BUSINESSGeneral Background and Product OfferingsDigi International Inc. ("Digi," "we," "our," or "us") was incorporated in 1985 as a Minnesota corporation. We were reorganized as a Delaware corporation in1989 in conjunction with our initial public offering. Our common stock is traded on the NASDAQ Global Select Market under the symbol DGII. Our WorldHeadquarters is located at 11001 Bren Road East, Minnetonka, Minnesota 55343. The telephone number at our World Headquarters is (952) 912-3444.We are a leading global provider of business and mission-critical and Internet of Things (IoT) connectivity products and services. We help our customerscreate next-generation connected products and deploy and manage critical communications infrastructures in demanding environments with high levels ofsecurity and reliability. As of the fiscal quarter ended June 30, 2017, we determined that we have two reportable operating segments for purposes of ASC 280-10-50 "Segments Reporting": (i) machine-to-machine (M2M), and (ii) Solutions.Our M2M segment consists primarily of distinct communications products and communication product development services. Among other things, theseproducts and services help our customers create next generation connected products and deploy and manage critical communications infrastructures indemanding environments with high levels of security and reliability. This segment creates secure, easy to implement embedded solutions and services to helpcustomers build IoT connectivity. It also deploys ready to use, complete box solutions to connect remote equipment. The M2M segment also offers dedicatedprofessional services for the design of specialized wireless communications products for customers. Finally, this segment offers managed cloud services thatenable customers to capture and manage data from devices they connect to networks. M2M products and services are used by a wide range of businesses andinstitutions.Our Solutions segment offers wireless temperature and other environmental condition monitoring services as well as employee task management services.These products and services are provided to food service, transportation, education, healthcare and pharma, and industrial markets and are marketed as DigiSmart Solutions™. We have formed and expanded the Solutions segment primarily through four acquisitions: the October 2015 acquisition of BluenicaCorporation (Bluenica), the November 2016 acquisition of FreshTemp, LLC (FreshTemp), the January 2017 acquisition of SMART Temps, LLC (SMARTTemps) and the October 2017 acquisition of TempAlert, LLC (TempAlert). Because the acquisition of TempAlert was subsequent to September 30, 2017, it'sresults are not included in our Consolidated Financial Statements (see Note 19 to our Consolidated Financial Statements).For more in-depth descriptions of our primary products and services, please refer to the heading "Listing of Principal Products and Services" at the end of PartI, Item 1 of this Form 10-K.In October 2015, we sold our Etherios, Inc. customer relationship management (CRM) consulting services business (Etherios), which focused on integrationand configuration of enterprise resource management (ERM) systems, including CRM systems. This part of our business principally provided integration andconfiguration of salesforce.com products. As a result of the sale of Etherios, we have accounted for it as a discontinued operation. Accordingly, amounts inthe Consolidated Statement of Operations, the Consolidated Balance Sheets and notes thereto, for all periods affected, have been reclassified to reflectdiscontinued operations accounting for that business. For more information on this divestiture see Note 3 to the Consolidated Financial Statements.Our M2M revenue represented 95.9%, 99.6% and 100.0% of our total revenue during the fiscal years ended September 30, 2017, 2016 and 2015,respectively. Solutions revenue represented 4.1% and 0.4% of our total revenue in fiscal 2017 and 2016, respectively. We had no Solutions revenue in fiscal2015.Our corporate website address is www.digi.com.

Our M2M segment sells both wired and wireless products that are eitherembedded into the products of original equipment manufacturers (OEMs) or stand-alone to provide connectivity to stand-alone assets of customers. Certainof these products have been sold for many years, are in the mature phase of their life cycle and have been experiencing declining sales for several years. Infiscal 2017, sales of these legacy products experienced larger than expected declines largely because a long-term customer of certain of these productssignificantly curtailed its purchase of our products in fiscal 2017. These declines were not offset by increases in sales of other products, which, among otherissues, were hampered by delays in the release of new products. While we generally expect the trend of marketplace growth to continue, it is susceptible todownturns either because of general economic conditions, the continued development of technology and uncertainty or changes in the regulatoryenvironments. Relative to our own M2M segment business, sales of many of our products are subject to large project-based customer deployments. As such, ifwe are unable to identify and commence new deployments with equal or greater significance than completed projects, our growth from period to period maybe inconsistent and our M2M segment may in any given period contract.While the performance of our M2M segment, which is the significant majority of our sales, was less than anticipated in fiscal 2017, our Solutions segmentexperienced significant growth as we completed the acquisitions of FreshTemp and SMART Temps in our first and second fiscal quarters, respectively. Wecontinue to see steadily growing demand for our Solutions products and services and presently expect this trend to continue.StrategyWe continue to take significant steps to transform Digi into a company that can deliver consistent long-term growth with higher levels of profitability. Thistransformation began when we appointed Ronald E. Konezny as our Chief Executive Officer in December 2014 and today is centered on managing each ofour operating segments towards different primary objectives.M2M SegmentOur M2M segment, which represents the significant majority of our revenues is being managed for modest revenue growth and higher levels of profitabilitythrough greater operating expense leverage. A significant part of this business remains based in legacy networking products that are in the mature phase oftheir product life cycles. For many years these products have been experiencing year over year revenue declines that create a natural headwind to drivingsignificant growth in this operating segment as a whole. In addition, sales of many of our products throughout this segment are based on significant one timeprojects. As a result, for many years Digi has experienced inconsistent revenue growth as project based revenues have fluctuated.In this operating environment we have taken the following steps to meet our aims:•We sold our Etherios CRM consulting business in 2015. This business initially was acquired with the expectation it would drive engagements withcompanies that utilize the salesforce.com platform and were looking to deploy solutions within their businesses. We were not, however, rewarded inthe marketplace as we had expected. As a result, we disposed of a consulting business that was losing money and not fully tied to our core hardwareexpertise.•We significantly reduced the number of hardware product stock keeping units (SKUs) we produce in order to simplify our operations, improve ourability to manage inventory effectively, improve channel stocking strategies and control costs. At present, SKUs have been reduced from close to5,000 at the beginning of fiscal 2016 to approximately 1,400.•We consolidated and relocated office locations to improve efficiencies and provide costs savings. In the first quarter of fiscal 2016, we moved ourDigi Wireless Design Services team from an office in downtown Minneapolis to our World Headquarters in suburban Minnetonka. In the thirdquarter of fiscal 2016, we closed our office in Dortmund, Germany and moved the corresponding positions to our existing office in Munich,Germany. In the third quarter of fiscal 2017, we announced the closure of our Paris, France office to further consolidate European operations in2Table of ContentsMunich, Germany. These moves improved our operating expenses and better position our employees to drive positive results in our operationsthrough increased collaboration.•In October 2017, we have added new leadership to our M2M team in the areas of product management and research and development to drivegreater alignment around the products we bring to market to meet the needs and desires of potential customers in key markets in a timely manner.We believe this increased alignment can greater lever our technical capabilities to drive more consistent growth.Solutions SegmentOur Solutions segment, which has grown from no revenue during fiscal 2015 to almost 5% of our total revenue in fiscal 2017, is being managed primarily forrevenue growth. The segment was formed and has been grown primarily through our acquisitions of Bluenica in October 2015, FreshTemp in November2016, SMART Temps in January 2017 and, most recently, TempAlert in October 2017. Following our acquisition of TempAlert we believe in fiscal 2018 thisbusiness will deliver between 10-15% of our revenues.This business helps businesses track the completion of employee tasks and monitor environmental conditions (most notably, temperature) of perishable orsensitive inventories. Our efforts have created a market-leading, high-growth hardware enabled service business with significant recurring revenue potential.Following our recent TempAlert acquisition we now serve over 35,000 customer sites for many leading brands in the foodservice, transportation, education,healthcare and pharma and industrial marketplaces.We have chosen to enter this marketplace aggressively for several reasons. First, it provides us with the opportunity to develop a recurring revenue businessthat is focused on a large addressable market that has not been penetrated significantly. Restaurants, pharmacies, hospitals and other businesses that maintainsignificant inventories of perishable or other sensitive goods are a large part of the market. These businesses by and large presently rely primarily onemployees to log the temperature or other environmental conditions of these goods as well as the completion of other tasks using pencil and paper. This isnot as cost effective or secure as using wireless communications sensors to track conditions automatically and provide real time alerts if establishedparameters are breached. It also is not as effective for tracking the completion of other tasks as using an application enabled smart phone or other wirelesscommunications device. Second, at present this marketplace primarily is served by smaller companies that lack the infrastructure to provide hardware enabledservice to customers in as effective and efficient a manner as we are able to do because of our long-standing history as an IoT hardware provider. Third, webelieve customers in this marketplace will not require significant customization or development of existing products before they will commit to purchase thesolution. This differs from many of our hardware customers who often ask us to create a highly customized product that cannot be easily sold to other parties.This potential for repeatable sales of an established product suite appeals to us. Fourth, by protecting valuable goods that impact health and safety, thesolution provides a clear return on investment for potential customers whose business and reputation is highly reliant on maintaining safe operations that willnot harm customers.We believe this marketplace represents an opportunity for significant revenue growth for Digi that is both recurring and high-margin in nature. To that end atpresent our primary aim with this business is to manage it for customer acquisition and revenue growth while assuring we do not negatively impact theoverall profitability of the Company in any material way.In summary, we intend to continue to take steps to simplify our operations, improve operating expenses to increase our profit leverage and expand ourbusiness in ways that we believe can drive long-term profitable growth. We will continue to seek and evaluate acquisitions that will further enhance ourSolutions segment as we believe this marketplace offers a path to a significant base of recurring revenue that can provide both stability and significantgrowth for us. We may also seek to acquire hardware or other businesses that we believe can improve our market position in our M2M segment.Acquisitions and DispositionsAcquisitionsSince fiscal 2015 we have acquired four businesses that form the basis of our Solutions segment.In October 2015, we acquired Ontario based Bluenica, a company focused on temperature monitoring of perishable goods in the food industry by usingwireless sensors which are installed in grocery and convenience stores, restaurants, and in products during shipment and storage to ensure that quality,freshness and public health requirements are met (see Note 2 to our Consolidated Financial Statements).3Table of ContentsIn November 2016, we acquired Pittsburgh based FreshTemp. FreshTemp offered restaurants, convenience stores and other retailers the ability to monitor thetemperature of food products automatically through the use of wireless sensors. The company also enabled these businesses to track the completion ofoperational tasks by their employees that could impact human health and safety in real time - a capability that we believe significantly enhanced our productoffering (see Note 2 to our Consolidated Financial Statements).In January 2017, we acquired Indiana based SMART Temps. SMART Temps provided real-time foodservice temperature management for restaurant, grocery,education and hospital settings as well as real-time temperature management for pharmacy, blood bank and laboratory environments. The acquisitionsignificantly expanded our customer base, especially in the pharmacy and education marketplaces (see Note 2 to our Consolidated Financial Statements).On October 20, 2017, subsequent to the end of fiscal 2017, we acquired TempAlert, a provider of automated, real-time temperature monitoring and taskmanagement solutions for the healthcare, industrial and foodservice industries. This acquisition more than doubled the number of customer sites we monitorwhile enhancing our ability to analyze data collected from our services. Because the acquisition of TempAlert was subsequent to September 30, 2017,TempAlert is not included in our Consolidated Financial Statements (see Note 19 to our Consolidated Financial Statements).DispositionOn October 23, 2015, we entered into a stock purchase agreement with West Monroe Partners, LLC, pursuant to which they acquired our Etherios CRMconsulting services business. We sold Etherios as part of a strategy to focus on providing highly reliable machine connectivity solutions for business andmission-critical application environments (see Note 3 to our Consolidated Financial Statements).These are the only acquisitions and dispositions we have completed in the past five years. We will continue to evaluate strategic opportunities to acquirebusinesses as they arise and may seek to divest businesses or assets we no longer consider appropriate to our long-term strategy.Sales ChannelsWe sell our products through a global network of distributors, systems integrators and value added resellers (VARs) which accounted for 61.5%, 66.1% and61.8% of our total revenue in fiscal 2017, 2016 and 2015, respectively. We also complete sales through our own dedicated sales organization to OEMs andother customers which accounted for 38.5%, 33.9% and 38.2% of our total revenue in fiscal 2017, 2016 and 2015, respectively.DistributorsOur larger distributors, based on sales we make to them, include Anewtech Systems Pte Ltd., Arrow Electronics, Inc., Astone Technologies, AtlantikElektronik GmbH, Avnet, Digi-Key Corporation, Express Systems & Peripherals, Future Electronics, Ingram Micro, Mouser Electronics, Novotech, SapplyPty. Ltd., Solid State Supplies, Ltd., Sphinx Computer Vertriebs GmbH, Synnex, Tech Data Corporation and Tokyo Electron Device Ltd. We also maintainrelationships with many other distributors in the U.S., Canada, Europe, Asia Pacific and Latin America.Strategic Sales RelationshipsWe maintain alliances with other industry leaders to develop and market technology solutions. These include many major communications hardware andsoftware vendors, operating system suppliers, computer hardware manufacturers, enterprise application providers and cellular carriers. Among others, partnersinclude: AT&T, Bell Mobility, NXP, Telit, Rogers, Silicon Laboratories, Sprint, Telus, Verizon and several other cellular carriers worldwide. Furthermore, wemaintain a worldwide network of authorized developers that extends our reach into certain other technology applications and geographical regions.We have established relationships with equipment vendors in a range of industries such as energy, industrial, retail, transportation, medical, and governmentthat allow the vendors to ship our products and services as component parts of their overall solutions. Our products are used by many of the world’s leadingtelecommunications companies and Internet service providers, including AT&T Inc., Sprint Corporation and Verizon Communications Inc.No single customer comprised more than 10% of our consolidated revenue for any of the years ended September 30, 2017, 2016 or 2015.4Table of ContentsCompetitionWe compete primarily in the communications technology industry, which is characterized by rapid technological advances and evolving industry standards.The market can be affected significantly by new product introductions and marketing activities of industry participants. In addition, we may compete withother companies to acquire new businesses or technologies and the competition to secure such assets may be intense. We compete for customers on the basisof existing and planned product features, service and software application capabilities, company reputation, brand recognition, technical support, alliancerelationships, quality and reliability, product development capabilities, price and availability. While no competitor offers a comparable range of productsand services, various companies do compete with us with respect to one or more of our products or solutions. With respect to many of our product and serviceofferings, we face competition from companies who dedicate more resources and attention to that particular offering than we are able to do given the breadthof our business. As the marketplace for IoT connectivity products and solutions continues to grow, we expect to encounter increased competition. Some ofthese competitors may have access to significantly more financial and technical resources than we possess.Manufacturing OperationsOur manufacturing operations are conducted through a combination of internal manufacturing and external subcontractors specializing in various parts of themanufacturing process. We rely on third party foundries for our semiconductor devices that are Application Specific Integrated Circuits (ASICs) and weoutsource printed circuit board production. This approach allows us to reduce our fixed costs, maintain production flexibility and optimize our profits.Our products are manufactured to our designs with standard and custom components. Most of the components are available from multiple vendors. We haveseveral single-sourced supplier relationships, either because alternative sources are not available or because the relationship is advantageous to us. If thesesuppliers are unable to provide a timely and reliable supply of components, we could experience manufacturing delays that could adversely affect ourconsolidated results of operations in a material way.SeasonalityIn general, our business is not considered to be highly seasonal, although our first fiscal quarter revenue is often less than other quarters due to holidays andfewer shipping days.Working CapitalWe fund our business operations through a combination of cash and cash equivalents, marketable securities and cash generated from operations. We believethat our current financial resources, cash generated from operations, and our capacity for debt and/or equity financing will be sufficient to fund our businessoperations for the next twelve months and beyond.Research & Development and Intellectual Property RightsDuring fiscal 2017, 2016 and 2015, our research and development expenditures were $28.6 million, $31.0 million and $29.9 million, respectively.Due to rapidly changing technology in the communications technology industry, we believe a large part of our success depends upon the product and servicedevelopment skills of our personnel as well as our ability to integrate any acquired technologies with organically developed technologies. While we dedicatesignificant resources to research and development, many of our competitors are focused on a smaller set of products than us and are likely able to dedicatemore resources than us toward the portions of the market in which we compete.Our proprietary rights and technology are protected by a combination of copyrights, patents, trade secrets and trademarks.We have established common law and registered trademark rights on a family of marks for a number of our products. Our products and services primarily aresold under the Digi, Rabbit® and Xbee® brands. We believe that the Digi and Rabbit® brands have established strong identities with our targeted customerbase and our customers associate the Digi brand with "reliability" and the Rabbit® brand with "ease of integration." We believe that our customers associateXbee® with "ease of use." Many of our customers choose us because they are building a very complex system solution and they want the highest level inproduct reliability and ease of integration and use. Our Etherios® brand was sold in connection with the sale of Etherios in October 2015.Our patents are applicable to specific technologies and are valid for varying periods of time based on the date of patent application or patent grant in the U.S.and the legal term of patents in the various foreign countries where patent protection is5Table of Contentsobtained. We believe our intellectual property has significant value and is an important factor in the marketing of our company and products.BacklogBacklog as of both September 30, 2017 and 2016 was $25.3 million. The majority of the backlog at September 30, 2017 is expected to be shipped in fiscal2018. Backlog as of any particular date is not necessarily indicative of our future sales trends.EmployeesWe had 514 employees on September 30, 2017. We consider our relations with our employees to be good.Geographic Areas and Currency RisksOur customers are located throughout North America, Europe, Middle East & Africa (EMEA), Asia Pacific and Latin America. We are exposed to foreigncurrency transaction risk associated with certain sales being denominated in Euros, British Pounds, Japanese Yen and Canadian Dollar and foreign currencytranslation risk as the financial position and operating results of our foreign subsidiaries are translated into U.S. Dollars for consolidation. We manage our netasset or net liability position for U.S. dollar accounts in our foreign locations to reduce our foreign currency risk. We have not implemented a formal hedgingstrategy to reduce foreign currency risk.During 2017, we had approximately $63.9 million of revenue related to foreign customers including export sales, of which $18.2 million was denominated inforeign currency, predominantly the Euro and British Pound. During fiscal 2016 and 2015, we had approximately $71.5 million and $76.2 million,respectively of revenue to foreign customers including export sales, of which $22.9 million and $21.3 million, respectively, were denominated in foreigncurrency, predominantly the Euro and British Pound. In future periods, we expect that the majority of our sales will be in U.S. Dollar.Financial information about geographic areas appears in Note 5 to our Consolidated Financial Statements in this Form 10-K.PRINCIPAL PRODUCTS AND SERVICESOur primary products and services for each operating segment are as follows:M2M SegmentHardware ProductsCellular routers and gateways - Cellular routers provide connectivity for devices over a cellular data network.

Certain of our competitors and potential competitors have or may develop greater financial,technological, manufacturing, marketing, and personnel resources than us either generally or relative to the product sets they sell in competition to us.Further, there are numerous companies competing with us in various segments of the market for our products, and their products may have advantages overour products in areas such as conformity to existing and emerging industry standards, interoperability with other products, management and securitycapabilities, performance, price, ease of use, scalability, reliability, flexibility, product features and technical support.7Table of ContentsOur current and potential competitors have or may develop one or more of the following significant advantages over us in the product areas where theycompete with us:•tighter focus on an individual product or product category;•greater financial, technical and marketing resources;•barriers to transition to our products;•higher brand recognition across larger geographic regions;•more comprehensive functionality;•longer-standing cooperative relationships with OEM and end-user customers;•superior customer service capacity and quality;•longer operating history; and•larger customer base.We cannot provide assurance that we will be able to compete successfully with our current and potential competitors. Such competitors may be able to morequickly develop or adapt to new or emerging technologies and changes in customer requirements, or devote greater resources to the development, promotionand sale of their products. Additionally, it is probable that new competitors or new alliances among existing competitors could emerge and rapidly acquiresignificant market share.Our dependence on new product development and the rapid technological change that characterizes our industry makes us susceptible to loss of marketshare resulting from competitors’ product introductions and enhancements, service capabilities and similar risks.Our industry is characterized by rapidly changing technologies, evolving industry standards, frequent new product introductions, short product life cycles incertain instances and rapidly changing customer requirements. The introduction of products and enhancements embodying new technologies and theemergence of new industry standards can render existing products obsolete and unmarketable.Our future success will depend on our ability to enhance our existing products, to introduce new products to meet changing customer requirements andemerging technologies, and to demonstrate the performance advantages and cost-effectiveness of our products over competing products. Failure by us tomodify our products to support new alternative technologies or failure to achieve widespread customer acceptance of such modified products could cause usto lose market share and cause our revenue to decline. Further, if competitors offer better service capabilities associated with the implementation and use ofproducts in communication networks, our business could be impacted negatively.We may experience delays in developing and marketing product enhancements or new products that respond to technological change, evolving industrystandards and changing customer requirements. For instance, we experienced delays in the introduction of certain new products in fiscal 2017 that impactedour financial results for the year. There can be no assurance that we will not experience difficulties that could delay or prevent the successful development,introduction, and marketing of these products or product enhancements, or that our new products and product enhancements will meet the requirements ofthe marketplace adequately and achieve any significant or sustainable degree of market acceptance in existing or additional markets. In addition, the futureintroductions or announcements of products by us or one of our competitors embodying new technologies or changes in industry standards or customerrequirements could render our then-existing products obsolete or unmarketable. This risk may become more pronounced as new competitors enter themarketplace, especially if these competitors have more resources than us to develop and market new products and technologies and provide related services.There can be no assurance that the introduction or announcement of new product offerings by us or one or more of our competitors will not cause customersto defer their purchase of our existing products, which could cause our revenue to decline.We intend to continue to devote significant resources to our research and development, which, if not successful, could cause a decline in our revenue andharm our business.We intend to continue to devote significant resources to research and development in the coming years to enhance and develop additional products. Forfiscal 2017, 2016, and 2015, respectively, our research and development expenses were 15.7%, 15.2% and 14.7% of our revenue. If we are unable to developnew products, applications and services as a result of our research and8Table of Contentsdevelopment efforts, if we encounter delays in deploying these new products, applications and services, or if the products, applications and services wedevelop are not successful, our business could be harmed. Even if we develop new products, applications and services that are accepted by our target markets,the net revenue from these products, applications and services may not be sufficient to justify our investment in research and development.Many of our products, applications and services have been developed through a combination of internally developed technologies and acquiredtechnologies. Our ability to continue to develop new products, applications and services could be partially dependent on finding and acquiring newtechnologies in the marketplace. Even if we identify new technologies that we believe would be complementary to our internally developed technologies, wemay not be successful in obtaining those technologies or we may not be able to acquire the technologies at a price that is acceptable to us.A substantial portion of our development efforts have been directed toward the development of new products targeted to manufacturers of intelligent,network-enabled devices and other embedded systems in various markets, including markets in which networking solutions for embedded systems have nothistorically been sold, such as markets for industrial automation equipment and medical equipment.Our participation in a services and solutions model, using hardware and cloud-based services, presents execution and competitive risks.We are deploying a services and solutions model. Our Digi Smart Solutions™ offerings deploy hardware, software and cloud-based hosting. In other parts ofour business we also offer our own internally developed hosted services and cloud-based platform, software applications, and supporting products andservices. We are employing significant human and financial resources to develop and deploy these offerings. As we work to grow and scale these offerings,these investments have impacted our gross margins and profitability adversely in the past and may continue to do so in the future. While we believe we havea strong foundation to compete, it is uncertain whether our strategies will attract the users or generate the revenue required to be successful. We have and willencounter competition from other solutions providers, many of whom may have more significant resources than us with which to compete. Whether we aresuccessful in this business model depends on a number of factors, including:•our ability to put in place the infrastructure to deploy and evolve our solutions effectively and continuously;•the features and functionality of our offerings relative to competing offerings as well as our ability to market effectively;•our ability to engage in successful strategic relationships with third parties such as telecommunications carriers, component makers and systemsintegrators;•competing effectively for market share; and•deploying complete end-to-end solutions that meet the needs of the marketplace generally as well as the particular requirements of our customers moreeffectively and efficiently than competitive solutions.Our ability to sustain and grow our business depends in large part on the success of our channel partner distributors and resellers.A substantial part of our revenue is generated through sales by channel partner distributors and resellers. Sales through our channel partners accounted for61.5%, 66.1% and 61.8% of our total revenue in fiscal 2017, 2016 and 2015, respectively. Further, in recent years we have been taking steps to expand ourrelationship with certain distributors who have global reach, an effort that may increase the percent of our revenue driven through channel partners or ourreliance on certain channel partners to drive sales. To the extent our channel partners are unsuccessful in selling our products or if we are unable to obtain andretain a sufficient number of high-quality channel partners, our operating results could be materially and adversely affected. In addition, our channel partnersmay also market, sell and support products and services that are competitive with ours, and may devote more resources to the marketing, sales and support ofsuch products. They also may have incentives to promote our competitors’ products in lieu of our products, particularly for our competitors with largervolumes of orders, more diverse product offerings and a longer relationship with our distributors and resellers. In these cases, one or more of our importantchannel partners may stop selling our products completely. Our channel partner sales structure also could subject us to lawsuits, potential liability andreputational harm if, for example, any of our channel partners misrepresents the functionality of our products or services to customers, or violates laws or ourcorporate policies. If we fail to manage our existing or future sales channel partners effectively, our business and operating results could be materially andadversely affected.9Table of ContentsOur gross margins may be subject to decline.Our gross margins may be subject to decline which could decrease our overall profitability and impact our financial performance adversely. Many of thehardware products we sell are approaching the end of their product life cycles. These mature hardware products typically sell at higher gross margins than ourother product and service offerings. In fiscal 2017, sales of mature hardware products represented about 35.7% of our overall revenue. While these productsexperienced decreased year over year sales in excess of 20% in fiscal 2017, in general, revenues from the sale of these mature hardware products have beendeclining for several years at a rate of between 1% and 10%. We expect this trend to continue and it is uncertain whether fiscal 2017 represented an ongoingacceleration in the decline of these products. In addition, ongoing cost pressures in our industry create downward pressure on the prices at which we and othermanufacturers can sell hardware products. We also have indicated that we would be willing to realize lower levels of gross margins from customers in returnfor long-term, binding purchase commitments, a strategy that, if successful, could also put downward pressure on our gross margins. While part of our longerterm strategy is to sell software applications and IoT solutions such as Digi Smart Solutions™ which can provide recurring revenues at relatively high grossmargin, these types of offerings are at early stages of adoption by customers and their sales growth is not necessarily predictable or assured. As such, our grossmargins may be subject to decline unless we can implement cost reduction initiatives effectively to offset the impact of these factors.Our revenue may be subject to fluctuations based on the level of significant one time purchases.No single customer has represented more than 10% of our revenue in any of the last three fiscal years. However, many of our customers make significant one-time hardware purchases for large projects that are not repeated. As a result, our revenue may be subject to significant fluctuations based on whether we areable to close significant sales opportunities. Our failure to complete one or a series of significant sales opportunities in a particular fiscal period could have amaterial adverse effect on our revenue for that period.Certain of our products are sold into mature markets, which could limit our ability to continue to generate revenue from these products.Many of our hardware products are sold into mature markets that are characterized by a trend of declining demand. As the overall market for these maturehardware products decreases due to the adoption of new technologies, we expect that our revenue from these products will continue to decline. As a result,our future prospects depend in part on our ability to acquire or develop and successfully market additional products that address growth markets.Our ability to grow our business is dependent in part on strategic relationships we develop and maintain with third parties as well as our ability tointegrate and assure use of our products and services in coordination with the products and services of certain strategic partners in a commerciallyacceptable manner.We believe that our ability to increase our sales depends in part on maintaining and strengthening relationships with parties such as telecommunicationscarriers, systems integrators, enterprise application providers, component providers and other strategic technology companies. Once a relationship isestablished, we likely will dedicate significant time and resources to it in an effort to advance our business interests and there is no assurance any strategicrelationship will generate enough revenue to offset the significant resources we use to advance the relationship. Parties with whom we establish strategicrelationships may also work with companies that compete with us. We also have limited, if any, control as to whether these parties devote adequate resourcesto promoting, selling, and implementing our products. Further, new or emerging technologies, technological trends or changes in customer requirements mayresult in certain companies with whom we maintain strategic relationships de-emphasizing their dealings with us or becoming potential competitors in thefuture. We also have limited, if any, control as to other business activities of these parties and we could experience reputational harm because of ourassociation with such parties if they fail to execute on business initiatives, are accused of breaking the law or otherwise suffer reputational harm for otherreasons. All of these factors could materially and adversely impact our business and results of operations.In some cases we expect the establishment of a strategic relationship with a third party to result in integrations of our products or services with those of otherparties. Identifying appropriate parties for these relationships as well as negotiating and documenting business agreements with them requires significanttime and resources. We expect these agreements typically to be non-exclusive and not to prohibit the other party from working with our competitors oroffering competing services. Once the relationship is established we may also encounter difficulties in combining our products and services in acommercially acceptable manner. We expect this type of dynamic, whereby our ability to realize sales opportunities is dependent on how our products andservices interact with those sold by third parties, may become more common as the marketplace in our industry evolves. There can be no guarantee in anyparticular instance that we will be successful in making our products interact with those of other parties in a commercially acceptable manner and, even if wedo, we cannot guaranty the resulting products and services will be marketed or sold effectively via the relationship.10Table of ContentsOur failure to compete successfully in our highly competitive market could result in reduced prices and loss of market share.The market in which we operate is characterized by rapid technological advances and evolving industry standards. The market can be affected significantlyby new product introductions and marketing activities of industry participants. In addition, the amount of competition we face in the marketplace maychange and grow as the market for our industry grows and new entrants enter the marketplace. Present and future competitors may be able to identify newmarkets and develop products more quickly, which are superior to those developed by us. They may also adapt new technologies faster, devote greaterresources to research and development, promote products more aggressively, and price products more competitively than us. Competition may also intensifyor we may no longer be able to compete effectively in the markets in which we compete.Our failure to anticipate or manage product transitions effectively could have a material adverse effect on our revenue and profitability.From time to time, we or our competitors may announce new products, capabilities, or technologies that may replace or shorten the life cycles of our existingproducts. Announcements of currently planned or other new products may cause customers to defer or stop purchasing our products until new productsbecome available. Furthermore, the introduction of new or enhanced products requires us to manage the transition from older product inventories and ensurethat adequate supplies of new products can be delivered to meet customer demand. Our failure to anticipate the revenue declines associated with olderproducts or manage transitions from older products effectively could result in inventory obsolescence and also have a material adverse effect on our revenueand profitability.Acquisitions could disrupt our business and seriously harm our financial condition.We will continue to consider acquisitions of complementary businesses, products or technologies. In the event of any future acquisitions, we could issuestock that would dilute our current stockholders’ percentage ownership, incur debt, assume liabilities, or incur large and immediate write-offs.Our operation of any acquired business also involves numerous risks, including but not limited to:•problems combining the purchased operations, technologies, or products;•unanticipated costs;•diversion of management’s attention from our core business;•difficulties integrating businesses in different countries and cultures;•adverse effects on existing business relationships with suppliers and customers;•risks associated with entering markets in which we have no or limited prior experience; and•potential loss of key employees, particularly those of the purchased organization.We cannot assure that we will be able to successfully integrate any businesses, products, technologies, or personnel that we have acquired or that we mightacquire in the future and any failure to do so could disrupt our business and have a material adverse effect on our consolidated financial condition and resultsof operations. Moreover, from time to time, we may enter into negotiations for a proposed acquisition, but be unable or unwilling to consummate theacquisition under consideration. This could cause significant diversion of management’s attention and out-of-pocket expenses for us. We could also beexposed to litigation as a result of any consummated or unconsummated acquisition.We are subject to various cybersecurity risks, which are particularly acute in the cloud-based technologies operated by us and other third parties that forma part of our solutions. These risks may increase our costs and could damage our brand and reputation.As we continue to direct a substantial portion of our sales and development efforts toward broader based solutions, such as Digi Smart Solutions™ and theDigi Remote Manager®, we expect to store, convey and potentially process significant amounts of data produced by devices. This data may includeconfidential or proprietary information, intellectual property or personally identifiable information of our customers or other third parties with whom they dobusiness. It is important for us to maintain solutions and related infrastructure that are perceived by our customers and other parties with whom we dobusiness to provide a reasonable level of reliability and security. Despite available security measures and other precautions, the infrastructure andtransmission methods used by our products and services may be vulnerable to interception, attack or other disruptive problems.11Table of ContentsContinued high-profile data breaches at other companies evidence an external environment that is becoming increasingly hostile to information security.Improper disclosure of data or perception that our data security is insufficient could harm our reputation, give rise to legal proceedings, or subject ourcompany to liability under laws that protect data, any of which could result in increased costs and loss of revenue.If a cyberattack or other security incident were to allow unauthorized access to or modification of our customers’ data or our own data, whether due to afailure with our systems or related systems operated by third parties, we could suffer damage to our brand and reputation. The costs we would incur to addressand fix these incidents could significantly increase our expenses. These types of security incidents could also lead to lawsuits, regulatory investigations andincreased legal liability, including in some cases contractual costs related to customer notification and fraud monitoring. Further, as regulatory focus onprivacy and data security issues continues to increase and worldwide laws and regulations concerning the protection of information become more complex,the potential risks and costs of compliance to our business will intensify.Digi Smart Solutions™ is a new business line for us and is subject to the risks faced by a new business.Digi Smart Solutions™ was formed through acquisitions of various businesses and represents a new business line for our company. Our management haslimited experience in this marketplace. The operation of Digi Smart Solutions™ will be subject to significant additional risks that are not necessarily relatedto our legacy products and services.Additional risks that relate to Digi Smart Solutions™, include, but are not limited to:•We have not traditionally sold products or services to restaurants, pharmacies, hospitals and other similar businesses, which are a focus for Digi SmartSolutions™.•Digi Smart Solutions™ offerings are deployed in part to help assure perishable goods are safely preserved. This presents a risk of loss in the event of amalfunction or failure of our offerings.•Although we have retained several key employees with extensive experience in operating companies we have acquired to date, Digi Smart Solutions™represents a new line of business in a marketplace that is nascent in its development and has numerous competitors. We cannot provide assurances wewill be successful in operating and growing this business.•Our ability to succeed with the Digi Smart Solutions™ offerings will depend in large part on our ability to provide customers with hardware and softwareproducts that are easy to deploy and offer features and functionality that address the needs of particular businesses. We may face challenges and delays inthe development of this business as the marketplace for products and services evolves to meet the needs and desires of customers.In light of these risks and uncertainties, we may not be able to establish or maintain Digi Smart Solutions™’ market share, integrate it successfully into ourother operations or take full advantage of businesses we have acquired or may acquire in the future. There can be no assurance that we will recover ourinvestments in this new business, that we will realize a profit from this new business or that diverting our management’s attention to this new business willnot have a material adverse effect on our existing businesses, any of which may have a material adverse effect on our results of operations, financial conditionand prospects.Our consolidated operating results and financial condition may be adversely impacted by worldwide economic conditions and credit tightening.If worldwide economic conditions experience a significant downturn, these conditions may make it difficult or impossible for our customers and suppliers toaccurately forecast and plan future business activities, which may cause them to slow or suspend spending on products and services. Our customers may findit difficult to gain sufficient credit in a timely manner, which could result in an impairment of their ability to place orders with us or to make timely paymentsto us for previous purchases. If this occurs, our revenue may be reduced, thereby having a negative impact on our results of operations. In addition, we may beforced to increase our allowance for doubtful accounts and our days sales outstanding may increase, which would have a negative impact on our cashposition, liquidity and financial condition. We cannot predict either the timing or duration of an economic downturn in the economy, should one occur.The long and variable sales cycle for certain of our products makes it more difficult for us to predict our operating results and manage our business.The sale of our products and services can involve a significant technical evaluation and commitment of capital and other resources by potential customersand end users, as well as delays frequently associated with end users’ internal procedures to deploy new technologies within their products and to test andaccept new technologies. For these and other reasons, the sales12Table of Contentscycle associated with certain of our products is typically lengthy and is subject to a number of significant risks, such as end users’ internal purchasingreviews, that are beyond our control. Because of the lengthy sales cycle and the large size of certain customer orders, if orders forecasted for a specificcustomer are not realized or delayed, our operating results could be materially adversely affected.We depend on manufacturing relationships and on limited-source suppliers, and any disruptions in these relationships may cause damage to our customerrelationships.We procure all parts and certain services involved in the production of our products and subcontract most of our product manufacturing to outside firms thatspecialize in such services. Although most of the components of our products are available from multiple vendors, we have several single-source supplierrelationships, either because alternative sources are not available or because the relationship is advantageous to us. There can be no assurance that oursuppliers will be able to meet our future requirements for products and components in a timely fashion. In addition, the availability of many of thesecomponents to us is dependent in part on our ability to provide our suppliers with accurate forecasts of our future requirements. Delays or lost revenue couldbe caused by other factors beyond our control, including late deliveries by vendors of components, or force majeure events. For instance, a fire in November2014 disrupted the operations at one of our contract manufacturers in Thailand. If we are required to identify alternative suppliers for any of our requiredcomponents, qualification and pre-production periods could be lengthy and may cause an increase in component costs and delays in providing products tocustomers. Any extended interruption in the supply of any of the key components currently obtained from limited sources could disrupt our operations andhave a material adverse effect on our customer relationships and profitability.Our inability to obtain the appropriate telecommunications carrier certifications or approvals from governmental regulatory bodies could impede ourability to grow revenue in our wireless products.The sale of our wireless products in certain geographical markets is sometimes dependent on the ability to gain telecommunications carrier certificationsand/or approvals by certain governmental bodies. Failure to obtain these approvals, or delays in receiving the approvals, could impact our ability to enter ourtargeted markets or to compete effectively or at all in these markets and could have an adverse impact on our revenue.We are dependent on wireless communication networks owned and controlled by others.Our revenue could decline if we are unable to deliver continued access to digital cellular wireless carriers that we depend on to provide sufficient networkcapacity, reliability and security to our customers. Our financial condition could be impacted if our wireless carriers were to increase the prices of theirservices, or to suffer operational or technical failures.The impact of natural disasters could negatively impact our supply chain and customers resulting in an adverse impact to our revenue and profitability.Certain of our components and other materials used in producing our products are from regions susceptible to natural disasters. If we are unable to procurenecessary materials, we could experience a disruption to our supply chain that would hinder our ability to produce our products in a timely manner, or causeus to seek other sources of supply, which may be more costly or which we may not be able to procure on a timely basis. We also risk damage to any tooling,equipment or inventory at the supplier’s facilities. For instance, flooding in October 2011 and a fire in November 2014 disrupted the operations at one of ourcontract manufacturers in Thailand. In addition, our customers may not follow their normal purchasing patterns or temporarily cease purchasing from us dueto impacts to their businesses in the region, creating unexpected fluctuations or decreases in our revenue and profitability. Natural disasters in other parts ofthe world on which our operations are reliant also could have material adverse impacts on our business.Our use of suppliers in other parts of the world involves risks that could negatively impact us.We purchase a number of components from suppliers in other parts of the world. Product delivery times may be extended due to the distances involved,requiring more lead time in ordering. In addition, ocean freight delays may occur as a result of labor problems, weather delays or expediting and customsissues. Any extended delay in receipt of the component parts could eliminate anticipated cost savings and have a material adverse effect on our customerrelationships and profitability.Our ability to compete could be jeopardized if we are unable to protect our intellectual property rights.Our ability to compete depends in part on our proprietary rights and technology. Our proprietary rights and technology are protected by a combination ofcopyrights, patents, trade secrets and trademarks. We enter into confidentiality agreements with our employees, and sometimes with our customers, potentialcustomers and other third parties, and limit access to the distribution of our proprietary information. There can be no assurance that the steps taken by us inthis regard will be adequate13Table of Contentsto prevent the misappropriation of our technology. Our pending patent applications may be denied and any patents, once issued, may be circumvented byour competitors. Furthermore, there can be no assurance that others will not develop technologies that are superior to our technologies. Despite our efforts toprotect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or to obtain and use information that we regard as proprietary.In addition, the laws of some foreign countries do not protect our proprietary rights as fully as do the laws of the United States. There can be no assurance thatour means of protecting our proprietary rights in the United States or abroad will be adequate or that competing companies will not independently developsimilar technologies. Our failure to adequately protect our proprietary rights could have a material adverse effect on our competitive position and result inloss of revenue.From time to time, we are subject to claims and litigation regarding intellectual property rights or other claims, which could seriously harm us and requireus to incur significant costs.The communications technology industry is characterized by frequent litigation regarding patent and other intellectual property rights. From time to time, wereceive notification of a third-party claim that our products infringe other intellectual property rights. Any litigation to determine the validity of third-partyinfringement claims, whether or not determined in our favor or settled by us, may be costly and divert the efforts and attention of our management andtechnical personnel from productive tasks, which could have a material adverse effect on our ability to operate our business and service the needs of ourcustomers. There can be no assurance that any infringement claims by third parties, regardless if they have merit, will not materially adversely affect ourbusiness, operating results or financial condition. In the event of an adverse ruling in any such matter, we may be required to pay substantial damages, ceasethe manufacture, use and sale of infringing products, discontinue the use of certain processes or be required to obtain a license under the intellectual propertyrights of the third party claiming infringement. There can be no assurance that a license would be available on reasonable terms or at all. Any limitations onour ability to market our products, or delays and costs associated with redesigning our products or payments of license fees to third parties, or any failure byus to develop or license a substitute technology on commercially reasonable terms could have a material adverse effect on our business, operating results andfinancial condition.We face risks associated with our international operations and expansion that could impair our ability to grow our revenue abroad as well as our overallfinancial condition.We believe that our future growth is dependent in part upon our ability to increase sales in international markets. These sales are subject to a variety of risks,including fluctuations in currency exchange rates, tariffs, import restrictions and other trade barriers, unexpected changes in regulatory requirements, longeraccounts receivable payment cycles, potentially adverse tax consequences, and export license requirements. In addition, we are subject to the risks inherentin conducting business internationally, including political and economic instability and unexpected changes in diplomatic and trade relationships. In manymarkets where we operate business and cultural norms are different than those in the United States and practices that may violate laws and regulationsapplicable to us like the Foreign Corrupt Practices Act (FCPA) and the UK Anti-Bribery Act (UKBA) are more commonplace. Although we have implementedpolicies and procedures with the intention of ensuring compliance with these laws and regulations, our employees, contractors and agents, as well as channelpartners involved in our international sales, may take actions in violation of our policies. Many of our vendors and strategic business allies also haveinternational operations and are subject to the risks described above. Even if we are able to successfully manage the risks of international operations, ourbusiness may be adversely affected if one or more of our business partners are not able to successfully manage these risks. There can be no assurance that oneor more of these factors will not have a material adverse effect on our business strategy and financial condition.Our failure to comply effectively with regulatory laws pertaining to our foreign operations could have a material adverse effect on our revenue andprofitability.We are required to comply with U.S. government export regulations in the sale of our products to foreign customers, including requirements to properlyclassify and screen our products against a denied parties list prior to shipment. We are also required to comply with the provisions of the FCPA and all otheranti-corruption laws, such as UKBA, of all other countries in which we do business, directly or indirectly, including compliance with the anti-briberyprohibitions and the accounting and recordkeeping requirements of this law. Violations of the FCPA or other similar laws could trigger sanctions, includingineligibility for U.S. government insurance and financing, as well as large fines. Failure to comply with the aforementioned regulations could also deter usfrom selling our products in international jurisdictions, which could have a material adverse effect on our revenue and profitability.Foreign currency exchange rates may adversely affect our operating results.We are exposed to a variety of market risks, including the effects of changes in foreign currency exchange rates on transactions that are denominated inforeign currencies. Because our financial statements are denominated in U.S. Dollars and14Table of Contentsapproximately 11% of our revenue is denominated in a currency other than U.S. Dollars, such as Euros, British Pounds, Yen and Canadian Dollars, ourrevenues and earnings may be adversely impacted if the U.S. dollar strengthens significantly against these foreign currencies.The loss of key personnel could prevent us from executing our business strategy.Our business and prospects depend to a significant degree upon the continuing contributions of our executive officers and key technical and other personnel.Competition for such personnel is intense, and there can be no assurance that we will be successful in attracting and retaining qualified personnel. Failure toattract and retain key personnel could result in our failure to execute our business strategy.Our failure to comply effectively with the requirements of applicable environmental legislation and regulation could have a material adverse effect on ourrevenue and profitability.Production and marketing of products in certain states and countries may subject us to environmental and other regulations. In addition, certain states andcountries may pass new regulations requiring our products to meet certain requirements to use environmentally friendly components. The European Unionhas issued two directives relating to chemical substances in electronic products. The Waste Electrical and Electronic Equipment Directive (WEEE) makesproducers of certain electrical and electronic equipment financially responsible for collection, reuse, recycling, treatment and disposal of equipment placedin the European Union market. The Restrictions of Hazardous Substances Directive (RoHS) bans the use of certain hazardous materials in electric andelectrical equipment which are put on the market in the European Union. In the future, China and other countries including the United States may adoptfurther environmental compliance programs. If we fail to comply with these regulations, we may not be able to sell our products in jurisdictions where theseregulations apply, which could have a material adverse effect on our revenue and profitability.Negative conditions in the global credit markets may impair a portion of our investment portfolio.Our investment portfolio consists of certificates of deposit, commercial paper, money market funds, corporate bonds and government municipal bonds. Thesemarketable securities are classified as available-for-sale and are carried at fair market value. Some of our investments could experience reduced liquidity andcould result in an impairment charge should the impairment be considered as other-than-temporary. This loss would be recorded in our consolidatedstatement of operations, which could materially adversely impact our consolidated results of operations and financial condition.Unanticipated changes in our tax rates could affect our future results.Our future effective tax rates could be favorably or unfavorably affected by unanticipated changes in the mix of earnings in countries with differing statutorytax rates, changes in the valuation of our deferred tax assets and liabilities, or by changes in tax laws or our interpretation of such laws. In addition, we may besubject to the examination of our income tax returns by the Internal Revenue Service and other U.S. and international tax authorities. We regularly assess thepotential outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. There can be no assurance that theoutcomes from these examinations will not have an adverse effect on our consolidated operating results and financial condition.We may have additional tax liabilities.We are subject to income taxes in the United States and many foreign jurisdictions. Significant judgment is required in determining our worldwide provisionfor income taxes, including our reserves for uncertain tax positions. In the ordinary course of business, there are many transactions and calculations where theultimate tax determination is uncertain. We regularly are under audit by tax authorities. Although we believe our tax estimates are reasonable, the finaldetermination of tax audits could be materially different from our historical income tax provisions and accruals. The results of an audit could have a materialeffect on our consolidated financial position, results of operations, or cash flows in the period or periods for which that determination is made.Risks Related to Our Common StockUnsolicited takeover proposals, governance change proposals, proxy contests and resulting litigation may adversely impact our operations, createuncertainty and affect the market price and volatility of our securities.In fiscal 2017, we received an unsolicited takeover proposal and other companies in our industry have been the target of unsolicited takeover proposals inthe past. In the event that a third party, such as a competitor, private equity firm or activist investor makes an unsolicited takeover proposal, or proposes tochange our governance policies or board of directors, or makes15Table of Contentsother proposals concerning our ownership structure or operations, our review and consideration of such proposals may be a significant distraction for ourmanagement and employees, and could require us to expend significant time and resources. Such proposals may create uncertainty for our employees and thisuncertainty may adversely affect our ability to retain key employees, to hire new talent or to complete acquisitions we may desire to make. Similaruncertainty among our customers, suppliers and other business partners could cause them to terminate, or not to renew or enter into, arrangements with us.Certain proposals may result in costly proxy contests or litigation that can disrupt our business operations or result in an adverse effect on our operatingresults. Management and employee distraction related to any such proposals also may adversely impact our ability to conduct our business optimally andpursue our strategic objectives. Such proposals, or their withdrawal, could create uncertainty among investors and potential investors as to our futuredirection and affect the market price of our common stock without regard to our operational or financial performance.Certain provisions of the Delaware General Corporation Law and our charter documents have an anti-takeover effect.There exist certain mechanisms under the Delaware General Corporation Law and our charter documents that may delay, defer or prevent a change of control.For instance, under Delaware law, we are prohibited from engaging in certain business combinations with interested stockholders for a period of three yearsafter the date of the transaction in which the person became an interested stockholder unless certain requirements are met, and majority stockholder approvalis required for certain business combination transactions with interested parties.Our Certificate of Incorporation contains a "fair price" provision requiring majority stockholder approval for certain business combination transactions withinterested parties, and this provision may not be changed without the vote of at least 80% of the outstanding shares of our voting stock. Other mechanisms inour charter documents may also delay, defer or prevent a change of control. For instance, our Certificate of Incorporation provides that our Board of Directorshas authority to issue series of our preferred stock with such voting rights and other powers as the Board of Directors may determine. Furthermore, we have aclassified board of directors, which means that our directors are divided into three classes that are elected to three-year terms on a staggered basis. Since thethree-year terms of each class overlap the terms of the other classes of directors, the entire board of directors cannot be replaced in any one year. UnderDelaware law, directors serving on a classified board may not be removed by shareholders except for cause. Also, pursuant to the terms of our shareholderrights plan, each outstanding share of common stock has one attached right. The rights will cause substantial dilution of the ownership of a person or groupthat attempts to acquire us on terms not approved by the Board of Directors and may have the effect of deterring hostile takeover attempts. The effect of theseanti-takeover provisions may deter business combination transactions not approved by our Board of Directors, including acquisitions that may offer apremium over the market price to some or all stockholders.The price of our common stock has been volatile and could continue to fluctuate in the future.The market price of our common stock, like that of many other high-technology companies, has fluctuated significantly and is likely to continue to fluctuatein the future. During fiscal 2017, the closing price of our common stock on the NASDAQ Global Select Market ranged from $8.60 to $14.10 per share. Ourclosing sale price on November 20, 2017 was $10.15 per share. Announcements by us or others regarding the receipt of customer orders, quarterly variationsin operating results, departures of key personnel, acquisitions or divestitures, additional equity or debt financings, results of customer field trials, scientificdiscoveries, technological innovations, litigation, product developments, patent or proprietary rights, government regulation and general market conditionsand risks may, for example, have a significant impact on the market price of our common stock.If our stock price declines over a sustained period of time or our profits significantly decrease, we may need to recognize an impairment of our goodwill.The price of our common stock could decline. If such a decline continued over a sustained period of time, we could have an impairment of our goodwill. Ourmarket value is dependent upon certain factors, including continued future growth of our products and solutions. If such growth does not materialize or ourforecasts are not met, our profits could be significantly reduced and our market value may decline, which could result in an impairment of our goodwill.Goodwill is tested for impairment on an annual basis as of June 30, or more frequently if events or circumstances occur which could indicate impairment.ITEM 1B.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSOur management’s discussion and analysis should be read in conjunction with our consolidated financial statements and other information in this AnnualReport on Form 10-K for the fiscal year ended September 30, 2017.FORWARD-LOOKING STATEMENTSThis Annual Report contains certain statements that are "forward-looking statements" as that term is defined under the Private Securities Litigation ReformAct of 1995, and within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, asamended.Words such as "assume," "believe," "anticipate," "intend," "estimate," "target," "may," "will," "expect," "plan," "project," "should," or "continue" or thenegative thereof or other expressions, which are predictions of or indicate future events and trends and which do not relate to historical matters, identifyforward-looking statements. Among other items, these statements relate to expectations of the business environment in which the company operates,projections of future performance, perceived marketplace opportunities and statements regarding our mission and vision. Such statements are not guaranteesof future performance and involve certain risks, uncertainties and assumptions, including risks related to the highly competitive market in which ourcompany operates, rapid changes in technologies that may displace products sold by us, declining demand for and prices of networking products, ourreliance on distributors and other third parties to sell our products, delays in product development efforts, uncertainty in user acceptance of our products, theability to integrate our products and services with those of other parties in a commercially accepted manner, potential liabilities that can arise if any of ourproducts have design or manufacturing defects, our ability to defend or settle satisfactorily any litigation, uncertainty in global economic conditions andeconomic conditions within particular regions of the world which could negatively affect product demand and the financial solvency of customers andsuppliers, the impact of natural disasters and other events beyond our control that could negatively impact our supply chain and customers, potentialunintended consequences associated with restructuring or other similar business initiatives that may impact our ability to retain important employees, theability to achieve the anticipated benefits and synergies associated with acquisitions or divestitures, and changes in our level of revenue or profitabilitywhich can fluctuate for many reasons beyond our control.These and other risks, uncertainties and assumptions identified from time to time in our filings with the United States Securities and Exchange Commission,including without limitation, those described in Item 1A, Risk Factors, of this Form 10-K and subsequent quarterly reports of Form 10-Q and other filings,could cause our future results to differ materially from those expressed in any forward-looking statements made by us or on our behalf. Many of such factorsare beyond our ability to control or predict. These forward-looking statements speak only as of the date for which they are made. We disclaim any intent orobligation to update any forward-looking statements, whether as a result of new information, future events or otherwise.PRESENTATION OF NON-GAAP FINANCIAL MEASURESThis report includes EBITDA from continuing operations, which is a non-GAAP financial measure. Non-GAAP financial measures are not substitutes forGAAP financial measures, such as net income, for the purpose of analyzing financial performance. The disclosure of these measures does not reflect allcharges and gains that were actually recognized by the company. Non-GAAP financial measures are not prepared in accordance with, or an alternative formeasures prepared in accordance with, generally accepted accounting principles and may be different from non-GAAP financial measures used by othercompanies. In addition, non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles. We believe that non-GAAPfinancial measures have limitations in that they do not reflect all of the amounts associated with our results of operations as determined in accordance withGAAP and that these measures should only be used to evaluate our results of operations in conjunction with the corresponding GAAP financial measures.Additionally, we understand that EBITDA from continuing operations does not reflect our cash expenditures, the cash requirements for the replacement ofdepreciated and amortized assets, or changes in or cash requirements for our working capital needs.We believe that the presentation of EBITDA from continuing operations as a percentage of revenue is useful because it provides a reliable and consistentapproach to measuring our performance from year to year and in assessing our performance against that of other companies. We believe this information helpscompare operating results and corporate performance exclusive of the impact of our capital structure and the method by which assets were acquired. EBITDAfrom continuing operations is used as an internal metric for executive compensation, as well as incentive compensation for the rest of the employee base, andit is monitored quarterly for these purposes.21Table of ContentsITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)OVERVIEWWe are a leading global provider of business and mission-critical machine-to-machine (M2M) and Internet-of-Things (IoT) connectivity products andservices. As of the fiscal quarter ended June 30, 2017, we determined that we have two reportable operating segments for purposes of ASC 280-10-50"Segments Reporting":•M2M segment; and•Solutions segment.Our M2M segment consists primarily of distinct communications products and communication product development services. Among other things, theseproducts and services help our customers create next generation connected products and deploy and manage critical communications infrastructures indemanding environments with high levels of security and reliability. We create secure, easy to implement embedded solutions and services to help customersbuild IoT connectivity. We also deploy ready to use, complete box solutions to connect remote machinery. We also offer dedicated professional services forthe design of specialized wireless communications products for customers. Finally, through this segment we offer managed cloud services that enablecustomers to capture and manage data from devices they connect to networks. The products and services of this segment are used by a wide range ofbusinesses and institutions.All of the revenue we report in our consolidated financial statements as hardware product revenue is derived from products included in this segment. Theseproducts include our cellular routers and gateways, radio frequency (RF), embedded and network products. Our cellular product category includes ourcellular routers and gateways. Our RF product category includes our XBee® modules as well as other RF Solutions. Our Embedded product category includesDigi Connect® and Rabbit® embedded systems on module and single board computers. Our network product category, which has the highest concentrationof mature products, includes console and serial servers and USB connected products. Revenues we report as services and solutions revenue in ourconsolidated financial statements from this segment include Digi Wireless Design Services, Digi Remote Manager® and support services we provide for ourhardware products.Our Solutions segment offers wireless temperature and other environmental condition monitoring services as well as employee task management services.These products and services are provided to food service, transportation, education, healthcare and pharma, and industrial markets and are marketed as DigiSmart Solutions™. We have formed the Solutions segment primarily through a series of acquisitions including the October 2015 acquisition of BluenicaCorporation (Bluenica), the November 2016 acquisition of FreshTemp, LLC (FreshTemp) and the January 2017 acquisition of SMART Temps, LLC (SMARTTemps) to enhance and expand the capabilities of the Solutions segment. All revenues from this segment are reported in our consolidated financial statementsas services and solutions revenue as customers subscribe for ongoing monitoring services that are enabled by the deployment of hardware and relatedsoftware. For further detail on segment performance, see Segment Results of Operations section of the management discussion and analysis.We utilize many financial, operational, and other metrics to evaluate our financial condition and financial performance. Below we highlight the fiscal 2017metrics that we feel are most important in these evaluations:•Revenue was $181.6 Million. Our revenue decreased by $21.4 million, or 10.5%, compared to fiscal 2016. This decrease was due to a decrease inproduct revenue of $29.6 million, offset by an increase in services and solutions revenue of $8.2 million.•Gross Margin was 48.0%. Our gross margin decreased as a percentage of revenue to 48.0% in fiscal 2017 from 49.1% in fiscal 2016. Hardwareproduct gross margin, excluding amortization, was 48.7% in fiscal 2017, compared to 50.1% in the prior fiscal year. Service gross margin, excludingamortization, for fiscal 2017 was 49.5% compared to 32.5% in the prior fiscal year.•Income from Continuing Operations was $9.4 Million and Earnings Per Diluted Share from Continuing Operations were $0.35. Our income fromcontinuing operations decreased by $4.1 million, or 30.5%, compared to fiscal 2016. Earnings per diluted share from continuing operations were$0.35 in fiscal 2017, compared to $0.51 in fiscal 2016. The decline in income from continuing operations due primarily to a decline in gross profitof $12.5 million driven by a decline in the network product category, which includes traditionally higher margin products compared to our otherproducts, partially offset by an increase in services and solutions gross profit. This was partially offset by a decrease in operating expenses of $4.2million, primarily due to lower incentive-based compensation expense, and benefits due to adjustments to our contingent consideration liabilityaccruals, offset by incremental expenses related to the SMART22Table of ContentsITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)Temps acquisition, merger and acquisition costs and restructuring charges.•Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) from Continuing Operations was $14.4 Million. Our EBITDA fromcontinuing operations was $14.4 million, or 7.9% of revenue, in fiscal 2017, compared to $21.0 million, or 10.4% of revenue, in fiscal 2016.

Our current ratio was 9.7 to 1 at September 30, 2017, compared to 8.2 to 1 at September 30, 2016.We accomplished a number of key initiatives in fiscal 2017 and also face challenges relative to our business.Accomplishments•Our service and solutions revenue increased 119.5% during fiscal 2017 compared to fiscal 2016. The increase was primarily driven by the growth ofour Digi Smart Solutions™ business. Services and solutions revenue includes $6.1 million of incremental revenue from the acquisition of SMARTTemps and FreshTemp in fiscal 2017. We also had increases to our Digi Wireless Design Services, Digi Remote Manager® platform and supportservices.•Our total cash and cash equivalents and marketable securities including long-term marketable securities, amounted to $115.0 million at September30, 2017, a decrease of $22.7 million from September 30, 2016. We completed two acquisitions in fiscal 2017, for a total cash expenditure of $30.1million (net of cash acquired of $0.5 million).•During fiscal 2017, we have continued to reduce the number of product stock keeping units (SKUs) we produce, which we believe will havesignificant implications on our ability to manage inventory effectively, improve channel stocking strategies and control costs.•We continued to simplify and scale our business. We reduced the number of office locations by consolidating our France operations into our EMEAHeadquarters in Munich, Germany office and closed our France office location.•In October 2017, subsequent to the end of our fiscal year, we acquired TempAlert, LLC, a Boston-based provider of automated, real-time temperaturemonitoring and task management solutions. TempAlert will join Digi Smart Solutions™.Challenges•Our network products decreased by 26.0% in fiscal 2017 compared to fiscal 2016, which is a more rapid decline than expected. Demand for theseproducts has been declining for several years and we expect revenues for these products will continue to decline in the future at a rate ofapproximately 10% to 15% annually.•Our embedded products and RF products revenue declined of 15.0% and 14.6%, respectively, in fiscal 2017 as compared to fiscal 2016. The declinein both product categories is primarily due to significant sales to large customers in the prior fiscal year, which were not repeated.•Revenue for new product introductions in fiscal 2017 were not met.23Table of ContentsITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)•Revenue expectations for Digi Smart Solutions™ were not met. Although we found the sales cycles to be longer than expected, the segment still hasa growing pipeline.CONSOLIDATED RESULTS OF OPERATIONSThe following table sets forth selected information derived from our Consolidated Statements of Operations, expressed in dollars and as a percentage ofrevenue and as a percentage of change from year-to-year for the years indicated.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)2017 Compared to 2016Cellular routers and gateway product revenue decreased $1.3 million, or 2.6%, in fiscal 2017 as compared to fiscal 2016. These decreases primarily were dueto a decrease in our transport revenue. Cellular router and gateway revenue is substantially driven by large awards-based customer projects and is subject torevenue fluctuations from quarter to quarter, based on when the awarded projects are deployed.RF product revenue decreased $4.9 million, or 14.6%, in fiscal 2017 as compared to fiscal 2016 primarily due to larger sales to certain customers in the priorfiscal year in our Latin America and North America regions in fiscal 2016. RF products can fluctuate from period to period because of large customer projects.We are encouraged by the design wins and building pipeline for our new cellular XBee, first released in March 2017. We are continuing to design additionalfeatures and functionality into this product. The product is an embedded module that speeds product introduction and lowers development and certificationcosts for our customers. We anticipate design wins to begin converting to revenues when production volumes contribute in fiscal 2018.Embedded product revenue decreased by $8.5 million, or 15.0%, in fiscal 2017 as compared to fiscal 2016 particularly in the North American and EMEAregions, as there were significant customers moving their products to production in the prior fiscal year. We expect mature products, like Rabbit®, to faceongoing challenges. In April 2017, we released our new ConnectCore 6UL product. The ConnectCore 6UL is a power efficient, low cost and small industrialSystem-on-Module (SOM). We are encouraged by the design wins and building pipeline and expect this product to begin converting to revenues whenproduction volumes contribute in fiscal 2018.Network product revenue decreased $14.9 million, or 26.0%, in fiscal 2017 as compared to fiscal 2016. The decrease was mostly due to a decrease in sales ofterminal servers as we had significant sales to a large customer that bought numerous products in fiscal 2016. We also experienced a decline in device servers,partially offset by an increase in USB connected products. As we discussed in the past, because these products are in the mature portion of their product lifecycle, this category is generally down. Absent the significant decline from another large customer, we expect that network product revenue will decline in thefuture at a rate of approximately 10% to 15% annually.2016 Compared to 2015Cellular routers and gateways product revenue decreased $10.3 million, or 17.5%, in fiscal 2016 as compared to fiscal 2015. This decrease primarily was dueto lower purchases by significant customers, across all regions. In addition, there were delays of certain product introductions. Cellular router and gatewayrevenue is substantially driven by large awards-based customer projects and is subject to revenue fluctuations from quarter to quarter, based on when theawarded projects are deployed.RF product revenue decreased $0.5 million, or 1.3%, in fiscal 2016 as compared to the prior fiscal year due to slower sales to energy-related customers.Embedded product revenue increased $5.5 million, or 10.6%, in fiscal 2016 as compared to fiscal 2015 as significant customers moved new initiatives toproduction in the North America and EMEA regions.Network product revenue increased $5.9 million, or 11.5%, in fiscal 2016 as compared to fiscal 2015 primarily related to large terminal server sales tosignificant customers. Most of our network products are in the mature phase of their product life cycle.Services and Solutions2017 Compared to 2016Services and solutions revenue for fiscal 2017 was $15.2 million compared to $6.9 in the prior fiscal year, an increase of $8.3 million, or 119.5%. Theincrease was primarily driven by the growth of our Digi Smart Solutions™ business. Services and solutions revenue includes $6.1 million of incrementalrevenue from the acquisitions of SMART Temps and FreshTemp in fiscal 2017. We acquired SMART Temps on January 9, 2017 and FreshTemp onNovember 1, 2016. In addition, Digi Wireless Design Services revenue increased $0.9 million. Revenue with our Digi Smart Solutions™ group increased$0.6 million. Revenue from the Digi Remote Manager® platform and support services increased by $0.6 million. We expect that revenue from Digi SmartSolutions™ group will continue to increase as we focus on expanding this business, which includes a component of recurring revenue. In October 2017,subsequent to the end of our fiscal year, we acquired TempAlert, LLC, which is part of Digi Smart Solutions™.25Table of ContentsITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)2016 Compared to 2015Service revenue for fiscal 2016 was $6.9 million compared to $8.3 in the prior fiscal year, a decrease of $1.4 million, or 17.3%. The decrease was primarilydue to a $1.5 million decline in revenue for our Digi Wireless Design Services as we struggled to generate sufficient demand while we were transitioning thisbusiness to our World Headquarters location as well as identifying new senior leadership. Revenue from the Digi Remote Manager® platform and supportservices decreased by $0.6 million. We received incremental revenue from Digi Smart Solutions™ of $0.7 million which was acquired during the first quarterof fiscal 2016.Revenue by Geographic LocationOur revenue by geographic location of our customers was as follows: Revenue % of Revenue($ in millions) 2017 2016 2015 2017 2016 2015North America, primarily United States $117.7 $131.5 $127.6 64.8% 64.8% 62.6%Europe, Middle East & Africa 39.4 44.9 47.5 21.7% 22.1% 23.3%Asia 19.9 20.4 22.9 11.0% 10.0% 11.2%Latin America 4.6 6.2 5.8 2.5% 3.1% 2.9%Total revenue $181.6 $203.0 $203.8 100.0% 100.0% 100.0%2017 Compared to 2016North America revenue in fiscal 2017 decreased $13.8 million, or 10.4%, compared to fiscal 2016, primarily related to a decrease in sales of terminal serversas we had significant sales to a large customer that bought numerous products in fiscal 2016. In addition, sales of Rabbit® modules decreased. We expectmature products, like Rabbit, to face ongoing challenges. This was partially offset by an increase of $6.7 million related to Digi Smart Solutions™ group,which included $6.1 of incremental revenue from the acquisitions of SMART Temps and FreshTemp in fiscal 2017.EMEA revenue decreased $5.5 million, or 12.3%, in fiscal 2017 as compared to fiscal 2016. The decrease primarily was due to a decrease of product revenuefrom embedded modules, terminal servers and cellular gateway products. In addition, we experienced fluctuations of foreign currency rates, which had anunfavorable impact on total revenue of $0.4 million for fiscal 2017 as compared to fiscal 2016 due to the weakening of the Euro and British Pound comparedto the U.S. Dollar.Asian countries revenue decreased $0.5 million, or 2.4%, in fiscal 2017 as compared to fiscal 2016.Latin America revenue decreased $1.6 million, or 26.3% in fiscal 2017 as compared to fiscal 2016, primarily due to a decrease of RF product revenue as therewere larger sales to certain customers in the prior fiscal year.2016 Compared to 2015North America revenue in fiscal 2016 increased $3.9 million, or 3.0%, compared to fiscal 2015. This was primarily due to a $5.3 million increase in productrevenue mostly related to higher sales of network and embedded products. This was partially offset by a decrease in cellular gateway products and a decreasein service revenue mostly related to Digi Wireless Design Services.EMEA revenue decreased $2.6 million, or 5.5%, in fiscal 2016 from fiscal 2015. The British Pound and Euro weakened compared to the U.S. Dollar duringfiscal 2016, which contributed to the decrease in revenue. In addition revenue decreased for cellular-related and RF products, partially offset by an increase inrevenue from embedded products compared to the same periods in the prior year.Revenue in Asian countries decreased by $2.5 million, or 11.0%, in fiscal 2016 compared to fiscal 2015 mostly related to decreased volume of networkproducts.Latin America revenue increased by $0.4 million, or 6.9%, in fiscal 2016 from fiscal 2015, primarily due to increased RF product sales in fiscal 2016.26Table of ContentsITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)Foreign currency rates compared to the prior year's rates had an unfavorable impact on revenue of $0.4 million, $1.1 million and $3.4 million for fiscal 2017,2016 and 2015, respectively.Revenue by Distribution ChannelThe following table presents our revenue by distribution channel: Revenue % of Revenue($ in millions) 2017 2016 2015 2017 2016 2015Direct/OEM channel $70.0 $68.8 $77.9 38.5% 33.9% 38.2%Distributors channel 111.6 134.2 125.9 61.5% 66.1% 61.8%Total revenue $181.6 $203.0 $203.8 100.0% 100.0% 100.0%2017 Compared to 2016Revenue in fiscal 2017 in our Direct/OEM channel increased by $1.2 million, or 1.7%, compared to the prior fiscal year primarily resulting from increasedrevenues from our service offerings that are almost exclusively sold through direct channels. During fiscal 2017, revenue from our distributors decreased by$22.6 million, or 16.8%, compared to fiscal 2016. As described above, we experienced lower sales in fiscal 2017 particularly in network, embedded and RFproducts compared to fiscal 2016.2016 Compared to 2015Revenue in fiscal 2016 in our Direct/OEM channel decreased by $9.1 million, or 11.7%, compared to the prior fiscal year primarily resulting from lower salesof cellular and RF products and from our service offerings. During fiscal 2016, revenue from our distributors increased by $8.3 million, or 6.6%, compared tofiscal 2015. We experienced significant sales of terminal servers to a large customer in fiscal 2016. In addition we had significant customers sales ofembedded products as they moved their new initiatives to production.GROSS PROFIT2017 Compared to 2016Gross profit was $87.2 million and $99.7 million in fiscal 2017 and 2016, respectively, a decrease of $12.5 million, or 12.5%.

The hardwareproduct gross margin for fiscal 2017 was 48.7% compared to 50.1% in fiscal 2016. Gross margin was impacted negatively by lower hardware product revenueand product mix during fiscal 2017 compared to the prior fiscal year. This was driven primarily by the decline of the network category, which includestraditionally higher margin products compared to our other products.Service gross profit was $7.5 million and $2.2 million in fiscal 2017 and 2016, respectively, an increase of $5.3 million, or 234.8%. The service gross marginfor fiscal 2017 was 49.5% compared to 32.5% in fiscal 2014. The increase in gross margin is primarily due to the increase in service and solutions revenuemostly related to Digi Smart Solutions™ during fiscal 2017 compared to the prior fiscal year.Gross profit was negatively impacted by amortization of $1.4 million and $0.9 million in fiscal 2017 and 2016, respectively, resulting in a decrease in grossprofit by $0.5 million.2016 Compared to 2015Gross profit was $99.7 million and $97.1 million in fiscal 2016 and 2015, respectively, an increase of $2.6 million, or 2.6%.

The hardwareproduct gross margin for fiscal 2016 was 50.1% compared to 48.9% in fiscal 2015. The increase was driven primarily by strong revenue performance in ournetwork category which traditionally has higher margin products. In addition, we realized manufacturing cost reductions across many of our product lines infiscal 2016.27Table of ContentsITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)Service gross profit was $2.2 million and $2.8 million in fiscal 2016 and 2015, respectively, a decrease of $0.6 million, or 19.3%. The service gross marginfor fiscal 2016 was 32.5% compared to 33.3% in fiscal 2015. This primarily was a result of lower revenue from Digi Wireless Design Services.Gross profit was positively impacted by amortization of $0.9 million in fiscal 2016 compared to $1.3 million in fiscal 2015, resulting in an increase in grossprofit by $0.4 million.OPERATING EXPENSES2017 Compared to 2016Operating expenses were $78.4 million in fiscal 2017, a decrease of $4.2 million, or 5.1%, compared to $82.6 million in fiscal 2016. Below is a summary ofour operating expenses by function:Sales and marketing expenses were $34.0 million and $33.8 million in fiscal 2017 and 2016, respectively, an increase of $0.2 million or 0.3%. The increasewas primarily due to incremental expenses for SMART Temps of $1.9 million, partially offset by a reduction in compensation-related expenses of $1.8million mostly related to lower incentive compensation expense.Research and development expenses were $28.6 million and $31.0 million in fiscal 2017 and 2016, respectively, a decrease of $2.4 million or 7.7%. Thedecrease was due primarily to lower compensation-related expenses of $3.5 million mostly related to lower incentive compensation expenses increased dueto decreased company performance in fiscal 2017. This was partially offset by an increase of $0.7 million in incremental expenses for SMART Temps.General and administrative expenses were $13.3 million and $17.0 million in fiscal 2017 and 2016, respectively, a decrease of $3.7 million or 21.7%. Thiswas primarily due to a net decrease of $3.7 million for adjustments to our contingent consideration liability accruals. In addition we realized lowercompensation and employee-related expenses of $2.6 million mostly related to increased incentive compensation expenses due to decreased companyperformance in fiscal 2017. This was partially offset by and increase in acquisition expenses of $1.1 million and incremental expenses for SMART Temps of$1.5 million.Restructuring expenses were $2.5 million and $0.7 million in fiscal 2017 and fiscal 2016, respectively, an increase of $1.8 million. For further information onrestructuring, see Note 10 to our Consolidated Financial Statements.2016 Compared to 2015Operating expenses were $82.6 million in fiscal 2016, a decrease of $3.6 million, or 4.2%, compared to $86.2 million in fiscal 2015. Below is a summary ofour operating expenses by function:Sales and marketing expenses were $33.8 million and $37.6 million in fiscal 2016 and 2015, respectively, a decrease of $3.8 million or 9.9%. This decreasewas due primarily to decreased compensation and employee-related expenses of $3.0 million as a result of reduced headcount. Travel and entertainmentexpenses also decreased by $0.3 million.Research and development expenses were $31.0 million and $29.9 million in fiscal 2016 and 2015, respectively, an increase of $1.1 million or 3.4%.Compensation and employee-related expenses increased by $1.5 million as a result of underutilization of billable research and development resources as wellas increased contract labor costs. Outside services for testing and certifications increased by $0.3 million. This was partially offset by decreases of $0.8million in travel and entertainment, occupancy and other miscellaneous research and development costs.General and administrative expenses were $17.0 million and $18.3 million in fiscal 2016 and 2015, respectively, a decrease of $1.3 million or 7.0%. Thedecrease is primarily related to compensation-related expenses of $0.7 million, of which $0.3 million related to Chief Executive Officer transition expensesincurred in fiscal 2015. In addition there was a decrease in expenses of $0.7 million as we reduced the fair value of the contingent consideration associatedwith our acquisition of Bluenica (see Note 2 to our Consolidated Financial Statements).Restructuring expenses were $0.7 million in fiscal 2016 and $0.4 million in fiscal 2015. For further information on restructuring expenses, see Note 10 to ourConsolidated Financial Statements.28Table of ContentsITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)OTHER INCOME (EXPENSE), NET2017 Compared to 2016We recorded other income, net of $0.7 million in fiscal 2017 compared to other expense, net of $0.4 million in fiscal 2016. In fiscal 2017 we recorded foreigncurrency net transaction gains of $0.1 million compared to fiscal 2016 in which we recorded $0.7 million of foreign currency net transaction losses. Ourinterest income on marketable securities and cash and cash equivalents increased in fiscal 2017 from fiscal 2016. Our average investment balance decreasedfrom $102.3 million in fiscal 2016 to $94.6 million in fiscal 2017, however, we earned an average interest rate of 0.7% and 0.4% in fiscal 2017 and 2016,respectively.2016 Compared to 2015Total other income (expense), net was comprised of other expense, net of $0.4 million in fiscal 2016 compared to other income, net of $2.2 million in fiscal2015. In fiscal 2016, we recorded $0.7 million of foreign currency net transaction losses compared to fiscal 2015 in which we recorded $0.6 million of foreigncurrency net transaction gains and a $1.4 million of gain from the settlement of a property and casualty insurance claim related to the replacement of ourcapital equipment destroyed in the fire at our subcontract manufacturer's location. Our interest income on marketable securities and cash and cash equivalentsincreased from fiscal 2015 to fiscal 2016 as our average investment balance increased from $74.0 million in fiscal 2015 to $102.3 million in fiscal 2016. Weearned an average interest rate of 0.4% and 0.3% in fiscal 2016 and 2015, respectively.INCOME TAXESOur effective income tax rates were 1.3%, 19.2% and 28.1% for fiscal 2017, 2016 and 2015, respectively. Our effective tax rate will vary based on a variety offactors, including overall profitability, the geographical mix of income before taxes and related statutory tax rate in each jurisdiction, and discrete events,such as settlements of audits (see Note 11 to our Consolidated Financial Statements).During fiscal 2017, we recorded net tax benefits of $1.0 million, primarily from the reversal of tax reserves due to the expiration of statutes of limitation fromU.S. and foreign tax jurisdictions.During fiscal 2016, we recorded net tax benefits of $1.5 million, primarily from the reinstatement of the federal research and development tax credit forcalendar year 2015 and the reversal of tax reserves due to the expiration of statutes of limitation from U.S. and foreign tax jurisdictions. In addition, we filedamended income tax returns resulting in an additional domestic refund related to qualified manufacturing activities.During fiscal 2015, we recorded net tax benefits of $0.8 million, resulting from the reinstatement of the research and development tax credit for calendar year2014, reversal of tax reserves due to the expiration of statute of limitations from U.S. and foreign tax jurisdictions and reversal of tax reserves due to theresolution of tax audits.INFLATIONManagement believes that during fiscal 2017, 2016 and 2015, inflation has not had a material effect on our consolidated statement of operations or financialposition.29Table of ContentsITEM 7.

Hardware productrevenue decreased $29.6 million, or 15.1%, in fiscal 2017 as compared to fiscal 2016 as performance decreased in all product categories. This was partiallyoffset by an increase in services revenue from this segment of $1.5 million, or 25.3%, in fiscal 2017 as compared to fiscal 2016 as revenue for Digi WirelessDesign Services, Digi Remote Manager® and support services all increased. Revenue for this segment was unfavorably impacted by $0.4 million for the yearended September 30, 2017 primarily due to the weakening of the British Pound and Euro compared to the U.S. Dollar.2016 Compared to 2015M2M segment revenue was $202.3 million in fiscal 2016 compared to $203.8 million in fiscal 2015, a decrease of $1.5 million, or 0.8%. Services revenuefrom this segment decreased $2.2 million, or 25.8%, in fiscal 2016 as compared to fiscal 2015 as revenue for Digi Wireless Design Services, Digi RemoteManager® and support services all decreased. This was partially offset by an increase in hardware product revenue of $0.6 million, or 0.3%, in fiscal 2017 ascompared to fiscal 2016 due to increases in network and embedded products increased, partially offset by decreases in cellular routers and gateways and RFproducts. Revenue for this segment was unfavorably impacted by $1.1 million for the year ended September 30, 2016 primarily due to the weakening of theBritish Pound and Euro compared to the U.S. Dollar.M2M OPERATING INCOME2017 Compared to 2016Operating income was $12.8 million in fiscal 2017 compared to $18.8 million in fiscal 2016, a decrease of $6.0 million, or 32.0%. The decrease was primarilydue to a reduction in our gross profit of $16.0 million, or 16.0%, offset by a decrease in operating expenses of $10.0 million, or 12.3%. The decrease inoperating expenses was due primarily to a reduction in employee-related expenses of $9.4 million related to a reduction in incentive plan compensation asthresholds were not met. In addition we realized a net decrease of $3.7 million for adjustment to our contingent consideration liability accruals. This partiallyoffset by an increase of $1.8 million for restructuring charges (see Note 10 to our Consolidated Financial Statements). In addition there was an increase of$1.7 million in outside services and professional fees of which $1.1 million related to acquisition costs.30Table of ContentsITEM 7.

The increase wasprimarily due to an increase in our gross profit of $2.7 million, or 2.8% and a decrease in operating expenses of $5.2 million, or 6.1%. The decrease inoperating expenses was due primarily to a reduction in employee-related expenses of $3.3 million mostly related to a reduction in incentive plancompensation as thresholds were not met. In addition, we had decreases of $0.9 million for travel and entertainment expense, $0.7 million for occupancyexpenses, and a decrease of $0.7 million for earn-out adjustment made in fiscal 2016. This was partially offset by an increase in professional fees of $0.6million and additional restructuring charges of $0.3 million.SOLUTIONS Year ended September 30,% Increase(decrease)($ in thousands)2017 20162017compared to2016Solutions revenue$7,397 100.0 % $711 100.0 %940.4Cost of sales: Cost of solutions2,954 40.0 446 62.7562.3Amortization of intangibles1,074 14.5 398 56.0169.8Total cost of sales4,028 54.5 844 118.7377.3Gross profit3,369 45.5 (133) (18.7)2,633.1Total operating expenses7,366 99.5 1,584 222.8365.0Operating loss$(3,997) (54.0)% $(1,717) (241.5)%132.8SOLUTIONS REVENUE2017 Compared to 2016Solutions segment revenue was $7.4 million in fiscal 2017 compared to $0.7 million in fiscal 2016, an increase of $6.7 million, or 940.4%. The increase wasdriven primarily by the continued growth and expansion of the Solutions segment, which included incremental revenue from our recent acquisitions ofSMART Temps and FreshTemp of $6.1 million in fiscal 2017 as compared to fiscal 2016 (see Note 2 to our Consolidated Financial Statements). As ofSeptember 30, 2017, we are now servicing nearly 14,000 customer sites and our recurring revenue from this segment continues to grow.SOLUTIONS OPERATING LOSS2017 Compared to 2016Operating loss was $4.0 million in fiscal 2017 compared to $1.7 million in fiscal 2016, an increase of $2.3 million, or 132.8%. The increase in operating losswas primarily due to an increase in operating expenses of $5.8 million, or 365.0%. This was primarily driven by the recent acquisitions of SMART Temps andFreshTemp. This was partially offset by an increase in our gross profit of $3.5 million, or 2,633.1%. We expect our Solutions gross margin to increase infuture periods as recurring revenue from this segment increases.LIQUIDITY AND CAPITAL RESOURCESWe have financed our operations principally with funds generated from operations. We held cash, cash equivalents and short-term marketable securities of$110.2 million, $134.1 million and $92.2 million at September 30, 2017, 2016 and 2015, respectively. Our working capital was $156.4 million, $171.8million and $137.0 million at September 30, 2017, 2016 and 2015, respectively. The decrease of cash, cash equivalents and short-term marketable securitiesand working capital during fiscal 2017 was attributable primarily to the acquisitions of FreshTemp in November 2016 and SMART Temps in January 2017.In October 2017 we purchased all the outstanding interest of TempAlert.

Thisnet decrease was primarily due to a decrease of $7.8 million of net income adjusted for non-cash items and a net decrease in cash flows resulting from changesin operating assets and liabilities of $16.8 million. The net decrease in cash flows resulting from changes in operating assets and liabilities of $16.8 millionprimarily due to a decrease of $8.5 million resulting from an increase in inventory in fiscal 2017 compared to fiscal 2016, a $5.2 million decrease in cashflows related to accounts payable and a $6.7 million decrease in accrued liabilities primarily resulting from payouts of incentive compensation accruals onfiscal 2016 incentive compensation. This was partially offset by an increase of $2.0 million increase in cash flows as our accounts receivable increased by asmaller amount in fiscal 2017 compared to fiscal 2016 and $1.6 million related to income taxes payable.Net cash used in investing activities was $3.7 million in fiscal 2017 compared $3.8 million in fiscal 2016, an increase of $0.1 million. There were netmaturities of marketable securities in fiscal 2017 compared to net purchases of marketable securities in fiscal 2016 which accounted for a $26.2 millionincrease. In addition, there was an increase of $0.9 million related to fewer capital expenditures and $0.2 million of additional proceeds from the sale ofEtherios. This was partially offset by a decrease of $27.3 million related to additional expenditures for acquisitions (see Note 2 to the Consolidated FinancialStatements).Net cash provided by financing activities was $3.1 million in fiscal 2017 compared to $7.7 million in fiscal 2016. There were $3.8 million fewer proceedsfrom exercises of stock options and employee stock purchase plan transactions in fiscal 2017 compared to fiscal 2016. We also had $0.5 million acquisitionearn-out payments in fiscal 2017 and $0.4 million fewer repurchases of common stock in fiscal 2017 compared to fiscal 2016.2016 Compared to 2015Net cash provided by operating activities was $27.1 million during fiscal 2016 compared to $14.1 million during fiscal 2015, a net increase of $13.0 million.This net increase is due to an increase of $8.4 million in net income adjusted for non-cash items and a net increase in cash flows resulting from operatingassets and liabilities of $4.6 million. The increase in cash flows related to changes in operating assets and liabilities was primarily due to an increase of $5.9million resulting from a reduction in inventory, an increase in accounts payable of $5.4 million, and an increase of $1.0 million resulting from a reduction ofaccounts receivable, prepaids and other assets. This was partially offset by a reduction of accrued liabilities of $5.7 million and a reduction of $2.0 million oftaxes payable.Net cash used by investing activities was $3.8 million in fiscal 2016 compared to $19.5 million in fiscal 2015, a net decrease of $15.7 million. We purchased$15.3 million fewer marketable securities in fiscal 2016 as compared to fiscal 2015. We received $2.8 million in proceeds from the sale of Etherios, net ofcash sold, in fiscal 2016 and spent $1.8 million less for capital expenditures in fiscal 2016 compared to fiscal 2015. This was partially offset by cash used forthe acquisition of Bluenica of $2.9 million and proceeds from an insurance settlement in fiscal 2015 of $1.4 million.Net cash provided by financing activities was $7.7 million in fiscal 2016 compared to $5.1 million in fiscal 2015, an increase of $2.6 million. Werepurchased $1.8 million less of our common stock in fiscal 2016 compared to fiscal 2015, and received $0.8 million of additional proceeds related toexercises of stock options and employee stock purchase plan transactions.We expect positive cash flows from operations and believe that our current cash, cash equivalents and marketable securities balances, cash generated fromoperations and our ability to secure debt and/or equity financing will be sufficient to fund our business operations and capital expenditures for the nexttwelve months and beyond.32Table of ContentsITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)At September 30, 2017, our total cash and cash equivalents and marketable securities balance, including long-term marketable securities was $115.0 million.Approximately $31.7 million of cash and cash equivalents was being held by our controlled foreign subsidiaries at September 30, 2017. At September 30,2017, we had $34.6 million of accumulated undistributed foreign earnings that are indefinitely reinvested in non-U.S. subsidiaries, resulting in slightly morethan half of our cash and cash equivalents being held by non-U.S. subsidiaries. Although we have no current need to repatriate historical earnings in the formof cash in the United States, if we change our assertion from indefinitely reinvesting undistributed foreign earnings, we would have to accrue applicabletaxes. The amount of any taxes and the application of any tax credits would be determined based on the income tax laws at the time of such repatriation.Under current tax laws, we estimate the unrecognized deferred tax liability to be up to $0.6 million.CONTRACTUAL OBLIGATIONSThe following summarizes our contractual obligations at September 30, 2017: Payments due by fiscal period($ in thousands) Total Less than 1 year 1-3 years 3-5 years ThereafterOperating leases $3,761 $1,398 $1,757 $485 $121The operating lease agreements included above primarily relate to office space. The table above does not include possible payments for uncertain taxpositions. Our reserve for uncertain tax positions, including accrued interest and penalties, was $1.5 million as of September 30, 2017. Due to the nature ofthe underlying liabilities and the extended time often needed to resolve income tax uncertainties, we cannot make reliable estimates of the amount or timingof future cash payments that may be required to settle these liabilities.The above table also does not include those obligations for royalties under license agreements as these royalties are calculated based on future sales oflicensed products and we cannot make reliable estimates of the amount of cash payments.FOREIGN CURRENCYWe are exposed to foreign currency transaction risk associated with certain sales being denominated in Euros, British Pounds, Japanese Yen and CanadianDollar and foreign currency translation risk as the financial position and operating results of our foreign subsidiaries are translated into U.S. Dollars forconsolidation. We manage our net asset or net liability position for U.S. dollar accounts in our foreign locations to reduce our foreign currency risk. We havenot implemented a formal hedging strategy to reduce foreign currency risk.During 2017, we had approximately $63.9 million of revenue related to foreign customers including export sales, of which $18.2 million was denominated inforeign currency, predominantly the Euro and British Pound. During fiscal 2016 and 2015, we had approximately $71.5 million and $76.2 million,respectively, of revenue to foreign customers including export sales, of which $22.9 million and $21.3 million, respectively, were denominated in foreigncurrency, predominantly the Euro and British Pound. In future periods, we expect that the majority of our sales will be in U.S. Dollar.In June 2016, the U.K. held a referendum in which voters approved Brexit. The announcement of Brexit caused significant volatility in global stock marketsand currency exchange rate fluctuations that resulted in the strengthening of the U.S. dollar against the British pound. Brexit could cause disruptions to andcreate uncertainty surrounding our business, including continued increased volatility in exchange rates, as the future terms of the U.K.’s relationship with theE.U. are determined.RECENT ACCOUNTING DEVELOPMENTSFor information on new accounting pronouncement, see Note 1 to our Consolidated Financial Statements.CRITICAL ACCOUNTING POLICIES AND ESTIMATESOur discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have beenprepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these consolidated financialstatements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, the disclosure ofcontingent assets and liabilities and the values of purchased assets and assumed liabilities in acquisitions. We base our estimates on historical experience andvarious33Table of ContentsITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carryingvalues of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.We believe the following critical accounting policies impact our more significant judgments and estimates used in the preparation of our consolidatedfinancial statements.REVENUE RECOGNITIONOur revenue is derived primarily from the sale of wired and wireless hardware products to our distributors and Direct/OEM customers. We recognize hardwareproduct revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, collectability isreasonably assured and there are no post-delivery obligations, other than warranty. Under these criteria, product revenue generally is recognized uponshipment of product to customers. Sales to authorized domestic distributors and Direct / OEMs are made with certain rights of return and price adjustmentprovisions. Estimated reserves for future returns and pricing adjustments are established by us based on an analysis of historical patterns of returns and priceadjustments as well as an analysis of authorized returns compared to received returns and distribution sales for the current period. Estimated reserves forfuture returns and price adjustments are charged against revenue in the same period as the corresponding sales are recorded. Material differences between thehistorical trends used to determine estimated reserves and actual returns and pricing adjustments could result in a material change to our consolidated resultsof operations or financial position. We have applied consistent methodologies for estimating reserves for future returns and pricing adjustments for all yearspresented. The reserve for future returns and pricing adjustments was $2.2 million at September 30, 2017 and $2.0 million at September 30, 2016.Revenue recognized for service revenue as a percentage of total revenue represented 8.3%, 3.4% and 4.1% in fiscal 2017, 2016 and 2015, respectively. Ourservice revenue is derived primarily from our Digi Wireless Design Services and our Digi Smart Solutions™. Our equipment and implementation fees arerecorded as a sale up–front due to these items having stand–alone value to the customer because the customer can utilize our equipment with othermonitoring services or use our monitoring services with hardware purchased from other vendors. Our installation charges are recorded when the product isinstalled. Our subscription revenue is recorded on a monthly basis. These subscriptions are generally for one year, but can be as long as three years, and maycontain an evergreen renewal provision. Generally, our subscription renewal charges per month are the same as the original contract term. We also have someservice revenue that is derived from our Digi Remote Manager®, which is a platform-as-a-service (PaaS) offering in which customers pay for servicesconsumed in terms of devices being managed and monitored, or as a monthly service fee for access to information. In addition, we have small amounts ofrevenue from our support services. We recognize service revenue from our Digi Wireless Design Services, Digi Smart Solutions™ and Digi Remote Manager®based upon performance, including final product delivery and customer acceptance. In addition, we recognize small amounts of revenue from supportservices which is recognized over the life of the contract, and training as the services are performed.MARKETABLE SECURITIESWe regularly monitor and evaluate the realizable value of our marketable securities. When assessing marketable securities for other-than-temporary declinesin value, we consider several factors. These factors include: how significant the decline in value is as a percentage of the original cost, how long the marketvalue of the investment has been less than its original cost, the underlying factors contributing to a decline in the prices of securities in a single asset class,the performance of the issuer’s stock price in relation to the stock price of its competitors within the industry, expected market volatility, analystrecommendations, the views of external investment managers, any news or financial information that has been released specific to the investee and theoutlook for the overall industry in which the issuer operates. If events and circumstances indicate that a decline in the value of these securities has occurredand is other-than-temporary, we would record a charge to other income (expense).ACCOUNTS RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTSWe maintain an allowance for doubtful accounts, which reflects the estimate of losses that may result from the inability of some of our customers to makerequired payments. The estimate for the allowance for doubtful accounts is based on known circumstances regarding collectability of customer accounts andhistorical collections experience. If the financial condition of one or more of our customers were to deteriorate, resulting in an inability to make payments,additional allowances may be required. Material differences between the historical trends used to estimate the allowance for doubtful accounts and actual34Table of ContentsITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)collection experience could result in a material change to our consolidated results of operations or financial position. The allowance for doubtful accountswas $0.3 million at September 30, 2017 and $0.2 million at September 30, 2016.INVENTORIESInventories are stated at the lower of cost or fair market value, with cost determined using the first-in, first-out method. We reduce the carrying value of ourinventories for estimated excess and obsolete inventories equal to the difference between the cost of inventory and its estimated realizable value based uponassumptions about future product demand and market conditions. Once the new cost basis is established, the value is not increased with any changes incircumstances that would indicate an increase in value after the re-measurement. If actual product demand or market conditions are less favorable than thoseprojected by management, additional inventory write-downs may be required that could result in a material change to our consolidated results of operationsor financial position. We have applied consistent methodologies for the net realizable value of inventories.GOODWILLGoodwill represents the excess of cost over the fair value of identifiable assets acquired. In a business combination, goodwill is capitalized at the acquisitiondate. It is measured at fair value, which is the excess of the acquisition price for shares in a company over the acquired net assets. The net assets include thefair values of the acquired identifiable assets less the assumed liabilities and contingent liabilities.Goodwill is tested for impairment on an annual basis as of June 30, or more frequently if events or circumstances occur which could indicate impairment. Thecalculation of goodwill impairment requires us to make assumptions about the fair value of our reporting unit(s), which historically has been approximatedby using our market capitalization plus a control premium for our one reporting unit. Control premium assumptions require judgment and actual results maydiffer from assumed or estimated amounts.As of the third quarter of fiscal 2017, we determined that we have two reportable operating segments, our Solutions segment and our M2M segment (see Note5 to the Condensed Consolidated Financial Statements). As a result, we concluded that the Solutions segment and the M2M segment constitute separatereporting units for purposes of the ASC 350-20-35 "Goodwill Measurement of Impairment" assessment and both units were tested individually forimpairment.Our test for potential goodwill impairment is a two-step approach. First, we estimate the fair values for each reporting unit by comparing the fair value to thecarrying value. If the carrying value of the reporting unit exceeds its estimated fair value, then we conduct the second step, which requires us to measure theamount of the impairment loss. The impairment loss, if any, is calculated by comparing the implied fair value of the goodwill to its carrying amount. Tocalculate the implied fair value of goodwill, the fair value of the reporting unit’s assets and liabilities, excluding goodwill, is estimated. The excess of the fairvalue of the reporting unit over the amount assigned to its assets and liabilities, excluding goodwill, is the implied fair value of the reporting unit’s goodwill.At June 30, 2017, we had a total of $98.6 million of goodwill on our Condensed Consolidated Balance Sheet for the M2M reporting unit and the implied fairvalue of this reporting unit exceeded its carrying value by approximately 7%. At June 30, 2017, we had a total of $32.5 million of goodwill on ourCondensed Consolidated Balance Sheet for the Solutions reporting unit and the implied fair value of this reporting unit exceeded its carrying value byapproximately 8%. Based on that data, we concluded that no impairment was indicated for either reporting unit and we were not required to complete thesecond step of the goodwill impairment analysis. No goodwill impairment charges were recorded. During the fourth quarter of fiscal 2017, we assessedvarious qualitative factors to determine whether or not an additional goodwill impairment assessment was required as of September 20, 2017, and weconcluded that no additional impairment assessment was required.Implied fair values, for both reporting units were each calculated on a standalone basis using a weighted combination of the income approach and marketapproach.The income approach indicates the fair value of a business based on the value of the cash flows the business or asset can be expected to generate in the future.A commonly used variation of the income approach used to value a business is the discounted cash flow (DCF) method. The DCF method is a valuationtechnique in which the value of a business is estimated on the earnings capacity, or available cash flow, of that business. Earnings capacity represents theearnings available for distribution to capital holders after consideration of the reinvestment required for future growth. Significant judgment is35Table of ContentsITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)required to estimate the amount and timing of future cash flows for each reporting unit and the relative risk of achieving those cash flows.The market approach indicates the fair value of a business or asset based on a comparison of the business or asset to comparable publicly traded companies orassets and transactions in its industry as well as prior company or asset transactions. This approach can be estimated through the guideline company method.This method indicates fair value of a business by comparing it to publicly traded companies in similar lines of business. After identifying and selecting theguideline companies, we make judgments about the comparability of the companies based on size, growth rates, profitability, risk, and return on investmentin order to estimate market multiples. These multiples are then applied to the reporting units to estimate a fair value.In addition, the implied fair values of each reporting unit were added together to get an indicated value of total equity to which a range of indicated value oftotal equity was derived. This range was compared to the total market capitalization of $269.4 million as of June 30, 2017, which implied a range of controlpremiums of 16.6% to 24.4%. This range of control premiums falls below the control premiums observed in the last five years in the communicationsequipment industry. As a result, the market capitalization reconciliation analysis proved support for the reasonableness of the fair values estimated for eachindividual reporting unit.Should the facts and circumstances surrounding our assumptions change, the first step of our goodwill impairment analysis may fail. Assumptions andestimates to determine fair values are complex and often subjective. They can be affected by a variety of factors, including external factors such as industryand economic trends, and internal factors such as changes in our business strategy and our internal forecasts. For example, if our future operating results donot meet current forecasts or if we experience a sustained decline in our market capitalization that is determined to be indicated of a reduction in fair value ofone or more of our reporting units, we may be required to record future impairment charges for goodwill.CONTINGENT CONSIDERATIONWe measure our contingent consideration liabilities recognized in connection with business combinations at fair value on a recurring basis using significantunobservable inputs classified within Level 3 of the fair value hierarchy as defined in ASC 820 "Fair Value Measurement". We used a probability-weighteddiscounted cash flow approach as a valuation technique to determine the fair value of the contingent consideration on the acquisition date. At eachsubsequent reporting period, the fair value is re-measured with the change in fair value recognized in general and administrative expense and interest expensein our Condensed Consolidated Statements of Operations. Amounts, if any, paid to the seller in excess of the amount recorded on the acquisition date will beclassified as cash flows used in operating activities. Payments to the seller not exceeding the acquisition-date fair value of the contingent consideration willbe classified as cash flows used in financing activities. At September 30, 2017 and 2016, the fair value of our contingent consideration was $6.4 million and$10.0 million, respectively.INCOME TAXESWe operate in multiple tax jurisdictions both in the U.S. and outside of the U.S. Accordingly, we must determine the appropriate allocation of income to eachof these jurisdictions. This determination requires us to make several estimates and assumptions. Tax audits associated with the allocation of this income, andother complex issues, may require an extended period of time to resolve and could result in adjustments to our income tax balances that are material to ourconsolidated financial position and results of operations and could result in potential cash outflows.We have unrecognized tax benefits of $1.3 million at September 30, 2017. We expect that it is reasonably possible that the total amounts of unrecognized taxbenefits will decrease approximately $0.1 million over the next 12 months due to the expiration of various statutes of limitations. The total amount ofunrecognized tax benefits that if recognized would affect our effective tax rate is $1.2 million. We recognize interest and penalties related to income taxmatters in income tax expense.WARRANTIESIn general, we warrant our products to be free from defects in material and workmanship under normal use and service. The warranty periods generally rangefrom one to five years. We typically have the option to repair or replace products we deem defective due to material or workmanship. Estimated warrantycosts are accrued in the period that the related revenue is recognized based upon an estimated average per unit repair or replacement cost applied to theestimated number of units under warranty. These estimates are based upon historical warranty incidents and are evaluated on an ongoing basis to ensure theadequacy of the warranty accrual. The product warranty accrual was $1.0 million at both September 30, 2017 and 2016.36Table of ContentsITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKINTEREST RATE RISKOur exposure to interest rate risk relates primarily to our investment portfolio. We do not use derivative financial instruments to hedge against interest raterisk.FOREIGN CURRENCY RISKWe are exposed to foreign currency transaction risk associated with certain sales being denominated in Euros, British Pounds, Japanese Yen or CanadianDollar and foreign currency translation risk as the financial position and operating results of our foreign subsidiaries are translated into U.S. Dollars forconsolidation. We manage our net asset or net liability position for non-functional currency accounts, primarily the U.S. dollar accounts in our foreignlocations to reduce our foreign currency risk. We have not implemented a formal hedging strategy.The table below compares the average monthly exchange rates of the Euro, British Pound, Japanese Yen and Canadian Dollar: Fiscal year endedSeptember 30, % increase 2017 2016 (decrease)Euro1.1047 1.1112 (0.6)%British Pound1.2673 1.4261 (11.1)%Japanese Yen0.0090 0.0090 — %Canadian Dollar0.7615 0.7552 0.8 %A 10.0% change from the 2017 average exchange rate for the Euro, British Pound, Yen and Canadian Dollar to the U.S. Dollar would have resulted in a 1.0%increase or decrease in fiscal 2017 annual revenue and a 2.2% increase or decrease in stockholders' equity at September 30, 2017. The above analysis doesnot take into consideration any pricing adjustments we may make in response to changes in the exchange rate.CREDIT RISKWe have some exposure to credit risk related to our accounts receivable portfolio. Exposure to credit risk is controlled through regular monitoring ofcustomer financial status, credit limits and collaboration with sales management on customer contacts to facilitate payment.Investments are made in accordance with our investment policy and consist of certificates of deposit, money market funds, corporate bonds and governmentmunicipal bonds. We may have some credit exposure related to the fair value of our securities, which could change based on changes in market conditions. Ifmarket conditions deteriorate or, if these securities experience credit rating downgrades, we may incur impairment charges for securities in our investmentportfolio.37Table of ContentsITEM 8.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIESBusiness DescriptionWe are a leading global provider of business and mission-critical and Internet of Things (IoT) connectivity products and services. We help our customerscreate next-generation connected products and deploy and manage critical communications infrastructures in demanding environments with high levels ofsecurity and reliability. As of the fiscal quarter ended June 30, 2017, we determined that we have two reportable operating segments for purposes of ASC 280-10-50 "Segments Reporting": (i) machine-to-machine (M2M), and (ii) Solutions.Our M2M segment consists primarily of distinct communications products and communication product development services. Among other things, theseproducts and services help our customers create next generation connected products and deploy and manage critical communications infrastructures indemanding environments with high levels of security and reliability. We create secure, easy to implement embedded solutions and services to help customersbuild IoT connectivity. We also deploy ready to use, complete box solutions to connect remote equipment. We also offer dedicated professional services forthe design of specialized wireless communications products for customers. Finally, through this segment we offer managed cloud services that enablecustomers to capture and manage data from devices they connect to networks. The products and services of this segment are used by a wide range ofbusinesses and institutions.Our Solutions segment offers wireless temperature and other environmental condition monitoring services as well as employee task management services.These products and services are provided to food service, transportation, education, healthcare and pharma, and industrial markets which are marketed as DigiSmart Solutions™.Discontinued OperationsOn October 23, 2015, we sold all of the outstanding stock of our wholly owned subsidiary, Etherios Inc. (Etherios) to West Monroe Partners, LLC. Becausethe sale of Etherios represented a strategic shift that will have a major effect on our operations and financial results, we have classified our Etherios businessas discontinued operations, which requires retrospective application to financial information for all periods presented. Since the cost of segregating theconsolidated statement of cash flows outweighed the benefits, we elected not to segregate our consolidated statement of cash flows as the material items inthe operating and investing sections are disclosed in Note 3 to our Consolidated Financial Statements.Principles of ConsolidationThe consolidated financial statements include our accounts and the accounts of our wholly-owned subsidiaries. All intercompany accounts and transactionshave been eliminated in consolidation.ReclassificationsCertain prior year amounts have been reclassified to conform to our fiscal 2017 presentation. On the Consolidated Balance Sheet for the period endedSeptember 30, 2016, unearned revenue has been reclassified from other current liabilities to its own respective line item. We have reclassified current incometaxes payable to other current liabilities.Beginning in the third fiscal quarter of 2017, we renamed our service revenue and cost of sales to be more descriptive to services and solutions revenue andservices and solutions cost of sales. Beginning with this annual report on Form 10-K, we will also report the amortization within cost of sales on its ownrespective line item. On the Consolidated Statement of Operations for the year ended September 30, 2016 and 2015, we have reclassified the cost of salessections to conform to this presentation. Total revenue and cost of sales remain unchanged.These reclassifications had no impact on our consolidated net sales or our consolidated net income.Cash EquivalentsCash equivalents consist of money market accounts and other highly liquid investments purchased with an original maturity of three months or less. Thecarrying amounts approximate fair value due to the short maturities of these investments. We maintain our cash and cash equivalents in bank accounts which,at times, may exceed federally insured limits. We have not experience any losses in such accounts.45Table of ContentsNOTES TO CONSOLIDATED FINANCIAL STATEMENTS1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)Marketable SecuritiesMarketable securities consist of certificates of deposit, commercial paper, corporate bonds and government municipal bonds. All marketable securities areaccounted for as available-for-sale and are carried at fair value on our consolidated balance sheets with unrealized gains and losses recorded in accumulatedother comprehensive loss within stockholders’ equity. In order to estimate the fair value for each security in our investment portfolio, we obtain quotedmarket prices and trading activity for each security where available. We obtain relevant information from our investment advisor and, if warranted, also mayreview the financial solvency of certain security issuers.We regularly monitor and evaluate the value of our marketable securities. When assessing marketable securities for other-than-temporary declines in value,we consider several factors. These factors include: how significant the decline in value is as a percentage of the original cost, how long the market value ofthe investment has been less than its original cost, the underlying factors contributing to a decline in the prices of securities in a single asset class, theperformance of the issuer’s stock price in relation to the stock price of its competitors within the industry, expected market volatility, analystrecommendations, the views of external investment managers, any news or financial information that has been released specific to the investee and theoutlook for the overall industry in which the issuer operates. If events and circumstances indicate that a decline in the value of a security has occurred and isother-than-temporary, we would record a charge to other (expense) income.Accounts ReceivableAccounts receivable are stated at the amount we expect to collect, which is net of an allowance for doubtful accounts for estimated losses resulting from theinability of our customers to make required payments. The following factors are considered when determining the collectability of specific customeraccounts: customer creditworthiness, past transaction history with the customer, and changes in customer payment terms or practices. In addition, overallhistorical collection experience, current economic industry trends, and a review of the current status of trade accounts receivable are considered whendetermining the required allowance for doubtful accounts. Based on our assessment, we provide for estimated uncollectible amounts through a charge toearnings and a credit to our allowance for doubtful accounts. Balances that remain outstanding after we have used reasonable collection efforts are written offthrough a charge to the allowance for doubtful accounts and a credit to accounts receivable.InventoriesInventories are stated at the lower of cost or fair market value, with cost determined using the first-in, first-out method. Appropriate consideration is given todeterioration, obsolescence and other factors in evaluating fair market value.Property, Equipment and Improvements, NetProperty, equipment and improvements are carried at cost, net of accumulated depreciation. Depreciation is provided by charges to operations using thestraight-line method over the estimated asset useful lives. Furniture and fixtures, purchased software and other equipment are depreciated over a period ofthree to seven years. Building improvements and buildings are depreciated over ten and thirty-nine years, respectively.Expenditures for maintenance and repairs are charged to operations as incurred, while major renewals and betterments are capitalized. The assets and relatedaccumulated depreciation accounts are adjusted for asset retirements and disposals with the resulting gain or loss included in operations.Identifiable Intangible AssetsPurchased proven technology, license agreements, covenants not to compete and other identifiable intangible assets are recorded at fair value when acquiredin a business acquisition, or at cost when not purchased in a business acquisition. All other identifiable intangible assets are amortized on either a straight-line basis over their estimated useful lives of three to thirteen years or based on the pattern in which the asset is consumed. Useful lives for identifiableintangible assets are estimated at the time of acquisition based on the periods of time from which we expect to derive benefits from the identifiable intangibleassets. Amortization of purchased and core technology is included in cost of sales in the Consolidated Statements of Operations. Amortization of all otheracquired identifiable intangible assets is charged to operating expenses as a component of general and administrative expense.46Table of ContentsNOTES TO CONSOLIDATED FINANCIAL STATEMENTS1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)Identifiable intangible assets are reviewed for impairment annually or whenever events or circumstances indicate that undiscounted expected future cashflows are not sufficient to recover the carrying value amount. We measure impairment loss by utilizing an undiscounted cash flow valuation technique usingfair values indicated by the income approach. Impairment losses, if any, would be recorded in the period the impairment is identified. There were no materialimpairments identified in fiscal 2017, 2016 or 2015.GoodwillGoodwill represents the excess of cost over the fair value of identifiable assets acquired. Goodwill is tested for impairment on an annual basis as of June 30,or more frequently if events or circumstances occur which could indicate impairment. The calculation of goodwill impairment requires us to makeassumptions about the fair value of our reporting unit(s), which historically has been approximated by using our market capitalization plus a control premiumfor our reporting unit(s). Control premium assumptions require judgment and actual results may differ from assumed or estimated amounts.As of the third quarter of fiscal 2017, we determined that we have two reportable operating segments, our Solutions segment and our M2M segment (see Note5 to the Condensed Consolidated Financial Statements). As a result, we concluded that the Solutions segment and the M2M segment constitute separatereporting units for purposes of the ASC 350-20-35 "Goodwill Measurement of Impairment" assessment and both units were tested individually forimpairment.Our test for potential goodwill impairment is a two-step approach. First, we estimate the fair values for each reporting unit by comparing the fair value to thecarrying value. If the carrying value of the reporting unit exceeds its estimated fair value, then we conduct the second step, which requires us to measure theamount of the impairment loss. The impairment loss, if any, is calculated by comparing the implied fair value of the goodwill to its carrying amount. Tocalculate the implied fair value of goodwill, the fair value of the reporting unit’s assets and liabilities, excluding goodwill, is estimated. The excess of the fairvalue of the reporting unit over the amount assigned to its assets and liabilities, excluding goodwill, is the implied fair value of the reporting unit’s goodwill.At June 30, 2017, we had a total of $98.6 million of goodwill on our Condensed Consolidated Balance Sheet for the M2M reporting unit and the implied fairvalue of this reporting unit exceeded its carrying value by approximately 7%. At June 30, 2017, we had a total of $32.5 million of goodwill on ourCondensed Consolidated Balance Sheet for the Solutions reporting unit and the implied fair value of this reporting unit exceeded its carrying value byapproximately 8%. Based on that data, we concluded that no impairment was indicated for either reporting unit and we were not required to complete thesecond step of the goodwill impairment analysis. No goodwill impairment charges were recorded. During the fourth quarter of fiscal 2017, we assessedvarious qualitative factors to determine whether or not an additional goodwill impairment assessment was required as of September 20, 2017, and weconcluded that no additional impairment assessment was required.Implied fair values, for both reporting units were each calculated on a standalone basis using a weighted combination of the income approach and marketapproach.The income approach indicates the fair value of a business based on the value of the cash flows the business or asset can be expected to generate in the future.A commonly used variation of the income approach used to value a business is the discounted cash flow (DCF) method. The DCF method is a valuationtechnique in which the value of a business is estimated on the earnings capacity, or available cash flow, of that business. Earnings capacity represents theearnings available for distribution to capital holders after consideration of the reinvestment required for future growth. Significant judgment is required toestimate the amount and timing of future cash flows for each reporting unit and the relative risk of achieving those cash flows.The market approach indicates the fair value of a business or asset based on a comparison of the business or asset to comparable publicly traded companies orassets and transactions in its industry as well as prior company or asset transactions. This approach can be estimated through the guideline company method.This method indicates fair value of a business by comparing it to publicly traded companies in similar lines of business. After identifying and selecting theguideline companies, we make judgments about the comparability of the companies based on size, growth rates, profitability, risk, and return on investmentin order to estimate market multiples. These multiples are then applied to the reporting units to estimate a fair value.In addition, the implied fair values of each reporting unit were added together to get an indicated value of total equity to which a range of indicated value oftotal equity was derived. This range was compared to the total market capitalization of47Table of ContentsNOTES TO CONSOLIDATED FINANCIAL STATEMENTS1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)$269.4 million as of June 30, 2017, which implied a range of control premiums of 16.6% to 24.4%. This range of control premiums falls below the controlpremiums observed in the last five years in the communications equipment industry. As a result, the market capitalization reconciliation analysis provedsupport for the reasonableness of the fair values estimated for each individual reporting unit.Should the facts and circumstances surrounding our assumptions change, the first step of our goodwill impairment analysis may fail. Assumptions andestimates to determine fair values are complex and often subjective. They can be affected by a variety of factors, including external factors such as industryand economic trends, and internal factors such as changes in our business strategy and our internal forecasts. For example, if our future operating results donot meet current forecasts or if we experience a sustained decline in our market capitalization that is determined to be indicated of a reduction in fair value ofone or more of our reporting units, we may be required to record future impairment charges for goodwill. An impairment could have a material effect on ourconsolidated balance sheet and results of operations. We have had no goodwill impairment losses since the adoption of Accounting Standards Codification(ASC) 350, Intangibles-Goodwill and Others, in fiscal 2003.Contingent ConsiderationWe measure our contingent consideration liabilities recognized in connection with business combinations at fair value on a recurring basis using significantunobservable inputs classified within Level 3 of the fair value hierarchy as defined in ASC 820 "Fair Value Measurement". We used a probability-weighteddiscounted cash flow approach as a valuation technique to determine the fair value of the contingent consideration on the acquisition date. At eachsubsequent reporting period, the fair value is re-measured with the change in fair value recognized in general and administrative expense and interest expensein our Condensed Consolidated Statements of Operations. Amounts, if any, paid to the seller in excess of the amount recorded on the acquisition date will beclassified as cash flows used in operating activities. Payments to the seller not exceeding the acquisition-date fair value of the contingent consideration willbe classified as cash flows used in financing activities.WarrantiesIn general, we warrant our hardware products to be free from defects in material and workmanship under normal use and service. The warranty periodsgenerally range from one to five years. We typically have the option to either repair or replace hardware products we deem defective with regard to material orworkmanship. Estimated warranty costs are accrued in the period that the related revenue is recognized based upon an estimated average per unit repair orreplacement cost applied to the estimated number of units under warranty. These estimates are based upon historical warranty incidents and are evaluated onan ongoing basis to ensure the adequacy of the warranty accrual.Treasury Stock We record treasury stock at cost. Treasury stock includes shares purchased from employees for tax withholding purposes related to vesting of restricted stockawards.Revenue RecognitionWe recognize revenue in accordance with authoritative guidance issued by Financial Accounting Standards Board (FASB) related to revenue recognition.Hardware product revenue as a percentage of total revenue was 91.7%, 96.6% and 95.9% in fiscal 2017, 2016 and 2015, respectively. We recognize hardwareproduct revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, collectability isreasonably assured and there are no post-delivery obligations, other than warranty. Under these criteria, product revenue generally is recognized uponshipment of product to customers.Sales to authorized domestic and foreign distributors and Direct / OEMs are made with certain rights of return and price adjustment provisions. Estimatedreserves for future returns and pricing adjustments are established by us based on an analysis of historical patterns of returns and price adjustments as well asan analysis of authorized returns compared to received returns and distribution sales for the current period. Estimated reserves for future returns and priceadjustments are charged against revenue in the same period as the corresponding revenue is recorded.Service revenue as a percentage of total revenue represented 8.3%, 3.4% and 4.1% in fiscal 2017, 2016 and 2015, respectively. Our service revenue is derivedprimarily from our Digi Wireless Design Services and our Digi Smart Solutions™. Our Digi Smart Solutions™ revenue includes subscription revenue, supportand equipment. Our equipment and implementation fees are48Table of ContentsNOTES TO CONSOLIDATED FINANCIAL STATEMENTS1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)recorded as a sale up–front due to these items having stand–alone value to the customer because the customer can utilize our equipment with othermonitoring services or use our monitoring services with hardware purchased from other vendors. Our installation charges are recorded when the product isinstalled. Our subscription revenue is recorded on a monthly basis. These subscriptions are generally for one year, but can be as long as three years, and maycontain an evergreen renewal provision. Generally, our subscription renewal charges per month are the same as the original contract term. We also have someservice revenue that is derived from our Digi Remote Manager®, which is a platform-as-a-service (PaaS) offering in which customers pay for servicesconsumed in terms of devices being managed and monitored, or as a monthly service fee for access to information. In addition, we recognize small amounts ofrevenue from our support services which is recognized over the life of the contract, and training as the services are performed. We recognize service revenuefrom our Digi Wireless Design Services, Digi Smart Solutions™ and Digi Remote Manager® based upon performance, including final product delivery andcustomer acceptance.Research and DevelopmentResearch and development costs are expensed when incurred. Research and development costs include compensation, allocation of corporate costs,depreciation, utilities, professional services and prototypes. Software development costs are expensed as incurred until the point that technologicalfeasibility and proven marketability of the product are established. To date, the time period between the establishment of technological feasibility andcompletion of software development has been short, and no significant development costs have been incurred during that period. Accordingly, we have notcapitalized any software development costs to date.Income TaxesDeferred income taxes are recognized for the tax consequences in future years of differences between the tax basis of assets and liabilities and their financialreporting amounts at each year end based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affecttaxable income. Income tax expense is equal to the tax payable for the period and the change during the period in deferred tax assets and liabilities and alsochanges in income tax reserves.Stock-Based CompensationStock-based compensation expense represents the cost of employee services received in exchange for an award of equity instruments based on the grant datefair value of the award. This cost must be recognized over the period during which an employee is required to provide the service (usually the vesting period).Foreign Currency TranslationFinancial position and results of operations of our international subsidiaries are measured using local currencies as the functional currency, except for ourSingapore location which uses the U.S. Dollar as its functional currency. Assets and liabilities of these operations are translated at the exchange rates in effectat the end of each reporting period. For our larger international subsidiaries, statements of operations accounts are translated at the daily rate. For all otherinternational subsidiaries, our statements of operations accounts are translated at the weighted average rates of exchange prevailing during each reportingperiod. Translation adjustments arising from the use of differing currency exchange rates from period to period are included in accumulated othercomprehensive loss in stockholders’ equity. Gains and losses on foreign currency exchange transactions, as well as translation gains or losses on transactionsdenominated in currencies other than an entity’s functional currency, are reflected in the statement of operations. During fiscal 2017, 2016 and 2015, therewere net transaction gains (losses) of $0.1 million, $(0.7) million and $0.6 million, respectively, that were recorded in other income (expense), net. Wemanage our net asset or net liability position for U.S. dollar accounts in our foreign locations to reduce our foreign currency risk. We have not implemented aformal hedging strategy.Use of Estimates and Risks and UncertaintiesThe preparation of consolidated financial statements in conformity with generally accepted accounting principles in the United States requires managementto make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date ofthe financial statements and the reported amount of revenue and expenses during the reporting period. Actual results could differ from those estimates.Estimates that could significantly affect our results of operations or financial condition involve the assignment of fair values upon acquisition of goodwilland other intangible assets and testing for impairment; the determination of our allowance for doubtful accounts and reserve for future49Table of ContentsNOTES TO CONSOLIDATED FINANCIAL STATEMENTS1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)returns and pricing adjustments; the estimation of our inventory obsolescence, warranty reserve, income tax reserves, contingent consideration and othercontingencies.Comprehensive IncomeOur comprehensive income is comprised of net income, foreign currency translation adjustments and unrealized gains and losses on available-for-salemarketable securities, which are charged or credited to the accumulated other comprehensive loss account in stockholders’ equity.Net Income Per Common ShareBasic net income per common share is calculated based on the weighted average number of common shares outstanding during the period. Diluted netincome per common share is computed by dividing net income by the weighted average number of common and potentially dilutive common sharesoutstanding during the period. Potentially dilutive common shares of our stock result from dilutive common stock options and restricted stock units. We usethe treasury stock method to calculate the weighted-average shares used in the diluted earnings per share computation. Under the treasury stock method, theproceeds from exercise of an option, the amount of compensation cost, if any, for future service that we have not yet recognized, and the amount of estimatedtax benefits that would be recorded in paid-in capital, if any, when the option is exercised are assumed to be used to repurchase shares in the current period.The following table is a reconciliation of the numerators and denominators in the net income per common share calculations (in thousands, except percommon share data): Fiscal years ended September 30, 2017 2016 2015Numerator: Income from continuing operations$9,366 $13,478 $9,433Income (loss) from discontinued operations, after income taxes$— $3,230 $(2,845)Net income$9,366 $16,708 $6,588Denominator: Denominator for basic net income per common share — weighted average shares outstanding26,432 25,760 24,645Effect of dilutive securities: Stock options and restricted stock units667 551 582Denominator for diluted net income per common share — adjusted weighted average shares27,099 26,311 25,227 Basic net income (loss) per common share: Continuing operations$0.35 $0.52 $0.38Discontinued operations$— $0.13 $(0.12)Net income (1)$0.35 $0.65 $0.27Diluted net income (loss) per common share: Continuing operations$0.35 $0.51 $0.37Discontinued operations$— $0.12 $(0.11)Net income (1)$0.35 $0.64 $0.26(1) Earnings per share presented are calculated by line item and may not add due to the use of rounded amounts.Because their effect would be anti-dilutive at period end, certain potentially dilutive shares related to stock options to purchase common shares wereexcluded in the above computation of diluted earnings per share because the options’ exercise prices were greater than the average market price of ourcommon shares. At September 30, 2017, 2016 and 2015, such excluded stock options were 1,142,322, 1,519,691 and 3,016,911, respectively.50Table of ContentsNOTES TO CONSOLIDATED FINANCIAL STATEMENTS1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)Recent Accounting DevelopmentsAdoptedIn April 2015, FASB issued Accounting Standards Update (ASU) 2015-05, "Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40) -Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement." The new standard provides guidance to customers about whether a cloudcomputing arrangement includes a software license. If the arrangement does include a software license, the software license element of the arrangementshould be accounted for in the same manner as the acquisition of other software licenses. This guidance is effective for fiscal years, and interim periods withinthose years, beginning after December 15, 2015, with early adoption permitted. We adopted this guidance prospectively beginning with our fiscal quarterended December 31, 2016. The adoption of this standard did not have a material impact on our consolidated financial statements.In August 2014, FASB issued ASU 2014-15, "Presentation of Financial Statements - Going Concern." This guidance requires management to evaluatewhether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. These amendmentsare effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. We adopted this guidance for ourfiscal year ended September 30, 2017. The adoption of this standard did not have a material impact on our consolidated financial statements.Not Yet AdoptedIn May 2017, the Financial Accounting Standards Board (FASB) issued ASU 2017-09, "Compensation-Stock Compensation (Topic 718): Scope ofModification Accounting." ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require anentity to apply modification accounting. The amendments in this update should be applied prospectively to an award modified on or after the adoption date.This ASU is effective for annual periods and interim periods within those annual periods beginning after December 15, 2017, which for us is the first quarterending December 31, 2018. Early adoption is permitted. We do not expect the adoption of this guidance to have a material impact to our consolidatedfinancial statements.In March 2017, FASB issued ASU 2017-08, "Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on PurchasedCallable Debt Securities." The amendments in this update shorten the amortization period for certain callable debt securities that are held at a premium. Theamendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at adiscount, which would be amortized to maturity. This ASU is effective for fiscal years and interim periods within those fiscal years, beginning after December15, 2018, which for us is the first quarter ending December 31, 2019. Early adoption is permitted. We do not expect the adoption of this guidance to have amaterial impact on our consolidated financial statements.In January 2017, FASB issued ASU 2017-04, "Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." ASU 2017-04eliminates the second step in the goodwill impairment test which requires an entity to determine the implied fair value of the reporting unit’s goodwill.Instead, an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying value andrecognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, not to exceed the total amount ofgoodwill allocated to the reporting unit. The standard, which should be applied prospectively, is effective for fiscal years beginning after December 15, 2019,which for us is our fiscal year ending September 30, 2021. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2017-04 on our consolidated financial statements.In August 2016, FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments." Theamendments in this update provide guidance on eight specific cash flow issues, thereby reducing the diversity in practice in how certain transaction areclassified in the statement of cash flows. This ASU is effective for annual periods and interim periods for those annual periods beginning after December 15,2017, which for us is the first quarter ending December 31, 2018. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU2016-15 on our consolidated financial statements.51Table of ContentsNOTES TO CONSOLIDATED FINANCIAL STATEMENTS1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments."The amendments in this update replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected creditlosses. This update is intended to provide financial statement users with more decision-useful information about the expected credit losses. This ASU iseffective for annual periods and interim periods for those annual periods beginning after December 15, 2019, which for us is the first quarter ending December31, 2020. Entities may early adopt beginning after December 15, 2018. We are currently evaluating the impact of the adoption of ASU 2016-13 on ourconsolidated financial statements.In March 2016, FASB issued ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting." This update includes provisions intended tosimplify various aspects related to how share-based payments are accounted for and presented in the financial statements. This ASU is effective for annualperiods and interim periods within those annual periods beginning after December 15, 2016, which for us is the first fiscal quarter ending December 31, 2017.Early adoption is permitted. We adopted ASU 2016-09 on October 1, 2017. Upon adoption, there was no material impact on our consolidated financialstatements. Prospectively, beginning October 1, 2017, excess tax benefits and tax deficiencies will be reflected as income tax benefit or expense in ourConsolidated Statement of Operations and could result in a material impact. The extent of the excess tax benefits or tax deficiencies are subject to variationin our stock price and the timing of restricted stock unit (RSU) vestings and employee stock option exercises.In February, 2016, FASB issued ASU 2016-02, "Leases (Topic 842)", which amends the existing guidance to require lessees to recognize lease assets andlease liabilities from operating leases on the balance sheet. This ASU is effective using the modified retrospective approach for annual periods and interimperiods within those annual periods beginning after December 15, 2018, which for us is the first fiscal quarter ending December 31, 2019. Early adoption ispermitted. We are currently evaluating the impact of the adoption of ASU 2016-02 on our consolidated financial statements.In January 2016, FASB issued ASU 2016-01, "Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities."ASU 2016-01 will require equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) to bemeasured at fair value with changes in fair value recognized in net income. The amendments in this update will also simplify the impairment assessment ofequity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, eliminate the requirement forpublic business entities to disclose the method and significant assumptions used to estimate the fair value that is required to be disclosed for financialinstruments measured at amortized cost on the balance sheet and require these entities to use the exit price notion when measuring fair value of financialinstruments for disclosure purposes. This ASU would also change the presentation and disclosure requirements for financial instruments. In addition, thisASU clarifies the guidance related to valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within thosefiscal years, which for us is the first fiscal quarter ending December 31, 2018. Early adoption is permitted for financial statements of fiscal years and interimperiods that have not been issued. We are currently evaluating the impact of the adoption of ASU 2016-01.In July 2015, FASB issued ASU 2015-11, "Simplifying the Measurement of Inventory." This provision would require inventory that was previously recordedusing first-in, first-out (FIFO) to be recorded at lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course ofbusiness, less reasonably predictable costs of completion, disposal, and transportation. This guidance is effective for fiscal years beginning after December15, 2016 and interim periods within those years. We adopted this guidance beginning with our fiscal quarter ending December 31, 2017. The amendments inthis guidance should be applied prospectively with earlier application permitted as of the beginning of an interim or annual period. We do not expect theadoption of ASU 2015-11 to have a material impact on our consolidated financial statements.In May 2014, FASB issued ASU 2014-09, "Revenue from Contracts with Customers." This guidance provides a five-step analysis in determining when andhow revenue is recognized so that an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects whatit expects in exchange for the goods and services. It also requires more detailed disclosures to enable users of financial statements to understand the nature,amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB issued ASU 2015-14 "Revenuefrom Contracts with Customers (Topic 606): Deferral of the Effective Date" which approved a one-year deferral of the effective date of ASU 2014-09. As aresult of this deferral, ASU 2014-09 is effective for our fiscal year ending September 30, 2019, including interim periods within that reporting period. Inaddition, the FASB issued ASU 2016-08, ASU 2016-10 and ASU 2016-12 in March 2016, April 2016 and May 2016, respectively, to provide interpretiveclarifications on the new guidance in ASC Topic 606. We are currently working through an adoption plan and have identified our revenue streams andcompleted52Table of ContentsNOTES TO CONSOLIDATED FINANCIAL STATEMENTS1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)a preliminary analysis of how we currently account for revenue transactions compared to the revenue accounting required under the new standard. We intendto complete our adoption plan by December 31, 2017. This plan includes a review of transactions supporting each revenue stream to determine the impact ofaccounting treatment under ASC 606, evaluation of the method of adoption, and completing a rollout plan for implementation of the new standard withaffected functions in our organization. Because of the nature of the work that remains, at this time we are unable to reasonably estimate the impact ofadoption on our consolidated financial statements. We plan to adopt the new guidance beginning with our fiscal quarter ending December 31, 2018.2. ACQUISITIONSOn May 4, 2017, we announced the rebranding of our Digi Cold Chain Solutions to Digi Smart Solutions™.Acquisition of SMART Temps, LLCOn January 9, 2017, we purchased all of the outstanding interests of SMART Temps, LLC (SMART Temps), an Indiana-based provider of real-timetemperature management for pharmacies, education, and hospital settings as well as real-time temperature management for blood bank, laboratoryenvironments, restaurants, and grocery. We believe this is a complementary acquisition for us as the acquired technology will continue to be supported tofurther enhance our portfolio of products for the Solutions segment (see Note 5 to our Consolidated Financial Statements).The terms of the acquisition included an upfront cash payment together with future earn-out payments. Cash of $28.8 million (excluding cash acquired of$0.5 million) was paid at time of closing. The earn-out payments are scheduled to be paid after December 31, 2017 which is the end of the earn-out period.The cumulative amount of these earn-out payments will not exceed $7.2 million. We determined that the earn-out would be considered as part of thepurchase price consideration because there was no continuing employment requirements associated with the earn-out. The fair value of this contingentconsideration was $10,000 at the date of acquisition and zero at September 30, 2017 (see Note 8 to the Consolidated Financial Statements).The purchase price was allocated to the estimated fair value of assets acquired and liabilities assumed. The final purchase price allocation resulted in therecognition of $18.8 million of goodwill. For tax purposes, this acquisition is treated as an asset acquisition, therefore the goodwill is deductible. We believethat the acquisition resulted in the recognition of goodwill because this is a complementary acquisition for us and will provide a source of recurring revenuein a new vertically focused Solutions segment.The SMART Temps acquisition has been accounted for using the acquisition method of accounting which requires, among other things, that assets acquiredand liabilities assumed pursuant to the purchase agreement be recognized at fair value as of the acquisition date.The following table summarizes the final values of SMART Temps assets acquired and liabilities assumed as of the acquisition date (in thousands):Cash$28,754Fair value of contingent consideration on acquired business10Working capital adjustment124Total purchase price consideration$28,888 Fair value of net tangible assets acquired$761Fair value of identifiable intangible assets acquired: Purchased and core technology4,000Customer relationships4,000Trade name and trademarks711Non-compete agreements600Goodwill18,816Total$28,88853Table of ContentsNOTES TO CONSOLIDATED FINANCIAL STATEMENTS2. ACQUISITIONS (CONTINUED)Operating results for SMART Temps from January 9, 2017 forward are included in our Consolidated Statements of Operations. The Consolidated BalanceSheet as of September 30, 2017 reflects the final allocation of the purchase price to the assets acquired and liabilities assumed based on their estimated fairvalues at the date of acquisition.As of the date of acquisition, the weighted average useful life for all the identifiable intangibles listed above was 5.9 years. For purposes of determining fairvalue, the purchased and core technology identified above is assumed to have a useful life of five years, the customer relationships are assumed to haveuseful lives of seven years, the trade name and trademarks are assumed to have useful lives of five years and the non-compete agreements are assumed to haveuseful lives of five years. Useful lives for identifiable intangible assets are estimated at the time of acquisition based on the periods of time from which weexpect to derive benefits from the identifiable intangible assets.The amounts of revenue and net loss included in the Consolidated Statements of Operations from the acquisition date of January 9, 2017 were $5.5 millionand $(1.2) million, respectively. Costs directly related to the acquisition, including legal, accounting and valuation fees of approximately $0.8 million havebeen charged directly to operations and are included in general and administrative expense in our Consolidated Statements of Operations.The following consolidated pro forma information is as if the acquisition had occurred on October 1, 2015 (in thousands): Fiscal year ended September 30, 2017 2016Revenue $182,568 $207,494Income from continuing operations $8,675 $11,370Net income $8,675 $14,600Pro forma income from continuing operations and net income were both adjusted to exclude interest expense related to debt that was paid off prior toacquisition, adjust amortization to the fair value of the intangibles acquired and remove any costs that SMART Temps incurred associated with the saletransaction.Acquisition of FreshTemp, LLCOn November 1, 2016, we purchased all of the outstanding interests of FreshTemp, LLC (FreshTemp), a Pittsburgh-based provider of temperature monitoringand automated task management solutions for the food industry. We believe this is a complementary acquisition for us as the acquired technology willcontinue to be supported to create an advanced portfolio of products for the Solutions segment.The terms of the acquisition included an upfront cash payment together with future earn-out payments and a holdback amount. Cash of $1.7 million was paidat time of closing. The earn-out payments are based on revenue related to certain customer contracts entered into by June 30, 2017. The fair value of thiscontingent consideration was $1.3 million at the date of acquisition and $0.4 million at September 30, 2017 (see Note 8 to the Consolidated FinancialStatements). The final calculation date will be on June 30, 2018. The cumulative amount of these earn-out payments will not exceed $2.3 million. Wedetermined that the earn-out would be considered as part of the purchase price consideration as there was no continuing employment requirements associatedwith the earn-out. Costs directly related to the acquisition, including legal, accounting and valuation fees, of approximately $60,000 have been chargeddirectly to operations and are included in general and administrative expense in our Condensed Consolidated Statements of Operations.The purchase price was allocated to the estimated fair value of assets acquired and liabilities assumed. The purchase price allocation resulted in therecognition of $2.7 million of goodwill. For tax purposes, this acquisition is treated as an asset acquisition, therefore the goodwill is deductible. We believethat the acquisition resulted in the recognition of goodwill because this is a complementary acquisition for us and will provide a source of recurring revenuein a new vertically focused solutions business. The FreshTemp acquisition has been accounted for using the acquisition method of accounting whichrequires, among other things, that assets acquired and liabilities assumed pursuant to the purchase agreement be recognized at fair value as of the acquisitiondate.54Table of ContentsNOTES TO CONSOLIDATED FINANCIAL STATEMENTS2. ACQUISITIONS (CONTINUED)The following table summarizes the final values of FreshTemp assets acquired and liabilities assumed as of the acquisition date (in thousands):Cash$1,697Purchase price payable upon completion of diligence matters303Fair value of contingent consideration on acquired business1,300Working capital adjustment(37)Total purchase price consideration$3,263 Fair value of net tangible assets acquired$(37)Fair value of identifiable intangible assets acquired: Purchased and core technology400Customer relationships250Goodwill2,650Total$3,263Operating results for FreshTemp from November 2, 2016 forward are included in our Consolidated Statements of Operations. The Consolidated Balance Sheetas of September 30, 2017 reflects the final allocation of the purchase price to the assets acquired and liabilities assumed based on their estimated fair values atthe date of acquisition. The identifiable intangibles values and net working capital values were finalized in the second fiscal quarter of 2017.The weighted average useful life for all the identifiable intangibles listed above is 5.8 years. For purposes of determining fair value, the purchased and coretechnology identified above is assumed to have a useful life of five years and the customer relationships are assumed to have useful lives of seven years.Useful lives for identifiable intangible assets are estimated at the time of acquisition based on the periods of time from which we expect to derive benefitsfrom the identifiable intangible assets.Since the FreshTemp acquisition occurred close to the beginning of our fiscal 2017, the pro forma amounts were not materially different from actual amounts.Revenue for the year ended September 30, 2017 related to the FreshTemp acquisition was $0.5 million. As our operating costs related to the FreshTempacquisition are integrated into the Company’s operating income and related earnings per share, the separate FreshTemp amounts are not determinable forfiscal 2017. Pro forma information for fiscal 2016 was not materially different from actual amounts.Acquisition of Bluenica CorporationOn October 5, 2015, we purchased all of the outstanding stock of Bluenica Corporation (Bluenica), a company focused on temperature monitoring ofperishable goods in the food industry by using wireless sensors, which are installed in grocery and convenience stores, restaurants, and in products duringshipment and storage to ensure that quality, freshness and public health requirements are met. This acquisition formed the basis for our Solutions segment.The terms of the acquisition included an upfront cash payment together with earn-out payments. Cash of $2.9 million was paid at time of closing. The earn-out payments are scheduled to be paid in installments over a four-year period based on revenue achievement of the acquired business. Each of the earn-outpayments will be calculated based on the revenue performance of the Solutions segment for each respective earn-out period. The cumulative amount of theseearn-out payments will not exceed $11.6 million. An additional payment, not to exceed $3.5 million, may also be due depending on revenue performance.The fair value of this contingent consideration was $10.4 million at the date of acquisition and $6.0 million at September 30, 2017 (see Note 8 to theConsolidated Financial Statements). We determined that the earn-out would be considered as part of the purchase price consideration as there was nocontinuing employment requirements associated with the earn-out.The purchase price was allocated to the estimated fair value of assets acquired and liabilities assumed. The purchase price allocation resulted in therecognition of $11.0 million of goodwill. We believe that the acquisition resulted in the recognition of goodwill because this is a complementary acquisitionfor us and will provide a source of recurring revenue in a new vertically focused solutions business. Operating results for Bluenica are included in ourConsolidated Statements of Operations from October 6, 2015.55Table of ContentsNOTES TO CONSOLIDATED FINANCIAL STATEMENTS3. DISCONTINUED OPERATIONSOn October 23, 2015, we sold all the outstanding stock of our wholly owned subsidiary, Etherios to West Monroe Partners, LLC. We sold Etherios as part of astrategy to focus on providing highly reliable machine connectivity solutions for business and mission-critical application environments. Etherios wasincluded in our single operating segment prior to fiscal 2017. The terms of the sale agreement provide that West Monroe Partners LLC will pay us $3.0million on October 23, 2016 and $2.0 million on October 23, 2017. The present value of these amounts was included within the total fair value ofconsideration received. These receivable amounts are unsecured and non-interest bearing. We received $3.0 million in October 2016. The carrying value ofthe remaining receivable of $2.0 million presented on our Condensed Consolidated Balance Sheet at September 30, 2017 approximates its fair value, whichwas determined using Level 3 cash flow fair value measurement techniques. We received the second installment of $2.0 million in October 2017.Goodwill was included in the net assets of Etherios based on the relative fair value of Etherios compared to the fair value of the Company, as the Companyconsisted of a single reporting unit for goodwill impairment testing purposes at the time of disposal.As a condition to the sale agreement, we retained the operating leases in the Dallas and Chicago locations. Digi ceased using these facilities in October 2015and has sublet the Dallas location to West Monroe Partners, LLC through December 31, 2018. In January 2017, we signed an early-termination agreementalong with an immaterial payment to exit our Chicago lease. Also in connection with the sale, we assigned our San Francisco lease to West Monroe Partners,LLC.Income (loss) from discontinued operations, after income taxes, as presented in the Consolidated Statements of Operations for the twelve months endedSeptember 30, 2016 and 2015 is as follows (in thousands): Fiscal year ended September 30, 2016 2015Service revenue$891 $9,011Cost of service713 8,101Gross profit178 910Operating expenses: Sales and marketing148 1,970Research and development103 2,098General and administrative43 1,208Restructuring— 106Total operating expenses294 5,382Loss from discontinued operations, before income taxes(116) (4,472)Gain on sale of discontinued operations, before income taxes2,870 —Income (loss) from discontinued operations, before income taxes2,754 (4,472)Income tax benefit on discontinued operations(476) (1,627)Income (loss) from discontinued operations, after income taxes$3,230 $(2,845)Income tax benefit on discontinued operations for the twelve months ended September 30, 2016 was $0.5 million, which primarily represented income taxbenefits for deductible transaction costs, partially offset by a tax expense for equity awards for which we will not receive a tax deduction. For tax purposes,this transaction resulted in a capital loss, as the tax basis of the Etherios stock was higher than the book basis of the assets that were sold. Since we do notexpect to be able to utilize this capital loss in the five year carryforward period, a deferred tax asset offset by a full valuation allowance was recorded in thethird quarter of fiscal 2016 upon completion of the capital loss calculation.The following table presents amortization, depreciation and purchases of property, equipment, improvements and certain other intangible assets of thediscontinued operations related to Etherios (in thousands): Fiscal year ended September 30, 2016 2015Amortization of identifiable intangible assets $30 $483Depreciation of property, equipment and improvements $— $29Purchases of property, equipment, improvements and certain other intangible assets $— $(11)56Table of ContentsNOTES TO CONSOLIDATED FINANCIAL STATEMENTS4.

SEGMENT INFORMATION AND MAJOR CUSTOMERSAs of the fiscal quarter ended June 30, 2017, we determined that we now have two reportable operating segments for purposes of ASC 280-10-50 "SegmentReporting": (1) M2M, and (2) Solutions.This determination was made by considering both qualitative and quantitative information. The qualitative information considered during the quarter endedJune 30, 2017 included, but was not limited to, the following: the nature of the products57Table of ContentsNOTES TO CONSOLIDATED FINANCIAL STATEMENTS5. SEGMENT INFORMATION AND MAJOR CUSTOMERS (CONTINUED)and services and customers differ between the two segments, the Chief Operating Decision Maker (CODM) started reviewing both segments’ operating resultsseparately and now makes decisions about the allocation of resources, and discrete financial information is available through operating income (loss) for bothsegments. During the third quarter of fiscal 2017, the recently acquired Solutions entities financial systems were integrated allowing for the review of discretefinancial information for the Solutions segment. In addition, based on current expectations, we now expect the Solutions segment to meet the quantitativethresholds for a separate reporting segment. The financial results of the Solutions entities were previously considered not to meet the quantitative thresholdsfor a separate reporting segment. Our segments are described below:M2MOur M2M segment is composed of the following communications products and development services:•Cellular routers and gateways;•Radio frequency (RF) which include our XBee® modules as well as other RF solutions;•Embedded products include Digi Connect® and Rabbit® embedded systems on module and single board computers;•Network products, which has the highest concentration of mature products, including console and serial servers and USB connected products;•Digi Wireless Design Services;•Digi Remote Manager®; and•Support services which offers various levels of technical services for development assistance, consulting and training.SolutionsWe have formed the Solutions segment primarily through four acquisitions: the October 2015 acquisition of Bluenica, the November 2016 acquisition ofFreshTemp, the January 2017 acquisition of SMART Temps and the October 2017 acquisition of TempAlert, LLC (TempAlert). Because the acquisition ofTempAlert was subsequent to September 30, 2017, it's results are not included in our Consolidated Financial Statements (see Note 19 to our ConsolidatedFinancial Statements). Our Solutions segment offers wireless temperature and other environmental condition monitoring services as well as employee taskmanagement services. These products and services are provided to food service, transportation, education, healthcare and pharma, and industrial markets andare marketed as Digi Smart Solutions™.We measure our segment results primarily by reference to revenue and operating income (loss). Solutions revenue includes both product and service revenue.Certain costs incurred at the corporate level are allocated to our segments. These costs include information technology, employee benefits and shared facilityservices. The information technology and shared facility costs are allocated based on headcount and the employee benefits costs are allocated based oncompensation costs.Summary operating results for each of our segments were as follows (in thousands): Fiscal year ended September 30, 2017 2016 2015Revenue M2M$174,237 $202,294 $203,847Solutions7,397 711 —Total revenue$181,634 $203,005 $203,847Operating income (loss) M2M$12,804 $18,822 $10,889Solutions(3,997) (1,717) —Total operating income$8,807 $17,105 $10,889Depreciation and amortization M2M$3,575 $4,040 $5,347Solutions1,922 544 —Total depreciation and amortization$5,497 $4,584 $5,34758Table of ContentsNOTES TO CONSOLIDATED FINANCIAL STATEMENTS5.

MARKETABLE SECURITIESOur marketable securities consist of certificates of deposit, commercial paper, corporate bonds and government municipal bonds. We analyze our available-for-sale marketable securities for impairment on an ongoing basis. When we perform this analysis, we consider factors such as the length of time and extent towhich the securities have been in an unrealized loss position and the trend of any unrealized losses. We also consider whether an unrealized loss is atemporary loss or an other-than-temporary loss such as: (a) whether we have the intent to sell the security, or (b) whether it is more likely than not that we willbe required to sell the security before its anticipated recovery, or (c) permanent impairment due to bankruptcy or insolvency.In order to estimate the fair value for each security in our investment portfolio, we obtain quoted market prices and trading activity for each security whereavailable. We obtain relevant information from our investment advisor and, if warranted, also may review the financial solvency of certain security issuers. Asof September 30, 2017, 25 of our 44 securities that we held were trading below our amortized cost basis. We determined each decline in value to be temporarybased upon the above described factors. We expect to realize the fair value of these securities, plus accrued interest, either at the time of maturity or when thesecurity is sold. All of our current holdings are classified as available-for-sale marketable securities and are recorded at fair value on our consolidated balancesheet with the unrealized gains and losses recorded in accumulated other comprehensive loss. All of our current marketable securities are scheduled to maturein less than one year and our non-current marketable securities are scheduled to mature in less than two years. We received proceeds from the sale of ouravailable-for-sale marketable securities of $87.1 million, $73.7 million and $38.0 million for fiscal 2017, 2016 and 2015, respectively.At September 30, 2017 our marketable securities consisted of (in thousands): AmortizedCost (1) UnrealizedGains UnrealizedLosses Fair Value (1)Current marketable securities: Corporate bonds$28,275 $— $(20) $28,255Certificates of deposit3,756 4 — 3,760Current marketable securities32,031 4 (20) 32,015Non-current marketable securities: Certificates of deposit4,757 — (4) 4,753Total marketable securities$36,788 $4 $(24) $36,768(1)Included in amortized cost and fair value is purchased and accrued interest of $211.At September 30, 2016 our marketable securities consisted of (in thousands): AmortizedCost (1) UnrealizedGains UnrealizedLosses Fair Value (1)Current marketable securities: Corporate bonds$28,801 $— $(34) $28,767Commercial paper23,963 — (20) 23,943Certificates of deposit3,755 13 — 3,768Government municipal bonds1,904 — — 1,904Current marketable securities58,423 13 (54) 58,382Non-current marketable securities: Certificates of deposit3,505 36 — 3,541Total marketable securities$61,928 $49 $(54) $61,923(1)Included in amortized cost and fair value is purchased and accrued interest of $271.61Table of ContentsNOTES TO CONSOLIDATED FINANCIAL STATEMENTS7.

FAIR VALUE MEASUREMENTSFair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participantsas of the measurement date. This standard also establishes a hierarchy for inputs used in measuring fair value. This standard maximizes the use of observableinputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputsmarket participants would use in valuing the asset or liability based on market data obtained from independent sources. Unobservable inputs are inputs thatreflect our assumptions about the factors market participants would use in valuing the asset or liability based upon the best information available in thecircumstances.The categorization of financial assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair valuemeasurement. The hierarchy is broken down into three levels. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are notactive, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable for theasset or liability and their fair values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least onesignificant model assumption or input is unobservable. Level 3 may also include certain investment securities for which there is limited market activity or adecrease in the observability of market pricing for the investments, such that the determination of fair value requires significant judgment or estimation.Fair value is applied to financial assets such as our marketable securities, which are classified and accounted for as available-for-sale and to financialliabilities for contingent consideration. These items are stated at fair value at each reporting period using the above guidance.62Table of ContentsNOTES TO CONSOLIDATED FINANCIAL STATEMENTS8. FAIR VALUE MEASUREMENTS (CONTINUED)The following tables provide information by level for financial assets and liabilities that are measured at fair value on a recurring basis (in thousands): Fair Value Measurements at September 30, 2017 using: Total carryingvalue atSeptember 30, 2017 Quoted price inactive markets(Level 1) Significant otherobservable inputs(Level 2) Significantunobservable inputs(Level 3)Assets: Money market$39,524 $39,524 $— $—Corporate bonds28,255 — 28,255 —Certificates of deposit8,513 — 8,513 —Total assets measured at fair value$76,292 $39,524 $36,768 $—Liabilities: Contingent consideration on acquired business$6,388 $— $— $6,388Total liabilities measured at fair value$6,388 $— $— $6,388 Fair Value Measurements at September 30, 2016 using: Total carryingvalue atSeptember 30, 2016 Quoted price inactive markets(Level 1) Significant otherobservable inputs(Level 2) Significantunobservable inputs(Level 3)Assets: Money market$44,319 $44,319 $— $—Corporate bonds28,767 — 28,767 —Commercial paper23,943 — 23,943 —Certificates of deposit7,309 — 7,309 —Government municipal bonds1,904 — 1,904 —Total assets measured at fair value$106,242 $44,319 $61,923 $—Liabilities: Contingent consideration on acquired business$9,960 $— $— $9,960Total liabilities measured at fair value$9,960 $— $— $9,960Our money market funds, which have been determined to be cash equivalents, are measured at fair value using quoted market prices in active markets foridentical assets and are therefore classified as Level 1 assets. We value our Level 2 assets using inputs that are based on market indices of similar assets withinan active market. There were no transfers into or out of our Level 2 financial assets during the twelve months ended September 30, 2017.The use of different assumptions, applying different judgment to matters that are inherently subjective and changes in future market conditions could resultin different estimates of fair value of our securities or contingent consideration, currently and in the future. If market conditions deteriorate, we may incurimpairment charges for securities in our investment portfolio. We may also incur changes to our contingent consideration liability as discussed below.As discussed in Note 2, we are required to make contingent payments for our acquisitions. In connection with the Bluenica acquisition, we are required tomake contingent payments over a period of up to four years, subject to the Solutions segment achieving specified revenue thresholds. The fair value of theliability for contingent payments recognized upon acquisition was $10.4 million. In connection with the FreshTemp acquisition, we are required to make acontingent payment after June 30, 2018, for revenue related to specific customer contracts signed by June 30, 2017. The fair value of the liability recognizedupon acquisition was $1.3 million. For the SMART Temps acquisition, we are required to make a contingent payment after December 31, 2017 based onachieving specified revenue thresholds. The fair value of the liability for contingent payments recognized upon acquisition was $10,000. The fair values ofthese contingent payments was estimated by discounting to63Table of ContentsNOTES TO CONSOLIDATED FINANCIAL STATEMENTS8. FAIR VALUE MEASUREMENTS (CONTINUED)present value the probability-weighted contingent payments expected to be made. Assumptions used in these calculations include the discount rate andvarious probability factors. This liability is considered to be a Level 3 financial liability that is re-measured each reporting period as a charge or credit togeneral and administrative expense within the Consolidated Statements of Operations.The following table presents a reconciliation of the contingent consideration liability measured at fair value on a recurring basis using significantunobservable inputs (Level 3) (in thousands): Fiscal years ended September 30, 2017 2016Fair value at beginning of period $9,960 $—Purchase price contingent consideration 1,310 10,400Contingent consideration payments (518) —Change in fair value of contingent consideration (4,364) (440)Fair value at end of period $6,388 $9,960The change in fair value of contingent consideration relates to the acquisitions of Bluenica, FreshTemp and SMART Temps and is included in general andadministrative expense. The change in fair value of contingent consideration reflects our estimate of the probability of achieving the relevant targets and isdiscounted based on our estimated discount rate. We have estimated the fair value of the contingent consideration based on the probability of achieving thespecified revenue thresholds at 93.5% to 98.5% for Bluenica, between 25% and 100% for FreshTemp and 0% for SMART Temp. A significant increase(decrease) in our estimates of achieving the relevant targets could materially increase (decrease) the fair value of the contingent consideration liability.9.

We also eliminated certain employee costs in the U.S. Therestructuring is a result of a decision to consolidate our France operations to our Europe, Middle East and Africa (EMEA) headquarters in Munich. The totalrestructuring charges amounted to $2.5 million that included $2.3 million of employee costs and $0.2 million of contract termination costs during the thirdquarter of fiscal 2017. These actions resulted in an elimination of 10 positions in the U.S. and 8 positions in France. The payments associated with thesecharges are expected to be completed by the fourth quarter ending September 30, 2018.2016 RestructuringOn January 19, 2016, we approved a restructuring plan for our Digi Wireless Design Services group. This plan resulted in an elimination of 5 positions. Werecorded a restructuring charge of $0.1 million related to severance during the second quarter of fiscal 2016 and paid the majority of the severance duringthat same quarter.On November 19, 2015, we approved a restructuring plan impacting our corporate staff. The plan closed our Dortmund, Germany office and relocated certainemployees to our Munich office. We also recorded a contract termination charge as we relocated employees in our Minneapolis, Minnesota office to ourWorld Headquarters in Minnetonka, Minnesota in December 2015. We recorded a restructuring charge of $0.7 million that included $0.5 million ofseverance and $0.2 million of contract termination costs during the first quarter of fiscal 2016. This restructuring resulted in an elimination of 10 positions.The payments associated with these charges were completed in the third quarter of fiscal 2016.2015 RestructuringOn January 22, 2015, we announced the closure of our India location. The March closure resulted in the elimination of approximately 38 employees fromengineering, sales and administration. We recorded a restructuring charge of $0.4 million related to severance during the second quarter of fiscal 2015. Thepayments associated with this charge were completed during the third quarter of fiscal 2015.65Table of ContentsNOTES TO CONSOLIDATED FINANCIAL STATEMENTS11.

The majority of our federal research and development tax credits have a 20 year carryforwardperiod. The state research and development tax credits have a 15 year carryforward period. The majority of our non-U.S. net operating losses have anunlimited carryforward period. Our non-U.S. tax credit carryforwards will expire in 2032.

In addition, we filedamended income tax returns resulting in an additional domestic refund related to qualified manufacturing activities. These benefits are included within thediscrete tax benefits in the above table.During fiscal 2015, we recorded net tax benefits of $0.8 million, resulting from the reinstatement of the research and development tax credit for calendar year2014, reversal of tax reserves due to the expiration of statute of limitations from U.S. and foreign tax jurisdictions and reversal of tax reserves due to theresolution of tax audits.

INCOME TAXES (CONTINUED)The total amount of unrecognized tax benefits at September 30, 2017 that, if recognized, would affect our effective tax rate is $1.2 million. We expect that itis reasonably possible that the total amounts of unrecognized tax benefits will decrease approximately $0.1 million over the next 12 months due to theexpiration of various statutes of limitations.Of the $1.3 million of unrecognized tax benefits, $0.7 million is included in non-current income taxes payable and $0.6 million is included with non-currentdeferred tax assets on the consolidated balance sheet at September 30, 2017.We recognize interest and penalties related to income tax matters in income tax expense. During fiscal 2017 and 2016, there were insignificant amounts ofinterest and penalties related to income tax matters in income tax expense. We had accrued interest and penalties related to unrecognized tax benefits of $0.1million at September 30, 2017 and $0.2 million at September 30, 2016. These accrued interest and penalties are included in our non-current income taxespayable on our consolidated balance sheets.We file a U.S. federal income tax return and income tax returns in various states and foreign jurisdictions. With few exceptions, we are no longer subject tostate and local or non-U.S. income tax examinations by tax authorities for years before fiscal year 2013.At September 30, 2017, we had approximately $34.6 million of un-taxed accumulated undistributed foreign earnings, for which we have not accruedadditional U.S. tax. Our policy is to reinvest earnings of our foreign subsidiaries indefinitely to fund current operations and provide for future internationalexpansion opportunities, and only repatriate earnings to the extent that U.S. taxes have already been recorded. Although we have no current need torepatriate historical earnings in the form of cash to the United States, if we change our assertion from indefinitely reinvesting undistributed foreign earnings,we would have to accrue applicable taxes. The amount of any taxes and the application of any tax credits would be determined based on the income tax lawsat the time of such repatriation. Under current tax laws, we estimate the unrecognized deferred tax liability to be up to $0.6 million.12. STOCK-BASED COMPENSATIONStock-based awards were granted under the 2017 Omnibus Incentive Plan (the "2017 Plan") beginning January 30, 2017 and, prior to that, were granted underthe 2016 Omnibus Incentive Plan (the "2016 Plan"). Upon stockholder approval of the 2017 Plan, we ceased granting awards under any prior plan. Sharesremaining in the 2016 Plan were moved into the 2017 Plan. The authority to grant options under the 2017 Plan and to set other terms and conditions restswith the Compensation Committee of the Board of Directors. We also have awards outstanding under our 2014 Omnibus Plan (the "2014 Plan"), the 2013Omnibus Incentive Plan (the "2013 Plan") and the 2000 Omnibus Stock Plan, as amended and restated as of December 4, 2009 (the "2000 Plan").The 2017 Plan authorizes the issuance of up to 1,500,000 common shares in connection with awards of stock options, stock appreciation rights, restrictedstock, restricted stock units, performance-based full value awards or other stock-based awards. Eligible participants include our employees, our affiliates, non-employee directors of our Company and any consultant or advisor who is a natural person and provides services to us or our affiliates. Options that have beengranted under the 2017 Plan typically vest over a four-year period and will expire if unexercised after seven years from the date of grant. Restricted stock unitawards (RSUs) that have been granted to directors typically vest in one year. RSUs that have been granted to executives and employees typically vest inJanuary over a four-year period. Awards may be granted under the 2017 Plan until January 29, 2027. Options under the 2017 Plan can be granted as eitherincentive stock options (ISOs) or non-statutory stock options (NSOs). The exercise price of options and the grant date price of restricted stock units isdetermined by our Compensation Committee but may not be less than the fair market value of our common stock based on the closing price on the date ofgrant.

This Item 9A includes information concerning thecontrols and control evaluations referred to in those certifications.Evaluation of Disclosure Controls and ProceduresWe maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act that are designed to providereasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act) is recorded, processed, summarizedand reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to management ofthe Company, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.Management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the design and operationof our disclosure controls and procedures as of September 30, 2017. Based on their evaluation, the Chief Executive Officer and Chief Financial Officerconcluded that, as of September 30, 2017, our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d - 15(e) under the Security ExchangeAct of 1934, as amended) were effective and provide reasonable assurance on the reliability of the Company's financial reporting and the preparation of itsfinancial statements for external purposes in accordance with generally accepted accounting principles.Management’s Report on Internal Control Over Financial ReportingManagement is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f)under the Exchange Act). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability offinancial reporting and the preparation of our consolidated financial statements for external purposes in accordance with generally accepted accountingprinciples. Management, with the participation of our Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of our internal controlover financial reporting as of September 30, 2017.In making this assessment, management used the framework set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) inInternal Control - Integrated Framework (2013). Based on this assessment, management concluded that the Company's internal control over financialreporting was effective as of September 30, 2017 based on Internal Control - Integrated Framework (2013) issued by the COSO.The effectiveness of our internal control over financial reporting as of September 30, 2017 has been audited by Grant Thornton LLP, an independentregistered public accounting firm, as stated in their report, which is included herein.Remediation Efforts on the Material Weakness in Internal Control Over Financial ReportingA material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility thata material misstatement of our interim or annual financial statements will not be prevented or detected on a timely basis.As disclosed in the Company's 2016 Annual Report on Form 10-K, management concluded that our internal control over financial reporting was previouslynot effective based on the material weakness in internal control over financial reporting as we did not maintain effective controls to identify and maintainsegregation of duties between the ability to create and post manual journal entries to the general ledger system for a key accounting individual as we movedlocations at one of our subsidiaries, impacting the accuracy and completeness of all key accounts and disclosures at our German subsidiary. Specifically, theindividual was assigned system access to both prepare and post journal entries, while holding responsibility for review of certain monthly accountreconciliations, without his entries being subject to an independent review. Management has remediated this material weakness in fiscal 2017. Specifically,during the year ended September 30, 2017 we removed access to create and post journal entries from the member of the accounting team with incompatibleduties as of September 30, 2016. In addition, a thorough review of all journal entries made by the individual revealed no irregularities or errors. Although thiswas an isolated case, we enhanced our access review controls for our financial system to include a review of all employee75Table of Contentsstatus changes. We also have automated the approval process for manual journal entries to ensure that all journal entries are properly approved.Report of Independent Registered Public Accounting FirmBoard of Directors and StockholdersDigi International Inc.We have audited the internal control over financial reporting of Digi International Inc. (a Delaware corporation) and subsidiaries (the "Company") as ofSeptember 30, 2017, based on criteria established in the 2013 Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizationsof the Treadway Commission (COSO). The Company’s management is responsible for maintaining effective internal control over financial reporting and forits assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control overFinancial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require thatwe plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all materialrespects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testingand evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considerednecessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.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 consolidated financialstatements.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.In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of September 30, 2017, based oncriteria established in the 2013 Internal Control-Integrated Framework issued by COSO.We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financialstatements of the Company as of and for the year ended September 30, 2017, and our report dated November 22, 2017 expressed an unqualified opinion onthose consolidated financial statements./s/ GRANT THORNTON LLPMinneapolis, MinnesotaNovember 22, 2017Changes in Internal Control Over Financial ReportingThere have been no changes in our internal control over financial reporting during the quarterly period ended September 30, 2017 that have materiallyaffected, or are reasonably likely to materially affect, our internal control over financial reporting.ITEM 9B.
