Business.OverviewWe are a commercial stage company that develops and markets products and services based on proprietary technology that facilitates the routine useof targeted molecular profiling using a small amount of biological sample. Molecular profiling is the collection of information about multiple moleculartargets, such as DNA and RNA, also called biomarkers, in a biological sample. Molecular profiling information has many important applications, from basicresearch to molecular diagnostics in personalized medicine. Our technology can be used throughout that range of applications, which is just one of its manybenefits. Our focus is on clinical applications. Our primary customers include biopharmaceutical companies, academic research centers and molecular testinglaboratories.As part of our business model, we seek to leverage key business drivers in molecular profiling, including the acceleration of precision medicine, themigration of molecular testing to next generation sequencing, the movement to less invasive biopsies, the need for greater diagnostic sensitivity, the need toconform to changing healthcare economics and the need for automation and an easily deployable workflow. Our products include instrumentation (orplatforms), consumables, including assay kits, and software analytics that, as an integrated system, automate sample processing and can quickly, robustly andsimultaneously profile tens, hundreds or thousands of molecular targets from samples a fraction of the size required by prevailing technologies. Our objectiveis to establish our solutions as the standard in molecular profiling, and to make their benefits accessible to all molecular labs from research to the clinic. Webelieve that our target customers desire high quality molecular profiling information in a multiplexed panel format from increasingly smaller and lessinvasive samples, with the ability to collect such information locally to minimize turnaround time and cost.Historically, molecular profiling has faced several technical challenges in clinical applications. These include (i) limited “multiplexing,” which meansonly a few biomarkers could be tested in a single sample, (ii) the need for significant amounts of sample to test more than a few biomarkers, which oftenrequired several different technologies conducted in different locations, (iii) complex sample preparation, and (iv) manual and/or time consuming workflows.Even where it was possible to test tens, hundreds or thousands of biomarkers, such as with fixed arrays, data analysis could be quite complicated and timeconsuming.Our proprietary technology has several key differentiators, including (i) multiplexing from tens to thousands of biomarkers in a single sample, (ii) verylow sample input requirements, (iii) simple, extraction-free sample preparation, which is effective with a wide variety of samples including formalin fixedparaffin-embedded (“FFPE”) tissue and liquid biopsies, (iv) automated workflow with sample-to-result turnaround times rivaling any current competitor, and(v) simplified data output. In addition, our HTG EdgeSeq assay technology, launched in 2014, generates a molecular profiling library for detection usingNGS instrumentation. Among other things, NGS provides improved sensitivity and dynamic range for our HTG EdgeSeq assays. We believe these advantagesposition us to outperform most other now-available molecular profiling technologies, especially in certain sample types, such FFPE. While we continue toadvance our technology, we are particularly focused on gaining market recognition and expanding our product offerings.We currently have two primary sources of revenue: revenue from research use only (“RUO”) profiling for biopharmaceutical companies, academicresearch centers and molecular testing laboratories; and revenue from collaborative development services for companion diagnostic development programsfor biopharmaceutical companies. RUO profiling revenue includes customer purchases of our HTG EdgeSeq instrument and integrated RUO assay kits, andthe use of our HTG EdgeSeq instruments and RUO assay kits to process samples on the customer’s behalf in our VERI/O laboratory. Collaborativedevelopment services revenue relates to services performed primarily for biopharmaceutical companies pursuant to our Master Assay Development,Commercialization and Manufacturing Agreement (the “Governing Agreement”) with QIAGEN Manchester Limited (“QML”), a wholly owned subsidiary ofQIAGEN N.V. Under the Governing Agreement, whereby our HTG EdgeSeq proprietary technology is utilized to develop, seek regulatory approval for andcommercialize clinical diagnostic assays for biopharmaceutical drug candidates and corresponding therapeutics.Our assay offerings that are currently sold for research use only include the following: •HTG EdgeSeq Oncology Biomarker Panel; •HTG EdgeSeq Immuno-Oncology Assay; •HTG EdgeSeq DLBCL Cell of Origin Assay; •HTG EdgeSeq PATH Assay; •HTG EdgeSeq miRNA Whole-Transcriptome Assay; and •HTG EdgeSeq EGFR, KRAS and BRAF Mutation Assay (VERI/O lab service offering exclusively).2In addition, we have obtained CE-marking for two of our assay offerings in Europe, making the following assay products available for diagnostic usein Europe: •HTG EdgeSeq ALKPlus Assay EU; and •HTG EdgeSeq DBLCL Cell of Origin Assay EU.We continue work on our pre-market approval (“PMA”) submission for our HTG EdgeSeq ALKPlus Assay in the United States. We also have a focuseddevelopment pipeline of new profiling products, which includes planned panels for translational research, drug development, and molecular diagnostics withinitial focus in immuno-oncology. Our HTG EdgeSeq EGFR, KRAS and BRAF Mutation Assay is our first commercially available application based on thenext generation of our HTG EdgeSeq chemistry.Our HTG EdgeSeq assays are automated on our HTG EdgeSeq platform, which may also be referred to as an “instrument” or “processor” and which,together with the assay, is a fully integrated system.Customers can obtain the advantages of our proprietary technology by engaging our VERI/O laboratory for pre-clinical and clinical research-relatedservices, including drug development and translational research. Our services include processing samples for molecular profiling data and designing customresearch or investigational profiling assays. We also perform collaborative development services for biopharmaceutical company customers, primarilythrough the Governing Agreement with QML.We believe the value propositions of our products and services are gaining significant recognition. In 2016, we entered into an RUO servicesagreement with Bristol-Myers Squibb Company (“BMS”) and a collaborative development services agreement with Merck KGaA, Darmstadt, Germany(“Merck KGaA”). In June 2017, we entered into our first statement of work (“SOW One”) under the Governing Agreement relating to a companion diagnosticprogram for a biopharmaceutical partner, and subsequently entered into two additional statements of work in October 2017 (“SOW Two”) and January 2018(“SOW Three”), relating to companion diagnostic programs for two additional biopharmaceutical company customers. In December 2017, we entered into aseparate RUO services agreement for development and manufacturing of RUO assays supporting biomarker research programs with Merck KGaA. Theseprograms represent just a few of the over 30 individual project programs with biopharmaceutical companies employing our proprietary technology in theirclinical research and drug development programs as of December 31, 2017.As we navigate product-related regulatory requirements to launch additional molecular diagnostic products, initially in Europe and then in the UnitedStates, we expect our RUO products and services will continue to drive market recognition and technology adoption. Further, we believe that strategicallypositioning our proprietary technology, products and services in drug or other clinical development programs will drive a future, ongoing portfolio ofmolecular diagnostic products, including companion diagnostic products.Our StrategyOur objective is to establish the HTG solutions as the standard in molecular profiling, and to make their benefits accessible to all molecular labs fromresearch to the clinic. The key components of our strategy are: •Focus on immuno-oncology based molecular profiling. We plan to develop novel RNA-based gene classifiers to help biopharmaceuticalcompanies and leading translational medicine researchers better understand and predict durable response to immune checkpoint inhibitor drugcandidates, such as anti-PD-L1 therapeutics, in mono- and combination therapies. We also plan to develop novel DNA profiling tests (usingRNA surrogate assays) that can provide information about mutation load and microsatellite instability, which are genetics factors believed tobe associated with response to immune checkpoint inhibitor therapies. •Increase and strengthen companion diagnostics collaborations with biopharmaceutical companies. We believe collaborations withbiopharmaceutical companies with late-stage drug development programs will lead to us generating companion diagnostic consumablesrevenue. As of December 31, 2017, we had 37 active development programs across 9 leading biopharmaceutical companies which areincorporating companion diagnostics in their drug development programs. Through our Governing Agreement with QML, we have initiatedcompanion diagnostic collaborative development services for three biopharmaceutical company programs to date, in addition to our existingarrangement with Merck KGaA from 2016. We intend to continue to leverage our VERI/O laboratory services business to enable nimbleresponse to emerging biopharmaceutical molecular profiling requirements.3 •Increase our market adoption by leveraging the advantages of our technology, including low sample input and high sensitivity. We plan topromote global adoption of our proprietary technology in molecular labs, biopharmaceutical companies and major translational researchcenters by demonstrating the key differentiating aspects of our chemistry and platforms, such as small sample utilization, multiplexing andhigh sensitivity. These advantages result in cost, time and ease of use benefits for our customers. To facilitate adoption, our VERI/O servicelaboratory, supports customers who desire additional laboratory capacity, assay design services, and/or to access our service-only contentofferings. We also continue to offer our HTG EdgeSeq system and reagents to customers who want to bring our technology in-house. •Establish our systems workflow as the best solution for clinical sequencing. We intend to continue to establish our technology as the bestsample and library preparation method for clinical applications with next generation sequencers. We believe our differentiated HTG EdgeSeqchemistry will accelerate adoption by leveraging the large and growing installed base of next generation sequencers. We are engaged withindustry and corporate partners including Illumina, Life Technologies Corporation and QML, to position our HTG EdgeSeq products as thebenchmark for workflow in targeted sequencing applications. •Develop new molecular diagnostic panels with high medical utility. Our HTG EdgeSeq platform was developed with features that we believewill enable local molecular labs to routinely test targeted RNA expression, including expressed gene mutations, such as ALK generearrangements using our HTG EdgeSeq ALKPlus Assay, all from extremely small samples, such as a single five-micron section of FFPE tissue.We plan to develop future molecular diagnostic assays in conformance with existing reimbursement codes to facilitate our clinical customers’billings. We also plan to work in the major European medical centers to develop and validate certain solid tumor classifiers and lower costalternatives for breast and prostate cancer testing. •Expand the addressable market of HTG technology through new applications. We have demonstrated technical feasibility for several newapplications that are intended to allow us to measure DNA mutations directly and in expressed RNA, and improve the already-high sensitivityof our HTG EdgeSeq assays. These new applications are expected to allow us to, among other things, develop future “multi-parameter” panelsthat detect both RNA and DNA targets in a single assay, for use in translational research, companion diagnostics and molecular diagnostics. Webelieve these applications and panels can be developed efficiently with reasonable capital investment.Our MarketDevelopment of Molecular ProfilingMolecular profiling is the analysis of biomarkers, including DNA and RNA and protein, in biological samples, such as tissue, cells, blood and otherbiofluids, to identify gene expression patterns or genomic changes. New molecular approaches are making it possible to perform these characterizations inunprecedented ways, resulting in a shift from the traditional approach of looking at one target at a time to the simultaneous analysis of potentially tens,hundreds or thousands of targets.Among what we believe are the most promising applications of molecular profiling is the targeted sequencing of RNA and DNA from patient samplesto identify gene expression patterns or molecular markers of disease that can aid in diagnosis, gauge patient prognosis or predict response to an availabletherapy. These applications have launched a fundamental shift towards personalized medicine where an individual patient’s molecular profile is used toguide treatment.We estimate that the global cancer profiling market was approximately $30.0 billion in 2017. Based on published industry reports, this market isprojected to achieve a value of $87.1 billion by 2023, with a compound annual growth rate of approximately 19.0% between 2017 and 2023. According tothese reports, the increase in demand for cancer and tumor profiling products is mainly driven by an increasing number of new cancer cases in an agingpopulation, rising utility of biomarkers in tumor profiling, rising availability of funding for cancer research and increasing demand for next generationsequencing for cancer profiling. Our initial diagnostic products target the pathology related diagnostic markets where we can transition existing testingmethods to NGS-based workflows. The companion diagnostic market is currently estimated at $2.6 billion and growing approximately 20% annually. Webelieve that the acceleration of investment into immunotherapy drugs will also be a catalyst for future companion diagnostics for combination therapieswhere gene expression classification is expected to be important.For decades, the treatment of disease was dominated by one-size-fits-all drug regimens. Over the last 10 years, numerous molecular markers andprofiling techniques have transitioned from research tools to inclusion in clinical guidelines for patient care. Oncology drug developers have also seen thebenefits of molecular markers and today there are many drugs in clinical development with a companion biomarker strategy.Among the vanguard of these personalized treatments were hormone therapies for breast cancer patients whose tumors expressed the estrogen receptorprotein. This was followed using trastuzumab for treating patients with HER2-positive breast cancers. This paradigm shift led to significantly improvedpatient outcomes when compared to the non-specific, chemotherapeutic approaches used in the past.4The evolution of molecular profiling has also taken shape over the last decade in non-small cell lung cancer (“NSCLC”). NSCLC patients were firstprofiled for EGFR gene mutations to select patients most likely to respond to the drug erlotinib. Next came testing for ALK gene rearrangements as anindicator of response to the drug crizotinib. Now, additional mutations and rearrangements such as ROS1, RET, HER2, KRAS and MET, have been integratedinto the NCCN guidelines for the treatment of lung cancer and are used to guide patient treatments.Similar trends are unfolding in other diseases such as thyroid cancer, colon cancer, and melanoma. These trends are fueling rapid growth of newmolecular profiling offerings, technologies and industry business models to support the demand. The fastest growing segment of the molecular diagnosticsmarket, a subset of the global cancer profiling market, is clinical testing in oncology. As oncologists rapidly integrate this new level of molecular profilinginformation into patient management strategies, a growing number of highly specialized central laboratories now offer tests that address specific clinicalquestions. The trend towards highly multiplexed profiling is not limited to oncology; other examples of expanding demand include prenatal, neonatal,inherited disease, and organ transplant and rejection profiling.Molecular profiling continues to move into clinical applications, including molecular profiling to develop clinical biomarker strategies, patientstratification for clinical trials, and companion diagnostics. The primary goal is to develop an understanding, at the molecular level, about why a drug does ordoes not work in a patient population. Variability in patients’ gene expression patterns is believed to at least partially explain why the 25% response rate foroncology therapeutics is among the lowest for all disease states.While the primary objective of these drug-development efforts is to improve therapeutic response rates, third-party payor pressures to lower patienttreatment costs also plays a significant role. As a result, most biopharmaceutical companies develop biomarker strategies to increase the rate of patientresponse to new drugs in development. Typically, studies will focus on a variety of biological profiling markers that include RNA or protein expressionlevels, and/or presence or absence of DNA mutations (such as gene fusions and rearrangements), which can be detected in genomic DNA or expressed RNA orprotein. Currently, it is estimated that there are over 2,000 clinical trials underway in oncology, and that the clear majority of drug developers believepersonalized and targeted therapy development is important to the future success of drug development.When a molecular biomarker panel is used for selection of patients in a Phase 2 or Phase 3 clinical trial to demonstrate safety and efficacy of a newdrug, the drug and biomarker test are often submitted to the applicable regulatory agency for approval together. In the United States, upon U.S. Food andDrug Administration (“FDA”) approval of the biomarker test, or companion diagnostic, the patient must be tested with the companion diagnostic prior totreatment with the drug. Companion diagnostic tests have a clear clinical utility which generally supports favorable reimbursement decisions. We believethere are over 900 active oncology drug development programs, most of which have molecular biomarker strategies, creating a significant opportunity formolecular diagnostic companies with the right molecular profiling solutions.Complexities and Challenges of Molecular Profiling TodayCurrently, molecular profiling typically is conducted in the clinical setting using a variety of profiling techniques and instrumentation platformsacross multiple laboratory departments, and, in many situations, sent to distant labs. These techniques include immunohistochemistry (“IHC”) fluorescent insitu hybridization (“FISH”) polymerase chain reaction (“PCR”) gene expression arrays (“GEA”) and NGS. This distributed profiling approach has acceleratedthe use of molecular profiling and increased the need to make the process more accessible and routine. However, molecular profiling is also highlyspecialized because current technologies are complex, require multiple capital-intensive workflows, and are not economically scalable to the case volume ofthe local laboratory. The fragmentation of methods, sample logistics and information flow has created significant challenges for labs, physicians and patientsas discussed below.Insufficient Sample AvailabilityThe proliferation of new molecular profiles and technologies has led to the need for more biopsy material to conduct tests of interest. However, thetrend is toward less invasive procedures that produce smaller biopsies and thus, in many situations there simply is not enough collected sample to meet allthe profiling requirements. For example, historically, the standard method of collecting tumor samples for testing in oncology is via a surgical procedurewhere the tumor is resected or biopsied and then stabilized, or fixed, in a formaldehyde-based fixative known as formalin. Between 24 to 72 hours after thetissue is removed from the patient, it is permanently stabilized in a hard block of paraffin where it can be stored at room temperature for decades. Thispreservation technique was developed over 100 years ago, well in advance of the discovery of nucleic acids such as DNA and RNA. While techniques torecover nucleic acids from these FFPE tissue samples have been developed, formalin fixation presents several technical challenges in analyzing DNA andRNA sequences. Because of the convenience of this preservation method, though, FFPE samples are the starting material for almost all tumor-profiling testingin oncology today.5Most commonly, in the past and continuing today, very thin slices of tissue from FFPE blocks, typically four to six microns in thickness, are affixed toglass slides for testing. Then, a histological stain called an H&E (for the combination of hematoxylin and eosin) is used to differentially mark cellularstructures, making it simple for a pathologist to examine the patterns of the normal and diseased tissue under a microscope. IHC stains are also oftenperformed on FFPE tissue slides to aid diagnosis, prognosis or help guide therapy selection, with each IHC stain consuming two slides, one for the stain, andthe other for a negative control. Historically, five to ten slides in total were consumed in the complete diagnostic workup for each tumor. With the advent ofnew molecular techniques there are additional demands for tissue, and most molecular tests on the market today require much more than a single slide. Inmany clinical situations, there simply is not enough collected tissue to meet all the profiling requirements. The growing number of specialized tumor-profiling tests, and their appetite for FFPE tissue or other sample material, is in direct conflict with the trend towards smaller, less-invasive testing approaches.Slow Turnaround TimesIn many cases, turnaround times for comprehensive profiling of a patient’s sample(s) are several weeks due to the logistical time to route samples tovarious laboratory departments and to distant specialized labs. Several technologies for sample characterization have been used and introduced over theyears to determine the status of various molecular characteristics for a sample. These characteristics include RNA and protein expression levels, and/or thepresence or absence of DNA mutations, such as single-point mutations and gene fusions and rearrangements, which mutations can be detected in genomicDNA or expressed RNA and protein. A single tumor specimen from a cancer patient is often profiled for multiple molecular characteristics where eachcharacteristic is measured using a different platform. These platforms are utilized in separate laboratory departments or institutions with different techniciansand clinicians, requiring that the sample and data be split into multiple workflows. This also requires even more sample consumption.The time it takes to deliver the final report to a treating physician so that informed treatment decisions may be made is dependent on the turnaroundtime of the slowest test. A single laboratory with well-choreographed routing of tissues and information may be able to complete sample profiling within aweek, but if part of the sample needs to be sent for additional profiling at a specialty lab, the total turnaround time may be lengthened by one or two weeksdue to shipping, accessioning by the receiving laboratory and integration of the testing results into the final report.Implications of Workflow Inefficiencies on Data Quality and IntegrationIn addition to the challenges of splitting a single sample into multiple testing workflows, the individual workflow for molecular profiling ofbiological samples, including FFPE tissues, is complicated. Many of the steps from sample to result require manual intervention by a molecular technician.While these technicians are trained to standard operating procedures and proficiency tested, the levels of proficiency and precision vary among technicians.Variability introduced by technicians performing manual steps can translate to variability of results, with a test sample frequently at risk of experiencinglosses of fidelity through the series of separation and transformation steps.Further, the increase in number of technologies for sample characterization and fragmentation of the testing workflows can also create challenges inputting all the results together in a timely, complete profiling report. This level of data integration is critical for the treating physicians to assure they havethe complete molecular assessment prior to consultation with the patient. Without a complete molecular assessment, there is limited ability to discuss thediagnosis, prognosis and treatment options. Overall, we believe the critical relationship between the local pathologist and treating physician has beenfractured as many tests results are now sent directly to the treating physician from these specialized and centralized Clinical Laboratory ImprovementAmendments (“CLIA”) laboratories. We believe the pathologist is critical to aggregating the diagnostic, prognostic and predictive information in a singlepatient molecular profile that can be utilized by the treating physician for therapeutic decisions.Our SolutionWe develop and sell assays, automation platforms and services based on a proprietary technology that provides precise, efficient molecular profilingof samples for clinical and research purposes. Our proprietary products and services are designed to work with many different biological sample types, cangenerate robust results from very small samples, and obviate the need for many of the sample-preparation steps associated with traditional molecular profilingtechniques. Our platforms and assays enable the simultaneous detection and quantitation of tens, hundreds or thousands of molecular targets and are capable,now or in the future, of profiling multiple parameters such as RNA expression levels, RNA-expressed gene fusions and insertions and DNA mutations in asingle testing workflow that can use NGS detection for quantitative measurement.6We manufacture the consumables utilized with our platforms specifically for our platforms and believe these consumables cannot be obtained fromother sources. At the core of our solution is our proprietary chemistry called quantitative nuclease protection (“qNPA”). Our qNPA-based chemistries providean extremely efficient method for analyzing DNA and RNA as it eliminates the need for DNA or RNA extraction or reverse transcription. We designed anddeveloped our HTG automation platforms to optimize the capabilities of our chemistries, provide fast turnaround time and enable ease of use to molecularlabs. Our chemistries and automation platforms are highly adaptable, so when molecular profiling needs change or emerge, we expect to be able to efficientlyadd new applications to address these needs.The HTG systems provide data in a simple easy to use format. The entire workflow for both systems from sample preparation to a molecular profilingreport can be accomplished in as few as 36 hours.We believe most customers in our target markets would prefer to maintain control of their samples and perform the profiling internally but arechallenged by limitations in available technologies. We believe we are well positioned to democratize molecular profiling with the following key benefits: •Optimize sample utilization. The HTG systems can analyze as many as 2,500 genes from extremely small sample volumes such as a single five-micron section of tissue or 15 microliters of plasma or serum. Our technology allows customers to do more with less, which meets the needs ofclinical or pre-clinical laboratories where today there is often not enough patient sample to do all the testing available or desired. We believeproviding customers the ability to work with extremely small sample will be a significant driver of adoption of our technology and systems. •Compatibility with multiple sample types. Our HTG systems allow customers to profile and unlock molecular information from a wide varietyof biological samples such as FFPE tissue, cells, blood serum and plasma. We have successfully demonstrated the ability to profile these andother sample types, and believe we ultimately can profile most clinically relevant sample types, including cell-free circulating nucleic acidsfrom tumors, a rapidly developing area of investigation which is referred to as a liquid biopsy. We believe that the capabilities of our systemwill allow us to efficiently expand applications, regardless of sample type. •Flexible and adaptable chemistry allows for use in multiple applications. We believe our proprietary chemistry provides the ability to measurea variety of molecular targets in many necessary applications, including RNA expression levels, expressed RNA gene rearrangements (such asgene fusions and insertions), and DNA point mutations, and offers the ability to quantify these applications on a variety of NGS platforms. Thisflexibility provides customers the ability to optimize their use of our technologies based on their specific throughput, workflow andapplication needs. Our proprietary chemistry is comparatively simple, with fewer steps than competing technologies. For example, compared toRT-quantitative PCR (“qPCR”) our chemistry does not require extraction or cDNA synthesis. Compared to traditional RNA sequencing, ourchemistry does not require extraction, cDNA synthesis, shearing, rRNA depletion, ligation, adenylation, or size selection. We believe that theelimination of these steps helps prevent biases associated with these steps, sample degradation and increased opportunities for technician error. •Robust data. Molecular profiling produces large amounts of information that is used, among other things, to make important decisions, such asidentifying potential drug targets or selecting a patient for a therapeutic treatment. This information is valuable only to the extent it accuratelyrepresents the true biology of the test sample and the same answer can be produced under many different conditions. Our chemistries are highlyspecific and sensitive, meaning they can detect the right target even when very little is present in the sample. Our system produces consistentresults on a replicate-to-replicate, day-to-day and instrument-to-instrument basis. •Automation provides superior workflow and ease of use. Our technologies are designed with fewer workflow steps in part due to theelimination of the need for complex sample-preparation processes such as extraction, cDNA synthesis, labeling, selection, depletion andshearing. This enables customers to limit hands-on time and the need for specialized skills, resulting in turnaround times of approximately 36hours. Additionally, our HTG EdgeSeq system further integrates sample preparation for targeted sequencing and greatly simplifies the databioinformatics, so customers looking to leverage their NGS instrument can seamlessly add this capability to their current workflows. •Simplified bioinformatics. Our software provides data in a simple and easy to use format through a simple graphical user interface (“GUI”) thatis flexible enough for researchers yet structured enough for clinical laboratories. The HTG EdgeSeq parser software, which processes the datafrom the NGS platform, is modular so that new applications can be downloaded without any changes to hardware. We believe the simplicity ofour bioinformatics solution will help drive the adoption of our platform.7Our TechnologyHTG EdgeSeq ChemistryOur HTG EdgeSeq chemistry is shown schematically in the following figure. Specifically, DNA nuclease protection probes, or DNA protection probes,which include a target-specific region flanked by universal wing sequences are hybridized to targeted RNAs. Target RNA can be both soluble and cross-linked in the biological matrix. Universal DNA wingmen probes are hybridized to the wings to prevent S1 nuclease digestion. S1 nuclease is added to removesingle-stranded nucleic acids, including unhybridized DNA protection probes and RNA. Following S1 nuclease treatment, the only remaining DNAprotection probes in the reaction are those hybridized to targeted RNA and wingmen probes to form a hybridized complex. This produces an approximately1:1 ratio of DNA protection probes to the RNA targeted in the sample. Alkaline hydrolysis of the hybridized complexes releases the DNA protection probesfrom such complexes. The released DNA protection probes are ready for quantitation. DNA protection probes are labeled with sequencing adaptors and tagsin a thermocycler. The labeled DNA protection probes are concentrated, pooled, and ready for sequencing using standard NGS protocols. Data from the NGSinstrument is processed and reported by the parser software provided with the HTG EdgeSeq system. Key Advantages of our HTG EdgeSeq Chemistry •Multiplexing tens, hundreds or thousands of targets. Measuring multiple genes in a single reaction can be challenging with competitivetechnologies due to the complex interactions of reaction components. While we are currently marketing a panel with our HTG EdgeSeqchemistry that can profile up to 2,560 genes in a sample, we believe we can develop applications using our chemistry for multiplexing morethan 2,560 genes if there is a customer need. The high level of gene multiplexing allows for significantly lower amounts of tissue to be used persample than in competitive low-plex profiling technologies. •No RNA extraction. Competitive technologies for assessing RNA generally require RNA that is isolated and purified from other componentsfound in the sample. These time-consuming steps may lead to some target loss and bias the test outcome. In FFPE tissues, for example, it hasbeen reported that a fraction of the RNA is lost in the purification process because it cannot be separated from insoluble tissue components andthe fixation and embedding process or long storage times for FFPE tissue may damage the RNA and break it into smaller, more difficult toanalyze fragments. This makes molecular profiling of small FFPE tissues particularly challenging and can result in testing failures and loss ofprecious samples due to insufficient RNA recovery. These biases introduced by RNA extraction cannot be overcome and may be magnifiedthroughout the subsequent analysis. Our proprietary chemistry does not require RNA extraction for FFPE samples or most other sample types(we recommend extracting RNA from fresh-frozen tissue samples to prevent processing variability), improves utilization of precious samples,improving workflow and reducing costs by eliminating a step known to bias the data.8 •No cDNA synthesis. Many competitive technologies, most prominently qRT-PCR and traditional RNA sequencing, require conversion of RNAinto DNA for analysis. This process, called reverse transcription, requires an enzyme to move along the extracted RNA to create a DNA copy ofthe molecule. When damaged and fragmented RNA is used, these small RNA strands become increasingly difficult to convert into DNA in anaccurate and reproducible manner. Our proprietary chemistry does not require conversion of the RNA to DNA by reverse transcription,removing a technical difficulty experienced with competitive technologies. •Short protection probes. Many samples contain RNA degraded by various combinations of heat, age, poor processing, and fixation. In thesesamples, the RNA is damaged and fragmented into smaller strands. Utilizing short protection probes of 50 bases or less, we believe ourproprietary chemistry is more efficient than competitive technologies that require longer strands of RNA for quantitation. •Simplicity. Our proprietary chemistry is simple, with fewer steps than competing technologies. Compared to RT-qPCR, our chemistry does notrequire extraction or cDNA synthesis. Compared to traditional RNA sequencing, our chemistry does not require extraction, cDNA synthesis,shearing, rRNA depletion, ligation, adenylation, or size selection. We believe that the accumulation of these steps required by othertechnologies results in amplification of biases, sample degradation and increased opportunities for technician error.HTG Instrument PlatformOur assays and instruments were developed and are manufactured under ISO 13485:2003 guidelines using our proprietary HTG EdgeSeq chemistry tosimplify multiplexed nucleic acid testing in research and clinical laboratories. The entire workflow from sample preparation to a molecular profiling reportcan be accomplished in approximately 36 hours for 96 samples. With the speed, flexibility, sensitivity, and accuracy of our HTG platforms, combined withthe system’s ability to work effectively with small sample volumes, researchers can profile tens, hundreds or thousands of different genes per sample. The HTG EdgeSeq platform (shown above) consists of a processor, a host computer and integrated software. The processor is a fully automatedinstrument that prepares biological samples for quantitation using proprietary, electronically barcoded, single-use consumables. The processor has barcodescanner units to process the two-dimensional barcodes printed on the consumables loaded into the instrument. The barcoded consumables are single-use inorder to reduce operator errors and provide chain of custody traceability for the samples. The robotic systems within the instrument are engineered for reliableperformance and low maintenance. The walking path of the robot is programmed to minimize any chance of contamination of the reagents or samples. Onehost computer supports up to six processors allowing laboratories to easily expand their capacity by adding processors.Applications of our HTG EdgeSeq technology combine the HTG EdgeSeq processor with a NGS platform to enable the quantitative analysis of tens,hundreds or thousands of targeted RNAs in a single panel. The sample is prepared for quantitation on the processor, then labeled with molecular sequencingadaptors and tags. The labeled samples are concentrated, pooled, and sequenced on a NGS platform using standard protocols. Data from the NGS instrumentare processed and reported by the parser software included with the system. HTG EdgeSeq assays currently are available to process sample batches rangingfrom eight to 96.In addition to direct sales of our systems, we utilize several alternative arrangements to sell our systems. Our platform can be purchased directly by ourcustomers, who also then purchase HTG EdgeSeq assays and other consumables from us on an as-needed basis. In some instances, we provide our instrumentsfree of charge on a limited basis to facilitate customer evaluation. We also may choose to install instruments for our customers at no cost, in exchange for anagreement to purchase assays and other consumables from us at a stated price over the term of the agreement, or allow customers to rent our instrument for amonthly fee. As of9December 31, 2017, we had an installed base of 44 instruments (consisting of 31 systems sold, two covered under reagent rental agreements, six evaluationunits and five systems with key opinion leaders) and an additional three instruments installed at third party sites in support of companion diagnosticcollaboration projects.Current Commercial Panels Offered on the HTG EdgeSeq PlatformWe currently market proprietary molecular profiling panels targeting late stage drug development programs with potential breakthrough therapies,such as immuno-oncology. We market these panels to biopharmaceutical companies, with which we collaborate in biomarker development programs. Webelieve these programs could facilitate our commercialization of companion diagnostic tests. In addition, our panels are used in pre-clinical and clinicalresearch areas, which, we also believe, will facilitate our commercialization of diagnostic tests, including tumor classifiers and prognostic tests. Our currentlymarketed panels are: •HTG EdgeSeq Oncology Biomarker Panel. This RNA expression panel measures the expression of up to 2,560 genes implicated in cancer forprofiling tumor tissues, analyzing cancer pathways and identifying new biomarkers across both solid tumors and hematolymphoid neoplasms.We worked with key opinion leaders to identify the genes in this panel, which we believe is a comprehensive list of genes targeting knownsignaling pathways and receptor gene families implicated in cancer. Representative genes in this panel include EGFR, HER2, HER3, HER4,PD-1 and FGFR. When paired with our HTG EdgeSeq miRNA Whole-Transcriptome Assay (below), we provide customers with acomprehensive solution for profiling their large sample archives for novel expression signatures. •HTG EdgeSeq Immuno-Oncology Assay. One of the most promising areas of cancer therapy is immunotherapy or immuno-oncology, where newclasses of oncology drugs are thought to enable or boost the host immune response towards tumors. Multiple drugs targeting the genes CTLA4,PD-1 and PD-L1 are on market with additional candidates moving into late-stage trials. Profiling samples for the genes targeted by thesetherapies may be predictive of drug response and aid in the stratification of patients into responsive and non-responsive groups. The HTGEdgeSeq Immuno-Oncology Assay measures the expression of 549 of these immuno-oncology-associated genes. •HTG EdgeSeq DLBCL Cell of Origin Assay. DLBCL tumors are frequently classified into either the activated B-cell like (“ABC”) or germinalcenter B-cell like (“GCB”) sub-types by measuring the molecular profile of the tumor. These two subtypes display different clinicalpathologies, as patients with the GCB subtype of DLBCL tend to respond differently than those of the ABC sub-type. With many of the largenumber of new DLBCL-targeting drugs appearing to have greater efficacy in one of the sub-types, a need for a reliable, FFPE-based cell oforigin classification assay has emerged. The HTG EdgeSeq DLBCL Cell of Origin Assay is being utilized in numerous late-stage drug programsto stratify these patients. •HTG EdgeSeq PATH Assay. The HTG EdgeSeq PATH Assay has been designed for retrospective gene expression profiling (“GEP”) tocompliment traditional immunohistochemistry (“IHC”) testing by allowing investigators to assess mRNA expression of 470 targets when tissueavailability is limited. The assay enables a wide variety of applications, including pre-screening of samples to guide subsequent testing anddevelopment of novel gene signatures. •HTG EdgeSeq miRNA Whole-Transcriptome Assay. Human microRNAs are short non-coding strands of RNA that are believed to be used by thecell for gene regulation. The HTG EdgeSeq miRNA Whole-Transcriptome Assay enables the simultaneous profiling of 2,083 microRNAs,allowing new, potentially clinically relevant miRNA profiles to be discovered. Our ability to efficiently profile small FFPE samples is asignificant differentiator in the rapidly growing microRNA market. •HTG EdgeSeq DLBCL Cell of Origin Assay EU. The HTG EdgeSeq DLBCL Cell of Origin Assay EU is an in vitro diagnostic (“IVD”) assay thatuses GEP to determine the cell of origin (“COO”) subtype of DLBCL tumors from FFPE tissue section. The gene expression data are assessed bya classification algorithm and the tumor samples are determined to be of the ABC, GCB or unclassified subtype. This product has obtained CE-marking in Europe where it is available for diagnostic use. It is not for sale in North America. •HTG EdgeSeq ALKPlus Assay EU. The HTG EdgeSeq ALKPlus Assay EU is an IVD NGS-based assay sold in the EU intended to measure andanalyze mRNA ALK gene fusion events in FFPE lung tumor specimens from patients previously diagnosed with NSCLC. This product has alsoobtained CE-marking in Europe where it is available for diagnostic use. It is not for sale in North America. •HTG EdgeSeq EGFR, KRAS and BRAF Mutation Assay (VERI/O lab service offering exclusively). TheHTG EdgeSeq EGFR, KRAS, and BRAF Mutation Assay is an RUO assay currently available exclusively as a VERI/O laboratory service anddetects 23 mutations in EGFR, KRAS and BRAF from a 5 µm section of FFPE tissue. Retrospective analysis of the tumor’s mutational statusmay help researchers understand the tumor response to targeted therapy. This assay is extraction-free and can be used with small samples suchas a needle core biopsy.10Opportunities for Comprehensive Molecular Profiling in DiagnosticsWe are planning to develop a portfolio of molecular diagnostic products using our proprietary technology to provide a single, efficient testing systemfor sample profiling that integrates seamlessly into a customer’s NGS testing workflow.We are initially focused on areas where the diagnostic testing paradigm has significant inefficiencies. For example, many leading medical institutionsare shifting from a single-drug / single-test approach to a broader tumor profiling strategy for their oncology practices. Rather than testing for singlemutational analyses, such as KRAS mutations in colorectal cancer, these institutions use their NGS platforms to assess the mutational status of 50 or moregenes. In addition, the information a physician needs to make clinical decisions often comes from tests conducted using various testing modalities such asIHC, FISH and NGS. These complexities lead to a growing and unmet demand in clinical diagnostics for more comprehensive molecular profiles that caninclude RNA expression, RNA fusions and rearrangements, DNA mutations and protein expression.We are developing solutions to address the detection and measurement of gene rearrangements such as gene fusions and insertions. A fusion gene is ahybrid gene formed from two previously separate genes. A well-established example is the EML4-ALK fusion gene found in a subset of malignant lungcancers. Our research team previously demonstrated feasibility to simultaneously detect and measure key gene fusions in lung cancer such as ALK, ROS1,RET and NTRK1 from multiple small sample types including FFPE, cell lines and purified RNA. An insertion is the addition of one or more nucleotides intoa genomic sequence; a small percentage of NSCLC exhibit HER2 exon 20 insertions.We are currently developing our HTG EdgeSeq ALKPlus Assay (“ALKPlus Assay”) as our first clinical diagnostic test for the U.S. market. This testpanel is in clinical study phase and three of the four PMA modules have been submitted to the FDA. We completed the CE marking of theHTG EdgeSeq ALKPlus Assay EU in Europe in March 2017, and currently expect to obtain FDA pre-market approval for the ALKPlus Assay in mid-2018though prioritization of other diagnostic programs for customers may cause this expected timeline to be adjusted. The intended use for the ALKPlus Assay, ifapproved by the FDA, will be as a companion diagnostic for crizotinib therapy for ALK positive NSCLC cases. Information on the ROS1, RET, NTRK1 andHER2 gene rearrangements included in the ALKPlus Assay panel will be provided with RUO status. After obtaining the appropriate exemption(s), we believethe ROS1, RET, NTRK1 and HER2 gene rearrangements detected with the ALKPlus Assay could also be used for investigational use only (“IUO”) for certainlate-stage drug development trials, and, as appropriate, receive FDA approval in the future.Ultimately, we believe that HTG technology can bring multiparameter testing to a wide variety of solid tumor sample types. We will need to develop,refine and implement new panel protocols and make changes or adjustments to our chemistry and software to optimize these planned applications and panelsfor use with our HTG EdgeSeq system. This will require substantial effort from our research scientists and the use of various laboratory equipment, suppliesand materials, which combined represent the most significant costs that we expect to incur in connection with the development of these applications andprofiling panels.We are leveraging our platform to develop comprehensive molecular profiling panels across an increasing set of molecular applications, with initialfocus in immuno-oncology and next generation pathology. In conjunction with our biopharmaceutical collaborators, we plan to develop novel RNA-basedgene panels and possibly classifiers that can provide information about inflammation signatures and the molecular classification of tumors. Separately, wealso plan to develop novel RNA-based gene panels designed for expanded applications in immune health monitoring and prescreening, detection of hyper-progression and predicting patient response to combination therapies. We believe that we will need to develop, refine and implement new panel protocolsand make changes or adjustments to our chemistry and software to optimize these planned applications and panels for use with our HTG EdgeSeq system. Weexpect this to require substantial effort from our research scientists and the use of various laboratory equipment, supplies and materials, which togetherrepresent the most significant costs that we expect to incur in connection with the development of these applications and profiling panels.Serving the decentralized markets with Project JANUSIn addition to continued menu expansion for clinical diagnostic products we have begun the development of our next generation instrument targetingthe lower throughput clinical market. We refer to this development program as Project JANUS. We believe the lower throughput clinical market willpotentially increase our addressable market for instrument sales from hundreds to thousands of labs. The molecular testing market is served by a mix ofcentralized reference laboratories, comprehensive cancer centers, and decentralized regional hospital laboratories. Volumes of particular case types anddownstream testing needs for solid tumors are somewhat unpredictable for these providers. We believe Project JANUS is well suited for managing low,medium, and surge testing volumes; thus, assisting our customers with this unpredictable aspect of their businesses. We anticipate testing panels for ProjectJANUS to include mutations, fusions, expression classifiers and a molecular surrogate for IHC. Our approach is to serve centralized markets with the HTGEdgeSeq system and expand to the decentralized market with Project JANUS. We believe our current HTG EdgeSeq system has the throughput capabilitiesthat match the needs of the centralized market. Project JANUS is our planned approach to expand our addressable market to the lower sample throughput labsand further decentralize the market. Due to various research and development priorities, Project JANUS development efforts were put on hold during the thirdquarter of 2016. We intend to resume development efforts in accordance with development prioritization.11Research and DevelopmentWe have committed, and expect to commit, significant resources to developing new technologies and products, improving product performance andreliability and reducing costs. We have assembled an experienced research and development team with the scientific, engineering, software and process talentthat we believe is required to successfully grow our business.

We believe these programs have the potential to generate future revenue through the sale of HTGEdgeSeq instruments and test kit annuities associated with a successfully approved clinical diagnostic as the related drug gains adoption. Our research effortsare currently focused on the expansion of our technology into new immune-oncology applications as well as other applications in solid and liquid biopsies,while working to continuously improve assay performance and probe design.Sales and MarketingWe distribute our instruments and consumables via direct sales in the United States and Europe and also through distributors in parts of Europe andother countries. As of December 31, 2017, our U.S. sales and marketing organization consisted of 23 employees including 12 in direct sales or salesmanagement, five in sales support and six in marketing. In addition to our direct sales team in the United States, as of December 31, 2017, we had five directsales and support employees in Europe and distribution agreements in several additional countries. This sales model provides us with direct sales coverage inthe United Kingdom, France, Germany, Switzerland, Belgium and the Nordic countries, with distributors in Spain, Portugal, Italy and Israel.Our sales and marketing efforts target biopharmaceutical companies, clinical research centers and clinical diagnostic labs focused on sample profilingfor translational research, biomarker/companion assay development and lab-developed diagnostic testing. We intend to promote adoption of our HTGEdgeSeq system, sample profiling panels and future molecular diagnostic assays upon marketing clearance or approval by the FDA, by expanding our U.S.sales force, building a greater direct sales presence in Europe, expanding international distribution and continuing to collaborate with key opinion leaders tovalidate our platform and to influence utilization of our products.Our top two customers accounted for 54% and 8% of our revenue for the year ended December 31, 2017, compared with 29% and 12% for the yearended December 31, 2016. QML was our largest customer for the year ended December 31, 2017 with approximately $7.9 million of collaborativedevelopment services revenue recognized for work performed for two precision diagnostic programs under our Governing Agreement.Manufacturing and SuppliersWe primarily perform manufacturing and final acceptance testing in house. External resources are leveraged for their specific expertise in eitherproducing components for our HTG EdgeSeq instrument and raw materials for our consumables in accordance with our designs, or based on their catalogproducts which are utilized as is within our designs.

Growth Term Loan A bearsinterest at a fixed rate of 8.50% per annum. On or prior to June 30, 2015, the Loan Agreement allowed us to borrow one additional term loan (“Growth TermLoan B”) for up to $5.0 million, subject to the satisfaction of certain borrowing conditions. We received Growth Term Loan A proceeds, net of a $320,000original issue discount, with a requirement to pay a final payment of 3.75% of the total amount borrowed.In August 2015, the Company and its lenders amended the Growth Term Loan to extend the availability of Growth Term Loan B until March 31,2016. Pursuant to such amendment, we made monthly interest-only payments until April 1, 2016. Following the interest-only payment period, equal monthlypayments consisting of principal and interest amortized over the remaining term of the loan through the September 1, 2018 maturity date are due. Theamendment also increased the final fee payment percentage to 4.75%. In February 2016, the Company notified its lenders, pursuant to the requirements of theamendment to the Growth Term Loan, of its intention to draw the remaining $5.0 million available under Growth Term Loan B. This additional principal willbe repaid evenly over the course of 30 months beginning April 1, 2016 and bears interest at a fixed rate of 8.75%. The final fee premium relating to GrowthTerm Loan B of $237,500 is being amortized to interest expense, using the effective interest method, over the term of Growth Term Loan B.We may prepay all, but not less than all, of the loaned amount plus accrued and unpaid interest thereon through the prepayment date with 15 days’notice to Oxford. In accordance with the August 2015 amendment, we will be obligated to pay a prepayment fee equal to 1% of the principal amount repaid ifthe loan is repaid prior to the September 1, 2018 maturity date. We are not entitled to reborrow any amounts of principal once such principal has been repaid.The agreement was again amended in June 2016 to modify the definitions of permitted indebtedness and permitted liens to provide for an increasedmaximum amount of permitted indebtedness, authorize a new category of permitted indebtedness and authorize a new category of permitted liens.While any amounts are outstanding under the credit facility, we are subject to several affirmative and restrictive covenants, including covenantsregarding delivery of financial statements, maintenance of inventory, payment of taxes, maintenance of insurance, dispositions of property, businesscombinations or acquisitions, incurrence of additional indebtedness and transactions with affiliates, among other customary covenants. We are also restrictedfrom paying cash dividends or making other distributions or payments on our capital stock except for repurchases of stock pursuant to employee stockpurchase plans, employee restricted stock agreements, stockholder rights plans, director or consultant stock option plans, or similar plans, provided suchrepurchases do not exceed $100,000 in the aggregate per fiscal year.We granted the Agent a security interest in our personal property to secure our obligations under the Growth Term Loan. The security interest does notextend to patents, trademarks and other intellectual property rights (except for rights to payment related to the sale, licensing or disposition of suchintellectual property rights) or certain other specified property. If we default under our Growth Term Loan, our lenders could foreclose on our assets,including substantially all of our cash, which is held in accounts with our lenders.Upon the occurrence of certain events, including but not limited to the failure by us to satisfy our payment obligations under the loan agreement, thebreach of certain of our other covenants under the loan agreement, and the occurrence of a material adverse change, the Agent will have the right, amongother remedies, to declare all principal and interest immediately due and payable, and will have the right to receive the final payment fee and, if the paymentof principal and interest is due prior to maturity, a prepayment fee. The Agent also will have the right, among other remedies, to foreclose upon and/or sell orotherwise liquidate our personal property upon the occurrence of certain events.Warrants granted to each of the Lenders in connection with Growth Term Loan A are exercisable until August 22, 2024 and were automaticallyconverted to warrants for common stock upon completion of our initial public offering in May 2015. In connection with the funding of Growth Term Loan B,in March 2016, we issued Oxford an additional common stock warrant exercisable for 45,307 shares of common stock at an exercise price of $2.759 per share,and the warrant previously issued to SVB automatically became exercisable for an additional 5,317 shares of common stock at an exercise price of $23.51 pershare in accordance with the Growth Term Loan.15Development and Component Supply Agreement with Illumina, Inc.In June 2017, we entered into an Amended and Restated Development and Component Supply Agreement with Illumina, Inc. (“Illumina”), effectiveMay 31, 2017 (the “Restated Agreement”), which amended and restated our IVD Test Development and Component Supply Agreement originally enteredinto with Illumina in October 2014 (the “Original Agreement”). The Restated Agreement provides for the development and worldwide commercialization bythe Company of nuclease-protection-based RNA or DNA profiling tests (“IVD test kits”) for use with Illumina’s MiSeqDx sequencer in the field of diagnosticoncology testing in humans (the “Field”).Under the Restated Agreement, the parties have agreed to continue activities under the first development plan which was entered into pursuant to theOriginal Agreement relating to our HTG EdgeSeq ALKPlus Assay. In addition, we may, at our discretion, submit additional development plans for IVD testkits in the Field to Illumina for its approval, not to be unreasonably withheld.Under each development plan, Illumina will provide specified regulatory support and rights, and develop and deliver to us an executable version ofcustom software, which, when deployed on Illumina’s MiSeqDx sequencer, would enable sequencing by the end-user of the subject IVD test kit probe library.Illumina retains ownership of the custom software, subject to our right to use the custom software in connection with the commercialization of IVD test kits.In addition to fees paid in 2015 under the Original Agreement, we are required to pay Illumina up to $0.6 million in the aggregate upon achievement ofspecified regulatory milestones relating to the IVD test kits, though none of these regulatory milestones have been reached through December 31, 2017. Wehave also agreed to pay Illumina a single digit percentage royalty on net sales of any IVD test kits that we commercialize pursuant to the Restated Agreement.We submitted two additional development plans for IVD test kits to Illumina in the second and fourth quarters of 2017. Following receipt of thecustom software module for the first of these test kits, we paid Illumina $50,000, which is included in our statements of operations for the year endedDecember 31, 2017. No payments were made to Illumina during the year ended December 31, 2016 under this agreement. Ongoing research and developmentcosts for development plans under the Restated Agreement have been expensed as incurred.Absent earlier termination, the Restated Agreement will expire in May 2027; however, Illumina is no longer obligated to notify us of changes in itsproducts that may affect our IVD test kits after May 31, 2023. We may terminate the Restated Agreement at any time upon 90 days’ written notice and mayterminate any development plan under the Restated Agreement upon 30 days’ prior written notice. Illumina may terminate the Restated Agreement upon 30days’ prior written notice if we undergo certain changes of control, subject to a transition period of up to 12 months for then-ongoing development plans.Either party may terminate the Restated Agreement upon the other party’s material breach of the Restated Agreement that remains uncured for 30 days, orupon the other party’s bankruptcy.Authorization, Supply and Regulatory Authorization Agreement with Life Technologies CorporationIn March 2016, we entered an Authorization, Supply and Regulation Authorization Agreement with Life Technologies Corporation (“LTC”) a whollyowned subsidiary of Thermo Fisher Scientific, Inc., for the development and worldwide commercialization by us of up to five RNA-based NGS panels (“HTGAssays”) for use with LTC’s sequencing instruments and components supplied to end‑users by LTC.Pursuant to the agreement, we have agreed to obtain our requirements for certain components to be used in the development of HTG Assays from LTC.In March 2016, we purchased approximately $250,000 of LTC products and equipment in accordance with this agreement. LTC has agreed to providesupport in our efforts to obtain regulatory approval of the HTG Assays. We are required to pay LTC a milestone payment in the mid-six figure dollar rangeupon certain regulatory achievements for each HTG Assay. In addition, we have agreed to pay LTC a single digit percentage royalty on net sales of HTGAssays that we commercialize pursuant to the agreement. No milestone or royalty payments have been accrued or made pursuant to this agreement as ofDecember 31, 2017.Absent early termination, the initial term of the agreement will expire in March 2021 and thereafter will automatically renew for additional two yearperiods for as long as we continue to develop or sell HTG Assays, provided that neither party provides written notice of its election to terminate theagreement at least 60 days prior to expiration of the then-current term. Either party may terminate the agreement (a) upon the other party’s material breachthat remains uncured for 30 days, (b) upon the other party’s bankruptcy or (c) upon written notice in the event the party providing notice reasonablydetermines that continued performance under the agreement may violate any regulatory law, or any other applicable law or regulation or FDA guidance.Bristol-Myers Squibb Company AgreementIn May 2016, we entered into a Collaboration Agreement with BMS for the development of custom RUO assays for BMS based on our HTG EdgeSeqtechnology. Following development of each custom RUO assay, at BMS’s request, we may also perform sample processing services using such custom RUOassay(s) and/or supply the custom RUO assay(s) to BMS or its third-party subcontractors.16Additional development related to immuno-oncology research may be undertaken pursuant to the Collaboration Agreement in accordance with a mutuallyacceptable work plan, which is incorporated by written amendment.BMS paid an initial non-refundable, non-creditable program set-up fee, and has agreed to pay an annual non-refundable, non-creditable projectmanagement fee in quarterly installments, as well as a fee for each assay developed. Each such fee was or is in the low six-figure range. At BMS’s request, wewill supply custom RUO assay kits and perform sample processing services.The agreement will expire on May 11, 2019 or, if a project is then ongoing, the date of delivery of the final report for such project. Either party mayterminate the agreement upon the other party’s material breach or default in the performance of a material obligation under the agreement or if certainwarranties or representations are untrue in any material respect, either a default, and such default remains uncured for 60 days or such longer period if thedefault cannot be cured within 60 days. BMS may terminate a project upon 90 days’ prior written notice.Merck KGaA AgreementsMaster CDx AgreementIn October 2016, we entered a Master CDx Agreement with Merck KGaA to serve as the basis for one or more project agreements to develop, seekregulatory approval for, and commercialize companion diagnostic assays for Merck KGaA drug candidates and corresponding therapeutics. Concurrently, weentered into a first project agreement under the agreement concerning our sequencing-based DLBCL cell of origin assay (“DLBCL Assay”) and MerckKGaA’s investigational drug, M7583 (the “Project”).The Project has three stages aligned with timelines and outcomes of M7583 development. The timing of our development activities and paymentsmay be affected by the M7583 development timing and activities which is controlled by Merck KGaA. During stages 1 and 2, we have agreed to performspecified DLBCL Assay development activities. In stage 3, we have agreed to seek to obtain applicable regulatory approvals on the DLBCL Assay and makeit commercially available in the United States and certain other jurisdictions.Stages 2 and 3 each have an up-front payment, and all stages of the Project have milestone-based payments. We are eligible to receive up to a total of$9,900,000 over a period of approximately nine years in fixed or determinable contract consideration comprising up-front and milestone payments. Inaddition, during stages 1 and 2 of the Project, we will sell DLBCL Assay kits and/or perform sample processing services upon request of, and as instructed by,Merck KGaA.Merck KGaA may terminate the Project or any other project agreement by providing three months’ prior written notice, at which point Merck KGaAwill be required to reimburse us for certain costs incurred during the termination period, and we will be required to reimburse Merck KGaA for any costs thathave been prepaid without being incurred prior to termination. Further, either party may also terminate the agreement or a project agreement upon the otherparty’s material breach that remains uncured for 60 or 45 days, respectively, or upon the other party’s bankruptcy.Master Collaboration AgreementIn December 2017, we entered into a Master Collaboration Agreement for translational research programs with Merck KGaA. The MasterCollaboration Agreement complements the Master CDx Agreement with Merck KGaA and includes a statement of work with EMD Serono, the U.S.biopharmaceutical affiliate of Merck KGaA.Under the first statement of work, we plan to develop and manufacture a custom profiling assay to support biomarker research for six indicationswithin Merck KGaA’s drug development pipeline. The assay is expected to be kitted for use on HTG EdgeSeq instruments acquired by Merck KGaA and/ortheir contract research organization partners.QIAGEN AgreementsGoverning AgreementIn November 2016, we entered the Governing Agreement with QML. The Governing Agreement creates a framework for the companies to combinetheir technological and commercial strengths to offer biopharmaceutical companies a complete NGS-based solution for the development, manufacture andcommercialization of companion diagnostic assays. Under the Governing Agreement, the parties jointly seek companion diagnostic programs withbiopharmaceutical companies, QML enters into sponsor project agreements with interested biopharmaceutical companies for specified projects, and we andQML enter into statements of work, that set forth the rights and obligations of each party with respect to each project.17The parties’ relationship under the Governing Agreement is exclusive in the oncology field. Such exclusivity in the oncology field may be lost andbecome non-exclusive if certain performance targets are not met. Projects may be undertaken in non-oncology fields at each party’s discretion on a non-exclusive basis.We and QML share net profits under each statement of work, at a percentage that primarily depends on which company’s intellectual property formsthe basis for the particular assay under the applicable statement of work. Each statement of work provides additional financial terms for the correspondingproject, which terms depend on the respective development and/or commercialization activities of the parties.The Governing Agreement has a five-year term. However, either party may terminate the Governing Agreement upon (i) the other party’s uncuredmaterial breach, bankruptcy or insolvency, (ii) specified events affecting all statements of work, or (iii) a change of control by either party, except neitherparty will have such change of control termination right to the extent the Governing Agreement relates to SOW One, SOW Two or SOW Three (each definedbelow). In the event a party terminates the Governing Agreement for its own change of control, a $2.0 million termination payment will be payable to thenon-terminating party.Stock Purchase AgreementPursuant to a stock purchase agreement, entered concurrent with the Governing Agreement, QIAGEN North American Holdings, Inc. (“QNAH”)another wholly owned subsidiary of QIAGEN N.V., purchased 833,333 shares of our common stock on November 17, 2016 at $2.40 per share, for a totalpurchase price of $2.0 million. The purchase price for the shares of common stock purchased by QNAH on November 17, 2016 reflected the parties’agreement as to the fair market value of the shares as of the closing. However, the portion of the purchase price per share that exceeded the most recentlyreported closing price of our common stock, or $175,000 in the aggregate, was attributed to the Governing Agreement and recorded as deferred revenue to berecognized on a straight-line basis over the Governing Agreement’s five-year term. No additional shares of our common stock were purchased by QNAH inthe second tranche closing allowed for in this agreement and QNAH had no further obligation to purchase our common stock under the stock purchaseagreement as of December 31, 2017.Statement of Work No. OneIn June 2017, we entered into the first statement of work (“SOW One”) under the Governing Agreement with QML. SOW One addresses the initialactivities to be performed by us and QML in support of the development and potential commercialization of a NGS-based companion diagnostic assay that isthe subject of a sponsor project agreement between QML and a biopharmaceutical company (“Pharma One”). The parties expect development activities forthe assay to be the subject of more than one work plan under the sponsor project agreement and a corresponding number of statements of work under theGoverning Agreement.QML pays us a monthly fee for development work performed by us and our subcontractors. We also will share any net profits resulting fromperformance of the development work as determined pursuant to the Governing Agreement. Such profit sharing payment(s) is deemed to be fixed ordeterminable upon completion of SOW One deliverables, acceptance of corresponding deliverables by Pharma One, and the mutual agreement by QML andus on the calculation of net profit.SOW One will expire when all activities and deliverables have been completed by the respective responsible party and all payments from QML to ushave been delivered, including any required profit sharing, unless terminated earlier in accordance with the terms of the Governing Agreement.Contemporaneous with entry into SOW One, the Governing Agreement was amended to provide that neither party may terminate SOW One or theGoverning Agreement to the extent it relates to SOW One in the event of a change of control.Statement of Work No. TwoIn October 2017, we entered into SOW Two under the Governing Agreement with QML. SOW Two was made effective as of June 2, 2017 (“OnsetDate”). SOW Two addresses development activities conducted by us and QML since the Onset Date and those expected to be further conducted by parties inconnection with a sponsor project agreement between QML and BMS (the “BMS/QML SPA”).The development work performed and expected to be performed by us and QML under SOW Two (“Initial Phase Work”) is expected to form the basisof a multi-stage project leading to the potential development and commercialization of a companion diagnostic assay in support of one or more of BMS’stherapeutic development and commercialization programs. SOW Two will expire upon completion of the Initial Phase Work and receipt by us of all amountsdue for such work, which we believe will occur in mid-2018 barring any unexpected project delays. QML will pay us mid-single digit millions of dollars forthe Initial Phase Work18performed by us under SOW Two. In addition, we will share in any net profits (as determined under the Governing Agreement) generated by the Initial PhaseWork with QML on an approximately quarterly basis throughout the term of SOW Two.SOW Two also provides that, notwithstanding anything in the Governing Agreement to the contrary, neither party shall have the right to terminateSOW Two or the Governing Agreement to the extent it relates to SOW Two upon a change of control of either party.Concurrently with SOW Two, as acondition to BMS’s approval of SOW Two, we entered into a Supplement Agreement with QML and BMS, made effective as of the Onset Date. TheSupplement Agreement establishes certain rights and obligations of the parties with regard to confidential information and other intellectual property neededto perform, and/or produced as a result of, the Initial Phase Work. We will receive sole ownership of certain improvements (as specified in the SupplementAgreement) that may be produced as a result of the Initial Phase Work, and have agreed to grant certain royalty-free, non-exclusive license rights to ourtechnology in the event of a project delay caused by us and to certain patent rights we may obtain as a result of the Initial Phase Work. In addition, we willhave joint ownership of certain other results of the Initial Phase Work, and royalty-free, non-exclusive license rights to BMS- or QML-owned (solely orjointly) patents resulting from the Initial Phase Work. The Supplement Agreement will expire or terminate upon expiration or termination of the BMS/QMLSPA, which is expected to be approximately coextensive with the term of SOW Two.Statement of Work No. ThreeIn January 2018, we entered into SOW Three under the Governing Agreement with QML. SOW Three relates to development activities for a NGS-based clinical-trial assay (“SOW Three Project”) in connection with a sponsor project agreement between QML and a pharmaceutical company (“PharmaThree”). If successfully completed, SOW Three Project is expected to lead to subsequent assay development activities and the potential commercialization ofa companion diagnostic assay for a corresponding Pharma Three drug.QML has agreed to pay us low, single-digit millions of dollars in development fees for the SOW Three Project, which is expected to be completed inthe second quarter of 2018. In addition, we and QML will share any net profits (as determined under the Governing Agreement) generated by the SOW ThreeProject on an approximately quarterly basis over the term of SOW Three.Under the terms of SOW Three, we have agreed to assign our rights in certain SOW Three Project‑related intellectual property (“Project IP”)predominantly related to Pharma Three’s drug candidate(s) to QML for ultimate assignment to Pharma Three in accordance with the project agreement.Improvements to the respective background intellectual property of the parties generally will be owned solely by the respective party. Otherwise, Project IPwill be jointly owned among us, QML and Pharma Three.Pursuant to the terms of SOW Three, if Pharma Three terminates the project agreement or the SOW Three Project due to our uncured material breach ofSOW Three, we will be required to negotiate in good faith with Pharma Three a non‑exclusive, royalty‑bearing license to certain of our intellectual propertyas reasonably necessary for Pharma Three to research, develop, and commercialize an in vitro diagnostic assay meeting the same specifications as inSOW Three.Neither we nor QML have the right to terminate SOW Three or the Governing Agreement to the extent it relates to SOW Three upon a change ofcontrol of either party. In addition, if Pharma Three terminates the project agreement or the SOW Three Project for an uncured material breach that is directlycaused by our or QML, then, for the non‑breaching party, the exclusivity obligation of the Governing Agreement will terminate solely with respect to thedevelopment for Pharma Three and/or its affiliates of an in vitro diagnostic assay meeting the same specifications as in SOW Three.SOW Three expires upon completion of the SOW Three Project and receipt by us of all amounts due for such work.QNAH Convertible Note AgreementIn October 2017, we issued a subordinated convertible promissory note (the “QNAH Convertible Note”) to QNAH in the principal amount of $3.0million against receipt of cash proceeds equal to such principal amount. The QNAH Convertible Note bears simple interest at the rate of 3.0% per annum andmatures on October 26, 2020. Our indebtedness under the QNAH Convertible Note is expressly subordinated in right of payment to the prior repayment infull of our indebtedness under our Growth Term Loan. QNAH may elect to convert all or any portion of the outstanding principal balance of the QNAHConvertible Note and all unpaid accrued interest thereon at any time prior to the maturity date into shares of our common stock at a conversion price of$3.984 per share.Third-Party Coverage and ReimbursementClinical laboratories will acquire our instrumentation through a capital purchase, capital lease or reagent purchasing agreement. These laboratorieswill offer their customers a menu of testing services using our IVD test kits or their LDTs, which they may develop19using components they purchase from us, or a combination of both. Our customers will generate revenue for these testing services by collecting paymentsfrom third-party payors, including public and private payors, as well as patient co-payments.United StatesIn the United States, molecular testing laboratories have multiple options for reimbursement coding, but we expect that the primary codes used will bethe Genomic Sequencing Procedure codes. We are also monitoring the Protecting Access to Medicare Act implementation as well as the recent NationalCoverage Determination for NGS testing by the Centers for Medicare and Medicaid Services (“CMS”).Genomic Sequencing Procedures.The AMA created codes for Genomic Sequencing Procedures (“GSPs”) and other Molecular Multianalyte Assays as part of its calendar year 2015update to the clinical laboratory fee schedule. AMA has since modified the GSP codes to clarify the definition to include DNA and RNA. Our customers mayuse these codes to seek reimbursement for diagnostic multi-analyte test offerings, such as: •Gene expression classifiers for hematolymphoid neoplasms, such as the determination of ABC or GCB subtypes of diffuse large B-celllymphomas; •Gene rearrangements in solid tumors and hematolymphoid neoplasms; •Mutations in solid tumors and hematolymphoid neoplasms.Payments for Tier 1 and Tier 2 Molecular Pathology Procedures and GSPs may be sought from both public and private payors. Claims for Medicarecoverage are processed by private Medicare Administrative Contractors (“MACs”) such as Novitas and Cahaba, and coverage for specific test codes arespecified in Local Coverage Determinations (“LCDs”) issued by individual MACs or National Coverage Determinations (“NCDs”) which apply to all MACs.Private payors issue their own coverage determinations that are largely reflective of the CMS LCDs and NCDs. HTG closely monitors trends in coveragethrough interactions with customers, industry associations such as the College of American Pathologists (“CAP”) and the Association for MolecularPathology (“AMP”) and industry consultants; these trends are key considerations in our product development plans.Our customers may use our products, if approved, and subject to regulatory limitations, to offer testing services that provide an analysis of 5‑50 genesas well as 51 or more genes. In October 2014, CMS released its preliminary determinations regarding the method for determining 2015 payment rates for newcodes under the clinical laboratory fee schedule. CMS recommended that payment rates for GSPs be determined through a process known as gapfill ratherthan by crosswalking to allow CMS and its contractors to gather information about the manner in which the tests are performed and the resources necessary toprovide them, so that ultimately CMS can set an appropriate payment rate for these tests. In the gapfill process, the local MACs determine the appropriate feeschedule amounts in the first year, and CMS calculates a national payment rate based on the median of these local fee schedule amounts in the second year.On September 22, 2017, gapfill pricing for CPTs 81445 and 81450 for the assessment of 5-50 genes in solid and liquid tumors, respectively, were set at $598and $760, respectively, and remains the same as of December 31, 2017. CPT 81455 for the assessment of 51 or more genes in solid and liquid tumors was setat $2,920.We believe that establishment of the aforementioned reimbursement codes specific to genomic sequencing procedures such as our clinical diagnostictests currently in development is an important factor in expanding access to our products. In addition, coverage and reimbursement of our clinical diagnostictests by government and private payors is essential to our commercial success. Accordingly, our strategy includes efforts to encourage third-party payors toestablish coverage, coding and payment that will facilitate access to our tests as we seek FDA approval for these tests and expand our commercializationefforts in the United States. Our success in these efforts depends in part on the extent to which governmental authorities, private health insurers and otherthird-party payors provide coverage for and establish adequate reimbursement levels for tests using our technology. Failure by our customers who use ourtests to obtain coverage and sufficient reimbursement from healthcare payors or adverse changes in government and private third-party payors’ policieswould have a material adverse effect on our business, financial condition, results of operations and future growth prospects.Outside the United StatesOur target markets outside of the United States are Europe and Asia/Pacific. Our diagnostic product menu plans for Europe and Asia/Pacific consistprimarily of NGS‑based test kits that will satisfy existing or emerging testing demand, and we expect to be competing based on testing efficiency, quality andprice.20In Europe, coverage for molecular diagnostic testing is varied. Countries with statutory health insurance (e.g., Germany, France, The Netherlands) tendto be more progressive in technology adoption with favorable reimbursement for molecular diagnostic testing. In countries such as the United Kingdom withtax-based insurance, adoption and reimbursement for molecular diagnostic testing is not uniform and is influenced by local budgets.Failure by our ex-U.S. customers to obtain sufficient coverage and reimbursement for our diagnostic products from healthcare payors or adversechanges in government and private payors’ policies would have a material adverse effect on our ex-U.S. growth prospects and our overall business, financialcondition, and results of operations.Government Regulation – Medical Device RegulationsUnited StatesOur products and operations are subject to extensive and rigorous regulation by the FDA and other federal, state, local and foreign authorities.Currently we are limited to marketing our products in the United States for research use only, which means that we cannot make any diagnostic or clinicalclaims. However, we intend to seek regulatory clearances or approvals in the United States and other jurisdictions to market certain assays for diagnosticpurposes. The clinical diagnostics under development by HTG are classified as “medical devices” under the United States Food, Drug and Cosmetic Act(“FDCA”). The FDA regulates, among other things, the research, development, testing, manufacturing, approval, labeling, storage, recordkeeping,advertising, promotion and marketing, distribution, post approval monitoring and reporting and import and export of medical devices in the United States toassure the safety and effectiveness of such products for their intended use.Unless an exemption applies, each new or significantly modified medical device we seek to commercially distribute in the United States will requireeither a premarket notification to the FDA requesting permission for commercial distribution under Section 510(k) of the FDCA, also referred to as a 510(k)clearance, or approval from the FDA of a PMA application. Both the 510(k) clearance and PMA submission can be expensive, and lengthy, and requirepayment of significant user fees, unless an exemption is available.Device ClassificationUnder the FDCA, medical devices are classified into one of three classes – Class I, Class II or Class III – depending on the degree of risk associatedwith each medical device and the extent of control needed to provide reasonable assurances with respect to safety and effectiveness.Class I devices are those for which safety and effectiveness can be reasonably assured by adherence to a set of regulations, referred to as GeneralControls, which require compliance with the applicable portions of the FDA’s Quality System Regulation (“QSR”) facility registration and product listing,reporting of adverse events and malfunctions, and appropriate, truthful and non-misleading labeling and promotional materials. Some Class I devices, alsocalled Class I reserved devices, also require premarket clearance by the FDA through the 510(k) premarket notification process described below. Most Class Iproducts are exempt from the premarket notification requirements.Class II devices are those that are subject to the General Controls, as well as Special Controls, which can include performance standards, guidelinesand post market surveillance. Most Class II devices are subject to premarket review and clearance by the FDA. Premarket review and clearance by the FDA forClass II devices is accomplished through the 510(k) premarket notification process. Under the 510(k) process, the manufacturer must submit to the FDA apremarket notification, demonstrating that the device is “substantially equivalent,” as defined in the statute, to either: •a device that was legally marketed prior to May 28, 1976, the date upon which the Medical Device Amendments of 1976 were enacted; or •another commercially available, similar device that was cleared through the 510(k) process.To be “substantially equivalent,” the proposed device must have the same intended use as the predicate device, and either have the sametechnological characteristics as the predicate device or have different technological characteristics and not raise different questions of safety or effectivenessthan the predicate device. Clinical data are sometimes required to support substantial equivalence.After a 510(k) notice is submitted, the FDA determines whether to accept it for substantive review. If it lacks necessary information for substantivereview, the FDA will refuse to accept the 510(k) notification. If it is accepted for filing, the FDA begins a substantive review. By statute, the FDA is requiredto complete its review of a 510(k) notification within 90 days of receiving the 510(k) notification. As a practical matter, clearance often takes longer, andclearance is never assured. Although many 510(k) premarket notifications are cleared without clinical data, the FDA may require further information,including clinical data, to make a determination regarding substantial equivalence, which may significantly prolong the review process. If the FDA agreesthat the device is substantially equivalent, it will grant clearance to commercially market the device.21After a device receives 510(k) clearance, any modification that could significantly affect its safety or effectiveness, or that would constitute a new ormajor change in its intended use, will require a new 510(k) clearance or, depending on the modification, could require a PMA application. The FDA requireseach manufacturer to make this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. Ifthe FDA disagrees with a manufacturer’s determination regarding whether a new premarket submission is required for the modification of an existing device,the FDA can require the manufacturer to cease marketing and/or recall the modified device until 510(k) clearance or approval of a PMA application isobtained. If the FDA requires us to seek 510(k) clearance or approval of a PMA application for any modifications to a previously cleared product, we may berequired to cease marketing or recall the modified device until we obtain this clearance or approval. In addition, in these circumstances, we may be subject tosignificant regulatory fines or penalties for failure to submit the requisite PMA application(s). In addition, the FDA is currently evaluating the 510(k) processand may make substantial changes to industry requirements.The PMA ProcessIf the FDA determines that the device is not “substantially equivalent” to a predicate device, or if the device is classified into Class III, the devicesponsor must then fulfill the much more rigorous premarketing requirements of the PMA process, or seek reclassification of the device through the de novoprocess. A manufacturer can also submit a petition for direct de novo review if the manufacturer is unable to identify an appropriate predicate device and thenew device or new use of the device presents a moderate or low risk.Class III devices include devices deemed by the FDA to pose the greatest risk such as life-supporting or life-sustaining devices, or implantabledevices, in addition to those deemed not substantially equivalent following the 510(k) process. The safety and effectiveness of Class III devices cannot bereasonably assured solely by the General Controls and Special Controls described above. Therefore, these devices are subject to the PMA application process,which is generally costlier and time consuming than the 510(k) process. Through the PMA application process, the applicant must submit data andinformation demonstrating reasonable assurance of the safety and effectiveness of the device for its intended use to the FDA’s satisfaction. Accordingly, aPMA application typically includes, but is not limited to, extensive technical information regarding device design and development, pre-clinical and clinicalstudy data, manufacturing information, labeling and financial disclosure information for the clinical investigators in device studies. The PMA applicationmust provide valid scientific evidence that demonstrates to the FDA’s satisfaction reasonable assurance of the safety and effectiveness of the device for itsintended use.In the United States, absent certain limited exceptions, human clinical studies intended to support medical device clearance or approval require anInvestigational Device Exemption (“IDE”) application. Some types of studies deemed to present “non-significant risk” are deemed to have an approved IDEonce certain requirements are addressed and Institutional Review Board approval is obtained. If the device presents a “significant risk” to human health, asdefined by the FDA, the sponsor must submit an IDE application to the FDA and obtain IDE approval prior to commencing the human clinical studies. TheIDE application must be supported by appropriate data, such as animal and laboratory testing results, showing that it is safe to test the device in humans andthat the testing protocol is scientifically sound. The IDE application must be approved in advance by the FDA for a specified number of subjects. Generally,clinical studies for a significant risk device may begin once the IDE application is approved by the FDA and the study protocol and informed consent areapproved by appropriate institutional review boards at the clinical study sites. There can be no assurance that submission of an IDE will result in the abilityto commence clinical studies, and although the FDA’s approval of an IDE allows clinical testing to go forward for a specified number of subjects, it does notbind the FDA to accept the results of the trial as sufficient to prove the product’s safety and efficacy, even if the trial meets its intended success criteria.Following receipt of a PMA application, the FDA conducts an administrative review to determine whether the application is sufficiently complete topermit a substantive review. If it is not, the agency will refuse to file the PMA. If the PMA application is determined to be sufficiently complete, the FDA willaccept the application for filing and begin the review. The FDA, by statute and by regulation, has 180 days to review a filed PMA application, although thereview of an application more often occurs over a significantly longer period. During this review period, the FDA may request additional information orclarification of information already provided, and the FDA may issue a major deficiency letter to the applicant, requesting the applicant’s response todeficiencies communicated by the FDA. The FDA considers a PMA or PMA supplement to have been voluntarily withdrawn if an applicant fails to respond toan FDA request for information (e.g. major deficiency letter) within a total of 360 days. Before approving or denying a PMA, an FDA advisory panel may beconvened to review the PMA and provide the FDA with the committee’s recommendation on whether the FDA should approve the submission, approve itwith specific conditions, or not approve it. This advisory panel may also involve a public meeting if FDA determines public input is required. Prior toapproval of a PMA, the FDA may conduct a bioresearch monitoring inspection of the clinical study data and clinical study sites, and a QSR inspection of themanufacturing facility and processes. Overall, the FDA review of a PMA application generally takes between one and three years, but may take significantlylonger. The FDA can delay, limit or deny approval of a PMA application for many reasons, including: •the device may not be shown safe or effective to the FDA’s satisfaction; •the data from pre-clinical studies and clinical studies may be insufficient to support approval;22 •the manufacturing process or facilities may not meet applicable requirements; and •changes in FDA approval policies or adoption of new regulations may require additional data.If the FDA evaluation of a PMA is favorable, the FDA will issue either an approval letter, or an approvable letter, which usually contains severalconditions that must be met in order to secure final approval of the PMA. When and if those conditions have been fulfilled to the satisfaction of the FDA, theagency will issue a PMA letter authorizing commercial marketing of the device, subject to the conditions of approval and the limitations established in theapproval letter. If the FDA’s evaluation of a PMA application or manufacturing facilities is not favorable, the FDA will deny approval of the PMA or issue anot approvable letter. The FDA also may determine that additional analytical studies or clinical studies are necessary, in which case approval of the PMAsubmission may be delayed for several months or years while the analytical studies and/or trials are conducted and data are submitted in an amendment to thePMA. The PMA process can be expensive, uncertain and lengthy and a number of devices for which FDA approval has been sought by other companies havenever been approved by the FDA for marketing.New PMA applications or PMA supplements may be required for modification to the manufacturing process, labeling, device specifications, materialsor design of a device that has been approved through the PMA process. PMA supplements often require submission of the same type of information as aninitial PMA application, except that the supplement is limited to information needed to support any changes from the device covered by the approved PMAapplication and may or may not require as extensive technical or clinical data or the convening of an advisory panel, depending on the nature of theproposed change.In approving a PMA application, the FDA may also require some form of post market studies or post market surveillance, whereby the applicantfollows certain patient groups for several years and makes periodic reports to the FDA on the clinical status of those patients when necessary to protect thepublic health or to provide additional safety and effectiveness data for the device. FDA may also require post market surveillance for certain devices clearedunder a 510(k) notification, such as implants or life-supporting or life-sustaining devices used outside a device user facility. The FDA may also approve aPMA application with other post-approval conditions intended to ensure the safety and effectiveness of the device, such as, among other things, restrictionson labeling, promotion, sale, distribution and use.Post-Approval RequirementsAfter the FDA permits a device to enter commercial distribution, numerous regulatory requirements apply. These include, but are not limited to: •the registration and listing regulation, which requires manufacturers to register all manufacturing facilities and list all medical devices placedinto commercial distribution; •the QSR, which requires manufacturers, including third party manufacturers, to follow elaborate design, testing, production, control,supplier/contractor selection, complaint handling, documentation and other quality assurance procedures during the manufacturing process; •labeling regulations and unique device identification requirements; •advertising and promotion requirements; •restrictions on sale, distribution or use of a device; •PMA annual reporting requirements; •the FDA’s general prohibition against promoting products for unapproved or “off-label” uses; •the Medical Device Reporting (“MDR”) regulation, which requires that manufacturers report to the FDA if their device may have caused orcontributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were toreoccur; •medical device correction and removal reporting regulations, which require that manufacturers report to the FDA field corrections and productrecalls or removals if undertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk tohealth; •recall requirements, including a mandatory recall if there is a reasonable probability that the device would cause serious adverse healthconsequences or death; •an order of repair, replacement or refund; •device tracking requirements; and •post-approval study and post market surveillance requirements.23Our facilities, records and manufacturing processes are subject to periodic unscheduled inspections by the FDA. Failure to comply with the applicableUnited States medical device regulatory requirements could result in, among other things, warning letters, untitled letters, fines, injunctions, consent decrees,civil penalties, unanticipated expenditures, repairs, replacements, refunds, recalls or seizures of products, operating restrictions, total or partial suspension ofproduction, the FDA’s refusal to issue certificates to foreign governments needed to export products for sale in other countries, the FDA’s refusal to grantfuture premarket clearances or approvals, withdrawals or suspensions of current product clearances or approvals and criminal prosecution.Research Use OnlyAn RUO product is one that is not intended for clinical diagnostic use and must be labeled “For Research Use Only. Not for use in diagnosticprocedures.” Products that are intended for research use only and are properly labeled as RUO are exempt from compliance with the FDA requirementsdiscussed above, including the approval or clearance and QSR requirements. A product labeled RUO but intended to be used diagnostically may be viewedby the FDA as adulterated and misbranded under the FDC Act and is subject to FDA enforcement activities. The FDA may consider the totality of thecircumstances surrounding distribution and use of an RUO product, including how the product is marketed, when determining its intended use.European UnionThe European Union (“EU”) has also adopted requirements that affect our products. These requirements include establishing standards that addresscreating a certified quality system as well as several directives that address specific product areas. The most significant of these currently effective directivesis the In Vitro Diagnostic Medical Device Directive (“IVDD”) which includes: •Essential Requirements. The IVDD specifies “essential requirements” that all medical devices must meet. The requirements are similar to thoseadopted by the FDA relating to quality systems and product labeling. •Conformity Assessment. Unlike United States regulations, which require virtually all devices to undergo some level of premarket review by theFDA, the IVDD currently allows manufacturers to bring many devices to market using a process in which the manufacturer certifies that thedevice conforms to the essential requirements for that device. A small number of products must go through a more formal pre-market reviewprocess. Devices that comply with the requirements of a relevant directive will be entitled to bear the CE conformity marking, indicating thatthe device conforms to the essential requirements of the applicable directives and, accordingly, can be marketed throughout the EU andEuropean Economic Area. •Vigilance. The IVDD also specifies requirements for post market reporting similar to those adopted by the FDA.On May 26, 2017, the EU released a new regulatory framework, the In Vitro Diagnostic Medical Device Regulation (“IVDR”) which is expected toreplace IVDD. Our products in the EU will have to comply with the IVDR requirements after May 26, 2022. Until that time, our products must continue tomeet the requirements of IVDD for commercialization in the EU.Other InternationalSeveral other countries, including Australia, Canada, China and Japan, have adopted or are in the process of adopting standards for medical devicessold in those countries. Many of these standards are loosely patterned after those adopted by the European Union, but with elements unique to each country.Although there is a trend towards harmonization of quality system standards, regulations in each country may vary substantially, which can affect timelinesof introduction. We routinely monitor these developments and address compliance with the various country requirements as new standards are adopted.Government Regulation – Fraud and Abuse and Other Healthcare RegulationWe may be subject to various federal and state healthcare laws, including, but not limited to, anti-kickback laws. Penalties for violations of thesehealthcare laws include, but are not limited to, criminal, civil and/or administrative penalties, damages, fines, disgorgement, individual imprisonment,possible exclusion from Medicare, Medicaid and other federal healthcare programs, additional reporting requirements and/or oversight if we become subjectto a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws and the curtailment or restructuring ofoperations.Federal Anti-Kickback StatuteThe Federal Anti-Kickback Statute prohibits persons or entities from knowingly and willfully soliciting, offering, receiving or paying anyremuneration, directly or indirectly, overtly or covertly, in cash or in kind, in exchange for or to induce either the referral of an individual, or the furnishing,arranging for or recommending a good or service, or for the purchasing, leasing, ordering, or arranging for or recommending, any good, facility, service oritem for which payment may be made in whole or in part under federal24healthcare programs, such as the Medicare and Medicaid programs. The Federal Anti-Kickback Statute is broad and prohibits many arrangements andpractices that are lawful in businesses outside of the healthcare industry. The term “remuneration” expressly includes kickbacks, bribes, or rebates and hasbeen broadly interpreted to include anything of value, including for example, gifts, discounts, the furnishing of supplies or equipment, credit arrangements,payments of cash, waivers of payments, ownership interests and providing anything at less than its fair market value.There are several statutory exceptions and regulatory safe harbors protecting certain business arrangements from prosecution under the Federal Anti-Kickback Statute. These statutory exceptions and safe harbors set forth provisions that, if all their applicable requirements are met, will assure healthcareproviders and other parties that they may not be prosecuted under the Federal Anti-Kickback Statute. The failure of a transaction or arrangement to fitprecisely within one or more applicable statutory exceptions or regulatory safe harbors does not necessarily mean that it is illegal or that prosecution will bepursued. However, conduct and business arrangements that do not fully satisfy all requirements of an applicable safe harbor may result in increased scrutinyby government enforcement authorities and will be evaluated on a case-by-case basis based on a cumulative review of all of its facts and circumstances.Additionally, the intent standard under the Federal Anti-Kickback Statute was amended under the Patient Protection and Affordable Care Act, as amended bythe Health Care and Education Reconciliation Act, (collectively the “ACA”) to a stricter standard such that a person or entity no longer needs to have actualknowledge of the statute or specific intent to violate it in order to have committed a violation. Further, the intent to induce referrals need only be “onepurpose” of the remuneration for violations of the Federal Anti-Kickback Statute. The ACA provides that the government may assert that a claim includingitems or services resulting from a violation of the Federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal civil FalseClaims Act which is discussed below.Federal Civil False Claims ActThe federal civil False Claims Act prohibits, among other things, persons or entities from knowingly presenting or causing to be presented a false orfraudulent claim to, or the knowing use of false statements to obtain payment from or approval by the Federal Government. Suits filed under the federal civilFalse Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of the government. These individuals, sometimes known as“relators” or, more commonly, as “whistleblowers”, may share in any amounts paid by the entity to the government in fines or settlement. The number offilings of qui tam actions has increased significantly in recent years, causing more healthcare companies to have to defend a case brought under the federalcivil False Claim Act. If an entity is determined to have violated the federal civil False Claims Act, it may be required to pay up to three times the actualdamages sustained by the government, plus civil penalties for each separate false claim. Many comparable state laws are broader in scope and apply to allpayors, and therefore, are not limited to only those claims submitted to the Federal Government.Federal Physician Self-Referral ProhibitionWe are also subject to the federal physician self-referral prohibitions, commonly known as the Stark Law, which prohibits, among other things,physicians who have a financial relationship, including an investment, ownership or compensation relationship with an entity, from referring Medicare andMedicaid patients to the entity for designated health services, which include clinical laboratory services, unless an exception applies. Similarly, entities maynot bill Medicare, Medicaid or any other party for services furnished pursuant to a prohibited referral. Many states have their own self-referral laws as well,which in some cases apply to all third-party payors, not just Medicare and Medicaid.Federal Civil Monetary Penalties StatuteThe Federal Civil Monetary Penalties Statute, among other things, imposes fines against any person or entity who is determined to have presented, orcaused to be presented, claims to a federal healthcare program that the person knows, or should know, is for an item or service that was not provided asclaimed or is false or fraudulent.Health Insurance Portability and Accountability Act of 1996The Federal Health Insurance Portability and Accountability Act (“HIPAA”) created several additional federal crimes, including healthcare fraud andfalse statements relating to healthcare matters. The healthcare fraud statute prohibits knowingly and willfully executing a scheme to defraud any healthcarebenefit program, including private third-party payors. The false statements statute prohibits knowingly and willfully falsifying, concealing or covering up amaterial fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items orservices.In addition, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act (“HITECH”) and their implementingregulations established uniform standards for certain covered entities, which are certain healthcare providers, health plans and healthcare clearinghouses, aswell as their business associates that perform services for them that involve the creation, use, maintenance or disclosure of, individually identifiable healthinformation, governing the conduct of specified electronic25healthcare transactions and protecting the security and privacy of protected health information. Among other things, HITECH also created four new tiers ofcivil monetary penalties and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce federalHIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions. The EU has established its own data security and privacy legalframework, including but not limited to Directive 95/46/EC (“Data Protection Directive”). The Data Protection Directive will be replaced starting in May2018 with the recently adopted European General Data Protection Regulation (“GDPR”), which contains new provisions specifically directed at theprocessing of health information, higher sanctions and extra-territoriality measures intended to bring non-EU companies under the regulation. Over time wemay expand our business operations to include additional operations in the EU. With such expansion, we would be subject to increased governmentalregulation, including the GDPR, in the EU countries in which we operate.The Federal Physician Payments Sunshine ActThe Federal Physician Payments Sunshine Act requires certain manufacturers of drugs, devices, biologics and medical supplies for which payment isavailable under Medicare, Medicaid or the Children’s Health Insurance Program, with certain exceptions, to report annually to CMS, information related to“payments or other transfers of value” provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teachinghospitals, and applicable manufacturers and group purchasing organizations to report annually to CMS ownership and investment interests held byphysicians, as defined above, and their immediate family members. Failure to submit timely, accurately and completely the required information for allpayments, transfers of value and ownership or investment interests may result in significant civil monetary penalties.State Law EquivalentsMany states have also adopted laws similar to each of the above federal laws, such as anti-kickback and false claims laws, which may be broader inscope and apply to items or services reimbursed by any third-party payor, including commercial insurers, as well as laws that restrict our marketing activitieswith health care professionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided tohealthcare professionals and entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. We also are subjectto foreign fraud and abuse laws, which vary by country. We may be subject to certain state and foreign laws governing the privacy and security of healthinformation in some circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicatingcompliance efforts.Healthcare ReformIn March 2010, President Obama enacted the ACA, which is substantially changing healthcare financing and delivery by both governmental andprivate insurers, and is significantly impacting the medical device industry. The ACA’s provisions of importance to our business include, but are not limitedto, a deductible 2.3% excise tax on any entity that manufactures or imports medical devices offered for sale in the United States, with limited exceptions,which became effective January 1, 2013. However, the Consolidated Appropriations Act of 2016, signed into law in December 2015, includes a two-yearmoratorium on the medical device excise tax that applies between January 1, 2016 and December 31, 2017. Further, on January 22, 2018, President Trumpsigned a continuing resolution on appropriations for fiscal year 2018, the 2018 Appropriations Resolution, that extended the moratorium on the medicaldevice excise tax through December 31, 2019. Absent further legislative action, the tax will be automatically reinstated for medical device sales beginningJanuary 1, 2020.Since its enactment in 2010, there have been judicial and Congressional challenges to certain aspects of the ACA. Since January 2017, PresidentTrump has signed two Executive Orders and other directives designed to delay the implementation of certain provision of the ACA and otherwise circumventsome of the requirements for health insurance mandated by the ACA. Concurrently, Congress has considered legislation that would repeal or repeal andreplace all or part of the ACA. While Congress has not passed comprehensive repeal legislation, two bills affecting the implementation of certain taxes underthe ACA have been signed into law. The 2017 U.S. Tax Cuts and Jobs Act (the “2017 Tax Act”) includes a provision repealing, effective January 1, 2019, thetax-based shared responsibility payment imposed by the ACA on certain individuals who fail to maintain qualifying health coverage for all or part of a yearthat is commonly referred to as the “individual mandate”. Additionally, the 2018 Appropriations Resolution delays the implementation of certain ACA-mandated fees, including, without limitation, the medical device excise tax.In addition, other legislative changes have been proposed and adopted since the ACA was enacted. On August 2, 2011, President Obama signed intolaw the Budget Control Act of 2011, which, among other things, created the Joint Select Committee on Deficit Reduction to recommend to Congressproposals in spending reductions. The Joint Select Committee did not achieve a targeted deficit reduction of at least $1.2 trillion for the years 2013 through2021, triggering the legislation’s automatic reduction to several government programs. This includes reductions to Medicare payments to providers of2% per fiscal year, which went into effect on April 1, 2013, and, following the passage of other legislative amendments, including the Bipartisan Budget Actof 2018, will stay in effect through 2027 unless additional Congressional action is taken. On January 2, 2013, President Obama signed into law the26American Taxpayer Relief Act of 2012, which, among other things, further reduced Medicare payments to several providers, including hospitals, imagingcenters and cancer treatment centers and increased the statute of limitations period for the government to recover overpayments to providers from three to fiveyears.The full impact of the ACA, its possible repeal, and any legislation passed to replace the ACA, as well as other laws and reform measures that may beproposed and adopted in the future, remains uncertain, but may continue the downward pressure on medical device pricing, especially under the Medicareprogram, and may also increase our regulatory burdens and operating costs, which could have a material adverse effect on our business operations.The Foreign Corrupt Practices ActThe Foreign Corrupt Practices Act (“FCPA”) prohibits any U.S. individual or business from paying, offering, or authorizing payment or offering ofanything of value, directly or indirectly, to any foreign official, political party or candidate for the purpose of influencing any act or decision of the foreignentity to assist the individual or business in obtaining or retaining business. The FCPA also obligates companies whose securities are listed in the UnitedStates to comply with accounting provisions requiring the company to maintain books and records that accurately and fairly reflect all transactions of thecorporation, including international subsidiaries, and to devise and maintain an adequate system of internal accounting controls for international operations.EmployeesOur ability to retain current talent and recruit new employees into our Company is a critical factor in our continued growth and performanceimprovement. We continue to initiate programs to promote our organizational culture and to identify the best possible new talent as the organization growsand new positions are made available. As of December 31, 2017, we had 94 full-time and four part-time employees, of which 12 are employed inadministration, 22 in manufacturing and operations, 30 in research and development, six in regulatory and quality affairs, and 28 in sales and marketing. Wehad five employees in Europe as of December 31, 2017, all others were in the United States. We believe that our success will depend, in part, on our ability toattract and retain qualified personnel. We have never experienced a work stoppage due to labor difficulties and believe that our relations with our employeesare good. None of our U.S. employees are represented by labor unions. Collective bargaining is established by law in France. We and our French employeeshave agreed to the terms of the applicable collective bargaining agreements.Corporate InformationWe were originally incorporated in Arizona in October 1997 as “High Throughput Genomics, Inc.” In December 2000, we reincorporated in Delawareas “HTG, Inc.” and in March 2011 we changed our name to “HTG Molecular Diagnostics, Inc.” Our principal executive offices are located at 3430 E.

Risk Factors.An investment in shares of our common stock involves a high degree of risk. You should carefully consider the following risk factors, as well as theother information in this report, and in our other public filings, before deciding to purchase, hold or sell shares of our common stock. The occurrence of anyof the following risks could have a material adverse effect on our business, financial condition, results of operations and future growth prospects or causeour actual results to differ materially from those contained in forward-looking statements we have made in this report and those we may make from time totime. In these circumstances, the market price of our common stock could decline, and you may lose all or part of your investment. You should consider all ofthe risk factors described when evaluating our business.Risks Related to our Business and StrategyWe have incurred losses since our inception and expect to incur losses for the foreseeable future. We cannot be certain that we will achieve or sustainprofitability.We have incurred losses since our inception and expect to incur losses in the future. We incurred net losses of $19.0 million and $26.0 million for theyears ended December 31, 2017 and 2016, respectively. As of December 31, 2017, we had an accumulated deficit of $134.6 million. We expect that ourlosses will continue for the foreseeable future as we will be required to invest significant additional funds to support product development, includingdevelopment of our next generation instrument platforms, development of our new HTG EdgeSeq panels, including our initial U.S. IVD assay, developmentof assays pursuant to our Governing Agreement with QML, and the commercialization of our HTG EdgeSeq system and proprietary consumables. We alsoexpect that our selling, general and administrative expenses will continue to increase due to the additional costs associated with market developmentactivities and expanding our staff to sell and support our products and services. Our ability to achieve or, if achieved, sustain profitability is based onnumerous factors, many of which are beyond our control, including the market acceptance of our products and services, competitive product developmentand our market penetration and margins. We may never be able to generate sufficient revenue to achieve or, if achieved, sustain profitability.We have limited experience in marketing and selling our products, and if we are unable to successfully commercialize our products, our business may beadversely affected.We have limited experience marketing and selling our products. Our HTG Edge system was introduced for sale in the life sciences research market inthe third quarter of 2013. Our HTG EdgeSeq chemistry was introduced for sale in the life sciences research market in the third quarter of 2014. Our dedicatedHTG EdgeSeq system was introduced for sale in the life sciences research market in the fourth quarter of 2015 and has been our primary product focus since2016. Our VERI/O service laboratory was announced in June 2016. We currently market our products through our own sales force in the United States andEurope, and have distributors in parts of Europe and the Middle East. In the future, we intend to expand our sales and support team in the United States,continue to build a direct sales and support team in Europe and establish additional distributor and/or third party contract sales team relationships in otherparts of the world. However, we may not be able to market and sell our products effectively. Our sales of life science research products and potential futurediagnostic products will depend in large part on our ability to successfully increase the scope of our marketing efforts and establish and maintain a sales forcecommensurate with our then applicable markets. Because we have limited experience in marketing and selling our products in the life science researchmarket and in marketing and selling our products in the diagnostic market, our ability to forecast demand, the infrastructure required to support such demandand the sales cycle to customers is unproven. If we do not build an efficient and effective sales force and distributor relationships targeting these markets, ourbusiness and operating results will be adversely affected.If we do not obtain regulatory clearance or approval to market our products for diagnostic purposes, we will be limited to marketing our products forresearch use only. In addition, if regulatory limitations are placed on our diagnostic products our business and growth will be harmed.In many jurisdictions, including the United States, we are currently limited to marketing our HTG EdgeSeq system and proprietary profiling panels forresearch use only, which means that we cannot make any diagnostic or clinical claims for those products in those jurisdictions. We have sought and intend tocontinue to seek regulatory clearances or approvals in the United States and other jurisdictions to market certain panels for diagnostic purposes; however, wemay not be successful in doing so.The FDA regulates diagnostic kits sold and distributed through interstate commerce in the United States as medical devices. Unless an exemptionapplies, generally, before a new medical device may be sold or distributed in the United States, or may be marketed for a new use in the United States, themedical device must receive either FDA clearance of a 510(k) pre-market notification or pre-market approval. Thus, before we can market or distribute ourprofiling panels, including our mRNA and miRNA panels, as IVD kits for use by clinical testing laboratories in the United States, we must first obtain pre-market clearance or pre-market approval from the FDA. Even if or when we apply for clearance or approval from the FDA for any of our products, the processcan be lengthy and unpredictable. We are working collaboratively with multiple biopharmaceutical companies to clinically validate our28HTG EdgeSeq DLBCL Cell of Origin Assay, which we believe can classify DLBCL as either ABC or GCB subtype. We expect to submit the DLBCL assay forU.S. regulatory clearances or approvals at some future time if and when our work with the biopharmaceutical companies reaches an appropriate stage. Weinitiated a modular PMA submission process to obtain FDA approval of our HTG EdgeSeq ALKPlus Assay to detect certain gene fusions in lung cancer in2016. We cannot provide any assurances that our clinical studies or collaborative development services with biopharmaceutical companies will becompleted or, if completed, have the desired outcomes or that we will meet the regulatory clearance or approval timelines for either product. Further, even ifwe complete the requisite clinical validations and submit or complete submission of an application, we may not receive FDA clearance or approval for thecommercial use of our tests on a timely basis, or at all. If we are unable to obtain regulatory clearance or approval, or if clinical diagnostic laboratories do notaccept our cleared or approved tests, our ability to grow our business could be compromised.Similarly, foreign countries have either implemented or are in the process of implementing increased regulatory controls that require that we submitapplications for review and approval by foreign regulatory bodies. We obtained the right to CE mark the HTG EdgeSeq DLBCL Cell of Origin Assay EU andthe HTG EdgeSeq ALKPlus Assay EU for sale as IVDs in Europe, in July 2016 and March 2017, respectively. If we are unable to maintain CE marking orachieve appropriate ex-U.S. approvals on any of our products for their intended commercial uses on a timely basis or at all, or if clinical diagnosticlaboratories or other customers outside the United States do not accept our tests, our ability to grow our business outside of the United States could becompromised.Clinical studies of any product candidate that we intend to market as an IVD kit may not be successful. If we are unable to successfully complete non-clinical and clinical studies of our product candidates or experience significant delays in doing so, our business will be materially harmed.Our clinical diagnostic business prospects in the United States and other applicable jurisdictions will depend on our ability to successfully completeclinical studies for product candidates that we intend to market as IVD kits. A failure of one or more clinical studies can occur at any stage of testing. Theoutcome of non-clinical studies may not be predictive of the success of clinical studies, and interim results, if any, of a clinical study do not necessarilypredict final results. Moreover, non-clinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that havebelieved their product candidates performed satisfactorily in non-clinical and clinical studies have nonetheless failed to obtain pre-marketing clearance orapproval for their products. Completion of clinical studies, announcement of results of the studies and our ability to obtain regulatory approvals could bedelayed for a variety of reasons, including: •unsatisfactory results of any clinical study, including failure to meet study objectives; •the failure of our principal third-party investigators to perform our clinical studies on our anticipated schedules; •imposition of a clinical hold following an inspection of our clinical study operations or trial sites by the FDA or other regulatory authorities; •our inability to adhere to clinical study requirements directly or with third parties, such as contract research organizations; •different interpretations of our non-clinical and clinical data, which could initially lead to inconclusive results; and •delays in obtaining suitable patient samples for use in a clinical study.Our development costs will increase if we have material delays in any clinical study or if we need to perform more or larger clinical studies thanplanned. If the delays are significant, or if any of our products do not prove to be equivalent to a predicate device or safe or effective, as applicable, or do notreceive required regulatory approvals, our financial results and the commercial prospects for our product candidates will be harmed. Furthermore, ourinability to complete our clinical studies in a timely manner could jeopardize our ability to obtain regulatory approval.If our HTG EdgeSeq system and proprietary profiling panels fail to achieve and sustain sufficient market acceptance, or we are not able to continue toexpand our service relationships with biopharmaceutical customers (including indirectly pursuant to our Governing Agreement), we will not generateexpected revenue, and our prospects may be harmed.We are currently focused on selling our HTG EdgeSeq system and profiling panels within the life sciences research market. We plan to develop panelsfor many different disease states including companion diagnostics to determine the proper course of treatment for those diseases. We may experiencereluctance, or refusal, on the part of physicians to order, and third-party payors to cover and provide adequate reimbursement for, our panels if the results ofour research and clinical studies, and our sales and marketing activities relating to communication of these results, do not convey to physicians, third-partypayors and patients that the HTG EdgeSeq system and related profiling panels provide equivalent or better diagnostic information than other availabletechnologies and methodologies. We believe our panels represent an emerging methodology in diagnosing disease states, and we may have to overcomeresistance among physicians to adopting it for the marketing of our products to be successful. Even if we are able to obtain regulatory approval from the FDA,the use of our panels may not become the standard diagnostic tool for those diseases on which we plan to focus our efforts.29In addition, a key component of our strategy is to develop diagnostic tools in conjunction with biopharmaceutical companies’ drug developmentprograms, to help assess the proper course of treatment for specific diseases. Even if we are successful in developing those diagnostic tools and receiveregulatory approval, we still may not be successful in marketing those diagnostic tests. Furthermore, the decision to advance an underlying drug candidatethrough clinical trials and ultimately to commercialization is in the discretion of biopharmaceutical companies with which we collaborate. Ourbiopharmaceutical partners may take certain actions that could negatively impact the utility and marketability of our diagnostic tests. For example, ourbiopharmaceutical partners could: •determine not to actively pursue the development or commercialization of an applicable drug candidate, including due to the failure todemonstrate sufficient efficacy, the occurrence of safety or tolerability issues, or any number of other reasons; •fail to obtain necessary regulatory approval of an applicable drug candidate; •obtain regulatory approval for a drug candidate in a manner that neither requires nor recommends the use of a companion diagnostic test priorto its use; or •choose alternative diagnostic tests to market with their products instead of ours.To the extent that we develop diagnostic assays for a biopharmaceutical company in collaboration with QML under our Governing Agreement andrelated statements of work, we may not have responsibility for some or all aspects of developing, marketing or commercializing any resulting diagnostic tests.In addition to this biopharmaceutical partner risk, QML may take certain actions that could negatively impact the development, utility and marketability ofthe applicable diagnostic tests. For example, QML could fail to satisfy or fall behind in its obligations to us or to the biopharmaceutical partner, which maydelay development, regulatory approvals, market development and/or commercialization of an applicable companion diagnostic test.Any of these events could limit our diagnostic test sales and revenues and have a material adverse effect on our business, operating results andfinancial condition.We are dependent on our Governing Agreement with QML, and poor performance under the agreement or the termination of the agreement couldnegatively impact our business.A key strategic focus of our business is to enter into collaborative development agreements with biopharmaceutical companies for the development,manufacture and commercialization of companion diagnostic assays for use with their drug development programs. In particular, we are focused ononcology-based collaborations.In November 2016, we entered into a Governing Agreement with QML. Under the Governing Agreement, we and QML jointly seek collaborativedevelopment agreements with biopharmaceutical companies for the development, manufacture and potential commercialization of companion diagnosticassays. QML contracts with interested biopharmaceutical companies for specified projects, and we and QML enter into statements of work for each project.Our relationship with QML under the Governing Agreement is exclusive for NGS-based diagnostic assays (or certain related research assays) in the oncologyfield, subject to the achievement of certain performance targets. We expect that revenues under the Governing Agreement will constitute a significant portionof our revenues over at least the next few years.We have limited or no control over the amount and timing of resources that QML will dedicate to activities under the Governing Agreement, and weare subject to a number of other risks associated with our dependence on the Governing Agreement, including: •There could be disagreements regarding the Governing Agreement, the initiation or conduct of activities under statements of work for specifiedprojects, the achievement of milestone or other payments, the ownership of intellectual property, or research and development, regulatory,commercialization or other strategy. These disagreements might delay or terminate the development, manufacture or commercialization ofcompanion diagnostic assays, delay or eliminate potential payments under the Governing Agreement or increase our costs under or outside ofthe Governing Agreement; •QML may not allocate adequate resources or otherwise support the development of collaborations with biopharmaceutical companies,including if they no longer view our Governing Agreement as in their best financial or other interests; and •QML may not perform as expected, including with regard to making any required payments, or performing its development or other obligationsunder a statement of work or under the contract with the applicable biopharmaceutical company customer and the Governing Agreement orapplicable statement of work may not provide adequate protection for us or may not be effectively enforced.In addition, we and QML have the right to terminate the Governing Agreement in certain circumstances. If the Governing Agreement is terminatedearly, we may not be able to find another company to assist us with the development, manufacture and commercialization of companion diagnostic assays forbiopharmaceutical companies should we wish to do so. If we fail maintain a30successful relationship with QML under the Governing Agreement, our development, manufacture and commercialization of companion diagnostic assaysmay be delayed, scaled back, or otherwise may not occur, and our anticipated revenue from the Governing Agreement could be severely limited oreliminated. In addition, we may be unable to enter into new collaborative arrangements with biopharmaceutical companies or, if necessary, modify ourexisting arrangements on acceptable terms. Any of these could have a material adverse effect on our business, results of operations and financial condition.Our HTG EdgeSeq product portfolio requires the use of NGS instrumentation and reagents and could be adversely affected by actions of third party NGSproduct manufacturers over whom we have no control.A key element of our strategy is to establish our HTG EdgeSeq system as the best sample and library preparation method for clinical applications ofnext generation sequencers. We depend at least in part on the availability of NGS instrumentation and reagents, and the ability of our HTG EdgeSeq productsto operate seamlessly with NGS instrumentation. Any significant interruption or delay in the ability of our HTG EdgeSeq products to operate on or with NGSinstrumentation could reduce demand for our products and result in a loss of customers.Our reputation, and our ability to continue to establish or develop our technology for clinical applications of next generation sequencers, aredependent upon the availability of NGS instrumentation and the reliable performance of our products with NGS instrumentation. We are not able to controlthe providers of NGS instrumentation, which increases our vulnerability to interoperability problems with the products that they provide. For example,providers of NGS instruments may discontinue existing products, or introduce new NGS instrumentation products with little or no notice to us. This maycause some of our products not to be operable with one or more NGS instruments or may adversely affect regulatory approvals of our future IVD HTGEdgeSeq products, potentially for extended periods of time. Any interruption in the ability of our products to operate on NGS instruments could harm ourreputation or decrease market acceptance of our products, and our business, financial condition and operating results may be materially and adverselyaffected. We also could experience additional expense in developing new products or changes to existing products to meet developments in NGSinstrumentation, and our business, financial condition and operating results may be materially and adversely affected.Current medical device regulation in the United States and other jurisdictions requires manufacturers of IVD molecular profiling tests that use NGSdetection, referred to as NGS IVD tests, to include in regulatory submissions, technical information about the NGS products that are required for performanceof, but are not supplied with, the NGS IVD test. These regulatory agencies also require that the NGS instrumentation have “locked” software for the detectionof the NGS IVD test results. Thus, to obtain regulatory approval for NGS IVD tests, manufacturers like us, currently must have arrangements with NGS productmanufacturers to gain access to technical information and NGS instrument software. We currently have agreements with two NGS product manufacturers thatgrant us rights to develop, manufacture and sell future HTG EdgeSeq NGS IVD tests in specified fields, subject to, among other things, the NGS productmanufacturers’ rights to terminate such agreements and discontinue products or implement product design changes that could adversely affect our HTGEdgeSeq NGS IVD tests. There can be no assurance that our agreements with these NGS product manufacturers, or any future NGS product manufacturers thatwe contract with, will not be terminated earlier than we currently expect, that a NGS product manufacturer will perform its contractual duties to us, or that wewill otherwise receive the benefits we anticipate receiving under those agreements. In addition, if regulatory agencies do not change their requirements forNGS IVD test approval or clearance and the NGS instrument manufacturers close their systems to third party NGS IVD test development (in general or withspecific NGS IVD test manufacturers) and we are not able to maintain or enforce our agreements with such manufacturers, we may not be able to meet ourcommercial goals and our business, financial condition and operating results may be materially and adversely affected.The development of future products is dependent on new methods and/or technologies that we may not be successful in developing.We are planning to expand our product offerings in the fields of detecting expressed gene rearrangements (e.g., gene fusions and/or insertions) andgenomic or expressed DNA mutations. We believe we have successfully demonstrated that our technology is able to detect certain expressed generearrangements with our HTG EdgeSeq ALKPlus Assay EU now available in Europe, and genomic DNA mutations with our HTG EdgeSeq EGFR,KRAS and BRAF Mutation Assay service offering. Nevertheless, there are other potential applications for the foregoing technologies and opportunity foradditional technology developments, such as detection of expressed DNA mutations, methods to detect mutation load and microsatellite instability andmultiparameter testing methods, that we consider when planning our product pipeline. We believe we have successfully demonstrated proof of concept fordetection of express DNA mutations but to date our work in this area has only been on relatively few applications or may not have the specificity required forcertain applications. We cannot guarantee that we will be able to successfully develop additional applications or new technologies on a commercial scale. Ifwe are unsuccessful at developing additional applications involving gene rearrangements or genomic DNA mutations, or developing technology to detectexpressed DNA mutations, mutation load and microsatellite instability or developing multiparameter testing methods we may be limited in the breadth ofadditional products we can offer in the future, which could impact our future revenues and profits.31We have initiated development of a new version of our HTG EdgeSeq system that will target the lower-volume throughput lab market. Thisdevelopment program, which we refer to as Project JANUS, is expected to increase our addressable market by enabling efficient molecular profiling of smallerquantity batches of samples. This program involves the development of new chemistry that is not currently compatible with our existing HTG EdgeSeqplatform. In the third quarter of 2016, we suspended the development of the Project JANUS program. If we are unable to resume or successfully develop thisnew version of our HTG EdgeSeq system and in the market window we anticipate, automation of our new chemistry could be delayed and our addressablemarket could be limited, which could harm our business, results of operations and financial condition.We may not be able to develop new products or enhance the capabilities of our systems to keep pace with rapidly changing technology and customerrequirements, which could have a material adverse effect on our business and operating results.Our success depends on our ability to develop new products and applications for our technology in existing and new markets, while improving theperformance and cost-effectiveness of our systems. New technologies, techniques or products could emerge that might offer better combinations of price andperformance than our current or future products and systems. Existing or future markets for our products, including gene expression analysis, liquid-basedspecimen analysis (e.g., plasma, blood and urine) and single-cell analysis, as well as potential markets for our diagnostic product candidates, are characterizedby rapid technological change and innovation. It is critical to our success that we anticipate changes in technology and customer requirements andsuccessfully introduce new, enhanced and competitive technologies to meet our customers’ and prospective customers’ needs on a timely and cost-effectivebasis. At the same time, however, we must carefully manage the introduction of new products. If customers believe that such products will offer enhancedfeatures or be sold for a more attractive price, they may delay purchases until such products are available. We may also have excess or obsolete inventory ofolder products as we transition to new products and our experience in managing product transitions is very limited. If we do not successfully innovate andintroduce new technology into our product lines or effectively manage the transitions to new product offerings, our revenues and results of operations will beadversely impacted.Competitors may respond more quickly and effectively than we do to new or changing opportunities, technologies, standards or customerrequirements. We anticipate that we will face increased competition in the future as existing companies and competitors develop new or improved productsand as new companies enter the market with new technologies.If we do not successfully manage the development and launch of new products, our financial results could be adversely affected.We face risks associated with launching new products and with undertaking to comply with regulatory requirements for certain of our products. If weencounter development or manufacturing challenges, adjust our product development priorities, or discover errors during our product development cycle, theproduct launch date(s) may be delayed or certain product development projects may be terminated. The expenses or losses associated with unsuccessfulproduct development or launch activities or lack of market acceptance of our new products could adversely affect our business or financial condition.If we do not achieve, sustain or successfully manage our anticipated growth, our business and growth prospects will be harmed.Our current personnel, systems and facilities may not be adequate to support our business plan and future growth. Our need to effectively manage ouroperations, growth and various projects requires that we, among other things: •continue to improve our operational, financial, management and regulatory compliance controls and reporting systems and procedures; •attract and retain sufficient numbers of talented employees; •manage our commercialization activities effectively and in a cost-effective manner; •manage our relationship with third parties related to the commercialization of our products; and •manage our development efforts effectively while carrying out our contractual obligations to contractors and other third parties.Moreover, growth will place significant strains on our management and our operational and financial systems and processes. For example, expandedmarket penetration of our HTG EdgeSeq system and related proprietary panels, and future development and approval of diagnostic products, are key elementsof our growth strategy that will require us to hire and retain additional sales and marketing, regulatory, manufacturing and quality assurance personnel. If wedo not successfully forecast the timing and cost of the development of new panels and diagnostic products, the regulatory clearance or approval for productmarketing of any future diagnostic products or the demand and commercialization costs of such products, or manage our anticipated expenses accordingly,our operating results will be harmed.32Our future success is dependent upon our ability to expand our customer base and introduce new applications.Our current customer base is primarily composed of biopharmaceutical companies (including those contracted by QML pursuant to our GoverningAgreement), academic institutions and molecular labs that perform analyses using or directly or indirectly obtain services based on our HTG EdgeSeq systemand consumables for research use only, which means that the products or data from services may not be used for clinical diagnostic purposes. In July 2016, weobtained CE marking in Europe for our HTG EdgeSeq system and HTG EdgeSeq DLBCL Cell of Origin Assay EU. In March 2017, we obtained CE markingin Europe for our HTG EdgeSeq ALKPlus Assay EU. These products may now be used by customers for diagnostic purposes in Europe. Currently, we do notintend to and, where applicable, do not have appropriate licenses or permits to conduct diagnostic testing services. Our success will depend, in part, upon ourability to increase our market penetration among our customer bases and to expand our market by developing and marketing new clinical diagnostic testsand RUO applications (whether product or service), and to introduce diagnostic products into clinical laboratories in the United States and other jurisdictionsafter obtaining the requisite regulatory clearances or approvals. We may not be able to successfully complete development of or commercialize any of ourplanned future tests and applications. To achieve these goals, we will need to conduct substantial research and development, conduct clinical validationstudies, expend significant funds, expand and scale-up our research, development, service and manufacturing processes and facilities, expand the number ofprojects under our Governing Agreement, expand and train our sales force; and seek and obtain regulatory clearance or approvals of our new tests andapplications, as required by applicable regulations. Additionally, we must demonstrate to laboratory directors, physicians and third-party payors that ourcurrent and any future diagnostic products are effective in obtaining clinically relevant information that can inform treatment decisions, and that our HTGEdgeSeq system and related panels can enable an equivalent or superior approach than other available technology. Furthermore, we expect that acombination of increasing the installed base of our HTG EdgeSeq systems, expanding the number of projects under our Governing Agreement, and enteringinto additional service and custom RUO assay development agreements with biopharmaceutical customers will drive increased demand for our relativelyhigh margin panels. If we are not able to successfully increase our installed base and biopharmaceutical customer relationships, then sales of our products andservices, and our margins for these revenue items may not meet expectations. Attracting new customers and introducing new products and services requiressubstantial time and expense. Any failure to expand our existing customer base, or launch new products, including diagnostic products or services, wouldadversely affect our ability to improve our operating results.Our financial results may vary significantly from quarter to quarter or may fall below the expectations of investors or securities analysts, each of whichmay adversely affect our stock price.Investors should consider our business and prospects considering the risks and difficulties we expect to encounter in the new, uncertain and rapidlyevolving markets in which we compete. Because these markets are new and evolving, predicting their future growth and size is difficult. We expect that ourvisibility into future sales of our products, including volumes, prices and product mix between instruments, consumables and services, will continue to belimited and could result in unexpected fluctuations in our quarterly and annual operating results.Numerous other factors, many of which are outside our control, may cause or contribute to significant fluctuations in our quarterly and annualoperating results. For example, QML and another customer accounted for 54% and 8% of our revenue, respectively, for the year ended December 31, 2017,and QML and another customer accounted for 66% and 11% of our accounts receivable balance, respectively, as of December 31, 2017. If orders from our topcustomers or the number of collaboration projects with QML are reduced or discontinued, our revenue in future periods may materially decrease. Fluctuationsin our operating results may make financial planning and forecasting difficult. In addition, these fluctuations may result in unanticipated decreases in ouravailable cash, which could negatively affect our business and prospects. Factors that may contribute to fluctuations in our operating results include many ofthe risks described under the caption “Risk Factors – Risks Related to Our Business and Strategy” of this report. In addition, one or more of such factors maycause our revenue or operating expenses in one period to be disproportionately higher or lower relative to the others. Our products involve a significantcapital commitment from our customers or may depend on customer studies that have variable or indefinite timelines and accordingly, involve a lengthysales cycle. We may expend significant effort in attempting to make a particular sale, which may be deferred by the customer or never occur. Also, activitiesperformed under our Governing Agreement involve significant resource commitments by us and depend on QML activities over which we have limitedcontrol and on biopharmaceutical customer activities and studies that have variable or indefinite timelines and outcomes. We may expend significant effortin attempting to meet our development obligations under the Governing Agreement, the respective payments for which may occur in a different period.Accordingly, comparing our operating results on a period-to-period basis may not be meaningful, and investors should not rely on our past results as anindication of our future performance. If such fluctuations occur or if our operating results deviate from our expectations or the expectations of investors orsecurities analysts, our stock price may be adversely affected.Our sales cycle is lengthy and variable, which makes it difficult for us to forecast revenue and other operating results.Our sales process involves numerous interactions with multiple individuals within any given organization, and often includes in-depth analysis bypotential customers of our products (where in some instances we will provide a demonstration unit for their use and evaluation), performance of proof-of-principle studies, preparation of extensive documentation and a lengthy review process. As a result of these factors, the capital investment required inpurchasing our instruments and the budget cycles of our customers, the time33from initial contact with a customer to our receipt of a purchase order can vary significantly and be up to 12 months or longer. Given the length anduncertainty of our sales cycle, we have in the past experienced, and likely will in the future experience, fluctuations in our product and product-relatedservices revenue on a period-to-period basis. In addition, any failure to meet customer expectations could result in customers choosing to retain their existingsystems or service providers or to purchase systems or services other than ours. The revenue that we expect to earn from our collaborative developmentservices are also subject to an extended, variable timeline based on each project agreement, which will likely result in fluctuations in our collaborativedevelopment services revenue on a period-to-period basis as well.If the utility of our HTG EdgeSeq system, proprietary profiling panels, services and solutions in development is not supported by studies published in peer-reviewed medical publications, the rate of adoption of our current and future products and the rate of reimbursement of our future products by third-partypayors may be negatively affected.We anticipate that we will need to maintain a continuing presence in peer-reviewed publications to promote adoption of our products bybiopharmaceutical companies, academic institutions and molecular labs and to promote favorable coverage and reimbursement decisions. We believe thatpeer-reviewed journal articles that provide evidence of the utility of our current and future products or the technology underlying the HTG EdgeSeq system,consumables and services are important to our commercial success. It is critical to the success of our sales efforts that we educate a sufficient number ofclinicians and administrators about our HTG EdgeSeq system, our current panels and services and our future solutions, and demonstrate the research andclinical benefits of these solutions. Our customers may not adopt our current and future solutions, and third-party payors may not cover or adequatelyreimburse our future products, unless they determine, based on published peer-reviewed journal articles and the experience of other researchers andclinicians, that our products provide accurate, reliable, useful and cost-effective information. Peer-reviewed publications regarding our products andsolutions may be limited by many factors, including delays in the completion of, poor design of, or lack of compelling data from studies that would be thesubject of the article. If our current and future product and product-related service solutions or the technology underlying such products and services do notreceive sufficient favorable exposure in peer-reviewed publications, the rate of research and clinician adoption and positive coverage and reimbursementdecisions could be negatively affected.We provide our HTG EdgeSeq system and profiling panels free of charge or through other arrangements to customers or key opinion leaders throughevaluation agreements or reagent rental programs, and these programs may not be successful in generating recurring revenue from sales of our systemsand proprietary panels.We sell our HTG EdgeSeq system and profiling panels under different arrangements to expand our installed base and facilitate the adoption of ourplatform.In some instances, we provide equipment free of charge under evaluation agreements for a limited period of time to permit the user to evaluate thesystem for their purposes in anticipation of a decision to purchase the system. We retain title to the equipment under such arrangements unless the evaluatorpurchases the equipment, and in most cases, require evaluation customers to purchase a minimum quantity of consumables during the evaluation period.When we place a system under a reagent rental agreement, we install equipment in the customer’s facility without a fee and the customer agrees topurchase consumable products at a stated priced over the term of the agreement. While some of these agreements did not historically contain a minimumpurchase requirement, we have included a minimum purchase requirement in all current reagent rental agreements, and will continue to do so in the future.We retain title to the equipment and such title is transferred to the customer at no additional charge at the end of the initial arrangement. The cost of theinstrument under the agreement is expected to be recovered in the fees charged for consumables, to the extent sold, over the term of the agreement.Other arrangements might include a research agreement whereby an academic collaborator agrees to provide biological samples in exchange for theuse of an HTG EdgeSeq system at no cost in furtherance of the collaborator’s professional goals and/or the educational or research objectives of an applicableinstitution.Any of the foregoing arrangements could result in lost revenues and profit and potentially harm our long-term goal of achieving profitable operations.In addition, despite the fact we require customers who receive systems we continue to own to carry insurance sufficient to protect us against any equipmentlosses, we cannot guarantee that they will maintain such coverage, which may expose us to a loss of the value of the equipment in the event of any loss ordamage.There are instances where we provide our systems to key opinion leaders free of charge, to gather data and publish the results of their research to assistour marketing efforts. We have no control over some of the work being performed by these key opinion leaders, or whether the results will be satisfactory. It ispossible that the key opinion leader may generate data that is unsatisfactory and could potentially harm our marketing efforts. In addition, customers mayfrom time to time create negative publicity about their experience with our systems, which could harm our reputation and negatively affect market perceptionand adoption of our platform.34Placing our HTG EdgeSeq systems under evaluation agreements, under reagent rental agreements or with our key opinion leaders without receivingpayment for the instruments could require substantial additional working capital to provide additional units for sale to our customers.Our strategy of developing companion diagnostic products may require large investments in working capital and may not generate any revenues.A key component of our strategy is the development of companion diagnostic products designed to determine the appropriate patient population foradministration of a particular therapeutic to more successfully treat a variety of illnesses. We have an exclusive arrangement with QML to develop certaincompanion diagnostic products for biopharmaceutical companies under our Governing Agreement. Otherwise, we may choose to independently developcompanion diagnostic products with or without a biopharmaceutical partner. Successfully developing a companion diagnostic product depends both onregulatory approval for administration of the therapeutic, as well as regulatory approval of the diagnostic product. Even if we are successful in developingproducts that would be useful as companion diagnostic products, and potentially receive regulatory approval for such products, the biopharmaceuticalcompanies that develop the corresponding therapeutics may ultimately be unsuccessful in obtaining regulatory approval for any such therapeutic, or, even ifsuccessful, select a competing technology to use in their regulatory submission instead of ours. The development, especially the independent development,of companion diagnostic products requires a significant investment of working capital which may not result in any future income. This could require us toraise additional funds which could dilute our current investors, or could impact our ability to continue our operations in the future.Our current business depends on levels of research and development spending by academic and governmental research institutions and biopharmaceuticalcompanies, a reduction in which could limit demand for our products and adversely affect our business and operating results.Our revenue is currently derived from sales of our HTG EdgeSeq system and related proprietary panels, the development of custom RUO assays andsample processing for research applications to biopharmaceutical companies, academic institutions and molecular labs, predominantly in the United Statesand Europe, and collaborative development services. The demand for our products and services will depend in part upon the research and developmentbudgets of these customers, which are impacted by factors beyond our control, such as: •changes in government programs that provide funding to research institutions and companies; •macroeconomic conditions and the political climate; •changes in the regulatory environment; •differences in budgetary cycles; •market-driven pressures to consolidate operations and reduce costs; and •market acceptance of relatively new technologies, such as ours.We believe that any uncertainty regarding the availability of research funding may adversely affect our operating results and may adversely affectsales to customers or potential customers that rely on government funding. In addition, academic, governmental and other research institutions that fundresearch and development activities may be subject to stringent budgetary constraints that could result in spending reductions, reduced allocations or budgetcutbacks, which could jeopardize the ability of these customers to purchase our products or services. Our operating results may fluctuate substantially due toreductions and delays in research and development expenditures by these customers. Any decrease in our customers’ budgets or expenditures, or in the size,scope or frequency of capital or operating expenditures, could materially and adversely affect our business, operating results and financial condition.As part of our current business model, we intend to seek to enter into strategic development collaborations and licensing arrangements with third partiesto develop diagnostic tests.We have relied, and expect to continue to rely, on strategic development collaborations and licensing agreements with third parties to develop or in-license technologies based on which products or services we may develop or offer. We have entered into agreements with third parties to facilitate or enableour development of assays, and ultimately diagnostic tests, to aid in the diagnosis of oncology diseases, such as breast cancer and melanoma, and otherdiseases. We intend to enter into additional similar agreements with life sciences companies, biopharmaceutical companies and other researchers for futurediagnostic products. However, we cannot guarantee that we will enter into any additional agreements. In particular, our life sciences research orbiopharmaceutical customers are not obligated to collaborate with us or license technology to us, and they may choose to develop diagnostic productsthemselves or collaborate with our competitors. Establishing development collaborations and licensing arrangements is difficult and time-35consuming. Discussions may not lead to development collaborations or licenses on favorable terms, or at all. Potential collaborators or licensors may electnot to work with us based upon their assessment of our financial, regulatory or intellectual property position. To the extent that we enter new collaborativedevelopment or licensing agreements, they may never result in the successful development or commercialization of future tests or other products for a varietyof reasons, including because our collaborators may not succeed in performing their obligations or may choose not to cooperate with us. We cannot controlthe amount and timing of our collaborators’ resources that will be devoted to performing their responsibilities under our agreements with them. Moreover, tothe extent we agree to work exclusively with a party in a given area, our opportunities to collaborate with others would be limited. Even if we establish newrelationships, they may never result in the successful development or commercialization of future tests or other products. Disputes with our collaboratorscould also impair our reputation or result in development delays, decreased revenues and litigation expenses.Our research and development efforts will be hindered if we are not able to contract with third parties for access to archival patient samples.Our future development of products for clinical indications will require access to archival patient samples for which data relevant to the clinicalindication of interest is known. We rely on our ability to secure access to these archived patient samples, including FFPE tissue, plasma, serum, whole bloodpreserved in PAX-gene, or various cytology preparations, together with the information pertaining to the clinical outcomes of the patients from which thesamples were taken. Owners or custodians of relevant samples may be difficult to identify and/or identified samples may be of poor quality or limited innumber or amount. Additionally, others compete with us for access to these samples for both research and commercial purposes. Even when an appropriatecohort of samples is identified, the process of negotiating access to these samples can be lengthy because it typically involves numerous parties and approvallevels to resolve complex issues such as usage rights, institutional review board approval, privacy rights, publication rights, and intellectual propertyownership. In addition, in some instances the cost to acquire samples can be prohibitively expensive. If we are not able to negotiate access to archived patientsamples on a timely basis and on acceptable terms, or at all, or if our competitors or others secure access to these samples before us, our ability to research,develop and commercialize future products will be limited or delayed.The life sciences research and diagnostic markets are highly competitive. We face competition from enhanced or alternative technologies and products,which could render our products and/or technologies obsolete. If we fail to compete effectively, our business and operating results will suffer.We face significant competition in the life sciences research and diagnostics markets. We currently compete with both established and early-stage lifesciences research companies that design, manufacture and market instruments and consumables for gene expression analysis, liquid-based specimen analysis(e.g., plasma, blood and urine), single-cell analysis, PCR, digital PCR, other nucleic acid detection and additional applications. These companies use well-established laboratory techniques such as microarrays or qPCR as well as newer technologies such as next generation sequencing. We believe our principalcompetitors in the life sciences research market are Agilent Technologies, Inc., ArcherDx, Inc., BioRad Laboratories, Fluidigm Corporation, FoundationMedicine, Inc., Genomic Health, Illumina, Inc., Abbott Molecular, Luminex Corporation, Affymetrix, Inc., NanoString Technologies, Inc., entities owned andcontrolled by QIAGEN N.V., Roche Diagnostics, a division of the Roche Group of companies, and Thermo Fisher Scientific, Inc. In addition, there are severalother market entrants in the process of developing novel technologies for the life sciences market. One or more of our competitors could develop a productthat is superior to a product we offer or intend to offer or our technology and products may be rendered obsolete or uneconomical by advances in existingtechnologies.Within the diagnostic market, there are competitors that manufacture systems for sales to hospitals and laboratories and other competitors that offertests conducted through CLIA laboratories. We will also compete with commercial diagnostics companies. Most of our current competitors are either publiclytraded, or are divisions of publicly traded companies, and enjoy a number of competitive advantages over us, including: •greater name and brand recognition, financial and human resources; •broader product lines; •larger sales forces and more established distributor networks; •substantial intellectual property portfolios; •larger and more established customer bases and relationships; and •better established, larger scale, and lower cost manufacturing capabilities.36We believe that the principal competitive factors in all of our target markets include: •cost of capital equipment; •cost of consumables and supplies; •reputation among customers; •innovation in product offerings; •flexibility and ease-of-use; •accuracy and reproducibility of results; and •compatibility with existing laboratory processes, tools and methods.We believe that additional competitive factors specific to the diagnostics market include: •breadth of clinical decisions that can be influenced by information generated by tests; •volume, quality, and strength of clinical and analytical validation data; •availability of coverage and adequate reimbursement for testing services; and •economic benefit accrued to customers based on testing services enabled by products.Our products may not compete favorably and we may not be successful in the face of increasing competition from new products and technologiesintroduced by our existing competitors or new companies entering our markets. In addition, our competitors may have or may develop products ortechnologies that currently or in the future will enable them to produce competitive products with greater capabilities or at lower costs than ours. Any failureto compete effectively could materially and adversely affect our business, financial condition and operating results.We are dependent on a single third-party supplier for a certain subcomponent of our systems and the loss of this supplier could harm our business.We currently rely on a single supplier to supply a subcomponent used in our HTG EdgeSeq processors. While we periodically forecast our needs forthis subcomponent, our contract with this supplier, which may be a standard purchase order, does not commit them to carry inventory or make available anyparticular quantities, and the supplier may give other customers’ needs higher priority than ours and we may not be able to obtain adequate supplies in atimely manner or on commercially reasonable terms. If we were to lose this supplier, we may not be able to identify or enter into agreements with alternativesuppliers on a timely basis on acceptable terms, or at all. If we should encounter delays or difficulties in securing the quality and quantity of subcomponentwe require for our processors, our supply chain would be interrupted which would adversely affect our sales. A loss of this supplier could significantly delaythe delivery of our HTG EdgeSeq processor, which in turn would materially affect our ability to generate revenue. If any of these events occur, our businessand operating results could be materially harmed.We may encounter manufacturing difficulties that could impede or delay production of our HTG EdgeSeq systems.We began manufacturing our HTG EdgeSeq system internally in 2016. We have limited experience with manufacturing the system and our internalmanufacturing operations may encounter difficulties involving, among other things, scale-up of manufacturing processes, production efficiency and output,regulatory compliance, quality control and quality assurance, and shortages of qualified personnel. Any failure in our planned internal manufacturingoperations could cause us to be unable to meet demand for these systems, delay the delivery of the system to customers, and harm our business relationshipsand reputation.If we encounter difficulties in our planned internal manufacturing operations, we may need to engage a third-party supplier, provided we cannot besure we will be able to do so in a timely manner, or at all, or on favorable terms.Any of these factors could cause us to delay or suspend production of our HTG EdgeSeq system, entail unplanned additional costs and materiallyharm our business, results of operations and financial condition.If our Tucson facilities become unavailable or inoperable, the manufacturing of our instrument and consumable products or our ability to process salesorders will be interrupted and our business could be materially harmed.We manufacture our consumable products and our HTG EdgeSeq system and perform our RUO profiling and collaborative development services inour Tucson, Arizona facilities. In addition, our Tucson facilities are the center for order processing, receipt of37critical components of our HTG EdgeSeq instrument and shipping products to customers. We do not have redundant facilities. Damage or the inability toutilize our Tucson facilities and the equipment we use to perform research, development or services and manufacture our products could be costly, and wewould require substantial lead-time to repair or replace this facility and equipment. The Tucson facilities may be harmed or rendered inoperable by natural orman-made disasters, including flooding, wind damage, power spikes and power outages, which may render it difficult or impossible for us to perform thesecritical functions for some period of time. The inability to manufacture consumables or instruments, process customer samples, perform development servicesunder our Governing Agreement or ship products to customers for even a short period of time may result in the loss of customers or harm our reputation, andwe may be unable to regain those customers in the future. Although we possess insurance for damage to our property and the disruption of our business, thisinsurance may not be sufficient to cover all of our potential losses and may not continue to be available to us on acceptable terms, or at all.We expect to generate a portion of our revenue internationally and are subject to various risks relating to our international activities which couldadversely affect our operating results.During the year ended December 31, 2017, approximately 67% of our revenue was generated from our Governing Agreement with QML, who islocated outside of the United States, compared with 16% for the year ended December 31, 2016. We expect that a percentage of our future revenue willcontinue to come from international sources, driven in part by activities conducted pursuant to our Governing Agreement, and we expect to expand ouroverseas operations and develop opportunities in additional areas. Engaging in international business involves a number of difficulties and risks, including: •required compliance with existing and changing foreign regulatory requirements and laws; •required compliance with anti-bribery laws, such as the U.S. Foreign Corrupt Practices Act and U.K. Bribery Act, data privacy requirements,labor laws and anti-competition regulations; •export and import restrictions; •various reimbursement, pricing and insurance regimes; •laws and business practices favoring local companies; •longer payment cycles and difficulties in enforcing agreements and collecting receivables through certain foreign legal systems; •political and economic instability; •potentially adverse tax consequences, tariffs, customs charges, bureaucratic requirements and other trade barriers, including transfer pricing,value added and other tax systems, double taxation and restrictions and/or taxation on repatriation of earnings; •tariffs, customs charges, bureaucratic requirements and other trade barriers; •difficulties and costs of staffing and managing foreign operations, including difficulties and costs associated with foreign employment laws; •increased financial accounting and reporting burdens and complexities; and •difficulties protecting, procuring, or enforcing intellectual property rights, including from reduced or varied protection for intellectual propertyrights in some countries.As we expand internationally our results of operations and cash flows will become increasingly subject to fluctuations due to changes in foreigncurrency exchange rates. Historically, most of our revenue has been denominated in U.S. dollars, although we have sold our products and services in localcurrency outside of the United States, principally the Euro. Our expenses are generally denominated in the currencies in which our operations are located,which is primarily in the United States. As our operations in countries outside of the United States grows, our results of operations and cash flows willincreasingly be subject to fluctuations due to changes in foreign currency exchange rates, which could negatively impact our results of operations in thefuture. For example, if the value of the U.S. dollar increases relative to foreign currencies, in the absence of an offsetting change in local currency prices, ourrevenue could be adversely affected as we convert revenue from local currencies to U.S. dollars.If we dedicate significant resources to our international operations and are unable to manage these risks effectively, our business, operating results andprospects will suffer. Moreover, we cannot be certain that the investment and additional resources required in establishing operations in other countries willproduce desired levels of revenue or profitability.In addition, any failure to comply with applicable legal and regulatory obligations could negatively impact us in a variety of ways that include, butare not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of exportprivileges, seizure of shipments and restrictions on certain business activities.38We rely on distributors for sales of our products in several markets outside of the United States.We have established exclusive and non-exclusive distribution agreements for our HTG EdgeSeq platform and related profiling panels within parts ofEurope and the Middle East. We intend to continue to grow our business internationally, and to do so, in addition to expanding our own direct sales andsupport team, we plan to attract additional distributors and sales partners to maximize the commercial opportunity for our products. We cannot guarantee thatwe will be successful in attracting desirable distribution and sales partners or that we will be able to enter into such arrangements on favorable terms.Distributors and sales partners may not commit the necessary resources to market and sell our products to the level of our expectations or may favormarketing the products of our competitors. If current or future distributors or sales partners do not perform adequately, or we are unable to enter into effectivearrangements with distributors or sales partners in particular geographic areas, we may not realize long-term international revenue growth.Limitations in the use of our products could harm our reputation or decrease market acceptance of our products; undetected errors or defects in ourproducts could harm our reputation, decrease market acceptance of our products or expose us to product liability claims.Our products are subject to the limitations set forth in the product labeling, which may not satisfy the needs of all customers. For example, in the pastwe have introduced new panels that initially were intended to be used with specific sample types. Because our customers desire that our panels be broadlyapplicable to many biological sample types, these initial limitations could harm our reputation or decrease market acceptance of our products. If that occurs,we may incur significant costs, the attention of our key personnel could be diverted, or other significant customer relations problems may arise, which couldharm our business and operating results.Similarly, our products may contain undetected errors or defects when first introduced or as new versions are released. Since our current customers useour products for research and if cleared or approved for diagnostic applications, disruptions or other performance problems with our products may damage ourcustomers’ businesses and could harm our reputation. If that occurs, we may incur significant costs, the attention of our key personnel could be diverted, orother significant customer relations problems may arise. We may also be subject to warranty and liability claims for damages related to errors or defects in ourproducts. A material liability claim or other occurrence that harms our reputation or decreases market acceptance of our products could harm our business andoperating results.The sale and use of products or services based on our technologies, or activities related to our research and clinical studies, could lead to the filing ofproduct liability claims if someone were to allege that one of our products contained a design or manufacturing defect which resulted in the failure toadequately perform the analysis for which it was designed. A product liability claim could result in substantial damages and be costly and time consuming todefend, either of which could materially harm our business or financial condition. We cannot assure investors that our product liability insurance couldadequately protect our assets from the financial impact of defending a product liability claim. Any product liability claim brought against us, with or withoutmerit, could increase our product liability insurance rates or prevent us from securing insurance coverage in the future.We may need to raise additional capital to fund our operations in the future. If we are unsuccessful in attracting new capital, we may not be able tocontinue operations or may be forced to sell assets to do so. Alternatively, capital may not be available to us on favorable terms, or if at all. If available,financing terms may lead to significant dilution of our stockholders’ equity.We are not profitable and have had negative cash flow from operations since our inception. To fund our operations and develop and commercializeour products, we have relied primarily on equity and debt financings and revenue generated from the sale of our HTG EdgeSeq systems, proprietaryconsumables, related services and collaborative arrangements with biopharmaceutical company customers. We currently anticipate that our cash and cashequivalents, including funds generated in our January 2018 public offering, will be sufficient to enable us to fund our operations for at least the next 12months. We may need to obtain additional funds or refinance our existing Growth Term Loan to finance our operations in the future if our estimates of theamount of cash necessary to fund our operations and development and commercialization activities prove to be wrong, and we could spend our availablefinancial resources much faster than we currently expect. Additional capital may not be available at such times or amounts as needed by us. Even if capital isavailable, it might be available only on unfavorable terms. Any additional equity or convertible debt financing into which we enter could be dilutive to ourexisting stockholders. Any future debt financing into which we enter may impose covenants upon us that restrict our operations, including limitations on ourability to incur liens or additional debt, pay dividends, repurchase our stock, make certain investments and engage in certain merger, consolidation or assetsale transactions. Any debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders. If we raiseadditional funds through collaboration and licensing arrangements with third parties, we may need to relinquish rights to our technologies or our products, orgrant licenses on terms that are not favorable to us. If access to sufficient capital is not available as and when needed, our business will be materially impairedand we may be required to cease operations, curtail one or more product development or commercialization programs, or significantly reduce expenses, sellassets, seek a merger or joint venture partner, file for protection from creditors or liquidate all of our assets. Any of these factors could harm our operatingresults.39Payments under the instruments governing our indebtedness may reduce our working capital. In addition, a default under our term loan agreement couldcause a material adverse effect on our financial position.In August 2014, we entered into a $16.0 million Growth Term Loan agreement with Oxford Finance LLC and Silicon Valley Bank, who wecollectively refer to as our senior lenders. Under the terms of the Growth Term Loan, the senior lenders initially provided us with a term loan of $11.0 million.In March 2016, we borrowed the remaining $5.0 million pursuant to the term loan agreement. The loan is secured by a lien covering substantially all of ourassets, excluding patents, trademarks and other intellectual property rights (except for rights to payments related to the sale, licensing or disposition of suchintellectual property rights) and certain other specified property. The interest-only payment period expired in April 2016, and we are currently required tomake monthly principal and interest payments through September 2018. As of December 31, 2017, we had $5.8 million outstanding under the Growth TermLoan, all of which is scheduled to become due and payable over the nine months following such date. Payments under the Growth Term Loan will result in areduction in our working capital. If we default under the Growth Term Loan, our senior lenders could foreclose on our assets, including substantially all ofour cash, which is held in accounts with our senior lenders.Pursuant to the terms of an asset purchase agreement with NuvoGen, we agreed to annually pay NuvoGen the greater of $400,000 or 6% of our yearlyrevenue until the total aggregate cash compensation paid to NuvoGen under the agreement equals $15.0 million. To date, we have paid NuvoGenapproximately $7.0 million. Payments to NuvoGen will result in a reduction in our working capital as we continue to make payments on this obligation.Pursuant to the terms of the $3.0 million QNAH Convertible Note that we issued in October 2017, we will be required to repay the entire outstandingprincipal amount of the note and unpaid accrued interest thereon in October 2020, subject to the terms of a subordination agreement between QNAH and oursenior lenders, provided QNAH may, at its election, convert all or any portion of the outstanding principal balance of the note and unpaid accrued interest atany time prior to the maturity date into shares of our common stock at a conversion price of $3.984 per share. Repayment of this note and unpaid accruedinterest thereon at maturity would result in a reduction in our working capital, which could be significant depending on our cash position on the maturitydate.The Growth Term Loan agreement requires us, and any debt arrangements we may enter into in the future may require us, to comply with variouscovenants that limit our ability to, among other things: •dispose of assets; •complete mergers or acquisitions; •incur indebtedness; •encumber assets; •pay dividends or make other distributions to holders of our capital stock; •make specified investments; •change certain key management personnel; and •engage in transactions with our affiliates.These restrictions could inhibit our ability to pursue our business strategies. If we default under our obligations under the Growth Term Loan, thesenior lenders could proceed against the collateral granted to them to secure our indebtedness or declare all obligation under the Growth Term Loan to be dueand payable. In certain circumstances, procedures by the senior lenders could result in a loss by us of all of our equipment and inventory, which are includedin the collateral granted to the senior lenders. In addition, upon any distribution of assets pursuant to any liquidation, insolvency, dissolution, reorganizationor similar proceeding, the holders of secured indebtedness will be entitled to receive payment in full from the proceeds of the collateral securing our securedindebtedness before the holders of other indebtedness or our common stock will be entitled to receive any distribution with respect thereto.We may incur additional indebtedness in the future. The debt instruments governing such indebtedness may contain provisions that are as, or more,restrictive than the provisions governing our existing indebtedness under the Growth Term Loan.The enactment of U.S. tax reform in 2017 resulted in changes in the U.S. taxation of domestic and international business activities which could materiallyimpact our future financial position and results of operations.The 2017 Tax Act, which was signed into law on December 22, 2017, significantly revises the Internal Revenue Code of 1986, as amended (the“IRC”). The newly enacted federal income tax law, among other things, contains significant changes to corporate taxation, including a reduction of thefederal statutory rates from a top marginal rate of 35% to a flat rate of 21%, limitation of the tax deduction for interest expense to 30% of adjusted earnings(except for certain small businesses), limitation of the deduction for net operating losses to 80% of current year taxable income, elimination of net operatingloss carrybacks, one time taxation of offshore earnings at reduced rates regardless of whether they are repatriated, elimination of U.S. tax on foreign earnings(subject to certain40important exceptions), immediate deductions for certain new investments instead of deductions for depreciation expense over time, and modifying orrepealing many business deductions and credits. Notwithstanding the reduction in the corporate income tax rate, the overall impact of the new federal tax lawis uncertain and our business and financial condition could be adversely affected. It is also unknown if and to what extent various states will conform to thenewly enacted federal tax law. The impact of this tax reform on holders of our common stock is likewise uncertain and could be adverse. We urge you toconsult with a legal and/or tax advisor with respect to this legislation and the potential consequences of investing in our common stock.Our ability to use net operating losses to offset future taxable income may be subject to certain limitations.As of December 31, 2017, we had federal net operating loss carryforwards (“NOLs”) to offset future taxable income of approximately $122.0 million,which will begin to expire in 2021 if not utilized. A lack of future taxable income would adversely affect our ability to utilize these NOLs. In addition, underSection 382 of the IRC, a corporation that undergoes an “ownership change” (generally defined as a greater than 50% change, by value, in its equityownership over a three-year period) is subject to limitations on its ability to utilize its NOLs to offset future taxable income. We believe we may have alreadyexperienced one or more ownership changes and may in the future experience one or more additional ownership changes, and thus, our ability to utilize pre-ownership change NOLs and other pre-ownership change tax attributes to offset post-ownership change income may be limited. Such limitations may cause aportion of our NOL and credit carryforwards to expire. In addition, future changes in our stock ownership, including as a result of future financings, as well aschanges that may be outside of our control, could result in ownership changes under Section 382 of the Code. Our NOLs may also be impaired under similarprovisions of state law. We have recorded a full valuation allowance related to our NOLs and other deferred tax assets due to the uncertainty of the ultimaterealization of the future benefits of those assets.Acquisitions or joint ventures could disrupt our business, cause dilution to our stockholders and otherwise harm our business.We may acquire other businesses, products or technologies as well as pursue strategic alliances, joint ventures, technology licenses or investments incomplementary businesses. We have limited experience with respect to business, product or technology acquisitions or the formation of collaborations,strategic alliances and joint ventures or investing in complementary businesses. Any of these transactions could be material to our financial condition andoperating results and expose us to many risks, including: •disruption in our relationships with customers, distributors or suppliers as a result of such a transaction; •unanticipated liabilities related to acquired companies; •difficulties integrating acquired personnel, technologies and operations into our existing business; •diversion of management time and focus from operating our business to acquisition integration challenges; •increases in our expenses and reductions in our cash available for operations and other uses; and •possible write-offs or impairment charges relating to acquired businesses.Foreign acquisitions involve unique risks in addition to those mentioned above, including those related to integration of operations across differentcultures and languages, currency risks and the particular economic, political and regulatory risks associated with specific countries. Also, the anticipatedbenefit of any acquisition may not materialize. Future acquisitions or dispositions could result in potentially dilutive issuances of our equity securities, theincurrence of debt, contingent liabilities or amortization expenses or write-offs of goodwill, any of which could harm our financial condition. We cannotpredict the number, timing or size of future joint ventures or acquisitions, or the effect that any such transactions might have on our operating results.If any members of our management team were to leave us or we are unable to recruit, train and retain key personnel, we may not achieve our goals.Our future success depends on our ability to recruit, train, retain and motivate key personnel, including our senior management, research anddevelopment, manufacturing, service and sales and marketing personnel. If we were to lose one or more of our key employees, we may experience difficultiesin competing effectively, developing our technologies and implementing our business strategies. Competition for qualified personnel is intense, and we maynot be able to attract talent. Our growth depends, in part, on attracting, retaining and motivating highly trained sales personnel with the necessary scientificbackground and ability to understand our systems at a technical level to effectively identify and sell to potential new customers, including newbiopharmaceutical company customers. In particular, the commercialization of our HTG EdgeSeq system and related panels requires us to continue toestablish and maintain a sales and support team to optimize the market for research tools, then to fully optimize a broad array of diagnostic marketopportunities if we receive approval for any future diagnostic products. We do not maintain fixed term employment contracts or, except for our ChiefExecutive Officer, key man life insurance with any of our employees. Because of the complex and technical nature of our products and the dynamic market inwhich we compete, any failure to retain our management team or to attract, train, retain and motivate other qualified personnel could materially harm ouroperating results and growth prospects.41Our operating results may be harmed if we are required to collect sales, services or other related taxes for our products and services in jurisdictions wherewe have not historically done so.We do not believe that we are required to collect sales, use, services or other similar taxes from our customers in certain jurisdictions. However, one ormore countries or states may seek to impose sales, use, services, or other tax collection obligations on us, including for past sales. A successful assertion byone or more jurisdictions that we should collect sales or other taxes on the sale of our products and services could result in substantial tax liabilities for pastsales and decrease our ability to compete for future sales. Each country and each state has different rules and regulations governing sales and use taxes andthese rules and regulations are subject to varying interpretations that may change over time. We review these rules and regulations periodically and, when webelieve sales and use taxes apply in a particular jurisdiction, voluntarily engage tax authorities in order to determine how to comply with their rules andregulations. We cannot assure you that we will not be subject to sales and use taxes or related penalties for past sales in jurisdictions where we presentlybelieve sales and use taxes are not due.Providers of goods or services are typically held responsible by taxing authorities for the collection and payment of any applicable sales and similartaxes. If one or more taxing authorities determines that taxes should have, but have not, been paid with respect to our products and services, we may be liablefor past taxes in addition to being required to collect sales or similar taxes in respect of our products and services going forward. Liability for past taxes mayalso include substantial interest and penalty charges. Our customer contracts provide that our customers must pay all applicable sales and similar taxes.Nevertheless, customers may be reluctant to pay back taxes and may refuse responsibility for interest or penalties associated with those taxes or we maydetermine that it would not be feasible to seek reimbursement. If we are required to collect and pay back taxes and the associated interest and penalties and ifour customers do not reimburse us for all or a portion of these amounts, we will have incurred unplanned expenses that may be substantial. Moreover,imposition of such taxes on our products and services going forward will effectively increase the cost of such products and services to our customers.Many states are also pursuing legislative expansion of the scope of goods and services that are subject to sales and similar taxes as well as thecircumstances in which a vendor of goods and services must collect such taxes. Furthermore, legislative proposals have been introduced in Congress thatwould provide states with additional authority to impose such taxes. Accordingly, it is possible that either federal or state legislative changes may require usto collect additional sales and similar taxes from our customers in the future.Our insurance policies are expensive and protect us only from some business risks, which will leave us exposed to significant uninsured liabilities.We do not carry insurance for all categories of risk that our business may encounter. Some of the policies we currently maintain include generalliability, foreign liability, employee benefits liability, property, automobile, umbrella, workers’ compensation, crime (including cybercrime), fiduciary,products liability, pollution, errors and omissions and directors’ and officers’ insurance. We do not know, however, if we will be able to maintain existinginsurance with adequate levels of coverage. Any significant uninsured liability may require us to pay substantial amounts, which would adversely affect ourcash position and results of operations.Performance issues, service interruptions or price increases by our shipping carriers could adversely affect our business and harm our reputation andability to provide our services on a timely basis.Expedited, reliable shipping is essential to our operations. We rely heavily on providers of transport services for reliable and secure point-to-pointtransport of our HTG EdgeSeq systems and consumables to our customers and, as applicable, customers’ samples to our laboratory, and for enhanced trackingof these shipments. Should a carrier encounter delivery performance issues such as loss, damage or destruction of any instrumentation, consumables orsamples, it would be costly to replace such instrumentation or consumables in a timely manner and may be difficult to replace customers’ samples lost ordamaged in shipping, and such occurrences may damage our reputation and lead to decreased demand for our products and increased cost and expense to ourbusiness. In addition, any significant increase in shipping rates could adversely affect our operating margins and results of operations. Similarly, strikes,severe weather, natural disasters or other service interruptions affecting delivery services we use would adversely affect our ability to process orders for ourproducts or receive recipient samples on a timely basis.We face risks related to handling of hazardous materials and other regulations governing environmental safety.Our operations are subject to complex and stringent environmental, health, safety and other governmental laws and regulations that both publicofficials and private individuals may seek to enforce. Our activities that are subject to these regulations include, among other things, our use of hazardousmaterials and the generation, transportation and storage of waste. We could discover that we or an acquired business is not in material compliance with theseregulations. Existing laws and regulations may also be revised or reinterpreted, or new laws and regulations may become applicable to us, whetherretroactively or prospectively, that may have a negative effect on our business and results of operations. It is also impossible to eliminate completely the riskof accidental environmental contamination or injury to individuals. In such an event, we could be liable for any damages that result, and any liability couldexceed our resources or any applicable insurance coverage we may have, which events could adversely affect our business.42Cyber security risks and the failure to maintain the confidentiality, integrity, and availability of our computer hardware, software, and internetapplications and related tools and functions could result in damage to our reputation and/or subject us to costs, fines or lawsuits.Our business requires manipulating, analyzing and storing large amounts of data. In addition, we rely on an enterprise software system to operate andmanage our business. We also maintain personally identifiable information about our employees. Our business therefore depends on the continuous,effective, reliable and secure operation of our computer hardware, software, networks, Internet servers and related infrastructure. To the extent that ourhardware and software malfunction or access to our data by internal personnel is interrupted, our business could suffer. The integrity and protection of ouremployee and company data is critical to our business and employees have a high expectation that we will adequately protect their personal information. Theregulatory environment governing information, security and privacy laws is increasingly demanding and continues to evolve. Maintaining compliance withapplicable security and privacy regulations may increase our operating costs. Although our computer and communications software are protected throughphysical and software safeguards, it is still vulnerable to natural or man-made hazards, such as fire, storm, flood, power loss, wind damage,telecommunications failures, physical or software break-ins, software viruses and similar events. These events could lead to the unauthorized access,disclosure and use of non-public information. The techniques used by criminal elements to attack computer systems are sophisticated, change frequently andmay originate from less regulated and remote areas of the world. As a result, we may not be able to address these techniques proactively or implementadequate preventative measures. If our computer systems are compromised, we could be subject to fines, damages, litigation and enforcement actions, and wecould lose trade secrets, the occurrence of which could harm our business. In addition, any sustained disruption in internet access provided by othercompanies could harm our business.Risks Related to Government Regulation and Diagnostic Product ReimbursementOur research use only products for the life sciences market could become subject to regulation as medical devices by the FDA or other regulatory agenciesin the future which could increase our costs and delay our commercialization efforts, thereby materially and adversely affecting our life sciences businessand results of operations.In the United States, our products are currently labeled and sold for research use only, and not for the diagnosis or treatment of disease, and are sold toa variety of parties, including biopharmaceutical companies, academic institutions and molecular labs. Because such products are not intended for use inclinical practice in diagnostics, and the products cannot include clinical or diagnostic claims, they are exempt from many regulatory requirements otherwiseapplicable to medical devices. In particular, while the FDA regulations require that RUO products be labeled, “For Research Use Only. Not for use indiagnostic procedures,” the regulations do not otherwise subject such products to the FDA’s pre- and post-market controls for medical devices.A significant change in the laws governing RUO products or how they are enforced may require us to change our business model in order to maintaincompliance. For instance, in November 2013 the FDA issued a guidance document entitled “Distribution of In Vitro Diagnostic Products Labeled forResearch Use Only or Investigational Use Only” (the “RUO Guidance”) which highlights the FDA’s interpretation that distribution of RUO products with anylabeling, advertising or promotion that suggests that clinical laboratories can validate the test through their own procedures and subsequently offer it forclinical diagnostic use as a laboratory developed test is in conflict with RUO status. The RUO Guidance further articulates the FDA’s position that anyassistance offered in performing clinical validation or verification, or similar specialized technical support, to clinical laboratories, conflicts with RUO status.If we engage in any activities that the FDA deems to be in conflict with the RUO status held by the products that we sell, we may be subject to immediate,severe and broad FDA enforcement action that would adversely affect our ability to continue operations. Accordingly, if the FDA finds that we aredistributing our RUO products in a manner that is inconsistent with its regulations or guidance, we may be forced to stop distribution of our RUO tests untilwe are in compliance, which would reduce our revenues, increase our costs and adversely affect our business, prospects, results of operations and financialcondition. In addition, the FDA’s proposed implementation for a new framework for the regulation of LDTs may negatively impact the LDT market andthereby reduce demand for RUO products.If the FDA requires marketing authorization of our RUO products in the future, there can be no assurance that the FDA will ultimately grant anyclearance or approval requested by us in a timely manner, or at all.Approval and/or clearance by the FDA and foreign regulatory authorities for any diagnostic tests will take significant time and require significantresearch, development and clinical study expenditures and ultimately may not succeed.Before we begin to label and market our products for use as clinical diagnostics in the United States, including as companion diagnostics, unless anexemption applies, we will be required to obtain either 510(k) clearance or PMA from the FDA. In addition, we may be required to seek FDA clearance for anychanges or modifications to our products that could significantly affect their safety or effectiveness, or would constitute a change in intended use. The 510(k)clearance processes can be expensive, time-consuming and uncertain. In addition to the time required to conduct clinical studies, if necessary, it generallytakes from four to twelve months from submission of an application to obtain 510(k) clearance; however, it may take longer and 510(k) clearance may neverbe obtained.43Even if the FDA accepts a 510(k) submission for filing, the FDA may request additional information or clinical studies during its review. Our ability to obtainadditional regulatory clearances for new products and indications may be significantly delayed or may never be obtained. In addition, we may be required toobtain PMAs for new products or product modifications. The requirements of the more rigorous PMA process could delay product introductions and increasethe costs associated with FDA compliance. As with all IVD products, the FDA reserves the right to redefine the regulatory path at the time of submission orduring the review process, and could require a more burdensome approach. Even if we were to obtain regulatory approval or clearance, it may not be for theuses we believe are important or commercially attractive, in which case we would not be permitted to market our product for those uses.A 510(k) clearance or PMA submission for any future medical device product would likely place substantial restrictions on how the device ismarketed or sold, and we will be required to continue to comply with extensive regulatory requirements, including, but not limited to QSRs, registeringmanufacturing facilities, listing the products with the FDA, and complying with labeling, marketing, complaint handling, adverse event and medical devicereporting requirements and corrections and removals. We cannot assure you that we will successfully maintain the clearances or approvals we may receive inthe future. In addition, any clearances or approvals we obtain may be revoked if any issues arise that bring into question our products’ safety or effectiveness.Any failure to maintain compliance with FDA regulatory requirements could harm our business, financial condition and results of operations.Sales of our diagnostic products outside the United States will be subject to foreign regulatory requirements governing clinical studies, vigilancereporting, marketing approval, manufacturing, product licensing, pricing and reimbursement. These regulatory requirements vary greatly from country tocountry. As a result, the time required to obtain approvals outside the United States may differ from that required to obtain FDA approval and we may not beable to obtain foreign regulatory approvals on a timely basis or at all. Approval by the FDA does not ensure approval by regulatory authorities in othercountries, and approval by one foreign regulatory authority does not ensure approval by regulatory authorities in other countries or by the FDA and foreignregulatory authorities could require additional testing. In addition, the FDA regulates exports of medical devices. Failure to comply with these regulatoryrequirements or obtain required approvals could impair our ability to commercialize our diagnostic products outside of the United States.We expect to rely on third parties to conduct any future studies of our diagnostic products that may be required by the FDA or other regulatory authorities,and those third parties may not perform satisfactorily.We do not have the ability to independently conduct the clinical studies or other studies that may be required to obtain FDA and other regulatoryclearance or approval for our diagnostic products, including the HTG EdgeSeq system and related proprietary panels. Accordingly, we expect to rely on thirdparties, such as medical institutions and clinical investigators, and providers of NGS instrumentation, to conduct such studies and/or to provide informationnecessary for our submissions to regulatory authorities. Our reliance on these third parties for clinical development activities or information will reduce ourcontrol over these activities. These third-parties may not complete activities on schedule or conduct studies in accordance with regulatory requirements orour study design. Similarly, providers of NGS instrumentation may not place the same importance on our regulatory submissions as we do. Our reliance onthird parties that we do not control will not relieve us of any applicable requirement to prepare, and ensure compliance with, the various procedures requiresunder good clinical practices, or the submission of all information required in connection with requested regulatory approvals. If these third parties do notsuccessfully carry out their contractual duties or regulatory obligations or meet expected deadlines if the third parties need to be replaced or if the quality oraccuracy of the data they obtain is compromised due to their failure to adhere to our clinical protocols or regulatory requirements or for other reasons, ourstudies may be extended, delayed, suspended or terminated, and we may not be able to obtain regulatory approval for our diagnostic products.Even if we are able to obtain regulatory approval or clearance for our diagnostic products, we will continue to be subject to ongoing and extensiveregulatory requirements, and our failure to comply with these requirements could substantially harm our business.If we receive regulatory approval or clearance for our diagnostic products, we will be subject to ongoing FDA obligations and continued regulatoryoversight and review, such as compliance with QSRs, inspections by the FDA, continued adverse event and malfunction reporting, corrections and removalsreporting, registration and listing, and promotional restrictions, and we may also be subject to additional FDA post-marketing obligations. If we are not ableto maintain regulatory compliance, we may not be permitted to market our diagnostic products and/or may be subject to fines, injunctions, and civilpenalties; recall or seizure of products; operating restrictions; and criminal prosecution. In addition, we may be subject to similar regulatory complianceactions of foreign jurisdictions.44If Medicare and other third-party payors in the United States and foreign countries do not approve coverage and adequate reimbursement for our futureclinical diagnostic tests enabled by our technology, the commercial success of our diagnostic products would be compromised.We plan to develop, obtain regulatory approval for and sell clinical diagnostics products for a number of different indications. Successfulcommercialization of our clinical diagnostic products depends, in large part, on the availability of coverage and adequate reimbursement for testing servicesusing our diagnostic products from third-party payors, including government insurance plans, managed care organizations and private insurance plans. Thereis significant uncertainty surrounding third-party coverage and reimbursement for the use of tests that incorporate new technology, such as the HTG EdgeSeqsystem and related applications and assays. Reimbursement rates have the potential to fluctuate depending on the region in which the testing is provided, thetype of facility or treatment center at which the testing is done, and the third-party payor responsible for payment. If our customers are unable to obtainpositive coverage decisions from third-party payors approving reimbursement for our tests at adequate levels, the commercial success of our products wouldbe compromised and our revenue would be significantly limited. Even if we do obtain favorable reimbursement for our tests, third-party payors may withdrawtheir coverage policies, review and adjust the rate of reimbursement, require co-payments from patients or stop paying for our tests, which would reducerevenue for testing services based on our technology and demand for our diagnostic products.The American Medical Association Current Procedural Terminology (“CPT”) Editorial Panel created new CPT codes that could be used by ourcustomers to report testing for certain large-scale multianalyte GSPs, including our diagnostic products, if approved. Effective January 1, 2015, these codesallow for uniform reporting of broad genomic testing panels using technology similar to ours. While these codes standardize reporting for these tests,coverage and payment rates for GSPs remain uncertain and we cannot guarantee that coverage and/or reimbursement for these tests will be provided in theamounts we expect, or at all. Initially, industry associations recommended that payment rates for GSPs be cross-walked to existing codes on the clinicallaboratory fee schedule. On October 27, 2014, CMS issued preliminary determinations for 29 new molecular pathology codes, including the GSPs, of gapfillrather than crosswalking as recommended by the Association for Molecular Pathology. This means that local private MACs, such as Palmetto, Novidian,Novitas and Cahaba, were instructed to determine the appropriate fee schedule amounts in the first year, and CMS calculated a national payment rate basedon the median of those local fee schedule amounts in the second year. This process may make it more difficult for our customers to obtain coverage andadequate reimbursement for testing services using our diagnostic products. We cannot assure that CMS and other third-party payors will establishreimbursement rates sufficient to cover the costs incurred by our customers in using our clinical diagnostic products, if approved. On September 22, 2017,gapfill pricing was set for three CPT codes which our customers may potentially utilize to obtain reimbursement, subject to regulatory limitations, for the useof our products. CPTs 81445 and 81450, for the assessment of 5-50 genes in solid and liquid tumors, respectively, were set at $598 and $760, respectively,and remains the same as of December 31, 2017. Additionally, CPT 81455 for the assessment of 51 or more genes in solid and liquid tumors was set at $2,920.Even if we are able to establish coverage and reimbursement codes for our clinical diagnostic products in development, we will continue to be subjectto significant pricing pressure, which could harm our business, results of operations, financial condition and prospects.Third-party payors, including managed care organizations as well as government payors such as Medicare and Medicaid, have increased their effortsto control the cost, utilization and delivery of healthcare services, which may include decreased coverage or reduced reimbursement. From time to time,Congress has considered and implemented changes to the Medicare fee schedules in conjunction with budgetary legislation, and pricing and payment terms,including the possible requirement of a patient co-payment for Medicare beneficiaries for laboratory tests covered by Medicare, and are subject to change atany time. Reductions in the reimbursement rate of third-party payors have occurred and may occur in the future. Reductions in the prices at which testingservices based on our technology are reimbursed in the future could result in pricing pressures and have a negative impact on our revenue. In many countriesoutside of the United States, various coverage, pricing and reimbursement approvals are required. We expect that it will take several years to establish broadcoverage and reimbursement for testing services based on our products with payors in countries outside of the United States, and our efforts may not besuccessful.45We may be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws and other federal and state healthcare laws applicable toour business and marketing practices. If we are unable to comply, or have not complied, with such laws, we could face substantial penalties.Our operations may be, and may continue to be, directly, or indirectly through our customers, subject to various federal and state fraud and abuse laws,including, without limitation, the federal and state anti-kickback statutes, false claims statutes, civil monetary penalties laws, patient data privacy andsecurity laws, physician transparency laws and marketing compliance laws. These laws may impact, among other things, our proposed sales and marketingand education programs.The laws that may affect our ability to operate include, but are not limited to: •The Federal Anti-kickback Statute, which prohibits, among other things, knowingly and willfully soliciting, receiving, offering or paying anyremuneration (including any kickback, bribe, or rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce, or in return for,either the referral of an individual, or the purchase, lease, order or recommendation of any good, facility, item or service for which payment maybe made, in whole or in part, under a federal healthcare program, such as the Medicare and Medicaid programs; a person or entity does not needto have actual knowledge of the statute or specific intent to violate it to have committed a violation, rather, if one purpose of the remunerationis to induce referrals, the Federal Anti-Kickback Statute is violated. •The federal physician self-referral prohibition, commonly known as the Stark Law, which prohibits, among other things, physicians who have afinancial relationship, including an investment, ownership or compensation relationship with an entity, from referring Medicare and Medicaidpatients to that entity for designated health services, which include clinical laboratory services, unless an exception applies. Similarly, entitiesmay not bill Medicare, Medicaid or any other party for services furnished pursuant to a prohibited referral. Unlike the Federal Anti-KickbackStatute, the Stark Law is a strict liability statute, meaning that all of the requirements of a Stark Law exception must be met in order to becompliant with the law. •Federal civil and criminal false claims laws, including the federal civil False Claims Act, and civil monetary penalties laws, which prohibit,among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment or approval fromMedicare, Medicaid or other governmental third-party payors that are false or fraudulent, knowingly making a false statement material to anobligation to pay or transmit money to the Federal Government or knowingly concealing or knowingly and improperly avoiding or decreasingan obligation to pay money to the Federal Government, which may apply to entities that provide coding and billing advice to customers; theFederal Government may assert that a claim including items or services resulting from a violation of the Federal Anti-Kickback Statuteconstitutes a false or fraudulent claim for purposes of the federal civil False Claims Act. •HIPAA, which created additional federal criminal statutes that prohibit knowingly and willfully executing, or attempting to execute, a schemeto defraud any healthcare benefit program or obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money orproperty owned by, or under the custody or control of, any healthcare benefit program, regardless of the payor (e.g., public or private) andknowingly and willfully falsifying, concealing, or covering up by any trick or device a material fact or making any materially false statementsin connection with the delivery of, or payment for, healthcare benefits, items or services relating to healthcare matters; similar to the FederalAnti-Kickback Statute, a person or entity does not need to have actual knowledge of the healthcare fraud statute or specific intent to violate itto have committed a violation. •HIPAA, as amended by HITECH, and their respective implementing regulations, which impose requirements on certain covered healthcareproviders, health plans, and healthcare clearinghouses as well as their respective business associates that perform services for them that involvethe use, maintenance, or disclosure of individually identifiable health information, relating to the privacy, security and transmission ofindividually identifiable health information. In addition, the EU has established its own data security and privacy legal framework, includingbut not limited to Directive 95/46/EC (“Data Protection Directive”). The Data Protection Directive will be replaced starting in May 2018 withthe recently adopted European General Data Protection Regulation (“GDPR”), which contains new provisions specifically directed at theprocessing of health information, higher sanctions and extra-territoriality measures intended to bring non-EU companies under the regulation.Over time we may expand our business operations to include additional operations in the EU. With such expansion, we would be subjectto increased governmental regulation, including the GDPR, in the EU countries in which we operate.46 •The Federal Physician Payments Sunshine Act, which require certain manufacturers of drugs, devices, biologicals and medical supplies forwhich payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report annuallyto CMS information related to payments or other transfers of value made to physicians and teaching hospitals, as well as applicablemanufacturers and group purchasing organizations to report annually to CMS certain ownership and investment interests held by physiciansand their immediate family members. •State law equivalents of each of the above federal laws, such as anti-kickback, self-referral, and false claims laws which may apply to ourbusiness practices, including but not limited to, research, distribution, sales and marketing arrangements as well as submitting claims involvinghealthcare items or services reimbursed by any third-party payor, including commercial insurers; state laws that require device companies tocomply with the industry’s voluntary compliance guidelines and the applicable compliance guidance promulgated by the Federal Governmentthat otherwise restricts payments that may be made to healthcare providers; state laws that require device manufacturers to file reports withstates regarding marketing information, such as the tracking and reporting of gifts, compensations and other remuneration and items of valueprovided to healthcare professionals and entities (compliance with such requirements may require investment in infrastructure to ensure thattracking is performed properly, and some of these laws result in the public disclosure of various types of payments and relationships, whichcould potentially have a negative effect on our business and/or increase enforcement scrutiny of our activities); and state laws governing theprivacy and security of health information in certain circumstances, many of which differ from each other in significant ways, with differingeffects.Promotional activities for FDA-regulated products have been the subject of significant enforcement actions brought under healthcare reimbursementlaws, fraud and abuse laws, and consumer protection statutes, among other theories. Advertising and promotion of medical devices are also regulated by theFederal Trade Commission and by state regulatory and enforcement authorities. In addition, under the Federal Lanham Act and similar state laws, competitorsand others can initiate litigation relating to advertising claims.In addition, the approval and commercialization of any of our product candidates outside the United States will also likely subject us to foreignequivalents of the healthcare laws mentioned above, among other foreign laws.Because of the breadth of these laws and the narrowness of the statutory exceptions and regulatory safe harbors available under such laws, it ispossible that some of our business activities, including our relationships with physicians and other health care providers, and our evaluation, reagent rentaland collaborative development agreements with customers, and sales and marketing efforts could be subject to challenge under one or more of such laws.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us, we may besubject to penalties, including administrative, civil and criminal penalties, damages, fines, individual imprisonment, disgorgement, exclusion fromparticipation in federal healthcare programs, such as Medicare and Medicaid, contractual damages, reputational harm, additional reporting requirementsand/or oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, andthe curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations.Our employees, independent contractors, principal investigators, consultants, commercial partners and vendors may engage in misconduct or otherimproper activities, including non-compliance with regulatory standards and requirements.We are exposed to the risk of fraud or other misconduct by our employees, independent contractors, principal investigators, consultants, commercialpartners and vendors. Misconduct by these parties could include intentional, reckless or negligent failures to, among other things: (i) comply with theregulations of the FDA, CMS, the Department of Health and Human Services Office of Inspector General (“OIG”) and other similar foreign regulatory bodies;(ii) provide true, complete and accurate information to the FDA and other similar regulatory bodies; (iii) comply with manufacturing standards we haveestablished; (iv) comply with healthcare fraud and abuse laws and regulations in the United States and similar foreign fraudulent misconduct laws; or (v)report financial information or data accurately, or disclose unauthorized activities to us. These laws may impact, among other things, our activities withcollaborators and key opinion leaders, as well as our sales, marketing and education programs. In particular, the promotion, sales, marketing and businessarrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing andother abusive practices. These laws may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customerincentive programs and other business arrangements. Such misconduct could also involve the improper use of information obtained in the course of clinicalstudies, which could result in regulatory sanctions and cause serious harm to our reputation. We currently have a code of conduct applicable to all of ouremployees, but it is not always possible to identify and deter employee misconduct, and our code of conduct and the other precautions we take to detect andprevent this activity may not be effective in controlling unknown or unmanaged risks or losses, or in protecting us from governmental investigations or otheractions or lawsuits stemming from a failure to comply with these laws or regulations. If any such actions are instituted against us, and we are not successful indefending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal andadministrative penalties, damages, monetary fines,47disgorgement, individual imprisonment, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractualdamages, reputational harm, diminished profits and future earnings, additional reporting requirements and/or oversight if we become subject to a corporateintegrity agreement or similar agreement to resolve allegations of non-compliance with these laws, and curtailment of our operations. Any of these actions orinvestigations could result in substantial costs to us, including legal fees, and divert the attention of management from operating our business.Healthcare policy changes, including recently enacted legislation reforming the United States healthcare system, may have a material adverse effect onour financial condition and results of operations.On April 1, 2014, the Protecting Access to Medicare Act of 2014 (“PAMA”) was signed into law, which, among other things, significantly alters thecurrent payment methodology under the Medicare Clinical Laboratory Fee Schedule. Under the new law, starting January 1, 2016 and every three yearsthereafter (or annually in the case of advanced diagnostic lab tests), clinical laboratories must report laboratory test payment data for each Medicare-coveredclinical diagnostic lab test that it furnishes during a period to be defined by future regulations. The reported data must include the payment rate (reflecting alldiscounts, rebates, coupons and other price concessions) and the volume of each test that was paid by each private payor (including health insurance issuers,group health plans, Medicare Advantage plans and Medicaid managed care organizations). Beginning in 2017, the Medicare payment rate for each clinicaldiagnostic lab test will be equal to the weighted median amount for the test from the most recent data collection period. The payment rate will apply tolaboratory tests furnished by a hospital laboratory if the test is separately paid under the hospital outpatient prospective payment system. It is too early topredict the impact on reimbursement for our products in development.Also under PAMA, CMS is required to adopt temporary billing codes to identify new tests and new advanced diagnostic laboratory tests that havebeen cleared or approved by the FDA. For an existing test that is cleared or approved by the FDA and for which Medicare payment is made as of April 1,2014, CMS is required to assign a unique billing code if one has not already been assigned by the agency. In addition to assigning the code, CMS wasrequired to publicly report payment for the tests no later than January 1, 2016. We cannot determine at this time the full impact of the new law on ourbusiness, financial condition and results of operations.The ACA makes changes that could significantly impact the biopharmaceutical and medical device industries and clinical laboratories. For example,the ACA imposes a multifactor productivity adjustment to the reimbursement rate paid under Medicare for certain clinical diagnostic laboratory tests, whichmay reduce payment rates. These or any future proposed or mandated reductions in payments may apply to some or all of the clinical laboratory tests that ourdiagnostics customers use our technology to deliver to Medicare beneficiaries, and may reduce demand for our diagnostic products.Other significant measures contained in the ACA include, for example, coordination and promotion of research on comparative clinical effectivenessof different technologies and procedures, initiatives to revise Medicare payment methodologies, such as bundling of payments across the continuum of careby providers and physicians, and initiatives to promote quality indicators in payment methodologies. Further, the ACA includes a deductible 2.3% excise taxon any entity that manufactures or imports medical devices offered for sale in the United States, with limited exceptions, which became effective January 1,2013. However, the Consolidated Appropriations Act of 2016, signed into law in December 2015, includes a two-year moratorium on the medical deviceexcise tax through December 31, 2017. Further, on January 22, 2018, President Trump signed a continuing resolution on appropriations for fiscal year 2018(the “2018 Appropriations Resolution”) that extended the moratorium on the medical device excise tax through December 31, 2019. Absent furtherlegislative action, the tax will be automatically reinstated for medical device sales beginning January 1, 2020. The ACA also includes significant new fraudand abuse measures, including required disclosures of financial arrangements with physician customers, lower thresholds for violations and increasingpotential penalties for such violations. However, the future of the ACA is uncertain. There have been judicial and Congressional challenges to certain aspectsof the ACA. As a result, there have been delays in the implementation of, and action taken to repeal or replace, certain aspects of the ACA. Since January2017, President Trump has signed two Executive Orders and other directives designed to delay the implementation of certain provisions of the ACA orotherwise circumvent some of the requirements for health insurance mandated by the ACA. Concurrently, Congress has considered legislation that wouldrepeal or repeal and replace all or part of the ACA. While Congress has not passed comprehensive repeal legislation, two bills affecting the implementation ofcertain taxes under the ACA have been signed into law. The 2017 Tax Act includes a provision repealing, effective January 1, 2019, the tax-based sharedresponsibility payment imposed by the ACA on certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonlyreferred to as the “individual mandate”. Additionally, the 2018 Appropriations Resolution delays the implementation of certain ACA-mandated fees,including, without limitation, the medical device excise tax. Congress may consider additional legislation to repeal or repeal and replace other elements ofthe ACA. We continue to evaluate the effect that the ACA and its possible repeal and replacement has on our business.48In addition, other legislative changes have been proposed and adopted since the ACA was enacted. On August 2, 2011, then-President Obama signedinto law the Budget Control Act of 2011, which, among other things, created the Joint Select Committee on Deficit Reduction to recommend to Congressproposals in spending reductions. The Joint Select Committee did not achieve a targeted deficit reduction of at least $1.2 trillion for the years 2013 through2021, triggering the legislation’s automatic reduction to several government programs. This includes reductions to Medicare payments to providers of2% per fiscal year, which went into effect on April 1, 2013, and, following the passage of other legislative amendments, including the Bipartisan Budget Actof 2018, will stay in effect through 2027 unless additional Congressional action is taken. On January 2, 2013, then-President Obama signed into law theAmerican Taxpayer Relief Act of 2012, which, among other things, further reduced Medicare payments to several providers, including hospitals, imagingcenters and cancer treatment centers and increased the statute of limitations period for the government to recover overpayments to providers from three to fiveyears.Various healthcare reform proposals have also emerged from federal and state governments. Changes in healthcare law or policy, such as the creationof broad test utilization limits for diagnostic products in general or requirements that Medicare patients pay for portions of clinical laboratory tests or servicesreceived, could substantially impact the sales of our tests, increase costs and divert management’s attention from our business. Such co-payments byMedicare beneficiaries for laboratory services were discussed as possible cost savings for the Medicare program as part of the debt ceiling budget discussionsin mid-2011 and may be enacted in the future. In addition, sales of our tests outside of the United States will subject us to foreign regulatory requirements,which may also change over time.We cannot predict whether future healthcare initiatives will be implemented at the federal or state level or in countries outside of the United States inwhich we may do business, or the effect any future legislation or regulation will have on us. The taxes imposed by the new federal legislation and theexpansion in government’s effect on the United States healthcare industry may result in decreased profits to us, lower reimbursements by payors for ourproducts or reduced medical procedure volumes, all of which may adversely affect our business, financial condition and results of operations. The full impactof the ACA, as well as other laws and reform measures that may be proposed and adopted in the future, remains uncertain, but may continue the downwardpressure on medical device pricing, especially under the Medicare program, and may also increase our regulatory burdens and operating costs, which couldhave a material adverse effect on our business operations.Risks Related to Intellectual PropertyIf we are unable to protect our intellectual property effectively, our business would be harmed.We rely on patent protection as well as trademark, copyright, trade secret and other intellectual property rights protection and contractual restrictionsto protect our proprietary technologies, all of which provide limited protection and may not adequately protect our rights or permit us to gain or keep anycompetitive advantage. Our U.S. and foreign patent and patent application portfolio relates to our nuclease-protection-based technologies as well as to lungcancer and melanoma and DLBCL biomarker panels discovered using our nuclease-protection-based technology. We have exclusive or non-exclusivelicenses to multiple U.S. and foreign patents and patent applications covering technologies that we may elect to utilize in developing diagnostic tests for useon our HTG EdgeSeq system. Those licensed patents and patent applications cover technologies related to the diagnosis of breast cancer and melanoma.If we fail to protect our intellectual property, third parties may be able to compete more effectively against us and we may incur substantial litigationcosts in our attempts to recover or restrict use of our intellectual property.We cannot assure investors that any of our currently pending or future patent applications will result in issued patents, and we cannot predict howlong it will take for such patents to be issued. Further, we cannot assure investors that other parties will not challenge any patents issued to us or that courts orregulatory agencies will hold our patents to be valid or enforceable. We cannot guarantee investors that we will be successful in defending challenges madeagainst our patents. Any successful third-party challenge to our patents could result in the unenforceability or invalidity of such patents.The patent positions of life sciences companies can be highly uncertain and involve complex legal and factual questions for which important legalprinciples remain unresolved. No consistent policy regarding the breadth of claims allowed in such companies’ patents has emerged to date in the UnitedStates. Furthermore, in the biotechnology field, courts frequently render opinions that may adversely affect the patentability of certain inventions ordiscoveries, including opinions that may adversely affect the patentability of methods for analyzing or comparing nucleic acids molecules, such as RNA orDNA.49The patent positions of companies engaged in development and commercialization of molecular diagnostic tests are particularly uncertain. Variouscourts, including the U.S. Supreme Court, have recently rendered decisions that impact the scope of patentability of certain inventions or discoveries relatingto molecular diagnostics. Specifically, these decisions stand for the proposition that patent claims that recite laws of nature (for example, the relationshipsbetween gene expression levels and the likelihood of risk of recurrence of cancer) are not themselves patentable unless those patent claims have sufficientadditional features that provide practical assurance that the processes are genuine inventive applications of those laws rather than patent drafting effortsdesigned to monopolize the law of nature itself. What constitutes a “sufficient” additional feature is uncertain. Accordingly, this evolving case law in theUnited States may adversely impact our ability to obtain new patents and may facilitate third-party challenges to our existing owned and licensed patents.The laws of some non-U.S. countries do not protect intellectual property rights to the same extent as the laws of the United States, and manycompanies have encountered significant problems in protecting and defending such rights in foreign jurisdictions. The legal systems of certain countries,particularly certain developing countries, do not favor the enforcement of patents and other intellectual property protection, particularly those relating tobiotechnology, which could make it difficult for us to stop the infringement of our patents. Proceedings to enforce our patent rights in foreign jurisdictionscould result in substantial cost and divert our efforts and attention from other aspects of our business.Changes in either the patent laws or in interpretations of patent laws in the United States or other countries may diminish the value of our intellectualproperty. We cannot predict the breadth of claims that may be allowed or enforced in our patents or in third-party patents. For example: •We might not have been the first to make the inventions covered by each of our patents and pending patent applications. •We might not have been the first to file patent applications for these inventions. •Others may independently develop similar or alternative products and technologies or duplicate any of our products and technologies. •It is possible that none of our pending patent applications will result in issued patents, and even if they issue as patents, they may not provide abasis for commercially viable products, may not provide us with any competitive advantages, or may be challenged and invalidated by thirdparties. •We may not develop additional proprietary products and technologies that are patentable. •The patents of others may have an adverse effect on our business. •We apply for patents covering our products and technologies and uses thereof, as we deem appropriate. However, we may fail to apply forpatents on important products and technologies in a timely fashion or at all.In addition to pursuing patents on our technology, we take steps to protect our intellectual property and proprietary technology by entering intoconfidentiality agreements and intellectual property assignment agreements with our employees, consultants, corporate partners and, when needed, ouradvisors. Such agreements may not be enforceable or may not provide meaningful protection for our trade secrets or other proprietary information in theevent of unauthorized use or disclosure or other breaches of the agreements, and we may not be able to prevent such unauthorized disclosure. Monitoringunauthorized disclosure is difficult, and we do not know whether the steps we have taken to prevent such disclosure are, or will be, adequate. If we were toenforce a claim that a third party had illegally obtained and was using our trade secrets, it would be expensive and time consuming, and the outcome wouldbe unpredictable. In addition, courts outside the United States may be less willing to protect trade secrets.In addition, competitors could purchase our products and attempt to replicate some or all of the competitive advantages we derive from ourdevelopment efforts, willfully infringe our intellectual property rights, design around our protected technology or develop their own competitivetechnologies that fall outside of our intellectual property rights. If our intellectual property is not adequately protected so as to protect our market againstcompetitors’ products and methods, our competitive position could be adversely affected, as could our business.We have not yet registered certain of our trademarks, including “HTG Edge,” “HTG EdgeSeq,” “VERI/O,” and “qNPA” in all of our potential markets.If we apply to register these trademarks, our applications may not be allowed for registration, and our registered trademarks may not be maintained orenforced. In addition, opposition or cancellation proceedings may be filed against our trademark applications and registrations, and our trademarks may notsurvive such proceedings. If we do not secure registrations for our trademarks, we may encounter more difficulty in enforcing them against third parties thanwe otherwise would.50To the extent our intellectual property, including licensed intellectual property, offers inadequate protection, or is found to be invalid orunenforceable, we would be exposed to a greater risk of direct competition. If our intellectual property does not provide adequate protection against ourcompetitors’ products, our competitive position could be adversely affected, as could our business. Both the patent application process and the process ofmanaging patent disputes can be time consuming and expensive.We may need to depend on certain technologies that are licensed to us. We would not control these technologies and any loss of our rights to them couldprevent us from selling some of our products.We have entered into several license agreements with third parties for certain licensed technologies that are, or may become relevant to the productswe market, or plan to market. In addition, we may in the future elect to license third party intellectual property to further our business objectives and/or asneeded for freedom to operate for our products. We do not and will not own the patents, patent applications or other intellectual property rights that are asubject of these licenses. Our rights to use these technologies and employ the inventions claimed in the licensed patents, patent applications and otherintellectual property rights are or will be subject to the continuation of and compliance with the terms of those licenses.We might not be able to obtain licenses to technology or other intellectual property rights that we require. Even if such licenses are obtainable, theymay not be available at a reasonable cost or multiple licenses may be needed for the same product (e.g., stacked royalties). We could therefore incursubstantial costs related to royalty payments for licenses obtained from third parties, which could negatively affect our gross margins. Further, we couldencounter delays in product introductions, or interruptions in product sales, as we develop alternative methods or products.In some cases, we do not or may not control the prosecution, maintenance, or filing of the patents or patent applications to which we hold licenses, orthe enforcement of these patents against third parties. As a result, we cannot be certain that drafting or prosecution of the licensed patents and patentapplications by the licensors have been or will be conducted in compliance with applicable laws and regulations or will result in valid and enforceablepatents and other intellectual property rights.Certain of the U.S. patent rights we own, have licensed or may license relate to technology that was developed with U.S. government grants, in whichcase the U.S. government has certain rights in those inventions, including, among others, march-in license rights. In addition, federal regulations imposecertain domestic manufacturing requirements with respect to any products within the scope of those U.S. patent claims.We may be involved in lawsuits to protect or enforce our patent or other proprietary rights, to determine the scope, coverage and validity of others’ patentor other proprietary rights, or to defend against third-party claims of intellectual property infringement, any of which could be time-intensive and costlyand may adversely impact our business or stock price.We may from time to time receive notices of claims of infringement and misappropriation or misuse of other parties’ proprietary rights, including withrespect to third-party trade secrets, infringement by us of third-party patents and trademarks or other rights, or challenges to the validity or enforceability ofour patents, trademarks or other rights. Some of these claims may lead to litigation. We cannot assure investors that such actions will not be asserted orprosecuted against us or that we will prevail in any or all such actions.Litigation may be necessary for us to enforce our patent and other proprietary rights or to determine the scope, coverage and validity of the proprietaryrights of others. The outcome of any litigation or other proceeding is inherently uncertain and might not be favorable to us. In addition, any litigation thatmay be necessary in the future could result in substantial costs, even if we were to prevail, and diversion of resources and could have a material adverse effecton our business, operating results or financial condition.As we move into new markets and applications for our products, incumbent participants in such markets may assert their patents and other proprietaryrights against us as a means of slowing our entry into such markets or as a means to extract substantial license and royalty payments from us. Our competitorsand others may now and in the future have significantly larger and more mature patent portfolios than we currently have. In addition, future litigation mayinvolve patent holding companies or other adverse patent owners who have no relevant product revenue and against whom our own patents may providelittle or no deterrence or protection. Therefore, our commercial success may depend in part on our non-infringement of the patents or proprietary rights ofthird parties. Numerous significant intellectual property issues have been litigated, and will likely continue to be litigated, between existing and newparticipants in our existing and targeted markets and competitors may assert that our products infringe their intellectual property rights as part of a businessstrategy to impede our successful entry into those markets. We have not conducted comprehensive freedom-to-operate searches to determine whether thecommercialization of our products or other business activities would infringe patents issued to third parties. Third parties may assert that we are employingtheir proprietary technology without authorization. In addition, our competitors and others may have patents or may in the future obtain patents and claimthat use of our products infringes these patents. We could incur substantial costs and divert the attention of our management and technical personnel indefending against any of these claims. Parties making claims against us may be able to obtain injunctive or other relief, which could block our ability todevelop, commercialize and sell products, and could result in the award of substantial damages against us. In the event of a successful claim of51infringement against us, we may be required to pay damages and obtain one or more licenses from third parties, or be prohibited from selling certain products.We may not be able to obtain these licenses at a reasonable cost, if at all. We could therefore incur substantial costs related to royalty payments for licensesobtained from third parties, which could negatively affect our gross margins. In addition, we could encounter delays in product introductions while weattempt to develop alternative methods or products to avoid infringing third-party patents or proprietary rights. Defense of any lawsuit or failure to obtainany of these licenses on favorable terms could prevent us from commercializing products, and the prohibition of sale of any of our products could materiallyaffect our ability to grow and gain market acceptance for our products.Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some ofour confidential information could be compromised by disclosure during this type of litigation. In addition, during the course of this kind of litigation, therecould be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceivethese results to be negative, it could have a substantial adverse effect on the price of our common stock.In addition, our agreements with some of our suppliers, distributors, customers and other entities with whom we do business require us to defend orindemnify these parties to the extent they become involved in infringement claims against us, including the claims described above. We could alsovoluntarily agree to defend or indemnify third parties in instances where we are not obligated to do so if we determine it would be important to our businessrelationships. If we are required or agree to defend or indemnify any of these third parties in connection with any infringement claims, we could incursignificant costs and expenses that could adversely affect our business, operating results, or financial condition.We may be subject to damages resulting from claims that we or our employees have wrongfully used or disclosed alleged trade secrets of our employees’former employers.Many of our employees were previously employed at other medical diagnostic companies, including our competitors or potential competitors.Although no claims against us are currently pending, we may be subject to claims that these employees or we have inadvertently or otherwise used ordisclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these claims. If we fail indefending such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights. A loss of key research personnel workproduct could hamper or prevent our ability to commercialize certain potential products, which could severely harm our business. Even if we are successful indefending against these claims, litigation could result in substantial costs and be a distraction to management.Our products contain third-party open source software components, and failure to comply with the terms of the underlying open source software licensescould restrict our ability to sell our products.Our products contain software tools licensed by third-party authors under “open source” licenses. Use and distribution of open source software mayentail greater risks than use of third-party commercial software, as open source licensors generally do not provide warranties or other contractual protectionsregarding infringement claims or the quality of the code. Some open source licenses contain requirements that we make available source code formodifications or derivative works we create based upon the type of open source software we use. If we combine our proprietary software with open sourcesoftware in a certain manner, we could, under certain open source licenses, be required to release the source code of our proprietary software to the public.This would allow our competitors to create similar products with less development effort and time and ultimately could result in a loss of product sales.Although we monitor our use of open source software to avoid subjecting our products to conditions we do not intend, the terms of many open sourcelicenses have not been interpreted by U.S. courts, and there is a risk that these licenses could be construed in a way that could impose unanticipatedconditions or restrictions on our ability to commercialize our products. Moreover, we cannot assure investors that our processes for controlling our use ofopen source software in our products will be effective. If we are held to have breached the terms of an open source software license, we could be required toseek licenses from third parties to continue offering our products on terms that are not economically feasible, to re-engineer our products, to discontinue thesale of our products if re-engineering could not be accomplished on a timely basis, or to make generally available, in source code form, our proprietary code,any of which could adversely affect our business, operating results, and financial condition.We use third-party software that may be difficult to replace or cause errors or failures of our products that could lead to lost customers or harm to ourreputation.We use software licensed from third parties in our products. In the future, this software may not be available to us on commercially reasonable terms, orat all. Any loss of the right to use any of this software could result in delays in the production of our products until equivalent technology is either developedby us, or, if available, is identified, obtained and integrated, which could harm our business. In addition, any errors or defects in third-party software, or otherthird-party software failures could result in errors, defects or cause our products to fail, which could harm our business and be costly to correct. Many of theseproviders attempt to impose limitations on their liability for such errors, defects or failures, and if enforceable, we may have additional liability to ourcustomers or third-party providers that could harm our reputation and increase our operating costs.52We will need to maintain our relationships with third-party software providers and to obtain software from such providers that do not contain anyerrors or defects. Any failure to do so could adversely impact our ability to deliver reliable products to our customers and could harm our results ofoperations.Risks Related to Being a Public CompanyIf we fail to maintain proper and effective internal controls, our ability to produce accurate financial statements on a timely basis could be impaired.We are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act and the rules and regulations of The Nasdaq Stock Market(“Nasdaq”). The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures. Internal control overfinancial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financialstatements in accordance with GAAP. We have performed system and process evaluation and testing of our internal controls over financial reporting to allowmanagement to report annually on the effectiveness of our internal controls over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act.This has required and will require that we incur substantial additional professional fees and internal costs to expand our accounting and finance functionsand that we expend significant management efforts as we continue to make this assessment and ensure maintenance of proper internal controls on an ongoingbasis.If we are not able to comply with the requirements of Section 404 of the Sarbanes-Oxley Act in a timely manner, or if we fail to establish and maintainproper and effective internal control over financial reporting, we may not be able to produce timely and accurate financial statements, and our ability toaccurately report our financial results could be adversely affected. If that were to happen, the market price of our stock could decline and we could be subjectto sanctions or investigations by Nasdaq, the Securities and Exchange Commission (“SEC”) or other regulatory authorities.Changes or modifications in financial accounting standards, including those related to revenue recognition, may harm our results of operations.From time to time, the Financial Accounting Standards Board (“FASB”), either alone or jointly with other organizations, promulgates new accountingprinciples that could have an adverse impact on our financial position, results of operations or reported cash flows. For example, in May 2014, the FASBissued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), and subsequently issued implementation guides (collectively, the “NewRevenue Standard”). The New Revenue Standard supersedes nearly all existing revenue recognition guidance under GAAP and became effective for usbeginning January 1, 2018. We have finalized our assessment of the impact of the New Revenue Standard on our results of operations, and do not believe itwill have a material impact on revenue recognized. Our financial disclosures are required to be updated to reflect the New Revenue Standard beginning withour quarterly report on Form 10Q for the quarter ending March 31, 2018. Our inability to adopt the New Revenue Standard or any new accounting standardcorrectly, or to update or modify our internal controls as needed, by the mandated adoption dates could adversely affect our financial reporting obligations,corresponding regulatory compliance and/or investors’ confidence in us. Also, if we were to change our critical accounting estimates, including those relatedto the recognition of collaboration revenue and other revenue sources, our operating results could be significantly affected.Complying with the laws and regulations affecting public companies will increase our costs and the demands on management and could harm ouroperating results.As a public company, we will continue to incur significant legal, accounting and other expenses. The Exchange Act requires, among other things, thatwe file annual, quarterly and current reports with respect to our business and operating results. In addition, the Sarbanes-Oxley Act and rules subsequentlyimplemented by the SEC and Nasdaq, impose numerous requirements on public companies, including requiring changes in corporate governance practices.Our management and other personnel will need to continue to devote a substantial amount of time to compliance with these laws and regulations. Theserequirements have resulted in significant legal, accounting, and financial compliance costs and have made and will continue to make some activities moretime consuming and costly.As an “emerging growth company,” we have availed ourselves of the exemption from the requirement that our independent registered publicaccounting firm attest to the effectiveness of our internal control over financial reporting under Section 404. However, we may no longer avail ourselves ofthis exemption when we cease to be an “emerging growth company.” When our independent registered public accounting firm is required to undertake anassessment of our internal control over financial reporting, the cost of our compliance with Section 404 will correspondingly increase. Our compliance withapplicable provisions of Section 404 will require that we incur substantial accounting expense and expend significant management time on compliance-related issues as we implement additional corporate governance practices and comply with reporting requirements. Moreover, if we are not able to complywith the requirements of Section 404 applicable to us in a timely manner, or if we or our independent registered public accounting53firm identifies deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the market price of our stock coulddecline and we could be subject to sanctions or investigations by the SEC or other regulatory authorities, which would require additional financial andmanagement resources.Furthermore, investor perceptions of our company may suffer if deficiencies are found, and this could cause a decline in the market price of our stock.Irrespective of compliance with Section 404, any failure of our internal control over financial reporting could have a material adverse effect on our statedoperating results and harm our reputation. If we are unable to implement these requirements effectively or efficiently, it could harm our operations, financialreporting, or financial results and could result in an adverse opinion on our internal controls from our independent registered public accounting firm.We are an “emerging growth company,” and any decision on our part to comply only with certain reduced reporting and disclosure requirementsapplicable 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, enacted in April 2012, and for as long as we continue to be an “emerging growthcompany,” we may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to “emerginggrowth companies,” including, but not limited to, not being required to have our independent registered public accounting firm audit our internal controlover financial reporting under Section 404, 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 stockholder approval of any golden parachutepayments not previously approved. We could be an “emerging growth company” for up to five years following the completion of our initial public offeringin May 2015, however, we would cease to be an “emerging growth company” before the end of that five-year period as of the following December 31, if wehave more than approximately $1.0 billion in annual revenue, or if the market value of our common stock that is held by non-affiliates exceeds $700 millionas of June 30 of any year, or as of the date we issue more than $1.0 billion of non-convertible debt over a three-year period. We cannot predict if investors willfind our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as a result of anychoices to reduce future disclosure, there may be a less active trading market for our common stock and our stock price may be more volatile.Risks Related to Our Common StockIf we are unable to continue to satisfy the applicable continued listing requirements of Nasdaq, our common stock could be delisted.Our common stock is currently listed on The Nasdaq Capital Market under the symbol “HTGM.” Effective April 17, 2017, the listing of our commonstock was transferred to The Nasdaq Capital Market from The Nasdaq Global Market following our appeal to a Nasdaq Hearings Panel (“Panel”) of thedelisting notice we received from Nasdaq on February 14, 2017. On April 12, 2017, the Panel found us in compliance with the requirements for listing on TheNasdaq Capital Market as a result of the market value of our outstanding common stock exceeding $35.0 million, which satisfied Nasdaq’s market value oflisted securities (“MVLS”) listing standard. On July 31, 2017, we received a notice from Nasdaq that we were no longer in compliance with the applicableMVLS requirement for continued listing on The Nasdaq Capital Market. We regained compliance with the applicable MVLS requirement for continuedlisting on The Nasdaq Capital Market in January 2018 following completion of our underwritten public offering. In order to maintain this listing, we mustcontinue to satisfy minimum financial and other continued listing requirements and standards. There can be no assurance that we will be able to continue tocomply with the applicable listing standards. If we were not able to comply with applicable listing standards, our shares of common stock would be subject todelisting. The delisting of our common stock from trading on Nasdaq may have a material adverse effect on the market for, and liquidity and price of, ourcommon stock and impair our ability to raise capital. Delisting from Nasdaq could also have other negative results, including, without limitation, thepotential loss of confidence by customers and employees, the loss of institutional investor interest and fewer business development opportunities. In theevent that our common stock is delisted from Nasdaq and is not eligible for quotation or listing on another market or exchange, trading of our common stockcould be conducted only in the over-the-counter market or on an electronic bulletin board established for unlisted securities such as the Pink Sheets or theOTC Bulletin Board. In such event, it could become more difficult to dispose of, or obtain accurate price quotations for, our common stock, and there wouldlikely also be a reduction in our coverage by securities analysts and the news media, which could cause the price of our common stock to decline further.We expect that our stock price will fluctuate significantly.The trading price of our common stock may be highly volatile and could be subject to wide fluctuations in response to various factors, some of whichare beyond our control. These factors include: •actual or anticipated quarterly variation in our results of operations or the results of our competitors; •announcements by us or our competitors of new products, significant contracts, commercial relationships or capital commitments;54 •failure to obtain or delays in obtaining product approvals or clearances from the FDA or foreign regulators; •adverse regulatory or reimbursement announcements; •issuance of new or changed securities analysts’ reports or recommendations for our stock; •developments or disputes concerning our intellectual property or other proprietary rights; •commencement of, or our involvement in, litigation; •market conditions in the life sciences and molecular diagnostics markets; •manufacturing disruptions; •any future sales of our common stock or other securities; •any change to the composition of our board of directors, executive officers or key personnel; •our failure to meet applicable Nasdaq listing standards and the possible delisting of our common stock from Nasdaq; •announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures or capital commitments; •general economic conditions and slow or negative growth of our markets; and •the other factors described in this report under the caption “Risk Factors – Risks Related to Our Common Stock.”The stock market in general, and market prices for the securities of health technology companies like ours in particular, have from time to timeexperienced volatility that often has been unrelated to the operating performance of the underlying companies. These broad market and industry fluctuationsmay adversely affect the market price of our common stock, regardless of our operating performance. In several recent situations where the market price of astock has been volatile, holders of that stock have instituted securities class action litigation against the company that issued the stock. If any of ourstockholders were to bring a lawsuit against us, the defense and disposition of the lawsuit could be costly and divert the time and attention of ourmanagement and harm our operating results.In addition, to date our common stock has generally been sporadically and thinly traded. As a consequence, the trading of relatively small quantitiesof our shares may disproportionately influence the price of our common stock in either direction. The price for our common stock could decline precipitouslyif even a moderate amount of our common stock is sold on the market without commensurate demand.If securities or industry analysts do not publish research reports about our business, or if they issue an adverse opinion about our business, our stock priceand trading volume could decline.The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or ourbusiness. If one or more of the analysts who cover us issues an adverse opinion about our company, our stock price would likely decline. If one or more ofthese analysts ceases coverage of us or fails to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause ourstock price or trading volume to decline.Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall.Sales of a substantial number of shares of our common stock in the public market or the perception that these sales might occur, could depress themarket price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict theeffect that sales may have on the prevailing market price of our common stock.Future sales and issuances of our common stock or rights to purchase common stock, including pursuant to our equity incentive plans, could result inadditional dilution of the percentage ownership of our stockholders and could cause our stock price to fall.We expect that significant additional capital will be needed in the future to continue our planned operations. We may sell common stock, convertiblesecurities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. If we sell common stock, convertiblesecurities or other equity securities in more than one transaction, investors may be materially diluted by these and subsequent sales. New investors could alsogain rights superior to our existing stockholders.Pursuant to our 2014 Equity Incentive Plan (“2014 Plan”) our board of directors is authorized to grant stock options and other equity-based awards toour employees, directors and consultants. The number of shares available for future grant under the 2014 Plan will automatically increase on January 1 ofeach year by 4% of the total number of shares of our common stock outstanding on55December 31 of the preceding calendar year, subject to the ability of our board of directors to take action to reduce the size of the increase in any given year.In addition, our board of directors approved the granting of rights to eligible employees to purchase shares of our common stock pursuant to our 2014Employee Stock Purchase Plan (“ESPP”) beginning January 1, 2016. The number of shares of our common stock reserved for issuance under the ESPP willautomatically increase on January 1 of each calendar year by the lesser of 1% of the total number of shares of our common stock outstanding on December 31of the preceding calendar year and 195,000 shares, subject to the ability of our board of directors to take action to reduce the size of the increase in any givenyear. Currently, we plan to register the increased number of shares available for issuance under the 2014 Plan and ESPP each year. Increases in the number ofshares available for future grant or purchase may result in additional dilution, which could cause our stock price to decline.Our principal stockholders and management own a significant percentage of our stock and will be able to exercise significant influence over matterssubject to stockholder approval.Our executive officers, directors and principal stockholders, together with their respective affiliates, beneficially owned a significant portion of ourcapital stock at December 31, 2017. Accordingly, our executive officers, directors and principal stockholders acting together could exercise significantinfluence over all matters requiring stockholder approval, including mergers and other business combinations. This concentration of ownership could havethe effect of delaying or preventing a change in our control or otherwise discouraging a potential acquirer from attempting to obtain control of us, which inturn could have a material adverse effect on our stock price and may prevent attempts by our stockholders to replace or remove the board of directors ormanagement.We do not intend to pay dividends on our common stock in the foreseeable future.We have never declared or paid any cash dividend on our common stock. We currently anticipate that we will retain future earnings for thedevelopment, operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. In addition,our ability to pay cash dividends is currently prohibited by the terms of our debt facility, and any future debt financing arrangement may contain termsprohibiting or limiting the amount of dividends that may be declared or paid on our common stock. Any return to stockholders will therefore be limited tothe appreciation of their stock.Provisions in our amended and restated certificate of incorporation and bylaws, as well as provisions of Delaware law, could make it more difficult for athird party to acquire us or increase the cost of acquiring us, even if doing so would benefit our stockholders or remove our current management.Some provisions of our charter documents and Delaware law may have anti-takeover effects that could discourage an acquisition of us by others, evenif an acquisition would be beneficial to our stockholders and may prevent attempts by our stockholders to replace or remove our current management. Theseprovisions include: •authorizing the issuance of “blank check” preferred stock, the terms of which may be established and shares of which may be issued withoutstockholder approval; •limiting the removal of directors by the stockholders; •creating a staggered board of directors; •prohibiting stockholder action by written consent, thereby requiring all stockholder actions to be taken at a meeting of our stockholders; •eliminating the ability of stockholders to call a special meeting of stockholders; and •establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted uponat stockholder meetings.These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficultfor stockholders to replace members of our board of directors, which is responsible for appointing the members of our management. In addition, we are subjectto Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range ofbusiness combinations with an interested stockholder for a period of three years following the date on which the stockholder became an interestedstockholder, unless such transactions are approved by our board of directors. This provision could have the effect of delaying or preventing a change ofcontrol, whether or not it is desired by or beneficial to our stockholders. Further, other provisions of Delaware law may also discourage, delay or preventsomeone from acquiring us or merging with us.56Item 1B. Unresolved Staff CommentsNone.Item 2. Properties.Our 30,100 square feet of corporate facilities, including our administrative, laboratory and manufacturing spaces, are located in Tucson, Arizona. Weoccupy these facilities pursuant to two separate leases. The first lease concerns 17,500 square feet housing our administrative, manufacturing, and lab servicesfacilities. The second lease concerns 12,600 square feet of space used for our research and development facilities. We amended these facilities leases inAugust 2015 to, among other things, align and extend the lease terms to expire in January 2021. In connection with the first lease term extension the landlordagreed to perform certain capital improvements to expand and improve the existing manufacturing facilities. In addition, we completed the expansion andimprovement of our administrative and research and development facilities, resulting in the capitalization of additional leasehold improvements in 2016,which will be amortized over the remaining life of the lease. Base rent payable under the first lease is approximately $27,000 per month, and base rentpayable under the second lease is approximately $16,000 per month, in each case for the remaining terms of the respective leases. The aggregate rentspayable over the renewal term of the amended first lease represent an increase of $804,000, over the prior term rental rates for a five-year period. The amendedsecond lease specified no rent increase over the prior term and the annual rent increases for the applicable space were eliminated.Our landlord holds security deposits equal to a total of approximately $23,000. We believe that our existing facilities are adequate to meet ourbusiness requirements for the reasonably foreseeable future and that additional space will be available on commercially reasonable terms, if required.Item 3. Legal Proceedings.We are not engaged in any material legal proceedings. However, in the normal course of business, we may from time to time be named as a party tolegal claims, actions and complaints, including matters involving employment, intellectual property others.Item 4. Mine Safety Disclosures.Not applicable. 57PART IIItem 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.Market InformationOur common stock is traded on The Nasdaq Capital Market under the symbol “HTGM.” Trading of our common stock commenced on May 6, 2015 inconnection with our initial public offering. The following table sets forth, for the periods indicated, the high and low sales prices for our common stock asreported by The Nasdaq Stock Market. Year ended December 31, 2016 High Low First quarter 4.68 2.03 Second quarter 4.17 2.07 Third quarter 3.09 2.13 Fourth quarter 4.45 1.82 Year ended December 31, 2017 High Low First quarter 13.25 1.20 Second quarter 8.15 2.62 Third quarter 2.80 1.59 Fourth quarter 3.03 1.65 On March 16, 2018, the last reported sale price of our common stock was $4.96 per share.HoldersAs of March 16, 2018, there were approximately 183 holders of record of our common stock. The actual number of stockholders is greater than thisnumber of record holders and includes stockholders who are beneficial owners but whose shares are held in street name by brokers and other nominees.DividendsWe have never declared or paid any cash dividends on our common stock. We anticipate that we will retain all available funds and any futureearnings, if any, for use in the operation of our business and do not anticipate paying cash dividends in the foreseeable future. In addition, our term loanagreement materially restricts, and future debt instruments we issue may materially restrict, our ability to pay dividends on our common stock. Payment offuture cash dividends, if any, will be at the discretion of the board of directors after considering various factors, including our financial condition, operatingresults, current and anticipated cash needs, the requirements of current or then-existing debt instruments and other factors the board of directors deemsrelevant.Item 6. Selected Financial Data.We are a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and are not required to provide the information otherwise requiredunder this item. 58Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.You should read the following discussion and analysis together with our financial statements and related notes included elsewhere in this AnnualReport. The following discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially fromthose expressed or implied in any forward-looking statements due to various factors, including those set forth under the caption “Item 1A. Risk Factors.” Allforward-looking statements included in this Annual Report are based on information available to us as of the time we file this Annual Report and, except asrequired by law, we undertake no obligation to update publicly or revise any forward-looking statements. In addition, statements that “we believe” andsimilar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of thisAnnual Report, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and ourstatements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information.These statements are inherently uncertain.OverviewWe are a commercial stage company that develops and markets products and services based on a proprietary technology that facilitates the routine useof targeted molecular profiling using a small amount of biological sample. Molecular profiling is the collection of information about multiple moleculartargets, such as DNA and RNA, also called biomarkers, in a biological sample. Molecular profiling information has many important applications, from basicresearch to molecular diagnostics in personalized medicine. Our technology can be used throughout that range of applications, which is just one of its manybenefits. Our focus is on clinical applications. Our primary customers include biopharmaceutical companies, academic research centers and molecular testinglaboratories.As part of our business model, we seek to leverage key business drivers in molecular profiling, including the acceleration of precision medicine, themigration of molecular testing to next generation sequencing, the movement to less invasive biopsies, the need for greater diagnostic sensitivity, the need toconform to changing healthcare economics and the need for automation and an easily deployable workflow. Our products include instrumentation (orplatforms), consumables, including assay kits, and software analytics that, as an integrated system, automate sample processing and can quickly, robustly andsimultaneously profile tens, hundreds or thousands of molecular targets from samples a fraction of the size required by prevailing technologies. Our objectiveis to establish our solutions as the standard in molecular profiling, and to make their benefits accessible to all molecular labs from research to the clinic. Webelieve that our target customers desire high quality molecular profiling information in a multiplexed panel format from increasingly smaller and lessinvasive samples, with the ability to collect such information locally to minimize turnaround time and cost.In 2014, we launched our HTG EdgeSeq technology, which generates a molecular profiling library for detection of RNA using NGS. Our HTGEdgeSeq assays are automated on our HTG EdgeSeq platform. Our innovative platform and menu of molecular profiling panels is being utilized by a widerange of customers including biopharmaceutical companies, academic institutions and molecular labs to simultaneously analyze a comprehensive set ofmolecular information from valuable clinical samples and improve the lab’s workflow efficiency. Customers can also obtain the advantages of our proprietarytechnologies by engaging our VERI/O laboratory for pre-clinical and clinical research-related services. We currently market several proprietary molecularprofiling panels that address the needs of customers in translational research, biomarker discovery and potentially companion diagnostics. In addition, wehave a focused development pipeline that includes planned panels for translational research, drug development and molecular diagnostics. Our productstrategy is to develop a suite of profiling panels with initial focus in immuno-oncology and next generation pathology.We have two primary sources of revenue: revenue from research use only (“RUO”) profiling for biopharmaceutical companies, academic researchcenters and molecular testing laboratories; and revenue from collaborative development services for companion diagnostic development programs forbiopharmaceutical companies. RUO profiling revenue includes customer purchases of our HTG EdgeSeq instrument and related RUO assay kits, and the useof our HTG EdgeSeq instruments and RUO assay kits to process samples on the customer’s behalf in our VERI/O laboratory. Collaborative developmentrevenue relates to services performed primarily for biopharmaceutical companies pursuant to our Master Assay Development, Commercialization andManufacturing Agreement (“Governing Agreement”) with QIAGEN Manchester Limited (“QML”), a wholly owned subsidiary of QIAGEN N.V. Under theGoverning Agreement, our HTG EdgeSeq proprietary technology is utilized to develop, seek regulatory approval for and commercialize companiondiagnostic assays for biopharmaceutical drug candidates and corresponding therapeutics.We have incurred significant losses since our inception, and we have never been profitable. We incurred net losses of $19.0 million and $26.0 millionfor the years ended December 31, 2017 and 2016, respectively, and had an accumulated deficit of $134.6 million as of December 31, 2017. As of December31, 2017, we had available cash and cash equivalents totaling approximately $10.0 million and had current liabilities of approximately $13.3 million andlong-term liabilities of approximately $11.0 million, primarily attributable to our NuvoGen and QNAH Convertible Note obligations.59Recent DevelopmentsIn January 2018, we entered into a third statement of work under the Governing Agreement with QML. SOW Three relates to development activitiesfor a NGS-based clinical-trial assay (the “SOW Three Project”) in connection with a sponsor project agreement (the “Project Agreement”) between QML and apharmaceutical company (“Pharma Three”). The SOW Three Project is one of three development programs, each for a different pharmaceutical company,announced to date under the Governing Agreement. If successfully completed, the SOW Three Project is expected to lead to subsequent assay developmentactivities and the potential commercialization of a companion diagnostic assay for a corresponding Pharma Three drug.In January 2018, we entered into an underwriting agreement (the “Underwriting Agreement”) with Leerink Partners LLC and Cantor Fitzgerald & Co.(“Cantor”), as representatives of the several underwriters named therein, relating to the issuance and sale in a public offering of shares of our common stockbeing offered and sold pursuant to our shelf registration statement on Form S-3 (File No. 333-216977), previously filed with the SEC and declared effectiveby the SEC on April 6, 2017. On January 23, 2018, we completed an underwritten public offering of 13,915,000 shares of our common stock pursuant to theUnderwriting Agreement at a price to the public of $2.90 per share, including 1,815,000 shares sold pursuant to the exercise in full of the underwriters’ optionto purchase additional shares. All of the shares in the offering were sold by us. The aggregate net proceeds from the offering were approximately $37.7million, after deducting underwriting discounts and commissions and offering expenses.In January 2018, we and BMS amended the terms of our May 2016 collaboration agreement to increase the development fee payable by BMS to us foreach of the two initial custom RUO assays contemplated by the collaboration agreement from a low six-figure dollar amount to a mid six-figure dollaramount, and to modify certain assay development requirements. We estimate that the first custom RUO assay development project under the collaborationagreement will be completed in the third quarter of 2018. If successfully completed, we believe this development project will lead to future revenue fromlaboratory services and/or custom RUO assay kits purchased by BMS and/or its subcontractors.In December 2017, we entered into a Master Collaboration Agreement for translational programs with Merck KGaA. The Master CollaborationAgreement complements our Master Companion Diagnostic Agreement with Merck KGaA and includes a statement of work with EMD Serono, thebiopharmaceutical business of Merck KGaA, in the United States and Canada. Under the EMD Serono statement of work, we plan to develop and manufacturea custom profiling assay to support biomarker research for six indications within Merck KGaA’s drug development pipeline. The assay is expected to bekitted for use on HTG EdgeSeq instruments acquired by Merck KGaA and/or their contract research organization partners.Factors Affecting our PerformanceOur business model has evolved and expanded in recent years primarily due to our success in the development of a biopharmaceutical customer base,entry into collaboration agreements with certain biopharmaceutical customers and changing customer demand from product sales to service offerings in ourVERI/O laboratory. We believe the mix of product- and service-based revenues will continue to evolve over time as our product menu expands and,particularly, if we successfully develop one or more companion diagnostic products as a result of our work with biopharmaceutical customers. We believethat our future results of operations are dependent on several factors discussed below. While each of these areas present significant opportunities for us, theyalso pose significant risks and challenges that we must successfully address. See the section entitled “Risk Factors” for further discussion of these risks.Biopharmaceutical Biomarker and Companion Diagnostic SolutionsBiopharmaceutical companies are working to improve the efficacy of their drugs by better targeting appropriate patients for specific therapies. Ourproducts and services are being used by our biopharmaceutical company customers to identify molecular biomarkers that can help determine which patientswill or will not respond to a drug candidate. These customers can obtain the benefits of our technology by purchasing our platform and assays for theirinternal use or by engaging us to perform certain services. Our VERI/O laboratory offers support for our biopharmaceutical customers in biomarker researchand companion diagnostic development, and further expands our traditional service offerings, including molecular profiling of retrospective cohorts tosupport development of targeted and immuno-oncology therapies, building custom research-use-only panels to support early stage clinical programs anddeveloping investigational-use companion diagnostic assays for use in Phase 3 registration trials. We believe our product and service solutions provide uswith a growing number of opportunities to collaborate with biopharmaceutical companies in their drug development programs. Because our technology isbeing used for biomarker detection and, ultimately, patient registration in such programs, we believe we are well positioned to manufacture andcommercialize high-value companion diagnostic assays required in the corresponding drug approvals. We track our pipeline of biopharmaceutical companyprograms as well as the number of such customers with whom we are working to measure our progress.60Customer Adoption of HTG TechnologyToday we believe the primary measure of adoption for our technology is our companion diagnostic pipeline with biopharmaceutical companiesdiscussed above. In the future, we expect increased sales of our instruments and consumables to our pharmaceutical company customers or their contractors tosupport their internal research and drug development efforts and, as discussed below, to other customers as we add to our assay menu and, especially, as welaunch high value diagnostic, including companion diagnostic, products. We currently market and sell, on a limited and targeted basis, our research use onlyapplications to biopharmaceutical companies, academic translational research centers and in Europe, molecular testing labs.Our ability to increase instrument and consumable revenue depends on several factors, including (i) adoption of our HTG EdgeSeq platforms by ourcustomer base, including increasing market share for our proprietary panels for the research market; (ii) the efforts of our sales and marketing teams todemonstrate the utility of our products and technology; (iii) our ability to develop and market novel molecular profiling panels designed to meet customerneeds, including unmet medical needs; (iv) our ability to demonstrate the benefits of our products to key opinion leaders so they will publish informationsupporting those benefits; (v) pricing and reimbursement; (vi) our ability to expand the addressable market of our HTG EdgeSeq platform through thedevelopment of new applications; (vii) our product capabilities compared with competition; and (viii) successful outcomes to our companion diagnosticcollaborations. Given the length of our sales cycle, we have in the past experienced, and will likely in the future experience, fluctuations in our instrumentand consumables sales on a period-to-period basis.A key element of increasing adoption of our technology measured by instrument placements is our assay and panel “menu.” Menu is defined as whatassays are available for use on the instruments to satisfy customer needs. To sell additional instruments, grow our installed base and drive larger consumableannuities we must develop and commercialize new assays. Our arrangements with biopharmaceutical companies are expected to generate new menu items inaddition to our diagnostic development strategies in immuno-oncology and next generation pathology. As of December 31, 2017, we had an installed baseof 44 HTG systems in various stages of use, including units that are under evaluation and an additional three instruments installed at third party sites insupport of companion diagnostic collaborative development services projects. We remain focused on high quality instrument placements and consumablepull through as the primary indicators of commercial adoption and success in our business.Timing and effectiveness of research and development expensesOur spending on research and development might vary substantially from period to period due to the availability and cost of clinical samples,prioritization of research and development projects or timing of milestone payments under our technology development agreements. This variability is alsorelated to costs incurred in our collaborative development programs, whereby the quantity of HTG EdgeSeq assay kits and instruments, third partysequencing equipment, and third party or internal labor required to complete each of the development milestones under these agreements, which costs areexpensed to research and development expense in our statements of operations, may cause these expenses to vary significantly from one period to the next.We have instituted a stage-gate based method of new product development managed by our innovation council, led by our Chief Executive Officer. Programprogress and priorities are assessed by time, quality and adherence to budgetary metrics at each phase of the project.Financial Operations Overview and Results of OperationsComparison of the Years Ended December 31, 2017 and 2016 Years Ended December 31, Change 2017 2016 $ % Revenue: Product and product-related services $6,797,255 $5,132,730 $1,664,525 32%Collaborative development services 7,962,312 — 7,962,312 100%Total revenue 14,759,567 5,132,730 9,626,837 188%Cost of revenue 4,971,806 4,135,884 835,922 20%Gross margin 9,787,761 996,846 8,790,915 882%Gross margin percentage 66% 19% Operating expenses: Selling, general and administrative 17,513,742 17,427,777 85,965 0%Research and development 9,996,627 7,900,311 2,096,316 27%Total operating expenses 27,510,369 25,328,088 2,182,281 9%Operating loss (17,722,608) (24,331,242) 6,608,634 (27%)Other expense, net (1,234,488) (1,698,190) 463,702 (27%)Net loss before income taxes $(18,957,096) $(26,029,432) $7,072,336 (27%)61RevenueWe generate revenue from two primary sources: revenue from RUO profiling for biopharmaceutical companies, academic research centers andmolecular testing laboratories; and revenue from collaborative development services for biopharmaceutical companies under our companion diagnosticdevelopment programs.RUO profiling is currently made available to our customers through product sales and service offerings. Customers can purchase our HTG EdgeSeqinstrument and related consumables, which consist primarily of our proprietary molecular profiling panels and other assay components. Customers can alsoaccess our technology through contracted services. We perform these services using our HTG EdgeSeq instruments and RUO assay kits to process samples inour VERI/O laboratory. Our proprietary technology is also used to develop custom RUO assay kits expected to generate future sample processing or RUOassay kit revenue.In 2017, we began generating revenue from collaborative development services primarily relating to our Governing Agreement with QML. SOW Onewas entered into in June 2017 and SOW Two was entered into in October 2017. Under these agreements, we and QML combine our technological andcommercial strengths to offer biopharmaceutical companies a complete NGS-based solution for the development, manufacture and commercialization ofcompanion diagnostic assays in support of and in conjunction with, biopharmaceutical companies’ drug development programs.Total revenue for the year ended December 31, 2017 increased by 188% to $14.8 million compared with total revenue of $5.1 million for the yearended December 31, 2016. The increase in total revenue was primarily driven by the initiation of collaborative development services in 2017, as well asincreased demand for our RUO service offerings by our expanding customer base primarily in the United States and Europe.Product and product-related services revenueProduct and product-related services revenue from the sale of our RUO HTG EdgeSeq instruments and consumables and from services performed forcustomers in our VERI/O laboratory using this proprietary RUO technology was $6.8 million compared with $5.1 million for the year ended December 31,2016, and was comprised of the following: Years Ended December 31, Change 2017 2016 $ % Product revenue: Instruments $385,143 $522,813 (137,670) (26%)Consumables 1,463,347 2,237,129 (773,782) (35%)Total product revenue 1,848,490 2,759,942 (911,452) (33%)Product-related services revenue: Custom RUO assay development 419,515 235,818 183,697 78%Sample processing 4,529,250 2,136,970 2,392,280 112%Total product-related services revenue 4,948,765 2,372,788 2,575,977 109%Total product and product-related services revenue $6,797,255 $5,132,730 1,664,525 32% Product revenue generated from the sale of our instruments and RUO assay kits for the year ended December 31, 2017 was $1.8 million compared with$2.8 million for the year ended December 31, 2016, and represented 13% and 54% of our total revenue for the years ended December 31, 2017 and 2016,respectively. The decrease in product revenue from 2017 to 2016 is primarily attributable to our focus on biopharmaceutical customers whose preference hasbeen to access our technology via services through our VERI/O laboratory.Service revenue, consisting of sample processing using our HTG EdgeSeq instruments and consumables and custom RUO assay development,increased from $2.4 million for the year ended December 31, 2016 to $4.9 million for the year ended December 31, 2017, and represented 35% and 46% ofour total revenue for the years ended December 31, 2017 and 2016, respectively. The increase in service revenue for the period ended December 31, 2017compared with 2016 reflects our success in growing the number of biopharmaceutical company customers who have chosen our proprietary technologies foruse in their translational research and drug development programs and who prefer to gain access to our technology through purchase of our services. Ourincrease in service revenue reflects increased consumption of our RUO assay kits used in the processing of samples in our VERI/O laboratory. We expect ourrevenue mix to continue to contain a higher portion of biopharmaceutical service revenue in the near term until we enter the commercial clinical diagnosticmarket.62Collaborative development services revenueCollaborative development services revenue includes services performed on newly initiated biopharmaceutical company companion diagnosticdevelopment programs using our HTG EdgeSeq proprietary technology to develop, seek regulatory approval for and commercialize clinical diagnosticassays for biopharmaceutical company drug candidates and corresponding therapeutics. Collaborative development services revenue, consisting of servicesperformed for two large biopharmaceutical companies pursuant to SOW One and SOW Two under our Governing Agreement with QML, was approximately$8.0 million or 54% of our revenue for the year ended December 31, 2017, which included approximately $2.3 million in profit sharing payments. We had nocollaborative development services revenue for the year ended December 31, 2016, as SOW One was initiated in June 2017.Because of existing agreements with biopharmaceutical company customers (including SOW Three entered into for collaborative developmentservices on an additional biopharmaceutical company program pursuant to our Governing Agreement with QML in January 2018) we expect ourcollaborative development services revenue to increase in both absolute dollars and as a percentage of total revenue for the year ending December 31, 2018.However, the amount or timing of work we perform, the timing and number of development deliverables and the timing and amount of any profit sharingpayments under these agreements could result in significant variability in the timing and amount of revenue recognized in one or more fiscal periods. Forexample, we expect that the collaborative services revenue, and therefore our total revenue, recognized during an individual quarter within 2018 may belower than the collaborative development services revenue and total revenue we recognized during the quarter ended December 31, 2017.Cost of revenue and gross marginCost of revenue includes the aggregate costs incurred in manufacturing, delivering, installing and servicing instruments and consumables, as well asthe costs incurred for services performed for customers in our VERI/O laboratory and product development group. The components of our 2017 cost ofrevenue are material, subcomponent and service costs, manufacturing costs incurred internally (which include direct labor costs), and equipment andinfrastructure expenses associated with the manufacturing and distribution of our products. Additionally, internal costs incurred in our VERI/O laboratoryand in product development, including direct labor and consumables, are included in cost of revenue. Our cost of revenue includes significant fixed costscomprised primarily of manufacturing and service headcount, field service engineers and facilities. Our facilities costs increased in 2016 with capitalimprovements made to our manufacturing facilities in the first quarter of 2016 to allow us to begin manufacturing our instruments internally and to improveour customer service throughput and capabilities. Due to the fixed nature of expenses associated with direct labor, equipment and infrastructure, we expectour cost of revenue as a percentage to decrease over time as we increase product and product-related services revenue, further absorbing these fixed costs.Cost of revenue increased by $835,922, or 20%, for the year ended December 31, 2017 compared with the year ended December 31, 2016, while grossmargin improved to 66% for the year ended December 31, 2017 compared to 19% for the year ended December 31, 2016. This gross margin improvement isprimarily attributable to the initiation of two companion diagnostic development programs under our Governing Agreement with QML in 2017, the revenuefrom which is accounted for in collaborative development services revenue in our statements of operations. The development costs associated withcollaborative development services revenue are included in research and development expense in our statements of operations for the year ended December31, 2017. We anticipate variability in collaborative development services revenue from one quarter to the next. This will likely result in gross marginvariability between fiscal periods. Increased sample processing services through our VERI/O laboratory for the year ended December 31, 2017 whencompared to the year ended December 31, 2016 further accounted for the increase in cost of revenue year over year. Despite the year over year increase indirect material and labor costs incurred in our VERI/O laboratory to generate increased sample processing and custom RUO assay development servicerevenue, additional gross margin improvement is attributable to an overall increase in service revenue. This has resulted in further absorption of our fixedoperating expenses which occurred in the expansion of our VERI/O laboratory staffing, facilities and equipment to accommodate the anticipated increase indemand for services when compared to prior years.Research and development expensesResearch and development expenses represent amounts incurred to perform collaborative development services, costs to develop new proprietarypanels and corresponding assays, to obtain FDA approval for our first U.S. IVD assay and to continue to develop and improve our HTG EdgeSeq platform.These expenses include payroll and related expenses, consulting expenses, laboratory supplies, facilities and equipment. Research and development costs areexpensed as incurred. Research and development expenses increased by $2.1 million, or 27%, for the year ended December 31, 2017 compared with the yearended December 31, 2016. This increase is primarily due to collaborative development costs associated with biopharmaceutical customer companiondiagnostic development programs initiated in 2017 under our Governing Agreement with QML, which costs are included in research and developmentexpense in our statements of operations as the contracts are accounted for under the FASB’s guidance for collaborative arrangements. The increase incollaborative development program expenses in 2017 was partially offset by lower development costs incurred in 2017 for Project JANUS, which wassuspended in the third quarter of 2016. We expect research and development costs to continue to increase in 2018 due to the continuation of our existingcollaborative development programs, the addition of a third63collaborative development program in January 2018 and the remaining costs expected to be incurred as we approach the fourth and final module submissionof our HTG EdgeSeq ALKPlus Assay to the FDA.Selling, general and administrative expensesSelling, general and administrative expenses consist primarily of personnel costs for our sales and marketing, regulatory, legal, executive managementand finance and accounting functions. The expenses also include third-party professional and consulting fees incurred by these functions, promotionalexpenses and facility and overhead costs for our administrative offices. Selling, general and administrative expenses remained consistent for the year endedDecember 31, 2017 compared with the year ended December 31, 2016.Interest expenseAs of December 31, 2017, we had an obligation due to NuvoGen in the amount of $8.0 million under an asset purchase agreement, a Growth TermLoan obligation of $5.8 million, net of discount and deferred financing costs and a $3.0 million convertible debt liability to QNAH. Interest expense andnon-cash interest expense recognized for discount, deferred financing fee amortization and final fee premium amounts relating to these obligations decreasedby $0.6 million for the year ended December 31, 2017 as compared with the year ended December 31, 2016. The year over year decrease was primarily theresult of decreased interest incurred on the Growth Term Loan and NuvoGen obligations as the principal balances outstanding were reduced throughpayments made on these obligations throughout 2017.Cash Flows for the Years Ended December 31, 2017 and 2016The following table summarizes the primary sources and uses of cash for each of the periods presented: Years Ended December 31, 2017 2016 Net cash provided by (used in): Operating activities $(16,572,308) $(22,234,208)Investing activities 3,279,469 24,422,214 Financing activities 15,753,780 2,025,670 Increase in cash and cash equivalents $2,460,941 $4,213,676 Operating ActivitiesNet cash used in operating activities for the year ended December 31, 2017 was $16.6 million and reflected (i) the net loss of $19.0 million, (ii) netnon-cash items of $3.6 million, consisting primarily of stock-based compensation of $1.4 million, depreciation and amortization of $1.2 million, provisionfor excess inventory of $0.4 million, amortization of the discount, deferred financing costs and final payment premium on our Growth Term Loan of $0.4million and amortization of the discount on our NuvoGen obligation of $0.2 million, and (iii) a net cash outflow from changes in balances of operating assetsand liabilities of $1.2 million. This net cash outflow was due to an increase in accounts receivable attributable to our collaborative development servicesrevenue partially offset by an increase in accrued liabilities primarily related to the accrual for our annual performance-based bonuses. The primary driver ofthe cash outflow from changes in balances of operating assets and liabilities was the increase in activities under SOW One and SOW Two of our QMLGoverning Agreement in the fourth quarter of 2017, which resulted in a significant increase in accounts receivable for monthly development fees and profitsharing payments receivable at year end for both programs.Net cash used in operating activities for the year ended December 31, 2016 was $22.2 million and reflected (i) the net loss of $26.0 million, (ii) netnon-cash items of $4.1 million, consisting primarily of depreciation and amortization of $1.5 million, amortization of the discount on our NuvoGenobligation of $0.2 million, amortization of the discount, deferred financing costs and final payment premium on our Growth Term Loan of $0.6 million,provision for excess inventory of $0.7 million, stock-based compensation of $0.9 million and accrued interest on available-for-sale securities of $0.2 millionand (iii) a net cash outflow from changes in balances of operating assets and liabilities of $0.3 million. The significant items comprising the changes inbalances of operating assets and liabilities were an increase of $0.7 million in accounts receivable and an increase in deferred revenue of $0.3 million dueprimarily to up-front payments received from development agreements entered into in 2016.64Investing ActivitiesNet cash provided by investing activities of $3.3 million for the year ended December 31, 2017 consisted primarily of sales, redemptions andmaturities of $4.3 million of our remaining available-for-sale securities. This was partially offset by investments in laboratory sample processing andautomation equipment of $1.0 million.Net cash provided by investing activities of $24.4 million for the year ended December 31, 2016 consisted primarily of the purchase of $3.4 millionand sales, redemptions and maturities of $29.8 million of available-for-sale securities originally acquired with proceeds from our initial public offering. Thiswas partially offset by investments in leasehold improvements and laboratory equipment of $1.9 million with capital improvements made to ourmanufacturing and research and development facilities during the year.Financing ActivitiesNet cash provided by financing activities for the year ended December 31, 2017 of $15.8 million consisted primarily of $19.9 million in net proceedsfrom our ATM Offering and $3.0 million of proceeds from the QNAH Convertible Note, partially offset by $6.4 million in payments on our Growth TermLoan balance and $0.8 million in quarterly payments made on our NuvoGen obligation.Net cash provided by financing activities for the year ended December 31, 2016 of $2.0 million included $5.0 million from the draw of our Term LoanB availability in March 2016 to fund ongoing business operations and $2.0 million in proceeds from an investment in our common stock by a strategicinvestor, partially offset by $4.4 million in payments on our Growth Term Loan balance, as principal payments resumed in April 2016, and $0.6 million inquarterly payments made on our NuvoGen obligation.Liquidity and Capital ResourcesSince our inception, our operations have primarily been financed through the issuance of our common stock, redeemable convertible preferred stock,the incurrence of debt, cash received from product, service and collaborative development services revenue and other income. As of December 31, 2017, wehad $10.0 million of cash and cash equivalents and $16.9 million of debt outstanding on our Growth Term Loan, NuvoGen, capital lease and QNAHConvertible Note obligations.In August 2014, we entered into a Growth Term Loan with Oxford Finance, LLC and Silicon Valley Bank (see Note 8). We borrowed the first trancheof the Growth Term Loan in the amount of $11.0 million in August 2014 and the second tranche of the Growth Term Loan in the amount of $5.0 million inMarch 2016. The first and second tranches of the Growth Term Loan accrue interest annually at 8.5% and 8.75%, respectively, and mature on September 1,2018. Payments under the Growth Term Loan could result in a significant reduction of our working capital.Pursuant to our Controlled Equity Offering Sales Agreement with Cantor, we offered and sold, through Cantor as our sales agent, 5,733,314 shares ofour common stock for gross total proceeds of approximately $21.1 million through January 2018, under our Registration Statement on Form S-3 (File No.333-216977) and a prospectus supplement thereunder, as amended. All shares of common stock pursuant to the agreement with Cantor were made by amethod deemed to be an “at the market offering” as defined in Rule 415 under the Securities Act.Pursuant to an underwriting agreement with Leerink Partners LLC and Cantor, as representatives of the other underwriters of the agreement, we offeredand sold 13,915,000 shares of our common stock at a price of $2.90 per share, including 1,815,000 shares sold pursuant to the exercise in full of theunderwriters’ option to purchase additional shares in January 2018. The aggregate net proceeds from the offering were approximately $37.7 million, afterdeducting the underwriting discounts and commissions and offering expenses. The shares of common stock described above were offered by the Companypursuant to a Registration Statement on Form S-3 (File No. 333‑216977) previously filed with the SEC and declared effective by the SEC on April 6, 2017,and a prospectus supplement thereunder.Funding RequirementsWe have had recurring operating losses and negative cash flows from operations since inception, and we had an accumulated deficit of approximately$134.6 million as of December 31, 2017. As of December 31, 2017, we had available cash and cash equivalents of approximately $10.0 million, and hadcurrent liabilities of approximately $13.3 million plus an additional $11.0 million in long-term liabilities primarily attributable to our Growth Term Loan,NuvoGen obligation and QNAH Convertible Note. Including additional funding generated from our public offering in January 2018, we believe that ourexisting resources will be sufficient to fund our planned operations for at least the next 12 months from the issuance of these financial statements. However,we cannot provide assurances that our plans will not change or that changed circumstances will not result in the depletion of our capital resources morerapidly than we currently anticipate.65Until our revenue reaches a level sufficient to support self-sustaining cash flows, if ever, we may need to raise additional capital to fund our continuedoperations, including our product development and commercialization activities related to our current and future products. Future funding requirements willdepend on a number of factors, including our ability to generate significant revenue, our ability to repay our debt obligations as they become due, the costand timing of establishing additional sales, marketing and distribution capabilities, the ongoing cost of research and development activities, the cost andtiming of regulatory clearances and approvals, the effect of competing technology and market developments, the nature and timing of companion diagnosticdevelopment collaborations we may establish and the successful commercialization of clinical diagnostic products developed and approved as a result ofsuch collaborations and the extent to which we acquire or invest in businesses, products and technologies.Additional capital may not be available at such times or in amounts needed by us. Even if sufficient capital is available to us, it might be availableonly on unfavorable terms. If we are unable to raise additional capital in the future when required and in sufficient amounts or on terms acceptable to us, wemay have to delay, scale back or discontinue one or more product development programs, curtail our commercialization activities, significantly reduceexpenses, sell assets (potentially at a discount to their fair value or carrying value), enter into relationships with third parties to develop or commercializeproducts or technologies that we otherwise would have sought to develop or commercialize independently, cease operations altogether, pursue anacquisition of our company at a price that may result in up to a total loss on investment to our stockholders, file for bankruptcy, seek other protection fromcreditors, or liquidate all of our assets.Contractual ObligationsThe following table summarizes our contractual obligation as of December 31, 2017: Payments due by Period Total Less Than1 Year 1 - 3Years 3 - 5Years More Than5 Years Debt obligations (1) $17,279,133 $6,510,143 $4,470,247 $1,200,000 $5,098,743 Operating lease obligations (2) 1,628,578 527,269 1,101,309 — — Capital lease obligations (3) 82,820 58,460 24,360 — — Total contractual obligations $18,990,531 $7,095,872 $5,595,916 $1,200,000 $5,098,743 (1)Our debt obligations include amounts due to NuvoGen under an asset purchase agreement and, beginning in 2018, includes 2.5% interest on the then-remaining obligation. Beginning in 2018, we are obligated to pay the greater of $400,000 or 6% of sales until the obligation is paid in full. The tablereflects remaining minimum principal payments due to NuvoGen on the remaining obligation at December 31, 2017, although actual payments couldbe significantly more than provided in the table to the extent that 6% of revenue exceeds $400,000. Our debt obligations further include ourremaining contractual obligations pursuant to the Growth Term Loan with Oxford Finance LLC and Silicon Valley Bank entered into in 2014 andamended in 2015 and 2016. The table above includes contractual interest payments and a final premium fee relating to this loan. Refer to Note 8 ofour audited financial statements in Item 8 for payments due under the Growth Term Loan. The QNAH Convertible Note is also included in our debtobligations as of December 31, 2017. The table reflects the principal balance on the QNAH Convertible Note of $3,000,000 and interest at 3.0% perannum assuming that the balance will be paid upon maturity in October 2020 and not previously converted by QNAH into shares of our commonstock prior to maturity.(2)Our operating lease obligations consist of the leases for our laboratory and office facilities in Tucson, AZ expiring in 2021, as well as office copierleases.(3)Our capital lease obligations consist of several computer equipment leases which were entered into on various dates between December 2012 andDecember 2017.Off-Balance Sheet ArrangementsWe have not entered into any off-balance sheet arrangements.Recent Accounting PronouncementsFor a summary of recent accounting pronouncements applicable to our financial statements see “Note 2. Basis of Presentation and Summary ofSignificant Accounting Policies” in Part II, Item 8, Notes to Financial Statements, which is incorporated herein by reference.66Critical Accounting Policies and Significant Judgments and EstimatesOur management’s discussion and analysis of our financial condition and results of operation is based on our financial statements, which have beenprepared in accordance with U.S. GAAP. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statementsand the reported amounts of revenue and expenses during the reporting period. Items subject to estimates based on judgments include, but are not limited to:revenue recognition, stock-based compensation expense, fair value measurements, the resolution of uncertain tax positions, income tax valuation allowances,recovery of long-lived assets and provisions for doubtful accounts, inventory obsolescence and inventory valuation. Actual results could differ from theseestimates and such differences could affect the results of operations in future periods.Revenue RecognitionWe recognize revenue from the sale of instruments, consumables, sample processing, custom RUO assay development and collaborative developmentservices when the following four basic criteria are met: (1) a contract has been entered into with a customer or persuasive evidence of an arrangement exists,(2) delivery has occurred or services rendered, (3) the fee is fixed or determinable, and (4) collectability is reasonably assured.We account for contracts which combine one or more services, or services with sales of products or consumables as multiple element arrangementsunder ASC 605-25, as described under product and product-related services revenue below. Anticipated losses, if any, on contracts are charged to earnings assoon as they are identified. Anticipated losses cover all costs allocable to contracts. Revenue arising from claims or change orders is recorded either asincome or as an offset against a potential loss only when the amount of the claim can be estimated and its realization is probable.Product and Product-related Services RevenueSale of instruments and consumablesInstrument product revenue is generally recognized upon installation and calibration of the instrument by our field service engineers, unless thecustomer has specified any other acceptance criteria. The sale of instruments and related installation and calibration are considered to be one unit ofaccounting, as instruments are required to be professionally installed and calibrated before use. Installation generally occurs within a month of shipment.Consumables are considered to be separate units of accounting as they are sold separately. Consumables revenue is recognized upon transfer ofownership. Our standard terms and conditions provide that no right of return exists for instruments or consumables unless replacement is necessary due todelivery of defective or damaged products.When a contract involves multiple elements, the items included in the arrangement, referred to as deliverables, are evaluated to determine whetherthey represent separate units of accounting in accordance with ASC 605-25, Revenue Recognition – Multiple-Element Arrangements (“ASC 605-25”). Weperform this evaluation at the inception of an arrangement and as each item is delivered in the arrangement. Generally, we account for a deliverable (or agroup of deliverables) separately if the delivered item has stand-alone value to the customer and delivery or performance of the undelivered item or service isprobable and substantially in our control. When multiple elements can be separated into separate units of accounting, arrangement consideration is allocatedat the inception of the arrangement, based on each deliverables’ relative selling price. All revenue from contracts determined not to have separate units ofaccounting is recognized based on consideration of the most substantive delivery factor of all the elements in the contract.We provide instruments to customers under reagent rental agreements. Under these agreements, we install instruments in the customer’s facilitywithout a fee and the customer agrees to purchase consumable products at a stated price over the term of the agreement. We have included a minimumpurchase requirement in all of our existing reagent rental agreements and will continue to do so on future agreements. Terms range from several months tomultiple years and may automatically renew in several month or multiple year increments unless either party notifies the other in advance that the agreementwill not renew. This represents a multiple element arrangement and because all consideration under the reagent rental agreement is contingent on the sale ofconsumables, no consideration is allocated to the instrument and no revenue is recognized upon installation of the instrument. The cost of the instrumentunder the agreement is expected to be recovered in the fees charged for consumables, to the extent sold, over the term of the agreement. We retain title to the instrument in reagent rental agreements and such title is transferred to the customer at no additional charge at the conclusion ofthe initial arrangement. Because the pattern of revenue from the arrangement cannot be reasonably estimated, the cost of the instrument is amortized on astraight-line basis over the term of the arrangement, unless there is no minimum consumable product purchase in which case the instrument would beexpensed as cost of revenue. Cost to maintain the equipment while title remains with us is charged to cost of sales as incurred.67Service revenueCustom RUO Assay DevelopmentWe enter into custom RUO assay development agreements that may generate up-front fees and subsequent payments which might be earned uponcompletion of design process phases. We are able to estimate the total cost of services under these arrangements and recognize revenue using a proportionalperformance revenue recognition model, under which revenue is recognized as performance occurs based on the delivery of the relative outputs under therespective agreement. Costs incurred to date compared to total expected costs is used to determine proportional performance, as this is considered to berepresentative of the delivery of outputs under the arrangements. Revenue recognized at any point in time is limited to cash that we have received andamounts contractually due. Changes in estimates of total expected costs are accounted for prospectively as a change in estimate.Sample Processing ServicesOur VERI/O laboratory also provides sample processing services for our customers, whereby the customer provides samples to be processed using ourHTG EdgeSeq technology. Customers are charged a per sample fee for sample processing services which is recognized as revenue upon delivery of a data fileto the customer showing the results of testing, and completing delivery of the agreed upon service.Collaborative Development ServicesWe follow ASC 605-25, Revenue Recognition – Multiple-Element Arrangements and ASC 808, Collaborative Arrangements to determine theappropriate recognition of revenue under our collaborative research, development and commercialization agreements that contain multiple elements. Thesemultiple elements, or deliverables, may include access to our technology through grants of licenses to its intellectual property, research and developmentservices and participation in joint development steering committees, amongst others. The payments we receive under these arrangements typically includeone or more of the following: non-refundable up-front fees, monthly development service fees, milestone payments upon acceptance of contract deliverablesor profit sharing payments for completed contract milestones. From period to period, collaborative development services revenue can fluctuate significantlybased on the achievement of development-related milestones and the timing and number of development-related milestones in the project plan.Fair Value MeasurementsWe establish the fair value of all of our financial assets and liabilities, which are recognized and disclosed at fair value in the financial statements,using the price that would be received to sell an asset or paid to transfer a financial liability in an orderly transaction between market participants at themeasurement date. A fair value hierarchy is used to measure fair value. The three levels of the fair value hierarchy are as follows: Level 1 – Quoted prices in active markets for identical assets and liabilities.Level 2 – Pricing inputs are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments inmarkets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable andinclude situations where there is little, if any, market activity for the investment.Our portfolio of securities comprises U.S. Treasuries, U.S. government sponsored agency obligations and high credit quality corporate debt securitiesclassified as available-for-sale securities.Inventory ValuationInventory consists of raw materials and finished goods which are stated at the lower of cost (first-in, first-out) or net realizable value. We reserve orwrite down inventory for estimated obsolescence, inventory in excess of reasonably expected near term sales or unmarketable inventory, in an amount equalto the difference between the cost of inventory and the estimated market value, based upon assumption about future demand and market conditions. If actualmarket conditions are less favorable than those projected, additional inventory adjustments may be required. Inventory impairment charges establish a newcost basis for inventory and charges are not reversed subsequently to income, even if circumstances later suggest that increased carrying amounts arerecoverable.68Stock-Based CompensationWe recognize compensation costs related to stock-based payments to employees, including grants under our equity incentive plans of stock optionsand restricted stock units (“RSUs”) and stock purchase rights granted under our ESPP, based on the estimated fair value of the awards on the date of grant.The fair value of RSUs is based on the quoted market price of our common stock on the date of grant. With the adoption of guidance in ASU No. 2016-09effective January 1, 2017, we elected to change our policy surrounding forfeitures such that we no longer estimate the number of awards expected to beforfeited but instead we account for them as they occur. The fair value of ESPP rights and stock options granted pursuant to our equity incentive plans isestimated on the date of grant using the Black-Scholes option pricing model. The determination of the fair value using the Black-Scholes option pricingmodel is affected by the fair value of our common stock and several assumptions, including volatility, expected term, risk-free interest rate and dividendyield. Generally, these assumptions are based on historical information and judgment is required to determine if historical trends may be indicators of futureoutcomes. These estimates involve inherent uncertainties. Changes to the assumptions that we have used in the Black-Sholes option pricing model couldsignificantly impact the compensation expense that has been recognized in our statements of operations. If we had made different assumptions, our stock-based compensation expense, net loss and net loss per share of common stock could have been significantly different.Income TaxesWe account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequencesattributable to the differences between the financial statement carrying amounts and tax base of assets and liabilities using enacted tax rates and laws that willbe in effect when the differences are expected to reverse. A valuation allowance is established against net deferred tax assets for the uncertainty it presents ofour ability to use the net deferred tax assets, in this case, primarily carryforwards of net operating tax losses and research and development tax credits. Inassessing the realizability of net deferred tax assets we have assessed the likelihood that net deferred tax assets will be recovered from future taxable income,and to the extent that recovery is not “more likely than not” or there is an insufficient history of operating profits, a valuation allowance is established. Werecord the valuation allowance in the period we determine that it is not more likely than not that net deferred tax assets will be realized. For the years endedDecember 31, 2017 and 2016, we have provided a full valuation allowance for all net deferred tax assets due to their current realization being consideredremote in the near term. Uncertain tax positions taken or expected to be taken in a tax return are accounted for using the more likely than not threshold forfinancial statement recognition and measurement. The 2017 Tax Act, which was signed into law on December 22, 2017, significantly revises the IRC. Forfurther information as to its impact on our financial statements see “Note 14. Income Taxes” in Part II, Item 8, Notes to Financial Statements.Emerging Growth Company StatusWe are an emerging growth company as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerginggrowth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as thosestandards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and,therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. Item 7A. Quantitative and Qualitative Disclosures About Market Risk.We are exposed to market risks in the ordinary course of our business. These risks primarily relate to interest rates. We had cash and cash equivalentsof $10.0 million at December 31, 2017, which consist of bank deposits and money market funds. Such interest-bearing instruments carry a degree of risk;however, we have not been exposed to, nor do we anticipate being exposed to, material risks due to changes in interest rates. Our debt is at fixed interest rates.A hypothetical 10% change in interest rates during any of the periods presented would not have had a material impact on our financial statements.As we continue to expand internationally our results of operations and cash flows will become increasingly subject to fluctuations due to changes inforeign currency exchange rates. Historically, a majority of our revenue has been denominated in U.S. dollars, although we sell our products and servicesdirectly in certain markets outside of the United States denominated in local currency, principally the Euro. Our expenses are generally denominated in thecurrencies in which our operations are located, which is primarily in the United States. The effect of a 10% adverse change in exchange rates on foreigndenominated receivables and payables would not have had a material impact on our results of operations during the periods presented. As our operations incountries outside of the United States grow, our results of operations and cash flows will be subject to potentially greater fluctuations due to changes inforeign currency exchange rates, which could increasingly affect our operating results. To date, we have not entered into any foreign currency hedgingcontracts, although we may do so in the future.Item 8.

F-7HTG Molecular Diagnostics, Inc.Notes to Financial Statements Note 1. Description of BusinessHTG Molecular Diagnostics, Inc. (the “Company”) is a provider of instruments, reagents and services for molecular profiling applications. The Companyderives revenue from sales of its HTG EdgeSeq automation system and integrated next-generation sequencing-based HTG EdgeSeq assays, from servicesincluding sample processing and custom research use only (“RUO”) assay development and from collaborative development services.The Company operates in one segment and its customers are located primarily in the United States and Europe. For the year ended December 31, 2017,approximately 67% of the Company’s revenue was generated from sales originated by customers located outside of the United States, compared with 16% forthe year ended December 31, 2016. The increase in sales to customers located outside of the United States is primarily the result of collaborativedevelopment services revenue generated from the Master Assay Development, Commercialization and Manufacturing Agreement (the “GoverningAgreement”), with QIAGEN Manchester Limited (“QML”), a wholly owned subsidiary of QIAGEN N.V. (See Note 15), which accounted for 80% of sales tocustomers located outside of the United States. Note 2. Basis of Presentation and Summary of Significant Accounting PoliciesAccounting PrinciplesThe financial statements and accompanying notes were prepared in accordance with accounting principles generally accepted in the United States of America(“U.S. GAAP”).ReclassificationsCertain prior year amounts have been reclassified for consistency with the current period presentation. These reclassifications had no effect on the reportedresults of operations.Going Concern and LiquidityThe Company implemented the criteria of Accounting Standards Update (“ASU”) No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability toContinue as a Going Concern, in the first quarter of 2016. In accordance with this guidance, management has assessed the Company’s ability to continue as agoing concern within one year of the filing date of this Annual Report on Form 10‑K with the Securities and Exchange Commission (“SEC”). Theaccompanying financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates the realization ofassets and satisfaction of liabilities in the normal course of business. The Company has had recurring operating losses and negative cash flows fromoperations since its inception and has an accumulated deficit of approximately $134.6 million. As of December 31, 2017, the Company had available cashand cash equivalents of approximately $10.0 million, and had current liabilities of approximately $13.3 million plus an additional $11.0 million in long-term liabilities. The Company’s liability balance is primarily attributable to its asset-secured growth capital term loan with Oxford Finance, LLC and SiliconValley Bank (the “Growth Term Loan”), an obligation to NuvoGen Research, LLC (“NuvoGen”) and a subordinated convertible promissory note withQIAGEN North American Holdings, Inc. (the “QNAH Convertible Note”). Although the Company believed that the circumstances existing as of December31, 2017 gave rise to substantial doubt about the Company’s ability to continue as a going concern, the Company successfully completed an underwrittenpublic offering of 13,915,000 shares of its common stock at a price of $2.90 per share on January 23, 2018 (see Note 16). The aggregate net proceeds from theoffering were approximately $37.7 million, after deducting underwriting discounts and commissions and offering expenses. After consideration of the netproceeds received in the offering, the Company believes that the substantial doubt that existed as of December 31, 2017 has been alleviated and there is nolonger substantial doubt about the Company’s ability to continue as a going concern for at least the next 12 months from the issuance of the financialstatements included in this Annual Report on Form 10-K.Recently Adopted Accounting PronouncementsIn July 2015, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2015-11, Inventory: Simplifying the Measurement of Inventory. Thestandard requires inventory within the scope of the ASU to be measured using the lower of cost and net realizable value. The changes apply to all types ofinventory, except those measured using last-in, first-out (“LIFO”) method or the retail inventory method, and are intended to more clearly articulate therequirements for the measurement and disclosure of inventory and to simplify the accounting for inventory by eliminating the notions of replacement costand net realizable value less a normal profit margin. The standard was effective for fiscal years and interim periods within those fiscal years beginning afterDecember 15, 2016. The Company adopted this guidance effective January 1, 2017. The Company previously measured its inventory at the lower of cost ormarket with cost being determined by the first-in, first-out (“FIFO”) method. The adoption of the guidance did not have a material impact on the Company’sfinancial statements.F-8In April 2016, the FASB issued ASU No. 2016-09, Share-Based Payment: Simplifying the Accounting for Share-Based Payments. The standard addressesseveral aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures and statutory taxwithholding requirements, as well as classification in the statement of cash flows. The new standard was effective for fiscal years and interim periods withinthose fiscal years beginning after December 15, 2016. The Company adopted this guidance effective January 1, 2017. Excess tax benefits recorded uponadoption of this standard are not material to the balance sheets. The elimination of the APIC pool affects the treasury stock method used to calculateweighted average shares outstanding; however, the impact of this change was not material. The Company elected to change its policy concerning potentialforfeitures of employee share-based awards, and beginning January 1, 2017, the Company no longer estimates the number of awards expected to be forfeitedbut instead accounts for forfeitures as they occur. The Company implemented this portion of the guidance using a modified retrospective approach. Thecumulative adjustment was not material to additional paid-in capital. Other provisions of ASU 2016‑09 had no impact on the Company’s financialstatements.Use of EstimatesThe preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reportedamounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts ofrevenues and expenses during the reporting period. The Company’s significant estimates include revenue recognition, stock-based compensation expense,bonus accrual, income tax valuation allowances, recovery of long‑lived assets, inventory obsolescence and inventory valuation. Actual results couldmaterially differ from those estimates.Cash and Cash EquivalentsThe Company considers all highly liquid investments with an original maturity of three months or less to be cash and cash equivalents. Cash and cashequivalents consist of cash on deposit with financial institutions, money market instruments and high credit quality corporate debt securities purchased witha term of three months or less.Accounts ReceivableAccounts receivable represent valid claims against debtors. Management reviews accounts receivable regularly to determine, using the specific identificationmethod, if any receivable amounts will potentially be uncollectible and to estimate the amount of allowance for doubtful accounts necessary to reduceaccounts receivable to its estimated net realizable value. There were no receivable amounts requiring an allowance for doubtful accounts as of December 31,2017 or December 31, 2016.InvestmentsThe Company classifies its debt securities as available-for-sale, which are reported at estimated fair value with unrealized gains and losses included inaccumulated other comprehensive loss, net of tax. Realized gains, realized losses and declines in value of securities judged to be other-than-temporary, areincluded in other income (expense) within the accompanying statements of operations. The cost of investments for purposes of computing realized andunrealized gains and losses is based on the specific identification method. Interest earned on all securities is included in other income (expense) within theaccompanying statements of operations. Investments in securities with maturities of less than one year, or where management’s intent is to use theinvestments to fund current operations, or to make them available for current operations, are classified as short-term investments.If the estimated fair value of a security is below its carrying value, the Company evaluates whether it is more likely than not that it will sell the security beforeits anticipated recovery in market value and whether evidence indicating that the cost of the investment is recoverable within a reasonable period of timeoutweighs evidence to the contrary. The Company also evaluates whether or not it intends to sell the investment. If the impairment is considered to be other-than-temporary, the security is written down to its estimated fair value. In addition, the Company considers whether credit losses exist for any securities. Acredit loss exists if the present value of cash flows expected to be collected is less than the amortized cost basis of the security. Other-than-temporary declinesin estimated fair value and credit losses are charged against other income (expense).F-9Fair Value of Financial InstrumentsFair value measurements are based on the premise that fair value is an exit price representing the amount that would be received to sell an asset or paid totransfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined basedon assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the following three-tier fairvalue hierarchy has been used in determining the inputs used in measuring fair value: Level 1 – Quoted prices in active markets for identical assets or liabilities on the reporting date. Level 2 – Pricing inputs are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments inmarkets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market orcan be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 – Pricing inputs are generally unobservable and include situations where there is little, if any, market activity for the investment. Theinputs into the determination of fair value require management’s judgment or estimation of assumptions that market participants woulduse in pricing the assets or liabilities. The fair values are therefore determined using factors that involve considerable judgment andinterpretations, including but not limited to private and public comparables, third-party appraisals, discounted cash flow models, andfund manager estimates. The carrying value of financial instruments classified as current assets and current liabilities approximate fair value due to their liquidity and short-termnature. Investments that are classified as available-for-sale are recorded at fair value, which was determined using quoted market prices, broker or dealerquotations, or alternative pricing sources with reasonable levels of price transparency. The QNAH Convertible Note is an obligation to a greater than 5%common stockholder of the Company (see Note 15). As of December 31, 2017, the estimated aggregate fair value of the QNAH Convertible Noteis approximately $2.8 million. The fair value estimate is based on the note’s discounted cash flows and estimated option value of the conversion terms. Theestimated fair value of the QNAH Convertible Note represents a Level 3 measurement. The NuvoGen obligation is an obligation relating to an asset purchasetransaction with a then-common stockholder of the Company. Although the obligation is considered a financial instrument, the Company is unable toreasonably determine its fair value as the remaining payments due under the obligation will be made at the greater of a minimum quarterly payment or 6% ofrevenue, causing variability in the timing and amount of payments and the term of the remaining obligation.Inventory, netInventory, consisting of raw materials, work in process and finished goods, is stated at the lower of cost (first-in, first-out) or net realizable value. Cost isdetermined using a standard cost system, whereby the standard costs are updated periodically to reflect current costs and net realizable value represents thelower of replacement cost or estimated net realizable value. The Company reserves or writes down its inventory for estimated obsolescence or inventory inexcess of reasonably expected near term sales or unmarketable inventory, in an amount equal to the difference between the cost of inventory and theestimated market value, based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than thoseprojected by the Company, additional inventory write-downs may be required. Inventory impairment charges establish a new cost basis for inventory andcharges are not reversed subsequently to income, even if circumstances later suggest that increased carrying amounts are recoverable. The reserve for shrinkage and excess inventory was 62,142 and $270,307 as of December 31, 2017 and 2016, respectively. Inventory of $208,112 and167,100 was written off directly to cost of revenue in the accompanying statements of operations for the years ended December 31, 2017 and 2016,respectively.Equipment that is under evaluation for purchase remains in inventory as the Company maintains title to the equipment throughout the evaluation period.The period of time customers use to evaluate the Company’s equipment generally ranges from 90 to 180 days, and in certain circumstances the evaluationperiod may need to be extended beyond that period. However, in no case will the evaluation period exceed one year. If the customer has not purchased theequipment or entered into a reagent rental agreement with the Company after evaluating the product for one year, the equipment is returned to the Companyor the customer is allowed to continue use of the equipment, in which case the equipment is written off to selling, general and administrative expense in theaccompanying statement of operations. HTG EdgeSeq instruments at customer locations under evaluation agreements are included in finished goodsinventory. Finished goods inventory under evaluation as of December 31, 2017 was $53,365 compared to $185,557 as of December 31, 2016.F-10Property and Equipment, netProperty and equipment are stated at historical cost and depreciated over their useful lives, which range from three to five years, using the straight-linemethod. Equipment used in the field is amortized using the straight-line method over the lesser of the period of the related reagent rental or collaborativedevelopment services agreement where applicable or the estimated useful life. Leasehold improvements are amortized using the straight-line method over thelesser of the remaining lease term or the estimated useful life.Certain leasehold improvements constructed by the landlord of the Company’s Tucson, AZ facilities as an incentive for the Company to extend its leases areincluded in leasehold improvements on the balance sheets as of December 31, 2017. The total cost of the improvements constructed by the landlord of$710,000 was capitalized when construction was completed in February 2016, and is being amortized over the remaining term of the lease agreement. Theincentive of $710,000 has been recognized as deferred rent within other current liabilities and other liabilities on the balance sheets and is being accretedover the lease term as a reduction of rent expense (see Note 13).Depreciation and leasehold improvement amortization expense was $1,241,873 for the year ended December 31, 2017, and $1,473,778 for the year endedDecember 31, 2016.Costs incurred in the development and installation of software for internal use and in the development of the Company’s website are expensed or capitalized,depending on whether they are incurred in the preliminary project stage (expensed), application development stage (capitalized), or post-implementationstage (expensed). Amounts capitalized following project completion are amortized on a straight-line basis over the useful life of the developed asset, which isgenerally three years.Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not berecoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset group to the estimated undiscountedfuture cash flows expected to be generated by the asset group. If the carrying amount of an asset group exceeds its estimated future cash flow, an impairmentcharge is recognized in the amount by which the carrying amount of the asset group exceeds the fair value of the asset group. Although the Company hasaccumulated losses since inception, the Company believes the future cash flows will be sufficient to exceed the carrying value of the Company’s long-livedassets. There were no impairments of long-lived assets during the years ended December 31, 2017 and 2016.Deferred Financing Costs and Debt DiscountsCertain costs incurred in connection with the Growth Term Loans and the QNAH Convertible Note have been deferred and are being amortized.Debt issuance costs and debt discount relating to the Growth Term Loans are being presented as a direct reduction of term loan payable – current, net ofdiscount and debt issuance costs as of December 31, 2017 and as a direct reduction of term loan payable – non-current, net of discount and debt issuancecosts as of December 31, 2016 in the accompanying balance sheets. Debt issuance costs and debt discount are being amortized over the term of the GrowthTerm Loans using the effective interest method. The Company has recorded approximately $6,269 and $24,909 of Growth Term Loans deferred financingcosts in the accompanying balance sheets as of December 31, 2017 and 2016, respectively. Deferred financing cost amortization expense relating to theGrowth Term Loans for the years ended December 31, 2017 and 2016 was $18,640 and $27,468, respectively, and is included in interest expense in theaccompanying statements of operations. The Company has recorded approximately $58,538 and $238,469 of discounts associated with Growth Term Loan Aand Growth Term Loan B in the accompanying balance sheets as of December 31, 2017 and 2016, respectively. Amortization of the discounts associated withthe Growth Term Loans totaled $179,931 and $249,868 for the years ended December 31, 2017 and 2016, and is included in interest expense in theaccompanying statements of operations.Debt issuance costs of $39,240 relating to the QNAH Convertible Note are being presented as a direct reduction of Convertible Note, related party – net ofdebt issuance costs as of December 31, 2017. There was no QNAH Convertible Note liability or related financing costs as of December 31, 2016. Deferredfinancing cost amortization relating to the QNAH Convertible Note for the years ended December 31, 2017 and 2016 was $1,269 and $0, respectively, and isincluded in interest expense in the accompanying statements of operations.Deferred Offering CostsDeferred offering costs represent legal and other direct costs related to stock offering transactions. Deferred offering costs of $2,953 included as current assetsin the accompanying balance sheets as of December 31, 2017 represent legal costs incurred during the year ended December 31, 2017 by the Company incontemplation of the issuance of additional shares in a future financing transaction. There were deferred offering costs of $49,630 included in theaccompanying balance sheets as of December 31, 2016.F-11Deferred RevenueDeferred revenue represents cash receipts for products or services to be provided in future periods, including up-front fees received relating to custom RUOassay development and sample processing services and collaboration development services. When products are delivered or data is provided to customers forsample processing services rendered, deferred revenue is recognized as earned. Up-front fees received for custom RUO assay development and collaborativedevelopment services are recognized as development procedures are completed and outputs are produced on a proportional performance basis.Revenue RecognitionThe Company recognizes revenue from the sale of instruments, consumables, sample processing, custom RUO assay development and collaboration serviceswhen the following four basic criteria are met: (1) a contract has been entered into with a customer or persuasive evidence of an arrangement exists, (2)delivery has occurred or services rendered, (3) the fee is fixed or determinable, and (4) collectability is reasonably assured.Contracts which combine one or more services, or services with sales of products or consumables are accounted for as multiple element arrangements underASC 605-25, as described under product and product-related services revenue below. Anticipated losses, if any, on contracts are charged to earnings as soonas they are identified. Anticipated losses cover all costs allocable to contracts. Revenue arising from claims or change orders is recorded either as income or asan offset against a potential loss only when the amount of the claim can be estimated and its realization is probable.Product and Product-related Services RevenueThe Company had product and product-related services revenue consisting of revenue from the sale of instruments and consumables and the use of theHTG EdgeSeq proprietary technology to process samples and develop custom RUO assays for the years ended December 31, 2017 and 2016 as follows: Years Ended December 31, 2017 2016 Product revenue: Instruments $385,143 $522,813 Consumables 1,463,347 2,237,129 Total product revenue 1,848,490 2,759,942 Product-related services revenue: Custom RUO assay development 419,515 235,818 Sample processing 4,529,250 2,136,970 Total product-related services revenue 4,948,765 2,372,788 Total product and product-related services revenue $6,797,255 $5,132,730 Sale of instruments and consumablesInstrument product revenue is generally recognized upon installation and calibration of the instrument by field service engineers, unless the customer hasspecified any other acceptance criteria. The sale of instruments and related installation and calibration are considered to be one unit of accounting, asinstruments are required to be professionally installed and calibrated before use. Installation generally occurs within one month of shipment.Consumables are considered to be separate units of accounting as they are sold separately from instruments. Consumables revenue is recognized upontransfer of ownership. The Company’s standard terms and conditions provide that no right of return exists for instruments or consumables, unless replacementis necessary due to delivery of defective or damaged products. Shipping and handling fees charged to the Company’s customers for instruments andconsumables shipped are included in the accompanying statements of operations as part of product and product-related service revenue. Shipping andhandling costs for sold products shipped to the Company’s customers are included on the accompanying statements of operations as part of cost of revenue.When a contract involves multiple elements, the items included in the arrangement, referred to as deliverables, are evaluated to determine whether theyrepresent separate units of accounting in accordance with ASC 605-25, Revenue Recognition – Multiple-Element Arrangements (“ASC 605-25”). TheCompany performs this evaluation at the inception of an arrangement and as each item is delivered in the arrangement. Generally, the Company accounts fora deliverable (or a group of deliverables) separately if the delivered item has stand-alone value to the customer and delivery or performance of theundelivered item or service is probable and substantially in the Company’s control. When multiple elements can be separated into separate units ofaccounting, arrangement consideration is allocated at the inception of the arrangement, based on each unit’s relative selling price, and recognized based onthe method most appropriate for that unit.F-12The Company provides instruments to certain customers under reagent rental agreements. Under these agreements, the Company installs instruments in thecustomer’s facility without a fee and the customer agrees to purchase consumable products at a stated price over the term of the agreement; in some instances,the agreements do not contain a minimum purchase requirement. Terms range from several months to multiple years and may automatically renew in severalmonth or multiple year increments unless either party notifies the other in advance that the agreement will not renew. This represents a multiple elementarrangement and because all consideration under the reagent rental agreement is contingent on the sale of consumables, no consideration has been allocatedto the instrument and no revenue has been recognized upon installation of the instrument. The Company expects to recover the cost of the instrument underthe agreement through the fees charged for consumables, to the extent sold, over the term of the agreement.In reagent rental agreements, the Company retains title to the instrument and title is transferred to the customer at no additional charge at the conclusion ofthe initial arrangement. Because the pattern of revenue from the arrangement cannot be reasonably estimated, the cost of the instrument is amortized on astraight-line basis over the term of the arrangement, unless there is no minimum consumable product purchase in which case the instrument would beexpensed as cost of revenue. Cost to maintain the instrument while title remains with the Company is charged to selling, general and administrative expenseas incurred.The Company offers customers the opportunity to purchase separately-priced extended warranty contracts to provide for service upon conclusion of thestandard one-year warranty period. The revenue from these contracts is recorded as a component of deferred revenue in the balance sheets at the inception ofthe contract. Extended warranty product revenue is recognized over the contract service period as part of product and product-related services revenue on theaccompanying statements of operations.Service RevenueCustom RUO Assay DevelopmentThe Company enters into custom RUO assay development agreements that may generate up-front fees and subsequent payments which might be earned uponcompletion of design process phases. The Company is able to estimate the total cost of services under these arrangements and recognizes revenue using aproportional performance revenue recognition model, under which revenue is recognized as performance occurs based on the delivery of the relative outputsunder the respective agreement. Costs incurred to date compared to total expected costs are used to determine proportional performance, as this is consideredto be representative of the delivery of outputs under the arrangements. Revenue recognized at any point in time is limited to cash received and amountscontractually due. Changes in estimates of total expected costs are accounted for prospectively as a change in estimate. From period to period, custom RUOassay development revenue can fluctuate substantially based on the completion of development-related phases.Sample Processing ServicesThe Company also provides sample processing services and molecular profiling of retrospective cohorts for its customers through its VERI/O laboratory,whereby the customer provides samples to be processed using HTG EdgeSeq technology specified in the order. Customers are charged a per sample fee forsample processing services which is recognized as revenue upon delivery of a data file to the customer showing the results of testing, and completingdelivery of the agreed upon service.Collaborative Development ServicesThe Company follows ASC 605-25, Revenue Recognition – Multiple-Element Arrangements and ASC 808, Collaborative Arrangements to determine theappropriate recognition of revenue for its collaborative development services. Collaborative development services revenue includes services performed bythe Company on biopharmaceutical company companion diagnostic development programs using its HTG EdgeSeq proprietary technology to develop, seekregulatory approval for and commercialize companion diagnostics for biopharmaceutical company drug candidates and corresponding therapeutics. Theseagreements often contain multiple elements, or deliverables, which may include access to the Company’s technology through grants of licenses to itsintellectual property, research and development services and participation in joint development steering committees, amongst others. The payments theCompany receives under these arrangements typically include one or more of the following: non-refundable up-front fees, monthly development service fees,milestone payments upon acceptance of contract deliverables or profit sharing payments for completed contract milestones. From period to period,collaborative development services revenue can fluctuate substantially based on the achievement of development-related milestones and the timing andnumber of development-related milestones in the project plan.F-13Product WarrantyThe Company generally provides a one-year warranty on its HTG EdgeSeq systems covering the performance of system hardware and software inconformance with customer specifications under normal use and protecting against defects in materials and workmanship. The Company may, at its option,replace, repair or exchange products covered under valid warranty claims. A provision for estimated warranty costs is recognized at the time of sale, throughcost of revenue, based upon recent historical experience and other relevant information as it becomes available. The Company continuously assesses theadequacy of its product warranty accrual by reviewing actual claims and adjusts the provision as needed.Research and Development ExpensesResearch and development expenses represent costs incurred internally for research and development activities and costs incurred externally to fund researchactivities. These costs include those generated through research and development efforts for the improvement and expansion of the Company’s proprietarytechnology and product offerings as well as those related to third-party collaborative development agreements, for which related revenue is included incollaborative development services revenue in the accompanying statements of operations.AdvertisingAll costs associated with advertising and promotions are expensed as incurred. Advertising expense was $245 and $49,022 for the years ended December 31,2017 and 2016, respectively, and is included as a component of selling, general and administrative expenses on the accompanying statements of operations.Stock-Based CompensationThe Company incurs stock-based compensation expense relating to grants under its equity incentive plans of restricted stock units (“RSUs”) and stockoptions to employees, consultants and non-employee directors, and stock purchase rights granted under its employee stock purchase plan (“ESPP”).The Company recognizes expense for stock-based awards to employees and non-employee directors based on the fair value of awards on the date of grant.The fair value of RSUs is based on the quoted market price of the Company’s common stock on the date of grant. The fair value of ESPP rights and stockoptions granted pursuant to the Company’s equity incentive plans is estimated on the date of grant using the Black-Scholes option pricing model. Thedetermination of the fair value utilizing the Black-Scholes option pricing model is affected by the fair value of the Company’s stock price and severalassumptions, including volatility, expected term, risk-free interest rate, and dividend yield. Generally, these assumptions are based on historical informationand judgment is required to determine if historical trends may be indicators of future outcomes.The Company elected to change its policy surrounding forfeitures of equity awards with the adoption of the guidance in ASU No. 2016-09 on January 1,2017. The Company no longer estimates the number of awards expected to be forfeited but instead accounts for such forfeitures as they occur. For stock-based awards to consultants, the fair value of the stock-based award is used to measure the transaction, as the Company believes this to be a morereliable measure of fair value than the services received. The fair value of each award is remeasured at each measurement date until performance by thenonemployee is complete. Stock-based compensation to nonemployees is recognized as expense over the requisite service period, which is generally thevesting period for awards, on a straight-line basis.Income TaxesThe Company accounts for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future taxconsequences attributable to the differences between the financial statement carrying amounts and tax base of assets and liabilities using enacted tax ratesand laws that will be in effect when the differences are expected to reverse. A valuation allowance is established against net deferred tax assets for theuncertainty it presents of the Company’s ability to use the net deferred tax assets, in this case, primarily carryforwards of net operating tax losses and researchand development tax credits. In assessing the realizability of net deferred tax assets the Company has assessed the likelihood that net deferred tax assets willbe recovered from future taxable income, and to the extent that recovery is not “more likely than not” or there is an insufficient history of operating profits, avaluation allowance is established. The Company records the valuation allowance in the period the Company determines that it is not more likely than notthat net deferred tax assets will be realized. For the years ended December 31, 2017 and 2016, the Company has provided a full valuation allowance for allnet deferred tax assets due to their current realization being considered remote in the near term. Uncertain tax positions taken or expected to be taken in a taxreturn are accounted for using the more likely than not threshold for financial statement recognition and measurement. The 2017 Tax Act, which was signedinto law on December 22, 2017, significantly revises the Internal Revenue Code of 1986, as amended (the “IRC”) (see Note 14).F-14Comprehensive lossComprehensive loss includes certain changes in equity that are excluded from net loss. Specifically, unrealized gains and losses on short and long-termavailable-for-sale investments are included in comprehensive loss.Concentration RisksFinancial instruments that potentially subject the Company to credit risk consist principally of cash and cash equivalents and accounts receivable. TheCompany maintains the majority of its cash balances in the form of cash deposits in bank checking and money market accounts in amounts in excess offederally insured limits. Management believes, based upon the quality of the financial institution, that the credit risk with regard to these deposits is notsignificant. The Company sells its instruments, consumables, sample processing services, custom RUO panel design and collaborative development services primarily tobiopharmaceutical companies, academic institutions and molecular labs. The Company routinely assesses the financial strength of its customers and creditlosses have been minimal to date. The top two customers accounted for 54% and 8% of the Company’s revenue for the year ended December 31, 2017, compared with 29% and 12% for theyear ended December 31, 2016. The largest two customers accounted for approximately 66% and 11% of the Company’s net accounts receivable as ofDecember 31, 2017. The largest of these amounts represents accounts receivable relating to work performed under two statements of work entered into underthe Company’s Governing Agreement with QML. The largest two customers accounted for approximately 28% and 15% of the Company’s net accountsreceivable at December 31, 2016.Three vendors accounted for 23%, 17% and 15% of the Company’s accounts payable as of December 31, 2017 primarily related to the Company’scollaborative development services programs. Two vendors accounted for 11% and 8% of the Company’s accounts payable at December 31, 2016.The Company currently relies on a single supplier to supply a subcomponent used in the HTG EdgeSeq processors. A loss of this supplier could significantlydelay the delivery of products, which in turn would materially affect the Company’s ability to generate revenue.New Accounting PronouncementsThe following are new FASB ASUs that had not been adopted by the Company as of December 31, 2017, and are grouped by their respective effective dates:January 1, 2018In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which supersedes nearly all existing revenuerecognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred tocustomers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five-stepprocess to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than arerequired under existing U.S. GAAP.In March 2016, the FASB issued ASU No. 2016-08, Revenue Recognition: Clarifying the new Revenue Standard’s Principal-Versus-Agent Guidance (“ASU2016-08”). The standard amends the principal-versus-agent implementation guidance and illustrations in ASU 2014-09. ASU 2016-08 clarifies that an entityshould evaluate whether it is the principal or the agent for each specified good or service promised in a contract with a customer. As defined in ASU 2016-08,a specified good or service is “a distinct good or service (or a distinct bundle of goods or services) to be provided to the customer.” Therefore, for contractsinvolving more than one specified good or service, the Company may be the principal in one or more specified goods or services and the agent for others.In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing.The amendments in this standard affect the guidance in ASU 2014-09 by clarifying two aspects: identifying performance obligations and the licensingimplementation guidance.In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow Scope Improvements and PracticalExpedients. The amendments in this standard affect the guidance in ASU 2014-09 by clarifying certain specific aspects of ASU 2014-09, includingassessment of collectability, treatment of sales taxes and contract modifications, and providing certain technical corrections.F-15The new revenue standard and the standards that amend it are effective for public entities for fiscal years and interim periods within those fiscal yearsbeginning after December 15, 2017, using either of the following transition methods: (i) a full retrospective approach reflecting the application of thestandard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect ofinitially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). The Company will adopt ASC 606using the full retrospective approach, which will not have an effect on 2017 or 2016 revenue recognition and will have no cumulative effect on openingequity, as the timing and measurement of revenue recognition will be materially the same as under ASC 605. The Company will present additionalquantitative and qualitative disclosures regarding identified revenue streams and performance obligations. We have identified and are implementing changesto our business processes and internal controls relating to implementation of the new standard. While the adoption of this guidance will not have a materialimpact on the Company’s financial statements, our disclosures will change to meet the requirements of this new guidance for the first quarter of 2018.In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments,(“ASU 2016-15”), which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice in how certain cash receiptsand cash payments are presented and classified in the statement of cash flows. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017,including interim periods within those fiscal years with early adoption permitted, including adoption in an interim period. The Company will adopt ASU No.2016-15 as of January 1, 2018. When considering the activity within the Company’s statements of cash flow as of the years ended December 31, 2017 and2016, the Company does not believe the adoption of this standard will have a significant impact on its financial statements.In May 2017, the FASB issued ASU No. 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting. The new standardprovides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting inTopic 718. The new standard is effective on January 1, 2018; however, early adoption was permitted. The Company will adopt ASU No. 2017-09 as ofJanuary 1, 2018. The adoption of this update is not expected to impact the Company’s financial statements.January 1, 2019In February 2016, the FASB issued ASU No. 2016-02, Leases, (“ASU 2016-02”). Under this standard, which applies to both lessors and lessees, lessees will berequired to recognize for all leases (except for short-term leases) a lease liability, which is a lessee’s obligation to make lease payments arising from a leasemeasured on a discounted basis, and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for thelease term. Leases will be classified as either financing or operating, with classification affecting the pattern of expense recognition in the income statement.The new standard is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2018. A modified retrospectivetransition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative periodpresented in the financial statements, with certain practical expedients available. The effect of adoption of this standard on our financial statements dependson the leases existing at January 1, 2018. Based on the Company’s office and equipment leases at that date and considering the practical expedients, theCompany expects that adoption of ASU 2016‑02 will not have a material effect on its statements of operations, will result in a gross-up on its balance sheetsof less than $2.0 million relating to office and equipment leases and will have no effect on its statements of cash flows. The Company will continue to assessthe new guidance and its potential applicability, to new agreements that it may enter into subsequent to January 1, 2018 through the date of adoption.In July 2017, the FASB issued ASU 2017-11, Accounting for Certain Financial Instruments with Down Round Features. The new standard makes limitedchanges to previous guidance on classifying certain financial instruments as either liabilities or equity. The new standard is effective for fiscal yearsbeginning after December 15, 2018, including interim periods within those fiscal years with early adoption permitted, including adoption in an interimperiod. When considering the Company’s existing financial instruments, the Company does not believe the adoption of this standard will have an effect onits financial statements.January 1, 2020In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses, which requires the measurement of expected credit losses forfinancial instruments carried at amortized cost held at the reporting date based on historical experience, current conditions and reasonable forecasts. Theupdated guidance also amends the current other-than-temporary impairment model for available-for-sale debt securities by requiring the recognition ofimpairments relating to credit losses through an allowance account and limits the amount of credit loss to the difference between a security’s amortized costbasis and its fair value. In addition, the length of time a security has been in an unrealized loss position will no longer impact the determination of whether acredit loss exists. The main objective of this ASU is to provide financial statement users with more decision-useful information about the expected creditlosses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The standard is effective for fiscalyears and interim periods within those fiscal years beginning after December 15, 2019. Early adoption is permitted for fiscal years and interim periods withinthose fiscal years beginning after December 15, 2018. The Company does notF-16believe the adoption of this standard will have a significant impact on its financial statements, given the high credit quality of the obligors to its available-for-sale debt securities and its limited history of bad debt expense relating to trade accounts receivable. Note 3. InventoryInventory, net of allowance, consisted of the following as of the date indicated: December 31, 2017 2016 Raw materials $984,328 $1,222,437 Work in process 376 1,762 Finished goods 257,959 557,161 Total gross inventory 1,242,663 1,781,360 Less inventory allowance (62,142) (270,307) $1,180,521 $1,511,053 Note 4. Fair ValueFinancial assets and liabilities measured at fair value are classified in their entirety in the fair value hierarchy, based on the lowest level input significant tothe fair value measurement. The following table classifies the Company’s financial assets and liabilities measured at fair value on a recurring basis atDecember 31, 2017 and 2016, respectively, in the fair value hierarchy: Balance at December 31, 2017 Level 1 Level 2 Level 3 Total Asset included in: Cash and cash equivalents Money market securities $8,521,054 $— $— $8,521,054 Total $8,521,054 $— $— $8,521,054 Balance at December 31, 2016 Level 1 Level 2 Level 3 Total Asset included in: Cash and cash equivalents Money market securities $6,443,102 $— $— $6,443,102 Investments available-for-sale at fair value U.S. government obligations $1,300,663 $— $— $1,300,663 Corporate debt securities $— $3,004,238 $— $3,004,238 Total $7,743,765 $3,004,238 $— $10,748,003 There were no other financial instruments subject to fair value measurement on a recurring basis. Transfers to and from Levels 1, 2 and 3 are recognized at theend of the reporting period. There were no transfers between levels for the years ended December 31, 2017 and 2016.Level 1 instruments include investments in money market funds, U.S. Treasuries and U.S. government agency obligations. These instruments are valuedusing quoted market prices for identical unrestricted instruments in active markets. The Company defines active markets for debt instruments based on boththe average daily trading volume and the number of days with trading activity. Level 2 instruments include corporate debt securities. Valuations of Level 2instruments can be verified to quoted prices, recent trading activity for identical or similar instruments, broker or dealer quotations or alternative pricingsources with reasonable levels of price transparency. Consideration is given to the nature of the quotations (e.g. indicative or firm) and the relationship ofrecent market activity to the prices provided from alternative pricing sources.F-17Fair values of these assets and liabilities are based on prices provided by independent market participants that are based on observable inputs using market-based valuation techniques.

Debt Obligations.Growth Term LoanIn August 2014, the Company entered into a Loan and Security Agreement (the “Growth Term Loan”) with a syndicate of two lending institutions, OxfordFinance LLC and Silicon Valley Bank, which was amended in August 2015 and June 2016. The first tranche of the Growth Term Loan (“Growth Term LoanA”) of $11.0 million was funded in August 2014. The second tranche of $5.0 million (“Growth Term Loan B”) was funded in March 2016. With the August2015 amendment, the interest-only payment period for the Growth Term Loan was extended until April 1, 2016. Following the interest-only payment period,the Company became obligated to make equal monthly payments of principal and interest amortized over the remaining term of the loan for all funds drawnunder the Growth Term Loan. Growth Term Loan A and B bear interest at the fixed rates of 8.5% and 8.75% per annum, respectively, and mature in September2018. The amended agreement includes a prepayment fee of 1% of the principal amount repaid if the Growth Term Loan is repaid after the secondanniversary of the August 2015 amendment and prior to maturity.The Growth Term Loan requires the Company to maintain compliance with specific operating and reporting covenants and does not require financialcovenants. The Growth Term Loan is secured by a lien covering substantially all of the Company’s assets, excluding patents, trademarks and otherintellectual property rights (except for rights to payment related to the sale, licensing or disposition of such intellectual property rights) and certain otherspecified property. If the Company were to default under the Growth Term Loan, its lenders could foreclose on its assets, including substantially all of itscash, which is held in accounts with its lenders.The remaining principal repayments due under the Growth Term Loan as of December 31, 2017, are as follows: 2018 Growth Term Loan payments $5,163,822 Less discount and deferred financing costs (64,807)Plus final fee premium 694,584 Total Growth Term Loan, net $5,793,599 Following the August 2015 amendment, the final payment percentage on the Growth Term Loan was increased to 4.75%, resulting in a final fee premiumrelating to Growth Term Loan A of $522,500 and a final fee premium relating to the Growth Term Loan B of $237,500. Each final fee premium is beingamortized to interest expense, using the effective interest method, over the term of the related Growth Term Loan tranche. Total Growth Term Loan final feepremium amortization for the year ended December 31, 2017 was $205,890, compared to $273,786 for the year ended December 31, 2016.The Company received Growth Term Loan A proceeds net of a $0.3 million original issuance discount. In addition, in connection with Growth Term Loan A,the Company issued preferred stock warrants to the lenders which were automatically converted to common stock warrants exercisable for up to 23,396 sharesof common stock at an exercise price of $23.51 per share upon completion of the Company’s initial public offering (“IPO”) in May 2015. The warrants expireon August 22, 2024. The original issuance discount and warrant discount are being amortized, using the effective interest method, over the term of GrowthTerm Loan A.In connection with the funding of Growth Term Loan B, in March 2016, the Company issued Oxford Finance LLC a common stock warrant exercisable for45,307 shares of common stock at an exercise price of $2.759 per share, and the warrant issued to Silicon Valley Bank automatically became exercisable foran additional 5,317 shares of common stock at an exercise price of $23.51 per share in accordance with the terms of the Growth Term Loan. The fair value ofthis discount of $122,460 was calculated using the Black-Scholes option pricing model at March 31, 2016. The warrant discount is being amortized, usingthe effective interest method, over the term of Growth Term Loan B.Total amortization expense for the Growth Term Loan A and B warrant discounts and the Growth Term Loan A original issuance discount was $179,931 and$249,868 for the years ended December 31, 2017 and 2016, respectively, and is included in interest expense in the accompanying statements of operations.The Company has also recorded approximately $6,269 and $24,909 of deferred financing costs net of the related debt in the accompanying balance sheets asof December 31, 2017 and 2016, respectively, in accordance with ASU 2015-03, which was adopted on January 1, 2016. Growth Term Loan deferredfinancing cost amortization expense was $18,640 and $27,468 for the years ended December 31, 2017 and 2016, respectively, and is included in interestexpense in the accompanying statements of operations.The June 2016 Growth Term Loan amendment modified the definitions of permitted indebtedness and permitted liens to provide for an increased maximumamount of permitted indebtedness, authorize a new category of permitted indebtedness and authorize a new category of permitted liens.F-19Other Debt Obligations to Related PartiesRefer to Note 15 below for discussion of debt obligations to related parties. Note 9. Other AgreementsNuvoGen ObligationThe Company entered into an asset purchase agreement in 2001, as amended, with NuvoGen Research, LLC (“NuvoGen”) to acquire certain intellectualproperty from NuvoGen. The Company accounted for the transaction as an asset acquisition. However, as the intellectual property was determined to nothave an alternative future use, the upfront consideration was expensed. In exchange for the intellectual property, the Company initially paid NuvoGen 5,587shares of the Company’s common stock, fixed payments of $740,000 over the first two years of the agreement and agreed to pay NuvoGen the greater of$400,000 annually, in quarterly installments, or 6% of its yearly revenue, which percentage payment would be reduced by any fixed payment installmentsmade during the applicable period, until the total aggregate cash compensation paid to NuvoGen under the agreement equaled $15,000,000. Certain terms ofthe agreement were amended in November 2003, September 2004, November 2012 and February 2014. Pursuant to the latest amendment to the agreement,the Company paid yearly fixed fees, in quarterly installments, to NuvoGen of $800,000 and $543,750 for the years ended December 31, 2017 and 2016,respectively. Although the amendment allowed for the deferral of any revenue-based payments through December 31, 2017, no revenue-based payments havebeen deferred, and additional revenue-based payments of $85,574 and $0 were payable as of December 31, 2017 and 2016, respectively, for the amount bywhich 6% of revenue exceeded the applicable fixed fee. As of January 1, 2018, the Company, again, is obligated to pay the greater of $400,000 or 6% ofannual revenues until the obligation is paid in full. As of that date and continuing until the remaining obligation has been paid in full, interest on theremaining unpaid obligation will accrue and compound annually at a rate of 2.5% per year. Accrued interest on this unpaid obligation is payable on the datethat the remaining obligation is paid in full. The obligation was, but is no longer, secured by certain patents and trademarks.The remaining minimum principal payments due to NuvoGen on the remaining unpaid obligation at December 31, 2017 are as follows, although actualpayments could be significantly more than provided in the table in 2018 and beyond to the extent that 6% of revenue exceeds $400,000: 2018 $400,000 2019 400,000 2020 400,000 2021 400,000 2022 400,000 2023 and beyond 5,898,743 Total NuvoGen obligation payments 7,898,743 Less discount 118,612 Total NuvoGen obligation, net $8,017,355 The Company has recorded the obligation at the estimated present value of the future payments using a discount rate of 2.5%, the Company’s estimate of itseffective borrowing rate for similar obligations. Unamortized debt discount was $(118,612) and $76,636 at December 31, 2017 and 2016, respectively.Discount accreted during the years ended December 31, 2017 and 2016 was $195,248, and $206,985, respectively.Illumina, Inc. AgreementIn June 2017, the Company entered into an Amended and Restated Development and Component Supply Agreement with Illumina, Inc., (“Illumina”),effective May 31, 2017 (the “Restated Agreement”), which amended and restated the parties’ IVD Test Development and Component Supply Agreemententered into in October 2014 (the “Original Agreement”). The Restated Agreement provides for the development and worldwide commercialization by theCompany of nuclease-protection-based RNA or DNA profiling tests (“IVD test kits”) for use with Illumina’s MiSeqDx sequencer in the field of diagnosticoncology testing in humans (the “Field”).Under the Restated Agreement, the parties have agreed to continue activities under the first development plan which was entered into pursuant to theOriginal Agreement, and the Company may, at its discretion, submit additional development plans for IVD test kits in the Field to Illumina for its approval,not to be unreasonably withheld.Under each development plan, Illumina will provide specified regulatory support and rights, and develop and deliver to the Company an executable versionof custom software, which, when deployed on Illumina’s MiSeqDx sequencer, would enable sequencing by the end-user of the subject IVD test kit probelibrary. Illumina retains ownership of the custom software, subject to the Company’s right toF-20use the custom software in connection with the commercialization of IVD test kits. The Company is required to pay Illumina up to $0.6 million in theaggregate upon achievement of specified regulatory milestones relating to the IVD test kits, though none of these regulatory milestones have been reachedthrough December 31, 2017. In addition, the Company has agreed to pay Illumina a single digit percentage royalty on net sales of any IVD test kits that theCompany commercializes pursuant to the Restated Agreement.The Company submitted two additional development plans for IVD test kits to Illumina in the second quarter and fourth quarters of 2017. Following receiptof the custom software module for the first of these test kits, the Company paid Illumina $50,000. No payments were made to Illumina during the year endedDecember 31, 2016. Costs incurred for development plans under the Restated Agreement have been expensed as incurred to research and developmentexpense in the accompanying statements of operations.Absent earlier termination, the Restated Agreement will expire in May 2027; however, Illumina is no longer obligated to notify the Company of changes inits products that may affect the Company’s IVD test kits after May 31, 2023. The Company may terminate the Restated Agreement at any time upon 90 days’written notice and may terminate any development plan under the Restated Agreement upon 30 days’ prior written notice. Illumina may terminate theRestated Agreement upon 30 days’ prior written notice if the Company undergoes certain changes of control, subject to a transition period of up to 12months for then-ongoing development plans. Either party may terminate the Restated Agreement upon the other party’s material breach of the RestatedAgreement that remains uncured for 30 days, or upon the other party’s bankruptcy.Invetech PTY Ltd. AgreementIn September 2015, the Company entered into a development and professional services agreement with Invetech PTY Ltd. (“Invetech”), for the conduct ofresearch and development of a next generation automated sample library preparation instrument. This instrument is intended for laboratories with lowvolume sample throughput. This instrument design and development program is being referred to as Project JANUS.The agreement requires the execution of a development plan for each stage of the project. Upon full execution and delivery of each development plan, theCompany will pay Invetech development fee installments for that development plan. Stage 0 was completed during the second half of 2015. In July 2016, theCompany entered into an amendment with Invetech, extending and concluding Stage 1.1 through the end of July 2016 and further suspending Invetech’sproject development activities until the Company makes the decision to resume further external development efforts consistent with its developmentpriorities. The Invetech agreement remains in effect through completion of all tasks and the Company’s acceptance of all deliverables under eachdevelopment plan unless terminated earlier as provided for in the agreement.Research and development expense included in the statements of operations relating to Invetech development fee installments was $0 and $2.3 million forthe years ended December 31, 2017 and 2016, respectively.Bristol-Myers Squibb Company AgreementIn May 2016, the Company entered into a Collaboration Agreement with Bristol-Myers Squibb Company (“BMS”) for the development of custom RUOassays for BMS based on the Company’s HTG EdgeSeq technology. Following development of each assay, at BMS’s request, the Company may also performsample processing services using such custom RUO assay(s) and/or supply the custom RUO assay(s) to BMS or its third-party subcontractors. Additionalcustom RUO assay development related to immuno-oncology research may be undertaken pursuant to the agreement in accordance with a mutuallyacceptable work plan, which is incorporated by written amendment.BMS paid an initial non-refundable, non-creditable program set-up fee, and has agreed to pay an annual non-refundable, non-creditable project managementfee in quarterly installments, as well as a fee for each assay developed. Each such fee was or is in the low six-figure range. At BMS’s request, custom RUOassay kits will be supplied and sample processing services will be performed by the Company.The agreement will expire on May 11, 2019 or, if a project is then ongoing, the date of delivery of the final report for such project. Either party may terminatethe agreement upon the other party’s material breach or default in the performance of a material obligation under the agreement or if certain warranties orrepresentations are untrue in any material respect (either a “Default”) and such Default remains uncured for 60 days or such longer period if the Defaultcannot be cured within 60 days. BMS may terminate a project upon 90 days’ prior written notice to the Company.The agreement is a multiple-element arrangement under ASC 605-25. Custom RUO assay development services, custom kit sales and sample processingservices were each designated as an option to purchase additional products or services as described under ASC 605-25, and, as such, will not be considered inthe initial allocation of contract consideration based on relative selling prices.F-21Each custom RUO assay development service has three phases and each phase comprises multiple deliverables. Completion of all three phases is required forBMS to derive benefit from the respective deliverables; therefore, the three phases of an assay’s development will be combined as one unit of accounting forrevenue recognition purposes.Under ASC 605-25, fixed or determinable contract consideration is allocated to the deliverables with stand-alone value, and revenue is recognized for eachsuch deliverable according to the method appropriate for each deliverable. All of the fixed or determinable contract consideration will be allocated to onedeliverable, which is the research and development services culminating in the delivery of two custom RUO assays.The quarterly project management fees and the initial set-up fee are being recognized as the custom RUO assay development services are performed on aproportional performance basis. Each assay development fee is also being recognized on a proportional performance basis as these services are provided.Because the assay development fees are contingent upon completion of each individual phase of the design project and the decision by BMS to proceed tothe next phase, the amount recognized will be limited to that which BMS is contractually obligated to pay upon completion of that phase. For the years ended December 31, 2017 and 2016, $125,000 and $189,422, respectively, was recognized under the agreement as product and product-relatedservices revenue in the statements of operations. Deferred revenue relating to this agreement of $160,106 was included in the balance sheets as of bothDecember 31, 2017 and 2016. See Note 16 for discussion of the amendment of this agreement in the first quarter of 2018.Merck KGaA AgreementIn October 2016, the Company entered a Master CDx Agreement with Merck KGaA, Darmstadt, Germany, (“Merck KGaA”) to serve as the basis for one ormore project agreements to develop, seek regulatory approval for, and commercialize companion diagnostics for Merck KGaA drug candidates andcorresponding therapeutics. Concurrently, the parties entered into a first project agreement under the agreement concerning the Company’s sequencing-basedDLBCL cell of origin assay (“DLBCL Assay”) and Merck KGaA’s investigational drug, M7583 (the “Project”).The Project has three stages aligned with timelines and outcomes of M7583 development. The timing of the Company’s activities and payments may beaffected by M7583 development activities and timing which are controlled by Merck KGaA. During stages 1 and 2, the Company will perform specifiedDLBCL Assay development activities. In stage 3, the Company will obtain applicable regulatory approvals on the DLBCL Assay and make it commerciallyavailable in the United States and certain other jurisdictions.Stages 2 and 3 each have an up-front payment and all stages of the Project have milestone-based payments. The Company is eligible to receive up to a totalof approximately $1,850,000 over the next five years and $9,900,000 over a period of approximately nine years in fixed or determinable contractconsideration comprising up-front and milestone payments. In addition, during stages 1 and 2 of the Project, the Company may sell DLBCL Assay kits and/orperform sample processing services upon request of, and as instructed by, Merck KGaA. The up-front and milestone-based payments could be delayed due tothe risks of completing development activities and obtaining regulatory approvals within projected timeframes.Merck KGaA may terminate the Project by providing 90 days’ prior written notice to the Company, at which point Merck KGaA will reimburse HTG for costsincurred during the termination period, of an amount not to exceed non-cancellable, non-reimbursable expenses, and HTG will reimburse Merck KGaA forany costs that have been prepaid without being incurred prior to termination. Further, either party may also terminate the agreement upon the other party’smaterial breach that remains uncured for 45 days or upon the other party’s bankruptcy.The agreement is a multiple-element arrangement under ASC 605-25 and a collaborative arrangement under ASC 808. Kit sales and sample processingservices have been designated as an option to purchase additional products or services as described under ASC 605-25, and, as such, will not be considered inthe initial allocation of contract consideration based on relative selling prices. The remaining deliverables, including licenses to HTG patents and researchand development services, do not have standalone value and are combined into one unit of accounting.Under ASC 605-25, fixed or determinable contract consideration is allocated to the deliverables with stand-alone value, and revenue is recognized for eachsuch deliverable according to the method appropriate for each deliverable. All of the fixed or determinable contract consideration will be allocated to onedeliverable, which is the research and development services.Non-refundable up‑front payments will be received at the initiation of stages 2 and 3. These payments will be recognized as revenue over the period that theresearch services are expected to occur. All other payments are contingent upon completion of milestones. Costs incurred to date compared to total expectedcosts are used to determine proportional performance, as this is considered to be representative of the delivery of outputs under the Project. Revenuerecognized at any point in time is limited to cash received and amounts contractually due.F-22The Company earned the first milestone-based payment under the Master Agreement in the second quarter of 2017, resulting in recognition of collaborativedevelopment service revenue of $25,000 and $0 using the proportional performance method of revenue recognition for the years ended December 31, 2017and 2016, respectively. No additional milestones have been reached as of December 31, 2017.Other Agreements with Related PartiesRefer to Note 15 below for discussion of agreements with related parties. Note 10.

On January 1,2018, an additional 557,190 shares were registered for issuance under the 2014 Plan pursuant to an evergreen provision contained in the 2014 Plan.The Company’s Board of Directors determines the grant date for all awards granted under the 2014 Plan. The option exercise price of stock options granted isgenerally equal to the closing price of the Company’s common stock on the date of grant. All stock options granted have a ten-year term. The vesting periodof stock options and RSUs is established by the Board of Directors but typically ranges between one and four years.The following table summarizes stock option activity during the two-year period ended December 31, 2017: Number ofShares Weighted-AverageExercisePricePer Share Weighted-AverageRemainingContractualLife (Years) AggregateIntrinsic Value Balance at January 1, 2016 736,645 $4.18 7.5 $947,794 Granted 563,400 2.46 Exercised (11,093) 2.15 $2,126 Forfeited (70,754) 4.6 Expired/Cancelled (56,493) 3.97 Balance at December 31, 2016 1,161,705 $3.35 7.7 $36,887 Granted 494,500 2.09 Exercised (41,815) 2.68 $152,130 Forfeited (81,676) 2.64 Expired/Cancelled (14,943) 6.15 Balance at December 31, 2017 1,517,771 $2.97 7.5 $67,242 Vested and expected to vest at December 31, 2017 1,517,771 $2.97 7.5 $67,242 Exercisable at December 31, 2016 593,670 $3.46 6.4 $28,822 Exercisable at December 31, 2017 851,996 $3.31 6.5 $248 F-25The weighted-average fair value of stock options granted was $1.14 and $1.59 for the years ended December 31, 2017 and 2016, respectively. As ofDecember 31, 2017, total unrecognized compensation cost related to stock option awards was approximately $723,590, which is expected to be recognizedover approximately 1.76 years.In April 2016, in connection with the severance of an employee, the Company accelerated the vesting of 8,957 unvested stock options, as well as the periodfollowing termination whereby all of the employee’s vested stock options, including those accelerated as part of the severance agreement, could be exercisedfor a two-year period from the termination date. As a result of this modification, the Company recorded incremental stock-based compensation expense ofapproximately $13,500 for the year ended December 31, 2016.The fair value of each stock option granted has been determined using the Black-Scholes option pricing model. The material factors incorporated in theBlack-Scholes model in estimating the fair value of the stock options granted for the periods presented were as follows: 2017 2016 Fair value of common stock $1.71 - 3.46 $1.98 - 2.88 Risk-free interest rate 1.75% - 2.20% 1.13% - 2.08% Expected volatility 58.5% - 62.6% 59.9% - 93.7% Expected term 5.1 to 6.3 years 4.8 to 6.2 years Expected dividend yield 0% 0% •Expected stock price volatility. The expected volatility assumption is derived from the volatility of the Company’s common stock in recentperiods, as well as that of publicly traded industry competitors, over a period approximately equal to the expected term. •Risk-free interest rate. The risk-free interest rate assumption is based on observed interest rates on the date of grant with maturitiesapproximately equal to the expected term. •Expected term. The expected term represents the period that the stock-based awards are expected to be outstanding. The Company’s historicalshare option exercise experience does not provide a reasonable basis upon which to estimate an expected term because of a lack of sufficientdata. Therefore, the Company estimates the expected term by using the simplified method provided by the SEC. The simplified methodcalculates the expected term as the average of the time-to-vesting and the contractual life of the stock options. •Expected dividend yield. The expected dividend is assumed to be zero as the Company has never paid dividends and does not anticipatepaying any dividends on its common stock.In addition to the assumptions used in the Black-Scholes option-pricing model outlined above, the Company elected to change its policy surroundingforfeitures of equity awards with the adoption of the guidance in ASU No. 2016-09 on January 1, 2017. As of that date, the Company no longer estimates aforfeiture rate to calculate stock-based compensation. The Company implemented this portion of the guidance using a modified retrospective approach. Thecumulative adjustment was not material to additional paid-in capital. The Company will continue to use judgment in evaluating the expected volatility andexpected terms utilized for the Company’s stock-based compensation calculations on a prospective basis.The following table summarizes RSU award activity during the two-year period ended December 31, 2017: Number ofShares Weighted-AverageGrant DateFair ValuePer Share Balance at January 1, 2016 27,500 $5.45 Granted 389,761 2.43 Vested (36,762) 2.90 Forfeited (25,000) 2.46 Balance at December31, 2016 355,499 $2.41 Granted 10,000 1.75 Vested (336,333) 2.47 Forfeited (2,500) 2.46 Balance at December 31, 2017 26,666 $2.78 Vested and expected to vest at December 31, 2017 26,666 $2.78 F-26The weighted-average fair value of RSUs granted was $1.75 and $2.43 for the years ended December 31, 2017 and 2016, respectively. As of December 31,2017, total unrecognized compensation cost related to RSU awards was approximately $53,368, which is expected to be recognized over approximately 1.78years.2014 Employee Stock Purchase PlanIn April 2015, the Company’s stockholders approved the 2014 Employee Stock Purchase Plan (“ESPP”), which became effective in May 2015. Initially, theESPP authorized the issuance of up to 110,820 shares of common stock pursuant to purchase rights granted to the Company’s employees or to employees ofany of the Company’s designated affiliates. The number of shares of common stock reserved for issuance automatically increases on January 1 of eachcalendar year, from January 1, 2016 to January 1, 2024 by the least of (i) 1% of the total number of shares of the Company’s common stock outstanding onDecember 31 of the preceding calendar year, (ii) 195,000 shares, or (iii) a number determined by the Company’s board of directors that is less than (i) and (ii).The ESPP enables participants to contribute up to 15% of such participant’s eligible compensation during a defined period (not to exceed 27 months) topurchase common stock of the Company. The purchase price of common stock under the ESPP is the lesser of: (i) 85% of the fair market value of a share ofthe Company’s common stock on the first day of an offering or (ii) 85% of the fair market value of the Company’s common stock at the applicable purchasedate.During the year ended December 31, 2017, employees purchased 39,972 shares at $1.79 per share and 39,969 shares at $1.61 per share at the end of each ofthe ESPP’s six-month purchase periods. During the year ended December 31, 2016, employees purchased 39,984 shares at $1.83 per share and 39,978 sharesat $2.54 per share at the end of each of the ESPP’s six-month purchase periods. As of December 31, 2017, approximately 98,744 shares of the Company’scommon stock were reserved for future issuance under the ESPP. On January 1, 2018, an additional 139,297 shares were registered for issuance pursuant to anevergreen provision contained in the ESPP.The Company recognizes ESPP expense based on the fair value of the ESPP stock purchase rights, estimated for each six-month purchase period using theBlack-Scholes option pricing model. The model requires the Company to make subjective assumptions, including expected stock price volatility, risk freerate of return and estimated life. The fair value of equity-based awards is amortized straight-line over the vesting period of the award.The material factors incorporated in the Black-Scholes model in estimating the fair value of the ESPP awards for the periods presented were as follows: 2017 2016 Fair value of common stock $2.11 - 3.17 $3.03 - 4.09 Risk-free interest rate 0.61% - 1.12% 0.41% - 0.48% Expected volatility 68.0% - 70.0% 70.0% Expected term 0.5 years 0.5 years Expected dividend yield -% -% •Fair value of common stock. Estimated as the price of the Company’s common stock on the first day of each offering period. •Expected stock price volatility. The expected volatility assumption is derived from the average volatility of the Company’s common stock inrecent periods, as well as that of publicly traded industry competitors, over a period approximately equal to the expected term. •Risk-free interest rate. The risk-free interest rate assumption is based on observed interest rates on the first day of the purchase period withmaturities approximately equal to the expected term. •Expected term. The expected term represents the length of a purchase period under the ESPP. •Expected dividend yield. The expected dividend is assumed to be zero as the Company has never paid dividends and does not anticipatepaying any dividends on its common stock.Stock Purchase PlanIn December 2015, the Board of Directors adopted a Stock Purchase Plan (the “Purchase Plan”) which allows directors, any individual deemed by the Boardof Directors to be an officer for purposes of Section 16 of the Exchange Act, and anyone designated by the Board of Directors as eligible to participate in thePurchase Plan to purchase shares of the Company’s common stock from the Company at fair market value. The aggregate number of shares of common stockthat may be issued under the Purchase Plan shall not exceed 250,000 shares of common stock, and a maximum of 7,500 shares of common stock may bepurchased by any one participantF-27on any one purchase date. The Board of Directors or an authorized committee must review and approve each individual request to purchase common stockunder the Purchase Plan. Cash received from the sale of common stock by the Company to eligible participants for the year ended December 31, 2017 was$130,649 which resulted in the sale of 61,141 shares of the Company’s common stock at fair market value. No common stock was sold by the Companyunder the Purchase Plan for the year ended December 31, 2016. Note 13. Commitments and ContingenciesLegal MattersThe Company’s industry is characterized by frequent claims and litigation, including claims regarding intellectual property and product liability. As a result,the Company may be subject to various legal proceedings from time to time. The results of any current or future litigation cannot be predicted with certainty,and regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, andother factors. Any current litigation is considered immaterial and counter claims have been assessed as remote.Employment AgreementsThe Company has entered into employment agreements or other arrangements with certain named executive officers, which provides salary continuationpayments, bonuses and, in certain instances, the acceleration of the vesting of certain equity awards to individuals in the event that the individual isterminated other than for cause, as defined in the applicable agreement.Indemnification AgreementsIn the course of operating its business, the Company has entered into, and continues to enter into, separate indemnification agreements with the Company’sdirectors and executive officers, in addition to the indemnification provided for in the Company’s amended and restated bylaws. These agreements mayrequire the Company to indemnify its directors and executive officers for certain expenses incurred in any action or proceeding arising out of their services asone of the Company’s directors or executive officers.LeasesThe Company leases office and laboratory space under two non-cancelable operating leases in Tucson, Arizona. The Company amended its facilities leases inAugust 2015 to extend the terms for approximately five years and to receive lessor approval for and establish lessee oversight of leasehold improvements bythe Company and the lessor, respectively, which improvements expanded and improved the Company’s existing research, development, operations andadministrative office facilities. The lease amendments included an increase of $804,000 in total monthly rent over the remaining term of the leases. Thelandlord constructed certain of the leasehold improvements as an incentive to extend the leases. The total cost of the improvements constructed by thelandlord of $710,000 was capitalized when the construction was completed in February 2016, and is being depreciated over the remaining term of the leaseagreement. The incentive of $710,000 has been recognized as deferred rent within other current liabilities and other liabilities on the balance sheets, and isbeing accreted at $11,833 per month over the lease term as a reduction of rent expense.The Company’s annual minimum facility lease payments before common area maintenance charges as of December 31, 2017 are as follows: 2018 $512,533 2019 514,977 2020 517,457 2021 43,139 $1,588,106 Rent expense, including common area maintenance costs for the Company’s facilities leases was $570,979, including $142,000 of depreciation forcapitalized leasehold improvements for the year ended December 31, 2017. Rent expense, including common area maintenance costs for the Company’sfacility leases was $561,293, including $130,167 of depreciation for capitalized leasehold improvements for the year ended December 31, 2016.As of December 31, 2017, the Company also has capital lease commitments consisting of approximately $83,000 under leases for computer equipmentvarying in length from 36-48 months that have not been included in the minimum lease payments schedule above.F-28Product WarrantyThe following is a summary of the Company’s general product warranty liability, which is included in accrued liabilities in the accompanying balance sheetsfor the years ended December 31, 2017 and 2016: Years Ended December 31, 2017 2016 Beginning balance $50,426 $20,213 Cost of warranty claims (9,814) (71,404)Increase (decrease) in warranty reserve (3,456) 101,617 Ending balance $37,156 $50,426 Defined Contribution PlanIn January 2003, the Company established a defined contribution plan (“401(k) Plan”) under section 401(k) of the IRC. All employees who are over the ageof 21 and who are expected to work at least 1,000 hours in a calendar year are eligible for participation in the 401(k) Plan upon commencement ofemployment with the Company. The Company may make discretionary contributions to the 401(k) Plan, but has not done so during the years endedDecember 31, 2017 and 2016. Note 14. Income TaxesThe Company provides for income taxes based upon management’s estimate of taxable income or loss for each respective period. The Company recognizesan asset or liability for the deferred tax consequences of temporary differences between the tax bases of assets and liabilities and their reported amounts in thefinancial statements. These temporary differences would result in deductible or taxable amounts in future years, when the reported amounts of the assets arerecovered or liabilities are settled, respectively.In each period since inception, the Company has recorded a valuation allowance for the full amount of its net deferred tax assets, as the realization of the netdeferred tax assets is uncertain. As a result, the Company has not recorded any federal or state income tax benefit in the statements of operations; however,state income tax expense has been recorded for state minimum taxes.The Company periodically reviews its filing positions for all open tax years in all U.S. federal, state and international jurisdictions where the Company is ormight be required to file tax returns or other required reports.The Company applies a two-step approach to recognizing and measuring uncertain tax positions. The Company evaluates the tax position for recognition bydetermining if the weight of available evidence indicates that it is “more likely than not” that the position will be sustained on audit, including resolution ofrelated appeals or litigation process, if any. The term “more likely than not” means a likelihood of more than 50 percent. If the tax position is not more likelythan not to be sustained in a court of last resort, the Company may not recognize any of the potential tax benefit associated with the position. The Companyrecognizes a benefit for a tax position that meets the more likely than not criterion at the largest amount of tax benefit that is greater than 50 percent likely ofbeing realized upon its effective resolution. Unrecognized tax benefits involve management’s judgment regarding the likelihood of the benefit beingsustained. The final resolution of uncertain tax positions could result in adjustments to recorded amounts and may affect the Company’s results of operations,financial position and cash flows. The Company has not identified any uncertain tax positions at December 31, 2017 or 2016.The Company’s policy is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company had no accrual for interestor penalties at December 31, 2017 or 2016, and has not recognized interest or penalties during the years ended December 31, 2017 and 2016, since there areno material unrecognized tax benefits. Management of the Company does not expect a material change to the amount of unrecognized tax benefits to occurwithin the next 12 months.F-29The components of income tax expense are as follows: Years Ended December 31, 2017 2016 Current: Federal $— $— State 2,921 10,118 Total current income tax expense $2,921 $10,118 Deferred: Federal $— $— State — — Total deferred income tax expense $— $— Total income tax expense $2,921 $10,118 The Company’s actual income tax expense for the years ended December 31, 2017 and 2016 differ from the expected amount computed by applying thestatutory federal income tax rate of 34% to loss before income taxes as follows: Years Ended December 31, 2017 2016 Computed tax (benefit) at 34% $(6,445,413) $(8,850,007)State taxes, net of federal benefit (532,952) (462,609)Stock-based compensation 231,396 210,367 Expiring state NOL carryforwards — 94,962 Return to provision (15,375) 248,263 Other 20,292 25,718 Research and development tax credit - state (576,525) (453,071)Research and development tax credit - federal (440,058) (341,785)Federal rate change on deferred items as of enactment date 16,232,211 — Change in valuation reserve (8,470,655) 9,538,280 $2,921 $10,118Deferred tax assets and liabilities comprise the following: Years Ended December 31, 2017 2016 Deferred tax assets: Net operating loss carryforwards $29,475,597 $37,114,445 Research and development credits 3,114,091 2,132,050 Deferred revenue 204,061 177,683 Inventory reserve 15,134 99,583 Fixed assets and intangibles 147,395 193,833 Accrued NuvoGen liability 1,952,567 3,176,449 Accrued expense 24,500 351,505 Other 74,986 233,438 35,008,331 43,478,986 Valuation allowance (35,008,331) (43,478,986)Deferred tax asset, net $— $— On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”),which makes broad and complex changes to the IRC. Certain of these changes may be applicable to the Company, including but not limited to, reducing theU.S. federal corporate tax rate from 35% to 21%, creating a new limitation on deductible interest expense, eliminating the corporate alternative minimum tax,modifying the rules related to uses and limitations of net operating loss carryforwards generated in tax years ending after December 31, 2017, and changingthe rules pertaining to the taxation of profits earned abroad. Changes in tax rates and tax laws are accounted for in the period of enactment. The Tax Actreduces the corporate tax rate to 21% effective January 1, 2018. Consequently, we have recorded a decrease related to deferred tax assets of $16,232,211,exclusive of the corresponding change in the valuation allowance, as of December 31, 2017. Due to the full valuation allowance on the deferred tax assets,there is no net adjustment to deferred tax expense or benefit due to the reduction of the corporate tax rate.F-30As of December 31, 2017, the Company has estimated federal and state net operating loss (“NOL”) carryforwards of approximately $121,980,841 and$79,222,187 for federal and state income tax purposes, respectively. The Company’s federal NOLs are scheduled to expire from 2021 through 2037. TheCompany’s state NOLs are scheduled to expire from 2027 through 2037. The Company’s federal and state tax credit carryforwards begin expiring in 2021and 2018, respectively. The Company’s federal NOL carryforwards have the following expiration dates: Year of Expiration Carryforwards Federal NOL carryforwards 2021 $211,806 2023 1,635,651 2024 1,217,290 2025 1,409,498 2026 1,175,594 2027 1,676,458 2028 3,037,785 2029 3,753,314 2030 623,235 2031 5,435,312 2032 10,913,787 2033 12,095,966 2034 14,190,409 2035 21,112,183 2036 24,302,042 2037 19,190,511 $121,980,841 For financial reporting purposes, valuation allowances of $35,008,331 and $43,478,986 at December 31, 2017 and 2016, respectively, have been establishedto offset deferred tax assets relating primarily to NOLs and research and development credits. The decrease in the valuation allowance of $8,470,655 for theyear ended December 31, 2017 was due to an increase of $7,761,556 related to additional operating losses, and a decrease of $16,232,211 related to theimpact of the Tax Act on the deferred balances as of the enactment date. The Company has established a valuation allowance against its entire tax asset. As aresult, the Company does not recognize any tax benefit until it is in a taxpaying position or there is sufficient positive evidence leading to the conclusionthat it is more likely than not to realize the tax benefit.A preliminary analysis of past and subsequent equity offerings by the Company, and other transactions that have an impact on the Company’s ownershipstructure, concluded that the Company may have experienced one or more ownership changes under Sections 382 and 383 of the IRC. Provisions of the IRCplace special limitations on the usage of NOLs and credits following an ownership change. Such limitations may limit or eliminate the potential future taxbenefit to be realized by the Company from its accumulated NOLs and research and development credits.The Company files income tax returns in the United States, Arizona, California, Texas and various other state jurisdictions, with varying statutes oflimitations. As of December 31, 2017, the earliest year subject to examination is 2014 for U.S. federal tax purposes. The earliest year subject to examination is2013 for Arizona, California and Texas, and 2009 for the remaining state jurisdictions. However, the Company’s NOL carryforwards for periods endingDecember 31, 2001 and thereafter remain subject to examination by the United States and certain states. F-31Note 15. Related Party TransactionsQML Master Assay Development, Commercialization and Manufacturing AgreementIn November 2016, the Company and QML entered into the Governing Agreement, which creates a framework for QML and the Company to combine theirtechnological and commercial strengths to offer biopharmaceutical companies a complete NGS-based solution for the development, manufacture andcommercialization of companion diagnostic assays. Under the Governing Agreement, the parties jointly seek companion diagnostic programs withbiopharmaceutical companies, QML enters into sponsor project agreements with interested biopharmaceutical companies for specified projects, and QMLand the Company enter into statements of work, which set forth the rights and obligations of QML and the Company with respect to each project.The parties’ relationship under the Governing Agreement is exclusive in the oncology field. Such exclusivity in the oncology field may be lost and becomenon-exclusive if certain performance targets are not met. Projects may be undertaken in non-oncology fields at each party’s discretion on a non-exclusivebasis.QML and the Company share net profits under each statement of work, based on whether development of particular assays under a statement of work areprimarily based on HTG or QML intellectual property. Each statement of work provides additional financial terms for the corresponding Project, which termsdepend on the respective development and/or commercialization activities of the parties.The Governing Agreement has a five-year term. However, either party may terminate the Governing Agreement upon (i) the other party’s uncured materialbreach, bankruptcy or insolvency, (ii) specified events affecting all statements of work, or (iii) a change of control by either party, except neither party willhave such change of control termination right to the extent the termination of the Governing Agreement relates to SOW One, SOW Two or SOW Three (eachdefined below). In the event a party terminates the Governing Agreement for its own change of control, a $2.0 million termination payment will be payable tothe non-terminating party.Statement of Work No. OneIn June 2017, the Company and QML entered into the first statement of work under the Governing Agreement, and amended such first statement of work inDecember 2017 (collectively, “SOW One”). SOW One addressed the initial activities of the Company and QML in support of the development and potentialcommercialization of a next generation sequencing-based companion diagnostic assay that is the subject of a sponsor project agreement between QML and abiopharmaceutical company (“Pharma One”). The parties expect certain development, manufacturing and commercialization activities for the assay to be thesubject of a second sponsor project agreement and corresponding additional statements of work under the Governing Agreement.The Company has determined that SOW One is a collaborative arrangement under ASC 808 and a multiple-element arrangement under ASC 605-25. Afterreviewing the deliverables under the arrangement, the Company concluded that all of the fixed and determinable contract consideration should be allocatedto the development services to be performed by the Company.QML pays the Company a monthly fee for development work performed by Company and its subcontractors (collectively, the “Monthly Fee”). The MonthlyFee is not contingent upon successful acceptance of project milestones by Pharma One; therefore, the Monthly Fee is recognized as the respective paymentamount becomes fixed or determinable and collectability from QML is reasonably assured. The Company and QML also will share any net profits resultingfrom performance of the development work as determined pursuant to the Governing Agreement. Such profit sharing payment(s) is deemed to be fixed ordeterminable upon completion of SOW One deliverables, acceptance of corresponding deliverables by Pharma One, and the mutual agreement by QML andthe Company on the calculation of net profit.Revenue of $2,604,892, relating to SOW One Monthly Fees, and $1,272,080, relating to SOW One profit sharing payments have been included incollaborative development services revenue in the accompanying statements of operations for the year ended December 31, 2017. Accounts receivable of$2,429,152 remains in the balance sheets as of December 31, 2017. Costs relating to development activities conducted by the Company pursuant to SOWOne of $2,129,138 have been included in research and development expense in the accompanying statements of operations for the year ended December 31,2017. No costs or revenue relating to SOW One were included in the accompanying statements of operations for the year ended December 31, 2016 as SOWOne was not effective until June 2017.SOW One will expire when all activities and deliverables have been completed by the respective responsible party and all payments from QML to theCompany have been delivered, including any required profit sharing payment, unless terminated earlier in accordance with the terms of the GoverningAgreement.F-32Contemporaneous with entry into SOW One, the Governing Agreement was amended to provide that neither the Company nor QML may terminate SOW Oneor the Governing Agreement to the extent it relates to SOW One in the event of a change of control.Statement of Work No. TwoIn October 2017, the Company and QML entered into the second statement of work under the Governing Agreement (“SOW Two”). SOW Two was madeeffective as of June 2, 2017 (“Onset Date”). SOW Two addresses development activities conducted by the Company and QML since the Onset Date and thoseexpected to be further conducted by parties in connection with a sponsor project agreement, dated June 2, 2017, between QML and BMS (the “BMS/QMLSPA”).The development work performed and expected to be performed by the Company and QML under SOW Two (“Initial Phase Work”) is expected to form thebasis of a multi-stage project leading to the potential development and commercialization of a companion diagnostic assay in support of one or more ofBMS’s therapeutic development and commercialization programs. SOW Two will expire upon completion of the Initial Phase Work and receipt by theCompany of all amounts due for such work, which the Company believes will occur in mid‑2018 barring any unexpected project delays. QML will pay theCompany mid-single digit millions of dollars for the Initial Phase Work performed by the Company under SOW Two. In addition, the Company and QMLwill share in any net profits (as determined under the Governing Agreement) generated by the Initial Phase Work on an approximately quarterly basisthroughout the SOW Two term.SOW Two also provides that, notwithstanding anything in the Governing Agreement to the contrary, neither QML nor the Company shall have the right toterminate SOW Two or the Governing Agreement to the extent it relates to SOW Two upon a change of control of either party.Concurrent with SOW Two, as a condition to BMS’s approval of SOW Two, the Company, QML and BMS entered into a Supplement Agreement, madeeffective as of the Onset Date. The Supplement Agreement establishes certain rights and obligations of the parties with regard to confidential information andother intellectual property needed to perform, and/or produced as a result of, the Initial Phase Work.

Otherwise, Project IP will be jointly owned among the Company, QML and Pharma Three.Pursuant to the terms of SOW Three, if Pharma Three terminates the sponsor project agreement with QML or the SOW Three Project due to the Company’suncured material breach of SOW Three, the Company will be required to negotiate in good faith with Pharma Three a non-exclusive, royalty-bearing licenseto certain Company intellectual property as reasonably necessary for Pharma Three to research, develop and commercialize an IVD assay meeting the samespecifications as SOW Three.Neither QML nor the Company have the right to terminate SOW Three or the Governing Agreement to the extent it relates to SOW Three upon a change ofcontrol of either party. In addition, if Pharma Three terminates the sponsor project agreement or the SOW Three Project for an uncured material breach that isdirectly caused by the Company or QML, then, for the non-breaching party, the exclusivity obligation of the Governing Agreement will terminate solely withrespect to the development for Pharma Three and/or its affiliates of an IVD assay meeting the same specifications as in SOW Three.F-34SOW Three expires upon completion of the SOW Three Project and receipt by the Company of all amounts due for such work.Bristol-Myers Squibb Agreement AmendmentIn January 2018, the Company and BMS amended the terms of the parties’ May 2016 Collaboration Agreement to increase the development fee payable byBMS to the Company for each of the two initial custom RUO assays contemplated by the agreement from a low six-figure range to a mid six-figure dollaramount, and to modify certain custom RUO assay development requirements.With the amendment of the agreement, the Company estimates that the first custom research assay development project initiated under this agreement will becompleted in the third quarter of 2018.

Controls and Procedures.Evaluation of Disclosure Controls and Procedures.We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our periodic and currentreports that we file with the SEC is recorded, processed, summarized and reported with the time periods specified in the SEC’s rules and forms, and that suchinformation is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, toallow timely decisions regarding required disclosure.In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how welldesigned and operated, can provide only reasonable and not absolute assurance of achieving the desired control objectives. In reaching a reasonable level ofassurance, management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. In addition, thedesign of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that anydesign will succeed in achieving its stated goals under all potential future conditions; over time, control may become inadequate because of changes inconditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system,misstatements due to error or fraud may occur and not be detected.As of December 31, 2017, we carried out an evaluation, under the supervision and with the participation of our management, including our ChiefExecutive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as defined inRules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended. Based on that evaluation, our Chief Executive Officer and our ChiefFinancial Officer have concluded that, as of the end of the period covered by this annual report, our disclosure controls and procedures were effective at thereasonable assurance level.Management’s Report on Internal Control over Financial Reporting.Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined inExchange Act Rules 13a-15(f). Internal control over financial reporting is a process designed under the supervision and with the participation of ourmanagement, including our Chief Executive Officer and Chief Financial Officer, to provide reasonable assurance regarding the reliability of financialreporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United Statesof America. The effectiveness of any system of internal control over financial reporting, including ours, is subject to inherent limitations, including theexercise of judgment in designing, implementing, operating and evaluating the controls and procedures, and the inability to eliminate misconductcompletely. Accordingly, any system of internal control over financial reporting, including ours, no matter how well designed and operated, can only providereasonable, not absolute assurances. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls maybecome inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Therefore, even thosesystems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.We conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control –Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on our evaluation of theframework in Internal Control – Integrated Framework, our management concluded that our internal control over financial reporting was effective as ofDecember 31, 2017.Changes in Internal Control Over Financial ReportingAn evaluation was performed under the supervision and with the participation of our management, including our Chief Executive Officer and ChiefFinancial Officer, of any change in our internal control over financial reporting that occurred during our last fiscal quarter and that has materially affected, oris reasonably likely to materially affect, our internal control over financial reporting. That evaluation did not identify any change in our internal control overfinancial reporting that occurred during our latest fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal controlover financial reporting.Item 9B.

Theprimary responsibilities of our board of directors are to provide oversight, strategic guidance, counseling and direction to our management. Our board ofdirectors meets on a regular basis and additionally as required.Our board of directors has determined that all of our directors other than Mr. Johnson are independent directors, as defined by Rule 5605(a)(2) of theNasdaq Listing Rules. The Nasdaq independence definition includes a series of objective tests, including that the director is not, and has not been for at leastthree years, one of our employees and that neither the director nor any of his family members has engaged in various types of business dealings with us. Inaddition, as required by Nasdaq rules, our board of directors has made a subjective determination as to each independent director that no relationships exist,which, in the opinion of our board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Inmaking these determinations, our board of directors reviewed and discussed information provided by the directors and us with regard to each director’sbusiness and personal activities and relationships as they may relate to us and our management. There are no family relationships among any of our directorsor executive officers.In accordance with the terms of our amended and restated certificate of incorporation, our board of directors is divided into three classes, as follows: •Class I, which consists of Mr. McCracken and Mr. LaFrance, whose terms will expire at our annual meeting of stockholders to be held in 2019; •Class II, which consists of Mr. George and Mr. Hardison, whose terms will expire at our annual meeting of stockholders to be held in 2020; and •Class III, which consists of Mr. Johnson, Mr. Shuster and Dr. Hanham, whose terms will expire at our annual meeting of stockholders to be heldin 2018.At each annual meeting of stockholders, the successors to directors whose terms then expire will serve until the third annual meeting following theirelection and until their successors are duly elected and qualified. The authorized number of directors may be changed only by resolution of our board ofdirectors. Any additional directorships resulting from an increase in the number of directors will be distributed between the three classes so that, as nearly aspossible, each class will consist of one-third of the directors. This classification of the board of directors may have the effect of delaying or preventingchanges in our control or management. Our directors may be removed for cause by the affirmative vote of the holders of at least 66 2/3% of our voting stock.Board Leadership StructureOur board of directors is currently chaired by Dr. Hanham. As a general policy, our board of directors believes that separation of the positions of chairand Chief Executive Officer reinforces the independence of the board of directors from management, creates an environment that encourages objectiveoversight of management’s performance and enhances the effectiveness of the board of directors as a whole. As such, Mr. Johnson serves as the President andChief Executive Officer while Dr. Hanham serves as the chair of our board of directors but is not an officer. We expect the positions of chair of the board ofdirectors and Chief Executive Officer to continue to be held by two individuals in the future.74 Role of the Board in Risk OversightOne of the key functions of our board of directors is informed oversight of our risk management process. The board of directors does not have astanding risk management committee, but rather administers this oversight function directly through the board of directors as a whole, as well as throughvarious standing committees of our board of directors that address risks inherent in their respective areas of oversight. The risk oversight process includesreceiving regular reports from board committees and members of senior management to enable our board to understand our risk identification, riskmanagement and risk mitigation strategies with respect to areas of potential material risk, including operations, finance, legal, regulatory, strategic andreputational risk. In particular, our board of directors is responsible for monitoring and assessing strategic risk exposure and our audit committee has theresponsibility to consider and discuss our major financial risk exposures and the steps our management has taken to monitor and control these exposures,including guidelines and policies to govern the process by which risk assessment and management is undertaken.

Any stockholder may recommend nominees for director by writing toDr. Ann F. Hanham, Ph.D., Chair of the Nominating and Governance Committee of the Board of Directors, HTG Molecular Diagnostics, Inc., 3430 E. GlobalLoop, Tucson, Arizona 85706, giving the name and address of the stockholder on whose behalf the submission is made, the number of Company shares thatare owned beneficially by such stockholder as of the date of the submission, the full name of the proposed candidate, a description of the proposedcandidate’s business experience for at least the previous five years, complete biographical information for the proposed candidate and a description of theproposed candidate’s qualifications as a director. All of these communications will be reviewed by our nominating and governance committee, for furtherreview and consideration in accordance with this policy.77 Section 16(a) Beneficial Ownership Reporting ComplianceUnder Section 16(a) of the Exchange Act, directors, officers and beneficial owners of 10% or more of our common stock are required to file with theSEC on a timely basis initial reports of beneficial ownership and reports of changes regarding their beneficial ownership of our common stock. Officers,directors and 10% beneficial owners are required by SEC regulations to furnish us with copies of all Section 16(a) forms that they file.Based solely on our review of the copies of such forms received and the written representations from certain reporting persons, we have determinedthat no officer, director or 10% beneficial owner known to us was delinquent with respect to their reporting obligations as set forth in Section 16(a) of theExchange Act during the fiscal year ended December 31, 2017.Limitation on Liability and Indemnification of Directors and OfficersOur amended and restated certificate of incorporation and bylaws limits our directors’ and officers’ liability to the fullest extent permitted underDelaware corporate law. Delaware corporate law provides that directors of a corporation will not be personally liable for monetary damages for breach of theirfiduciary duties as directors, except for liability: •for any transaction from which the director derives an improper personal benefit; •for any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law; •under Section 174 of the Delaware General Corporation Law (unlawful payment of dividends or redemption of shares); or •for any breach of a director’s duty of loyalty to the corporation or its stockholders.If the Delaware General Corporation Law is amended to authorize corporate action further eliminating or limiting the personal liability of directors orofficers, then the liability of our directors or officers shall be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law,as so amended.Delaware law and our amended and restated bylaws provide that we will, in certain situations, indemnify any person made or threatened to be made aparty to a proceeding by reason of that person’s former or present official capacity with us against judgments, penalties, fines, settlements and reasonableexpenses. Any person is also entitled, subject to certain limitations, to payment or reimbursement of reasonable expenses (including attorneys’ fees anddisbursements) in advance of the final disposition of the proceeding.In addition, we have entered, and intend to continue to enter, into separate indemnification agreements with our directors and executive officers.These agreements, among other things, require us to indemnify our directors and executive officers for certain expenses, including attorneys’ fees, judgments,fines and settlement amounts incurred by a director or executive officer in any action or proceeding arising out of their services as one of our directors orexecutive officers or as a director or executive officer of any other company or enterprise to which the person provides services at our request.We believe that these provisions in our amended and restated certificate of incorporation and amended bylaws and these indemnification agreementsare necessary to attract and retain qualified persons as directors and officers. We also maintain a directors’ and officers’ insurance policy pursuant to whichour directors and officers are insured against liability for actions taken in their capacities as directors and officers.Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or control persons, in the opinion of theSEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable. Stockholder Communications with the Board of DirectorsWe have adopted a formal process by which stockholders may communicate with our board of directors or any individual director. Stockholders whowish to communicate with our board of directors or any individual director may do so by sending written communications addressed to our Secretary at 3430E. Global Loop, Tucson, Arizona, 85706. These communications will be reviewed by our Secretary, who will determine whether the communication isappropriate for presentation to our board of directors or the relevant director. The purpose of this screening is to allow our board of directors to avoid havingto consider irrelevant or inappropriate communications (such as advertisements, solicitations and hostile communications).78 Code of EthicsWe have adopted a Code of Business Conduct and Ethics that applies to all of our officers, directors and employees. The Code of Business Conductand Ethics is available on our website at www.htgmolecular.com. If we make any substantive amendments to the Code of Business Conduct and Ethics orgrant any waiver from a provision of the code to any executive officer or director, we will promptly disclose the nature of the amendment or waiver on ourwebsite.Item 11.

The foregoing amounts paid in recognition of 2016 corporateperformance were performance-based bonuses for 2016 that would have been reflected as non-equity incentive plan compensation for 2016 in thetable above, but for the fact that payment of these amounts was made expressly conditioned on the achievement of a 2017 financing goal andcontinued employment through completion of the financing transaction(s), as described in note (4) below.(2)The dollar amounts in this column represent the aggregate grant date fair value of RSU awards granted in 2017 and 2016, as applicable.

Theseamounts have been computed in accordance with FASB ASC Topic 718, using the Black-Scholes option pricing model. For a discussion of valuationassumptions, see Note 12 “Stock-based Compensation” to our financial statements included elsewhere in this Annual Report on Form 10-K.(4)Amounts shown represent annual performance-based bonuses earned for 2017 and 2016.

Because payment of the performance-based bonuses for 2016 was made expresslyconditioned on the achievement of the foregoing financing goal, the non-equity incentive plan compensation reportable for 2016 for each namedexecutive officer is $0, and the performance-based bonuses paid with respect to 2016 are reflected as a bonus as described in note (1) above. For moreinformation, see below under “Annual Performance-Based Bonus Opportunity.”79 (5)Amount shown represents premiums for life, disability and accidental death and dismemberment insurance paid by us on behalf of the namedexecutive officer and reimbursement to the named executive officers of the employee portion of taxes paid at the vesting of the RSU awards grantedon August 26, 2016 which vested in February and August of 2017.Annual Base SalaryThe base salary of our named executive officers is generally set forth in each officer’s employment letter agreement with us and periodically reviewedand adjusted as necessary by our board of directors, based on the recommendation of the compensation committee of our board of directors.

In March 2017, the base salaries for Mr. Johnson, Mr. Lubniewski and Mr. McMeans were increased to $412,000, $308,358 and $258,300,respectively.Annual Performance-Based Bonus OpportunityIn addition to base salaries, our named executive officers are eligible to receive annual performance-based bonuses, which are designed to provideappropriate incentives to our executives to achieve defined annual corporate goals and to reward our executives for individual achievement towards thesegoals. The annual performance-based bonus each named executive officer is eligible to receive is generally based on the extent to which we achieve thecorporate goals that our board of directors establishes each year. At the end of the year, our board of directors reviews our performance against each corporategoal and approves the extent to which we achieved each of our corporate goals.Our board of directors will generally consider each named executive officer’s individual contributions towards reaching our annual corporate goalsbut does not typically establish specific individual goals for our named executive officers. There is no minimum bonus percentage or amount established forthe named executive officers and, thus, the bonus amounts vary from year to year based on corporate and individual performance. For 2017, Mr. Johnson waseligible to receive a target bonus of up to 50% of his base salary pursuant to the terms of his employment letter agreement described below. For 2017,Mr. Lubniewski was eligible to receive a target bonus of up to 40% of his base salary pursuant to the terms of his employment letter agreement describedbelow. For 2017, Mr. McMeans was eligible to receive a target bonus of up to 40% of his base salary pursuant to the terms of his employment letteragreement described below.The corporate goals established by our board of directors for 2017 were based upon commercial and financial goals.

The financial goals were weighted at 60% towards overall corporate goal achievement and the commercial goals were weighted at 40% towardsoverall corporate goal achievement. There was no minimum percentage of corporate goals that was required to be achieved to earn a bonus. No specificindividual goals were established for any of our named executive officers for 2017.In January 2018, our board of directors determined that the 2017 corporate goals had been achieved at an aggregate level of 130%. As a result, onJanuary 25, 2018, our board of directors awarded the following bonuses to our named officers: Executive Officer Title 2017 BonusAmount Timothy B. Johnson President and Chief Executive Officer $267,800 John L. Lubniewski Senior Vice President and Chief Business Officer $160,346 Shaun D. McMeans Senior Vice President and Chief Financial Officer $134,316In January 2017, our board of directors determined that the 2016 corporate goals had been achieved at an aggregate level of 47.5%; however, at thattime, the board of directors deferred a decision on specific recommendations for individual 2016 executive officer bonuses to a future date.

This financing goal was achieved in May 2017.Equity-Based Incentive AwardsOur equity-based incentive awards are designed to align our interests with those of our employees and consultants, including our named executiveofficers. Our board of directors or any authorized committee thereof is responsible for approving equity grants, which include to date, stock options andRSUs. Vesting of the stock option and RSU awards is tied to continuous service with us and serves as an additional retention measure. Our executivesgenerally are awarded an initial stock option grant upon commencement of employment. Additional equity awards may occur periodically to specificallyincentivize executives to achieve certain corporate goals or to reward executives for exceptional performance. As of December 31, 2017, our namedexecutive officers have been granted both stock option awards and RSUs.Prior to the initial public offering, we granted all equity awards pursuant to the 2011 Plan and the 2001 Plan. All equity awards granted since ourinitial public offering have been granted pursuant to the 2014 Plan, the terms of which are described below under “—Equity Benefit Plans.” All stock optionsare granted with a per share exercise price equal to no less than the fair market value of a share of our common stock on the date of the grant of such award.Generally, our stock option awards vest over a one to four-year period subject to the holder’s continuous service to us and may be granted with anearly exercise feature. Such early exercise feature allows the holder to exercise and receive unvested shares of our stock, so that the holder may have a greateropportunity for gains on the shares to be taxed at long-term capital gains rates rather than ordinary income rates. From time to time as our board of directorsconsiders appropriate, we may grant stock options or RSUs that vest upon achievement of performance goals.Agreements with Named Executive OfficersWe have entered into letter agreements with each of our named executive officers.

The 2014 Plan becameeffective on May 5, 2015 in connection with our initial public offering.Stock Awards. The 2014 Plan provides for the grant of incentive stock options (“ISOs”), nonstatutory stock options (“NSOs”), stock appreciationrights, restricted stock awards, restricted stock unit awards, performance-based stock awards, and other forms of equity compensation (collectively “stockawards”), all of which may be granted to employees, including officers, non-employee directors and consultants of us and our affiliates. Additionally, the2014 Plan provides for the grant of performance cash awards. ISOs may be granted only to employees. All other awards may be granted to employees,including officers, and to non-employee directors and consultants.Share Reserve. Initially, the aggregate number of shares of our common stock that may be issued pursuant to stock awards under the 2014 Plan was thesum of (1) 925,616 shares, plus (2) the number of shares (not to exceed 608,819 shares) (i) reserved for issuance under our 2011 Plan at the time the 2014 Planbecame effective, and (ii) any shares subject to outstanding stock options or other stock awards that were granted under our 2011 Plan or 2001 Plan that, onor after the effective date of the 2014 Plan, are forfeited, terminate, expire or are otherwise not issued. Additionally, the number of shares of our common stockreserved for issuance under the 2014 Plan automatically increases on January 1 of each year, beginning on January 1, 2016 and continuing through andincluding January 1, 2024, by 4% of the total number of shares of our capital stock outstanding on December 31 of the preceding calendar year, or a lessernumber of shares determined by our board of directors. The maximum number of shares of our common stock that may be issued upon the exercise of ISOsunder the 2014 Plan is 1,800,000 shares.No person may be granted stock awards covering more than 200,000 shares of our common stock under the 2014 Plan during any calendar yearpursuant to stock options, stock appreciation rights and other stock awards whose value is determined by reference to an increase over an exercise or strikeprice of at least 100% of the fair market value on the date the stock award is granted. Additionally, no person may be granted in a calendar year a performancestock award covering more than 200,000 shares of our common stock or a performance cash award having a maximum value in excess of $2,000,000. Suchlimitations were designed to help assure that any deductions to which we would otherwise be entitled with respect to such awards would not be subject to the$1,000,000 limitation on the income tax deductibility of compensation paid to any covered executive officer imposed by Section 162(m) of the Code. Theexemption from the deduction limit under Section 162(m) of the Code for “performance-based compensation” has been repealed, effective for taxable yearsbeginning after December 31, 2017.If a stock award granted under the 2014 Plan expires or otherwise terminates without being exercised in full, or is settled in cash, the shares of ourcommon stock not acquired pursuant to the stock award again will become available for subsequent issuance under the 2014 Plan. In addition, the followingtypes of shares of our common stock under the 2014 Plan may become available for the grant of new stock awards under the 2014 Plan: (1) shares that areforfeited to or repurchased by us prior to becoming fully vested; (2) shares withheld to satisfy income or employment withholding taxes; or (3) shares used topay the exercise or purchase price of a stock award. Shares issued under the 2014 Plan may be previously unissued shares or reacquired shares bought by uson the open market. As of December 31, 2017, option awards covering an aggregate of 1,064,200 shares of our common stock have been granted under the2014 Plan and were outstanding and an additional 26,666 RSU awards have been granted and remain outstanding and unvested.Administration. Our board of directors, or a duly authorized committee thereof, has the authority to administer the 2014 Plan. Our board of directorsmay also delegate to one or more of our officers the authority to (1) designate employees (other than other officers) to be recipients of certain stock awards,and (2) determine the number of shares of common stock to be subject to such stock awards. Subject to the terms of the 2014 Plan, our board of directors orthe authorized committee, referred to herein as the plan administrator, determines recipients, dates of grant, the numbers and types of stock awards to begranted and the terms and conditions of the stock awards, including the period of their exercisability, vesting schedule and change of control provisionapplicable to a stock award, if any. Subject to the limitations set forth below, the plan administrator will also determine the exercise price, strike price orpurchase price of awards granted and the types of consideration to be paid for the award.The plan administrator has the authority to modify outstanding awards under the 2014 Plan. Subject to the terms of the 2014 Plan, the planadministrator has the authority to reduce the exercise, purchase or strike price of any outstanding stock award, cancel any outstanding stock award inexchange for new stock awards, cash or other consideration, or take any other action that is treated as a repricing under generally accepted accountingprinciples, with the consent of any adversely affected participant.84 Stock Options. ISOs and NSOs are granted pursuant to stock option agreements adopted by the plan administrator. The plan administrator determinesthe exercise price for a stock option, within the terms and conditions of the 2014 Plan, provided that the exercise price of a stock option generally cannot beless than 100% of the fair market value of our common stock on the date of grant. Stock options granted under the 2014 Plan vest at the rate specified by theplan administrator.The plan administrator determines the term of stock options granted under the 2014 Plan, up to a maximum of ten years. Unless the terms of anoptionholder’s stock option agreement provide otherwise, if an optionholder’s service relationship with us, or any of our affiliates, ceases for any reason otherthan disability, death or cause, the optionholder may generally exercise any vested options for a period of three months following the cessation of service.The option term may be extended in the event that exercise of the option following such a termination of service is prohibited by applicable securities lawsor our insider trading policy. If an optionholder’s service relationship with us or any of our affiliates ceases due to disability or death, or an optionholder dieswithin a certain period following cessation of service, the optionholder or a beneficiary may generally exercise any vested stock options for a period of 12months in the event of disability and 18 months in the event of death. In the event of a termination for cause, stock options generally terminate immediatelyupon the termination of the individual for cause. In no event may an option be exercised beyond the expiration of its term.Acceptable consideration for the purchase of common stock issued upon the exercise of a stock option will be determined by the plan administratorand may include (1) cash, check, bank draft or money order, (2) a broker-assisted cashless exercise, (3) the tender of shares of our common stock previouslyowned by the optionholder, (4) a net exercise of the option if it is an NSO, and (5) other legal consideration approved by the plan administrator.Unless the plan administrator provides otherwise, stock options generally are not transferable except by will, the laws of descent and distribution, orpursuant to a domestic relations order. An optionholder may designate a beneficiary, however, who may exercise the option following the optionholder’sdeath.Tax Limitations on Incentive Stock Options. The aggregate fair market value, determined at the time of grant, of our common stock with respect toISOs that are exercisable for the first time by an optionholder during any calendar year under all of our stock plans may not exceed $100,000. Stock optionsor portions thereof that exceed such limit will generally be treated as NSOs. No ISO may be granted to any person who, at the time of the grant, owns or isdeemed to own stock possessing more than 10% of our total combined voting power or that of any of our affiliates unless (1) the option exercise price is atleast 110% of the fair market value of the stock subject to the option on the date of grant, and (2) the term of the ISO does not exceed five years from the dateof grant.Restricted Stock Awards. Restricted stock awards may be granted pursuant to restricted stock award agreements adopted by the plan administrator.Restricted stock awards may be granted in consideration for (1) cash, check, bank draft or money order, (2) services rendered to us or our affiliates, or (3) anyother form of legal consideration. Common stock acquired under a restricted stock award may, but need not, be subject to a share repurchase option in ourfavor in accordance with a vesting schedule to be determined by the plan administrator. A restricted stock award may be transferred only upon such terms andconditions as set by the plan administrator. Except as otherwise provided in the applicable award agreement, restricted stock awards that have not vested maybe forfeited or repurchased by us upon the participant’s cessation of continuous service for any reason.Restricted Stock Unit Awards. Restricted stock unit awards are granted pursuant to restricted stock unit award agreements adopted by the planadministrator. RSUs may be granted in consideration for any form of legal consideration. An RSU award may be settled by cash, delivery of stock, acombination of cash and stock as deemed appropriate by the plan administrator, or in any other form of consideration set forth in the restricted stock unitaward agreement. RSUs typically vest and underlying shares of common stock are delivered as outlined in the applicable RSU agreements following thegrantee’s satisfaction of minimum statutory employee tax withholding requirements, where applicable. Employee RSU agreements generally provide thatvesting is accelerated only in certain circumstances, that delivery of the underlying shares of common stock is conditioned on the grantee’s satisfying certainvesting conditions outlined in the award, and that the grantee’s employment continue with the Company through the vesting date. Additionally, dividendequivalents may be credited in respect of shares covered by an RSU award. Except as otherwise provided in the applicable award agreement, RSUs that havenot vested will be forfeited upon the participant’s cessation of continuous service for any reason.Stock Appreciation Rights. Stock appreciation rights are granted pursuant to stock appreciation grant agreements adopted by the plan administrator.The plan administrator determines the strike price for a stock appreciation right, which generally cannot be less than 100% of the fair market value of ourcommon stock on the date of grant. Upon the exercise of a stock appreciation right, we will pay the participant an amount equal to the product of (1) theexcess of the per share fair market value of our common stock on the date of exercise over the strike price, multiplied by (2) the number of shares of commonstock with respect to which the stock appreciation right is exercised. A stock appreciation right granted under the 2014 Plan vests at the rate specified in thestock appreciation right agreement as determined by the plan administrator.85 The plan administrator determines the term of stock appreciation rights granted under the 2014 Plan, up to a maximum of ten years. Unless the terms ofa participant’s stock appreciation right agreement provide otherwise, if a participant’s service relationship with us or any of our affiliates ceases for anyreason other than cause, disability or death, the participant may generally exercise any vested stock appreciation right for a period of three months followingthe cessation of service. The stock appreciation right term may be further extended in the event that exercise of the stock appreciation right following such atermination of service is prohibited by applicable securities laws. If a participant’s service relationship with us, or any of our affiliates, ceases due to disabilityor death, or a participant dies within a certain period following cessation of service, the participant or a beneficiary may generally exercise any vested stockappreciation right for a period of 12 months in the event of disability and 18 months in the event of death. In the event of a termination for cause, stockappreciation rights generally terminate immediately upon the occurrence of the event giving rise to the termination of the individual for cause. In no eventmay a stock appreciation right be exercised beyond the expiration of its term.Performance Awards. The 2014 Plan permits the grant of performance-based stock and cash awards that, prior to the repeal of the exemption from thededuction limit under Section 162(m) of the Code for “performance-based compensation,” could qualify as performance-based compensation that is notsubject to the $1,000,000 limitation on the income tax deductibility of compensation paid to a covered executive officer imposed by Section 162(m) of theCode.The performance goals that may be selected include one or more of the following: (1) earnings (including earnings per share and net earnings);(2) earnings before interest, taxes and depreciation; (3) earnings before interest, taxes, depreciation and amortization; (4) earnings before interest, taxes,depreciation, amortization and legal settlements; (5) earnings before interest, taxes, depreciation, amortization, legal settlements and other income (expense);(6) earnings before interest, taxes, depreciation, amortization, legal settlements, other income (expense) and stock-based compensation; (7) earnings beforeinterest, taxes, depreciation, amortization, legal settlements, other income (expense), stock-based compensation and changes in deferred revenue; (8) earningsbefore interest, taxes, depreciation, amortization, legal settlements, other income (expense), stock-based compensation, other non-cash expenses and changesin deferred revenue; (9) total stockholder return; (10) return on equity or average stockholder’s equity; (11) return on assets, investment, or capital employed;(12) stock price; (13) margin (including gross margin); (14) income (before or after taxes); (15) operating income; (16) operating income after taxes; (17) pre-tax profit; (18) operating cash flow; (19) sales or revenue targets; (20) increases in revenue or product revenue; (21) expenses and cost reduction goals;(22) improvement in or attainment of working capital levels; (23) economic value added (or an equivalent metric); (24) market share; (25) cash flow;(26) cash flow per share; (27) cash balance; (28) cash burn; (29) cash collections; (30) share price performance; (31) debt reduction; (32) implementation orcompletion of projects or processes (including, without limitation, clinical study initiation, clinical study enrollment and dates, clinical study results,regulatory filing submissions, regulatory filing acceptances, regulatory or advisory committee interactions, regulatory approvals, and product supply);(33) stockholders’ equity; (34) capital expenditures; (35) debt levels; (36) operating profit or net operating profit; (37) workforce diversity; (38) growth of netincome or operating income; (39) billings; (40) bookings; (41) employee retention; (42) initiation of studies by specific dates; (43) budget management;(44) submission to, or approval by, a regulatory body (including, but not limited to the FDA) of an applicable filing or a product; (45) regulatory milestones;(46) progress of internal research or development programs; (47) acquisition of new customers; (48) customer retention and/or repeat order rate;(49) improvements in sample and test processing times; (50) progress of partnered programs; (51) partner satisfaction; (52) timely completion of clinicalstudies; (53) submission of 510(k)s or pre-market approvals and other regulatory achievements; (54) milestones related to samples received and/or tests orpanels run; (55) expansion of sales in additional geographies or markets; (56) research progress, including the development of programs; (57) strategicpartnerships or transactions (including in-licensing and out-licensing of intellectual property); and (58) to the extent that an award is not intended to complywith Section 162(m) of the Code, other measures of performance selected by our board of directors.The performance goals may be based on a company-wide basis, with respect to one or more business units, divisions, affiliates, or business segments,and in either absolute terms or relative to the performance of one or more comparable companies or the performance of one or more relevant indices. Unlessspecified otherwise (i) in the award agreement at the time the award is granted or (ii) in such other document setting forth the performance goals at the timethe goals are established, we will appropriately make adjustments in the method of calculating the attainment of performance goals as follows: (1) to excluderestructuring and/or other nonrecurring charges; (2) to exclude exchange rate effects; (3) to exclude the effects of changes to generally accepted accountingprinciples; (4) to exclude the effects of any statutory adjustments to corporate tax rates; (5) to exclude the effects of any “extraordinary items” as determinedunder generally accepted accounting principles; (6) to exclude the dilutive effects of acquisitions or joint ventures; (7) to assume that any business divestedby us achieved performance objectives at targeted levels during the balance of a performance period following such divestiture; (8) to exclude the effect ofany change in the outstanding shares of our common stock by reason of any stock dividend or split, stock repurchase, reorganization, recapitalization,merger, consolidation, spin-off, combination or exchange of shares or other similar corporate change, or any distributions to common stockholders other thanregular cash dividends; (9) to exclude the effects of stock-based compensation and the award of bonuses under our bonus plans; (10) to exclude costsincurred in connection with potential acquisitions or divestitures that are required to be expensed under generally accepted accounting principles; (11) toexclude the goodwill and intangible asset impairment charges that are required to be recorded under generally accepted accounting principles; (12) toexclude the effect of any other unusual, non-recurring gain or loss or other86 extraordinary item; and (13) to exclude the effects of the timing of acceptance for review and/or approval of submissions to the FDA or any other regulatorybody. In addition, we retain the discretion to reduce or eliminate the compensation or economic benefit due upon attainment of the performance goals and todefine the manner of calculating the performance criteria we select to use for such performance period. The performance goals may differ from participant toparticipant and from award to award.Other Stock Awards. The plan administrator may grant other awards based in whole or in part by reference to our common stock. The planadministrator will set the number of shares under the stock award and all other terms and conditions of such awards.Changes to Capital Structure. In the event that there is a specified type of change in our capital structure, such as a stock split or recapitalization,appropriate adjustments will be made to (1) the class and maximum number of shares reserved for issuance under the 2014 Plan, (2) the class and maximumnumber of shares by which the share reserve may increase automatically each year, (3) the class and maximum number of shares that may be issued upon theexercise of ISOs, (4) the class and maximum number of shares subject to stock awards that can be granted in a calendar year (as established under the 2014Plan pursuant to Section 162(m) of the Code) and (5) the class and number of shares and exercise price, strike price, or purchase price, if applicable, of alloutstanding stock awards.Corporate Transactions. In the event of certain specified significant corporate transactions, the plan administrator has the discretion to take any of thefollowing actions with respect to stock awards: •arrange for the assumption, continuation or substitution of a stock award by a surviving or acquiring entity or parent company; •arrange for the assignment of any reacquisition or repurchase rights held by us to the surviving or acquiring entity or parent company; •accelerate the vesting of the stock award and provide for its termination at or prior to the effective time of the corporate transaction; •arrange for the lapse of any reacquisition or repurchase right held by us; •cancel or arrange for the cancellation of the stock award in exchange for such cash consideration, if any, as our board of directors may deemappropriate; or •make a payment equal to the excess of (1) the value of the property the participant would have received upon exercise of the stock award over(2) the exercise price otherwise payable in connection with the stock award.Our plan administrator is not obligated to treat all stock awards, even those that are of the same type, in the same manner.Under the 2014 Plan, a corporate transaction is generally the consummation of (1) a sale or other disposition of all or substantially all of our assets,(2) a sale or other disposition of at least 90% of our outstanding securities, (3) a merger, consolidation or similar transaction following which we are not thesurviving corporation, or (4) a merger, consolidation or similar transaction following which we are the surviving corporation but the shares of our commonstock outstanding immediately prior to such transaction are converted or exchanged into other property by virtue of the transaction.Change of Control. The plan administrator may provide, in an individual award agreement or in any other written agreement between a participantand us that the stock award will be subject to additional acceleration of vesting and exercisability in the event of a change of control. For example, certain ofour employees may receive an award agreement that provides for vesting acceleration upon the individual’s termination without cause or resignation forgood reason (including a material reduction in the individual’s base salary, duties, responsibilities or authority, or a material relocation of the individual’sprincipal place of employment with us) in connection with a change of control. Under the 2014 Plan, a change of control is generally (1) the acquisition by aperson or entity of more than 50% of our combined voting power other than by merger, consolidation or similar transaction; (2) a consummated merger,consolidation or similar transaction immediately after which our stockholders cease to own more than 50% of the combined voting power of the survivingentity; (3) a consummated sale, lease or exclusive license or other disposition of all or substantially of our assets; or (4) our stockholders approve a plan ofour complete dissolution or liquidation or our complete dissolution or liquidation otherwise occurs.All stock options granted under the 2014 Plan to our named executive officers provide that vesting and exercisability of such stock options will beaccelerated in full following a change in control if, immediately prior to or within 12 months after the effective time of such change in control, theoptionholder’s continuous service terminates due to an involuntary termination without cause or due to a voluntary termination with good reason. Severalterms are specifically defined in the 2014 Plan for purposes of this “double-trigger” provision; in particular, (i) “good reason” is generally defined as (1) amaterial reduction in the optionholder’s annual base salary, except pursuant to a salary reduction program affecting substantially all of our employees thatdoes not disproportionately87 affect the optionholder; (2) a material reduction in the optionholder’s authority, duties or responsibilities; (3) any failure by us to continue any materialbenefit plan or program in which the optionholder was participating immediately prior to the change in control, or any action by us that would adverselyaffect the optionholder’s participation in or reduce his/her benefits under such benefit plan or program, or deprive him/her of any fringe benefit enjoyedimmediately prior to the change in control, unless, taken as a whole, we provide for optionholder participation in comparable benefit plans or programs; (4) arelocation of the optionholder’s principal place of employment more than 50 miles; or (5) a material breach by us of any provision of the 2014 Plan or anoption agreement under the 2014 Plan or any other material agreement between the optionholder and us concerning the terms and conditions of employmentor service with us; and (ii) “cause” is generally defined as the occurrence of any of the following events: (A) the optionholder’s commission of any felony orany crime involving fraud, dishonesty or moral turpitude under the laws of the United States or any state thereof; (B) the optionholder’s attemptedcommission of, or participation in, a fraud or act of dishonesty against us; (C) the optionholder’s intentional, material violation of any contract or agreementbetween the optionholder and us or of any statutory duty owed to us; (D) the optionholder’s unauthorized use or disclosure of our confidential information ortrade secrets; or (E) the optionholder’s gross misconduct.Amendment and Termination. Our board of directors has the authority to amend, suspend, or terminate the 2014 Plan, provided that such action doesnot materially impair the existing rights of any participant without such participant’s written consent. No ISOs may be granted after the tenth anniversary ofthe date our board of directors adopted the 2014 Plan.2011 Equity Incentive PlanGeneral. Our board of directors and our stockholders approved our 2011 Plan in March 2011. The 2011 Plan was subsequently amended by our boardof directors and our stockholders, most recently in February 2014. The 2011 Plan is the successor to and continuation of our 2001 Plan. As of December 31,2017, option awards under the 2011 Plan covering an aggregate of 383,020 shares of our common stock were outstanding. No additional awards will begranted under the 2011 Plan and all outstanding awards granted under the 2011 Plan that are repurchased, forfeited, expire or are cancelled will becomeavailable for grant under the 2014 Plan in accordance with its terms. Our board of directors, or a duly authorized committee thereof, has the authority toadminister the 2011 Plan. Our board of directors may also delegate certain authority to one or more of our officers. The plan administrator has the authority tomodify outstanding awards under our 2011 Plan, including the authority to reduce the exercise, purchase or strike price of any outstanding stock award,cancel any outstanding stock award in exchange for new stock awards, cash or other consideration, or take any other action that is treated as a repricing undergenerally accepted accounting principles, with the consent of any adversely affected participant.Stock Options. ISOs and NSOs are granted pursuant to stock option agreements adopted by the plan administrator. The plan administrator determinesthe exercise price for a stock option, within the terms and conditions of the 2011 Plan, provided that the exercise price of a stock option generally cannot beless than 100% of the fair market value of our common stock on the date of grant. Stock options granted under the 2011 Plan vest at the rate specified by theplan administrator.The plan administrator determines the term of stock options granted under the 2011 Plan, up to a maximum of 10 years. Unless the terms of anoptionholder’s stock option agreement provide otherwise, if an optionholder’s service relationship with us, or any of our affiliates, ceases for any reason otherthan disability, death or cause, the optionholder may generally exercise any vested stock options for a period of three months following the cessation ofservice. The stock option term may be extended in the event that exercise of the option following such a termination of service is prohibited by applicablesecurities laws or our insider trading policy. If an optionholder’s service relationship with us or any of our affiliates ceases due to disability or death, or anoptionholder dies within a certain period following cessation of service, the optionholder or a beneficiary may generally exercise any vested stock optionsfor a period of 12 months in the event of disability and 18 months in the event of death. In the event of a termination for cause, stock options generallyterminate immediately upon the termination of the individual for cause. In no event may an option be exercised beyond the expiration of its term.Corporate Transactions. Unless otherwise provided in a stock award agreement or other written agreement between us and a participant, in the eventof certain specified significant corporate transactions, the plan administrator has the discretion to take any of the following actions with respect to stockawards: •arrange for the assumption, continuation or substitution of a stock award by a surviving or acquiring entity or parent company; •arrange for the assignment of any reacquisition or repurchase rights held by us to the surviving or acquiring entity or parent company;88 •accelerate the vesting, in whole or in part, of the stock award and provide for its termination prior to the effective time of the corporatetransaction; •arrange for the lapse of any reacquisition or repurchase right held by us; •cancel or arrange for the cancellation of the stock award in exchange for such cash consideration, if any, as our board of directors may deemappropriate; or •make a payment equal to the excess of (a) the value of the property the participant would have received upon exercise of the stock award over(b) the exercise price otherwise payable in connection with the stock award.Our plan administrator is not obligated to treat all stock awards, even those that are of the same type, in the same manner.Under the 2011 Plan, a corporate transaction is generally defined as the consummation of (1) a sale or other disposition of all or substantially all of ourassets, (2) a sale or other disposition of at least 90% of our outstanding securities, (3) a merger, consolidation or similar transaction following which we arenot the surviving corporation, or (4) a merger, consolidation or similar transaction following which we are the surviving corporation but the shares of ourcommon stock outstanding immediately prior to such transaction are converted or exchanged into other property by virtue of the transaction.Change of Control. The plan administrator may provide, in an individual award agreement or in any other written agreement between a participantand us that the stock award will be subject to additional acceleration of vesting and exercisability in the event of a change of control. Under the 2011 Plan, achange of control is generally defined as (1) the acquisition by a person or entity of more than 50% of our combined voting power other than by merger,consolidation or similar transaction, (2) a consummated merger, consolidation or similar transaction immediately after which our stockholders cease to ownmore than 50% of the combined voting power of the surviving entity, (3) approval by the stockholders or our board of directors of a plan of completedissolution or liquidation of us or our complete dissolution or liquidation occurs or (4) a consummated sale, lease or exclusive license or other disposition ofall or substantially of our assets.Certain stock options granted under the 2011 Plan, including the stock options held by our named executive officers, provide that if immediatelyprior to a change of control the participant’s service with the Company has not terminated, the option will accelerate vesting with respect to 25% of the then-unvested portion of the option; if the option continues, the remaining 75% of the unvested option will continue to vest on the option’s original scheduleprior to the change of control and will accelerate vesting in full in the event that the participant’s continuous service is terminated without cause or by theparticipant for good reason within the 12 months following the change of control. “Good reason” for purposes of this “double-trigger” provision is generallydefined as (1) an assignment of duties or responsibilities to the participant that results in a material diminution of the participant’s function; (2) a materialreduction in the participant’s annual base salary; (3) failure to continue the participant’s benefit plans or programs, any action that would adversely affect theparticipant’s participation in any benefit plan, reduce the participant’s benefits under any benefit plan or deprive the participant of any fringe benefit; or (4) arelocation of the participant’s business office more than 50 miles.2001 Stock Option PlanOur board of directors and our stockholders approved our 2001 Plan, which became effective in February 2001. The 2001 Plan terminated and nofurther awards were granted under the 2001 Plan upon the effective date of the 2011 Plan. As of December 31, 2017, there were outstanding stock optionsunder our 2001 Plan covering a total of 70,551 shares of our common stock.2014 Employee Stock Purchase PlanGeneral. Our board of directors adopted the ESPP in December 2014 and our stockholders approved the ESPP in April 2015. The ESPP becameeffective on May 5, 2015 in connection with our initial public offering. The purpose of the ESPP is to retain the services of new employees and secure theservices of new and existing employees while providing incentives for such individuals to exert maximum efforts toward our success and that of our affiliates.The ESPP is intended to qualify as an “employee stock purchase plan” within the meaning of Section 423 of the Code. As of the date hereof, no shares of ourcommon stock have been purchased under the ESPP. Our board of directors has delegated its authority to administer the ESPP to our compensationcommittee.The ESPP initially authorized the issuance of 110,820 shares of our common stock pursuant to purchase rights granted to our employees or toemployees of any of our designated affiliates. The number of shares of our common stock reserved for issuance automatically increases on January 1 of eachcalendar year, from January 1, 2016 through January 1, 2024 by the least of (1) 1% of the total number of shares of our common stock outstanding onDecember 31 of the preceding calendar year, (2) 195,000 shares, or (3) a number determined by our board of directors that is less than (1) and (2).89 Offerings and Purchases. The ESPP is implemented through a series of offerings of purchase rights to eligible employees. Under the ESPP, we mayspecify offerings with durations of not more than 27 months, and may specify shorter purchase periods within each offering. Each offering will have one ormore purchase dates on which shares of our common stock will be purchased for employees participating in the offering. Generally, all regular employees,including executive officers, subject to certain restrictions, employed by us or by any of our designated affiliates, may participate in the ESPP and maycontribute, normally through payroll deductions, up to 15% of their earnings for the purchase of our common stock under the ESPP. Unless otherwisedetermined by our board of directors, common stock will be purchased for accounts of employees participating in the ESPP at a price per share equal to thelower of (1) 85% of the fair market value of a share of our common stock on the first date of an offering or (2) 85% of the fair market value of a share of ourcommon stock on the date of purchase.Changes to Capital Structure. In the event that there occurs a change in our capital structure through such actions as a stock split, merger,consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, large nonrecurring cash dividend,liquidating dividend, combination of shares, exchange of shares, change in corporate structure or similar transaction, the board of directors will makeappropriate adjustments to (1) the number of shares reserved under the ESPP, (2) the maximum number of shares by which the share reserve may increaseautomatically each year and (3) the number of shares and purchase price of all outstanding purchase rights.Corporate Transactions. In the event of certain significant corporate transactions, including the consummation of: (1) a sale of all our assets, (2) thesale or disposition of 90% of our outstanding securities, (3) a merger or consolidation where we do not survive the transaction and (4) a merger orconsolidation where we do survive the transaction but the shares of our common stock outstanding immediately prior to such transaction are converted orexchanged into other property by virtue of the transaction, any then-outstanding rights to purchase our stock under the ESPP may be assumed, continued orsubstituted for by any surviving or acquiring entity (or its parent company). If the surviving or acquiring entity (or its parent company) elects not to assume,continue or substitute for such purchase rights, then the participants’ accumulated payroll contributions will be used to purchase shares of our common stockwithin ten business days prior to such corporate transaction, and such purchase rights will terminate immediately.Plan Amendments, Termination. Our board of directors has the authority to amend or terminate our ESPP, provided that except in certaincircumstances any such amendment or termination may not materially impair any outstanding purchase rights without the holder’s consent. We will obtainstockholder approval of any amendment to our ESPP as required by applicable law or listing requirements.401(k) PlanWe maintain a tax-qualified retirement plan that provides eligible employees with an opportunity to save for retirement on a tax advantaged basis. Allparticipants’ interests in their deferrals are 100% vested when contributed. In 2017, we made no matching contributions into the 401(k) plan. Pre-taxcontributions are allocated to each participant’s individual account and are then invested in selected investment alternatives according to the participants’directions. The 401(k) plan is intended to qualify under Sections 401(a) and 501(a) of the Code. As a tax-qualified retirement plan, contributions to the401(k) plan and earnings on those contributions are not taxable to the employees until distributed from the 401(k) plan, and all contributions are deductibleby us when made.Director CompensationThe following table sets forth in summary form information concerning the compensation that we paid or awarded during the year ended December 31,2017 to each of our non-employee directors: Name Fees Earned ($) Option Awards($) (1) Total ($) Ann F.

Certain Relationships and Related Transactions, and Director Independence.We have adopted a written related-person transactions policy that sets forth our policies and procedures regarding the identification, review,consideration and oversight of “related-person transactions.” For purposes of our policy only, a “related-person transaction” is a transaction, arrangement orrelationship (or any series of similar transactions, arrangements or relationships) in which we and any “related person” are participants involving an amountthat exceeds the lesser of $120,000 or one percent of the average of the Company’s total assets at year-end for the last two completed fiscal years.Transactions involving compensation for services provided to us as an employee, consultant or director are not considered related-person transactionsunder this policy. A “related person” is any executive officer, director or a holder of more than five percent of our common stock, including any of theirimmediate family members and any entity owned or controlled by such persons.Under the policy, where a transaction has been identified as a related-person transaction, management must present information regarding theproposed related-person transaction to our audit committee (or, where review by our audit committee would be inappropriate, to another independent body ofour board of directors) for review. The presentation must include a description of, among other things, the material facts, the direct and indirect interests ofthe related persons, the benefits of the transaction to us and93 whether any alternative transactions are available. To identify related-person transactions in advance, we rely on information supplied by our executiveofficers, directors and certain significant stockholders. In considering related-person transactions, our audit committee or other independent body of ourboard of directors takes into account the relevant available facts and circumstances including, but not limited to: •the risks, costs and benefits to us; •the impact on a director’s independence in the event the related person is a director, immediate family member of a director or an entity withwhich a director is affiliated; •the terms of the transaction; •the availability of other sources for comparable services or products; and •the terms available to or from, as the case may be, unrelated third parties or to or from our employees generally.In the event a director has an interest in the proposed transaction, the director must recuse himself or herself from the deliberations and approval.The following sections summarize transactions since January 1, 2016 to which we have been a party, in which the amount involved in the transactionexceeded the lesser of $120,000 or one percent of the average of the Company’s total assets at year-end for the last two completed fiscal years, and in whichany of our directors, executive officers or, to our knowledge, beneficial owners of more than 5% of our capital stock or any member of the immediate familyof any of the foregoing persons had or will have a direct or indirect material interest, other than equity and other compensation, termination, change incontrol and other arrangements, which are described under “Executive Compensation” and “Director Compensation.”Transactions with QIAGEN Manchester Limited and AffiliatesIn November 2016, we entered into a Master Assay Development, Commercialization and Manufacturing Agreement (“Governing Agreement”) withQIAGEN Manchester Limited (“QML”), and we concurrently entered into a stock purchase agreement with QIAGEN North American Holdings, Inc.(“QNAH”). Both QML and QNAH are wholly owned subsidiaries of QIAGEN N.V. Pursuant to the shares of our common stock acquired by QNAH under thestock purchase agreement, QNAH became a greater than 5% holder of our common stock.In June 2017, we entered into a first statement of work (“SOW One”) with QML under the Governing Agreement. SOW One addresses the initialactivities to be performed by us and QML in support of the development and potential commercialization of a NGS-based companion diagnostic assay that isthe subject of a sponsor project agreement between QML and a biopharmaceutical company (“Pharma One”). QML has agreed to pay us low, single-digitmillions of dollars for the Pharma One development work performed under the SOW, and we and QML will share any net profits resulting from performance ofthe development work as determined pursuant to the Governing Agreement. For additional details regarding the terms of SOW One, please refer to Note 15 toour financial statements contained in this Annual Report.In connection with SOW One, the Governing Agreement was amended to provide that neither party may terminate SOW One or the GoverningAgreement to the extent it relates to SOW One in the event of a change of control.In October 2017, we entered into a second statement of work (“SOW Two”) under the Governing Agreement with QML. SOW Two was made effectiveas of June 2, 2017 (“Onset Date”). SOW Two addresses development activities conducted by us and QML since the Onset Date and those expected to befurther conducted by parties in connection with a sponsor project agreement, dated June 2, 2017, between QML and Bristol-Myers Squibb. QML has agreedto pay us mid-single digit millions of dollars for the development work performed and expected to be performed by us and QML under SOW Two (the “InitialPhase Work”). In addition, we will share in any net profits (as determined under the Governing Agreement) generated by the Initial Phase Work on anapproximately quarterly basis throughout the term of SOW Two. For additional details regarding the terms of SOW Two, please refer to Note 15 to ourfinancial statements contained in this Annual Report.In January 2018, we entered into a third statement of work (“SOW Three”) under the Governing Agreement with QML. SOW Three addresses thedevelopment activities for a NGS‑based clinical‑trial assay (“SOW Three Project”) in connection with a sponsor project agreement between QML and apharmaceutical company (“Pharma Three”). QML has agreed to pay us low, single-digit millions of dollars for the development work performed and expectedto be performed by us and QML under SOW Three. In addition, we will share in any net profits (as determined under the Governing Agreement) generated bythe SOW Three Project on an approximately quarterly basis over the term of SOW Three. For additional details regarding the terms of SOW Three, please referto Note 16 to our financial statements contained in this Annual Report.94 In October 2017, we issued a subordinated convertible promissory note (the “QNAH Convertible Note”) to QIAGEN North American Holdings, Inc.(“QNAH”) in the principal amount of $3.0 million against receipt of cash proceeds equal to such principal amount. The QNAH Convertible Note bears simpleinterest at the rate of 3.0% per annum and matures on October 26, 2020. Our indebtedness under the QNAH Convertible Note is expressly subordinated inright of payment to the prior repayment in full of our indebtedness under our Growth Term Loan. QNAH may elect to convert all or any portion of theoutstanding principal balance of the QNAH Convertible Note and all unpaid accrued interest thereon at any time prior to the maturity date into shares of ourcommon stock at a conversion price of $3.984 per share.Since October 26, 2017, the outstanding principal amount of the QNAH Convertible Note has remained at $3.0 million.Employment ArrangementsWe currently have written employment agreements with our executive officers. For information about our employment agreements with our namedexecutive officers, refer to “Executive Compensation – Agreements with our Named Executive Officers.”Stock Options Granted to Executive Officers and DirectorsWe have granted stock options to our executive officers and directors, as more fully described in “Executive Compensation – Outstanding EquityAwards at Fiscal Year-End.”Indemnification AgreementsWe have entered into, and intend to continue to enter into, separate indemnification agreements with our directors and executive officers, in additionto the indemnification provided for in our amended and restated bylaws. These agreements, among other things, require us to indemnify our directors andexecutive officers for certain expenses, including attorneys’ fees, judgments, fines and settlement amounts incurred by a director or executive officer in anyaction or proceeding arising out of their services as one of our directors or executive officers or any other company or enterprise to which the person providesservices at our request. We believe that these bylaw provisions and indemnification agreements are necessary to attract and retain qualified persons asdirectors and officers.The limitation of liability and indemnification provisions in our amended and restated certificate of incorporation and amended and restated bylawsmay discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duties. They may also reduce the likelihood of derivativelitigation against directors and officers, even though an action, if successful, might benefit us and our stockholders. A stockholder’s investment may beharmed to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.Director IndependenceOur board of directors has determined that all of our directors other than Mr. Johnson are independent directors, as defined by Rule 5605(a)(2) of theNasdaq Listing Rules. The Nasdaq independence definition includes a series of objective tests, including that the director is not, and has not been for at leastthree years, one of our employees and that neither the director nor any of his family members has engaged in various types of business dealings with us. Inaddition, as required by Nasdaq rules, our board of directors has made a subjective determination as to each independent director that no relationships exist,which, in the opinion of our board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Inmaking these determinations, our board of directors reviewed and discussed information provided by the directors and us with regard to each director’sbusiness and personal activities and relationships as they may relate to us and our management. 95 Item 14.
