PART I

ScanSource, Inc. (the “Company”), incorporated in 1992, is a leading wholesale distributor of specialty technology products, providing value-added distribution sales to resellers in the specialty technology markets. The Company has two geographic distribution segments: one serving North America from the Memphis, Tennessee distribution center, and an international segment currently serving Latin America (including Mexico) and Europe from distribution centers located in Florida and Mexico, and in Belgium, respectively. The North American distribution segment markets automatic identification and data capture (“AIDC”) and point-of-sale (“POS”) products through its ScanSource sales unit; voice, data and converged communications equipment through its Catalyst Telecom sales unit; voice, data and converged communications products through its Paracon sales unit; and electronic security products through its ScanSource Security Distribution unit. The international distribution segment markets AIDC and POS products through its ScanSource sales unit. See Note 11 to the consolidated financial statements of the Company for financial information concerning the Company’s reporting segments and the geographic areas in which the Company operates.

North American Distribution Segment

ScanSource Sales Unit

The ScanSource sales unit markets AIDC and POS products which interface with computer systems used to automate the collection, processing and communication of information for commercial and industrial applications, including retail sales, distribution, shipping, inventory control, materials handling and warehouse management. The bar code family of products is referred to as automatic identification and data capture because it includes all types of portable data collection terminals, wireless products and bar code label printers, in addition to scanners. POS products are those PC-based products that have replaced electronic cash registers in retail and hospitality environments.

ScanSource sales unit vendors include most of the leading AIDC and POS manufacturers, including APG Cash Drawer, Cherry Electrical, Citizen, Cognitive Solutions, Datamax, Elo, Epson America, Hand Held Products, IBM, Intermec, Ithaca Peripherals, Magtek, Metrologic, MMF Cash Drawer, NCR, Pioneer, PSC, Sato, Symbol Technologies, 3M, and Zebra Technologies.

Catalyst Telecom Sales Unit

The Catalyst Telecom sales unit markets voice, data and converged communication systems and is a distributor of Avaya communications solutions, including Avaya Enterprise Communications Group (ECG), Small Market Business Solutions (SMBS) and internet protocol (IP) products. Catalyst Telecom also markets products complementary to the Avaya product line from vendors including Eaton Powerware, Extreme Networks, Plantronics, Polycom, and SpectraLink.

Paracon Sales Unit

The Paracon sales unit markets business communications systems — specifically converged communications and computer communication integration products from manufacturers including Intel, NEC, and Vertical. Converged communications products combine traditional voice technologies with data technologies to deliver business communications solutions that combine computers, telecommunications and the Internet.

ScanSource Security Distribution Unit

The ScanSource Security Distribution sales unit was launched in October 2004 with a focus on hardware distribution of electronic security equipment using the two-tier distribution model, as described below in “Industry Overview”. The product offering includes access control, surveillance, intrusion, and fire-related products, and vendors include Bosch, Datacard Group, Fargo, Image Vault, JVC, Keyscan, and Zebra Card.

International Distribution Segment

The Company’s international distribution segment markets AIDC and POS products exclusively to technology resellers and integrators in the Latin American (including Mexico) and European markets. Key vendors include many of the same vendors that supply the ScanSource sales unit of the North American distribution segment, with the addition of Datalogic.

The international distribution segment commenced operations in November 2001, when the Company acquired a majority interest in Netpoint International, Inc. (“Netpoint”), a Miami-based distributor of AIDC and POS equipment to the Latin American market. In January 2002, the Company commenced operations in Europe with the establishment of a warehouse and sales office in Belgium. In May 2002, the Company purchased ABC Technology Distribution (“ABC”), a distributor of AIDC and POS products based in the United Kingdom, allowing the Company to expand its European operations and expand its sales to former ABC customers in the United Kingdom. On January 1, 2003, ScanSource, Inc. sold its Mexico operations to Netpoint (part of the international distribution segment), a majority-owned subsidiary of the Company. In April 2005, the Company purchased Europdata Connect UK Ltd. (“EDC”), expanding its presence in the UK, Ireland, Sweden, and the Netherlands. The Company has centralized its accounting, information technology and sales management in the Belgium headquarters location.

See “Risks Attendant to Forward Looking Statements” below and Exhibit 99.1 to this report for a discussion of certain risks relating to the Company’s international operations.

Products and Markets

The Company currently markets over 34,000 products from over 100 hardware and software vendors to over 16,000 reseller customers primarily from its central warehouses in Tennessee, Florida, Mexico and Belgium.

AIDC technology incorporates the capabilities for electronic identification and data processing without the need for manual input and consists of a wide range of products, including bar code printers and labeling devices, contact wands, hand-held and fixed-mount laser scanners, mobile and wireless data collection devices, and magnetic stripe readers. As AIDC technology has become more pervasive, applications have evolved from traditional uses such as inventory control, materials handling, distribution, shipping and warehouse management to more advanced applications such as healthcare. POS products include those computer-based systems that have replaced electronic cash registers in grocery, retail, and hospitality environments. POS product lines include computer-based terminals, monitors, receipt printers, pole displays, cash drawers, keyboards, peripheral equipment and fully integrated processing units. Voice and data products include private branch exchanges (PBXs), key systems, and telephone handsets and components used in voice, fax, data, voice recognition, call center management and IP communication applications. Converged communication products combine voice, data, fax, video conferencing, and speech technologies to deliver communications solutions that combine computers, telecommunications and the Internet. Converged communications products include telephone and IP network interfaces, PBX integration products and carrier-class board systems-level products. Electronic security products include identification, access control, surveillance, intrusion, and fire-related products.

See “Management’s Discussion and Analysis” in the Company’s Annual Report to Shareholders for the fiscal year ended June 30, 2005 for a discussion of the amount of the Company’s net sales contributed by product categories.

Industry Overview

The distribution channels for specialty technology products generally consist of manufacturers, wholesale distributors such as ScanSource, resellers and end-users. In recent years, these distribution channels have evolved through three stages: (i) direct sales by manufacturers to end-users; (ii) single-tier distribution in which manufacturers sell to resellers who, in turn, sell directly to end-users; and (iii) two-tier, or wholesale distribution, in which manufacturers sell to wholesale distributors, including ScanSource, who sell only to resellers who, in turn, sell directly to end-users.

Currently, the technology products wholesale distribution channel is served by both broadline and specialty distributors. The broadline distributors are engaged primarily in conventional order fulfillment and typically offer few value-added services. The specialty distributors in the geographic areas in which ScanSource operates, tend to be regional and smaller than ScanSource.

Competition among an expanding number of manufacturers has caused product prices to decrease and product applications to expand, which has resulted in an increasing number of resellers entering the market in order to support a broader base of potential end-users. As the number of resellers and end-users has grown, competition among manufacturers and within the reseller channel has intensified, resulting in a less orderly market structure. As a result of the transition of specialty technology products to open-systems (whereby a variety of manufacturers’ products can be configured together to create a system solution), both manufacturers and resellers have become more dependent upon wholesale distributors such as ScanSource for the organization and maintenance of an efficient market structure.

In addition, manufacturers that face declining product prices and rising costs of direct sales increasingly rely upon value-added wholesale distributors by outsourcing certain support functions, such as product assortment, delivery, inventory management, technical assistance, and marketing. At the same time, shortened product life cycles and the introduction of new products and applications have caused resellers increasingly to rely on wholesale distributors for various inventory management, financing, technical support and related functions. The Company believes that as the reseller market grows and becomes more fragmented, and as specialty technology products continue to transition to open systems, the wholesale distribution channel in which the Company operates will become increasingly more important.

Vendors

The Company’s merchandising department recruits vendors and manages important aspects of its vendor relationships, such as purchasing arrangements, cooperative marketing initiatives, vendor sales force relationships, product training and the monitoring of rebate programs and various contract terms and conditions. The Company generally enters into non-exclusive distribution agreements with vendors. These agreements typically provide the Company with stock rotation and price protection provisions that may mitigate the risk of loss from slow moving inventory, vendor price reductions, product updates or obsolescence. Some of these distribution agreements contain minimum purchase requirements that the Company must meet in order to receive preferential prices. The distribution agreements are generally terminable on 30 to 120 days notice by either party.

Customers

The Company’s reseller customers currently include over 16,000 active value-added reseller accounts (“VARs”) located in the United States, Canada, Mexico, Latin America and Europe. The largest customer accounted for less than 5% of the Company’s total net sales in fiscal 2005. The Company generally targets two types of reseller customers:

Specialty Technology VARs.

These resellers focus on selling specialty technology products as tailored software or integrated hardware solutions for their end-users’ existing applications or incorporating specialty technology products into customized technology solutions for their end-users. Primary industries served by these resellers include manufacturing, distribution, health care, pharmaceutical, hospitality, government, convenience, grocery, financial, and other retail markets.

Networking or PC VARs.

These resellers develop computer solutions and networking for their end-users’ microcomputer needs. They typically have well-established relationships with end-user management information system directors and are seeking additional revenue and profit opportunities in related technology markets, such as AIDC, POS, security, or communications.

Sales and Electronic Commerce

The Company’s 223-member sales department consists primarily of inside sales representatives located in the United States, Canada, Mexico, Belgium, France, Germany, the United Kingdom, and the Netherlands. In order to build strong customer relationships, each active reseller is assigned to a sales representative. Each sales representative negotiates pricing directly with his assigned customers. The Company also employs several business development representatives who are responsible for developing technical expertise within broad product markets, recruiting customers, creating demand, and reviewing overall product and service requirements of resellers. Each sales representative and business development representative receives comprehensive training with respect to the technical characteristics of each vendor’s products. This training is supplemented by frequent product seminars conducted by vendors’ representatives and bi-weekly meetings among product, marketing and sales managers.

Increasingly, customers rely upon the Company’s electronic ordering and information systems, in addition to its product catalogs and frequent mailings, as sources for product information, including availability and price. Through the Company’s website, most customers can gain remote access to the Company’s information systems to check real-time product availability, see their customized pricing and place orders. Customers can also follow the status of their orders and obtain UPS and FedEx package tracking numbers from this site.

Marketing

The Company provides a range of marketing services, including cooperative advertising with vendors through trade publications and direct mail, product catalogs for each of the North American, European and Latin American markets, periodic newsletters, management of sales leads, trade shows with hardware and software companies and vendors, direct mail and sales promotions. In addition, the Company organizes and operates its own seminars teaming with top vendors to recruit prospective resellers and introduce new applications for the specialty technology products it distributes. The Company frequently customizes its marketing services for vendors and resellers.

Value-Added Services

In addition to the basic order fulfillment and credit services that conventional wholesale distributors typically provide to resellers, the Company differentiates itself by providing an array of value-added services and business tools that assist resellers to provide more complete solutions and improve customer service. Such services include system integration, professional services, and technical support.

Operations

Information System

The Company’s information system is a highly scalable, centralized processing system capable of supporting numerous operational functions including purchasing, receiving, order processing, shipping, inventory management and accounting. Sales representatives rely on the information system for on-line, real-time information on product pricing, inventory availability and reservation, and order status. The Company’s warehouse operations use bar code technology for receiving and shipping, and automated UPS and FedEx systems for freight processing and shipment tracking, each of which is integrated with the Company’s information system. The customer service and technical support departments employ the system for documentation and faster processing of customer product returns. To ensure that adequate inventory levels are maintained, the Company’s buyers depend on the system’s purchasing and receiving functions to track inventory on a continual basis.

Central Warehouse and Shipping

The Company’s 367,000 square foot warehouse facility, located near the FedEx hub facility in Memphis, Tennessee, serves all of North America. The Company utilizes a third party warehouse located in Liege, Belgium that serves all of Europe, including the United Kingdom. The Company has additional warehouse facilities in Florida and Mexico, which serve Latin America (including Mexico). The Company believes that its centralized distribution creates several advantages, including: (i) a reduced amount of “safety stock” inventory which, in turn, reduces the Company’s working capital borrowings; (ii) an increased turnover rate through tighter controls over inventory; (iii) maintenance of a consistent order-fill rate; (iv) improved personnel productivity; (v) improved delivery time; (vi) simplified purchasing and tracking; (vii) decreased demand for management personnel; and (viii) flexibility to meet customer needs for systems integration. The Company’s objective is to ship all orders on the same day, using bar code technology to expedite shipments and minimize shipping errors. The Company offers reduced freight rates and flexible delivery options to minimize a reseller’s need for inventory.

Financial Services

The Company routinely offers competitive credit terms relative to the specific geographic area for qualified resellers and facilitates various third party financing options, including leasing, flooring, and other secured financing. The Company believes this policy eliminates the customer’s need to establish multiple credit relationships with a large number of manufacturers.

Competition

The markets in which the Company operates, as identified above, are highly competitive. Competition is based primarily on factors such as price, product availability, speed and accuracy of delivery, effectiveness of sales and marketing programs, credit availability, ability to tailor specific solutions to customer needs, quality and breadth of product lines and services, and availability of technical and product information. The Company’s competitors include regional and national wholesale distributors, as well as hardware manufacturers (including most of the Company’s vendors) that sell directly to resellers and to end-users. In addition, the Company competes with master resellers that sell to franchisees, third-party dealers and end-users. Certain of the Company’s current and potential competitors have greater financial, technical, marketing and other resources than the Company and may be able to

respond more quickly to new or emerging technologies and changes in customer requirements. Such competition could also result in price reductions, reduced margins and loss of market share by the Company.

Competition has increased for our ScanSource and Catalyst Telecom sales units in the last three years as broadline and other value added distributors have entered into the specialty technology markets.

Employees

As of June 30, 2005, the Company had 887 employees located in North America, Latin America (including Mexico) and Europe, none of whom was a member of an industry trade union or collective bargaining unit. The Company considers its employee relations to be good.

Service Marks

The Company conducts its business under the trademarks and service marks “ScanSource”, “Catalyst Telecom”, “Paracon”, “Partner Services”, and “ScanSource Security Distribution”. The Company has been issued registrations for the service marks “ScanSource” and “Catalyst Telecom” in countries in its principal markets. These trademarks and service marks do not have value assigned to them and have a designated indefinite life. The Company does not believe that its operations are dependent upon any of its trademarks or service marks. The Company also sells products and provides services under various trademarks, service marks and trade names to which reference is made in this report that are the property of owners other than the Company. Such owners have reserved all rights with respect to their respective trademarks, service marks and trade names.

Acquisitions

The Company acquired EDC in April 2005. See Note 12 of Notes to Consolidated Financial Statements for information concerning this acquisition.

Controls and Procedures.

Evaluation of Controls and Procedures

The Company maintains disclosure controls and procedures designed to ensure that information required to be disclosed in reports filed or submitted under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. As of the end of the period covered by this report, the Company’s Chief Executive Officer and Chief Financial Officer evaluated, with the participation of management, the effectiveness of the Company’s disclosure controls and procedures as required by Rule 13a-15 or 15d-15 of the Exchange Act. Based on the evaluation, which disclosed no material weakness, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures are effective. There were no changes in the Company’s internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Rule 13a-15 or 15d-15 of the Exchange Act, that occurred during the Company’s most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Limitations on the Effectiveness of Controls

The Company maintains a system of internal accounting controls to provide reasonable assurance that assets are safeguarded and that transactions are executed in accordance with management’s authorization and recorded properly to permit the preparation of financial statements in accordance with accounting principles generally accepted in the United States. However, the Company’s management, including the Chief Executive Officer and Chief Financial Officer, does not expect that the Company’s disclosure controls or internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty. Breakdowns in the control systems can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.
