BusinessOverviewExtreme Networks, Inc., together with its subsidiaries (collectively referred to as “Extreme” and as “we”, “us” and “our”) is a leader in providingsoftware-driven networking solutions for enterprise customers. Providing a combined end-to-end solution from the data center to the access point, Extremedesigns and develops wired and wireless network infrastructure equipment and develops the software for network management, policy, analytics, security andaccess controls. We strive to help our customers and partners Connect Beyond the Network by building world-class software and network infrastructuresolutions that solve the wide range of problems faced by information technology (“IT”) departments. With more than 30,000 customers globally, includinghalf of the Fortune 50 and some of the world's leading names in business, hospitality, retail, transportation and logistics, education, government, healthcareand manufacturing, we remain nimble and responsive to ensure customer and partner success. We call this Customer-Driven Networking™.During fiscal year 2018, Extreme experienced a 62% year-over-year revenue growth. These results reflect continued execution toward our strategicobjectives, including results from the recently acquired fabric-based secure networking solutions and network security solutions business (the “CampusFabric Business”) from Avaya Inc. (“Avaya”) and the data center business (the “Data Center Business”) of Brocade Communication Systems, Inc.(“Brocade”). Fiscal year 2018 year-over-year revenue growth also includes a full year contribution from the wireless local area network (“WLAN”) business(the “WLAN Business”) from Zebra Technologies Corporation (“Zebra”) that was acquired in October 2016.Enterprise network administrators from the data center to the access layer need to respond to the rapid digital transformational trends of cloud,mobility, big data, social business and the ever-present need for network security. Accelerators such as Internet of Things (“IoT”), artificial intelligence(“AI”), bring your own device (“BYOD”), machine learning (“ML”), cognitive computing, and robotics add complexity to challenge the capabilities oftraditional networks. Technology advances have a profound effect across the entire enterprise network by placing unprecedented demands on networkadministrators to enhance management capabilities, scalability, programmability, agility, security, and analytics of the enterprise networks they manage.Improving the network experience for enterprises that increasingly require greater simplification at the edge or the access layer of the network toensure business success and provide a secure, unified, wired / wireless infrastructure augmented and managed through a single plane of glass remains a keyfocus with the introduction of our Smart OmniEdge product portfolio with the launch of ExtremeAI and Project Surge to simplify IoT security. Enterpriseshave also migrated increasing numbers of applications and services to either private clouds or public clouds offered by third parties and are adopting new ITdelivery models and applications that require fundamental network alterations and enhancements spanning from device access point to the network core. Ineither case, the network infrastructure must adapt to this new dynamic environment. Intelligence and automation are key if enterprises are to derive maximumbenefit from their cloud deployments.A trend affecting the enterprise network equipment market is the continued adoption of the cloud-managed enterprise WLAN in the enterprise market.Hybrid cloud is a cloud computing environment which uses a mix of on-premise private cloud and third-party public cloud services with orchestrationbetween the two platforms. We introduced ExtremeCloud, our Cloud offering in 2016 and announced our enhanced cloud offering in 2017. ExtremeCloud isthe only offering in the market that seamlessly integrates the Cloud with on premise infrastructures.2 To facilitate the readers understanding, the following is a list of common terms in our industry used in the discussion of our business: •Internet Protocol: Internet Protocol (“IP”) is the principal set (or communications protocol) of digital message formats and rules for exchangingmessages between computers across a single network or a series of interconnected networks, using the Internet Protocol Suite (often referred to asTCP/IP) •Access Point: A wireless access point, or more generally just access point (“AP”), is a networking hardware device that allows a Wi-Fi device toconnect to a wired network. (Industry term) •OpenFlow: OpenFlow (“OF”) is considered one of the first software-defined networking (“SDN”) standards. It originally defined thecommunication protocol in SDN environments that enables the SDN Controller to directly interact with the forwarding plane of network devicessuch as switches and routers, both physical and virtual (hypervisor-based), so it can better adapt to changing business requirements. (Source: SDxCentral) •OpenStack: OpenStack software controls large pools of compute, storage, and networking resources throughout a datacenter, managed through adashboard or via the OpenStack API. OpenStack works with popular enterprise and open source technologies making it ideal for heterogeneousinfrastructure. (Source: OpenStack.org) •CloudStack: CloudStack is an open source cloud computing software for creating, managing, and deploying infrastructure cloud services. It usesexisting hypervisors such as KVM, VMware ESXi and XenServer/XCP for virtualization. •Single Pane of Glass: Single pane of glass is a term used to describe a management display console that integrates all parts of a computerinfrastructure. •Fabric Attach: Avaya’s Fabric Attach (“FA”) fundamentally introduces autonomic/automatic attachment to network services for end users IoTdevices to a network infrastructure. Fabric Attach and Fabric Connect are key building blocks of the Avaya SDN Fx™ architecture. •Fabric Connect: Fabric Connect is an extended implementation of the IEEE/IEFT standards for Shortest Path Bridging (“SPB”). It offers a full-service network virtualization technology that combines the best of Ethernet and the best of IP. •Campus (Network): A campus network, or campus area network, or corporate area network (“CAN”) is a computer network made up of aninterconnection of local area networks (“LANs”) within a limited geographical area, such as a college campus, company campus, hospital, hotel,convention center or sports venue. •Data Center: A data center is a facility used to house computer systems and associated components, such as telecommunications and storagesystems. It generally includes redundant or backup power supplies, redundant data communications connections, environmental controls (e.g. airconditioning, fire suppression) and various security devices. •Data Center Fabric technologies: Also known as networking switch fabric, is the basic topology of how a network is laid out and connected toswitch traffic on a data or circuit-switched network. •Stackstorm: A platform for integration and automation across services and tools. It ties existing infrastructure and application environment toautomate that environment. It has a particular focus on taking actions in response to events. •Artificial Intelligence: Artificial Intelligence (“AI”) is a set of technologies that enable computers to simulate the cognitive knowledge-processingcapabilities of humans. Because it is artificial, the objective of most work in AI is to augment the capabilities of humans, not to replace them. Justas computers in general are applied to the tedious and repetitive tasks that humans find tedious, AI-based solutions can deal with often large (“BigData”) volumes of digitally-encoded information dispassionately, unemotionally, rapidly, and, depending upon the parameters of a specificapplication and implementation, accurately. In network administration, AI can be applied to dealing with the “more-variables-than-equationsnature” of radio frequency settings in even very- large-scale Wi-Fi installations. The goal is to achieve optimal network-wide performance moreaccurately and at lower cost than would be possible with humans alone. •Machine Learning: Machine Learning (“ML”) is a set of technologies, and itself a branch of AI, that enables computers to simulate humanlearning, with learning defined here as the ability to change behavior and/or essential capabilities (again, simulated as a digital process on acomputer) in response to new information suitably encoded for consumption by the algorithms implementing ML. In other words, ML enables AI-based processes to “learn” from past behaviors and consequently to improve future results, in much the same way as experiential education benefitshumans. •Wi-Fi: Wireless Access points using Radio Frequency and protocols to allow computers, smartphones, or other devices to connect to the Internet orcommunicate with one another wirelessly within an area.3 •Network Automation: Network Automation (“NA”) is a methodology in which software automatically configures, provisions, manages and testsnetwork devices. It is used by enterprises and service providers to improve efficiency and reduce human error and operating expenses. •Edge: An edge device is a device which provides an entry point into enterprise or service provider core networks. Examples include routers,routing switches, integrated access devices (“IADs”), multiplexers, and a variety of metropolitan area network (“MAN”) and wide area network(“WAN”) access devices. •Access: Network access is the closest point of entry to a network whether it is a wireless access point, Ethernet connection, or Wi-Fi device. •Aggregation: In computer networking, the term aggregation applies to various methods of combining (aggregating) multiple network connectionsin parallel in order to increase throughput beyond what a single connection could sustain, and to provide redundancy in case one of the linksshould fail. •Core: A core network, or network core, is the central part of a telecommunications network that provides various services to customers who areconnected by the access network. •Layer 3 Data Center Interconnect; A Data Center Interconnect (“DCI”) refers to the networking of two or more different data centers to achievebusiness or IT objectives. This interconnectivity between separate data centers enables them to work together, share resources and/or passworkloads between one another. A Layer 3 DCI refers to interconnection made through layer 3 of the commonly-referenced multilayeredcommunication model, Open Systems Interconnection (“OSI”). •Flipped Classroom: Flipped classroom is an instructional strategy and a type of blended learning that reverses the traditional learningenvironment by delivering instructional content, often online, outside of the classroom. Industry BackgroundEnterprises are adopting new IT delivery models and applications that require fundamental network alterations and enhancements spanning fromdevice access point to the network core. AI and ML technologies have the potential to vastly improve the network experience. When AI and ML are used inconjunction with an NA technology, administrators can make significant advances in productivity, availability, accessibility, manageability, security andspeed of their network infrastructure. These emerging technologies are driving administrators to a mindset of change toward agile processes that allow aversatile workforce to improve the rate of innovation of the enterprise safely, securely and with confidence.AI, ML and NA have increased the relevance and importance of the network in the enterprise. Traditional network offerings are not well-suited tofulfill enterprise expectations for rapid delivery of new services, more flexible business models, real-time response and massive scalability. The networking industry appears to be invigorated by this wave of technological change: •Ethernet (wired and wireless) has solidified its role in both public and private networks through its scalability, adaptability and cost-effectiveness. At the same time, the enterprises and service providers expect the technology to follow a price-performance curve that mandatescontinued innovation by Ethernet vendors. •The mobile workforce continues to proliferate. Employees expect high-quality and secure access to corporate resources in a BYOD world across adiversity of endpoints such as laptops, tablets, smart phones and wearables, whether they are within the corporate firewall or on-the-go. WithExtremeManagement, IT departments focus their investment decisions on this mobile workforce, taking a unified view of wireless access, from thecampus core and the data center. Extreme offers end-to-end solutions that permit IT managers to meet employee expectations and to maximize ITreturn on investment. •Verticals such as retail, finance, healthcare, education, manufacturing, government and hospitality (which includes sports and entertainmentvenues) are connecting with their customers and guests beyond the network. These enterprises are investing in guest and location technologiesthat connect with their customers via their mobile devices over their WLAN. This allows them to obtain rich analytics for contextual marketing,which in turn, enables them to deliver a personalized brand experience. ExtremeGuest and ExtremeLocation have been built on cloud-basedtechnology for simple implementation and fast release to market to better provide necessary insights into guest demographics and location-basedanalytics.4 •The Internet of Things. The Internet of Things is having dramatic effects on network infrastructure in healthcare, education, manufacturing,government and retail as more “smart” devices are entering the networks. These devices pose opportunities as well as threats to the network. •Growing usage of the cloud. Enterprises have migrated increasing numbers of applications and services to either private clouds or public cloudsoffered by third parties. In either case, the network infrastructure must adapt to this new dynamic environment. Intelligence and automation arekey if enterprises are to derive maximum benefit from their cloud deployments. Ethernet speeds, scaling from 10 Gigabits per second ("G") to 100G,provide the infrastructure for both private and public clouds. In addition, there is growing interest in SDN approaches that may includetechnologies such as OpenFlow, OpenStack, and CloudStack for increased network agility. •Vendor consolidation is expected to continue. Consolidation of vendors within the enterprise network equipment market and between adjacentmarkets (storage, security, wireless & voice software and applications) continues to gain momentum. We identified this trend in 2013 with ouracquisition of Enterasys. Further, we believe customers are demanding more end-to-end, integrated networking solutions. To address this demand,we acquired the WLAN Business of Zebra in October 2016, the Campus Fabric Business from Avaya in July 2017, and the Data Center Businessfrom Brocade in October 2017.Our strategy, product portfolio and research and development are closely aligned with what we have identified as the following trends in ourindustry: ○The software segment of the worldwide enterprise network equipment market has continued to evolve and demands for improvements inNetwork Management will continue. ➣We announced our Extreme Management Console in Fiscal 2017. This innovative software helps IT network administrators tonavigate the unprecedented demands caused by the surge of IoT devices and technology. ○Enterprise adoption of the cloud and open-source options are disrupting traditional license and maintenance business models. ➣We announced cloud offerings in April 2016 and enhanced those offerings in 2017. Extreme began participation in the OpenSwitchprogram in May 2016 and now participates in the StackStorm community with the acquisition from Brocade in November 2017. oEnterprise adoption of new financing solutions allows for increased flexibility, Limited investment and zero long-termcommitments. These offerings are changing the traditional CAPEX model to (OPEX) models using financing purchases over time aredisrupting traditional sell-in business models. ➣We announced Extreme Capital Solutions in April 2018. The offering includes subscription, capital leasing and usage business modelsthat provide flexibility for partners and customers. ○Growth of wireless devices continues to outpace hardwire switch growth. ➣We announced our 802.11ac Wave 2 wireless offering in late 2015 and plans to continue to advance our wireless portfolio of indoorand outdoor access points.The Extreme StrategyWe are focused on delivering end-to-end IP networking solutions for today’s enterprise environments.

Their networks must be highly available with the ability to continue operationsin the event of a service interruption. Secure access is essential to ensuring the protection of mission-critical systems and confidential information.Often tasked to manage the network with a limited IT staff, our customers appreciate the excellent service and support we strive to provide.Customers with 10% of net revenue or greaterThe following table sets forth major customers accounting for 10% or more of our net revenue: Year Ended June 30,2018 June 30,2017 June 30,2016 (As adjusted*) (As adjusted*) Tech Data Corporation 14% 16% 17% Jenne Corporation 13% 15% 14% Westcon Group Inc. 13% 12% 13% *The above summary table of our major customers accounting for 10% or more of our net revenue for the years ended June 30, 2018, 2017, and 2016reflects the adoption of Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“Topic 606”).International salesInternational sales are an important portion of our business. In fiscal 2018, sales to customers outside of the United States accounted for 50% of ourconsolidated net revenues, compared to 49% in fiscal 2017 and 55% in fiscal 2016. These sales are conducted primarily through foreign-based distributorsand resellers managed by our worldwide sales organization. In addition, we have direct sales to end-user customers, including large global accounts. Theprimary markets for sales outside of the United States are countries in Europe and Asia, as well as Canada, Mexico, Central America and South America.We operate in one segment, the development and marketing of network infrastructure equipment. Information concerning revenue, results ofoperations and revenue by geographic area is set forth under Item 7, “Management's Discussion and Analysis of Financial Condition and Results ofOperations,” and in Note 3 of our Notes to Consolidated Financial Statements in this Annual Report on Form 10-K, both of which are incorporated herein byreference. Information on risks attendant to our foreign operations is set forth below in Item 1A. “Risk Factors.”MarketingWe continue to develop and execute on a number of marketing programs to support the sale and distribution of our products by communicating thevalue of our solutions to our existing and potential customers, our distribution channels, our resellers and our technology alliance partners. Our marketingefforts include participation in industry tradeshows, conferences and seminars, publication of technical and educational articles in industry journals,communication across social media channels, frequent updates to our publicly available website, promotions, web-based training courses, advertising,analyst relations and public relations. We also submit our products for independent product testing and evaluation. Extreme participates in numerousindustry analyst ratings including Gartner Magic Quadrants, Gartner Critical Capabilities, Gartner Peer Insights, Forrester Waves, IDC MarketScapes andInfoTech Vendor Landscapes.14 BacklogOur products are often sold on the basis of standard purchase orders that are cancelable prior to shipment without significant penalties. In addition,purchase orders are subject to changes in quantities of products and delivery schedules in order to reflect changes in customer requirements andmanufacturing capacity. Our business is characterized by seasonal variability in demand and short lead-time orders and delivery schedules. Actual shipmentsdepend on the then-current capacity of our contract manufacturers and the availability of materials and components from our vendors. Although we believethe orders included in the backlog are firm, all orders are subject to possible rescheduling by customers, cancellations by customers which we may elect toallow without penalty to customer, and further pricing adjustments on orders from distributors. Therefore, we do not believe our backlog, as of any particulardate is necessarily indicative of actual revenue for any future period.Our product backlog at June 30, 2018, net of anticipated back end rebates for distributor sales, was $42.5 million, compared to $25.5 million atJune 30, 2017.SeasonalityLike many of our competitors, we historically have experienced seasonal fluctuations in customer spending patterns, which generally adversely affectour first and third fiscal quarters. This pattern should not be relied upon or be considered indicative of our future performance, however, as it has varied in thepast.Customer Service and SupportOur customers seek high reliability and maximum uptime for their networks. To that extent, we provide the following service offerings: •Support services for end-users, resellers and distributors. We meet the service requirements of our customers and channel partners through ourTechnical Assistance Centers ("TACs"), located in Morrisville, North Carolina; Salem, New Hampshire; Holtsville, New York; San Jose, California;Reading, United Kingdom; Penang, Malaysia; Brno, Czech Republic; Utrect, Netherlands; Bangalore and Chennai, India. Our TAC engineers andtechnicians assist in diagnosing and troubleshooting technical issues regarding customer networks. Development engineers work with the TACs toresolve product functionality issues specific to each customer. •Professional services. We provide consultative services to improve customer productivity in all phases of the network lifecycle – planning, design,implementation, operations and optimization management. Our network architects develop and execute customized software and service-lednetworking solutions for deployment plans to meet individualized network strategies. These activities may include the management andcoordination of the design and network configuration, resource planning, staging, logistics, migration and deployment. We also providecustomized training and operational best practices manuals to assist customers in the transition and sustenance of their networks. •Education. We offer classes covering a wide range of topics such as installation, configuration, operation, management and optimization –providing customers with the necessary knowledge and experience to successfully deploy and manage our products in various networkingenvironments. Classes may be scheduled and available at numerous locations worldwide. We deliver training using our staff, on-line trainingclasses and authorized training partners. In addition, we make much of our training materials accessible free-of-charge on our internet site forcustomers and partners to use in self-education. We believe this approach enhances the market’s ability to learn and understand the broad array ofadvantages of our products.Long-Lived AssetsSee Note 5 of our Notes to Consolidated Financial Statements in this Annual Report on Form 10-K for more information regarding our long-livedassets.ManufacturingWe utilize a global sourcing strategy that emphasizes procurement of materials and product manufacturing in lower cost regions. We rely upon third-party contract manufactures and original design manufacturers (Alpha Networks, Delta Networks Inc, Foxconn, Senao Networks and Wistron NeWebCorporation) to manufacture, support and ship our products, and therefore are exposed to risks associated with their businesses, financial condition and thegeographies in which they operate. Our arrangements with these manufacturers generally provide for quality, cost, and delivery requirements, as well asmanufacturing process terms, such as continuity of supply; inventory management; flexibility regarding capacity, quality, and cost management; oversightof manufacturing; and conditions for use of our intellectual property that allows us to adjust more quickly to changing end-customer demand. Themanufacturing process uses automated testing equipment and burn-in procedures, as well as comprehensive inspection, testing, and statistical processcontrols, which are designed to help ensure the quality and reliability of our products. The manufacturing processes and procedures are generally certified toInternational Organization for Standardization (“ISO”) 9001 standards. 15 We use a collaborative sales and operations planning (“S&OP”) forecast of expected demand based upon historical trends and analyses from our salesand product management functions as adjusted for overall market conditions. We update these forecasts monthly to determine our material requirements. Ourmanufacturing partners procure the majority of the components needed to build our products based on our demand forecasts. This allows us to leverage thepurchasing power of our manufacturing partners. Our products rely on key components, including merchant silicon, integrated circuit components and powersupplies purchased from a limited number of suppliers, including certain sole source providers. Lead times for materials and components vary significantly,and depend on factors such as the specific supplier, contract terms and demand for a component at a given time. From time to time, we may experiencesignificant price volatility or supply constraints for certain components that are not available from multiple sources or where our suppliers are geographicallyconcentrated. When necessary, we are often able to obtain scarce components for somewhat higher prices on the open market, which may have an impact onour gross margin, but does not generally disrupt production. We may also acquire component inventory in anticipation of supply constraints, or enter intolonger-term pricing commitments with vendors to improve the priority, price and availability of supply. Our product development efforts also depend uponcontinued collaboration with our key suppliers, including our merchant silicon vendors such as Broadcom. As we develop our product roadmap and continueto expand our relationships with these and other merchant silicon vendors, it is critical that we work in tandem with our key merchant silicon vendors toensure that their silicon includes improved features and that our products take advantage of such improved features.We believe that our sourcing and manufacturing strategy allows us to conserve capital, lower costs of product sales, adjust quickly to changes inmarket demand, and operate without dedicating significant resources to manufacturing-related plant and equipment. As part of our effort to optimize ouroperations, we continue to focus on driving cost reductions through sourcing, rationalizing our supply chain, outsourcing or virtualizing certain activities,and consolidating distribution sites and service logistics partners. These efforts also include process optimization initiatives, such as vendor managedinventory, and other operational models and strategies designed to drive improved efficiencies in our sourcing, production, logistics and fulfillment.Research and DevelopmentThe success of our products to date is due in large part to our focus on research and development. We believe that continued success in themarketplace will depend on our ability to develop new and enhanced products employing leading-edge technology. Accordingly, we plan to undertakedevelopment efforts with an emphasis on increasing the reliability, performance and features of our family of products, and designing innovative products toreduce the overall network operating costs of customers.Our product development activities focus on solving the needs of customers in the enterprise campus by providing an end-to-end, wired and wirelessnetwork solution from the access edge to the private clouds in targeted verticals. Current activities include the continuing development of our innovativeswitching technology aimed at extending the capabilities of our products. Our ongoing research activities cover a broad range of areas, including, 1G, 2.5G,5G, 20G, 25G, 40G, 50G and 100G Ethernet, routing, timing and resiliency protocols, open standards interfaces, software defined networks, network security,identity management, data center fabrics, and wireless networking.We plan to continue to enhance the functionality of our modular operating systems which have been designed to provide high reliability andavailability. This allows us to leverage a common operating system across different hardware and network chipsets.As of June 30, 2018, our research and development organization consisted of 999 employees. Research and development efforts are conducted inseveral of our locations, including San Jose, California, Morrisville, North Carolina; Salem, New Hampshire; Toronto, Canada, and Bangalore and Chennai,India. Our research and development expenses in fiscal years 2018, 2017 and 2016 were $183.9 million, $93.7 million and $78.7 million, respectively.Intellectual PropertyWe rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual propertyrights. As of June 30, 2018, we had 620 issued patents in the United States and 88 patents outside of the United States. The expiration dates of our issuedpatents in the United States range from 2018 to 2035. Although we have patent applications pending, there can be no assurance that patents will be issuedfrom pending applications or that claims allowed on any future patents will be sufficiently broad to protect our technology. As of June 30, 2018, we had 20registered trademarks in the United States and 113 registered trademarks outside of the United States.We enter into confidentiality, inventions assignment or license agreements with our employees, consultants and other third parties with whom we dobusiness, and control access to, and distribution of, our software, documentation and other proprietary information. In addition, we provide our softwareproducts to end-user customers primarily under “shrink-wrap” or "click-through" license agreements. These agreements are not negotiated with or signed bythe licensee, and thus these agreements may not be enforceable in some jurisdictions. Despite our efforts to protect our proprietary rights, unauthorizedparties may attempt to copy or otherwise obtain and use our products or technology, particularly in foreign countries where the laws may not protect ourproprietary rights as fully as in the United States.16 CompetitionThe market for network switches, routers and software (including analytics) which is part of the broader market for networking equipment is extremelycompetitive and characterized by rapid technological progress, frequent new product introductions, changes in customer requirements and evolving industrystandards. We believe the principal competitive factors in this market are: •expertise and familiarity with network protocols, network switching/routing/wireless and network management; •expertise and familiarity with application analytics software; •expertise with network operations and management software; •expertise in machine learning and artificial intelligence; •product performance, features, functionality and reliability; •price/performance characteristics; •timeliness of new product introductions; •adoption of emerging industry standards; •customer service and support; •size and scope of distribution network; •brand name; •breadth of product offering; •access to customers; and •size of installed customer base.We believe we compete with our competitors with respect to many of the foregoing factors. However, the market for network switching solutions isdominated by a few large companies, particularly Cisco Systems, Inc., Dell, Hewlett-Packard Enterprise Co., Huawei Technologies Co. Ltd., Arista NetworksInc., Arris Corporation, and Juniper Networks Inc. Most of these competitors have longer operating histories, greater name recognition, larger customer bases,broader product lines and substantially greater financial, technical, sales, marketing and other resources.We expect to face increased competition from both traditional networking solutions companies and Cloud platform companies offering Infrastructure-as-a-Service (“IaaS”) and Platform-as-a-Service (“PaaS”) products to enterprise customers. In that regard, we expect to face increased competition from certainCloud Computing companies such as Amazon Web Services (“AWS”), Microsoft (“Microsoft Azure”), and Google Inc. (“Google Cloud Platform”) providinga cloud-based platform of data center compute and networking services for enterprise customers.With the acquisitions of assets from Zebra, Avaya and Brocade, we believe Extreme is uniquely positioned to address the most pressing market needsfrom the campus to the data center. Although we believe that our solutions and strategy will improve our ability to meeting the needs of our current andpotential customers we cannot guarantee future success.RestructuringFiscal year 2016During fiscal 2016, we continued to realign our operations by abandoning excess facilities, primarily in San Jose, California; Salem, New Hampshireand Morrisville, North Carolina in addition to other smaller leased locations. These excess facilities represented approximately 32% of the floor space in theaggregate at these locations and included general office and warehouse space.Fiscal year 2017During fiscal 2017, we continued to realign our operations by continuing to review our excess facilities, expected sublease income, and implementeda reduction-in-force. We subleased our previous headquarters location at Rio Robles Drive in San Jose, California (“Rio Robles”) and moved into a largerlocation at 6480 Via del Oro in San Jose, California (“Via del Oro”) acquired as part of the WLAN Business acquisition. Additionally, due to the acquisitionsof the Campus Fabric Business and the Data Center Business, there was a need to accommodate the increase in headcount. To address this need, theCompany reoccupied a majority of the previously exited space in its Salem, New Hampshire location. In addition, we announced a reduction-in-force duringthe fiscal year affecting 90 employees. 17 Fiscal year 2018During fiscal 2018, we executed a plan to re-align our resources to take advantage of new growth opportunities as a result of the acquisitions of theCampus Fabric Business and the Data Center Business. The restructuring plan is expected to reduce our overall costs and to accelerate the achievement of ouroperating margin target objectives. The costs associated with this restructuring plan primarily included employee severance and benefits expenses andaffected 180 employees.Environmental MattersWe are subject to various environmental and other regulations governing product safety, materials usage, packaging and other environmental impactsin the United States and in various countries where our products are manufactured and sold. We are also subject to regulatory developments, including recentSEC disclosure regulations relating to so-called "conflict minerals," relating to ethically responsible sourcing of the components and materials used in ourproducts. To date, compliance with federal, state, local, and foreign laws enacted for the protection of the environment has had no material effect on ourcapital expenditures, earnings, or competitive position.We are committed to energy efficiency in our product lines. Accordingly, we believe this is an area that affords us a competitive advantage for ourproducts in the marketplace. We maintain compliance with various regulations related to the environment, including the Waste Electrical and ElectronicEquipment and the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment regulations adopted by the EuropeanUnion. To date, our compliance efforts with various United States and foreign regulations related to the environment has not had a material effect on ouroperating results.EmployeesAs of June 30, 2018, we employed 2,713 people, including 931 in sales and marketing, 999 in research and development, 249 in operations, 393 incustomer support and services and 141 in finance and administration. We have never had a work stoppage and no employees in the United States arerepresented under a collective bargaining agreement. We consider our employee relations to be good.We believe our future success depends on our continued ability to attract, integrate, retain, train and motivate highly qualified employees, and uponthe continued service of our senior management and key employees. None of our executive officers or key employees is bound by an employment agreementwhich mandates that the employee render services for any specific term. The market for qualified personnel is highly competitive.OrganizationWe were incorporated in California in May 1996, and reincorporated in Delaware in March 1999.

Item 1A. Risk FactorsThe following is a list of risks and uncertainties which may have a material and adverse effect on our business, operations, industry, financialcondition, results of operations or future financial performance. While we believe we have identified and discussed below the key risk factors affecting ourbusiness, there may be additional risks and uncertainties that are not presently known or that are not currently believed to be significant that may adverselyaffect our business, results of operations, industry, financial position and financial performance in the future.We may not realize anticipated benefits of past or future acquisitions, divestitures and strategic investments, and the integration of acquiredcompanies or technologies may negatively impact our business and financial results or dilute the ownership interests of our stockholders.18 As part of our business strategy, we review acquisition and strategic investment prospects that we believe would complement our current productofferings, augment our market coverage or enhance our technical capabilities, or otherwise offer growth opportunities. In the event of any future acquisitions,we could: •issue equity securities which would dilute current stockholders' percentage ownership; •incur additional debt; •assume contingent liabilities; or •expend significant cash.These actions could have a material adverse effect on our operating results or the price of our common stock.For example, on October 28, 2016, we completed the acquisition of the WLAN Business from Zebra and amended our prior credit facility with ourlenders to finance the acquisition. On July 14, 2017, we completed the acquisition of the Campus Fabric Business and on October 27, 2017, we completedour acquisition of the Data Center Business. Upon the terms and subject to the conditions of the respective Asset Purchase Agreements, we acquiredcustomers, employees, technology and other assets, as well as assumed certain contracts and other liabilities of the Campus Fabric and Data CenterBusinesses. As of June 30, 2018, we have $200 million of indebtedness outstanding under our current Credit Agreement.There can be no assurance we will achieve the revenues, growth prospects and synergies expected from any acquisition or that we will achieve suchrevenue, growth prospects and synergies in the anticipated time period and our failure to do so could have a material adverse effect on our business, operatingresults and financial condition. Moreover, even if we do obtain benefits in the form of increased sales and earnings, these benefits may be recognized muchlater than the time when the expenses associated with an acquisition are incurred. This is particularly relevant in cases where it would be necessary tointegrate new types of technology into our existing portfolio and new types of products may be targeted for potential customers with which we do not havepre-existing relationships.Our ability to realize the anticipated benefits of our acquisitions and investment activities, including the WLAN Business, Campus Fabric Businessand Data Center Business, also entail numerous risks, including, but not limited to: •difficulties in the assimilation and successful integration of acquired operations, sales functions, technologies and/or products; •unanticipated costs, litigation or other contingent liabilities associated with the acquisition or investment transaction; •incurrence of acquisition- and integration-related costs, goodwill or in-process research and development impairment charges, or amortizationcosts for acquired intangible assets, that could negatively impact our operating results and financial condition; •the diversion of management's attention from other business concerns; •adverse effects on existing business relationships with suppliers and customers; •risks associated with entering markets in which we have no or limited prior experience; •the potential loss of key employees of acquired organizations and inability to attract or retain other key employees; and •substantial charges for the amortization of certain purchased intangible assets, deferred stock compensation or similar items.In addition, we may not be able to successfully integrate any businesses, products, technologies, or personnel that we might acquire in the future, andour failure to do so could have a material adverse effect on our business, operating results and financial condition.Our credit facilities impose financial and operating restrictions on us.Our debt instruments, including our Credit Agreement, impose, and the terms of any future debt may impose, operating and other restrictions on us.These restrictions could affect, and in many respects limit or prohibit, among other items, our ability to: •incur additional indebtedness; •create liens; •make investments; •enter into transactions with affiliates; •sell assets;19 •guarantee indebtedness; •declare or pay dividends or other distributions to stockholders; •repurchase equity interests; •change the nature of our business; •enter into swap agreements; •issue or sell capital stock of certain of our subsidiaries; and •consolidate, merge, or transfer all or substantially all of our assets and the assets of our subsidiaries on a consolidated basis.The agreements governing our Credit Agreement also require us to achieve and maintain compliance with specified financial ratios. A breach of any ofthese restrictive covenants or the inability to comply with the required financial ratios could result in a default under our debt instruments. If any such defaultoccurs, the lenders under our Credit Agreement may elect to declare all outstanding borrowings, together with accrued interest and other fees, to beimmediately due and payable. The lenders under our credit agreement also have the right in these circumstances to terminate any commitments they have toprovide further borrowings.If we fail to meet our payment or other obligations under our Credit Agreement the lenders under such Credit Agreement, as amended, couldforeclose on, and acquire control of, substantially all of our assets.Our Credit Agreement is jointly and severally guaranteed by us and certain of our subsidiaries. Borrowings under our Credit Agreement are secured byliens on substantially all of our assets, including the capital stock of certain of our subsidiaries, and the assets of our subsidiaries that are loan partyguarantors. If we are unable to repay outstanding borrowings when due, the lenders under our Credit Agreement will have the right to proceed against thispledged capital stock and take control of substantially all of our assets.To successfully manage our business or achieve our goals, we must attract, retain, train, motivate, develop and promote key employees, andfailure to do so can harm us.Our success depends to a significant degree upon the continued contributions of our key management, engineering, sales and marketing, service andoperations personnel, many of whom would be difficult to replace. We do not have employment contracts with these individuals that mandate that theyrender services for any specific term, nor do we carry life insurance on any of our key personnel. We have experienced and may in the future experiencesignificant turnover in our executive personnel. Changes in our management and key employees could affect our financial results, and a recent reduction inforce, may impede our ability to attract and retain highly skilled personnel. We believe our future success will also depend in large part upon our ability toattract and retain highly skilled managerial, engineering, sales and marketing, service, finance and operations personnel. The market for these personnel iscompetitive, and we have had difficulty in hiring employees, particularly engineers, in the time-frame we desire.A number of our employees are foreign nationals who rely on visas and entry permits in order to legally work in the United States and othercountries. In recent years, the United States has increased the level of scrutiny in granting H-1(B), L-1 and other business visas. In addition, the current U.S.administration has indicated that immigration reform is a priority. Compliance with United States immigration and labor laws could require us to incuradditional unexpected labor costs and expenses or could restrain our ability to retain skilled professionals. Any of these restrictions could have a materialadverse effect on our business, results of operations and financial conditions.We cannot assure future profitability, and our financial results may fluctuate significantly from period to period.We have reported losses in each of our five most recent fiscal years. In addition, in years when we reported profits, we were not profitable in eachquarter during those years. We anticipate continuing to incur significant sales and marketing, product development and general and administrative expenses.Any delay in generating or recognizing revenue could result in a loss for a quarter or full year. Even if we are profitable, our operating results may fall belowour expectations and those of our investors, which could cause the price of our stock to fall.We may experience challenges or delays in generating or recognizing revenue for a number of reasons and our revenue and operating results havevaried significantly in the past and may vary significantly in the future due to a number of factors, including, but not limited to, the following: •our dependence on obtaining orders during a quarter and shipping those orders in the same quarter to achieve our revenue objectives; •decreases in the prices of the products we sell; •the mix of products sold and the mix of distribution channels through which products are sold;20 •acceptance provisions in customer contracts; •our ability to deliver installation or inspection services by the end of the quarter; •changes in general and/or specific economic conditions in the networking industry; •seasonal fluctuations in demand for our products and services; •a disproportionate percentage of our sales occurring in the last month of the quarter; •our ability to ship products by the end of a quarter; •reduced visibility into the implementation cycles for our products and our customers’ spending plans; •our ability to forecast demand for our products, which in the case of lower-than-expected sales, may result in excess or obsolete inventory inaddition to non-cancelable purchase commitments for component parts; •our sales to the telecommunications service provider market, which represents a significant source of large product orders, being especially volatileand difficult to forecast; •product returns or the cancellation or rescheduling of orders; •announcements and new product introductions by our competitors; •our ability to develop and support relationships with enterprise customers, service providers and other potential large customers; •our ability to achieve and maintain targeted cost reductions; •fluctuations in warranty or other service expenses actually incurred; •our ability to obtain sufficient supplies of sole- or limited-source components for our products on a timely basis; •increases in the price of the components we purchase; and •changes in funding for customer technology purchases in our markets.Due to the foregoing and other factors, many of which are described herein, period-to-period comparisons of our operating results should not be reliedupon as an indicator of our future performance.The global economic environment has and may continue to negatively impact our business and operating results.The challenges and uncertainty currently affecting global economic conditions may negatively impact our business and operating results in thefollowing ways: •customers may delay or cancel plans to purchase our products and services; •customers may not be able to pay, or may delay payment of, the amounts they owe us, which may adversely affect our cash flow, the timing of ourrevenue recognition and the amount of our revenue; •increased pricing pressure may result from our competitors aggressively discounting their products; •accurate budgeting and planning will be difficult due to low visibility into future sales; •forecasting customer demand will be more difficult, increasing the risk of either excess and obsolete inventory if our forecast is too high orinsufficient inventory to meet customer demand if our forecast is too low; and •our component suppliers and contract manufacturers have been negatively affected by the economy, which may result in product delays andchanges in pricing and service levels.If global economic conditions do not show continued improvement, we believe we could experience material adverse impacts to our business andoperating results.21 We depend upon international sales for a significant portion of our revenue which imposes a number of risks on our business.International sales constitute a significant portion of our net revenue. Our ability to grow will depend in part on the expansion of international sales.Our international sales primarily depend on the success of our resellers and distributors. The failure of these resellers and distributors to sell our productsinternationally would limit our ability to sustain and grow our revenue. There are a number of risks arising from our international business, including: •longer accounts receivable collection cycles; •difficulties in managing operations across disparate geographic areas; •difficulties associated with enforcing agreements through foreign legal systems; •reduced or limited protection of intellectual property rights, particularly in jurisdictions that have less developed intellectual property regimes,such as China and India; •higher credit risks requiring cash in advance or letters of credit; •potential adverse tax consequences; •compliance with regulatory requirements of foreign countries, including compliance with rapidly evolving environmental regulations; •compliance with U.S. laws and regulations pertaining to the sale and distribution of products to customers in foreign countries, including exportcontrols and the Foreign Corrupt Practices Act; •the payment of operating expenses in local currencies, which exposes us to risks of currency fluctuations: •political and economic turbulence or uncertainty, such as the United Kingdom’s 2016 referendum, commonly referred to as “Brexit” that hascreated economic and political uncertainty in the European Union; •terrorism, war or other armed conflict; •compliance with U.S. and other applicable government regulations prohibiting certain end-uses and restrictions on trade with embargoed orsanctioned countries, such as Russia, and with denied parties; •potential import tariffs imposed by the United States and the possibility of reciprocal tariffs by foreign countries; •difficulty in conducting due diligence with respect to business partners in certain international markets; •increased complexity of accounting rules and financial reporting requirements; •fluctuations in local economies; and •natural disasters and epidemics.Any or all of these factors could have a material adverse impact on our business, financial condition, and results of operations.Substantially all of our international sales are United States dollar-denominated. The continued strength and future increases in the value of theUnited States dollar relative to foreign currencies could make our products less competitive in international markets. In the future, we may elect to invoicesome of our international customers in local currency, which would expose us to fluctuations in exchange rates between the United States dollar and theparticular local currency. If we do so, we may decide to engage in hedging transactions to minimize the risk of such fluctuations.We have entered into foreign exchange forward contracts to offset the impact of payment of operating expenses in local currencies to some of ouroperating foreign subsidiaries. However, if we are not successful in managing these foreign currency transactions, we could incur losses from these activities.Local laws and customs in many countries differ significantly from, or conflict with, those in the United States or in other countries in which weoperate. In many foreign countries, it is common for others to engage in business practices that are prohibited by our internal policies and procedures or U.S.regulations applicable to us. Although we have implemented policies, procedures and training designed to ensure compliance with these U.S. and foreignlaws and policies, there can be no complete assurance that any individual employee, contractor, channel partner, or agents will not violate our policies andprocedures. Violations of laws or key control policies by our employees, contractors, channel partners, or agents could result in termination of ourrelationship, financial reporting problems, fines, and/or penalties for us, or prohibition on the importation or exportation of our products, and could have amaterial adverse effect on our business, financial condition and results of operations.22 We expect the average selling price of our products to decrease, which is likely to reduce gross margin and/or revenue.The network equipment industry has traditionally experienced an erosion of average selling prices due to a number of factors, including competitivepricing pressures, promotional pricing and technological progress. We anticipate the average selling prices of our products will decrease in the future inresponse to competitive pricing pressures, excess inventories, increased sales discounts and new product introductions by us or our competitors. We mayexperience decreases in future operating results due to the erosion of our average selling prices. To maintain our gross margin, we must develop and introduceon a timely basis new products and product enhancements and continually reduce our product costs. Our failure to do so would likely cause our revenue andgross margin to decline.We purchase several key components for products from single or limited sources and could lose sales if these suppliers fail to meet our needs.We currently purchase several key components used in the manufacturing of our products from single or limited sources and are dependent uponsupply from these sources to meet our needs. Certain components such as tantalum capacitors, SRAM, DRAM, and printed circuit boards, have been in thepast, and may in the future be, in short supply. We have encountered, and are likely in the future to encounter, shortages and delays in obtaining these orother components, and this could have a material adverse effect on our ability to meet customer orders. Our principal sole-source components include: •ASICs - merchant silicon, Ethernet switching, custom and physical interface; •microprocessors; •programmable integrated circuits; •selected other integrated circuits; •custom power supplies; and •custom-tooled sheet metal.Our principal limited-source components include: •flash memory; •DRAMs and SRAMs; •printed circuit boards; •CAMs; •connectors; and •timing circuits (crystals & clocks).We use our forecast of expected demand to determine our material requirements. Lead times for materials and components we order vary significantly,and depend on factors such as the specific supplier, contract terms and demand for a component at a given time. If forecasts exceed orders, we may haveexcess and/or obsolete inventory, which could have a material adverse effect on our operating results and financial condition. If orders exceed forecasts, wemay have inadequate supplies of certain materials and components, which could have a material adverse effect on our ability to meet customer deliveryrequirements and to recognize revenue.Our top ten suppliers accounted for a significant portion of our purchases during the quarter. Given the significant concentration of our supply chain,particularly with certain sole or limited source providers, any significant interruption by any of the key suppliers or a termination of a relationship couldtemporarily disrupt our operations. Additionally, our operations are materially dependent upon the continued market acceptance and quality of thesemanufacturers’ products and their ability to continue to manufacture products that are competitive and that comply with laws relating to environmental andefficiency standards. Our inability to obtain products from one or more of these suppliers or a decline in market acceptance of these suppliers’ products couldhave a material adverse effect on our business, results of operations and financial condition. Other than pursuant to an agreement with a key componentsupplier which includes pricing based on a minimum volume commitment, generally we do not have agreements fixing long-term prices or minimum volumerequirements from suppliers. From time to time we have experienced shortages and allocations of certain components, resulting in delays in filling orders.Qualifying new suppliers to compensate for such shortages may be time-consuming and costly and may increase the likelihood of errors in design orproduction. In addition, during the development of our products, we have experienced delays in the prototyping of our chipsets, which in turn has led todelays in product introductions. Similar delays may occur in the future. Furthermore, the performance of the components from our suppliers as incorporated inour products may not meet the quality requirements of our customers.23 Intense competition in the market for networking equipment and Cloud platform companies could prevent us from increasing revenue andattaining profitability.The market for network switching solutions is intensely competitive and dominated primarily by Cisco Systems Inc., Dell, Inc. Hewlett-PackardEnterprise Company, Huawei Technologies Co. Ltd., Arista Networks, Inc., Arris Corporation and Juniper Networks, Inc. Most of our competitors have longeroperating histories, greater name recognition, larger customer bases, broader product lines and substantially greater financial, technical, sales, marketing andother resources. As a result, these competitors are able to devote greater resources to the development, promotion, sale and support of their products. Inaddition, they have larger distribution channels, stronger brand names, access to more customers, a larger installed customer base and a greater ability tomake attractive offers to channel partners and customers than we do. Some of our customers may question whether we have the financial resources tocomplete their projects and future service commitments.We may also face increased competition from both traditional networking solutions companies and Cloud platform companies offering IaaS and PaaSproducts to enterprise customers. In particular, AWS, Microsoft Azure and the Google Cloud Platform may provide enterprise customers with a cloud-basedplatform of data center compute and networking services.For example, we have encountered, and expect to continue to encounter in the future, many potential customers who are confident in and committedto the product offerings of our principal competitors. Accordingly, these potential customers may not consider or evaluate our products. When such potentialcustomers have considered or evaluated our products, we have in the past lost, and expect in the future to lose, sales to some of these customers as largecompetitors have offered significant price discounts to secure these sales.The pricing policies of our competitors impact the overall demand for our products and services. Some of our competitors are capable of operating atsignificant losses for extended periods of time, increasing pricing pressure on our products and services. If we do not maintain competitive pricing, thedemand for our products and services, as well as our market share, may decline. From time to time, we may lower the prices of our products and services inresponse to competitive pressure. When this happens, if we are unable to reduce our component costs or improve operating efficiencies, our revenue and grossmargins will be adversely affected.We may not fully realize the anticipated positive impacts to future financial results from our restructuring efforts.We have undertaken restructuring efforts in the past to streamline operations and reduce operating expenses. Our ability to achieve the anticipatedcost savings and other benefits from our restructuring efforts within expected time frames is subject to many estimates and assumptions and may varymaterially based on factors such as market conditions and the effect of our restructuring efforts on our work force. These estimates and assumptions aresubject to significant economic, competitive and other uncertainties, some of which are beyond our control. We cannot assure that we will fully realize theanticipated positive impacts to future financial results from our current or future restructuring efforts. If our estimates and assumptions are incorrect or if otherunforeseen events occur, we may not achieve the cost savings expected from such restructurings, and our business and results of operations could beadversely affected.Industry consolidation may lead to stronger competition and may harm our operating results.There has been a trend toward industry consolidation in our markets for several years. We expect this trend to continue as companies attempt tostrengthen or hold their market positions in an evolving industry and as companies are acquired or are unable to continue operations. For example, some ofour current and potential competitors for enterprise data center business have made acquisitions or announced new strategic alliances, designed to positionthem with the ability to provide end-to-end technology solutions for the enterprise data center. Companies that are strategic alliance partners in some areas ofour business may acquire or form alliances with our competitors, thereby reducing their business with us. We believe industry consolidation may result instronger competitors that are better able to compete as sole-source vendors for customers. This could lead to more variability in our operating results andcould have a material adverse effect on our business, operating results, and financial condition. Furthermore, particularly in the service provider market, rapidconsolidation will lead to fewer customers, with the effect that loss of a major customer could have a material impact on results not anticipated in a customermarketplace composed of more numerous participants.We intend to invest in engineering, sales, services, marketing and manufacturing on a long-term basis, and delays or inability to attain theexpected benefits may result in unfavorable operating results.While we intend to focus on managing our costs and expenses, over the long term, we also intend to invest in personnel and other resources related toour engineering, sales, services, marketing and manufacturing functions as we focus on our foundational priorities, such as leadership in our core productsand solutions and architectures for business transformation. We are likely to recognize the costs associated with these investments earlier than some of theanticipated benefits and the return on these investments may be lower, or may develop more slowly, than we expect. If we do not achieve the benefitsanticipated from these investments, or if the achievement of these benefits is delayed, our operating results may be adversely affected.24 Our success is dependent on our ability to continually introduce new products and features that achieve broad market acceptance.The network equipment market is characterized by rapid technological progress, frequent new product introductions, changes in customerrequirements and evolving industry standards. If we do not regularly introduce new products in this dynamic environment, our product lines will becomeobsolete. These new products must be compatible and inter-operate with products and architectures offered by other vendors. We have and may in the futureexperience delays in product development and releases, and such delays have and could in the future adversely affect our ability to compete and ouroperating results.When we announce new products or product enhancements that have the potential to replace or shorten the life cycle of our existing products,customers may defer or cancel orders for our existing products; in addition, ending sales of existing products may cause customers to cancel or defer ordersfor our existing products. These actions could have a material adverse effect on our operating results by unexpectedly decreasing sales, increasing inventorylevels of older products and exposing us to greater risk of product obsolescence.Even if we introduce new switching products, alternative technologies could achieve widespread market acceptance and displace the Ethernettechnology on which we have based our product architecture. For example, developments in routers and routing software could significantly reduce demandfor our products. As a result, we may not be able to achieve widespread market acceptance of our current or future products.If we do not successfully anticipate technological shifts, market needs and opportunities, and develop products, product enhancements andbusiness strategies that meet those technological shifts, needs and opportunities, or if those products are not made available or strategies are notexecuted in a timely manner or do not gain market acceptance, we may not be able to compete effectively and our ability to generate revenues willsuffer.The markets for our products are constantly evolving and characterized by rapid technological change, frequent product introductions, changes incustomer requirements, and continuous pricing pressures. We cannot guarantee that we will be able to anticipate future technological shifts, market needs andopportunities or be able to develop new products, product enhancements and business strategies to meet such technological shifts, needs or opportunities in atimely manner or at all. For example, the move from traditional network infrastructures towards SDN has been receiving considerable attention. In our view, itwill take several years to see the full impact of SDN, and we believe the successful products and solutions in this market will combine hardware and softwareelements together. If we fail to anticipate market requirements or opportunities or fail to develop and introduce new products, product enhancements orbusiness strategies to meet those requirements or opportunities in a timely manner, it could cause us to lose customers, and such failure could substantiallydecrease or delay market acceptance and sales of our present and future products and services, which would significantly harm our business, financialcondition, and results of operations. Even if we are able to anticipate, develop and commercially introduce new products and enhancements, we cannot assurethat new products or enhancements will achieve widespread market acceptance.Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards andrequirements, which could have a material adverse effect on our business.We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees could include intentional failures to: •comply with securities laws and regulations or similar regulations of comparable foreign regulatory authorities; •comply with export controls and sanctions laws and regulations or similar regulations of comparable foreign regulatory authorities; •comply with anti-corruption laws and regulations or similar regulations of comparable foreign regulatory authorities; •comply with internal controls that we have established; •report financial information or data accurately; or •disclose unauthorized activities to us.The precautions we take to detect and prevent misconduct may not be effective in controlling unknown or unmanaged risks or losses or inprotecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If anysuch actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impacton our business and results of operations, including the imposition of significant fines or other sanctions.25 The cloud networking market is still in its early stages and is rapidly evolving. If this market does not evolve as we anticipate or our target endcustomers do not adopt our cloud networking solutions, we may not be able to compete effectively, and our ability to generate revenue will suffer.The cloud networking market is still in its early stages. The market demand for cloud networking solutions has increased in recent years as endcustomers have deployed larger networks and have increased the use of virtualization and cloud computing. Our success may be impacted by our ability toprovide successful cloud networking solutions that address the needs of our channel partners and end customers more effectively and economically thanthose of other competitors or existing technologies. If the cloud networking solutions market does not develop in the way we anticipate, if our solutions donot offer significant benefits compared to competing legacy network switching products or if end customers do not recognize the benefits that our solutionsprovide, then our potential for growth in this cloud market could be adversely affected.Claims of infringement by others may increase and the resolution of such claims may adversely affect our operating results.Our industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patents, copyrights(including rights to “open source” software) and other intellectual property rights. As we have grown it has, and may continue to, experience greater revenuesand increased public visibility, which may cause competitors, customers, and governmental authorities to be more likely to initiate litigation against us.Because of the existence of a large number of patents in the networking field, the secrecy of some pending patents and the issuance of new patents at a rapidpace, it is not possible to determine in advance if a product or component might infringe the patent rights of others. Because of the potential for courtsawarding substantial damages, the lack of predictability of such awards and the high legal costs associated with the defense of such patent infringementmatters that would be expended to prove lack of infringement, it is not uncommon for companies in our industry to settle even potentially unmeritoriousclaims for very substantial amounts. Furthermore, the entities with whom we have or could have disputes or discussions include entities with extensive patentportfolios and substantial financial assets. These entities are actively engaged in programs to generate substantial revenue from their patent portfolios and areseeking or may seek significant payments or royalties from us and others in our industry.Litigation resulting from claims that we are infringing the proprietary rights of others has resulted and could in the future result in substantial costsand a diversion of resources, and could have a material adverse effect on our business, financial condition and results of operations. We previously receivednotices from entities alleging that we were infringing their patents and have been party to patent litigation in the past.Without regard to the merits of these or any other claims, an adverse court order or a settlement could require us, among other actions, to: •stop selling our products that incorporate the challenged intellectual property; •obtain a royalty bearing license to sell or use the relevant technology, and that license may not be available on reasonable terms or available at all; •pay damages; •redesign those products that use the disputed technology; or •face a ban on importation of our products into the United States.In addition, our products include so-called “open source” software. Open source software is typically licensed for use at no initial charge, but imposeson the user of the open source software certain requirements to license to others both the open source software as well as modifications to the open sourcesoftware under certain circumstances. Our use of open source software subjects us to certain additional risks for the following reasons: •open source license terms may be ambiguous and may result in unanticipated obligations regarding the licensing of our products and intellectualproperty; •open source software cannot be protected under trade secret law; •suppliers of open-source software do not provide the warranty, support and liability protections typically provided by vendors who offerproprietary software; and •it may be difficult for us to accurately determine the developers of the open source code and whether the acquired software infringes third-partyintellectual property rights.We believe even if we do not infringe the rights of others, we will incur significant expenses in the future due to defense of legal claims, disputes orlicensing negotiations, though the amounts cannot be determined. These expenses may be material or otherwise adversely affect our operating results.26 Our operating results may be negatively affected by legal proceedings.We have in the past, currently are and will likely in the future pursue or be subject to claims or lawsuits in the normal course of our business. Inaddition to the risks related to the intellectual property lawsuits described above, we are currently parties to other litigation as described in Note 9 to ourNotes to Consolidated Financial Statements included elsewhere in this Annual Report. Regardless of the result, litigation can be expensive, lengthy anddisruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to predict. An unfavorable resolution of a lawsuit inwhich we are a defendant could result in a court order against us or payments to other parties that would have an adverse effect on our business, results ofoperations or financial condition. Even if we are successful in prosecuting claims and lawsuits, we may not recover damages sufficient to cover our expensesincurred to manage, investigate and pursue the litigation. In addition, subject to certain limitations, we may be obligated to indemnify our current and formercustomers, suppliers, directors, officers and employees in certain lawsuits. We may not have adequate insurance coverage to cover all of our litigation costsand liabilities.Failure to protect our intellectual property could affect our business.We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights.However, we cannot ensure that the actions we have taken will adequately protect our intellectual property rights or that other parties will not independentlydevelop similar or competing products that do not infringe on our patents. We generally enter into confidentiality, invention assignment or licenseagreements with our employees, consultants and other third parties with whom we do business, and control access to and distribution of our intellectualproperty and other proprietary information. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy or otherwisemisappropriate or use our products or technology, which would adversely affect our business.When our products contain undetected errors, we may incur significant unexpected expenses and could lose sales.Network products frequently contain undetected errors when new products or new versions or updates of existing products are released to themarketplace. In the past, we have experienced such errors in connection with new products and product updates. We have experienced component problemsin prior years that caused us to incur higher than expected warranty, service costs and expenses, and other related operating expenses. In the future, we expectthat, from time to time, such errors or component failures will be found in new or existing products after the commencement of commercial shipments. Theseproblems may have a material adverse effect on our business by causing us to incur significant warranty, repair and replacement costs, diverting the attentionof our engineering personnel from new product development efforts, delaying the recognition of revenue and causing significant customer relationsproblems. Further, if products are not accepted by customers due to such defects, and such returns exceed the amount we accrued for defective returns basedon our historical experience, our operating results would be adversely affected.Our products must successfully inter-operate with products from other vendors. As a result, when problems occur in a network, it may be difficult toidentify the sources of these problems. The occurrence of system errors, whether or not caused by our products, could result in the delay or loss of marketacceptance of our products and any necessary revisions may cause us to incur significant expenses. The occurrence of any such problems would likely have amaterial adverse effect on our business, operating results and financial condition.Our dependence on a few manufacturers for our manufacturing requirements could harm our operating results.We primarily rely on our manufacturing partners: Alpha Networks; Senao Networks; Foxconn; Delta Networks and Wistron NeWeb Corporation andselect other partners to manufacture our products. We have experienced delays in product shipments from some of our manufacturing partners in the past,which in turn delayed product shipments to our customers. These or similar problems may arise in the future, such as delivery of products of inferior quality,delivery of insufficient quantity of products, or the interruption or discontinuance of operations of a manufacturer, any of which could have a materialadverse effect on our business and operating results. In addition, any natural disaster or business interruption to our manufacturing partners couldsignificantly disrupt our business. While we maintain strong relationships with our manufacturing partners, our agreements with these manufacturers aregenerally of limited duration and pricing, quality and volume commitments are negotiated on a recurring basis. The failure to maintain continuingagreements with our manufacturing partners could adversely affect our business. We intend to introduce new products and product enhancements, which willrequire that we rapidly achieve volume production by coordinating our efforts with those of our suppliers and contract manufacturers.As part of our cost-reduction efforts, we will need to realize lower per unit product costs from our manufacturing partners by means of volumeefficiencies and the utilization of manufacturing sites in lower-cost geographies. However, we cannot be certain when or if such price reductions will occur.The failure to obtain such price reductions would adversely affect our operating results.27 We must continue to develop and increase the productivity of our indirect distribution channels to increase net revenue and improve ouroperating results.Our distribution strategy focuses primarily on developing and increasing the productivity of our indirect distribution channels. If we fail to developand cultivate relationships with significant channel partners, or if these channel partners are not successful in their sales efforts, sales of our products maydecrease and our operating results could suffer. Many of our channel partners also sell products from other vendors that compete with our products. Ourchannel partners may not continue to market or sell our products effectively or to devote the resources necessary to provide us with effective sales, marketingand technical support. We may not be able to successfully manage our sales channels or enter into additional reseller and/or distribution agreements. Ourfailure to do any of these could limit our ability to grow or sustain revenue.Our operating results for any given period have and will continue to depend to a significant extent on large orders from a relatively small number ofchannel partners and other customers. However, we do not have binding purchase commitments from any of them. A substantial reduction or delay in sales ofour products to a significant reseller, distributor or other customer could harm our business, operating results and financial condition because our expenselevels are based on our expectations as to future revenue and to a large extent are fixed in the short term. Under specified conditions, some third-partydistributors are allowed to return products to us and unexpected returns could adversely affect our results.The sales cycle for our products is long and we may incur substantial non-recoverable expenses or devote significant resources to sales that donot occur when anticipated.The purchase of our products represent a significant strategic decision by a customer regarding its communications infrastructure. The decision bycustomers to purchase our products is often based on the results of a variety of internal procedures associated with the evaluation, testing, implementationand acceptance of new technologies. Accordingly, the product evaluation process frequently results in a lengthy sales cycle, typically ranging from threemonths to longer than a year, and as a result, our ability to sell products is subject to a number of significant risks, including risks that: •budgetary constraints and internal acceptance reviews by customers will result in the loss of potential sales; •there may be substantial variation in the length of the sales cycle from customer to customer, making decisions on the expenditure of resourcesdifficult to assess; •we may incur substantial sales and marketing expenses and expend significant management time in an attempt to initiate or increase the sale ofproducts to customers, but not succeed; •if a sales forecast from a specific customer for a particular quarter is not achieved in that quarter, we may be unable to compensate for the shortfall,which could harm our operating results; and •downward pricing pressures could occur during the lengthy sales cycle for our products.Failure to successfully expand our sales and support teams or educate them in regard to technologies and our product families may harm ouroperating results.The sale of our products and services requires a concerted effort that is frequently targeted at several levels within a prospective customer'sorganization. We may not be able to increase net revenue unless we expand our sales and support teams in order to address all of the customer requirementsnecessary to sell our products.We cannot assure that we will be able to successfully integrate employees into our Company or to educate and train current and future employees inregard to rapidly evolving technologies and our product families. A failure to do so may hurt our revenue growth and operating results.Failure of our products to comply with evolving industry standards and complex government regulations may adversely impact our business.If we do not comply with existing or evolving industry standards and government regulations, we may not be able to sell our products where thesestandards or regulations apply. The network equipment industry in which we compete is characterized by rapid changes in technology and customers'requirements and evolving industry standards. As a result, our success depends on: •the timely adoption and market acceptance of industry standards, and timely resolution of conflicting U.S. and international industry standards;and •our ability to influence the development of emerging industry standards and to introduce new and enhanced products that are compatible withsuch standards.In the past, we have introduced new products that were not compatible with certain technological standards, and in the future, we may not be able toeffectively address the compatibility and interoperability issues that arise as a result of technological changes and evolving industry standards.28 Our products must also comply with various U.S. federal government regulations and standards defined by agencies such as the FederalCommunications Commission, standards established by governmental authorities in various foreign countries and recommendations of the InternationalTelecommunication Union. In some circumstances, we must obtain regulatory approvals or certificates of compliance before we can offer or distribute ourproducts in certain jurisdictions or to certain customers. Complying with new regulations or obtaining certifications can be costly and disruptive to ourbusiness.If we do not comply with existing or evolving industry standards or government regulations, we will not be able to sell our products where thesestandards or regulations apply, which may prevent us from sustaining our net revenue or achieving profitability.If we do not adequately manage and evolve our financial reporting and managerial systems and processes, our ability to manage and grow ourbusiness may be harmed.Our ability to successfully implement our business plan and comply with regulations requires an effective planning and management process. Weneed to continue improving our existing, and implement new, operational and financial systems, procedures and controls. We need to ensure that anybusinesses acquired, including the WLAN Business, the Campus Fabric Business, and the Data Center Business are appropriately integrated in our financialsystems. Any delay in the implementation of, or disruption in the integration of acquired businesses, or delay and disruption in the transition to, new orenhanced systems, procedures or controls, could harm our ability to record and report financial and management information on a timely and accurate basis,or to forecast future results.Recent U.S. tax legislation may materially adversely affect our financial condition, results of operations and cash flows.Recently enacted U.S. tax legislation has significantly changed the U.S. federal income taxation of U.S. corporations, including by reducing the U.S.corporate income tax rate, limiting interest deductions, permitting immediate expensing of certain capital expenditures, adopting elements of a territorial taxsystem, imposing a one-time transition tax (or “repatriation tax”) on all undistributed earnings and profits of certain U.S.-owned foreign corporations,revising the rules governing net operating losses and the rules governing foreign tax credits, and introducing new anti-base erosion provisions. Many of thesechanges are effective immediately, without any transition periods or grandfathering for existing transactions. The legislation is unclear in many respects andcould be subject to potential amendments and technical corrections, as well as interpretations and implementing regulations by the Treasury and InternalRevenue Service (“IRS”), any of which could lessen or increase certain adverse impacts of the legislation. In addition, it is unclear how these U.S. federalincome tax changes will affect state and local taxation, which often uses federal taxable income as a starting point for computing state and local taxliabilities.While our analysis and interpretation of this legislation is preliminary and ongoing, based on our current evaluation, we do not expect the reductionof the U.S. corporate income tax rate will have a materially adverse impact to our earnings given our U.S. valuation allowance. We also do not currentlybelieve the one-time transition tax will have a materially adverse impact given our ability to utilize existing tax attributes. An estimate of the impact wasrecorded in the second quarter of the fiscal year ending June 30, 2018, the period in which the tax legislation was enacted, however, these amounts may besubject to further adjustment in subsequent periods throughout fiscal 2018 in accordance with recent interpretive guidance issued by the SEC as well asfuture regulatory guidance. We believe the limitation on interest deductions, the expanded limitation on executive compensation deductions and the anti-base erosion provisions in the legislation may negatively impact our cash flows going forward. There may be other material adverse effects resulting from thelegislation that we have not yet identified.Changes in the effective tax rate including from the release of the valuation allowance recorded against our net U.S. deferred tax assets, or adverseoutcomes resulting from examination of our income or other tax returns or change in ownership, could adversely affect our results.Our future effective tax rates may be volatile or adversely affected by changes in our business or U.S. or foreign tax laws, including: the partial or fullrelease of the valuation allowance recorded against our net U.S. deferred tax assets; expiration of or lapses in the research and development tax credit laws;transfer pricing adjustments; tax effects of stock-based compensation; or costs related to restructuring. In addition, we are subject to the examination of ourincome tax returns by the Internal Revenue Service and other tax authorities. Although we regularly assess the likelihood of adverse outcomes resulting fromthese examinations to determine the adequacy of our provision for income taxes, there is no assurance that such determinations by us are in fact adequate.Changes in our effective tax rates or amounts assessed upon examination of our tax returns may have a material, adverse impact on our cash flows and ourfinancial condition.29 Our future effective tax rate in particular could be adversely affected by a change in ownership pursuant to U.S. Internal Revenue Code Section 382. Ifa change in ownership occurs, it may limit our ability to utilize our net operating losses to offset our U.S. taxable income. If U.S. taxable income is greaterthan the change in ownership limitation, we will pay a higher rate of tax with respect to the amount of taxable income that exceeds the limitation. This couldhave a material adverse impact on our results of operations. On April 26, 2012, we adopted an Amended and Restated Rights Agreement to help protect ourassets (the “Rights Agreement”). In general, this does not allow a stockholder to acquire more than 4.95% of our outstanding common stock without a waiverfrom our board of directors, who must take into account the relevant tax analysis relating to potential limitation of our net operating losses. Our RightsAgreement is effective through May 31, 2019, subject to ratification by a majority of our stockholders at the next annual shareholders meeting, expected tobe held on November 8, 2018.Provisions in our charter documents and Delaware law and our adoption of a stockholder rights plan may delay or prevent an acquisition ofExtreme, which could decrease the value of our Common Stock.Our certificate of incorporation and bylaws and Delaware law contain provisions that could make it more difficult for a third party to acquire uswithout the consent of our Board of Directors. Delaware law also imposes some restrictions on mergers and other business combinations between us and anyholder of 15% or more of our outstanding common stock. In addition, our Board of Directors has the right to issue preferred stock without stockholderapproval, which could be used to dilute the stock ownership of a potential hostile acquirer. Although we believe these provisions of our certificate ofincorporation and bylaws and Delaware law will provide for an opportunity to receive a higher bid by requiring potential acquirers to negotiate with ourBoard of Directors, these provisions apply even if the offer may be considered beneficial by some of our stockholders.Our Rights Agreement provides that if a single stockholder (or group) acquires more than 4.95% of our outstanding common stock without a waiverfrom our Board of Directors, each holder of one share of our common stock (other than the stockholder or group who acquired in excess of 4.95% of ourcommon stock) may purchase a fractional share of our preferred stock that would result in substantial dilution to the triggering stockholder or group.Accordingly, although this plan is designed to prevent any limitation on the utilization of our net operating losses by avoiding issues raised under Section382 of the U.S. Internal Revenue Code, the Rights Agreement could also serve as a deterrent to stockholders wishing to effect a change of control.Compliance with laws, rules and regulations relating to corporate governance and public disclosure may result in additional expenses.Federal securities laws, rules and regulations, as well as NASDAQ Stock Market rules and regulations, require companies to maintain extensivecorporate governance measures, impose comprehensive reporting and disclosure requirements, set strict independence and financial expertise standards foraudit and other committee members and impose civil and criminal penalties for companies and their Chief Executive Officers, Chief Financial Officers anddirectors for securities law violations. These laws, rules and regulations and the interpretation of these requirements are evolving, and we are makinginvestments to evaluate current practices and to continue to achieve compliance, which investments may have a material impact on our financial condition.We are required to evaluate the effectiveness of our internal control over financial reporting on an annual basis and publicly disclose anymaterial weaknesses in our controls. Any adverse results from such evaluation could result in a loss of investor confidence in our financial reports andsignificant expense to remediate, and ultimately could have an adverse effect on our stock price.Section 404 of the Sarbanes-Oxley Act of 2002 requires our management to assess the effectiveness of our internal control over financial reporting andto disclose if such controls were unable to provide assurance that a material error would be prevented or detected in a timely manner. We have an ongoingprogram to review the design of our internal controls framework in keeping with changes in business needs, implement necessary changes to our controlsdesign and test the system and process controls necessary to comply with these requirements. Because of the inherent limitations in all control systems, noevaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, ifany, within our Company will have been detected.If we or our independent registered public accounting firm identifies material weaknesses in our internal controls, the disclosure of that fact, even ifquickly remedied, may cause investors to lose confidence in our financial statements and its stock price may decline. Remediation of a material weaknesscould require us to incur significant expenses and, if we fail to remedy any material weakness, our ability to report our financial results on a timely andaccurate basis may be adversely affected, our access to the capital markets may be restricted, our stock price may decline, and we may be subject to sanctionsor investigation by regulatory authorities, including the U.S. Securities and Exchange Commission or the NASDAQ Stock Market LLC. We may also berequired to restate our financial statements from prior periods. Execution of restatements create a significant strain on our internal resources and could causedelays in our filing of quarterly or annual financial results, increase our costs and cause management distraction. Restatements may also significantly affectour stock price in an adverse manner.30 Our stock price has been volatile in the past and may significantly fluctuate in the future.In the past, our common stock price has fluctuated significantly. This could continue as we or our competitors announce new products, our results orthose of our customers or competition fluctuate, conditions in the networking or semiconductor industry change, or when investors, change their sentimenttoward stocks in the networking technology sector.In addition, fluctuations in our stock price and our price-to-earnings multiple may make our stock attractive to momentum, hedge or day-tradinginvestors who often shift funds into and out of stock rapidly, exacerbating price fluctuations in either direction, particularly when viewed on a quarterlybasis. These fluctuations may adversely affect the trading price or liquidity of our common stock. Some companies, including us, that have had volatilemarket prices for their securities have had securities class action lawsuits filed against them. If a suit were filed against us, regardless of its merits or outcome,it could result in substantial costs and divert management’s attention and resources. We rely on the availability of third-party licenses.Some of our products are designed to include software or other intellectual property, including open source software, licensed from third parties. Itmay be necessary in the future to seek or renew licenses relating to various aspects of these products. There can be no assurance that the necessary licenseswould be available on acceptable terms, if at all. The inability to obtain certain licenses or other rights or to obtain such licenses or rights on favorable terms,could have a material adverse effect on our business, operating results, and financial condition. Moreover, the inclusion in our products of software or otherintellectual property licensed from third parties on a nonexclusive basis could limit our ability to protect our proprietary rights in our products. Further, thefailure to comply with the terms of any license, including free open source software, may result in our inability to continue to use such license. Our inabilityto maintain or re-license any third-party licenses required in our products or our inability to obtain third-party licenses necessary to develop new productsand product enhancements, could require us, if possible, to develop substitute technology or obtain substitute technology of lower quality or performancestandards or at a greater cost, any of which could delay or prevent product shipment and harm our business, financial condition, and results of operations.System security risks, data protection breaches, and cyber-attacks could compromise our proprietary information, disrupt our internaloperations and harm public perception of our products, which could adversely affect our business.In the ordinary course of business, we store sensitive data, including intellectual property, our proprietary business information and that of ourcustomers, suppliers and business partners on our networks. In addition, we store sensitive or classified information through cloud-based services that may behosted by third parties and in data center infrastructure maintained by third parties. The secure maintenance of this information is critical to our operationsand business strategy. Increasingly, companies, including us, are subject to a wide variety of attacks on their networks on an ongoing basis. Despite oursecurity measures, our information technology and infrastructure may be vulnerable to penetration or attacks by computer programmers and hackers, orbreached due to employee error, malfeasance or other disruptions. In addition, as a provider of products and services to the government, our products andservices may be the targets of cyber attacks that attempted to sabotage or otherwise disable them, or our cybersecurity and other products and servicesultimately may not be able to effectively detect, prevent, or protect against or otherwise mitigate losses from all cyber attacks. Any such breach couldcompromise our networks, creating system disruptions or slowdowns and exploiting security vulnerabilities of our products, and the information stored onour networks could be accessed, publicly disclosed, lost or stolen, which could subject us to liability to our customers, suppliers, business partners and others,could require significant management attention and resources, could result in the loss of business, regulatory actions and potential liability, and could causeus reputational and financial harm. In addition, sophisticated hardware and operating system software and applications that we produce or procure from thirdparties may contain defects in design or manufacture, including "bugs" and other problems that could unexpectedly interfere with the operation of ournetworks. This can be true even for “legacy” products that have been determined to have reached an end of life engineering status but will continue tooperate for a limited amount of time.If an actual or perceived breach of network security occurs in our network or in the network of a customer of our networking products, regardless ofwhether the breach is attributable to our products, the market perception of the effectiveness of our products could be harmed. In addition, the economic coststo us to eliminate or alleviate cyber or other security problems, bugs, viruses, worms, malicious software systems and security vulnerabilities could besignificant and may be difficult to anticipate or measure. Because the techniques used by computer programmers and hackers, many of whom are highlysophisticated and well-funded, to access or sabotage networks change frequently and generally are not recognized until after they are used, we may be unableto anticipate or immediately detect these techniques. This could impede our sales, manufacturing, distribution or other critical functions, which couldadversely affect our business.31 Market conditions and changes in the industry could lead to discontinuation of our products or businesses resulting in asset impairments.In response to changes in industry and market conditions, we may be required to strategically realign our resources and consider restructuring,disposing of, or otherwise exiting businesses. Any decision to limit investment in or dispose of or otherwise exit businesses may result in the recording ofspecial charges, such as inventory and technology-related write-offs, workforce reduction costs, charges relating to consolidation of excess facilities, orclaims from third parties who were resellers or users of discontinued products. Our estimates with respect to the useful life or ultimate recoverability of ourcarrying basis of assets, including purchased intangible assets, could change as a result of such assessments and decisions. Although in certain instances, oursupply agreements allow us the option to cancel, reschedule, and adjust our requirements based on our business needs prior to firm orders being placed, ourloss contingencies may include liabilities for contracts that we cannot cancel with contract manufacturers and suppliers. Further, our estimates relating to theliabilities for excess facilities are affected by changes in real estate market conditions.If our products do not effectively inter-operate with our customers’ networks and result in cancellations and delays of installations, our businesscould be harmed.Our products are designed to interface with our customers’ existing networks, each of which have different specifications and utilize multiple protocolstandards and products from other vendors. Many of our customers’ networks contain multiple generations of products that have been added over time asthese networks have grown and evolved. Our products must inter-operate with many or all of the products within these networks as well as future products inorder to meet our customers’ requirements. If we find errors in the existing software or defects in the hardware used in our customers’ networks, we may needto modify our software networking solutions to fix or overcome these errors so that our products will inter-operate and scale with the existing software andhardware, which could be costly and could negatively affect our business, financial condition, and results of operations. In addition, if our products do notinter-operate with those of our customers’ networks, demand for our products could be adversely affected or orders for our products could be canceled. Thiscould hurt our operating results, damage our reputation, and seriously harm our business and prospects. Our revenues may decline as a result of changes inpublic funding of educational institutions.A portion of our revenues comes from sales to both public and private K-12 educational institutions. Public schools receive funding from local taxrevenue, and from state and federal governments through a variety of programs, many of which seek to assist schools located in underprivileged or rural areas.The funding for a portion of our sales to educational institutions comes from a federal funding program known as the E-Rate program. E-Rate is a program ofthe Federal Communications Commission that subsidizes the purchase of approved telecommunications, Internet access, and internal connection costs foreligible public educational institutions. The E-Rate program, its eligibility criteria, the timing and specific amount of federal funding actually available andwhich Wi-Fi infrastructure and product sectors will benefit, are uncertain and subject to final federal program approval and funding appropriation continuesto be under review by the Federal Communications Commission, and we cannot assure that this program or its equivalent will continue, and as a result, ourbusiness may be harmed. Furthermore, if state or local funding of public education is significantly reduced because of legislative or policy changes or byreductions in tax revenues due to changing economic conditions, our sales to educational institutions may be negatively impacted by these changedconditions. Any reduction in spending on information technology systems by educational institutions would likely materially and adversely affect ourbusiness and results of operations. This is a specific example of the many factors which add additional uncertainty to our future revenue from our educationend-customers.Our headquarters and some significant supporting businesses are located in Northern California and other areas subject to natural disasters thatcould disrupt our operations and harm our business.Our corporate headquarters are located in Silicon Valley in Northern California. Historically, this region as well as our R&D centers in North Carolinaand New Hampshire have been vulnerable to natural disasters and other risks, such as earthquakes, fires, floods and tropical storms, which at times havedisrupted the local economy and posed physical risks to our property. We have contract manufacturers located in Taiwan where similar natural disasters andother risks may disrupt the local economy and pose physical risks to our property and the property of our contract manufacturer.In addition, the continued threat of terrorism and heightened security and military action in response to this threat, or any future acts of terrorism, maycause further disruptions to the economies of the United States and other countries. If such disruptions result in delays or cancellations of customer orders forour products, our business and operating results will suffer.We currently do not have redundant, multiple site capacity in the event of a natural disaster, terrorist act or other catastrophic event. In the event ofsuch an occurrence, our business would suffer. Item 1B. Unresolved Staff CommentsNone.32 Item 2. PropertiesOur corporate headquarters is located in San Jose, California where we currently lease approximately 185,000 square feet of space under a leaseagreement that expires in fiscal year 2027.In addition to our headquarters in San Jose, we lease additional sites in the United States, including facilities in Salem, New Hampshire andMorrisville/Raleigh, North Carolina for research and development, sales and marketing and administrative offices. Outside the United States, we also leaseoffice space in various other international geographic locations for research and development, sales and service personnel and administration in OtherAmericas, EMEA and APAC, including Ottawa, Canada, Bangalore, India, Chennai, India, Markham, Canada, Reading, United Kingdom and Shannon,Ireland.As of June 30, 2018, we have leased approximately 1.0 million square feet of space with various expiration dates between fiscal year 2019 and fiscal2028. We believe that our current facilities are sustainable and adequate to meet our current needs and the productive capacity of such facilities issubstantially being utilized or we have plans to utilize such capacity.Item 3.

In the course of operating our business, we routinely make decisions as to thetiming of the payment of invoices, the collection of receivables, the manufacturing and shipment of products, the fulfillment of orders, the purchase ofsupplies, and the building of inventory and service parts, among other matters. Each of these decisions has some impact on the financial results for any givenperiod. In making these decisions, we consider various factors including contractual obligations, customer satisfaction, competition, internal and externalfinancial targets and expectations, and financial planning objectives. For further information about our critical accounting policies and estimates, see“Critical Accounting Policies and Estimates” section included in this “Management's Discussion and Analysis of Financial Condition and Results ofOperations.”Extreme Networks, Inc., together with its subsidiaries (collectively referred to as “Extreme” and as “we”, “us” and “our”) is a leading provider ofnetwork infrastructure equipment and offers related maintenance contracts for extended warranty and maintenance to our enterprise, data center and serviceprovider customers.

We consolidated our existing workforce fromour previous headquarters with employees assumed from Zebra to the Via del Oro site and exited the Rio Robles site on January 31, 2017. Due to our movefrom the Rio Robles facility and abandonment of all leasehold improvements, we accelerated the amortization of the remaining leasehold improvements forthis site over the shortened service period such that the leasehold improvements were fully amortized on the cease-use date. We recorded acceleratedamortization expense for the year ended June 30, 2017 of $2.6 million which is reflected in “Restructuring and related charges, net of reversals” in theconsolidated statements of operations. 43 We entered into a sublease agreement related to our Rio Robles facility during the third quarter of fiscal 2017 for the remaining duration of the lease.The sublease resulted in adjustments to the prior estimates for the amount of sublease payments, timing of sublease activities and real estate commissionsassociated with the sublease. The net adjustments, including modifications to our future obligations for non-cancellable lease payments and related futuresubleasing income resulted in additional charges of $2.0 million during fiscal 2017. The excess facilities payments will continue through fiscal year 2023.In anticipation of the acquisitions of Campus Fabric Business and Data Center Business in fiscal 2018, we reoccupied the majority of the previouslyexited space at our Salem, New Hampshire location during our fiscal fourth quarter to accommodate the growth in headcount and lab facility requirements.This action resulted in a reversal of prior restructuring expense accruals of $1.3 million.We also implemented a reduction-in-force which affected 90 employees. We recorded severance and benefits charges of $5.6 million during the yearended June 30, 2017. Cash payments of $3.8 million were made by June 30, 2017 with the remainder paid by the end of the second quarter of fiscal 2018.Fiscal year 2016During fiscal 2016, we incurred $11.0 million of restructuring charges. Excess facilities charges included accrued lease costs pertaining to theestimated future obligations for non-cancelable lease payments for excess facilities and contract termination charges of $5.4 million, acceleration ofdepreciation of leasehold improvements of $4.5 million, professional fees of $1.0 million and other expenses of $0.1 million.Significant restructuring charges incurred during 2016, by location, included $1.8 million of charges for excess facilities pertaining to the estimatedfuture obligations for non-cancelable lease payments at Rio Robles. This represented 39% of the San Jose leased space. We amended our facility lease at ourNorth Carolina location and exited excess space while recording $4.1 million of charges, which included $3.1 million in accelerated depreciation ofleasehold improvements. This action represented 36% of the North Carolina location lease space. We recorded $4.4 million of charges for excess facilities atour Salem location, which included $1.3 million in accelerated depreciation of leasehold improvements. This action represented 27% of the Salem leasespace. Amortization of IntangiblesDuring fiscal 2018, 2017 and 2016, we recorded $8.7 million, $8.7 million and $17.0 million, respectively, of amortization expenses in operatingexpenses primarily for certain intangibles related to the acquisitions of the Campus Fabric, Data Center and WLAN Businesses and Enterasys. The loweramortization expense since fiscal 2017 was due to the Enterasys intangible assets becoming fully amortized during fiscal 2017.Interest IncomeInterest income was $2.8 million, $0.7 million and $0.1 million in fiscal years 2018, 2017 and 2016, respectively, representing an increase of $1.9million in fiscal 2018 from fiscal 2017 and an increase of $0.6 million in fiscal 2017 from fiscal 2016. The increase in fiscal 2018 and 2017 was due toaccretion of interest on a long-term note receivable acquired from the WLAN Business as well as increased interest income on cash balances due to risingmarket interest rates.Interest ExpenseWe had $13.9 million, $4.1 million and $3.1 million of interest expense for fiscal 2018, 2017 and 2016, respectively. The increase in interest expensein fiscal 2018 was primarily in connection with the increased balance of our Credit Facility due to the acquisitions of the WLAN, Campus Fabric and DataCenter Businesses and accretion of interest expense of $3.1 million associated with the contingent consideration obligations. In addition, we recorded a lossfrom debt extinguishment of $1.2 million in fiscal 2018 in connection with our Credit Agreement entered on May 1, 2018. The increase in interest expensefor fiscal 2017 was related to our increased borrowings to finance the WLAN Business acquisition in October 2016.Other Income (Expense), netWe incurred other income of $2.6 million, other expense of less than $0.1 million and other income of $1.0 million in fiscal 2018, 2017 and 2016,respectively. The income for fiscal 2018 was primarily driven by a gain of $4.0 million due to the sale of equity investments, partially offset by foreignexchange losses. The expense in fiscal 2017 and income in fiscal 2016 were primarily due to foreign exchange gains from the revaluation of certain assetsand liabilities denominated in foreign currencies into U.S. Dollars.Provision for Income TaxesWe are subject to income taxes in the United States and numerous foreign jurisdictions. Our effective tax rate differs from the newly enacted U.S.federal statutory rate of 21% primarily due to the impact of state taxes, foreign operations, the full valuation of our deferred tax assets in the U.S. and certainforeign jurisdictions and for our fiscal year ended June 30, 2018, the phase in of the new tax rate making our U.S. rate for this particular tax year 28%. For thefiscal years ended June 30, 2018, 2017 and 2016, we recorded income tax provisions of $0.1 million, $4.3 million and $4.3 million, respectively.44 For fiscal 2018, our tax provision primarily related to taxes on our foreign operations offset by two significant tax benefits resulting from Tax Reformand restructuring of our foreign operations. Income tax provision of $6.7 million consisted of taxes on the income of our foreign subsidiaries as well as taxexpense associated with the establishment of a U.S. deferred tax liability for amortizable goodwill. Partially offsetting the tax provision is a tax benefit of$3.1 million resulting from the reduction of the U.S. Federal tax rate from 35% to 21% applied to our deferred tax liability related to amortizable goodwill asrequired by the recently enacted U.S. tax legislation as well as a tax benefit resulting from the impairment of a lease acquired from Avaya in Canada.Additionally, we recorded a tax benefit resulting from the restructuring of our foreign operations of $3.4 million.For fiscal 2017 and 2016, the majority of our tax provision related to taxes on our foreign operations as well as state taxes due to the full valuationallowance on our U.S. and certain foreign deferred tax assets.For a full reconciliation of our effective tax rate to the U.S. federal statutory rate and for further explanation of our provisions for income taxes, seeNote 15. Income Taxes, for additional information.Critical Accounting Policies and EstimatesOur significant accounting policies are more fully described in Note 3 of Notes to Consolidated Financial Statements included in Item 8 of thisAnnual Report on Form 10-K. The preparation of consolidated financial statements in accordance with generally accepted accounting principles requiresmanagement to make estimates, assumptions and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assetsand liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the period reported. By theirnature, these estimates, assumptions and judgments are subject to an inherent degree of uncertainty. We base our estimates, assumptions and judgments onhistorical experience, market trends and other factors that are believed to be reasonable under the circumstances. Estimates, assumptions and judgments arereviewed on an ongoing basis and the effects of revisions are reflected in the consolidated financial statements in the period they are determined to benecessary. Actual results may differ from these estimates under different assumptions or conditions. We believe the critical accounting policies stated below,among others, affect our more significant judgments and estimates used in the preparation of our consolidated financial statements.Revenue RecognitionWe account for revenue in accordance with Topic 606, Revenue from Contracts with Customers, which we adopted on July 1, 2017, using the fullretrospective method. We derive the majority of our revenue from sales of our networking equipment, with the remaining revenue generated from service feesrelating to maintenance contracts, professional services, and training for our products. We sell our products and maintenance contracts direct to customersand to partners in two distribution channels, or tiers. The first tier consists of a limited number of independent distributors that stock our products and sellprimarily to resellers. The second tier of the distribution channel consists of a non-stocking distributors and value-added resellers that sell directly to end-users. Products and services may be sold separately or in bundled packages. We consider customer purchase orders, which in some cases are governed by master sales agreements, to be the contracts with a customer. For eachcontract, we consider the promise to transfer products and services, each of which are distinct, to be the identified performance obligations. In determining thetransaction price, we evaluate whether the price is subject to refund or adjustment to determine the net consideration to which we expect to be entitled.For all of our sales and distribution channels, revenue is recognized when control of the product is transferred to the customer (i.e., when ourperformance obligation is satisfied), which typically occurs at shipment for product sales. Revenue from maintenance contracts is recognized over time as ourperformance obligations are satisfied. This is typically the contractual service period, which ranges from one to three years. For product sales to our value-added resellers, non-stocking distributors and end-user customers, we generally do not grant return privileges, except for defective products during thewarranty period, nor do we grant pricing credits. Sales incentives and other programs that we may make available to these customers are considered to be aform of variable consideration and we maintain estimated accruals and allowances using the expected value method. Sales to stocking distributors are made under terms allowing certain price adjustments and limited rights of return (known as “stock rotation”) of ourproducts held in their inventory. Stock rotation rights grant the distributor the ability to return certain specified amounts of inventory. Stock rotationadjustments are an additional form of variable consideration and are estimated using the expected value method based on historical return rates. Frequently,distributors need to sell at a price lower than the contractual distribution price in order to win business, and submit rebate requests for Company pre-approvalprior to selling the product through at the discounted price. At the time the distributor invoices our customer or soon thereafter, the distributor submits arebate claim to us to adjust the distributor’s cost from the contractual price to the pre-approved lower price. After we verify that the claim was pre-approved, acredit memo is issued to the distributor for the rebate claim. In determining the transaction price, we consider these rebate adjustments to be variableconsideration. Such price adjustments are estimated using the expected value method based on an analysis of actual claims, at the distributor level over aperiod of time considered adequate to account for current pricing and business trends.45 Performance Obligations. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit ofaccount in Topic 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, theperformance obligation is satisfied. Certain of our contracts have multiple performance obligations, as the promise to transfer individual goods or services isseparately identifiable from other promises in the contracts and, therefore, is distinct. For contracts with multiple performance obligations, we allocate thecontract’s transaction price to each performance obligation based on our relative standalone selling price. The stand-alone selling prices are determinedbased on the prices at which we separately sell these products. For items that are not sold separately, we estimate the stand-alone selling prices using the bestestimated selling price approach. Our performance obligations are satisfied at a point in time or over time as work progresses. Substantially all of our product sales revenues as reflectedon the consolidated statements of operations for the years ended June 30, 2018, 2017 and 2016 are recognized at a point in time. Substantially all of ourservice revenue is recognized over time. For revenue recognized over time, we use an input measure, days elapsed, to measure satisfaction of the performanceobligation. Contract Balances. The timing of revenue recognition, billings and cash collections results in billed accounts receivable and deferred revenue in theconsolidated balance sheets. Services provided under our renewable support arrangements are billed in accordance with agreed-upon contractual terms,which are typically at periodic intervals (e.g., quarterly or annually). We sometimes receive payments from our customers in advance of services beingprovided, resulting in deferred revenues. These liabilities are reported on the consolidated balance sheets on a contract-by-contract basis at the end of eachreporting period.Contract Costs. We recognize the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets thatwe otherwise would have recognized is one year or less. Management expects that commission fees paid to sales representative as a result of obtainingservice contracts and contract renewals are recoverable and therefore we capitalized them as contract costs. Capitalized commission fees are amortized on astraight-line basis over the average period of service contracts of approximately three years, and are included in “Sales and marketing” in the accompanyingconsolidated statements of operations. Business CombinationsWe apply the acquisition method of accounting for business combinations. Under this method of accounting, all assets acquired and liabilitiesassumed are recorded at their respective fair values at the date of the completion of the transaction. Determining the fair value of assets acquired andliabilities assumed requires management’s judgment and often involves the use of significant estimates and assumptions, including assumptions with respectto future cash inflows and outflows, discount rates, intangibles and other asset lives, among other items. Fair value is defined as the price that would bereceived to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). Marketparticipants are assumed to be buyers and sellers in the principal (most advantageous) market for the asset or liability. Additionally, fair value measurementsfor an asset assume the highest and best use of that asset by market participants. As a result, we may have been required to value the acquired assets at fairvalue measures that do not reflect its intended use of those assets. Use of different estimates and judgments could yield different results. Any excess of thepurchase price over the fair value of the net assets acquired is recognized as goodwill. If the fair value of net assets acquired exceeds the fair value of purchaseprice, a gain on bargain purchase is recognized in the statements of operations. Although we believe the assumptions and estimates we have made arereasonable and appropriate, they are based in part on historical experience and information that may be obtained from the management of the acquiredcompany and are inherently uncertain. Unanticipated events and circumstances may occur that may affect the accuracy or validity of such assumptions,estimates or actual results. As a result, during the measurement period, which may be up to one year from the acquisition date, we may record adjustments tothe assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determinationof the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements ofoperations.Inventory Valuation and Purchase CommitmentsWe write down inventory and record purchase commitment liabilities for estimated excess and obsolete inventory equal to the difference between thecost of inventory and the estimated market value based upon the forecast of future product demand, product transition cycles, and market conditions. Anysignificant unanticipated changes in demand or technological development could have a significant impact on the value of our inventory and purchasecommitments and our reported results. If actual market conditions are less favorable than those projected, additional inventory write-downs, purchasecommitment liabilities, and charges against earnings may be required.46 New Accounting PronouncementsSee Note 2. Summary of Significant Accounting Policies, in the accompanying consolidated financial statements for a full description of newaccounting pronouncements, including the respective expected dates of adoption and effects on results of operations and financial condition.Liquidity and Capital ResourcesThe following summarizes information regarding our cash, investments, and working capital (in thousands): June 30,2018 June 30,2017 Cash and cash equivalents $121,139 $130,450 Marketable securities 1,459 — Total cash and investments $122,598 $130,450 Working capital $68,041 $85,637 As of June 30, 2018, our principal sources of liquidity consisted of cash, cash equivalents and investments of $122.6 million, accounts receivable, netof $212.4 million and availability of borrowings from the New Revolving Facility of $28.7 million. We anticipate that our principal uses of cash for fiscal2019 will be purchases of finished goods inventory from our contract manufacturers, payroll, repayments of debt and related interest, and other operatingexpenses related to the development, marketing of our products and purchases of property and equipment. We believe that our cash, cash equivalents,investments and cash flows from operations along with the availability of additional borrowings from our Credit Agreement, will be sufficient to fund ourprincipal uses of cash for at least the next 12 months.On May 1, 2018, the Company terminated the Amended and Restated Credit Agreement dated October 28, 2016, by and among the Company, asborrower, Silicon Valley Bank, as administrative agent, and the financial institutions that were a party thereto as lenders.On May 1, 2018, the Company entered into a Credit Agreement (the “Credit Agreement”), by and among the Company, as borrower, BMO HarrisBank N.A., as an issuing lender and swingline lender, Bank of Montreal, as administrative and collateral agent, and the financial institutions or entities thatare a party thereto as lenders. The Credit Agreement provides for i) a $40 million five-year revolving credit facility (the “New Revolving Facility”), ii) a$190 million five-year term loan (the “New Term Loan”) and, iii) an uncommitted additional incremental loan facility in the principal amount of up to $100million (“New Incremental Facility”). On May 1, 2018, the Company borrowed $200 million under the Credit Agreement in order to pay off the existingdebt, as noted above and for general corporate purposes.Borrowings under the Credit Agreement will bear interest, at the Company’s election, as of May 1, 2018, at a rate per annum equal to LIBOR plus1.50% to 2.75%, or the adjusted base rate plus 0.50% to 1.75%, based on the Company’s consolidated leverage ratio. In addition, the Company is required topay a commitment fee of between 0.25% and 0.40% quarterly (currently 0.35%) on the unused portion of the New Revolving Facility, also based on theCompany’s consolidated leverage ratio. Principal installments are payable on the New Term Loan in varying percentages quarterly starting September 30,2018 and to the extent not previously paid, all outstanding balances are to be paid at maturity. The obligations under the Credit Agreement is secured bysubstantially all of the Company’s assets.Financial covenants under the Credit Agreement require the Company to maintain a minimum consolidated fixed charge and consolidatedleverage ratio at the end of each fiscal quarter through maturity. The Credit Agreement also includes covenants and restrictions that limit, among otherthings, the Company’s ability to incur additional indebtedness, create liens upon any of its property, merge, consolidate or sell all or substantially all of itsassets. The Credit Agreement also includes customary events of default which may result in acceleration of the outstanding balance. At June 30, 2018, wewere in compliance with the covenants of the Credit Agreement.47 Key Components of Cash Flows and LiquidityA summary of the sources and uses of cash and cash equivalents is as follows (in thousands): Year Ended June 30,2018 June 30,2017 June 30,2016 Net cash provided by operating activities $19,043 $59,283 $30,366 Net cash used in investing activities (132,471) (71,752) (5,327)Net cash provided by (used in) financing activities 104,746 48,708 (6,738)Foreign currency effect on cash (629) 89 (404)Net (decrease) increase in cash and cash equivalents $(9,311) $36,328 $17,897Cash and cash equivalents were $121.1 million at June 30, 2018, representing a decrease of $9.3 million from $130.5 million at June 30, 2017. Cashand cash equivalents decreased primarily due to cash used in investing activities of $132.5 million mainly for the acquisitions of the Campus Fabric and DataCenter Businesses and capital expenditures, partially offset by cash provided by financing activities of $104.7 million as a result of additional borrowings forthe acquisitions and cash provided by operations of $19.0 million.Cash and cash equivalents were $130.5 million at June 30, 2017, representing an increase of $36.4 million from $94.1 million at June 30, 2016.

Quantitative and Qualitative Disclosures About Market RiskInterest Rate SensitivityOur exposure to market risk for changes in interest rates relates primarily to our financial investments and debt. We usually invest our cash ininvestments with short maturities or with frequent interest reset terms. Accordingly, our interest income fluctuates with short-term market conditions. As ofJune 30, 2018, we did not have any financial investments that were exposed to interest rate risk. DebtAt certain points in time we are exposed to the impact of interest rate fluctuations, primarily in the form of variable rate borrowings from the CreditAgreement which is fully described in Note 8. Debt, of our Notes to the Consolidated Financial Statements. At June 30, 2018 we had $200.0 million of debtoutstanding, all of which was from the Credit Agreement. Through the end of our fiscal year, the average daily outstanding amount was $181.1 million witha high of $200.0 million and a low of $93.7 million. The following table presents hypothetical changes in interest expense for the year ended June 30, 2018, on the outstanding Credit Agreement,borrowings as of June 30, 2018, that are sensitive to changes in interest rates (in thousands): Change in interest expense given a decrease ininterest rate of X bps* Outstandingdebt as of Change in interest expense given an increase ininterest rate of X bps (100 bps) (50 bps) June 30, 2018 100 bps 50 bps $(500) $(250) $200,000 $500 $250 *Underlying benchmark interest rate was 2.0 % as of June 30, 2018.Exchange Rate SensitivityA majority of our sales and our expenses are denominated in United States Dollars. While we conduct sale transactions and incur certain operatingexpenses in foreign currencies and expect to continue to do so, we do not anticipate that foreign exchange gains or losses will be significant, in part becauseof our foreign exchange risk management process discussed below.Foreign Exchange Forward ContractsWe record all derivatives on the balance sheet at fair value. Changes in the fair value of derivatives are recognized in earnings as Other income (loss),net. From time to time, we enter into foreign exchange forward contracts to mitigate the effect of gains and losses generated by the foreign currency forecasttransactions related to certain operating expenses and re-measurement of certain assets and liabilities denominated in foreign currencies. These derivatives donot qualify as hedges. Changes in the fair value of these foreign exchange forward contracts are offset largely by re-measurement of the underlying assets andliabilities. At June 30, 2018 and 2017, we had outstanding foreign currency forward contracts with a notional value of $5.0 million and $6.7 millionrespectively.Foreign currency transaction gains and losses from operations were losses of $1.2 million and $0.7 million in fiscal years 2018 and 2017, respectivelyand gains of $1.3 million in fiscal 2016. 50 Item 8.

We also have audited the Company’s internal control overfinancial reporting as of June 30, 2018, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee ofSponsoring Organizations of the Treadway Commission. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of June30, 2018 and 2017, and the results of its operations and its cash flows for each of the years in the three-year period ended June 30, 2018, in conformity withU.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control over financialreporting as of June 30, 2018, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of SponsoringOrganizations of the Treadway Commission. During the year ended June 30, 2018, the Company completed its acquisitions of the fabric-based secure networking solutions and network security solutionsbusiness of Avaya Inc., the data center business of Brocade Communication Systems, Inc., and the capital financing business from Broadcom Corporation,(collectively, the “Acquisitions”) and management excluded from its assessment of the effectiveness of the Company’s internal control over financialreporting as of June 30, 2018, the Acquisitions’ internal control over financial reporting associated with total assets of 20% and total revenues of 33%included in the consolidated financial statements of the Company as of and for the year ended June 30, 2018. Our audit of internal control over financialreporting of the Company also excluded an evaluation of the internal control over financial reporting of the Acquisitions. Change in Accounting PrincipleAs discussed in Note 3 to the consolidated financial statements, the Company has changed its method of accounting for revenue from contracts withcustomers for each of the years in the three-year period ended June 30, 2018 due to the adoption of ASU 2014-09, Revenue from Contracts with Customers(Topic 606).Basis for OpinionsThe Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting,and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on InternalControl over Financial Reporting under Item 9A. Our responsibility is to express an opinion on the Company’s consolidated financial statements and anopinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public CompanyAccounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federalsecurities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonableassurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internalcontrol over financial reporting was maintained in all material respects.Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financialstatements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis,evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles usedand significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internalcontrol over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weaknessexists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performingsuch other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.Definition and Limitations of Internal Control Over Financial Reporting52 A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reportingand the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal controlover financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairlyreflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permitpreparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are beingmade only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention ortimely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation ofeffectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliancewith the policies or procedures may deteriorate. /s/ KPMG LLPWe have served as the Company’s auditor since 2010.Raleigh, North CarolinaAugust 29, 2018 53 EXTREME NETWORKS, INC.CONSOLIDATED BALANCE SHEETS(In thousands, except per share amounts) June 30,2018 June 30,2017 (As adjusted) ASSETS Current assets: Cash and cash equivalents $121,139 $130,450 Accounts receivable, net of allowance for doubtful accounts of $1,478 and $1,190 at June 30, 2018 and 2017,respectively 212,423 93,115 Inventories 63,867 47,410 Prepaid expenses and other current assets 30,484 27,867 Total current assets 427,913 298,842 Property and equipment, net 78,519 30,240 Intangible assets, net 77,092 25,337 Goodwill 139,082 80,216 Other assets 47,642 25,065 Total assets $770,248 $459,700 LIABILITIES AND STOCKHOLDERS’ EQUITY Current liabilities: Current portion of long-term debt $9,007 $12,280 Accounts payable 75,689 31,587 Accrued compensation and benefits 50,351 42,662 Accrued warranty 12,807 10,584 Deferred revenue 130,865 79,048 Other accrued liabilities 81,153 37,044 Total current liabilities 359,872 213,205 Deferred revenue, less current portion 43,660 25,293 Long-term debt, less current portion 188,749 80,422 Deferred income taxes 6,135 6,576 Other long-term liabilities 59,100 8,526 Commitments and contingencies (Note 9) Stockholders’ equity: Convertible preferred stock, $.001 par value, issuable in series, 2,000 shares authorized; none issued — — Common stock, $.001 par value, 750,000 shares authorized; 116,124 shares issued and outstanding at June 30, 2018 and 110,925 shares issued and outstanding at June 30, 2017 116 111 Additional paid-in-capital 942,397 909,155 Accumulated other comprehensive loss (1,703) (2,302)Accumulated deficit (828,078) (781,286)Total stockholders’ equity 112,732 125,678 Total liabilities and stockholders’ equity $770,248 $459,700 See accompanying notes to consolidated financial statements. 54 EXTREME NETWORKS, INC.CONSOLIDATED STATEMENTS OF OPERATIONS(In thousands, except per share amounts) Year Ended June 30,2018 June 30,2017 June 30,2016 (As adjusted) (As adjusted) Net revenues: Product $764,455 $460,425 $386,909 Service 218,687 146,659 132,925 Total net revenues 983,142 607,084 519,834 Cost of revenues: Product 357,062 220,221 205,569 Service 91,563 55,906 48,862 Total cost of revenues 448,625 276,127 254,431 Gross profit: Product 407,393 240,204 181,340 Service 127,124 90,753 84,063 Total gross profit 534,517 330,957 265,403 Operating expenses: Research and development 183,877 93,724 78,721 Sales and marketing 267,107 162,626 149,900 General and administrative 50,988 37,864 37,675 Acquisition and integration costs, net of bargain purchase gain 53,900 13,105 1,145 Restructuring and related charges, net of reversals 8,140 8,896 10,990 Amortization of intangibles 8,715 8,702 17,001 Total operating expenses 572,727 324,917 295,432 Operating (loss) income (38,210) 6,040 (30,029)Interest income 2,847 689 113 Interest expense (13,923) (4,086) (3,098)Other income (expense), net 2,639 (47) 987 (Loss) income before income taxes (46,647) 2,596 (32,027)Provision for income taxes 145 4,340 4,336 Net loss $(46,792) $(1,744) $(36,363)Basic and diluted net loss per share: Net loss per share -

Description of Business and Basis of PresentationExtreme Networks, Inc., together with its subsidiaries (collectively referred to as “Extreme” or “the Company”) is a leader in providing software-drivennetworking solutions for enterprise customers. The Company conducts its sales and marketing activities on a worldwide basis through distributors, resellersand the Company’s field sales organization. Extreme was incorporated in California in 1996 and reincorporated in Delaware in 1999.Effective July 1, 2017, the Company adopted the requirements of Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts withCustomers (Topic 606). All amounts and disclosures set forth in this Form 10-K have been updated to comply with the new standards, as indicated by the “asadjusted” footnote.Fiscal YearThe Company uses a fiscal calendar year ending on June 30. All references herein to “fiscal 2018” or “2018”; “fiscal 2017” or “2017”; “fiscal 2016”or “2016” represent the fiscal years ending 2018, 2017 and 2016, respectively.Principles of ConsolidationThe consolidated financial statements include the accounts of Extreme Networks and its wholly-owned subsidiaries. All inter-company accounts andtransactions have been eliminated.The Company predominantly uses the United States Dollar as its functional currency. The functional currency for certain of its foreign subsidiaries isthe local currency. For those subsidiaries that operate in a local currency functional environment, all assets and liabilities are translated to United StatesDollars at current month end rates of exchange; and revenue and expenses are translated using the monthly average rate.Accounting EstimatesThe preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United Statesrequires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual resultscould differ materially from these estimates.2. Summary of Significant Accounting PoliciesRevenue RecognitionThe Company derives revenues primarily from sales of its networking equipment, with the remaining revenue generated from service fees relating tomaintenance contracts, professional services, and training for the products. The Company recognizes revenues when control of promised goods or services istransferred to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services.See Note 3. Revenues, for further discussion.Cash, Cash Equivalents and Marketable SecuritiesThe Company considers highly liquid investments with maturities of three months or less at the date of purchase to be cash equivalents. Marketablesecurities are recorded in “Prepaid expense and other current assets” in the accompanying consolidated balance sheet as these are publicly-traded equitysecurities with maturities of greater than three months, but less than one year at the balance sheet date. Marketable securities are classified as available-for-sale and reported at fair value with unrealized gains and losses included, net of tax, in accumulated other comprehensive loss, a component of stockholders’equity. Realized gains and losses and declines in the value of available-for-sale securities determined to be other than temporary are included in other income(expense), net. The cost of securities sold is determined based on the specific identification method.Allowance for Product ReturnsThe Company provides an allowance for product returns based on its historical returns, analysis of credit memo data and its return policies. Theallowance includes the estimates for product allowances from end customers as well as stock rotations and other returns from the Company’s stockingdistributors. The allowance for product returns is a reduction of accounts receivable. If the historical data that the Company uses to calculate the estimatedproduct returns and allowances does not properly reflect actual levels of product returns, these estimates will be revised, resulting in an impact on netrevenue. The allowance for product returns estimate is also impacted by the timing of the actual product return from the customer.59EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Allowance for Doubtful AccountsThe Company maintains an allowance for doubtful accounts which reflects its best estimate of potentially uncollectible trade receivables. Theallowance consists of both specific and general reserves. The Company continually monitors and evaluates the collectability of its trade receivables based ona combination of factors. It records specific allowances for bad debts in general and administrative expense when it becomes aware of a specific customer’sinability to meet its financial obligation to the Company, such as in the case of bankruptcy filings or deterioration of financial position. Estimates are used indetermining the allowances for all other customers based on factors such as current trends in the length of time the receivables are past due and historicalcollection experience. The Company mitigates some collection risk by requiring most of its customers in the Asia-Pacific region, excluding Japan andAustralia, to pay cash in advance or secure letters of credit when placing an order with the Company.InventoriesThe Company values its inventory at lower of cost or net realizable value. Cost is computed using standard cost, which approximates actual cost, on afirst-in, first-out basis. The Company has established inventory allowances when conditions exist that suggest that inventory may be in excess of anticipateddemand based upon assumptions about future demand or is obsolete. At the point of the loss recognition, a new, lower-cost basis for that inventory isestablished, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. Previouslywritten down or obsolete inventory subsequently sold has not had a material impact on gross margin for any of the periods presented.Long-Lived AssetsLong-lived assets include (a) property and equipment, (b) goodwill and intangible assets, and (c) other assets. Property and equipment and definite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets or assetgroups may not be recoverable. If such facts and circumstances exist, the Company assesses the recoverability of these assets by comparing the projectedundiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts.Impairments, if any, are based on the excess of the carrying amount over the fair value of those assets.(a) Property and Equipment, NetProperty and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization is computed using thestraight-line method over the estimated useful lives of the assets. Estimated useful lives of one to four years are used for computer equipment and software.Estimated useful lives of three to seven years are used for office equipment, furniture and fixtures. Depreciation and amortization of leasehold improvementsis computed using the lesser of the useful life or lease terms (ranging from two to ten years).(b) Goodwill and Intangible AssetsGoodwill and indefinite-lived intangible assets are generated as a result of business combinations. The Company’s indefinite-lived intangible assetsare comprised of acquired in-process research and development (“IPR&D”), which is treated as indefinite until the completion or abandonment of theassociated research and development effort. During the development period, the Company conducts an IPR&D impairment test at least annually or wheneverevents or changes in facts and circumstances indicate that it is more likely than not that the IPR&D is impaired. Events which might indicate impairmentinclude, but are not limited to, adverse cost factors, deteriorating financial performance, strategic decisions made in response to economic, market, andcompetitive conditions, the impact of the economic environment on the Company and its customer base, and/or other relevant events such as changes inmanagement, key personnel, litigations, or customers. Management did not identify any triggering events for any periods presented. Intangible assets otherthan acquired IPR&D are not considered to have an indefinite life and are amortized over their useful lives. The Company reevaluates the estimatedremaining useful life of acquired intangible assets whenever events or changes in circumstances indicate a revision to the remaining period of amortizationmight be necessary. The carrying amounts of these assets are reviewed for impairment whenever events or changes in circumstances indicate that the carryingvalue of these assets may not be recoverable.60EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Goodwill is calculated as the excess of the purchase price over the fair value of net tangible and identifiable intangible assets acquired. Goodwill isnot amortized, but rather is tested for impairment at least annually or more frequently if indicators of impairment are present. The Company performs itsannual goodwill impairment analysis as of the first day of the fourth quarter of each year. The Company adopted ASU 2017-04, Intangibles—Goodwill andOther (Topic 350): Simplifying the Test for Goodwill Impairment in fiscal 2018, which eliminated step two from the goodwill impairment test. In assessingimpairment on goodwill, the Company bypasses the qualitative assessment and proceed directly to performing the quantitative evaluation of the fair value ofthe reporting unit, to compare against the carrying value of the reporting unit. A goodwill impairment charge is recognized for the amount by which thereporting unit’s fair value is less than its carrying value. Any loss recognized should not exceed the total amount of goodwill allocated to that reporting unit.Based on the results of the goodwill impairment analyses, the Company determined that no impairment charge needed to be recorded for any periodspresented.(c) Other AssetsOther assets consist primarily of service parts and long-term deposits. The Company holds service parts to support customers who have purchasedservice contracts with a hardware replacement element, as well as to support its warranty program. The Company reduces the carrying value of service parts tonet realizable value based on expected quantities needed to satisfy contractual service requirements of customers.Business CombinationsThe Company applies the acquisition method of accounting for business combinations. Under this method of accounting, all assets acquired andliabilities assumed are recorded at their respective fair values at the date of the acquisition. Determining the fair value of assets acquired and liabilitiesassumed requires management’s judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to futurecash inflows and outflows, discount rates, intangibles and other asset lives, among other items. Fair value is defined as the price that would be received to sellan asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Market participants are assumed to bebuyers and sellers in the principal (most advantageous) market for the asset or liability. Additionally, fair value measurements for an asset assume the highestand best use of that asset by market participants. As a result, the Company may be required to value the acquired assets at fair value measures that do notreflect its intended use of those assets. Use of different estimates and judgments could yield different results.Any excess of the purchase price over the fair value of the net assets acquired is recognized as goodwill. If the fair value of net assets acquired exceedsthe fair value of purchase price, a gain on bargain purchase is recognized within the statements of operations. Although the Company believes theassumptions and estimates it has made are reasonable and appropriate, they are based in part on historical experience and information that may be obtainedfrom the management of the acquired company and are inherently uncertain. During the measurement period, which may be up to one year from theacquisition date, the Company may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill for facts andconsiderations that were known at the acquisition date. Upon the conclusion of the measurement period or final determination of the values of assets acquiredor liabilities assumed, whichever comes first, any subsequent adjustments are recorded within the Company’s consolidated statements of operations.Deferred RevenueDeferred revenue represents amounts for (i) deferred maintenance and support revenue and (ii) other deferred revenue including professional servicesand training when the revenue recognition criteria have not been met. Product Warranties and GuaranteesNetworking products may contain undetected hardware or software errors when new products or new versions or updates of existing products arereleased to the marketplace. The Company’s standard hardware warranty period is typically 12 months from the date of shipment to end-users and 90 days forsoftware. For certain access products, the Company offers a limited lifetime hardware warranty commencing on the date of shipment from the Company andending five (5) years following the Company’s announcement of the end of sale of such product. Upon shipment of products to its customers, the Companyestimates expenses for the cost to repair or replace products that may be returned under warranty and accrue a liability in cost of product revenue for thisamount. The determination of the Company’s warranty requirements is based on actual historical experience with the product or product family, estimates ofrepair and replacement costs and any product warranty problems that are identified after shipment. The Company estimates and adjusts these accruals at eachbalance sheet date in accordance with changes in these factors.61EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) In the normal course of business to facilitate sales of its products, the Company indemnifies its resellers and end-user customers with respect to certainmatters. The Company has agreed to hold the customer harmless against losses arising from a breach of intellectual property infringement or other claimsmade 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 notpossible to estimate the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims andthe unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have nothad a material impact on its operating results or financial position.Stock-based CompensationThe Company recognizes compensation expense related to stock-based awards, including stock options, restricted stock units (“RSUs”) and employeestock purchases related to its 2014 Employee Stock Purchase Plan (the “2014 ESPP”), based on the estimated fair value of the award on the grant date, overthe requisite service period. The Company accounts for forfeitures as they occur. The Company calculates the fair value of stock option using the Black-Scholes-Merton option valuation model. The fair value of RSUs represents the closing stock price of the Company’s common stock on the grant date. TheCompany calculates the fair value of share purchase option under the 2014 ESPP using the Black-Scholes-Merton option valuation model.The Company grants certain employees performance-based stock options and RSUs. The performance metrics include company-wide financialperformance and/or market conditions. For awards that include performance conditions, no compensation cost is recognized until the performance goals areprobable of being met, at which time the cumulative compensation expense from the service inception date would be recognized. For awards that containmarket conditions, compensation expense is measured using a Monte Carlo simulation model and recognized over the derived service period based on theexpected market performance as of the grant date.AdvertisingAdvertising costs are expensed as incurred. Advertising expenses were $0.5 million, $0.4 million and $0.3 million in fiscal years 2018, 2017 and2016, respectively.Income TaxesThe Company accounts for income taxes utilizing the liability method. Deferred income taxes are recorded to reflect consequences on future years ofdifferences between financial reporting and the tax basis of assets and liabilities measured using the enacted statutory tax rates and tax laws applicable to theperiods in which differences are expected to affect taxable earnings. A valuation allowance is recognized to the extent that it is more likely than not that thetax benefits will not be realized.The Company accounts for uncertainty in income taxes using a two-step approach to recognize and measure uncertain tax positions. The first step isto evaluate the tax position by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained onaudit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is morethan 50% likely of being realized upon settlement. The Company classifies the liability for unrecognized tax benefits as current to the extent that theCompany anticipates payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized in the provision forincome taxes. For additional discussion, see Note 15. Income Taxes.ConcentrationsThe Company may be subject to concentration of credit risk as a result of certain financial instruments consisting of accounts receivable and short-term investments. The Company performs ongoing credit evaluations of its customers and generally does not require collateral in exchange for credit.The following table sets forth major customers accounting for 10% or more of the Company’s net revenue: Year Ended June 30,2018 June 30,2017 June 30,2016 (As adjusted) (As adjusted) Tech Data Corporation 14% 16% 17% Jenne Corporation 13% 15% 14% Westcon Group Inc. 13% 12% 13%62EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) The following table sets forth major customers accounting for 10% or more of the Company’s accounts receivable balance: June 30,2018 June 30,2017 (As adjusted) Tech Data Corporation 17% 18% Jenne Corporation 13% 12% Westcon Group Inc. * 11%*Less than 10% of accounts receivableRecently Issued Accounting PronouncementsIn May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting which amends thescope of modification accounting for share-based payment arrangements and provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under Topic 718. Specifically, an entity would not applymodification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. Theguidance is effective prospectively for fiscal years beginning after December 15, 2017, and interim periods within that reporting period. Early adoption ispermitted, including adoption in any interim period. The adoption of this guidance will not have a material effect on the Company’s financial statements.This guidance will be effective for the Company beginning with its fiscal year 2019.In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments to provide guidance on the classificationof eight cash flow issues in order to reduce diversity in practice. The guidance is effective for fiscal years beginning after December 15, 2017, and interimperiods within that reporting period. The amendments in this update should be applied using a retrospective transition method to each period presented. Ifimpracticable to apply the amendments retrospectively for some of the issues, the amendments for those issues would be applied prospectively as of theearliest date practicable. The adoption of this guidance will not have a material effect on the Company’s presentation of cash flows. This guidance will beeffective for the Company beginning with its fiscal year 2019.In October 2016, the FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory, which requires the recognition of the incometax effects of intercompany sales and intra-entity transfers of assets, other than inventory, when the transfer occurs. ASU 2016-16 amends current U.S. GAAPthat prohibits recognition of current and deferred income taxes for all types of intra-entity asset transfers until the asset has been sold to a third party orotherwise recovered through use. The guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within that reportingperiod, and is applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the periodof adoption. The Company is currently evaluating the impact of the adoption of this standard will have on its consolidated financial statements. Thisguidance will be effective for the Company beginning with its fiscal year 2019.In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, which providesguidance for the recognition, measurement, presentation, and disclosure of financial assets and liabilities. This guidance will become effective for theCompany beginning with its fiscal year 2019. Upon adoption, the Company will be required to reclassify the gain related to its available-for-sale investmentsfrom accumulated other comprehensive loss to accumulated deficit as a cumulative-effect adjustment and begin recording future changes in fair valuethrough earnings. As of June 30, 2018, the Company had $0.5 million of unrealized holding gains, net of tax, related to its available-for-sale investmentsrecorded in accumulated other comprehensive loss in the accompanying consolidated balance sheet. Upon adoption of ASU 2016-01 on July 1, 2018, theCompany will record an adjustment to accumulated deficit of $0.5 million to eliminate the unrealized gains balance in accumulated other comprehensiveloss.In August 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-12, Derivatives and Hedging (Topic 815): TargetedImprovements to Accounting for Hedging Activities which is intended to allow companies to better align risk management activities and financial reportingfor hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation ofhedge results by expanding and refining hedge accounting for both nonfinancial and financial risk components and aligning the recognition andpresentation of the effects of the hedging instrument and the hedged item in the financial statements. The guidance is effective for fiscal years beginning afterDecember 15, 2018. The Company is evaluating the accounting, transition and disclosure requirements of the standard and cannot currently estimate thefinancial statement impact of adoption. This guidance is effective for the Company beginning with its fiscal year 2020.In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) which requires the identification of arrangements that should be accountedfor as leases by lessees. In general, for lease arrangements exceeding a twelve-month term, these arrangements must now be recognized as assets and liabilitieson the balance sheet of the lessee. Under Topic 842, a right-of-use asset and lease obligation will be recorded for all leases, whether operating or financing,while the statement of operations will reflect lease63EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) expense for operating leases and amortization/interest expense for financing leases. The balance sheet amount recorded for existing leases at the date ofadoption of Topic 842 must be calculated using the applicable incremental borrowing rate at the date of adoption. In addition, Topic 842 requires the use ofthe modified retrospective method, which will require adjustment to all comparative periods presented in the consolidated financial statements. TheCompany is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements and footnotedisclosures. The Company believes that Topic 842 will have a material impact on its financial position, as a result of recognizing right-of-use assets and leaseliabilities on its consolidated balance sheets. The Company is also evaluating the impact to the Company’s results of operations and does not believe therewill be a material impact to its consolidated statements of operations or consolidated cash flow statements upon adoption of Topic 842. This guidance will beadopted by the Company beginning with its fiscal year 2020.Recently Adopted Accounting PronouncementsIn May 2014, the FASB issued ASU No. 2014-09 (Topic 606) – Revenue from Contracts with Customers. Topic 606 supersedes the revenuerecognition requirements in the FASB ASC 605 – Revenue Recognition (Topic 605), and requires entities to recognize revenues when control of the promisedgoods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for thosegoods or services. The Company adopted Topic 606 as of July 1, 2017 using the full retrospective transition method. See Note 3 for further details.In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (ASU2017-04), which eliminates step two from the goodwill impairment test. Under the amendments in ASU 2017-04, an entity should recognize an impairmentcharge for the amount by which the carrying amount of a reporting unit exceeds its fair value; however, the loss recognized should not exceed the totalamount of goodwill allocated to that reporting unit. ASU 2017-04 is effective for annual and any interim impairment tests performed for periods beginningafter December 15, 2019 on a prospective basis, and earlier adoption is permitted for goodwill impairment tests performed on testing dates after January 1,2017. The Company’s early adoption of this accounting standard update in the fourth quarter of fiscal 2018 on a prospective basis did not have an impact onits consolidated financial statements. The adoption of this update simplified the Company’s annual goodwill impairment testing process by eliminating theneed to estimate the implied fair value of a reporting unit’s goodwill if its respective carrying value exceeds fair value. 3. RevenuesAdoption of ASC Topic 606 – Revenue from Contracts with CustomersIn May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). Under ASU 2014-09, revenue is recognized whena customer obtains control of promised goods or services and is recognized at an amount that reflects the consideration expected to be received in exchangefor such goods or services. In addition, ASU 2014-09 requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arisingfrom contracts with customers.The Company adopted Topic 606 on July 1, 2017, using the full retrospective method. This adoption primarily affected the Company’s accountingfor distributor and resellers revenues from a primarily “sell-through” model, where revenue is recognized upon the sale from the distribution channel to theend customer, to the “sell-in” method where revenue is recognized upon transfer of control to the Company’s customers. Under the sell-in method, theCompany is required to make estimates at the time of transfer of control to its distributors for variable consideration including estimated returns under stockrotation rights granted to stocking distributors and rebate claims. Additionally, the Company capitalizes contract acquisition costs such as commissions paidfor maintenance services contracts in excess of one year. Following the adoption of ASU 2014-09, the revenue recognition for the Company’s other salesarrangements remained materially consistent with its historical practice.Upon adoption of Topic 606, the Company applied certain permissible practical expedients that allows a) an entity to use the transaction price at thedate the contract was completed rather than estimating variable consideration amounts in the comparative reporting periods, b) that permits the omission ofprior-period information about its performance obligations, and c) that allows the Company to reflect the aggregate effect of all modifications that occurbefore the beginning of the earliest period presented when identifying the satisfied and unsatisfied performance obligations, determining the transactionprice and allocating the transaction price to the satisfied and unsatisfied performance obligations.Revenue RecognitionThe Company accounts for revenue in accordance with Topic 606, Revenue from Contracts with Customers, which the Company adopted on July 1,2017, using the full retrospective method. The Company derives the majority of its revenue from sales of its networking equipment, with the remainingrevenue generated from service fees relating to maintenance contracts, professional64EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) services, and training for its products. The Company sells its products and maintenance contracts direct to customers and to partners in two distributionchannels, or tiers. The first tier consists of a limited number of independent distributors that stock its products and sell primarily to resellers. The second tierof the distribution channel consists of a non-stocking distributors and value-added resellers that sell directly to end-users. Products and services may be soldseparately or in bundled packages. The Company considers customer purchase orders, which in some cases are governed by master sales agreements, to be the contracts with acustomer. For each contract, the Company considers the promise to transfer products and services, each of which are distinct, to be the identified performanceobligations. In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the netconsideration to which the Company expects to be entitled.For all of the Company’s sales and distribution channels, revenue is recognized when control of the product is transferred to the customer (i.e., whenthe Company’s performance obligation is satisfied), which typically occurs at shipment for product sales. Revenue from maintenance contracts is recognizedover time as the Company’s performance obligations are satisfied. This is typically the contractual service period, which ranges from one to three years. Forproduct sales to value-added resellers of the Company, non-stocking distributors and end-user customers, the Company generally does not grant returnprivileges, except for defective products during the warranty period, nor does the Company grant pricing credits. Sales taxes collected from customers areexcluded from revenues. Shipping costs are included in cost of product revenues. Sales incentives and other programs that the Company may make availableto these customers are considered to be a form of variable consideration and the Company maintains estimated accruals and allowances using the expectedvalue method. There were no material changes in the current period to the estimated transaction price for performance obligations which were satisfied orpartially satisfied during previous periods. Sales to stocking distributors are made under terms allowing certain price adjustments and limited rights of return (known as “stock rotation”) of theCompany’s products held in their inventory. Stock rotation rights grant the distributor the ability to return certain specified amounts of inventory. Stockrotation adjustments are an additional form of variable consideration and are estimated using the expected value method based on historical returnrates. Frequently, distributors need to sell at a price lower than the contractual distribution price in order to win business, and submit rebate requests for theCompany’s pre-approval prior to selling the product to a customer at the discounted price. At the time the distributor invoices its customer or soon thereafter,the distributor submits a rebate claim to the Company to adjust the distributor’s cost from the contractual price to the pre-approved lower price. After theCompany verifies that the claim was pre-approved, a credit memo is issued to the distributor for the rebate claim. In determining the transaction price, theCompany considers these rebate adjustments to be variable consideration. Such price adjustments are estimated using the expected value method based on ananalysis of actual claims, at the distributor level over a period of time considered adequate to account for current pricing and business trends. There were nomaterial changes in the current period to the estimated variable consideration for performance obligations which were satisfied or partially satisfied duringprevious periods. Performance Obligations. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit ofaccount in Topic 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, theperformance obligation is satisfied. Certain of the Company’s contracts have multiple performance obligations, as the promise to transfer individual goods orservices is separately identifiable from other promises in the contracts and, therefore, is distinct. For contracts with multiple performance obligations, theCompany allocates the contract’s transaction price to each performance obligation based on its relative standalone selling price. The stand-alone sellingprices are determined based on the prices at which the Company separately sells these products. For items that are not sold separately, the Companyestimates the stand-alone selling prices using the best estimated selling price approach. The Company’s performance obligations are satisfied at a point in time or over time as work progresses. Substantially all of the Company’s productrevenues as reflected on the consolidated statements of operations for the years ended June 30, 2018, 2017 and 2016 are recognized at a point in time.Substantially all of the Company’s service revenue is recognized over time. For revenue recognized over time, the Company uses an input measure, dayselapsed, to measure satisfaction of the performance obligation. At June 30, 2018, the Company had $174.5 million of remaining performance obligations, which is comprised of deferred maintenance revenue andservices not yet delivered. The Company expects to recognize approximately 75 percent of its remaining performance obligations as revenue in fiscal 2019,an additional 15 percent by fiscal 2020 and 10 percent of the balance thereafter.Contract Balances. The timing of revenue recognition, billings and cash collections results in billed accounts receivable and deferred revenue in theconsolidated balance sheets. Services provided under renewable support arrangements of the Company are billed in accordance with agreed-upon contractualterms, which are typically at periodic intervals (e.g., quarterly or annually). The Company sometimes receives payments from its customers in advance ofservices being provided, resulting in deferred revenues. These liabilities are reported on the consolidated balance sheets on a contract-by-contract basis atthe end of each reporting period.65EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Revenue recognized for the years ended June 30, 2018 and 2017, that was included in the deferred revenue balance at the beginning of each periodwas $76.6 million and $70.5 million, respectively.Contract Costs. The Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of theassets that the Company otherwise would have recognized is one year or less. Management expects that commission fees paid to sales representative as aresult of obtaining service contracts and contract renewals, in excess of one year, are recoverable and therefore the Company capitalized them as contractcosts in the amount of $4.3 million and $2.5 million at June 30, 2018 and 2017, respectively, in “Other assets” in the accompanying consolidated balancesheets. Capitalized commission fees are amortized on a straight-line basis over the average period of service contracts of approximately three years, and areincluded in “Sales and marketing” in the accompanying consolidated statements of operations. Amortization recognized during the years ended June 30,2018, 2017 and 2016 was $2.1 million, $1.5 million and $0.9 million, respectively.Revenue by Category: The following tables set forth the Company’s revenue disaggregated by sales channel and geographic region based on thebilling addresses of its customers (in thousands): Year Ended June 30, 2018 Net Revenues Distributor Direct Total Americas: United States $271,975 $219,642 $491,617 Other 19,414 25,274 44,688 Total Americas 291,389 244,916 536,305 EMEA: 218,682 136,064 354,746 APAC: 15,621 76,470 92,091 Total net revenues $525,692 $457,450 $983,142 Year Ended June 30, 2017 (As adjusted) Net Revenues Distributor Direct Total Americas: United States $146,805 $161,175 $307,980 Other 11,861 13,022 24,883 Total Americas 158,666 174,197 332,863 EMEA: 135,414 84,658 220,072 APAC: 8,953 45,196 54,149 Total net revenues $303,033 $304,051 $607,084 Year Ended June 30, 2016 (As adjusted) Net Revenues Distributor Direct Total Americas: United States $113,715 $120,313 $234,028 Other 21,246 22,479 43,725 Total Americas 134,961 142,792 277,753 EMEA: 106,853 86,064 192,917 APAC: 7,251 41,913 49,164 Total net revenues $249,065 $270,769 $519,83466EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Adjustments to Previously Reported Financial Statements from the Adoption of Accounting PronouncementsThe following table presents the effect of the adoption of ASU 2014-09 on the Company’s consolidated balance sheet as of June 30, 2017, (inthousands): As of June 30, 2017 As Reported Adjustment As Adjusted Accounts receivable, net$120,770 $(27,655) $93,115 Inventories 45,880 1,530 47,410 Total current assets 324,967 (26,125) 298,842 Other assets 22,586 2,479 25,065 Total assets$483,346 $(23,646) $459,700 Accrued warranty$10,007 $577 $10,584 Other accrued liabilities 36,713 331 37,044 Deferred distributors revenue, net of cost of sales to distributors 43,525 (43,525) — Total current liabilities 255,822 (42,617) 213,205 Accumulated deficit (800,257) 18,971 (781,286)Total stockholders’ equity 106,707 18,971 125,678 Total liabilities and stockholders’ equity$483,346 $(23,646) $459,700The following tables present the effect of the adoption of ASU 2014-09 on the Company’s consolidated statements of operations for the years endedJune 30, 2017 and 2016 (in thousands, except per share amounts): Year Ended June 30, 2017 As Reported Adjustment As Adjusted Net revenues Product$451,459 $8,966 $460,425 Service 146,659 — 146,659 Total net revenues 598,118 8,966 607,084 Cost of revenues Product 217,727 2,494 220,221 Service 55,906 — 55,906 Total cost of revenues 273,633 2,494 276,127 Gross profit Product 233,732 6,472 240,204 Service 90,753 — 90,753 Total Gross profit 324,485 6,472 330,957 Sales and marketing expenses 167,927 (301) 162,626 Operating loss (733) 6,773 6,040 Net income (loss) before tax (4,177) 6,773 2,596 Net income (loss)$(8,517) $6,773 $(1,744) Basic and diluted net loss per share Net loss per share -

Business CombinationsThe Company completed three acquisitions during the year ended June 30, 2018 and an acquisition during the year ended June 30, 2017. Theacquisitions have been accounted for using the acquisition method of accounting. The purchase price has been allocated to tangible and identifiableintangible assets acquired and liabilities assumed. The fair value of working capital related items, such as other current assets and accrued liabilities,approximated their book values at the date of acquisition. Inventories were valued at fair value using the net realizable value approach. The fair value ofproperty and equipment was determined using a cost approach. The fair value of the acquired deferred revenue was estimated using the cost build-upapproach. The cost build-up approach determines fair value using estimates of the costs required to provide the contracted deliverables plus an assumedprofit. The total costs including the assumed profit were adjusted to present value using a discount rate considered appropriate. The resulting fair valueapproximates the amount that the Company would be required to pay to a third party to assume the obligation. Valuations of the intangible assets werevalued using income approaches based on management projections, which the Company considers to be Level 3 inputs. The Company also continues toanalyze the tax implications of the acquisition of the intangible assets which may ultimately impact the overall level of goodwill associated with theacquisition. Results of operations of the acquired entities are included in the Company’s operations beginning with the closing date of each acquisition.Fiscal 2018 AcquisitionsData Center BusinessThe Company completed its acquisition of the data center business (the “Data Center Business”) of Brocade Communication Systems, Inc.(“Brocade”) on October 27, 2017 (the “Data Center Business Closing Date”), pursuant to an Asset Purchase Agreement (the “Data Center Business APA”)dated as of October 3, 2017, by and between the Company and Brocade. Under the terms and conditions of the Data Center Business APA, the Companyacquired customers, employees, technology and other assets of the Data Center Business as well as assumed certain contracts and other liabilities of the DataCenter Business.The fair value of consideration transferred on the Data Center Business Closing Date includes: •cash payment upon closing of $23.0 million, •deferred payments of $1.0 million per quarter for the next twenty full fiscal quarters of the Company following the acquisition date discountedto their present value, •contingent consideration in the form of quarterly earnout payments equal to 50% of the profits of the Data Center Business for the five-yearperiod commencing at the end of the first full fiscal quarter of the Company following the acquisition of the Data Center Business discountedto their present value, •an amount payable due to the excess working capital acquired over the target working capital agreed upon in the Data Center Business APA,and, •a portion of the fair value of stock awards granted to employees assumed from Brocade for which their services were provided prior to the DataCenter Business Closing Date.The components of aggregate estimated purchase consideration are as follows (in thousands):69EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Estimated purchase considerationOctober 27,2017 Cash paid to sellers at closing$23,000 Deferred payments 18,430 Contingent consideration 34,100 Working capital adjustment 6,534 Replacement of stock-based awards 2,273 Aggregate estimated purchase consideration$84,337The purchase price allocation as of the Data Center Business Closing Date is set forth in the table below and reflects fair values.

The goodwill recognized is attributable primarily toexpected synergies and the assembled workforce of the Data Center Business. The Company anticipates both the goodwill and intangible assets to be fullydeductible for income tax purposes.Pursuant to negotiations regarding various contractual arrangements with Broadcom, in August 2018, the Company resolved its contingentconsideration obligation related to the Data Center Business acquisition. The outstanding balance was revalued to its final fair value as of June 30, 2018resulting in a charge of $1.5 million which is included in “General and administrative” expense in the accompanying consolidated statements of operations.The results of operations of the Data Center Business are included with those of the Company beginning October 28, 2017. The Data Center Businessrevenue for the year ended June 30, 2018 was $136.3 million and has been incorporated into the revenue of the Company. The associated expenses of theData Center Business have been incorporated with the results of operations of the Company as a product line and, therefore, stand-alone operating results arenot available. During the year ended June 30, 2018, the Company incurred acquisition and integration related expenses of $40.2 million associated with theacquisition of the Data Center Business, including a $25.0 million consent fee paid to terminate a previous asset purchase agreement entered into by theCompany to purchase the Data Center Business from Broadcom Corporation, in anticipation of Broadcom’s proposed acquisition of Brocade. The fee was70EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) paid to allow the Company to buy the Data Center Business directly from Brocade. Such acquisition-related costs are included in “Acquisition andintegration costs, net of bargain purchase gain” in the accompanying consolidated statements of operations. The costs, which the Company expensed asincurred, consist primarily of professional fees to financial and legal advisors and IT consultants.Campus Fabric BusinessThe Company completed its acquisition of Avaya Inc.’s. (“Avaya”) fabric-based secure networking solutions and network security solutions business(the “Campus Fabric Business”) on July 14, 2017, (the “Campus Fabric Business Closing Date”) pursuant to an Asset Purchase Agreement (the “CampusFabric Business APA”) dated March 7, 2017. Under the terms and conditions of the Campus Fabric Business APA, the Company acquired the customers,employees, technology and other assets of the Campus Fabric Business, as well as assumed certain contracts and other liabilities of the Campus FabricBusiness, for total consideration of $79.4 million, calculated as $100.0 million, less adjustments set forth in the Campus Fabric Business APA related to networking capital, deferred revenue, certain assumed lease obligations and certain assumed pension obligations for transferred employees of the Campus FabricBusiness.The acquisition has been accounted for using the acquisition method of accounting.

The goodwill recognized is attributable primarily toexpected synergies and the assembled workforce of the Campus Fabric Business. The Company anticipates both the goodwill and intangible assets to befully deductible for income tax purposes. The Company also acquired an indefinite lived asset of $2.4 million which represents the fair value of in-process research and development activities.During the three months ended March 31, 2018, the related research and development efforts were completed and the Company reclassified the in-processresearch and development of $2.4 million to developed technology and began recognizing amortization expense over its estimated useful life.The results of operations of the Campus Fabric Business are included in the accompanying consolidated results of operations beginning July 14,2017. The Campus Fabric Business revenue for the year ended June 30, 2018 was $179.8 million and has been incorporated into the revenue of theCompany. The associated expenses of the Campus Fabric Business have been incorporated with the results of operations of the Company as a product lineand, therefore, stand-alone operating results are not available. In the year ended June 30, 2018, the Company incurred acquisition and integration relatedexpenses of $18.7 million associated with the acquisition of the Campus Fabric Business.

Fair Value MeasurementsA three-tier fair value hierarchy is utilized to prioritize the inputs used in measuring fair value. The hierarchy gives the highest priority to quotedprices in active markets (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels are defined as follows: •Level 1 Inputs - unadjusted quoted prices in active markets for identical assets or liabilities; •Level 2 Inputs - quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, eitherdirectly or indirectly through market corroboration, for substantially the full term of the financial instrument; and •Level 3 Inputs - unobservable inputs reflecting the Company’s own assumptions in measuring the asset or liability at fair value.The following table presents the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value on a recurring basis (inthousands):June 30, 2018 Level 1 Level 2 Level 3 Total Assets Investments: Marketable securities $1,459 $— $— $1,459 Total assets measured at fair value $1,459 $— $— $1,459 Liabilities Acquisition-related contingent consideration obligations $— $— $12,749 $— Total liabilities measured at fair value $— $— $12,749 $—76EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) June 30, 2017 Level 1 Level 2 Level 3 Total Assets Investments: Money market funds $4,291 $— $— $4,291 Investment in non-marketable equity — — 3,000 3,000 Total assets measured at fair value $4,291 $— $3,000 $7,291 Level 1 investments: The Company holds investments in equity securities acquired from the sale of an investment in non-marketable equity securities during the firstquarter of fiscal 2018, which is classified as available-for-sale marketable securities at Level 1 as the investments have readily determinable fair value (seebelow, Level 3 investments). An unrealized holding gain on the investments was $0.5 million as of June 30, 2018 which will be reclassified fromaccumulated other comprehensive loss to accumulated deficit on July 1, 2018 upon an adoption of ASU 2016-01 (see Note 2).Level 2 investments: The Company includes U.S. government and sovereign obligations, most government agency securities, investment-grade corporate bonds, and state,municipal and provincial obligations for which quoted prices are available as Level 2. There were no transfers of assets or liabilities between Level 1 andLevel 2 for the periods presented.The fair value of the borrowings under the Credit Agreement is estimated based on valuations provided by alternative pricing sources supported byobservable inputs which is considered Level 2. Due to the short duration until maturity of the Credit Agreement, the fair value approximates the face amountof the Company’s indebtedness of $200.0 million and $93.7 million as of June 30, 2018 and 2017, respectively. Such differences are immaterial for allperiods presented.Level 3 investments: Certain of the Company’s assets, including intangible assets and goodwill are measured at fair value on a non-recurring basis if impairment isindicated. As of June 30, 2017, the Company reflected its non-marketable equity investment as Level 3 in the fair value hierarchy as it is based on unobservableinputs that market participants would use in pricing this asset due to the absence of recent comparable market transactions and inherent lack ofliquidity. During fiscal 2015, the Company purchased a $3.0 million equity interest in a company that operated in the enterprise software platformindustry. The Company did not enter into any other transactions with the investee during fiscal 2017 or the first quarter of fiscal 2018. During the threemonths ended September 30, 2017, the investee was acquired by a third party. The Company received $6.8 million as consideration for its equity interest inthe investee, including $5.4 million in cash and 65,937 shares of the third party’s publicly-traded common stock (the “Acquirer’s common stock”) with amarket value of $1.4 million. During the first quarter of fiscal 2018, the Company received $5.8 million of the consideration, consisting of $4.9 million incash and 41,685 shares with a market value of $0.9 million. The remainder of the consideration consisting of $0.5 million of cash and $0.5 million of 23,252shares of the Acquirers common stock will remain in escrow for a period of 18 months from the date of sales for general representations and warranties. A gainof $3.8 million related to this sale was recorded in “Other income (expense), net” in the accompanying consolidated statement of operations for the yearended June 30, 2018.During the fourth quarter of fiscal 2018, the Company sold 18,700 shares of the Acquirer’s common stock and recorded a gain of $0.2 million. Theremaining 22,985 shares held by the Company and 23,252 shares to be released from escrow within one year are considered Level 1 investments as thesehave a readily determinable fair value and quoted prices in active markets.During the year ended June 30, 2018, the Company recorded a liability for contingent consideration related to its acquisition of the CF Business (seeNote 4 for additional information related to the acquisition). The fair value measurement of the contingent consideration obligations is determined usingLevel 3 inputs. The fair value of contingent consideration obligations is based on a discounted cash flow model. These fair value measurements representLevel 3 measurements as they are based on significant inputs not observable in the market. Significant judgment is employed in determining theappropriateness of these assumptions as of the acquisition date and for each subsequent period. Accordingly, changes in assumptions could have a materialimpact on the amount of contingent consideration expense the Company records in any given period. Changes in the value of the contingent considerationobligations would be recorded in general and administrative expenses in the accompanying consolidated statements of operations.The change in the acquisition-related contingent consideration obligations is as follows (in thousands):77EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Year Ended June 30, 2018 Beginning balance $— Initial fair value measurements 47,030 Payments (671)Resolution of contingency (36,980)Accretion on discount 3,134 Change in fair value 236 Ending balance $12,749There were no transfers of assets or liabilities between Level 2 and Level 3 during the year ended June 30, 2018 or 2017.

The lease incentives payments are deferredand amortized on a straight-line basis over the term of the lease as an offset to rent expense.Future annual minimum lease payments under all non-cancelable operating leases having initial or remaining lease terms in excess of one year atJune 30, 2018, were as follows (in thousands):For the fiscal year ending: Future LeasePayments 2019 $27,517 2020 18,014 2021 17,560 2022 16,632 2023 14,157 Thereafter 18,983 Total minimum payments $112,863 Rent expense was $12.9 million, $9.4 million and $8.5 million in fiscal years 2018, 2017 and 2016, respectively.Purchase CommitmentsThe Company currently has arrangements with contract manufacturers and suppliers for the manufacture of its products. The arrangements allow themto procure long lead-time component inventory based upon a rolling production forecast provided by the Company. The Company is obligated to thepurchase of long lead-time component inventory that its contract manufacturer procures in accordance with the forecast, unless the Company gives notice oforder cancellation outside of applicable component lead-times. As of June 30, 2018, the Company had non-cancelable commitments to purchase $144.0million of such inventory, which will be received and consumed during the first half of fiscal 2019. The Company expects to utilize its non-cancelablepurchase commitments in the normal ongoing operations.Legal ProceedingsThe Company may from time to time be party to litigation arising in the course of its business, including, without limitation, allegations relating tocommercial transactions, business relationships or intellectual property rights. Such claims, even if not meritorious, could result in the expenditure ofsignificant financial and managerial resources. Litigation in general, and intellectual property and securities litigation in particular, can be expensive anddisruptive to normal business operations. Moreover, the results of legal proceedings are difficult to predict.In accordance with applicable accounting guidance, the Company records accruals for certain of its outstanding legal proceedings, investigations orclaims when it is probable that a liability will be incurred and the amount of loss can be reasonably estimated. The Company evaluates, at least on a quarterlybasis, developments in legal proceedings, investigations or claims that could affect the amount of any accrual, as well as any developments that would resultin a loss contingency to become both probable and reasonably estimable. When a loss contingency is not both probable and reasonably estimable, theCompany does not record a loss accrual. However, if the loss (or an additional loss in excess of any prior accrual) is at least a reasonable possibility andmaterial, then the Company would disclose an estimate of the possible loss or range of loss, if such estimate can be made, or disclose that an estimate cannotbe made. The assessment whether a loss is probable or a reasonable possibility, and whether the loss or a range of loss is estimable, involves a series ofcomplex judgments about future events. Even if a loss is reasonably possible, the Company may not be able to estimate a range of possible loss, particularlywhere (i) the damages sought are substantial or indeterminate, (ii) the proceedings are in the early stages, or (iii) the matters involve novel or unsettled legaltheories or a large number of parties. In such cases, there is considerable uncertainty regarding the ultimate resolution of such matters, including the amountof any possible loss, fine or penalty. Accordingly, for current proceedings, except as noted below, the Company is currently unable to estimate anyreasonably possible loss or range of possible loss. However, an adverse resolution of one or more of such matters could have a material adverse effect on theCompany's results of operations in a particular quarter or fiscal year.81EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Brazilian Tax Assessment MattersOn May 28, 2007, the Public Treasury Department of the State of Sao Paolo, Brazil (the “Tax Authority”) assessed the Company’s Braziliansubsidiary, Enterasys Networks do Brasil Ltda. (“Enterasys Brasil”), based on an alleged underpayment of taxes. The Tax Authority also charged interest andpenalties with respect to the assessment (collectively, the “ICMS Tax Assessment”). The Tax Authority denied Enterasys Brasil the use of certain presumedtax credits granted by the State of Espirito Santo, Brazil under the terms of the FUNDAP program for the period from February 2003 to December 2004. Thevalue of the disallowed presumed tax credits is BRL 3.4 million (US $1.0 million), excluding interest and penalties. All currency conversions in this LegalProceedings section are as of June 30, 2018.Unable to resolve the matter at the administrative level, on October 1, 2014, Enterasys Brasil filed a lawsuit in the 11th Public Treasury Court of theSao Paolo State Court of Justice (Judiciary District of Sao Paolo) to overturn or reduce the ICMS Tax Assessment. As part of this lawsuit, Enterasys Brasilrequested a stay of execution, so that no tax foreclosure could be filed and no guarantee would be required until the court issued its final ruling. On or aboutOctober 6, 2014, the court granted a preliminary injunction staying any execution on the assessment, but requiring that Enterasys Brasil deposit the assessedamount with the court. Enterasys Brasil appealed this ruling and, on or about January 28, 2015, the appellate court ruled that no cash deposit (or guarantee)was required. In a decision dated August 28, 2017, and published on October 3, 2017, the court validated the assessment and penalty imposed by the TaxAuthority, but ruled that the Tax Authority was charging an unlawfully high interest rate on the tax assessment and penalty amounts, and ordered the interestrate reduced to the maximum Federal rate. The August 28, 2017 decision, were it to become final, would require Enterasys Brasil to pay a total of BRL 16.9million (approximately U.S. $5.1 million), which includes penalties, court costs, attorneys’ fees, and accrued interest as of June 30, 2018. The Companybelieves the ICMS Tax Assessment against Enterasys Brasil is without merit, and has appealed the lower court’s decision. The appellate court ruled that nocash deposit (or guarantee) is required during the pendency of the appeal.Based on the currently available information, the Company believes the ultimate outcome of the ICMS Tax Assessment litigation will not have amaterial adverse effect on the Company's financial position or overall results of operations. However, due to the complexities and uncertainty surroundingthe judicial process in Brazil and the nature of the claims asserted, there can be no assurance of a favorable outcome for Enterasys Brasil, which recorded anaccrual of BRL 9.4 million (approximately U.S. $2.9 million) as of the date the Company acquired Enterasys Networks.The Company made a demand on April 11, 2014 for a defense from, and indemnification by, the former equity holder of Enterasys Networks, Inc.(“Seller”) in connection with the ICMS Tax Assessment. Seller agreed to assume the defense of the ICMS Tax Assessment on May 20, 2014. In addition,through the settlement of an indemnification-related lawsuit with the Seller on June 18, 2015, Seller agreed to continue to defend the Company with respectto the ICMS Tax Assessment and to indemnify the Company for losses related thereto subject to certain conditions. These conditions include the offsetting offoreign income tax benefits realized by the Company in connection with the acquisition of Enterasys. Based upon current projections of the foreign incometax benefits to be realized, and the potential liability in the event of an adverse final judgment in the ICMS Tax Assessment litigation, the Company does notpresently anticipate that any amounts under the indemnification will be due from the Seller in connection with the ICMS Tax Assessment.In re Extreme Networks, Inc. Securities LitigationOn October 23 and 29, 2015, punitive class action complaints alleging violations of securities laws were filed in the U.S. District Court for theNorthern District of California against the Company and three of its former officers (Charles W. Berger, Kenneth B. Arola, and John T.Kurtzweil). Subsequently, the cases were consolidated (In re Extreme Networks, Inc. Securities Litigation, No. 3:15-CY-04883-BLF). Plaintiffs allege thatdefendants violated the securities laws by disseminating materially false and misleading statements and concealing material adverse facts regarding theCompany’s financial condition, business operations and growth prospects. Plaintiffs seek unspecified damages on behalf of a purported class of investorswho purchased the Company’s common stock from September 12, 2013 through April 9, 2015. On June 28, 2016, the Court appointed a lead plaintiff. OnSeptember 26, 2016, the lead plaintiff filed a consolidated complaint. On November 10, 2016, defendants filed a motion to dismiss, which the Court grantedwith leave to amend on April 27, 2017. On June 2, 2017, the lead plaintiff filed an amended complaint, which, on July 10, 2017, defendants again moved todismiss. In a March 21, 2018 Order (the “March 2018 Order”), the Court granted in part and denied in part the defendants’ motion. The March 2018 Ordernarrowed the scope of the case, but allowed certain claims to proceed. On July 18, 2018, the parties to the litigation commenced a mediation process with theassistance of a professional mediator and the Company believes the parties have arrived at an agreement in principle which they are in the process ofdocumenting and which is subject to court approval. On February 18, 2016, a shareholder derivative case was filed in the Superior Court of California, Santa Clara County (Shaffer v. Kispert et al., No. 16CV 291726). The complaint names current and former officers and directors as defendants, and seeks recovery on behalf of the Company based onsubstantially the same allegations as the securities class action litigation described above. 82EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) As a result of the March 2018 Order, the stipulated stay of the derivative litigation ended. On July 18, 2018, the parties to the litigation commenced amediation process with the assistance of a professional mediator and the Company believes the parties have arrived at an agreement in principle which theyare in the process of documenting and which is subject to court approval. XR Communications, LLC d/b/a Vivato Technologies v. Extreme Networks, Inc. Patent Infringement Suit On April 19, 2017, XR Communications, LLC (“XR”) (d/b/a Vivato Technologies) filed a patent infringement lawsuit against the Company in theCentral District of California (XR Communications, LLC, dba Vivato Technologies v. Extreme Networks, Inc., No. 2:17-cv-2953-AG). The operative SecondAmended Complaint asserts infringement of U.S. Patent Nos. 7,062,296, 7,729,728, and 6,611,231 based on the Company’s manufacture, use, sale, offer forsale, and/or importation into the United States of certain access points and routers supporting multi-user, multiple-input, multiple-output technology. XRseeks unspecified damages, on-going royalties, pre- and post-judgment interest, and attorneys’ fees (but no injunction). On July 24, 2017, the Company filedits answer. In orders dated April 10 and May 22, 2018, the Court stayed the case pending a resolution by the Patent Trial and Appeal Board of inter partesreview petitions filed by several defendants in other XR-related patent lawsuits challenging the validity of the asserted patents. Given the stay, the Courttook off calendar all previously scheduled events (including a Markman hearing and potential trial date), and scheduled a status conference on October 22,2018. The Company believes the claims are without merit, and intends to defend them vigorously.DIFF Scale Operation Research, LLC v. Extreme Networks, Inc.On March 15, 2018, DIFF Scale Operation Research, LLC (“DIFF”) filed a patent infringement lawsuit against the Company in the United StatesDistrict Court for the Southern District of New York (DIFF Scale Operation Research, LLC v. Extreme Networks, Inc., No. 18-cv-2324-KBF). The complaintalleged infringement of seven patents (four expired) generally directed to virtual connection networking. The parties have settled this dispute, and the courtsigned a stipulation and order of dismissal with prejudice on June 21, 2018.Be Labs, Inc. v. Extreme Networks, Inc.On April 25, 2018, Be Labs, Inc. (“Be Labs”) filed a patent infringement lawsuit against the Company in the United States District Court for theDistrict of Delaware (Be Labs, Inc. v. Extreme Networks, Inc., No. 1:18-cv-00626). The complaint alleged direct and indirect infringement of two patentsgenerally directed to a multimedia wireless distribution system for home or office use, and appears to accuse the Company’s 802.11ac- and 802.11n-compliant ExtremeWireless products. The parties have settled this dispute, and Be Labs dismissed the case with prejudice on July 9, 2018.Orckit IP, LLC v. Extreme Networks, Inc., Extreme Networks Ireland Ltd., and Extreme Networks GmbHOn February 1, 2018, Orckit IP, LLC (“Orckit”) filed a patent infringement lawsuit against the Company and its Irish and German subsidiaries in theDistrict Court in Dusseldorf, Germany. The lawsuit alleges direct and indirect infringement of the German portion of European Patent EP 1 958 364 B1 basedon the offer, distribution, use, possession and/or importation into Germany of certain network switches equipped with the ExtremeXOS operatingsystem. Orckit is seeking injunctive relief, an accounting, and an unspecified declaration of liability for damages and costs of the lawsuit. On May 3, 2018,Extreme Networks GmbH filed a separate nullity action in the Federal Patent Court in Munich, seeking to invalidate the asserted patents, and on May 4,2018, the defendants answered the complaint, denying any infringement and seeking a stay of the action pending the conclusion of the nullity action. TheCompany believes the claims are without merit, and intends to defend them vigorously.Indemnification ObligationsSubject to certain limitations, the Company may be obligated to indemnify its current and former directors, officers and employees. These obligationsarise under the terms of its certificate of incorporation, its bylaws, applicable contracts, and applicable law. The obligation to indemnify, where applicable,generally means that the Company is required to pay or reimburse, and in certain circumstances the Company has paid or reimbursed, the individuals'reasonable legal expenses and possibly damages and other liabilities incurred in connection with certain legal matters. For example, the Company currentlyis paying or reimbursing legal expenses being incurred by certain current and former officers and directors in connection with the shareholder litigationdescribed above. The Company also procures Directors and Officers insurance to help cover its defense and/or indemnification costs, although its ability torecover such costs through insurance is uncertain. While it is not possible to estimate the maximum potential amount that could be owed under theseindemnification agreements due to the Company’s limited history with prior indemnification claims, indemnification (including defense) costs could, in thefuture, have a material adverse effect on the Company’s consolidated financial position, results of operations and cash flows. As of June 30, 2018, theCompany has the outstanding indemnification claims described above.83EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) 10. Stockholders’ EquityPreferred StockIn April 2001, in connection with the entering into of the Company’s Rights Agreement, the Company authorized the issuance of preferred stock. Thepreferred stock may be issued from time to time in one or more series. The Board of Directors is authorized to provide for the rights, preferences and privilegesof the shares of each series and any qualifications, limitations or restrictions on these shares. As of June 30, 2018, no shares of preferred stock wereoutstanding.Stockholders’ Rights AgreementOn April 26, 2012, the Company entered into an Amended and Restated Rights Agreement between the Company and Computershare ShareholderServices LLC as the rights agent (the “Restated Rights Plan”). The Restated Rights Plan governs the terms of each right (“Right”) that has been issued withrespect to each share of Common Stock of Extreme Networks. Each Right initially represents the right to purchase one one-thousandth of a share of theCompany’s Preferred Stock. The Restated Rights Plan replaces in its entirety the Rights Agreement, dated as of April 27, 2001, as subsequently amended,between the Company and Mellon Investor Services LLC (the “Prior Rights Plan”).The Board adopted the Restated Rights Plan to preserve the value of deferred tax assets, including net operating loss carry forwards of the Company,with respect to its ability to fully use its tax benefits to offset future income which may be limited if the Company experiences an “ownership change” forpurposes of Section 382 of the Internal Revenue Code of 1986 as a result of ordinary buying and selling of its common stock. Following its review of theterms of the plan, the Board decided it was necessary and in the best interests of the Company and its stockholders to enter into the Restated Rights Plan. TheRestated Rights Plan incorporates the Prior Rights Plan and the amendments thereto into a single agreement and extended the term of the Prior Rights Plan toApril 30, 2013. Each year since 2013 the Board and shareholders have approved an amendment providing for a one-year extension of the term of theRestated Rights Plan. Our Board of Directors unanimously approved an amendment to the Restated Rights Plan on May 9, 2018 to extend the RestatedRights Plan through May 31, 2019, subject to ratification by a majority of the stockholders of the Company at the next annual shareholders meeting,expected to be held on November 8, 2018.11.

In addition, up to 12.7 million shares subject to stock options and awards available for issuance under the2005 Plan may be transferred to the 2013 Stock Plan and would be added to the number of shares available for future grant under the 2013 Plan. The 2013Plan includes provisions upon the granting of certain awards defined by the 2013 Plan as Full Value Awards in which the shares available for grant under the2013 Plan are decremented 1.5 shares for each such award granted. Upon forfeiture or cancellation of unvested awards, the same ratio is applied in returningshares to the 2013 Plan for future issuance as was applied upon granting. During the fiscal years ended June 30, 2018 and 2017, an additional 9.0 millionshares and 8.3 million shares, respectively, were authorized and made available for grant under the 2013 Plan. As of June 30, 2018, total options and awardsto acquire 9.0 million shares were outstanding under the 2013 Plan and 12.1 million shares are available for grant under the 2013 Plan.

The Company recognizes compensation expense on the awards over thevesting period based on the award’s intrinsic value as of the date of grant.85EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) The following table summarizes stock award activity (shares and market value in thousands): Number of Shares Weighted- AverageGrantDate Fair Value Aggregate FairMarket Value Non-vested stock awards outstanding at June 30, 2017 6,664 $4.66 Granted 4,595 $11.15 Vested (2,956) $3.79 Cancelled (539) $8.05 Non-vested stock awards outstanding at June 30, 2018 7,764 $8.60 $61,804The aggregate fair value, as of the respective vesting dates of RSUs vested during the fiscal years ended June 30, 2018, 2017 and 2016 was $51.2million, $9.1 million and $8.6 million, respectively.Fiscal 2018 PSUDuring fiscal 2018, the Company approved the grant of 1.2 million stock awards to its vice president level employees or above (“VPs”), including 0.6million stock awards to its Executive Officers. Fifty percent (50%) of the stock awards granted to the VPs, except the chief executive officer, were in the formof PSUs and fifty percent (50%) of the stock awards granted were in the form of service-based RSUs. The Company’s chief executive officer received sixtypercent (60%) of his stock award grant in the form of PSUs, while forty percent (40%) of this award were in the form of RSUs. The RSUs vest from the originalgrant date as to one-third (1/3) on the one-year anniversary and one-twelfth (1/12) each quarter thereafter, subject to continued service to the Company.The PSUs referenced in the preceding paragraph will be considered earned once the Company’s U.S. GAAP earnings aggregates at least $0.32 per shareover two consecutive quarters (the “2018 Performance Threshold”). Upon satisfying the 2018 Performance Threshold, the PSUs will vest with respect to thesame number of RSUs that have vested which were granted on the same date and thereafter, will vest on the same schedule as the RSUs, subject to continuedservice to the Company. If the 2018 Performance Threshold is not met by the third anniversary of the grant date, the award is canceled. In addition, the 2018Performance Threshold will be deemed satisfied upon the closing of a Change in Control (within the meaning of the Company’s 2013 Equity Incentive Plan)in the event the per share consideration received by the Company’s stockholders equals or exceeds $16.00 per share; or, in the event the consideration is lessthan $16.00 per share, the number of PSUs deemed to be earned will be determined by multiplying the number of PSUs by the ratio of the aggregate earningsper share of the last two quarters prior to the Change of Control to the $0.32 Performance Threshold. The grant date fair value per share of the PSUs referencedabove was $10.90. During the year ended June 30, 2018, none of the PSU grants referenced above achieved their 2018 Performance Threshold.During fiscal 2018, the Company approved the grant of 0.1 million stock awards with market-based vesting criteria to certain VPs with grant date fairvalues per share ranging from $10.61 to $12.19 determined by using the Monte-Carlo simulation model.Fiscal 2017 PSUDuring fiscal 2017, the Company approved the grant of 1.5 million stock awards to its VPs, including 0.7 million stock awards to its ExecutiveOfficers. Fifty percent (50%) of the stock awards granted to the VPs were in the form of PSUs and fifty percent (50%) of the stock awards granted were in theform of RSUs. The RSUs vest from the original grant date as to one-third (1/3) on the one-year anniversary and one-twelfth (1/12) each quarter thereafter,subject to continued service to the Company. The PSUs referenced in the preceding paragraph were considered earned once the Company’s stock price equaled or exceeded $5.00 per share for 30consecutive trading days after January 1, 2017 (the “2017 Performance Threshold”). The grant date fair values per share of the PSUs were determined byusing the Monte-Carlo simulation model, ranging $3.02 to $3.09. The assumptions used in the Monte-Carlo simulation includes the expected volatility of56%, risk-free rate of 0.9%, no expected divided yield, expected term of 3.0 years and possible future stock prices over the performance period based onhistorical stock and market prices. The assumptions used in the Monte-Carlo simulation includes the risk-free rate, expected divided yield, expected term,and possible future stock prices over the performance period based on historical stock and market prices. Once the 2017 Performance Threshold goal wasattainted, the PSUs began to vest on the same schedule as the RSUs that were granted at the same time, subject to continued service to the Company. Duringthe year ended June 30, 2017, all of the PSUs referenced above achieved their 2017 Performance Threshold and as such, began vesting and will be releasedon the schedule as noted, subject to continued service to the Company.During fiscal 2017, the Company approved grants of 1.4 million stock awards in the form of PSUs to certain VPs, including 0.9 million shares to itsExecutive Officers. Fifty percent (50%) of the PSUs are earned based on the Company’s stock price appreciation (the “Stock Price PSUs”) and fifty percent(50%) of the PSUs are earned based on the Company’s total stockholder return relative to the S&P Small Cap 600 Capped Information Technology Index (the“TSR PSUs”).86EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) The Stock Price PSUs represent the right to receive a number of shares of common stock up to one and one-third of the target number of Stock PricePSUs.

They are earned andvest as follows based on the positive percentage point difference between the Company’s total stockholder return and the total stockholder return for the S&PSmall Cap 600 Capped Information Technology Index over the performance period from May 4, 2017 to May 4, 2020, subject to the grantees’ continuedservice through the certification of performance:Level Percentage point differencebetween Company TSR andindex TSR Shares earned Threshold 0% 0% Target + 25% 100% Maximum + 35% 130% Total stockholder return is calculated based on the 90-day average stock price at the beginning and end of the performance period. Linearinterpolation is generally used to determine the number of shares earned for achievement between threshold and target levels and between target andmaximum levels. However, if the Company’s total stockholder return over the performance period is negative, the number of shares earned will be capped at100% of the target number of TSR PSUs.The grant date fair values per share of the Stock Price PSUs and the TSR PSUs were determined by using the Monte-Carlo simulation model, ranging$7.01 to $8.76, respectively. The assumptions used in the Monte-Carlo simulation includes the expected volatility of 54%, risk-free rate of 1.5%, noexpected divided yield, expected term of 3.0 years and possible future stock prices over the performance period based on historical stock and market prices.For the fiscal years ended June 30, 2018, 2017 and 2016, the Company withheld an aggregate of 1.0 million shares, 0.4 million shares and 0.1 millionshares, respectively, upon the vesting of RSUs, based upon the closing share price on the vesting date as settlement of the employees’ minimum statutoryobligation for the applicable income and other employment taxes.For fiscal years 2018, 2017 and 2016, the Company remitted cash of $11.3 million, $2.0 million and $0.2 million, respectively, to the appropriatetaxing authorities on behalf of the employees. The payment of the taxes by the Company reduced the number of shares that would have been issued on thevesting date and was recorded as a reduction of additional paid-in capital in the consolidated balance sheets and as a reduction of “Proceeds from issuance ofcommon stock” in the financing activity within the consolidated statements of cash flows.As of June 30, 2018, there were $41.7 million in unrecognized compensation costs related to non-vested stock awards.

OnNovember 12, 2014, the stockholders approved the 2014 ESPP with the maximum number of shares of common stock that may be issued under the plan of12.0 million shares. The 2014 ESPP replaced the 1999 Employee Stock Purchase Plan. The 2014 ESPP allows eligible employees to acquire shares of theCompany’s common stock through periodic payroll deductions of up to 15% of total compensation, subject to the terms of the specific offering periodsoutstanding. Each purchase period has a maximum duration of six months. The price at which the common stock may be purchased is 85% of the lesser of thefair market value of the Company’s common stock on the first day of the applicable offering period or on the last day of the respective purchase period.During fiscal 2018, the 2014 ESPP had offerings periods of either 6 months or 24 months, commonly referred to as “look back periods”. As of June 30, 2018,there have been 6.6 million shares issued under the 2014 ESPP.Effective with the offering period beginning on February 1, 2016, the Company amended the 2014 ESPP to increase the maximum shares issuable foreach purchase period from 1.0 million shares to 1.5 million shares. Effective with the offering period beginning on August 1, 2016, the Company amendedthe 2014 ESPP so that all future offering periods are limited to six months and to make certain other changes to the 2014 ESPP including adding newcontribution limits for each offering period. Existing open offering periods prior to the effective date of the changes were unaffected by the amendments tothe 2014 ESPP.Share Based Compensation ExpenseShare-based compensation expense recognized in the financial statements by line item caption is as follows (in thousands): Year Ended June 30,2018 June 30,2017 June 30,2016 Cost of product revenue $564 $333 $882 Cost of service revenue 1,131 589 1,041 Research and development 7,642 3,312 4,559 Sales and marketing 9,843 4,253 4,633 General and administrative 8,453 4,146 3,677 Total share-based compensation expense $27,633 $12,633 $14,792 The amount of stock based compensation expense capitalized in inventory has been immaterial for each of the periods presented.The Company uses the straight-line method for expense attribution other than the PSUs using the accelerated attribution method. Beginning in fiscal2017, the Company no longer estimates forfeitures, but rather recognizes expense for those shares expected to vest and recognizes forfeitures when theyoccur. The Company’s estimated forfeiture rate in fiscal 2016 based on the Company’s historical forfeiture experience was 13% for non-executives and 19%for executives.The fair value of each stock option grant under the Company’s 2013 Plan and 2005 Plan is estimated on the date of grant using the Black-Scholes-Merton option valuation model with the weighted average assumptions noted in the following table. The expected term of options granted is derived fromhistorical data on employee exercise and post-vesting employment termination behavior. The risk-free rate is based upon the estimated life of the option andis based on the U.S. Treasury yield curve in effect at the time of grant. Expected volatility is based on a blended rate of the implied volatilities from tradedoptions on the Company’s stock and historical volatility on the Company’s stock.The fair value of each share purchase option under the Company's 2014 ESPP is estimated on the date of grant using the Black-Scholes-Merton optionvaluation model with the weighted average assumptions noted in the following table.

Pursuant to the Plan, employees may elect to reduce their current compensation up to the IRS annual contribution limit of$18,500 for calendar year 2018. Employees age 50 or over may elect to contribute an additional $6,000. The amount contributed to the Plan is on a pre-taxbasis.The Company provides for discretionary matching contributions as determined by the Board of Directors for each calendar year. All matchingcontributions vest immediately. In addition, the Plan provides for discretionary contributions as determined by the Board of Directors each year. Theprogram during fiscal 2018 is to match $0.50 for every Dollar contributed by the employee up to the first 2.5% of pay. The Company’s matchingcontributions to the Plan totaled $3.3 million, $1.4 million and $1.2 million, for fiscal years 2018, 2017 and 2016, respectively. No discretionarycontributions were made in fiscal years 2018, 2017 or 2016. 12. Information about Segments of Geographic AreasThe Company operates in one segment, the development and marketing of network infrastructure equipment. Revenue is attributed to a geographicalarea based on the location of the customers. The Company operates in three geographic theaters: Americas, which includes the United States, Canada,Mexico, Central America and South America; EMEA, which includes Europe, Russia, Middle East and Africa; and APAC which includes Asia Pacific, China,South Asia and Japan. The Company’s chief operating decision maker (“CODM”), who is its CEO, reviews financial information presented on a consolidatedbasis for purposes of allocating resources and evaluating financial performance.

Foreign Exchange Forward ContractsThe Company uses derivative financial instruments to manage exposures to foreign currency. The Company’s objective for holding derivatives is touse the most effective methods to minimize the impact of these exposures. The Company does not enter into derivatives for speculative or tradingpurposes. The fair value of the Company’s derivatives in a gain position are recorded in “Prepaid expenses and other current assets” and derivatives in a lossposition are recorded in “Other accrued liabilities” in the accompanying consolidated balance sheets. Changes in the fair value of derivatives are recorded in“Other income (expense), net” in the accompanying consolidated statements of operations; the Company recognized losses of $1.2 million and $0.7 millionin fiscal 2018 and 2017, respectively, and gains of $1.3 million in fiscal 2016 related to the change in fair value. The Company enters into foreign exchangeforward contracts to mitigate the effect of gains and losses generated by foreign currency transactions related to certain operating expenses andremeasurement of certain assets and liabilities denominated in foreign currencies. These derivatives do not qualify as hedges.89EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) At June 30, 2018 and 2017, forward foreign currency contracts had a notional principal amount of $5.0 million and $6.7 million, respectively. Thesecontracts have maturities of less than 60 days. Changes in the fair value of these foreign exchange forward contracts are offset largely by remeasurement ofthe underlying assets and liabilities. 14. Restructuring and Related Charges, Net of ReversalsAs of June 30, 2018, restructuring liabilities were $6.5 million which are recorded in “Other accrued liabilities” and “Other long-term liabilities” in theaccompanying consolidated balance sheets. The restructuring liabilities consist of obligations pertaining to the estimated future obligations for non-cancelable lease payments and severance and benefits obligations. During fiscal years 2018, 2017 and 2016, the Company recorded restructuring charges,net of reversals, of $8.1 million, $8.9 million and $11.0 million, respectively. The charges are reflected in “Restructuring and related charges, net ofreversals” in the consolidated statements of operations. 2018 RestructuringThe Company announced and began executing a reduction-in-force in its third and fourth fiscal quarters as a result of the acquisitions of the CampusFabric Business and the Data Center Business. The Company recorded $7.9 million related to employee severance and benefits expenses during the yearended June 30, 2018. The Company also incurred charges of $0.2 million for changes to its estimates for accrued lease costs pertaining to the estimatedfuture obligations for non-cancelable lease payments of its excess facilities.2017 RestructuringIn conjunction with the Company’s restructuring activities noted below, the Company incurred $8.9 million of restructuring charges, net ofreversals during fiscal 2017 which is reflected in “Restructuring and related charges, net of reversals” in the consolidated statements of operations.Pursuant with the WLAN Business acquisition from Zebra, the Company assumed a facility lease located at 6480 Via del Oro in San Jose, California(“Via del Oro”) and transferred the Company’s headquarters from Rio Robles Drive in San Jose, California (“Rio Robles”) to Via del Oro. The Companyconsolidated its existing workforce with employees assumed from Zebra at the Via del Oro site and exited the Rio Robles site on January 31, 2017. Due tothe Company’s move from the Rio Robles facility and abandonment of all leasehold improvements, it accelerated the amortization of the remainingleasehold improvements balance for this site over the shortened service period such that the leasehold improvements were fully amortized on the cease-usedate. The Company recorded accelerated amortization expense for the year ended June 30, 2018 of $2.6 million. The Company entered into a sublease agreement for its Rio Robles facility during the third quarter of fiscal 2017. The sublease is for the remainingduration of the Company’s lease. The net charges incurred for the remaining lease payments, real estate commissions and other related costs, net of the futuresublease payments resulted in additional charges of $2.0 million during fiscal 2017. The excess facilities payments will continue through fiscal year 2023.In anticipation of the acquisitions of the Campus Fabric and the Data Center Businesses, the Company reoccupied the majority of its exited space atits Salem, New Hampshire location during its fiscal fourth quarter to accommodate the growth in headcount and lab facility requirements. This actionresulted in a reversal of prior accruals of $1.3 million.In conjunction with the consolidation actions noted above, the Company announced a reduction-in-force affecting 90 employees. The Companyrecorded $5.6 million in severance and benefits charges, net during the year ended June 30, 2017. 2016 RestructuringDuring fiscal 2016, the Company abandoned excess facilities, primarily in San Jose, California; Salem, New Hampshire; Morrisville, North Carolinaand other smaller leased locations. The abandoned facilities represented approximately 32% of the floor space in the aggregate at these locations andincluded general office and warehouse space.In conjunction with the exiting of facilities noted above, the Company incurred $11.0 million of restructuring charges. Excess facilities chargesincluded accrued lease costs pertaining to the estimated future obligations for non-cancelable lease payments for excess facilities and contract terminationcharges of $5.4 million, acceleration of depreciation of leasehold improvements of $4.5 million, professional fees of $1.0 million and other of $0.1 million.90EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Significant restructuring charges incurred during 2016, by location, included $1.8 million of charges for excess facilities pertaining to the estimatedfuture obligations for non-cancelable lease payments at Rio Robles. This represented 39% of the San Jose leased space. The Company amended its facilitylease at its North Carolina location and exited excess space while recording $4.1 million of charges, which included $3.1 million in accelerated depreciationof leasehold improvements. This action represented 36% of the North Carolina location lease space.

The Company has provided a full valuation allowance against all of its U.S. federal and state deferred tax assets, as well asvaluation allowances against non-U.S. deferred tax assets in Australia and Brazil. The valuation allowance is determined by assessing both negative andpositive available evidence to assess whether it is more likely than not that the deferred tax assets will be recoverable. The Company's inconsistent earningsin recent periods, including a cumulative loss over the last three years, coupled with its difficulty in forecasting future revenue trends as well as the cyclicalnature of the Company's business provides sufficient negative evidence to require a full valuation allowance against its U.S. federal and state net deferred taxassets. The valuation allowance is evaluated periodically and can be reversed partially or in full if business results and the economic environment havesufficiently improved to support realization of the Company's deferred tax assets.As of June 30, 2018, the Company had net operating loss carry-forwards for U.S. federal and state tax purposes of $185.6 million and $54.4 million,respectively. As of June 30, 2018, the Company also had foreign net operating loss carry-forwards in Ireland, Australia and Brazil of $37.5 million, $9.0million and $0.7 million, respectively. As of June 30, 2018, the Company also had federal and state tax credit carry-forwards of $33.2 million and $18.8million, respectively. These credit carry-forwards consist of research and development tax credits as well as foreign tax credits. The U.S. federal net operatingloss carry-forwards of $185.6 million will begin to expire in the fiscal year ending June 30, 2021 and state net operating losses of $54.4 million began topartially expire in the fiscal year ending June 30, 2018. The foreign net operating losses can generally be carried forward indefinitely. Federal research anddevelopment tax credits of $22.6 million will expire beginning in fiscal 2019, if not utilized and foreign tax credits of $10.6 million will expire beginning infiscal 2020. North Carolina state research and development tax credits of $0.9 million will expire beginning in the fiscal year ending June 30, 2024, if notutilized. California state research and development tax credits of $17.9 million do not expire and can be carried forward indefinitely.In September, 2017, the Company performed an Internal Revenue Code section 382 analysis with respect to its net operating loss and credit carry-forwards to determine whether a potential ownership change had occurred that would place a limitation on the annual utilization of tax attributes. It wasdetermined that no ownership change had occurred during the fiscal year ended June 30, 2017, however, it is possible a subsequent ownership change couldlimit the utilization of the Company's tax attributes.93EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) As of June 30, 2018, cumulative undistributed, indefinitely reinvested earnings of non-U.S. subsidiaries totaled $14.1 million. It has been theCompany’s historical policy to invest the earnings of certain foreign subsidiaries indefinitely outside the US. As discussed below, recently enacted taxreform includes a provision to move the U.S. to a modified territorial tax system by imposing a transition tax on historic foreign earnings whether or not suchearnings are repatriated to the U.S. The Company has determined there will be no cash tax impact of this new provision due to existing tax attributes. TheCompany is reviewing its prior position on the reinvestment of earnings of certain foreign subsidiaries but has recorded a deferred tax liability of $0.4 millionrelated to withholding taxes that may be incurred upon repatriation of earnings from jurisdictions where no indefinite reinvestment assertion is made. TheCompany continues to maintain an indefinite reinvestment assertion for earnings in certain of its foreign jurisdictions. The unrecorded deferred tax liabilityfor potential withholding tax associated with repatriation of these earnings is $2.7 million.The Company conducts business globally and as a result, most of its subsidiaries file income tax returns in various domestic and foreignjurisdictions. In the normal course of business, the Company is subject to examination by taxing authorities throughout the world. Its major tax jurisdictionsare the U.S., Ireland, India, California, New Hampshire and North Carolina. As of June 30, 2017, the Company is currently under examination by the state ofNorth Carolina for the fiscal years ended 2014, 2015 and 2016. In general, the Company's U.S. federal income tax returns are subject to examination by taxauthorities for fiscal years 2001 forward due to net operating losses and the Company's state income tax returns are subject to examination for fiscal years2000 forward due to net operating losses.On December 22, 2017, the President of the United States signed and enacted into law H.R. 1, the Tax Cuts and Jobs Act (“TCJA”), which, except forcertain provisions, is effective for tax years beginning on or after January 1, 2018. As a fiscal year taxpayer, the Company will not be subject to the majorityof the tax law provisions until fiscal year 2019; however, there are certain significant items of impact that will be recognized in fiscal year 2018. Because achange in tax law is accounted for in the period of enactment, the effects of the TCJA, a tax benefit of $2.5 million, was reflected in the full year results forfiscal 2018.The TCJA’s primary change is a reduction in the U.S. Federal statutory corporate tax rate from 35% to 21%, including a pro rata reduction from 35% to28% for the Company in fiscal 2018. As a result, the Company recognized a tax benefit in the amount of $2.5 million in the second quarter of fiscal 2018due to the revaluation of the Company's deferred tax liability related to amortizable goodwill to reflect the lower statutory rate. Because the U.S. deferred taxassets are offset by a full valuation allowance, the reduction in deferred tax assets for the lower rate was fully offset by a corresponding reduction in valuationallowance resulting in no additional tax provision.The TCJA moves the U.S. from a global taxation regime to a modified territorial regime. Under the territorial regime, the company’s foreign earningswill generally not be subject to tax in the US. As part of transitioning to this new regime, U.S. companies are required to pay tax on historical earningsgenerated offshore that have not been repatriated to the U.S. (“Transition Tax”). The Company has estimated there will be no incremental tax provisionrelating to the Transition Tax given the Company’s ability to utilize existing tax attributes to offset the impact of the deemed repatriation.The TCJA makes broad and complex changes to the U.S. tax code, and in certain instances, lacks clarity and is subject to interpretation untiladditional U.S. Treasury guidance is issued. On December 22, 2017, the SEC issued guidance under Staff Accounting Bulletin No. 118, Income TaxAccounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which allows registrants to record provisional amounts during a one year “measurementperiod” similar to that used when accounting for business combinations. However, the measurement period is deemed to have ended earlier when theregistrant has obtained, prepared and analyzed the information necessary to finalize its accounting. During the measurement period, impacts of the law areexpected to be recorded at the time a reasonable estimate for all or a portion of the effects can be made, and provisional amounts can be recognized andadjusted as information becomes available, prepared or analyzed. The SAB summarizes a three-step process to be applied at each reporting period to accountfor and qualitatively disclose: (1) the effects of the change in tax law for which accounting is complete; (2) provisional amounts (or adjustments toprovisional amounts) for the effects of the tax law where accounting is not complete, but that a reasonable estimate has been determined; and (3) a reasonableestimate cannot yet be made and therefore taxes are reflected in accordance with law prior to the enactment of the TCJA.94EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Amounts recorded where accounting is complete in the year ended June 30, 2018 principally relate to the reduction in the U.S. federal tax rate to 21percent, which resulted in the Company reporting an income tax benefit of $2.5 million to remeasure deferred tax liabilities associated with indefinitely livedintangible assets that will reverse at the new 21% rate. Absent this deferred tax liability, the Company is in a net deferred tax asset position that is offset by afull valuation allowance. The impact of the rate change related to net deferred tax assets has a net tax effect of zero, and as such, the accounting to determinethe gross change in the deferred tax position and the offsetting valuation is considered complete. In accordance with Staff Accounting Bulletin (“SAB”) 118,the estimated income tax impact associated with the Transition Tax of zero represents our best estimate based on interpretation of the U.S. legislation as weare still accumulating data to finalize the underlying calculation. In accordance with SAB 118, estimated income tax impact associated with the TransitionTax is considered provisional and will be finalized prior to the end of the measurement period. The ultimate impact may differ from these provisionalamounts, due to, among other things, additional analysis, changes in interpretations and assumptions the Company has made, additional regulatory guidancethat may be issued, and actions the Company may take as a result of the TCJA.With respect to provisions of the TCJA effective for tax years beginning on or after January 1, 2018, the company anticipates several new provisionsmay potentially impact tax provisions in future periods including limitations on the deductibility of interest expense and certain executive compensation, aminimum tax on certain foreign earnings (i.e., global intangible low-taxed income or “GILTI”), as well as a base-erosion and anti-abuse tax (“BEAT”). TheGILTI provisions require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreignsubsidiary’s tangible assets. Based on initial assessment and interpretation of the new provision, the Company expects that it will be subject to incrementalU.S. tax on GILTI income beginning in fiscal 2019. The Company may elect to account for GILTI tax as a component of tax expense in the period in which itis incurred or account for the GILTI tax in the measurement of deferred taxes. The Company is continuing to evaluate this particular provision and thereforehas not yet elected a method but will do so once our analysis is complete. The BEAT provisions in the Tax Reform Act eliminate the deduction of certainbase-erosion payments made to related foreign corporations, and impose a minimum tax if greater than regular tax. There is a reasonable amount ofuncertainty surrounding the interpretation of this new provision, however, based on initial assessment and a conservative interpretation of the new provision,the Company expects that it will be minimally subject to the incremental U.S. tax on BEAT income beginning in fiscal 2019.During the fiscal year ended June 30, 2014, the Company acquired the stock of Enterasys Networks, Inc. and as such they became a wholly ownedsubsidiary of Extreme Networks. With respect to this acquisition, the Company made an election under Internal Revenue Code section 338(h)(10) to treat theacquisition as an asset purchase from a tax perspective. Under this election the tax basis of all assets is effectively reset to that of fair market value andtherefore the transaction did not result in the recording of an opening net deferred tax position as the Company's tax basis in the acquired assets equaled itsbook basis. The resulting intangible assets and goodwill are being amortized for tax purposes over 15 years.Additionally, the Company completed the acquisitions of the Zebra WLAN Business, the Avaya Campus Fabric Business and the Brocade Data CenterBusiness in October 2016, July 2017 and October 2017, respectively, and treats the acquisitions as an asset purchase from a tax perspective. The Companyhas estimated the value of the intangible assets from these transactions and is amortizing the amounts over 15 years for tax purposes. During the twelve months ended June 30, 2018, the Company deducted $7.5 million of tax amortization expense related to capitalized goodwillresulting from the above acquisitions.As of June 30, 2018, the Company had $17.5 million of unrecognized tax benefits. If fully recognized in the future, there would be no impact to theeffective tax rate, and $17.5 million would result in adjustments to deferred tax assets and corresponding adjustments to the valuation allowance. TheCompany does not reasonably expect the amount of unrealized tax benefits to decrease during the next twelve months. The increase for fiscal year 2018relates substantially to previously unrecorded foreign net operating losses.95EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) A reconciliation of the beginning and ending amount of total unrecognized tax benefits is as follows (in thousands):Balance at June 30, 2015 $11,359 Increase related to prior year tax positions 174 Lapse of statute of limitations 120 Balance at June 30, 2016 11,653 Increase related to prior year tax positions 7,180 Increase related to current year tax positions 233 Lapse of statute of limitations (153)Balance at June 30, 2017 18,913 Decrease related to prior year tax positions (1,407)Balance at June 30, 2018 $17,506Estimated interest and penalties related to the underpayment of income taxes, if any are classified as a component of tax expense in the consolidatedstatement of operations and totaled less than $0.1 million for each of the fiscal years 2018, 2017 and 2016. 16. Net Loss Per ShareBasic earnings per share is calculated by dividing net income by the weighted average number of common shares outstanding during the period, lessshares subject to repurchase, and excludes any dilutive effects of options, warrants and unvested restricted stock. Dilutive earnings per share is calculated bydividing net income by the weighted average number of common shares used in the basic earnings per share calculation plus the dilutive effect of sharessubject to options, warrants and unvested restricted stock. The following table presents the calculation of basic and diluted net loss per share (in thousands,except per share data): Year Ended June 30,2018 June 30,2017 June 30,2016 (As Adjusted) (As Adjusted) Net loss $(46,792) $(1,744) $(36,363)Weighted-average shares used in per share calculation - basic and diluted 114,221 108,273 103,074 Net loss per share - basic and diluted $(0.41) $(0.02) $(0.35)Potentially dilutive common shares from employee incentive plans are determined by applying the treasury stock method to the assumed exercise ofoutstanding stock options, the assumed vesting of outstanding restricted stock units, and the assumed issuance of common stock under the ESPP. Weightedstock options outstanding with an exercise price higher than the Company's average stock price for the periods presented are excluded from the calculation ofdiluted net loss per share since the effect of including them would have been anti-dilutive due to the net loss position of the Company during the periodspresented.The following securities were excluded from the computation of outstanding diluted earnings per common share because they would have been anti-dilutive (in thousands): Year Ended June 30,2018 June 30,2017 June 30,2016 Options to purchase common stock 2,547 — 6,937 Restricted stock units 7,822 220 353 Employee Stock Purchase Plan shares 1,294 — — Total shares excluded 11,663 220 7,290 Item 9. Changes in and Disagreements with Accountants on Accounting and Financial DisclosureNone.96EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Item 9A. Controls and ProceduresEvaluation of Disclosure Controls and ProceduresDisclosure controls and procedures are controls and procedures designed to reasonably assure that information required to be disclosed in our reportsfiled under the Securities Exchange Act of 1934 as amended, such as this Report, is recorded, processed, summarized and reported within the time periodsspecified in the SEC’s rules and forms and to reasonably assure that such information is accumulated and communicated to our management, including theChief Executive Officer (“CEO”) and the Chief Financial Officer (“CFO”), as appropriate to allow timely decisions regarding required disclosure.Under the supervision and with the participation of our management, including our CEO and CFO, we evaluated the effectiveness of the design andoperation of our disclosure controls and procedures as of the end of the period covered by this Report. Based on this evaluation, our CEO and CFO concludedthat our disclosure controls and procedures were effective as of June 30, 2018.Management’s Report on Internal Control over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over our financial reporting. There are inherent limitationsin the effectiveness of any system of internal control, including the possibility of human error and the circumvention or overriding of controls. Accordingly,even effective internal controls can provide only reasonable assurances with respect to financial statement preparation. Further because of changes inconditions, the effectiveness of internal control may vary over time.We assessed the effectiveness of our internal control over financial reporting as of June 30, 2018. In making this assessment, we used the criteria setforth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control-Integrated Framework (2013). Based on ourassessment using those criteria, we concluded that, as of June 30, 2018, our internal control over financial reporting is effective.During the year ended June 30, 2018, we completed our acquisitions of the fabric-based secure networking solutions and network security solutionsbusiness (the “Campus Fabric Business”) from Avaya Inc., the data center business (the “Data Center Business”) from Brocade Communication Systems, Inc.,and the capital financing business (the “CF Business”) from Broadcom Corporation. In conducting our evaluation of the effectiveness of our internal controlsover financial reporting as of June 30, 2018, we have elected to exclude the Campus Fabric Business, Data Center Business and CF Business from ourevaluation for fiscal 2018 as permitted under current Securities and Exchange Commission rules and regulations. As of and for the year ended June 30, 2018,the assets and revenues of the acquired businesses not included in our evaluation represented 20% of consolidated assets and 33% of consolidated revenues.We are currently in the process of integrating and assessing the internal controls over financial reporting of the acquired businesses with the rest of ourCompany. The integration may lead to changes in future periods, but we do not expect these changes to materially affect our internal controls over financialreporting. We expect to complete this integration in fiscal 2019.Our independent registered public accounting firm, KPMG LLP, has audited the financial statements included in this Annual Report on Form 10-Kand has issued its report on our internal control over financial reporting as of June 30, 2018.Changes in Internal Control over Financial ReportingThere were no changes in our internal control over financial reporting during the quarter ended June 30, 2018, that have materially affected, or arereasonably likely to materially affect, our internal control over financial reporting.97EXTREME NETWORKS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Inherent Limitations on Effectiveness of ControlsOur management, including the CEO and CFO, does not expect that our disclosure controls or our internal control over financial reporting willprevent or detect all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurancethat the control system’s objectives will be met. Our controls and procedures are designed to provide reasonable assurance that our control system’s objectivewill be met and our CEO and CFO have concluded that our disclosure controls and procedures are effective at the reasonable assurance level. The design of acontrol system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, becauseof the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will notoccur or that all control issues and instances of fraud, if any, within Extreme have been detected. These inherent limitations include the realities thatjudgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by theindividual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is basedin part on certain assumptions about the likelihood of future events. Projections of any evaluation of the effectiveness of controls in future periods are subjectto risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies orprocedures. Notwithstanding these limitations, our disclosure controls and procedures are designed to provide reasonable assurance of achieving theirobjectives. Our CEO and CFO have concluded that our disclosure controls and procedures are, in fact, effective at the “reasonable assurance” level.Item 9B.
