Annual Report for Fiscal Year Ending 12-31, 2025 (Form 10-K)

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read together with our consolidated financial statements and the related notes beginning on page F-1. This discussion contains forward-looking statements that involve risks and uncertainties because they are based on current expectations and relate to future events and our future financial performance. Our actual results may differ materially from those anticipated in these forward-looking statements because of many important factors, including those set forth under "Risk Factors" and elsewhere in this Annual Report.

Overview and Recent Developments

GeoVax is a clinical-stage biotechnology company developing human vaccines and immunotherapies against infectious diseases and cancers using novel proprietary platforms.

GeoVax's primary near-term strategic development priority is GEO-MVA, an MVA-based vaccine candidate for mpox and smallpox. GEO-MVA is being advanced on an expedited regulatory pathway in Europe and. is intended to address a documented global supply constraint for orthopoxvirus vaccines. The Company believes GEO-MVA is well-positioned to support both civilian public health needs and broader preparedness and biodefense objectives. The advancement of GEO-MVA represents the Company's most near-term opportunity to achieve regulatory approval and potential commercialization. The program is advancing under an expedited regulatory pathway, with plans to initiate a pivotal Phase 3 clinical trial in the second half of 2026, to address critical global needs for expanded orthopoxvirus vaccine supply and biodefense preparedness.

The Company's lead clinical program in oncology is Gedeptin®, a novel oncolytic solid tumor gene-directed therapy, which recently completed a multicenter Phase 1/2 clinical trial for advanced head and neck cancers. A Phase 2 clinical trial evaluating Gedeptin in combination with an ICI as first-line treatment of patients with squamous cell head and neck cancer eligible for curative surgery, is planned for the first half of 2027.

The Company is also developing GEO-CM04S1, a next-generation COVID-19 vaccine which is currently being evaluated in two Phase 2 clinical trials: (i) as a primary vaccine for immunocompromised patients, including those with hematologic malignancies and other patient populations for whom the currently authorized COVID-19 vaccines are inadequate and (ii) as a booster vaccine in patients with CLL, where an interim DSMB review demonstrated superior immune responses versus an mRNA vaccine. An additional clinical trial evaluating GEO-CM04S1 as more robust booster vaccine in healthy adults who previously received an mRNA vaccine has completed enrollment, with data readouts anticipated in the first half of 2026.

Our corporate strategy is to advance, protect, and strategically leverage our proprietary vaccine and immunotherapy platforms to develop differentiated preventive and therapeutic solutions for infectious diseases and solid tumors. We aim to efficiently progress our product candidates through clinical development and pursue regulatory approval and commercialization through internal development and selective external licensing and partnership arrangements. We also work collaboratively with academic, governmental, and industry partners to validate our technologies, support development efforts and enhance the strategic value of our pipeline.

Our programs are in various stages of development. Key updates for our lead programs are outlined below:

GEO-MVA - mpox/smallpox Vaccine Candidate:

o

GEO-MVA is a MVA vaccine candidate intended for protection against mpox and smallpox. MVA is the strain recommended by both the World Health Organization (WHO) and CDC for these indications and is currently used in the U.S. Strategic National Stockpile.

o

Following scientific advice from the EMA, in May 2025, we intend to proceed directly to a Phase 3 trial, bypassing traditional Phase 1 and 2 studies, subject to final protocol and regulatory alignment. The Phase 3 study is expected to initiate in late 2026.

o

A cGMP clinical drug substance batch of GEO-MVA has been successfully produced to support clinical development.

Gedeptin® -- Gene-Directed Enzyme Prodrug Therapy (GDEPT):

o

Gedeptin has successfully completed a Phase 1/2 clinical trial (NCT03754933) in patients with advanced HNSCC. This trial was funded in part by the FDA pursuant to its Orphan Products Clinical Trials Grants Program.

o

Planning activities are underway for a Phase 2 trial to evaluate the addition of intra-tumoral Gedeptin and intravenous fludarabine to recently approved neoadjuvant pembrolizumab as first-line treatment of patients with head and neck squamous cell carcinoma eligible for curative surgery. Trial initiation is targeted for initiation in 2027.

GEO-CM04S1 - COVID-19 Vaccine Candidate:

o

GEO-CM04S1 is undergoing multiple Phase 2 clinical studies:

One trial (ClinicalTrials.gov Identifier: NCT04977024) is evaluating its use in immunocompromised patients with hematologic malignancies (e.g., following stem cell transplant or CAR-T therapy). Published data from this study's safety lead-in showed GEO-CM04S1 induced both neutralizing antibody and T cell responses in this high-risk population.

A second trial (NCT04639466) is assessing GEO-CM04S1 as a heterologous booster following primary mRNA vaccination. Interim results have shown statistically significant increases in neutralizing antibodies across multiple SARS-CoV-2 variants, including Omicron XBB 1.5.

A third, investigator-initiated trial (NCT05672355) is evaluating GEO-CM04S1 versus an mRNA-based vaccine in patients with chronic lymphocytic leukemia (CLL). The mRNA vaccine arm was discontinued following an interim safety and efficacy review; the GEO-CM04S1 arm continues.

o

In June 2024, GeoVax received a development award through the Rapid Response Partnership Vehicle (RRPV), funded by the Biomedical Advanced Research and Development Authority (BARDA), to support advancement of GEO-CM04S1 into a Phase 2b study. The award was formalized through an agreement with Advanced Technology International (ATI), the RRPV's consortium management firm (the "ATI-RRPV Contract"). On April 11, 2025, we received formal notice from ATI that BARDA elected to terminate the ATI-RRPV Contract for convenience, consistent with its terms.

Manufacturing Platform - Continuous Avian Cell Line:

o

GeoVax is developing a continuous avian cell line manufacturing platform for production of its MVA-based vaccines. This platform will enable scalable, high-yield production of vaccine candidates under current cGMP conditions. Thus far, initial process development steps in support of cGMP production of GEO-MVA in the continuous avian cell line have been achieved Unlike traditional egg-based production methods, continuous cell line manufacturing offers greater efficiency, reproducibility and flexibility, supporting rapid response capabilities for emerging infectious diseases and biothreats. This approach is aligned with U.S. and international priorities for modernizing vaccine manufacturing and ensuring supply chain resilience

Financial Overview

Revenue

Our revenues to date have been related to government grants and contracts and other collaborative arrangements in support of our product development activities. We have not generated any revenue to date from the sale of the products we are developing. 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.

Research and development expenses

Since our inception, we have focused and we continue to focus significant resources on our research and development activities, including developing our vector platform and analytical testing methods, conducting preclinical studies, developing manufacturing processes, and conducting clinical trials. Research and development costs are expensed as incurred and consist primarily of the following:

personnel costs in our research and development functions, including salaries, benefits and stock-based compensation;

expenses incurred under agreements with CROs, for the conduct of clinical trials;

expenses incurred under agreements with contract manufacturing organizations (CMOs) that manufacture product used in clinical trials;

expenses incurred in procuring materials and for analytical and release testing services required to produce vaccine candidates used in clinical trials;

process development expenses to improve the efficiency and yield of the bulk vaccine;

laboratory supplies, vendor expenses and other third-party contract expenses related to preclinical research activities;

technology license fees;

consultant expenses for services supporting our clinical, regulatory and manufacturing activities; and

facilities, depreciation and other general overhead expenses.

We expect our research and development expenditures to increase as we advance our existing and future product candidates into and through clinical trials and pursue regulatory approval, especially with regard to the ongoing and planned GEO-CM04S1, Gedeptin and GEO-MVA clinical programs. We do not provide forward-looking estimates of costs and time to complete our research programs due to the many uncertainties associated with biotechnology research and development. Due to these uncertainties, our future expenditures are likely to be highly volatile in future periods depending on the outcomes of the trials and studies. As we obtain data from preclinical studies and clinical trials, we may elect to discontinue or delay certain development programs to focus our resources on more promising product candidates. Completion of preclinical studies and human clinical trials may take several years or more, but the length of time can vary substantially depending upon several factors. The duration and the cost of future clinical trials may vary significantly over the life of the project because of differences arising during development of the human clinical trial protocols, including the length of time required to enroll suitable patient subjects, the number of patients that ultimately participate in the clinical trial, the duration of patient follow-up, and the number of clinical sites included in the clinical trials.

General and administrative expenses

Our general and administrative expenses consist primarily of personnel costs in our executive, finance, business development and other administrative functions, including stock-based compensation. Other general and administrative expenses include consulting fees, professional service fees for accounting and legal services, lease expenses related to our offices, insurance premiums, intellectual property costs incurred in connection with filing and prosecuting patent applications, depreciation and other costs. We expect our general and administrative expenses will increase in the future as we support expanded research and development activities, prepare for potential commercialization of our current and future product candidates, maintain compliance with requirements of Nasdaq and the SEC, and other general corporate activities.

Critical Accounting Policies and Estimates

This discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, management evaluates its estimates and adjusts them as necessary. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions.

Our significant accounting policies are summarized in Note 2 to our consolidated financial statements for the year ended December 31, 2025, which are included in this Annual Report. We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements:

Revenue Recognition

We recognize revenue in accordance with FASB Accounting Standards Update 2014-09, Revenue from Contracts with Customers (ASU 2014-09), which created a new Topic, Accounting Standards Codification Topic 606. The standard is principle-based and provides a five-step model to determine when and how revenue is recognized. The core principle is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

We have received payments from government entities under non-refundable grants in support of our vaccine development programs. We record revenue associated with these grants when the reimbursable costs are incurred and we have complied with all conditions necessary to receive the grant funds. From time to time, we may enter into collaborative research and development agreements for specific vaccine development approaches and/or disease indications whereby we receive third-party funding for preclinical research under certain of these arrangements. Each agreement is evaluated in accordance with the process defined by ASU 2014-09 and revenue is recognized accordingly.

Stock-Based Compensation

We account for stock-based transactions in which the Company receives services from employees, directors or others in exchange for equity instruments based on the fair value of the award at the grant date. Stock-based compensation cost for awards of common stock is estimated based on the price of the underlying common stock on the date of issuance. Stock-based compensation cost for stock options or warrants is estimated at the grant date based on each instrument's fair value as calculated by using the Black-Scholes option pricing model. We recognize stock-based compensation cost as expense ratably on a straight-line basis over the requisite service period for the award. See Note 6 to our consolidated financial statements for the year ended December 31, 2025 for additional stock-based compensation information.

Research and Development Expense

Research and development costs are charged to expense as incurred and consist of costs incurred in the discovery, development, testing and manufacturing of our product candidates. These expenses consist primarily of (i) salaries, benefits, and stock-based compensation for personnel, (ii) laboratory supplies and facility-related expenses to conduct development, (iii) fees paid to third-party service providers to perform, monitor and accumulate data related to our preclinical studies and clinical trials, (iv) costs related to sponsored research agreements, (v) costs to procure and manufacture materials used in clinical trials, and (vi) license fees and other expenses associated with technology license agreements.

The Company accrues for estimated costs of research and development activities conducted by third-party service providers, which may include the conduct of preclinical studies and clinical trials, and contract manufacturing activities. When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the studies or trials, including clinical trial participant enrollment, completion of events, invoices received and other events. Advance payments for research and development activities are deferred and included in prepaid expenses and other assets. The deferred amounts are expensed as the related goods are delivered or the services are performed.

Funding Requirements and Sources of Capital

To date, we have not generated any product revenue. We do not know when, or if, we will generate any product revenue and we do not expect to generate significant product revenue unless and until we obtain regulatory approval and commercialize one of our current or future product candidates. We anticipate that we will continue to generate losses for the foreseeable future, and we expect the losses to increase as we continue the development of, and seek regulatory approvals for, our product candidates, and begin to commercialize any approved products. We are subject to all of the risks incident to the development of new products, and may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may harm our business. We anticipate that we will need substantial additional funding in connection with our continuing operations. We have funded our operations to date primarily from sales of our equity securities and from government grants and clinical trial assistance.

On March 25, 2025, we closed a registered direct offering of our common stock and warrants. Net proceeds after deducting placement agent fees and expenses and other offering expenses were approximately $4.1 million. During the first quarter of 2025, we also sold shares of our common stock pursuant to the ATM Program for net proceeds of approximately $3.8 million.

On July 2, 2025, we closed a public offering of our common stock and warrants. Net proceeds after deducting placement agent fees and expenses and other offering expenses were approximately $5.5 million. On September 30, 2025, we closed a registered direct offering of our common stock and warrants. Net proceeds after deducting placement agent fees and other offering expenses were approximately $2.3 million. During the third quarter of 2025, we also sold shares of our common stock pursuant to the ATM Program for net proceeds of approximately $220,000.

On December 22, 2025, we closed a public offering of our common stock and warrants. Net proceeds after deducting placement agent fees and expenses and other offering expenses were approximately $3.0 million. During the fourth quarter of 2025, we also sold shares of our common stock pursuant to the ATM Program for net proceeds of approximately $71,000.

On February 17, 2026, we closed a registered direct offering of our common stock and warrants. Net proceeds after deducting placement agent fees and other offering expenses were approximately $885,000.

On March 31, 2026, entered into warrant exercise inducement letters with the holders of certain existing warrants whereby the holders agreed to exercise warrants at a reduced exercise price. Net proceeds to us after deducting placement agent commissions and other offering expenses were approximately $763,000.

During the first quarter of 2026, we also sold shares of our common stock pursuant to the ATM Program for net proceeds of approximately $71,000.

As of the date of this Annual Report, we believe that our existing cash and cash equivalents are sufficient to fund our operations into mid-second quarter of 2026. We plan to pursue additional cash resources through public or private equity or debt financings, government grants/contracts, arrangements with strategic partners, or from other sources.

There can be no assurance that necessary funding will be available on favorable terms or at all. These factors collectively raise substantial doubt about the Company's ability to continue as a going concern. Management believes that we will be successful in securing the additional capital required to continue the Company's planned operations, but that our plans do not fully alleviate the substantial doubt about the Company's ability to operate as a going concern.

We will need to continue to raise additional capital to support our future operating activities, including progression of our development programs, preparation for commercialization, and other operating costs. We may fund a significant portion of our ongoing operations through partnering and collaboration agreements which, while reducing our risks and extending our cash runway, would also reduce our share of eventual revenues, if any, from our vaccine candidates. Additionally, we may be able to fund certain activities with assistance from government programs.

The sale of additional equity would result in additional dilution to our stockholders. We may also fund our operations through debt financing, which would result in debt service obligations, and the instruments governing such debt could provide for operating and financing covenants that would restrict our operations. If we are unable to raise additional capital in sufficient amounts or on acceptable terms, we may be required to delay, limit, reduce, or terminate our product development or future commercialization efforts or grant rights to develop and market vaccine candidates that we would otherwise prefer to develop and market ourselves. Any of these actions could harm our business, results of operations and prospects.

Our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties and is based on assumptions that may prove to be wrong; actual results could vary materially. Our projection takes into consideration contractual commitments we have made, and expect to make, in the normal course of operating our business, which include (i) obligations to our employees, (ii) our lease obligations, (iii) payments due under license agreements for various technologies and patent rights associated with our product development activities, (iv) arrangements with CROs, CMOs, and other third-party vendors for clinical trials services and production of materials for use in our clinical trials, and (v) other various firm purchase commitments and contractual obligations related to production and testing of our product candidates and the general operation of our business.

We have based our projections of operating capital requirements on assumptions that may prove to be incorrect, and we may use our available capital resources sooner than we expect. Our future capital requirements will depend on many factors, which include but are not limited to:

the timing and costs of our ongoing and planned clinical trials;

the timing and costs of manufacturing material for use in clinical trials;

the number and scope of our research programs and the speed at which they are advanced;

the progress and success of our preclinical and clinical development activities;

the costs involved in prosecuting and enforcing patent claims and other intellectual property rights;

the costs to attract and retain skilled personnel;

the costs to maintain and expand our infrastructure to support our operations, our product development, and planned future commercialization efforts;

the terms and timing of establishing and maintaining collaborations, licenses and other similar arrangements;

the costs associated with any products or technologies that we may in-license or acquire; and

the costs and timing of regulatory approvals.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements that are likely or reasonably likely to have a material effect on our financial condition or results of operations.
