We are a leading technology company that combines advanced cloud-based data analytics and data-driven intervention platforms to achieve meaningful insight and improvement in clinical and quality outcomes, utilization, and financial performance across the healthcare landscape.

Our powerful platform drives high-value impact, improving quality and economics for health plans, hospitals, physicians, patients, pharmaceutical and life sciences companies, and researchers. The value we deliver to our clients is achieved by turning data into insights and those insights into action. Through our large proprietary datasets, advanced integration technologies, sophisticated predictive analytics, and subject matter expertise, we deliver seamless, end-to-end platforms that bring the benefits of big data and large-scale analytics to the point of care. Our analytics identify gaps in care, quality, data integrity, and financial performance, while providing clients with differentiated capabilities to resolve these gaps. During 2015, we provided these services to hundreds of clients, providing analytics informed by our data and insight, from our MORE² Registry®, on more than 784,000 physicians, 269,000 clinical facilities, 130 million unique patients (covering approximately 98.2% of all U.S. counties and Puerto Rico), and 11.0 billion medical events, a number that has been increasing at a rate of approximately 2.9% compounding monthly, or 40.9% annually, since 2000.

Healthcare costs in the United States have been increasing significantly for many years, currently over $3 trillion annually. This rise in healthcare costs has driven a broad transition from consumption-based payment models to value-based payment models across the healthcare landscape. As a result, the specific disease and comorbidity status, clinical and quality outcomes, resource utilization, and care details of the individual patient have become increasingly relevant to the various constituents of the healthcare delivery system. Concurrently, the count and complexity of diseases, diagnostics, and treatments—let alone payment models and regulatory oversight requirements—have soared. In this setting, granular data has become critical to determining and improving quality and financial performance in healthcare.

At the core of our enabling capabilities is a long history of innovation and profitable growth, positioning us to deliver value to our clients and capitalize on the confluence of recent changes in the healthcare industry that many describe as historically unprecedented. Our ability to rapidly innovate is enabled by the depth and breadth of our industry expertise, large-scale proprietary datasets, advanced analytical prowess, highly flexible platform components, a common native code base, and experience across the entire healthcare landscape.

The value we deliver to our clients through our data analytics and intervention platforms are comprised of four primary components:

Our ability to deliver value to our clients through our advanced analytics and intervention platforms has allowed us to achieve significant growth since our company's organization. For the year ended December 31, 2015, our revenue was $437.3 million, representing 21% growth over the year ended December 31, 2014. In this same period, we generated Adjusted EBITDA of $151.6 million, representing 35% of revenue and 13% growth over the same period in the prior year. Net income for the year ended December 31, 2015 was $66.1 million, representing 15% of revenue and a 1% increase over the same period in 2014. Non-GAAP net income for the year ended December 31, 2015 was $75.4 million, representing 17% of revenue and a 7% increase over the same period in 2014. Adjusted EBITDA and Non-GAAP net income are measures that are not presented in accordance with accounting principles generally accepted in the United States (GAAP). For a reconciliation of net income to Adjusted EBITDA and Non-GAAP net income, see "Non-GAAP Financial Measures," provided in Item 6—Selected Financial Data.

In this Annual Report, unless we indicate otherwise or the context requires, references to the "Company," "Inovalon," "we," "our," "ours," and "us" refer to Inovalon Holdings, Inc. and its consolidated subsidiaries.

The Company was incorporated in the state of Delaware on September 11, 2014. Effective September 17, 2014, in order to facilitate the administration, management, and development of our business and our initial public offering, Inovalon, Inc., which was incorporated in the state of Delaware on November 18, 2005, implemented a holding company reorganization, pursuant to which we became the new parent company and Inovalon, Inc. became our direct, wholly owned subsidiary.

On February 18, 2015, we completed our initial public offering (the "IPO") of 22,222,222 shares of Class A common stock and, upon the underwriters' exercise of their option to purchase additional shares, issued an additional 3,142,581 shares of Class A common stock for a total of 25,364,803 shares issued. All of the shares issued in the IPO were primary shares offered by us as none of our stockholders sold any shares in the IPO. The offering price of the shares sold in the IPO was $27.00 per share, resulting in net proceeds to us, after underwriters' discounts and commissions and other expenses payable by us, of approximately $639.1 million.

On September 1, 2015, pursuant to the terms of a Share Purchase Agreement (the "Purchase Agreement") between the Company and Avalere Health, Inc. ("Avalere"), we acquired 100 percent of the capital stock of Avalere for an aggregate stated purchase price of $140.0 million, consisting of cash and 235,737 shares of the Company's Class A common stock which are subject to resale restrictions. Avalere is a provider of data-driven advisory services and business intelligence solutions primarily to the pharmaceutical and life sciences industry. Pursuant to the Purchase Agreement, certain portions of the stated purchase price of $140.0 million are contingent upon the achievement of financial and operational objectives, and other portions are subject to continued employment provisions. The addition of Avalere, with its more than 200 pharmaceutical and life sciences clients, as well as an extensive array of client relationships with payors, providers and research institutions, is expected to expand our capabilities and client base into the expansive and adjacent markets of the pharmaceutical and life sciences industry. See Note 3 (Business Combinations), included elsewhere within this annual report on Form 10-K for more information.

On September 29, 2015, we announced the introduction of Data Diagnostics™ to the healthcare marketplace. This technology, the latest in our product portfolio releases, provides a suite of hundreds of patient-specific analyses that can be ordered individually by clinicians on demand with the answer provided within seconds—all without leaving the clinician's workflow. The capability leverages vast amounts of data across billions of medical events, interconnectivity, and high-speed cloud-based analytics to allow physician organizations, health plans, accountable care organizations (ACOs), hospitals, integrated healthcare delivery systems, ASO employer groups, government programs, and individual physicians to achieve valuable clinical insights, strong clinical and quality outcomes, utilization efficiency, and overall financial performance on demand and in real time. The technology is delivered in collaboration with Quest Diagnostics, the nation's largest laboratory organization, providing large-scale distribution to clinicians through Quest's more than 200,000 Care360® provider portal installations and more than 400 integrated EHR platforms serving approximately half of the physicians and hospitals in the United States. We have been investing resources as part of the development and anticipated operation and support of Data Diagnostics™ since our second fiscal quarter of 2015 and this continued during the third quarter and accelerated significantly in the fourth quarter of 2015 as we ramp for operational activity within the Data Diagnostic platform. While still in the early stages of this platform's introduction, initial feedback from the marketplace has been very positive.

We believe that the increasing demand for our platform is driven by the confluence of four fundamental healthcare industry trends:

Unsustainable Rise in Healthcare Costs. Healthcare spending in the U.S. increased 5.3% on a year-over-year basis to over $3 trillion in 2014 according to the 2014 National Health Expenditure Highlights prepared by the Centers for Medicare and Medicaid Services, or CMS, representing more than 17% of U.S. Gross Domestic Product, or GDP. The 2015 set of healthcare cost projections from the Congressional Budget Office, or the CBO, indicate national healthcare spending will rise to about 25% of GDP by 2040. To address this expected significant rise in healthcare costs, the U.S. healthcare market is seeking more efficient and effective methods of delivering care. This same trend is playing out across modernized nations around the globe.

Shift to Value-Based Healthcare. The traditional fee-for-service reimbursement model in healthcare has played a major role in elevating both the level and growth rate of healthcare spending. In response, both the public and private sectors are shifting away from the historical fee-for-service models toward value-based, capitated payment models that are designed to incentivize value and quality at an individual patient level. The number of Americans covered by capitated payment programs (care programs wherein an organization is financially responsible for the healthcare of a population of patients for which the total compensation is fixed other than adjustments for factors including specifically how sick individual patients are, how much resource is needed to be applied or spent on each patient, what is the quality of the clinical care, and other demographic factors) has been increasing rapidly and, according to industry sources and our internal estimates, is anticipated to increase from approximately 80 million at the start of 2014 to over 150 million by 2019. This increase is expected to further drive the critical importance to accurately measure, analyze, report, and improve patient disease and comorbidity conditions, utilization rates, and clinical quality outcomes.

Digitization of Healthcare Information. Across the healthcare landscape, a significant amount of data is being created every day driven by patient care, payment systems, regulatory compliance, and record keeping. These data include information within patient health records, clinical trials, pharmacy benefit programs, imaging systems, sensors and monitoring platforms, laboratory results, patient reported information, hospital and physician performance programs, and billing and payment processing. Despite significant investments by public and private sources within the industry, however,

the digitized healthcare data remain largely stored in "walled gardens"—data that is static and not easily shared or interpreted. As the amount of data in healthcare continues to grow, we believe that it will be critical for the healthcare industry to be able to use this disparate data to better achieve the goals of higher quality and more efficient care.

Increasing Complexity. The healthcare industry is on a course of dramatically progressive complexity. As technology employed in the healthcare space has become increasingly sophisticated, new diagnostics and treatments have been introduced, the pool of clinical research has expanded, and the paradigms dictating payment and regulatory oversight have multiplied. This expanding complexity drives a growing and continuous need for analysis of the underlying and resulting data.

We believe that our opportunity is significant and growing. According to a January 2013 McKinsey report, utilizing data analytics could reduce healthcare costs in the United States by an estimated $300 billion to $450 billion, or 12% to 17% of total U.S. healthcare costs today.

The ability to aggregate, integrate, and analyze data in massive scale and apply garnered insights in a manner that achieves meaningful impact is crucial for healthcare payors (e.g., health plans and integrated health delivery systems), clinical providers (e.g., hospitals, ACOs, and physicians), pharmaceutical and life sciences companies, and consumers. We estimate that our addressable market for these capabilities serving these healthcare constituents to be approximately $83.8 billion. We believe that the market opportunity for our current platform offering within the payor market, the historical focus of our company, is approximately $10.6 billion. According to industry sources, the market for software and related services is approximately $14.0 billion within the U.S. payor market. We believe that as analytics continue to demonstrate greater value within the U.S. payor landscape, the market will expand commensurately. As we continue to build and launch new capabilities, we believe it will provide a significantly larger value opportunity within this same payor space. For providers, industry sources estimate that software and related services represent a $32.3 billion U.S. market size. In the global pharmaceutical and life-sciences market, International Data Corporation, or IDC, in a 2013 report, estimates a $30.9 billion market size for total software and services spend in 2013. In the consumer market, an October 2013 Research and Markets report estimated a $6.6 billion global market size for mobile health applications and solutions. As with our other market segments, we believe that analytics will also drive a significant expansion in the consumer market.

In addition, the pressures that face the U.S. healthcare market are not unique, as other communities around the world are facing aging populations and growing pressures in the sustainable affordability of healthcare. We believe that our capabilities are highly applicable to other developed and developing countries around the globe, which we believe represents a sizable related future opportunity for us.

Our platforms are informed by clinical insights through our combination of industry-leading subject matter expertise and extensive proprietary datasets. Through the application of our platforms, we help our clients achieve large- scale insight and meaningful improvement in clinical and quality outcomes, utilization, and financial performance.

In deploying our technology, our clients want us to synthesize opaque, convoluted, and disparate data into actionable information aligned with individualized goals and, in turn, empower a patient and provider intervention platform that achieves the realization of their goals in a measurable way.

Our platforms' capabilities are currently engaged by hundreds of clients that leverage our ability to analyze and improve clinical and quality outcomes and financial performance. These platforms are applied in a variety of environments.

Data Integration. Datasets and the management of data are part of our core strengths, which give us insight into how a patient, provider, or population is doing. It grants us both relative and absolute insight, and informs the construction of new capabilities, predictive models, and impact predictions. It speeds our time to client impact, decreases the burden on clients choosing to do business with us, and empowers our achievement of mission and results.

We believe that our enterprise-scale data integration and management processes are a critical capability in achieving a material improvement in clinical quality outcomes and financial performance in healthcare. We integrate data seamlessly and securely into our systems through our proprietary Extract, Transform, Load ("ETL") tools and processes. This system manages the process of defining and configuring thousands of industry data feeds from our clients and partners (such as electronic health records ("EHR"), laboratory, pharmacy, patient reported, claims, paper based medical records, biometric, and hospital data feeds respectively), manages the data processing workflow, and monitors the ongoing provision and quality of data through the application of more than 2,000 data integrity checks.

In addition to being maintained and tagged within client-specific data lakes, data we receive in the course of providing our services are statistically de-identified and stored in our MORE² Registry®. The MORE² Registry® goes beyond just claims data to include information about demographics, enrollment, diagnoses, procedures, pharmacy, laboratory results, and deep medical record clinical data and presents a significant representative mix of commercial, HIX Marketplace, Medicare Advantage, and managed Medicaid care plan patients. The following is a sample of various components within our MORE² Registry®.

Advanced Analytics. For years we have developed, honed, and scaled a portfolio of sophisticated analytics. Applying our team's subject matter expertise in computer processing, data architecture, statistics, medical sciences, healthcare policy, and leveraging the billions of medical events within our significant propriety datasets, we believe that we have developed one of the most advanced analytical platforms within the industry, as well as a culture and set of analytical toolsets that serve to rapidly innovate and expand our platform. Examples of the innovative analytics powered by this combination of data and processing capabilities include:

Intervention Platforms. Our data-driven intervention platforms are toolsets and services that enable our clients to take the insights derived from our analytics and implement solutions at the patient and provider level as being via hard copy and electronic mail, interconnected EHR systems, telephonic interactions, in patients' homes, through mobile devices, at dedicated patient centers, through web-enabled decision support tools, in retail pharmacies, and in traditional clinical locations, as examples) in order to achieve meaningful impact with the patient and provider. Some clients utilize our analytical outputs to achieve value on their own. Others license our data-driven intervention platform to support their ability to achieve data-driven impact. Yet others engage us to not only license our data-driven intervention platform, but also provide the personnel services necessary to leverage these toolsets and actually achieve the patient and provider-level impact. Examples of our data-driven intervention platform tools include:

Business Processing. Our business processing toolsets are made up of a powerful business intelligence system and comprehensive data warehousing to provide historical and current data insight, reporting, and benchmarking to support multiple client business needs such as government-mandated

data filings, financial planning, and compliance requirements. Examples of our business processing tools include:

Our objective is to continue to provide leading analytics and interventions platforms across the healthcare landscape while continuing to grow profitably. We intend to achieve this objective through the following key strategies:

Deliver Increasing Value to Existing Clients. We enjoy long term client relationships which entail multiple separate product engagements demonstrated by our average 5.0-year tenure for our top 10 clients with an aggregate of 66 separate statements of work as of December 31, 2015. Additionally, we have hundreds of client organizations that currently have only a limited number of services with us. Frequently we see clients that started with just one service with us realize the value that we are delivering and then expand their business with us to add additional services. We believe that we have a significant opportunity to deliver increasing value to our existing clients and this, in turn, will drive continued growth for us. As our clients recognize value and success as a result of working with our platforms, we frequently see them grow in their patient count and increase the number of products engaged with us—both of which result in our mutual success and growth. As we continue to deliver value to our clients, we plan to increase revenue from our existing clients by expanding their use of our platform, selling to other parts of their organizations, and selling additional analytical toolsets and services to them. Our pricing model allows us to grow incrementally along with our clients' growth. We are also able to introduce new healthcare plans that require additional functionality and insights as the

healthcare market becomes more complex and the regulatory environment evolves, providing us with a substantial opportunity to increase the value of our client relationships.

Continue to Grow Our Client Base. We believe that there is a substantial opportunity to continue to grow our client base. We intend to leverage our expertise and experience from the existing large client base to gain new clients through increased investment in our sales force and marketing efforts. In addition, by leveraging our sector expertise and thought leadership, we believe that we can increasingly become the partner of choice for our existing clients. The network effect created by delivering increasing client value and consequently expanding our brand and service value, coupled with our industry expertise, is also driving substantial inbound client interest.

Continue to Innovate. Our strength in applying advanced, big data, cloud- based data analytics and our proprietary datasets enable us to achieve increasingly more impactful results for our clients. In order to continue delivering meaningful results in clinical and quality outcomes, utilization, and financial performance across the healthcare landscape, we intend to continue to invest in research and development to further enhance our data analytics and intervention platforms. For example, we recently announced the launch of Data Diagnostics™, a suite of hundreds of real-time patient-specific data analyses that clinicians can order individually, on demand at the point of care within their existing workflow to identify and address gaps in quality, risk, utilization and medical history insights. Powered by Inovalon's sophisticated large-scale data interconnectivity and analytical platform, Data Diagnostics™ allow clinicians to order advanced analytics for their patients on-demand and, within seconds, receive results, for informed decision making during the patient encounter. We also announced during 2015, the acceleration of big data processing empowering our QSI® platform, enabling a significant functionality expansion in our clinical quality outcomes measurement capabilities supporting accelerated performance for HEDIS, Stars, QARR and other measurement and reporting standards. This advancement will also support the acceleration of our related predictive analytics capabilities. As a result, we expect our clients to experience significantly reduced cycle times, allowing for complex measure calculations at speeds which are more than 10 times faster than any other comparable solution which we are aware of in the healthcare industry.

Continue Expanding into Adjacent Verticals. We believe the application of advanced analytics and data extends well beyond our current market opportunities and provides additional adjacent market verticals for growth which include:

Expand Reach through Growing our Channel Partnerships. While we have been successful in growing our business through our direct sales efforts, we believe there is a significant opportunity that exists for us to further expand our reach through channel partnerships. There are many organizations in the healthcare space outside of the traditional payor and provider space that have meaningful impact on the quality of healthcare, such as retail clinics, pharmaceutical companies, CROs, large technology solution providers, and consulting firms. We believe our platform is well positioned to empower these organizations with powerful data-driven analytics and intervention insights, which can benefit their end consumers through improved care and better outcomes. For example, we launched a partnership with Walgreens, the nation's largest drugstore chain. This partnership has allowed us to leverage our proprietary data assets and distinctive analytics capabilities to bolster Walgreens' Clinics point-of-care solutions by providing clinicians with access to predictive insights about a patient's health status and data- driven intervention considerations, resulting in more efficient and higher quality standard of patient care while reducing the cost of care.

Continue to Leverage our Technology Partnerships. The healthcare industry has traditionally lagged behind the technology innovation curve. Big data and high-performance analytics frameworks have not yet been widely adopted by the healthcare industry. We have been a leader in the use of these high-performance technologies and analytics in the healthcare industry. We have been closely collaborating with EMC and their federated companies of VMware and Pivotal on numerous infrastructure projects to integrate and enable modern high-performance compute and storage frameworks at the point of care. Our advanced data processing and analytics capabilities, coupled with infrastructure thought leadership from leading vendors such as EMC has enabled us to empower our clients with powerful data-driven solution offerings and further transform the use case of modern technologies across the evolving IT healthcare landscape.

Expand Internationally. Governments, corporations, and consumers worldwide face similar pressures as within the U.S. with respect to their healthcare systems. We believe that our capabilities are highly applicable to other countries around the world and we intend to invest in replicating our success in the U.S. market to other strategic countries and regions.

Selectively Pursue Acquisitions. We plan to selectively pursue acquisitions of complementary businesses, technologies, and teams, such as our acquisition of Avalere, that we expect to allow us to add new features and functionalities to our platform and accelerate the pace of our innovation and expansion into adjacent market spaces beyond what we can achieve organically.

Leverage our Dynamic, Passionate, and Mission-Focused Culture. We believe that our work must meet a higher standard. We believe that the analytics that we design, deliver, and support achieve an impact in the lives of real people—parents, spouses, partners, siblings, and children—making integrity and quality cornerstones of our culture. Our dedication to integrity and quality extends to the proprietary technology used for medical data integration, analysis, abstraction, and reporting. Even more importantly, this culture is embraced throughout our company.

We hold ourselves to a high standard. We strive to ensure that each report, file, and dataset delivered to clients meets or exceeds superior standards of quality. We strive to ensure that each phone call, every patient encounter, and each customer encounter informed and supported by our analytics and platform meets or exceeds superior standards of quality. These values permeate our organization and drive our identity as a company that we believe drives growth and how we innovate, deliver our solutions to our clients, and attract and retain the best talent.

Throughout the healthcare industry, data is captured from many different sources, and while standards for exchanging information between healthcare applications are emerging, much of the data associated with population health remains in disparate silos, in various formats, on paper, and is both interchanged and processed without automation. Where investments have been made in the digitization of health data, many of the resulting solutions remain "walled gardens" of information—data that is static and not easily shared or interpreted.

Our big data technology platform was designed and developed to address these challenges. Our platform enables integration of any data source, on any hardware platform, in any data format at extremely high speeds. This advanced approach to delivering technology is comprehensive in that it provides for real-time capture, extremely rapid analytical processing and redistribution of health data. We believe that very few other healthcare technology platforms, if any, address the integration of the payor, the provider, and the patient, with high volume, at rapid velocity, with the same depth of data.

We believe that our big data capabilities enable us to receive, integrate, and process extremely large-scale data flows at truly industry-leading speeds, creating what we believe to be a material market differentiator and value creator for us and our clients. While data integration and processing at scale within the healthcare landscape (known for its highly disparate and "dirty" data characteristics) are key technology barriers to many organizations, we believe that we have made these capabilities a true differentiator—we are able to onboard clients and maintain high velocity computes in industry- leading times.

Our big data platform has been created through the use of internally created software coupled with industry-leading technology frameworks that are vendor- agnostic. We leverage modern big data frameworks such as Hadoop Distributed File System and Hadoop which enable our platform to store structured and unstructured data while making it readily accessible by our analytics engine. Our big data processing capabilities enable dramatic improvements in data integration and analytical cycle speed to value recognition to empower improvements for intelligent product development through the "real world" functional application. Our big data platform laid the foundation of the data fabric allowing integration into our analytical capabilities. We have moved analytics to the data instead of requiring the data to be brought to the analytics platform.

Our platform receives information from multiple external sources that are loaded into our "data lake" in its native format. Files may be received through secure FTP, web services, and direct connections to external systems. Loading the data into the data lake in its native format ensures that we maintain all data as it is received and allows users to query the data directly in its structured or unstructured format.

Processing data in its raw format presents many technological challenges. We have developed interactive data mapping technologies to support the mapping of the raw data files to staging structures used by our platform to convert data from its native format into a structured format that can be used by all processes on our platform. Once mapped, the data is run through multiple processes to standardize the data and perform data verification and integrity checks. For example, one source may provide person's gender using code values of "1" for male and "2" for female. Other clients may use values of "M" and "F" to represent the same data. Similarly, one source may send a specific laboratory result value as 7.25 while another source may fill in significant digits and send 7250. Our platform applies our data integrity analytics to convert the incoming data to values that are uniform across our entire platform.

Our technology platform is built upon modern big data frameworks such as Hadoop Distributed File System and Hadoop which enables our platform to store structured and unstructured data while making it readily accessible by our analytics engine.

Data access provided by our data lake leverages scalable application program interfaces, or APIs, and service based architecture techniques enabling access to the contextual data needed to perform many different types of analytics. An API is an application program interface, or software intermediary, that makes it possible for disparate systems to communicate and function with each other. Ultimately, data is provided to the analytics process and results are stored via service based requests to provide a scalable repository of source and results data.

We believe that our track record of service is the result of our commitment to excellence and our devotion to maintaining one of the industry's most sophisticated technology infrastructures. We have made significant investments over the past decade to build an industry-leading enterprise-scale infrastructure capable of managing the heavy computing and storage requirements of our data-driven business. Today, we employ a combination of owned, virtualized data centers along with hosted facilities to enable seamless, secure, and scalable solutions nationwide.

Our physical compute and storage infrastructure is deployed with a hybrid approach to cloud computing. Leveraging heavily virtualized infrastructure together with orchestration and automation

tools, we have achieved significant capabilities within our private cloud environment. The following diagram provides a high level overview of our key infrastructure elements.

We have a proven track record in implementing virtualization as our current datacenters are over 85% virtualized using VMware technologies. Operations of the virtualization technologies are streamlined by the orchestration, automation, and reporting capabilities provided by our private cloud and integration with public cloud service providers. These technologies will be used to provide computing, storage, and networking components to the hosting environment and provide operational efficiencies and cost optimization for the corporation.

In partnership with EMC, VMware, and Pivotal, we have implemented a sophisticated hybrid cloud and service based application stack design, enabling "burst" capacity architecture to allow provider-agnostic utilization of public cloud capacity if such capacity is required. Our virtualization technology has been integrated with automation and orchestration technology to create a cloud environment that provides both Infrastructure and Platform as Service capabilities. These service based capabilities allow us to dynamically expand our compute capacity in real time and provide the business with a cost effective and nimble platform. By leveraging both private and public cloud offerings, we can provide efficient, elastic, and cost effective compute resources based on the operational needs of our clients. We believe we are pioneers in the use of big data technology and high performance compute technology stack at the point of care in our industry.

Our platform is built utilizing an innovative enterprise infrastructure platform enabling robust performance scaling, strong security, high availability, and advanced business continuity options. The building blocks of this infrastructure consist of the following:

Our contingency program is designed to provide an immediate response and subsequent recovery from unplanned business disruptions. Supported by our Washington, DC Metro, Atlanta Metro, and Northern Virginia data centers, our contingency program provides a coordinated emergency response foundation across the organization. The program includes business continuity, emergency occupant, security incident response, and disaster recovery plans that encompass all areas of our technology and business operations. These interrelated processes align to provide maximum protection and risk mitigation. In addition to company-wide plans, specific details on event response and subsequent business recovery actions and activities are included within each respective business unit plan.

We maintain a central network operations center, or NOC, where systems are monitored to ensure proper operation and capacity utilization. The NOC monitors and collects information about a

multitude of technology operating metrics regarding system load and status. In conjunction with the rapid provisioning capability, automation, and standardization, the NOC provides us with the automated capabilities to oversee and manage our technology resources in order to meet business demands.

Protected health information is perhaps the most sensitive component of personal information. It is highly important that information about an individual's healthcare is properly and thoroughly protected from any inappropriate access, use and disclosure. Given the industry vertical in which we operate, we realize the importance of the safety and sensitivity of personal health information. We have been a trusted partner to our clients and are committed to ensuring the security and privacy of our client data, enterprise data, and our systems through the application of highly trained personnel, robust processes, and technology. Our privacy and security management includes:

Our platforms are composed of analytical and data-driven intervention components that collectively comprise a fully integrated suite of systems designed, developed, and maintained to achieve client value. The following are our key toolsets that we use to deliver our client solutions.

iPort™. iPort is our data integration and management process toolset. This proprietary toolset leverages a decade of dataset extraction, transform, and load experience, in combination with data format insights gained from analysis of our extensive MORE² Registry® dataset, to enable high volume data integration at enterprise scale. Applying more than 1,100 data integrity checks constructed from the analysis of data feeds that have constituted more than 11.0 billion medical events within the MORE² Registry®, iPort™ is able to manage data integration through an advanced exception rules processing—thus empowering both high throughput rates and accuracy. With data feed profiles monitoring for characteristics ranging from receipt timing, content, and format, to referential integrity, and trend consistency, iPort™ processes the integration of thousands of data feeds received by us while maintaining state-of-the-art security protocols and HIPAA compliance.

EHR Integration Engine. Our EHR interoperability is a capability that enables us to both (a) push patient-specific and provider-specific data and analytical results to EHR platforms, and (b) aggregate clinical data from patient-specific and provider-specific content within EHR platforms in a highly efficient manner. Designed to achieve these tasks within both cloud-based and single-install EHR

environments, our interoperability enables both the capture of clinical data and the delivery of data-driven interventions at the clinical point-of-care within the workflow of the clinical environment.

In addition to the innovative analytics capabilities discussed above under "—Our Platforms—Advanced Analytics," our data analytics platform includes the following key toolsets to facilitate our provision of data analytics services to our clients:

Predictive Clinical Insight System (PCIS™). PCIS™ identifies the diagnoses and comorbidities that may exist for a patient but which are incompletely or improperly reflected within the clinical profile of the patient as known to the patient's health plan. The PCIS™ system is designed to evaluate patients for undocumented conditions, worsening conditions, and uncoded conditions that are important for the effective ongoing management of the patient. Each of these gaps represents a potential incongruence between the "data picture" and the "true clinical picture" of the patient. These gaps, if unresolved, can prevent the proper care and resources to be directed to the respective patient, as well as cause health plans to recognize significant financial losses due to reimbursement inaccuracy, failed quality improvement goals, and utilization waste. Upon identifying each disease and comorbidity incongruence, PCIS™ generates and reports a potential impact, probability, and prioritization for the resolution of each gap. Evidence of unconfirmed diagnosis, worsening disease states, overlooked chronic conditions, implications of durable medical equipment, absences of coding specificity, and coding combinations are but a few examples of categorical analysis that are undertaken by PCIS™.

Quality Spectrum Insights Suite (QSI®, QSFD® and QSCL). These toolsets provide a flexible run-time engine and user-friendly tools for the design, development, and deployment of a broad set of healthcare data analytics across the spectrum of clinical and quality outcomes, healthcare utilization, spending patterns, provider and network performance, and patient risk profiles. The advanced graphical user interface (provided through Quality Spectrum Flowchart Designer, or QSFD®) empowers clients' clinical, product development, and research staff to achieve superior analytical functionality without having advanced statistical, epidemiological, or programming experience.

QSI® operates on both traditional relational database architectures, as well as on advanced big data architectures within the QSCL and QSI®-XL versions of the system. Core to its architecture is a proprietary Massively Parallel Processing (MPP) engine utilizing a Shared Nothing processing approach that scales linearly with additional processors, and a highly scalable grid storage array, enabling the development of an exceptional generation of toolsets driven by near-real time analytics across extremely large datasets.

Monthly Member Detail Map (MMDM™). The MMDM™ aggregates analytical outputs of other analytical toolsets to arrive at a coordinated gap resolution plan informing intervention strategies to resolve gaps in care, quality, and financial performance across large populations. To achieve this, the MMDM™ uses targeted patient-specific, site-specific, and provider-specific predictive analytics to enable and direct the right intervention for the right patient, in the right venue, at the right time. In addition to layering, prioritizing, and chronologically orchestrating data-driven intervention plans, the MMDM™ also enables the coexistence of Inovalon-driven analytics alongside client and third- party initiatives. The analytical processes necessary to assemble the separate outputs of other analytical toolsets and creating the MMDM™ output are highly complex but highly valuable in translating such disparate analyses into a practical operating plan to achieve positive impact for the provider and patient.

Data Diagnostics™. This technology provides a suite of hundreds of patient-specific analyses that can be ordered individually by clinicians on demand with the answer provided within seconds—all without leaving the clinician's workflow. The capability leverages vast amounts of data across billions of

medical events, interconnectivity, and high-speed cloud-based analytics to allow physician organizations, health plans, ACOs, hospitals, integrated healthcare delivery systems, ASO employer groups, government programs, and individual physicians to achieve valuable clinical insights, strong clinical and quality outcomes, utilization efficiency, and overall financial performance on demand and in real time.

ePASS®. Our electronic patient assessment solution suite, or ePASS®, is a web-enabled, point-of-care decision support tool designed to deliver both patient-level insight and guided clinical decision support. Through the use of ePASS®, the point-of-care clinical provider is able to access patient- specific information and is guided through data-driven topics for their consideration.

The ePASS® tool offers clinicians insight into the patient profile analytically compiled from claims data (e.g., procedures, admissions, diagnoses, durable medical equipment, nursing homes, etc.), prescription drug data, laboratory data, clinical data, and patient reported data. Additionally, the outputs from our analytical processes translate into patient-specific questions and guidance within the ePASS® toolset availing the clinician to potential concerns around disease, quality, utilization, medication adherence, preventative medicine, patient education, and many other areas of focus. In addition to its core functionality, ePASS® is easily configured to allow custom analytics, question sets, and testing follow-up to be incorporated for specific needs. ePASS® patient-specific, point-of-care documentation and decision support capabilities generates medical record documentation in a regulatory-compliant format to support treatment plans, continuity of care, and patient data accuracy. Ultimately, the use of ePASS® patient data access and decision support capability results in not only a more comprehensive clinical encounter, but a more efficient encounter.

Site Review Support Application (SRSA™). SRSA™ coordinates clinical data collection at facilities across the nation. To achieve this, as a first step, SRSA™ orchestrates the determination of which clinical data medium and transfer modality may be most efficiently achieved (e.g., remote EHR access, EHR data export, fully integrated EHR interoperability, paper-based medical records, etc.). Once data mediums are determined, SRSA™ undertakes necessary steps of facility communications, onsite scheduling, data abstraction, review, and quality control. During the fourth quarter of 2014, Inovalon launched the next generation of SRSA™, known as SAFHIRE™. This next generation of SRSA™ advances our ability to aggregate, quality control, and process clinical data more efficiently and on greater scale than ever before, enhancing the ability to interact with clinical facilities more effectively and load balance workflows across Inovalon's nationwide presence.

Integrated Data Collection Tool (iDCT™). The iDCT™ facilitates the accurate and efficient recordation of clinical information into discrete data elements from a wide variety of clinical data sources. The iDCT™ incorporates both hard and soft error correction and quality control capabilities supporting the comprehensive data review and audit trail development process. Deployed in both cloud-based configurations and through an "occasionally connected" mobile configuration, the iDCT™ allows for clinical data abstraction in large volumes.

Integrated Telephonic Communication Coordinator (iTCC™). In order to achieve effective provider and patient engagement, outbound and inbound communications must be highly targeted based upon analytics and informed with integrated patient and provider profiles to make communications effective and efficient. iTCC™ supports this communication to ensure that value is delivered and program goals are achieved for clients. The iTCC™ manages the communications and logistics of the following value delivery modalities:

Claims Aggregation, Analysis and Submissions system, or CAAS™. CAAS™ provides comprehensive claims data warehousing and processing to support government-mandated data submissions and cost reporting. It supports the integration of data in the raw, native format with strong data quality oversight to ensure ETL data accuracy. As a component of regulatory compliance, the CAAS™ system manages the formulation of de-identified patient-level datasets and provides a solution to manage and respond in a timely manner to rejected, edited records/reports from HHS.

CAAS™ serves as a staging warehouse and processing system where all pertinent submission data is stored, and on which analytics are run to identify the data appropriate for submission including:

INDICES™. Our INDICES™ toolset is an enterprise-level, web- enabled business intelligence reporting toolset that provides visualization of data and results to authorize client users via dashboards, reports, and ad hoc queries. INDICES™ is built on online analytical processes (OLAP) technologies to integrate our clients' data (e.g., patient, enrollment, lab results, pharmacy, claims, etc.), the results from our data analytics and data-driven interventions, and benchmark information from our MORE² Registry®, to provide our clients with the ability to gain insight into the multiple facets of their patients, providers, and facility network. INDICES™ supports our clients' goals to improve the quality of care provided to patients, drive financial performance, and aid in the support of their strategic business and care decisions.

In addition to enabling real-time insight into common considerations such as utilization, member demographics, and financial performance across populations and customized cohorts, the INDICES™ toolset also provides valuable business intelligence into the analysis of highly complex and valuable considerations in healthcare. For example, INDICES™ can provide users patient- level risk

sub-segmented by plan-defined characteristics; population, cohort, and patient-level premium revenue and risk-adjusted revenue sub- segmented by plan-defined characteristics; population, cohort, and patient- level reinsurance accumulation sub-segmented by plan-defined characteristics; population, cohort, and patient-level medical loss ratios sub-segmented by plan-defined characteristics; and population, cohort, and patient-level Edge Server processing analysis and results reconciliation. Further, INDICES™ provides insight into highly sophisticated analytics such as quality outcome score projections for future reporting periods which necessarily take into consideration the impact of national score projections on individual Star rating thresholds as set by CMS.

For over 16 years, we have provided quality services to our clients. During that time, we have built a leading position and have become a true thought leader and innovator in our industry. We have achieved significant scale, and we believe that we play a key role in the U.S. healthcare market. During 2015, we provided services to hundreds of clients of various sizes in markets around the country, representing 20 of the top 25 health plans by size, 117 of 456 U.S. health plans, 105 of 733 ACOs, and 176 of 1,665 life sciences organizations. For the year ended December 31, 2014, two significant clients, Independence Blue Cross and Anthem (formerly known as WellPoint), each expanded their business with us to account for between 11% and 12%, respectively, of our total revenue during the year. For the year ended December 31, 2015, each of the aforementioned significant clients remained significant clients of ours, however, as our Company grew, Independence Blue Cross no longer represented greater than 10% of our revenue. For the year ended December 31, 2015, Anthem accounted for approximately 12% of our total revenue, while no other clients represented greater than 10% of our revenue. See Note 2 (Summary of Significant Accounting Policies), under the heading "Concentrations of Credit Risk", included elsewhere within this annual report on Form 10-K for more information.

Because our analytics and data-driven intervention services speak to a complex set of industry pressures, we have chosen to structure our client services organization around associates with industry-leading subject matter expertise. This approach affords our clients the opportunity to leverage their client services support as consultative partners, providing greater opportunity to maximize the value clients receive from our platforms. By interacting with our clients in this manner, we are able to leverage our associate industry- specific knowledge to better anticipate client needs and identify opportunities for our clients in the markets they serve. We believe our clients highly value this differentiated approach and, along with it, the industry, technological, and product expertise our associates possess.

Client services support teams are assigned to our clients, and receive support from client service general managers and their teams of subject matter experts. The client service general managers are responsible for the end- to-end delivery of our solutions and contractual commitments.

We believe that our sales and marketing initiatives are key to capitalizing on our significant market and growth opportunities. While we have successfully leveraged our sales and marketing as we have grown, we believe that additional strategic investments in sales and marketing will enable us to increasingly seize on the healthcare industry's need for data analytics and data-driven intervention services.

Our marketing and communications strategies are centered on initiatives that drive awareness of our company and capabilities. These initiatives include: educating the market about our company broadly; hosting speaking engagements; disseminating articles discussing data trends and metrics, and strategic interfacing with key business and trade media personnel. We employ a broad array of specific events to facilitate these initiatives, including but not limited to:

In addition, in order to enhance our value proposition, our sales and marketing staff develop best practices tools, case studies, and educational materials to drive deeper client utilization and engagement.

Our operations are divided into two groups. Our IT operations group manages the process steps from data receipt through to the generation of analytical outputs. Our services operations group manages the process steps applied to achieve impact through our data-driven intervention platforms.

We achieve excellence in the operation of our technology based on a foundation of service management aligned with data integration, data provisioning, system support, and security operations. These operational processes are measured clearly through a framework of key performance indicators, which seek to provide an optimal level of transparency and control.

We have implemented a rigorous command and control structure for maintaining availability of production systems and ensuring the security of technology infrastructure. Our NOC is responsible for monitoring network and systems, security incident response, and management and communication as well as the oversight of planned system maintenance. The personnel of the NOC are also responsible for invoking our business continuity plan when appropriate.

The security operations within our NOC maintains the confidentiality, integrity, and availability of our production systems and technology infrastructure by maintaining security situational awareness, as well as coordinating security incident response and proactively protecting sensitive data. The security operations team utilizes a variety of tools and techniques to identify, contain, remediate, and gather intelligence on both known and emerging technology threats. Reports are tracked through automated event management triggers and communicated to leadership through our business service management layer.

We have a comprehensive framework for managing change control, problem management, incident and event management, service management, and production operations. We use a defined quality change control management system for managing technology changes.

Product support integration across all of our solutions enables commonality of processes—allowing our clients to benefit from increased technology operational efficiencies. Regardless of the efficiencies achieved, we are continuously enhancing our technology product operations through the dedication of the process automation and performance assurance team focused on designing and deploying zero-touch capabilities.

Many of our clients utilize the analytical outputs of our platform to feed into their own internal systems to achieve value within the provider and patient base. Other clients license our data-driven intervention platforms to facilitate the realization of value from our analytics. For still other clients, our service support personnel operate our data-driven intervention platforms to deliver end-to-end value realization. For these clients, through the implementation of our sophisticated platforms, we leverage our analytical output to provide data-driven intervention support services at the varying points of care necessary to achieve the goals of our clients. This unique end- to-end approach implements the solutions necessary to turn insight into meaningful impact and realized value on a national scale.

One of the centerpieces of our services operations is our strong management systems which serve as vehicles to drive transparency, ownership and execution. We enable our management systems to allow general managers and operational leaders the ability to "see around the corner," and be ambidextrous in how they balance achieving efficiency gains while also focusing on exceptional client value delivery.

We compete with a broad and diverse set of businesses. We believe the competitive landscape is highly fragmented with no single competitor offering similarly expansive capabilities and solution offerings in healthcare data analytics and data-driven interventions. Our primary competitive challenge is to demonstrate to our existing and potential clients the value of utilizing our platforms rather than developing or assembling their own alternative capabilities. However, we believe that the combination of our competitive strengths and successful culture of innovation, including our industry-leading analytics and data asset, the time-tested and real-world-tested nature of our platforms, and subject-matter expertise of our associates, make it time and cost prohibitive for our clients to replace or replicate all that we offer without facing material risk.

The competitive landscape can be characterized by the following categories of companies that provide capabilities or solutions that compete with one or more components of our platforms:

We rely on copyright, trademark, and trade secret laws as well as confidentiality agreements, licenses, and other agreements with employees, consultants, vendors, and customers. We also seek to control access to and distribution of our proprietary software, confidential information and know- how, technology, and other intellectual property. Historically, because our initial technological innovations were primarily algorithmic in nature, these innovations were well suited to trade secret protection. Accordingly, and due to the complex, time intensive, and costly patent process, with somewhat limited utility for business processes, the use of patents has not historically been compelling for us. However, beginning in the second quarter of 2015, we filed a limited number of provisional and non-provisional patent applications, which may or may not result in an issued patent or patents, and expect to continue to seek patents in the future.

We own and use trademarks in connection with our applications and services, including both unregistered common law marks and issued trademark registrations in the United States. Our material trademarks, service marks and other marks include: CAAS^TM, CARA®, Caresync Advantage®, CCS Advantage®, CEDI^TM, ChaseWise^TM, Circle Logo®, Data-Driven Improvements in Health Care^TM, Distributed Analytics®, EMR Acceleration^TM, eCAAS Advantage®, ePASS®, Healthcare Empowered®, Healthier Members, Healthier Business®, HEDIS Advantage, HCC Surveillance®, HIX Foundation®, iDCT^TM, INDICES^TM, Inovalon, Inovalon—US, Inovalon—EU, Inovalon Healthcare Empowered (and Spiral Design to left)—EU, Inovalon (and Spiral Design on top), Inovalon (and Spiral Design to left), Inovalon Healthcare Empowered (and Spiral Design on top), Inovalon Healthcare Empowered (and Spiral Design to left)—US, Inovalon Healthcare Empowered (wordmark), Insights: a business intelligence solution, iPORT^TM, iTCC^TM, MORE² Registry®, PCIS™, Prospective Advantage®, QSCL, QSFD®, QSI®, SRSA^TM, Star Advantage®, Turning Data into Insight and Insight into Action®, We See Solutions^TM, Data Diagnostics^TM and DDx^TM. We also have trademark applications pending to register marks in the United States and European Union.

As of December 31, 2015, we had a total of 3,323 associates across four areas: Technology, Innovation and Product, Data-driven Client Services, and Selling, General and Administrative. There were 2,019 full-time associates and 1,304 part-time associates. None of our associates are represented by a labor union, and all of our associates currently work in the U.S. and its territories (Puerto Rico), and we consider our current relations with our associates to be good.

HIPAA and Other Privacy and Security Requirements. There are numerous U.S. federal and state laws and regulations related to the privacy and security of personal information. In particular, regulations promulgated pursuant to HIPAA establish privacy and security standards that limit the use and disclosure of PHI and require the implementation of administrative, physical, and technical safeguards to ensure the confidentiality, integrity, and availability of individually identifiable health information in electronic form. Our health plan customers, as well as healthcare clearinghouses and certain providers with which we may have or may establish business relationships, are covered entities that are regulated under HIPAA. HITECH and the Omnibus Final Rule significantly expanded HIPAA's privacy and security requirements. Among other things, HITECH and the Omnibus Final Rule make HIPAA's privacy and security standards directly applicable to "business associates," which are independent contractors or agents of covered entities that create, receive, maintain, or transmit PHI in connection with providing a service for or on behalf of a covered entity. Under HIPAA and our contractual agreements with our customers, we are considered a "business associate" to our customers and thus are directly subject to HIPAA's privacy and security standards. In order to provide our covered entity clients with services that involve the use or disclosure of PHI, HIPAA requires our clients to

enter into business associate agreements with our clients. Such agreements must, among other things, require us to:

In addition to HIPAA, HITECH, and their implementing regulations, we may be subject to other state and federal privacy laws, including laws that prohibit unfair privacy and security practices and deceptive statements about privacy and security and laws that place specific requirements on certain types of activities, such as data security and texting. We may also be subject to state medical record privacy laws, which may be more strict than HIPAA, including the laws of the state of California.

Data Protection and Breaches. In recent years, there have been a number of well-publicized data breaches involving the improper use and disclosure of individuals' personal information. Many states have responded to these incidents by enacting laws requiring holders of personal information to maintain safeguards and to take certain actions in response to a data breach, such as providing prompt notification of the breach to affected individuals and state officials. In addition, under HIPAA and pursuant to our business associate agreement obligations, we must report breaches of unsecured PHI to our contractual partners following discovery of the breach. Notification must also be made in certain circumstances to affected individuals HHS and the media.

We have implemented and maintain physical, technical, and administrative safeguards intended to protect individually identifiable health information and have processes in place to assist us in complying with all applicable laws, regulations, and contractual requirements regarding the protection of these data and properly responding to any security breaches or incidents. Furthermore, in many cases, applicable state laws, including breach notification requirements, are not preempted by the HIPAA privacy and security standards and are subject to interpretation by various courts and other governmental authorities, thereby complicating our compliance efforts. Where a state law is not preempted by HIPAA, we may also be subject to that state law's requirements, in addition to our obligations under HIPAA, HITECH, and their implementing regulations. Additionally, state and federal laws regarding deceptive practices may apply to public assurances we give to individuals about the security of services we provide on behalf of our contractual customers.

Other Requirements. In addition to HIPAA, numerous other U.S. state and federal laws govern the collection, dissemination, use, access to, and confidentiality of individually identifiable health information and healthcare provider information. Some states also are considering new laws and regulations that further protect the confidentiality, privacy, and security of medical records or other types of medical information. Further, Congress and a number of states have considered or are considering prohibitions or limitations on the disclosure of medical or other information to individuals or entities located outside of the United States.

The nature of our customers' end-market results in seasonality reflected in both revenue and cost of revenue differences during the year. Regulatory impact of data submission deadlines in, for example, March, June, September, and January drive predictable timing of analytics and data processing activity

variances from quarter to quarter. Further, regulatory clinical encounter deadlines of June 30th and December 31st drive predictable intervention concentrations variances from quarter to quarter. The timing of these factors results in analytical and intervention activity mix variances which predictably impact financial performance from quarter to quarter. The trend of higher client focus on "watchful waiting" has increasingly shifted intervention platform usage to later in the year.

Please refer to the section entitled "Special Note Regarding Forward-Looking Statements" at the beginning of this Annual Report on Form 10-K.

We may not grow at the rates we historically have achieved or at all, even if our key metrics may indicate growth, which could have a material adverse effect on the market price of our Class A common stock.

We have experienced significant growth since 2011, with total revenues growing from approximately $239.7 million for the year ended December 31, 2011 to approximately $437.3 million for the year ended December 31, 2015. Future revenues may not grow at these same rates or may decline, such as the approximate 1% revenue decline from the year ended December 31, 2012 to the year ended December 31, 2013. Our future growth will depend, in part, on our ability to grow our revenue from existing clients, to complete sales to potential future clients, to expand our client base in the life sciences industry and with provider organizations and employer and private exchanges, to develop direct-to-consumer services and to expand internationally. We can provide no assurances that we will be successful in executing on these growth strategies or that, even if our key metrics, such as trailing 12 month Patient Analytics Months ("PAM"), would indicate future growth, we will continue to grow our revenue or net income. Our ability to execute on our existing sales pipeline, create additional sales pipelines, and expand our client base depends on, among other things, the attractiveness of our services relative to those offered by our competitors, our ability to demonstrate the value of our existing and future services, and our ability to attract and retain a sufficient number of qualified sales and marketing leadership and support personnel. In addition, clients in certain industries in which we have a more limited presence, such as the life sciences industry, may be slower to adopt our services than we currently anticipate, which could adversely affect our results of operations and growth prospects.

If our existing clients do not renew their agreements with us, renew at lower fee levels, decline to purchase additional services from us, choose to purchase fewer services from us, or terminate their agreement with us, and we are unable to replace any lost revenue, our business and operating results could suffer.

We historically have derived, and expect in the future to derive, a significant portion of our revenue from renewals of existing client agreements and sales of additional services to existing clients. As a result, achieving a high renewal rate of our client agreements and selling additional services to existing clients is critical to our future operating results. It is difficult to predict our client renewal rate, and we may experience significantly more difficulty than we anticipate in renewing existing client agreements. Factors that may affect the renewal rate for our services and our ability to sell additional services include:

Contracts with our clients generally have stated terms of two to four years. Our clients have no obligation to renew their contracts for our services after the term expires. In addition, our clients may negotiate terms less advantageous to us upon renewal, may renew for fewer services, may choose to

discontinue one or more services under an existing contract, may exercise flexibilities within their contracts to adjust service volumes, or which could reduce our revenue from these clients, which, for example, occurred during the second quarter of 2013. Our future operating results also depend, in part, on our ability to sell new services to our existing clients. If our clients fail to renew their agreements, renew their agreements upon less favorable terms, at lower fee levels or for fewer services, fail to purchase new services from us, or terminate their agreements with us, and we are unsuccessful in generating significant revenue from new clients to replace any lost revenue, our revenues may decline and our future revenue growth may be constrained.

If a client fails to fulfill its obligations under its agreements with us, or permanently terminates certain services or its agreement in its entirety prior to its expected completion date, whether or not in our view permitted by the terms of the agreement, and revenue and cash flows expected from a client are not realized in the time period expected or at all, our business, operating results and financial condition could be adversely affected.

Our top clients account for a significant portion of our revenues and, as a result, the loss of one or more of these clients could materially and adversely affect our business and operating results.

Our largest client, Anthem (formerly known as WellPoint), represented approximately 12% of our revenues for the year ended December 31, 2015, while no other clients represented greater than 10% of our revenue. Moreover, our top ten clients accounted for approximately 68% of our revenues for the year ended December 31, 2015. The engagement between these clients and us generally is covered through multiple separate statements of work ("SOWs"), each often with different and/or staggered terms which are all multi-year in their duration, ranging typically from two to four years. We can provide no assurance that these clients will renew their existing contracts or all SOWs with us upon expiration or that any such failure to renew will not have a material adverse effect on our revenue. For example, our revenue for the year ended December 31, 2013 decreased by approximately 1% as compared to the year ended December 31, 2012, in part as a result of a client's decision to discontinue several integrated solution engagements during the second quarter of 2013. If we lose one or more of our top clients, or if one or more of these clients significantly decreases its use of our services, our business and operating results could be materially and adversely affected.

If we do not develop new services that are adopted by clients, or fail to provide high quality support services to our clients, our growth prospects, revenues and operating results could be materially and adversely affected.

Our longer-term operating results and revenue growth will depend in part on our ability to successfully develop and sell new services that existing and potential clients want and are willing to purchase. We must continue to invest significant resources in research and development in order to enhance our existing services and introduce new high-quality services that clients and prospective clients will want. If we are unable to predict or adapt to changes in user preferences or industry or regulatory changes, or if we are unable to modify our services on a timely basis in response to those changes, clients may not renew their agreements with us, and our services may become less attractive than services offered by our competitors. Our operating results could also suffer if our innovations are not responsive to the needs of our clients, are not appropriately timed with market opportunity, or are not effectively brought to market. Our success also depends on successfully providing high-quality support services to resolve any issues related to our services. High-quality education and client support is important for the successful marketing and sale of our services and for the renewal of existing clients. If we do not help our clients quickly resolve issues and provide effective ongoing support, our ability to sell additional services to existing clients would suffer and our reputation with existing or potential clients would be harmed.

We cannot assure you that we will be able to manage our growth effectively, which could have a material adverse effect on our business, results of operations and growth prospects.

If we are successful in expanding our client base and growing our business, our existing services may not be as scalable as we anticipate, and we may need to expend significant resources to enhance our IT infrastructure, financial and accounting systems, and controls, and also hire a significant number of qualified client support personnel, professional services personnel, software engineers, technical personnel, and management personnel in order to provide services to those new clients. As a result, our expenses may increase more than expected, which could adversely affect our results of operations. In addition, identifying and recruiting qualified personnel and training them in the use of our services requires significant time, expense, and attention, and our business may be adversely affected if our efforts to expand and train qualified personnel do not generate a corresponding increase in revenues. If our existing services are not as scalable as we anticipate or if we are unable to manage our growth effectively, the quality of our services and our reputation may suffer, which could adversely affect our business, results of operations and growth prospects.

If our security measures fail or are breached and unauthorized access to a client's data is obtained, our services may be perceived as insecure, we may incur significant liabilities, our reputation may be harmed, and we could lose sales and clients.

Our services involve the storage and transmission of clients' proprietary information, sensitive or confidential data, including valuable intellectual property and personal information of employees, clients and others, as well as protected health information, or PHI, of our clients' patients. Because of the extreme sensitivity of the information we store and transmit, the security features of our computer, network, and communications systems infrastructure are critical to the success of our business. A breach or failure of our security measures could result from a variety of circumstances and events, including third-party action, employee negligence or error, malfeasance, computer viruses, cyber-attacks by computer hackers, failures during the process of upgrading or replacing software and databases, power outages, hardware failures, telecommunication failures, user errors, or catastrophic events. Information security risks have generally increased in recent years because of the proliferation of new technologies and the increased sophistication and activities of perpetrators of cyber-attacks. As cyber threats continue to evolve, we may be required to expend additional resources to continue to enhance our information security measures or to investigate and remediate any information security vulnerabilities. If our security measures fail or are breached, it could result in unauthorized persons accessing sensitive client or patient data (including PHI), a loss of or damage to our data, an inability to access data sources, or process data or provide our services to our clients. Such failures or breaches of our security measures, or our inability to effectively resolve such failures or breaches in a timely manner, could severely damage our reputation, adversely affect client or investor confidence in us, and reduce the demand for our services from existing and potential clients. In addition, we could face litigation, damages for contract breach, monetary penalties, or regulatory actions for violation of applicable laws or regulations, and incur significant costs for remedial measures to prevent future occurrences and mitigate past violations. Although we maintain insurance covering certain security and privacy damages and claim expenses, we may not carry insurance or maintain coverage sufficient to compensate for all liability and in any event, insurance coverage would not address the reputational damage that could result from a security incident.

We may experience cyber-security and other breach incidents that may remain undetected for an extended period. Because techniques used to obtain unauthorized access or to sabotage systems change frequently and generally are not recognized until launched, we may be unable to anticipate these techniques or to implement adequate preventive measures. In addition, in the event that our clients authorize or enable third parties to access their information and data that are stored on our systems, we cannot ensure the complete integrity or security of such data in our systems as we would not control

access. If an actual or perceived breach of our security occurs, or if we are unable to effectively resolve such breaches in a timely manner, the market perception of the effectiveness of our security measures could be harmed and we could lose sales and clients, which could have a material adverse effect on our business, operations, and financial results.

Data protection, privacy and similar laws restrict access, use, and disclosure of information, and failure to comply with or adapt to changes in these laws could materially and adversely harm our business.

We are subject to data privacy and security regulation by both the federal government and the states in which we conduct our business. The Health Insurance Portability and Accountability Act of 1996, and its implementing regulations, which we refer to collectively as HIPAA, established uniform federal standards for certain "covered entities," which include healthcare providers and health plans, governing the conduct of specified electronic healthcare transactions and protecting the security and privacy of PHI. The Health Information Technology for Economic and Clinical Health Act, or HITECH, which became effective on February 17, 2010, and an implementing regulation known as the Omnibus Final Rule, which became effective on September 23, 2013, make HIPAA's privacy and security standards directly applicable to "business associates," which are independent contractors or agents of covered entities that create, receive, maintain, or transmit PHI in connection with providing a service for or on behalf of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities, business associates, and other persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce HIPAA's requirements and seek attorney's fees and costs associated with pursuing federal civil actions.

A portion of the data that we obtain and handle for or on behalf of our clients is considered PHI and subject to HIPAA because our clients are covered entities under HIPAA and we act as their business associate. Under HIPAA and our contractual agreements with our HIPAA-covered entity health plan clients, we are considered a "business associate" to those clients, and are required to maintain the privacy and security of PHI in accordance with HIPAA and the terms of our agreements with clients, including by implementing HIPAA-required administrative, technical, and physical safeguards. We have incurred, and will continue to incur, significant costs to establish and maintain these safeguards and, if additional safeguards are required to comply with HIPAA or our clients' requirements, our costs could increase further, which would negatively affect our operating results. Furthermore, if we fail to maintain adequate safeguards, or we use or disclose PHI in a manner not permitted by HIPAA or our agreements with our clients, or if the privacy or security of PHI that we obtain and handle is otherwise compromised, we could be subject to significant liabilities and consequences, including, without limitation:

Laws and expectations relating to privacy continue to evolve, and we continue to adapt to changing needs. Nevertheless, changes in these laws may limit our data access, use, and disclosure, and may

require increased expenditures by us or may dictate that we not offer certain types of services. Any of the foregoing may have a material adverse effect on our ability to provide services to our clients and, in turn, our results of operations.

Data protection, privacy and similar laws protect more than patient information and, although they vary by jurisdiction, these laws can extend to employee information, business contact information, provider information, and other information relating to identifiable individuals. Failure to comply with these laws may result in, among other things, civil and criminal liability, negative publicity, damage to our reputation, and liability under contractual provisions. In addition, compliance with such laws may require increased costs to us or may dictate that we not offer certain types of services in the future.

The information that we provide to our clients could be inaccurate or incomplete, which could harm our business reputation, financial condition, and results of operations.

We aggregate, process, and analyze healthcare-related data and information for use by our clients. Because data in the healthcare industry is fragmented in origin, inconsistent in format, and often incomplete, the overall quality of data received or accessed in the healthcare industry is often poor, the degree or amount of data which is knowingly or unknowingly absent or omitted can be material, and we frequently discover data issues and errors during our data integrity checks. If the analytical data that we provide to our clients are based on incorrect or incomplete data or if we make mistakes in the capture, input, or analysis of these data, our reputation may suffer and our ability to attract and retain clients may be materially harmed.

In addition, we assist our clients with the management and submission of data to governmental entities, including CMS. These processes and submissions are governed by complex data processing and validation policies and regulations. If we fail to abide by such policies or submit incorrect or incomplete data, we may be exposed to liability to a client, court, or government agency that concludes that our storage, handling, submission, delivery, or display of health information or other data was wrongful or erroneous. Although we maintain insurance coverage, this coverage may prove to be inadequate or could cease to be available to us on acceptable terms, if at all. Even unsuccessful claims could result in substantial costs and diversion of management time, attention, and resources. A claim brought against us that is uninsured or under-insured could harm our business, financial condition, and results of operations.

General economic, political and market forces and dislocations beyond our control could reduce demand for our solutions and harm our business.

The demand for our platforms, toolsets and services may be impacted by factors that are beyond our control, including macroeconomic, political and market conditions, the availability of short-term and long-term funding and capital, and the level of interest rates. The U.S. economy has begun to show signs of slowing, and global securities markets have become increasingly volatile. Any one or more of these factors may contribute to reduced demand for our platforms, toolsets and services, which could have an adverse effect on our results of operations and financial condition.

Our business is principally focused on the healthcare industry, and factors that adversely affect the financial condition of the healthcare industry could consequently affect our business.

We derive substantially all of our revenue from clients within the healthcare industry. As a result, our financial condition and results of operations could be adversely affected by conditions affecting the healthcare industry generally and health systems and payors in particular. For example, consumer operated and oriented plans, or health insurance CO-Ops, have recently experienced financial distress, including insolvency, bankruptcy or liquidation, and have been forced to exit the exchange marketplace. Our ability to grow will depend upon the economic environment of the healthcare industry, as well as

our ability to increase the number of services that we sell to our clients. Furthermore, we may not become aware in a timely manner of changes in regulatory requirements affecting our business, which could result in us taking, or failing to take, actions, resulting in noncompliance with state or federal regulations.

There are many factors that could affect the purchasing practices, operations and, ultimately, the operating funds of healthcare organizations, such as reimbursement policies for healthcare expenses, consolidation in the healthcare industry, and regulation, litigation, and general economic conditions. In particular, we could be required to make unplanned modifications to our services or could suffer delays or cancellations of orders or reductions in demand for our services as a result of changes in regulations affecting the healthcare industry, such as any increased regulation by governmental agencies, changes to HIPAA and other federal or state privacy laws, laws relating to the tax- exempt status of many of our clients or restrictions on permissible discounts, and other financial arrangements. It is unclear what long-term effects the general economic conditions will have on the healthcare industry, and in turn, on our business, financial condition, and results of operations.

Consolidation in the industries in which our clients operate may result in certain clients discontinuing their use of our services following an acquisition or merger, which could materially and adversely affect our business and financial results.

Mergers or consolidations among our clients have in the past and could in the future reduce the number of our existing and potential clients. When companies consolidate, overlapping services previously purchased separately are typically purchased only once by the combined entity, leading to loss of revenue for the service provider. If our clients merge with or are acquired by other entities that are not our clients, they may discontinue their use of our services. There can be no assurance as to the degree to which we may be able to address the revenue impact of such consolidation. Any of these developments could materially and adversely affect our business and financial results.

Our services could become subject to new, revised, or enhanced regulatory requirements in the future, which could result in increased costs, could delay or prevent our introduction of new services, or could impair the function or value of our existing services, which could materially and adversely affect our results of operations and growth prospects.

The healthcare industry is highly regulated on the federal, state, and local levels, and is subject to changing legislative, regulatory, political, and other influences. Changes to existing laws and regulations, or the enactment of new federal and state laws and regulations affecting the healthcare industry, could create unexpected liabilities for us, could cause us or our clients to incur additional costs, and could restrict our or our clients' operations.

Many healthcare laws are complex, subject to frequent change, and dependent on interpretation and enforcement decisions from government agencies with broad discretion. The application of these laws to us, our clients, or the specific services and relationships we have with our clients is not always clear. In addition, federal and state legislatures have periodically considered programs to reform or amend the U.S. healthcare system at both the federal and state level, such as the enactment of the Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010, or the Affordable Care Act or ACA. The ACA included provisions to control health care costs, improve health care quality, and expand access to affordable health insurance. Together with ongoing statutory and budgetary policy developments at a federal level, this health care reform legislation could include changes in Medicare and Medicaid payment policies and other health care delivery administrative reforms that could potentially negatively impact the business of our clients. Because not all the administrative rules implementing health care reform under the legislation have been finalized, because of ongoing federal fiscal budgetary pressures yet to be resolved for federal health programs, and because of the lack of implementing regulations or interpretive guidance, gradual and partially

delayed implementation, possible amendment, repeal or further implementation delays, the full impact of the health care reform legislation and of further statutory actions to reform healthcare payment on our business and the business of our clients is unknown. There can be no assurances that health care reform legislation will not adversely impact either our operational results or the manner in which we operate our business. Health care industry participants may respond by reducing their investments or postponing investment decisions, including investments in our platforms, solutions and services. Our failure to anticipate accurately the application of these laws and similar or future laws and regulations, or our failure to comply with them, could create liability for us, result in adverse publicity, and negatively affect our business.

Our services may become subject to new or enhanced regulatory requirements, and we may be required to change or adapt our services in order to comply with these regulations. For example, the introduction of the new ICD-10 coding framework in 2015, pursuant to which physicians are expected to characterize the specific conditions of patients among more than 90,000 discrete descriptions (up from nearly 15,000 discrete descriptions under the existing ICD-9 framework), could present additional challenges for our business, including requiring us to allocate resources to training and upgrading our systems. If we fail to successfully implement the new ICD-10 coding framework, it could adversely affect our ability to offer services deemed critical by our clients, which could materially and adversely affect our results of operations. New or enhanced regulatory requirements may render our services obsolete or prevent us from performing certain services. New or enhanced regulatory requirements could impose additional costs on us, and thereby make existing services unprofitable, and could make the introduction of new services more costly or time-consuming than we anticipate, which could materially and adversely affect our results of operations and growth prospects.

Because personal, public, and non-public information is stored in some of our databases, we are vulnerable to government regulation and adverse publicity concerning the use of our data. We provide many types of data and services that already are subject to regulation under HIPAA and, to a lesser extent, various other federal, state, and local laws and regulations. These laws and regulations are designed to protect the privacy of the public and to prevent the misuse of personal information in the marketplace. However, many consumer advocates, privacy advocates, and government regulators believe that the existing laws and regulations do not adequately protect privacy. They have become increasingly concerned with the use of personal information, including health information. As a result, they are lobbying for further restrictions on the dissemination or commercial use of personal information to the public and private sectors. Similar initiatives are under way in other countries in which we may do business in the future. The following legal and regulatory developments also could have a material adverse effect on our business, financial position, results of operations, or cash flows:

Our estimates of market opportunity and forecasts of market growth may prove to be inaccurate, and even if the market in which we compete achieves the forecasted growth, our business could fail to grow at similar rates, if at all.

Market opportunity estimates and growth forecasts are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. Our estimates and forecasts

relating to the size and expected growth of our aggregate market opportunity or any of the sub-components of our total addressable market may prove to be inaccurate. Even if our total addressable market or any sub-component thereof meets our size estimates and forecasted growth, our business could fail to grow at similar rates, if at all.

Our proprietary applications may not operate properly, which could damage our reputation, give rise to a variety of claims against us, or divert our resources from other purposes, any of which could harm our business and operating results.

Proprietary software and application development is time-consuming, expensive, and complex, and may involve unforeseen difficulties. We may encounter technical obstacles, and it is possible that we discover additional problems that prevent our proprietary applications from operating properly. If our applications and services do not function reliably or fail to achieve client expectations in terms of performance, clients could assert liability claims against us and attempt to cancel their contracts with us. Moreover, material performance problems, defects, or errors in our existing or new applications and services may arise in the future and may result from, among other things, the lack of interoperability of our applications with systems and data that we did not develop and the function of which is outside of our control or undetected in our testing. Defects or errors in our applications might discourage existing or potential clients from purchasing services from us. Correction of defects or errors could prove to be time consuming, costly, impossible, or impracticable. The existence of errors or defects in our applications and the correction of such errors could divert our resources from other matters relating to our business, damage our reputation, increase our costs, and have a material adverse effect on our business, financial condition, and results of operations.

As a result of our variable sales and implementation cycles, we might not be able to recognize revenue to offset expenditures, which could result in fluctuations in our quarterly results of operations or otherwise adversely affect our future operating results.

The sales cycle for our services is typically four to six months from initial contact to contract execution, but can vary depending on the particular client, product under consideration, and time of year, among other factors. Some clients, for instance, undertake a more prolonged evaluation process, which has in the past resulted in extended sales cycles. Our sales efforts involve educating potential clients about the use, technical capabilities, and benefits of our services, and gaining an understanding of their needs and budgets. During the sales cycle, we expend significant time and resources, and we do not recognize any revenue to offset such expenditures, which could result in fluctuations in our quarterly results of operations and adversely affect our future operating results.

After a client contract is signed, we provide an implementation process for the client during which we load, test, and integrate data into our system and train client personnel. Our implementation cycle generally ranges from 20 to 90 days from contract execution to completion of implementation, but can vary depending on the amount and quality of the client's data and how quickly the client facilitates access to data. In addition, for certain clients, our third-party vendors must go through delegation processes in order to become authorized to provide certain services to those clients, which could delay our ability to provide such services to those clients. During the implementation cycle, we expend time, effort, and financial resources implementing our services, but accounting principles do not allow us to recognize the resulting revenue until implementation is complete and the services are available for use by our clients. If implementation periods are extended, revenue recognition will be delayed, which could adversely affect our results of operations in certain periods.

In addition, because most of our revenue in each quarter is derived from agreements entered into with our clients during previous quarters, the negative impacts resulting from a decline in new or renewed agreements in any one quarter may not be fully reflected in our revenue for that quarter. Such declines, however, would negatively affect our revenue in future periods and the effect of significant

downturns in sales of and market demand for our services, and potential changes in our renewal rates or renewal terms may not be fully reflected in our results of operations until future periods. Our sales and implementation cycles also make it difficult for us to rapidly increase our total revenue through additional sales in any period. As a result, the effect of changes in the industry impacting our business, or changes we experience in our new sales, may not be reflected in our short-term results of operations.

We operate in a competitive industry, and if we are not able to compete effectively, our business and financial results could be materially and adversely impacted.

We operate in a competitive industry, and we expect that competition will increase as a result of consolidation in both the information technology and healthcare industries. Our future growth and success will depend on our ability to successfully compete with other companies that provide similar services, including existing clients and other healthcare organizations that seek to build and operate competing services themselves and newer companies that provide similar services, often at substantially lower prices. We compete on the basis of various factors, including breadth and depth of services, reputation, reliability, quality, innovation, security, price, and industry expertise, and experience. If we are unable to maintain our technology, management, healthcare, or regulatory expertise or attract and retain a sufficient number of qualified sales and marketing leadership and support personnel, we will be at a competitive disadvantage. Some of our competitors, in particular health plans and larger technology or technology-enabled consultative service providers, have greater name recognition, longer operating histories, and significantly greater resources than we do. Furthermore, our current or potential competitors may have greater financial resources and larger sales and marketing capabilities than we have, and may have a more diversified set of revenue sources, which may allow them to be less sensitive to changes in client preferences and more aggressive in pricing their services, any of which could put us at a competitive disadvantage. As a result, our competitors may be able to respond more quickly and effectively than we can to new or changing opportunities, technologies, standards, or client requirements and may have the ability to initiate or withstand substantial price competition. In addition, potential clients frequently have requested competitive bids from us and our competitors in terms of price and services offered and, if we do not accurately assess potential clients' needs and budgets when submitting our proposals, they may appear less attractive than those of our competitors, and we may not be successful in attracting new business. In addition, our clients may perceive our toolsets to be at a higher price point than our competitors, which could result in reduced revenue if we are not able to adequately demonstrate the value of our toolsets to our clients and prospective clients. Increases in competition in our industry could reduce our market share and result in price declines for certain services, which could negatively impact our business, profitability, and growth prospects.

If we fail to maintain awareness of our brand cost-effectively, our business might suffer.

Maintaining awareness of our brand in a cost-effective manner is critical to continuing the widespread acceptance of our existing services and is an important element in attracting new clients and in attracting and retaining qualified employees. The importance of brand recognition may increase as competition in our market increases. Successful promotion of our brand will depend largely on the effectiveness of our marketing efforts and on our ability to provide reliable and useful services at competitive prices. Our efforts to build and maintain our brand nationally have involved and will continue to involve significant expense. Brand promotion activities may not yield increased revenue, and even if they do, any increased revenue may not offset the expenses we incur in maintaining our brand. In addition, third parties' use of trademarks or branding similar to ours could materially harm our business or result in litigation and other costs. If we fail to successfully maintain our brand, or incur substantial expenses in an unsuccessful attempt to maintain our brand, we may fail to attract enough new clients or retain our existing clients to the extent necessary to realize a sufficient return on our brand-building efforts, and our business and our ability to attract and retain qualified employees could suffer.

Our success depends on our ability to protect our intellectual property rights.

Our success depends in part on our ability to protect our proprietary software, confidential information and know-how, technology, and other intellectual property and intellectual property rights. We rely generally on copyright, trademark and trade secret laws, confidentiality and invention assignment agreements with employees and third parties, and license and other agreements with consultants, vendors, and clients. There can be no assurance that employees, consultants, vendors, and clients have executed such agreements or have not breached or will not breach their agreements with us, that we will have adequate remedies for any breach, or that our trade secrets will not otherwise become known or independently developed by competitors. Additionally, we monitor our use of open source software to avoid uses that would require us to disclose our proprietary source code or violate applicable open source licenses, but if we engaged in such uses inadvertently, we could be required to take remedial action or release certain of our proprietary source code. These scenarios could materially and adversely affect our business, financial condition, and results of operations. In addition, despite the protections we do place on our intellectual property, a third party could, without authorization, copy or otherwise obtain and use our products or technology, or develop similar technology. In addition, agreement terms that address non-competition are difficult to enforce in many jurisdictions and might not be enforceable in certain cases.

We currently hold no issued patents. We have a limited number of provisional and non-provisional patent applications, which may or may not result in an issued patent or patents. In addition, we do not know whether the examination process will require us to narrow our claims. To the extent that patents are issued from our patent applications, which are not certain, they may be contested, circumvented or invalidated in the future. Moreover, the rights granted under any issued patents may not provide us with proprietary protection or competitive advantages, may be successfully challenged by third parties, and, as with any technology, competitors may be able to develop similar or superior technologies to our own now or in the future.

We currently rely on unpatented proprietary technology. It is possible that others will independently develop the same or similar technology or otherwise obtain access to our unpatented technology. To protect our trade secrets and other proprietary information, we require employees, consultants, advisors, and collaborators to enter into confidentiality agreements. We cannot assure you that these agreements will provide meaningful protection for our trade secrets, know-how, or other proprietary information in the event of any unauthorized use, misappropriation, or disclosure of such trade secrets, know-how, or other proprietary information. Further, the theft or unauthorized use or publication of our trade secrets and other confidential business information could reduce the differentiation of our services and harm our business, the value of our investment in development or business acquisitions could be reduced, and third parties might make claims against us related to losses of their confidential or proprietary information.

We rely on our trademarks, service marks, trade names, and brand names to distinguish our services from the services of our competitors, and have registered or applied to register many of these trademarks. We cannot assure you that our trademark applications will be approved. Third parties may also oppose our trademark applications, or otherwise challenge our use of the trademarks. In the event that our trademarks are successfully challenged, we could be forced to rebrand our services, which could result in loss of brand recognition and could require us to devote resources advertising and marketing new brands. Further, we cannot assure you that competitors will not infringe our trademarks or that we will have adequate resources to enforce our trademarks.

Our ability to obtain, protect, and enforce our intellectual property rights is subject to uncertainty as to the scope of protection, registerability, patentability, validity, and enforceability of our intellectual property rights in each applicable jurisdiction, as well as the risk of general litigation or third-party oppositions.

Existing U.S. federal and state intellectual property laws offer only limited protection. Moreover, if we expand our business into markets outside of the United States, our intellectual property rights may not receive the same degree of protection as they would in the United States because of the differences in foreign trademark and other laws concerning proprietary rights. Governments may adopt regulations, and government agencies or courts may render decisions, requiring compulsory licensing of intellectual property rights. When we seek to enforce our intellectual property rights we may be subject to claims that the intellectual property rights are invalid or unenforceable. Litigation may be necessary in the future to enforce our intellectual property rights and to protect our trade secrets. Litigation brought to protect and enforce our intellectual property rights could be costly, time consuming, and distracting to management and could result in the impairment or loss of portions of our intellectual property rights. Furthermore, our efforts to enforce our intellectual property rights may be met with defenses, counterclaims, and countersuits attacking the validity and enforceability of our intellectual property rights. Our inability to protect our proprietary technology against unauthorized copying or use, as well as any costly litigation or diversion of our management's attention and resources, could delay further sales or the implementation of our solutions, impair the functionality of our solutions, delay introductions of new solutions, result in our substituting inferior or more costly technologies into our solutions, or have a material adverse effect on our business, financial condition, and results of operations.

Laws regulating the corporate practice of medicine could restrict the manner in which we provide our clients certain of our intervention toolsets, and the failure to comply with such laws could subject us to penalties or require that we change the manner in which we provide such toolsets.

Among our intervention toolsets are supplemental patient encounters, or SPEs. While some clients utilize our platform toolsets to conduct their own SPEs directly or through third-parties, some of our clients engage us to utilize our intervention platform toolsets to facilitate SPEs. In such cases, we use third-parties to undertake such SPEs utilizing our intervention platform toolsets or may utilize our own associate to undertake such SPEs. Certain of our SPEs may be considered patient care. Some states have laws that prohibit business entities from practicing medicine, employing providers to practice medicine, exercising control over medical decisions by providers (also known collectively as the corporate practice of medicine). These laws, regulations, and interpretations have, in certain states, been subject to enforcement, as well as judicial and regulatory interpretation, and are subject to change.

In these states, we operate by maintaining long term contracts with affiliated physician groups, which are each owned and operated by physicians and which employ or contract with additional providers to perform the SPEs, If there were a determination that a corporate practice of medicine violation existed or exists, we could be subject to criminal or civil penalties or an injunction for practicing medicine without a license or aiding and abetting the unlicensed practice of medicine. The occurrence of any of such events could have a material adverse effect on our ability to continue to provide our clients with the full array of our intervention toolsets.

Our business exposes us to risks that are inherent in the provision of analytics and toolsets that assist clinical decision-making and relate to patient medical histories and treatment plans. If clients or individuals assert liability claims against us, any ensuing litigation, regardless of outcome, could result in a substantial cost to us, divert management's attention from operations, and decrease market acceptance of our toolsets. We attempt to limit our liability to clients by contract; however, the

limitations of liability set forth in the contracts may not be enforceable or may not otherwise protect us from liability for damages. Additionally, we may be subject to claims that are not explicitly covered by contract. We also maintain general liability coverage; however, this coverage may not continue to be available on acceptable terms, may not be available in sufficient amounts to cover one or more large claims against us, and may include larger self-insured retentions or exclusions for certain products. In addition, the insurer might disclaim coverage as to any future claim. A successful claim not fully covered by our insurance could have a material adverse impact on our liquidity, financial condition, and results of operations.

We could incur substantial costs as a result of any claim of infringement of another party's intellectual property rights.

In recent years, there has been significant litigation in the United States involving patents and other intellectual property rights. Companies in the software and healthcare technology and services industries are increasingly bringing and becoming subject to suits alleging infringement of proprietary rights, particularly patent rights, and our competitors and other third parties may hold patents or have pending patent applications which could be related to our business. These risks have been amplified by the increase in third parties, which we refer to as non-practicing entities, whose primary business is to assert infringement claims or make royalty demands. Moreover, many of our current and potential competitors may dedicate substantially greater resources to protection and enforcement of intellectual property rights, especially patents. It is difficult to proceed with certainty in a rapidly evolving technological environment in which there may be patent applications pending related to our technologies, many of which are confidential when filed.

We may receive in the future notices that claim we or our clients using our services have misappropriated or misused other parties' intellectual property rights, particularly as the number of competitors in our market grows and the functionality of services among competitors overlaps. If we are sued by a third party that claims that our technology infringes its rights, the litigation, whether or not successful, could be extremely costly to defend, divert our management's time, attention, and resources, damage our reputation and brand, and substantially harm our business. We do not currently have a patent portfolio of our own, which may limit the defenses available to us in any such litigation.

In addition, in most instances, we have agreed to indemnify our clients against certain third-party claims, which may include claims that one of our services infringes the intellectual property rights of such third parties. These claims may require us to initiate or defend protracted and costly litigation on behalf of our clients, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of our clients or may be required to obtain licenses for the products they use. If we cannot obtain all necessary licenses on commercially reasonable terms, our customers may be forced to stop using our services. In addition, our business could be adversely affected by any significant disputes between us and our clients as to the applicability or scope of our indemnification obligations to them. The results of any intellectual property litigation to which we might become a party, or for which we are required to provide indemnification, may also require us to do one or more of the following:

If we were to discover that our applications and services violate third-party proprietary rights, there can be no assurance that we would be able to obtain licenses to continue offering those applications and services on commercially reasonable terms, or at all, to redesign our technology to avoid

infringement, or to avoid or settle litigation regarding alleged infringement without substantial expense and damage awards. Any claims against us relating to the infringement of third-party proprietary rights, even if not meritorious, could result in the expenditure of significant financial and managerial resources and in injunctions preventing us from distributing certain products. If we are required to make substantial payments or undertake any of the other actions noted above as a result of any intellectual property infringement claims against us or any obligation to indemnify our clients for such claims, such payments or costs could have a material adverse effect on our business, financial condition, and results of operations.

We depend on our senior management team and other key employees, and the loss of one or more of our executive officers or key employees could materially and adversely affect our business.

Our success depends in large part upon the continued services of our key executive officers, including Dr. Dunleavy. We also rely on our leadership team in the areas of research and development, marketing, services, and general and administrative functions. We can provide no assurances that any of our executive officers or key employees will continue their employment with us. The replacement of one or more of our executive officers or other key employees would likely involve significant time and costs and may significantly delay or prevent the achievement of our business objectives.

We may fail to attract, train, and retain enough qualified employees to support our operations and growth strategy, which could materially and adversely affect our business and growth strategy.

The success of our business and growth strategy depends on our ability to attract, train, and retain qualified employees, particularly technology personnel, subject matter experts, sales and marketing leadership and support personnel, and personnel with healthcare regulatory, clinical, and appropriate management expertise. The market for qualified employees in our industry and in the markets in which we operate is very competitive, and companies that we compete with for experienced personnel may have greater resources than we. In addition, our ability to attract and retain qualified employees depends in part on our ability to maintain awareness of our brand. If we are not successful in our recruiting efforts, or if we are unable to train and retain a sufficient number of qualified employees, our ability to develop and deliver successful technologies and services and grow our business may be materially and adversely affected.

We may acquire other companies or technologies, which could divert our management's attention, result in dilution to our stockholders and otherwise disrupt our operations and adversely affect our operating results.

We have previously and may in the future seek to acquire or invest in businesses, services, or technologies that we believe could complement or expand our services, enhance our technical capabilities, or otherwise offer growth opportunities. For example, on September 1, 2015, we acquired Avalere. The pursuit of potential acquisitions may divert the attention of management and cause us to incur various expenses in identifying, investigating, and pursuing suitable acquisitions, whether or not they are consummated. Acquisitions also could result in dilutive issuances of equity securities or the incurrence of debt, which could adversely affect our operating results and financial condition. In addition, we have limited experience in acquiring other businesses. We may not achieve the anticipated benefits from the acquired business, including from Avalere, due to a number of factors, including:

If an acquired business fails to meet our expectations, our operating results, business, and financial condition may suffer materially.

The integration of newly acquired businesses, including Avalere, will also require a significant amount of time and attention from management. The diversion of management attention away from ongoing operations and key research and development, marketing or sales efforts could adversely affect ongoing operations and business relationships. Moreover, even if we were able to fully integrate a new acquisition's business operations and other assets successfully, there can be no assurance that such integration will result in the realization of the full benefits of synergies, cost savings, innovation and operational efficiencies that may be possible or were anticipated from the acquisition or that these benefits will be achieved within a reasonable period of time. Delays in integrating our acquisitions, which could be caused by factors outside of our control, could adversely affect the intended benefits of the acquisitions to our business, financial results, financial condition and the trading price of our Class A common stock.

In addition, a significant portion of the purchase price of companies we acquire may be allocated to acquired goodwill and other intangible assets, which must be assessed for impairment at least annually. In the future, if our acquisitions do not yield expected returns, we may be required to take charges to our operating results based on this impairment assessment process, which could adversely affect our results of operations.

Our use of accounting estimates involves judgment and could adversely impact our financial results, and ineffective internal controls could adversely impact our business and operating results.

The methods, estimates, and judgments that we use in applying accounting policies have a significant impact on our results of operations. For more information on our critical accounting policies and estimates, see "Management's Discussion and Analysis of Financial Condition and Results of Operations" and Note 2 to our consolidated financial statements included elsewhere in this Annual Report. These methods, estimates, and judgments are subject to significant risks, uncertainties, and assumptions, and changes could affect our results of operations. In addition, our internal control over financial reporting may not prevent or detect misstatements because of the inherent limitations, including the possibility of human error, the circumvention or overriding of controls, or fraud. Even effective internal controls can provide only reasonable assurance with respect to the preparation and fair presentation of our consolidated financial statements.

As a result of becoming a public company, we are obligated to report on the effectiveness of our internal control over financial reporting. These internal controls may not be determined to be effective, which may harm investor confidence in our company and, as a result, the trading price of our Class A common stock.

We are required, pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting in the second annual report we file with the Securities and Exchange Commission, or the SEC. This assessment will need to include disclosure of material

weaknesses, if any, identified by our management in our internal control over financial reporting. However, as an "emerging growth company," as defined in the JOBS Act, our independent registered public accounting firm will not be required to formally attest to the effectiveness of our internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act until the later of the year following our first annual report required to be filed with the SEC, or the date we are no longer an emerging growth company. At such time, our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the level at which our controls are documented, designed or operating. Any failure of our internal control over financial reporting to be effective or our failure to implement required new or improved controls, if any, or difficulties encountered in their implementation, may harm our operating results, cause us to fail to meet our reporting obligations, and negatively impact the trading price of our Class A common stock.

We are an emerging growth company and we cannot be certain that the reduced disclosure requirements applicable to emerging growth companies will not make our Class A common stock less attractive to investors.

We are an emerging growth company, as defined under the JOBS Act. For as long as we continue to be an emerging growth company, we intend to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies including, but not limited to, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We cannot predict if investors will find our Class A common stock less attractive because we will rely on these exemptions. If some investors find our Class A common stock less attractive as a result, there may be a less active trading market for our Class A common stock and our stock price may be more volatile.

We will remain an emerging growth company until the earliest of (i) the end of the fiscal year in which we have total annual gross revenue of $1 billion or more during such fiscal year, (ii) the end of the fiscal year in which we qualify as a large accelerated filer, with at least $700 million of equity securities held by non-affiliates, (iii) the date on which we issue more than $1 billion in non-convertible debt in a three-year period, or (iv) December 31, 2020, which is the last day of the fiscal year following five years from the date of our initial public offering.

Our Board of Directors may change our strategies, policies, and procedures without stockholder approval and we may become more highly leveraged, which may increase our risk of default under our debt obligations.

Our investment, financing, leverage, and dividend policies, and our policies with respect to all other activities, including growth, capitalization, and operations, are determined exclusively by our board of directors, and may be amended or revised at any time by our board of directors without notice to or a vote of our stockholders. This could result in us conducting operational matters, making investments, or pursuing different business or growth strategies than those contemplated in this Annual Report. Further, our charter and bylaws do not limit the amount or percentage of indebtedness, funded or otherwise, that we may incur. Higher leverage also increases the risk of default on our obligations. In addition, a change in our investment policies, including the manner in which we allocate our resources across our portfolio or the types of assets in which we seek to invest, may increase our exposure to interest rate risk and liquidity risk. Changes to our policies with regards to the foregoing could materially adversely affect our financial condition, results of operations, and cash flow.

Future sales to clients outside the United States or with international operations might expose us to risks inherent in international sales which, if realized, could adversely affect our business.

An element of our growth strategy is to expand internationally. Operating in international markets requires significant resources and management attention and will subject us to regulatory, economic, and political risks that are different from those in the United States. Because of our limited experience

with international operations, any international expansion efforts might not be successful in creating demand for our services outside of the United States or in effectively selling our services in the international markets we enter. In addition, we will face risks in doing business internationally that could adversely affect our business, including:

Our business could be harmed by disruptions in network service or operational failures at our data centers (including our co-location facility) related to the storage, transmission and presentation of client data.

Our success depends on the efficient and uninterrupted operation of our data centers and service provider locations. Interruptions in service or damage to locations may be caused by natural disasters, power loss, Internet or network failures, physical damage, operator error, security breaches, computer viruses, denial-of-service attacks, or similar events. The varied types and severity of the interruptions that could occur may render our safeguards inadequate. These service interruption events could result in the corruption or loss of data and impair the processing of data and our delivery of services to clients, which could have an adverse effect on our business, operations, and financial results. Furthermore, if any of our data centers are unable to keep up with our growing needs for capacity, it could have an adverse effect on our business.

Problems faced by our third-party data center location, with the telecommunications network providers with whom we or it contract, or with the systems by which our telecommunications providers allocate capacity among their clients, including us, could adversely affect the experience of our clients and the security of the data.

Further, our ability to deliver our cloud-based services depends on the infrastructure of the Internet and a reliable network with the necessary speed, data capacity, bandwidth capacity, and security. Our services are designed to operate without interruption in accordance with our service level commitments. We have, however, experienced, and may experience in the future, interruptions and delays in services and availability from time to time. An extended period of network unavailability could negatively impact our ability to deliver acceptable or accurate services, and negatively impact our relationship with clients, which could have an adverse effect on our reputation, financial condition, and results of operations.

We rely on agreements with third parties to provide certain services, goods, technology, and intellectual property rights necessary to enable us to implement some of our applications.

Our ability to implement and provide our applications and services to our clients depends, in part, on services, goods, technology, and intellectual property rights owned or controlled by third parties, including one vendor from whom we purchase significant components of our storage architecture. These third parties may become unable to or refuse to continue to provide these services, goods, technology, or intellectual property rights on commercially reasonable terms consistent with our business practices, or otherwise discontinue a service important for us to continue to operate our applications. If we fail to replace these services, goods, technologies, or intellectual property rights in a timely manner or on commercially reasonable terms, our operating results and financial condition could be harmed. In addition, we exercise limited control over our third-party vendors, which increases our vulnerability to problems with technology and services those vendors provide. If the services, technology, or intellectual property of third parties were to fail to perform as expected, it could subject us to potential liability, adversely affect our renewal rates, and have a material adverse effect on our financial condition and results of operations.

Our reliance on third-party vendors to perform certain of our intervention toolsets could have an adverse effect on our business, results of operations and growth prospects.

We rely in part on third-party vendors to perform certain of our intervention toolsets, including supplemental patient encounters such as in-home encounters. These third parties may not perform their obligations to us in a timely and cost-effective manner, in compliance with applicable regulations, or in a manner that is in our and our clients' best interests, which could have an adverse effect on our reputation and our ability to retain and attract clients. In addition, our growth depends in part on the ability of our third-party vendors to leverage our intervention toolsets to a larger group of clients. If our third-party vendors do not perform their services at a level acceptable to us or our clients or if they are unable to leverage our intervention toolsets to a larger group of clients, it could have an adverse effect on our business, results of operations, and growth prospects.

Our quarterly operating results may fluctuate significantly, which could adversely impact the value of our Class A common stock.

Our quarterly results of operations, including our revenue, gross margin, net income, and cash flows, may vary significantly in the future, and sequential quarter-to-quarter comparisons of our operating results may not be meaningful. In addition to the other risk factors included in this section, some of the important factors that may cause sequential quarter-to-quarter fluctuations in our operating results include:

Any fluctuations in our quarterly operating results may not accurately reflect the underlying longer-term performance of our business and could cause a decline in the trading price of our Class A common stock.

Because the dual class structure of our common stock has the effect of concentrating voting control with holders of our Class B common stock, holders of our Class B common stock, including Dr. Dunleavy and Mr. Hoffmann, have significant influence over us, including control over decisions that require the approval of stockholders, which could limit your ability to influence the outcome of matters submitted to stockholders for a vote.

We are currently controlled by holders of our Class B common stock. As of the date of this Annual Report, holders of our Class B common stock beneficially own an aggregate of approximately 94% of the voting power of our common stock. In particular, Dr. Dunleavy beneficially owns an aggregate of approximately 57% of the voting power of our common stock, and Mr. Hoffmann beneficially owns an aggregate of approximately 20% of the voting power of our common stock. The shares beneficially owned by Dr. Dunleavy and Mr. Hoffmann and certain other stockholders are shares of Class B common stock, which have 10 votes per share, whereas each share of Class A common stock has one vote per share. As long as holders of our Class B common stock control at least a majority of the voting power of our outstanding common stock, they will have the ability to exercise substantial control over all corporate actions requiring stockholder approval, irrespective of how our other stockholders may vote, including the election and removal of directors and the size of our board of directors, any amendment of our certificate of incorporation or bylaws, or the approval of any merger or other significant corporate transaction, including a sale of all or substantially all of our assets. Even if their ownership falls below 50%, holders of our Class B common stock will continue to be able to exert significant influence or effectively control our decisions because of the dual class structure of our common stock. This concentrated control by our Class B common stockholders will limit or preclude your ability to influence those corporate matters for the foreseeable future and, as a result, we may take actions that holders of our Class A common stock do not view as beneficial. This dual class structure may adversely affect the market price of our Class A common stock. In addition, this structure may prevent or discourage unsolicited acquisition proposals or offers for our capital stock that you may feel are in your best interest as one of our stockholders.

We incur significantly increased costs and devote substantial management time as a result of now operating as a public company.

As a newly public company in 2015, we incur significant legal, accounting, stockholder communication, and other expenses that we did not incur as a private company. For example, we are subject to the reporting requirements of the Exchange Act, and are required to comply with the applicable requirements of the Sarbanes-Oxley Act and the Dodd-Frank Wall Street Reform and Consumer Protection Act, as well as rules and regulations subsequently implemented by the SEC, and

the NASDAQ Stock Market LLC, or NASDAQ, including the establishment and maintenance of effective disclosure and financial controls, changes in corporate governance practices, and required filing of annual, quarterly, and current reports with respect to our business and operating results. We expect that compliance with these requirements will increase our legal and financial compliance costs and will make some activities more time consuming and costly. In addition, we expect that our management and other personnel will need to divert attention from operational and other business matters to devote substantial time to these public company requirements. In particular, we expect to incur significant expenses and devote substantial management effort toward ensuring compliance with the requirements of Section 404 of the Sarbanes-Oxley Act, which will increase when we are no longer an emerging growth company, as defined by the JOBS Act. We may also need to hire additional accounting and financial staff with appropriate public company experience and technical accounting knowledge. Furthermore, we expect that the expenses necessary to communicate with our stockholders, the financial community, public relations audiences, and other such similar audiences will be significantly more than any such similar expenses have historically been for us.

We also expect that operating as a public company will make it more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. This could also make it more difficult for us to attract and retain qualified people to serve on our board of directors, our board committees, or as executive officers.

Furthermore, if we are unable to satisfy our obligations as a public company, we could be subject to delisting of our Class A common stock, fines, sanctions, and other regulatory action and potentially civil litigation, which could have a material adverse effect on our financial condition and results of operations.

The stock price of our Class A common stock may be volatile or may decline regardless of our operating performance, and you may not be able to resell your shares at or above the price at which you acquire shares of our Class A common stock.

The market price of our Class A common stock may fluctuate significantly. These fluctuations could cause you to lose all or part of your investment in our common stock since you might be unable to sell your shares at or above the price you paid. Factors, many of which are beyond our control, that could cause fluctuations in the market price of our Class A common stock include the following:

In addition, the stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many technology companies. Stock prices of many technology companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies. In the past, stockholders have filed securities class action litigation following periods of market volatility. If we were to become involved in securities litigation, it could subject us to substantial costs, divert resources and the attention of management from our business, and materially adversely affect our business.

We do not currently intend to pay dividends on our common stock and, consequently, your ability to achieve a return on your investment will depend on appreciation in the price of our Class A common stock.

Although we have paid cash dividends on our common stock in the past, we currently intend to invest any future earnings to finance the operation and growth of our business and do not expect to pay any dividends for the foreseeable future. As a result, the success of an investment in shares of our Class A common stock will depend upon future appreciation in its value, if any, and there is no guarantee that shares of our Class A common stock will appreciate in value.

Delaware law and provisions in our restated certificate of incorporation and bylaws could make a merger, tender offer, or proxy contest difficult, thereby depressing the trading price of our Class A common stock.

Our status as a Delaware corporation and the anti-takeover provisions of the Delaware General Corporation Law may discourage, delay, or prevent a change in control by prohibiting us from engaging in a business combination with an interested stockholder (generally a stockholder, who together with affiliates and associates, owns 15% or more of our voting rights) for a period of three years after the person becomes an interested stockholder, even if a change of control would be beneficial to our stockholders. In addition, our restated certificate of incorporation and bylaws contain provisions that may make the acquisition of our company more difficult, including the following:

Our restated certificate of incorporation provides that, subject to certain exceptions, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for certain stockholder litigation matters, which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

Our restated certificate of incorporation provides that, subject to limited exceptions, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, (iii) any action asserting a claim against us arising pursuant to any provision of the Delaware General Corporation Law, our restated certificate of incorporation or our restated bylaws, or (iv) any action asserting a claim against us that is governed by the internal affairs doctrine. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock shall be deemed to have notice of and to have consented to the provisions of our restated certificate of incorporation described above. This choice of forum provision may limit a stockholder's ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our directors, officers or other employees, which may discourage lawsuits with respect to such claims. Alternatively, if a court were to find the choice of forum provision contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, operating results and financial condition.

If securities or industry analysts do not publish research or reports about our business, if they adversely change their recommendations regarding our shares, or if our results of operations do not meet their expectations, the share price and trading volume of our Class A common stock could decline.

The trading market for our Class A common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. We do not have any control over these analysts. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause the share price or trading volume of our Class A common stock to decline. Moreover, if one or more of the analysts who cover us, express views regarding us that may be perceived as negative or less favorable than previous views, downgrade our stock, or if our results of operations do not meet their expectations, the share price of our Class A common stock could decline.

Our corporate headquarters is located in Bowie, Maryland, where we occupy approximately 110,000 square feet under a lease agreement that expires in August 2018. In addition, we lease an aggregate of approximately 216,000 square feet at the following locations: Columbia, Maryland; a second facility in Bowie, Maryland; Herndon, Virginia; Lansing, Michigan; Washington, DC; and Phoenix, Arizona. We own one property in Snellville, Georgia, which is approximately 12,000 square feet. In addition, we maintain a number of leases for smaller office facilities in various locations in the regions of our clients coinciding with specific client needs.

From time to time, we may be involved in various legal proceedings and subject to claims that arise in the ordinary course of business. Although the results of litigation and claims are inherently unpredictable and uncertain, we are not currently a party to any legal proceedings the outcome of which, if determined adversely to us, are believed to, either individually or taken together, have a material adverse effect on our business, operating results, cash flows or financial condition. Regardless of the outcome, litigation has the potential to have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors.

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

Our Class A common stock is listed on the NASDAQ Global Select Market under the symbol "INOV." Initial trading of our Class A common stock commenced on February 12, 2015. Accordingly, no market for our common stock existed prior to that date. On February 12, 2015, we offered our IPO at a price to the public of $27.00 per share. The following table lists quarterly information on the price range of our Class A common stock based on the high and low reported sale prices for our Class A common stock as reported by NASDAQ for the periods indicated below:

The following performance graph and related information shall not be deemed "soliciting material" or to be "filed" with the Securities and Exchange Commission, nor shall such information be incorporated by reference into any future filing under the Securities Act of 1933 or Securities Exchange Act of 1934, each as amended, except to the extent that we specifically incorporate it by reference into such filing.

Set forth below is a graph comparing the cumulative total stockholder return on our Class A common stock with the NASDAQ Composite-Total Returns Index and the NASDAQ Computer and Data Processing Index since February 12, 2015 (the date our Class A common stock initialy traded), through December 31, 2015, assuming that an investment of $100 was invested in our common stock at $27 per share, and each index referenced at quoted prices on February 12, 2015, and assumes that any dividends were reinvested on the relevant payment dates. The following performance graph is historical and not necessarily indicative of future price performance.

The following table was used to prepare the chart above, assumes $100 was invested at the close of market on February 12, 2015, which was our initial trading day, and illustrates the value of the investment based on quoted prices as of the indicated dates:

As of February 15, 2016, there were 17 stockholders of record of our Class A common stock. However, because many shares of our common stock are held by brokers and other institutions on behalf of stockholders, we believe there are substantially more beneficial holders of our common stock than record holders. As of February 15, 2016, there were 52 stockholders of record of our Class B common stock.

Our board of directors does not currently intend to declare and pay dividends on our common stock. However, our board of directors will periodically reevaluate our dividend policy and may determine to pay dividends in the future. Any future determination to declare cash dividends will be at the sole discretion of our board of directors.

The following table sets forth the cash dividends per share of our common stock that our board of directors declared during the years ended December 31, 2015, 2014, 2013, and 2012, respectively:

On February 18, 2015, we completed our IPO of 22,222,222 shares of Class A common stock and, upon the underwriters' exercise of their option to purchase additional shares, issued an additional 3,142,581 shares of Class A common stock for a total of 25,364,803 shares issued. All of the shares issued in the IPO were primary shares offered by us as none of our stockholders sold any shares in the IPO. The offering price of the shares sold in the IPO was $27.00 per share, resulting in net proceeds to us, after underwriters' discounts and commissions and other expenses payable by us, of $639.1 million. All of the shares were sold pursuant to our registration statement on Form S-1, as amended (File No. 333-201321), that was declared effective by the SEC on February 11, 2015. Goldman, Sachs & Co., Morgan Stanley & Co. LLC, and Citigroup Global Markets Inc. acted as joint book-running managers for the IPO and as representatives of the underwriters.

The principal purposes of our IPO were to create a public market for our Class A common stock and thereby enable future access to the public equity markets by us and our employees, and obtain additional capital. On September 1, 2015, we used approximately $126.2 million of the net proceeds from the IPO to complete the acquisition of Avalere. We intend to use the remaining net proceeds to us from our IPO for working capital and other general corporate purposes; however, we do not currently have any specific uses of the remaining net proceeds. Additionally, we may use a portion of the remaining net proceeds for additional acquisitions of complementary businesses, technologies, or other assets, or to repay outstanding indebtedness.

The following table sets forth certain information with respect to common stock purchased by the Company for the three-month period ended December 31, 2015.

2015 Employee Stock Purchase Plan—The ESPP became effective on the date of the completion of our initial public offering. The ESPP enables eligible employees to purchase shares of our Class A common stock at a discount through participation in discrete offering periods. Shares of Class A common stock purchased under the ESPP will either be issued by the Company or acquired directly from third parties in the open market. On September 1, 2015, we directed the plan administrator to purchase 30,689 shares of Class A common stock in the open market for a total of $664 thousand, for issuance to the ESPP participants at a discounted price of $18.61 per share; there were no other open market purchases pursuant to the Plan in the fiscal year ended December 31, 2015. We may, in our sole discretion, based on market conditions, relative transaction costs and our need for additional capital, continue to instruct the plan administrator to make semi-annual open market purchases of Class A common stock for ESPP participants to coincide with the ESPP's designated semi-annual purchase dates.

2015 Omnibus Incentive Plan—We issue restricted stock units ("RSUs") and restricted stock awards ("RSAs") as part of our 2015 Omnibus Incentive Plan (the "2015 Plan"), which was adopted by our board of directors on January 14, 2015 and approved by our stockholders. Shares of common stock issued upon vesting of RSUs and RSAs under the 2015 Plan will be either issued by the Company or acquired directly from third parties in the open market or in privately negotiated transactions. We may, in our sole discretion, determine the source of shares issuable upon vesting of RSUs and RSAs available through the 2015 Plan based on market conditions, relative transaction costs and our need for additional capital. In the future, we may direct the plan administrator to purchase shares of Class A common stock in the open market to cover vested RSUs and RSAs. During the fiscal year ended December 31, 2015, we did not make any open market purchases pursuant to the 2015 Plan.

See Item 12, "Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters" for information regarding securities authorized for issuance.

The following table sets forth selected consolidated financial data for the years presented and at the dates indicated below. We have derived the selected consolidated statements of operations data for the years ended December 31, 2015, 2014, and 2013 from our audited consolidated financial statements included elsewhere in this annual report on Form 10-K. We have derived the selected consolidated balance sheet data as of December 31, 2015 and 2014 from our audited consolidated financial statements included elsewhere in this annual report on Form 10-K. The consolidated statement of operations data for the years ended December 31, 2012 and 2011 and the consolidated balance sheet data as of December 31, 2013, 2012 and 2011 are derived from consolidated financial statements that are not included in this annual report on Form 10-K. In our opinion, such financial statements include all adjustments, consisting only of normal recurring adjustments, that we consider necessary for a fair presentation of the financial data set forth in those statements. In the table below we have included measures, "Adjusted EBITDA," "Adjusted EBITDA margin," and "Non-GAAP net income," that are not presented in accordance with GAAP. A discussion of why we utilize these non-GAAP measures and reconciliations to corresponding GAAP measures are provided below.

Our historical results are not necessarily indicative of our results in any future periods. The summary of our consolidated financial data set forth below should be read together with our consolidated financial statements and related notes, as well as the sections entitled "Management's

Discussion and Analysis of Financial Condition and Results of Operations," included elsewhere in this Annual Report.

We provide the measures Adjusted EBITDA, Adjusted EBITDA margin, and Non-GAAP net income as additional information for its operating results. These measures are not prepared in accordance with, or an alternative for accounting principles generally accepted in the United States ("GAAP") and may be different from non-GAAP measures used by other companies.

Investors frequently have requested information from management regarding depreciation, amortization other non-cash charges, such as stock-based compensation, as well as the impact of non-comparable items and management believes, based on discussions with investors, that these non-GAAP measures enhance investors' ability to assess our historical and projected future financial performance. While we believe these non-GAAP financial measures provide useful supplemental information to investors, there are limitations associated with the use of non-GAAP financial measures. For example, one limitation of Adjusted EBITDA is that it excludes depreciation and amortization, which represents the periodic costs of certain capitalized tangible and intangible assets used in generating revenues in our business. We compensate for these limitations by using these non-GAAP financial measures as supplements to GAAP financial measures and by reviewing the reconciliations of the non-GAAP financial measures to their most comparable GAAP financial measures. Investors are encouraged to review the reconciliations of these non-GAAP financial measures to the comparable GAAP measures that are provided below.

These non-GAAP measures include financial information that is prepared in accordance with GAAP and presented in our consolidated financial statements and are used to evaluate our business, measure our performance, develop financial forecasts and make strategic decisions and as an important factor in determining variable compensation. Reconciliations of net income, the most closely comparable GAAP financial measure, to Adjusted EBITDA and Non-GAAP net income are presented below.

We define Adjusted EBITDA as net income calculated in accordance with GAAP, adjusted for the impact of depreciation and amortization, interest expense, interest income, provision for income taxes, stock-based compensation, acquisition costs, tax on equity exercises, other non-comparable income and expenses, and certain legal costs. We have provided below a reconciliation of net income, which is the most directly comparable GAAP financial measure, to Adjusted EBITDA.

Adjusted EBITDA margin is our calculation of Adjusted EBITDA divided by revenue calculated in accordance with GAAP.

We use Adjusted EBITDA and Adjusted EBITDA margin as a supplemental measure of our performance to gain insight into our operating performance. We use Adjusted EBITDA and Adjusted EBITDA margin as a key metric to assess our ability to increase revenues while controlling expense growth and the scalability of our business model. We believe that the exclusion of the expenses eliminated in calculating Adjusted EBITDA and Adjusted EBITDA margin provides management and investors a useful measure for period-to-period comparisons of our core business and operating results by excluding items that are not comparable across reporting periods or that do not otherwise relate to our ongoing operating results. Accordingly, we believe that Adjusted EBITDA and Adjusted EBITDA margin provide useful information to investors and others in understanding and evaluating our operating results. However, use of Adjusted EBITDA and Adjusted EBITDA margin as analytical tools has limitations, and you should not consider them in isolation or as substitutes for analysis of our financial results as reported under GAAP. In addition, other companies, including companies in our industry, might calculate Adjusted EBITDA and Adjusted EBITDA margin or similarly titled measures differently, which may reduce their usefulness as comparative measures.

The following table presents a reconciliation of net income to Adjusted EBITDA for each of the periods indicated:

We define Non-GAAP net income as net income adjusted to exclude tax-affected stock-based compensation expense, acquisition costs, amortization of acquired intangible assets, tax on equity exercises, and other non-comparable income and certain expenses.

We use Non-GAAP net income as a supplemental measure of our performance to gain insight into our financial performance. We use Non-GAAP net income as a key metric to assess our ability to increase revenues while controlling expense growth and the scalability of our business model. We believe that the exclusion of the expenses eliminated in calculating Non-GAAP net income provides management and investors a useful measure for period to period comparisons of our core business and financial results by excluding items that are not comparable across reporting periods or that do not otherwise relate to our ongoing financial results.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with our "Selected Financial Data" and our consolidated financial statements and notes thereto appearing elsewhere in this annual report on Form 10-K. In addition to historical consolidated financial information, the following discussion and analysis may contain forward-looking statements that involve risks, uncertainties and assumptions. Our actual results could differ materially from those anticipated by forward-looking statements as a result of many factors. We discuss factors that we believe could cause or contribute to these differences below and elsewhere in this annual report on Form 10-K, including those set forth under "Risk Factors" and "Special Note Regarding Forward-Looking Statements."

We are a leading technology company that combines advanced cloud-based data analytics and data-driven intervention platforms to achieve meaningful impact in clinical and quality outcomes, utilization, and financial performance across the healthcare landscape. We deliver value to our clients by turning data into insights and those insights into action. Currently, our clients include health plans, hospitals, physicians, patients, pharmaceutical companies and researchers.

Our large proprietary datasets, advanced integration technologies, sophisticated predictive analytics, and deep subject matter expertise allow us to provide seamless, end-to-end platforms that bring the benefits of big data and large-scale analytics to the point of care. Our data analytics platforms identify gaps in care, quality, data integrity, and financial performance in our clients' datasets. Our data-driven intervention platforms enable our clients to take the insights derived from the analytics and implement unique, patient-level solutions, drive impact and enhance patient engagement. Through these capabilities, and those of our subsidiary Avalere, which offers data-driven advisory services and business intelligence to more than 200 pharmaceutical and life sciences enterprises, as well as an extensive array of client relationships with payors, providers and research institutions, we are able to drive high-value impact, improving quality and economics for health plans, accountable care organizations ("ACOs"), hospitals, physicians, consumers and pharma/life-sciences researchers.

We generate the substantial majority of our revenue through the sale or subscription licensing of our data analytics and data-driven intervention platform services. Since our inception, we have experienced significant growth.

For the year ended December 31, 2015, our revenue was $437.3 million, representing 21% growth over the year ended December 31, 2014. For the year ended December 31, 2015, we generated Adjusted EBITDA of $151.6 million, representing a 35% Adjusted EBITDA margin and 13% growth over the same period in the prior year. Net income for the year ended December 31, 2015 was $66.1 million, representing 15% of revenue and a 1% increase over the year ended December 31, 2014. Non-GAAP net income for the year ended December 31, 2015 was $75.4 million, representing 17% of revenue and a 7% increase over the same period in 2014. Adjusted EBITDA and Non-GAAP net income are non-GAAP measures. Adjusted EBITDA and Non-GAAP net income are measures that are not presented in accordance with GAAP. For a reconciliation of net income to Adjusted EBITDA and Non-GAAP net income, see "Non-GAAP Financial Measures," provided in Item 6—Selected Financial Data.

On February 18, 2015, we completed our IPO of 22,222,222 shares of Class A common stock and, upon the underwriters' exercise of their option to purchase additional shares, issued an additional 3,142,581 shares of Class A common stock for a total of 25,364,803 shares issued. All of the shares issued in the IPO were primary shares offered by us as none of our stockholders sold any shares in the IPO. The offering price of the shares sold in the IPO was $27.00 per share, resulting in net proceeds to us, after underwriters' discounts and commissions and other expenses payable by us, of $639.1 million. Our Class A common stock is currently traded on the NASDAQ Global Select Market under the symbol "INOV."

On September 1, 2015, pursuant to the terms of a Share Purchase Agreement between the Company and Avalere (the "Purchase Agreement"), we acquired 100 percent of the capital stock of Avalere for an aggregate stated purchase price of $140.0 million, consisting of cash and 235,737 shares of the Company's Class A common stock which are subject to resale restrictions. The addition of Avalere, with its more than 200 pharmaceutical and life sciences clients, as well as an extensive array of client relationships with payors, providers and research institutions, is expected to expand our capabilities and client base into the expansive and adjacent markets of the pharmaceutical and life sciences industry. We incurred transaction costs in connection with the acquisition of approximately $1.5 million, which are included in general and administrative expenses. See Note 3 (Business Combinations), included elsewhere within this annual report on Form 10-K for more information.

During 2015 Inovalon announced the introduction of Data Diagnostics™ to the healthcare marketplace. This technology provides a suite of hundreds of patient-specific analyses that can be ordered individually by clinicians on demand with the answer provided within seconds—all without leaving the clinician's workflow. The capability leverages vast amounts of data across billions of medical events, interconnectivity, and high-speed cloud-based analytics to allow physician organizations, health

plans, accountable care organizations (ACOs), hospitals, integrated healthcare delivery systems, ASO employer groups, government programs, and individual physicians to achieve valuable clinical insights, strong clinical and quality outcomes, utilization efficiency, and overall financial performance on demand and in real time. The technology is delivered in collaboration with Quest Diagnostics, the nation's largest laboratory organization, providing large-scale distribution to clinicians through Quest's more than 200,000 Care360® provider portal installations and more than 400 integrated EHR platforms serving approximately half of the physicians and hospitals in the United States. During 2015 Inovalon invested significant resources as part of the development and anticipated operation and support of Data Diagnostics™. While still in the early stages of this platform's introduction, initial feedback from the marketplace has been very positive.

We review a number of metrics, including the key metrics shown in the table below. We believe that these metrics are indicative of our overall level of analytical activity and the underlying growth in our business. (in thousands, except percentages)

	Year Ended December 31,

	2015			2014			2013

(1): MORE² Registry® dataset metrics, and Trailing 12 month Patient Analytics Months (PAM), each of which is presented in the table, are key operating metrics that management uses to assess our level of operational activity. While we believe that each of these metrics is indicative of our overall level of analytical activity and the underlying growth in our business, increases or decreases in these metrics do not necessarily correlate to proportional increases or decreases in revenue, Adjusted EBITDA, net income or Non-GAAP net income. For instance, although increased levels of analytical activity historically have corresponded to increases in revenue over the long term, differences in fees charged for different analytical packages exist and differences in how analytics trigger the applicability of our data-driven intervention platforms may result in increases in analytical activity that do not result in proportional increases in revenue, Adjusted EBITDA, net income or Non-GAAP net income (and vice versa). Accordingly, while we believe the presentation of these operating metrics is helpful to investors in understanding our business, these metrics have limitations and should not be considered as substitutes for analysis of our financial results reported under GAAP. In addition, we believe that other companies, including companies in our industry, do not present similar operating metrics and that there is no commonly accepted method of calculating these metrics, which may reduce their usefulness as comparative measures.
(2): Unique patient count is defined as each unique, longitudinally matched, de-identified natural person represented in our MORE² Registry® as of the end of the period presented.

(3): Medical event count is defined as the total number of discrete medical events as of the end of the period presented (for example, a discrete medical event typically results from the presentation of a patient to a physician for the diagnosis of diabetes and congestive heart failure in a single visit, the presentation of a patient to an emergency department for chest pain, etc.).
(4): Patient Analytics Months, or PAM, is defined as the sum of the analytical processes performed on each respective patient within patient populations covered by clients under contract. As used in the metric, an "analytical process" is a distinct set of data calculations undertaken by us which is initiated and completed by our analytical platform to examine a specific question such as whether a patient is believed to have a condition such as diabetes, or worsening of the disease, during a specific time period.
(5): Revenue mix excludes advisory services.
(6): Revenue from data analytics subscriptions is defined as revenue that results from subscription agreements/contracts for the provision of data analytics (which include such components as the company's data integration, data management, data analytics, and data reporting) services.
(7): Revenue from data-driven intervention platform services is defined as revenue that results from contracts for the provision of data- driven intervention platform services. This revenue is further broken down into revenue achieved through fully automated processes (i.e., those processes that require no material variable-based labor component) and partially automated processes (i.e., those processes that require certain material variable-based labor components).

A number of factors influence our growth and performance. We see many of these factors as being more quantitatively driven, such as the rate of growth of the underlying data counts within our datasets, the ongoing investment in innovation, the number of statement of work contracts maintained by us, and our level of analytical activity. Additionally, there are several factors that influence our growth and performance that are less quantitatively driven, including seasonality, macro-economic forces, and trends within healthcare (such as payment models, incentivization, and regulatory oversight), that can be driven by changes in federal and state laws and regulations, as well as private sector market forces.

Growth of Datasets. Healthcare costs in the United States have been increasing significantly for many years. This rise in healthcare costs has driven a broad transition from consumption-based payment models to quality and value-based payment models across the healthcare landscape. As a result, the specific disease and comorbidity status, clinical and quality outcomes, resource utilization, and care details of the individual patient have become increasingly relevant to the various constituents across the healthcare delivery system. Concurrently, the count and complexity of diseases, diagnostics, and treatments—as well as payment models and regulatory oversight requirements—have soared. In this setting, granular data has become critical to determining and improving quality and financial performance in healthcare. Our MORE² Registry® is our largest principal dataset and serves as a proxy for our general growth of datasets within Inovalon. The growth of our datasets that inform our analytical capabilities and comparative analytics is a key aspect of our provision of value to our clients and is indicative of our overall growth and capabilities.

Innovation and Platform Development. Our business model is based upon our ability to deliver value to our clients through the combination of advanced, cloud-based data analytics and data-driven intervention platforms focused on the achievement of meaningful and measureable improvements in clinical quality outcomes and financial performance in healthcare. Our ability to deliver this value is dependent in part on our ability to continue to innovate, design new capabilities, and bring these capabilities to market in an enterprise scale. Our continued ability to innovate our platform and bring differentiated capabilities to market is an important aspect of our business success. Our investment in

innovation includes costs for research and development, capitalized software development, and capital expenditures related to hardware and software platforms on which our data analytics and data-driven interventions capabilities are deployed as summarized below (in thousands, except percentages).

Data Analytics and Data-Driven Intervention Mix. Our business and operational models are highly scalable and leverage variable costs to support revenue generating activities. Our data analytic service costs are less variable in nature and require lower incremental capital expenditures. As a result, following initial development and deployment investments, our big data analytics platform and data technology capabilities allow us to process significant volumes of transactions with lower incremental costs. Conversely, our data- driven intervention costs are generally variable in nature and require incremental costs to generate additional revenue. As a result, the mix of our data analytics and data interventions activities affects our financial performance.

Client and Analytical Process Count Growth. Our business is generally driven by the number of underlying patients for which our analytics and data-driven intervention platforms are being utilized. As such, we track the number of analytical processes that we run on patients each month in fulfillment of our client contracts, as totaled for the trailing 12 months. This metric is referred to as the Trailing 12 Month Patient Analytical Months, or PAM. We believe that PAM is indicative of our overall level of analytical activity, and we expect our period-to-period comparisons of our PAM to be indicative of underlying growth of our business, although changes in levels of analytical activity do not always directly translate to changes in financial performance of our business. Differences in fees charged for different analytical packages exist and differences in how analytics trigger the applicability of our data-driven intervention platforms may result in increases in analytical activity that do not result in proportional increases in revenue, Adjusted EBITDA, net income or Non-GAAP net income (and vice versa). Therefore, in situations in which a new SOW is initiated for analytical processes that have a higher than average fee rate, revenue could expand disproportionately faster than the increase in PAM.

Likewise, as was the case in the year ended December 31, 2013, the loss of an SOW for analytical processes that have a higher than average fee rate can negatively affect revenue disproportionately more than PAM. Further, in 2013, the initiation of several new SOWs for various analytical processes that commanded, when taken together, a lower than average fee rate offset the reduction in revenue from the aforementioned terminated SOW, while PAM was more than offset, and thus increased.

Seasonality. The nature of our customers' end-market results in seasonality reflected in both revenue and cost of revenue differences during the year. Regulatory impact of data submission deadlines in, for example, March, June, September, and January drive predictable timing of analytics and data processing activity variances from quarter to quarter. Further, regulatory clinical encounter deadlines of June 30th and December 31st drive predictable intervention concentrations variances from quarter to quarter. The timing of these factors results in analytical and intervention activity mix variances which predictably impact financial performance from quarter to quarter. The trend of higher client focus on "watchful waiting" has increasingly shifted intervention platform usage to later in the year.

Macro-Economic and Macro-Industry Trends. Our clients are affected, sometimes directly, and sometimes counter-intuitively, by macro- economic trends such as economic growth (or economic recession), inflation, and unemployment. Further, industry trends in federal and state laws and regulations, as well as emerging trends in private sector payment models, affect our clients' businesses and their need for technologies and services to support these challenges. These factors have various effects on our business, and on occasion have resulted in the slowing or cessation of the decision-making process by clients adopting our technologies and services. On the other hand, changes in macro-economic trends and the industry landscape have accelerated the need for our technologies and services from time-to-time, particularly as regulators introduce complex requirements with which our clients must comply.

Shift to Fully Automated Data-Driven Intervention Platform Services. We view the decreased proportion of revenue derived from partially automated data-driven intervention platform services as a positive reflection of our cloud-based interconnectivity and automation capabilities. The proportion of our revenue derived from pure data analytics and fully automated data-driven intervention platform services revenue is expected to continue to expand over time as a percentage of total revenue as a result of our continued expansion of our cloud-based interconnectivity technologies and the continued expansion of interconnectivity within the healthcare landscape. In order to drive value for our clients and serve them irrespective of their level of connectivity, we continue to provide cloud-based partially automated data-driven intervention platform services, converting the performance of such services to cloud-based fully automated data-driven intervention platform services wherever possible. As the healthcare infrastructure becomes more interconnected and our integration and interconnectivity technologies continue to expand, we believe that we will be able to achieve more rapid implementation, and greater value impact, at more efficient costs.

We earn revenue through the sale or subscription licensing of our cloud-based data analytics and data-driven intervention platform services.

Cloud-based data analytics solution revenue accounted for approximately 54.2%, 57.7%, and 48.6%, of our consolidated revenue during the years ended December 31, 2015, 2014, and 2013, respectively. These percentages include software subscription licensing revenue of approximately 3.2%, 3.6%, and 3.6%, of our consolidated revenue during the years ended December 31, 2015, 2014, and 2013, respectively. Our cloud-based data analytics services are performed either at the beginning of a

data-driven intervention process, which typically aligns with regulatory submission deadlines, or on a monthly basis, depending on the particular client's needs. Data analytics revenue is driven primarily by the number of identified gaps in care, quality, data integrity, and financial performance identified in a client's dataset, the number of unique patients in a client's dataset, a minimum data analytics processing fee, and a contractually negotiated transactional price for each identified gap or unique patient. Subscription licensing revenue is driven primarily by the number of clients, the number of unique patients in a client's population dataset, the number of analytical services contracted for by a client, and the contractually negotiated price of such services.

Cloud-based data-driven intervention platform services revenue accounted for approximately 45.8%, 42.3%, and 51.4%, of our consolidated revenue during the years ended December 31, 2015, 2014, and 2013, respectively. Data-driven intervention platform service revenue is further broken down into revenue that is generated from fully automated processes (i.e., those processes that require no material variable-based labor components) and partially automated processes (i.e., those processes that require certain material variable-based labor components). Respectively, for the years ended December 31, 2015, 2014, and 2013, revenue from fully automated processes accounted for 12.4%, 7.3%, and 4.3%, of data-driven intervention platform services revenue and revenue from partially automated processes accounted for 33.4%, 35.0%, and 47.1%, of data- driven intervention platform services revenue.

As many of our analytical capabilities are designed to identify gaps in care, quality, utilization, compliance, and/or other gaps that may impact our clients' achievement of greater healthcare quality and financial performance, our cloud-based data driven intervention platform services revenue is driven primarily by the results of our data analytic processes and our clients' desire to utilize our cloud-based intervention platforms to resolve such identified gaps. Informed by our analytics, our cloud-based intervention platforms are designed to enable the resolution of specific gaps through the aggregation of specific data or achievement of specific impact. Revenue from our intervention platform utilization is generally driven by the quantity and type of completed interventions enabled by our platform, and a contractually negotiated transactional price for each such intervention. See "Critical Accounting Policies—Revenue Recognition" for a more detailed discussion of our revenue recognition policy.

Cost of revenue consists primarily of expenses for employees who provide direct contractual services to our clients, including salaries, benefits, discretionary incentive compensation, employment taxes, severance, and equity compensation costs. Cost of revenue also includes expenses associated with the integration, and verification of data and other service costs incurred to fulfill our revenue contracts. Cost of revenue does not include allocated amounts for occupancy expense and depreciation and amortization. Many of the elements of our cost of revenue are relatively variable and semi-variable, and can be reduced in the near-term to offset any decline in our revenue.

Our business and operational models are designed to be highly scalable and leverage variable costs to support revenue generating activities. While we expect to grow our headcount over time to capitalize on our market opportunities, we believe our increased investment in automation, electronic health record integration capabilities, and economies of scale in our operating model, will position us to grow our revenue at a greater rate than our cost of revenue.

Sales and marketing expense consists primarily of employee-related expenses, including salaries, benefits, commissions, discretionary incentive compensation, employment taxes, severance, and equity compensation costs for our employees engaged in sales, sales support, business development, and marketing. Sales and marketing expense also includes operating expenses for marketing programs,

research, trade shows and brand messages, and public relations costs. Our sales and marketing expense excludes any allocation of occupancy expense and depreciation and amortization.

We expect our sales and marketing expenses to increase as we strategically invest to expand our business. We expect to hire additional sales personnel and related support personnel to capture an increasing amount of our market opportunity. As we scale our sales and marketing activities in the short to medium term, we expect these expenses to increase in both absolute dollars and as a percentage of revenue.

Research and development expense (one component of our investment in innovation) consists primarily of employee-related expenses, including salaries, benefits, discretionary incentive compensation, employment taxes, severance, and equity compensation costs for our software developers, engineers, analysts, project managers, and other employees engaged in the development and enhancement of our service offerings. Research and development expense also includes certain third party consulting fees. Our research and development expense excludes any allocation of occupancy expense and depreciation and amortization.

We expect to continue our focus on developing new data analytics and data-driven intervention platforms and enhancing our existing data analytics and data-driven intervention platforms. As a result, we expect our research and development expense to increase in absolute dollars, although it may vary from period to period as a percentage of revenue.

Our general and administrative expense consists primarily of employee-related expenses including salaries, benefits, discretionary incentive compensation, employment taxes, severance, and equity compensation costs, for employees who are responsible for management information systems, administration, human resources, finance, legal, and executive management. General and administrative expense also includes occupancy expenses (including rent, utilities, communications, and facilities maintenance), professional fees, consulting fees, insurance, travel, and other expenses. Our general and administrative expense excludes depreciation and amortization.

We expect our general and administrative expense to increase as we expand our business and incur the incremental costs associated with being a public company. However, excluding certain increases as a result of being a public company, we expect our general and administrative expense to grow at a lower rate than revenue.

Our depreciation and amortization expense consists primarily of depreciation of fixed assets, amortization of capitalized software development costs, and amortization of acquisition-related intangible assets.

Realized loss on short-term investments consists of losses realized upon the sale of certain of the Company's available-for-sale securities, prior to their maturity. The losses were incurred as the value of the available-for-sale securities declined from the date of purchase to the date of sale.

Provision for income taxes consists of federal and state income taxes in the United States and foreign income taxes from the territory of Puerto Rico, including deferred income taxes reflecting the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

2015 Compared with 2014. Revenue during the year ended December 31, 2015 increased by approximately $75.7 million, or 21%, as compared with the year ended December 31, 2014. The increase was primarily attributable to an increase in revenue from new clients of $36.0 million along with a net increase of $39.7 million from existing clients. Revenue for 2015 includes $17.5 million related to the acquisition of Avalere.

2014 Compared with 2013. Revenue during the year ended December 31, 2014 increased by approximately $65.7 million, or 22%, as compared with the year ended December 31, 2013. The increase was primarily attributable to an increase in revenue from new clients of $50.5 million along with a net increase of $15.2 million from existing clients.

2015 Compared with 2014. In 2015, cost of revenue increased by approximately $33.4 million, or 30%, compared with the year ended December 31, 2014. The increase in cost of revenue was primarily due to the corresponding increase in revenue of $75.7 million or 21%, during the period and also resulted from an increase in employee-related expenses related partially to the newly acquired data-driven advisory services service line and a greater volume of data-driven intervention platform services as a percentage of total revenue. Cost of revenue as a percentage of revenue was 33% in 2015 compared to 31% in 2014.

2014 Compared with 2013. In 2014, cost of revenue decreased by approximately $7.3 million, or 6%, as compared to the year ended December 31, 2013, despite the increase in revenue of approximately $65.7 million or 22%, over the same period. The $7.3 million decrease in cost of revenue was primarily due to a reduction in employee related expenses. The reduction in employee related expenses was primarily enabled by advances in our technology platform efficiency and a shift in revenue mix towards a greater proportion of analytics versus data-driven intervention services, as well as a greater proportion of automation within the data-driven intervention services mix. Cost of revenue as a percentage of revenue was 31% in 2014 compared to 41% in 2013.

2015 Compared with 2014. In 2015, sales and marketing expenses increased by approximately $7.5 million, or 106%, compared to 2014. The increase was primarily attributable to increased employee related expenses of approximately $6.5 million, and marketing program spend of approximately $1.0 million, both of which was driven by our investment in additional sales personnel to focus on adding new clients and capturing an increased amount of our market opportunity, as well as the addition of the sales and marketing personnel acquired with Avalere.

2014 Compared with 2013. In 2014, sales and marketing expenses increased by $1.2 million, or 20%, compared to 2013. The increase primarily was attributable to an increase in employee-related costs.

2015 Compared with 2014. In 2015, research and development expenses decreased $2.8 million as a result of incremental capitalization of internally developed software efforts related to our on-going investment in platform and product innovation, and was partially offset by an increase of $2.0 million, which includes $1.0 million attributable to stock based compensation expense, attributable to an increase in employee related expenses and professional fees.

2014 Compared with 2013. In 2014, research and development expense increased by $1.9 million, or 9%, compared to 2013. The increase was attributable to our on-going investment in innovation and platform development.

2015 Compared with 2014. In 2015, general and administrative expense increased by approximately $26.5 million, or 30%, compared with 2014. Throughout the second half of 2014 and throughout 2015, we increased our investment in incremental personnel to support our growth and our transition from a private to a public company. Our investment resulted in an increase in employee related costs of $22.4 million, which includes an increase of approximately $3.1 million related to stock-based compensation expense and an increase of $7.5 million related to our growth and expansion. In addition, general and administrative expenses for 2015 includes incremental expenses that are not comparable to the prior year, comprised of $1.5 million for acquisition-related transaction costs, $2.9 million of post-acquisition contingent consideration expense related to the acquisition of Avalere, and $0.7 million for employer taxes related to stock option awards exercised by employees. The increases in general and administrative expenses for 2015 were partially offset by capitalization of internal-use software development costs of $1.0 million compared to the prior period.

2014 Compared with 2013. In 2014, general and administrative expense increased by approximately $7.9 million, or 10%, compared to 2013. The increase was primarily attributable to an increase in employee-related costs of $4.2 million, which includes an increase of approximately $1.1 million related to stock based compensation expense, professional fees of $1.8 million, occupancy costs of $1.1 million, and software licensing and maintenance expenses of $0.5 million.

2015 Compared with 2014. In 2015, depreciation and amortization expense increased by approximately $2.8 million, or 14%, compared to 2014. The increase in depreciation and amortization expense is primarily attributable to additional amortization expense for intangible assets recorded in the Avalere acquisition.

2014 Compared with 2013. In 2014, depreciation and amortization expense increased by approximately $4.4 million, or 28%, compared to 2013. The increase in depreciation and amortization expense primarily was attributable to an increase in amortization expense of capitalized software of $4.5 million as a result of accelerating amortization on software expected to be decommissioned due to the successful development of a next generation software service.

2015 compared with 2014. The realized investment losses for 2015 are attributable to sales of certain of the Company's available-for-sale short-term investments, prior to maturity, which the Company initiated and completed during the year ended December 31, 2015. Funds generated from such sales of available-for-sale short term investments were used to fund the Company's acquisition of Avalere. Sales of the Company's available-for-sale, short term investments may be required from time-to-time to fund similar strategic initiatives and such sales may result in realized gains or losses, depending on the value of the securities at the time of liquidation.

2015 compared with 2014. In 2015, interest income increased by approximately $3.0 million compared with 2014. Interest income for 2015 is attributable to earnings derived from the Company's available-for-sale short-term investments.

2015 Compared with 2014. In 2015, interest expense increased by approximately $3.1 million compared to 2014. The increase was attributable to interest expense on the $300.0 million Term Loan Facility borrowed on September 19, 2014.

2014 Compared with 2013. In 2014, interest expense increased by approximately $1.3 million compared to 2013. The increase was attributable to interest expense on the $300.0 million Term Loan Facility borrowed on September 19, 2014.

2015 Compared with 2014. In 2015, provision for income taxes increased by approximately $5.3 million, or 12%, compared to 2014. The growth of our operations resulted in a $2.4 million increase in income taxes for the year ended December 31, 2015. In addition, expected state income taxes, net of federal income tax benefit and related deferred tax adjustments increased approximately $2.9 million resulting primarily from changes in revenue sourcing methodology passed into legislation by each of New York State and New York City. Primarily, as a result of the aforementioned statutory income tax legislation changes, our effective tax rate increased to 42% for the year ended December 31, 2015 from 40% for the year ended December 31, 2014.

2014 Compared with 2013. In 2014, provision for income taxes increased by approximately $23.7 million, or 121%, compared to 2013. The increase in period-over-period income tax expense was attributable to our increase in income from operations resulting from our increase in revenues and enhancement in margins. Our effective income tax rate in 2014 was 40% compared to 38% in 2013. The increase in our effective income tax rate was due primarily to an increase in our effective state income tax rate.

The following table sets forth our unaudited consolidated statement of operations data for each of the quarters in the years ended December 31, 2015 and 2014. The unaudited quarterly statement of operations data set forth below have been prepared on a basis consistent with our audited annual consolidated financial statements and include, in our opinion, all normal recurring adjustments necessary for a fair statement of the financial information contained in those statements. Our historical results are not necessarily indicative of the results that may be expected in the future. The following quarterly financial data should be read in conjunction with our audited consolidated financial statements and the related notes included elsewhere in this Annual Report. In the table below we have included measures, "Adjusted EBITDA" and "Non-GAAP net income," that are not presented in accordance with GAAP. Reconciliations of these non-GAAP measures to corresponding GAAP measures are provided below. Discussion of why we utilize these non-GAAP financial measures is provided under "Non-GAAP Financial Measures," in Item 6—Selected Financial Data.

We typically experience the highest level of revenue in the second quarter of each year, which coincides with specific accreditation and regulatory deadlines. See "Management's Discussion and

Analysis of Financial Condition and Results of Operations—Trends and Factors Affecting Our Future Performance—Seasonality."

The following table presents a summary of our cash flow activity for the periods set forth below (in thousands):

Our principal source of liquidity has been our cash, cash equivalents and available-for-sale short-term investments, as well as cash generated by operating activities. As of December 31, 2015, our cash, cash equivalents and short-term investments totaled $728.2 million, of which $614.1 million represented available-for-sale, high grade, domestic debt-securities. Our cash generated from operations has been sufficient to fund our growth, including our capital expenditures. Additionally, our cash generation has allowed us to repurchase certain amounts of our outstanding stock and pay dividends to our stockholders in the amount of $421.0 million from January 1, 2012 through December 31, 2015. In addition, on September 19, 2014, we redeemed $300.0 million of our common stock, at a price per share of $27.01, with proceeds from our Term Loan Facility. Prior to this redemption, we had not historically incurred debt nor have we recently generated liquidity through equity sales.

We believe our current cash, cash equivalents and short-term investments balance, along with expected cash generated by operating activities and availability under our Credit Facilities (defined below) will be sufficient to fund our liquidity needs for the foreseeable future.

On September 19, 2014, we and our subsidiaries entered into a Credit and Guaranty Agreement with a group of lenders including Goldman Sachs Bank USA, as administrative agent (the "Credit Agreement"). The terms of the Credit Agreement provide for credit facilities in the aggregate maximum principal amount of $400.0 million, consisting of a senior unsecured term loan facility in the original principal amount of $300,000 (the "Term Loan Facility") and a senior unsecured revolving credit facility in the maximum principal amount of $100,000 (the "Revolving Credit Facility" and, together with the Term Loan Facility, the "Credit Facilities"). Proceeds of the Revolving Credit Facility may be used for our working capital and general corporate purposes. The obligations under the Credit Facilities are guaranteed by our domestic, wholly owned subsidiaries. The Credit Facilities contain customary affirmative and negative covenants, including limitations on negative pledges and liens. In addition, under the Credit Agreement, we are required to maintain certain minimum liquidity levels ($50.0 million while the Term Loan Facility remains available, or, if the Term Loan Facility has been repaid, $20.0 million), measured at the end of each of our fiscal quarters. In addition, our ability to incur debt is subject to compliance with a 4.00 to 1.00 leverage ratio under certain circumstances. The Credit Agreement also contains certain mandatory prepayment requirements in connection with certain assets sales and customary events of default, including as a result of certain specified change of control events. As of, and during, the year ended December 31, 2015, the Company was in compliance with the financial covenants under the Credit Agreement.

We utilized the entire principal amount of the Term Loan Facility to redeem approximately 8.33% of our Class B common stock on a pro rata basis in September 2014. As of December 31, 2015, the principal amount outstanding under the Term Loan Facility was $281.3 million. The Term Loan Facility has a five-year term. The Term Loan Facility is an amortizing facility and payments of principal and interest are payable quarterly, beginning March 31, 2015. The outstanding principal amount of the Term Loan Facility will amortize as follows: $18.8 million in year one, $15.0 million in year two, $30.0 million in year three, $45 million in year four, and the remaining principal balance in year five. The interest rate for the Term Loan Facility is LIBOR plus 1.25% per annum or the base rate plus 0.25% per annum (at our election).

Borrowings under the Revolving Credit Facility became available, subject to compliance with the terms and conditions set forth in the Credit Agreement, beginning (at our option) after the consummation of our initial public offering. The Revolving Credit Facility is scheduled to mature on March 31, 2020. The interest rate for the Revolving Credit Facility is LIBOR plus 1.25% per annum or the base rate plus 0.25% per annum (at our election).

Cash provided by operating activities consisted of net income adjusted for certain non-cash items, including depreciation and amortization, stock-based compensation, and deferred income taxes, as well as the effect of changes in working capital and other activities.

2015 Compared with 2014. Cash provided by operating activities during the year ended December 31, 2015 was approximately $67.6 million, representing an decrease in cash inflow of approximately $18.0 million compared to the year ended December 31, 2014. The decrease of in cash inflow of approximately $18.0 million was effected by revenue seasonality pushing cash collections to early 2016, and an increase in income tax receivables as a result of tax deductible share-based stock

option exercise activities and a lower effective tax rate. Cash provided by operating activities consisted of net income of approximately $66.1 million, as adjusted for the exclusion of non-cash expenses totaling approximately $20.5 million, which was partially offset by approximately $19.0 million related to the effect of changes in working capital and other balance sheet accounts resulting in cash inflows of approximately $67.6 million.

2014 Compared with 2013. Cash provided by operating activities during the year ended December 31, 2014 was approximately $85.5 million, an increase in cash inflow of approximately $19.5 million compared to the year ended December 31, 2013. Cash provided by operating activities was driven by net income of approximately $65.4 million, as adjusted for the exclusion of non-cash expenses totaling approximately $25.1 million, which was partially offset by approximately $7.7 million related to the effect of changes in working capital and other balance sheet accounts resulting in cash inflows of approximately $85.5 million.

Our primary investing activities consisted of purchases of property and equipment, investments in internally developed capitalized software, and leasehold improvements for our facilities.

2015 Compared with 2014. Cash used in investing activities in the year ended December 31, 2015 was approximately $768.3 million, an increase in cash outflow of approximately $745.7 million compared to the year ended December 31, 2014. The increase in cash outflow primarily resulted from purchases of available-for-sale short term investments, net of sales and maturities of $619.4 million and $122.6 million related to the acquisition of Avalere, net of cash acquired of $4.0 million, and investments in property and equipement as well as capitalized software of approximately $26.4 million.

2014 Compared with 2013. Cash used in investing activities in the year ended December 31, 2014 was approximately $22.6 million, an increase in cash outflow of approximately $3.8 million compared to the year ended December 31, 2013. The slight increase in cash outflow was due to an increase in the investment in capitalized software of approximately $5.5 million, which was partially offset by a decrease in purchases of property and equipment of approximately $1.7 million.

Our primary financing activities have consisted of private purchases and sales of common stock, credit facility borrowings, dividend distributions, and stock option exercises by employees.

2015 Compared with 2014. Cash provided by financing activities during the year ended December 31, 2015 was approximately $652.2 million, an increase of approximately $663.2 million in cash inflow compared to the year ended December 31, 2014. The cash used in financing activities during the year ended December 31, 2015 is primarily comprised of $639.1 million of proceeds from the issuance of common stock in the IPO, $14.7 million of proceeds received from the exercise of stock options, $18.6 million related to excess tax benefits from share-based compensation and was partially offset by repayments of borrowings under our Credit Facilities of $18.8 million and tax payments for equity award issuances of $1.2 million.

2014 Compared with 2013. Cash used in financing activities during the year ended December 31, 2014 was approximately $10.9 million, a decrease of approximately $32.0 million in cash outflow compared to the year ended December 31, 2013. The cash used in financing activities during the year ended December 31, 2014 is primarily comprised of $309.1 million for the repurchase of common stock, and $2.9 million for the payment of previously declared dividends, partially offset by $300.0 million from proceeds of the Term Loan and $0.7 million from the exercise of employee stock options.

We do not have any off-balance sheet arrangements and did not have any such arrangements during the years ended December 31, 2015, 2014, and 2013.

Our principal commitments consist of obligations under our senior unsecured term loan facility (see Note 10 of the Consolidated Financial Statements), and our operating leases for equipment, office space, and co-located data center facilities. The following table summarizes our future payments in cash, excluding the effects of time value, on contractual obligations by period as of December 31, 2015.

We have cash interest requirements, due on the Credit Facilities, payable at variable rates, that are not included in the table above.

Our existing operating lease agreements may provide us with the option to renew. Our future operating lease obligations would change if we entered into additional operating lease agreements and if we exercised renewal options.

Contractual obligations represent future cash commitments and liabilities under agreements with third parties, and exclude purchase orders for goods and services. Purchase orders are not included in the table above. Our purchase orders represent authorizations to purchase rather than legally binding agreements. The contractual commitment amounts in the table above are associated with agreements that are legally binding and enforceable, and that specify all significant terms, including fixed or minimum services to be used, fixed, minimum or variable price provisions and the approximate timing of the transaction.

We prepare our consolidated financial statements in accordance with GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect our reported amounts of assets, liabilities, revenue and expenses, as well as related disclosures. To the extent that there are material differences between these estimates and actual results, our financial condition or operating results would be affected. We base our estimates on past experience and other assumptions that we believe are reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. We refer to accounting estimates of this type as critical accounting policies and estimates, which we discuss further below.

Our significant accounting policies are described in note 2, "Summary of Significant Accounting Policies", of the notes to our consolidated financial statements, included under Item 15 of this annual report on Form 10-K. The following are the accounting policies that we believe involve a greater degree of judgement and complexity and are the most critical to aid in fully understanding and evaluating our consolidated financial condition and results of operations.

We recognize revenue when it is realized (or realizable) and earned (i.e., when services have been rendered or delivery of applicable deliverables has occurred). This occurs when persuasive evidence of an arrangement exists, the product or service has been performed or delivered, fees are fixed or determinable, and collection is reasonably assured. When collectability is not reasonably assured, revenue is recognized when cash is collected. Cash collections and invoices generated in excess of revenue recognized are recorded as deferred revenue until the revenue recognition criteria are met.

We have primarily derived our revenue from sales of our data analytics and data-driven intervention platform services. We allocate revenue to our data-driven analytics and data-driven intervention platform services using the relative selling price method. We have generally been unable to establish vendor-specific objective evidence of fair value and, while we continually seek third-party evidence of fair value, meaningful data have generally been unavailable as our services are unique and visibility into our competitors' pricing is unavailable. As a result, we use our best estimate of selling price to allocate arrangement consideration to its contractual service elements.

We have determined an estimated selling price by considering several external and internal factors, including, but not limited to pricing practices, margin objectives, competition, customer demand, internal costs, and overall economic trends. Generally, the best estimate of selling price is consistent with the contractual arrangement fee for each element.

Revenue is recognized as cloud-based data analytics and data-driven intervention services are performed and information is delivered to clients, which generally align with our right to invoice our clients. Cloud-based data analytics services are considered performed when gaps in care, quality, data integrity, or financial performance, and summarized key analytics and benchmarking analytics reports are delivered to its clients, provided that all contractual performance requirements and other revenue recognition criteria are met. Cloud-based data-driven intervention services are considered performed upon completion, provided that all contractual performance requirements and other revenue recognition criteria are met.

The Company also generates revenues from data-driven advisory services. The Company recognizes revenue for data-driven advisory services when persuasive evidence of an arrangement exists, services have been rendered, the contract price is fixed or determinable, and collectability is reasonably assured. The Company enters into arrangements for data-driven advisory services under time and materials, fixed-price, or retainer based contracts. Revenue for time and material contracts is recognized based upon contractually agreed upon billing rates applied to direct labor hours expended plus the costs of other items used in the performance of the contract. Revenue on certain fixed-price contracts is recognized using the proportional performance method. Performance is measured based on the ratio of labor hours incurred to total estimated labor hours. Revenues under certain other fixed-price and retainer based contracts are recognized ratably over the contract period or upon contract completion. Invoices to clients are generated in accordance with the terms of the applicable contract, which may not be directly related to the performance of services. Unbilled receivables are invoiced based upon the achievement of specific events as defined by each contract including deliverables and timetables. Unbilled receivables, if any, are classified as a current asset. Advanced billings to clients in excess of revenue earned are recorded as deferred revenue until the aforementioned revenue recognition criteria are met.

We also enter into multiple-element software arrangements, which are recognized under ASC 985-605, Software Revenue Recognition, when a software subscription license is provided to customers. Under these arrangements, we provide post-contract support, including help desk support and unspecified upgrades. Vendor-specific objective evidence of fair value has not been established for maintenance as maintenance is not renewed separately from the license fees. As a result, under these subscription software license agreements, we recognize revenue from the license of software ratably

over the life of the agreement. We begin to recognize revenue upon execution of a signed agreement and delivery of the software, provided that the software license fees are fixed and determinable, and collection of the resulting receivable is reasonably assured.

Certain of our arrangements entitle a client to receive a refund if we fail to satisfy contractually specified performance obligations. The refund is limited to a portion or all of the consideration paid. In this case, revenue is recognized when any and all performance obligations are satisfied.

We maintain an allowance, charged to revenue, which reflects our estimated future billing adjustments resulting from client concessions or resolutions of billing disputes.

All stock-based awards, including employee stock option, RSU and RSA grants, are measured and recognized in the financial statements at fair value as of the grant date in accordance with ASC 718, Compensation—Stock Compensation. We recognize stock-based compensation expense, net of estimated forfeitures based on historical and anticipated turnover data, using the straight-line basis over the service period of the applicable award, which is generally five years.

We estimate the fair value of each stock option award on the grant date using the Black-Scholes option pricing model. The Black-Scholes option-pricing model requires the input of estimates, including the fair market value of our common stock, the expected volatility of the price of our common stock, expected life, the risk free interest rate, and the expected dividend yield of our common stock. The input assumptions used in the Black-Scholes option-pricing model represent management's best estimates. These estimates involve inherent uncertainties and the application of management's judgment. If factors change and different assumptions are used, the amount of stock-based compensation expense could be materially different in the future.

We estimate the expected volatility of our stock options by using data for several unrelated public companies within our industry that are considered to be comparable to our company and for which historical information was available. The average expected term was determined under the simplified calculation as provided by the SEC Staff's Accounting Bulletin No. 107, Share-Based Payment, which is the mid-point between the vesting date and the end of the contractual term. We determine the risk-free interest rate by reference to the U.S. Treasury yield curve rates with the remaining term commensurate with the expected life assumed at the date of grant. The dividend yield assumption of zero is based upon the fact that we do not have a formal dividend payment policy, we do not intend to continue to pay cash dividends on our common stock in the future, and, to the extent we pay dividends in the future, there is no assurance that any such dividends will be comparable to those previously declared. We estimate the forfeiture rate of our stock-based awards based on historical experience and adjustments are made annually to reflect actual forfeiture experience. We will continue to use judgment in evaluating the assumptions related to our stock-based compensation on a prospective basis. As we continue to accumulate additional data related to our common stock, we may have refinements to our estimates, which could materially impact our future stock-based compensation expense.

We estimate the fair value of each RSU and RSA based on the fair market values of the underlying common stock on the dates of grant. RSUs are share awards that, upon vesting, will deliver to the holder shares of the Company's common stock. RSAs are shares of the Company's common stock that are reserved in the grantee's name upon grant which will be delivered to the holder upon vesting.

We account for income taxes using the asset and liability approach, which requires the recognition of deferred tax assets and liabilities related to the expected future tax consequences of events that have

been recognized between financial reporting and income tax reporting. We measure deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.

We make estimates, assumptions and judgments to determine our provision for income taxes and also for deferred tax assets and liabilities and any valuation allowances recorded against our deferred tax assets. We assess the likelihood that our deferred tax assets will be recovered from future taxable income and, to the extent we believe that recovery is not likely, we establish a valuation allowance.

We have adopted ASC 740-10, Accounting for Uncertainty in Income Taxes, that prescribes a recognition threshold of more-likely- than-not, and a measurement attribute for all tax positions taken or expected to be taken on a tax return, in order for those positions to be recognized in the financial statements. We continually review tax laws, regulations and related guidance in order to properly record any uncertain tax liability positions. We adjust these reserves in light of changing facts and circumstances.

Goodwill represents the excess of acquisition costs over the fair value of tangible net assets and identifiable intangible assets of the businesses acquired. Goodwill is not amortized. Goodwill is subject to impairment testing annually as of December 31^st, or whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. The Company's impairment tests are based on a structure consisting of a single operating segment and two reporting units. During 2015, the Company performed a qualitative assessment for our reporting units, during this assessment, qualitative factors were first assessed to determine whether it was more likely than not that the fair value of the reporting units were less than their carrying amounts. Qualitative factors that were considered included, but were not limited to, macroeconomic conditions, industry and market conditions, company specific events, changes in circumstances, after tax cash flows and market capitalization. Based on the Company's annual impairment evaluation performed as of December 31, 2015, the Company concluded that there were no indicators of impairment and therefore it was more likely than not that the fair value of the goodwill exceeded its carrying amount, for each reporting unit, and there was no reason to perform the two-step impairment test. The two-step impairment test compares a reporting unit's carrying value to its fair value. If the fair value of the reporting unit exceeds the carrying value of the net assets, including goodwill assigned to that reporting unit, goodwill is not impaired. If the carrying value of the reporting unit's net assets, including goodwill, exceeds the fair value of the reporting unit, then the Company will determine the implied fair value of the reporting unit's goodwill. If the carrying value of a reporting unit's goodwill exceeds its implied fair value, then an impairment loss is recorded for the difference between the carrying amount and the implied fair value of the goodwill. The Company completed its annual impairment test as of December 31, 2014 which resulted in no impairment of goodwill. Our 2014 impairment test was based on a single operating segment and reporting unit structure. The fair value of our reporting unit significantly exceeded its respective carrying value at December 31, 2014. Accordingly, we did not record any goodwill impairments for any period presented.

We are an "emerging growth company," as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and, therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

Recently issued accounting standards and their expected impact, if any, are discussed in note 2, "Summary of Significant Accounting Policies", of the notes to our consolidated financial statements, included under Item 15 within this annual report on Form 10-K.

Market risk includes risks that arise from changes in interest rates, equity prices and other market changes that affect market sensitive instruments.

Our primary market risk exposure is related to changes in interest rates on our variable rate debt and marketable securities.

Our variable rate debt includes our Term Loan Facility and our Revolving Credit Facility. As of December 31, 2015, we had $281.3 million outstanding under our Term Loan Facility at an effective interest rate of 1.4%. As a result, if market interest rates were to increase by 1.0%, or 100 basis points, interest expense would decrease future earnings and cash flows, net of estimated tax benefits, by approximately $1.7 million annually, assuming that we do not enter into contractual hedging arrangements. As of December 31, 2015, there was no balance outstanding on the Revolving Credit Facility.

We had cash, cash equivalents and short-term investments totaling approximately $728.2 million as of December 31, 2015. This amount was invested primarily in marketable securities including corporate notes and bonds, U.S. agency obligations, commercial paper, U.S. treasury securities, certificates of deposit and money market funds. The cash and cash equivalents are held for working capital purposes. Our investments are made for capital preservation purposes. We do not enter into investments for trading or speculative purposes.

Our cash equivalents and our short-term investments are subject to market risk due to changes in interest rates, which could affect our results of operations. Fixed rate securities may have their market value adversely affected due to a rise in interest rates, while floating rate securities may produce less income than expected if interest rates fall. Due in part to these factors, our future investment income may fluctuate due to changes in interest rates or we may suffer losses in principal if we are forced to sell securities that decline in market value due to changes in interest rates. However because we classify our marketable securities as "available for sale," no realized gains or losses are recognized due to changes in interest rates unless such securities are sold prior to maturity or declines in fair value are determined to be other-than-temporary.

An immediate increase of 100-basis points in interest rates would have resulted in an approximate $4.6 million market value reduction in our investment portfolio as of December 31, 2015. An immediate decrease of 100-basis points in interest rates would have increased the market value by approximately $10.6 million as of December 31, 2015. This estimate is based on a sensitivity model that measures market value changes when changes in interest rates occur. Fluctuations in the value of our investment securities caused by a change in interest rates (gains or losses on the carrying value) are recorded in accumulated other comprehensive income, and are realized only if we sell the underlying securities.

Our consolidated financial statements and supplementary data are included as a separate section of this Annual Report on Form 10-K commencing on page F-1 and are incorporated herein by reference.

The supplementary financial information required by this Item 8 is included in Item 7 under the caption "Quarterly Results of Operations," which is incorporated herein by reference.

Item 9. Changes and Disagreements with Accountants on Accounting and Financial Disclosure.

Our management, with the participation of our chief executive officer ("CEO") and chief financial officer ("CFO"), has evaluated the effectiveness of our disclosure controls and procedures, (as defined in Rules 13a- 15(e) and 15d- 15(e) under the Exchange Act), as of the end of the period covered by this Annual Report on Form 10-K. Based on such evaluation, our CEO and CFO have concluded that, as of December 31, 2015, our disclosure controls and procedures were designed at a reasonable assurance level to ensure that material information relating to Inovalon Holdings, Inc., including its consolidated subsidiaries, is made known to our CEO and CFO by others within those entities, particularly during the period in which this report was being prepared and that our disclosure controls and procedures were effective in providing reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure.

Our management, with the participation of our CEO and CFO, is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act). Our management conducted an assessment of the effectiveness of our internal control over financial reporting based on the criteria established in "Internal Control—Integrated Framework" (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on that assessment, our management has concluded that our internal control over financial reporting was effective as of December 31, 2015.

Our management, including our CEO and CFO, believes that our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving their objectives and are effective at the reasonable assurance level. However, our management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the

inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

This Annual Report on Form 10-K does not include an attestation report of the Company's registered public accounting firm due to a transition period established by rules of the SEC for newly public companies and because we are an Emerging Growth Company.

There have been no changes in the Company's internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the three months ended December 31, 2015 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

On September 1, 2015, we completed our acquisition of Avalere and effective from that date, we began integrating Avalere into our existing control procedures. We do not currently anticipate any changes to materially affect our internal control over financial reporting as a result of the integration of Avalere.

21.1	*	Subsidiaries of the Registrant.

Pursuant to the requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorized.

Pursuant to the requirements of the Securities Exchange Act of 1934, this report has been signed below by the following persons on behalf of the Registrant and in the capacities and on the dates indicated.

To the Board of Directors and Stockholders of
Inovalon Holdings, Inc.
Bowie, Maryland

We have audited the accompanying consolidated balance sheets of Inovalon Holdings, Inc. and subsidiaries (the "Company") as of December 31, 2015 and 2014, and the related consolidated statements of operations, comprehensive income, stockholders' equity (deficit), and cash flows for each of the three years in the period ended December 31, 2015. Our audits also included the financial statement schedule listed in the Index at Item 15. These financial statements and financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on the financial statements and financial statement schedule 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 consolidated financial statements present fairly, in all material respects, the financial position of Inovalon Holdings, Inc. and subsidiaries as of December 31, 2015 and 2014, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2015, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

Inovalon Holdings, Inc.

1. NATURE OF OPERATIONS(in thousands, except share and per share amounts)

Inovalon Holdings, Inc., (the "Company"), is a leading technology company that combines advanced cloud-based data analytics and data-driven intervention platforms to achieve meaningful impact in clinical and quality outcomes, utilization, and financial performance across the healthcare landscape. The value that the Company delivers to its clients is achieved by turning data into insights and those insights into action. Through the Company's large proprietary datasets, advanced integration technologies, sophisticated predictive analytics, and deep subject matter expertise, the Company delivers seamless, end-to-end platforms that bring the benefits of big data and large-scale analytics to the point of care. The Company's analytics platforms identify gaps in care, quality, data integrity, and financial performance, in its clients' datasets. The Company's data-driven intervention platforms enable clients to take the insights derived from the analytics and implement unique, patient-level solutions, drive impact and enhance patient engagement.

On September 17, 2014, Inovalon, Inc. implemented a holding company reorganization, pursuant to which Inovalon Holdings, Inc. (together with its wholly owned subsidiaries, Inovalon or the Company) became the new parent company of Inovalon, Inc. and Inovalon, Inc. became the direct, wholly owned subsidiary of the Company. The Company was incorporated in the state of Delaware on September 11, 2014. Inovalon, Inc. was incorporated in the state of Delaware on November 18, 2005. The impact of the holding company reorganization is retrospectively presented in the accompanying consolidated financial statements by recognizing the entity as Inovalon Holdings, Inc. The consolidated balance sheet and consolidated statement of stockholders' equity (deficit) depict the newly authorized classes of stock. Additionally, earnings per share is calculated based upon the newly created Class B common stock (refer to Notes 4 and 13 for additional information). On January 14, 2015, the Company's board of directors approved a five-for-one stock split of the Company's Class A common stock and Class B common stock. Effective January 16, 2015 the Company amended its certificate of incorporation to give effect to the stock split and to change the Company's authorized common equity capital to 900,000,000 shares of common stock, 750,000,000 shares of Class A common stock, and 150,000,000 shares of Class B common stock, par value $0.000005 per share. All share data included in these financial statements give retroactive effect to the stock split and related amendment to the Company's certificate of incorporation.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES(in thousands, except years)

Principles of Consolidation—The accompanying consolidated financial statements include the accounts of Inovalon Holdings, Inc. and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Basis of Presentation and Use of Estimates—These consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles ("GAAP"). The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenue and expenses during the reported period.

Significant estimates made by management include, but are not limited to: revenue recognition, specifically selling prices associated with the individual elements in multiple element arrangements; accounts receivable allowances; estimates of the fair value of the Company's common stock and the related estimates of the fair value of stock-based awards; fair value of intangibles and goodwill;

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES(in thousands, except years) (Continued)

depreciable lives of property, equipment and capitalized software; and useful lives of intangible assets. Actual results could differ from management's estimates, and such differences could be material to the Company's consolidated financial position and results of operations.

Cash and Cash Equivalents—Cash and cash equivalents consist of highly liquid investments with an original maturity of three months or less at the time of purchase, and demand deposits with financial institutions.

Short-term investments—Our portfolio of short-term investments consists of investment grade debt securities. The Company classifies short-term investments as available-for-sale at the time of purchase and reevaluates such classification as of each balance sheet date. All short-term investments are recorded at estimated fair value. Unrealized gains and losses for available-for-sale securities are included in accumulated other comprehensive loss, a component of stockholders' equity. The Company evaluates its investments to assess whether those with unrealized loss positions are other than temporarily impaired. The Company considers impairments to be other-than-temporary if they are related to deterioration in credit risk, if it is more likely than not that the Company will be required to or if the Company intends to sell the securities before the recovery of their cost basis. Realized gains and losses and declines in value judged to be other than temporary are determined based on the specific identification method and are reported as components of other income and (expenses), in the consolidated statements of operations. Interest, amortization of premiums, and accretion of discount on short-term investments classified as available for sale are included as a component of interest income, in the consolidated statements of operations. There were no other-than-temporary impairments during 2015.

The Company may sell short-term investments at any time, without significant penalty, for use in current operations or for other purposes, even if the short-term investments have not yet reached maturity. As a result, the Company classifies these investments, including securities with maturities beyond 12 months, as current assets in the accompanying consolidated balance sheets. Gains or losses realized from the sale of securities are reclassified out of other comprehensive income (loss) into earnings using the specific identification method.

Concentrations of Credit Risk—Accounts receivable and cash and cash equivalents subject the Company to its highest potential concentrations of credit risk. Although the Company deposits its cash and cash equivalents with multiple financial institutions, the Company's deposits may exceed federally insured limits. The Company has not experienced any losses on cash and cash equivalent accounts to date, and management believes the Company is not exposed to any significant credit risk related to cash and cash equivalents.

The Company sells services to clients without requiring collateral, based on an evaluation of the client's financial condition. Exposure to losses on receivables is principally dependent on each client's financial condition. The Company monitors its exposure for credit losses and maintains allowances for anticipated losses.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES(in thousands, except years) (Continued)

Revenue from significant clients, those representing 10% or more of total revenue for the respective periods, is summarized as follows:

Accounts receivable from significant clients, those representing 10% or more of total accounts receivable for the dates noted, is summarized below:

Accounts Receivable and Allowances—Accounts receivable consists primarily of amounts due to the Company from its normal business activities. The Company provides an allowance for estimated losses resulting from the failure of clients to make required payments (credit losses) and a sales allowance for estimated future billing adjustments resulting from client concessions or resolutions of billing disputes. The provision for sales allowances are charged against revenue while credit losses are recorded in general and administrative expenses.

Fair Value Measurements—The Company applies the Accounting Standards Codifications, or ASC, 820-10, Fair Value Measurements and Disclosures, ASC 820-10. ASC 820-10 defines fair value, establishes a fair value hierarchy for assets and liabilities measured at fair value, and expands required disclosures about fair value measurements. This guidance requires the Company to classify and disclose assets and liabilities measured at fair value on a recurring basis, as well as fair value measurements of assets and liabilities measured on a nonrecurring basis in periods subsequent to initial measurement, in a three-tier fair value hierarchy as described below.

The guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES(in thousands, except years) (Continued)

unobservable inputs. The guidance describes three levels of inputs that may be used to measure fair value:

Financial instruments are defined as cash, or other financial instruments to a third party. The carrying amounts of accounts receivable and other current assets, accounts payable and accrued liabilities approximate fair value due to their short-term nature. The Company's Credit Facilities (as defined in Note 9 below) approximate fair value because of their floating rate structure.

Property, Equipment and Capitalized Software, net—Property and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation and amortization on property, leasehold improvements, equipment, and software is computed on a straight-line basis over the estimated useful lives of the assets, as follows:


		Useful Life
Office and computer equipment		3 - 5 years
Purchased software		5 years
Capitalized software		3 - 5 years
Furniture and fixtures		7 years
Building		40 years
Leasehold improvements		*
Assets under capital leases		*

Expenses for repairs and maintenance that do not extend the life of property and equipment are charged to expense as incurred. Expenses for major renewals and betterments, which significantly extend the useful lives of existing property and equipment, are capitalized and depreciated. Upon retirement or disposition of property and equipment, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized.

In accordance with ASC 350-40, Internal-use Software, the Company capitalizes certain software development costs while in the application development stage related to software developed for internal use. All other costs to develop software for internal use, either in the preliminary project stage or post implementation stage, are expensed when incurred. Software development costs are amortized on a straight-line basis over a three to five year period, which management believes represents the useful life of these capitalized costs.

In accordance with ASC 985-20, Software to be Sold, Leased, or Marketed, certain software development costs are expensed as incurred until technological feasibility has been established.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES(in thousands, except years) (Continued)

Thereafter, all software development costs incurred through the software's general release date are capitalized and subsequently reported at the lower of amortized cost or net realizable value. Capitalized costs are amortized based on current and expected future revenue for each software solution with minimum annual amortization equal to the straight-line amortization over the estimated economic life, which is typically over a three to five year period, of the solution.

Intangible Assets—Intangible assets consist of acquired technology, including developed and core technology, databases, trade names, and customer relationships. Intangible assets are initially recorded at fair value and amortized on a straight line basis over their estimated useful lives. Acquired intangible assets are being amortized over the following periods:


		Useful Life
Proprietary software technology		2 - 10 years
Trademark		5 - 10 years
Database		10 years
Customer relationships		4 - 15.75 years
Non-compete agreements		Contractual term

On an annual basis, the Company reviews its intangible assets for impairment based on estimated future undiscounted cash flows attributable to the assets. In the event such cash flows are not expected to be sufficient to recover the recorded value of the assets, the assets are written down to their net realizable values. There were no impairment charges on intangible assets for the years ended December 31, 2015 and 2014.

Goodwill—Goodwill represents the excess of acquisition costs over the fair value of tangible net assets and identifiable intangible assets of the businesses acquired. Goodwill is not amortized. Goodwill is subject to impairment testing annually as of December 31^st, or whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. The Company's impairment tests are based on a structure consisting of a single operating segment and two reporting units. During 2015, the Company performed a qualitative assessment for our reporting units, during this assessment, qualitative factors were first assessed to determine whether it was more likely than not that the fair value of the reporting units were less than their carrying amounts. Qualitative factors that were considered included, but were not limited to, macroeconomic conditions, industry and market conditions, company specific events, changes in circumstances, after tax cash flows and market capitalization. Based on the Company's annual impairment evaluation performed as of December 31, 2015, the Company concluded that there were no indicators of impairment and therefore it was more likely than not that the fair value of the goodwill exceeded its carrying amount, for each reporting unit, and there was no reason to perform the two-step impairment test. The two-step impairment test compares a reporting unit's carrying value to its fair value. If the fair value of the reporting unit exceeds the carrying value of the net assets, including goodwill assigned to that reporting unit, goodwill is not impaired. If the carrying value of the reporting unit's net assets, including goodwill, exceeds the fair value of the reporting unit, then the Company will determine the implied fair value of the reporting unit's goodwill. If the carrying value of a reporting unit's goodwill exceeds its implied fair value, then an impairment loss is recorded for the difference between the carrying amount and the implied fair value of the goodwill. The Company completed its annual impairment test as of December 31, 2014 which resulted in no impairment of goodwill. Our 2014 impairment test was based

on a single operating segment and reporting unit structure. The fair value of our reporting unit significantly exceeded its respective carrying value at December 31, 2014. Accordingly, we did not record any goodwill impairments for any period presented.

Valuation of Long-Lived Assets—The Company reviews long- lived assets for events or changes in circumstances that would indicate potential impairment. If the Company determines that an asset may not be recoverable, an impairment charge is recorded. A $255 impairment charge on long-lived assets was recognized in general as administrative expenses for the year ended December 31, 2014. There were no impairment charges on long-lived assets for the years ended December 31, 2015 and 2013.

Revenue Recognition—The Company recognizes revenue when it is realized (or realizable) and earned (i.e., when services have been rendered or delivery of applicable deliverables has occurred). This occurs when persuasive evidence of an arrangement exists, the product or service has been performed or delivered, fees are fixed or determinable, and collection is reasonably assured. When collectability is not reasonably assured, revenue is recognized when cash is collected. Cash collections and invoices generated in excess of revenue recognized are recorded as deferred revenue until the revenue recognition criteria are met.

The Company primarily derives its revenue from multiple-element arrangement sales of its cloud-based data analytics and data-driven intervention platform services. Revenue from these multiple element arrangements are recognized in accordance with ASC 605-25, Revenue Recognition—Multiple Element Arrangements. The Company allocates revenue to its cloud-based data analytics and data-driven intervention platform services using the relative selling price method. The Company has generally been unable to establish vendor-specific objective evidence of fair value, and while the Company routinely seeks third party evidence of fair value, meaningful data has generally been unavailable as the Company's services are unique and visibility into competitors pricing is unavailable. As a result, the Company uses its best estimate of selling price to allocate arrangement consideration to its contractual service elements.

The Company has determined a best estimate of selling price by considering several external and internal factors including, but not limited to, pricing practices, margin objectives, competition, customer demand, internal costs, and overall economic trends.

Generally, the best estimate of selling price is consistent with the contractual arrangement fee for each element.

Revenue is recognized as cloud-based data analytics and data-driven intervention services are performed and information is delivered to clients, which generally align with the Company's right to invoice its clients. Cloud- based data analytics services are considered performed when gaps in care, quality, data integrity, or financial performance, and summarized key analytics and benchmarking analytics reports are delivered to its clients, provided that all contractual performance requirements and other revenue recognition criteria are met. Cloud-based data-driven intervention services are considered performed upon completion, provided that all contractual performance requirements and other revenue recognition criteria are met.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES(in thousands, except years) (Continued)

The Company enters into arrangements for data-driven advisory services under time and materials, fixed-price, or retainer based contracts. Revenue for time and material contracts is recognized based upon contractually agreed upon billing rates applied to direct labor hours expended plus the costs of other items used in the performance of the contract. Revenue on certain fixed-price contracts is recognized using the proportional performance method. Performance is measured based on the ratio of labor hours incurred to total estimated labor hours. Revenues under certain other fixed-price and retainer based contracts are recognized ratably over the contract period or upon contract completion. Invoices to clients are generated in accordance with the terms of the applicable contract, which may not be directly related to the performance of services. Unbilled receivables are invoiced based upon the achievement of specific events as defined by each contract including deliverables and timetables. Unbilled receivables, if any, are classified as a current asset. Advanced billings to clients in excess of revenue earned are recorded as deferred revenue until the aforementioned revenue recognition criteria are met.

The Company also enters into multiple-element software arrangements, which are recognized under ASC 985-605, Software Revenue Recognition, when software subscription licenses are provided to clients. Under these arrangements, the Company provides post-contract support, or PCS, including help desk support and unspecified upgrades. Vendor-specific objective evidence of fair value has not been established for PCS as PCS is not renewed separately from the license fees. As a result, under these subscription software license agreements, the Company recognizes revenue from the license of software ratably over the life of the agreement. The Company begins to recognize revenue upon execution of a signed agreement and delivery of the software, provided that the software license fees are fixed and determinable, and collection of the resulting receivable is reasonably assured.

Certain of the Company's arrangements entitle a client to receive a refund if the Company fails to satisfy contractually specified performance obligations. The refund is limited to a portion or all of the consideration paid. In this case, revenue is recognized when performance obligations are satisfied.

The Company maintains an allowance, charged to revenue, which reflects the Company's estimated future billing adjustments resulting from client concessions or resolutions of billing disputes.

Cost of Revenue—Cost of revenue consists primarily of expenses for employees who provide direct revenue-generating services to clients, including salaries, benefits, discretionary incentive bonus compensation, employment taxes, equity compensation costs, and severance. Cost of revenue also includes expenses associated with the integration and verification of data and other service costs incurred to fulfill the Company's revenue contracts. Cost of revenue does not include allocated amounts for occupancy expense and depreciation and amortization.

Research and Development—Research and development expenses consist primarily of employee-related costs. All such costs are expensed as incurred, except for certain internal use software development costs that are capitalized. Research and development excludes any allocation of occupancy expense, depreciation and amortization.

Selling and Marketing—Sales and marketing expense consists primarily of employee-related expenses including salaries, benefits, discretionary incentive compensation, employment taxes, severance and equity compensation costs for employees engaged in sales, sales support, business development, and marketing. Sales and marketing expense also includes operating expenses for marketing programs,

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES(in thousands, except years) (Continued)

research, trade shows and brand messages, and public relations costs. Sales and marketing expense excludes any allocation of occupancy expense, depreciation and amortization.

General and Administrative—General and administrative expense consists primarily of employee-related expenses including salaries, benefits, discretionary incentive compensation, employment taxes, severance and equity compensation costs, for employees who are responsible for management information systems, administration, human resources, finance, legal, and executive management. General and administrative expense also includes occupancy expenses (including rent, utilities, communications, and facilities maintenance), professional fees, consulting fees, insurance, travel, and other expenses. General and administrative expense excludes any allocation of depreciation and amortization.

Segments—The Company operates its business as one operating segment. The Company develops cloud-based data analytics and data-driven intervention platforms and provides related services to its clients in order to achieve meaningful insight and improvement in clinical and quality outcomes, utilization, and financial performance. The Company derives substantially all of its revenue from the sale and support of one group of similar products and related services—proprietary datasets, advanced integration technologies, sophisticated predictive analytics, and deep subject matter expertise that enable the Company to provide seamless, end-to-end platforms that bring the benefits of big data and large-scale analytics to clients. Operating segments are defined as components of an enterprise for which separate financial information is available and is evaluated regularly by the Company's chief operating decision maker ("CODM"), or decision-making group, in deciding how to allocate resources and in assessing performance. In the process of allocating resources and assessing performance, the Company's CODM, its chief executive officer, reviews financial information presented on a consolidated basis.

Income Taxes—The Company accounts for income taxes in accordance with Accounting Standards Codification ASC 740, Income Taxes, which prescribes the use of the asset and liability approach to the recognition of deferred tax assets and liabilities related to the expected future tax consequences of events that have been recognized in the Company's financial statements or income tax returns. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Valuation allowances are established, when necessary, to reduce deferred tax assets when it is more likely than not that a portion or all of a given deferred tax asset will not be realized. In accordance with ASC 740, income tax expense includes (i) deferred tax expense, which generally represents the net change in the deferred tax asset or liability balance during the period plus any change in valuation allowances and (ii) current tax expense, which represents the amount of tax currently payable to or receivable from a taxing authority plus amounts accrued for expected tax contingencies (including both tax and interest). ASC 740 prescribes a recognition threshold of more-likely-than-not, and a measurement attribute for all tax positions taken or expected to be taken on a tax return, in order for those positions to be recognized in the financial statements. The Company continually reviews tax laws, regulations and related guidance in order to properly record any uncertain tax liability positions. The Company adjusts these reserves in light of changing facts and circumstances.

Stock-Based Compensation—All stock-based awards, including employee stock option grants, restricted stock unit ("RSU") grants, and restricted stock awards ("RSA"), are recorded at fair value as

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES(in thousands, except years) (Continued)

of the grant date in accordance with ASC 718, Compensation—Stock Compensation, and recognized in the statement of operations over the service period of the applicable award using the straight-line method.

The Company determines the fair value of its stock option awards on the date of grant, using the Black-Scholes option pricing model. The Company estimates the number of share-based awards that are expected to be forfeited based on historical and anticipated turnover data at the date of grant and revises the estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The assumptions used in calculating the fair value of share-based awards represent management's best estimates.

The Company measures RSUs and RSAs that vest upon satisfaction of a service condition, or a liquidity condition if such a condition is applicable, based on the fair market values of the underlying common stock on the dates of grant. RSUs are share awards that, upon vesting, will deliver to the holder shares of the Company's common stock. Compensation expense is recognized based upon the satisfaction of the requisite service and or liquidity condition as of that date, following the straight-line method, net of estimated forfeitures. The Company estimates future forfeitures at the date of grant and revises the estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Treasury Stock—The Company records treasury stock activities under the cost method whereby the cost of the acquired stock is recorded as treasury stock. The Company's accounting policy upon the formal retirement of treasury stock is to deduct the par value from common stock and to reflect any excess of cost over par value as a reduction to additional paid-in capital (to the extent created by previous issuances of the shares) and then retained earnings.

Deferred Rent—Deferred rent consists of rent escalation payment terms, tenant improvement allowances and other incentives received from landlords related to the Company's operating leases for its facilities. Rent escalation represents the difference between actual operating lease payments due and straight-line rent expense, which is recorded by the Company over the term of the lease, including any construction period. The excess is recorded as a deferred credit in the early periods of the lease, when cash payments are generally lower than straight-line rent expense, and is reduced in the later periods of the lease when payments begin to exceed the straight-line expense. Tenant allowances from landlords for tenant improvements are generally comprised of cash received from the landlord as part of the negotiated terms of the lease or reimbursements of moving costs. These cash payments are recorded as deferred rent from landlords and are amortized as a reduction of periodic rent expense, over the term of the applicable lease.

Deferred Initial Public Offering ("IPO") Issuance Costs—The Company capitalizes IPO costs, which primarily consist of direct incremental legal and accounting fees relating to the IPO. The IPO issuance costs will be offset against IPO proceeds in periods following the consummation of the offering. As of December 31, 2014, there was $2,888 deferred as prepaid expenses and other current assets, and no amounts were deferred at December 31, 2015.

In May 2014, the Financial Accounting Standards Board ("FASB") issued updated guidance on revenue from contracts with customers. This revenue recognition guidance supersedes existing

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES(in thousands, except years) (Continued)

GAAP guidance, including most industry-specific guidance. The core principle is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance identifies five steps to apply in achieving this principle. On July 9, 2015, the FASB approved a one year deferral of the effective date of ASU 2014-09 to January 1, 2018. ASU 2014-09 may be applied either retrospectively or through the use of a modified-retrospective method. The Company is currently evaluating both methods of adoption as well as the effect ASU 2014-09 will have on the Company's consolidated financial position, results of operations, cash flows and financial disclosures, including whether the Company elects retrospective, or modified retrospective, method adoption. The Company currently expects the most significant impact arising from the adoption of ASU 2014-09 to result in additional disclosures related to qualitative and quantitative information concerning the nature, amount, timing, and any uncertainty of revenue and cash flows from contracts with customers.

In June 2014, the FASB issued ASU 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide a Performance Target Could Be Achieved After the Requisite Service Period, requiring that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. The amendments in this guidance are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. The Company does not expect the adoption of this pronouncement to have an impact on our financial statements as this guidance mirrors our existing policy for such share-based awards.

In September 2015, the FASB issued ASU No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments ("ASU No. 2015-16"). ASU No. 2015-16 requires, for business combinations, that the acquirer record, in the same period's financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. ASU No. 2015-16 is effective for fiscal years beginning after December 15, 2015, with early adoption permitted. The Company early adopted the provisions of ASU No. 2015-16 during the fourth quarter of 2015. Under the previous guidance, an acquirer must recognize adjustments to provisional amounts during the measurement period retrospectively (i.e. as if the accounting for the business combination had been completed at the acquisition date). That is, the acquirer must revise comparative information on the income statement and balance sheet for any prior periods affected. Under ASU 2015-16, acquirers must recognize measurement-period adjustments in the period in which they determine the amounts, including the effect on earnings of any amounts they would have recorded in previous periods if the accounting had been completed at the acquisition date. The amendments in ASU 2015-16 require an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earning by line item that would have been in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 did not change the criteria for determining whether an adjustment qualifies as a measurement-period adjustment and does not change the length of the measurement period. See Note 3 for the Company's disclosures related to the early adoption of ASU 2015-16.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES(in thousands, except years) (Continued)

In November 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-17, Balance Sheet Classification of Deferred Taxes, which will require entities to present all deferred tax assets ("DTAs") and deferred tax liabilities ("DTLs") as non-current on the balance sheet. This guidance is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted, and entities may choose whether to adopt this update prospectively or retrospectively. We have elected to early adopt ASU 2015-17 and change our method of classifying DTAs and DTLs as either current or non-current to classifying all DTAs and DTLs as non-current, and have chosen to apply a prospective method. Prior balance sheets were not retrospectively adjusted.

On September 1, 2015, (the "Acquisition Date"), pursuant to the provisions of the Share Purchase Agreement, ("the purchase agreement"), the Company acquired 100 percent of the stock of Avalere Health, Inc. ("Avalere"). Avalere is a provider of data-driven advisory services and business intelligence solutions primarily to the pharmaceutical and life sciences industry, as well as within their extensive array of client relationships with payors, providers and research institutions. Certain portions of the stated purchase price of $140,000 are contingent upon the achievement of financial and operational objectives, and other portions are subject to continued employment provisions. The Company completed the acquisition of Avalere through the use of cash on hand and the issuance of 235,737 shares, subject to sale restrictions, of Class A common stock. The addition of Avalere, with its more than 200 pharmaceutical and life sciences clients, as well as an extensive array of client relationships with payors, providers and research institutions, is expected to expand Inovalon's capabilities and client base into the expansive and adjacent markets of the pharmaceutical and life sciences industry.

A summary of the composition of the stated purchase price and fair value of the stated purchase price is as follows:

3. BUSINESS COMBINATIONS (in thousands, except share amounts) (Continued)

Estimates of fair value included in the consolidated financial statements, in conformity with ASC No. 820, Fair Value Measurements and Disclosures, represent the Company's best estimates and valuations. In accordance with ASC No. 805, Business Combinations, the allocation of the consideration value is subject to adjustment until the Company has completed its analysis, but not to exceed one year after the date of acquisition, which was September 1, 2015, to provide the Company with the time to complete the valuation of its assets and liabilities. As of December 31, 2015, the Company has completed and finalized its analysis and allocation of the consideration value to assets acquired and liabilities assumed. In addition, as discussed in Note 2, the Company early adopted the provisions of ASU 2015-16 and recorded measurement period adjustments that were identified in the process of finalizing the aforementioned analysis and allocation.

The following table summarizes the final purchase price allocation to assets acquired and liabilities assumed, including identification of measurement period adjustments:

	Preliminary Recorded Value			Measurement Period Adjustments			Final Recorded Value

The amounts attributed to identified intangible assets are summarized in the table below:

Acquisition-related costs were expensed as incurred. For year ended December 31, 2015, the Company incurred acquisition-related costs of $1,483 recognized within "General and administrative" expenses in the accompanying consolidated statements of operations.

The following table presents revenue and loss before taxes of Avalere since the acquisition date, September 1, 2015, included in the consolidated statements of operations for the year ended December 31, 2015:

The following table presents pro forma information, based on estimates and assumptions that the Company believes to be reasonable, for the Company as if the acquisition of Avalere had occurred at the beginning of the earliest period presented:

The pro forma information provided in the table above is not necessarily indicative of the consolidated results of operations for future periods or the results that actually would have been realized had the acquisition been completed at the beginning of the periods presented.

During September 2014, the Company completed a holding company reorganization. As part of the reorganization, the Company implemented a multi-class stock structure. The Company has retrospectively presented the impact on net income per share (EPS) of this reorganization by calculating EPS based on the newly authorized, issued and outstanding shares of Class A and Class B

4. NET INCOME PER SHARE (in thousands, except per share amounts) (Continued)

common stock. Holders of all outstanding classes of common stock participate ratably in earnings on an identical per share basis as if all shares were a single class.

The Company has issued restricted share awards of Class A common stock (RSAs) under the 2015 Omnibus Incentive Plan. The Company considers issued and unvested RSAs to be participating securities as the holders of these RSAs have a non-forfeitable right to dividends in the event of the Company's declaration of a dividend on shares of Class A and Class B common stock. Subsequent to the issuance of the participating securities, the Company applied the two-class method required in calculating net income per share of Class A and Class B common stock.

Undistributed net income for a given period is apportioned to participating securities based on the weighted-average shares of each class of common stock outstanding during the applicable period as a percentage of the total weighted-average shares outstanding during the same period.

Under the two-class method, net income attributable to common stockholders is determined by allocating undistributed earnings, calculated as net income, less earnings attributable to participating securities. The net income per share attributable to common stockholders is allocated based on the contractual participation rights of the Class A common stock and Class B common stock as if the income for the period has been distributed. As the liquidation and dividend rights are identical for both classes of common stock, the net income attributable to common stockholders is allocated on a proportionate basis.

The Company has issued Class A common stock and Class B common stock. Holders of Class A common stock generally have the same rights, including rights to dividends, as holders of Class B common stock, except that holders of Class A common stock have one vote per share while holders of Class B common stock have ten votes per share. Each share of Class B common stock will convert into one share of Class A common stock immediately upon its sale or transfer. As such, basic and fully diluted earnings per share for Class A common stock and Class B common stock are the same.

Basic net income per share of common stock is computed by dividing the net income attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. All participating securities are excluded from the basic weighted-average shares of common stock outstanding. Unvested RSAs are excluded from the calculation of the weighted-average shares of common stock until vesting occurs, as the restricted shares are subject to forfeiture and cancellation until vested. For purposes of the diluted net income per share attributable to common stockholders calculation, unvested shares of common stock resulting from RSAs are considered to be potentially dilutive shares of common stock.

Diluted net income per share attributable to common stockholders is computed by dividing net income attributable to common stockholders by the weighted-average shares outstanding, including potentially dilutive shares of common stock assuming the dilutive effect of potential shares of common stock for the period determined using the treasury stock method. Potentially dilutive securities also include stock options, restricted stock units, and shares to be purchased under the employee stock purchase plan. Under the treasury stock method, dilutive securities are assumed to be exercised at the beginning of the periods and as if funds obtained thereby were used to purchase common stock at the average market price during the period. Securities are excluded from the computations of diluted net income per share if their effect would be anti-dilutive to earnings per share.

4. NET INCOME PER SHARE (in thousands, except per share amounts) (Continued)

The numerators and denominators of the basic and diluted EPS computations, reconciliations of the weighted average shares outstanding, and resulting basic and diluted earnings per share for our common stock are calculated as follows:

Net income per share attributable to common stockholders—diluted	$	0.45	$	0.49	$	0.24

The computation of diluted EPS does not include 645, and 1,234, and 4,905 equity awards for the years ended December 31, 2015, 2014, and 2013, respectively, because their inclusion would have an anti-dilutive effect on EPS.

The following table summarizes the estimated fair value of our short-term investments, designated as available-for-sale and classified by the contractual maturity date of the securities as of the dates shown:

The Company has certain available-for-sale securities in a gross unrealized loss position, all of which have been in such position for less than 12 months. The Company reviews its debt securities classified as short-term investments on a regular basis to evaluate whether or not any security has experienced an other-than-temporary decline in fair value. The Company considers factors such as the length of time and extent to which the market value has been less than the cost, the financial position and near-term prospects of the issuer and the Company's intent to sell, or whether it is more likely than not the Company will be required to sell the investment before recovery of the investment's amortized-cost basis. If the Company determines that an other-than-temporary decline exists, or if write downs related to credit losses are necessary, in one of these securities, the unrealized losses attributable to the respective investment would be reclassified to realized losses on short-term investments within the statement of operations. There were no impairments considered other-than-temporary as of December 31, 2015.

The following table shows the fair values and the gross unrealized losses of available-for-sale securities that have been in a gross unrealized loss position for less than 12 months, aggregated by investment category as of December 31, 2015:

The following table presents the fair value hierarchy for financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2015:

The Company determines the fair value of its security holdings based on pricing from its pricing vendors. The valuation techniques used to measure the fair value of financial instruments having Level 2 inputs were derived from non-binding consensus prices that are corroborated by observable market data or quoted market prices for similar instruments. Such market prices may be quoted prices in active markets for identical assets (Level 1 inputs) or pricing determined using inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs). The Company performs procedures to ensure that appropriate fair values are recorded such as comparing prices obtained from other sources.

On September 1, 2015, the Company recorded contingent consideration at it fair value in conjunction with the acquisition of Avalere. The Company determines fair value of its contingent consideration, using Level 3 inputs under the fair value hierarchy, consisting of information provided by observing certain operating metrics along with management's own assumptions. The Company adjusts

the estimated fair value of its contingent consideration quarterly. The change in value is reflected in our statements of operations as gain (loss) from contingent consideration valuation as a component of general and administrative expenses. During the year ended December 31, 2015 the fair value of the Company's contingent consideration decreased $100 as a result of finalizing the Company's analysis and allocation of the consideration value to assets acquired and liabilities assumed.

As of December 31, 2014, the Company measured its money market investment balances, included in cash and cash equivalents, at fair value based on quoted prices that are equivalent to cost (Level 1); the Company did not have any assets measured at fair value on a recurring basis using significant other observable inputs (Level 2), or significant unobservable inputs (Level 3), or any liabilities measured at fair value as prescribed by ASC 820-10.

The Company leases certain office equipment under capital lease agreements, with bargain purchase options at the end of the lease term. Leased office equipment included in property and equipment at December 31, 2015 and 2014 was $734 and $961, respectively.

Depreciation expense for the years ended December 31, 2015, 2014, and 2013 was $19,221, $15,512, and $11,918, respectively. Amortization of the capital leases included in depreciation expense was $118, $133, and $115, for the years ended December 31, 2015, 2014, and 2013, respectively. At December 31, 2015 and 2014, the Company had unamortized capitalized software costs, including costs classified as work in progress, of $38,165 and $28,417, respectively.

At December 31, 2015 and 2014, work in process consisted primarily of purchased software licenses, computer equipment, and capitalized software, which was not placed into service.

Goodwill is primarily derived from the Company's acquisitions of Avalere in 2015, Catalyst Information Technologies, Inc. in 2009, and Medical Reliance Group, Inc. in 2006. Refer to Note 3 for further information regarding the goodwill that arose from the Company's acquisition of Avalere during 2015.

The following table summarizes the activity related to the carrying value of our goodwill during the years ended December 31, 2015 and 2014:

8. GOODWILL AND INTANGIBLE ASSETS (in thousands, except years) (Continued)

Driven primarily by the accelerated arrival of advancing generations of technological software capabilities, management decided to discontinue the use of proprietary software technology, acquired in the Medical Reliance Group acquisition, with an initial expected useful life of ten years. The Company shortened the life of the intangible asset, and accelerated straight-line amortization over the period of time the Company transitioned to an advanced software application, which occurred during 2015. At December 31, 2015 and 2014, the net carrying value of this proprietary software technology was zero and $281, respectively.

Amortization expense for the years ended December 31, 2015, 2014, and 2013 was $3,412, $4,368, and $3,599, respectively.

Estimated future amortization expense of intangible assets, based upon the Company's intangible assets at December 31, 2015, is as follows:

On September 19, 2014, the Company entered into a Credit and Guaranty Agreement ("Credit Agreement"), with a group of lenders including Goldman Sachs Bank USA, as administrative agent, to provide credit facilities in the aggregate maximum principal amount of $400,000, consisting of a senior unsecured term loan facility in the original principal amount of $300,000 (the "Term Loan Facility"), and a senior unsecured revolving credit facility in the maximum principal amount of $100,000 (together with the Term Loan Facility, the "Credit Facilities").

The revolving credit facility became available to the Company on February 18, 2015, upon the consummation of its IPO.

The Company's borrowing rate under the Credit Facilities is dependent on whether the Company elects Eurodollar loans or base rate loans. Interest accrues on Eurodollar loans at a defined Eurodollar rate, defined as the London Interbank Offer Rate ("LIBOR") plus the applicable margin of 1.25%, as defined in the Credit Agreement. Interest is payable monthly in arrears.

The Credit Facility requires the Company to comply with specified financial covenants, including the maintenance of a $50,000 minimum cash and cash equivalents balance as of each calendar quarter end. The minimum cash and cash equivalents balance is not required to be held with any of the group of lenders and may be commingled with the Company's operating funds. The Credit Facility also contains various covenants, including affirmative covenants with respect to certain reporting requirements and maintaining certain business activities, and negative covenants that, among other things, may limit or impose restrictions on the Company's ability to incur liens, incur additional indebtedness, make investments, make acquisitions and undertake certain additional actions. As of, and during, the year ended December 31, 2015, the Company was in compliance with the financial covenants under the Credit Agreement.

Operating Leases—The Company leases office space under operating lease arrangements, some of which contain renewal options. Future non-cancellable lease payments as of December 31, 2015 are as follows:

Total expense under operating leases was $7,178, $7,438, and $6,572, during the years ended December 31, 2015, 2014, and 2013, respectively. Certain operating leases contain rent escalation clauses, which are recorded on a straight-line basis over the initial term of the lease, with the difference between the rent paid and the straight-line rent recorded as a deferred rent liability. Lease incentives received from landlords are recorded as deferred rent liabilities and are amortized on a straight-line

basis over the lease term as a reduction to rent expense. The deferred rent liability was $3,243 and $3,186 at December 31, 2015, and 2014, respectively.

Capital Leases—The total capital lease liability at December 31, 2015 and 2014 was $405 and $267, respectively, which approximates fair value due to the short duration of the obligations.

Letter of Credit—During 2014 the Company maintained a letter of credit with its primary commercial financial institution. As of December 31, 2015 and 2014, the outstanding letter of credit was $0 and $247, respectively. The letter of credit was in lieu of a security deposit for the Company's corporate office. During 2015 the letter of credit was eliminated.

Litigation—From time to time, the Company is involved in various litigation matters arising out of the normal course of business. The Company consults with legal counsel on those issues related to litigation and seeks input from other experts and advisors with respect to such matters. Estimating the probable losses or a range of probable losses resulting from litigation, government actions and other legal proceedings is inherently difficult and requires an extensive degree of judgment, particularly where the matters involve indeterminate claims for monetary damages, may involve discretionary amounts, present novel legal theories, are in the early stages of the proceedings, or are subject to appeal. Whether any losses, damages or remedies ultimately resulting from such matters could reasonably have a material effect on the Company's business, financial condition, results of operation, or cash flows will depend on a number of variables, including, for example, the timing and amount of such losses or damages (if any) and the structure and type of any such remedies. The Company's management does not presently expect any litigation matters to have a material adverse impact on the consolidated financial statements of the Company.

11. STOCK-BASED COMPENSATION (in thousands, except share and per share amounts, years, and percentages)

On December 31, 2006, the Company and its stockholders established the 2007 Long-Term Incentive Plan, or Plan, under which the Company's Board of Directors, at its discretion, could grant stock options to employees and certain directors of the Company. During 2009, the Plan was amended and currently authorizes the grant of stock options or other equity instruments for up to 10,275,000 shares of common stock. The stock options granted under the Plan generally expire at the earlier of a specified period after termination of service or the date specified by the Board of Directors at the date of grant, but not more than ten years from such grant date. Stock issued as a result of exercised stock options will be issued from the Company's authorized available stock. Effective June 5, 2012, the 2007 Long-Term Incentive Plan changed its name to the Inovalon, Inc. 2007 Long-Term Incentive Plan. Options granted under the Plan may be incentive stock options or non-qualified stock options under the applicable provisions of the Internal Revenue Code. The 2007 Long-Term Incentive Plan was terminated upon completion of the IPO. Awards granted under the 2007 Long-Term Incentive Plan will remain outstanding until the earlier of exercise, forfeiture, cancellation or expiration.

On February 18, 2015, the date of the completion of the Company's IPO, the Company's 2015 Omnibus Incentive Plan (the "2015 Plan") became effective. The 2015 Plan provides for the grant of incentive stock options, within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), to the Company's employees and any parent and subsidiary employees, and for

11. STOCK-BASED COMPENSATION (in thousands, except share and per share amounts, years, and percentages) (Continued)

the grant of non-qualified stock options, stock appreciation rights, restricted stock, RSAs, RSUs, dividend equivalent rights, cash-based awards (including annual cash incentives and long-term cash incentives), and any combination thereof to the Company's employees, directors, and consultants and to employees, directors, and consultants of certain affiliated entities. The Company reserved for issuance under the 2015 Plan shares of its Class A common stock equal to the sum of: (i) 7,335,430 shares of Class A common stock; and (ii) the number of shares of its Class A common stock underlying awards granted under the Company's 2007 Long-Term Incentive Plan, which was terminated upon completion of the IPO, that are forfeited, canceled, or expire (whether voluntarily or involuntarily).

The Company selected the Black-Scholes option-pricing model as the most appropriate model for determining the estimated fair value for stock-based awards. The Black-Scholes option-pricing model requires the use of estimates, including the fair market value of the Company's common stock prior to the Company's IPO, expected stock price volatility, expected term, estimated forfeitures and the risk-free interest rate. The fair value of stock option awards is amortized on a straight-line basis over the requisite service period of the awards, which is generally the vesting period. The amount of stock-based compensation expense recognized is based on the estimated portion of the awards that are expected to vest. Actual and anticipated forfeiture rates were applied in the expense calculation.

Prior to the Company's IPO, determining the fair value of the Company's common stock required complex and subjective judgment and estimates. There is inherent uncertainty in making these judgments and estimates. Since the Company's share price was not publicly quoted and lacked an active trading market prior to the Company's IPO in February 2015, the Company's Compensation Committee was required to estimate the fair value of the common stock at each meeting at which options were granted based on factors including, but not limited to, contemporaneous valuations of the Company's common stock performed by an unrelated third-party specialist, the lack of marketability of the Company's common stock, developments in the business, share repurchase arrangements, the status of the Company's development and sales efforts, revenue growth, valuations of comparable companies, and additional objective and subjective factors relating to the Company's business.

The Company did not grant any options during 2015. The fair value of each option grant is estimated on the date of grant applying the Black-Scholes option pricing model using the following assumptions:

Expected volatility was calculated as of each grant date based on reported data for several unrelated public companies within the Company's industry that are considered to be comparable to the Company and for which historical information was available. The average expected term was determined under the simplified calculation as provided by the Securities and Exchange Commission's

11. STOCK-BASED COMPENSATION (in thousands, except share and per share amounts, years, and percentages) (Continued)

Staff Accounting Bulletin No. 107, Share-Based Payment, which is the mid-point between the vesting date and the end of the contractual term. The dividend yield assumption of zero is based upon the fact that the Company does not have a formal dividend payment policy, the Company does not intend to pay cash dividends on its common stock in the future, and, to the extent the Company pays dividends in the future, there is no assurance that any such dividends will be comparable to those previously declared. Any declarations of dividends and the establishment of future record and payment dates are subject to the final determination of the Company's Board of Directors. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve rates with the remaining term commensurate with the expected life assumed at the date of grant. Forfeitures are estimated based on historical experience and adjustments are made annually to reflect actual forfeiture experience.

The total grant-date fair value of stock options granted during the years ended December 31, 2015, 2014, and 2013 was $0, $14,922, and $3,661, respectively. The weighted average grant-date fair value per share of stock options granted during the years ended December 31, 2015, 2014, and 2013, was $0, $9.07, and $2.94, respectively.

As of December 31, 2015, there is $4.8 of total unrecognized compensation expense related to unvested stock options, and this expense is expected to be recognized over a weighted-average period of 3.2 years.

The aggregate intrinsic value in the table above represents the total intrinsic value (the difference between the fair value of the Company's common stock and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option

holders exercised their options. This amount is subject to change based on changes to the fair market value of the Company's common stock.

On November 13, 2014, the Company granted 488,780 RSUs pursuant to the Company's 2007 Long-Term Incentive Plan. The RSUs had a grant date fair value of $9,722. The Company used the fair market value of the underlying common stock on the date of grant to determine the fair value of RSUs, which was $19.89 per RSU. The RSUs vest upon the satisfaction of both a service condition and a liquidity condition. The service condition for these awards is satisfied over five years. The liquidity condition is satisfied upon the occurrence of a qualifying event, defined as a change of control transaction or six months following the completion of the Company's IPO. As of December 31, 2014, no share-based compensation expense had been recognized for these RSUs because the qualifying events (described above) had not occurred. This six-month period following the IPO is not a substantive service condition and, accordingly, in 2015, the year in which the Company consummated its IPO, the Company recognized a cumulative share-based compensation expense for the portion of the RSUs that had met the service condition as of that date, following the straight-line method, net of estimated forfeitures. All remaining unrecognized share-based compensation expense related to these RSUs will be recorded over the remaining requisite service period using the straight-line method, based on awards ultimately expected to vest. The Company estimates future forfeitures at the date of grant and revises the estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

On March 5, 2015, the Company granted 76,273 RSUs pursuant to the 2015 Plan. The awards granted vest ratably over five years on each anniversary of the award grant date, and upon vesting, the Company will deliver to the holder shares of the Company's Class A common stock under the 2015 Plan. Pursuant to the terms of the awards, any unvested shares terminate upon the RSU holders' separation from the Company. The grant date fair value of the RSUs was $2,337, in aggregate, or $30.64 per RSU. The Company will recognize share-based compensation expense following the straight-line method, net of estimated forfeitures, over the requisite service period. The Company estimates future forfeitures at the date of grant and revises the estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

11. STOCK-BASED COMPENSATION (in thousands, except share and per share amounts, years, and percentages) (Continued)

As of December 31, 2015, there was a total of $7,188 in unrecognized compensation cost, net of estimated forfeitures, related to unvested RSUs, which are expected to be recognized over a weighted-average period of approximately 3.93 years.

On May 28, 2015, the Company granted 71,946 RSAs pursuant to the 2015 Plan. RSAs granted to directors fully vest upon the one year anniversary of the award grant date, and RSAs granted to employees vest ratably over five years on each anniversary of the award grant date. Upon vesting, the Company will deliver shares of the Company's Class A common stock to the holders. Pursuant to the terms of the awards, any unvested shares terminate upon the RSA holders' separation from the Company. The grant date fair value of the RSAs was $2,000, in aggregate, or $27.80 per RSA. The Company recognizes share-based compensation expense for the RSAs following the straight-line method, net of estimated forfeitures, over the requisite service period. The Company estimates future forfeitures at the date of grant and revises the estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

On November 12, 2015, the company granted 524,105 RSAs pursuant to the 2015 Plan. The RSAs were granted to employees and vest ratably over five years on each anniversary of the award grant date. Upon vesting, the Company will deliver shares of the Company's Class A common stock to the holders. Pursuant to the terms of the awards, any unvested shares terminate upon the RSA holders' separation from the Company. The grant date fair value of the RSAs was $9,198, in aggregate, or $17.55 per RSA. The Company recognizes share-based compensation expense for the RSAs following the straight-line method, net of estimated forfeitures, over the requisite service period. The Company estimates future forfeitures at the date of grant and revises the estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

As of December 31, 2015, there was a total of $7,401 million in unrecognized compensation cost, net of estimated forfeitures, related to unvested RSAs, which are expected to be recognized over a weighted-average period of approximately 4.8 years.

11. STOCK-BASED COMPENSATION (in thousands, except share and per share amounts, years, and percentages) (Continued)

On February 18, 2015, the date of the completion of the Company's IPO, the 2015 Employee Stock Purchase Plan ("2015 ESPP") became effective. The 2015 ESPP provides for (i) six-month purchase periods (commencing each March 1 and September 1) and (ii) that the purchase price for shares of Class A common stock purchased under the 2015 ESPP will be 85% of the fair market value of the Company's Class A common stock on the last day of the applicable offering period. Eligible employees are able to select a rate of payroll deduction between 1% and 15% of their base cash compensation subject to a maximum payroll deduction per offering period of $7,500. The 2015 ESPP is intended to qualify as an employee stock purchase plan under Section 423 of the Code. The Company reserved 1,833,857 shares of Class A common stock for issuance under the 2015 ESPP. During the year ended December 31, 2015, the Company purchased and issued 30,689 shares of common stock to 2015 ESPP participants at a discounted price of $18.61 per share and recorded stock-based compensation related to the 2015 ESPP of $156.

On June 1, 2007, the Company adopted a 401(k) Profit Sharing Plan and Trust, or 401(k) Plan. The 401(k) Plan was amended on February 1, 2010. The amended 401(k) Plan allows employees to become eligible to participate upon the completion of 30 days of service. The Company matches employee contributions up to 4.0% of their compensation and the employer contributions vest immediately.

The Company has a separate defined contribution retirement plan for employees of Avalere. Under this 401(k) retirement plan, employees can make voluntary contributions to the retirement program in the form of salary reductions. Additionally, the Company matched 100% of employee deferrals up to 5% of qualifying compensation for all eligible participants. There is a one year waiting period for eligibility from date of hire. Participants are fully vested in both the employee deferral and employer contributions upon meeting eligibility requirements.

During the years ended December 31, 2015, 2014, and 2013, total expense recorded for the Company's matching 401(k) contributions were $4,227, $2,820, and $2,846, respectively.

In February 2013, to provide liquidity to certain existing stockholders who desired liquidity and to reduce the number of stockholders and outstanding shares of common stock, the Company initiated a share repurchase and liquidity initiative for and among existing stockholders. During 2013, the Company repurchased 10,703,360 shares of common stock for aggregate consideration of $72,114 and sold 7,216,610 shares of common stock for $52,114, resulting in a net repurchase of 3,486,750 treasury stock shares at an aggregate net cost of $20,000. Upon repurchase, the treasury stock shares were immediately retired. In connection with the retirement, of the $20,000 value assigned to the treasury stock shares, $2,403 was allocated to additional paid-in capital and $17,597 was allocated to retained earnings. The amount allocated to additional paid- in capital was determined based on the paid-in capital per share generated from the historical issuances of these treasury stock shares.

13. STOCKHOLDERS' EQUITY (DEFICIT) (in thousands, except share amounts) (Continued)

During June 2014, the Company repurchased 1,462,320 shares at a cost of $9,066. Upon repurchase, the shares were immediately retired. In connection with the retirement, of the $9,066 value assigned to the repurchased shares, $1,011 was allocated to additional paid-in capital and $8,055 was allocated to retained earnings. The amount allocated to additional paid-in capital was determined based on the paid-in capital per share generated from the historical issuances of these shares.

On September 16, 2014, in connection with the holding company reorganization, the Company's common stock was reclassified to implement a multi-class capital structure providing for common stock, Class A common stock and Class B common stock. Each share of common stock held by the then-existing stockholders of Inovalon, Inc. at the time of the holding company reorganization was reclassified as Class B common stock of the Company.

On September 19, 2014, the Company authorized the pro-rata redemption of approximately 8.33% of the Company's outstanding Class B common stock from the then-existing holders. During September 2014, the Company completed the pro-rata redemption and repurchased 11,109,285 shares of Class B common stock for $300,017, which automatically converted from Class B common stock to Class A common stock. This redemption occurred at a price per share of $27.01, which was in excess of the estimated fair value of our common stock of $19.89 per share as of September 30, 2014 calculated for the purpose of determining our stock-based compensation expense. The estimated fair value of our common stock on a per share basis, as of September 30, 2014, was based upon a contemporaneous valuation of the Company's common stock performed in conjunction with an unrelated third-party specialist and the calculation of the estimated fair value of the common stock includes certain assumptions and discounts that are required to be applied to the valuations of privately held companies. The Company did not contribute nor receive any stated or unstated rights, privileges, or other consideration as part of the redemption, therefore, at December 31, 2014, these repurchased 11,109,285 Class A shares of common stock were held and accounted for as treasury shares.

On February 18, 2015, the Company completed its initial public offering of 22,222,222 shares of Class A common stock and, upon the underwriters' exercise of their option to purchase additional shares, issued an additional 3,142,581 shares of Class A common stock for a total of 25,364,803 shares issued (the "IPO"). All of the shares issued in the IPO were primary shares offered by the Company as none of the Company's stockholders sold any shares in the IPO. The offering price of the shares sold in the IPO was $27.00 per share, resulting in net proceeds to the Company, after the underwriters' discounts and commissions and other expenses, payable by the Company, of approximately $639.1 million.

The provision for income taxes reconciles to the amount computed by applying the federal statutory rate (35.0%) to income before income taxes as follows:

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company's deferred tax assets and liabilities were as follows:

Total deferred tax liabilities		46,061		19,901

Net deferred tax liabilities	$	36,966	$	14,672

The deferred tax liability has been classified in the accompanying consolidated balance sheets as follows:

Uncertain Tax Positions—During the years ended December 31, 2015, 2014, and 2013, changes in the liability for gross unrecognized tax benefits, including interest, totaled $0, $0, and $48, respectively. At December 31, 2015 and 2014, the Company did not measure a liability for unrecognized tax benefits.

Net Operating Losses carryforwards(NOLs)—At December 31, 2015, we had federal net operating loss ("NOL") carryforwards of approximately $5.0 million. These NOL carryforwards will expire in 2036.

While the Company believes it has adequately provided for all tax positions, amounts asserted by taxing authorities could differ from the Company's accrued position. Accordingly, additional provisions

on federal, state and foreign tax-related matters could be recorded in the future as revised estimates are made or the underlying matters are settled or otherwise resolved.

The Company is subject to taxation by the United States of America, various United States of America jurisdictions, and Puerto Rico. The number of years with open tax audits varies depending on the tax jurisdiction.
