subscription Rights, such Subscription Rights will expire and be worthless.

The Subscription Price determined for this Rights Offering is not an indication of the fair value of our common stock.

In determining the Subscription Price, our board of directors considered a number of factors, including, but not limited to, our need to raise capital in the near term to continue our operations, the current and historical trading prices of our common stock, a price that would increase the likelihood of participation in the Rights Offering, the cost of capital from other sources, the value of the Preferred Stock and Warrants being issued as components of the Unit, and comparable precedent transactions. The Subscription Price does not necessarily bear any relationship to any established criteria for value. No valuation consultant or investment banker has opined upon the fairness or adequacy of the Subscription Price. You should not consider the Subscription Price as an indication of the value of our company or our common stock.

If you do not act on a timely basis and follow subscription instructions, your exercise of Subscription Rights may be rejected.

Holders of Subscription Rights who desire to purchase shares of our Preferred Stock and Warrants in this Rights Offering must act on a timely basis to ensure that all required forms and payments are actually received by the subscription agent prior to 5:00 p.m., Eastern Time, on the expiration date, unless extended. If you are a beneficial owner of shares of common stock or Participating Securities and you wish to exercise your Subscription Rights, you must act promptly to ensure that your broker, dealer, bank, trustee or other nominee acts for you and that all required forms and payments are actually received by your broker, dealer, bank, trustee or other nominee in sufficient time to deliver such forms and payments to the subscription agent to exercise the Subscription Rights granted in this Rights Offering that you beneficially own prior to 5:00 p.m., Eastern Time, on the expiration date, as may be extended. We will not be responsible if your broker, dealer, bank, trustee or other nominee fails to ensure that all required forms and payments are received by the subscription agent prior to 5:00 p.m., Eastern Time, on the expiration date.

If you fail to complete and sign the required subscription forms, send an incorrect payment amount, or otherwise fail to follow the subscription procedures that apply to your exercise in this Rights Offering, the subscription agent may, depending on the circumstances, reject your subscription or accept it only to the extent of the payment received. Neither we nor the subscription agent undertakes to contact you concerning an incomplete or incorrect subscription form or payment, nor are we under any obligation to correct such forms or payment. We have the sole discretion to determine whether a subscription exercise properly follows the subscription procedures.

You may not receive all of the Units for which you subscribe.

While we are distributing to holders of our common stock and Participating Securities, one Subscription Right for every share of common stock (including each share of common stock issuable upon exercise of Participating Securities) owned on the Record Date, we are only seeking to raise $12 million dollars in gross proceeds in this Rights Offering. As a result, based on 3,276,425 shares of common stock outstanding as of January 26, 2026, and the 11,456,762 shares issuable upon exercise of the Participating Securities, we would grant Subscription Rights to acquire 14,733,187 Units (which include additional Class E and F Warrants due to the distribution of a stock dividend on January 13, 2026 which caused a reset of these warrants) but will only accept subscriptions for 12,000 Units. Accordingly, enough Units may not be available to honor your subscription in full. If excess Units are available after the exercise of Basic Subscription Rights, holders who fully exercise their Basic Subscription Rights will be entitled to subscribe for an additional number of Units. Over-Subscription Privileges will be allocated pro rata among Rights holders who over-subscribed, based on the number of over-subscription Units to which they have subscribed. We cannot guarantee that you will receive any or the entire number of Units for which you subscribed. If for any reason the number of Units allocated to you is less than you have subscribed for, then the excess funds held by the subscription agent on your behalf will be returned to you, without interest, as soon as practicable after the Rights Offering has expired and all prorating calculations and reductions contemplated by the terms of the Rights Offering have been effected, and we will have no further obligations to you.

Unless we otherwise agree in writing, a person or entity, together with related persons or entities, may not exercise Subscription Rights (including Over-Subscription Privileges) to purchase Units that, when aggregated with their existing ownership, would result in such person or entity, together with any related persons or entities, owning in excess of 19.99% of our issued and outstanding shares of common stock following the closing of the transactions contemplated by this Rights Offering. If the number of shares allocated to you is less than your subscription request, then the excess funds held by the subscription agent on your behalf will be returned to you, without interest, as soon as practicable after the Rights Offering has expired and all prorating calculations and reductions contemplated by the terms of the Rights Offering have been effected, and we will have no further obligations to you.

If you make payment of the Subscription Price by personal check, your check may not clear in sufficient time to enable you to purchase shares in this Rights Offering.

Any personal check used to pay for shares of Preferred Stock and Warrants to be issued in this Rights Offering must clear prior to the expiration date of this Rights Offering, and the clearing process may require five or more business days. If you choose to exercise your Subscription Rights, in whole or in part, and to pay for shares of Preferred Stock and Warrants by personal check and your check has not cleared prior to the expiration date of this Rights Offering, you will not have satisfied the conditions to exercise your Subscription Rights and will not receive the shares of Preferred Stock and Warrants you wish to purchase.

The receipt of Subscription Rights may be treated as a taxable distribution to you.

We believe the distribution of the Subscription Rights in this Rights Offering should be a non-taxable distribution to holders of shares of common stock and holders of Participating Securities, under Section 305(a) of the Internal Revenue Code of 1986, as amended, or the Code. Please see the discussion under the heading “Material U.S. Federal Income Tax Consequences” below. This position is not binding on U.S. Internal Revenue Service (the “IRS”) or the courts, however. If this Rights Offering is deemed to be part of a “disproportionate distribution” under Section 305 of the Code, your receipt of Subscription Rights in this Rights Offering may be treated as the receipt of a taxable distribution to you equal to the fair market value of the Subscription Rights. Any such distribution would be treated as dividend income to the extent of our current and accumulated earnings and profits, if any, with any excess being treated as a return of capital to the extent thereof and then as capital gain. Each holder of shares of common stock and each holder of Participating Securities is urged to consult his, her or its own tax advisor with respect to the particular tax consequences of this Rights Offering.

Proposed legislation in the U.S. Congress, including changes in U.S. tax law, may adversely impact the Company and the value of our Subscription Rights, shares of our common stock and Preferred Stock, and Warrants.

Changes to U.S. tax laws (which changes may have retroactive application) could adversely affect the Company or holders of our Subscription Rights, shares of our common stock and Preferred Stock, and Warrants. In recent years, many changes to U.S. federal income tax laws have been proposed and made, and additional changes to U.S. federal income tax laws are likely to continue to occur in the future.

The U.S. Congress is currently considering numerous items of legislation which may be enacted prospectively or with retroactive effect, which legislation could adversely impact the Company’s financial performance and the value of our Subscription Rights, shares of our common stock and Preferred Stock and Warrants.

Exercising the Subscription Rights limits your ability to engage in certain hedging transactions that could provide you with financial benefits.

By exercising the Subscription Rights, you are representing to us that you have not entered into any short sale or similar transaction with respect to our common stock since the Record Date for the Rights Offering. This requirement prevents you from pursuing certain investment strategies that could provide you greater financial benefits than you might have realized if the Subscription Rights did not contain this requirement.

The Subscription Rights are not transferable, and there is no market for the Subscription Rights.

You may not sell, transfer, assign or give away your Subscription Rights. Because the Subscription Rights are non-transferable, there is no market or other means for you to directly realize any value associated with the Subscription Rights. You must exercise the Subscription Rights to realize any potential value from your Subscription Rights.

There is no public market for the Preferred Stock in this Rights Offering.

There is no established public trading market for the Preferred Stock, and we do not expect one to develop. In addition, we do not intend to apply for listing of the Preferred Stock on any securities exchange or recognized trading system. Purchasers of the Preferred Stock may be unable to resell their shares of Preferred Stock or sell them only at an unfavorable price for an extended period of time, if at all.

There is no public market for the Warrants in this Rights Offering.

There is no established public trading market for the Warrants, and we do not expect one to develop. In addition, we do not intend to apply for listing of the Warrants on any securities exchange or recognized trading system. Purchasers of the Warrants may be unable to resell their Warrants or sell them only at an unfavorable price for an extended period of time, if at all.

The market price of our common stock may never exceed the exercise price of the Warrants issued in connection with this Rights Offering.

The Warrants being issued in connection with this Rights Offering become exercisable upon issuance and will expire five years from the date of issuance. The market price of our common stock may never exceed the exercise price of the Warrants prior to their date of expiration. Any Warrants not exercised by their date of expiration will expire worthless and we will be under no further obligation to the Warrant holder.

The dealer-manager is not underwriting, nor acting as placement agent of, the Subscription Rights or the securities underlying the Subscription Rights.

Maxim Group LLC is acting as sole dealer-manager for the Rights Offering. As provided in the dealer-manager agreement, the dealer-manager will provide marketing assistance in connection with this Rights Offering. The dealer-manager is not underwriting or placing any of the Subscription Rights or the shares of our Preferred Stock or Warrants being issued in this Rights Offering and is not making any recommendation with respect to such Subscription Rights (including with respect to the exercise or expiration of such Subscription Rights), shares of Preferred Stock or Warrants. The dealer-manager will not be subject to any liability to us in rendering the services contemplated by the dealer-manager agreement except for any act of bad faith, gross negligence or willful misconduct by the dealer-manager. The Rights Offering may not be successful despite the services of the dealer-manager to us in this Rights Offering.

Since the Warrants are executory contracts, they may have no value in a bankruptcy or reorganization proceeding.

In the event a bankruptcy or reorganization proceeding is commenced by or against us, a bankruptcy court may hold that any unexercised Warrants are executory contracts that are subject to rejection by us with the approval of the bankruptcy court. As a result, holders of the Warrants may, even if we have sufficient funds, not be entitled to receive any consideration for their Warrants or may receive an amount less than they would be entitled to if they had exercised their Warrants prior to the commencement of any such bankruptcy or reorganization proceeding.

We may amend or modify the terms of the Rights Offering at any time prior to the expiration of the Rights Offering in our sole discretion.

Our board of directors reserves the right to amend or modify the terms of the Rights Offering in its sole discretion. If we should make any fundamental changes to the terms of the Rights Offering set forth in this prospectus, we will file a post-effective amendment to the registration statement in which this prospectus is included, offer potential purchasers who have subscribed for rights the opportunity to cancel such subscriptions and issue a refund of any money advanced by such stockholder and recirculate an updated prospectus after the post-effective amendment is declared effective by the SEC. In addition, upon such event, we may extend the expiration date of the Rights Offering to allow holders of rights ample time to make new investment decisions and for us to recirculate updated documentation. Promptly following any such occurrence, we will issue a press release announcing any changes with respect to the Rights Offering and the new expiration date. The terms of the Rights Offering cannot be modified or amended after the expiration date of the Rights Offering. Although we do not presently intend to do so, we may choose to amend or modify the terms of the Rights Offering for any reason, including, without limitation, in order to increase participation in the Rights Offering. Such amendments or modifications may include a change in the Subscription Price, although no such change is presently contemplated.

We are currently not in compliance with the NYSE American continued listing requirements. If we are unable to regain compliance with the NYSE American’s listing requirements, our securities could be delisted, which could affect our common stock market price and liquidity and reduce our ability to raise capital.

We are not currently in compliance with the NYSE American’s stockholders’ equity rule because our stockholders’ equity is less than the required minimum of $6,000,000. Pursuant to the letter from the NYSE American informing us of this non-compliance, we submitted a Plan to the NYSE American illustrating how we can regain compliance by June 11, 2026. On February 26, 2025, the NYSE American accepted our Plan to regain compliance by June 11, 2026. As of September 30, 2025, our stockholders’ deficit was approximately negative $6.1 million. We must increase our stockholders’ equity to be at least $6 million to regain compliance with this rule. If we are not able to raise sufficient capital in this offering and by other means, we may be unable to regain compliance with the NYSE American’s listing standards and our securities could be subject to delisting. We intend to take all reasonable measures available to regain compliance under the NYSE American’s listing rules and remain listed on the NYSE American. We and holders of our securities could be materially adversely impacted if our securities are delisted from the NYSE American. In particular:

● we may be unable to raise equity capital on acceptable terms or at all;

● the price of our common stock will likely decrease as a result of the loss of market efficiencies associated with the NYSE American and the loss of federal preemption of state securities laws;

● holders may be unable to sell or purchase our securities when they wish to do so;

● we may become subject to stockholder litigation;

● we may lose the interest of institutional investors in our common stock;

● we may lose media and analyst coverage;

● our common stock could be considered a “penny stock,” which would likely limit the level of trading activity in the secondary market for our common stock; and

● we would likely lose any active trading market for our common stock, as it may only be traded on one of the over-the-counter markets, if at all.

If we are not able to comply with the applicable continued listing requirements or standards of the NYSE American, our common stock could be delisted from the NYSE American.

Our common stock is listed on the NYSE American. In order to maintain this listing, we must maintain a certain share price, financial and share distribution targets, including maintaining a minimum amount of stockholders’ equity and a minimum number of public stockholders. In addition to these objective standards, the NYSE American may delist the securities of any issuer (i) if, in its opinion, the issuer’s financial condition and/or operating results appear unsatisfactory; (ii) if it appears that the extent of public distribution or the aggregate market value of the security has become so reduced as to make continued listing on the NYSE American inadvisable; (iii) if the issuer sells or disposes of principal operating assets or ceases to be an operating company; (iv) if an issuer fails to comply with the NYSE American’s listing requirements; (v) if an issuer’s securities sell at what the NYSE American considers a “low selling price” which the NYSE American generally considers $0.10 per share, the NYSE American may suspend trading of the common stock, until the issuer corrects this via a reverse split of shares after notification by the NYSE American; or (vi) if any other event occurs or any condition exists which makes continued listing on the NYSE American, in its opinion, inadvisable. There are no assurances how the market price of the common stock will be impacted in future periods as a result of the general uncertainties in the capital markets and any specific impact on our company as a result of the recent volatility in the capital markets.

In the event that our common stock is delisted from the NYSE American and is not eligible for quotation on another market or NYSE American, trading of our common stock could be conducted in the over-the-counter market or on an electronic bulletin board established for unlisted securities, such as the Pink Sheets or the OTC Markets. In such event, investors may face material adverse consequences, including, but not limited to, a lack of trading market for the common stock, reduced liquidity and market price of the common stock, decreased analyst coverage of the common stock, and an inability for us to obtain any additional financing to fund our operations that we may need.

If the common stock is delisted, the common stock may be subject to the so-called “penny stock” rules. The SEC has adopted regulations that define a penny stock to be any equity security that has a market price per share of less than $5.00, subject to certain exceptions, such as any securities listed on a national securities NYSE American. For any transaction involving a penny stock, unless exempt, the rules impose additional sales practice requirements and burdens on broker-dealers (subject to certain exceptions) and could discourage broker-dealers from effecting transactions in our stock, further limiting the liquidity of our shares, and an investor may find it more difficult to acquire or dispose of the common stock on the secondary market.

Risks Related to Our Business

Investors should carefully consider the risks and uncertainties and all other information contained or incorporated by reference in this prospectus, including the risks and uncertainties discussed under “Risk Factors” in our most recent Annual Report on Form 10-K, as may be amended from time to time, and in subsequent filings that are incorporated herein by reference. All these risk factors are incorporated by reference herein in their entirety. These risks and uncertainties are not the only ones facing us. Our business, financial condition or results of operations could be materially adversely affected by any of these risks. The trading price of our common stock could decline due to any of these risks, and you may lose all or part of your investment. This prospectus and the incorporated documents also contain forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks mentioned in this prospectus.

FORWARD-LOOKING STATEMENTS

This prospectus including reports and other documents incorporated by reference include “forward-looking statements,” as such term is used within the meaning of the Private Securities Litigation Reform Act of 1995. These “forward-looking statements” are not based on historical fact and involve assessments of certain risks, developments, and uncertainties in our business looking to the future. Such forward-looking statements can be identified by the use of terminology such as “may”, “will”, “should”, “expect”, “anticipate”, “estimate”, “intend”, “continue”, or “believe”, or the negatives or other variations of these terms or comparable terminology. Forward-looking statements may include projections, forecasts, or estimates of future performance and developments. Forward-looking statements contained in this prospectus are based upon assumptions and assessments that we believe to be reasonable as of the date of this prospectus. Whether those assumptions and assessments will be realized will be determined by future factors, developments, and events, which are difficult to predict and may be beyond our control. Actual results, factors, developments, and events may differ materially from those we assumed and assessed. Risks, uncertainties, contingencies and developments, including those identified in the “Risk Factors” section of this prospectus, in our most recent Annual Report on Form 10-K, subsequent Quarterly Reports on Form 10-Q and other filings we make with the SEC pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act, could cause our future operating results to differ materially from those set forth in any forward-looking statement. There can be no assurance that any such forward-looking statement, projection, forecast or estimate contained can be realized or that actual returns, results, or business prospects will not differ materially from those set forth in any forward-looking statement. Given these uncertainties, readers are cautioned not to place undue reliance on such forward-looking statements. We disclaim any obligation to update any such factors or to publicly announce the results of any revisions to any of the forward-looking statements contained herein to reflect future results, events or developments.

This prospectus and the documents incorporated herein by reference also refer to estimates and other statistical data made by independent parties and by us relating to market size and growth and other data about our industry. This data involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. In addition, projections, assumptions and estimates of our future performance and the future performance of the markets in which we operate are necessarily subject to a high degree of uncertainty and risk.

USE OF PROCEEDS

Assuming that all Units are subscribed for in the Rights Offering, we estimate that the net proceeds from the Rights Offering will be approximately $10.65 million, after deducting expenses relating to this Rights Offering payable by us estimated at approximately $1.4 million, including dealer-manager fees and expenses and excluding any proceeds received upon exercise of any Warrants. However, this Rights Offering is being conducted on a best efforts basis with no minimum number of exercised Subscription Rights or amount of proceeds as a condition to closing and with no back-stop to ensure that the Company receives a minimum amount of cash proceeds. Accordingly, the net proceeds, if any, that we may receive as a result of the exercise of Subscription Rights may be substantially less than as described above. We intend to use the net proceeds from the exercise of subscriptions for general corporate purposes – including clinical trial expenses and manufacturing expenses associated with prospective Phase 2/3 pancreatic cancer clinical trials – and allocate a portion of the net proceeds to repay, according to their terms, certain existing debt obligations. In this regard, there are two debt obligations. One is an unsecured note originally in the amount of approximately $3.3 million (inclusive of OID and investor legal fees of approximately $801 thousand). We are required to make monthly payments of up to $250 thousand. The other also is an unsecured note originally in the amount of approximately $3.3 million (inclusive of OID and investor legal fees of approximately $801 thousand). We are required to make monthly payments of up to $250 thousand. In addition, the second debt obligation requires us to repay from the proceeds of any future financings the lesser of 12.5% of the amount raised in such transaction or the balance of the amount due under the debt obligation.

We expect to use any proceeds we receive from the exercise of Warrants for substantially the same purposes and in substantially the same manner. Pending these uses, we intend to invest the funds in short-term, investment grade, interest-bearing securities. It is possible that, pending their use, we may invest the net proceeds in a way that does not yield a favorable, or any, return for us.

Our management will have broad discretion as to the allocation of the net proceeds from this Rights Offering and could use them for purposes other than those contemplated at the time of commencement of this Rights Offering.

DILUTION

Purchasers of Units in the Rights Offering will experience an immediate dilution of the net tangible book value per share of our common stock. Our net tangible book value as of September 30, 2025 was approximately negative $8,117,686, or negative $2.94 per share of our common stock (based upon 2,764,188 shares of our common stock outstanding on September 30, 2025). Net tangible book value per share is equal to our total tangible assets less our total liabilities, divided by the number of shares of our outstanding common stock.

Dilution per share of common stock equals the difference between the amount paid by purchasers of Units in the Rights Offering (ascribing no value to the Warrants or Preferred Stock contained in the Units) and the net tangible book value per share of our common stock immediately after the Rights Offering.

Based on the sale by us in this Rights Offering of a maximum of Units at the Subscription Price of $1,000 per Unit (assuming no conversion of the Preferred Stock and no exercise of the Warrants), and after deducting estimated offering expenses and dealer-manager fees and expenses payable by us, our pro forma net tangible book value as of September 30, 2025 would have been approximately $2,530,396, or $0.20 per share. This represents an immediate increase in pro forma net tangible book value to existing stockholders of $3.14 per share and an immediate dilution to purchasers in the Rights Offering of $1.00 per share. The following table illustrates this per-share dilution:

Subscription Price	$	1,000.00
Net tangible book value per share as of September 30, 2025	$	(2.94	)
Increase in net tangible book value per share attributable to Rights Offering	$	3.14
Pro forma net tangible book value per share as of September 30, 2025, after giving effect to Rights Offering	$	0.20
Dilution in net tangible book value per share to purchasers in the Rights Offering	$	1.00

The information above is as of September 30, 2025 and excludes:

	●	1,175 shares of our common stock issuable upon exercise of outstanding options granted under our 2009 equity incentive plan at a weighted average exercise price of $1,753.51 per share; and 28,138 shares of our common stock issuable upon exercise of outstanding options granted under our 2018 equity incentive plan at a weighted average exercise price of $153.70 per share;

	●	19,915 shares of our common stock available for issuance or future grant pursuant to our 2018 equity incentive plan;

	●	3,600 shares of our common stock issuable upon exercise of outstanding options granted to our consultant, Azenova, LLC at a weighted average exercise price of $46.00 per share;

	●	112,819 shares of our common stock issuable upon exercise of outstanding A and B warrants issued to an accredited investor at a weighted average exercise price of $36.30 per share;

	●	93,061 shares of our common stock issuable upon exercise of outstanding C and D warrants issued to the accredited investor in an offering at a weighted average exercise price of $28.00 per share;

	●	4,000,000 shares of our common stock issuable upon exercise of outstanding E & F warrants issued to the accredited investor in an offering at a weighted average exercise price of $6.35 per share.

MARKET PRICE AND DIVIDEND POLICY

Our shares of common stock are currently quoted on the NYSE American under the symbol “AIM”. On January 23, 2026, the last reported sales price of our common stock on the NYSE American was $1.20.

Holders of Record

As of January 26, 2026, we had approximately 27 holders of record of our common stock. Because many of our shares of common stock are held by brokers and other institutions on behalf of stockholders, this number is not indicative of the total number of stockholders represented by these stockholders of record.

Dividends

On January 13, 2026, we distributed one share of our common stock for every 1,000 shares of common stock issued and outstanding as of January 9, 2026 as well as one share of common stock for every 1,000 outstanding options or 1,000 warrants that has a right to receive stock dividends. Aside from that, we have not declared or paid dividends to stockholders since inception and do not plan to pay dividends in the foreseeable future. We currently intend to retain earnings, if any, to finance our growth.

Issuer Purchases of Equity Securities

None.

THE RIGHTS OFFERING

The Subscription Rights

We are distributing to the record holders of our common stock and Participating Securities, at no charge, non-transferable Subscription Rights to purchase one Unit at a Subscription Price of $1,000 per Unit. Each Basic Subscription Right will entitle you to purchase one share of our Preferred Stock and 1,666 Warrants. Each Warrant will be exercisable for one share of our common stock at an exercise price of $1.20 per share from the date of issuance through the expiration five years from the date of issuance. Each record holder of our common stock and Participating Securities will receive one Subscription Right for every share of our common stock (including each share of common stock issuable upon exercise of Participating Securities) owned by such record holder as of the Record Date. Each Subscription Right entitles the record holder to a Basic Subscription Right and an Over-Subscription Privilege.

Basic Subscription Rights

Your Basic Subscription Rights will entitle you to purchase Units, each comprised of one share of our Preferred Stock and 1,666 Warrants. For example, if you owned 100 shares of common stock as of the Record Date, you will receive 100 Subscription Rights and will have the right to purchase 100 shares of our Preferred Stock and Warrants to purchase 166,600 shares of our common stock for $1,000 per Unit, or a total payment of $100,000. You may exercise all or a portion of your Basic Subscription Rights, or you may choose not to exercise any of your Basic Subscription Rights. If you do not exercise your Basic Subscription Rights in full, you will not be entitled to exercise your Over-Subscription Privilege.

Additionally, sufficient Units may not be available to honor your Basic Subscription Right in full. While we are distributing one Subscription Right for every share of common stock owned or deemed owned on the Record Date, we are only seeking to raise $12 million dollars in gross proceeds in this Rights Offering. As a result, based on (1) 3,276,425 shares of common stock outstanding and (2) 11,456,762 shares issuable upon exercise of Participating Securities, we would grant 14,733,187 Subscription Rights to acquire Units but will only accept subscriptions for 12,000 Units.

If exercises of Basic Subscription Rights exceed the number of Units available in the Rights Offering, we will allocate the available Units pro-rata among the record holders exercising the Basic Subscription Rights in proportion to the number of shares of our common stock each of those record holders owned or were deemed to own on the record date, relative to the number of shares owned or deemed owned on the record date by all record holders exercising the Basic Subscription Right. If this pro-rata allocation results in any record holders receiving a greater number of Units than the record holder subscribed for pursuant to the exercise of the Basic Subscription Rights, then such record holder will be allocated only that number of Units for which the record holder subscribed, and the remaining Units will be allocated among all other record holders exercising their Basic Subscription Rights on the same pro rata basis described above. The proration process will be repeated until all shares have been allocated.

Over-Subscription Privilege

If you exercise your Basic Subscription Rights in full, you may also choose to exercise your Over-Subscription Privilege. Subject to proration and the limitations described in this prospectus, we will seek to honor the Over-Subscription Requests in full. If Over-Subscription Requests exceed the number of Units available, however, we will allocate the available Units pro rata among the common stock and eligible Participating Securities holders as of the Record Date exercising the Over-Subscription Privilege in proportion to the number of shares of our common stock (including each share of common stock issuable upon exercise of Participating Securities) each of those stockholders and/or securities holders owned on the Record Date, relative to the number of shares owned on the Record Date by all stockholders and securities holders as of the Record Date exercising the Over-Subscription Privilege. If this pro rata allocation results in any stockholder or securities holder receiving a greater number of Units than the record holder subscribed for pursuant to the exercise of the Over-Subscription Privilege, then such record holder will be allocated only that number of Units for which the record holder oversubscribed, and the remaining Units will be allocated among all other stockholders or securities holders exercising the Over-Subscription Privilege on the same pro rata basis described above. The proration process will be repeated until all Units have been allocated. Broadridge, the subscription agent for the Rights Offering, will determine the over-subscription allocation based on the formula described above.

To the extent the aggregate subscription payment of the actual number of unsubscribed Units available to you pursuant to the Over-Subscription Privilege is less than the amount you actually paid in connection with the exercise of the Over-Subscription Privilege, you will be allocated only the number of unsubscribed Units available to you, and any excess subscription payments will be returned to you, without interest or deduction, with 10 business days after expiration of the Rights Offering.

We can provide no assurances that you will be entitled to purchase the number of Units issuable upon the exercise of your Over-Subscription Privilege in full at the expiration of the Rights Offering. We will not be able to satisfy any requests for Units pursuant to the Over-Subscription Privilege if all of our stockholders exercise their Basic Subscription Rights in full, and we will only honor an Over-Subscription Privilege to the extent sufficient Units are available following the exercise of Basic Subscription Rights.

Limitation on the Purchase of Units

You may only purchase the number of Units purchasable upon exercise of the number of Basic Subscription Rights distributed to you in the Rights Offering, plus the Over-Subscription Privilege, if any. Accordingly, the number of Units that you may purchase in the Rights Offering is limited by the number of shares of our common stock (including each share of common stock issuable upon exercise of Participating Securities) you held on the Record Date and by the extent to which other stockholders or securities holders exercise their Basic Subscription Rights and Over-Subscription Privileges, all of which we cannot determine prior to completion of the Rights Offering. However, due to stock exchange restrictions, we will not issue Units in the Rights Offering to the extent that a holder would beneficially own, together with any other person with whom such holder’s securities may be aggregated under applicable law, more than 19.99% of our outstanding shares of common stock.

Subscription Price

The Subscription Price is $1,000 per Unit. The Subscription Price does not necessarily bear any relationship to our past or expected future results of operations, cash flows, current financial condition, or any other established criteria for value. No change will be made to the Subscription Price by reason of changes in the trading price of our common stock or other factor prior to the expiration of this Rights Offering.

Determination of Subscription Price

In the determining the Subscription Price, the board of directors considered a variety of factors including those listed below:

	●	our need to raise capital in the near term to continue our operations;

	●	the current and historical trading prices of our common stock;

	●	a price that would increase the likelihood of participation in the Rights Offering;

	●	the cost of capital from other sources;

	●	the value of the common stock being issued as a component of the Unit;

	●	the value of the Warrant being issued as a component of the Unit; and

	●	comparable precedent transactions, including the percentage of shares offered, the terms of the Subscription Rights being offered, the Subscription Price and the discount that the Subscription Price represents to the immediately prevailing closing prices for these offerings.

The Subscription Price does not necessarily bear any relationship to any established criteria for value. No valuation consultant or investment banker has opined upon the fairness or adequacy of the Subscription Price. You should not consider the Subscription Price as an indication of actual value of our company or our common stock. The market price of our common stock may decline during or after the Rights Offering. We cannot predict the price at which our shares of common stock will trade after the Rights Offering. You should obtain a current price quote for our common stock and perform an independent assessment of our Warrants before exercising your Subscription Rights and make your own assessment of our business and financial condition, our prospects for the future, and the terms of this Rights Offering. Once made, all exercises of Subscription Rights are irrevocable.

No Short-Sales

No Recombination

The Preferred Stock and Warrants comprising the Units will separate upon the exercise of the Subscription Rights, and the Units will not trade as a separate security. Holders may not recombine shares of Preferred Stock and Warrants to receive a Unit.

Non-Transferability of Subscription Rights

The Subscription Rights are non-transferable (other than by operation of law) and, therefore, you may not sell, transfer, assign or give away your Subscription Rights to anyone. The Subscription Rights will not be listed for trading on any stock exchange or market.

Expiration Date; Extension

The subscription period, during which you may exercise your Subscription Rights, expires at 5:00 p.m., Eastern Time, on February 27, 2026, which is the expiration of the Rights Offering. If you do not exercise your Subscription Rights before that time, your Subscription Rights will expire and will no longer be exercisable. We will not be required to issue shares to you if the subscription agent receives your Rights Certificate or your subscription payment after that time. We have the option to extend the Rights Offering in our sole discretion for any reason up to an additional 60 days, although we do not presently intend to do so. We may extend the Rights Offering by giving oral or written notice to the subscription agent before the Rights Offering expires. If we elect to extend the Rights Offering, we will issue a press release announcing the extension no later than 9:00 a.m., Eastern Time, on the next business day after the most recently announced expiration date of the Rights Offering.

If you hold your shares of common stock or Participating Securities in the name of a broker, dealer, bank or other nominee, the nominee will exercise the Subscription Rights on your behalf in accordance with your instructions. Please note that the nominee may establish a deadline that may be before 5:00 p.m., Eastern Time, on February 27, 2026, which is the expiration date that we have established for the Rights Offering.

Termination

We may terminate the Rights Offering at any time and for any reason prior to the expiration of the Rights Offering. If we terminate the Rights Offering, we will issue a press release notifying stockholders and the public of the termination no later than 9:00 a.m., Eastern Time, on the next business day after the most recently announced expiration date of the Rights Offering.

Return of Funds upon Completion or Termination

The subscription agent will hold funds received in payment for shares in a segregated account pending completion of the Rights Offering. The subscription agent will hold this money until the Rights Offering is completed or is terminated. To the extent you properly exercise your Over-Subscription Privilege for an amount of Units that exceeds the number of unsubscribed Units available to you, any excess subscription payments will be returned to you within 10 business days after the expiration of the Rights Offering, without interest or deduction. If the Rights Offering is terminated for any reason, all subscription payments received by the subscription agent will be returned within 10 business days, without interest or deduction.

Shares of Our Capital Stock and Warrants Outstanding After the Rights Offering

Assuming no other transactions by us involving our capital stock prior to the expiration of the Rights Offering, and if the Rights Offering is fully subscribed, upon consummation of the Rights Offering we will have 3,276,425 shares of common stock issued and outstanding, 12,000 shares of Preferred Stock issued and outstanding convertible into an aggregate of 9,996,000 shares of our common stock, and Warrants to purchase an additional 19,992,000 shares of our common stock issued and outstanding. The exact number of shares of Preferred Stock and Warrants that we will issue in this Rights Offering will depend on the number of Units that are subscribed for in the Rights Offering.

Methods for Exercising Subscription Rights

The exercise of Subscription Rights is irrevocable and may not be cancelled or modified. You may exercise your Subscription Rights as follows:

Subscription by Record Holders

If, as of the Record Date, you are a holder of record of common stock or Participating Securities, the number of Units you may purchase pursuant to your Subscription Rights is indicated on the enclosed Rights Certificate. You may exercise your Subscription Rights by properly completing and executing the Rights Certificate and forwarding it, together with your full payment, to the subscription agent at the address given below under “subscription agent,” to be received before 5:00 p.m., Eastern Time, on February 27 , 2026.

Subscription by Beneficial Owners

If as of the Record Date you are a beneficial owner of shares of our common stock or Participating Securities that are registered in the name of a broker, dealer, bank or other nominee, you will not receive a Rights Certificate. Instead, we will issue one Subscription Right to such nominee record holder for all shares of our common stock or Participating Securities held by such nominee at the Record Date. If you are not contacted by your nominee, you should promptly contact your nominee in order to subscribe for shares in the Rights Offering and follow the instructions provided by your nominee.

To properly exercise your Over-Subscription Privilege, you must deliver the subscription payment related to your Over-Subscription Privilege before the Rights Offering expires. Because we will not know the total number of unsubscribed Units before the Rights Offering expires, if you wish to maximize the number of shares you purchase pursuant to your Over-Subscription Privilege, you will need to deliver payment in an amount equal to the aggregate subscription payment for the maximum number of Units that you wish to purchase.

Payment Method

Payments must be made in full in U.S. currency by check or bank draft, or by wire transfer, and payable to “Broadridge Corporate Issuer Solutions, LLC”, as Subscription Agent for AIM ImmunoTech Inc.” You must timely pay the full subscription payment, including payment for the Over-Subscription Privilege, for the full number of shares of our common stock you wish to acquire pursuant to the exercise of Subscription Rights by delivering a:

●

Bank draft or personal check drawn against a U.S. bank payable to “Broadridge Corporate Issuer Solutions, LLC, as Subscription Agent for AIM ImmunoTech Inc.”;

●

Wire transfer of immediately available funds directly to the account maintained by Broadridge Corporate Issuer Solutions, LLC, as Subscription Agent, for purposes of accepting subscriptions in this Rights Offering at:

ABA/Routing number: 121000248

Bank: Wells Fargo

420 Montgomery Street

San Francisco, CA 94104 United States

Beneficiary Account Name: Broadridge Corporate Issuer Solutions

Account Number: 4124218686

Reference: AIM ImmunoTech Rights Offer

For Further Credit Name: AIM ImmunoTech Inc

If you elect to exercise your Subscription Rights, you should consider using a wire transfer or check drawn on a U.S. bank to ensure that the subscription agent receives your funds before the Rights Offering expires. If you send a personal check, payment will not be deemed to have been received by the subscription agent until the check has cleared. The clearinghouse may require five or more business days to clear a personal check. Accordingly, holders who wish to pay the Subscription Price by means of a personal check should make payment sufficiently in advance of the expiration of the Rights Offering to ensure that the payment is received and clears by that date. If you send a check, payment will be deemed to have been received by the subscription agent immediately upon receipt of such instrument.

You should read the instruction letter accompanying the Rights Certificate carefully and strictly follow it. DO NOT SEND RIGHTS CERTIFICATES OR PAYMENTS DIRECTLY TO US. We will not consider your subscription received until the subscription agent has received delivery of a properly completed and duly executed Rights Certificate and payment of the full subscription payment.

The method of delivery of Rights Certificates and payment of the subscription payment to the subscription agent will be at the risk of the holders of Subscription Rights. If sent by mail, we recommend that you send those certificates and payments by registered mail, properly insured, with return receipt requested, or by overnight courier, and that you allow a sufficient number of days to ensure delivery to the subscription agent and clearance of payment before the Rights Offering expires.

Missing or Incomplete Subscription Forms or Payment

If you fail to complete and sign the Rights Certificate or otherwise fail to follow the subscription procedures that apply to the exercise of your Subscription Rights before the Rights Offering expires, the subscription agent will reject your subscription or accept it to the extent of the payment received. Neither we nor our subscription agent undertakes any responsibility or action to contact you concerning an incomplete or incorrect subscription form, nor are we under any obligation to correct such forms. We have the sole discretion to determine whether a subscription exercise properly complies with the subscription procedures.

If you send a payment that is insufficient to purchase the number of shares you requested, or if the number of shares you requested is not specified in the forms, the payment received will be applied to exercise your Subscription Rights to the fullest extent possible based on the amount of the payment received. Any excess subscription payments received by the subscription agent will be returned, without interest or deduction, within 10 business days following the expiration of the Rights Offering.

Issuance of Preferred Stock and Warrants

The shares of Preferred Stock and Warrants that are purchased in the Rights Offering as part of the Units will be issued in book-entry, or uncertificated, form meaning that you will receive a DRS account statement from our transfer agent as it relates to the Preferred Stock and warrant agent as it relates to the Warrants reflecting ownership of these securities if you are a holder of record. If you hold your shares of common stock or Participating Securities in the name of a bank, broker, dealer, or other nominee, DTC will credit your account with your nominee with the securities you purchased in the Rights Offering.

Subscription and Information Agent

The subscription agent for the Rights Offering is Broadridge Corporate Issuer Solutions, LLC, and the information agent also is Broadridge Corporate Issuer Solutions, LLC. The address to which Rights Certificates and payments should be mailed or delivered by overnight courier is provided below. If sent by mail, we recommend that you send documents and payments by registered mail, properly insured, with return receipt requested, and that you allow a sufficient number of days to ensure delivery to the subscription agent and clearance or payment before the Rights Offering expires. Do not send or deliver these materials to us.

Warrant Agent

The warrant agent for the Warrants is EQ.

No Fractional Shares

We will not issue fractional shares of common stock in the Rights Offering. We will only distribute Subscription Rights to acquire whole Units, rounded down to the nearest whole number of underlying shares of common stock giving rise to such Subscription Rights. Any excess subscription payments received by the subscription agent will be returned within 10 business days after expiration of the Rights Offering, without interest or deduction. Similarly, no fractional shares of common stock will be issued in connection with the conversion of the Preferred Stock or the exercise of a Warrant. Instead, for any such fractional share that would otherwise have been issuable upon conversion of shares of Preferred Stock, we may, at our election, pay a cash payment equal to such fraction multiplied by the conversion price or round up to the next whole share, and for any such fractional share that would have otherwise been issued upon exercise of Warrants, we will round up such fraction to the next whole share.

Notice to Brokers and Nominees

If you are a broker, dealer, bank or other nominee holder that holds shares of our common stock or Participating Securities for the account of others on the Record Date, you should notify the beneficial owners for whom you are the nominee of the Rights Offering as soon as possible to learn their intentions with respect to exercising their Subscription Rights. If a beneficial owner of our common stock or Participating Securities so instructs, you should complete the Rights Certificate and submit it to the subscription agent with the proper subscription payment by the expiration date. You may exercise the number of Subscription Rights to which all beneficial owners in the aggregate otherwise would have been entitled had they been direct holders of our common stock on the Record Date, provided that you, as a nominee record holder, make a proper showing to the subscription agent by submitting the form entitled “Nominee Holder Certification,” which is provided with your Rights Offering materials. If you did not receive this form, you should contact our subscription agent to request a copy.

Validity of Subscriptions

We will resolve all questions regarding the validity and form of the exercise of your Subscription Rights, including time of receipt and eligibility to participate in the Rights Offering. Our determination will be final and binding. Once made, subscriptions are irrevocable; we will not accept any alternative, conditional, or contingent subscriptions. We reserve the absolute right to reject any subscriptions not properly submitted or the acceptance of which would be unlawful. You must resolve any irregularities in connection with your subscriptions before the expiration date of the Rights Offering, unless we waive them in our sole discretion. Neither we nor the subscription agent is under any duty to notify you or your representative of defects in your subscriptions. A subscription will be considered accepted, subject to our right to withdraw or terminate the Rights Offering, only when the subscription agent receives a properly completed and duly executed Rights Certificate and any other required documents and the full subscription payment including final clearance of any personal check. Our interpretations of the terms and conditions of the Rights Offering will be final and binding.

Stockholder Rights

You will have no rights as a holder of the shares of our common stock issuable upon conversion of the Preferred Stock issued in the Rights Offering until such Preferred Stock is converted into common stock and issued in book-entry form or your account at your broker, dealer, bank or other nominee is credited with the shares of our common stock. Holders of Warrants issued in connection with the Rights Offering will not have rights as holders of our common stock until such Warrants are exercised and the shares of common stock underlying the Warrants are issued to the holder.

Foreign Stockholders

We will not mail this prospectus or Rights Certificates to stockholders with addresses that are outside the United States or that have an army post office or foreign post office address. The subscription agent will hold these Rights Certificates for their account. To exercise Subscription Rights, our foreign stockholders must notify the subscription agent prior to 5:00 p.m., Eastern Time, on February 24, 2026, the third business day prior to the expiration date, of your exercise of Subscription Rights and provide evidence satisfactory to us, such as a legal opinion from local counsel, that the exercise of such Subscription Rights does not violate the laws of the jurisdiction in which such stockholder resides and payment by a U.S. bank in U.S. dollars before the expiration of the offer. If no notice is received by such time or the evidence presented is not satisfactory to us, the Subscription Rights represented thereby will expire.

No Revocation or Change

Once you submit the Rights Certificate or have instructed your nominee of your subscription request, you are not allowed to revoke or change the exercise or request a refund of monies paid. All exercises of Subscription Rights are irrevocable, even if you learn information about us that you consider to be unfavorable. You should not exercise your Subscription Rights unless you are certain that you wish to purchase shares at the Subscription Price. If we should make any fundamental changes to the terms set forth in this prospectus, we will (i) file a post-effective amendment to the registration statement of which this prospectus forms a part, (ii) offer potential purchasers who have subscribed for rights the opportunity to cancel such subscriptions, and (iii) issue a refund of any money advanced by such stockholder or eligible warrant holder and recirculate an updated prospectus after the post-effective amendment is declared effective with the SEC.

U.S. Federal Income Tax Treatment of Rights Distribution

For U.S. federal income tax purposes, we do not believe holders of shares of our common stock or Participating Securities should recognize income or loss upon receipt or exercise of a Subscription Right, but the receipt and exercise of the Subscription Rights is unclear in certain respects. See “Material U.S. Federal Income Tax Consequences.”

No Recommendation to Rights Holders

Our board of directors is not making a recommendation regarding your exercise of the Subscription Rights. Stockholders who exercise Subscription Rights risk investment loss on money invested. We cannot predict the price at which our shares of common stock or Warrants will trade after the Rights Offering. You should make your investment decision based on your assessment of our business and financial condition, our prospects for the future and the terms of this Rights Offering. Please see “Risk Factors” for a discussion of some of the risks involved in investing in our common stock.

Fees and Expenses

We will pay all fees charged by the subscription agent and the information agent, and by the dealer-manager. You are responsible for paying any other commissions, fees, taxes or other expenses incurred in connection with the exercise of your Subscription Rights.

Listing

The Subscription Rights may not be sold, transferred, assigned or given away to anyone, and will not be listed for trading on any stock exchange or market. There is no public trading market for the Preferred Stock or the Warrants. We do not intend to apply for listing of the Preferred Stock or the Warrants on any securities exchange or recognized trading system. The shares of our common stock issuable upon the conversion of the Preferred Stock and the exercise of the Warrants to be issued in the Rights Offering are traded on the NYSE American under the symbol “AIM.”

Important

Do not send Rights Certificates directly to us. You are responsible for choosing the payment and delivery method for your Rights Certificate and you bear the risks associated with such delivery. If you choose to deliver your Rights Certificate and payment by mail, we recommend that you use registered mail, properly insured, with return receipt requested. We also recommend that you allow a sufficient number of days to ensure delivery to the subscription agent and clearance of payment prior to the expiration time.

Distribution Arrangements

Maxim Group LLC will act as dealer-manager for the Rights Offering. The dealer-manager will provide marketing assistance and advice to us in connection with the Rights Offering and will use its best efforts to solicit the exercise of Subscription Rights and participation in the Over-Subscription Privilege. The dealer-manager is not underwriting or placing any of the Subscription Rights or the shares of our Preferred Stock or Warrants to be issued in the Rights Offering and does not make any recommendation with respect to such Subscription Rights (including with respect to the exercise or expiration of such Subscription Rights), shares of Preferred Stock or Warrants. We have agreed to pay the dealer-manager certain fees and to reimburse the dealer-manager for certain out-of-pocket expenses incurred in connection with this Rights Offering. See “Plan of Distribution.”

Other Matters

We are not making the Rights Offering in any state or other jurisdiction in which it is unlawful to do so, nor are we distributing or accepting any offers to purchase any Units from Subscription Rights holders who are residents of those states or other jurisdictions or who are otherwise prohibited by federal or state laws or regulations from accepting or exercising the Subscription Rights. We may delay the commencement of the Rights Offering in those states or other jurisdictions, or change the terms of the Rights Offering, in whole or in part, in order to comply with the securities laws or other legal requirements of those states or other jurisdictions. Subject to state securities laws and regulations, we also have the discretion to delay allocation and distribution of any securities you may elect to purchase by exercise of your subscription privileges in order to comply with state securities laws. We may decline to make modifications to the terms of the Rights Offering requested by those states or other jurisdictions, in which case, if you are a resident in those states or jurisdictions or if you are otherwise prohibited by federal or state laws or regulations from accepting or exercising the Subscription Rights, you will not be eligible to participate in the Rights Offering. However, we are not currently aware of any states or jurisdictions that would preclude participation in the Rights Offering.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following discussion describes the material U.S. federal income tax consequences of the receipt and exercise (or expiration) of the Subscription Rights acquired through the Rights Offering, the ownership and disposition of shares of our Preferred Stock and Warrants received upon exercise of the Subscription Rights and the ownership and disposition of the shares of common stock received upon the conversion of our Preferred Stock or the exercise of the Warrants. This discussion does not purport to be a complete analysis of all potential tax consequences. The effects of other U.S. federal tax laws, such as estate and gift tax laws, alternative minimum tax laws, net investment tax laws, and any applicable state, local or non-U.S. tax laws are not discussed. This discussion is based on the Code, U.S. Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of IRS in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a holder of the Subscription Rights, shares of our Preferred Stock, Warrants or shares of our common stock. This summary does not discuss the potential effects, whether adverse or beneficial, of any proposed legislation that, if enacted, could be applied on a retroactive or prospective basis. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance the IRS or a court will not take a contrary position to that discussed below regarding the tax consequences of the receipt of Subscription Rights through the Rights Offering by persons holding shares of our common stock and Participating Securities pursuant to this Rights Offering, the exercise (or expiration) of the Subscription Rights, the acquisition, ownership and disposition of shares of our Preferred Stock, and the acquisition, ownership and disposition (or expiration) of Warrants, each acquired upon exercise of the Subscription Rights, and the acquisition, ownership and disposition of shares of our common stock acquired upon conversion of our Preferred Stock or exercise of the Warrants.

This discussion is limited to the Subscription Rights acquired through the Rights Offering, shares of our Preferred Stock and Warrants acquired upon exercise of Subscription Rights and shares of our common stock acquired upon conversion of our Preferred Stock or exercise of the Warrants, in each case, that are held as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all U.S. federal income tax consequences relevant to a holder’s particular circumstances, including the impact of the alternative minimum tax or the unearned income Medicare contribution tax. In addition, it does not address consequences relevant to holders subject to particular rules, including, without limitation:

	●	U.S. expatriates and former citizens or long-term residents of the United States;

	●	U.S. holders (as defined below) that are subject to taxing jurisdictions other than, or in addition to, the United States or otherwise hold shares of our common stock, the Subscription Rights, shares of our Preferred Stock or Warrants in connection with a trade or business, permanent establishment, or fixed base outside the United States;

	●	corporations organized outside the United States, any state thereof, or the District of Columbia that are nonetheless treated as U.S. persons for U.S. federal income tax purposes;

	●	persons holding shares of our common stock, the Subscription Rights, shares of our Preferred Stock or Warrants as part of a hedge, straddle or other risk reduction strategy or as part of a conversion transaction or other integrated investment;

	●	banks, insurance companies, underwriters, and other financial institutions;

	●	brokers, dealers or traders in securities or currencies or traders that elect to mark-to-market their securities;

	●	“controlled foreign corporations,” “passive foreign investment companies,” and corporations that accumulate earnings to avoid U.S. federal income tax;

	●	partnerships or other entities or arrangements treated as partnerships or other pass-through entities for U.S. federal income tax purposes (and investors therein) and S corporations (and shareholders thereof);

	●	real estate investment trusts, regulated investment companies, grantor trusts, tax-exempt organizations or governmental organizations;

	●	persons deemed to sell the Subscription Rights, shares of Preferred Stock, or Warrants or shares of our common stock under the constructive sale provisions of the Code;

	●	persons subject to special tax accounting rules as a result of any item of gross income being taken into account in an applicable financial statement (as defined in the Code);

	●	persons for whom our stock constitutes “qualified small business stock” within the meaning of Section 1202 of the Code;

	●	persons who received, hold or will receive shares of our common stock, Participating Securities, the Subscription Rights, shares of our Preferred Stock or Warrants pursuant to the exercise of any employee stock option or otherwise as compensation and persons who hold restricted common stock;

	●	tax-qualified retirement plans, individual retirement accounts, or other tax-deferred accounts;

	●	persons subject to the alternative minimum tax; and

	●	U.S. holders that have a functional currency other than the U.S. dollar.

If an entity treated as a partnership for U.S. federal income tax purposes holds shares of our common stock, the Subscription Rights, shares of our Preferred Stock and Warrants acquired upon exercise of Subscription Rights or shares of our common stock acquired upon conversion of our Preferred Stock or exercise of the Warrants, as the case may be, the tax treatment of a partner in the partnership will depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, partnerships and the partners in such partnerships should consult their own tax advisors regarding the U.S. federal income tax consequences to them.

THIS DISCUSSION IS FOR INFORMATION PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE RECEIPT, OWNERSHIP AND EXERCISE OF SUBSCRIPTION RIGHTS, THE ACQUISITION, OWNERSHIP, AND DISPOSITION OF SHARES OF OUR PREFERRED STOCK AND WARRANTS ACQUIRED UPON EXERCISE OF SUBSCRIPTION RIGHTS, AND SHARES OF OUR COMMON STOCK ACQUIRED UPON CONVERSION OF PREFERRED STOCK OR EXERCISE OF WARRANTS ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Tax Considerations Applicable to U.S. Holders

Definition of a U.S. Holder

For purposes of this discussion, a “U.S. holder” is any beneficial owner of shares of our common stock, our Subscription Rights, shares of our Preferred Stock and Warrants acquired upon exercise of Subscription Rights or shares of our common stock acquired upon conversion of our Preferred Stock or exercise of Warrants, as the case may be, that, for U.S. federal income tax purposes, is:

	●	an individual who is a citizen or resident of the United States;

	●	a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States, any state thereof, or the District of Columbia;

	●	an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

	●	a trust that (1) is subject to the primary supervision of a U.S. court and the control of one or more United States persons (within the meaning of Section 7701(a)(30) of the Code), or (2) has made a valid election under applicable U.S. Treasury Regulations to continue to be treated as a United States person.

Receipt of Subscription Rights

Although the authorities governing transactions such as this Rights Offering are complex and do not speak directly to the consequences of certain aspects of this Rights Offering, including the inclusion of the right to purchase Warrants in the Subscription Rights (rather than the right to purchase only shares of our Preferred Stock), the distribution of Subscription Rights to holders of Participating Securities and the effects of the Over-Subscription Privilege, we do not believe a U.S. holder’s receipt of Subscription Rights pursuant to the Rights Offering should be treated as a taxable distribution with respect to its existing shares of common stock or Participating Securities, as applicable, for U.S. federal income tax purposes. Section 305(a) of the Code generally provides that the receipt by a stockholder, or a holder of rights to acquire stock, of a right to acquire stock or warrants is not included in the taxable income of the stockholder; however, the general non-recognition rule in Section 305(a) of the Code is subject to exceptions described in Section 305(b) of the Code, which include “disproportionate distributions.” A disproportionate distribution is generally a distribution or a series of distributions, including deemed distributions, that has the effect of the receipt of cash or other property by some stockholders (including holders of rights to acquire stock and holders of debt instruments convertible into stock) and an increase in the proportionate interest of other stockholders (including holders of rights to acquire stock and holders of debt instruments convertible into stock) in a corporation’s assets or earnings and profits. During the last 36 months, we have not made any distributions of cash or property (other than stock or rights to acquire stock) with respect to: (i) our common stock or (ii) options or warrants to acquire our common stock. Currently we do not intend to make any future distributions of cash or property (other than stock or rights to acquire stock) with respect to: (i) our common stock or (ii) options or warrants to acquire our common stock; however, there is no guarantee that we will not make such distributions in the future. In addition, we do not currently have any convertible debt outstanding nor do we currently intend to issue any convertible debt.

The position regarding the non-taxable treatment of the Subscription Right distribution is not binding on the IRS, or the courts. If this position is finally determined by the IRS or a court to be incorrect, whether because, contrary to our expectations, distributions of cash or property (other than stock or rights to acquire stock) are made with respect to our common stock, options or warrants, because the issuance of the Subscription Rights is a “disproportionate distribution” or otherwise, the fair market value of the Subscription Rights would be taxable to U.S. holders of our common stock as a dividend to the extent of the U.S. holder’s pro rata share of our current and accumulated earnings and profits, if any, with any excess being treated as a return of capital to the extent thereof and then as capital gain. Although no assurance can be given, we anticipate that we will not have current and accumulated earnings and profits through the end of 2025. Further, if the position regarding the non-taxable treatment of the Subscription Rights distribution is incorrect, the treatment of holders of Participating Securities is not clear, and it may differ from, and may be more adverse than, the treatment of the Subscription Rights distribution to the holders of common stock.

The following discussion is based upon the treatment of the Subscription Right issuance as a non-taxable distribution with respect to a U.S. holder’s’ existing shares of common stock or Participating Securities for U.S. federal income tax purposes.

Tax Basis in the Subscription Rights

If the fair market value of the Subscription Rights a U.S. holder receives is less than 15% of the fair market value of the U.S. holder’s existing shares of common stock or Participating Securities (in each case, with respect to which the Subscription Rights are distributed) on the date the U.S. holder receives the Subscription Rights, the Subscription Rights will be allocated a zero tax basis for U.S. federal income tax purposes, unless the U.S. holder elects to allocate the tax basis in the holder’s existing shares of common stock or Participating Securities between the existing shares of common stock or Participating Securities and the Subscription Rights in proportion to the relative fair market values of the existing shares of common stock or Participating Securities and the Subscription Rights determined on the date of receipt of the Subscription Rights. If a U.S. holder chooses to allocate tax basis between the holder’s existing common stock or Participating Securities and the Subscription Rights, the U.S. holder must make this election on a statement included with the holder’s timely filed U.S. federal income tax return (including extensions) for the taxable year in which the U.S. holder receives the Subscription Rights. Such an election is irrevocable.

However, if the fair market value of the Subscription Rights a U.S. holder receives is 15% or more of the fair market value of the holder’s existing shares of common stock or Participating Securities on the date the U.S. holder receives the Subscription Rights, then the U.S. holder must allocate tax basis in the existing shares of common stock or Participating Securities between those shares or warrants and the Subscription Rights the U.S. holder receives in proportion to their fair market values determined on the date the U.S. holder receives the Subscription Rights. Please refer to the discussion below regarding the U.S. tax treatment of a U.S. holder that, at the time of the receipt of the Subscription Right, no longer holds the common stock or Participating Securities with respect to which the Subscription Right was distributed.

The fair market value of the Subscription Rights on the date that the Subscription Rights are distributed is uncertain and the fair market value of the Participating Securities is uncertain, and we have not obtained, and do not intend to obtain, an appraisal of the fair market value of the Subscription Rights or the Participating Securities on that date. In determining the fair market value of the Subscription Rights, U.S. holders should consider all relevant facts and circumstances, including without limitation any difference between the Subscription Price of the Subscription Rights and the trading price of our shares of common stock on the date that the Subscription Rights are distributed, the fair market value and the conversion terms of the Preferred Stock, the exercise price of the Warrants, the length of the period during which the Subscription Rights may be exercised and the fact that the Subscription Rights are non-transferable. In determining the fair market value of the Participating Securities, U.S. holders should consider all relevant facts and circumstances, including without limitation the difference between the exercise price of the Participating Securities and the trading price of our common stock on the date that the Subscription Rights are distributed, the length of the period during which the Participating Securities may be exercised, the nature of the adjustment provisions in the Participating Securities that may affect the economics of the exercise of such Participating Securities and any limitations of the transferability of the Participating Securities.

Exercise of Subscription Rights

A U.S. holder will not recognize gain or loss upon the exercise of a Subscription Right received in the Rights Offering. A U.S. holder’s adjusted tax basis, if any, in the Subscription Right plus the Subscription Price should be allocated between the share of Preferred Stock and the Warrants acquired upon exercise of the Subscription Right. We believe that the tax basis in the common stock or Participating Securities upon which the Subscription Rights were issued which is allocated to the Subscription Rights under the prior section entitled “—Tax Basis in the Subscription Rights” should be further allocated between the shares of Preferred Stock and the Warrants acquired upon exercise of the Subscription Right in proportion to their relative fair market values on the date the Subscription Rights were distributed. The Subscription Price should be allocated between the shares of Preferred Stock and the Warrant acquired upon exercise of the Subscription Right in proportion to their relative fair market values on the exercise date. These allocations will establish the U.S. holder’s initial tax basis for U.S. federal income tax purposes in the shares of Preferred Stock and Warrants received upon exercise of such U.S. holder’s Subscription Right. The holding period of a share of Preferred Stock or a Warrant acquired upon exercise of a Subscription Right in the Rights Offering will begin on the date of exercise.

If, at the time of the receipt or exercise of the Subscription Right, the U.S. holder no longer holds the common stock or Participating Securities with respect to which the Subscription Right was distributed, then certain aspects of the tax treatment of the receipt and exercise of the Subscription Right are unclear, including (1) the allocation of the tax basis between the shares of our common stock or Participating Securities previously sold and the Subscription Right, (2) the impact of such allocation on the amount and timing of gain or loss recognized with respect to the shares of our common stock or Participating Securities previously sold, and (3) the impact of such allocation on the tax basis of the shares of our Preferred Stock and Warrants acquired upon exercise of the Subscription Right. If a U.S. holder exercises a Subscription Right received in the Rights Offering after disposing of shares of our common stock or Participating Securities with respect to which the Subscription Right is received, the U.S. holder should consult its own tax advisor.

Expiration of Subscription Rights

If a U.S. holder allows Subscription Rights received in the Rights Offering to expire, the U.S. holder should not recognize any gain or loss for U.S. federal income tax purposes, and the U.S. holder should re-allocate any portion of the tax basis in its existing common stock or participating warrants or options previously allocated to the Subscription Rights that have expired to such U.S. holder’s existing common stock or participating options or warrants, as applicable.

Sale or Other Disposition, Exercise or Expiration of Warrants

Upon the sale or other taxable disposition of a Warrant (other than by exercise) received upon exercise of a Subscription Right, a U.S. holder will generally recognize capital gain or loss equal to the difference between the amount realized on the sale or other taxable disposition and the U.S. holder’s adjusted tax basis in the Warrant. A U.S. Holder’s adjusted tax basis in a Warrant will generally equal its initial tax basis (discussed above under “—Exercise of Subscription Rights”), as adjusted for any constructive dividends on the Warrant described below. This capital gain or loss will be long-term capital gain or loss if the U.S. holder’s holding period in such Warrant is more than one year at the time of the sale or other taxable disposition. The deductibility of capital losses is subject to certain limitations.

A U.S. holder will not be required to recognize income, gain or loss upon exercise of a Warrant received upon exercise of a Subscription Right. A U.S. holder’s tax basis in a share of our common stock received upon exercise of the Warrants for cash will be equal to the sum of (1) the U.S. holder’s tax basis in the Warrants exchanged therefor and (2) the exercise price of such Warrants. A U.S. holder’s holding period in the shares of our common stock received upon exercise will commence on the day after such U.S. holder exercises the Warrants.

In certain circumstances, the Warrants will be exercisable on a cashless basis. The U.S. federal income tax treatment of an exercise of a Warrant on a cashless basis is not clear, and could differ from the consequences described above. It is possible that a cashless exercise could be a taxable event. U.S. holders are urged to consult their own tax advisors as to the consequences of an exercise of a Warrant on a cashless basis, including with respect to whether the exercise is a taxable event, and their holding period and tax basis in the common stock received.

If a Warrant expires without being exercised, a U.S. holder will recognize a capital loss in an amount equal to such holder’s adjusted tax basis in the Warrant. Such loss will be long-term capital loss if, at the time of the expiration, the U.S. holder’s holding period in such Warrant is more than one year. The deductibility of capital losses is subject to certain limitations.

Constructive Dividends on Warrants

As described in the section entitled “Dividend Policy,” we do not anticipate declaring or paying dividends to holders of our common stock or our Preferred Stock in the foreseeable future. However, if at any time during the period in which a U.S. holder holds Warrants received upon exercise of a Subscription Right, we were to pay a taxable dividend to our stockholders and, in accordance with the anti-dilution provisions of the Warrants, the exercise price of the Warrants were decreased, that decrease would be deemed to be the payment of a taxable dividend to a U.S. holder of the Warrants to the extent of our earnings and profits, notwithstanding the fact that such holder will not receive a cash payment. If the exercise price is adjusted in certain other circumstances (or in certain circumstances, there is a failure to make appropriate adjustments), or there is an adjustment to the number of shares of common stock that will be issued on exercise of the Warrants, such adjustments may also result in the deemed payment of a taxable dividend to a U.S. holder. U.S. holders should consult their own tax advisors regarding the proper treatment of any adjustments to the exercise price of the Warrants. We are currently required to report the amount of any deemed distributions to the IRS, as well as either on our website or to holders not exempt from reporting.

Distributions on Preferred Stock and Common Stock

As described in the section entitled “Dividend Policy,” we do not anticipate declaring or paying dividends to holders of our Preferred Stock or common stock in the foreseeable future. However, if we do make distributions of cash or property on our Preferred Stock or common stock, such distributions will constitute dividends to the extent paid out of our current or accumulated earnings and profits, as determined for U.S. federal income tax purposes. Dividends received by a corporate U.S. holder may be eligible for a dividends received deduction, subject to applicable limitations. Dividends received by certain non-corporate U.S. holders, including individuals, are generally taxed at the lower applicable capital gains rate provided certain holding period and other requirements are satisfied. Distributions in excess of our current and accumulated earnings and profits will constitute a return of capital and first be applied against and reduce a U.S. holder’s adjusted tax basis in its Preferred Stock or common stock, as the case may be, but not below zero. Any excess will be treated as capital gain and will be treated as described below in the section relating to the sale or disposition of our common stock.

Sale, Exchange or Other Disposition of Preferred Stock and Common Stock

Upon a sale, exchange, or other taxable disposition of our Preferred Stock (other than by conversion) or our common stock, a U.S. holder generally will recognize capital gain or loss equal to the difference between the amount realized (not including any amount attributable to declared and unpaid dividends, which will be taxable as described above to U.S. holders of record who have not previously included such dividends in income) and the U.S. holder’s adjusted tax basis in our Preferred Stock or our common stock. The U.S. holder’s adjusted tax basis in our Preferred Stock generally will equal its initial tax basis (discussed above under “—Exercise of Subscription Rights”), as adjusted for applicable distributions (including constructive dividends described below). A U.S. holder’s adjusted tax basis in our common stock generally will equal its initial tax basis in our common stock (discussed below under “—Conversion of the Preferred Stock into Our Common Stock”), as adjusted for applicable distributions (including constructive dividends described below). Such capital gain or loss generally will be long-term capital gain or loss if the U.S. holder’s holding period for our Preferred Stock or our common stock exceeded one year at the time of disposition (see the discussion below under “—Conversion of Our Preferred Stock into Our Common Stock” regarding a U.S. holder’s holding period for our common stock). Long-term capital gains recognized by certain non-corporate U.S. holders, including individuals, generally are subject to reduced rates of taxation. The deductibility of capital losses is subject to limitations.

Conversion of Our Preferred Stock into Our Common Stock

A U.S. holder will not recognize any gain or loss in respect of the receipt of our common stock upon the conversion of our Preferred Stock (except to the extent the U.S. holder receives a cash payment for any fractional share that would otherwise have been issuable upon conversion of the Preferred Stock). The adjusted tax basis of our common stock that a U.S. holder receives on conversion will equal the adjusted tax basis of the Preferred Stock converted (decreased by the adjusted tax basis allocable to any fractional share that would otherwise have been issued upon conversion of the Preferred Stock), and the holding period of such common stock received on conversion will include the period during which the U.S. holder held the Preferred Stock prior to conversion.

In the event a U.S. holder’s Preferred Stock is converted pursuant to an election by such U.S. holder in the case of certain acquisitions or fundamental changes or pursuant to certain other transactions (including our consolidation or merger into another person), the tax treatment of such a conversion will depend upon the facts underlying the particular transaction triggering such a conversion. In this regard, it is possible that any related adjustments of the conversion rate would be treated as a constructive distribution to the U.S. holder as described below under “—Constructive Dividends on Preferred Stock.” U.S. holders should consult their own tax advisors to determine the specific tax treatment of a conversion under such circumstances.

Constructive Dividends on Preferred Stock or Common Stock

The conversion rate of our Preferred Stock is subject to adjustment under certain circumstances, as described below under “Description of Securities—Preferred Stock—Preferred Stock.” Section 305(c) of the Code and U.S. Treasury Regulations thereunder may treat a U.S. holder of our Preferred Stock as having received a constructive distribution includable in such U.S. holder’s income in the manner as described above under “—Distributions on Preferred Stock and Common Stock,” if and to the extent that certain adjustments in the conversion rate (or failures to make such an adjustment) increase the proportionate interest of such U.S. holder in our earnings and profits. In certain other circumstances, an adjustment to the conversion rate of our Preferred Stock or a failure to make such an adjustment could potentially give rise to constructive distributions to U.S. holders of our common stock. Thus, under certain circumstances, U.S. holders may recognize income in the event of a constructive distribution even though they may not receive any cash or property. We are currently required to report the amount of any deemed distributions to the IRS, as well as either on our website or to holders not exempt from reporting.

Information Reporting and Backup Withholding

A U.S. holder may be subject to information reporting and backup withholding when such holder receives dividend payments (including constructive dividends) or receives proceeds from the sale or other taxable disposition of the Warrants, shares of our Preferred Stock acquired through the exercise of Subscription Rights or shares of our common stock acquired through conversion of our Preferred Stock or exercise of the Warrants. Certain U.S. holders are exempt from backup withholding, including certain corporations and certain tax-exempt organizations. A U.S. holder will be subject to backup withholding if such holder is not otherwise exempt (or fails to properly establish an exemption) and such holder:

●

fails to furnish the holder’s taxpayer identification number, which for an individual is ordinarily his or her social security number;

	●	furnishes an incorrect taxpayer identification number;

	●	is notified by the IRS that the holder previously failed to properly report payments of interest or dividends; or

	●	fails to certify under penalties of perjury that the holder has furnished a correct taxpayer identification number and that the IRS has not notified the holder that the holder is subject to backup withholding.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a U.S. holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS. U.S. holders should consult their own tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption.

Tax Considerations Applicable to Non-U.S. Holders

For purposes of this discussion, a “non-U.S. holder” is a beneficial owner of shares of our common stock, Participating Securities, our Subscription Rights, shares of our Preferred Stock and Warrants acquired upon exercise of Subscription Rights or shares of our common stock acquired upon conversion of our Preferred Stock or exercise of Warrants, as the case may be, that is neither a U.S. holder nor an entity treated as a partnership for U.S. federal income tax purposes.

Receipt, Exercise and Expiration of the Subscription Rights

The discussion assumes that the receipt of Subscription Rights will be treated as a nontaxable distribution. See “—Tax Considerations Applicable to U.S. Holders—Receipt of Subscription Rights” above. In such case, non-U.S. holders will not be subject to U.S. federal income tax (or any withholding thereof) on the receipt, exercise or expiration of the Subscription Rights.

Exercise of Warrants

A non-U.S. holder will not be subject to U.S. federal income tax on the cash exercise of Warrants into shares of our common stock. As discussed above in “—Tax Considerations Applicable to U.S. Holders—Sale or Other Disposition, Exercise or Expiration of Warrants,” the U.S. federal income tax treatment of an exercise of a Warrant on a cashless basis is not clear. Non-U.S. holders are urged to consult their own tax advisors as to the consequences of an exercise of a Warrant on a cashless basis, including with respect to whether the exercise is a taxable event, and their holding period and tax basis in the common stock received.
