Filed Pursuant to 424(b)(5)

File No. 333-277585

GeoVax Labs, Inc.

Up to $4,486,846

Common Stock

We have entered into a Sales Agreement (the "Sales Agreement") with A.G.P./Alliance Global Partners ("A.G.P.") as agent, relating to the sale of shares of our common stock, par value $0.001 per share (our "common stock"), offered by this prospectus supplement and the accompanying prospectus. In accordance with the terms of the Sales Agreement, under this prospectus supplement and the accompanying prospectus, we may offer and sell shares of our common stock having an aggregate offering price of up to $4,486,846 from time to time through or to A.G.P., as sales agent or principal.

Our common stock is quoted on The Nasdaq Capital Market (the "Nasdaq") under the symbol "GOVX." On September 20, 2024, the last reported sale price of our common stock was $2.95 per share.

Sales of our common stock, if any, under this prospectus supplement and the accompanying prospectus may be made by any method permitted that is deemed to be an "at the market offering" as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended (the "Securities Act"). If we and A.G.P. agree on a method of distribution other than sales of shares of our common stock on or through Nasdaq or another existing trading market at market prices, we will file a further prospectus supplement providing all information about such offering as required by Rule 424(b) under the Securities Act.

A.G.P. is not required to sell any specific number or dollar amount of securities, but will act as our sales agent using commercially reasonable efforts to sell on our behalf all of the shares of common stock requested to be sold by us, consistent with its normal trading and sales practices, on mutually agreed terms between A.G.P. and us. There is no arrangement for funds to be received in any escrow, trust or similar arrangement.

The compensation to A.G.P. for sales of common stock sold pursuant to the Sales Agreement will be an amount equal to 3.0% of the aggregate gross proceeds of any shares of common stock sold under the Sales Agreement. In connection with the sale of the common stock on our behalf, A.G.P. will be deemed to be an "underwriter" within the meaning of the Securities Act and the compensation of A.G.P. will be deemed to be underwriting commissions or discounts. We have also agreed to provide indemnification and contribution to A.G.P. with respect to certain civil liabilities, including liabilities under the Securities Act or the Securities Exchange Act of 1934, as amended (the "Exchange Act").

In no event will we sell, pursuant to the registration statement of which this prospectus supplement and the accompanying prospectus forms a part, more shares of common stock than we have available and authorized for issuance.

As of September 25, 2024, the aggregate market value of our outstanding common stock held by non-affiliates was approximately $70,808,159, which was calculated based on 8,480,019 shares of outstanding common stock held by non-affiliates, at a price per share of $8.35, the closing price of our common stock on August 21, 2024, the highest closing price of the Company's common stock on the Nasdaq Capital Market during the preceding sixty (60) day trading period. Pursuant to General Instruction I.B.6 of Form S-3, in no event will we sell the securities described in this prospectus supplement in a public primary offering with a value exceeding more than one-third (1/3) of the aggregate market value of our common stock held by non-affiliates in any twelve (12)-month period, so long as the aggregate market value of our outstanding common stock held by non-affiliates remains below $75,000,000. During the twelve (12) calendar months prior to and including the date of this prospectus supplement, we have offered and sold aggregate gross proceeds of approximately $19,115,874 of our securities pursuant to General Instruction I.B.6 of Form S-3.

Investing in our common stock involves significant risks. See "Risk Factors" beginning on page S-11 of this prospectus supplement, page 7 of the accompanying prospectus and under similar headings in the documents incorporated by reference into this prospectus supplement and the accompanying prospectus.

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

A.G.P.

The date of this prospectus supplement is September 25, 2024.

S-3

Our programs are in various stages of development, the most significant of which are summarized below along with recent developments. We have not generated any revenues from the sale of the products we are developing, and we do not expect to generate any such revenues for at least the next several years. Our product candidates will require significant additional research and development efforts, including extensive preclinical and clinical testing. All product candidates that we advance to clinical testing will require regulatory approval prior to commercial use and will require significant costs for commercialization. We may not be successful in our research and development efforts, and we may never generate sufficient product revenue to be profitable.

Strategy

Our corporate strategy is to advance, protect and exploit our differentiated vaccine and oncology platforms leading to the successful development of preventive and therapeutic interventions against infectious diseases and various cancers. With our design and development capabilities, we are progressing and validating an array of cancer treatment and infectious disease vaccine product candidates. Our goal is to advance products through to human clinical testing, registration and commercialization in the U.S, and to seek partnership or licensing arrangements for achieving regulatory approval and commercialization outside of the U.S. We also leverage third party resources through collaborations and partnerships for preclinical and clinical testing with multiple government, academic and corporate entities.

Recent Development - BARDA Project NextGen Award - GEO-CM04S1 Phase 2b Trial

On June 18, 2024, we announced our receipt of an award through the Rapid Response Partnership Vehicle (RRPV) to advance development of GEO-CM04S1, our dual-antigen next-generation COVID-19 vaccine, in a Phase 2b clinical trial Under the agreement, GeoVax will sponsor a 10,000-participant, randomized, Phase 2b double-blinded study to assess the clinical efficacy, safety, and immunogenicity of GEO-CM04S1 compared with a U.S. Food and Drug Administration (FDA)-approved mRNA COVID-19 vaccine. The RRPV is a Consortium funded by the Biomedical Advanced Research and Development Authority (BARDA), part of the Administration for Strategic Preparedness and Response (ASPR) in the U.S. Department of Health and Human Services (HHS).

Preparations for the Phase 2b study are underway, and execution of the study will be fully funded by BARDA under its Clinical Studies Network. The direct award to GeoVax of $24.3 million, which may increase to as much as $45 million, will fund the manufacturing of clinical materials and support for the Phase 2b clinical trial, including regulatory activities. BARDA has made a separate award of $343 million from the Project NextGen program to Allucent, a global clinical research organization (CRO), to execute the clinical trial as part of BARDA's Clinical Studies Network. The combined value of the awards to GeoVax and Allucent toward the clinical evaluation of GEO-CM04S1 is expected to be $367-388 million.

GEO-CM04S1 - Immunocompromised/Cell Transplant Phase 2 Trial

GEO-CM04S1 is undergoing a Phase 2 multi-site clinical trial (ClinicalTrials.gov Identifier: NCT04977024), evaluating its safety and efficacy, compared to either the Pfizer/BioNTech or Moderna mRNA-based vaccine, as a preventive COVID-19 vaccine in high-risk immunocompromised patients (e.g. patients with blood cancers who have previously received either an allogeneic hematopoietic cell transplant, an autologous hematopoietic cell transplant or chimeric antigen receptor (CAR) T cell therapy). Data published from the open-label safety lead-in portion of the trial indicates that GEO-CM04S1 is highly immunogenic, inducing broad and durable neutralizing antibody and T cell responses.

GEO-CM04S1 - Healthy Adult Booster Phase 2 Trial

A Phase 2 trial of GEO-CM04S1 (ClinicalTrials.gov Identifier: NCT04639466), evaluating two vaccine does levels as a heterologous COVID-19 booster vaccine to current FDA-approved mRNA vaccines from Pfizer/BioNTech and Moderna

In September 2023, we announced completion of enrollment. The trial protocol requires the subjects be followed for 12 months and the last data collection points are scheduled towards the end September 2024. Safety and immune response readouts from this study should be available towards the end of 2024 or early 2025.

S-4

In February 2024, we announced positive interim safety and immune responses findings following vaccine administration. Consolidated data (blinded to vaccine dose) from all subjects tested one-month post-vaccination, documented statistically significant increases in neutralizing antibody responses against multiple SARS-CoV-2 variants, ranging from the original Wuhan strain through Delta and Omicron XBB 1.5.

GEO-CM04S1 - Immunocompromised/CLL Trial Phase 2 Trial

GEO-CM04S1 is undergoing an investigator-initiated Phase 2 clinical trial (ClinicalTrials.gov Identifier: NCT05672355), evaluating its use as a COVID-19 vaccine booster in patients with chronic lymphocytic leukemia (CLL), compared to the Pfizer/BioNTech mRNA-based vaccine. Interim data results are scheduled for Q3 2024.

Gedeptin®- Advanced Head and Neck Cancer Phase 1b/2a Trial

Gedeptin® recently completed a Phase 1b/2a clinical trial (PNP-002) (ClinicalTrials.gov Identifier: NCT03754933) for treatment of patients with advanced head and neck squamous cell carcinoma (HNSCC). This trial was being funded in part by the U.S. Food & Drug Administration (FDA) pursuant to its Orphan Products Clinical Trials Grants Program.

We recently convened a special clinical advisory board to conduct a comprehensive review of the PNP-002 trial results, together with the previously completed Phase 1 trial (PNP-001). This review concluded that Gedeptin demonstrated an acceptable safety and efficacy profile to support continued development. In addition, the therapy has demonstrated sufficient tumor stabilization/reduction activity to support plans to advance clinical development of Gedeptin therapy in an expanded Phase 2 clinical trial.

We have initiated activities in support of a Phase 2 trial in first-recurrence head and neck cancer. The primary goal of this trial will be to establish efficacy of neoadjuvant Gedeptin therapy combined with an immune checkpoint inhibitor in squamous cell head and neck cancer. This trial is anticipated to be a single cycle trial with surgery to follow in approximately 36 patients with pathologic response rate as the primary endpoint. We have initiated the necessary planning activities, including protocol development, manufacturing and CRO selection, with the trial activation anticipated during the first half of 2025.

MVA-Based Vaccine Manufacturing Process Development

In March 2024, we announced a significant milestone toward implementation of a validated chicken embryonic fibroblast (CEF) based production system for our MVA-based vaccines, with the release of the first lot of GEO-CM04S1 produced with a commercial manufacturing platform. This marked the successful completion of the transfer and scale-up of manufacturing to Oxford Biomedica, the Company's cGMP (current Good Manufacturing Procedures) manufacturing partner.

Summary of Risk Factors

Any investment in our securities involves a high degree of risk. You should consider carefully the risks described below, and the more detailed information at "Risk Factors" on page S-11 of this prospectus supplement, together with all of the other information contained in or incorporated by reference into this prospectus supplement and the accompanying prospectus, before you decide whether to purchase our securities:

Risks Related to Our Business and Capital Requirements

We have a history of operating losses, and we expect losses to continue for the foreseeable future.

We have received a going concern opinion from our auditors.

Our business will require continued funding. If we do not receive adequate funding, we may not be able to continue our operations.

Significant disruptions of information technology systems or breaches of information security systems could adversely affect our business.

Risks Related to Development and Commercialization of Product Candidates and Dependence on Third Parties

Our products are still being developed and are unproven. These products may not be successful.

We depend upon key personnel who may terminate their employment with us at any time. If we were to lose the services of any of these individuals, our business and operations may be adversely affected.

Regulatory and legal uncertainties could result in significant costs or otherwise harm our business.

We face intense competition and rapid technological change that could result in products that are superior to, or earlier to the market than, the products we will be commercializing or developing.

Our product candidates are based on new medical technology and, consequently, are inherently risky. Concerns about the safety and efficacy of our products could limit our future success.

We may experience delays in our clinical trials that could adversely affect our financial results and our commercial prospects.

Failure to obtain timely regulatory approvals required to exploit the commercial potential of our products could increase our future development costs or impair our future sales.

State pharmaceutical marketing compliance and reporting requirements may expose us to regulatory and legal action by state governments or other government authorities.

Changes in healthcare law and implementing regulations, as well as changes in healthcare policy, may impact our business in ways that we cannot currently predict, and may have a significant adverse effect on our business and results of operations.

S-7

We may not be successful in establishing collaborations for product candidates we seek to commercialize, which could adversely affect our ability to discover, develop, and commercialize products.

We do not have manufacturing, sales or marketing experience.

Our products under development may not gain market acceptance.

We may be required to defend lawsuits or pay damages for product liability claims.

Reimbursement decisions by third-party payors may have an adverse effect on pricing and market acceptance. If there is not sufficient reimbursement for our products, it is less likely that they will be widely used.

Risks Related to Our Intellectual Property

Our success depends on our ability to obtain, maintain, protect and enforce our intellectual property and our proprietary technologies.

We could lose our license rights to our important intellectual property if we do not fulfill our contractual obligations to our licensors.

Other parties may claim that we infringe their intellectual property or proprietary rights, which could cause us to incur significant expenses or prevent us from selling products.

Any inability to protect our or our licensors' intellectual property rights in the United States and foreign countries could limit our ability to prevent others from manufacturing or selling our products.

Changes in United States patent law could diminish the value of patents in general, thereby impairing our ability to protect our product candidates.

The patent protection and patent prosecution for our product candidates is dependent in part on third parties.

Risks Related to Our Common Stock

See the section entitled "Cautionary Statement Concerning Forward-Looking Information".

Risks Related to Our Business and Capital Requirements

We have a history of operating losses, and we expect losses to continue for the foreseeable future.

As a research and development-focused company, we have had no product revenue to date and revenues from our government grants and other collaborations have not generated sufficient cash flows to cover operating expenses. Since our inception, we have incurred operating losses each year due to costs incurred in connection with research and development activities and general and administrative expenses associated with our operations. We incurred a net loss of approximately $26 million for the year ended December 31, 2023 and of approximately $10.9 million for the six months ended June 30, 2024. We expect to incur additional operating losses and expect cumulative losses to increase as our research and development, preclinical, clinical, and manufacturing efforts expand. Our ability to generate revenue and achieve profitability depends on our ability to successfully complete the development of our product candidates, conduct preclinical tests and clinical trials, obtain the necessary regulatory approvals, and manufacture and market or otherwise commercialize our products. Unless we are able to successfully meet these challenges, we will not be profitable and may not remain in business.

We have received a going concern opinion from our auditors.

We have received a "going concern" opinion from our independent registered public accounting firm, reflecting substantial doubt about our ability to continue as a going concern. Our consolidated financial statements contemplate that we will continue as a going concern and do not contain any adjustments that might result if we were unable to continue as a going concern. Our ability to continue as a going concern is dependent upon our ability to raise additional capital and implement our business plan. If we are unable to achieve or sustain profitability or to secure additional financing on acceptable terms, we may not be able to meet our obligations as they come due, raising substantial doubts as to our ability to continue as a going concern. Any such inability to continue as a going concern may result in our stockholders losing their entire investment. There is no guarantee that we will become profitable or secure additional financing on acceptable terms.

Our business will require continued funding. If we do not receive adequate funding, we may not be able to continue our operations.

To date, we have financed our operations principally through the sale of our equity securities and through government grants and clinical trial support. We will require substantial additional financing at various intervals for our operations, including clinical trials, operating expenses, intellectual property protection and enforcement, for pursuit of regulatory approvals, and for establishing or contracting out manufacturing, marketing and sales functions. There is no assurance that such additional funding will be available on terms acceptable to us or at all. If we are not able to secure the significant funding that is required to maintain and continue our operations at current levels, or at levels that may be required in the future, we may be required to delay clinical studies or clinical trials, curtail operations, or obtain funds through collaborative arrangements that may require us to relinquish rights to some of our products or potential markets.

S-11

We may pursue additional support from the federal government for our vaccine and immunotherapy development programs; however, as we progress to the later stages of our development activities, government financial support may be more difficult to obtain, or may not be available at all. Therefore, it will be necessary for us to look to other sources of funding to finance our development activities.

We will need to raise additional funds to significantly advance our vaccine development programs and to continue our operations. In order to meet our operating cash flow needs we plan to seek sources of non-dilutive capital through government grant programs and clinical trial support. We may also plan additional offerings of our equity securities, debt, or convertible debt instruments. Should the financing we require to sustain our working capital needs be unavailable or prohibitively expensive when we require it, the consequences could have a material adverse effect on our business, operating results, financial condition and prospects.

A significant portion of the funding for the continued development of our next-generation COVID-19 vaccine candidate (GEO-CM04S1) is currently expected to come from BARDA funds, as administered through the RRPV Consortium. If BARDA were to eliminate, reduce or delay funding available to us under the RRPV Contract, this could have a significant, negative impact on our revenues and cash flows, and we may be forced to suspend or terminate the continued development of the product candidate or obtain alternative sources of funding.

In June 2024, we were awarded a contract through the Rapid Response Partnership Vehicle (RRPV) to advance development of GEO-CM04S1, our dual-antigen next-generation COVID-19 vaccine, in a Phase 2b clinical trial (the "RRPV Contract"). Under the agreement, we will sponsor a 10,000-participant, randomized, Phase 2b double-blinded study to assess the clinical efficacy, safety, and immunogenicity of GEO-CM04S1 compared with an FDA-approved mRNA COVID-19 vaccine. The RRPV is a Consortium funded by BARDA.

Preparations for the Phase 2b study are underway, and we expect execution of the study to be fully funded by BARDA under its Clinical Studies Network. The direct award to GeoVax of $24.3 million, which may increase to as much as $45 million, will fund the manufacturing of clinical materials and support for the Phase 2b clinical trial, including regulatory activities. BARDA has made a separate award of $343 million from the Project NextGen program to Allucent, a global clinical research organization (CRO), to execute the clinical trial as part of BARDA's Clinical Studies Network. The combined value of the awards to GeoVax and Allucent toward the clinical evaluation of GEO-CM04S1 is expected to be $367-388 million.

As of June 30, 2024, we have recognized $300,677 in revenue pursuant to the RRPV Contract. We anticipate that a significant portion of the funding to further develop GEO-CM04S1 will come from the remaining amounts to be received under the RRPV Contract. BARDA is entitled to terminate the RRPV Contract for convenience at any time and is not required to provide continued funding beyond reimbursement of amounts currently incurred and obligated by us as a result of contract performance. If the RRPV Contract is terminated or suspended, or if there is any reduction or delay in funding under the RRPV Contract, our revenues and cash flows would be significantly and negatively impacted and we may be forced to seek alternative sources of funding, which may not be available on non-dilutive terms, terms favorable to us, or at all.

Significant disruptions of information technology systems or breaches of information security systems could adversely affect our business.

We rely upon a combination of information technology systems and traditional recordkeeping to operate our business. In the ordinary course of business, we collect, store, and transmit confidential information (including, but not limited to, personal information and intellectual property). We have also outsourced elements of our operations to third parties, including elements of our information technology systems and, as a result, we manage a number of independent vendor relationships with third parties who may or could have access to our confidential information. Our information technology and information security systems and records are potentially vulnerable to security breaches, service interruptions, or data loss from inadvertent or intentional actions by our employees or vendors. Our information technology and information security systems and records are also potentially vulnerable to malicious attacks by third parties. Such attacks are of ever-increasing levels of sophistication and are made by groups and individuals with a wide range of expertise and motives (including, but not limited to, financial crime, industrial espionage, and market manipulation).

S-12

While we have invested, and continue to invest, a portion of our limited funds in our information technology and information security systems, there can be no assurance that our efforts will prevent security breaches, service interruptions, or data losses. Any security breaches, service interruptions, or data losses could adversely affect our business operations and/or result in the loss of critical or sensitive confidential information or intellectual property, and could result in financial, legal, business, and reputational harm to us or allow third parties to gain material, inside information that they may use to trade in our securities.

Risks Related to Development and Commercialization of Product Candidates and Dependence on Third Parties

Our products are still being developed and are unproven. These products may not be successful.

To become profitable, we must generate revenue through sales of our products. However, our products are in varying stages of development and testing. Our products have not been proven in human clinical trials and have not been approved by any government agency for sale. If we cannot successfully develop and prove our products and processes, or if we do not develop other sources of revenue, we will not become profitable and at some point, we would discontinue operations.

We depend upon key personnel who may terminate their employment with us at any time. If we were to lose the services of any of these individuals, our business and operations may be adversely affected.

The success of our business strategy will depend to a significant degree upon the continued services of key management, technical and scientific personnel and our ability to attract and retain additional qualified personnel and managers. Competition for qualified personnel is intense among companies, academic institutions and other organizations. The ability to attract and retain personnel is adversely affected by our financial challenges. If we are unable to attract and retain key personnel and advisors, it may negatively affect our ability to successfully develop, test, commercialize and market our products and product candidates.

Regulatory and legal uncertainties could result in significant costs or otherwise harm our business.

To manufacture and sell our products, we must comply with extensive domestic and international regulation. In order to sell our products in the United States, approval from the U.S. Food and Drug Administration (the "FDA") is required. Satisfaction of regulatory requirements, including FDA requirements, typically takes many years, and if approval is obtained at all, it is dependent upon the type, complexity and novelty of the product, and requires the expenditure of substantial resources. We cannot predict whether our products will be approved by the FDA. Even if they are approved, we cannot predict the time frame for approval. Foreign regulatory requirements differ from jurisdiction to jurisdiction and may, in some cases, be more stringent or difficult to meet than FDA requirements. As with the FDA, we cannot predict if or when we may obtain these regulatory approvals. If we cannot demonstrate that our products can be used safely and successfully in a broad segment of the patient population on a long-term basis, our products would likely be denied approval by the FDA and the regulatory agencies of foreign governments.

We face intense competition and rapid technological change that could result in products that are superior to, or earlier to the market than, the products we will be commercializing or developing.

The market for vaccines that protect against or treat human infectious diseases is intensely competitive and is subject to rapid and significant technological change. We have numerous competitors in the United States and abroad, including, among others, large companies with substantially greater resources than us. If any of our competitors develop products with efficacy or safety profiles significantly better than our products, we may not be able to commercialize our products, and sales of any of our commercialized products could be harmed. Some of our competitors and potential competitors have substantially greater product development capabilities and financial, scientific, marketing and human resources than we do. Competitors may develop products earlier, obtain FDA approvals for products more rapidly, or develop products that are more effective than those under development by us. We will seek to expand our technological capabilities to remain competitive; however, research and development by others may render our technologies or products obsolete or noncompetitive or result in treatments or cures superior to ours.

S-13

Our product candidates are based on new medical technology and, consequently, are inherently risky. Concerns about the safety and efficacy of our products could limit our future success.

We are subject to the risks of failure inherent in the development of product candidates based on new medical technologies. These risks include the possibility that the products we create will not be effective, that our product candidates will be unsafe or otherwise fail to receive the necessary regulatory approvals, and that our product candidates will be difficult to manufacture on a large scale or will be uneconomical to market.

Many pharmaceutical products cause multiple potential complications and side effects, not all of which can be predicted with accuracy and many of which may vary from patient to patient. Long-term follow-up data may reveal previously unidentified complications associated with our products. The responses of potential physicians and others to information about complications could materially adversely affect the market acceptance of our products, which in turn would materially harm our business.

We may experience delays in our clinical trials that could adversely affect our financial results and our commercial prospects.

We do not know whether planned pre-clinical and clinical trials will begin on time or whether we will complete any of our trials on schedule, if at all. Product development costs will increase if we have delays in testing or approvals, or if we need to perform more or larger clinical trials than planned. Significant delays may adversely affect our financial results and the commercial prospects for our products and delay our ability to become profitable.

We rely heavily on independent clinical investigators, vaccine manufacturers, and other third-party service providers for successful execution of our clinical trials, but do not control many aspects of their activities. We are responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. Moreover, the FDA requires us to comply with standards, commonly referred to as Good Clinical Practices, for conducting, recording, and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of trial participants are protected. Our reliance on third parties that we do not control does not relieve us of these responsibilities and requirements. Third parties may not complete activities on schedule or may not conduct our clinical trials in accordance with regulatory requirements or our stated protocols. The failure of these third parties to carry out their obligations could delay or prevent the development, approval and commercialization of our product candidates.

Failure to obtain timely regulatory approvals required to exploit the commercial potential of our products could increase our future development costs or impair our future sales.

None of our vaccines are approved by the FDA for sale in the United States or by other regulatory authorities for sale in foreign countries. To exploit the commercial potential of our technologies, we are conducting and planning to conduct additional pre-clinical studies and clinical trials. This process is expensive and can require a significant amount of time. Failure can occur at any stage of testing, even if the results are favorable. Failure to adequately demonstrate safety and efficacy in clinical trials could delay or preclude regulatory approval and restrict our ability to commercialize our technology or products. Any such failure may severely harm our business. In addition, any approvals we obtain may not cover all of the clinical indications for which approval is sought or may contain significant limitations in the form of narrow indications, warnings, precautions or contraindications with respect to conditions of use, or in the form of onerous risk management plans, restrictions on distribution, or post-approval study requirements.

State pharmaceutical marketing compliance and reporting requirements may expose us to regulatory and legal action by state governments or other government authorities.

Several states have enacted legislation requiring pharmaceutical companies to establish marketing compliance programs and file periodic reports on sales, marketing, pricing and other activities. Similar legislation is being considered in other states. Many of these requirements are new and uncertain, and available guidance is limited. Unless we are in full compliance with these laws, we could face enforcement action, fines, and other penalties and could receive adverse publicity, all of which could harm our business.

S-14

Changes in healthcare law and implementing regulations, as well as changes in healthcare policy, may impact our business in ways that we cannot currently predict, and may have a significant adverse effect on our business and results of operations.

In the United States and foreign jurisdictions, there have been, and continue to be, several legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of product candidates, restrict or regulate post-approval activities, and affect our ability to profitably sell any product candidates for which we obtain marketing approval. Among policy makers and payors in the United States and elsewhere, including in the European Union, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives.

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010 (collectively, the "Affordable Care Act"), substantially changed the way healthcare is financed by both the government and private insurers, and significantly impacts the U.S. pharmaceutical industry. The Affordable Care Act includes a number of provisions that are intended to lower healthcare costs, including provisions relating to prescription drug prices and government spending on medical products.

Since its enactment, there have also been judicial and Congressional challenges to certain aspects of the Affordable Care Act, as well as efforts by the former Trump administration to repeal or replace certain aspects of the statute. We continue to evaluate the effect that the Affordable Care Act and subsequent changes to the statute has on our business. It is uncertain the extent to which any such changes may impact our business or financial condition.

There has also been heightened governmental scrutiny recently over the manner in which drug manufacturers set prices for their marketed products. There have been several Congressional inquiries and proposed bills, as well as state efforts, designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products. In June 2017, the FDA issued a Drug Competition Action plan intended to lower prescription drug prices by encouraging competition from generic versions of existing products. In July 2018, the FDA issued a Biosimilar Action Plan, intended to similarly promote competition to prescription biologics from biosimilars.

Individual states in the United States have also become increasingly aggressive in passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures. For example, in September 2017, the California State Assembly approved SB17, which requires pharmaceutical companies to notify health insurers and government health plans at least 60 days before any scheduled increases in the prices of their products if they exceed 16% over a two-year period, and further requiring pharmaceutical companies to explain the reasons for such increase. Effective in 2016, Vermont passed a law requiring certain manufacturers identified by the state to justify their price increases.

We expect that these, and other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and lower reimbursement, and in downward pressure on the price that we receive for any approved product. Any reduction in reimbursement from Medicare or other government-funded programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize our drugs, once marketing approval is obtained.

S-15

We may not be successful in establishing collaborations for product candidates we seek to commercialize, which could adversely affect our ability to discover, develop, and commercialize products.

We expect to seek collaborations for the development and commercialization of product candidates in the future. The timing and terms of any collaboration will depend on the evaluation by prospective collaborators of the clinical trial results and other aspects of a product's safety and efficacy profile. If we are unable to reach agreements with suitable collaborators for any product candidate, we will be forced to fund the entire development and commercialization of such product candidates, ourselves, and we may not have the resources to do so. If resource constraints require us to enter into a collaboration agreement early in the development of a product candidate, we may be forced to accept a more limited share of any revenues the product may eventually generate. We face significant competition in seeking appropriate collaborators. Moreover, these collaboration arrangements are complex and time-consuming to negotiate and document. We may not be successful in our efforts to establish collaborations or other alternative arrangements for any product candidate. Even if we are successful in establishing collaborations, we may not be able to ensure fulfillment by collaborators of their obligations or our expectations.

We do not have manufacturing, sales, or marketing experience.

We do not have experience in manufacturing, selling, or marketing. To obtain the expertise necessary to successfully manufacture, market, and sell our products, we must develop our own commercial infrastructure and/or collaborative commercial arrangements and partnerships. Our ability to execute our current operating plan is dependent on numerous factors, including, the performance of third-party collaborators with whom we may contract.

Our products under development may not gain market acceptance.

Our products may not gain market acceptance among physicians, patients, healthcare payers and the medical community. Significant factors in determining whether we will be able to compete successfully include:

the efficacy and safety of our products;

the time and scope of regulatory approval;

reimbursement coverage from Medicare, Medicaid, insurance companies and others;

the price and cost-effectiveness of our products, especially as compared to any competitive products; and

the ability to maintain patent protection.

We may be required to defend lawsuits or pay damages for product liability claims.

Product liability is a major risk in testing and marketing biotechnology and pharmaceutical products. We may face substantial product liability exposure in human clinical trials and for products that we sell after regulatory approval. We carry product liability insurance and we expect to continue such policies. However, product liability claims, regardless of their merits, could exceed policy limits, divert management's attention, and adversely affect our reputation and demand for our products.

Reimbursement decisions by third-party payors may have an adverse effect on pricing and market acceptance. If there is not sufficient reimbursement for our products, it is less likely that they will be widely used.

Market acceptance of products we develop, if approved, will depend on reimbursement policies and may be affected by, among other things, future healthcare reform measures. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which drugs they will cover and establish payment levels. We cannot be certain that reimbursement will be available for any products that we may develop. Also, we cannot be certain that reimbursement policies will not reduce the demand for, or the price paid for our products. If reimbursement is not available or is available on a limited basis, we may not be able to successfully commercialize products that we develop.

S-16

Risks Related to Our Intellectual Property

Our success depends on our ability to obtain, maintain, protect, and enforce our intellectual property and our proprietarytechnologies.

In general, our commercial success will depend in part on our and our licensors' ability to obtain, maintain, protect, and enforce our intellectual property and proprietary technologies, including patent protection and trade secret protection for our product candidates, proprietary technologies and their uses as well as our ability to operate without infringing, misappropriating, or otherwise violating the intellectual property rights of others. If we or our licensors are unable to obtain, maintain, protect, or enforce our intellectual property rights or if our intellectual property rights are inadequate for our technology or our product candidates, our competitive position could be harmed, which could have a material adverse impact on our business, results of operations, financial conditions, and prospects. There can be no assurance that our patent applications will result in patents being issued or that issued patents will afford sufficient protection against competitors with similar technologies, nor can there be any assurance that the patents if issued will not be infringed, misappropriated, violated, designed around or invalidated by third parties. Even issued patents may later be found invalid or unenforceable or may be modified or revoked in proceedings instituted by third parties before various patent offices or in courts. The degree of future protection for our intellectual property is uncertain. Only limited protection may be available and may not adequately obtain, maintain, protect, and enforce our rights or permit us to gain or keep any competitive advantage. These uncertainties and/or limitations in our ability to properly obtain, maintain, protect, and enforce the intellectual property rights relating to our product candidates could have a material adverse effect on our financial condition and results of operations.

We cannot be certain that the claims in our in-licensed pending patent applications will be considered patentable by the U.S. Patent and Trademark Office, or USPTO, courts in the United States or by the patent offices and courts in foreign countries, nor can we be certain that claims that may ultimately issue from our patent applications will not be found invalid or unenforceable if challenged. If we or our licensors are unable to obtain or maintain patent protection with respect to our product candidates, our business, financial condition, results of operations, and prospects could be materially harmed.

We could lose our license rights to our important intellectual property if we do not fulfill our contractual obligations to our licensors.

Our rights to significant parts of the technology we use in our products are licensed from third parties and are subject to termination if we do not fulfill our contractual obligations to our licensors. Termination of intellectual property rights under any of our license agreements could adversely impact our ability to produce or protect our products. Our obligations under our license agreements include requirements that we make milestone payments to our licensors upon the achievement of clinical development and regulatory approval milestones, royalties as we sell commercial products, and reimbursement of patent filing and maintenance expenses. Should we become bankrupt or otherwise unable to fulfill our contractual obligations, our licensors could terminate our rights to critical technology that we rely upon.

Other parties may claim that we infringe their intellectual property or proprietary rights, which could cause us to incur significant expenses or prevent us from selling products.

Our success will depend in part on our ability to operate without infringing the patents and proprietary rights of third parties. The manufacture, use and sale of biologic products have been subject to substantial patent litigation in the biopharmaceutical industry. Such lawsuits often relate to the validity or infringement of patents or other proprietary rights of third parties. Pharmaceutical companies, biotechnology companies, universities, research institutions or other third parties may have filed patent applications or may have been granted patents that cover aspects of our products or our licensors' products, product candidates or other technologies.

Future or existing patents issued to third parties may contain patent claims that cover our products or their use or manufacture. In particular, the patent landscape in the COVID-19 vaccine space is crowded, and a large number of patent applications have been filed by numerous entities since January 2020, including for the use of certain SARS-CoV-2 antigens and antigenic combinations, including from Moderna, Janssen Pharmaceuticals, Inc., Sementis LTD., VaxBio, Inc., Oxford University, BioNTech, Ichan School of Medicine at Mount Sinai, Diosynvax LTD., The University of Alberta, University of Texas, and Tonix Pharmaceuticals. If a third party were to assert an infringement claim against us in the future with respect to our current products or with respect to products that we may develop or license, such litigation or interference proceedings could force us to:

stop or delay selling, manufacturing or using products that incorporate, or are made using the challenged intellectual property;

pay damages; or

enter into licensing or royalty agreements that may not be available on acceptable terms, if at all.

Any litigation or interference proceedings, regardless of their outcome, may delay the regulatory approval process, be costly and require significant time and attention of our key management and technical personnel.

S-17

Any inability to protect our or our licensors'intellectual property rights in the United States and foreign countries could limit our ability to prevent others from manufacturing or selling our products.

We will rely on trade secrets, unpatented proprietary know-how, continuing technological innovation and, in some cases, patent protection to preserve our competitive position. Our patents and licensed patent rights may be challenged, invalidated, infringed or circumvented, and the rights granted in those patents may not provide proprietary protection or competitive advantages to us. We and our licensors may not be able to develop patentable products with acceptable patent protection. Even if patent claims are allowed, the claims may not issue, or in the event of issuance, may not be sufficient to protect the technology owned by or licensed to us. If patents containing competitive or conflicting claims are issued to third parties, we may be prevented from commercializing the products covered by such patents or may be required to obtain or develop alternate technology. In addition, other parties may duplicate, design around or independently develop similar or alternative technologies.

Some of our patent families and our in-licensed patent families are in an early stage of prosecution and cannot be enforced against third parties practicing the technology claimed in such applications unless, and until, patents are issued from such applications, and then only to the extent the issued claims cover the third-party technology. There can be no assurance that our patent applications will result in patents being issued or that issued patents will afford sufficient protection against competitors with similar technologies. There can be no assurance that the patents if issued will not be infringed, misappropriated, violated, designed around or invalidated by third parties. Even issued patents may later be found invalid or unenforceable or may be modified or revoked in proceedings instituted by third parties before various patent offices or in courts. The degree of future protection for our intellectual property is uncertain. Only limited protection may be available and may not adequately obtain, maintain, protect, and enforce our rights or permit us to gain or keep any competitive advantage. These uncertainties and/or limitations in our ability to properly obtain, maintain, protect, and enforce the intellectual property rights relating to our product candidates could have a material adverse effect on our financial condition and results of operations.

We may not be able to prevent third parties from infringing or using our intellectual property, and the parties from whom we may license intellectual property may not be able to prevent third parties from infringing or using the licensed intellectual property. We generally attempt to control and limit access to, and the distribution of, our product documentation and other proprietary information. Despite efforts to protect this proprietary information, unauthorized parties may obtain and use information that we may regard as proprietary. Other parties may independently develop similar know-how or may even obtain access to these technologies.

The laws of some foreign countries do not protect proprietary information to the same extent as the laws of the United States, and many companies have encountered significant problems and costs in protecting their proprietary information in these foreign countries.

Furthermore, even if our or our licensors' patent applications are granted, the patent term may be inadequate to protect our competitive position on our product candidates for an adequate amount of time. Patents have a limited lifespan. In the United States, if all maintenance fees are timely paid, the natural expiration of a patent is generally 20 years from its earliest United States non-provisional filing date. Various extensions may be available, but the life of a patent, and the protection it affords, is limited. Even if patents covering our product candidates have been or are obtained, once the patent life has expired, we may be open to competition from competitive products. Given the amount of time required for the development, testing, and regulatory review of product candidates, patents protecting our product candidates might expire before or shortly after such candidates are commercialized. As a result, our patent portfolio may not provide us with sufficient rights to exclude others from commercializing product candidates similar or identical to ours.

Changes in United States patent law could diminish the value of patents in general, thereby impairing our ability to protect our product candidates.

As is the case with other biotechnology companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and enforcing biotechnology patents is costly, time-consuming, and inherently uncertain. Changes in either the patent laws or in the interpretations of patent laws in the United States and other countries may diminish the value of our intellectual property and may increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or defense of issued patents. We cannot predict the breadth of claims that may be allowed or enforced in our patents or in third-party patents. In addition, Congress or other foreign legislative bodies may pass patent reform legislation that is unfavorable to us.

S-18

For example, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, signed into law on September 16, 2011, includes a number of significant changes to U.S. patent law. These include provisions that affect the way patent applications are prosecuted, redefine prior art and provide more efficient and cost-effective avenues for competitors to challenge the validity of patents. These include allowing third-party submission of prior art to the USPTO during patent prosecution and additional procedures to attack the validity of a patent by USPTO administered post-grant proceedings, including post-grant review, inter partes review, and derivation proceedings. Further, because of a lower evidentiary standard in these USPTO post-grant proceedings compared to the evidentiary standard in United States federal courts necessary to invalidate a patent claim, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same evidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to use the USPTO procedures to invalidate our patent claims that would not have been invalidated if first challenged by the third party as a defendant in a district court action. Thus, the Leahy-Smith Act and its implementation can increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have a material adverse effect on our business, financial condition, results of operations and prospects. After March 2013, under the Leahy-Smith Act, the United States transitioned to a first inventor to file system in which, assuming that the other statutory requirements are met, the first inventor to file a patent application is entitled to the patent on an invention regardless of whether a third-party was the first to invent the claimed invention. A third party that files a patent application in the USPTO after March 2013, but before we file an application covering the same invention, could therefore be awarded a patent covering an invention of ours even if we had made the invention before it was made by such third party. This will require us to be cognizant going forward of the time from invention to filing of a patent application. Because patent applications in the United States and most other countries are confidential for a period of time after filing or until issuance, we cannot be certain that we or our licensors were the first to either (i) file any patent application related to our product candidates and other proprietary technologies we may develop or (ii) invent any of the inventions claimed in our or our licensor's patents or patent applications. Even where we have a valid and enforceable patent, we may not be able to exclude others from practicing the claimed invention where the other party can show that they used the invention in commerce before our filing date or the other party benefits from a compulsory license. However, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have a material adverse effect on our business, financial condition, results of operations and prospects.

In addition, the patent positions of companies in the development and commercialization of biologics and pharmaceuticals are particularly uncertain. Recent United States Supreme Court and Federal Circuit rulings have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. For example, recent Federal Circuit rulings such as Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1340 (Fed. Cir. 2010) (en banc), Wyeth & Cordis Corp. v. Abbott Labs, 720 F.3d 1380 (Fed. Cir. 2013), Enzo Life Scis., Inc. v. Roche Molecular Sys., 928 F.3d 1340 (Fed. Cir. 2019), and Idenix Pharms. LLC v. Gilead Scis. Inc., 941 F.3d 1149 (Fed. Cir. 2019), and Amgen Inc. v. Sanofi, 598 U.S. 594 (2023) have significantly heightened the standard for securing broad claims to pharmaceutical and biological products. In addition, recent Federal Circuit rulings such as In re Cellect, 81 F.4th 1216 (Fed. Cir. 2023) have expanded the bases for invalidating a patent under the judicially created doctrine of obviousness-type double patenting.

In addition to heightened patentability requirements, recent Supreme Court and Federal Circuit cases relating to biosimilar product approval under the BPCIA, have held that the "patent dance" provisions of the statute, which are intended to resolve any patent infringement issues before the approval of a biosimilar, are discretionary, and a biosimilar applicant can opt out by refusing to provide a copy of its application and manufacturing information to the biologic sponsor (see Sandoz Inc. v. Amgen Inc.,137 S. Ct. 1664 (2017). It may be that we do not learn of a biosimilar application until after FDA publishes its approval (see Immunex v. Samsung Bioepsis, 2:19-cv-117555-CCC-MF (D.N.J. Apr. 30, 2019). In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on decisions by Congress, the United States federal courts, the USPTO, or similar authorities in foreign jurisdictions, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents we might obtain in the future.

S-19

The patent protection and patent prosecution for our product candidates is dependent in part on third parties.

We or our licensors may fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. Therefore, we may miss potential opportunities to strengthen our patent position. It is possible that defects of form in the preparation or filing of our patents or patent applications may exist, or may arise in the future, for example, with respect to proper priority claims, inventorship, claim scope, or requests for patent term adjustments. If we or our licensors, fail to establish, maintain, or protect such patents and other intellectual property rights, such rights may be reduced or eliminated. If our licensors are not fully cooperative or disagree with us as to the prosecution, maintenance, or enforcement of any patent rights, such patent rights could be compromised. If there are material defects in the form, preparation, prosecution, or enforcement of our patents or patent applications, such patents may be invalid and/or unenforceable, and such applications may never result in valid, enforceable patents. Any of these outcomes could impair our ability to prevent competition from third parties, which may have an adverse impact on our business.

We rely on third parties to file and prosecute patent applications and maintain patents and otherwise protect the licensed intellectual property under some of our license agreements. We have not had and do not have primary control over these activities for some of our in-licensed patents or patent applications and other intellectual property rights. We cannot be certain that such activities by third parties have been or will be conducted in compliance with applicable laws and regulations or will result in valid and enforceable patents or other intellectual property rights. Pursuant to the terms of the license agreements with some of our licensors, the licensors may have the right to control enforcement of our licensed patents or defense of any claims asserting the invalidity of these patents and even if we are permitted to pursue such enforcement or defense, we will require the cooperation of our licensors. We cannot be certain that our licensors will allocate sufficient resources or prioritize their or our enforcement of such patents or defense of such claims to protect our interests in the licensed patents. Even if we are not a party to these legal actions, an adverse outcome could harm our business because it might prevent us from continuing to license intellectual property that we may need to operate our business. If any of our licensors fail to appropriately prosecute and maintain patent protection for patents covering our product candidates, our ability to develop and commercialize those product candidates may be adversely affected and we may not be able to prevent competitors from making, using, and selling competing products.

In addition, even where we have the right to control patent prosecution of patents and patent applications we have acquired or licensed from third parties, we may still be adversely affected or prejudiced by actions or inactions of our predecessors or licensors and their counsel that took place prior to us assuming control over patent prosecution.

Our technology acquired or licensed from various third parties may be subject to retained rights. Our predecessors or licensors often retain certain rights under their agreements with us, including the right to use the underlying technology for non-commercial academic and research use, to publish general scientific findings from research related to the technology, and to make customary scientific and scholarly disclosures of information relating to the technology. It is difficult to monitor whether our predecessors or licensors limit their use of the technology to these uses, and we could incur substantial expenses to enforce our rights to our licensed technology in the event of misuse.

In addition, the research resulting in certain of our in-licensed patent rights and technology was funded in part by the United States government. As a result, the government may have certain rights, or march-in rights, to such patent rights and technology. When new technologies are developed with government funding, the government generally obtains certain rights in any resulting patents, including a nonexclusive license authorizing the government to use the invention for noncommercial purposes. These rights may permit the government to disclose our confidential information to third parties and to exercise march-in rights to use or allow third parties to use our licensed technology. The United States government also has the right to take title to these inventions if the applicable licensor fails to disclose the invention to the government or fails to file an application to register the intellectual property within specified time limits. The government can exercise its march-in rights if it determines that action is necessary because we fail to achieve practical application of the government-funded technology, because action is necessary to alleviate health or safety needs, to meet requirements of federal regulations, or to give preference to United States industry. In addition, our rights in such inventions may be subject to certain requirements to manufacture products embodying such inventions in the United States. Any exercise by the government of such rights could harm our competitive position, business, financial condition, results of operations, and prospects.

Risks Related to Our Common Stock

The market price of our common stock is highly volatile.

The market price of our common stock has been, and is expected to continue to be, highly volatile. Certain factors, including announcements of new developments by us or other companies, regulatory matters, new or existing medicines or procedures, concerns about our financial position, operating results, litigation, government regulation, developments or disputes relating to agreements, patents or proprietary rights, may have a significant impact on the market price of our stock. In addition, potential dilutive effects of future sales of shares of common stock by us, and subsequent sales of common stock by the holders of our options and warrants could have an adverse effect on the market price of our shares.

In addition, the securities markets from time-to-time experience significant price and volume fluctuations that are unrelated to the operating performance of particular companies. These market fluctuations may also materially and adversely affect the market price of our common stock.

The sale or issuance of additional shares of our common stock or other equity securities could result in additional dilution to our stockholders.

In order to meet our operating cash flow needs, we may plan additional offerings of our equity securities, debt, or convertible debt instruments. The sale of additional equity securities could result in significant additional dilution to our stockholders. The incurrence of indebtedness could result in debt service obligations and operating and financing covenants that would restrict our operations. We cannot assure investors that financing will be available in amounts or on terms acceptable to us, if at all.

We are obligated to issue additional shares of our common stock in connection with our outstanding warrants if the warrant holders choose to exercise them. There are outstanding warrants exercisable for 6,617,747 shares at exercise prices ranging from $1.68 to $195 per share ($5.37 weighted average). The exercise of these warrants will cause us to issue additional shares of our common stock and will dilute the percentage ownership of our shareholders.

Certain provisions of our certificate of incorporation which authorize the issuance of shares of preferred stock may make it more difficult for a third party to effect a change in control.

Our certificate of incorporation authorizes our Board of Directors to issue up to 10,000,000 shares of preferred stock. The shares of preferred stock may be issued in one or more series, the terms of which may be determined at the time of issuance by our Board of Directors without further action by the stockholders. These terms may include voting rights, including the right to vote as a series on particular matters, preferences as to dividends and liquidation, conversion rights, redemption rights and sinking fund provisions. The issuance of any newly issued preferred stock could diminish the rights of holders of our common stock, and therefore could reduce the value of our common stock. In addition, specific rights granted to future holders of preferred stock could be used to restrict our ability to merge with, or sell assets to, a third party. The ability of our Board of Directors to issue preferred stock could make it more difficult, delay, discourage, prevent or make it costlier to acquire or effect a change-in-control, which in turn could prevent the stockholders from recognizing a gain in the event that a favorable offer is extended and could materially and negatively affect the market price of our common stock.

We have never paid dividends and have no plans to do so.

Holders of shares of our common stock are entitled to receive such dividends as may be declared by our Board of Directors. To date, we have paid no cash dividends on our shares of common stock and we do not expect to pay cash dividends on our common stock in the foreseeable future. We intend to retain future earnings, if any, to provide funds for operations of our business. Therefore, any potential return investors may have in our common stock will be in the form of appreciation, if any, in the market value of their shares of common stock.

S-21

Public company compliance may make it more difficult for us to attract and retain officers and directors.

The Sarbanes-Oxley Act, the Dodd-Frank Act, the JOBS Act, the FAST Act, and rules subsequently implemented by the SEC have required changes in corporate governance practices of public companies. As a public company, we expect these rules and regulations, and amendments to them, to contribute to our compliance costs and to make certain activities more time consuming and costly. As a public company, we also expect that these rules and regulations may make it difficult and expensive for us to obtain director and officer liability insurance and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be difficult for us to attract and retain qualified persons to serve on our board of directors or as executive officers.

Our Certificate of Incorporation and Bylaws may be amended by the affirmative vote of a majority of our stockholders.

Under the Delaware General Corporation Law, a corporation's certificate of incorporation may be amended by the affirmative vote of the holders of a majority of the outstanding shares entitled to vote, and a majority of the outstanding shares of each class entitled to vote as a class, unless the articles require the vote of a larger percentage of shares. Our Certificate of Incorporation, as amended, does not require the vote of a larger percentage of shares. As permitted under the Delaware General Corporation Law, our Bylaws give our board of directors the power to adopt, amend, or repeal our Bylaws. Our stockholders entitled to vote have concurrent power to adopt, amend, or repeal our Bylaws.

Broker-dealers may be discouraged from effecting transactions in shares of our common stock if we are considered to be a penny stock and thus subject to the penny stock rules.

The SEC has adopted a number of rules to regulate "penny stocks" that restrict transactions involving stock which is deemed to be penny stock. Such rules include Rules 3a51-1, 15g-1, 15g-2, 15g-3, 15g-4, 15g-5, 15g-6, 15g-7, and 15g-9 under the Exchange Act. These rules may have the effect of reducing the liquidity of penny stocks. "Penny stocks" generally are equity securities with a price of less than $5.00 per share (other than securities registered on certain national securities exchanges or quoted on Nasdaq if current price and volume information with respect to transactions in such securities is provided by the exchange or system). Our securities have in the past constituted, and may again in the future, if we are delisted from Nasdaq, constitute, "penny stock" within the meaning of the rules. The additional sales practice and disclosure requirements imposed upon U.S. broker-dealers may discourage broker-dealers from effecting transactions in shares of our common stock, which could severely limit the market liquidity of such shares and impede their sale in the secondary market.

A U.S. broker-dealer selling penny stock to anyone other than an established customer or "accredited investor" (generally, an individual with net worth in excess of $1,000,000 (exclusive of personal residence) or an annual income exceeding $200,000, or $300,000 together with his or her spouse) must make a special suitability determination for the purchaser and must receive the purchaser's written consent to the transaction prior to sale, unless the broker-dealer or the transaction is otherwise exempt. In addition, the "penny stock" regulations require the U.S. broker-dealer to deliver, prior to any transaction involving a "penny stock", a disclosure schedule prepared in accordance with SEC standards relating to the "penny stock" market, unless the broker-dealer or the transaction is otherwise exempt. A U.S. broker-dealer is also required to disclose commissions payable to the U.S. broker-dealer and the registered representative and current quotations for the securities. Finally, a U.S. broker-dealer is required to submit monthly statements disclosing recent price information with respect to the "penny stock" held in a customer's account and information with respect to the limited market in "penny stocks".

Stockholders should be aware that, according to the SEC, the market for "penny stocks" has suffered in recent years from patterns of fraud and abuse. Such patterns include (i) control of the market for the security by one or a few broker-dealers that are often related to the promoter or issuer; (ii) manipulation of prices through prearranged matching of purchases and sales and false and misleading press releases; (iii) "boiler room" practices involving high-pressure sales tactics and unrealistic price projections by inexperienced sales persons; (iv) excessive and undisclosed bid-ask differentials and markups by selling broker-dealers; and (v) the wholesale dumping of the same securities by promoters and broker-dealers after prices have been manipulated to a desired level, resulting in investor losses. Our management is aware of the abuses that have occurred historically in the penny stock market. Although we do not expect to be in a position to dictate the behavior of the market or of broker-dealers who participate in the market, management will strive within the confines of practical limitations to prevent the described patterns from being established with respect to our securities.

Additional Risks Related to this Offering.

The common stock offered hereby will be sold in "at the market offerings,"and investors who buy shares at different times will likely pay different prices.

Investors who purchase shares in this offering at different times will likely pay different prices. As a result, investors may experience different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices and numbers of shares sold, and there is no minimum or maximum sales price. Investors may experience a decline in the value of their shares as a result of share sales made at prices lower than the prices they paid.

The actual number of shares of common stock we will issue under the Sales Agreement, at any one time or in total, is uncertain.

Subject to certain limitations in the Sales Agreement and compliance with applicable law, we have the discretion to deliver a sales notice to A.G.P. as our sales agent at any time throughout the term of the Sales Agreement. The number of shares that are sold by A.G.P. after delivering a sales notice will fluctuate based on the market price of our common stock during the sales period and limits we set with A.G.P. Because the price per share of each share sold will fluctuate based on the market price of our common stock during the sales period, it is not possible at this stage to predict the number of shares that will be ultimately issued.

We have broad discretion in determining how to use the proceeds from this offering and we cannot assure you that we will be successful in spending the proceeds in ways which increase our profitability or market value, or otherwise yield favorable returns.

We plan to utilize the proceeds of this offering for general working capital. Nevertheless, we will have broad discretion in determining specific expenditures. You will be entrusting your funds to our management, upon whose judgment you must depend, with limited information concerning the purposes to which the funds will ultimately be applied. We may not be successful in spending the proceeds of this offering in ways which increase our profitability or market value, or otherwise yield favorable returns.

Fluctuations in the price of our common stock, including as a result of actual or anticipated sales of shares by stockholders, may make our common stock more difficult to resell.

The market price and trading volume of our common stock have been and may continue to be subject to significant fluctuations due not only to general stock market conditions, but also to changes in sentiment in the market regarding the industry in which we operate, our operations, business prospects or liquidity or this offering. In addition to the risk factors discussed in our periodic reports and in this prospectus supplement, the price and volume volatility of our common stock may be affected by actual or anticipated sales of common stock by existing stockholders, including of shares purchased in this offering, whether in the market or in subsequent public offerings. Stock markets in general may experience extreme volatility that is unrelated to the operating performance of listed companies. These broad market fluctuations may adversely affect the trading price of our common stock, regardless of our operating results. As a result, these fluctuations in the market price and trading volume of our common stock may make it difficult to predict the market price of our common stock in the future, cause the value of your investment to decline and make it more difficult to resell our common stock.

S-23

If we are not able to comply with the applicable continued listing requirements or standards of the Nasdaq Capital Market, Nasdaq could delist our common stock.

Our common stock (GOVX) is currently listed on the Nasdaq Capital Market. In order to maintain that listing, we must satisfy minimum financial and other continued listing requirements and standards, including those regarding director independence and independent committee requirements, minimum stockholders' equity, minimum share price, and certain corporate governance requirements. There can be no assurances that we will be able to continue to comply with the applicable listing standards.

On May 23, 2024, the Company received a notice from the Listing Qualifications Department of Nasdaq notifying the Company that it no longer complied with the $2,500,000 minimum stockholders' equity required for continued listing pursuant to Nasdaq Listing Rule 5550(b)(1) (the "Stockholders' Equity Requirement"), because the Company's stockholders' equity as reported in its Form 10-Q for the period ended March 31, 2024 did not meet the required minimum, and as of the date of the Notice, the Company did not meet the alternatives of market value of listed securities or net income from continuing operations (together with the Stockholders' Equity Requirement, the "Listing Rule").

On July 18, 2024, we received notice from Nasdaq granting our request for an extension of time to regain compliance with the Stockholders' Equity Requirement until November 19, 2024. We believe that our recent equity transactions are sufficient to remedy the shortfall in our stockholders' equity at our next quarterly reporting date of September 30, 2024, but have not yet received a determination from Nasdaq. If we are unable to maintain compliance with these Nasdaq Capital Market requirements, our common stock will be delisted from the Nasdaq Capital Market. In that event, and if our common stock is not then eligible for quotation on another market or exchange, 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 OTC Pink. In such event, it could become more difficult to dispose of, or obtain accurate price quotations for, our common stock, and there would likely also be a reduction in our coverage by securities analysts and the news media, which could cause the price of our common stock to decline further. Also, it may be difficult for us to raise additional capital if we are not listed on an exchange.

Investors in this offering may suffer immediate and substantial dilution in the net tangible book value per share of our common stock.

Because the price per share of common stock in this offering may be substantially higher than the net tangible book value per share of common stock, investors in this offering may suffer immediate and substantial dilution in the net tangible book value per share of common stock. The shares in this offering will be sold at market prices which may fluctuate substantially. For purposes of calculating dilution, we have assumed a sale price of $2.95 per share which was the closing price of our stock on September 20, 2024. However, since the shares may be sold at a variety of prices, these dilution numbers may not be accurate. Assuming that we sell aggregate of 1,520,965 shares of our common stock at a price of $2.95 per share, the last reported sale price of our common stock on Nasdaq on September 20, 2024, for aggregate gross proceeds of $4,486,846, after deducting commissions and estimated offering expenses payable by us, you will experience a decrease in net tangible book value per share of $2.60 per share, representing the difference between our as adjusted net tangible book value per share as of June 30, 2024 after giving effect to this offering at the assumed offering price. See the section entitled "Dilution" below for a more detailed illustration of the dilution you would incur if you participate in this offering.

If securities or industry analysts do not publish or cease publishing research or reports about us, our business or our market, or if they change their recommendations regarding our common stock adversely, our common stock price and trading volume could decline.

The trading market for our shares of common stock will be influenced by many factors, including without limitation, the research and reports that industry or securities analysts may publish about us, our business, our market or our competitors. If any of the analysts who may cover us change their recommendation regarding our common stock adversely, or provide more favorable relative recommendations about our competitors, our share price would likely decline. If any analyst who may cover us were to cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our common stock price or trading volume to decline.

S-24

In making your investment decision, you should understand that we and A.G.P. have not authorized any other party to provide you with information concerning us or this offering.

You should carefully evaluate all of the information in this prospectus supplement before investing in our company. We may receive media coverage regarding our company, including coverage that is not directly attributable to statements made by our officers, that incorrectly reports on statements made by our officers or employees, or that is misleading as a result of omitting information provided by us, our officers or employees. We and A.G.P. have not authorized any other party to provide you with information concerning us or this offering, and you should not rely on this information in making an investment decision.

An active, liquid trading market for our common stock may not develop, which may cause our common stock to trade at a discount from the offering price and make it difficult for you to sell the common stock you purchase.

Our common stock is currently listed on the Nasdaq Capital Market. However, there can be no assurance that there will be an active market for our common stock either now or in the future. If an active and liquid trading market does not develop or if developed cannot be sustained, you may have difficulty selling any of our common stock that you purchase. The market price of our common stock may decline below the initial offering price, and you may not be able to sell your shares of our common stock at or above the price you paid, or at all.

S-25

USE OF PROCEEDS

We may issue and sell shares of our common stock having aggregate sales proceeds of up to $4,486,846 from time to time. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. We estimate that the maximum net proceeds from the sale of the shares of common stock that we are offering may be up to approximately $4,302,241, at an assumed offering price of $2.95 per share, the last reported sale price of our common stock on The Nasdaq Capital Market on September 20, 2024, and after deducting A.G.P.'s commission and estimated offering expenses payable by us.

We intend to use the net proceeds from this offering to advance our product candidates, including research and technical development, manufacturing, clinical studies, capital expenditures, and working capital. We may also use the net proceeds from this offering to acquire and invest in complementary products, technologies or businesses; however, we currently have no agreements or commitments to complete any such transaction.

As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses of the proceeds from this offering. We may find it necessary or advisable to use the net proceeds for other purposes, and we will have broad discretion in using these proceeds. Investors will be relying on our judgment regarding the use of the net proceeds from this offering. Pending the use of proceeds as described above, we plan to invest the net proceeds that we receive in short-term and intermediate-term interest-bearing obligations, investment-grade investments, certificates of deposit or direct or guaranteed obligations of the U.S. government. We cannot predict whether the invested proceeds will yield a favorable return.

S-26

DILUTION

If you invest in our common stock in this offering, your interest will be diluted to the extent of the difference between the offering price per share of common stock and the as adjusted net tangible book value per share of common stock immediately after this offering.

Our net tangible book value is the amount of our total tangible assets less our total liabilities. Net tangible book value per share is our net tangible book value divided by the number of shares of common stock. Our net tangible book value as of June 30, 2024 was $(2,309,226), or $(0.55) per share, based on 4,178,700 shares of our common stock outstanding at that date.

The shares in this offering will be sold at market prices which may fluctuate substantially. For purposes of calculating dilution, we have assumed a sale price of $2.95 per share, which was the closing price of our stock on September 20, 2024.

After giving effect to the sale of our common stock in the aggregate amount of $4,486,846, or 1,520,965 shares, at an assumed offering price of $2.95 per share, after deducting estimated commissions and offering expenses payable by us, our as adjusted net tangible book value as of June 30, 2024 would have been approximately $1,993,015, or $0.35 per share of common stock. This represents an immediate increase in net tangible book value of $0.90 per share to existing stockholders and immediate decrease in net tangible book value of $2.60 per share to new investors purchasing our common stock in this offering at the public offering price. The following table illustrates this calculation on a per share basis:

Assumed public offering price per share

$ 2.95

Net tangible book value per share as of June 30, 2024

$ (0.55 )

Increase in net tangible book value per share attributable to this offering

$ 0.90

As adjusted net tangible book value per share as of June 30, 2024 after giving effect to this offering

$ 0.35

Dilution per share to investors purchasing our common stock in this offering

$ (2.60 )

The shares subject to the Sales Agreement are being sold from time to time at various prices. An increase of $0.50 per share in the price at which the shares are sold from the assumed public offering price of $2.95 per share shown in the table above, assuming all of our common stock in the aggregate amount of $4,486,846 during the term of the Sales Agreement are sold at that price, would increase our as adjusted net tangible book value per share to $0.36and result in dilution in net tangible book value per share to investors in this offering of $3.09 per share, after deducting estimated offering commissions and estimated aggregate offering expenses payable by us. A decrease of $0.50 per share in the price at which the shares are sold from the assumed public offering price of $2.95 per share shown in the table above, assuming all of our common stock in the aggregate amount of $4,486,846 during the term of the Sales Agreement is sold at that price, would decrease our as adjusted net tangible book value per share after the offering to $0.33 per share and would result in dilution in net tangible book value per share to new investors in this offering of $2.12 per share, after deducting estimated commissions and estimated aggregate offering expenses payable by us. This information is supplied for illustrative purposes only and may differ based on the actual offering price and the actual number of shares offered.

The foregoing discussion and table do not take into account further dilution to investors in this Offering that could occur upon the exercise of outstanding warrants having a per share exercise or conversion price less than the per share offering price to the public in this offering. We may also choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

PLAN OF DISTRIBUTION

We have entered into the Sales Agreement with A.G.P./Alliance Global Partners, under which we may issue and sell shares of our common stock from time to time through or to A.G.P. acting as sales agent or principal, including sales having an aggregate gross sales price of up to $4,486,846 pursuant to this prospectus supplement.

A.G.P. may sell the shares of common stock by any method that is deemed to be an "at the market offering" as defined in Rule 415(a)(4) promulgated under the Securities Act. If we and A.G.P. agree on a method of distribution other than sales of shares of our common stock on or through Nasdaq or another existing trading market at market prices, we will file a further prospectus supplement providing all information about such offering as required by Rule 424(b) under the Securities Act.

A.G.P. will offer the shares of our common stock subject to the terms and conditions of the Sales Agreement on a daily basis or as otherwise agreed upon by us and A.G.P. We will designate the maximum number of shares of common stock to be sold through A.G.P. on a daily basis or otherwise determine such maximum number together with A.G.P. Subject to the terms and conditions of the Sales Agreement, A.G.P. will use its commercially reasonable efforts to sell on our behalf all of the shares of common stock so designated or determined. We may instruct A.G.P. not to sell shares of common stock if the sales cannot be effected at or above the price designated by us in any such instruction. We or A.G.P. may suspend the offering of shares of common stock being made through A.G.P. under the Sales Agreement upon proper notice to the other party.

We will pay A.G.P. commissions, in cash, for its services in acting as agent in the sale of our common stock. A.G.P. will be entitled to compensation at a fixed commission rate of 3.0% of the aggregate gross proceeds from each sale of our common stock. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. We have also agreed to reimburse A.G.P. for certain specified fees and documented expenses, including the fees and documented expenses of its legal counsel in an amount not to exceed $50,000, as provided in the Sales Agreement. Additionally, pursuant to the terms of the Sales Agreement, we agreed to reimburse A.G.P. for the documented fees and costs of its legal counsel reasonably incurred in connection with A.G.P.'s ongoing diligence, drafting and other filing requirements arising from the transactions contemplated by the Sales Agreement in an amount not to exceed $5,000 in the aggregate per quarter. We estimate that the total expenses for the offering, excluding compensation and reimbursements payable to A.G.P. under the terms of the Sales Agreement, will be approximately $20,000.

Settlement for sales of common stock will occur on the first business day following the date on which any sales are made or such shorter settlement cycle as may be in effect under the Exchange Act from time to time, or on some other date that is agreed upon by us and A.G.P. in connection with a particular transaction, in return for payment of the net proceeds to us. Sales of our common stock as contemplated in this prospectus supplement will be settled through the facilities of The Depository Trust Company or by such other means as we and A.G.P. may agree upon. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

A.G.P. is not required to sell any certain number of shares or dollar amount of our common stock, but A.G.P. will use its commercially reasonable efforts consistent with its normal trading and sales practices to sell on our behalf all of the shares of common stock requested to be sold by us, subject to the conditions set forth in the Sales Agreement. In connection with the sale of the common stock on our behalf, A.G.P. will be deemed to be an "underwriter" within the meaning of the Securities Act and the compensation of A.G.P. will be deemed to be underwriting commissions or discounts. We have agreed to provide indemnification and contribution to A.G.P. against certain civil liabilities, including liabilities under the Securities Act.

The offering of our common stock pursuant to the Sales Agreement will terminate upon the earlier of the (i) sale of all of our shares of common stock provided for in this prospectus supplement or (ii) termination of the Sales Agreement as permitted therein.

A.G.P. and its affiliates may in the future provide various advisory, investment and commercial banking and other services to us in the ordinary course of business, for which they may in the future receive customary fees. To the extent required by Regulation M, A.G.P. will not engage in any market making activities involving our shares of common stock while the offering is ongoing under this prospectus supplement.

Although we believe that the expectations reflected in such forward-looking statements are based upon reasonable assumptions at the time made, we can give no assurance that such expectations will be achieved.

Our programs are in various stages of development, the most significant of which are summarized below along with recent developments:

GEO-CM04S1 -Immunocompromised Trial

● GEO-CM04S1 is currently undergoing a Phase 2 clinical trial (ClinicalTrials.gov Identifier: NCT04977024), evaluating its safety and efficacy, compared to either the Pfizer/BioNTech or Moderna mRNA-based vaccine, as a preventive COVID-19 vaccine in high-risk immunocompromised patients (e.g. patients who have previously received either an allogeneic hematopoietic cell transplant, an autologous hematopoietic cell transplant or chimeric antigen receptor (CAR) T cell therapy).

3

● In September 2023, the journal, Vaccines, published data from the open-label safety portion of the trial indicating that GEO-CM04S1 is highly immunogenic, inducing both antibody responses, including neutralizing antibodies, and T cell responses.

● In September 2023, preclinical vaccine efficacy data for GEO-CM02 were presented during the Keystone Symposia on Molecular and Cellular Biology, Vaccinology During and After COVID-19, demonstrating that our multi-antigen SARS-CoV-2 vaccine, GEO-CM02, induced efficacious immune responses against the original Wuhan strain and BA.1 Omicron variant with a single dose. The data generated in the GEO-CM02 studies validate our hypothesis that vaccines such as GEO-CM04S1, which are designed to induce both antibodies and T-cells to multiple viral structural proteins, can address the issue of viral variation and escape from the immune system.

● In October 2023, we announced commencement of the planned site expansion for this trial to accelerate patient enrollment. In addition to study enrollments completed at the City of Hope Medical Center (Duarte, California), the trial is now open to eligible patients at Wake Forest Baptist Medical Center (Winston Salem, North Carolina), the University of Massachusetts Medical Center (Worcester, Massachusetts), and the Fred Hutchinson Cancer Center (Seattle, Washington).

GEO-CM04S1 -Healthy Booster Trial

● GEO-CM04S1 is undergoing the Phase 2 portion of a Phase 1/2 trial (ClinicalTrials.gov Identifier: NCT04639466), evaluating its use as a universal COVID-19 booster vaccine to current FDA-approved two-shot mRNA vaccines from Pfizer/BioNTech and Moderna.

● In September 2023, we announced the completion of patient enrollment for this trial.

GEO-CM04S1 -CLL Trial

● In July 2023, an investigator-initiated Phase 2 clinical trial (ClinicalTrials.gov Identifier: NCT05672355) of GEO-CM04S1 began, evaluating its use as a COVID-19 booster vaccine in patients with chronic lymphocytic leukemia (CLL), compared to the Pfizer/BioNTech mRNA-based vaccine.

Gedeptin®-Advanced Head and Neck Cancer Trial

● Gedeptin® is currently undergoing a Phase 1/2 clinical trial (ClinicalTrials.gov Identifier: NCT03754933) for treatment of patients with advanced head and neck squamous cell carcinoma (HNSCC). This trial is being funded in part by the U.S. Food & Drug Administration (FDA) pursuant to its Orphan Products Clinical Trials Grants Program. The trial is designed to inform the design of a larger patient trial that also may involve patients with other anatomically accessible oral and pharyngeal cancers, including cancers of the lip, tongue, gum, floor of mouth, salivary gland and other oral cavities.

● In July 2023, interim data were presented at the American Association for Cancer Research (AACR) and the American Head and Neck Society (AHNS) joint Head and Neck Cancer Conference, indicating that administration of Gedeptin® is safe and feasible, with observation of tumor growth impairment in a majority of the patients.

Advanced Vaccine Manufacturing Process Development

● In September 2023, GeoVax and ProBioGen AG announced the signing of a commercial license agreement for ProBioGen's AGE1.CR.pIX® suspension cell line. The agreement enhances our manufacturing capabilities for our entire Modified Vaccinia Ankara (MVA)-based vaccine portfolio. This follows the May 2023 execution of a Master Services Agreement with Advanced Bioscience Laboratories, Inc. (ABL) to support current Good Manufacturing Practices (cGMP) production of our vaccine candidates through late-stage development toward eventual commercialization. These agreements move the Company toward implementing a continuous cell line manufacturing system to provide lower-cost, scalable versatility for our entire MVA-based vaccine portfolio.

Intellectual Property Development

● In October 2023, the U.S. Patent and Trademark Office issued a Notice of Allowance to GeoVax for Patent Application No. 17/584,231 titled "Replication Deficient Modified Vaccina Ankara (MVA) Expressing Marburg Virus Glycoprotein (GP) and Matrix Protein (VP40)." The allowed claims generally cover GeoVax's vector platform for expressing Marburg virus antigens in virus-like particles (VLPs) utilizing an MVA viral vector.

● In October 2023, the U.S Patent and Trademark Office issued a Notice of Allowance to GeoVax for Patent Application No. 17/409,574 titled "Multivalent HIV Vaccine Boost Compositions and Methods of Use." The allowed claims generally cover a priming vaccination with a DNA vector encoding multiple HIV antigens in virus-like particles (VLPs), followed by a boost vaccination with GeoVax's vector platform for expressing HIV-1 antigens in VLPs utilizing an MVA viral vector.

● In August 2023, the U.S. Patent and Trademark Office issued a Notice of Allowance to GeoVax for Patent Application No. 17/726,254 titled "Compositions and Methods for Generating an Immune Response to Treat or Prevent Malaria". The allowed claims cover compositions comprising GeoVax's modified vaccinia Ankara (MVA) vector expressing Plasmodium antigens and methods of inducing an immune response to malaria utilizing the compositions. The compositions and methods covered in the allowed claims are useful both prophylactically and therapeutically and may be used to prevent and/or treat malaria.

● In July 2023, the U.S. Patent and Trademark Office issued Patent No. 11,701,418 B2 to GeoVax, pursuant to the Company's patent application No. 15/543,139 titled "Replication-Deficient Modified Vaccinia Ankara (MVA) and Matrix Protein (VP40), covering GeoVax's vector platform for expressing ebolavirus antigens in virus-like particles (VLPs) utilizing an MVA viral vector. The claims encompass multiple ebolavirus strains, including Sudan ebolavirus, Zaire ebolavirus, Taï Forest ebolavirus, and Reston ebolavirus.

December 2023 Private Placement

On December 2, 2023, we entered into a common stock warrant exercise inducement offer letter (the "Inducement Letter") with the holder (the "Holder") of existing warrants to purchase shares of the Company's common stock at an exercise price of $48.90 per share, issued on January 19, 2022 and warrants to purchase shares of the Company's common stock at an exercise price of $24.75 per share issued on May 27, 2022 (together, the "Existing Warrants"), pursuant to which the Holder agreed to exercise for cash its Existing Warrants to purchase an aggregate of 704,499 shares of the Company's common stock, at a reduced exercised price of $6.21 per share, in consideration for the Company's agreement to issue a warrant (the "2023 Common Warrant") to purchase up to 1,408,998 common shares with an exercise price of $6.21 share, exercisable at any on or after six months from the date of issuance and will expire five and one-half (5 ½) years following the date of issuance.

The Securities That May Be Offered

We may offer or sell common stock, preferred stock, warrants and units in one or more offerings and in any combination. The aggregate offering price of the securities we sell pursuant to this prospectus will not exceed $100,000,000. Each time securities are offered with this prospectus, we will provide a prospectus supplement that will describe the specific amounts, prices and terms of the securities being offered and the net proceeds we expect to receive from that sale.

The securities may be sold to or through underwriters, dealers or agents or directly to purchasers or as otherwise set forth in the section titled "Plan of Distribution." Each prospectus supplement will set forth the names of any underwriters, dealers, agents or other entities involved in the sale of securities described in that prospectus supplement and any applicable fee, commission or discount arrangements with them.

We may offer shares of our common stock, par value $0.001 per share, either alone or underlying other registered securities convertible into our common stock. Holders of our common stock are entitled to receive dividends declared by our board of directors out of funds legally available for the payment of dividends, subject to rights, if any, of preferred stockholders. We have not paid dividends in the past and have no current plans to pay dividends. Each holder of common stock is entitled to one vote per share. The holders of common stock have no preemptive rights.

5

Preferred Stock

Our board of directors has the authority, subject to limitations prescribed by Delaware law, to issue preferred stock in one or more series, to establish from time to time the number of shares to be included in each series, and to fix the designation, powers, preferences and rights of the shares of each series and any of its qualifications, limitations or restrictions, in each case without further vote or action by our stockholders. Each series of preferred stock offered by us will be more fully described in the particular prospectus supplement that will accompany this prospectus, including redemption provisions, rights in the event of our liquidation, dissolution or winding up, voting rights and rights to convert into common stock.

Warrants

We may offer warrants for the purchase of common stock or preferred stock. We may offer warrants independently or together with other securities.

Units

We may offer units comprised of one or more of the other classes of securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully review the risks and uncertainties described under the heading "Risk Factors" contained in the applicable prospectus supplement, and under similar headings in our Annual Report on Form 10-K for the year ended December 31, 2023, as updated by our annual, quarterly and other reports and documents that are incorporated by reference into this prospectus, before deciding whether to purchase any of the securities being registered pursuant to the registration statement of which this prospectus is a part. Each of the risk factors could adversely affect our business, operating results and financial condition, as well as adversely affect the value of an investment in our securities, and the occurrence of any of these risks might cause you to lose all or part of your investment. Additional risks not presently known to us or that we currently believe are immaterial may also significantly impair our business operations.

USE OF PROCEEDS

Unless we state otherwise in the accompanying prospectus supplement, we intend to use the net proceeds from the sale of the securities offered by this prospectus for general corporate purposes. General corporate purposes may include additions to working capital, research and development, financing of capital expenditures, and future acquisitions, collaborations, and strategic investment opportunities. Pending the application of net proceeds, we expect to invest the net proceeds in interest-bearing securities.

We will not receive any of the proceeds in the event the selling stockholders sell common stock.

Capital Stock

The following description of our capital stock is summarized from, and qualified in its entirety by reference to, our certificate of incorporation, as amended, including the certificates of designation, as amended, setting forth the terms of our Preferred Stock.

We urge you to review the following documents because they, and not this summary, define the rights of a holder of shares of common stock and Preferred Stock:

the General Corporation Law of the State of Delaware, or the "DGCL", as it may be amended from time to time;

our certificate of incorporation, as it may be amended or restated from time to time; and

our bylaws, as they may be amended or restated from time to time.

General

As of the date of this prospectus, our authorized capital stock currently consists of 160,000,000 shares, which are divided into two classes consisting of 150,000,000 shares of common stock, par value $0.001 per share, and 10,000,000 shares of preferred stock, par value $0.01 per share.

As of February 29, 2024, there were 2,172,272 shares of common stock outstanding and no shares of preferred stock outstanding. As of February 29, 2024, there are outstanding warrants to purchase 1,970,781 shares of common stock with a weighted average exercise price of $11.81 per share.

Common Stock

Our common stock is listed and traded on the Nasdaq Capital Market under the symbol "GOVX." Holders of our common stock are entitled to one vote for each share held in the election of directors and in all other matters to be voted on by the stockholders. There is no cumulative voting in the election of directors. Holders of common stock are entitled to receive dividends as may be declared from time to time by our Board of Directors out of funds legally available therefor. In the event of liquidation, dissolution or winding up of the Company, holders of common stock are to share in all assets remaining after the payment of liabilities. Holders of common stock have no pre-emptive or conversion rights and are not subject to further calls or assessments. There are no redemption or sinking fund provisions applicable to the common stock. The rights of the holders of the common stock are subject to any rights that may be fixed in the future for holders of preferred stock. All of the outstanding shares of common stock are fully paid and non-assessable.

Undesignated Preferred Stock

Our Board of Directors has the authority to issue up to 10,000,000 shares of preferred stock in one or more series and fix the number of shares constituting any such series, the voting powers, designations, preferences and relative, participating, optional or other special rights and qualifications, limitations or restrictions thereof, including the dividend rights, dividend rate, terms of redemption (including sinking fund provisions), redemption price or prices, conversion rights and liquidation preferences of the shares constituting any series, without any further vote or action by the stockholders. For example, the Board of Directors is authorized to issue preferred stock that would have the right to vote, separately or with any other stockholder of preferred stock, on any proposed amendment to our certificate of incorporation, or on any other proposed corporate action, including business combinations and other transactions. We will not offer preferred stock unless the offering is approved by a majority of our independent directors. The independent directors will have access, at our expense, to our counsel or independent counsel.

The 2020 Warrants

Overview. The 2020 Warrants are listed and traded on the Nasdaq Capital Market under the symbol "GOVXW." The 2020 Warrants were issued in September 2020 pursuant to a Warrant Agent Agreement dated as of September 24, 2020 (the "Warrant Agent Agreement"), between us and American Stock Transfer & Trust Company, LLC, as the warrant agent (the "Warrant Agent") as part of our September 2020 public offering. Certain provisions of the 2020 Warrants are set forth herein but are only a summary and are qualified in their entirety by the relevant provisions of the Warrant Agent Agreement which is filed as an exhibit to the registration statement of which this prospectus is a part.

The 2020 Warrants entitle the registered holder to purchase one share of our common stock at a price equal to $75.00 per share subject to adjustment as discussed below, immediately following the issuance of such warrant and terminating at 5:00 p.m., New York City time, five years from the date of issuance, or September 29, 2025.

Exercisability. The 2020 Warrants are exercisable at any time after their original issuance and at any time up to the date that is five (5) years after their original issuance. The 2020 Warrants may be exercised by delivering a duly executed exercise notice on or prior to the expiration date at the offices of the Warrant Agent, accompanied by full payment of the exercise price, by certified or official bank check payable to the Warrant Agent, for the number of warrants being exercised. Under the terms of the Warrant Agreement, we must use our best efforts to maintain the effectiveness of the related registration statement and current prospectus relating to common stock issuable upon exercise of the 2020 Warrants until the expiration of the warrants. If we fail to maintain the effectiveness of the registration statement and current released prospectus relating to the common stock issuable upon exercise of the 2020 Warrants, the holders shall have the right to exercise them solely via a cashless exercise feature provided for in the 2020 Warrants, until such time as there is an effective registration statement and current prospectus.

8

Exercise Limitation. A holder may not exercise any portion of a September Warrant to the extent that the holder, together with its affiliates and any other person or entity acting as a group, would own more than 4.99% of the outstanding common stock after exercise, as such percentage ownership is determined in accordance with the terms of the warrant, except that upon at least 61 days' prior notice from the holder to us, the holder may waive such limitation up to a percentage not in excess of 9.99%.

Exercise Price. The exercise price per whole share of common stock purchasable upon exercise of the 2020 Warrants is $75.00 per share. The exercise price is subject to adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our common stock and also upon any distributions of assets, including cash, stock or other property to our stockholders. However, the 2020 Warrants will not be adjusted for issuances of common stock at prices below the exercise price.

Fractional Shares. No fractional shares of common stock will be issued upon exercise of the 2020 Warrants. If, upon exercise of the September Warrant, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise, pay a cash adjustment in respect of such fraction in an amount equal to such fraction multiplied by the exercise price. If multiple 2020 Warrants are exercised by the holder at the same time, we shall pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the exercise price.

Transferability. Subject to applicable laws, the 2020 Warrants may be offered for sale, sold, transferred or assigned without our consent.

Exchange Listing. Our 2020 Warrants are listed on the Nasdaq Capital Market under the symbol "GOVXW."

Warrant Agent Agreement. The 2020 Warrants are represented only by one or more global warrants deposited with the Warrant Agent, as custodian on behalf of The Depository Trust Company (DTC) and registered in the name of Cede & Co., a nominee of DTC, or as otherwise directed by DTC. The Warrant Agent is Equiniti Trust Company, LLC, 48 Wall Street, New York, NY 10005, telephone (800) 468-9716.

Fundamental Transactions. In the event of a fundamental transaction, as described in the 2020 Warrants and generally including any reorganization, recapitalization or reclassification of our common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of more than 50% of our outstanding common stock, or any person or group becoming the beneficial owner of 50% of the voting power represented by our outstanding common stock, upon any subsequent exercise of the 2020 Warrants, the holders will be entitled to receive the kind and amount of securities, cash or other property that the holders would have received had they exercised the 2020 Warrants immediately prior to such fundamental transaction.

Rights as a Stockholder. The holders of 2020 Warrants do not have the rights or privileges of holders of common stock or any voting rights until they exercise their warrants and receive shares of common stock. After the issuance of shares of common stock upon exercise of the 2020 Warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

Governing Law. The 2020 Warrants and the Warrant Agent Agreement are governed by New York law.

Delaware Anti-Takeover Law

We have elected not to be subject to certain provisions of Delaware law that could make it more difficult to acquire us by means of a tender offer, a proxy contest, open market purchases, removal of incumbent directors and otherwise. These provisions, summarized below, are expected to discourage types of coercive takeover practices and inadequate takeover bids and to encourage persons seeking to acquire control of us to first negotiate with our Board of Directors.

In general, Section 203 of the DGCL prohibits a publicly held Delaware corporation from engaging in various "business combination" transactions with any interested stockholder for a period of three years after the date of the transaction in which the person became an interested stockholder, unless:

the transaction is approved by the corporation's board of directors prior to the date the interested stockholder obtained interested stockholder status;

9

upon consummation of the transaction that resulted in the stockholder's becoming an interested stockholder, the stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding those shares owned by (a) persons who are directors and also officers and (b) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or;

on or subsequent to the date the business combination is approved by the corporation's board of directors and authorized at an annual or special meeting of stockholders by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

A "business combination" is defined to include mergers, asset sales and other transactions resulting in financial benefit to a stockholder. In general, an "interested stockholder" is a person who, together with affiliates and associates, owns or within three years, did own, 15% or more of a corporation's voting stock.

Section 203 applies to Delaware corporations that have a class of voting stock that is listed on a national securities exchange or held of record by more than 2,000 stockholders; provided, however, the restrictions of this statute will not apply to a corporation if:

the corporation's original charter contains a provision expressly electing not to be governed by the statute;

the corporation's board of directors adopts an amendment to the corporation's bylaws within 90 days of the effective date of the statute expressly electing not to be governed by it;

the stockholders of the corporation adopt an amendment to its charter or bylaws expressly electing not to be governed by the statute (so long as such amendment is approved by the affirmative vote of a majority of the shares entitled to vote);

a stockholder becomes an interested stockholder inadvertently and as soon as practicable divests himself of ownership of a sufficient number of shares so that he ceases to be an interested stockholder, and during the three-year period immediately prior to a business combination, would not have been an interested stockholder but for the inadvertent acquisition;

the business combination is proposed prior to the consummation or abandonment of a merger or consolidation, a sale, lease, exchange, mortgage, pledge, transfer or other disposition of assets of the corporation or a proposed tender or exchange offer for 50% or more of the outstanding voting shares of the corporation; or

the business combination is with an interested stockholder who became an interested stockholder at a time when the restrictions contained in the statutes did not apply.

Our certificate of incorporation includes a provision electing not to be governed by Section 203 of the DCGL. Accordingly, our board of directors does not have the power to reject certain business combinations with interested stockholders based on Section 203 of the DCGL.

Transfer Agent, Warrant Agent and Registrar

The transfer agent, warrant agent and registrar for our common stock and 2020 Warrants is Equiniti Trust Company, LLC, 48 Wall Street, New York, NY 10005, telephone (800) 468-9716.

Listing

DISCLOSURE OF COMMISSION POSITION ON
INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

In the event that a claim for indemnification against such liabilities (other than our payment of expenses incurred or paid by a director, officer or controlling person in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, we will, unless in the opinion of our counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by us is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

THE SECURITIES WE MAY OFFER

Common Stock

The Common Stock we may offer is described above in "Description of Securities-Capital Stock - Common Stock".

Preferred Stock

This section describes the general terms of our preferred stock to which any prospectus supplement may relate. A prospectus supplement will describe the terms relating to any preferred stock to be offered by us in greater detail and may provide information that is different from terms described in this prospectus. A copy of our certificate of incorporation, as amended, and of our bylaws, are exhibits to the registration statement of which this prospectus forms a part. See "Description of Securities - Capital Stock - Undesignated Preferred Stocks" for additional information. A certificate of designation or amendment to our certificate of incorporation, as amended, will specify the terms of the preferred stock being offered, and will be filed or incorporated by reference as an exhibit to the registration statement before the preferred stock is issued. The following description of our preferred stock, and any description of the preferred stock in a prospectus supplement may not be complete and is subject to, and qualified in its entirety by reference to, Delaware law and the actual terms and provisions contained in our certificate of incorporation and our bylaws, each as amended from time to time.

Under our certificate of incorporation, as amended, our board of directors is authorized, without action by the stockholders, to issue preferred stock from time to time with such dividend, liquidation, conversion, voting, redemption, sinking fund and other rights and restrictions as it may determine. All shares of any one series of our preferred stock will be identical, except that shares of any one series issued at different times may differ as to the dates from which dividends may be cumulative, as described in the applicable prospectus supplement.

Unless provided in a prospectus supplement, the shares of our preferred stock to be issued will have no preemptive rights. Any prospectus supplement offering our preferred stock will furnish the following information with respect to the preferred stock offered by that prospectus supplement:

the distinctive designation of each series and the number of shares that will constitute the series;

the voting rights, if any, of shares of the series and the terms and conditions of the voting rights;

the dividend rate, if any, on the shares of the series, the dates on which dividends are payable, any restriction, limitation or condition upon the payment of dividends, whether dividends will be cumulative, and the dates from and after which dividends shall accumulate;

the prices at which, and the terms and conditions on which, the shares of the series may be redeemed, if the shares are redeemable;

the terms and conditions of a sinking or purchase fund for the purchase or redemption of shares of the series, if such a fund is provided;

any preferential amount payable upon shares of the series in the event of the liquidation, dissolution or winding up of, or upon the distribution of any of our assets; and

the prices or rates of conversion or exchange at which, and the terms and conditions on which, the shares of the series may be converted or exchanged into other securities, if the shares are convertible or exchangeable.

11

If our Board of Directors decides to issue any shares of preferred stock, that issuance may discourage or make more difficult a merger, tender offer, business combination or proxy contest, assumption of control by a holder of a large block of our securities, or the removal of incumbent management, even if these events were favorable to the interests of stockholders. Our Board of Directors, without stockholder approval, may issue preferred stock with voting and conversion rights and dividend and liquidation preferences that may adversely affect the holders of our other equity or debt securities.

The particular terms of any series of preferred stock, and the transfer agent and registrar for that series, will be described in a prospectus supplement. All preferred stock offered, when issued, will be fully paid and nonassessable. Any material United States federal income tax consequences and other special considerations with respect to any preferred stock offered under this prospectus will also be described in the applicable prospectus supplement.

Warrants

We may issue warrants for the purchase of preferred stock, common stock, or any combination thereof. We may issue warrants independently or together with any other securities offered by any prospectus supplement and may be attached to or separate from the other offered securities. Each series of warrants will be issued under a separate warrant agreement to be entered into by us with a warrant agent. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. Further terms of the warrants and the applicable warrant agreements will be set forth in the applicable prospectus supplement.

The applicable prospectus supplement relating to any particular issue of warrants will describe the terms of the warrants, including, as applicable, the following:

the title of the warrants;

the aggregate number of the warrants;

the price or prices at which the warrants will be issued;

the designation, terms and number of shares of preferred stock or common stock purchasable upon exercise of the warrants;

the designation and terms of the offered securities, if any, with which the warrants are issued and the number of the warrants issued with each offered security;

the date, if any, on and after which the warrants and the related preferred stock or common stock will be separately transferable;

the price at which each share of preferred stock or common stock purchasable upon exercise of the warrants may be purchased;

the date on which the right to exercise the warrants shall commence and the date on which that right shall expire;

the minimum or maximum amount of the warrants which may be exercised at any one time;

information with respect to book-entry procedures, if any;

a discussion of certain U.S. federal income tax considerations; and

any other terms of the warrants, including terms, procedures and limitations relating to the exchange and exercise of the warrants.

We and the warrant agent may amend or supplement the warrant agreement for a series of warrants without the consent of the holders of the warrants issued thereunder to effect changes that are not inconsistent with the provisions of the warrants and that do not materially and adversely affect the interests of the holders of the warrants.

Units

The following description, together with the additional information we include in any applicable prospectus supplement, summarizes the material terms and provisions of the units that we may offer under this prospectus. Units may be offered independently or together with common or preferred stock, and warrants offered by any prospectus supplement, and may be attached to or separate from those securities. While the terms we have summarized below will generally apply to any future units that we may offer under this prospectus, we will describe the particular terms of any series of units that we may offer in more detail in the applicable prospectus supplement. The terms of any units offered under a prospectus supplement may differ from the terms described below.

12

We will incorporate by reference into the registration statement of which this prospectus forms a part the form of unit agreement, including a form of unit certificate, if any, that describes the terms of the series of units we are offering before the issuance of the related series of units. The following summaries of material provisions of the units and the unit agreements are subject to, and qualified in their entirety by reference to, all the provisions of the unit agreement applicable to a particular series of units. We urge you to read the applicable prospectus supplements related to the units that we sell under this prospectus, as well as the complete unit agreements that contain the terms of the units.

We may issue units consisting of one or more shares of common stock or preferred stock, warrants or any combination of such securities. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit.

Additionally, we will describe in the applicable prospectus supplement the terms of the series of units, including the following:

the designation and terms of the units and the securities included in the units;

any provision for the issuance, payment, settlement, transfer or exchange of the units;

the date, if any, on and after which the securities included in the units may be transferable separately;

whether we will apply to have the units traded on a securities exchange or securities quotation system;

any material United States federal income tax consequences; and

how, for United States federal income tax purposes, the purchase price paid for the units is to be allocated among the component securities.

DILUTION

We will set forth in a prospectus supplement the following information regarding any material dilution of the equity interests of investors purchasing securities in an offering under this prospectus:

the net tangible book value per share of our equity securities before and after the offering;

the amount of the increase in such net tangible book value per share attributable to the cash payments made by purchasers in the offering; and

the amount of the immediate dilution from the public offering price which will be absorbed by such purchasers.

PLAN OF DISTRIBUTION

We or any selling stockholder may sell the securities offered by this prospectus in the manner described below.

By the Company

We may sell the securities from time to time pursuant to underwritten public offerings, direct sales to the public, negotiated transactions, block trades or a combination of these methods. We may sell the securities to or through underwriters or dealers, through agents, directly to one or more purchasers, or through any combination of these methods. The distribution of the securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, at market prices prevailing at the time of sale, at prices related to the prevailing market prices or at negotiated prices.

A prospectus supplement or supplements (and any related free writing prospectus that we may authorize to be provided to you) will describe the terms of the offering of the securities, including, to the extent applicable:

the name or names of any underwriters or dealers, if any;

the purchase price of the securities and the proceeds we will receive from the sale;

any over-allotment options under which underwriters may purchase additional securities from us;

any agency fees or underwriting discounts and other items constituting agents' or underwriters' compensation;

any public offering price;

any discounts or concessions allowed or reallowed or paid to dealers; and

any securities exchange or market on which the securities may be listed.

13

Only underwriters named in the prospectus supplement are underwriters of the securities offered by the prospectus supplement. Underwriters, dealers and agents that participate in the distribution of the securities may be underwriters as defined in the applicable securities laws and any discounts or commissions they receive from us and any profit on their resale of the securities may be treated as underwriting discounts and commissions under the applicable securities laws. We will identify in the applicable prospectus supplement any underwriters, dealers or agents and will describe their compensation. We may have agreements with the underwriters, dealers and agents to indemnify them against specified civil liabilities, including liabilities under the applicable securities laws

By Underwriters. If underwriters are used in the sale, they will acquire the securities for their own account and may resell the securities from time to time in one or more transactions at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable underwriting agreement. We may offer the securities to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Subject to certain conditions, the underwriters will be obligated to purchase all of the securities offered by the prospectus supplement. Any public offering price and any discounts or concessions allowed or reallowed may change from time to time. We may use underwriters with whom we have a material relationship. We will describe in the prospectus supplement, naming the underwriter, the nature of any such relationship.

During and after an offering through underwriters, the underwriters may purchase and sell the securities in the open market. These transactions may include overallotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. The underwriters may also impose a penalty bid, which means that selling concessions allowed to syndicate members or other broker-dealers for the offered securities sold for their account may be reclaimed by the syndicate if the offered securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the offered securities, which may be higher than the price that might otherwise prevail in the open market. If commenced, the underwriters may discontinue these activities at any time

By Dealers. If a dealer is utilized in the sale of any securities offered by this prospectus, we will sell those securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale. We will set forth the names of the dealers and the terms of the transaction in the applicable prospectus supplement.

LEGAL MATTERS

The validity of any securities offered by this prospectus will be passed upon for us by Womble Bond Dickinson (US) LLP.
