Overview

We operate in four primary business areas: first, the application of artificial intelligence (“AI”) in our precision medicine business, to provide AI-driven predictive models of tumor drug response to improve clinical outcomes for patients and to assist pharmaceutical, diagnostic, and biotech industries in the development of new personalized drugs and diagnostics; second, creation and development of tumor-specific 3D cell culture models driving accurate prediction of clinical outcomes; third, contract services and research focused on solubility improvements, stability studies, and protein production, and;  fourth, production of the United States Food and Drug Administration (“FDA”)-cleared STREAMWAY® System for automated, direct-to-drain medical fluid disposal and associated products.

We have four reportable segments: Helomics®, zPREDICTA®, Soluble^TM and Skyline®. The Helomics segment includes clinical testing and contract research services that include the application of AI. Our zPREDICTA, Inc. (“zPREDICTA”) segment, which was effective upon the closing of the acquisition of zPREDICTA on November 24, 2021, specializes in organ-specific disease models that provide 3D reconstruction of human tissues accurately representing each disease state and mimicking drug response enabling accurate testing of anticancer agents. Our Soluble segment provides services using a self-contained, automated system that conducts high-throughput, self-interaction chromatography screens, using additives and excipients commonly included in protein formulations resulting in soluble and physically stable formulations for biologics. Our Skyline segment consists of the STREAMWAY System product sales, and our TumorGenesis® subsidiary (Research and Development) is included within corporate. Going forward, we have determined that we will focus our resources on the Helomics and zPREDICTA segments and our primary mission statements to accelerate patient-centric drug discovery to improve patient outcomes in cancer treatment, harnessing the power of AI, and to develop tumor-specific 3D cell culture models that provide accurate 3D reconstruction of human tissues representing each cancer disease state.

On November 24, 2021, we acquired zPREDICTA in a merger transaction, and at that time we identified zPREDICTA as a reportable segment. zPREDICTA’s business, which involves integration of organ-specific cellular and extracellular elements into 3D cell culture models for in vitro cancer drug testing, represents a unique segment in the Predictive offerings.

HELOMICS

Our precision medicine business, conducted in our Helomics division, is committed to improving the effectiveness of cancer therapy using our proprietary, multi-omic tumor profiling platform, a one-of-a-kind database of historical tumor data, and the power of AI to build predictive models of tumor drug response.

4

Helomics’ mission is to improve clinical outcomes for patients by partnering with pharmaceutical, diagnostic, and academic organizations to bring innovative clinical products and technologies to the marketplace. Our Patient-centric Drug Discovery using Active Learning asset (“PeDAL”™) is a unique technology that combines our proprietary, clinically validated patient tumor cell line assay (“TruTumor”™), a vast knowledgebase of proprietary and public data together (“TumorSpace”™) with active learning - the active learning allowing the efficient exploration of compound drug responses against a large diverse patient “space”. PeDAL offers researchers the opportunity to efficiently and cost-effectively bring patient diversity much earlier in the drug discovery process. PeDAL works by iterative cycles of active-learning powered Learn-Predict-Test to guide the testing of patient-specific compound responses using the TruTumor assay and patient cell lines to build a comprehensive predictive model of patient responses to compounds. This predictive model can then be used to rank compounds by the fraction of patients of certain profiles that respond as well as the set of compounds that provide the best coverage across patients. PeDAL will be used in fee-for-service projects with pharmaceutical companies.

Contract Research Organization (“CRO”) and AI-Driven Business

We believe leveraging our unique, historical database of the drug responses of over 150,000 patient tumors to build AI and data-driven multi-omic predictive models of tumor drug response and outcome will provide actionable insights critical to both new drug development and individualizing patient treatment. Through the course of over 15 years of clinical testing of the responses of patient tumors to drugs, Helomics has amassed a huge proprietary knowledgebase of 150,000 patient cases. This data has been rigorously de-identified and aggregated to build a unique, proprietary model of tumor drug response that we call TumorSpace. The TumorSpace model and its data provide a priori knowledge for the machine learning approaches we employ as part of the PeDAL approach.

TumorSpace model provides a significant competitive advantage to our business offerings. PeDAL's unique patient and tumor-centric AI-driven approach can rapidly and cost-effectively screen hundreds of compounds in thousands of tumor cell lines, and gain valuable information about off-target effects and deliver:

● A ranked list of drug candidates by responsiveness

● Sets of drug candidates that provide maximum patient coverage

● Biomarker profiles of patients that respond to specific drug candidates

PeDAL also can deliver drug candidates targeted at a specific patient profile as early as the hit-to-lead stage of discovery, significantly increasing the chance of clinical success, leading to a dramatic improvement in both the success, time, and cost of your oncology discovery programs. The AI-driven models will also provide clinical decision support to help oncologists individualize treatment.

Our CRO/AI business leverages our core competence in profiling the drug response of patient tumors. Our large knowledgebase of tumor drug response and other data, together with proven AI, has created a unique capability for oncology drug discovery that allows for the highly efficient screening of drug responses from thousands of diverse, well-characterized patient primary tumor cell lines. This novel disruptive patient-centric approach is ideally suited to the early part of drug discovery (especially hit-to-lead, lead optimization, and pre-clinical), resulting in better prioritization of compounds and better coverage of patient diversity. This will dramatically improve the chances of successfully translating discoveries, resulting in lowered costs, shortened timelines, and most importantly enhanced “speed-to-patient” for new therapies.

Our CRO services business applies PeDAL to address a range of needs from discovery through clinical and translational research, to clinical trials and diagnostic development and validation as noted below:

Research
	●	Biomarker discovery
	●	Drug discovery
	●	Drug-repurposing
Development
	●	Patient enrichment & selection for trials
	●	Clinical trial optimization
	●	Adaptive trials

5

Clinical Decision Support
	●	Patient stratification
	●	Treatment selection

We believe this market segment has significant growth potential and we believe we are differentiated from traditional CRO’s and other precision medicine and AI companies through these unique assets:

● Clinically validated TruTumor platform;

● TumorSpace model of over 150,000 tumor cases;

● Experienced AI team and AI/Core® platform;

● Ability to access outcome data going back over ten years for over 120,000 of the tumor cases in our database.

Industry and Market Background and Analysis – Precision Medicine Business

Precision medicine is an emerging approach for disease treatment and prevention that considers individual variability in genes, disease, environment, and lifestyle for each case to develop effective therapies. This approach allows doctors and researchers to predict more accurately which treatment, dose, and therapeutic regimen could provide the best possible outcome.

Precision medicine, precisely targeting drugs based on the genomic profile of the patient, has become the aspiration for cancer therapy. Over the past several decades, researchers have identified molecular patterns that are useful in defining the prognosis of a given cancer, determining the appropriate treatments, and designing targeted treatments to address specific molecular alterations. The objective of this precision oncology is to develop treatments tailored to the genetic changes in each person’s cancer, intended to improve the effectiveness of the therapeutic regimen, and minimize the treatment’s effects on healthy cells. However, for a majority of patients the reality is that while many mutations in the patient’s tumor can be identified most are not actionable with current protocols, due to a lack of research regarding which mutations in a tumor confer a sensitivity to a particular drug. As a result, the impact of targeted therapies is low, and uptake in clinical practice is inconsistent.

There is now a growing realization that genomics alone will not be enough to achieve the promise of personalized therapeutics, especially for cancer. A multi-omic approach (e.g., assessing the genome, transcriptome, epigenome, proteome, responseome, and microbiome) provides researchers and clinicians the comprehensive information necessary for new drug development and individualized therapy. Comparatively, the multi-omic approach provides a three-dimensional, 360-degree view of the cancer, while genomics alone is just a flat, one-dimensional view. However, multi-omic data is difficult to access quickly as it is both costly and time consuming to initiate prospective data collection, and few comprehensive, multi-omic datasets exist, especially specific to cancer. Our Helomics TumorSpace database addresses this need.

Clinical Testing

Via our Helomics subsidiary, we offer a group of clinically relevant, cancer-related tumor profiling and biomarker tests for gynecological cancers that determine how likely the patient is to respond to various types of chemotherapy and which therapies might be indicated by relevant tumor biomarkers.

Clinic diagnostic testing is comprised of our Tumor Drug Response Testing (ChemoFx) and Genomic Profiling (BioSpeciFx) tests. The Tumor Drug Response Testing test determines how a patient’s tumor specimen reacts to a panel of various chemotherapy drugs, while the Genomic Profiling test evaluates the expression and/or status of a particular gene related to a patient’s tumor specimen. Our proprietary TruTumor platform provides us with the ability to work with actual live tumor cells to study the unique biology of the patient’s tumor in order to understand how the patient responds to treatment.

Testing involves obtaining tumor tissue during biopsy or surgery which is then sent to our Clinical Laboratory Improvement Amendments (“CLIA”) certified laboratory using a special collection kit. Tumor Drug Response Testing is a fresh tissue platform that uses the patient’s own live tumor cells to help physicians identify effective treatment options for each gynecologic cancer patient.

6

Genomic Profiling offers a select group of clinically relevant protein expression and genetic mutation tests associated with drug response and disease prognosis. Physicians can select biomarkers for testing from carefully chosen panels of relevant tests, intuitively organized by cancer pathway and tumor type. Results for these tests are presented in a clear, easy to understand format, including summaries of the clinical relevance of each marker.

Business Strategy for Precision Medicine Business

We are a data and AI-driven discovery services company that provides AI-driven predictive models of tumor drug response to improve clinical outcomes for patients by leveraging our two primary unique assets:

● TruTumor - a clinically validated tumor-profiling platform that can generate drug response profiles and other multi-omic data. Over $200 million has been invested in this platform by us and previous owners and was clinically validated in ovarian cancer.

● TumorSpace model contains data on the drug response profiles across 131 cancer types over 10+ years of clinical testing.

Over 38,000 of the more than 150,000 clinically validated cases in our TumorSpace database are specific to ovarian cancer. The data in TumorSpace is highly differentiated, having both drug response data, biomarkers, and access to historical outcome data from those patient samples. We intend to generate additional data (genomics and transcriptomics) from these tumor samples to deliver a multi-omic approach to the pharmaceutical industry.

Through our Helomics subsidiary, we will utilize both this historical data and the TumorSpace platform to build AI-driven predictive models of tumor drug response and outcome. During 2022, we will commercialize these AI-driven predictive models in revenue generating service projects with pharmaceutical, biotech, and diagnostic companies.

A key part of our commercialization strategy is the understanding that our AI-driven models of tumor drug response serve a key unmet need of pharmaceutical, diagnostic, and biotech industries for actionable multi-omic insights on cancer. In collaboration with these companies, using the predictive models, we will accelerate the search for more individualized and effective cancer treatments, through revenue generating projects in biomarker discovery, drug screening, drug repurposing, and clinical trials.

Our commercial strategy has identified a portfolio of revenue generating project types that leverage the predictive models, our AI expertise, PeDAL tumor profiling, and CLIA laboratory to provide custom solutions utilizing our full array of assets and expertise.

The Cancer Quest 2020 initiative focused initially on ovarian cancer, which is where we have the most expertise, samples, data, and access to outcomes. We are expanding the initiative to include cancers of the lung, breast, colon, and prostate, and will actively seek partners to assist in that effort.

We recently completed our product validation for Discovery 21in January 2022, the proof of concept for PeDAL, which incorporates CoRE™, our active machine learning program, with tumor profile data and human tumor samples, to efficiently determine the most effective drug treatment for a specific cancer type. With each iteration of PeDAL, the program learns, predicts, and then directs the most informative wet lab experimentation, while building the predictive model.

Discovery 21 is a predictive model, built in an efficient manner using PeDAL. The model revealed drug response patterns that provide insight into the treatment of ovarian cancer. The validation results demonstrated the accuracy of the model that predicted drug response. Within the clinical sector, we will also be able to utilize similar predictive models (once validated) for new clinical decision support tools for individualizing therapy for patients with cancer.

7

These clinical decision support tools are on a longer revenue horizon than the fee-for-service research projects with pharmaceutical companies but, importantly, will provide a steady stream of additional data generation to refine the predictive models for both clinical and research applications.

zPREDICTA

zPREDICTA develops tumor-specific in vitro models for oncology drug discovery and research by biopharmaceutical companies and other clients and partners. zPREDICTA’s 3D product models accelerate the drug development process for its clients and partners by leveraging the expertise in carcinogenesis, metastasis and the tumor microenvironment. It develops complex in vitro models that recapitulate the physiological environment of human tissue.

From target discovery and lead optimization to preclinical evaluation of efficacy and toxicity, the objective is to develop the tools necessary to accurately identify compounds that will have the highest probability of improving human health. Product offerings include preclinical testing services based on our proprietary models directly to clients in the biopharmaceutical industry.

zPREDICTA has expertise in creating human, disease-specific tissue microenvironments for testing drug efficacy and safety. Unlike other platforms, the patented 3D models utilize proprietary organ-specific extracellular matrix formulations that match the in vivo milieu of the organ of interest. These models reconstruct both cellular and extracellular compartments of each tissue, which is especially essential for testing of immuno-oncology agents.

zPREDICTA technology demonstrates high clinical relevance, enabling its pharma clients to manage pipeline attrition more efficiently by identifying drugs that are effective in patients, from the hundreds, and often thousands, of compounds in development. The tumor-specific models are used a number of biopharmaceutical companies to evaluate the efficacy and toxicity of their therapeutic pipelines. Our models replicate the extracellular matrix (“ECM”) of individual organs and disease-specific soluble microenvironment mimicking the biology of human disease, and as such, demonstrate high correlation with clinical response.

The zPREDICTA 3D tumor-specific models incorporate tissue-specific extracellular matrices and tumor-specific medium supplements allowing for a true reconstruction of tumor microenvironment. Our approach is compatible with multiple classes of immuno-oncology agents from naked antibodies and antibody-drug conjugates, to bi- and tri-specific compounds, and CAR-T cells. The organ-specific disease models provide 3D reconstruction of human tissues accurately representing each disease state and mimicking drug response.

Our platform incorporates both cellular and extracellular elements of tissue microenvironment in an organ- and disease-specific manner.

Extracellular components	Cell-cell interactions
●         extracellular matrix	●         tumor-tumor interactions
●         soluble factors (cytokines, etc.)	●         tumor-stroma interactions

Our platform is designed to evaluate drug candidates and drug combinations within the native microenvironment of human tissues. Our technology is a patient-derived 3D culture platform that recreates the complex human organ microenvironment thereby preserving the critical interactions between a tumor and its surroundings. Our platform supports long-term survival and proliferation of malignant and non-malignant cellular components of tissues. This includes tumor cells, stroma, and immune components. Anticancer compounds tested in our models exhibit high correlation with clinical response when comparing treatment outcomes in the clinic with cellular behavior in response to the therapeutic regimen. Our organ-specific technology is compatible with multiple drug classes, including small molecules, antibodies, antibody-drug conjugates, immunomodulatory agents, CAR-T cells, etc. Our platform is fully customizable to the tumor and tissue of interest. It is compatible with multiple cell types, drug classes, and downstream analysis methods.

8

Applications include providing efficacy screening of anticancer compounds, evaluation of mechanisms of drug resistance, identification of new drug combinations, rescue of failed drug candidates, assessment of off-target toxicity, target discovery and biomarker discovery.

SOLUBLE BIOTECH

Our subsidiary, Soluble Biotech Inc. (“Soluble”), focuses on contract services and research for biopharmaceutical company clients and academic collaborators, focused on solubility improvements, stability studies, and protein production. Specifically, Soluble provides optimized FDA-approved formulations for vaccines, antibodies, and other protein therapeutics in a faster and lower cost basis to its customers. In addition, Soluble enables protein degradation studies, which based on current projections, potentially substantial line of business for the Company.

The primary assets of Soluble are our automated High Throughput Self-Interaction Chromatography (HSC™). HSC is a self-contained, automated system that conducts high-throughput, self-interaction chromatography screens on excipients previously approved by the FDA for protein formulations. Our technology measures second virial coefficient (B22 value) of protein-protein interactions to identify excipients that promote protein solubility in solutions. The data generated from HSC screens are analyzed by a proprietary predictive algorithm to identify the optimal combination(s) of buffers, pH, and excipients, resulting in increased solubility and physical stability of proteins. Several of our clients have seen ten-fold and hundred-fold increases in their protein’s solubility while maintaining physical stability. For biopharmaceutical clients this means faster development times and quicker progression of molecules into the clinic. For academic collaborators, this means further progression of biochemical & biology studies necessary to advance fundamental research in areas of unmet medical need.

In addition, Soluble provides comprehensive protein stability analysis. Analysis via time-dependent shelf-life studies and forced degradation studies designed to quickly determine which of the previously FDA approved additives that will improve the solubility and stability of proteins in solutions. Services include pre-formulation development, stability assessment, and biophysical characterization which evaluate variables including pH, temperature, humidity, light, oxidizing agents, and mechanical stress to determine the most promising additives, formulation of B22 values and confirmation on conformation stability. We provide clients with a list of the most promising additives from a set of over 40 different additives that can increase the solubility and stability of protein formulations.

Soluble also offers protein solubility kits that allow rapid identification of soluble formulations. We provide four different kits to fulfill customer solubility requirements. The kits are in 96-well format and provide the tools and methods to compare relative solubility across 88 common formulations (with 8 controls). Soluble kits utilize a simple mix and spin protocol that quickly evaluates aggregation behavior as a function of pH, salt, and additives costing significantly less than if manually determined. In addition, we provide innovative technologies for bacterial detection and removal in therapeutic proteins that continue to be a significant issue in the pharmaceutical field.

In addition, Soluble supplies proprietary technologies for bacterial endotoxin detection and removal. Endotoxin is an inherent byproduct of bacterial expression of therapeutic proteins. However, therapeutic proteins are required to have extremely low endotoxin levels. Soluble provides a product to remove endotoxin that works through multiple molecular interactions for efficient removal over a wide range of buffer conditions with minimal product loss. The detection of endotoxin can also be adversely affected by the protein therapeutic itself. To address this, Soluble provides sample treatment kits to minimize detection interference while using standard detection assays.

SKYLINE MEDICAL – The STREAMWAY System

Sold through our subsidiary, Skyline Medical Inc. (“Skyline Medical”), the STREAMWAY System virtually eliminates staff exposure to blood, irrigation fluid, and other potentially infectious fluids found in the healthcare environment. Antiquated manual fluid handling methods that require hand carrying and emptying filled fluid canisters present both an exposure risk and potential liability. Skyline Medical’s STREAMWAY System fully automates the collection, measurement, and disposal of waste fluids and is designed to: 1) reduce overhead costs to hospitals and surgical centers; 2) improve compliance with the Occupational Safety and Health Administration (“OSHA”) and other regulatory agency safety guidelines; 3) improve efficiency in the operating room and radiology and endoscopy departments, thereby leading to greater profitability; and 4) provide greater environmental stewardship by helping to eliminate the approximately 50 million potentially disease-infected canisters that go into landfills each year in the United States. We continue to operate the Skyline Medical business by continually improving our strategic opportunities, while focusing our resources on our precision medicine business.

Industry and Market Background and Analysis - Infectious and Biohazardous Waste Management

There has long been recognition of the collective potential for ill effects to healthcare workers from exposure to infectious/biohazardous materials. Federal and state regulatory agencies have issued mandatory guidelines for the control of such materials, and in particular, bloodborne pathogens. OSHA’s Bloodborne Pathogens Standard (29 CFR 1910.1030) requires employers to adopt engineering and work practice controls that would eliminate or minimize employee exposure from hazards associated with bloodborne pathogens. In 2001, in response to the Needlestick Safety and Prevention Act, OSHA revised the Bloodborne Pathogens Standard. The revised standard clarifies and emphasizes the need for employers to select safer needle devices and to involve employees in identifying and choosing these devices. The revised standard also calls for the use of “automated controls” as it pertains to the minimization of healthcare exposure to bloodborne pathogens.

Most surgical procedures produce potentially infectious materials that must be disposed with the lowest possible risk of cross-contamination to healthcare workers. Current standards of care allow for these fluids to be retained in canisters and located in the operating room where they can be monitored throughout the surgical procedure. Once the procedure is complete these canisters and their contents are disposed using a variety of methods, all of which include manual handling and result in a heightened risk to healthcare workers for exposure to their contents. Canisters are the most prevalent means of collecting and disposing of infectious fluids in hospitals today. Traditional, non-powered canisters and related suction and fluid disposable products are exempt and do not require FDA clearance. 

We believe that our virtually hands free direct-to-drain technology (1) significantly reduces the risk of healthcare worker exposure to these infectious fluids by replacing canisters, (2) further reduces the risk of worker exposure when compared to powered canister technology that requires transport to and from the operating room, (3) reduces the cost per procedure for handling these fluids, and (4) enhances the surgical team’s ability to collect data to accurately assess the patient’s status during and after procedures. In addition to the traditional canister method of waste fluid disposal, several other powered medical devices have been developed that address some of the deficiencies described above. Most of these competing products continue to utilize some variation on the existing canister technology, and while not directly addressing the canister, most have been successful in eliminating the need for an expensive gel and its associated handling and disposal costs.  Our existing competitors with products already on the market have a clear competitive advantage over us in terms of brand recognition and market exposure. In addition, many of our competitors have extensive marketing and development budgets that could overpower an emerging growth company like ours.

We expect the hospital surgery market to continue to increase due to population growth, the aging of the population, and expansion of surgical procedures to new areas (for example, use of the endoscope) which requires more fluid management and new medical technology.

STREAMWAY System Product Sales

Our Skyline Medical division consists primarily of sales of the STREAMWAY System, as well as sales of the proprietary cleaning fluid and filters for use with the STREAMWAY System. We manufacture an environmentally conscious system for the collection and disposal of infectious fluids resulting from surgical and other medical procedures. We have been granted patents for the STREAMWAY System in the United States, Canada, and Europe. We distribute our products to medical facilities where bodily and irrigation fluids produced during medical procedures must be contained, measured, documented, and disposed. Our products minimize the exposure potential to the healthcare workers who handle such fluids.

The STREAMWAY System is a wall-mounted fully automated system that disposes of an unlimited amount of suction fluid providing uninterrupted performance for physicians while virtually eliminating healthcare workers’ exposure to potentially infectious fluids collected during surgical and other patient procedures. We also manufacture and sell two disposable products required for the operation of the STREAMWAY System: a bifurcated dual port procedure filter with tissue trap and a single use bottle of cleaning solution. Both items are utilized on a single procedure basis and must be discarded after use. The STREAMWAY disposables are a critical component of our business model. Recurring revenues from the sale of the disposables are expected to be significantly higher over time than the revenues from the initial sale of the unit. We have exclusive distribution rights to the disposable solution.

TUMORGENESIS

Our subsidiary TumorGenesis is our research and development arm for Helomics and zPREDICTA. TumorGenesis also specializes in media that help cancer cells grow outside the patient’s body and retain their DNA/RNA and proteomic signatures. With this tool, researchers are able to expand and study cancer cell types inherent in blood tumors and organ systems of all mammals, including humans.

Competition and Competitive Advantages

Precision Medicine Business. We presently have clinical information, including tumor drug response data and an in-house bioinformatics AI platform. Cancer treatments require at least 5 years of testing to see progression-free survival rates. While competitors must wait for this data, we can leverage that data today. Other companies within our market segment are spending significant investment dollars to generate this data which they cannot leverage until the future. We can leverage the data today by sequencing the tumors and gathering the outcome data which is measured in months instead of years. In addition, the following points detail the key differentiators in our model building approach.

● AI Models are built with real world data on how patient tumors responded to drugs, together with clinical outcome (progression-free survival/overall survival).

● We believe this patient-centric, highly standardized, and curated, multi-omic tumor model offers a better chance of generating serviceable predictive models of drug-response and outcomes than competitive approaches in the market today. The information embodied in the AI-driven predictive model provides insights into each tumor’s response to different therapeutic options, resulting in the ability to provide actionable insights critical to both new drug development and individualizing patient treatment.

zPREDICTA. Our next-generation technology based on extensive research of the human tumor microenvironment creating accurate reconstruction of the organ-specific 3D tissue microenvironment enabling evaluation of therapeutic agents under conditions mimicking human physiology. The main competitive advantage of zPREDICTA’s technology is the tumor-specific nature of its systems. 3D models replicate tissue heterogeneity and provides long-term maintenance of primary human cells, organoids, and cell lines under the native conditions of human disease. The 3D models are formulated to mimic the tissue and disease of interest instead of pursuing a one-size-fits-all approach taken by other companies. Services provide reliable prediction of clinical outcomes based on accurate reconstruction of cellular and extracellular compartments of human tissues.

Soluble Biotech. HSC Technology is a self-contained, automated system that conducts high-throughput, self-interaction chromatography screens on FDA approved excipients for protein formulations. The HSC Instrument and its technology has been validated over the past twelve years via industry and academic collaborations. The data generated from HSC screens are analyzed by a proprietary predictive algorithm to identify the optimal combination(s) of buffers, pH, and excipients, resulting in increased solubility and physical stability of proteins. Several of our clients have seen ten-fold and hundred-fold increases in their protein’s solubility while maintaining physical stability. For biopharmaceutical clients this means faster development times and quicker progression of molecules into the clinic.

Skyline Medical. We believe that the STREAMWAY System is unique to the industry in that it not only allows continuous suction but also provides for unlimited capacity, eliminating the need to interrupt a procedure to change canisters. To our knowledge, the STREAMWAY System is the only known fully automated direct‐to‐drain system that is wall‐mounted and able to collect, measure, and dispose of an unlimited amount of waste fluid without interruption.

We buy our raw materials from several suppliers and, except as set forth below, the loss of any one supplier would not materially adversely affect our business. We rely on sole suppliers for certain materials used to perform our molecular diagnostic tests. We also purchase reagents used in our molecular diagnostic tests from sole-source suppliers. While we have developed alternate sourcing strategies for these materials and vendors, we cannot be certain that these strategies will be effective or that the alternative sources will be available in a timely manner. If our current suppliers can no longer provide us with the materials, we need to perform molecular diagnostic tests, if the materials do not meet our quality specifications, or if we cannot obtain acceptable substitute materials, there could be an interruption in molecular diagnostic test processing. In the event of the loss of these suppliers, we could experience delays and interruptions that might adversely affect the financial performance of our business.

We also have single suppliers for the manufacturing of certain of our Skyline Medical products. Alternative suppliers are available in the market; however, we could experience delays and interruptions that might adversely affect the financial performance of our business including time for machine tooling specific to our products.

We have existing and good relationships with our service vendors.

Research and Development (“R&D”)

We spent $315,850 and $372,710 in 2021 and 2020, respectively, on R&D. 

Intellectual Property

We believe that to maintain a competitive advantage in the marketplace, we must develop and maintain protection of the proprietary aspects of our technology. We rely on a combination of patent, trade secret intellectual property rights, and other measures to protect our intellectual property to develop and maintain our competitive position. We seek to protect our trade secrets and proprietary know-how, in part, with confidentiality agreements with employees, although we cannot be certain that the agreements will not be breached, or that we will have adequate remedies if a breach were to occur.

zPREDICTA. Our technology is a patient-derived 3D culture platform that recreates the complex human organ microenvironment thereby preserving the critical interactions between a tumor and its surroundings. Our models replicate the extracellular matrix of individual organs and disease-specific soluble microenvironment mimicking the biology of human disease, and as such, demonstrate high correlation with clinical response. Patents include US10,501,717, US11,124,756 and pending application US16/321,277.

Skyline Medical. In general, our patents are directed to a system and method for collecting waste fluid from a surgical procedure while ensuring there is no interruption of suction during the surgical procedure and no limit on the volume of waste fluid that can be collected. We hold the following granted patents in the United States, and a pending application in the United States on our earlier STREAMWAY System models: US7469727, US8123731, and US Publication No. US20090216205 (collectively, the “Patents”). The Patents will begin to expire on August 8, 2023.

On January 25, 2014, we filed a non-provisional Patent Cooperation Treaty (“PCT”) Application No. PCT/US2014/013081 claiming priority from the U.S. Provisional Patent Application, number 61756763 which was filed on January 25, 2013. The PCT allows an applicant to file a single patent application to seek patent protection for an invention simultaneously in each of the 148-member countries of the PCT, including the United States.

The United States Patent Office has assigned application #14/763,459 to our previously filed PCT application.

As of November 22, 2017, we were informed that the European Patent Office allowed all our claims for application #14743665.3-1651 and on as of July 11, 2018, we were informed that the European Patent #EP2948200 was granted and published validating in the following countries: Belgium, Germany, Spain, France, United Kingdom, Ireland, Italy, Netherlands, Norway, Poland, and Sweden. Our PCT patent application is for an enhanced model of the surgical fluid waste management system. We utilize this enhanced technology in the updated version of the STREAMWAY System unit we began selling in 2014.

Government Regulation

Our businesses are subject to or impacted by extensive and frequently changing laws and regulations in the United States (at both the federal and state levels) and the other jurisdictions in which we conduct business, including some specific to our business, some specific to our industry, and others relating to conducting business generally (e.g., U.S. Foreign Corrupt Practices Act). We also are subject to inspections and audits by governmental agencies. The table below highlights key regulatory schemes applicable to our businesses:

CLIA and State Clinical Laboratory Licensing	CLIA regulates the operations of virtually all clinical laboratories, requiring that they be certified by the federal government and that they comply with various technical, operational, personnel, and quality requirements intended to ensure that the services provided are accurate, reliable, and timely. State laws may require additional personnel qualifications or licenses, quality control, record maintenance, proficiency testing, or detailed review of our scientific method validations and technical procedures for certain tests. Violations of these laws and regulations may result in monetary fines, criminal and civil penalties and/or suspension or exclusion from participation in Medicare, Medicaid, and other federal or state healthcare programs.
Medicare and Medicaid; Fraud and Abuse	Diagnostic testing services provided under Medicare and Medicaid programs are subject to complex, evolving, stringent, and frequently ambiguous federal and state laws, and regulations, including those relating to billing, coverage, and reimbursement. Anti-kickback laws and regulations prohibit making payments or furnishing other benefits to influence the referral of tests billed to Medicare, Medicaid, or certain other federal or state healthcare programs. In addition, federal and state anti-self-referral laws generally prohibit Medicare and Medicaid payments for clinical tests referred by physicians who have an ownership or investment interest in, or a compensation arrangement with, the testing laboratory, unless specific exceptions are met. Federal substance abuse legislation enacted in 2018 contains anti-kickback provisions that are, by their terms, applicable to laboratory testing paid for by all payers. Upon full review of the legislation, we were in compliance at that time and continue to maintain compliance. We monitor regularly and reflect this in our annual compliance report. Some states have similar laws that are not limited in applicability to only Medicare and Medicaid referrals and could also affect tests that are paid for by health plans and other non-governmental payers. Violations of these laws and regulations may result in monetary fines, criminal and civil penalties and/or suspension or exclusion from participation in Medicare, Medicaid, and other federal or state healthcare programs.
FDA	The FDA has potential regulatory responsibility over, among other areas, instruments, software, test kits, reagents and other devices used by clinical laboratories to perform diagnostic testing in the United States. The FDA may assert regulatory oversight over these areas, and legislative proposals addressing FDA oversight of laboratory developed tests have been introduced in the past and may be enacted in the future. See “Item 1A. Risk Factors” for a discussion of the possible impact of such regulatory or legislative developments.

13

Environmental, Health and Safety	We are subject to laws and regulations related to the protection of the environment, the health and safety of employees, and the handling, transportation, and disposal of medical specimens, infectious and hazardous waste, radioactive materials, various aspects of pertinent technologies and methods of protection.
	Several organizations maintain oversight function including:
	●	OSHA (Occupational Safety and Health Administration)
	●	EPA (Environmental Protection Agency)
	●	DOT (Department of Transportation)
	●	USPS (US Postal Service)
	●	US Public Health Service
	●	JCAHO (Joint Commission on Accreditation of Healthcare Organizations)
	●	NFPA (National Fire Protection Association)
	●	AIA (American Institute of Architects)
	●	AORN (Association of Operating Room Nurses)
Privacy and Security of Health and Personal Information	We are subject to laws and regulations regarding protecting the security and privacy of certain healthcare and personal information, including: (1) the federal Health Insurance Portability and Accountability Act and the regulations thereunder, which establish (a) a complex regulatory framework including requirements for safeguarding protected health information and (b) comprehensive federal standards regarding the uses and disclosures of protected health information; (2) state laws; and (3) the European Union's General Data Protection Regulation. A healthcare provider may be subject to penalties for non-compliance and may be required to notify individuals or state, federal, or county governments if the provider discovers certain breaches of personal information or protected health information.

To date, no regulatory agency has established exclusive jurisdiction over the area of biohazardous and infectious waste in healthcare facilities.

FDA Clearance of STREAMWAY System under Section 510(k)

The FDA Center for Devices and Radiological Health requires 510(k) submitters to provide information that compares its new device to a marketed device of a similar type, in order to determine whether the device is substantially equivalent.

We filed the 510(k) submission for clearance of the STREAMWAY System device on March 14, 2009 and received written confirmation on April 1, 2009 that our 510(k) has been cleared by the FDA.

Following this 510(k) clearance by the FDA, we continue to be subject to the normal ongoing audits and reviews by the FDA and other governing agencies. These audits and reviews are standard and typical in the medical device industry, and we do not anticipate being affected by any extraordinary guidelines or regulations.

Our subsidiary, Skyline Medical has successfully passed FDA audits in the past, with no observations or 483 warning letters issued.

Application for Electrical Safety Testing and Certification for STREAMWAY System

We sought and achieved testing and certification to the IEC 60606-1 and IEC 60606-1-2, two internationally recognized standards.

The 60601-1 3^rd edition certification for our STREAMWAY System is valid and enables us to continue to market and sell our product domestically and internationally.

We have contracted with TUV, a nationally recognized testing laboratory-NRTL, to certify our STREAMWAY System to the new 60601-1 3^rd Edition in late 2016. We attained certification to the new standard, and then submitted it to our Notified Body (BSI) for recommendation for our CE Mark, which we received in June 2017, allowing us to sell products outside of the United States.

14

Effective November 21, 2016, we received a Medical Device Establishment License to sell the STREAMWAY System and related disposables in Canada.

ISO Certification

Our subsidiary, Skyline Medical, hired BSI (British Standards Institute) to be its Notified Body and to perform audits to ISO 13485:2003 Standards. On June 1, 2016, we successfully passed the audit of our Quality Management System and received our Certificate of Registration for ISO 13485:2016. Our certificate number is FM 649810.

Employees

We have 30 full-time employees and 2 part-time employees as of December 31, 2021.

Executive Offices

Our principal executive offices are located at 2915 Commers Drive; Suite 900; Eagan, Minnesota 55121 and our telephone number is (651) 389-4800.

Risk Factors Relating to Our Business

Our limited operating history with respect to our precision medicine services makes evaluation of our business difficult. 

Our precision medicine services were launched with the initial investment in Helomics during the first quarter of 2018 and have not generated significant revenue to date. Our ability to implement a successful business plan with respect to precision medicine remains unproven and no assurance can be given that we will ever generate sufficient revenues to sustain our business. We have a limited operating history which makes it difficult to evaluate our performance. Our prospects should be considered in light of these risks, and the expenses, technical obstacles, difficulties, market penetration rate, and delays frequently encountered in connection with the development of new businesses. These factors include uncertainty as to whether we will be able to: 

● Succeed in uncertain markets;

● Respond effectively to competitive pressures;

● Successfully address intellectual property issues of others;

● Protect and expand our intellectual property rights; and

● Continue to develop and upgrade our products.

In connection with developing our CRO business, we have committed and will continue to commit significant capital to investments in early-stage companies, all of which may be lost, and which may require us to raise significant additional capital, and our entering into new lines of business will result in significant diversion of management resources, all of which may result in failure of our business.

We have committed significant capital and management resources to developing our CRO business and other new business areas, and we intend to continue to devote significant capital and management resources to new businesses. Therefore, we could invest significant capital in business enterprises with no certainty when or whether we will realize a return on these investments. Investments using cash will deplete our capital resources, meaning we will be required to raise significant amounts of new capital. There is no assurance that we will be successful in raising sufficient capital, and the terms of any such financing will be dilutive to our stockholders. We may also acquire technologies or companies by issuing stock or other equity securities rather than, or in addition to, payment of cash, which may have the result of diluting our stockholders’ investments. Further, the energy and resources of our officers and personnel may be substantially diverted to new lines of business, which are unproven. If these businesses are unsuccessful or require too great of a financial investment to be profitable, our business may fail.

We rely on sole suppliers for some of the materials used in our molecular diagnostic tests, and we may not be able to find replacements or transition to alternative suppliers in a timely manner.

We rely on sole suppliers for certain materials used to perform our molecular diagnostic tests. We also purchase reagents used in our molecular diagnostic tests from sole-source suppliers. While we have developed alternate sourcing strategies for these materials and vendors, we cannot be certain whether these strategies will be effective, or the alternative sources will be available in a timely manner. If these suppliers can no longer provide us with the materials needed to perform our molecular diagnostic tests, if the materials do not meet required quality specifications, or if we cannot obtain acceptable substitute materials, an interruption in molecular diagnostic test processing could occur. Any such interruption may directly impact our revenue and cause us to incur higher costs.

16

If we are sued for product liability or errors and omissions liability, we could face substantial liabilities that exceed our resources.

The marketing, sale, and use of our molecular diagnostic tests could lead to product liability claims if someone were to allege that the molecular diagnostic test failed to perform as it was designed. We may also be subject to liability for errors in the results we provide to physicians or for a misunderstanding of, or inappropriate reliance upon, the information we provide. A product liability or errors and omissions liability claim could result in substantial damages and be costly and time consuming for us to defend. Although we maintain product liability and errors and omissions insurance, we cannot be certain that our insurance would fully protect us from the financial impact of defending against these types of claims or any judgments, fines, or settlement costs arising out of such claims. Any product liability or errors and omissions liability claim brought against us, with or without merit, could increase our insurance rates or prevent us from securing insurance coverage in the future. Additionally, any product liability lawsuit could cause injury to our reputation or cause us to suspend sales of our products and solutions. The occurrence of any of these events could have a material adverse effect on our business, financial condition, and results of operations.

If our R&D and commercialization efforts for our TruTumor and PeDAL platforms take longer than expected, the commercial revenues from the service offerings that use these platforms could also be delayed.

Our CRO business offers various services to pharma, diagnostics, and biotech companies. These services use our TruTumor tumor platform and our PeDAL platform. These platforms are the subject of active R&D to further improve them for commercial use in order to help our clients in their drug discovery, biomarker, and clinical trial activities. We could face delays in this R&D, for example:

● we may not be able to secure access to and approval to use clinical data from academic hospital partners in a timely manner;

● clinical testing volume (number of specimens coming to us for testing) may not grow sufficiently to drive additional data generation as well as further development of the TruTumor platform;

● patient consent to use the patient’s data and tumor material for R&D may not be sufficient to support R&D; and

● we may not be able to attract and retain the appropriately qualified staff to perform the necessary R&D.

We have a limited operating history with the CRO business particularly services using our PeDAL, platform as these are new to the market, which makes it difficult to forecast our future revenues. While we are committed to the buildout of the CRO services for the long term, we cannot predict at this time, with any certainty, the future viability of either business unit.

We face significant competition in the surgical fluid waste management industry, including competition from companies with considerably greater resources than ours, and if we are unable to compete effectively with these companies, our market share may decline, and our business could be harmed.

The surgical fluid waste management industry is highly competitive with numerous competitors ranging from well-established manufacturers to innovative start-ups. Several of our competitors have significantly greater financial, technological, engineering, manufacturing, marketing, and distribution resources than we do. Their greater capabilities in these areas may enable them to compete more effectively on the basis of price and production and more quickly develop new products and technologies.

Companies with significantly greater resources than ours may be able to reverse engineer our products and/or circumvent our intellectual property position. Such action, if successful, would greatly reduce our competitive advantage in the marketplace.

We believe our ability to compete successfully with our STREAMWAY System depends on a number of factors, including, without limitation, our technical innovations of unlimited suction and unlimited capacity capabilities, our innovative and advanced research and development capabilities, strength of our intellectual property rights, sales and distribution channels, and advanced manufacturing capabilities. We plan to employ these and other elements as we develop our products and technologies, but there are many other factors beyond our control. We may not be able to compete successfully in the future, and increased competition may result in price reductions, reduced profit margins, loss of market share, and an inability to generate cash flows that are sufficient to maintain or expand our development and marketing of new products, which could adversely impact the trading price of the shares of our common stock.

17

If demand for our STREAMWAY System or molecular diagnostic tests is unexpectedly high or if we experience problems in scaling our operations, there is no assurance that there will not be supply interruptions or delays that could limit the growth of our revenue.

We have contracted with a manufacturing company that follows ISO compliance regulations of the FDA and that can manufacture products at high volumes. However, if demand for our product is higher than anticipated, there is no assurance that we or our manufacturing partners will be able to produce the product in sufficiently higher quantity to satisfy demands.

Likewise, as demand for our molecular diagnostic tests grow, we will need to continue to scale our testing capacity and processing technology to expand our customer service, billing, and systems processes and to enhance our internal quality assurance program. We will also need additional certified laboratory scientists and other scientific and technical personnel to process higher volumes of our molecular diagnostic tests. We cannot guarantee that increases in scale, related improvements, and quality assurance will be implemented successfully or that appropriate personnel will be available. Failure to implement necessary procedures, transition to new processes, or hire the necessary personnel could result in higher costs of processing tests or an inability to meet demand. There can be no assurance that we will be able to perform our testing on a timely basis at a level consistent with demand, or that our efforts to scale our operations will not negatively affect the quality of test results.

If we encounter difficulties in scaling our operations as a result of, among other things, quality control and quality assurance issues and availability of reagents and raw material supplies, we will likely experience reduced sales, increased repair or re-engineering costs, defects, and increased expenses due to switching to alternate suppliers. Any of these results would reduce our revenues and gross margins. Although we attempt to match our capabilities to estimates of marketplace demand, to the extent demand materially varies from our estimates, we may experience constraints in our operations and delivery capacity, which could adversely impact revenue in a given fiscal period. Any supply interruptions or inadequate supply would have a material adverse effect on our results of operations.

If we encounter difficulty meeting market demand or quality standards our reputation could be harmed, and our future prospects and business could suffer, causing a material adverse effect on our business, financial condition, and results of operations.

We may require additional financing to finance operating expenses and fulfill our business plan. Such financing, if available, will be dilutive.

We have not achieved profitability and anticipate that we will continue to incur net losses at least through the remainder of 2022. We may need to raise additional capital to finance operating expenses, invest in our sales organization and new product development, compete in the international marketplace, and develop the strategic assets of our Helomics businesses, especially over the longer term. We would attempt to raise these funds through equity or debt financing that may include public offerings, private placements, alternative offerings, further draws on our equity line with Oasis Capital, LLC, or other means. Such additional financing would be dilutive to existing stockholders, and there is no assurance that such financing would be available upon acceptable terms. If such financing or adequate funds from operations are not available, we would be forced to limit our business activities, which would have a material adverse effect on our results of operations and financial condition. These possibilities, to the extent available, may be on terms that result in significant dilution to our existing shareholders or that result in our existing shareholders losing part or all of their investment.

18

Our business and operations have been and will likely continue to be materially and adversely affected by the COVID-19 pandemic.

The current COVID-19 worldwide pandemic has presented substantial public health challenges. In response to the crisis, emergency measures have been imposed by governments worldwide, including mandatory social distancing and the shutdown of non-essential businesses. These measures have adversely impacted the global economy, disrupted global supply chains and created significant volatility and disruption of financial markets, and our business and operations have been and will likely continue to be materially and adversely affected. For example, our contract manufacturer for the STREAMWAY® System has been forced to change locations, thereby delaying our order fulfillment for parts. We have also reduced on-site staff at several of our facilities, resulting in delayed production, less efficiency, and our sales staff is unable to visit with hospital administrators who are our customers and potential customers. In addition, COVID-19 has impacted the Company’s capital and financial resources, including our overall liquidity position and outlook. For instance, our accounts receivable has slowed while our suppliers continue to ask for pre-delivery deposits. Ultimately, the extent of the impact of the COVID-19 pandemic on our future operational and financial performance will depend on, among other matters, the duration and intensity of the pandemic; the level of success of global vaccination efforts; governmental and private sector responses to the pandemic and the impact of such responses on us; and the impact of the pandemic on our employees, customers, suppliers, operations and sales, all of which are uncertain and cannot be predicted. These factors may remain prevalent for a significant period of time even after the pandemic subsides, including due to a continued or prolonged recession in the U.S. or other major economies. Even in areas where "stay-at-home" restrictions, masking and social distancing measures have been lifted and the number of COVID-19 cases have declined, some jurisdictions may re-impose these measures as and if variant strains emerge or cases rise. The impacts of the COVID-19 pandemic, as with any adverse public health developments, could have a material adverse effect on our business, results of operations, liquidity or financial condition and heighten or exacerbate risks described in this Annual Report on Form 10-K.

We are dependent on a few key executive officers for our success. Our inability to retain those officers would impede our business plan and growth strategies, which would have a negative impact on our business and the value of an investment.

Our success depends on the skills, experience, and performance of key members of our management team. We heavily depend on our management team: J. Melville Engle, our Chief Executive Officer (“CEO”), and Bob Myers, our Chief Financial Officer (“CFO”). We have entered into employment agreements with the CEO and the CFO and may expand the relatively small number of executives. Were we to lose one or more of these key individuals, we would be forced to expend significant time and money in the pursuit of a replacement, which could result in both a delay in the implementation of our business plan and the diversion of our limited working capital. We can give no assurance that we would be able to find satisfactory replacements for these key individuals at all, or on terms that are not unduly expensive or burdensome to us.

If we are required to write down goodwill and other intangible assets, our financial condition and operating results would be negatively affected.

When we acquire a business, a substantial portion of the purchase price of the acquisition is allocated to goodwill and other identifiable intangible assets. The amount of the purchase price which is allocated to goodwill and other intangible assets is determined by the excess of the purchase price over the net identifiable assets acquired. For example, when we acquired Helomics, we acquired $3,725,000 in intangible assets and $23,790,290 in goodwill, which represented the excess of the consideration transferred over the fair values of assets acquired and liabilities assumed and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. We test intangible assets and goodwill for impairment at least annually. During the year ended December 31, 2021, we recorded an impairment of goodwill completing the full impairment of the goodwill acquired at the acquisition of Helomics in 2019. We also recorded a full impairment of the net book value of our intangible assets acquired at the acquisition of Helomics in 2019. On November 24, 2021, we acquired $6,857,790 in goodwill and $3,780,000 of intangible assets as a part of our acquisition of zPREDICTA. Under current accounting standards, if we determine that intangible assets or goodwill are impaired in the future, we will be required to write down these assets. Any write-downs that may be required to be recorded would adversely affect our financial condition and operating results.

19

We may fail to realize the anticipated benefits of the zPREDICTA acquisition.

The success of the zPREDICTA acquisition will depend, in part, on our ability to realize the anticipated growth opportunities and synergies from combining our companies, Predictive and zPREDICTA. The integration will be a time consuming and expensive process and may disrupt our operations if it is not completed in a timely and efficient manner. In addition, we may not achieve anticipated synergies or other benefits of the merger. Following the merger, we operate as a combined organization utilizing common information and communication systems, operating procedures, financial controls, and human resources practices. We may encounter the following integration difficulties, resulting in costs and delays:

● failure to successfully manage relationships with customers and other important relationships;

● failure of customers to continue using our services;

● difficulties in successfully integrating our management teams and employees;

● challenges encountered in managing larger operations;

● losses of key employees;

● failure to manage our growth and growth strategies;

● diversion of the attention of management from other ongoing business concerns;

● incompatibility of technologies and systems;

● impairment charges incurred to write down the carrying amount of intangible assets generated as a result of the merger; and

● incompatibility of business cultures.

If our operations after the merger do not meet the expectations of our existing or prospective customers, then these customers and prospective customers may cease doing business with us altogether, which would harm our results of operations, financial condition, and business prospects. If the management team is not able to develop strategies and implement a business plan that successfully addresses these difficulties, we may not realize the anticipated benefits of the merger.

Risks Related to Our Intellectual Property

Our business is dependent upon proprietary intellectual property rights, which if we were unable to protect, could have a material adverse effect on our business. 

We rely on a combination of patent, trade secret and other intellectual property rights, contractual restrictions, and other measures to protect our intellectual property. We currently own and may in the future own or license additional patent rights or trade secrets in the U.S., with non-provisional patents elsewhere in the world that cover certain of our products. We rely on patent laws and other intellectual property laws, nondisclosure and other contractual provisions, and technical measures to protect our products and intangible assets.

If we fail to protect our intellectual property, third parties may be able to compete more effectively against us and we may incur substantial litigation costs in our attempts to recover or restrict use of our intellectual property. While we apply for patents covering our products and technologies and uses thereof, we may fail to apply for patents on important products and technologies in a timely fashion, or at all, or we may fail to apply for patents in relevant jurisdictions. Others could seek to design around our current or future patented technologies. These intellectual property rights are important to our ongoing operations and no assurance can be given that any measure we implement will be sufficient to protect our intellectual property rights.

Further, competitors could willfully infringe upon our intellectual property rights, design around our protected technology, or develop their own competitive technologies that arguably fall outside of our intellectual property rights. Others may independently develop similar or alternative products and technologies or replicate any of our products and technologies. Also, with respect to our trade secrets and proprietary know-how, we cannot be certain that the confidentiality agreements we have entered into with employees will not be breached, or that we will have adequate remedies for any breach. In addition, we may lose the protection afforded by these rights through patent expirations, legal challenges, or governmental action. If our intellectual property does not adequately protect us against competitors’ products and methods, our competitive position could be adversely affected, as could our business and the results of our operations. To the extent our intellectual property offers inadequate protection, or is found to be invalid or unenforceable, we would be exposed to a greater risk of competition. If our intellectual property does not provide adequate coverage of our competitors’ products, our competitive position could be adversely affected, as could our overall business.

20

If we become subject to intellectual property actions, it could hinder our ability to deliver our products and services and our business could be negatively impacted.

We could be subject to legal or regulatory actions alleging intellectual property infringement or similar claims against us. Companies may apply for or be awarded patents or have other intellectual property rights covering aspects of our technologies or businesses. Litigation may be necessary for us to enforce our patents and proprietary rights or to determine the scope, coverage, and validity of the proprietary rights of others. The outcome of any litigation or other proceeding is inherently uncertain and might not be favorable to us, and we might not be able to obtain licenses to technology that we require on acceptable terms, or at all. Moreover, if it is determined that our products infringe on the intellectual property rights of third parties, we could be prevented from marketing our products. While we are currently not subject to any material intellectual property litigation, any future litigation alleging intellectual property infringement could be costly, particularly in light of our limited resources. Similarly, if we determine that third parties are infringing on our patents or other intellectual property rights, our limited resources may prevent us from litigating or otherwise taking actions to enforce our rights. Any such litigation or inability to enforce our rights could require us to change our business practices, hinder or prevent our ability to deliver our products and services, and result in a negative impact to our business. Expansion of our business via product line enhancements or new product lines to drive increased growth in current or new markets may be inhibited by the intellectual property rights of our competitors and/or suppliers. Our inability to successfully mitigate those factors may significantly reduce our market opportunity and subsequent growth. Any litigation that may be necessary in the future could result in substantial costs and diversion of resources and could have a material adverse effect on our business, financial condition, and operating results.

Risk Factors Relating to Regulation

Our business is subject to intense governmental regulation and scrutiny, both in the U.S. and abroad.

The production, marketing, and R&D of our products is subject to extensive regulation and review by the FDA and other governmental authorities both in the United States and abroad. In addition to testing and approval procedures, extensive regulations also govern marketing, manufacturing, distribution, labeling, and record keeping. If we do not comply with applicable regulatory requirements, violations could result in warning letters, non-approvals, suspensions of regulatory approvals, civil penalties and criminal fines, product seizures and recalls, operating restrictions, injunctions, and criminal prosecution.

Periodically, legislative or regulatory proposals are introduced that could alter the review and approval process relating to medical products. It is possible that the FDA will issue additional regulations further restricting the sale of our present or proposed products. Any change in legislation or regulations that governs the review and approval process relating to our current and future products could make it more difficult and costlier to obtain approval for new products, or to produce, market, and distribute existing products.

If the FDA begins to enforce regulation of our molecular diagnostic tests, we could incur substantial costs and delays associated with trying to obtain pre-market clearance or approval and costs associated with complying with post-market requirements.

Clinical laboratory tests like our molecular diagnostic tests are regulated under CLIA as well as by applicable state laws. Most Laboratory Developed Tests (“LDTs”) are currently not subject to the FDA’s regulation (although reagents, instruments, software, or components provided by third parties and used to perform LDTs may be subject to regulation). In October 2014, the FDA issued two draft guidance documents: “Framework for Regulatory Oversight of Laboratory Developed Tests”, which provides an overview of how the FDA would regulate LDTs through a risk-based approach, and “FDA Notification and Medical Device Reporting for Laboratory Developed Tests”, which provides guidance on how the FDA intends to collect information on existing LDTs, including adverse event reports. On January 13, 2017, the FDA also issued a discussion paper on LDTs. Pursuant to the Framework for Regulatory Oversight draft guidance, LDT manufacturers would be subject to medical device registration, listing, and adverse event reporting requirements. The risk-based classification considers the LDT’s intended use, technological characteristics, and the risk to patients if the LDT were to fail.

21

Pursuant to the Framework for Regulatory Oversight draft guidance, LDT manufacturers would be required to either submit a pre-market application and receive the FDA’s approval before an LDT may be marketed or submit a pre-market notification in advance of marketing. These requirements would be phased in, starting with higher risk LDTs, following the issuance of the FDA’s final guidance on this topic, which the FDA has identified as a priority. The draft guidance provides that LDTs that are already marketed at the time the final guidance is issued would not be withdrawn from the market during the FDA’s review process.

There is no timeframe within which the FDA must issue its final guidance, but issuance of this final guidance has been identified among a list of the FDA’s priorities. As of the date of this filing, the FDA has not issued its final guidance. In August 2020, however, the U.S. Department of Health and Human Services – the parent agency for FDA – announced that the FDA “will not require premarket review of LDTs absent notice-and-comment rulemaking, as opposed to through guidance documents, compliance manuals, website statements, or other informal issuances.” It is unclear at this time whether the Biden Administration will rescind or reverse this policy. It is also unclear at this time when, or if, the FDA will finalize its plans to end enforcement discretion (e.g., via notice and comment rulemaking or otherwise), and even then, the new regulatory requirements are expected to be phased‑in over time. Nevertheless, the FDA may attempt to regulate certain LDTs on a case‑by‑case basis at any time.

Legislative proposals addressing the FDA’s oversight of LDTs have been introduced in previous Congresses, and we expect that new legislative proposals will be introduced from time‑to‑time. The likelihood that Congress will pass such legislation and the extent to which such legislation may affect the FDA’s plans to regulate certain LDTs as medical devices is difficult to predict at this time. If the FDA ultimately regulates certain LDTs, whether via final guidance, final regulation, or as instructed by Congress, our molecular diagnostic tests may be subject to certain additional regulatory requirements. The cost of conducting clinical trials and otherwise developing data and information to support pre-market applications may be significant. If we are required to submit applications for our currently marketed tests, we may be required to conduct additional studies, which may be time-consuming and costly and could result in our currently marketed tests being withdrawn from the market. If our tests are allowed to remain on the market, but there is uncertainty in the marketplace about our tests, and if we are required by the FDA to label them investigational, or if labeling claims the FDA allows us to make are limited, orders may decline, and reimbursement may be adversely affected. Continued compliance with the FDA’s regulations would increase the cost of conducting our business, and subject us to heightened regulation by the FDA and penalties for failure to comply with these requirements.

In sum, we cannot predict the timing or form of any such guidance or regulation, or the potential effect on our existing molecular diagnostic tests or our tests in development, or the potential impact of such guidance or regulation on our business, financial condition, and results of operations.

If we fail to comply with Federal, State, and foreign laboratory licensing requirements, we could lose the ability to perform our tests or experience disruptions to our business.

We are subject to CLIA, a federal law that regulates clinical laboratories that perform testing on specimens derived from humans for the purpose of providing information for the diagnosis, prevention, or treatment of disease. CLIA regulations mandate specific standards in the areas of personnel qualifications, administration, and participation in proficiency testing, patient test management, and quality assurance. CLIA certification is also required in order for our business to be eligible to bill Federal and State healthcare programs, as well as many private third-party payors, for our molecular diagnostic tests. To renew these certifications, we are subject to survey and inspection every two years. Moreover, CLIA inspectors may make random inspections of our clinical reference laboratories. Pennsylvania laws also require that we maintain a license and establish standards for the day-to-day operation of our clinical reference laboratory in Pittsburgh, Pennsylvania. In addition, our Pittsburgh laboratory is required to be licensed on a test-specific basis by certain other states. If we were unable to obtain or lose our CLIA certificate or State licenses for our laboratories, whether as a result of revocation, suspension, or limitation, we would no longer be able to perform our molecular diagnostic tests, which could have a material adverse effect on our business, financial condition, and results of operations. If we were to lose our licenses issued by the States in which we are required to hold licenses, we would not be able to test specimens from those States. New molecular diagnostic tests we may develop may be subject to new approvals by governmental bodies, and we may not be able to offer our new molecular diagnostic tests to patients in such jurisdictions until such approvals are received.

22

Complying with numerous statutes and regulations pertaining to our molecular diagnostics business is an expensive and time-consuming process, and any failure to comply could result in substantial penalties.

We are subject to regulation by both the Federal government and the States in which we conduct our molecular diagnostics business, including:

● The Food, Drug, and Cosmetic Act, as supplemented by various other statutes;

● The Prescription Drug Marketing Act of 1987, the amendments thereto, and the regulations promulgated thereunder and contained in 21 C.F.R. Parts 203 and 205;

● CLIA and State licensing requirements;

● Manufacturing and promotion laws;

● Medicare and Medicaid billing and payment regulations applicable to clinical laboratories;

● The Federal Anti-Kickback Statute, which prohibits knowingly and willfully offering, paying, soliciting, or receiving remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual, or the furnishing, arranging for, or recommending of an item or service that is reimbursable, in whole or in part, by a federal healthcare program;

● The Federal Stark physician self-referral law (and state equivalents), which prohibits a physician from making a referral for certain designated health services covered by the Medicare program, including laboratory and pathology services, if the physician or an immediate family member has a financial relationship with the entity providing the designated health services, unless the financial relationship falls within an applicable exception to the prohibition;

● The Federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), which established comprehensive federal standards with respect to the privacy and security of protected health information and requirements for the use of certain standardized electronic transactions, and amendments made in 2013 to HIPAA under the Health Information Technology for Economic and Clinical Health Act, which strengthen and expand HIPAA privacy and security compliance requirements, increase penalties for violators, extend enforcement authority to state attorneys general, and impose requirements for breach notification;

● The Federal Civil Monetary Penalties Law, which prohibits, among other things, the offering or transfer of remuneration to a Medicare or state healthcare program beneficiary if the person knows or should know it is likely to influence the beneficiary’s selection of a particular provider, practitioner, or supplier of services reimbursable by Medicare or a state healthcare program, unless an exception applies;

● The Federal False Claims Act, which imposes liability on any person or entity that, among other things, knowingly presents, or causes to be presented, a false or fraudulent claim for payment to the federal government;

● Other Federal and State fraud and abuse laws, prohibitions on self-referral, fee-splitting restrictions, prohibitions on the provision of products at no or discounted cost to induce physician or patient adoption, and false claims acts, which may extend to services reimbursable by any third-party payor, including private insurers;

● The prohibition on reassignment of Medicare claims, which, subject to certain exceptions, precludes the reassignment of Medicare claims to any other party;

● The rules regarding billing for diagnostic tests reimbursable by the Medicare program, which prohibit a physician or other supplier from marking up the price of the technical component or professional component of a diagnostic test ordered by the physician or other supplier and supervised or performed by a physician who does not “share a practice” with the billing physician or supplier; and

● State laws that prohibit other specified practices related to billing such as billing physicians for testing that they order, waiving coinsurance, co-payments, deductibles, and other amounts owed by patients, and billing a State Medicaid program at a price that is higher than what is charged to other payors.

We have implemented policies and procedures designed to comply with these laws and regulations. We periodically conduct internal reviews of our compliance with these laws. Our compliance is also subject to governmental review. The growth of our business may increase the potential of violating these laws, regulations, or our internal policies and procedures. The risk that we are found in violation of these, or other laws and regulations is further increased by the fact that many have not been fully interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of interpretations. Violations of Federal or State regulations may incur investigation or enforcement action by the FDA, Department of Justice, State agencies, or other legal authorities, and may result in substantial civil, criminal, or other sanctions. Any action brought against us for violation of these or other laws or regulations, even if we successfully defend against it, could cause us to incur significant legal expenses and divert managements’ attention from the operation of our business. If our operations are found to be in violation of any of these laws and regulations, we may be subject to civil and criminal penalties, damages, and fines, we could be required to refund payments received by it, we could face possible exclusion from Medicare, Medicaid and other Federal or State healthcare programs, and we could even be required to cease operations. Any of the foregoing consequences could have a material adverse effect on our business, financial condition, and results of operations.

23

If we use hazardous materials in a manner that causes contamination or injury, we could be liable for resulting damages.

We are subject to Federal, State, and local laws, rules and regulations governing the use, discharge, storage, handling, and disposal of biological material, chemicals, and waste. We cannot eliminate the risk of accidental contamination or injury to employees or third parties from the use, storage, handling, or disposal of these materials. In the event of contamination or injury, we could be held liable for any resulting damages, remediation costs, and any related penalties or fines. This liability could exceed our resources or any applicable insurance coverage we may have. The cost of compliance with these laws and regulations may become significant, and our failure to comply may result in substantial fines or other consequences, and either could have a significant impact on our operating results.

The healthcare regulatory and political framework is uncertain and evolving.

Healthcare laws and regulations are rapidly evolving and may change significantly in the future, which could adversely affect our financial condition and results of operations. For example, in March 2010, the Patient Protection and Affordable Care Act, (“ACA”), was adopted, which is a healthcare reform measure that provided healthcare insurance for approximately 30 million additional Americans. The ACA includes a variety of healthcare reform provisions and requirements that became effective at varying times through 2018 and substantially changed the way healthcare is financed by both governmental and private insurers, which may significantly impact our industry and our business. For instance, the ACA requires “Applicable Manufacturers” to disclose to the Secretary of the Department of Health & Human Services drug sample distributions and certain payments or transfers of value to covered recipients (physicians and teaching hospitals) on an annual basis. “Applicable Manufacturers” and “Applicable Group Purchasing Organizations” must also disclose certain physician ownership or investment interests. The data submitted will ultimately be made available on a public website. Based upon the structure of our relationship with our clients, we may be included in the definition of “Applicable Manufacturer” for purposes of the disclosure requirements or may provide services that include the transfer of drug samples and/or other items of value to covered recipients. As such, we may be required to disclose or provide information that is subject to disclosure. There may be certain risks and penalties associated with the failure to properly make such disclosures, including but not limited to the specific civil liabilities set forth in the ACA, which allows for a maximum civil monetary penalty per “Applicable Manufacturer” of $1,150,000 per year. There may be additional risks and claims made by third parties derived from an improper disclosure that are difficult to ascertain at this time.

We cannot predict whether future healthcare initiatives will be implemented at the federal or state level, or how any future legislation or regulation may affect us. The U.S. Supreme Court is currently reviewing the constitutionality of the ACA, although it is unclear when a decision will be made. Further, it is possible that additional governmental action will be taken in response to the COVID-19 pandemic.

Risks Related to the Securities Markets and Ownership of Our Common Stock

Our certificate of incorporation, as amended, provides that, to the fullest extent permitted by law, the Court of Chancery of the State of Delaware will be the exclusive forum for certain legal actions between us and our stockholders, which could limit our stockholders’ ability to obtain a judicial forum viewed by the stockholders as more favorable for disputes with us or our directors, officers, or employees.

Our certificate of incorporation, as amended, provides that, to the fullest extent permitted by law, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (1) any derivative action or proceeding brought on behalf of the corporation, (2) any action asserting a claim of breach of a fiduciary duty owed by any director or officer of the corporation to the corporation or the corporation’s stockholders, (3) any action asserting a claim against the corporation arising pursuant to any provision of the General Corporation Law or the corporation’s Certificate of Incorporation or Bylaws, or (4) any action asserting a claim against the corporation governed by the internal affairs doctrine. This exclusive forum provision does not apply to suits brought to enforce a duty or liability created by the Securities Exchange Act of 1934. It could apply, however, to a suit that falls within one or more of the categories enumerated in the exclusive forum provision and asserts claims under the Securities Act, as amended, inasmuch as Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rule and regulations thereunder. There is uncertainty as to whether a court would enforce such provision with respect to claims under the Securities Act, and our stockholders will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder.

24

Any person or entity purchasing or otherwise acquiring any interest in any of our securities shall be deemed to have notice of and consented to these provisions. These exclusive-forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum of their choosing for disputes with us or our directors, officers, or other employees, which may discourage lawsuits against us and our directors, officers, and other employees.

If a court were to find the choice of forum provision contained in our certificate of incorporation, as amended, to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, results of operations, and financial condition. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.

Our common stock could be delisted from The NASDAQ Capital Market, which delisting could hinder your ability to obtain accurate quotations on the price of our common stock or dispose of our common stock in the secondary market.

On February 17, 2022, we received a letter from the Listing Qualifications Department (the “Staff”) of The NASDAQ Stock Market LLC (“NASDAQ”) informing the Company that because the closing bid price for the Company’s common stock listed on NASDAQ was below $1.00 for 30 consecutive trading days, the Company does not comply with the minimum closing bid price requirement for continued listing on The NASDAQ Capital Market under NASDAQ Marketplace Rule 5550(a)(2), requiring a minimum bid price of $1.00 per share (the “Minimum Bid Price Requirement”). The notification has no immediate effect on the listing of the Company’s common stock.

In accordance with NASDAQ’s Marketplace Rule 5810(c)(3)(A), the Company has a period of 180 calendar days, or until August 16, 2022, to regain compliance with the Minimum Bid Price Requirement. If at any time before August 16, 2022 the bid price of the Company’s common stock closes at or above $1.00 per share for a minimum of 10 consecutive business days, NASDAQ will provide written notification that the Company has achieved compliance with the Minimum Bid Price Requirement.

The letter also disclosed that in the event the Company does not regain compliance with the Minimum Bid Price Requirement by August 16, 2022, the Company may be eligible for additional time. To qualify for additional time, the Company would be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for The NASDAQ Capital Market, with the exception of the bid price requirement, and would need to provide written notice of its intention to cure the deficiency during the second compliance period, by effecting a reverse stock split, if necessary. However, if it appears to the Staff that the Company will not be able to cure the deficiency, or if the Company is otherwise not eligible, the Staff would notify the Company that its securities would be subject to delisting. In the event of such notification, the Company may appeal the Staff’s determination to delist its securities, but there can be no assurance the Staff would grant the Company’s request for continued listing.

25

The Company intends to continue actively monitoring the bid price for its common stock between now and August 16, 2022 and will consider available options to resolve the deficiency and regain compliance with the Minimum Bid Price Requirement.

In the event our common stock is delisted from The NASDAQ Capital Market and we are also unable to maintain listing on another alternate exchange, trading in our common stock could thereafter be conducted in FINRA’s OTC Bulletin Board or in the over-the-counter markets in the so-called pink sheets. In such event, the liquidity of our common stock would likely be impaired, not only in the number of shares which could be bought and sold, but also through delays in the timing of the transactions, and there would likely be a reduction in our coverage by security analysts and the news media, thereby resulting in lower prices for our common stock than might otherwise prevail.

Limitations on director and officer liability and indemnification of our officers and directors by us may discourage stockholders from bringing a suit against a director.

Our Certificate of Incorporation and Bylaws provide, with certain exceptions as permitted by governing state law, that a director or officer shall not be personally liable to us or our stockholders for breach of fiduciary duty as a Director, except for acts or omissions which involve intentional misconduct, fraud, knowing violation of law, or unlawful payments of dividends. These provisions may discourage stockholders from bringing a suit against a director for breach of fiduciary duty and may reduce the likelihood of derivative litigation brought by stockholders on our behalf against a director. In addition, our certificate of incorporation and bylaws may provide for mandatory indemnification of directors and officers to the fullest extent permitted by governing state law.

We do not expect to pay dividends for the foreseeable future, and we may never pay dividends; investors must rely on stock appreciation, if any, for any return on investment in our common stock.

We currently intend to retain any future earnings to support the development and expansion of our business and do not anticipate paying cash dividends in the foreseeable future. Our payment of any future dividends will be at the discretion of our Board of Directors after taking into account various factors, including but not limited to, our financial condition, operating results, cash needs, growth plans, and the terms of any credit agreements that we may be a party to at the time. In addition, our ability to pay dividends on our common stock may be limited by state law. Accordingly, investors must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize certain returns on their investment. As a result, investors must rely on stock appreciation and a liquid trading market for any return on investment in our common stock.

Our Board of Directors’ ability to issue undesignated preferred stock and the existence of anti-takeover provisions may depress the value of our common stock.

Our authorized capital includes 20 million shares of preferred stock. Of this amount and 79,246 shares have been designated as series B convertible preferred stock and the remaining authorized shares are undesignated preferred stock. Our Board of Directors has the power to issue any or all of the shares of undesignated preferred stock, including the authority to establish one or more series and to fix the powers, preferences, rights, and limitations of such class or series, without seeking stockholder approval. Further, as a Delaware corporation, we are subject to provisions of the Delaware General Corporation Law regarding business combinations. We may, in the future, consider adopting additional anti-takeover measures. The authority of our Board of Directors to issue undesignated stock and the anti-takeover provisions of Delaware law, as well as any future anti-takeover measures adopted by us, may, in certain circumstances, delay, deter, or prevent takeover attempts and other changes in control not approved by our Board of Directors. As a result, our stockholders may lose opportunities to dispose of their shares at favorable prices generally available in takeover attempts or that may be available under a merger proposal and the market price, voting, and other rights of the holders of common stock may also be affected.

26

General Risk Factors

Our success is dependent on our ability to attract and retain technical personnel, sales and marketing personnel, and other skilled management.

Our success depends to a significant degree on our ability to attract, retain, and motivate highly skilled and qualified personnel. Failure to attract and retain necessary technical, sales and marketing personnel, and skilled management could adversely affect our business. If we fail to attract, train, and retain sufficient numbers of these highly qualified people, our business, financial condition, and results of operations could be materially and adversely affected.

Our ability to use net operating loss and tax credit carryforwards and certain built-in losses to reduce future tax payments is limited by provisions of the Internal Revenue Code and may be subject to further limitation because of prior or future offerings of our stock or other transactions.

Sections 382 and 383 of the United States Internal Revenue Code of 1986, as amended (the “Code”) contain rules that limit the ability of a company that undergoes an ownership change, which is generally an increase in the ownership percentage of certain stockholders in the stock of a company by more than 50% over a three-year period, to utilize its net operating loss and tax credit carryforwards and certain built-in losses recognized in years after the ownership change. These rules generally operate by focusing on ownership changes involving stockholders owning directly or indirectly 5% or more of the stock of a company and any change in ownership arising from a new issuance of stock by that company. Generally, if an ownership change, as defined by Section 382 of the Code, occurs, the yearly taxable income limitation on the use of net operating loss and tax credit carryforwards and certain built-in losses is equal to the product of the applicable long-term tax-exempt rate and the value of stock immediately before the ownership change. We have not assessed the potential impact of Sections 382 and 383.

Costs incurred because we are a public company may affect our profitability.

As a public company, we incur significant legal, accounting, and other expenses and are subject to the SEC’s rules and regulations relating to public disclosure that generally involve a substantial expenditure of financial resources.  In addition, the Sarbanes-Oxley Act of 2002, as well as rules subsequently implemented by the SEC, require changes in corporate governance practices of public companies. Full compliance with such rules and regulations requires significant legal and financial compliance costs and makes some activities more time-consuming and costlier, which may negatively impact our financial results. To the extent our earnings suffer as a result of the financial impact of our SEC reporting or compliance costs, our ability to develop an active trading market for our securities could be harmed.

Shares eligible for future sale may adversely affect the market.

From time to time, certain stockholders may be eligible to sell some or all of their shares of common stock pursuant to Rule 144, promulgated under the Securities Act subject to certain limitations. In general, pursuant to Rule 144 as in effect as of the date of this filing, a stockholder (or stockholders whose shares are aggregated) who has satisfied the applicable holding period and is not deemed to have been one of our affiliates at the time of sale, or at any time during the three months preceding a sale, may sell their shares of common stock. Any substantial sale, or cumulative sales, of our common stock pursuant to Rule 144 or pursuant to any resale prospectus may have a material adverse effect on the market price of our securities.

We expect volatility in the price of our common stock, which may subject us to securities litigation.

The market for our common stock may be characterized by significant price volatility when compared to seasoned issuers, and we expect that our share price will be more volatile than a seasoned issuer for the indefinite future. In the past, plaintiffs have often initiated securities class action litigation against companies following periods of volatility in the market price of their securities. We may in the future be the target of similar litigation. Securities litigation could result in substantial costs and liabilities and could divert management’s attention and resources.

Acquisitions involve risks that could result in adverse changes to operating results, cash flows, and liquidity.

We may desire to make strategic acquisitions in the future. However, we may not be able to identify suitable acquisition opportunities, or we may be unable to obtain the consent of our stockholders and therefore, may not be able to complete such acquisitions. We may pay for acquisitions with our common stock or with convertible securities, which may dilute shareholders’ investment in our common stock, or we may decide to pursue acquisitions that our investors may not agree with. In connection with potential acquisitions, we may agree to substantial earn-out arrangements. To the extent we defer the payment of the purchase price for any acquisition through a cash earn-out arrangement, cash flows will be reduced in subsequent periods.

27

In addition, acquisitions, including our recent acquisition of zPREDICTA, Inc. may expose us to operational challenges and risks, including:

● the ability to profitably manage acquired businesses or successfully integrate the operations of acquired businesses, as well as the acquired business’s financial reporting and accounting control systems into our existing platforms;

● ​increased indebtedness and contingent purchase price obligations associated with an acquisition;

● ​the ability to fund cash flow shortages that may occur if anticipated revenue is not realized or is delayed, whether by general economic or market conditions, or unforeseen internal difficulties;

● ​the availability of funding sufficient to meet increased capital needs;

● ​diversion of management’s time and attention from existing operations; and

● ​the ability to retain or hire qualified personnel required for expanded operations.

Completing acquisitions may require significant management time and financial resources because we may need to assimilate widely dispersed operations with different corporate cultures. In addition, acquired companies may have liabilities that we failed to or were unable to discover in the course of performing due diligence investigations. We cannot assure the shareholders’ that the indemnification granted by sellers of acquired companies will be sufficient in amount, scope, or duration to fully offset the possible liabilities associated with businesses or properties we assume upon consummation of an acquisition. We may learn additional information about our acquired businesses that could have a material adverse effect on us, such as unknown or contingent liabilities and liabilities related to compliance with applicable laws. Any such liabilities, individually or in the aggregate, could have a material adverse effect on our business. Failure to successfully manage the operational challenges and risks associated with, or resulting from, acquisitions could adversely affect our results of operations, cash flows, and liquidity. Borrowings or issuances of convertible securities associated with these acquisitions may also result in higher levels of indebtedness, which could adversely impact our ability to service our debt within the scheduled repayment terms.

Security breaches, loss of data and other disruptions to our business or the business of our third-party service providers could compromise sensitive information related to our business or prevent us from accessing critical information and expose us to liability, which could adversely affect our business and reputation.

Our business requires that we collect and store sensitive data, including protected health and credit card information and proprietary business and financial information. We face a number of risks relative to the protection of, and the service providers’ protection of, this critical information, including loss of access, inappropriate disclosure, and inappropriate access, as well as risks associated with our ability to identify and audit such events. The secure processing, storage, maintenance, and transmission of this critical information are vital to our operations and business strategy, and we devote significant resources to protecting such information. Although we take measures to protect sensitive information from unauthorized access or disclosure, our information technology and infrastructure may be vulnerable to attacks by hackers or viruses or otherwise breached due to employee error, malfeasance, or other activities. While we have not experienced any such attack or breach, if such event would occur and cause interruptions in our operations, our networks could be compromised and the information we store on those networks could be accessed by unauthorized parties, publicly disclosed, lost, or stolen. Unauthorized access, loss, or dissemination could disrupt our operations, including collecting, processing, and preparing company financial information, managing the administrative aspects of our business, and damaging our reputation, any of which could adversely affect our business. In addition, the interpretation and application of consumer, health-related, and data protection laws in the United States are often uncertain, contradictory, and in flux. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our practices. If so, this could result in government-imposed fines or orders requiring that we change our practices, which could adversely affect our business. Complying with these various laws could cause us to incur substantial costs or require us to change our business practices, systems, and compliance procedures in a manner adverse to our business. Additionally, in connection with the ongoing COVID-19 pandemic, many of our employees have the ability to work remotely, which may increase the risk of security breaches, loss of data, and other disruptions as a consequence of more employees accessing sensitive and critical information from remote locations.

28

If we are unable to prevent such security breaches or privacy violations or implement satisfactory remedial measures in connection with security incidents, we may suffer loss of reputation, financial loss, and civil or criminal fines or other penalties. In addition, these breaches and other forms of inappropriate access can be difficult to detect, and any delay in identifying them may lead to increased harm of the type described above.

If our information technology and communications systems fail or we experience a significant interruption in our operation, our reputation, business, and results of operations could be materially and adversely affected.

The efficient operation of our business is dependent on information technology and communications systems. The failure of these systems to operate as anticipated could disrupt our business and result in decreased revenue and increased overhead costs. In addition, we do not have complete redundancy for all of our systems and our disaster recovery planning cannot account for all eventualities. Our information technology and communications systems, including the information technology systems and services that are maintained by third-party vendors, are vulnerable to damage or interruption from natural disasters, fire, terrorist attacks, malicious attacks by computer viruses or hackers, and power loss or failure of computer systems, Internet, telecommunications or data networks. If these systems or services become unavailable or suffer a security breach, we may expend significant resources to address these problems, and our reputation, business, and results of operations could be materially and adversely affected.

Overview

We operate in four primary business areas: first, the application of artificial intelligence (“AI”) in our precision medicine business, to provide AI-driven predictive models of tumor drug response to improve clinical outcomes for patients and to assist pharmaceutical, diagnostic, and biotech industries in the development of new personalized drugs and diagnostics; second, creation of tumor-specific 3D cell culture models driving accurate prediction of clinical outcomes; third, contract services and research focused on solubility improvements, stability studies, and protein production and; fourth, production of the United States Food and Drug Administration (“FDA”)-cleared STREAMWAY System for automated, direct-to-drain medical fluid disposal and associated products

We have four reportable segments: Helomics®, zPREDICTA®, Soluble^TM and Skyline®. The Helomics segment includes clinical testing and contract research services that include the application of AI. Our zPREDICTA segment specializes in organ-specific disease models that provide 3D reconstruction of human tissues accurately representing each disease state and mimicking drug response enabling accurate testing of anticancer agents. Our Soluble segment provides services using a self-contained, automated system that conducts high-throughput, self-interaction chromatography screens, using additives and excipients commonly included in protein formulations resulting in soluble and physically stable formulations for biologics. Our Skyline segment consists of the STREAMWAY System product sales, and our TumorGenesis subsidiary is included within corporate. Going forward, we have determined that we will focus our resources on the Helomics and zPREDICTA segments and our primary mission statements to accelerate patient-centric drug discovery to improve patient outcomes in cancer treatment, harnessing the power of AI, and to develop tumor-specific 3D cell culture models that provide accurate 3D reconstruction of human tissues representing each cancer disease state.

Capital Requirements

Since inception, we have been unprofitable. We incurred net losses of $19,657,174 and $25,884,397 for the years ended December 31, 2021, and December 31, 2020, respectively. As of December 31, 2021, and December 31, 2020, we had an accumulated deficit of $128,040,282 and $108,383,108, respectively.

We have never generated sufficient revenues to fund our capital requirements. Since 2017, we have diversified our business by investing in ventures, including making significant loans and investments in early-stage companies. These activities led to the acquisition of Helomics in April 2019, the purchase of the assets of two businesses in 2020 and the acquisition of zPREDICTA in November 2021, each of which have accelerated our capital needs. We have funded our operations through a variety of debt and equity instruments. See “Liquidity and Capital Resources – Liquidity and Plan of Financing” and “Liquidity and Capital Resources – Financing Transactions” below.

Our future cash requirements and the adequacy of available funds depend on our ability to generate revenues from our Helomics and zPREDICTA segments; our ability to continue to sell our Skyline Medical products and to reach profitability in the Skyline Medical business, our ability to generate revenue from our Soluble reportable segment and the availability of future financing to fulfill our business plans. See “Liquidity and Capital Resources – Liquidity and Plan of Financing” below.

Our limited history of operations, especially in our precision medicine business, and our change in the emphasis of our business, starting in 2017, makes prediction of future operating results difficult. We believe that period-to-period comparisons of our operating results should not be relied on as predictive of our future results.

Results of Operations

Comparison of Year Ended December 31, 2021 with Year Ended December 31, 2020

	2021		2020		Difference
Revenue	$	1,420,680	$	1,252,272	$	168,408
Cost of goods sold		487,024		447,192		(39,832	)
General and administrative expense		10,932,125		10,351,973		(580,152	)
Operations expense		2,698,565		2,351,709		(346,856	)
Sales and marketing expense		774,530		584,937		(189,593	)

Revenue. We recorded revenue of $1,420,680 in 2021, compared to $1,252,272 in 2020. Our Skyline division was responsible for the majority of the revenue, with Soluble generating $233,293 and $2,870 and Helomics generating $13,367 and $64,188 in revenue in the years ended December 31, 2021 and 2020, respectively. We sold 15 STREAMWAY System units in 2021 and 25 STREAMWAY System units in 2020.

Cost of sales. Cost of sales was $487,024 and $447,192 in 2021 and 2020, respectively. The increase in cost of sales is primarily due to increased cost of disposables and costs associated with our repair and maintenance contracts The gross profit margin was 66% in 2021 compared to 64% in 2020. Our margins increased in 2021 due to higher margins associated with our Soluble operating segment and from our Skyline Medical operating segment disposable product margins.

32

General and Administrative expense. General and administrative (“G&A”) expense primarily consists of management salaries, professional fees, consulting fees, travel expense, administrative fees and general office expenses.

G&A expense increased by $580,152 to $10,932,125 in 2021 from $10,351,973 in 2020. The increase was primarily due to increases in staff related expenses including additional headcount, as well as certain one-time expenses related to severance incurred as part of the departure of our former CEO. Additional increases included higher costs for consulting expenses and fees to our Board of Directors. Also, increased depreciation was driven by newly added assets supporting our Helomics division. These increases were offset by lower share-based compensation and lower costs for investor relations.

Operations expense. Operations expense in our current stage primarily consists of expenses related to product development, prototyping and testing including staff related expenses for individuals performing this work.

Operations expense increased by $346,856 to $2,698,565 in 2021 compared to $2,351,709 in 2020. The increase in operations expense in 2021 was primarily due to higher payroll costs and higher costs associated with cloud computing, offset by decreased costs associated with consulting.

Sales and marketing expense. Sales and marketing expense consists of expenses required to sell products through independent reps, attendance at trade shows, product literature and other sales and marketing activities.

Sales and marketing expenses increased by $189,593 to $774,530 in 2021 compared to $584,937 in 2020. The increase in 2021 was due to increased expenses in web development, public relations, and market research.

Loss on goodwill impairment. We incurred a loss on impairment of goodwill of $2,813,792 and $12,876,498 during 2021 and 2020, respectively, all relating to the goodwill acquired in the Helomics acquisition in 2019. Our goodwill, for our Helomics operating segment, following the impairment was $0 and $2,813,792 at December 31, 2021 and December 31, 2020, respectively. The cumulative losses on goodwill are $23,790,290 as of December 31, 2021. See Note 10 to our audited consolidated financial statements included in this annual report.

Loss on intangible asset impairment. We incurred a loss on impairment of intangibles of $2,893,548 during the year ended December 31, 2021. The impairment recorded relates to the intangible assets of our Helomics operating segment and none of the Company’s other operating segments. The value of the intangible assets of the Helomics operating segment following the impairment was $0 at December 31, 2021. See Note 10 to our audited consolidated financial statements included in this annual report.

Loss on impairment of acquired software. We incurred a loss on impairment on acquired software of $1,249,727 during the year ended December 31, 2021. The impairment recorded relates to the acquired software asset of our Helomics operating segment and none of the Company’s other operating segments. The value of the acquired software asset of the Helomics operating segment following the impairment was $0 at December 31, 2021. Please see Note 10 to our audited consolidated financial statements included in this annual report for further information.

Other income. We earned other income of $184,528 in 2021 compared to $843,440 in 2020. Other income included interest income and gains on settlement of outstanding payables during 2021. Other income was comprised of gain on the forgiveness of the Paycheck Protection Program loan of $541,867 and gains on settlement of outstanding payables during 2020.

Other expense. We incurred other expenses of $239,631 in 2021 compared to $2,427,026 in 2020. Other expenses consisted primarily of interest expense, payment penalties and amortization of original issue discounts.

Gain on derivative instruments. We incurred a gain of $164,902 in 2021 compared to a gain of $1,765,907 in 2020, primarily related to the changes in fair market value on derivatives.

Gain on notes receivable associated with asset purchase. We recorded a gain of $1,290,000 in 2020 related to the gain on notes receivable in connection with our acquisition of certain assets in 2020.

33

Income Taxes. We recognized $661,658 income tax benefit in our consolidated statement of net loss in the year ended December 31, 2021 related to the release of the valuation allowance following the zPREDICTA acquisition and zero related to our U.S. operating losses, as all tax benefits are fully reserved.

Liquidity and Capital Resources

Cash Flows

Net cash used in operating activities was $12,208,929 in 2021, compared with net cash used of $12,257,732 in 2020. Cash used in operating activities increased in 2021 primarily due to operating losses as well as outflows related to payments on accounts payables and payments for accrued expenses, inventories and prepaid expenses.

Cash flows used in investing activities were $10,607,536 in 2021, and $167,456 in 2020. Cash flows used in investing activities in 2021 were primarily related to the acquisition of our zPREDICTA subsidiary in the amount of $9,590,214 and $910,429 of cash outflows related to purchases of fixed assets. Cash flows used in investing activities in 2020 were primarily for purchases of fixed assets, offset by disposals of fixed assets.

Net cash provided by financing activities was $50,340,748 in 2021 compared to net cash provided of $12,952,689 in 2020. Cash flows provided by financing activities in 2021 were primarily due from proceeds from the issuance of common stock and warrants of $50,523,527 in several equity offerings and proceeds from the exercise of warrants into common stock of $4,513,871, offset by repayment of debt and payment penalties of $5,236,214.

Liquidity and Plan of Financing

Since our inception, we have incurred significant losses, and our accumulated deficit was $128,040,282 as of December 31, 2021. We have committed significant capital and management resources to develop our CRO business and other new business areas and intend to continue to devote significant resources to the Helomics and zPREDICTA business and other new business in this market. Our business will need to generate significantly more revenue to sufficiently fund our operations without external financing. Our operations from inception have been funded with private placements of convertible debt securities and equity securities, public offerings, and loan agreements. We have not achieved profitability and anticipate that we will continue to incur net losses at least through the remainder of 2022. We had revenues of $1,420,680 and $1,252,272 in 2021 and 2020, respectively, but we had negative operating cash flows of $12,208,929 and $12,257,732 in 2021 and 2020, respectively. Our cash balance was $28,202,615 as of December 31, 2021, and our accounts payable and accrued expenses were an aggregate $2,284,415. See “Financing Transactions” below.

We believe that our existing capital resources will be sufficient to support our operating plan for the next twelve months and beyond. However, we may also seek to raise additional capital to support our growth through additional debt, equity or other alternatives or a combination thereof. We would raise such capital through equity or debt financing to fund our capital and equipment investments and our operations.

Financing Transactions

We have funded our operations through a combination of debt and equity instruments including an early bank loan (since repaid), and a variety of debt and equity offerings. Since late 2018, these financing transactions have consisted of (1) secured convertible notes to private investors starting in late 2018, the remaining amount of which was repaid on March 1, 2021; (2) a series of loans from Dr. Carl Schwartz, our former CEO, starting in late 2018, which were exchanged for common stock in 2020; and (3) a number of public offerings, registered direct offerings and private placements, including an equity line arrangement (offerings), since 2019.

2021 Offerings

In January and February 2021, the Company completed a series of five offerings, all of which were priced at-the-market under applicable NASDAQ rules. The first four offerings were registered direct offerings of common stock under its shelf registration statement, and in each such case, in a concurrent private placement, the Company also issued such investors one warrant to purchase common stock for each two shares purchased in the transaction. Following those four offerings, the Company completed a private placement of common stock, with each investor receiving one warrant to purchase common stock for each two shares purchased in the transaction. In June 2021, the Company completed a registered direct offering of common stock and warrants. The warrants became exercisable on the effective date of an increase in the number of shares of the Company’s authorized common stock, which occurred on August 17, 2021, and expire three years after the initial exercise date. In each case, each such investor warrant is exercisable immediately upon issuance and will expire five and one-half years from the issue date. In each case, the Company paid to the placement agent an aggregate fee equal to 7.5% of the aggregate gross proceeds received by the Company in the offering and a management fee equal to 1% of the aggregate gross proceeds received by the Company in the offering and reimbursed the placement agent for certain non-accountable and out-of-pocket expenses. In addition, the Company granted to the placement agent, or its assigns warrants to purchase 7.5% of the shares sold to investors in the offering at an exercise price equal to 125% of the price of the shares in the transaction, with a term of five years for the registered direct offerings (three years for the June 2021 offering) or five and one-half years for the private placement.

These 2021 offerings were as follows:

Equity Line

On October 24, 2019, the Company entered into an equity purchase agreement with an investor, providing for an equity financing facility. Upon the terms and subject to the conditions in the purchase agreement, the investor is committed to purchase shares having an aggregate value of up to $15,000,000 of the Company’s common stock for a period of up to three years. The Company issued to the investor 104,651 commitment shares at a fair market value of $450,000 for entering into the agreement. From time to time during the three-year commitment period, provided that the closing conditions are satisfied, the Company may provide the investor with put notices to purchase a specified number of shares subject to certain limitations and conditions and at specified prices, which generally represent discounts to the market price of the common stock. As of December 31, 2021, there was $9,113,829 of remaining available balance under the equity line, subject to shareholder approval required for additional purchases, as well as requirements for market conditions including trading volume and stock price, and subject to other limitations. During the year ended December 31, 2021, the Company issued 647,504, shares of its common stock valued at $675,590 pursuant to the equity line.

Dr. Schwartz Notes

In November 2018, Dr. Schwartz made a loan to the Company with a principal balance of $370,000. As of December 31, 2018, one promissory note was held with a principal balance of $370,000 and an unamortized discount of $63,028. From November 30, 2018 through July 15, 2019, Dr. Schwartz made numerous loans to the Company in the total amount of $1,920,000 under two promissory notes. As consideration for these amounts, Dr. Schwartz received promissory notes and warrants to purchase 22,129 shares of the Company’s common stock at $8.36 per share. Further, beginning on February 1, 2019 and the first day of each calendar month thereafter while the note remained outstanding, a number of additional warrants were issued. Beginning in October 2019, the Company and Dr Schwartz began to renegotiate the note. Due to the negotiations, the Company did not issue any additional warrants because they would be cancelled under the new deal.

During January 2020, the Company entered into an exchange agreement with Dr. Schwartz. Under the exchange agreement, the two outstanding notes were cancelled and in exchange a new combined promissory note in the amount of $2,115,000 (the “2020 Schwartz Note”) bearing 12% interest per annum and maturing on September 30, 2020 was issued. In addition to the 2020 Schwartz Note, Dr. Schwartz received 50,000 shares of the Company’s common stock. All warrants issued under the prior promissory notes were cancelled under the exchange agreement; no rights and obligations remain under the cancelled notes. The Company determined that the exchange agreement had, in substance, occurred at December 31, 2019.

Effective as of April 21, 2020, the Company and Dr. Schwartz, entered into an exchange agreement relating to the 2020 Schwartz Note. The 2020 Schwartz Note bore twelve percent (12%) interest per annum and had a maturity date of September 30, 2020. The accrued interest on the note through April 21, 2020 was $77,878, resulting in a total balance of $2,192,878 in principal and accrued interest on the 2020 Schwartz Note as of such date. Dr. Schwartz and the Company agreed to exchange the 2020 Schwartz Note for newly issued shares of common stock of the Company at market value. Pursuant to the exchange agreement, Dr. Schwartz was issued 1,533,481 shares of newly issued common stock at an exchange rate of $1.43 per share, equal to the closing price of the common stock on April 21, 2020. In 2021, the Company determined that due to a calculation error, the balance of the 2020 Schwartz Note should have been higher by $143,573 at the time of the exchange agreement, and on February 24, 2021, the Company issued an additional 100,401 shares to Dr. Schwartz.

2020 Paycheck Protection Program Loan and Forgiveness

On April 20, 2020, the Company entered into a promissory note with Park State Bank, which provides for an unsecured loan of $541,867 pursuant to the Paycheck Protection Program (the “PPP”) under the Coronavirus Aid, Relief, and Economic Security Act and applicable regulations (the “CARES Act”). The promissory note has a term of 2 years with a 1% per annum interest rate. Payments are deferred for 6 months from the date of the promissory note and the Company can apply for forgiveness of all or a portion of the promissory note after 60 days for covered use of funds.

Pursuant to the terms of the PPP, the promissory note, or a portion thereof, may be forgiven if proceeds are used for qualifying expenses as described in the CARES Act, such as payroll costs, costs used to continue group health care benefits, mortgage interest payments, rent and utilities. The Company has used all proceeds for qualifying expenses. The Company received forgiveness for the loan under the Paycheck Protection Program and recognized a gain in other income for the full amount of the loan during the fourth quarter of 2020.

Issuances of Securities in Acquisitions

On April 4, 2019, the Company completed a forward triangular merger with Helomics Acquisition Inc., a wholly-owned subsidiary of the Company and Helomics, acquiring the remaining 75% of the capital stock of Helomics not already held by the Company. Upon the acquisition, all outstanding shares of Helomics stock not already held by the Company were converted into the right to receive a proportionate share of 400,000 shares of common stock and 3,500,000 shares of Series D convertible preferred stock of the Company. On April 4, 2020, the 3,500,000 shares of Series D convertible preferred stock were converted into 350,004 shares of common stock. Also, on April 4, 2019, the Company completed an exchange offer with the holders of certain notes and warrants of Helomics, in which the Company issued 863,732 shares of common stock to the noteholders in exchange for their notes and issued warrants to purchase up to 1,425,506 shares of common stock of the Company at an exercise price of $10.00 per share in exchange for the Helomics warrants held by the noteholders. An additional 59,700 Company warrants at an exercise price of $0.10 per share were exchanged for Helomics warrants held by other parties. On September 14, 2020, the Company agreed to amend the 1,425,506 Company warrants that were originally exercisable at $10.00 per share to allow the holders to exercise the warrants at an exercise price of $0.845 per share, equal to the then-current market value of the common stock.

On May 27, 2020, the Company entered into an Asset Purchase Agreement with InventaBioTech, Inc. (“InventaBioTech”) and two of its subsidiaries, Soluble Therapeutics, Inc. (“Soluble”), and BioDtech, Inc. (“BioDtech”), and simultaneously completed the acquisition of substantially all of Soluble’s and BioDtech’s assets. In exchange, the Company issued 125,000 shares of common stock and waived all existing claims that the Company has or may have against InventaBioTech (f/k/a CytoBioscience, Inc.), including the nonpayment of $1,290,000 owed by InventaBioTech to the Company. See Note 5 to the Consolidated Financial Statements.

On July 1, 2020, the Company entered into an Asset Purchase Agreement with Quantitative Medicine LLC (“Seller”), a Delaware limited liability company and its owners and simultaneously completed the acquisition of substantially all of the assets owned by Seller. Quantitative Medicine is a biomedical analytics and computational biology company that developed a novel, computational drug discovery platform called CoRE. CoRE is designed to dramatically reduce the time, cost, and financial risk of discovering new therapeutic drugs by predicting the main effects of drugs on target molecules that mediate disease. In exchange for Seller’s assets, including CoRE, the Company provided consideration in the form of 954,719 shares of common stock, which, when issued, had a fair value of $1,470,267. One half of the shares issued, or 477,359 shares were deposited and held in escrow upon issuance, while 207,144 of the remaining shares were issued to Carnegie Mellon University (“CMU”) in satisfaction of all pre-closing amounts owed to CMU under a technology licensing agreement that was assumed by the Company on the closing date. Half of the shares held in escrow will be released on the six-month anniversary of the closing date, and the other half will be released on the one-year anniversary of the closing date; provided, however, that all or some of the escrow shares may be released and returned to the Company for reimbursement in the event that the Company suffers a loss against which the Selling Parties have indemnified the Company pursuant to the Agreement. See Note 5 to the Consolidated Financial Statements.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations are based upon our audited consolidated Financial Statements, which have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“U.S. GAAP”). The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of our financial statements, the reported amounts of revenues and expenses during the reporting periods presented, as well as our disclosures of contingent assets and liabilities. On an on-going basis, we evaluate our estimates and assumptions, including, but not limited to, fair value of stock-based compensation, fair value of acquired intangible assets and goodwill, useful lives of intangible assets and fixed assets and income taxes.

We base our estimates and assumptions on our historical experience and on various other information available to us at the time that these estimates and assumptions are made. We believe that these estimates and assumptions are reasonable under the circumstances and form the basis for our making judgments about the carrying values of our assets and liabilities that are not readily apparent from other sources.  Actual results and outcomes could differ from our estimates primarily due to incorrect sales forecasting. We utilize a pipeline generated by our sales team and speak directly with all departments regarding estimates and assumptions. If, for any reason, those estimates, and assumptions vary substantially it would also impact our cost of goods and associated operating expenses. The other volatile area for estimates and assumptions is determining financing needs. Depending on how we choose to fund will affect numerous expense categories so the potential for underestimating those expenses is a viable concern.

Our significant accounting policies are described in “Note 1 – Summary of Significant Accounting Policies,” in Notes to audited consolidated Financial Statements of this Annual Report on Form 10-K. We believe that the following discussion addresses our critical accounting policies and reflects those areas that require more significant judgments and use of estimates and assumptions in the preparation of our audited consolidated Financial Statements.

Revenue Recognition.  We recognize revenue in accordance with ASC 606, Revenue Recognition.

Effective January 1, 2018, we adopted Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The standard’s core principle is that an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

Revenue from Product Sales. We have medical device revenue consisting primarily of sales of the STREAMWAY System, as well as sales of the proprietary cleaning fluid and filters for use with the STREAMWAY System. This revenue stream is reported within both the domestic and international revenue segments. We sell our medical device products directly to hospitals and other medical facilities using employed sales representatives and independent contractors. Purchase orders, which are governed by sales agreements in all cases, state the final terms for unit price, quantity, shipping and payment terms. The unit price is considered the observable stand-alone selling price for the arrangements. Our sales agreement, Terms and Conditions, is a dually executed contract providing explicit criteria supporting the sale of the STREAMWAY System. We consider the combination of a purchase order and acceptance of our Terms and Conditions to be a customer’s contract in all cases.

Product sales for medical devices consist of a single performance obligation that we satisfy at a point in time. We recognize product revenue when the following events have occurred: (1) we have transferred physical possession of the products, (2) we have a present right to payment, (3) the customer has legal title to the products, and (d) the customer bears significant risks and rewards of ownership of the products. Based on the shipping terms specified in the sales agreements and purchase orders, these criteria are generally met when the products are shipped from our facilities (“FOB origin,” which is our standard shipping terms). As a result, we determined that the customer is able to direct the use of, and obtain substantially all of the benefits from, the products at the time the products are shipped. We may, at our discretion, negotiate different shipping terms with customers which may affect the timing of revenue recognition. Our standard payment terms for customers are generally 30 to 60 days after we transfer control of the product to the customer. We allow returns of defective disposable merchandise if the customer requests a return merchandise authorization from us.

39

Customers may also purchase a maintenance plan for the medical devices from us, which requires us to service the STREAMWAY System for a period of one year subsequent to the one-year anniversary date of the original STREAMWAY System invoice. The maintenance plan is considered a separate performance obligation from the product sale, is charged separately from the product sale, and is recognized over time (ratably over the one-year period) as maintenance services are earned and provided. A time-elapsed output method is used to measure progress because we transfer control evenly by providing a stand-ready service. We have determined that this method provides a faithful depiction of the transfer of services to our customers.

All amounts billed to a customer in a sales transaction for medical devices related to shipping and handling, if any, represent revenues earned for the goods provided, and these amounts have been included in revenue. Costs related to such shipping and handling billing are classified as cost of goods sold.

Revenue from Clinical Testing. Clinic diagnostic testing is comprised of our Tumor Drug Response Testing (ChemoFx) and Genomic Profiling (BioSpeciFx) tests. The Tumor Drug Response Testing test determines how a patient’s tumor specimen reacts to a panel of various chemotherapy drugs, while the Genomic Profiling test evaluates the expression and/or status of a particular gene related to a patient’s tumor specimen. Revenues are recognized when control of the promised goods or services is transferred to customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. The estimated uncollectible amounts are generally considered implicit price concessions that are a reduction in revenue. Payments terms vary for contracts and services sold by our Helomics subsidiary. Our performance obligations are satisfied at one point in time when test reports are delivered, and studies are completed.

For service revenues, we estimate the transaction price which is the amount of consideration we expect to be entitled to receive in exchange for providing services based on our historical collection experience using a portfolio approach as a practical expedient to account for patient contracts as collective groups rather than individually. We monitor our estimates of transaction price to depict conditions that exist at each reporting date. If we subsequently determine that we will collect more consideration than we originally estimated for a contract with a patient, we will account for the change as an increase to the estimate of the transaction price, provided that such downward adjustment does not result in a significant reversal of cumulative revenue recognized.

We recognize revenue from these patients when contracts as defined in ASC 606, Revenue from Contracts with Customers are established at the amount of consideration to which we expect to be entitled or when we receive substantially all of the consideration subsequent to the performance obligations being satisfied.

CRO Revenue. Contract revenues are generally derived from studies conducted with biopharmaceutical and pharmaceutical companies. The specific methodology for revenue recognition is determined on a case-by-case basis according to the facts and circumstances applicable to a given contract. We typically use an input method that recognizes revenue based on our efforts to satisfy the performance obligation relative to the total expected inputs to the satisfaction of that performance obligation. For contracts with multiple performance obligations, we allocate the contract’s transaction price to each performance obligation on the basis of the standalone-selling price of each distinct good or service in the contract. Advance payments received in excess of revenues recognized are classified as deferred revenue until such time as the revenue recognition criteria have been met. Payment terms are net 30 from the invoice date, which is sent to the customer as we satisfy the performance obligation relative to the total expected inputs to the satisfaction of that performance obligation.

Variable Consideration. We record revenue from distributors and direct end customers in an amount that reflects the transaction price we expect to be entitled to after transferring control of those goods or services. Our current contracts do not contain any features that create variability in the amount or timing of revenue to be earned.

Warranty. We generally provide one-year warranties against defects in materials and workmanship on product sales and will either repair the products or provide replacements at no charge to customers. As they are considered assurance-type warranties, we do not account for them as separate performance obligations. Warranty reserve requirements are based on a specific assessment of the products sold with warranties where a customer asserts a claim for warranty or a product defect. 

40

Contract Balances. We record a receivable when we have an unconditional right to receive consideration after the performance obligations are satisfied. Our deferred revenues relate primarily to maintenance plans and CRO revenue.

Practical Expedients. We have elected the practical expedient not to determine whether contracts with customers contain significant financing components as well as the practical expedient to recognize shipping and handling costs at point of sale.

Stock-Based Compensation.  We account for share-based compensation expense in accordance with ASC 718, Compensation—Stock Compensation, which requires us to measure and recognize compensation expense in our financial statements based on the fair value at the date of grant for our share-based awards. We recognize compensation expense for these equity-classified awards over their requisite service period and adjust for forfeitures as they occur.

ASC 718 requires companies to estimate the fair value of stock-based payment awards on the date of grant using an option-pricing model. We use the Black-Scholes option-pricing model which requires the input of significant assumptions including an estimate of the average period of time employees and directors will retain vested stock options before exercising them, the estimated volatility of our common stock price over the expected term, the number of options that will ultimately be forfeited before completing vesting requirements and the risk-free interest rate.

When an option or warrant is granted in place of cash compensation for services, we deem the value of the service rendered to be the value of the option or warrant. In most cases, however, an option or warrant is granted in addition to other forms of compensation and its separate value is difficult to determine without utilizing an option pricing model. For that reason we also use the Black-Scholes option-pricing model to value options and warrants granted to non-employees, which requires the input of significant assumptions including an estimate of the average period that investors or consultants will retain vested stock options and warrants before exercising them, the estimated volatility of our common stock price over the expected term, the number of options and warrants that will ultimately be forfeited before completing vesting requirements and the risk-free interest rate. Changes in the assumptions can materially affect the estimate of fair value of stock-based compensation and, consequently, the related expense recognizes that. We have been on the NASDAQ Capital Market since 2015 and have had a volatile stock including reverse stock splits. The assumptions we use in calculating the fair value of stock-based payment awards represent our best estimates, which involve inherent uncertainties and the application of management's judgment. As a result, if factors change and we use different assumptions, our equity-based consulting and interest expense could be materially different in the future.

In the case of standard options to employees we determined the expected life to be the midpoint between the vesting term and the legal term. In the case of options or warrants granted to non-employees, we estimated the life to be the legal term unless there was a compelling reason to make it shorter.

Business Combination. We accounted for the zPREDICTA merger as a business combination, using the acquisition method of accounting. This method requires, among other things, that assets acquired, and liabilities assumed be recognized at fair value as of the acquisition date. The fair value for the assets acquired and the liabilities assumed are based on information knowable and determined by management as of the acquisition date. We allocate the purchase price to tangible and intangible assets acquired and liabilities assumed, based on their estimated fair values. The excess of the purchase price, if any, over the aggregate fair value of assets acquired and liabilities assumed is allocated to goodwill. 

Fixed Assets. We account for assets acquired at fair value as of the acquisition date. The fair value for assets acquired are based on their estimated fair values. Fixed assets are stated at cost less accumulated depreciation. Depreciation of fixed assets is computed using the straight-line method over the estimated useful lives of the respective assets.

41

Goodwill and Other Intangible Impairment. In accordance with ASC 350, Intangibles – Goodwill and Other, goodwill is calculated as the difference between the acquisition date fair value of the consideration transferred and the fair value of net assets acquired. Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination. Goodwill is an indefinite-lived intangible asset and is not amortized. 

Goodwill is not amortized but is tested on an annual basis for impairment at the reporting unit level as of December 31, or whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable.

To determine whether goodwill is impaired, annually or more frequently if needed, the Company performs a multi-step impairment test. The Company first has the option to assess qualitative factors to determine if it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value. The Company may also elect to skip the qualitative testing and proceed directly to the quantitative testing. When performing quantitative testing, the Company first estimates the fair values of its reporting units using discounted cash flows. To determine fair values, the Company is required to make assumptions about a wide variety of internal and external factors. Significant assumptions used in the impairment analysis include financial projections of free cash flow (including significant assumptions about operations including the rate of future revenue growth, capital requirements, and income taxes), long-term growth rates for determining terminal value and discount rates. Comparative market multiples are used to corroborate the results of the discounted cash flow test. These assumptions require significant judgement. Pursuant to ASU 2017-04, Simplifying the Test for Goodwill Impairment, the single step is to determine the estimated fair value of the reporting unit and compare it to the carrying value of the reporting unit, including goodwill. To the extent the carrying amount of goodwill exceeds the implied goodwill, the difference is the amount of the goodwill impairment. The Company also completes a reconciliation between the implied equity valuation prepared and the Company’s market capitalization. The majority of the inputs used in the discounted cash flow model are unobservable and thus are considered to be Level 3 inputs. The inputs for the market capitalization calculation are considered Level 1 inputs. See Note 10 – Intangible Assets and Goodwill.

In the Helomics acquisition, the Company recorded goodwill of $23,790,290. The goodwill was recorded to the Helomics segment which represents a single reporting unit. The cumulative losses on goodwill are $23,790,290 as of December 31, 2021. See Note 10 to our audited consolidated financial statements included in this annual report.

On November 24, 2021, the Company acquired goodwill of $6,857,790 in connection with the acquisition of zPREDICTA. The Company determined the value of the goodwill associated with the zPREDICTA reporting unit was fully recoverable at December 31, 2021.

Long-lived Assets

The Company reviews finite-lived identifiable intangible assets for impairment in accordance with ASC 360, Property, Plant and Equipment, whenever events or changes in circumstances indicate the carrying amount may not be recoverable. Events or changes in circumstances that indicate the carrying amount may not be recoverable include, but are not limited to, a significant change in the medical device marketplace and a significant adverse change in the business climate in which the Company operates.

The Company prepared an undiscounted cash flow as of December 31, 2021 to evaluate long-lived assets based on a triggering event per ASC 360. The Company concluded that the undiscounted cash flows did not support the carrying values of its the long-lived assets within the Helomics asset group at December 31, 2021. The Company determined the value of the intangibles and the software license acquired were fully impaired as of December 31, 2021 and recognized an impairment loss on its long-lived intangible assets of $2,893,548 and $1,249,727 impairment loss related to the acquired software. See Note 10 – Intangible Assets and Goodwill.

Based on a triggering event as of December 31, 2020, the Company prepared an undiscounted cash flows per ASC 360 to evaluate its other long-lived assets. The Company concluded that the undiscounted cash flows of the long-lived assets exceeded the carrying values. The Company concluded there was no impairment of its finite lived assets as of December 31, 2020.

42

Income Taxes. Deferred income taxes are provided on a liability method, whereby deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards. Deferred tax liabilities are recognized for taxable temporary differences, which are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the consolidated financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority.

Management’s Report on Internal Control Over Financial Reporting

We are responsible for establishing and maintaining adequate internal control over financial reporting. As defined in the securities laws, internal control over financial reporting is a process designed by, or under the supervision of, our principal executive and principal financial officer and effected by our Board of Directors, management, and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the acquisitions and dispositions of our assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we carried out an evaluation of the effectiveness of our internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) as of December 31, 2021 based on the criteria in “Internal Control - Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in 2013.

Board Committee Structures

The Board of Directors has determined that each current member of the Audit Committee, the Compensation Committee and the Nominating and Governance Committee meets the applicable SEC and NASDAQ rules and regulations regarding “independence” and that each member is free of any relationship that would impair their individual exercise of independent judgment with regard to us.

Below is a description of each committee of the Board of Directors as such committees are presently constituted.

Audit Committee

The Audit Committee was established by the Board in accordance with Section 3(a)(58)(A) of the Exchange Act to oversee our corporate accounting and financial reporting processes and audits of our financial statements.

All members of the Audit Committee are independent directors. Pursuant to its charter and the authority delegated to it by the Board of Directors, the Audit Committee has sole authority for oversight of our independent registered public accounting firm. In addition, the Audit Committee reviews the results and scope of the audit and other services provided by our independent registered public accounting firm, and also reviews our accounting and control procedures and policies. The Audit Committee meets as often as it determines necessary but not less frequently than once every fiscal quarter.

Our Audit Committee currently consists of Mr. Nuzum, as the chairperson, Mr. St. Clair and Dr. Chung-Welch. During 2020, the Audit Committee chairperson was Ms. Prior, who was replaced on the committee and as chairperson by Mr. Nuzum in July 2020. Each Audit Committee member is a non-employee director of the Board. The Board of Directors has determined that all current members of our Audit Committee are independent. The Audit Committee met eight times in fiscal 2021.

Audit Committee Financial Expert

The Board has determined that Mr. Nuzum meets the criteria as an “audit committee financial expert,” as defined in Item 407(d)(5)(ii) of Regulation S-K under the Securities Act of 1933, as amended. As noted above, Mr. Nuzum, Mr. St. Clair, and Dr. Chung-Welch are independent within the meaning of NASDAQ’s listing standards.

Compensation Committee

The Compensation Committee of the Board of Directors currently consists of three directors, Mr. Nuzum, as the chairperson, Dr. Chung-Welch and Mr. St. Clair. The members of the Compensation Committee were appointed by the Board of Directors and consist entirely of directors who are “outside directors” for purposes of Section 162(m) of the Internal Revenue Code of 1986, as amended, “non-employee directors” for purposes of Rule 16b-3 under the Exchange Act and “independent” as independence is currently defined in Rule 4200(a) (15) of the NASDAQ listing standards. In fiscal 2021, the Compensation Committee met eight times. The functions of the Compensation Committee include, among other things:

● approving the annual compensation packages, including base salaries, incentive compensation, deferred compensation and stock-based compensation, for our executive officers;

● administering our stock incentive plans, and subject to Board approval in the case of executive officers, approving grants of stock, stock options and other equity awards under such plans;

● approving the terms of employment agreements for our executive officers;

● developing, recommending, reviewing and administering compensation plans for members of the Board of Directors;

● reviewing and discussing the compensation discussion and analysis with management; and

● preparing any compensation committee report required to be included in the annual proxy statement.

48

All Compensation Committee approvals regarding compensation to be paid or awarded to our executive officers are rendered with the full power of the Board, though not necessarily reviewed by the full Board.

Our Chief Executive Officer may not be present during any Board or Compensation Committee voting or deliberations with respect to his compensation. Our Chief Executive Officer may, however, be present during any other voting or deliberations regarding compensation of our other executive officers but may not vote on such items of business.

Compensation Committee Interlocks and Insider Participation

As indicated above, the Compensation Committee consists of Mr. Nuzum, Dr. Chung-Welch and Mr. St. Clair. No member of the Compensation Committee has ever been an executive officer or employee of ours. None of our officers currently serves, or has served during the last completed year, on the compensation committee or the Board of Directors of any other entity that has one or more officers serving as a member of the Board of Directors or the Compensation Committee.

Nominating and Governance Committee

The Nominating and Governance Committee of the Board of Directors currently consists of Dr. Handley, as the chairperson Mr. Nuzum and Mr. Vennare. All members of the Nominating and Governance Committee are “independent directors,” as such term is defined by The NASDAQ Market Listing Rule 5605(a)(2), and free from any relationship that, in the opinion of the Board, would interfere with the exercise of his or her independent judgment as a member of the Committee.

The members of the Committee shall be elected annually by the Board. Committee members may be removed for any reason or no reason at the discretion of the Board, and the Board may fill any Committee vacancy that is created by such removal or otherwise. The Committee’s chairperson shall be designated by the full Board or, if it does not do so, the Committee members shall elect a chairperson upon the affirmative vote of a majority of the directors serving on the Committee. In fiscal 2021, the Nominating and Governance Committee met four times

The Committee may form and delegate authority to subcommittees as it may deem appropriate in its sole discretion.

In furtherance of its purposes, the Committee:

● Evaluates the composition, organization and governance of the Board, determines future requirements and make recommendations to the Board for approval;

● Determines desired Board and committee skills and attributes and criteria for selecting new directors;

● Reviews candidates for Board membership consistent with the Committee’s criteria for selecting new directors or as recommended by our stockholders. Annually, the Committee recommends a slate of nominees to the Board for consideration at our annual stockholders’ meeting;

● Develops a plan for, and consults with the Board regarding, management succession; and

● Advises the Board generally on corporate governance matters.

In addition, the Committee, if and when deemed appropriate by the Board or the Committee, develops and recommends to the Board a set of corporate governance principles applicable to the Company, and reviews and reassesses the adequacy of such guidelines annually and recommends to the Board any changes deemed appropriate. The Committee also advises the Board on (1) committee member qualifications, (2) appointments, removals and rotation of committee members, (3) committee structure and operations (including authority to delegate to subcommittees), and (4) committee reporting to the Board. Finally, the Committee performs any other activities consistent with its charter, our Certification of Incorporation, Bylaws and governing law as the Committee or the Board deems appropriate.

49

The Committee has the authority to obtain advice and seek assistance from internal or external legal, accounting or other advisors. The Committee has the sole authority to retain and terminate any search firm to be used to identify director candidates, including sole authority to approve such search firm’s fees and other retention terms.

Merger & Acquisition Committee

The Merger & Acquisition Committee of the Board of Directors currently consists of, Dr. Jenkins, as the chairperson, and Dr. Chung-Welch and Mr. Engle. The Merger & Acquisition Committee advises the Company with respect to any considered mergers, acquisitions, joint ventures and/or consolidations of any type.

Diversity

The Board of Directors currently has no formal policy regarding attaining diversity on the Board.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires our officers and directors, and persons who own more than ten percent of a registered class of our equity securities, to file reports of ownership and changes in ownership of such securities with the Securities and Exchange Commission. Officers, directors and greater than ten percent stockholders are required by Securities and Exchange Commission regulations to furnish us with copies of all Section 16(a) forms they file. Based solely on review of the copies of Forms 3 and 4 and amendments thereto furnished to us during the fiscal year ended December 31, 2021 and Forms 5 and amendments thereto furnished to us with respect to such fiscal year, or written representations that no Forms 5 were required, we believe that the following is the list of our officers, directors and greater than ten percent beneficial owners who have failed to file on a timely basis all Section 16(a) filing requirements during the fiscal year ended December 31, 2021: Carl Schwartz 1 late reporting and 1 late amendment covering 1 transaction; Charles Lee Nuzum Sr 2 late reporting covering 2 transactions; Christina Lee Jenkins MD 2 late reporting covering 2 transactions; and Raymond Vennare 1 late reporting covering 1 transaction.

Code of Ethics

We have adopted a Code of Ethics that applies to all of our employees, officers (including our principal executive officer, principal financial officer, principal accounting officer or controller, and persons performing similar functions) and directors. Our Code of Ethics satisfies the requirements of Item 406(b) of Regulation S-K and is included as an exhibit to this Form 10-K.

This section describes the material elements of the compensation awarded to, earned by or paid to our Chief Executive Officer and our Chief Financial Officer, collectively referred to as the “Named Executive Officers.” We did not have any other executive officers, as determined in accordance with SEC rules, during 2020.

Executive Compensation Components for Fiscal 2021

Base Salary. Base salary is an important element of our executive compensation program as it provides executives with a fixed, regular, non-contingent earnings stream to support annual living and other expenses. As a component of total compensation, we generally set base salaries at levels believed to attract and retain an experienced management team that will successfully grow our business and create stockholder value. We also utilize base salaries to reward individual performance and contributions to our overall business objectives but seek to do so in a manner that does not detract from the executives’ incentive to realize additional compensation through our stock options.

The Compensation Committee reviews the Chief Executive Officer’s salary at least annually. The Compensation Committee may recommend adjustments to the Chief Executive Officer’s base salary based upon the Compensation Committee’s review of his current base salary, incentive cash compensation and equity-based compensation, as well as his performance and comparative market data. The Compensation Committee also reviews other executives’ salaries throughout the year, with input from the Chief Executive Officer. The Compensation Committee may recommend adjustments to other executives’ base salary based upon the Chief Executive Officer’s recommendation and the reviewed executives’ responsibilities, experience, and performance, as well as comparative market data.

In utilizing comparative data, the Compensation Committee seeks to recommend salaries for each executive at a level that is appropriate after giving consideration to experience for the relevant position and the executive’s performance. The Compensation Committee reviews performance for both our Company (based upon achievement of strategic initiatives) and each individual executive. Based upon these factors, the Compensation Committee may recommend adjustments to base salaries to better align individual compensation with comparative market compensation, to provide merit-based increases based upon individual or company achievement, or to account for changes in roles and responsibilities.

Bonuses. Until 2018, the Chief Financial Officer received 20% contractual cash bonuses. Any other bonus for the CFO, as well as for the CEO, if offered, were determined by the Compensation Committee. The bonuses in past years were a combination of cash and employee stock options. The CFO signed an amended contract whereby the contractual bonuses were removed subsequent to August 1, 2018. All bonuses subsequent to 2018 are part of a structured program established by the Compensation Committee and approved by the Board of Directors.

Stock Options and Other Equity Grants. Consistent with our compensation philosophies related to performance-based compensation, long-term stockholder value creation and alignment of executive interests with those of stockholders, we make periodic grants of long-term compensation in the form of stock options to our executive officers, directors and others in the organization.

Stock options provide executive officers with the opportunity to purchase common stock at a price fixed on the grant date regardless of future market price. A stock option becomes valuable only if the common stock price increases above the option exercise price and the holder of the option remains employed during the period required for the option shares to vest. This provides an incentive for an option holder to remain employed by us. In addition, stock options link a significant portion of an employee’s compensation to stockholders’ interests by providing an incentive to achieve corporate goals and increase stockholder value. Under our Amended and Restated 2012 Stock Incentive Plan (the “2012 Plan”), we may also make grants of restricted stock awards, restricted stock units, performance share awards, performance unit awards and stock appreciation rights to officers and other employees. We adopted the 2012 Plan to give us flexibility in the types of awards that we could grant to our executive officers and other employees.

Amendment to Stock Option Plan. On September 3, 2020, our stockholders approved amendments to the 2012 Plan to increase the share reserve under the 2012 Plan by an aggregate 750,000 shares from the most recent reserve of 1,000,000 shares to an aggregate 1,750,000 shares. On August 17, 2021, our stockholders approved amendments to the 2012 Plan to increase the share reserve under the 2012 Plan by an aggregate 1,500,000 shares from the most recent reserve of 1,750,000 shares to an aggregate 3,250,000 shares. As of December 31, 2021, options to purchase 1,062,871 shares of common stock are subject to outstanding stock options under the 2012 Plan. In determining the amount of the increase in the 2012 Plan, the Board took into account its intention to grant further equity awards to current and future executive officers and key employees and directors.

Restricted Stock Units. Consistent with our compensation philosophies related to performance-based compensation, long-term stockholder value creation and alignment of executive interests with those of stockholders, we make periodic grants of long-term compensation in the form of restricted stock units to our executive officers.

Restricted stock units provide executive officers with stock that is not fully transferable until certain conditions are met. Upon satisfaction of the conditions, the stock is no longer restricted, and becomes transferable to the officer.

Limited Perquisites; Other Benefits. We provide our employees with a full complement of employee benefits, including health and dental insurance, short term and long-term disability insurance, life insurance, a 401(k) plan, FSA flex plan and Section 125 plan.

Long Term Incentive Plan for Executive Officers

On May 17, 2021, the Committee adopted and approved a 2021 Long Term Incentive Plan (the “LTIP”) to provide appropriate incentives to the Company’s executive officers over the critical three-year performance period consisting of fiscal years 2021, 2022 and 2023. Under the LTIP, the Company granted restricted stock units (“RSUs”) to the Company’s current CEO, J. Melville Engle, and its CFO, Bob Myers, pursuant to the Company’s Amended and Restated 2012 Stock Incentive Plan (as amended, the “Stock Incentive Plan”).

The LTIP awards consist of 300,000 RSUs for the CEO and 150,000 RSUs for the CFO granted as of May 17, 2021. Each RSU award consists of three equal tranches, corresponding to the three years in the performance period. These RSUs will vest on January 1, 2024, with the level of vesting of each tranche based on (1) the level of achievement of performance goals for the corresponding fiscal year (see below) and (2) continued employment of the executive through January 1, 2024. For each tranche, the RSUs will vest at the 100% level for performance at the target level; 50% for performance at the threshold level (with no vesting below the threshold level); and 150% for maximum performance (in other words, for maximum performance on both performance components in a fiscal year, the payout for that year would be 150% of the number of RSUs in the corresponding tranche). The level of vesting for each component is prorated between the threshold level and the target level, and between the target level and the maximum level. To the extent vested, the awards will vest on or before March 15, 2024, following the determination of the Company’s earnings per share in 2023.

 Performance-based vesting of the RSUs in the tranche for each fiscal year (100,000 RSUs per year for the CEO and 50,000 RSUs per year for the CFO) will be based equally on two components of performance:

(1)	Stock Price. A stock price component is based on the average closing share price of the Company’s common stock over the last 20 trading days of the fiscal year, as set forth in the LTIP.
(2)	Earnings (Loss) Per Share. An earnings component is based on the Company’s earnings (loss) per common share for that fiscal year, as set forth in the LTIP.

If the Committee determines that circumstances have changed and modification is required to reflect the original intent of the performance goals, the Committee may in its discretion increase (but not decrease) the number of RSUs that vest for any of the covered years.

On August 10, 2021, the stockholders approved an amendment to the Amended and Restated 2012 Stock Incentive Plan to increase the reserve of shares of common stock authorized for issuance thereunder by 1,500,000, to 3,250,000 shares. Therefore, all RSUs awarded under the LTIP will be paid in shares of common stock, rather than cash payments that might have been required had such plan amendment not been approved.

Employment Contracts

Employment Agreement with Former Chief Executive Officer.

On November 10, 2017, we entered into an employment agreement with Dr. Carl Schwartz, who has served as Chief Executive Officer from December 1, 2016 through March 19,2021. Under the agreement, the employment of Dr. Schwartz is at will.

On July 1, 2019, we entered into an amended employment agreement with Dr. Schwartz. The annualized base salary for Dr. Schwartz was $400,000 for both 2019 and 2018. Such base salary may be adjusted by us but may not be reduced except in connection with a reduction imposed on substantially all employees as part of a general reduction.

On September 23, 2020, the Compensation Committee of the Board of Directors of the Company approved the elements of a compensation program for the executive officers of the Company. The base salaries of the executive officers were increased by 15%, effective as of July 1, 2020, resulting in annualized base salaries of $460,000 for Dr. Schwartz. In addition, Dr. Schwartz was awarded a one-time, special interim grant of retention equity awards for 2020 on September 23, 2020 of 300,000 restricted stock units payable in shares of common stock and vesting in equal annual installments over three years, subject to continued employment, with accelerated vesting upon certain events, including involuntary termination without cause, voluntary termination for good reason or retirement after at least eighteen months upon at least six months’ notice.

Retirement of Former Chief Executive Officer

On March 19, 2021, Dr. Schwartz retired through his resignation as the Chief Executive Officer of the Company. In connection with the resignation, Dr. Schwartz and the Company simultaneously entered into a Transition and Separation Agreement pursuant to which, among other things, Dr. Schwartz agreed to retire from his employment and resign as a member of the Board and to provide certain transition services to the Company in exchange for the issuance to Dr. Schwartz of 100,000 shares of common stock. The Company and Dr. Schwartz also entered into an Agreement and Release pursuant to which, among other things, Dr. Schwartz and the Company released each other from any and all claims each may have against the other, and the Company agreed to provide Dr. Schwartz with certain separation benefits, including $460,000 (gross) in severance pay, equal to one year of his base salary, and the vesting of the 300,000 restricted stock units previously granted to Dr. Schwartz.

Employment Agreement with Current Chief Executive Officer

On April 5, 2021, the Company and J. Melville Engle, the Company’s current Chief Executive Officer, entered into an Employment Agreement (the “Agreement”) effective as of March 19, 2021, the first date of Mr. Engle’s employment. Pursuant to the Agreement, Mr. Engle is entitled to an annual base salary of $475,000. He will also be eligible (i) to receive an annual cash bonus equal to up to 50% of his salary, or at the discretion of the Compensation Committee (the “Committee”) of the Company’s Board of Directors, a higher percentage based on his performance and (ii) to participate in a long-term incentive plan to be adopted and maintained by the Committee. Under the LTIP, Mr. Engle will receive 100,000 restricted shares of Company common stock or restricted stock units for each of the next three calendar years of his employment, vesting over three years and subject to continued employment, with the amount that vests to be based on his performance. Mr. Engle will also be eligible to participate in the standard employee benefit plans generally available to executive employees of the Company, and, at the discretion of the Committee, to receive grants of stock options or other equity awards. Any grants of equity awards, including those above, will be made from the Company’s Amended and Restated 2012 Stock Incentive Plan or successor plans.

Under the Agreement, Mr. Engle’s employment by the Company is at-will. If his employment is terminated by the Company without “cause” or if he voluntarily resigns with “good reason” (in each case as defined in the Agreement), then Mr. Engle will be entitled to receive from the Company payment of his base salary then in effect through his last date of employment, plus accrued, unused vacation pay. In addition, Mr. Engle will be entitled to (a) severance pay in an amount equal to 12 months of his base salary then in effect, less applicable taxes and withholdings; and (b) a bonus payment on a pro-rata basis through the date of his termination.

55

The Agreement also contains customary provisions with respect to confidentiality and intellectual property, in addition to ones prohibiting Mr. Engle from soliciting the Company’s employees and from engaging in certain activities that are competitive with the Company for a period of 12 months after termination of his employment.

Employment Agreement with Chief Financial Officer.

On August 13, 2012, we entered into an employment agreement with Bob Myers, who has served as Chief Financial Officer since July 1, 2012. Under the agreement the employment of Mr. Myers is at will.

On August 20, 2018, we entered into an amendment to employment agreement with Mr. Myers. Effective August 1, 2018, Mr. Myers received an annualized base salary of $250,000. Effective August 1, 2019, Mr. Myers received an annualized base salary of $300,000.

On September 23, 2020, the Compensation Committee of the Board of Directors of the Company approved the elements of a compensation program for the executive officers of the Company. The base salaries of the executive officers were increased by 15%, effective as of July 1, 2020, resulting in annualized base salaries of $345,000 for Mr. Myers. In addition, Mr. Myers was awarded a one-time, special interim grant of retention equity awards for 2020 on September 23, 2020 of 100,000 restricted stock units payable in shares of common stock and vesting in equal annual installments over three years, subject to continued employment, with accelerated vesting upon certain events, including involuntary termination without cause, voluntary termination for good reason or retirement after at least eighteen months upon at least six months’ notice.

Base salaries for Mr. Myers may be adjusted by us but may not be reduced except in connection with a reduction imposed on substantially all employees as part of a general reduction. He will also each be eligible to receive an annual incentive bonus for each calendar year at the end of which he remains employed by us, subject to the attainment of certain objectives.

In addition, as a part of the compensation program approved in September 2020, Mr. Myers will be eligible for an annual bonus and a long-term incentive program effective January 1, 2021. Based on Company and personal performance vs. annual objectives to be established by the officers and the Committee and to be evaluated by the Committee, the officers will be granted an annual bonus opportunity ranging from 0% to 50% of base salary, or at the Board’s discretion, a higher percentage based on performance. Also, under the long-term incentive program, the officer will receive annual grants of restricted stock units on January 1 of each calendar year starting in 2021. Each grant will consist of 50,000 restricted stock units with vesting of each grant over three years based on performance and continued employment.

Mr. Myers is entitled to five (5) weeks of paid vacation per each calendar year earned ratably over each calendar year, to be taken at such times as employee and Company shall determine and provided that no vacation time shall unreasonably interfere with the duties required to be rendered by employee.

If we terminate his employment without cause or if he terminates his employment for “good reason,” he shall be entitled to receive us severance pay in an amount equal to:(1) before the first anniversary of the date of the agreement, three months of base salary, or (2) on or after the first anniversary of the date of the agreement, twelve months of base salary, in either case less applicable taxes and withholdings. In that event, he will receive a bonus payment on a pro-rata basis through the date of termination and any accrued, unused vacation pay. The severance pay, bonus payment, and other consideration are conditioned upon executive’s execution of a full and final release of liability. “Cause” is defined to mean: 1) that he engages in willful misconduct or fails to follow the reasonable and lawful instructions of the Board, if such conduct is not cured within 30 days after notice; 2) he embezzles or misappropriates assets from us or any of our subsidiaries; 3) his violation of his obligations in the agreement, if such conduct is not cured within 30 days after notice; 4) breach of any agreement between him and us or to which we and Mr. Myers are parties, or a breach of his fiduciary responsibility to us; 5) commission by Mr. Myers of fraud or other willful conduct that adversely affects our business or reputation; or, 6) we have a reasonable belief he engaged in some form of harassment or other improper conduct prohibited by Company policy or the law. “Good reason” is defined as (1) a material diminution in his position, duties, base salary, and responsibilities; or (2) our notice to Mr. Myers that his position will be relocated to an office which is greater than 100 miles from his prior office location. In all cases of Good Reason, he must have given notice to us that an alleged Good Reason event has occurred, and the circumstances must remain uncorrected by us after the expiration of 30 days after receipt by us of such notice.

56

During Mr. Myers employment and for twelve months thereafter, regardless of the reason for the termination, he may not engage in a competing business, as defined in the agreement and will not solicit any person to leave employment with us or solicit our clients or prospective clients with whom he worked, solicited, marketed, or obtained confidential information about during his employment with us, regarding services or products that are competitive with any of our services or products.

Potential Payments Upon Termination or Change of Control

Most of our stock option agreements provide for an acceleration of vesting in the event of a change in control as defined in the agreements and in the 2012 Stock Incentive Plan. However, the stock option agreements awarded to Bob Myers provide that upon the termination of such employee’s employment without cause or for good reason, such employee’s options shall become fully vested, and the vested shares may be purchased for up to five years after such termination (or such lesser period for the option if the remaining period of the option is less than five years after such termination). In addition, in the event of such employee’s retirement, death or disability, such employee’s options shall become fully vested, and the vested shares may be purchased for the entire remaining period of the option. Also, see “Employment Contracts” above for a description of certain severance compensation arrangements.

Director Compensation

Effective June 17, 2021 the Board adopted a Director Compensation Program under which the members of the Board of Directors receive quarterly awards of common stock and cash as compensation for their services as directors and annual awards of common stock and cash for services as committee members. These awards were implemented to replace the previous program of quarterly stock option grants to directors. The June 2020 annual common stock award remains in place as described below.

The compensation program pays all of the compensation in the form of stock and cash awards (with the cash component payable in additional shares at the election of the director. The cash component is equal to 28% of the total value of the award (or 38.9% of the share component of the award), intended to pay the tax on the full award.

Each director receives a quarterly award of $8,333 on the last day of the quarter, consisting of (i) shares with a value of $6,000 and (ii) $2,333 in cash (or additional shares).

For each board committee, each director receives an additional annual award of $11,112, consisting of (i) shares with a value of $8,000 and (ii) $3,112 in cash (or additional shares), payable on December 31.

Director compensation will continue to be paid to all members of the Board of Directors through December 31, 2021. Starting in 2022, director compensation will be limited to Non-Employee Directors (directors who are not employees of POAI or any subsidiary and who do not receive regular long-term cash compensation as consultants).

Effective on June 16, 2020 the Board instituted an annual common stock award for all the directors under which they will receive $7,000 in value of newly issued shares of common stock, par value $0.01 per year annually for three years, as long as they are serving as a director at the annual appointment date. Additionally, the directors will receive a $3,000 cash payment per year annually for three years, as long as they are serving as a director at the annual appointment date.

Effective on April 3, 2020 the Board instituted an annual stock options award program for the Chairman of the Board under which he/she will be awarded options to purchase $20,000 worth of shares of common stock, par value $0.01 at an exercise price determined by the close on April 2 or the last trading day prior to April 3.

Security Ownership of Certain Beneficial Owners and Management

The following table sets forth as of December 31, 2021 certain information regarding beneficial ownership of our common stock by:

● Each person known to us to beneficially own 5% or more of our common stock;

We have determined beneficial ownership in accordance with Rule 13d-3 under the Exchange Act. Beneficial ownership generally means having sole or shared voting or investment power with respect to securities. Unless otherwise indicated in the footnotes to the table, each stockholder named in the table has sole voting and investment power with respect to the shares of common stock set forth opposite the stockholder’s name. We have based our calculation of the percentage of beneficial ownership on 65,911,001 shares of our common stock outstanding on March 13, 2022. Unless otherwise noted below, the address for each person or entity listed in the table is c/o Predictive Oncology Inc., 2915 Commers Drive, Suite 900, Eagan, Minnesota 55121.

1.	Under Rule 13d-3, a beneficial owner of a security includes any person who, directly or indirectly, through any contract, arrangement, understanding, relationship, or otherwise has or shares: (1) voting power, which includes the power to vote, or to direct the voting of shares; and (2) investment power, which includes the power to dispose or direct the disposition of shares. Certain shares may be deemed to be beneficially owned by more than one person (if, for example, persons share the power to vote or the power to dispose of the shares). In addition, shares are deemed to be beneficially owned by a person if the person has the right to acquire the shares (for example, upon exercise of an option) within 60 days of the date as of which the information is provided. In computing the percentage ownership of any person, the amount of shares outstanding is deemed to include the number of shares beneficially owned by such person (and only such person) by reason of these acquisition rights. As a result, the percentage of outstanding shares of any person as shown in this table does not necessarily reflect the person’s actual ownership or voting power with respect to the number of shares of common stock actually outstanding.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the board of directors of Predictive Oncology Inc.:

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Predictive Oncology Inc. (the "Company") as of December 31, 2021 and 2020, the related consolidated statements of net loss, stockholders’ equity, and cash flows for the years ended December 31, 2021 and 2020, 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 as of December 31, 2021 and 2020, and the results of their operations and their cash flows for the years ended December 31, 2021 and 2020, 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 provides a reasonable basis for our opinion.

Critical Audit Matter

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 the 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 a separate opinion on the critical audit matter or on the account or disclosure to which it relates.

Critical Audit Matter Description

zPREDICTA, Inc. Acquisition – Fair Value of Intangible Assets

As discussed in Note 2 to the consolidated financial statements, the Company accounted for the zPREDICTA, Inc. acquisition as a business combination and allocated the purchase price amongst the tangible and intangible assets acquired and liabilities assumed. Auditing the accounting for the acquisition was complex due to the significant estimation uncertainty in determining the fair values of identifiable intangible assets, which consisted primarily of developed technology and customer relationships totaling approximately $3.7 million.

We identified the fair value of intangible assets related to developed technology and customer relationships recorded in connection with the zPREDICTA, Inc. acquisition as a critical audit matter. The fair value estimates were based on underlying assumptions about future performance of the acquired business, which involves significant estimation uncertainty. The significant assumptions used to form the basis of the fair value of the developed technology included obsolescence factors, revenue growth rates, earnings metrics, and discount rates. The significant assumptions used to form the basis of the fair value of the customer relationships included customer margins, revenue growth rates, attrition rates and discount rates. These significant assumptions are forward-looking and could be affected by future economic and market conditions.

How We Addressed the Matter in Our Audit

The primary procedures we performed to address this critical audit matter included substantively testing, with the assistance of firm personnel with expertise in the application of fair value and valuation methodologies, the appropriateness of the judgements and assumptions used in management’s process for determining the fair value of the identifiable intangibles, which included the following procedures:

● Obtained management’s purchase price allocation detailing fair values assigned to the acquired tangible and intangible assets.

● Obtained the valuation report prepared by a valuation specialist engaged by management to assist in the purchase price allocation, including determination of fair values assigned to acquired identifiable intangible assets, and examined valuation methods used and qualifications of specialist.

● Evaluating the appropriateness of the valuation methodologies used, as well as assumptions regarding the customer margins, attrition rates and discount rates related to customer relationships and the obsolescence factor and discount rates for technology, among other valuation assumptions.

● Examined the completeness and accuracy of the underlying data supporting the significant assumptions and estimates used in the valuation report, including historical and projected financial information.

● Performing inquiries of personnel at zPREDICTA, Inc. that were highly involved in the development of the forecasts to evaluate the reasonableness of revenue and margin forecasts as well as examining a sample of customer revenue contracts to support the reasonableness of the revenue forecast.

● Comparing the significant assumptions used by management to current industry and economic trends.

We have served as the Company's auditor since 2020.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations and Continuance of Operations

Predictive Oncology Inc., (the “Company” or “Predictive” or “we”) filed with the Secretary of State of Delaware a Certificate of Amendment to its Certificate of Incorporation to change the corporate name to Predictive Oncology Inc. on June 10, 2019, trading under the new ticker symbol “POAI,” effective June 13, 2019.

The Company operates in four primary business areas: first, application of artificial intelligence (“AI”) in our precision medicine business, to provide AI-driven predictive models of tumor drug response to improve clinical outcomes for patients and to assist pharmaceutical, diagnostic, and biotech industries in the development of new personalized drugs and diagnostics primarily through its wholly owned subsidiary Helomics Holding Corporation (“Helomics”); second, tumor-specific in vitro models for oncology drug discovery and research through its newly acquired wholly-owned subsidiary, zPREDICTA; third, contract services and research focused on solubility improvements, stability studies, and protein production, primarily with our Soluble Biotech subsidiary, and; fourth, production of the United States Food and Drug Administration (“FDA”)-cleared STREAMWAY System for automated, direct-to-drain medical fluid waste disposal and associated products through its incorporated division Skyline.

The Company had cash and cash equivalents of $28,202,615 as of December 31, 2021. As of December 31, 2021, there was no outstanding debt. The Company believes that its existing capital resources will be sufficient to support its operating plan for the next twelve months and beyond. However, the Company may also seek to raise additional capital to support its growth through additional debt, equity or other alternatives or a combination thereof. The Company currently expects to use cash on hand to fund capital and equipment investments, research and development, potential acquisitions and its operations, and expects such sources to be sufficient to fund its requirements over that time.

Coronavirus Outbreak

The current COVID-19 worldwide pandemic has presented substantial public health challenges. In response to the crisis, emergency measures have been imposed by governments worldwide, including mandatory social distancing and the shutdown of non-essential businesses. These measures have adversely impacted the global economy, disrupted global supply chains and created significant volatility and disruption of financial markets, and our business and operations have been and will likely continue to be materially and adversely affected. For example, our contract manufacturer for the STREAMWAY® System has been forced to change locations, thereby delaying our order fulfillment for parts. We have also reduced on-site staff at several of our facilities, resulting in delayed production, less efficiency, and our sales staff is unable to visit with hospital administrators who are our customers and potential customers. In addition, COVID-19 has impacted the Company’s capital and financial resources, including our overall liquidity position and outlook. For instance, our accounts receivable has slowed while our suppliers continue to ask for pre-delivery deposits. Ultimately, the extent of the impact of the COVID-19 pandemic on our future operational and financial performance will depend on, among other matters, the duration and intensity of the pandemic; the level of success of global vaccination efforts; governmental and private sector responses to the pandemic and the impact of such responses on us; and the impact of the pandemic on our employees, customers, suppliers, operations and sales, all of which are uncertain and cannot be predicted. These factors may remain prevalent for a significant period of time even after the pandemic subsides, including due to a continued or prolonged recession in the U.S. or other major economies. Even in areas where "stay-at-home" restrictions, masking and social distancing measures have been lifted and the number of COVID-19 cases have declined, some jurisdictions may re-impose these measures as and if variant strains emerge or cases rise. The impacts of the COVID-19 pandemic, as with any adverse public health developments, could have a material adverse effect on our business, results of operations, liquidity or financial condition and heighten or exacerbate risks described in this Annual Report on Form 10-K.

Recently Adopted Accounting Standards

The Company considers the applicability and impact of all Accounting Standards Updates (“ASUs”) issued by the Financial Accounting Standards Board (the “FASB”). Recently issued ASUs not listed below either were assessed and determined to be not applicable or are currently expected to have no impact on the condensed consolidated financial statements of the Company.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses.” This ASU added a new impairment model (known as the current expected credit loss (“CECL”) model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses. The CECL model applies to most debt instruments, trade receivables, lease receivables, financial guarantee contracts, and other loan commitments. The CECL model does not have a minimum threshold for recognition of impairment losses and entities will need to measure expected credit losses on assets that have a low risk of loss. As a smaller reporting company pursuant to Rule 12b-2 of the Securities Exchange Act of 1934, as amended, these changes become effective for the Company on January 1, 2023. Management is currently evaluating the potential impact of these changes on the consolidated financial statements of the Company.

Accounting Policies and Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and disclosure of contingent assets and liabilities at the date of the financial statements and during the reporting period. Actual results could materially differ from those estimates.

Reclassifications

Certain reclassifications have been made to the prior years’ financial statements to conform to the current year presentation. The reclassifications had no effect on previously reported results of operations, cash flows or stockholders’ equity.

Cash and cash equivalents

The Company considers all highly liquid instruments with maturities when purchased of three months or less to be cash equivalents. The Company places its cash with high quality financial institutions and believes its risk of loss is limited to amounts in excess of that which is insured by the Federal Deposit Insurance Corporation.

Receivables

Receivables are reported at the amount the Company expects to collect on balances outstanding. The Company provides for probable uncollectible amounts through charges to earnings and credits to the valuation allowance based on management’s assessment of the current status of individual accounts.

Amounts recorded in accounts receivable on the consolidated balance sheet include amounts billed and currently due from customers. The amounts due are stated at their net estimated realizable value. An allowance for doubtful accounts is maintained to provide for the estimated amount of receivables that will not be collected. The Company reviews customers’ credit history before extending unsecured credit and establishes an allowance for uncollectible accounts based upon factors surrounding the credit risk of specific customers, historical trends and other information. Invoices are generally due 30 days after presentation. Accounts receivable over 30 days is generally considered past due. The Company does not accrue interest on past due accounts receivables. Receivables are written off once all collection attempts have failed and are based on individual credit evaluation and specific circumstances of the customer. The allowance for doubtful accounts balance was $0 as of both December 31, 2021 and 2020.

F- 11

 

Fair Value Measurements

As outlined in Accounting Standards Codification (“ASC”) 820, Fair Value Measurement, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The accounting standards ASC 820 establishes a three-level fair value hierarchy that prioritizes information used in developing assumptions when pricing an asset or liability as follows:

Level 1 – Observable inputs such as quoted prices in active markets;

Level 2 – Inputs other than quoted prices in active markets, that are observable either directly or indirectly; and

Level 3 – Unobservable inputs where there is little or no market data, which requires the reporting entity to develop its own assumptions.

The Company uses observable market data, when available, in making fair value measurements. Fair value measurements are classified according to the lowest level input that is significant to the valuation.

The fair value of the Company’s investment securities, which consist of cash and cash equivalents, was determined based on Level 1 inputs. The fair value of the Company’s derivative liabilities and debt were determined based on Level 3 inputs. The Company generally uses Black Scholes method for determining the fair value of warrants classified as liabilities on a recurring basis. In addition, the Company uses the Monte Carlo method and other acceptable valuation methodologies when valuing the conversion feature and other embedded features classified as derivatives on a recurring basis. See Note 7 – Derivatives. When performing quantitative testing related to goodwill impairment analysis, the Company estimates the fair values of its reporting units using discounted cash flows. To determine fair values, the Company is required to make assumptions about a wide variety of internal and external factors. Significant assumptions used in the impairment analysis include financial projections of free cash flow (including significant assumptions about operations including the rate of future revenue growth, capital requirements, and income taxes), long-term growth rates for determining terminal value and discount rates. The majority of the inputs used in the discounted cash flow model are unobservable and thus are considered to be Level 3 inputs. See Note 10 – Goodwill and Intangibles.

The acquisition of zPREDICTA was accounted for as a business combination using the acquisition method of accounting. This method requires, among other things, that assets acquired and liabilities assumed be recognized at fair value as of the acquisition date. The fair value for the assets acquired and the liabilities assumed are based on information knowable and determined by management as of the acquisition date. The majority of the inputs used in the discounted cash flow model, the relief-from-royalty method under the income approach, the distributor method under the income approach and the multi-period excess earnings method under the income approach, each are unobservable and thus are considered to be Level 3 inputs. See Note 2 – zPREDICTA Acquisition.

Inventories

Inventories are stated at the lower of cost or net realizable value, with cost determined on a first-in, first-out basis.  

Fixed Assets

Fixed assets are stated at cost less accumulated depreciation. Depreciation of fixed assets is computed using the straight-line method over the estimated useful lives of the respective assets. Estimated useful asset life by classification is as follows: 

	Years
Computers, software and office equipment	3	-	10
Leasehold improvements (1)	2	-	5
Manufacturing tooling	3	-	7
Laboratory equipment	4	-	10
Demo equipment		3

(1) Leasehold improvements are amortized over the shorter of the useful life or the remaining lease term.

F- 12

 

Upon retirement or sale of fixed assets, the cost and related accumulated depreciation or amortization are removed from the balance sheet and the resulting gain or loss is reflected in operations. Maintenance and repairs are charged to operations expense as incurred.

Long-lived Assets

Finite-lived intangible assets consist of patents and trademarks, licensing fees, developed technology, acquired software and customer relationships, and are amortized over their estimated useful life. Accumulated amortization is included in intangibles, net in the accompanying consolidated balance sheets.

The Company reviews finite-lived identifiable intangible assets for impairment in accordance with ASC 360, Property, Plant and Equipment, whenever events or changes in circumstances indicate the carrying amount may not be recoverable. Events or changes in circumstances that indicate the carrying amount may not be recoverable include, but are not limited to, a significant change in the medical device marketplace and a significant adverse change in the business climate in which the Company operates.

The Company prepared an undiscounted cash flow as of December 31, 2021 to evaluate long-lived assets based on a triggering event per ASC 360. The Company concluded that the undiscounted cash flows did not support the carrying values of its Helomics asset group at December 31, 2021. The Company determined the value of the intangibles and the software license acquired were fully impaired as of December 31, 2021 and recognized and impairment loss of $2,893,548 for its long-lived intangible assets and $1,249,727 for the acquired software. The Company concluded there was no impairment of its other finite lived tangible assets as of December 31, 2021. See Note 10 – Intangible Assets and Goodwill.

The Company also prepared an undiscounted cash flow as of December 31, 2020 to evaluate long-lived assets based on a triggering event at that time. The Company concluded that the undiscounted cash flows of the long-lived assets exceeded the carrying values. The Company concluded there was no impairment of its finite lived assets as of December 31, 2020.

Goodwill

In accordance with ASC 350, Intangibles – Goodwill and Other, goodwill is calculated as the difference between the acquisition date fair value of the consideration transferred and the fair value of net assets acquired. Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination. Goodwill is not amortized but is tested on an annual basis for impairment at the reporting unit level as of December 31, or whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable.

To determine whether goodwill is impaired, annually or more frequently if needed, the Company performs a multi-step impairment test. The Company first has the option to assess qualitative factors to determine if it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value. The Company may also elect to skip the qualitative testing and proceed directly to the quantitative testing. When performing quantitative testing, the Company first estimates the fair values of its reporting units using discounted cash flows. To determine fair values, the Company is required to make assumptions about a wide variety of internal and external factors. Significant assumptions used in the impairment analysis include financial projections of free cash flow (including significant assumptions about operations including the rate of future revenue growth, capital requirements, and income taxes), long-term growth rates for determining terminal value and discount rates. Comparative market multiples are used to corroborate the results of the discounted cash flow test. These assumptions require significant judgement. Pursuant to ASU 2017-04, Simplifying the Test for Goodwill Impairment, the single step is to determine the estimated fair value of the reporting unit and compare it to the carrying value of the reporting unit, including goodwill. To the extent the carrying amount of goodwill exceeds the implied goodwill, the difference is the amount of the goodwill impairment. The Company also completes a reconciliation between the implied equity valuation prepared and the Company’s market capitalization. The majority of the inputs used in the discounted cash flow model are unobservable and thus are considered to be Level 3 inputs. The inputs for the market capitalization calculation are considered Level 1 inputs. See Note 3 – Intangible Assets and Goodwill.

F- 13

 

Leases – At inception of a contract a determination is made whether an arrangement meets the definition of a lease. A contract contains a lease if there is an identified asset and the Company has the right to control the asset. Operating leases are recorded as right-of-use (“ROU”) assets with corresponding current and noncurrent operating lease liabilities on our consolidated balance sheets. Financing leases are included within fixed assets with corresponding current liability within other current liabilities and noncurrent liability within other long-term liabilities on our consolidated balance sheets.

ROU assets represent our right to use an underlying asset for the duration of the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Recognition on the commencement date is based on the present value of lease payments over the lease term using an incremental borrowing rate. Leases with a term of 12 months or less at the commencement date are not recognized on the balance sheet and are expensed as incurred.

The Company has lease agreements with lease and non-lease components, which are accounted for as a single lease component for all asset classes. Leases are accounted for at a portfolio level when similar in nature with identical or nearly identical provisions and similar effective dates and lease terms.

Revenue Recognition

The Company recognizes revenue when it satisfies a performance obligation by transferring control of the promised goods or services to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Sales taxes are imposed on the Company’s sales to nonexempt customers. The Company collects the taxes from the customers and remits the entire amounts to the governmental authorities. Sales taxes are excluded from revenue and expenses.

Revenue from Product Sales

The Company has medical device revenue consisting primarily of sales of the STREAMWAY System, as well as sales of the proprietary cleaning fluid and filters for use with the STREAMWAY System. This revenue stream is reported within both the domestic and international revenue segments. The Company sells its medical device products directly to hospitals and other medical facilities using employed sales representatives and independent contractors. Purchase orders, which are governed by sales agreements in all cases, state the final terms for unit price, quantity, shipping and payment terms. The unit price is considered the observable stand-alone selling price for the arrangements. The Company sales agreement, and Terms and Conditions, is a dually executed contract providing explicit criteria supporting the sale of the STREAMWAY System. The Company considers the combination of a purchase order and acceptance of its Terms and Conditions to be a customer’s contract in all cases.

Product sales for medical devices consist of a single performance obligation that the Company satisfies at a point in time. The Company recognizes product revenue when the following events have occurred: (1) the Company has transferred physical possession of the products, (2) the Company has a present right to payment, (3) the customer has legal title to the products, and (4) the customer bears significant risks and rewards of ownership of the products. Based on the shipping terms specified in the sales agreements and purchase orders, these criteria are generally met when the products are shipped from the Company’s facilities (“FOB origin,” which is the Company’s standard shipping terms). As a result, the Company determined that the customer is able to direct the use of, and obtain substantially all of the benefits from, the products at the time the products are shipped. The Company may, at its discretion, negotiate different shipping terms with customers which may affect the timing of revenue recognition. The Company’s standard payment terms for its customers are generally 30 to 60 days after the Company transfers control of the product to its customer. The Company allows returns of defective disposable merchandise if the customer requests a return merchandise authorization from the Company.

Customers may also purchase a maintenance plan for the medical devices from the Company, which requires the Company to service the STREAMWAY System for a period of one year subsequent to the one-year anniversary date of the original STREAMWAY System invoice. The maintenance plan is considered a separate performance obligation from the product sale, is charged separately from the product sale, and is recognized over time (ratably over the one-year period) as maintenance services are provided. A time-elapsed output method is used to measure progress because the Company transfers control evenly by providing a stand-ready service. The Company has determined that this method provides a faithful depiction of the transfer of services to its customers.

All amounts billed to a customer in a sales transaction for medical devices related to shipping and handling, if any, represent revenues earned for the goods provided, and these amounts have been included in revenue. Costs related to such shipping and handling billing are classified as cost of goods sold. This revenue stream is reported under the Skyline reportable segment.

Revenue from Clinical Testing

Clinic diagnostic testing is comprised of our Tumor Drug Response Testing (ChemoFx) and Genomic Profiling (BioSpeciFx) tests. The Tumor Drug Response Testing test determines how a patient’s tumor specimen reacts to a panel of various chemotherapy drugs, while the Genomic Profiling test evaluates the expression and/or status of a particular gene related to a patient’s tumor specimen. Revenues are recognized when control of the promised goods or services is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The estimated uncollectible amounts are generally considered implicit price concessions that are a reduction in revenue. Helomics’ payments terms vary by the agreements reached with insurance carriers and Medicare. The Company’s performance obligations are satisfied at one point in time when test reports are delivered.

For service revenues, the Company estimates the transaction price which is the amount of consideration it expects to be entitled to receive in exchange for providing services based on its historical collection experience using a portfolio approach as a practical expedient to account for patient contracts as collective groups rather than individually. The Company monitors its estimates of transaction price to depict conditions that exist at each reporting date. If the Company subsequently determines that it will collect more consideration than it originally estimated for a contract with a patient, it will account for the change as an increase to the estimate of the transaction price, provided that such downward adjustment does not result in a significant reversal of cumulative revenue recognized.

The Company recognizes revenue from these patients when contracts as defined in ASC 606, Revenue from Contracts with Customers are established at the amount of consideration to which it expects to be entitled or when the Company receives substantially all of the consideration subsequent to the performance obligations being satisfied. The Company’s standard payment term for hospital and patient direct bill is 30 days after invoice date. This revenue stream is reported under the Helomics segment.

CRO Revenue

Contract revenues are generally derived from studies conducted with biopharmaceutical and pharmaceutical companies. The specific methodology for revenue recognition is determined on a case-by-case basis according to the facts and circumstances applicable to a given contract. The Company typically uses an input method that recognizes revenue based on the Company’s efforts to satisfy the performance obligation relative to the total expected inputs to the satisfaction of that performance obligation. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation on the basis of the standalone-selling price of each distinct good or service in the contract. Advance payments received in excess of revenues recognized are classified as deferred revenue until such time as the revenue recognition criteria have been met. Payment terms are net 30 from the invoice date, which is sent to the customer as the Company satisfies the performance obligation relative to the total expected inputs to the satisfaction of that performance obligation. This revenue stream is reported under the Helomics and zPREDICTA segments.

F- 15

 

Variable Consideration

The Company records revenue from distributors and direct end customers in an amount that reflects the transaction price it expects to be entitled to after transferring control of those goods or services. The Company’s current contracts do not contain any features that create variability in the amount or timing of revenue to be earned.

Warranty

The Company generally provides one-year warranties against defects in materials and workmanship on product sales and will either repair the products or provide replacements at no charge to customers. As they are considered assurance-type warranties, the Company does not account for them as separate performance obligations. Warranty reserve requirements are based on a specific assessment of the products sold with warranties where a customer asserts a claim for warranty or a product defect. 

Contract Balances

The Company records a receivable when it has an unconditional right to receive consideration after the performance obligations are satisfied. As of December 31, 2021 and 2020, accounts receivable totaled $354,196 and $256,878, respectively.

The Company’s deferred revenues related primarily to our zPREDICTA contract research revenue and maintenance plans of our Skyline Medical operating segment. As of December 31, 2021 and 2020, deferred revenue was $186,951 and $53,028, respectively.

Practical Expedients

The Company has elected the practical expedient not to determine whether contracts with customers contain significant financing components as well as the practical expedient to recognize shipping and handling costs at point of sale.

Valuation and accounting for stock options and warrants

The Company determines the grant date fair value of options and warrants using a Black-Scholes option valuation model based upon assumptions regarding risk-free interest rate, expected dividend rate, volatility and estimated term.

The fair value of each option and warrant grant is estimated on the grant date using the Black-Scholes option valuation model with the following assumptions:

	For the Year Ended December 31,
	2021			2020
	Stock Options
Expected dividend yield		0.0%			0.0%
Expected stock price volatility	84.8%	-	89.6%	82.6%	-	87%
Risk-free interest rate	0.93%	-	1.66%	0.13%	-	1.78%
Expected life (years)		10			10
	Warrants
Expected dividend yield		0.0%			0.0%
Expected stock price volatility		84.8%		82.6%	-	87%
Risk-free interest rate	0.42%	-	0.69%	0.135%	-	0.79%
Expected life (years)	5/		5.5	5/		5.5

F- 16

 

Research and Development

Research and development costs are charged to operations as incurred. Research and development costs were $315,850 and $372,710 for the years ended 2021 and 2020, respectively.

Other Expense

Other expense consisted primarily of interest expense, payment penalties, amortization of original issue discounts, and loss on debt extinguishment associated to the Company’s notes payable.

Offering Costs

Costs incurred which are direct and incremental to an offering of the Company’s securities are deferred and charged against the proceeds of the offering, unless such costs are deemed to be insignificant in which case they are expensed as incurred.

Income Taxes

The Company accounts for income taxes in accordance with ASC 740, Income Taxes (“ASC 740”). Under ASC 740, deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities and net operating loss and credit carryforwards using enacted tax rates in effect for the year in which the differences are expected to impact taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized.

The Company reviews income tax positions expected to be taken in income tax returns to determine if there are any income tax uncertainties. The Company recognizes tax benefits from uncertain tax positions only if it is more likely than not that the tax positions will be sustained on examination by taxing authorities, based on technical merits of the positions. The Company has identified no income tax uncertainties.

Under Internal Revenue Code Section 382, certain stock transactions which significantly change ownership could limit the amount of net operating carryforwards that may be utilized on an annual basis to offset taxable income in future periods. The Company has not yet performed an analysis of the annual net operating loss carryforwards and limitations that are available to be used against taxable income. Consequently, the limitation, if any, could result in the expiration of the Company’s loss carryforwards before they can be utilized. The Company has not analyzed net operating loss carryforwards under Section 382 to date. As a result of the Helomics acquisition, there may be significant limitation to the net operating loss. In addition, the current NOL carryforwards might be further limited by future issuances of our common stock.

Tax years subsequent to 2001 remain open to examination by federal and state tax authorities due to unexpired net operating loss carryforwards.

Credit Risk

Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash. The Company places its cash with high credit quality financial institutions and, by policy, generally limits the amount of credit exposure to any one financial institution. As of December 31, 2021. the Company did not have credit risk for cash amounts held in a single institution that are in excess of amounts issued by the Federal Deposit Insurance Corporation.

Risks and Uncertainties

The Company is subject to risks common to companies in the medical device and biopharmaceutical industries, including, but not limited to, development by the Company or its competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, and compliance with regulations of the Food and Drug Administration, Clinical Laboratory Improvement Amendments, and other governmental agencies.

The Company has evaluated all of its activities and concluded that no other subsequent events have occurred that would require recognition in the consolidated financial statements or disclosure in the notes to the consolidated financial statements, except as described above and in Note 16 – Subsequent Events.

NOTE 2 – zPREDICTA ACQUISITION

On November 24, 2021, the Company entered into an Agreement and Plan of Merger (the “Agreement”) among the Company, a wholly-owned subsidiary of the Company (the “Merger Sub”), zPREDICTA, and a representative for certain parties who held interests in zPREDICTA. Also on November 24, 2021, the Company acquired zPREDICTA through the merger of Merger Sub with and into zPREDICTA, with zPREDICTA surviving as a wholly-owned subsidiary of the Company.

As consideration for the acquisition, the stockholders and certain holders of interests in zPREDICTA as of immediately prior to the transaction collectively received consideration of approximately $10.0 million in cash. The Agreement contains customary and negotiated representations, warranties, and indemnity provisions.

The acquisition costs of $895,297 related to the acquisition are presented in legal, accounting and consulting expenses within general and administrative expenses in the accompanying consolidated statements of net loss.

The following table summarizes the acquisition date fair values of assets acquired and liabilities assumed, and the consideration transferred:

Cash consideration	$	10,015,941
Assets acquired:
Cash		425,727
Accounts receivable		76,549
Prepaid expenses		25,733
Intangible assets		3,780,000
Liabilities assumed:
Accrued expenses		(408,825	)
Deferred tax liability		(661,658	)
Deferred revenue		(79,375	)
Goodwill	$	6,857,790

The purchase price allocation has been derived from estimates. The Company’s judgements used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed can materially affect the consolidated operations of the consolidated Company. The total purchase price has been allocation to identifiable assets acquired and liabilities assumed based upon valuation studies and procedures performed to date. The fair value and useful life for the intangible assets are (a) tradename $80,000 b) developed technology $3,500,000 and c) customer relationships $200,000 with useful lives of 4 years, 10 years and 10 years, respectively all using a straight-line method.

The Company acquired zPREDICTA through a non-taxable reverse triangular merger combination. As part of purchase accounting there was $3,780,000 in fair value assigned to purchased intangibles which the Company established a related deferred tax liability as a result of the stock merger combination that offset the acquired deferred assets including NOL’s and other temporary timing differences.

Identifiable Intangible Assets

The Company acquired intangible assets related to trademarks for the acquired zPREDICTA trade name with an estimated fair market value of $80,000. The fair values of the asset were determined by the relief-from-royalty method under the income approach. The Company determined the asset is a finite lived asset. The useful life of the tradename has a remaining useful life of 4 years as of December 31, 2021.

The Company acquired intangible assets with a useful life of 10 years and an estimated value of $200,000 related to customer relationships stemming from stable and predictable cash flow streams associated with customers. zPREDICTA’s customer base includes contract research partnerships with pharmaceutical, diagnostic, biotechnology, and research companies. The customer relationships were valued using the distributor method under the income approach.

F- 18

 

The Company acquired intangible assets with a useful life of 10 years and an estimated value of $3,500,000 related to developed technology stemming from the 3D tumor model technology. Since the model technology was identified as the primary asset, this technology was valued using the multi-period excess earnings method under the income approach.

Goodwill

Goodwill of $6,857,790 was recognized in the zPREDICTA acquisition and represents the excess of the consideration transferred over the fair values of assets acquired and liabilities assumed and represents the future economic benefits and synergies arising from the transaction. None of the goodwill will be deductible for income tax purposes. See Note 10 – Goodwill and Intangibles.

Financial Results

The financial results of zPREDICTA since the acquisition date have been included in the Company’s accompanying consolidated statements of net loss.

Pro Forma

The following pro forma information presents the combined results of operations of the Company and zPREDICTA as if the acquisition of zPREDICTA had been completed on January 1, 2020, with adjustments to give effect to pro forma events that are directly attributable to the acquisition.

	2021			2020
	Unaudited			Unaudited
Revenue	$	2,429,786		$	1,815,560
Net loss attributable to common shareholders	$	(18,878,432	)	$	(26,946,564	)

The primary adjustments include the inclusion of the revalued amortization for zPREDICTA intangible assets. The unaudited pro forma results do not reflect any operating efficiencies or potential cost savings which may result from the consolidation of operations. Accordingly, these unaudited pro forma results are presented for informational purposes only and are not necessarily indicative of what the actual results of operations of the combined company would have been if the acquisition had occurred at the beginning of those respective time periods, nor are they indicative of future results of operations.

There are certain portions of purchase accounting, specifically Section 382 for Tax Loss Carryforwards, which take place after a company has undergone a shift in ownership, that the Company has not completed yet and may have a significant impact on the financial statements.

NOTE 3 – INVENTORIES

Inventories are stated at the lower of cost or net realizable value, with cost determined on a first-in, first-out basis. Inventory balances consist of the following:

	December 31, 2021		December 31, 2020
Finished goods	$	193,287	$	95,898
Raw materials		183,410		151,366

NOTE 4 – STOCKHOLDERS’ EQUITY, STOCK OPTIONS AND WARRANTS

Authorized Shares

At the special meeting on August 17, 2021, the stockholders approved a proposal to increase the number of authorized shares of common stock to 200,000,000 shares of common stock, $0.01 par value. The amendment to the certificate of incorporation to affect this increase was filed on August 17, 2021.

2021 Offerings

In January and February 2021, the Company completed a series of five offerings, all of which were priced at-the-market under applicable NASDAQ rules. The first four offerings were registered direct offerings of common stock under its shelf registration statement, and in each such case, in a concurrent private placement, the Company also issued such investors one warrant to purchase common stock for each two shares purchased in the transaction. Following those four offerings, the Company completed a private placement of common stock, with each investor receiving one warrant to purchase common stock for each two shares purchased in the transaction. In June 2021, the Company completed a registered direct offering of common stock and warrants. The warrants became exercisable on the effective date of an increase in the number of shares of the Company’s authorized common stock, which occurred on August 17, 2021, and expire three years after the initial exercise date. In each case, each such investor warrant is exercisable immediately upon issuance and will expire five and one-half years from the issue date. In each case, the Company paid to the placement agent an aggregate fee equal to 7.5% of the aggregate gross proceeds received by the Company in the offering and a management fee equal to 1% of the aggregate gross proceeds received by the Company in the offering and reimbursed the placement agent for certain non-accountable and out-of-pocket expenses. In addition, the Company granted to the placement agent, or its assigns warrants to purchase 7.5% of the shares sold to investors in the offering at an exercise price equal to 125% of the price of the shares in the transaction, with a term of five years for the registered direct offerings (three years for the June 2021 offering) or five and one-half years for the private placement.

These 2021 offerings were as follows:

Offering Closing Date	Shares		Sale Price per Share*		Investor Warrants		Exercise Price per Share – investor Warrants		Placement Agent Warrants		Exercise Price per Share – Placement Agent Warrants		Gross Proceeds of Offering		Net Proceeds of Offering

2021 Warrant Exercises

During the year ended December 31, 2021, the holders of outstanding investor warrants have exercised such warrants for the total purchase of 5,269,059 shares at a weighted average exercise price of $0.86 per share, for total proceeds of $4,513,871.

Equity Line

On October 24, 2019, the Company entered into an equity purchase agreement with an investor, providing for an equity financing facility. Upon the terms and subject to the conditions in the purchase agreement, the investor is committed to purchase shares having an aggregate value of up to $15,000,000 of the Company’s common stock for a period of up to three years. The Company issued to the investor 104,651 commitment shares at a fair market value of $450,000 for entering into the agreement. From time to time during the three-year commitment period, provided that the closing conditions are satisfied, the Company may provide the investor with put notices to purchase a specified number of shares subject to certain limitations and conditions and at specified prices, which generally represent discounts to the market price of the common stock. During the year ended December 31, 2020, the Company issued 4,231,073 shares of common stock valued at $4,891,348 pursuant to the equity line. As of December 31, 2021, there was $9,113,829 of remaining available balance under the equity line, subject to shareholder approval required for additional purchases, as well as requirements for market conditions including trading volume and stock price, and subject to other limitations. During the year ended December 31, 2021, the Company issued 647,504, shares of its common stock valued at $675,590 pursuant to the equity line.

Series D Preferred Stock

In April 2019, the Company issued 3,500,000 shares of Series D preferred stock to Helomics as part of its acquisition of Helomics. Each share of Series D preferred stock is subject to automatic conversion, whereby each such share converts automatically on a 10:1 basis into a share of the Company’s common stock upon the earlier of (1) the consummation of any fundamental transaction (e.g., a consolidation or merger, the sale or lease of all or substantially all of the assets of Predictive or the purchase, tender or exchange offer of more than 50% of the outstanding shares of voting stock of Predictive,) or (2) the one-year anniversary of the issuance date. On April 4, 2020, 3,500,000 shares of Series D convertible preferred stock were converted into 350,004 shares of common stock.

Series E Convertible Preferred Stock

In June through September 2019, the Company entered into a private placement securities purchase agreement with investors for shares of Series E convertible preferred stock. The Company issued 258 preferred shares. Each preferred shareholder had the right to convert each Series E convertible preferred share into 0.056857% of the issued and outstanding shares of common stock immediately prior to conversion for each share of Series E convertible stock, beginning six months after the initial close date of June 13, 2019. On the date that is 12 months after the initial closing date, the Company has the option to convert the preferred shares into common stock upon the same terms and limitations as the above optional conversion. The preferred shares included a contingent beneficial conversion amount of $289,935, representing the intrinsic value of the shares at the time of issuance. The Company determined the Series E convertible preferred stock should be classified as permanent equity and the beneficial conversion feature amount was accreted through the earliest redemption date of December 13, 2019.

F- 21

 

During the first quarter of 2020, 50 shares of Series E convertible preferred stock were converted into 141,191 shares of common stock. In May 2020, we notified the holders of our Series E Convertible Preferred Stock of our election to convert the outstanding shares of Series E Stock into common stock effective on June 13, 2020 pursuant to the terms of the Series E Stock. Prior to the conversion, there were 207.7 shares of Series E Stock outstanding. Each share of Series E Stock converted into 0.056857% of the issued and outstanding shares of common stock immediately prior to conversion; therefore, the 207.7 outstanding shares of Series E Stock on June 13, 2020 converted into 1,257,416 shares of common stock equal to 11.8% of the outstanding shares of common stock as of June 12, 2020.

March 2020 Private Placement

On March 18, 2020, we sold and issued to private investors (i) 260,000 shares of common stock, at a sale price of $2.121 per share; (ii) prefunded warrants to acquire 1,390,166 shares of common stock, sold at $2.12 per share and exercisable at an exercise price of $0.001 per share; (iii) Series A warrants to acquire 1,650,166 shares of Common Stock at $1.88 per share, exercisable immediately and terminating five and one-half years after the date of issuance; and (iv) Series B warrants to acquire 1,650,166 shares of Common Stock at $1.88 per share, exercisable immediately and terminating two years after the date of issuance. See below for amendment dated September 23, 2020.

In addition, and in lieu of common shares, the investors also purchased prefunded warrants to purchase 1,390,166 shares of common stock at a purchase price of $2.12 per prefunded warrant, which represents the per share offering price, minus the $0.0001 per share exercise price of each such prefunded warrant. As a result of the prefunded warrants exercise price being of a nominal amount, these warrants were included as outstanding shares within our earnings per share calculation during the period from purchase through to exercise during the second quarter 2020.

The sale of the offering shares, prefunded warrants and A and B warrants resulted in gross proceeds of $3,498,612 and net proceeds of $3,127,818 after deducting the placement agent fees and estimated offering expenses payable by the Company. The Company agreed to use the net proceeds from the offering for general corporate purposes. The offering closed on March 18, 2020, subject to the satisfaction of customary closing conditions.

Effective September 23, 2020, the Company amended the terms of A and B warrants. Earlier in September, the Company notified the holders of the warrants that the Company would accept an exercise price therefor of $0.8457, amended from the original exercise price of $1.88 per share. The amendment also modified the settlement provisions of the warrants under certain circumstances; this change resulted in a classification change from derivative liability to equity classification. See Note 7 –– Derivatives for discussion of A, B and agent warrants accounted for as derivative liabilities prior to September 23, 2020.

Dr. Schwartz Note Exchange

Effective as of April 21, 2020, the Company and Carl Schwartz, entered into an exchange agreement relating to a promissory note of the Company dated January 31, 2020 issued by the Company in the principal amount of $2,115,000. Pursuant to the exchange agreement, Dr. Schwartz was issued 1,583,481 shares of newly issued common stock at an exchange rate of $1.43 per share. See Note 5 – Notes Payable.

May 2020 Registered Direct Offering and Concurrent Private Placement of Warrants

During May 2020, the Company entered into a securities purchase agreement with certain accredited investors for a registered direct offering of 1,396,826 shares of common stock, par value $0.01 per share. In a concurrent private placement, the Company also issued such investors warrants to purchase up to an aggregate of 1,396,826 shares of common stock. The shares and the warrants were sold at a combined offering price of $1.575 per share and associated warrant. Each warrant is exercisable immediately upon issuance at an exercise price of $1.45 per share and will expire five and one-half years from the issue date. The sale of the offering shares and associated warrants resulted in gross proceeds of $2,200,001 and net proceeds of $1,930,100 after deducting the placement agent fees and offering expenses payable by the Company. The Company used the net proceeds from the offering to repay certain indebtedness and agreed to use the remaining net proceeds from the offering for general corporate purposes. The offering closed on May 8, 2020.

Acquisition from Soluble Therapeutics and BioDtech

On May 27, 2020, the Company entered into an Asset Purchase Agreement with InventaBioTech, Inc. (“InventaBioTech”) and two of its subsidiaries, Soluble Therapeutics, Inc. (“Soluble”), and BioDtech, Inc. (“BioDtech”), and simultaneously completed the acquisition of substantially all of Soluble’s and BioDtech’s assets. In exchange, the Company issued 125,000 shares of common stock and waived all existing claims that the Company has or may have against InventaBioTech (f/k/a CytoBioscience, Inc.), including the nonpayment of $1,290,000 owing by InventaBioTech to the Company. All of the shares issued in the acquisition were deposited into escrow, with 25,000 released upon the six-month anniversary of the closing, 25,000 released upon the nine-month anniversary of the closing, and the remaining shares released on May 26, 2021. Notwithstanding the foregoing, all or some of the escrow shares may be released and returned to the Company for reimbursement in the event that the Company suffers a loss against which InventaBioTech, Soluble, and BioDtech have indemnified the Company pursuant to the Agreement. The Company is also entitled to reclaim 10,000 of the shares if, within six months of the closing, the Company is unable to successfully obtain ownership of all of Soluble’s interest under its license agreement with the UAB Research Foundation. As a result of the acquisition, which was treated as an asset acquisition, the Company recognized fixed assets of $1,492,500.

June 2020 Warrant exercise and issuance

During June 2020, the Company entered into an agreement with certain accredited institutional investors to immediately exercise for cash an aggregate of 1,396,826 of the warrants issued in connection with the May 2020 Registered Direct Offering, exercisable immediately at the exercise price of $1.45 per share of common stock plus an additional $0.125 for each new warrant to purchase up to a number of shares of common stock equal to 100% of the number of shares issued pursuant to the exercise of the existing warrants. The new warrants are exercisable immediately and have a term of five and one-half years and an exercise price per share equal to $1.80. The Company received $2,130,701 in gross proceeds and net proceeds of $1,865,800 after deducting the placement agent fees and offering expenses payable by the Company.

Effective on September 23, 2020, the Company amended the terms of warrants to purchase up to 1,396,826 shares of the Company’s common stock, par value $0.01 per share. The amendment modified the settlement provisions of the warrants under certain circumstances; this change resulted in a classification change from derivative liability to equity classification.

Acquisition of Quantitative Medicine

On July 1, 2020, the Company entered into an Asset Purchase Agreement with Quantitative Medicine LLC (“QM”), a Delaware limited liability company and its owners and simultaneously completed the acquisition of substantially all of QM’s assets owned by Seller. QM is a biomedical analytics and computational biology company that developed a novel, computational drug discovery platform called CoRE. CoRE is designed to dramatically reduce the time, cost, and financial risk of discovering new therapeutic drugs by predicting the main effects of drugs on target molecules that mediate disease. In exchange for QM’s assets, including CoRE, the Company provided consideration in the form of 954,719 shares of common stock, which, when issued, had a fair value of $1,470,267. One half of the shares issued, or 477,359 shares were deposited and held in escrow upon issuance, while 207,144 of the remaining shares were issued to Carnegie Mellon University (“CMU”) in satisfaction of all pre-closing amounts owed to CMU under a technology licensing agreement that was assumed by the Company on the closing date. Half of the shares held in escrow were released on the six-month anniversary of the closing date, and the other half was released on the one-year anniversary of the closing date.

Warrants Issued in Connection with Helomics Acquisition         

Effective on September 14, 2020, the Company amended the terms of warrants to purchase up to 1,424,506 shares of the Company’s common stock, par value $0.01 per share, which were issued to certain holders in connection with the Company’s merger transaction with Helomics on April 4, 2019. In September 2020, the Company notified the holders of the warrants that the Company will accept an exercise price of $0.845, equal to the last reported per share price of Common Stock on the NASDAQ Capital Market on September 11, 2020, amended from the original exercise price of $10.00 per share (as adjusted for a one-for-ten (1:10) reverse stock split that was effective on October 29, 2019). The value of the amendment was determined based on the increase in the fair value on the date of modification using the Black Scholes method and equaled $554,287. The amendment was accounted for as a deemed dividend and increased the loss attributable to the common shareholders when calculating earnings per share. The Warrants were issued on April 4, 2019 to holders of warrants in Helomics; the Warrants expire on April 4, 2024. See Note 8 – Loss per Share.

Equity Incentive Plan

The Company has an equity incentive plan, which allows issuance of incentive and non-qualified stock options, stock appreciation rights, stock awards, restricted stock, restricted stock units and performance awards to employees, directors and consultants of the Company, where permitted under the plan. The exercise price for each stock option is determined by the market price on the date of issuance. Vesting requirements are determined by the Board of Directors when granted and currently range from immediate to three years. Options outstanding under this plan have a contractual life of ten years.

At the special meeting on August 17, 2021, the stockholders approved a proposal to increase the reserve shares of common stock authorized for issuance under the Amended and Restated 2012 Stock Incentive Plan by 1,500,000 to 3,250,000 reserve shares.

Options and Warrants

ASC 718, Compensation – Stock Compensation, (“ASC 718”) requires that a company that issues equity as compensation needs to record compensation expense on its statements of net loss that corresponds to the estimated cost of those equity grants. ASC 718 requires companies to estimate the fair value of stock-based payment awards on the date of grant using an option-pricing model or other acceptable means.

The Company determines the grant date fair value of options and warrants using a Black-Scholes option valuation model based upon assumptions regarding risk-free interest rate, expected dividend rate, volatility and estimated term. See Note 1 – Summary of Significant Accounting Policies – Accounting Policies and Estimates.

NOTE 5– NOTES RECEIVABLE

The Company had a secured promissory note receivable from CytoBioscience for $1,112,524 (“2017 Promissory Note”), plus interest paid monthly at the per annum rate of (8%) on the principal amount. Unpaid principal and unpaid accrued interest on the note were due and payable on February 28, 2020. In 2019, CytoBioscience and its parent company, InventaBioTech, paid interest in the first quarter due through April 2019. The Company had not received any payments from CytoBioscience since the first quarter of 2019. The Company had evaluated the feasibility of repayment and concluded that it was probable that the Company would be unable to collect all amounts due according to the contractual terms of the receivable. During 2019, the Company recorded a valuation allowance of $1,037,524 related to the notes receivable balance. During 2019, the Company also recorded a loss on this note for the uncollected balance.

On May 27, 2020, the Company entered into an Asset Purchase Agreement with InventaBioTech, Inc. (“InventaBioTech”) and two of its subsidiaries, Soluble Therapeutics, Inc. (“Soluble”), and BioDtech, Inc. (“BioDtech”), and simultaneously completed the acquisition of substantially all of Soluble’s and BioDtech’s assets. In exchange, the Company issued 125,000 shares of common stock and waived all existing claims that the Company has or may have against InventaBioTech (f/k/a CytoBioscience, Inc.). Prior to the completion of the transaction, InventaBioTech owed the Company approximately $1,290,000 under the 2017 Promissory Note, which was secured by certain intellectual property and equipment useful in CRO. In connection with the asset purchase agreement, the Company recognized a gain on the note previously determined to be uncollectable of $1,290,000 and recognized fixed assets of $1,492,500.

In September 2018, the Company issued convertible secured promissory notes to two private investors in the original principal amount of an aggregate $2,297,727 (together, the “2018 Investor Note”) in exchange for cash proceeds of $2,000,000.

The 2018 Investor Note accrued interest at a rate of 8% per annum. In February 2019, the Company entered into a forbearance agreement with the 2018 Investor Note investors pursuant to which, among other things, the investors agreed to forbear on their rights to accelerate the 2018 Investor Note based on an event of default and a claimed event of default. In connection with such forbearance, an additional $344,659 in principal and an additional 16,667 common shares were issued to the investors. In September 2019, the 2018 Investor Note of one investor was paid in full. On March 19, 2020, the Company and the L2 Capital, LLC (“L2”) agreed to extend the note maturity to June 28, 2020. The Company and L2 further agreed to extend the due date to July 15, 2020 and then in July 2020 agreed to extend to September 30, 2020. Effective September 30, 2020, L2 and the Company agreed to extend to March 31, 2021.

During the year ended December 31, 2020, L2 converted $267,328 of the principal balance, and received 170,000 shares of the Company’s common stock.

During September 2019, the Company issued a secured promissory note with a principal amount of $847,500 (the “2019 Investor Note”) to Oasis Capital, LLC (“Oasis”), an affiliate of L2, in exchange for cash proceeds of $700,000. As additional consideration for the loan, the Company issued an aggregate 8,857 shares of its common stock to Oasis plus warrants to acquire up to 68,237 shares of the Company’s common stock at an exercise price of $6.21 per share. The warrants are exercisable beginning on the sixth month anniversary of the effective date through the fifth-year anniversary thereof.

On March 19, 2020, the Company entered into an agreement to extend the due date the 2019 Investor Note from March 2020 to June 27, 2020. The Company increased the principal amount due on the 2019 Investor Note by $300,000 and issued 30,000 shares of its common stock as consideration for the extension. The change in value resulting from the extension exceeded 10% and as a result the extension was accounted for as an extinguishment under ASC 470, Debt. During the first quarter of 2020, the Company incurred a $300,000 loss on debt extinguishment related to the extension of the note. The Company and Oasis further agreed to extend the due date of the note to July 15, 2020 and then agreed to extend to September 30, 2020. The change in value resulting from the extension to September 30, 2020 exceeded 10% and as a result the extension was accounted for as an extinguishment under ASC 470, Debt. During the third quarter of 2020, the Company incurred a $345,000 loss on debt extinguishment related to the extension of the 2019 Investor Note to September 30, 2020.

The change in value resulting from the extension to March 31, 2021 exceeded 10% and as a result the extension was accounted for as an extinguishment under ASC 470, Debt. During the third quarter of 2020, the Company incurred a $690,000 loss on debt extinguishment related to the extension of the note to March 31, 2021. Further, the parties agreed that the note shall be convertible into shares of the Company’s common stock, at a conversion price equal to the lesser of (i) $1.00 and (ii) 70% of the lowest VWAP (as defined in the note) of the Company’s common stock during the twenty (20) Trading Day (as defined) period ending on either (i) the last complete Trading Day prior to the conversion date or (ii) the conversion date, as determined by the holder in its sole discretion upon such conversion (subject to adjustment). During the fourth quarter of 2020, Oasis converted $525,000 in outstanding principal of the 2019 Investor Note in exchange for 1,136,448 shares of the Company’s common stock. No payment penalties were paid in relation to payments on this promissory note during the year ended December 31, 2020 and $320,542 in payment penalties were accrued but not paid as of December 31, 2020. As of December 31, 2020, the remaining balance on the promissory note was $1,490,833 with $244,830 unamortized discount.

On February 5, 2020, the Company issued a secured promissory note with a principal amount of $1,450,000 (the “2020 Investor Note”) to Oasis. Net proceeds of $400,000 were received for each of the first, second, and third tranches on February 5, 2020, March 5, 2020, and April 5, 2020, respectively. The Company granted to Oasis a security interest in its assets to secure repayment of the note. The 2020 Investor Note accrued interest at a rate of 8% per annum. Subject to certain limitations, the outstanding principal amount of the note and interest thereon were convertible at the election of the investor into shares of the Company’s common stock at a conversion price equal to $2.589. The conversion price was amended effective September 30, 2020 to a variable price equal to 70% of the lowest VWAP (as defined in the note) of Company’s common stock during the twenty (20) Trading Day (as defined in the note) period ending on either (i) the last complete Trading Day prior to the conversion date or (ii) the conversion date, as determined by the holder in its sole discretion upon such conversion (subject to adjustment). The note contains a conversion feature and a put which were determined to be derivatives and are discussed further below. Effective July 15, 2020, the Company and Oasis agreed to amend the maturity date of the note to September 30, 2020. The change in value resulting from the amendment to maturity to September 30, 2020 exceeded 10% and as a result the amendment was accounted for as an extinguishment under ASC 470, Debt. During the third quarter of 2020, the Company incurred a $172,500 loss on debt extinguishment related to the amendment of the note to September 30, 2020.

Dr. Schwartz Notes

In November 2018, Dr. Schwartz made a loan to the Company with a principal balance of $370,000. As of December 31, 2018, one promissory note was held with a principal balance of $370,000 and an unamortized discount of $63,028. From November 30, 2018 through July 15, 2019, Dr. Schwartz made numerous loans to the Company in the total amount of $1,920,000 under two promissory notes. As consideration for these amounts, Dr. Schwartz received promissory notes and warrants to purchase 22,129 shares of the Company’s common stock at $8.36 per share. Further, beginning on February 1, 2019 and the first day of each calendar month thereafter while the note remained outstanding, a number of additional warrants were issued. Beginning in October 2019, the Company and Dr Schwartz began to renegotiate the note. Due to the negotiations, the Company did not issue any additional warrants because they would be cancelled under the new deal.

During January 2020, the Company entered into an exchange agreement with Dr. Schwartz. Under the exchange agreement, the two outstanding notes were cancelled and in exchange a new promissory note in the amount of $2,115,000 bearing 12% interest per annum and maturing on September 30, 2020 was issued. In addition to the promissory note, Dr. Schwartz received 50,000 shares of the Company’s common stock. All warrants issued under the prior promissory notes were cancelled under the exchange agreement; no rights and obligations remain under the cancelled notes. The Company determined that the exchange agreement had, in substance, occurred at December 31, 2019.

Effective as of April 21, 2020, the Company and Carl Schwartz, entered into an exchange agreement relating to a promissory note of the Company dated January 31, 2020 issued by the Company in the principal amount of $2,115,000. The note bore twelve percent (12%) interest per annum and had a maturity date of September 30, 2020. The accrued interest on the note through April 21, 2020 was $77,878, resulting in a total balance of $2,192,878 in principal and accrued interest on the Note as of such date. Dr. Schwartz and the Company agreed to exchange the note for newly issued shares of common stock of the Company at market value. Pursuant to the exchange agreement, Dr. Schwartz was issued 1,583,481 shares of newly issued common stock at an exchange rate of $1.43 per share, equal to the closing price of the common stock on April 21, 2020. Dr. Schwartz agreed (1) not to sell or otherwise transfer 766,740 shares for three months after the date of the exchange agreement, and (2) not to sell or otherwise transfer the remaining 766,741 shares for six months after the date of the exchange agreement. In 2021, the Company determined that due to a calculation error, the balance of the 2020 Schwartz Note should have been higher by $143,573 at the time of the exchange agreement, and on February 24, 2021, the Company issued an additional 100,401 shares to Dr. Schwartz.

April 2020 Paycheck Protection Program

On April 20, 2020, the Company entered into a promissory note with Park State Bank, which provides for an unsecured loan of $541,867 pursuant to the Paycheck Protection Program (the “PPP”) under the Coronavirus Aid, Relief, and Economic Security Act and applicable regulations (the “CARES Act”). The promissory note has a term of 2 years with a 1% per annum interest rate. Payments are deferred for 6 months from the date of the promissory note and the Company can apply for forgiveness of all or a portion of the promissory note after 60 days for covered use of funds.

Pursuant to the terms of the PPP, the promissory note, or a portion thereof, may be forgiven if proceeds are used for qualifying expenses as described in the CARES Act, such as payroll costs, costs used to continue group health care benefits, mortgage interest payments, rent and utilities. The Company has used all proceeds for qualifying expenses. The Company received forgiveness for the loan under the Paycheck Protection Program and recognized a gain in other income for the full amount of the loan during the fourth quarter of 2020.

NOTE 7 - DERIVATIVES

The Company concluded the September 2018 Investor Note contained a conversion feature which is an embedded derivative and required bifurcation. The embedded derivative’s value was determined using the discounted stock price for the 20-trading days preceding the balance sheet date and the assumption of conversion on that date, as management believed it was probable that the notes would be convertible based on management’s expectation that additional financing would be required. During the year ended December 31, 2020, the maximum number of conversions was reached. The Company recognized an unrealized gain for the corresponding change in fair value of $50,989 for the year ended December 31, 2020. The fair value of the derivative liability related to the bridge loan was zero as of December 31, 2020.

The Company concluded the Promissory Note 2020 contained a conversion feature and a put each of which was an embedded derivative and are required to be bifurcated. In accordance with ASC 815, Derivatives and Hedging, the Company combined these two embedded derivatives into a single derivative and determined the fair value to record within the derivative liability on the consolidated balance sheet. At inception, the fair value of the derivative liability was $68,796, $52,125 and $20,542 for the first, second and third tranches, respectively. During the year ended December 31, 2020, the Company recognized a gain of $87,923 on the change in the fair value of the derivative liability. As a result of the repayment of the note as of March 1, 2021, the embedded derivative had a fair value of zero prior to the repayment. The Company recorded a gain on the fair value of the derivative of $104,529 during the year ended December 31, 2021. As of December 31, 2020, the fair value of the derivative liability was $104,529.

The Company concluded the A, B and agent warrants issued in connection with the March 2020 Private Placement discussed above are a derivative liability due to certain features of the warrants which could, in certain circumstances, result in the holder receiving the Black Scholes value of the outstanding warrants in the same type of consideration as the common stockholders. As a result, in those circumstances, the amount of consideration would differ from that provided to holders of common stock, therefore, the warrants were classified as a liability. At inception, the A, B and agent warrants had a fair value of $2,669,995. During the third quarter of 2020, the A and B warrants were amended as discussed in Note 6 - Notes Payable above. As a result of this amendment, the warrants no longer represented a liability to the Company and were reclassified to equity. Prior to reclassification, a gain on the change in fair value of $700,910 was recorded during the year ended December 31, 2020. As of December 31, 2021, the fair value of the agent warrants was determined to be $41,336 and the Company recorded a loss on the change in fair value of $7,683 during the year ended December 31, 2021. As of December 31, 2020, the fair value of the agent warrants was determined to be $33,654 and the Company recorded a gain on the change in fair value of $69,479 during the year ended December 31, 2020.

F- 29

 

The Company concluded the warrants and agent warrants issued in connection with the May 2020 Offering discussed above are a derivative liability due to certain features of the warrants which could, in certain circumstances, result in the holder receiving the Black Scholes value of the outstanding warrants in the same type of consideration as the common stockholders. As a result, in those circumstances, the amount of consideration would differ from that provided to holders of common stock, therefore, the warrants were classified as a liability. At inception, the warrants and agent warrants had a fair value of $1,324,184. The Company recorded a loss on the change in fair value of the warrants of $460,065 during the year ended December 31, 2020. During June 2020, the investors exercised the warrants and exchanged the warrants for shares of common stock as discussed above. The fair value of the agent warrants was determined to be $33,819 and $42,646 as of December 31, 2021 and as of December 31, 2020, respectively. The Company recorded a loss on the change in fair value of the agent warrants of $8,827 during the year ended December 31, 2021 and a gain on the change in fair value of the agent warrants of $48,675 during the year ended December 31, 2020.

In connection with the June 2020 Warrant exercise and issuance, the Company concluded the warrants and agent warrants issued in connection with the June 2020 Warrant exercise and issuance, discussed above, are a derivative liability due to certain features of the warrants which could, in certain circumstances, result in the holder receiving the Black Scholes value of the outstanding warrants in the same type of consideration as the common stockholders. As a result, in those circumstances, the amount of consideration would differ from that provided to holders of common stock, therefore, the warrants were classified as a liability. At inception, the warrants and agent warrants had a fair value of $1,749,721. During the year ended December 31, 2020, the June warrants were amended. As a result of this amendment, the warrants no longer represented a liability to the Company and were reclassified to equity. Prior to reclassification, the Company recorded a gain on the change in fair value of the warrants of $834,520 during the year ended December 31, 2020. The Company recorded a loss on the change in fair value of the agent warrants of $12,797 during the year ended December 31, 2021 and a gain on the change in fair value of the agent warrants of $79,045 during the year ended December 31, 2020. The fair value of the agent warrants was $45,498 and $32,701 as of December 31, 2021 and as of December 31, 2020, respectively.

On September 30, 2020, the Promissory Note 2019 was amended. The Company concluded the Promissory Note 2019 contained a conversion feature which is an embedded derivative and is required to be bifurcated. In accordance with ASC 815, Derivatives and Hedging, the Company determined the fair value to record within the derivative liability on the consolidated balance sheet. At inception, the fair value of the derivative liability was $495,100. As a result of the repayment of the note as of March 1, 2021, the embedded derivative had a fair value of zero prior to the repayment. The Company recorded a gain on the fair value of the derivative of $89,680 during the year ended December 31, 2021. The Company recorded a gain on the change in fair value of the derivative liability of $405,420 during the year ended December 31, 2020. As of December 31, 2020, the fair value of the derivative liability was $89,680.

NOTE 9 – INCOME TAXES

The provision for income taxes consists of an amount for taxes currently payable and a provision for tax consequences deferred to future periods. Deferred income taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income 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.

F- 31

 

The Company recognized an income tax benefit of $661,658 in our consolidated statement of net loss related to the release of valuation allowance as a result of the zPREDICTA business combination. However, due to the cumulative operating losses, the Company determined that a 100% valuation allowance for the net deferred tax assets at December 31st is appropriate.

Actual income tax benefit differs from statutory federal income tax benefit as follows:

	Year Ended December 31,

The Company has determined, based upon its history, that it is probable that future taxable income may be insufficient to fully realize the benefits of the net operating loss (“NOL”) carryforwards and other deferred tax assets. As such, the Company has determined that a full valuation allowance is warranted. Future events and changes in circumstances could cause this valuation allowance to change.

F- 32

 

The acquired NOL carryforwards from zPREDICTA experienced an ownership change as defined in Section 382 of the Internal Revenue Code as a result of the merger. In addition, the Company experienced an ownership change in 2019 with the Helomics acquisition as well as December 2013. As a result, the ability to utilize the Company’s NOLs is limited. The Company may have experienced additional ownership changes since December 2013, but a formal study has not yet been performed. The general limitation rules allow the Company to utilize its NOLs subject to an annual limitation that is determined by multiplying the federal long-term tax-exempt rate by the Company’s value immediately before the ownership change.

At December 31, 2020, the Company had $297,735,754 of gross NOLs to reduce future federal taxable income, the majority of which are expected to be available for use in 2021, subject to the Section 382 limitation described above. The federal NOL’s of $261,455,216 expire beginning in 2022 if unused and $36,280,538 will carryforward indefinitely. The Company also had $222,290,524 of gross NOLs to reduce future state taxable income at December 31, 2020. The state NOL’s will expire beginning in 2021 if unused. The Company dissolved its Belgium subsidiary in 2020 and all carryforward tax losses will be eliminated on the final 2020 Belgium tax return filed. The Company's net deferred tax assets, which include the NOLs, are subject to a full valuation allowance. At December 31, 2020, the federal, state, and foreign valuation allowances were $59,913,739, $22,191,346, and $0, respectively.

At December 31, 2021, the Company had $308,990,822 of gross NOLs to reduce future federal taxable income, the majority of which are expected to be available for use in 2022, subject to the Section 382 limitation described above. The federal NOL’s of $259,490,005 expire beginning in 2023 if unused and $49,500,817 will carryforward indefinitely. The Company also had $227,277,399 of gross NOLs to reduce future state taxable income at December 31, 2021. The state NOL’s will expire beginning in 2022 if unused. The Company's net deferred tax assets, which include the NOLs, are subject to a full valuation allowance. At December 31, 2021, the federal and state valuation allowances were $62,034,750 and $23,145,374 respectively.

Tax years subsequent to 2001 remain open to examination by federal and state tax authorities due to unexpired net operating loss carryforwards.

The Company reviews income tax positions expected to be taken in income tax returns to determine if there are any income tax uncertainties. The Company recognizes tax benefits from uncertain tax positions only if it is more likely than not that the tax positions will be sustained on examination by taxing authorities, based on technical merits of the positions. The Company has identified no income tax uncertainties.

The Company recognizes interest and penalties on unrecognized tax benefits as well as interest received from favorable tax settlements within income tax expense. At December 31, 2021 and 2020, the Company recorded no accrued interest or penalties related to uncertain tax positions. 

NOTE 10 – Goodwill and Intangibles

Intangible Assets

Finite-lived intangible assets consist of patents and trademarks, licensing fees, developed technology, acquired software and customer relationships, and are amortized over their estimated useful life. Amortization expense was $374,328 and $313,709 in 2021 and 2020, respectively. Accumulated amortization is included in intangibles, net in the accompanying consolidated balance sheets. The Company reviews finite-lived identifiable intangible assets for impairment in accordance with ASC 360, Property, Plant and Equipment, whenever events or changes in circumstances indicate the carrying amount may not be recoverable. Events or changes in circumstances that indicate the carrying amount may not be recoverable include, but are not limited to, a significant change in the medical device marketplace and a significant adverse change in the business climate in which the Company operates.

F- 33

 

As of December 31, 2021, there were $3,962,118 in net intangibles as compared to $3,398,101 in net intangibles as of December 31, 2020.

The components of intangible assets were as follows:

	December 31, 2021										December 31, 2020
	Gross Carrying Costs		Accumulated Amortization			Impairment			Net Carrying Amount		Gross Carrying Costs		Accumulated Amortization			Net Carrying Amount

Impairment of Long-Lived Assets

The Company reviews long-lived assets, including property and equipment and intangible assets with estimable useful lives, for impairment whenever events or changes in circumstances indicate that the carrying amount of such an asset may not be recoverable.

The recoverability of an asset to be held and used is determined by comparing the carrying amount to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of the asset exceeded its estimated undiscounted future cash flows, the Company recorded an impairment charge in the amount by which the carrying amount of the asset exceeds its fair value, which is determined by either a quoted market price, if any, or a value determined by utilizing discounted cash flow techniques.

The Company prepared an undiscounted cash flow as of December 31, 2021 to evaluate long-lived assets based on a triggering event per ASC 360. The Company concluded that the undiscounted cash flows did not support the carrying values of its Helomics asset group at December 31, 2021. The Company determined the value of the intangibles and the software license acquired were fully impaired as of December 31, 2021 and recognized and impairment loss of $2,893,548 for its long-lived intangible assets and $1,249,727 for the acquired software. The Company concluded there was no impairment of its other finite lived tangible assets as of December 31, 2021. No impairment charges were incurred during 2020.

Goodwill

In accordance with ASC 350, Intangibles – Goodwill and Other, goodwill is calculated as the difference between the acquisition date fair value of the consideration transferred and the fair value of net assets acquired. Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination. Goodwill is an indefinite-lived asset and is not amortized. Goodwill is tested for impairment annually at the reporting unit level, or whenever events or circumstances present an indication of impairment.

F- 34

 

In the Helomics acquisition, the Company recorded goodwill of $23,790,290. The goodwill was recorded to the Helomics segment which represents a single reporting unit. As a part of the annual impairment testing as of December 31, 2019, the Company had the option to assess qualitative factors to determine if it was more likely than not that the carrying value of a reporting unit exceeded its estimated fair value. The Company believed a qualitative testing approach was not appropriate and, therefore, proceeded to the quantitative testing. When performing quantitative testing, the Company first estimated the fair value of the Helomics reporting unit using discounted cash flows. To determine fair values, the Company was required to make assumptions about a wide variety of internal and external factors. Significant assumptions used in the impairment analysis included financial projections of free cash flow (including significant assumptions about operations including the rate of future revenue growth, capital requirements, and income taxes), long-term growth rates for determining terminal value, and discount rates for the Helomics reporting unit. Comparative market multiples were also used to corroborate the results of the discounted cash flow test. These assumptions required significant judgment and actual results may differ from assumed and estimated amounts.

In testing goodwill for impairment as of September 30, 2020, the Company performed a quantitative impairment test, including computing the fair value of the Helomics reporting unit and comparing that value to its carrying value. Based upon the Company’s quantitative goodwill impairment test, the Company concluded that goodwill was impaired as of the testing date of September 30, 2020. Pursuant to ASU 2017-04, Simplifying the Test for Goodwill Impairment, the single step is to determine the estimated fair value of the reporting unit and compare it to the carrying value of the reporting unit, including goodwill. To the extent the carrying amount of goodwill exceeds the implied goodwill, the difference is the amount of the goodwill impairment. The quantitative review as of September 30, 2020 resulted in $2,997,000 of impairment expense related to goodwill.

When evaluating the fair value of Helomics reporting unit the Company used a discounted cash flow model and market comparisons. Key assumptions used to determine the estimated fair value included: (a) expected cash flow for the 20-year period following the testing date (including net revenues, costs of revenues, and operating expenses as well as estimated working capital needs and capital expenditures); (b) an estimated terminal value using a terminal year growth rate of 3.0% determined based on the growth prospects of the reporting unit; and (c) a discount rate of 25% based on management’s best estimate of the after-tax weighted average cost of capital. The discount rate included a Company specific risk premium of 10% for risks related to the term of the forecasts.

In testing goodwill for impairment as of December 31, 2020, the Company performed a quantitative impairment test, including computing the fair value of the Helomics reporting unit and comparing that value to its carrying value. Based upon the Company’s annual goodwill impairment test, the Company concluded that goodwill was impaired as of the testing date of December 31, 2020. The Company’s annual impairment test as of December 31, 2020 resulted in $9,879,498 of impairment expense related to goodwill.  A decrease in the growth rate of 0.5% or an increase of 0.5% to the discount rate would reduce the fair value of Helomics reporting unit by approximately an additional $588,000 and $988,000, respectively.  As of December 31, 2020, the cumulative impairment recorded was $20,976,498.

When evaluating the fair value of Helomics reporting unit the Company used a discounted cash flow model. Key assumptions used to determine the estimated fair value in 2020 included: (a) expected cash flow for the 10-year period following the testing date (including net revenues, costs of revenues, and operating expenses as well as estimated working capital needs and capital expenditures); (b) an estimated terminal value using a terminal year growth rate of 5.0% determined based on the growth prospects of the reporting unit; and (c) a discount rate of 14.0% based on management’s best estimate of the after-tax weighted average cost of capital. The discount rate included a Company specific risk premium of 1.0% for risks related to the term of the forecasts. The Company further used a probability weighting of various forecasts to address forecast risk.

F- 35

 

During the third quarter of 2021, the Company concluded that potential impairment indicators were present and that an impairment assessment was warranted for goodwill. In testing goodwill for impairment as of September 30, 2021, the Company performed a quantitative impairment test, including computing the fair value of the Helomics reporting unit and comparing that value to its carrying value. Based upon the Company’s quantitative goodwill impairment test, the Company concluded that goodwill was fully impaired as of September 30, 2021.

The quantitative review as of September 30, 2021 resulted in $2,813,792 of impairment expense related to goodwill. As of September 30, 2021, the cumulative impairment recorded was $23,790,290.

When evaluating the fair value of Helomics reporting unit the Company used a discounted cash flow model and market comparisons. Key assumptions used to determine the estimated fair value included: (a) expected cash flow for the 10-year period following the testing date (including net revenues, costs of revenues, and operating expenses as well as estimated working capital needs and capital expenditures); (b) an estimated terminal value using a terminal year growth rate of 4.0% determined based on the growth prospects of the reporting unit; and (c) a discount rate of 15% based on management’s best estimate of the after-tax weighted average cost of capital. The Company further used a probability weighting of various forecasts to address forecast risk.

Goodwill of $6,857,790 was recognized in the zPREDICTA acquisition and represents the excess of the consideration transferred over the fair values of assets acquired and liabilities assumed and represents the future economic benefits and synergies arising from the transaction. None of the goodwill will be deductible for income tax purposes. See Note 2 – zPREDICTA acquisition.

The following tables present changes in the carrying value of goodwill our consolidated balance sheet:

Goodwill balance at December 31, 2019	$	15,690,290
Impairment		(12,876,498	)
Goodwill balance at December 31, 2020	$	2,813,792
Impairment		(2,813,792	)
Acquisition of zPREDICTA		6,857,790
Goodwill balance at December 31, 2021	$	6,857,790

The majority of the inputs used in the discounted cash flow model are unobservable and thus are considered to be Level 3 inputs. The inputs for the market capitalization calculation are considered Level 1 inputs. The Company will continue to monitor its reporting units to determine whether events and circumstances warrant further interim impairment testing.

NOTE 13 – SEGMENTS

The Company has determined its reportable segments in accordance with ASC 280, Segment Reporting. Factors used to determine the Company’s reportable segments include the availability of separate financial statements, the existence of locally based leadership across geographic regions, the economic factors affecting each segment, and the evaluation of operating results at the segment level. The Chief Operating Decision Maker (“CODM”) allocates the Company’s resources for each of the reportable segments and evaluates their relative performance. Each reportable segment listed below has separate financial statements and locally based leadership that are evaluated based on the results of their respective segments. It should be noted that the reportable segments below have different products and services. The financial information is consolidated and evaluated regularly by the CODM in assessing performance and allocating resources.

During the third quarter of 2020, the Company considered, whether under ASC 280-10-50-3, there was a change in its reportable segments. As a result of the formation of the new Soluble subsidiary, the Company believes the Soluble business represents a reportable segment. Soluble signed its first contract during the third quarter of 2020. The Company also believes it is appropriate to combine our Skyline Medical and Skyline Europe entities into a single reportable segment based on the changes to our physical presence and intent to sign future contracts through the US entity. Finally, the Company believes the Helomics business continues to be a reportable segment.

The Company has four reportable segments: Helomics, zPREDICTA, Soluble and Skyline. See discussion of revenue recognition in Note 1 – Summary of Significant Accounting Policies for a description of the products and services recognized in each segment. The reported financial information below has been reclassified to conform to the current presentation. This information is intended to assist investors in making comparisons of the Company’s historical financial information with future financial information.

The table below summarizes the Company’s segment reporting as of and for years ended December 31, 2021 and 2020.

Exhibit 4.14

Description of Registrant’s Securities

As of March 25, 2022, Predictive Oncology Inc. (the “Company”) has one class of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), namely, our common stock, par value $0.01 per share (“Common Stock”).

Description of Common Stock

The following description of our Common Stock is a summary and does not purport to be complete. It is subject to and qualified in its entirety by reference to our Certificate of Incorporation, as amended (the “Certificate of Incorporation”), our Second Amended and Restated Bylaws, as amended (the “Bylaws”), and the Certificate of Designation of Preferences, Rights and Limitations applicable to each series of our Preferred Stock (as defined below) (collectively, the “Certificates of Designation”), each of which are incorporated by reference as an exhibit to the Annual Report on Form 10-K of which this Exhibit 4.1 is a part. We encourage you to read the Certificate of Incorporation, the Bylaws, the Certificates of Designation, and the applicable provisions of the General Corporation Law of the State of Delaware (the “DGCL”) for additional information.

Authorized Capital Stock. Our authorized capital stock consists of 200,000,000 shares of Common Stock, and 20,000,000 shares of preferred stock, $0.01 par value per share (“Preferred Stock”). Out of the Preferred Stock, as of December 31, 2021, 2,300,000 shares have been designated Series B Convertible Preferred Stock, of which 79,246 shares were outstanding

The outstanding shares of our Common Stock and Preferred Stock are fully paid and nonassessable.

The Series B Convertible Preferred Stock is convertible into Common Stock at the option of its holders on a 1:1 basis, subject to a 4.99% beneficial ownership blocker.

Blank Check Preferred Stock. Our Board of Directors is authorized, subject to any limitations prescribed by law, to provide for the issuance of the shares of Preferred Stock in series and, by filing a certificate pursuant to the applicable law of the State of Delaware, to establish from time to time the number of shares to be included in each such series, and to fix the designation, powers, preferences and rights of the shares of each such series and any qualifications, limitations or restrictions thereon. The number of authorized shares of Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the outstanding shares of Common Stock without a vote of the holders of the Preferred Stock, or of any series thereof, unless a vote of any such holders is required pursuant to the certificate or certificates establishing the series of Preferred Stock.

Voting Rights. The holders of our Common Stock are entitled to one vote for each outstanding share of Common Stock owned by that shareholder on every matter properly submitted to the shareholders for their vote. Shareholders are not entitled to vote cumulatively for the election of directors.

Dividend Rights. Subject to the dividend rights of the holders of any outstanding series of preferred stock, holders of our Common Stock are entitled to receive ratably such dividends and other distributions of cash or any other right or property as may be declared by our Board of Directors out of our assets or funds legally available for such dividends or distributions.

Liquidation Rights. In the event of any voluntary or involuntary liquidation, dissolution or winding up of our affairs, holders of our Common Stock would be entitled to share ratably in our assets that are legally available for distribution to shareholders after payment of liabilities and after the satisfaction of any liquidation preference owed to the holders of any Preferred Stock.

Conversion, Redemption and Preemptive Rights. Holders of our Common Stock have no conversion, redemption, preemptive, subscription or similar rights.

Bylaws. Certain provisions of our Bylaws could have anti-takeover effects. These provisions are intended to enhance the likelihood of continuity and stability in the composition of our corporate policies formulated by our Board of Directors. In addition, these provisions also are intended to ensure that our Board of Directors will have sufficient time to act in what our Board of Directors believes to be in the best interests of our Company and our shareholders. Nevertheless, these provisions could delay or frustrate the removal of incumbent directors or the assumption of control of us by the holder of a large block of Common Stock, and could also discourage or make more difficult a merger, tender offer, or proxy contest, even if such event would be favorable to the interest of our shareholders. These provisions are summarized below.

Advance Notice Provisions for Raising Business or Nominating Directors. Sections 2.09 and 2.10 of our Bylaws contain advance-notice provisions relating to the ability of shareholders to raise business at a shareholder meeting and make nominations for directors to serve on our Board of Directors. These advance-notice provisions generally require shareholders to raise business within a specified period of time prior to a meeting in order for the business to be properly brought before the meeting.

Number of Directors and Vacancies. Our Bylaws provide that the exact number of directors shall be determined from time to time solely by resolution adopted by the affirmative vote of a majority of the entire Board of Directors. The Board of Directors is divided into three classes, as nearly equal in number as possible, designated: Class I, Class II and Class III (each, a “Class”). In the case of any increase or decrease, from time to time, in the number of directors, the number of directors in each class shall be apportioned as nearly equal as possible. Except as otherwise provided in the Certificate of Incorporation, each director serves for a term ending on the date of the third annual meeting of the Company’s stockholders following the annual meeting at which such director was elected; provided, that the term of each director shall continue until the election and qualification of a successor and be subject to such director’s earlier death, resignation or removal. Vacancies on the Board of Directors resulting from death, resignation, removal or otherwise and newly created directorships resulting from any increase in the number of directors may be filled solely by a majority of the directors then in office (although less than a quorum) or by the sole remaining director.

Exhibit 10.5

PREDICTIVE ONCOLOGY INC.

STOCK OPTION AGREEMENT

(Employee)

This STOCK OPTION AGREEMENT (the “Agreement”) is made and entered into effective as of [●], between Predictive Oncology Inc., a Delaware corporation (the “Company”) and the undersigned employee (“Employee”).

BACKGROUND

A. Employee has either been hired to serve as an employee to the Company or the Company desires to induce Employee to continue to serve the Company as an employee.

B. The Company has adopted the Amended and Restated 2012 Stock Incentive Plan (the “Plan”), pursuant to which shares of common stock of the Company have been reserved for issuance under the Plan. Employee and the Company desire to enter into this Agreement for the granting of stock options.

NOW, THEREFORE, the parties hereto agree as follows:

1. Grant of Option; Purchase Price. Subject to the terms and conditions herein set forth, the Company hereby irrevocably grants to Employee the right and option, hereinafter called the “Option”, to purchase from the Company all or any part of any aggregate of [●] shares (the “Shares”) of common stock, $0.01 par value of the Company (the “Common Stock”). The purchase price of the Shares covered by the Option shall be $[●] per Share.

2. Exercise and Vesting of Option. The Option shall be exercisable only to the extent that all, or any portion thereof, has vested in Employee. Except as otherwise provided herein, the Option shall vest ratably over a period of eight (8) quarters in equal quarterly installments, beginning on [●], and continuing on the first quarter after the date of this Agreement and through each subsequent anniversary date (the “Vesting Date”) until the Option is fully vested, as set forth in the following schedule:

No. of Shares To Be Vested      Vesting Date

In the event that Employee ceases to be employed by the Company, for any reason or no reason, prior to any Vesting Date, that portion of the Option scheduled to vest on such Vesting Date, and all portions of the Option scheduled to vest in the future, shall not vest and all of Employee’s rights to and under such non-vested portions of the Option shall terminate.

3. Termination of Employment. Except as provided in Section 5 below, in the event that Employee ceases to be employed by the Company, for any reason or no reason, with or without cause, prior to any Vesting Date, that part of the Option scheduled to vest on such Vesting Date, and all parts of the Option scheduled to vest in the future, shall not vest and all of Employee’s rights to and under such non-vested parts of the Option shall terminate.

1

4. Term of Option. To the extent vested, and except as otherwise provided in this Agreement, the Option shall be exercisable for ten (10) years from the date of this Agreement; provided, however, that, except as provided in Section 5 below, in the event Employee or his/her legal representative shall have three (3) months from the date of such termination of his/her position as an employee to exercise any part of the Option vested pursuant to Section 2 of this Agreement. Upon the expiration of such three (3) month period, except as provided in Section 5 below, or, if earlier, upon the expiration date of the Option as set forth above, the Option shall terminate and become null and void.

5. Death of Employee. In the event of Employee’s death, the person designated in Employee’s will, or in the absence of such designation, Employee’s legal representative may, in like manner, exercise the Option to the extent of the number of Shares which were vested at the time of his/her death, but such right shall expire unless exercised by such designated person or legal representative, within the earlier of (i) six (6) months after the death of Employee, or (ii) the expiration of the Option.

6. Method of Exercising Option. Subject to the terms and conditions of this Agreement, the Option may be exercised, in whole or in part, by giving written notice to the Company, specifying the number of Shares to be purchased and accompanied by the full purchase price for such shares. Any such notice shall be deemed given when received by the Company at its corporate headquarters. The option price shall be payable (a) in United States dollars upon exercise of the option and may be paid by cash, uncertified or certified check or bank draft; (b) by delivery of shares of Common Stock in payment of all or any part of the option price, which shares shall be valued for this purpose at the Fair Market Value (as defined below) on the date such option is exercised; or (c) by instructing the Company to withhold from the Shares issuable upon exercise of the Option Shares in payment of all or any part of the exercise price and/or any related withholding tax obligations consistent with Section 13, which shares shall be valued for this purpose at the Fair Market Value or in such other manner as may be authorized from time to time by the Board of Directors. All Shares that shall be purchased upon the exercise of the Option as provided herein shall be fully paid and non-assessable.

7. Rights of Option Holder. Employee as holder of the Option, shall not have any of the rights of a shareholder with respect to the Shares covered by the Option except to the extent that one or more certificates for such Shares shall be delivered to him or her upon the due exercise of all or any part of the Option.

8. Limitations on Transferability. Except as otherwise provided below, the Option shall not be transferred, pledged or assigned other than by will or by the laws of decent and distribution, or pursuant to a qualified domestic relations order as defined by the Internal Revenue Code of 1986, as amended (the “Code”) or Title I of the Employee Retirement Income Security Act, or the rules there under, and the Company shall not be required to recognize any attempted assignment of such rights. Notwithstanding the preceding sentence, the Option may be transferred by Employee to Employee’s spouse, children, grandchildren or parents (collectively, the “Family Members”), to trusts for the benefit of Family Members, to partnerships or limited liability companies in which Family Members are the only partners or shareholders, or to entities exempt from federal income taxation pursuant to Section 501(c)(3) of the Code. During Employee’s lifetime, the Option may be exercised only by him or her, by his/her guardian or legal representative or by the transferees permitted by the preceding sentence.

2

9. No Continued Employment or Right to Corporate Assets. Nothing contained in this Agreement shall be deemed to grant Employee any right to continue in the employ of the Company for any period of time or to any right to continue his/her present or any other rate of compensation, nor shall this Agreement be construed as giving Employee, Employee’s beneficiaries or any other person any equity or interests of any kind in the assets of the Company or creating a trust of any kind or a fiduciary relationship of any kind between the Company and any such person.

10. Securities Law Matters. Employee acknowledges that the Shares to be received by him or her upon exercise of the Option may not have been registered under the Securities Act of 1933 or the Blue Sky laws of any state (collectively, the “Acts”). If such Shares have not been so registered, Employee acknowledges and understands that the Company is under no obligation to register, under the Acts, the Shares received by him or her or to assist him or her in complying with any exemption from such registration if he or she should at a later date wish to dispose of the Shares. Employee acknowledges that if not then registered under the Acts, the Shares shall bear a legend restricting the transferability thereof, such legend to be substantially in the following form:

“The shares represented by this certificate have not been registered or qualified under federal or state securities laws. The shares may not be offered for sales, sold, pledged or otherwise disposed of unless so registered or qualified, unless an exemption exists or unless such disposition is not subject to the federal or state securities laws, and the Company may require that the availability or any exemption or the inapplicability of such securities laws be established by an opinion of counsel, which opinion of counsel shall be reasonably satisfactory to the Company.”

11. Employee Representations. Employee hereby represents and warrants that Employee has reviewed with his/her own tax advisors the federal, state, and local tax consequences of the transactions contemplated by this Agreement. Employee is relying solely on such advisors and not on any statements or representation of the Company or any of its agents. Employee understands that he or she will be solely responsible for any tax liability that may result to him or her as a result of the transactions contemplated by the Agreement. The Option, if exercised, will be exercised for investment and not with a view to the sales or distribution of the Shares to be received upon exercise thereof.

12. Adjustment. In the event of any recapitalization, stock dividend, stock split, combination of shares or other change in the Common Stock, the number of Shares then subject to the Option shall be adjusted in proportion to the change in outstanding shares of Common Stock. In the event of any such adjustments, the purchase price of the Option shall be adjusted as and to the extent appropriate, in the discretion of the Board, to provide Employee with the same relative rights before and after the adjustment.

13. Withholding.

a. The Company shall have the right to withhold from or to collect as a condition of payment, any taxes required by law to be withheld. At any time when Employee is required to pay to the Company an amount required to be withheld under applicable income tax laws upon exercise of the Option, Employee may satisfy this obligation in whole or in part by electing (the “Election”) to have the Company withhold, from such Shares, shares of the Common Stock having a value up to the minimum amount of withholding taxes required to be collected on the transaction. The value of the shares to be withheld shall be based on the Fair Market Value of the Common Stock on the date that the amount of tax to be withheld shall be determined (Tax Date”).

3

b. Each Election must be made before the Tax Date. The Committee may disapprove of any Election, may suspend or terminate the right to make elections, or may provide with respect to the Option that the right to make Elections shall not apply to the Option. An Election is irrevocable.

14. Sale, Merger, Exchange or Liquidation. In the event of an acquisition of the Company through the sale of substantially all of the Company’s assets or through a merger, exchange, reorganization or liquidation of the Company or a similar event as determined by the Board (collectively a “transaction”), the Board shall be authorized, in its sole discretion, to take any and all action it deems equitable under the circumstances, including but not limited to any one or more of the following:

a. providing that the Option shall terminate and the Employee shall receive, in lieu of any Shares they would be entitled to receive under the vested portion of the Option, such stock, securities or assets, including cash, as would have been paid to Employee if the Option had been exercised and Employee had received Common Stock immediately before such transaction (with appropriate adjustment for the purchase price, if any).

b. providing that Employee shall receive, with respect to each share of Common Stock under the vested portion of the Option as of the effective date of any such transaction, at the determination of the Board, cash, securities or other property, or any combination thereof, in an amount equal to the excess, if any, of the Fair Market Value of such Common Stock on a date within ten days before the effective date of such transaction over the Option purchase price, and that the Option shall be cancelled.

c. providing Employee a substantially equivalent stock option (taking into account the transaction and the number of shares or other equity issued by such successor entity) with respect to the equity of the entity succeeding the Company by reason of such transaction.

d. providing that all unvested portions of the Option shall be void and deemed terminated, or, in the alternative, for the acceleration or waiver of the vesting of the Option.

The Board may restrict the rights of Employee under this Section 14 to the extent necessary to comply with Section 16(b) of the 1934 Act, the Internal Revenue Code of 1986, as amended, or any other applicable law or regulation. The grant of the Option shall not limit in any way the right or power of the Company to make adjustments, reclassifications, reorganizations or changes of its capital or business structure or to merge, exchange or consolidate or to dissolve, liquidate, sell or transfer all or any part of its business or assets.

15. Definition of Fair Market Value. For purposes of this Agreement, the “Fair Market Value” of a Share at a specified date shall be the amount which the Board of Directors determines in good faith to be 100% of the fair market value of such a share as of the date in question. Notwithstanding the foregoing:

a. If such shares are listed on a U.S. securities exchange, then the Fair Market Value shall be determined by reference to the last sale price of a Share on such U.S. securities exchange on the applicable date. If such U.S. securities exchange is closed for trading on such date, or if the Common Stock does not trade on such date, then the last sale price used shall be the one on the date the Common Stock last traded on such U.S. securities exchange.

4

b. If such shares are publicly traded but are not listed on a U.S. securities exchange, then Fair Market Value shall be determined by reference to the trading price of a share of Common Stock on such date (or, if the applicable market is closed on such date, the last date on which the Common Stock was publicly traded), be a method consistently applied by the Committee.

c. If such shares are not publicly traded, then the Committee’s determination will be based upon a good faith valuation of the Company’s Common Stock as of such date, which shall be based upon such factors as the Committee deems appropriate. The valuation shall be accomplished in a manner that complies with Code Section 409A.

16. General. 

a. The Option is granted pursuant to the Plan and is governed by the terms thereof. In the event of any conflict between the terms of this Agreement and the terms of the Plan, the terms of the Plan shall control. The Company shall at all times during the term of the Option reserve and keep available such number of Shares as will be sufficient to satisfy the requirements of this Agreement.

b. Nothing herein expressed or implied is intended or shall be construed as conferring upon or giving to any person, firm. Or corporation other than the parties hereto, any rights or benefits under or by reason of this Agreement.

c. Each party hereto agrees to execute such further documents as may be necessary or desirable to effect the purposes of this Agreement.

d. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original, but all of which shall constitute one and the same agreement.

Exhibit 10.6

PREDICTIVE ONCOLOGY INC.

NON-QUALIFIED STOCK OPTION AGREEMENT

(Executive)

This STOCK OPTION AGREEMENT (the “Agreement”) is made and entered into effective as of [●] between Predictive Oncology Inc., a Delaware corporation (the “Company”) and [●] (“Employee”).

BACKGROUND

A. Employee has either been hired to serve as an employee to the Company or the Company desires to induce Employee to continue to serve the Company as an employee.

B. The Company has adopted the Amended and Restated 2012 Stock Incentive Plan (the “Plan”), pursuant to which shares of common stock of the Company have been reserved for issuance under the Plan.

NOW, THEREFORE, the parties hereto agree as follows:

1. Grant of Option; Purchase Price. Subject to the terms and conditions herein set forth, the Company hereby irrevocably grants from the Plan to Employee the right and option, hereinafter called the “Option”, to purchase all or any part of an aggregate of the number of shares of common stock, $0.01 par value, of the Company (the “Shares”) set forth at the end of this Agreement after “Number of Shares” at the price per Share set forth at the end of this Agreement after “Purchase Price.”

2. Exercise and Vesting of Option. The Option shall be exercisable only to the extent that all, or any portion thereof, has vested in Employee. Except as provided herein in Sections 5 and 6 hereof, the Options shall vest in equal installments of [●] shares quarterly over two years, beginning on [●], with the last installment vesting on [●] (each such date is hereinafter referred to singularly as a “Vesting Date” and collectively as “Vesting Dates”), so long as Employee remains an employee of the Company.

3. Termination of Employment. Except as provided in Section 5 below, in the event that Employee ceases to be employed by the Company, for any reason or no reason, with or without cause, prior to any Vesting Date, that part of the Option scheduled to vest on such Vesting Date, and all parts of the Option scheduled to vest in the future, shall not vest and all of Employee's rights to and under such non-vested parts of the Option shall terminate.

4. Term of Option. To the extent vested, and except as otherwise provided in this Agreement, the Option shall be exercisable for ten (10) years from the date of this Agreement; provided, however, that, except as provided in Section 5 below, in the event Employee ceases to be employed by the Company, for any reason or no reason, Employee or his/her legal representative shall have three (3) months from the date of such termination of his/her position as an employee to exercise any part of the Option vested pursuant to Section 3 of this Agreement. Upon the expiration of such three (3) month period, except as provided in Section 5, or, if earlier, upon the expiration date of the Option as set forth above, the Option shall terminate and become null and void.

1

5. Termination of Employment. For certain definitions in this Section 5, reference is made to the Employment Agreement dated August 11, 2012, as amended on August 20, 2018, between the Employee and the Company (as it may be amended or restated from time to time, the “Employment Agreement”).

a. In the event of a termination of employment of Employee by the Company without Cause (as defined in the Employment Agreement) or by Employee for Good Reason (as defined in the Employment Agreement), (i) any unvested portion of the Option shall immediately vest, and (ii) the Option shall be exercisable until the earlier of (A) five (5) years after the date of such termination or (B) the expiration of the Option.

b. In the event of Employee’s voluntary termination of his employment or death on or after [●] (which will be considered his retirement age), (i) the entire Option shall immediately vest in full to the extent not already vested and (ii) the Option shall be exercisable by Employee or his estate or legal representative through the full remaining term of the Option.

c. In the event of Employee’s death, Employee’s estate or his legal representative, as the case may be, may exercise the Option to the extent of the number of Shares which were vested at the time of his death, but such right shall expire unless exercised by Employee’s estate or legal representative within the earlier of (i) twelve (12) months after the death of Employee, or (ii) the expiration of the Option.

6. Change in Control. “Change in Control” has the meaning provided in the Plan. Notwithstanding anything to the contrary contained herein, in the event of a Change in Control of the Company, the Option shall become fully vested upon the effective date of such event, and shall remain exercisable for the remainder of the term of the Option.

7. Method of Exercising Option. Subject to the terms and conditions of this Agreement and the Plan, the Option may be exercised, in whole or in part, by written notice to the Company. Such notice shall state the election to exercise the Option, the number of Shares in respect of which it is being exercised, the method of exercise, and shall be signed by the person or persons exercising the Option. The Employee may exercise the Option by (i) paying to the Company in cash the full exercise price; (ii) arranging for a broker to sell Shares and immediately thereafter pay to the Company the full exercise price; or (iii) delivering Shares previously owned by Employee, the total market value of which equals the full exercise. Applicable tax withholding may be paid by any method permitted under the Plan. Upon proper exercise, the Company shall deliver a certificate or certificates representing such Shares as soon as practicable after the notice shall be received. All Shares that shall be purchased upon the exercise of the Option as provided herein shall be fully paid and non-assessable.

8. Rights of Option Holder. Employee, as holder of the Option, shall not have any of the rights of a shareholder with respect to the Shares covered by the Option except to the extent that one or more certificates for such Shares shall be delivered to him or her upon the due exercise of all or any part of the Option.

2

9. Limitations on Transferability. The Option shall not be transferred, pledged or assigned except, in the event Employee's death, by will or the laws of descent and distribution to the limited extent provided in the Plan, or pursuant to a qualified domestic relations order as defined by the Internal Revenue Code of 1986, as amended (the “Code”) or Title I of the Employee Retirement Income Security Act, or the rules there under, and the Company shall not be required to recognize any attempted assignment of such rights. Notwithstanding the preceding sentence, the Option may be transferred by Employee to Employee's spouse, children, grandchildren or parents (collectively, the “Family Members”), to trusts for the benefit of Family Members, to partnerships or limited liability companies in which Family Members are the only partners or shareholders, or to entities exempt from federal income taxation pursuant to Section 501(c)(3) of the Code. During Employee's lifetime, the Option may be exercised only by him or her, by his/her guardian or legal representative or by the transferees permitted by the preceding sentence.

10. No Continued Employment or Right to Corporate Assets. Nothing contained in this Agreement shall be deemed to grant Employee any right to continue in the employ of the Company for any period of time or to any right to continue his/her present or any other rate of compensation, nor shall this Agreement be construed as giving Employee, Employee’s beneficiaries or any other person any equity or interests of any kind in the assets of the Company or creating a trust of any kind or a fiduciary relationship of any kind between the Company and any such person.

11. Securities Law Matters. Employee acknowledges that the Shares to be received by him or her upon exercise of the Option may not have been registered under the Securities Act of 1933 or the Blue Sky laws of any state (collectively, the “Acts”). If such Shares have not been so registered, Employee acknowledges and understands that the Company is under no obligation to register, under the Acts, the Shares received by him or her or to assist him or her in complying with any exemption from such registration if he or she should at a later date wish to dispose of the Shares. Employee acknowledges that if not then registered under the Acts, the Shares shall bear a legend restricting the transferability thereof, such legend to be substantially in the following form:

“The shares represented by this certificate have not been registered or qualified under federal or state securities laws. The shares may not be offered for sale, sold, pledged or otherwise disposed of unless so registered or qualified, unless an exemption exists or unless such disposition is not subject to the federal or state securities laws, and the Company may require that the availability or any exemption or the inapplicability of such securities laws be established by an opinion of counsel, which opinion of counsel shall be reasonably satisfactory to the Company.”

12. Employee Representations. Employee hereby represents and warrants that Employee has reviewed with his/her own tax advisors the federal, state, and local tax consequences of the transactions contemplated by this Agreement. Employee is relying solely on such advisors and not on any statements or representation of the Company or any of its agents. Employee understands that he or she will be solely responsible for any tax liability that may result to him or her as a result of the transactions contemplated by this Agreement. The Option, if exercised, will be exercised for investment and not with a view to the sale or distribution of the Shares to be received upon exercise thereof.

3

13. General.

a. The Option is granted pursuant to the Plan and is governed by the terms thereof. In the event of any conflict between the terms of this Agreement and the terms of the Plan, the terms of the Plan shall control. The Company shall at all times during the term of the Option reserve and keep available such number of Shares as will be sufficient to satisfy the requirements of this Agreement.

b. Nothing herein expressed or implied is intended or shall be construed as conferring upon or giving to any person, firm, or corporation other than the parties hereto, any rights or benefits under or by reason of this Agreement.

c. Each party hereto agrees to execute such further documents as may be necessary or desirable to affect the purposes of this Agreement.

d. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original, but all of which shall constitute one and the same agreement.

e. This Agreement, in its interpretation and effect, shall be governed by the laws of the State of Delaware applicable to contracts executed and to be performed therein.

Note 1 - Summary of Significant Accounting Policies

12 Months Ended

Notes to Financial Statements

Significant Accounting Policies [Text Block]

NOTE 1 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations and Continuance of Operations

Predictive Oncology Inc., (the “Company” or “Predictive” or “we”) filed with the Secretary of State of Delaware a Certificate of Amendment to its Certificate of Incorporation to change the corporate name to Predictive Oncology Inc. on June 10, 2019, trading under the new ticker symbol “POAI,” effective June 13, 2019.

The Company operates in four primary business areas: first, application of artificial intelligence (“AI”) in our precision medicine business, to provide AI-driven predictive models of tumor drug response to improve clinical outcomes for patients and to assist pharmaceutical, diagnostic, and biotech industries in the development of new personalized drugs and diagnostics primarily through its wholly owned subsidiary Helomics Holding Corporation (“Helomics”); second, tumor-specific in vitro models for oncology drug discovery and research through its newly acquired wholly-owned subsidiary, zPREDICTA; third, contract services and research focused on solubility improvements, stability studies, and protein production, primarily with our Soluble Biotech subsidiary, and; fourth, production of the United States Food and Drug Administration (“FDA”)-cleared STREAMWAY System for automated, direct-to-drain medical fluid waste disposal and associated products through its incorporated division Skyline.

The Company had cash and cash equivalents of $28,202,615 as of December 31, 2021. As of December 31, 2021, there was no outstanding debt. The Company believes that its existing capital resources will be sufficient to support its operating plan for the next twelve months and beyond. However, the Company may also seek to raise additional capital to support its growth through additional debt, equity or other alternatives or a combination thereof. The Company currently expects to use cash on hand to fund capital and equipment investments, research and development, potential acquisitions and its operations, and expects such sources to be sufficient to fund its requirements over that time.

Coronavirus Outbreak

The current COVID-19 worldwide pandemic has presented substantial public health challenges. In response to the crisis, emergency measures have been imposed by governments worldwide, including mandatory social distancing and the shutdown of non-essential businesses. These measures have adversely impacted the global economy, disrupted global supply chains and created significant volatility and disruption of financial markets, and our business and operations have been and will likely continue to be materially and adversely affected. For example, our contract manufacturer for the STREAMWAY® System has been forced to change locations, thereby delaying our order fulfillment for parts. We have also reduced on-site staff at several of our facilities, resulting in delayed production, less efficiency, and our sales staff is unable to visit with hospital administrators who are our customers and potential customers. In addition, COVID-19 has impacted the Company’s capital and financial resources, including our overall liquidity position and outlook. For instance, our accounts receivable has slowed while our suppliers continue to ask for pre-delivery deposits. Ultimately, the extent of the impact of the COVID-19 pandemic on our future operational and financial performance will depend on, among other matters, the duration and intensity of the pandemic; the level of success of global vaccination efforts; governmental and private sector responses to the pandemic and the impact of such responses on us; and the impact of the pandemic on our employees, customers, suppliers, operations and sales, all of which are uncertain and cannot be predicted. These factors may remain prevalent for a significant period of time even after the pandemic subsides, including due to a continued or prolonged recession in the U.S. or other major economies. Even in areas where "stay-at-home" restrictions, masking and social distancing measures have been lifted and the number of COVID-19 cases have declined, some jurisdictions may re-impose these measures as and if variant strains emerge or cases rise. The impacts of the COVID-19 pandemic, as with any adverse public health developments, could have a material adverse effect on our business, results of operations, liquidity or financial condition and heighten or exacerbate risks described in this Annual Report on Form 10-K.

Recently Adopted Accounting Standards

The Company considers the applicability and impact of all Accounting Standards Updates (“ASUs”) issued by the Financial Accounting Standards Board (the “FASB”). Recently issued ASUs not listed below either were assessed and determined to be not applicable or are currently expected to have no impact on the condensed consolidated financial statements of the Company.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses.” This ASU added a new impairment model (known as the current expected credit loss (“CECL”) model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses. The CECL model applies to most debt instruments, trade receivables, lease receivables, financial guarantee contracts, and other loan commitments. The CECL model does not have a minimum threshold for recognition of impairment losses and entities will need to measure expected credit losses on assets that have a low risk of loss. As a smaller reporting company pursuant to Rule 12b-2 of the Securities Exchange Act of 1934, as amended, these changes become effective for the Company on January 1, 2023. Management is currently evaluating the potential impact of these changes on the consolidated financial statements of the Company.

Accounting Policies and Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and disclosure of contingent assets and liabilities at the date of the financial statements and during the reporting period. Actual results could materially differ from those estimates.

Reclassifications

Certain reclassifications have been made to the prior years’ financial statements to conform to the current year presentation. The reclassifications had no effect on previously reported results of operations, cash flows or stockholders’ equity.

Cash and cash equivalents

The Company considers all highly liquid instruments with maturities when purchased of three months or less to be cash equivalents. The Company places its cash with high quality financial institutions and believes its risk of loss is limited to amounts in excess of that which is insured by the Federal Deposit Insurance Corporation.

Receivables

Receivables are reported at the amount the Company expects to collect on balances outstanding. The Company provides for probable uncollectible amounts through charges to earnings and credits to the valuation allowance based on management’s assessment of the current status of individual accounts.

Amounts recorded in accounts receivable on the consolidated balance sheet include amounts billed and currently due from customers. The amounts due are stated at their net estimated realizable value. An allowance for doubtful accounts is maintained to provide for the estimated amount of receivables that will not be collected. The Company reviews customers’ credit history before extending unsecured credit and establishes an allowance for uncollectible accounts based upon factors surrounding the credit risk of specific customers, historical trends and other information. Invoices are generally due 30 days after presentation. Accounts receivable over 30 days is generally considered past due. The Company does not accrue interest on past due accounts receivables. Receivables are written off once all collection attempts have failed and are based on individual credit evaluation and specific circumstances of the customer. The allowance for doubtful accounts balance was $0 as of both December 31, 2021 and 2020.

Fair Value Measurements

As outlined in Accounting Standards Codification (“ASC”) 820, Fair Value Measurement, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The accounting standards ASC 820 establishes a three-level fair value hierarchy that prioritizes information used in developing assumptions when pricing an asset or liability as follows:

Level 1 – Observable inputs such as quoted prices in active markets;

Level 2 – Inputs other than quoted prices in active markets, that are observable either directly or indirectly; and

Level 3 – Unobservable inputs where there is little or no market data, which requires the reporting entity to develop its own assumptions.

The Company uses observable market data, when available, in making fair value measurements. Fair value measurements are classified according to the lowest level input that is significant to the valuation.

The fair value of the Company’s investment securities, which consist of cash and cash equivalents, was determined based on Level 1 inputs. The fair value of the Company’s derivative liabilities and debt were determined based on Level 3 inputs. The Company generally uses Black Scholes method for determining the fair value of warrants classified as liabilities on a recurring basis. In addition, the Company uses the Monte Carlo method and other acceptable valuation methodologies when valuing the conversion feature and other embedded features classified as derivatives on a recurring basis. See Note 7 – Derivatives. When performing quantitative testing related to goodwill impairment analysis, the Company estimates the fair values of its reporting units using discounted cash flows. To determine fair values, the Company is required to make assumptions about a wide variety of internal and external factors. Significant assumptions used in the impairment analysis include financial projections of free cash flow (including significant assumptions about operations including the rate of future revenue growth, capital requirements, and income taxes), long-term growth rates for determining terminal value and discount rates. The majority of the inputs used in the discounted cash flow model are unobservable and thus are considered to be Level 3 inputs. See Note 10 – Goodwill and Intangibles.

The acquisition of zPREDICTA was accounted for as a business combination using the acquisition method of accounting. This method requires, among other things, that assets acquired and liabilities assumed be recognized at fair value as of the acquisition date. The fair value for the assets acquired and the liabilities assumed are based on information knowable and determined by management as of the acquisition date. The majority of the inputs used in the discounted cash flow model, the relief-from-royalty method under the income approach, the distributor method under the income approach and the multi-period excess earnings method under the income approach, each are unobservable and thus are considered to be Level 3 inputs. See Note 2 – zPREDICTA Acquisition.

Inventories

Inventories are stated at the lower of cost or net realizable value, with cost determined on a first-in, first-out basis.  

Fixed Assets

Fixed assets are stated at cost less accumulated depreciation. Depreciation of fixed assets is computed using the straight-line method over the estimated useful lives of the respective assets. Estimated useful asset life by classification is as follows: 

	Years
Computers, software and office equipment	3	-	10
Leasehold improvements (1)	2	-	5
Manufacturing tooling	3	-	7
Laboratory equipment	4	-	10
Demo equipment		3

(1) Leasehold improvements are amortized over the shorter of the useful life or the remaining lease term.

Upon retirement or sale of fixed assets, the cost and related accumulated depreciation or amortization are removed from the balance sheet and the resulting gain or loss is reflected in operations. Maintenance and repairs are charged to operations expense as incurred.

Long-lived Assets

Finite-lived intangible assets consist of patents and trademarks, licensing fees, developed technology, acquired software and customer relationships, and are amortized over their estimated useful life. Accumulated amortization is included in intangibles, net in the accompanying consolidated balance sheets.

The Company reviews finite-lived identifiable intangible assets for impairment in accordance with ASC 360, Property, Plant and Equipment, whenever events or changes in circumstances indicate the carrying amount may not be recoverable. Events or changes in circumstances that indicate the carrying amount may not be recoverable include, but are not limited to, a significant change in the medical device marketplace and a significant adverse change in the business climate in which the Company operates.

The Company prepared an undiscounted cash flow as of December 31, 2021 to evaluate long-lived assets based on a triggering event per ASC 360. The Company concluded that the undiscounted cash flows did not support the carrying values of its Helomics asset group at December 31, 2021. The Company determined the value of the intangibles and the software license acquired were fully impaired as of December 31, 2021 and recognized and impairment loss of $2,893,548 for its long-lived intangible assets and $1,249,727 for the acquired software. The Company concluded there was no impairment of its other finite lived tangible assets as of December 31, 2021. See Note 10 – Intangible Assets and Goodwill.

The Company also prepared an undiscounted cash flow as of December 31, 2020 to evaluate long-lived assets based on a triggering event at that time. The Company concluded that the undiscounted cash flows of the long-lived assets exceeded the carrying values. The Company concluded there was no impairment of its finite lived assets as of December 31, 2020.

Goodwill

In accordance with ASC 350, Intangibles – Goodwill and Other, goodwill is calculated as the difference between the acquisition date fair value of the consideration transferred and the fair value of net assets acquired. Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination. Goodwill is not amortized but is tested on an annual basis for impairment at the reporting unit level as of December 31, or whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable.

To determine whether goodwill is impaired, annually or more frequently if needed, the Company performs a multi-step impairment test. The Company first has the option to assess qualitative factors to determine if it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value. The Company may also elect to skip the qualitative testing and proceed directly to the quantitative testing. When performing quantitative testing, the Company first estimates the fair values of its reporting units using discounted cash flows. To determine fair values, the Company is required to make assumptions about a wide variety of internal and external factors. Significant assumptions used in the impairment analysis include financial projections of free cash flow (including significant assumptions about operations including the rate of future revenue growth, capital requirements, and income taxes), long-term growth rates for determining terminal value and discount rates. Comparative market multiples are used to corroborate the results of the discounted cash flow test. These assumptions require significant judgement. Pursuant to ASU 2017-04, Simplifying the Test for Goodwill Impairment, the single step is to determine the estimated fair value of the reporting unit and compare it to the carrying value of the reporting unit, including goodwill. To the extent the carrying amount of goodwill exceeds the implied goodwill, the difference is the amount of the goodwill impairment. The Company also completes a reconciliation between the implied equity valuation prepared and the Company’s market capitalization. The majority of the inputs used in the discounted cash flow model are unobservable and thus are considered to be Level 3 inputs. The inputs for the market capitalization calculation are considered Level 1 inputs. See Note 3 – Intangible Assets and Goodwill.

Leases – At inception of a contract a determination is made whether an arrangement meets the definition of a lease. A contract contains a lease if there is an identified asset and the Company has the right to control the asset. Operating leases are recorded as right-of-use (“ROU”) assets with corresponding current and noncurrent operating lease liabilities on our consolidated balance sheets. Financing leases are included within fixed assets with corresponding current liability within other current liabilities and noncurrent liability within other long-term liabilities on our consolidated balance sheets.

ROU assets represent our right to use an underlying asset for the duration of the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Recognition on the commencement date is based on the present value of lease payments over the lease term using an incremental borrowing rate. Leases with a term of 12 months or less at the commencement date are not recognized on the balance sheet and are expensed as incurred.

The Company has lease agreements with lease and non-lease components, which are accounted for as a single lease component for all asset classes. Leases are accounted for at a portfolio level when similar in nature with identical or nearly identical provisions and similar effective dates and lease terms.

Revenue Recognition

The Company recognizes revenue when it satisfies a performance obligation by transferring control of the promised goods or services to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Sales taxes are imposed on the Company’s sales to nonexempt customers. The Company collects the taxes from the customers and remits the entire amounts to the governmental authorities. Sales taxes are excluded from revenue and expenses.

Revenue from Product Sales

The Company has medical device revenue consisting primarily of sales of the STREAMWAY System, as well as sales of the proprietary cleaning fluid and filters for use with the STREAMWAY System. This revenue stream is reported within both the domestic and international revenue segments. The Company sells its medical device products directly to hospitals and other medical facilities using employed sales representatives and independent contractors. Purchase orders, which are governed by sales agreements in all cases, state the final terms for unit price, quantity, shipping and payment terms. The unit price is considered the observable stand-alone selling price for the arrangements. The Company sales agreement, and Terms and Conditions, is a dually executed contract providing explicit criteria supporting the sale of the STREAMWAY System. The Company considers the combination of a purchase order and acceptance of its Terms and Conditions to be a customer’s contract in all cases.

Product sales for medical devices consist of a single performance obligation that the Company satisfies at a point in time. The Company recognizes product revenue when the following events have occurred: (1) the Company has transferred physical possession of the products, (2) the Company has a present right to payment, (3) the customer has legal title to the products, and (4) the customer bears significant risks and rewards of ownership of the products. Based on the shipping terms specified in the sales agreements and purchase orders, these criteria are generally met when the products are shipped from the Company’s facilities (“FOB origin,” which is the Company’s standard shipping terms). As a result, the Company determined that the customer is able to direct the use of, and obtain substantially all of the benefits from, the products at the time the products are shipped. The Company may, at its discretion, negotiate different shipping terms with customers which may affect the timing of revenue recognition. The Company’s standard payment terms for its customers are generally 30 to 60 days after the Company transfers control of the product to its customer. The Company allows returns of defective disposable merchandise if the customer requests a return merchandise authorization from the Company.

Customers may also purchase a maintenance plan for the medical devices from the Company, which requires the Company to service the STREAMWAY System for a period of one year subsequent to the one-year anniversary date of the original STREAMWAY System invoice. The maintenance plan is considered a separate performance obligation from the product sale, is charged separately from the product sale, and is recognized over time (ratably over the one-year period) as maintenance services are provided. A time-elapsed output method is used to measure progress because the Company transfers control evenly by providing a stand-ready service. The Company has determined that this method provides a faithful depiction of the transfer of services to its customers.

All amounts billed to a customer in a sales transaction for medical devices related to shipping and handling, if any, represent revenues earned for the goods provided, and these amounts have been included in revenue. Costs related to such shipping and handling billing are classified as cost of goods sold. This revenue stream is reported under the Skyline reportable segment.

Revenue from Clinical Testing

Clinic diagnostic testing is comprised of our Tumor Drug Response Testing (ChemoFx) and Genomic Profiling (BioSpeciFx) tests. The Tumor Drug Response Testing test determines how a patient’s tumor specimen reacts to a panel of various chemotherapy drugs, while the Genomic Profiling test evaluates the expression and/or status of a particular gene related to a patient’s tumor specimen. Revenues are recognized when control of the promised goods or services is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The estimated uncollectible amounts are generally considered implicit price concessions that are a reduction in revenue. Helomics’ payments terms vary by the agreements reached with insurance carriers and Medicare. The Company’s performance obligations are satisfied at one point in time when test reports are delivered.

For service revenues, the Company estimates the transaction price which is the amount of consideration it expects to be entitled to receive in exchange for providing services based on its historical collection experience using a portfolio approach as a practical expedient to account for patient contracts as collective groups rather than individually. The Company monitors its estimates of transaction price to depict conditions that exist at each reporting date. If the Company subsequently determines that it will collect more consideration than it originally estimated for a contract with a patient, it will account for the change as an increase to the estimate of the transaction price, provided that such downward adjustment does not result in a significant reversal of cumulative revenue recognized.

The Company recognizes revenue from these patients when contracts as defined in ASC 606, Revenue from Contracts with Customers are established at the amount of consideration to which it expects to be entitled or when the Company receives substantially all of the consideration subsequent to the performance obligations being satisfied. The Company’s standard payment term for hospital and patient direct bill is 30 days after invoice date. This revenue stream is reported under the Helomics segment.

CRO Revenue

Contract revenues are generally derived from studies conducted with biopharmaceutical and pharmaceutical companies. The specific methodology for revenue recognition is determined on a case-by-case basis according to the facts and circumstances applicable to a given contract. The Company typically uses an input method that recognizes revenue based on the Company’s efforts to satisfy the performance obligation relative to the total expected inputs to the satisfaction of that performance obligation. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation on the basis of the standalone-selling price of each distinct good or service in the contract. Advance payments received in excess of revenues recognized are classified as deferred revenue until such time as the revenue recognition criteria have been met. Payment terms are net 30 from the invoice date, which is sent to the customer as the Company satisfies the performance obligation relative to the total expected inputs to the satisfaction of that performance obligation. This revenue stream is reported under the Helomics and zPREDICTA segments.

Variable Consideration

The Company records revenue from distributors and direct end customers in an amount that reflects the transaction price it expects to be entitled to after transferring control of those goods or services. The Company’s current contracts do not contain any features that create variability in the amount or timing of revenue to be earned.

Warranty

The Company generally provides one-year warranties against defects in materials and workmanship on product sales and will either repair the products or provide replacements at no charge to customers. As they are considered assurance-type warranties, the Company does not account for them as separate performance obligations. Warranty reserve requirements are based on a specific assessment of the products sold with warranties where a customer asserts a claim for warranty or a product defect. 

Contract Balances

The Company records a receivable when it has an unconditional right to receive consideration after the performance obligations are satisfied. As of December 31, 2021 and 2020, accounts receivable totaled $354,196 and $256,878, respectively.

The Company’s deferred revenues related primarily to our zPREDICTA contract research revenue and maintenance plans of our Skyline Medical operating segment. As of December 31, 2021 and 2020, deferred revenue was $186,951 and $53,028, respectively.

Practical Expedients

The Company has elected the practical expedient not to determine whether contracts with customers contain significant financing components as well as the practical expedient to recognize shipping and handling costs at point of sale.

Valuation and accounting for stock options and warrants

The Company determines the grant date fair value of options and warrants using a Black-Scholes option valuation model based upon assumptions regarding risk-free interest rate, expected dividend rate, volatility and estimated term.

The fair value of each option and warrant grant is estimated on the grant date using the Black-Scholes option valuation model with the following assumptions:

	For the Year Ended December 31,
	2021			2020
	Stock Options
Expected dividend yield		0.0%			0.0%
Expected stock price volatility	84.8%	-	89.6%	82.6%	-	87%
Risk-free interest rate	0.93%	-	1.66%	0.13%	-	1.78%
Expected life (years)		10			10
	Warrants
Expected dividend yield		0.0%			0.0%
Expected stock price volatility		84.8%		82.6%	-	87%
Risk-free interest rate	0.42%	-	0.69%	0.135%	-	0.79%
Expected life (years)	5/		5.5	5/		5.5

Research and Development

Research and development costs are charged to operations as incurred. Research and development costs were $315,850 and $372,710 for the years ended 2021 and 2020, respectively.

Other Expense

Other expense consisted primarily of interest expense, payment penalties, amortization of original issue discounts, and loss on debt extinguishment associated to the Company’s notes payable.

Offering Costs

Costs incurred which are direct and incremental to an offering of the Company’s securities are deferred and charged against the proceeds of the offering, unless such costs are deemed to be insignificant in which case they are expensed as incurred.

Income Taxes

The Company accounts for income taxes in accordance with ASC 740, Income Taxes (“ASC 740”). Under ASC 740, deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities and net operating loss and credit carryforwards using enacted tax rates in effect for the year in which the differences are expected to impact taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized.

The Company reviews income tax positions expected to be taken in income tax returns to determine if there are any income tax uncertainties. The Company recognizes tax benefits from uncertain tax positions only if it is more likely than not that the tax positions will be sustained on examination by taxing authorities, based on technical merits of the positions. The Company has identified no income tax uncertainties.

Under Internal Revenue Code Section 382, certain stock transactions which significantly change ownership could limit the amount of net operating carryforwards that may be utilized on an annual basis to offset taxable income in future periods. The Company has not yet performed an analysis of the annual net operating loss carryforwards and limitations that are available to be used against taxable income. Consequently, the limitation, if any, could result in the expiration of the Company’s loss carryforwards before they can be utilized. The Company has not analyzed net operating loss carryforwards under Section 382 to date. As a result of the Helomics acquisition, there may be significant limitation to the net operating loss. In addition, the current NOL carryforwards might be further limited by future issuances of our common stock.

Tax years subsequent to 2001 remain open to examination by federal and state tax authorities due to unexpired net operating loss carryforwards.

Credit Risk

Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash. The Company places its cash with high credit quality financial institutions and, by policy, generally limits the amount of credit exposure to any one financial institution. As of December 31, 2021. the Company did not have credit risk for cash amounts held in a single institution that are in excess of amounts issued by the Federal Deposit Insurance Corporation.

Risks and Uncertainties

The Company is subject to risks common to companies in the medical device and biopharmaceutical industries, including, but not limited to, development by the Company or its competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, and compliance with regulations of the Food and Drug Administration, Clinical Laboratory Improvement Amendments, and other governmental agencies.

The Company has evaluated all of its activities and concluded that no other subsequent events have occurred that would require recognition in the consolidated financial statements or disclosure in the notes to the consolidated financial statements, except as described above and in Note 16 – Subsequent Events.

Business Combination Disclosure [Text Block]

NOTE 2 – zPREDICTA ACQUISITION

On November 24, 2021, the Company entered into an Agreement and Plan of Merger (the “Agreement”) among the Company, a wholly-owned subsidiary of the Company (the “Merger Sub”), zPREDICTA, and a representative for certain parties who held interests in zPREDICTA. Also on November 24, 2021, the Company acquired zPREDICTA through the merger of Merger Sub with and into zPREDICTA, with zPREDICTA surviving as a wholly-owned subsidiary of the Company.

As consideration for the acquisition, the stockholders and certain holders of interests in zPREDICTA as of immediately prior to the transaction collectively received consideration of approximately $10.0 million in cash. The Agreement contains customary and negotiated representations, warranties, and indemnity provisions.

The acquisition costs of $895,297 related to the acquisition are presented in legal, accounting and consulting expenses within general and administrative expenses in the accompanying consolidated statements of net loss.

The following table summarizes the acquisition date fair values of assets acquired and liabilities assumed, and the consideration transferred:

Cash consideration	$	10,015,941
Assets acquired:
Cash		425,727
Accounts receivable		76,549
Prepaid expenses		25,733
Intangible assets		3,780,000
Liabilities assumed:
Accrued expenses		(408,825	)
Deferred tax liability		(661,658	)
Deferred revenue		(79,375	)
Goodwill	$	6,857,790

The purchase price allocation has been derived from estimates. The Company’s judgements used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed can materially affect the consolidated operations of the consolidated Company. The total purchase price has been allocation to identifiable assets acquired and liabilities assumed based upon valuation studies and procedures performed to date. The fair value and useful life for the intangible assets are (a) tradename $80,000 b) developed technology $3,500,000 and c) customer relationships $200,000 with useful lives of 4 years, 10 years and 10 years, respectively all using a straight-line method.

The Company acquired zPREDICTA through a non-taxable reverse triangular merger combination. As part of purchase accounting there was $3,780,000 in fair value assigned to purchased intangibles which the Company established a related deferred tax liability as a result of the stock merger combination that offset the acquired deferred assets including NOL’s and other temporary timing differences.

Identifiable Intangible Assets

The Company acquired intangible assets related to trademarks for the acquired zPREDICTA trade name with an estimated fair market value of $80,000. The fair values of the asset were determined by the relief-from-royalty method under the income approach. The Company determined the asset is a finite lived asset. The useful life of the tradename has a remaining useful life of 4 years as of December 31, 2021.

The Company acquired intangible assets with a useful life of 10 years and an estimated value of $200,000 related to customer relationships stemming from stable and predictable cash flow streams associated with customers. zPREDICTA’s customer base includes contract research partnerships with pharmaceutical, diagnostic, biotechnology, and research companies. The customer relationships were valued using the distributor method under the income approach.

The Company acquired intangible assets with a useful life of 10 years and an estimated value of $3,500,000 related to developed technology stemming from the 3D tumor model technology. Since the model technology was identified as the primary asset, this technology was valued using the multi-period excess earnings method under the income approach.

Goodwill

Goodwill of $6,857,790 was recognized in the zPREDICTA acquisition and represents the excess of the consideration transferred over the fair values of assets acquired and liabilities assumed and represents the future economic benefits and synergies arising from the transaction. None of the goodwill will be deductible for income tax purposes. See Note 10 – Goodwill and Intangibles.

Financial Results

The financial results of zPREDICTA since the acquisition date have been included in the Company’s accompanying consolidated statements of net loss.

Pro Forma

The following pro forma information presents the combined results of operations of the Company and zPREDICTA as if the acquisition of zPREDICTA had been completed on January 1, 2020, with adjustments to give effect to pro forma events that are directly attributable to the acquisition.

	2021			2020
	Unaudited			Unaudited
Revenue	$	2,429,786		$	1,815,560
Net loss attributable to common shareholders	$	(18,878,432	)	$	(26,946,564	)

The primary adjustments include the inclusion of the revalued amortization for zPREDICTA intangible assets. The unaudited pro forma results do not reflect any operating efficiencies or potential cost savings which may result from the consolidation of operations. Accordingly, these unaudited pro forma results are presented for informational purposes only and are not necessarily indicative of what the actual results of operations of the combined company would have been if the acquisition had occurred at the beginning of those respective time periods, nor are they indicative of future results of operations.

There are certain portions of purchase accounting, specifically Section 382 for Tax Loss Carryforwards, which take place after a company has undergone a shift in ownership, that the Company has not completed yet and may have a significant impact on the financial statements.

Authorized Shares

At the special meeting on August 17, 2021, the stockholders approved a proposal to increase the number of authorized shares of common stock to 200,000,000 shares of common stock, $0.01 par value. The amendment to the certificate of incorporation to affect this increase was filed on August 17, 2021.

2021 Offerings

In January and February 2021, the Company completed a series of five offerings, all of which were priced at-the-market under applicable NASDAQ rules. The first four offerings were registered direct offerings of common stock under its shelf registration statement, and in each such case, in a concurrent private placement, the Company also issued such investors one warrant to purchase common stock for each two shares purchased in the transaction. Following those four offerings, the Company completed a private placement of common stock, with each investor receiving one warrant to purchase common stock for each two shares purchased in the transaction. In June 2021, the Company completed a registered direct offering of common stock and warrants. The warrants became exercisable on the effective date of an increase in the number of shares of the Company’s authorized common stock, which occurred on August 17, 2021, and expire three years after the initial exercise date. In each case, each such investor warrant is exercisable immediately upon issuance and will expire five and one-half years from the issue date. In each case, the Company paid to the placement agent an aggregate fee equal to 7.5% of the aggregate gross proceeds received by the Company in the offering and a management fee equal to 1% of the aggregate gross proceeds received by the Company in the offering and reimbursed the placement agent for certain non-accountable and out-of-pocket expenses. In addition, the Company granted to the placement agent, or its assigns warrants to purchase 7.5% of the shares sold to investors in the offering at an exercise price equal to 125% of the price of the shares in the transaction, with a term of five years for the registered direct offerings (three years for the June 2021 offering) or five and one-half years for the private placement.

These 2021 offerings were as follows:

2021 Warrant Exercises

During the year ended December 31, 2021, the holders of outstanding investor warrants have exercised such warrants for the total purchase of 5,269,059 shares at a weighted average exercise price of $0.86 per share, for total proceeds of $4,513,871.

Equity Line

On October 24, 2019, the Company entered into an equity purchase agreement with an investor, providing for an equity financing facility. Upon the terms and subject to the conditions in the purchase agreement, the investor is committed to purchase shares having an aggregate value of up to $15,000,000 of the Company’s common stock for a period of up to three years. The Company issued to the investor 104,651 commitment shares at a fair market value of $450,000 for entering into the agreement. From time to time during the three-year commitment period, provided that the closing conditions are satisfied, the Company may provide the investor with put notices to purchase a specified number of shares subject to certain limitations and conditions and at specified prices, which generally represent discounts to the market price of the common stock. During the year ended December 31, 2020, the Company issued 4,231,073 shares of common stock valued at $4,891,348 pursuant to the equity line. As of December 31, 2021, there was $9,113,829 of remaining available balance under the equity line, subject to shareholder approval required for additional purchases, as well as requirements for market conditions including trading volume and stock price, and subject to other limitations. During the year ended December 31, 2021, the Company issued 647,504, shares of its common stock valued at $675,590 pursuant to the equity line.

Series D Preferred Stock

In April 2019, the Company issued 3,500,000 shares of Series D preferred stock to Helomics as part of its acquisition of Helomics. Each share of Series D preferred stock is subject to automatic conversion, whereby each such share converts automatically on a 10:1 basis into a share of the Company’s common stock upon the earlier of (1) the consummation of any fundamental transaction (e.g., a consolidation or merger, the sale or lease of all or substantially all of the assets of Predictive or the purchase, tender or exchange offer of more than 50% of the outstanding shares of voting stock of Predictive,) or (2) the one-year anniversary of the issuance date. On April 4, 2020, 3,500,000 shares of Series D convertible preferred stock were converted into 350,004 shares of common stock.

Series E Convertible Preferred Stock

In June through September 2019, the Company entered into a private placement securities purchase agreement with investors for shares of Series E convertible preferred stock. The Company issued 258 preferred shares. Each preferred shareholder had the right to convert each Series E convertible preferred share into 0.056857% of the issued and outstanding shares of common stock immediately prior to conversion for each share of Series E convertible stock, beginning six months after the initial close date of June 13, 2019. On the date that is 12 months after the initial closing date, the Company has the option to convert the preferred shares into common stock upon the same terms and limitations as the above optional conversion. The preferred shares included a contingent beneficial conversion amount of $289,935, representing the intrinsic value of the shares at the time of issuance. The Company determined the Series E convertible preferred stock should be classified as permanent equity and the beneficial conversion feature amount was accreted through the earliest redemption date of December 13, 2019.

During the first quarter of 2020, 50 shares of Series E convertible preferred stock were converted into 141,191 shares of common stock. In May 2020, we notified the holders of our Series E Convertible Preferred Stock of our election to convert the outstanding shares of Series E Stock into common stock effective on June 13, 2020 pursuant to the terms of the Series E Stock. Prior to the conversion, there were 207.7 shares of Series E Stock outstanding. Each share of Series E Stock converted into 0.056857% of the issued and outstanding shares of common stock immediately prior to conversion; therefore, the 207.7 outstanding shares of Series E Stock on June 13, 2020 converted into 1,257,416 shares of common stock equal to 11.8% of the outstanding shares of common stock as of June 12, 2020.

March 2020 Private Placement

On March 18, 2020, we sold and issued to private investors (i) 260,000 shares of common stock, at a sale price of $2.121 per share; (ii) prefunded warrants to acquire 1,390,166 shares of common stock, sold at $2.12 per share and exercisable at an exercise price of $0.001 per share; (iii) Series A warrants to acquire 1,650,166 shares of Common Stock at $1.88 per share, exercisable immediately and terminating five and one-half years after the date of issuance; and (iv) Series B warrants to acquire 1,650,166 shares of Common Stock at $1.88 per share, exercisable immediately and terminating two years after the date of issuance. See below for amendment dated September 23, 2020.

In addition, and in lieu of common shares, the investors also purchased prefunded warrants to purchase 1,390,166 shares of common stock at a purchase price of $2.12 per prefunded warrant, which represents the per share offering price, minus the $0.0001 per share exercise price of each such prefunded warrant. As a result of the prefunded warrants exercise price being of a nominal amount, these warrants were included as outstanding shares within our earnings per share calculation during the period from purchase through to exercise during the second quarter 2020.

The sale of the offering shares, prefunded warrants and A and B warrants resulted in gross proceeds of $3,498,612 and net proceeds of $3,127,818 after deducting the placement agent fees and estimated offering expenses payable by the Company. The Company agreed to use the net proceeds from the offering for general corporate purposes. The offering closed on March 18, 2020, subject to the satisfaction of customary closing conditions.

Effective September 23, 2020, the Company amended the terms of A and B warrants. Earlier in September, the Company notified the holders of the warrants that the Company would accept an exercise price therefor of $0.8457, amended from the original exercise price of $1.88 per share. The amendment also modified the settlement provisions of the warrants under certain circumstances; this change resulted in a classification change from derivative liability to equity classification. See Note 7 –– Derivatives for discussion of A, B and agent warrants accounted for as derivative liabilities prior to September 23, 2020.

Dr. Schwartz Note Exchange

Effective as of April 21, 2020, the Company and Carl Schwartz, entered into an exchange agreement relating to a promissory note of the Company dated January 31, 2020 issued by the Company in the principal amount of $2,115,000. Pursuant to the exchange agreement, Dr. Schwartz was issued 1,583,481 shares of newly issued common stock at an exchange rate of $1.43 per share. See Note 5 – Notes Payable.

May 2020 Registered Direct Offering and Concurrent Private Placement of Warrants

During May 2020, the Company entered into a securities purchase agreement with certain accredited investors for a registered direct offering of 1,396,826 shares of common stock, par value $0.01 per share. In a concurrent private placement, the Company also issued such investors warrants to purchase up to an aggregate of 1,396,826 shares of common stock. The shares and the warrants were sold at a combined offering price of $1.575 per share and associated warrant. Each warrant is exercisable immediately upon issuance at an exercise price of $1.45 per share and will expire five and one-half years from the issue date. The sale of the offering shares and associated warrants resulted in gross proceeds of $2,200,001 and net proceeds of $1,930,100 after deducting the placement agent fees and offering expenses payable by the Company. The Company used the net proceeds from the offering to repay certain indebtedness and agreed to use the remaining net proceeds from the offering for general corporate purposes. The offering closed on May 8, 2020.

Acquisition from Soluble Therapeutics and BioDtech

On May 27, 2020, the Company entered into an Asset Purchase Agreement with InventaBioTech, Inc. (“InventaBioTech”) and two of its subsidiaries, Soluble Therapeutics, Inc. (“Soluble”), and BioDtech, Inc. (“BioDtech”), and simultaneously completed the acquisition of substantially all of Soluble’s and BioDtech’s assets. In exchange, the Company issued 125,000 shares of common stock and waived all existing claims that the Company has or may have against InventaBioTech (f/k/a CytoBioscience, Inc.), including the nonpayment of $1,290,000 owing by InventaBioTech to the Company. All of the shares issued in the acquisition were deposited into escrow, with 25,000 released upon the six-month anniversary of the closing, 25,000 released upon the nine-month anniversary of the closing, and the remaining shares released on May 26, 2021. Notwithstanding the foregoing, all or some of the escrow shares may be released and returned to the Company for reimbursement in the event that the Company suffers a loss against which InventaBioTech, Soluble, and BioDtech have indemnified the Company pursuant to the Agreement. The Company is also entitled to reclaim 10,000 of the shares if, within six months of the closing, the Company is unable to successfully obtain ownership of all of Soluble’s interest under its license agreement with the UAB Research Foundation. As a result of the acquisition, which was treated as an asset acquisition, the Company recognized fixed assets of $1,492,500.

June 2020 Warrant exercise and issuance

During June 2020, the Company entered into an agreement with certain accredited institutional investors to immediately exercise for cash an aggregate of 1,396,826 of the warrants issued in connection with the May 2020 Registered Direct Offering, exercisable immediately at the exercise price of $1.45 per share of common stock plus an additional $0.125 for each new warrant to purchase up to a number of shares of common stock equal to 100% of the number of shares issued pursuant to the exercise of the existing warrants. The new warrants are exercisable immediately and have a term of five and one-half years and an exercise price per share equal to $1.80. The Company received $2,130,701 in gross proceeds and net proceeds of $1,865,800 after deducting the placement agent fees and offering expenses payable by the Company.

Effective on September 23, 2020, the Company amended the terms of warrants to purchase up to 1,396,826 shares of the Company’s common stock, par value $0.01 per share. The amendment modified the settlement provisions of the warrants under certain circumstances; this change resulted in a classification change from derivative liability to equity classification.

Acquisition of Quantitative Medicine

On July 1, 2020, the Company entered into an Asset Purchase Agreement with Quantitative Medicine LLC (“QM”), a Delaware limited liability company and its owners and simultaneously completed the acquisition of substantially all of QM’s assets owned by Seller. QM is a biomedical analytics and computational biology company that developed a novel, computational drug discovery platform called CoRE. CoRE is designed to dramatically reduce the time, cost, and financial risk of discovering new therapeutic drugs by predicting the main effects of drugs on target molecules that mediate disease. In exchange for QM’s assets, including CoRE, the Company provided consideration in the form of 954,719 shares of common stock, which, when issued, had a fair value of $1,470,267. One half of the shares issued, or 477,359 shares were deposited and held in escrow upon issuance, while 207,144 of the remaining shares were issued to Carnegie Mellon University (“CMU”) in satisfaction of all pre-closing amounts owed to CMU under a technology licensing agreement that was assumed by the Company on the closing date. Half of the shares held in escrow were released on the six-month anniversary of the closing date, and the other half was released on the one-year anniversary of the closing date.

Warrants Issued in Connection with Helomics Acquisition         

Effective on September 14, 2020, the Company amended the terms of warrants to purchase up to 1,424,506 shares of the Company’s common stock, par value $0.01 per share, which were issued to certain holders in connection with the Company’s merger transaction with Helomics on April 4, 2019. In September 2020, the Company notified the holders of the warrants that the Company will accept an exercise price of $0.845, equal to the last reported per share price of Common Stock on the NASDAQ Capital Market on September 11, 2020, amended from the original exercise price of $10.00 per share (as adjusted for a one-for-ten (1:10) reverse stock split that was effective on October 29, 2019). The value of the amendment was determined based on the increase in the fair value on the date of modification using the Black Scholes method and equaled $554,287. The amendment was accounted for as a deemed dividend and increased the loss attributable to the common shareholders when calculating earnings per share. The Warrants were issued on April 4, 2019 to holders of warrants in Helomics; the Warrants expire on April 4, 2024. See Note 8 – Loss per Share.

Equity Incentive Plan

The Company has an equity incentive plan, which allows issuance of incentive and non-qualified stock options, stock appreciation rights, stock awards, restricted stock, restricted stock units and performance awards to employees, directors and consultants of the Company, where permitted under the plan. The exercise price for each stock option is determined by the market price on the date of issuance. Vesting requirements are determined by the Board of Directors when granted and currently range from immediate to three years. Options outstanding under this plan have a contractual life of ten years.

At the special meeting on August 17, 2021, the stockholders approved a proposal to increase the reserve shares of common stock authorized for issuance under the Amended and Restated 2012 Stock Incentive Plan by 1,500,000 to 3,250,000 reserve shares.

Options and Warrants

ASC 718, Compensation – Stock Compensation, (“ASC 718”) requires that a company that issues equity as compensation needs to record compensation expense on its statements of net loss that corresponds to the estimated cost of those equity grants. ASC 718 requires companies to estimate the fair value of stock-based payment awards on the date of grant using an option-pricing model or other acceptable means.

The Company determines the grant date fair value of options and warrants using a Black-Scholes option valuation model based upon assumptions regarding risk-free interest rate, expected dividend rate, volatility and estimated term. See Note 1 – Summary of Significant Accounting Policies – Accounting Policies and Estimates.

Secured Notes and Repayment in Full

In September 2018, the Company issued convertible secured promissory notes to two private investors in the original principal amount of an aggregate $2,297,727 (together, the “2018 Investor Note”) in exchange for cash proceeds of $2,000,000. As additional consideration for the 2018 Investor Note, the Company issued an aggregate 65,000 shares of its common stock as inducement shares plus warrants to acquire up to an aggregate 107,178 shares of common stock at an exercise price of $11.55 per share. Pursuant to a security agreement between the Company and the investors, the Company granted to the investors a security interest in its assets to secure repayment of the note. The 2018 Investor Note accrued interest at a rate of 8% per annum. In February 2019, the Company entered into a forbearance agreement with the 2018 Investor Note investors pursuant to which, among other things, the investors agreed to forbear on their rights to accelerate the 2018 Investor Note based on an event of default and a claimed event of default. In connection with such forbearance, an additional $344,659 in principal and an additional 16,667 common shares were issued to the investors. In September 2019, the 2018 Investor Note of one investor was paid in full. On March 19, 2020, the Company and the L2 Capital, LLC (“L2”) agreed to extend the note maturity to June 28, 2020. The Company and L2 further agreed to extend the due date to July 15, 2020 and then in July 2020 agreed to extend to September 30, 2020. Effective September 30, 2020, L2 and the Company agreed to extend to March 31, 2021.

Each investor received the right to convert all or any part of its portion of the 2018 Investor Note into shares of the Company’s common stock at a discounted price, subject to certain limitations. During the year ended December 31, 2020, L2 converted $267,328 of the principal balance, and received 170,000 shares of the Company’s common stock.

During September 2019, the Company issued a secured promissory note with a principal amount of $847,500 (the “2019 Investor Note”) to Oasis Capital, LLC (“Oasis”), an affiliate of L2, in exchange for cash proceeds of $700,000. As additional consideration for the loan, the Company issued an aggregate 8,857 shares of its common stock to Oasis plus warrants to acquire up to 68,237 shares of the Company’s common stock at an exercise price of $6.21 per share. The warrants are exercisable beginning on the sixth month anniversary of the effective date through the fifth-year anniversary thereof. The 2019 Investor Note accrued interest at a rate of 8% per annum. On March 19, 2020, the Company entered into an agreement to extend the due date the 2019 Investor Note from March 2020 to June 27, 2020. The Company increased the principal amount due on the 2019 Investor Note by $300,000 and issued 30,000 shares of its common stock as consideration for the extension. The change in value resulting from the extension exceeded 10% and as a result the extension was accounted for as an extinguishment under ASC 470, Debt. During the first quarter of 2020, the Company incurred a $300,000 loss on debt extinguishment related to the extension of the note. The Company and Oasis further agreed to extend the due date of the note to July 15, 2020 and then agreed to extend to September 30, 2020. The change in value resulting from the extension to September 30, 2020 exceeded 10% and as a result the extension was accounted for as an extinguishment under ASC 470, Debt. During the third quarter of 2020, the Company incurred a $345,000 loss on debt extinguishment related to the extension of the 2019 Investor Note to September 30, 2020. Effective September 30, 2020, Oasis and the Company agreed to further extend the maturity date of the 2019 Investor Note to March 31,2021. The change in value resulting from the extension to March 31, 2021 exceeded 10% and as a result the extension was accounted for as an extinguishment under ASC 470, Debt. During the third quarter of 2020, the Company incurred a $690,000 loss on debt extinguishment related to the extension of the note to March 31, 2021. Further, the parties agreed that the note shall be convertible into shares of the Company’s common stock, at a conversion price equal to the lesser of (i) $1.00 and (ii) 70% of the lowest VWAP (as defined in the note) of the Company’s common stock during the twenty (20) Trading Day (as defined) period ending on either (i) the last complete Trading Day prior to the conversion date or (ii) the conversion date, as determined by the holder in its sole discretion upon such conversion (subject to adjustment). During the fourth quarter of 2020, Oasis converted $525,000 in outstanding principal of the 2019 Investor Note in exchange for 1,136,448 shares of the Company’s common stock. No payment penalties were paid in relation to payments on this promissory note during the year ended December 31, 2020 and $320,542 in payment penalties were accrued but not paid as of December 31, 2020. As of December 31, 2020, the remaining balance on the promissory note was $1,490,833 with $244,830 unamortized discount.

On February 5, 2020, the Company issued a secured promissory note with a principal amount of $1,450,000 (the “2020 Investor Note”) to Oasis. Net proceeds of $400,000 were received for each of the first, second, and third tranches on February 5, 2020, March 5, 2020, and April 5, 2020, respectively. The Company granted to Oasis a security interest in its assets to secure repayment of the note. The 2020 Investor Note accrued interest at a rate of 8% per annum. Subject to certain limitations, the outstanding principal amount of the note and interest thereon were convertible at the election of the investor into shares of the Company’s common stock at a conversion price equal to $2.589. The conversion price was amended effective September 30, 2020 to a variable price equal to 70% of the lowest VWAP (as defined in the note) of Company’s common stock during the twenty (20) Trading Day (as defined in the note) period ending on either (i) the last complete Trading Day prior to the conversion date or (ii) the conversion date, as determined by the holder in its sole discretion upon such conversion (subject to adjustment). The note contains a conversion feature and a put which were determined to be derivatives and are discussed further below. Effective July 15, 2020, the Company and Oasis agreed to amend the maturity date of the note to September 30, 2020. The change in value resulting from the amendment to maturity to September 30, 2020 exceeded 10% and as a result the amendment was accounted for as an extinguishment under ASC 470, Debt. During the third quarter of 2020, the Company incurred a $172,500 loss on debt extinguishment related to the amendment of the note to September 30, 2020. Effective September 30, 2020, the investor and the Company agreed to further extend the maturity date of the 2020 Investor Note to March 31, 2021. The change in value resulting from the extension to March 31, 2021 exceeded 10% and as a result the extension was accounted for as an extinguishment under ASC 470, Debt.

The Company also issued 46,875 shares of its common stock to Oasis at the closing of the first tranche. During the fourth quarter of 2020, Oasis converted $503,354 in outstanding principal in exchange for 1,075,911 shares of the Company’s common stock.

As of December 31, 2020, the outstanding balance on the promissory note was $1,464,146 with no remaining unamortized discount.

Dr. Schwartz Notes

In November 2018, Dr. Schwartz made a loan to the Company with a principal balance of $370,000. As of December 31, 2018, one promissory note was held with a principal balance of $370,000 and an unamortized discount of $63,028. From November 30, 2018 through July 15, 2019, Dr. Schwartz made numerous loans to the Company in the total amount of $1,920,000 under two promissory notes. As consideration for these amounts, Dr. Schwartz received promissory notes and warrants to purchase 22,129 shares of the Company’s common stock at $8.36 per share. Further, beginning on February 1, 2019 and the first day of each calendar month thereafter while the note remained outstanding, a number of additional warrants were issued. Beginning in October 2019, the Company and Dr Schwartz began to renegotiate the note. Due to the negotiations, the Company did not issue any additional warrants because they would be cancelled under the new deal.

During January 2020, the Company entered into an exchange agreement with Dr. Schwartz. Under the exchange agreement, the two outstanding notes were cancelled and in exchange a new promissory note in the amount of $2,115,000 bearing 12% interest per annum and maturing on September 30, 2020 was issued. In addition to the promissory note, Dr. Schwartz received 50,000 shares of the Company’s common stock. All warrants issued under the prior promissory notes were cancelled under the exchange agreement; no rights and obligations remain under the cancelled notes. The Company determined that the exchange agreement had, in substance, occurred at December 31, 2019.

Effective as of April 21, 2020, the Company and Carl Schwartz, entered into an exchange agreement relating to a promissory note of the Company dated January 31, 2020 issued by the Company in the principal amount of $2,115,000. The note bore twelve percent (12%) interest per annum and had a maturity date of September 30, 2020. The accrued interest on the note through April 21, 2020 was $77,878, resulting in a total balance of $2,192,878 in principal and accrued interest on the Note as of such date. Dr. Schwartz and the Company agreed to exchange the note for newly issued shares of common stock of the Company at market value. Pursuant to the exchange agreement, Dr. Schwartz was issued 1,583,481 shares of newly issued common stock at an exchange rate of $1.43 per share, equal to the closing price of the common stock on April 21, 2020. Dr. Schwartz agreed (1) not to sell or otherwise transfer 766,740 shares for three months after the date of the exchange agreement, and (2) not to sell or otherwise transfer the remaining 766,741 shares for six months after the date of the exchange agreement. In 2021, the Company determined that due to a calculation error, the balance of the 2020 Schwartz Note should have been higher by $143,573 at the time of the exchange agreement, and on February 24, 2021, the Company issued an additional 100,401 shares to Dr. Schwartz.

Short Term Borrowings

The Company entered into short-term borrowings with an investor. The maturity date of the notes is six months after the dates of issuance with interest rates of 8% payable at maturity.

Payment penalties of $247,327 were paid in relation to payments on these short-term borrowings during the year ended December 31, 2020. There were no amounts outstanding under the short-term borrowings as of December 31, 2020.

April 2020 Paycheck Protection Program

On April 20, 2020, the Company entered into a promissory note with Park State Bank, which provides for an unsecured loan of $541,867 pursuant to the Paycheck Protection Program (the “PPP”) under the Coronavirus Aid, Relief, and Economic Security Act and applicable regulations (the “CARES Act”). The promissory note has a term of 2 years with a 1% per annum interest rate. Payments are deferred for 6 months from the date of the promissory note and the Company can apply for forgiveness of all or a portion of the promissory note after 60 days for covered use of funds.

Pursuant to the terms of the PPP, the promissory note, or a portion thereof, may be forgiven if proceeds are used for qualifying expenses as described in the CARES Act, such as payroll costs, costs used to continue group health care benefits, mortgage interest payments, rent and utilities. The Company has used all proceeds for qualifying expenses. The Company received forgiveness for the loan under the Paycheck Protection Program and recognized a gain in other income for the full amount of the loan during the fourth quarter of 2020.

Notes to Financial Statements

Derivative Instruments and Hedging Activities Disclosure [Text Block]

NOTE 7 - DERIVATIVES

The Company concluded the September 2018 Investor Note contained a conversion feature which is an embedded derivative and required bifurcation. The embedded derivative’s value was determined using the discounted stock price for the 20-trading days preceding the balance sheet date and the assumption of conversion on that date, as management believed it was probable that the notes would be convertible based on management’s expectation that additional financing would be required. During the year ended December 31, 2020, the maximum number of conversions was reached. The Company recognized an unrealized gain for the corresponding change in fair value of $50,989 for the year ended December 31, 2020. The fair value of the derivative liability related to the bridge loan was zero as of December 31, 2020.

The Company concluded the Promissory Note 2020 contained a conversion feature and a put each of which was an embedded derivative and are required to be bifurcated. In accordance with ASC 815, Derivatives and Hedging, the Company combined these two embedded derivatives into a single derivative and determined the fair value to record within the derivative liability on the consolidated balance sheet. At inception, the fair value of the derivative liability was $68,796, $52,125 and $20,542 for the first, second and third tranches, respectively. During the year ended December 31, 2020, the Company recognized a gain of $87,923 on the change in the fair value of the derivative liability. As a result of the repayment of the note as of March 1, 2021, the embedded derivative had a fair value of zero prior to the repayment. The Company recorded a gain on the fair value of the derivative of $104,529 during the year ended December 31, 2021. As of December 31, 2020, the fair value of the derivative liability was $104,529.

The Company concluded the A, B and agent warrants issued in connection with the March 2020 Private Placement discussed above are a derivative liability due to certain features of the warrants which could, in certain circumstances, result in the holder receiving the Black Scholes value of the outstanding warrants in the same type of consideration as the common stockholders. As a result, in those circumstances, the amount of consideration would differ from that provided to holders of common stock, therefore, the warrants were classified as a liability. At inception, the A, B and agent warrants had a fair value of $2,669,995. During the third quarter of 2020, the A and B warrants were amended as discussed in Note 6 - Notes Payable above. As a result of this amendment, the warrants no longer represented a liability to the Company and were reclassified to equity. Prior to reclassification, a gain on the change in fair value of $700,910 was recorded during the year ended December 31, 2020. As of December 31, 2021, the fair value of the agent warrants was determined to be $41,336 and the Company recorded a loss on the change in fair value of $7,683 during the year ended December 31, 2021.

The Company concluded the warrants and agent warrants issued in connection with the May 2020 Offering discussed above are a derivative liability due to certain features of the warrants which could, in certain circumstances, result in the holder receiving the Black Scholes value of the outstanding warrants in the same type of consideration as the common stockholders. As a result, in those circumstances, the amount of consideration would differ from that provided to holders of common stock, therefore, the warrants were classified as a liability. At inception, the warrants and agent warrants had a fair value of $1,324,184. The Company recorded a loss on the change in fair value of the warrants of $460,065 during the year ended December 31, 2020. During June 2020, the investors exercised the warrants and exchanged the warrants for shares of common stock as discussed above. The fair value of the agent warrants was determined to be $33,819 and $42,646 as of December 31, 2021 and as of December 31, 2020, respectively. The Company recorded a loss on the change in fair value of the agent warrants of $8,827 during the year ended December 31, 2021 and a gain on the change in fair value of the agent warrants of $48,675 during the year ended December 31, 2020.

In connection with the June 2020 Warrant exercise and issuance, the Company concluded the warrants and agent warrants issued in connection with the June 2020 Warrant exercise and issuance, discussed above, are a derivative liability due to certain features of the warrants which could, in certain circumstances, result in the holder receiving the Black Scholes value of the outstanding warrants in the same type of consideration as the common stockholders. As a result, in those circumstances, the amount of consideration would differ from that provided to holders of common stock, therefore, the warrants were classified as a liability. At inception, the warrants and agent warrants had a fair value of $1,749,721. During the year ended December 31, 2020, the June warrants were amended. As a result of this amendment, the warrants no longer represented a liability to the Company and were reclassified to equity. Prior to reclassification, the Company recorded a gain on the change in fair value of the warrants of $834,520 during the year ended December 31, 2020. The Company recorded a loss on the change in fair value of the agent warrants of $12,797 during the year ended December 31, 2021 and a gain on the change in fair value of the agent warrants of $79,045 during the year ended December 31, 2020. The fair value of the agent warrants was $45,498 and $32,701 as of December 31, 2021 and as of December 31, 2020, respectively.

On September 30, 2020, the Promissory Note 2019 was amended. The Company concluded the Promissory Note 2019 contained a conversion feature which is an embedded derivative and is required to be bifurcated. In accordance with ASC 815, Derivatives and Hedging, the Company determined the fair value to record within the derivative liability on the consolidated balance sheet. At inception, the fair value of the derivative liability was $495,100. As a result of the repayment of the note as of March 1, 2021, the embedded derivative had a fair value of zero prior to the repayment. The Company recorded a gain on the fair value of the derivative of $89,680 during the year ended December 31, 2021. The Company recorded a gain on the change in fair value of the derivative liability of $405,420 during the year ended December 31, 2020. As of December 31, 2020, the fair value of the derivative liability was $89,680.

NOTE 9 – INCOME TAXES

The provision for income taxes consists of an amount for taxes currently payable and a provision for tax consequences deferred to future periods. Deferred income taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income 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 Company recognized an income tax benefit of $661,658 in our consolidated statement of net loss related to the release of valuation allowance as a result of the zPREDICTA business combination. However, due to the cumulative operating losses, the Company determined that a 100% valuation allowance for the net deferred tax assets at December 31st is appropriate.

Actual income tax benefit differs from statutory federal income tax benefit as follows:

The Company has determined, based upon its history, that it is probable that future taxable income may be insufficient to fully realize the benefits of the net operating loss (“NOL”) carryforwards and other deferred tax assets. As such, the Company has determined that a full valuation allowance is warranted. Future events and changes in circumstances could cause this valuation allowance to change.

The acquired NOL carryforwards from zPREDICTA experienced an ownership change as defined in Section 382 of the Internal Revenue Code as a result of the merger. In addition, the Company experienced an ownership change in 2019 with the Helomics acquisition as well as December 2013. As a result, the ability to utilize the Company’s NOLs is limited. The Company may have experienced additional ownership changes since December 2013, but a formal study has not yet been performed. The general limitation rules allow the Company to utilize its NOLs subject to an annual limitation that is determined by multiplying the federal long-term tax-exempt rate by the Company’s value immediately before the ownership change.

At December 31, 2020, the Company had $297,735,754 of gross NOLs to reduce future federal taxable income, the majority of which are expected to be available for use in 2021, subject to the Section 382 limitation described above. The federal NOL’s of $261,455,216 expire beginning in 2022 if unused and $36,280,538 will carryforward indefinitely. The Company also had $222,290,524 of gross NOLs to reduce future state taxable income at December 31, 2020. The state NOL’s will expire beginning in 2021 if unused. The Company dissolved its Belgium subsidiary in 2020 and all carryforward tax losses will be eliminated on the final 2020 Belgium tax return filed. The Company's net deferred tax assets, which include the NOLs, are subject to a full valuation allowance. At December 31, 2020, the federal, state, and foreign valuation allowances were $59,913,739, $22,191,346, and $0, respectively.

At December 31, 2021, the Company had $308,990,822 of gross NOLs to reduce future federal taxable income, the majority of which are expected to be available for use in 2022, subject to the Section 382 limitation described above. The federal NOL’s of $259,490,005 expire beginning in 2023 if unused and $49,500,817 will carryforward indefinitely. The Company also had $227,277,399 of gross NOLs to reduce future state taxable income at December 31, 2021. The state NOL’s will expire beginning in 2022 if unused. The Company's net deferred tax assets, which include the NOLs, are subject to a full valuation allowance. At December 31, 2021, the federal and state valuation allowances were $62,034,750 and $23,145,374 respectively.

Tax years subsequent to 2001 remain open to examination by federal and state tax authorities due to unexpired net operating loss carryforwards.

The Company reviews income tax positions expected to be taken in income tax returns to determine if there are any income tax uncertainties. The Company recognizes tax benefits from uncertain tax positions only if it is more likely than not that the tax positions will be sustained on examination by taxing authorities, based on technical merits of the positions. The Company has identified no income tax uncertainties.

The Company recognizes interest and penalties on unrecognized tax benefits as well as interest received from favorable tax settlements within income tax expense. At December 31, 2021 and 2020, the Company recorded no accrued interest or penalties related to uncertain tax positions.

NOTE 10 – Goodwill and Intangibles

Intangible Assets

Finite-lived intangible assets consist of patents and trademarks, licensing fees, developed technology, acquired software and customer relationships, and are amortized over their estimated useful life. Amortization expense was $374,328 and $313,709 in 2021 and 2020, respectively. Accumulated amortization is included in intangibles, net in the accompanying consolidated balance sheets. The Company reviews finite-lived identifiable intangible assets for impairment in accordance with ASC 360, Property, Plant and Equipment, whenever events or changes in circumstances indicate the carrying amount may not be recoverable. Events or changes in circumstances that indicate the carrying amount may not be recoverable include, but are not limited to, a significant change in the medical device marketplace and a significant adverse change in the business climate in which the Company operates.

As of December 31, 2021, there were $3,962,118 in net intangibles as compared to $3,398,101 in net intangibles as of December 31, 2020.

The components of intangible assets were as follows:

Impairment of Long-Lived Assets

The Company reviews long-lived assets, including property and equipment and intangible assets with estimable useful lives, for impairment whenever events or changes in circumstances indicate that the carrying amount of such an asset may not be recoverable.

The recoverability of an asset to be held and used is determined by comparing the carrying amount to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of the asset exceeded its estimated undiscounted future cash flows, the Company recorded an impairment charge in the amount by which the carrying amount of the asset exceeds its fair value, which is determined by either a quoted market price, if any, or a value determined by utilizing discounted cash flow techniques.

The Company prepared an undiscounted cash flow as of December 31, 2021 to evaluate long-lived assets based on a triggering event per ASC 360. The Company concluded that the undiscounted cash flows did not support the carrying values of its Helomics asset group at December 31, 2021. The Company determined the value of the intangibles and the software license acquired were fully impaired as of December 31, 2021 and recognized and impairment loss of $2,893,548 for its long-lived intangible assets and $1,249,727 for the acquired software. The Company concluded there was no impairment of its other finite lived tangible assets as of December 31, 2021. No impairment charges were incurred during 2020.

Goodwill

In accordance with ASC 350, Intangibles – Goodwill and Other, goodwill is calculated as the difference between the acquisition date fair value of the consideration transferred and the fair value of net assets acquired. Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination. Goodwill is an indefinite-lived asset and is not amortized. Goodwill is tested for impairment annually at the reporting unit level, or whenever events or circumstances present an indication of impairment.

In the Helomics acquisition, the Company recorded goodwill of $23,790,290. The goodwill was recorded to the Helomics segment which represents a single reporting unit. As a part of the annual impairment testing as of December 31, 2019, the Company had the option to assess qualitative factors to determine if it was more likely than not that the carrying value of a reporting unit exceeded its estimated fair value. The Company believed a qualitative testing approach was not appropriate and, therefore, proceeded to the quantitative testing. When performing quantitative testing, the Company first estimated the fair value of the Helomics reporting unit using discounted cash flows. To determine fair values, the Company was required to make assumptions about a wide variety of internal and external factors. Significant assumptions used in the impairment analysis included financial projections of free cash flow (including significant assumptions about operations including the rate of future revenue growth, capital requirements, and income taxes), long-term growth rates for determining terminal value, and discount rates for the Helomics reporting unit. Comparative market multiples were also used to corroborate the results of the discounted cash flow test. These assumptions required significant judgment and actual results may differ from assumed and estimated amounts.

In testing goodwill for impairment as of September 30, 2020, the Company performed a quantitative impairment test, including computing the fair value of the Helomics reporting unit and comparing that value to its carrying value. Based upon the Company’s quantitative goodwill impairment test, the Company concluded that goodwill was impaired as of the testing date of September 30, 2020. Pursuant to ASU 2017-04, Simplifying the Test for Goodwill Impairment, the single step is to determine the estimated fair value of the reporting unit and compare it to the carrying value of the reporting unit, including goodwill. To the extent the carrying amount of goodwill exceeds the implied goodwill, the difference is the amount of the goodwill impairment. The quantitative review as of September 30, 2020 resulted in $2,997,000 of impairment expense related to goodwill.

When evaluating the fair value of Helomics reporting unit the Company used a discounted cash flow model and market comparisons. Key assumptions used to determine the estimated fair value included: (a) expected cash flow for the 20-year period following the testing date (including net revenues, costs of revenues, and operating expenses as well as estimated working capital needs and capital expenditures); (b) an estimated terminal value using a terminal year growth rate of 3.0% determined based on the growth prospects of the reporting unit; and (c) a discount rate of 25% based on management’s best estimate of the after-tax weighted average cost of capital. The discount rate included a Company specific risk premium of 10% for risks related to the term of the forecasts.

In testing goodwill for impairment as of December 31, 2020, the Company performed a quantitative impairment test, including computing the fair value of the Helomics reporting unit and comparing that value to its carrying value. Based upon the Company’s annual goodwill impairment test, the Company concluded that goodwill was impaired as of the testing date of December 31, 2020. The Company’s annual impairment test as of December 31, 2020 resulted in $9,879,498 of impairment expense related to goodwill.  A decrease in the growth rate of 0.5% or an increase of 0.5% to the discount rate would reduce the fair value of Helomics reporting unit by approximately an additional $588,000 and $988,000, respectively.  As of December 31, 2020, the cumulative impairment recorded was $20,976,498.

When evaluating the fair value of Helomics reporting unit the Company used a discounted cash flow model. Key assumptions used to determine the estimated fair value in 2020 included: (a) expected cash flow for the 10-year period following the testing date (including net revenues, costs of revenues, and operating expenses as well as estimated working capital needs and capital expenditures); (b) an estimated terminal value using a terminal year growth rate of 5.0% determined based on the growth prospects of the reporting unit; and (c) a discount rate of 14.0% based on management’s best estimate of the after-tax weighted average cost of capital. The discount rate included a Company specific risk premium of 1.0% for risks related to the term of the forecasts. The Company further used a probability weighting of various forecasts to address forecast risk.

During the third quarter of 2021, the Company concluded that potential impairment indicators were present and that an impairment assessment was warranted for goodwill. In testing goodwill for impairment as of September 30, 2021, the Company performed a quantitative impairment test, including computing the fair value of the Helomics reporting unit and comparing that value to its carrying value. Based upon the Company’s quantitative goodwill impairment test, the Company concluded that goodwill was fully impaired as of September 30, 2021.

The quantitative review as of September 30, 2021 resulted in $2,813,792 of impairment expense related to goodwill. As of September 30, 2021, the cumulative impairment recorded was $23,790,290.

When evaluating the fair value of Helomics reporting unit the Company used a discounted cash flow model and market comparisons. Key assumptions used to determine the estimated fair value included: (a) expected cash flow for the 10-year period following the testing date (including net revenues, costs of revenues, and operating expenses as well as estimated working capital needs and capital expenditures); (b) an estimated terminal value using a terminal year growth rate of 4.0% determined based on the growth prospects of the reporting unit; and (c) a discount rate of 15% based on management’s best estimate of the after-tax weighted average cost of capital. The Company further used a probability weighting of various forecasts to address forecast risk.

Goodwill of $6,857,790 was recognized in the zPREDICTA acquisition and represents the excess of the consideration transferred over the fair values of assets acquired and liabilities assumed and represents the future economic benefits and synergies arising from the transaction. None of the goodwill will be deductible for income tax purposes. See Note 2 – zPREDICTA acquisition.

The following tables present changes in the carrying value of goodwill our consolidated balance sheet:

Goodwill balance at December 31, 2019	$	15,690,290
Impairment		(12,876,498	)
Goodwill balance at December 31, 2020	$	2,813,792
Impairment		(2,813,792	)
Acquisition of zPREDICTA		6,857,790
Goodwill balance at December 31, 2021	$	6,857,790

The majority of the inputs used in the discounted cash flow model are unobservable and thus are considered to be Level 3 inputs. The inputs for the market capitalization calculation are considered Level 1 inputs. The Company will continue to monitor its reporting units to determine whether events and circumstances warrant further interim impairment testing.

NOTE 13 – SEGMENTS

The Company has determined its reportable segments in accordance with ASC 280, Segment Reporting. Factors used to determine the Company’s reportable segments include the availability of separate financial statements, the existence of locally based leadership across geographic regions, the economic factors affecting each segment, and the evaluation of operating results at the segment level. The Chief Operating Decision Maker (“CODM”) allocates the Company’s resources for each of the reportable segments and evaluates their relative performance. Each reportable segment listed below has separate financial statements and locally based leadership that are evaluated based on the results of their respective segments. It should be noted that the reportable segments below have different products and services. The financial information is consolidated and evaluated regularly by the CODM in assessing performance and allocating resources.

During the third quarter of 2020, the Company considered, whether under ASC 280-10-50-3, there was a change in its reportable segments. As a result of the formation of the new Soluble subsidiary, the Company believes the Soluble business represents a reportable segment. Soluble signed its first contract during the third quarter of 2020. The Company also believes it is appropriate to combine our Skyline Medical and Skyline Europe entities into a single reportable segment based on the changes to our physical presence and intent to sign future contracts through the US entity. Finally, the Company believes the Helomics business continues to be a reportable segment.

The Company has four reportable segments: Helomics, zPREDICTA, Soluble and Skyline. See discussion of revenue recognition in Note 1 – Summary of Significant Accounting Policies for a description of the products and services recognized in each segment. The reported financial information below has been reclassified to conform to the current presentation. This information is intended to assist investors in making comparisons of the Company’s historical financial information with future financial information.

Accounting Policies [Abstract]

Basis of Accounting, Policy [Policy Text Block]

Nature of Operations and Continuance of Operations

Predictive Oncology Inc., (the “Company” or “Predictive” or “we”) filed with the Secretary of State of Delaware a Certificate of Amendment to its Certificate of Incorporation to change the corporate name to Predictive Oncology Inc. on June 10, 2019, trading under the new ticker symbol “POAI,” effective June 13, 2019.

The Company operates in four primary business areas: first, application of artificial intelligence (“AI”) in our precision medicine business, to provide AI-driven predictive models of tumor drug response to improve clinical outcomes for patients and to assist pharmaceutical, diagnostic, and biotech industries in the development of new personalized drugs and diagnostics primarily through its wholly owned subsidiary Helomics Holding Corporation (“Helomics”); second, tumor-specific in vitro models for oncology drug discovery and research through its newly acquired wholly-owned subsidiary, zPREDICTA; third, contract services and research focused on solubility improvements, stability studies, and protein production, primarily with our Soluble Biotech subsidiary, and; fourth, production of the United States Food and Drug Administration (“FDA”)-cleared STREAMWAY System for automated, direct-to-drain medical fluid waste disposal and associated products through its incorporated division Skyline.

The Company had cash and cash equivalents of $28,202,615 as of December 31, 2021. As of December 31, 2021, there was no outstanding debt. The Company believes that its existing capital resources will be sufficient to support its operating plan for the next twelve months and beyond. However, the Company may also seek to raise additional capital to support its growth through additional debt, equity or other alternatives or a combination thereof. The Company currently expects to use cash on hand to fund capital and equipment investments, research and development, potential acquisitions and its operations, and expects such sources to be sufficient to fund its requirements over that time.

Effect of Covid-19 Pandemic [Policy Text Block]

Coronavirus Outbreak

The current COVID-19 worldwide pandemic has presented substantial public health challenges. In response to the crisis, emergency measures have been imposed by governments worldwide, including mandatory social distancing and the shutdown of non-essential businesses. These measures have adversely impacted the global economy, disrupted global supply chains and created significant volatility and disruption of financial markets, and our business and operations have been and will likely continue to be materially and adversely affected. For example, our contract manufacturer for the STREAMWAY® System has been forced to change locations, thereby delaying our order fulfillment for parts. We have also reduced on-site staff at several of our facilities, resulting in delayed production, less efficiency, and our sales staff is unable to visit with hospital administrators who are our customers and potential customers. In addition, COVID-19 has impacted the Company’s capital and financial resources, including our overall liquidity position and outlook. For instance, our accounts receivable has slowed while our suppliers continue to ask for pre-delivery deposits. Ultimately, the extent of the impact of the COVID-19 pandemic on our future operational and financial performance will depend on, among other matters, the duration and intensity of the pandemic; the level of success of global vaccination efforts; governmental and private sector responses to the pandemic and the impact of such responses on us; and the impact of the pandemic on our employees, customers, suppliers, operations and sales, all of which are uncertain and cannot be predicted. These factors may remain prevalent for a significant period of time even after the pandemic subsides, including due to a continued or prolonged recession in the U.S. or other major economies. Even in areas where "stay-at-home" restrictions, masking and social distancing measures have been lifted and the number of COVID-19 cases have declined, some jurisdictions may re-impose these measures as and if variant strains emerge or cases rise. The impacts of the COVID-19 pandemic, as with any adverse public health developments, could have a material adverse effect on our business, results of operations, liquidity or financial condition and heighten or exacerbate risks described in this Annual Report on Form 10-K.

New Accounting Pronouncements, Policy [Policy Text Block]

Recently Adopted Accounting Standards

The Company considers the applicability and impact of all Accounting Standards Updates (“ASUs”) issued by the Financial Accounting Standards Board (the “FASB”). Recently issued ASUs not listed below either were assessed and determined to be not applicable or are currently expected to have no impact on the condensed consolidated financial statements of the Company.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses.” This ASU added a new impairment model (known as the current expected credit loss (“CECL”) model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses. The CECL model applies to most debt instruments, trade receivables, lease receivables, financial guarantee contracts, and other loan commitments. The CECL model does not have a minimum threshold for recognition of impairment losses and entities will need to measure expected credit losses on assets that have a low risk of loss. As a smaller reporting company pursuant to Rule 12b-2 of the Securities Exchange Act of 1934, as amended, these changes become effective for the Company on January 1, 2023. Management is currently evaluating the potential impact of these changes on the consolidated financial statements of the Company.

Use of Estimates, Policy [Policy Text Block]

Accounting Policies and Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and disclosure of contingent assets and liabilities at the date of the financial statements and during the reporting period. Actual results could materially differ from those estimates.

Reclassification, Comparability Adjustment [Policy Text Block]

Reclassifications

Certain reclassifications have been made to the prior years’ financial statements to conform to the current year presentation. The reclassifications had no effect on previously reported results of operations, cash flows or stockholders’ equity.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and cash equivalents

The Company considers all highly liquid instruments with maturities when purchased of three months or less to be cash equivalents. The Company places its cash with high quality financial institutions and believes its risk of loss is limited to amounts in excess of that which is insured by the Federal Deposit Insurance Corporation.

Receivable [Policy Text Block]

Receivables

Receivables are reported at the amount the Company expects to collect on balances outstanding. The Company provides for probable uncollectible amounts through charges to earnings and credits to the valuation allowance based on management’s assessment of the current status of individual accounts.

Amounts recorded in accounts receivable on the consolidated balance sheet include amounts billed and currently due from customers. The amounts due are stated at their net estimated realizable value. An allowance for doubtful accounts is maintained to provide for the estimated amount of receivables that will not be collected. The Company reviews customers’ credit history before extending unsecured credit and establishes an allowance for uncollectible accounts based upon factors surrounding the credit risk of specific customers, historical trends and other information. Invoices are generally due 30 days after presentation. Accounts receivable over 30 days is generally considered past due. The Company does not accrue interest on past due accounts receivables. Receivables are written off once all collection attempts have failed and are based on individual credit evaluation and specific circumstances of the customer. The allowance for doubtful accounts balance was $0 as of both December 31, 2021 and 2020.

Fair Value Measurement, Policy [Policy Text Block]

Fair Value Measurements

As outlined in Accounting Standards Codification (“ASC”) 820, Fair Value Measurement, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The accounting standards ASC 820 establishes a three-level fair value hierarchy that prioritizes information used in developing assumptions when pricing an asset or liability as follows:

Level 1 – Observable inputs such as quoted prices in active markets;

Level 2 – Inputs other than quoted prices in active markets, that are observable either directly or indirectly; and

Level 3 – Unobservable inputs where there is little or no market data, which requires the reporting entity to develop its own assumptions.

The Company uses observable market data, when available, in making fair value measurements. Fair value measurements are classified according to the lowest level input that is significant to the valuation.

The fair value of the Company’s investment securities, which consist of cash and cash equivalents, was determined based on Level 1 inputs. The fair value of the Company’s derivative liabilities and debt were determined based on Level 3 inputs. The Company generally uses Black Scholes method for determining the fair value of warrants classified as liabilities on a recurring basis. In addition, the Company uses the Monte Carlo method and other acceptable valuation methodologies when valuing the conversion feature and other embedded features classified as derivatives on a recurring basis. See Note 7 – Derivatives. When performing quantitative testing related to goodwill impairment analysis, the Company estimates the fair values of its reporting units using discounted cash flows. To determine fair values, the Company is required to make assumptions about a wide variety of internal and external factors. Significant assumptions used in the impairment analysis include financial projections of free cash flow (including significant assumptions about operations including the rate of future revenue growth, capital requirements, and income taxes), long-term growth rates for determining terminal value and discount rates. The majority of the inputs used in the discounted cash flow model are unobservable and thus are considered to be Level 3 inputs. See Note 10 – Goodwill and Intangibles.

The acquisition of zPREDICTA was accounted for as a business combination using the acquisition method of accounting. This method requires, among other things, that assets acquired and liabilities assumed be recognized at fair value as of the acquisition date. The fair value for the assets acquired and the liabilities assumed are based on information knowable and determined by management as of the acquisition date. The majority of the inputs used in the discounted cash flow model, the relief-from-royalty method under the income approach, the distributor method under the income approach and the multi-period excess earnings method under the income approach, each are unobservable and thus are considered to be Level 3 inputs. See Note 2 – zPREDICTA Acquisition.

Inventory, Policy [Policy Text Block]

Inventories

Inventories are stated at the lower of cost or net realizable value, with cost determined on a first-in, first-out basis.  

Property, Plant and Equipment, Policy [Policy Text Block]

Fixed Assets

Fixed assets are stated at cost less accumulated depreciation. Depreciation of fixed assets is computed using the straight-line method over the estimated useful lives of the respective assets. Estimated useful asset life by classification is as follows: 

	Years
Computers, software and office equipment	3	-	10
Leasehold improvements (1)	2	-	5
Manufacturing tooling	3	-	7
Laboratory equipment	4	-	10
Demo equipment		3

(1) Leasehold improvements are amortized over the shorter of the useful life or the remaining lease term.

Upon retirement or sale of fixed assets, the cost and related accumulated depreciation or amortization are removed from the balance sheet and the resulting gain or loss is reflected in operations. Maintenance and repairs are charged to operations expense as incurred.

Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block]

Long-lived Assets

Finite-lived intangible assets consist of patents and trademarks, licensing fees, developed technology, acquired software and customer relationships, and are amortized over their estimated useful life. Accumulated amortization is included in intangibles, net in the accompanying consolidated balance sheets.

The Company reviews finite-lived identifiable intangible assets for impairment in accordance with ASC 360, Property, Plant and Equipment, whenever events or changes in circumstances indicate the carrying amount may not be recoverable. Events or changes in circumstances that indicate the carrying amount may not be recoverable include, but are not limited to, a significant change in the medical device marketplace and a significant adverse change in the business climate in which the Company operates.

The Company prepared an undiscounted cash flow as of December 31, 2021 to evaluate long-lived assets based on a triggering event per ASC 360. The Company concluded that the undiscounted cash flows did not support the carrying values of its Helomics asset group at December 31, 2021. The Company determined the value of the intangibles and the software license acquired were fully impaired as of December 31, 2021 and recognized and impairment loss of $2,893,548 for its long-lived intangible assets and $1,249,727 for the acquired software. The Company concluded there was no impairment of its other finite lived tangible assets as of December 31, 2021. See Note 10 – Intangible Assets and Goodwill.

The Company also prepared an undiscounted cash flow as of December 31, 2020 to evaluate long-lived assets based on a triggering event at that time. The Company concluded that the undiscounted cash flows of the long-lived assets exceeded the carrying values. The Company concluded there was no impairment of its finite lived assets as of December 31, 2020.

Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]

Goodwill

In accordance with ASC 350, Intangibles – Goodwill and Other, goodwill is calculated as the difference between the acquisition date fair value of the consideration transferred and the fair value of net assets acquired. Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination. Goodwill is not amortized but is tested on an annual basis for impairment at the reporting unit level as of December 31, or whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable.

To determine whether goodwill is impaired, annually or more frequently if needed, the Company performs a multi-step impairment test. The Company first has the option to assess qualitative factors to determine if it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value. The Company may also elect to skip the qualitative testing and proceed directly to the quantitative testing. When performing quantitative testing, the Company first estimates the fair values of its reporting units using discounted cash flows. To determine fair values, the Company is required to make assumptions about a wide variety of internal and external factors. Significant assumptions used in the impairment analysis include financial projections of free cash flow (including significant assumptions about operations including the rate of future revenue growth, capital requirements, and income taxes), long-term growth rates for determining terminal value and discount rates. Comparative market multiples are used to corroborate the results of the discounted cash flow test. These assumptions require significant judgement. Pursuant to ASU 2017-04, Simplifying the Test for Goodwill Impairment, the single step is to determine the estimated fair value of the reporting unit and compare it to the carrying value of the reporting unit, including goodwill. To the extent the carrying amount of goodwill exceeds the implied goodwill, the difference is the amount of the goodwill impairment. The Company also completes a reconciliation between the implied equity valuation prepared and the Company’s market capitalization. The majority of the inputs used in the discounted cash flow model are unobservable and thus are considered to be Level 3 inputs. The inputs for the market capitalization calculation are considered Level 1 inputs. See Note 3 – Intangible Assets and Goodwill.

Lessee, Leases [Policy Text Block]

Leases – At inception of a contract a determination is made whether an arrangement meets the definition of a lease. A contract contains a lease if there is an identified asset and the Company has the right to control the asset. Operating leases are recorded as right-of-use (“ROU”) assets with corresponding current and noncurrent operating lease liabilities on our consolidated balance sheets. Financing leases are included within fixed assets with corresponding current liability within other current liabilities and noncurrent liability within other long-term liabilities on our consolidated balance sheets.

ROU assets represent our right to use an underlying asset for the duration of the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Recognition on the commencement date is based on the present value of lease payments over the lease term using an incremental borrowing rate. Leases with a term of 12 months or less at the commencement date are not recognized on the balance sheet and are expensed as incurred.

The Company has lease agreements with lease and non-lease components, which are accounted for as a single lease component for all asset classes. Leases are accounted for at a portfolio level when similar in nature with identical or nearly identical provisions and similar effective dates and lease terms.

Revenue from Contract with Customer [Policy Text Block]

Revenue Recognition

The Company recognizes revenue when it satisfies a performance obligation by transferring control of the promised goods or services to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Sales taxes are imposed on the Company’s sales to nonexempt customers. The Company collects the taxes from the customers and remits the entire amounts to the governmental authorities. Sales taxes are excluded from revenue and expenses.

Revenue from Product Sales

The Company has medical device revenue consisting primarily of sales of the STREAMWAY System, as well as sales of the proprietary cleaning fluid and filters for use with the STREAMWAY System. This revenue stream is reported within both the domestic and international revenue segments. The Company sells its medical device products directly to hospitals and other medical facilities using employed sales representatives and independent contractors. Purchase orders, which are governed by sales agreements in all cases, state the final terms for unit price, quantity, shipping and payment terms. The unit price is considered the observable stand-alone selling price for the arrangements. The Company sales agreement, and Terms and Conditions, is a dually executed contract providing explicit criteria supporting the sale of the STREAMWAY System. The Company considers the combination of a purchase order and acceptance of its Terms and Conditions to be a customer’s contract in all cases.

Product sales for medical devices consist of a single performance obligation that the Company satisfies at a point in time. The Company recognizes product revenue when the following events have occurred: (1) the Company has transferred physical possession of the products, (2) the Company has a present right to payment, (3) the customer has legal title to the products, and (4) the customer bears significant risks and rewards of ownership of the products. Based on the shipping terms specified in the sales agreements and purchase orders, these criteria are generally met when the products are shipped from the Company’s facilities (“FOB origin,” which is the Company’s standard shipping terms). As a result, the Company determined that the customer is able to direct the use of, and obtain substantially all of the benefits from, the products at the time the products are shipped. The Company may, at its discretion, negotiate different shipping terms with customers which may affect the timing of revenue recognition. The Company’s standard payment terms for its customers are generally 30 to 60 days after the Company transfers control of the product to its customer. The Company allows returns of defective disposable merchandise if the customer requests a return merchandise authorization from the Company.

Customers may also purchase a maintenance plan for the medical devices from the Company, which requires the Company to service the STREAMWAY System for a period of one year subsequent to the one-year anniversary date of the original STREAMWAY System invoice. The maintenance plan is considered a separate performance obligation from the product sale, is charged separately from the product sale, and is recognized over time (ratably over the one-year period) as maintenance services are provided. A time-elapsed output method is used to measure progress because the Company transfers control evenly by providing a stand-ready service. The Company has determined that this method provides a faithful depiction of the transfer of services to its customers.

All amounts billed to a customer in a sales transaction for medical devices related to shipping and handling, if any, represent revenues earned for the goods provided, and these amounts have been included in revenue. Costs related to such shipping and handling billing are classified as cost of goods sold. This revenue stream is reported under the Skyline reportable segment.

Revenue from Clinical Testing

Clinic diagnostic testing is comprised of our Tumor Drug Response Testing (ChemoFx) and Genomic Profiling (BioSpeciFx) tests. The Tumor Drug Response Testing test determines how a patient’s tumor specimen reacts to a panel of various chemotherapy drugs, while the Genomic Profiling test evaluates the expression and/or status of a particular gene related to a patient’s tumor specimen. Revenues are recognized when control of the promised goods or services is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The estimated uncollectible amounts are generally considered implicit price concessions that are a reduction in revenue. Helomics’ payments terms vary by the agreements reached with insurance carriers and Medicare. The Company’s performance obligations are satisfied at one point in time when test reports are delivered.

For service revenues, the Company estimates the transaction price which is the amount of consideration it expects to be entitled to receive in exchange for providing services based on its historical collection experience using a portfolio approach as a practical expedient to account for patient contracts as collective groups rather than individually. The Company monitors its estimates of transaction price to depict conditions that exist at each reporting date. If the Company subsequently determines that it will collect more consideration than it originally estimated for a contract with a patient, it will account for the change as an increase to the estimate of the transaction price, provided that such downward adjustment does not result in a significant reversal of cumulative revenue recognized.

The Company recognizes revenue from these patients when contracts as defined in ASC 606, Revenue from Contracts with Customers are established at the amount of consideration to which it expects to be entitled or when the Company receives substantially all of the consideration subsequent to the performance obligations being satisfied. The Company’s standard payment term for hospital and patient direct bill is 30 days after invoice date. This revenue stream is reported under the Helomics segment.

CRO Revenue

Contract revenues are generally derived from studies conducted with biopharmaceutical and pharmaceutical companies. The specific methodology for revenue recognition is determined on a case-by-case basis according to the facts and circumstances applicable to a given contract. The Company typically uses an input method that recognizes revenue based on the Company’s efforts to satisfy the performance obligation relative to the total expected inputs to the satisfaction of that performance obligation. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation on the basis of the standalone-selling price of each distinct good or service in the contract. Advance payments received in excess of revenues recognized are classified as deferred revenue until such time as the revenue recognition criteria have been met. Payment terms are net 30 from the invoice date, which is sent to the customer as the Company satisfies the performance obligation relative to the total expected inputs to the satisfaction of that performance obligation. This revenue stream is reported under the Helomics and zPREDICTA segments.

Variable Consideration

The Company records revenue from distributors and direct end customers in an amount that reflects the transaction price it expects to be entitled to after transferring control of those goods or services. The Company’s current contracts do not contain any features that create variability in the amount or timing of revenue to be earned.

Warranty

The Company generally provides one-year warranties against defects in materials and workmanship on product sales and will either repair the products or provide replacements at no charge to customers. As they are considered assurance-type warranties, the Company does not account for them as separate performance obligations. Warranty reserve requirements are based on a specific assessment of the products sold with warranties where a customer asserts a claim for warranty or a product defect. 

Contract Balances

The Company records a receivable when it has an unconditional right to receive consideration after the performance obligations are satisfied. As of December 31, 2021 and 2020, accounts receivable totaled $354,196 and $256,878, respectively.

The Company’s deferred revenues related primarily to our zPREDICTA contract research revenue and maintenance plans of our Skyline Medical operating segment. As of December 31, 2021 and 2020, deferred revenue was $186,951 and $53,028, respectively.

Practical Expedients

The Company has elected the practical expedient not to determine whether contracts with customers contain significant financing components as well as the practical expedient to recognize shipping and handling costs at point of sale.

Valuation and Accounting for Stock Options and Warrants, Policy [Policy Text Block]

Valuation and accounting for stock options and warrants

The Company determines the grant date fair value of options and warrants using a Black-Scholes option valuation model based upon assumptions regarding risk-free interest rate, expected dividend rate, volatility and estimated term.

Costs incurred which are direct and incremental to an offering of the Company’s securities are deferred and charged against the proceeds of the offering, unless such costs are deemed to be insignificant in which case they are expensed as incurred.

Income Tax, Policy [Policy Text Block]

Income Taxes

The Company accounts for income taxes in accordance with ASC 740, Income Taxes (“ASC 740”). Under ASC 740, deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities and net operating loss and credit carryforwards using enacted tax rates in effect for the year in which the differences are expected to impact taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized.

The Company reviews income tax positions expected to be taken in income tax returns to determine if there are any income tax uncertainties. The Company recognizes tax benefits from uncertain tax positions only if it is more likely than not that the tax positions will be sustained on examination by taxing authorities, based on technical merits of the positions. The Company has identified no income tax uncertainties.

Under Internal Revenue Code Section 382, certain stock transactions which significantly change ownership could limit the amount of net operating carryforwards that may be utilized on an annual basis to offset taxable income in future periods. The Company has not yet performed an analysis of the annual net operating loss carryforwards and limitations that are available to be used against taxable income. Consequently, the limitation, if any, could result in the expiration of the Company’s loss carryforwards before they can be utilized. The Company has not analyzed net operating loss carryforwards under Section 382 to date. As a result of the Helomics acquisition, there may be significant limitation to the net operating loss. In addition, the current NOL carryforwards might be further limited by future issuances of our common stock.

Tax years subsequent to 2001 remain open to examination by federal and state tax authorities due to unexpired net operating loss carryforwards.

Concentration Risk, Credit Risk, Policy [Policy Text Block]

Credit Risk

Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash. The Company places its cash with high credit quality financial institutions and, by policy, generally limits the amount of credit exposure to any one financial institution. As of December 31, 2021. the Company did not have credit risk for cash amounts held in a single institution that are in excess of amounts issued by the Federal Deposit Insurance Corporation.

Risks and Uncertainties Policy [Policy Text Block]

Risks and Uncertainties

The Company is subject to risks common to companies in the medical device and biopharmaceutical industries, including, but not limited to, development by the Company or its competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, and compliance with regulations of the Food and Drug Administration, Clinical Laboratory Improvement Amendments, and other governmental agencies.

The Company has evaluated all of its activities and concluded that no other subsequent events have occurred that would require recognition in the consolidated financial statements or disclosure in the notes to the consolidated financial statements, except as described above and in Note 16 – Subsequent Events.
