Business PART I If you’ve purchased apparel from a major retailer like Macy’s or Zara, run a race like the New York City Marathon, enjoyed a drink from a Coca-Cola Freestyle soda fountain, hit a ball at Topgolf or checked bags at airports worldwide like Las Vegas McCarran then you’ve probably interacted with the Impinj Platform. Our platform enables wireless connectivity to billions of everyday items such as apparel, race bibs, golf balls and luggage and delivers each item’s unique identity, location and authenticity to business and consumer applications. Overview Our vision is digital life for everyday items. Our mission is to connect these everyday items to business and consumer applications. We believe that by expanding the reach of the Internet to items such as retail apparel, medical supplies, pharmaceuticals, airline luggage, automotive parts, food – nearly everything – we can improve peoples’ lives. Our platform wirelessly connects these everyday items and delivers each item’s unique identity, location and authenticity – which we refer to as Item Intelligence – to applications like inventory management, patient safety, asset tracking and item authentication. Internet-of-Things We live in a connected world. Smartphones, tablets and other devices share ever-more information over ever-more interconnected radio links, transforming our lives and unlocking unprecedented efficiencies. Advancements in wireless technology, cloud computing, data analytics, search and storage have paved the way for this connected era. However, the items connected today represent only a tiny subset of the items in the physical world. Apparel, shoes, jewelry, pharmaceuticals, medical supplies, documents, automotive parts, sporting items and food are among the more than a trillion such everyday items which are now connectable to the digital world yet remain mostly unconnected. Our Solution We sell a platform that connects everyday items using RAIN, a radio-frequency identification, or RFID, technology we pioneered. We spearheaded development of the RAIN radio standard, lobbied governments to allocate frequency spectrum and cofounded the RAIN Industry Alliance along with Google, Intel and Smartrac . Today, our industry uses the RAIN radio standard nearly exclusively, has access to freely available spectrum in 78 countries representing roughly 96.5% of the world’s GDP and the RAIN Alliance has more than 125 member companies worldwide. Impinj Platform The Impinj platform comprises a software layer, a connectivity layer and an endpoint layer that together connect items to applications. Within each layer we sell one or more product families. Software Our software layer today comprises two products, ItemSense and ItemEncode. ItemSense is the operating system for our platform. It extracts Item Intelligence from the connectivity and endpoint layers and delivers that Item Intelligence to business and consumer applications. It also centralizes reader and gateway configuration, management and control through a management application program interface, or API. It is modular, scalable and secure and can operate on-premises, in hybrid-cloud or in cloud-based environments. ItemSense can connect, manage and process data from hundreds of readers or gateways. We have recently begun initial deployments of ItemSense. 5 ItemEncode encodes item information into endpoint integrated circuits, or ICs. A single ItemEncode-ena bled system can reliably encode many tens-of- thousands of endpoint ICs per hour. Connectivity Our connectivity layer comprises a family of readers, gateways and reader ICs that wirelessly identify, locate, authenticate and engage endpoints via RAIN. These connectivity products wirelessly provide power to, and communicate bidirectionally with, endpoint ICs, identifying and locating up to 1,000 items per second. Readers and Gateways. Our readers read, write, authenticate or otherwise engage endpoint ICs. Our gateways integrate stationary readers with scanning antennas to locate and track endpoints. Our readers and gateways are easy to deploy and use, can be powered via power-over-Ethernet and are certified for operation in more than 40 countries. Our customers have deployed our readers and gateways in applications ranging from retail inventory-taking to automated fuel filling to shipping-container tracking to airport luggage handling. Our stationary reader product family, branded Speedway, comprises high-performance finished products. We sell our Speedway readers through an established channel of distributors, system integrators, or SIs, value-added resellers, or VARs, and solution providers. Our readers sell for hundreds of dollars. Our gateway product family integrates our Speedway readers with beamforming antennas to electrically steer a radio beam like a searchlight. Their always- on, autonomous operation delivers timely Item Intelligence without ongoing labor costs. Our portal gateways, branded xPortal and xSpan, scan doorways or hallways such as front-to-back store transitions, entryways and exits. Our array gateway, branded xArray, scans up to 1,500 square feet of floor space such as in a store, manufacturing facility or hospital room. Our gateways sell for thousands of dollars. Reader ICs. Our reader IC product family, branded Indy, comprises a suite of ICs and systems-in-package, or SIPs, that combine our reader ICs with peripheral circuitry in an easy-to-use format. Our reader ICs and SIPs read, write, authenticate or otherwise engage endpoint ICs; we sell them to original equipment manufacturing, or OEM, and original design manufacturing, or ODM, partners that use them in a variety of products such as mobile or handheld readers, fixed readers, gateways, and RAIN-enabled appliances. We offer easy-to-use APIs, development environments, sample code, drivers and libraries. We sell our reader ICs and SIPs for tens of dollars. Endpoints Our endpoint IC product family, branded Monza, comprises a family of miniature radios-on-a-chip that attach-to and uniquely identify their host items. They may include standardized features such as user data storage, authentication, security, loss prevention and consumer privacy, and also may include value-added custom features, all accessible by our platform. Our endpoint ICs power themselves from a reader’s radio waves so don’t need a battery, can wirelessly connect almost any item, are readable to 30 feet without line-of-sight yet sell for pennies. Our OEM partners attach each endpoint IC to a thin printed antenna on a paper or Mylar backing, then typically cover the composite inlay with a paper face to form a tag. End customers attach the tag to an item in markets including retail, healthcare, automotive, industrial and manufacturing, consumer experience, food, datacenter, travel and banking. We refer to a tag and its host item as an endpoint. Endpoint ICs differ from traditional silicon ICs in that most endpoint ICs are disposable. For example, when consumers purchase retail items they discard the price tags containing the endpoint ICs. We believe endpoint ICs are the first market for consumable silicon and are a recurring revenue source for us. We have shipped more than 18 billion endpoint ICs to date, including approximately 6.0 billion and 3.5 billion in the twelve months ended December 31, 2016 and 2015, respectively. 6 Opportunity Our opportunity is to connect everyday items to the digital world. That digital world has the capability today to analyze and use data from everyday items, but the infrastructure and processes required to capture and deliver item-level data has historically been nonexistent or labor-intensive, expensive, and ineffective. For example, retailers have not historically had an automated way to track in-store inventory so they have relied on infrequent and labor-intensive manual counts. Similarly, hospitals have not historically had an automated, timely way to track biospecimens so they have resorted to labor-intensive barcode scanning. In these and numerous other examples, a lack of real-time information about item identity and location has increased inventory carrying costs, reduced operating efficiencies, and consumed labor and time. Our platform enables capturing and delivering item-level data to the digital world. It is part of a large and growing worldwide infrastructure that produces, encodes and applies tags to items, and connects and extracts timely business value from those tagged items. Two of our many market opportunities, retail and healthcare, demonstrate how our addressable market for item connectivity is large and growing. Frost & Sullivan, a market research firm, forecasts the retail opportunity will grow at a 39% CAGR between 2014 and 2020, reaching $5.4 billion by 2020. Transparency Market Research, another market research firm, forecasts the healthcare opportunity will grow at a 14% CAGR between 2014 and 2020, reaching $5.3 billion by 2020. We have additional opportunities in automotive, industrial and manufacturing, consumer experience, government, food, datacenter, travel and banking. RAIN market adoption has historically been slower than anticipated or forecasted by us and industry sources. For additional information related to RAIN market adoption, please see the section of this report captioned “Risk Factors.” Industry Use Cases We believe we are the only company selling a platform spanning endpoints, connectivity and operating-system software . The following use cases are representative of actual RAIN deployments we serve. Retail Retailers, both traditional “brick-and-mortar” and online, are consuming billions of tags each year to obtain real-time Item Intelligence about products they manufacture, transport and sell. By using our platform retailers can obtain these benefits: • • • • • Improve Inventory Visibility . U.S apparel retailers historically inferred store inventory using manual counts, store-receipt data and point-of-sale data, typically resulting in 65% visibility based on industry sources. From measured data, RAIN offers apparel retailers better than 95% inventory visibility. Reduce Out-of-Stocks and Markdowns . Item Intelligence helps retailers increase revenue by enabling them to stock shelves accurately, reducing inventory costs, out-of-stocks and overstock markdowns. Enable Omnichannel Fulfillment . Item Intelligence allows retailers to optimize logistics and increase selling opportunities using omnichannel fulfillment, offering online shoppers next-day, direct-from- store delivery or in-store pickup. Enhance Shopping Experiences . Item Intelligence enables retailers to engage shoppers with interactive fitting rooms and product displays. It can also provide retailers real-time data on shopper preferences. Identify and Prevent Loss . Item Intelligence can help retailers deter theft and uniquely identify stolen items for replenishment. 7 Healthcare The healthcare industry is increasingly focusing on patient quality-of-care, increasing pressure on hospitals and healthcare providers to obtain real-time Item Intelligence about assets, inventory, staff and patients. By tagging items and using our platform they can obtain these benefits: • • • • • Asset Management . By tagging hospital assets and installing RAIN readers or gateways at key locations throughout a facility, items can be easily monitored. Hospital staff gain real-time knowledge of each asset’s location, as well as status information about whether the item is in-use or available. Operating-Room Supply Tracking . By tracking medical supplies and items, hospitals can improve point-of-use visibility and data integration into billing and enterprise resource planning, or ERP, systems. Medical Cabinets. RAIN enabled cabinets, refrigerators, and freezers automate management of medical equipment and supply inventory and send automatic alerts on temperature or expiration date issues. Medical-Kit Replenishment . Item Intelligence allows hospitals and surgery centers to verify the contents of medical kits quickly and reliably, increasing operating-room charge capture and reducing staff time locating missing kit contents. Pharmaceutical Inventory Management : Our platform enables pharmaceutical companies to track tagged items from point-of-manufacturing to a pharmacy, reducing stocking costs and improving product availability. Other Industries Other industries are also deriving business value from RAIN and Item Intelligence. A few examples of deployments that use part or all of the Impinj Platform include: • • • • • • • Automotive . Fueling stations use vehicle windshield tags to enable automatic, cashless fueling. Industrial and Manufacturing . Car and aircraft manufacturers tag and track components to ensure proper assembly, reduce labor costs and improve operations. Consumer Experience . Foot races track runners via endpoint ICs in race bibs; golf venues score participants’ shots via endpoint ICs inside golf balls. Food . Coca-Cola uses our endpoint and reader ICs for syrup tracking and replenishment in its Freestyle soda fountains. A fast food chain uses our endpoint ICs and gateways to enable direct-to-table food service. Datacenter . Datacenters use our platform for asset tracking. Electronics manufacturers embed our endpoint ICs into electronic devices for processor-secured storage. Travel . Some airports, as well as a major U.S. airline, use RAIN-enabled luggage tags. Driver licenses in some states in the United States include our endpoint ICs to speed border crossings. Banking . Banks use our endpoint ICs for their money bundles and information technology assets. Competitive Advantages We lead the market in connecting and delivering Item Intelligence for everyday items. We believe we can maintain and extend our leadership position as the market grows by leveraging our competitive strengths, including: • • Comprehensive Platform . End users who deploy the Impinj Platform gain performance, reliability and ease-of-use we believe is unequaled by “mix-and-match” systems cobbled-together from competitors’ components. We believe our success with these end users will drive broader adoption of our platform. Market Leadership . Our platform is integrated, easy to deploy and use, versatile and applicable to many use cases, and delivers unmatched performance. We believe we are the only company with an integrated RAIN platform, and we have leading market share in endpoint ICs, reader ICs and stationary readers. 8 • • • Broad Partner Ecosystem . Our worldwide partner ecosystem comprising more than 500 distributors, system integrators, value-added resellers, or VARs, and software solution partners as of December 31, 2016 gives us market re ach, penetration and scalability we believe few, if any, of our competitors enjoy. Technology Leadership . Our chief executive officer is a recognized industry thought leader. He is a director of the RAIN Industry Alliance and was editor for the RAIN radio standard. Our intense focus on RAIN and Item Intelligence has enabled us to be first-to-market with innovative, high-quality products. As of December 31, 2016, our intellectual property portfolio includes 204 issued and allowed U.S. patents and 36 pending U.S. patent applications and three pending international patent applications. Trusted Brand . We believe our industry leadership, name recognition and reputation for innovative, high-performing and quality products have significantly contributed to our leading market position. We believe our brand is unmatched in the industry, helping us sell products and maintain our market leadership. Growth Strategies To further our mission of connecting and delivering Item Intelligence for everyday items, we plan to focus on the following strategic areas: • • • • • Continue Investing in Our Platform . Since 2003, we have invested more than $182 million developing our platform. We plan to continue investing in platform functionality, software/hardware linkages, broadening our software capabilities, enhancing platform features such as item authentication and loss prevention and reducing costs. We also plan to enhance our gateway functionalities to help drive gateways as the preferred connectivity devices for retail, healthcare and other industries. Since 2003, investment in our platform comprised: $172 million in research and development expense, $9 million in costs for development agreements and $1 million in capitalized internal-use software. Drive End-User Adoption . We plan to deepen our platform integration with software partners and to grow our sales, support and product- development teams. These investments will allow us to expand our engagements with end users in retail, healthcare and other industries and accelerate their adoption of the Impinj Platform. We also intend to broaden our partner ecosystem and expand our solutions focus and offerings. To meet the growing demand for our products, we are expanding inventory and reducing product lead times. Cross-Sell and Up-Sell Our Platform within our Installed Footprint . We believe the majority of RAIN deployments today use one or more of our products, positioning us for future platform cross-sell and up-sell opportunities. For example, retailers that deploy our gateways see improved inventory accuracy when using our endpoint ICs, positioning us to up-sell our platform into these retail accounts. Expand within our Existing Customer Base . We will seek additional revenue from existing end users of our platform by expanding their deployment scope and adding new use cases. For example, retailers typically start deploying RAIN by tagging apparel. We see opportunities to expand their tagging to housewares, appliances, cosmetics and eventually all items in a store. These same retailers typically choose inventory visibility as their first use case. We see opportunities to extend their use cases for already-tagged items to omnichannel fulfillment, loss prevention, enhanced retail analytics and more. Enable Ubiquitous Reading . We plan to invest in next-generation reader ICs to improve functionality, reduce costs, and make Impinj-based readers ubiquitous in industrial and consumer devices and facilities infrastructure. Sales and Marketing Our go-to-market model prioritizes brand development, end-user awareness, lead generation and sales enablement. Our communications use web, electronic and channel programs complemented by press initiatives and industry-analyst relationships. Our solutions-marketing, business-development and solutions-architecture teams work with our partner independent software vendors, or ISVs, to enable joint solutions and joint go-to-market selling. 9 We deliver products and solutions that are easy for our partner ecosystem to sell and deploy. We engender preference for our platfor m in all sales engagements, encouraging end users to deploy our multiple products to gain full benefit from our platform. Our business development, product marketing, technical and systems engineers all actively engage partners and end customers. Our sales force leverages a global partner ecosystem of distributors, SIs, VARs and ISV partners. Each regional sales team sells all of our products. We organize our sales team primarily by geography: (1) Americas, (2) Asia Pacific and (3) Europe, Middle East and Africa. We also have a small number of worldwide sales executives with expertise in endpoint and reader ICs to support the geographic sales teams. Because our operating-system software is still relatively new to the market, the revenue we derive from software is small, so we currently derive most of our revenue from connectivity product and endpoint IC sales. We sell our products as follows: • • • • Software through distributors, VARs, system integrators and other software-solution partners. Readers and gateways primarily to VARs and system integrators through distributors. Reader ICs primarily through distribution to reader OEMs and ODMs. Endpoint ICs directly to inlay and tag OEMs and ODMs. We typically negotiate pricing, volumes and deliveries with these OEMs an d ODMs yearly, with new pricing effective during the first quarter of the calendar year.

Ltd., or Shang Yang, and Blue Star, Inc., or Blue Star, as of the dates presented: Revenue: Smartrac Avery Arizon Shang Yang Blue Star 2016 YEAR ENDED DECEMBER 31, 2015 2014 16% 14 11 10 9 60% 14% 10 9 15 16 64% 11% 11 14 6 12 54% We engage directly with end users in collaboration with partners across our ecosystem, usually fulfilling sales through those same partners. In some instances, these end-customer engagements leverage go-to-market relationships with companies who do not sell our products but whose product offerings complement ours. Many of our partners sell multiple of our products or our entire platform. Manufacturing We outsource all our product manufacturing to third-party manufacturers that build our products to our design specifications. This capital-efficient operating model scales efficiently with volume, allowing us to focus our resources on accelerating development of new products and solutions. Taiwan Semiconductor Manufacturing Company Limited, or TSMC, fabricates our endpoint ICs in Asia and the United States and has been our sole endpoint IC supplier since 2003. We order endpoint IC wafers on a purchase-order basis and do not have a long-term agreement with TSMC. We test the wafers at our U.S. headquarters and in Asia. We use multiple subcontractors to post-process the wafers. Our primary subcontractor for our endpoint ICs is Stars Microelectronics (Thailand) Public Company Limited, or Stars. We generally engage all our endpoint IC subcontractors on a purchase-order basis. 10 TowerJazz Ltd. fabricates our reader ICs in the United States and has been our sole reader IC supplier since 2008. We order reader IC wafers on a purchase-order basis and do not have a long-term agreement with TowerJaz z. We use subcontractors on a purchase-order basis to package the ICs and test the packaged parts. Plexus Corp. manufactures our readers in Asia and has been our sole supplier since 2005. Plexus and Western Corporation in the United States have manufactured our gateways since 2013 and 2010, respectively. We order readers and gateways pursuant to nonexclusive purchase agreements that renew automatically each year, subject to each party’s right to terminate upon 180 days’ notice. We engage subcontractors on a purchase-order basis to assemble and test printed circuit boards, to build our reader and gateway enclosures and test our readers and gateways. Research and Development We built our company around technology leadership and innovation. We have committed, and plan to continue committing, significant resources to technology and product innovation and development. We achieved our market leadership by innovating, delivering and continuously improving product performance, features, quality and reliability while also reducing costs. In most situations, we strive to lead the market with new innovations, but we sometimes adopt a “fast follower” approach depending on the market situation. As one example, endpoint IC performance typically improves when we migrate the semiconductor processing to more advance process nodes. We execute these node migrations when the development costs, performance improvements, competitive situation and product cost reductions justify the migration. But external factors, such as the ability of our OEM and ODM partners to process larger wafers with smaller ICs can cause us to delay, or even allow our competition to temporarily lead, while we develop competitive products that we introduce when our OEM and ODM partners are ready. We have assembled a team of skilled engineers and currently perform all research and most of our product development internally. As of December 31, 2016, we had 107 employees in research and development, of which eight hold a Ph.D. and 34 hold a master’s degree. Research and development expenses for 2016, 2015 and 2014 were $25.2 million, $17.6 million and $14.3 million, respectively. We regularly review our technology, products, developments and product opportunities and reallocate our spending and resources accordingly. Intellectual Property We protect our technologies by filing patent applications, retaining trade secrets and defending and enforcing our intellectual-property rights where appropriate. To date, our intellectual property portfolio includes 204 issued and allowed U.S. patents, 36 pending U.S. patent applications and three pending international patent applications. The first of our 175 issued utility patents expire in 2024 and the first of our 26 issued design patents expire in 2021. To protect confidential information not otherwise subject to patent protection, we rely on trade secret law and enter into confidentiality agreements with our employees, customers, suppliers and partners. Because most RAIN products are used in, or imported into, the United States, we believe U.S. patents hold the most value for our business. Consequently, we have filed primarily U.S. patent applications. We have a small number of pending foreign patent applications but none have yet allowed or issued. Because our portfolio currently contains only U.S. patents, we have limited ability to assert our intellectual-property rights outside the United States. Although our patents and trade secrets constitute valuable assets, we do not view any one of them as material. Instead, we believe the totality of our patent and trade-secret portfolio creates an advantage for our business. 11 We have entered into licensing, broad-scope cross-licensing and other agreements authorizing us to use or to operate within the scope of patents and intellectual property owned by third parties. For example, we have licenses to third-party intellectual property that we use in our products. As another example, by participating in developing GS1 EPCglobal protocols, such as the RAIN radio protocol, we agreed to lice nse those of our patents necessarily infringed by the practice of these protocols on a royalty-free basis to other GS1 EPCglobal members, subject to reciprocal royalty-free rights from those members. We believe 14 of our patents and pending applications ar e necessary to practice the RAIN radio protocol. By participating in developing ISO standards, we have agreed to grant to all users worldwide a license to those of our patents necessarily infringed by the practice of several ISO standards, including non-RA IN standards, on reasonable and nondiscriminatory terms, subject to reciprocity. We own a number of trademarks, develop names for our new products and secure trademark protection for them, including domain name registration, in relevant jurisdictions. Alliances and Standardization We, along with Google, Intel and Smartrac, cofounded the RAIN Industry Alliance in 2014. Our chief executive officer is presently an Alliance Director and was previously the Alliance Chairman. The Alliance is a global organization promoting the universal adoption of RAIN technology and solutions with more than 125 members as of the date of this report. The name “RAIN” connotes ubiquity and a close link to cloud data. We, our customers, partners and competitors developed the RAIN radio protocol, UHF Gen2 (standardized as ISO/IEC 18000-63) in 2004, with us as the editor. Our community delivered a backwards-compatible update in 2013, again with us as the editor. Our industry uses Gen2 nearly exclusively. By participating in GS1 EPCglobal, which produced Gen2, and ISO, which ratified 18000-63, as well as in other standards bodies, we agreed to license certain patents as described in the section captioned “Intellectual Property.” Government Regulations Government regulations require us to certify our readers and gateways in jurisdictions where they operate. For example, we certify our readers and gateways to Federal Communications Commission regulations to operate in the United States and its territories. Currently, our Speedway readers are certified for operation in more than 40 countries worldwide including the United States, Canada, Mexico, China, Japan, South Korea and all of the European Union. Our gateway products have the same or fewer certifications, depending on the recency of the product introduction; we plan to eventually certify them in all countries with compelling market opportunities. Competition We believe we are the only company in our industry with a platform spanning software, connectivity and endpoints. Our competitors compete with us with respect to some, but not all, of our business. Our principal competition in our platform layers include: • • • • Software. Zebra Technologies Corporation, or Zebra, and Mojix. Readers and Gateways. Alien Technology Corporation, or Alien, and Zebra Technologies, Inc., both of which also purchase our reader ICs. Reader ICs. STMicroelectronics and Phychips Inc. Endpoint ICs. NXP B.V., or NXP, and Alien. In October 2016, Qualcomm Incorporated, or Qualcomm, announced it entered into a definitive agreement to acquire NXP. Qualcomm could use this acquisition as an entry point into the endpoint IC market. 12 The market for our platform and products is relatively new and highly competitive. We believe competition will increase as the market grows and RAIN technology continues to advance. New entrants could enter our market at any time, creating additional competition in the future. The competitive factors that impact our platform and product sales include: • • • • • portfolio, performance, features, lead times, reliability and price; support, ease of use and availability of reference designs; development tools and API availability (except in the endpoint IC market); integration and certification with end-user applications; and company reputation. Although we believe we compete favorably on the above factors, our future competitiveness will depend upon our ability to design, develop and deliver compelling solutions. We occasionally experience competitive pressures due to prevailing exchange rates as our product pricing is denominated in U.S. dollars. In addition, our competitive position depends on our ability to continue to attract and retain talent while protecting our intellectual property. For additional information on the risks associated with our business, see “Risk Factors.” Employees and Culture As of December 31, 2016, we had 245 employees, with 224 of those in the United States, 9 in the Asia Pacific region, 11 in Europe and one in Latin America. None of our employees are represented by a labor union, and we believe our employee relations are excellent. We use four words to capture the essence of our corporate culture—innovation, action, commitment and team. We believe our culture is essential to the health and success of our business and aligns our employees around a set of behaviors and actions that foster passion and commitment. Facilities We are headquartered in Seattle, Washington. Our current facility in Seattle has approximately 70,000 square feet under a lease that expires December 2026. The lease provides for an early termination right beginning in December 2022, subject to early termination fees. We also lease a design laboratory and demonstration center located in Seattle, with approximately 11,000 square feet. The lease expires October 2018, subject to an option to extend for either one or three additional years. We also have a satellite sales office in Shanghai and California. Legal Proceedings As of the date of this report, we are not a party to any material legal proceedings. In the normal course of business, we may be named as a party to various legal claims, actions and complaints. We cannot predict whether any resulting liability would have a material adverse effect on our financial position, results of operations or cash flows. Financial Information about Segments and Geographic Revenue We operate as one operating segment. See Note 10 to our audited consolidated financial statements included in this report. For financial information regarding our business, see Part II—Item 7—"Management's Discussion and Analysis of Financial Condition and Results of Operations" of this report and our audited consolidated financial statements and related notes included elsewhere in this report. 13 Corporate Information We were incorporated in Delaware in April 2 000. Our principal executive office is located at 400 Fairview Avenue North, Suite 1200, Seattle, Washington 98109. Our telephone number is (206) 517-5300. Our website is www.impinj.com . Information contained in, or that can be accessed through, our website is not a part of, and is not incorporated into, this report. Item 1A. Risk Factors Investing in our common stock involves a high degree of risk. Before making an investment decision, you should carefully consider the risks and uncertainties described below, which we believe are the material risks of our business. In addition, risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and operating results. Our business, financial condition, operating results or growth prospects could be harmed by any of these risks. In such an event, the trading price of our common stock could decline, and you may lose all or part of your investment. In assessing these risks, you should also refer to all of the other information contained in this report, including our consolidated financial statements and related notes. Risks Related to Our Business and Industry RAIN market adoption is uncertain. If RAIN market adoption does not continue to develop, or develops more slowly than we expect, our business will suffer. The RAIN market is relatively new and, to a large extent, unproven. RAIN technology and product adoption, including that of the Impinj Platform and Item Intelligence, will depend on numerous factors, including: • • • whether end users embrace the benefits we believe RAIN offers, and if so whether RAIN will achieve and sustain high demand and market adoption; whether end users perceive that the benefits of RAIN adoption outweigh the cost and time to install or replace their existing systems and processes; and whether the technological capabilities of RAIN products and applications meet end users’ current or anticipated needs. The adoption of RAIN technology and products has historically been slower than anticipated or forecasted by us and industry sources. Our industry has also experienced periods of accelerated adoption that were not sustained. For example, RAIN adoption accelerated in late 2010 and early 2011, but then decelerated, in part, we believe, due to a patent infringement lawsuit filed by Round Rock Research in 2011 against several large retailers and other end users. Round Rock settled with RAIN suppliers in late 2013, however the end users that were parties to the lawsuit did not finalize their settlements with Round Rock until early 2015. Near-term RAIN adoption depends on large organizations with market influence, particularly in the retail industry, continuing to deploy RAIN solutions. Long-term RAIN market growth will depend on adoption by other industries and government agencies. End users and our prospective customers may not be familiar with our products or RAIN in general, or may use other products and technologies to identify, locate, authenticate, engage, track and prevent loss of their items. Additionally, even if prospective customers are familiar with RAIN, our products or Item Intelligence, a negative perception of, or experience with, RAIN or a competitor’s RAIN products may deter them from adopting RAIN or our products. Before they adopt RAIN, businesses, government agencies and other organizations may need education on the benefits of using RAIN in their operations. These educational efforts may not be successful, and organizations may decide that the costs of adopting RAIN outweigh the benefits. Failure of organizations to adopt RAIN generally, and the Impinj Platform specifically, for any reason will hurt the development of our market and, consequently, impair our business and prospects. 14 Fluctuations in the adoption of RAIN may affect our ability to forecast our future operating results, including revenue, gross margins, cash flows and profitability. Moreover, to ensure adequate inventory supply, we must f orecast inventory needs and expenses and place orders sufficiently in advance with our suppliers and contract manufacturers based on our estimates of future demand for particular products. In the near term, we expect to invest significantly in endpoint IC and gateway inventory to support the projected growth in our business. Our failure to accurately forecast demand for RAIN solutions may cause us to experience excess inventory levels or a shortage of products available for sale. If RAIN adoption by retailers does not continue at the rate we expect, our business will be adversely affected. The retail apparel industry leads RAIN adoption, and end users in the retail industry were the largest consumers of our endpoint ICs in 2016. We believe the retail industry is a leading indicator of RAIN market adoption and if large apparel retailers in particular continue adopting our platform then adoption within the retail industry and in other industries will accelerate. As such, the retail industry is one of our key strategic foci. If retailers or other early adopters fail to realize demonstrable benefits from RAIN or delay or abandon their deployments, overall RAIN market acceptance may be materially and adversely affected. For example, in July 2012, J.C. Penney Company, Inc. announced plans to connect every item in their stores by February 2013; however, they subsequently stopped the RAIN deployment after experiencing challenging financial results and a change in senior management. Other retailers that have a primarily physical presence in the marketplace have experienced financial stress in recent periods. Many of these retailers have deployed RAIN to improve competitiveness; however, if they fail to compete effectively, the number of stores they maintain, and thus the scope of their RAIN deployments, may decrease significantly. Any widespread delay, slowdown or failure by retailers or other organizations to implement RAIN-based systems generally, and our products and the Impinj Platform specifically, will materially and adversely affect our business, operating results, financial condition and long-term prospects. We have a history of losses and only recently achieved profitability. We cannot be certain that we will increase or sustain profitability in the future. We have incurred losses since our inception in 2000 and only first became profitable in 2013. Although we had net income of $900,000 for 2015, we had a net loss of $1.7 million for 2016 and an accumulated deficit of $187.2 million as of December 31, 2016. Our ability to increase or sustain profitability depends on numerous factors, many of which are out of our control, including continued RAIN adoption, our market share and our margins. We expect significant expenditures to support operations, product development, and business and headcount expansion in sales, engineering, and marketing as a public company. If we fail to increase our revenue or manage our expenses, we may not increase or sustain profitability in the future. Fluctuations in our quarterly and annual operating results may adversely affect our business, prospects and stock price. You must consider our business and prospects in light of the risks and difficulties we encounter in the uncertain and rapidly evolving RAIN market. Because this market is new and evolving, predicting its future growth rate and size is difficult. The rapidly evolving nature of the markets in which we sell our products, as well as other factors that are beyond our control, reduce our ability to accurately evaluate our future prospects and forecast quarterly or annual performance. End users drive demand for our products. Because we sell nearly all of our products through channel partners, our ability to determine end-user demand is limited. For example, 2016 endpoint IC sales exceeded both our expectations and those of our industry’s analysts. Although we expect future-period endpoint-IC growth rates to return to a more-typical CAGR, roughly in-line with the growth expectations of RAIN industry analysts, in the near term we are investing in endpoint IC inventory both to meet forecast demand, competitively reduce lead times and to enhance our ability to deliver in the event of another unexpected demand surge. In addition, we rely on our channel partners to integrate our products with end-user information systems and this integration has been uneven and unpredictable in scope, timing and implementation. Partly as a consequence, in the past, both we and other industry participants have at times overestimated the RAIN market size and growth rates, then failed to meet expectations. 15 To date , we have had limited success in accurately predicting future sales of our products and platform. We expect that for the foreseeable future our visibility into future sales, including both volumes and prices, will continue to be limited. This poor visibili ty may cause fluctuations in our operating results, particularly on a quarterly basis, that we are unable to predict as well as failure to achieve our expected operating results. In addition, if endpoint IC sales (one indicator of market adoption) exceed expectations or if we discount prices to win a particularly large opportunity or in response to competition, our revenue and profitability may be positively affected, but gross margins may be negatively affected depending on product mix for the applicable period. If research analysts or investors perceive such product mix shift negatively, the trading price of our common stock could be adversely affected. Numerous other factors, many of which are outside our control, may cause or contribute to significant fluctuations in our quarterly and annual operating results. These fluctuations may make financial planning and forecasting difficult. In addition, these fluctuations may result in unanticipated decreases in our available cash, which could negatively affect our business and prospects. Factors that may contribute to fluctuations in our operating results and revenue include: • • • • • • • • • • • • • • • variations in RAIN adoption and deployment delays by end users; fluctuations in demand for our products, the Impinj Platform or Item Intelligence, including by tag manufacturers and other significant customers on which we rely for a substantial portion of our revenue; fluctuations in the available supply of our products; variations in the quality of our products and return rates; declines in selling prices for our products; delays in our product-shipment timing, customer or end-user sales or deployment cycles, or work performed under development contracts; intellectual property disputes involving us, our customers, end users or other participants in our industry; adverse outcomes of litigation or governmental proceedings; timing variability in product introductions, enhancements, services, and technologies by us and our competitors and market acceptance of these new or enhanced products, services and technologies; unanticipated excess or obsolete inventory as a result of supply-chain mismanagement, new-product introduction, quality issues or otherwise; changes in the amount and timing of our operating costs, including those related to the expansion of our business, operations and infrastructure; changes in business cycles or seasonal fluctuations that may affect the markets in which we sell; changes in industry standards or specifications, or changes in government regulations, relating to RAIN, the Impinj Platform, or Item Intelligence; late, delayed or cancelled payments from our customers; and unanticipated impairment of long-lived assets and goodwill. A substantial portion of our operating expenses are fixed for the short-term, and as a result fluctuations in revenue or unanticipated expenses can have a material and immediate impact on our profitability. The occurrence of any one of these risks could negatively affect our operating results in any particular period, which could cause the price of our common stock to decline. 16 Our market is very competitive. If we fail to compete successfully, our business and operating results will suffer. We face significant competition from both established and emerging competitors. We believe our principal current competitors are: in readers and gateways, Zebra and Alien Technology Corporation, or Alien; in reader ICs, STMicroelectronics and Phychips Inc.; and in endpoint ICs, NXP, which in October 2016 entered into a definitive agreement to be acquired by Qualcomm, and Alien. Our channel partners, including distributors, system integrators, VARs, and software solution partners, may enter our market and compete with us rather than purchase our products, which would not only reduce our customer base but also increase competition in the market, adversely affecting our operating results, business and prospects. In addition, companies in adjacent markets or newly formed companies may decide to enter our market, particularly as RAIN adoption grows. For example, Qualcomm could use its NXP acquisition as an entry point into the RAIN market. Competition for customers is intense. Because the RAIN market is evolving rapidly, winning customer and end-user accounts at an early stage in the development of the market is critical to growing our business. End users that instead use competing products and technologies may face high switching costs, which may affect our and our channel partners’ ability to successfully convert them to our products. Failure to obtain orders from customers and end users, for competitive reasons or otherwise, will materially adversely affect our operating results, business and prospects. Some of our competitors may devote more resources than we can to the development, promotion, sale and support of their products. Our competitors include companies that have much greater financial, operating, research and development, marketing and other resources than us. These competitors may discount their products to gain market share. In doing so, they could simply accept smaller margins or they could maintain margins by achieving cost savings through better, more efficient designs or production methods. To gain share, competitors could also bundle near-field communication, or NFC, products with RAIN products, or stationary readers with handheld readers. New competitors could enter the gateway market or develop RAIN platforms or solutions. Larger or more established companies may deliver and directly compete with our Item Intelligence. Smaller companies could launch new products and applications we do not offer and could gain market acceptance quickly. Moreover, consolidation in the RAIN industry could intensify the competitive pressures that we face. Many of our existing and potential competitors may be better positioned than we are to acquire other companies, technologies or products. Some of our customers have policies requiring diverse supplier bases to enhance competition and maintain multiple RAIN product providers. They do not have an interest in purchasing exclusively from one supplier or promoting a particular brand. Our ability to increase order sizes from these customers and maintain or increase our market share is constrained by these policies. In addition, any decline in quality or availability of our products or any increase in the number of suppliers that such a customer uses may decrease demand for our products and adversely affect our operating results, business and prospects. We cannot assure you that our products will continue to compete favorably or that we will be successful in the face of increasing competition from new products, or enhancements introduced by our existing competitors, or new companies entering our market. In addition, we cannot assure you that our competitors do not have, or will not develop, processes or product designs that currently or in the future will enable them to produce competitive products at lower costs than ours. Any failure to compete successfully will materially adversely affect our business, prospects, operating results and financial condition. 17 Downturns in the industries we serve, particularly retail, may adversely affect our business. Worldwide economic conditions have exhibited significant fluctuations in recent years, and market volatility and uncertainty remain widespread. As a consequence, we and our customers have had extreme difficulty forecasting and planning future business activities accurately. These economic conditions could cause our customers or end users to reduce their capital-expense budgets, which could decrease spending for our products resulting in delayed and lengthened deployment, a decrease in sales or a loss of sales opportunities. The retail industry is subject to volatility, especially during uncertain economic conditions. A downturn in the retail industry in particular may disproportionately affect us because retailers comprise a significant portion of the RAIN end users. We cannot predict the timing, strength or duration of any economic slowdown or recovery, whether global, regional or within specific markets. If the conditions of the general economy or markets in which we operate worsen, our business could be harmed. If we fail to obtain quality products in adequate quantity and in a timely and cost-effective manner, our operating results and growth prospects will be adversely affected. We do not own or operate manufacturing facilities. Currently, all our endpoint ICs are manufactured by Taiwan Semiconductor Manufacturing Company Limited, or TSMC, and primarily post-processed by our subcontractor Stars Microelectronics (Thailand) Public Company Limited, or Stars; all our reader ICs are manufactured by Tower Semiconductors Ltd., or TowerJazz; and all our readers and gateways are manufactured by Plexus Corp., or Plexus, or Western Corporation. We also use subcontractors for post-processing, assembly and testing. We do not control our manufacturers’ or subcontractors’ ability or willingness to meet our supply requirements. Currently, we do not have long-term supply contracts with TSMC, TowerJazz, Plexus or Western Corporation, and neither they nor our subcontractors are required to supply us with products for any specific period or in any specific quantity. Suppliers can allocate production capacity to other companies’ and reduce deliveries to us on short notice. Our suppliers may allocate capacity to other companies, which could impair our ability to secure sufficient product supply for sale. We place orders with some of our suppliers five or more months before our anticipated product delivery dates to our customers. We base these orders on our customer-demand forecasts. If we inaccurately forecast this customer demand then we may be unable to obtain adequate and cost-effective foundry or assembly capacity to meet our customers’ delivery requirements, or we may accumulate excess inventory. Manufacturing capacity may not be available when we need it or at reasonable prices. For example, in 2010 we experienced wafer shortages from TSMC relative to our submitted endpoint IC purchase orders because of high worldwide demand for semiconductor foundry capacity. These shortages adversely affected our ability to meet our customers’ demand and, in some cases, caused customers to cancel orders, qualify alternative suppliers or purchase from our competitors. As another example, in mid-2016, as a consequence of rapid growth in endpoint IC demand, we depleted our endpoint IC buffer stock and were temporarily unable to satisfy demand for all customers, causing some customers to purchase from alternative suppliers even as we increased our wafer orders from TSMC, ramped our wafer post-processing and rebuilt our inventory. In response to any future shortages, our customers may act similarly or, alternatively, may overbuy our products, which could artificially inflate sales in near-term periods while leading to sales declines in future periods as our customers consume their accumulated inventory. At times, our suppliers ask us to purchase excess products to ensure we do not face a subsequent shortage. For example, in the second quarter of 2014, we purchased more ICs from TSMC than required, which affected our available cash for the quarter. In addition, we may invest significantly in inventory to support projected growth in our business, as we expect to do with endpoint IC inventory in 2017. If we are unable to sell the additional inventory we purchased, or if we must sell it at lower prices due to obsolescence, our operating results may be adversely affected. 18 If our suppliers fail to deliver products at reasonable prices or with satisfactory quality levels then our ability to bring products to market and our reputation could suffer. For example, if supplier capacity dimin ishes, including from a catastrophic loss of facilities or otherwise, we could have difficulty fulfilling our orders, our revenue could decline and our growth prospects could be impaired. We anticipate requiring three to 18 months to transition our assembl y services or foundries to new providers. Such a transition would likely require a qualification process by our customers or end users, which could also adversely affect our ability to sell our products and our operating results. If we are unsuccessful introducing new products and enhancements, our operating results will be harmed. To keep pace with technology developments, satisfy increasingly stringent end-user requirements and achieve market acceptance, we plan to introduce new products and solutions. We commit significant resources to developing these new products and solutions while improving performance, reliability and reducing costs. For example, we are investing substantial resources to develop and enhance our operating-system software but do not expect to realize material revenue from this software in the near future. The market for our software is nascent, and we need to create market awareness of its benefits to drive end-user adoption. Creating market awareness includes promoting our software as a foundation on which end users, ISVs, consultants, system integrators, or SIs, and others can develop applications that meet end-user needs and drive adoption. We may be late in delivering or improving our software to meet our partners’ needs. In addition, we have limited experience developing and selling software products and cannot be certain that our proposed pricing model, sales strategy, or software quality and reliability will be successful. We rely on and must train our channel partners to sell, develop applications for and integrate our software with end users’ systems, but we cannot guarantee that we or they will be successful doing so. We believe that we must continue to dedicate a significant amount of resources to our development efforts to maintain our competitive position. We also cannot be certain that our software will generate revenue from these investments for several years, if it all, or that such revenue will exceed the investment we are committing to develop and deploy our software. The success of a new or enhanced product is impacted by accurate forecasts of long-term market demand. For example, our xArray and xSpan gateways are relatively new products that incorporate enhanced technological features, but we cannot be certain whether demand for such gateways will develop as forecasted. We may also fail to anticipate or meet market requirements for new features and functionality. By focusing on certain new products and industries, we may miss opportunities for other products and applications that may be more widely adopted. In addition, we enter into non-recurring engineering, or NRE, development agreements which typically include initial funding with a requirement for us to meet certain milestones in order to receive additional funding for the NRE engagement. If we are unable to meet such milestones, we may not realize the full benefits of the NRE engagement. If we fail to introduce new or enhanced products in a timely fashion to meet our channel partners’ or end-users’ needs or do not achieve the milestones in our NRE engagements then we will lose market share and our revenue and financial condition could be materially adversely affected. If we are unable to develop new products using new or enhanced technologies, our competitive position will be adversely affected. In the future, we may not succeed in developing the underlying technologies or processes necessary to create new or enhanced products or license or otherwise acquire these technologies from third parties. In some instances we may be late to market with our innovations, or may choose to be a “fast follower” but subsequently be unable to overcome the lead we gave to our competition. The success of a new or enhanced product depends on technological developments, market positioning and timing, as well as on various implementation factors, including: • • • our timely and efficient completion of the design process; our timely and efficient implementation of manufacturing, assembly and testing procedures; product performance; 19 • • • product certification; the quality, reliability and selling price of the product; and effective marketing, sales and service. If we are unable to develop new products or features to compete effectively, our market share will be adversely affected, which would harm our business, financial condition and operating results. An inability or limited ability of enterprise systems to exploit RAIN information may adversely affect the market for our products. A successful end-user RAIN deployment requires not only tags and readers or gateways, but integration with information systems and applications that derive business value from endpoint data. Unless technology providers continue developing and advancing business-analytics tools, and end users install or enhance their information systems and applications to use these tools, deployments of RAIN products and applications could stall. Our efforts to foster development and deployment of these tools by providing software that delivers Item Intelligence could fail. In addition, our guidance to business-analytics tool providers for integrating our products with their tools could prove ineffective. Solution providers and systems integrators form an essential part of the RAIN market by providing deployment know-how to end users who are unable to deploy RAIN solutions on their own. Our efforts to train and support these solution providers and systems integrators could fail. Further, integrating our products with end-user information systems could prove more difficult or time consuming than we or they anticipate, which could delay deployments. If end users are unable to successfully exploit RAIN data, or if we are unable to support solution providers or systems integrators adequately, or if deployments of our platform are delayed, we could see a material adverse impact on our business, operating results, financial condition or prospects. Our reliance on a small number of customers could adversely affect our business and operating results. In 2016, sales to Smartrac, Avery, Arizon and Shang Yang accounted for 16%, 14%, 11% and 10% of our total revenue, respectively. We sell our endpoint ICs directly to inlay and tag original equipment manufacturers, or OEMs, and original design manufacturers, or ODMs. We sell our reader ICs to reader OEMs and ODMs, primarily through distribution. We sell our readers and gateways to VARs and SIs primarily through distribution; we are beginning to sell software through these same partners as well as through ISV partners. We have experienced in the past and may again experience in the future purchasing delays or disruptions by some of these channel partners due to conditions within their organizations that are independent of market demand for our products or the RAIN market generally. Although our strategy is to diversify our partner base by pursuing increased orders from smaller partners, add new partners, and increase end-user pull for our products, we cannot assure you we will succeed in doing so. The number of tag OEMs may decrease by consolidation or otherwise. Even if we are successful in obtaining and retaining new partners, our small number of existing large tag OEMs may continue to account for a substantial portion of our future sales. Changes in markets, channel partners, end-user customers, products, negative economic or financial developments, or poor or limited credit availability may adversely affect the ability of our tag OEMs, reader and gateway partners and distributors to bring our products to market. Our future performance will depend, in part, on our ability to attract new tag OEMs, reader and gateway partners and distributors that use, market and support our products effectively, especially in market segments where we have not sold products previously. If we cannot retain our current tag manufacturers, reader and gateway partners and distributors or establish new relationships, our business, financial condition and operating results could be harmed. In addition, our competitors’ strategic relationships with or acquisitions of these tag OEMs, reader and gateway partners or distributors could disrupt our relationships with them. Any such disruption could impair or delay our product sales to end users and increase our costs of distribution, which could adversely affect our sales or operating results. 20 Our reliance on distributors, system integrators, VARs and software solution providers to sell and distribute our products to end users could harm our business and revenue. We rely on our partner ecosystem to sell and distribute our products to end users. Our revenue depends on their ability to successfully market, sell, install and provide technical support for the solutions in which our products are integrated or to sell our products on a standalone basis. Our revenue will decline if our channel partners fail. Further, faulty or negligent implementation and installation of our products by systems integrators may harm our reputation. Because we fulfill through channel partners, our ability to determine end-user demand is constrained. End users drive demand for our products and because we are often at least one step removed from these end users, we may be unable to rectify damage to our reputation caused by our channel partners who have more direct contact with these end users. For strategic or other reasons, our channel partners may choose to prioritize the sale of our competitors’ products over our products. Furthermore, some of our channel partners may offer some products that compete with our products and may limit sales of our competing products. If reader IC OEMs are unable to obtain components for products in which our products are included, our product sales could be adversely affected. If our distributors, system integrators, VARs or software solution providers are unable to sell an adequate amount of our products in a given quarter or if they choose to decrease their inventories of our products for any reason, our sales to these channel partners and our revenue will decline. Many of our channel partners provide us with customer referrals and cooperate with us in marketing our products; however, our relationships with them may end at any time. If we fail to successfully manage our relationships with our channel partners, our ability to sell our products into new industries and to increase our penetration into existing industries may be impaired and our business will be harmed. If our channel partners do not properly forecast end users’ demand for our products then they may carry excess product inventory, which could adversely affect our revenue and operating results. If some or all of our channel partners purchase more of our products than they need to satisfy end-user demand in any particular period, inventories held by the channel partners will grow during that period. The channel partners are then likely to reduce future orders until they realign inventory levels with end-user demand, which could adversely affect our product revenue in a subsequent period. Distributors may also return our products in exchange for other products, subject to time and quantity limitations. Our reserve estimates for products stocked by our distributors are based principally on reports provided to us by our distributors, typically on a monthly basis. To the extent this resale and channel-inventory information is inaccurate or we do not receive it in a timely manner, we may not be able to make accurate reserve estimates for future periods, which could adversely affect our operating results. Our growth strategy depends in part on the success of strategic relationships with third parties and their continued performance and alignment. To continue our growth, we are investing in our relationships with system integrators, VARs and software solution providers that have product offerings that complement our platform and through which we will fulfill sales. Our business will be harmed if we fail to successfully develop and implement such strategic relationships. For example, operating results may suffer if our efforts towards developing our go-to-market relationships consume resources and incur costs, but do not result in a commensurate increase in revenue. In addition, such relationships may involve exclusivity provisions, additional levels of distribution, discount pricing or investments in other companies. The cost of developing and maintaining such relationships may go unrecovered or unrewarded and our efforts may not generate a correspondingly significant increase in revenue. Selling prices of our products could decrease substantially, which could have a material adverse effect on our revenue and gross margins. Historically, our market has experienced price erosion. The average selling prices, or ASPs, of our products has decreased as the RAIN market has developed. We may experience substantial fluctuations in future operating results due to further ASP reductions. 21 From time-to-time we reduce the selling prices of our products to meet end-customer demands or due to market pressure from our competition. As the market has grown, we have generally seen competitive pressures increase. W e also sometimes reduce prices to encourage adoption, address macroeconomic conditions or for other reasons. We expect to do so again in the future. If we are unable to offset ASP reductions with increased sales volumes or reduced product costs then our re venue and gross margins will suffer. Further, our customers may be slow to migrate to new, higher margin products. Some competitors have significantly greater resources than we have and may be better able to absorb the negative impact on operating results as a result of such trends. Rapid market innovation, which we continue to experience, can drive intense pricing pressure, particularly for older products or products using older technology. Short product life cycles cause our channel partners and end users to replace older products with newer ones on a regular basis. When demand for older products declines, ASPs may drop, in some cases precipitously. To profitably sell our products we must continually improve our technology, processes, and reduce costs in line with the lower selling prices. If we and our third-party suppliers and manufacturers cannot advance process technologies or improve efficiencies to a degree sufficient to maintain required margins, we may not be able to sell our products profitably. Should our cost reductions fail to keep pace with reductions in market prices, our business, financial condition and operating results will be materially adversely affected. Changes in our product mix could cause our overall gross margin to decline, adversely affecting our operating results and financial condition. We cannot assure you that we will be able to maintain our historical gross margins. Our gross margins depend strongly on product mix. A shift in sales mix away from our higher margin products to lower margin products will adversely affect our gross margins. A majority of our revenue is generated by sales of our endpoint ICs, which have lower gross margins than our other products, and endpoint IC revenue may continue increase as a percentage of our total revenue over time. In addition, gross margins can be affected by endpoint IC product mix. As the market for our newer, higher-margin endpoint IC products matures, we expect to experience price erosion for those products which may adversely affect gross margins if we are not able to realize cost reductions or shift towards newer or other higher margin products. If endpoint IC revenue continues to grow relative to our other products, our company-wide gross margin will decline. NRE developments generally also have a higher margin than endpoint ICs, and their impact on our gross margin may vary. For example, in the second half of 2013 and first half of 2014 we generated a substantially larger percentage of our revenue from NRE engagements, which resulted in a higher gross margin for such periods. Additionally, competitive alternatives to our products, overall increased competition, weaker than expected demand, currency exchange rates and other factors may lead to lower prices, revenue and margins in the future, adversely affecting our operating results and financial condition. We generate most of our revenue from our endpoint ICs, and a decline in sales of these products could adversely affect our operating results and financial condition. We derive, and expect to continue to derive, a majority of our product revenue from our endpoint ICs. In addition, the continued adoption of our endpoint ICs derives in part from our ability to sell our reader ICs, readers and gateways. We are particularly vulnerable to fluctuations in demand for our endpoint ICs, and if demand for them declines, our business and operating results will be adversely affected. 22 Our products must meet exacting technical and quality specifications. Defects, errors or interoperability issues with o ur products, or the failure of our products to operate as expected, could affect our reputation, result in significant costs to us and impair our ability to sell our products. Our products may contain defects or errors or may not operate as we or our channel partners or end-user customers expect, which could materially and adversely affect our reputation, result in significant costs to us and impair our ability to sell our products in the future. Our products must meet demanding specifications for quality, performance and reliability. Our products are highly technical and designed to be deployed in large, complex systems under a variety of conditions. Channel partners and end users may discover errors, defects or incompatibilities only after deploying our products. For example, harsh environments or radio-frequency interference may negatively affect gateway performance. In addition, our channel partners or end users may experience compatibility or interoperability issues between our products and their enterprise software systems or networks, or between our products and other RAIN products they may use. We may experience quality problems with our products combined with or incorporated into products from other vendors, such as tags produced by our tag OEMs using our endpoint ICs, or readers or gateways assembled by OEMs and ODMs using our reader ICs. We may have difficulty identifying and correcting the source of problems when third parties are combining, incorporating or assembling our products. If we are unable to fix errors or other problems, we could experience: • • • • • • • • • • loss of customers or customer orders; lost or delayed market acceptance and sales of our products; loss of market share; damage to our brand and reputation; impaired ability to attract new customers or achieve market acceptance; diversion of development resources; increased service and warranty costs; replacement costs; legal actions by our customers; and increased insurance costs. Although our agreements typically contain provisions that purport to limit our liability for damages resulting from defects in our products, such limitations and disclaimers may not be enforceable or otherwise effectively protect us from claims. We may be required to indemnify our customers against liabilities arising from defects in our products or in their solutions that incorporate our products. These liabilities may also include costs incurred by our channel partners or end users to correct problems or replace our products. The costs we incur correcting product defects or errors may be substantial and could adversely affect our operating results. Although we test our products for defects or errors prior to product release and during production, our customers still occasionally catch defects or errors that we miss. Such defects or errors have occurred in the past and may occur in the future. To the extent product failures are material, they could adversely affect our business, operating results, customer relationships, reputation and prospects. Also, we assert that our products conform to the UHF Gen2 protocol. Compatibility issues between our products and the protocol, or among different products that each nominally conform to the protocol, could disrupt our customers’ operations, hurt our customer relations and materially adversely affect our business and prospects. 23 We will lose market share and may not be successful if end users or customers do not design our products into their products and systems. End users often undertake extensive pilot programs or qualification processes prior to placing orders for large quantities of our products, in particular for gateway products, because these products must function as part of a larger system or network or meet certain other specifications. We spend significant time and resources to have our products selected by a potential end user or customer, which is known as a “design-in.” In the case of gateway products, a “design-in” means that the gateway product has been selected to be designed into the end user’s system and, in the case of a tag, may mean the tag has met certain unique performance criteria established by the end user or customer. If we fail to develop new products that adequately or competitively address the needs of potential end users, they may not select our products to be designed into their systems, which could adversely affect our business, prospects and operating results. Our business is dependent upon our brand recognition and reputation, and if we fail to maintain or enhance our brand recognition or reputation, our business could be harmed. We believe that maintaining and enhancing our brand and our reputation are critical to our relationships with our customers and end users and to our ability to attract new customers and end users. We also believe that our brand and reputation will be increasingly important as competition in our market continues to develop. Our success in this area will depend on a wide range of factors, some of which are beyond our control, including the following: • • • • • • • • • the efficacy of our marketing efforts; our ability to continue to offer high-quality, innovative and defect-free products; our ability to maintain the security and privacy of our customers’ sensitive and proprietary information; our ability to retain existing customers and obtain new customers; our ability to maintain high customer satisfaction; the quality and perceived value of our products; our ability to successfully differentiate our products from those of our competitors; actions of competitors and other third parties; and positive or negative publicity. If our brand promotion activities are not successful, our operating results and growth may be harmed. Furthermore, negative publicity, whether or not justified, relating to events or activities attributed to us, employees, channel partners or others associated with any of these parties, may tarnish our reputation and reduce the value of our brand. Damage to our reputation and loss of brand equity may reduce demand for our products and platform and have an adverse effect on our business, operating results and financial condition. Moreover, any attempts to rebuild our reputation and restore the value of our brands may be costly and time consuming, and such efforts may not ultimately be successful. 24 If we are unable to protect our intellec tual property then our business could be adversely affected. Our success depends in part upon our ability to obtain, maintain and enforce patents, trade secrets, trademarks and other intellectual property rights and to operate without infringing on the proprietary rights of others or having third parties infringe, misappropriate or circumvent the rights we own or license. We rely on a variety of intellectual property rights, including patents in the United States and copyrights, trademarks and trade secrets in the United States and foreign countries. Because most RAIN products are used in or imported into the United States, we have historically focused on filing U.S. patent applications. We have filed a small number of foreign patent applications, but do not yet have any issued or allowed patents in any foreign country. By seeking patent protection primarily in the United States, our ability to assert our intellectual property rights outside the United States is limited. We have registered trademarks and domain names in selected foreign countries where we believe filing for such protection is appropriate. Regardless, some of our products and technologies may not be covered adequately by any patent, patent application, trademark, copyright, trade secret or domain name. We cannot guarantee that: • • • • • • • any of the patents, trademarks, copyrights, trade secrets or other intellectual property rights we presently employ in our business will not lapse or be invalidated, circumvented, challenged or abandoned; our intellectual property rights will provide competitive advantages to us; our ability to assert our intellectual property rights against potential competitors or to settle current or future disputes will not be limited by our agreements with third parties; any of our pending or future patent applications will be issued or have the coverage we originally sought; our intellectual property rights will be enforced, particularly in jurisdictions where competition may be intense or where legal protections may be weak; we will not lose the ability to assert our intellectual property rights against, or to license our technology to, others and collect royalties or other payments; or we will retain the right to ask for a royalty-bearing license in relation to ratification of a standard for which we participate in the standards process if we fail to file an intellectual property declaration pursuant to such standards process. In addition, our competitors or others may design around our patents or protected technologies. Effective intellectual property protection may be unavailable or more limited in one or more relevant jurisdictions relative to those protections available in the United States. If we pursue litigation to assert our intellectual property rights, an adverse decision in any legal action could limit our ability to assert our intellectual property rights, limit the value of our technology or otherwise negatively impact our business, financial condition and operating results. Monitoring unauthorized use of our intellectual property is difficult and costly. Unauthorized use of our intellectual property may have already occurred or may occur in the future. Our failure to identify unauthorized use or otherwise adequately protect our intellectual property could adversely affect our business. Moreover, any litigation could be time consuming, and we could be forced to incur significant costs and divert our attention and the efforts of our employees, which could, in turn, result in lower revenue and higher expenses. Some of our know-how or technology is not patented or patentable and may constitute trade secrets. To protect our trade secrets, we have a policy of requiring our employees, consultants, advisors and other collaborators to enter into confidentiality agreements. We also rely on customary contractual protections with our channel partners, suppliers and end users, and we implement security measures intended to protect our trade secrets, know-how or other proprietary information. However, we cannot guarantee we have entered into appropriate agreements with all parties that have had access to our trade secrets, know-how or other proprietary information. We also cannot assure you that those agreements will provide meaningful protection for our trade secrets, know-how or other proprietary information in the event of any unauthorized use or disclosure. Our trade secrets, know-how or other proprietary information could be obtained by third parties as a result of breaches of our physical or electronic security systems or our suppliers, employees or consultants could assert rights to our intellectual property. 25 Finally, our use of overseas manufacturers may involve particular risks. The intellectual property protection in countries where our third-party contractors operate is weaker t han in the United States. If the steps we have taken and the protection provided by law do not adequately safeguard our intellectual property rights then we could suffer losses in profits due to the sales of competing products that exploit our intellectual property rights. We may face claims of intellectual property infringement which could be time consuming, costly to defend or settle, result in the loss of significant rights, and adversely affect RAIN adoption generally. Many companies in our industry hold large numbers of patents and other intellectual property rights and may vigorously pursue, protect and enforce their intellectual property rights. We have in the past, and may in the future, receive invitations to license patent and other intellectual property rights to technologies that are important to our business. We may also receive assertions against us, our channel partners or end users claiming that we or they infringe patent or other intellectual property rights. Claims that our products, processes, technology or other aspects of our business infringe third-party intellectual property rights, regardless of their merit or resolution, could be costly to defend or settle and could divert the efforts and attention of our management and technical personnel. If we decline to accept an offer, the offering party may allege that we infringe such patents, which could result in litigation. Intellectual property disputes affecting our industry may adversely affect RAIN adoption. For example, in 2011 Round Rock Research filed lawsuits against 11 end users, including Walmart and Macy’s, for patent infringement in the RAIN products these retailers use. We believe these lawsuits materially and adversely affected demand for our products by retailers and others from 2011 to 2014. In 2013, Round Rock Research entered into licensing settlement agreements with a substantial number of RAIN vendors, including us; in early 2015, they reached a settlement agreement with the last of the end-user defendants. We, our channel partners, suppliers or end users could be involved in similar disputes in the future which would materially and adversely affect our operating results and growth prospects. Many of our agreements require us to indemnify and defend our channel partners and end users from third-party infringement claims and pay damages in the case of adverse rulings. Moreover, we may not know whether we are infringing a third party’s rights due to the large number of RAIN-related patents or to other systemic factors. For example, patent applications in the United States are maintained in confidence for up to 18 months after filing or, in some instances, for the entire time prior to patent issuance. Consequently, we may not be able to account for such rights until after publication. Competitors may also have filed patent applications or received patents and may obtain additional patents and proprietary rights that block or compete with our patents. Claims of this sort could harm our relationships with our channel partners or end users and might deter future customers from doing business with us. We do not know whether we will prevail in any such future proceedings given the complex technical issues and inherent uncertainties in intellectual property litigation. If any pending or future proceedings result in an adverse outcome then we could be required to: • • • • • • cease the manufacture, use or sale of the infringing products, processes or technology; pay substantial damages for infringement; expend significant resources to develop non-infringing products, processes or technology; license technology from the party claiming infringement, which license may not be available on commercially reasonable terms, or at all; cross-license our technology to a competitor to resolve an infringement claim, which could weaken our ability to compete with that competitor; or pay substantial damages to our channel partners or end users to cause them to discontinue their use of, or replace, infringing products with non- infringing products. Any of the foregoing results could have a material adverse effect on our business, financial condition and operating results. 26 We have limited visibility into the length of the sales and deployment cycles for our products. Because we have limited sales history for our products, we have limited visibility into the lengths of the product sales and deployment cycles, and from time-to-time these cycles have been longer than we anticipated. For new types of products, such as our gateways and ItemSense software, our visibility into the sales and deployment cycle lengths is even more limited; inasmuch as these products are components in a systems sale, our experience in the systems-selling cycle is yet even more limited. Numerous factors can contribute to uncertainties in the cycle lengths, including the time channel partners and end users spend evaluating our products, our time educating them on the products’ benefits, and our time integrating our systems with their systems. The length and uncertain timing of the sales and deployment cycles can lead to delayed product orders. In anticipation of product orders, we may incur substantial costs before the sales cycle is complete and before we receive any customer orders or payments. If a sale is not completed or is cancelled or delayed, we may incur substantial expenses, which could hinder our ability to achieve or maintain profitability or otherwise negatively affect our financial results. Significant developments stemming from the recent change in the U.S. presidential administration or the U.K.’s referendum on membership in the EU could have a material adverse effect on us. In January 2017, Mr. Donald J. Trump was inaugurated as president of the United States. President Trump has since announced his intentions to begin renegotiating NAFTA, and ordered the withdrawal of the United States from negotiations for the TPP; he has also previously proposed restrictions on free trade generally and significant increases in tariffs on goods imported into the United States, particularly from China. Changes in U.S. social, political, regulatory and economic conditions or in laws and policies governing foreign trade, manufacturing, development and investment in the territories and countries where we currently develop and sell products, and any negative sentiments towards the United States as a result of such changes, could adversely affect our business. In addition, negative sentiments towards the United States among non-U.S. customers and among non-U.S. employees or prospective employees could adversely affect sales or hiring and retention, respectively. To the extent U.S. policies engender an economic downturn, in the United States or abroad, the effects could materially affect our business, in many ways only some of which we can identify as of the date of this report. In June 2016, the United Kingdom held a referendum and voted in favor of leaving the European Union, or EU. This referendum has created political and economic uncertainty, particularly in the United Kingdom and the EU, and this uncertainty may last for years. Our business in the United Kingdom, the EU, and worldwide could be affected during this period of uncertainty, and perhaps longer, by the impact of the United Kingdom’s referendum. There are many ways in which our business could be affected, only some of which we can identify as of the date of this report. The referendum, and the likely withdrawal of the United Kingdom from the EU it triggers, has caused and, along with events that could occur in the future as a consequence of the United Kingdom’s withdrawal, including the possible breakup of the United Kingdom, may continue to cause significant volatility in global financial markets, including in global currency and debt markets. This volatility could cause a slowdown in economic activity in the United Kingdom, Europe or globally, which could adversely affect our operating results and growth prospects. In addition, our business could be negatively affected by new trade agreements between the United Kingdom and other countries, including the United States, and by the possible imposition of trade or other regulatory barriers in the United Kingdom. Furthermore, we currently operate in Europe through an Impinj subsidiary based in the United Kingdom, which currently provides us with certain operational, tax and other benefits. The United Kingdom’s withdrawal from the EU could adversely affect our ability to realize those benefits and we may incur costs and suffer disruptions in our European operations as a result. These possible negative impacts, and others resulting from the United Kingdom’s actual or threatened withdrawal from the EU, may adversely affect our operating results and growth prospects. 27 We are subject to order and shipment uncertainties. Inaccuracies in our estimates of end-custome r or channel-partner demand and product mix could negatively affect our inventory levels, sales and operating results. We derive revenue primarily from purchase orders rather than from long-term purchase commitments. To ensure product availability, we typically manufacture from channel-partner forecasts in advance of received purchase orders. Because the RAIN-solutions market is relatively new, many of our channel partners have difficulty accurately forecasting their product requirements and estimating the timing of their new product introductions, which ultimately affects demand for our products. In some cases we build products according to our demand estimates, which requires us to make forecast assumptions. Demand uncertainties, by our channel partners and us, cause significant forecast inaccuracies. Further, our channel partners can cancel purchase orders or defer product shipments, in some cases with little or no advance notice to us. Additionally, we sometimes receive soft commitments for larger order sizes which do not materialize. Because of these reasons, and because we fulfill through channel partners, our visibility into end-user demand is limited, which may adversely affect our ability to plan purchases or manufacturing. Our estimates of channel-partner and end-user demand have historically been inaccurate. Some of the inaccuracies have been material, leading to excess inventory with associated costs or product shortages with its concomitant loss of revenue and gross margin. For example, we believe our 2014 operating results were adversely affected when some retail apparel end users delayed their tag purchases as the result of unexpected extended patent litigation negotiations between certain domestic end users and Round Rock Research. We may experience similar forecasting inaccuracies in the future. When we release new products we may carry higher inventories or have slower inventory turnover depending on our ability to anticipate market acceptance. High inventory levels and increased obsolescence could result in unexpected expenses or increases in reserves that could adversely affect our business, operating results and financial condition. If we underestimate customer demand or if sufficient manufacturing capacity is unavailable, we could miss revenue opportunities, potentially lose market share and damage our customer relationships. Any significant product-order cancellations or deferrals or the return of previously sold products could materially and adversely impact our profit margins, increase our write-offs due to product obsolescence and restrict our ability to fund our operations. If we do not successfully attract and complete custom engineering projects, our products’ market adoption could be delayed and our market position compromised. To extend our products’ capabilities and reach, and to encourage market adoption, we may perform NRE product, tool or software developments. If we do not successfully complete our NRE projects then our customer relationship could deteriorate and we could lose business and opportunities to expand our market. Because NRE-based developments can take more than a year to complete, our time to product revenue can be long. Additionally, a customer may choose to cancel or delay the development, reducing potential revenue. In addition, we compete with other companies to win these NRE engagements and, in the future, we may not be able to compete successfully. Some developments grant time-bounded exclusivity to the customer who paid for the NRE engagement, which may limit our ability to capitalize on the knowledge and experience we gain in connection with the NRE engagement. If a competitor develops and markets a similar product that we are unable to compete due to the time-bounded exclusivity then we could lose business, market share and revenue opportunities. 28 We are subject to risks inherent in foreign operations, including social, political and economic flux and compliance with additional U.S. and international laws, including those related to anti-bribery and anti- corruptio n, and may not be able to successfully maintain or expand our international operations. In 2016, 77% of our total revenue was derived from sales outside the United States. We anticipate growing our business, in part, by continuing to expand our international operations, which involves a variety of risks, including: • • • • • • • • • • • • • • • • • • • changes, some unexpected or unanticipated, in regulatory requirements, taxes, trade laws, tariffs, export quotas, custom duties or other trade restrictions; lack of established, clear, or fairly implemented standards or regulations with which our products must comply; greater difficulty in enforcing contracts, judgments and arbitration awards in international courts, and in collecting accounts receivable and longer payment and collection periods; difficulty in supporting and localizing our international products; different or unique competitive pressures as a result of, among other things, the presence of, or preference for, local businesses and market players; challenges in managing employees, some foreign nationals, over large geographic distances, including the need to implement appropriate systems, policies, benefits and compliance programs; limited or unfavorable intellectual property protection; misappropriation of our intellectual property; inflation and fluctuations in foreign-currency exchange rates and interest rates; withholding taxes or other taxes, or changes thereof, on our foreign income; restrictions, or changes thereof, on foreign trade or investment, including currency exchange controls; changes in a country’s or region’s political, regulatory, legal or economic conditions; political uncertainty, strife, unrest, or conflict; differing regulations with regard to maintaining operations, products and public information; inequities or difficulties obtaining or maintaining export and import licenses; differing labor regulations, including where labor laws may be more advantageous to employees than in the United States restrictions on earnings repatriation; corrupt or unethical practices in foreign jurisdictions that may subject us to exposure under applicable anti-corruption and anti-bribery laws such as the Foreign Corrupt Practices Act and the United Kingdom Bribery Act of 2010, or U.K. Bribery Act; and regulations, and changes thereof, relating to data privacy and the unauthorized use of, or access to, commercial and personal information, particularly in Europe. Various foreign regulatory or other governmental bodies may issue rulings that invalidate prior laws, regulations, or legal frameworks in manners that may adversely impact our business. The European Court of Justice in October 2015 issued a ruling immediately invalidating the U.S.-EU Safe Harbor Framework, which facilitated personal data transfers to the United States in compliance with applicable EU data protection laws. EU and U.S. political authorities adopted the U.S.-EU Privacy Shield on July 12, 2016, which provides a new mechanism for companies to transfer EU personal data to the United States. It is unclear as of the date of this report whether we will make use of the U.S.-EU Privacy Shield, but in view of these developments, there is significant regulatory uncertainty surrounding the future of data transfers from the European Economic Area to the United States. In addition, the European Commission recently adopted a new data- protection regulation, effective in May 2018, that will impose more stringent data-protection requirements than the present regulatory regime in the EU and provide for greater penalties for noncompliance. 29 We opened an office in Shanghai, China in 2011. We are exposed to risks associated with changes in the laws and policies governing Chinese operations and, to a lesser extent, changes in U.S. laws and regulations relating to foreign trade and investment. To date, legal, policy or regulatory changes have not had a material adverse effect on our business or financial condition, but we cannot assure you they will not in the future. We may experience increased costs for, or significant impact to, our Chinese operations in the event of changes in Chinese government policies or political unrest or unstable economic conditions in China. The nationalization or other expropriation of private enterprises by the Chinese government could result in total loss of our Ch ina investment. Any of these matters could materially and adversely affect our business and results of operations. Failure to comply with anti-corruption and anti-bribery laws in our foreign activities could subject us to penalties and other adverse consequences. Anti- corruption and anti-bribery laws generally prohibit companies and their employees and intermediaries from making payments to foreign officials for the purpose of obtaining or keeping business, securing an advantage or directing business to another person, and require companies to maintain accurate books and records and a system of internal accounting controls. Under the U.S. Foreign Corrupt Practices Act of 1977, as amended, or the FCPA, U.S. companies may be held liable for corrupt actions taken by directors, officers, employees, agents, or other strategic or local partners or representatives. If we, our intermediaries or our solution providers, system integrators, OEMs, VARs, distributors, tag manufacturers, and other channel partners fail to comply with FCPA requirements or similar legislation, government authorities in the United States and elsewhere could seek to impose civil or criminal fines and penalties which could have a material adverse effect on our business, operating results and financial conditions. Moreover, China is an area of heightened exposure regarding compliance with anticorruption laws such as the FCPA and the U.K. Bribery Act. We intend to increase our international sales and business there and, as such, our risk of violating laws such as the FCPA or U.K. Bribery Act also increases. We have limited experience marketing, selling and supporting our products and services abroad and may not be able to increase or maintain international market demand for our products. In addition, regulations or standards adopted by other countries may require us to redesign existing products or develop new products for those countries. For example, foreign governments may impose regulations or standards with which our current products do not comply, or may require operation in frequency bands in which our products do not operate. Furthermore, if we are unable to expand international operations in a timely and cost- effective manner in response to increased demand, we could miss sales opportunities and our revenue may decline, adversely affecting our operating results, business and prospects. If we invest substantial time and resources but are unable to expand our international operations successfully and in a timely manner, our business, prospects and operating results will suffer. We generally conduct our China operations through a wholly owned subsidiary and our European operations through our U.K. subsidiary. We generally report our taxable income in worldwide jurisdictions based on our business operations in those jurisdictions. The relevant taxing authorities may disagree with our determinations as to the income and expenses attributable to the jurisdiction or subsidiary. In the event of a disagreement, if our position was not sustained, we could be required to pay additional taxes, interest and penalties, which could result in tax charges, higher effective tax rates, reduced cash flows and lower overall profitability. We are subject to governmental export and import controls that could subject us to liability or impair our ability to compete in international markets. The U.S. and various foreign governments have imposed controls, export license requirements and restrictions on the import or export of certain products, technologies and software. We must export our products in compliance with U.S. export controls, including the Commerce Department’s Export Administration Regulations and various economic and trade sanctions established by the Treasury Department’s Office of Foreign Assets Controls. We may not always be successful in obtaining necessary export licenses, and our failure to obtain required import or export approval for our products or limitations on our ability to export or sell our products imposed by these laws may harm our international and domestic sales and adversely affect our revenue. Noncompliance with these laws could have negative consequences, including government investigations, penalties and reputational harm. 30 Changes in our products or changes in export, import and economic s anctions laws and regulations may delay our introduction of new products in international markets, prevent our customers from deploying our products internationally or, in some cases, prevent the export or import of our products to or from certain countrie s altogether. While we are not aware of any current or proposed export or import regulations that will materially restrict our ability to sell our products, any change in export or import regulations or legislation, shift or change in enforcement, or chang e in the countries, persons or technologies targeted by these regulations, could result in decreased use of our products by, or in our decreased ability to export or sell our products to, existing or potential customers with international operations. In su ch event, our business and results of operations could be adversely affected. Political unrest, as well as changes in the political, social, business or economic conditions in Thailand, could harm our business, financial condition and operating results. We post-process many of our IC wafers, including testing, dicing and other wafer operations, using subcontractors in Bangkok, Thailand. Deterioration in the political, social, business and economic conditions in Thailand could have a material effect on our business. Thailand has experienced ongoing political and social upheaval over the past two decades, such as in May 2014 when the Royal Thai Army staged a military coup, banned demonstrations and enforced monitoring of civilian activities. In August 2014, Thailand’s national assembly appointed the coup leader as prime minister. Thailand may also experience political unrest stemming from the results of its August 2016 constitutional referendum, as well as the death of its king in October 2016. We do not know what direction the political situation may take or if subsequent issues will affect us. Any changes to tax regimes, laws, exchange controls or political action in Thailand may harm our business, financial condition and operating results. Instability in Thailand could prevent wafer shipments from entering or leaving the country and disrupt our ability to test or post-process wafers in Thailand. In such an event, we could be forced to transfer our testing and dicing activities to more stable, and potentially more costly, regions and find alternative sources for testing and dicing, which could harm our business, financial condition and operating results. Intellectual property licensing from or to others, including competitors, may subject us to requirements or limitations that could adversely affect our business and prospects. We have intellectual property license agreements that give us access to certain patents and intellectual property of others. We have not licensed our patents or intellectual property to others except as necessary for our customers to practice their business using our products and as required pursuant to agreements we have entered into in connection with our participation in the development of GS1 EPCglobal protocols and International Standards Organization, or ISO, standards. In the course of our participation in the development of GS1 EPCglobal protocols, including UHF Gen2, UHF Gen2 V2, tag data standards, or TDS, low-level reader protocol, or LLRP, and others, we have agreed to license on a royalty-free basis those of our patents that are necessarily infringed by the practice of these protocols to other GS1 EPCglobal members, subject to reciprocal royalty-free rights from those other members. Because it may not be clear whether a member’s intellectual property is necessary or optional to the practice of a protocol, disputes could arise among members, resulting in our inability to receive a license on royalty-free terms. Further, some GS1 EPCglobal members declined to provide licenses to some of their intellectual property under royalty-free terms, instead choosing reasonable and non-discriminatory, or RAND, terms. Disputes or confusion may arise about whether we may invoke our necessary intellectual property if these members choose to assert their RAND intellectual property, potentially causing or at least complicating any ensuing litigation and harming our business, financial condition and operating results. In the course of our participation in the development of certain ISO standards we have agreed to grant to all users worldwide a license to those of our patents that are necessarily infringed by the practice of those standards, including at frequencies other than UHF, on RAND terms, again subject to reciprocity. As a result, we are not always able to limit to whom and, to a certain extent, on what terms we license our technologies, and our control over and our ability to generate licensing revenue from some of our technologies may be limited. We may choose to license our patents or intellectual property to others in the future. We cannot guarantee that any patents and technology that we provide in such future licenses will not be used to compete against us. 31 We rely on third-party license agreements; impairment of those agreements may cause pr oduction or shipment delays that could harm our business. We have licensing agreements with other entities for patents, software and technology used in our manufacturing operations and products. For example, we license tools from design-automation software vendors to design our silicon products. Third-party licenses for patents, software and other technology important to our business may not continue to be available on commercially reasonable terms, if at all. Loss of any such licenses could cause significant manufacturing interruptions, delays or reductions in product shipments until we can develop, license, integrate, and deploy alternative technologies, if even possible, which would materially harm our business and operating results. Our use of open-source software may expose us to additional risks and harm our intellectual property. Our products, processes and technology sometimes use or incorporate software that is subject to an open-source license. Open-source software is typically freely accessible, usable and modifiable, and is made available to the general public on an “as-is” basis under the terms of a non-negotiable license. Use and distribution of open-source software may entail greater risks than use of third-party commercial software. Certain open-source software licenses require a user who intends to distribute the open-source software as a component of the user’s software to disclose publicly part or all of the user’s source code. In addition, certain open-source software licenses require the user of such software to make derivative works of the open-source code available to others at low or no cost. Consequently, open-source licensing can subject our previously proprietary software to open-source licensing terms, which could enable our competitors to create similar offerings with lower development effort and time and ultimately could result in a loss of sales. In addition, open-source licensors generally do not provide warranties or other contractual protections regarding infringement claims or the quality of their code, opening us to business risks that could materially harm our operating results. We may face claims alleging noncompliance with open-source license terms or infringement or misappropriation of proprietary software. These claims could result in litigation, require us to purchase a costly license, or require us to devote research and development resources to change our software, any of which would have a negative effect on our business and operating results. Few courts have interpreted open-source licenses, and these licenses could be construed in a way that could impose unanticipated conditions or restrictions on our ability to commercialize our offerings. In addition, if there are changes in the licensing terms for the open-source software we use, we may be forced to re-engineer our solutions, incur additional costs or discontinue sale of our offerings. We cannot guarantee that we have incorporated all open-source software in our software in a manner that is consistent with our current policies and procedures, or in a manner that will not subject us to liability. Privacy and security concerns relating to RAIN could damage our reputation and deter current or potential customers from using our products. Privacy advocates and others have raised and may continue raising concerns about RAIN compromising consumer privacy or facilitating theft. These concerns include unauthorized parties collecting personally identifiable information, tracking consumers, stealing identities or causing other privacy-related issues. Consumers may be subject to unauthorized readers or gateways surreptitiously identifying and tracking their RAIN tags to gain information a consumer considers private, even if the consumer employs protective measures. Retailers may inadvertently or perhaps even intentionally read consumers’ tags to gain information, such as shopping behavior, that may be illegal to collect, or if not illegal, may be considered intrusive by consumers. Unauthorized readers or gateways could gain access to sensitive information stored in tags despite measures designed to thwart such unauthorized access. For example, criminals seeking to divert or steal high- value pharmaceutical products could seek to identify these products by looking for tags with Electronic Product Codes, or EPCs, corresponding to these products. If such concerns increase, or if actual malicious or inadvertent breaches of privacy or theft occur, then our reputation could be damaged, our business and prospects may suffer, and we could incur significant liability. 32 In addition to concerns over privacy or theft, it may be possible for those with malicious intent to misuse RAIN in ways that actually facilitate theft or damage the public trust, such as by changing the EPC on a narcotic to misrepr esent it as an over-the-counter product. It may even be possible to embed computer viruses or other malicious code into endpoint ICs so that by reading endpoint IC memory, the malicious code can be inserted into end-user systems. If a breach occurs, our cu stomers could be the target of regulatory actions or private lawsuits. In such cases, a customer might allege that our products did not function as promised and may sue us for breach of contract, breach of warranty, negligence or another cause of action. A dditionally, if our customers’ security measures are breached, even if through means beyond our control, our reputation may be damaged, we may be subject to litigation and our business and prospects could suffer. Moreover, concerns about security and priva cy risks, even if unfounded, could damage our reputation and operating results and could delay the development of the overall RAIN industry. Security breaches could expose us to litigation and possible liability. Even if our products meet new standards or regulations, if our security measures are breached as a result of third-party action, our error or criminal act or otherwise, and, as a result, someone obtains unauthorized access to customer or end-user data, our reputation could be damaged, our business and prospects may suffer, and we could incur significant liability. Government regulations and guidelines relating to consumer privacy may adversely impact adoption of our products, require us to make design changes or constrain our ability to implement new and desired product features. Our customers are subject to laws and regulations related to collecting, storing, transmitting and using personal information, as well as additional laws and regulations that address privacy and security issues related to radiofrequency identification, or RFID. For example, some U.S. states have enacted statutes specifically governing the use of RFID, including prohibitions on mandatory implantation of an RFID IC, unauthorized skimming of information from ID cards and documents, unauthorized personnel tracking using RFID and improper use of RFID tags in drivers’ licenses or on vehicles. Because RAIN uses RFID technology, we believe these statutes and regulation apply to RAIN systems. The European Commission, or EC, has issued guidance to address privacy concerns about RFID. In May 2009, the EC issued a recommendation that retail companies in the EU inform their customers when RFID tags are either on or embedded within products. In April 2011, the EC signed a voluntary agreement with private and public stakeholders to develop privacy guidelines for companies using RFID in the EU. The agreement requires companies to conduct privacy impact assessments of new RFID applications and to take measures to address risks identified by the assessment before the RFID application is deployed. While compliance with the guidelines is voluntary, our customers that do business in the EU may have a preference for products that comply with the guidelines. If our RAIN products do not provide the necessary functionality to allow customers to comply with the guidelines then our business may suffer. The data security and privacy legislative and regulatory landscape in the United States and EU, and other foreign jurisdictions is evolving, and changes in laws and regulations may adversely impact our business, including our ability to develop future products. If we fail to develop products that implement end-user privacy requirements then end users may choose not to use our products in certain applications, which would harm our business, operating results and financial condition. Although the Gen2 V2 protocol described below includes features for addressing consumer privacy and authenticating a tag, a third party may still breach these features, including as implemented in our products, in which case our reputation could be damaged and our business and prospects may suffer. 33 Alternative technologies or standards, or changes in existing technologies or standards, may adversely affect RAIN market growth. Technology developments may affect our business in ways we cannot anticipate. Breakthroughs in legacy RFID technologies or markets, including those using low frequency or high frequency technology, could adversely affect RAIN market growth generally and demand for our products in particular. For example, NFC technology, which today addresses a different market than RAIN, could, with breakthrough innovations, compete with RAIN in item tagging. Likewise, new technologies such as organic transistors may allow lower-cost ICs than our current silicon-based technology allows. These competing technologies could use intellectual property that is either not royalty free or to which we do not have access. If we are unable to innovate using new or enhanced technologies or processes, or are slow to react to changes in existing technologies or in the market, or have difficulty competing with advances in new or legacy technologies, then our development of new or enhanced products could be materially impacted and potentially result in product obsolescence, decreased revenue and reduced market share. To encourage widespread RAIN market adoption, we have participated in the development of industry standards, and we have designed our products to comply with these standards. In 2013, GS1 EPCglobal ratified “UHF Gen2 Version 2” or simply “Gen2 V2,” a new version of the protocol that underlies RAIN communications. In the future, we could lose our position in GS1 EPCglobal or we could lose our project-editorship role for UHF Gen2. If one of our competitors introduces a Gen2 V2 product that gains market adoption before we do, we could lose market share and face difficulty selling our products. The introduction of new industry standards, or changes to existing industry standards, could make our products incompatible with the new or changed standards and could cause us to incur substantial development costs to adapt to these new or changed standards, particularly if they were to achieve, or be perceived as likely to achieve, greater penetration in the marketplace. If Gen2 V2 diverges significantly from our or the RAIN market’s needs then our products may likewise fail to keep pace with the market, our competitors’ products and end-user requirements, in which case end users could delay RAIN adoption. Moreover, the adoption or expected adoption of new or changed standards could slow the sale of our existing products before products based on the new or changed standards become available. New industry standards or changes to existing standards could also limit our ability to implement new features in our products if those features do not meet the new or changed standards. The lost opportunities as well as time and expense required for us to develop new products or change our existing products to comply with new or changed standards could be substantial, and we cannot assure you that we could successfully develop products that comply with new or changed standards. If we are not successful in complying with any new or changed industry standards, then we could lose market share, causing our business to suffer. We are a founding member of the RAIN Alliance. Our chief executive officer is presently an Alliance Director and was previously the Alliance Chairman. Board membership is an elected position that we could lose in future elections. It provides industry stature and attendant benefits but is not without risk. If the RAIN market falters, or if the RAIN Alliance falters, then we could be blamed, our reputation and industry position could be impacted, and our business could suffer. Compliance with, and changes in, government spectrum regulations could adversely affect our ability to sell products and impair our operating results. Government radio regulations require that our readers and gateways be certified for spectral compliance in jurisdictions where they are sold or operated. Our readers and gateways are collectively certified for use in more than 40 countries worldwide, including the United States, Canada, Mexico, China, Japan, South Korea and each country in the EU. If one of our reader or gateway products is found to be noncompliant despite having such certification then we could be required to modify field-deployed readers or gateways to regain certification and could spend significant resources as well as miss sales opportunities in the process. Our revenue could decline, adversely affecting our operating results, financial condition, business and prospects. Additionally, government regulations may change, requiring us to redesign our products to the new regulations or constraining our ability to implement new and desired features into our products, thereby causing us to incur significant expenses or forego opportunities to improve our products, potentially delaying time-to-market, adversely affecting our operating results, financial condition, business and prospects. 34 Our products may cannibalize revenue from each other, which could harm our business. Sales of some of our products enable our channel partners to develop their own products that compete with other of our products. For example, sales of our reader ICs allow technology companies to build and sell readers and gateways that compete with our products. Similarly, sales of our readers allow our channel partners to build and sell products that compete with our xPortal, xArray and xSpan. We even see cannibalization within our own product line—for example, our xSpan sometimes competes with our xPortal. In the future, we may see one product line expand at the expense of another, or we may be asked by channel partners to disadvantage or divest a product line. We cannot predict whether we can manage such conflicts in the future, or retain channel partners despite conflicts. Any of the foregoing could have a material adverse effect on our business, financial condition and operating results. Acquisitions could result in operating difficulties, dilution and other harmful consequences. We have evaluated, and expect to continue evaluating, potential strategic transactions, and we may pursue one or more transactions, including acquisitions. We have limited experience executing acquisitions. Any transaction could be material to our financial condition and operating results. Integrating an acquired company, business or technology may create unforeseen operating difficulties and expenditures. Acquisition-related risks include: • • • • • • • • • • diverting management time and focus from operating our business to acquisition integration; difficulties integrating acquired products into our strategy and product plans; customers switching from us to new suppliers because of the acquisition; inability to retain employees from the business we acquire; challenges associated with integrating employees from the acquired company into our organization; difficulties integrating accounting, management information, human resource and other administrative systems to permit effective management of the business we acquire; potential requirements for remediating controls, procedures and policies appropriate for a public company in the acquired business that prior to the acquisition lacked these controls, procedures and policies; potential liability for past or present environmental, hazardous substance, or contamination concerns associated with the acquired business or its predecessors; possible write-offs or impairment charges resulting from the acquisition; and unanticipated or unknown liabilities relating to the acquired business. Foreign acquisitions involve additional risks beyond those above, including related to integrating operations across different cultures and languages, currency risks and the economic, political and regulatory risks associated with other countries. Also, the anticipated benefit of any acquisition, domestic or foreign, may not materialize. Future acquisitions or dispositions could result in potentially dilutive issuances of our equity securities, debt incurrence, contingent liabilities or amortization expenses or goodwill write-offs, any of which could harm our financial condition. Future acquisitions may require us to obtain additional equity or debt financing, which may not be available on favorable terms or at all. Our business could be adversely affected if one or more members of our executive management team departed. Our success depends, in large part, on the continued contributions of our executive management team including Chris Diorio, Ph.D., our chief executive officer; Eric Brodersen, our chief operating officer; and Evan Fein, our chief financial officer. None of our executive management team is bound by employment contracts to remain with us for a specified period. The loss of any member of our executive management team could harm our ability to implement our business strategy and respond to the rapidly changing market conditions in which we operate. 35 If we are una ble to attract, train and retain qualified personnel, especially technical, sales and marketing personnel, then we may not be able to effectively execute our business strategy. Our success depends on our ability to attract, motivate and retain qualified personnel. Our technical personnel, the source of our technical and product innovations, and our sales and marketing personnel that drive our go-to-market initiatives are especially important. There is no guarantee we can attract and retain such personnel as we continue to pursue our business strategy. The availability of, and competition for, qualified personnel in the Seattle area, where we are headquartered, constrains our ability to attract qualified personnel. The loss of the services of one or more of our key employees, or our inability to attract, retain and motivate qualified personnel could have a material adverse effect on our business, financial condition and operating results. Pricing and other provisions in our customer agreements could adversely affect our operating results. In the ordinary course of business we enter into agreements containing pricing terms; in some instances the terms, whether advertently or inadvertently, may adversely affect our operating results and gross margins. For example, some contracts specify future reader, gateway or IC pricing, or contain most-favored customer pricing for certain products. As another example, some agreements contain exclusivity terms that prevent us from pursuing certain business with other customers during the exclusivity period. Further, reducing prices or offering other favorable terms to one customer could adversely affect our ability to negotiate favorable terms with other customers. We may decide for competitive or strategic reasons to enter into similar types of agreements in the future, and such agreements could impair our operating results. We and our suppliers are subject to environmental laws and regulations that could impose substantial costs on us and may adversely affect our business, operating results and financial condition. Some of our facilities, including those devoted to research and development, are regulated under federal, state, local, foreign and international environmental laws. Those laws govern pollutant discharge into air and water; managing, disposing, handling, labeling, and exposure to hazardous substances/wastes; and contaminated site cleanup. We could incur costs, fines and civil or criminal sanctions; third-party property damage or personal-injury claims; or could be required to pay substantial investigation or remediation costs, if we were to violate or become liable under environmental laws. Liability under certain environmental laws can be joint and several and without regard to comparative fault. In addition, some of our products contain hazardous substances and are subject to requirements that regulate their content, such as the EU’s Restriction of Hazardous Substances Directive, or RoHS, and analogous regulations elsewhere. Although we design our products to be compliant with environmental regulations and require our third-party contractors to comply, we cannot guarantee that we or our products will always be in compliance with these requirements. Environmental laws also tend to become more stringent over time, and we cannot predict the ultimate costs under environmental laws or the timing of these costs. Failure to comply with these and other environmental laws could result in fines, penalties and decreased revenue, which could adversely affect our operating results. If our third-party contractors fail to operate in compliance with environmental requirements, properly dispose of wastes associated with our products, or comply with requirements governing the hazardous-substance content of our products, we could be held liable or suffer reputational harm. We may not sustain or effectively manage our growth. We have experienced significant revenue growth in a short period of time. We may not experience similar growth rates in future periods. You should not rely on our operating results for any prior periods as an indication of our future operating performance. If we are unable to maintain adequate revenue growth then our financial results could suffer and our stock price would decline. To manage our growth and the responsibilities of being a public company, we believe we must effectively: • • recruit, hire, train and manage qualified engineers for our research and development activities; add sales and marketing personnel and expand our customer-support offices; 36 • • • implement and impro ve administrative, financial and operational systems, procedures and controls; integrate and train new employees quickly and effectively; and coordinate growth among our executive, engineering, finance, marketing, sales, operations and customer-support organizations. All the above activities add to our organizational complexity and increase our operating expenses. We may have insufficient management capabilities or resources to manage our growth and business effectively. As a consequence of our small management team we may be unable to pursue all commercial opportunities. Accordingly, we may require significant additional resources as we increase the complexity and scale of our business operations. We cannot assure you that we will have adequate resources when we need them or that we will have sufficient capital to fund our resource needs. If we are unable to manage our growth effectively, we may not be able to exploit market opportunities or develop new products, and we may fail to satisfy customer requirements, maintain product quality, execute our business plan or respond to competitive pressures. Our management has limited public-company experience. We are subject to additional regulatory compliance requirements, including Section 404 of the Sarbanes-Oxley Act of 2002. If we fail to maintain an effective system of internal controls then we may not be able to accurately report our consolidated financial results or prevent fraud. In the course of preparing our consolidated financial statements, we previously identified a material weakness in our internal control over financial reporting. We have only very recently begun operating as a public company. Most of our management team, including our chief executive officer and chief financial officer, have never managed a publicly traded company prior to our initial public offering and have little experience complying with the increasingly complex and changing laws pertaining to public companies. Our entire management team as well as other company personnel will need to devote substantial time to compliance, and may not effectively or efficiently manage our maturation as a public company. We have incurred and will continue to incur significant legal, accounting and other expenses that we did not incur as a private company. We expect rules and regulations such as the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, to increase our legal and finance compliance time and costs, and also to increase the time and costs of other activities. For example, Section 404 of the Sarbanes-Oxley Act requires that management report on, and our independent registered public accounting firm attest to, the effectiveness of our internal control over financial reporting. Effective internal controls are necessary for us to provide reliable financial reports and prevent fraud. Section 404 compliance will divert resources and take significant time and effort to complete. We, management, will be required to report on the effectiveness of our internal control over financial reporting for the year ending December 31, 2017. We may be unable to successfully complete the procedures and certification and attestation requirements of Section 404 by the time we are required to do so. In addition, the Sarbanes-Oxley Act requirements may be modified, supplemented or amended from time to time. Implementing the changes may take significant time and may require additional employee compliance training. We may discover internal controls that need improvement. Our or our independent registered public accounting firm’s discovery of a material weakness, even if quickly remedied, could reduce the market’s confidence in our financial statements and harm our stock price. Any inability to provide reliable financial reports or prevent fraud could harm our business. 37 We may be unable to effectively implement, or effectively implement in a timely manner, the necessary controls and employee t raining to ensure continued compliance with the Sarbanes-Oxley Act and other regulatory and reporting requirements. Our growth will challenge our ability to maintain the internal control and disclosure standards applicable to public companies. If we fail t o successfully complete the procedures and certification and attestation requirements of Section 404, or if in the future our chief executive officer, chief financial officer or independent registered public accounting firm determines that our internal con trol over financial reporting is not effective as defined under Section 404, we could be subject to sanctions or investigations by the Securities and Exchange Commission, or SEC, or by other regulatory authorities. Investor perceptions of our company may s uffer, likely causing a decline in our stock’s market price. We cannot assure you that we will be able to fully comply with the requirements of the Sarbanes-Oxley Act or that management or our independent registered public accounting firm will conclude tha t our internal controls are effective in future periods. Irrespective of compliance with Section 404, any failure of our internal controls could have a material adverse effect on our stated operating results and harm our reputation. In the course of preparing our consolidated financial statements in prior years, we, in conjunction with our independent registered public accounting firm, identified an error in the accounting treatment for the recapitalization of our company in 2012 and the impact of the recapitalization on earnings per share that resulted in the restatement of our previously issued financial statements for the years ended December 31, 2012 and 2013. In 2015, we, in conjunction with our independent registered public accounting firm, identified an error related to the cash flow statement presentation of lease incentives in our consolidated interim financial statements for the nine months ended September 30, 2015. Also, in 2016, we identified that we inadvertently did not reflect the correction of the identified error related to the cash flow statement presentation of lease incentive in our consolidated interim financial statements for the nine months ended September 30, 2015 on the statement of cash flows included in our quarterly report on Form 10-Q filed with the SEC on November 7, 2016. These financial statement errors, combined with other identified control deficiencies, were considered to indicate a material weakness in our internal control over financial reporting related to the accounting and financial statement disclosure over complex accounting matters. A material weakness is a deficiency, or combination of control deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim consolidated financial statements will not be prevented or detected on a timely basis. We have taken and continue to take steps to remediate the material weakness, including increasing the depth and experience within our accounting and finance organization, as well as designing and implementing improved processes and internal controls. As of December 31, 2016, this material weakness had not been remediated. Our remediation of this material weakness in future periods may not be effective or prevent future material weaknesses or significant deficiencies in our internal control over financial reporting. If we fail to hire additional finance personnel or fail to strengthen our financial reporting systems and infrastructure then we may be unable to timely and accurately report our financial results or comply with the requirements of being a public company, including compliance with the Sarbanes-Oxley Act and SEC reporting requirements, which in turn could significantly harm our reputation and our business. We intend to hire personnel with financial reporting and Sarbanes-Oxley Act compliance expertise. Any impact to our plan such as an inability to hire, a delay in hiring, or a delay in training such personnel could adversely impact our ability to timely and accurately prepare our financial statements. Further, our ability to retain employees with the requisite experience could adversely affect our financial statements because new employees require time and training to learn our business and operating procedures. If our finance and accounting organization is unable for any reason to meet the increased demands of being a public company then the quality and timeliness of our financial reporting may suffer, which could result in material weaknesses in our internal controls. The consequences of inaccuracies or delays in our reported financial statements could cause the trading price of our common stock to decline and could harm our business, operating results and financial condition. 38 We may need to raise additional capital which may not be available on favorable terms, if at all, causing dilution to stockholders, restricting our operations or adversely affecting our ability to operate our business. In the course of running our business we may need to raise capital, diluting our stockholders. If our need is due to unforeseen circumstances or material expenditures or if our operating results are worse than expected then we cannot be certain that we will be able to obtain additional financing on favorable terms, if at all, and these additional financings could cause additional dilution to our stockholders. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, expending capital, or declaring dividends, or which impose financial covenants on us that limit our ability to achieve our business objectives. If we need but cannot raise additional capital on acceptable terms then we may not be able to meet our business objectives, our stock price may fall, and you may lose some or all of your investment. Our debt obligations contain restrictions that impact our business and expose us to risks that could adversely affect our liquidity and financial condition. We have a loan and security agreement, or senior credit facility, with Silicon Valley Bank. The senior credit facility provides for (1) a $10.5 million aggregate principal amount of outstanding term borrowings, (2) revolver borrowings up to the lesser of $15.0 million and a borrowing base tied to the amount of our eligible accounts receivable and inventory, (3) a $5.0 million sublimit under the revolver for the issuance of standby letters of credit and (4) an equipment term- loan facility of up to $2.0 million. At December 31, 2016, we had $10.5 million term loan borrowings outstanding, no revolver borrowings outstanding and $1.9 million equipment loan borrowings outstanding. Our senior credit facility contains customary covenants, which limit our and our subsidiaries’ ability to, among other things: • • • • • • • incur additional indebtedness or guarantee indebtedness of others; create liens on our assets; enter into mergers or consolidations; dispose of assets; pay dividends and make other distributions on our capital stock, and redeem and repurchase our capital stock; make investments, including acquisitions; and enter into transactions with affiliates. Our senior credit facility also includes customary affirmative covenants, tangible net worth and liquidity ratio covenants. The senior credit facility contains customary events of default, subject to customary cure periods for certain defaults, that include, among others, non- payment defaults, covenant defaults, material judgment defaults, bankruptcy and insolvency defaults, cross-defaults to certain other material indebtedness, a material adverse change default and inaccuracy of representations and warranties. If we experience a decline in cash flow due to any of the factors described in this “Risk Factors” section or otherwise, we could have difficulty paying interest and principal amounts due on our indebtedness and meeting the financial covenants set forth in our senior credit facility. If we are unable to generate sufficient cash flow or otherwise obtain the funds necessary to make required payments under our senior credit facility, or if we fail to comply with the requirements of our indebtedness, we could default under our senior credit facility. Any such default that is not cured or waived could result in the acceleration of the obligations under the senior credit facility, an increase in the applicable interest rate under the senior credit facility, and would permit our lender to exercise remedies with respect to all of the collateral that is securing the senior credit facility, including substantially all of our assets, other than intellectual property. Any such default could have a material adverse effect on our liquidity and financial condition. 39 Even if we comply with all of the applicable covenants, the restrictions on the conduct of our business could adversely affect our business by, among other things, limiting our ability to take advantage of financings, mergers, acquisitions and o ther corporate opportunities that may be beneficial to the business. A breach of our security systems could have a material adverse effect on our business. We use security systems to maintain our facility’s physical security and to protect our proprietary and confidential information, including that of our customers, suppliers and employees. Accidental or willful security breaches or other unauthorized access to our facilities or information systems, or viruses, loggers, or other malfeasant code in our data or software, could compromise this information. The consequences of such loss and possible misuse of our proprietary and confidential information could include, among other things, unfavorable publicity, damage to our reputation, difficulty marketing our products, customer allegations of breach-of- contract, litigation by affected parties and possible financial liabilities for damages, any of which could have a material adverse effect on our business, financial condition, reputation and relationships with customers and partners. We also rely on third-party providers of corporate infrastructure services relating to, among other things, human resources, electronic communication services and some financial functions, and we are therefore dependent on the security systems of these providers. Any security breaches or other unauthorized access to our service-providers’ systems or viruses, loggers, or other malfeasant code in their data or software could expose us to information loss and misappropriation of confidential information. Because the techniques used to obtain unauthorized access to or sabotage security systems change frequently and are often not recognized until after an attack, we may be unable to anticipate the techniques or implement adequate preventative measures, thereby exposing us to material adverse effect on our business, operations and financial condition. Our operations could be disrupted by natural disasters. An earthquake, fire, flood or other natural or manmade disaster could disable our facilities, disrupt operations, or cause catastrophic losses. We have facilities in areas with a known history of seismic activity, such as our headquarters in Seattle, Washington. We also have facilities in areas with a known history of flooding, such as our office in Shanghai, China. We have a wafer testing and dicing subcontractor in Thailand, a region with a known, and quite recent, history of flooding. A loss at or of any of these or other of our or our suppliers’ facilities could disrupt operations, delay production and shipments, reduce revenue and engender potentially large expenses to repair or replace the facility. As a specific example, in 2011 and 2012 floods in Thailand disrupted our subcontractor’s facility for approximately six months. During that time, we relied on a secondary subcontractor that had longer lead times for, and decreased yield of, our endpoint IC wafers. We do not carry insurance policies that cover potential losses caused by earthquakes, floods or other disasters. Our ability to use net operating losses to offset future taxable income may be limited. As of December 31, 2016, we had federal net operating loss carryforwards, or NOLs, of $100.0 million and federal research and experimentation credit carryforwards of $8.5 million which we may use to reduce future taxable income or offset income taxes due. The NOLs start expiring in 2023. The credit carryforwards start expiring in 2020. Insufficient future taxable income will adversely affect our ability to utilize these NOLs and credit carryforwards. In addition, under Sections 382 and 383 of the U.S. Internal Revenue Code, or the Code, a corporation that experiences a more-than 50% ownership change over a three-year testing period is limited in its ability to use its pre-change NOLs and other tax assets to offset future taxable income or income taxes due. Our existing NOLs and credit carryforwards may be subject to limitations arising from previous ownership changes; if we undergo an ownership change then our ability to use our NOLs and credit carryforwards could be further limited by Sections 382 and 383 of the Code. Future changes in our stock ownership, the causes of which may be outside our control, could result in an ownership change under Sections 382 and 383 of the Code. Our NOLs may also be impaired under state law. As a result of these limitations, we may not be able to utilize a material portion of, or possibly any of, the NOLs and credit carryforwards. 40 We could be subject to additional income tax liabilities. We are subject to income taxes in the United States and certain foreign jurisdictions. We use significant judgment in evaluating our worldwide income-tax provision. During the ordinary course of business, we conduct many transactions for which the ultimate tax determination is uncertain. For example, our effective tax rates could be adversely affected by earnings being lower than anticipated in countries where we have lower statutory rates and higher than anticipated in countries where we have higher statutory rates, by changes in currency exchange rates, by changes in the valuation of our deferred tax assets and liabilities or by changes in the relevant tax, accounting and other laws, regulations, principles and interpretations. We are subject to audit in various jurisdictions, and such jurisdictions may assess additional income tax against us. Although we believe our tax estimates are reasonable, the final determination of tax audits and any related litigation could be materially different from our historical income-tax provisions and accruals. The results of an audit or litigation could have a material effect on our operating results or cash flows in the period or periods for which that determination is made. Taxing authorities may successfully assert that we should have collected or in the future should collect sales and use, value-added or similar taxes, and we could be subject to liability with respect to past or future sales, which could adversely affect our operating results. We do not collect sales and use, value-added or similar taxes in all jurisdictions in which we have sales, based on our belief that such taxes are either not applicable or an exemption from such taxes applies. Sales and use, value- added and similar tax laws and rates vary greatly by jurisdiction. Certain jurisdictions in which we do not collect such taxes may assert that such taxes are applicable, which could result in tax assessments, penalties and interest, and we may be required to collect such taxes in the future, including as a result of a change in law. Such tax assessments, penalties and interest or future requirements may adversely affect our operating results. We are subject to SEC rules regarding the use and disclosure of conflict minerals, which we expect will increase our operating and compliance costs and could potentially harm our reputation, causing a decline in our stock price. We are subject to the requirements under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, that will require us to diligence, disclose and report whether our solutions contain conflict minerals. The rule requires us to submit forms and reports to the SEC by May 31, 2019 and annually thereafter to disclose our determinations and due-diligence measures regarding conflict minerals. Although we do not directly purchase conflict minerals, tracing the minerals our suppliers use back to country of origin is a complex task that requires us to, among other things, survey our supply chain to understand what programs our suppliers have for tracing the source of minerals used in products supplied to us and ensure these suppliers have performed reasonable due diligence. We have not determined how many or, if any, of our suppliers use conflict minerals. In addition to the increased administrative expense required to comply with these requirements, some of our customers are also subject to this rule, and we have been and will continue to be asked as part of their supply chain to comply with their requirements as part of their compliance with the rule. Moreover, we may face a limited pool of suppliers who can provide “conflict-free” products, and we may not be able to obtain conflict-free products or supplies in sufficient quantities or at competitive prices for our operations. We may be required to disclose our products as not being “conflict free,” which could adversely affect our reputation and may harm relationships with business partners and customers, and our stock price could suffer as a result. 41 Risks Relating to Ownership of Our Common Stock The market price of our common stock has been and will likely continue to be volatile, and the value of your investment could decline significantly. There was no public market for our common stock prior to our initial public offering. Since July 2016, when we sold shares of our common stock in our initial public offering at a price of $14.00 per share, our stock price has ranged from $16.36 to $41.61 through February 28, 2017. Securities of companies similar to ours experience significant price and volume fluctuations. The following factors, in addition to other risks described in this report, may have a significant effect on our common stock price: • • • • • • • • • • • • • • • • • • • • price and volume fluctuations in the overall stock market from time to time; changes in operating performance, stock market valuations, and volatility in the market prices of other technology companies generally, or those in our industry in particular; actual or anticipated quarterly variations in our results of operations or those of our competitors; actual or anticipated changes in our growth rate relative to our competitors; delays in end-user deployments of RAIN systems; announcements by us or our competitors of acquisitions, new products, significant contracts, commercial relationships or capital commitments; supply interruptions; developments with respect to intellectual property rights; our ability to develop and market new and enhanced products on a timely basis; commencement of, or our involvement in, litigation; changes in our board of directors or management; changes in governmental regulations or in the status of our regulatory approvals; unstable regional political and economic conditions, such as those caused by the U.S. presidential election and the U.K. referendum to leave the EU; the trading volume of our stock; limited public float; any future sales of our common stock or other securities; failure of financial analysts to maintain coverage of us, changes in financial estimates by any analysts who follow our company, or our failure to meet these estimates or the expectations of investors; fluctuations in the values of companies perceived by investors to be comparable to us; the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections; and general economic conditions and slow or negative growth of related markets. In addition, the stock market in general, and the market for technology companies in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. Broad market and industry factors may seriously affect our stock price, regardless of our actual operating performance. In addition, in the past, securities class action litigation has often been instituted against companies whose stock prices have declined, especially following periods of volatility in the overall market. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’s attention and resources. 42 If securities or industry analysts do not publish research reports about our business, or if they issue an adverse opinion about our business, our stock price and trading volume could decline. The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. If one or more of the analysts who cover us issues an adverse opinion about our company, our stock price would likely decline. If one or more of these analysts ceases coverage of us or fails to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline. Future sales of our common stock in the public market could cause our stock price to fall. Sales of a substantial number of shares of our common stock into the public market, particularly sales by our directors, executive officers, and principal stockholders, or the perception that these sales might occur, could cause the market price of our common stock to decline. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. In addition, in the future, we may issue additional shares of common stock or other equity or debt securities convertible into common stock in connection with a financing, acquisition, litigation settlement, employee arrangement or otherwise. Any such issuance could result in substantial dilution to our existing stockholders and could cause our stock price to decline. Our principal stockholders and management own a significant percentage of our stock and are able to exercise significant influence over matters subject to stockholder approval. As of February 28, 2017, our executive officers, directors and principal stockholders, together with their respective affiliates, beneficially owned approximately 35.3% of our capital stock. As a result, our executive officers, directors and principal stockholders, if acting together, may be able to significantly influence, in their capacity as stockholders, matters requiring approval by our stockholders, including the election of directors and the approval of mergers, acquisitions or other extraordinary transactions. They may also have interests that differ from yours and may vote in a way with which you disagree and which may be adverse to your interests. This concentration of ownership could have the effect of delaying or preventing a change in our control or otherwise discouraging a potential acquirer from attempting to obtain control of us, which in turn could have a material adverse effect on our stock price and may prevent attempts by our stockholders to replace or remove our board of directors or management. An active trading market for our common stock may not be sustained. Prior to our initial public offering, there was no public market for our common stock. Although our common stock is listed on The NASDAQ Global Select Market, an active trading market for our shares may not be sustained. Anti-takeover provisions in our charter documents and under Delaware or Washington law could make an acquisition of us difficult, limit attempts by our stockholders to replace or remove our current management and limit our stock price. Provisions of our certificate of incorporation and bylaws may delay or discourage transactions involving an actual or potential change in our control or change in our management, including transactions in which stockholders might otherwise receive a premium for their shares, or transactions that our stockholders might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of our stock. Among other things, our certificate of incorporation and bylaws: • • permit our board of directors to issue up to 5,000,000 shares of preferred stock, with any rights, preferences and privileges as they may designate; provide that the authorized number of directors may be changed only by resolution of the board of directors; 43 • • • • • • • • provide that all vacancies, including newly created directorships, may, except as otherwise required by law, be filled by the affirmative vote of a majority of directors then in offi ce, even if less than a quorum; divide our board of directors into three classes; restrict the forum for certain litigation against us to Delaware; require that any action to be taken by our stockholders must be effected at a duly called annual or special meeting of stockholders and may not be taken by written consent; provide that stockholders seeking to present proposals before a meeting of stockholders or to nominate candidates for election as directors at a meeting of stockholders must provide notice in writing in a timely manner, and also specify requirements as to the form and content of a stockholder’s notice; do not provide for cumulative voting rights (therefore allowing the holders of a plurality of the shares of common stock entitled to vote in any election of directors to elect all of the directors standing for election, if they should so choose); provide that special meetings of our stockholders may be called only by the chairman of the board, our chief executive officer or by the board of directors; and provide that stockholders will be permitted to amend our bylaws only upon receiving at least two-thirds of the total votes entitled to be cast by holders of all outstanding shares then entitled to vote generally in the election of directors, voting together as a single class. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any “interested” stockholder for a period of three years following the date on which the stockholder became an “interested” stockholder. Likewise, because our principal executive offices are located in Washington, the anti-takeover provisions of the Washington Business Corporation Act may apply to us under certain circumstances now or in the future. These provisions prohibit a “target corporation” from engaging in any of a broad range of business combinations with any stockholder constituting an “acquiring person” for a period of five years following the date on which the stockholder became an “acquiring person.” See “Description of Capital Stock.” Our bylaws provide that the Court of Chancery of the State of Delaware is 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 bylaws provide that, unless we otherwise consent in writing, the Court of Chancery of the State of Delaware is the exclusive forum for any derivative action or proceeding brought on our behalf, any action asserting a breach of fiduciary duty, any action asserting a claim against us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws or any action asserting a claim against us that is governed by the internal affairs doctrine. The choice of forum provision may limit stockholders’ ability to bring a claim in a judicial forum 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 bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could adversely affect our business and financial condition. 44 As an emerging growth company within the meaning of the Securities Act, we will utilize certain modified disclosure requirements, and we cannot be certain if these reduced requirements will make our common stock less attractive to investors. We are an emerging growth company, and for as long as we continue to be an emerging growth company, we may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to “emerging growth companies” including: • • • not being required to have our independent registered public accounting firm audit our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act; reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We have in this report utilized, and we plan in filings with the SEC to continue to utilize the modified disclosure requirements available to emerging growth companies. As a result, our stockholders may not have access to certain information they may deem important. In addition, Section 107 of the JOBS Act also provides that an emerging growth company can utilize the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to use this extended transition period under the JOBS Act. As a result, our consolidated financial statements may not be comparable to the financial statements of issuers who are required to comply with the effective dates for new or revised accounting standards that are applicable to public companies, which may make our common stock less attractive to investors. We could remain an “emerging growth company” for up to five years from the date of our initial public offering, or until the earliest of: • • • the last day of the first fiscal year in which our annual gross revenue exceeds $1 billion; the date that we become a “large accelerated filer” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended, or Exchange Act, which would occur if the market value of our common stock that is held by non-affiliates exceeds $700 million as of the last business day of our most recently completed second fiscal quarter; or the date on which we have issued more than $1 billion in non-convertible debt during the preceding three-year period. We have incurred and will continue to incur increased costs by being a public company. We have incurred and will continue to incur significant legal, accounting and other expenses as a public company, including costs associated with public company reporting requirements. We have incurred and will continue to incur costs associated with recently adopted corporate governance requirements, including requirements of the SEC and The NASDAQ Global Select Market. We expect these rules and regulations to increase our legal and financial compliance costs and to make some activities more time-consuming and costly. We also expect these rules and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, we may have more difficulty attracting and retaining qualified individuals to serve on our board of directors or as executive officers. We are currently evaluating and monitoring developments with respect to these rules, and we cannot predict or estimate the additional costs we may incur or the timing of such costs. 45 So long as we remain an “emerging growth company,” we expect to avail ourselves of the exemption from the requirement that our independ ent registered public accounting firm attest to the effectiveness of our internal control over financial reporting under Section 404. When our independent registered public accounting firm is required to undertake an assessment of our internal control over financial reporting, the cost of our compliance with Section 404 will correspondingly increase. Moreover, if we are not able to comply with the requirements of Section 404 applicable to us in a timely manner, or if we or our independent registered public accounting firm identifies deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the market price of our stock could decline and we could be subject to sanctions or investigations by the SEC or other regul atory authorities, which would require additional financial and management resources. Item 1B. Unresolved Staff Comments Not applicable. Item 2. Properties We have various operating leases for office space and equipment. Seattle, Washington In December 2014, we entered into a lease for our corporate headquarters in Seattle. Pursuant to the terms of this lease, we occupy a total of approximately 70,000 square feet as of the date of this report, and we are obligated to make escalating monthly lease payments that began in January 2016 and continue through December 2026. In October 2013, we entered into a lease for additional office space in Seattle that is used for a design laboratory. Pursuant to the terms of the lease, we currently occupy a total of approximately 11,000 square feet, and we are obligated to make escalating monthly lease payments that began in November 2013 and continue through October 2018. Newport Beach, California In August 2013, we entered into a lease for office space in Newport Beach. Pursuant to the terms of the lease, we currently occupy a total of approximately 1,100 square feet, and we are obligated to make escalating monthly lease payments that began in September 2013 and continue through February 2017. Shanghai, China In February 2015, we entered into a lease agreement for office space in Shanghai (as amended from time to time). Pursuant to the terms of the lease, we currently occupy a total of approximately 4,000 square feet, and we are obligated to make escalating monthly lease payments that began in April 2015 and continue through March 2018. Item 3. Legal Proceedings As of the date of this report, we are not a party to any material legal proceedings. In the normal course of business, we may be named as a party to various legal claims, actions and complaints. We cannot predict whether any resulting liability would have a material adverse effect on our financial position, results of operations or cash flows. Item 4. Mine Safety Disclosures Not applicable. 46 Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities Market Information and Holders Our common stock has traded on The Nasdaq Global Select Market under the symbol “PI” since July 21, 2016. The following table sets forth, for each quarterly period indicated, the high and low sales prices per share for our common stock as quoted on The Nasdaq Global Select Market: PART II Year Ended December 31, 2016: Third Quarter Fourth Quarter Holders of Record High Low $ $ 38.43 41.91 16.36 23.55 As of February 28 , 2017, there were 116 holders of record of our common stock. The actual number of stockholders is greater than this number of record holders and includes stockholders who are beneficial owners but whose shares are held in street name by brokers and other nominees. This number of holders of record also does not include stockholders whose shares may be held in trust by other entities. Dividends We have never declared or paid a cash dividend on our common stock and we intend to retain all available funds and any future earnings to fund the development and growth of our business. We therefore do not anticipate paying any cash dividends on our commo n stock in the foreseeable future. In addition, our senior credit facility materially restricts, and future debt instruments may materially restrict, our ability to pay dividends on our common stock. Any future determinations to pay dividends on our common stock would depend on our results of operations, our financial condition and liquidity requirements, restrictions that may be imposed by applicable law or our contracts, and any other factors that our board of directors may consider relevant. Recent Sales of Unregistered Securities and Use of Proceeds from Registered Securities Recent Sales of Unregistered Securities The following list sets forth information regarding all unregistered securities sold by us in 2016. No underwriters were involved in the sales, and the certificates representing the securities sold and issued contain legends restricting transfer of the securities without registration under the Securities Act or an applicable exemption from registration. • • From January 1, 2016 through December 31, 2016, options to purchase 42,513 shares of common stock had been exercised under the 2000 Stock Plan for aggregate consideration of $45,192, at exercise prices ranging from $0.60 to $3.60 per share. From January 1, 2016 through December 31, 2016, the registrant granted options under its 2010 Equity Incentive Plan to purchase an aggregate of 99,073 shares of common stock to employees, consultants and directors, having exercise prices ranging from $8.28 to $8.64 per share. During this period, options to purchase 153,927 shares of common stock had been exercised for aggregate consideration of $554,513, at exercise prices ranging from $0.84 to $10.32 per share. 47 • • From January 1, 2016 through December 31, 2016, the registrant granted options under its 2016 Equity Incentive Plan to purchase an aggregate of 607,815 shares of common stock to employees, consultants and directors, having exercise prices ranging from $21.81 to $25.30 per share. From January 1, 2016 through December 31, 2016, the registrant issued and sold 6,691 shares of Series 2 redeemable convertible preferred stock to accredited investors upon the exercise of warrants at an exercise price of $9.32 per share for aggregate proceeds of $62,375 and issued and sold 179,017 shares of common stock to accredited investors upon net exercise of warrants at exercise prices of $2.52 and $9.32 per share. The offers, sales and issuances of the securities described above were exempt from registration under the Securities Act under either (1) Rule 701 in that the transactions were under compensatory benefit plans and contracts relating to compensation as provided under Rule 701, (2) Section 4(a)(2) of the Securities Act as transactions by an issuer not involving any public offering or (3) Section 3(a)(9) of the Securities Act as an exchange with existing security holders where no commission or other remuneration is paid or given for soliciting such exchange. The recipients of such options were the registrant’s employees, consultants or directors and received the options under the registrant’s 2000 Stock Plan or 2010 Equity Incentive Plan. The recipients of such shares of Series 2 redeemable convertible preferred stock received the warrants to purchase preferred stock in June 2010, which were subsequently amended and restated in July 2012. The recipients of securities in each of these transactions represented their intention to acquire the securities for investment only and not with view to or for sale in connection with any distribution thereof, and appropriate legends were affixed to the securities issued in these transactions. There were no other sales of unregistered securities during the year ended December 31, 2016. Purchases of Equity Securities by the Issuer None. 48 Performance Graph The following graph compares our cumulative total stockholder return on Impinj’s common stock with the NASDAQ Composite Index and the Philadelphia Semiconductor Index: This graph covers the period from July 21, 2016, using the closing price for the first day of trading immediately following the effectiveness of our initial public offering per SEC regulations, through December 31, 2016. This graph assumes that the value of the investment in Impinj’s common stock and each index (including reinvestment of dividends) was $100 on July 21, 2016. Use of Proceeds On July 20, 2016, our registration statement on Form S-1 (No. 333-211779) was declared effective for our initial public offering, or IPO. There has been no material change in the planned use of proceeds from our IPO from that described in the final prospectus dated July 20, 2016 filed with the SEC pursuant to Rule 424(b)(4) under the Securities Act. As of December 31, 2016, we have used an estimated $8.5 million of the proceeds from our IPO for working capital, the principal and accrued interest on the $5.0 million term loan pursuant to the mezzanine credit facility and other general corporate purposes. As of December 31, 2016, no portion of the proceeds from our IPO have been paid by us directly or indirectly to any of our directors or officers (or their associates) or persons owning ten percent or more of our common stock or to any other affiliates, other than payments in the ordinary course of business to officers for salaries and bonuses, and payments to our directors for service on our Board of Directors. Pending the uses described, we have invested the net proceeds in short-term, investment-grade interest-bearing securities such as U.S. government agencies, corporate bonds and notes and money market funds. 49 Item 6.

Management’s Discussion and Analysis of Financial Condition and Results of Operations You should read the following discussion and analysis together with our consolidated financial statements and the related notes to those statements included elsewhere in this report. This discussion contains forward-looking statements that involve risks and uncertainties. As a result of many factors, such as those set forth under “Risk Factors” and elsewhere in this report, our actual results may differ materially from those anticipated in these forward-looking statements. Overview Our vision is digital life for everyday items. Our mission is to connect these everyday items to business and consumer applications. We believe that by expanding the reach of the Internet to items such as retail apparel, medical supplies, pharmaceuticals, airline luggage, automotive parts, food – nearly everything – we can improve peoples’ lives. We were founded in 2000 and, since 2003, have been focused on our mission of item connectivity. Our platform delivers real-time information about an item’s unique identity, location and authenticity – what we refer to as Item Intelligence – through RAIN radio-frequency identification (RFID) technology. We have invested over $182 million developing our platform since 2003, including $172 million in research and development expense, $9 million in development agreement costs and $1 million in internal-use capitalized software costs. The Impinj platform comprises three layers that together connect items to applications. Figuratively, from bottom to top, they are an endpoint layer, a connectivity layer and a software layer. Within each layer we sell one or more product families. Our platform comprises: • • Endpoints . Our endpoint IC product family, branded Monza, comprises a family of miniature radios-on-a-chip that attach-to and uniquely identify their host items. We term the endpoint IC and its host item an “endpoint”. Our endpoint ICs power themselves from a reader’s radio waves so don’t need a battery, can wirelessly connect almost any item and are readable to 30 feet without line-of-sight. We launched our first endpoint IC, Monza 1, in 2005 and have brought to market five subsequent Monza product families. Each family has increased performance, offered new features and functionalities and reduced cost. Most recently, we introduced our Monza R6 product family, which has longer read range, improved ease-of-use and lower cost when compared with prior Monza products. We have shipped over 18 billion Monza endpoint ICs since 2005, including approximately 6.0 billion and 3.5 billion in the 12 months ended December 31, 2016 and 2015, respectively. Connectivity . Our connectivity layer comprises a family of readers, gateways and reader ICs that wirelessly identify, locate, authenticate and engage endpoints via RAIN. These connectivity products wirelessly provide power to, and communicate bidirectionally with, endpoint ICs, identifying and locating up to 1,000 items per second. o Readers and Gateways. Our readers read, write, authenticate or otherwise engage endpoint ICs. Our gateways integrate stationary readers with scanning antennas to locate and track endpoints. Our stationary reader product family, branded Speedway, comprises high- performance finished products. We launched our first Speedway reader in 2006 and have brought to market two subsequent Speedway product families as well as firmware/software enhancements. Our gateway product family integrates our Speedway readers with beamforming antennas to electrically steer a radio beam like a searchlight. We introduced our first gateway, xPortal, in 2010. xPortal is optimized for reading tags in transition zones such as doors and hallways. We introduced our xArray gateway in 2014. xArray is optimized for reading tags over a wide area such as store floors, manufacturing facilities and hospital rooms. We introduced our xSpan gateway in 2016, Like xPortal, xSpan is optimized for reading tags in transition zones such as doors and hallways. 52 o Reader ICs. Our reader IC product family, branded Indy, comprises a suite of ICs and systems-in-package, or SIPs, that combine our reader ICs with peripheral circuitry in an easy-to-use format. Our reader ICs and SIPs read, write, authenticate or otherwise engage end point ICs. We acquired our Indy business from Intel corporation in July 2008, at which time Intel was selling a single product, the R1000. We subsequently brought to market two additional Indy IC products, the R500 and R2000. More recently we introduced th e RS500 and RS2000 SIPS that reduce OEM and ODM product integration and time-to-market. Our partners typically place large orders for our reader ICs, securing their supply for an extended period of time but causing variability in our product orders and qua rterly reader IC revenue. • Software . Our software layer today comprises two products, ItemSense and ItemEncode. o o ItemSense is the operating system for our platform. It extracts Item Intelligence from the connectivity and endpoint layers and delivers that Item Intelligence to business and consumer applications. It also centralizes reader and gateway configuration, management and control through a management application program interface, or API. It is modular, scalable and secure and can operate on-premises, in hybrid-cloud or in cloud-based environments. ItemSense can connect, manage and process data from hundreds of readers or gateways. We began generating ItemSense revenue in the second half of 2016; however, as anticipated, our revenue to date has not been material as we continue our development and commercialization efforts. ItemEncode encodes item information into endpoint ICs. A single ItemEncode-enabled system can reliably encode many tens-of- thousands of endpoint ICs per hour. We introduced ItemEncode in 2014 and first generated revenue from ItemEncode deployments in the second half of 2014; however, our software revenue to date has not been material. We derive a substantial majority of our revenue from sales of our platform hardware and software. We also occasionally derive revenue from non-recurring engineering, or NRE, development agreements under which we develop custom products or services. Although we will continue to pursue strategic NRE opportunities, we expect NRE-based revenue to remain a small percentage of total revenue. We manage our business using a capital-efficient operating model that leverages third-party semiconductor foundries and subcontractors to produce and test our ICs and contract manufacturers to assemble and test our readers and gateways. We designed this production model to scale efficiently with volume. We leverage a partner channel comprising OEMs, ODMs, distributors, system integrators, VARs and software-solution partners to deliver our products and scale revenue. The efficiency of our operating model allows us to invest strategically in research and development, inventory and sales and marketing. • • • In 2016 and 2015, we invested $ 25.4 million and $17.8 million, respectively, in research and development, including expenses related to NRE development agreements and capitalized internal-use software-development costs. We intend to continue investing significantly in research and development to maintain our technology leadership. In 2016, we grew our ending inventory by $15.9 million over the ending inventory of $11.8 million at December 31, 2015 to meet growing demand for our products and to reduce lead times. We intend to continue investing in inventory in the near term. In 2016 and 2015, we invested $22.3 million and $14.6 million, respectively, in sales and marketing. We intend to continue investing in sales and marketing, including expanding our sales and marketing personnel to increase our selling opportunities. These investments will increase operating expenses on an absolute dollar basis for the foreseeable future. Many of these investments will occur in advance of us experiencing any direct benefit from them and may affect our profitability, or cause an operating loss, in future periods. 53 Our total revenue was $112.3 millio n, $78.5 million and $63.8 million for 2016, 2015 and 2014, respectively. Our net loss was $1.7 million for 2016 and our net income was $900,000 and $297,000 for 2015 and 2014, respectively. Our adjusted EBITDA was $5.1 million, $4.8 million and $4.9 milli on for 2016, 2015 and 2014, respectively. For a definition of adjusted EBITDA and a reconciliation of adjusted EBITDA to net income (loss), see “Selected Consolidated Financial Data—Adjusted EBITDA.” Factors Affecting Our Performance Investing in Growth We have invested, and plan to continue investing, significantly in research and development to enhance and extend our platform, including enhancing existing platform products and introducing new platform products. We plan to enhance our operating-system software, including its deployment models and functionalities. We plan to enhance our fixed readers and gateways and leverage them for platform deployments in retail, healthcare and other industries. We also plan to develop next-generation reader and endpoint ICs. We may enter into arrangements with customers, vendors and channel partners to fund all or a portion of certain of these research and development initiatives. If we are unsuccessful in attracting such funding, our operating results and product time-to-market may be adversely affected. We also are investing in sales and marketing and are deepening product integration with our software partners to accelerate the development and adoption of solutions based on our platform. These investments will increase research, development, sales and marketing expenses on an absolute dollar basis for the foreseeable future. Many of these investments will occur in advance of experiencing any direct benefit from them and may affect our profitability in future periods. Market Adoption Our financial performance generally depends upon the rate, scope and depth of end-user adoption of our platform in multiple industries, including the retail industry which is our largest end market. In 2013 and 2014 some major retailers, brand owners and other entities initiated new deployments, and in 2015 and 2016 began more rapid expansion, which increased our product sales. We believe these deployments indicate a trend toward greater RAIN adoption in retail and other markets, and we intend to continue i ntroducing new products to further grow our overall market adoption. For example, 2016 endpoint IC sales exceeded both our expectations and those of our industry’s analysts . Although we expect future-period endpoint IC growth rates to return to a growth ra te more in-line with the growth expectations of RAIN industry analysts, in the near term we are investing in endpoint IC inventory both to meet forecast demand and to enhance our ability to deliver in the event of another unexpected demand surge. In addition, we believe greater adoption of our software will increase the value of the other parts of our platform, which we believe will further drive adoption over the longer term. If market adoption of RAIN technology, and our platform products specifically, does not meet our expectations, our growth prospects and operating results will be adversely affected. In addition, if endpoint IC sales (one indicator of market adoption) exceed expectations or if we discount prices to win a particularly large opportunity, our revenue and profitability may be positively affected, but gross margins may be negatively affected depending on ASPs and product mix. Timing and Complexity of Customer Deployments From 2010 to 2016, our endpoint IC unit sales volume increased at a compounded annual growth rate of 36%. However, deployment of RAIN-based solutions has been uneven and unpredictable in scope, timing and implementation. For end users to gain business value from our platform, they typically must integrate our platform with their applications and information systems. End-users may only deploy certain of our hardware products, which may affect the value they derive from our platform, and in turn, our operating results. We have a large and multi-tiered partner channel which serves many markets and end users; we rely on these channel partners to deploy or integrate our platform and products with end user applications and information systems. If our partners fail to deploy or integrate our platforms and products as planned then sales of our products and our reputation may be adversely affected. As a result of these factors and our reliance on our channel partners, we may experience significant fluctuation in revenue on a quarterly basis, and we anticipate these factors will continue to characterize our business for the foreseeable future. Therefore, we focus on annual results as they are more relevant for planning and for evaluating our performance. 54 In addition, we may enter into NRE development agreements which typically include initi al funding with a requirement for us to meet certain milestones in order to receive additional funding for the NRE engagement. If we are unable to meet such milestones, we may not realize the full benefits of the NRE engagement. Average Selling Price We occasionally discount prices of our products to win opportunities, particularly large opportunities. In future periods we expect our hardware ASPs to fluctuate based on the level of discounting and competitive price pressures, and generally to decline over time. Historically, we have been able to implement manufacturing and quality improvements that effectively reduce the cost per unit of most of our products, allowing us to maintain, and in some cases increase, gross margins. Components of Results of Operations Revenue We currently generate revenue from the sale of platform products and from development, service and licensing agreements. Product Revenue We currently derive substantially all of our product revenue from sales of our endpoint ICs, reader ICs and readers and gateways, as follows: • • • We sell our endpoint ICs primarily to inlay manufacturers. In 2016, endpoint IC sales represented 77% of our product revenue, compared to 67% in 2015. We attribute this increase to our 73% growth in endpoint IC unit volumes between 2015 and 2016. We expect endpoint IC sales to represent a majority of our product revenue for the foreseeable future. In 2016, endpoint IC sales to inlay manufacturers Smartrac, Avery, Arizon and Shang Yang accounted for 65% of our total endpoint IC revenue, and 16%, 14%, 11% and 10% of our total revenue, respectively. We sell our reader ICs primarily to OEMs and ODMs through distributors. In 2016, sales to our top three reader IC customers accounted for 75% of our total reader IC revenue, but none individually represented more than 10% of our total revenue. We expect customer concentration for reader ICs to decrease over time as demand for RAIN solutions grows and the number of OEMs and ODMs increases. We sell our readers and gateways to VARs and system integrators primarily through distributors. We are beginning to sell software through these same partners as well as through ISVs. In 2016, sales to one distributor accounted for 52% of our readers and gateway revenue, but represented less than 10% of our total revenue. We expect revenue from reader, gateway and software sales to increase as a percentage of total revenue over time as a result of our investment in sales and marketing associated with our solutions business and our growing emphasis on software. We sell our products through a broad network of OEMs, ODMs and distribution channel partners; many of these channel partners sell multiple Impinj products. In addition, to take advantage of the benefits associated with our platform, end users must deploy multiple products. As a result, we evaluate our performance primarily on total product revenue rather than on the revenue associated with any particular product line. For our endpoint ICs and reader ICs, we generally recognize product revenue upon shipment because the relevant criteria for revenue recognition are met at that time. For our reader and gateway products, which are occasionally sold with other products and support, we allocate revenue to each separate deliverable on a relative fair-value basis and generally recognize revenue upon shipment or defer and recognize revenue ratably over the contract service period. We believe software revenue will grow over time, but it has not been material to date, and we expect modest software revenue for the foreseeable future. 55 Development, Service and Licensing Revenue Our development, service and licensing revenue includes revenue from services we perform under custom development agreements and for rights to technology through licenses. We derive substantially all our development, service and licensing revenue from NRE development agreements. We often receive payment from customers in advance of completion of deliverables. We record these payments as deferred revenue until they are earned, and we generally recognize revenue under these contracts using the percentage-of-completion method. We customize our development projects to the customer’s requirements and, therefore, our gross margin varies from project to project. We intend to pursue strategically important development agreements to fund product development. In the future we expect revenue from such agreements to fluctuate but over time decline as a percentage of total revenue. Cost of Revenue and Gross Margin Cost of product revenue includes costs associated with manufacturing our endpoint ICs, reader ICs, readers and gateways, including direct materials and manufacturing costs as well as associated overhead costs such as logistics, quality control, planning and procurement. We outsource manufacturing of our readers and gateways to a third-party contract manufacturer, and our costs for these devices are based on negotiated prices for finished goods. Cost of product revenue also includes charges for inventory write-downs, warranty costs and accrued losses on purchase commitments to third-party contract manufacturers. Our gross margins vary by product, with endpoint IC margins generally lower than total gross margins, and all other hardware and software product margins generally higher than total gross margins. As such, our total product gross margin varies from period to period as a function of product mix. Historical product gross margin and total gross margin has remained relatively consistent at between 50% and 55% for the interim and annual periods during the last three fiscal years. Cost of development, service, and licensing revenue consists primarily of direct labor and other costs, such as travel and materials, associated with fulfilling deliverables as part of an agreement. Our development agreements are customized to the customer’s requirements and our gross margin varies from project to project. Operating Expenses Research and Development Research and development expense consists primarily of salaries and related compensation costs, including stock-based compensation expense, for our product development personnel, contract developers, prototype materials and other expenses related to the development of new and innovative products and solutions. We expect research and development expense to increase in absolute dollars in future periods for platform product development. We expense research and development costs as we incur them. However, we do not record certain of our investments related to research and development as research and development expense. We classify costs that are directly attributable to development agreements as costs of development, service and licensing revenue. Costs incurred to develop software for internal use that meet the criteria for capitalization are capitalized in the period incurred and depreciated over the estimated useful life of the software, typically three years. Our total investment in research and development was $25.4 million, $17.8 million and $15.4 million in 2016, 2015 and 2014, respectively. These amounts include $25.2 million, $17.6 million and $14.3 million in research and development expense, $157,000, $113,000 and $169,000 of internal-use software development costs capitalized, and $14,000, $133,000 and $967,000 of development costs for NRE agreements in 2016, 2015 and 2014, respectively. Selling and Marketing Selling and marketing expense consists primarily of salaries and related variable compensation costs, including stock-based compensation expense for our sales personnel, as well as travel, advertising and promotional expenses and other related expenses. We anticipate that sales and marketing expense will increase in absolute dollars, as we increase personnel and focus on expanding our market penetration, developing strategic partnerships and driving adoption of our platform. We expect incentive sales compensation to fluctuate as a function of sales. 56 General and Administrative General and administrative expense consists primarily of salaries and related compensation costs, including stock-based compensation expense, for our executive, finance, human resources and information technology personnel, legal, accounting and other professional services, travel and related expenses, insurance, occupancy and other overhead costs. We expect our general and administrative expenses to increase in absolute dollars as we add personnel and facilities to support our growth. In addition, we will incur additional compliance and reporting costs as a public company. Interest Income (Expense) and Other Income (Expense), Net Interest expense consists primarily of interest on our credit facilities and amortization of deferred financing fees associated with such facilities. Interest income and other income (expense), net consists of interest income earned on our cash, cash equivalents and short-term investments, a payment from a third party in exchange for early termination of the lease for our corporate headquarters and, in periods prior to our initial public offering, changes in the fair value of outstanding redeemable convertible preferred stock warrants. 57 Results of Operations The following table present our results of operations for the periods indicated: YEAR ENDED DECEMBER 31, 2015 (in thousands, except per share amounts) 2014 2016 Statements of Operations Data: Revenue Cost of revenue (1) Gross profit Operating expenses: Research and development expense (1) Sales and marketing expense (1) General and administrative expense (1) Offering costs (1) Total operating expenses Income (loss) from operations Interest income (expense) and other income (expense), net Income (loss) before tax expense Income tax expense Net income (loss) Less: Accretion of preferred stock Net loss attributable to common stockholders Net loss per share attributable to common stockholders — basic and diluted (2) Weighted-average shares used to compute net loss per share attributable to common stockholders — basic and diluted Other Financial Information: Adjusted EBITDA (3) ____________ (1) Includes stock-based compensation as follows: Cost of revenue Research and development expense Sales and marketing expense General and administrative expense Offering costs Total stock-based compensation expense $ $ $ $ $ $ $ 112,287 52,834 59,453 25,185 22,330 12,426 — 59,941 (488) (1,017) (1,505) (168) (1,673) (6,258) (7,931) $ (0.74) $ $ 78,479 37,633 40,846 17,579 14,579 7,087 — 39,245 1,601 (535) 1,066 (166) 900 (11,301) (10,401) $ (2.67) $ 10,778 3,893 5,146 $ 4,751 $ 96 983 1,289 397 — 2,765 $ $ 31 305 692 150 — 1,178 $ $ 63,763 30,121 33,642 14,287 10,825 6,115 1,959 33,186 456 (63) 393 (96) 297 (11,301) (11,004) (3.30) 3,338 4,918 49 362 413 313 38 1,175 (2) (3) See note 2 of the notes to our consolidated financial statements included elsewhere in this report for an explanation of the calculation of our net loss per share attributable to common stockholders — basic and diluted. See “—Adjusted EBITDA” below. Adjusted EBITDA We use adjusted EBITDA as a key measure to understand and evaluate our core operating performance and trends, to prepare and approve our annual budget and to develop short- and long-term operational plans. In addition, we believe excluding certain expenses in calculating adjusted EBITDA can provide a useful measure for period-to-period comparisons of our business. Accordingly, we believe that adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results in the same manner as it does for our management and board of directors. 58 Adjusted EBITDA is not prepared in accordance with U.S. generally accepted accounting principles, or GAAP, and should not be considered in isolation of, or as an alternative to, measures prepared in accordance with GAAP. In addition, adjusted EBITDA is not based on any comprehensive set of accounting rules or principles. As a non-GAAP measure, adjusted EBITDA has limitations in that it does not reflect all of the amounts associated with our results of operations as determined in accordance with GAAP. Some of these limitations are that our adjusted EBITDA: • • • • • • • does not reflect interest or other income; does not reflect interest expense, or the cash requirements necessary to service interest or principal payments on our debt; does not reflect the amounts we paid in taxes or other components of our tax expense; does not reflect the non-cash charges of depreciation and amortization; does not reflect stock-based compensation expense; does not reflect offering costs written off due to delays in offering activities related to our initial public offering; and may be calculated differently than such metric calculated by other companies, limiting its usefulness as a comparative measure. Because of these limitations, you should consider adjusted EBITDA alongside other financial performance measures, including our financial results presented in accordance with GAAP.

More than 95% of the $34.4 million increase in product revenue was attributable to increased shipment volumes of our Monza R6 product family; partially offset by a modest decrease in average selling prices for our endpoint ICs. Reader and gateway shipment volumes increased by 11.2%. This increase was partially offset by a decrease in average selling prices due to volume pricing discounts for readers and gateways. Development, service and licensing revenue decreased in 2016 compared to 2015 as we completed work under development agreements in 2015 that were not replaced with new agreements in 2016. 60 Gross Profit YEAR ENDED DECEMBER 31, CHANGE 2015 VS. 2016 2016 2015 IN DOLLARS PERCENTAGE (in thousands, except percentages) Product gross profit Cost of development, service and licensing revenue gross profit Total gross profit Product gross margin Cost of development, service and licensing revenue gross margin Total gross margin $ $ 59,155 298 59,453 $ $ 52.9% 57.5 52.9 40,029 817 40,846 $ $ 51.7% 75.0 52.0 19,126 (519) 18,607 47.8% (63.5) 45.6 Product gross profit increased $19.1 million for 2016 compared to 2015 due to increased shipment volumes of our Monza R6 product family described above.

We cannot assure you that this pattern of product revenue growth will continue. Product revenue decreased sequentially quarter over quarter in the first quarter of 2016 as the volume of reader-IC products shipped was lower than the fourth quarter of 2015 as fewer OEM and ODM partners placed large orders with shipments in the first quarter. Our quarterly cost of revenue generally moves in line with the associated period’s total revenue. Product gross margin and total gross margin has remained relatively consistent at between 50% and 55% for the periods presented, fluctuating as a result of shifts in the mix of products shipped during each period and the portion of our total revenue attributable to development projects. Our development projects are customized to the customer’s requirements and, therefore, our development, service and licensing gross margin varies from project to project. We typically negotiate pricing with our OEM and ODM partners with an effectiv e date during the first quarter of every year, impacting both revenue and gross margins when compared with prior periods. Total operating expenses have generally increased sequentially quarter-over-quarter for all periods presented above, primarily due to the continued addition of personnel in connection with our business growth. We evaluate our total investment in technology development based upon the combined total of research and development costs and cost of development revenue which remained consistent period-over-period as a percentage of total revenue. Our total investment in technology development increased sequentially quarter-over-quarter for all periods presented above, primarily due to increases in headcount-related expenses from continued hiring to develop and enhance our products. 66 Adjusted EBITDA The following table sets forth a reconciliation of Adjusted EBITDA to net loss for each of the periods presented below. See “Adjusted EBITDA” under “Results of Operations” above in this Item 7 for additional information about why we have included Adjusted EBITDA in this report and how we use Adjusted EBITDA.

We had working capital of $123.3 million as of December 31, 2016. Historically, we funded our operations principally through the issuance of equity securities or the incurrence of debt. In 2016 and 2015, our principal uses of cash were funding operations to generate revenue growth, debt service payments, and capital expenditures. On July 26, 2016, we closed our initial public offering of 5,520,000 shares of common stock at an initial price to the public of $14.00 per share, including 720,000 shares of common stock pursuant to the underwriters’ option to purchase additional shares, resulting in aggregate net proceeds to us of $68.5 million after deducting underwriting discounts and commissions and offering costs. On December 7, 2016, we closed a follow-on public offering of 1,527,380 shares of common stock at an initial price to the public of $27.00 per share, resulting in aggregate net proceeds to us of $38.7 million after deducting underwriting discounts and commissions and offering costs. We intend to continue investing in the growth of our business, and there is no assurance that we will be able to consistently fund our business out of operating cash flows in the future. Sources of Funds We believe, based on our current operating plan, that our existing cash, cash equivalents, short-term investments and available borrowings under our senior credit facility will be sufficient to meet our anticipated cash needs for at least the next 12 months. From time to time, we may explore additional financing sources and means to lower our cost of capital, which could include equity, equity-linked and debt financing. In addition, in connection with any future acquisitions, we may require additional funding which may be provided in the form of additional debt, equity or equity-linked financing or a combination thereof. There can be no assurance that any additional financing will be available to us on acceptable terms. Senior Credit Facility We have a loan and security agreement, which we refer to as our senior credit facility, with Silicon Valley Bank. The senior credit facility provides for (1) a $10.5 million aggregate principal amount of outstanding term borrowings, (2) revolver borrowings up to the lesser of $15.0 million and a borrowing base tied to the amount of our eligible accounts receivable and inventory, (3) a $5.0 million sublimit under the revolver for the issuance of standby letters of credit and (4) an equipment term-loan facility of up to $2.0 million. 67 In connection wi th the amendment of our senior credit facility in May 2016, we incurred $10.5 million in term borrowings and used such borrowings to refinance $8.2 million in outstanding term borrowings. As amended, interest on the term loan accrues at a floating rate equ al to the lender’s prime rate plus 2.25% during a one year interest-only period and at a floating rate equal to the lender’s prime rate plus 1.75% after expiration of the interest-only period (6.0% at December 31, 2016). In June 2017, we must begin paying 36 equal monthly installments of principal, plus accrued and unpaid interest. We may at our option prepay the outstanding term loan balance by paying the lender all principal and accrued and unpaid interest plus a prepayment fee equal to $210,000 if the te rm loan is prepaid on or prior to the first anniversary of the May 2016 amendment, and $105,000 if the term loan is prepaid after the first anniversary but on or prior to the second anniversary of the May 2016 amendment. At December 31, 2016 , we had $ 10.5 million of term loan borrowings outstanding. All outstanding principal and accrued and unpaid interest on the term loan is due and payable in May 2020. Interest on revolver borrowings is payable monthly and accrued at a floating rate equal to the lender’s prime rate plus 2.25% at all times when our cash held at the bank plus the amount available to borrow on the revolver was less than or equal to $8.5 million, and 1.75% when our cash held at the bank plus the amount available to borrow on the revolver was g reater than $8.5 million for a period of at least 60 consecutive days (5.5% at December 31, 2016). The maturity date of the revolver is December 2017. At December 31, 2016, we had no outstanding revolver borrowings and we had available an additional $15.0 million in revolver borrowing capacity. As amended in May 2016, our senior credit facility also provides for up to $2.0 million in equipment term loans to fund purchases of eligible equipment. Equipment loans are available for borrowing for one year following the May 2016 amendment date and mature in May 2020. Equipment loans are repaid in 36 equal monthly installments of principal, plus accrued and unpaid interest, following each borrowing and accrue interest at a floating rate equal to the lender’s prime rate plus 1.75% (5.5% at December 31, 2016). We may at our option prepay the outstanding equipment loan balance by paying the lender all outstanding principal and accrued and unpaid interest plus a prepayment fee equal to 2.0% of the principal amount of each equipment loan prepaid if such equipment loan is prepaid on or prior to the first anniversary of the date such equipment loan was borrowed, and 1.0% of the principal amount of each equipment loan prepaid if such equipment loan is prepaid after the first anniversary of the date such equipment loan was borrowed. At December 31, 2016, we had $1.9 million of equipment loan borrowings outstanding.

The senior credit facility also requires us to maintain a minimum tangible net worth and liquidity ratio. We were in compliance with all covenants under our senior credit facility as of December 31, 2016 and 2015. Substantially all of our assets other than intellectual property are pledged as collateral under the senior credit facility. Mezzanine Credit Facility We had a mezzanine loan and security agreement, which we referred to as our mezzanine credit facility, with SG Enterprises II, LLC, which provided for a $5.0 million term loan which was drawn in September 2015. On July 26, 2016, we repaid without premium or penalty the principal and accrued interest on the $5.0 million term loan pursuant to the mezzanine credit facility and expensed unamortized debt discounts and issuance costs of $109,000. Interest on the term loan was payable monthly and accrued at a fixed per annum rate equal to 18.0%. 68 Use of Funds Our principal uses of cash are our operating expenses, inventory purchases, debt repayment and other working capital requirements. Historical Cash Flow Trends The following table shows a summary of our cash flows for the periods indicated: Net cash provided by (used in) operating activities Net cash used in investing activities Net cash provided by (used in) financing activities Operating Cash Flows 2016 YEAR ENDED DECEMBER 31, 2015 (in thousands) 2014 $ (9,497) $ (70,633) 103,645 3,456 $ (7,450) 7,176 (832) (817) (2,590) Net cash used in operating activities in 2016 primarily consisted of the net loss of $1.7 million, a $4.5 million increase in accounts receivable due to the timing of product shipments period over period, a $15.9 million increase in inventory to meet growing demand for our products and a $1.8 million increase in prepaid expenses and other assets. Offsetting these uses of cash in operations were benefits of a $5.3 million impact of non-cash items and a $8.9 million increase in accounts payable, accrued liabilities and accrued compensation and benefits due to the timing of when amounts came due. Net cash provided by operating activities in 2015 primarily consisted of $900,000 of net income, a $2.6 million impact of non-cash items, a $4.6 million increase in deferred rent due to tenant improvements and a net $2.3 million increase in accounts payable, accrued liabilities and accrued compensation and benefits due to the timing of when amounts came due. These cash flows were offset by a $3.3 million increase in accounts receivable due to the timing of product shipments period over period, a $466,000 decrease in deferred revenue and a $2.8 million increase in inventory. Net cash used in operating activities in 2014 primarily consisted of $297,000 of net income, a $3.1 million impact of non-cash items and a net $1.4 million increase in accounts payable, accrued liabilities and accrued compensation and benefits due to the timing of when amounts came due. These cash flows were offset by a $3.6 million increase in accounts receivable due to the timing of product shipments period over period, a $900,000 decrease in deferred revenue and an $800,000 increase in inventory. Investing Cash Flows Net cash used in investing activities in 2016 consisted of purchases of investments of $67.1 million and purchases of equipment of $3.5 million. Net cash used in investing activities consisted of purchases of equipment of $1.0 million and $7.5 million in 2014 and 2015, respectively. Net cash used in investing activities for 2014 was offset by $200,000 resulting from the release of cash restrictions under our lease agreement. Financing Cash Flows Net cash provided by financing activities in 2016 consisted of proceeds from public offerings of $108.1 million, net of offering costs of $10.4 million paid in 2016, $322,000 offering costs paid in 2015 and $626,000 unpaid offering costs at December 31, 2016, proceeds from borrowings of $61.4 million and proceeds of $662,000 from the exercise of stock options and warrants; offset by repayments of indebtedness of $65.3 million of principal under our senior credit facility and payments of $1.2 million for capital lease financing obligations. 69 Net cash used in financing activities in 2014 and 2015 consisted of repayments of indebt edness of $2.7 million and $6.1 million, respectively, of principal under our credit facility; payments of deferred offering costs of $0 and $322,000, respectively; and payments of $625,000 and $824,000, respectively, for capital lease financing obligation s; offset by proceeds from borrowings of $0 and $13.9 million, respectively, and proceeds of $702,000 and $538,000, respectively, from the exercise of stock options.

As of December 31, 2016, we had principal outstanding under our senior credit facility of $12.4 million with a blended interest rate of 5.9%. We manufacture products with a third-party manufacturer under recurring one-year agreements. We were committed to purchase $14.1 million of inventory as of December 31, 2016. Off-Balance Sheet Arrangements Since inception, we have not had any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or for another contractually narrow or limited purpose. Critical Accounting Policies and Significant Estimates Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements which have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities and related disclosure of contingent assets and liabilities, revenue and expenses at the date of the consolidated financial statements. Generally, we base our estimates on historical experience and on various other assumptions, in accordance with GAAP, that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under other assumptions or conditions. Critical accounting policies and estimates are those that we consider the most important to the portrayal of our financial condition and results of operations because they require our most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. Our critical accounting policies and estimates include those related to: • • • • revenue recognition; inventory; income taxes; and stock-based compensation. 70 Revenue Recognition We generate revenue from sales of our hardware and software products, development and service agreements and licensing agreements. We recognize product revenue when: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred; (3) the price is fixed or determinable; and (4) collection is probable. We typically consider hardware products are delivered upon shipment. Certain arrangements contain provisions for customer acceptance. Where we are unable to demonstrate that the customer acceptance provisions are met on shipment, we defer revenue until all acceptance criteria have been met or the acceptance clause or contingency lapses. For the sale of products to a distributor, we evaluate our ability to estimate returns, considering a number of factors including, the geography in which a sales transaction originates, payment terms and our relationship and past history with the distributor. Distributor agreements do not generally provide for a right of return for refund but do typically provide for a right of return in exchange for other similar products, subject to time and quantity limitations. If we are not able to estimate returns at the time of sale to a distributor, revenue recognition is deferred until there is persuasive evidence indicating the product has sold-through to an end user. Persuasive evidence of sell-through may include reports from distributors documenting sell-through activity, data indicating an order has shipped to an end user or other similar information. At the time of revenue recognition, we record reserves for sales returns which are estimated based on historical activity and expectations of future experience. We monitor and analyze actual experience and adjust reserves on a quarterly basis. We sell our reader and gateway products in combination with a limited hardware warranty against manufacturer defect. Our hardware warranty includes access to repair or replacement of hardware in the event of breakage or failure resulting directly from a manufacturer defect; this warranty is provided to all customers and considered an integral part of the initial product sale. Certain software is integrated with our reader and gateway products and is essential to the functionality of the integrated products. We also sell other software that configures, manages and controls readers and gateways which is not considered essential to the functionality of the hardware product. Our multi-element arrangements generally include a combination of hardware products, extended warranty, support and other non-essential software. We allocate revenue to software and non-software deliverables based on their relative fair value. Accounting principles establish a hierarchy to determine the selling price to be used for allocating revenue to non-software deliverables as follows: (1) vendor-specific objective evidence of selling price, or VSOE; (2) third-party evidence of selling price, or TPE; and (3) best estimated selling prices, or ESP. VSOE generally exists only when we sell the deliverable separately and is the price actually charged by us for that deliverable on a stand-alone basis. When VSOE cannot be established, we attempt to establish the selling price of each element based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. We are unable to reliably determine what similar competitor products’ selling prices are on a stand-alone basis and are therefore typically not able to determine TPE. When we are unable to establish selling price using VSOE or TPE, we use ESP in the allocation of arrangement consideration. The objective of ESP is to determine the price at which we would transact a sale if the product or service were sold on a stand-alone basis. Our ESPs for all products and services are calculated using a method consistent with the way management prices new products. We consider multiple factors in developing the ESPs for our products including our historical pricing and discounting practices, the costs incurred to manufacture the product or deliver the service, the nature of the customer relationship and market trends. In addition, we may consider other factors as appropriate, including the pricing of competitive alternatives if they exist and product-specific business objectives. We regularly review VSOE and ESP and maintain internal controls over the establishment and updates of these estimates. 71 For software deliverables, we recognize revenue in accordance with industry specific software accounting guidance for stand-alone software licenses and related support services. Revenue from software deliverables that do not require significant production, modification or customization of our software is generally recognized when: (1) delivery has occurred; (2) there is no customer acceptance clause in the contract; (3) there are no significant post-delivery obligations remaining; (4) the price is fixed; and (5) collection of the resulting receivable is reasonably assured. For transactions where we have established VSOE for the fair value of support services as measured by the renewal prices paid by our customers when the services are sold separately on a stand-alone basis, we use the residual method to determine the amount of software product revenue to be recognized. Under the residual method, the fair value of the undelivered elements is deferred and the remaining portion of the sales amount is recognized as license revenue. Support services revenue is deferred and recognized ratably over the period during which the services are to be performed, which is typically from one to three years. In those instances where we have not established VSOE of our support services, the license and service revenue is re cognized on a straight-line basis over the support period. Amounts allocated to extended support services sold with our reader products are deferred and recognized on a straight-line basis over the support services term. We account for nonrecurring engineering development agreements that involve significant production, modification or customization of our products by generally recognizing the revenue over the performance period using the percentage of completion, or POC, method. Advance payments under these agreements are deferred and recognized as earned. Under the POC method of accounting, sales and gross profit are recognized as work is performed based on the relationship between actual costs incurred and total estimated costs to complete the contract. Changes to the original estimates may be required during the life of the contract. Estimates are reviewed quarterly and the effect of any change in the estimated profitability for a contract is reflected in cost of sales. The use of the POC method of accounting involves considerable reliance on estimates in determining revenue, costs and profits and in assigning the amounts to accounting periods. We account for licensing and service agreements that do not involve significant production, modification or customization of our products generally by recognizing the revenue ratably over the performance period; advance payments under these agreements are initially deferred. We present revenue net of sales tax in our consolidated statements of operations. Shipping charges billed to customers are included in product revenue and the related shipping costs are included in cost of product revenue. Inventory Inventories consist of a combination of raw materials, work-in-progress and finished goods and are stated at the lower of cost or market. Cost is determined using the average costing method, which approximates the first in, first out, or FIFO, method. Reserves for excess and obsolete inventory are established based on our analysis of inventory levels and forecasted demand. Inventory write-downs are included in cost of revenue and were $420,000, $191,000 and $538,000 for the years ended December 31, 2016, 2015 and 2014, respectively. Additionally, we sold inventory previously written-down of $162,000, $492,000 and $0 for the years ended December 31, 2016, 2015 and 2014, respectively. We specifically identify inventory to write down by considering various factors at each reporting date, including inventory age, forecasted demand, new product release schedules, market conditions and other related factors. In considering forecasted demand, we also evaluate the likelihood of market adoption and demand from end users based upon each product’s lifecycle stage, longevity and historical product sales trends. Estimating the value of our inventory requires considerable judgment. Changes in our judgment could have a material impact on our results of operations, financial position and cash flows. 72 Income Taxes We use the liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to be in effect when such assets and liabilities are recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the year that includes the enactment date. We determine deferred tax assets, including historical net operating losses, and deferred tax liabilities, based on temporary differences between the book and tax bases of assets and liabilities. We believe that it is currently more likely than not that our deferred tax assets will not be realized and as such, we have recorded a full valuation allowance for these assets of $51.0 million. We evaluate the likelihood of the ability to realize deferred tax assets in future periods on a quarterly basis, and when appropriate evidence indicates we would release our valuation allowance accordingly. We utilize a two-step approach for evaluating uncertain tax positions. First, we evaluate recognition, which requires us to determine if the weight of available evidence indicates that a tax position is more likely than not to be sustained upon audit, including resolution of related appeals or litigation processes. If a tax position is not considered more likely than not to be sustained, no benefits of the position are recognized. Second, we measure the uncertain tax position based on the largest amount of benefit which is more likely than not to be realized on effective settlement. This process involves estimating our actual current tax exposure, including assessing the risks associated with tax audits, together with assessing temporary differences resulting from the different treatment of items for tax and financial reporting purposes. If actual results differ from our estimates, our net operating loss and credit carryforwards could be materially impacted. At December 31, 2016, we had federal NOLs of $100.0 million and federal research and experimentation credit carryforwards of $8.5 million which may be used to reduce future taxable income or offset income taxes due. Our realization of the benefits of the NOLs and credit carryforwards depends on sufficient taxable income in future years. We have established a valuation allowance against the carrying value of our deferred tax assets, as it is not currently more likely than not that we will be able to realize these deferred tax assets. In addition, utilization of NOLs and credits to offset future income subject to taxes may be subject to substantial annual limitations due to the “change in ownership” provisions of the Code and similar state provisions. Events that cause limitations in the amount of NOLs that we may utilize in any one year include, but are not limited to, a cumulative ownership change of more than 50%, as defined by Code Sections 382 and 383, over a three-year period. Utilization of our NOLs and tax credit carryforwards could be significantly reduced if a cumulative ownership change of more than 50% has occurred in our past or occurs in our future. We do not anticipate that the amount of our existing unrecognized tax benefits will significantly increase or decrease within the next 12 months. Due to the presence of NOLs in most jurisdictions, our tax years remain open for examination by taxing authorities back to 2000. Stock-Based Compensation Stock-based compensation cost is measured on the grant date, based on the estimated fair value of the award using a Black-Scholes option model and recognized as an expense over the employee’s requisite service period on a straight-line basis. We recorded stock-based compensation expense of $2.8 million, $1.2 million and $1.2 million in the years ended December 31, 2016, 2015 and 2014, respectively. At December 31, 2016, we had $8.6 million and $335,000 of total unrecognized stock-based compensation expense related to stock option grants and employee stock purchase plan awards that will be recognized over a weighted-average period of 2.9 years and 0.1 years, respectively. We expect to continue to grant stock options pursuant to our 2016 Equity Incentive Plan and to allow employees to purchase shares of our common stock pursuant to our 2016 Employee Stock Purchase Plan, and to the extent that we do, our stock-based compensation expense recognized in future periods will likely increase. 73 We account for stock-based compensation arrangemen ts with non-employees using a fair value approach. The fair value of these options is measured using the Black-Scholes option pricing model reflecting the same assumptions as applied to employee options in each of the reported periods, other than the expec ted life, which is assumed to be the remaining contractual life of the option. The compensation costs of these arrangements are subject to remeasurement over the vesting terms as earned. Prior to the closing of our initial public offering, we granted stock options at exercise prices believed to be equal to the fair value of the common stock underlying such options as determined by the board of directors, with input from management, on the date of grant. Because such grants occurred prior to the public trading of our common stock, the board of directors exercised significant judgment in determining the fair market value of our common stock. The valuations were consistent with the guidance and methods outlined in the AICPA Practice Aid, Valuation of Privately-Held-Company Equity Securities Issued as Compensation , or AICPA Practice Aid, for all option grant dates. After the closing of the initial public offering, we granted stock options with exercise prices based on market prices. Our Black-Scholes option-pricing model requires the input of highly subjective assumptions, including the expected volatility of the price of our common stock, the expected term of the option, risk-free interest rates, the expected dividend yield of our common stock and, for the period prior to our IPO, the fair value of the underlying common stock . These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and different assumptions are used, our stock-based compensation expense could be materially different in the future. In determining the fair value of stock options granted, the following weighted-average assumptions were used in the Black-Scholes option pricing model for awards granted in the periods indicated: Risk-free interest rates Expected term Expected dividends yield Volatility Recent Accounting Pronouncements EMPLOYEE STOCK PURCHASE PLAN YEAR ENDED DECEMBER 31, 2016 0.4% 0.5 years None 61.8% 2016 1.1% – 1.4% 4.3 – 6.1 years None 40.8% – 49.5% STOCK OPTIONS YEAR ENDED DECEMBER 31, 2015 1.2% – 1.6% 4.3 – 6.0 years None 41.5% – 43.4% 2014 1.8% – 2.0% 6.0 years None 43.8% – 46.9% For information on recent accounting pronouncements, please refer to Note 2 to our consolidated financial statements included elsewhere in this report. JOBS Act We are an emerging growth company under the JOBS Act. The JOBS Act provides that an emerging growth company can delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have elected to avail ourselves of this exemption. 74 Subject to certa in conditions set forth in the JOBS Act, if, as an “emerging growth company,” we choose to rely on certain exemptions provided for in the JOBS Act we may not be required to, among other things, (1) provide an auditor’s attestation report on our system of i nternal controls over financial reporting pursuant to Section 404, (2) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (3) comply w ith any requirement that may be adopted by the PCAOB regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis) and (4) dis close certain executive compensation related items such as the correlation between executive compensation and performance, and comparisons of the CEO’s compensation to median employee compensation. These exemptions will apply for a period of five years fol lowing the completion of our initial public offering or until we are no longer an “emerging growth company,” whichever is earlier. Item 7A. Quantitative and Qualitative Disclosures About Market Risk We are exposed to market risks in the ordinary course of our business. These risks primarily consist of fluctuations in interest rates. Interest Rate Risk U nder our current investment policy, we invest our excess cash in money market funds, U.S. government agency securities, corporate bonds and notes and commericial paper . Our current investment policy seeks first to preserve principal, second to provide liquidity for our operating and capital needs and third to maximize yield without putting our principal at risk. We do not enter into investments for trading or speculative purposes. We had cash, cash equivalents and short-term investments of $100.5 million and $10.1 million as of December 31, 2016 and 2015, respectively. Our investments are exposed to market risk due to the fluctuation of prevailing interest rates that may reduce the yield on our investments or their fair value. As our investment portfolio is short-term in nature, we do not believe an immediate 10% increase in interest rates would have a material effect on the fair market value of our portfolio, and therefore we do not expect our results of operations or cash flows to be materially affected by a sudden change in market interest rates. We are subject to interest rate risk in connection with the borrowings under our senior credit facility, which accrue interest at variable rates. As of December 31, 2016, our borrowings under our senior credit facility had a blended rate of 5.9%. Assuming the revolver borrowings under the senior credit facility are fully drawn and holding other variables constant, a 100 basis-point increase in interest rates, occurring January 1, 2017 and sustained throughout the period ended December 31, 2017, would result in an increase in interest expense and a decrease in our cash flows and income before taxes of approximately $275,000. Inflation Risk We do not believe that inflation has had a material effect on our business, financial condition or results of operations. If our costs were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could adversely affect our business, financial condition and results of operations. Foreign Currency Exchange Risk Prices for our products are denominated in U.S. dollars, and as a result, we do not face significant risk with respect to foreign currency exchange rates. 75 Item 8.

Note 2. Summary of Significant Accounting Policies Accounting Principles We prepared the consolidated financial statements and accompanying notes in accordance with accounting principles generally accepted in the United States of America. Principles of Consolidation Our consolidated financial statements include the accounts of Impinj, Inc. and our wholly-owned subsidiaries Impinj RFID Technology (Shanghai) Co., Ltd., located in China, Impinj UK Ltd., located in United Kingdom, Impinj Japan LLC, located in Japan, and Impinj International, Ltd., located in the Cayman Islands. All intercompany transactions have been eliminated in consolidation. Public Offerings On July 26, 2016, we closed our initial public offering of 5,520,000 shares of common stock at an initial price to the public of $14.00 per share, including 720,000 shares of common stock pursuant to the underwriters’ option to purchase additional shares, resulting in aggregate net proceeds to us of $68.5 million after deducting underwriting discounts and commissions and offering costs. Upon the effectiveness of the registration statement related to the initial public offering on July 20, 2016, all of our outstanding shares of redeemable convertible preferred stock and outstanding preferred stock warrants, which automatically net exercised, converted into 8,531,146 shares and 123,759 shares, respectively, of common stock. The related carrying value of the redeemable convertible preferred stock and warrants of $106.1 million and $505,000, respectively, were reclassified to common stock and additional paid-in capital. On December 7, 2016, we closed our follow-on public offering of 1,527,380 shares of common stock at a price to the public of $27.00 per share, resulting in aggregate net proceeds to us of $38.7 million after deducting underwriting discounts and commissions and offering costs. 84 Reverse Stock Split On June 16, 2016, our board of directors and stockholders approved an amendment to our certificate of incorporation to effect a reverse split of shares of our authorized, issued and outstanding common stock and redeemable convertible preferred stock at a 1-for-12 ratio. The reverse stock split was effected on July 8, 2016. The par value of our common stock and the par value of our redeemable convertible preferred stock were not adjusted as a result of the reverse stock split. All authorized, issued and outstanding shares of common stock and redeemable convertible preferred stock, warrants for common stock and redeemable convertible preferred stock, options to purchase common stock and the related per share amounts contained in these consolidated financial statements have been retroactively adjusted to reflect this reverse stock split for all periods presented. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the financial statements, as well as the reported amounts of revenue and expenses during the periods presented. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, reserve for returns, collectability of accounts receivable, estimated costs to complete development contracts, warranty obligations, deferred revenue, inventory excess and obsolescence, depreciable lives of fixed assets, the determination of the fair value of stock awards and warrants and accrued liabilities, compensation and employee related benefits. To the extent there are material differences between these estimates, judgments, or assumptions and actual results, our financial statements will be affected. Risks and Uncertainties Inherent in our business are various risks and uncertainties, including that we are developing advanced technologies and new applications in a rapidly changing industry. These risks include the failure to develop and extend our products and the rejection of our products by consumers, as well as other risks and uncertainties. If we do not successfully implement our business plan, certain assets may not be recoverable, certain liabilities may not be paid and investments in our capital stock may not be recoverable. Our success depends upon the acceptance of our technology, development of sales and distribution channels and our ability to generate significant revenue from the use of our technology. Concentrations of Credit Risk Financial instruments , which potentially subject us to concentrations of credit risk, consist primarily of cash equivalents, investments and accounts receivable. We place cash and cash equivalents and investments with major financial institutions, which management assesses to be of high credit quality, in order to limit exposure of our investments. We extend credit to customers based upon an evaluation of the customer’s financial condition and generally collateral is not required. The following table presents t otal revenue and accounts receivable concentration as of the dates presented: Revenue: Customer A Customer B Customer C Customer D Customer E 2016 YEAR ENDED DECEMBER 31, 2015 2014 16% 14 11 10 9 60% 14% 10 9 15 16 64% 11% 11 14 6 12 54% 85 Accounts Receivable: Customer A Customer C Customer D Customer E Customer F Concentration of Supplier Risk AS OF DECEMBER 31, 2016 2015 15% 8 11 11 18 63% 15% 12 20 11 — 58% We outsource the manufacturing and production of our hardware products to a limited number of suppliers. Although there are a limited number of manufacturers for hardware products, we believe that other suppliers could provide similar products on comparable terms. A change in suppliers, however, could cause a delay in manufacturing and a possible loss of sales, which would adversely affect our operating results. Cash and Cash Equivalents Cash and cash equivalents consist of cash deposits. We deposit our cash and cash equivalents primarily with one major financial institution, and our balances consistently exceed federally insured limits. We have not experienced any losses on our cash and cash equivalents. We define cash and cash equivalents to be all highly liquid investments purchased with an original or remaining maturity of three months or less at the date of purchase. Investments Our investments consist of fixed income securities, which include U.S. government agency securities, corporate notes and bonds and commercial paper. As the investments are available to support current operations, our available-for-sale securities are classified as short-term investments. Available-for-sale securities are carried at fair value with unrealized gains and losses reported as a component of accumulated other comprehensive income (loss) in stockholders’ equity (deficit), while realized gains and losses and other-than-temporary impairments are reported as a component of net income (loss) based on specific identification. An impairment charge is recorded in the consolidated statements of operations for declines in fair value below the cost of an individual investment that are deemed to be other than temporary. We assess whether a decline in value is temporary based on the length of time that the fair market value has been below cost, the severity of the decline and the intent and ability to hold or sell the investment. We did not identify any investments as other-than-temporarily impaired as of December 31, 2016. We had no cash equivalents and available-for-sale investments as of December 31, 2015. 86 The following table presents the amortized cost, gross unrealized gains and losses, and fair value of our cash, cash e quivalents and available-for-sale investments as of December 31, 2016 (in thousands): Cash Cash equivalents: Money market funds U.S. government agency securities Corporate notes and bonds Commercial Paper Short-term investments: U.S. government agency securities Corporate notes and bonds Commercial Paper Total assets measured at fair value Amortized Cost December 31, 2016 Gross Unrealized Gains Gross Unrealized Losses Fair Value $ 10,667 $ — $ — $ 10,667 14,065 4,996 959 2,948 36,535 19,259 11,122 100,551 $ $ — 1 — — 6 2 — 9 $ — — — — (10) (9) — (19) $ 14,065 4,997 959 2,948 36,531 19,252 11,122 100,541 T he contractual maturities are due in one year or less on our available-for-sale investments as of December 31, 2016. Accounts Receivable Accounts receivable consists of amounts billed currently due from customers and amounts earned not yet billed on development agreements, net of an allowance for doubtful accounts and an allowance for sales returns and price exceptions. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in existing accounts receivable and is determined based on historical write-off experience and on specific customer accounts believed to be a collection risk. Account balances are written off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. We record our sales returns and price exceptions allowance based on historical returns experience. The following table summarizes our allowance for doubtful accounts: Allowance for doubtful accounts: During year ended December 31, 2016 During year ended December 31, 2015 During year ended December 31, 2014 BALANCE AT BEGINNING OF YEAR CHARGED TO COSTS AND EXPENSES WRITE- OFFS BALANCE AT END OF YEAR $ $ 65 50 58 (in thousands) $ 42 15 (8) $ — — — 107 65 50 The following table summarizes our allowance for sales returns and price exceptions: Allowance for sales returns and price exceptions: During year ended December 31, 2016 During year ended December 31, 2015 During year ended December 31, 2014 BALANCE AT BEGINNING OF YEAR CHARGED TO COSTS AND EXPENSES WRITE- OFFS BALANCE AT END OF YEAR $ 220 312 347 (in thousands) $ 702 393 450 (745) $ (485) (485) 177 220 312 $ 87 Inventory Inventories consist of a combination of raw materials, work-in-progress and finished goods and are stated at the lower of cost or market. Cost is determined using the average costing method, which approximates the first in, first out, or FIFO, method. We establish reserves for excess and obsolete inventory based on our analysis of inventory levels and future sales forecasts. The following table presents the detail of inventories as of the dates presented: Raw materials Work-in-process Finished goods Total Inventory DECEMBER 31, 2016 2015 (in thousands) 5,482 5,556 16,696 27,734 $ $ 852 3,269 7,716 11,837 $ $ Inventory write-downs are included in cost of revenue and were $420,000, $191,000 and $538,000 for 2016, 2015 and 2014, respectively. We sold inventory previously written-down of $162,000, $492,000 and $0 during 2016, 2015 and 2014, respectively. We specifically identify inventory to write down by considering various factors at each reporting date, including inventory age, forecasted demand, new product release schedules, market conditions and other related factors. In considering forecasted demand, we also evaluate the likelihood of market adoption and demand from end users based upon each product’s lifecycle stage, longevity and historical product sales trends. Estimating the value of our inventory requires considerable judgment. Changes in our judgment could have a material impact on our results of operations, financial position and cash flows. Long-Lived Assets and Intangible Assets Long-lived assets include property and equipment. We assess the carrying value of our long-lived assets and intangible assets with a definite life when indicators of impairment exist, and we recognize an impairment loss when the carrying amount of an asset is not recoverable from the undiscounted cash flows expected to result from the use and eventual disposition of the asset. Impairment losses are measured by comparing the carrying amount of a long-lived asset to its fair value. Identifiable intangible assets comprise purchased customer lists, patents and developed technologies. Identifiable intangible assets are amortized over their estimated useful lives, ranging from four to eight years, using the straight-line method, which approximates the expected use of these assets. As of December 31, 2016, all definite-lived intangible assets were fully amortized. We record property and equipment at cost, determine depreciation using the straight-line method over the estimated useful lives of the assets, capitalize additions and improvements that increase the value or extend the life of an asset, expense ordinary repairs and maintenance as incurred, and amortize leasehold improvements over the shorter of the term of the lease or the estimated useful lives of the assets. 88 Goodwill Goodwill represents the excess of the purchase price over the fair value of the net identified assets acquired in a business combination. We evaluate our goodwill for impairment annually on September 30 or when indicators for impairment exist, and we write down goodwill when impaired. To evaluate goodwill for impairment, we qualitatively assess whether it is more likely than not that the fair value of our sole reporting unit is less than the carrying amount. If so, we proceed to the first step of the goodwill impairment test in which we identify potential impairment by performing a quantitative assessment, comparing the fair value of the reporting unit to the potentially impaired value, and we proceed to step two of the impairment analysis in which we record an impairment loss equal to the excess. Indicators of impairment in our qualitative assessment would include: the impacts of significant adverse changes in legal factors; market and economic conditions; the result of our operational performance and strategic plans; adverse actions by regulators; unanticipated changes in competition and market share; and the potential for sale or disposal of all or a significant portion of our business. No triggering events occurred during 2016 and 2015. Revenue Recognition We generate revenue from sales of our hardware and software products, and from development and service agreements and licensing agreements. We recognize product revenue when: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred; (3) the price is fixed or determinable; and (4) collection is probable. Hardware products are typically considered delivered upon shipment. Certain arrangements contain provisions for customer acceptance. Where we are unable to demonstrate that the customer acceptance provisions are met on shipment, revenue is deferred until all acceptance criteria have been met or the acceptance clause or contingency lapses. For the sale of products to a distributor, we evaluate our ability to estimate returns, considering a number of factors including, the geography in which a sales transaction originates, payment terms and our relationship and past history with the distributor. Distributor agreements do not generally provide for a right of return for refund but do typically provide for a right of return in exchange for other similar products, subject to time and quantity limitations. If we are not able to estimate returns at the time of sale to a distributor, revenue recognition is deferred until there is persuasive evidence indicating the product has sold-through to an end user. Persuasive evidence of sell-through may include reports from distributors documenting sell-through activity, data indicating an order has shipped to an end user or other similar information. At the time of revenue recognition, we record reserves for sales returns which are estimated based on historical activity and expectations of future experience. We monitor and analyze actual experience and adjust reserves on a quarterly basis. Our reader and gateway products are sold in combination with a limited hardware warranty against manufacturer defect. Our hardware warranty includes access to repair or replacement of hardware in the event of breakage or failure resulting directly from a manufacturer defect; this warranty is provided to all customers and considered an integral part of the initial product sale. Certain software is integrated with our reader and gateway products and is essential to the functionality of the integrated products. We also sell other software that configures, manages and controls readers and gateways which is not considered essential to the functionality of the hardware product. 89 Our multi-element arrangements generally include a combination of hardware products, extended warranty, support and other non-essential software. We allocate revenue to software and non-software deliverables based on their relative fair va lue. Accounting principles establish a hierarchy to determine the selling price to be used for allocating revenue to non-software deliverables as follows: (1) vendor-specific objective evidence of selling price, or VSOE; (2) third-party evidence of selling price, or TPE; and (3) best estimated selling prices, or ESP. VSOE generally exists only when we sell the deliverable separately and is the price actually charged by us for that deliverable on a stand-alone basis. When VSOE cannot be established, we attem pt to establish the selling price of each element based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. We are unable to reliably determine what similar competitor products’ selling prices are on a stand- alone basis and are therefore typically not able to determine TPE. When we are unable to establish selling price using VSOE or TPE, we use ESP in the allocation of arrangement consideration. The objective of ESP is to determine the price at which we would transact a sale if the product or service were sold on a stand-alone basis. Our ESPs for all products and services are calculated using a method consistent with the way management prices new products. We consider multiple factors in developing the ESPs for our products including our historical pricing and discounting practices, the costs incurred to manufacture the product or deliver the service, the nature of the customer relationship and market trends. In addition, we may consider other factors as appropriate, including the pricing of competitive alternatives if they exist and product-specific business objectives. We regularly review VSOE and ESP and maintain internal controls over the establishment and updates of these estimates. For software deliverables, we recognize revenue in accordance with industry specific software accounting guidance for stand-alone software licenses and related support services. Revenue from software deliverables that do not require significant production, modification or customization of our software is generally recognized when: (1) delivery has occurred; (2) there is no customer acceptance clause in the contract; (3) there are no significant post-delivery obligations remaining; (4) the price is fixed; and (5) collection of the resulting receivable is reasonably assured. For transactions where we have established VSOE for the fair value of support services as measured by the renewal prices paid by our customers when the services are sold separately on a stand-alone basis, we use the residual method to determine the amount of software product revenue to be recognized. Under the residual method, the fair value of the undelivered elements is deferred and the remaining portion of the sales amount is recognized as license revenue. Support services revenue is deferred and recognized ratably over the period during which the services are to be performed, which is typically from one to three years. In those instances where we have not established VSOE of our support services, the license and service revenue is recognized on a straight-line basis over the support period. Amounts allocated to extended support services sold with our reader products are deferred and recognized on a straight-line basis over the support services term. We account for nonrecurring engineering development agreements that involve significant production, modification or customization of our products by generally recognizing the revenue over the performance period using the percentage of completion, or POC, method. Advance payments under these agreements are deferred and recognized as earned. Under the POC method of accounting, sales and gross profit are recognized as work is performed based on the relationship between actual costs incurred and total estimated costs to complete the contract. Changes to the original estimates may be required during the life of the contract. Estimates are reviewed quarterly and the effect of any change in the estimated profitability for a contract is reflected in cost of sales. The use of the POC method of accounting involves considerable reliance on estimates in determining revenue, costs and profits and in assigning the amounts to accounting periods. We account for licensing and service agreements that do not involve significant production, modification or customization of our products generally by recognizing the revenue ratably over the performance period; advance payments under these agreements are initially deferred. We present revenue net of sales tax in our consolidated statements of operations. Shipping charges billed to customers are included in product revenue and the related shipping costs are included in cost of product revenue. 90 Guarantees and Product Warranties In the normal course of business to facilitate sales of our products, we indemnify other parties, including customers, distributors, resellers and parties to other transactions with us, with respect to certain matters. We have agreed to hold the other party harmless against losses arising from a breach of representations or covenants, from intellectual property infringement and from other claims made against certain parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. We provide limited warranty coverage for most products, generally ranging from a period of 90 days to one year from the date of shipment. A liability is recorded for the estimated cost of product warranties based on historical claims, product failure rates and other factors when the related revenue is recognized. We review these estimates periodically and adjust the warranty reserves as actual experience differs from historical estimates or other information becomes available. The warranty liability primarily includes the anticipated cost of materials, labor and shipping necessary to repair or replace the product. Accrued warranty costs in 2016 and 2015 were not material. Research and Development Costs Research and development costs are expensed as incurred and consist of salaries and related benefits of product development personnel, contract developers, prototype materials and other expenses related to the development of new and improved products. Foreign Currency The functional currency for all of our subsidiaries is the U.S. dollar. All foreign currency transactions are initially measured and recorded in U.S. dollars using the exchange rate on the date of the transaction. Foreign currency denominated assets and liabilities are remeasured at the end of each reporting period using the exchange rate at that date. We record translation gains and losses in other income (expense), net on the consolidated statements of operations. Income Taxes We use the liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to be in effect when such assets and liabilities are recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the year that includes the enactment date. We determine deferred tax assets, including historical net operating losses, and deferred tax liabilities, based on temporary differences between the book and tax bases of assets and liabilities. We believe that it is currently more likely than not that our deferred tax assets will not be realized and as such, we have recorded a full valuation allowance for these assets. We utilize a two-step approach for evaluating uncertain tax positions. First, we evaluate recognition, which requires us to determine if the weight of available evidence indicates that a tax position is more likely than not to be sustained upon audit, including resolution of related appeals or litigation processes, if any. If a tax position is not considered more likely than not to be sustained, no benefits of the position are recognized. Second, we measure the uncertain tax position, which is based on the largest amount of benefit which is more likely than not to be realized on effective settlement. This process involves estimating our actual current tax exposure, including assessing the risks associated with tax audits, together with assessing temporary differences resulting from the different treatment of items for tax and financial reporting purposes. If actual results differ from our estimates, our net operating loss and credit carryforwards could be materially impacted. Stock-Based Compensation We have stock-based compensation plans that are more fully described in Note 8. 91 We account for stock-b ased compensation at fair value. Stock-based compensation costs are recognized based on their grant date fair value estimated using the Black-Scholes model. In valuing our options, we make assumptions about weighted-average expected lives, risk-free intere st rates, volatility and dividend yields . We use the straight-line method of allocating stock-based compensation cost over the requisite service period of the related award. For awards granted under our 2016 Equity Incentive Plan, we account for forfeitur es as they occur and estimate the weighted-average expected life of the options as the average of the vesting option schedule and the term of the award, since we do not have sufficient historical exercise data as a public company to provide a reasonable ba sis upon which to estimate expected term. The term of the award is estimated using the simplified method, as awards are plain vanilla stock options. We estimated the risk-free interest rate for the expected term of the options based on the U.S. Treasury yi eld curve in effect at the time of grant. As we do not have an extensive public trading history for shares of our common stock, the expected volatility is estimated using a combination of the published historical volatilities of similar entities whose shar e prices are publicly available and our historical volatility since becoming a publicly traded company . We have not paid and do not anticipate paying cash dividends on common stock; therefore, the expected dividend yield is assumed to be zero. We account for equity instruments issued to nonemployees at fair value. We value all transactions in which we receive services for the issuance of equity instruments using the fair value of the services received or by using the Black-Scholes model. The measurement date of the fair value of the equity instrument issued is the earlier of the date on which the counterparty’s performance is complete or the date on which it is probable that performance will occur. Stock-based compensation expense on options granted to nonemployees was not material for 2016 and 2015. Warrant Liability We account for warrant liabilities at fair value. Warrant liability costs are recognized based on their grant date fair value estimated using the Black-Scholes option pricing model. To date, all warrants have been issued in connection with entering into or refinancing of our credit facilities and the costs of the warrants were accounted for as a debt discount which is amortized and recognized in interest expense over the term of the associated credit facility. Warrants issued to purchase preferred stock were adjusted to fair value at each period end as estimated using the Black-Scholes model and the associated change in fair value is included in other income (expense), net on the consolidated statements of operations. Net Loss per Share Attributable to Common Stockholders Net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding. We have outstanding stock options, unvested common stock subject to repurchase, warrants and convertible preferred stock, which are included in the calculation of diluted net loss attributable to common stockholders per share whenever to do so would be dilutive. We calculate basic and diluted net loss per share attributable to common stockholders in conformity with the two-class method required for companies with participating securities. We consider all series of convertible preferred stock to be participating securities. Under the two-class method, the net loss attributable to common stockholders is not allocated to the convertible preferred stock as the holders of convertible preferred stock do not have a contractual obligation to share in losses. The diluted net loss per share attributable to common stockholders is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, convertible preferred stock, options to purchase common stock and warrants to purchase common stock and convertible preferred stock are considered potentially dilutive securities but have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is antidilutive. Basic and diluted net loss per share was the same for each period presented, as the inclusion of all potential common shares outstanding would have been antidilutive. 92 For the periods presented, the following table provides a reconciliation of the numerator and denominator used in computing basic and diluted net income (loss) per share attributable to common stockholders : Numerator: Net income (loss) Less: Accretion of preferred stock Net loss attributable to common stockholders—basic and diluted Denominator: Weighted-average common shares outstanding Weighted-average unvested shares of common stock subject to repurchase Weighted-average shares used to compute net loss per share attributable to common stockholders—basic and diluted Net loss per share attributable to common stockholders—basic and diluted FOR THE YEAR ENDED DECEMBER 31, 2015 (in thousands, except per share amounts) 2014 2016 $ $ $ (1,673) $ (6,258) (7,931) $ 10,904 (126) 10,778 (0.74) $ $ 900 (11,301) (10,401) $ 4,067 (174) 3,893 (2.67) $ 297 (11,301) (11,004) 3,489 (151) 3,338 (3.30) The following outstanding options, warrants and shares of preferred stock were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods presented because their effect would have been antidilutive: Redeemable convertible preferred stock Common stock warrants Redeemable convertible preferred stock warrants Unvested shares of common stock subject to repurchase Stock options Offering Costs FOR THE YEAR ENDED DECEMBER 31, 2015 (in thousands) 7,885 25 264 136 1,896 2016 — — — 118 2,310 2014 7,885 25 264 216 2,007 Offering costs, consisting of legal, accounting and other fees and costs related to our public offerings, were capitalized. Total offering costs of approximately $4.1 million were deferred through the completion of the public offerings and upon closing of each of the public offerings in 2016 were reclassified to additional paid-in capital as a reduction of the proceeds. There were $0 and $637,000 of deferred offering costs as of December 31, 2016 and 2015, respectively. Recently Issued Accounting Standards In January 2017, the Financial Accounting Standards Board , or FASB, issued guidance simplifying the test for goodwill impairment. This standard eliminates Step 2 from the goodwill impairment test, instead requiring an entity to recognize a goodwill impairment charge for the amount by which the goodwill carrying amount exceeds the reporting unit’s fair value. This guidance is effective for interim and annual goodwill impairment tests in fiscal years beginning after December 15, 2019, and early adoption is permitted. This guidance must be applied on a prospective basis. We expect to adopt this guidance for interim and annual goodwill impairment tests performed on testing dates after January 1, 2017. We do not expect the adoption of this guidance to have a material impact on our financial position, results of operations or cash flows. 93 In December 2016, the FASB issued amendments to address various technical corrections and improvements. Most of the amendments are effective upon issuance, while six of the amendments require transition guidance. The amendments applicable to our business have been adopted for the year ended December 31, 2016. The adoption of these amendments did not have a material impact on our financial position, results of operations or ca sh flows. In December 2016, the FASB issued guidance to narrow the definition of a business. This standard provides guidance to assist entities with evaluating when a set of transferred assets and activities is a business. This guidance is effective for interim and annual reporting periods beginning after December 15, 2017, and early adoption is permitted. This guidance must be applied prospectively to transactions occurring within the period of adoption. We expect to adopt this guidance on January 1, 2018. We do not expect the adoption of this guidance to have a material impact on our financial position, results of operations or cash flows. In August 2016, the FASB issued guidance on the classification of certain cash receipts and cash payments in the statement of cash flows. This guidance is effective for interim and annual reporting periods beginning after December 15, 2017, and early adoption is permitted. The adoption of this guidance requires a retrospective transition method to each period presented. We adopted this guidance in the interim period ending on December 31, 2016. The adoption of this guidance did not have any impact on our statements of cash flows. In June 2016, the FASB issued guidance on the measurement of credit losses on financial instruments, which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost, replacing the existing incurred loss impairment model. This guidance is effective for interim and annual reporting periods beginning after December 15, 2019. The adoption of this guidance requires a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. We have not yet determined our approach to adoption or the impact the adoption of this guidance will have on our financial position, results of operations or cash flows. In March 2016, the FASB issued guidance on several aspects of the accounting for share-based payment transactions, including the income tax consequences, impact of forfeitures, classification of awards as either equity or liabilities and classification on the statement of cash flows. This guidance is effective for interim and annual reporting periods beginning after December 15, 2016, and early adoption is permitted. We adopted this guidance on January 1, 2017 using the modified retrospective approach through a cumulative-effect adjustment to beginning accumulated deficit, and we have elected to account for forfeitures as they occur beginning on January 1, 2017. The adoption of this guidance did not have a material impact on our financial position, results of operations or cash flows. In February 2016, the FASB issued guidance on leases. This standard requires the recognition of a right-of-use asset and lease liability on the balance sheet for all leases. This standard also requires more detailed disclosures to enable users of financial statements to understand the amount, timing, and uncertainty of cash flows arising from leases. This guidance is effective for interim and annual reporting periods beginning after December 15, 2018 and should be applied through a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, and early adoption is permitted. We expect to adopt this guidance on January 1, 2019. We anticipate this standard will have a material impact on our financial position, primarily due to our office space operating leases, as we will be required to recognize lease assets and lease liabilities on our consolidated balance sheet. We continue to assess the potential impacts of this standard, including the impact the adoption of this guidance will have on our results of operations or cash flows, if any. Information about our undiscounted future lease payments and the timing of those payments is included in Note 9, “Commitments and Contingencies.” 94 In January 2016, the FASB issued guidance on the recognition and measurement of financial instruments. This standard requires equity investments, except those accounted for under the equity method of accounting or those that result in consolidation of the investee, to be measured at fair value with changes in fair value recognized in net income. This standard also requires the separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements. This guidance is effective for interim and annual reporting periods beginning after December 15, 2017, early adoption is permitted, and the guidance must be applied prospectively to equity investments that exist as of the adoption date. We expect to adopt this guidance on January 1, 2018. We have not yet determined our approach to adoption or the impact the adoption of this guidance will have on our financial position, results of operations or cash flows. In November 2015, the FASB issued guidance on the balance sheet classification of deferred taxes. This standard requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. This guidance is effective for interim and annual reporting periods beginning after December 15, 2016, and early adoption is permitted. We adopted this guidance as of January 1, 2016. The adoption of this guidance has no impact on our financial position, results of operations or cash flows. In July 2015, the FASB issued guidance on the measurement of inventory. The amendments require the measurement of inventory at the lower of cost or net realizable value; where net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This guidance is effective for interim and annual reporting periods beginning after December 31, 2016, and early adoption is permitted. We adopted this guidance on January 1, 2017. We do not expect adoption to have a material impact on our financial position, results of operations or cash flows. In August 2014, the FASB issued guidance on the disclosure of uncertainties about an entity’s ability to continue as a going concern. This standard provides guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The guidance is effective for annual reporting periods ending after December 15, 2016, and early adoption is permitted. We adopted this guidance for the year ended December 31, 2016. The adoption had no impact on our financial position, results of operations or cash flows. In May 2014, the FASB issued guidance on revenue recognition. This guidance provides that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The original effective date of this guidance was for interim and annual reporting periods beginning after December 15, 2016, early adoption is not permitted, and the guidance must be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. In July 2015, the FASB approved an optional one-year deferral of the effective date. In 2016, the FASB issued final amendments to clarify the implementation guidance for principal versus agent considerations, identifying performance obligations and the accounting for licenses of intellectual property. We currently expect to adopt the new revenue standards in the first quarter of 2018 utilizing the full retrospective transition method. While we continue to assess all potential impacts of this new standard, we currently do not expect adoption to have a material impact on revenues and the cost of sales commissions. We continue to assess the impact the adoption of this guidance will have on our financial position, results of operations and cash flows. 95 Note 3. Fair Value Measurements Fair Value Measurement Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The standards also establish a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value: • • • Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 2 — Assets and liabilities valued based on observable market data for similar instruments, such as quoted prices for similar assets or liabilities. Level 3 — Unobservable inputs that are supported by little or no market activity; instruments valued based on the best available data, some of which is internally developed, and considers risk premiums that a market participant would require. Our assessment of the significance of a particular input to the fair value measurement requires management to make judgments and consider factors specific to the asset or liability. We applied the following methods and assumptions in estimating our fair value measurements: Cash Equivalents — Cash equivalents are comprised of highly liquid investments, including money market funds and certificates of deposit, with original maturities of less than three months. The fair value measurement of these assets is based on quoted market prices in active markets and these assets are recorded at fair value. Investments — Our investments consist of fixed income securities, which include U.S. government agency securities, corporate notes and bonds and commercial paper. The fair value measurement of these assets is based on observable market-based inputs or inputs that are derived principally from or corroborated by observable market data by correlation or other means. Long-term Debt — The fair values of our long-term debt approximates carrying value based on the borrowing rates currently available to us for loans with similar terms using level 2 inputs. Convertible Preferred Stock Warrants — Our convertible preferred stock contained redemption provisions and therefore our warrants issued to purchase such Series 2 redeemable convertible preferred stock were classified as liabilities and recorded at fair value. These preferred stock warrants were subject to remeasurement at each consolidated balance sheet date and any change in fair value was recognized as a component of other income (expense), net. Upon the effectiveness of the registration statement related to the initial public offering on July 20, 2016, all of our outstanding warrants automatically converted into shares of common stock. At conversion in July 2016, we performed a fair value assessment of the preferred stock warrant liabilities using the Black-Scholes model and the following were the variable input assumptions: Series 2 redeemable convertible preferred stock fair market value of $17.50, Series 2 redeemable convertible preferred stock exercise price of $9.318 per share, remaining contractual lives of the warrants ranging from one to six years, volatility of 50% and risk-free interest rates ranging from 0.5% to 1.3%. Our Series 2 redeemable convertible preferred stock warrant liabilities were categorized as Level 3 because they were valued based on unobservable inputs and our judgment due to the absence of quoted market prices, inherent lack of liquidity and the long-term nature of such financial instruments. At December 31, 2015, we performed a fair value assessment of the preferred stock warrant liabilities using the Black-Scholes model and the following were the variable input assumptions: Series 2 redeemable convertible preferred stock fair market value of $19.20, Series 2 redeemable convertible preferred stock exercise price of $9.318 per share, remaining contractual lives of the warrants ranging from one to seven years, volatility of 50% and risk-free interest rates ranging from 0.6% to 2.1%. The assumptions used in the Black-Scholes model are inherently subjective and involve significant judgment. Any change in fair value is recognized as a component of other income (expense). 96 The following tables present the balances of assets measured at fair value on a recurring basis, by level within the fair value hierarchy, as of December 31, 2016, all such balances as of December 31, 2015 were $0: Cash equivalents: Money market funds U.S. government agency securities Corporate notes and bonds Commercial Paper Short-term investments: U.S. government agency securities Corporate notes and bonds Commercial Paper Total assets measured at fair value LEVEL 1 DECEMBER 31, 2016 LEVEL 2 (in thousands) LEVEL 3 $ $ 14,065 $ — — — — — — 14,065 $ — $ 4,997 959 2,948 36,531 19,252 11,122 75,809 $ — — — — — — — — The following table presents the balances of liabilities measured at fair value on a recurring basis, by level within the fair value hierarchy, as of December 31, 2015, all such balances as of December 31, 2016 were $0: Convertible preferred stock warrants Total liabilities measured at fair value LEVEL 1 DECEMBER 31, 2015 LEVEL 2 (in thousands) LEVEL 3 $ $ — — $ $ — — $ $ 2,865 2,865 The following table provides a roll-forward of the fair value of the preferred stock warrant liabilities categorized as Level 3 for the years ended December 31, 2016 and 2015 (in thousands): Balance at December 31, 2013 Remeasurement of convertible preferred stock warrants Balance at December 31, 2014 Remeasurement of convertible preferred stock warrants Balance at December 31, 2015 Remeasurement of convertible preferred stock warrants Exercise of preferred stock warrants Conversion of preferred stock warrants into common stock warrants at initial public offering Balance at December 31, 2016 97 $ $ $ 3,170 398 3,568 (703) 2,865 (559) (1,801) (505) — Note 4.

The net book value of property and equipment acquired under capital leases was $2.7 million and $3.5 million at December 31, 2016 and 2015, respectively. Note 5. Income Taxes We are subject to income taxes in the U.S. (federal and state) and foreign jurisdictions. In 2016, 2015 and 2014, we recorded tax provisions of $168,000, $166,000 and $96,000, respectively, driven by the amortization of tax goodwill that is not available to be offset by the valuation allowance and income tax expense related to foreign operations. Deferred federal, state and foreign income taxes reflect the net tax impact of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and such amounts for tax purposes. The following table presents the detail of income tax expense as of the periods presented: Current: US - Federal US - State Foreign Deferred: US - Federal US - State Foreign Total income tax expense 2016 YEAR ENDED DECEMBER 31, 2015 (in thousands) 2014 $ $ — $ (15) (63) (78) (91) 1 — (90) (168) $ — $ (56) (22) (78) (88) — — (88) (166) $ — — (5) (5) (91) — — (91) (96) We have not provided for U.S. income taxes and foreign withholding taxes on the undistributed earnings of foreign subsidiaries of $371,000 as of December 31, 2016 as we intend to permanently reinvest such earnings outside the U.S. If these earnings were to be repatriated in the future, the related U.S. tax liability may be reduced by any foreign taxes previously paid on these earnings. The amount of unrecognized deferred tax liability related to these temporary differences is estimated to be approximately $74,000. 98 The following table presents a reconciliation of the federal statutory rate and our effective tax rate for the periods presented: U.S. Statutory Rate Change in valuation allowance State taxes (net of federal benefit) Federal research and development credit Incentive stock options Unrecognized tax benefits Preferred stock warrant revaluation Other, net Effective income tax rate 2016 YEAR ENDED DECEMBER 31, 2015 2014 34.0% (11.8) (4.4) 67.4 (46.2) (47.1) 12.6 (15.5) (11.0)% 34.0% 9.9 3.8 (60.8) 19.5 28.8 (22.4) 2.9 15.7% 34.0% 8.9 (33.6) (136.0) 83.6 34.0 34.4 (1.0) 24.3% The effective tax rate decreased from prior year solely due to the fluctuation in pre-tax book income. Similar to prior years, we continue to be in a full valuation allowance in the US but recognize deferred income tax expense in the US solely based on the amortization of goodwill intangibles. We also record current tax expense for certain state margin taxes that are based on income and on earnings in foreign jurisdictions. The following table presents the significant components of our deferred tax assets and liabilities as of the dates presented: Net operating loss carryforwards (1) (2) Credit carryforwards (2) Depreciation and amortization Capitalized research and development Deferred rent Allowances Deferred compensation Deferred revenue Stock compensation (1) Deferred tax assets Less: Valuation Allowance Net deferred tax assets Deferred Tax Liability: Goodwill Depreciation and Amortization Deferred tax liabilities Net deferred tax liability DECEMBER 31, 2016 2015 (in thousands) $ $ $ $ 34,287 6,492 — 6,992 1,825 767 1,209 331 220 52,123 (50,959) $ 1,164 (766) (1,164) (1,930) (766) $ 33,783 5,693 594 8,164 223 261 760 253 323 50,054 (50,054) — (676) — (676) (676) ____________ (1) During the current period, we recorded an increase to the NOL and an increase to the valuation allowance of $727,000 as a result of the adoption of ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting." (2) Carryforwards are presented net of associated tax contingencies 99 Realization of deferred tax assets is dependent upon the generation of future taxable income, if any, the timing and amount of which are uncertain. We have provided a full valuation allowance against the net deferred tax assets as of December 31, 2016 and 2015 because, based on the weight of available evidence, it is more likely than not (a likelihood of more than 50%) that some or all of the deferred tax assets will not be realized. The valuation allowance increased by $905,000 and $106,000, respectively, during the years ended December 31, 2016 and 2015. We have accumulated federal tax losses of approximately $100.0 million and $97.0 million, respectively, as of December 31, 2016 and 2015, which are available to reduce future taxable income. We have accumulated state tax losses of approximately $779,000 and $794,000 (tax effected), respectively, as of December 31, 2016 and 2015. We did not record a tax benefit related to our stock options during the years ended December 31, 2016 and 2015 due to the full valuation allowance for our deferred tax assets. However, due to the adoption of ASU 2016-09, we recorded an increase to the federal net operating loss of $727,000 and a corresponding increase in the valuation allowance. Additionally, we have net research and development credit carryforwards of $8.5 million and $7.5 million, respectively, as of December 31, 2016 and 2015, which are available to reduce future tax liabilities. The tax loss and research and development credit carryforwards begin to expire in 2023. Under Sections 382 and 383 of the Internal Revenue Code, if a corporation undergoes an ownership change, the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes, such as research tax credits, to offset its post-change income or income tax liability may be limited. We are currently not under audit in any tax jurisdiction. Tax years from 2000 through 2016 are currently open for audit by federal and state taxing authorities. We establish reserves for tax positions based on estimates of whether, and the extent to which, additional taxes will be due. The reserves are established when we believe that positions might be challenged by taxing authorities despite our belief that our tax return positions are fully supportable. The following table presents the total balance of unrecognized tax benefits as of the dates presented: Unrecognized tax benefits at beginning of the period Gross increases to tax positions in prior periods Gross increases to tax positions in current periods Unrecognized tax benefits at end of the period 2016 YEAR ENDED DECEMBER 31, 2015 (in thousands) $ $ 1,878 210 509 2,597 $ $ 1,732 — 146 1,878 $ $ 2014 1,599 — 133 1,732 At December 31, 2016, the total amount of unrecognized tax benefits of $2.6 million is recorded as a reduction to the deferred tax asset. We do not anticipate that the amount of existing unrecognized tax benefits will significantly increase or decrease within the next 12 months. Accrued interest and penalties related to unrecognized tax benefits are recorded as income tax expense and are zero. Note 6. Debt Facilities Senior Credit Facility We have a loan and security agreement, which we refer to as our senior credit facility, with Silicon Valley Bank. The senior credit facility provides for (1) a $10.5 million aggregate principal amount of outstanding term borrowings, (2) revolver borrowings up to the lesser of $15.0 million and a borrowing base tied to the amount of our eligible accounts receivable and inventory, (3) a $5.0 million sublimit under the revolver for the issuance of standby letters of credit and (4) a $2.0 million equipment term-loan facility. 100 In connectio n with the amendment of our senior credit facility in May 2016, we incurred $10.5 million in term borrowings and used such borrowings to refinance $8.2 million in outstanding term borrowings. As amended, interest on term borrowings accrues at a floating ra te equal to the lender’s prime rate plus 2.25% during a one year interest-only period and at a floating rate equal to the lender’s prime rate plus 1.75% after expiration of the interest-only period (6.0% at December 31, 2016). Beginning in June 2017, we mu st begin paying 36 equal monthly installments of principal, plus accrued and unpaid interest. All outstanding principal and accrued and unpaid interest on the term borrowings is due and payable in May 2020. We may at our option prepay the outstanding term loan balance by paying the lender all principal and accrued and unpaid interest, plus a prepayment fee equal to $210,000 if the term-loan is prepaid on or prior to the first anniversary of the May 2016 amendment, and $105,000 if the term loan is prepaid af ter the first anniversary but on or prior to the second anniversary of the May 2016 amendment. At December 31, 2016, we had $10.5 million of term loan borrowings outstanding. Interest on revolver borrowings is payable monthly and accrues at a floating rate equal to the lender’s prime rate plus 2.25% at all times when our cash held at the bank plus the amount available to borrow on the revolver is less than or equal to $8.5 million, and 1.75% when our cash held at the bank plus the amount available to borrow on the revolver is greater than $8.5 million for a period of at least 60 consecutive days (5.5% at December 31, 2016). The maturity date of the revolver is December 2017. At December 31, 2016, we had no revolver borrowings outstanding. As amended in May 2016, our senior credit facility also provides for up to $2.0 million in equipment term loans to fund purchases of eligible equipment. Equipment loans are available for borrowing for one year following the May 2016 amendment date and mature in May 2020. Equipment loans are repaid in 36 equal monthly installments of principal, plus accrued and unpaid interest, following each borrowing and accrue interest at a floating rate equal to the lender’s prime rate plus 1.75% (5.5% at December 31, 2016). We may at our option prepay the outstanding equipment loan balance by paying the lender all outstanding principal and accrued and unpaid interest plus a prepayment fee equal to 2.00% of the principal amount of each equipment loan prepaid if such equipment loan is prepaid on or prior to the first anniversary of the date such equipment loan was borrowed, and 1.00% of the principal amount of each equipment loan prepaid if such equipment loan is prepaid after the first anniversary of the date such equipment loan was borrowed. At December 31, 2016, we had $1.9 million equipment loan borrowings outstanding. At December 31, 2016, $12.4 million of term loan, revolver and equipment loan borrowings were outstanding, excluding unamortized debt issuance costs of $149,000. The weighted average interest rate on these facilities was 5.9% at December 31, 2016. The following table presents the scheduled principal maturities as of December 31, 2016 (in thousands): 2017 2018 2019 2020 $ $ 2,678 4,169 4,109 1,458 12,414 The senior credit facility contains customary conditions to borrowing, events of default and covenants, including covenants that restrict our ability to dispose of assets, merge with or acquire other entities, incur indebtedness, incur encumbrances, make distributions to holders of our capital stock, make investments or engage in transactions with our affiliates. The credit facility also requires us to maintain a minimum tangible net worth and liquidity ratio. We were in compliance with all covenants under our senior credit facility as of December 31, 2016 and December 31, 2015. Substantially all of our assets other than intellectual property are pledged as collateral under the senior credit facility. 101 Mezzanine Credit Facility We had a mezzanine loan and security agreement, which we referred to as our mezzanine credit facility, with SG Enterprises II, LLC, which provided for a $5.0 million term loan which was drawn in September 2015. Interest on the term loan accrued at a fixed per-year rate equal to 18.0% and was payable monthly. On July 26, 2016, we repaid without premium or penalty the principal and accrued interest on the $5.0 million term loan pursuant to the mezzanine credit facility and wrote-off unamortized debt discounts and issuance costs of $109,000. Note 7. Redeemable Convertible Preferred Stock and Stockholders’ Equity (Deficit) Upon the effectiveness of the registration statement related to the initial public offering on July 20, 2016, all of our previously outstanding shares of redeemable convertible preferred stock automatically converted into 8,531,146 of common stock at the conversion rate of 1- to-1 and shares of Series 2 redeemable convertible preferred stock automatically converted into common stock at the conversion ratio of 1-to-1.25. The related carrying value of the redeemable convertible preferred stock of $106.1 million was reclassified to common stock and additional paid-in capital. Our previously outstanding Series 1 and Series 2 preferred stock included certain redemption provisions which prevented us from including these amounts in stockholders’ equity (deficit). Holders of our Series 1 and Series 2 redeemable convertible preferred stock were entitled to accretion equal to 7% annual interest (non-compounded) on the original price paid per share of the applicable series of preferred stock. We recorded accretion of $6.3 million and $11.3 million during 2016 and 2015, respectively, in respect of our outstanding Series 1 and Series 2 redeemable convertible preferred stock. Accretion is generally recorded against distributable earnings. Since we have accumulated losses, we record accretion against additional paid-in capital until there is no remaining capital. Thereafter, accretion is recorded against our accumulated deficit. Common Stock As of December 31, 2016, we had authorized 495,000,000 shares of voting $0.001 par value common stock. Each holder of the common stock is entitled to one vote per common share. At its discretion, the Board of Directors may declare dividends on shares of common stock, subject to the prior rights of our preferred stockholders. Upon liquidation or dissolution, holders of common stock will receive distributions only after preferred stock preferences have been satisfied. As of December 31, 2015, 25,000 common stock warrants were outstanding with an exercise price of $2.52 per share. These common stock warrants were exercised in July 2016. Preferred Stock Warrants The following table presents the preferred stock warrants outstanding, all with exercise prices of $9.318 per share, as of December 31, 2015, all such balances as of December 31, 2016 were $0: Series 2 preferred stock (1) Series 2 preferred stock (1) Series 2 preferred stock (1) Series 2 preferred stock (2) Total Series 2 redeemable convertible preferred stock ISSUANCE DATE SHARES FAIR VALUE AT DECEMBER 31 2015 (in thousands) June 2, 2010 February 1, 2011 July 13, 2012 June 30, 2010 2,004 1,458 41,666 218,523 263,651 $ $ 24 18 548 2,275 2,865 (1) (2) These warrants exercised on a net exercise basis in July 2016. These warrants either were exercised prior to our initial public offering or automatically exercised on a net exercise basis as the per share price of common stock sold to the public in our initial public offering exceeded the exercise price of the warrants. 102 Note 8. Stock-Based Compensation 2016 Equity Incentive Plan In June 2016, our board of directors adopted and our stockholders approved the 2016 Equity Incentive Plan, or the 2016 Plan, which became effective in July 2016 at which time the 2010 Equity Incentive Plan, or the 2010 Plan, was terminated. Our 2000 Stock Plan was terminated in March 2010. Shares of common stock reserved for issuance under the 2016 Plan consist of (a) 1,096,234 shares of common stock initially available for grants under the 2016 Plan, plus (b) 674,790 shares of common stock previously reserved but unissued and not subject to outstanding awards under the 2010 Plan that are now available for issuance under the 2016 Plan. The number of shares of common stock reserved for issuance under the 2016 Plan may increase on January 1 of each year, beginning on January 1, 2017 and ending on and including January 1, 2026, by the lesser of (1) 1,825,000; (2) 5% of the total number of shares of common stock outstanding on December 31 of the preceding calendar year; or (3) a lesser number of shares determined by our board of directors. All options granted under the 2000 Stock Plan, the 2010 Plan and the 2016 Plan have a maximum 10-year term and generally vest and become exercisable over four years of continued employment or service as defined in each option agreement. We generally grant stock options with exercise prices that equal the fair value of the common stock on the date of grant. As of December 31, 2016, we have reserved 3,536,156 shares of common stock for issuance under our stock option plans. Prior to the adoption of our 2016 Equity Incentive Plan, we provided employees with the opportunity to early exercise stock options subject to the original vesting schedule of the option. In the event of voluntary or involuntary termination of employment with us, we have an irrevocable and exclusive option to repurchase the unvested portion of the shares at the original exercise price after the termination of employment. We account for cash received in consideration for the purchase of unvested shares of common stock or the early exercise of unvested stock options as a current liability and include it in accrued compensation and employee related benefits on the consolidated balance sheet. We repurchased 0 and 2,020 unvested shares from terminated employees in 2016 and 2015, respectively. The following table summarizes activity of unvested shares of our common stock for the year ended December 31, 2016: Outstanding at January 1, 2016 Issued Vested Outstanding at December 31, 2016 103 SHARES OUTSTANDING NUMBER OF SHARES WEIGHTED- AVERAGE EXERCISE PRICE PER SHARE (in thousands, except per share amounts) $ 136 59 (77) $ 118 1.76 5.35 2.15 3.30 The following table summarizes option award activity for the year ended December 31, 2016: NUMBER OF SHARES UNDERLYING OPTIONS WEIGHTED- AVERAGE WEIGHTED- AVERAGE EXERCISE PRICE PER SHARE REMAINING CONTRACTUAL LIFE (YEARS) (in thousands, except per share amounts) TOTAL INTRINSIC VALUE Outstanding at January 1, 2016 Granted Exercised Forfeited or cancelled Outstanding at December 31, 2016 Vested and exercisable December 31, 2016 $ 1,896 707 (196) (97) 2,310 1,067 $ 3.72 20.59 3.05 6.28 8.84 2.69 7.77 $ 8,666 7.68 6.15 $ 61,203 34,831 We estimate the weighted-average fair value of options granted during 2016, 2015 and 2014, some with exercise prices less than the estimated per share value of our common stock for financial reporting purposes on the grant date, was $9.60, $3.12 and $4.08 per share, respectively. The total intrinsic value of options exercised during 2016, 2015 and 2014 was $1.1 million, $3.8 million and $1.9 million, respectively. The total fair value of options vested was $1.4 million, $1.3 million and $1.8 million during 2016, 2015 and 2014, respectively. As of December 31, 2016, our total unrecognized stock-based compensation cost related to stock options was $8.6 million, which will be recognized over the weighted-average remaining requisite service period of 2.9 years. Employee Stock Purchase Plan In 2016, we adopted the 2016 Employee Stock Purchas e Plan, the ESPP, which became effective in July 2016. Under the ESPP, eligible employees can authorize payroll deductions for amounts up to 15% of their eligible compensation. A participant may purchase a maximum of 4,000 shares each six-month period or some lesser number of shares as determined by IRS rules. The offering periods generally start on the first trading day on or after February 20 and August 20 of each year, except for the first offering period, which commenced on July 21, 2016 and will end on the first trading day on or after February 20, 2017. Participants in an offering period will be granted the right to purchase common shares at a price per share that is 85% of the least of the fair market value of the shares at (1) the first day of the offering period and (2) the end of each purchase period within the offering period. The fair value of the ESPP options granted is determined using a Black-Scholes model and is amortized on a straight-line basis. The initial number of shares of common stock that may be issued under the ESPP was 365,411 and as of December 31, 2016 were reserved for future grants under the ESPP. The number of shares reserved for the ESPP may increase each year, beginning on January 1, 2017 and continuing through and including January 1, 2036, by the least of (1) 1% of the total number of shares of common stock outstanding on the first day of such year; (2) 365,411 shares of common stock; and (3) such amount as determined by our board of directors. As of December 31, 2016, the total unrecognized stock-based compensation related to the ESPP was $335,000 and will be recognized on a straight-line basis over the weight-average remaining service period of 0.1 years . 104 Black-Scholes Option Pricing Model In determining the fair value of stock awards granted, the following weighted-average assumptions were used in the Black-Scholes option pricing model for awards granted in the periods indicated: Risk-free interest rates Expected term Expected dividends yield Volatility EMPLOYEE STOCK PURCHASE PLAN YEAR ENDED DECEMBER 31, 2016 0.4% 0.5 years None 61.8% 2016 1.1% – 1.4% 4.3 – 6.1 years None STOCK OPTIONS YEAR ENDED DECEMBER 31, 2015 1.2% – 1.6% 4.3 – 6.0 years None 40.8% – 49.5% 41.5% – 43.4% 2014 1.8% – 2.0% 6.0 years None 43.8% – 46.9% We determined that it was not practicable to calculate the volatility of our share price since we do not have an extensive public trading history for shares of our common stock . Therefore, we estimated our volatility based on a combination of our historical volatility since becoming a publicly traded company and reported market value data for a group of publicly-traded entities that we believe are relatively comparable after consideration of their size, stage of lifecycle, profitability, growth and risk and return on investment. We used a smaller weighting of our historical volatility since becoming a publicly traded company and the average volatility rates reported by the comparable group for the expected term estimated by us. Stock-Based Compensation Expense The following table presents the detail of stock-based compensation expense amounts included in our consolidated statements of operations for the periods indicated: Cost of revenue Research and development expense Sales and marketing expense General and administrative expense Offering costs Total stock-based compensation expense Note 9.

The terms of the lease provide for rental payments on a graduated scale and the right to terminate this lease beginning in December 2022, subject to the payment of certain early termination fees. We received landlord incentives totaling $4.7 million which we recorded as deferred rent obligations and are amortizing as a reduction in rental expense over the remaining term of the lease. As part of the lease amendment in May 2016 for approximately 18,000 square feet of additional office space, we will receive in 2017 landlord incentives totaling $1.7 million to offset the costs of leasehold improvements. We lease approximately 11,000 square feet of space in Seattle for a design laboratory under an operating lease that expires in October 2018 with an option to renew for an additional one or three year term. The terms of the lease provide for rental payments on a graduated scale and the right to terminate this lease early, beginning in December 2015, subject to the payment of certain early termination fees. We received landlord incentives of $108,000 and have used $95,000. We recorded these incentives as deferred rent obligations and are amortizing them as a reduction in rental expense over the term of the lease. 105 We recognize rent expense on a stra ight-line basis over the lease period. Total rent expense under operating leases was $2.9 million and $1.1 million for the years ended December 31, 2016 and 2015, respectively. We lease a portion of our property and equipment under capital leases, which include options allowing us to purchase the equipment at the end of the lease term. The following table presents future minimum lease payments under operating and capital leases as of December 31, 2016 were as follows: OPERATING CAPITAL 2017 2018 2019 2020 2021 Thereafter Total minimum lease payments Less: Portion representing interest Present value of capital lease obligations Less: Current portion of capital lease obligations Capital lease obligations net of current portion $ $ $ (in thousands) 3,096 3,029 2,900 2,984 3,069 16,603 31,681 $ $ 1,330 1,038 574 261 — — 3,203 (375) 2,828 (1,130) 1,698 In the normal course of business, we periodically enter into agreements that require us to indemnify either major customers or suppliers for specific risks. While our maximum exposure under these indemnification provisions cannot be estimated, these indemnifications are not expected to have a material impact on our consolidated results of operations or financial condition. Obligations with Third-Party Manufacturers We manufacture products with a third-party manufacturer under recurring one year agreements. We are committed to purchase $14.1 million of inventory as of December 31, 2016. Note 10. Segment Reporting Operating segments are defined as components of an enterprise for which separate financial information is available and evaluated regularly by the chief operating decision-maker, or decision-making group, in deciding how to allocate resources and in assessing performance. We are organized as, and operate in, one reportable segment: the development and sale of Item Intelligence products and services. Our chief operating decision- maker is the executive team, led by our chief executive officer. Our executive team regularly reviews financial information presented on a total company basis, accompanied by information about revenue and direct material gross margin by product family for purposes of monitoring our product mix impact on total gross margin. Our executive team evaluates performance based primarily on total revenue as end users are generally deploying many of our products and services to obtain the benefits of our integrated platform in the implementation of an Item Intelligence solution. Our assets are primarily located in the United States and not allocated to any specific geographic region. Therefore, geographic information is presented only for total revenue. Substantially all of our long-lived assets are located in the United States. 106 The following table is based on the location of the value-added resellers, inlay manufacturers, reader OEMs, distributors or end users who purch ased products and services directly from us. For sales to our resellers and distributors, their location may be different from the locations of the ultimate end users. Sales by geography were as follows: Americas Asia Pacific Europe, Middle East and Africa Total Revenue 2016 $ $ 26,401 73,084 12,802 112,287 $ $ YEAR ENDED DECEMBER 31, 2015 (in thousands) 21,568 45,096 11,815 78,479 $ $ 2014 21,738 33,898 8,127 63,763 Total revenue in the United States was $25.9 million, $21.0 million and $19.6 million for the years ended December 31, 2016, 2015 and 2014, respectively. Note 11. Retirement Plans In 2001, we adopted a salary deferral 401(k) plan for our employees. The plan allows employees to contribute a percentage of their pretax earnings annually, subject to limitations imposed by the Internal Revenue Service. The plan also allows us to make a matching contribution, subject to certain limitations. To date, we have not made any contributions to the plan. 107 Item 9. Changes in and Disagreements with Acco untants on Accounting and Financial Disclosure None. Item 9A. Controls and Procedures Evaluation of Disclosure Controls and Procedures Our management, with the participation of our chief executive officer and our chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2016. Disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is (1) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (2) accumulated and communicated to management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation of our disclosure controls and procedures, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were effective as of December 31, 2016 at a reasonable assurance level . Management’s Report on Internal Control Over Financial Reporting This report does not include a report of management’s assessment regarding internal control over financial reporting or an attestation report of our independent registered public accounting firm due to a transition period established by rules of the SEC for newly public companies. Previously Identified Material Weakness in Internal Control Over Financial Reporting We previously identified and disclosed in our Registration Statement on Form S-1 for the period ended December 31, 2015, as well as in our Quarterly Reports on Form 10-Q for each interim period in fiscal year 2016, a material weakness in our internal control over financial reporting relating to the accounting and financial statement disclosure over complex accounting matters. The impact of this material weakness resulted in the restatement of our consolidated financial statements for the years ended December 31, 2012 and 2013. The impact of this material weakness also resulted in the restatement of our consolidated financial statements for the three and nine months ended September 30, 2015 and 2016. Remediation Efforts to Address Previously Disclosed Material Weakness Our management, with oversight from our audit committee, has taken steps to implement the following remediation actions to address the previously disclosed material weakness and to improve our internal control over financial reporting, primarily through: • • • increasing the depth and experience within our accounting and finance organization; enhancing the communication and coordination among our accounting and financial reporting department and expanded cross-functional involvement and input into period-end disclosures; and implementing additional internal reporting procedures, including enhancing the analytical procedures used to assess period-end balances, to add depth to our review process and improve our segregation of duties. During the quarter ended December 31, 2016, we continued to assess the design of existing controls and implement new controls as needed to remediate the previously identified material weakness. We have yet to complete the testing and evaluation of the operating effectiveness of controls, and the previously disclosed material weakness remained unremediated as of the quarter ended December 31, 2016. 108 Changes in Internal Control over Financial Reporting There were no changes in our internal control over financial reporting identified during the three months ended December 31, 2016 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Limitations on Controls Our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving the desired control objectives. Our management recognizes that any control system, no matter how well designed and operated, is based upon certain judgments and assumptions and cannot provide absolute assurance that its objectives will be met. Similarly, an evaluation of controls cannot provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected.
