PART I.
Item 1. Business.
References herein to “we”, “us”, “our”, or “the Company” refer to Nanosphere, Inc., unless the context specifically requires otherwise.
Overview
We develop, manufacture and market an advanced molecular diagnostics platform, the Verigene® System, that enables simple, low cost and highly sensitive genomic and protein testing on a single platform. Our proprietary nanoparticle technology provides the ability to detect multiple targets simultaneously in a single sample. We are dedicated to enhancing medicine by providing targeted molecular diagnostic tests for infectious diseases and associated drug resistance markers that can lead to earlier disease detection, optimal patient treatment and improved healthcare economics. The Verigene System includes a bench-top molecular diagnostics workstation and single use consumable for on demand testing.
We believe the Verigene System is differentiated by its ease of use, superior analytical performance and ability to detect many targets on a single test, referred to as “multiplexing”. It provides lower cost solutions for laboratories not already performing molecular diagnostic testing and enables the full range of hospital laboratories and hospitals without advanced diagnostic capabilities to perform molecular genetics and infectious disease testing. Our unique ability to detect proteins, in addition to genetic and drug resistant markers , at sensitivity levels considerably higher than current methods for certain targets, may enhancing the viability and clinical utility of both new and existing biomarkers potentially allowing for earlier detection and intervention for various disease states.
Our test offering has the potential and has been shown to improve patient outcomes compared to current culture based microbiology methods by providing rapid and clinically actionable results that can reduce mortality, reduce the use of and costs associated with unnecessary antibiotics and associated drug resistance, and improve healthcare economics
In addition to our menu of infectious disease tests, we are currently developing a next generation Verigene system that will deliver improved user experience. This system is designed to provide reduced time to result, improved user interface, including a single room temperature cartridge all in a fully automated sample to result system with an optimized footprint.
At this time, we believe our current Verigene System instrument inventory levels are sufficient to meet demand. With our next generation Verigene System in development, we will closely monitor inventory levels and forecasted sales to manage our investment to meet demand while managing the risk of obsolete inventory. A significant portion of our inventory is instruments held at outside customers for evaluation prior to purchase. These instruments may not convert to sales and may be returned to the Company. If returned, these instruments are refurbished and remain available for sale inventory. The cost basis of our inventory is reduced for any products that are considered excessive or obsolete based upon assumptions about future demands and market conditions. If actual future demands or market conditions are less favorable than those projected by management, inventory write-downs may be required.

Infectious Disease Assays

The conversion of traditional culture based methods of microbiology testing methods to more rapid molecular methods is driven by the need to identify infectious diseases more quickly, allowing a more rapid commencement of appropriate clinical intervention. Microbiology labs require tests that can rapidly detect a wide range of potential infectious agents in an automated system.

The Verigene System provides the multiplexing, rapid turnaround and ease-of-use needed by these labs. Our infectious disease menu and the Processor SP provide microbiology labs with the ability to identify infectious pathogens and antibiotic resistance in hours as compared to days using traditional methods.
We have received 510(k) clearance from the FDA for our respiratory panel that detects the presence of influenza A and B as well as respiratory syncytial virus (“RSV”) A and B. Influenza is commonly known as the seasonal flu and RSV is a respiratory virus that infects the lungs and breathing passages. RSV is the most common cause of bronchitis and pneumonia in children under the age of one year and has become a significant concern for older adults. Our respiratory panel provides physicians with a highly accurate and fast determination of which virus is present. This test result guides the most appropriate treatment therapy.
In the fourth quarter of 2009, we received 510(k) clearance from the FDA for our respiratory panel on the Processor SP. We believe that our respiratory assay on the Processor SP offers a simple-to-use molecular test for diagnosing

5


respiratory infections and the flu, while providing improved sensitivity over currently available rapid tests. Additionally, we have received clearance for a package insert change for this assay confirming that the novel H1N1 virus is detected as a positive Influenza A when using our respiratory assay and the Processor SP.
In the first quarter of 2011, we received 510(k) clearance from the FDA and obtained CE IVD Mark for our respiratory assay (RV+) that includes subtyping for seasonal H1 virus, seasonal H3 virus, and the 2009 novel H1N1 virus, commonly known as swine flu, as well as the targets on our previously cleared respiratory assay.
The RV+ test has been further expanded to include additional viral and bacterial respiratory pathogens. This expanded panel, the RP Flex assay ("RP Flex"), is designed to enable hospital-based laboratories to identify complex infections for a broader patient population. We obtained CE IVD Mark for the RP Flex in the second quarter of 2015 and received 510(k) clearance in the third quarter of 2015. The RP Flex contains a panel of 16 viral and bacterial targets and allows for the selection of any combination of targets for an individual sample. In addition, the RP Flex also provides pricing matched to the targets selected, therefore combining clinical utility with healthcare economics in a manner currently unavailable from any of our competitors. This flexible panel addresses the varied respiratory testing needs of patients, labs and clinicians with a single comprehensive, yet cost-effective solution.
Nanosphere has developed and is continuing to develop bloodstream infection panels for the earlier detection of specific bacteria and resistance markers present in patients with bloodstream infections. These panels include gram-positive, gram-negative and yeast pathogens as well as resistance markers. These assays are designed to enable physicians to detect bacterial strains infecting patients and thus prescribe the most appropriate antibiotic regimen within 2.5 hours after positive blood culture and Gram stain identification rather than after several days, which is typical for current traditional culture assays. The sensitivity and specificity of bloodstream infection tests enable clinicians to make better therapeutic decisions sooner, thus improving patient outcomes and reducing costs. Multiple treatments are often initiated before these current traditional assays are complete. This early detection capability also allows patients to avoid unnecessary treatments that may expose them to serious side effects. The first bloodstream infection panel developed was for the detection of gram-positive organisms (BC-GP) that represent approximately 65% of bloodstream infections. In June 2012, we received a de novo 510(k) clearance, representing the first ever molecular bloodstream infection test to market the full BC-GP panel. In January 2014, we received 510(k) clearance for our gram-negative ("BC-GN") assay representing approximately 35% of bloodstream infections.
Diarrhea caused by bacterial and viral infection represents a significant healthcare burden in the U.S. Since symptoms alone are insufficient to make treatment decisions, rapid identification of the bacterial or viral cause of diarrhea is critical for optimal patient management, limiting the prescription of inappropriate or unnecessary antibiotics. Nanosphere has an active program in the development of diagnostic tests for gastrointestinal/enteric infections. We developed a molecular test to detect C. difficile, a bacterium that can cause symptoms ranging from diarrhea to life-threatening inflammation of the colon. For our C. difficile test, we received 510(k) clearance from the FDA in the fourth quarter of 2012 and obtained CE IVD Mark in the first quarter of 2013.
Nanosphere has also developed a multiplexed molecular enteric pathogens (EP) test which tests for a wide spectrum of bacteria and viruses causing gastrointestinal infections. This EP test is a cost-effective alternative to conventional identification methods that are time- and labor-intensive. We received 510(k) clearance from the FDA in October 2014 for our EP test and obtained CE IVD Mark in the second quarter of 2015. In addition, we have a next generation Enteric panel that incorporates our Flex capability that will allow for user selected targets of bacterial, viral and parasitic targets all in a Flex pricing format similar to our recently cleared respiratory Flex panel. We believe these Flex panels provide clinical and economic value to laboratories, clinicians and providers.
Human and Pharmacogenetic Assays
While our core focus is in the infectious disease applications, we also offer a limited menu of human and pharmacogenetic assays on our original Verigene processor and distribute into limited customer base in the U.S. and certain international markets.
We received 510(k) clearance from the FDA for a warfarin metabolism assay performed on our Original Verigene Processor. This is a pharmacogenetic test to determine the existence of certain genetic mutations that affect the metabolism of warfarin-based drugs, including Coumadin®, the most-prescribed oral anticoagulant. CE IVD Mark was obtained for this assay during the first quarter of 2011.
We also received 510(k) clearance from the FDA for a hypercoagulation assay performed on our Original Verigene Processor. This is a human genetic test to determine the existence of certain genetic mutations that are hereditary contributory

6


factors in forming blood clots. This Verigene test detects the F5, F2, and MTHFR genes that are associated with hypercoagulation (i.e., thrombophilia). CE IVD Mark was obtained for this assay on the Processor SP during the fourth quarter of 2011.
In the fourth quarter of 2012 we received 510(k) clearance from the FDA for a CYP2C19 genetic variance test which we do not currently market in the U.S. This assay was CE IVD Marked during the first quarter of 2011 and is distributed in certain international markets. This test detects variances in the cytochrome P-450 2C19 gene. These genetic variances are associated with deficient metabolism of CYP2C19-metabolized therapeutic agents including clopidogrel, more commonly known by the trade name Plavix™.
Ultra-Sensitive and Multiplexed Protein Assays
We also have the capability to detect proteins at high sensitivity, either alone or in combination with nucleic acid targets. In the future, we may develop diagnostic tests for markers utilizing this ultra-sensitive capability that can be used to diagnose a variety of medical conditions including cardiovascular, respiratory, cancer, autoimmune, neurodegenerative and other diseases.
The Verigene System
The Verigene System consists of a microfluidics processor, a touchscreen reader and disposable test cartridges. The microfluidics processor interacts with and manipulates various functional components of the test cartridge, accomplishing a number of necessary steps, including target binding to the nucleic acid or protein array, gold nanoparticle probe hybridization, intermediate washes and signal amplification. The reader houses the optical detection module that illuminates the test slide and automated spot recognition software that analyzes the resulting signal intensities and provides the test results. The reader also serves as the control station for the Verigene System and features a simple and intuitive touchscreen interface that allows users to track samples and test cartridges, initiate and monitor test processing, analyze results and generate reports. The reader is web-enabled to allow remote access to results and reports.
To perform a test, the operator adds a prepared sample to a designated port in the test cartridge, enters sample identification and test cartridge information into the reader using the touchscreen keyboard or via the barcode wand, and inserts the test cartridge into the processor. The processor assimilates information received from the reader and matches it to the inserted test cartridge and initiates the specified test protocol. Once the assay process is complete the test array is introduced into the reader for image analysis and result reporting.
Our Technology
We believe our technology will drive broad usage of ultra-sensitive and multiplexed genomic and protein diagnostics in clinical laboratories, much as enzyme-linked immunosorbent assay, or ELISA, technology accelerated the use of protein testing in the 1970s and 1980s and the polymerase chain reaction, or PCR, catalyzed the emergence of nucleic acid diagnostics in the 1990s.
Our Gold Nanoparticle Molecular Probes
At the core of our technology is the use of gold nanoparticles which offer a unique set of physical properties that can be exploited in the detection of biological molecules. In 1998, Dr. Chad Mirkin, a former director of the Company, and Dr. Robert Letsinger at Northwestern University (“Northwestern”) developed a novel process to prepare stable probes by covalently attaching oligonucleotides to gold nanoparticles. This method, protected by patents, is exclusively assigned to or owned by us. We have refined the synthesis methods to enable highly reproducible production of nanoparticle probes with diameters in the 13-50 nanometer range required for highly sensitive biomedical analysis. Subsequently, we have also developed methods for attaching antibodies to gold nanoparticles, thereby producing highly stable probes for ultra-sensitive detection of proteins.
The properties of nanoparticle probes can be tailored by controlling the size of the particles, the density of recognition-oligomers or antibodies on the nanoparticles, the use of diluent oligonucleotides, the use of spacer oligonucleotides and the salt concentration. Combined, the optimization of these properties enables us to deliver superior analytical performance characteristics versus other methods, for example:

High Signal-to-Noise Ratio: Our nanoparticle probes deliver significantly stronger signals than the fluorescent probes, or fluorophores, used in most diagnostic platforms today. Nanoparticles are typically 10-100 nm in diameter and therefore significantly larger than conventional fluorophores. This size difference enables nanoparticles to produce up to 10,000

7


times more signal via light scattering than a fluorophore. A single nanoparticle can be detected with simple optical instrumentation with very high sensitivity, thus eliminating the need to employ amplification techniques.

Orders of Magnitude Greater Sensitivity and Lower Detection Limits. The sensitivity and limits of detection of our technology are further enhanced by a silver-staining step, which effectively amplifies the signal from each nanoparticle bound to a target molecule. In this process, silver is coated onto the gold nanoparticle surface, producing larger particles with further enhanced optical properties. Whereas the leading technologies today can detect molecules at the picomolar range (10-12 ), our technology is capable of up to a million times higher sensitivity at the attomolar (10-18 ) range, enabling the unprecedented analysis of rarely expressed genes or low abundance proteins for early disease detection and diagnosis.

Unparalleled Specificity: A key property of the oligonucleotide-linked gold nanoparticle is an extremely sharp melting curve. The melting curve is the temperature range during which the capture oligonucleotide dissociates with the complementary target oligonucleotide in the sample. Our nanoparticles exhibit dissociation transitions of less than one degree in Celsius temperature, whereas most alternative products are based on polymerase chain reaction, or PCR, which exhibits melt transitions typically in the 15-30 degree Celsius range. The narrow band of temperature in which binding and dissociation occurs, creates a significantly higher signal to noise ratio resulting in greater specificity. These qualities eliminate errors caused by mismatched nucleotide pairs, thereby allowing genomic targets differing by a single nucleotide (base pair) to be distinguished with unprecedented selectivity. Sharp melting curves are a proprietary feature of our nanoparticles and our patent portfolio includes issued patents protecting the methods and product performance related to melt transition curves.

High Count Multiplexing: Our core technology enables high count multiplexing, or simultaneous multiple target identification in a single sample using a simple low-density microarray. A sample and probe mixture is introduced simultaneously into a single self-contained reaction chamber pre-printed with multiple reaction spots, each containing capture strand oligonucleotides or proteins that are complementary to a specific target molecule of interest. By utilizing the sharp melt transition of the nanoparticle probes, multiple targets can be discretely identified in a single sample. This methodology eliminates the need for complex and costly means of physically isolating individual target molecules.

Detection of Genomic and Protein Molecules Simultaneously: We are able to synthesize our gold nanoparticle probes for the simultaneous multiplexed detection of both protein and genomic targets in the same assay.

Superior Reaction Kinetics: The sharp melt transition curves in our gold nanoparticles increase binding affinity thereby leading to improved assay kinetics and efficiency.

Long-Term Stability: The high density of oligonucleotides per nanoparticle, serves both as a protective and recognition layer on the nanoparticle surface and ensures the long-term stability of our nanoparticles. We have patented approaches using localized salt and buffer concentrations that deliver long-shelf life for our technology and reagent set.
Assay Format
Our gold nanoparticles probes and related optical detection technology are used in diagnostic assays which detect genomic and proteomic targets captured onto microarrays as shown in the “Schematic of Microarray Based Detection Using Nanoparticle Probes” below. The microarray format enables high count multiplexing of assay targets, facilitating the development of a broad menu of tests, including for complex diseases where multiple targets must be evaluated to provide a diagnosis, in a simple, scalable format.
Oligonucleotide probes are used for infectious disease and genomic assays. One probe, complementary to a specific site on the target molecule, is attached to a surface such as a glass slide and the other probe, complementary to a different site on the target molecule, is attached to the surface of gold nanoparticles. In the presence of the target molecule of interest, the probes and target form a three dimensional, cross-linked aggregate. After silver coating the gold nanoparticles, light scatter is measured on the surface of the microarray slide. The silver-enhanced gold nanoparticle probes located on the slide surface scatter light in proportion to the concentration of the target in the sample. This light is detected through optical imaging and translated into clinical results via our proprietary software algorithms. A similar detection strategy is used for protein detection assays with antibody‑based probes. Both probe types may be used in a single assay.

Intellectual Property
As of December 31, 2015, our patent portfolio is comprised, on a worldwide basis, of 192 issued patents and five pending patent applications which we own directly or for which we are the exclusive licensee. Some of these patents and patent applications derive from a common parent patent application or are foreign counterpart patent applications and relate to similar or identical technological claims. The issued patents cover approximately nine different technological claims and the pending patent applications cover approximately three additional technological claims.
Many of our issued and pending patents were exclusively licensed from the International Institute for Nanotechnology at Northwestern in May 2000, replaced and superseded in January 2006, and they generally cover our core technology, including nanotechnology-based biodiagnostics and biobarcode technology. Our issued patents expire between 2017 and 2025. We cannot assure that any of our licenses will continue in force for as long as we require for the development and commercialization of our products, and the early termination of these agreements could delay or prevent us from being able to commercialize our products. As our patent rights expire over time, we may not have commercially meaningful protection for our products or a commercial advantage against our competitors or their competitive products or processes. We believe our patent portfolio provides protection against other companies offering products employing the same technologies and methods as we have patented. While we believe our patent portfolio establishes a proprietary position, there are many competitive products utilizing other technologies that do not infringe on our patents.
In addition, as of December 31, 2015, we have non-exclusive licenses for at least 29 U.S. patents that cover eight different technological claims from various third parties. Most of these license agreements require us to pay the licensor royalty fees that typically expire upon the patent expiration dates, which range from 2016 to 2028. These license agreements are non-exclusive and do not create a proprietary position. The expiration of these non-exclusive licenses will result in the termination of certain royalty payments by us to the licensors.

Research and Development
Our research and development efforts are focused on:

Developing the next generation instrument platform: Our key focus is to develop the next generation platform based upon our well-understood existing instrument and chemistry. This platform, and associated assays also in development, has been designed to be highly competitive within the future market environment. Increased throughput, improved ease of use, and higher multiplexing with flexible reporting are all hallmarks of this next generation platform.

Expanding and Enhancing the Capabilities of Our Instrument Platform: Design elements and components of our current instrument platform will serve as the foundation for future generation development. Incremental improvements to our Verigene system and test menu will provide improved ease of use, expanded clinical utility, and test performance. It is anticipated that these developments will also provide for reduced costs and margin expansion.

Developing Additional Genomic and Protein Assays: We are in various phases of developing and commercializing new assays for detecting multiplexed nucleic acids, and combinations of nucleic acids and proteins, for infectious diseases.

Enhancing Performance of Established Product Systems and Developing New Applications: Our 2006 license agreement with Northwestern provided us with an exclusive license to certain existing patents and patent applications owned by Northwestern and future inventions developed by Northwestern that are related to (1) nanotechnology, which technology involves a particle where no single dimension is greater than 100 nanometers, and (2) biobarcode technology, which is analysis where oligonucleotides act as surrogate targets or reporter molecules. The license is limited to discoveries in the “Biodiagnostics Field” defined as qualitative or quantitative in vitro analysis, testing, measurement, or detection of various biodiagnostics field subjects and target combinations through January 1, 2013. Thereafter, the license provides that the Company continues to have the first right to an exclusive license for all discoveries the developed by Northwestern in the Biodiagnostics Field, however, the economic terms are to be negotiated in good faith by both parties. Our research team utilizes the research and patents developed at Northwestern to develop diagnostic applications including additional genomic and protein testing assays for use in the Verigene System.
Employees
As of December 31, 2015, we had 148 full-time employees. Of these employees, 41 were in research and development, 41 were in manufacturing (in support of both product sales and the research and development function), 41 were in sales and marketing and 25 were in general and administrative functions. We have never had a work stoppage and none of our employees are covered by collective bargaining agreements or represented by a labor union. We believe our employee relations are good.
Manufacturing
We assemble and package all our finished products at our corporate headquarters in Northbrook, Illinois. Our manufacturing facility occupies approximately 13,797 square feet of the 48,470 square feet, which we lease at our Northbrook facility. There, we manufacture our proprietary nanoparticle probes, assay reagents, test cartridges and instrumentation. We outsource much of the disposable component molding. Reagent manufacturing and cartridge filling is performed under the current Good Manufacturing Practices - Quality System Regulation as required by the FDA for the manufacture of in vitro diagnostic products. These regulations carefully control the manufacture, testing and release of diagnostics products as well as raw material receipt and control.
We have controlled methods for the consistent manufacturing of our proprietary nanoparticles and production oligonucleotides at very high purity (greater than 95%). We also manufacture at our Northbrook facility a proprietary linker to ensure stable bonding of the oligonucleotide to the gold nanoparticle.
All quality control tests are validated to ensure product quality measurements are accurate. Manufacturing of the Verigene System, including test cartridges, is tightly controlled with the use of manufacturing batch records. These records control which product is produced and ensure that each batch of product is manufactured consistently and according to the intended design.
We plan to continue to manufacture components that we determine are highly proprietary or difficult to produce consistently while outsourcing commodity components. As we continue to execute on our sales and marketing plans, we have ramped-up our manufacturing operations to meet demand. We are likely to establish additional outsourcing partnerships as we manufacture additional products. While we believe our current facilities and expansion rights are adequate to meet our manufacturing needs for at least the next two years, we may need to lease additional space.

Sales and Marketing
As a part of our business strategy, we have a direct sales and marketing organization to support the sales of the Verigene System and its initial menu of tests in the United States. This organization comprises geographically dispersed sales representatives and clinical support specialists as well as a centralized staff of market and product managers. We believe that the primary market for our diagnostic applications will be hospital-based laboratories and academic research institutions in the United States. A customer may purchase the Verigene System instruments, lease them from a third party or enter into a reagent rental agreement. Our reagent rental agreements include customer commitments to purchase a certain minimum volume of cartridges over the term of the agreement. As part of these agreements, a portion of the charge for each cartridge is a rental fee for use of the equipment.
Our sales and marketing organization provides customer service related to order fulfillment, technical service, training, product support and distribution logistics.
We believe that the primary international customers for our diagnostic applications will be hospital-based laboratories and academic research institutions. We have obtained CE IVD Mark certification for sale of the Verigene System in European Union countries and will do so for each assay we plan to market in Europe. Outside the United States, we initiate sales through marketing partners and distributors.
Competition
We primarily face competition in the nucleic acid based testing market from companies that provide PCR-based technologies. We believe that, over time, the Verigene System will compete with these companies primarily on the following factors: (1) clinical performance; (2) cost effectiveness; (3) ease of use; (4) multiplexing capability; (5) range of tests offered; (6) immediacy of results; and (7) reliability.
The Company is now focused primarily on molecular based infectious disease markets and therefore has identified bioMérieux (through its subsidiary BioFire Diagnostics), Becton Dickinson, GenMark Diagnostics, Cepheid, and Luminex as potential competitors.
We could also face competition in the protein detection market from companies that provide mass spectrometry systems. Although mass spectrometry systems offer high sensitivity, they are extremely costly, require significant time and effort by sophisticated staff and cannot detect many complex, disease-causing proteins. Due to these significant limitations we consider mass spectrometry systems to be a lower competitive threat within commercial protein diagnostics laboratories.
Regulation by the United States Food and Drug Administration
In the United States, the FDA regulates the sale and distribution, in interstate commerce, of medical devices, including in vitro diagnostic test kits. Pursuant to the federal Food, Drug, and Cosmetic Act, the FDA regulates the preclinical and clinical design and development, testing, manufacture, labeling, distribution and promotion of medical devices. We will not be able to commence marketing or commercial sales in the United States of new medical devices under development that fall within the FDA’s jurisdiction until we receive 510(k) clearance or approval from the FDA.
In the United States, medical devices are classified into one of three classes (i.e., Class I, II or III) on the basis of the controls deemed necessary by the FDA to reasonably ensure their safety and effectiveness. Class I devices are subject to general controls (e.g., establishment registration, medical device listing, labeling regulations, possible premarket notification and adherence to current Good Manufacturing Practice/Quality System Regulations (“QSR”)). However, most Class I devices are exempt from premarket notification (510(k) clearance). Class II devices are subject to general and special controls (e.g., special labeling requirements, mandatory performance standards, premarket notification (510(k) clearance) often with guidance from an FDA special control guideline, adherence to current Good Manufacturing Practice/QSR, possible post-market surveillance). Generally, Class III devices are subject to general and special controls and must receive premarket approval, or PMA, by the FDA to ensure their safety and effectiveness (e.g., new devices for which insufficient information exists to assure safety and effectiveness through general and special controls; often such devices are life-sustaining, life-supporting and implantable). Many devices that have been approved by way of premarket approval are required to perform post-market surveillance.
510(k) Clearance
The FDA will grant 510(k) clearance if the submitted information establishes that the proposed device is “substantially equivalent” to a legally marketed Class I or Class II medical device or a pre-amendment Class III medical device for which the FDA has not sought PMA. The FDA has recently been requiring more rigorous demonstration of substantial

11


equivalence than in the past. The FDA may determine that a proposed device is not substantially equivalent (“NSE”) to a legally marketed device or that additional information is needed before a substantial equivalence determination can be made. In the former case and when there exists no current legally marketed device to which substantial equivalence can be claimed, the De Novo Classification (Evaluation of Automatic Class III Designation) regulatory process may be utilized. Under this de Novo process, a device manufacturer can avoid having to seek PMA approval following an NSE determination, provided the device is considered by FDA to be a moderate to low risk device whose risks could be mitigated through the use of Special Controls. This enables the device to be “automatically” down-classified from Class III to Class II and marketing authorization sought essentially through the less burdensome 510(k) process. This process may be particularly applicable to many of our future products, in that they may utilize new or existing molecular markers and significantly different technology as compared to current marketed products or for which there is no existing like product on the market. Nonetheless, a “not substantially equivalent” determination, or a request for additional information, could prevent or delay the market introduction of new products that fall into this category. For any devices that are cleared through the 510(k) process, modifications or enhancements that could significantly affect safety or effectiveness, or constitute a major change in the intended use and/or performance of the device, require new 510(k) submissions and clearances.
Premarket Approval
A premarket approval ("PMA") application must be filed if a proposed device is a new device not substantially equivalent to a legally marketed Class I or Class II device, or if it is a pre-amendment Class III device for which the FDA has sought PMA. A PMA application must be supported by valid scientific evidence to demonstrate the safety and effectiveness of the device, typically including the results of clinical investigations, bench tests, and laboratory and animal studies. The PMA application must also contain a complete description of the device and its components and a detailed description of the method, facilities and controls used to manufacture the device. In addition, the submission must include the proposed labeling, advertising literature and any training materials. The PMA process can be expensive, uncertain and lengthy, and a number of devices for which FDA approval has been sought by other companies have never been approved for marketing.
Upon receipt of a PMA application, the FDA makes a threshold determination as to whether the application is sufficiently complete to permit a substantive review. If the FDA determines that the PMA application is complete, the FDA will accept the application for filing. Once the submission is accepted, the FDA begins an in-depth review of the PMA. The FDA’s review of a PMA application generally takes one to three years from the date the application is accepted, but may take significantly longer. The review time is often extended by the FDA asking for more information or clarification of information already provided in the submission. During the review period, an advisory committee, typically a panel of clinicians and subject matter experts, will likely be convened to review and evaluate the application and provide recommendations to the FDA as to whether the device should be approved. The FDA is not bound by the recommendation of the advisory panel, but often abides by it. Toward the end of the PMA review process, the FDA generally will conduct an inspection of the manufacturer’s facilities to ensure that the facilities are in compliance with applicable current Good Manufacturing Practices/QSR requirements.
If FDA evaluations of both the PMA application and the manufacturing facilities are favorable, the FDA may issue either an approval letter or an approvable letter, the latter of which contains a number of conditions 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, the Agency will issue an Approval Order, authorizing commercial marketing of the device for certain indications. If the FDA’s evaluation of the PMA application or manufacturing facilities is not favorable, the FDA will deny approval of the PMA application and issue a Not Approvable letter. The FDA may determine that additional clinical investigations are necessary, in which case the PMA may be delayed for one or more years while additional clinical investigations are conducted and submitted in an amendment to the PMA.
Modifications to a device that is the subject of an approved PMA, including its labeling or manufacturing process, most often require approval by the FDA of PMA supplements. Supplements to an approved PMA often require the submission of the same type of information required for an original PMA, except that the supplement is generally limited to that information needed to support the proposed change from the product covered by the original PMA. The FDA also has the authority to withdraw or temporarily suspend PMA approvals under specific circumstances.
Clinical Investigations
Before we can submit a medical device for 510(k) clearance, we may have to perform a relatively short (i.e., months) method comparison study at external clinical sites to ensure that the test performs appropriately when conducted by end users. This is a study in a clinical environment and is considered a clinical trial. However, patient-specific clinical outcome information is most often not required. Alternatively, when we submit a PMA, we generally must conduct a longer (i.e., years)

12


clinical trial of the device which supports the clinical utility of the device, demonstrating how the device will perform when used with patients in the test’s intended use population, establish the safety and effectiveness of the device.
Although clinical investigations of most devices are subject to the investigational device exemption ("IDE") requirements, clinical investigations of in vitro diagnostic tests, including our products and products under development, are exempt from approval of an IDE application prior to initiation of the clinical study, provided the testing is non-invasive, does not require an invasive sampling procedure that presents a significant risk, does not intentionally introduce energy into the subject, and is not used as a diagnostic procedure without confirmation by another medically established test or procedure. In addition, our tests must be labeled “for research use only” or “for investigational use only,” and distribution controls must be established to assure that our tests distributed for research, method comparisons, or clinical trials are used only for those purposes.
Regulation After FDA Approval or Clearance
Any devices we manufacture or distribute pursuant to 510(k) clearance or approval by the FDA are subject to pervasive and continuing regulation by the FDA and certain state agencies. We are required to adhere to applicable regulations setting forth detailed current Good Manufacturing Practices/QSR requirements, which include testing, control, design and documentation requirements. Non-compliance with these standards can result in, among other things, fines, injunctions, civil penalties, recalls or seizures of products, total or partial suspension of production, failure of the government to grant 510(k) clearance or PMA approval for devices, withdrawal of marketing approvals and criminal prosecutions. We have designed and implemented our manufacturing facilities under the current Good Manufacturing Practices/QSR requirements. Our manufacturing facility has been inspected by the FDA and will continue to be periodically inspected by the FDA.
On January 22, 2015, we received a warning letter (the “Warning Letter”) from the FDA resulting from inspections of our facility in Northbrook, Illinois by the FDA’s Chicago District Office that occurred in March 2014. The Warning Letter relates to deficiencies in our quality system regulation. On February 11, 2015, we submitted a response to the FDA addressing the deficiencies noted in the Warning Letter and the steps that we have taken, and continue to take, to remedy those deficiencies. These steps include, but are not limited to, a review and changes to our quality system procedures in the areas indicated in the Warning Letter, the hiring of new personnel and transfer of existing personnel to our quality assurance department, the completion of company-wide awareness training, and improvements to our record keeping policies and procedures. We believe that the full implementation of these measures, which remain subject to FDA review and confirmation via follow-up site inspection, will address the deficiencies noted by the FDA in the Warning Letter. We are committed to working with the FDA to regain full compliance with current Good Manufacturing Practices and QSR requirements.
Because we are a manufacturer of medical devices, we must also comply with medical device reporting ("MDR") requirements by reporting to the FDA any incident in which our product may have caused or contributed to a death or serious injury. We must also report any incident in which our product malfunctioned if that malfunction would likely cause or contribute to a death or serious injury if it were to recur. Labeling and promotional activities are subject to scrutiny by the FDA and, in certain circumstances, by the Federal Trade Commission. Current FDA enforcement policy prohibits the marketing of approved medical devices for unapproved uses.
We are also subject to numerous federal, state and local laws relating to such matters as safe working conditions, manufacturing practices, environmental protection, fire hazard control and disposal of hazardous or potentially hazardous substances. We have numerous policies and procedures in place to ensure compliance with these laws and to minimize the risk of occupational exposure to hazardous materials. In addition, we do not expect the operations of our products to produce significant quantities of hazardous or toxic waste that would require extraordinary disposal practices. Although the costs to comply with these applicable laws and regulations have not been material, we cannot predict the impact on our business of new or amended laws or regulations, or any changes in the way existing and future laws and regulations are interpreted or enforced. Moreover, as we develop toxin and pathogen detection products for the food and agriculture markets, we may be subject to the regulations of various food safety organizations, including the United States Department of Agriculture.
Export of Our Products
Export of products subject to the 510(k) notification requirements, but not yet cleared to market, are permitted with FDA authorization provided certain requirements are met. Unapproved products subject to the PMA requirements must be approved by the FDA for export. To obtain FDA export approval, we must meet certain requirements, including, with some exceptions, documentation demonstrating that the product is approved for import into the country to which it is to be imported and, in some instances, safety data for the devices.
Clinical Laboratory Improvement Amendments of 1988

13


The use of our products is also affected by the Clinical Laboratory Improvement Amendments of 1988 ("CLIA"), and related federal and state regulations, which provide for regulation of laboratory testing. These regulations mandate that clinical laboratories must be certified by the federal government, by a federally-approved accreditation agency or by a state that has been deemed exempt from the regulation’s requirements. Moreover, these laboratories must meet quality assurance, quality control and personnel standards, and they must undergo proficiency testing and inspections. The CLIA standards applicable to clinical laboratories are based on the complexity of the method of testing performed by the laboratory, which range from “waived” to “moderate complexity” to “high complexity.” Generally, the more complex the method of testing is, the higher the cost to perform the testing. We expect that most of our products will be categorized as either “moderate complexity” or “high complexity.” With the exception of 2C19 genetic test, which was classified as “high complexity”, all tests cleared by the FDA on the Processor SP have been categorized as “moderate complexity” by the FDA due to the ease in which to operate our Verigene system.
Foreign Government Regulation
We are marketing our products in certain foreign markets. Obtaining a CE IVD Mark is a mandatory requirement under the In-Vitro Diagnostic Directive 98/79/EC that addresses the essential requirements that an in-vitro diagnostic device must meet before being marketed within the European Union. We have obtained CE IVD Mark approval for sale of the Verigene System in European Union countries and will do so for any assay we plan to launch in Europe. Additional regulatory requirements exist in most foreign countries including, but not limited to, product standards, packaging requirements, labeling requirements and import restrictions on devices. Each country has its own tariff regulations, duties and tax requirements.

Item 1A. Risk Factors.
Our results from operations may be affected by the risk factors set forth below. All investors should consider the following risk factors before deciding to purchase securities of the Company. If any of the following events actually occur, our business, operating results, prospects or financial condition could be materially and adversely affected. This could cause the trading price of our common stock to decline and investors may lose all or part of their investment. The risks described below are not the only ones that we face. Additional risks not presently known to us or that we currently deem immaterial may also significantly impair our business operations and could result in a complete loss of your investment.
Risks Related to Our Business
We have a history of losses and we may never achieve or maintain profitability.
We have incurred significant losses in each fiscal year since our inception, including net losses of $30.6 million, and $39.1 million and in the years ended December 31, 2015, and 2014 respectively. As of December 31, 2015, we had an accumulated deficit of approximately $452.5 million. Our losses resulted principally from costs incurred in our research and development programs and from our general and administrative expenses. In recent years, we have incurred significant costs in connection with the development of the Verigene System and its test menu. We expect our research and development expense levels to remain high for the foreseeable future as we seek to enhance our existing product, and simultaneously develop new products. These losses, among other things, have had and will continue to have an adverse effect on our working capital, total assets and stockholders’ equity. Because of the numerous risks and uncertainties associated with our product development and

14


commercialization efforts, we are unable to predict when we will become profitable. The Company’s recurring losses from operations and continued use of cash to fund operations raise substantial doubt about our ability to continue as a going concern.
Our financial results depend on commercial acceptance of the Verigene System, its array of tests, and the development of additional tests.
Our future depends on the success of the Verigene System, which depends primarily on its acceptance by hospitals, research institutions, and independent diagnostic laboratories as a reliable, accurate and cost-effective replacement for traditional molecular diagnostic measurement methods. Many hospitals and laboratories already use expensive molecular diagnostic testing instruments in their laboratories and therefore, may be reluctant to change their current procedures for performing such analysis.
The Verigene System currently does not process a sufficiently broad menu of tests nor volume of samples for some hospitals and laboratories to consider adopting it. Although we continue to develop additional tests to respond to hospitals’ and laboratories’ needs, we cannot guarantee that we will be able to develop enough additional tests quickly enough, or in a manner that is cost-effective, or at all. The development of new or enhanced products is a complex and uncertain process, requiring the accurate anticipation of technological and market trends, as well as precise technological execution. We are currently not able to estimate when, or if we will be able to develop, commercialize or sell additional tests or enhance existing products. If we are unable to increase sales of the Verigene System and its tests, or to successfully develop and commercialize additional products or tests, our revenues and our ability to achieve profitability would be impaired.
The report of our independent registered public accounting firm on our 2015 financial statements contains an explanatory paragraph regarding our ability to continue as a going concern which may increase attention by current and future customers, vendors and future investors on our financial position. We will need additional financing to execute our business plan, to fund our operations and to continue as a going concern.
Since inception, we have experienced recurring operating losses and negative cash flows and we expect to continue to generate operating losses and consume significant cash resources for the foreseeable future. These conditions raise substantial doubt about our ability to continue as a going concern without additional financing. As a result, our independent registered public accounting firm included an explanatory paragraph in its report on our 2015 financial statements with respect to this uncertainty. Substantial doubt about our ability to continue as a going concern may materially and adversely affect the price per share of our common stock and we may have a more difficult time obtaining financing.
The explanatory paragraph in the report of our independent registered public accounting firm may increase awareness and concern of our financial position and impact our relationships with current and future customers, vendors and investors.
We have prepared our financial statements on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. Our 2015 financial statements do not include any adjustment to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the outcome of this uncertainty.
We will require additional capital to continue as a going concern.
We currently do not have sufficient capital to fully fund the activities needed to commercialize and market our full panel of assays for the Verigene Processor SP to generate net income. As of December 31, 2015, we had approximately $19.1 million of cash and cash equivalents, of which $4.0 million is restricted, and we anticipate having less than twelve months’ worth of sufficient cash on hand and cash from future operations to fund our operations. At our current cash utilization rate, as of December 31, 2015, we have approximately nine months of sufficient capital to fund our operations. The Company's current and anticipated cash resources will likely be insufficient to support currently forecasted operations within one year after the date that the financial statements are issued.
We do not anticipate achieving positive operating cash flow in at least the next twelve months. We require increased investment in additional manufacturing scale-up, and to add sales, marketing and customer support personnel during the next twelve months to advance the commercialization of our products. We operate in a market that makes our prospects difficult to evaluate, and achievement of positive cash flow from operations will depend upon revenue resulting from adoption of both our current products and future products that depend upon regulatory clearance. Demand for our respiratory products is directly proportional to the size and duration of the annual season for influenza and other respiratory illnesses. Any unanticipated acceleration or deceleration of customer demand for our product relative to projections will have a material effect on our cash flows.

15


Our current and anticipated cash resources will likely be insufficient to support currently forecasted operations beyond the next nine months, and we will need additional debt or equity financing in the future to execute our business plan and to be able to continue as a going concern. The Company received a deficiency notice from Nasdaq on January 25, 2016, regarding the Company’s failure to satisfy the minimum bid price as further described in footnote 14 to the financial statements. If in the future, we fail to satisfy the continued listing standards of NASDAQ, we may not be able to sell shares of our common stock. Market conditions, including the current historically very low price for our common stock, will likely limit our ability to raise capital on favorable terms, or at all, and the terms of any public or private offerings of debt or equity securities likely would be significantly dilutive to existing shareholders. Management also believes that, if necessary, it can implement plans in the short term to conserve existing cash should additional financing activities be delayed. Capital outlays and operating expenditures that would otherwise increase over the next twelve months as the Company expands its infrastructure, manufacturing capacity and research and development activities to support commercialization of our products may need to be curtailed, which may not be advantageous for the Company’s business operations.
We cannot guarantee that we would be able to obtain any of the additional debt or equity financing on commercially reasonable terms or at all, and we may continue to evaluate a full range of potential strategic alternatives. Additional equity funding could be dilutive to existing stockholders. If we fail to obtain the necessary debt or equity financing when needed, we may not be able to execute our planned development and commercialization efforts, which would have a material adverse effect on our growth strategy and our results of operations and financial condition. If we are unable to generate sufficient capital from operations or raise additional funds, we will need to do one or more of the following:
delay, scale-back, or eliminate research and development of some or all of assays or the next generation Verigene System;
license third parties to develop and commercialize products or technologies that we would otherwise seek to develop and commercialize ourselves;
accelerate our exploration of strategic alternatives, including attempting to sell our company which could then be on disadvantageous terms;
cease operations; or
file for bankruptcy.
The occurrence of any of the foregoing events would have a material adverse effect on our growth strategy and our results of operations and financial condition, and there can be no assurance that we would be able to continue as a going concern.
If we default on our loan agreement with NSPH Funding, LLC and SWK Funding, LLC, we may not be able to continue as a going concern.
Under the terms of our loan agreement with NSPH Funding, LLC, an affiliate of Life Sciences Alternative Funding LLC, and SWK Funding, LLC, a material adverse change in the Company’s financial condition could trigger an event of default. If an event of default occurs, all amounts owing under the loan agreement, currently approximately $20 million, would become immediately due and payable and the lenders could move against the collateral, including the seizure of our cash and cash equivalents that we maintain in restricted accounts. If an event of default were to occur, such actions by the collateral agent would have an immediate and substantial negative effect on our ability to continue as a going concern, as it would reduce our cash reserves to approximately $15.1 million as of December 31, 2015 which at our current cash utilization rate would provide working capital for approximately nine months from that date.
A significant amount of our inventory consists of instruments held by prospective customers who are evaluating our products and may not be converted to revenue on the timeframe that we anticipate or at all.
As of December 31, 2015, approximately $2.6 million of our inventory consisted of Verigene Processor SP instruments held by customers who are evaluating and testing our products. If a material number of these prospective customers do not adopt the Verigene System or the Processor SP within the time periods that we estimate or at all, then we will not be able to convert the inventory held by these customers to revenues. If we are unable to sell this inventory to other customers or if it becomes obsolete as we develop Atlas, our next generation Processor SP, we may be required to write off a significant portion of this inventory.

16


The regulatory approval process is expensive, time consuming and uncertain and the failure to obtain such approvals will prevent us from commercializing our future products.
Our products are subject to approval or clearance by the FDA or foreign governmental entities prior to their marketing for commercial use. The 510(k) clearance and premarket approval processes as well as the foreign approvals required to initiate sales outside the United States can be expensive, time consuming and uncertain. It may take as long as eighteen months or longer from submission to obtain 510(k) clearance, and from one to three years from submission to obtain premarket approval; however, it may take longer, and 510(k) clearance or premarket approval may never be obtained. Delays in receipt of, or failure to obtain, clearances or approvals for future products, including tests that are currently in development, would result in delayed, or no realization of revenues from such products, and in substantial additional costs, which could decrease our profitability. Relative to larger organizations, we have limited experience in filing FDA applications for 510(k) clearance and premarket approval. There are no assurances that we will obtain any required clearance or approval. Any such failure, or any material delay in obtaining the clearance or approval, could harm our business, financial condition and results of operations.
We and our customers are subject to various governmental regulations, and we may incur significant expenses to comply with, and experience delays in our product commercialization as a result of these regulations.
The products we develop, manufacture and market are subject to regulation by the FDA and numerous other federal, state and foreign governmental authorities. We generally are prohibited from marketing our products in the United States unless we obtain either 510(k) clearance or premarket approval from the FDA.
In addition, we are required to continue to comply with applicable FDA and other regulatory requirements once we have obtained 510(k) clearance or PMA approval for a product. These requirements include the Quality System Regulation, labeling requirements, the FDA’s general prohibition against promoting products for unapproved or “off-label” uses and adverse event reporting regulations. Failure to comply with applicable FDA product regulatory requirements could result in warning letters, fines, injunctions, civil penalties, repairs, replacements, refunds, recalls or seizures of products, total or partial suspension of production, the FDA’s refusal to grant future pre-market clearances or approvals, withdrawals or suspensions of current product applications and criminal prosecution. Any of these actions, in combination or alone, could prevent us from selling our products and would likely harm our business.
Our manufacturing facilities are subject to periodic regulatory inspections by the FDA and other federal and state regulatory agencies. The use of our diagnostic products by our customers is also affected by the Clinical Laboratory Improvement Amendments of 1988, or “CLIA”, and related federal and state regulations that provide for regulation of laboratory testing. CLIA is intended to ensure the quality and reliability of clinical laboratories in the United States by mandating specific standards in the areas of personnel qualifications, administration, participation in proficiency testing, patient test management, quality and inspections. Current or future CLIA requirements or the promulgation of additional regulations affecting laboratory testing may prevent some laboratories from using some or all of our diagnostic products. In January 2015, we received a warning letter from the FDA relating to deficiencies in our quality system regulation. Although we are committed to addressing the issues raised by the FDA, there can be no assurance that the FDA will be satisfied with the steps we have taken to address the issues or that the FDA will not raise additional areas of concern. We may be subject to additional regulatory action by the FDA, including product seizures, injunctions and/or civil money penalties and any such actions could have an adverse impact on our business, financial position and results of operations.
The FDA and foreign governmental regulators have made, and may continue to make, changes in approval requirements and processes. We cannot predict what these changes will be, how or when they will occur, or what effect they will have on the regulation of our products. Any new regulations, including regulations specifically related to nanotechnology, may impose additional costs or lengthen review times of our products. Delays in receipt of, or failure to receive regulatory approvals or clearances for our new products, would have a material adverse effect on our business, financial condition and results of operations.
If third-party payors do not reimburse our customers for the use of our clinical diagnostic products or if they reduce reimbursement levels, our ability to sell our products will be harmed.
We intend to sell our products primarily to hospital-based laboratories and academic research institutions, substantially all of which receive reimbursement for the health care services they provide to their patients from third-party payors, such as Medicare, Medicaid and other domestic and international government programs, private insurance plans and managed care programs. Most of these third-party payors may deny reimbursement if they determine that a medical product was not used in accordance with cost-effective treatment methods, as determined by the third-party payor, or was used for an unapproved indication. Third-party payors also may refuse to reimburse for procedures and devices deemed to be experimental.

17


In the United States, the American Medical Association assigns specific Current Procedural Terminology ("CPT") codes, which are necessary for reimbursement of diagnostic tests. Once the CPT code is established, the Centers for Medicare and Medicaid Services establish reimbursement payment levels and coverage rules under Medicaid and Medicare, and private payors establish rates and coverage rules independently. Although the tests performed by our assays in development have previously assigned CPT Codes, we cannot guarantee that our assays are covered by such CPT codes and are therefore approved for reimbursement by Medicare and Medicaid as well as most third-party payors. Additionally, certain of our future products may not be approved for reimbursement. Third-party payors may choose to reimburse our customers on a per test basis, rather than on the basis of the number of results given by the test. This may result in reference laboratories, public health institutions and hospitals electing to use separate tests to screen for each disease so that they can receive reimbursement for each test they conduct. In that event, these entities likely would purchase separate tests for each disease, rather than products that multiplex. Third-party payors are increasingly attempting to contain health care costs by limiting both coverage and the level of reimbursement for medical products and services. Increasingly, Medicare, Medicaid and other third-party payors are challenging the prices charged for medical services, including clinical diagnostic tests. Levels of reimbursement may decrease in the future, and future legislation, regulation or reimbursement policies of third-party payors may adversely affect the demand for and price levels of our products. If our customers are not reimbursed for our products, they may reduce or discontinue purchases of our products, which would cause our revenues to decline.
We may fail to receive positive clinical results from the diagnostic tests currently in development that require clinical trials, and even if we receive positive clinical results, we may still fail to receive the necessary clearances or approvals to market our products.
We are investing in the research and development of new products to expand the menu of testing options for the Verigene System. In order to commercialize our products, we are required to undertake time consuming and costly development activities, sometimes including clinical trials for which the outcome is uncertain. Products that appear promising during early development and preclinical studies may, nonetheless, fail to demonstrate the results needed to support regulatory approval. Even if we receive positive clinical results, we may still fail to obtain the necessary FDA 510(k) clearance and approvals.
Our operating results may be variable and unpredictable.
The sales cycles for our products may be lengthy, which will make it difficult for us to accurately forecast revenues in a given period, and may cause revenues and operating results to vary significantly from period to period. In addition to its length, the sales cycle associated with our products is subject to a number of significant risks, including the budgetary constraints of our customers, their inventory management practices and possibly internal acceptance reviews, all of which are beyond our control. Sales of our products will also involve the purchasing decisions of large, medium and small hospitals and laboratories which can require many levels of pre-approvals, further lengthening sales time. As a result, we may expend considerable resources on unsuccessful sales efforts or we may not be able to complete transactions on the anticipated schedule.
If we do not achieve our projected development goals in the quantities or time frames we estimate, the commercialization of our products may be delayed and our business prospects may suffer. The assumptions underlying our product placement and development goals also may prove to be materially inaccurate.
From time to time, we estimate the timing of the accomplishment of various scientific, clinical, regulatory and other product development goals. These goals may include the commencement or completion of scientific studies and clinical trials, the timing and number of product placements and the submission of regulatory filings. We also may disclose projected expenditures or other forecasts for future periods in information that we furnish to the SEC from time to time. These and other projections are based on management’s current expectations and may not contain sufficient margin of error, or cushion for any specific uncertainties, or for the uncertainties inherent in all forecasting. The actual timing of our product placement and development goals and actual expenditures or other financial results can vary dramatically compared to our estimates, in some cases for reasons beyond our control. If we do not meet projections as announced from time to time, the development, placement and commercialization of our products may be delayed and our business prospects may suffer. The assumptions management has used to produce these projections may significantly change or prove to be inaccurate. Accordingly, one should not unduly rely on any of these forward-looking statements.

18


If we do not achieve significant product revenue, we may not be able to meet our cash requirements without obtaining additional capital from external sources, and if we are unable to do so, we may have to curtail or cease operations.
We expect capital outlays and operating expenditures to increase over the next few years as we expand our infrastructure, commercialization, manufacturing, and research and development activities. Our current cash and cash equivalents are not sufficient to meet our estimated needs for the next twelve months. We operate in a market that makes our prospects difficult to evaluate, and we will need additional financing to execute on our current or future business strategies. The amount and the timing of the additional capital we will need to raise depend on many factors, including, but not limited to:
the level of research and development investment required to maintain and improve our technology;
the amount and growth rate, if any, of our revenues;
changes in product development plans needed to address any difficulties in manufacturing or commercializing the Verigene System and enhancements to our system;
the costs of filing, prosecuting, defending and enforcing patent claims and other intellectual property rights;
competing technological and market developments;
our need or decision to acquire or license complementary technologies or acquire complementary businesses;
the expansion of our sales force; and
changes in regulatory policies, practices or laws that affect our operations, including clearance to market our products.
We cannot be certain that additional capital will be available when and as needed, or that our actual cash requirements will not be greater than anticipated. If we require additional capital at a time when investment in diagnostics companies or in the marketplace in general is limited due to the then prevailing market or other conditions, we may not be able to raise such funds at the time that we desire, or any time thereafter. In addition, if we raise additional funds through the issuance of common stock or convertible securities, the percentage ownership of our stockholders could be significantly diluted, and these newly issued securities may have rights, preferences or privileges senior to those of existing stockholders. If we obtain additional debt financing, a substantial portion of our operating cash flow may be dedicated to the payment of principal and interest on such indebtedness, and the terms of the debt securities issued could impose significant restrictions on our operations. If we raise additional funds through collaborations and licensing arrangements, we might be required to relinquish significant rights to our technologies or products, or grant licenses on terms that are not favorable to us.
Our ability to use net operating losses and tax credits to offset future taxable income may be subject to certain limitations.
We currently have significant net operating losses ("NOLs") and tax credits that may be used to offset future taxable income. We have provided a valuation allowance for the full amount of our NOLs and tax credits. In general, under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “Code”), a corporation that undergoes an “ownership change” is subject to limitations on its ability to utilize its pre-change NOLs and tax credits to offset future taxable income. Our underwritten public offering of common stock or future changes in our stock ownership, some of which are outside of our control, could result, or likely has resulted, in an ownership change under Sections 382 and 383.
The adverse capital and credit market conditions could continue to affect our liquidity.
Adverse capital and credit market conditions could continue to affect our ability to meet liquidity needs, as well as our access to capital and cost of capital. The capital and credit markets have been experiencing volatility and disruption for more than 12 months. Our results of operations, financial condition, cash flows and capital position could be materially adversely affected by continued disruptions in the capital and credit markets.
If our products do not perform as expected or the reliability of the technology on which our products are based is questioned, we could experience lost revenue, delayed or reduced market acceptance of our products, increased costs and damage to our reputation.
Our success depends on the market’s confidence that we can provide reliable, high-quality diagnostics systems. We believe that customers in our target markets are likely to be particularly sensitive to product defects and errors.

19


Our reputation and the public image of our products or technologies may be impaired if our products fail to perform as expected or our products are perceived as difficult to use. Our products are complex and may develop or contain undetected defects or errors. Any defects or errors could lead to the filing of product liability claims, which could be costly and time-consuming to defend and result in substantial damages. If we experience a sustained material defect or error, this could result in loss or delay of revenues, delayed market acceptance, damaged reputation, diversion of development resources, legal claims, increased insurance costs or increased service and warranty costs, any of which could materially harm our business. We cannot assure that our product liability insurance would protect our assets from the financial impact of defending a product liability claim. A product liability claim could have a serious adverse effect on our business, financial condition and results of operations.
We rely on third-party license agreements for patents and other technology related to our products, and the termination of these agreements could delay or prevent us from being able to commercialize our products.
As of December 31, 2015, our patent portfolio is comprised, on a worldwide basis, of 192 issued patents and five pending patent applications which we own directly or for which we are the exclusive licensee. Some of these patents and patent applications derive from a common parent patent application or are foreign counterpart patent applications and relate to similar or identical technological claims. The issued patents cover approximately nine different technological claims and the pending patent applications cover approximately three additional technological claims.
Many of our issued and pending patents were exclusively licensed from the International Institute for Nanotechnology at Northwestern in May 2000, replaced and superseded in January 2006, and they generally cover our core technology, including nanotechnology-based biodiagnostics and biobarcode technology. Our issued patents expire between 2017 and 2025. We cannot assure that any of our licenses will continue in force for as long as we require for the development and commercialization of our products, and the early termination of these agreements could delay or prevent us from being able to commercialize our products. As our patent rights expire over time, we may not have commercially meaningful protection for our products or a commercial advantage against our competitors or their competitive products or processes. We believe our patent portfolio provides protection against other companies offering products employing the same technologies and methods as we have patented. While we believe our patent portfolio establishes a proprietary position, there are many competitive products utilizing other technologies that do not infringe on our patents.
In addition, as of December 31, 2015, we have non-exclusive licenses for at least 29 U.S. patents that cover eight different technological claims from various third parties. Most of these license agreements require us to pay the licensor royalty fees that typically expire upon the patent expiration dates, which range from 2016 to 2028. These license agreements are non-exclusive and do not create a proprietary position. The expiration of these non-exclusive licenses will result in the termination of certain royalty payments by us to the licensors.
If we are unable to obtain, maintain and enforce intellectual property protection covering our products, others may be able to make, use, or sell our products or substantially similar products, which could adversely affect our ability to compete in the market.
Our success is dependent in part on obtaining, maintaining and enforcing intellectual property rights, including patents. If we are unable to obtain, maintain and enforce intellectual property legal protection covering our products, others may be able to make, use or sell products that are substantially identical to ours without incurring the sizeable discovery, development and licensing costs that we have incurred, which would adversely affect our ability to compete in the market.
We seek to obtain and maintain patents and other intellectual property rights to restrict the ability of others to market products that compete with our products. However, patents may not be issued from any pending or future patent applications owned by or licensed to us, and moreover, issued patents owned or licensed to us now or in the future may be found by a court to be invalid or otherwise unenforceable. Also, even if our patents are determined by a court to be valid and enforceable, they may not be sufficiently broad to prevent others from marketing products similar to ours or designing around our patents, despite our patent rights, nor provide us with freedom to operate unimpeded by the patent rights of others.
Furthermore, we cannot be certain that we were the first to make the invention claimed in our United States issued patents or pending patent applications, or that we were the first to file for protection of the inventions claimed in our foreign issued patents or pending patent applications. In addition, there are numerous recent changes to the patent laws and proposed changes to the rules of the U.S. Patent and Trademark Office, which may have a significant impact on our ability to protect our technology and enforce our intellectual property rights. For example, in September 2011, the U.S. enacted sweeping changes to the U.S. patent system under the Leahy-Smith America Invents Act, including changes that would transition the U.S. from a “first-to-invent” system to a “first-to-file” system and alter the processes for challenging issued patents. These changes could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued

20


patents. We may become subject to interference proceedings conducted in the patent and trademark offices of various countries to determine our entitlement to patents, and these proceedings may conclude that other patents or patent applications have priority over our patents or patent applications. It is also possible that a competitor may successfully challenge our patents through various proceedings and those challenges may result in the elimination or narrowing of our patents, and therefore reduce our patent protection. Accordingly, rights under any of our issued patents, patent applications or future patents may not provide us with commercially meaningful protection for our products or afford us a commercial advantage against our competitors or their competitive products or processes.
We have a number of foreign patents and applications. However, the laws of some foreign jurisdictions do not protect intellectual property rights to the same extent as laws in the United States, and many companies have encountered significant difficulties in protecting and defending such rights in foreign jurisdictions. If we encounter such difficulties or we are otherwise precluded from effectively protecting our intellectual property rights in foreign jurisdictions, our business prospects could be substantially harmed.
We may initiate litigation to enforce our patent rights, which may prompt our adversaries in such litigation to challenge the validity, scope or enforceability of our patents. Patent litigation is complex and often difficult and expensive, and would consume the time of our management and other significant resources. In addition, the outcome of patent litigation is uncertain. If a court decides that our patents are not valid, not enforceable or of a limited scope, we may not have the right to stop others from using the subject matter covered by those patents. Patent law relating to the scope of claims in the technology fields in which we operate is still evolving and, consequently, patent positions in our industry are generally uncertain. We cannot assure you that we would prevail in any of these suits or that the damages or other remedies awarded, if any, would be commercially valuable. During the course of these suits, there may be public announcements of the results of hearings, motions and other interim proceedings or developments in the litigation. Any public announcements related to these suits could cause our stock price to decline.
We also rely on trade secret protection to protect our interests in proprietary know-how and for processes for which patents are difficult to obtain or enforce. We may not be able to protect our trade secrets adequately. In addition, we rely on non-disclosure and confidentiality agreements with our employees, consultants and other parties to protect, in part, our trade secrets and other proprietary technology. These agreements may be breached and we may not have adequate remedies for any breach. Moreover, others may independently develop equivalent proprietary information, and third parties may otherwise gain access to our trade secrets and proprietary knowledge. Any disclosure of confidential data into the public domain or to third parties could allow our competitors to learn our trade secrets and use the information in competition against us.
Our products could infringe patent rights of others, which may require costly litigation and, if we are not successful, could cause us to pay substantial damages or limit our ability to commercialize our products.
Our commercial success depends on our ability to operate without infringing the patents and other proprietary rights of third parties. We are aware of third party patents that may relate to our products and technology. There may also be other patents that relate to our products and technology of which we are not aware. We may unintentionally infringe upon valid patent rights of third parties. Although we are currently not involved in any material litigation involving patents, a third party patent holder could assert a claim of patent infringement against us in the future. Alternatively, we may initiate litigation against the third party patent holder to request that a court declare that we are not infringing the third party’s patent and/or that the third party’s patent is invalid or unenforceable. If a claim of infringement is asserted against us and is successful, and therefore we are found to infringe, we could be required to pay damages for infringement, including treble damages if it is determined that we knew or became aware of such a patent and we failed to exercise due care in determining whether or not we infringed the patent. If we have supplied infringing products to third parties or have licensed third parties to manufacture, use or market infringing products, we may be obligated to indemnify these third parties for damages they may be required to pay to the patent holder and for any losses they may sustain. We can also be prevented from selling or commercializing any of our products that use the infringing technology in the future, unless we obtain a license from such third party. A license may not be available from such third party on commercially reasonable terms, or may not be available at all. Any modification to include a non-infringing technology may not be possible or if possible may be difficult or time-consuming to develop, and require revalidation, which could delay our ability to commercialize our products.
Any infringement action asserted against us, even if we are ultimately successful in defending against such action, would likely delay the regulatory approval process of our products, harm our competitive position, be expensive and require the time and attention of our key management and technical personnel.
We have limited experience in sales and marketing and may be unable to successfully commercialize our Verigene System, or it may be difficult to build brand loyalty.

21


We have limited marketing, sales and distribution experience and capabilities. Our ability to achieve profitability depends on attracting customers for the Verigene System and building brand loyalty. To successfully perform sales, marketing, distribution and customer support functions ourselves, we will face a number of risks, including:
our ability to attract and retain the skilled support team, marketing staff and sales force necessary to commercialize and gain market acceptance for our technology and our products;
the ability of our sales and marketing team to identify and penetrate the potential customer base including hospitals, research institutions, and independent diagnostic laboratories;
the time and cost of establishing a support team, marketing staff and sales force; and
the difficulty of establishing brand recognition and loyalty for our products.
In addition, we may seek to enlist one or more third parties to assist with sales, distribution and customer support globally or in certain regions of the world. If we do seek to enter into such arrangements, we may not be successful in attracting desirable sales and distribution partners, or we may not be able to enter into such arrangements on favorable terms. If our sales and marketing efforts, or those of any third-party sales and distribution partners, are not successful, our technologies and products may not gain market acceptance, which would materially impact our business operations.
We may be unsuccessful in our long-term goal of expanding our product offerings outside the United States.
To the extent we begin to offer our products broadly outside the United States, we expect that we will be dependent on third-party distribution relationships. Distributors may not commit the necessary resources to market and sell our products to the level of our expectations. If distributors do not perform adequately, or we are unable to locate distributors in particular geographic areas, our ability to realize long-term international revenue growth would be materially adversely affected.
Additionally, our products may require regulatory clearances and approvals from jurisdictions outside the United States. These products may not be sold in these jurisdictions until the required clearances and approvals are obtained. We are not certain that we will be able to obtain these clearances or approvals on a timely basis, or at all.
Manufacturing risks and inefficiencies may adversely affect our ability to produce products.
We must manufacture or engage third parties to manufacture components of our products in sufficient quantities and on a timely basis, while maintaining product quality and acceptable manufacturing costs and complying with regulatory requirements. In determining the required quantities of our products and the manufacturing schedule, we must make significant judgments and estimates based on historical experience, inventory levels, current market trends and other related factors. Because of the inherent nature of estimates, there could be significant differences between our estimates and the actual amounts of products we require. Additionally, some of the components of the Verigene System are custom-made by only a few outside vendors, and we do not have long-term supply contracts for the materials or components supplied by any of our vendors. If we are unable to obtain from one or more of these vendors the needed materials or components that meet our specifications on commercially reasonable terms, or at all, we may not be able to meet the demand for our products. We have not arranged for alternate suppliers, and it may be difficult to find alternate suppliers in a timely manner and on terms acceptable to us.
We manufacture in one facility, and if there were to be a significant disruption in our ability to use this facility, it would take significant time to setup and validate an alternative manufacturing facility. Disruptions due to lack of power, flooding, fire and environmental controls could adversely impact our ability to manufacture. In addition, we have been steadily increasing manufacturing capacity to meet demand for our products. A disruption of our manufacturing operations resulting from scale-up related challenges such as obtaining sufficient raw materials, hiring of qualified factory personnel, installation and efficient operation of new equipment, and management of our quality controls could cause us to cease, delay, or limit our manufacturing operations and consequently adversely impact our business, our results of operations and our financial condition.
We may experience unforeseen technical complications in the processes we use to develop, manufacture, customize or receive orders for our products. These complications could materially delay or limit the use of products we attempt to commercialize, substantially increase the anticipated cost of our products or prevent us from implementing our processes at appropriate quality and scale levels, thereby causing our business to suffer. In addition, our manufacturing operations use highly technical processes involving unique, proprietary techniques that our manufacturing personnel must continuously monitor and update, especially as we develop more products. In order to be profitable, we must manufacture greater quantities of products than we have to date, and we must do this more efficiently than we have in the past. We may not be able to do so.

22


We will need to develop manufacturing capacity by ourselves, or with third parties.
We will need to either continue to build internal manufacturing capacity or contract with one or more manufacturing partners, or both. We currently use a combination of internal and outsourced manufacturing activities. We may encounter difficulties in manufacturing our products, and due to the complexity of our technology and our manufacturing process, we cannot be sure we fully understand all of the factors that affect our manufacturing processes or product performance. We may not be able to build manufacturing capacity internally or find one or more suitable manufacturing partners, or both, to meet the volume and quality requirements necessary to be successful in the market. If our products do not consistently meet our customers’ performance expectations, we may be unable to generate sufficient revenues to become profitable. Significant additional resources, implementation of additional manufacturing equipment and changes in our manufacturing processes and organization may be required for the scale-up of each new product prior to commercialization or to meet increasing customer demand once commercialization begins, and this work may not be successfully or efficiently completed. Any delay in establishing or inability to expand our manufacturing capacity could delay our ability to develop or sell our products, which would result in lost revenue and seriously harm our business, financial condition and results of operations.
Our business and future operating results may be adversely affected by events outside of our control.
We develop and manufacture the Verigene System instruments and assays in our facility located in Northbrook, Illinois. This facility and the manufacturing equipment we use would be costly to replace and could require substantial lead time to repair or replace. Our business and operating results may be harmed due to interruption of our manufacturing by events outside of our control, including earthquakes, tornadoes and fires. Other possible disruptions may include power loss and telecommunications failures. In the event of a disruption, we may lose customers and we may be unable to regain those customers thereafter. Our insurance 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 face intense competition from established and new companies in the molecular diagnostics field.
We compete with companies that design, manufacture and market already existing and new molecular diagnostics systems, and single target or low count multiplexing systems and assays are abundant. We anticipate that we will face increased competition in the future as new companies enter the market with new technologies and our competitors improve their current products. One or more of our competitors may offer technology superior to ours and render our technology obsolete or uneconomical. If a competitor were able to deliver a testing application that offers simplicity and ease of use, high count multiplexing and high throughput and fast turnaround, our ability to successfully market our products would be materially adversely affected. Most of our current competitors, as well as many of our potential competitors, have greater name recognition, more substantial intellectual property portfolios, longer operating histories, significantly greater resources to invest in new technologies and more substantial experience in new product development, regulatory expertise, manufacturing capabilities and the distribution channels to deliver products to customers. If we are not able to compete successfully, we may not generate sufficient revenue to become profitable.
Our success may depend upon how we and our competitors anticipate and adapt to market conditions.
The markets for our products are characterized by rapidly changing technology, evolving industry standards, changes in customer needs, emerging competition and new product introductions. The success of our products will depend on our ability to continue to increase their performance and decrease their price. New technologies, techniques or products could emerge with similar or better price-performance than our system and could exert pricing pressures on our products. It is critical to our success for us to anticipate changes in technology and customer requirements and to successfully introduce enhanced and competitive technology to meet our customers’ and prospective customers’ needs on a timely basis. We may not be able to maintain our technological advantages over emerging technologies in the future and we will need to respond to technological innovation in a rapidly changing industry. If we fail to keep pace with emerging technologies our system will become uncompetitive, our market share will decline and our business, revenue, financial condition and operating results could suffer materially.
We may not be able to manage our anticipated growth, and we may experience constraints or inefficiencies caused by unanticipated acceleration and deceleration of customer demand.
Demand for our respiratory products is directly proportionate to the size and duration of influenza and other respiratory illnesses. Unanticipated acceleration and deceleration of customer demand for our products may result in constraints or inefficiencies related to our manufacturing, sales force, implementation resources and administrative infrastructure. Such constraints or inefficiencies may adversely affect us as a result of delays, lost potential product sales or loss of current or potential customers due to their dissatisfaction. Similarly, over-expansion or investments in anticipation of growth that does not materialize, or develops more slowly than we expect, could harm our financial results and result in overcapacity.

23


To manage our anticipated future growth effectively, we must enhance our manufacturing capabilities and operations, information technology infrastructure, and financial and accounting systems and controls. Organizational growth and scale-up of operations could strain our existing managerial, operational, financial and other resources. Our growth could require significant capital expenditures and may divert financial resources from other projects, such as the development of new products or enhancements of existing products. If our management is unable to effectively manage our growth, our expenses may increase more than expected, our revenue could grow more slowly than expected and we may not be able to achieve our research and development and commercialization goals. Our failure to manage our anticipated growth effectively could have a material adverse effect on our business, operating results or financial condition.
We use hazardous chemicals, biological materials, and infectious diseases in our business. Any claims relating to improper handling, storage or disposal of these materials could be time consuming and costly.
Our research and development and manufacturing processes involve the controlled use of hazardous materials, including chemicals, biological materials and infectious diseases. Our operations produce hazardous waste products. We cannot eliminate the risk of accidental contamination or discharge and any resultant injury from these materials. We may be sued for any injury or contamination that results from our use or the use by third parties of these materials, and our liability may exceed our insurance coverage and our total assets. Federal, state and local laws and regulations govern the use, manufacture, storage, handling and disposal of these hazardous materials and specified waste products, as well as the discharge of pollutants into the environment and human health and safety matters. Compliance with environmental laws and regulations may be expensive, and may impair our research, development and production efforts. If we fail to comply with these requirements, we could incur substantial costs, including civil or criminal fines and penalties, clean-up costs, or capital expenditures for control equipment or operational changes necessary to achieve and maintain compliance. In addition, we cannot predict the impact on our business of new or amended environmental laws or regulations, or any changes in the way existing and future laws and regulations are interpreted and enforced.
If we are unable to recruit and retain key executives and scientists, we may be unable to achieve our goals.
Our performance is substantially dependent on the performance of our senior management and key scientific and technical personnel. The loss of the services of any member of our senior management or our scientific or technical staff could divert management’s attention to transition matters and identification of suitable replacements, if any, and have a material adverse effect on our business, operating results and financial condition. Each of our executive officers and other key employees could terminate his or her relationship with us at any time. We do not maintain key man life insurance on any of our employees.
In addition, our product development and marketing efforts could be delayed or curtailed if we are unable to attract, train and retain highly skilled employees and scientific advisors, particularly our management team, senior scientists and engineers and sales and marketing personnel. To expand our research, product development and sales efforts we need additional people skilled in areas such as protein science, information services, manufacturing, sales, marketing and technical support. Because of the complex and technical nature of our system and the dynamic market in which we compete, any failure to attract and retain a sufficient number of qualified employees could materially harm our ability to develop and commercialize our technology. We may not be successful in hiring or retaining qualified personnel and our failure to do so could have a material adverse effect on our business, financial condition and results of operations.
Healthcare reform and restrictions on reimbursement may adversely affect our profitability.
In the United States, healthcare providers that purchase our products and other diagnostic products generally rely on third-party payors to reimburse all or part of the cost of the procedure. In international markets, reimbursement and healthcare payment systems vary significantly by country, and include both government-sponsored healthcare and private insurance. Third-party payors can affect the pricing or the relative attractiveness of our products by regulating the maximum amount of reimbursement provided by such payors for laboratory testing services. Lower-than-expected or decreases in reimbursement amounts for tests performed using our products may decrease amounts physicians and other practitioners are able to charge patients, which in turn may adversely affect the willingness of physicians and other practitioners to purchase our products at prices we target, or at all. If we were not able to sell our products at target prices, then we will suffer a decrease in expected profitability that would likely adversely affect our business, financial condition and results of operations.
In addition, political, economic and regulatory influences are subjecting the healthcare industry to potential fundamental changes that could substantially affect our results of operations. Government and private sector initiatives to limit the growth of healthcare costs, including price regulation, competitive pricing, coverage and payment policies, comparative effectiveness of therapies, technology assessments and managed-care arrangements, are continuing. These changes are causing the marketplace to put increased emphasis on the delivery of more cost-effective treatments.

24


Security breaches and other disruptions could compromise our information and expose us to liability, which would cause our business and reputation to suffer.
In the ordinary course of our business, we collect and store sensitive data, including intellectual property, our proprietary business information and that of our customers and business partners, including personally identifiable information of our customers and employees, in our data centers and on our networks. Despite our security measures, our information technology and infrastructure may be vulnerable to attacks by hackers or breached due to employee error, malfeasance or other disruptions. Any such breach could compromise our networks and the information stored there could be accessed, publicly disclosed, lost or stolen. Any such access, disclosure or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information, disrupt our operations, and damage our reputation, which could adversely affect our business.
Risks Related to Our Common Stock
The market price of our common stock may be volatile and fluctuate significantly, which could result in substantial losses for investors and subject us to securities class action litigation.
Market prices of diagnostics companies have been volatile. Among the factors that may cause the market price of our common stock to fluctuate are the risks described in this “Risk Factors” section and other factors, including:
fluctuations in our quarterly operating results or the operating results of our competitors;
changes in estimates of our financial results or recommendations by securities analysts;
variance in our financial performance from the expectations of securities analysts;
fluctuations in the rate of quarterly product placements;
changes in the estimation of the future size and growth rate of our markets;
changes in accounting principles or changes in interpretations of existing principles, which could affect our financial results;
failure of our products to achieve or maintain market acceptance or commercial success;
conditions and trends in the markets we serve;
changes in general economic, industry and market conditions;
success of competitive products and services;
changes in market valuations or earnings of our competitors;
changes in our pricing policies or the pricing policies of our competitors;
announcements of significant new products, contracts, acquisitions or strategic alliances by us or our competitors;
changes in legislation or regulatory policies, practices, or actions;
the commencement or outcome of litigation involving our company, our general industry or both;
recruitment or departure of key personnel;
changes in our capital structure, such as future issuances of securities or the incurrence of additional debt;
actual or expected sales of our common stock by our stockholders; and
the trading volume of our common stock.
In addition, the stock market in general, the NASDAQ Capital Market, and the market for diagnostics companies in particular, may experience a loss of investor confidence. Such loss of investor confidence may result in extreme price and volume fluctuations in our common stock that are unrelated or disproportionate to the operating performance of our business, financial condition or results of operations. These broad market and industry factors may materially harm the market price of our common stock and expose us to securities class action litigation. Such litigation, even if unsuccessful, could be costly to defend and divert management’s attention and resources, which could further materially harm our financial condition and results of operations.
Our stock price has in the past and may in the future not meet the minimum bid price for continued listing on the Nasdaq

25


Capital Market. Our ability to publicly or privately sell equity securities and the liquidity of our common stock could be adversely affected if we are delisted from The NASDAQ Capital Market or if we are unable to transfer our listing to another national securities exchange or stock market.
On January 25, 2016, we received a deficiency letter from the Listing Qualifications Department of The NASDAQ Stock Market (the “Staff”), notifying us that, for the last 30 consecutive business days, the closing bid price of our common stock has not been maintained at the minimum required closing bid price of at least $1.00 per share as required for continued listing on The NASDAQ Capital Market pursuant to Listing Rule 5550(a)(2) (“Minimum Bid Price Rule”). In accordance with NASDAQ Listing Rules, we have been given 180 calendar days, or until July 25, 2016, to regain compliance with the Minimum Bid Price. If, at any time before July 25, 2016, the closing bid price of our common stock is at least $1.00 for a minimum of 10 consecutive business days, the Staff will provide written notification to us that we comply with the Minimum Bid Price Rule. During this 180 calendar day period, we also may submit a plan to regain compliance to NASDAQ and may request up to an additional 180 calendar days to complete the plan. There can be no assurance that we will regain compliance or maintain the listing of our common stock on the NASDAQ Capital Market or qualify to transfer the listing of our common stock to another national securities exchange or stock market. Delisting from NASDAQ would adversely affect our ability to raise additional financing through the public or private sale of equity securities, would significantly affect the ability of investors to trade our securities and would negatively affect the value and liquidity of our common stock. Delisting also could have other negative results, including the potential loss of confidence by employees, the loss of institutional investor interest and fewer business development opportunities.
The issuance of additional common stock may negatively impact the trading price of our common stock.
We have issued equity securities in the past and may continue to issue equity securities to finance our activities in the future. In addition, outstanding options and warrants to purchase our common stock may be exercised and additional options and warrants may be issued, resulting in the issuance of additional shares of common stock. The issuance by us of additional shares of common stock would result in dilution to our stockholders, and even the perception that such an issuance may occur could have a negative impact on the trading price of our common stock.
If equity research analysts do not publish research or reports about our business or if they issue unfavorable commentary or downgrade our common stock, the price of our common stock could decline.
The liquidity of the trading market for our common stock may be affected in part by the research and reports that equity research analysts publish about us and our business. We do not control the opinions of these analysts. The price of our stock could decline if one or more equity analysts downgrade our stock or if those analysts issue other unfavorable commentary or cease publishing reports about us or our business.
Certain provisions of our corporate governing documents could make an acquisition of our company more difficult.    
Certain provisions of our organizational documents could discourage potential acquisition proposals, delay or prevent a change in control of us or limit the price that investors may be willing to pay in the future for shares of our common stock. For example, our amended and restated certificate of incorporation and amended and restated by-laws:
authorize the issuance of preferred stock that can be created and issued by our board of directors without prior stockholder approval, commonly referred to as “blank check” preferred stock, with rights senior to those of our common stock;
limit the persons who can call special stockholder meetings;
provide that a majority vote of our stockholders is required to amend our amended and restated certificate of incorporation and amended and restated by-laws;
establish advance notice requirements to nominate persons for election to our board of directors or to propose matters that can be acted on by stockholders at stockholder meetings;
do not provide for cumulative voting in the election of directors; and
provide for the filling of vacancies on our board of directors by action of a majority of the directors and not by the stockholders.
These and other provisions in our organizational documents could allow our board of directors to affect the rights of a stockholder in a number of ways, including making it more difficult for stockholders to replace members of the board of directors. Because the board of directors is responsible for approving the appointment of members of the management team, these provisions could in turn affect any attempt to replace the current management team. These provisions could also limit the price that investors would be willing to pay in the future for shares of our common stock.

26


Our amended and restated articles of incorporation provide that Section 203 of the Delaware General Corporation Law, an anti-takeover law, will not apply to us. Section 203 generally prohibits an interested stockholder from engaging in certain types of business combinations with a Delaware corporation for three years after becoming an interested stockholder. An “interested stockholder” is a person who, together with affiliates and associates, owns 15% or more of the corporation.
We do not currently intend to pay dividends on our capital stock, and consequently, returns on investments will depend on the appreciation in price of our common stock.
We have never declared or paid any cash dividends on our common stock, and we currently intend to invest our future earnings, if any, to fund the development and growth of our business. Therefore, we do not anticipate declaring or paying cash dividends on our common stock in the foreseeable future. The payment of dividends will be at the discretion of our board of directors and will depend on our results of operations, capital requirements, financial condition, future prospects, contractual arrangements, restrictions imposed by applicable law, any limitations on payments of dividends present in our current and future debt agreements, and other factors our board of directors may deem relevant. If we do not pay dividends, and therefore, returns on investments in our company will depend on any future appreciation in the market price of our common stock. There is no guarantee that shares of our common stock will appreciate in value or even maintain the price at which our stockholders have purchased their shares.
We will continue to incur costs and demands upon management as a result of complying with the laws and regulations affecting public companies, which may adversely affect our operating results and failure to achieve and maintain effective internal controls in accordance with Section 404 of the Sarbanes-Oxley Act could cause investors to lose confidence in our operating results and in the accuracy of our financial reports and could have a material adverse effect on our business and on the price of our common stock.
As a public company, we are required, pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting for our 2015 fiscal year. Management is responsible for implementing controls and other procedures designed to ensure that information required to be disclosed by us in the reports that we file with the SEC is disclosed accurately and is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. While we have implemented the internal controls that we feel are necessary to comply with Section 404 of the Sarbanes Oxley Act, these controls may become inadequate because of changes in conditions, or the degree of compliance with these policies or procedures may deteriorate.
Furthermore, as a public company, changing laws, regulations and standards relating to corporate governance and public disclosure, including regulations implemented by the Securities and Exchange Commission and the NASDAQ may increase legal and financial compliance costs and make some activities more time consuming. These laws, regulations and standards are subject to varying interpretations, and as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. We intend to invest resources to comply with evolving laws, regulations and standards, and this investment may result in increased general and administrative expenses and a diversion of management’s time and attention from revenue-generating activities to compliance activities. If, notwithstanding our efforts to comply with new laws, regulations and standards, we fail to comply, regulatory authorities may initiate legal proceedings against us and our business may be harmed.
Failure to comply with these rules might also make it more difficult for us to obtain certain types of insurance, including director and officer liability insurance, and we might be forced to accept reduced policy limits and coverage and/or incur substantially higher costs to obtain the same or similar coverage. The impact of these events could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, on committees of our board of directors, or as executive officers.
Item 1B. Unresolved Staff Comments.

Item 2. Properties.
Our administrative, executive, research and development, and manufacturing functions are all located at a 48,470 square foot leased facility in Northbrook, Illinois. The lease for our Northbrook facility expires in May 2017. We do not own any real property.
Item 3. Legal Proceedings.

27


We are from time to time subject to various claims and legal actions during the ordinary course of our business. We believe that there are currently no claims or legal actions that would, in management’s judgment based on information currently available, have a material adverse effect on our results of operations, financial condition or cash flow.

Item 6. Selected Financial Data.
Not applicable.
Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
The following discussion and analysis is based primarily on the financial statements of Nanosphere, Inc. for the years presented and should be read together with the notes thereto contained in this annual report on Form 10-K. Terms employed herein as defined terms, but without definition, have the meanings set forth in the notes to the financial statements (see “Item 8. Financial Statements and Supplementary Data”).
Business Overview
We develop, manufacture and market an advanced molecular diagnostics platform, the Verigene® System, that enables simple, low cost and highly sensitive genomic and protein testing on a single platform. Our proprietary nanoparticle technology provides the ability to detect multiple targets simultaneously in a single sample. We are dedicated to enhancing medicine by providing targeted molecular diagnostic tests for infectious diseases and associated drug resistance markers that can lead to earlier disease detection, optimal patient treatment and improved healthcare economics. The Verigene System includes a bench-top molecular diagnostics workstation and single use consumable for on demand testing.
We believe the Verigene System is differentiated by its ease of use, superior analytical performance and ability to detect many targets on a single test, referred to as “multiplexing”. It provides lower cost solutions for laboratories not already performing molecular diagnostic testing and enables the full range of hospital laboratories and hospitals without advanced diagnostic capabilities to perform molecular genetics and infectious disease testing. Our unique ability to detect proteins, in addition to genetic and drug resistant markers, at sensitivity levels considerably higher than current methods for certain targets, may enhancing the viability and clinical utility of both new and existing biomarkers potentially allowing for earlier detection and intervention for various disease states.
Our test offering has the potential and has been shown to improve patient outcomes compared to current culture based microbiology methods by providing rapid and clinically actionable results that can reduce mortality, reduce the use of and costs associated with unnecessary antibiotics and associated drug resistance, and improve healthcare economics.
In addition to our menu of infectious disease tests, we are currently developing a next generation Verigene system that will deliver improved user experience. This system is designed to provide reduced time to result, improved user interface, including a single room temperature cartridge all in a fully automated sample to result system with an optimized footprint.
At this time, we believe our current Verigene System instrument inventory levels are sufficient to meet demand. With our next generation Verigene System in development, we will closely monitor inventory levels and forecasted sales to manage our investment to meet demand while managing the risk of obsolete inventory. A significant portion of our inventory is instruments held at outside customers for evaluation prior to purchase. These instruments may not convert to sales and may be returned to the Company. If returned, these instruments are refurbished and remain available for sale inventory. The cost basis of our inventory is reduced for any products that are considered excessive or obsolete based upon assumptions about future demands and market conditions. If actual future demands or market conditions are less favorable than those projected by management, inventory write-downs may be required.

Infectious Disease Assays
The conversion of traditional culture based methods of microbiology testing methods to more rapid molecular methods is driven by the need to identify infectious diseases more quickly, allowing a more rapid commencement of appropriate clinical intervention. Microbiology labs require tests that can rapidly detect a wide range of potential infectious agents in an automated system.
The Verigene System provides the multiplexing, rapid turnaround and ease-of-use needed by these labs. Our infectious disease menu and the Processor SP provide microbiology labs with the ability to identify infectious pathogens and antibiotic resistance in hours as compared to days using traditional methods.
We have received 510(k) clearance from the FDA for our respiratory panel that detects the presence of influenza A and B as well as respiratory syncytial virus (“RSV”) A and B. Influenza is commonly known as the seasonal flu and RSV is a respiratory virus that infects the lungs and breathing passages. RSV is the most common cause of bronchitis and pneumonia in children under the age of one year and has become a significant concern for older adults. Our respiratory panel provides physicians with a highly accurate and fast determination of which virus is present. This test result guides the most appropriate treatment therapy.
In the fourth quarter of 2009, we received 510(k) clearance from the FDA for our respiratory panel on the Processor SP. We believe that our respiratory assay on the Processor SP offers a simple-to-use molecular test for diagnosing respiratory infections and the flu, while providing improved sensitivity over currently available rapid tests. Additionally, we have received clearance for a package insert change for this assay confirming that the novel H1N1 virus is detected as a positive Influenza A when using our respiratory assay and the Processor SP.
In the first quarter of 2011, we received 510(k) clearance from the FDA and obtained CE IVD Mark for our respiratory assay (RV+) that includes subtyping for seasonal H1 virus, seasonal H3 virus, and the 2009 novel H1N1 virus, commonly known as swine flu, as well as the targets on our previously cleared respiratory assay.
The RV+ test has been further expanded to include additional viral and bacterial respiratory pathogens. This expanded panel, the the RP Flex assay ("RP Flex"), is designed to enable hospital-based laboratories to identify complex infections for a broader patient population. We obtained CE IVD Mark for the RP Flex in the second quarter of 2015 and received 510(k) clearance in the third quarter of 2015. The RP Flex contains a panel of 16 viral and bacterial targets and allows for the selection of any combination of targets for an individual sample. In addition, the RP Flex also provides pricing matched to the targets selected, therefore combining clinical utility with healthcare economics. This flexible panel addresses the varied respiratory testing needs of patients, labs and clinicians with a single comprehensive, yet cost-effective solution.

Nanosphere has developed and is continuing to develop bloodstream infection panels for the earlier detection of specific bacteria and resistance markers present in patients with bloodstream infections. These panels include gram-positive, gram-negative and yeast pathogens as well as resistance markers. These assays are designed to enable physicians to detect bacterial strains infecting patients and thus prescribe the most appropriate antibiotic regimen within 2.5 hours after positive blood culture and Gram stain identification rather than after several days, which is typical for current traditional culture assays. The sensitivity and specificity of bloodstream infection tests enable clinicians to make better therapeutic decisions sooner, thus improving patient outcomes and reducing costs. Multiple treatments are often initiated before these current traditional assays are complete. This early detection capability also allows patients to avoid unnecessary treatments that may expose them to serious side effects. The first bloodstream infection panel developed was for the detection of gram-positive organisms (BC-GP) that represent approximately 65% of bloodstream infections. In June 2012, we received a de novo 510(k) clearance, representing the first ever molecular bloodstream infection test to market the full BC-GP panel. In January 2014, we received 510(k) clearance for our gram-negative ("BC-GN") assay representing approximately 35% of bloodstream infections.
Diarrhea caused by bacterial and viral infection represents a significant healthcare burden in the U.S. Since symptoms alone are insufficient to make treatment decisions, rapid identification of the bacterial or viral cause of diarrhea is critical for optimal patient management, limiting the prescription of inappropriate or unnecessary antibiotics. Nanosphere has an active program in the development of diagnostic tests for gastrointestinal/enteric infections. We developed a molecular test to detect C. difficile, a bacterium that can cause symptoms ranging from diarrhea to life-threatening inflammation of the colon. For our C. difficile test, we received 510(k) clearance from the FDA in the fourth quarter of 2012 and obtained CE IVD Mark in the first quarter of 2013.
Nanosphere has also developed a multiplexed molecular enteric pathogens (EP) test which tests for a wide spectrum of bacteria and viruses causing gastrointestinal infections. This EP test is a cost-effective alternative to conventional identification methods that are time- and labor-intensive. We received 510(k) clearance from the FDA in October 2014 for our EP test and obtained CE IVD Mark in the second quarter of 2015. In addition, we have a next generation Enteric panel that incorporates our Flex capability that will allow for user selected targets of bacterial, viral and parasitic targets all in a Flex pricing format similar to our recently cleared respiratory Flex panel. We believe these Flex panels provide clinical and economic value to laboratories, clinicians and providers.
Human and Pharmacogenetic Assays
While our core focus is in the infectious disease applications, we also offer a limited menu of human and pharmacogenetic assays on our original Verigene processor and distribute into limited customer base in the U.S. and certain international markets.
We received 510(k) clearance from the FDA for a warfarin metabolism assay performed on our Original Verigene Processor. This is a pharmacogenetic test to determine the existence of certain genetic mutations that affect the metabolism of warfarin-based drugs, including Coumadin®, the most-prescribed oral anticoagulant. CE IVD Mark was obtained for this assay during the first quarter of 2011.
We also received 510(k) clearance from the FDA for a hypercoagulation assay performed on our Original Verigene Processor. This is a human genetic test to determine the existence of certain genetic mutations that are hereditary contributory factors in forming blood clots. This Verigene test detects the F5, F2, and MTHFR genes that are associated with hypercoagulation (i.e., thrombophilia). CE IVD Mark was obtained for this assay on the Processor SP during the fourth quarter of 2011.
In the fourth quarter of 2012 we received 510(k) clearance from the FDA for a CYP2C19 genetic variance test which we do not currently market in the U.S. This assay was CE IVD Marked during the first quarter of 2011 and is distributed in certain international markets. This test detects variances in the cytochrome P-450 2C19 gene. These genetic variances are associated with deficient metabolism of CYP2C19-metabolized therapeutic agents including clopidogrel, more commonly known by the trade name Plavix™.
Ultra-Sensitive and Multiplexed Protein Assays
We also have the capability to detect proteins at high sensitivity, either alone or in combination with nucleic acid targets. In the future, we may develop diagnostic tests for markers utilizing this ultra-sensitive capability that can be used to diagnose a variety of medical conditions including cardiovascular, respiratory, cancer, autoimmune, neurodegenerative and other diseases.

Intellectual Property
As of December 31, 2015, our patent portfolio is comprised, on a worldwide basis, of 192 issued patents and five pending patent applications which we own directly or for which we are the exclusive licensee. Some of these patents and patent applications derive from a common parent patent application or are foreign counterpart patent applications and relate to similar or identical technological claims. The issued patents cover approximately nine different technological claims and the pending patent applications cover approximately three additional technological claims.
Many of our issued and pending patents were exclusively licensed from the International Institute for Nanotechnology at Northwestern in May 2000, replaced and superseded in January 2006, and they generally cover our core technology, including nanotechnology-based biodiagnostics and biobarcode technology. Our issued patents expire between 2017 and 2025. We cannot assure that any of our licenses will continue in force for as long as we require for the development and commercialization of our products, and the early termination of these agreements could delay or prevent us from being able to commercialize our products. As our patent rights expire over time, we may not have commercially meaningful protection for our products or a commercial advantage against our competitors or their competitive products or processes. We believe our patent portfolio provides protection against other companies offering products employing the same technologies and methods as we have patented. While we believe our patent portfolio establishes a proprietary position, there are many competitive products utilizing other technologies that do not infringe on our patents.
In addition, as of December 31, 2015, we have non-exclusive licenses for at least 29 U.S. patents that cover eight different technological claims from various third parties. Most of these license agreements require us to pay the licensor royalty fees that typically expire upon the patent expiration dates, which range from 2016 to 2028. These license agreements are non-exclusive and do not create a proprietary position. The expiration of these non-exclusive licenses will result in the termination of certain royalty payments by us to the licensors.
Regulation by the United States Food and Drug Administration
In the United States, the FDA regulates the sale and distribution, in interstate commerce, of medical devices, including in vitro diagnostic test kits. Pursuant to the federal Food, Drug, and Cosmetic Act, the FDA regulates the preclinical and clinical design and development, testing, manufacture, labeling, distribution and promotion of medical devices. We will not be able to commence marketing or commercial sales in the United States of new medical devices under development that fall within the FDA’s jurisdiction until we receive 510(k) clearance or approval from the FDA.
All of the devices we manufacture or distribute pursuant to 510(k) clearance or approval by the FDA are subject to pervasive and continuing regulation by the FDA and certain state agencies. We are required to adhere to applicable regulations setting forth detailed current Good Manufacturing Practices/QSR requirements, which include testing, control, design and documentation requirements. Non-compliance with these standards can result in, among other things, fines, injunctions, civil penalties, recalls or seizures of products, total or partial suspension of production, failure of the government to grant 510(k) clearance or PMA approval for devices, withdrawal of marketing approvals and criminal prosecutions. We have designed and implemented our manufacturing facilities under the current Good Manufacturing Practices/QSR requirements. Our manufacturing facility has been inspected by the FDA and will continue to be periodically inspected by the FDA.
On January 22, 2015, we received a warning letter (the “Warning Letter”) from the FDA resulting from inspections of our facility in Northbrook, Illinois by the FDA’s Chicago District Office that occurred in March 2014. The Warning Letter relates to deficiencies in our quality system regulation. On February 11, 2015, we submitted a response to the FDA addressing the deficiencies noted in the Warning Letter and the steps that we have taken, and continue to take, to remedy those deficiencies. These steps include, but are not limited to, a review and changes to our quality system procedures in the areas indicated in the Warning Letter, the hiring of new personnel and transfer of existing personnel to our quality assurance department, the completion of company-wide awareness training, and improvements to our record keeping policies and procedures. We believe that the full implementation of these measures, which remain subject to FDA review and confirmation via follow-up site inspection, will address the deficiencies noted by the FDA in the Warning Letter. We are committed to working with the FDA to regain full compliance with current Good Manufacturing Practices and QSR requirements.

Financial Operations Overview
Revenue
Product sales revenue is derived from the sale or rental of the Verigene System, including test instruments and cartridges and related products sold to hospitals and commercial laboratories.

33


Cost of Sales
Cost of sales represents the direct cost incurred to manufacture and package products. Cost of sales includes labor costs for employees involved in the production process and the cost of raw materials and components used to produce the Verigene cartridges and instruments. Cost of sales also includes labor costs of employees supporting the production process, such as production management, quality, engineering, and other support services. Other costs in this category include depreciation of fixed assets, amortization of purchased intellectual property, royalties on product sales, utility costs, freight, operating lease expenses and other general manufacturing expenses.
Research and Development Expenses
Research and development expenses primarily include all costs incurred during the development of the Verigene System instruments and disposable test cartridges, and the expenses associated with developing manufacturing systems and processes. Such expenses include salaries and benefits for research and development personnel, consulting services, materials, patent-related costs and other expenses. We expense all research and development costs in the periods in which they are incurred. We expect research and development expenses to grow modestly as we continue to develop future generations of the Verigene System instruments, and additional genomic and protein tests.
Sales, General and Administrative Expenses
Sales, general and administrative expenses principally include compensation for employees in our sales, customer service, marketing, management and administrative functions. We also include professional services, facilities, technology, communications and administrative expenses in sales, general and administrative. The professional services costs primarily consist of legal and accounting costs. We expect sales and marketing expenses will increase as additional sales and customer support personnel are needed to drive and support customer growth.
Other Income
Interest income principally includes interest earned on our excess cash balances. Such balances are primarily invested in money market and bank checking accounts at major financial institutions. We expect that continued low interest rates will significantly limit our interest income in the near term.
Interest Expense
Interest expense includes the interest charges related to our debt borrowings, including non-cash amortization of debt discount and issuance costs.
Fiscal 2015 Compared to 2014
Revenues
Revenues in 2015 were $21.1 million as compared to $14.3 million in 2014, driven by a $6.3 million increase in consumable sales, and $0.5 million increase in instrument sales. The consumable increase was driven primarily by an increase in our infectious disease customer base and our expanded blood culture test menus. New customer placements for the fourth quarter 2015 were 34, totaling 109 for the full year ended December 31, 2015.
Cost of Sales & Gross Margin
Cost of sales in 2015 were $12.4 million, as compared to $8.5 million in 2014, an increase proportional to the increase in product sales revenues and expanded blood culture test menus. Gross margins for 2015 were 41.4% as compared to 40.5% in 2014.
Gross margin remained relatively flat due to the following: (1) an increase to our warranty and inventory reserves of $0.3 million due to recent experience, and (2) additional depreciation expense of $0.5 million related to an increase in leased evaluation equipment held at customer locations.
Net of these specific reserves, cost of goods sold was $11.5 million, a 35.3% increase when compared to 2014, due primarily to the increased cartridge sales during the year, and gross margin, net of these specific reserves, was at 45.4%, an increase of 490 basis points when compared to 2014, primarily due to operational efficiencies.

34


Research and Development Expenses
Research and development expenses in 2015 were $15.2 million, as compared to $21.7 million for 2014. This $6.5 million decrease in research and development expenses resulted primarily from the completion of clinical trials related to Enteric and RP Flex assays.
Sales, General and Administrative Expenses
Sales, general and administrative expenses decreased to $20.7 million in 2015, from $21.8 million in 2014, primarily due to a decrease in equity compensation expense related to the to the reduction in fair value of options granted in recent years compared to prior years.
Restructuring Expenses
Restructuring expenses of $0.5 million were recognized during the year 2015, in relation to severance costs associated with the reduction in workforce that occurred in January 2015, at which time the Company eliminated certain full time positions. All amounts were paid out during 2015. There were no restructuring costs in 2014.
Interest Expense
Interest expense was $2.9 million in 2015 as compared to $1.4 million in 2014. The increase was due to the new debt facility we entered into in May 2015.
Other Income
Other income was less than $0.1 million for each of 2015 and 2014.
Liquidity and Capital Resources
From our inception in December 1999 through December 31, 2015, we have received net proceeds of $141.8 million from the sale of convertible preferred stock and issuance of notes payable that were exchanged for convertible preferred stock, $102.2 million from our November 2007 initial public offering, $35.4 million from our October 2009 underwritten public offering, $32.2 million from our May 2011 underwritten public offering, $27.0 million from our July 2012 underwritten public offering of common stock, $4.7 million from our May 2013 underwritten public offering, $11.7 million from our May 2013 issuance of debt and warrants, $27.8 million from our September 2013 underwritten public offering of common stock, $18.5 million from our October 2014 underwritten public offering of common stock, $19.0 million from our May 2015 issuance of debt and warrants, $4.0 million from our May 2015 issuance of convertible preferred stock, $4.0 million from our June 2015 issuance of convertible preferred stock, and $9.2 million from our December 2015 issuance of preferred stock and common stock. We have devoted substantially all of these funds to research and development and sales, general and administrative expenses. Since our inception, we have generated minimal revenues from the sale of the Verigene System, including consumables and related products, to our initial clinical customers, research laboratories and government agencies. We also incurred significant losses and, as of December 31, 2015, we had an accumulated deficit of approximately $452.5 million. While we are currently in the commercialization stage of operations, we have not yet achieved profitability and anticipate that we will continue to incur net losses in the foreseeable future.
Market conditions, including an historically low price for our common stock, will likely limit our ability to raise additional capital on favorable terms, or at all, and the terms of any public or private offerings of debt or equity securities likely would be significantly dilutive to existing shareholders. Management also believes that, if necessary, it can implement plans in the short term to conserve existing cash should additional financing activities be delayed but that these efforts will not enable the Company to continue operations through at least the next twelve months. Capital outlays and operating expenditures that would otherwise increase over the next twelve months as the Company expands its infrastructure, manufacturing capacity and research and development activities to support commercialization of our products may need to be curtailed, which may not be advantageous for the Company's business operations.
There is no certainty that we would be able to obtain any of the additional debt or equity financing on commercially reasonable terms or at all, and we may continue to evaluate a full range of potential strategic alternatives. Additional equity funding could be dilutive to existing stockholders. If we fail to obtain the necessary debt or equity financing when needed, we may not be able to execute our planned development and commercialization efforts, which would have a material adverse effect on our growth strategy and our results of operations and financial condition. If we are unable to generate sufficient capital from operations or raise additional funds, we will need to do one or more of the following:
delay, scale-back or eliminate research and development of some or all of assays or the next generation Verigene System;

35


license third parties to develop and commercialize products or technologies that we would otherwise seek to develop and commercialize ourselves;
accelerate our exploration of strategic alternatives, including attempting to sell our company which could then be on disadvantageous terms;
cease operations; or
file for bankruptcy.
The occurrence of any of the foregoing events would have a material adverse effect on our growth strategy and our results of operations and financial condition, and there can be no assurance that we would be able to continue as a going concern.
A customer may purchase the Verigene System instruments, lease them from a third party or enter into a reagent rental agreement. Our reagent rental agreements include customer commitments to purchase a certain minimum volume of cartridges over the term of the agreement. As part of these agreements, a portion of the charge for each cartridge is a rental fee for use of the equipment. We may need to increase our investment in such systems rented to customers in order to support future customer growth.
As of December 31, 2015, we had $19.1 million in cash and cash equivalents of which $4.0 million is restricted, compared to $21.1 million at December 31, 2014. Cash used in operations of $25.6 million for the year ended December 31, 2015 was an improvement of $9.3 million as compared to $34.9 million in the year ended December 31, 2014, due to the increased revenues of $6.8 million, and decreased spending in research and development costs of $6.5 million due to the completion of clinical trial studies on Enteric and RP flex tests.
Net cash used in investing activities increased to $6.7 million for the year ended December 31, 2015, compared to $2.5 million for the year ended December 31, 2014, due primarily to the restricted cash of $4 million.
There was $26.3 million of new cash provided by financing activities for the year ended December 31, 2015. In May 2015, the Company received $20 million of a loan facility, and paid down its debt facility with SVB/ Oxford. The company further received a total of net proceeds of $17.2 million in its offering of its Series A, Series B, and Series C of preferred shares and Unit A common stock. There was $17.0 million of net cash provided by financing activities for the year ended December 31, 2014. In October 2014, the Company received $18.5 million in net proceeds from its underwritten public offering of common stock and $0.6 million in proceeds from the exercise of stock options. Also in 2014, the Company made $2.1 million in debt payments.
We may need to increase our capital outlays and operating expenditures over the next several years as we expand our product offering, drive product adoption, further scale-up manufacturing and implement product cost savings. The amount and the timing of the additional capital we will need to raise, if any, depend on many factors, including:
the level of research and development investment required to maintain and improve our technology;
the amount and growth rate of our revenues;
changes in product development plans needed to address any difficulties in manufacturing or commercializing the Verigene System and enhancements to our system;
the costs of filing, prosecuting, defending and enforcing patent claims and other intellectual property rights;
competing technological and market developments;
our need or decision to acquire or license complementary technologies or acquire complementary businesses; and
changes in regulatory policies or laws that affect our operations.
We cannot be certain that additional capital will be available when and as needed, or that our actual cash requirements will not be greater than anticipated. If we require additional capital at a time when investment in diagnostics companies or in the marketplace in general is limited due to the then prevailing market or other conditions, we may not be able to raise such funds at the time that we desire or any time thereafter. In addition, if we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our stockholders could be significantly diluted, and these newly-issued securities may have rights, preferences or privileges senior to those of existing stockholders. If we obtain additional debt financing, a substantial portion of our operating cash flow may be dedicated to the payment of principal and interest on such indebtedness, and the terms of the debt securities issued could impose significant restrictions on our operations. If we raise additional funds

36


through collaborations and licensing arrangements, we might be required to relinquish significant rights to our technologies or products, or grant licenses on terms that are not favorable to us.

Includes $1.0 million final payment which is being accreted through the end of the debt term.
License Agreements
We have entered into several nonexclusive license agreements with various companies covering certain technologies that are embedded in the Company’s diagnostic instruments and diagnostic test products. Since inception, we have paid aggregate initial license fees of $3.6 million for these licenses, and have agreed to pay a percentage of net sales as royalties, in percentage amounts ranging from less than 1% to 12%. Royalties on net sales are classified in cost of sales. Certain of these licenses expired, and the remaining licenses expire at various times, corresponding to the subject patents expirations, which currently range from 2016 to 2028.
Our 2006 license agreement with Northwestern provided us with an exclusive license to certain existing patents and patent applications owned by Northwestern and future inventions developed by Northwestern that are related to (1) nanotechnology, which technology involves a particle where no single dimension is greater than 100 nanometers, and (2) biobarcode technology, which is analysis where oligonucleotides act as surrogate targets or reporter molecules. The license is limited to discoveries in the “Biodiagnostics Field” defined as qualitative or quantitative in vitro analysis, testing, measurement, or detection of various biodiagnostics field subjects and target combinations through January 1, 2013. Thereafter, the license provides that the Company continues to have the first right to an exclusive license for all discoveries the developed by Northwestern in the Biodiagnostics Field, however, the economic terms are to be negotiated in good faith by both parties.. Our research team utilizes the research and patents developed at Northwestern to develop diagnostic applications including additional genomic and protein testing assays for use in the Verigene System.
Off-Balance Sheet Arrangements
We did not have any off-balance sheet financing or unconsolidated special-purpose entities as of December 31, 2015.
Critical Accounting Policies and Significant Judgments and Estimates
This discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in conformity with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as revenues and expenses during the reporting periods. We evaluate our estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other factors we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results could therefore differ materially from those estimates under different assumptions or conditions.

37


Our significant accounting policies are described in Note 2 to our financial statements included elsewhere in this Annual Report on Form 10-K. We believe the following critical accounting policies reflect our more significant estimates and assumptions used in the preparation of our financial statements.
Revenue Recognition
Verigene System instrument units are sold outright to customers, sold outright to leasing companies or rented by customers pursuant to operating leases. We recognize revenue from sales of the Verigene System, including cartridges and related products, when the risks and rewards of ownership are transferred to the customer. Revenue for Verigene System instrument units leased under operating lease arrangements is recognized on an installment basis over the life of the lease while the cost of the leased equipment is carried on the Company’s balance sheet and amortized over the life of lease arrangements.
Revenue for product sales is recognized when persuasive evidence of an arrangement exists, title and risk of loss is transferred to customers, the price to the buyer is fixed or determinable, and collectability is reasonably assured.
The Company’s sales contracts are considered multiple deliverable arrangements because the contract terms provide a fixed price for the sale of the Verigene System and a fixed price for the sale of cartridges over the term of the contract. Under these arrangements, the Company recognized revenue upon delivery of the products and allocates the revenue based on the relative selling price of each deliverable, which is based primarily on vendor specific objective evidence.
Inventories
Inventories are carried at the lower of cost or market, using the first-in, first out method. Certain finished goods inventory is ultimately leased by us rather than sold, and upon the lease date is transferred to Property and equipment and subsequently depreciated to Cost of sales over their useful life. Inventory was $6.1 million and $9.4 million as of December 31, 2015 and 2014, respectively. A significant portion of our inventory is instruments held at outside customers for evaluation prior to purchase.
The Company monitors inventory held at customer sites for evaluation (“Evaluation Equipment”). Upon determination that such Evaluation Equipment is no longer available for sale and is to remain with the customer, Evaluation Equipment is reclassified to property and equipment as leased equipment, which is typically after twelve months following initial placement. During 2015 the Company reclassified $3.3 million of Evaluation Equipment to property and equipment.  The Company commences depreciation on the date of transfer and such Evaluation Equipment is depreciated over a three year period.
Debt with Detachable Warrants
The Company accounts for debt with detachable warrants in accordance with ASC 470:  
Debt and allocated proceeds received to the debt and detachable warrants based on relative fair values. The Company assessed the classification of its common stock purchase warrants as of the date of the transaction and determined that such instruments meet the criteria for equity classification. The warrants are reported on the balance sheet as a component of additional paid in capital within stockholders’ equity.
The Company recorded the related issuance costs and value ascribed to the warrants as a reduction of the debt.  The discount is amortized utilizing the effective interest method over the term of the debt.  The unamortized discount, if any, upon repayment of the notes will be expensed to interest expense. The effective interest rate was determined in accordance with ASC Subtopic 470-20. The Company has also evaluated its debt and warrants in accordance with the provisions of ASC 815, Derivatives and Hedging, including consideration of embedded derivatives requiring bifurcation.
The Company evaluated its debt amendments under ASC 470 and determined that the amendments do not qualify as a troubled debt restructuring nor an extinguishment and therefore the effects of the amendments are reflected in future periods as an adjustment to interest expense.
Convertible Preferred Stock
The Company accounts for convertible preferred stock with detachable warrants in accordance with ASC 470:  
Debt and allocated proceeds received to the convertible preferred stock and detachable warrants based on relative fair values. The Company evaluated the classification of its convertible preferred stock and warrants and determined that such

38


instruments meet the criteria for equity classification. The Company recorded the related issuance costs and value ascribed to the warrants as a reduction of the convertible preferred stock.

The Company has also evaluated its convertible preferred stock and warrants in accordance with the provisions of ASC 815, Derivatives and Hedging, including consideration of embedded derivatives requiring bifurcation.
Beneficial conversion feature - The issuance of the convertible preferred stock generated a beneficial conversion feature (“BCF”), which arises when a debt or equity security is issued with an embedded conversion option that is beneficial to the investor or in the money at inception because the conversion option has an effective strike price that is less than the market price of the underlying stock at the commitment date. The Company recognized the BCF by allocating the intrinsic value of the conversion option, which is the number of shares of common stock available upon conversion multiplied by the difference between the effective conversion price per share and the fair value of common stock per share on the commitment date, to additional paid-in capital, resulting in a discount on the convertible preferred stock. As the convertible preferred stock may be converted immediately, we have recognized the BCF as a deemed dividend in the statement of operations.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Nanosphere, Inc.
Northbrook, Illinois

We have audited the accompanying balance sheets of Nanosphere, Inc. (the "Company") as of December 31, 2015 and 2014, and the related statements of operations and comprehensive loss, cash flows, and stockholders' equity, for each of the two years in the period ended December 31, 2015. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the financial statements based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
In our opinion, such financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2015 and 2014, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2015, in conformity with accounting principles generally accepted in the United States of America.
The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 3 to the financial statements, the Company's recurring losses from continued use of cash to fund operations raise substantial doubt about its ability to continue as a going concern. Management's plans concerning these matters are also discussed in Note 3 to the financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Nanosphere, Inc.
Notes to Financial Statements
As of December 31, 2015 and 2014, and
For the years ended December 31, 2015 and 2014
1. Description of Business
Nanosphere, Inc. (the “Company”) develops, manufactures and markets an advanced molecular diagnostics platform, the Verigene® System, that enables simple, low cost and highly sensitive genomic and protein testing on a single platform. The proprietary nanoparticle technology provides the ability to detect multiple targets simultaneously in a single sample. The Company is dedicated to enhancing medicine by providing targeted molecular diagnostic tests for infectious diseases and associated drug resistance markers that can lead to earlier disease detection, optimal patient treatment and improved healthcare economics. The Verigene System includes a bench-top molecular diagnostics workstation and single use consumable for on demand testing.
Basis of Presentation - The accompanying financial statements have been prepared on a going-concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business.
Reclassifications - Certain information as of December 31, 2014, presented in the financial statements have been reclassified to the current presentation. These reclassifications include: i) the reclassification of $0.1 million of debt issuance costs upon the early adoption of ASU No. 2015-03 to debt on the balance sheets, ii) the combination of warrants to acquire common stock within additional paid in capital on the balance sheets and statement of stockholders’ equity, and iii) the separate presentation of depreciation and amortization and accounts receivable and provision for doubtful accounts on the statements of cash flows, iv) the combination of foreign exchange gain/ loss and interest income on the income statement. These reclassifications had no impact on the results of operations, financial position, or cash flows.
2. Summary of Significant Accounting Policies
Cash and Cash Equivalents - The Company considers all highly liquid investments with a maturity of three months or less, at date of purchase, to be cash equivalents. The majority of these funds are held in interest-bearing money market and bank checking accounts. Interest income for all investment accounts is recorded on the accrual basis as earned.
Restricted Cash - Any cash that is legally restricted from use is recorded in restricted cash on the balance sheets. The new term loan facility (See Note 3) requires the Company to maintain a minimum account balance which is considered to be restricted cash. The restricted cash balance was $4.0 million on December 31, 2015, and there was no restricted cash on December 31, 2014.
Receivables - Accounts receivable consists of amounts due to the Company for sales of the Verigene system and consumables. We maintain an allowance for doubtful accounts to reflect the expected uncollectibility of accounts receivable based on past collection history and specific risks identified among uncollected accounts. This allowance was $0.2 million, and $0.1 million as of December 31, 2015, and 2014, respectively.
Inventories - Inventories are carried at the lower of cost or market, using the first-in, first-out method. Certain finished goods inventory is ultimately leased rather than sold, and upon the lease date is transferred to Property and equipment and subsequently depreciated to Cost of sales over the period indicated below.
Property and Equipment - Property and equipment are recorded at cost and generally depreciated using the straight-line method over the assets’ estimated useful lives, which are:
Equipment with customers
3-5 years
Computers and office equipment
3 years
Engineering and laboratory equipment, including tooling
3-5 years
Furniture and fixtures
7 years
Manufacturing equipment
5-7 years
Leasehold improvements
Shorter of useful life, or remaining lease term.

45


The economic life of the Company’s equipment with customers is based on the original term of the lease, which is typically three years. The Company believes that this is representative of the period during which the instrument is expected to be economically usable.
Maintenance and repair costs are expensed as incurred.
Depreciation Expense was $1.5 million, and $1.3 million for the years ended December 31, 2015, and 2014, respectively.
Intangible Assets - Intangible assets are stated at cost less accumulated amortization and consist of purchased intellectual property. Purchased intellectual property represents licenses and is associated with patents owned by third-parties for technologies which are embedded in the Company’s diagnostic instruments and diagnostic test products that the Company licensed in anticipation of sales of such products. Amortization of upfront license fees begins upon the initial use of the licensed technology and is calculated using the straight-line method over the remaining expected lives of the licensed technology, which range from 1.8 years to 11.25 years. Such amortization of upfront license fees is classified in Cost of sales on the statement of operations. Purchased intellectual property also includes purchased patents and patent rights. These patents and patent rights are amortized using a straight-line method over the remaining four years of the patent, and the amortization expense is classified in research and development expense on the statement of operations.
Impairment of Long-lived Assets - The Company monitors the carrying value of long-lived assets for potential impairment and tests the recoverability of such assets whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. If a change in circumstance occurs, the Company performs a test of recoverability by comparing the carrying value of the asset or asset group to its undiscounted expected future cash flows. If cash flows cannot be separately and independently identified for a single asset, the Company will determine whether impairment has occurred for the group of assets for which the Company can identify the projected cash flows. If the carrying values are in excess of undiscounted expected future cash flows, the Company measures any impairment by comparing the fair value of the asset or asset group to its carrying value.
Deferred Financing Costs - Costs incurred to issue debt are deferred and amortized as a component of interest expense using the effective interest method over the term of the related debt agreement. Amortization expense of deferred financing costs began with the incurrence of the debt in May 2013 and was $0.5 million and $0.1 million for the twelve months ended December 31, 2015 and December 31, 2014.
Use of Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the notes thereto. The Company’s significant estimates included in the preparation of the financial statements are related to property and equipment, intangible assets and share-based compensation. Actual results could differ from those estimates.
Fair Value of Financial Instruments - The carrying amount of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, and accounts payable approximate their fair values. Fair value of debt was $14.7 million and $9.8 million at December 31, 2015, and December 31, 2014, respectively. The fair value of debt is based upon the current rates available to us for debt with similar terms and remaining maturities (Level 2 financial measurement).
Reverse Stock Split - On April 7, 2015, the Company's Board of Directors and shareholders approved a 20-to-1 reverse split of the Company's issued and outstanding common stock, effective at the close of business on April 8, 2015. The effect of this event has been reflected in all the share quantities and per share amounts in these financial statements. The shares of common stock authorized remained at 150 million and retained a par value of $0.01.
Debt, with Detachable Warrants -  The Company accounts for debt with detachable warrants in accordance with ASC 470:  Debt and allocated proceeds received to the debt and detachable warrants based on relative fair values. The Company assessed the classification of its common stock purchase warrants as of the date of the transaction and determined that such instruments meet the criteria for equity classification. The warrants are reported on the balance sheet as a component of additional paid in capital within stockholders’ equity.
The Company recorded the related issuance costs and value ascribed to the warrants as a reduction of the debt.  The discount is amortized utilizing the effective interest method over the term of the debt.  The unamortized discount, if any, upon repayment of the notes will be expensed to interest expense. In accordance with ASC Subtopic 470-20, the Company determined the effective interest rate of the debt was approximately 22.0%. The Company has also evaluated its debt and warrants

46


in accordance with the provisions of ASC 815, Derivatives and Hedging, including consideration of embedded derivatives requiring bifurcation.

Convertible Preferred Stock -  The Company accounts for convertible preferred stock with detachable warrants in accordance with ASC 470:  Debt and allocated proceeds received to the convertible preferred stock and detachable warrants based on relative fair values. The Company evaluated the classification of its convertible preferred stock and warrants and determined that such instruments meet the criteria for equity classification. The Company recorded the related issuance costs and value ascribed to the warrants as a reduction of the convertible preferred stock.

The Company has also evaluated its convertible preferred stock and warrants in accordance with the provisions of ASC 815, Derivatives and Hedging, including consideration of embedded derivatives requiring bifurcation.
Beneficial conversion feature - The issuance of the convertible preferred stock generated a beneficial conversion feature (“BCF”), which arises when a debt or equity security is issued with an embedded conversion option that is beneficial to the investor or in the money at inception because the conversion option has an effective strike price that is less than the market price of the underlying stock at the commitment date. The Company recognized the BCF by allocating the intrinsic value of the conversion option, which is the number of shares of common stock available upon conversion multiplied by the difference between the effective conversion price per share and the fair value of common stock per share on the commitment date, to additional paid-in capital, resulting in a discount on the convertible preferred stock. As the convertible preferred stock may be converted immediately, we have recognized the BCF as a deemed dividend in the statement of operations.
Evaluation Equipment - The Company monitors inventory held at customer sites for evaluation (“Evaluation Equipment”). Upon determination that such Evaluation Equipment is no longer available for sale and is to remain with the customer, Evaluation Equipment is reclassified to property and equipment as leased equipment, which is typically after twelve months following initial placement. During 2015, the Company reclassified $3.3 million of Evaluation Equipment to property, plant, and equipment.  The Company commences depreciation on the date of transfer and such Evaluation Equipment is depreciated over a three year period.
Comprehensive Loss - The Company’s comprehensive loss is equal to its net loss for all periods presented.
Revenue Recognition - The Company recognizes revenue from product sales and contract arrangements. The Company recognizes revenue from product sales when there is persuasive evidence that an arrangement exists, delivery has occurred, the price is fixed or determinable and collectability is reasonably assured. Verigene System instrument units are sold outright to customers or leased to customers pursuant to operating leases. The Company recognizes revenue from sales of the Verigene System, including cartridges and related products, when the risks and rewards of ownership are transferred to the customer. The Company evaluates the financial position and payment history for each international distribution partner and recognizes revenue from these distributors only when timely collectability can be reasonably assured. Revenue for Verigene System instrument units sold under operating lease arrangements is recognized on an installment basis over the life of the lease while the cost of the leased equipment is carried on the Company’s balance sheet in Property and equipment and depreciated over its estimated useful life to Cost of sales.
Shipping and handling costs are expensed as incurred and included in Cost of sales. In those cases where the Company bills shipping and handling costs to customers, the amounts billed are classified as product sales.
The Company’s sales contracts are considered multiple deliverable arrangements because the contract terms provide a fixed price for the sale of the Verigene System and a fixed price for the sale of cartridges over the term of the contract. Under these arrangements, the Company recognized revenue upon delivery of the products and allocates the revenue based on the relative selling price of each deliverable, which is based primarily on vendor specific objective evidence.
Research and Development Costs - Research and development costs, including costs related to the clinical studies programs, consist of employee wages and benefits, development materials and equipment and facility costs and are expensed as incurred.
Income Taxes - The Company accounts for income taxes, including uncertain tax positions, under the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 740 “Accounting for Income Taxes”. This Topic requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates

47


in effect for the year in which the differences are expected to reverse. An allowance is provided to reduce net deferred tax assets to the amount management believes will, more likely than not, be recovered.
Share-Based Compensation - The Company recognizes share-based compensation expense related to restricted stock and common stock options issued to employees, consultants and directors. ASC Topic 718 “Stock Compensation” provides for recognition of compensation expense based on the fair value of the stock-based compensation utilizing various assumptions regarding the underlying attributes of the options and stock. The estimated fair value of options granted, net of forfeitures expected to occur during the vesting period, is amortized as compensation expense on a straight-line basis over the service period of the options.
Segments - Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker (“CODM”) in making decisions regarding resource allocation and assessing performance The Company’s chief executive officer is the CODM, and he uses the financial information in determining how to allocate resources and assess performance. The Company has determined that it operates in one segment. All of the Company’s assets are located in the United States and substantially all of the Company’s revenues are from customers in the United States.
        
Adoption of Recent Accounting Pronouncements: In August 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-15, Interest - Imputation of Interest: Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements, which clarifies the treatment of debt issuance costs from line-of-credit arrangements after the adoption of ASU No. 2015-03, Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs. In particular, ASU No. 2015-15 clarifies that the SEC staff would not object to an entity deferring and presenting debt issuance costs related to a line-of-credit arrangement as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of such arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The Company adopted ASU No. 2015-15 during the 2nd quarter of 2015, and its adoption did not have a material impact on its financial statements.

Recent Accounting Pronouncements: In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, an updated standard on revenue recognition.  ASU No. 2014-09 provides enhancements to the quality and consistency of how revenue is reported by companies while also improving comparability in the financial statements of companies reporting using International Financial Reporting Standards or U.S. GAAP.  The main purpose of the new standard is for companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which a company expects to be entitled in exchange for those goods or services. The new standard also will result in enhanced disclosures about revenue, provide guidance for transactions that were not previously addressed comprehensively and improve guidance for multiple-element arrangements.  In July 2015, the FASB voted to approve a one-year deferral of the effective date of ASU No. 2014-09, which will be effective for the Company in the first quarter of fiscal year 2018 and may be applied on a full retrospective or modified retrospective approach. The Company is evaluating the impact of implementation and transition approach of this standard on its financial statements.

In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory. This ASU changes the inventory valuation method from the lower of cost or market to the lower of cost or net realizable value for inventory valued under the first-in, first-out or average cost methods. The standard is effective for fiscal years beginning after December 15, 2016, including interim periods and requires prospective adoption with early adoption permitted. The Company is currently evaluating the impact of this guidance on its financial statements.

In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This ASU explicitly requires management to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosures in certain circumstances. In connection with each annual and interim period, management will assess if there is substantial doubt about an entity’s ability to continue as a going concern within one year after the issuance date. Management will consider relevant conditions that are known, and reasonably knowable, at the issuance date. Substantial doubt exists if it is probable that the entity will be unable to meet its obligations within one year after the issuance date. Disclosures will be required if conditions give rise to substantial doubt. The new standard will be effective for all entities in the first annual period ending after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact of this guidance on its financial statements.

In November 2015, the FASB issued Accounting Standards Update (“ASU”) 2015-17, “Balance Sheet Classification of Deferred Taxes,” which requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position to simplify the presentation of deferred income taxes. The standard is effective prospectively for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. As

48


of December 31, 2015, we elected to early adopt the pronouncement on a prospective basis. Adoption of this amendment did not have an effect on the Company's financial position or results of operations, and prior periods were not retrospectively adjusted.

In January 2016, FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. ASU No. 2016-01 requires equity investments to be measured at fair value with changes in fair value recognized in net income; simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; requires separate presentation of financial assets and financial liabilities by measurement category and form of financial assets on the balance sheet or the accompanying notes to the financial statements and clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. ASU No. 2016-01 is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company is currently evaluating the impact that ASU No. 2016-01 will have on its financial statements and related disclosures.        
3. Liquidity and Capital Resources
As of December 31, 2015, the Company has incurred net losses attributable to common shareholders of $452.5 million since inception, and has funded those losses primarily through the sale and issuance of equity securities and secondarily through the issuance of debt. While the Company is currently in the commercialization stage of operations, the Company has not yet achieved profitability and anticipates that it will continue to incur net losses in the foreseeable future. The Company recorded a net loss of $30.6 million in 2015 and had cash and cash equivalents of $15.1 million as of December 31, 2015, and net cash used in operating activities of $25.6 million for the twelve month period ended December 31, 2015.
The Company's current and anticipated cash resources will likely be insufficient to support currently forecasted operations within one year after the date that the financial statements are issued, and therefore, the Company will need additional debt or equity financing in the future to execute its business plan and to be able to continue as a going concern. Capital outlays and operating expenditures that would otherwise increase over the next twelve months as the Company expands its infrastructure, manufacturing capacity and research and development activities to support commercialization of our products may need to be curtailed which may not be advantageous for the Company's business operations. Many of the aspects of the Company’s forecasts involve management’s judgments and estimates that include factors that could be beyond the Company's control and actual results could differ. These and other factors could cause the Company's forecasted plans to be unsuccessful which could have a material adverse effect on the Company's operating results, financial condition, and liquidity and causes substantial doubt about the Company’s ability to continue as a going concern.
Term Loan Facility with NSPH Funding LLC and SWK Funding LLC
On May 14, 2015, (the "Closing Date") the Company entered into a Loan and Security Agreement ("Loan Agreement") with NSPH Funding LLC, an affiliate of Life Sciences Alternative Funding, LLC, and SWK Funding LLC, as lenders (together, the “Lenders”) providing for the Lenders to advance term loans in an aggregate amount of up to $30 million (the “Loan”) to the Company. NSPH Funding LLC also agreed to act as agent under the loan facility (the “Collateral Agent”).
The Company immediately drew down $20 million of the Loan. The Loan Agreement included a condition precedent and a post-closing covenant that obligated the Company to raise (i) an aggregate of at least $4 million in net proceeds from equity financings prior to entering into the Loan Agreement and (ii) an aggregate of at least $6 million in net proceeds from either equity financings or licensing or strategic partnership transactions within eight months following the Closing Date (collectively, the “Capital Requirements”), pursuant to which the Company raised an aggregate of $8 million in net proceeds from its preferred stock offerings in May 2015 and June 2015.
As consideration for the funding of the Loan and the Lenders’ commitment thereunder, on the Closing Date the Company issued warrants to the Lenders to acquire an aggregate of up to 1,000,000 shares of common stock, par value $0.01 (the “Common Stock”) with an exercise price of $0.01 per share and are exercisable for a period of 10 years until May 14, 2025 (the “Initial Lender Warrants”). At the time of issuance, the relative fair value of the Initial Lender Warrants was estimated at $3.9 million using the Black-Scholes model and recorded as a debt discount.
On July 29, 2015, the Company and the Lenders entered into the First Amendment to the Loan and Security Agreement (the “First Amendment”). The First Amendment reduced the Capital Requirements under the Loan Agreement by $2 million and included the Lenders’ acknowledgment that the Capital Requirements have been fully satisfied.

49


In consideration of the reduction of the Capital Requirements, the First Amendment also provides that the minimum account balance in the Company’s accounts that are subject to a control agreement in favor of the Collateral Agent, which was previously $3 million and subject to increase to $4 million after the earlier of the funding of the second tranche of the Loan or March 31, 2016, is increased to $4 million concurrent with the entry into the First Amendment by the Company and the Lenders and shall increase to $5 million after the earlier of the funding of the second tranche of the Loan or December 31, 2016.
In addition, the Loan Agreement provides that the Company maintain minimum quarterly ratios of (i) the aggregate of the Company’s cash operating expenses, cash interest expenses and capital expenditures, to (ii) the Company’s gross profits (the “Original Ratios”). The Company did not meet the required Original Ratio of 3.5 for the quarter ended September 30, 2015.
On December 7, 2015, the Company and the Lenders entered into the Second Amendment to the Loan and Security Agreement (the “Second Amendment”), which became effective on December 22, 2015, concurrent with the completion of the Company’s offering of Series C Preferred Stock described below. The Second Amendment replaced the Original Ratios in their entirety with a requirement that the Company maintain, as of the last day of each fiscal quarter of the Company beginning in the first fiscal quarter of 2016, a minimum adjusted cash flow (the “Cash Flow Requirement”) which requirement increases each quarter. For example, in the first fiscal quarter of 2016, the Company must maintain negative adjusted cash flow of not less than $6.5 million. The Cash Flow Requirement requires that the Company achieve a positive adjusted cash flow of $0.2 million by the last day of the quarter that begins on October 1, 2017. If the Company fails to satisfy the required Cash Flow Requirement for any two out of three successive quarters, the date on which the first amortization payment is due under the Loan Agreement would accelerate to the next following payment date, and the minimum quarterly amortization rate would increase to approximately $3.3 million, resulting in a final, accelerated maturity for the term loan by the end of the sixth fiscal quarter thereafter.
The Second Amendment also modified the provisions of the Loan Agreement allowing for the advance of additional term loans, subject, in each case to the Company’s continued compliance with the terms and conditions of the Loan Agreement and no material adverse changes in the Company having occurred. Pursuant to the Second Amendment, the Company will now receive an additional advance of a term loan in an amount up to $5,000,000 if the Company achieves, before May 14, 2016: (i) trailing six month revenue of at least $12,000,000 in any previous, consecutive 6 month period; (ii) at least 100 cumulative new unit placements during any consecutive 12 month period after January 1, 2015 (the date on which the Company achieves, before May 14, 2016, both such revenue and such placements, the “Milestone Date”); and (iii) the applicable Cash Flow Requirement for each fiscal quarter during the applicable draw period. The Company also will receive another advance in an amount up to $5,000,000 if: (i) the Company submits a 510(k) premarket notification submission to the FDA concerning its diagnostic tests of its next generation product platform (currently in development) before September 30, 2016; (ii) the Company also achieves the applicable Cash Flow Requirement for each fiscal quarter during the applicable draw period; and (iii) if the Company has satisfied both of the foregoing tests, it has submitted its draw request on or before November 15, 2016.
Substantially all assets of the Company serve as collateral to the Loan Agreement. The Loan Agreement restricts our ability to pay cash dividends and certain other payments. The Loan agreement also provides that a material adverse change in the Company’s financial condition could trigger an event of default. If an event of default occurs all amounts owing under the Loan Agreement would become immediately due and payable and the Collateral Agent, could move against the collateral, including the Company’s cash and cash equivalents. While the Company does not believe that such an event of default has occurred, the Lenders may take a contrary position. If an event of default were to occur, such actions by the Collateral Agent would have an immediate and substantial negative effect on the Company’s ability to continue as a going concern, as it would essentially eliminate its cash reserves. The Company has not been notified of an event of default as of the date of issuance of these financial statements. As there is a more than remote likelihood that the Lenders may be entitled to declare an event of default under this clause in the next twelve months, the principal due subsequent to December 31, 2015 have been presented as a current liability.
In consideration of the replacement of the Original Ratios and modifications to the terms governing the subsequent advance of loans under the Loan Agreement, the Second Amendment also provides that: (i) the minimum account balance in the Company’s accounts that are subject to a control agreement in favor of the Collateral Agent, which was $4 million prior to the effectiveness of the Second Amendment, is increased to $5 million upon the earlier to occur of the Milestone Date or May 14, 2016 (which occurred on February 5, 2016), and (ii) the Company shall issue warrants to the Lenders exercisable for an aggregate of 500,000 shares of the Company (the “Additional Lender Warrants”). The Additional Lender Warrants have an exercise price of $0.01 per share and are exercisable for a period of 10 years until December 22, 2025. At the time of issuance, the relative fair value of the Additional Lender Warrants was estimated at $0.4 million and recorded as a debt discount. The Company applied the 10% cash flow test pursuant to ASC 470 to calculate the difference between the present value of the amended Loan's cash flows and the present value of the original Loan's remaining cash flow and concluded that the results didn't exceed the 10% factor, the debt modification is not considered substantially different and did not apply extinguishment accounting, rather accounting for the modification on a prospective basis pursuant to ASC 470. The carrying amount of the Loan is not adjusted and the effects of the changes are to be reflected in future periods. The revised effective interest rate of the modified loan is approximately 22.0%

Series A Convertible Preferred Stock Offering
On May 14, 2015, the Company issued $4.4 million of series A convertible preferred stock (the "Series A Preferred Stock"), which are convertible into a total of 1,168,659 shares of common stock at a conversion price of $3.765, and warrants to purchase shares of common stock exercisable for up to 1,168,659 additional shares of common stock, in the aggregate at exercise price of $3.65 per share and are exercisable for a period of 5 years commencing November 14, 2015 until November 14, 2020 (the "Series A Investor Warrants").

The Series A Warrants are exercisable for 4.5 to 5 years commencing November 14, 2015. At the time of issuance, the relative fair value of the Series A Investor Warrants was estimated at $1.6 million using the Black-Scholes model and recorded as issuance costs. The Series A Preferred Stock is perpetual and does not have a required dividend right or voting rights and has a liquidation preference of $0.01 per share. As of December 31, 2015, all 4,400 shares of Series A Preferred Stock had been converted into 1,168,659 shares of common stock.
Net proceeds from the Series A Offering after placement agent fees and other offering expenses were approximately $4.0 million.
Series B Convertible Preferred Stock Offering
On June 11, 2015, the Company issued $4.4 million of series B convertible preferred stock (the “Series B Preferred Stock”) (which are convertible into a total of 1,203,800 shares of common stock at a conversion price of $3.655) and warrants to purchase shares of common stock exercisable for up to 1,203,800 additional shares of common stock, in the aggregate at an exercise price of $3.54 per share and are exercisable for a period of 5 years commencing December 11, 2015 until December 11, 2020 (the “Series B Investor Warrants”).

The Series B Warrants are exercisable for 4.5 to 5 years commencing December 11, 2015. At the time of issuance, the relative fair value of the Series B Investor Warrants was estimated at $1.6 million using the Black-Scholes model and recorded as issuance costs.

Common Stock and Series C Convertible Preferred Stock Offering
On December 22, 2015, the Company completed a registered offering in which it issued 2,298,744 shares of its common stock at a price of $0.47 per share, with each share of common stock coupled with a 5-year warrant to purchase one share of common stock, at an exercise price of $0.70 per share and are exercisable for a period of 5 years until December 22, 2020 (the “Series C Investor Warrants”). These securities were sold in the form of a Class A Unit but were immediately separable and were issued separately at the closing.
For certain investors who would otherwise hold more than 4.99% of the Company’s common stock following the registered Offering, the Company issued to such investors, in the form of Class B Units, 8,919.59044 shares of a new class of preferred stock designated Series C Convertible Preferred Stock (the “Series C Preferred Stock”) with a stated value of $1,000 and which are convertible into 18,977,852 shares of the Company’s common stock at a conversion price equal to $0.47 per share of common stock, together with Series C Investor Warrants to purchase up to 18,977,852 shares of the Company’s common stock. These securities were sold in the form of a Class B Unit but were immediately separable and were issued separately at the closing.
In connection with the Series C Offering, and as partial payment of the placement agent’s fees in connection therewith, the Company issued to the placement agent and certain of its principals warrants to purchase an aggregate of 1,276,596 shares of common stock at an exercise price of $0.517 per share (the "Series C Placement Agent Warrants", and together with the Series C Investor Warrants, the "Series C Warrants") with a fair value of $0.7 million at issuance. The Series C Warrants were exercisable immediately upon issuance. At the time of issuance, the relative fair value of the Series C Investor Warrants was estimated at $10.5 million using the Black-Scholes model and recorded as issuance costs. The Series C Preferred Stock is perpetual and does not have a required dividend right or voting rights and has a liquidation preference of $0.01 per share. As of December 31, 2015, 487.790 shares of Series C Preferred Stock had been converted into 1,037,852 shares of common stock.
Net proceeds from the Series C and Unit A Offering after placement agent fees and other offering expenses was approximately $8.1 million, and $1.0 million, respectively.

The Lender Warrants, Series A Warrants, Series B Warrants and Series C Warrants can be settled in shares of our common stock by cashless exercise in lieu of payment of the exercise price at the option of the holder. The warrants contain no mandatory redemption features and no repurchase obligations requiring the transferring of assets and are for a fixed number of shares, except for customary anti-dilution adjustments.

5. Net Loss Per Common Share
Net Loss Per Common Share - Basic and diluted net loss per common share have been calculated in accordance with ASC Topic 260, “Earnings Per Share”, for the years ended December 31, 2015, and 2014. Since the Company had a net loss in each of the periods presented, basic and diluted net loss per common share are the same.
The computation of basic net loss per common share for the years ended December 31, 2015, and 2014 excluded zero shares of restricted stock for each year respectively. While these restricted shares of stock are included in outstanding shares on the balance sheet at December 31, 2015 and 2014, these restricted shares are excluded from basic net loss per common share in accordance with ASC Topic 260 due to the forfeiture provisions associated with these shares.
The computations of diluted net loss per common share for the years ended December 31, 2015, and 2014 did not include the outstanding shares of restricted stock as well as the effects of the following options to acquire common stock and common stock warrants as the inclusion of these securities would have been antidilutive:

6. Equity Incentive Plans
The Company’s board of directors has adopted and the shareholders have approved the Nanosphere, Inc. 2000 Equity Incentive Plan (the “2000 Plan”), the Nanosphere, Inc. 2007 Long-Term Incentive plan (the "2007 Plan") and the Nanosphere, Inc. 2014 Long-Term Incentive Plan (the "2014 Plan" and together with the 2000 Plan and the 2007 Plan, the "Plans"). Upon adoption of the 2014 Plan at the Company's annual meeting of shareholders on May 28, 2014, the 2000 Plan and 2007 Plan were terminated. The Plans authorized the compensation committee to grant stock options, share appreciation rights, restricted shares, restricted share units, unrestricted shares, incentive stock options, deferred share units and performance awards. Option awards are generally granted with an exercise price equal to or above the fair value of the Company’s common stock at the date of grant with ten year contractual terms.
As of December 31, 2015, there are 781,223 shares remaining in the 2014 Plan available for grants.

Certain options vest ratably over two or four years of service, while other options vest after seven years of service but provide for accelerated vesting contingent upon the achievement of various company-wide performance goals, such as decreasing time to market for new products and entering into corporate collaborations (as defined in the option grant agreements). For these “accelerated vesting” options, 20-25% of the granted option shares will vest upon the achievement of each of four or five milestones as defined in the option grant agreements, with any remaining unvested options vesting on the seven year anniversary of the option grant dates. Approximately 3.2% of the options granted and outstanding contain “accelerated vesting” provisions. The service period over which compensation expense is recognized for options which include the accelerated vesting provision is the shorter of the seven year cliff term or the projected timeframe for achieving the company-wide performance goals.
The fair values of the Company’s option awards were estimated at the dates of grant using the Black-Scholes option pricing model with the following assumptions:

$0.49 to $3.40

 
$
17.40

Estimated forfeiture rate

%
The expected volatility for option awards granted during 2015 and 2014 was based on the Company’s actual historical volatility. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of the grants for periods consistent with the expected life of the option. The expected life of options that vest ratably over two or four years of service is derived from historical experience of previously granted awards. The Company estimates the expected life of options with accelerated vesting terms giving consideration to the dates that the Company expects to achieve key milestones under the option agreements and the term of the option. Total compensation cost associated with the option awards was $1.0 million and $1.6 million, in 2015 and 2014, respectively.

53


As of December 31, 2015, the total compensation cost not yet recognized related to the nonvested awards is approximately $1.4 million, which is expected to be recognized over the next 0.9 years, which is a weighted average term. Certain milestone events are deemed probable of achievement prior to their seven year vesting term, and the acceleration of vesting resulting from the achievement of such milestone events has been factored into the weighted average vesting term. While the Company does not have a formally established policy, as a practice the Company has delivered newly issued shares of its common stock upon the exercise of stock options.

7. Preferred Stock
Series A Convertible Preferred Stock
The Company issued and sold 4,400 shares of Series A Preferred Stock to the Investors on May 14, 2015. The Series A Preferred Stock, par value $0.01, was sold for $1,000 per share and was convertible at any time at the holder’s option, converted in a series of transactions in May and June 2015, at a conversion rate of $3.765 per share into 1,168,659 shares of the Company's common stock.
In a concurrent private placement, the Company issued the Series A Warrants to the Investors and the placement agent for the Series A Offering, which are exercisable into up to 1,238,779 shares of our common stock with the 1,168,659 Series A Investor Warrants having an exercise price of $3.65 per share and the Series A Placement Agent Warrants having an exercise price of $4.45 per share, in each case subject to certain customary anti-dilution adjustments. The Series A Investor Warrants are

54


exercisable at any time between November 14, 2015, and November 14, 2020. The Series A Placement Agent Warrants are exercisable at any time between November 14, 2015 and May 14, 2020. The Series A Warrants can be settled in shares of our common stock by cashless exercise in lieu of payment of the exercise price at the option of the investors if the underlying shares are not then registered for resale. The Series A Warrant holders will participate in any dividends declared and paid to common stock holders on an ‘as-exercised’ basis, and will be held in abeyance until the warrants are exercised.
The Company has determined that the Series A Warrants qualify for accounting as equity instruments rather than as liabilities. As of the May 14, 2015, issuance date, the Company estimated the fair value of the Series A Investor Warrants at $3.2 million under the Black-Scholes option pricing model using the following primary assumptions: contractual term of 5.5 years, volatility rate of 77.26%, risk-free interest rate of 1.62% and expected dividend rate of 0%. Based on the Series A Investor Warrant’s relative fair value to the fair value of the Series A Preferred Stock, $1.6 million of the $4.4 million of proceeds was allocated to the Series A Investor Warrants, creating a corresponding preferred stock discount in the same amount.  
The Company assessed the Series A Preferred Stock and the related Series A Warrants under ASC Topic 480, “Distinguishing Liabilities from Equity” (“ASC 480”), ASC Topic 815, “Derivatives and Hedging” (“ASC 815”), and ASC Topic 470, “Debt” (“ASC 470”). The preferred stock contains an embedded feature allowing an optional conversion by the holder into common stock which meets the definition of a derivative. However, we determined that the preferred stock is an “equity host” (as described by ASC 815) for purposes of assessing the embedded derivative for potential bifurcation and that the optional conversion feature is clearly and closely associated to the preferred stock host; therefore the embedded derivative does not require bifurcation and separate recognition under ASC 815. We determined there to be a beneficial conversion feature (“BCF”) requiring recognition at its intrinsic value. Since the conversion option of the preferred stock was immediately exercisable, the amount allocated to the BCF was immediately accreted to preferred dividends, resulting in an increase in the carrying value of the preferred stock. We also assessed the Series A Warrants under ASC 815 and determined that they did not initially meet the definition of a derivative, but will require evaluation on an on-going basis. As of December 31, 2015, we determined that the warrants still did not meet the definition of a derivative and continued to qualify for equity recognition.
On May 14, 2015, the Company recorded a deemed dividend of $2.2 million related to the beneficial conversion feature with the issuance of the Series A Convertible Preferred stock.
As of December 31, 2015, all Series A Preferred Stock had converted to common stock. Upon conversion the Company recorded an additional deemed dividend of $1.6 million.
Series B Convertible Preferred Stock
The Company issued and sold 4,400 shares of Series B Preferred Stock on June 11, 2015. The Series B Preferred Stock, par value $0.01, was sold for $1,000 per share and is convertible at any time at the holder’s option and converted in a series of transactions in June and September 2015, at a conversion rate of $3.655 per share (subject to certain, customary anti-dilution provisions) into 1,203,800 shares of the Company's common stock.
In a concurrent private placement, the Company issued the Series B Warrants to the Investors and the placement agent for the Series B Offering for no additional consideration. The Series B Warrants are exercisable into up to 1,276,060 shares of our common stock at an exercise price of $3.54 per share (subject to certain, customary anti-dilution provisions). The Series B Investor Warrants are exercisable at any time between December 11, 2015, and December 11, 2020. The Series B Placement Agent Warrants are exercisable at any time between December 11, 2015, and June 08, 2020. The terms of the Series B Warrants and related registration rights agreement are otherwise identical to those of the Series A Warrants. As of the June 11, 2015 issuance date, the Company estimated the fair value of the Series B Investor Warrants at $2.9 million under the Black-Scholes option pricing model using the following primary assumptions: contractual term of 5.5 years, volatility rate of 77.36%, risk-free interest rate of 1.82% and expected dividend rate of 0%. Based on the Series B Investor Warrant’s relative fair value to the fair value of the Series B Stock, $1.6 million of the $4.4 million of proceeds was allocated to the Series B Investor Warrants, creating a corresponding preferred stock discount in the same amount.
We assessed the Series B Preferred Stock and Series B Warrants using the same methodology as for the Series A Preferred Stock and Series A Warrants(see discussion above), and resulting in the same determinations.
On June 8, 2015, the Company recorded a deemed dividend of $1.5 million related to the beneficial conversion feature with the issuance of the Series B Convertible Preferred stock.
As of December 31st, 2015 all Series B Preferred Stock had converted to common stock. Upon conversion the Company recorded an additional deemed dividend of $1.6 million.
Common Stock and Series C Convertible Preferred Stock

On December 22, 2015, the Company completed a registered offering in which it issued 2,298,744 shares of its common stock at a price of $0.47 per share, with each share of common stock coupled with a five years warrant to purchase one

55


share of common stock, at an exercise price of $0.70 per share and are exercisable for a period of 5 years until December 22, 2020 (the “Series C Investor Warrants”). These securities were sold in the form of a Class A Unit but were immediately separable and were issued separately at the closing.

For certain investors who would otherwise hold more than 4.99% of the Company’s common stock following the registered Offering, the Company issued to such investors, in the form of Class B Units, 8,919.59044 shares of a new class of preferred stock designated Series C Convertible Preferred Stock with a stated value of $1,000 and which are convertible into 18,977,852 shares of the Company’s common stock at a conversion price equal to $0.47 per share of common stock, together with Series C Investor Warrants to purchase up to 18,977,852 shares of the Company’s common stock. These securities were sold in the form of a Class B Unit but were immediately separable and were issued separately at the closing.
In connection with the Series C Offering, and as partial payment of the placement agent’s fees in connection therewith, the Company issued to the placement agent and certain of its principals warrants to purchase an aggregate of 1,276,596 shares of common stock at an exercise price of $0.517 per share and are exercisable for a period of 5 years until December 22, 2020 (the “Series C Placement Agent Warrants,” and together with the Series C Investor Warrants, the “Series C Warrants”). The Series C Warrants were exercisable immediately upon issuance. As of the December 22, 2015, issuance date, the Company estimated the fair value of the Series C Investor Warrants at $10.5 million under the Black-Scholes option pricing model using the following primary assumptions: contractual term of 5 years, volatility rate of 95.34%, risk-free interest rate of 1.71% and expected dividend rate of 0%. Based on the Series C Investor Warrant’s relative fair value to the fair value of the Series C Preferred Stock, $3.2 million of the $8.9 million of proceeds was allocated to the Series C Investor Warrants, creating a corresponding preferred stock discount in the same amount.
We assessed the Series C Preferred Stock and Series C Warrants using the same methodology as for the Series A Preferred Stock and Series A Warrants (see discussion above), and resulting in the same determinations.
On December 22, 2015 the Company recorded a deemed dividend of $5.1 million related to the beneficial conversion feature with the issuance of the Series C Convertible Preferred stock.
As of December 31, 2015, 487.79 shares of Series C Preferred stock had been converted to common stock. Upon conversion the Company recorded an additional deemed dividend of $0.2 million.
8. Stockholders’ Equity
Common Stock
On October 27, 2014, the Company completed an underwritten public offering of 2,000,000 shares of our common stock at a public offering price of $10.00 per share. As part of the fee payable to the underwriters in connection with the offering, we also issued 20,000 shares of common stock to the underwriters. The Company received net proceeds of approximately $18.5 million from the offering after deducting underwriting discounts and commissions and offering expenses.

12. Income Taxes
Deferred tax assets consist primarily of net operating loss (“NOL”) carryforwards related to U.S. federal and state taxes and research and development ("R&D") tax credits. Realization of future tax benefits related to deferred tax assets is dependent on many factors, including the Company’s ability to generate future taxable income. Due to the Company’s history of operating losses, the Company has recorded a full valuation allowance against these assets.
NOL carryforwards of approximately $347.0 million for income tax purposes are available to offset future taxable income. If not used, these carryforwards will expire in varying amounts from 2020 through 2035. The Company also has federal research and development tax credit carryforwards of $13.9 million which will expire from 2020 through 2035. Sections 382 & 383 of the Internal Revenue Code subjects the utilization of net operating loss and credit carryforwards to an annual limitation that is applicable if the Company experiences an ownership change. The Company believes its public offerings and/or prior equity investments likely have triggered an ownership change as defined by the Internal Revenue Code. However, the Company has yet to perform the computations under Sections 382 & 383 which would determine the amount of annual limitation on its utilization of its net operating loss and tax credit carryforwards. The annual limitation may result in an annual usage limitation that would require the Company to write off part or all of the NOL or R&D credit carryforward. This impairment would have no impact on the effective tax rate as the Company maintains a full valuation allowance.

14. Subsequent Events
On January 25, 2016, the Company received a deficiency letter from the Listing Qualifications Department of The NASDAQ Stock Market (the “Staff”), notifying it that, for the last 30 consecutive business days, the closing bid price of its common stock has not been maintained at the minimum required closing bid price of at least $1.00 per share as required for continued listing on The NASDAQ Capital Market pursuant to Listing Rule 5550(a)(2) (“Minimum Bid Price Rule”). In accordance with NASDAQ Listing Rules, the Company has been given 180 calendar days, or until July 25, 2016, to regain compliance with the Minimum Bid Price. If, at any time before July 25, 2016 the closing bid price of the Company’s common stock is at least $1.00 for a minimum of 10 consecutive business days, the Staff will provide written notification to the Company that we comply with the Minimum Bid Price Rule. During this 180 calendar day period, the Company also may submit a plan to regain compliance to NASDAQ and may request up to an additional 180 calendar days to complete the plan.
On January 31, 2016, the company achieved both (i) trailing six month revenue of greater than $12,000,000 in a consecutive 6 month period, and (ii) greater than 100 cumulative new unit placements during a consecutive 12 month period after January 1, 2015, pursuant to which, on February 5, 2016, the Company was able to draw an advance on the term loan in the amount of $5 million. This advance also requires that the minimum account balance in the Company’s accounts that are subject to a control agreement in favor of the Collateral Agent, increase to $5 million.

60


From January 1, 2016 through February 23, 2016, an additional 282.00 shares of Series C Preferred Stock had been converted into 600,000 shares of common stock.

Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure.
We have had no disagreements with our independent registered public accounting firm on any matter of accounting principles or practices or financial statement disclosure.
Item 9A. Controls and Procedures.
(a)Evaluation of Disclosure Controls and Procedures
Management of the Company, with the participation of the Chief Executive Officer and the Interim Chief Financial Officer, evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended) as of December 31, 2015. The Company’s disclosure controls and procedures are designed to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported on a timely basis and that such information is accumulated and communicated to management, including the Chief Executive Officer and Interim Chief Financial Officer, as appropriate, to allow timely decisions regarding disclosure. Based upon this evaluation, the Chief Executive Officer and the Interim Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective as of December 31, 2015.
(b)Management’s Report on Internal Control Over Financial Reporting
Internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, is a process designed by, or under the supervision of, the Company’s Chief Executive Officer and Interim Chief Financial Officer, or persons performing similar functions, and effected by the Company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Company’s management, with the participation of the Company’s Chief Executive Officer and Interim Chief Financial Officer, has established and maintained policies and procedures designed to maintain the adequacy of the Company’s internal control over financial reporting, and includes those policies and procedures that:
 
(1)
Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;
(2)
Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and
(3)
Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.
The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f). The Company’s management conducted an evaluation of the effectiveness of internal control over financial reporting based on the framework in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on its evaluation under the framework in Internal Control — Integrated Framework (2013), the Company’s management concluded that internal control over financial reporting was effective as of December 31, 2015.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree or compliance with the policies or procedures may deteriorate.
(c)Changes in Internal Controls Over Financial Reporting
There have been no changes to the Company’s internal control over financial reporting during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
