Item 1. Business

Overview

We are a biopharmaceutical company primarily engaged in the development of immune therapies and vaccines. Our gp96 platform is designed to activate the immune system. This platform has broad applications in cancer and infectious disease. Our platform leverages gp96’s role as a natural molecular warning system that presents antigens to the immune system. HS-110 (viagenpumatucel-L) is our first allogeneic (“off-the-shelf”) cell line biologic product candidate in a series of proprietary immunotherapies designed to stimulate a patient’s T-cells to destroy cancer utilizing our gp96 platform. HS-130 is an allogeneic cell line engineered to express the extracellular domain of OX40 ligand fusion protein (OX40L-Fc), a key costimulator of T-cells, with the potential to augment antigen-specific CD4+ T-cell and CD8+ T-cell responses when combined with our gp96 platform. We have also initiated development of a new COVID-19 vaccine program under our Zolovax, Inc. subsidiary (“Zolovax”) that utilizes our gp96 platform to secrete SARS-CoV-2 antigens. We proposed a prototype vaccine directed against eastern equine encephalitis virus (EEEV), a known biothreat to the United States and on the CDC list for needed vaccine therapeutics. Our subsidiary Pelican Therapeutics, Inc. (“Pelican”), is developing PTX-35, a novel T-cell co-stimulator agonist antibody targeting TNFRSF25 for systemic administration.

These programs are designed to harness the body's natural antigen specific immune activation and tolerance mechanisms to reprogram immunity and provide a long-term, durable clinical effect. We have completed recruiting patients in our Phase 2 HS-110 non-small cell lung cancer (NSCLC) trial and are enrolling patients in our Phase 1 clinical trial of HS-130 in combination with HS-110 and in our Phase 1 clinical trial of PTX-35. We are also providing pre-clinical, CMC development, and administrative support for these efforts; while constantly focusing on protecting and expanding our intellectual property in areas of strategic interest. As we advance our clinical programs, we are in close contact with our CROs and clinical sites and are assessing the impact of COVID-19 on our studies, current timelines and costs.

About our gp96 platform

Our gp96 platform, which includes ImPACT ^® and ComPACT ^™, is designed to activate and expand tumor antigen specific “killer” T-cells to destroy a patient’s cancer. By turning immunologically “COLD tumors HOT,” we believe our platform has the potential to become an essential component of the immuno-oncology regimen to enhance the effectiveness and durability of checkpoint inhibitors and other cancer therapies, thereby improving outcomes for those patients less likely to benefit from checkpoint inhibitors alone.

We believe this is a highly differentiated approach as our platform delivers a broad range of tumor antigens that are previously unrecognized by the patient’s immune system. Our gp96 platform combines these tumor antigens with a powerful, naturally occurring immune adjuvant, gp96, to actively chaperone these antigens. Our gp96 product candidates are non-replicating, “off-the-shelf”, allogenic cell-based therapies that are locally administered into the skin. The treatment primes local natural immune recognition to activate T-cells to seek and destroy the cancer cells throughout the body. These gp96 agents can be administered with a variety of immuno-modulators to enhance a patient’s immune response through T-cell activation.

Table of Contents

Unlike many other “patient specific” or autologous immunotherapy approaches, our drugs are fully allogeneic, “off-the-shelf” products which means that we can administer them immediately without the extraction of blood or tumor tissue from each patient or the creation of an individualized treatment based on these patient materials. Our gp96 product candidates are produced from allogeneic cell lines expressing tumor-specific proteins common among cancers. Because each patient receives the same treatment, we believe that our immunotherapy approach offers superior speed to initiation, logistical, manufacturing and importantly, cost benefits, compared to “personalized” precision medicine approaches.

About ImPACT^®

Our gp96 platform is an allogenic cell-based, T-cell-stimulating platform that functions as an immune activator to stimulate and expand T-cells. The key component of this innovative immunotherapy platform is the dual functionality of the heat shock protein, gp96.

As a molecular chaperone, gp96 is typically found within the cell’s endoplasmic reticulum and facilitates the folding of newly synthesized proteins for functionalized tasks. When a cell abnormally dies through necrosis or infection, gp96 is naturally released into the surrounding microenvironment. At this moment, gp96 becomes a Danger Associated Molecular Protein, or “DAMP”, a molecular warning signal for localized innate activation of the immune system. In this context, gp96 serves as a potent adjuvant, or immune stimulator, via Toll-Like Receptor 4/2 (TLR4 and TLR2) signaling which serves to activate professional antigen presenting cells (APCs), such as dendritic cells that upregulate T-cell costimulatory ligands, major histocompatibility (MHC) molecules and immune activating cytokines. It is among the most powerful adjuvants found in the body and uniquely shows exclusive specificity to CD8+ “killer” T-cells through cross-presentation of the gp96-chaperoned tumor associated peptide antigens directly to MHC class I molecules for direct activation and expansion of CD8+ T-cells. Thus, gp96 plays a critical role in the mechanism of action for our T-cell activating platform immuno-therapies; mimicking necrotic cell death and activating a powerful, tumor antigen-specific T-cell immune response to attack the patient’s cancer cells.

About ComPACT^®

Our gp96 platform delivers antigen-driven T-cell activation and specific co-stimulation in a single product by providing

specific co-stimulation to enhance T-cell activation and expansion. This approach has the potential to simplify combination immunotherapy development for oncology patients, as it is designed to deliver the gp96 heat shock protein and a T-cell co-stimulatory fusion protein (OX40L) as a single therapeutic, without the need for multiple, independent biologic products. This dual approach has several potential advantages including: (a) enhanced activation of antigen-specific CD8+ T-cells; (b) boosting the number of antigen-specific CD8+ and CD4+ T-cells compared to OX40L alone; (c) stimulation of T-cell memory function to remain effective after treatment, even if the cancer comes back; (d) demonstration of less toxicity, as the source of cancer associated antigens and co-stimulator are supplied at the same time locally in the draining lymph nodes, which drives targeted, cancer specific immunity towards the tumor rather than throughout the body; and (e) simplification of combination cancer immunotherapy versus systemic co-stimulation with conventional monoclonal antibodies (mAbs).

About COVID-19 Program

Besides its utility in oncology, our gp96 platform has been shown to activate the human immune system to combat infectious diseases. Our collaborators have laid a solid foundation by engineering different pathogenic antigens into our platform. Previous preclinical studies using our gp96 platform includes SIV/HIV, malaria and Zika. We initiated a COVID-19 vaccine program in collaboration with the University of Miami in March 2020.

During the year we commenced preclinical testing of the vaccine under a sponsored research agreement and have continued development of a cell-based vaccine expressing gp96-Ig, OX40L-Ig and SARS-CoV-2 protein. In July 2020, we announced generation of proof-of-concept data demonstrating vaccine immunogenicity in relevant preclinical models, including expansion of human-HLA-restricted T-cells against immunodominant epitopes of SARS-CoV-2 spike protein. In August 2020, we reported preclinical data for our gp96-based COVID-19 vaccine generated at the University of Miami Miller School of Medicine, showing robust T cell mediated immune response directed against the spike protein of SARS-CoV-2. Also in August 2020, we announced publication of positive preclinical COVID-19 vaccine results, which included

supporting data that our gp96-based COVID-19 vaccine induces systemic and tissue-specific (lung) memory CD8+ T cells and tissue-resident memory CD8+ T cells.

The strategy for this program includes providing prophylactic protection to elderly patients and those with underlying health conditions and driving a cellular immune response via CD8+ T cells, in addition to a humoral immune response. We have submitted grant applications to fund and accelerate COVID-19 vaccine development; however, there can be no assurance that our grant application will be approved and if approved, the amount of funding that we will receive.

About PTX-35

Pelican is focused on developing an agonist mAb, PTX-35, against a T-cell costimulatory receptor, TNFRSF25. PTX-35 is designed to harness the body's natural antigen specific immune activation and tolerance mechanisms to reprogram immunity and provide a long-term, durable clinical effect. TNFRSF25 agonism has been shown to provide highly selective and potent stimulation of antigen experienced ‘memory’ CD8+ cytotoxic T-cells, which are the class of long-lived T-cells capable of eliminating tumor cells in patients. Due to the preferential specificity of PTX-35 to antigen experienced CD8+ T-cells, this agent represents a promising candidate as a T-cell co-stimulator in cancer patients.

When combined in preclinical studies with Heat’s gp96 platform immunotherapies and an anti-PD-1 checkpoint inhibitor, PTX-35 has been shown to enhance antigen specific T-cell activation to eliminate tumor cells. Pelican is also developing other biologics that target TNFRSF25 modulators for various immunotherapy approaches.

Clinical Pipeline

HS-110 (viagenpumatucel-L) – Non-Small Cell Lung Cancer (NSCLC)

Using our licensed ImPACT^® platform technology, we developed the product candidate, HS-110 (viagenpumatucel-L) as a potential treatment for patients with advanced non-small cell lung cancer. HS-110 is our first lead biologic product candidate designed to stimulate a patient’s own T-cells to attack tumor cells. HS-110 is made of a lung adenocarcinoma cancer cell line that has been genetically modified to secrete a wide range of cancer-associated antigens bound to gp96 proteins, thereby activating a broad, T-cell medicated immune response against a patient’s cancer.

We have completed enrollment in our Phase 2 trial of HS-110, in combination with either nivolumab (Opdivo^®), a Bristol-Myers Squibb anti-PD-1 checkpoint inhibitor or more recently, Merck’s anti-PD1 checkpoint inhibitor, pembrolizumab (KEYTRUDA^®), to treat patients with advanced NSCLC. The multicenter clinical trial evaluates the safety and efficacy of HS-110 in combination with nivolumab in a second line or greater setting, or with pembrolizumab in the front-line maintenance setting.

On February 9, 2021, we announced positive interim data from the Phase 2 trial. Substantial survival benefit was observed in a cohort of previously treated, checkpoint inhibitor naïve patients with advanced NSCLC (Cohort A, N = 47). A median progression free survival (PFS) of 1.8 months and a median overall survival (OS) of 24.6 months was observed with a median follow-up time of 19.4 months. The one-year survival rate of Cohort A is 61.7%. The median OS data was 12.2 months and the 1-year survival rate was 50.7% in previously treated, advanced NSCLC patients who received nivolumab as a single agent, according to published data of the BMS CheckMate 057 study.

For NSCLC patients who had previously been treated with a checkpoint inhibitor and whose disease had subsequently progressed (Cohort B, N = 68), a median PFS of 2.8 months and median OS of 11.9 months was observed with a median follow-up time of 11.9 months. Published data from other studies reported median OS of 6.8 to 9.0 months for NSCLC patients treated with chemotherapies after PD-(L)1 progression.

As of this data cut, 30% of the patients in Cohort A and 26% of the patients in Cohort B were still alive. HS-110 has a favorable safety profile and has been administered in approximately 200 patients to date. As of this data cut, there have been no treatment-related serious adverse reactions. A review of immune-related adverse events reported in the study raised no safety concerns. The data to date demonstrate that combination of HS-110 and nivolumab is well-tolerated.

HS-130

We have initiated clinical development of HS-130 for the treatment of advanced solid tumors. This product is designed to test our ComPACT^™ technology approach. HS-130 intradermal delivers a T-cell co-stimulatory fusion protein (OX40L). We have completed preclinical characterization and manufacturing activities for this product candidate.

Our first-in-human study is an open label dose-escalation study evaluating escalating doses of HS-130 in combination with HS-110 in up to 30 patients. The primary endpoints are to evaluate patient safety (treatment emergent adverse events, serious adverse events and dose-limiting toxicities) and to determine the optimal dose for a subsequent Phase 2 trial. We began enrolling patients in this study in 2019 and continue to enroll patients in this study.

Preclinical Pipeline

COVID-19 Vaccine

Our Zolovax subsidiary is focused on developing vaccines for infectious diseases based on our gp96 platform. Our collaborators have laid a good foundation on engineering different pathogenic antigens into our platform. Previous preclinical animal studies conducted includes simian immunodeficiency virus, malaria and Zika. We have initiated development of a COVID-19 vaccine program in collaboration with the University of Miami in March 2020. We utilize our proprietary gp96 platform to engineer multiple protein regions of the virus to activate the human immune system to combat COVID-19. Such design has the potential of generating long-term immune responses and may confer immunity to different coronaviruses.

During the third quarter of 2020 we commenced preclinical testing of the vaccine under a sponsored research agreement. In July 2020, we announced generation of proof- of -concept data demonstrating vaccine immunogenicity in relevant preclinical models, including expansion of human-HLA-restricted T-cells against immunodominant epitopes of SARS-CoV-2 Spike protein. In August 2020, we reported preclinical data for our gp96-based COVID-19 vaccine generated at the University of Miami Miller School of Medicine, showing robust T cell mediated immune response directed against the spike protein of SARS-CoV-2. Also, in August 2020, we announced publication of positive preclinical COVID-19 vaccine results, that included data supporting that our gp96-based COVID-19 vaccine induces systemic and tissue-specific (lung) memory CD8+ T cells and tissue-resident memory CD8+ T cells.

On December 16, 2020 we announced completion of the gp96-based COVID-19 vaccine cell line ("ZVX-60"), which is being developed for use as either a standalone vaccine, or in combination with other vaccines to enhance prophylactic protection. Additional data collected since this announcement using ZVX-60 (gp96/OX40L-Ig, Spike vaccine), includes an in vivo dose-response test in mice showing that ZVX-60 induces HLA-A2 restricted CD8+ T-cells at 0.5 million cells (1000 ng of gp96-Ig). ZVX-60 also upregulates CD69 and CXCR6 markers on CD8+ T-cells in the spleen, lung and BALF, with greatest increase in the BALF. ZVX-60 was able to increase the generation of effector and central memory cells over that of ZVX-55 (i.e., showing the contribution of OX40L addition), and was able to generate anti-Spike IgG and IgM antibodies, greater than ZVX-55.

On January 19, 2021, we announced that we have transferred our gp96-based COVID-19 vaccine cell line ("ZVX-60") to Waisman Biomanufacturing to initiate the manufacturing process for ZVX-60, which is being developed for use as either a standalone vaccine, or in combination with other vaccines, to enhance prophylactic protection against COVID-19.

PTX-35

Pelican Therapeutics is focused on the development of monoclonal antibody and fusion-protein based therapies designed to activate antigen experienced T-cell subsets of the immune system. Pelican’s lead product PTX-35 is a humanized, affinity matured, monoclonal antibody that serves as a functional agonist of human tumor necrosis factor receptor superfamily member 25 (TNFRSF25), also known as death receptor 3 (DR3). This antibody stimulates antigen experienced ‘memory’ CD8+ cytotoxic T-cells with high specificity and potency. These cells are instrumental in destruction of tumor cells. Prior to our acquisition of 80% of Pelican in 2017, Pelican completed (1) humanization and affinity maturation of PTX-35; (2) PTX-35 epitope mapping or mapping of the binding site on the TNFRSF25 that is recognized by PTX-35;

Table of Contents

and (3) stability/development studies of PTX-35. Manufacturing and IND-enabling studies for PTX-35 were successfully completed in preparation for an IND filing for oncology.

Mouse surrogate of PTX-35 (i.e., human CDRs 1-3, but mouse Ig backbone), has shown activity in mouse models of corneal allograft, beta-islet transplantation, bone marrow transplantation, auto/inflammatory models of experimental autoimmune encephalitis (EAE), colitis and asthma. This mouse surrogate version of PTX-35 is a translation tool that allows predictability between in vivo model data and potential human activity.

In June 2020, the U.S. Food & Drug Administration (FDA) cleared the Investigational New Drug (IND) application for PTX-35. In June 2020, we treated the first patient in our first-in-human Phase 1 clinical trial evaluating PTX-35. This first-in-human study is expected to enroll up to 30 patients with advanced solid tumors refractory to standard of care. The Phase 1 clinical trial of PTX-35 is an open-label, single arm, first in human intravenous administration of PTX-35 to patients with advanced solid tumors refractory to, or ineligible for, or who refuse available standard of care. Escalating dose levels of PTX-35 will be explored until optimal immunological dose or maximum tolerated dose is established. The primary objectives of the study include safety evaluation, determination of the recommended Phase 2 dose as well as exploratory analyses of clinical benefit and immunological effect of PTX-35. This trial is supported by a $15.2 million grant from the Cancer Prevention and Research Institute of Texas.

Preclinical studies with the murine precursor of PTX-35 have shown advantages over competing T-cell co-stimulator programs based on the expansion of tumor antigens specific CD8+ T-cells. In preclinical studies in colon, lung and breast cancer models, we have seen favorable results and favorable safety profiles in monkey and mouse studies.

Other TNFRSF25 Modulators

Next generation TNFRSF25 modulators (PTX-45 and others) that are differentiated from PTX-35 are in development. These novel TNFRSF25 immunomodulators may be designed for specific disease indications.

Additional Indications

We continue to evaluate additional indications for the ImPACT^® and ComPACT^™ platform technologies, along with PTX-35 and next generation TNFRSF25 modulator compounds. Specifically, using ComPACT^™, we have developed cell lines for several other cancers with the first product candidate being a second-generation therapy with similar cancer associated antigen overlap in multiple solid tumors (HS-130). Our decision to further pursue any product candidates, or any additional product candidates, will be based in part upon available funding and partnering opportunities.

The success of our ImPACT^® and ComPACT^™ platform therapies will depend on the clinical and regulatory success of our product candidates and our ability to retain, on commercially reasonable terms, financial and managerial resources, which are currently limited. To date, we have not received final regulatory approval for any of our product candidates or derived any revenues from their sales. Moreover, there can be no assurance that we will ever receive regulatory approval for any of our product candidates or derive any revenues from their sales.

Zolovax is in preclinical studies to develop therapeutic and preventative medicines to treat infectious diseases based on our gp96 therapeutic technology, with a current focus on the development of a vaccine to target the SARS-CoV-2 coronavirus that causes COVID-19.

The Oncology Market and Current Treatments

The American Cancer Society estimates that approximately 1.9 million people in the United States will be diagnosed with cancer in 2021. The lifetime probability of being diagnosed with cancer is approximately 40.5% for men and 38.9% for women. It is projected that 608,570 Americans will die from cancer in 2021.

Lung cancer is the second-most commonly diagnosed cancer in the U.S. The American Cancer Society estimates that there will be approximately 235,760 new cases of lung cancer in the United States diagnosed in 2021, accounting for about 12% of all cancer diagnosis. Despite continuous advances made in the field of cancer research every year, there remains a

significant unmet medical need, as the overall five-year relative survival rate for lung cancer patients is 17% for men and 24% for women. Only 17% of lung cancers are diagnosed at a localized stage, for which the five-year survival is 59%. The American Cancer Society estimates that one in four deaths in the United States is due to cancer. Approximately 84% of all lung cancer is NSCLC.

ImPACT^®/ComPACT^™ Platform Technology Advantages

We seek to increase the percentage of patients with long-term benefit to checkpoint inhibitors with a combination treatment that is designed to activate and expand the T-cell’s immune defense mechanisms to seek out and kill cancer cells. ImPACT^®and ComPACT^™, variations of Heat’s gp96-based therapies, have been shown to stimulate an immune response based on a full antigenic repertoire of cancer cell associated proteins, not just one or a handful of antigens. The technologies are designed to combine a broad antigen repertoire of known tumor associated antigens, complexed with a potent immune adjuvant (gp96). The activated immune response generated by our gp96-based therapies may be useful in treating a wide range of cancers and infectious diseases. The advantages include:

●

gp96 therapies are administered with checkpoint inhibitors and other immuno-modulators with the goal of enhancing immune response through T-cell activation. Genetically engineered allogenic cells are injected into the dermal layers of the skin of patients to elicit an immune response against the patient’s own tumor. The treatment primes immune recognition and triggers the body to stimulate a robust adaptive, T-cell mediated immune system to seek and destroy the cancer cells.

●

gp96 therapies are allogeneic, off-the-shelf treatments designed to activate the immune system to turn immunologically "cold" tumors "hot." With ImPACT^®, therapies can be administered alongside checkpoint inhibitors and other immuno-modulators to increase effectiveness. Our ComPACT^™ therapy combines antigen delivery and cross presentation with a highly selective T-cell co-stimulator within a single treatment, simplifying combination immunotherapy, while providing superior immune activation/expansion with reduced treatment costs.

●

Our “off-the-shelf,” cancer-fighting therapies are designed to expand cancer reactive immune cells to recognize and kill cancer cells. They jump-start immune recognition of common, cancer associated neo-antigens (proteins expressed normally in development prior to the upregulation of MHC expression) that are re-expressed in the cancer upon malignant transformation. When used alongside checkpoint inhibitors, they have been shown to boost T-cell activity to more effectively target and destroy cancer cells.

●

We don’t require invasive procedures or the isolation of patient tissues. We are not extracting anything from anyone. This eliminates the inconvenience and costs associated with securing, expanding, storing and transporting patient samples, while eliminating potential surgical risks.

●

Our therapies do not require an additional adjuvant, or immune stimulant. Other immunotherapies may require the addition of an adjuvant to enhance effectiveness and reduce toxicity. Our product candidate incorporates gp96, itself a powerful biological adjuvant, ensuring that no additional immune adjuvants are necessary to generate an activated, T-cell mediated immune response.

●

Custom manufacturing is not necessary. Our products are mass-produced and readily available for immediate patient use. Each patient receives the same treatment, offering logistical, manufacturing and other cost benefits, compared to patient-specific or “personalized” medicine approaches.

PTX-35 and Next Generation TNFRSF25 Modulator Advantages

The advantages include:

●

Pelican provides access to a T-cell co-stimulator and novel TNFRSF25 modulators in development that further broadens our pipeline and strengthens our portfolio within the emerging T-cell co-stimulation space. We believe the use of these therapeutic agents, in combination with other immunotherapies, have the potential to be synergistic with our TCAP to dramatically improve patient outcomes.

●

Pelican is the only company with a disclosed preclinical pipeline targeting the T-cell co-stimulator, TNFRSF25. We believe PTX-35 can activate antigen-specific memory CD8+ cytotoxic T-cells that has the potential to eliminate patient’s tumor cells. This approach is designed to harness the body’s natural antigen specific immune activation and tolerance mechanisms to reprogram and expand antigen experienced immunity, to support a long-term, durable therapeutic effect. When combined with immunotherapies, including the ImPACT^® and ComPACT^™ platform technologies, PTX-35 enhances antigen specific T-cell activation to eliminate tumor cells.

●

Preclinical studies with the murine precursor to PTX-35 show advantages over competing T-cell co-stimulator programs based on CD8+ T-cell specificity.

●

Next generation TNFRSF25 modulators may improve on PTX-35 and have unique properties such as improved affinity or avidity or a shorter half-life.

COVID-19 Vaccine Advantages

This is a potential first-in-class COVID-19 vaccine designed to generate long-term immune responses and may confer immunity to different coronaviruses. Our COVID-19 vaccine program is incorporating multiple SARS-CoV-2 antigens using our gp96 platform. We are mimicking the natural immune process to induce long-term immunity and to confer protection for individuals against future infections. In contrast to other vaccine approaches, our platform offers the following advantages:

●

No anti-vector immunity given that we are not using a virus-based vector-system

●

No viral activation as we do not utilize any attenuated virus

●

Both T cells and B cells are activated with high immunogenicity to drive induction of mucosal immunity and long-term memory response

Strategy

Our objective is to become a leading biopharmaceutical company specializing in the development and commercialization of allogeneic, “off-the-shelf” immunotherapies. ImPACT^® and ComPACT^™ are designed to address synergistic mechanisms of action: natural delivery of a robust repertoire of cancer associated antigens (CTAs) coupled with the activation, co-stimulation and expansion of cancer-specific killer T-cells to further enhance patients’ immune activity and immune memory. Pelican’s lead compound, PTX-35, is a humanized affinity matured TNFRSF25 agonist antibody, and potential best-in-class T-cell co-stimulator due to its preferential antigen specific memory CD8+ T-cells that are considered most potent in eliminating cancer cells. Preclinical studies with systemically administered PTX-35 show advantages over competing T-cell co-stimulator programs. In addition, Pelican is the only company with a disclosed program targeting TNFRSF25 for use in immuno-oncology, with a broad, pioneering intellectual property estate. Our gp96-based COVID-19 vaccine program is being developed for use as either a standalone vaccine, or in combination with other vaccines, to enhance prophylactic protection against COVID-19.

We believe future cancer immunotherapies will involve multiple agents and our platforms could work synergistically with therapies, such as checkpoint inhibitors, which are designed to reverse tumor-induced immune exhaustion and suppression. We are focused on discovering, developing, and applying the ImPACT^® and ComPACT^™ platform technologies, and our PTX-35 compound in combination with other immunotherapies towards a number of disease indications. The key elements of our strategy are:

●

Develop and obtain regulatory approval for our product candidates. We have completed enrollment of the HS 110 trial in combination with either nivolumab or pembrolizumab to treat patients with advanced NSCLC. We have initiated enrollment in our Phase 1 trial of HS-130 in combination with H-110 for treatment of solid tumors and our Phase 1 trial of PTX-35 for the treatment of solid tumors. Beyond these trials – depending upon funding and partnering opportunities – we plan to initiate new clinical trials of combined immunotherapy agents.

●

Maximize commercial opportunity for the ImPACT® and ComPACT™ technology, as well as our PTX 35 and next generation TNFRSF25 modulator compounds. Our current product candidates target large markets with significant unmet medical needs. For each of our product candidates, we seek to maximize the economic potential of any future U.S. or international commercialization efforts.

●

Enhance our partnering efforts. We are continually exploring partnerships for licensing and other collaborative relationships and remain opportunistic in seeking strategic partnerships that maximize our economic potential.

●

Further expand our broad patent portfolio. We have made a significant investment in the development of our patent portfolio to protect our technologies and programs, and we intend to continue to do so. We have obtained exclusive rights to six different patent families directed to therapeutic compositions and methods related to our platform and preclinical development programs for cancer, and have filed additional patent applications that are owned by us. The ImPACT^®/ComPACT^™ patent portfolio comprise more than 30 granted patents and 40 pending patent applications. These patents and applications cover the United States, Europe, and Japan, as well as several other countries having commercially significant markets. In total, Pelican holds approximately 50 granted U.S. and foreign patents and approximately 20 U.S. and foreign patents are pending.

●

Manage our business with efficiency and discipline. We believe we have efficiently utilized our capital and human resources to develop and acquire our product candidates and programs and create a broad intellectual property portfolio. We operate cross-functionally and are led by an experienced management team with backgrounds in developing and commercializing product candidates. We use project management techniques to assist us in making disciplined strategic program decisions and to attempt to limit the risk profile of our product pipeline.

●

Obtain additional non-dilutive grant funding in addition to Pelican’s $15.2 million CPRIT Grant. To develop our technologies and compounds more fully, and their application to a variety of human diseases, we plan to continue to seek and access external sources of grant funding on our own behalf and in conjunction with our academic and other partners, including retention of lobbyists, to support the development of our pipeline programs. While we intend to work with our academic partners to secure additional grant funding, these partners have no obligation to work with us to secure such funding. We also intend to continue to evaluate opportunities and, as appropriate, acquire or license technologies that meet our business objectives.

Pelican Acquisition

On April 28, 2017, we consummated the acquisition of 80% of the outstanding equity of Pelican, a related party, and Pelican became our majority owned subsidiary as contemplated by the Stock Purchase Agreement (the “Purchase Agreement”) that we entered into with Pelican, and certain stockholders of Pelican holding a majority of the outstanding shares.

Table of Contents

Pelican is a biotechnology company focused on the development and commercialization of monoclonal antibody and fusion protein-based therapies that are designed to activate the immune system. In exchange for 80% of the outstanding capital stock of Pelican on a fully diluted basis, we paid to the Pelican Stockholders that executed the Stock Purchase Agreement (the “Participating Pelican Stockholders”) an aggregate of $0.5 million minus certain liabilities (the “Cash Consideration”), and issued to the Participating Pelican Stockholders 19,015 shares of our restricted common stock representing 4.99% of the outstanding shares of our common stock on the date of the initial execution of the Purchase Agreement (the “Stock Consideration”). The Pelican Stockholders that sold their shares in Pelican to us (the “Participating Pelican Stockholders”) included Jeffrey Wolf, our Chief Executive Officer and a director, John Monahan and Edward Smith, two of our directors, the Chairman of our Scientific Advisory Committee at the time of the closing and/or entities controlled by them. During the year ended December 31, 2018, the Cash Consideration of approximately $0.3 million was distributed to the Participating Pelican Stockholders and the remainder of approximately $0.2 million for certain Pelican liabilities not satisfied was retained by us and recognized as other income in the Consolidated Statements of Operations and Comprehensive Loss. During the year ended December 31, 2020, we distributed to the Participating Pelican Stockholders $2.0 million upon dosing of the first patient in our Phase 1 trial of PTX-35, of which approximately of 22% was distributed to our executive officers and directors who are Participating Pelican Stockholders.

Under the Purchase Agreement, we are also obligated to make future payments based on the achievement of certain clinical and commercialization milestones, as well as low single digit royalty payments and payments upon receipt of sublicensing income:

(1)

$1.5 million upon Pelican’s dosing of the first patient in its first Phase 2 trial for an oncology indication;

(2)

$3.0 million upon successful outcome of the first Phase 2 trial for an oncology indication;

(3)

$6.0 million upon Pelican’s dosing of the first patient in its first Phase 3 trial for an oncology indication;

(4)

$3.0 million upon Pelican’s dosing of the first patient in its first Phase 3 trial for a non-oncology indication;

(5)

$7.5 million upon successful outcome of the first Phase 3 trial for an oncology indication;

(6)

$3.0 million upon successful outcome of the first Phase 3 trial for a non-oncology indication;

(7)

$7.5 million upon acceptance of a Biologics License Application (BLA) submission for an oncology indication;

(8)

$3.0 million upon acceptance of a BLA submission for a non-oncology indication;

(9)

$7.5 million upon first product indication approval in the United States or Europe for an oncology indication; and

(10)

$3.0 million upon first product indication approval in the United States or Europe for a non- oncology indication.

Pelican has been awarded $15.2 million to fund preclinical and some clinical activities from Cancer Prevention Institute of Texas (CPRIT) grant (the “CPRIT Grant”). The CPRIT Grant is subject to customary CPRIT funding conditions including a matching funds requirement where Pelican will match $0.50 for every $1.00 from CPRIT, which totals $7.6 million over the life of the project.

In connection with the Pelican Acquisition, the Participating Pelican Stockholders entered into a Stockholders’ Agreement (the “Stockholders’ Agreement”) with us with respect to the Pelican common stock retained by the Participating Pelican Stockholders (the “Retained Shares”). The Stockholders’ Agreement, contains restrictions on transfer of the Retained Shares and drag-along rights in the event of a consolidation or merger of Pelican with another entity after the date of the Purchase Agreement or the sale of all or substantially all of Pelican’s assets or a transaction in which at least fifty percent (50%) of the voting rights attached to the Pelican securities are sold. In addition, Participating Pelican Stockholders will have co-sale rights in connection with our transfer of the Pelican common stock that we own.

In October 2018, we entered into an agreement with the University of Miami (“UM”) whereby UM exchanged its shares of Pelican stock, of which it owned 5% equity on a fully diluted basis for a certain number of shares along with UM shares in Heat Biologics I, Inc., of which it owned 7.5% equity (together herein the “Subsidiary Shares”) for 5,000 shares of Heat Biologics, Inc. common stock, $0.0002 par value; resulting in Heat owning 85% of Pelican and 100% of its subsidiary Heat Biologics I.

CPRIT Grant

In May 2016, Pelican was awarded a $15.2 million CPRIT Grant from CPRIT for development of Pelican’s lead product candidate, PTX-35. The CPRIT Grant is expected to allow Pelican to develop PTX-35 through a 40-50 patient Phase 1

Table of Contents

clinical program. The CPRIT Grant is subject to customary CPRIT funding conditions including a matching funds requirement where Pelican will match $0.50 for every $1.00 from CPRIT. Consequently, Pelican is required to raise $7.6 million in matching funds over the life of the project.

As of December 31, 2020, CPRIT has provided $13.7 million of the total $15.2 million grant. The remaining $1.5 million will be awarded, on a reimbursement basis, after we have fulfilled every requirement of the grant and the grant has been approved to be finalized, rather than in advance of expending the funds as in the prior grant years. As of December 31, 2020, we have provided approximately $6.6 million which was used to satisfy Pelican’s matching fund obligation under the first four years of the CPRIT Grant. Approximately $1.0 million is remaining to provide in the fifth year of the CPRIT grant.

The CPRIT Grant, as is customary for all CPRIT awards, contains a requirement that Pelican pay CPRIT a royalty on sales of commercial products developed using CPRIT funds equal to between three and five percent of revenue until such time as CPRIT has been paid an aggregate amount equal to 400% of the grant award proceeds. After 400% of the grant award proceeds has been paid, Pelican will pay CPRIT a royalty of 0.5% in perpetuity. After the CPRIT Grant terminates, Pelican is not permitted to retain any unused grant award proceeds without CPRIT’s approval, but Pelican’s royalty and other obligations, including its obligation to repay the disbursed grant proceeds under certain circumstances, to maintain certain records and documentation, to notify CPRIT of certain unexpected adverse events and Pelican’s obligation to use reasonable efforts to ensure that any new or expanded preclinical testing, clinical trials, commercialization or manufacturing related to any aspect of our CPRIT project take place in Texas, survive the termination of the agreement. In addition, if Pelican relocates its principal place of business outside of Texas within the three year period after the date of final payment of grant funds (which final payment has not yet occurred), we are required to repay to CPRIT all grant funds received. Pelican expects to have received and expended all of the grant award proceeds by the agreement termination date.

The CPRIT Grant is subject to Pelican complying with all terms set forth in the CPRIT Grant, including Pelican maintaining its status with CPRIT as a Texas-based entity. In order to qualify as a Texas-based entity, a company must fulfill a majority of the following seven requirements: (i) its US headquarters must be physically located in Texas; (ii) its chief executive officer must reside in Texas; (iii) a majority of its personnel, including at least two other senior-level employees, must reside in Texas; (iv) its manufacturing activities must take place in Texas; (v) at least 90% of its grant award funds must be paid to individuals and entities in Texas, including salaries and personnel costs for employees and contractors: (vi) at least one clinical trial site must be in Texas; and (vii) it must collaborate with a medical research organization in Texas, including a public or private institution of higher education. Currently, Pelican meets a majority of these seven requirements.

Intellectual Property

Our goal is to obtain, maintain and enforce patent protection for our products, formulations, processes, methods and other proprietary technologies; preserve our trade secrets and exclusive rights in our unique biological materials; and operate without infringing on the proprietary rights of other parties, both in the United States and in other countries. Our policy is to actively seek to obtain, where appropriate, the strongest intellectual property protection possible for our current product candidates and any future product candidates and our subsidiaries’, proprietary information and proprietary technology through a combination of contractual arrangements and patents, both in the United States and abroad. However, even patent protection may not always afford us with complete protection against competitors who seek to circumvent our patents. See “Risk Factors – Risks Relating to Our Business – We have limited protection for our intellectual property, which could impact our competitive position.”

We will continue to depend upon the skills, knowledge and experience of our scientific and technical personnel, as well as that of our advisors, consultants and other contractors, none of which is patentable. To help protect our proprietary know-how, which is not patentable, and for inventions for which patents may be difficult to enforce, we currently rely and will in the future rely on trade secret protection and confidentiality agreements to protect our interests. To this end, we require all of our employees, consultants, advisors and other contractors to enter into confidentiality agreements that prohibit the disclosure of confidential information and, where applicable, require disclosure and assignment to us of the ideas, developments, discoveries and inventions important to our business.

exclusive license agreement that was also entered into with UM in February 2011. No upfront, annual or milestone payments are required to be paid to the University under either of these license agreements. The license agreements grant Heat Biologics I, Inc. exclusive, worldwide rights to make, use or sell licensed materials based upon the patent-related rights.

As consideration for the rights granted in each of these three license agreements, Heat Biologics I, Inc. is obligated to pay royalties equal to a percentage (in the low-to-mid single digits) of net sales of products covered by the patent-related rights in the respective license agreements. These royalty rates are subject to reduction if additional license rights from third parties are required to commercialize licensed products. In the event of a sublicense to a third party, Heat Biologics I, Inc. is obligated to pay royalties to UM equal to a percentage of sublicense income. Each of these additional license agreements also provides that the licensee will not have to pay more than the above-noted royalty rates and sublicense fees if more than one license from UM is required to sell products covered by the licensed patent-related rights.

All of the above-described license agreements, as amended, provide that the licensor has the right to terminate a subject license if the licensee: (1) has not introduced, or at least used its best efforts to introduce, a licensed product in the commercial marketplace in the United States, European Union, or Japan by December 31, 2025; (2) has not otherwise exercised diligence to bring licensed products to market; or (3) files, or has filed against it, a proceeding under the Bankruptcy Act, is adjudged insolvent, makes an assignment for the benefit of its creditors, or has an unreleased or unsatisfied writ of attachment or execution levied upon it. Upon an uncured material breach of an obligation under any one of the above license agreements by a party, the other party has the right to terminate that agreement upon 90 days’ notice or 30 days’ notice if the breach relates to payments due to UM. In the event of a termination, Heat Biologics I, Inc. will be obligated to pay all amounts that accrued prior to such termination. Each of the above license agreements also contains other customary clauses and terms as are common in similar agreements between industry and academia, including the licensee’s agreement to indemnify UM for liabilities arising out of the negligence of the licensee, making the license grant subject to the Bayh-Dole act (35 U.S.C. 200 et seq.), the reservation of the licensor of the right to use the licensed intellectual property rights for its internal, non-commercial purposes, limitations/disclaimers of various warranties and representations, reporting and record-keeping requirements, and licensee liability insurance requirements.

In June 2016, we entered into an exclusive license agreement with Shattuck Labs, Inc. (“Shattuck”) pursuant to which we licensed to Shattuck certain provisional patent applications and know-how related to fusion proteins to treat cancer and other diseases that were not being developed by us. Shattuck paid us an initial license fee of $50,000 and is obligated to pay us fees upon its receipt of sublicensing income, achievement of certain milestones and royalties upon sales of commercial products. Inasmuch as the technology that we out-licensed is in the early stages of development and there is a low likelihood of success for any technology at such stage, there can be no assurance that any products will be developed by Shattuck or that we will derive any revenue from Shattuck.

Zolovax Licenses

In October 2016, our wholly-owned subsidiary, Zolovax, Inc., entered into an agreement with UM for the license and development of a portfolio of patents leveraging its gp96 platform to target the Zika virus and other infectious diseases. The preclinical studies using the licensed technology have been initiated and are progressing. The term of the license is the length of the last to expire patent, unless terminated earlier. The license agreement grants Zolovax, Inc. exclusive, worldwide rights to make, use or sell licensed materials based upon the patent-related rights. As consideration for the rights granted in this license agreement, the licensee paid an upfront fee, is obligated to pay annual payments commencing on the third anniversary of the license agreement and royalties equal to a percentage (in the low-to-mid single digits) of net sales of products covered by the patent-related rights in the respective license agreements. These royalty rates are subject to reduction if additional license rights from third parties are required to commercialize licensed products. In the event of a sublicense to a third party, Zolovax, Inc. is obligated to pay royalties to UM equal to a percentage of sublicense income. The license agreement provides for diligence milestones payments of up to an aggregate of $1,450,000 that include pre-IND meeting with the FDA, IND submission to the FDA and dosing first patient in a Phase 1 clinical trial. The license agreement also provides that the licensee will not have to pay more than the above-noted royalty rates if more than one license from UM is required to sell products covered by the licensed patent-related rights. The license agreement provides that the licensor has the right to terminate a subject license if the licensee has engaged in certain bankruptcy events or has breached the terms of the license agreement which includes having (i) failed to make a required payment; (ii) failed to

Table of Contents

achieve a milestone or not otherwise exercised diligence to bring licensed products to market; (iii) failed to possess insurance coverage, or (iv) filed a false report. Upon an uncured material breach of an obligation that remains uncured for 30 days’ after notice thereof, the other party has the right to terminate that agreement. In March 2020, we entered into a research agreement with UM pursuant to which we sponsor the research and development of COVID-19 vaccine using our gp96 platform and a research agreement with UM for the development of a COVID-19 point-of-care diagnostic test. In May 2020, we suspended the point-of-care diagnostic program due to the progress made by other diagnostic manufacturers utilizing a similar approach, and our desire to focus resources on the COVID-19 vaccine program. In the process, we developed our own unique diagnostic intellectual property, and plan to opportunistically explore partnership opportunities around this technology.

On December 31, 2020, Zolovax entered into an exclusive license agreement with UM for the license and development of a portfolio of patents leveraging its UMIP-510 platform to target the COVID-19 virus and other infectious diseases. The license agreement grants Zolovax exclusive, worldwide rights to research, develop, make, use or sell Licensed Products (as defined in the license agreement) based upon patent-related rights. The term of the license is the later of the length of the last to expire patent or fifteen (15) years from the date of the first sale of a Licensed Product unless terminated earlier. As consideration for the rights granted in the license agreement, Zolovax paid an upfront fee of $2,500, is obligated to pay certain annual payments and to pay royalties equal to a percentage (in the low-to-mid single digits) of net sales of Licensed Products. These royalty rates are subject to reduction if additional license rights from third parties are required to commercialize the Licensed Products. In the event of a sublicense to a third party, Zolovax is obligated to pay royalties to UM equal to a percentage of sublicense income. The license agreement provides for diligence milestones that include IND submission to the FDA or EMA within twenty-four months of the effective date of the license agreement, dosing first patient in a Phase 1 clinical trial within nine months of approval of an IND, and making commercially reasonable efforts towards obtaining regulatory marketing approval for a Licensed Product form either the FDA or EMA. The license agreement also provides for commercial milestone payments of up to an aggregate of $7,750,000 upon the achievement of $10,000,000, $100,000,000 and $500,000,000 of cumulative net sales of License Products. The License Agreement provides that Zolovax may terminate the license agreement upon ninety days’ notice to UM, UM has the right to terminate the license agreement if Zolovax has engaged in certain bankruptcy events and each party has the right to terminate the license agreement if the other party commits a material breach of the terms of the license agreement, and such breach remains uncured for thirty days.

Under license agreements with UM, Pelican has obtained exclusive rights to six different patent families each directed to therapeutic compositions and methods related to targeting TNFRSF25/TL1A for the purpose of modulating immune responses. These families comprise approximately 45 granted U.S. and foreign patents, and approximately 30 U.S. and foreign patent applications. These patents and applications cover the United States, Europe and Japan as well as several other countries having commercially significant markets. As partial consideration for the initial two license agreements with UM, Pelican issued UM 300,000 shares of its common stock of which UM transferred to Heat in exchange for shares of our common stock in October 2018.

As consideration for the rights granted under the initial license agreement, UM-143 and UMN-106 non-oncology, Pelican is obligated to pay UM certain upfront license fees and milestone payments of ((i) $25,000 upon submission of an IND, (ii) $25,000 upon approval of an IND, (iii) $100,000 upon completion of a Phase 1 clinical trial and (iv) $250,000 the earlier of May 2022 or approval of a NDA), an annual minimum royalty payment $20,000 and royalties (mid-range single digits) based on net sales on commercialized products covered by the patent-related rights set forth above.

As consideration for the rights granted under the second license agreement, UMI-176, Pelican is obligated to pay UM certain upfront license fees, and aggregate milestone payments of (i) $25,000 upon submission of an NDA, (ii) $25,000 upon approval of a NDA; (iii) $100,000 upon completion of Phase 1 clinical trial and (iv) $500,000 the earlier of May 2022 or approval of an NDA), an annual minimum royalty payment $20,000 and royalties (mid-range single digits) based on net sales on commercialized products covered by the patent-related rights set forth above.

As consideration for the rights granted in the third license agreement, UM03-31 and UM05-39, Pelican is obligated to pay UM certain upfront license fees, past and future patent costs, an annual minimum royalty payment $20,000 and royalties

(mid-range single digits) based on net sales on commercialized products covered by the patent-related rights set forth above. The third license agreement with UM provides that in the event that Pelican terminates its second license agreement with UM, Pelican is obligated to pay UM an annual minimum royalty payment of $20,000 for each year after 2014 during the term of the third license agreement as well as the following milestone payments: (i) $25,000 upon submission of an IND; (ii) $25,000 upon approval of a NDA; (iii) $100,000 upon completion of a Phase 1 clinical trial; and (iv) $250,000 the earlier of May 31, 2022 or approval of a NDA. The royalty rates are subject to reduction if additional license rights from third parties are required to commercialize licensed products. In the event of a sublicense to a third party, Pelican is obligated to pay royalties to UM equal to a percentage of sublicense income. The third license agreement also provides that Pelican will not have to pay more than above royalty rates and sublicense fees if more than one license from UM is required to sell products covered by the licensed patent-related rights.

All of the above-described Pelican license agreements provide that the licensor has the right to terminate a subject license if the licensee (1) has not introduced, or at least used its best efforts to introduce, a licensed product in the commercial marketplace in the United States, European Union, or Japan by December 31, 2022 (December 2025 for the UMI-176 license agreement); (2) has not otherwise exercised diligence to bring licensed products to market; or (3) files, or has filed against it, a proceeding under the Bankruptcy Act, is adjudged insolvent, makes an assignment for the benefit of its creditors, or has an unreleased or unsatisfied writ of attachment or execution levied upon it. Upon an uncured material breach of an obligation under any one of the above license agreements by a party, the other party has the right to terminate that agreement upon 90 days’ notice or 30 days’ notice if the breach relates to payments due to UM. In the event of a termination, Pelican will be obligated to pay all amounts that accrued prior to such termination. Each of the above license agreements also contains other customary clauses and terms as are common in similar agreements between industry and academia, including the licensee’s agreement to indemnify UM for liabilities arising out of the negligence of the licensee, making the license grant subject to the Bayh-Dole act (35 U.S.C. 200 et seq.), the reservation of the licensor of the right to use the licensed intellectual property rights for its internal, non-commercial purposes, limitations/disclaimers of various warranties and representations, reporting and record-keeping requirements, and licensee liability insurance requirements.

Manufacturing

We rely on third-party manufacturers to produce and store our product candidates for clinical use and currently do not own or operate manufacturing facilities.

We utilized an external vendor for manufacturing of HS-110 used in our Phase 2 clinical trial. We have an agreement with GenCure Biomanufacturing for optimization of the HS-110 manufacturing process and for the manufacture of GMP material to support initiation of a Phase 3 program.

The HS-110 product used in the inventor’s Phase 1, and in our Phase 2 clinical trial was manufactured under cGMP (current good manufacturing practices). The gp96 cell line is grown in large quantities, dispensed into individual doses, frozen in liquid nitrogen, irradiated to render cell replication incompetent and quality tested in compliance with FDA guidelines. The product is irradiated, which is a commonly used attenuation process that eliminates the ability of the gp96-Ig-containing cell lines to replicate but allows them to remain metabolically active and secrete gp96-Ig. The batches of frozen, irradiated drug product are stable for long periods of time and are thawed immediately prior to administration to patients

Heat has also begun development of an additional product, HS-130, for treatment of select solid tumors. This product will utilize our ComPACT^™ technology concept, which is designed to deliver the gp96 heat shock (HS-110) protein and a T-cell co-stimulatory fusion protein (OX40L) in HS-130. We have completed the cGMP manufacturing and nonclinical IND enabling activities to support the clinical development of this product. This product is currently being used in a Phase 1 clinical trial.

Heat has also begun manufacturing of its gp96-based COVID-19 vaccine cell line ("ZVX-60"), using Waisman Biomanufacturing, which is being developed for use as either a standalone vaccine, or in combination with other vaccines, to enhance prophylactic protection against COVID-19.

Pelican is focused on the development of monoclonal antibody and fusion-protein based therapies designed to activate specific T-cell subsets of the immune system. We have utilized an external vendor for development of PTX-35, a humanized affinity matured monoclonal antibody that is a functional agonist of human TNFRSF25. This antibody provides highly selective and potent stimulation of ‘memory’ CD8+ cytotoxic T-cells. This is a subset of the class of T-cell that is responsible for eliminating tumor cells in patients.

We have performed assay development work at our Texas laboratory to support our clinical needs as well as those of third parties. In an effort to decrease our dependence upon third party manufacturers and enhance efficiency, we are exploring the establishment of process development and manufacturing capability to support our clinical trials and potentially third party manufacturing needs.

Competition

The pharmaceutical, biologics and the diagnostic industry is highly competitive and characterized by a number of established large companies, and mid-sized companies, as well as smaller companies like ours. If our competitors’ market products that are less expensive, safer or more effective than any future products developed from our product candidates, or that reach the market before our approved product candidates, we may not achieve commercial success. Technological developments in our field of research and development occur at a rapid rate and we expect competition to intensify as advances in this field are made. We will be required to continue to devote substantial resources and efforts to our research and development activities. As a biotechnology company with cancer immunotherapy agents as lead product candidates, we compete with a broad range of companies. At the highest level, cancer immunotherapy can be seen as both a complement and a potential competitor to any oncology therapy, most notably chemotherapy, radiotherapy, biologics and small molecule drugs. Not only do we compete with companies engaged in various cancer treatments including radiotherapy and chemotherapy, but we also compete with various companies that have developed or are trying to develop immunology vaccines for the treatment of cancer. Certain of our competitors have substantially greater capital resources, large customer bases, broader product lines, sales forces, greater marketing and management resources, larger research and development staffs with extensive facilities and equipment than we do and have more established reputations as well as global distribution channels. Our most significant competitors, among others, are fully integrated pharmaceutical companies such as Eli Lilly and Company, Bristol-Myers Squibb Company, Merck & Co., Inc., Novartis AG, MedImmune, LLC (a wholly owned subsidiary of AstraZeneca plc), Johnson & Johnson, Pfizer Inc., MerckKGaA and Sanofi SA, and more established biotechnology companies such as Genentech, Inc. (a member of the Roche Group), Amgen Inc., Gilead Sciences, Inc. and its subsidiary Kite Pharma, Inc., and competing cancer immunotherapy companies such as, Bluebird Bio, Inc., Transgene SA, Bausch Health Companies, NewLink Genetics Corporation, Agenus Inc., Aduro Biotech, Inc., Advaxis, Inc., ImmunoCellular Therapeutics, Ltd., IMV Inc., Oxford BioMedica plc, Bavarian Nordic A/S, Celldex Therapeutics, Inc., and others, some of which have substantially greater financial, technical, sales, marketing, and human resources than we do. These companies might succeed in obtaining regulatory approval for competitive products more rapidly than we can for our products. In addition, competitors might develop technologies and products that are less expensive, safer or more effective than those being developed by us or that would render our technology obsolete. In addition, the pharmaceutical and biotechnology industry is characterized by rapid technological change. Because our research approach integrates many technologies, it may be difficult for us to remain current with the rapid changes in each technology. If we fail to stay at the forefront of technological change, we may be unable to compete effectively. Our competitors may render our technologies obsolete by advancing their existing technological approaches or developing new or different approaches.

We expect to compete with other pharmaceutical and biotechnology companies, and our competitors may:

●

develop and market products that are less expensive, more effective or safer than our future products;

●

commercialize competing products before we can launch any products developed from our product candidates;

●

operate larger research and development programs, possess greater manufacturing capabilities or have substantially greater financial resources than we do;

●

initiate or withstand substantial price competition more successfully than we can;

Table of Contents

●

have greater success in recruiting skilled technical and scientific workers from the limited pool of available talent;

●

more effectively negotiate third-party licenses and strategic relationships; and

●

take advantage of acquisition or other opportunities more readily than we can.

We expect to compete for market share against large pharmaceutical and biotechnology companies, smaller companies that are collaborating with larger pharmaceutical companies, new companies, academic institutions, government agencies and other public and private research organizations.

The primary treatments for non-small cell lung cancer are surgery, radiation, chemotherapy, checkpoint inhibitors, targeted therapies and various combinations of each of these treatments. A large number of patients, particularly with advanced disease, are refractory to these treatments and are subsequently treated with a number of emerging biologic agents, including immunotherapy. Some examples of therapies commonly attempted with stage IIIB/IV NSCLC patients include: Opdivo^® (nivolumab), Keytruda^® (pembrolizumab), Alimta^® (pemetrexed), Avastin^® (bevacizumab), Tarceva^® (erlotinib), Gemzar^® (gemcitabine), Paraplatin^®(carboplatin), Taxol^® (paclitaxel), Taxotere^® (docetaxel), and Navelbine^®(vinorelbine). It is unlikely that biologic agents will compete with more traditional therapies in the short-term, but many oncologists believe that such therapies will eventually become the mainstay of lung cancer therapy. None of these agents have proven particularly effective for stage IIIB/IV NSCLC patients, with the most effective therapies only increasing survival by a few months. As a result, we do not consider these agents to be direct competitors to HS-110 because they are likely to be given either in sequence or in conjunction with some of the agents listed. Furthermore, many patients cannot tolerate many of the chemotherapeutics listed. Thus, we believe if HS-110 has a positive safety profile (without observation of local or systemic toxicities, none of which have been seen to date), it is possible that HS-110 would be preferred both by physicians and patients in this stage of disease.

Our strategy is to emphasize what we believe to be our competitive advantages, which our products in development are expected to have less side effects than most other cancer therapies, be available at lower prices than other therapies, and ultimately could work on many types of cancer and not just one specific type.

Government Regulation

FDA Approval Process

In the United States, pharmaceutical products are subject to extensive regulation by the FDA. The Federal Food, Drug, and Cosmetic Act, (the “FDC Act”), and other federal and state statutes and regulations, govern, among other things, the research, development, testing, manufacture, storage, recordkeeping, approval, labeling, promotion and marketing, distribution, post-approval monitoring and reporting, sampling, and import and export of pharmaceutical products. Biological products used for the prevention, treatment, or cure of a disease or condition of a human being are subject to regulation under the FDC Act, except the section of the FDC Act which governs the approval of new drug applications, or NDAs. Biological products are approved for marketing under provisions of the Public Health Service Act, or PHSA, via a Biologics License Application, or BLA. However, the application process and requirements for approval of BLAs are very similar to those for NDAs, and biologics are associated with similar approval risks and costs as drugs. Failure to comply with applicable U.S. requirements may subject a company to a variety of administrative or judicial sanctions, such as FDA refusal to approve pending NDAs or BLAs, warning or untitled letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, civil penalties, and criminal prosecution.

Pharmaceutical product development for a new product or certain changes to an approved product in the United States typically involves preclinical laboratory and animal tests, the submission to the FDA of an investigational new drug application, or IND, which must become effective before clinical testing may commence, and adequate and well-controlled clinical trials to establish the safety and effectiveness of the drug for each indication for which FDA approval is sought. Satisfaction of FDA pre-market approval requirements typically takes many years and the actual time required may vary substantially based upon the type, complexity, and novelty of the product or disease.

Table of Contents

Preclinical tests include laboratory evaluation of product chemistry, formulation, and toxicity, as well as animal trials to assess the characteristics and potential safety and efficacy of the product. The conduct of the preclinical tests must comply with federal regulations and requirements, including good laboratory practices. The results of preclinical testing are submitted to the FDA as part of an IND along with other information, including information about product chemistry, manufacturing and controls, and a proposed clinical trial protocol. Long term preclinical tests, such as animal tests of reproductive toxicity and carcinogenicity, may continue after the IND is submitted.

A 30-day waiting period after the submission of each IND is required prior to the commencement of clinical testing in humans. If the FDA has neither commented on nor questioned the IND within this 30-day period, the clinical trial proposed in the IND may begin.

Clinical trials involve the administration of the investigational new drug or biologic to healthy volunteers or patients under the supervision of a qualified investigator. Clinical trials must be conducted: (1) in compliance with federal regulations; (2) in compliance with good clinical practice, or GCP, an international standard meant to protect the rights and health of patients and to define the roles of clinical trial sponsors, administrators, and monitors; as well as (3) under protocols detailing the objectives of the trial, the parameters to be used in monitoring safety, and the effectiveness criteria to be evaluated. Each protocol involving testing on U.S. patients and subsequent protocol amendments must be submitted to the FDA as part of the IND.

The FDA may order the temporary or permanent discontinuation of a clinical trial at any time, or impose other sanctions, if it believes that the clinical trial either is not being conducted in accordance with FDA requirements or presents an unacceptable risk to the clinical trial patients. The study protocol and informed consent information for patients in clinical trials must also be submitted to an institutional review board, or IRB, for approval. An IRB may also require the clinical trial at the site to be halted, either temporarily or permanently, for failure to comply with the IRB’s requirements, or may impose other conditions.

Clinical trials to support NDAs or BLAs for marketing approval are typically conducted in three sequential phases, but the phases may overlap. In Phase 1, the initial introduction of the drug or biologic into healthy human subjects or patients, the product is tested to assess metabolism, pharmacokinetics, pharmacological actions, side effects associated with increasing doses, and, if possible, early evidence on effectiveness. Phase 2 usually involves trials in a limited patient population to evaluate the effectiveness of the drug or biologic for a particular indication, dosage tolerance, and optimum dosage, and to identify common adverse effects and safety risks. If a compound demonstrates evidence of effectiveness and an acceptable safety profile in Phase 2 evaluations, Phase 3 trials are undertaken to obtain the additional information about clinical efficacy and safety in a larger number of patients, typically at geographically dispersed clinical trial sites, to permit the FDA to evaluate the overall benefit-risk relationship of the drug or biologic and to provide adequate information for the labeling of the product. In most cases, the FDA requires two adequate and well-controlled Phase 3 clinical trials to demonstrate the efficacy of the drug or biologic. A single Phase 3 trial with other confirmatory evidence may be sufficient in rare instances where the study is a large multicenter trial demonstrating internal consistency and a statistically very persuasive finding of a clinically meaningful effect on mortality, irreversible morbidity or prevention of a disease with a potentially serious outcome and confirmation of the result in a second trial would be practically or ethically impossible.

After completion of the required clinical testing, an NDA or BLA is prepared and submitted to the FDA. FDA approval of the NDA or BLA is required before marketing of the product may begin in the United States. The NDA or BLA must include the results of all preclinical, clinical, and other testing and a compilation of data relating to the product’s pharmacology, chemistry, manufacture, and controls. The cost of preparing and submitting an NDA or BLA is substantial. The submission of most NDAs and BLAs is additionally subject to a substantial application user fee, currently exceeding $2.9 million, and the manufacturer and/or sponsor under an approved new drug application are also subject to an annual program fee which is currently set at more than $336,000. These fees are typically increased annually.

The FDA undertakes to perform an initial filing review within 60 days from its receipt of an NDA or BLA to determine whether the application will be accepted for filing based on the agency’s threshold determination that it is sufficiently complete to permit substantive review. Once the submission is accepted for filing, the FDA begins an in-depth review. The FDA has agreed to certain performance goals in the review of NDAs and BLAs. Most such applications for standard review drug or biologic products are reviewed within ten to twelve months; most applications for priority review drugs or

Table of Contents

biologics are reviewed in six to eight months. The FDA can extend these reviews by three months. Priority review can be applied to drugs that the FDA determines offer major advances in treatment, or provide a treatment where no adequate therapy exists. For biologics, priority review is further limited only for products intended to treat a serious or life-threatening disease relative to the currently approved products. The review process for both standard and priority review may be extended by the FDA for three additional months to consider certain late-submitted information, or information intended to clarify information already provided in the submission.

The FDA may also refer applications for novel drug or biologic products, or drug or biologic products that present difficult questions of safety or efficacy, to an advisory committee – typically a panel that includes clinicians and other experts – for review, evaluation, and a recommendation as to whether the application should be approved. The FDA is not bound by the recommendation of an advisory committee, but it generally follows such recommendations. Before approving an NDA or BLA, the FDA will typically inspect one or more clinical sites to assure compliance with GCP. Additionally, the FDA will inspect the facility or the facilities at which the drug is manufactured. FDA will not approve the product unless compliance with current good manufacturing practice, or cGMP, is satisfactory and the NDA or BLA contains data that provide substantial evidence that the drug or biologic is safe and effective in the indication studied.

After the FDA evaluates the NDA or BLA and the manufacturing facilities, it issues either an approval letter or a complete response letter. A complete response letter generally outlines the deficiencies in the submission and may require substantial additional testing, or information, in order for the FDA to reconsider the application. If, or when, those deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the NDA or BLA, the FDA will issue an approval letter. The FDA has committed to reviewing such resubmissions in two or nine months depending on the type of information included.

An approval letter authorizes commercial marketing of the drug or biologic with specific prescribing information for specific indications. As a condition of NDA or BLA approval, the FDA may require a risk evaluation and mitigation strategy, or REMS, to help ensure that the benefits of the drug or biologic outweigh the potential risks. REMS can include medication guides, communication plans for healthcare professionals, and elements to assure safe use, or ETASU. ETASU can include, but are not limited to, special training or certification for prescribing or dispensing, dispensing only under certain circumstances, special monitoring, and the use of patient registries. The requirement for a REMS can materially affect the potential market and profitability of the product. Moreover, product approval may require substantial post-approval testing and surveillance to monitor the product’s safety or efficacy. Once granted, product approvals may be withdrawn if compliance with regulatory standards is not maintained or problems are identified following initial marketing.

Changes to some of the conditions established in an approved application, including changes in indications, labeling, or manufacturing processes or facilities, require submission and FDA approval of a new NDA or BLA or NDA or BLA supplement before the change can be implemented. An NDA or BLA supplement for a new indication typically requires clinical data similar to that in the original application, and the FDA uses the same procedures and actions in reviewing NDA or BLA supplements as it does in reviewing NDAs or BLAs.

Post-Approval Requirements

Any products for which we receive FDA approvals are subject to continuing regulation by the FDA, including, among other things, record-keeping requirements, reporting of adverse experiences with the product, providing the FDA with updated safety and efficacy information, product sampling and distribution requirements, and complying with FDA promotion and advertising requirements, which include, among others, standards for direct-to-consumer advertising, restrictions on promoting products for uses or in patient populations that are not described in the product’s approved uses, known as ’off-label’ use, limitations on industry-sponsored scientific and educational activities, and requirements for promotional activities involving the internet. Although physicians may prescribe legally available products for off-label uses, if the physicians deem to be appropriate in their professional medical judgment, manufacturers may not market or promote such off-label uses.

In addition, quality control and manufacturing procedures must continue to conform to applicable manufacturing requirements after approval to ensure the long-term stability of the product. cGMP regulations require among other things, quality control and quality assurance as well as the corresponding maintenance of records and documentation and the

Table of Contents

obligation to investigate and correct any deviations from cGMP. Manufacturers and other entities involved in the manufacture and distribution of approved products are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain cGMP compliance. Discovery of problems with a product after approval may result in restrictions on a product, manufacturer, or holder of an approved BLA, including, among other things, recall or withdrawal of the product from the market. In addition, changes to the manufacturing process are strictly regulated, and depending on the significance of the change, may require prior FDA approval before being implemented. Other types of changes to the approved product, such as adding new indications and claims, are also subject to further FDA review and approval.

The FDA also may require post-marketing testing, known as Phase 4 testing, and surveillance to monitor the effects of an approved product. Discovery of previously unknown problems with a product or the failure to comply with applicable FDA requirements can have negative consequences, including adverse publicity, judicial or administrative enforcement, warning letters from the FDA, mandated corrective advertising or communications with doctors, and civil or criminal penalties, among others. Newly discovered or developed safety or effectiveness data may require changes to a product’s approved labeling, including the addition of new warnings and contraindications, and also may require the implementation of other risk management measures. Also, new government requirements, including those resulting from new legislation, may be established, or the FDA’s policies may change, which could delay or prevent regulatory approval of our product candidates under development.

Additional Controls for Biologics

To help reduce the increased risk of the introduction of adventitious agents, the PHSA emphasizes the importance of manufacturing controls for products whose attributes cannot be precisely defined. The PHSA also provides authority to the FDA to immediately suspend licenses in situations where there exists a danger to public health, to prepare or procure products in the event of shortages and critical public health needs, and to authorize the creation and enforcement of regulations to prevent the introduction or spread of communicable diseases in the United States and between states.

After a BLA is approved, the product may also be subject to official lot release as a condition of approval. As part of the manufacturing process, the manufacturer is required to perform certain tests on each lot of the product before it is released for distribution. If the product is subject to official release by the FDA, the manufacturer submits samples of each lot of product to the FDA together with a release protocol showing a summary of the history of manufacture of the lot and the results of all of the manufacturer’s tests performed on the lot. The FDA may also perform certain confirmatory tests on lots of some products, such as viral vaccines, before releasing the lots for distribution by the manufacturer. In addition, the FDA conducts laboratory research related to the regulatory standards on the safety, purity, potency, and effectiveness of biological products. As with drugs, after approval of biologics, manufacturers must address any safety issues that arise, are subject to recalls or a halt in manufacturing, and are subject to periodic inspection after approval.

Cell and Tissue-Based Biologics

Establishments that manufacture cell and tissue-based products must comply with the FDA’s current good tissue practices, or cGTP, which are FDA regulations that govern the methods used in, and the facilities and controls used for, the manufacture of such products. The primary intent of the cGTP requirements is to ensure that cell- and tissue-based products are manufactured in a manner designed to prevent the introduction, transmission and spread of communicable disease. FDA regulations also include requirements for a unified registration and listing system, donor screening and testing, adverse reaction reporting, and labeling.

Cell and tissue-based products may also be subject to the same approval standards, including demonstration of safety and efficacy, as other biologic and drug products if they meet certain criteria such as if the cells or tissues are more than minimally manipulated or if they are intended for a non-homologous use. Products manufactured using the ImPACT^® technology meet this threshold and therefore are considered biological drugs. Manufacture of ImPACT^® products are subject to both cGTP and cGMP regulations for manufacturing quality. Marketing of these products in the United States will require FDA approval under the BLA pathway as discussed above.

Other U.S. Healthcare Laws and Compliance Requirements

In the United States, our activities are potentially subject to regulation by various federal, state and local authorities in addition to the FDA, including but not limited to, the Centers for Medicare and Medicaid Services, or CMS, other divisions of the U.S. Department of Health and Human Services, for instance the Office of Inspector General, the U.S. Department of Justice, or DOJ, and individual U.S. Attorney offices within the DOJ, and state and local governments. For example, sales, marketing and scientific/educational grant programs must comply with the anti-fraud and abuse provisions of the Social Security Act, the false claims laws, the physician payment transparency laws, the privacy and security provisions of HIPAA, as amended by HITECH, and similar state laws, each as amended.

The federal anti-kickback statute prohibits, among other things, any person or entity, from knowingly and willfully offering, paying, soliciting or receiving any remuneration, directly or indirectly, overtly or covertly, in cash or in kind, to induce or in return for purchasing, leasing, ordering or arranging for the purchase, lease or order of any item or service reimbursable under Medicare, Medicaid or other federal healthcare programs. The term remuneration has been interpreted broadly to include anything of value. The anti-kickback statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers, and formulary managers on the other. There are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution. The exceptions and safe harbors are drawn narrowly and practices that involve remuneration that may be alleged to be intended to induce prescribing, purchasing or recommending may be subject to scrutiny if they do not qualify for an exception or safe harbor. Our practices may not in all cases meet all of the criteria for protection under a statutory exception or regulatory safe harbor. Failure to meet all of the requirements of a particular applicable statutory exception or regulatory safe harbor, however, does not make the conduct per se illegal under the anti-kickback statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all of its facts and circumstances. Violations of this law are punishable by imprisonment, criminal fines, administrative civil money penalties and exclusion from participation in federal healthcare programs.

Additionally, the intent standard under the anti-kickback statute was amended by the Affordable Care Act to a stricter standard such that a person or entity no longer needs to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. In addition, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively the ACA, provides that the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act., as discussed below.

The civil monetary penalties statute imposes penalties against any person or entity that, among other things, is determined to have presented or caused to be presented a claim to a federal health program that the person knows or should know is for an item or service that was not provided as claimed or is false or fraudulent.

Although we would not submit claims directly to payors, drug manufacturers can be held liable under the federal civil False Claims Act, which imposes civil penalties, including through civil whistleblower or qui tam actions, against individuals or entities (including manufacturers) for, among other things, knowingly presenting, or causing to be presented to federal programs (including Medicare and Medicaid) claims for items or services, including drugs, that are false or fraudulent, claims for items or services not provided as claimed, or claims for medically unnecessary items or services; making a false statement or record material to payment of a false claim; or avoiding, decreasing or concealing an obligation to pay money to the federal government. Penalties for a False Claims Act violation include three times the actual damages sustained by the government, plus mandatory civil penalties for each separate false claim, the potential for exclusion from participation in federal healthcare programs and, although the federal False Claims Act is a civil statute, conduct that results in a False Claims Act violation may also implicate various federal criminal statutes. The government may deem manufacturers to have “caused” the submission of false or fraudulent claims by, for example, providing inaccurate billing or coding information to customers or promoting a product off-label. Claims which include items or services resulting from a violation of the federal Anti-Kickback Statute are false or fraudulent claims for purposes of the False Claims Act. Our future marketing and activities relating to the reporting of wholesaler or estimated retail prices for our products, if approved, the reporting of prices used to calculate Medicaid rebate information and other information affecting federal, state and third-party reimbursement for our products, and the sale and marketing of our product and any future product candidates, are subject to scrutiny under this law. Pharmaceutical and other healthcare companies have been prosecuted

Table of Contents

under these laws for allegedly providing free product to customers with the expectation that the customers would bill federal programs for the product. Other companies have been prosecuted for causing false claims to be submitted because of the companies’ marketing of the product for unapproved, and thus non-reimbursable, uses.

HIPAA created new federal criminal statutes that prohibit knowingly and willfully executing, or attempting to execute, a scheme to defraud or to obtain, by means of false or fraudulent pretenses, representations or promises, any money or property owned by, or under the control or custody of, any healthcare benefit program, including private third-party payors and knowingly and willfully falsifying, concealing or covering up by trick, scheme or device, a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the federal anti-kickback statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.

We may be subject to data privacy and security regulations by both the federal government and the states in which we conduct business. HIPAA, as amended by the HITECH Act, and their respective implementing regulations. Among other things, HITECH makes HIPAA’s privacy and security standards directly applicable to business associates, defined as independent contractors or agents of covered entities, which include health care providers, health plans, and healthcare clearinghouse, that create, receive, or obtain protected health information in connection with providing a service on behalf of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities and business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorney’s fees and costs associated with pursuing federal civil actions. In addition, certain state laws govern the privacy and security of health information in specified circumstances, some of which are more stringent and many of which differ from each other in significant ways, thus complicating compliance efforts. Failure to comply with these laws, where applicable, can result in the imposition of significant civil and criminal penalties.

Additionally, the Federal Physician Payments Sunshine Act under the ACA, and its implementing regulations, require that certain manufacturers of drugs, devices, biological and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to annually report to the Centers for Medicare and Medicaid, or CMS, information related to certain payments or other transfers of value made or distributed to physicians and teaching hospitals, or to entities or individuals at the request of, or designated on behalf of, the physicians and teaching hospitals and to report annually certain ownership and investment interests held by physicians and their immediate family members. Failure to submit timely, accurately, and completely the required information may result in civil monetary penalties. Certain states also mandate implementation of compliance programs, impose restrictions on pharmaceutical manufacturer marketing practices and/or require the tracking and reporting of gifts, compensation and other remuneration to healthcare providers and entities.

In order to distribute products commercially, we must also comply with state laws that require the registration of manufacturers and wholesale distributors of drug and biological products in a state, including, in certain states, manufacturers and distributors who ship products into the state even if such manufacturers or distributors have no place of business within the state. Some states also impose requirements on manufacturers and distributors to establish the pedigree of product in the chain of distribution, including some states that require manufacturers and others to adopt new technology capable of tracking and tracing product as it moves through the distribution chain. Several states have enacted legislation requiring pharmaceutical and biotechnology companies to establish marketing compliance programs, file periodic reports with the state, make periodic public disclosures on sales, marketing, pricing, clinical trials and other activities, and/or register their sales representatives, as well as to prohibit pharmacies and other healthcare entities from providing certain physician prescribing data to pharmaceutical and biotechnology companies for use in sales and marketing, and to prohibit certain other sales and marketing practices. All of our activities are potentially subject to federal and state consumer protection and unfair competition laws.

If our operations are found to be in violation of any of the federal and state healthcare laws described above or any other governmental regulations that apply to it, we may be subject to penalties, including without limitation, significant civil, criminal and/or administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in government programs, such as Medicare and Medicaid, injunctions, private “qui tam” actions brought by individual whistleblowers in the name of the government, or refusal to enter into government contracts, contractual damages,

reputational harm, administrative burdens, diminished profits and future earnings, and the curtailment or restructuring of operations, any of which could adversely affect our ability to operate our business and our results of operations. If any of the physicians or other healthcare providers or entities with whom we expect to do business is found to be not in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs. Ensuring business arrangements comply with applicable healthcare laws, as well as responding to possible investigations by government authorities, can be time- and resource-consuming and can divert a company’s attention from the business.

Coverage, Pricing and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any product candidates for which we obtain regulatory approval. In the United States and markets in other countries, sales of any products for which we receive regulatory approval for commercial sale will depend, in part, on the extent to that third-party payors provide coverage, and establish adequate reimbursement levels for such products. In the United States, third-party payors include federal and state healthcare programs, private managed care providers, health insurers and other organizations. The process for determining whether a third-party payor will provide coverage for a product may be separate from the process for setting the price of a product or for establishing the reimbursement rate that such a payor will pay for the product. Third-party payors may limit coverage to specific products on an approved list, also known as a formulary, which might not include all of the FDA-approved products for a particular indication. Third-party payors are increasingly challenging the price, examining the medical necessity and reviewing the cost- effectiveness of medical products, therapies and services, in addition to questioning their safety and efficacy. We may need to conduct expensive pharmaco-economic studies in order to demonstrate the medical necessity and cost-effectiveness of our product candidates, in addition to the costs required to obtain the FDA approvals. Our product candidates may not be considered medically necessary or cost-effective. A payor’s decision to provide coverage for a product does not imply that an adequate reimbursement rate will be approved. Further, one payor’s determination to provide coverage for a product does not assure that other payors will also provide coverage for the product. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on investment in product development.

Different pricing and reimbursement schemes exist in other countries. Some jurisdictions operate positive and negative list systems under which products may only be marketed once a reimbursement price has been agreed. To obtain reimbursement or pricing approval, some of these countries may require the completion of clinical trials that compare the cost-effectiveness of a particular product candidate to currently available therapies. Other countries allow companies to fix their own prices for medicines but monitor and control company profits. The downward pressure on health care costs has become very intense. As a result, increasingly high barriers are being erected to the entry of new products. In addition, in some countries, cross-border imports from low-priced markets exert a commercial pressure on pricing within a country.

The marketability of any product candidate for which we receive regulatory approval for commercial sale may suffer if the government and third-party payors fail to provide adequate coverage and reimbursement. In addition, emphasis on managed care in the United States has increased and we expect the pressure on healthcare pricing will continue to increase. Coverage policies and third-party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

U.S. Healthcare Reform

In the United States and some foreign jurisdictions, there have been, and likely will continue to be, a number of legislative and regulatory changes and proposed changes regarding the healthcare system directed at broadening the availability of healthcare, improving the quality of healthcare, and containing or lowering the cost of healthcare.

Some of the provisions of the ACA have yet to be fully implemented, while certain provisions have been subject to judicial and Congressional challenges. It is unclear how these challenges and other efforts to repeal and replace the ACA will impact our business in the future.

Table of Contents

Other legislative changes have been proposed and adopted in the United States since the ACA was enacted. Additionally, there have been several recent U.S. Congressional inquiries and proposed bills designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs and reform government program reimbursement methodologies for drugs.

We cannot predict what healthcare reform initiatives may be adopted in the future. Further federal, state and foreign legislative and regulatory developments are likely, and we expect ongoing initiatives to increase pressure on drug pricing. Such reforms could have an adverse effect on anticipated revenues from product candidates and may affect our overall financial condition and ability to develop product candidates.

We anticipate that current and future U.S. legislative healthcare reforms may result in additional downward pressure on the price that we receive for any approved product, if covered, and could seriously harm our business. Any reduction in reimbursement from Medicare and other government programs may result in a similar reduction in payments from private payors.

Non-U.S. Regulation

Before our products can be marketed outside of the United States, they are subject to regulatory approval of the respective authorities in the country in which the product should be marketed. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary widely from country to country. No action can be taken to market any product in a country until an appropriate application has been approved by the regulatory authorities in that country. The current approval process varies from country to country, and the time spent in gaining approval varies from that required for FDA approval. In certain countries, the sales price of a product must also be approved. The pricing review period often begins after market approval is granted. Even if a product is approved by a regulatory authority, satisfactory prices might not be approved for such product.

In Europe, marketing authorizations may be submitted at a centralized, a decentralized or national level; however, the centralized procedure is mandatory for the approval of biotechnology products and provides for the grant of a single marketing authorization that is valid in all European Union member states. There can be no assurance that the chosen regulatory strategy will secure regulatory approval on a timely basis or at all.

While we intend to market our products outside the United States in compliance with our respective license agreements, we have not made any applications with non-U.S. authorities and have no timeline for such applications or marketing.

Research and Development

We have built an internal and external research and development organization that includes expertise in discovery research, preclinical development, product formulation, analytical chemistry, manufacturing, clinical development and regulatory and quality assurance. Sponsors of clinical trials of FDA-regulated products, including drugs, are required to register and disclose certain clinical trial information. Our cancer trials have been registered on clinicaltrials.gov. Information related to the product, patient population, phase of investigation, study sites and investigators, and other aspects of the clinical trial is then made public as part of the registration. Sponsors are also obligated to discuss the results of their clinical trials after completion. Disclosure of the results of these trials can be delayed until the new product or new indication being studied has been approved. Competitors may use this publicly available information to gain knowledge regarding the progress of development. Research and development expenses were $12.9 million during both years ended December 31, 2020 and 2019, respectively.

Emerging Growth Company

As of January 1, 2019, we were no longer an emerging growth company under the Jumpstart Our Business Startups Act enacted in April 2012 (“JOBS ACT”).

As an emerging growth company, we were subject to reduced public company reporting requirements and were exempt from Section 404(b) of Sarbanes Oxley. Section 404(a) requires issuers to publish information in their annual reports

Table of Contents

concerning the scope and adequacy of the internal control structure and procedures for financial reporting. This statement shall also assess the effectiveness of such internal controls and procedures. Section 404(b) requires that the registered accounting firm shall, in the same report, attest to and report on the assessment on the effectiveness of the internal control structure and procedures for financial reporting.

As an emerging growth company, we were also exempt from Section 14A(a) and (b) of the Exchange Act, which require stockholder approval, on an advisory basis, of executive compensation and golden parachutes.

References to Heat Biologics also include references to our subsidiaries Heat Biologics I, Inc. (“Heat I”), Heat Biologics III, Inc. (“Heat III”), Heat Biologics IV, Inc. (“Heat IV”), Heat Biologics GmbH, Heat Biologics Australia Pty Ltd., Zolovax Inc., and Pelican, unless otherwise indicated. On May 30, 2012, we formed two wholly-owned subsidiaries, Heat Biologics III, Inc. and Heat Biologics IV, Inc. We formed Heat Biologics GmbH (Heat GmbH), a wholly-owned limited liability company, organized in Germany on September 11, 2012 and Heat Biologics Australia Pty LTD, a wholly-owned company, registered in Australia on March 14, 2014. On October 25, 2016, we formed a wholly-owned subsidiary, Zolovax, Inc., to focus on the development of gp96 based vaccines targeting Zika, HIV, West Nile, dengue, yellow fever, and SARS-CoV-2. In June 2012, we divested our 92.5% interest in Pelican (formerly known as Heat Biologics II, Inc.). On April 28, 2017, we completed the acquisition of an 80% controlling interest in Pelican, a related party prior to acquisition. In October 2018, we entered into an agreement with UM whereby UM exchanged its shares of stock in Heat’s subsidiaries, Heat I, Inc. and Pelican, resulting in us owning 100% of Heat I, Inc. and increasing its controlling ownership in Pelican from 80% to 85%. We assigned our proprietary rights related to the development and application of our ImPACT® therapy platform to Heat Biologics I, Inc. In November 2018, we formed Skunkworx Bio, Inc. (formerly known as Delphi Therapeutics, Inc.) which uses a unique and proprietary platform to generate new biological entities that we may rapidly advance into clinical development. Also, in November 2018, we formed Scorpion Biological Services, Inc. (“Scorpion”) (formerly known as Scorpion Biosciences, Inc.), to focus on developing bioanalytic, process development and manufacturing capability to service our in-house requirements as well as potentially those of others. In February 2021, we formed Abacus Biotech, Inc., a wholly-owned subsidiary to pursue additional opportunities related to our business.

We are also a “smaller reporting company”, as defined in Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements. We will cease to be a smaller reporting company if we have (i) more than $250 million in market value of our shares held by non-affiliates as of the last business day of our most recently completed second fiscal quarter or (ii) more than $100 million of annual revenues in our most recent fiscal year completed before the last business day of our second fiscal quarter and a market value of our shares held by non-affiliates more than $700 million as of the last business day of our second fiscal quarter.

On December 11, 2020, we effected a one-for-seven- reverse stock split. All per share numbers reflect the one-for seven reverse stock split.

Human Capital

We believe that our success depends upon our ability to attract, develop, retain and motivate key personnel. Our management and scientific teams possess considerable experience in drug discovery, research and development, manufacturing, clinical and regulatory affairs and believe Heat Biologics directly benefits from this experience and industry knowledge. Our research team comprises B.S., M.S. and Ph.D.-level scientists with expertise in oncology, immunology, and molecular biology.

As of December 31, 2020, we had a total of 39 full-time employees, of which 10 are part of our research team located in San Antonio, Texas, 21 are part of our research team located in Morrisville, North Carolina and eight are part of our corporate team. We consider our relationships with our employees to be good. None of our employees is represented by a labor union. We anticipate that we will need to identify, attract, train and retain other highly skilled personnel to pursue our development program. Hiring for such personnel is competitive, and there can be no assurance that we will be able to retain our key employees or attract, assimilate or retain the qualified personnel necessary for the development of our business.

We have no collective bargaining agreements with our employees and have not experienced any work stoppages. We consider our relations with our employees to be good. Although, management continually seeks to add additional talent to its work force, management believes that it has sufficient human capital to operate its business successfully.

Competitive Pay and Benefits. Our compensation programs are designed to align the compensation of our employees with our performance and to provide the proper incentives to attract, retain and motivate employees to achieve superior results. The structure of our compensation programs balances incentive earnings for both short-term and long-term performance. Specifically:

●

we provide employee wages that are competitive and consistent with employee positions, skill levels, experience, knowledge and geographic location;

●

we engage nationally recognized outside compensation and benefits consulting firms to independently evaluate the effectiveness of our executive compensation and benefit programs and to provide benchmarking against our peers within the industry;

●

we align our executives’ long-term equity compensation with our shareholders’ interests by linking realizable pay with stock performance;

●

annual increases and incentive compensation are based on merit, which is communicated to employees at the time of hiring and documented through our talent management process as part of our annual review procedures and upon internal transfer and/or promotion; and

●

all employees are eligible for health insurance, paid and unpaid leaves, a 401K retirement plan with employer matching contributions (maximum of 4% match) and life and disability/accident coverage. We also offer a variety of voluntary benefits that allow employees to select the options that meet their needs, including flexible time-off, telemedicine, and paid parental leave.

Health and Safety

The health and safety of our employees is our highest priority, and this is consistent with our operating philosophy. Accordingly, with the global spread of the ongoing novel coronavirus pandemic, we have implemented plans designed to address and mitigate the impact of the COVID-19 pandemic on the safety of our employees and our business, which include:

●

adding work from home flexibility;

Table of Contents

●

adjusting attendance policies to encourage those who are sick to stay home ;

●

increasing cleaning protocols across all locations; and

●

initiating regular communication regarding impacts of the COVID-19 pandemic, including health and safety protocols and procedures.

Item 1A. Risk Factors

Investors should carefully consider the risks described below before deciding whether to invest in our securities. If any of the following risks actually occur, our business, financial condition or results of operations could be adversely affected. In such case, the trading price of our common stock could decline and you could lose all or part of your investment. Our actual results could differ materially from those anticipated in the forward-looking statements made throughout this Annual Report a result of different factors, including the risks we face described below.

Risks Relating to our Company, Financial Position and Capital Requirements

We have had limited operations to date.

We are a clinical stage company and have had limited operations to date as have our subsidiaries. We have yet to demonstrate our ability to overcome the risks frequently encountered in our industry and are still subject to many of the risks common to such enterprises, including our ability to implement our business plan, market acceptance of our proposed business and products, under-capitalization, cash shortages, limitations with respect to personnel, financing and other resources, competition from better funded and experienced companies, and uncertainty of our ability to generate revenues. There is no assurance that our activities will be successful or will result in any revenues or profit, and the likelihood of our success must be considered in light of the stage of our development. To date, we have not generated any revenue from product sales and substantially all of our revenue to date has been grant revenue that Pelican has received from CPRIT and a small amount of revenue from a research funding agreement. Even if we generate revenue from product sales, which is not anticipated for several years, if at all, there can be no assurance that we will be profitable. In addition, no assurance can be given that we will be able to consummate our business strategy and plans, or that financial, technological, market, or other limitations may force us to modify, alter, significantly delay, or significantly impede the implementation of such plans. We have insufficient results for investors to use to identify historical trends. Investors should consider our prospects in light of the risk, expenses and difficulties we will encounter as an early stage company. Our revenue and income potential is unproven and our business model is continually evolving. We are subject to the risks inherent to the operation of a new business enterprise and cannot assure you that we will be able to successfully address these risks.

We have a limited operating history upon which to evaluate our ability to commercialize our products.

We are a clinical stage company and our success is dependent upon our ability to obtain regulatory approval for and commercialize our products and we have not demonstrated an ability to perform the functions necessary for the approval or successful commercialization of any product candidates. The successful commercialization of any product candidates will require us to perform a variety of functions, including:

●

continuing to undertake preclinical development and successfully enroll patients in clinical trials;

●

participating in regulatory approval processes;

●

formulating and manufacturing products; and

●

conducting sales and marketing activities.

While various members of our management and staff have prior significant experience in conducting cancer trials, our company, to date, has not successfully completed any pivotal clinical trials and we have limited experience conducting and enrolling patients in clinical trials. Until the last few years, our operations, including the operations and those of our subsidiaries, have been limited primarily to organizing and staffing, acquiring, developing and securing our proprietary technology and undertaking preclinical trials and preparing for and conducting our Phase 1 and Phase 2 clinical and

Table of Contents

preclinical trials of our product candidates. These operations provide a limited basis for you to assess our ability to commercialize our product candidates and the advisability of investing in our securities.

We have incurred net losses every year since our inception and expect to continue to generate operating losses and experience negative cash flows and it is uncertain whether we will achieve profitability.

For the years ended December 31, 2020 and 2019, we incurred a net loss of $26.4 million and $20.4 million, respectively. We have an accumulated deficit of $130.6 million through December 31, 2020. We expect to continue to incur operating losses until such time, if ever, as we are able to achieve sufficient levels of revenue from operations. Our ability to achieve profitability will depend on us obtaining regulatory approval for our product candidates and market acceptance of our product offerings and our capacity to develop, introduce and sell our products to our targeted markets. There can be no assurance that any of our product candidates will be approved for commercial sale, or even if our product candidates are approved for commercial sale that we will ever generate significant sales or achieve profitability. Accordingly, the extent of future losses and the time required to achieve profitability, if ever, cannot be predicted at this point.

Even if we succeed in developing and commercializing one or more product candidates, we expect to incur substantial losses for the foreseeable future and may never become profitable. We also expect to continue to incur significant operating expenses and anticipate that our expenses will increase substantially in the foreseeable future as we:

●

continue to undertake preclinical development and conduct clinical trials for product candidates;

●

seek regulatory approvals for product candidates;

●

implement additional internal systems and infrastructure; and

●

hire additional personnel.

We also expect to experience negative cash flows for the foreseeable future as we fund our operating losses. As a result, we will need to generate significant revenues or raise additional financing in order to achieve and maintain profitability. We may not be able to generate these revenues or achieve profitability in the future. Our failure to achieve or maintain profitability would likely negatively impact the value of our securities and financing activities.

We may need to raise additional capital to support our long-term business plans and our failure to obtain funding when needed may force us to delay, reduce or eliminate our development programs or commercialization efforts.

During the year ended December 31, 2020, our operating activities used net cash of approximately $22.0 million and as of December 31, 2020, our cash and cash equivalents and short-term investments were approximately $111.8 million. During the year ended December 31, 2019, our operating activities used net cash of approximately $12.8 million and as of December 31, 2019 our cash and cash equivalents and short-term investments were approximately $14.8 million. We have experienced significant losses since inception and have a significant accumulated deficit. As of December 31, 2020, our accumulated deficit totaled $130.6 million and as of December 31, 2019, our accumulated deficit totaled $104.6 million on a consolidated basis. We expect to incur additional operating losses in the future and therefore expect our cumulative losses to increase. We do not expect to derive revenue from any of our product candidates in the near future until we or our potential partners successfully commercialize our products. We expect our expenses to increase if and when we initiate and conduct Phase 3 and other clinical trials and seek marketing approval for our product candidates. Until such time as we receive approval from the FDA and other regulatory authorities for our product candidates, we will not be permitted to sell our products and therefore will not have product revenues from the sale of products.

We will need to raise additional capital to fund our long term operations and milestone payments and we cannot be certain that funding will be available to us on acceptable terms on a timely basis, or at all. To meet our financing needs, we are considering multiple alternatives, including, but not limited to, additional equity financings, which we expect will include sales of common stock through at the market issuances, debt financings and/or funding from partnerships or collaborations. Our ability to raise capital through the sale of securities may be limited by our number of authorized shares of common stock and various rules of the SEC and the Nasdaq Capital Market that place limits on the number and dollar amount of securities that we may sell. Any additional sources of financing will likely involve the issuance of our equity or debt securities, which will have a dilutive effect on our stockholders, assuming we are able to sufficiently increase our authorized number of shares of common stock. To the extent that we raise additional funds by issuing equity securities,

Table of Contents

our stockholders may experience significant dilution. Any debt financing, if available, may involve restrictive covenants that may impact our ability to conduct our business. If we fail to raise additional funds on acceptable terms, we may be unable to complete planned preclinical and clinical trials or obtain approval of our product candidates from the FDA and other regulatory authorities or continue to maintain our listing on the Nasdaq Capital Market. In addition, we could be forced to delay, discontinue or curtail product development, forego sales and marketing efforts, and forego licensing in attractive business opportunities. Any additional sources of financing will likely involve the issuance of our equity or debt securities, which will have a dilutive effect on our stockholders.

Global health crises may adversely affect our planned operations.

Our business and the business of the supplier of our clinical product candidate and the suppliers of the standard of care drugs that are administered in combination with our clinical product candidate could be materially and adversely affected by the risks, or the public perception of the risks, related to a pandemic or other health crisis, such as the recent outbreak of novel coronavirus (COVID-19). A significant outbreak of contagious diseases in the human population could result in a widespread health crisis that could adversely affect our planned operations. Such events could result in the complete or partial closure of one or more manufacturing facilities which could impact our supply of our clinical product candidate or the standard of care drugs that are administered in combination with our clinical product candidate. In addition, an outbreak near where our clinical trial sites are located would likely impact our ability to recruit patients, delay our clinical trials, and could affect our ability to complete our clinical trials within the planned time periods. In addition, it could impact economies and financial markets, resulting in an economic downturn that could impact our ability to raise capital or slow down potential partnering relationships.

Coronavirus could adversely impact our business, including our clinical trials.

Since December 2019, a novel strain of coronavirus, COVID-19, has spread to multiple countries, including the United States where we have planned or active clinical trial sites. On March 11, 2020, the World Health Organization declared the outbreak of COVID-19 as a global pandemic. In response to the COVID-19 pandemic, many state, local, and foreign governments have put in place, and others in the future may put in place, quarantines, executive orders, shelter-in-place orders, and similar government orders and restrictions in order to control the spread of the disease. Such orders or restrictions, or the perception that such orders or restrictions could occur, have resulted in business closures, work stoppages, slowdowns and delays, work-from-home policies, travel restrictions, and cancellation or postponement of events, among other effects that could negatively impact productivity and disrupt our operations.

As the COVID-19 pandemic continues to spread around the globe, we could experience disruptions that could severely impact our business and clinical trials, including:

●

delays in initiation of or difficulties in enrolling patients in our clinical trials due to a lack of personal protection equipment supply for patients and subsequent temporary cessation of non-essential patient procedures;

●

delays or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff;

●

diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the conduct of our clinical trials;

●

interruption of key clinical trial activities, such as clinical trial site monitoring, due to limitations on travel imposed or recommended by federal or state governments, employers and others;

●

limitations in employee resources that would otherwise be focused on the conduct of our clinical trials, including because of sickness of employees or their families or the desire of employees to avoid contact with large groups of people;

●

delays in receiving approval from local regulatory authorities to initiate our planned clinical trials;

Table of Contents

●

delays in clinical sites receiving the supplies and materials needed to conduct our clinical trials;

●

interruption in global shipping that may affect the transport of clinical trial materials, such as investigational drug product used in our clinical trials;

●

changes in local regulations as part of a response to the COVID-19 outbreak which may require us to change the ways in which our clinical trials are conducted, which may result in unexpected costs, or to discontinue the clinical trials altogether;

●

delays in necessary interactions with local regulators, ethics committees and other important agencies and contractors due to limitations in employee resources or forced furlough of government employees;

●

delay in the timing of interactions with the FDA due to absenteeism by federal employees or by the diversion of their efforts and attention to approval of other therapeutics or other activities related to COVID-19; and

●

refusal of the FDA to accept data from clinical trials in affected geographies outside the United States.

In addition, the COVID-19 outbreak could disrupt our operations due to absenteeism by infected or ill members of management or other employees, or absenteeism by members of management and other employees who elect not to come to work due to the illness affecting others in our office or laboratory facilities, or due to quarantines. COVID-19 illness could also impact members of our Board of Directors resulting in absenteeism from meetings of the directors or committees of directors, and making it more difficult to convene the quorums of the full Board of Directors or its committees needed to conduct meetings for the management of our affairs.

The global outbreak of COVID-19 continues to rapidly evolve. The extent to which the COVID-19 outbreak may impact our business and clinical trials will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the outbreak, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the disease. We do not yet know the full extent of potential delays or impacts on our business, operations, or the global economy as a whole. While the spread of COVID-19 may eventually be contained or mitigated, there is no guarantee that a future outbreak of this or any other widespread epidemics will not occur, or that the global economy will recover, either of which could seriously harm our business.

We currently have no product revenues and may not generate product revenue at any time in the near future, if at all.

We currently have no products for sale and we cannot guarantee that we will ever have any drug products approved for sale. We and our product candidates are subject to extensive regulation by the FDA, and comparable regulatory authorities in other countries governing, among other things, research, testing, clinical trials, manufacturing, labeling, promotion, marketing, adverse event reporting and recordkeeping of our product candidates. Until, and unless, we receive approval from the FDA and other regulatory authorities for our product candidates, we cannot commercialize our product candidates and will not have product revenues. In addition, the technology that we out-licensed is in the early stages of development and there is a low likelihood of success for any such technology at that stage, therefore there can be no assurance that any products will be developed by such licensee or that we will derive any revenue from such licensee. In addition, changes may occur that would consume our available capital at a faster pace than expected, including changes in and progress of our development activities, acquisitions of additional candidates and changes in regulation. Moreover, preclinical studies and clinical trials may not start or be completed as we forecast and may not achieve the desired results. Therefore, we expect that we will seek additional sources of funding, such as additional financing or grant funding, and additional financing may not be available on favorable terms, if at all. Our ability to raise capital through the sale of equity may be limited by the various rules of the Securities and Exchange Commission and the Nasdaq Capital Market that place limits on the number of shares of stock that may be sold. If we do not succeed in raising additional funds on acceptable terms, we may be unable to complete planned preclinical and clinical trials or obtain approval of our product candidates from the FDA and other regulatory authorities. In addition, we could be forced to delay, discontinue or curtail product development, forego sales and marketing efforts, and forego licensing in attractive business opportunities. Any additional sources of

Table of Contents

financing will likely involve the issuance of our equity or debt securities, which will have a dilutive effect on our stockholders.

Our main focus and the investment of a significant portion of our efforts and financial resources has been in the development of our product candidate, HS-110, for which we are currently actively conducting a Phase 2 clinical trial. HS-110, HS-130 and PTX-35 are our only current products in clinical trials. Our other product candidates, including our COVID-19 vaccine, are all at a pre-clinical stage. We expect that at least one Phase 3 clinical trial of HS-110 will be required to gain approval by the FDA. Our future success depends heavily on our ability to successfully manufacture, develop, obtain regulatory approval, and commercialize our product candidates, which may never occur. Before commercializing any product candidate, we will require additional clinical trials and regulatory approvals for which there can be no guarantee that we will be successful. We currently generate no revenues from any of our product candidates, and we may never be able to develop or commercialize a marketable drug.

Our stock price has fluctuated in the past, has recently been volatile and may be volatile in the future, and as a result, investors in our common stock could incur substantial losses and our ability to raise fuds may be impacted.

Our stock price has fluctuated in the past, has recently been volatile and may be volatile in the future. On February 9, 2021, the reported low sale price of our common stock was $11.51 per share and the reported high sales price was $17.00 per share. For comparison purposes, on December 31, 2020, the price of our common stock closed at $5.36 per share. We may incur rapid and substantial decreases in our stock price in the foreseeable future that are unrelated to our operating performance or prospects. In addition, the recent outbreak of the novel strain of coronavirus (COVID-19) has caused broad stock market and industry fluctuations. The stock market generally and the market for biotechnology and pharmaceutical companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, investors may experience losses on their investment in our common stock. The market price for our common stock may be influenced by many factors, including the following:

●

investor reaction to our business strategy;

●

the success of competitive products or technologies;

●

our continued compliance with the listing standards of the Nasdaq Global Select Market;

●

regulatory or legal developments in the United States and other countries, especially changes in laws or regulations applicable to our products;

●

results of our clinical trials;

●

actions taken by regulatory agencies with respect to our products, clinical studies, manufacturing process or sales and marketing terms;

●

variations in our financial results or those of companies that are perceived to be similar to us;

●

the success of our efforts to acquire or in-license additional products or product candidates;

●

developments concerning our collaborations or partners;

●

developments or disputes concerning patents or other proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our products;

●

our ability or inability to raise additional capital and the terms on which we raise it;

●

declines in the market prices of stocks generally;

●

trading volume of our common stock;

●

sales of our common stock by us or our stockholders;

●

general economic, industry and market conditions; and

●

other events or factors, including those resulting from such events, or the prospect of such events, including war, terrorism and other international conflicts, public health issues including health epidemics or pandemics, such as the recent outbreak of the novel coronavirus (COVID-19), and natural disasters such as fire, hurricanes,

Table of Contents

earthquakes, tornados or other adverse weather and climate conditions, whether occurring in the United States or elsewhere, could disrupt our operations, disrupt the operations of our suppliers or result in political or economic instability.

These broad market and industry factors may seriously harm the market price of our common stock, regardless of our operating performance. Since the stock price of our common stock has fluctuated in the past, has been recently volatile and may be volatile in the future, investors in our common stock could incur substantial losses. In the past, following periods of volatility in the market, securities class-action litigation has often been instituted against companies. Such litigation, if instituted against us, could result in substantial costs and diversion of management’s attention and resources, which could materially and adversely affect our business, financial condition, results of operations and growth prospects. There can be no guarantee that our stock price will remain at current prices or that future sales of our common stock will not be at prices lower than those sold to investors.

If our acquired intangible assets become impaired, we may be required to record a significant charge to earnings.

We regularly review acquired intangible assets for impairment when events or changes in circumstances indicate that the carrying value may not be recoverable. We test goodwill and indefinite-lived intangible assets for impairment at least annually. Factors that may be considered a change in circumstances, indicating that the carrying value of the intangible assets may not be recoverable, include: macroeconomic conditions, such as deterioration in general economic conditions; industry and market considerations, such as deterioration in the environment in which we operate; cost factors, such as increases in labor or other costs that have a negative effect on earnings and cash flows; our financial performance, such as negative or declining cash flows or a decline in actual or planned revenue or earnings compared with actual and projected results of relevant prior periods; other relevant entity-specific events, such as changes in management, key personnel, strategy, or customers; and sustained decreases in share price. During the year ended December 31, 2019, we recorded a non-cash goodwill impairment charge of $737,000.

Risks Related to Our Clinical Development, Regulatory Approval and Commercialization

If we experience delays in the enrollment of patients in our clinical trials, our receipt of necessary regulatory approvals could be delayed or prevented.

Our inability to locate and enroll a sufficient number of eligible patients in our clinical trials for any of our current or future clinical trials, would result in significant delays or may require us to abandon one or more clinical trials. Our ability to enroll patients in trials is affected by many factors out of our control, including the size and nature of the patient population, the proximity of patients to clinical sites, the eligibility criteria for the trial, the design of the clinical trial, competing clinical trials, and clinicians’ and patients’ perceptions as to the potential advantages of the drug being studied in relation to other available therapies, including any new drugs that may be approved for the indications we are investigating. As we seek to advance our clinical programs, we remain in close contact with our CROs and clinical sites and intend to monitor and assess the impact of COVID-19 on our studies, current timelines and the costs of our studies. The rapid development and fluidity of this situation precludes any prediction as to the ultimate adverse impact to us of enrollment in clinical trials, and no assurance can be given that the impact of COVID-19 will not seriously disrupt our ability to enroll patients in our clinical trials.

If we do not obtain the necessary regulatory approvals in the United States and/or other countries, we will not be able to sell our product candidates.

We cannot assure you that we will receive the approvals necessary to commercialize any of our product candidates or any product candidates we acquire or develop in the future. We will need FDA approval to commercialize our product candidates in the United States and approvals from the FDA-equivalent regulatory authorities in foreign jurisdictions to commercialize our product candidates in those jurisdictions. In order to obtain FDA approval of any product candidate, we must submit to the FDA a BLA, demonstrating that the product candidate is safe, pure and potent, or effective for its intended use. This demonstration requires significant research including preclinical studies, as well as clinical trials. Satisfaction of the FDA’s regulatory requirements typically takes many years, depends upon the type, complexity and novelty of the product candidate and requires substantial resources for research, development and testing. We cannot

Table of Contents

predict whether our clinical trials will demonstrate the safety and efficacy of our product candidates or if the results of any clinical trials will be sufficient to advance to the next phase of development or for approval from the FDA. We also cannot predict whether our research and clinical approaches will result in drugs or therapeutics that the FDA considers safe and effective for the proposed indications. The FDA has substantial discretion in the drug approval process. The approval process may be delayed by changes in government regulation, future legislation or administrative action or changes in FDA policy that occur prior to or during our regulatory review. Delays in obtaining regulatory approvals may:

●

prevent or delay commercialization of, and our ability to derive product revenues from, our product candidates; and

●

diminish any competitive advantages that we may otherwise believe that we hold.

Even if we comply with all FDA requests, the FDA may ultimately reject one or more of our BLAs. We may never obtain regulatory clearance for any of our product candidates. Failure to obtain FDA approval of any of our product candidates will severely undermine our business by leaving us without a saleable product, and therefore without any source of revenues, until another product candidate can be developed. There is no guarantee that we will ever be able to develop or acquire another product candidate.

In addition, the FDA may require us to conduct additional preclinical and clinical testing or to perform post-marketing studies, as a condition to granting marketing approval of a product. Regulatory approval of oncology products often requires that patients in clinical trials be followed for long periods to assess their overall survival. The results generated after approval could result in loss of marketing approval, changes in product labeling, and/or new or increased concerns about the side effects or efficacy of a product. The FDA has significant post-market authority, including the explicit authority to require post-market studies and clinical trials, labeling changes based on new safety information, and compliance with FDA-approved risk evaluation and mitigation strategies. The FDA’s exercise of its authority has in some cases resulted, and in the future, could result, in delays or increased costs during product development, clinical trials and regulatory review, increased costs to comply with additional post-approval regulatory requirements and potential restrictions on sales of approved products.

In foreign jurisdictions, we must also receive approval from the appropriate regulatory authorities before we can commercialize any vaccines. Foreign regulatory approval processes generally include all of the risks associated with the FDA approval procedures described above. There can be no assurance that we will receive the approvals necessary to commercialize our product candidates for sale outside the United States.

Our product candidates are in early stages of development, and therefore they will require extensive preclinical and clinical testing.

Because our product candidates are in early stages of development, they will require extensive preclinical and clinical testing. HS-110, HS-130 and PTX-35 are our only current product candidates in clinical trials and our other product candidates are all in the preclinical stage of development. Although we have completed enrollment for a Phase 2 clinical trial for HS-110 and a Phase 1 clinical trial of HS-130, we cannot predict with any certainty if or when we might submit a BLA for regulatory approval for any of our product candidates or whether any such BLA will be accepted for review by the FDA, or whether any BLA will be approved upon review.

Even if our clinical trials are completed as planned, we cannot be certain that their results will support our proposed indications. Success in preclinical testing and early clinical trials does not ensure that later clinical trials will be successful, and we cannot be sure that the results of later clinical trials will replicate the results of prior clinical trials and preclinical testing. The results reported for our initial 76 patients in our Phase 1b/2 clinical trial for HS-110 or initial data in our Phase 2 clinical trial for HS-110 may not be replicated with other patients or other clinical trials. For example, the Phase 1 HS-410 clinical trial, as well as the interim data from the Phase 2 HS-410 clinical study, showed evidence of an immune response in NMIBC patients exposed to HS-410, however, the topline data from the Phase 2 clinical trial reported that there was no statistically significant difference in the primary endpoint between the vaccine and placebo arms of the trial. The Phase 2 clinical trial of HS-410 used doses and dosing regimens which had not previously been tested, and combinations with other immunotherapy agents. In addition, immune response is not an acceptable regulatory endpoint for approval, and the HS-410 Phase 1 trial involved a small sample size and was not randomized or blinded. The clinical trial process may fail to demonstrate that our product candidates are safe and effective for their proposed uses. This failure

Table of Contents

could cause us to abandon a product candidate and may delay development of other product candidates. Any delay in, or termination of, our clinical trials will delay and possibly preclude the filing of any BLAs with the FDA and, ultimately, our ability to commercialize our product candidates and generate product revenues.

Our COVID vaccine program is in early stages of development, and therefore will require extensive testing and funding.

We have initiated development of a new COVID-19 vaccine program that utilizes the gp96 platform to secrete SARS-CoV-2 antigens. Because our product candidates are in early stages of development, they will require extensive preclinical and clinical testing. In addition, in order to further our COVID-19 vaccine program we will need significant additional funding. To date, we have not yet developed any drug candidates designed to combat infectious diseases. There can be no assurance given that we will be able to successfully develop a vaccine to treat COVID-19 and even if successful, to do so during this pandemic, or be able to secure the additional funding required to further our COVID-19 vaccine program. Although we have retained consultants, including lobbyists, to seek funding for these new programs, there can be no assurance that we will be able to obtain such financing.

Clinical trials are very expensive, time-consuming, and difficult to design and implement.

As part of the regulatory process, we must conduct clinical trials for each product candidate to demonstrate safety and efficacy to the satisfaction of the FDA and other regulatory authorities. The number and design of the clinical trials that will be required varies depending upon product candidate, the condition being evaluated and the trial results themselves. Therefore, it is difficult to accurately estimate the cost of the clinical trials. Clinical trials are very expensive and difficult to design and implement, in part because they are subject to rigorous regulatory requirements. The clinical trial process is also time consuming. We estimate that clinical trials of our product candidates will take at least several years to complete. Furthermore, failure can occur at any stage of the trials, and we could encounter problems that cause us to abandon or repeat clinical trials. The commencement and completion of clinical trials may be delayed or prevented by several factors, including:

●

unforeseen safety issues;

●

failure to determine appropriate dosing;

●

greater than anticipated cost of our clinical trials;

●

failure to demonstrate effectiveness during clinical trials;

●

slower than expected rates of patient recruitment or difficulty obtaining investigators;

●

patient drop-out or discontinuation;

●

inability to monitor patients adequately during or after treatment;

●

third party contractors failing to comply with regulatory requirements or meet their contractual obligations to us in a timely manner;

●

insufficient or inadequate supply or quality of product candidates or other necessary materials to conduct our trials;

●

potential additional safety monitoring, or other conditions required by FDA or comparable foreign regulatory authorities regarding the scope or design of our clinical trials, or other studies requested by regulatory agencies;

●

problems engaging IRBs to oversee trials or in obtaining and maintaining IRB approval of studies;

●

imposition of clinical hold or suspension of our clinical trials by regulatory authorities; and

●

inability or unwillingness of medical investigators to follow our clinical protocols.

In addition, we or the FDA may suspend or terminate our clinical trials at any time if it appears that we are exposing participants to unacceptable health risks or if the FDA finds deficiencies in our IND submissions or the conduct of these trials. Therefore, we cannot predict with any certainty when, if ever, future clinical trials will commence or be completed.

Table of Contents

We are at risk of a clinical hold at any time based on the evaluation of the data and information submitted to the governing regulatory authorities. On February 2, 2016, we received notice from the FDA of a partial clinical hold on our Phase 2 HS-410 clinical trial despite the fact that we did not have a safety concern. The partial clinical hold came after we concluded that the cell line on which HS-410 is based had been previously misidentified. The partial clinical hold was lifted on February 10, 2016. However, if in the future we are delayed in addressing, or unable to address, any FDA concerns, we could be delayed, or prevented, from conducting our clinical trials.

Misidentification of cell lines could impact our clinical development and intellectual property rights.

Our product candidates are based on human cell lines produced by third parties and licensed by us. Cell line characterization and contamination is a known issue in biomedical research. For example, despite standard procedures to identify the origins and characteristics of our cell lines in early 2016 we discovered that the origin of the cell line used in HS-410 was misidentified. The misidentification resulted in the FDA placing our HS-410 Phase 2 clinical trial on partial clinical hold while the FDA reviewed certain updated documentation provided by us related to the misidentification. In the event we were to use a cell line in the future that is also misidentified, the clinical development of the product candidate utilizing the mischaracterized cell line could be materially and adversely affected, we could lose the right to use the cell line and our intellectual property rights relating to our development of product candidates based on that cell line could be materially and adversely affected. Although we have implemented certain additional procedures to properly identify our cell lines, we may not be able to detect that a cell line has been mischaracterized or mislabeled by a third party.

There is uncertainty as to market acceptance of our technology and product candidates.

Even if the FDA approves one or more of our product candidates, the products may not gain broad market acceptance among physicians, healthcare payers, patients, and the medical community. We have conducted our own research into the markets for our product candidates; however, we cannot guarantee market acceptance of our product candidates, if approved, and have somewhat limited information on which to estimate our anticipated level of sales. Our product candidates, if approved, will require patients, healthcare providers and doctors to adopt our technology. Our industry is susceptible to rapid technological developments and there can be no assurance that we will be able to match any new technological advances. If we are unable to match the technological changes in the needs of our customers the demand for our products will be reduced. Acceptance and use of any products we market will depend upon a number of factors including:

●

perceptions by members of the health care community, including physicians, about the safety and effectiveness of our products;

●

limitation on use or warnings required by FDA in our product labeling;

●

cost-effectiveness of our products relative to competing products;

●

convenience and ease of administration;

●

potential advantages of alternative treatment methods;

●

availability of reimbursement for our products from government or other healthcare payers; and

●

effectiveness of marketing and distribution efforts by us and our licensees and distributors, if any.

Because we expect virtually all of our product revenues for the foreseeable future to be generated from sales of our current product candidates, if approved, the failure of these therapeutics to find market acceptance would substantially harm our business and would adversely affect our revenue.

We currently rely upon our gp96 platform for development of many of our product candidates, which if unsuccessful may impact the success of several of our product candidates.

We are currently developing three product candidates HS-110, HS-130 and ZVX-60 based upon our gp96 platform. We expect that a substantial portion of our efforts and expenditures over the next few years will be devoted to our gp96 platform. Accordingly, our business currently depends heavily on the successful development, regulatory approval and commercialization of our gp96 platform, which may not receive regulatory approval or be successfully commercialized even if regulatory approval is received. The research, testing, manufacturing, labeling, approval, sale, marketing and distribution of product candidates are and will remain subject to extensive regulation by the FDA and other regulatory

Table of Contents

authorities in the United States and other countries that each have differing regulations. We are not permitted to market any product in the United States unless and until we receive approval of a BLA, from the FDA, or in any foreign countries unless and until we receive the requisite approval from regulatory authorities in such countries. We have never submitted a BLA to the FDA or comparable applications to other regulatory authorities and do not expect to be in a position to do so for the foreseeable future. Obtaining approval of a BLA is an extensive, lengthy, expensive and inherently uncertain process, and the FDA may delay, limit or deny approval of its product for many reasons.

We face competitive and other risks in our COVID-19 vaccine program.

We have recently announced preclinical testing of a new vaccine program for treatment of certain patients with COVID-19. This SARS-CoV2 disease is extremely challenging and there are many companies addressing COVID-19, both in vaccines and therapeutic treatments, many of which have significantly greater resources and capital than we do and are further along in the clinic than we are. Pfizer-BioNTech, Moderna, and Johnson & Johnson have already developed a COVID-19 vaccine approved for emergency use in the United States and elsewhere, and many more, including several that have progressed further than us, including Oxford-AstraZeneca, Sanofi, Inovio, Takara Bio and Novavax, are in various stages of development, some of which have already received approval for emergency use in some European countries. Various government entities, including the U.S. government, are offering incentives, grants and contracts to encourage additional investment by commercial organizations into preventative and therapeutic agents against coronavirus, which may have the effect of increasing the number of competitors and/or providing advantages to known competitors. The competition for funding research and development in this disease, including grant funding, is intense and there can be no assurance that we will be able to obtain adequate funding to carry out our development plan or that, even if funding is obtained, our vaccine will be effective, timely, and accepted by appropriate regulatory authorities. Accordingly, there can be no assurance that we will be able to successfully establish a competitive market share for our COVID-19 vaccine, if any.

If we cannot compete successfully for market share against other drug companies, we may not achieve sufficient product revenues and our business will suffer.

The market for our product candidates is characterized by intense competition and rapid technological advances. If any of our product candidates receives FDA approval, it will compete with a number of existing and future drugs and therapies developed, manufactured and marketed by others. Existing or future competing products may provide greater therapeutic convenience or clinical or other benefits for a specific indication than our products or may offer comparable performance at a lower cost. If our products fail to capture and maintain market share, we may not achieve sufficient product revenues and our business will suffer.

We will compete against fully integrated pharmaceutical companies and smaller companies that are collaborating with larger pharmaceutical companies, academic institutions, government agencies and other public and private research organizations. Many of these oncology competitors have oncology compounds already approved or in development and there are currently a few approved COVID-19 vaccines. In addition, many of these competitors, either alone or together with their collaborative partners, operate larger research and development programs or have substantially greater financial resources than we do, as well as significantly greater experience in:

●

developing drugs, biologics and other therapies;

●

undertaking preclinical testing and clinical trials;

●

obtaining FDA and other regulatory approvals of drugs, biologics and other therapies;

●

formulating and manufacturing drugs, biologics and other therapies; and

●

launching, marketing and selling drugs, biologics and other therapies.

Our development program partially depends upon third-party researchers who are outside our control.

We are dependent upon independent investigators and collaborators, such as universities and medical institutions, to conduct our clinical trials under agreements with us. These collaborators are not our employees and we cannot control the amount or timing of resources that they devote to our programs. These investigators may not assign as great a priority to our programs or pursue them as diligently as we would if we were undertaking such programs ourselves. If outside

Table of Contents

collaborators fail to devote sufficient time and resources to our development programs, or if their performance is substandard, the approval of our FDA applications, if any, and our introduction of new product candidates, if any, will be delayed if obtained at all. These collaborators may also have relationships with other commercial entities, some of whom may compete with us. If our collaborators assist our competitors at our expense, our competitive position would be harmed.

We rely significantly on third parties to formulate and manufacture our product candidates.

We have developed certain expertise in the formulation, development and/or manufacturing of biologics; however to date we have relied on third parties for substantially all of our manufacturing needs. To date, the selection and initial replication of our biological cell lines used in our trials has been performed by individuals working at third party laboratories over which we have little process or quality control and therefore the process and replication could be subject to human error. We currently lack all of the necessary resources and expertise to formulate or manufacture our own product candidates. The investigational products for our clinical trials are manufactured by our contractors under current good manufacturing practices, (“cGMPs”) and we have entered into agreements with commercial-scale manufacturers for the production and supply of investigational product for additional Phase 2 and Phase 3 clinical trials as well as commercialization. Our agreement with the manufacturer of our HS-110 product expired in October 2019. In addition, the manufacturer of our HS-110 has closed its facility where it manufactured our HS-110 and therefore future manufacture of HS-110 by such manufacturer may require additional regulatory approvals for the new manufacturing site. Any future orders with such manufacturer will be pursuant to the terms of purchase orders unless a new definitive agreement is entered into. If not renegotiated, we may experience longer manufacturing lead times for any purchase orders we place with either such manufacturer under purchase orders or any new manufacturer, especially in light of additional regulatory requirements due to the change in the manufacturing facility. In addition, our manufacturer for many of our other product candidates, do not currently have the capacity to engage in large scale manufacturing of our products and therefore we will be required to engage new manufacturers for many of our current early stage product candidates. Manufacturing considerations which may include, lead time and capacity considerations of our third-party manufacturers to provide clinical supply of our product candidates, could delay our clinical trials. We must also develop and validate a potency assay prior to submission of a license application. Such assays have traditionally proven difficult to develop for cell-based products and must be established prior to initiating any Phase 3 clinical trials. We have performed assay development work at our Texas laboratory to support our clinical needs as well as those of third parties. In an effort to decrease our dependence upon third party manufacturers and enhance efficiency, we are exploring the establishment of process development and manufacturing capability to support our clinical trials and potentially third party manufacturing needs. If any of our current product candidates, or any product candidates we may develop or acquire in the future, receive FDA approval, we will rely on one or more third-party contractors for manufacturing. Our anticipated future reliance on a limited number of third-party manufacturers exposes us to the following risks:

●

We may be unable to renew or renegotiate current agreements on favorable terms or identify manufacturers on acceptable terms or at all because the number of potential manufacturers with appropriate expertise and facilities is limited.

●

If we change manufacturers at any point during the development process or after approval, which for several of our product candidates we expect to be required to do for later stage clinical trials and commercialization, we will be required to demonstrate comparability between the products made by the old and new manufacturers. If we are unable to do so, we may need to conduct additional clinical trials with product manufactured by the new manufacturer. Accordingly, it may be necessary to evaluate the comparability of the HS-110 or our other product candidates produced by the two different manufacturers at some point during the clinical development process.

●

If we change the manufacturer of a product subsequent to the approval of the product, we will need to obtain approval from the FDA of the change in manufacturer. Any such approval would likely require significant testing and expense, and the new manufacturer may be subject to a cGMP inspection prior to approval. Our third-party manufacturers might be unable to formulate and manufacture our product candidates in the volume and with the quality required to meet our clinical needs and commercial needs, if any.

Table of Contents

●

Our third-party manufacturers might be unable to formulate and manufacture our product candidates in the volume and with the quality required to meet our clinical needs and commercial needs, if any.

●

Our contract manufacturers may not perform as agreed or may not remain in the contract manufacturing business for the time required to supply our clinical trials or to successfully produce, store and distribute our product candidates.

●

Drug manufacturers are subject to ongoing periodic unannounced inspection by the FDA, and corresponding state agencies to ensure compliance with cGMPs and other government regulations and corresponding foreign standards. We do not have control over third-party manufacturers’ compliance with these regulations and standards.

●

If any third-party manufacturer makes improvements in the manufacturing process for our products, we may not own, or may have to share, the intellectual property rights to the innovation.

●

Our contract manufacturers have in the past and may in the future encounter difficulties in achieving quality control and quality assurance and may experience shortages in qualified personnel. Our contract manufacturers are subject to inspections by the FDA and comparable agencies in other jurisdictions to assess compliance with applicable regulatory requirements. Any failure to follow cGMP or other regulatory requirements or delay, interruption or other issues that arise in the manufacture, packaging, or storage of our products as a result of a failure of the facilities or operations of third parties to comply with regulatory requirements or pass any regulatory authority inspection could significantly impair our ability to develop and commercialize our products, including leading to significant delays in the availability of products for our clinical studies or the termination or hold on a clinical study, or the delay or prevention of a filing or approval of marketing applications for our product candidates. Significant noncompliance could also result in the imposition of sanctions, including fines, injunctions, civil penalties, failure of regulatory authorities to grant marketing approvals for our product candidates, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of products, operating restrictions and criminal prosecutions, any of which could damage our reputation. If we or our contract manufacturers are not able to maintain regulatory compliance, we may not be permitted to market our products and/or may be subject to product recalls, seizures, injunctions, or criminal prosecution.

●

If we establish in-house development and manufacturing capabilities, there are a number of risks that could impact our financial condition, operating results and cash flows due to disruption of operations at the location or facility which may impede our ability to deliver assays or manufacture our products.

Each of these risks could delay our clinical trials, the approval, if any, of our product candidates by the FDA or the commercialization of our product candidates or could also result in higher costs or deprive us of potential product revenues.

We rely on third parties to conduct, supervise and monitor our clinical trials, and if those third parties perform in an unsatisfactory manner, it may harm our business.

We rely on CROs and clinical trial sites to ensure the proper and timely conduct of our clinical trials, and we expect to have limited influence over their actual performance.

We also rely upon CROs to monitor and manage data for our clinical programs, as well as the execution of future nonclinical studies. We expect to control only certain aspects of our CROs’ activities. Nevertheless, we will be responsible for ensuring that each of our studies is conducted in accordance with the applicable protocol, legal, regulatory and scientific standards and our reliance on the CROs does not relieve us of our regulatory responsibilities.

We and our CROs will be required to comply with the Good Laboratory Practices and GCPs, which are regulations and guidelines enforced by the FDA and are also required by the Competent Authorities of the Member States of the European Economic Area and comparable foreign regulatory authorities in the form of International Conference on Harmonization of Technical Requirements for Pharmaceuticals for Human Use guidelines for any of our product candidates that are in

Table of Contents

preclinical and clinical development. The Regulatory authorities enforce GCPs through periodic inspections of trial sponsors, principal investigators and clinical trial sites. If we or our CROs fail to comply with GCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. Accordingly, if our CROs fail to comply with these regulations or fail to recruit a sufficient number of subjects, we may be required to repeat clinical trials, which would delay the regulatory approval process.

Our CROs will not be our employees, and we will not control whether or not they devote sufficient time and resources to our future clinical and nonclinical programs. These CROs may also have relationships with other commercial entities, including our competitors, for whom they may also be conducting clinical trials, or other drug development activities which could harm our competitive position. We face the risk of potential unauthorized disclosure or misappropriation of our intellectual property by CROs, which may reduce our trade secret protection and allow our potential competitors to access and exploit our proprietary technology. If our CROs do not successfully carry out their contractual duties or obligations, fail to meet expected deadlines, or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols or regulatory requirements or for any other reasons, our clinical trials may be extended, delayed or terminated, and we may not be able to obtain regulatory approval for, or successfully commercialize any product candidate that we develop. As a result, our financial results and the commercial prospects for any product candidate that it develops would be harmed, its costs could increase, and our ability to generate revenues could be delayed.

If our relationship with these CROs terminate, we may not be able to enter into arrangements with alternative CROs or do so on commercially reasonable terms. Switching or adding additional CROs involves substantial cost and requires management time and focus. In addition, there is a natural transition period when a new CRO commences work. As a result, delays occur, which can materially impact our ability to meet our desired clinical development timelines. Though we intend to carefully manage our relationships with our CROs, there can be no assurance that it will not encounter challenges or delays in the future or that these delays or challenges will not have an adverse impact on our business, financial condition and prospects.

For our product candidates, we rely upon third parties to manufacture and supply our drug substance. Any problems experienced by either our third-party manufacturers or their vendors could result in a delay or interruption in the supply of our product candidate to us until the third-party manufacturer or its vendor cures the problem or until we locate and qualify an alternative source of manufacturing and supply.

For our product candidates, we currently rely on third-party manufacturers to purchase from their third-party vendors the materials necessary to produce our product candidates and manufacture our product candidates for our clinical studies. We currently depend on third-party suppliers for key materials and services used in its research and development, as well as manufacturing processes, and are subject to certain risks related to the loss of these third-party suppliers or their inability to supply us with adequate materials and services. We do not control the manufacturing processes of the contract development and manufacturing organizations, or CDMOs, with whom it contracts and is dependent on these third parties for the production of its therapeutic candidates in accordance with relevant regulations (such as current Good Manufacturing Practices, or cGMP, which includes, among other things, quality control, quality assurance and the maintenance of records and documentation.

To succeed, clinical trials require adequate supplies of study material, which may be difficult or uneconomical to procure or manufacture and there can be no assurance that we will successfully procure such study material or even if procured, that we can do so in quantities and in a timely manner to allow our clinical trials to proceed as planned. We and our suppliers and vendors may not be able to (i) produce our study material to appropriate standards for use in clinical studies, (ii) perform under any definitive manufacturing, supply or service agreements with us, or (iii) remain in business for a sufficient time to successfully produce and market our product candidates. If we do not maintain important manufacturing and service relationships, we may fail to find a replacement supplier or required vendor or manufacturer which could delay or impair our ability to obtain regulatory approval for our products and substantially increase our costs or deplete profit margins, if any. Although we believe additional manufacturers and vendors are available, if any of our manufacturers or vendors were to limit or terminate production or otherwise fail to meet the quality or delivery requirements needed to satisfy the supply commitments, the process of locating and qualifying alternate sources could require up to several months,

Table of Contents

during which time our production could be delayed. Any such curtailment in the availability of products could have a material adverse effect on our business, financial position and results of operations. In addition, because regulatory authorities must generally approve raw material sources for pharmaceutical products, changes in raw material suppliers may result in production delays or higher raw material costs. Although we do believe that replacement manufacturers and vendors are available, we may not be able to enter into agreements with them on terms and conditions favorable to us and there could be a substantial delay before a new facility could be qualified and registered with the FDA and foreign regulatory authorities. If we are unable to establish in-house development and manufacturing capabilities, we may not be able to reduce our dependency on third-party manufacturers.

For our clinical trial of HS-110, we are administering our product candidates, in combination with other immunotherapy agents. Any problems obtaining the other immunotherapy agents could result in a delay or interruption in our clinical trials.

For our clinical trials of HS-110, we administer our product candidate in combination with another immunotherapy agent, nivolumab or pembrolizumab. Therefore, our success will be dependent upon the continued use of these other immunotherapy agents. We expect that our other product candidates will also be administered in combination with immunotherapy agents owned by third parties. If any of the immunotherapy agents that are used in our clinical trials are unavailable while the trials are continuing, our timeliness and commercialization costs could be impacted. In addition, if any of these other immunotherapy agents are determined to have safety of efficacy problems, our clinical trials and commercialization efforts would be adversely affected.

Adverse effects resulting from other immunotherapy drugs or therapies could also negatively affect the perceptions by members of the health care community, including physicians, about the safety and effectiveness of our product candidates.

There are many other companies that have developed or are currently trying to develop immunology vaccines for the treatment of cancer. If adverse effects were to result from any immunotherapy drugs or therapies being developed, manufactured and marketed by others it could be attributed to our products or immunotherapy protocols as a whole. In fact, in the past biologics have been associated with certain safety risks and other companies developing biologics have had patients in trials suffer from serious adverse events, including death. Any such attribution could negatively affect the perceptions by members of the health care community, including physicians, about the safety and effectiveness of our product candidates and the future of immunotherapy for the treatment of cancer. Our industry is susceptible to rapid technological changes and there can be no assurance that we will be able to match any new technological challenges presented by the adverse effects resulting from immunotherapy drugs or therapies developed, manufactured or marketed by others.

Even if we are able to obtain regulatory approval for our product candidates, we will continue to be subject to ongoing and extensive regulatory requirements, and our failure, or the failure of our contract manufacturers, to comply with these requirements could substantially harm our business.

If the FDA approves any of our product candidates, the labeling, manufacturing, packaging, adverse event reporting, storage, advertising, promotion and record keeping for our products will be subject to ongoing FDA requirements and continued regulatory oversight and review. We may also be subject to additional FDA post-marketing obligations. If we are not able to maintain regulatory compliance, we may not be permitted to market our product candidates and/or may be subject to product recalls or seizures. The subsequent discovery of previously unknown problems with any marketed product, including AEs of unanticipated severity or frequency, may result in restrictions on the marketing of the product, and could include withdrawal of the product from the market.

We have no experience selling, marketing or distributing products, and have no internal capability to do so.

We currently have no sales, marketing or distribution capabilities. We do not anticipate having the resources in the foreseeable future to allocate to the sales and marketing of our proposed products, if approved. Our future success depends, in part, on our ability to enter into and maintain collaborative relationships for such capabilities, the collaborator’s strategic interest in the products under development and such collaborator’s ability to successfully market and sell any such

Table of Contents

products. We intend to pursue collaborative arrangements regarding the sales and marketing of our products, however, there can be no assurance that we will be able to establish or maintain such collaborative arrangements, or if able to do so, that our collaborators will have effective sales forces. To the extent that we decide not to, or are unable to, enter into collaborative arrangements with respect to the sales and marketing of our proposed products, significant capital expenditures, management resources and time will be required to establish and develop an in-house marketing and sales force with technical expertise. There can also be no assurance that we will be able to establish or maintain relationships with third party collaborators or develop in-house sales and distribution capabilities. To the extent that we depend on third parties for marketing and distribution, any revenues we receive will depend upon the efforts of such third parties, and there can be no assurance that such efforts will be successful. In addition, there can also be no assurance that we will be able to successfully market and sell our products in the United States or overseas on our own.

We may not be successful in establishing and maintaining strategic partnerships, which could adversely affect our ability to develop and commercialize products.

We may seek to enter into strategic partnerships in the future, including alliances with other biotechnology or pharmaceutical companies, to enhance and accelerate the development and commercialization of our products. We face significant competition in seeking appropriate strategic partners and the negotiation process is time-consuming and complex. Moreover, we may not be successful in our efforts to establish a strategic partnership or other alternative arrangements for any future product candidates and programs because our research and development pipeline may be insufficient, our product candidates and programs may be deemed to be at too early of a stage of development for collaborative effort and/or third parties may not view our product candidates and programs as having the requisite potential to demonstrate safety and efficacy or return on investment. Even if we are successful in our efforts to establish strategic partnerships, the terms that we agree upon may not be favorable to us and we may not be able to maintain such strategic partnerships if, for example, development or approval of a product candidate is delayed or sales of an approved product are disappointing.

If we ultimately determine that entering into strategic partnerships is in our best interest, but either fail to enter into, are delayed in entering into or fail to maintain such strategic partnerships:

●

the development of certain of our current or future product candidates may be terminated or delayed;

●

our cash expenditures related to development of certain of our current or future product candidates may increase significantly and we may need to seek additional financing;

●

we may be required to hire additional employees or otherwise develop expertise, such as sales and marketing expertise, for which we have not budgeted;

●

we will bear all of the risk related to the development of any such product candidates; and

●

the competitiveness of any product candidate that is commercialized could be reduced.

To the extent we elect to enter into licensing or collaboration agreements to partner our product candidates, our dependence on such relationships may adversely affect our business.

Our commercialization strategy for certain of our product candidates may depend on our ability to enter into agreements with collaborators to obtain assistance and funding for the development and potential commercialization of these product candidates. Supporting diligence activities conducted by potential collaborators and negotiating the financial and other terms of a collaboration agreement are long and complex processes with uncertain results. Even if we are successful in entering into one or more collaboration agreements, collaborations may involve greater uncertainty for us, as we have less control over certain aspects of our collaborative programs than we do over our proprietary development and commercialization programs. We may determine that continuing collaboration under the terms provided is not in our best interest, and we may terminate the collaboration. Our collaborators could delay or terminate their agreements, and our product candidates subject to collaborative arrangements may never be successfully developed or commercialized.

Further, our future collaborators may develop alternative products or pursue alternative technologies either on their own or in collaboration with others, including our competitors, and the priorities or focus of our collaborators may shift such that our programs receive less attention or fewer resources than we would like, or they may be terminated altogether. Any such actions by our collaborators may adversely affect our business prospects and ability to earn revenues. In addition, we

Table of Contents

could have disputes with our future collaborators, such as the interpretation of terms in our agreements. Any such disagreements could lead to delays in the development or commercialization of any potential products or could result in time-consuming and expensive litigation or arbitration, which may not be resolved in our favor.

Our ability to generate product revenues will be diminished if our therapies sell for inadequate prices or patients are unable to obtain adequate levels of reimbursement.

Our ability to commercialize our therapies, alone or with collaborators, will depend in part on the extent to which reimbursement will be available from:

●

government and health administration authorities;

●

private health maintenance organizations and health insurers; and

●

other healthcare payers.

Significant uncertainty exists as to the reimbursement status of newly approved healthcare products. Healthcare payers, including Medicare, are challenging the prices charged for medical products and services. Cost control initiatives could decrease the price that we would receive for any products in the future, which would limit our revenue and profitability. Government and other healthcare payers increasingly attempt to contain healthcare costs by limiting both coverage and the level of reimbursement for drugs and therapeutics. We might need to conduct post-marketing studies in order to demonstrate the cost-effectiveness of any future products to such payers’ satisfaction. Such studies might require us to commit a significant amount of management time and financial and other resources. Our future products might not ultimately be considered cost-effective. Even if one of our product candidates is approved by the FDA, insurance coverage may not be available, and reimbursement levels may be inadequate, to cover such therapies. If government and other healthcare payers do not provide adequate coverage and reimbursement levels for one of our products, once approved, market acceptance of such product could be reduced.

Legislative and regulatory changes affecting the health care industry could adversely affect our business.

Political, economic and regulatory influences are subjecting the health care industry to potential fundamental changes that could substantially affect our results of operations. In many countries, the government controls the pricing and profitability of prescription pharmaceuticals. In the United States, we expect that there will continue to be federal and state proposals to implement similar governmental controls. In addition, recent changes in the Medicare program and increasing emphasis on managed care in the United States will continue to put pressure on pharmaceutical product pricing. It is uncertain whether or when any legislative proposals will be adopted or what actions federal, state, or private payers for health care treatment and services may take in response to any health care reform proposal or legislation. We cannot predict the effect health care reforms may have on our business and we can offer no assurances that any of these reforms will not have a material adverse effect on our business. These actual and potential changes are causing the marketplace to put increased emphasis on the delivery of more cost-effective treatments. In addition, uncertainly remains regarding proposed significant reforms to the U.S. health care system.

In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could, among other things, prevent or delay marketing approval of our clinical product candidate, restrict or regulate post-approval activities and affect our ability to profitably sell any product candidate for which we obtain marketing approval. Changes in regulations, statutes or the interpretation of existing regulations could impact our business in the future by requiring, for example: (i) changes to our manufacturing arrangements, (ii) additions or modifications to product labeling, (iii) the recall or discontinuation of our products or (iv) additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect our business, financial condition and results of operations.

Among policy makers in the United States and elsewhere, 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. In March 2010, The Patient Protection and Affordable Care Act (ACA), was passed, which substantially changed the way healthcare is financed by both the government and private insurers, and significantly impacts

Table of Contents

the U.S. pharmaceutical industry. The ACA, among other things, subjects biological products to potential competition by lower-cost biosimilars, addresses a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected, increases the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and extends the rebate program to individuals enrolled in Medicaid managed care organizations, establishes annual fees and taxes on manufacturers of certain branded prescription drugs, and creates a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D.

Some of the provisions of the ACA have yet to be fully implemented, while certain provisions have been subject to judicial and Congressional challenges. It is unclear how these challenges and other efforts to replace the ACA will impact our business in the futures.

Moreover, the Drug Supply Chain Security Act imposes obligations on manufacturers of prescription drugs in finished dosage forms. We have not yet adopted the significant measures that will be required to comply with this law. We are not sure whether additional legislative changes will be enacted, or whether the current regulations, guidance or interpretations will be changed, or what the impact of such changes on our business, if any, may be.

There have been, and likely will continue to be, legislative and regulatory proposals at the foreign, federal and state levels directed at broadening the availability of healthcare and containing or lowering the cost of healthcare. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our products. Such reforms could have an adverse effect on anticipated revenue from product candidates that we may successfully develop and for which we may obtain regulatory approval and may affect our overall financial condition and ability to develop product candidates.

We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products, which could result in reduced demand for our clinical product candidate or additional pricing pressures. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors.

We may be exposed to liability claims associated with the use of biological and hazardous materials and chemicals.

Our research and development activities may involve the controlled use of biological and hazardous materials and chemicals. Although we believe that our safety procedures for using, storing, handling and disposing of these materials comply with federal, state and local laws and regulations, we cannot completely eliminate the risk of accidental injury or contamination from these materials. We currently operate one laboratory in North Carolina, one laboratory in New Jersey and Pelican operates a laboratory in Texas. In our laboratory in Texas we perform contract services for third parties that could involve the use of biological and hazardous materials and chemicals. In the event of such an accident, we could be held liable for any resulting damages and any liability could materially adversely affect our business, financial condition and results of operations. In addition, the federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of hazardous or radioactive materials and waste products may require us to incur substantial compliance costs that could materially adversely affect our business, financial condition and results of operations.

We may incur substantial liabilities and may be required to limit commercialization of our products in response to product liability lawsuits.

The testing and marketing of drug and biological product candidates entail an inherent risk of product liability. Product liability claims might be brought against us by consumers, health care providers or others selling or otherwise coming into contact with our products. We currently operate one laboratory in North Carolina, one laboratory in New Jersey and Pelican operates a laboratory in Texas. In our laboratory in Texas we perform contract services for third parties. We could incur liability in the performance of these services, including liability for damage to materials supplied to us. Clinical trial liability claims may be filed against us for damages suffered by clinical trial subjects or their families. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit

Table of Contents

commercialization of our products which could impact our ability to continue as a going concern. Our inability to obtain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of pharmaceutical products we develop, alone or with collaborators. In addition, regardless of merit or eventual outcome, product liability claims may result in:

●

decreased demand for any approved product candidates;

●

impairment of our business reputation;

●

withdrawal of clinical trial participants;

●

costs of related litigation;

●

distraction of management’s attention;

●

substantial monetary awards to patients or other claimants;

●

loss of revenues; and

●

the inability to successfully commercialize any approved drug candidates.

International expansion of our business exposes us to business, regulatory, political, operational, financial and economic risks associated with doing business outside of the United States.

Our business strategy incorporates international expansion, including establishing and maintaining clinician marketing and education capabilities outside of the United States and expanding our relationships with distributors and manufacturers. Doing business internationally involves a number of risks, including:

●

multiple, conflicting and changing laws and regulations such as tax laws, export and import restrictions, employment laws, regulatory requirements and other governmental approvals, permits and licenses;

●

failure by us or our distributors to obtain regulatory approvals for the sale or use of our product candidates in various countries;

●

difficulties in managing foreign operations;

●

complexities associated with managing multiple payor-reimbursement regimes or self-pay systems;

●

limits on our ability to penetrate international markets if our product candidates cannot be processed by a manufacturer appropriately qualified in such markets;

●

financial risks, such as longer payment cycles, difficulty enforcing contracts and collecting accounts receivable and exposure to foreign currency exchange rate fluctuations;

●

reduced protection for intellectual property rights;

●

natural disasters, political and economic instability, including wars, terrorism and political unrest, outbreak of disease, boycotts, curtailment of trade and other business restrictions; and

●

failure to comply with the Foreign Corrupt Practices Act, including its books and records provisions and its anti-bribery provisions, by maintaining accurate information and control over sales and distributors’ activities.

Any of these risks, if encountered, could significantly harm our future international expansion and operations and, consequently, have a material adverse effect on our financial condition, results of operations and cash flows.

We may acquire other businesses or form joint ventures or make investments in other companies or technologies or new lines of business that could harm our operating results, dilute our stockholders’ ownership, increase our debt or cause us to incur significant expense.

As part of our business strategy, we may pursue acquisitions of businesses and assets, such as we did with the Pelican. We may also make investments in other companies of technologies, new lines of business, or expansion of research bioanalytical development and manufacturing capacities. We also may pursue strategic alliances and joint ventures that leverage our core technology and industry experience to expand our offerings or distribution. Other than our acquisition of the equity of Pelican in 2017, we have no experience with acquiring other companies and limited experience with forming strategic alliances and joint ventures. We may not be able to find suitable partners or acquisition candidates, and we may not be able to complete such transactions on favorable terms, if at all. If we make any acquisitions, we may not be able to integrate these acquisitions successfully into our existing business, and we could assume unknown or contingent

Table of Contents

liabilities. Any future acquisitions or investments in other companies or technologies or new lines of business also could result in significant write-offs or the incurrence of debt and contingent liabilities, any of which could have a material adverse effect on our financial condition, results of operations and cash flows. Integration of an acquired company also may disrupt ongoing operations and require management resources that would otherwise focus on developing our existing business. We may experience losses related to investments in other companies, which could have a material negative effect on our results of operations. We may not identify or complete these transactions in a timely manner, on a cost-effective basis, or at all, and we may not realize the anticipated benefits of any acquisition, technology license, strategic alliance or joint venture.

To finance any acquisitions or joint ventures, we may choose to issue shares of our common stock as consideration, which would dilute the ownership of our stockholders. If the price of our common stock is low or volatile, we may not be able to acquire other companies or fund a joint venture project using our stock as consideration. Alternatively, it may be necessary for us to raise additional funds for acquisitions through public or private financings. Additional funds may not be available on terms that are favorable to us, or at all.

Uncertainty regarding health care reform and declining general economic or business conditions may have a negative impact on our business.

Continuing concerns over U.S. health care reform legislation and energy costs, geopolitical issues, the availability and cost of credit and government stimulus programs in the United States and other countries have contributed to increased volatility and diminished expectations for the global economy. If the economic climate does not improve or continues to be uncertain, our business, as well as the financial condition of our suppliers and our third-party payors, could be adversely affected, resulting in a negative impact on our business, financial condition and results of operations.

Government actions or interventions may curtail our ability to develop a successful COVID-19 vaccine, which may be more likely during a global health crisis such as COVID-19.

Given the significant global impact of the COVID-19 pandemic, it is possible that one or more government entities may take actions that directly or indirectly have the effect of diminishing some of our rights or opportunities with respect to our COVID-19 vaccine product candidate, limiting our economic prospects. In the U.S., the Defense Production Act of 1950, as amended (the “Defense Production Act”), gives the U.S. government rights and authorities that may directly or indirectly diminish our own rights or economic opportunities with respect to our COVID-19 vaccine. Our current and potential third-party service providers may be impacted by government entities potentially invoking the Defense Production Act or other potential restrictions to all or a portion of services they might otherwise offer.

Reliance on government funding for Pelican’s programs may impose requirements that limit Pelican’s ability to take certain actions, and subject it to potential financial penalties, which could materially and adversely affect its business, financial condition and results of operations.

A significant portion of Pelican’s funding has been through a grant it received from the CPRIT Grant. The CPRIT Grant includes provisions that reflect the government’s substantial rights and remedies, many of which are not typically found in commercial contracts, including powers of the government to potentially require repayment of all or a portion of the grant award proceeds, in certain cases with interest, in the event Pelican violates certain covenants pertaining to various matters that include any potential relocation outside of the State of Texas. After the CPRIT Grant ends, Pelican is not permitted to retain any unused grant award proceeds without CPRIT’s approval, but Pelican’s royalty and other obligations, including its obligation to repay the disbursed grant proceeds under certain circumstances, , to maintain certain records and documentation, to notify CPRIT of certain unexpected adverse events and our obligation to use reasonable efforts to ensure that any new or expanded preclinical testing, clinical trials, commercialization or manufacturing related to any aspect to our CPRIT project take place in Texas, survive the termination of the agreement.

Pelican’s award from CPRIT requires it to pay CPRIT a portion of its revenues from sales of certain products by it, or received from its licensees or sublicensees, at tiered percentages of revenue in the low- to mid-single digits until the aggregate amount of such payments equals 400% of the grant award proceeds, and thereafter at a rate of less than one percent for as long as Pelican maintains government exclusivity, subject to Pelican’s right, under certain circumstances, to

Table of Contents

make a one-time payment in a specified amount to CPRIT to terminate such payment obligations. In addition, the grant contract also contains a provision that provides for repayment to CPRIT of some amount not to exceed the full amount of the grant proceeds under certain specified circumstances involving relocation of Pelican’s principal place of business outside Texas.

The CPRIT Grant requires Pelican, as a Texas-based company, to meet certain criteria, including among other things, that Pelican maintain its headquarters in Texas and use certain vendors, consultants and employees that are located in Texas. If Pelican fails to maintain compliance with any such requirements that may apply to it now or in the future, it may be subject to potential liability and to termination of its contracts, including potentially the CPRIT Grant.

If Pelican is unable to hire additional qualified personnel, its ability to utilize the CPRIT Grant will be forfeited.

In order to access the CPRIT Grant a majority of Pelican’s employees must reside in Texas as well as its Chief Executive Officer. Pelican has identified qualified individuals and will have to negotiate agreements with each identified individual and will also need to hire such additional qualified personnel with expertise in preclinical testing, clinical research and testing, government regulation, formulation and manufacturing, sales and marketing and accounting and financing. Pelican will compete for qualified individuals with numerous biopharmaceutical companies, universities and other research institutions. Competition for such individuals is intense, and there can be no assurance that the search for such personnel will be successful. Attracting and retaining qualified personnel will be critical to Pelican’s access to the CPRIT Grant.

We rely extensively on our information technology systems and are vulnerable to damage and interruption.

We rely on our information technology systems and infrastructure to process transactions, summarize results and manage our business, including maintaining client and supplier information. Additionally, we utilize third parties, including cloud providers, to store, transfer and process data. Our information technology systems, as well as the systems of our suppliers and other partners, whose systems we do not control, are vulnerable to outages and an increasing risk of continually evolving deliberate intrusions to gain access to company sensitive information. Likewise, data security incidents and breaches by employees and others with or without permitted access to our systems pose a risk that sensitive data may be exposed to unauthorized persons or to the public. A cyber-attack or other significant disruption involving our information technology systems, or those of our vendors, suppliers and other partners, could also result in disruptions in critical systems, corruption or loss of data and theft of data, funds or intellectual property. We may be unable to prevent outages or security breaches in our systems. We remain potentially vulnerable to additional known or yet unknown threats as, in some instances, we, our suppliers and our other partners may be unaware of an incident or its magnitude and effects. We also face the risk that we expose our vendors or partners to cybersecurity attacks. Any or all of the foregoing could adversely affect our results of operations and our business reputation.

Any failure to maintain the security of information relating to our customers, employees and suppliers, whether as a result of cybersecurity attacks or otherwise, could expose us to litigation, government enforcement actions and costly response measures, and could disrupt our operations and harm our reputation We are a smaller reporting company, and we cannot be certain if the reduced reporting requirements applicable to smaller reporting companies will make our common stock less attractive to investors.

In connection with the sales and marketing of our products and services, we may from time to time transmit confidential information. We also have access to, collect or maintain private or confidential information regarding our clinical trials and the patients enrolled therein, employees, and suppliers, as well as our business. Cyberattacks are rapidly evolving and becoming increasingly sophisticated. It is possible that computer hackers and others might compromise our security measures, or security measures of those parties that we do business with now or in the future and obtain the personal information of patients in our clinical trials, vendors, employees and suppliers or our business information. A security breach of any kind, including physical or electronic break-ins, computer viruses and attacks by hackers, employees or others, could expose us to risks of data loss, litigation, government enforcement actions, regulatory penalties and costly response measures, and could seriously disrupt our operations. Any resulting negative publicity could significantly harm our reputation, which could cause us to lose market share and have an adverse effect on our results of operations.

Risks Related to Intellectual Property

We have limited protection for our intellectual property, which could impact our competitive position.

We intend to rely on a combination of common law copyright, patent, trademark, and trade secret laws and measures to protect our proprietary information. We have obtained exclusive rights to license the technology for which patent protection has been obtained; however, certain patents expired in 2019 and such protection does not prevent unauthorized use of such technology. In addition, our license for certain cell lines are subject to non-exclusive licenses and do not have patent protection. Trademark and copyright protections may be limited, and enforcement could be too costly to be effective. It may also be possible for unauthorized third parties to copy aspects of, or otherwise obtain and use, our proprietary information without authorization, including, but not limited to, product design, software, customer and prospective customer lists, trade secrets, copyrights, patents and other proprietary rights and materials. Other parties can use and register confusingly similar business, product and service names, as well as domain names, which could divert customers, resulting in a material adverse effect on our business, operating results and financial condition.

Intellectual property rights may also be unavailable or limited in some foreign countries, which could make it easier for competitors to capture market share. Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets and other intellectual property protection, particularly those relating to biotechnology products, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights generally. Many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. As a result, in response to the COVID-19 pandemic, it is possible that certain countries may take steps to facilitate compulsory licenses that permit the distribution of a COVID-19 vaccine in those countries. In addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of the relevant patent rights. If we or any of our licensors is forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position may be impaired, and our business, financial condition, results of operations, and prospects may be adversely affected.

If we fail to successfully enforce our intellectual property rights, our competitive position could suffer, which could harm our operating results. Competitors may challenge the validity or scope of our patents or future patents we may obtain. In addition, our licensed patents may not provide us with a meaningful competitive advantage. We may be required to spend significant resources to monitor and police our licensed intellectual property rights. We may not be able to detect infringement and our competitive position may be harmed. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful. In addition, competitors may design around our technology or develop competing technologies.

The technology we license, our products or our development efforts may be found to infringe upon third-party intellectual property rights.

Third parties may in the future assert claims or initiate litigation related to their patent, copyright, trademark and other intellectual property rights in technology that is important to us. The asserted claims and/or litigation could include claims against us, our licensors or our suppliers alleging infringement of intellectual property rights with respect to our products or components of those products. Regardless of the merit of the claims, they could be time consuming, result in costly litigation and diversion of technical and management personnel, or require us to develop a non-infringing technology or enter into license agreements. We have not undertaken an exhaustive search to discover any third party intellectual patent rights, which might be infringed by commercialization of the product candidates described herein. Although we are not currently aware of any such third-party intellectual patent rights, it is possible that such rights currently exist or might be obtained in the future. In the event that a third party controls such rights and we are unable to obtain a license to such rights on commercially reasonable terms, we may not be able to sell or continue to develop our products, and may be liable for damages for such infringement. We cannot assure you that licenses will be available on acceptable terms, if at all.

Table of Contents

Furthermore, because of the potential for significant damage awards, which are not necessarily predictable, it is not unusual to find even arguably unmeritorious claims resulting in large settlements. If any infringement or other intellectual property claim made against us by any third party is successful, or if we fail to develop non-infringing technology or license the proprietary rights on commercially reasonable terms and conditions, our business, operating results and financial condition could be materially adversely affected.

If our products, methods, processes and other technologies infringe the proprietary rights of other parties, we could incur substantial costs and we may have to:

●

obtain licenses, which may not be available on commercially reasonable terms, if at all;

●

abandon an infringing drug or therapy candidate;

●

redesign our products or processes to avoid infringement;

●

stop using the subject matter claimed in the patents held by others;

●

pay damages; or

●

defend litigation or administrative proceedings which may be costly whether we win or lose, and which could result in a substantial diversion of our financial and management resources.

We rely on licenses to use various technologies that are material to our business and if the agreements were to be terminated or if other rights that may be necessary or we deem advisable for commercializing our intended products cannot be obtained, it would halt our ability to market our products and technology, as well as have an immediate material adverse effect on our business, operating results and financial condition.

We have licensing agreements with certain universities granting us the right to use certain critical intellectual property. The terms of the licensing agreements continue until the end of the life of the last patent to expire. If we breach the terms of these licensing agreements, including any failure to make minimum royalty payments required thereunder or failure to reach certain developmental milestones, using best efforts to introduce a licensed product in certain territories by certain dates, the licensor has the right to terminate the license. If we were to lose or otherwise be unable to maintain these licenses on acceptable terms, or find that it is necessary or appropriate to secure new licenses from other third parties, it would halt our ability to market our products and technology, which would have an immediate material adverse effect on our business, operating results and financial condition.

We may be unable to generate sufficient revenues to meet the minimum annual payments or developmental milestones required under our license agreements.

For the years ended December 31, 2021, 2022, and 2023 our minimum annual payment obligations under our licensing agreements required to be paid by us or our subsidiaries with the passage of time, are approximately $0.2 million, $0.8 million and $0.07 million, respectively. No assurance can be given that we will generate sufficient revenue or raise additional financing to make these minimum royalty payments or milestone payments owed to the Pelican Stockholders pursuant to the terms of the stock purchase agreement that we entered into with Pelican and certain stockholders of Pelican in March 2017. The license agreements also provide for certain developmental milestones, as does the purchase agreement that we entered into with Pelican and certain stockholders of Pelican in March 2017, including future payments to Pelican based on the achievement of certain milestones. No assurance can be given that we will meet all of the required developmental milestones or have sufficient funds to make required payments under the purchase agreement. Any failure to make the payments or reach the milestones required by the license agreements would permit the licensor to terminate the license and any failure to make payments under the purchase agreement would constitute a default under the purchase agreement. If we were to lose or otherwise be unable to maintain these licenses, it would halt our ability to market our products and technology, which would have an immediate material adverse effect on our business, operating results and financial condition.

The U.S. government may have “march-in rights” to certain of our intellectual property.

Because federal grant monies were used in support of the research and development activities that resulted in certain of our issued pending U.S. patent applications, the federal government retains what are referred to as “march-in rights” to patents that are granted on these applications.

In particular, the National Institutes of Health, which administered grant monies to the primary inventor of the technology we license, technically retain the right to require us, under certain specific circumstances, to grant the U.S. government either a nonexclusive, partially exclusive or exclusive license to the patented invention in any field of use, upon terms that are reasonable for a particular situation. Circumstances that trigger march-in rights include, for example, failure to take, within a reasonable time, effective steps to achieve practical application of the invention in a field of use, failure to satisfy the health and safety needs of the public and failure to meet requirements of public use specified by federal regulations. The National Institutes of Health can elect to exercise these march-in rights on their own initiative or at the request of a third-party.

General Risk Factors

We may not successfully effect our intended expansion, which would harm our business prospects.

Our success will depend upon the expansion of our operations and the effective management of our growth, which will place a significant strain on our management, and on our administrative, operational and financial resources. To manage this growth, we must expand our facilities; augment our operational, financial and management systems; and hire and train additional qualified personnel. If we are unable to manage our growth effectively, our business would be harmed.

We rely on key executive officers and scientific and medical advisors, and their knowledge of our business and technical expertise would be difficult to replace.

We are highly dependent on our principal scientific, regulatory and medical advisors and our chief executive officer. Other than a $2.0 million insurance policy we hold on the life of Jeffrey Wolf, we do not have “key person” life insurance policies for any of our officers or advisors. The loss of the technical knowledge, management and industry expertise of any of our key personnel could result in delays in product development, loss of customers and sales and diversion of management resources, which could adversely affect our operating results.

If we are unable to hire additional qualified personnel, our ability to grow our business may be harmed.

We will need to hire additional qualified personnel with expertise in preclinical and clinical research, government regulation, formulation and manufacturing, sales and marketing and accounting and financing. Over the next 12 months, we expect to hire additional new employees both in North Carolina and for Pelican in Texas. In fact, due to the CPRIT Grant and certain other funding we have received, we are required to hire employees located in Texas. We compete for qualified individuals with numerous biopharmaceutical companies, universities and other research institutions. Competition for such individuals is intense, and we cannot be certain that our search for such personnel will be successful especially in light of the CPRIT Grant requirements, including the requirement that Pelican maintain its headquarters in Texas and use certain vendors, consultants and employees located in Texas. Attracting and retaining qualified personnel will be critical to our success.

We are a smaller reporting company, and we cannot be certain if the reduced reporting requirements applicable to smaller reporting companies will make our common stock less attractive to investors.

We are a smaller reporting company under Rule 12b-2 of the Exchange Act. For as long as we continue to be a smaller reporting company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not smaller reporting companies, including reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. However, our status as a smaller reporting company will not exempt us from the requirement to provide the annual attestation report from our independent registered public accounting firm regarding the effectiveness of our internal control over financial reporting. We cannot predict if investors will find our common stock less attractive because we may rely on smaller reporting company exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock, and our stock price may be more volatile.

There can be no assurance that we will be able to comply with the applicable regulations in a timely manner, if at all.

Our failure to meet the continued listing requirements of The Nasdaq Capital Market could result in a de-listing of our common stock.

Our shares of common stock are currently listed on The Nasdaq Capital Market. If we fail to satisfy the continued listing requirements of The Nasdaq Capital Market, such as the corporate governance requirements, minimum bid price requirement or the minimum stockholder’s equity requirement, The Nasdaq Capital Market may take steps to de-list our common stock. Any de-listing would likely have a negative effect on the price of our common stock and would impair stockholders’ ability to sell or purchase their common stock when they wish to do so. In the past we have received notices from the Listing Qualifications Department of Nasdaq Stock Market LLC (“Nasdaq”) that we failed to comply with the stockholder’s equity requirements and the minimum closing bid requirements. On June 21, 2019, we received written notice from the Listing Qualifications Department of the Nasdaq Stock Market LLC notifying us that for the preceding 30 consecutive business days (May 9, 2019 through June 20, 2019), our common stock did not maintain a minimum closing bid price of $1.00 per share (“Minimum Bid Price Requirement”) as required by Nasdaq Listing Rule 5550(a)(2). On July 24, 2020, we received written notice from The Nasdaq Capital Market that from July 10, 2020 through July 23, 2020, the closing bid price of our common stock has been at $1.00 per share or greater and accordingly we had regained compliance with Nasdaq Listing Rule 5550(a)(2) and the matter was now closed. There can be no assurance given that we will be able to continue to satisfy our continued listing requirements and maintain the listing of our common stock on The Nasdaq Capital Market going forward.

The possible issuance of common stock subject to options, restricted stock units and warrants may dilute the interests of stockholders.

As of March 22, 2021, awards for 1,977,354 shares of common stock are outstanding under our equity compensation plans and 1,055,747 shares of common stock remain available for grants under the plans. In addition, as of March 22, 2021, we have warrants exercisable for 789,691 shares of our common stock to third parties in connection with our public offerings. To the extent that outstanding stock options and warrants are exercised, or additional securities are issued, dilution to the interests of our stockholders may occur. Moreover, the terms upon which we will be able to obtain additional equity capital may be adversely affected since the holders of the outstanding options can be expected to exercise them at a time when we would, in all likelihood, be able to obtain any needed capital on terms more favorable to us than those provided in such outstanding options.

We have additional securities available for issuance, which, if issued, could adversely affect the rights of the holders of our common stock.

Our certificate of incorporation authorizes the issuance of 250,000,000 shares of our common stock and 10,000,000 shares of preferred stock. In certain circumstances, the common stock and preferred stock, as well as the awards available for issuance under the incentive plans, can be issued by our board of directors, without stockholder approval. Any future issuances of such stock would further dilute the percentage ownership of us held by holders of preferred stock and common stock. Our board of directors is authorized to create and issue from time to time, only with stockholder approval, up to an aggregate of 10,000,000 shares of preferred stock of which 8,212,500 have been designated. The authority to designate preferred stock may be used to issue series of preferred stock, or rights to acquire preferred stock, that could dilute the interest of, or impair the voting power of, holders of the common stock or could also be used as a method of determining, delaying or preventing a change of control.

We have never paid dividends and have no plans to pay dividends in the future.

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 our preferred or common stock and we do not expect to pay cash dividends in the foreseeable future. We intend to retain future earnings, if any, to provide funds for operations of our business. Therefore, any return investors in our preferred or common stock may have will be in the form of appreciation, if any, in the market value of their shares of common stock.

Table of Contents

Certain provisions of the General Corporation Law of the State of Delaware, our bylaws and stockholder rights plan may have anti-takeover effects that may make an acquisition of our company by another company more difficult.

We are subject to the provisions of Section 203 of the General Corporation Law of the State of Delaware, which prohibits a Delaware corporation from engaging in any business combination, including mergers and asset sales, with an interested stockholder (generally, a 15% or greater stockholder) for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. The operation of Section 203 may have anti-takeover effects, which could delay, defer or prevent a takeover attempt that a holder of our common stock might consider in its best interest. Certain provisions of our bylaws including the ability of our board of directors to fill vacancies on our board of directors and advance notice requirements for stockholder proposals and nominations may prevent or frustrate attempts by our stockholders to replace or remove our management. In addition, the Rights issued pursuant to our stockholder rights plan that we implemented, if not redeemed or suspended, could result in the dilution of the stock ownership of a potential hostile acquirer, likely preventing acquisitions that have not been approved by our board of directors and therefore discouraging, delaying or preventing a change in control that stockholders may consider favorable.

Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware will be the exclusive forum for certain types of state actions that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.

Our amended and restated bylaws provide that, unless we consent to the selection of an alternative forum, the Court of Chancery of the State of Delaware is the exclusive forum for (i) any derivative action or proceeding brought on behalf of us, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, or other employees to us or our stockholders, (iii) any action arising pursuant to any provision of the DGCL or our certificate of incorporation or bylaws (as either may be amended from time to time), or (iv) any action asserting a claim governed by the internal affairs doctrine, except, in each case for claims arising under the Securities Act of 1933, as amended, the Exchange Act, or other federal securities laws for which there is exclusive federal or concurrent federal and state jurisdiction.

These exclusive-forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, employees, control persons, underwriters, or agents, which may discourage lawsuits against us and our directors, employees, control persons, underwriters, or agents. Additionally, a court could determine that the exclusive forum provision is unenforceable, and our stockholders will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder. If a court were to find these provisions of our amended and restated bylaws inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition, or results of operations.

Future sales of our common stock by our existing stockholders could cause our stock price to decline.

On March 22, 2021, we had 25,410,098 shares of our common stock outstanding, all of which are currently eligible for sale in the public market, subject, in certain circumstances to the volume, manner of sale and other limitations under Rule 144 promulgated under the Securities Act. It is conceivable that stockholders may wish to sell some or all of their shares. If our stockholders sell substantial amounts of our common stock in the public market at the same time, the market price of our common stock could decrease significantly due to an imbalance in the supply and demand of our common stock. Even if they do not actually sell the stock, the perception in the public market that our stockholders might sell significant shares of our common stock could also depress the market price of our common stock.

A decline in the price of shares of our common stock might impede our ability to raise capital through the issuance of additional shares of our common stock or other equity securities, and may cause stockholders to lose part or all of their investment in our shares of common stock.

Table of Contents

Our common stock has from time to time been “thinly-traded,” meaning that the number of persons interested in purchasing our common stock at or near ask prices at any given time may be relatively small or non-existent. This situation is attributable to a number of factors, including the fact that we are a small company that is relatively unknown to stock analysts, stock brokers, institutional investors and others in the investment community that generate or influence sales volume, and that even if we came to the attention of such persons, they tend to be risk-averse and would be reluctant to follow an unproven company such as ours or purchase or recommend the purchase of our shares until such time as we became more seasoned and viable. As a consequence, there may be periods of several days or more when trading activity in our shares is minimal or non-existent, as compared to a seasoned issuer that has a large and steady volume of trading activity that will generally support continuous sales without an adverse effect on share price. We cannot give stockholders any assurance that a broader or more active public trading market for our common shares will develop or be sustained, or that current trading levels will be sustained.

Holders of our warrants will have no rights as a common stockholder until they acquire our common stock.

Until warrant holders acquire shares of our common stock upon exercise of their warrants, the warrant holders will have no rights with respect to shares of our common stock issuable upon exercise of their warrants. Upon exercise of the warrants, the warrant holders will be entitled to exercise the rights of a common stockholder only as to matters for which the record date occurs after the exercise date.

Our previously issued warrants may not have any value.

Our previously issued warrants to purchase shares of our common stock may not have any value. For example, we previously issued warrants in a public offering that have an exercise price of $11.09 per share. In the event that our common stock price does not exceed the exercise price of our previously issued warrants during the period when the warrants are exercisable, the warrants may not have any value.

There is no established market for the warrants that we previously issued.

There is no established trading market for the warrants that we previously issued, including those issued in a public offering, and we do not expect a market to develop. In addition, we do not intend to apply for the listing of the warrants on any national securities exchange or other trading market. Without an active trading market, the liquidity of the warrants will be limited.

The shares of common stock offered under any at the market offering that we may engage in, and investors who buy shares at different times will likely pay different prices.

Investors who purchase shares that are sold under at-the-market-offerings at different times will likely pay different prices, and so 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 declines in the value of their shares as a result of share sales made at prices lower than the prices they paid.

Reports published by securities or industry analysts, including projections in those reports that exceed our actual results, could adversely affect our common stock price and trading volume.

Securities research analysts, including those affiliated with our underwriters from prior offerings, establish and publish their own periodic projections for our business. These projections may vary widely from one another and may not accurately predict the results we actually achieve. Our stock price may decline if our actual results do not match securities research analysts’ projections. Similarly, if one or more of the analysts who writes reports on us downgrades our stock or publishes inaccurate or unfavorable research about our business or if one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, our stock price or trading volume could decline. While we expect

Table of Contents

securities research analyst coverage to continue going forward, if no securities or industry analysts begin to cover us, the trading price for our stock and the trading volume could be adversely affected.

Our need for future financing may result in the issuance of additional securities that will cause investors to experience dilution.

Our cash requirements may vary from those now planned depending upon numerous factors, including the result of future research and development activities. We expect our expenses to increase in connection with our ongoing activities, particularly as we continue the research and development and initiate and conduct clinical trials of, and seek marketing approval for, our product candidates. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product sales, marketing, manufacturing and distribution. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. There are no other commitments by any person for future financing. Our securities may be offered to other investors at a price lower than the price per share offered to current stockholders, or upon terms that may be deemed more favorable than those offered to current stockholders. In addition, the issuance of securities in any future financing may dilute an investor’s equity ownership and have the effect of depressing the market price for our securities. Moreover, we may issue derivative securities, including options and/or warrants, from time to time, to procure qualified personnel or for other business reasons. The issuance of any such derivative securities, which is at the discretion of our board of directors, may further dilute the equity ownership of our stockholders. No assurance can be given as to our ability to procure additional financing, if required, and on terms deemed favorable to us. To the extent additional capital is required and cannot be raised successfully, we may then have to limit our then current operations and/or may have to curtail certain, if not all, of our business objectives and plans.

None.

Item 2. Properties

Facilities

Our executive offices are located at 627 Davis Drive, Suite 400, Morrisville, North Carolina 27560. In October 2019, we entered into a lease that expires October 31, 2027 for 7,492 square feet of office and laboratory space for monthly rent of $17,525 exclusive of payments required for maintenance of common areas and utilities.

In January 2018, Pelican entered into a five-year lease for 5,156 square feet of office and laboratory space located San Antonio, Texas for monthly rent of $9,668, exclusive of payments required for maintenance of common areas and utilities.

In July 2020, we entered into a lease for our Skunkworx subsidiary that is expected to expire July 1, 2022 for 1,300 square feet of laboratory space for monthly rent of $3,300 exclusive of payments required for utilities.

Item 3. Legal Proceedings

From time to time, we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We are not presently a party to any legal proceedings that, if determined adversely to us, would individually or taken together have a material adverse effect on our business, operating results, financial condition or cash flows. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchase of Equity

Market Information

Our common stock has traded on the Nasdaq Capital Market under the symbol “HTBX”.

Holders

As of March 22, 2021, there were approximately 11 stockholders of record of our common stock. The number of holders of record is based on the actual number of holders registered on the books of our transfer agent and does not reflect holders of shares in “street name” or persons, partnerships, associations, corporations or other entities identified in security position listings maintained by depository trust companies.

On December 10, 2020, we announced a reverse stock split of our shares of common stock at a ratio of one-for-seven. The reverse stock split took effect at 12:01 a.m. ET on December 11, 2020, and our common stock began to trade on a post-split basis at the market open on December 11, 2020. During our annual stockholders meeting held February 27, 2020, shareholders approved our company’s reverse stock split, and granted the board of directors the authority to implement and determine the exact split ratio. When the reverse stock split became effective, every seven shares of our issued and outstanding common stock were combined into one share of common stock. Effecting the reverse stock split reduced the number of issued and outstanding common stock on the effective date of the reverse split from approximately 159.8 million shares to approximately 22.8 million. It also subsequently adjusted outstanding options issued under our equity incentive plan and outstanding warrants to purchase common stock.

Dividend Policy

We have never paid any cash dividends on our common stock to date, and do not anticipate paying such cash dividends in the foreseeable future. Whether we declare and pay dividends is determined by our Board of Directors at their discretion, subject to certain limitations imposed under Delaware corporate law. The timing, amount and form of dividends, if any, will depend on, among other things, our results of operations, financial condition, cash requirements and other factors deemed relevant by our Board of Directors.

Company Overview

We are a biopharmaceutical company primarily engaged in the development of immune therapies and vaccines. Our gp96 platform is designed to activate the immune system. This platform has broad applications in cancer and infectious disease. Our platform leverages gp96’s role as a natural molecular warning system that presents antigens to the immune system. HS-110 (viagenpumatucel-L) is our first allogeneic (“off-the-shelf”) cell line biologic product candidate in a series of proprietary immunotherapies designed to stimulate a patient’s T-cells to destroy cancer. HS-130 is an allogeneic cell line engineered to express the extracellular domain of OX40 ligand fusion protein (OX40L-Fc), a key costimulator of T-cells, with the potential to augment antigen-specific CD4+ T-cell and CD8+ T-cell responses. We have initiated development of a new COVID-19 vaccine program under our Zolovax, Inc. subsidiary that utilizes our gp96 platform to secrete SARS-CoV-2 antigens. Our subsidiary Pelican Therapeutics, Inc. (“Pelican”), is developing PTX-35, a novel T-cell co-stimulator agonist antibody targeting TNFRSF25 for systemic administration.

These programs are designed to harness the body's natural antigen specific immune activation and tolerance mechanisms to reprogram immunity and provide a long-term, durable clinical effect. We have completed recruiting patients in our Phase 2 HS-110 non-small cell lung cancer (NSCLC) trial, dosed twelve patients in our Phase 1 clinical trial of HS-130 and dosed five patients in our Phase 1 clinical trial of PTX-35. We are also providing pre-clinical, CMC development, and administrative support for these operations; while constantly focusing on protecting and expanding our intellectual property in areas of strategic interest. As we advance our clinical programs, we are in close contact with our CROs and clinical sites and are assessing the impact of COVID-19 on our studies and current timelines and costs.

Our gp96 Platform includes ImPACT^® and ComPACT^™which are designed to activate and expand tumor antigen specific “killer” T-cells to destroy a patient’s cancer. By turning immunologically “COLD tumors HOT,” we believe our platform will become an essential component of the immuno-oncology regimen to enhance the effectiveness and durability of checkpoint inhibitors and other cancer therapies, thereby improving outcomes for those patients less likely to benefit from checkpoint inhibitors alone.

We believe this is a highly differentiated approach as our platform delivers a broad range of tumor antigens that are previously unrecognized by the patient’s immune system. Our platform combines these tumor antigens with a powerful, naturally occurring immune adjuvant, gp96, to actively chaperone these antigens. Our gp96 product candidates are non-replicating, “off-the-shelf”, allogenic cell-based therapies that are locally administered into the skin. The treatment is designed to prime local natural immune recognition to activate T-cells to seek and destroy the cancer cells throughout the body. These agents can be administered with a variety of immuno-modulators to enhance a patient’s immune response through T-cell activation.

Unlike many other “patient specific” or autologous immunotherapy approaches, our drugs are fully allogenic, “off-the-shelf” products which means that we can administer drug immediately without the extraction of blood or tumor tissue from each patient or the creation of an individualized treatment based on patient materials. Our gp96 product candidates are produced from allogeneic cell lines expressing tumor-specific proteins common among cancers. Because each patient is dosed with the same medication, we believe that our immunotherapy approach offers superior speed to initiation, logistical, manufacturing and importantly, cost benefits, compared to “personalized” precision medicine approaches.

Our ImPACT^® platform is an allogenic cell-based, T-cell-stimulating platform that functions as an immune activator to stimulate and expand T-cells. The key component of this innovative immunotherapy platform is the dual functionality of the heat shock protein, gp96.

Table of Contents

of the gp96-chaperoned tumor associated peptide antigens directly to MHC class I molecules for direct activation and expansion of CD8+ T-cells. Thus, gp96 plays a critical role in the mechanism of action for our T-cell activating platform immuno-therapies; mimicking necrotic cell death and activating a powerful, tumor antigen-specific T-cell immune response to attack the patient’s cancer cells.

ComPACT^™, our second gp96-based program, delivers antigen-driven T-cell activation and specific co-stimulation in a single product by providing specific co-stimulation to enhance T-cell activation and expansion. This approach has the potential to simplify combination immunotherapy development for oncology patients, as it is designed to deliver the gp96 heat shock protein and a T-cell co-stimulatory fusion protein (OX40L) as a single therapeutic, without the need for multiple, independent biologic products. This dual approach has several potential advantages including: (a) enhanced activation of antigen-specific CD8+ T-cells; (b) boosting the number of antigen-specific CD8+ and CD4+ T-cells compared to OX40L alone; (c) stimulation of T-cell memory function to remain effective after treatment, even if the cancer comes back; (d) demonstration of less toxicity, as the source of cancer associated antigens and co-stimulator are supplied at the same time locally in the draining lymph nodes, which drives targeted, cancer specific immunity towards the tumor rather than throughout the body; and (e) simplification of combination cancer immunotherapy versus systemic co-stimulation with conventional monoclonal antibodies (mAbs).

Pelican, our subsidiary, is a biotechnology company focused on developing an agonist mAb, PTX-35, against a T-cell costimulatory receptor, TNFRSF25. PTX-35 has completed IND-enabling activities in preparation for a first-in-human (FIH) trial for oncology. Pelican has initiated its first clinical trial site for PTX-35 and began dosing patients in the Phase 1 clinical trial. PTX-35 is designed to harness the body's natural antigen specific immune activation and tolerance mechanisms to reprogram immunity and provide a long-term, durable clinical effect. TNFRSF25 agonism has been shown to provide highly selective and potent stimulation of antigen experienced ‘memory’ CD8+ cytotoxic T-cells, which are the class of long-lived T-cells capable of eliminating tumor cells in patients. Due to the preferential specificity of PTX-35 to antigen experienced CD8+ T-cells, this agent represents a promising candidate as a T-cell co-stimulator in cancer patients.

When combined in preclinical studies with Heat’s gp96 platform immunotherapies and an inti-PD-1 checkpoint inhibitor, PTX-35 has been shown to enhance antigen specific T-cell activation to eliminate tumor cells. Pelican is also developing other biologics that target TNFRSF25 for various immunotherapy approaches.

We continue to enroll patients in our HS-110 combination immunotherapy trial, preparing for IND submission of HS-130 (ComPACT^™), advancing pre-clinical development of Pelican assets in anticipation of an IND submission, providing general and administrative support for these operations and protecting our intellectual property. We currently do not have any products approved for sale and we have not generated any significant revenue since our inception and no revenue from product sales. We expect to continue to incur significant expenses and to incur increasing operating losses for at least the next several years. We anticipate that our expenses will increase substantially as we:

●

complete the ongoing clinical trials of our product candidates;

●

maintain, expand and protect our intellectual property portfolio;

●

seek to obtain regulatory approvals for our product candidates;

●

continue our research and development efforts;

●

add operational, financial and management information systems and personnel, including personnel to support our product development and commercialization efforts; and

●

operate as a public company.

Recent Clinical Developments

On February 9, 2021, we announced positive interim data from Phase 2 trial. Substantial survival benefit was observed in a cohort of previously treated, checkpoint inhibitor naïve patients with advanced NSCLC (Cohort A, N = 47). A median progression free survival (PFS) of 1.8 months and a median overall survival (OS) of 24.6 months was observed with a median follow-up time of 19.4 months. The one-year survival rate of Cohort A is 61.7%. The median OS data was 12.2 months and the 1-year survival rate was 50.7% in previously treated, advanced NSCLC patients who received nivolumab as a single agent, according to published data of the BMS CheckMate 057 study.

In November 2020, our CPRIT Grant, initially covering a period from June 1, 2016 through November 30, 2020, as amended, was extended to May 31, 2021.

●

On December 10, 2020, we announced a reverse stock split of our shares of common stock at a ratio of 1-for-7.

Funding/Liquidity

We commenced active operations in June 2008. Our operations to date have been primarily limited to organizing and staffing our company, business planning, raising capital, acquiring and developing our technology, identifying potential product candidates and undertaking preclinical and clinical studies of our most advanced product candidates. To date, we have primarily financed our operations with net proceeds from the sale of our securities including, our July 2013 initial public offering in which we received net proceeds of $24.3 million, our March 2015 public offering in which we received net proceeds of $11.1 million, our March 2016 public offering in which we received net proceeds of $6.1 million, an additional $3.9 million from the exercise of warrants, our March 2017 public offering in which we received net proceeds of approximately $4.1 million, our November 2017 public offering in which we received net proceeds of approximately $2.4 million, our May 2018 public offering in which we received net proceeds of approximately $18.8 million and an additional $4.8 million from the exercise of warrants, our November 2018 public offering in which we received net proceeds of approximately $12.7 million and our January 21, 2020 public offering of shares of our common stock and warrants to purchase shares of our common stock in which we received net proceeds of approximately $6.4 million. As of December 31, 2020, we have received $13.7 million in grant funding from the CPRIT Grant through Pelican. We have also raised an aggregate of $114.4 million through at-the-market offerings for the year ended December 31, 2020. Subsequent to the year ended December 31, 2020, we have issued an additional 2,106,027 shares of common stock in “at-the-market” offerings and received $25.6 million of net proceeds. Cash and cash equivalents at March 22, 2021 were approximately $132.0 million. As of December 31, 2020, we had an accumulated deficit of $130.6 million. We had net losses of $26.4 million and $20.4 million for the years ended December 31, 2020 and 2019, respectively.

We expect to continue to incur significant expenses and continued losses from operations for the foreseeable future. We expect our expenses to increase in connection with our ongoing activities, particularly as we continue the research and development and advance our clinical trials of, and seek marketing approval for, our product candidates and as we add to our product candidate pipeline. In addition, if we expand our operations we will incur additional expenses which could be significant. Furthermore, if we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product sales, marketing, manufacturing, and distribution. As currently planned, we expect to have sufficient funds to fund our operations into 2024. We will need to obtain substantial additional future funding in connection with our future planned clinical trials and any new opportunities we may pursue. While we are currently funding vaccine development and preclinical studies, we do not expect to use significant corporate resources to advance our COVID-19 program. We are applying for several large grants to support clinical development of this program and are engaged in collaboration discussions, which we believe may provide attractive and non-dilutive pathways to help accelerate development of our COVID-19 program; however, there can be no assurance that we will receive such grant funding or if received, the amount of such grant funding. Adequate additional financing may not be available to us on acceptable terms, or at all. To meet our capital needs, we are considering multiple alternatives, including, but not limited to, additional equity financings, which include sales of our common stock under at-the-market offerings, if available, debt

financings, partnerships, collaborations and other funding transactions. This is based on our current estimates, and we could use our available capital resources sooner than we currently expect. We will need to generate significant revenues to achieve profitability, and we may never do so.

CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT JUDGMENTS AND ESTIMATES

We believe that several accounting policies are important to understanding our historical and future performance. We refer to these policies as "critical" because these specific areas generally require us to make judgments and estimates about matters that are uncertain at the time we make the estimate, and different estimates—which also would have been reasonable—could have been used, which would have resulted in different financial results.

Our management’s discussion and analysis of financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of our consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates based on historical experience and make various assumptions, which management believes to be reasonable under the circumstances, which form the basis for judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

The notes to our audited consolidated financial statements contain a summary of our significant accounting policies. We consider the following accounting policies critical to the understanding of the results of our operations:

●

Revenue;

●

Deferred revenue;

●

In-process R&D;

●

Goodwill impairment;

●

Income tax;

●

Contingent consideration;

●

Stock-based compensation;

●

Derivative financial instruments;

●

Research and development costs, including clinical and regulatory cost; and

●

Recent accounting pronouncements.

Revenue

Our 2020 and 2019 revenue primarily consisted of research funding from our CPRIT Grant. Grant revenue is recognized when qualifying costs are incurred and there is reasonable assurance that the conditions of the award have been met for collection. Proceeds received prior to the costs being incurred or the conditions of the award being met are recognized as deferred revenue until the services are performed and the conditions of the award are met.

Deferred Revenue

Deferred revenue is comprised of proceeds of $0.6 million received from CPRIT for which the costs have not been incurred or the conditions of the award have not been met and grant funds received from an economic development grant agreement with the City of San Antonio (“Economic Development Grant”) that we entered into on November 1, 2017. Under the Economic Development Grant, we received $0.2 million in state enterprise fund grants for the purpose of defraying costs toward the purchase of laboratory equipment. As part of the agreement, we will provide the city of San Antonio with a purchase money security interest in the equipment to secure the repayment of grant funds should we fail to perform under the terms and conditions of the agreement. Our obligations under the agreement include meeting certain employment levels for a period of not less than seven years commencing on or before December 31, 2017 and establishing Pelican’s corporate headquarters in San Antonio. The Economic Development Grant funds will be recognized as income upon the achievement of the performance criteria and determination that the cash is no longer refundable to the State of Texas.

Table of Contents

In-process R&D

In-process research and development (“IPR&D”) assets represent the fair value assigned to technologies that were acquired, which at the time of acquisition have not reached technological feasibility and have no alternative future use. IPR&D assets are considered to be indefinite-lived until the completion or abandonment of the associated research and development projects. During the period that the IPR&D assets are considered indefinite-lived, they are tested for impairment on an annual basis, or more frequently if the Company becomes aware of any events occurring or changes in circumstances that indicate that the fair value of the IPR&D assets are less than their carrying amounts. If and when development is complete, which generally occurs upon regulatory approval, and the Company is able to commercialize products associated with the IPR&D assets, these assets are then deemed definite-lived and are amortized based on their estimated useful lives at that point in time. If development is terminated or abandoned, the Company may have a full or partial impairment charge related to the IPR&D assets, calculated as the excess of carrying value of the IPR&D assets over fair value. The IPR&D assets were acquired on April 28, 2017 when we acquired Pelican.

Goodwill and Impairment

Goodwill is tested for impairment annually or more frequently if changes in circumstances or the occurrence of events suggest that impairment may exist. We use widely accepted valuation techniques to determine the fair value of its reporting units used in its annual goodwill impairment analysis. Our valuation is primarily based on qualitative and quantitative assessments regarding the fair value of the reporting unit relative to its carrying value. See Note 7 to the consolidated financial statements regarding impairment at December 31, 2019.

Income Tax

Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the carrying amounts of assets and liabilities and their respective tax bases, operating loss carryforwards, and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

In accordance with FASB ASC 740, Accounting for Income Taxes, we reflect in the financial statements the benefit of positions taken in a previously filed tax return or expected to be taken in a future tax return only when it is considered ‘more-likely-than-not’ that the position taken will be sustained by a taxing authority. As of December 31, 2020 and 2019, we had no unrecognized income tax benefits and correspondingly there is no impact on our effective income tax rate associated with these items. Our policy for recording interest and penalties relating to uncertain income tax positions is to record them as a component of income tax expense in the accompanying consolidated statements of operations and comprehensive loss. As of December 31, 2020 and 2019, we had no such accruals.

Contingent Consideration

Contingent consideration is recorded as a liability and is the estimate of the fair value of potential milestone payments related to business acquisitions. Contingent consideration is measured at fair value using a discounted cash flow model utilizing significant unobservable inputs including the probability of achieving each of the potential milestones and an estimated discount rate associated with the risks of the expected cash flows attributable to the various milestones. Significant increases or decreases in any of the probabilities of success or changes in expected timelines for achievement of any of these milestones would result in a significantly higher or lower fair value of these milestones, respectively, and commensurate changes to the associated liability. The contingent consideration is revalued at each reporting period and changes in fair value are recognized in the consolidated statements of operations and comprehensive loss.

Stock-Based Compensation

Calculating stock-based compensation expense requires the input of highly subjective assumptions. The fair value of restricted stock units is estimated based on the closing price of our stock on the date of grant, and for the purposes of

Table of Contents

expense recognition, the total new number of shares expected to vest is adjusted for estimated forfeitures. We apply the Black-Scholes-Merton option pricing model to determine the fair value of our stock options awards. Inherent in this model are assumptions related to expected stock-price volatility, expected option life, risk-free interest rate and dividend yield. We use an average historical stock price volatility of our own data plus an analysis of reported data for a peer group of comparable companies that have issued stock options with substantially similar terms. We estimate the expected life of our options using the simplified method. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected life of the options. The dividend rate is based on our historical rate, which we anticipate to remain at zero. We account for forfeitures as they occur. The assumptions used in calculating the fair value of stock options represent our best estimates, however these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and different assumptions are used, the stock-based compensation expense could be materially different in the future.

Derivative Financial Instruments

We issued common stock warrants in connection with the execution of certain equity financings. The fair value of the warrants, which were deemed to be derivative instruments, was recorded as a derivative liability under the provisions of ASC Topic 815 Derivatives and Hedging (“ASC 815”) because they are not considered indexed to the Company’s own stock. Subsequently, the liability is adjusted to fair value as of the end of each reporting period and the changes in fair value of derivative liabilities are recorded in the consolidated statements of operations and comprehensive loss under the caption “Change in fair value of warrant liability.” See Note 2 to the consolidated financial statements for additional information.

Research and Development Costs

We expense research and development costs associated with developmental products not yet approved by the FDA as well as costs associated with bringing our developmental products into advanced phase clinical trials as incurred. These costs consist primarily of pre-manufacturing and manufacturing drug costs, clinical trial execution, investigator payments, license fees, salaries, stock-based compensation and related personnel costs. Other costs include fees paid to consultants and outside service providers related to the development of our product candidates, and other expenses relating to the design, development, and testing and enhancement of our product candidates.

Recent Accounting Pronouncements

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses which requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. This standard is effective for fiscal years beginning after December 15, 2022 and the Company is currently evaluating the expected impact of this standard but does not expect it to have a material impact on its consolidated financial statements upon adoption.

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (ASU 2019-12), which simplifies the accounting for income taxes by removing certain exceptions to the general principles of Topic 740, Income Taxes, and also improves consistency of application by clarifying and amending existing guidance. ASU 2019-12 is effective for fiscal years beginning after December 15, 2020, with early adoption permitted. The Company is currently evaluating the expected impact of this standard but does not expect it to have a material impact on its consolidated financial statements upon adoption.

In January 2020, the FASB issued ASU 2020-01, Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)-Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (a consensus of the Emerging Issues Task Force), which addresses the accounting for the transition into and out of the equity method and measuring certain purchased options and forward contracts to acquire investments. ASU 2020-01 is effective for fiscal years beginning after December 15, 2020, with early adoption permitted. The Company is currently evaluating the expected impact of this standard but does not expect it to have a material impact on its consolidated financial statements upon adoption.

In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. This ASU simplifies the accounting for convertible instruments. This ASU also requires entities to use the if-converted method for all convertible instruments in calculating diluted earnings-per-share. The ASU is effective for annual periods beginning after December 15, 2021 with early adoption permitted. We are currently evaluating the impact this standard will have on our consolidated financial statements.

RESULTS OF OPERATIONS

Year Ended December 31, 2020 and 2019

Revenues

The CPRIT Grant is subject to customary CPRIT funding conditions including a matching funds requirement where Pelican will match $0.50 for every $1.00 from CPRIT. Consequently, Pelican is required to raise $7.6 million in matching funds over the life of the project.

As of December 31, 2020, CPRIT has provided $13.7 million of the total $15.2 million grant. The remaining $1.5 million will become available on a reimbursement basis, rather than in advance of expending the funds as in prior grant years. As of December 31, 2020, we have provided approximately $6.6 million which was used to satisfy Pelican’s matching fund obligation under the first four years of the CPRIT Grant and we have approximately $1.0 million remaining to provide for the fifth CPRIT fiscal year.

Upon commercialization of the product, the terms of the Grant Contract require Pelican to pay tiered royalties in the low to mid-single digit percentages. Such royalties reduce to less than one percent after a mid-single-digit multiple of the grant funds have been paid to CPRIT in royalties.

We recognized grant revenue of approximately $2.8 million for the year ended December 31, 2020 for qualified expenditures under the grant. We recognized $3.0 million grant revenue related to CPRIT during the year ended December 31, 2019. As of December 31, 2020, we had short-term deferred revenue of $0.6 million for proceeds received but for which the costs had not been incurred or the conditions of the award had not been met.

Operating Expenses

Total operating expenses for the years ended December 31, 2020 and 2019, were $29.1 million and $23.8 million, respectively. For the year ended December 31, 2020 operating expenses are primarily comprised of research and development, general and administrative expenses, and a change in the fair value of contingent consideration due to our initial acquisition of a controlling interest in Pelican in 2017. Research and development expenses were $12.9 million, general and administrative expenses were $14.9 million and the change in fair value of contingent consideration was $1.2 million for the year ended December 31, 2020 as compared to research and development expenses of $13.0 million, general and administrative expenses of $9.4 million, goodwill impairment loss of $0.7 million and the change in fair value of contingent consideration of $0.6 million for the year ended December 31, 2019. For the year ended December 31, 2020, research and development expenses represented approximately 45% of operating expenses, general and administrative expenses represented approximately 51% and change in fair value of contingent consideration 4% of operating expenses. For the year ended December 31, 2019, research and development expenses represented approximately 55% of operating expenses, general and administrative expenses represented approximately 39%, goodwill impairment represented approximately 3% and change in fair value of contingent consideration 3% of operating expenses.

Table of Contents

Research and development expense

Research and development expenses stayed consistent at $12.9 million and $13.0 million for the years ended December 31, 2020 and December 31, 2019. The components of R&D expense are as follows, in millions:


	Year ended December 31,
	2020		2019
Programs
HS-110	$	1.3	$	0.1
HS-130		0.8		0.4
PTX 35/other biologics against TNFRSF25		2.0		3.0
COVID-19		0.5		—
Other programs		0.5		3.3
Unallocated research and development expenses		7.8		6.2
	$	12.9	$	13.0

●

HS-110 increased by $1.2 million, reflecting the current period mix of development activities, primarily due to increased costs associated with manufacturing and testing.

●

HS -130 expense increased by $0.4 million due to dosing of patients during the year ended 2020 and third-party regulatory consulting and investigator site payments for the ongoing Phase 1 clinical trial.

●

PTX-35 expense decreased by $1.0 primarily due to the transition from pre-clinical development to manufacturing development and patient dosing.

●

COVID-19 program was initiated in Q1 2020 and primarily represents sponsored research agreement costs.

●

Other programs include preclinical costs associated with our Zika program, T-cell costimulatory programs, and laboratory supplies.

●

Unallocated research expenses primarily reflects personnel costs, including stock-based compensation from stock awards.

General and administrative expense

General and administrative expense increased approximately 59% to $14.9 million for the year ended December 31, 2020 compared to $9.4 million for the year ended December 31, 2019. The increase of $5.5 million is primarily due to the increase in personnel and the CEO’s stock compensation expense on awards with an immediate vest date.

Change in fair value of contingent consideration

We reassess the actual consideration earned and the probability-weighted future earn-out payments at each balance sheet date. The change in the fair value of contingent consideration was $1.2 million for the year ended December 31, 2020 compared to the change in fair value of contingent consideration of $0.6 million for the year ended December 31, 2019. The change was primarily due to the effect of the change in discount rate, the payment of the first milestone, probability of achieving milestones, and passage of time on the fair value measurement.

Goodwill impairment loss

During the year ended December 31, 2019, the Company experienced a sustained decline in the quoted market price of the Company’s common stock and as a result the Company determined that it was more likely than not that the carrying value of these acquired intangibles exceeded their estimated fair value. Accordingly, the Company performed an impairment analysis using the income approach. This analysis required significant judgments, including primarily the estimation of future development costs, the probability of success in various phases of its development programs, potential post-launch cash flows and a risk-adjusted weighted average cost of capital. As a result, the Company recorded an impairment loss of $0.7 million on the goodwill during the year ended December 31, 2019. No impairment was recorded during the year ended December 31, 2020.

Table of Contents

Change in fair value of warrant liability

During the year ended December 31, 2020 the Company issued common stock warrants in connection with the execution of certain equity financings. The fair value of the warrants, which were deemed to be derivative instruments, were recorded as a derivative liability and was adjusted to fair value at the end of the reporting period resulting in $1.0 million of warrant expense. There were no derivative liabilities for the year ended December 31, 2019.

Interest Income

Interest income was $0.6 million for the year ended December 31, 2020 compared to $0.4 million for the year ended December 31, 2019. The increase is due to the investment in various short-term financial instruments that generated interest income during the year ended December 31, 2020.

Income tax expense

There was no income tax expense for the year ended December 31, 2020 compared to $0.04 million for the year ended December 31, 2019.

Net loss attributable to Heat Biologics, Inc.

We had a net loss attributable to Heat Biologics, Inc. of $26.0 million, or ($1.63) per basic and diluted share for the year ended December 31, 2020 compared to a net loss attributable to Heat Biologics, Inc. of $20.0 million, or ($4.21) per basic and diluted share for the year ended December 31, 2019.

BALANCE SHEET AS OF DECEMBER 31, 2020 AND 2019

Short-term Investments. Short-term investments were $100.8 million as of December 31, 2020 compared to $5.7 million as of December 31, 2019. The increase is primarily due to the Company using the proceeds from the sale of common stock through an at-the-market Common Stock Sales Agreement with B. Riley FBR, Inc. and Cantor Fitzgerald & Co. in purchasing short-term investments.

Prepaid Expenses and Other Current Assets. Prepaid expenses and other current assets was approximately $1.8 million as of December 31, 2020 and $0.4 million as of December 31, 2019. The $1.4 million increase was primarily attributable to our upfront D&O and liability insurance and manufacturing deposits.

In-Process R&D. As of December 31, 2020 and December 31, 2019, we had in-process R&D of $5.9 million from our acquisition of Pelican. The carrying value of this asset did not change during the year ended December 31, 2020.

Goodwill. As of December 31, 2020 and December 31, 2019, we had goodwill of $1.5 million, respectively, from our acquisition of Pelican. The carrying value of this asset did not change during the year ended December 31, 2020.

Accounts Payable. Accounts payable was approximately $1.1 million and $1.5 million as of December 31, 2020 and December 31, 2019. The $0.4 million decrease was primarily due to lower payables for investigator site payments for our clinical trials.

Deferred Revenue. We had short term deferred revenue of $0.6 million and $3.4 million as of December 31, 2020 and December 31, 2019, respectively. This short term deferred revenue represents proceeds received for the CPRIT grant but for which the costs had not been incurred or the conditions of the award had not been met. We had long term deferred revenue of $0.2 million as of December 31, 2020 and 2019, related to an economic development grant received from San Antonio for the purchase of lab equipment.

Accrued Expenses and Other Liabilities. Accrued expenses were approximately $1.6 million at December 31, 2020 compared to $1.7 million at December 31, 2020. The decrease is primarily due to lower clinical accruals.

Table of Contents

Operating and financing lease liabilities. Current and long term liabilities related to operating and finance leases was $1.8 million as of December 31, 2020 and $1.9 million as of December 31, 2019. These balances are related to our office lease and equipment leases.

Deferred Tax Liability. Deferred tax liability was approximately $0.4 million for the years ended December 31, 2020 and December 31, 2019.

Contingent Consideration. As of December 31, 2020, we had contingent consideration of $2.9 million compared to $3.7 million for the year ended December 31, 2019 related to our acquisition of Pelican which is recorded on our consolidated balance sheets. This amount represents the fair value of future milestone payments to Pelican shareholders which were discounted in accordance with ASC 805. We perform an analysis on a quarterly basis and for the year ended December 31, 2020, we determined the change in the estimated fair value of the contingent consideration to be approximately $1.2 million due to the effect of the change in discount rate, the payment of the first milestone, probability of achieving milestones, and passage of time on the fair value measurement.

LIQUIDITY AND CAPITAL RESOURCES

Sources of Liquidity

Since our inception in June 2008, we have incurred significant losses and we have financed our operations with net proceeds from the private placement of our preferred stock, common stock and debt. Since our initial public offering, we have primarily financed our operations with net proceeds from the public offering of our securities and to a lesser extent, the proceeds from the exercise of warrants. During May 2018, we closed a public offering of shares of our common stock and warrants to purchase shares of our common stock in which we received net proceeds of approximately $18.8 million and after the closing of the offering, an additional $4.8 million from the exercise of 436,381 warrants issued in this offering. During November 2018, we closed a public offering of shares of our common stock and warrants to purchase shares of our common stock in which we received net proceeds of approximately $12.7 million. For the year ended December 31, 2018 and 2019, we received net proceeds of approximately $3.8 million from sales of our common stock in at-the-market offerings. On January 21, 2020, we closed an underwritten public offering of shares of our common stock and warrants to purchase shares of our common stock pursuant to which we received net proceeds of approximately $6.4 million. For the year ended December 31, 2020, we received net proceeds of $114.4 million from the sale of 13,175,677 shares of our common stock in at-the-market offerings. Subsequent to the year ended December 31, 2020, we have issued an additional 2,106,027 shares of common stock in “at-the-market” offerings and received $25.6 million of net proceeds. As of December 31, 2020, we had an accumulated deficit of approximately $130.6 million. We had net losses of $26.4 million and $20.4 million for the years ended December 31, 2020 and 2019, respectively.

We expect to incur significant expenses and continued losses from operations for the foreseeable future. We expect our expenses to increase in connection with our ongoing activities, particularly as we continue the research and development and advance our clinical trials of, and seek marketing approval for, our product candidates and as we add to our product candidate pipeline. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product sales, marketing, manufacturing, and distribution. Although we currently have sufficient funds to complete our Phase 2 clinical trials, as currently planned, and expect that we will have sufficient funds to fund our operations into 2024, we will need to obtain substantial additional future funding in connection with our future planned clinical trials. While we are currently funding vaccine development and preclinical studies, we do not expect to use significant corporate resources to advance our COVID-19 program. We are applying for several large grants to support clinical development of this program and are engaged in collaboration discussions, which we believe may provide attractive and non-dilutive pathways to help accelerate development of our COVID-19 program; however, there can be no assurance that we will receive such grant funding or if received, the amount of such grant funding. Adequate additional financing may not be available to us on acceptable terms, or at all. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce or eliminate our research and development programs or any future commercialization efforts. To meet our capital needs, we are considering multiple alternatives, including, but not limited to, additional equity financings, which include sales of our common stock under at-the-market offerings, if available, debt financings, partnerships, collaborations and other funding transactions. This is based on our current estimates, and we could use our available capital resources sooner than we currently expect. We will need to generate

Table of Contents

significant revenues to achieve profitability, and we may never do so. As of December 31, 2020, we had approximately $111.8 million in cash and cash equivalents and short-term investments.

Cash Flows

Operating activities. The use of cash in both periods resulted primarily from our net losses adjusted for non-cash charges and changes in components of working capital. Net cash used in operating activities during the year ended December 31 2020 was $22.0 million compared to $12.8 million during the same period in 2019. The increase was primarily due to an increase in net loss of $6.0 million, prepaid expense and other current assets of $1.4 million, and changes in deferred revenue and accounts payable of $3.2 million, offset by an increase in non-cash stock-based compensation of $3.1 million and increase in the fair value of warrants and contingent consideration of $1.6 million.

Investing activities. Net cash used in investing activities was $95.4 million during year ended December 31, 2020 compared to $0.3 million during the same period in 2019. The increase is from the net purchase of short-term investments of $95.1 million.

Financing activities. Net cash provided by financing activities was $119.3 million during the year ended December 31, 2020 compared to $0.02 million during the year ended December 31, 2019. The increase was primarily due to a public offering of common stock and warrants of $6.6 million, sale of our common stock through an at-the-market Common Stock Sales Agreement with B. Riley FBR, Inc. and Cantor Fitzgerald & Co. for $117.4 million, proceeds from the exercise of warrants of $0.7 million, partially offset by stock issuance costs of $3.1 million, , payment of contingent consideration of $2.0 million, and principal payments on finance lease of $0.1 million.

On April 23, 2020, Heat and Pelican received loan proceeds of $0.7 million from Regions Bank, N.A, pursuant to the Paycheck Protection Program, or the PPP Loan, under the CARES Act, administered by the U.S. Small Business Administration. On April 28, 2020, we returned all $0.7 million in proceeds from the PPP Loan in order to make those funds available to other borrowers that may be in greater need.

OFF-BALANCE SHEET ARRANGEMENTS

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined under SEC rules.

Current and Future Financing Needs

We have incurred an accumulated deficit of $130.6 million through December 31, 2020. We have incurred negative cash flows from operations since we started our business. We have spent, and expect to continue to spend, substantial amounts in connection with implementing our business strategy, including our planned product development efforts, our clinical trials, and our research and discovery efforts.

We intend to meet our financing needs through multiple alternatives, including, but not limited to, cash on hand, additional equity financings, debt financings and/or funding from partnerships or collaborations.

However, the actual amount of funds we will need to operate is subject to many factors, some of which are beyond our control. These factors include the following:

●

the progress of our research activities;

●

We have based our estimate on assumptions that may prove to be wrong. We may need to obtain additional funds sooner or in greater amounts than we currently anticipate. Potential sources of financing include strategic relationships, public or private sales of our equity or debt and other sources. We may seek to access the public or private equity markets when conditions are favorable due to our long-term capital requirements. We do not have any committed sources of financing at this time, and it is uncertain whether additional funding will be available when we need it on terms that will be acceptable to us, or at all. If we raise funds by selling additional shares of common stock, such as through the Amended and Restated Common Stock Sales Agreement with B. Riley FBR, Inc. and Cantor Fitzgerald & Co., or other securities convertible into common stock, the ownership interest of our existing stockholders will be diluted. If we are not able to obtain financing when needed, we may be unable to carry out our business plan. As a result, we may have to significantly limit our operations and our business, financial condition and results of operations would be materially harmed. While we are experiencing limited financial impacts at this time, given the global economic slowdown, the overall disruption of global healthcare systems and the other risks and uncertainties associated with the pandemic, our business, financial condition, results of operations and growth prospects could be materially adversely affected.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

Our management has adopted and maintains disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed in the reports filed under the Exchange Act, such as this Annual Report, is collected, recorded, processed, summarized and reported within the time periods specified in the rules of the SEC. Our disclosure controls and procedures are also designed to ensure that such information is accumulated and communicated to management to allow timely decisions regarding required disclosure. As required under Exchange Act Rule 13a-15, our management, including the Principal Executive Officer and Principal Financial Officer has conducted an evaluation of the effectiveness of disclosure controls and procedures as of the end of the period covered by this report. Based upon that evaluation, our Principal Executive Officer and Principal Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of December 31, 2020.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Exchange Act Rule 13a-15. Our internal control over financial reporting is designed to provide reasonable assurance to our management and Board of Directors regarding the preparation and fair presentation of published financial statements. Management conducted an assessment of our internal control over financial reporting based on the framework and criteria established by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control-Integrated Framework (2013). Based on the assessment, management concluded that, as of December 31, 2020, our internal controls over financial reporting were effective at the reasonable assurance level based on those criteria.

Our management, including our Principal Executive Officer and Principal Financial Officer, does not expect that our disclosure controls and procedures and our internal control processes will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of error or fraud, if any, within our company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that the breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and may not be detected. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk.

This Annual Report does not include an attestation report of the Company’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Company’s registered public accounting firm pursuant to rules of the SEC that permit the Company to provide only management’s report in this Annual Report.

Changes in Internal Control over Financial Reporting

There were no changes in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that occurred during our last quarter ended December 31, 2020 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Committees of the Board of Directors

The Board of Directors has a standing Audit Committee, Compensation Committee, and Nominating and Governance Committee. The following table shows the directors who are currently members or Chairman of each of these committees.

Audit Committee

Our common stock is listed on the Nasdaq Capital Market. Under the rules of Nasdaq, independent directors must comprise a majority of a listed company’s board of directors and all members of our audit, compensation and nominating and governance committees must be independent. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act. Under the rules of the Nasdaq Stock Market, a director will only qualify as an “independent director” if, in the opinion of that company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

In order to be considered to be independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee: (1) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries or (2) be an affiliated person of the listed company or any of its subsidiaries.

Our Board undertook a review of its composition, the composition of its committees and the independence of each director. Based upon information requested from and provided by each director concerning his background, employment and affiliations, including family relationships, our Board has determined that Dr. Monahan, Mr. Smith and Dr. Prendergast, representing three of our four directors, do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined under the rules of the Nasdaq Stock Market. In making this determination, our Board considered the relationships that each non-employee director has with us and all other facts and circumstances our Board deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director. We intend to comply with the other independence requirements for committees within the time periods specified above

Dr. Monahan, Mr. Smith, and Dr. Prendergast currently serve as members of the Audit Committee. The Board has determined that Dr. Monahan, Mr. Smith and Dr. Prendergast are each “independent” in accordance with the Nasdaq definition of independence and each is an “audit committee financial expert”, as defined by the SEC regulations, and each has the related financial management expertise within the meaning of the Nasdaq rules. The primary purpose of the Audit Committee is to act on behalf of the Board of Directors in its oversight of all material aspects of our accounting and financial reporting processes, internal controls and audit functions, including our compliance with Section 404 of the

Table of Contents

Sarbanes-Oxley Act of 2002. Pursuant to its charter, our Audit Committee reviews on an on-going basis for potential conflicts of interest, and approves if appropriate, all our “Related Party Transactions.” For purposes of the Audit Committee Charter, “Related Party Transactions” shall mean those transactions required to be disclosed pursuant to SEC Regulation S-K, Item 404. In addition, the Audit Committee reviews, acts on and reports to the Board of Directors with respect to various auditing and accounting matters, including the selection of the Company’s independent registered public accounting firm, the scope of the annual audits, fees to be paid to the independent registered public accounting firm, the performance of the Company’s independent registered public accounting firm and the accounting practices of the Company and the Company’s internal controls and legal compliance functions. The Committee also reviews, prior to publication, our quarterly earnings releases and our reports to the Securities and Exchange Commission on Forms 10-K and 10-Q. The Audit Committee operates pursuant to a written charter adopted by the Board of Directors, which is available on the Company’s website at www.heatbio.com. The charter describes the nature and scope of responsibilities of the Audit Committee.

Compensation Committee

Our Compensation Committee is comprised of Dr. Monahan, Mr. Smith, and Dr. Prendergast, each of whom is deemed to be independent in accordance with the Nasdaq definition of independence. Compensation Committee members must also satisfy the independence criteria set forth in Rule 10C-1 under the Exchange Act. This Committee determines, approves, and reports to the Board of Directors on all elements of compensation of our executive officers. The Compensation Committee also has the power to prescribe, amend, and rescind rules relating to our stock incentive plans, to recommend the grant of options and other awards under the stock incentive plans, and to interpret the stock incentive plans.

The Compensation Committee operates under a formal charter that governs its duties and standards of performance. A copy of the charter is available on our website at www.heatbio.com.

Our Compensation Committee annually reviews the compensation program for our Chief Executive Officer and other members of senior management and then makes recommendations to the full board for determination. In each case, the Committee takes into account the results achieved by the executive, his or her future potential, and his or her scope of responsibilities and experience. During our fiscal year ended December 31, 2020, the Committee evaluated the performance of our executives and considered the compensation levels and equity programs at comparable companies and related industries and the analysis of its outside consultant before it made its compensation recommendations to the full board, including recommendations regarding salary increases, awards of cash bonuses and awards of stock options.

The Committee administers our equity incentive plans, including review and recommendation of long-term incentive compensation for each executive, director and employee, including grants of stock options. The Committee believes that this long-term incentive compensation aligns the interests of our executives with those of our stockholders and furthers executive retention.

The Committee also reviews and recommends to the Board of Directors appropriate director compensation programs for service as directors, committee chairs and committee members.

Nominating and Governance Committee

The Nominating and Governance Committee is comprised of Dr. Monahan, Mr. Smith, and Dr. Prendergast.

The functions performed by the Nominating and Governance Committee include:

●

recommending to the Board of Directors individuals for appointment to vacancies on any committee of the Board of Directors;

●

recommending to the Board of Directors regarding any changes to the size of the Board of Directors or any committee;

●

reporting to the Board of Directors on a regular basis; and

●

performing any other duties or responsibilities expressly delegated to the committee by the Board of Directors relating to board or committee members.

Table of Contents

Candidates for director should have certain minimum qualifications, including the ability to understand basic financial statements, being over 21 years of age, having relevant business experience (taking into account the business experience of the other directors), and having high moral character. The Committee retains the right to modify these minimum qualifications from time to time.

In evaluating an incumbent director whose term of office is set to expire, the Nominating and Governance Committee reviews such director’s overall service to the Company during such director’s term, including the number of meetings attended, level of participation, quality of performance, and any transactions with the Company engaged in by such director during his term.

When selecting a new director nominee, the Committee first determines whether the nominee must be independent for Nasdaq purposes or whether the candidate must qualify as an “audit committee financial expert.” The Committee then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm to assist in the identification of qualified director candidates. The Committee also will consider nominees recommended by our stockholders. The Nominating and Governance Committee does not distinguish between nominees recommended by our stockholders and those recommended by other parties. The Committee evaluates the suitability of potential nominees, taking into account the current board composition, including expertise, diversity and the balance of inside and independent directors. The Nominating and Governance Committee endeavors to establish a diversity of background and experience in a number of areas of core competency, including business judgment, management, accounting, finance, knowledge of our industry, strategic vision, research and development and other areas relevant to our business.

In considering any person recommended by one of our stockholders, the Committee will look for the same qualifications that it looks for in any other person that it is considering for a position on the Board of Directors. The Nominating and Governance Committee operates under a formal charter that governs its duties and standards of performance. A copy of the charter is available on our website at www.heatbio.com.

Board Leadership Structure

Mr. Wolf, the Company’s Chief Executive Officer, also serves as Chairman of the Board of Directors. We have a separate, independent Lead Director. Although we do not have a formal policy addressing the topic, we believe that when the Chairman of the Board is an employee of the Company or otherwise not independent, it is important to have a separate Lead Director, who is an independent director.

Dr. Prendergast serves as the Lead Director. In that role, he presides over the Board’s executive sessions, during which our independent directors meet without management, and he serves as the principle liaison between management and the independent directors of the Board. The Lead Director also:

●

confers with the Chairman of the Board regarding Board meeting agenda;

●

chairs meetings of the independent directors including, where appropriate, setting the agenda and briefing the Chairman of the Board on issues discussed during the meeting;

●

oversees the annual performance evaluation of the CEO;

●

consults with the Nominating and Governance Committee and the Chairman of the Board regarding assignment of Board members to various committees; and

●

performs such other functions as the Board may require.

We believe the combination of Mr. Wolf as our Chairman of the Board and an independent director as our Lead Director is an effective structure for our company. The division of duties and the additional avenues of communication between the Board and our management associated with this structure provide the basis for the proper functioning of our Board and its oversight of management.

Risk Oversight

The Board has an active role, as a whole and also at the committee level, in overseeing management of our company’s risks. The Board regularly reviews information regarding our company’s strategy, finances and operations, as well as the risks associated with each. The Audit Committee is responsible for oversight of Company risks relating to accounting matters, financial reporting, internal controls and legal and regulatory compliance. The Audit Committee undertakes, at least annually, a review to evaluate these risks. The members then meet separately with management responsible for such area, including our Chief Financial Officer, and report to the Audit Committee on any matters identified during such discussions with management. In addition, the Compensation Committee considers risks related to the attraction and retention of talent as well as risks relating to the design of compensation programs and arrangements. In addition, the Nominating and Governance Committee manages risks associated with the independence of the Board. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is regularly informed through committee reports about such risks. The full Board considers strategic risks and opportunities and regularly receives detailed reports from the committees regarding risk oversight in their respective areas of responsibility.

Delinquent Section 16(a) Reports

Section 16(a) of the Securities Exchange Act of 1934 requires our executive officers, directors and persons who beneficially own more than 10 percent of a registered class of the Heat Biologics’ equity securities, to file with the SEC initial reports of ownership and reports of changes in ownership of our common stock. Such officers, directors and persons are required by SEC regulation to furnish us with copies of all Section 16(a) forms that they file with the SEC.

Based solely on a review of the copies of such forms that were received by us, or written representations from certain reporting persons that no Forms 5 were required for those persons, we are not aware of any failures to file reports or report transactions in a timely manner during the year ended December 31, 2020.

Code of Business Conduct and Ethics

We have long maintained a Code of Business Conduct and Ethics that is applicable to all of our directors, officers and employees. We undertake to provide a printed copy of these codes free of charge to any person who requests. Any such request should be sent to our principal executive offices attention: Corporate Secretary. The code is posted on our website at www.heatbio.com.

Item 11. Executive Compensation

We are a “smaller reporting company” and the following compensation disclosure is intended to comply with the requirements applicable to smaller reporting companies. Although the rules allow us to provide less detail about our executive compensation program, the Compensation Committee is committed to providing the information necessary to help stockholders understand its executive compensation-related decisions. Accordingly, this section includes supplemental narratives that describe the 2020 executive compensation program for our named executive officers.

Narrative Disclosure To Summary Compensation Table

Overview of Our Compensation Program

A. Philosophy and Objectives

Our primary objective with respect to executive compensation is to design compensation programs that will align executives’ compensation with our overall business strategies for the creation of stockholder value and attract, motivate and retain highly qualified executives.

Our executive compensation program is based on the following philosophies and objectives:

●

Compensation Should Align with Stockholders’ Interests — The Compensation Committee and our Board believes that executives’ interests should be aligned with those of the stockholders. Executives are granted restricted stock and stock options so that the majority of their total compensation is tied directly to the value realized by our stockholders. Executive bonuses are tied directly to company strategy and operational execution which contributed to our success as a whole.

Table of Contents

●

Compensation is Competitive — The Compensation Committee and Board seek to provide a total compensation package that attracts, motivates and retains the executive talent that we need in order to maximize the return to stockholders and execute our operational and scientific strategy. To accomplish this objective, executive compensation is reviewed annually to ensure that compensation levels are competitive and reasonable in relation to comparable companies with which we compete for talent.

●

Compensation Motivates and Rewards the Achievement of Goals — Our executive compensation program is designed to appropriately reward both individual and collective performance that meets and exceeds our annual and long-term strategic and operational goals. To accomplish this objective, a substantial percentage of total compensation is variable, “at risk”, both through annual incentive compensation and the granting of long-term incentive awards.

We seek to achieve these objectives through three key compensation elements:

●

a base salary;

●

a performance-based annual cash incentive (i.e., annual cash incentive compensation); and

●

long term equity awards.

In order to enhance the Compensation Committee’s ability to carry out its responsibilities effectively, as well as maintain strong links between executive pay and performance, the Compensation Committee reviews compensation information for each Named Executive Officer, which includes the following information:

●

Roles and Responsibilities of Compensation Committee

The primary purpose of the Compensation Committee is to conduct reviews of our general executive compensation policies and strategies and oversee and evaluate our overall compensation structure and programs. The Compensation Committee confirmed that total compensation paid to our Named Executive Officers during the year ended December 31, 2020, was reasonable and competitive. The following were our Named Executive Officers for the year ended December 31, 2020: Jeffrey Wolf, our Chief Executive Officer, William L. Ostrander, our Chief Financial Officer, and Jeff Hutchins, our former Chief Scientific Officer and former Chief Operating Officer (collectively, our “Named Executive Officers”). Responsibilities of the Compensation Committee include, but are not limited to:

●

Establishing on an annual basis performance goals and objectives for purposes of determining the compensation of our Chief Executive Officer and other senior executive officers, evaluating the performance of such officers in light of those goals and objectives, and setting the compensation level for those officers based on this evaluation.

●

Recommending to the Board the compensation for independent Board members (including retainer, committee and committee chair’s fees, stock options and components of compensation as appropriate).

●

Reviewing the competitive position of, and making recommendations to the Board with respect to, the cash-based and equity-based compensation plans and other programs relating to compensation and benefits.

Use of Compensation Consultant

The Compensation Committee retained Korn Ferry, a nationally-recognized global human resources consulting firm, as its independent compensation advisor in 2019. Korn Ferry principally provides analysis, advice and recommendations regarding named executive officer and non-employee director compensation as well as guidance and considerations on our long-term incentive program for all eligible employees including salary, bonus, benefits and equity awards for our executive officers and retainers, meeting fees and equity awards for our directors. The Compensation Committee retained Meridian Compensation Partners, LLC (“Meridian”), a nationally-recognized global human resources consulting firm, as its independent compensation advisor in 2020. Meridian principally provides analysis, advice and recommendations regarding named executive officer and non-employee director compensation as well as guidance and considerations on our long-term incentive program for all eligible employees including salary, bonus, benefits and equity awards for our executive officers and retainers, meeting fees and equity awards for our directors. Meridian reports to the Chairman of the Compensation Committee and has direct access to the other members of the Compensation Committee. Meridian does not provide any other services to the Company other than in its role as the Compensation Committee’s independent advisor. The Compensation Committee has evaluated Meridian’s reports and, as they considered appropriate to achieve the best interests of the Company and its stockholders, implemented the recommendations.

The Compensation Committee considered whether Meridian had any conflicts of interest in advising the Committee. In doing so, the Compensation Committee considered whether Meridian had been providing services of any other nature to us; the amount of fees received from us by Meridian; the policies and procedures adopted by Meridian that have been designed to prevent conflicts of interest; whether any business or personal relationships existed between the consultants employed by Meridian who worked on our matters and any member of the Compensation Committee; whether any business or personal relationship existed between such consultants and any of the our executive officers; and whether Meridian or such consultants hold any of our common stock. Upon evaluating such considerations, the Committee found no conflicts of interest in Meridian advising the Compensation Committee.

Role of the Chief Executive Officer

Our Chief Executive Officer, Mr. Wolf, makes recommendations to the Compensation Committee regarding the compensation of our other named executive officers. Mr. Wolf does not participate in any discussions or processes concerning his own compensation and participates in a non-voting capacity in discussions or processes concerning the compensation of our Chief Financial Officer and other members of management.

Compensation Committee Consideration of Shareholder Advisory Votes

At our annual meeting of stockholders held on July 23, 2019, we submitted our executive compensation program that covers our Named Executive Officers to our stockholders for a nonbinding advisory vote. Our executive compensation program received the support of holders of approximately 84% of the shares that voted on this proposal at the annual meeting of stockholders (including abstentions but excluding broker non-votes). In addition, at our annual meeting of stockholders held on July 23, 2019, our stockholders voted on an advisory basis with respect to the frequency of future advisory votes on our executive compensation program. Holders of a majority of the shares that voted on this proposal at

Table of Contents

the meeting (including abstentions but excluding broker non-votes) expressed their preference for an advisory vote every three years. Accordingly, we intend to hold an annual advisory vote on executive compensation at our annual meeting of stockholders in 2022.

C. Competitive Considerations

In making compensation decisions with respect to each element of compensation for our Named Executive Officers, the Compensation Committee believes that it is important to be informed as to the competitive market practices at similarly situated public companies. In setting 2020 target total direct compensation levels for our Named Executive Officers, the Compensation Committee relied in part on reports prepared by Korn Ferry in December 2019. In December 2019, Korn Ferry conducted a comprehensive assessment of our named executive officer pay program relative to a premier compensation survey which was specific to our size and industry at that time and a peer group of 18 similarly-situated public companies focused on oncology at a similar clinical development stage. The elements of the Named Executive Officer’s pay programs assessed against peer group practices for 2020 included the following compensation elements: (1) base salary, (2) target annual incentives (bonuses), (3) target total cash compensation, (4) long-term incentives and (5) target total direct compensation. In addition, Korn Ferry also provided an analysis of our pay mix and long-term incentive program relative to peer group practices. Korn Ferry’s assessment included our Chief Executive Officer, our Chief Financial Officer and our Chief Operating Officer/ Chief Scientific Officer. The Compensation Committee considered the competitive market pay data from both our publicly-traded peer group that was included in Korn Ferry’s analysis and relevant survey data which is specific to our size and industry. In setting 2021 target total direct compensation levels for our Named Executive Officers, the Compensation Committee relied in part on reports prepared by Meridian in December 2020. Meridian conducted a comprehensive assessment of our Named Executive Officer’s pay program relative to a peer group of 17 similarly-situated public companies that were pre-revenue cancer therapeutics companies with market capitalizations between $150 million and $1.5 billion. The elements of the Named Executive Officer’s pay programs assessed against peer group practices for 2021 included: (1) base salary, (2) target annual incentives (bonuses), (3) target total cash compensation, (4) long-term incentives and (5) target total direct compensation. In addition, Meridian also provided an analysis of our pay mix relative to peer group practices. Meridian’s assessment included our Chief Executive Officer and Chief Financial Officer. The Compensation Committee considered the competitive market pay data of our peer group that was included in Meridian’s analysis and relevant survey data when setting each Named Executive Officer’s compensation.

The Compensation Committee’s desired competitive positioning and its pay program decision-making (in terms of both compensation levels and overall mix of pay which is focused on variable or “at risk” compensation) is reflective of our pay for performance philosophy and provides alignment of executive interests with those of our stockholders.

We believe that, given the industry in which we operate and our compensation philosophy and objectives, our approach to executive compensation is sufficient to retain our current executive officers and to hire new executive officers when and as required.

D. Components of Compensation

The allocation between cash and non-cash named executive officer compensation is influenced by subjective and objective factors considered by the Compensation Committee and is intended to reflect the Compensation Committee’s determination of the appropriate compensation mix among base pay, annual cash incentives and long-term equity incentives for each named executive officers.

1. Base Salaries

We provide our Named Executive Officers a competitive level base salary commensurate with their position, responsibilities and experience. In setting the base salary, the Compensation Committee considers a number of factors including, peer group market data, our company performance and each Named Executive Officer’s role and

Table of Contents

responsibilities, experience and individual performance. We design base pay to be competitive in attracting and retaining top talent.

Initial base salaries for the Named Executive Officers were set by their initial respective employment contracts and are reviewed annually by the Compensation Committee. The Compensation Committee determined that our Chief Executive’s Officer’s and Chief Financial Officer’s 2020 base salary levels were below market practice of our peer group; therefore the base salaries were increased in January 2021. The 2020 and 2021 base salaries for our current Named Executive Officers are as follows:


Named Executive Officer	Base Salary 2019		Base Salary 2020		Base Salary 2021
Jeffrey Wolf, Chief Executive Officer	$	427,579	$	440,406	$	540,000
William L. Ostrander, Vice President of Finance	$	220,000	$	226,600	$	275,000

2. Bonuses

For 2020, the Compensation Committee recommended to the full Board of Directors the following bonus payouts to our Named Executive Officers:

●

Jeffrey Wolf bonus. The Board approved the Compensation Committee’s recommendation that Mr. Wolf receive a $220,203 cash bonus (50% of gross salary). In addition, in recognition of Mr. Wolf’s achievements in successfully financing our company and expanding the product development pipeline, the Board approved the Compensation Committee’s recommendation that Mr. Wolf also receive a $500,000 cash bonus in 2020 to cover his estimated taxes with respect to a restricted stock award that he received on January 4, 2020.

●

William Ostrander bonus. The Board approved the Compensation Committee’s recommendation that Mr. Ostrander receive a $45,321 cash bonus (20% of gross base salary).

The employment agreement with Jeffrey Wolf that was in effect during 2019 and 2020 provided that he was eligible for a cash performance bonus of up to fifty percent (50%) of his base as well an equity bonus in the sole discretion of the board of directors, with the actual amount of any such bonus increased or decreased in the sole discretion of the board of directors. William L. Ostrander’s offer letter that was in effect for 2020 provided for an annual bonus of up to twenty percent (20%) of his base and as well as an equity bonus in the sole discretion of the Board of Directors, with the actual amount of any such bonus increased or decreased in the sole discretion of the board of directors. The cash performance bonus was increased to thirty percent (30%) when he was promoted to Chief Financial Officer. The Compensation Committee believes that the granting of a bonus is appropriate to motivate the Named Executive Officers. The Compensation Committee focuses on individual performance, which enables the Compensation Committee to differentiate among executives and emphasize the link between personal performance and compensation. Although the Compensation Committee does not use any fixed formula in determining bonuses, it does link them to financial objectives of importance to it.

3. Long-Term Incentives

A substantial portion of the Named Executive Officer’s total compensation is in the form of equity-based compensation to encourage retention and better align the interests of the Named Executive Officers with the stockholders. The Compensation Committee determined to grant a combination of stock options and restricted stock awards to the current Named Executive Officers and other key employees as the primary long-term incentive vehicles.

In 2020 and 2021 the Compensation Committee determined the size of equity awards granted to the Named Executive Officers based on the following factors: accounting impact, peer group market data, our company performance and each Named Executive Officer’s position, role and responsibilities, experience, tenure, individual performance and pro forma percent ownership. In addition, the Compensation Committee considered that there was a lack of realizable value from their prior awards since substantially all of the prior awards were of significant low value and/or underwater or held low value. The Compensation Committee also sought to better align the Chief Executive Officer’s equity ownership interest in our company with that of other chief executive officers of our peer group companies. The Compensation Committee

Table of Contents

determined in January 2021 to grant a combination of options and restricted stock awards to the Chief Executive Officer and options to the Chief Financial Officer.

In December 2019, Jeffrey Wolf was granted 128,571 restricted stock awards as part of his long-term incentive compensation for the year ended December 31, 2020. In addition, Jeffrey Wolf was granted 282,857 restricted stock awards in January 2020. The restricted stock awards vest 50% immediately, 30% on the one-year anniversary of the grant date, 10% on the two-year anniversary grant date, and the remaining 10% on the three-year anniversary grant date. In January 2021, Jeffrey Wolf was granted 288,100 restricted stock awards as part of his long-term incentive compensation for the year ended January 2021. The restricted stock awards will vest 50% immediately and 50% on the one-year anniversary of the grant date. The restricted stock agreements with respect to the foregoing grants, among other things, prohibit transfers of the restricted stock prior to the two-year anniversary of the grant date other than by will, laws of descent and distribution and in the event of death. In addition, sales or transfers made after the two year anniversary of the grant date are subject to the right of us to buy back the stock at any time that the holder desires to sell the restricted stock at a price equal to the lower of the closing price per share and 32 times the closing price per share on the date of grant with respect to the 2019 and 2020 grants and 17 times the closing price per share on the date of grant with respect to the 2021 grants. In January 2021, Mr. Wolf was also granted an option to purchase up to 147,980 shares of common stock that vest on the two-year anniversary of the grant date.

In July and August 2020, Mr. Wolf was granted additional option awards to purchase 285,714 and 201,728 shares of common stock, respectively pursuant to the terms of his employment agreement entered into in 2009, which provided for such grant upon achievement of the milestone of our market capitalization being at least $500 million for at least 15 business days. These options vested upon issuance and are exercisable through the tenth anniversary of the date of grant.

Each of Jeffrey Wolf and, Jeff T. Hutchins, Ph.D. were also granted options to purchase 114,285 and 50,980 shares of common stock, respectively, in January 2019 as part of their annual long-term incentive compensation. In addition, Jeffrey Wolf and Jeff T. Hutchins, Ph.D. were issued 114,285 and 20,448 restricted stock awards, respectively in January 2019, as part of their annual long-term incentive compensation. The stock options and restricted stock awards granted vest 50% immediately, 30% on the one-year anniversary of the grant date, 10% shall vest on the two-year anniversary grant date, and the remaining 10% shall vest on the three-year anniversary grant date. The stock options have a term of ten years. Mr. Ostrander was granted an option to purchase 10,714 shares of common stock on September 25, 2019, upon his commencement of employment, that vests pro rata over four years. Pursuant to a separation agreement entered into between the Company and Dr. Hutchins on December 31, 2020, Dr. Hutchins stock options and restricted stock awards granted under the Company’s 2017 and 2018 Equity Incentive Plans ceased to continue to vest as of December 31, 2020 and were forfeited.

The Compensation Committee does not seek to time equity grants to take advantage of information, either positive or negative, about our company that has not been publicly disclosed. Option grants are effective on the date the award determination is made by the Compensation Committee, and the exercise price of options is the closing market price of our common stock on the business day of the grant or, if the grant is made on a weekend or holiday, on the prior business day.

Employment Agreements

On December 18, 2009, we entered into an employment agreement with Jeffrey Wolf to act as our Chief Executive Officer, which agreement was amended on November 22, 2011, and further amended on each of January 20, 2014, January 11, 2016, January 1, 2017 and January 2, 2020. Pursuant to the employment agreement in effect during 2020, Mr. Wolf received an annual base salary of $540,000 per year. He was also eligible to receive, at the sole discretion of the board, an additional cash performance-based bonuses equal to up to 50% of his then outstanding base salary at the end of each year and a discretionary equity award, with the actual amount of his bonus to be increased or decreased in the sole discretion of the Board of Directors.

On January 4, 2021, we entered into a new employment agreement with Jeffrey Wolf (the “Wolf Agreement”) to continue to serve as our Chief Executive Office and President, which agreement replaces the employment agreement that we had entered into with Mr. Wolf on December 18, 2009, as amended on November 22, 2011, and further amended on each of January 20, 2014, January 11, 2016, January 1, 2017 and January 2, 2020. Pursuant to the terms of the Wolf Agreement, Mr. Wolf will receive an annual base salary of $540,000 per year. He also may receive, at the sole discretion of the board, an additional cash performance-based bonuses equal to up to 50% of his then outstanding base salary at the end of each year and a discretionary equity award, with the actual amount of his bonus to be increased in the sole discretion of the Board of Directors.

In addition, subject to certain condition, Mr. Wolf may also be entitled to receive equity in newly formed subsidiaries of the Company. If the Wolf Agreement is terminated for death or disability (as defined in the Wolf Agreement), he (or his estate in the event of death) will receive any unpaid base salary through the date of death or disability, any unpaid target bonus earned through date of termination and he shall be entitled to exercise any vested awards for the shorter of 24 months after termination and the remaining term of the award. If Mr. Wolf’s employment is terminated by us other than for Cause (as defined in the agreement) or by him for Good Reason (as defined in the Wolf Agreement), he will receive a payment of an amount equal to one (1) times his annual base salary plus his annual target bonus amount for the year of termination assuming payment in full of the annual target bonus, accelerated vesting of all unvested equity awards, extension of the time period in which to exercise awards equal to the lesser of 24 months after termination or the remaining term of the award and payment of COBRA premiums for the earlier or twelve months, the date he becomes

Table of Contents

eligible for other group benefits or his rights to COBRA expire. In addition, in the event the Company terminates Mr. Wolf’s employment upon or at any time in connection with a Change of Control Transaction (as defined in the Wolf Agreement), Mr. Wolf is entitled to a lump sum cash payment equal to 24 months of his current base pay, a cash payment equal to a pro-rated amount of his target annual target bonus for the year preceding termination, payment in full for COBRA for 12 months following termination and immediate vesting of the unvested portion of any outstanding equity awards and a period to exercise the awards equal to the lesser of 12 months after termination or the remaining term of the award.

Under the Wolf Agreement, Mr. Wolf has also agreed to non-competition provisions.

Effective September 24, 2019 we entered into an offer letter with Mr. Ostrander to serve as our Vice President of Finance and Secretary. Effective January 4, 2021, Mr. Ostrander, was promoted to Chief Financial Officer. In connection with Mr. Ostrander’s new role as our Chief Financial Officer, effective January 4, 2021, we entered into an amendment (the “Ostrander Amendment”) to the offer letter, dated September 23, 2019, which had been amended on January 1, 2020. Pursuant to the Ostrander Amendment, Mr. Ostrander’s base salary has been increased from $226,600 to $275,000 and his bonus target has been increased to 30% of his base salary. Mr. Ostrander will also be eligible for other benefits consistent with those received by our other executives.

On January 2, 2017, we approved the entry for a four-year employment agreement, effective as of January 1, 2017, with Jeff T. Hutchins, Ph.D., which agreement was amended on June 29, 2017, January 1, 2018, January 1, 2019 and January 2, 2020 (collectively, the “Hutchins Employment Agreement”), who was initially appointed to serve as the Chief Scientific Officer and Senior Vice President of Pre-Clinical Development of the Company. Pursuant to the Hutchins Employment Agreement that was amended on June 29, 2017, Dr. Hutchins was appointed to serve as both Chief Scientific Officer and Chief Operating Officer.

The stock options are computed in accordance with FASB ASC 718 and reflect the value of an option to purchase 21,428 shares of common stock granted on January 2, 2020 to each individual board member with 50% vesting on grant date, 30% vesting on the one-year anniversary of the grant date and 10% vesting on the second and third year anniversaries of the grant date, subject to continued service as a board member through such date. The fair value of the options was calculated in accordance with FASB ASC 718, and the assumptions used are described in Note 11 to the Company's audited consolidated financial statements for the years ended December 31, 2020 and 2019.

(2)

Restricted stock awards are computed in accordance with FASB ASC 718 and reflect the aggregate grant date fair value of 57,142 shares granted on January 2, 2020 with 50% vesting on grant date, 30% vesting on the one-year anniversary of the grant date and 10% vesting on the second and third year anniversary of the grant date, subject to continued service as a board member through such date. The fair value of the restricted stock is based on the closing stock price of an unrestricted share of the Company's common stock on the grant date. As of December 31, 2020, the following table sets forth the number of aggregate outstanding option awards held by each of our directors who were not also named executive officers:

Our Compensation Committee conducted an evaluation of the compensation of the members of our board of directors with assistance from Korn Ferry for the compensation that was paid in 2020. During the year ended December 31, 2020, directors who were not employees received an annual cash fee of $35,000 as well as a cash fee of $8,000 for service on the Audit Committee and $5,000 for service on each of the Compensation Committee and the Nominating and Governance Committee. In addition, the Chairman of each of the Audit, Compensation and Nominating and Governance Committees will each receive an additional cash fee of $12,500, $8,500 and $7,000, respectively. The lead independent director received a monthly fee of $14,000 for his services as lead independent director.

Our Compensation Committee conducted an evaluation of the compensation of the members of our board of directors for 2021 with assistance from Meridian. Based on Meridian’s review, the Compensation Committee determined that the director pay program was consistent with competitive market practices (relative to Heat Biologic’s publicly traded peer group at that time), aligned with our overall philosophy and approach to director pay and reflective of desired competitive positioning. In January 2021 after consultation with Meridian, it was determined that directors who are not employees will receive an annual cash fee of $40,000 as well as a cash fee of $8,000 for service on the Audit Committee and $5,000 for service on each of the Compensation Committee and the Nominating and Governance Committee. In addition, the Chairman of each of the Audit, Compensation and Nominating and Governance Committees will each receive an additional cash fee of $12,500, $8,500 and $7,000, respectively. The lead independent director receives a monthly fee of $14,000 for his services as lead independent director.

The following stock option and awards are excluded from the above table. Due to the price of our common stock, it was determined that the equity portion of our director pay program was not consistent with competitive market practices (relative to our publicly traded peer group at that time). Accordingly, on January 4, 2021, after consultation with Meridian, Dr. Monahan and Mr. Smith received an option grant each to purchase 65,217 shares of our common stock vesting 100% on the grant date, which includes an annual grant and a one- time refresher grant. These stock option grants provided to Dr. Monahan and Mr. Smith will expire (10) years from the date of the grant, unless terminated earlier. For his services as lead independent director Dr. Prendergast received a grant of 138,272 restricted shares of common stock vesting 100% on the grant date, which includes an annual grant having a value of $85,000 and a one- time refresher grant. The restricted stock agreements with respect to the foregoing issuances of restricted stock, among other things, prohibit transfers of the restricted stock prior to the two-year anniversary of the grant date other than by will, laws of descent and distribution and in the event of death. In addition, sales or transfers made after the two- year anniversary of the grant date are subject to the right of us to buy back the stock at any time that the holder desires to sell the restricted stock at a price equal to the lower of the closing price per share and 17 times the closing price per share on the date of grant with respect to the 2021 grants.

Item 13. Certain Relationships and Related Transactions, and Director Independence

Pursuant to our charter, our Audit Committee shall review on an on-going basis for potential conflicts of interest, and approve if appropriate, all our “Related Party Transactions” as required by of Nasdaq Rule 4350(h). For purposes of the Audit Committee Charter, “Related Party Transactions” shall mean those transactions required to be disclosed pursuant to SEC Regulation S-K, Item 404.

The following is a summary of transactions since January 1, 2019 to which we have been a party in which the amount involved exceeded $120,000 and in which any of our executive officers, directors or beneficial holders of more than five percent of our capital stock had or will have a direct or indirect material interest, other than compensation arrangements which are described under the sections of this Annual Report entitled Part III, Item 10. “Directors, Executive Officers and Corporate Governance—2019 Director Compensation” and Part III, Item 11. “Executive Compensation:”

Table of Contents

Indemnification agreements

Our third amended and restated certificate of incorporation contains provisions limiting the liability of directors and our amended and restated bylaws provide that we will indemnify each of our directors to the fullest extent permitted under Delaware law. In addition, we have entered and expect to continue to enter into agreements to indemnify our directors.

Independence of the Board of Directors

The board of directors undertook a review of the independence of the members of the board of directors and considered whether any director has a material relationship with our company that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. Based upon information requested from and provided by each director concerning their background, employment and affiliations, including family relationships, the board of directors has determined that all of our current directors, except Mr. Wolf, due to his position as President and Chief Executive Officer of our company, is “independent” as that term is defined under the rules of Nasdaq. As a result, Dr. Monahan, Dr. Prendergast and Mr. Smith are deemed to be “independent” as that term is defined under the rules of Nasdaq. See the section of this Annual Report entitled “Item 10. Directors, Executive Officers and Corporate Governance.”

Item 14. Principal Accountant Fees and Services

Independent Registered Public Accounting Firm Fees and Services

The following table sets forth the aggregate fees including expenses billed to us for the years ended December 31, 2020 and 2019 by BDO USA, LLP.

(1)	Audit fees and expenses were for professional services rendered for the audit and reviews of the consolidated financial statements of the Company, professional services rendered for issuance of consents and assistance with review of documents filed with the SEC.

The Audit Committee has adopted procedures for pre-approving all audit and non-audit services provided by the independent registered public accounting firm, including the fees and terms of such services. These procedures include reviewing detailed back-up documentation for audit and permitted non-audit services. The documentation includes a description of, and a budgeted amount for, particular categories of non-audit services that are recurring in nature and therefore anticipated at the time that the budget is submitted. Audit Committee approval is required to exceed the pre-approved amount for a particular category of non-audit services and to engage the independent registered public accounting firm for any non-audit services not included in those pre-approved amounts. For both types of pre-approval, the Audit Committee considers whether such services are consistent with the rules on auditor independence promulgated by the SEC and the PCAOB. The Audit Committee also considers whether the independent registered public accounting firm is best positioned to provide the most effective and efficient service, based on such reasons as the auditor’s familiarity with our business, people, culture, accounting systems, risk profile, and whether the services enhance our ability to manage or control risks, and improve audit quality. The Audit Committee may form and delegate pre-approval authority to subcommittees consisting of one or more members of the Audit Committee, and such subcommittees must report any pre-approval decisions to the Audit Committee at its next scheduled meeting. All of the services provided by the independent registered public accounting firm were pre-approved by the Audit Committee.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Shareholders and Board of Directors

Heat Biologics, Inc.

Morrisville, North Carolina

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Heat Biologics, Inc. (the “Company”) as of December 31, 2020 and 2019, the related consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows for the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2020 and 2019, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

Warrant Accounting and Valuation

As described in Notes 2 and 11 to the Company’s consolidated financial statements, on January 21, 2020, the Company issued warrants to purchase 10,000,000 shares of the Company’s common stock in a public offering (the “new warrants”). Additionally, 479,595 previously issued and outstanding warrants that were previously classified as equity (the “prior warrants”) were evaluated whether they were modified for accounting purposes. Pursuant to the terms of the warrants, the warrants are not considered indexed to the Company’s own stock and therefore are required to be measured at fair value and reported as a liability on the consolidated balance sheets. The new and prior warrants were valued at approximately $2.5 million and $0.9 million, respectively, on the offering date, based on a Monte Carlo valuation methodology.

We identified the determination of the appropriate accounting treatment of the new and prior warrants and related valuation of the warrant liability as a critical audit matter due to the complexity associated with the analysis of whether the warrants are indexed to the Company’s own stock. Additionally, the valuation of the warrant liability involved the use of a complex valuation methodology that required management to make certain assumptions, including estimating stock price volatility for the remaining term. Auditing these

elements involved especially challenging and complex auditor judgment due to the nature and extent of auditor effort required, including the involvement of professionals with specialized skills and expertise.

The primary procedures we performed to address this critical audit matter included:

•

Utilizing personnel with specialized knowledge and experience in technical accounting to assist in (i) evaluating management’s interpretation of relevant terms and conditions of the warrant agreements, and (ii) evaluating management’s application of authoritative accounting guidance.

•

Utilizing professionals with specialized skills in valuation to assist in evaluating the reasonableness of the Company’s estimated fair value of the warrant liability by (i) comparing the Company’s estimate of volatility to our independently-developed estimate using historical stock price volatility information, and (ii) comparing the Company’s estimated fair value of the warrants to our independently-developed estimate utilizing a Monte Carlo methodology.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization

Heat Biologics is a biopharmaceutical company primarily engaged in the development of immune therapies and vaccines. Our gp96 platform is designed to activate the immune system. This platform has broad applications in cancer and infectious disease. The Company platform leverages gp96’s role as a natural molecular warning system that presents antigens to the immune system. HS-110 (viagenpumatucel-L) is the Company’s first allogeneic (“off-the-shelf”) cell line biologic product candidate in a series of proprietary immunotherapies designed to stimulate a patient’s T-cells to destroy cancer. HS-130 is an allogeneic cell line engineered to express the extracellular domain of OX40 ligand fusion protein (OX40L-Fc), a key costimulator of T-cells, with the potential to augment antigen-specific CD4+ T-cell and CD8+ T-cell responses. We have initiated development of a new COVID-19 vaccine program under our Zolovax, Inc. subsidiary that utilizes our gp96 platform to secrete SARS-CoV-2 antigens. The Company’s subsidiary Pelican Therapeutics, Inc. (“Pelican”), is developing PTX-35, a novel T-cell co-stimulator agonist antibody targeting TNFRSF25 for systemic administration.

These programs are designed to harness the body's natural antigen specific immune activation and tolerance mechanisms to reprogram immunity and provide a long-term, durable clinical effect. The Company has completed recruiting patients in its Phase 2 HS-110 non-small cell lung cancer (NSCLC) trial, dosed twelve patients in our Phase 1 clinical trial of HS-130 and dosed five patients in our Phase 1 clinical trial of PTX-35. The Company is also providing pre-clinical, CMC development, and administrative support for these operations; while constantly focusing on protecting and expanding our intellectual property in areas of strategic interest. As the Company advances its clinical programs, it is in close contact with the CROs and clinical sites and are assessing the impact of COVID-19 on the studies and current timelines and costs.

Unless otherwise noted, all share and per share data referenced in the consolidated financial statements and the notes thereto have been retroactively adjusted to reflect the one-for-seven reverse stock split effective December 11, 2020. As a result of the reverse stock split, certain amounts in the consolidated financial statements and the notes thereto may be slightly different than previously reported due to rounding of fractional shares, and certain amounts within the consolidated balance sheets were reclassified between common stock and additional paid-in capital.

2. Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of Heat Biologics, Inc. and its subsidiaries, Heat Biologics, Inc. (“the Company”), and its subsidiaries, Pelican Therapeutics, Inc. (“Pelican”), Heat Biologics I, Inc. (“Heat I”), Heat Biologics III, Inc. (“Heat III”), Heat Biologics IV, Inc. (“Heat IV”), Heat Biologics GmbH, Heat Biologics Australia Pty Ltd., Zolovax, Inc., Skunkworx Bio, Inc. (formerly known as Delphi Therapeutics, Inc.), and Scorpion Biosciences, Inc. As of December 31, 2020, there was no activity for Scorpion Biosciences, Inc. The functional currency of the entities located outside the United States of America (the foreign entities) is the applicable local currency of the foreign entities. Assets and liabilities of the foreign entities are translated at period-end exchange rates. Statement of operations accounts are translated at the average exchange rate during the period. The effects of foreign currency translation adjustments are included in other comprehensive loss, which is a component of accumulated other comprehensive loss in stockholders’ equity. All significant intercompany accounts and transactions have been eliminated in consolidation. The December 31, 2020 and 2019 year-end financials include 85% controlling interest in Pelican. Heat accounts for its less than 100% interest in the consolidated financial statements in accordance with U.S. GAAP. Accordingly, the Company presents non-controlling interest as a component of stockholders’ equity on its consolidated balance sheets and reports non-controlling interest net loss under the heading “net loss – non-controlling interest” in the consolidated statements of operations and comprehensive loss.

Liquidity and Capital Resources

The Company has an accumulated deficit of $130.6 million as of December 31, 2020 and a net loss of approximately $26.4 million for the year ended December 31, 2020 and has not generated significant revenue or positive cash flows from operations. The Company expects to incur significant expenses and continued losses from operations for the foreseeable

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

future. The Company expects its expenses to increase in connection with its ongoing activities, particularly as the Company continues its research and development and advances its clinical trials of, and seeks marketing approval for, its product candidates. In addition, if the Company obtains marketing approval for any of its product candidates, the Company expects to incur significant commercialization expenses related to product sales, marketing, manufacturing and distribution. Accordingly, the Company will need to obtain substantial additional funding in connection with its continuing operations. Adequate additional financing may not be available to the Company on acceptable terms, or at all. If the Company is unable to raise capital when needed or on attractive terms, it would be forced to delay, reduce or eliminate its research and development programs or any future commercialization efforts. To meet its capital needs, the Company intends to continue to consider multiple alternatives, including, but not limited to, additional equity financings such as sales of its common stock under at-the-market offerings, if available, debt financings, partnerships, collaborations and other funding transactions. On April 23, 2020, the Company filed a shelf registration statement on Form S-3 (the "Registration Statement"). Pursuant to the Registration Statement, the Company may offer and sell securities having an aggregate public offering price of up to $150 million. In connection with the filing of the Registration Statement, the Company also entered into an amendment to its sales agreement (“Common Stock Sales Agreement”) with B. Riley FBR, as sales agent, pursuant to which the Company may issue and sell shares of its common stock under an at-the-market (the “ATM”) offering program. On August 24, 2020, the Company amended and restated the Common Stock Sales Agreement (the “Amended and Restated Common Stock Sales Agreement”) to include Cantor Fitzgerald & Co. (“Cantor”) as an additional sales agent for the ATM. Pursuant to the ATM, the Company will pay B. Riley FBR or Cantor (each a “Designated agent” and collectively, the “Agents”), a commission rate of up to 3.0% of the gross proceeds from the sale of any shares of common stock. As of December 31, 2020, the Company had approximately $111.8 million in cash and cash equivalents and short-term investments, which it believes is sufficient to fund its operations for at least one year from the date these consolidated financial statements were issued. This is based on the Company’s current estimates, and the Company could use its available capital resources sooner than it currently expects. The Company is continually evaluating various cost-saving measures considering its cash requirements in order to focus resources on its product candidates. The Company will need to generate significant revenues to achieve profitability, and it may never do so.

Risk and Uncertainties

The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but are not limited to, uncertainty of results of clinical trials and reaching milestones, uncertainty of regulatory approval of the Company’s potential drug candidates, uncertainty of market acceptance of the Company’s products, competition from substitute products and larger companies, securing and protecting proprietary technology, strategic relationships and dependence on key individuals and sole source suppliers.

In March 2020, the World Health Organization declared COVID-19 a global pandemic. This contagious disease outbreak, which has continued to spread, and any related adverse public health developments, has adversely affected workforces, economies, and financial markets globally, potentially leading to an economic downturn. It has also disrupted the normal operations of many businesses. With the global spread of the ongoing COVID-19 pandemic, the Company has implemented business continuity plans designed to address and mitigate the impact of the COVID-19 pandemic on its business. The extent to which the COVID-19 pandemic impacts the Company’s business, the clinical development of the Company’s products, the business of the Company’s suppliers and other commercial partners, the Company’s corporate development objectives and the value of and market for the Company’s common stock, will depend on future developments that are highly uncertain and cannot be predicted with confidence at this time, such as the ultimate duration of the pandemic, travel restrictions, quarantines, social distancing and business closure requirements in the United States, Europe and other countries, and the effectiveness of actions taken globally to contain and treat the disease. The Company’s in human phase 1 trial of HS-130 was subject to an approximate 8 week enrollment pause in April and May 2020 due to lack of personal protection equipment (“PPE”) at a clinical site. The site ceased all non-critical/non-essential patient procedures until PPE supplies were available. Enrollment resumed and no delays in overall development milestones are expected for HS-130.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

With the global spread of the ongoing novel coronavirus (“COVID-19”) pandemic, the Company has implemented business continuity plans designed to address and mitigate the impact of the COVID-19 pandemic on its employees and business. While the Company is experiencing limited financial impacts at this time, given the global economic slowdown, the overall disruption of global healthcare systems and the other risks and uncertainties associated with the pandemic could have a material adverse effect on our business, financial condition, results of operations and growth prospects. In addition, to the extent the ongoing COVID-19 pandemic adversely affects the Company’s business and results of operations, it may also have the effect of heightening many of the other risks and uncertainties which the Company faces.

The Company relies on third-party manufacturers to purchase from their third-party vendors the materials necessary to produce product candidates and manufacture product candidates for clinical studies. The Company also depends on third-party suppliers for key materials and services used in research and development, as well as manufacturing processes, and are subject to certain risks related to the loss of these third-party suppliers or their inability to supply adequate materials and services. The Company does not control the manufacturing processes of the contract development and manufacturing organizations, or CDMOs, with whom it contracts and is dependent on these third parties for the production of its therapeutic candidates in accordance with relevant regulations (such as current Good Manufacturing Practices, or cGMP, which includes, among other things, quality control, quality assurance and the maintenance of records and documentation.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Estimates are used for, but not limited to, useful lives of fixed assets, contingent consideration, valuation of goodwill and in process research and development (“IPR&D”), income taxes, valuation of warrant liabilities, and stock-based compensation. Actual results may differ from those estimates.

Reclassifications

Certain prior year amounts have been reclassified to conform to the current year presentation in the consolidated financial statements and accompanying notes to the consolidated financial statements including the related party contingent consideration payable, which is now presented as a separate line item on the Company's consolidated balance sheets.

Segments

The Company has one reportable segment – the development of immunotherapies designed to activate and expand a patient’s T-cell mediated immune system against cancer.

Cash and Cash Equivalents

The Company considers all cash and other highly liquid investments with initial maturities from the date of purchase of three months or less to be cash and cash equivalents.

Short-term Investments

The Company’s short-term investments consist of equity securities and are carried at fair value. Unrealized gains and losses on securities are reported in the statement of operations. The Company classifies marketable equity investments available to fund current operations as current assets on its consolidated balance sheets.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Derivative Financial Instruments

The Company has issued common stock warrants in connection with the execution of certain equity financings. The fair value of the warrants, which were deemed to be derivative instruments, was recorded as a derivative liability under the provisions of ASC Topic 815 Derivatives and Hedging (“ASC 815”) because they are not considered indexed to the Company’s own stock. Subsequently, the liability is adjusted to fair value as of the end of each reporting period and the changes in fair value of derivative liabilities are recorded in the consolidated statements of operations and comprehensive loss under the caption “Change in fair value of warrant liability.”

The fair value of the warrants, including the warrants issued in connection with the January 2020 common stock offering and recorded as liability, was determined using the Monte Carlo simulation model, deemed to be an appropriate model due to the terms of the warrants issued.

The fair value of warrants was affected by changes in inputs to the Monte Carlo simulation model including the Company’s stock price, expected stock price volatility, the remaining term, and the risk-free interest rate. At December 31, 2020, the fair value of such warrants was $33,779, which is classified as a long-term derivative warrant liability on the Company’s consolidated balance sheets.

Concentration of Credit Risk

At times, cash balances may exceed the Federal Deposit Insurance Corporation (“FDIC”) insurable limits. The Company has never experienced any losses related to these balances. As of December 31, 2020, and 2019, cash amounts in excess of $250,000 were not fully insured. The uninsured cash balance as of December 31, 2020 was $10,367,714. The Company does not believe it is exposed to significant credit risk on cash and cash equivalents.

Property and Equipment

Property and equipment are stated at cost and are capitalized. Depreciation is calculated using the straight-line method and is based on estimated useful lives of five years for lab equipment, three years for computer equipment, eight years for furniture and fixtures and five years for leasehold improvements.

Net Loss per Share

Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during each year. Fully diluted net loss per share is computed using the weighted average number of common shares and dilutive securities outstanding during each year. Dilutive securities having an anti-dilutive effect on diluted loss per share are excluded from the calculation.

Fair Value of Financial Instruments

The carrying amount of certain of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued expenses and other payables approximate fair value due to their short maturities.

As a basis for determining the fair value of certain of the Company’s financial instruments, the Company utilizes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level I – Observable inputs such as quoted prices in active markets for identical assets or liabilities.

Level II – Observable inputs, other than Level I prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

F-11

Table of Contents

HEAT BIOLOGICS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Level III – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the entire fair value measurement requires management to make judgments and consider factors specific to the asset or liability. The Company’s cash equivalents are classified within Level I of the fair value hierarchy.

As of December 31, 2020, and December 31, 2019, the fair values of cash, accounts payable, and accrued expenses approximated their carrying values because of the short-term nature of these assets or liabilities. The Company’s short-term investments consist of Level I securities which are comprised of highly liquid money market funds. The estimated fair value of the short-term investments was based on quoted market prices. There were no transfers between fair value hierarchy levels during the years ended December 31, 2020 or 2019.

In January 2020, the Company issued warrants in connection with the public offering of common stock (the “January 2020 Warrants”). Pursuant to the terms of these warrants, the warrants were not considered indexed to the Company’s own stock and therefore are required to be measured at fair value and reported as a liability in the consolidated balance sheets. Additionally, upon the closing of the January 2020 offering, 479,595 outstanding warrants were evaluated whether they were modified for accounting purpose and were determined that they were required to be classified as a liability. The fair value of the warrant liability is based on the Monte Carlo methodology. The Company is required to revalue the warrants at each reporting date with any changes in fair value recorded on our consolidated statement of operations and comprehensive loss. The valuation of the warrants is classified under Level 3 of the fair value hierarchy due to the need to use assumptions in the valuation that are both significant to the fair value measurement and unobservable. In order to calculate the fair value of the warrants, certain assumptions were made, including the selling price or fair market value of the underlying common stock, risk-free interest rate, volatility, and remaining life. Changes to the assumptions could cause significant adjustments to valuation. The Company estimated a volatility factor utilizing its own data. The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of the grant for treasury securities of similar maturity.

The Monte Carlo simulation was used to value the liability-classified warrants, including the warrants reclassified from equity to liability. The following weighted average assumptions were used:


	January 21, 2020
Current stock price	$	2.31
Estimated volatility of future stock price		124	%
Risk free interest rate		1.53	%
Expected term		3.7	years

During the year ended December 31, 2020, 470,238 warrants were exchanged for 319,756 shares of common stock. As of December 31, 2020, there were a total of 9,357 warrants outstanding that were reported as a liability on the consolidated balance sheet.

The fair value of financial instruments measured on a recurring basis is as follows:

The change in the fair value of the contingent consideration of $1,199,000 and $613,290 for the years ended December 31, 2020 and 2019, respectively, was primarily due to the effect of the change in discount rate, probability of achieving milestones, and passage of time on the fair value measurement. Adjustments associated with the change in fair value of contingent consideration are included in the Company’s consolidated statement of operations and comprehensive loss.

The Company measures certain non-financial assets on a non-recurring basis, including goodwill and in-process R&D. As a result of those measurements, during the year ended December 31, 2019, goodwill with a total carrying value of $2.2 million was written down to its estimated fair value of $1.5 million and an impairment charge of $0.7 million was recorded. The Company uses a present value technique to estimate the fair value of these assets. This analysis requires significant judgments, including primarily the estimation of future development costs, the probability of success in various phases of its development programs, potential post-launch cash flows and a risk-adjusted weighted average cost of capital.

Income Tax

Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of assets and liabilities and their respective tax bases, operating loss carryforwards, and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

In accordance with FASB ASC 740, Accounting for Income Taxes, the Company reflects in the financial statements the benefit of positions taken in a previously filed tax return or expected to be taken in a future tax return only when it is considered ‘more-likely-than-not’ that the position taken will be sustained by a taxing authority. As of December 31, 2020 and 2019, the Company had no unrecognized income tax benefits and correspondingly there is no impact on the Company’s effective income tax rate associated with these items. The Company’s policy for recording interest and penalties relating to uncertain income tax positions is to record them as a component of income tax expense in the accompanying consolidated statements of operations. As of December 31, 2020 and 2019, the Company had no such accruals.

Stock-Based Compensation

The Company accounts for stock-based compensation arrangements with employees and non-employee directors using a fair value method that requires the recognition of compensation expense for costs related to all stock-based payments, including stock options and restricted stock units. The fair value method requires the Company to estimate the fair value of stock-based payment awards on the date of grant using an option pricing model. The fair value of restricted stock units is estimated based on the closing price of the Company’s stock on the date of grant, and for the purposes of expense recognition, the total new number of shares expected to vest is adjusted for estimated forfeitures.

Stock-based compensation costs are based on the fair value of the underlying option calculated using the Black-Scholes-Merton option pricing model on the date of grant for stock options and are recognized as expense on a straight-line basis over the requisite service period, which is the vesting period. Determining the appropriate fair value model and related assumptions requires judgment, including estimating stock price volatility, forfeiture rates and expected term. The expected volatility rates are estimated based on average historical stock price volatility of its own data plus an analysis of reported data for a peer group of comparable companies that have issued stock options with substantially similar terms. The expected term for the years ended December 31, 2020 and 2019 represents the average time that options are expected to be outstanding based on the average of the vesting term and the contractual term of the option. We account for forfeitures as they occur. The Company has not paid dividends and does not anticipate paying a cash dividend in the foreseeable

future and, accordingly, uses an expected dividend yield of zero. The risk-free interest rate is based on the rate of U.S. Treasury securities with maturities consistent with the estimated expected term of the awards.

Net loss attributable to non-controlling interests

Net loss attributable to non-controlling interests is the result of the Company’s consolidation of subsidiaries of which it does not own 100%. In October 2018, the Company entered into an agreement with the University of Miami (“UM”) whereby UM exchanged its shares of stock in the Company’s subsidiaries, Heat I, Inc. and Pelican, a related party prior to acquisition, for 35,000 shares of the Company’s common stock. The stock exchange resulted in the Company owning 100% of Heat I, Inc. and increasing its controlling ownership in Pelican from 80% to 85%. The Company’s net loss attributable to non-controlling interests relates to the 15% ownership of Pelican that Heat does not own as of December 31, 2020 and 2019.

Revenue Recognition

Effective January 1, 2019, the Company has adopted ASU No. 2018-08, Not-For-Profit Entities (Topic 958): Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made. The Company’s primary source of revenue is grant revenue related to the CPRIT contract, which is being accounted for under ASC 958 as a conditional non-exchange contribution.

The CPRIT grant covers the periods from June 1, 2017 through May 31, 2021, for a total grant award of up to $15.2 million. CPRIT advances grant funds upon request by the Company consistent with the agreed upon amounts and schedules as provided in the contract. The first tranche of funding of $1.8 million was received in May 2017, and a second tranche of funding of $6.5 million was received in October 2017, and the third tranche of funding of $5.4 million was received in December 2019. The remaining $1.5 million will be awarded, on a reimbursement basis, after we have fulfilled every requirement of the grant and the grant has been approved to be finalized. Funds received are reflected in deferred revenue as a liability until revenue is earned. Grant revenue is recognized when qualifying costs are incurred. As of December 31, 2020, the deferred revenue balance was $0.6 million with $13.1 million recognized as revenue since contract inception.

On January 7, 2020, the Company was awarded a grant of up to $224,713 from the NIH. The NIH grant provides funding for continued development of the Company’s technologies for PTX-35. The grant funds will be made available by the NIH to the Company as allowable expenses are incurred. For the year ended December 31, 2020, the Company incurred approximately $0.1 million of allowable expenses under the NIH grant and recognized a corresponding amount of grant revenues.

Business Combinations

We account for acquisitions using the acquisition method of accounting, which requires that all identifiable assets acquired and liabilities assumed be recorded at their estimated fair values. The excess of the fair value of purchase consideration over the fair values of identifiable assets and liabilities is recorded as goodwill. When determining the fair values of assets acquired and liabilities assumed, management makes significant estimates and assumptions. Critical estimates in valuing certain intangible assets include but are not limited to future expected cash flows from acquired patented technology. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. Other estimates associated with the accounting for acquisitions may change as additional information becomes available regarding the assets acquired and liabilities assumed (see Note 4).

Goodwill and In-Process Research and Development

The Company classifies intangible assets into three categories: (1) intangible assets with definite lives subject to amortization, (2) intangible assets with indefinite lives not subject to amortization and (3) goodwill. The Company determines the useful lives of definite-lived intangible assets after considering specific facts and circumstances related to each intangible asset. Factors the Company considers when determining useful lives include the contractual term of any agreement related to the asset, the historical performance of the asset, and other economic facts; including competition and specific market conditions. Intangible assets that are deemed to have definite lives are amortized, primarily on a straight-line basis, over their estimated useful lives. Intangible assets that are deemed to have indefinite lives, including goodwill, are reviewed for impairment annually, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test for indefinite-lived intangibles, other than goodwill, consists of a comparison of the fair value of the intangible asset with its carrying amount. If the carrying amount exceeds the fair value, an impairment charge is recognized in an amount equal to that excess. Indefinite-lived intangible assets, such as goodwill, are not amortized. The Company tests the carrying amounts of goodwill for recoverability on an annual basis or when events or changes in circumstances indicate a potential impairment exists, using a fair value-based test. Pursuant to ASU 2017-04, the Company must record a goodwill impairment charge if a reporting unit’s carrying value exceeds its fair value. See Note 7 regarding impairment at December 31, 2019.

IPR&D, assets are considered to be indefinite-lived until the completion or abandonment of the associated research and development projects. IPR&D assets represent the fair value assigned to technologies that the Company acquires, which at the time of acquisition have not reached technological feasibility and have no alternative future use. During the period that the assets are considered indefinite-lived, they are tested for impairment on an annual basis, or more frequently if the Company becomes aware of any events occurring or changes in circumstances that indicate that the fair value of the IPR&D assets are less than their carrying amounts. If and when development is complete, which generally occurs upon regulatory approval and the ability to commercialize products associated with the IPR&D assets, these assets are then deemed definite-lived and are amortized based on their estimated useful lives at that point in time. If development is terminated or abandoned, the Company may have a full or partial impairment charge related to the IPR&D assets, calculated as the excess of carrying value of the IPR&D assets over fair value.

Deferred Revenue

Contingent Consideration

Consideration paid in a business combination may include potential future payments that are contingent upon the acquired business achieving certain milestones in the future (“contingent consideration”). Contingent consideration liabilities are measured at their estimated fair value as of the date of acquisition, with subsequent changes in fair value recorded in the consolidated statements of operations and comprehensive loss. The Company estimates the fair value of the contingent consideration as of the acquisition date using the estimated future cash outflows based on the probability of meeting future milestones. The milestone payments will be made upon the achievement of clinical and commercialization milestones as well as single low digit royalty payments and payments upon receipt of sublicensing income. Subsequent to the date of acquisition, the Company reassess the actual consideration earned and the probability-weighted future earn-out payments

at each balance sheet date. Any adjustment to the contingent consideration liability will be recorded in the consolidated statements of operations. Contingent consideration liabilities expected to be settled within 12 months after the balance sheet date are presented in current liabilities, with the non-current portion recorded under long term liabilities in the consolidated balance sheets (see Note 4).

Research and Development

Research and development costs associated with developmental products not yet approved by the FDA as well as costs associated with bringing developmental products into advanced phase clinical trials are expensed as incurred. These costs consist primarily of pre-manufacturing and manufacturing drug costs, clinical trial execution, investigator payments, license fees, salaries, stock-based compensation and related personnel costs. Other costs include fees paid to consultants and outside service providers related to the development of the Company’s product candidates and other expenses relating to the design, development, and testing and enhancement of its product candidates.

3. Short-Term Investments

Short-term investments consist of equity securities with a maturity of greater than three months when acquired. The Company holds its securities at fair value as of December 31, 2020 and 2019. Unrealized gains and losses on securities are reported in the statement of operation. Short-term investments at December 31, 2020 and 2019 consisted of mutual funds with fair values of $100.8 million and $5.7 million, respectively.

4. Acquisition of Pelican Therapeutics

In 2017, the Company consummated the acquisition of 80% of the outstanding equity of Pelican, a related party, and Pelican became a majority owned subsidiary of the Company. During the quarter ended March 31, 2018, cash consideration of approximately $300,000 was distributed to the participating Pelican stockholders and the remainder of approximately $200,000 for certain Pelican liabilities not satisfied was recognized as other income in the statements of operations and comprehensive loss for the period. In October 2018, Heat entered into an agreement with the University of Miami (“UM”) whereby UM exchanged its shares of stock in Heat’s subsidiaries, Heat I, Inc. and Pelican. The stock exchange resulted in Heat increasing its controlling ownership in Pelican from 80% to 85%.

Under the agreement, the Company is also obligated to make future payments based on the achievement of certain clinical and commercialization milestones, as well as low single digit royalty payments and payments upon receipt of sublicensing income.

●

$1.5 million upon Pelican’s dosing of the first patient in its first Phase 2 trial for an oncology indication;

●

$3.0 million upon successful outcome of the first Phase 2 trial for an oncology indication;

●

$6.0 million upon Pelican’s dosing of the first patient in its first Phase 3 trial for an oncology indication;

●

$3.0 million upon Pelican’s dosing of the first patient in its first Phase 3 trial for a non- oncology indication;

●

$7.5 million upon successful outcome of the first Phase 3 trial for an oncology indication;

●

$3.0 million upon successful outcome of the first Phase 3 trial for a non-oncology indication;

●

$7.5 million upon acceptance of a Biologics License Application (BLA) submission for an oncology indication;

●

$3.0 million upon acceptance of a BLA submission for a non-oncology indication;

●

$7.5 million upon first product indication approval in the United States or Europe for an oncology indication;

●

$3.0 million upon first product indication approval in the United States or Europe for a non-oncology indication.

The fair value of these future milestone payments is reflected in the contingent consideration account under current liabilities with the non-current portion under long term liabilities on the balance sheet. The estimated fair value of the contingent consideration was determined using a probability-weighted income approach. The Company estimates the fair value of the contingent consideration on a quarterly basis. At the time of the Pelican acquisition, the Company’s CEO and certain affiliated entities as well as two of the Company’s directors and certain affiliated entities directly or indirectly owned shares of Pelican common stock purchased by the Company. As a result, approximately 22.7% of any such milestone payments will be paid to certain directors of the Company which is presented separately on the balance sheet as contingent consideration, related party - net of current portion. On June 22, 2020, the Company achieved the first milestone of $2.0 million when it dosed the first patient in the first Phase 1 clinical trial of PTX-35.

Goodwill was calculated as the difference between the acquisition-date fair value of the consideration transferred and the fair values of the assets acquired and liabilities assumed. The goodwill resulting from this acquisition related largely to synergies expected from combining the operations. The goodwill is not deductible for income tax purposes. In-process research and development assets are treated as indefinite-lived until the completion or abandonment of the associated research and development (“R&D”) program, at which time the appropriate useful lives will be determined. The Company calculated the fair value of the non-controlling interest acquired in the acquisition as 20% of the equity interest of Pelican, adjusted for a minority interest discount.

As discussed in Note 10, in May 2016, Pelican was awarded a $15.2 million CPRIT Grant from CPRIT for development of Pelican’s lead product candidate, PTX-35. The CPRIT Grant is expected to support Pelican in developing PTX-35 through a Phase 1 clinical trial designed to evaluate PTX-35 in combination with other immunotherapies or as a monotherapy.

7. Goodwill and In-process R&D

Goodwill of $2.2 million and in-process R&D of $5.9 million were recorded in connection with the acquisition of Pelican, as described in Note 4. The Company performs an annual impairment test at the reporting unit level as of April 1st of each fiscal year. As of April 1, 2020, the Company qualitatively assessed whether it is more likely than not that the respective fair value of the reporting unit is less than its carrying amount, including goodwill. Based on that assessment, the Company determined that this condition does not exist. As such, performing the first step of the two-step test impairment test was unnecessary. No impairment was recorded during the year ended December 31, 2020.

However, during the year ended December 31, 2019, the Company experienced a sustained decline in the quoted market price of the Company’s common stock and as a result the Company determined that as of December 31, 2019 it was more likely than not that the carrying value of these acquired intangibles exceeded their estimated fair value. Accordingly, the Company performed an interim impairment analysis as of that date using the income approach. This analysis required significant judgments, including primarily the estimation of future development costs, the probability of success in various phases of its development programs, potential post-launch cash flows and a risk-adjusted weighted average cost of capital. Pursuant to ASU 2017 04, the Company recorded a goodwill impairment charge for the excess of the reporting unit’s

● University of Miami

●

Beginning in 2008, the Company has entered into various agreements with the University of Miami (“UM”) for intellectual and tangible property rights relating to the ImPACT^®, technology activities (“License Agreement 03-31, 05-39” and “License Agreement 97-14”, or collectively “License Agreements”). These license agreements were subsequently assigned to the Company’s subsidiary Heat Biologics I, Inc. (Heat I) which issued to UM shares of its common stock representing seven and one-half percent (7.5%) of its common stock. The term of the license is the length of the last to expire patent, unless terminated earlier.

●

The Company agreed to make minimum royalty payments of $10,000 for three years beginning in 2010 that are due on the anniversary date of the agreement for License Agreement 97-14. Beginning in 2013, and thereafter for the life of the agreement, the minimum royalty payment shall be $20,000 due on the same date. In July 2016, the Company and UM entered into an amendment which replaced the milestone payment of $250,000 by approval of a BLA for the lung cancer vaccine with a payment of $500,000 upon approval of an NDA for a lung cancer vaccine covered by Patent Rights.

●

In August 2009, Heat I and UM entered into a second amendment (“Amendment 2”) to License Agreement UMSS-114A to extend the foregoing payment due dates for all past due license fees and patent costs.

10. Grant Revenue

In June 2016, Pelican entered into a cancer research grant contract or Grant Contract with CPRIT, under which CPRIT awarded a grant not to exceed $15.2 million for use in developing cancer treatments by targeting a novel T-cell costimulatory receptor (namely, TNFRSF25). The Grant Contract initially covered a period from June 1, 2016 through November 30, 2019, as amended, was extended to May 30, 2021. The first tranche of funding of $1.8 million was received in May 2017, a second tranche of funding of $6.5 million was received in October 2017, and a third tranche of funding of $5.4 million was received in December 2019. The remaining $1.5 million will be awarded on a reimbursement basis after we have fulfilled every requirement of the grant and the grant has been approved to be finalized.

The grant is subject to customary CPRIT funding conditions including a matching funds requirement where Pelican will match $0.50 for every $1.00 from CPRIT. Consequently, Pelican is required to provide $7.6 million in matching funds over the life of the project. Upon commercialization of the product, the terms of the grant require Pelican to pay tiered royalties in the low to mid-single digit percentages. Such royalties reduce to less than one percent after a mid-single-digit multiple of the grant funds have been paid to CPRIT in royalties.

Through December 31, 2020, $13.1 million of grant funding received to date has been recognized as revenue.

There are 1,788,730 stock options remaining available for grant under the 2009 Plan, 2014 Plan, 2017 Plan and 2018 Plan (collectively, the “Plans”). The following table summarizes the components of the Company’s stock-based compensation included in net loss:


	For the years ended
	December 31,
	2020		2019
Employee stock options	$	4,966,596	$	1,349,089

Non-employee stock awards		179,792		325,521
	$	6,377,857	$	3,269,948

Accounting for Stock-Based Compensation:

Stock Compensation Expense - For the years ended December 31, 2020, and 2019, we recorded $6,377,857, and $3,269,948 of stock-based compensation expense, respectively. No compensation expense of employees with stock awards was capitalized during the years ended December 31, 2020 and 2019.

Stock Options - Under the Plans, we have issued stock options. A stock option granted gives the holder the right, but not the obligation to purchase a certain number of shares at a predetermined price for a specific period of time. We typically issue options that vest over four years in equal installments beginning on the first anniversary of the date of grant. Under the terms of the Plans, the contractual life of the option grants may not exceed ten years. During the years ended December 31, 2020, and 2019, we issued options that expire ten years from the date of grant.

Fair Value Determination - We have used the Black-Scholes-Merton option pricing model to determine fair value of our stock option awards on the date of grant. We will reconsider the use of the Black-Scholes-Merton model if additional information becomes available in the future that indicates another model would be more appropriate or if grants issued in future periods have characteristics that cannot be reasonably estimated under this model.

The following weighted-average assumptions were used for option grants during the years ended December 31, 2020 and 2019:

●

Volatility – The Company used an average historical stock price volatility of its own data plus an analysis of reported data for a peer group of comparable companies that have issued stock options with substantially similar terms.

●

Expected life of options – The expected term represents the period that the Company’s stock option grants are expected to be outstanding. The Company elected to utilize the “simplified” method to estimate the expected term. Under this approach, the weighted-average expected life is presumed to be the average of the vesting term and the contractual term of the option.

●

Risk-free interest rate – The rate is based on U.S. Treasury interest rates at the time of the grant whose term is consistent with the expected life of the stock options.

●

Dividend yield – The expected dividend yield was considered to be 0% in the option pricing formula since the Company had not paid any dividends and had no plan to do so in the future.

●

Forfeitures – As required by ASC 718, the Company reviews recent forfeitures and stock compensation expense. We account for forfeitures as they occur.

The following table summarizes assumptions used in our calculations of fair value for the years ended December 31, 2020 and 2019:


	2020		2019
Dividend yield	—	%	—	%
Expected volatility	83.13-101.68	%	89.59-91.03	%
Risk-free interest rate	0.26-1.69	%	1.63-2.52	%
Expected lives (years)	5.0-6.3	years	5.4-6.3	years

Stock Option Activity - The weighted-average grant date fair value of options granted during the years ended December 31, 2020 and 2019, as determined under the Black-Scholes valuation model, was $5.92 and $5.27, respectively.

The following table summarizes stock option activity for the years ended December 31, 2020 and 2019:

Stock options exercisable at December 31, 2020	871,721	$	14.74	$	120,993	8.1	Years

Unrecognized compensation expense related to unvested stock options was $2.4 million as of December 31, 2020, which is expected to be recognized over a weighted-average period of 1.75 years and will be adjusted for forfeitures as they occur.

Restricted Stock - Under the Plans, the Company has issued restricted stock. A restricted stock award is an issuance of shares that cannot be sold or transferred by the recipient until the vesting period lapses. Restricted stock issued to members of our Board of Directors and Executives vest 50% on grant date, 30% on the first anniversary and 10% each anniversary thereafter. The grant date fair value of the restricted stock is equal to the closing market price of the Company’s common stock on the date of grant.

RSUs - Under the Plans, the Company has time-based RSUs. RSUs are not actual shares, but rather a right to receive shares in the future. The shares are not issued and the employee cannot sell or transfer shares prior to vesting and has no voting rights until the RSUs vest. The employees' time-based RSUs will result in the delivery of shares in one-fourth increments commencing on the award date. The grant date fair value of the RSUs is equal to the closing market price of the Company’s common stock on the grant date. The Company recognizes the grant date fair value of RSUs of shares it expects to issue as compensation expense ratably over the requisite service period.

12. Income Tax

Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of assets and liabilities and their respective tax bases, operating loss carryforwards, and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

At December 31, 2020 and December 31, 2019, the Company evaluated all significant available positive and negative evidence, including the existence of losses in recent years and management’s forecast of future taxable income, and, as a result, determined it was more likely than not that federal and state deferred tax assets, including benefits related to net operating loss carryforwards, would not be realized. The valuation allowance was increased from $26,793,281 at December 31, 2019 to $32,484,566 at December 31, 2020. Net Operating Losses created in years beginning after 2017 now only offset 80% of Taxable Income but no longer have a 20 year expiration. As such, NOL’s created after 2017 can be used to offset indefinite lived liabilities up to 80%.

At December 31, 2020, the Company has federal net operating loss carryforwards of approximately $118,799,856, including $3,027,284 acquired from Pelican Therapeutics, which are available to offset future taxable income. However, due to potential Section 382 limitations (discussed in further detail below) a reserve has been set up for the Pelican Therapeutics NOL of $(2,416,776). The federal net operating loss carryforwards begin to expire in 2029. The Company has various state net operating loss carryforwards totaling approximately $103,538,617 including $2,464,819 from Pelican Therapeutics, which are available to offset future state taxable income. State net operating losses begin to expire in 2024. The Company has various foreign net operating loss carryforwards of approximately $127,610. The foreign net operating loss carryforwards are carried forward indefinitely. Because the Company has incurred cumulative net operating losses since inception, all tax years remain open to examination by U.S. federal, state, and foreign income tax authorities.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

In accordance with FASB ASC 740, Accounting for Income Taxes, the Company reflects in the financial statements the benefit of positions taken in a previously filed tax return or expected to be taken in a future tax return only when it is considered ‘more-likely-than-not’ that the position taken will be sustained by a taxing authority. As of December 31, 2020 and 2019, the Company had no unrecognized income tax benefits and correspondingly there is no impact on the Company’s effective income tax rate associated with these items. The Company’s policy for recording interest and penalties relating to uncertain income tax positions is to record them as a component of income tax expense in the accompanying statements of income. As of December 31, 2020 and 2019, the Company had no such accruals

The Company files income tax returns in the United States, various state and foreign jurisdictions. The Company is subject to examination by taxing authorities for the tax years ended December 31, 2009 through 2019.

Potential 382 Limitation

The Company’s ability to utilize its net operating loss (NOL) and research and development (R&D) credit carryforwards may be substantially limited due to ownership changes that may have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended (the Code), as well as similar state provisions. These ownership changes may limit the amount of NOL and R&D credit carryforwards that can be utilized annually to offset future taxable income and tax, respectively. In general, an “ownership change,” as defined by Section 382 of the Code, results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percent of the outstanding stock of a company by certain stockholders or public groups.

Due to the recent ownership changes, the Company is in the process of performing a study to determine whether a limitation of net operating losses and other attributes under IRC Sections 382 and 383 has occurred. The amount of NOL’s subject to this study are approximately $65 million. Since the study is still in-process, the deferred tax assets attributes subject to limitation are currently included in the consolidated financial statements, offset in full by a valuation allowance. When the section 382 study is complete, the limited deferred tax assets and related valuation allowances will be written off.

13. Leases

Effective January 1, 2019, the Company adopted ASC 842 using the optional transition method, applying no practical expedients. In accordance with the optional transition method, the Company did not recast the prior period consolidated financial statements. The lease term is the noncancelable period of the lease. There are no termination provisions or renewal periods reasonably certain of exercise or options controlled by the lessor. The Company has determined that its leases, consisting of leases for office and laboratory space without optional terms or variable components, are operating leases. Adoption of the new standard resulted in the recording of operating lease right-of-use assets and associated lease liabilities of $520,399 and $528,253, respectively, as of January 1, 2019 on the consolidated balance sheet with no cumulative impact to accumulated deficit and did not have a material impact on our results of operations or cash flows.

The Company conducts its operations from leased facilities in Morrisville, North Carolina, San Antonio, Texas and New Brunswick, New Jersey, the leases for which will expire in 2027, 2023 and 2022. The leases are for general office space and lab space and require the Company to pay property taxes, insurance, common area expenses and maintenance costs.

On October 1, 2019, commencement date of our Morrisville, North Carolina lease, a right-of-use asset of $2.0 million and a liability of $1.4 million were recorded on our balance sheet. Total cash paid for operating leases during the year ended December 31, 2020 and 2019 was $0.3 million and $0.7 million and is included within cash flows from operating activities within the consolidated statement of cash flows.

The Company leases furniture and specialized lab equipment under finance leases. The related right-of-use assets are amortized on a straight-line basis over the lesser of the lease term or the estimated useful life of the asset. The effective interest rate was 6.17% for the years ended December 31, 2020 and 2019.

14. Related Party Transactions

The Company compensates its board members. Board members received cash compensation between approximately $61,500 and $221,000, for services rendered during 2020 and 2019. Board members also received equity compensation.

The Company owns 85% of the outstanding equity of Pelican, a related party as of the year ended December 31, 2020. See Note 4 about future milestone payments that may be paid to Participating Pelican Shareholders.

15. Net Loss Per Share

Basic net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the periods. Fully diluted net loss per common share is computed using the weighted average number of common and dilutive common equivalent shares outstanding during the periods. Common equivalent shares consist of stock options and warrants that are computed using the treasury stock method.

For the years ended December 31, 2020 and 2019, all of the Company’s common stock options, unvested restricted stock units and warrants are anti-dilutive and therefore have been excluded from the diluted calculation.

The following table reconciles net loss to net loss attributable to Heat Biologics, Inc.:


	For the Years Ended
	December 31,
	2020		2019
Net loss	$	(26,381,389)	$	(20,384,716)
