1. Description of Business

GeoVax Labs, Inc. (“GeoVax” or the “Company”), is a clinical-stage biotechnology company developing immunotherapies and vaccines against infectious diseases and cancers using a novel vector vaccine platform (Modified Vaccinia Ankara (MVA) Virus-Like Particle, or “GV-MVA-VLP^TM”). In this platform, MVA, a large virus capable of carrying several vaccine antigens, expresses proteins that assemble into highly effective VLP immunogens in the person being vaccinated. The MVA-VLP virus replicates to high titers in approved avian cells for manufacturing but cannot productively replicate in mammalian cells. Therefore, the MVA-VLP derived vaccines can elicit durable immune responses in the host similar to a live attenuated virus, while providing the safety characteristics of a replication-defective vector.

Our current development programs are focused on preventive vaccines against novel coronavirus (COVID-19), Human Immunodeficiency Virus (HIV), Zika Virus, hemorrhagic fever viruses (Ebola, Sudan, Marburg, Lassa), and malaria, as well as immunotherapies for HIV and solid tumor cancers.

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

Certain of our vaccine development activities have been, and continue to be, financially supported by the U.S. Government. This support has been both in the form of research grants and contracts awarded directly to us, as well as indirect support for the conduct of preclinical animal studies and human clinical trials.

We operate in a highly regulated and competitive environment. The manufacturing and marketing of pharmaceutical products require approval from, and are subject to, ongoing oversight by the Food and Drug Administration (FDA) in the United States, by the European Medicines Agency (EMA) in the European Union, and by comparable agencies in other countries. Obtaining approval for a new pharmaceutical product is never certain, may take many years and often involves expenditure of substantial resources. Our goal is to build a profitable company by generating income from products we develop and commercialize, either alone or with one or more potential strategic partners.

GeoVax is incorporated under the laws of the State of Delaware and our principal offices are located in the metropolitan Atlanta, Georgia area.

2. Basis of Presentation

The accompanying condensed consolidated financial statements at March 31, 2021 and for the three-month periods ended March 31, 2021 and 2020 are unaudited, but include all adjustments, consisting of normal recurring entries, which we believe to be necessary for a fair presentation of the dates and periods presented. Interim results are not necessarily indicative of results for a full year. The financial statements should be read in conjunction with our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020. We expect our operating results to fluctuate for the foreseeable future; therefore, period-to-period comparisons should not be relied upon as predictive of the results in future periods.

We enacted reverse stock splits of our common stock on September 25, 2020 (1-for-20) and on January 21, 2020 (1-for-2,000).  The accompanying financial statements, and all share and per share information contained herein, have been retroactively restated to reflect the reverse stock splits.

Our financial statements have been prepared assuming that we will continue as a going concern, which contemplates realization of assets and the satisfaction of liabilities in the normal course of business for the twelve-month period following the issue date of these consolidated financial statements. We are devoting substantially all of our present efforts to research and development of our vaccine and immunotherapy candidates. We have funded our activities to date from government grants and clinical trial assistance, corporate and academic collaborations, and from sales of our equity securities. We believe that our existing cash resources together with current government funding commitments, will be sufficient to continue our planned operations into 2023.

5

We expect to incur future net losses and require substantial funds as we continue our research and development activities. Our transition to profitability will be dependent upon, among other things, the successful development and commercialization of our product candidates. We may never achieve profitability or positive cash flows, and unless and until we do, we will continue to need to raise additional funding. We intend to fund future operations through additional private and/or public offerings of debt or equity securities. In addition, we may seek additional capital through arrangements with strategic partners or from other sources. There can be no assurance that we will be able to raise additional funds or achieve or sustain profitability or positive cash flows from operations. 

3. Significant Accounting Policies and Recent Accounting Pronouncements

We disclosed in Note 2 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020 those accounting policies that we consider significant in determining our results of operations and financial position. During the three months ended March 31, 2021, there have been no material changes to, or in the application of, the accounting policies previously identified and described in the Form 10-K, and there have been no other recent accounting pronouncements or changes in accounting pronouncements which we expect to have a material impact on our financial statements.

4. Basic and Diluted Loss Per Common Share

Basic and diluted loss per common share are computed based on the weighted average number of common shares outstanding. Common share equivalents consist of common shares issuable upon conversion of convertible preferred stock, and upon exercise of stock options and stock purchase warrants. All common share equivalents are excluded from the computation of diluted loss per share since the effect would be anti-dilutive. The weighted average number of common share equivalents which were excluded from the computation of diluted loss per share, totaled 3,055,097 and 48,529 shares at March 31, 2021 and 2020, respectively.

5. Property and Equipment

7. Notes Payable

GRA Note – On February 28, 2018, we entered into a Senior Note Purchase Agreement with Georgia Research Alliance, Inc. (GRA) pursuant to which we issued a five-year Senior Promissory Note (the “GRA Note”) to GRA in exchange for $50,000. The GRA Note bears an annual interest rate of 5%. Future principal repayments are expected to be $9,423 for the remainder of 2021, $13,126 in 2022, and $2,252 in 2023. Interest expense related to the GRA Note for the three-month periods ended March 31, 2021 and 2020 was $336 and $485, respectively.

6

CARES Act Paycheck Protection Program Loan – On April 17, 2020, we received a $170,200 bank loan backed by the United States Small Business Administration pursuant to the Paycheck Protection Program (PPP) provisions of the Coronavirus Aid, Relief, and Economic Security (CARES) Act. The loan bears an annual interest rate of one percent and is due April 17, 2022. We have accrued interest payable associated with the PPP Loan of $1,623. In October 2020, we applied to the lender to have the loan forgiven, based upon our submission of qualifying information regarding eligible expenses; as of the date of this report our forgiveness application has not been processed. Interest expense related to the PPP Loan for the three-month periods ended March 31, 2021 and 2020 was $420 and $-0-, respectively.

8. Commitments

Lease Agreement

We lease approximately 8,400 square feet of office and laboratory space pursuant to an operating lease which expires on December 31, 2022. Rent expense for the three-month periods ended March 31, 2021 and 2020 was $42,803 and $41,539, respectively. Future minimum lease payments total $128,410 for the remainder of 2021 and $176,356 in 2022, although the lease may be terminated at any time by either party with ninety days written notice.

Other Commitments

In the normal course of business, we enter into various firm purchase commitments related to production and testing of our vaccine, conduct of research studies, and other activities. As of March 31, 2021, there are approximately $800,000 of unrecorded outstanding purchase commitments to our vendors and subcontractors, all of which we expect will be due in 2021. We expect $211,326 of this amount to be reimbursable to us pursuant to existing government grants.

9. Stockholders’ Equity

Public Offering – On February 11, 2021, we closed an underwritten bought deal public offering of 1,644,000 shares of our common stock, including 204,000 shares sold pursuant to the full exercise of the underwriter’s option to purchase additional shares, at a price to the public of $6.25 per share. Net proceeds after deducting underwriting discounts and commissions and other offering expenses were approximately $9.4 million. Additionally, we issued to the underwriter, as a portion of the underwriting compensation, warrants to purchase up to a total of 72,000 shares of our common stock. The shares subject to the underwriter’s warrant agreement are exercisable at $6.875 per share, are initially exercisable 180 days after the effective date of the offering and have a term of three years from their initial exercise date.

Stock Options – We have a stock-based incentive plan (the “2020 Plan”) pursuant to which our Board of Directors may grant stock options and other stock-based awards to our employees, directors and consultants. A total of 1,000,000 shares of our common stock are reserved for issuance pursuant to the 2020 Plan. During the three-months ended March 31, 2021, there were no transactions related to the 2020 Plan. As of March 31, 2021, there were 602,000 stock options outstanding, with a weighted-average exercise price of $2.79 per share and a weighted-average remaining term of 9.7 years.

Stock Purchase Warrants – During the three months ended March 31, 2021, 188,688 stock purchase warrants were exercised on a “cashless” basis, resulting in the issuance of 145,866 shares of our common stock, and 690,034 stock purchase warrants were exercised for cash, resulting in the issuance of 690,034 shares of our common stock for net proceeds to us of $3,174,156. As of March 31, 2021, there are 2,793,635 stock purchase warrants outstanding, with a weighted-average exercise price of $5.07 per share and a weighted-average remaining term of 4.4 years.

Other Common Stock Transactions – During the three months ended March 31, 2021, we issued 1,472 shares of our common stock pursuant to a consulting agreement for which we recognized $6,000 of stock-based compensation expense.

10. Stock-Based Compensation Expense

Stock-based compensation expense related to our stock option plan was $56,190 and $-0- during the three-month periods ended March 31, 2021 and 2020, respectively. Stock-based compensation expense related to stock options is recognized on a straight-line basis over the requisite service period for the award and is allocated to research and development expense or general and administrative expense based upon the related employee classification. As of March 31, 2021, there is $599,320 of unrecognized compensation expense that is expected to be recognized over a weighted-average period of 2.7 years.

7

Additionally, during the three-month periods ended March 31, 2021 and 2020 we recorded stock-based compensation expense of $20,600 and $6,000, respectively, associated with common stock issued for consulting and financial advisory services. As of March 31, 2021, there is $34,067 recorded as a prepaid expense for one of these arrangements, which will be recognized as expense during 2021 over the term of the related agreement.

11. Income Taxes

Because of our historically significant net operating losses, we have not paid income taxes since inception. We maintain deferred tax assets that reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. These deferred tax assets are comprised primarily of net operating loss carryforwards and also include amounts relating to nonqualified stock options and research and development credits. The net deferred tax asset has been fully offset by a valuation allowance because of the uncertainty of our future profitability and our ability to utilize the deferred tax assets. Utilization of operating losses and credits will be subject to substantial annual limitations due to ownership change provisions of Section 382 of the Internal Revenue Code. The annual limitation will result in the expiration of net operating losses and credits before utilization.

12. Grants and Collaboration Revenue

We receive payments from government entities under grants from the National Institute of Allergy and Infectious Diseases (NIAID) and from the U.S. Department of Defense in support of our vaccine research and development efforts. We record revenue associated with government grants as the reimbursable costs are incurred. During the three-month periods ended March 31, 2021 and 2020, we recorded $110,417 and $654,021, respectively, of revenues associated with these grants. During the three-month period ended March 31, 2020, we also recorded $61,956 of revenue associated with a research collaboration agreement with Leidos, Inc. As of March 31, 2021, there is an aggregate of $355,010 in approved grant funds available for use during 2021.

FORWARD LOOKING STATEMENTS

In addition to historical information, the information included in this Form 10-Q contains forward-looking statements. Forward-looking statements involve numerous risks and uncertainties, including but not limited to the risk factors set forth under the heading “Risk Factors” in the Annual Report on Form 10-K for the year ended December 31, 2020, and should not be relied upon as predictions of future events. Certain such forward-looking statements can be identified by the use of forward-looking terminology such as ‘‘believes,’’ ‘‘expects,’’ ‘‘may,’’ ‘‘will,’’ ‘‘should,’’ ‘‘seeks,’’ ‘‘approximately,” ‘‘intends,’’ ‘‘plans,’’ ‘‘pro forma,’’ ‘‘estimates,’’ or ‘‘anticipates’’ or other variations thereof or comparable terminology, or by discussions of strategy, plans, or intentions. Such forward-looking statements are necessarily dependent on assumptions, data, or methods that may be incorrect or imprecise and may be incapable of being realized. The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in the forward-looking statements:

● whether we can raise additional capital as and when we need it;

● whether we are successful in developing our products;

● whether we are able to obtain regulatory approvals in the United States and other countries for sale of our products;

● whether we can compete successfully with others in our market; and

● whether we are adversely affected in our efforts to raise cash by the volatility and disruption of local and national economic, credit and capital markets and the economy in general.

Readers are cautioned not to place undue reliance on forward-looking statements, which reflect our management’s analysis only. We assume no obligation to update forward-looking statements.

Overview

GeoVax is a clinical-stage biotechnology company developing immunotherapies and vaccines against cancers and infectious diseases using a novel vector vaccine platform (Modified Vaccinia Ankara-Virus Like Particle or “GV-MVA-VLP™”). During 2020, we began a program to develop a vaccine for prevention of novel coronavirus (COVID-19) infection. That effort has resulted in four COVID-19 vaccine candidates. These COVID-19 vaccine candidates have been designed and constructed and are being tested using relevant experimental animal challenge models. Additional development programs are focused on preventive and therapeutic vaccines against Human Immunodeficiency Virus (HIV); preventive vaccines against hemorrhagic fever viruses (Ebola, Sudan, Marburg, and Lassa fever), Zika virus and malaria; as well as immunotherapies for solid tumor cancers.

8

For our infectious disease vaccines, our recombinant MVA vector expresses target proteins on highly immunogenic VLPs in the person being vaccinated, with the intended result of producing durable immune responses with the safety characteristics of the replication deficient MVA vector and cost-effective manufacturing.

In cancer immunotherapy, we believe that stimulating the immune system to treat or prevent cancers is a compelling concept and that the opportunity for immune-activating technologies is promising, especially in light of advancements such as checkpoint inhibitors leading the way in oncology. Despite drug approvals in limited indications and promising results in clinical trials, there remains a significant need and opportunity for further advancements. We believe our GV-MVA-VLP™ platform is well-suited for delivery of tumor-associated antigens and we plan to pursue development of our platform in this space.

Our most advanced vaccine program is focused on prevention of the clade B subtype of HIV prevalent in the regions of the Americas, Western Europe, Japan and Australia; our HIV vaccine candidate, GOVX-B11, will be included in an upcoming clinical trial (HVTN 132) managed by the HIV Vaccine Clinical Trials Network (HVTN) with support from the National Institute of Allergy and Infectious Diseases (NIAID) of the National Institutes of Health (NIH), which is targeted to begin in late 2021. Additionally, during August 2020 a consortium led by researchers at the University of California, San Francisco (UCSF) began a clinical trial using our vaccine as part of a combinational therapy to induce remission in HIV-positive individuals. Through the efforts of our collaborator, American Gene Technologies International, Inc. (AGT), we expect that our HIV vaccine will also enter clinical trials during 2021 in combination with AGT’s gene therapy technology to seek a functional cure for HIV. Our other vaccine and immunotherapy programs are at various other stages of development.

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

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.

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 the estimates 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.

For a description of critical accounting policies that affect our significant judgments and estimates used in the preparation of our financial statements, refer to Item 7 in Management’s Discussion and Analysis of Financial Condition and Results of Operations and Note 2 to our Consolidated Financial Statements contained in our Annual Report on Form 10-K for the year ended December 31, 2020. There have been no significant changes to our critical accounting policies from those disclosed in our 2020 Annual Report.

Recent Accounting Pronouncements

Information regarding recent accounting pronouncements is contained in Note 3 to the condensed consolidated financial statements, included in this Quarterly Report.

Liquidity and Capital Resources

Our principal uses of cash are to finance our research and development activities. Since inception, we have funded these activities primarily from government grants and clinical trial assistance, and from sales of our equity and debt securities. At March 31, 2021, we had cash and cash equivalents of $20,842,782 and total assets of $21,115,446, as compared to $9,883,796 and $10,393,899, respectively, at December 31, 2020. At March 31, 2021, we had working capital of $20,509,263, compared to a $9,424,839 at December 31, 2020.

Net cash used in operating activities was $1,621,027 and $358,620 for the three-month periods ended March 31, 2021 and 2020, respectively. Generally, the variances between periods are due to fluctuations in our net losses, offset by non-cash charges such as depreciation and stock-based compensation expense, and by net changes in our assets and liabilities. Our net losses generally fluctuate based on expenditures for our research activities, partially offset by government grant revenues. See “Results of Operations – Grant and Collaboration Revenues” below for additional details concerning our government grants.

NIAID has funded the costs of conducting all of our human clinical trials (Phase 1 and Phase 2a) to date for our preventive HIV vaccines, with GeoVax incurring certain costs associated with manufacturing the clinical vaccine supplies and other study support. We expect that NIAID will also fund the cost of the planned Phase 1 trial (HVTN 132) to further evaluate the safety and immunogenicity of adding “protein boost” components to our vaccine, GOVX-B11. We expect HVTN 132 to commence patient enrollment during 2021. Additionally, we are party to a collaboration with American Gene Technologies International, Inc. (AGT) whereby AGT intends to conduct a Phase 1 human clinical trial with our combined technologies, with the ultimate goal of developing a functional cure for HIV infection. AGT began the Phase 1 trial in late 2020, and we expect the addition of our vaccine into the trial during 2021. A similar effort is underway with a consortium led by researchers at the University of California, San Francisco (UCSF), using our vaccine as part of a combinational therapy to induce remission in HIV-positive individuals; this program entered clinical trials during August 2020. Each of these programs could experience delays as a result of the ongoing COVID-19 pandemic.

Net cash provided by financing activities was $12,580,013 and $297,086 for the three-month periods ended March 31, 2021 and 2020, respectively. Net cash provided by financing activities during the 2021 period relates to (i) net proceeds of $9,408,920 received in February 2021 from the public offering of our common stock (see discussion below), (ii) $3,174,156 of net proceeds from the exercise of warrants, and (iii) $3,063 in principal repayments toward a five-year Senior Promissory Note (the “GRA Note”) to the Georgia Research Alliance, Inc. Net cash provided by financing activities during the 2020 period relates to the sale by us of shares of our Series J convertible preferred stock for net proceeds of $300,000 and $2,914 in principal repayments toward the GRA Note.

Public Offering – On February 11, 2021, we closed an underwritten bought deal public offering of 1,644,000 shares of our common stock, including 204,000 shares sold pursuant to the full exercise of the underwriter’s option to purchase additional shares, at a price to the public of $6.25 per share. Net proceeds after deducting underwriting discounts and commissions and other offering expenses were $9,408,920.

Warrant Exercises – During January and February 2021, holders of our warrants exercised 62,626 Series I Warrants, 126,042 Pre-Funded Warrants and 690,034 Unit Warrants, resulting in the issuance of 835,900 shares of our common stock for aggregate net proceeds to us of $3,174,156.

PPP Loan. On April 17, 2020, we received a $170,200 bank loan backed by the United States Small Business Administration pursuant to the Paycheck Protection Program (PPP) provisions of the CARES Act. The loan bears an annual interest rate of one percent and is due April 17, 2022. In October 2020, we applied to the lender to have the loan forgiven, based upon our submission of qualifying information regarding eligible expenses; as of the date of this report our forgiveness application has not been processed.

As of March 31, 2021, we had an accumulated deficit of approximately $47.4 million. We expect for the foreseeable future we will continue to operate at a loss. The amount of the accumulated deficit will continue to increase, as it will be expensive to continue our research and development efforts. We will continue to require substantial funds to continue our activities and cannot predict the outcome of our efforts. We believe that our existing cash resources, combined with funding from existing government grants and clinical trial support, will be sufficient to fund our planned operations into 2023. We may require additional funds to continue our planned operations beyond that date. We are currently seeking sources of capital through additional government grant programs and clinical trial support, and we plan to conduct additional offerings of our equity securities. Additional funding may not be available on favorable terms or at all and if we fail to obtain additional capital when needed, we may be required to delay, scale back, or eliminate some or all of our research and development programs as well as reduce our general and administrative expenses.

10

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.

Results of Operations

Net Loss

We recorded a net loss of $1,562,778 for the three-month period ended March 31, 2021, as compared to $595,694 for the three-month period ended March 31, 2020. Our net losses typically fluctuate due to the timing of activities and related costs associated with our vaccine research and development activities and our general and administrative costs, as described below.

Grant and Collaboration Revenues

Our grant and collaboration revenues relate to grants and contracts from agencies of the U.S. government and collaborative arrangements with other third parties in support of our vaccine development activities. During the three-month period ended March 31, 2021, we recorded grant and collaboration revenues of $110,417, as compared to $715,977 during the comparable period of 2020. The variance in our grant and collaboration revenues from period to period primarily relates to the timing and amount of the associated expenditures. Additional detail concerning our grant and collaboration revenues and the remaining funds available for use as of March 31, 2021 is presented in the table below.

	Revenues Recorded During Three-Month Periods Ended March 31,				Approved Funds Available at
Description	2021		2020			March 31, 2021
Lassa Fever – U.S. Army Grant	$	-	$	654,021		$	165,500
Covid-19 – NIH SBIR Grant		110,417		-			189,510
Malaria – Leidos, Inc. Collaboration		-		61,956			-
Total	$	110,417	$	715,977		$	355,010

Research and Development Expenses

Our research and development expenses were $602,783 and $808,936 for the three-month periods ended March 31, 2021 and 2020, respectively. Research and development expense for these periods includes stock-based compensation expense of $21,468 and $-0-, respectively (see discussion under “Stock-Based Compensation Expense” below).

Our research and development expenses can fluctuate considerably on a period-to-period basis, depending on the timing of expenditures related to our government grants and other research projects, and other factors. Research and development expenses decreased by $206,153, or 25%, from the 2020 period to 2021 primarily due to the timing of external expenditures related to our government grants. As of March 31, 2021, there is $355,010 in approved grant funds (as shown in the table above), which we expect to expend during the remainder of 2021. We plan to seek additional government grant funding for our development programs, which may increase our research and development expenses in the future, although there can be no assurance any such funds will be obtained.

We do not disclose our research and development expenses by project, since our employees’ time is spread across multiple programs and our laboratory facility is used for multiple vaccine candidates. We track the direct cost of research and development expenses related to government grant revenue by the percentage of assigned employees’ time spent on each grant and other direct costs associated with each grant. Indirect costs associated with grants are not tracked separately but are applied based on a contracted overhead rate negotiated with the NIH. Therefore, the recorded revenues associated with government grants approximate the costs incurred.

11

We expect our research and development costs to increase as we continue development of our various programs and as we move toward later stages of development, especially with regard to clinical trials. We do not provide forward-looking estimates of costs and time to complete our research programs due to the many uncertainties associated with vaccine 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 pre-clinical studies and clinical trials, we may elect to discontinue or delay vaccine development programs to focus our resources on more promising vaccine 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 number of patients that ultimately participate in the clinical trial; the duration of patient follow-up that seems appropriate in view of the results; the number of clinical sites included in the clinical trials; and the length of time required to enroll suitable patient subjects.

General and Administrative Expenses

Our general and administrative expenses were $1,071,710 and $502,345 for the three-month periods ended March 31, 2021 and 2020 respectively. General and administrative costs include officers’ salaries, legal and accounting costs, patent costs, and other general corporate expenses. General and administrative expense includes stock-based compensation expense of $55,322 and $6,000 for the 2021 and 2020 periods, respectively (see discussion under “Stock-Based Compensation Expense” below). Excluding stock-based compensation expense, general and administrative expenses were $1,016,388 and $496,345 for the three-month periods ended March 31, 2021 and 2020, respectively, representing an increase of $520,043 (105%). This increase includes approximately $200,000 related to higher Delaware franchise taxes with the remainder primarily due to higher legal and patent costs, consulting fees, and personnel costs. For the remainder of 2021, we expect our general and administrative expenses to remain reasonably consistent with that of the first quarter. We expect that our general and administrative costs may increase beyond 2021 in support of expanded research and development activities and other general corporate activities.

Stock-Based Compensation Expense

The table below shows the components of stock-based compensation expense for the three-month periods ended March 31, 2021 and 2020. In general, stock-based compensation expense is allocated to research and development expense or general and administrative expense according to the classification of cash compensation paid to the employee, consultant or director to whom the stock compensation was granted.

	Three Months Ended March 31,
	2021		2020
Stock option expense	$	56,190	$	-
Stock issued for services		20,600		6,000
Total stock-based compensation expense	$	76,790	$	6,000

As a result of the reverse stock splits enacted in April 2019 and in January 2020, we made adjustments and retroactive restatements to all of our outstanding stock options such that the balances in January 2020 were negligible. We therefore recorded no stock-based compensation expense related to our stock option plan for the majority of 2020. We re-initiated employee stock option grants in December 2020.

Other Income (Expense)

Interest income for the three-month periods ended March 31, 2021 and 2020 was $2,053 and $752, respectively. The variances between periods are primarily attributable to cash available for investment and interest rate fluctuations.

Interest expense for the three-month periods ended March 31, 2021 and 2020 was $755 and $1,142, respectively, related to the GRA Note, PPP Loan, and financing costs associated with insurance premiums (for the 2020 period only).

Item 3         Quantitative and Qualitative Disclosures About Market Risk

Our exposure to market risk is limited primarily to interest income sensitivity, which is affected by changes in the general level of United States interest rates, particularly because a significant portion of our investments are in institutional money market funds. The primary objective of our investment activities is to preserve principal while at the same time maximizing the income received without significantly increasing risk. Due to the nature of our short-term investments, we believe that we are not subject to any material market risk exposure. We do not have any derivative financial instruments or foreign currency instruments.

Item 4         Controls and Procedures

Evaluation of disclosure controls and procedures

Disclosure controls and procedures are controls and other procedures that are designed to ensure that the information required to be disclosed in reports filed or submitted under the Securities Exchange Act of 1934, as amended (Exchange Act), is (1) recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and (2) accumulated and communicated to management, including the Chief Executive Officer and Principal Financial and Accounting Officer, as appropriate to allow timely decisions regarding required disclosure.

Our management has carried out an evaluation, under the supervision and with the participation of our Principal Executive Officer and our Principal Financial and Accounting Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Exchange Act Rules 13a-15 and 15d-15 as of the end of the period covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this report, our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms.

Changes in internal control over financial reporting

Although we have modified certain of our internal control procedures as a result of the COVID-19 pandemic, there were no significant changes in our internal control over financial reporting that occurred during the three months ended March 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Controls

Management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all error and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected.

Nature of Operations [Text Block]

1. Description of Business

GeoVax Labs, Inc. (“GeoVax” or the “Company”), is a clinical-stage biotechnology company developing immunotherapies and vaccines against infectious diseases and cancers using a novel vector vaccine platform (Modified Vaccinia Ankara (MVA) Virus-Like Particle, or “GV-MVA-VLP

TM

”). In this platform, MVA, a large virus capable of carrying several vaccine antigens, expresses proteins that assemble into highly effective VLP immunogens in the person being vaccinated. The MVA-VLP virus replicates to high titers in approved avian cells for manufacturing but cannot productively replicate in mammalian cells. Therefore, the MVA-VLP derived vaccines can elicit durable immune responses in the host similar to a live attenuated virus, while providing the safety characteristics of a replication-defective vector.

Our current development programs are focused on preventive vaccines against novel coronavirus (COVID-

19

), Human Immunodeficiency Virus (HIV), Zika Virus, hemorrhagic fever viruses (Ebola, Sudan, Marburg, Lassa), and malaria, as well as immunotherapies for HIV and solid tumor cancers.

Our corporate strategy is to advance, protect and exploit our differentiated vaccine immunotherapy platform leading to the successful development of preventive and therapeutic vaccines against infectious diseases and various cancers. With our design and development capabilities, we are progressing and validating an array of cancer and infectious disease immunotherapy and vaccine product candidates. Our goal is to advance products through to human clinical testing, and to seek partnership or licensing arrangements for achieving regulatory approval and commercialization. We also leverage

third

party resources through collaborations and partnerships for preclinical and clinical testing with multiple government, academic and corporate entities.

Certain of our vaccine development activities have been, and continue to be, financially supported by the U.S. Government. This support has been both in the form of research grants and contracts awarded directly to us, as well as indirect support for the conduct of preclinical animal studies and human clinical trials.

We operate in a highly regulated and competitive environment. The manufacturing and marketing of pharmaceutical products require approval from, and are subject to, ongoing oversight by the Food and Drug Administration (FDA) in the United States, by the European Medicines Agency (EMA) in the European Union, and by comparable agencies in other countries. Obtaining approval for a new pharmaceutical product is never certain,

may

take many years and often involves expenditure of substantial resources. Our goal is to build a profitable company by generating income from products we develop and commercialize, either alone or with

one

or more potential strategic partners.

GeoVax is incorporated under the laws of the State of Delaware and our principal offices are located in the metropolitan Atlanta, Georgia area.

2. Basis of Presentation

The accompanying condensed consolidated financial statements at

March 31, 2021

and for the

three

-month periods ended

March 31, 2021

and

2020

are unaudited, but include all adjustments, consisting of normal recurring entries, which we believe to be necessary for a fair presentation of the dates and periods presented. Interim results are

not

necessarily indicative of results for a full year. The financial statements should be read in conjunction with our audited consolidated financial statements included in our Annual Report on Form

10

-K for the year ended

December 31, 2020.

We expect our operating results to fluctuate for the foreseeable future; therefore, period-to-period comparisons should

not

be relied upon as predictive of the results in future periods.

We enacted reverse stock splits of our common stock on

September 25, 2020 (

1

-for-

20

) and on

January 21, 2020 (

1

-for-

2,000

).  The accompanying financial statements, and all share and per share information contained herein, have been retroactively restated to reflect the reverse stock splits.

Our financial statements have been prepared assuming that we will continue as a going concern, which contemplates realization of assets and the satisfaction of liabilities in the normal course of business for the

twelve

-month period following the issue date of these consolidated financial statements. We are devoting substantially all of our present efforts to research and development of our vaccine and immunotherapy candidates. We have funded our activities to date from government grants and clinical trial assistance, corporate and academic collaborations, and from sales of our equity securities. We believe that our existing cash resources together with current government funding commitments, will be sufficient to continue our planned operations into

2023.

We expect to incur future net losses and require substantial funds as we continue our research and development activities. Our transition to profitability will be dependent upon, among other things, the successful development and commercialization of our product candidates. We

may

never achieve profitability or positive cash flows, and unless and until we do, we will continue to need to raise additional funding. We intend to fund future operations through additional private and/or public offerings of debt or equity securities. In addition, we

may

seek additional capital through arrangements with strategic partners or from other sources. There can be

no

assurance that we will be able to raise additional funds or achieve or sustain profitability or positive cash flows from operations.

Basic and diluted loss per common share are computed based on the weighted average number of common shares outstanding. Common share equivalents consist of common shares issuable upon conversion of convertible preferred stock, and upon exercise of stock options and stock purchase warrants. All common share equivalents are excluded from the computation of diluted loss per share since the effect would be anti-dilutive.

11. Income Taxes

Because of our historically significant net operating losses, we have

not

paid income taxes since inception. We maintain deferred tax assets that reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. These deferred tax assets are comprised primarily of net operating loss carryforwards and also include amounts relating to nonqualified stock options and research and development credits. The net deferred tax asset has been fully offset by a valuation allowance because of the uncertainty of our future profitability and our ability to utilize the deferred tax assets. Utilization of operating losses and credits will be subject to substantial annual limitations due to ownership change provisions of Section

382

of the Internal Revenue Code. The annual limitation will result in the expiration of net operating losses and credits before utilization.
