PART I

Item 1. Business

Overview

Teladoc, Inc. is a Delaware corporation that was originally formed in Texas on June 13, 2002 and reincorporated in Delaware on October 16, 2008.

We are the largest and most trusted virtual healthcare provider in the world. Recognized by MIT Technology Review as one of the “50 Smartest Companies”, we are forging a new healthcare experience with better convenience, outcomes and value. We provide virtual access to high quality care and expertise, with a portfolio of services and solutions covering 450 medical subspecialties from non-urgent, episodic needs like flu and upper respiratory infections, to chronic, complicated medical conditions like cancer and congestive heart failure. By marrying the latest in data and analytics with an award-winning user experience and a highly flexible technology platform, we have delivered millions of medical visits to patients around the globe.

On July 14, 2017, we completed the acquisition of Best Doctors Holdings, Inc. (“Best Doctors”), an expert medical consultation company. Best Doctors provides technology innovations and services to help employers, health plans and provider organizations to improve health outcomes for the most complex, critical and costly medical issues.

Over 23 million unique Members now benefit from access to Teladoc 24 hours a day, seven days a week, 365 days a year. We completed approximately 1,463,000 telehealth visits in 2017 and approximately 952,000 telehealth visits in 2016. Paid membership increased by approximately 5.7 million members from December 31, 2016 through December 31, 2017 including the impact from Best Doctors.

Our portfolio of solutions transform the access, cost and quality dynamics of healthcare delivery for all of our market participants. Our Members rely on Teladoc for a single point of virtual access to resolution to a broad array of healthcare needs, ranging from the flu, to behavioral health to cancer, in an experience designed to meet the expectations of today’s consumers. Employers, health plans, provider organizations, insurance and financial services companies and consumers (our “Clients”) purchase our solutions to reduce their healthcare spending, or to provide a market differentiating service as a complement to their core set of consumer service offerings, while at the same time offering convenient, affordable, high-quality healthcare to their employees or beneficiaries.  

We believe the value proposition of our solutions is evidenced by our overall Member satisfaction rate of 90% over the last nine years. We further believe any consumer, employer, health plan or provider, insurance and financial service companies interested in a better approach to healthcare is a potential Teladoc Member, Client or Provider.

The U.S. healthcare system is experiencing a growing crisis of access, cost and quality of care due to inefficiencies in today’s healthcare system and barriers between participants. According to the National Association of Community Health Centers, or the NACHC, approximately 62 million individuals in the United States currently have no or inadequate access to primary care as a result of physician shortages. Absent convenient access to a primary care physician, individuals will most likely either not seek care at all or visit emergency rooms or urgent care clinics, the most expensive and often inefficient settings for their primary care needs.

These market dynamics impact not only the consumers seeking care, but also the health plans, employers and health systems that ultimately bear all or a portion of these costs. According to the Centers for Disease Control and Prevention, or the CDC, there are approximately 1.25 billion ambulatory care visits in the United States per year, including those at primary care offices, hospital emergency rooms, outpatient clinics and other settings. We estimate that approximately 417 million, or 33%, of these visits could be treated through telehealth. We believe that the total addressable market for telehealth in the United States consists of the ambulatory care telehealth opportunity, a subset of visits currently delivered in urgent and retail care settings and care foregone by those currently not accessing the healthcare delivery system.

Additionally, according to the US Department of Health and Human Services Agency for Healthcare Research and Quality, or the AHRQ, there are approximately 168 million behavioral health visits completed in provider offices in the United States per year. We estimate that approximately 131 million, or 78%, of these visits could be treated through telehealth.

Innovators in other industries have solved access, cost and quality inefficiencies through the implementation of technology platforms and business models that deliver products and services on‑demand and create new economies by connecting and empowering both consumers and businesses. We have taken the same approach to solving the pervasive access, cost and quality challenges facing the current healthcare system. We believe we have created portfolio of solutions uniquely positioned to bridge the supply and demand gap between physicians and consumers by fundamentally changing the way market participants access and deliver healthcare—eliminating traditional barriers and inefficiencies between participants and empowering them to engage in a healthcare marketplace anytime, anywhere.

Our solution offers our Clients proven substantial savings opportunities and an attractive return on investment. A study we commissioned with Veracity Analytics, an independent healthcare data analytics company, to perform an independent study of several Clients representing nearly 2 million of our Members as of the end of 2016, found that these Clients saved $472 on average per visit when its Members received care through Teladoc instead of receiving care in other settings for the same diagnosis. Combined with average employee productivity savings of $46, estimated from data provided by the Bureau of Labor Statistics, we saved our Clients approximately $493 million in healthcare delivery costs in 2016.

We currently serve over 10,000 employers, health plans, health systems and other entities. These Clients collectively purchase access to our solution for more than 23.2 million Members. We believe our business to business to consumer, or B2B2C, distribution strategy is one of the most efficient methods to reach consumers and deliver telehealth to our Members. We have over 35 health plans as Clients, including some of the largest in the United States such as Aetna, Blue Shield of California, Blue Cross and Blue Shield of Alabama, Premera Blue Shield and UnitedAd. Health plans serve as Clients as well as distribution channels to self‑insured employer Clients that contract with us through a health plan relationship. Our employer Clients include over 40% of the Fortune 1000 companies. The remainder of our Clients are from channel partners such as brokers, resellers and consultants who sell into a range of small, medium and large enterprises.

We generate revenue from our Clients on a contractually recurring, per-Member-per-month, subscription access fee basis, which provides us with significant revenue visibility. In addition, we generate additional revenue on a per-telehealth general medical visit basis, through a visit fee. Certain of our Client contracts generate revenue for expert second opinions on a per case basis. Subscription access fees are paid by our Clients on behalf of their employees, dependents, policy holders, card holders, beneficiaries or themselves, while general medical and other specialty visit fees are paid by either Clients or Members. We generated revenue of $233.3 million (including $47.0 million from Best Doctors), $123.2 million and $77.4 million in revenue in 2017, 2016 and 2015, respectively, representing 89% and 59% year‑over‑year growth from 2016 to 2017 and from 2015 to 2016, respectively. For the year ended December 31, 2017, 85% and 15% of our revenue were derived from subscription access fees and visit fees, respectively. For the years ended December 31, 2016 and 2015, 82% and 18% of our revenue were derived from subscription access fees and visit fees, respectively. We believe these results are representative of the value proposition we can provide the broader U.S. healthcare system.

Our Opportunity

Barriers and inefficiencies in the current U.S. healthcare system present market participants with three major challenges: (i) consumers lack sufficient access to high‑quality, cost‑effective healthcare at appropriate sites of care, while bearing an increasing share of costs; (ii) employers and health plans lack an effective solution that reduce costs while enhancing healthcare access for beneficiaries; and (iii) providers lack flexibility to increase productivity by delivering care on their own terms. Market participants are therefore increasingly unable to effectively and efficiently receive, deliver or administer healthcare. At the same time, the emergence of technology platforms solving massive structural challenges in other industries has highlighted the need for a similar solution in healthcare. We believe there is a significant opportunity to solve these challenges through trusted solutions, such as ours, that match consumer demand

and physician supply at the time of need, provide consumers access to medical opinions from leading global experts, and offer health plans and employers attractive, cost-effective healthcare alternatives for their beneficiaries.

Growing Healthcare Access Crisis for Consumers

Consumers in the United States are increasingly challenged to obtain access to affordable healthcare at appropriate sites of care when care is most needed.  According to a 2017 Merritt Hawkins study, the average lead time to see a primary care physician across various metro areas was 29 days. We also believe issues around access are projected to get worse. A 2017 study from IHS Markit prepared for the Association of American Medical Colleges found that physician demand continues to grow faster than supply, resulting in a projected total physician shortfall of up to 104,900 physicians by 2030, including a shortage of approximately 43,100 primary care physicians. We believe this projection is supported by the 2016 Survey of America’s Physicians, in which 80.6% of physicians describe themselves as either over-extended or at full capacity. Expected population growth and aging, and the projected gap between supply and demand for access to healthcare services, will place additional pressure on an already overburdened healthcare system that lacks physician capacity and diagnoses-appropriate access points.

This access crisis has resulted in U.S. consumers either seeking care at inappropriate, more costly settings such as hospital emergency rooms, or foregoing needed care entirely. A 2015 survey from the American College of Emergency Physicians found that almost 50% of physicians polled stated that demands for care coordination including emergency department visits are increasing due to increased difficulty in finding or arranging timely follow-up with primary care physicians and/or specialists. In the same survey, 70% of physicians polled also noted that they believe their emergency department is not adequately prepared for potentially substantial increases in patient volume.

In addition to challenges finding care, consumers also face challenges accessing the highest-quality care. Owing to reasons ranging from complexity of symptoms, the unusual nature of disease, or physician expertise, medical diagnoses are often incorrect. A 2017 study by the Mayo Clinic published in Journal of Evaluation in Clinical Practice showed that among a sample of cases that had been referred for second opinions, in 12% of cases the final diagnoses matched the primary diagnoses, in 66% of cases the final diagnoses refined the primary diagnoses, and in 21% of cases the final diagnoses were materially different than the primary diagnoses. Reducing unnecessary treatment related to misdiagnosis has a significant impact on the quality and cost of care a patient receives.

Healthcare Cost Burden and Lack of Viable Options for Health Plans and Employers

The U.S. healthcare system is burdened by significant waste and extreme variations in access, cost and quality of care. A study published in The Journal of the American Medical Association estimates that approximately $734 billion, or 27%, of all healthcare spending in 2011 was wasted due to factors such as the provision of unnecessary services, inefficient delivery of care and inflated prices. When consumers are forced to seek care at inappropriate and more costly sites of care, those cost inefficiencies impact not only the consumer, but also the health plans and employers that ultimately bear all or a portion of these costs.

The costs and associated burdens on health plans, employers and consumers are only expected to increase. Centers for Medicare and Medicaid Services, or CMS, estimates U.S. national health expenditures reached $3.3 trillion, or approximately 17.9% of the U.S. GDP in 2016, and will reach approximately 19.9% of GDP by 2025. A survey from Milliman in 2017 noted that healthcare costs for an average American family of four exceeded $26,900 in 2017,  a 4.3% increase over 2016. A 2017 survey by the National Business Group on Health indicated that employers bear on average 70% of their employees’ healthcare costs and CMS forecasted U.S. employers spent approximately $660 billion on healthcare in 2015. Despite the significant amount of dollars spent, U.S. healthcare outcomes remain inferior relative to those of many other countries.

The unsustainable levels of spending on healthcare and extreme inefficiencies in the system have driven an increased focus by employers and health plans to control healthcare expenditures. Governments, private insurance companies and self-insured employers, are implementing meaningful cost containment measures, including shifting financial responsibility to patients through higher co-pays and deductibles and delivering healthcare through alternative, more cost-effective methods. According to a 2017 survey by America’s Health Insurance Plans (AHIP), as of January

2016, over 20 million Americans were enrolled in HSA-Qualified High-Deductible Health Plans, a 76% increase since 2011. The increasing shift of financial responsibility to patients coupled with increased pricing transparency has, in turn, heightened beneficiary focus on healthcare alternatives. As consumers take responsibility for a larger share of their healthcare costs and spend more on healthcare services, they are also demanding higher quality care, greater control in how and where they receive care, increased convenience and more service for every dollar spent.

Challenging Environment for Physicians is Constraining Supply

In response to increasing pressures, physicians are reducing access to healthcare in multiple ways. The 2016 Survey of America’s Physicians indicated that 48% of physicians plan to take steps to limit access to their practices, including cutting back on the number of patients seen, working part‑time, closing their practices to new members, seeking non‑clinical jobs or retiring. Notably, 47% of surveyed physicians indicated they plan to accelerate retirement given changes in the healthcare environment. A study by Physicians for a National Health Program showed medical billing paperwork and insurance‑related red tape cost the United States economy approximately $471 billion in 2012, 80% of which was wasted due to inefficiency. These constraints have driven physicians to seek more control over the way they deliver care to new and existing patients, increase their income and reduce the amount of time they spend on administration.

Physicians have responded to these challenges by shifting payment models and patient mix. Medscape’s 2017 Physician Compensation Report showed a 100% increase from 2012 to 2017 in the percent of physicians transitioning to cash-only models, no longer accepting insurance. A 2017 Merritt Hawkins study found that 47.0% of physicians in the United States’ 15 largest cities are not accepting new Medicaid patients. We believe there is a significant opportunity for a single source solution that addresses these physician needs.

Opportunity to Remove Barriers Through an Innovative Platform that Benefits All Participants

We believe we have a significant opportunity to solve access, cost and quality of care challenges through a platform that matches consumer demand and physician availability in real-time and asynchronously, and in various modalities such as video, web, mobile and telephone, while offering health plans and employers an attractive, cost-effective alternative for their beneficiaries through our platform. As consumerism in healthcare increases and consumers and providers become accustomed to on-demand services in other industries, they are similarly demanding technology-powered solutions for their healthcare needs. The emergence and subsequent rapid adoption of technologies such as big data and analytics, cloud-based solutions, online video and mobile applications represents an enormous opportunity for healthcare innovation. We believe the confluence of consumer empowerment, emergence of broad technology solutions and focus by all constituents on providing high-quality, cost-effective healthcare creates a unique opportunity for a disruptive platform that transforms the way consumers access, providers deliver and employers and health plans administer high-quality, cost-efficient healthcare.

Our Competitive Strengths

We believe the following are our key competitive strengths.

Leading and Only Comprehensive Virtual Care Delivery Solution

We service the full spectrum of healthcare market segments via our integrated technology platform, high quality Provider network, sophisticated consumer engagement strategies and entrenched distribution channels. We have a portfolio of strong brands, established strong relationships with Clients and are the global market leader in virtual healthcare delivery. Our history of innovation and long standing operations provide us with a significant first mover advantage, including what we believe are the following telehealth industry firsts and only:

The following graphic outlines the simple, convenient and intuitive Teladoc Member experience supported by our integrated, scalable and responsive solution:

Innovative Technology Platform

Our integrated solution positions us at the center of the patient, provider and payor relationship and as a key participant in the rapidly emerging, technology powered healthcare industry. We continually incorporate new product features into our platform to meet the evolving needs of the highly complex healthcare industry. We believe our technology platform contains several differentiating features, including the following:

 Highly Scalable Platform

Our platform is highly scalable and can currently provide the same level of Member support and response time for upwards of 50,000 visits per day versus our current rate of over 7,000 visits per day on average. Similarly, our platform is currently equipped to serve over 100 million Members. Further, our platform has been built to accommodate the seamless and quick introduction of new services and products, such as behavioral health, dermatology, expert second opinions, laboratory testing and other services that are currently in the development stages. We have the ability to respond quickly to evolving market needs with innovative solutions, such as mobile applications, biometric devices, mobile geofencing and at‑home testing, to enhance our solution and support our leadership position. We believe our highly scalable platform provides us with significant growth opportunities within our existing membership and client bases and allows us to grow with low capital expenditure requirements.

 Clinical Capabilities Tailored to Telehealth

We believe that by directly recruiting, credentialing, training and contracting with our Providers we have built our clinical capabilities in a manner that supports the operational complexity of and commitment to clinical quality required in telehealth. Our physician Providers are board‑certified with an average of 20 years of experience and are credentialed through an NCQA‑certified process. The NCQA’s accreditation process involves a comprehensive on‑site and off‑site review by a team of physicians and managed care experts that evaluates more than 60 quality‑related healthcare standards, including quality management and improvement and utilization management. The results of the evaluation are reviewed by the NCQA’s National Review Oversight Committee prior to their assigning an accreditation level. The NCQA’s requirements are developed with the input and support of health plans, providers, purchasers, unions and consumer groups. The NCQA’s accreditation process is not telehealth specific; rather, since its formation in 1990, the NCQA established, and consistently updates, its quality standards and performance measures for a broad range of healthcare entities by building consensus around important health care quality issues. In determining its quality standards and performance measures, the NCQA works with large employers, policymakers, doctors, patients and health plans to determine areas of focus and how to promote improvement within them. Health plans in every state, the District of Columbia and Puerto Rico are NCQA accredited. According to the NCQA, these certified plans cover 109 million Americans, or 70.5% of all Americans enrolled in health plans.

Our clinical capabilities are designed specifically for telehealth. For example, our Members have the option to share a record of every visit and their EMR with their existing primary care physicians. In circumstances where a Member reports that they do not have a primary care physician, the Teladoc Provider educates the Member on the importance of establishing this relationship. Prior to every visit, the Provider reviews the Member’s proprietary EMR and certifies to this review by completing a multi‑step checklist. During and following the visit, the Provider may reference our over 100 proprietary Evidence Based clinical guidelines and other telehealth‑specific content. In addition, Members and Providers remain connected following visits. Members receive personalized notes, patient education materials and are able to ask questions of our clinical team via the Teladoc Message Center. Approximately 10% of all physician visits are reviewed by our clinical quality assurance staff to ensure adherence to appropriate treatment and prescription patterns. We believe our track record of zero medical malpractice claims is a testament to our Providers’ clinical quality.

 Well‑Established Distribution Channels and Strategic Alliances

We have developed sales channels and strategic alliances which we believe provide an opportunity to sell our solution through trusted partners. Our solution is sold through a highly efficient and effective B2B2C distribution network wherein we reach consumers through our Clients and channel partners rather than marketing our solution directly to potential Members. We sell through a direct sales force to our Clients who in turn buy our solution on behalf of their beneficiaries. In addition, a range of third‑parties including brokers, agents, benefits consultants and resellers, whom we refer to as channel partners, sell our solution to various end markets. Notably, many of our health plan Clients also act as channel partners because they resell our solution to their administrative service only or ASO accounts and other customers, we also market our behavioral services directly to consumers through digital advertising campaigns. We believe the breadth of our distribution strategy allows us to directly reach consumers and also employers of nearly every size and in nearly every market, which are capable of purchasing our solution for a large number of beneficiaries, rather than attempting to sell our solution one consumer at a time.

Our Growth Strategies

The following are our key growth strategies.

   Expand Our Comprehensive Virtual Care Delivery Platform

Teladoc is creating a new paradigm for how consumers access healthcare. We are delivering a single solution to address the complete spectrum of conditions from non-critical, episodic care to chronic, complicated cases. Our mission is to become the central and trusted source for our Clients and Members to address the broadest array of healthcare needs, on their terms, anytime, anywhere. We refer to Teladoc’s integrated offering as our comprehensive Virtual Care Delivery Platform. Our Virtual Care Delivery Platform matches the expectations of today’s digital consumer with a new kind of healthcare experience, leveraging expansive digital clinical services, deep integration with the broader healthcare ecosystem, powerful data & analytics, device & wearables integration and ubiquitous entry points, all of them wrapped in our Surround Sound marketing to drive behavior change and engagement. Our suite of clinical services ranges from high volume, lower acuity offerings such as general medical, dermatology, behavioral health, tobacco cessation, and sexual health to lower volume, higher acuity offerings for Expert Second Opinions, Treatment Decision Support, Critical Care support, Specialty Pharmacy cost containment, and Oncology Insights with IBM Watson. 

We believe that our Virtual Care Delivery Platform addresses significant unmet needs. According to the 2012 white paper from the U.S. Department of Health and Human Services, approximately 46 million adults in the U.S. suffer from mental illness with more than 11 million adults reporting an unmet need for mental healthcare. Compounding this unmet need, the shortage of psychiatrists and behavioral health resources has become acute nationwide. According to a 2014 Merritt Hawkins report, psychiatrists are essentially aging out of the workforce, with over 70% of psychiatrists 50 years of age or older. The Teladoc provider network underpinning the Virtual Care Delivery Platform addresses the challenges of the current healthcare environment by offering our Clients & Members 24/7/265, on-demand access to

over 3,000 board-certified physicians and behavioral health professionals who treat a wide range of conditions and cases. With the addition of the Best Doctors global network, consisting of 50,000+ medical experts in more than 450 medical specialties, we are able to offer solutions to our Members for a range of critical, life-threatening cases such as cancer, musculoskeletal conditions, inflammatory disorders, heart conditions, chronic pain, and many other chronic, complex, and critical medical issues. Finally, we also offer direct-to-Member access to behavioral health professionals who treat conditions such as anxiety and depression.  By bringing these provider networks together under our Virtual Care Delivery Platform, we believe we have created an unrivaled offering that will enable the continued expansion of our product portfolio and solve the biggest challenges of our Clients and Members.

   Increase Engagement with Our Members by Driving Expanded Access & Enhanced Touch Points

We believe there is significant opportunity within our existing membership base to increase engagement by continually driving awareness of and loyalty to our solution. We believe our Virtual Care Delivery Platform can become the single source for on-demand, virtual care for our Members. We will continually refine and enhance our user experience, which is a critical driver of new and repeat engagement and we will continue validating our Member satisfaction with surveys and other proactive tools. We are also building robust data repositories to strengthen our predictive models and multi-channel marketing strategies to provide a more complete picture of our Members, enhancing our ability to lead targeted and purposeful campaigns. We will continue to invest heavily in marketing technologies that allow us to increase Member touch-points. In addition, we will continue to actively engage Clients in benefit design, worksite marketing and executive sponsorship strategies to drive awareness about our solution.

Our mobile app is foundational for Teladoc as we have redefined virtual care delivery and are providing our Members with a better way to navigate their individual care. In 2017, we launched an integrated mobile experience for our joint Teladoc and Best Doctors clients. Our Members now benefit from a single, patient-centered point of access to our Virtual Care Delivery Platform. Further, Consumers are increasingly using mobile devices to take control of their healthcare journey, with nearly 74% of Teladoc visits being requested through mobile. Our new integrated app experience enables our Members to meet their care needs, whenever and wherever they are, removing the complexities of accessing care. As we expand the range of products and services available to our Members, we are investing in a seamless, relevant, and personalized mobile experience that provides smart guidance for our Members. Members will only need to express their healthcare need through a user-friendly, AI-supported, guided interface, and they will be presented with the optimal product or pathway to meet that need.

 Expand Our Membership with New and Existing Clients

We believe that we offer a highly differentiated suite of solutions for a broad range of market segments, spanning the spectrum of traditional healthcare system participants such as employers, health plans and health systems as well as global financial services businesses and other organizations that have extended their investment in our industry. We intend to increase our membership by adding additional Members from both existing Clients, which we refer to as whitespace, and from new Clients. We plan to execute this strategy by further penetrating existing relationships and by pursuing new relationships through our distribution channels and an expanded sales team. Within existing accounts, we believe our current membership represents only a fraction of the potential Members available to us. Our existing health plan Clients and self‑insured Clients associated with these health plans currently purchase our solution for only a small percentage of their beneficiaries in the aggregate, and we estimate this provides us the opportunity to grow our membership base by more than 50 million individuals by expanding our penetration within our existing Clients alone. Similarly, we have 291 Fortune 1000 Clients, representing a significant opportunity for new Client growth with large employers. A key focus for us in 2018 will be to cross-sell and upsell these Clients our full suite of services. We are investing heavily in new marketing technologies and support staff to aid our sales force in penetrating existing accounts, lead generation, new Client generation and implementations. We further believe that as market leader, we have a strong, established brand and are uniquely positioned to capitalize on the B2C channel in the future.

   Leverage Existing Sales Channels and Penetrate New Markets

We have developed a highly effective and efficient global distribution network. In our core, traditional markets we are targeting large employers and health plans while simultaneously committing incremental sales and marketing

resources to small medium business (“SMB”) sales channel to increase our penetration within this market. Additionally, we intend to further penetrate the provider market, notably hospitals and group physician practices, as we believe our solution offers these markets an attractive platform from which to generate substantial income by acquiring new patients and to better participate in emerging risk‑sharing and value‑based payment models, such as Accountable Care Organizations and Patient‑Centered Medical Homes. Most recently, we made a significant advancement into international markets through our acquisition of Best Doctors. This international Client base, largely comprised of global financial services companies, provides fertile ground for expansion of our product portfolio through existing partners in attractive markets where our infrastructure is already in place. We have preliminarily embarked on exploring the global expansion of telehealth through this new distribution network.

   Expand Across Care Settings & Use Cases

We intend to expand our solution across use cases and additional care settings. In particular, we plan to leverage our newly acquired Best Doctors network to significantly expand our scope. We also continually explore ancillary opportunities to broaden our business. We believe our services have wide applicability across new use cases, including home care, post discharge, wellness/screening and new areas in chronic care. We are also currently extending or have already offered to our Members additional range and functionality of our benefits applications, and will continue to respond quickly to evolving market needs with innovative solutions, including mobile applications, biometric devices and at‑home testing.

 Expand Through Focused Acquisitions

We plan to continue to leverage our know‑how and the scale of our platform to selectively pursue acquisitions. To date, we have completed six acquisitions that have expanded our distribution capabilities and broadened our service offering, including into areas such as behavioral health. Our acquisition strategy is centered on acquiring products, capabilities, clinical specialties, technologies and distribution channels that are highly scalable and rapidly growing. We will continue to evaluate and pursue acquisition opportunities that are complementary to our business.

Technology and Operations

Our integrated technology platform supports rapid and efficient access to, and evaluation of, information from a variety of healthcare network participants. It has a user friendly interface designed to empower Members and dependents to remotely access healthcare whenever and wherever each individual chooses (via mobile devices, the Internet, video and phone).

Our enterprise scale platform is architected for sharing clinical and non clinical data in real time among the Teladoc constituents, which include: Members, Providers, provider network operations centers staff, nurses, SureScripts (for electronic medication prescription writing, routing and fulfillment) and health plans for real time Member eligibility verification , financial responsibility calculations, claims processing, clinical summaries and clinical alerts.

The Teladoc Provider network leverages our technology platform for managing custom visit queues that automatically and instantly route requested visits to the appropriate Providers based upon proprietary algorithms. Providers use our Internet based application or iOs app for viewing their visit queue, scheduling visits and following the proprietary Teladoc workflow for reviewing Members’ medical history and symptoms, documenting the completed visits, e Prescribing, if appropriate, and sending applicable medical content with follow up instructions to the Member via a secure message center.

We use data and analytics to predict demand patterns by geography and we recruit and manage our Provider network to meet the demands of our members. Our complex algorithms enable us to effectively manage/allocate supply and onboard Providers to meet demand while maintaining one hour guaranteed response times, with a median response time of less than ten minutes.

Additionally, our platform’s external connectivity and easy integration with EMR and outside systems extends its functionality and customer features, which include:

REST is a stateless, scalable web services architecture that utilizes open communication standards such as HTTP and HTTPS, and has been widely adopted for system to system communications. Having a documented set of RESTful API’s enables our Clients and Members to access our solution using a custom or existing website or mobile app. For example, a Teladoc health plan Client can offer its Members the ability to access our solution through their existing Member portal. Members can also register for Teladoc, complete their medical history, select a pharmacy and request a visit without having to access the Teladoc Member site. All of these functions are provided via the Client’s website or mobile app that completes system calls to the Teladoc API to process the requests.

The following graphic displays our robust technology architecture that supports our proprietary platforms that service our lines of business:

The primary goal of our integrated platform architecture is to provide a single member experience for our clients whether they have purchased one or several of our service offerings. This is accomplished via an enterprise services based architecture that isolates functional capabilities into independent, standalone service pods that can be accessed by our member facing web and mobile properties. These services can also be accessed by partners that desire tighter integrations with seamless experiences for their members through Single Sign on (SSO), our SDK and our APIs. These pods can be independently managed and scaled to meet varying usage requirements.

We host portions of our application platforms and rely on cloud partners for our infrastructure to serve our users. For the non-cloud based infrastructure, we utilize two redundant data centers in geographically diverse locations. We rely on third party vendors to operate these data centers, which are designed to host computer systems that require high levels of availability and have redundant subsystems and compartmentalized security zones. We utilize commercially available hardware for our data center servers. Due to the sensitive nature of our Members and Clients’ data, we have a heightened focus on data security and protection. We have a rigorous and comprehensive information security program managed by a dedicated department of security engineers and analysts. We have implemented telehealth industry standard processes, policies and tools through all levels of our software development and network administration, including regularly scheduled vulnerability scanning and third party penetration testing in order to reduce the risk of vulnerabilities in our system. On an annual basis, we also undergo independent, third party HIPAA and SSAE 16 audits, and we achieved HiTRUST certification in 2017 (https://hitrustalliance.net/).

Systems are actively monitored for any signs of unusual behavior and preemptive action is taken when necessary. Encrypted backup files are transmitted over secure connections to a redundant server storage device in a secondary data center. Our data center facilities employ advanced measures to ensure physical integrity, including redundant power and cooling systems, advanced fire and flood prevention, and 24x7 security guards.

We have also successfully grown our business to a level that supports the establishment of three Teladoc owned provider network operations centers that were opened in December 2016 (Phoenix, AZ) and August 2015 (Lewisville, TX) as well as in July 2017 (Quincy, MA) as a result of the Best Doctors acquisition. Through these internal operations centers, our employees service Teladoc Members and Clients with expanded customer service, compliance monitoring, provider network operations as well as other business support functions.

The three centers operate on a hosted virtual call center platform providing intelligent call routing across the centers for inbound and outbound member and client services in a geo-redundant enterprise 24 X 7 X 365. Through the platform, the centers operate as one in a virtual environment providing better time zone coverage, resource optimization, and disaster recovery roll-over.

Sales and Marketing

We sell our services principally through our direct sales organization. Our direct sales team is comprised of enterprise‑focused field sales professionals who are organized by geography and account size. Our field professionals are supported by a sales operations staff, including product technology experts, lead generation professionals and sales data experts. We maintain relationships with key industry participants including benefit consultants, brokers, group purchasing organizations and health plan and hospital partners.

We generate Client leads, accelerate sales opportunities and build brand awareness through our marketing programs. Our marketing programs target human resource, benefits and finance executives in addition to technology and health professionals, senior business leaders and healthcare channel partners. Our principal marketing programs include use of our website to provide information about our company and our solution, as well as learning opportunities for potential Members; demand generation; field marketing events; integrated marketing campaigns comprised of direct email and online advertising; and participation in industry events, trade shows and conferences.

Clients and Members

Our Clients consist of (i) employers, including 291 Fortune 1000 companies, (ii) health plans and (iii) health systems and other entities. As of December 31, 2017, we had approximately 10,000 Clients and our services reached over 23.2 million Members. The following is a selection of our Clients:

Within existing accounts, we believe our current membership represents only a fraction of the potential Members available to us. For example, our existing health plan Clients and self‑insured Clients associated with these health plans currently purchase our solution for only a small percentage of their beneficiaries in aggregate, reflecting a significant opportunity for membership growth. We believe there are in excess of 50 million potential Members within these existing Clients alone.

Research and Development

Our ability to compete depends, in large part, on our continuous commitment to rapidly introduce new services, technologies, features and functionality. Our product development team, which as of December 31, 2017, consisted of 115 employees, is responsible for the design, development, testing and certification of our solution. In addition, we utilize certain third‑party development services to perform application development and design services. We focus our efforts on developing new products and further enhancing the usability, functionality, reliability, performance and flexibility of our solution.

Competition

We view as our competitors those companies that currently (or in the future will) (i) develop and market telehealth technology (devices and systems) or (ii) provide telehealth, such as the delivery of on‑demand access to healthcare. In the provision of telehealth, competition focuses on, among other factors, experience in operation, customer service, quality of technology and know‑how and reputation. Competitors in the telehealth market include MDLive, Inc., American Well Corporation and Grand Rounds, Inc., among other smaller industry participants.

Teladoc Physicians, P.A.

We contract for our providers’ services through the Services Agreement with Teladoc Physicians, P.A. or Teladoc PA, and, therefore, our telehealth providers are not our employees. Under the Services Agreement, we have agreed to serve, on an exclusive basis, as manager and administrator of Teladoc PA’s non‑medical functions and services related to the provision of the telehealth services by physicians employed by or under contract with Teladoc PA. Teladoc PA has agreed to provide our members, through its physicians, access to telehealth services and recommended treatment 24 hours per day, 365 days per year. The Services Agreement also requires Teladoc PA to maintain the state licensure and other credentialing requirements of its physicians. The non‑medical functions and services we provide under the Services Agreement primarily include member management services such as maintaining network operations centers for our members to request a visit with Teladoc PA’s physicians (our providers), member billing and collection administration and maintenance and storage of member medical records. Under the Services Agreement, Teladoc PA currently pays us an access fee of $25,000 per month for network operations center and medical records maintenance, a fixed fee of $65,000 per month for our provision of management and administrative services and a license fee of $10,000 per month for the non‑exclusive use of the Teladoc trade name. The Services Agreement has a 20‑year term and expires in February 2025 unless earlier terminated upon mutual agreement of the parties or unilaterally by a party following the commencement of bankruptcy or liquidation proceeds by the non‑terminating party, a material breach of the Services

Agreement by the non‑terminating party or a governmental or judicial termination order related to the Services Agreement.

Regulation

For information regarding significant regulation that affects us, refer to “Regulatory Environment” of Management’s Discussion and Analysis of Financial Condition and Results of Operations included in Part II, Item 7 of this Annual Report on Form 10-K, and for a discussion of certain factors that may cause our actual results to differ from currently anticipated results in connection with regulation that affects us, see “Risk Factors” included in Part I, Item 1A of this Annual Report on Form 10-K

OTHER INFORMATION

Employees

As of December 31, 2017, we had 1,231 employees. We consider our relationship with our employees to be good. None of our employees are represented by a labor union or party to a collective bargaining agreement.

Intellectual Property

We own and use trademarks and service marks on or in connection with our services, including both unregistered common law marks and issued trademark registrations in the United States and around the world. We also have trademark applications pending to register marks in the United States and internationally. In addition, we rely on certain intellectual property rights that we license from third parties and on other forms of intellectual property rights and measures, including trade secrets, know‑how and other unpatented proprietary processes and nondisclosure agreements, to maintain and protect proprietary aspects of our products and technologies. Other than the trademarks Teladoc (and design) and Best Doctors (and design), we do not believe our business is dependent to a material degree on trademarks, patents, copyrights or trade secrets. We require our employees, consultants and certain of our contractors to execute confidentiality and proprietary rights agreements in connection with their employment or consulting relationships with us. We also require our employees and consultants to disclose and assign to us all inventions conceived during the term of their employment or engagement while using our property or which relate to our business.

Legal Proceedings

From time to time, Teladoc is involved in various litigation matters arising out of the normal course of business. We consult with legal counsel on those issues related to litigation and seek 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 our business, financial condition, results of operations, 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. Teladoc’s management does not presently expect any litigation matters to have a material adverse impact on our business, financial condition, results of operations or cash flows.

Seasonality

We typically experience the strongest increases in consecutive quarterly revenue during the fourth and first quarters of each year, which coincides with traditional annual benefit enrollment seasons. In particular, as a result of many Clients’ introduction of new services at the very end of a calendar year, or the start of each calendar year, the majority of our new Client contracts have an effective date of January 1. Additionally, as a result of national seasonal cold and flu trends, we experience our highest level of visit fees during the first and fourth quarters of each year when compared to other quarters of the year. Conversely, the second quarter of the year has historically been the period of

lowest utilization of our Provider network services relative to the other quarters of the year. See “Risk Factors—Risks Related to Our Business—Our quarterly results may fluctuate significantly, which could adversely impact the value of our common stock.” included below in this annual report on Form 10-K.

Other

To the extent required by Item 1 of Form 10-K, the information contained in Item 7 of this Annual Report is hereby incorporated by reference in this Item 1.

Item 1A. Risk Factors

Our financial and operating results are subject to many significant risks and uncertainties, as described below. The following is a summary of the material risks known to us. There may be other material risks of which we are unaware.

Risks Related to Our Business

Our business could be adversely affected by legal challenges to our business model or by actions restricting our ability to provide the full range of our services in certain jurisdictions.

Our ability to conduct telehealth services and expert second-opinion reviews in a particular U.S. state or non-U.S. jurisdiction is directly dependent upon the applicable laws governing remote care, the practice of medicine and healthcare delivery in general in such location which are subject to changing political, regulatory and other influences. With respect to telehealth services, in the past, state medical boards have established new rules or interpreted existing rules in a manner that has limited or restricted our ability to conduct our business as it was conducted in other states. Some of these actions have resulted in litigation and the suspension or modification of our telehealth operations in certain states. With respect to expert second-opinion services, we believe we are correct in the view that they do not constitute the practice of medicine in any jurisdiction in which we provide them. However, the extent to which a U.S. state or non-U.S. jurisdiction considers particular actions or relationships to constitute practicing medicine is subject to change and to evolving interpretations by (in the case of U.S. states) medical boards and state attorneys general, among others, and (in the case of non-U.S. jurisdictions) the relevant regulatory and legal authorities, each with broad discretion. Accordingly, we must monitor our compliance with law in every jurisdiction in which we operate, on an ongoing basis, and we cannot provide assurance that our activities and arrangements, if challenged, will be found to be in compliance with the law. Additionally, it is possible that the laws and rules governing the practice of medicine, including remote care, in one or more jurisdictions may change in a manner-deleterious to our business. If a successful legal challenge or an adverse change in the relevant laws were to occur, and we were unable to adapt our business model accordingly, our operations in the affected jurisdictions would be disrupted, which could have a material adverse effect on our business, financial condition and results of operations.

In our U.S. telehealth business, we are dependent on our relationships with affiliated professional entities, which we do not own, to provide physician services, and our business would be adversely affected if those relationships were disrupted.

There is a risk that U.S. state authorities in some jurisdictions may find that our contractual relationships with our physicians providing telehealth violate laws prohibiting the corporate practice of medicine. These laws generally prohibit the practice of medicine by lay persons or entities and are intended to prevent unlicensed persons or entities from interfering with or inappropriately influencing the physician’s professional judgment. The extent to which each state considers particular actions or contractual relationships to constitute improper influence of professional judgment varies across the states and is subject to change and to evolving interpretations by state boards of medicine and state attorneys general, among others. As such, we must monitor our compliance with laws in every jurisdiction in which we operate on an ongoing basis and we cannot guarantee that subsequent interpretation of the corporate practice of medicine laws will not circumscribe our business operations. State corporate practice of medicine doctrines also often impose penalties on physicians themselves for aiding the corporate practice of medicine, which could discourage physicians from participating in our network of providers.

The corporate practice of medicine prohibition exists in some form, by statute, regulation, board of medicine or attorney general guidance, or case law, in at least 42 states, all of which we operate in, though the broad variation between state application and enforcement of the doctrine makes an exact count difficult. Due to the prevalence of the corporate practice of medicine doctrine, including in the states where we predominantly conduct our business, we contract for provider services through a services agreement with Teladoc Physicians, P.A., which is a 100% physician‑owned independent entity that has agreements with several professional corporations, to contract with physicians and professional corporations that contract with physicians for the clinical and professional services provided to our members. We do not own Teladoc Physicians, P.A. or the professional corporations with which it contracts. Teladoc Physicians, P.A. is owned by Dr. Timothy Howard, one of our providers, and the professional corporations are owned by physicians licensed in their respective states. While we expect that these relationships will continue, we cannot guarantee that they will. A material change in our relationship with Teladoc Physicians, P.A., or among Teladoc Physicians, P.A. and the contracted professional corporations, whether resulting from a dispute among the entities, a change in government regulation, or the loss of these affiliations, could impair our ability to provide services to our members and could have a material adverse effect on our business, financial condition and results of operations. In addition, the arrangement in which we have entered to comply with state corporate practice of medicine doctrines could subject us to additional scrutiny by federal and state regulatory bodies regarding federal and state fraud and abuse laws. Any scrutiny, investigation, or litigation with regard to our arrangement with Teladoc Physicians, P.A. could have a material adverse effect on our business, financial condition and results of operations.

Evolving government regulations may require increased costs or adversely affect our results of operations.

In a regulatory climate that is uncertain, our operations may be subject to direct and indirect adoption, expansion or reinterpretation of various laws and regulations. Compliance with these future laws and regulations may require us to change our practices at an undeterminable and possibly significant initial monetary and recurring expense. These additional monetary expenditures may increase future overhead, which could have a material adverse effect on our results of operations.

We have identified what we believe are the areas of government regulation that, if changed, would be costly to us. These include: rules governing the practice of medicine by physicians; licensure standards for doctors and behavioral health professionals; laws limiting the corporate practice of medicine; cybersecurity and privacy laws; laws and rules relating to the distinction between independent contractors and employees; and tax and other laws encouraging employer‑sponsored health insurance and group benefits. There could be laws and regulations applicable to our business that we have not identified or that, if changed, may be costly to us, and we cannot predict all the ways in which implementation of such laws and regulations may affect us.

In the jurisdictions in which we operate, we believe we are in compliance with all applicable laws, but, due to the uncertain regulatory environment, certain jurisdictions may determine that we are in violation of their laws. In the event that we must remedy such violations, we may be required to modify our services and products in a manner that undermines our solution’s attractiveness to our clients, members or providers or experts, we may become subject to fines or other penalties or, if we determine that the requirements to operate in compliance in such jurisdictions are overly burdensome, we may elect to terminate our operations in such places. In each case, our revenue may decline and our business, financial condition and results of operations could be materially adversely affected.

Additionally, the introduction of new services may require us to comply with additional, yet undetermined, laws and regulations. Compliance may require obtaining appropriate licenses or certificates, increasing our security measures and expending additional resources to monitor developments in applicable rules and ensure compliance. The failure to adequately comply with these future laws and regulations may delay or possibly prevent some of our products or services from being offered to clients and members, which could have a material adverse effect on our business, financial condition and results of operations.

In the U.S., we conduct business in a heavily regulated industry and if we fail to comply with these laws and government regulations, we could incur penalties or be required to make significant changes to our operations or experience adverse publicity, which could have a material adverse effect on our business, financial condition, and results of operations.

The U.S. healthcare industry is heavily regulated and closely scrutinized by federal, state and local governments. Comprehensive statutes and regulations govern the manner in which we provide and bill for services and collect reimbursement from governmental programs and private payors, our contractual relationships with our providers, vendors and clients, our marketing activities and other aspects of our operations. Of particular importance are:

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our business activities could be subject to challenge under one or more of such laws. Achieving and sustaining compliance with these laws may prove costly. Failure to comply with these laws and other laws can result in civil and criminal penalties such as fines, damages, overpayment recoupment loss of enrollment status and exclusion from the Medicare and Medicaid programs. The risk of our being found in violation of these laws and regulations is increased by the fact that many of them have not been fully interpreted by the regulatory authorities or the courts, and their provisions are sometimes open to a variety of interpretations. Our failure to accurately anticipate the application of these laws and regulations to our business or any other failure to comply with regulatory requirements could create liability for us and negatively affect our business. Any action against us for violation of these laws or regulations, even if we successfully defend against it, could cause us to incur significant legal expenses, divert our management’s attention from the operation of our business and result in adverse publicity.

To enforce compliance with the federal laws, the U.S. Department of Justice and the U.S. Department of Health and Human Services Office of Inspector General, or OIG, have recently increased their scrutiny of healthcare providers, which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing with investigations can be time‑ and resource‑consuming and can divert management’s attention from the business. Any such investigation or settlement could increase our costs or otherwise have an adverse effect on our business. In addition, because of the potential for large monetary exposure under the federal False Claims Act, which provides for treble damages and mandatory minimum penalties of $5,500 to $11,000 per false claim or statement, healthcare providers often resolve allegations without admissions of liability for significant and material amounts to avoid the uncertainty of treble damages that may be awarded in litigation proceedings. Such settlements often contain additional compliance and reporting requirements as part of a consent decree, settlement agreement or corporate integrity agreement. Given the significant size of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.

The laws, regulations and standards governing the provision of healthcare services may change significantly in the future. We cannot assure you that any new or changed healthcare laws, regulations or standards will not materially adversely affect our business. We cannot assure you that a review of our business by judicial, law enforcement, regulatory or accreditation authorities will not result in a determination that could adversely affect our operations.

Our international operations pose certain risks to our business that may be different from risks associated with our domestic operations.

Our international business is subject to risks resulting from differing legal and regulatory requirements, political, social and economic conditions and unforeseeable developments in a variety of jurisdictions. We have employees in eight countries, offices in the United States, Canada, Spain and Australia and clients across more than 100 countries worldwide. We earned approximately 8% of revenue internationally in 2017. Our international operations following are subject to particular risks in addition to those faced by our domestic operations, including:

Our overall success in international markets depends, in part, on our ability to anticipate and effectively manage these risks and there can be no assurance that we will be able to do so without incurring unexpected costs. If we are not able to manage the risks related to our international operations, our business, financial condition and results of operations may be materially adversely affected.

Our failure to comply with the anti-corruption, trade compliance and economic sanctions laws and

regulations of the United States and applicable international jurisdictions could materially adversely affect our reputation and results of operations.

We must comply with anti-corruption laws and regulations imposed by governments around the world with

jurisdiction over our operations, which may include the U.S. Foreign Corrupt Practices Act of 1977 (the

“FCPA”) and the U.K. Bribery Act 2010 (the “Bribery Act'”), as well as the laws of the countries where we do business. These laws and regulations apply to companies, individual directors, officers, employees and agents, and may restrict our operations, trade practices, investment decisions and partnering activities. Where they apply, the FCPA and the Bribery Act prohibit us and our officers, directors, employees and business partners acting on our behalf, including joint venture partners and agents, from corruptly offering, promising, authorizing or providing anything of value to public officials for the purposes of influencing official decisions or obtaining or retaining business or otherwise obtaining favorable treatment. The Bribery Act also prohibits non-governmental ‘‘commercial'' bribery and accepting bribes. As part of our

business, we may deal with governments and state-owned business enterprises, the employees and representatives of which may be considered public officials for purposes of the FCPA and the Bribery Act.

We also are subject to the jurisdiction of various governments and regulatory agencies around the world, which may bring our personnel and agents into contact with public officials responsible for issuing or renewing permits, licenses or approvals or for enforcing other governmental regulations. In addition, some of the international locations in which we will operate lack a developed legal system and have elevated levels of corruption. Our business also must be conducted in compliance with applicable export controls and trade and economic sanctions laws and regulations, including those of the U.S. government, the governments of other countries in which we will operate or conduct business and various multilateral organizations. Such laws and regulations include, without limitation, those administered and enforced by the U.S. Department of the Treasury's Office of Foreign Assets Control, the U.S. Department of State, the U.S. Department of Commerce, the United Nations Security Council and other relevant sanctions authorities. Our provision of services to persons located outside the United States may be subject to certain regulatory prohibitions, restrictions or other requirements, including certain licensing or reporting requirements. Our provision of services outside of the United States exposes us to the risk of violating, or being accused of violating, anti-corruption, exports controls and trade compliance and economic sanctions laws and regulations. Our failure to successfully comply with these laws and regulations may expose us to reputational harm as well as significant sanctions, including criminal fines, imprisonment, civil penalties, disgorgement of profits, injunctions and suspension or debarment from government contracts, as well as other remedial measures. Investigations of alleged violations can be expensive and disruptive. Though we have implemented formal training and monitoring programs, we cannot assure compliance by our employees or representatives for which we may be held responsible, and any such violation could materially adversely affect our reputation, business, financial condition and results of operations.

Foreign currency exchange rate fluctuations could adversely affect our results of operations.

Our business is exposed to fluctuations in exchange rates. Although our reporting currency is the U.S. dollar, we operate in different geographical areas and transact in a range of currencies in addition to the U.S. dollar. As a result, movements in exchange rates may cause our revenue and expenses to fluctuate, impacting our profitability and cash flows. Future business operations and opportunities, including any continued expansion of our business outside the United States, may further increase the risk that cash flows resulting from these activities may be adversely affected by changes in currency exchange rates. In the event we are unable to offset these risks, there may be a material adverse impact on our business and operations. In appropriate circumstances where we are unable to naturally offset our exposure to these currency risks, we may enter into derivative transactions to reduce such exposures. Even where we implement hedging strategies to mitigate foreign currency risk, these strategies might not eliminate our exposure to foreign exchange rate fluctuations and involve costs and risks of their own, such as ongoing management time and expertise, external costs to implement the strategies and potential accounting implications. Nevertheless, exchange rate fluctuations may either increase or decrease our revenues and expenses as reported in U.S. dollars. Moreover, foreign governments may restrict transfers of cash out of the country and control exchange rates. There can be no assurance that we will be able to repatriate our earnings, and at exchange rates that are beneficial to us, which could have a material adverse effect on our business, financial condition and results of operations.

Our business is subject to complex and evolving foreign laws and regulations regarding privacy, data protection and other matters relating to information collection.

There are numerous foreign laws, regulations and directives regarding privacy and the collection, storage, transmission, use, processing, disclosure and protection of personally identifiable information (“PII”) and other personal or customer data, the scope of which is continually evolving and subject to differing interpretations. We must comply with such laws, regulations and directives and we may be subject to significant consequences, including penalties and fines, for our failure to comply. For example, the European Commission has enacted the General Data Protection Regulation (“GDPR”) that becomes effective in May 2018 and will supersede current European Union data protection legislation, impose more stringent European Union data protection requirements and provide for severe penalties for breach, which could be imposed directly on our European subsidiaries. In addition, recent legal developments in Europe have created complexity and compliance uncertainty regarding certain transfers of information from Europe to the United States. We cannot be certain of the legitimacy of previously authorized data export mechanisms, including

Standard Model Contractual Clauses, on which we and our customers have relied in exporting data to servers located in the United States. If one or more of the legal bases for transferring PII from Europe to the United States is invalidated, or if we are unable to transfer PII between and among countries and regions in which we operate, it could affect the manner in which we provide our services or could adversely affect our financial results. Furthermore, any failure, or perceived failure, by us to comply with or make effective modifications to our policies, or to comply with any federal, state, or international privacy, data-retention or data-protection-related laws, regulations, orders or industry self-regulatory principles could result in proceedings or actions against us by governmental entities or others, a loss of customer confidence, damage to our brand and reputation, and a loss of customers, any of which could have an adverse effect on our business. In addition, various federal, state and foreign legislative or regulatory bodies may enact new or additional laws and regulations concerning privacy, data-retention and data-protection issues, including laws or regulations mandating disclosure to domestic or international law enforcement bodies, which could adversely impact our business, our brand or our reputation with customers. For example, some countries have adopted laws mandating that PII regarding customers in their country be maintained solely in their country. Having to maintain local data centers and redesign product, service and business operations to limit PII processing to within individual countries could increase our operating costs significantly.

As we expand our international operations, we will increasingly face political, legal and compliance, operational, regulatory, economic and other risks that we do not face or are more significant than in our domestic operations. Our exposure to these risks is expected to increase.

As we expand our international operations, we will increasingly face political, legal and compliance, operational, regulatory, economic and other risks that we do not face or that are more significant than in our domestic operations. These risks vary widely by country and include varying regional and geopolitical business conditions and demands, government intervention and censorship, discriminatory regulation, nationalization or expropriation of assets and pricing constraints. Our international products need to meet country-specific client and member preferences as well as country-specific legal requirements, including those related to licensing, privacy, data storage, location, protection and security.

Our international operations increase our exposure to, and require us to devote significant management resources to implement controls and systems to comply with, the privacy and data protection laws of non-U.S. jurisdictions and the anti-bribery, anti-corruption and anti-money laundering laws of the United States (including the FCPA) and the United Kingdom (including the Bribery Act) and similar laws in other jurisdictions. Implementing our compliance policies, internal controls and other systems upon our expansion into new countries and geographies may require the investment of considerable management time and management, financial and other resources over a number of years before any significant revenues or profits are generated. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers or employees, restrictions or outright prohibitions on the conduct of our business, and significant brand and reputational harm. We must regularly reassess the size, capability and location of our global infrastructure and make appropriate changes, and must have effective change management processes and internal controls in place to address changes in our business and operations. Our success depends, in part, on our ability to anticipate these risks and manage these difficulties, and the failure to do so could have a material adverse effect on our business, operating results, financial position, brand, reputation and/or long-term growth.

Our international operations require us to overcome logistical and other challenges based on differing languages, cultures, legal and regulatory schemes and time zones. Our international operations encounter labor laws, customs and employee relationships that can be difficult, less flexible than in our domestic operations and expensive to modify or terminate. In some countries we are required to, or choose to, operate with local business partners, which requires us to manage our partner relationships and may reduce our operational flexibility and ability to quickly respond to business challenges.

We have a history of cumulative losses, which we expect to continue, and we may never achieve or sustain profitability.

We have incurred significant losses in each period since our inception. We incurred net losses of $106.8 million, $74.2 million and $58.0 million for the years ended December 31, 2017, 2016 and 2015, respectively. As of December 31, 2017, we had an accumulated deficit of $311.6 million. These losses and accumulated deficit reflect the substantial investments we made to acquire new clients, build our proprietary network of healthcare providers and develop our technology platform. We intend to continue scaling our business to increase our client, member and provider bases, broaden the scope of services we offer and expand our applications of technology through which members can access our services. Accordingly, we anticipate that cost of revenue and operating expenses will increase substantially in the foreseeable future. These efforts may prove more expensive than we currently anticipate and we may not succeed in increasing our revenue sufficiently to offset these higher expenses. We cannot assure you that we will achieve profitability in the future or that, if we do become profitable, we will be able to sustain or increase profitability. Our prior losses, combined with our expected future losses, have had and will continue to have an adverse effect on our stockholders’ equity and working capital. As a result of these factors, we may need to raise additional capital through debt or equity financings in order to fund our operations, and such capital may not be available on reasonable terms, if at all.

The impact of recent healthcare reform legislation and other changes in the healthcare industry and in healthcare spending on us is currently unknown, but may adversely affect our business, financial condition and results of operations.

Our revenue is dependent on the healthcare industry and could be affected by changes in healthcare spending and policy. The healthcare industry is subject to changing political, regulatory and other influences. The Patient Protection and Affordable Care Act or PPACA made major changes in how healthcare is delivered and reimbursed, and increased access to health insurance benefits to the uninsured and underinsured population of the United States.

The PPACA, among other things, increased the number of individuals with Medicaid and private insurance coverage, implemented reimbursement policies that tie payment to quality, facilitated the creation of accountable care organizations that may use capitation and other alternative payment methodologies, strengthened enforcement of fraud and abuse laws and encouraged the use of information technology.

Such changes in the regulatory environment may also result in changes to our payor mix that may affect our operations and revenue.

In addition, certain provisions of the PPACA authorize voluntary demonstration projects, which include the development of bundling payments for acute, inpatient hospital services, physician services and postacute services for episodes of hospital care. Further, the PPACA may adversely affect payors by increasing medical costs generally, which could have an effect on the industry and potentially impact our business and revenue as payors seek to offset these increases by reducing costs in other areas. The full impact of these changes on us cannot be determined at this time.

We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments and other third‑party payors will pay for healthcare products and services, which could adversely affect our business, financial condition and results of operations.

A significant portion of our revenue comes from a limited number of clients, the loss of which would have a material adverse effect on our business, financial condition and results of operations.

Historically, we have relied on a limited number of clients for a substantial portion of our total revenue. For the year ended December 31, 2017, 2016 and 2015, no client represented more than 10% of our total revenue. For the years ended December 31, 2017, 2016 and 2015, our top ten clients by revenue accounted for 16.0%, 23.9% and 22.9% of our total revenue, respectively. We also rely on our reputation and recommendations from key clients in order to promote our solution to potential new clients. The loss of any of our key clients, or a failure of some of them to renew or expand their subscriptions, could have a significant impact on the growth rate of our revenue, reputation and our ability to obtain new

clients. In addition, mergers and acquisitions involving our clients could lead to cancellation or non‑renewal of our contracts with those clients or by the acquiring or combining companies, thereby reducing the number of our existing and potential clients and members.

The telehealth market is immature and volatile, and if it does not develop, if it develops more slowly than we expect, if it encounters negative publicity or if our solution does not drive member engagement, the growth of our business will be harmed.

With respect to our telehealth services, the telehealth market is relatively new and unproven, and it is uncertain whether it will achieve and sustain high levels of demand, consumer acceptance and market adoption. Our success will depend to a substantial extent on the willingness of our members to use, and to increase the frequency and extent of their utilization of, our solution, as well as on our ability to demonstrate the value of telehealth to employers, health plans, government agencies and other purchasers of healthcare for beneficiaries. Negative publicity concerning our solution or the telehealth market as a whole could limit market acceptence of our solution. If our clients and members do not perceive the benefits of our solution, or if our solution does not drive member engagement, then our market may not develop at all, or it may develop more slowly than we expect. Similarly, individual and healthcare industry concerns or negative publicity regarding patient confidentiality and privacy in the context of telehealth could limit market acceptance of our healthcare services. If any of these events occurs, it could have a material adverse effect on our business, financial condition or results of operations.

If the number of individuals covered by our employer, health plan and other clients decreases, or the number of applications or services to which they subscribe decreases, our revenue will likely decrease.

Under most of our client contracts, we base our fees on the number of individuals to whom our clients provide benefits and the number of applications or services subscribed to by our clients. Many factors may lead to a decrease in the number of individuals covered by our clients and the number of applications or services subscribed to by our clients, including, but not limited to, the following:

If the number of individuals covered by our employer, health plan and other clients decreases, or the number of applications or services to which they subscribe decreases, for any reason, our revenue will likely decrease.

Our growth depends in part on the success of our strategic relationships with third parties.

In order to grow our business, we anticipate that we will continue to depend on our relationships with third parties, including our partner organizations and technology and content providers. For example, we partner with a number of price transparency, health savings account, or HSA and other benefits platforms to deliver our solution to their consumers. Identifying partners, and negotiating and documenting relationships with them, requires significant time and resources. Our competitors may be effective in providing incentives to third parties to favor their products or services or to prevent or reduce subscriptions to, or utilization of, our products and services. In addition, acquisitions of our partners by our competitors could result in a decrease in the number of our current and potential clients, as our partners may no longer facilitate the adoption of our applications by potential clients. If we are unsuccessful in establishing or maintaining our relationships with third parties, our ability to compete in the marketplace or to grow our revenue could be impaired and our results of operations may suffer. Even if we are successful, we cannot assure you that these relationships will result in increased client use of our applications or increased revenue.

Our telehealth business and growth strategy depend on our ability to maintain and expand a network of qualified providers. If we are unable to do so, our future growth would be limited and our business, financial condition and results of operations would be harmed.

Our success is dependent upon our continued ability to maintain a network of qualified telehealth providers. If we are unable to recruit and retain board‑certified physicians and other healthcare professionals, it would have a material adverse effect on our business and ability to grow and would adversely affect our results of operations. In any particular market, providers could demand higher payments or take other actions that could result in higher medical costs, less attractive service for our clients or difficulty meeting regulatory or accreditation requirements. Our ability to develop and maintain satisfactory relationships with providers also may be negatively impacted by other factors not associated with us, such as changes in Medicare and/or Medicaid reimbursement levels and other pressures on healthcare providers and consolidation activity among hospitals, physician groups and healthcare providers. The failure to maintain or to secure new cost‑effective provider contracts may result in a loss of or inability to grow our membership base, higher costs, healthcare provider network disruptions, less attractive service for our clients and/or difficulty in meeting regulatory or accreditation requirements, any of which could have a material adverse effect on our business, financial condition and results of operations.

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 common stock.

We have experienced significant growth in the last five years. Future revenues may not grow at these same rates or may decline. 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 and member bases, to develop new products and 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 would indicate future growth, we will continue to grow our revenue or to generate 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, our existing clients may be slower to adopt our services than we currently anticipate, which could adversely affect our results of operations and growth prospects.

We may become subject to medical liability claims, which could cause us to incur significant expenses and may require us to pay significant damages if not covered by insurance.

Our business entails the risk of medical liability claims against both our providers and us. Although we and Teladoc Physicians, P.A. carry insurance covering medical malpractice claims in amounts that we believe are appropriate in light of the risks attendant to our business, successful medical liability claims could result in substantial damage awards that exceed the limits of our and Teladoc Physicians, P.A.’s insurance coverage. Teladoc Physicians, P.A. carries professional liability insurance for itself and each of its healthcare professionals (our providers), and we separately carry a general insurance policy, which covers medical malpractice claims. In addition, professional liability insurance is expensive and insurance premiums may increase significantly in the future, particularly as we expand our services. As a result, adequate professional liability insurance may not be available to our providers or to us in the future at acceptable costs or at all.

Any claims made against us that are not fully covered by insurance could be costly to defend against, result in substantial damage awards against us and divert the attention of our management and our providers from our operations, which could have a material adverse effect on our business, financial condition and results of operations. In addition, any claims may adversely affect our business or reputation.

Rapid technological change in our industry presents us with significant risks and challenges.

The telehealth market is characterized by rapid technological change, changing consumer requirements, short product lifecycles and evolving industry standards. Our success will depend on our ability to enhance our solution with

next‑generation technologies and to develop or to acquire and market new services to access new consumer populations. There is no guarantee that we will possess the resources, either financial or personnel, for the research, design and development of new applications or services, or that we will be able to utilize these resources successfully and avoid technological or market obsolescence. Further, there can be no assurance that technological advances by one or more of our competitors or future competitors will not result in our present or future applications and services becoming uncompetitive or obsolete.

A decline in the prevalence of employer‑sponsored healthcare or the emergence of new technologies may render our telehealth solution obsolete or require us to expend significant resources in order to remain competitive.

The U.S. healthcare industry is massive, with a number of large market participants with conflicting agendas, is subject to significant government regulation and is currently undergoing significant change. Changes in our industry, for example, away from high‑deductible health plans, or the emergence of new technologies as more competitors enter our market, could result in our telehealth solution being less desirable or relevant.

For example, we currently derive the majority of our revenue from sales to clients that purchase healthcare for their employees (either via insurance or self‑funded benefit plans). A large part of the demand for our solution depends on the need of these employers to manage the costs of healthcare services that they pay on behalf of their employees. Some experts have predicted that future healthcare reform will encourage employer‑sponsored health insurance to become significantly less prevalent as employees migrate to obtaining their own insurance over the state‑sponsored insurance marketplaces. Were this to occur, there is no guarantee that we would be able to compensate for the loss in revenue from employers by increasing sales of our solution to health insurance companies or to individuals or government agencies. In such a case, our results of operations would be adversely affected.

If healthcare benefits trends shift or entirely new technologies are developed that replace existing solutions, our existing or future solutions could be rendered obsolete and our business could be adversely affected. In addition, we may experience difficulties with software development, industry standards, design or marketing that could delay or prevent our development, introduction or implementation of new applications and enhancements.

If our new applications and services are not adopted by our clients, or if we fail to innovate and develop new applications and services that are adopted by our clients, our revenue and results of operations will be adversely affected.

To date, we have derived a substantial majority of our revenue from sales of our primary care telehealth and expert second-opinion solutions, and our longer‑term results of operations and continued growth will depend on our ability successfully to develop and market new applications and services that our clients want and are willing to purchase. In addition, we have invested, and will continue to invest, significant resources in research and development to enhance our existing solution and introduce new high‑quality applications and services. If existing clients are not willing to make additional payments for such new applications, or if new clients and members do not value such new applications, it could have a material adverse effect on our business, financial condition and results of operations. If we are unable to predict user preferences or if our industry changes, or if we are unable to modify our solution and services on a timely basis, we may lose clients. Our results of operations would also suffer if our innovations are not responsive to the needs of our clients, appropriately timed with market opportunity or effectively brought to market.

We rely on data center providers, Internet infrastructure, bandwidth providers, third‑party computer hardware and software, other third parties and our own systems for providing services to our clients and members, and any failure or interruption in the services provided by these third parties or our own systems could expose us to litigation and negatively impact our relationships with clients, adversely affecting our brand and our business.

We serve all of our clients and members from seven geographically dispersed data centers. While we control and have access to our servers, we do not control the operation of these facilities. The owners of our data center facilities have no obligation to renew their agreements with us on commercially reasonable terms, or at all. If we are unable to renew these agreements on commercially reasonable terms, or if one of our data center operators is acquired, we may be required to transfer our servers and other infrastructure to new data center facilities, and we may incur significant costs

and possible service interruption in connection with doing so. Problems faced by our third‑party data center locations with the telecommunications network providers with whom we or they 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 members. Our third‑party data center operators could decide to close their facilities without adequate notice. In addition, any financial difficulties, such as bankruptcy faced by our third‑party data centers operators or any of the service providers with whom we or they contract may have negative effects on our business, the nature and extent of which are difficult to predict.

Additionally, if our data centers are unable to keep up with our growing needs for capacity, this could have an adverse effect on our business. For example, a rapid expansion of our business could affect the service levels at our data centers or cause such data centers and systems to fail. Any changes in third‑party service levels at our data centers or any disruptions or other performance problems with our solution could adversely affect our reputation and may damage our clients and members’ stored files or result in lengthy interruptions in our services. Interruptions in our services may reduce our revenue, cause us to issue refunds to clients for prepaid and unused subscriptions, subject us to potential liability or adversely affect client renewal rates.

In addition, our ability to deliver our Internet‑based services depends on the development and maintenance of the infrastructure of the Internet by third parties. This includes maintenance of a reliable network backbone 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. However, we have experienced and expect that we may experience future interruptions and delays in services and availability from time to time. In the event of a catastrophic event with respect to one or more of our systems, we may experience an extended period of system unavailability, which could negatively impact our relationship with clients and members. To operate without interruption, both we and our service providers must guard against:

We also rely on computer hardware purchased or leased and software licensed from third parties in order to offer our services, including software from Dell Computer, Microsoft, Apple and Redhat Corporation, and routers and network equipment from Cisco and Hewlett‑Packard Company. These licenses are generally commercially available on varying terms. However, it is possible that this hardware and software may not continue to be available on commercially reasonable terms, or at all. Any loss of the right to use any of this hardware or software could result in delays in the provisioning of our services until equivalent technology is either developed by us, or, if available, is identified, obtained and integrated.

We exercise limited control over third‑party vendors, which increases our vulnerability to problems with technology and information services they provide. Interruptions in our network access and services may in connection with third‑party technology and information services reduce our revenue, cause us to issue refunds to clients for prepaid and unused subscription services, subject us to potential liability or adversely affect client renewal rates. Although we maintain a security and privacy damages insurance policy, the coverage under our policies may not be adequate to compensate us for all losses that may occur related to the services provided by our third‑party vendors. In addition, we may not be able to continue to obtain adequate insurance coverage at an acceptable cost, if at all.

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’ and our members’ proprietary information, sensitive or confidential data, including valuable intellectual property and personal information of employees, clients, members and others, as well as the protected health information, or PHI, of our members. 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 further enhance our information security measures and/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 member 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, member 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 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. 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, clients and members, which could have a material adverse effect on our business, operations, and financial results.

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 Internet and technology 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 sole primary business is to assert such claims. Regardless of the merits of any other intellectual property litigation, we may be required to expend significant management time and financial resources on the defense of such claims, and any adverse outcome of any such claim or the above referenced review could have a material adverse effect on our business, financial condition or results of operations. We expect that we may receive in the future notices that claim we or our clients using our solution have misappropriated or misused other parties’ intellectual property rights, particularly as the number of competitors in our market grows and the functionality of applications amongst competitors overlaps. Our existing or any future 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.

In addition, in most instances, we have agreed to indemnify our clients against certain third‑party claims, which may include claims that our solution infringes the intellectual property rights of such third parties. 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 may become a party, or for which we are required to provide indemnification, may require us to do one or more of the following:

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 could experience losses or liability not covered by insurance.

Our business exposes us to risks that are inherent in the provision of telehealth and remote, virtual healthcare. 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 solution. 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.

If our arrangements with our providers or our clients are found to violate state laws prohibiting the corporate practice of medicine or fee splitting, our business, financial condition and our ability to operate in those states could be adversely impacted.

The laws of many states, including states in which our clients are located, prohibit us from exercising control over the medical judgments or decisions of physicians and from engaging in certain financial arrangements, such as splitting professional fees with physicians. These laws and their interpretations vary from state to state and are enforced by state courts and regulatory authorities, each with broad discretion. We enter into agreements with a professional association, Teladoc Physicians, P.A., which enters into contracts with our providers pursuant to which they render professional medical services. In addition, we enter into contracts with our clients to deliver professional services in exchange for fees. These contracts include management services agreements with our affiliated physician organizations pursuant to which the physician organizations reserve exclusive control and responsibility for all aspects of the practice of medicine and the delivery of medical services. Although we seek to substantially comply with applicable state prohibitions on the corporate practice of medicine and fee splitting, state officials who administer these laws or other third parties may successfully challenge our existing organization and contractual arrangements. If such a claim were successful, we could be subject to civil and criminal penalties and could be required to restructure or terminate the applicable contractual arrangements. A determination that these arrangements violate state statutes, or our inability to successfully restructure our relationships with our providers to comply with these statutes, could eliminate clients located in certain states from the market for our services, which would have a materially adverse effect on our business, financial condition and results of operations.

If our providers or experts are characterized as employees, we would be subject to employment and withholding liabilities.

We structure our relationships with our providers and experts in a manner that we believe results in an independent contractor relationship, not an employee relationship. An independent contractor is generally distinguished

from an employee by his or her degree of autonomy and independence in providing services. A high degree of autonomy and independence is generally indicative of a contractor relationship, while a high degree of control is generally indicative of an employment relationship. Although we believe that our providers and experts are properly characterized as independent contractors, tax or other regulatory authorities may in the future challenge our characterization of these relationships. If such regulatory authorities or state, federal or foreign courts were to determine that our providers or experts are employees, and not independent contractors, we would be required to withhold income taxes, to withhold and pay social security, Medicare and similar taxes and to pay unemployment and other related payroll taxes. We would also be liable for unpaid past taxes and subject to penalties. As a result, any determination that our providers or experts are our employees could have a material adverse effect on our business, financial condition and results of operations.

Any future litigation against us could be costly and time‑consuming to defend.

We may become subject, from time to time, to legal proceedings and claims that arise in the ordinary course of business such as claims brought by our clients in connection with commercial disputes or employment claims made by our current or former associates. Litigation may result in substantial costs and may divert management’s attention and resources, which may substantially harm our business, financial condition and results of operations. Insurance may not cover such claims, may not provide sufficient payments to cover all of the costs to resolve one or more such claims and may not continue to be available on terms acceptable to us. A claim brought against us that is uninsured or underinsured could result in unanticipated costs, thereby reducing our revenue and leading analysts or potential investors to reduce their expectations of our performance, which could reduce the market price of our stock.

Certain U.S. state tax authorities may assert that we have a state nexus and seek to impose state and local income taxes which could adversely affect our results of operations.

We are currently licensed to operate in all fifty states and file state income tax returns in 36 states. There is a risk that certain state tax authorities where we do not currently file a state income tax return could assert that we are liable for state and local income taxes based upon income or gross receipts allocable to such states. States are becoming increasingly aggressive in asserting a nexus for state income tax purposes. We could be subject to state and local taxation, including penalties and interest attributable to prior periods, if a state tax authority successfully asserts that our activities give rise to a nexus. Such tax assessments, penalties and interest may adversely affect our results of operations.

Our ability to use our net operating losses to offset future taxable income may be subject to certain limitations.

In general, under Section 382 of the U.S. Internal Revenue Code of 1986, as amended, or the Code, a corporation that undergoes an “ownership change” is subject to limitations on its ability to utilize its pre‑change net operating losses, or NOLs, to offset future taxable income. A Section 382 “ownership change” generally occurs if one or more stockholders or groups of stockholders who own at least 5% of our stock increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three‑year period. Similar rules may apply under state tax laws. As of December 31, 2017, we have approximately $400.5 million of federal net operating loss carryforwards and $193.5 million of state net operating loss carryforwards. The federal net operating loss carryforwards begin to expire in 2025 and the state net operating loss carryforwards begin to expire in 2021.  As of December 31, 2017, the Company has approximately $7.1 million of foreign tax credits, which begin to expire in 2022. Our ability to utilize NOLs may be currently subject to limitations due to a prior ownership changes. In addition, future changes in our stock ownership, some of which are outside of our control, could result in an ownership change under Section 382 of the Code, further limiting our ability to utilize NOLs arising prior to such ownership change in the future. There is also a risk that due to regulatory changes, such as suspensions on the use of NOLs, or other unforeseen reasons, our existing NOLs could expire or otherwise be unavailable to offset future income tax liabilities. We have recorded a full valuation allowance against the deferred tax assets attributable to our NOLs.

Our proprietary software may not operate properly, which could damage our reputation, give rise to claims against us or divert application of our resources from other purposes, any of which could harm our business, financial condition and results of operations.

The Teladoc proprietary application platform provides our members and providers with the ability to, among other things, register for our services; complete, view and edit medical history; request a visit (either scheduled or on demand); conduct a visit (via video or phone); and initiate an expert second-opinion review. Proprietary software development is time‑consuming, expensive and complex, and may involve unforeseen difficulties. We may encounter technical obstacles, and it is possible that we may discover additional problems that prevent our proprietary applications from operating properly. We are currently implementing software with respect to a number of new applications and services. If our solution does not function reliably or fails to achieve client expectations in terms of performance, clients could assert liability claims against us or attempt to cancel their contracts with us. This could damage our reputation and impair our ability to attract or maintain clients.

Moreover, data services are complex and those we offer have in the past contained, and may in the future develop or contain, undetected defects or errors. Material performance problems, defects or errors in our existing or new software and applications and services may arise in the future and may result from interface of our solution with systems and data that we did not develop and the function of which is outside of our control or undetected in our testing. These defects and errors, and any failure by us to identify and address them, could result in loss of revenue or market share, diversion of development resources, harm to our reputation and increased service and maintenance costs. Defects or errors may discourage existing or potential clients from purchasing our solution from us. Correction of defects or errors could prove to be impossible or impracticable. The costs incurred in correcting any defects or errors may be substantial and could have a material adverse effect on our business, financial condition and results of operations.

In order to support the growth of our business, we may need to incur additional indebtedness under our current credit facility or seek capital through new equity or debt financings, which sources of additional capital may not be available to us on acceptable terms or at all.

Our operations have consumed substantial amounts of cash since inception and we intend to continue to make significant investments to support our business growth, respond to business challenges or opportunities, develop new applications and services, enhance our existing solution and services, enhance our operating infrastructure and potentially acquire complementary businesses and technologies. For the years ended December 31, 2017, 2016 and 2015, our net cash used in operating activities was $34.4 million, $51.9 million and $47.2 million respectively. As of December 31, 2017, we had $42.8 million of cash and cash equivalents and $79.5 million of short-term investments, which are held for working capital purposes. As of December 31, 2017, we had borrowings of $275 million of 3% convertible senior notes due 2022 (the “2022 Notes”) and the ability to borrow up to an additional $10.0 million under our credit facilities.

Borrowings under the 2022 Notes are senior unsecured obligations of ours and generally rank senior in right of payment to all of our other unsecured indebtedness. Under certain conditions, we may redeem any portion of the 2022 Notes for cash on or after December 22, 2020. The redemption price will be the principal amount of the 2022 Notes to be redeemed, plus accrued and unpaid interest, if any.

Borrowings under our credit facility is secured by substantially all of our properties, rights and assets. Additionally, the credit agreement governing our credit facility contains certain customary restrictive covenants that limit our ability to incur additional indebtedness and liens, merge with other companies or consummate certain changes of control, acquire other companies, engage in new lines of business, make certain investments, pay dividends and transfer or dispose of assets as well as a financial covenant that requires us to maintain a specified level of recurring revenue growth. These covenants could limit our ability to seek capital through the incurrence of new indebtedness or, if we are unable to meet our recurring revenue growth obligation, require us to repay any outstanding amounts with sources of capital we may otherwise use to fund our business, operations and strategy.

Our future capital requirements may be significantly different from our current estimates and will depend on many factors, including our growth rate, subscription renewal activity, the timing and extent of spending to support

development efforts, the expansion of sales and marketing activities, the introduction of new or enhanced services and the continuing market acceptance of telehealth. Accordingly, we may need to engage in equity or debt financings or collaborative arrangements to secure additional funds. If we raise additional funds through further issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our common stock. Any debt financing secured by us in the future could involve additional restrictive covenants relating to our capital‑raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. In addition, during times of economic instability, it has been difficult for many companies to obtain financing in the public markets or to obtain debt financing, and we may not be able to obtain additional financing on commercially reasonable terms, if at all. If we are unable to obtain adequate financing or financing on terms satisfactory to us, it could have a material adverse effect on our business, financial condition and results of operations.

Failure to adequately expand our direct sales force will impede our growth.

We believe that our future growth will depend on the continued development of our direct sales force and its ability to obtain new clients and to manage our existing client base. Identifying and recruiting qualified personnel and training them requires significant time, expense and attention. It can take six months or longer before a new sales representative is fully trained and productive. Our business may be adversely affected if our efforts to expand and train our direct sales force do not generate a corresponding increase in revenue. In particular, if we are unable to hire and develop sufficient numbers of productive direct sales personnel or if new direct sales personnel are unable to achieve desired productivity levels in a reasonable period of time, sales of our services will suffer and our growth will be impeded.

We may be unable to successfully execute on our growth initiatives, business strategies or operating plans.

We are continually executing a number of growth initiatives, strategies and operating plans designed to enhance our business. For example, we recently entered into new specialist healthcare professional markets as well as into business-to-consumer markets. The anticipated benefits from these efforts are based on several assumptions that may prove to be inaccurate. Moreover, we may not be able to successfully complete these growth initiatives, strategies and operating plans and realize all of the benefits, including growth targets and cost savings, that we expect to achieve or it may be more costly to do so than we anticipate. A variety of risks could cause us not to realize some or all of the expected benefits. These risks include, among others, delays in the anticipated timing of activities related to such growth initiatives, strategies and operating plans, increased difficulty and cost in implementing these efforts, including difficulties in complying with new regulatory requirements and the incurrence of other unexpected costs associated with operating the business. Moreover, our continued implementation of these programs may disrupt our operations and performance. As a result, we cannot assure you that we will realize these benefits. If, for any reason, the benefits we realize are less than our estimates or the implementation of these growth initiatives, strategies and operating plans adversely affect our operations or cost more or take longer to effectuate than we expect, or if our assumptions prove inaccurate, our business, financial condition and results of operations may be materially adversely affected.

Our use and disclosure of personally identifiable information, including health information, is subject to federal and state privacy and security regulations, and our failure to comply with those regulations or to adequately secure the information we hold could result in significant liability or reputational harm and, in turn, a material adverse effect on our client base, membership base and revenue.

Numerous state and federal laws and regulations govern the collection, dissemination, use, privacy, confidentiality, security, availability and integrity of PII, including protected health information. These laws and regulations include HIPAA . HIPAA establishes a set of basic national privacy and security standards for the protection of PHI, by health plans, healthcare clearinghouses and certain healthcare providers, referred to as covered entities, and the business associates with whom such covered entities contract for services, which includes us.

HIPAA requires healthcare providers like us to develop and maintain policies and procedures with respect to PHI that is used or disclosed, including the adoption of administrative, physical and technical safeguards to protect such

information. HIPAA also implemented the use of standard transaction code sets and standard identifiers that covered entities must use when submitting or receiving certain electronic healthcare transactions, including activities associated with the billing and collection of healthcare claims.

HIPAA imposes mandatory penalties for certain violations. Penalties for violations of HIPAA and its implementing regulations start at $100 per violation and are not to exceed $50,000 per violation, subject to a cap of $1.5 million for violations of the same standard in a single calendar year. However, a single breach incident can result in violations of multiple standards. HIPAA also authorizes state attorneys general to file suit on behalf of their residents. Courts will be able to award damages, costs and attorneys’ fees related to violations of HIPAA in such cases. While HIPAA does not create a private right of action allowing individuals to sue us in civil court for violations of HIPAA, its standards have been used as the basis for duty of care in state civil suits such as those for negligence or recklessness in the misuse or breach of PHI.

In addition, HIPAA mandates that the Secretary of Health and Human Services, or HHS conduct periodic compliance audits of HIPAA covered entities or business associates for compliance with the HIPAA Privacy and Security Standards. It also tasks HHS with establishing a methodology whereby harmed individuals who were the victims of breaches of unsecured PHI may receive a percentage of the Civil Monetary Penalty fine paid by the violator.

HIPAA further requires that patients be notified of any unauthorized acquisition, access, use or disclosure of their unsecured PHI that compromises the privacy or security of such information, with certain exceptions related to unintentional or inadvertent use or disclosure by employees or authorized individuals. HIPAA specifies that such notifications must be made “without unreasonable delay and in no case later than 60 calendar days after discovery of the breach.” If a breach affects 500 patients or more, it must be reported to HHS without unreasonable delay, and HHS will post the name of the breaching entity on its public web site. Breaches affecting 500 patients or more in the same state or jurisdiction must also be reported to the local media. If a breach involves fewer than 500 people, the covered entity must record it in a log and notify HHS at least annually.

Numerous other federal and state laws protect the confidentiality, privacy, availability, integrity and security of personally identifiable information, or PII, including PHI. These laws in many cases are more restrictive than, and may not be preempted by, the HIPAA rules and may be subject to varying interpretations by courts and government agencies, creating complex compliance issues for us and our clients and potentially exposing us to additional expense, adverse publicity and liability.

New health information standards, whether implemented pursuant to HIPAA, congressional action or otherwise, could have a significant effect on the manner in which we must handle healthcare related data, and the cost of complying with standards could be significant. If we do not comply with existing or new laws and regulations related to PHI, we could be subject to criminal or civil sanctions.

Because of the extreme sensitivity of the PII we store and transmit, the security features of our technology platform are very important. If our security measures, some of which are managed by third parties, are breached or fail, unauthorized persons may be able to obtain access to sensitive client and member data, including HIPAA‑regulated PHI. As a result, our reputation could be severely damaged, adversely affecting client and member confidence. Members may curtail their use of or stop using our services or our client base could decrease, which would cause our business to suffer. In addition, we could face litigation, damages for contract breach, penalties and regulatory actions for violation of HIPAA and other applicable laws or regulations and significant costs for remediation, notification to individuals and for measures to prevent future occurrences. Any potential security breach could also result in increased costs associated with liability for stolen assets or information, repairing system damage that may have been caused by such breaches, incentives offered to clients or other business partners in an effort to maintain our business relationships after a breach and implementing measures to prevent future occurrences, including organizational changes, deploying additional personnel and protection technologies, training employees and engaging third‑party experts and consultants. While 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 outsource important aspects of the storage and transmission of client and member information, and thus rely on third parties to manage functions that have material cyber‑security risks. We attempt to address these risks by requiring outsourcing subcontractors who handle client and member information to sign business associate agreements contractually requiring those subcontractors to adequately safeguard personal health data to the same extent that applies to us and in some cases by requiring such outsourcing subcontractors to undergo third‑party security examinations. In addition, we periodically hire third‑party security experts to assess and test our security posture. However, we cannot assure you that these contractual measures and other safeguards will adequately protect us from the risks associated with the storage and transmission of client and members’ proprietary and protected health information.

We also publish statements to our members that describe how we handle and protect personal information. If federal or state regulatory authorities or private litigants consider any portion of these statements to be untrue, we may be subject to claims of deceptive practices, which could lead to significant liabilities and consequences, including, without limitation, costs of responding to investigations, defending against litigation, settling claims and complying with regulatory or court orders.

We also send short message service, or SMS text messages to potential end users who are eligible to use our service through certain customers and partners. While we obtain consent from or on behalf of these individuals to send text messages, federal or state regulatory authorities or private litigants may claim that the notices and disclosures we provide, form of consents we obtain or our SMS texting practices, are not adequate. These SMS texting campaigns are potential sources of risk for class action lawsuits and liability for our company. Numerous class‑action suits under federal and state laws have been filed in the past year against companies who conduct SMS texting programs, with many resulting in multi‑million dollar settlements to the plaintiffs. Any future such litigation against us could be costly and time‑consuming to defend.

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

Our quarterly results of operations, including our revenue, gross profit, net loss and cash flows, has varied and may vary significantly in the future, and period‑to‑period comparisons of our results of operations may not be meaningful. Accordingly, our quarterly results should not be relied upon as an indication of future performance. Our quarterly financial results may fluctuate as a result of a variety of factors, many of which are outside of our control, including, without limitation, the following:

We are particularly subject to fluctuations in our quarterly results of operations because the costs associated with entering into client contracts are generally incurred up front, while we generally recognize revenue over the term of the contract. Further, most of our revenue in any given quarter is derived from contracts entered into with our clients during previous quarters. Consequently, a decline in new or renewed contracts 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 solution, and potential changes in our rate of renewals or renewal terms, may not be fully reflected in our results of operations until future periods. Our subscription model also makes it difficult for us to rapidly increase our total revenue through additional sales in any period, with the exception of the first quarter during peak benefits enrollment, as revenue from new clients must be recognized over the applicable term of the contract. Accordingly, 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. Any fluctuation in our quarterly results may not accurately reflect the underlying performance of our business and could cause a decline in the trading price of our common stock.

If we fail to manage our growth effectively, our expenses could increase more than expected, our revenue may not increase and we may be unable to implement our business strategy.

We have experienced significant growth in recent periods, which puts strain on our business, operations and employees. For example, we grew from 670 full‑time employees at December 31, 2016 to 1,231 full‑time employees at December 31, 2017. We have also increased our client and membership bases significantly over the past two years. We anticipate that our operations will continue to rapidly expand. To manage our current and anticipated future growth effectively, we must continue to maintain and enhance our IT infrastructure, financial and accounting systems and controls. We must also attract, train and retain a significant number of qualified sales and marketing personnel, customer support personnel, professional services personnel, software engineers, technical personnel and management personnel, and the availability of such personnel, in particular software engineers, may be constrained.

A key aspect to managing our growth is our ability to scale our capabilities to implement our solution satisfactorily with respect to both large and demanding clients, who currently constitute the substantial majority of our client base, as well as smaller clients who are becoming an increasingly larger portion of our client base. Large clients often require specific features or functions unique to their membership base, which, at a time of significant growth or during periods of high demand, may strain our implementation capacity and hinder our ability to successfully implement our solution to our clients in a timely manner. We may also need to make further investments in our technology and automate portions of our solution or services to decrease our costs. If we are unable to address the needs of our clients or members, or our clients or members are unsatisfied with the quality of our solution or services, they may not renew their contracts, seek to cancel or terminate their relationship with us or renew on less favorable terms, any of which could cause our annual net dollar retention rate to decrease.

Failure to effectively manage our growth could also lead us to over‑invest or under‑invest in development and operations, result in weaknesses in our infrastructure, systems or controls, give rise to operational mistakes, financial losses, loss of productivity or business opportunities and result in loss of employees and reduced productivity of remaining employees. Our growth is expected to require significant capital expenditures and may divert financial resources from other projects such as the development of new applications and services. If our management is unable to effectively manage our growth, our expenses may increase more than expected, our revenue may not increase or may grow more slowly than expected and we may be unable to implement our business strategy. The quality of our services may also suffer, which could negatively affect our reputation and harm our ability to attract and retain clients.

We incur significant upfront costs in our client relationships, and if we are unable to maintain and grow these client relationships over time, we are likely to fail to recover these costs, which could have a material adverse effect on our business, financial condition and results of operations.

We derive most of our revenue from subscription access fees. Accordingly, our business model depends heavily on achieving economies of scale because our initial upfront investment is costly and the associated revenue is recognized on a ratable basis. We devote significant resources to establish relationships with our clients and implement our solution and related services. This is particularly so in the case of large enterprises that, to date, have comprised a substantial majority of our client base and revenue and often request or require specific features or functions unique to their particular business processes. Accordingly, our results of operations will depend in substantial part on our ability to deliver a successful experience for both clients and members and persuade our clients to maintain and grow their relationship with us over time. Additionally, as our business is growing significantly, our client acquisition costs could outpace our build‑up of recurring revenue, and we may be unable to reduce our total operating costs through economies of scale such that we are unable to achieve profitability. If we fail to achieve appropriate economies of scale or if we fail to manage or anticipate the evolution and in future periods, demand, of the subscription access fee model, our business, financial condition and results of operations could be materially adversely affected.

If our existing clients do not continue or renew their contracts with us, renew at lower fee levels or decline to purchase additional applications and services from us, it could have a material adverse effect on our business, financial condition and results of operations.

We expect to derive a significant portion of our revenue from renewal of existing client contracts and sales of additional applications and services to existing clients. As part of our growth strategy, for instance, we have recently focused on expanding our services amongst current clients. As a result, selling additional applications and services are critical to our future business, revenue growth and results of operations.

Factors that may affect our ability to sell additional applications and services include, but are not limited to, the following:

We enter into subscription access contracts with our clients. These contracts generally have stated initial terms of one year. Most of our clients have no obligation to renew their subscriptions for our solution after the initial term expires. In addition, our clients may negotiate terms less advantageous to us upon renewal, which may reduce our revenue from these clients. Our future results of operations also depend, in part, on our ability to expand into new clinical specialties and across care settings and use cases. If our clients fail to renew their contracts, renew their contracts upon less favorable terms or at lower fee levels or fail to purchase new products and services from us, our revenue may decline or our future revenue growth may be constrained.

In addition, after the initial contract year, a significant number of our client contracts allow clients to terminate such agreements for convenience at certain times, typically with one to three months advance notice. We typically incur the expenses associated with integrating a client’s data into our healthcare database and related training and support prior to recognizing meaningful revenue from such client. Subscription access revenue is not recognized until our products are implemented for launch, which is generally from one to three months from contract signing. If a client terminates its

contract early and revenue and cash flows expected from a client are not realized in the time period expected or not realized at all, our business, financial condition and results of operations could be adversely affected.

Our sales and implementation cycle can be long and unpredictable and requires considerable time and expense, which may cause our results of operations to fluctuate.

The sales cycle for our solution from initial contact with a potential lead to contract execution and implementation, varies widely by client, ranging from a number of days to approximately 24 months. Some of our clients undertake a significant and prolonged evaluation process, including to determine whether our services meet their unique healthcare needs, which frequently involves evaluation of not only our solution but also an evaluation of those of our competitors, which has in the past resulted in extended sales cycles. Our sales efforts involve educating our clients about the use, technical capabilities and potential benefits of our solution. Moreover, our large enterprise clients often begin to deploy our solution on a limited basis, but nevertheless demand extensive configuration, integration services and pricing concessions, which increase our upfront investment in the sales effort with no guarantee that these clients will deploy our solution widely enough across their organization to justify our substantial upfront investment. It is possible that in the future we may experience even longer sales cycles, more complex client needs, higher upfront sales costs and less predictability in completing some of our sales as we continue to expand our direct sales force, expand into new territories and market additional applications and services. If our sales cycle lengthens or our substantial upfront sales and implementation investments do not result in sufficient sales to justify our investments, it could have a material adverse effect on our business, financial condition and results of operations.

We operate in a competitive industry, and if we are not able to compete effectively, our business, financial condition and results of operations will be harmed.

While the telehealth market is in an early stage of development, it is competitive and we expect it to attract increased competition, which could make it difficult for us to succeed. We currently face competition in the telehealth industry for our solution from a range of companies, including specialized software and solution providers that offer similar solutions, often at substantially lower prices, and that are continuing to develop additional products and becoming more sophisticated and effective. These competitors include MDLive, Inc., American Well Corporation, and Grand Rounds, Inc. among other smaller industry participants. In addition, large, well‑financed health plans have in some cases developed their own telehealth or expert second-opinion tools and may provide these solutions to their customers at discounted prices. Competition from specialized software and solution providers, health plans and other parties will result in continued pricing pressures, which is likely to lead to price declines in certain product segments, which could negatively impact our sales, profitability and market share.

Some of our competitors may have greater name recognition, longer operating histories and significantly greater resources than we do. Further, our current or potential competitors may be acquired by third parties with greater available resources. 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 customer requirements and may have the ability to initiate or withstand substantial price competition. In addition, current and potential competitors have established, and may in the future establish, cooperative relationships with vendors of complementary products, technologies or services to increase the availability of their solutions in the marketplace. Accordingly, new competitors or alliances may emerge that have greater market share, a larger customer base, more widely adopted proprietary technologies, greater marketing expertise, greater financial resources and larger sales forces than we have, which could put us at a competitive disadvantage. Our competitors could also be better positioned to serve certain segments of the telehealth market, which could create additional price pressure. In light of these factors, even if our solution is more effective than those of our competitors, current or potential clients may accept competitive solutions in lieu of purchasing our solution. If we are unable to successfully compete in the telehealth market, our business, financial condition and results of operations could be materially adversely affected.

If we cannot implement our solution for clients or resolve any technical issues in a timely manner, we may lose clients and our reputation may be harmed.

Our clients utilize a variety of data formats, applications and infrastructure and our solution must support our clients’ data formats and integrate with complex enterprise applications and infrastructures. If our telehealth platform does not currently support a client’s required data format or appropriately integrate with a client’s applications and infrastructure, then we must configure our platform to do so, which increases our expenses. Additionally, we do not control our clients’ implementation schedules. As a result, if our clients do not allocate the internal resources necessary to meet their implementation responsibilities or if we face unanticipated implementation difficulties, the implementation may be delayed. If the client implementation process is not executed successfully or if execution is delayed, we could incur significant costs, clients could become dissatisfied and decide not to increase utilization of our solution or not to implement our solution beyond an initial period prior to their term commitment or, in some cases, revenue recognition could be delayed. In addition, competitors with more efficient operating models with lower implementation costs could jeopardize our client relationships.

Our clients and members depend on our support services to resolve any technical issues relating to our solution and services, and we may be unable to respond quickly enough to accommodate short‑term increases in member demand for support services, particularly as we increase the size of our client and membership bases. We also may be unable to modify the format of our support services to compete with changes in support services provided by competitors. It is difficult to predict member demand for technical support services, and if member demand increases significantly, we may be unable to provide satisfactory support services to our members. Further, if we are unable to address members’ needs in a timely fashion or further develop and enhance our solution, or if a client or member is not satisfied with the quality of work performed by us or with the technical support services rendered, then we could incur additional costs to address the situation or be required to issue credits or refunds for amounts related to unused services, and our profitability may be impaired and clients’ dissatisfaction with our solution could damage our ability to expand the number of applications and services purchased by such clients. These clients may not renew their contracts, seek to terminate their relationship with us or renew on less favorable terms. Moreover, negative publicity related to our client relationships, regardless of its accuracy, may further damage our business by affecting our reputation or ability to compete for new business with current and prospective clients. If any of these were to occur, our revenue may decline and our business, financial condition and results of operations could be adversely affected.

We depend on our senior management team, and the loss of one or more of our executive officers or key employees or an inability to attract and retain highly skilled employees could adversely affect our business.

Our success depends largely upon the continued services of our key executive officers. These executive officers are at‑will employees and therefore they may terminate employment with us at any time with no advance notice. We also rely on our leadership team in the areas of research and development, marketing, services and general and administrative functions. From time to time, there may be changes in our executive management team resulting from the hiring or departure of executives, which could disrupt our business. 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.

To continue to execute our growth strategy, we also must attract and retain highly skilled personnel. Competition is intense for qualified professionals. We may not be successful in continuing to attract and retain qualified personnel. We have from time to time in the past experienced, and we expect to continue to experience in the future, difficulty in hiring and retaining highly skilled personnel with appropriate qualifications. The pool of qualified personnel with experience working in the healthcare market is limited overall. In addition, many of the companies with which we compete for experienced personnel have greater resources than we have.

In addition, in making employment decisions, particularly in high‑technology industries, job candidates often consider the value of the stock options or other equity instruments they are to receive in connection with their employment. Volatility in the price of our stock may, therefore, adversely affect our ability to attract or retain highly skilled personnel. Further, the requirement to expense stock options and other equity instruments may discourage us from granting the size or type of stock option or equity awards that job candidates require to join our company. Failure to

attract new personnel or failure to retain and motivate our current personnel, could have a material adverse effect on our business, financial condition and results of operations.

We are dependent on our ability to recruit, retain and develop a very large and diverse workforce. We must transform our culture in order to successfully grow our business.

Our products and services and our operations require a large number of employees. A significant number of employees have joined us in recent years as a result of our acquisitions and our entry into new businesses. Our success is dependent on our ability to transform our culture, align our talent with our business needs, engage our employees and inspire our employees to be open to change, to innovate and to maintain member- and client-focus when delivering our services. Our business would be adversely affected if we fail to adequately plan for succession of our executives and senior management; or if we fail to effectively recruit, integrate, retain and develop key talent and/or align our talent with our business needs, in light of the current rapidly changing environment. While we have succession plans in place and we have employment arrangements with a limited number of key executives, these do not guarantee that the services of these or suitable successor executives will continue to be available to us. In addition, as we expand internationally, we face the challenge of recruiting, integrating, educating, managing, retaining and developing a more culturally diverse workforce.

If we fail to develop widespread brand awareness cost‑effectively, our business may suffer.

We believe that developing and maintaining widespread awareness of our brand in a cost‑effective manner is critical to achieving widespread adoption of our solution and attracting new clients. Our brand promotion activities may not generate client awareness or increase revenue, and even if they do, any increase in revenue may not offset the expenses we incur in building our brand. If we fail to successfully promote and maintain our brand, or incur substantial expenses in doing so, we may fail to attract or retain clients necessary to realize a sufficient return on our brand‑building efforts or to achieve the widespread brand awareness that is critical for broad client adoption of our solution.

Our marketing efforts depend significantly on our ability to receive positive references from our existing clients.

Our marketing efforts depend significantly on our ability to call upon our current clients to provide positive references to new, potential clients. Given our limited number of long‑term clients, the loss or dissatisfaction of any client could substantially harm our brand and reputation, inhibit widespread adoption of our solution and impair our ability to attract new clients and maintain existing clients. Any of these consequences could lower retention rate and have a material adverse effect on our business, financial condition and results of operations.

Any failure to protect our intellectual property rights could impair our ability to protect our technology and our brand.

Our success depends in part on our ability to enforce our intellectual property and other proprietary rights. We rely upon a combination of trademark and trade secret laws, as well as license and access agreements and other contractual provisions, to protect our intellectual property and other proprietary rights. In addition, we attempt to protect our intellectual property and proprietary information by requiring our employees, consultants and certain of our contractors to execute confidentiality and assignment of inventions agreements. These laws, procedures and restrictions provide only limited protection and any of our intellectual property rights may be challenged, invalidated, circumvented, infringed or misappropriated. To the extent that our intellectual property and other proprietary rights are not adequately protected, third parties may gain access to our proprietary information, develop and market solutions similar to ours or use trademarks similar to ours, each of which could materially harm our business. Unauthorized parties may also attempt to copy or obtain and use our technology to develop applications with the same functionality as our solution, and policing unauthorized use of our technology and intellectual property rights is difficult and may not be effective. The failure to adequately protect our intellectual property and other proprietary rights could have a material adverse effect on our business, financial condition and results of operations.

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 we may have difficulty integrating any such acquisitions successfully or realizing the anticipated benefits therefrom, any of which could have a material adverse effect on our business, financial condition and results of operations.

We may in the future seek to acquire or invest in businesses, applications and services or technologies that we believe could complement or expand our solution, enhance our technical capabilities or otherwise offer growth opportunities. 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.

In addition, we have limited experience in acquiring other businesses. If we acquire additional businesses, we may not be able to integrate the acquired personnel, operations and technologies successfully, or effectively manage the combined business following the acquisition. We also may not achieve the anticipated benefits from the acquired business due to a number of factors, including, but not limited to:

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 results of operations based on this impairment assessment process, which could adversely affect our results of operations.

Acquisitions could also result in dilutive issuances of equity securities or the incurrence of debt, which could adversely affect our results of operations. In addition, if an acquired business fails to meet our expectations, our business, financial condition and results of operations may suffer.

Taxing authorities may successfully assert that we should have collected or in the future should collect sales and use or similar taxes for telehealth services which could adversely affect our results of operations.

We do not collect sales and use and similar taxes in any states for telehealth services based on our belief that our services are not subject to such taxes in any state. Sales and use and similar tax laws and rates vary greatly from state to state. Additionally, we do not collect value added tax or similar taxes in certain foreign juridictions based on our belief that our services are not subject to such taxes. Certain states or foreign juridictions in which we do not collect such taxes

may assert that such taxes are applicable, which could result in tax assessments, penalties and interest with respect to past services, and we may be required to collect such taxes for services in the future. Such tax assessments, penalties and interest or future requirements may adversely affect our results of operations.

Economic uncertainties or downturns in the general economy or the industries in which our clients operate could disproportionately affect the demand for our solution and negatively impact our results of operations.

General worldwide economic conditions have experienced significant downturns during the last ten years, and market volatility and uncertainty remain widespread, making it potentially very difficult for our clients and us to accurately forecast and plan future business activities. During challenging economic times, our clients may have difficulty gaining timely access to sufficient credit or obtaining credit on reasonable terms, which could impair their ability to make timely payments to us and adversely affect our revenue. If that were to occur, our financial results could be harmed. Further, challenging economic conditions may impair the ability of our clients to pay for the applications and services they already have purchased from us and, as a result, our write‑offs of accounts receivable could increase. We cannot predict the timing, strength or duration of any economic slowdown or recovery. If the condition of the general economy or markets in which we operate worsens, our business could be harmed.

The estimates of market opportunity and forecasts of market growth included in this Form 10-K 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. The estimates and forecasts in this Form 10-K relating to the size and expected growth of the telehealth market may prove to be inaccurate. Even if the market in which we compete meets our size estimates and forecasted growth, our business could fail to grow at similar rates, if at all.

Natural or man‑made disasters and other similar events may significantly disrupt our business and negatively impact our business, financial condition and results of operations.

Our offices may be harmed or rendered inoperable by natural or man‑made disasters, including earthquakes, power outages, fires, floods, nuclear disasters and acts of terrorism or other criminal activities, which may render it difficult or impossible for us to operate our business for some period of time. For example, our headquarters are located in the greater New York City area, a region with a history of terrorist attacks and hurricanes. Any disruptions in our operations related to the repair or replacement of our offices, could negatively impact our business and results of operations and harm our reputation. Although we maintain an insurance policy covering damage to property we rent, such insurance may not be sufficient to compensate for losses that may occur. Any such losses or damages could have a material adverse effect on our business, financial condition and results of operations. In addition, our clients’ facilities may be harmed or rendered inoperable by such natural or man‑made disasters, which may cause disruptions, difficulties or material adverse effects on our business.

Our marketing efforts for the direct-to-consumer behavioral health portion of our business may not be successful or may become more expensive, either of which could increase our costs and adversely affect our business, financial condition, results of operations and cash flows.

Direct-to-consumer behavioral health represents a material portion of our overall business. We spend significant resources marketing this service. We rely on relationships for our direct-to-consumer behavioral health business with a wide variety of third parties, including Internet search providers such as Google, social networking platforms such as Facebook, Internet advertising networks, co-registration partners, retailers, distributors, television advertising agencies and direct marketers, to source new members and to promote or distribute our services and products. In addition, in connection with the launch of new services or products for our direct-to-consumer behavioral health business, we may spend a significant amount of resources on marketing. If our marketing activities are inefficient or unsuccessful, if important third-party relationships or marketing strategies, such as Internet search engine marketing and search engine optimization, become more expensive or unavailable, or are suspended, modified or terminated, for any reason, if there is an increase in the proportion of consumers visiting our websites or purchasing our services by way of marketing

channels with higher marketing costs as compared to channels that have lower or no associated marketing costs or if our marketing efforts do not result in our services being prominently ranked in Internet search listings, our business, financial condition, results of operations and cash flows could be materially and adversely impacted.

Provisions in our amended and restated certificate of incorporation and amended and restated bylaws and under Delaware law could make an acquisition of our company, which may be beneficial to our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management.

Provisions in our amended and restated certificate of incorporation and our amended and restated bylaws may discourage, delay or prevent a merger, acquisition or other change in control of our company that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares. These provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock, thereby depressing the market price of our common stock. In addition, because our board of directors is responsible for appointing the members of our management team, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors. Among other things, these provisions include those establishing:

Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the General Corporation Law of the State of Delaware, or the DGCL, which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner.

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for (1) any derivative action or proceeding brought on our behalf, (2) any action asserting a claim of breach of a fiduciary duty or other wrongdoing by any of our directors, officers, employees or agents to us or our stockholders, (3) any action asserting a claim arising pursuant to any provision of the DGCL or our amended and restated certificate of incorporation or amended and restated bylaws, (4) any action to interpret, apply, enforce or determine the validity of our amended and restated certificate of incorporation or amended and restated bylaws or (5) any action asserting a claim governed by the internal affairs doctrine. 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 our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and other employees. 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 have a material adverse effect our business, financial condition or results of operations.

Because we do not anticipate paying any cash dividends on our capital stock in the foreseeable future, capital appreciation will be your sole source of gain, if any.

We have never declared or paid cash dividends on our capital stock. We currently intend to retain all of our future earnings, if any, to finance the growth and development of our business. Any future debt agreements may preclude us from paying dividends. As a result, capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future.

We could be subject to securities class action litigation.

In the past, securities class action litigation has often been brought against a company following a decline in the market price of its securities. If we face such litigation, it could result in substantial costs and a diversion of management’s attention and resources, which could have a material adverse effect on our business, financial condition or results of operations.

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 on Form 10-K. 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.

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 common stock could decline.

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or 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 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 common stock could decline.

We have an unremediated material weakness in internal control over financial reporting. Our failure to establish and maintain effective internal control over financial reporting could result in our failure to meet our reporting obligations and cause investors to lose confidence in our reported financial information, which in turn could cause the trading price of our common stock to decline.

In connection with the preparation of our annual financial statements as of and for the year ended December 31,

2017, management identified a material weakness in our internal control. A material weakness is defined as a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

The material weakness pertains to the design and operating effectiveness of controls within the stock-based compensation process for awards with unique or different terms than our standard stock awards. This resulted in us not correctly recording certain stock-based compensation expense related to fourth quarter of 2017 awards of stock-based compensation. The material weakness had no impact on the Company’s financial position or cash flows.  

We are working to remediate the material weakness. In response to the material weakness, we have taken remedial action to strengthen our existing internal controls by designing a series of controls that address manual, infrequent or unique stock compensation awards. Additionally, our accounting staff responsible for preparing and reviewing stock based compensation expense will complete renewed training in the accounting of these types of awards as proscribed by current accounting standards. We expect to have these controls designed and implemented prior to March 31, 2018 and, to the extent there are appropriate transactions, the ability to test the operating effectiveness during the three months ending March 31, 2018. Although we plan to complete this remediation process as quickly as possible, we cannot at this time estimate how long it will take to fully remediate the material weakness. If our remedial measures are insufficient to address the material weakness, or if significant deficiencies or material weaknesses in our internal control over financial reporting are discovered or occur in the future, it may adversely affect the results of our management evaluations and annual auditor attestation reports regarding the effectiveness of our internal control over financial reporting required by Section 404 of the Sarbanes Oxley Act. In addition, if we are unable to successfully remediate the material weakness and if we are unable to produce accurate and timely financial statements or we are required to restate our financial results, our common stock price may be adversely affected and we may be unable to maintain compliance with the New York Stock Exchange listing requirements.

Item 1B.Unresolved Staff Comments

None.

Item 2.Properties

We believe that our company’s offices and other facilities are, in general, in good operating condition and adequate for our current operations and that additional leased space in appropriate locations can be obtained on acceptable terms if needed.

We lease approximately 21,000 square feet of office space in Purchase, New York for our corporate headquarters and certain of our operations under a lease for which the term expires in August 2023. In 2016, we executed a lease for approximately 19,000 square feet of office space in Phoenix, Arizona for one of our provider network operations centers. The lease has a seven-year initial term and provides for a five-year extension. In 2015 we executed a lease for approximately 73,000 square feet of office space in Lewisville, Texas for our provider network operations center and administrative purposes. The lease has a ten-year initial term and provides for two five-year extensions. As a result of our July 2017 Best Doctors acquisition, we lease approximately 50,000 square feet of office space in Quincy, Massachusetts primarily for another one of our provider network operations centers. The lease expires in August 2021. We also have a lease in Boston, Massachusetts for approximately 12,000 for administrative purposes that expires in 2025. For our foreign operations, we have a lease in Madrid, Spain for approximately 11,000 square feet that expires in October 2019 and Toronto, Canada for approximately 9,000 square feet that expires in December 2020. We also lease additional facilities elsewhere in the United States and other foreign locations.  We believe that our facilities are adequate to meet our needs for the immediate future, and that, should it be needed, suitable additional space will be available to accommodate any such expansion of our operations.

MANAGEMENT’S DISCUSSION AND ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

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

Overview

We are the largest and most trusted telehealth provider in the world. Recognized by MIT Technology Review as one of the “50 Smartest Companies”, we are forging a new healthcare experience with better convenience, outcomes and value. We provide virtual access to high quality care and expertise, with a portfolio of services and solutions covering 450 medical subspecialties from non-urgent, episodic needs like flu and upper respiratory infections, to chronic, complicated medical conditions like cancer and congestive heart failure. By combining the latest in data and analytics with an award-winning user experience and a highly flexible technology platform, we have delivered millions of medical visits to patients around the globe. Over 23.2 million unique Members now benefit from access to Teladoc 24 hours a day, seven days a week, 365 days a year. Our solution is delivered with a median response time of less than ten minutes from the time a Member requests a telehealth visit to the time they speak with a Teladoc physician. We completed approximately 1,463,000 telehealth visits, 952,000 telehealth visits and 576,000 telehealth visits for the year in 2017, 2016 and 2015, respectively. Paid membership increased by approximately 5.7 million members and 5.3 million members from December 31, 2016 through December 31, 2017 and from December 31, 2015 through December 31, 2016, respectively, including the impact from Best Doctors.

The Teladoc solution is transforming the access, cost and quality dynamics of healthcare delivery for all of our market participants. Our Members rely on Teladoc to remotely access affordable, on-demand healthcare whenever and wherever they choose. Employers, health plans and consumers, or our Clients, purchase our solution to reduce their healthcare spending while at the same time offering convenient, affordable, high-quality healthcare to their employees or beneficiaries. Our network of physicians and other healthcare professionals, or our Providers, have the ability to generate meaningful income and deliver their services more efficiently with no administrative burden. We believe the value proposition of our solution is evidenced by our overall Member satisfaction rate, which has exceeded 90% over the last nine years. We further believe any consumer, employer or health plan or practitioner interested in a better approach to healthcare is a potential Teladoc Member, Client or Provider.

In December 2017, we successfully closed on our Follow-On Offering in which the Company issued and sold 4,096,600 shares of common stock, including the exercise of an underwriter option to purchase additional shares, at an issuance price of $35.00 per share. We received net proceeds of $134.7 million after deducting underwriting discounts and commissions of $8.2 million as well as other offering expenses of $0.5 million. In January 2017, we successfully closed on our Follow-On Offering (“January 2017 Offering”) in which the Company issued and sold 7,887,500 shares of common stock, including the exercise of an underwriter option to purchase additional shares, at an issuance price of $16.75 per share. We received net proceeds of $123.9 million after deducting underwriting discounts and commissions of $7.6 million as well as other offering expenses of $0.6 million.

In July 2015, we successfully closed on our initial public offering, or IPO, in which the Company issued and sold 9,487,500 shares of common stock, including the exercise of an underwriter option to purchase additional shares, at an issuance price of $19.00 per share. We received net proceeds of $163.1 million after deducting underwriting discounts and commissions of $12.6 million as well as other offering expenses of $4.5 million.

We generate revenue from our Clients on a contractually recurring, per-Member-per-month and subscription access fee basis. In addition, we generate additional revenue on a per-telehealth general medical visit basis, through a visit fee. Certain of our Client contracts generate revenue for expert second opinions on a per case basis. Subscription access fees are paid by our Clients on behalf of their employees, dependents, policy holders, cardholders, beneficiaries or themselves, while general medical and other specialty visit fees are paid by either Clients or Members.

We generated revenue of $233.3 million, (including $47.0 million from Best Doctors), $123.2 million and $77.4 million for the years ended December 31, 2017, 2016 and 2015, respectively, representing 89% and 59% year-over-year growth from 2016 to 2017 and from 2015 to 2016. Excluding the impact from acquisitions our organic growth rate was

43%. We had net losses of $106.8 million, $74.2 million and $58.0 million for the years ended December 31, 2017, 2016 and 2015, respectively. For the year ended December 31, 2017, 85% and 15% of our revenue was derived from subscription access fees and visit fees, respectively. For both of the years ended December 31, 2016 and 2015, 82% and 18% of our revenue was derived from subscription access fees and visit fees, respectively.

Acquisition History

We have scaled and intend to continue to scale our platform through the pursuit of selective acquisitions. We have completed multiple acquisitions since our inception, which we believe have expanded our distribution capabilities and broadened our service offering.

On July 14, 2017, we completed the acquisition of Best Doctors Holdings, Inc., or Best Doctors, for aggregate consideration of $445.5 million, net of cash acquired of $13.7 million, comprised of $379.3 million of cash and 1,855,078 shares of our common stock valued at $66.2 million. Best Doctors is the world’s leading expert medical consultation company focused on improving health outcomes for the most complex, critical and costly medical issues.

On July1, 2016, we completed our acquisition of HY Holdings, Inc. d/b/a HealthiestYou Corporation, or HealthiestYou, for aggregate consideration of $145.3 million, net of cash acquired of $6.2 million, comprised of $37.0 million of cash and 6,955,796 shares of our common stock valued at $108.3 million. HealthiestYou is a leading telehealth consumer engagement technology platform for the small to mid-sized employer market.

On June 17, 2015, we completed our acquisition of Stat Health Services Inc., or StatDoc, for aggregate consideration of $30.1 million, comprised of $13.3 million of cash and 1,051,033 shares of our common stock valued at $16.8 million, net of cash acquired. StatDoc is a telehealth provider, focused on managed care, health system and self-insured clients.

In January 2015, we completed the acquisition of Compile, Inc. d/b/a BetterHelp, or BetterHelp, a provider of direct-to-consumer, behavioral health services, for $3.3 million net of cash acquired, a $1.0 million promissory note and additional annual payments to the sellers based on a percentage of the total net revenue generated by the BetterHelp business.

Key Factors Affecting Our Performance

Number of Members.  Our revenue growth rate and long-term profitability are affected by our ability to increase our number of Members because we derive a substantial portion of our revenue from subscription access fees via Client contracts that provide Members access to our professional Provider network in exchange for a contractual based monthly fee. Revenue is driven primarily by the number of Clients, the number of Members in a Client’s population, the number of services contracted for by a Client and the contractually negotiated prices of our services and the negotiated pricing that is specific to that particular Client. We believe that increasing our membership is an integral objective that will provide us with the ability to continually innovate our services and support initiatives that will enhance Member‘s experiences. Membership increased by approximately 5.7 million members from December 31, 2016 through December 31, 2017, including approximately 2.2 million members from the acquisition of Best Doctors and increased by approximately 5.3 million members from December 31, 2015 through December 31, 2016.

Number of Visits.  We also recognize revenue in connection with the completion of a general medical visit, expert second opinion and other specialty visits for the majority of our contracts. Accordingly, our visit revenue, or visit fees, generally increase as the number of visits increase. Visit fee revenue is driven primarily by the number of Clients, the number of Members in a Client’s population, Member utilization of our Provider network services and the contractually negotiated prices of our services. We believe that increasing our current Member utilization rate and further penetration into existing and sales to new health plan clients is a key objective in order for our Clients to realize tangible healthcare savings with our service. Visits increased by approximately 511,000 for the year ended December 31, 2017 compared to the same period in 2016.

Seasonality.  We typically experience the strongest increases in consecutive quarterly revenue during the

fourth and first quarters of each year, which coincides with traditional annual benefit enrollment seasons. In particular, as a result of many Clients’ introduction of new services at the very end of the current year, or the start of each year, the majority of our new Client contracts have an effective date of January 1. Additionally, as a result of national seasonal cold and flu trends, we experience our highest level of visit fees during the first and fourth quarters of each year when compared to other quarters of the year.  Conversely, the second quarter of the year has historically been the period of lowest utilization of our Provider network services relative to the other quarters of the year. See “Risk Factors—Risks Related to Our Business—Our quarterly results may fluctuate significantly, which could adversely impact the value of our common stock.” included elsewhere in this Annual Report on Form 10-K.

Components of Results of Operations

Revenue

We generate our revenue from our Clients who purchase access to our professional Provider network or our medical experts for their employees, dependents and other beneficiaries. Our Client contracts include a per-Member-per-month subscription access fee as well as contracts that generate additional revenue on a per-telehealth visit basis for general medical and other specialty visits and expert second opinion on a per case basis. Accordingly, we generate subscription access revenue from our subscription access fee and visit revenue from our general medical, expert second opinion and other specialty visit fees.

Subscription access revenue accounted for approximately 85%, 82% and 82% of our total revenue during the years ended December 31, 2017, 2016 and 2015, respectively. Subscription access revenue is driven primarily by the number of Clients, the number of Members in a Client’s population, the number of services contracted for by a Client and the contractually negotiated prices of our services. Visit fee revenue for general medical, expert second opinion and other specialty visits is driven primarily by the number of Clients, the number of Members in a Client’s population, Member utilization of our professional Provider network services and the contractually negotiated prices of our services.

We recognize subscription access fees and visit and second opinion access fees on a monthly basis when the following criteria are met: (i) there is an executed subscription agreement, (ii) the Member has access to the service, (iii) the services are performed, (iv) collection of the fees is reasonably assured and (v) the amount of fees to be paid by the Client and Member is fixed and determinable. Our agreements generally have a term of one year. The majority of Clients renew their contracts with us following their first year of services.

Warranties and Indemnification

Our arrangements generally include certain provisions for indemnifying Clients against liabilities if there is a breach of a Client’s data or if our service infringes a third party’s intellectual property rights. To date, we have not incurred any material costs as a result of such indemnifications.

We have also agreed to indemnify our directors and executive officers for costs associated with any fees, expenses, judgments, fines and settlement amounts incurred by any of these persons in any action or proceeding to which any of those persons is, or is threatened to be, made a party by reason of the person’s service as a director or officer, including any action by us, arising out of that person’s services as our director or officer or that person’s services provided to any other company or enterprise at our request. We maintain director and officer liability insurance coverage that would generally enable us to recover a portion of any future amounts paid. We may also be subject to indemnification obligations by law with respect to the actions of our employees under certain circumstances and in certain jurisdictions.

Concentrations of Risk and Significant Clients

Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investment and accounts receivable. Although we deposit our cash with multiple financial institutions in U.S. and in foreign countries, our deposits, at times, may exceed federally insured limits. Our short-term

investment are comprised of a portfolio of diverse high credit rating instruments with maturity durations of one year or less.

Revenue from Clients located in the United States for the year ended December 31, 2017 was $214.5 million. Revenue from Clients located outside the United States for the year ended December 31, 2017 was $18.8 million.

During the year ended December 31, 2016 and 2015, substantially all of our revenue was generated by Clients located in the United States.

No Client represented over 10% of accounts receivable at December 31, 2017 and 2015 or revenue for the years ended December 31, 2017, 2016 and 2015. One Client represented 11% of accounts receivable at December 31, 2016.

Cost of Revenue

Cost of revenue primarily consists of fees paid to our Providers and medical experts, costs incurred in connection with our Provider network operations, which include employee-related expenses (including salaries and benefits), costs related to our Provider network operations center activities, medical records, magnetic resonance imaging, medical lab tests, translation, postage and medical malpractice insurance. Cost of revenue is driven primarily by the number of general medical visits, expert second opinions and other specialty visits completed in each period. Many of the elements of the 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 currently expect to continue to enhance our Provider network operations center as well as our sales and technology capabilities to support business growth, we believe our increased investment in automation and integration capabilities and economies of scale in our Provider network operations center operating model, will position us to grow our revenue at a greater rate than our cost of revenue.

Gross Profit

Our gross profit is our total revenue minus our total cost of revenue, and we also express our gross profit as a percentage of our total revenue. Our gross profit has been and will continue to be affected by a number of factors, including the fees we charge our Clients, the number of visits and cases we complete the costs paid to Providers and medical experts as well as the costs of our Provider network operations center. We expect our annual gross profit to remain relatively steady over the near term, although our quarterly gross profit is expected to fluctuate from period to period depending on the interplay of these aforementioned factors.

Advertising and Marketing Expenses

Advertising and marketing expenses consist primarily of costs of digital advertisements, personnel and related expenses for our marketing staff and communications materials that are produced for member acquisition and to generate greater awareness and utilization among our Clients and Members. Marketing costs also include third-party independent research, trade shows and brand messages, public relations costs and stock-based compensation for our advertising and marketing employees. Our advertising and marketing expenses exclude certain allocations of occupancy expense as well as depreciation and amortization.

We expect our advertising and marketing expenses to increase for the foreseeable future as we continue to increase the size of our digital advertising and marketing operations including member acquisition and engagement activities and expand into new products and markets. Our advertising and marketing expenses will fluctuate as a percentage of our total revenue from period to period due to the seasonality of our total revenue and the timing and extent of our advertising campaigns and marketing expenses. We will continue to invest in advertising and marketing by promoting our brands through a variety of marketing and public relations activities.

Sales Expenses

Sales expenses consist primarily of employee-related expenses, including salaries, benefits, commissions, employment taxes, travel and stock-based compensation costs for our employees engaged in sales, account management

and sales support in addition to commissions paid to external brokers. Our sales expenses exclude certain allocations of occupancy expense as well as depreciation and amortization. We expect our sales expenses to increase in the short-to-medium-term as we strategically invest to expand our business and to capture an increasing amount of our market opportunity.

Technology and Development Expenses

Technology and development expenses include personnel and related expenses for software engineering, information technology infrastructure, security and compliance and product development. Technology and development expenses also include outsourced software engineering services, the costs of operating our on-demand technology infrastructure, licensed applications and stock-based compensation for our technology and development employees. Our technology and development expenses exclude certain allocations of occupancy expense as well as depreciation and amortization.

We expect our technology and development expenses to increase for the foreseeable future as we continue to invest in the development of our technology platform. Our technology and development expenses may fluctuate as a percentage of our total revenue from period to period due to the seasonality of our total revenue and the timing and extent of our technology and development expenses. Historically, the majority of our technology and development costs have been expensed.

Legal and Regulatory Expenses

Legal and regulatory expenses include professional fees incurred. Our legal and regulatory expenses exclude certain allocations of personnel and related expenses, occupancy expense as well as depreciation and amortization.

Acquisition and Integration Related Costs

Acquisition and integration related costs include investment banking, financing, legal, accounting, consultancy, integration and certain non-recurring transaction costs related to mergers and acquisitions.

General and Administrative Expenses

General and administrative expenses include personnel and related expenses of, and professional fees incurred by our executive, finance, product development, business development, operations and human resources departments. They also include stock-based compensation costs related to our board of directors and our employess and most of the facilities costs including utilities and facilities maintenance. Our general and administrative expenses exclude any allocation of depreciation and amortization.

We expect our general and administrative expenses to increase for the foreseeable future as we continue to grow our business. However, we expect our general and administrative expenses to decrease as a percentage of our total revenue over the next several years. Our general and administrative expenses may fluctuate as a percentage of our total revenue from period to period due to the seasonality of our total revenue and the timing and extent of our general and administrative expenses.

Depreciation and Amortization

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

Amortization of Warrants and Loss on Extinguishment of Debt

Amortization of warrants and loss on extinguishment of debt consists of the recognition of the fair value of warrants in connection with the July 2016 Mezzanine Term Loan, the write-off of origination and termination financing fees and related deferred financing costs in connection with SVB indebtedness and 2017 New Term Loan extinguished in connection with our 2016, July 2017 refinancings and December 2017 offering.

Interest Expense, Net

Interest expense, net consists of interest costs associated with our bank, other debt and amortization of debt issuance costs and costs associated with the Convertible Senior Notes and the New Term Loan, net of interest earned on short-term marketable securities.

Foreign Currency

The functional currency for each of our foreign subsidiaries is the local currency. All assets and liabilities denominated in a foreign currency are translated into U.S. dollars at the exchange rate on the balance sheet date. Revenues and expenses are translated at the weighted average exchange rate during the period. Cumulative translation gains or losses are included in stockholders’ equity as a component of accumulated other comprehensive income (loss). We have not utilized hedging strategies with respect to such foreign exchange exposure.

Income Tax Provision

We follow the provisions of the accounting guidance on accounting for income taxes which requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is provided to reduce the deferred tax asset to a level which, more likely than not, will be realized. We have recorded deferred tax liabilities arising principally from deferred tax liabilities associated with indefinitely lived intangible assets in the U.S. and from deferred tax liabilities in foreign jurisdictions. We have provided a full valuation allowance for our U.S. deferred tax assets at December 31, 2017 and 2016, as it is more likely than not that these assets will not be realized in the future.

H.R. 1, new tax legislation, commonly referred to as the Tax Cuts and Jobs Act, was enacted on December 22, 2017. The Tax Act includes significant changes to the Internal Revenue Code of 1986, as amended, including amendments which significantly change the taxation of business entities. ASC 740, Accounting for Income Taxes, requires companies to recognize the effect of tax law changes in the period of enactment. Amounts recorded in the year ended December 31, 2017 principally relate to the permanent reduction in the U.S. corporate income tax rate from 35 percent to 21 percent, effective January 1, 2018, which resulted in the remeasurement of the net deferred tax liabilities associated with indefinitely lived intangible assets. Absent this deferred tax liability, the Company is in a net deferred tax asset position that is offset by a full valuation allowance.

Consolidated Results of Operations

The following table sets forth our consolidated statement of operations data for the years ended December 31, 2017, 2016 and 2015 and the dollar and percentage change between the respective periods (dollars in thousands):
