PART I

Item 1. Business.

Overview

We are an oncology diagnostics company focused on developing, commercializing and providing DNA-based tests and services to improve the personalization of cancer treatment and to better inform biopharmaceutical companies of genomic factors influencing subject responses to therapeutics. Our vision is to become the oncology diagnostics partner for companies and clinicians by participating in the entire care continuum from bench to bedside. We believe the diagnostic industry is undergoing a metamorphosis in its approach to oncology testing, embracing individualized medicine as a means to drive higher standards of patient treatment and disease management. Similarly, biopharma companies are increasingly engaging companies such as ours to provide information on clinical trial participants’ DNA profiles in order to identify genomic variations that may be responsible for differing responses to pharmaceuticals, and particularly to oncology drugs, thereby increasing the efficiency of trials while lowering related costs. We believe tailored therapeutics can revolutionize oncology medicine through DNA-based testing services, enabling physicians and researchers to target the factors that make each patient and disease unique. We have created a unique position in the industry by providing targeted somatic analysis of tumor sample cells alongside germline analysis of an individuals' non-cancerous cells' DNA as we attempt to reach the next milestone in personalized medicine. Individuals are born with germline mutations and somatic mutations arise in tissues over the course of a lifetime.

Cancer is genetically-driven and constitutes a heterogeneous class of diseases characterized by uncontrollable cell growth. Many cancers are becoming increasingly understood at a molecular level and it is possible to attribute specific cancers to identifiable genetic changes in unhealthy cells. Cancer cells contain modified genetic material compared to normal human cells. Common genetic abnormalities correlated to cancer include gains or losses of genetic material on specific chromosomal regions (loci) or changes in specific genes (mutations) that ultimately result in detrimental cellular changes followed by cancerous or pre-cancerous conditions. Understanding the differences in these genomic changes helps clinicians to identify and stratify different forms of cancer in order to optimize patient treatment and patient management. Therefore, understanding and analysis of cancer at the molecular level is not only useful for diagnostic purposes, but we also believe it can play an important role in prognosis and disease management. We believe technology that can apply predictive information has the potential to dramatically improve treatment outcomes for patients fighting against cancer. Our molecular diagnostic tests for cancer aim to remove subjectivity from the diagnostic phase, and add prognostic information, thus enabling personalized treatments based on cancer analysis at its most basic genetic level.

Our business is based on demand for DNA-based diagnostic services from three main sectors, including cancer centers and hospitals, biotechnology and biopharmaceutical companies, and the research community. Clinicians and oncologists in cancer centers and hospitals seek genomic-based testing since these methods produce higher value and more accurate cancer diagnostic information than traditional analytical methods. Our unique and focused tests aim to provide actionable information that can guide patient management decisions, potentially resulting in decreased costs for cancer centers and hospitals while streamlining therapy selection. Our services are also sought by biotech and biopharma companies engaged in designing and running clinical trials for their value and efficacy in oncology treatments and therapeutics. We believe trial participants' likelihood of experiencing either favorable or adverse responses to the trial treatment can be determined by genomic testing, increasing trial efficiency, subject safety and trial success rates. We aggressively pursue the strategy of trying to demonstrate increased value and efficacy with payors who are trying to contain costs and academic collaborators seeking to develop new insights and cures.

Our go-to market strategy is organized to align with the three aforementioned industry segments. We utilize relatively the same technologies across each of these businesses to deliver results-oriented information important to cancer treatment and patient management. Our tests address the limitations of traditional cancer diagnostic approaches, including reliance on human inspection of specimens and interpretation of clinical measurements, and inter-institutional variability. Our suite of clinical and biopharma services remove subjectivity from diagnoses and additionally provide information on treatment selection that cannot be obtained from anatomic pathology and staining techniques alone. We believe the level of personalized treatment required to optimize a patient's treatment regimen and to maximize clinical trial success rates is only possible through the use of DNA-based molecular diagnostics.

The following table lists our go to market strategy by customer category:

2

Customer Category	Types of Customers	Nature of Services
Clinical Services	• Hospitals • Cancer Centers • Clinics	Clinical services provide information on diagnosis, prognosis and theranosis of cancers to guide patient management.
Biopharma Services	• Biopharma and Biotech companies performing clinical trials	Biopharma services provide companies customized solutions for patient stratification and treatment selection through an extensive suite of DNA-based testing services.
Discovery Services	• Biopharma and Biotech companies • Researchers	Discovery services provide the tools and testing methods for companies and researchers seeking to identify new DNA-based biomarkers for disease.

In 2014, we generated approximately 55% of our revenue from Biopharma Services, approximately 43% from Clinical Services and approximately 2% from Discovery Services, a new line of service launched in 2014.  In 2013, we generated approximately 55% of our revenue from Clinical Services, approximately 40% from Biopharma Services and approximately 5% from government grants. During 2014 we had no government grants.

We utilize relatively the same proprietary and nonproprietary molecular diagnostic tests and technologies across our clinical services, biopharma services and discovery services businesses to deliver results-oriented information important to cancer treatment and patient management. We believe that there is significant synergy in developing and marketing a complete set of tests and services that are disease focused and delivering those tests and services in a comprehensive manner to help with treatment decisions. The insight that we develop in delivering non- proprietary services are often leveraged in the development of our proprietary programs and now increasingly in the validation of our proprietary programs (such as MatBA® and Focus::NGS^TM) for clinical use.

Clinical Services

Our clinical offerings include our portfolio of proprietary tests targeting hematological, urogenital and HPV-associated cancers, in conjunction with ancillary non-proprietary tests. Our proprietary tests target cancers that are difficult to prognose and predict treatment outcomes through currently available mainstream techniques. We provide our proprietary tests and services, along with a comprehensive range of non-proprietary oncology-focused tests and laboratory services, to oncologists and pathologists at hospitals, cancer centers, and physician offices. Our proprietary tests are based principally on our expertise in specific cancer types, test development methodologies and proprietary algorithms correlating genetic events with disease specific information. Our portfolio primarily includes comparative genomic hybridization (CGH) microarrays and next generation sequencing (NGS) panels, and DNA fluorescent in situ hybridization (FISH) probes.

Our comprehensive oncology-focused testing services for cancer are utilized in the diagnosis, prognosis and predicting treatment outcomes (theranosis) of cancer patients and are growing rapidly as clinicians demand more precise and more comprehensive diagnostic evaluation of their patients. We utilize highly skilled scientists, pathologists and hematologists in our laboratory, with 35% of individuals holding advanced degrees. These individuals assist our customers in integrating and technically assessing the testing results for their patients.

The non-proprietary testing services we offer are focused in part on specific oncology categories where we are developing our proprietary arrays and probe panels. We believe that there is significant synergy in developing and marketing a complete set of tests and services that are disease- and treatment-focused and delivering those tests and services in a comprehensive manner to help with patient management decisions. The insight that we develop in delivering the non-proprietary services are often leveraged in the development of our proprietary programs and now increasingly in the validation of our proprietary programs for clinical use.

We believe that we can be successful by offering cancer professionals a fully-integrated menu of oncology- focused proprietary tests and customizable laboratory services. We believe that our proprietary tests provide superior diagnostic and prognostic values than other currently available tests and services. We believe our ability to rapidly translate research insights about the genetics and molecular mechanisms of cancer into the clinical setting will improve patient treatment and management and that this approach can become a key component in the standard of care for personalized cancer treatment.

We currently offer a range of proprietary and non-proprietary services in the following areas:

Proprietary Microarray based testing (MatBA®-CLL, MatBA®-SLL, MatBA®-DLBCL, MatBA®-MCL and UroGenRA®-Kidney)	Our proprietary microarray tests for the detection of chromosomal abnormalities observed in Chronic Lymphocytic Leukemia, Small Lymphocytic Lymphoma, Diffuse Large B-Cell Lymphoma, Mantle Cell Lymphoma and kidney cancer.
Proprietary Next Generation Sequencing testing (Focus::CLL™, Focus::Myeloma™, Focus::Lymphoma™	Our proprietary NGS tests for the diagnosis and prognosis of genomic alterations in Chronic Lymphocytic Leukemia, Myeloma, and B-Cell Non-Hodgkin's Lymphomas.
Molecular Testing	Using quantitative methods, such as polymerase chain reaction, sequencing and mutation analysis, to analyze DNA and RNA to follow progression of disease and response to therapy at the genetic level.
Cytogenetics Testing	A series of methods that analyze human chromosomes in order to identify malignancy.
FISH Testing	Analysis of abnormalities at the chromosomal and gene levels using analyte specific reagents and FED-cleared probes performed on whole specimen or separated purified plasma cells.
Histology Testing	Microscopic examination of stained tissue sections using various special staining techniques.
Cytology Testing	Non-gynecological fluid preparation for microscopic evaluations by a pathologist.
IHC Testing	Analysis of the distribution of tumor antigens in specific cell and tissue types.

Our clinical services strategy is focused on direct sales to oncologists and pathologists at hospitals, cancer centers, and physician offices in the United States, and expanding our relationships with leading distributors and medical facilities in emerging markets. In addition, we intend to continue to focus on partnering with community hospitals, where nearly 85% of all cancers are initially diagnosed, through our program called Expand Dx™, which was specifically designed to meet the needs of community hospitals. We believe our proprietary tests and services will enable community hospitals to optimize and expand their oncology services to better serve their cancer patients and reduce costs associated with cancer care.

We have developed the Summation™ Report which, we believe, provides an integrated view of a patient’s test results and diagnosis in a user-friendly, visually appealing format for clinicians. Our hematopathologists and laboratory directors prepare these Summation™ Reports based on the clinical information and diagnosis provided by our laboratory professionals. All our testing technologies are integrated into a Summation™ Report to allow oncologists to efficiently arrive at a definitive diagnosis and drive complete and effective decisions.

Our principle clinical services leverage and utilize our proprietary tests and testing methods, which include the categories below:

NGS Panels

Next-Generation Sequencing performs massively parallel sequencing (over 100 reads of a selected segment of DNA in one test run) of DNA from cancer cells effectively permitting a highly sensitive analysis of not only the sequence of the genome in cancer cells to reveal mutations and other aberrations associated with a cancer, but also other genomic rearrangements previously unknown to occur in the cancer genome. Translation of these findings for clinical implementation can also be achieved with a high degree of sensitivity using deep sequencing at specific nucleotide sequences and can be translated where applicable into FISH or microarray-based assays depending on the aberrations that need to be detected, to develop more specific tests. Deep sequencing is a technique by which a selected segment of nucleotides is sequenced repeatedly in order to reveal potentially rare genetic changes that may not be discoverable by traditional sequencing methods.

CGH Microarrays

Oligonucleotide-based CGH microarrays are a multiplex technology that allows the attachment of thousands of microscopic spots of DNA onto a surface. The DNA sequences on the microarray can hybridize to multiple genetic aberrations in cancerous tissue and can yield diagnostic and prognostic information of importance to the treatment of the patient from a small amount of patient sample. We believe microarrays provide a powerful approach to distinguishing cancer types and differentiate those more or less likely to recur, progress or respond to specific treatments based upon comprehensive sequence analysis and the ability of one microarray to interrogate multiple cancer subtypes in parallel. Because thousands of individual DNA sequences are being tested by the microarray, analysis involves bioinformatics-based algorithms. Considering the current clinical and societal demand for minimally invasive procedures, we believe the diagnostic and prognostic applications of microarrays are highly desirable.

4

Complete^TM Program

Our Complete^TM program is our branded program offering a unique suite of common and proprietary tests that assist clinicians in determining the best treatment options to improve patient outcomes. Each Complete^TM program integrates the latest diagnostic and prognostic biomarkers across multiple testing methodologies. We offer Complete^TM testing for a number of hematological cancers and solid tumors, including CLL/SLL, DLBCL, MCL, MPN, colorectal, lung and breast cancers.

DNA Probes

FISH-based DNA probes are fluorescently labeled sequences of DNA complementary to a genomic region of interest, which when hybridized to chromosomes, give rise to signals revealing with high sensitivity the presence or absence of a specific genomic abnormality. One probe identifies one specific genomic region. To create higher levels of specificity, multiple probes may be required to identify multiple genomic aberrations in the same cancer cell. Depending on the color scheme and custom design of each FISH-based DNA probe, genomic gain/loss and rearrangements can be detected in cancer specimens of multiple tissue types. Our proprietary FHACT® probe panel for detection and prognostication of HPV-associated cervical cancer and precancerous lesions uses a patented four-probe set to differentiate between cervical lesions likely to progress to cancer and those likely to regress without intervention.

We expect to offer additional proprietary tests as LDTs in other areas of oncology and will seek the required CLIA and state approvals, as well as any FDA approvals that may be required for these tests.

Biopharma Services

Biopharma services include laboratory and testing services performed for biopharmaceutical companies engaged in clinical trials. Our biopharma services focus on providing pharmaceutical companies with oncology specific and non-oncology genetic testing services for phase I-III trials along with ancillary services including biorepository and trials logistics support. These services include DNA and RNA extraction and purification, genotyping, gene expression analyses and biorepository sample storage solutions.

Industry research has shown many promising drugs have produced disappointing results in clinical trials. For example, a study by Princess Margaret Hospital in Toronto estimated that 85% of the phase III trials testing new therapies for solid tumors studied over a five-year period failed to meet their primary endpoint. Given such a high failure rate of oncology drugs, combined with constrained budgets for biopharmaceutical companies, there is a significant need for drug developers to utilize molecular diagnostics to decrease these failure rates. For specific molecular-targeted therapeutics, the identification of appropriate biomarkers potentially may help to optimize clinical trial patient selection and increase trial success rates by helping clinicians identify patients that are most likely to benefit from a therapy based on their individual genomic profile.

Our Select One® offering was created specifically to help the biopharmaceutical community with clinical trials and companion diagnostic development in areas of our core expertise. Oncology drugs have the potential to be among the most personalized of therapeutics, and yet oncology trials have one of the worst approval success rates, hovering at approximately 10%. In an effort to improve the outcome of these trials, and more rapidly advanced targeted therapeutics, the biotechnology and pharmaceutical community is increasingly looking to companies that have both proprietary disease insights and comprehensive testing services as they move toward biomarker-based therapeutics.

In July 2014, the United States National Institutes of Health reported over 83,000 clinical trials were currently being conducted in the United States, and over 12,000 of these trials were actively recruiting participants for studies with oncology pharmaceuticals or biologics. Genomic testing services have been altering the clinical trials landscape by providing biopharma companies with information about trial subjects’ genetic profiles that may be able to inform researchers whether or not a subject will benefit from the trial drug or will experience adverse effects. Streamlined subject selection and stratification, and tailored therapies selected to maximally benefit each group of subjects may increase the number of trials that result in approved therapies and make conducting clinical trials more efficient and less costly for biopharma companies. In 2014, forty-one new drugs were approved by the FDA. This is the highest number of FDA approvals since 1996, and twenty of these drugs were personalized medicines, highlighting the potential value of incorporating genomic information into clinical trial design.

In addition to the tests and services provided to biopharma companies, we are developing NGS panels focused on pharmacogenomics and oncology that will inform researchers of trial subjects' drug sensitivities.

We provide the following services to biopharma companies and researchers conducting clinical trials:

Genotyping and Pharmacogenomics Testing Services

•Over 400 genotyping assays including drug metabolizing enzymes, transporters and receptors

5

•Over 30 validated gene expression assays

•Testing for the FDA’s Pharmacogenomic (PGx) Biomarkers in Drug Labels recommended panel

•Loss of heterozygosity and copy number detection assays

We also utilize our laboratories to provide clinical trial services to biopharmaceutical companies and clinical research organizations to improve the efficiency and economic viability of clinical trials. Our clinical trials services leverage our knowledge of clinical oncology and molecular diagnostics and our laboratory’s fully integrated capabilities. Our Select One^®program integrates clinical information into the drug discovery process in order to provide customized solutions for patient stratification and treatment. By utilizing biomarkers, we intend to optimize the clinical trial patient selection. This may result in an improved success rate of the clinical trial and may eventually help biopharmaceutical companies to select patients that are most likely to benefit from a therapy based on their genetic profile. We believe we are one of only a few laboratories with the capability to combine somatic and germline mutational analyses in clinical trials.

Our Select One ® clinical trial services are aimed at developing customizable tests and techniques utilizing our proprietary tests and laboratory services to provide enhanced genetic signature and more comprehensive understanding of complex diseases at earlier stages. We leverage our knowledge of clinical oncology and molecular diagnostics and provide access to our genomic database and assay development capabilities for the development and validation of companion diagnostics. This potentially enables companies to reduce the costs associated with development by determining earlier in the development process if they should proceed with additional clinical studies. We have been chosen by Gilead Sciences Inc. to provide clinical trial services and molecular profiling of chronic lymphocytic leukemia (CLL) patients. We believe our clinical trial services may allow Gilead and others to improve patient responder selection, thereby potentially increasing the likelihood our customer’s product is approved by FDA. Additionally, through our services we gain further insights into disease progression and the latest drug development that we can incorporate into our proprietary tests and services.

We also provide genetic testing for drug metabolism to aid biopharmaceutical companies identify subjects’ likely responses to treatment, allowing these companies to conduct more efficient and safer clinical trials. We believe pharmacogenomics drug metabolism testing helps deliver the promise of personalized medicine by enabling researchers to tailor therapies in development to differences in patients' genomic profiles.

Discovery Services

Our discovery services provide the tools and testing methods for companies and researchers seeking to identify new DNA-based biomarkers for disease. In 2014, we added discovery services as a new revenue category and for the year ended December 31, 2014 this category accounted for approximately 2% of our total revenue. Discovery services we offer include validation of biomarkers for diseases including cancers, from which tests for diagnosis or prognosis may be established. We also provide consulting, guidance and preparation of samples and clinical trial design. We believe the ability to analyze variations in DNA and interpret these changes into meaningful predictors of disease or indicators of diagnosis is essential to discovering new biomarkers for cancer and targets for therapies.

Market Overview

United States Clinical Oncology Market Overview

Despite many advances in the treatment of cancer, it remains one of the greatest areas of unmet medical need. In 2012, the World Health Organization attributed 8.2 million deaths worldwide to cancer-related causes. In 2014, the World Health Organization projected that over the next two decades this number will rise to 13 million deaths per year. Within the United States, cancer is the second most common cause of death, exceeded only by heart disease, accounting for nearly one out of every four deaths. The incidence and deaths caused by the major cancer categories are staggering. The following table published by The American Cancer Society shows estimated new cases and deaths in 2014 in the United States for the major cancers:

In addition to the human toll, the financial cost of cancer is overwhelming. An independent study published in 2010 and conducted jointly by the American Cancer Society and LIVESTRONG ranked cancer as the most economically devastating cause of death in the world-estimated to be as high as $895 billion globally in 2008. According to the National Institutes of Health, the direct cost of cancer care in the United States is projected to increase from $125 billion in 2010 to $173 billion by the year 2020 taking into account the rising costs of medical care.

United States Clinical Trials Market Overview

The United States is currently the world leader in biopharmaceutical research and development and manufacturing. In 2013 it is estimated that over $50 billion dollars was spent in pharmaceutical research and development, increasing 20% from spending in 2005. The average cost to develop a drug can be as high as $1.2 billion and the approval process from development to market may be as long as 15 years. Since 1980, approximately 63% of life expectancy increases in cancer patients are due to new treatments and oncology medications.

While oncology drugs have the potential to be among the most personalized therapeutics, oncology clinical trials continue to have some of the poorest approval rates. The application of pharmacogenomics to oncology clinical trials enables researchers to better predict differences in drug response, efficacy and toxicity among trial participants, as well as to optimize treatment regimens based on these differences. It is estimated that by 2020, half of all pharmaceutical sales in the United States will be from specialty drugs, a category of drugs including oncology treatments tailored to patients’ genomic profiles. A study by Grand Market Research places theoncology market at 34% of revenue for molecular diagnostics services in 2013, with the pharmacogenomics market following closely at 26.3%. Pharmacogenomics is the study of genetic analysis based on a patient's response to a particular therapy or drug. We believe a growing demand for personalized medicine as a diagnostic tool is a growth driver of this market.

Our Strategy

Our strategy is to serve a diverse group of market participants - biotechnology and pharmaceutical companies, cancer centers and community hospitals, and research centers both public and private - that all require genomic assessment of cancer and biomarker based information to understand and manage the patient, their cancer and customize therapy choices. We believe that our integrated approach to testing combined with our ability to rapidly translate research insights about the genetics and molecular mechanisms of cancer into the clinical setting will improve patient treatment and management will become a key component in the standard of care for personalized cancer treatment.

Our approach is to develop and commercialize proprietary genomic tests and services to enable us to provide a full service solution to improve the diagnosis, prognosis and treatment of targeted cancers and to better predict differences in drug response, efficacy and toxicity among clinical trial participants, as well as to optimize treatment regimens based on these differences. To achieve this, we intend to:

•Continue investing in our portfolio by developing and commercializing additional proprietary genomic tests and services. We intend to continue the development of additional proprietary diagnostic and prognostic tests and services, including next generation sequencing tests, to provide information that is essential to personalized cancer treatment. These tests focus on hematological cancers and solid tumors. To facilitate the development of additional tests and further demonstrate the clinical value of our existing tests, we will continue to develop and expand our collaborations with leading universities and research centers.

•Continue investing in our portfolio by performing additional validation studies with collaborators. We intend to continue performing validation studies on our existing portfolio of proprietary diagnostic and prognostic tests with universities and research institutions. Validation studies demonstrate the clinical utility and efficacy of a test, and the results of validation studies may be used to demonstrate value to clinicians, hospitals and cancer care centers. Validation studies also provide data necessary for approval of the tests by governmental regulatory bodies, and to get our tests approved for reimbursement by third-party payors.

•Continue our focus on translational oncology and drive innovation and cost efficiency in diagnostics by continuing to develop next generation sequencing offerings independently and through our joint venture with Mayo Clinic. Translational oncology refers to our focus on bringing novel research insights that characterize cancer at the genomic level directly and rapidly into the clinical setting with the overall goal of improving value to patients and providers in the treatment and management of disease. We believe that continuing to develop our existing platforms and next generation sequencing panels will enable significant growth and efficiencies. We will continue to develop next generation sequencing panels independently as well as leverage our joint venture with Mayo to advance this diagnostic technology.

•Increase our focus on providing to biopharmaceutical companies and clinical research organizations our proprietary and non-proprietary genomic tests and services through our Select One^® offerings. Oncology drugs have the potential to be among the most personalized of therapeutics, and yet oncology trials have one of the worst approval success rates, hovering at approximately 10%. In an effort to improve the outcome of these trials, and more rapidly advanced targeted therapeutics, the biotechnology and pharmaceutical community is increasingly looking to companies that have both proprietary disease insights and comprehensive testing services as they move toward biomarker-based therapeutics. Our Select One^® offering was created specifically to help the biopharmaceutical community with clinical trials and companion diagnostic development in areas of our core expertise. In our core areas of disease focus, hematologic malignancies, urogenital cancers and HPV-associated cancers, there are over 4,500 active trials in the United States according to clinicaltrials.gov.

•Enhance our efforts to partner with community hospitals. According to the American Hospital Association, there are nearly 5,000 community hospitals in the United States. Community hospitals represent a large target market for our genomic

8

tests and services because approximately 85% of cancer patients in the United States are initially diagnosed in such hospitals as reported to the National Cancer Database. We intend to continue to focus on partnering with such hospitals by targeting our sales and marketing efforts on this important customer segment though our branded Expand Dx™ program.Our Expand Dx™ program for community hospitals is a suite of diagnostic and consultative services offered on a collaborative basis to expand and optimize the oncology diagnostics services and personalized cancer treatment provided by community hospitals so that such hospitals can retain their cancer patients. Our Expand Dx™ program focuses on enhancing the quality and increasing the efficiency of the community hospital’s oncology diagnostic process, including billing, turnaround time for diagnostic tests, diagnostic procedures and training and assistance in the use of additional biomarkers for their routine cancer testing. We believe that through our Expand Dx™ solution, community hospitals and laboratories can get cost-effective access to leading-edge diagnostic tests and specialized testing capabilities of our clinical reference laboratory. Our sales force works with our laboratory directors as a team to market our Expand Dx™ solution to community hospitals, geographically focused on the eastern and mid-western United States.

•Increase our geographic coverage by expanding our scalable sales and marketing capabilities. We currently have a specialized team of sales professionals with backgrounds in hematology, pathology, and laboratory services. We intend to continue expanding our sales force in order to provide increased geographic coverage throughout the United States. Additionally, we intend to develop and continue to expand both our domestic and international footprint through our recent acquisitions in North Carolina, USA and Hyderabad, India, and by focusing on emerging markets by seeking additional leading local partners to market and sell our tests and services.

•Reduce the costs associated with the development, manufacture, and interpretation of our proprietary genomic tests and services. We successfully migrated key components of our probe manufacturing to India in 2013, which reduced the labor costs involved and increased manufacturing yield and flexibility. In 2015, we will continue to assess how geographic advantage can help us improve our cost structure.

•Work with health care providers and payors to demonstrate the value of our testing in providing cost efficient and accountable care. We are actively involved in dialog with key payers, cost management organizations and insurance providers to demonstrate the value and effectiveness of our approach in genomic assessment of complex tumor systems.

•Continue offering our proprietary tests in the United States as laboratory-developed tests (“LDTs”) and internationally as CE-marked in vitro diagnostic medical devices. As part of our long-term strategy, we may seek Food and Drug Administration (“FDA”) clearance or approval to expand the commercial use of our tests to other non-affiliated laboratories and testing sites, or as may be required by developing FDA regulations. We believe it would likely take two years or more to conduct the studies and trials necessary to obtain approval from FDA to commercially launch our proprietary tests outside of our clinical laboratory.

Our Competitive Advantages

We believe that our competitive advantages are as follows:

•Our proprietary and clinically relevant genetic tests are the first to address several complex cancers that are difficult to prognose and where it is difficult to predict treatment outcomes using currently available technologies. Two of our marketed tests are the first to address several under-served, complex cancers. MatBA®-CLL is, to our knowledge based on our informal communications with New York State Department of Health personnel, the first microarray to have been approved by the New York State Department of Health for diagnostic treatment and management of CLL. In addition, in 2014 we launched Focus::CLL^TM, the first NGS panel designed to specifically target genomic alterations clinically associated with CLL. FHACT^®, our proprietary HPV-associated cancer test, is the first multi-region DNA probe to identify and stage HPV-associated cancers, which includes cervical, anal and oropharyngeal cancers.

•We have collaborative relationships with leading research centers, medical centers and oncology groups. Our collaborations with leading cancer centers provide us with a number of benefits, including valuable access to patient samples, data for validation studies and a pipeline of innovation. As of December 31, 2014 we have 19 active collaborations with cancer centers and academic institutions. Oncospire Genomics, our joint venture with Mayo Clinic, focuses on developing oncology diagnostic services and tests utilizing next-generation sequencing, particularly for lung cancer, multiple myeloma and follicular lymphoma. With respect to marketing, we can leverage the brand name recognition of our academic and research center collaborators when selling to our customers. With regard to research and development, our collaborations provide us with the fundamental science and research that underpin the development of our diagnostic tests and insight to maximize the utility of our tests in the clinical setting.

•Our tests provide more information than existing tests to enable a more personalized treatment plan and to provide more actionable information for clinical trials for development of oncology drugs. Our tests are designed to provide an earlier, more accurate and more complete diagnosis, which potentially leads to better treatment outcomes and lower health care costs. For example, MatBA®-CLL evaluates a set of five biomarkers not previously assessed in CLL and also allows a more accurate interpretation of the loss at chromosome 13q as a sole abnormality than previously possible. Our FHACT^® test for HPV-associated cancers is the only four-color DNA-FISH probe that can be used for cervical cancer screening as additional triage before colposcopy. Our Focus::CLL^TMNGS panel is a unique test that asses seven genes with clinical relevance to prognosis, disease management and treatment selection, and has an analytical sensitivity of 5%, allowing it to detect changes in DNA that occur at very low frequencies and may be missed by other technologies.Our proprietary tests also lead to more actionable information for clinical trials for development of oncology drugs.Through our Select One® offering and biopharma services we aim to identify genomic differences that can predict patient responses to drugs, enabling personalized oncology therapy regimens.

•Our genomic tests are not platform dependent. The biology and algorithms behind our tests are adaptable to multiple instrumentation platforms, allowing us to incorporate our tests into a variety of existing clinical laboratory infrastructures without additional capital investment. We have currently optimized our microarray tests for the Agilent platform. However, we believe that we can migrate to other similar platforms, including next gen sequencing, without significant modification. Our NGS panels are able to be run on both Illumina and Ion Torrent platforms.

•Our tests are designed for a wide range of sample types and sample preparation methods and we have the ability to test on FFPE tissue samples, which accelerates the time required to validate, develop and patent new tests. We can currently process specimen types that include blood, bone marrow and tissue, including fresh, frozen and formalin-fixed paraffin-embedded (FFPE) tissue samples. The ability to interrogate a wide variety of sample types increases clinical adoption of our tests and allows the health care provider to quickly and efficiently integrate our tests into its established workflow. This integration with existing oncology and pathology workflow and tissue analysis methods is integral to ensuring near term adoption. For several reasons, we have designed our tests for FFPE tissue samples. For decades, archival FFPE has routinely been used to preserve cancer samples and offers a wealth of information and collaboration potential in comparison with fresh or freshly prepared samples. Our use of FFPE has three important consequences. First, it significantly increases the datasets of samples that can be used to validate our products, leading to more robust and reliable diagnostic tools. Second, it permits utilization of FFPE in a clinical setting, where often it is the only specimen available for study. This is of particular importance totumors diagnosed using minimally invasive technologies where often very small biopsy material is available for diagnostic and prognostic studies. Third, it affords enrichment, or more specific targeting within, the sample to be analyzed, increasing the probability with which genomic aberrations will be detected for any given specimen.

•We offer consultative, oncology-centered laboratory and clinical trial services. Our specimens are tested and interpreted by highly qualified oncology-focused laboratory professionals, many of whom hold MDs and PhDs. Because our clinical staff is highly specialized in oncology, we are better positioned to consult with our oncologist customers and biopharma clients to help them derive maximum value from the diagnostic and prognostic data generated by our tests.

•Our global laboratory infrastructure provides us with access to emerging clinical and biopharma markets. Access to emerging clinical and biopharma markets in India and China enables our participation in a robust and diverse client base outside of the United States. We have recently begun to provide clinical and research services to hospitals, government centers and biopharma companies in India and are engaged in clinical trials test services in China.

Our Proprietary Genomic Tests and Services

We currently develop and produce a variety of platform-independent DNA-based genomic tests: microarrays, probes and next generation sequencing panels. Each is directed at identifying specific genetic aberrations in cancer cells that serve as markers for diagnosis, prognosis and theranosis.

We offer microarrays, next generation sequencing and FISH probes because each serves a unique diagnostic or prognostic function. FISH- based tests, or probes, offer great sensitivity while microarrays provide a more comprehensive analysis of the cancer genome, and NGS panels offer a method of detecting mutations or chromosomal aberrations of lesser frequency.

FDA clearance or approval is not currently required to offer these tests in our laboratory once they have been clinically and analytically validated and approved by the appropriate regulatory bodies. We seek licenses and approvals for our laboratory facility and for our LDTs from the appropriate regulatory authorities, such as the CMS, which oversees CLIA, and various state regulatory bodies, including the New York State Department of Health. We will seek FDA clearance and approval as may be required in the future dependent upon the FDA's final guidelines in its decision to regulate LDTs. At the federal level,

10

certain proprietary tests must be part of proficiency testing programs approved under CLIA in order for us to be able to bill government payor program beneficiaries, such as Medicare patients, for such tests. In addition, certain states, such as New York, require us to obtain approval of our proprietary tests in order for us to collect patient specimens from such state.

We have obtained CE marking for FHACT®, which entitles us to market the test in the European Economic Area (which includes the 27 Member States of the EU plus Norway, Liechtenstein and Iceland). We anticipate that we will need to conduct additional developmental activities for this test and to submit it for regulatory clearance or approval by FDA or other regulatory agencies prior to commercialization outside of our reference laboratory in each of the markets where we plan to introduce them. FHACT® is our four-probe set used to detect genomic biomarkers indicative of HPV-associated precancer and cancer of several tissue types including cervix and pharynx. FHACT® has received two United States patents, covering the combination of genomic probes as well as its clinical use in patient samples.

The following diagram portrays our proprietary programs:

Hematological Cancer Tests: MatBA® and Focus::NGS™

As a group, hematologic cancers (cancers of the blood, bone marrow or lymph nodes) display significant clinical, pathologic and genetic complexity. Current diagnosis relies mostly on pathologic examination, flow cytometry and detection of only a few genetic markers. Importantly, the clinical course of the six main subtypes of these neoplasms ranges from indolent (follicular lymphoma) to aggressive (diffuse large B-cell lymphoma, mantle cell lymphoma and multiple myeloma), or mixed (chronic lymphocytic leukemia/small lymphocytic lymphoma, or CLL/SLL). Currently most risk-stratification for treatment decisions is based on clinical features of the disease. Few molecular prognostic biomarkers are utilized in a clinical setting. There is unmet medical need for robust biomarkers for the diagnosis, prognosis, theranosis and overall patient management in B-cell cancers. Given the higher frequency of these malignancies in the United States than in other countries due to relatively

11

long lifespans and an aging population, we expect significant clinical demand for MatBA® and Focus::NGS™. Additionally, the increasing number of clinical trials in malignancies of blood and bone marrow is driving demand and usage of our tests and services that are focused on hematological cancers.

MatBA® is the first targeted oligonucleotide-based microarray we developed for the analysis of genomic alterations in mature B-cell neoplasms to determine prognosis and theranosis. MatBA® incorporates a common architecture of specific genomic regions that can be applied across the seven major mature B-cell neoplasms. Mature B-cell neoplasms account for approximately 7% of all cancers diagnosed in the United States annually and for approximately 6% of all estimated cancer-related deaths. An estimated 761,600 people in the United States are living with, or are in remission from, mature B-cell neoplasms. They are the fifth most common malignancy in both males and females, and the incidence is rising.

MatBA® is designed to detect genomic copy number changes in mature B-cell neoplasms either solely or in a unique combination, thus assisting the clinician in the management of a patient’s disease. The test relies on the comparative genomic hybridization of fluorescently differentially-labeled normal DNA and DNA extracted from the cancer specimen (array-CGH). Array-CGH utilizes minimal biopsy material and uses DNA as the analyte (the component whose properties are being measured), which is more stable, as compared to RNA used in other array detection methodologies. Both are important considerations for the ever increasing demand for less invasive procedures for diagnostic and prognostic purposes. Additionally, we have optimized the utility of the MatBA® array-CGH so that it can be routinely applied to the study of a range of specimen types including blood and bone marrow and FFPE biopsy specimens, which are often the only specimen available for analysis of Follicular Lymphoma (FL), Diffuse Large B-Cell Lymphoma (DLBCL) and Mantle Cell Lymphoma (MCL). With the exception of Chronic Lymphocytic Leukemia (CLL), biopsy/surgical procedures are rarely performed for B-cell neoplasms prior to the initiation of treatment, thus limiting the amount of tissue available for testing prior to deciding on the initial treatment regimen.

MatBA® was custom-designed to represent 80 regions of the human genome which have diagnostic and/or prognostic value in one or more of the mature B-cell neoplasm subtypes as identified through our research and analysis efforts. Unlike other technologies such as FISH, array-CGH using MatBA® simultaneously permits the detection of genomic gains and losses at multiple locations on a chromosome (loci) that characterize the mature B-cell neoplasm subtypes. For each subtype of B-cell neoplasm, cohorts of specimens with full clinical annotation are evaluated using MatBA® to identify novel associations between single and weighted combinations of genomic gains/losses and clinically relevant endpoints, including time to first treatment, treatment response, progression-free survival and overall survival, and to validate previously known associations. It is these associations, we believe, that provide valuable assistance to clinicians in risk stratification and guiding treatment plans for patients with these cancers. In 2014 we updated MatBA®-CLL/SLL to provide greater clarity of risk outcome for patients.

Focus::NGS™ is our family of next generation sequencing tests developed for the analysis of genomic alterations in hematological and other cancers to determine, guide and inform diagnosis, prognosis and theranosis. The tests rely on massively parallel sequencing, which is able to detect biomarker mutations and aberrations that are present at very low levels and which may be missed by other, less sensitive methodologies. In 2014, we launched our proprietary Focus::CLL™ panel for CLL and small lymphocytic leukemia (SLL). This panel is the only test that assesses 7 genes in a single test, providing clinically relevant data for prognosis, disease management and treatment selection. The panel is available both for routine clinical patient diagnosis and management, as well as for patient stratification in clinical trials for CLL or SLL. In addition to being offered for clinical use, the Focus::NGS™ panels became available in the fourth quarter of 2014 through our Select One^® clinical trial offering. In 2014 Focus::CLL™ was chosen for use in a global clinical trial by a leading biotechnology company.

In addition to our Focus::CLL™ NGS panel, we are in developmental phases for two additional NGS panels for hematological cancers. Our Focus::Myeloid™ panel is designed to target 54 genes, and we believe it will provide important prognostic information for myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML), as well as diagnostic and prognostic information for myeloproliferative neoplasms (MPN). MDS are a group of bone marrow disorders in which the bone marrow does not produce enough healthy blood cells. Approximately 30% of patients diagnosed with MDS will progress to AML, which is a cancer of the myeloid line of blood cells characterized by rapid growth of abnormal white blood cells which interferes with the normal production of other blood cells. MPNs consist of a group of diseases where there is an overproduction of different types of blood cells. The form of MPN is defined by the type of cell that is overproduced. MPNs also have a high possibility of progressing to AML depending on the mutations responsible for the MPN. AML is the most common acute leukemia in adults and its incidence increases with age. AML is expected to account for approximately 20,800 new leukemia cases in 2015, and its prevalence is expected to increase as the population ages.

Focus::Lymphoma™ is our NGS panel in development for B-cell lymphomas, a type of Non-Hodgkin lymphoma. The panel targets 220 genes known to be associated with diagnosis, prognosis and patient treatment response based on their mutational

12

frequency and their potential to interact with cellular pathways known to be dysregulated in these diseases and associated with treatment success and resistance. B-cell lymphomas are a group of approximately one dozen different cancers that are the result of over proliferation of B cells. B-cell lymphomas may either be indolent or aggressive, and diagnosis and staging of the cancer is essential for appropriate diseases and treatment management. In 2014, approximately 60,100 cases of B-cell lymphoma were diagnosed in the United States and the incidence of this disease is expected to rise as the population ages.

We are also actively developing two solid tumor NGS panels. We are designing a cancer HotSpot NGS panel that targets 50 genes associated with cancer development in various tissue types, and which have been identified by scientific literature to play a role in patient response to cancer treatments as well as provide information on likelihood of survival and cancer recurrence. Our pharmacogenomics (PGx) panel in development targets 1885 DNA changes associated with patient drug response. Through detection of these changes, the PGx panel can provide information about a patient's ability to metabolize pharmaceuticals, including anti-inflammatory drugs and warfarin, among others. This information is important to determining drug dosage and to avoid adverse reactions to medications.

MatBA® Microarrays and Focus::NGS™ Panels offered as LDTs

We offer the first application of MatBA® for prognostication in one subtype of mature B-cell neoplasm, CLL, where about half of patients experience indolent disease, or slow progression, and the remaining half, a relatively aggressive progression. MatBA®-CLL provides important genetic-based information to guide clinical management of this disease. The test results are reported out in a unique format that allows ease of interpretation by the hematologist or oncologist. MatBA®-CLL is included in the tests we can provide under our New York laboratory and CLIA licenses. New York is one of only a few states that separately reviews LDTs for clinical and analytical validity. To date there are only a few companies that have commercially available oncology microarrays and, to our knowledge based on our informal communications with New York State Department of Health, MatBA®-CLL was the first oncology microarray approved for commercial use by the New York State Department of Health.

We offer Focus::CLL™ for prognostication in CLL and SLL to provide genetic-based information to guide clinical management of these diseases. Similar to CLL, SLL is experienced in patients as either indolent disease or active progression, which require different approaches to treatment. Therefore, it is important for clinicians and oncologists to be able to differentiate between disease types that are likely to progress or not. Based on the Focus::CLL™ panel test results, each patient may receive the most suitable treatment tailored to their unique cancer subtype. Focus::CLL™ is included in the tests we can provide under our CLIA license, effective December 2014, and we are engaged in the application process for New York laboratory approval.

Approximately 14,600 new cases of CLL are expected to be diagnosed in the United States in 2015, and importantly, over time these cases undergo evolution, requiring risk stratification and guidance on patient management issues at multiple points during the course of the disease. Prior to the introduction of MatBA® and Focus::CLL™, clinicians relied on the assessment of the gain or loss on only four chromosomal regions and potentially one gene mutation when testing for and stratifying a CLL patient. MatBA® improves on this by identifying information on five additional chromosomal regions, providing more valuable diagnostic data and critical information about the risk of progression and overall prognosis of the patient. In particular, because MatBA® has greater resolution than that available with prior tests, we can interrogate two different regions or loci on the 13q chromosome. Loss of one specific locus or loss of both loci are in some circumstances believed to have differing prognostic value, hence the importance of being able to evaluate both loci. Also, loss of 13q as a sole abnormality is associated with a lower risk of progression and overall favorable outcome. With the increased capacity of MatBA® to assess abnormalities in multiple regions of the genome not usually assessed by other technologies, our studies have indicated that up to 23% of cases that would have shown 13q loss as a sole abnormality when assessed by FISH technologies do in fact have additional abnormalities. For these cases, the “favorable outcome” that would have been reported to the clinician was not accurate, leading to a change in the prognosis and consequently decision-making by the clinician regarding the management of these patients. In addition we have identified novel biomarkers using MatBA® that are associated with a poor outcome in CLL. These include gains at 2p, 3q and 8q and a loss at 8p. Additional prognostic regions have been identified and are undergoing validation. These will be reported, further driving the value of more comprehensive genomic assessment of the patient’s cancer. We believe this type of genomic assessment of the patient’s cancer also saves the health care system thousands of dollars per year per patient as a result of improved patient management and more targeted therapeutic intervention.

Kidney cancer: UroGenRA^®-Kidney and Focus::Renal^TM 

There is an unmet clinical and patient need for improved diagnosis, prognosis and theranosis, including more detailed and staging information, in kidney cancers, where biopsy materials are increasingly scarce. The cumulative number of annual new

13

reported cases for kidney cancers is estimated at 61,560 for 2015 according to the American Cancer Society. Although generally characterized by early stage detections, these cancers still represent a major health risk, a significant variability in patient outcome, which can be better managed through genomic assessment of the tumor(s), and a substantial medical cost burden to the public with the high rates of incidence and ongoing patient management needs. Developing sophisticated, state-of-the-art molecular tests that enable more accurate diagnosis and/or prognosis of these cancers will not only benefit the patients by offering more appropriate treatments, but also effectively reduce the unnecessary medical cost associated with surgery, long-term follow-up surveillance, or therapy after the treatment.

The UroGenRA^® microarray, which has been validated in collaboration with Memorial Sloan-Kettering Cancer Center, will provide diagnostic and prognostic analysis for kidney, bladder and prostate cancer. We launched UroGenRA^® in 2013.

UroGenRA^® is a proprietary CGH-based array which will serve as a platform for the diagnosis, prognosis and theranosis of kidney cancers. It was designed to detect gains and losses that frequently occur in genetic material in these cancer types and has the potential to differentially diagnose and/or stratify patients to assist and guide clinical management. It represents 101 regions of the human genome potentially with diagnostic, prognostic and/or theranostic value. UroGenRA^® is specifically designed to classify renal tumors into the four main subtypes (clear cell, papillary, chromophobe and oncocytoma), which is critical to patient management and treatment protocols. This allows the clinician, especially in cases where there is limited biopsy material, to diagnose renal cancer and accurately classify it into the correct subtype, (ii) provide rationale for selection among surgical and non-surgical intervention or ablation, (iii) stratify patients based on prognostic information for the advancement of renal cancer into local or regional cancer which then guides decisions on surgical intervention, and (iv) guide drug trial decisions in those with metastatic disease or “unclassified” renal cancers.

We developed a study with two leading academic cancer centers for which we obtained and used a group of 200 specimens comprising four kidney cancer subtypes to further develop and validate the algorithm of copy number variation known to be associated with these tumors that gives the best ability to differentiate among these four subtypes. These copy number changes are already known to minimally include loss in six regions of chromosomes among these four types and gain in three other regions and we were able to define additional and specific regional copy number variations. The derived proprietary renal cancer diagnostic algorithm or decision tree based on UroGenRA^® copy number alterations was validated for diagnostic potential in the IRB-approved study of over 50 image-guided needle biopsies and compared with the sensitivity and specificity obtained by our proprietary FISH-based assay for kidney cancer, FReCaD™.

UroGenRA^®-Kidney is now available as a LDT available under our CLIA and New York laboratory licenses. At the current time, validation of the clinical utility of UroGenRA^® is further advanced for kidney cancers than for prostate and bladder cancers, because we are able to leverage research and insights used in the clinical validation of FReCaD™ in our development activity for the UroGenRA^® indication for kidney cancer.

In 2014, in a collaboration with Memorial Sloan-Kettering Cancer Center, we identified genomic signatures that can differentiate between patients with clear cell renal carcinoma (ccRCC), a type of kidney cancer, whose disease is likely to relapse or metastasize, or spread to other tissues in the body. The study analyzed 144 ccRCC samples and the genomic signatures identified by this collaborative effort have the potential to allow for better risk stratification and treatment selection for patients with metastatic ccRCC. ccRCC is the most common type of kidney cancer, with approximately 43,000 cases diagnosed in the US each year. Identifying patients whose disease is likely to relapse or metastasize is essential for planning appropriate treatment strategies and improving survival outcomes. We plan on integrating the genomic signatures identified in this study into an NGS panel for kidney cancer, Focus::Renal^TM..

Proprietary DNA Probe

FHACT^® HPV-Associated Cancer Test

We have developed a proprietary, 4-color FISH-based DNA probe designed to identify the gain of the three most important chromosomal regions that have been implicated in cancers associated with HPV: cervical, anal and oropharyngeal. According to the National Cancer Institute, about 55 million PAP smear tests to detect HPV are performed in the United States each year. It is estimated that approximately 2 million patients have abnormal PAP smear test results and are referred for biopsy/colposcopy as a result of such tests. However, only 0.6%, or approximately 12,000 of these patients will develop cervical cancer. It is believed that early detection of HPV-associated cancers and lesions most likely to progress to cancer could eliminate unnecessary biopsies/colposcopies and thereby reduce health care costs.

FHACT^® is designed to determine copy number changes of four particular genomic regions by FISH. These regions of DNA give specific information about the progression from HPV infection to cervical cancer, in particular the stage and subtype of disease. FHACT^® is designed to enable earlier detection of abnormal cells and can identify the additional genomic

14

biomarkers that allow for the prediction of cancer progression. FHACT^® is designed to leverage the same PAP smear sample taken from the patient during routine screening, thus reducing the burden on the patient while delivering greater genomic-based information to the clinician. We in-license a biomarker from the National Cancer Institute that is used in our FHACT^® probe.

In conjunction with the National Cancer Institute, we are performing a blinded study to evaluate the effectiveness of FHACT® for both anal and cervical cancers associated with the HPV virus that involves over 1,000 specimens. We completed study on over 300 cervical specimens and the data has been provided to National Cancer Institute. The results from this study along with the methods and values validated by this work will be used to enhance the product performance of FHACT®. Upon review of the data analysis and results, National Cancer Institute will provide additional anal tissue samples. This data has been used for validation of the assay and development of automatic analysis for the FHACT® probe. We continue to validate FHACT® for anal and oropharyngeal cancers (cancers of the mouth and throat) using specimens from the National Cancer Institute and are actively seeking additional collaborations to further validate the clinical utility of FHACT®.

We continue further clinical validations in collaborations that have been established with the University of Iowa and with Kamineni Hospital in Hyderabad, India to further strengthen the claims and data for use of FHACT^® as a staging and prognostic tool for cervical cancer in both the United States and in emerging markets. The sensitivity of FHACT^® was presented as a poster at the 27th International Pappillomavirus Conference in Berlin, Germany in 2011. The publication demonstrated that by using FHACT^® over 90.9% sensitivity can be achieved as a screening tool for cervical intraepithelial neoplasia of 2nd degree or higher (known as CIN2+), which is a critical milestone in the development of cervical cancer, after which stage treatment choices are limited.

In 2012, we made FHACT^® available outside the United States as a diagnostic tool for cervical cancer in certain emerging market countries, including India. Cervical cancer is the third most common cancer among women worldwide, with one-fifth of global cases originating in India. The World Health Organization projects that cervical cancer deaths will rise to 320,000 in 2015 and 435,000 in 2030. In many emerging economies, cervical cancer is the most common cancer that affects women, and 80% of deaths from cervical cancer occur in developing countries. We began making FHACT^® available for clinical use in the United States in 2013. We actively market FHACT® to hospitals, cancer clinics and individual physicians' offices for testing cervical cell samples obtained from patients' pap smear liquid.

In October and November of 2014, we were granted U.S. Patent Nos. 8,883,414 and 8,865,883, respectively, by the United States Patent and Trademark Office for FHACT®. The '883 patent covers the 4-probe design and the '414 patent covers FHACT^® for use to detect HPV-associated cancer and precancerous lesions in clinical samples.

Oncospire Genomics, LLC: Our Joint Venture with Mayo Clinic

On November 7, 2011, we entered into an affiliation agreement with the Mayo Foundation for Medical Education and Research, pursuant to which we agreed to form a joint venture with Mayo. We funded the joint venture with an initial $1.0 million contribution in October 2013. The objectives of the joint venture entity will be to try to discover and validate biomarkers in lung cancer, multiple myeloma and follicular lymphoma utilizing next-generation sequencing with a possible expansion into other solid tumors, such as esophageal, head and neck and breast cancers. Additionally, the joint venture entity will engage in biomarker discovery utilizing Mayo’s next-generation sequencing facility and the development of commercial products in the form of diagnostic products and services, as well as early stage therapeutic markers.

The aggregate purchase price was approximately $1.9 million payable to the different shareholders of BioServe as follows: (i) Ventureast will receive a payment equivalent to the cash value of 84,278 shares of the Company’s common stock at the time of payment, payable in 30 months or sooner if the Company effects a public offering of its common stock prior to that time, (ii) approximately $100,000 was payable in cash, and (iii) approximately 31,370 shares of the Company’s common stock were issued. We also assumed approximately $160,000 in indebtedness. The source of the cash payables at closing was the Company's working capital. The computation of the purchase price is included in footnote 1 to the Consolidated Financial Statements. The amounts used in computing the purchase price for financial statement purposes differ due to fair value measurement conventions prescribed in accounting standards. The future payment described in (i) above is subject to periodic adjustment due to changes in the Company's share price. Any changes are reflected in the Consolidated Statement of Operations.

India Clinical Oncology and Biopharma Market Overview

India has a growing market for molecular diagnostics and oncology services. According to a 2010 study published in the Asian Pacific Journal of Cancer Prevention, each year, more than 1 million new cases of cancer are diagnosed in India, and incidence rates are expected to rise by more than 72 percent by 2025. In those cancer types for which we provide diagnostic and prognostic proprietary tests and services, incidences are also predicted to rise steadily over the next decade even while the population is expected to experience a decrease in population growth rate. Gynecological cancers account for approximately 30% of the total cancer burden among women in India. Furthermore, over 80% of cancers in India are first detected in advanced or terminal stages, indicating an important opportunity in this market for DNA-based oncology diagnostic tools that can provide early-stage information to guide treatment resulting in greater survival rates.

It is estimated by the India Brand Equity Foundation that the Indian biopharma and biotech markets are expected to experience over a 20% increase in CAGR by 2017 due to favorable business conditions and increasing government expenditures in these sectors. The biopharmaceutical services segment accounted for the largest share of sector growth in 2013 and 2014, accounting for approximately 64% of total revenues, and experienced the highest growth rate in this period, with an approximately 17% CAGR. Over the next decade, growth in this industry is anticipated to come largely from India’s strong position in biosimilars and molecular diagnostics, as well as from personalized medicine. The Indian government has been increasing spending on the biotech and biopharma sectors through 5-year budget allocation plans aimed at research and development as well as health care.

In the first quarter of 2014 we launched FHACT® in collaboration with Kamineni Hospitals in Hyderabad, India for the detection and management of cervical cancer. This was the first broad-scale adoption of FHACT® in India. The launch culminates a collaboration that was begun in July 2013 to assess the value and clinical utility of FHACT® in India.

China Clinical Oncology and Biopharma Market Overview

Cancer is one of the leading public health problems in both urban and rural China. The disease is among the leading causes of death in the Chinese population, representing approximately 25% of all deaths in urban areas and 21% in rural areas. Over the past 30 years, the risk factors for cancer in China have been increasing, including an aging population, decreased environmental conditions and westernization of diet and lifestyle. The Chinese biopharma is currently the third largest pharma market globally, after the United States and Japan. With more than one fifth of the world’s population, China is an important market for biopharma and biotech products and China’s minister of health has pledged that the country will spend an additional $11.8 billion to advance biotech innovation from 2015 to 2020 in its 13^th five-year plan. Our Shanghai laboratory performs clinical trials services for biopharma companies in China, where governmental regulations prevent human samples from being exported from the country.

Test Development Process

Our proprietary microarrays, DNA probes and NGS panels have been, and continue to be, developed in conjunction with

17

leading academic and clinical research centers to ensure that the needs of the clinical community are being met with the latest research on genomic alterations that cause, lead to, or are related to the development of cancer. We undergo a thorough research and validation process to ensure we are providing diagnostic and prognostic information that is clinically relevant and accurate. In our experience the time-frame for this process from design through development and market launch can be between 18 to 40 months based on complexity of the disease, the specific clinical claims being pursued and the availability of high quality samples with strong clinical correlations. We monitor and review the process in four stages as detailed in the table below:

Stage 1: Research and Development

• We conduct extensive research of peer-reviewed publications and other disease-specific literature and public information databases for information regarding genomic abnormalities as hallmarks and references for particular cancers and clinical correlations.

• Within a cancer type, the observed gains, losses or other aberrations and rearrangements of genetic material are recorded and noted when reported to have diagnostic or prognostic potential. During this process, which is technology and platform agnostic, we extensively cross-analyze our findings in the literature with published data sets across a variety of technologies.

• Finally, we assess the merits of these findings internally with our research and development teams and with our scientific advisory board, when applicable, so that we can assure robust genomic coverage as we proceed into clinical development.

Stage 2: Clinical Development

• We design a targeted array, probe panel or NGS panel based on the information gathered from the literature and database searches and review. A team of our scientists then seeks to refute the evidence compiled in the literature search process, serving as a system of checks and balances.

• Once that process is complete, we design a test platform based on its application within a particular cancer. For example, the kidney array is designed to subtype among the four main types of kidney cancers at various stages in the treatment of the patient. Within one test, we may be assessing three to four different subtypes of a cancer and for different applications, ranging from differential diagnosis to prognosis to prediction of therapeutic response.

• During this stage we select and refine the targeted regions and their potential suitability for analysis.

Stage 3: Commercial Development

• This process involves validating the performance characteristics of the test, as well as developing protocols for the use of the test for the intended specimen. The quality assurance process notes reproducibility, accuracy, sensitivity, and specificity, and potential compliance to ranges of normalcy and reportability.

• We also compare data obtained for specimens and cell lines across different technology platforms to ensure accuracy of our processes. In this process, we confirm and validate the genomic biomarkers in independent clinically relevant datasets. During this process we also begin to develop the decision trees and algorithms, which are core to our intellectual property that guide the diagnostic and prognostic value of the test.

• We conduct trials which help to validate its design and usage. For this validation process, we partner with leading cancer institutions and regional cancer centers.

Stage 4: Market Entry and Launch

• After commercial development is completed and prior to market launch, we take several steps to prepare for marketing our tests as LDTs. We create standard operating procedures and quality assurance and quality control measures to ensure repeatability and high standards of quality. We train our staff on the interpretation and use of the data.

• Licenses and approvals for our laboratory to use LDTs are obtained from the appropriate regulatory authorities, such as the Centers for Medicare and Medicaid Services (“CMS”), which oversees CLIA, and state regulatory bodies. Before we CE mark our tests we also need to assess the conformity of our tests with the essential requirements of the European In Vitro Diagnostic Medical Devices Directive.

• We will also need to complete additional activities to submit each of these tests for regulatory clearance or approval prior to commercialization in each of the international markets where we plan to introduce them.

Research and Development Expenses

We incurred research and development expenses of $4.6 million, which represented 45% of our net revenue, for the year

18

ended December 31, 2014; $2.2 million, which represented 33% of our net revenue, for the year ended December 31, 2013; and $2.1 million, which represented 49% of our net revenue, for the year ended December 31, 2012. Research and development expenses represented 22% of our total operating expenses for the year ended December 31, 2014, 22% of our total operating expenses for the year ended December 31, 2013, and 26% for the year ended December 31, 2012. Major components of the research and development expenses included direct personnel costs, laboratory equipment and consumables and overhead expenses.

Sales and Marketing

Our sales and marketing efforts consist of both direct and indirect efforts, with the majority of efforts focused on direct sales in both the United States and India. The table below summarizes our sales approach by geography and customer segment:

United States	Clinical Sales	• Collaborate with leading research universities and institutions that enable the validation of our new tests • Work with community-based cancer centers that need a reliable and collaborative partner for genomic-based cancer testing • Build relationships with individual thought leaders in oncology, hematology and pathology to deliver services that provide value to their patients.
	Biopharma Sales	• Collaborate with scientific development teams at pharmaceutical companies on studies involving translational medicine and genotyping. • Build relationships in the research and development segment to identify partners with a need for biomarker discovery studies.
India	Clinical Sales	• Develop relationships with oncologists, corporate hospitals and reference labs, as well as with physicians in local clinics. • Engage the population of oncology patients in India, where a majority of oncology drugs are paid for out-of-pocket.
	Biopharma & Discovery Sales	• Work with academic and research institutions for validation of our tests in the Indian population. • Collaborate with scientific development teams at biopharma companies and government agencies on studies involving genomic-based tests and services.

Our sales force professionals have backgrounds in hematology, pathology, and laboratory services, and have an average of 20 years of experience in clinical oncology sales, esoteric laboratory sales from leading biopharmaceutical, pharmaceutical or specialty reference laboratory companies. We currently have a team of eight sales professionals in the United States and seven in India. We plan on continuing to grow this specialized, oncology-focused sales force and support it with clinical specialists who bring deep domain knowledge in the design and use of the tests and services that we currently offer, and those we plan on offering in the United States.

We also promote our tests and services through marketing channels commonly used by the biopharma and pharmaceutical industries, such as internet, medical meetings and broad-based publication of our scientific and economic data. In addition, we provide easy-to-access information to our customers over the internet through dedicated websites. Our customers value easily accessible information in order to quickly review patient or study information.

Research and Development Collaborations

We formally and informally collaborate with leading oncology centers and community-based hospitals to develop our proprietary diagnostic tests, and we work closely with leading cancer researchers at these institutions to develop proprietary tests tailored to their needs and specifications. Additionally, many of these centers have obtained Specialized Programs of Research Excellence status, as designated by the National Cancer Institute. Our collaborations with these centers give us access to large datasets of information that we use to develop our proprietary tests.

Scientific and Clinical Advisory Boards

We have two advisory boards to counsel our scientific and clinical direction. Our Scientific Advisory Board is comprised of preeminent scientists and physicians from the fields of cancer biology, cancer pathology, cancer medicine and molecular genetics. We have scientists and clinicians from leading cancer centers, including Memorial Sloan-Kettering Cancer Center, Mt. Sinai and the Institute for Cancer Genetics at Columbia University. These distinguished scientists and clinicians help oversee and review the scientific innovation, integrity and clinical relevancy of our program. The board of directors appoints members to the Scientific Advisory Board. Our Clinical Advisory Board is comprised of preeminent clinicians and scientists focused on clinical implementation of our proprietary tests and services and mapping those tests and services to patient needs.

Competition

As a developer and provider of genomic-based tests and services that provide personalized diagnostic, prognostic and theranostic information for hematological, and other cancers, we rely extensively on our ability to combine research insights with high-quality, state-of-the art clinical laboratory testing. We believe that we compete principally on the basis of:

• our ability to address complex cancers that are currently difficult to prognose and challenging to predict treatment outcomes using currently available technologies;

• the ability of our proprietary tests and services to provide more information than existing tests with respect to the cancers we address;

• our ability to utilize a wide variety of sample types, accelerating the time-frame for clinical validation of our tests and allowing health care providers to readily integrate our tests into their established workflow;

• our ability to perform clinical studies using FFPE samples to either validate or develop novel insights for our proprietary programs;

• the quality of our services and our ability to collaborate with our customers on a consultative basis;

• our research and clinical collaborations with key academic and clinical study groups;

• the quality and global reach of our clinical reference laboratories, which enables consistent, comprehensive and reproducible results;

• the level of disease specific knowledge and customer service we provide, both to academic centers and community based health care professionals; and

We believe that we compete favorably with respect to these factors, although we cannot provide assurances that we will be able to continue to do so in the future or that new products or tests that perform better than our proprietary tests and services will be introduced. We believe that our continued success depends on our ability to:

•expand and enhance our proprietary tests to provide clinically meaningful information in additional indications;

•continue to innovate and maintain scientifically advanced technology;

•successfully market and sell our proprietary tests in the United States;

•continue to obtain appropriate regulatory approvals in the United States and abroad;

•continue to validate our pipeline of genomic tests and proprietary services;

•continue to obtain positive reimbursement decisions from payors and from CMS;

•maintain existing and enter into new research and clinical collaborations with key academic and clinical study groups;

• continue to enter into partnerships with local distributors and/or manufacturers to expand into emerging markets, including Mexico and Brazil;

•continue to attract and retain skilled scientific and clinical personnel;

•obtain and maintain our clinical reference laboratory accreditations and licenses; and

•obtain patents or other protection for our proprietary tests and services.

Our principal competition comes from existing mainstream diagnostic methods and laboratories that pathologists and oncologists use and have used for many years or decades. It may be difficult to change the methods or behavior of the referring pathologists and oncologists to incorporate our molecular diagnostic testing in their practices. In addition, companies offering capital equipment and kits or reagents to local pathology laboratories represent another source of potential competition. These kits are used directly by the pathologist, which can facilitate adoption.

We also face competition from companies that offer products or have conducted research to profile genes, gene expression or protein biomarkers in various cancers. In particular, Quest Diagnostics market arrays which are competitive to our MatBA®-CLL and MatBA®-SLL arrays, and both Foundation Medicine and LabCorp offer NGS based tests and panels for oncology. Personalized genetic diagnostics is a new area of science, and we cannot predict what tests others will develop that may

21

compete with or provide results superior to the results we are able to achieve with the tests we develop. Our competitors include public companies such as: NeoGenomics, Inc., Quest Diagnostics, Abbott Laboratories, Inc., Johnson & Johnson, Roche Molecular Systems, Inc., bioTheranostics, Inc. (part of the bioMérieux S.A.), Genomic Health, Inc., LabCorp, Inc., Myriad Genetics, Inc., Qiagen N.V., Response Genetics, Inc., Rosetta Genomics Ltd., and Foundation Medicine, Inc., and many private companies. We expect that pharmaceutical and biopharmaceutical companies will increasingly focus attention and resources on the personalized diagnostic sector as the potential and prevalence increases of molecularly targeted oncology therapies approved by FDA along with companion diagnostics. For example, FDA has recently approved two such agents- Xalkori crizotinib from Pfizer Inc. along with its companion anaplastic lymphoma kinase FISH test from Abbott Laboratories, Inc. and Zelboraf vemurafenib from Genentech USA Incorporated and Daiichi-Sankyo Inc. along with its companion B-RAF kinase V600 mutation test from Roche Molecular Systems, Inc. These two recent FDA approvals are only the second and third instances ever of simultaneous approvals of a drug and companion diagnostic, the first being the 1998 approval of Genentech, Inc.’s Herceptin trastuzumab for HER2 positive breast cancer along with the HercepTest from partner Dako A/S. Our competitors may invent and commercialize technology platforms or tests that compete with ours.

Additionally, projects related to cancer genomics have received increased government funding, both in the United States and internationally. As more information regarding cancer genomics becomes available to the public, we anticipate that more products aimed at identifying targeted treatment options will be developed and that these products may compete with ours. In addition, competitors may develop their own versions of our tests in countries where we did not apply for patents or where our patents have not issued and compete with us in those countries, including encouraging the use of their test by physicians or patients in other countries.

Third-Party Suppliers and Manufacturers

We maintain control, validation and quality assurance over our NGS panels, DNA microarrays and probes. Our microarrays are designed in our facility by our scientists and technicians using state of the art genomic mapping and analysis software. The specifications are sent to Agilent for final manufacturing. Agilent manufactures our microarrays under strict quality control and compliance with ISO 9001 and ISO 13485 at its Santa Clara, California facility. Agilent also has another manufacturing facility in Europe that can be made available for microarray printing. Upon manufacturing our custom, proprietary microarrays, Agilent ships them back to our Rutherford facility for testing and acceptance.

The DNA component of our DNA FISH probes is produced under strict adherence to regulatory procedures in our Rutherford facility and also at a third party facility depending on demand and workflow. The DNA is shipped for final manufacture to our partner in India. In February 2012 we entered in to an agreement with Kamineni Life Sciences to supply outsourced manufacturing for the production of our DNA FISH probes. The manufacturing operations became fully operational in India in the fourth quarter of 2012 and several batches of DNA FISH probes have been successfully manufactured. We control overall quality and process management and the final quality assurance in a manner that is CE compliant and adheres to our Quality Management System.

We work with electronic medical records providers to facilitate seamless communication between our laboratory and the oncologist or pathologist at the test ordering site. Currently, we have the ability to integrate with electronic medical record systems, as we have already done with MDL, an electronic medical record provider. We do this integration through utilizing HL7 interfaces, which are standard in health care information technology systems. We currently employ HL7 for its integration with a revenue cycle management company, XiFin, as well as with its electronic medical records partners such as MDL. The use of the HL7 interface allows systems written in different languages and running on different platforms to be able to talk to each other through the use of an abstracted data layer. This means that we do not have to spend significant extra time, often months, designing and developing common communications protocols when integrating with other electronic

23

health records systems or billing systems providers.

When a customer takes a specimen from a patient for diagnostic testing, he or she will complete a requisition form (either by hand or electronically, or via electronic medical records technology), and package the specimen for shipment to us. Once we receive the specimen at our laboratory and we enter all pertinent information about the specimen into our clinical laboratory information system, one of our histotechnologists, cytotechnologists, flow technologists or molecular technologists prepares the specimen for diagnosis. The prepared specimen is sent to one of our pathologists or directors who is experienced in making the diagnosis requested by the referring oncologist or pathologist.

After diagnosis, our pathologist uses our laboratory information systems to prepare a comprehensive report, which includes any relevant images associated with the specimen. Our clinical reporting portal, cgireports.com, allows a referring oncologist or pathologist to access his/her test results in real time in a secure HIPAA compliant manner. The reports are generated in industry standard PDF formats which allows for high definition color images to be reproduced clearly. This portal has been fully operational at our facilities since 2011.

In most cases we provide both the technical analysis and professional diagnosis, although we also fulfill requests from oncologists and pathologists for only one service or the other. If an oncologist or pathologist at the hospital, cancer center, reference laboratory or physician office requires only the analysis, we prepare the data and then return it to the referring oncologist or pathologist for assessment and diagnosis.

Quality Assurance

We are committed to providing reliable and accurate diagnostic services to our customers. Accurate specimen identification, timely communication of diagnoses, and prompt correction of errors, is critical. We monitor and improve our performance through a variety of methods, including performance improvement indicators, proficiency testing (CAP and New York State), external audits and satisfaction surveys. All quality concerns and incidents are subject to root cause analysis and our procedures are put through annual evaluation to ensure that we are providing the best services possible to our patients and customers. Protection of patient results from misuse and improper access is imperative and thus electronic and paper results are guarded via password- protection and identification cards.

We have established a comprehensive Quality Assurance and Management Program for our laboratory designed to drive accurate and timely test results and to ensure the consistent high quality of our testing services. The Quality Assurance and Management Program documents the quality assurance/performance improvement plans and policies and the laboratory quality assurance and quality control procedures that are necessary to ensure that we offer the highest quality of diagnostic testing services. This program is designed to satisfy all the requirements necessary for local and state licensures by the New Jersey Health Department and the New York Department of Health Clinical Laboratory Evaluation Program and accreditation for clinical diagnostic laboratories by CAP. We follow the policies and procedures for patient and employee safety, hazardous waste disposal and fire codes stated in the general laboratory procedure manual. We believe that all pertinent regulations of CLIA, Occupational Safety and Health Administration (“OSHA”), Environmental Protection Agency and FDA are satisfied by following the established guidelines and procedures of our Quality Assurance and Management Program.

In addition to the compulsory proficiency programs and external inspections required by CMS and other regulatory agencies, we have developed a variety of internal systems and procedures to emphasize, monitor and continuously improve the quality of our operations. We maintain internal quality controls by routinely processing specimens with known diagnoses in parallel with patient specimens. We also have an extensive, internally administered program of specimen proficiency testing, in which our laboratory staff are blinded to the results.

We participate in numerous externally administered quality surveillance programs and our laboratory is accredited by CAP. The CAP accreditation program involves both unannounced on-site inspections of our laboratories and our participation in CAP’s ongoing proficiency testing program. CAP is an independent, non- governmental organization of board-certified pathologists that accredits laboratories nationwide on a voluntary basis and that has been recognized by CMS as an accreditation organization to inspect laboratories to determine adherence to the CLIA standards. Successful participation in CAP’s proficiency testing program satisfies the CLIA requirement for participation in proficiency testing programs administered by an external source.

Each of our facilities maintains its own quality assurance processes, which are coordinated across sites to maintain consistency in standard operating procedures, employee training and safety manuals.

Third-party Payor Reimbursement

Depending on the billing arrangement and applicable law, we are reimbursed for clinical services by:

• third-party payors that provide coverage to the patient, such as an insurance company, managed care organization or a governmental payor program;

• physicians or other authorized parties (such as hospitals or independent laboratories) that order the testing service or otherwise refer the services to us; or

• the patient.

For the year ended December 31, 2014, we derived approximately 16% of our total revenue from private insurance, including managed care organizations and other health care insurance providers, 11% from Medicare, and 16% from other health care facilities, including hospitals.

Where there is a coverage policy, contract or agreement in place, we bill the third-party payor, the hospital or referring laboratory as well as the patient (for deductibles and coinsurance or copayments, where applicable) in accordance with the policy or contractual terms. Where there is no coverage policy, contract or agreement in place, we pursue reimbursement on behalf of each patient on a case-by-case basis and rely on applicable billing standards to guide our claims. In addition, we have implemented a new patient financial assistance program (CGI MAP Program) that complies with Federal guidelines.

We are reimbursed for three categories of tests: (1) genetic and molecular testing; (2) anatomic pathology and IHC and (3) general immunology and flow cytometry. Reimbursement under the Medicare program for the diagnostic services that we offer is based on either the Medicare Physician Fee Schedule or Medicare Clinical Laboratory Fee Schedule, each of which in turn is subject to geographic adjustments and is updated annually. Medical services provided to Medicare beneficiaries that require a degree of physician supervision or other involvement, such as pathology tests, are generally reimbursed under the Medicare Physician Fee Schedule, whereas clinical diagnostic laboratory tests are generally reimbursed under the Clinical Laboratory Fee Schedule. Most of the services that we provide are for genetic and molecular testing, which are reimbursed as clinical diagnostic laboratory tests.

Medicare fee schedule amounts are established for each billing code, or CPT code. In addition, for its laboratory fee schedule, Medicare also sets a cap on the amount that it will pay for any individual test. This cap, usually referred to as the National Limitation Amount, is set at a percentage of the median of all the contractor fee schedule amounts for each billing code. In the past, Congress has lowered the percentage of the median used to calculate the National Limitation Amount in order to achieve budget savings. Currently, the National Limitation Amount ceiling is set at 74% of the median for established tests and 100% of the median for certain new tests that were not previously reimbursed. In billing Medicare for clinical laboratory services, we are required to accept, as payment in full, the lowest of our actual charge, the fee schedule amount for the state or local geographical area or the National Limitation Amount. There is currently no copayment or deductible required for tests paid under the CLFS, although Congress periodically has considered implementing such a requirement.

In addition, Congress routinely lowers or eliminates the update factor that would otherwise apply to the applicable clinical laboratory fee schedule (CLFS) payment. For example, under the health care reform legislation, passed in 200-, payments under the CLFS are reduced by 1.75% through 2015 and, in addition, a productivity adjustment, further reducing payment rates is also imposed. In addition, in February 2012, Congress passed the Middle Class Tax Relief and Job Creation Act of 2012, which required that the CLFS be “rebased” by -2%. As a result of these changes, for 2015 the CLFS was reduced by -.25%.

Further, in 2014, Congress passed the Protecting Access to Medicare Act or PAMA which also makes significant changes in the way the Medicare will pay for laboratory services. Under PAMA, laboratories will be required to report the amount that they are paid by third party payors for each test beginning in January 2016. CMS will use this data to calculate a weighted median for each test. That new price will become effective on January 1, 2017, although any resulting reductions will be phased in over time. This data reporting process will be repeated every three years for most tests, although Advanced Diagnostic Laboratory Tests (ADLTs) will have to be reported every year. It is possible that some of our tests could be considered ADLTs, which will require us to report prices annually. In addition, we may also be required to obtain a code from CMS or an entity that it designates for our tests that have not previously had a code. It is not known at this time how these changes will affect our reimbursement.

Certain of our tests are paid under the Physician Fee Schedule, rather than the CLFS. Tests paid for under the PFS are based on “relative value units” established for each service. These RVUs are then multiplied by a conversion factor to arrive at a monetary amount. Each year, CMS calculates an update to this conversion factor based on a formula included in the Medicare law, referred to as the Sustainable Growth Rate (SGR) Formula. When it is applied, this SGR formula often would require a decrease in reimbursement unless Congress acts to overturn this result. As a result, Congress consistently passes legislation to

25

prevent implementation of significant cuts that would otherwise be effective. . For 2014, CMS had projected the reimbursement cut resulting from the SGR formula would be approximately 20 percent, unless Congress acted to prevent the reduction. On December 18, 2013, Congress passed legislation that enacted a 0.5 percent increase in the conversion factor, which was effective until March 31, 2014. On April 1, 2014, President Obama signed the Protecting Access to Medicare Act of 2014, or PAMA. PAMA extended the 0.5 percent increase through March 31, 2015 and made other changes to laboratory reimbursement discussed below. Currently, Congress is considering an extension of the increase enacted by PAMA. If Congress fails to act before March 31, 2015, or if it does not enact a long-term change to the SGR, then future decreases in the Medicare physician schedule are possible.

Medicare also has policies that may limit when we can bill directly for our services and when we must instead bill another provider, such as a hospital. When the testing that we perform is done on a specimen that was collected while the patient was in the hospital, as either an inpatient or outpatient, we may be required to bill the hospital for our services, rather than the Medicare program, depending on whether or not the service was ordered more than 14 days after the patient’s discharge from the hospital. These requirements are complex and time- consuming and, depending on what they require, may affect our ability to collect for our services.

Our reimbursement rates can vary based on whether we are considered to be an “in-network” provider, a participating provider, a covered provider or an “out-of-network” provider. These definitions can vary from insurance company to insurance company, but we are generally considered an “out of network” or non- participating provider in the vast majority of our cases. It is not unusual for a company that offers highly specialized or unique testing to be an “out of network” provider. An “in-network” provider usually has a contracted arrangement with the insurance company or benefits provider. This contract governs, among other things, service-level agreements and reimbursement rates. In certain instances an insurance company may negotiate an “in-network” rate for our testing rather than pay the typical “out-of-network” rate. An “in-network” provider usually has rates that are lower per test than those that are “out-of-network”, and that rate is based on the laboratory fee schedule. The discount rate varies based on the insurance company, the testing type and the often times the specifics of the patient’s insurance plan.

In May 2013 we entered into an agreement with Multiplan, Inc., a leading provider of healthcare cost management solutions, which we believe will help us improve reimbursement rates and shorten our collection times. We intend to seek similar arrangements with other health cost care managers and insurance companies.

In addition, as part of the Middle Class Tax Relief and Job Creation Act of 2012 (“MCTRJCA”), signed into law by the President on February 22, 2012, Congress eliminated the special billing rule that had allowed laboratories to bill Medicare for the technical component of certain pathology services furnished to patients of qualifying hospitals. Effective July 1, 2012, independent laboratories, like our laboratory, are required to bill the hospital, rather than the Medicare Program, for the technical component of these services in most instances.

Billing Codes for Third-party Payor Reimbursement

CPT codes are the main data code set used by physicians, hospitals, laboratories and other health care professionals to report separately-payable clinical laboratory tests for reimbursement purposes. The CPT coding system is maintained and updated on an annual basis by the American Medical Association. Although there is no specific code to report microarrays for oncology, such as our MatBA®-CLL, there are existing codes that describe all of the steps in our MatBA®-CLL testing process. We currently use a combination of different codes to describe the various steps in our testing process. Many of the CPT codes used to bill for molecular pathology tests such as ours have been significantly revised by the CPT Code Editorial Panel. These new codes replace the more general “stacking” codes that were previously used to bill for these services with more test-specific codes, which became effective January 2013. In the Final Physician Fee Schedule Rule, which was issued in November 2012, CMS stated that it had determined it would pay for the new codes as clinical laboratory tests, which are payable on the Clinical Laboratory Fee Schedule (CLFS). CMS also stated that it planned to “gapfill” the new codes; that is, it will ask the contractors to determine a reasonable price for the new codes. This process was completed in 2013, and these tests are now paid for under the new "gapfilled" rates.

Among the new codes that were created by CPT were a specific subset of codes called Multi-analyte Assays with Algorithmic Analysis (MAAAs). These tests typically use an algorithm applied to certain specific components to arrive at a score that is used to predict a particular clinical outcome. CMS recently stated that it will not issue a categorical determination for all MAAA tests, but will consider each individual test that is classified by the CPT as a MAAA on its own merits. Currently less than 10% of our revenue is derived from tests that may be considered MAAAs.

As of January 1, 2014 we are utilizing the “Not Otherwise Classified” (NOC) codes when billing for some of our MAAA

26

tests. The reimbursement policies for the NOC codes vary from payor to payor with regard to specific tests and many of the payors have followed suit. This extends our revenue cycle for these particular tests, where the normal timeframe for reimbursement of a claim is approximately 45-90 days. These tests can take upwards of a year to be reimbursed. There can be no guarantees that Medicare and other payors will establish positive or adequate coverage policies or reimbursement rates in the future. We are moving forward with plans to obtain billing codes for our tests. A specific code for our tests, however, does not assure an adequate coverage policy or reimbursement rate. Please see the section entitled “Legislative and Regulatory Changes Impacting Clinical Laboratory Tests” for further discussion of certain legislative and regulatory changes to these billing codes and the impact on our business.

Coverage and Reimbursement for Our Proprietary Tests

Although MatBA® is a relatively new test, some third-party payors have established coverage and reimbursement policies set for other microarray-based tests. We have been able to receive reimbursement for our tests from some payors based on their established policies, including major commercial third-party payors.

The current landscape with payors is generally as follows:

Commercial Third-party Payors and Patient Pay. Where there is a coverage policy in place, we bill the payor and the patient in accordance with the established policy. Where there is no coverage policy in place, we pursue reimbursement on behalf of each patient on a case-by-case basis. Our efforts in obtaining reimbursement based on individual claims, including pursuing appeals or reconsiderations of claims denials, take a substantial amount of time, and bills may not be paid for many months, if at all. Furthermore, if a third-party payor denies coverage after final appeal, payment may not be received at all. We are working to decrease risks of nonpayment by implementing a revenue cycle management system. Third party payors are still establishing payment policies for panel-based tests.

Medicare and Medicaid. We believe that as much as 30% to 40% of our future market for our tests may be derived from patients covered by Medicare and Medicaid.

We cannot predict whether, or under what circumstances, payors will reimburse our proprietary tests. Payment amounts can also vary across individual policies. Denial of coverage by payors, or reimbursement at inadequate levels, would have a material adverse impact on market acceptance of our tests.

Legislative and Regulatory Changes Impacting Clinical Laboratory Tests

From time to time, Congress has revised the Medicare statute and the formulas it establishes for both the Medicare Clinical Laboratory Fee Schedule and the Physician Fee Schedule. The payment amounts under the Medicare fee schedules are important not only for our reimbursement under Medicare, but also because the schedule often is used as a basis for establishing the payment amounts set by other third party payors. For example, state Medicaid programs are prohibited from paying more than the Medicare fee schedule limit for clinical laboratory services furnished to Medicaid recipients.

Under the statutory formula for clinical laboratory fee schedule amounts, increases are made annually based on the Consumer Price Index for All Urban Consumers as of June 30 for the previous twelve-month period. From 2004 through 2008, Congress eliminated the Consumer Price Index for All Urban Consumers update in the Medicare Prescription Drug, Improvement and Modernization Act of 2003. In addition, for years 2009 through 2013, the Medicare Improvements for Patients and Providers Act of 2008 (“MIPPA”) mandated a 0.5% cut to the Consumer Price Index for All Urban Consumers. Accordingly, the update for 2009 was reduced to 4.5% and negative 1.9% for 2010. In March 2010, the President signed into law PPACA, which, among other things, imposed additional cuts to the Medicare reimbursement for clinical laboratories. The PPACA replaced the 0.5% cut enacted by MIPPA with a “productivity adjustment” that will reduce the Consumer Price Index update in payments for clinical laboratory tests. In 2011, the productivity adjustment was -1.2%. In addition, the PPACA includes a separate 1.75% reduction in the CPI update for clinical laboratories for the years 2011 through 2015. On February 22, 2012, President Obama signed the MCTRJCA, which mandated an additional change in reimbursement for clinical laboratory services payments. This legislation requires CMS to reduce the Medicare clinical laboratory fee schedule by 2% in 2013, which in turn will serve as a base for 2014 and subsequent years. Based on the changes required by PPACA and MCTRJCA, payment for clinical laboratory services will be reduced by approximately 0.25% for 2015.

With respect to our diagnostic services for which we are reimbursed under the Medicare Physician Fee Schedule, because of the statutory formula, the “Sustainable Growth Rate” (SGR), the rates would have decreased for the past several years if Congress failed to intervene. In the past, when the application of the statutory formula resulted in lower payment, Congress has passed interim legislation to prevent the reductions. On November 1, 2012, the Centers for Medicare & Medicaid Services

27

(CMS) issued its 2013 Physician Fee Schedule Final Rule (the “Final Rule”). In the Final Rule, CMS called for a reduction of approximately 26.5% in the 2013 conversion factor that is used to calculate physician reimbursement. However, the American Taxpayer Relief Act of 2012, which was signed into law on January 2, 2013, prevented this proposed reduction and kept the existing reimbursement rate in effect until December 31, 2013.

For 2014, CMS projected the cut would be about 24%, unless Congress acted. However, on December 18, 2013, Congress passed legislation that enacted a 0.5% update in the conversion factor, which will be effective until March 31, 2014. Currently, Congress is considering a long-term fix to the SGR, which could eliminate the need for annual Congressional action. On April 1, 2014, President Obama signed the Protecting Access to Medicare Act of 2014, or PAMA. PAMA extended the 0.5 percent increase through March 31, 2015 and made other changes to laboratory reimbursement discussed below. Currently, Congress is considering an extension of the increase enacted by PAMA. If Congress fails to act before March 31, 2015, or if it does not enact a long-term change to the SGR, then future decreases in the Medicare physician schedule are possible.

In addition to the reductions described above, our Medicare payments under both the CLFS and the PFS are also subject to an additional 2% reduction, as a result of “sequestration.” This automatic cut results because the Joint Select Committee on Deficit Reduction, which was created by congress in 2011, was unable to agree on a set of deficit reduction recommendations for Congress to vote on. The reduction is scheduled to continue until 2024.

For the year ended December 31, 2014 and the year ended December 31, 2013, approximately 11% and 13%, respectively, of our total revenues are derived from Medicare generally and any changes to the physician fee schedule that result in a decrease in payment could adversely impact our revenues and results of operations.

In addition, periodically CMS also changes its payment policies related to laboratory reimbursement in ways that could have an impact on the revenues of the Company. For example, in 2013 Final Rule, CMS included a reduction of certain relative value units and geographic adjustment factors used to determine reimbursement for a number of commonly used pathology codes, including CPTs 88300, 88302, 88304, and 88305. In particular, the 2013 Final Rule implemented a cut of approximately 33% in the global billing code for 88305 and a 52% cut in the Technical Component of that code. These codes describe services that we must perform in connection with our tests and we bill for these codes in connection with the services that we provide. In the 2013 Final Rule, CMS also announced how it intended to set prices for the new molecular diagnostic tests, for which the American Medical Association had adopted over 100 new codes. In that Rule, CMS announced it intended to continue to pay for the new molecular codes on the CLFS rather than move them to the Physician Fee Schedule, as some stakeholders had urged. It would then request that the Medicare Administrative Contractors “gapfill” the new codes and set an appropriate price for them. That “gapfilling” process took place over 2013 and CMS announced the new prices for these codes in September, 2013. The median of the prices set by the contractors will become the new prices for these codes, effective January 1, 2014. We do not yet know what impact, if any, these changes will have on the Company’s operations.

In the Proposed Physician Fee Schedule Rule for 2014, issued on July 8, 2013, CMS made two proposals that could affect laboratory reimbursement. First, CMS made a proposal to change how it calculates the RVUs used to calculate payments under the PFS. Under this proposal, where a service was paid at a lower rate in the hospital based on the hospital Outpatient Prospective Payment System (OPPS) than it is under the PFS, CMS proposed to reduce the RVUs for that service in order to equalize the payment between the two systems. This change, if implemented, would have resulted in approximately a 25% cut in aggregate payments to independent laboratories. In the Final Physician Rule for 2014, however, CMS chose not to implement this proposal, although it stated that it would develop a revised proposal that it would propose in the future. At this point, it is impossible to know what the impact of such a proposal might be on the Company.

In addition, in the 2014 Proposed Rule, CMS also noted that payments for many codes paid under the Clinical Laboratory Fee Schedule have not been revised to reflect technological advances that have occurred since the CLFS was first developed in 1984. CMS therefore proposed that it would begin to review all codes on the CLFS and adjust them to reflect technological changes, a process that it expected would take about five years. However, in April of 2014, Congress passed the Protecting Access to Medicare Act, which eliminated CMS’s authority to implement its plan to adjust payments based on technological advances. CMS has since stated it will not implement this proposal.

In PAMA, Congress also changed the way the Medicare will pay for clinical laboratory services. Under PAMA, laboratories will be required to report the amount that they are paid by third party payors for each test beginning in January 2016. CMS will use this data to calculate a weighted median for each test. That new price will become effective on January 1, 2017, although any resulting reductions will be phased in over time. This data reporting process will be repeated every three years for most tests, although Advanced Diagnostic Laboratory Tests (“ADLTs”) will have to report every year. It is possible that some of our tests could be considered ADLTs, which will require us to report prices annually. In addition, we may also be required to obtain

28

a code from CMS or an entity that it designates for our tests that have not previously had a code. It is not known at this time how these changes will affect our reimbursement.

In addition, CMS made several other changes in the 2014 Final Rule that could impact our business. First, CMS implemented a policy that will bundle payment for the examination of 10 or more prostate biopsies for an individual patient, rather than paying separately for each individual procedure as had been done previously. This will result in a significant reduction in reimbursement on each of these procedures. In addition, CMS also has developed new codes applicable to billing for Immunohistochemistry procedures, which are a common staining procedure used in pathology. Those codes will reduce the reimbursement that we will receive when we provide these services. Finally, CMS has also implemented a set of edits under its National Correct Coding Initiative, which will only pay for a single unit of service when we perform a FISH (Fluorescent In Situ Hybridization) test. As many FISH tests require two or more probes, this change will also reduce the reimbursement received by the Company. We are still reviewing the provisions to determine the impact of these changes.

Further, with respect to the Medicare Program, Congress has proposed on several occasions to impose a 20% coinsurance on patients for clinical laboratory tests reimbursed under the clinical laboratory fee schedule, which would require us to bill patients for these amounts. Because of the relatively low reimbursement for many clinical laboratory tests, in the event that Congress were to ever enact such legislation, the cost of billing and collecting for these services would often exceed the amount actually received from the patient and effectively increase our costs of billing and collecting.

Finally, some of our Medicare claims may be subject to policies issued by Palmetto GBA, the current Medicare Administrative Contractor for North Carolina, South Carolina, Virginia and West Virginia. The Medicare contractor has recently issued a Local Coverage Decision that affects coverage, coding and billing of many molecular diagnostic tests. Under this Local Coverage Determination, Palmetto will not cover any molecular diagnostic tests, including our tests, unless the test is expressly included in a National Coverage Determination issued by CMS or a Local Coverage Determination or coverage article issued by Palmetto. Currently, laboratory providers may submit coverage determination requests to Palmetto for consideration and apply for a unique billing code for each test (which is a separate process from the coverage determination). In the event that a non-coverage determination is issued, the laboratory must wait six months following the determination to submit a new request. In addition, effective May 1, 2012, Palmetto implemented its new Molecular Diagnostic Services Program, under which, among other things, laboratories must use newly-assigned billing codes specific to the test. These new billing codes enable Palmetto to measure utilization and apply coverage determinations. Denial of coverage by Palmetto, or reimbursement at inadequate levels, would have a material adverse impact on market acceptance of our tests. Other Medicare contractors are also following the policies adopted by Palmetto.

Governmental Regulations

Clinical Laboratory Improvement Amendments of 1988 and State Regulation

As a diagnostic service provider, we are required to hold certain federal, state and local licenses, certifications and permits to conduct our business. As to federal certifications, in 1988, Congress passed the Clinical Laboratory Improvement Amendments (“CLIA”) establishing quality standards for all laboratories testing to ensure the accuracy, reliability and timeliness of patient test results regardless of where the test was performed. The Company’s laboratory is CLIA accredited. As to state laws, we are required to meet certain laboratory licensing and other requirements. Our laboratory holds the required licenses and accreditations obtained from the applicable state agencies in which we operate. For more information on state licensing requirements, see the sections entitled “Description of the Business-Government Regulations-New Jersey and New York State Laboratory Licensing” and “Description of the Business-Government Regulations-Other States’ Laboratory Testing”. Under CLIA, a laboratory is defined as any facility which performs laboratory testing on specimens derived from humans for the purpose of providing information for the diagnosis, prevention or treatment of disease, or the impairment of, or assessment of health. CLIA also requires that we hold a certificate applicable to the type of work we perform and comply with certain standards. CLIA further regulates virtually all clinical laboratories by requiring they be accredited by the federal government and comply with various operational, personnel, facilities administration, quality and proficiency requirements intended to ensure that their clinical laboratory testing services are accurate, reliable and timely. CLIA compliance and accreditation is also a prerequisite to be eligible to bill for services provided to governmental payor program beneficiaries. CLIA is user-fee funded. Therefore, all costs of administering the program must be covered by the regulated facilities, including certification and survey costs.

We are subject to survey and inspection every two years to assess compliance with program standards, and may be subject to additional unannounced inspections. Laboratories performing high complexity testing are required to meet more stringent requirements than laboratories performing less complex tests. In addition, a laboratory like ours that is certified as “high complexity” under CLIA may obtain analyte specific reagents, which are used as the basis for diagnostic tests that are developed and validated for use in examinations the laboratory performs itself known as laboratory-developed tests (“LDTs”).

29

Our laboratory is CLIA accredited and under our CLIA accreditation, we were allowed to first use MatBA®-CLL in November 2010 and MatBA®-SLL in the first quarter 2012.

In addition to CLIA requirements, we participate in the oversight program of the College of American Pathologists (“CAP”). Under CMS requirements, accreditation by CAP is sufficient to satisfy the requirements of CLIA. Therefore, because we are accredited by CAP, we are deemed to also comply with CLIA. CLIA also provides that a state may adopt laboratory regulations that are more stringent than those under federal law, and a number of states have implemented their own more stringent laboratory regulatory schemes. State laws may require that laboratory personnel meet certain qualifications, specify certain quality controls, or prescribe record maintenance requirements.

FDA

The U.S. Food and Drug Administration (“FDA”) regulates the sale or distribution, in interstate commerce, of medical devices under the Federal Food, Drug, and Cosmetic Act (“FDCA”), including in vitro diagnostic test kits, reagents and instruments used to perform diagnostic testing. Such devices must undergo pre-market review by FDA prior to commercialization unless the device is of a type exempted from such review by statute or pursuant to FDA’s exercise of enforcement discretion. FDA, to date, has not exercised its authority to actively regulate the development and use of LDTs such as ours as medical devices and therefore we do not believe that our LDTs currently require pre-market clearance or approval.

Section 1143 of the Food and Drug Administration Safety and Innovation Act, signed by the President on July 9, 2012, requires FDA to notify Congress at least 60 days prior to issuing a draft or final guidance regulating LDTS and provide details of the anticipated action. On July 31, 2014, FDA notified Congress pursuant to the FDASIA that it intended to issue draft Guidances that would regulate LDTs. On October 3, 2014, the FDA issued two separate draft guidances: “Framework for Regulatory Oversight of Laboratory Developed Tests (LDTs)” (“The Framework Draft Guidance”) and “FDA Notification and Medical Device Reporting for Laboratory Developed Tests” (the “Notification Draft Guidance.”). In the Framework Draft Guidance, FDA states that after the Guidances are finalized, it will no longer exercise enforcement discretion with respect to most LDTs and will, instead, regulate them in a risk-based manner consistent with the existing classification of medical devices. Thus, the FDA plans to begin to enforce its medical device requirements, including premarket submission requirements, on LDTs that have historically been marketed without FDA premarket review and oversight. Comments on the Draft Guidances were due on February 2 and those comments are now being considered by the FDA. It is not known when the FDA may issue final Guidances or what form those Guidances may take.

The Framework Draft Guidance states that within six months after the Guidances are finalized, all laboratories will be required to give notice to the FDA and provide basic information concerning the nature of the LDTs offered. The FDA will then begin a phased review of the LDTs available, based on the risk associated with the test. For the highest risk LDTs, which the FDA classifies as Class III devices, the Framework Draft Guidance states that the FDA will begin to require premarket review within 12 months after the Guidance is finalized. Other high risk LDTs will be reviewed over the next four years and then lower risk tests, which will be classified as Class II, will be reviewed in the following four to nine years. The Framework Draft Guidance states that FDA expects to issue a separate Guidance describing the criteria for its risk-based classification 18-24 months after the Guidances are finalized.

If the FDA regulates LDTs as proposed, then it would classify LDTs according to the current system used to regulate medical devices. Under that system, there are three different classes of medical devices, with the requirements becoming more stringent depending on the Class. Class I devices are those for which reasonable assurance of the safety and effectiveness can be provided by adherence to FDA’s general regulatory controls for medical devices, which include compliance with the applicable portions of FDA’s Quality System Regulations, facility registration and product listing, reporting of adverse medical events and appropriate, truthful and non-misleading labeling, advertising and promotional materials, or general controls. Many Class I devices are exempt from pre-market regulation, however, some Class I devices require pre-market clearance by FDA through the 510(k) pre-market notification process described below.

Class II devices are subject to FDA’s general controls, and any other special controls as deemed necessary by FDA to provide reasonable assurance of the safety and effectiveness of the devices. Pre-market review and clearance by FDA for Class II devices are generally accomplished through the 510(k) pre-market notification procedure. Pre- market notification submissions are subject to user fees, unless a specific exemption applies. To obtain 510(k) clearance for a medical device (or for certain modifications to devices that have received 510(k) clearance), a manufacturer must submit a pre-market notification demonstrating that the proposed device is substantially equivalent to a previously cleared 510(k) device or to a pre-amendment device that was in commercial distribution before May 28, 1976 (a “predicate device”) for which FDA has not yet called for the submission of a pre-market approval (“PMA”) application. In making a determination that the device is substantially equivalent to a predicate device, FDA compares the proposed device to the predicate device or predicate devices

30

and assesses whether the subject device is comparable to the predicate device or predicate devices with respect to intended use, technology, design and other features which could affect the safety and effectiveness. If FDA determines that the subject device is substantially equivalent to the predicate device or predicate devices, the subject device may be cleared for marketing. FDA’s 510(k) clearance pathway generally takes from three to twelve months from the date the application is completed, but can take significantly longer. Moreover, in January 2011, FDA announced twenty-five specific action items it intended to take to improve transparency and predictability of the 510(k) program. We anticipate that the changes may also result in additional requirements with which manufacturers will need to comply in order to obtain or maintain 510(k) clearance for their devices. These additional requirements could increase the costs or time for manufacturers’ seeking marketing clearances through the 510(k) process. Moreover, the 510(k) process could result in a not-substantially equivalent determination, in which case the device would be regulated as a Class III device, discussed below, or could be eligible for de novo classification available for novel low and moderate risk devices. In the de novo process, FDA can classify a device into Class I or Class II based on a risk- based determination without the submission of a 510(k) or within 30 days after receipt of a not-substantially equivalent determination. In 2013, several assays and diagnostic tests received pre-market approval through the de novo process.

Class III devices are those devices which are deemed by FDA to pose the greatest risk, such as life-sustaining, life-supporting or implantable devices, have a new intended use, or use advanced technology that is not substantially equivalent to that of a legally marketed device. Reasonable assurance of the safety and effectiveness of Class III devices cannot be assured solely by the general controls and the other requirements described above. These devices are required to undergo the pre-market approval (“PMA”) process in which the manufacturer must demonstrate reasonable assurance of the safety and effectiveness of the device to FDA’s satisfaction. A PMA application must provide extensive preclinical and clinical trial data and also information about the device and its components regarding, among other things, device design, manufacturing and labeling. Premarket approval applications (and supplemental pre-market approval applications) are subject to significantly higher user fees than are 510(k) pre-market notifications. After approval of a PMA, a new PMA or PMA supplement is required in the event of a modification to the device, its labeling or its manufacturing process. The PMA process, including the gathering of clinical and nonclinical data and the submission to and review by FDA, can take several years.

A clinical trial may be required in support of a 510(k) submission and generally is required for a PMA application. These trials generally require an effective Investigational Device Exemption from FDA for a specified number of patients, unless the product is exempt from Investigational Device Exemption requirements or deemed a non-significant risk device eligible for more abbreviated Investigational Device Exemption requirements. The Investigational Device Exemption application must be supported by appropriate data, such as animal and laboratory testing results. Clinical trials may begin 30 days after the submission of the Investigational Device Exemption application unless FDA or the appropriate institutional review boards at the clinical trial sites place the trial on clinical hold.

Under the Guidances, LDTs would also be subject to significant post-market requirements as well. After a device is placed on the market, regardless of the classification or pre-market pathway, it remains subject to significant regulatory requirements. Even if regulatory approval or clearance of a medical device is granted, FDA may impose limitations or restrictions on the uses and indications for which the device may be labeled and promoted. Medical devices may be marketed only for the uses and indications for which they are cleared or approved.

Device manufacturers must also establish registration and device listings with FDA. A medical device manufacturer’s manufacturing processes and those of its suppliers are required to comply with the applicable portions of the Quality Systems Regulations, which cover the methods and documentation of the design, testing, production, processes, controls, quality assurance, labeling, packaging and shipping of medical devices. Domestic facility records and manufacturing processes are subject to periodic unscheduled inspections by FDA. FDA also may inspect foreign facilities that export products to the United States.

Failure to comply with applicable regulatory requirements can result in enforcement action by FDA, which may include any of the following sanctions: warning letters, fines, injunctions, civil or criminal penalties, recall or seizure of current or future products, operating restrictions, partial suspension or total shutdown of production, denial of 510(k) clearance or PMA applications for new products, or challenges to existing 510(k) clearances or PMA applications.

We are monitoring developments and anticipate that our products (CGH-Microarrays and FISH Probes) will be able to comply with requirements that are ultimately imposed by the FDA. In the meantime, we maintain our CLIA accreditation, which permits the use of LDTs for diagnostics purposes.

We believe that our LDTs and, should we reach that point, our in vitro diagnostic test kits, would likely be regulated as either Class II or Class III devices should FDA decide to proceed in the way that it has outlined in the Guidances. It is also possible

31

under those circumstances that some may fall into one Class and some into the other. Accordingly, some level of premarket review-either a 510(k), PMA or de novo approval-would likely be required for each test. While the data requirements are typically greater for Class III devices, the data required for Class II devices has increased, and it is likely that some amount of clinical data (retrospective or prospective or both) would be required for either type of submission. FDA continues to review the adequacy of its 510(k) process. It is difficult to predict what changes may result, but it should be assumed that any changes will increase, not decrease, the regulatory requirements.

In addition to the Draft Guidances discussed above, the FDA has taken other actions that could have an impact on our business. In 2013, FDA issued Final Guidance for industry regarding appropriate labeling and distribution practices for in vitro diagnostic products intended for research or investigational use only. FDA’s guidance cautions that labeling or distribution practices that conflict with research or investigational use (e.g., use in clinical diagnostic applications) could subject products shipped with research or investigational use labeling to all applicable requirements of the FDCA as well as enforcement action. As a result of FDA’s recent guidance, component suppliers for our LDTs may no longer be willing to distribute components to our clinical laboratory. If this were to occur, we could not produce our LDTs.

On August 6, 2014, the FDA also issued its Final Guidance on In Vitro Companion Diagnostic Devices. According to the Guidance, companion diagnostic devices are in vitro diagnostic devices that provide information that is essential for the safe and effective use of a corresponding therapeutic product. The Guidance notes that in most circumstances, FDA expects to approve or clear a companion diagnostic device and its corresponding therapeutic product contemporaneously, based on the label of the therapeutic product. If it were determined that our tests qualified as Diagnostic Devices then we might be required to file for either a 510(k) or a PMA, depending on the nature of the particular test.

Health Insurance Portability and Accountability Act, as amended by the Health Information Technology for Economic and Clinical Health Act (“HITECH”)

Under the administrative simplification provisions of HIPAA, as amended by HITECH, the United States Department of Health and Human Services has issued regulations which establish uniform standards governing the conduct of certain electronic health care transactions and protecting the privacy and security of Protected Health Information used or disclosed by health care providers and other covered entities. For further discussion of HIPAA and the impact on our business, see the section entitled “Risk Factors-Risks Related to Our Business-We are required to comply with laws governing the transmission, security and privacy of health information that require significant compliance costs, and any failure to comply with these laws could result in material criminal and civil penalties.”

Federal, State and Foreign Fraud and Abuse Laws

The federal Anti-Kickback Statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving remuneration to induce or in return for purchasing, leasing, ordering or arranging for the purchase, lease or order of any health care item or service reimbursable under a governmental payor program. The definition of “remuneration” has been broadly interpreted to include anything of value, including gifts, discounts, credit arrangements, payments of cash, waivers of co-payments, ownership interests and providing anything at less than its fair market value. Recognizing that the Anti-Kickback Statute is broad and may technically prohibit many innocuous or beneficial arrangements within the health care industry, the Department of Health and Human Services has issued a series of regulatory “safe harbors.” These safe harbor regulations set forth certain provisions, which, if met, will assure health care providers and other parties that they will not be prosecuted under the federal Anti- Kickback Statute. Although full compliance with these provisions ensures against prosecution under the federal Anti-Kickback Statute, the failure of a transaction or arrangement to fit within a specific safe harbor does not necessarily mean that the transaction or arrangement is illegal or that prosecution under the federal Anti-Kickback Statute will be pursued. For further discussion of the impact of federal and state health care fraud and abuse laws and regulations on our business, see the section entitled “Risk Factors-Risks Related to Our Business-We are subject to federal and state health care fraud and abuse laws and regulations and could face substantial penalties if we are unable to fully comply with such laws.”

In addition to the administrative simplification regulations discussed above, HIPAA also created two new federal crimes: health care fraud and false statements relating to health care matters. The health care fraud statute prohibits knowingly and willfully executing a scheme to defraud any health care benefit program, including private payors. A violation of this statute is a felony and may result in fines, imprisonment or exclusion from governmental payor programs such as the Medicare and Medicaid programs. The false statements statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for health care benefits, items or services. A violation of this statute is a felony and may result in fines, imprisonment or exclusion from governmental payor programs.

Finally, another development affecting the health care industry is the increased enforcement of the federal False Claims Act

32

and, in particular, actions brought pursuant to the False Claims Act’s “whistleblower” or “qui tam” provisions. The False Claims Act 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 by a federal governmental payor program. The qui tam provisions of the False Claims Act allow a private individual to bring actions on behalf of the federal government alleging that the defendant has defrauded the federal government by submitting a false claim to the federal government and permit such individuals to share in any amounts paid by the entity to the government in fines or settlement. In addition, various states have enacted false claim laws analogous to the federal False Claims Act, although many of these state laws apply where a claim is submitted to any third-party payor and not merely a governmental payor program. When an entity is determined to have violated the False Claims Act, it may be required to pay up to three times the actual damages sustained by the government, plus civil penalties ranging from $5,500 to $11,000 for each false claim.

Additionally, in Europe various countries have adopted anti-bribery laws providing for severe consequences, in the form of criminal penalties and/or significant fines, for individuals and/or companies committing a bribery offence. Violations of these anti-bribery laws, or allegations of such violations, could have a negative impact on our business, results of operations and reputation. For instance, in the United Kingdom, under the new Bribery Act 2010, which went into effect in July 2011, a bribery occurs when a person offers, gives or promises to give a financial or other advantage to induce or reward another individual to improperly perform certain functions or activities, including any function of a public nature. Bribery of foreign public officials also falls within the scope of the Bribery Act 2010. Under the new regime, an individual found in violation of the Bribery Act of 2010, faces imprisonment of up to 10 years. In addition, the individual can be subject to an unlimited fine, as can commercial organizations for failure to prevent bribery.

Physician Referral Prohibitions

Under a federal law directed at “self-referral,” commonly known as the “Stark Law,” there are prohibitions, with certain exceptions, on Medicare and Medicaid payments for laboratory tests referred by physicians who personally, or through a family member, have an investment or ownership interest in, or a compensation arrangement with, the clinical laboratory performing the tests. A person who engages in a scheme to circumvent the Stark Law’s referral prohibition may be fined up to $100,000 for each such arrangement or scheme. In addition, any person who presents or causes to be presented a claim to the Medicare or Medicaid programs in violation of the Stark Law is subject to civil monetary penalties of up to $15,000 per bill submission, an assessment of up to three times the amount claimed and possible exclusion from participation in federal governmental payor programs. Bills submitted in violation of the Stark Law may not be paid by Medicare or Medicaid, and any person collecting any amounts with respect to any such prohibited bill is obligated to refund such amounts. Many states have comparable laws that are not limited to Medicare and Medicaid referrals.

Corporate Practice of Medicine

Numerous states have enacted laws prohibiting business corporations, such as us, from practicing medicine and employing or engaging physicians to practice medicine, generally referred to as the prohibition against the corporate practice of medicine. These laws are designed to prevent interference in the medical decision-making process by anyone who is not a licensed physician. Violation of these laws may result in civil or criminal fines, as well as sanctions imposed against us and/or the professional through licensure proceedings.

New Jersey and New York State Laboratory Licensing

Our laboratory is licensed and in good standing under both the New Jersey and the New York State Departments of Health standards. Our current licenses permit us to receive specimens obtained in those states.

New Jersey and New York state laws and regulations also establish standards for the day-to-day operations of clinical laboratories, including physical facility requirements and equipment and quality control. New York standards include proficiency testing requirements, even for a laboratory not located in New York. In addition, the New York Department of Health separately approves certain LDTs offered in New York State. The Company has obtained the requisite approvals for its LDTs. If we are found to be out of compliance with New Jersey or New York statutory or regulatory standards we may be subject to suspension, restriction or revocation of our laboratory license or assessed civil money penalties. A noncompliant laboratory may also be found guilty of a misdemeanor under New Jersey and New York laws. A finding of noncompliance, therefore, may result in harm to our business.

Other States’ Laboratory Testing

In addition to New York, several other states require the licensure of out-of-state laboratories that accept specimens from those states, even though we are physically located in New Jersey. We have obtained licenses in these states and believe we are in compliance with their applicable licensing laws. Among the other states that require our laboratory to be licensed is the State of California. We believe we are currently in compliance with these requirements.

33

From time to time, other states may require out of state laboratories to obtain licensure in order to accept specimens from the state. If we identify any other state with such requirements or if we are contacted by any other state advising us of such requirements, we intend to follow instructions from the state regulators as to how we should comply with such requirements.

Other Regulatory Requirements

Our laboratory is subject to federal, state and local regulations relating to the handling and disposal of regulated medical waste, hazardous waste and biohazardous waste, including chemical, biological agents and compounds, blood and bone marrow samples and other human tissue. Typically, we use outside vendors who are contractually obligated to comply with applicable laws and regulations to dispose of such waste. These vendors are licensed or otherwise qualified to handle and dispose of such waste.

OSHA has established extensive requirements relating to workplace safety for health care employers, including requirements to develop and implement programs to protect workers from exposure to blood-borne pathogens by preventing or minimizing any exposure through needle stick or similar penetrating injuries.

Segment and Geographical Information

We operate in one reportable business segment and derive revenue from multiple countries, with 97%, 97% and 92% coming from the United States in fiscal year 2014, 2013 and 2012, respectively.

Employees

As of December 31, 2014, we had a total of 139 full-time and 10 part-time employees, 35% of which hold graduate degrees including 20 doctorate degrees and 14 of which are engaged in full-time research and development activities. We plan to expand production, sales and marketing and our research and development programs, and we plan to hire additional staff as these initiatives are implemented. None of our employees are represented by a labor union, and we consider our employee relations to be good.

Corporate and Available Information

We were incorporated in the State of Delaware on April 8, 1999. On July 16, 2014 we purchased substantially all of the assets of Gentris Corporation ("Gentris"), a laboratory specializing in pharmacogenomics profiling for therapeutic development, companion diagnostics and clinical trials. On August 18, 2014 we entered into two agreements by which we acquired BioServe Biotechnologies (India) Pvt. Ltd.

Item 1A. Risk Factors.

Risks Relating to Our Financial Condition and Capital Requirements

We are an early stage company with a history of net losses; we expect to incur net losses in the future, and we may never achieve sustained profitability.

34

We have historically incurred substantial net losses. We incurred losses of $16.6 million, $12.4 million and $6.7 million for fiscal years ended December 31, 2014, 2013 and 2012, respectively. From our inception in April 1999 through December 31, 2014, we had an accumulated deficit of $78.0 million. We expect our losses to continue principally as a result of ongoing research and development expenses and increased sales and marketing costs. These losses have had, and will continue to have, an adverse effect on our working capital, total assets and stockholders’ equity. Because of the numerous risks and uncertainties associated with our research, development and commercialization efforts, we are unable to predict when we will become profitable, and we may never become profitable. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our inability to achieve and then maintain profitability would negatively affect our business, financial condition, results of operations and cash flows.

We may need to raise additional capital to fund our existing operations, to develop, validate and commercialize new tests and technologies, to expand our operations and repay indebtedness.

We may need to raise additional financing to fund our current level of operations. For the year ended December 31, 2014, net cash used in operating activities was $12.3 million. We also need capital to fund our capital contributions of up to $4.0 million to our joint venture with Mayo and to satisfy indebtedness of approximately $6.0 million due to Wells Fargo Bank. We believe that our current cash will support our operations for 24 months. We can provide no assurances that any additional sources of financing will be available to us on favorable terms, if at all, when needed. Our forecast of the period of time through which our current financial resources will be adequate to support our operations and the costs to support our general and administrative, sales and marketing and research and development activities are forward-looking statements and involve risks and uncertainties.

Additional financing, which is not in place at this time, may be from the sale of equity or convertible or other debt securities in a public or private offering, from an additional or new credit facility or from strategic partnership coupled with an investment in us or a combination of forms. We may be unable to raise sufficient additional financing on terms that are acceptable to us, if at all. Our failure to raise additional capital and in sufficient amounts when needed may significantly impact our ability to expand our business. For further discussion of our liquidity requirements, see the section entitled “Liquidity and Capital Resources—Capital Resources and Expenditure Requirements”.

We also may need to raise capital to expand our business to meet our long-term business objectives, including to:

• increase our sales and marketing efforts to drive market adoption and address competitive developments;

• fund development, validation and marketing efforts of current and future tests;

• comply with current and evolving regulatory requirements;

• further expand our clinical laboratory operations;

• expand our technologies into other types of cancer;

• acquire, license or invest in technologies;

• acquire or invest in complementary businesses or assets; and

• finance capital expenditures and general and administrative expenses.

Our present and future funding requirements and our forecast of the period of time through which our current financial resources will be adequate to support our operations will depend on many factors, including:

• our ability to achieve revenue growth;

• our ability to obtain approvals for our new diagnostic tests;

• our ability to execute on our marketing and sales strategy for our genomic tests and gain acceptance of our tests in the market;

• our ability to obtain adequate reimbursement from governmental and other third-party payors for our tests and services;

• the costs, scope, progress, results, timing and outcomes of the clinical trials of our diagnostic tests;

• the costs of operating and enhancing our laboratory facilities;

• the costs for funding the operations we recently acquired and our ability to successfully integrate those operations with and into our own;

• the costs of additional general and administrative personnel;

• the timing of and the costs involved in regulatory compliance. particularly in the regulations change;

35

• the costs of maintaining, expanding and protecting our intellectual property portfolio, including potential litigation costs and liabilities;

• our ability to manage the costs of manufacturing our NGS panels, microarrays and FHACT® probe;

• our rate of progress in, and cost of research and development activities associated with, products in research and early development;

• the effect of competing technological and market developments;

• costs related to international expansion; and

• our ability to secure financing and the amount thereof.

The various ways we could raise additional capital carry potential risks. If we raise funds by issuing equity securities, dilution to our stockholders could result. Any equity securities issued also could provide for rights, preferences or privileges senior to those of holders of our common stock. If we raise funds by issuing debt securities, those debt securities would have rights, preferences and privileges senior to those of holders of our common stock. The terms of debt securities issued or borrowings pursuant to a credit agreement could impose significant restrictions on our operations and increase our interest expense. If we raise funds through collaborations and licensing arrangements, we might be required to relinquish significant rights to our technologies or tests, or grant licenses on terms that are not favorable to us.

Additional equity or debt financing might not be available on reasonable terms, if at all. If we cannot secure additional funding when needed, we may have to delay, reduce the scope of or eliminate one or more research and development programs or sales and marketing initiatives. In addition, we may have to work with a partner on one or more of our development programs, which could lower the economic value of those programs to us.

Risks Relating to Our Business and Strategy

If we are unable to increase sales of our laboratory tests and services or to successfully develop and commercialize other proprietary tests, our revenues will be insufficient for us to achieve profitability.

We currently derive substantially all of our revenues from our laboratory testing services. We have only recently begun offering our proprietary NGS panels and microarrays through our CLIA-accredited and state licensed laboratory. We also only recently launched FHACT™ for use as a diagnostic tool for cervical cancer in non-U.S. markets. We are in varying stages of research and development for other diagnostic tests that we may offer.

We also have only recently begun to provide our Biopharma Services and Discovery Services. Biopharma Services are services and tests provided to biopharmaceutical companies and clinical research organizations in connection with phase I, phase II or phase III studies for development of therapeutic drugs. The nature of these services is that they tend to come in relatively large projects but episodically, rather than providing steady sources of revenues. It is unclear at this stage of our development whether we will be able to maintain and grow the number of biopharmaceutical companies and clinical research organizations who will avail themselves of our services, or how regular a flow of drug development projects we will be able to obtain from existing customers.

If we are unable to increase sales of our laboratory tests and services or to successfully develop, validate and commercialize other diagnostic tests, we will not produce sufficient revenues to become profitable.

Our quarterly operating results may be subject to significant fluctuations and may be difficult to forecast.

In recent years, we have been expanding our Biopharma Services and Discovery Services business. The nature of these services is that they tend to come in relatively large projects but episodically, rather than providing steady sources of revenues. The timing, size and duration of our contracts with biopharmaceutical companies and clinical research organizations depend on the size, pace and duration of such customer’s clinical trial, over which we have no control and sometimes limited visibility. In addition, our expense levels are based, in part, on expectation of future revenue levels. A shortfall in expected revenue could, therefore, result in a disproportionate decrease in our net income. As a result, our quarterly operating results may be subject to significant fluctuations and may be difficult to forecast.

If pathologists and oncologists decide not to order our diagnostic tests and/or biopharmaceutical companies and clinical research organizations decide not to use our diagnostic tests and services in connection with their clinical trials, we may be unable to generate sufficient revenue to sustain our business.

To generate demand for our Clinical Services, we will need to educate oncologists and pathologists on the clinical utility, benefits and value of each type of test we provide through published papers, presentations at scientific conferences and one-on-

36

one education sessions by members of our sales force. In addition, we will need to assure oncologists and pathologists of our ability to obtain and maintain adequate reimbursement coverage from third-party payors. To generate demand for our Biopharma Services and Discovery Services, we need to educate biopharmaceutical companies and clinical research organizations on the utility of our genomic-based tests and services to improve the outcomes of clinical trials for new oncology drugs and more rapidly advance targeted therapies through the clinical development process through published papers, presentations at scientific conferences and one-on-one education sessions by members of our sales force. We may need to hire additional commercial, scientific, technical and other personnel to support this process. If we cannot convince medical practitioners, biopharmaceutical companies or clinical research organizations to order our diagnostic tests or other future tests we develop, we will likely be unable to create demand for our tests in sufficient volume for us to achieve sustained profitability.

If we are unable to successfully validate our laboratory tests and services, we will not be able to increase revenues.

Pathologists and oncologists may not order our proprietary tests unless we are able to provide compelling evidence that the tests are useful to patient treatment and produce actionable information with respect to the diagnosis, prognosis and theranosis of the various cancers on which our work is focused. In addition, biopharmaceutical companies and clinical research organizations may not order our proprietary tests unless we are able to provide compelling evidence that such tests improve the outcomes of clinical trials for new oncology drugs and allow biopharmaceutical companies to more rapidly advance targeted therapeutics. While we have validated all of the tests that we currently offer, we believe that we will need to finance and successfully complete additional and more powerful studies, and then effectively disseminate the results of those studies, to drive widespread adoption of our tests and thereby increase our revenues.

The commercial success of our Clinical Services business could be compromised if third-party payors, including managed care organizations and Medicare, do not provide coverage and reimbursement, breach, rescind or modify their contracts or reimbursement policies or delay payments for our molecular diagnostic tests.

Pathologists and oncologists may not order our molecular diagnostic tests unless third-party payors, such as managed care organizations and government payors, such as Medicare and Medicaid, pay a substantial portion of the test price. Coverage and reimbursement by a third-party payor may depend on a number of factors, including a payor’s determination that tests using our technologies are:

• not experimental or investigational;

• medically necessary;

• appropriate for the specific patient;

• cost-effective;

• supported by peer-reviewed publications; and

• included in clinical practice guidelines.

Uncertainty surrounds third-party payor reimbursement of any test incorporating new technology, including tests developed using our microarrays and NGS panels. Technology assessments of new medical tests and devices conducted by research centers and other entities may be disseminated to interested parties for informational purposes. Third-party payors and health care providers may use such technology assessments as grounds to deny coverage for a test or procedure.

Because each payor generally determines for its own enrollees or insured patients whether to cover or otherwise establish a policy to reimburse our diagnostic tests, seeking payor approvals is a time-consuming and costly process. We cannot be certain that coverage for our tests will be provided in the future by additional third-party payors or that existing contracts, agreements or policy decisions or reimbursement levels will remain in place or be fulfilled under existing terms and provisions. If we cannot obtain coverage and reimbursement from private and governmental payors such as Medicare and Medicaid for our current tests, or new tests or test enhancements that we may develop in the future, our ability to generate revenues from our clinical services could be limited, which may have a material adverse effect on our financial condition, results of operations and cash flow. Further, we have experienced in the past, and will likely experience in the future, delays and temporary interruptions in the receipt of payments from third-party payors due to missing documentation and other issues, which could cause delay in collecting our revenue.

Our business depends on our ability to successfully commercialize novel cancer diagnostic tests and services, which is time consuming and complex, and our development efforts may fail.

Our current business strategy focuses on discovering, developing and commercializing molecular diagnostic tests and services. We believe the success of our business depends on our ability to fully validate and commercialize our existing diagnostic tests and services and to develop and commercialize new diagnostic tests. We have multiple tests we are currently offering and in development, but research, development and commercialization of diagnostic tests is time-consuming, uncertain and complex.

37

Tests we currently offer in our laboratory, or any additional technologies that we may develop, may not succeed in reliably diagnosing or predicting the recurrence of cancers with the sensitivity and specificity necessary to be clinically useful, and thus may not succeed commercially. In addition, prior to or an in continuing in conjunction with commercializing our diagnostic tests, we must undertake time-consuming and costly development activities, including clinical studies, and obtain regulatory clearance or approval, which may be denied. This development process involves a high degree of risk, substantial expenditures and will occur over several years. Our development efforts may fail for many reasons, including:

• failure of the tests at the research or development stage;

• difficulty in accessing archival tissue samples, especially tissue samples with known clinical results; or

• lack of sufficient clinical validation data to support the effectiveness of the test.

Tests that appear promising in early development may fail to be validated in subsequent studies, and even if we achieve positive results, we may ultimately fail to obtain the necessary regulatory clearances or approvals. There is substantial risk that our research and development projects will not result in commercial tests, and that success in early clinical trials will not be replicated in later studies. At any point, we may abandon development of a test or be required to expend considerable resources repeating clinical trials, which would adversely impact the timing for generating potential revenues from that test. In addition, as we develop tests, we will have to make significant investments in research, development and marketing resources. If a clinical validation study of a particular test then fails to demonstrate the outlined goals of the study, we might choose to abandon the development of that test. Further, our ability to develop and launch diagnostic tests will likely depend on our receipt of additional funding. If our discovery and development programs yield fewer commercial tests than we expect, we may be unable to execute our business plan, which may adversely affect our business, financial condition and results of operations.

We may not be able to successfully integrate our recent acquisitions into our business and we may not achieve the anticipated benefits of such acquisitions.

In July 2014, we acquired Gentris, which provides genomic testing and pharmacogenomics services to half of the top ten BioPharma companies globally and has participated and performed genomic analysis for over 1,000 clinical trials. Gentris has operations in Raleigh (Research Triangle Park), North Carolina and Shanghai, China. In addition, in August 2014 we acquired BioServe. BioServe is a genomic service and next-generation sequencing company founded in 2002 serving both the research and clinical markets and based a leading genomic service and next-generation sequencing company founded in 2002 serving both the research and clinical markets and based in Hyderabad, India in Hyderabad, India. Our failure to successfully integrate the operations of Gentris and BioServe could have a material adverse effect on our business, operating results and financial condition by reason of our failure to realize a sufficient benefit and financial return on capital expended in connection with these acquisitions.

We expect to realize increased revenues and market penetration as a result of the acquisition of BioServe and Gentris. Achievement of these expected benefits will depend, in part, on how we manage the integration of these businesses into our operations. Our management team has limited experience in purchasing and integrating new businesses, particularly those with operations in emerging markets, such as China and India. If we are unsuccessful in integrating such businesses in a cost-effective manner, we may not realize the expected benefits of these acquisitions and our business, operating results and financial condition may be materially and adversely affected.

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

As part of our business strategy, we may pursue other acquisitions of businesses and assets. We also may pursue strategic alliances and joint ventures that leverage our core technology and industry experience to expand our offerings or distribution. For example, we entered into a joint venture in May 2013 with Mayo Foundation for Education and Research. We have no experience with acquiring other companies and limited experience with forming strategic alliances and joint ventures. We may not be able to find suitable partners or acquisition candidates, and we may not be able to complete such transactions on favorable terms, if at all. If we make any acquisitions, we may not be able to integrate these acquisitions successfully into our existing business, and we could assume unknown or contingent liabilities. Any future acquisitions also could result in significant write-offs or the incurrence of debt and contingent liabilities, any of which could have a material adverse effect on our financial condition, results of operations and cash flows. Integration of an acquired company also may disrupt ongoing operations and require management resources that would otherwise focus on developing our existing business. We may experience losses related to investments in other companies, which could have a material negative effect on our results of operations. We may not identify or complete these transactions in a timely manner, on a cost-effective basis, or at all, and we may not realize the anticipated benefits of any acquisition, technology license, strategic alliance or joint venture.

38

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

Our agreement with Mayo may not proceed successfully.

In November 2011, we entered into an affiliation agreement with the Mayo Foundation for Medical Education and Research, subsequently amended. Under the agreement, we formed a joint venture in May 2013 to focus on developing oncology diagnostic services and tests utilizing next generation sequencing. We have made $2.0 million in capital contributions to that joint venture through December 31, 2014. The agreement requires additional capital contributions by us of up to $4.0 million over the next thirty months, subject to the joint venture achieving certain operational milestones. The operation of the joint venture may also divert management time from operating our business. No assurances can be given that we will be able to fully fund the joint venture agreement, or that, even if funded, the joint venture will ever achieve the research, development and commercial objectives currently contemplated by the parties, such as the discovery and commercialization of new diagnostic tests utilizing next-generation sequencing. If the development efforts of the joint venture do not result in commercially successful tests or services, it will have an adverse effect on our business, financial condition and results of operations.

If we are unable to obtain regulatory clearance or approvals in the United States, if we experience delays in receiving clearance or approvals, or if we do not gain acceptance from other laboratories of any cleared or approved diagnostic tests at their facilities, our growth strategy may not be successful.

We currently offer our proprietary tests in conjunction with our comprehensive panel of laboratory services in our CLIA-accredited laboratory. Because we currently offer these tests and services solely for use within our laboratory, we believe we may market the tests as LDTs. Under current FDA enforcement policies and guidance, LDTs generally do not require FDA premarket clearance or approval before commercialization, and we have marketed our LDTs on that basis (although, the FDA has recently announced that such policy may be changing). However, an element of our long-term strategy is to place molecular diagnostic tests on-site with other laboratories to broaden access to our technology and increase demand for our tests and any future diagnostic tests that we may develop. FDA regulates diagnostic kits sold and distributed through interstate commerce as medical devices. Unless an exemption applies, generally, before a new medical device or a new use for a medical device may be sold or distributed in the United States, the medical device must receive either FDA clearance of a 510(k) pre-market notification or pre-market approval. As a result, before we can market or distribute our tests in the United States for use by other clinical testing laboratories, we must first obtain pre-market clearance or pre-market approval from FDA. We have not yet applied for clearance or approval from FDA, and need to complete additional validations before we are ready to apply. We believe it would likely take two years or more to conduct the studies and trials necessary to obtain approval from FDA to commercially launch any of our proprietary products outside of our clinical laboratory. Once we do apply, we may not receive FDA clearance or approval for the commercial use of our tests on a timely basis, or at all. If we are unable to achieve clearance or approval or if clinical diagnostic laboratories do not accept our tests, our ability to grow our business by deploying our tests could be compromised.

Recent announcements from the Federal Food and Drug Administration may impose additional regulatory obligations and costs upon our business.

On October 3, 2014 the FDA issued two draft guidance documents regarding oversight of laboratory developed tests (LDTs). The two draft guidance documents are entitled “Framework for Regulatory Oversight of Laboratory Developed Tests (LDTs)” (the “Framework Guidance”) and “FDA Notification and Medical Device Reporting for Laboratory Developed Test (LDTs)” (the “Notification Guidance”). According to the Framework Guidance, FDA plans to take a phased-in risk-based approach to regulating LDTs. FDA has proposed in the Framework Guidance that there will be three groups of LDTs: (i) LDTs subject to full enforcement discretion, (ii) LDTs subject to partial enforcement discretion; and (iii) LDTs subject to full FDA regulation. FDA plans to phase in enforcement of LTD premarket review, quality system oversight and adverse event reporting over a number of years. Under this new risk based approach, it is possible that some level of pre-market review may be required for our LDTs-either a 510(k) or PMA-which may require us to obtain additional clinical data. The draft guidance documents are subject to public comment. The final date for comments was February 2, 2015, after which time the FDA will review the comments. The FDA has noted that while it has always asserted the power to regulate LDTs, it has chosen not to do so to date as a matter of enforcement discretion. We cannot tell at this time what additional costs and regulatory burdens, any final FDA guidance or FDA enforcement of its regulations may have on our business or operations.

39

If we are unable to execute our marketing strategy for our cancer diagnostic tests and are unable to gain acceptance in the market, we may be unable to generate sufficient revenue to sustain our business.

We are an early-stage company and have engaged in only limited sales and marketing activities for the diagnostic tests and services offered in our clinical laboratory. To date, we have received very limited revenue from sales of our tests.

Although we believe that our diagnostic tests represent promising commercial opportunities, our tests may never gain significant acceptance in the marketplace and therefore may never generate substantial revenue or profits for us. We will need to establish a market for our diagnostic tests and build that market through physician education and awareness programs. Gaining acceptance in medical communities requires that we perform additional studies after validating the efficacy of our tests and services for the diagnosis, prognosis and treatment of cancer, and that we obtain acceptance of the results of those studies using our tests for publication in leading peer-reviewed medical journals. The results of any studies are always uncertain and even if we believe such studies demonstrate the value of our tests, they process of publication in leading medical journals is subject to a peer review process and peer reviewers may not consider the results of our studies sufficiently novel or worthy of publication. Failure to have our studies published in peer-reviewed journals would limit the adoption of our tests. Our ability to successfully market the diagnostic tests that we may develop will depend on numerous factors, including:

• whether healthcare providers believe our diagnostic tests provide clinical utility;

• whether the medical community accepts that our diagnostic tests are sufficiently sensitive and specific to be meaningful in patient care and treatment decisions; and

• whether health insurers, government health programs and other third-party payors will cover and pay for our diagnostic tests and, if so, whether they will adequately reimburse us.

Failure to achieve widespread market acceptance of our diagnostic tests would materially harm our business, financial condition and results of operations.

If we cannot develop tests to keep pace with rapid advances in technology, medicine and science, our operating results and competitive position could be harmed.

In recent years, there have been numerous advances in technologies relating to the diagnosis and treatment of cancer. There are several new cancer drugs under development that may increase patient survival time. There have also been advances in methods used to analyze very large amounts of genomic information. We must continuously develop new tests and enhance our existing tests to keep pace with evolving standards of care. Our existing tests could become obsolete unless we continually innovate and expand them to demonstrate benefit in patients treated with new therapies. New cancer therapies typically have only a few years of clinical data associated with them, which limits our ability to perform clinical studies and correlate sets of genes to a new treatment’s effectiveness. If we cannot adequately demonstrate the applicability of our tests to new treatments, sales of our tests and services could decline, which would have a material adverse effect on our business, financial condition and results of operations.

If our tests do not continue to perform as expected, our operating results, reputation and business will suffer.

Our success depends on the market’s confidence that we can continue to provide reliable, high-quality diagnostic tests. We believe that our customers are likely to be particularly sensitive to test defects and errors. As a result, the failure of our tests or services to perform as expected would significantly impair our reputation and the public image of our tests and services, and we may be subject to legal claims arising from any defects or errors.

There is a scarcity of experienced professionals in our industry. If we are not able to retain and recruit personnel with the requisite technical skills, we may be unable to successfully execute our business strategy.

The specialized nature of our industry results in an inherent scarcity of experienced personnel in the field. Our future success depends upon our ability to attract and retain highly skilled personnel (including medical, scientific, technical, commercial, business, regulatory and administrative personnel) necessary to support our anticipated growth, develop our business and perform certain contractual obligations. Given the scarcity of professionals with the scientific knowledge that we require and the competition for qualified personnel among life science businesses, we may not succeed in attracting or retaining the personnel we require to continue and grow our operations. The loss of a key employee, the failure of a key employee to perform in his or her current position or our inability to attract and retain skilled employees could result in our inability to continue to grow our business or to implement our business strategy.

40

Our inability to attract, hire and retain a sufficient number of qualified sales professionals would hamper our ability to increase demand for our tests, to expand geographically and to successfully commercialize any other diagnostic tests or products we may develop.

Our success in selling our clinical laboratory services, biopharma services, discovery services, diagnostic tests and any other tests or products that we are able to develop will require us to expand our sales force in the United States and internationally by recruiting additional sales representatives with extensive experience in oncology and close relationships with medical oncologists, surgeons, pathologists and other hospital personnel, as well as biopharmaceutical companies and clinical research organizations. To achieve our marketing and sales goals, we will need to substantially expand our sales and commercial infrastructure, with which to date we have had little experience. Sales professionals with the necessary technical and business qualifications are in high demand, and there is a risk that we may be unable to attract, hire and retain the number of sales professionals with the right qualifications, scientific backgrounds and relationships with decision-makers at potential customers needed to achieve our sales goals. We may face competition from other companies in our industry, some of whom are much larger than us and who can pay greater compensation and benefits than we can, in seeking to attract and retain qualified sales and marketing employees. If we are unable to hire and retain qualified sales and marketing personnel, our business will suffer.

We have indebtedness with restrictive covenants that limit our ability to obtain additional debt financing and that requires us to restrict cash as collateral, which could have a material adverse effect on our financial condition, our ability to fund operations, and react to changes in our business.

As of December 31, 2014, we had indebtedness for borrowed money due on April 1, 2016 in the aggregate principal amount of $6.0 million under a line of credit with Wells Fargo. We are required to restrict $6.0 million in cash as collateral. Additionally, we are required to maintain limits on capital spending and are restricted as to the amount we may pledge as collateral for additional borrowings from any source. Our debt and related covenants could limit our ability to satisfy our obligations, limit our ability to operate our business and impair our competitive position. For example, it could:

• require us to dedicate a substantial portion of our cash flow from operations to payments on our debt, reducing the availability of our cash flow from operations to fund working capital, capital expenditures or other general corporate purposes;

• limit our flexibility in planning for, or reacting to, changes in our business and industry;

• place us at a disadvantage compared to competitors that may have proportionately less debt; and

• increase our cost of borrowing.

If our laboratory facilities become damaged or inoperable, or we are required to vacate any facility, our ability to provide services and pursue our research and development efforts may be jeopardized.

We currently derive substantially all of our revenues from our laboratory testing services. We do not have any clinical reference laboratory facilities outside of our facilities in Rutherford, New Jersey, Morrisville, North Carolina and Hyderabad, India. Our facilities and equipment could be harmed or rendered inoperable by natural or man-made disasters, including fire, flooding and power outages, which may render it difficult or impossible for us to perform our tests or provide laboratory services for some period of time. The inability to perform our tests or the backlog of tests that could develop if any of our facilities is inoperable for even a short period of time may result in the loss of customers or harm to our reputation or relationships with collaborators, and we may be unable to regain those customers or repair our reputation in the future. Furthermore, our facilities and the equipment we use to perform our research and development work could be costly and time-consuming to repair or replace.

Additionally, a key component of our research and development process involves using biological samples and the resulting data sets and medical histories, as the basis for our diagnostic test development. In some cases, these samples are difficult to obtain. If the parts of our laboratory facilities where we store these biological samples are damaged or compromised, our ability to pursue our research and development projects, as well as our reputation, could be jeopardized. We carry insurance for damage to our property and the disruption of our business, but this insurance may not be sufficient to cover all of our potential losses and may not continue to be available to us on acceptable terms, if at all.

Further, if any of our laboratories became inoperable we may not be able to license or transfer our proprietary technology to a third-party, with established state licensure and CLIA accreditation under the scope of which our diagnostic tests could be performed following validation and other required procedures, to perform the tests. Even if we find a third-party with such qualifications to perform our tests, such party may not be willing to perform the tests for us on commercially reasonable terms.

41

If we cannot compete successfully with our competitors, we may be unable to increase or sustain our revenues or achieve and sustain profitability.

We face competition from mainstream diagnostic methods that pathologists and oncologists use and have used for many years. It may be difficult to change the methods or behavior of the referring pathologists and oncologists to incorporate our molecular diagnostic testing in their practices. We believe that we can introduce our diagnostic tests successfully due to their clinical utility and the desire of pathologists and oncologists to find solutions for more accurate diagnosis, prognosis and personalized treatment options for cancer patients.

We also face competition from companies that currently offer or are developing products to profile genes, gene expression or protein biomarkers in various cancers. Personalized genetic diagnostics is a new area of science, and we cannot predict what tests others will develop that may compete with or provide results superior to the results we are able to achieve with the tests we develop. Our competitors include public companies such as NeoGenomics, Inc., Quest Diagnostics, Abbott Laboratories, Inc., Johnson & Johnson, Roche Molecular Systems, Inc., bioTheranostics, Inc. (part of bioMérieux SA), Genomic Health, Inc., Myriad Genetics Inc., Response Genetics, Inc., and Foundation Medicine, Inc., and many private companies. We expect that pharmaceutical and biopharmaceutical companies will increasingly focus attention and resources on the personalized diagnostic sector as the potential and prevalence increases for molecularly targeted oncology therapies approved by FDA along with companion diagnostics. For example, FDA has recently approved two such agents—Xalkori crizotinib from Pfizer Inc. along with its companion anaplastic lymphoma kinase FISH test from Abbott Laboratories, Inc. and Zelboraf vemurafenib from Genentech USA Incorporated and Daiichi-Sankyo Inc. along with its companion B-RAF kinase V600 mutation test from Roche Molecular Systems, Inc. These two recent FDA approvals are only the second and third instances of simultaneous approvals of a drug and companion diagnostic, the first being the 1998 approval of Genentech, Inc.’s Herceptin trastuzumab for HER2 positive breast cancer along with the HercepTest from partner Dako A/S.

With respect to our clinical laboratory sciences business we face competition from companies such as Genoptix, Inc. (a Novartis AG Company), Clarient, Inc. (a division of GE Healthcare, a unit of General Electric Company), Bio-Reference Laboratories, Inc., and Genzyme Genetics (a LabCorp Specialty Testing Group).

Many of our present and potential competitors have widespread brand recognition and substantially greater financial and technical resources and development, production and marketing capabilities than we do. Others may develop lower-priced, less complex tests that payors, pathologists and oncologists could view as functionally equivalent to our tests, which could force us to lower the list price of our tests and impact our operating margins and our ability to achieve profitability. In addition, technological innovations that result in the creation of enhanced diagnostic tools may enable other clinical laboratories, hospitals, physicians or medical providers to provide specialized diagnostic services similar to ours in a more patient-friendly, efficient or cost-effective manner than is currently possible. If we cannot compete successfully against current or future competitors, we may be unable to increase market acceptance and sales of our tests, which could prevent us from increasing or sustaining our revenues or achieving or sustaining profitability.

A small number of test ordering sites account for most of the sales of our tests and services. If any of these sites orders fewer tests from us for any reason, our revenues could decline.

Due to the early stage nature of our business and our limited sales and marketing activities to date, we have historically derived a significant portion of our revenue from a limited number of test ordering sites, although the test ordering sites that generate a significant portion of our revenue may change from period to period. Our test ordering sites are largely hospitals, cancer centers, reference laboratories and physician offices, as well as biopharmaceutical companies as part of a clinical trial. Oncologists and pathologists at these sites order the tests on behalf of the needs of their oncology patients or as part of a clinical trial sponsored by a biopharmaceutical company in which the patient is being enrolled. The top five test ordering sites during 2014, 2013 and 2012 accounted for 56%, 69% and 58% respectively, of our clinical testing volumes, with 38%, 36% and 46% respectively, of the volume coming from community hospitals. During the year ended December 31, 2014, two Biopharma clients accounted for approximately 23% and 12% respectively of our revenue. During the year ended December 31, 2013 there was one Biopharma client that accounted for approximately 40% of our revenue. During 2012 there were three sites which each accounted for more than 10% of our revenue: a Biopharma client accounted for approximately 13%, a university teaching center accounted for approximately 11% and a community hospital accounted for approximately 10% of our revenue.

We expect to continue to incur significant expenses to develop and market our diagnostic tests, which could make it difficult for us to achieve and sustain profitability.

In recent years, we have incurred significant costs in connection with the development of our diagnostic tests. For the year ended December 31, 2014, our research and development expenses were $4.6 million, which was 45% of our net revenue and

42

our sales and marketing expenses were $4.0 million, which was 39% of revenue. For the year ended December 31, 2013, our research and development expenses were $2.2 million, which was 33% of our revenue, and our sales and marketing expenses were $1.8 million, which was 28% of revenue. For the year ended December 31, 2012, our research and development expenses were $2.1 million, which was 49% of our revenue and our sales and marketing expenses were $1.4 million, which was 33% of revenue. We expect our expenses to continue to increase, in absolute dollars, for the foreseeable future as we seek to expand the clinical utility of our diagnostic tests, drive adoption of and reimbursement for our diagnostic tests and develop new tests. As a result, we will need to generate significant revenues in order to achieve sustained profitability.

We depend on certain collaborations with third parties for the supply of certain tissue samples and biological materials that we use in our research and development efforts. If the costs of such collaborations increase or our third party collaborators terminate their relationship with us, our business may be materially harmed.

Under standard clinical practice in the United States, tumor biopsies removed from patients are chemically preserved, embedded in paraffin wax and stored. Our clinical development relies on our ability to access these archived tumor biopsy samples, as well as information pertaining to their associated clinical outcomes. Other companies often compete with us for access. Additionally, the process of negotiating access to archived samples is lengthy, because it typically involves numerous parties and approvals to resolve complex issues such as usage rights, institutional review board approval, privacy rights, publication rights, intellectual property ownership and research parameters.

We have collaborative relationships with Memorial Sloan-Kettering Cancer Center, Mayo, North Shore—Long Island Jewish Health System, the National Cancer Institute, the Cleveland Clinic and other institutions who provide us with tissue samples and other biological materials that we use in developing and validating our tests. We do not have any written arrangement with certain third party collaborators, and in many of the cases in which the arrangements are in writing, our collaborative relationships are terminable on 30 days’ notice or less. If one or more collaborators terminate their relationship with us, we will need to identify other third parties to provide us with tissue samples and biological materials, which could result in a delay in our research and development activities and negatively affect our business.

We currently rely on a single third-party to produce our microarrays and any problems experienced by this vendor could result in a delay or interruption in the supply of our microarrays to us until the problem is cured by such vendor or until we locate and qualify an alternative source of supply.

The design of our microarrays is currently optimized on a family of instruments referred to as the Agilent Microarray Platform, which is currently produced solely by Agilent Technologies Inc. (“Agilent”). We currently purchase these components from Agilent under purchase orders and do not have a long-term contract with Agilent. If Agilent were to delay or stop producing our microarrays, or if the prices Agilent charges us were to increase significantly, we would need to identify another supplier and optimize our microarrays on a new technology platform. We could experience delays in manufacturing the microarrays while finding another acceptable supplier, which could impact our results of operations. The changes could also result in increased costs associated with migrating to the new technology platform and in increased manufacturing costs. Further, any prolonged disruption in Agilent’s operations could have a significant negative impact on the supply of our microarrays.

If we were sued for product liability or professional liability, we could face substantial liabilities that exceed our resources.

The marketing, sale and use of our tests could lead to the filing of product liability claims were someone to allege that our tests failed to perform as designed. We may also be subject to liability for errors in the test results we provide to pathologists and oncologists or for a misunderstanding of, or inappropriate reliance upon, the information we provide. A product liability or professional liability claim could result in substantial damages and be costly and time-consuming for us to defend.

Although we believe that our existing product and professional liability insurance is adequate, our insurance may not fully protect us from the financial impact of defending against product liability or professional liability claims. Any product liability or professional 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 damage our reputation, result in the recall of our tests, or cause current clinical partners to terminate existing agreements and potential clinical partners to seek other partners, any of which could impact our results of operations.

If we use biological and hazardous materials in a manner that causes injury, we could be liable for damages.

Our activities currently require the controlled use of potentially harmful biological materials and hazardous materials and chemicals. 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

43

resulting damages, and any liability could exceed our resources or any applicable insurance coverage we may have. Additionally, we are subject to, on an ongoing basis, federal, state and local laws and regulations governing the use, storage, handling and disposal of these materials and specified waste products. The cost of compliance with these laws and regulations may become significant and could have a material adverse effect on our financial condition, results of operations and cash flows. In the event of an accident or if we otherwise fail to comply with applicable regulations, we could lose our permits or approvals or be held liable for damages or penalized with fines.

If we cannot support demand for our tests, including successfully managing the evolution of our technology and manufacturing platforms, our business could suffer.

As our test volume grows, we will need to increase our testing capacity, implement increases in scale and related processing, customer service, billing, collection and systems process improvements and expand our internal quality assurance program and technology to support testing on a larger scale. We will also need additional certified laboratory scientists and other scientific and technical personnel to process these additional tests. Any increases in scale, related improvements and quality assurance may not be successfully implemented and appropriate personnel may not be available. As additional tests are commercialized, we will need to bring new equipment on line, implement new systems, technology, controls and procedures and hire personnel with different qualifications. Failure to implement necessary procedures or to hire the necessary personnel could result in a higher cost of processing or an inability to meet market demand. We cannot assure you that we will be able to perform tests on a timely basis at a level consistent with demand, that our efforts to scale our commercial operations will not negatively affect the quality of our test results or that we will respond successfully to the growing complexity of our testing operations. If we encounter difficulty meeting market demand or quality standards for our tests, our reputation could be harmed and our future prospects and business could suffer, which may have a material adverse effect on our financial condition, results of operations and cash flows.

We depend on our information technology and telecommunications systems, and any failure of these systems could harm our business.

We depend on information technology and telecommunications systems for significant aspects of our operations. In addition, our third-party billing and collections provider depends upon telecommunications and data systems provided by outside vendors and information we provide on a regular basis. These information technology and telecommunications systems support a variety of functions, including test processing, sample tracking, quality control, customer service and support, billing and reimbursement, research and development activities and our general and administrative activities. Information technology and telecommunications systems are vulnerable to damage from a variety of sources, including telecommunications or network failures, malicious human acts and natural disasters. Moreover, despite network security and back-up measures, some of our servers are potentially vulnerable to physical or electronic break-ins, computer viruses and similar disruptive problems. Despite the precautionary measures we have taken to prevent unanticipated problems that could affect our information technology and telecommunications systems, failures or significant downtime of our information technology or telecommunications systems or those used by our third-party service providers could prevent us from processing tests, providing test results to pathologists, oncologists, billing payors, processing reimbursement appeals, handling patient or physician inquiries, conducting research and development activities and managing the administrative aspects of our business. Any disruption or loss of information technology or telecommunications systems on which critical aspects of our operations depend could have an adverse effect on our business.

Security breaches, loss of data, and other disruptions 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 our reputation.

In the ordinary course of our business, we and our third-party billing and collections provider collect and store sensitive data, including legally protected health information, personally identifiable information, intellectual property, and proprietary business information owned or controlled by ourselves or our customers, payors, and biopharmaceutical partners. The secure processing, storage, maintenance, and transmission of this critical information is 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, and that of our third-party billing and collections provider, may be vulnerable to attacks by hackers or viruses or breached due to employee error, malfeasance, or other disruptions. Any such breach or interruption could compromise our networks, and the information stored there could be accessed by unauthorized parties, publicly disclosed, lost, or stolen. Any such access, disclosure, or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information, such as the HIPAA, and regulatory penalties. Unauthorized access, loss, or dissemination could also disrupt our operations, including our

44

ability to conduct our analyses, provide test results, bill payors or patients, process claims and appeals, provide customer assistance services, conduct research and development activities, collect, process, and prepare company financial information, provide information about our products and other patient and physician education and outreach efforts through our website, manage the administrative aspects of our business, and damage our reputation, any of which could adversely affect our business.

The U.S. Office of Civil Rights may impose penalties on a covered entity for a failure to comply with a requirement of HIPAA. Penalties will vary significantly depending on factors such as the date of the violation, whether the covered entity knew or should have known of the failure to comply, or whether the covered entity’s failure to comply was due to willful neglect. These penalties include civil monetary penalties of $100 to $50,000 per violation, up to an annual cap of $1,500,000. A person who knowingly obtains or discloses individually identifiable health information in violation of HIPAA may face a criminal penalty of up to $50,000 and up to one year imprisonment. The criminal penalties increase to $100,000 and up to five years imprisonment if the wrongful conduct involves false pretenses, and to $250,000 and up to 10 years imprisonment if the wrongful conduct involves the intent to sell, transfer, or use identifiable health information for commercial advantage, personal gain, or malicious harm. The U.S. Department of Justice is responsible for criminal prosecutions under HIPAA. Furthermore, in the event of a breach as defined by HIPAA, the covered entity has specific reporting requirements under the HIPAA regulations. In the event of a significant breach, the reporting requirements could include notification to the general public.

In addition, the interpretation and application of consumer, health-related, and data protection laws in the United States, Europe, and elsewhere 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. In addition, these privacy regulations may differ from country to country, and may vary based on whether testing is performed in the United States or in the local country. Complying with these various laws could cause us to incur substantial costs or require us to change our business practices and compliance procedures in a manner adverse to our business.

Regulatory Risks Relating to Our Business

Healthcare policy changes, including recently enacted legislation reforming the U.S. health care system, may have a material adverse effect on our financial condition, results of operations and cash flows.

In March 2010, U.S. President Barack Obama signed the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act (collectively, “PPACA”), which makes a number of substantial changes in the way health care is financed by both governmental and private insurers. Among other things, the PPACA:

• Requires each medical device manufacturer to pay a sales tax equal to 2.3% of the price for which such manufacturer sells its medical devices, beginning in 2013. This tax may apply to some or all of our current products and products which are in development.

• Mandates a reduction in payments for clinical laboratory services paid under the Medicare Clinical Laboratory Fee Schedule of 1.75% for the years 2011 through 2015. In addition, a productivity adjustment is made to the fee schedule payment amount. These changes in payments apply to some or all of the clinical laboratory test services we furnish to Medicare beneficiaries.

• Establishes an Independent Payment Advisory Board to reduce the per capita rate of growth in Medicare spending. The Independent Payment Advisory Board has broad discretion to propose policies, which may have a negative impact on payment rates for services, including clinical laboratory services, beginning in 2016, and for hospital services beginning in 2020.

Although some of these provisions may negatively impact payment rates for clinical laboratory services, the PPACA also extends coverage to approximately 32 million previously uninsured people, which may result in an increase in the demand for our tests and services. The mandatory purchase of insurance has been strenuously opposed by a number of state governors, resulting in lawsuits challenging the constitutionality of certain provisions of the PPACA. On June 28, 2012, the Supreme Court upheld the constitutionality of the health care reform law, with the exception of certain provisions dealing with the expansion of Medicaid coverage under the law. Therefore, most of the law’s provisions will go into effect in 2013 and 2014. Congress has also proposed a number of legislative initiatives, including possible repeal of the PPACA. Recently, the Supreme Court heard arguments in the case of Burwell v. King, which considers whether the it was permissible for the federal government to extend tax subsidies to those individuals who purchased coverage through federal exchanges, in addition to the exchanges established by individual states. If the Court were to find that subsidies to those who purchased through the federal exchanges were not permissible, it is possible that many individuals would be unable to afford to purchase coverage. This would significantly affect the viability of PPACA.

In addition, other legislative changes have been proposed and adopted since the PPACA was enacted. Recently, on August 2, 2011, the President signed into law the Budget Control Act of 2011, which, among other things, creates the Joint Select Committee on Deficit Reduction to recommend proposals in spending reductions to Congress. The Joint Select Committee did not achieve a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, triggering the legislation’s automatic reduction to several government programs. This includes aggregate reductions to Medicare payments to providers of up to 2% per fiscal year, starting in 2013. This 2% sequester was recently extended through 2024.

The full impact on our business of the PPACA and the new law is uncertain. In addition, on February 22, 2012, the President signed the Middle Class Tax Relief and Job Creation Act of 2012 (“MCTRJCA”), which, among other things, mandated an additional change in Medicare reimbursement for clinical laboratory services. This legislation requires a rebasing of the Medicare clinical laboratory fee schedule to effect a 2% reduction in payment rates otherwise determined for 2013. This will serve as a base for 2014 and subsequent years. As a result of the changes mandated by PPACA and MCTRJCA, CMS projects laboratory services for 2015 will be reduced by approximately 0.25%.

Further, in 2014, Congress passed the Protecting Access to Medicare Act or PAMA which also makes significant changes in the way the Medicare will pay for laboratory services. Under PAMA, laboratories will be required to report the amount that they are paid by third party payors for each test beginning in January 2016. CMS will use this data to calculate a weighted median for each test. That new price will become effective on January 1, 2017, although any resulting reductions will be phased in over time. This data reporting process will be repeated every three years for most tests, although certain advanced diagnostic tests will have to report every year. It is possible that some of our tests may qualify as Advanced Diagnostic Laboratory Tests, which will require us to submit pricing annually. In addition, under PAMA, we will also be required to obtain new codes from CMS or any entity it designates, for our tests that do not currently have codes. If PAMA results in a significant reduction in the prices for our tests, it could have a significant impact on our revenues.

Certain of our laboratory services are paid under the Medicare Physician Fee Schedule and, under the current statutory formula, the rates for these services are updated annually. For the past several years, the application of the statutory formula would have resulted in substantial payment reductions if Congress failed to intervene. In the past, Congress passed interim legislation to prevent the decreases. On November 1, 2012, the Centers for Medicare & Medicaid Services (CMS) issued the Final Rule. In the Final Rule, CMS called for a reduction of approximately 26.5% in the 2013 conversion factor that is used to calculate physician reimbursement. However, the American Taxpayer Relief Act of 2012, which was signed into law on January 2, 2013, prevents this proposed cut and keeps the current reimbursement rate in effect until December 31, 2013. For 2014, CMS had projected the reimbursement cut resulting from the SGR formula would be approximately 20 percent, unless Congress acted to prevent the reduction. On December 18, 2013, Congress passed legislation that enacted a 0.5 percent increase in the conversion factor, which was effective until March 31, 2014. On April 1, 2014, President Obama signed the Protecting Access to Medicare Act of 2014, or PAMA. PAMA extended the 0.5 percent increase through March 31, 2015 and made other changes to laboratory reimbursement discussed below. Currently, Congress is considering an extension of the increase enacted by PAMA. If Congress fails to act before March 31, 2015, or if it does not enact a long-term change to the SGR, then future decreases in the Medicare physician schedule are possible. If Congress fails to act in future years to offset similar proposed reductions, the resulting decrease in payment could adversely impact our revenues and results of operations.

In addition, many of the Current Procedure Terminology (“CPT”) procedure codes that we use to bill our tests were revised by the AMA, effective January 1, 2013. In the Final Rule, CMS announced that it has decided to keep the new molecular codes on the Clinical Laboratory Fee Schedule (CLFS), rather than move them to the Physician Fee Schedule as some stakeholders had urged. CMS also announced that for 2013 it would price the new codes using a “gapfilling” process by which it will refer the codes to the Medicare contractors to allow them to determine an appropriate price. Those prices were determined and became effective January 1, 2014. In addition, CMS also stated that it would not recognize certain of the new codes for Multi-analyte Assays for Algorithmic Assays (MAAAs) because it does not believe they qualify as clinical laboratory tests. However, more recently, it has determined that the individual contractors may determine whether to pay for MAAA tests on a case by case basis. Our reimbursement could be adversely affected by CMS’ action in this area. There can be no guarantees that Medicare and other payors will establish positive or adequate coverage policies or reimbursement rates.

We cannot predict whether future health care initiatives will be implemented at the federal or state level, or how any future legislation or regulation may affect us. The taxes imposed by the new federal legislation and the expansion of government’s role in the U.S. health care industry as well as changes to the reimbursement amounts paid by payors for our products or our medical procedure volumes may reduce our profits and have a materially adverse effect on our business, financial condition, results of operations and cash flows. Moreover, Congress has proposed on several occasions to impose a 20% coinsurance on patients for clinical laboratory tests reimbursed under the clinical laboratory fee schedule, which would require us to bill patients for these amounts. Because of the relatively low reimbursement for many clinical laboratory tests, in the event that Congress were to ever enact such legislation, the cost of billing and collecting for these services would often exceed the amount actually received from the patient and effectively increase our costs of billing and collecting.

46

We depend on Medicare and a limited number of private payors for a significant portion of our revenues and if these or other payors stop providing reimbursement or decrease the amount of reimbursement for our tests, our revenues could decline.

For the year ended December 31, 2014, we derived approximately 16% of our total revenue from private insurance, including managed care organizations and other health care insurance providers, 11% from Medicare and 16% from other healthcare facilities billed directly. Medicare and other third-party payors may withdraw their coverage policies or cancel their contracts with us at any time, review and adjust the rate of reimbursement or stop paying for our tests altogether, which would reduce our total revenues.

Payors have increased their efforts to control the cost, utilization and delivery of health care services. In the past, measures have been undertaken to reduce payment rates for and decrease utilization of the clinical laboratory industry generally. Because of the cost-trimming trends, third-party payors that currently cover and provide reimbursement for our tests may suspend, revoke or discontinue coverage at any time, or may reduce the reimbursement rates payable to us. Any such action could have a negative impact on our revenues, which may have a material adverse effect on our financial condition, results of operations and cash flows.

In addition, we are currently considered a “non-contracting provider” by a number of private third-party payors because we have not entered into a specific contract to provide our specialized diagnostic services to their insured patients at specified rates of reimbursement. If we were to become a contracting provider in the future, the amount of overall reimbursement we receive is likely to decrease because we will be reimbursed less money per test performed at a contracted rate than at a non-contracted rate, which could have a negative impact on our revenues. Further, we typically are unable to collect payments from patients beyond that which is paid by their insurance and will continue to experience lost revenue as a result.

Because of certain Medicare billing rules, we may not receive reimbursement for all tests provided to Medicare patients.

Under current Medicare billing rules, claims for our tests performed on Medicare beneficiaries who were hospital inpatients when the tumor tissue samples were obtained and whose tests were ordered less than 14 days from discharge must be incorporated in the payment that the hospital receives for the inpatient services provided. Accordingly, we must bill individual hospitals for tests performed on Medicare beneficiaries during these timeframes in order to receive payment for our tests. Because we generally do not have a written agreement in place with these hospitals that purchase these tests, we may not be paid for our tests or may have to pursue payment from the hospital on a case-by-case basis. In addition, until 2012, we were permitted to bill globally for certain anatomic pathology services we furnished to certain hospitals, i.e. we billed both the technical component and the professional component to Medicare. As part of the Middle Class Tax Relief and Job Creation Act of 2012, Congress terminated the special provision for “grandfathered” hospitals as of July 1, 2012. Therefore, as of that date we were required to bill all hospitals for the technical component of all anatomic pathology services we furnish to their patients, which may be difficult and/or costly for us.

Further, the Medicare Administrative Contractors who process claims for Medicare also can impose their own rules related to coverage and payment for laboratory services provided in their jurisdiction. Recently, Palmetto GBA, the Medicare Administrative Contractor for North Carolina, South Carolina, Virginia and West Virginia, announced a comprehensive new billing policy and a coverage policy applicable to molecular diagnostic tests, such as ours. Under coverage policy, Palmetto will deny payment for molecular diagnostic tests, unless it has issued a positive coverage determination for the test. Other Medicare contractors are also adopting policies similar to Palmetto’s. If any of our tests are subject to the Palmetto policy and/or the Palmetto policy is adopted by other contractors that process claims with hospitals or laboratories that purchase and bill for our tests, our business could be adversely impacted.

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

We are subject to CLIA, a federal law regulating clinical laboratories that perform testing on specimens derived from humans for the purpose of providing information for the diagnosis, prevention or treatment of disease. Our clinical laboratory must be accredited under CLIA in order for us to perform testing on human specimens. In addition, our proprietary tests must also be recognized as part of our accredited programs under CLIA so that we can offer them in our laboratory. CLIA is intended to ensure the quality and reliability of clinical laboratories in the United States by mandating specific standards in the areas of personnel qualifications, administration, and participation in proficiency testing, patient test management, quality control, quality assurance and inspections. We have a current certificate of accreditation under CLIA to perform high complexity testing and our laboratory is accredited by the College of American Pathologists (“CAP”), one of six CLIA-approved accreditation

47

organizations. To renew this certificate, we are subject to survey and inspection every two years. Moreover, CLIA inspectors may make periodic inspections of our clinical reference laboratory outside of the renewal process.

The law also requires us to maintain a state laboratory license to conduct testing in that state. Our laboratory is located in New Jersey and must have a New Jersey state license; as we expand our geographic focus, we may need to obtain laboratory licenses from additional states. New Jersey laws establish standards for day-to-day operation of our clinical reference laboratory, including the training and skills required of personnel and quality control. In addition, several other states require that we hold licenses to test specimens from patients in those states. Other states may have similar requirements or may adopt similar requirements in the future. Finally, we may be subject to regulation in foreign jurisdictions as we seek to expand international distribution of our tests.

If we were to lose our CLIA accreditation or New Jersey laboratory license, whether as a result of a revocation, suspension or limitation, we would no longer be able to offer our tests, which would limit our revenues and harm our business. If we were to lose our license in other states where we are required to hold licenses, we would not be able to test specimens from those states.

If FDA were to begin requiring approval or clearance of our tests, we could incur substantial costs and time delays associated with meeting requirements for pre-market clearance or approval or we could experience decreased demand for, or reimbursement of, our tests.

Although FDA maintains that it has authority to regulate the development and use of LDTs, such as ours, as medical devices, it has not exercised its authority with respect to most LDTs as a matter of enforcement discretion. FDA does not generally extend its enforcement discretion to reagents or software provided by third parties and used to perform LDTs, and therefore these products must typically comply with FDA medical device regulations, which are wide-ranging and govern, among other things: product design and development, product testing, product labeling, product storage, pre-market clearance or approval, advertising and promotion and product sales and distribution.

We believe that our proprietary tests, as utilized in our laboratory testing, are LDTs. As a result, we believe that pursuant to FDA’s current policies and guidance that FDA does not require that we obtain regulatory clearances or approvals for our LDTs. The container we provide for collection and transport of tumor samples from a pathology laboratory to our clinical reference laboratory may be a medical device subject to FDA regulation but is currently exempt from pre-market review by FDA. While we believe that we are currently in material compliance with applicable laws and regulations, we cannot assure you that FDA or other regulatory agencies would agree with our determination, and a determination that we have violated these laws, or a public announcement that we are being investigated for possible violations of these laws, could adversely affect our business, prospects, results of operations or financial condition.

Moreover, FDA guidance and policy pertaining to diagnostic testing is continuing to evolve and is subject to ongoing review and revision. A significant change in any of the laws, regulations or policies may require us to change our business model in order to maintain regulatory compliance. At various times since 2006, FDA has issued guidance documents or announced draft guidance regarding initiatives that may require varying levels of FDA oversight of our tests. For example, in June 2010, FDA announced a public meeting to discuss the agency’s oversight of LDTs prompted by the increased complexity of LDTs and their increasingly important role in clinical decision-making and disease management, particularly in the context of personalized medicine. FDA indicated that it was considering a risk-based application of oversight to LDTs and that, following public input and discussion, it might issue separate draft guidance on the regulation of LDTs, which ultimately could require that we seek and obtain either pre-market clearance or approval of LDTs, depending upon the risk-based approach FDA adopts. The public meeting was held in July 2010 and further public comments were submitted to FDA through September 2010. FDA has stated it is continuing to develop draft guidance in this area. Section 1143 of the Food and Drug Administration Safety and Innovation Act, signed by the U.S. President on July 9, 2012, requires FDA to notify U.S. Congress at least 60 days prior to issuing a draft or final guidance regulating LDTs and provide details of the anticipated action.

48

is continuing to develop draft guidance in this area. Section 1143 of the Food and Drug Administration Safety and Innovation Act, signed by the U.S. President on July 9, 2012, requires FDA to notify U.S. Congress at least 60 days prior to issuing a draft or final guidance regulating LDTs and provide details of the anticipated action.

On July 31, 2014, FDA notified Congress pursuant to the FDASIA that it intended to issue draft Guidances that would regulate LDTs. On October 3, 2014, the FDA issued two separate draft guidances: “Framework for Regulatory Oversight of Laboratory Developed Tests (LDTs)” (“The Framework Draft Guidance”) and “FDA Notification and Medical Device Reporting for Laboratory Developed Tests” (the “Notification Draft Guidance.”). In the Framework Draft Guidance, FDA states that after the Guidances are finalized, it will no longer exercise enforcement discretion with respect to most LDTs and will, instead, regulate them in a risk-based manner consistent with the existing classification of medical devices. Thus, the FDA plans to begin to enforce its medical device requirements, including premarket submission requirements, on LDTs that have historically been marketed without FDA premarket review and oversight. Comments on the Draft Guidances were due on February 2 and those comments are now being considered by the FDA. It is not known when the FDA may issue final Guidances or what form those Guidances may take.

The Framework Draft Guidance states that within six months after the Guidances are finalized, all laboratories will be required to give notice to the FDA and provide basic information concerning the nature of the LDTs offered. The FDA will then begin a phased review of the LDTs available, based on the risk associated with the test. For the highest risk LDTs, which the FDA classifies as Class III devices, the Framework Draft Guidance states that the FDA will begin to require premarket review within 12 months after the Guidance is finalized. Other high risk LDTs will be reviewed over the next four years and then lower risk tests, which will be classified as Class II, will be reviewed in the following four to nine years. The Framework Draft Guidance states that FDA expects to issue a separate Guidance describing the criteria for its risk-based classification 18-24 months after the Guidances are finalized. At this time, we cannot predict how our tests would be classified.

If the FDA regulates LDTs as proposed, then it would classify LDTs according to the current system used to regulate medical devices. Under that system, there are three different classes of medical devices, with the requirements becoming more stringent depending on the Class.

If the Guidances are finalized, it could require that we conduct clinical trials in support of a 510(k) submission or PMA application. These trials generally require an effective Investigational Device Exemption from FDA for a specified number of patients, unless the product is exempt from Investigational Device Exemption requirements or deemed a non-significant risk device eligible for more abbreviated Investigational Device Exemption requirements. The Investigational Device Exemption application must be supported by appropriate data, such as animal and laboratory testing results. Clinical trials may begin 30 days after the submission of the Investigational Device Exemption application unless FDA or the appropriate institutional review boards at the clinical trial sites place the trial on clinical hold.

Under the Guidances, LDTs would also be subject to significant post-market requirements as well. After a device is placed on the market, regardless of the classification or pre-market pathway, it remains subject to significant regulatory requirements. Even if regulatory approval or clearance of a medical device is granted, FDA may impose limitations or restrictions on the uses and indications for which the device may be labeled and promoted. Medical devices may be marketed only for the uses and indications for which they are cleared or approved.

Device manufacturers must also establish registration and device listings with FDA. A medical device manufacturer’s manufacturing processes and those of its suppliers are required to comply with the applicable portions of the Quality Systems Regulations, which cover the methods and documentation of the design, testing, production, processes, controls, quality assurance, labeling, packaging and shipping of medical devices. Domestic facility records and manufacturing processes are subject to periodic unscheduled inspections by FDA. FDA also may inspect foreign facilities that export products to the United States.

Failure to comply with applicable regulatory requirements can result in enforcement action by FDA, which may include any of the following sanctions: warning letters, fines, injunctions, civil or criminal penalties, recall or seizure of current or future products, operating restrictions, partial suspension or total shutdown of production, denial of 510(k) clearance or PMA applications for new products, or challenges to existing 510(k) clearances or PMA applications.

We cannot provide any assurance that FDA regulation, including pre-market review, will not be required in the future for our tests, whether through additional guidance issued by FDA, new enforcement policies adopted by FDA or new legislation enacted by Congress. We believe it is possible that legislation will be enacted into law or guidance could be issued by FDA

49

which may result in increased regulatory burdens for us to continue to offer our tests or to develop and introduce new tests. Given the attention Congress continues to give to these issues, legislation affecting this area may be enacted into law and may result in increased regulatory burdens on us as we continue to offer our tests and to develop and introduce new tests.

In addition, the Secretary of the Department of Health and Human Services requested that its Advisory Committee on Genetics, Health and Society make recommendations about the oversight of genetic testing. A final report was published in April 2008. If the report’s recommendations for increased oversight of genetic testing were to result in further regulatory burdens, they could negatively affect our business and delay the commercialization of tests in development.

The requirement of pre-market review could negatively affect our business until such review is completed and clearance to market or approval is obtained. FDA could require that we stop selling our tests pending pre-market clearance or approval. If FDA allows our tests to remain on the market but there is uncertainty about our tests, if they are labeled investigational by FDA or if labeling claims FDA allows us to make are very limited, orders or reimbursement may decline. The regulatory approval process may involve, among other things, successfully completing additional clinical trials and making a 510(k) submission, or filing a pre-market approval application with FDA. If FDA requires pre-market review, our tests may not be cleared or approved on a timely basis, if at all. We may also decide voluntarily to pursue FDA pre-market review of our tests if we determine that doing so would be appropriate.

Additionally, should future regulatory actions affect any of the reagents we obtain from vendors and use in conducting our tests, our business could be adversely affected in the form of increased costs of testing or delays, limits or prohibitions on the purchase of reagents necessary to perform our testing.

If we were required to conduct additional clinical trials prior to continuing to offer our proprietary genetic-based tests or any other tests that we may develop as LDTs, those trials could lead to delays or failure to obtain necessary regulatory approval, which could cause significant delays in commercializing any future products and harm our ability to achieve sustained profitability.

If FDA decides to require that we obtain clearance or approvals to commercialize our proprietary genetic-based tests, we may be required to conduct additional pre-market clinical testing prior to submitting a regulatory notification or application for commercial sales. In addition, as part of our long-term strategy we plan to seek FDA clearance or approval so we can sell our proprietary tests outside our laboratory; however, we need to conduct additional clinical validation activities on our proprietary tests before we can submit an application for FDA approval or clearance. Clinical trials must be conducted in compliance with FDA regulations or FDA may take enforcement action or reject the data. The data collected from these clinical trials may ultimately be used to support market clearance or approval for our tests. Once commenced, we believe it would likely take two years or more to conduct the studies and trials necessary to obtain approval from FDA to commercially launch any of our proprietary microarrays outside of our clinical laboratory. Even if our clinical trials are completed as planned, we cannot be certain that their results will support our test claims or that FDA or foreign authorities will agree with our conclusions regarding our test results. Success in early clinical trials does not ensure that later clinical trials will be successful, and we cannot be sure that the later trials will replicate the results of prior trials and studies. If we are required to conduct pre-market clinical trials, whether using prospectively acquired samples or archival samples, delays in the commencement or completion of clinical testing could significantly increase our test development costs and delay commercialization. Many of the factors that may cause or lead to a delay in the commencement or completion of clinical trials may also ultimately lead to delay or denial of regulatory clearance or approval. The commencement of clinical trials may be delayed due to insufficient patient enrollment, which is a function of many factors, including the size of the patient population, the nature of the protocol, the proximity of patients to clinical sites and the eligibility criteria for the clinical trial. Moreover, the clinical trial process may fail to demonstrate that our tests are effective for the proposed indicated uses, which could cause us to abandon a test candidate and may delay development of other tests.

We may find it necessary to engage contract research organizations to perform data collection and analysis and other aspects of our clinical trials, which might increase the cost and complexity of our trials. We may also depend on clinical investigators, medical institutions and contract research organizations to perform the trials properly. If these parties do not successfully carry out their contractual duties or obligations or meet expected deadlines, or if the quality, completeness or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols or for other reasons, our clinical trials may have to be extended, delayed or terminated. Many of these factors would be beyond our control. We may not be able to enter into replacement arrangements without undue delays or considerable expenditures. If there are delays in testing or approvals as a result of the failure to perform by third parties, our research and development costs would increase, and we may not be able to obtain regulatory clearance or approval for our tests. In addition, we may not be able to establish or maintain relationships with these parties on favorable terms, if at all. Each of these outcomes would harm our ability to market our tests or to achieve sustained profitability.

50

We are subject to federal and state healthcare fraud and abuse laws and regulations and could face substantial penalties if we are unable to fully comply with such laws.

We are subject to health care fraud and abuse regulation and enforcement by both the federal government and the states in which we conduct our business. These health care laws and regulations include, for example:

• the federal Anti-kickback Statute, which prohibits, among other things, persons or entities from soliciting, receiving, offering or providing remuneration, directly or indirectly, in return for or to induce either the referral of an individual for, or the purchase order or recommendation of, any item or services for which payment may be made under a federal health care program such as the Medicare and Medicaid programs;

• the federal physician self-referral prohibition, commonly known as the Stark Law, which prohibits physicians from referring Medicare or Medicaid patients to providers of “designated health services” with whom the physician or a member of the physician’s immediate family has an ownership interest or compensation arrangement, unless a statutory or regulatory exception applies;

• the federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), which established federal crimes for knowingly and willfully executing a scheme to defraud any health care benefit program or making false statements in connection with the delivery of or payment for health care benefits, items or services;

• federal false claims laws, which, prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third-party payors that are false or fraudulent, and which may apply to entities like us to the extent that our interactions with customers may affect their billing or coding practices; and

• state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws, which may apply to items or services reimbursed by any third-party payor, including commercial insurers.

We have adopted policies and procedures designed to comply with these laws, including policies and procedures relating to financial arrangements between us and physicians who refer patients to us. In the ordinary course of our business, we conduct internal reviews of our compliance with these laws. Our compliance is also subject to governmental review. The government alleged that we engaged in improper billing practices in the past and we may be the subject of such allegations in the future as the growth of our business and sales organization may increase the potential of violating these laws or our internal policies and procedures. See the section entitled “Legal Proceedings” for a detailed description of the government’s prior allegations. The risk of our being found in violation of these laws and regulations is further increased by the fact that many of them have not been fully interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of interpretations. Further, the PPACA, among other things, amends the intent requirement of the federal anti-kickback and criminal health care fraud statutes. A person or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the government may assert that a claim including items or services resulting from a violation of the federal anti-kickback statute constitutes a false or fraudulent claim for purposes of the false claims statutes. Any action brought against us for violation of these laws or regulations, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s 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 any applicable penalty associated with the violation, including civil and criminal penalties, damages and fines, and/or exclusion from participation in Medicare, Medi-Cal or other state or federal health care programs, we could be required to refund payments received by us, and we could be required to curtail or cease our operations. Any of the foregoing consequences could seriously harm our business and our financial results.

We are required to comply with laws governing the transmission, security and privacy of health information that require significant compliance costs, and any failure to comply with these laws could result in material criminal and civil penalties.

Under the administrative simplification provisions of HIPAA, the U.S. Department of Health and Human Services has issued regulations which establish uniform standards governing the conduct of certain electronic health care transactions and protecting the privacy and security of Protected Health Information used or disclosed by health care providers and other covered entities. Three principal regulations with which we are currently required to comply have been issued in final form under HIPAA: privacy regulations, security regulations and standards for electronic transactions.

The privacy regulations cover the use and disclosure of Protected Health Information by health care providers. It also sets forth certain rights that an individual has with respect to his or her Protected Health Information maintained by a health care provider, including the right to access or amend certain records containing Protected Health Information or to request restrictions on the use or disclosure of Protected Health Information. We have also implemented policies, procedures and standards to comply appropriately with the final HIPAA security regulations, which establish requirements for safeguarding the confidentiality, integrity and availability of Protected Health Information, which is electronically transmitted or electronically stored. The HIPAA privacy and security regulations establish a uniform federal “floor” and do not supersede state laws that are

51

more stringent or provide individuals with greater rights with respect to the privacy or security of, and access to, their records containing Protected Health Information. As a result, we are required to comply with both HIPAA privacy regulations and varying state privacy and security laws. Moreover, the Health Information Technology for Economic and Clinical Health Act (“HITECH”), among other things, established certain health information security breach notification requirements. A covered entity must notify any individual whose protected health information is breached.

These laws contain significant fines and other penalties for wrongful use or disclosure of Protected Health Information. We have implemented practices and procedures to meet the requirements of the HIPAA privacy regulations and state privacy laws. In addition, we are in the process of taking necessary steps to comply with HIPAA’s standards for electronic transactions, which establish standards for common health care transactions. Given the complexity of the HIPAA, HITECH and state privacy restrictions, the possibility that the regulations may change, and the fact that the regulations are subject to changing and potentially conflicting interpretation, our ability to comply with the HIPAA, HITECH and state privacy requirements is uncertain and the costs of compliance are significant. To the extent that we submit electronic health care claims and payment transactions that do not comply with the electronic data transmission standards established under HIPAA and HITECH, payments to us may be delayed or denied. Additionally, the costs of complying with any changes to the HIPAA, HITECH and state privacy restrictions may have a negative impact on our operations. We could be subject to criminal penalties and civil sanctions for failing to comply with the HIPAA, HITECH and state privacy restrictions, which could result in the incurrence of significant monetary penalties.

Intellectual Property Risks Related to Our Business

Our rights to use technologies licensed from third parties are not within our control, and we may not be able to sell our products if we lose our existing rights or cannot obtain new rights on reasonable terms.

Our ability to market certain of our tests and services, domestically and/or internationally, is in part derived from licenses to intellectual property which is owned by third parties. As such, we may not be able to continue selling our tests and services if we lose our existing licensed rights or sell new tests and services if we cannot obtain such licensed rights on reasonable terms. In particular, we currently in-license a biomarker from the National Cancer Institute used in our FHACT® probe. Further, we may also need to license other technologies to commercialize future products.

As may be expected, our business may suffer if (i) these licenses terminate; (ii) if the licensors fail to abide by the terms of the license, properly maintain the licensed intellectual property or fail to prevent infringement of such intellectual property by third parties; (iii) if the licensed patents or other intellectual property rights are found to be invalid or (iv) if we are unable to enter into necessary licenses on reasonable terms or at all.

In return for the use of a third-party’s technology, we may agree to pay the licensor royalties based on sales of our products as well as other fees. Such royalties and fees are a component of cost of product revenues and will impact the margins on our tests.

Our collaborators may assert ownership or commercial rights to inventions we develop from our use of the biological materials they provide to us.

We rely on certain collaborators to provide us with tissue samples and biological materials that we use to develop our tests. In some cases we have written agreements with collaborators that may require us to negotiate ownership and commercial rights with the collaborator if our use of such collaborator’s materials results in an invention. Other agreements may limit our use of those materials to research/not for profit use. In other cases, we may not have written agreements, or the written agreements we have may not clearly deal with intellectual property rights. If we cannot successfully negotiate sufficient ownership and commercial rights to the inventions that result from our use of a collaborator’s materials where required, or if disputes otherwise arise with respect to the intellectual property developed with the use of a collaborator’s samples, we may be limited in our ability to capitalize on the market potential of these inventions.

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

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

In particular, the National Cancer Institute and the National Institutes of Health, each of which administered grant monies to us, technically retain the right to require us, under certain specific circumstances, to grant the U.S. government either a nonexclusive, partially exclusive, or exclusive license to the patented invention in any field of use, upon terms that are

52

reasonable for a particular situation. Circumstances that trigger march-in rights include, for example, failure to take, within a reasonable time, effective steps to achieve practical application of the invention in a field of use, failure to satisfy the health and safety needs of the public, and failure to meet requirements of public use specified by federal regulations. The National Cancer Institute and the National Institutes of Health can elect to exercise these march-in rights on their own initiative or at the request of a third-party.

If we are unable to maintain intellectual property protection, our competitive position could be harmed.

Our ability to protect our proprietary discoveries and technologies affects our ability to compete and to achieve sustained profitability. Currently, we rely on a combination of U.S. and foreign patents and patent applications, copyrights, trademarks and trademark applications, confidentiality or non-disclosure agreements, material transfer agreements, licenses, work-for-hire agreements and invention assignment agreements to protect our intellectual property rights. We also maintain as trade secrets certain company know-how and technological innovations designed to provide us with a competitive advantage in the marketplace. Currently, including both U.S. and foreign patent applications, we have only two issued U.S. patents and twelve pending patent applications relating to various aspects of our technology. While we intend to pursue additional patent applications, it is possible that our pending patent applications and any future applications may not result in issued patents. Even if patents are issued, third parties may independently develop similar or competing technology that avoids our patents. Further, we cannot be certain that the steps we have taken will prevent the misappropriation of our trade secrets and other confidential information and technology, particularly in foreign countries where we do not have intellectual property rights.

From time to time the U.S. Supreme Court, other federal courts, the U.S. Congress or the U.S. Patent and Trademark Office (“USPTO”) may change the standards of patentability. Any such changes could have a negative impact on our business. For instance, on October 30, 2008, the Court of Appeals for the Federal Circuit issued a decision that methods or processes cannot be patented unless they are tied to a machine or involve a physical transformation. The U.S. Supreme Court later reversed that decision in Bilski v. Kappos, finding that the “machine-or-transformation” test is not the only test for determining patent eligibility. The Court, however, declined to specify how and when processes are patentable. Most recently, on March 20, 2012, in the case Mayo v. Prometheus, the U.S. Supreme Court reversed the Federal Circuit’s application of Bilski and invalidated a patent focused on a diagnostic process because the patent claim embodied a law of nature. On July 3, 2012, the USPTO issued its Interim Guidelines for Subject Matter Eligibility Analysis of Process Claims Involving Laws of Nature in view of the Prometheus decision. It remains to be seen how these guidelines play out in the actual prosecution of diagnostic claims. Similarly, it remains to be seen lower courts will interpret the Prometheus decision. Some aspects of our technology involve processes that may be subject to this evolving standard, and we cannot guarantee that any of our pending process claims will be patentable as a result of such evolving standards.

The U.S. Supreme Court’s June 14, 2013 decision in Association for Molecular Pathology v. Myriad will likely have an impact on the entire biotechnology industry. Specifically, the case involved certain of Myriad Genetics, Inc.’s U.S. patents related to the breast cancer susceptibility genes BRCA1 and BRCA2. Plaintiffs asserted that the breast cancer genes were not patentable subject matter. The Supreme Court unanimously held that the isolated form of naturally occurring DNA molecules does not rise to the level of patent-eligible subject matter. But the Court also held that claims directed to complementary DNA (cDNA) molecules were patent-eligible because cDNA is not naturally occurring. The Supreme Court focused on the informational content of the isolated DNA and determined that the information contained in the isolated DNA molecule was not markedly different from that naturally found in the human chromosome. Yet, in holding isolated cDNA molecules patent-eligible, the Court recognized the differences between human chromosomal DNA and the corresponding cDNA. Because the non-coding regions of naturally occurring chromosomal DNA have been removed in cDNA, the Court accepted that cDNA is not a product of nature and, therefore, is patent-eligible subject matter.

It does not appear that the Supreme Court’s ruling in Myriad will adversely affect our current patent portfolio which, unlike the claims at issue in Myriad, centers on algorithmic methods associating chromosomal markers to specific clinical end-points. Nevertheless, we of course need to remain mindful that this is an evolving area of law.

In addition, on February 5, 2010, the Secretary’s Advisory Committee on Genetics, Health and Society voted to approve a report entitled “Gene Patents and Licensing Practices and Their Impact on Patient Access to Genetic Tests.” That report defines “patent claims on genes” broadly to include claims to isolated nucleic acid molecules as well as methods of detecting particular sequences or mutations. The report also contains six recommendations, including the creation of an exemption from liability for infringement of patent claims on genes for anyone making, using, ordering, offering for sale or selling a test developed under the patent for patient care purposes, or for anyone using the patent-protected genes in the pursuit of research. The report also recommended that the Secretary should explore, identify and implement mechanisms that will encourage more voluntary adherence to current guidelines that promote nonexclusive in-licensing of diagnostic genetic and genomic technologies. It is unclear whether the U.S. Department of Health and Human Services will act upon these recommendations, or if the

53

recommendations would result in a change in law or process that could negatively impact our patent portfolio or future research and development efforts.

We may face intellectual property infringement claims that could be time-consuming and costly to defend, and could result in our loss of significant rights and the assessment of treble damages.

From time to time we may face intellectual property infringement (or misappropriation) claims from third parties. Some of these claims may lead to litigation. The outcome of any such litigation can never be guaranteed, and an adverse outcome could affect us negatively. For example, were a third-party to succeed on an infringement claim against us, we may be required to pay substantial damages (including up to treble damages if such infringement were found to be willful). In addition, we could face an injunction, barring us from conducting the allegedly infringing activity. The outcome of the litigation could require us to enter into a license agreement which may not be pursuant to acceptable or commercially reasonable or practical terms or which may not be available at all. It is also possible that an adverse finding of infringement against us may require us to dedicate substantial resources and time in developing non-infringing alternatives, which may or may not be possible. In the case of diagnostic tests, we would also need to include non-infringing technologies which would require us to re-validate our tests. Any such re-validation, in addition to being costly and time consuming, may be unsuccessful.

Finally, we may initiate claims to assert or defend our own intellectual property against third parties. Any intellectual property litigation, irrespective of whether we are the plaintiff or the defendant, and regardless of the outcome, is expensive and time-consuming, and could divert our management’s attention from our business and negatively affect our operating results or financial condition.

Risks relating to our International Operations

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

Our business strategy incorporates international expansion, including our recent acquisitions which have provided us with facilities in India and China, and the possibility of establishing and maintaining clinician marketing and education capabilities in other locations outside of the United States and expanding our relationships with distributors and manufacturers. Doing business internationally involves a number of risks, including:

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

• failure by us or our distributors to obtain regulatory approvals for the sale or use of our tests in various countries, including failure to achieve “CE Marking”, a conformity mark which is required to market in vitro diagnostic medical devices in the European Economic Area and which is broadly accepted in other international markets;

• difficulties in managing foreign operations;

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

• logistics and regulations associated with shipping tissue samples, including infrastructure conditions and transportation delays;

• limits on our ability to penetrate international markets if our diagnostic tests cannot be processed by an appropriately qualified local laboratory;

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

• reduced protection for intellectual property rights;

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

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

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

Our operations are subject to risks associated with emerging markets, including China and India.

Emerging markets are a significant focus of our growth strategy. The developing nature of these markets presents several risks, including deterioration of social, political, labor, or economic conditions in a country or region, and difficulties in staffing and managing foreign operations. Perceived risks associated with investing in emerging markets such as China and India, or a general disruption in the development of such markets could materially and adversely affect our business, operating results and financial condition.

54

With the completion of the Gentris acquisition, a portion of our assets and operations are located in China and we are subject to regulatory, economic, political and other uncertainties in China.

The Chinese government has the ability to exercise significant influence and control over our operations in China. In recent years, the Chinese government has implemented measures for economic reform, the reduction of state ownership of productive assets and the establishment of corporate governance practices in business enterprises. However, many productive assets in China are still owned by the Chinese government. In addition, the government continues to play a significant role in regulating industrial development by imposing business regulations. It also exercises significant control over the country’s economic growth through the allocation of resources, controlling payment of foreign currency-denominated obligations, setting monetary policy and providing preferential treatment to particular industries or companies.

There can be no assurance that China’s economic, political or legal systems will not develop in a way that becomes detrimental to our business, results of operations and financial condition. Our activities may be materially and adversely affected by changes in China’s economic and social conditions and by changes in the policies of the government, such as measures to control inflation, changes in the rates or method of taxation and the imposition of additional restrictions on currency conversion.

Additional factors that we may experience in connection with having operations in China or other foreign countries that may adversely affect our business and results of operations include:

• our inability to enforce or obtain a remedy under any material agreements;

• Chinese restrictions on foreign investment that could impair our ability to conduct our business or acquire or contract with other entities in the future;

• restrictions on currency exchange that may limit our ability to use cash flow most effectively or to repatriate our investment;

• fluctuations in currency values;

• cultural, language and managerial differences that may reduce our overall performance; and

• political instability.

With the completion of the BioServe acquisition a portion of our assets and operations are located in India and we are subject to regulatory, economic, political and other uncertainties in India.

In August 2014 we acquired BioServe a leading genomic service and next-generation sequencing company founded in 2002 serving both the research and clinical markets and based in Hyderabad, India. In the past, the Indian economy has experienced many of the problems that commonly confront the economies of developing countries, including high inflation, erratic gross domestic product growth and shortages of foreign exchange. The Indian government has exercised, and continues to exercise, significant influence over many aspects of the Indian economy through the allocation of resources, controlling payment of foreign currency-denominated obligations, setting monetary policy and providing preferential treatment to particular industries, and Indian government actions concerning the economy could have a material adverse effect on private sector entities like us.

India has experienced significant economic growth over the last several years, but faces major challenges in sustaining that growth in the years ahead. These challenges include the need for substantial infrastructure development. India has also recently experienced civil unrest and terrorism and has been involved in conflicts with neighboring countries. In recent years, there have been military confrontations between India and Pakistan that have occurred in the region of Kashmir and along the India-Pakistan border. If India becomes engaged in armed hostilities, particularly if these hostilities are protracted or involve the threat of or use of weapons of mass destruction, it is likely that our operations would be materially adversely affected.

Our financial performance may be adversely affected by general economic conditions and economic and fiscal policy in India, including changes in exchange rates and controls, interest rates and taxation policies, as well as social stability and political, economic or diplomatic developments affecting India in the future.

Some of our contract manufacturers and distributors are located outside of the United States, which may subject us to increased complexity and costs.

We rely on manufacturing facilities located outside the United States for our FHACT® probes, particularly in India. We also utilize distributors to sell FHACT® probes outside the United States. Our FHACT® probe manufacturing and international sales may be subject to certain risks, including:

• difficulty in obtaining, maintaining or enforcing intellectual property rights in some countries;

• local business and cultural factors that differ from our normal standards and practices;

• foreign currency exchange fluctuations;

55

• different regulatory requirements;

• impediments to the flow of foreign exchange capital payments and receipts due to exchange controls instituted by certain foreign governments and the fact that local currencies of some countries are not freely convertible;

• geopolitical and economic instability and military conflicts;

• difficulties in managing international distributors;

• burdens of complying with a variety of foreign laws and treaties and changes in local laws and regulations, including tax laws;

• difficulty in enforcing agreements, judgments and arbitration awards in foreign jurisdictions; and

• adverse economic conditions in any jurisdiction.

Our operating results may be adversely affected by fluctuations in foreign currency exchange rates and restrictions on the deployment of cash across our global operations.

Although we report our operating results in U.S. dollars, a portion of our revenues and expenses are or will be denominated in currencies other than the U.S. dollar. Fluctuations in foreign currency exchange rates can have a number of adverse effects on us. Because our consolidated financial statements are presented in U.S. dollars, we must translate revenues, expenses and income, as well as assets and liabilities, into U.S. dollars at exchange rates in effect during or at the end of each reporting period. Therefore, changes in the value of the U.S. dollar against other currencies will affect our revenues, income from operations, other income (expense), net and the value of balance sheet items originally denominated in other currencies. There is no guarantee that our financial results will not be adversely affected by currency exchange rate fluctuations. In addition, in some countries we could be subject to strict restrictions on the movement of cash and the exchange of foreign currencies, which could limit our ability to use these funds across our global operations.

We could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act and other worldwide anti-bribery laws.

The FCPA and anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments for the purpose of obtaining or retaining business or other commercial advantage. Our policies mandate compliance with these anti-bribery laws, which often carry substantial penalties, including criminal and civil fines, potential loss of export licenses, possible suspension of the ability to do business with the federal government, denial of government reimbursement for products and exclusion from participation in government healthcare programs. We operate in jurisdictions such as India and China that have experienced governmental and private sector corruption to some degree, and, in certain circumstances, strict compliance with anti-bribery laws may conflict with certain local customs and practices. We cannot assure that our internal control policies and procedures always will protect us from reckless or other inappropriate acts committed by our affiliates, employees or agents. Violations of these laws, or allegations of such violations, could have a material adverse effect on our business, financial position and results of operations.

Risks Relating to Our Common Stock

There has been a limited trading market for our common stock.

We only recently received approval to list our common stock on The NASDAQ Capital Market. Prior to August 2013, our common stock had been quoted on the OTCQB, and prior to our initial public offering in April 2013, there was no trading activity in our common stock. Although the NASDAQ listing improved the liquidity of our common stock, such listing has been of limited duration and no assurance can be given that recent levels of trading activity will continue. A lack of an active market may impair the ability of our stockholders to sell shares at the time they wish to sell them or at a price that they consider reasonable. The lack of an active market may also reduce the fair market value of our shares. An inactive market may also impair our ability to raise capital by selling shares of capital stock and may impair our ability to acquire other companies or technologies by using our common stock as consideration.

The price of our common stock may be volatile, and the market price of our common stock may decrease.

Our stock price per share may vary from time to time. Even if an active market for our stock continues, our stock price nevertheless may be volatile. Market prices for securities of early-stage life sciences companies have historically been particularly volatile. The factors that may cause the market price of our common stock to fluctuate include, but are not limited to:

• progress, or lack of progress, in developing and commercializing our proprietary tests;

56

• favorable or unfavorable decisions about our tests or services from government regulators, insurance companies or other third-party payors;

• our ability to recruit and retain qualified regulatory and research and development personnel;

• changes in investors’ and securities analysts’ perception of the business risks and conditions of our business;

• changes in our relationship with key collaborators;

• changes in the market valuation or earnings of our competitors or companies viewed as similar to us;

• changes in key personnel;

• depth of the trading market in our common stock;

• termination of the lock-up agreements or other restrictions on the ability of persons who held our stock prior to our initial public offering to sell shares;

• changes in our capital structure, such as future issuances of securities or the incurrence of additional debt;

• the granting or exercise of employee stock options or other equity awards;

• realization of any of the risks described under this section entitled “Risk Factors”; and

• general market and economic conditions.

In addition, the equity markets have experienced significant price and volume fluctuations that have affected the market prices for the securities of newly public companies for a number of reasons, including reasons that may be unrelated to our business or operating performance. These broad market fluctuations may result in a material decline in the market price of our common stock and you may not be able to sell your shares at prices you deem acceptable. In the past, following periods of volatility in the equity markets, securities class action lawsuits have been instituted against public companies. Such litigation, if instituted against us, could result in substantial cost and the diversion of management attention.

Our stockholders may be diluted by exercises of outstanding options and warrants.

As of December 31, 2014, we had outstanding options to purchase an aggregate of 1,839,458 shares of our common stock at a weighted average exercise price of $10.58 per share and warrants to purchase an aggregate of 1,136,078 shares of our common stock at a weighted average exercise price of $13.47 per share. The exercise of such outstanding options and warrants will result in dilution of the value of our shares.

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

Securities research analysts, including those affiliated with our underwriters, establish and publish their own periodic projections for our business. These projections may vary widely from one another and may not accurately predict the results we actually achieve. Our stock price may decline if our actual results do not match securities research analysts’ projections. Similarly, if one or more of the analysts who writes reports on us downgrades our stock or publishes inaccurate or unfavorable research about our business, our stock price could decline. If one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, our stock price or trading volume could decline. While we expect securities research analyst coverage, if no securities or industry analysts begin to cover us, the trading price for our stock and the trading volume could be adversely affected.

Our directors and executive officers have substantial influence over us and could delay or prevent a change in corporate control.

Our directors and executive officers, together with their affiliates, beneficially own approximately 31.2% of our outstanding common stock, based on the number of shares outstanding on December 31, 2014. These stockholders, acting together, have significant influence over the outcome of matters submitted to our stockholders for approval, including the election of directors and any merger, consolidation or sale of all or substantially all of our assets. In addition, these stockholders, acting together, have significant influence over our management and affairs. Accordingly, this concentration of ownership might harm the market price of our common stock by:

• delaying, deferring or preventing a change in control;

• impeding a merger, consolidation, takeover or other business combination involving us; or

• discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of us.

57

We are an “emerging growth company,” and any decision on our part to comply only with certain reduced disclosure requirements applicable to “emerging growth companies” could make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the JOBS Act, and, for as long as we continue to be an “emerging growth company,” we intend to take advantage of exemptions from various reporting requirements applicable to other public companies but not to “emerging growth companies,” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as discussed above, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. We could be an “emerging growth company” for up to five years, or until the earliest of (i) the last day of the first fiscal year in which our annual gross revenues exceed $1 billion, (ii) the date that we become a “large accelerated filer” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, which would occur if the market value of our common stock that is held by non-affiliates exceeds $700 million as of the last business day of our most recently completed second fiscal quarter, or (iii) the date on which we have issued more than $1 billion in non-convertible debt during the preceding three year period. We have irrevocably chosen to “opt out” of the extended transition periods available under the JOBS Act for complying with new or revised accounting standards. We intend to take advantage of certain exemptions from various reporting requirements including, but not limited to, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved, and if we do take advantage of these exemptions, we cannot predict if investors will find our common stock less attractive as a result. If some investors find our common stock less attractive as a result of any choices to take advantage of these reduced disclosure obligations, there may be a less active trading market for our common stock and our stock price may be more volatile.

We are incurring significantly increased costs and devote substantial management time as a result of operating as a public company particularly after we are no longer an “emerging growth company.”

As a public company and particularly after we cease to be an “emerging growth company”, we are incurring significant legal, accounting and other expenses that we did not incur as a private company and which may increase after we are no longer an "emerging growth company." For example, in addition to being required to comply with certain requirements of the Sarbanes-Oxley Act of 2002, we will be required to comply with certain requirements of the Dodd Frank Wall Street Reform and Consumer Protection Act, as well as rules and regulations subsequently implemented by the SEC, including the establishment and maintenance of effective disclosure and financial controls and changes in corporate governance practices. We expect that compliance with these requirements will increase our legal and financial compliance costs and will make some activities more time consuming and costly. In addition, we expect that our management and other personnel will need to divert attention from operational and other business matters to devote substantial time to these public company requirements.

The Sarbanes-Oxley Act requires, among other things, that we maintain effective internal control over financial reporting and disclosure controls and procedures. In particular, we must perform system and process evaluation and testing of our internal control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act. In addition, after we are no longer an “emerging growth company”, we will be required to have our independent registered public accounting firm attest to the effectiveness of our internal control over financial reporting. Our compliance with Section 404 of the Sarbanes-Oxley Act, as applicable, requires us to incur substantial accounting expense and expend significant management efforts. We currently do not have an internal audit group, and we will need to continue to hire additional accounting and financial staff with appropriate public company experience and technical accounting knowledge. If we or our independent registered public accounting firm identify deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the market price of our stock could decline and we could be subject to sanctions or investigations by the NASDAQ, the SEC or other regulatory authorities, which would require additional financial and management resources.

Our ability to successfully implement our business plan and comply with Section 404, as applicable, requires us to be able to prepare timely and accurate financial statements. We expect that we will need to continue to improve existing, and implement new operational and financial systems, procedures and controls to manage our business effectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations to suffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls from our auditors as required under Section 404 of the Sarbanes-Oxley Act. If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results, and current and potential stockholders may lose confidence in our financial reporting. This, in turn, could have an adverse impact on trading prices for our common stock, and could adversely affect our ability to access the capital markets.

58

Anti-takeover provisions of our certificate of incorporation, our bylaws and Delaware law could make an acquisition of us, which may be beneficial to our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove the current members of our board and management.

Certain provisions of our amended and restated certificate of incorporation and bylaws could discourage, delay or prevent a merger, acquisition or other change of control that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares. Furthermore, these provisions could prevent or frustrate attempts by our stockholders to replace or remove members of our board of directors. These provisions also could limit the price that investors might be willing to pay in the future for our common stock, thereby depressing the market price of our common stock. Stockholders who wish to participate in these transactions may not have the opportunity to do so. These provisions, among other things:

• allow the authorized number of directors to be changed only by resolution of our board of directors;

• authorize our board of directors to issue, without stockholder approval, preferred stock, the rights of which will be determined at the discretion of the board of directors and that, if issued, could operate as a “poison pill” to dilute the stock ownership of a potential hostile acquirer to prevent an acquisition that our board of directors does not approve;

• establish advance notice requirements for stockholder nominations to our board of directors or for stockholder proposals that can be acted on at stockholder meetings; and

• limit who may call a stockholder meeting.

In addition, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, or DGCL, which may, unless certain criteria are met, prohibit large stockholders, in particular those owning 15% or more of the voting rights on our common stock, from merging or combining with us for a prescribed period of time.

Because we do not expect to pay cash dividends for the foreseeable future, you must rely on appreciation of our common stock price for any return on your investment. Even if we change that policy, we may be restricted from paying dividends on our common stock.

We do not intend to pay cash dividends on shares of our common stock for the foreseeable future. Any determination to pay dividends in the future will be at the discretion of our board of directors and will depend upon results of operations, financial performance, contractual restrictions, restrictions imposed by applicable law and other factors our board of directors deems relevant. Accordingly, you will have to rely on capital appreciation, if any, to earn a return on your investment in our common stock. Investors seeking cash dividends in the foreseeable future should not purchase our common stock.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

Our ability to utilize our federal net operating loss, carryforwards and federal tax credits are limited under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended. The limitations apply since we have experienced an “ownership change,” as defined by Section 382, as a result of the Company’s securities offerings. Generally, an ownership change occurs if the percentage of the value of the stock that is owned by one or more direct or indirect “five percent shareholders” changes by more than 50 percentage points over their lowest ownership percentage at any time during the applicable testing period (typically three years). Since we have experienced an “ownership change”, our NOL carryforwards and federal tax credits are subject to limitations as to our ability to utilize them to offset taxable income and related income taxes. In addition, future changes in our stock ownership, which may be outside of our control, may trigger further “ownership changes” which would further limit their utilization. As a result, if we earn net taxable income, our ability to use our pre-change net operating loss carryforwards and other tax attributes to offset United States federal taxable income and related income taxes are subject to limitations, which could potentially result in increased future tax liability to us.

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

If we fail to satisfy the continued listing requirements of The NASDAQ Capital Market, such as the corporate governance requirements or the minimum closing bid price requirement, NASDAQ may take steps to de-list our common stock. Such a de-listing would likely have a negative effect on the price of our common stock and would impair your ability to sell or purchase our common stock when you wish to do so. In the event of a de-listing, we would take actions to restore our compliance with NASDAQ’s listing requirements, but we can provide no assurance that any such action taken by us would allow our common stock to become listed again, stabilize the market price or improve the liquidity of our common stock, prevent our common

59

stock from dropping below the NASDAQ minimum bid price requirement or prevent future non-compliance with NASDAQ’s listing requirements.

PART II

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

Prior to our initial public offering on April 4, 2013, no public trades occurred in our common stock.

Overview

We are an oncology diagnostics company focused on developing, commercializing and providing DNA-based tests and services to improve the personalization of cancer treatment and to better inform biopharmaceutical companies of genomic factors influencing subject responses to therapeutics. Our vision is to become the oncology diagnostics partner for companies and clinicians by participating in the entire care continuum from bench to bedside. We believe the diagnostic industry is undergoing a metamorphosis in its approach to oncology testing, embracing individualized medicine as a means to drive higher standards of patient treatment and disease management. Similarly, biopharma companies are increasingly engaging companies such as ours to provide information on clinical trial participants’ DNA profiles in order to identify genomic variations that may be responsible for differing responses to pharmaceuticals, and particularly to oncology drugs, thereby increasing the efficiency of trials while lowering related costs. We believe tailored therapeutics can revolutionize oncology medicine through DNA-based testing services, enabling physicians and researchers to target the factors that make each patient and disease unique. We have created a unique position in the industry by providing targeted somatic analysis of tumor sample cells alongside germline analysis of an individuals' non-cancerous cells' DNA as we attempt to reach the next milestone in

62

personalized medicine.

Our services are performed at our state-of-the-art laboratories located in New Jersey, North Carolina, Shanghai (China), and Hyderabad, India. Our laboratories comply with the highest regulatory standards as appropriate for the services they deliver including CLIA, CAP, NY State and NABL (India). We have two advisory boards to counsel our scientific and clinical direction. Our Scientific Advisory Board is comprised of preeminent scientists and physicians from the fields of cancer biology, cancer pathology, cancer medicine and molecular genetics.Our Clinical Advisory Board is comprised of clinicians and scientists focused on clinical implementation of our proprietary tests and services and mapping those tests and services to patient needs. Our services are built on a foundation of world-class scientific knowledge and intellectual property in solid and blood-borne cancers, as well as strong academic relationships with major cancer centers such as Memorial Sloan-Kettering, Mayo Clinic, and the National Cancer Institute.

Our clinical offerings include our portfolio of proprietary tests targeting hematological, urogenital and HPV-associated cancers, in conjunction with ancillary non-proprietary tests. Our proprietary tests target cancers that are difficult to prognose and predict treatment outcomes through currently available mainstream techniques. We provide our proprietary tests and services, along with a comprehensive range of non-proprietary oncology-focused tests and laboratory services, to oncologists and pathologists at hospitals, cancer centers, and physician offices, as well as biotech and pharmaceutical companies to support their clinical trials. Our proprietary tests are based principally on our expertise in specific cancer types, test development methodologies and proprietary algorithms correlating genetic events with disease specific information. Our portfolio primarily includes comparative genomic hybridization (CGH) microarrays and next generation sequencing (NGS) panels, and DNA fluorescent in situ hybridization (FISH) probes.

The non-proprietary testing services we offer are focused in part on specific oncology categories where we are developing our proprietary arrays and probe panels. We believe that there is significant synergy in developing and marketing a complete set of tests and services that are disease- and treatment-focused and delivering those tests and services in a comprehensive manner to help with patient management decisions. The insight that we develop in delivering the non-proprietary services are often leveraged in the development of our proprietary programs and now increasingly in the validation of our proprietary programs for clinical use.

We expect to continue to incur significant losses for the near future. We incurred losses of $16.4 million, $12.4 million and $6.7 million for fiscal years ended December 31, 2014, 2013 and 2012, respectively. As of December 31, 2014, we had an accumulated deficit of $77.8 million. 

Key Factors Affecting our Results of Operations and Financial Condition

Our overall long-term growth plan is predicated on our ability to develop and commercialize our proprietary tests, penetrate the BioPharma community to achieve more revenue supporting clinical trials and develop and penetrate the Indian market. In 2014 we acquired Gentris to increase our penetration in the Biopharma space. Our proprietary tests include comparative genomic hybridization (CGH) microarrays and next generation sequencing (NGS) panels, and DNA fluorescent in situ hybridization (FISH) probes. We continue to develop additional proprietary tests. To facilitate market adoption of our proprietary tests, we anticipate having to successfully complete additional studies with clinical samples and publish our results in peer-reviewed scientific journals. Our ability to complete such studies is dependent upon our ability to leverage our collaborative relationships with leading institutions to facilitate our research and obtain data for our quality assurance and test validation efforts.

We believe that the factors discussed in the following paragraphs have had and are expected to continue to have a material impact on our results of operations and financial condition.

Revenues

Our revenue is primarily generated through our Clinical Services and Biopharma Services. Clinical Services can be billed to Medicare, another third party insurer or the referring community hospital or other healthcare facility in accordance with state and federal law. Biopharma Services are billed to the customer directly. We also derive limited revenue from Discovery Services, which are services provided in the development of new testing assays and methods. Discovery Services are billed directly to the customer. Revenue also includes receipts from grants (2013 and 2012 only).

We have historically derived a significant portion of our revenue from a limited number of test ordering sites, although the test ordering sites that generate a significant portion of our revenue have changed from period to period. Our test ordering sites are largely hospitals, cancer centers, reference laboratories and physician offices, as well as biopharmaceutical companies as part of

63

a clinical trial. Oncologists and pathologists at these sites order the tests on behalf of the needs of their oncology patients or as part of a clinical trial sponsored by a biopharmaceutical company in which the patient is being enrolled.

The top five test ordering clients during 2014 and 2013 accounted for 56% and 69%, respectively, of our testing volumes, with 38% and 36%, respectively, of the test volume coming from community hospitals. During the year ended December 31, 2014, two Biopharma clients accounted for approximately 23% and 12%, respectively, of our revenue. During the year ended December 31, 2013 there was one Biopharma client that accounted for approximately 40% of our revenue. The loss of our largest client would materially adversely affect our results of operations, however the loss of any other test ordering client would not materially adversely affect our results of operations.

We receive revenue for our Clinical Services from Medicare, other insurance carriers and other healthcare facilities.  Some of our customers choose, generally at the beginning of our relationship, to pay for laboratory services directly as opposed to having patients (or their insurers) pay for those services and providing us with the patients’ insurance information.  A hospital may elect to be a direct bill customer and pay our bills directly, or may provide us with patient information so that their patients pay our bills, in which case we generally expect payment from their private insurance carrier or Medicare. In a few instances, we have arrangements where a hospital may have two accounts with us, so that certain tests are billed directly to the hospital, and certain tests are billed to and paid by a patient’s insurer. The billing arrangements generally are dictated by our customers and in accordance with state and federal law.

For the year ended December 31, 2014, Medicare accounted for approximately 11% of our total revenue, other insurance accounted for approximately 16% of our total revenue and other healthcare facilities accounted for 16% of our total revenue.   As we expand our portfolio of tests and services, and our sales activities, we expect the percentage of revenue from other healthcare facilities may decrease over the long term.  However, the addition of new customers, particularly a community hospital or other large volume client, could offset this trend seen in prior years. On average, we generate less revenue per test from other healthcare facilities billed directly, than from other insurance payors.  However, we have reduced sales cost associated with direct bill clients as well as significantly reduced collections risk. Typically, we negotiate discounts in the range of 5% to 20% with directly billed healthcare facilities depending on the volume of business.

Cost of Revenues

Our cost of revenues consists principally of internal personnel costs, including stock-based compensation, laboratory consumables, shipping costs, overhead and other direct expenses, such as specimen procurement and third party validation studies. We are pursuing various strategies to reduce and control our cost of revenues, including automating our processes through more efficient technology and attempting to negotiate improved terms with our suppliers. We completed two acquisitions in 2014; Gentris in North Carolina and BioServe in India. With these two acquisitions, we intend to integrate our resources and services in an effort to reduce costs. We will continue to assess how geographic advantage can help us improve our cost structure.

Operating Expenses

We classify our operating expenses into three categories: research and development, sales and marketing, and general and administrative. Our operating expenses principally consist of personnel costs, including stock-based compensation, outside services, laboratory consumables and overhead, development costs, marketing program costs and legal and accounting fees.

Research and Development Expenses. We incur research and development expenses principally in connection with our efforts to develop our proprietary tests. Our primary research and development expenses consist of direct personnel costs, laboratory equipment and consumables and overhead expenses. We anticipate that research and development expenses will increase in the near-term, principally as a result of hiring additional personnel to develop and validate tests in our pipeline and to perform work associated with our research collaborations. In addition, we expect that our costs related to collaborations with research and academic institutions will increase. For example, in 2013, we entered into a joint venture with the Mayo Foundation for Medical Education and Research, with a focus on developing oncology diagnostic services and tests utilizing next generation sequencing. All research and development expenses are charged to operations in the periods they are incurred.

Sales and Marketing Expenses. Our sales and marketing expenses consist principally of personnel and related overhead costs for our sales team and their support personnel, travel and entertainment expenses, and other selling costs including sales collaterals and trade shows. We have started to increase our sales and marketing and clinical efforts since our IPO and we expect our sales and marketing expenses to increase significantly as we expand into new geographies and add new clinical tests and services.

64

General and Administrative Expenses. General and administrative expenses consist principally of personnel-related expenses, professional fees, such as legal, accounting and business consultants, occupancy costs, bad debt and other general expenses. We have incurred increases in our general and administrative expenses and anticipate further increases as we expand our business operations.

Seasonality

Our business experiences decreased demand during spring vacation season, summer months and the December holiday season when patients are less likely to visit their health care providers. We expect this trend in seasonality to continue for the foreseeable future.

Total Revenue	10,199	100	%	6,610	100	%	3,589		54	%

Revenue increased 54%, or $3.6 million, to $10.2 million for the year ended December 31, 2014, from $6.6 million for the year ended December 31, 2013, principally due to the acquisitions of Gentris and BioServe, whose revenue accounted for $3.3 million of the increase. Our average revenue (excluding grant revenue and probe revenue) per test decreased to $550 per test for the year ended December 31, 2014 from $566 per test for the year ended December 31, 2013, principally due to a decrease in the average revenue per test from private insurance carriers and other non-Medicare payors. This was offset by an 11%

65

increase in test volume from 10,771 tests for the year ended December 31, 2013, to 11,912 tests for the year ended December 31, 2014.

Revenue from Biopharma Services increased 112%, or $3.0 million, to $5.6 million for the year ended December 31, 2014, from $2.7 million for the year ended December 31, 2013, principally due to the acquisition of Gentris whose revenue accounted for a $3.1 million increase offset by an $180,000 decrease in legacy Biopharma Services. Revenue from Clinical Services customers increased 21%, or $770,000, to $4.4 million for the year ended December 31, 2014, from $3.7 million for the year ended December 31, 2013, principally due to an increase in test volume. This increase in volume was partially offset by adecrease in average revenue per test. Revenue from Discovery Services, our new line of business, increased $161,000 for the year ended December 31, 2014 representing 2% of total revenue. Revenue from Grants decreased 100%, or $297,000, for the year ended December 31, 2014, due to the completion of all grant activities in the year ended December 31, 2013.

Cost of Revenues

Cost of revenues increased 72%, or $3.5 million, to $8.4 million for the year ended December 31, 2014, from $4.9 million for the year ended December 31, 2013, principally due to the following: Costs of revenue from the acquired businesses of $2.2 million, lab supplies expenses increased by $460,000 or 40% as a result of higher test volumes, shipping costs increased by $300,000 or 130% as a result of higher test volume, outsourcing services increased by $220,000 or 257% as a result of us contracting with select labs to perform some of our tests, and compensation costs increased by $220,000 or 9% as a result of us securing the expertise needed to continue to deliver high quality test results. Overall the cost of revenue did not increase proportionately with revenue, due to the cost of revenue in 2013 being lower in proportion as a result of us performing a large number of tests for a clinical trials client in 2013 and in 2013 there was $297,000 in grant revenues that carried minimal costs, whereas in 2014 there were no grant revenues.

Operating Expenses

Research and Development Expenses. Research and development expenses increased 111%, or $2.4 million, to $4.6 million for the year ended December 31, 2014, from $2.2 million for the year ended December 31, 2013, principally due to the following: Our share of the loss from Oncospire, our joint venture with Mayo Clinic, increased $930,000, as it incurred a full year of research expenses related to the pursuit of developing new clinical tests. (In 2013, the costs associated with our joint venture was $12,000). Compensation costs increased by $793,000 or 88% as a result of us building up our R&D team, and supplies costs increased by $295,000 or 64% as a result of us accelerating the development of our proprietary tests.

Sales and Marketing Expenses. Sales and marketing expenses increased 115%, or $2.1 million, to $3.9 million for the year ended December 31, 2014, from $1.8 million for the year ended December 31, 2013, principally due to the following: Costs from the acquired businesses of $538,000, compensation costs increased by $1.1 million or 86% as a result of us building and developing our team, marketing costs increased by $165,000 or 163% as a result of a concentrated effort to expand our customer base, travel costs increased by $100,000, and stock-based compensation increased by $90,000 due to increases in the number of sales personnel.

General and Administrative Expenses. General and administrative expenses increased 102%, or $6.3 million to $12.4 million for the year ended December 31, 2014, from $6.1 million for the year ended December 31, 2013, principally due to the following: Costs from the acquired businesses of $1.4 million, stock-based compensation increased by $2.5 million, costs associated with being a public company increased by $1.5 million due to higher consulting, legal and insurance expenses, compensation costs increased by $575,000 primarily due to a severance agreement for a former officer, allowance for doubtful accounts increased by $215,000 as we established a reserve for potential uncollectable amounts in our Clinical Services business, professional and consulting fees increased by $120,000, recruiting fee costs increased by $125,000, and travel costs increased by $220,000 as a result of the increased travel related to the acquisitions and our expanded customer base, partially off-set by $618,000 in IPO costs incurred in 2013, which did not recur in 2014.

Interest Income and Expense

Interest expense decreased 83%, or $2.3 million, to $399,000 for the year ended December 31, 2014, from $2.4 million for the year ended December 31, 2013. The decrease is attributable to the conversion of $9.6 million of debt into common stock which occurred concurrently with the closing of our IPO on April 10, 2013 and the repayment of $3.5 million in indebtedness in August 2013.

Debt Conversion Costs

66

On April 10, 2013, we completed our IPO. In connection with the IPO, $9.6 million of debt was converted into common stock at the IPO price of $10.00 per share. In connection with the conversion of debt into common stock, we expensed the applicable remaining debt discounts of $3.5 million, financing fees of $419,000 and a contingently recognizable beneficial conversion feature in the converted debt of $3.0 million, the total of which resulted in a $6.9 million write-off. There were no comparable costs in 2014.

Change in Fair Value of Warrant Liability

The change in the fair market value of our warrant liability resulted in $417,000 in non-cash income for the year ended December 31, 2014, as compared to non-cash income of $4.6 million for the year ended December 31, 2013. The fair market value of these common stock warrants decreased as a consequence of a decrease in our stock price.

Income Taxes

During the year ended December 31, 2014, we received two payments totaling $2.4 million from sales of state NOL’s. During January 2013, we received $664,000 from the sale of state NOL’s.

Year Ended December 31, 2013 and 2012

67

Revenue increased 54%, or $2.3 million, to $6.6 million for the year ended December 31, 2013, from $4.3 million for the year ended December 31, 2012, due to increases in test volume. Our average revenue (excluding grant revenue and probe revenue) per test increased to $566 per test for the year ended December 31, 2013 from $553 per test for the year ended December 31, 2012 principally due to an increase in the average revenue per test for Biopharma Services offset by a decrease in the average revenue per test from private insurance carriers and other non-Medicare payors for Clinical Services. Our test volume increased by 63% to 10,771 tests for the year ended December 31, 2013, from 6,610 tests for the year ended December 31, 2012 principally due to an increase in tests performed for a significant Biopharma client.

Revenue from Biopharma Services increased 358%, or $2.1 million, to $2.7 million for the year ended December 31, 2013, from $578,000 for the year ended December 31, 2012, principally due to an increase in revenue from a significant Biopharma client. Revenue from Biopharma customers as a percentage of total revenue increased to 40% for the year ended December 31, 2013, from 13% for the year ended December 31, 2012. Revenue from Clinical Services increased 16%, or $497,000, to $3.7 million for the year ended December 31, 2013, from $3.2 million for the year ended December 31, 2012, principally due to an increase in testing volume partially offset by a decrease in revenue per test. Revenue from Clinical Services as a percentage of total revenue decreased to 55% of total revenue for the year ended December 31, 2013, from 74% of total revenue for the year ended December 31, 2012. Revenue from Grants decreased 47%, or $260,000, to $297,000 for the year ended December 31, 2013, from $557,000 for the year ended December 31, 2012, principally due to achieving the scheduled milestones for grant drawdowns.

Cost of Revenues

Cost of revenues increased 25%, or $996,000, to $4.9 million for the year ended December 31, 2013, from $3.9 million for the year ended December 31, 2012, principally due to an increase in employee compensation-related expenses of $650,000 resulting from a net increase in headcount and an increase in supply costs of $244,000 as a result in increased testing volumes. However, due to scaling efficiencies associated with performing a large number of tests for a clinical trials client in 2013, costs did not increase proportionately relative to the increase in revenues.

Operating Expenses

Research and Development Expenses. Research and development expenses increased 4%, or $78,000, to $2.2 million for the year ended December 31, 2013, from $2.1 million for the year ended December 31, 2012, principally as a result of an increase in supplies expense of $237,000, and an increase in non-employee stock-based compensation related expenses of $72,000, which were offset by a decrease of $230,000 in employee compensation related expenses as a result of a reduction in stock-based compensation.

Sales and Marketing Expenses. Sales and marketing expenses increased 32%, or $443,000, to $1.8 million for the year ended December 31, 2013, from $1.4 million for the year ended December 31, 2012, principally due to an increase in headcount and compensation-related costs.

General and Administrative Expenses. General and administrative expenses increased 36%, or $1.6 million to $6.1 million for the year ended December 31, 2013, from $4.5 million for the year ended December 31, 2012, principally due to the write-off of $618,000 of deferred IPO costs and an increase of $568,000 in compensation and headcount-related expenses (including IPO bonuses paid in 2013 and stock-based compensation), an increase of $216,000 in insurance costs coincident with the additional risk of a public company, and an increase of $556,000 of professional and consulting fees as a result of being a public company. These increases were partially offset by a decrease of $350,000 related to the cost of a legal settlement in 2012.

Interest Income and Expense

Interest expense decreased 50%, or $2.3 million, to $2.4 million for the year ended December 31, 2013, from $4.7 million for the year ended December 31, 2012. The decrease is attributable to the conversion of $9.6 million of debt into common stock which occurred concurrently with the closing of our IPO on April 10, 2013 and the repayment of $3.5 million in indebtedness in August 2013.

Debt Conversion Costs

On April 10, 2013, we completed our IPO. In connection with the IPO, $9.6 million of debt was converted into common stock at the IPO price of $10.00 per share. In connection with the conversion of debt into common stock, we expensed the applicable remaining debt discounts of $3.5 million, financing fees of $419,000 and a contingently recognizable beneficial conversion feature in the converted debt of $3.0 million, the total of which resulted in a $6.9 million write-off.

Change in Fair Value of Warrant Liability

The change in the fair market value of our warrant liability decreased as a consequence of a decrease in our stock price and resulted in $4.6 million in non-cash income for the year ended December 31, 2013, as compared to non-cash income of $7.5 million for the year ended December 31, 2012. The fair market value of certain of our outstanding common stock warrants, that we are required to account for as liabilities, decreased during the year ended December 31, 2013, principally as the result of a shareholder, Mr. John Pappajohn, limiting certain anti-dilution rights in his warrants to purchase shares of the Company’s common stock, resulting in a lower fair value of the warrant liability and non-cash income during this period. Concurrent with the IPO on April 10, 2013, derivative warrants with a fair value of $7.2 million were reclassified into equity due to the lapsing of anti-dilution provisions in the warrants. Since the re-classification, future changes in the value of these specific warrants are no longer required to be recorded in our financial statements although there are 95,130 warrants that are still subject to future revaluation.

Loss on Debt and Warrant Restructuring

Loss on debt and warrant restructuring was $0, for the year ended December 31, 2013, compared to $1.9 million for the year ended December 31, 2012. In the 2013, there was no debt and warrant restructuring, whereas in 2012, as a result of the restructuring of borrowings under the Restated Credit Agreement associated with our 2012 Convertible Debt Financing Transaction, there was a $1.5 million charge and a $356,000 charge related to the cancellation of certain warrants under the Restated Credit Agreement.

Liquidity and Capital Resources

Sources of Liquidity

Our primary sources of liquidity have been funds generated from our debt financings and equity financings. In addition, we have generated funds from the following sources: (i) cash collections from customers; (ii) cash received from sale of state NOL’s; and (iii) grants from the National Institutes of Health.

During the year ended December 31, 2014, we received two payments totaling $2.4 million from sales of state NOL’s. During January 2013, we received $664,000 from the sale of state NOL’s.

In general, our primary uses of cash are providing for operating expenses, working capital purposes and servicing debt. As of December 31, 2014, we have maximized our borrowings under our revolving credit line of $6.0 million. Our largest source of operating cash flow is cash collections from our customers.

On April 10, 2013, we sold 690,000 shares of common stock at a public offering price of $10.00 per share and completed our initial public offering, or IPO, with net proceeds of $5 million. Upon the closing of the IPO, all shares of our then-outstanding Series A and Series B convertible preferred stock automatically converted into an aggregate of 1,287,325 shares of common stock. Concurrent with the IPO, certain derivative warrants with a fair value of $7.2 million were reclassified into equity due to the lapsing of anti-dilution provisions in the warrants. Also concurrent with the IPO, $9.6 million of debt converted into 963,430 shares of common stock. Refer to Notes 1, 6 and 10 to the Consolidated Financial Statements accompanying this filing.

On August 19, 2013 in our Secondary Offering, or our Secondary Offering, we sold 1,500,000 shares of common stock at a public offering price of $10.00 per share which resulted in gross proceeds of $15.0 million ($13.3 million of net proceeds after offering expenses and underwriting discounts). On September 5, 2013, we sold 105,000 additional common shares pursuant to the underwriter’s partial exercise of the over-allotment option which resulted in gross proceeds of $1.1 million ($947,000 of net proceeds after offering expenses and underwriting discounts). Upon completion of the Secondary Offering we repaid indebtedness in the aggregate principal amount of $3.5 million plus accrued interest to DAM and to one of our directors, Andrew Pecora, and an affiliated company NJCCA, all of which indebtedness was due on August 15, 2013.

On October 28, 2013 in a follow-on public offering, or our Follow-On Offering, we sold 3,286,700 shares of common stock (including the underwriter’s overallotment of 428,700 shares), at a public offering price of $14.00 per share resulting in gross proceeds of $46.0 million (net proceeds of $42.3 million).

Following our IPO, Secondary Offering, Follow-On Offering and the related debt repayments, we have the following credit facility outstanding:

Wells Fargo Line of Credit.

69

At December 31, 2014 and 2013, we have fully utilized a line of credit with Wells Fargo Bank which provides for maximum borrowings of $6 million. On April 1, 2014, the line of credit was extended through April 1, 2016 at a rate of interest equal to the Daily One Month LIBOR rate plus 1.75% (1.91% at December 31, 2014). The facility requires monthly interest payments.

The loan facility is collateralized by $6 million in restricted cash at December 31, 2014 and will remain restricted until such time as it is repaid. Additionally, we are required to maintain limits on capital spending and are restricted as to the amount we may pledge as collateral for additional borrowings from any source.

The line of credit requires the repayment of principal, and any unpaid interest, in a single payment due upon maturity.

Cash Flows

Our net cash flow from operating, investing and financing activities for the periods below were as follows:

	Year Ended
	December 31,
	2014			2013			2012
(in thousands)
Cash provided by (used in):
Operating activities	$	(12,338	)	$	(8,075	)	$	(7,578	)
Investing activities	(11,373		)	(1,399		)	(347		)
Financing activities	(195		)	58,114			6,328
Net increase (decrease) in cash and cash equivalents	$	(23,906	)	$	48,640		$	(1,597	)

We had cash and cash equivalents of $25.6 million at December 31, 2014, $49.5 million at December 31, 2013, and $820,000 at December 31, 2012.

The $23.9 million decrease in cash and cash equivalents for the year ended December 31, 2014, was principally the result of the use of $12.3 million of net cash in operations, restricting $6.0 million to secure a line of credit with Wells Fargo of $6.0 million, payments of $2.9 million for the acquisitions of Gentris and BioServe, payment of $1.0 million to invest in our joint venture with Mayo and the purchase of fixed assets of $1.4 million.

The $48.6 million increase in cash and cash equivalents from December 31, 2012 to December 31, 2013, was principally the result of the receipt of $5.0 million in proceeds received in our IPO, the receipt of $14.2 in net proceeds from our Secondary Offering, and the receipt of $42.3 million in net proceeds from our Follow-On Offering, all of which were offset by $1.0 million paid to invest in our joint venture with Mayo, the repayment of $3.6 million in indebtedness and the use of $8.1 million of net cash in operations.

The $1.6 million decrease in cash and cash equivalents from December 31, 2011, to December 31, 2012, was principally the result of our $7.6 million net cash used in operations, including $1.1 million in cash interest payments, payment of $1.4 million in equity issuance costs, and $162,000 in purchases of fixed assets, offset by $7.8 million in net proceeds from borrowings under new notes payable and warrant exercises.

Cash Used in Operating Activities

Net cash used in operating activities was $12.3 million for the year ended December 31, 2014. We used $13.5 million in net cash to run our core operations, which included $128,000 in cash paid for interest. We incurred additional uses of cash when adjusting for working capital items as follows: a net increase in accounts receivable of $1.4 million; an increase in other current assets of $53,000, which included prepayments for our insurance policies; and a net decrease in accounts payable, accrued expenses and deferred revenue of $ 511,000. All of these uses of cash were partially offset by the receipt of $2.4 million from the sale of certain state NOL carryforwards in January 2014 and December 2014.

Net cash used in operating activities was $8.1 million for the year ended December 31, 2013. We used $7.1 million in net cash to run our core operations, which included $608,000 in cash paid for interest. We incurred additional uses of cash as follows: $731,000 for a net decrease in accounts payable, accrued expenses and deferred revenue; $375,000 to increase other current assets which included prepayments for consumables and other supplies used to run our operations as well as prepayments for our insurance policies, and; accounts receivable increased by $716,000. All of these uses of cash were partially offset by the receipt of $664,000 from the sale of certain state NOL carryforwards in January 2013.

70

Net cash used in operating activities was $7.6 million for the year ended December 31, 2012, consisting primarily of a $6.7 million net loss during the period, which includes $1.1 million in cash interest payments, non-cash income from a change in fair value of warrant liability of $7.5 million, offset by non-cash debt costs of $3.6 million, $1.9 million of non-cash loss on debt and warrant restructuring, and $900,000 in equity and warrant-based non-cash compensatory transactions.

Cash Used in Investing Activities

Net cash used in investing activities was $11.4 million for the year ended December 31, 2014 and principally resulted from an increase in our restricted cash of $6.0 million related to the collateralization of our line of credit with Wells Fargo; cash paid of $2.9 million in the acquisitions of Gentris and BioServe; investment of $1.0 million in our Joint Venture with the Mayo Foundation and purchase of fixed assets of $1.4 million.

Net cash used in investing activities was $1.4 million for the year ended December 31, 2013 and principally resulted from: a $1.0 million payment to Mayo to fund our joint venture; purchases of fixed assets of $257,000; patent application costs of $92,000, and; an increase in our restricted cash related to a $50,000 increase in the Letter of Credit related to our lease. Pursuant to the terms of our lease for our Rutherford facility, we were required to maintain a letter of credit in the amount of $300,000 to use as a guarantee for the security deposit.

Net cash used in investing activities was $348,000 for the year ended December 31, 2012 due to an increase in our restricted cash related to a $50,000 increase in the Letter of Credit related to our lease as well as $135,000 in patent application costs and $162,000 in purchases of fixed assets.

Cash Used/Provided by Financing Activities

Net cash used in financing activities was $195,000 for the year ended December 31, 2014, and primarily resulted from payments on notes payable of $408,000; partially off-set by proceeds received from warrant and option exercises of $257,000.

Net cash provided by financing activities was $58.1 million for the year ended December 31, 2013, and primarily consisted of receipt of $61.5 million in net proceeds raised in our IPO, Secondary Offering and Follow-On Offering offset by the repayment of $3.6 million in indebtedness.

Net cash provided by financing activities was $6.3 million for the year ended December 31, 2012, principally due to our receipt of $7.1 million in net proceeds from various financing transactions and $635,000 in net proceeds from the exercise of certain warrants. We paid $1.4 million in equity issuance costs related to our IPO in the year ended December 31, 2012.

Capital Resources, Acquisitions and Expenditure Requirements

We expect to continue to incur substantial operating losses in the future. It may take several years, if ever, to achieve positive operational cash flow. Until we can generate a sufficient amount of revenue to finance our cash requirements, which we may never do, we will need to continue to raise additional capital to fund our operations.

We also expect to use significant cash to fund acquisitions. On July 16, 2014, we purchased substantially all of the assets of Gentris Corporation, (“Gentris”), with its principal place of business in North Carolina.

The total consideration recorded for the Gentris acquisition is as follows:

	Amount
Cash paid at closing	$	3,250,000
Issuance of 147,843 common shares	1,271,745
Estimated fair value of contingent consideration	293,400
Total Purchase Price	$	4,815,145

The estimated fair value of contingent consideration is a potential earn-out which is payable in cash or shares of our common stock at our option, and is based upon a formula that provides for additional amounts, for revenues of $4.75 million, up to revenues of $8.55 million, plus a potential payment to be made in connection with the termination of a biorepository relationship with Gentris, based upon exit fees to be received by Gentris. The amounts used in computing the purchase price differ from the amounts in the purchase agreements due to fair value measurement conventions prescribed in accounting standards.

71

On August 18, 2014 we acquired BioServe BioTechnologies (India) Private Limited, an Indian corporation (“BioServe”) for an aggregate purchase price of approximately $1.1 million.

The total consideration recorded for the BioServe acquisition is as follows:

	Amount
Cash paid at closing	$	72,907
Notes payable due 12-18 months after closing	23,708
Notes payable (value of 84,278 common shares)	733,387
Issuance of 31,370 common shares	244,247
Total Purchase Price	$	1,074,249

The amounts used in computing the purchase price differ from the amounts in the purchase agreements due to fair value measurement conventions prescribed in accounting standards.

See Note 1 to the financial statements for additional information regarding the Gentris and BioServe acquisitions.

We believe our cash and cash equivalents are sufficient to satisfy our liquidity requirements at our current level of operations for at least 24 months.

We expect our operating expenses to increase as we continue investing in sales and marketing, research and development and other general and administrative expenses.

Our forecast of the period of time through which our current financial resources will be adequate to support our operations and our expected operating expenses are forward-looking statements and involve risks and uncertainties. Actual results could vary materially and negatively as a result of a number of factors, including:

• our ability to achieve revenue growth;

• our ability to obtain approvals for our new diagnostic tests;

• our ability to execute on our marketing and sales strategy for our genomic tests and gain acceptance of our tests in the market;

• our ability to obtain adequate reimbursement from governmental and other third-party payors for our tests and services;

• the costs, scope, progress, results, timing and outcomes of the clinical trials of our diagnostic tests;

• the costs of operating and enhancing our laboratory facilities;

• the costs for funding the operations we recently acquired and our ability to successfully integrate those operations with and into our own;

• the costs of additional general and administrative personnel;

• the timing of and the costs involved in regulatory compliance. particularly in the regulations change;

• the costs of maintaining, expanding and protecting our intellectual property portfolio, including potential litigation costs and liabilities;

• our ability to manage the costs of manufacturing our NGS panels, microarrays and FHACT® probe;

• our rate of progress in, and cost of research and development activities associated with, products in research and early development;

• the effect of competing technological and market developments;

• costs related to international expansion;

• our ability to secure financing and the amount thereof; and

• other risks discussed in the section entitled “Risk Factors”.

We expect that our operating expenses and capital expenditures will increase in the future as we expand our business and integrate our recent acquisitions. We plan to increase our sales and marketing headcount to promote our new clinical tests and services and to expand into new geographies and to increase our research and development headcount to develop and validate the proprietary tests currently in our pipeline, to expand our pipeline and to perform work associated with our research collaborations. For example, in 2011 we entered into an affiliation agreement to form a joint venture with the Mayo Foundation for Medical Education and Research pursuant to which we made an initial $1.0 million capital contribution in October 2013

72

and $1.0 million in the third quarter of 2014. We currently anticipate that we will make capital contributions of $1.0 million in the second quarter of 2015 and expect to make additional capital contributions of up to $3.0 million over the next eighteen months, subject to the joint venture entity’s achievement of certain operational milestones. Until we can generate a sufficient amount of revenues to finance our cash requirements, which we may never do, we may need to raise additional capital to fund our operations.

We may raise additional capital to fund our current operations, to repay certain outstanding indebtedness and to fund expansion of our business to meet our long-term business objectives through public or private equity offerings, debt financings, borrowings or strategic partnerships coupled with an investment in our company or a combination thereof. If we raise additional funds through the issuance of convertible debt securities, or other debt securities, these securities could be secured and could have rights senior to those of our common stock. In addition, any new debt incurred by the Company could impose covenants that restrict our operations and increase our interest expense. The issuance of any new equity securities will also dilute the interest of our current stockholders. Given the risks associated with our business, including our unprofitable operating history and our ability to develop additional proprietary tests, additional capital may not be available when needed on acceptable terms, or at all. If adequate funds are not available, we will need to curb our expansion plans or limit our research and development activities, which would have a material adverse impact on our business prospects and results of operations.

Future Contractual Obligations

The following table reflects a summary of our estimates of future contractual obligations as of December 31, 2014. The information in the table reflects future unconditional payments and is based on the terms of the relevant agreements, appropriate classification of items under U.S. GAAP as currently in effect and certain assumptions, such as the interest rate on our variable debt that was in effect as of December 31, 2014. Future events could cause actual payments to differ from these amounts.

	Total		Less than 1 Year		2-3 Years		4-5 Years		More than 5 Years
(dollars in thousands)
Principal and interest under notes payable and lines of credit	$	6,143			$	6,143	$	—	$	—
Capital Lease obligations, including interest, for equipment	412		74		136		118		84
Operating lease obligations relating to corporate headquarters and clinical laboratories	3,404		855		1,733		681		135
Total	$	9,959	$	929	$	8,012	$	799	$	219

Income Taxes

Over the past several years we have generated operating losses in all jurisdictions in which we may be subject to income taxes. As a result, we have accumulated significant net operating losses and other deferred tax assets. Because of our history of losses and the uncertainty as to the realization of those deferred tax assets, a full valuation allowance has been recognized. We do not expect to report a benefit related to the deferred tax assets until we have a history of earnings, if ever, that would support the realization of our deferred tax assets.

Off-Balance Sheet Arrangements

Since inception, we have not engaged in any off balance sheet activities as defined in Item 303(a)(4) of Regulation S-K.

Critical Accounting Policies and Significant Judgment and Estimates

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

73

Section 107 of the JOBS Act provides that an “emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. In other words, an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. However, we have chosen to “opt out” of such extended transition period, and as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. Section 107 of the JOBS Act provides that our decision to opt out of the extended transition period for complying with new or revised accounting standards is irrevocable.

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

• Revenue recognition;

• Accounts receivable and bad debts;

• Stock-based compensation; and

• Warrant liability.

To the Board of Directors and Stockholders

Cancer Genetics, Inc. and Subsidiaries

We have audited the accompanying consolidated balance sheets of Cancer Genetics, Inc. and subsidiaries as of December 31, 2014 and 2013, and the related consolidated statements of operations, changes in stockholders’ equity (deficit), and cash flows for each of the three years ended December 31, 2014, 2013 and 2012. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, 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. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Cancer Genetics, Inc. and subsidiaries as of December 31, 2014 and 2013, and the results of their operations and their cash flows for each of the three years ended December 31, 2014, 2013 and 2012 in conformity with U.S. generally accepted accounting principles.

CANCER GENETICS, INC. AND SUBSIDIARY

Notes to Consolidated Financial Statements

Note 1. Organization, Acquisitions, Description of Business, Reverse Stock Split and Charter Amendment

We are an oncology diagnostics company focused on developing, commercializing and providing DNA-based tests and services to improve the personalization of cancer treatment and to better inform biopharmaceutical companies of genomic factors influencing subject responses to therapeutics. Our vision is to become the oncology diagnostics partner for companies and clinicians by participating in the entire care continuum from bench to bedside. We believe the diagnostic industry is undergoing a metamorphosis in its approach to oncology testing, embracing individualized medicine as a means to drive higher standards of patient treatment and disease management. Similarly, biopharma companies are increasingly engaging companies such as ours to provide information on clinical trial participants’ DNA profiles in order to identify genomic variations that may be responsible for differing responses to pharmaceuticals, and particularly to oncology drugs, thereby increasing the efficiency of trials while lowering related costs. We believe tailored therapeutics can revolutionize oncology medicine through DNA-based testing services, enabling physicians and researchers to target the factors that make each patient and disease unique. We have created a unique position in the industry by providing targeted somatic analysis of tumor sample cells alongside germline analysis of an individuals' non-cancerous cells' DNA as we attempt to reach the next milestone in personalized medicine. Individuals are born with germline mutations and somatic mutations arise in tissues over the course of a lifetime.

We were incorporated in the State of Delaware on April 8, 1999 and have offices and state-of-the-art laboratories located in New Jersey, North Carolina, Shanghai (China), and Hyderabad, India. Our laboratories comply with the highest regulatory standards as appropriate for the services they deliver including CLIA, CAP, NY State and NABL (India). We have two advisory boards to counsel our scientific and clinical direction. Our Scientific Advisory Board is comprised of preeminent scientists and physicians from the fields of cancer biology, cancer pathology, cancer medicine and molecular genetics.Our Clinical Advisory Board is comprised of clinicians and scientists focused on clinical implementation of our proprietary tests and services and mapping those tests and services to patient needs.  Our services are built on a foundation of world-class scientific knowledge and intellectual property in solid and blood-borne cancers, as well as strong academic relationships with major cancer centers such as Memorial Sloan-Kettering, Mayo Clinic, and the National Cancer Institute.

Acquisition of Gentris Corporation

On July 16, 2014, we purchased substantially all of the assets of Gentris Corporation ("Gentris"), a laboratory specializing in pharmacogenomics profiling for therapeutic development, companion diagnostics and clinical trials. Gentris’ laboratory is located in Morrisville, North Carolina and the company has a CLIA and FDA-compliant laboratory facility in Shanghai, China. Upon closing of the acquisition transaction, Gentris Corporation was re-named Gentris, LLC and is now a wholly-owned subsidiary of Cancer Genetics, Inc. The acquisition allows us to expand our biopharma services.

The assets and liabilities of Gentris were recorded in our consolidated financial statements at their estimated fair values as of the acquisition date. The excess value of the consideration paid over the fair value of assets acquired and liabilities assumed was recorded as goodwill. Goodwill arising from the acquisition consists largely from a trained workforce in place and expected synergies with existing operations. Goodwill recorded in conjunction with the acquisition is deductible for income tax purposes. The total consideration for the Gentris acquisition is as follows:

	Amount
Cash paid at closing	$	3,250,000
Issuance of 147,843 common shares	1,271,745
Estimated fair value of contingent consideration	293,400
Total Purchase Price	$	4,815,145

The estimated fair value of contingent consideration is a potential earn-out which is payable in cash or shares of our common stock at our option, and is based upon a formula that provides for additional amounts, for revenues starting at $4.75 million, up to revenues of $8.55 million, plus a potential payment to be made in connection with the termination of a biorepository relationship with Gentris, based upon exit fees to be received by Gentris. The amounts used in computing the purchase price differ from the amounts in the purchase agreements due to fair value measurement conventions prescribed in accounting standards.

82

We incurred a finder's fee of $147,500 related to the transaction.

The transaction is being accounted for using the acquisition method of accounting for business combinations in accordance with GAAP. Under this method, the total consideration transferred to consummate the acquisition is being allocated to the identifiable tangible and intangible assets acquired and liabilities assumed based on their respective fair values as of the closing date of the acquisition. The acquisition method of accounting requires extensive use of estimates and judgments to allocate the consideration transferred to the identifiable tangible and intangible assets acquired and liabilities assumed. Accordingly, the allocation of the consideration transferred in the consolidated financial statements is preliminary and will be adjusted upon completion of the final valuation of the assets acquired and liabilities assumed. The final valuation of fixed assets, intangibles and deferred revenue is expected to be completed as soon as practicable but no later than twelve months after the closing date of the acquisition.

The preliminary allocation of the total purchase price to the fair value of the assets acquired and liabilities assumed as of July 16, 2014 are as follows:

	Amount
Accounts receivable	$	1,869,097
Other current assets	265,612
Current liabilities	(785,246		)
Deferred revenue, long-term	(937,773		)
Fixed Assets	1,950,885
Goodwill	2,452,570
Total Purchase Price	$	4,815,145

Acquisition of BioServe Biotechnologies (India) Pvt. Ltd.

On August 18, 2014 we entered into two agreements by which we acquired BioServe Biotechnologies (India) Pvt. Ltd., a premier genomics services provider serving both the research and clinical markets in India. This transaction was completed through a newly formed subsidiary, Cancer Genetics (India) Pvt. Ltd.

BioServe is a leading genomic service and next-generation sequencing company serving both the research and clinical markets based in Hyderabad, India. With the BioServe acquisition we believe we will be able to access the Indian healthcare market. The acquisition provides us with an infrastructure in India for developing lower cost manufacturing of probes and kits including probes and kits used for our proprietary FHACT test and access to one of the fastest-growing molecular and clinical diagnostic markets in the world. BioServe will continue to serve biotechnology and biopharmaceutical companies, diagnostic companies and research hospitals, including those owned or operated by the Indian government, as well as seek to expand its customer base.

The parties to the first agreement (the “India Agreement”) are the Company, Ramakishna V. Modali (the current general manager of BioServe, “Modali”), VenturEast Trustee Company Pvt Ltd and affiliates, its principal shareholder (“VenturEast”), and certain other shareholders residing in India all of whom in the aggregate owned approximately 74% of BioServe. The parties to the second share purchase agreement (the “US Agreement”) are the Company and BioServe Biotechnologies LTD, a Maryland corporation and an affiliate of BioServe which owned approximately 15% of BioServe, with the other outstanding shares held by the BioServe Employee Stock Ownership Plan which will remain in place.

The assets and liabilities of BioServe were recorded in the Company's consolidated financial statements at their estimated fair values as of the acquisition date. The excess value of the consideration paid over the fair value of assets acquired and liabilities assumed is recorded as goodwill. Goodwill arising from the acquisition consists largely from a trained workforce in place and expected synergies from new lines of business. Goodwill recorded in conjunction with the acquisition is not deductible for income tax purposes. The aggregate purchase price is as follows:

83

	Amount
Cash paid at closing	$	72,907
Notes payable due 12-18 months after closing	23,708
Notes payable (value of 84,278 common shares)	733,387
Issuance of 31,370 common shares	244,247
Total Purchase Price	$	1,074,249

The ultimate payment to VenturEast will be a cash payment equal to the value of 84,278 shares of our common stock at the time of payment. This payment will be made the earlier of 30 months from the date of the acquisition agreement (November 2016) or the date of a public offering by us of our common stock. This liability is subject to future adjustment based upon changes to our stock price. During the year ended December 31, 2014, we recognized a gain of $198,000 due to the decrease in value of this note. The amounts used in computing the purchase price differ from the amounts in the purchase agreements due to fair value measurement conventions prescribed in accounting standards.

The transaction is being accounted for using the acquisition method of accounting for business combinations in accordance with GAAP. Under this method, the total consideration transferred to consummate the acquisition is being allocated to the identifiable tangible and intangible assets acquired and liabilities assumed based on their respective fair values as of the closing date of the acquisition. The acquisition method of accounting requires extensive use of estimates and judgments to allocate the consideration transferred to the identifiable tangible and intangible assets acquired and liabilities assumed. Accordingly, the allocation of the consideration transferred in the consolidated financial statements is preliminary and will be adjusted upon completion of the final valuation of the assets acquired and liabilities assumed. The final valuation of fixed assets and intangibles is expected to be completed as soon as practicable but no later than twelve months after the closing date of the acquisition.

The preliminary allocation of the total purchase price to the fair value of the assets acquired and liabilities assumed as of August 18, 2014 are as follows:

	Amount
Accounts receivable	$	151,002
Other current assets	120,528
Fixed Assets	624,948
Other assets	416,869
Goodwill	541,565
Current liabilities	(758,614		)
Other liabilities	(22,049		)
Total Purchase Price	$	1,074,249

The following table provides certain proforma financial information for the Company as if the acquisitions discussed above occurred on January 1, 2012:

	Unaudited
	Year Ended December 31,
	2014			2013			2012
Revenue	$	14,365,402		$	15,767,519		$	12,528,553
Net loss	(18,498,333		)	(13,677,432		)	(7,918,262		)
Basic net loss per share	$	(1.94	)	$	(2.82	)	$	(5.20	)
Dilutive net loss per share	(1.98		)	(3.77		)	(10.13		)

The results of operations for the twelve months endedDecember 31, 2014 include the operations of Gentris from July 16, 2014 and BioServe from August 18, 2014 and include combined revenues of $3,296,465 and a combined net loss of $1,438,118.

84

Reverse Stock Splits

On February 8, 2013, we filed a charter amendment with the Secretary of State for the State of Delaware and effected a 1-for-2 reverse stock split of our common stock. On March 1, 2013, we filed another charter amendment with the Secretary of State for the State of Delaware and effected a 1-for-2.5 reverse stock split of our common stock. All shares and per share information referenced throughout the consolidated financial statements have been retroactively adjusted to reflect both reverse stock splits.

Public Offerings

On April 10, 2013, we sold 690,000 shares of common stock at a public offering price of $10.00 per share and completed our initial public offering (“IPO”) with gross proceeds of $6.9 million (net proceeds of $5 million). Upon the closing of the IPO, all shares of our then-outstanding Series A and Series B convertible preferred stock automatically converted into an aggregate of 1,287,325 shares of common stock. Concurrent with the IPO, certain derivative warrants with a fair value of $7.2 million were reclassified into equity due to the lapsing of anti-dilution provisions in the warrants. Also concurrent with the IPO, $9.6 million of debt converted into 963,430 shares of common stock. All references to our Series A convertible preferred stock refer collectively to the Series A and Series A-1 convertible preferred shares.

On August 19, 2013, we sold 1,500,000 shares of common stock at a public offering price of $10.00 per share resulting in gross proceeds of $15.0 million (net proceeds of $13.3 million). We used $3.5 million of the proceeds to repay certain indebtedness which was due on August 15, 2013 (see Note 6 for further discussion of the Company’s debt). On September 5, 2013, we sold 105,000 additional common shares pursuant to partial exercise of the underwriter’s over-allotment option which resulted in gross proceeds of $1.1 million (net proceeds of $947,000). All references to the sales of common stock mentioned in this paragraph are referred to as the “Secondary Offering.”

On October 28, 2013, we sold 3,286,700 shares of common stock, (including the underwriter’s overallotment of 428,700 shares), at a public offering price of $14.00 per share resulting in gross proceeds of $46.0 million (net proceeds of $42.3 million). All references to the sales of common stock mentioned in this paragraph are referred to as the “Follow-On Offering.”

Note 2. Significant Accounting Policies

Basis of presentation: We prepare our financial statements on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America.

Segment Reporting: Operating segments are defined as components of an enterprise about which separate discrete information is used by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. We view our operations and manage our business in one operating segment, which is the business of developing and selling diagnostic tests.

Liquidity: Our primary sources of liquidity have been funds generated from our debt financings and equity financings. In addition, we have generated funds from the following sources: (i) cash collections from our customers; (ii) grants from the National Institutes of Health and (iii) the sale of State of New Jersey net operating loss carryforwards.

Principles of consolidation: The accompanying consolidated financial statements include the accounts of Cancer Genetics, Inc. and our wholly owned subsidiaries, Cancer Genetics Italia S.r.l (“CGI Italia”), Gentris LLC (from July 16, 2014) and CGI India (BioServe) (from August 18, 2014).

All significant intercompany account balances and transactions have been eliminated in consolidation.

Use of estimates and assumptions: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates made by management include, among others, realization of amounts billed, realization of long-lived assets, realization of intangible assets, accruals for litigation and registration payments, assumptions used to value stock options, warrants and goodwill and the valuation of assets acquired and liabilities assumed from acquisitions. Actual results could differ from those estimates.

Risks and uncertainties: We operate in an industry that is subject to intense competition, government regulation and rapid technological change. Our operations are subject to significant risk and uncertainties including financial, operational, technological, regulatory, foreign operations, and other risks, including the potential risk of business failure.

Cash and cash equivalents: Highly liquid investments with original maturities of three months or less when purchased are considered to be cash equivalents. Financial instruments which potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents. We maintain cash and cash equivalents with high-credit quality financial institutions. At times, such amounts may exceed insured limits. We have not experienced any losses in such accounts and believe we are not exposed to any significant credit risk on our cash and cash equivalents.

Restricted cash: Represents cash held at financial institutions which we may not withdraw and which collateralizes certain of our financial commitments. All of our restricted cash is invested in interest bearing certificates of deposit. Our restricted cash collateralizes a fully-utilized $6.0 million line of credit with Wells Fargo Bank and a $300,000 letter of credit in favor of our landlord, pursuant to the terms of the lease for our Rutherford facility.

Revenue recognition: Revenue is recognized in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 605, Revenue Recognition, and ASC 954-605 Health Care Entities, Revenue Recognition which requires that four basic criteria must be met before revenue can be recognized: (1) persuasive evidence that an arrangement exists; (2) delivery has occurred and title and the risks and rewards of ownership have been transferred to the customer or services have been rendered; (3)the price is fixed or determinable; and (4) collectability is reasonably assured. In determining whether the price is fixed or determinable, we consider payment limits imposed by insurance carriers and Medicare and the amount of revenue recorded takes into account the historical percentage of revenue we have collected for each type of test for each payor category. Periodically, an adjustment is made to revenue to record differences between our anticipated cash receipts from insurance carriers and Medicare and actual receipts from such payors. For the periods presented, such adjustments were not significant. For some Clinical Service and Biopharma customers billed directly, revenue is recorded based upon the contractually agreed upon fee schedule. When assessing collectability, we consider whether we have sufficient payment history to reliably estimate a payor’s individual payment patterns. For new tests where there is no evidence of payment history at the time the tests are completed, we only recognize revenues once reimbursement experience can be established. We then recognize revenue equal to the amount of cash received. We do not bill customers for shipping and handling fees and do not collect any sales or other taxes.

Revenues from grants to support product development are recognized when costs and expenses under the terms of the grant have been incurred and payments under the grants become contractually due.

Accounts receivable: Accounts receivable are carried at original invoice amount less an estimate for contractual adjustments and doubtful receivables, the amounts of which are determined by an analysis of individual accounts. Our policy for assessing the collectability of receivables is dependent upon the major payor source of the underlying revenue. For direct bill clients, an assessment of credit worthiness is performed prior to initial engagement and is reassessed periodically. If deemed necessary, an allowance is established on receivables from direct bill clients. For insurance carriers where there is not an established pattern of collection, revenue is not recorded until cash is received. For receivables where insurance carriers have made payments to patients instead of directing payments to the Company, an allowance is established for a portion of such receivables. After reasonable collection efforts are exhausted, amounts deemed to be uncollectible are written off against the allowance for doubtful accounts. Since the Company only recognizes revenue to the extent it expects to collect such amounts, bad debt expense related to receivables from patient service revenue is recorded in general and administrative expense in the consolidated statement of operations. Recoveries of accounts receivable previously written off are recorded when received.

Deferred revenue: Payments received in advance of services rendered are recorded as deferred revenue and are subsequently recognized as revenue in the period in which the services are performed.

Fixed assets: Fixed assets consist of diagnostic equipment, furniture and fixtures and leasehold improvements. Fixed assets are carried at cost and are depreciated using the straight-line method over the estimated useful lives of the assets, which generally range from five to seven years. Leasehold improvements are depreciated over the lesser of the lease term or the estimated useful lives of the improvements using the straight-line method. Repairs and maintenance are charged to expense as incurred while improvements are capitalized. Upon sale, retirement or disposal of fixed assets, the accounts are relieved of the cost and the related accumulated depreciation with any gain or loss recorded to the consolidated statement of operations.

Fixed assets are reviewed for impairment whenever changes in circumstances indicate that the carrying amount of an asset may not be recoverable. These computations utilize judgments and assumptions inherent in our estimate of future cash flows to determine recoverability of these assets. If our assumptions about these assets were to change as a result of events or circumstances, we may be required to record an impairment loss.

Goodwill: Goodwill resulted from the purchases of Gentris and BioServe in 2014 as described in Note 1. In accordance with ASC 350, Intangibles - Goodwill and Other, we are required to test goodwill for impairment and adjust for impairment losses, if any, at least annually and on an interim basis if an event or circumstance indicates that it is likely impairment has occurred. Our annual goodwill impairment testing date is October 1 of each year. No such losses were incurred during the year ended December 31, 2014.

Goodwill
Balance, December 31, 2013	$	—
Purchased through acquisitions	2,994,135
Balance, December 31, 2014	$	2,994,135

Loan guarantee and financing fees: Loan guarantee fees are amortized on a straight-line basis over the term of the guarantee. Financing fees are amortized using the effective interest method over the term of the related debt.

Warrant liability: We have issued certain warrants which contain an exercise price adjustment feature in the event we issue additional equity instruments at a price lower than the exercise price of the warrant. The warrants are described herein as derivative warrants. We account for these derivative warrants as liabilities. These common stock purchase warrants do not trade in an active securities market, and as such, we estimate the fair value of these warrants using the binomial lattice valuation pricing model with the assumptions as follows: The risk-free interest rate for periods within the contractual life of the warrant is based on the U.S. Treasury yield curve. The expected life of the warrants is based upon the contractual life of the warrants. Volatility is estimated based on an average of the historical volatilities of the common stock of four entities with characteristics similar to those of the Company. Prior to our IPO, the measurement date fair value of the underlying common shares was based upon an external valuation of our shares. (See Notes 12 and 13). Subsequent to the IPO and Secondary Offering, we used the closing price of our shares on the OTC Bulletin Board and the NASDAQ Capital Market, respectively.

We compute the fair value of the warrant liability at each reporting period and the change in the fair value is recorded as non-cash expense or non-cash income. The key component in the value of the warrant liability is our stock price, which is subject to

87

significant fluctuation and is not under our control. The resulting effect on our net income (loss) is therefore subject to significant fluctuation and will continue to be so until the warrants are exercised, amended or expire. Assuming all other fair value inputs remain constant, we will record non-cash expense when the stock price increases and non-cash income when the stock price decreases.

Income taxes: Income taxes are provided for the tax effects of transactions reported in the consolidated financial statements and consist of taxes currently due plus deferred income taxes. Deferred income taxes are recognized for temporary differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future. Deferred income taxes are also recognized for net operating loss carryforwards that are available to offset future taxable income and research and development credits.

Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We have established a full valuation allowance on our deferred tax assets as of December 31, 2014 and 2013, therefore we have not recognized any tax benefit or expense in the periods presented.

ASC 740, Income Taxes, clarifies the accounting for uncertainty in income taxes recognized in the financial statements. ASC 740 provides that a tax benefit from uncertain tax positions may be recognized when it is more-likely-than-not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits of the position. Income tax positions must meet a more-likely-than-not recognition threshold to be recognized. ASC 740 also provides guidance on measurement, de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. At December 31, 2014 and 2013 we had no uncertain tax positions.

Our policy is to recognize interest and/or penalties related to income tax matters in income tax expense. There is no accrual for interest or penalties on our consolidated balance sheets at December 31, 2014 or 2013, and we have not recognized interest and/or penalties in the consolidated statements of operations for the years ended December 31, 2014, 2013 or 2012.

Patents: We account for intangible assets under ASC 350-30. Patents consist of legal fees incurred and are recorded at cost and amortized over the useful lives of the assets, using the straight-line method. Certain patents are in the legal application process and therefore are not currently being amortized. We review the carrying value of patents at the end of each reporting period. Based upon our review, there were no intangible asset impairments in 2014, 2013 or 2012. Accumulated amortization of patents as of December 31, 2014 and 2013 was approximately $84,000 and $56,000, respectively. Future amortization expense for legally approved patents (excluding patent applications in progress), is estimated at $34,900 per year through 2018, approximately $31,600 for 2019 and $93,400 thereafter.

Research and development: Research and development costs associated with service and product development include direct costs of payroll, employee benefits, stock-based compensation and supplies and an allocation of indirect costs including rent, utilities, depreciation and repairs and maintenance. All research and development costs are expensed as they are incurred.

Registration payment arrangements: We account for our obligations under registration payment arrangements in accordance with ASC 825-20, Registration Payment Arrangements. ASC 825-20 requires us to record a liability if we determine a registration payment is probable and if it can reasonably be estimated. As of both December 31, 2014 and 2013, we have an accrued liability of $300,000.

Stock-based compensation: Stock-based compensation is accounted for in accordance with the provisions of ASC 718, Compensation-Stock Compensation, which requires the measurement and recognition of compensation expense for all stock-based awards made to employees and directors based on estimated fair values on the grant date. We estimate the fair value of stock-based awards on the date of grant using the Black-Scholes option pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods using the straight-line method. See additional information in Note 11.

All issuances of stock options or other issuances of equity instruments to employees as the consideration for services received by us are accounted for based on the fair value of the equity instrument issued.

We account for stock-based compensation awards to non-employees in accordance with ASC 505-50, Equity Based Payments to Non-Employees. Under ASC 505-50, we determine the fair value of the warrants or stock-based compensation awards granted as either the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more reliably measurable. Stock-based compensation awards issued to non-employees are recorded in expense and additional paid-in capital in stockholders’ equity (deficit) over the applicable service periods based on the fair value of the awards or consideration received at the vesting date.

88

Fair value of financial instruments: The carrying amount of cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued expenses, approximate their estimated fair values due to the short term maturities of those financial instruments. These financial instruments are considered Level 1 measurements under the fair value hierarchy. The fair values of our notes payable, lines of credit and capital leases approximate carrying value under Level 2 of the fair value hierarchy. The fair value of warrants recorded as derivative liabilities, contingent consideration and note payable to VenturEast are described in Note 14.

Joint venture accounted for under the equity method: The Company records its joint venture investment following the equity method of accounting, reflecting its initial investment in the joint venture and its share of the joint venture’s net earnings or losses and distributions. The Company’s share of the joint venture’s net loss was approximately $940,000 in 2014 and $12,000 in 2013 (the first year of the joint venture’s operations) and is included in Research and development expense on the Consolidated Statement of Operations. The Company has a net receivable due from the joint venture of approximately $10,000 and $24,000 in 2014 and 2013, respectively, which is included in other assets in the Consolidated Balance Sheet. See additional information in Note 16.

Subsequent events: We have evaluated potential subsequent events through the date the financial statements were issued.

Recent Accounting Pronouncements: In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The updated standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either a full retrospective or retrospective with cumulative effect transition method. Early adoption is not permitted. The updated standard becomes effective for the Company in the first quarter of fiscal year 2017.  The Company has not yet selected a transition method and is currently evaluating the effect that the updated standard will have on the consolidated financial statements.

Earnings (loss) per share: Basic earnings (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares assumed to be outstanding during the period of computation. Diluted earnings per share is computed similar to basic earnings per share except that the numerator is adjusted for the change in fair value of the warrant liability (only if dilutive) and the denominator is increased to include the number of dilutive potential common shares outstanding during the period using the treasury stock method.

Basic net loss and diluted net loss per share data were computed as follows:

	2014			2013			2012
Numerator:
Net (loss) for basic earnings per share	$	(16,642,919	)	$	(12,372,553	)	$	(6,665,627	)

Revenue for Biopharma Services are customized solutions for patient stratification and treatment selection through an extensive suite of DNA-based testing services. Clinical Services are tests performed to provide information on diagnosis, prognosis and theranosis of cancers to guide patient management. These tests can be billed to Medicare, another third party insurer or the referring community hospital or other healthcare facility. Discovery Services are services that provide the tools and testing methods for companies and researchers seeking to identify new DNA-based biomarkers for disease. Grants includes revenue from grants. The breakdown of our Clinical Services revenue (as a percent of total revenue) is as follows:

	2014		2013		2012
Medicare	11	%	13	%	18	%
Other insurers	16	%	25	%	32	%
Other healthcare facilities	16	%	18	%	24	%
Total Clinical Services	43	%	55	%	74	%

We have historically derived a significant portion of our revenue from a limited number of test ordering sites. The test ordering sites are largely hospitals, cancer centers, reference laboratories, physician offices and clinical trial clients. Oncologists and pathologists at these sites order the tests on behalf of the needs of their oncology patients or as part of a clinical trial sponsored by a biopharmaceutical company in which the patient is being enrolled. We generally do not have formal, long-term written agreements with such test ordering sites, and, as a result, we may lose a significant test ordering site at any time.

The top five test ordering clients during 2014, 2013 and 2012 accounted for 56%, 69% and 58% respectively, of our testing volumes, with 38%, 36% and 46% respectively, of the test volume coming from community hospitals. During the year ended

91

December 31, 2014, two Biopharma clients accounted for approximately 23% and 12% respectively of our revenue. During the year ended December 31, 2013 there was one Biopharma client that accounted for approximately 40% of our revenue. During 2012 there were three clients, that each accounted for more than 10% of our revenue: a Biopharma client accounted for approximately 13%, a university teaching center accounted for approximately 11% and a community hospital accounted for approximately 10% of our revenue.

Note 4. Other Current Assets

At December 31, 2014 and 2013, other current assets consisted of the following:

	2014		2013
Inventory	$	279,894	$	198,789
Prepaid expenses	911,320		593,950
Grants receivable	—		71,877
	$	1,191,214	$	864,616

Note 5. Lease Commitments

We lease our laboratory, research facility and administrative office space under various operating leases. We have approximately 17,900 square feet of office and laboratory space in Rutherford, New Jersey, 24,900 square feet in Morrisville, North Carolina, 10,000 square feet in Hyderabad, India and 2,700 square feet in Shanghai, China. We have escalating lease agreements for both our New Jersey and North Carolina spaces which expire February 2018 and May 2020, respectively. These leases require monthly rent with periodic rent increases that vary from $1 to $2 per square foot of the rented premises per year. The difference between minimum rent and straight-line rent is recorded as deferred rent payable. The terms of our New Jersey lease require that a $300,000 security deposit for the facility be held in a stand by letter of credit in favor of the landlord (see Note 7).

We acquired office and scientific equipment under long term leases which have been capitalized at the present value of the minimum lease payments. The equipment under these capital leases had a cost of $395,687 and accumulated depreciation of $29,936, as of December 31, 2014.

Minimum future lease payments under all capital and operating leases as of December 31, 2014 are as follows:

	Capital Leases		Operating Leases		Total
December 31,
2015	$	74,280	$	854,195	$	928,475
2016	74,280		862,957		937,237
2017	61,625		870,407		932,032
2018	59,094		360,140		419,234
2019	59,094		320,885		379,979
Thereafter	83,800		135,075		218,875
Total minimum lease payments	$	412,173	$	3,403,659	$	3,815,832
Less amount representing interest	52,838
Present value of net minimum obligations	359,335
Less current obligation under capital lease	58,950
Long-term obligation under capital lease	$	300,385

Rent expense for the years ended December 31, 2014, 2013 and 2012 was $692,324, $550,882, and $516,173, respectively.

Note 6. Notes Payable and Lines of Credit

Below is a summary of our short-term and long-term debt obligations as of December 31, 2014 and 2013:

Lines of Credit, Long-Term	$	6,000,000	$	—

Business Line of Credit — Wells Fargo

At December 31, 2014 and 2013, we have fully utilized a line of credit with Wells Fargo Bank which provides for maximum borrowings of $6 million. On April 1, 2014 we entered into a credit agreement and re-negotiated the terms of our fully utilized line of credit with Wells Fargo Bank. The line of credit was extended through April 1, 2016 at a rate of interest equal to the Daily One Month LIBOR rate plus 1.75% (1.91% at December 31, 2014). The facility requires monthly interest payments.

The line of credit is collateralized with $6 million in cash. Additionally, we are required to maintain limits on capital spending and are restricted as to the amount we may pledge as collateral for additional borrowings from any source. The line of credit requires the repayment of principal, and any unpaid interest, in a single payment due upon maturity.

Conversion of Debt concurrent with IPO

On April 10, 2013, we completed our IPO and converted the following indebtedness into shares of common stock at the IPO price of $10.00 per share:

	Converted Amount		Common Shares
December 2011 Financing Transaction	$	4,500,000	450,000
2012 Convertible Debt Financing Transaction	3,000,000		300,000
December 2012 Bridge Financing Transaction	1,000,000		100,000
Business Lines of Credit (DAM)	1,000,000		100,000
Other Note Payable and accrued interest	134,300		13,430
	$	9,634,300	963,430

In connection with the conversion of debt into common stock, we expensed the applicable remaining debt discounts of $3.5 million, financing fees of $419,000 and a contingently recognizable beneficial conversion feature in the converted debt of $3 million.

December 2011 Financing Transaction

The December 2011 Credit Agreement was with John Pappajohn and Andrew Pecora (indirectly through an investment company), both then members of our board of directors, and NNJCA Capital, LLC (“NNJCA”), a limited liability company of which Dr. Pecora is a member. Mr. Pappajohn originally provided $4.0 million of financing, NNJCA originally provided $1.5 million of financing and Dr. Pecora provided $500,000 of financing under the Credit Agreement. On April 10, 2013, Mr. Pappajohn converted $4.0 million and Dr. Pecora converted $500,000 into 450,000 shares of our common stock at the IPO price of $10.00 per share concurrent with our IPO. The remaining outstanding balance of $1.5 million was repaid on August 19, 2013 using a portion of the proceeds from our Secondary Offering.

2012 Convertible Debt Financing Transaction

On April 10, 2013, the entire $3 million outstanding under a Restated Credit Agreement dated as of August 27, 2012, as amended and restated as of October 17, 2012, ($1,750,000 provided by Mr. Pappajohn and $1,250,000 provided by Mr. Mark Oman) was converted into 300,000 shares of common stock at the IPO price of $10 per share.

93

December 2012 Bridge Financing Transaction

On April 10, 2013, the entire $1 million outstanding under a credit agreement dated as of December 7, 2012, (all of which was provided by Mr. Pappajohn), was converted into 100,000 shares of common stock at the IPO price of $10.00 per share.

Business Line of Credit – DAM

On April 10, 2013, $1 million of indebtedness under this line was converted into 100,000 shares of common stock at the IPO price of $10 per share. The remaining outstanding balance of $2.0 million was repaid on August 19, 2013 using a portion of the proceeds from our Secondary Offering.

Other Note Payable

On April 10, 2013, a $100,000 note payable and accrued interest payable to Dr. Chaganti was converted into 13,430 shares of common stock at the IPO price of $10.00 per share.

Loss on Debt and Warrant Restructuring

We entered into a Restated Credit Agreement with Mr. Pappajohn and Mr. Oman in October 2012 to provide for additional borrowing of $1,000,000, which agreement also removed the conversion price adjustment of a 20% discount to the IPO or merger price if the IPO or merger price is less than $53.12 per share. We evaluated the application of ASC 470-50, Modifications and Extinguishments and ASC 470-60, Troubled Debt Restructurings by Debtors and concluded that the revised terms constituted a debt extinguishment, rather than a debt modification or troubled debt restructuring.

We cancelled certain warrants with an exercise price adjustment of a 20% discount to the IPO or merger price if the IPO or merger price is less than $53.13 per share and issued warrants without an exercise price adjustment to a 20% discount to the IPO or merger price if the IPO or merger price is less than $53.13 per share as compensation. In connection with these transactions, we recognized a loss on debt and warrant restructuring during 2012 as presented below:

Restated 2012 convertible debt financing transaction	$	1,506,512
Amend warrants granted for guarantee of business line of credit	268,000
Amend warrants granted for 2011 convertible debt financing transaction	545,000
Settle warrants granted for guarantee of business line of credit	(129,500		)
Settle warrants granted for 2011 convertible debt financing transaction	(328,000		)
Loss on debt and warrant restructuring - 2012	$	1,862,012

Note 7. Letter of Credit

We maintain a $300,000 letter of credit in favor of our landlord pursuant to the terms of the lease for our Rutherford facility. At December 31, 2014 the letter of credit was fully secured by the restricted cash disclosed on our Consolidated Balance Sheet.

Note 8. Fixed Assets

Fixed assets are summarized by major classifications as follows:

Note 9. Income Taxes

The provision for income taxes for the years ended December 31, 2014, 2013 and 2012 differs from the approximate amount of income tax benefit determined by applying the U.S. federal income tax rate to pre-tax loss, due to the following:

During January and December 2014, we sold $28,640,223 of gross State of New Jersey NOL carryforwards relating to tax years 2009 through 2012, resulting in the receipt of $2,350,185. During 2013, we sold $8,018,107 of gross State of New Jersey NOL carryforwards, resulting in the receipt of $663,900.

We transferred the NOL carryforwards through the Technology Business Tax Certificate Transfer Program sponsored by the New Jersey Economic Development Authority.

Due to a history of losses we have generated since inception, we believe it is more-likely-than-not that all of the deferred tax assets will not be realized as of December 31, 2014 and 2013. Therefore, we have recorded a full valuation allowance on our deferred tax assets. We have net operating loss carryforwards for federal income tax purposes of approximately $57,000,000 as of December 31, 2014. The net operating loss carryforwards will begin to expire in 2027. Utilization of these carryforwards is subject to limitation due to ownership changes that may delay the utilization of a portion of the carryforwards.

Note 10. Capital Stock

IPO

On April 10, 2013, we completed our IPO in which we issued and sold 690,000 shares of common stock (including the underwriter’s overallotment of 90,000 shares) at a public offering price of $10.00 per share resulting in gross proceeds of $6.9 million. In connection with the offering, all outstanding shares of Series A preferred stock were converted into 376,525 shares of common stock, and all outstanding shares of Series B preferred stock were converted into 910,800 shares of common stock. Concurrent with the IPO, we issued 2,000 shares of common stock to Cleveland Clinic pursuant to our license agreement with Cleveland Clinic.

Secondary Offering

On August 19, 2013, we sold 1,500,000 shares of common stock at a public offering price of $10.00 per share resulting in gross proceeds of $15.0 million ($13.3 million of net proceeds after offering expenses and underwriting discounts).

On September 5, 2013, we sold 105,000 additional common shares pursuant to the underwriter’s partial exercise of the over-allotment option which resulted in gross proceeds of $1.1 million ($947,000 of net proceeds after offering expenses and underwriting discounts).

Follow-On Offering

On October 28, 2013, we sold 3,286,700 shares of common stock, (including the underwriter’s overallotment of 428,700 shares), at a public offering price of $14.00 per share resulting in gross proceeds of $46.0 million (net proceeds of $42.3 million).

Preferred Stock

We are currently authorized to issue up to 9,764,000 shares of preferred stock.

Note 11. Stock Option Plans

We have two equity incentive plans: the 2008 Stock Option Plan (the “2008 Plan”) and the 2011 Equity Incentive Plan (the “2011 Plan”, and together with the 2008 Plan, the “Stock Option Plans”). The Stock Option Plans are meant to provide additional incentive to officers, employees and consultants to remain in our employment. Options granted are generally exercisable for up to 10 years.

The Board of Directors adopted the 2011 Plan on June 30, 2011 and reserved 350,000 shares of common stock for issuance under the 2011 Plan. On May 22, 2014, the stockholders voted to increase the number of shares reserved by the plan to 2,000,000 shares of common stock under several types of equity awards including stock options, stock appreciation rights, restricted stock awards and other awards defined in the 2011 Plan.

The Board of Directors adopted the 2008 Plan on April 29, 2008 and reserved 251,475 shares of common stock for issuance under the plan. On April 1, 2010, the stockholders voted to increase the number of shares reserved by the plan to 550,000. We are authorized to issue incentive stock options or non-statutory stock options to eligible participants.

We have also issued 48,000 options outside of the Stock Option Plans.

At December 31, 2014, 386,044 shares remain available for future awards under the 2011 Plan and 89,051 shares remain available for future awards under the 2008 Plan.

As of December 31, 2014, no stock appreciation rights and 227,500 shares of restricted stock had been awarded under the Stock Option Plans.

Prior to our IPO in April 2013, the Board of Directors authorized an offer to certain employee and non-employee options holders on the following terms: those holding stock options with a strike price of $25.00 or more had the opportunity to exchange their options for 60% of the number of options currently held with an exercise price equal to the IPO price, which was $10.00 per share, and those holding stock options with a strike price of $12.50 had the opportunity to exchange their options for 80% of the number of options currently held with an exercise price equal to the IPO price which was $10.00 per share. On April 5, 2013, our initial public offering became effective and 336,300 options with exercise prices ranging from $12.50 to $33.80 were exchanged for 242,070 options with an exercise price of $10.00. The options did not result in the recognition of incremental compensation cost. In addition, 53,500 options which were approved to be issued and priced at the IPO price were issued to employees with an exercise price of $10.00 per share.

A summary of employee and non-employee stock option activity for the years ended December 31, 2014, 2013 and 2012 is as follows:

	Options Outstanding				Weighted- Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value
	Number of Shares		Weighted- Average Exercise Price

Exercisable, December 31, 2014	635,435		$	9.14	6.72	$	478,219

Aggregate intrinsic value represents the difference between the fair value of our common stock and the exercise price of outstanding, in-the-money options. The fair value of our common stock was $6.68 and $13.78 as of December 31, 2014 and 2013, respectively, and the estimated fair value of our common stock was $9.60 as of December 31, 2012. During the year ended December 31, 2014 and 2013, we received $79,018 and $1,640, respectively from the exercise of options. Also during the year ended December 31, 2014, an option holder exercised options to purchase 12,000 shares of common stock with an exercise price of $10.00 per share using the net issue exercise method whereby the option holder surrendered 11,429 shares in payment in full of the exercise price resulting in net issuance of 571 shares of common stock. The options exercised in 2014 and 2013 had a total intrinsic value of $120,510 and $1,630, respectively. Options were not exercised in 2012.

As of December 31, 2014, total unrecognized compensation cost related to non-vested stock options granted to employees was $6,058,774, which we expect to recognize over the next 3.70 years.

As of December 31, 2014 and 2013, total unrecognized compensation cost related to non-vested stock options granted to non-employees was $645,739 and $94,359, respectively, which we expect to recognize over the next 2.95 and 1.78 years, respectively. The estimate of unrecognized non-employee compensation is based on the fair value of the non-vested options as of December 31, 2014 and 2013.

The following table summarizes information about outstanding and vested stock options granted to employees and non-employees as of December 31, 2014 as follows:

The fair value of options granted to employees is estimated on the grant date using the Black-Scholes option valuation model. This valuation model for stock-based compensation expense requires us to make assumptions and judgments about the variables used in the calculation, including the fair value of our common stock (see Note 13), the expected term (the period of time that the options granted are expected to be outstanding), the volatility of our common stock, a risk-free interest rate, and expected dividends. We also estimate forfeitures of unvested stock options. To the extent actual forfeitures differ from the estimates, the difference will be recorded as a cumulative adjustment in the period estimates are revised. No compensation cost is recorded for options that do not vest. We use the simplified calculation of expected life described in the SEC’s Staff Accounting Bulletin No. 107, Share-Based Payment, and volatility is based on an average of the historical volatilities of the common stock of three entities with characteristics similar to those of the Company. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option. We use an expected dividend yield of zero, as we do not anticipate paying any dividends in the foreseeable future. Expected forfeitures are assumed to be zero due to the plan design which has monthly vesting after an initial cliff vesting period.

The following table presents the weighted-average assumptions used to estimate the fair value of options granted to employees during the periods presented:

In 2010, we issued an aggregate of 80,000 options to non-employees with an exercise price of $25.00. As described above, on April 5, 2013, these options were exchanged for 48,000 options with an exercise price of $10.00. In October 2013, we issued 10,000 options to a non-employee with an exercise price of $15.39. In May 2014, we issued 200,000 options to a Director, with an exercise price of $15.89. See Note 17 for additional information. The following table presents the weighted-average assumptions used to estimate the fair value of options reaching their measurement date for non-employees during the periods presented:

Starting in 2013, restricted stock awards have been granted to employees, directors and consultants as compensation for services. At December 31, 2014, there was $852,206 of unrecognized compensation cost related to non-vested restricted stock granted to employees; we expect to recognize the cost over 3 years. At December 31, 2014, there was $12,948 of unrecognized compensation cost related to non-vested restricted stock granted to non-employees, which we expect to recognize over 0.78 years.

The following table summarizes the activities for our non-vested restricted stock awards for the years ended December 31, 2014 and 2013:

	Non-vested Restricted Stock Awards

Note 12. Warrants

We have issued certain warrants which contain an exercise price adjustment feature in the event we issue additional equity instruments at a price lower than the exercise price of the warrant. The warrants are described herein as derivative warrants. For all derivative warrants, in the event equity instruments are issued at a price lower than the exercise price of the warrant, the exercise price is adjusted to the price of the new equity instruments issued (price adjustment feature). For certain of these warrants, the number of shares underlying the warrant is also adjusted to an amount computed by dividing the proceeds of the warrant under its original terms by the revised exercise price (share adjustment feature). These warrants are initially recorded as a warrant liability at fair value with a corresponding entry to the loan guarantee fee asset, debt discount, additional paid-in capital or expense dependent upon the service provided in exchange for the warrant grant. Subsequently, any change in fair value is recognized in earnings until such time as the warrants are exercised, amended or expire. As of December 31, 2014 all warrants with a share adjustment feature have either expired or have been exercised.

In connection with debt guarantees and extensions, we issued 1,051,506 warrants to Mr. Pappajohn, a member of our Board of Directors and stockholder, at various dates (see Note 17). These warrants were initially recorded at fair value as a loan guarantee fee amortized over the period of the guarantee to interest expense. The aggregate issue date fair value of the debt guarantee warrants was $1,555,000 in 2012, and $831,000 in 2011. There were no debt guarantee warrants issued in 2014 or 2013.

In connection with the acquisition of a line of credit, we issued 60,000 warrants to DAM in March 2011 with an initial estimated fair value of $1,019,000. In March 2012 in exchange for an extension of that line, we issued 15,000 warrants with an initial estimated fair value of $306,000. See Note 6.

We issued 200 warrants to a consultant for services provided in February and March 2011 and 4,000 warrants to a member of our Board of Directors in connection with the March 2011 line of credit agreement with DAM. These warrants were recorded as consulting expense at an initial estimated fair value of $69,000 and expire in March 2016.

In connection with the December 2011 Financing Transaction we granted a total of 112,940 warrants at various dates to Mr. Pappajohn, Dr. Pecora and NNJCA. The aggregate issue date fair value of these financing fee warrants was $1,522,000 in 2012 and $951,000 in 2011. In October 2012, 37,646 of these warrants were surrendered in exchange for an increase to the prepayment penalty, and 75,294 were amended in exchange for 20,669 additional warrants with an initial estimated fair value of $606,000. Also in October 2012, Mr. Pappajohn agreed to extend a portion of the debt’s maturity date and in exchange we issued 9,412 additional warrants with an initial estimated fair value of $267,000. See Note 6.

In connection with the 2012 Convertible Debt Financing Transaction, we granted a total of 28,235 warrants to Mr. Pappajohn and Mr. Oman with an initial estimated fair value of $1,107,000. In October 2012, these warrants were surrendered in exchange for additional financing and 114,510 new warrants with an initial estimated fair value of $4,090,000. See Note 6.

On September 6, 2012, we extended the maturity date of warrants to purchase 70,598 shares of our common stock which were due to expire on September 10, 2012 to September 28, 2012. On September 27, 2012, we extended the maturity date of 65,328 of these warrants to September 10, 2013. In exchange, the warrants became subject to a lock-up agreement for 180 days after the consummation of an IPO on the same terms as other lock-up agreements in favor of the underwriters of an offering. We determined the fair value of the warrant extensions to be approximately $144,000, which was recorded as general and administrative expense.

On October 22, 2012, in exchange for amending warrants issued in connection with his guarantee of the Wells Fargo debt, we issued warrants to purchase 10,157 shares of our common stock to Mr. Pappajohn with an exercise price equal to the lesser of (i) $42.50 per share and (ii) the IPO or merger price per share. These warrants were recorded as a financing fee expense at an estimated fair value of $298,000.

In connection with the December 2012 Bridge Financing transaction, we granted 23,529 warrants to Mr. Pappajohn with an initial estimated fair value of $837,000. See Note 6.

100

During 2012, warrants to purchase 54,910 shares were exercised and $690,227 was received and recorded as increases to common stock and additional paid-in capital. An additional 15,164 warrants expired unexercised. In connection with the 2012 Convertible Debt Financing Transaction, we granted 4,118 warrants to Mr. Pappajohn and 2,941 warrants to Mr. Oman on February 22, 2013. The warrants have a ten-year term and an exercise price equal to the IPO price of $10.00 per share. Pursuant to a subsequent agreement, the warrants held by Mr. Pappajohn have an exercise price of $15.00 per share. These warrants were initially recorded at fair value as a financing fee asset and were amortized over the period of the note to interest expense. The issue date fair value of these warrants was $221,000.

In connection with the December 2012 Bridge Financing Transaction, we granted 2,353ten-year warrants with an exercise price equal to the IPO price of $10.00 per share to Mr. Pappajohn on March 7, 2013. Mr. Pappajohn subsequently agreed that if our final IPO price was below $15.00, there would be no further adjustment to the price or number of shares covered by the warrants held by him. These warrants were initially recorded at fair value as a financing fee asset and were amortized over the period of the note to interest expense. The issue date fair value of these warrants was $47,000.

On February 11, 2013, John Pappajohn agreed to limit certain anti-dilution rights in his warrants to purchase shares of the Company’s common stock. Subject to the consummation of an IPO prior to April 13, 2013, Mr. Pappajohn agreed that if the final IPO price was below $15.00, the exercise price of the warrants held by him would adjust to $15.00 and the number of shares underlying the warrants would be adjusted as if the IPO price were $15.00 and then there would be no further adjustment to the price or number of shares covered by warrants held by him. In February 2013, certain warrant holders agreed to waive the price and share adjustment provisions of their warrants, except for the anti-dilution provisions related to stock splits, subdivisions and combinations, with respect to an aggregate of 114,030 shares of common stock underlying such warrants, effective immediately following the consummation of our IPO on April 10, 2013 at $10.00 per share.

On April 10, 2013, the Company completed the IPO at $10.00 per share. The shares of common stock issuable upon the exercise of warrants increased by 838,889 shares and the exercise prices of 1,656,860 warrants were adjusted as a result of share and exercise price adjustment features in certain warrants.

On April 29, 2013, the Company received $96,000 from shareholders who exercised warrants to purchase 24,000 shares of common stock at $4.00 per share.

On July 6, 2013, a warrant holder exercised a warrant to purchase 6,000 shares of common stock at an exercise price of $4.00 per share using the net issuance exercise method whereby 2,072 shares were surrendered as payment in full of the exercise price resulting in a net issuance of 3,928 shares.

On July 8, 2013, the Company received $96,000 from shareholders who exercised warrants to purchase 24,000 shares of common stock at $4.00 per share.

Note 13. Fair Value of Warrants

The following tables summarize the assumptions used in computing the fair value of derivative warrants subject to fair value accounting at the date of issue during the years ended December 31, 2014, 2013 and 2012 and at December 31, 2014, December 31, 2013 and April 5, 2013 (IPO valuation date). In computing the fair value of the warrants, if the stated exercise price of the warrants exceeded the assumed value of the Company stock at the date the fair value was being computed, the exercise price and number of shares (if applicable) underlying the warrants were adjusted to reflect an assumed trigger of the price and/or share adjustment features related to the applicable warrants. Such adjustments were only applicable to 2012 and 2013 due to the relative price of the warrants and the assumed Company stock price:

The assumed ranges of Company stock prices used in computing the warrant fair value for warrants issued during the year is as follows: in 2014, $6.68—$19.86; in 2013, $9.60—$20.26; in 2012, $9.60—$33.80. In determining the fair value of warrants issued at each reporting date, the assumed Company stock price was $6.68 and $13.78 (the closing price on the NASDAQ Capital Market) at December 31, 2014 and 2013.

The following table summarizes the derivative warrant activity subject to fair value accounting for the years ended December 31, 2014, 2013 and 2012:

Note 14. Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The Fair Value Measurements and Disclosures Topic of the FASB Accounting Standards Codification requires the use of valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect our own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In that regard, the Topic establishes a fair value hierarchy for valuation inputs that give the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs.

The fair value hierarchy is as follows:

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that we have the ability to access as of the measurement date.

Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

105

Level 3: Significant unobservable inputs that reflect our own assumptions about the assumptions that market participants would use in pricing an asset or liability.

The following table summarizes the financial liabilities measured at fair value on a recurring basis segregated by the level of valuation inputs within the fair value hierarchy utilized to measure fair value:

	2014
	Total		Quoted Prices in Active Markets for Identical Assets (Level 1)	Significant Other Observable Inputs (Level 2)	Significant Unobservable Inputs (Level 3)
Warrant liability	$	52,000	—	—	$	52,000
Gentris contingent consideration	293,400		—	—	293,400
Notes payable to VenturEast	534,828		—	—	534,828
	$	880,228	—	—	$	880,228
	2013
	Total		Quoted Prices in Active Markets for Identical Assets (Level 1)	Significant Other Observable Inputs (Level 2)	Significant Unobservable Inputs (Level 3)
Warrant liability	$	594,000	—	—	$	594,000

The warrant liability consists of stock warrants we issued that contain an exercise price adjustment feature. In accordance with derivative accounting for warrants, we calculated the fair value of warrants and the assumptions used are described in Note 13, “Fair Value of Warrants”. Realized and unrealized gains and losses related to the change in fair value of the warrant liability are included in other income (expense) on the Consolidated Statement of Operations.

The value of the Gentris contingent consideration was determined using a discounted cash flow of the expected payments required by the purchase agreement.

The ultimate payment to VenturEast will be the value of 84,278 shares of common stock at the time of payment. The value of the note payable to VenturEast was determined using the fair value of our common stock less a discount for credit risk. During the year ended December 31, 2014 we recognized a gain of $198,000 due to the decrease in value of the note. Realized and unrealized gains and losses related to the change in fair value of the note are included in other income (expense) on the Consolidated Statement of Operations.

A table summarizing the activity for the derivative warrant liability which is measured at fair value using Level 3 inputs is presented in Note 13. The following table summarizes the activity of the notes payable to VenturEast and Gentris contingent consideration which were measured at fair value using Level 3 inputs:

	Note Payable			Gentris Contingent
	to VenturEast			Consideration
Fair value at January 1, 2014	$	—		$	—
Fair value at issuance	733,387			293,400
Change in fair value	(198,559		)	—
Fair value at December 31, 2014	$	534,828		$	293,400

Note 15. Contingencies

In the normal course of business, the Company is involved in various claims and legal proceedings. In the opinion of management, the ultimate liability or disposition thereof is not expected to have a material adverse effect on our financial condition, results of operations or liquidity.

Note 16. Joint Venture Agreement

In November 2011, we entered into an affiliation agreement with the Mayo Foundation for Medical Education and Research (“Mayo”), subsequently amended. Under the agreement, we formed a joint venture with Mayo in May 2013 to focus on developing oncology diagnostic services and tests utilizing next generation sequencing. The joint venture is a limited liability company, with each party initially holding fifty percent of the issued and outstanding membership interests of the new entity (the “JV”). In exchange for our membership interest in the JV, we made an initial capital contribution of $1.0 million in October 2013. In addition, we issued 10,000 shares of our common stock to Mayo pursuant to our affiliation agreement and recorded an expense of approximately $175,000. We also recorded additional expense of approximately $231,000 during the fourth quarter of 2013 related to shares issued to Mayo in November of 2011 as the JV achieved certain performance milestones. In the third quarter of 2014 we made an additional $1.0 million capital contribution.

The agreement also requires aggregate total capital contributions by us of up to an additional $4.0 million. We currently anticipate that we will make capital contributions of $1.0 million in the second quarter of 2015. The timing of the remaining installments is subject to the JV's achievement of certain operational milestones agreed upon by the board of governors of the JV. In exchange for its membership interest, Mayo’s capital contribution will take the form of cash, staff, services, hardware and software resources, laboratory space and instrumentation, the fair market value of which will be approximately equal to $6.0 million. Mayo’s continued contribution will also be conditioned upon the JV’s achievement of certain milestones.

The joint venture is considered a variable interest entity under ASC 810-10, but we are not the primary beneficiary as we do not have the power to direct the activities of the joint venture that most significantly impact its performance. Our evaluation of ability to impact performance is based on our equal board membership and voting rights and day to day management functions which are performed by the Mayo personnel.

Note 17. Related Party Transactions

John Pappajohn, a member of the Board of Directors and stockholder, had personally guaranteed our revolving line of credit with Wells Fargo Bank through March 31, 2014. As consideration for his guarantee, as well as each of the eight extensions of this facility through March 31, 2014, Mr. Pappajohn received warrants to purchase an aggregate of 1,051,506 shares of common stock of which Mr. Pappajohn assigned warrants to purchase 284,000 shares of common stock to certain third parties. Through December 31, 2014, warrants to purchase 440,113 shares of common stock have been exercised by Mr. Pappajohn and 233,333 warrants to purchase common stock have expired. After adjustment pursuant to the terms of the warrants in conjunction with our IPO, the number of these warrants outstanding retained by Mr. Pappajohn was 352,312 at $15.00 per share on December 31, 2014.

In addition, John Pappajohn also had loaned us an aggregate of $6,750,000 (all of which was converted into 675,000 shares of common stock at the IPO price of $10.00 per share). In connection with these loans, Mr. Pappajohn received warrants to purchase an aggregate of 202,630 shares of common stock. After adjustment pursuant to the terms of the warrants in conjunction with our IPO, the number of warrants outstanding was 436,079 at $15.00 per share at December 31, 2014.

Effective January 6, 2014, the board of directors appointed John Pappajohn to serve as the Chairman of the Board, a position previously held by Dr. Raju S.K. Chaganti. As compensation for serving as the Chairman of the Board, the Company will pay Mr. Pappajohn $100,000 per year and granted to Mr. Pappajohn 25,000 restricted shares of the Company's common stock, and options to purchase an aggregate of 100,000 shares of the Company's common stock. The options have a term of ten years from the date on which they were granted. The restricted stock and the options each vest in two equal installments on the one year anniversary and the two year anniversary of the date on which Mr. Pappajohn became the Chairman of the Board.

In August 2010, we entered into a consulting agreement with Equity Dynamics, Inc. (“EDI”), an entity controlled by John Pappajohn, pursuant to which EDI received a monthly fee of $10,000. The consulting agreement was terminated effective March 31, 2014. Subsequently the Company entered into a new consulting agreement with EDI effective April 1, 2014 pursuant to which it will receive a monthly fee of $10,000. We expensed $120,000 annually for the years ended December 31, 2014, 2013 and 2012 related to this agreement.

On May 19, 2006, we issued a convertible promissory note in favor of our then Chairman and founder, Dr. Chaganti, the holder, which obligated us to pay the holder the sum of $100,000, together with interest at the rate of 8.5% per annum, due April 1, 2014. Interest expense was $2,400 and $8,400 for the years ended December 31, 2013 and 2012, respectively. On April 10, 2013 the note and accrued interest converted into 13,430 shares of common stock at the IPO price of $10.00 per share. Pursuant to a consulting and advisory agreement, Dr. Chaganti also received options to purchase a total of 36,000 shares of common stock at a price of $10.00 per share which vested over a two year period. Total non-cash stock-based compensation recognized under the consulting agreement for the years ended December 31, 2014, 2013 and 2012 was $0, $76,220 and $430,600, respectively. Additionally, on September 15, 2010, we entered into a three year consulting agreement with Dr. Chaganti which was subsequently renewed through December 31, 2016 pursuant to which Dr. Chaganti receives $5,000 per month for providing consulting and technical support services. Total expenses for each of the years ended December 31, 2014, 2013 and 2012 were $60,000. Pursuant

107

to the terms of the renewed consulting agreement, Dr. Chaganti received an option to purchase 200,000 shares of our common stock at a purchase price of $15.89 per share vesting over a period of four years. Total non-cash stock-based compensation recognized under this consulting agreement for the years ended December 31, 2014, 2013 and 2012 were $341,000, $0 and $0. Also pursuant to the consulting agreement, Dr. Chaganti assigned to us all rights to any inventions which he may invent during the course of rendering consulting services to us. In exchange for this assignment, if the USPTO issues a patent for an invention on which Dr. Chaganti is listed as an inventor, we are required to pay Dr. Chaganti (i) a one-time payment of $50,000 and (ii)1% of any net revenues we receive from any licensed sales of the invention. In 2014 we paid Dr. Chaganti $150,000 which was recognized as an expense in fiscal 2013 when three patents were issued. Also in February 2015, we paid Dr. Chaganti $150,000 for which was recognized as an expense in 2014 when three additional patents were issued.

Andrew Pecora (indirectly through an investment company), when a member of our board of directors, and NNJCA, a limited liability company of which Dr. Pecora is a member originally provided $0.5 and $1.5 million of financing, respectively, under a Credit Agreement dated as of December 21, 2011, as amended and restated as of February 13, 2012. On April 10, 2013, NNJCA converted $0.5 million of its outstanding indebtedness into 50,000 shares of our common stock at the IPO price of $10.00 per share concurrent with our IPO. On August 19, 2013, the remaining principal under these notes were repaid to Dr. Pecora and NNJCA using a portion of the proceeds from our Secondary Offering. The loan bore an annual interest rate equal to the prime rate plus 6.25% (9.50% at August 19, 2013). We paid a pre-payment penalty due to Pecora and NNJCA of $130,000 of which $32,667 was paid upon conversion of the notes and the remaining balance paid on August 19, 2013.

On August 15, 2010, we entered into a two-year consulting agreement with Dr. Pecora, then a member of our board of directors, pursuant to which Dr. Pecora received $5,000 per month for providing consulting and advisory services. The cash component of this agreement was terminated by mutual consent in August 2011. Dr. Pecora also received stock options under the consulting and advisory agreement to purchase a total of 12,000 shares of common stock at price of $25.00 per share which vested over a two year period. Total expenses for 2014, 2013 and 2012 under the consulting agreement were $0 , $0, $142,740, respectively, expensed under the stock option plan.

In February 2012, we granted 28,235 warrants proportionately to Pecora and NNJCA upon their funding of $0.5 million and $1.5 million, respectively, under a new Credit Agreement. (See Notes 6 and 12). On May 15, 2012 and on August 14, 2012, we issued 4,706 of these warrants proportionately to Pecora and NNJCA (Notes 6 and 12). On October 15, 2012, Dr. Pecora and NNJCA agreed to surrender warrants to purchase an aggregate of 37,646 shares of our common stock issued in connection with this transaction in exchange for an amendment to increase the pre-payment penalties by $130,000.

None.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures.

We evaluated, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities and Exchange Act of 1934 (“Exchange Act”), as amended) as of December 31, 2014, the end of the period covered by this report on Form 10-K. Based on this evaluation, our President and Chief Executive Officer (principal executive officer) and our Chief Financial Officer (principal accounting and financial officer) have concluded that our disclosure controls and procedures were effective at December 31, 2014. Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act (i) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and were operating in an effective manner for the period covered by this report, and (ii) is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.

Management’s Report on Internal Control Over Financial Reporting.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934.

The Company’s internal control over financial reporting is a process designed 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:

• Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

• Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of our management and directors; and

• Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s 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. Also, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions or because of declines in the degree of compliance with policies or procedures.

We completed an acquisition of Gentris Corporation on July 16, 2014 and of BioServe Biotechnologies (India) Pvt. Ltd on August 18, 2014. Management's assessment of and conclusion on the effectiveness of our internal control over financial reporting excludes the internal controls over the financial reporting of these entities. These acquisitions contributed approximately 32 percent of our net sales for the year ended December 31, 2014 and accounted for approximately 15 percent of our total assets as of December 31, 2014. Registrants are permitted to exclude acquisitions from their assessment of internal controls over financial reporting during the first year if, among other circumstances and factors, there is not adequate time between the consummation date of the acquisition and the assessment date for assessing internal controls.

Our management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2014. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control-Integrated Framework (1992).

Based on management’s assessment, as of December 31, 2014, the Company’s internal control over financial reporting was effective.

Revenue for Biopharma Services are customized solutions for patient stratification and treatment selection through an extensive suite of DNA-based testing services. Clinical Services are tests performed to provide information on diagnosis, prognosis and theranosis of cancers to guide patient management. These tests can be billed to Medicare, another third party insurer or the referring community hospital or other healthcare facility. Discovery Services are services that provide the tools and testing methods for companies and researchers seeking to identify new DNA-based biomarkers for disease. Grants includes revenue from grants. The breakdown of our Clinical Services revenue (as a percent of total revenue) is as follows:

	2014		2013		2012
Medicare	11	%	13	%	18	%
Other insurers	16	%	25	%	32	%
Other healthcare facilities	16	%	18	%	24	%
Total Clinical Services	43	%	55	%	74	%

We have historically derived a significant portion of our revenue from a limited number of test ordering sites. The test ordering sites are largely hospitals, cancer centers, reference laboratories, physician offices and clinical trial clients. Oncologists and pathologists at these sites order the tests on behalf of the needs of their oncology patients or as part of a clinical trial sponsored by a biopharmaceutical company in which the patient is being enrolled. We generally do not have formal, long-term written agreements with such test ordering sites, and, as a result, we may lose a significant test ordering site at any time.

The top five test ordering clients during 2014, 2013 and 2012 accounted for 56%, 69% and 58% respectively, of our testing volumes, with 38%, 36% and 46% respectively, of the test volume coming from community hospitals. During the year ended December 31, 2014, two Biopharma clients accounted for approximately 23% and 12% respectively of our revenue. During the year ended December 31, 2013 there was one Biopharma client that accounted for approximately 40% of our revenue. During 2012 there were three clients, that each accounted for more than 10% of our revenue: a Biopharma client accounted for approximately 13%, a university teaching center accounted for approximately 11% and a community hospital accounted for approximately 10% of our revenue.

Accounting Policies [Abstract]

Significant Accounting Policies

Significant Accounting Policies

Basis of presentation: We prepare our financial statements on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America.

Segment Reporting: Operating segments are defined as components of an enterprise about which separate discrete information is used by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. We view our operations and manage our business in one operating segment, which is the business of developing and selling diagnostic tests.

Liquidity: Our primary sources of liquidity have been funds generated from our debt financings and equity financings. In addition, we have generated funds from the following sources: (i) cash collections from our customers; (ii) grants from the National Institutes of Health and (iii) the sale of State of New Jersey net operating loss carryforwards.

Principles of consolidation: The accompanying consolidated financial statements include the accounts of Cancer Genetics, Inc. and our wholly owned subsidiaries, Cancer Genetics Italia S.r.l (“CGI Italia”), Gentris LLC (from July 16, 2014) and CGI India (BioServe) (from August 18, 2014).

All significant intercompany account balances and transactions have been eliminated in consolidation.

Use of estimates and assumptions: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates made by management include, among others, realization of amounts billed, realization of long-lived assets, realization of intangible assets, accruals for litigation and registration payments, assumptions used to value stock options, warrants and goodwill and the valuation of assets acquired and liabilities assumed from acquisitions. Actual results could differ from those estimates.

Risks and uncertainties: We operate in an industry that is subject to intense competition, government regulation and rapid technological change. Our operations are subject to significant risk and uncertainties including financial, operational, technological, regulatory, foreign operations, and other risks, including the potential risk of business failure.

Cash and cash equivalents: Highly liquid investments with original maturities of three months or less when purchased are considered to be cash equivalents. Financial instruments which potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents. We maintain cash and cash equivalents with high-credit quality financial institutions. At times, such amounts may exceed insured limits. We have not experienced any losses in such accounts and believe we are not exposed to any significant credit risk on our cash and cash equivalents.

Restricted cash: Represents cash held at financial institutions which we may not withdraw and which collateralizes certain of our financial commitments. All of our restricted cash is invested in interest bearing certificates of deposit. Our restricted cash collateralizes a fully-utilized $6.0 million line of credit with Wells Fargo Bank and a $300,000 letter of credit in favor of our landlord, pursuant to the terms of the lease for our Rutherford facility.

Revenue recognition: Revenue is recognized in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 605, Revenue Recognition, and ASC 954-605 Health Care Entities, Revenue Recognition which requires that four basic criteria must be met before revenue can be recognized: (1) persuasive evidence that an arrangement exists; (2) delivery has occurred and title and the risks and rewards of ownership have been transferred to the customer or services have been rendered; (3)the price is fixed or determinable; and (4) collectability is reasonably assured. In determining whether the price is fixed or determinable, we consider payment limits imposed by insurance carriers and Medicare and the amount of revenue recorded takes into account the historical percentage of revenue we have collected for each type of test for each payor category. Periodically, an adjustment is made to revenue to record differences between our anticipated cash receipts from insurance carriers and Medicare and actual receipts from such payors. For the periods presented, such adjustments were not significant. For some Clinical Service and Biopharma customers billed directly, revenue is recorded based upon the contractually agreed upon fee schedule. When assessing collectability, we consider whether we have sufficient payment history to reliably estimate a payor’s individual payment patterns. For new tests where there is no evidence of payment history at the time the tests are completed, we only recognize revenues once reimbursement experience can be established. We then recognize revenue equal to the amount of cash received. We do not bill customers for shipping and handling fees and do not collect any sales or other taxes.

Revenues from grants to support product development are recognized when costs and expenses under the terms of the grant have been incurred and payments under the grants become contractually due.

Accounts receivable: Accounts receivable are carried at original invoice amount less an estimate for contractual adjustments and doubtful receivables, the amounts of which are determined by an analysis of individual accounts. Our policy for assessing the collectability of receivables is dependent upon the major payor source of the underlying revenue. For direct bill clients, an assessment of credit worthiness is performed prior to initial engagement and is reassessed periodically. If deemed necessary, an allowance is established on receivables from direct bill clients. For insurance carriers where there is not an established pattern of collection, revenue is not recorded until cash is received. For receivables where insurance carriers have made payments to patients instead of directing payments to the Company, an allowance is established for a portion of such receivables. After reasonable collection efforts are exhausted, amounts deemed to be uncollectible are written off against the allowance for doubtful accounts. Since the Company only recognizes revenue to the extent it expects to collect such amounts, bad debt expense related to receivables from patient service revenue is recorded in general and administrative expense in the consolidated statement of operations. Recoveries of accounts receivable previously written off are recorded when received.

Deferred revenue: Payments received in advance of services rendered are recorded as deferred revenue and are subsequently recognized as revenue in the period in which the services are performed.

Fixed assets: Fixed assets consist of diagnostic equipment, furniture and fixtures and leasehold improvements. Fixed assets are carried at cost and are depreciated using the straight-line method over the estimated useful lives of the assets, which generally range from five to seven years. Leasehold improvements are depreciated over the lesser of the lease term or the estimated useful lives of the improvements using the straight-line method. Repairs and maintenance are charged to expense as incurred while improvements are capitalized. Upon sale, retirement or disposal of fixed assets, the accounts are relieved of the cost and the related accumulated depreciation with any gain or loss recorded to the consolidated statement of operations.

Fixed assets are reviewed for impairment whenever changes in circumstances indicate that the carrying amount of an asset may not be recoverable. These computations utilize judgments and assumptions inherent in our estimate of future cash flows to determine recoverability of these assets. If our assumptions about these assets were to change as a result of events or circumstances, we may be required to record an impairment loss.

Goodwill: Goodwill resulted from the purchases of Gentris and BioServe in 2014 as described in Note 1. In accordance with ASC 350, Intangibles - Goodwill and Other, we are required to test goodwill for impairment and adjust for impairment losses, if any, at least annually and on an interim basis if an event or circumstance indicates that it is likely impairment has occurred. Our annual goodwill impairment testing date is October 1 of each year. No such losses were incurred during the year ended December 31, 2014.

Goodwill
Balance, December 31, 2013	$	—
Purchased through acquisitions	2,994,135
Balance, December 31, 2014	$	2,994,135

Loan guarantee and financing fees: Loan guarantee fees are amortized on a straight-line basis over the term of the guarantee. Financing fees are amortized using the effective interest method over the term of the related debt.

Warrant liability: We have issued certain warrants which contain an exercise price adjustment feature in the event we issue additional equity instruments at a price lower than the exercise price of the warrant. The warrants are described herein as derivative warrants. We account for these derivative warrants as liabilities. These common stock purchase warrants do not trade in an active securities market, and as such, we estimate the fair value of these warrants using the binomial lattice valuation pricing model with the assumptions as follows: The risk-free interest rate for periods within the contractual life of the warrant is based on the U.S. Treasury yield curve. The expected life of the warrants is based upon the contractual life of the warrants. Volatility is estimated based on an average of the historical volatilities of the common stock of four entities with characteristics similar to those of the Company. Prior to our IPO, the measurement date fair value of the underlying common shares was based upon an external valuation of our shares. (See Notes 12 and 13). Subsequent to the IPO and Secondary Offering, we used the closing price of our shares on the OTC Bulletin Board and the NASDAQ Capital Market, respectively.

We compute the fair value of the warrant liability at each reporting period and the change in the fair value is recorded as non-cash expense or non-cash income. The key component in the value of the warrant liability is our stock price, which is subject to significant fluctuation and is not under our control. The resulting effect on our net income (loss) is therefore subject to significant fluctuation and will continue to be so until the warrants are exercised, amended or expire. Assuming all other fair value inputs remain constant, we will record non-cash expense when the stock price increases and non-cash income when the stock price decreases.

Income taxes: Income taxes are provided for the tax effects of transactions reported in the consolidated financial statements and consist of taxes currently due plus deferred income taxes. Deferred income taxes are recognized for temporary differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future. Deferred income taxes are also recognized for net operating loss carryforwards that are available to offset future taxable income and research and development credits.

Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We have established a full valuation allowance on our deferred tax assets as of December 31, 2014 and 2013, therefore we have not recognized any tax benefit or expense in the periods presented.

ASC 740, Income Taxes, clarifies the accounting for uncertainty in income taxes recognized in the financial statements. ASC 740 provides that a tax benefit from uncertain tax positions may be recognized when it is more-likely-than-not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits of the position. Income tax positions must meet a more-likely-than-not recognition threshold to be recognized. ASC 740 also provides guidance on measurement, de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. At December 31, 2014 and 2013 we had no uncertain tax positions.

Our policy is to recognize interest and/or penalties related to income tax matters in income tax expense. There is no accrual for interest or penalties on our consolidated balance sheets at December 31, 2014 or 2013, and we have not recognized interest and/or penalties in the consolidated statements of operations for the years ended December 31, 2014, 2013 or 2012.

Patents: We account for intangible assets under ASC 350-30. Patents consist of legal fees incurred and are recorded at cost and amortized over the useful lives of the assets, using the straight-line method. Certain patents are in the legal application process and therefore are not currently being amortized. We review the carrying value of patents at the end of each reporting period. Based upon our review, there were no intangible asset impairments in 2014, 2013 or 2012. Accumulated amortization of patents as of December 31, 2014 and 2013 was approximately $84,000 and $56,000, respectively. Future amortization expense for legally approved patents (excluding patent applications in progress), is estimated at $34,900 per year through 2018, approximately $31,600 for 2019 and $93,400 thereafter.

Research and development: Research and development costs associated with service and product development include direct costs of payroll, employee benefits, stock-based compensation and supplies and an allocation of indirect costs including rent, utilities, depreciation and repairs and maintenance. All research and development costs are expensed as they are incurred.

Registration payment arrangements: We account for our obligations under registration payment arrangements in accordance with ASC 825-20, Registration Payment Arrangements. ASC 825-20 requires us to record a liability if we determine a registration payment is probable and if it can reasonably be estimated. As of both December 31, 2014 and 2013, we have an accrued liability of $300,000.

Stock-based compensation: Stock-based compensation is accounted for in accordance with the provisions of ASC 718, Compensation-Stock Compensation, which requires the measurement and recognition of compensation expense for all stock-based awards made to employees and directors based on estimated fair values on the grant date. We estimate the fair value of stock-based awards on the date of grant using the Black-Scholes option pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods using the straight-line method. See additional information in Note 11.

All issuances of stock options or other issuances of equity instruments to employees as the consideration for services received by us are accounted for based on the fair value of the equity instrument issued.

We account for stock-based compensation awards to non-employees in accordance with ASC 505-50, Equity Based Payments to Non-Employees. Under ASC 505-50, we determine the fair value of the warrants or stock-based compensation awards granted as either the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more reliably measurable. Stock-based compensation awards issued to non-employees are recorded in expense and additional paid-in capital in stockholders’ equity (deficit) over the applicable service periods based on the fair value of the awards or consideration received at the vesting date.

Fair value of financial instruments: The carrying amount of cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued expenses, approximate their estimated fair values due to the short term maturities of those financial instruments. These financial instruments are considered Level 1 measurements under the fair value hierarchy. The fair values of our notes payable, lines of credit and capital leases approximate carrying value under Level 2 of the fair value hierarchy. The fair value of warrants recorded as derivative liabilities, contingent consideration and note payable to VenturEast are described in Note 14.

Joint venture accounted for under the equity method: The Company records its joint venture investment following the equity method of accounting, reflecting its initial investment in the joint venture and its share of the joint venture’s net earnings or losses and distributions. The Company’s share of the joint venture’s net loss was approximately $940,000 in 2014 and $12,000 in 2013 (the first year of the joint venture’s operations) and is included in Research and development expense on the Consolidated Statement of Operations. The Company has a net receivable due from the joint venture of approximately $10,000 and $24,000 in 2014 and 2013, respectively, which is included in other assets in the Consolidated Balance Sheet. See additional information in Note 16.

Subsequent events: We have evaluated potential subsequent events through the date the financial statements were issued.

Recent Accounting Pronouncements: In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The updated standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either a full retrospective or retrospective with cumulative effect transition method. Early adoption is not permitted. The updated standard becomes effective for the Company in the first quarter of fiscal year 2017.  The Company has not yet selected a transition method and is currently evaluating the effect that the updated standard will have on the consolidated financial statements.

Earnings (loss) per share: Basic earnings (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares assumed to be outstanding during the period of computation. Diluted earnings per share is computed similar to basic earnings per share except that the numerator is adjusted for the change in fair value of the warrant liability (only if dilutive) and the denominator is increased to include the number of dilutive potential common shares outstanding during the period using the treasury stock method.

Basic net loss and diluted net loss per share data were computed as follows:

In computing the fair value of the warrants, if the stated exercise price of the warrants exceeded the assumed value of the Company stock at the date the fair value was being computed, the exercise price and number of shares (if applicable) underlying the warrants were adjusted to reflect an assumed trigger of the price and/or share adjustment features related to the applicable warrants. Such adjustments were only applicable to 2012 and 2013 due to the relative price of the warrants and the assumed Company stock price:

Joint Venture Agreement

Equity Method Investments and Joint Ventures [Abstract]

Joint Venture Agreement

Joint Venture Agreement

In November 2011, we entered into an affiliation agreement with the Mayo Foundation for Medical Education and Research (“Mayo”), subsequently amended. Under the agreement, we formed a joint venture with Mayo in May 2013 to focus on developing oncology diagnostic services and tests utilizing next generation sequencing. The joint venture is a limited liability company, with each party initially holding fifty percent of the issued and outstanding membership interests of the new entity (the “JV”). In exchange for our membership interest in the JV, we made an initial capital contribution of $1.0 million in October 2013. In addition, we issued 10,000 shares of our common stock to Mayo pursuant to our affiliation agreement and recorded an expense of approximately $175,000. We also recorded additional expense of approximately $231,000 during the fourth quarter of 2013 related to shares issued to Mayo in November of 2011 as the JV achieved certain performance milestones. In the third quarter of 2014 we made an additional $1.0 million capital contribution.

The agreement also requires aggregate total capital contributions by us of up to an additional $4.0 million. We currently anticipate that we will make capital contributions of $1.0 million in the second quarter of 2015. The timing of the remaining installments is subject to the JV's achievement of certain operational milestones agreed upon by the board of governors of the JV. In exchange for its membership interest, Mayo’s capital contribution will take the form of cash, staff, services, hardware and software resources, laboratory space and instrumentation, the fair market value of which will be approximately equal to $6.0 million. Mayo’s continued contribution will also be conditioned upon the JV’s achievement of certain milestones.

The joint venture is considered a variable interest entity under ASC 810-10, but we are not the primary beneficiary as we do not have the power to direct the activities of the joint venture that most significantly impact its performance. Our evaluation of ability to impact performance is based on our equal board membership and voting rights and day to day management functions which are performed by the Mayo personnel.

Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2014

Accounting Policies [Abstract]

Basis of presentation

Basis of presentation: We prepare our financial statements on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America.

Segment Reporting

Segment Reporting: Operating segments are defined as components of an enterprise about which separate discrete information is used by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. We view our operations and manage our business in one operating segment, which is the business of developing and selling diagnostic tests.

Liquidity

Liquidity: Our primary sources of liquidity have been funds generated from our debt financings and equity financings. In addition, we have generated funds from the following sources: (i) cash collections from our customers; (ii) grants from the National Institutes of Health and (iii) the sale of State of New Jersey net operating loss carryforwards.

Principles of consolidation

Principles of consolidation: The accompanying consolidated financial statements include the accounts of Cancer Genetics, Inc. and our wholly owned subsidiaries, Cancer Genetics Italia S.r.l (“CGI Italia”), Gentris LLC (from July 16, 2014) and CGI India (BioServe) (from August 18, 2014).

All significant intercompany account balances and transactions have been eliminated in consolidation.

Use of estimates and assumptions

Use of estimates and assumptions: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates made by management include, among others, realization of amounts billed, realization of long-lived assets, realization of intangible assets, accruals for litigation and registration payments, assumptions used to value stock options, warrants and goodwill and the valuation of assets acquired and liabilities assumed from acquisitions. Actual results could differ from those estimates.

Risks and uncertainties

Risks and uncertainties: We operate in an industry that is subject to intense competition, government regulation and rapid technological change. Our operations are subject to significant risk and uncertainties including financial, operational, technological, regulatory, foreign operations, and other risks, including the potential risk of business failure.

Cash and cash equivalents

Cash and cash equivalents: Highly liquid investments with original maturities of three months or less when purchased are considered to be cash equivalents. Financial instruments which potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents. We maintain cash and cash equivalents with high-credit quality financial institutions. At times, such amounts may exceed insured limits. We have not experienced any losses in such accounts and believe we are not exposed to any significant credit risk on our cash and cash equivalents.

Revenue recognition

Revenue recognition: Revenue is recognized in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 605, Revenue Recognition, and ASC 954-605 Health Care Entities, Revenue Recognition which requires that four basic criteria must be met before revenue can be recognized: (1) persuasive evidence that an arrangement exists; (2) delivery has occurred and title and the risks and rewards of ownership have been transferred to the customer or services have been rendered; (3)the price is fixed or determinable; and (4) collectability is reasonably assured. In determining whether the price is fixed or determinable, we consider payment limits imposed by insurance carriers and Medicare and the amount of revenue recorded takes into account the historical percentage of revenue we have collected for each type of test for each payor category. Periodically, an adjustment is made to revenue to record differences between our anticipated cash receipts from insurance carriers and Medicare and actual receipts from such payors. For the periods presented, such adjustments were not significant. For some Clinical Service and Biopharma customers billed directly, revenue is recorded based upon the contractually agreed upon fee schedule. When assessing collectability, we consider whether we have sufficient payment history to reliably estimate a payor’s individual payment patterns. For new tests where there is no evidence of payment history at the time the tests are completed, we only recognize revenues once reimbursement experience can be established. We then recognize revenue equal to the amount of cash received. We do not bill customers for shipping and handling fees and do not collect any sales or other taxes.

Revenues from grants to support product development are recognized when costs and expenses under the terms of the grant have been incurred and payments under the grants become contractually due.

Accounts receivable

Accounts receivable: Accounts receivable are carried at original invoice amount less an estimate for contractual adjustments and doubtful receivables, the amounts of which are determined by an analysis of individual accounts. Our policy for assessing the collectability of receivables is dependent upon the major payor source of the underlying revenue. For direct bill clients, an assessment of credit worthiness is performed prior to initial engagement and is reassessed periodically. If deemed necessary, an allowance is established on receivables from direct bill clients. For insurance carriers where there is not an established pattern of collection, revenue is not recorded until cash is received. For receivables where insurance carriers have made payments to patients instead of directing payments to the Company, an allowance is established for a portion of such receivables. After reasonable collection efforts are exhausted, amounts deemed to be uncollectible are written off against the allowance for doubtful accounts. Since the Company only recognizes revenue to the extent it expects to collect such amounts, bad debt expense related to receivables from patient service revenue is recorded in general and administrative expense in the consolidated statement of operations. Recoveries of accounts receivable previously written off are recorded when received.

Deferred revenue

Deferred revenue: Payments received in advance of services rendered are recorded as deferred revenue and are subsequently recognized as revenue in the period in which the services are performed.

Fixed assets

Fixed assets: Fixed assets consist of diagnostic equipment, furniture and fixtures and leasehold improvements. Fixed assets are carried at cost and are depreciated using the straight-line method over the estimated useful lives of the assets, which generally range from five to seven years. Leasehold improvements are depreciated over the lesser of the lease term or the estimated useful lives of the improvements using the straight-line method. Repairs and maintenance are charged to expense as incurred while improvements are capitalized. Upon sale, retirement or disposal of fixed assets, the accounts are relieved of the cost and the related accumulated depreciation with any gain or loss recorded to the consolidated statement of operations.

Fixed assets are reviewed for impairment whenever changes in circumstances indicate that the carrying amount of an asset may not be recoverable. These computations utilize judgments and assumptions inherent in our estimate of future cash flows to determine recoverability of these assets. If our assumptions about these assets were to change as a result of events or circumstances, we may be required to record an impairment loss.

Goodwill

Goodwill: Goodwill resulted from the purchases of Gentris and BioServe in 2014 as described in Note 1. In accordance with ASC 350, Intangibles - Goodwill and Other, we are required to test goodwill for impairment and adjust for impairment losses, if any, at least annually and on an interim basis if an event or circumstance indicates that it is likely impairment has occurred. Our annual goodwill impairment testing date is October 1 of each year.

Loan guarantee and financing fees

Loan guarantee and financing fees: Loan guarantee fees are amortized on a straight-line basis over the term of the guarantee. Financing fees are amortized using the effective interest method over the term of the related debt.

Warrant liability

Warrant liability: We have issued certain warrants which contain an exercise price adjustment feature in the event we issue additional equity instruments at a price lower than the exercise price of the warrant. The warrants are described herein as derivative warrants. We account for these derivative warrants as liabilities. These common stock purchase warrants do not trade in an active securities market, and as such, we estimate the fair value of these warrants using the binomial lattice valuation pricing model with the assumptions as follows: The risk-free interest rate for periods within the contractual life of the warrant is based on the U.S. Treasury yield curve. The expected life of the warrants is based upon the contractual life of the warrants. Volatility is estimated based on an average of the historical volatilities of the common stock of four entities with characteristics similar to those of the Company. Prior to our IPO, the measurement date fair value of the underlying common shares was based upon an external valuation of our shares. (See Notes 12 and 13). Subsequent to the IPO and Secondary Offering, we used the closing price of our shares on the OTC Bulletin Board and the NASDAQ Capital Market, respectively.

We compute the fair value of the warrant liability at each reporting period and the change in the fair value is recorded as non-cash expense or non-cash income. The key component in the value of the warrant liability is our stock price, which is subject to significant fluctuation and is not under our control. The resulting effect on our net income (loss) is therefore subject to significant fluctuation and will continue to be so until the warrants are exercised, amended or expire. Assuming all other fair value inputs remain constant, we will record non-cash expense when the stock price increases and non-cash income when the stock price decreases.

Income taxes

Income taxes: Income taxes are provided for the tax effects of transactions reported in the consolidated financial statements and consist of taxes currently due plus deferred income taxes. Deferred income taxes are recognized for temporary differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future. Deferred income taxes are also recognized for net operating loss carryforwards that are available to offset future taxable income and research and development credits.

Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We have established a full valuation allowance on our deferred tax assets as of December 31, 2014 and 2013, therefore we have not recognized any tax benefit or expense in the periods presented.

ASC 740, Income Taxes, clarifies the accounting for uncertainty in income taxes recognized in the financial statements. ASC 740 provides that a tax benefit from uncertain tax positions may be recognized when it is more-likely-than-not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits of the position. Income tax positions must meet a more-likely-than-not recognition threshold to be recognized. ASC 740 also provides guidance on measurement, de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. At December 31, 2014 and 2013 we had no uncertain tax positions.

Our policy is to recognize interest and/or penalties related to income tax matters in income tax expense.

Patents

Patents: We account for intangible assets under ASC 350-30. Patents consist of legal fees incurred and are recorded at cost and amortized over the useful lives of the assets, using the straight-line method. Certain patents are in the legal application process and therefore are not currently being amortized. We review the carrying value of patents at the end of each reporting period.

Research and development

Research and development: Research and development costs associated with service and product development include direct costs of payroll, employee benefits, stock-based compensation and supplies and an allocation of indirect costs including rent, utilities, depreciation and repairs and maintenance. All research and development costs are expensed as they are incurred.

Registration payment arrangements

Registration payment arrangements: We account for our obligations under registration payment arrangements in accordance with ASC 825-20, Registration Payment Arrangements. ASC 825-20 requires us to record a liability if we determine a registration payment is probable and if it can reasonably be estimated.

Stock-based compensation

Stock-based compensation: Stock-based compensation is accounted for in accordance with the provisions of ASC 718, Compensation-Stock Compensation, which requires the measurement and recognition of compensation expense for all stock-based awards made to employees and directors based on estimated fair values on the grant date. We estimate the fair value of stock-based awards on the date of grant using the Black-Scholes option pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods using the straight-line method. See additional information in Note 11.

All issuances of stock options or other issuances of equity instruments to employees as the consideration for services received by us are accounted for based on the fair value of the equity instrument issued.

We account for stock-based compensation awards to non-employees in accordance with ASC 505-50, Equity Based Payments to Non-Employees. Under ASC 505-50, we determine the fair value of the warrants or stock-based compensation awards granted as either the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more reliably measurable. Stock-based compensation awards issued to non-employees are recorded in expense and additional paid-in capital in stockholders’ equity (deficit) over the applicable service periods based on the fair value of the awards or consideration received at the vesting date.

Fair value of financial instruments

Fair value of financial instruments: The carrying amount of cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued expenses, approximate their estimated fair values due to the short term maturities of those financial instruments. These financial instruments are considered Level 1 measurements under the fair value hierarchy. The fair values of our notes payable, lines of credit and capital leases approximate carrying value under Level 2 of the fair value hierarchy.

Joint venture accounted for under the equity method

Joint venture accounted for under the equity method: The Company records its joint venture investment following the equity method of accounting, reflecting its initial investment in the joint venture and its share of the joint venture’s net earnings or losses and distributions.

Subsequent events

Subsequent events: We have evaluated potential subsequent events through the date the financial statements were issued.

New accounting pronouncement

Recent Accounting Pronouncements: In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The updated standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either a full retrospective or retrospective with cumulative effect transition method. Early adoption is not permitted. The updated standard becomes effective for the Company in the first quarter of fiscal year 2017.  The Company has not yet selected a transition method and is currently evaluating the effect that the updated standard will have on the consolidated financial statements.

Earnings (loss) per share

Earnings (loss) per share: Basic earnings (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares assumed to be outstanding during the period of computation. Diluted earnings per share is computed similar to basic earnings per share except that the numerator is adjusted for the change in fair value of the warrant liability (only if dilutive) and the denominator is increased to include the number of dilutive potential common shares outstanding during the period using the treasury stock method.

We are an oncology diagnostics company focused on developing, commercializing and providing DNA-based tests and services to improve the personalization of cancer treatment and to better inform biopharmaceutical companies of genomic factors influencing subject responses to therapeutics. Our vision is to become the oncology diagnostics partner for companies and clinicians by participating in the entire care continuum from bench to bedside. We believe the diagnostic industry is undergoing a metamorphosis in its approach to oncology testing, embracing individualized medicine as a means to drive higher standards of patient treatment and disease management. Similarly, biopharma companies are increasingly engaging companies such as ours to provide information on clinical trial participants’ DNA profiles in order to identify genomic variations that may be responsible for differing responses to pharmaceuticals, and particularly to oncology drugs, thereby increasing the efficiency of trials while lowering related costs. We believe tailored therapeutics can revolutionize oncology medicine through DNA-based testing services, enabling physicians and researchers to target the factors that make each patient and disease unique. We have created a unique position in the industry by providing targeted somatic analysis of tumor sample cells alongside germline analysis of an individuals' non-cancerous cells' DNA as we attempt to reach the next milestone in personalized medicine. Individuals are born with germline mutations and somatic mutations arise in tissues over the course of a lifetime.

We were incorporated in the State of Delaware on April 8, 1999 and have offices and state-of-the-art laboratories located in New Jersey, North Carolina, Shanghai (China), and Hyderabad, India. Our laboratories comply with the highest regulatory standards as appropriate for the services they deliver including CLIA, CAP, NY State and NABL (India). We have two advisory boards to counsel our scientific and clinical direction. Our Scientific Advisory Board is comprised of preeminent scientists and physicians from the fields of cancer biology, cancer pathology, cancer medicine and molecular genetics.Our Clinical Advisory Board is comprised of clinicians and scientists focused on clinical implementation of our proprietary tests and services and mapping those tests and services to patient needs.  Our services are built on a foundation of world-class scientific knowledge and intellectual property in solid and blood-borne cancers, as well as strong academic relationships with major cancer centers such as Memorial Sloan-Kettering, Mayo Clinic, and the National Cancer Institute.

Acquisition of Gentris Corporation

On July 16, 2014, we purchased substantially all of the assets of Gentris Corporation ("Gentris"), a laboratory specializing in pharmacogenomics profiling for therapeutic development, companion diagnostics and clinical trials. Gentris’ laboratory is located in Morrisville, North Carolina and the company has a CLIA and FDA-compliant laboratory facility in Shanghai, China. Upon closing of the acquisition transaction, Gentris Corporation was re-named Gentris, LLC and is now a wholly-owned subsidiary of Cancer Genetics, Inc. The acquisition allows us to expand our biopharma services.

The assets and liabilities of Gentris were recorded in our consolidated financial statements at their estimated fair values as of the acquisition date. The excess value of the consideration paid over the fair value of assets acquired and liabilities assumed was recorded as goodwill. Goodwill arising from the acquisition consists largely from a trained workforce in place and expected synergies with existing operations. Goodwill recorded in conjunction with the acquisition is deductible for income tax purposes. The total consideration for the Gentris acquisition is as follows:

	Amount
Cash paid at closing	$	3,250,000
Issuance of 147,843 common shares	1,271,745
Estimated fair value of contingent consideration	293,400
Total Purchase Price	$	4,815,145

The estimated fair value of contingent consideration is a potential earn-out which is payable in cash or shares of our common stock at our option, and is based upon a formula that provides for additional amounts, for revenues starting at $4.75 million, up to revenues of $8.55 million, plus a potential payment to be made in connection with the termination of a biorepository relationship with Gentris, based upon exit fees to be received by Gentris. The amounts used in computing the purchase price differ from the amounts in the purchase agreements due to fair value measurement conventions prescribed in accounting standards.

We incurred a finder's fee of $147,500 related to the transaction.

The transaction is being accounted for using the acquisition method of accounting for business combinations in accordance with GAAP. Under this method, the total consideration transferred to consummate the acquisition is being allocated to the identifiable tangible and intangible assets acquired and liabilities assumed based on their respective fair values as of the closing date of the acquisition. The acquisition method of accounting requires extensive use of estimates and judgments to allocate the consideration transferred to the identifiable tangible and intangible assets acquired and liabilities assumed. Accordingly, the allocation of the consideration transferred in the consolidated financial statements is preliminary and will be adjusted upon completion of the final valuation of the assets acquired and liabilities assumed. The final valuation of fixed assets, intangibles and deferred revenue is expected to be completed as soon as practicable but no later than twelve months after the closing date of the acquisition.

The preliminary allocation of the total purchase price to the fair value of the assets acquired and liabilities assumed as of July 16, 2014 are as follows:

	Amount
Accounts receivable	$	1,869,097
Other current assets	265,612
Current liabilities	(785,246		)
Deferred revenue, long-term	(937,773		)
Fixed Assets	1,950,885
Goodwill	2,452,570
Total Purchase Price	$	4,815,145

Acquisition of BioServe Biotechnologies (India) Pvt. Ltd.

On August 18, 2014 we entered into two agreements by which we acquired BioServe Biotechnologies (India) Pvt. Ltd., a premier genomics services provider serving both the research and clinical markets in India. This transaction was completed through a newly formed subsidiary, Cancer Genetics (India) Pvt. Ltd.

BioServe is a leading genomic service and next-generation sequencing company serving both the research and clinical markets based in Hyderabad, India. With the BioServe acquisition we believe we will be able to access the Indian healthcare market. The acquisition provides us with an infrastructure in India for developing lower cost manufacturing of probes and kits including probes and kits used for our proprietary FHACT test and access to one of the fastest-growing molecular and clinical diagnostic markets in the world. BioServe will continue to serve biotechnology and biopharmaceutical companies, diagnostic companies and research hospitals, including those owned or operated by the Indian government, as well as seek to expand its customer base.

The parties to the first agreement (the “India Agreement”) are the Company, Ramakishna V. Modali (the current general manager of BioServe, “Modali”), VenturEast Trustee Company Pvt Ltd and affiliates, its principal shareholder (“VenturEast”), and certain other shareholders residing in India all of whom in the aggregate owned approximately 74% of BioServe. The parties to the second share purchase agreement (the “US Agreement”) are the Company and BioServe Biotechnologies LTD, a Maryland corporation and an affiliate of BioServe which owned approximately 15% of BioServe, with the other outstanding shares held by the BioServe Employee Stock Ownership Plan which will remain in place.

The assets and liabilities of BioServe were recorded in the Company's consolidated financial statements at their estimated fair values as of the acquisition date. The excess value of the consideration paid over the fair value of assets acquired and liabilities assumed is recorded as goodwill. Goodwill arising from the acquisition consists largely from a trained workforce in place and expected synergies from new lines of business. Goodwill recorded in conjunction with the acquisition is not deductible for income tax purposes. The aggregate purchase price is as follows:

	Amount
Cash paid at closing	$	72,907
Notes payable due 12-18 months after closing	23,708
Notes payable (value of 84,278 common shares)	733,387
Issuance of 31,370 common shares	244,247
Total Purchase Price	$	1,074,249

The ultimate payment to VenturEast will be a cash payment equal to the value of 84,278 shares of our common stock at the time of payment. This payment will be made the earlier of 30 months from the date of the acquisition agreement (November 2016) or the date of a public offering by us of our common stock. This liability is subject to future adjustment based upon changes to our stock price. During the year ended December 31, 2014, we recognized a gain of $198,000 due to the decrease in value of this note. The amounts used in computing the purchase price differ from the amounts in the purchase agreements due to fair value measurement conventions prescribed in accounting standards.

The transaction is being accounted for using the acquisition method of accounting for business combinations in accordance with GAAP. Under this method, the total consideration transferred to consummate the acquisition is being allocated to the identifiable tangible and intangible assets acquired and liabilities assumed based on their respective fair values as of the closing date of the acquisition. The acquisition method of accounting requires extensive use of estimates and judgments to allocate the consideration transferred to the identifiable tangible and intangible assets acquired and liabilities assumed. Accordingly, the allocation of the consideration transferred in the consolidated financial statements is preliminary and will be adjusted upon completion of the final valuation of the assets acquired and liabilities assumed. The final valuation of fixed assets and intangibles is expected to be completed as soon as practicable but no later than twelve months after the closing date of the acquisition.

The preliminary allocation of the total purchase price to the fair value of the assets acquired and liabilities assumed as of August 18, 2014 are as follows:

	Amount
Accounts receivable	$	151,002
Other current assets	120,528
Fixed Assets	624,948
Other assets	416,869
Goodwill	541,565
Current liabilities	(758,614		)
Other liabilities	(22,049		)
Total Purchase Price	$	1,074,249

The following table provides certain proforma financial information for the Company as if the acquisitions discussed above occurred on January 1, 2012:

	Unaudited
	Year Ended December 31,

The results of operations for the twelve months endedDecember 31, 2014 include the operations of Gentris from July 16, 2014 and BioServe from August 18, 2014 and include combined revenues of $3,296,465 and a combined net loss of $1,438,118.

Reverse Stock Splits

On February 8, 2013, we filed a charter amendment with the Secretary of State for the State of Delaware and effected a 1-for-2 reverse stock split of our common stock. On March 1, 2013, we filed another charter amendment with the Secretary of State for the State of Delaware and effected a 1-for-2.5 reverse stock split of our common stock. All shares and per share information referenced throughout the consolidated financial statements have been retroactively adjusted to reflect both reverse stock splits.

Public Offerings

On April 10, 2013, we sold 690,000 shares of common stock at a public offering price of $10.00 per share and completed our initial public offering (“IPO”) with gross proceeds of $6.9 million (net proceeds of $5 million). Upon the closing of the IPO, all shares of our then-outstanding Series A and Series B convertible preferred stock automatically converted into an aggregate of 1,287,325 shares of common stock. Concurrent with the IPO, certain derivative warrants with a fair value of $7.2 million were reclassified into equity due to the lapsing of anti-dilution provisions in the warrants. Also concurrent with the IPO, $9.6 million of debt converted into 963,430 shares of common stock. All references to our Series A convertible preferred stock refer collectively to the Series A and Series A-1 convertible preferred shares.

On August 19, 2013, we sold 1,500,000 shares of common stock at a public offering price of $10.00 per share resulting in gross proceeds of $15.0 million (net proceeds of $13.3 million). We used $3.5 million of the proceeds to repay certain indebtedness which was due on August 15, 2013 (see Note 6 for further discussion of the Company’s debt). On September 5, 2013, we sold 105,000 additional common shares pursuant to partial exercise of the underwriter’s over-allotment option which resulted in gross proceeds of $1.1 million (net proceeds of $947,000). All references to the sales of common stock mentioned in this paragraph are referred to as the “Secondary Offering.”

On October 28, 2013, we sold 3,286,700 shares of common stock, (including the underwriter’s overallotment of 428,700 shares), at a public offering price of $14.00 per share resulting in gross proceeds of $46.0 million (net proceeds of $42.3 million). All references to the sales of common stock mentioned in this paragraph are referred to as the “Follow-On Offering.”

Stock Option Plans

Stock Option Plans

We have two equity incentive plans: the 2008 Stock Option Plan (the “2008 Plan”) and the 2011 Equity Incentive Plan (the “2011 Plan”, and together with the 2008 Plan, the “Stock Option Plans”). The Stock Option Plans are meant to provide additional incentive to officers, employees and consultants to remain in our employment. Options granted are generally exercisable for up to 10 years.

The Board of Directors adopted the 2011 Plan on June 30, 2011 and reserved 350,000 shares of common stock for issuance under the 2011 Plan. On May 22, 2014, the stockholders voted to increase the number of shares reserved by the plan to 2,000,000 shares of common stock under several types of equity awards including stock options, stock appreciation rights, restricted stock awards and other awards defined in the 2011 Plan.

The Board of Directors adopted the 2008 Plan on April 29, 2008 and reserved 251,475 shares of common stock for issuance under the plan. On April 1, 2010, the stockholders voted to increase the number of shares reserved by the plan to 550,000. We are authorized to issue incentive stock options or non-statutory stock options to eligible participants.

We have also issued 48,000 options outside of the Stock Option Plans.

At December 31, 2014, 386,044 shares remain available for future awards under the 2011 Plan and 89,051 shares remain available for future awards under the 2008 Plan.

As of December 31, 2014, no stock appreciation rights and 227,500 shares of restricted stock had been awarded under the Stock Option Plans.

Prior to our IPO in April 2013, the Board of Directors authorized an offer to certain employee and non-employee options holders on the following terms: those holding stock options with a strike price of $25.00 or more had the opportunity to exchange their options for 60% of the number of options currently held with an exercise price equal to the IPO price, which was $10.00 per share, and those holding stock options with a strike price of $12.50 had the opportunity to exchange their options for 80% of the number of options currently held with an exercise price equal to the IPO price which was $10.00 per share. On April 5, 2013, our initial public offering became effective and 336,300 options with exercise prices ranging from $12.50 to $33.80 were exchanged for 242,070 options with an exercise price of $10.00. The options did not result in the recognition of incremental compensation cost. In addition, 53,500 options which were approved to be issued and priced at the IPO price were issued to employees with an exercise price of $10.00 per share.

A summary of employee and non-employee stock option activity for the years ended December 31, 2014, 2013 and 2012 is as follows:

	Options Outstanding				Weighted- Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value
	Number of Shares		Weighted- Average Exercise Price
Outstanding January 1, 2012	559,990		$	12.85	8.10	$	11,737,710

Exercisable, December 31, 2014	635,435		$	9.14	6.72	$	478,219

Aggregate intrinsic value represents the difference between the fair value of our common stock and the exercise price of outstanding, in-the-money options. The fair value of our common stock was $6.68 and $13.78 as of December 31, 2014 and 2013, respectively, and the estimated fair value of our common stock was $9.60 as of December 31, 2012. During the year ended December 31, 2014 and 2013, we received $79,018 and $1,640, respectively from the exercise of options. Also during the year ended December 31, 2014, an option holder exercised options to purchase 12,000 shares of common stock with an exercise price of $10.00 per share using the net issue exercise method whereby the option holder surrendered 11,429 shares in payment in full of the exercise price resulting in net issuance of 571 shares of common stock. The options exercised in 2014 and 2013 had a total intrinsic value of $120,510 and $1,630, respectively. Options were not exercised in 2012.

As of December 31, 2014, total unrecognized compensation cost related to non-vested stock options granted to employees was $6,058,774, which we expect to recognize over the next 3.70 years.

As of December 31, 2014 and 2013, total unrecognized compensation cost related to non-vested stock options granted to non-employees was $645,739 and $94,359, respectively, which we expect to recognize over the next 2.95 and 1.78 years, respectively. The estimate of unrecognized non-employee compensation is based on the fair value of the non-vested options as of December 31, 2014 and 2013.

The following table summarizes information about outstanding and vested stock options granted to employees and non-employees as of December 31, 2014 as follows:

	Options Outstanding				Options Vested and Exercisable

The fair value of options granted to employees is estimated on the grant date using the Black-Scholes option valuation model. This valuation model for stock-based compensation expense requires us to make assumptions and judgments about the variables used in the calculation, including the fair value of our common stock (see Note 13), the expected term (the period of time that the options granted are expected to be outstanding), the volatility of our common stock, a risk-free interest rate, and expected dividends. We also estimate forfeitures of unvested stock options. To the extent actual forfeitures differ from the estimates, the difference will be recorded as a cumulative adjustment in the period estimates are revised. No compensation cost is recorded for options that do not vest. We use the simplified calculation of expected life described in the SEC’s Staff Accounting Bulletin No. 107, Share-Based Payment, and volatility is based on an average of the historical volatilities of the common stock of three entities with characteristics similar to those of the Company. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option. We use an expected dividend yield of zero, as we do not anticipate paying any dividends in the foreseeable future. Expected forfeitures are assumed to be zero due to the plan design which has monthly vesting after an initial cliff vesting period.

The following table presents the weighted-average assumptions used to estimate the fair value of options granted to employees during the periods presented:

	Year Ended December 31,
	2014			2013			2012
Volatility	70.17		%	76.60		%	77.39		%

Term (years)	5.98			6.14			6.50
Weighted-average fair value of options granted during the period	$	5.29		$	9.85		$	23.35

In 2010, we issued an aggregate of 80,000 options to non-employees with an exercise price of $25.00. As described above, on April 5, 2013, these options were exchanged for 48,000 options with an exercise price of $10.00. In October 2013, we issued 10,000 options to a non-employee with an exercise price of $15.39. In May 2014, we issued 200,000 options to a Director, with an exercise price of $15.89. See Note 17 for additional information. The following table presents the weighted-average assumptions used to estimate the fair value of options reaching their measurement date for non-employees during the periods presented:

	Year Ended December 31,
	2014		2013		2012

Dividend yield	—		—		—
Term (years)	9.68		7.68		8.28

Starting in 2013, restricted stock awards have been granted to employees, directors and consultants as compensation for services. At December 31, 2014, there was $852,206 of unrecognized compensation cost related to non-vested restricted stock granted to employees; we expect to recognize the cost over 3 years. At December 31, 2014, there was $12,948 of unrecognized compensation cost related to non-vested restricted stock granted to non-employees, which we expect to recognize over 0.78 years.

The following table summarizes the activities for our non-vested restricted stock awards for the years ended December 31, 2014 and 2013:

	Non-vested Restricted Stock Awards
	Number of Shares			Weighted-Average Grant Date Fair Value
Non-vested at January 1, 2013	$	—		$	—

Warrants and Rights Note Disclosure [Abstract]

Warrants

Warrants

We have issued certain warrants which contain an exercise price adjustment feature in the event we issue additional equity instruments at a price lower than the exercise price of the warrant. The warrants are described herein as derivative warrants. For all derivative warrants, in the event equity instruments are issued at a price lower than the exercise price of the warrant, the exercise price is adjusted to the price of the new equity instruments issued (price adjustment feature). For certain of these warrants, the number of shares underlying the warrant is also adjusted to an amount computed by dividing the proceeds of the warrant under its original terms by the revised exercise price (share adjustment feature). These warrants are initially recorded as a warrant liability at fair value with a corresponding entry to the loan guarantee fee asset, debt discount, additional paid-in capital or expense dependent upon the service provided in exchange for the warrant grant. Subsequently, any change in fair value is recognized in earnings until such time as the warrants are exercised, amended or expire. As of December 31, 2014 all warrants with a share adjustment feature have either expired or have been exercised.

In connection with debt guarantees and extensions, we issued 1,051,506 warrants to Mr. Pappajohn, a member of our Board of Directors and stockholder, at various dates (see Note 17). These warrants were initially recorded at fair value as a loan guarantee fee amortized over the period of the guarantee to interest expense. The aggregate issue date fair value of the debt guarantee warrants was $1,555,000 in 2012, and $831,000 in 2011. There were no debt guarantee warrants issued in 2014 or 2013.

In connection with the acquisition of a line of credit, we issued 60,000 warrants to DAM in March 2011 with an initial estimated fair value of $1,019,000.

On September 6, 2012, we extended the maturity date of warrants to purchase 70,598 shares of our common stock which were due to expire on September 10, 2012 to September 28, 2012. On September 27, 2012, we extended the maturity date of 65,328 of these warrants to September 10, 2013. In exchange, the warrants became subject to a lock-up agreement for 180 days after the consummation of an IPO on the same terms as other lock-up agreements in favor of the underwriters of an offering. We determined the fair value of the warrant extensions to be approximately $144,000, which was recorded as general and administrative expense.

On October 22, 2012, in exchange for amending warrants issued in connection with his guarantee of the Wells Fargo debt, we issued warrants to purchase 10,157 shares of our common stock to Mr. Pappajohn with an exercise price equal to the lesser of (i) $42.50 per share and (ii) the IPO or merger price per share.

Pursuant to a subsequent agreement, the warrants held by Mr. Pappajohn have an exercise price of $15.00 per share.

In connection with the December 2012 Bridge Financing Transaction, we granted 2,353ten-year warrants with an exercise price equal to the IPO price of $10.00 per share to Mr. Pappajohn on March 7, 2013. Mr. Pappajohn subsequently agreed that if our final IPO price was below $15.00, there would be no further adjustment to the price or number of shares covered by the warrants held by him. These warrants were initially recorded at fair value as a financing fee asset and were amortized over the period of the note to interest expense. The issue date fair value of these warrants was $47,000.

On February 11, 2013, John Pappajohn agreed to limit certain anti-dilution rights in his warrants to purchase shares of the Company’s common stock. Subject to the consummation of an IPO prior to April 13, 2013, Mr. Pappajohn agreed that if the final IPO price was below $15.00, the exercise price of the warrants held by him would adjust to $15.00 and the number of shares underlying the warrants would be adjusted as if the IPO price were $15.00 and then there would be no further adjustment to the price or number of shares covered by warrants held by him. In February 2013, certain warrant holders agreed to waive the price and share adjustment provisions of their warrants, except for the anti-dilution provisions related to stock splits, subdivisions and combinations, with respect to an aggregate of 114,030 shares of common stock underlying such warrants, effective immediately following the consummation of our IPO on April 10, 2013 at $10.00 per share.

Business Line of Credit — Wells Fargo

At December 31, 2014 and 2013, we have fully utilized a line of credit with Wells Fargo Bank which provides for maximum borrowings of $6 million. On April 1, 2014 we entered into a credit agreement and re-negotiated the terms of our fully utilized line of credit with Wells Fargo Bank. The line of credit was extended through April 1, 2016 at a rate of interest equal to the Daily One Month LIBOR rate plus 1.75% (1.91% at December 31, 2014). The facility requires monthly interest payments.

The line of credit is collateralized with $6 million in cash. Additionally, we are required to maintain limits on capital spending and are restricted as to the amount we may pledge as collateral for additional borrowings from any source. The line of credit requires the repayment of principal, and any unpaid interest, in a single payment due upon maturity.

Conversion of Debt concurrent with IPO

On April 10, 2013, we completed our IPO and converted the following indebtedness into shares of common stock at the IPO price of $10.00 per share:

	Converted Amount		Common Shares
December 2011 Financing Transaction	$	4,500,000	450,000
2012 Convertible Debt Financing Transaction	3,000,000		300,000
December 2012 Bridge Financing Transaction	1,000,000		100,000
Business Lines of Credit (DAM)	1,000,000		100,000
Other Note Payable and accrued interest	134,300		13,430
	$	9,634,300	963,430

In connection with the conversion of debt into common stock, we expensed the applicable remaining debt discounts of $3.5 million, financing fees of $419,000 and a contingently recognizable beneficial conversion feature in the converted debt of $3 million.

December 2011 Financing Transaction

The December 2011 Credit Agreement was with John Pappajohn and Andrew Pecora (indirectly through an investment company), both then members of our board of directors, and NNJCA Capital, LLC (“NNJCA”), a limited liability company of which Dr. Pecora is a member. Mr. Pappajohn originally provided $4.0 million of financing, NNJCA originally provided $1.5 million of financing and Dr. Pecora provided $500,000 of financing under the Credit Agreement. On April 10, 2013, Mr. Pappajohn converted $4.0 million and Dr. Pecora converted $500,000 into 450,000 shares of our common stock at the IPO price of $10.00 per share concurrent with our IPO. The remaining outstanding balance of $1.5 million was repaid on August 19, 2013 using a portion of the proceeds from our Secondary Offering.

2012 Convertible Debt Financing Transaction

On April 10, 2013, the entire $3 million outstanding under a Restated Credit Agreement dated as of August 27, 2012, as amended and restated as of October 17, 2012, ($1,750,000 provided by Mr. Pappajohn and $1,250,000 provided by Mr. Mark Oman) was converted into 300,000 shares of common stock at the IPO price of $10 per share.

December 2012 Bridge Financing Transaction

On April 10, 2013, the entire $1 million outstanding under a credit agreement dated as of December 7, 2012, (all of which was provided by Mr. Pappajohn), was converted into 100,000 shares of common stock at the IPO price of $10.00 per share.

Business Line of Credit – DAM

On April 10, 2013, $1 million of indebtedness under this line was converted into 100,000 shares of common stock at the IPO price of $10 per share. The remaining outstanding balance of $2.0 million was repaid on August 19, 2013 using a portion of the proceeds from our Secondary Offering.

Other Note Payable

On April 10, 2013, a $100,000 note payable and accrued interest payable to Dr. Chaganti was converted into 13,430 shares of common stock at the IPO price of $10.00 per share.

Loss on Debt and Warrant Restructuring

We entered into a Restated Credit Agreement with Mr. Pappajohn and Mr. Oman in October 2012 to provide for additional borrowing of $1,000,000, which agreement also removed the conversion price adjustment of a 20% discount to the IPO or merger price if the IPO or merger price is less than $53.12 per share. We evaluated the application of ASC 470-50, Modifications and Extinguishments and ASC 470-60, Troubled Debt Restructurings by Debtors and concluded that the revised terms constituted a debt extinguishment, rather than a debt modification or troubled debt restructuring.

We cancelled certain warrants with an exercise price adjustment of a 20% discount to the IPO or merger price if the IPO or merger price is less than $53.13 per share and issued warrants without an exercise price adjustment to a 20% discount to the IPO or merger price if the IPO or merger price is less than $53.13 per share as compensation. In connection with these transactions, we recognized a loss on debt and warrant restructuring during 2012 as presented below:

Restated 2012 convertible debt financing transaction	$	1,506,512
Amend warrants granted for guarantee of business line of credit	268,000

John Pappajohn, a member of the Board of Directors and stockholder, had personally guaranteed our revolving line of credit with Wells Fargo Bank through March 31, 2014. As consideration for his guarantee, as well as each of the eight extensions of this facility through March 31, 2014, Mr. Pappajohn received warrants to purchase an aggregate of 1,051,506 shares of common stock of which Mr. Pappajohn assigned warrants to purchase 284,000 shares of common stock to certain third parties. Through December 31, 2014, warrants to purchase 440,113 shares of common stock have been exercised by Mr. Pappajohn and 233,333 warrants to purchase common stock have expired. After adjustment pursuant to the terms of the warrants in conjunction with our IPO, the number of these warrants outstanding retained by Mr. Pappajohn was 352,312 at $15.00 per share on December 31, 2014.

In addition, John Pappajohn also had loaned us an aggregate of $6,750,000 (all of which was converted into 675,000 shares of common stock at the IPO price of $10.00 per share). In connection with these loans, Mr. Pappajohn received warrants to purchase an aggregate of 202,630 shares of common stock. After adjustment pursuant to the terms of the warrants in conjunction with our IPO, the number of warrants outstanding was 436,079 at $15.00 per share at December 31, 2014.

Effective January 6, 2014, the board of directors appointed John Pappajohn to serve as the Chairman of the Board, a position previously held by Dr. Raju S.K. Chaganti. As compensation for serving as the Chairman of the Board, the Company will pay Mr. Pappajohn $100,000 per year and granted to Mr. Pappajohn 25,000 restricted shares of the Company's common stock, and options to purchase an aggregate of 100,000 shares of the Company's common stock. The options have a term of ten years from the date on which they were granted. The restricted stock and the options each vest in two equal installments on the one year anniversary and the two year anniversary of the date on which Mr. Pappajohn became the Chairman of the Board.

In August 2010, we entered into a consulting agreement with Equity Dynamics, Inc. (“EDI”), an entity controlled by John Pappajohn, pursuant to which EDI received a monthly fee of $10,000. The consulting agreement was terminated effective March 31, 2014. Subsequently the Company entered into a new consulting agreement with EDI effective April 1, 2014 pursuant to which it will receive a monthly fee of $10,000. We expensed $120,000 annually for the years ended December 31, 2014, 2013 and 2012 related to this agreement.

On May 19, 2006, we issued a convertible promissory note in favor of our then Chairman and founder, Dr. Chaganti, the holder, which obligated us to pay the holder the sum of $100,000, together with interest at the rate of 8.5% per annum, due April 1, 2014. Interest expense was $2,400 and $8,400 for the years ended December 31, 2013 and 2012, respectively. On April 10, 2013 the note and accrued interest converted into 13,430 shares of common stock at the IPO price of $10.00 per share. Pursuant to a consulting and advisory agreement, Dr. Chaganti also received options to purchase a total of 36,000 shares of common stock at a price of $10.00 per share which vested over a two year period. Total non-cash stock-based compensation recognized under the consulting agreement for the years ended December 31, 2014, 2013 and 2012 was $0, $76,220 and $430,600, respectively. Additionally, on September 15, 2010, we entered into a three year consulting agreement with Dr. Chaganti which was subsequently renewed through December 31, 2016 pursuant to which Dr. Chaganti receives $5,000 per month for providing consulting and technical support services. Total expenses for each of the years ended December 31, 2014, 2013 and 2012 were $60,000. Pursuant to the terms of the renewed consulting agreement, Dr. Chaganti received an option to purchase 200,000 shares of our common stock at a purchase price of $15.89 per share vesting over a period of four years. Total non-cash stock-based compensation recognized under this consulting agreement for the years ended December 31, 2014, 2013 and 2012 were $341,000, $0 and $0. Also pursuant to the consulting agreement, Dr. Chaganti assigned to us all rights to any inventions which he may invent during the course of rendering consulting services to us. In exchange for this assignment, if the USPTO issues a patent for an invention on which Dr. Chaganti is listed as an inventor, we are required to pay Dr. Chaganti (i) a one-time payment of $50,000 and (ii)1% of any net revenues we receive from any licensed sales of the invention. In 2014 we paid Dr. Chaganti $150,000 which was recognized as an expense in fiscal 2013 when three patents were issued. Also in February 2015, we paid Dr. Chaganti $150,000 for which was recognized as an expense in 2014 when three additional patents were issued.

Andrew Pecora (indirectly through an investment company), when a member of our board of directors, and NNJCA, a limited liability company of which Dr. Pecora is a member originally provided $0.5 and $1.5 million of financing, respectively, under a Credit Agreement dated as of December 21, 2011, as amended and restated as of February 13, 2012. On April 10, 2013, NNJCA converted $0.5 million of its outstanding indebtedness into 50,000 shares of our common stock at the IPO price of $10.00 per share concurrent with our IPO. On August 19, 2013, the remaining principal under these notes were repaid to Dr. Pecora and NNJCA using a portion of the proceeds from our Secondary Offering. The loan bore an annual interest rate equal to the prime rate plus 6.25% (9.50% at August 19, 2013). We paid a pre-payment penalty due to Pecora and NNJCA of $130,000 of which $32,667 was paid upon conversion of the notes and the remaining balance paid on August 19, 2013.

On August 15, 2010, we entered into a two-year consulting agreement with Dr. Pecora, then a member of our board of directors, pursuant to which Dr. Pecora received $5,000 per month for providing consulting and advisory services. The cash component of this agreement was terminated by mutual consent in August 2011. Dr. Pecora also received stock options under the consulting and advisory agreement to purchase a total of 12,000 shares of common stock at price of $25.00 per share which vested over a two year period. Total expenses for 2014, 2013 and 2012 under the consulting agreement were $0 , $0, $142,740, respectively, expensed under the stock option plan.

In February 2012, we granted 28,235 warrants proportionately to Pecora and NNJCA upon their funding of $0.5 million and $1.5 million, respectively, under a new Credit Agreement. (See Notes 6 and 12). On May 15, 2012 and on August 14, 2012, we issued 4,706 of these warrants proportionately to Pecora and NNJCA (Notes 6 and 12). On October 15, 2012, Dr. Pecora and NNJCA agreed to surrender warrants to purchase an aggregate of 37,646 shares of our common stock issued in connection with this transaction in exchange for an amendment to increase the pre-payment penalties by $130,000.

Fair Value of Warrants

The following tables summarize the assumptions used in computing the fair value of derivative warrants subject to fair value accounting at the date of issue during the years ended December 31, 2014, 2013 and 2012 and at December 31, 2014, December 31, 2013 and April 5, 2013 (IPO valuation date). In computing the fair value of the warrants, if the stated exercise price of the warrants exceeded the assumed value of the Company stock at the date the fair value was being computed, the exercise price and number of shares (if applicable) underlying the warrants were adjusted to reflect an assumed trigger of the price and/or share adjustment features related to the applicable warrants. Such adjustments were only applicable to 2012 and 2013 due to the relative price of the warrants and the assumed Company stock price:

The assumed ranges of Company stock prices used in computing the warrant fair value for warrants issued during the year is as follows: in 2014, $6.68—$19.86; in 2013, $9.60—$20.26; in 2012, $9.60—$33.80. In determining the fair value of warrants issued at each reporting date, the assumed Company stock price was $6.68 and $13.78 (the closing price on the NASDAQ Capital Market) at December 31, 2014 and 2013.

During January and December 2014, we sold $28,640,223 of gross State of New Jersey NOL carryforwards relating to tax years 2009 through 2012, resulting in the receipt of $2,350,185. During 2013, we sold $8,018,107 of gross State of New Jersey NOL carryforwards, resulting in the receipt of $663,900.

We transferred the NOL carryforwards through the Technology Business Tax Certificate Transfer Program sponsored by the New Jersey Economic Development Authority.

Approximate deferred taxes consist of the following components as of December 31, 2014 and 2013:

Deferred tax liabilities:

Due to a history of losses we have generated since inception, we believe it is more-likely-than-not that all of the deferred tax assets will not be realized as of December 31, 2014 and 2013. Therefore, we have recorded a full valuation allowance on our deferred tax assets. We have net operating loss carryforwards for federal income tax purposes of approximately $57,000,000 as of December 31, 2014. The net operating loss carryforwards will begin to expire in 2027. Utilization of these carryforwards is subject to limitation due to ownership changes that may delay the utilization of a portion of the carryforwards.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The Fair Value Measurements and Disclosures Topic of the FASB Accounting Standards Codification requires the use of valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect our own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In that regard, the Topic establishes a fair value hierarchy for valuation inputs that give the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs.

The fair value hierarchy is as follows:

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that we have the ability to access as of the measurement date.

Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

Level 3: Significant unobservable inputs that reflect our own assumptions about the assumptions that market participants would use in pricing an asset or liability.

The following table summarizes the financial liabilities measured at fair value on a recurring basis segregated by the level of valuation inputs within the fair value hierarchy utilized to measure fair value:

	2014
	Total		Quoted Prices in Active Markets for Identical Assets (Level 1)	Significant Other Observable Inputs (Level 2)	Significant Unobservable Inputs (Level 3)
Warrant liability	$	52,000	—	—	$	52,000
Gentris contingent consideration	293,400		—	—	293,400
Notes payable to VenturEast	534,828		—	—	534,828
	$	880,228	—	—	$	880,228
	2013
	Total		Quoted Prices in Active Markets for Identical Assets (Level 1)	Significant Other Observable Inputs (Level 2)	Significant Unobservable Inputs (Level 3)
Warrant liability	$	594,000	—	—	$	594,000

The warrant liability consists of stock warrants we issued that contain an exercise price adjustment feature. In accordance with derivative accounting for warrants, we calculated the fair value of warrants and the assumptions used are described in Note 13, “Fair Value of Warrants”. Realized and unrealized gains and losses related to the change in fair value of the warrant liability are included in other income (expense) on the Consolidated Statement of Operations.

The value of the Gentris contingent consideration was determined using a discounted cash flow of the expected payments required by the purchase agreement.

The ultimate payment to VenturEast will be the value of 84,278 shares of common stock at the time of payment. The value of the note payable to VenturEast was determined using the fair value of our common stock less a discount for credit risk. During the year ended December 31, 2014 we recognized a gain of $198,000 due to the decrease in value of the note. Realized and unrealized gains and losses related to the change in fair value of the note are included in other income (expense) on the Consolidated Statement of Operations.

A table summarizing the activity for the derivative warrant liability which is measured at fair value using Level 3 inputs is presented in Note 13. The following table summarizes the activity of the notes payable to VenturEast and Gentris contingent consideration which were measured at fair value using Level 3 inputs:

	Note Payable			Gentris Contingent
	to VenturEast			Consideration
Fair value at January 1, 2014	$	—		$	—
Fair value at issuance	733,387			293,400
Change in fair value	(198,559		)	—
Fair value at December 31, 2014	$	534,828		$	293,400
