offering. Installation, test and maintenance products are used to install, tune, maintain and repair wireless communications equipment. Products include sophisticated analysis equipment and various frequency-, voltage- and power-measuring devices, as well as an assortment of tools, hardware, GPS, safety and replacement and component parts and supplies required by service technicians. For more detailed financial information regarding our business segments for each of the past three fiscal years, see Note 910 to the Consolidated Financial Statements included in Item 8 to this Annual Report on Form 10-K for the fiscal year ended March 29, 2009.28, 2010.

        While we principally provide manufacturer brand-name products, a variety of products, which are primarily subscriber accessory products and infrastructure accessory components, are developed and offered under TESSCO owned-brands including, Wireless Solutions®, Ventev, TerraWave® and Airstream. Also, our WLAN certification training is offered under our GigaWave® trade name. We have not incurred significant research and development expenditures in any of the last three fiscal years.

        Our products are sold as part of our integrated product and supply chain solutions. Our supply chain services for all product areas are grouped under Knowledge, Configuration, Delivery and Control. Knowledge solutions include the entire suite of TESSCO publications that focus on educating the industry, including product highlights, showcases and/or comparisons, with comprehensive specifications on the products, solutions and applications that are offered and reinforced by engineering, sales and technical support, as well as hands-on training programs. Configuration services are comprised of customized product kitting, logistics management and consumer and retail merchandising and marketing, allowing the products to be delivered ready for immediate use, installation or resale. Our delivery system allows the customer to select 1-, 3- or 5-day "just-in-time" delivery, to specific delivery locations, designed to eliminate the customer's need for staging and warehousing. Our services that increase customer control include predetermined monthly pricing levels, the ability to monitor multi-site purchasing with pre-approved, customized parameters indicating who is able to order how much of which specific products, order delivery tracking, product usage tracking, history reporting and alternative financing options.

        As part of our commitment to customer service, we typically allow most customers to return most products for any reason, for credit, within 30 days of the date of purchase. Total returns and credits have been less than 3% of revenues in each of the past three fiscal years.

Table of Contents

        As of March 29, 2009,28, 2010, we offered products purchased from approximately 360420 manufacturers. A substantial portion of our inventory purchases are concentrated with a small number of vendors. In fiscal year 2009, products purchased from our largest vendor, Motorola Inc., generated approximately 11% of our revenue. Our next nine top vendors accounted for approximately 30% of our fiscal year 2009 revenues, thus resulting in revenue from2010, sales of products purchased from our top ten vendors ofgenerated approximately 41%40% of our total revenues. There were no vendors whose products sold by us accounted for 10% of more of our total revenues in fiscal year 2010. Although we do not maintain long-term supply contracts with our vendors, we believe that, for other than those products purchased by us as part of our relationship with Nokia Inc. (Nokia) as described below, alternative sources of supply are available for many of the product types we carry. The agreements and arrangements on which most of our larger vendor and customer relationships are based are of limited duration and terminable by either party upon several months or otherwise short notice.

        We supply repair and replacement materials to authorized service centers for Nokia primarily in the United States and Canada. Sales of the Nokia repair and replacement materials, that we purchase from Nokia and sell to approximately 1,300 separate and distinctor fulfill to service centers, accounted for approximately 6%3% of our total revenues in fiscal year 2009.2010. This relationship is a complete supply chain relationship and, therefore, we have no alternative sources of supply,supply. Nokia has recently notified us of their intent to terminate our repair and our purchases,replacement parts arrangement effective July 31, 2010. Accordingly, revenues and ultimately our resale of these products, are dependent upon the continuation of the Nokia relationship. In January 2009, we extended ourgross profits from this relationship with Nokia through December 2010.will cease on that date. We also sell products

other than Nokia repair and replacement materials to many of these customers. AbsentWhen this arrangement with Nokia terminates in July 2010, we wouldwill maintain the ability to sell our other products to these customers.

        We are dedicated to superior performance and quality and consistency of service in an effort to maintain and expand vendor relationships such as the Nokia arrangement, but there can be no assurance that we will continue to be successful in this regard in the future, or that competitive pressures or other events beyond our control will not have a negative impact on our ability to maintain these relationships or to continue to derive revenues from these relationships.

Customers

        Our customer base consists of commercial customers and consumers, which accounted for approximately 98%97% and 2%3%, respectively, of fiscal year 20092010 revenues. Commercial customers share the characteristic that they are organizations that design, install, operate, repair or sell some type of wireless communications system and/or products. Beginning in fiscal year 2008, we have categorizedWe categorize our commercial customers into three different categories: 1) public carriers and network operators, 2) resellers and 3) self-maintained users (SMUs) and governments, which accounted for approximately 13%, 60%64% and 25%20%, respectively, of fiscal year 20092010 revenues.

        Public carriers and network operators are system operators that are generally responsible for building and maintaining the public infrastructure system and providing airtime service to individual subscribers.

        Resellers include dealers and resellers that sell, install and/or service cellular telephone, wireless networking, broadband and two-way radio communications equipment primarily for the enterprise market, and to a lesser extent, the consumer market.markets. These resellers include local and national value-added resellers and retailers.

        SMUs and government customers include commercial entities, major utilities, transportation companies, installation centers, federal agencies and state and local governments.

        Consumers place orders for devices and related accessories via telephone and the Internet primarily through our affinity-marketing programs. Under these programs, we collaborate with our affinity-marketing clients to market to their customers under their brands. In many cases, we act as the merchant on behalf of the affinity-marketing client, interfacing with the customer, accepting the order, shipping from our inventory and collecting payment. Our affinity-marketing programs create a high level of customer service and supplementary income for the client through revenue share payments. In

Table of Contents

addition to our affinity programs, we maintain our own internally developed consumer Web site, YourWirelessSource.com™, which offers cellular phone accessories and other complementary consumer wireless products.

        Our largest customer relationship, AT&T Mobility, (formerly Cingular Wireless), a top tier cellular carrier purchasing phone accessories, accounted for approximately 22%30% of our revenues during fiscal year 2009.2010. Our next nine largest customer relationships accounted for 9%10% of our total revenues during fiscal year 2009,2010, and therefore, our top ten customer relationships totaled 31%40% of our total revenues.

        Although we currently service customers in over 100 countries, approximately 96%97% of our sales have been made to customers in the United States during each of the past three fiscal years. Due to our diverse product segments and our wide customer base, our business is not significantly affected by seasonality in the aggregate. However, sales to our retailers generally peak in our second and third quarters in preparation for the winter holiday season. Also, our network infrastructure sales are typically affected by weather conditions in the United States, especially in our fourth quarter.

Method of Operation

        We believe that we have developed a highly integrated, technologically advanced and efficient method of operation based on the following key tenets:

•

Understanding and anticipating customers' needs and building solutions by cultivating lasting relationships;



•

Allowing customers to make the best decisions by delivering product knowledge, not just information, through our knowledge tools, includingThe Wireless Guide®, and TESSCO.com®, our Internet-based Solution and Transaction System;



•

Responding to what we refer to as "the moments of truth" by providing customers with sales, service and technical support, 24 hours a day, 7 days a week, 365 days a year;



•

Providing customers what they need, when and where they need it by delivering integrated product and supply chain solutions; and



•

Helping customers enhance their operations by providing real-time order tracking and performance measurement.

        We operate as a team of teams structured to enhance marketing innovation, customer focus and operational excellence and consist of these integrated units:

        Market Development and Sales:    In order to meet the needs of a dynamic and diverse marketplace, sales and marketing activities are organized on an end-market basis. Sales teams are focused on: public carrier and network operator (e.g., carriers, infrastructure site owners, program site managers, contractors and integrators); SMUs and governments (e.g., self-maintained users, governments, manufacturers, repair centers); resellers (e.g. retailers, dealers and value-added resellers); and consumers (e.g., affinity programs, Web store programs and fulfillment and consumer services). This organization allows for the development of unique product and solution offerings to meet the needs of our diverse customer base.

        We attempt to understand and anticipate customers' needs and to build solutions by cultivating lasting relationships. Our commercial customer database contains detailed information on approximately 280,000 existing and potential customers, including the names of key personnel, past contacts, inquiries, and buying and credit histories. This extensive customer database enables us to identify and target potential customers and to market specific products to these targeted customers. Potential customers are identified through their responses to TESSCO.com®, direct-marketing materials, advertisements in trade journals and industry trade shows, as well as through referrals from

Table of Contents

other TESSCO customers and vendors. Customer relationship representatives pursue these customer inquiries through distribution of our Knowledge Tools and through phone contact, electronic communications and field visits. The information technology system tracks potential customer identification from the initial marketing effort through the establishment and development of a purchasing relationship. Once a customer relationship is established, we carefully analyze purchasing patterns and identify opportunities to encourage customers to make more frequent purchases of a broader array of products. Scheduled contacts are made to each regularly purchasing customer for the purpose of information dissemination, order generation, database maintenance and the overall enhancement of the business relationship. The process is aimed at the attraction of prospects to TESSCO, the conversion of these prospects to buying customers, and the ultimate migration to loyal, total-source monthly buyers.

        Solutions Development and Marketing:    We actively monitor advances in technologies and industry trends, both through market research and continual customer and manufacturer interaction, and continue to enhance our product offering as new wireless communications products and technologies are developed.

Table of Contents

        In addition to determining the product offering, our product and solutions development teams provide the technical foundation for both customers and our personnel. The Wireless Product Knowledge System (WPKS) is continually updated to add new products and additional technical information in response to manufacturer specification changes and customer inquiries. WPKS contains detailed information on each SKU offered, including full product descriptions, category classifications, technical specifications, illustrations, product cost, pricing and delivery information, alternative and associated products, and purchase and sales histories. This information is available on a real-time basis to all of our personnel for product development, procurement, technical support, cataloging and marketing.

        As a thought leader in the wireless industry, TESSCO's marketing materials are used for both educating the industry and for promoting TESSCO's value. We utilize our WPKS to develop both broad-based and customized product information materials. These materials are designed to encourage both existing and potential customers to realize the value we provide in their product and supply chain decisions. These Knowledge Tools are an integrated suite of informational print and electronic media. They include:The Wireless Guide®Guide®, our product catalogue which is distributed annually to more than 75,000our current and prospective buyers;The Wireless Journal®Journal®, a trade journal with a bi-monthly circulation of approximately 80,000, which is designed to introduce the reader to our capabilities and product offerings, and contains information on significant industry trends and product reviews;The Wireless Update®Update®, which is emailed monthly to more than 107,000120,000 different individuals, and is uniquely produced for various portions of our customer base; theThe Wireless Bulletin® family, of Wireless Bulletins includingThe Wireless Bulletin for Accessories for Handsets & Music Devices, The Wireless Bulletin for Installation, Test & Maintenance Products, The Wireless Bulletin for Security & Surveillance, The Wireless Bulletin for Site Planning, The Wireless Bulletin for Training, andThe Wireless Bulletin for Wireless Networking Solutions, which are distributed throughout different times of the year and have an annual circulation of approximately 445,000;The Wireless Guide At-a-Glance, which is annually distributed to more than 100,000 individuals,200,000; Technical Application Notes, Application Drawings and White Papers, which provide in-depth planning and installation instructions and diagrams; Tech Tips, which offer suggestions and ideas from TESSCO customers; and TESSCO.com®. In addition, TESSCO publishes online, Web-browser-enabled, companion versions of its many printed publications, including the newWireless Guide Online which is updated three times each year.

        Our Knowledge Tools empower our customers to make better decisions by delivering product knowledge, rather than just information. These tools also afford our manufacturers the opportunity to develop their brands and to promote their products to a broad and diverse customer base.

        Procurement and Inventory Management:    Our product management and purchasing system aims to provide customers with a total source of broad and deep product availability, while maximizing our return on our inventory investment.

        We use our information technology system to monitor and manage our inventory. Historical sales results, sales projections and information regarding vendor lead times are all used to determine appropriate inventory levels. The information technology system also provides early warning reports regarding upcoming inventory requirements. As of March 29, 200928, 2010 and March 30, 2008,29, 2009, we had an immaterial level of backlog orders. Most backlog orders as of March 29, 2009,28, 2010, are expected to be filled within 90 days of fiscal year-end. For the fiscal years ended March 29, 200928, 2010 and March 30, 2008,29, 2009, inventory write-offs, excluding purchases from vendors for whom we hold goods on consignment, were 0.7%0.6% and 1.2%0.7% of total purchases, respectively. In many cases, we have been able to return slow-moving inventory to our vendors pursuant to stock rotation agreements. Inventory turns for fiscal years 2010 and 2009 were 9.8 and 2008 were 8.4, and 9.3, respectively. This decreaseincrease is largely due to lowerhigher overall sales in fiscal year 20092010, including higher sales to our large tier one carrier customer, as compared to fiscal year 2008.2009.

Table of Contents

        Customer Support and Order Entry:    Our customer support teams are responsible for responding to what we refer to as "the moments of truth" by delivering sales and customer support services through an effective and efficient transaction system. We also continually monitor our customer service performance through report cards included withsent for each product delivery, customer surveys and regular interaction with customers. By combining our broad product offering with a commitment to superior customer service, we seek to reduce a customer's overall procurement costs by enabling the customer to consolidate the number of suppliers from which it obtains products, while also reducing the customer's need to maintain high inventory levels.

        Our information technology system provides detailed information on every customer account, including recent inquiries, buying and credit histories, separate buying locations within a customer account and contact diaries for key personnel, as well as detailed product information, including technical, product availability and pricing information. The information technology system increases sales productivity by enabling any customer support representative to provide any customer with personalized service and also allows non-technical personnel to provide a high level of technical product information and order assistance.

        We believe that our commitment to providing prompt, friendly and efficient customer service before, during and after the sale enables us to maximize sales, customer satisfaction and customer retention. The average number of commercial customers decreased slightlyincreased from 12,300 in fiscal year 2008 to 12,200 in fiscal year 2009.2009 to 12,400 in fiscal year 2010. An average of 1,500800 consumer end-users were served per month in fiscal year 20092010 as compared with 3,2001,500 in fiscal year 2008.2009. This decline in consumers is due to changes in relationships with some of our affinity partners.

        Fulfillment and Distribution:    Orders are received at our Hunt Valley, Maryland, Reno, Nevada and San Antonio, Texas customer sales support centers. As orders are received, customer representatives have access to technical information, alternative and complementary product selections, product availability and pricing information, as well as customer purchasing and credit histories and recent inquiry summaries. An automated materials-handling system, which is integrated with the product planning and procurement system, allows us to ensure inventory control, minimize multiple

Table of Contents

product shipments to complete an order and limit inventory duplication. Bar-coded labels are applied to every product, allowing distribution center personnel to utilize radio frequency scanners to locate products, fill orders and update inventory records in real-time, thus reducing overhead associated with the distribution functions. Orders are delivered to customers by a variety of freight line and parcel transportation carrier partners with whom we contract.

        Performance and Delivery Guarantee ("PDG") charges are generally calculated on the basis of the weight of the products ordered and on the delivery service requested, not distance to the customer. We believe that this approach combined with our Performance and Delivery Guarantee, which emphasizes on-time delivery instead of shipment dates, enables customers to minimize their inventories and reduce their overall procurement costs, thereby encouraging them to make us their total source supplier.

        Information Technology:    Critical to the success of our operations is our information technology system. We have made substantial investments in the development of this system, which integrates cataloging, marketing, sales, fulfillment, inventory control and purchasing, financial control and internal and external communications. The information technology system includes highly developed customer and product databases and is integrated with our Configuration, Fulfillment and Delivery system. The information contained in the system is available on a real-time basis to all of our employees and is utilized in every area of our operations.

        We develop, construct, maintain and host several Web sites for certain affinity partners. These sites include control capabilities, including partner branding, independent landing pages and URLs, product filtering and purchase authorization limits that allow us to seamlessly interact with the customer, fulfill online orders and provide required information to these affinity partners.

Table of Contents

        We believe that we have been successful to date in pursuing a highly integrated, technologically advanced and efficient method of operations; however, disruption to our day-to-day operations, including failure of our information technology system, distribution system, or freight carrier interruption, could impair our ability to receive and process orders or to ship products in a timely and cost-efficient manner.

Acquisitions

        In July 2007, we acquired the net assets and business of NetForce Solutions, Inc. (NetForce), a provider of technical and sales training solutions to wireless, telecommunications, and networking industries. The purchase included substantially all of the non-cash business assets of NetForce for a cash payment of approximately $659,500.

        In April 2006, we acquired the non-cash assets and businesses of TerraWave Solutions, Ltd. (TerraWave) and its commonly owned affiliate, GigaWave Technologies, Ltd. (GigaWave) for an initial cash payment of approximately $3.9 million, and potential additional cash earn-out payment obligations accruing over athe four-year period ending in April 2010, contingent on the achievement by the TerraWave/GigaWave business unit post-acquisition of certain minimum earnings thresholds. OfWe expect the $3.9 million cash amount paid at closing, $1.5 million was a non-refundable prepayment against future earn-out obligations. To the extent that the minimum earnings thresholds are not achieved, we will not be able to apply the remainder of this prepayment. The maximum amount of contingent futuretotal purchase price, including earn-out payments, not yet applied as of March 29, 2009 (assuming that all remaining performance thresholds are fully met, and after subtracting the remaining portion of the $1.5 million prepayment) is $12.0to be approximately $12.7 million.

        The TerraWave business designs, configures and offers Wi-Fi products and accessories, manymost of which are branded under TerraWave's private label. Some of the TerraWave-branded products are sold with products of Cisco Systems under Cisco's Strategic Technology Integrator program. The GigaWave business provides curriculum development and hands-on, instructor-led training courses for the Wireless Local Area Network (WLAN) industry. GigaWave develops and delivers wireless networking courseware for Cisco Systems, allowing IT professionals to obtain Cisco Wireless Certifications.

Competition

        The wireless communications distribution industry is competitive and fragmented, and is comprised of distributors, such as Hutton Communications, Brightpoint, Embarq Logistics, Westcon, Comstor, Tech Data, Ingram Micro, Superior Communications, Site Pro 1, Wincomm, Talley Communications and Alliance Semiconductor. In addition, many manufacturers sell and fulfill directly to customers. Barriers to entry for distributors are relatively low, particularly in the mobile devices and accessory market, and the risk of new competitors entering the market is high. In addition, the agreements or arrangements with our customers or vendors looking to us for product and supply chain solutions, are typically of limited duration and are terminable by either party upon several months or otherwise short notice. Accordingly, our ability to maintain these relationships is subject to competitive pressures and challenges. We believe, however, that our strength in service, the breadth and depth of our product offering, our information technology system, and our large customer base and purchasing relationships with approximately 360420 manufacturers, provide us with a significant competitive advantage over new entrants to the market. Some of our current competitors have substantially greater capital resources and sales and distribution capabilities than we do. In response to competitive pressures from any of our current or future competitors, we may be required to lower selling prices in order to maintain or increase market share, and such measures could adversely affect our operating results.

        Continuing changes in the wireless communications industry, including risks associated with conflicting technology, changes in technology, inventory obsolescence, and consolidation among wireless carriers, could adversely affect future operating results.

        We believe that the principal competitive factors in supplying products to the wireless communications industry are the quality and consistency of customer service, particularly timely delivery of complete orders, breadth and quality of products offered and total procurement costs to the customer. We believe that we compete favorably with respect to each of these factors. In particular, we

Table of Contents

believe we differentiate ourselves from our competitors based on the breadth of our product offering, our ability to quickly provide products and supply chain solutions in response to customer demand and technological advances, our knowledge and expertise in wireless technologies and the wireless marketplace, the level of our customer service and the reliability of our order fulfillment process.

Intellectual Property

        We seek to protect our intellectual property through a combination of trademarks, service marks, confidentiality agreements, trade secret protection and, if and when appropriate, patent protection. Thus far, we have generally sought to protect our intellectual property, including our product data and information, customer information and information technology systems, through trademark filings and nondisclosure, confidentiality and trade secret agreements. We typically require our employees, consultants and others having access to our technology to sign confidentiality and nondisclosure agreements. There can be no assurance that these confidentiality and nondisclosure agreements will be honored, or whether they can be fully enforced, or that other entities may not independently develop systems, technologies or information similar to that on which we rely.

        TESSCO Communications Incorporated, a wholly-owned subsidiary of TESSCO Technologies Incorporated, maintains a number of registered trademarks and service marks in connection with our business activities, including "TESSCO®," "Delivering What You Need...When and Where You Need It®," "Your Total Source®," "Your Virtual Inventory®," "Your Wireless Success. Nothing Less®," "The Wireless Journal®Journal®," "Wireless Solutions®," "The Wireless Guide®," "The Wireless Update®," "The Wireless Bulletin®," "The Vital Link to a Wireless World®," "Transmitter®," "T-Flash®," "Techdirect®," "A Simple Way of Doing Business®," "TerraWave Solutions®," and "GigaWave Technologies®." Our general policy is to file for trademark and service mark protection for each of our trademarks and trade names and to enforce our rights against any infringement.

        Although we currently hold no patents, we intend, if and when appropriate, to seek patent protection for patentable technology. The ability to obtain patent protection involves complex legal and factual questions. Others may obtain patent protection for technologies that are important to our business, and as a result, our business may be adversely affected. In response to patents of others, we may need to license the right to use technology patented by others, or in the event that a license cannot be obtained, to design our systems around the patents of others.

Environmental Regulation

        We are subject to various laws and governmental regulations concerning environmental matters and employee safety and health in the United States. We are also subject to regulation by the Occupational Safety and Health Administration concerning employee safety and health matters. Compliance with these federal, state and local laws and regulations related to protection of the environment and employee safety and health has had no material effect on our business. There were no material capital expenditures for environmental projects in fiscal year 20092010 and there are no material expenditures planned for such purposes in fiscal year 2010.2011.

Item 1A.    Risk Factors.

        We are not able to identify or control all circumstances that could occur in the future that may adversely affect our business and operating results. The following are certain risk factors that could adversely affect our business, financial position and results of operations. These risk factors and others described in this Annual Report on Form 10-K should be considered in connection with evaluating the forward-looking statements contained in this Annual Report on Form 10-K because these factors could cause the actual results and conditions to differ materially from those projected in the forward-looking statements. Additional risks and uncertainties that management is not aware of or focused on, or that management currently deems immaterial may also adversely affect our business, financial position and results of operations. If our business, financial position and results of operations are adversely affected by any of these or other adverse events, our stock price would also likely be adversely affected.

RISKS RELATING TO OUR BUSINESS

We face significant competition in the wireless communications distribution industry.

        The wireless communications distribution industry is competitive and fragmented, and is comprised of several national distributors, as well as numerous regional distributors. In addition, many manufacturers sell and fulfill directly to customers. Barriers to entry for distributors are relatively low, particularly in the mobile devices and accessory market, and the risk of new competitors entering the market is high. Some of our current competitors have substantially greater capital resources and sales and distribution capabilities than we do. In response to competitive pressures from any of our current or future competitors, we may be required to lower selling prices in order to maintain or increase market share, and such measures could adversely affect our operating results.

The lossWe typically purchase and sell our products and services on the basis of keyindividual sales or purchase orders, and even in those cases where we have standing agreements or arrangements with our customers and vendors, those agreements and arrangements typically contain no purchase or suppliers could have a material adverse affect on our business, financial positionsale obligations and results of operations.are otherwise terminable by either party upon several months or otherwise short notice.

        We do not maintain long-term supply contractsOur sales to customers and our purchases from vendors are largely governed by individual sales or purchase orders, so there is no guarantee of future business. In some cases, we have formal agreements or arrangements with oursignificant customers or vendors, but they are largely administrative in nature and are terminable by either party upon several months or suppliers.otherwise short notice, and they typically contain no purchase or sale obligations. If our vendors or suppliers refuse to, or for any reason are unable to supply products to us, and if we are not able to procure those products from alternative sources, we may not be able to maintain appropriate inventory levels andto meet customer demand and our business, financial position and results of operations would be adversely affected. Similarly, if customers decide to make purchases from other sources, experiences significant changes in demand internally or from their own customer bases, becomes financially unstable, or are acquired by another company, our ability to generate revenues from these customers may be significantly affected, resulting in an adverse affect on our financial position and results of operations.

The loss or any change in the business habits of key customers or vendors, including AT&T Mobility, may have a material adverse affect on our financial position and results of operations.

        Because our standing arrangements and agreements with our customers and vendors typically contain no purchase or sale obligations and are terminable by either party upon several months or otherwise relatively short notice, we are subject to significant risks associated with the loss or change at any time in the business habits and financial condition of key customers or vendors. In fiscal year 2010, sales to our largest customer relationship, AT&T Mobility, a top tier cellular carrier purchasing phone accessories, accounted for approximately 30% of total revenues. Our relationship with AT&T Mobility,

Table of Contents

or sales pursuant to this relationship, could terminate at any time with little or no notice. As a result, and unless and until replaced from other sources, our revenue would substantially decrease and our stock price would likely decline. We have experienced the loss and changes in the business habits of significant customer and vendor relationships in the past and expect to do so in the future. It is the nature of the business. Over the past decade, however, we have generally been successful in replacing significant customer and vendor relationships when lost, and notwithstanding these losses, our revenues over this period have generally increased. There can be no assurance, however, that we will be successful in replacing any of our current relationships if and when lost, or in the event of a substantial reduction in revenues from any such relationship, including our relationship with AT&T Mobility. Unless and until replaced, any such loss will likely have a material adverse affect on our business, results of operations and financial condition, and our stock price will likely be adversely affected.

Our business depends on the continued tendency of wireless equipment manufacturers and network operators to outsource aspects of their business to us in the future.

        We provide functions such as distribution, inventory management, fulfillment, customized packaging, e-commerce solutions, and other outsourced services for many wireless manufacturers and network operators. Certain wireless equipment manufacturers and network operators have elected, and others may elect, to undertake these services internally. Additionally, our customer service levels, industry consolidation, competition, deregulation, technological changes or other developments could reduce the degree to which members of the global wireless industry rely on outsourced logistic services such as the services we provide. Any significant change in the market for our outsourced services could have a material adverse effect on our business. Our outsourced services are generally provided under short-term contractual arrangements. The failure to obtain renewals or otherwise maintain these agreements on terms, including price, consistent with our current terms could have a material adverse effect on our business.

We require substantial capital to operate, and the inability to obtain financing on favorable terms will adversely impact our business, financial position and results of operations.

        Our business requires substantial capital to operate and to finance accounts receivable and product inventory that are not financed by trade creditors. We have historically relied upon cash generated from

Table of Contents

operations, revolving credit facilities and trade credit from our vendors to satisfy our capital needs and finance growth. As the financial markets change and new regulations come into effect, the cost of acquiring financing and the methods of financing may change. Changes in our credit rating or other market factors may increase our interest expense or other costs of capital, or capital may not be available to us on competitive terms to fund our working capital needs. Our credit facilities and long-term debt arrangements are of specified terms and contain various financial and other covenants that may limit our ability to borrow or limit our flexibility in responding to business conditions. While we generally expect to either extend or replace our credit facilities at term expirations, there can be no assurances that we will be able to do so on favorable terms, or at all. The inability to maintain or when necessary obtain adequate sources of financing could have an adverse affect on our business. Our current revolving credit facility expires in May 2010.2012. Some of our existing financing instruments involve variable rate debt, thus exposing us to risk of fluctuations in interest rates. Such fluctuations in interest rates could have an adverse affect on our business, financial position and results of operations. We have and may also in the future use interest rate swaps in an effort to achieve a desired proportion of fixed and variable rate debt. We utilize these derivative financial instruments to enhance our ability to manage risk, including interest rate exposures that exist as part of our ongoing business operations. However, our use of these instruments may not effectively limit or eliminate our exposure to a decline in operating results due to changes in interest rates.

Table of Contents

The current global financial crisis may have significant effects on our customers and suppliers that could result in material adverse effects on our business, operating results, and stock price.

        The current global financial crisis—which has included, among other things, significant reductions in available capital and liquidity from banks and other providers of credit, substantial reductions and/or fluctuations in equity and currency values worldwide, significant decreases in consumer confidence and consumer and business spending, rising unemployment and concerns that the worldwide economy may enter into a prolonged recessionary period—may materially adversely affect our customers' access to capital or willingness to spend capital on our products, and/or their levels of cash liquidity with which to pay for our products. In addition, the current global financial crisis may materially adversely affect our suppliers' access to capital and liquidity, which may in turn adversely impact their ability to maintain inventories, production levels, and/or product quality, or cause them to raise prices or lower production levels, or result in their ceasing operation. Further, with respect to our $50 million unsecured revolving credit facility discussed under "Liquidity and Capital Resources" in Item 7 of this Form 10-K, if the global financial crisis continues to adversely impact SunTrust Bank and/or Wachovia Bank, National Association, or if the global financial crisis should be prolonged and affect our ability to extend or replace this revolving credit facility upon expiration in May 2010, our access to borrowings, and accordingly our business, could be materially adversely affected.

        The potential effects of the current global financial crisis are difficult to forecast and mitigate. As a consequence, our operating results for a particular period may be more difficult to predict. Any of the foregoing effects could have a material adverse effect on our business, results of operations and financial condition, and could adversely affect our stock price.

Our ability to borrow funds under our credit agreement could be constrained by the level of eligible receivables and inventory.

        Our borrowing availability under our existing revolving credit facility is limited to certain amounts of eligible accounts receivable and inventory. If the value of eligible accounts receivable and inventory were to decrease significantly, the amount available for borrowing under the facility could decrease.

We may be unable to successfully execute our merchandising and marketing strategic initiatives.

        We are focusing our sales and marketing efforts and initiatives to maximize sales. If we fail to successfully execute these initiatives, our business, financial position and results of operations could be adversely affected.

The loss of key customers will have a material adverse affect on our business, financial position and results of operations.

        Most of our agreements with significant customers are terminable by either party upon several months or otherwise short notice. Customers typically do not have an obligation to make purchases

Table of Contents

from us. In the event a significant customer decides to make its purchases from another source, experiences a significant change in demand internally or from its own customer base, becomes financially unstable, or is acquired by another company, our ability to generate revenues from these customers may be significantly affected, resulting in an adverse affect on our business, financial position and results of operations. In fiscal year 2009, sales to our largest customer relationship, AT&T Mobility, a top tier cellular carrier purchasing phone accessories, accounted for approximately 22% of total revenues.

The telecommunications products marketplace is dynamic and challenging because of the continued introduction of new products and services.

        We must constantly introduce new products, services and product features to meet competitive pressures. We may be unable to timely change our existing merchandise sales mix in order to meet these competitive pressures, which may result in increased inventory costs, inventory write-offs or loss of market share.

        Additionally, our inventory may also lose value due to price changes made by our significant vendors, in cases where our arrangements with these vendors do not provide for inventory price protection, or in cases that the vendor is unable or unwilling to provide these protections.

Consolidation among wireless service carriers could result in the loss of significant customers.

        The wireless service carrier industry has experienced significant consolidation in recent years. If any of our significant customers or partners are acquired or consolidate with others carriers, or are otherwise involved in any significant transaction that results in them ceasing to do business with us, or significantly reducing the level of business that they do with us, our revenues from those customers could be significantly affected, possibly resulting in an adverse affect on our business, financial position and results of operations.

Table of Contents

The failure of our information systems or inability to upgrade them could have a material adverse affect on our business, financial position and results of operations.

        We are highly dependent upon our internal computer and telecommunication systems to operate our business. There can be no assurance that our information systems will not fail or experience disruptions, that we will be able to attract and retain qualified personnel necessary for the operation of such systems, that we will be able to expand and improve our information systems, that we will be able to convert to new systems efficiently, or that we will be able to integrate new programs effectively with our existing programs. Any of such problems, or any significant damage or destruction of these systems, could have an adverse affect on our business, financial position and results of operations.

We depend heavily on e-commerce, and website security breaches or Internet disruptions could have a material adverse affect on our business, financial position and results of operations.

        We rely on the Internet (including TESSCO.com® and other affinity websites) for a significant percentage of our orders and information exchanges with our customers. The Internet and individual websites have experienced a number of disruptions and slowdowns, some of which were caused by organized attacks. In addition, some websites have experienced security breakdowns. There can be no assurances that our website will not experience any material breakdowns, disruptions or breaches in security. If we were to experience a security breakdown, disruption or breach that compromised sensitive information, this could harm our relationship with our customers or suppliers. Disruption of our website or the Internet in general could impair our order processing or more generally prevent our customers and suppliers from accessing information or placing orders. This could have an adverse affect on our business, financial position and results of operations.

Table of Contents

The inability to hire or retain certain key professionals, management and staff could adversely affect our business, financial condition and results of operations.

        The nature of our business includes (but is not limited to) a high volume of transactions, business complexity, wide geographical coverage, and broad scope of products, suppliers, and customers. In order to compete, we must attract, retain and motivate executives and other key employees, including those in managerial, technical, sales, marketing and support positions. Hiring and retaining qualified executives, information technology and business generation personnel are critical to our business. While our success depends upon the skills of many of our personnel, we are particularly dependent upon the skills and leadership of Robert B. Barnhill, Jr., our chairman, president and chief executive officer. The loss of any of these individuals, and particularly Mr. Barnhill, could have a material adverse affect on our business, financial position and results of operations.

        To attract, retain and motivate qualified employees, we rely heavily on stock-based incentive awards such as Performance Stock Units (PSUs). If performance targets associated with these PSUs are not met, or the value of such stock awards does not appreciate as measured by the performance of the price of our common stock and/or if our other stock-based compensation otherwise ceases to be viewed as a valuable benefit, our ability to attract, retain and motivate our employees could be adversely impacted, which could negatively affect our business, financial position and results of operations and/or require us to increase the amount we spend on cash and other forms of compensation. Our ability to issue PSUs is also limited by the provisions of and our available shares in our current and/or future stock incentive plans, which may be subject to shareholder approval.

The damage or destruction of any of our principal distribution or administrative facilities could materially adversely impact our business, financial position and results of operations.

        If any of our distribution centers in Hunt Valley, Maryland or Reno, Nevada, were to be significantly damaged or destroyed, we could suffer a loss of product inventory and our ability to

Table of Contents

conduct our business in the ordinary course could be materially and adversely affected. Similarly, if our office locations in Hunt Valley, Maryland, Nevada or San Antonio, Texas were to be significantly damaged or destroyed, our ability to conduct marketing, sales and other corporate activities in the ordinary course could be adversely affected.

We depend on third parties to manufacture products that we distribute and, accordingly, rely on their quality control procedures.

        Product manufacturers typically provide limited warranties directly to the end consumer or to us, which we generally pass through to our customers. If a product we distribute for a manufacturer has quality or performance problems, our ability to provide products to our customers could be disrupted, which could adversely affect our operations.

Our future operating results depend on our ability to purchase a sufficient amount of finished goods and bulk inventory to meet the demands of our customers.

        Our ability to meet customers' demands depends, in part, on our ability to obtain timely and adequate delivery of inventory from our suppliers. We have experienced shortages in the past that have negatively impacted our operations. Although we work closely with our suppliers to avoid these types of shortages, there can be no assurances that we will not encounter these problems in the future. Furthermore, certain of our components are available only from a single source or limited sources. We may not be able to diversify sources in a timely manner. A reduction or interruption in supplies or a significant increase in the price of supplies could have a negative impact on our results of operations or financial condition.

If our business does not perform well, or if we otherwise experience decline in the fair values of a portion or all of our business, we may be required to recognize impairments of our intangible or other long-lived assets, which could adversely affect our results of operations or financial condition.

        Goodwill and indefinite lived intangible assets are initially recorded at fair value and are not amortized, but are reviewed for impairment at least annually or more frequently if impairment indicators are present. In assessing the recoverability of goodwill and indefinite lived intangible assets, we make estimates and assumptions about sales, operating margin, growth rates and discount rates based on our budgets, business plans, economic projections, anticipated future cash flows and marketplace data. There are inherent uncertainties related to these factors and management's judgment in applying these factors. Goodwill and indefinite lived intangible asset valuations have been calculated using an income approach based on the present value of future cash flows of each reporting unit. We could be required to evaluate the recoverability of goodwill and indefinite lived intangible assets prior

Table of Contents

to the annual assessment if we experience disruptions to the business, unexpected significant declines in operating results, divestiture of a significant component of our business or sustained market capitalization declines. These types of events and the resulting analyses could result in goodwill and indefinite lived intangible asset impairment charges in the future. Impairment charges could substantially affect our financial results in the periods of such charges. In addition, impairment charges would negatively impact our financial ratios and could limit our ability to obtain financing in the future. As of March 29, 2009,28, 2010, we had $7.4$9.9 million of goodwill and indefinite lived intangible assets, which represented approximately 6.2%6.5% of total assets.

        Deferred income tax represents the tax effect of the differences between the book and tax bases of assets and liabilities. Deferred tax assets are assessed periodically by management to determine if they are realizable. Factors in management's determination include the performance of the business, projections of future taxable income, and the feasibility of ongoing tax planning strategies. If based on available information, it is more likely than not that the deferred income tax asset will not be realized

Table of Contents

then a valuation allowance must be established with a corresponding charge to net income. Such charges could have a material adverse effect on our results of operations or financial condition.

        Our future results of operations may be impacted by the prolonged weakness in the current economic environment which may result in an impairment of any goodwill recorded and/or other long lived assets or the recording of a valuation allowance on our deferred tax assets, which could adversely affect our results of operations or financial condition.

We rely on trademark filings and confidentiality agreements to protect our intellectual property rights.

        In an effort to protect our intellectual property, including our product data, customer information and information technology systems, through trademark filings and nondisclosure, confidentiality and trade secret agreements, we typically require our employees, consultants and others having access to this information or our technology to execute confidentiality and non-disclosure agreements. These agreements, however, may not provide us with adequate protection against improper use or disclosure of confidential information, and these agreements may be breached. A breach of confidentiality could adversely affect our business. In addition, in some situations, these agreements may conflict with, or be subject to, the rights of third parties with whom our employees, consultants and others have previous employment or consulting relationships. Also, others may independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets. Adequate remedies may not exist in the event of unauthorized use or disclosure of our confidential information. The disclosure of our proprietary information or trade secrets could impair our competitive position and could have a material adverse affect on our business, financial condition and results of operations. Others may obtain patent protection for technologies that are important to our business, and as a result, our business, financial position and results of operations may be adversely affected. In response to patents of others, we may need to license the rights to use the technology patented by others, or in the event that a license cannot be obtained, design our systems around the patents of others. There can be no assurances as to our ability to obtain any such licenses or to design around the patents of others, and our inability to do so could have an adverse affect on our business, financial position and results of operations.

We offer credit to our customers and, therefore, are subject to significant credit risk.

        We sell our products to a large and diverse customer base. We finance a significant portion of such sales through trade credit, typically by providing 30-day payment terms. As a result, our business could be adversely affected in the event of a deterioration of the financial condition of our customers, resulting in the customers' inability to repay us. This risk may increase if there is a general economic downturn affecting a large number of our customers and in the event our customers do not adequately manage their business or properly disclose their financial condition.

Table of Contents

We intend to explore additional growth through acquisitions.

        As part of our growth strategy, we may continue to pursue the acquisition of companies that either complement or expand our existing business. As a result, we regularly evaluate potential acquisition opportunities, which may be material in size and scope. In addition to those risks to which our business and the acquired businesses are generally subject to, the acquisition of these businesses gives rise to transactional and transitional risks, and the risk that the anticipated benefits will not be realized.

Table of Contents

Risks associated with the foreign suppliers from whom our products are sourced could adversely affect our financial performance.

        The products we sell are sourced from a wide variety of domestic and international suppliers. Global sourcing of many of the products we sell is an important factor in our financial performance. Since the onset of the global economic crisis in 2008, certain of our suppliers, particularly those in the far east, have experienced financial difficulties and we believe it is possible that a limited number of suppliers may either cease operations or require additional financial assistance from us in order to fulfill their obligations. Changes in our relationships with suppliers or increases in the costs of purchased raw materials, component parts or finished goods could result in delays, inefficiencies or our inability to market products. In addition, our profit margins would decrease if prices of purchased raw materials, component parts, or finished goods increase and we are unable to pass on those increases to our customers.

We rely on independent shipping companies to deliver inventory to us and to ship products to customers.

        We rely on arrangements with independent shipping companies, for the delivery of our products from vendors and to customers. The failure or inability of these shipping companies to deliver products, or the unavailability of their shipping services, even temporarily, could have a material adverse affect on our business. We may also be adversely affected by an increase in freight surcharges due to rising fuel costs and added security. This could adversely impact our selling, general and administrative expenses or lead to price increases to our customers which could decrease customer demand for our products.

Changes in accounting rules could have a material adverse impact on our results of operations.

        We prepare our financial statements in conformity with accounting principles generally accepted in the United States. These accounting principles are subject to interpretation by the Financial Accounting Standards Board, the Public Company Accounting Oversight Board, the United States Securities and Exchange Commission (SEC), the American Institute of Certified Public Accountants and various other bodies formed to interpret and create appropriate accounting policies. A change in these policies or a new interpretation of an existing policy could have a significant effect on our reported results and may affect our reporting of transactions.

Changes in Income Tax and Other Regulatory Legislation

        We operate in compliance with applicable laws and regulations. When new legislation is enacted with minimal advance notice, or when new interpretations or applications of existing laws are made, we may need to implement changes in our policies or structure.

        We make plans for our structure and operations based upon existing laws and anticipated future changes in the law. We are susceptible to unanticipated changes in legislation, especially relating to income and other taxes, import/export laws, hazardous materials and other laws related to trade, accounting and business activities. Such changes in legislation may have a significant adverse effect on our business.

We may be subject to litigation.

        We may be subject to legal claims or regulatory matters involving stockholder, consumer, antitrust and other issues. Litigation is subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages or other adverse affects. Were an unfavorable ruling to occur, there exists the possibility of a material adverse impact on our business, financial position and results of operations for the period in which the ruling occurred or future periods.

Table of Contents

We may incur product liability claims which could be costly and could harm our reputation.

        The sale of our products involves risk of product liability claims against us. We currently maintain product liability insurance, but our product liability insurance coverage is subject to various coverage exclusions and limits and may not be obtainable in the future on terms acceptable to us, or at all. We

do not know whether claims against us with respect to our products, if any, would be successfully defended or whether our insurance would be sufficient to cover liabilities resulting from such claims. Any claims successfully brought against us could harmadversely affect our business.financial condition, and if substantial and relating to our products or industry generally, could affect our business as a whole.

RISKS RELATED TO OWNERSHIP OF OUR COMMON STOCK

A significant portion of our voting stock is controlled by our executive officers, directors and beneficial owners of 5% or more of our common stock.

        Our executive officers, directors and beneficial owners of 5% or more of our common stock and their affiliates, in the aggregate, beneficially owned approximately 60%66% of our outstanding common stock as of March 29, 2009.28, 2010. Robert B. Barnhill, Jr., our chairman, president and chief executive officer beneficially owned approximately 25%27% of our outstanding common stock as of March 29, 2009.28, 2010. Should these shareholders decide to act together, they would have the ability to significantly influence all matters requiring shareholder approval, including the election of directors and any significant corporate transaction requiring shareholder approval.

Without approval of our Board of Directors, it may be difficult for a third party to acquire control of the Company. This could affect the price of our common stock.

        Certain provisions of our certificate of incorporation and bylaws, certain arrangements to which we are party, and applicable provisions of the Delaware General Corporation Law (DGCL) may each make it more difficult for or may prevent a third party from acquiring control of us or changing our Board of Directors and management. These provisions include a classified Board of Directors with staggered three-year terms, advance notice bylaws, and limitations on the removal of directors other than for cause, and then only upon the affirmative vote of 75% of our outstanding common stock. In addition, on February 1, 2008, our Board of Directors adopted a stockholder rights plan pursuant to which one preferred stock purchase right was distributed on each common share held of record as of the close of business on February 11, 2008. The rights become exercisable under certain circumstances following the announcement that any person has acquired 20% or more of our common stock, or the announcement that any person has commenced a tender offer for 20% of our common stock (in each case, with certain limited exceptions). Under specified conditions, each right (other than those held by the person or persons acquiring or making a tender offer for our stock, which rights become void under the rights plan) will entitle the holder to purchase, at the exercise price provided for under the plan, our common stock (or if we are acquired in a merger or other business combination, common stock of the acquirer) having a then current value of two times the exercise price. In addition, on February 1, 2008, our Board of Directors amended our bylaws to provide that a special meeting of stockholders must only be called upon a request in writing by the holders of stock of all classes representing at least 50% of the votes possessed by all classes then issued, outstanding and entitled to vote at the meeting. We are also afforded the protections of Section 203 of the DGCL, which will prevent us from engaging in a business combination with a person who acquires at least 15% of our common stock for a period of three years from the date such person acquired such common stock, unless Board of Director or shareholder approval were obtained. Some believe that the provisions described above, as well as any resulting delay or prevention of a change of control transaction or changes in our Board of Directors or management, could deter potential acquirers or prevent the completion of a transaction in which our shareholders could receive a substantial premium over the then current market price for their shares. We, on the other hand, believe that these provisions serve to protect our shareholders against abusive takeover tactics, and to preserve and maximize the value of the Company for all shareholders, and better ensure that each shareholder will be treated fairly in the event of an unsolicited offer to acquire the Company.

Our quarterly operating results are subject to significant fluctuation.

        Our operating results have fluctuated from quarter to quarter in the past, and we expect that they will continue to do so in the future. Our earnings may not continue to grow at rates similar to the growth rates achieved in recent years and may fall short of either a prior fiscal period or investors' expectations. Most of our operating expenses, such as compensation expense, do not vary directly with the amount of sales and are difficult to adjust in the short term. As a result, if sales in a particular quarter are below expectations for that quarter, we may not proportionately reduce operating expenses

Table of Contents

for that quarter, and therefore such a sales shortfall would have a disproportionate effect on our net income for the quarter.

Item 2.    Properties.

        Our corporate headquarters and primary distribution center, known as the Global Logistics Center (GLC), is located in a Company-owned 184,000 square-foot facility north of Baltimore, in Hunt Valley, Maryland. Our sales, marketing and administrative offices are located in leased office space near the GLC. On May 1, 2007, this lease was amended and now expires on December 31, 2012. Monthly rent payments range from $124,700 to $144,600 throughout the lease term. Additional sales and marketing offices are located in leased office space in San Antonio, Texas. Monthly rent there is approximately $7,000 and the lease expires in November 2011. West coast sales and fulfillment is facilitated by our Company-owned 115,000 square-foot Americas Sales & Logistics Center (ALC) located in Reno, Nevada. The ALC is used to configure and fulfill product and supply chain solutions, provide disaster backup for the GLC, and allow for future growth of staffing and increased fulfillment capabilities. On June 1, 2007, we entered into a threefour year lease for 66,000 square feet of office and warehouse space adjacent to our GLC in Hunt Valley, Maryland. Monthly rent for the facility is approximately $35,000. While we anticipate the need for additional space, we believe our existing facilities are generally adequate for our current requirements and that suitable additional space will be available as needed to accommodate future expansion of our operations. The GLC is encumbered by a deed of trust as security for a term loan. See Notes 7 and 19Note 8 to our Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K. Each of our three business segments use all of our properties for either sales or fulfillment purposes.
